PROCESSING AND INTERPRETATION OF SATELLITE IMAGES – LANDSAT pag. 3-9

Bianca Balulescu, Buresin Marica, Tecar Loredana, Mihai Herbei*

Abstract : The Geographic Information System is a collection of located, collected, stored and managed geographic data with the use of the computer, data which can be used to perform various spatial analyses. The special GIS operations over the spatial information make from these instruments more than just efficacy instruments for making maps, but especially, irreplaceable instruments for analyzing the information that refer to the terrestrial surfaces. GIS maps must be made exploiting all available resources based on rigorous analysis of their content and the costs involved, seeking assurance required with maximum efficiency. The information obtained from remote sensing is contained by the cosmic or aerial images, which can be interpreted for many purposes. Building these images is based on detection and registering of electromagnetic energy reflected or issued by the surface of the objects present on the visual field of the sensors, which interacted with the electromagnetic energy issued by a natural source (e.g. Sun, Moon) or an artificial one (e.g. radar). The response of the objects from nature to various wavelengths of electromagnetic radiation is different, depending on their physical and chemical properties, configuration and surface roughness, its illumination intensity and angle of incidence. These responses recorded via sensors translate the image by the emergence of patterns (features), based on which objects can be distinguished and identified. The remote sensing data is public, meaning it can be acquired from any area of the world and by anyone, with some restriction. The images used in this study were taken from Landsat 8 satellites.Landsat 8 consists of three key mission and science objectives:Collect and archive medium resolution (30-meter spatial resolution) multispectral image data affording seasonal coverage of the global landmasses for a period of no less than 5 years;Ensure that Landsat 8 data are sufficiently consistent with data from the earlier Landsat missions in terms of acquisition geometry, calibration, coverage characteristics, spectral characteristics, output product quality, and data availability to permit studies of landcover and land-use change over time;Distribute Landsat 8 data products to the general public on a nondiscriminatory basis at no cost to the user.

COPPER MINING WASTE, A SOURCE OF OLIGOELEMENTS FOR AGRICULTURE pag. 10-13

Bogdan BORCEAN Lecturer ing. Lucian BOTOŞ, PHD

The examined material is the mining waste resulted from the banatite mining exploitations in South -Western Romania – Sasca Montană – Moldova Nouă region. This waste material contains important amounts of microelements (manganese, cobalt, boron, molybdenum, copper, zinc and others) and macro-elements (phosphorus, calcium, magnesium, sulphur). At the moment, the material is deposited in waste dumps of thousands of tones. It results of this paper that this mining waste contains mainly compounds of silicon (31.89%) and calcium (13.13%), followed by iron (5.32%) and aluminium oxides (1.25%) and sulphur (1.42%). The content of oligoelements found in the samples analyzed by I.C.I.M. Bucharest varies as follows: Copper 0.08 -0.1%, magnesium 1.7 – 2.4%, molybdenum 0.004 – 0.005%, zinc 0.02 – 0.07% and others. The graded composition of the material in the mining waste is: gravel 10%, coarse gravel 25%. The researches regarding the use of this material in agriculture were carried out on the territory of Sasca Montană, a region where the average annual temperature is of 11.5 °C according to the Meteorological Station Oraviţa and the annual precipitations are of 680 mm. The area belongs to the moderate temperate continental climate of Banat sub-type with submediterranean nuances. The mining waste was analysed on two cultures, maize and triticale. The soil type is a stagnic preluvosoil, having a poor acid reaction of between 0 – 160 cm (pH-5.71), with a moderate humus reserve. The effect of using 1 tone mining waste under the conditions of a differentiated fertilization with N0P50K50, N60P50K50, N120P50K50 and N180P50K50 was studied for both crops. The average increase in crop registered for the fertilization levels due to the use of mining waste was of 30% for triticale and of 22% for maize grains. The nitrogen fertilizers were well used by both cultures, both on a mining waste basis, and on a basis without mining waste. The average triticale crop for the two cultivation variants increased with 44% for the variant fertilized with N60, with 87% for the variant fertilized with N120 and with 118% for the variant fertilized with N180, under the conditions of a uniform fertilization with P50K50 For maize the crop increase when fertilized with nitrogen was of 56% for the variant fertilized with N60, of 90% for the variant fertilized with N120 and of 121% for the variant fertilized with N180.. The fertilizers were better used on a base of mine waste, because of the calcium contained in the material which partially neutralized the soil acidity.

PRODUCTION POTENTIAL OF GRAIN SORGHUM (SORGHUM B.VAR. EUROSORGHUM) UNDER THE INFLUENCE OF FERTILIZATION AND HYBRIDS STUDIED pag. 30-33

Dacian Coclea, Simona Niţă, Ioana Maria Mateaş

Abstract: History shows that cereals have always maintained their significance, along the development of human society and to this day. In addition, however, one can see a close link between grain production and progress of civilization. Sorghum is a very old culture, known in India for over 2000 years, cultivated for: beans, brooms, rich in sugar syrup, animal feed or fodder crop as green. Climate Change to heating and unproductive during 2001-2050 in the Balkans, which is located and Romania, requires a reconsideration of sorghum as: cereal food (beans composite flour used in the formula for baking gluten and gluten-free, fresh juice, extracted of strains used in the manufacture of syrup, vinegar and other food), fodder (as green mass, hay storage, feed pellets) and crops (sorghum and sorghum mature mellitus for the production of raw materials for energy (liquid, solid, gas, electricity, heat), chemical (stationery and textile pulp, plastics), building materials and craft industry (of household and industrial brushes, brooms, blended. Sorghum is the second cereal after maize commercially exploiting the heterosis effect in the agricultural farm, which increased the average production per hectare. is the first grain sorghum that has been fully sequenced genome (2006), which will give rhythms in November progress in improving the species in the coming years. sorghum grains used directly in the form of flour feeding people in some parts of Africa, India, China, Middle East and Egypt. In industry is used in the manufacture of starch, alcohol and beer, mixed with grains of barley. The sweet sorghum juice is extracted a sweet, rich and varied sucrose fitom energy use. In many parts of the world sorghum was traditionally used in various foods such as porridge, unleavened bread, cookies, cakes, couscous and various soft drinks and alcoholic. Sorghum has unique properties that make it very suitable for food use. Some varieties of sorghum are rich in antioxidants and all varieties of sorghum are without gluten, an alternative attractive for those suffering from wheat allergy. Modern science in food and nutrition, attaches great importance to the role of nutrition in prevention of onset. Special attention is given to the development of food products for people with increased sensitivity to certain foods. The culture of sorghum, using far fewer pesticides than other crops (wheat and corn). It also should not neglect the fact that sorghum, sorghum particularly diabetes, contribute significantly to reduce air pollution bad. In different literature, shows that one hectare of sweet sorghum absorbs from the atmosphere each year between 40 and 55 tones of carbon dioxide (CO2), while other crops, eg cereals, only 3 to 10 tons per year CO2/ha . It should be noted that the sorghum plant is not lost anything after processing. Experience is bifactorial type, so that the annual Repeat the cycle terminates the experimental field we have experience in first year, second year and third year. The biological matherial used were hybrids F32 and Arakan. F32 hybrid obtained from INCDA Fundulea, the seed being certificate, and hybrid Arakan French provenance. Mineral fertilizers applied to grain sorghum crop, increased grain production. Variation in grain production in grain sorghum grain (Sorghum b. var.

Mihai Teopent CORCHEŞ, Alina LAŢO, Karel LAŢO

Exploitation of mineral aggregates as sedimentary type has a great expansion at national level and at the level of the Alba Iulia County; due to growing industrialization thus aggregate resources are critical to modern society. Aggregated resources are used in almost every element of the newly built environment, whether for roads, bridges and transportation infrastructure, either for private development. Natural aggregate (crushed stone, sand, and gravel) is used as a construction material in various sectors, especially in this period, when, in Alba County, are developing a series of infrastructure projects, such as the construction of highways and railways. Sand and gravel pits are located in almost every city of Alba County, especially on the terrace of the rivers Mures, Tarnava and Sebes. In this period the demand for aggregate will continue to grow, due to the increasing number of infrastructure projects in the coming years. Investments in transport infrastructure that were started in the city of Sebes require a large amounts of mineral aggregates, therefore deemed appropriate location of that exploitation of mineral aggregates in the locality Lancram, area rich in resources, in order to secure the raw materials necessary, but also to reduce their transport costs from other areas. The present work want to be a study conducted for the identification and quantification of soil and groundwater impacts generated by the exploitation of mineral aggregates from the upper terrace of the rivers Mures in Sebes municipality area.

ASPECTS REGARDING THE CAUSES AND CONSEQUENCES OF VIOLENCE IN SCHOOL pag. 68-73

Codruţa GAVRILĂ, Viorica COTEANU

In this paper, the authors analyse a few aspects concerning violence in school which is, from a statistic point of view, the most frequent deviant behaviour in school. The different forms of violence among schoolchildren occur in different contexts. Breaks between classes mean a space where schoolchildren are not watched by their teachers, which allows them to inter-relate. Knocking, offending, pushing, wounding, hurting, cursing, threatening, and vandalising are but some forms of the violence in school. The conclusions the authors have reached thanks to a questionnaire applied to secondary school pupils allowed the former to develop a few directions of prevention and solution of school violence, a phenomenon that has marked the health state, body integrity and psychological development in schoolchildren.

TOPOGRAPHIC SURVEY OF THE SPORTS GROUNDS AND DORMITORIES OF THE BUASVM TIMISOARA, ROMANIA pag. 74-82

Ioana Mihaela Gurgu, Adrian Smuleac

This paper presents the topographic survey of an area within the campus of the Banat’s “King Michael I of Romania” University of Agricultural Science and Veterinary Medicine of Timisoara, Romania, an area that covers the sports grounds and the dormitories. To do so, we used the concept of routing supported on both ends by coordinate points and known orientations that suppose a multiplication of the geodesic network to determine the coordinates of the detail points in the field. The multiplication of the geodesic network was done by determining the coordinates of some points of the order V that became the main elements of the topographic survey. This is why determining them should rely on a very accurate measurement. The topographic survey was done with special topographic instruments: an electronic instrument for the measurement of distances and a Leica TC805 total station. The total station is an optical instrument, a combination between a classical theodolite and an electronic device for the measurement of distances. The coordinates of the control points were determined with GPS equipment, which offers a quick control of static measurements. Data collected by the total station were downloaded with Leica GeoOffice Combined software and compensated through the TopoSys software. TopoSys calculates and compensates any combination of measurement of distances and angles to determine the best correction of the point coordinates. The coordinate processing method allows precision up to an order of centimetres. The coordinates of the compensated points were reported in the AutoCad with a TopoLT programme that operates on the AutoCad platform. This paper is important because presents a situation plan of the area described above in order to identify details; the plan will be used in future works for different goals within the university.

Abstract:Surface modeling is the process of plotting a natural or artificial surface through one or more mathematical equations. Modeling land surface modeling is a particular case of the areas that need to be taken of the specific issues related to the representation of the earth or parts of it. Digital model of an object or phenomenon, consists of a collection of data stored systematically (database) describing a three-dimensional coordinate system, arbitrary or particular characteristics of the object or form their states / achievements phenomenon (conversion as digital image) and allow adequate computer programs deduction form and characteristics of the object or phenomenon achievements Star new points. Digital model of the terrain is a "tool" information consisting of field data and software is a key component of a GIS. DEM consists of an ordered set of planimetric position information and share the points that describe the spatial configuration of the structures carrying relief and reconstruction surface facilitates their new points. Development of a digital terrain model and its future use involves the following steps 1. DTM GENERATION consisting of initial data acquisition and digital model building. This step represents a fundamental stage because the existence of errors introduced during data acquisition will be found in the DTM and will jeopardize the whole process of spatial analysis. Generating digital terrain model refers to the data acquisition module, the actual realization of the model by different interpolation methods and the choice of data structure representation (raster or TIN). 2. HANDLING DTM: correction of errors and possibly update the model, filtering operations, combining multiple sources or models from different periods, the transformation model structure (TIN - raster and vice versa); 3. INTERPRETATION DTM: analysis model and extracting useful information;April. 4. VIEW DTM: DTM graphical rendering (representations2D, 3D, animation, etc..), Closely related to the previous stage; May. 5. OPERATION DTM: developing specific applications for the desired range.

WEB CADGEN application is a part of the informational tools package for data migration from General Cadastral in the system integrated by Cadastre and Real Estate Register. General Cadastral is the unitary and mandatory system of technical, economic and legal records of real estate throughout the country. A Cadastral survey is a project developed on a certain period of time, and has as a purpose collection, approval, correlation, aggregation and delivery to the beneficiary of his own technical and legal data of General Cadastral record. The realization of cadastre is not only a mapping of real estate but also actual determination of property right and collection of the data necessary for property and possession rights certificate. The process needs a permanent interaction with citizens both at their residence and in the field. During cadastral surveys the contractor will retrieve information of a legal nature that take in the account identification of all real estate owners and registration of property right in real estate register, based on transfer, constitutive or declaratory deeds, as well as documents that provide possession. The owner is the legal part that contracted service realization from general cadastral survey; in the current situation, the owner of general cadastral surveys is ANCPI. The supplier is the legal part that provides general cadastral survey service realization, performing measurements, data collection, approval and correlating to deliver them to the owner a full cadastral data package on the contracted area. The supplier can retrieve from eTerra database all the information corresponding to an UAT, to a set of selected properties, etc. for which he will prepare the general cadastral survey. He will process in his own production system the extracted data and the rest of information gathered from the field, etc. and will generate a new actualized data set.

STUDIES CONCERNING THE POLLUTION DEGREE OF GROUNDWATER, IN CARNECEA, CARAS SEVERIN COUNTY pag. 113-118

Anca LOGHIN*, Alin ACHIM*, Adina BERBECEA*

Groundwater represented all the time is of vital importance .Groundwater is an important source of drinking water. Most of the population uses groundwater supply and agricultural purposes. The first wells for drinking water were excavated in Egypt and ancient China. Marcus Vitruvius is the first who observed that a source of groundwater is infiltrating rainwater or melted snow; He is basically the precursor infiltration theory. The first hydrogeological work in Romania is that of Pop V, which refers to the Transilvanian mineral waters. Unfortunately, many of the Romanian wells are already polluted with nitrates and other industrial and agricultural chemicals. Later, Drăghiceanu and Cucu-Starolescu have addressed the issue of groundwater in the area of Bucharest. In this paper we present the results of groundwater chemical analysis, from Carnecea, Caras Severin in order to establish the pollution degree. The main source of pollution in this area , is represented by agricultural and human activities. Analyses of parameters of water quality were made according to standardized methods. The parameters analyzed were pH, concentration of nitrates (NO3-), ammonia (NH4+), nitrites (NO2-), phosphates (PO43-) and chemical oxygen demand (COD. The analyses were performed in the laboratory of Environmental Chemistry of the Faculty of Agriculture, BUASVM King Michael I, Timisoara. pH was determinate by conductometric method; The content of nitrates, nitrites, ammonia and phosphates, was determined by UV-VIS spectrophotometric method, at λ = 520 nm, 410nm, 425 nm, respectively, 715nm.; chemical oxygen demand was determined by volumetric method.

BEHAVIOUR OF SOME MAIZE HYBRIDS IN THE SOIL AND CLIMATE CONDITIONS OF SCDA LOVRIN pag. 119-125

Ioan MACRA, Georgeta POP

In this study, we aimed at testing four early grain maize hybrids – Severo (FAO270), Kinemas (FAO350), Kornelius (FAO400) and KWS 3381 (FAO450) sowed at two consequent times to define their behaviour in the Banat’s Plain conditions, the SCDA Lovrin area, and determine their production potential. The bifactorial trial was set in the experimental field after the subdivided plot method. The experimental field covers 768.4 m2 and the four hybrids were sowed on six 8-m long lines with three replicas. The area cultivated with a hybrid measured 33.6 m2. We sowed 5-7 cm deep in the soil. The sowing density was 60,000-65,000 harvestable plants per ha, and the row distance was 70 cm. For fertilisation, we used a complex 20:20:0 fertiliser, and we controlled the weeds mechanically, manually and using the herbicides Mustang – 0.5 l/ha and Gat Motion – 1.5 l/ha. During vegetation, we made observations in different pheno-phases – sprouting, blooming, silking, physiological maturation – and we correlated them with the soil and climate conditions. Sowing early maize hybrids in the third decade of April ensures temperatures above 100C and the necessary humidity for germination, resulting in high grain yields (STAS 6739 kg/ha) compared to sowing in the first decade of May (6642 kg/ha). The studied hybrids have a good tolerance to drought and heat, and the grain yields reached Severo 5968 kg/ha, Kinemas 6137 kg/ha, Kornelius 7154 kg/ha, with the most productive hybrid KWS 3381 with 7708 kg/ha. Upon harvesting, mean moisture of grain maize was 8.2-12.0%.

RESEARCH REGARDING THE EFFECT OF POLLUTION FACTORS ON SOME TRITICALE CULTIVARS IN THE ROVINARI AREA – GORJ COUNTY pag. 126-133

gheorghe matei

Triticale - that is an specific plant of temperate climates and cold conditions, but at the same time supports easily an culture in areas with warm and dry climate. The specific areas in which culture can enter generalize triticale in culture are areas containing large tracts of land with low natural fertility, that wheat, rye, barley, oats or other grains give lower yields, areas that meet common difficult soils, such as soils with high toxicity of Al, Pb, Cd and Zn to prevent the development of appropriate production of wheat (Angelova V., Ivanov K., 2008). Some trace elements are dangerous because they tend to bioaccumulation in food chain. Bioaccumulation means an increase in the concentration of a chemical in a biological organism over time, compared to the chemical's concentration in the environment. This study want to put in the light the behavior of triticale crop in the conditions of cultivation in the area near the Energetically Complex Rovinari and under the influence of pollution factors from this part of industry.

CHANGES IN SOIL POTASSIUM CONTENT AFTER MINERAL FERTILIZATION pag. 134-139

Iulia Nanu, Isidora Radulov, Andreea Tița (căs. Golea)

Potassium is one of essential macronutrients for plant nutrition. Of the primary plants nutrients, the potassium is known regarding to its influence on the production in general and in particular on the quality of the harvest. To achieve high and good quality yields, potassium fertilization is a factor of utmost importance. Unfortunately in agriculture are used large quantities of nitrogen at the expense of potassium, causing an imbalance because the amount of potassium that is extracted with the yield is much higher than the one that is returned to the soil as fertilizer. This draws decreased soil fertility in terms of a reduced nutrient content. From field experiment soil samples were taken by depth of 0-20 cm for testing. Analysis were made in Soil Science Laboratory of Agricultural Faculty. Potassium was extract in ammonium acetat –lactat solution, and content determination was made by emission with atomic absorption spectrophotometer Varian 220 FAAS, at wave length of 766 nm. pH was determined in water extract 1:2.5. Ammonia is extracted from the soil with a solution of potassium sulphate (K2SO4) 0,1n, soil solution ratio being 1:3 and it is been colorimetrical dosed with Nessler's reagent. Potassium availability for plants is governed by the transfer between four main pools in the soil: native, fixed, exchangeable and soluble. The main contributors to K supply to plants are exchangeable and soluble forms. When K+ is removed from the solution by plant uptake or leaching, the soil solution is rapidly replenished by K+ from exchangeable sites, whereas the fixed clay replenishes the exchangeable sites slowly by a diffusion controlled process. Usually average values of state insurance of assimilable potassium in the arable layer of chernozem cambic, are between 150-200 ppm, which corresponds to a medium and good insurance in this macroelement. There is a reduction in the potassium content of the soil at low pH values. As the pH is close to the neutral values, soil content of assimilable K increases.

STUDY OF DRY MATTER ACCUMULATION ON SIMPLE HYBRIDS IN CYCLIC CROSS SYSTEM pag. 140-144

Andreea ONA1, I. HAȘ1,2, Rodica POP1, Voichița HAȘ2

Dry matter accumulation in grains at the harvesting time is one of the most faithful indicators of the growing season of maize. The paper presents the obtained results of the dry matter accumulation in maize, in the experiments fields conducted at Agricultural Research and Development Station Turda, using simple hybrids in a cyclic cross system, between 2011-2012. The goal of this paper is to identify some inbred lines that are sending a rapid dry matter accumulation in grains at the harvest time and to highlight the genic effects involved in this process. At the harvesting time, for each studied plot was determined grain moisture using GRANOMAT device. Analysis of variance for dry matter content in grains at the harvesting time indicates statistically highly significant differences between variants. Differences occurred also between experimental simple hybrids and the three control hybrids (Turda 201, Turda Favorit and PR39 D81). The effects values for the general combining capacity ranged between -0,75% and +1,43% dry matter at the inbred lines and between -0,79% and +0,72% dry matter at the testers. The effects values for the specific combining ability ranged from -0,77% to 1,07% dry matter. Among the testers inbred lines, the highest dry matter accumulation in maize grains at harvesting time, was sent by the inbred line TC 399 (80,77%); additive genic effects for this value were 0,72%, statistically significant. Among the tested inbred lines, the highest dry matter accumulation in maize grains was recorded by TE 229 (81,48%), the earliest inbred line from the experimental system. Compared with the average of experimental system, there was +1,43% in the general combining ability effects. The highest values for non-additive genic effects were recorded for hybrid combination TE 317 x TC 385A (+1,07%), followed by TE 335 x TC 399 (+0,84%). The heredity of the maize growing season involves additive gene action, but also non-additive interactions. There is a dominance of the early parental forms, simple hybrids being earlier than the parental forms. Our results indicate relatively equal influence of additive and non-additive genic effects for the determinism of dry matter accumulation in maize grains at the harvesting time.

STUDY OF YIELD POTENTIAL OF MAIZE SIMPLE HYBRIDS IN CYCLIC CROSS SYSTEM pag. 145-150

Andreea ONA1, I. HAȘ1,2, Voichița HAȘ2, Rodica POP1

Maize has an important role in the Romanian agriculture, as a result of its multiple uses and optimal conditions from our country. According to the National Institute of Statistics, in the year 2011, the area cultivated with maize in Romania was of 2.613.500 hectares, with a total production of 11.666.400 tonnes of grains, placing our country on the 1st place in the European Union for the area cultivated with maize and the 2nd place for production, after France, due to an inferior yield. Otherwise, the maize yield achieved by Romania is smaller than the one achieved by the other Member States, with only 4464 kg/ha grains beside the average from the European Union of 6902 kg/ha. Yield potential can be considered genetically, the most complex characteristic. We can appreciate that the heredity of this trait is the expression of the entire genetic system of the plant, which directly or indirectly controls all fundamental involved processes (metabolic, growth and development). This paper presents the obtained results of the maize experiments fields conducted at Agricultural Research and Development Station Turda, using simple hybrids in cyclic cross system, between 2011-2012. The objectives of this paper are to highlight the genic effects involved in the heredity of the production capacity at the hybrids derived from crossings of inbred lines resulted by inbreeding, from commercial hybrids, with inbred testers, from Lancaster heterotic group. The analysis of variance for grain yield indicates significant differences between the tested maize hybrids. Comparing the general combining ability of the tested lines, reveals significant differences, the tester inbred lines being from the Lancaster germplasm group and the tested inbred lines from other heterotic groups. Also, were highlighted the effects of the specific combining ability. The effects values for the general combining ability (GCA) of the testers ranged from -85 kg/ha to +143 kg/ha. At the tested inbred lines, the value ranged between -508 kg/ha and +1141 kg/ha. The effects for the specific combining ability (SCA) was between -669 kg/ha and +589 kg/ha. Between inbred lines used as testers, production differences are not statistically significant. Among the tested inbred lines, the highest achieved average production in crosses with three testers, conducted to TA 452. The average yield was 9550 kg/ha and the additive effects for this line production capacity were, for this experimental system, of 1141 kg/ha. Regarding to the inbred lines obtained from Raissa hybrid, the highest production capacity from this experimental system was transmitted by TE 317. Our results highlight that in the production potential heredity are involved, mainly, the additive genic effects, but the non-additive genic effects are also important.

COMPARATIVE STUDY OF B12 VITAMIN DISTRIBUTION AND ASSIMILATION pag. 151-155

Rebeca Ostan, Lavinia Laza, Iuliana Popescu

Vitamin B12 is found in most animal derived foods, including fish and shellfish, meat (especially liver), poultry, eggs, milk, and milk products. However, the binding capacity of egg yolks and egg whites is markedly diminished after heat treatment. Vitamin B12 is a nutrient that helps keep the body's nerve and blood cells healthy and helps make DNA, the genetic material in all cells. Vitamin B12 also helps prevent a type of anemia called megaloblastic anemia that makes people tired and weak. Two steps are required for the body to absorb vitamin B12 from food. First, hydrochloric acid in the stomach separates vitamin B12 from the protein to which vitamin B12 is attached in food. After this, vitamin B12 combines with a protein made by the stomach called intrinsic factor and is absorbed by the body. Some people have pernicious anemia, a condition where they cannot make intrinsic factor. As a result, they have trouble absorbing vitamin B12 from all foods and dietary supplements.

INFLUENCE OF SOWING TIME ON PRODUCTION CAPACITY A FEW LINES OF SAFFLOWER (CARTHAMUS TINCTORIUS L.) UNDER TIMISOARA pag. 156-159

Dorin Popa, Simona Niţă, Ioana Maria Mateaş

Abstract :Safflower was grown for its flowers, used for coloring and flavoring. Safflower name derives from the fact that it was cultivated as a cheaper alternative to saffron. This content carthamin because flowers, like saffron. Safflower flowers have a calming qualities of cough. Pigments from safflower flowers are particularly important because they leave no toxic residues colored products. Pigments which are synthesized in roots during vegetation migrate through tissues leading the petals. Carthamina is one of the most valuable non-toxic compounds used in the food or in the textile industry. The seeds are used to treat tumors, especially those located in the liver. Flowers are considered laxative properties, sedative, and is used to treat scarlet fever. Indicated that safflower oil is widely used in pharmaceutical industry and antirheumatism detention purgative effect, not oil in the diet increases the amount of cholesterol in the blood. The oil is used as a remedy for rheumatic pains. Chinese medicine recommends seeds to treat dysmenorrhea in women, they having an astringent effect on the uterus. Outside the fatty acid content of 32-40% and a percentage seeds contain 11-17% protein and 4-7% water. To emphasise the yielding capacity of some new lines of safflower (Carthamus tinctorius L.) under study, we organised, in 2013, a bi-factorial experiment in which experimental factors were as follows: Factor A – sowing time - 1st time MARCH - 2nd time MAY Factor B – safflower lines - T 9, - T 10, - T 33, - T 40 short line. The experiment was set after the randomised block method. The experimental variants were set with three replications with randomisation of the Factor B (safflower lines). Research has shown the influence of planting dates on productivity elements obtained from testing of new lines of safflower. To achieve the objectives of the research were used 4 lines of safflower obtained by individual selection from a population of Timisoara.

PRELIMINARY STUDY ON CONTENT AND OIL PRODUCTION IN SOME LINES SAFFLOWER (CARTHAMUS TINCTORIUS L.) UNDER TIMISOARA pag. 160-163

Dorin Popa, Simona Niţă, Ioana Maria Mateaş

Abstract: Safflower (Carthamus tinctorius L.), as an oil plant, has been known since ancient times. It is cultivated in U.S.A., Israel, Morocco, Spain, Italy, France, Pakistan, Tunisia, India, and Australia. Safflower has been cultivated mainly for the edible oil obtained from its seeds. It is mentioned that safflower oil has wide uses in the pharmaceutical industry, due to its purgative and anti-rheumatism effects. It does not result in an increase of the cholesterol level in the blood. Safflower flowers have tonic properties in cough. Pigments of safflower flowers are particularly important because they leave no toxic residues in coloured products. Pigments are synthesised in the root where, during vegetation, they migrate towards leading tissues towards the petals.The oil is used as a remedy for rheumatic pains. Outside the fatty acid content of 32-40% and a percentage seeds contain 11-17% protein and 4-7% water. Carthamine is one of the most valuable non-toxic compounds used in the food industry or in the textiles industry. Results obtained recently in China concern the use of safflower flowers-based medicines with good effects on coronary diseases and on angina pectoris, curing 75.6% of the total patients treated. The incidence of re-occurrence of cardiac crises as well as of side-effects is rarer than in the case of nitro-glycerine-based medicines. In order to reach the goals of our research, we used 4 safflower lines obtained through individual selection from a population of Timişoara. To emphasise the yielding capacity of some new lines of safflower (Carthamus tinctorius L.) under study, we organised, in 2013 a bi-factorial experiment in which experimental factors were as follows: Factor A – sowing time - 1st time APRIL - 2nd time MAY Factor B – safflower lines - T 9, - T 10, - T 33, T 40 short line. * T - Timişoara Research carried out pointed out the impact of sowing time on yield as a result of testing new lines of safflower.

THE DYNAMIC-ENERGETIC SIDE OF STUDENT’S PERSONALITY AND ITS ROLE IN SCHOOL SUCCESS pag. 194-199

Iasmina Cecilia SAVESCU, Alina Lidia MĂRGHITAN, Manuela Dora ORBOI

Abstract: The purpose of this paper is to draw the teachers' attention on the importance of gaining insight into the dynamic-energetic side of students' personality and using the most appropriate educational methods and strategies to help them achieve success in school. This research may constitute the future basis for certain investigations regarding the actual support that each type of temperament may offer in the process of education in order to build up a desirable character within society and to achieve school and career success. The method employed in the study was that of the psychological questionnaire focusing on establishing the type of temperament and the students' perception on the involvement of temperament awareness in school success. The value of this research does not reside in the increasing novelty of the subject, since starting with Hippocrates and Galen people had already known about the characteristics of temperaments, but in the redefining of this aspect in an educational, pragmatic context. The limitations of the research comprise a quota sampling of only 60 students, whereas the study may unfold on a larger scale to gain more statistic relevance. The results of the investigation under scrutiny emphasize the students' belief that personality and psychological potential constitute the basis of academic success to which the teacher contributes through knowledge application. Their view elicits the fact that there are deficiencies in using temperament as a learning pillar, claiming that some dominant types are at advantage compared to others in the process of acquisition. The study is useful mostly for teachers with a propensity for students' academic success through the efficient and favorable use of their dynamic energy potential. The paramount importance of the research in question resides in the motivation of teachers to gain insight into the different temperaments of pupils and use them to achieve an increased rate of efficiency in the process of education.

NITROGEN LEVEL IN SOIL AFTER MINERAL FERTILIZATION pag. 207-213

Andreea Tița (căs. Golea), Isidora Radulov, Iulia Nanu

Abstract Of all the essential nutrients, nitrogen is required by plants in the largest quantity and is most frequently the limiting factor in crop productivity. Proper management of nitrogen is important because it is often the most limiting nutrient in crop production and easily lost from the soil system. In this paper are presented some results regarding the nitrogen dynamics in soil after mineral fertilization. The researches have been made on soil intensively fertilized with mineral fertilizers without micronutrients. Intensive mineral fertilization was made on winter wheat. The experiments were of bifactorial type, with 5 variants and 4 repetitions. Experimental variants were: nitrogen fertilization N0 (0 kg/ha), 2 – N50 (50 kg/ha), 3 – N100 ( 100 kg/ha), 4 – N150 ( 150 kg/ha), 5 – N200 (200 kg/ha) and Phosphorus and potassium fertilization: 1.– P0K0 (0 kg/ha), 2-.P50K50 (50 kg/ha), 3.-P100K100 (100 kg/ha),4.- P150K150 (150 kg/ha). Fertilizars used were: ammonium nitrate and complex mineral fertilizer 15:15:15. Parameters analyzed were: pH, total nitogen, amonium nitrogen and nitrates. The usefulness of the resarch is very important, because world-wide every year are applied great amounts of mineral fertilizers and nitrogen is a key element for plants.For the cultivars this type of information is very important because they can apply in a durable and cheap way the fertilizers. The largest quantities of nitrogen were determined in the cold season (December), because the leading low temperatures had reduced the leaching.

Daciana TURCUŞ

Diversity of cormophytes from 3 sites (Bodrog Bezdin and Cenad) belonging to Mureş Floodplain Natural Park, is analyzed in terms of number of species, families and biological types. Overall in 2013 we studied 124 plots, most with cereals (wheat, barley and oats) and corn. The degree of weed is expressed as a percentage (%) of the soil surface covered their aerial parts and the projection on the ground. Vascular flora of weeds is represented by 205 species belonging to 40 botanical families. The average number of weed species per plot ranges between 16,70 and 19,5, in the case of cereals and 15,25 to 20 in the case of main weeding species (corn and sunflower). Specific biodiversity in the weeds group is poorly correlated or uncorrelated with the soil properties (pH and humus content) and size of the plots studied.

THE INFLUENCE OF TEMPERATURE ON THE GROWTH LIMIT OF ACETIC BACTERIA PRESENT IN SAUVIGNON WHITE WINE WITH A CONCENTRATION OF 13% ALCOHOL pag. 223-230

Carmen Vlădulescu, Gheorghe Matei

Temperature is a determinant factor of the vital-metabolic processes of acetic bacteria. Changing wine into vinegar progresses more rapidly as the temperature is raised. Volatile acid alteration is at the beginning twice faster at 280C than at 230C and twice faster at 180C than at 230C. The scale of heating values along which starting from minimum temperature and to the maximum, the bacteria are able to perform normal vital activity, represents the area of growth temperature. Broad limits which extends the range (0 - 450C) places acetic bacteria in mesophilic microorganisms category for which the limit temperature increase is 40 - 450C. The limit temperature for thermal destruction or death ran for acetic bacteria, between 55 - 600C. The optimum temperature for growth for vital processes to take place with maximum intensity, is conventionally defined as the temperature at which cell proliferation is the most intense mode. However, this value does not coincide with that of the thermal optimum temperature for physiological activities of the cell. Maximum temperature of growth supported by acetic bacteria is the greatest heat where the biological activity is still possible, and multiplication of such micro-organisms can still be carried out. Exceeding this threshold heat affects reproductive capacity of acetic bacteria. Minimum temperature for acetic bacteria vary by species between 8 and 100C and represents the lowest heat at which cell multiplication, although very slow, can still be achieved. Theoretical the limit of development of vital processes is determined by the freezing temperature of the water. It is important to know, in oenological practice, the optimum growth temperature for the acetic acid bacteria is between 25 - 300C. In general, there were no increases in excess of bacteria colony, over 370C, but we managed to isolate several thermotolerant strains at 37 - 400C. At lower temperatures, acetic bacteria are still active even at 100C. As a result, it is difficult to draw a strict temperature range in which these bacteria can grow, the temperatures used during the wine making process seem not to affect the growth of acetic bacteria.

USAGE OF E-TERRA IN REAL ESTATE AND URBANISTIC REGISTER pag. 231-241

Lucian O. DRAGOMIR, Paul M. ZELENCA, Iasmina TODICA, Andrei VILCU

E-Terra Information System manages technical and legal information related to real estate. The main objectives of the application are: streamlining and computerization of OCPI main work streams, automating certain processes (where possible), standardization of working papers, information security events tracking system, reduce documents filed on paper, reduce the time for solving applications and rapid access to archive data. E-Terra Cadastre Module is intended for inspectors from OCPI / BCPI who need to check the documentation prepared in specialized cadastre in Romania and allows approval and acceptance of works cadastral map and cadastral consulting related textual information. Module e-Terra Land Register is intended for inspectors from OCPI / BCPI who need to check documentation specialist. Land Register is a public record, which includes full and accurate legal records of properties owned by individuals and entities in the same locality. Using e-Terra has a number of advantages such as streamlining the functioning OCPI execute any operation, automatic distribution of work and can be checked at any time each work stage, converting the classical Land Register to digital, high precision concerning the geometry of the building.
