ANALYSIS OF PER CAPITA GREENHOUSE GAS EMISSIONS IN EU-25 COUNTRIES pag. 3-8

J. Lazányi

The European Union is committed to global efforts to reduce the greenhouse gas emissions from human activities. In the first step countries accepted to reduce greenhouse gas emissions by around 5 % compared to 1990 levels, but in the longer-term, global emissions of greenhouse gases will need to be reduced by approximately 70 % and it forces the countries to update national emission inventories each year. An analysis of per capita GHG emission has been made with 25 member state of EU responsible for about 41 % of total greenhouse gas emissions. The 15 member states that made up the EU until 1 May 2004 are committed to reducing their combined emissions of greenhouse gases by 8 % from 1990 levels by the end of the Kyoto Protocol’s first commitment period 2008–12. The 10 new Member States are not covered by the EU target but have their own reduction target of 6 % or 8 % under the protocol, except for Cyprus and Malta, which have no targets. Many of the EU countries have greenhouse gas emissions greater than 6 t CO 2 -eq/cap. In 2004, the most important sources of greenhouse gas emissions in the EU-25 include energy industries (electricity sector and refineries) (28 %), transport (21 %), industry (without energy sector) (20 %), households and SMEs (17 %), agriculture (10 %) and other sector (4 %). Directive 2003/87/EC established a scheme for GHG emission allowance trading within the community in order to promote reductions of GHG emissions. EU scheme allows companies to use credits from Kyoto’s project-based mechanisms, joint implementation (JI) and the clean development mechanism (CDM), to comply with their obligations under the scheme. This means the system not only provides a cost-effective means for EU-based industries to cut their emissions but also creates additional incentives for businesses to invest in emission-reduction projects in developing countries. The transfer of advanced, environmentally sound technologies to other member states and developing nations, gives tangible support to their efforts to achieve sustainable development, but per capita GHG emission data indicate the importance of grouping to share reduction between global regions and countries.

J. Subić, Nataša Cecić, D. Cvijanović

This paperwork relate to Community of Pančevo area which were insert on black list of ecological points in Republic of Serbia due to spacious endanger of natural resources. Objects of this research are water and soil as unregeneration natural resources on which exist all planet life, including state and nation and all economy of any area. With regard of living in technological prosperity period and industrialization and in that way water as natural resources recipients a huge quantity of waste water, and also exposed to another origin of pollution, problems with evaluation of water quality for irrigation get bigger in last decades. In the nature are less water of good quality with aggravation trend. Negative impact of mineral water on soil and plants lead to need for determination and evaluation of water irrigation quality. Criteria for evaluation of water quality are often local character, and distinction is understandable, because conditions between individual region are different. This paperwork include three Experimental fields on three region Community of Pančevo. Experimental fields are under greenhouses and in period form October 2006 to April 2007 will be produced vegetables lettuce, spinach, onion and radish. First experimental field will be in Glogonj village, second in Banatski Brestovac village and third experimental field belongs secondary agricultural school „Josif Pančić“ in Pančevo. In greenhouses will be introduced modern technology of production with micro sprinkling irrigation systems. Research activity during realization of this project impact of different water quality with three different areas and three different soil type on quantity and quality of produced vegetables and yield

P. Vuković, Slavica Arsić, Lana Ivanović

Since pollution has become disturbing in all parts of the world, it is important to identify all aspects of pollution and what affects it, in order to regulate and amend the problem. Continuous technological and technical progress, development of chemistry, plant breeding using chemicals and fertilizers, animal breading using large amounts of physiological waste, liquid and solid manure, are all significant causes of pollution. Therefore, many companies make programs for ecological and sustainable agriculture. This paper aims at identifying the conditions that are important for organic production, but it also discusses natural resources and new agricultural techniques used in order to reduce pollution. It analyses the conditions for controlled production and identifies the measures necessary for sustainable development of high quality food, protection of the eco-system and soil quality .

Cornel Domuţa, Gheorghe Ciobanu, Maria Şandor, Alina Samuel, Cornelia Ciobanu, Nicu Cornel Sabău, V. Şcheau, Ioana Borza, Cristian Domuţa

The paper is based on the research carried out in the second cycle of the experiment placed in Oradea in 1999. The use of lupine mixed with oat determined the improvement of the macrostructural stability compared to lupine pure crop. The use of the mixture also determined the improvement of other physical parameters, slightly improvements of the chemical parameters of fertility of the soil, the improvement of the enzymatic activity; as a result, the soil quality enzymatic index improved, a value of 455 compared to one of 441.49. The green manure pure crop ensures a 100% rate of success; the start second crop takes risks when made after 10 th of July. In average, during 2004 to 2006, the lupine + oat variant assured statistically yield gain in the maize crop, compared to the lupine pure crop variant; these yield gains were registered both in the wheat-maize crop rotation and the crop rotation which included clover; the yield gains were also registered in the backgrounds studied (N 0 P 0 K 0 ; N 90 P 90 K 60 ). The maize’ water use efficiency had higher values in the variant fertilized with lupine + oat in both crop rotations and both background. The results obtained reveal that the use of lupine mixed with oat improves the soil’s characteristics. They also lead to maize yield gains statistically assured, compared to lupine pure crop and the improvement of the maize’ water use efficiency.

THE ENVIRONMENTAL IMPACT OF THE INDUSTRIAL PIG FARMS FROM THE MAŞLOC COMMUNE pag. 33-36

Clarisa Liuba, G. Eleş

This study present the environmental impact of the industrial pig farms and the high pollution degree of the environmental factors (water, air, soil and people). Reprehensible management and carelessness about the potential dangers of the waste and the failure to install decent pollution control equipment and treat the waste resulted in violations of the permitted limits for phosphorus, faecal coliform and other pollutants. One way that pig farms waste pollutes is through the sprayfield system, which is supposedly meant to fertilize crops. But often too much of the untreated liquid manure is sprayed, resulting in crop damage and contaminated soil, groundwater as well as pose a serious health risk to the small segment of the population subject.

In this paper we studied the processes that generate acidity in the soils and the factors that determinate it. For this we analysed a lot of pedological profile, a sample from Obreja and Glimboca, in Bistra Hydrographyc Basin, Caraş- Severin County. From the pedological profile analyses we established that the acid soils, like luvosoils and districambosoils are predominant in the researches area and their acidity are determinate by the bases cations debasification and it forms a impermeable water horizon, Bt, that leads in time to oxide-reduction processes that will generate a soil acidification.

he researches regarding the heavy metals contents in Bistra Hydrographic Basin, from Caraş-severin County, demonstrated that, generally, here the values exceed the normal values. Because these values were founded along the Couloir we considered that geogene hypothesis pollution exists. It is known that Ruşchiţa area is a mineralogical area. The pollutant activity of S.C. GAVAZII STEEL S.A. Oţelu Roşu is considered insignificant. If this pollutant activity would exist, the maximum values would be founded about the locality with a reduced tendency towards the valley extremity, fact that does not exist.

PELLIC VERTISOLS AND VERTISOLS IN TIMIŞ COUNTY pag. 81-84

R. Bertici, Gheorghe Rogobete, D. Beutură, Adia Grozav

In accordance with the new Romanian Taxonomy Soil System, there are two types of soil in the soil class Pellisol: Pellosol and Vertosol. Both of them are deep clayey soils (>45% and >30% clay) but in the Vertosol dominated clay minerals such as smectites, that expand upon wetting and shrink upon drying. Deep wide craks form when the soil dries out and swelling in the wet season, but in the Vertosol these phenomena are generalized and the slichensides have 10-60 0 inclination. The correlation with WRB-SR and USDA-ST is very difficult and also is the separation in the soil survey between Pellic Vertisils and Vertosols in Timiş County.

TOLERANCE TO CADMIUM AND PHYTOCHELATINS SYNTHESIS IN AGROSTIS TENUIS pag. 85-90

Carmen Cimpeanu, Irina Grebenişan

The paper has as aim the cellular and biochemical identification of some proteins (phytochelatins and iso-phytochelatins) able to bind the cadmium ions. For this, cell suspensions of root callus proceeded from an Agrostis tenuis ecotype (harvested from a metalliferous area, polluted with heavy) were obtained. The cell suspensions were treated with different cadmium concentrations. One can ascertain that the Agrostis ecotype, from polluted area, has the ability to synthesize phytochelatins and, it manifests an increased tolerance to cadmium ions (solution concentrations of 100 μM). One can conclude that phytochelatins synthesis has an important role into plant tolerance to cadmium.

STUDY OF THE ABUNDANCE INDEX OF PHYSCIA AIPOLIA AND XANTHORIA PARIETINA IN CORRELATION WITH THE CONCENTRATION OF ENVIRONMENTAL PB AND ZN pag. 119-122

B. Lixandru, Smaranda Mâşu, C. Bogatu, G. Trandafir, Anca Diana Pricop, C. Onica

In a period of 12 weeks, samples of white poplar bark (Populus alba), naturally covered with lichens of the Xanthoria parietina and Physcia aipolia species, and were polluted under lab conditions with different levels of Zn and Pb. The pollution was done through the watering and nourishing solutions and the level of the two pollutants varied between 20 – 240 mg Zn/L and 10-120 mg Pb/L. The reaction and adaptation mode of the two lichen species was assessed through the phytomass abundance study, evaluated according to the bark surface covering degree. The watering performed to pollute and nourish was done twice a week. Measuring the surface covering degree was done through planimetry at 3, 6, 9, and 12 weeks. Our results evidenced great sensitivity of the Physcia aipolia species to high pollution levels of Pb and ZN. The covering degree is reduced after 3 weeks to 60%, to 95% after 6 weeks, and at 9 weeks, this species completely disappeared. After an accommodation period of about 3-4 weeks, when the covered area remained the same, the covering degree of the surface by the Xanthoria parietina species increases by 10% at 6 weeks, reaching 15% at 12 weeks. These results lead to the idea that the careful study of the lichen abundance may offer in an easy way signal-news about the gaseous pollution level of the environment.

In this paper work, we present the results of our studies concerning the effects of the herbicides linuron, dimetenamid and treflan upon the symbiotic nitrogen bacteria applied in seeds. We have tested herbicide action for 4 concentrations: normal concentration – the normally recommended herbicide dose, double concentration (2x normal dose), triple concentration (3x normal dose), and half of the recommended dose (1/2x normal dose). The results achieved made evident that strains have different reaction to linuron and dimetenamid, and these reactions are not correlated with the concentration. We may explain this situation through the different strain capacity of tolerance under the action exerted by these herbicides.

The goal of the studies and research was to test the contribution of organic fertilisers to the dynamic rebalancing process of soil fertility for the conversion to an ecological agriculture system. In order to achieve our goals, we set field trials within which we tested the impact of an organic fertiliser at different rates (manure: 40, 60, and 80 t/ha) on the regime of soil nutrients and on the rebalancing of soil fertility. There is a lot of research going on in the field, but there are no concrete climate and soil conditions to do it; therefore we need to approach this direction too in the Timisoara area. Research results are favourable and they are readily applicable for a proper conversion to ecological agricultural systems.

ON THE USE OF RESIDUAL CALCIUM AND MAGNESIUM IN SOIL TREATMENT AND PLANT FERTILISATION pag. 183-186

Hortensia Rădulescu, Lidia Taubert, N. Băghină

The industrial process of producing magnesium carbonate and oxide from dolomites by carbon dioxide leaching generates calcium carbonate as waste. Besides calcium carbonate, this precipitate contains magnesium carbonate, which can be useful inagriculture as a soil amendment and fertilizer for low fertile acid soils. The paper shows the effects of soil treatment with four different doses of industrial waste concerning the soil reaction and calcium - magnesium content, simultaneously with the growth process of green oat plants and their calcium - magnesium uptake. The obtained results indicate that soil reaction turns from acid to neutral, while the established increase for calcium soil content reached 51% and 260% for magnesium content, both generated by the highest experimented waste dose. For green oat plants, the results showed an increase by 117% for calcium uptake and 72% for magnesium uptake. The influence determined on the growth reveals a beneficial effect on germination and number of risen plants, a taller size of plants as well as a decrease of dry matter content at harvest time.

Two short definitions of Remote Sensing might be presented as follows: “To study or measure an object without being in physical contact with it” or “feeling without touching”. As defined above, the term generally implies that the sensor is placed at some considerable distance from the sensed target, in contrast to close-in measurements made by "proximate sensing." sometimes given as "in situ" sensing. Remote sensing means aerial photography too. Aerial platforms are primarily stable wing aircraft. Aircraft are often used to collect very detailed images and facilitate the collection of data over virtually any portion of the Earth's surface at any time.

STUDY REGARDING URBAN NOISE DURING THE DAY IN TIMISOARA pag. 199-206

Adina Horablaga, E. Putnoky

Noise affects population from physical and psychical point of view. If the 40 dB level noise provokes sleeping disorders , a 55 dB level noise creates significant disturbance. At greater levels of 65 dB, noise affects seriously human health, acting in the first place on cardiovascular system and could get to (or aggravate) affections as hypertension, ischemia and others. At levels over 80 dB noise produces progressive and cumulative deterioration of hearing even if is for short time exposure, like minutes. These aspects are underlining impact exposure adjustment importance at noise on population and establishing clear limits for level noise. In general the 50 dB value is considered as being the most adequate maximum limit admitted during day time for equivalently exterior buildings noise level, in urban environment. In this paper we try to emphasize the significant impact of road traffic in the urban noise generation and the fact that urban noise is the only environmental factor that degrades its quality with the passing of time.

ECONOMIC AND ECOLOGICAL OPPORTUNITIES AND LIMITATIONS OF VALORISING FALLOWS IN THE FĂGET – MARGINA – COŞAVA AREA (TIMIS COUNTY, ROMANIA) pag. 237-239

Daniel Simion Bistrean, Iacob Borza, Gicu Gabriel Arsene

In this paper, we approach an issue of importance in ecological reconstruction related to the dynamics of plant species on fallows in the Faget – Margina – Cosava area (Timis County). The area under study covers 400 km 2 if we take into account all the fallows aged 1-7 after grain or tillage crops. In the study of the flora, we used the two steps – field and lab – and phyto-coenologic research in the area are based on the principles of the Central-European floristic school with broad application in the study of the vegetal cover in Europe and applied for the first time in Romania by Borza (1984). As a result of the study on the sampling areas we managed to inventory the superior plant species on the fallows and the characteristics of the flora and vegetation (number of families, number of species, height of the vegetal cover, stratification, and mosaic-like configuration), and phyto-geographical, biological, ecological, and economic indices. In this paper we also refer to the evolving trends of the phyto-coenoses, the changes it undergoes, its dynamics, and man-made activities

THE INFLUENCE OF CONVENTIONAL AND REDUCED SOIL TILLAGE AND DIFFERENT FERTILIZATION TREATMENTS ON SOIL BIOLOGICAL PROPERTIES UNDER CROPPING OF COMMON PEAS pag. 247-252

Milan Macák, Štefan Týr, Jozef Smatana, Eva Demjanová, Eva Candráková

The aim of this study was to evaluate the influence of conventional and reduced tillage and fertilization on seasonal dynamics of basal respiration, soil organic matter and total content of nitrogen in topsoil layer by growing of common pea. The results refer to 2001-2003 years. The experimental site belongs to warm and moderate arid climatic region in the south-west of Slovakia. Common pea was growing in crop rotation: clover (Trifolium pratense L.) - winter wheat (Triticum aestivum L) - common pea (Pisum sativum L.) - maize (Zea mays L.) - spring barley (Hordeum vulgare L.) under different tillage and residue management practices. Three fertilization management practices as follows: 0-zero level without fertilization, F- mineral fertilizer calculated to the designed yield level, PR - incorporation above-ground plant material with mineral fertilizer for the balance equilibrium level. Mouldboard ploughing (0.2-0.22m) and disking (0.10-0.12m) was used. The soil samples were collected from the 0.075m topsoil layer three times (spring, summer and autumn samples). No significant differences of soil basal respiration between conventional (22.7 mg/1000g/day) and reduce tillage (23.4 mg/1000g/day) in topsoil layer has been noted. The average content of C ox was in interval 1.04%-1.16% without significant influence of tillage treatments. The significant changes of C: N ratio were influenced predominantly by variability of N t content. The high level of basal respiration and flux of CO 2 from unfertilized zero treatments and treatments with mineral fertilization (23.4 - 22.07 mg/1000g/day) are serious threat for the soil organic matter pool from long term perspective.

THE INFLUENCE OF SOIL TILLAGE ON SOIL MOISTURE PARAMETERS UNDER CROPPING OF MAIZE pag. 253-258

Jozef Smatana, Milan Macák, Eva Demjanová, Jana Porhajašová

The aim of the study was to determine the main factors influencing the variability of soil moisture under canopy of maize growing in monoculture and in crop rotation subjected to conventional and reduced tillage treatments. The experimental sites belong to warm and moderate arid climatic region with long term average precipitation 580 mm and 9.6 ˚C temperature and 173 m altitude. The maize was growing in following crop rotation: winter wheat (Triticum aestivum L.) – maize (Zea mays L.) – spring barley (Hordeum vulgare L.) – common pea (Pisum sativum L.). The mouldboard ploughing (conventional tillage) to the depth0.3 m and shallow loosening to the depth 0.1 m and its influence on soil moisture in six layer has been evaluated. Samples were taken five times per year with tree replication in six layers (each 0.1m thick). Seasonal dynamics with influence of weather and growing crops have been ascertained. According three year field trials we confirm no significant differences of soil moisture between primary conventional tillage and reduced tillage treatments under canopy of maize growing in crop rotation and growing as single cropping. Total average of moisture content under reduced tillage revealed the less infiltration rate with comparison to conventional mouldboard ploughing. The highest variability of soil moisture was induced by date of sampling and crop rotation which is important tool for better management of soil moisture balance under canopy of maize.

EFFECTS OF NITROGEN FERTILISING ON THE DYNAMICS OF MINERAL NITROGEN IN THE SOIL UNDER MAIZE INBRED LINES pag. 259-268

Zdravko Hojka, Ivica Đalović, Mirko Grubišić

The study was carried out in the experimental filed of the Maize Research Institute, Zemun Polje, on calcareous chernozem in the period 2001-2003. The traits of two maize inbred lines (L 1 –FAO 400 and L 2 –FAO 600) were observed in dependence on the two fertiliser variants: N o –control without fertilising; N min –PK (const.) + fertilising in spring on the basis of the Nmin method, and forms of applied nitrogen: Urea (amidic form), KAN (ammonium-nitrate form) and (NH 4 ) 2 SO 4 (ammonium form). The highest amount of (NH 4 +NO 3 )–N in the soil (0–120 cm) in the silking stage of maize inbred lines was recorded in 2002 (72.6 kg ha -1 ), under the inbred line L 2 (84.0 kg ha -1 ) and in the treatment with Urea (86.4 kg ha -1 ). The amount of –N and (NH 4 +NO 3 )–N in the soil (0-120 cm) measured at the end of the growing season of observed maize inbred lines was the highest in the second year of investigation (48.9 and 55.8 kg ha -1 , respectively). The application of nitrogen in the amidic form highly significantly affected the increase of the amount of accessible nitrogen in the soil at the end of the growing period in the inbred L 1 (46.3 kg ha -1 ), while the application of different nitrogen forms did not express statistical significance in the inbred L 2

EFFECT OF FERTILIZATION ON MICROBIAL ABUNDANCE IN SUGARBEET RHIZOSPHERE pag. 269-272

Nastasija Mrkovački, Jelena Marinković, Nikola Čačić

Microorganisms are a heterogeneous group of organisms whose enzymatic systems take 60-90% of the total metabolic activity in soil. Dominance of certain groups of microorganisms affects the processes of soil synthesis and decomposition and it determines the quality of soil and its applicability for the production of safe food. The nonsymbiotic nitrogen fixer Azotobacter is an obligate aerobe living in the soil, the rhizosphere and the plant root. The ability of various strains to fix atmospheric N positively affects plant growth and yields. In this study we have determined the abundance of azotobacter, fungi, actinomycetes and the total number of microorganizms in sugarbeet rhizosphere. Simultaneously we studied the effect of application of nitrogen fertilizer, manure and harvest residues. Samples of rhi-zosphere soil were taken three times in the course of growing season (May, July, September) the ex-periment included two variants (inoculated with azotobacter and noninoculated) in four fertilization levels (nonfertilized control, 50, 100, 150 and 200 kg N/ha), in five replication. The results of the stu-dy for all four fertilization types and all four levels of added N showed that azotobacter abundance was higher in inoculated treatments than unino-culated ones. The highest percentage increases of azotobacter numbers, total microbial abundance and number of fungi and actinomycetes were recor-ded in the inoculated treatments with barnyard ma-nure, NPK fertilizer, and barnyard manure plus harvest residues, respectively. In inoculated and uninoculated treatments alike, the highest azoto-bacter abundance was found in the treatment with no N added, while the lowest was recorded in the treatment with 200 kg N/ha added. The highest total microbial abundance was obtained with 100 kg N/ha in inoculated treatments and 200 kg N/ha in uninoculated ones.

HUMUS CONTENT IN PSEUDOGLEY SOIL DEPENDING ON LAND USE pag. 273-276

Miodrag Jelić, Goran Dugalić, B. Gajić, Ivica Đalović

The paper presents data on humus contents in 109 profiles of pseudogley soils in Kraljevo environs under three different forms of land use: arable land, meadow and forest. Soil analysis showed that forest pseudogley soils had the highest content of humus in the humus horizon, 5.99% on the average, while meadow soils followed with 3.37% and arable land with the lowest average humus content of 3.31%. The high content of humus and a tendency of its increase in forest pseudogley soils indicate deteriorating conditions regarding the mineralization of organic matter, which leads to intensification of its accumulation in soil. Well aerated arable land was found to undergo more intensive mineralization of organic matter and more intensive utilization, which decreases the content of humus. In the subhumus horizon, humus content was considerably lower, 1.99% on the average in forest soils, 1.27% in arable land and 1.15% in meadow soils. Humus contents were also found to vary considerably, their values in the humus horizon ranging from 2.85% to 9.68% in forest soils, from 2.01 to 6.03% in meadow soils and from 2.02 to 4.63% in arable land soils. In the subhumus layer of the profile, the most evident vatriation was registered in the arable land variant (0.44-4.01) of pseudogley (0.24-2.04). This high variation of humus contents in the pseudogley soils examined, especially forest soils, indicate very different amounts of organic residues as well as different conditions of their degradation, accumulation and humification

THE ROLE OF FERTILISERS IN CONSERVING SOIL FERTILITY pag. 277-284

Gorica Cvijanović, Ivica Djalović, Miladin Vesković, Drago Cvijanović

In order to maintain the existing level of the soil fertility, nutrients taken out are necessary to be returned to the soil by the yield. It is allowed to use all available sources in the course of returning of nutrients taken out. This paper presents results gained on the effects of fertilisation methods on the yield of the maize hybrid ZP SC 704, then on the dynamics of organic matter in the soil and the abundance of important systemic and physiological groups of microorganisms that provide soil biogeny. The following fertilisers were applied in the maize crop: mineral fertilisers in the rates of 332 and 664 kg ha -1 , ploughed down stover, as an organic matter (each year in the amount of 8,000 kg ha -1 ), combinations of mineral nitrogen and stover ploughed down, manure in the amount of two-three animal units per hectare. It was determined that observed parameters (amount of organic matter, degree of organic matter transformation into soil organic matter, the abundance of certain systemic and physiological groups of microorganisms), as well as, the nitrogen content, were significantly increased in variants with ploughed down organic matter and mineral fertilisers. According to obtained results it was determined that a long term application of mineral fertilisers did not significantly affect the changes of the organic matter content in the soil nor it decreased the soil productivity. A long term application of organic fertilisers in the form of stover and manure very significantly increased the content of organic mater and elements of biogeny in the soil, whereby a positive effect of the combination of organic mater and mineral fertilisers was particularly pronounced. Such a method of fertilising in the crop production undoubtedly satisfies the fundamental principles of organic agriculture (organic food production with the ecological and economical effect).

Through surface excavation of coal at mining excavation Sărmăşag, Sălaj County, is mainly degraded, eutricambosoil molic and through the levelling the dumps is formed the typical entiantrosoil. As further investigation regarding the enzymatic activity of entiantrosoils from Transylvania, this paper presents the enzymatic activity of entiantrosoils which results from mining excavation Mirsid, Sălaj County. To fulfil the aim proposed soil samples have been taken from two profiles on three depths 0-20 cm, 40-60 cm, and 80-100 cm which have been according to the extent laboratory methodology for laboratories of soil biology. The results show that the enzymatic activity to these three depths is very low in comparison with the enzymatic activity of areas degraded soil (molic eutricambosoil). The values of dehydrogenase vary between 0.20 and 0.80 limits, the values of catalase vary between 10 and 85 and the saccharose values vary between 0.15 and 0.35. We have to mention that we cannot make any kind of correlation between these values and the soil sample depths. This thing can be explain through the heterogeneity of the dump material. Without a selective uncovering, the vegetable layer frequently reaches in the depth.

Increasing yields and agricultural lands fertility are directly determined by detailed knowledge of soil solidification process, evolution, and supply with main nutrients. Previous researches concern numerous analytic data for a period of over 40 years an interval in which numerous changes have occurred both in soil features ad in research methodology, mapping, and improvement. A soil features are dynamic and in concordance with soilification conditions, it is imperious to re-evaluate physical and chemical properties, nutrient supply condition and yielding capacity of the main soil in the Timiş county.

ESSAI DE DIFFERENCIATION DES POPULATIONS DE CARABUS (EUCARABUS) ULRICHI GERM. DU BANAT pag. 395-400

Jean Barloy, Florin Prunar

Au Banat, dans les entomocénoses du Genre Carabus L., Carabus (Eucarabus) ulrichi Germ. constitue presque la moitié des effectifs. Cette abondance explique le grand nombre de taxons décrits mais souvent invalidés faute de critères précis. L’étude présentée tente de différencier diverses populations du Banat, par référence a des origines roumaines plus septentrionales et en retenant des critères morphométriques et de polychromie (pourcentage d’individus non cuivreux bronzé). Les critères biométriques les plus pertinents semblent être le ratio pronotal h/l (h = hauteur, l = largeur maximale) et le rapport de forme (h/l) x (L/l) ou L = longueur de l’imago et l = plus grande largeur des élytres.

Au Banat C. (Eucarabus) obsoletus Sturm 1815 assez localisé est représenté par deux sous espèces : - ssp. carpathicus Palliardi 1825 rencontré aux piémonts des Monts Semenic et Poiana Rusca et sa forme d’altitude euchromus dans la partie sommitale des mêmes massifs montagneux. - ssp. fossulifer Fleischer 1839 avec sa forme paranagyagensis Lie 1990 dans les lisières forestières bordant la rivière Mures. La distinction entre euchromus et carpathicus porte essentiellement sur les dimensions, enchromus ayant un pronotum légèrement plus transversal. Avec l’abaissement de l’altitude, la taille s’accroît et le taux de mélanisation augmente. La forme paranagyagensis diffère de carpathicus par des élytres proportionnellement plus larges (ratio L/l 1,46 contre 1,62), des fovéas plus larges et enfoncées, et seulement deux coloris dominants (brun doré, bleu).

ESPECES DU GENRE CARABUS L. DANS LES PRAIRIES ET QUELQUES AGROECOSYSTEMES DU BANAT pag. 411-414

Florin Prunar, Jean Barloy, Ioan Pălăgeşiu, Ioana Grozea

Le Genre Carabus L. est présent au Banat avec 22 espèces parmi lesquelles la plupart sont répandues dans des zones prairiales. Les observations sont faites dans les années 2000- 2006 dans diverses stations avec une analyse de la présence et de l`abondance de ces espèces. L’abondance des espèces dans les captures d`un endroit d`observation est déterminée par rapport à la date de capture, par les conditions climatiques et par les caractéristiques offertes par l`écosystème. L’analyse de ces trois facteurs pour un territoire donné en corrélation avec l`aire de répartition des espèces permet d’expliquer l`absence des carabes dans un écosystème. Les endroits qui ont une diversité élevée d’espèces ont d`habitude des populations aux effectifs réduits ; par contre, ceux où sont présentes à un moment donné seulement une ou deux espèces ont des effectifs élevés.

ANATOMICAL LEAF INVESTIGATIONS ON VARIOUS SUNFLOWER HYBRIDS GROWN UNDER DIFFERENTIATED FERTILIZATION CONDITIONS pag. 435-440

Carmen Doina Jităreanu, Liana Doina Toma, Camelia Ifrim

Various studies pointed out the effect of NPK mineral supply on the biology of sunflower leaf apparatus: form, structure, and activity of photosynthetic apparatus. Investigations have been conducted on five sunflower hybrids (P.I. 2001, Select, P.I. 2002, P.I. 2004, and Performer) with various degrees of precociousness, fertilized with different NPK rates (N 0 P 0 K 0 ; N 60 P 80 K 60 ; N 80 P 80 K 80 ), under pedoclimatic conditions of the Moldavian Plain. Leaf morphogenesis was analysed by determining the number of active leaves and leaf area per plant, as well as the anatomical structure of leaf, at limb and petiole level. The obtained results have demonstrated that leaf morphogenesis was differentiated according to studied hybrid and dose of applied fertilizers. Analyses concerning the anatomical structure of leaf have shown differences between experienced variants, which were found especially at the leading tissue and stomata apparatus. The differences were quantitatively: number of collenchyme layers, number of stomata per area unit, number of leading fascicles, and qualitatively: presence of concentric fascicles, presence of the cap of lignified cells in the phloem parenchyma, and the presence of two stomata types.

The article comprises the investigation of the root, stem and leaf anatomy of a species which frequently grows on the bank arround Thechirghiol Lacke near Constantza county, Sueda salsa (L.) Pall. The anatomical characteristics of Sueda salsa vegetative organs has been described and discussed. The mature root possesses a typical secondary structure. The stem has a primary structure surrounded by the cortex differentiated into a chlorencymatic and parenchymatic tissue. The stem vascular sysem, composed of xylem and phloem, forms a circular ring around the stem. Remarkable is the presence of the inner phloem due to the proliferation of the xylem vessels into the parenchymatous tissue. The stem and blade epidermis is covered by a thick cuticle supplimented by wax. It continuity is interruptured by the presence of paracytic stomata. The homogenous blade has no slat glands or salt bladders, thus, this plant must compartmentalize the toxic excess of Na + , K + şi Ca 2 in the leaf cells vacuoles, increassing the vacuoles concentration, withstanding to the harsh salting condition of its habit.

POSIBILITIES OF VALORIFICATION OF MAIN MACROPHYTIC ALGAL BIOMASS FROM THE ROMANIAN BLACK SEA SHORE pag. 469-472

Daciana Sava, Manuela Diana Samargiu, Gabriela Mihaela Paraschiv

Ocean and marine vegetation is dominated by algae, rocky shores being abundantly covered with macrovegetation that is almost exclusively seaweeds. Although the Black Sea shore is not very long and the conditions of the water are particular compared with other seas, we can find here some species that develop large biomass that make them suitable for harvesting and utilisation in different ways. In this paper we evaluated macroalgal biomass of some common genera of green and red alga (Chlorophyta and Rhodophyta) from our coasts. As the values are quite noticeable it is possible to use this valuable biomass as fertilizing resource, food for animals or as row material source for medicine and pharmacy.

he study on the benthal fauna in Matita and Merhei lakes is based on a number of 172 qualitative and quantitative samples collected in two stages (June and September) from different regions of the two lakes and from different substrates; the processing of the biological samples permitted the identification of a number of 58 species from 18 supraspecific taxonomical groups: Hydrozoa, Spongia, Turbellaria, Nematoda, Nematomorpha, Polychaeta, Oligochaeta, Hirudinea, Gastropoda, Bivalvia, Acarina, Ostracoda, Copepoda, Amphipoda, Cumacea, Mysidacea, Isopoda and Insecta. The invertebrate associations are structured into two major communities: the community of sedimentophile species and that of phytophile species. A relatively low number of species is cited as present in both basins, especially among the sedimentophile ones. However, the phytophile fauna is abundant in Matita, which is explained by the rich submersed vegetation.

ECOLOGICAL STUDY OF VAGILE FAUNA DISTRIBUTION FROM THE BLACK SEA SHALLOW WATER AT VAMA VECHE pag. 499-506

Gabriela Mihaela Paraschiv, Manuela Diana Samargiu, Daciana Sava

This study of the shallow water littoral zone from Vama Veche regards the vagile psammophile and phytophile/iliophile fauna from the midlittoral stratum and superior infralittoral (0 – 2 meters deep) and it is based on 62 quantitative biological samples, taken in July and the first part of October 2005. Representatives from 15 supraspecific taxonomical groups were identified: 44 species in the psammon and 32 species in habitats from the hard substrate with vegetation; a relatively reduced number of species are encountered in both types of habitats, which is owed mostly to their euritropism and capacity to move or to the fact that they are drawn by the water masses; however, most species manifest an accentuated positive tropism for different types of habitat, such as certain species of psammic Turbellaria and Polychaeta: Archilina endostyla, Monocelis lineata, Saccocirrus papillocercus, Namanereis pontica or the species of phytophile crustaceans from the group of Harpacticida and Gammaridae Amphipoda or of Isopoda: Eurydice pontica-psammic, Sphaeroma pulchellum and S. serratum-iliophile, Idotea and Naesa bidentata phytophile. The coarse midlittoral sediments are dominated by species of Turbellaria, Polychaeta, and Harpacticida. Representatives from 13 supraspecific taxonomical groups were encountered in these habitats; representatives from eight supraspecific groups were identified in the mid-fine sediments from the sheltered zones of the infralittoral, the dominant ones being nematodes and species of psammic copepods. A large number of species from 15 groups were identified in the habitats with macro algal vegetation, the most frequent and abundant of them being the Peracarida crustaceans from the group of Isopoda and Amphipoda.

THE DYNAMICS OF PIGMENT CONTENT IN TWO SPECIES OF MARIGOLD (CALENDULA OFFICINALIS L.) pag. 507-510

Alina Elena Marta

The marigold is a very useful species of medicinal plants with many uses in phyto-therapy and cosmetics. The carotenoid pigments in the marigold’s inflorescence represent a fundamental constituent of drugs. The paper examines the dynamics of the pigment content in leaves and inflorescence in two marigold cultivars, the Comun and Bellezza del Pacifico, with yellow and orange flowers, respectively. The pigment content was measured by spectrophotometry. The results point out a maximum carotenoid pigment content with maximum light absorption in 425-426 nm and 447-447nm in the orange flower cultivar (the Bellezza del Pacifico cultivar), which pleads for its introduction into cultivation.

WAYS OF ASSESSING MANAGERIAL EFICIENCY OF REPRODUCTION IN PURE BREED SWINE pag. 511-514

Cornelia Petroman, Ioan Petroman, Horea Sărăndan

Economic success, i.e. obtaining profit on swine farms is influenced by managerial factors that ensure performing standards of reproduction parameters in swine by diminishing service period and by achieving a calving interval between 152-154 days. Obtaining from each sow 2.37-2.40 calvings per year over a longer period of exploitation (6-7 calvings) contributes to the recovery of occasional expenses with the raising of breeding stock until the optimal age for reproduction.

WAYS OF CONDUCTING PUERPERIUM IN SOWS pag. 515-518

Cornelia Petroman, Ioan Petroman, Horea Sărăndan

In the conditions of raising animals on farms with a high degree of artificiality and mechanisation, the evolution of the puerperium influences the increase of the fecundity and birth rate percentage and results in an increase of the duration of exploitation of sows. This evolution depends on the hypothalamus-hypophysis hormonal complex that, during the first post-partum days, secretes gonadotropic hormones that trigger ovary activity. The earlier the ovary activity, the earlier the uterus involution, degradation and eviction of secretions, and the morphological and functional recovery of the endometrium are. Ovary activity in sows in puerperium is characterised by a substantial diminution of the size of yellow gestation bodies during the first 7 post-partum days and the turning of the red colour in the first day into dark brown and, towards the end, into mother-of-pearl white.

DROUGHT EFFECTS UPON PROLINE AND CHLOROPHYLL METABOLISM IN OAT CULTIVARS (AVENA SATIVA L.) pag. 519-524

R. Şumălan, Carmen Dobrei, G. Moşoarcă

Oat (Avena sativa L.) genotypes Chamois (drought tolerant) and Someşan (drought sensitive) were grown in pots in greenhouse under controlled conditions and submitted to drought as follows: V 0 - normally hydrated control variant (0 S); V 1 - 5-day drought (5 S); V 2 - 10-day drought (10 S); V 3 – rehydrated after 10-day drought (10 S – 5 R). The observations and determinations were performed during the phenophases of vegetative mass development upon the following physiological indices:- the osmotic potential of the second leaf (- bar, - the free proline quantity within the foliar apparatus (mg/g.d.w.), - the quantity of chlorophyll pigments (mg./g.d.w.). All these determinations were carried out upon the foliar apparatus belonging to young, mature and senescent leaves competition with the biosynthesis of the chlorophyll pigments. The genotype Chamois (drought tolerant) has an increased capacity of proline biosynthesis in competition with the biosynthesis of the chlorophyll pigments.

SPECIFIC FEATURES OF THE RADICULAR SYSTEM FOR PLUM TREE SPECIES “CENTENAR” CULTIVATED ON THE GROUND BROWN-SCARLET LUVIC pag. 525-530

A. Ciobanu

In this paper are presented some researches concerning depth of the plantation of the roots horizontal of the variety ”Centenar” plum tree, from the plantation created on the Experimental Station Banu Mărăcine. The researches had been achieved in the autumn of the year 2006, at the variety Centenar plum tree, grafted on 4 rootstocks, respectively: Oteşani 8, Pixy, Miroval and Roşior văratec, and the method of study it was used the profile method. We found out that the maximum depth of the horizontal roots development is of 90 cm, the most roots we can found to the 30-60 cm depth. As a result we suggest the depth of working in the orchard to be normal and the incorporation of the organic fertilizers must be realized once with autumn ploughing.

Phaseolus vulgaris has a great variability regarding the tolerance to saline stress, starting with values of 40-46 mM NaCl and up to 196-207 mM NaCl. The experimental results achieved made evident the existence of some bean genotypes with a good tolerance to salinity during germination (Ohaba Forgaci I, Ohaba Forgaci II and Berini). These genotypes have recorded during germination normal intensities of radicle growth and cotyledon development, and they have synthesized important amounts of free proline with osmoprotector role. We have also determined the dynamics of the dry matter percent during germination and within the post-germination phases. The increase of the dry matter percent in the sensitive genotypes is due to their incapacity of hydration and water maintenance.

The reserve is located in the piedmont depression of Mehadia, at the southern terminals of the Semenic Mountains, as part of the large tectonic passage Timiş-Cerna. Though located in the neighbourhood of other nature reserves in southern Banat – the Caraş Gorges, the Gârlişte Gorges, the Nera Gorges, the Miniş Gorges, and the Rudăria Gorges – it has been less studied, and there is no complete presentation of its flora and vegetation of the nature reserve.

THE VARIATION OF QUAN TITATIVE PHYSIOLOGICAL INDEX IN THE TRANSGENIC SOYA CASE CULTIVATED IN DIFFERENTIALLY CONDITIONS pag. 547-552

Silvia Prunar, Renata Şumălan, Isidora Radulov, Lucian Ghinea

The mains physiological indexes which were followed through the present research were: the leaf area at the soya plants as well the determination of azote and phosphorus from the plant. In the conditions in which the plants are treated with differentially nutritional solutions, it is observed that both in the transgenic plants case and in the intransgenic one the leaf surface in higer at the variants with complete nutritional solution than with the solution without azote or without phosphorus, and the quantity of azote, in plants increases in the same conditions. The phosphory from the plants increases both at the plants treated with complete solution and incomplete thanks to the fact that the phosphorus is easily accessible to the plants in the both conditions.

AQUATIC AND PALUDICOLOUS FLORA OF THE NATURE RESERVE PIŞCHIA pag. 557-564

Alina Georgeta Neacşu, Gicu Gabriel Arsene, Alina Margareta Arsene

The flora of the natural reserve Pişchia is very interesting mainly due to the presence of aquatic and paludicolous species. For the moment the synopsis of the flora counts up to 153 cormophite species, belonging to 43 botanic families. The observations were made during the period 2005 – 2006. Together with drawing up the floristic inventory, we have also considered the analysis of the species based on several aspects: categories of bio-forms, geo-elements and ecologic categories.

In the Rudăria Gorges, the water meadow vegetation belongs to the Stellario nemori-Alnetum glutinosae (Kästner 1938) Lohm. 1957 association characteristic to the hill and low mountain areas. The valley characteristics determine the water meadow vegetation to be discontinuous: on the steeper walls over the forest road, water meadow species mix with lilac and flowering ash bushes, while upstream the beech and hornbeam woods go down to the river banks. The vegetal cover contains thermophilous species also characteristic for other gorges in southern Banat. Mediterranean, Balkan, and Pontic elements underline the link between the flora in this area and that of other regions south from Romania. The diversity of flora in the Rudăria Gorges is completed by the presence of some endemic, rare species.

The potato cultivar studied in this paper presents a special economically and alimentary importance, but is recalcitrant to the “in vitro” culture techniques. This fact makes more difficult the obtaining of healthy potato seed material, free of viruses, in a shorter time. Thus it was established an optimum micropropagation protocol for this cultivar, using two different culture media and different hormonal variants.

CHARACTERISTICS OF LABOUR IN THE RURAL AREAS OF SERBIA pag. 583-590

Dragica Božić, Petar Munćan, Natalija Bogdanov

Labour in agriculture may be analysed from the standpoints of economic structure of the population, its household members' structure and employment structure. According to the 1991 and 2002 censuses agricultural labour in Serbia has declined both absolutely and relatively. Based on the share of the agricultural in the total population (10.9%), i.e. the active agricultural in the total active population (15.6%) Serbia has no shortage of agricultural labour. On the other hand, both the age and education structure of agricultural labour are unfavourable raising the issue of self-reproduction. In addition, the number of household members especially individual farmers representing the key labour in agriculture, has been significantly reduced.

MISLEADING COMBINING FORMS: HYDR(O)- pag. 591-594

Anica Perković, Georgeta Raţă

The purpose of this study is to help students in chemistry and in any other field related to chemistry differentiate, better understand and use more properly the terms beginning with hydr(o)- , terms that can be misleading because of their different referent (‘hydrogen’, ‘water’, and ‘hydrargyrum’). In our attempt, we have used the lexicological approach. We have found out that there are about 84% combined words with hydr(o)- (‘hydrogen’) and hydroxy(l)- . There were no limitations to this study. The practical implication of the study is that all these combined words make up an exhaustive inventory which, if properly acquired by the students, can help them decipher more easily the meaning of any specialised text in English.

NOTES ON TOURISM TERMINOLOGY IN THE NEW ZEALAND ENGLISH pag. 595-598

Anica Perković, Georgeta Raţă

The purpose of the study is to show if there are any differences between the British English of tourism and the New Zealand English from a globalising perspective. The study was carried out on a relatively small corpus of tourism terms (91), which we analysed from a lexicographical point of view. The study shows that most of these terms are acronyms, probably due to the speed people need to communicate nowadays. The study was limited by the fact that most of the tourism terms analysed cannot be found in English Language dictionaries. The practical implications of the study concern students in tourism economics: thus, they can get aware of the fact that though the English language spoken in New Zealand may seem identical to that spoken in Great Britain, the English of tourism may be considerably different. The originality of the paper consists in the fact that this is the first time such an inventory is being analysed in the Balkans.

SLOVAK REPUBLIC POTENTIAL AND SUITABILITY FOR TOURISM WITH EMPHASIS ON AGRITOURISM pag. 599-604

Pavol Otepka, Miroslav Habán

The whole tourism industry, including agritourism, is growing rapidly worldwide. Slovakia, regarding its geographic location in the centre of Europe, has extremely favourable conditions for rural tourism, especially for agritourism. Beside the natural richness, such as mountains, caves, water areas, mineral waters, springs with healing effects, rich fauna and flora, also historical buildings, held in relatively good state, and many live traditional crafts can attract the modern tourists. Regarding all this, Slovakia is able to satisfy the needs of the most demanding our or foreign tourists. The main objective of this work is to briefly present the natural beauties and cultural attractions in Slovakia, its favourable conditions and development possibilities in the agritourism sector. Furthermore there are described the tasks and activities of organizations responsible for agritourism and rural tourism (EUROGITES in Europe, SARTA in Slovakia).

Limitation of resources and its rational utilization represents the main obstacles to development of households. This paper emphasizes the luck of labour force and its unsatisfactory qualification structure, with which, under given circumstances, managers have to achieve as good results as it is possible. To get closer to that goal, the labour force managing process should start with labour force selection and evaluation of its work. The best results have been achieved with combination of scientific methods, long – term personnel planning, objective evaluation of the work and inclusion of the workers in evaluation process. The goal of all the methods is to identify the bed and the good sides of the workers, to propose how to dispose the bed and how to improve the good sides and that way to increase the labour productivity.

EFFICIENCY EVALUATION OF BUSINESS PLANS IN PLANT PRODUCTION pag. 611-616

Z. Rajić, Ivana Ljubanović-Ralević, Nebojša Ralević, Dragana Đurić

Decision making about investment acceptance is always based on the intention of the investor to gain certain income during the investment period. The integral analysis of economic effectiveness of investment is based on the analysis of economic success, liquidity, and risk, as a three basic components of investment process. Unfavourable financing conditions require from the owner of the household to make plans for lucrative businesses. This kind of planning considers formulation of expectations in the future, especially the relations between inputs and outputs, products prices and production costs. In crop production planning the rule of the highest revenue on limited resources should be applied. Before formulating alternative plans in crop production, special attention should be paid to intensity of soil usage. The selection of production lines depends on the most productive and the most lucrative crop system.

THE ROMANTIC DIALOGUE WITH THE BIBLE IN ANTON STRASHIMIROV’S POEM “SONG OF SONGS” pag. 627-630

Velislava Doneva

With his undoubtedly restless and inquisitive creativity, in the first decade of the twentieth century, Anton Strashimirov turned to the modern European drama, eagerly expecting the new century, and with it - the new man. He created dramas full of symbolism, most of which remain only as marginal texts for the Bulgarian reader. In some of them aspiration for interpretation of Biblical topics and motifs is revealed. A dialogue with the Bible can be traced in other dramatic works of his, outside the context of symbolism. One of them is the romantic “Song of Songs” (1910). Strashimirov is one of the Bulgarian authors, who chooses consciously, as an artist, and not sporadically, as a dilettante, the creative realization of biblical and mythological constructs for the Bulgarian drama.

BUSINESS RISK AND UNCERTAINTY OF INVESTMENTS IN THE GRAPE PRODUCTION pag. 637-641

Branka Kalanović, Zorica Vasiljević, B. Dimitrijević, Snežana Trmčić

Biological character of grape production influences the existence of numerous risks. Therefore, the research on risk and uncertainty is one of the key problems of the investments into this kind of production. These risks are appearing both during the vineyard establishment and during its exploitation and they are influenced by the state of soil, application of agrotechnical and pomotechnical measures, diseases and pests appearance, the way of yields realization as well as the market risks. Perception of risk is a precondition for business success and the higher profit realization. This is the reason why risk management (identification, analysis and monitoring) should be a part of management policy. One of the methods for the risk and uncertainty assessment in the case of the grape production investments is the sensitivity analysis method. This method could show to investor how much the investment effectiveness indicators are sensitive onto the possible changes of variable starting parameters (prices, production volume, expenditures, level of investments etc.), i.e. this method enables constitution of the so-called certainty limits of particular starting parameters, which are considered as critical ones in the investment effectiveness evaluation. By application of the sensitivity analysis method in the case of two analyzed economic models of vineyard farms, it has been monitored development of the investment effectiveness indicators in relation to the changes of starting parameters and there have been determined their certainty limits.

Viticulture production is highly intensive production which demands both human work and considerable capital to be fertilized through various activities. In Serbia this type of production is organized on small family estates as well as plantations. Although there are all conditions of successful grape-vine growing in Serbia, economic researches show that viticulture production, in spite of the capacity available, is not on expected level.

ON THE IMAGE OF THE CITY OF TIMIŞOARA AND OF THE BANAT AREA IN THE 15TH AND 17TH CENTURIES pag. 647-650

Ioan Petroman, Snježana Tolić, Cornelia Petroman, Ioan L. Caba

Though medieval descriptions of Timişoara are scarce – the most consistent of all being that of the Ottoman traveller Evlyia Celebi and of the Austrian traveller Henrik Ottendorf – the reconstitution of the epoch, i.e. of the features of a medieval town and city, can only rely on extremely diverse information. The lack of documents that describe directly and without any exaggeration aspects of life, corroborated with a very large number of indirect evidence can result in a proper, edifying global image on the ground of an engraving and of a map of the streets of medieval Timişoara that are unique in the historiography of this town. The general engraving of Timişoara, published in the revue Magazin istoric by the Romanian Ioan Haţegan, confirms the information supplied by Henrik Ottendorf which, confronted with those supplied by Evlyia Celebi and with the drawing made by the Austrian F. Watthay, coincide. In addition, it is confirmed that in the middle Ages the name of the river flowing through the ditches of the city was the Timişul Mic. A problem that could be confusing in Henrik Ottendorf’s description is that of the location of the Castle, which he locates south from the city, not in the narrowest part of the fortification, but right in the middle of it.

The most numerous documents concerning the history of the Banat area are written in both European languages and Turkish. They were written at the end of the 14 th century, before and after the Ottoman conquest. The name of the capital of the Banat area, Timişoara, is mentioned in the Chronicle by Asikpasazade in 1484, where it is written that the Turks passed by Demeskar (the spelling ‘d’ is due to the Turkish pronunciation of the Hungarian name “Temesvár” meaning ‘Timişoara’), went on and entered the Hungarian Country. After the Turks left the area, a vast programme of colonisation of the Banat area with Italians and Spaniards original from Austrian-ruled provinces was put into practice (1716-1740).

In this paper we analyse, on the ground of a research on an experimental group of 30 children aged 6-7 and enrolled in Preparatory groups A, B, and C of the Kindergarten No. 23 in Timişoara (România) the cognitive mathematical behaviour shaped while attending kindergarten, as a premise for future assimilation. In order to study the level of development of the children’s mathematical abilities and skills – counting, making up multitudes, additioning and subtracting, and identifying geometrical shapes – we applied six written tests, recording the score for each child and assessing each child’s activity. Analysing test results, we could see that some of the tested children that encountered difficulties made mistakes because of lack of attention, while the other ones need supplementary work from the teacher, the choice of the most efficient methods to make understanding easy and to make children properly learn the mathematical elements necessary in the 1 st grade.

In this paper we analyse a few aspects concerning moral and civic education as an important aspect of education in general, on the ground of 9 th and 10 th form students’ opinion; we are also interested to see in what measure educational classes reach or not moral and civic objectives and if the topics are of particular interest to students, and if the teacher uses means and methods that are active and formative. Synthesising drawbacks during educational classes, we suggest both form masters and school managers to pay more attention to educational classes topics and issues. In order to shape beliefs and features of character, teachers should start from this in their approach of students’ problems, i.e. better know each student apart and direct and satisfy his/her wishes and aspirations. Among the features required from a good form master are besides the features of a good teacher in general, the sympathy for the students, positive traits of character (sincerity, communicativeness , etc.) and especially to be a good teacher that uses proper methods and means to teach.

DEVELOPING A GENERALISED INPUT-OUTPUT MODEL FOR THE VALORISING OF A TOURISM SITE POTENTIAL pag. 679-682

Ioan L. Caba, M. Glevitzky

In this paper, we aim at identifying the methods of determining the models of the influence of variations of some parameters on the “tourism process” and of its definition. The system in general can be described by proper modelling. The necessity for developing such a system model in the case of solving an optimisation problem results from the fact that its expression depends on the variables of the system. The generalised interpretation analysis of the tourism process leads to the development of a generalised model of inputs-outputs for the determination of the functional links existing between the different variables in order to establish functional dependence relationships. Applying the models, even if generally, can result in considerable improvements in increasing performance, in deepening knowledge, and understanding the ensemble in general.

INFIDEL BEHAVIOUR: INVOLVED PERSONALITY pag. 727-732

Codruţa Gavrilă, Maria Palicica, Viorica Coteanu, Mădălina Creţu

The study presents the analysis of infidelity, its causes and effects on the marital relationship; we capture those traits of personality that make a person become infidel. To do so, we take into account both the consequences of infidelity and the feelings the hurt person experiences, such as uncertainty and confusion. The total number of the subjects of this study is 80, of which 40 women and 40 men. The subjects we tested, aged 20-25 and 35-50, were selected taking into account the way they got married; we only tested one partner of each couple. Thus, of the 40 women, 20 are aged 20-25, while the other 20 are aged 35-50. The structure of the male sample was identical. There are, in the sample of men and women aged 20-25, 10 people from undergraduate families attending the course, of the Agricultural and Veterinary University of the Banat, Timişoara. After making a synthesis of the theoretical aspects, we can say that both men and women tend to become infidel. The reasons for infidelity are: the tension within the couple, indifference, ignoring the other’s wishes and desires, limiting to unpleasant talks detrimental to humorous ones, etc. Infidelity has always important consequences – sometimes even capital ones – for the infidel himself or herself, for his/her partner, and for his/her group. Such a situation shakes self-confidence and makes everybody ask himself or herself questions.

The study aims at emphasising the necessity of knowing temperamental features of the human factor directly involved in the educational process: student and teacher. Their use in the educational process results in an increase of efficiency. The educational process is by excellence the result of the interaction between teacher and student, student and student, etc. Both education and training depend on the existence of a positive inter-relationship, of an efficient partnership. Though is relies on the nervous system features, and hereditarily determined, in biological terms temper is considered a pheno-typical result; temper features have nothing to do with fatality, they can be changed through activity, education, and self-education. In order to carry out the study, we used the temper typologies described in literature, psychological questionnaires meant to determine the temper type, and psychological experiment. The research opens a perspective on the size of the temper features impact on the educational process and on its efficiency. The results of this study can be a theoretical aid for the teachers in practical activities with the students and, at the same time, a milestone in self-regulation.

MOULDING ECOLOGICAL AWARENESS IN SCHOOL pag. 739-742

Viorica Coteanu, Maria Palicica, Codruţa Gavrilă

Ecological education is a form of education, which, through a system of specific activities, ensures the moulding of ecological awareness. Moulding ecological awareness in school has two main components: a cognitive one and an affective one. There have to be a good cooperation between topics in school so that each of them aids in moulding ecological awareness in children. Bringing man to the verge of respecting nature and landscape values can be done through instruction and education. Ecological education aims at guiding the student, i.e. the future citizen, to a more objective point of view over reality (whose fundament is the relationship between man – men – environment), to enhance him to participate, to become aware of the future, of the fact that the life of future generations and its quality largely depend on his options. At present, it is necessary to study ecology at school, with a view to teach the young ones – anybody else, in its debut stage –on why and how to protect nature. It is necessary that ecological education be an important part of school education and instruction.
