DownloadTHE ECONOMIC EFFICIENCY OF AGRICULTURAL LAND ROM THE LUGOJ LOCALITY PERIMETER, TIMIȘ COUNTY pag. 12-16
Casiana MIHUȚ, Anișoara DUMA-COPCEAIn our country, due to the high variation of pedogenetical factors, the soil layer is very diversified. At the level of the entire monitoring network, one can encounter 10 of the 12 classes at national level, and 23 soil types of the 29 mentioned by SRTS, 2012. The best represented soil classes are Chernisoils (36.0 %), followed by Luvisoils (21.2 %), Protisoils (19.1%) and Cambic soils (15.2 %). Natural conditions from the western part of Romania, including the perimeter of the town of Lugoj have been and still are extremely favourable for the development of a complex agricultural economy. Climatic conditions, humidity, rock and even relief conditions determined a diversity of soil types pertaining to most classes. Regionally, these can be found north from Mureş in the Carpathian-Crişana province, and to the south in the Carpathian-Banat province, which are part of the central European pedogeographic region. For the most part, they are high fertility soils. Within Timis county, Lugoj is located in the central eastern part, counting as the second town in the county in terms of size, economic development and population. Morphologically, the territory belongs to the High Lugojului Plain and the Lugojului Hills. Lying on the contact area of these units, the town was developed on the inferior Timiş terrace, on both shores of the river. The relief unit, where the city lies in, is the Lugojului Plain, which deeply penetrates the piedmont hill area. The average area altitude is of 124 m above sea level. At the basis of the soils identified and delimited within the perimeter, generally the following parental material groups were found: clays, argils and fluvial deposits. Deposit and evolution conditions for these sedimentary materials can provide information on the currant argillaceous materials. Of the total surface of the researched area, almost 80% represents agricultural land with predominant tillable land (75 – 90%). The rest of 4% of the land fund is represented by forest groups, 4% by settlings, communication ways, non-productive land and 1.5% is covered by water (GR. POSEA, 1995). Of the tillable land, 10 – 25 % are concentrated either in low plains (grass land on saltings and on excess humidity land) or in glacis plains (orchards, vineyards, grass land).

DownloadTHE MANAGEMENT OF SOIL RESOURCES FROM THE JIMBOLIA LOCALITY PERIMETR, TIMIȘ COUNTY pag. 17-22
Casiana MIHUȚ, Anișoara DUMA-COPCEAThis scientific paper is based on a selective evaluation of specilaity literature data on fundamental, general and particular aspects regarding soil resources of the Jimbolia locality perimeter and the establishment of these soils’ fertility. The paper objectives are as follows: caracterization of the natural frame; identification of soil resources and determination of soil fertility. Soil resources identified within the researched perimeter are generally very fertile, belonging to the Chernisoil class. There are brown soils tending towards dark brown and black. Two main chernozem types occur: the slightly gleyed classic Chernozem with insertions of carbonic, phreatic-humid and vermic Chernozems and the cambic Chernozem, often associated with psamosoils. On reduced surfaces, mollic gley soils and white alkali soils also occur. The researched perimeter is located in the western part of Romania. Within the borders of the Timiş county, it is located in the western extremity, at a 39 km distance from Timişoara city. As a geographic position, it is situated in the Banat Plain, at the contact point between the Timişului Plain and the Mureşului Plain, at an average altitude of 82 m. From a climatic point of view, it corresponds with the temperate-continental climate type specific for Central Europe, where sub-Mediterranean influences can be registered. From an agro-climatic point of view, certain restrictive factors are signaled regarding the insufficient precipitation quantity, especially during the warm season, and the relatively high frequency of droughts. Underground water can be found at a 3-5 m depth.

DownloadTHE INSTINCT OF DOMESTIC ANIMALS IN THE DARWINIST CONCEPTION pag. 23-25
RaduPalicicaBased on a rich factual material, starting with the artificial selection made from man's multi-secular practice, Charles Darwin grounded the conception of evolution of animal and plant species, evolutionism. On the basis of his doctrine stays the conception that man manages through artificial selection to create new varieties and breeds of animals, whose characters can be transmitted by crossing and can be fixed on the descendants. So does the natural selection too, but slower and with the same results. So appear new species capable of surviving and transmitting characters. The underlying cause is the struggle for existence, imploying evolutionary the species, according to the survival of the fittest.

DownloadINVESTIGATIONS ON THE QUANTITY OF DEZOXYRIBONUCLEIC ACID (DNA) FRAGMENTED FROM NUCLEUS OF HUMAN SPERM CELL pag. 26-30
Mihaela OSTAN, Anca-Laura STĂNIA, Olga-Alina RADA, Raluca POPESCU, Delia HUŢANUInfertility is “a disease of the reproductive system defined by the failure to achieve a clinical pregnancy after 12 months or more of regular unprotected sexual intercourse.”(Zegers-Hochschild F. et al., 2009). This paper presents an aspect of male infertility, the percent DNA fragmentation from sperm’s head and it’s clinical application. To obtain the percent of DNA fragmentation from sperm’s head we used sperm chromatin dispersion test commercialized under Halosperm test name. One of the factors involved in male infertility is the percent of DNA fragmentation from sperm’s head. The present study was made at Gynatal Clinic from Timisoara, on 25 male patients, who addressed to the Clinic for couple infertility between June 2015-May 2016. The female partner was tested and the couple’s diagnostic was idiopathic infertility. After the female partner was tested and excluded as a cause for the couple infertility, the sperm count and the percent of DNA fragmentation from sperm’s head were performed. These tests were made in order to achieve more information and to help the specialist to choose the adequate human assisted reproductive technique. After this study, we may conclude that the measurement of the percent of DNA fragmentation from sperm’s head has practical relevance. Taking in consideration the results of the percent of DNA fragmentation from sperm’s head test, the specialist can decide the most suitable human assisted reproductive technique in order to maximize the attempt.

DownloadWESTERN CORN ROOTWORM AND EUROPEAN CORN BORER – FLIGHT DYNAMICS IN VOJVODINA PROVINCE, SERBIA pag. 31-38
Snežana, TANASKOVIĆ1, Branka, POPOVIĆ1, Sonja, GVOZDENAC2, Zsolt, KARPATI3, Chengele, BOGNAR3, Matthias, ERB4Western corn rootworm (WCR) and European corn borer (ECB) coexist in the Serbian maize fields for the last 25 years. It is poorly known how does the WCR, as a soil dwelling insect, influence the appearance and abundance of ECB population in the same field and vice versa. Three-year experiment was conducted in Bečej, Vojvodina province, Serbia. Aim of the study was to determine the flight dynamics of WCR and ECB under artificial infestation with WCR eggs, and preliminary indentify ECB strain in pheromone traps. During three years, the presence of different ECB strains was verified. Population dynamic, according to obtained data, indicate high differences in population abundance. The occurrence of this pest in the field fluctuates. The earliest catch was on 2nd June (2016) and the latest on 17th July (2014). In 2015, when the highest temperature and the lowest humidity were registered, the first ECB specimen was caught on 23rd June. The last catch of moths was earlier in vegetation on 20th August (2014) and the latest on 9th October (2016). In 2015, the last catch was on 10th September. Preliminary results signify the presence of Z pheromone race in the north part of Serbia. Flight of WCR fluctuates during experimental years. The first catch was registered during the first week of July, and last in August 2014-2015, i.e. September 2016. The WCR highest catch, 181 specimens, was recorded during the last field inspection, on 30th September 2016

DownloadOPTIMISING MECHANISED TECHNOLOGY IN WHAT IN THE CONDITIONS OF BAZOȘ, TIMIȘ COUNTY, ROMANIA pag. 39-42
Anișoara DUMA COPCEA, Casiana MIHUȚ, O. ARSENEAdvanced, performing agriculture from the perspective of yield and labour productivity in different countries is based on an important technical and economic segment: mechanisation of soil works. Equipping modern sustainable agriculture according to peak country expertise in the field is done with machines and equipment among which energy equipment are of great economic importance and efficacy. For Romania, with its great agricultural potential per capita and with favourable soil and climate conditions, it is important to increase labour productivity by increasing the degree of mechanisation on agricultural holdings. Straw cereals cover an important area in Romania, with wheat ranking first among cops. From a cropping science point of view, wheat cultivation is completely mechanised. Studies were carried out in the conditions specific to the Timis Plain and they concerned wheat, the crop with the widest cultivation area in the Banat’s Plain. The mechanised works in wheat were stubble-turning, ploughing, fertilising, preparing the germination bed, sowing, treating with herbicides and harvesting. These works were done with modern tractors and agricultural machines of high productivity. In mechanised works in wheat we determined the following technical and economic indices: productivity of agricultural aggregates, fuel consumption, direct costs, auxiliary costs, material costs and profit. These indices were reported in the technological charts of mechanised works. Studies allowed us to draw a few conclusions on the optimisation of mechanisation in wheat. The system of agricultural production is represented by the manner in which an enterpriser combines products, factors, and technological and economic measures at hand to practice crop rotation and reach desired economic outcomes. Choosing crops and cultivars, carrying out works in due time and of high quality, carefully monitoring the evolution of its components, ensuring optimum density in plants per ha, all this depend on skills, aptitudes, creativeness and inventiveness of the managers of agricultural holdings. For Romania, a country with a huge agricultural potential (arable land per capita and favourable climate conditions), it is important to increase labour productivity by increasing the degree of mechanisation of agricultural holdings.

DownloadSTUDIES REGARDING GRAIN LOSS IN STRAW CEREALS pag. 43-45
Anișoara DUMA COPCEA, R. ILEA, I. CRÎSTAHarvesting straw cereals is the most important mechanised work in July. To cut the losses to a minimum, harvesting with self-propelled combines is done upon full ripening. To cut the losses, fields should not be weeded or have fallen plants and combines should be fixed depending on the field state. In weeded fields, harvesting is done by cutting plants with wind-rovers, letting them dry and harvesting with lifting equipment attached to the combines. To avoid loss during harvesting, we need to choses the plots to be harvested depending on the ripening state of the crops. It is recommended to cultivate several cultivars with different ripening periods to reach maximum harvesting time. These last years, there has been spectacular evolution in self-propelled straw harvesting combines, which now are highly performing from the point of view of productivity, reliability, automation, the quality of the harvested crop and comfort in operating. To determine properly losses upon harvesting straw cereals, we need to evaluate yield before harvesting. Upon harvesting, we need to determine losses and to take measures to reduce them through properly fixing straw harvesting combines. The main losses in harvesting straw cereals depend on field state, on the flow of the thresher, on combine tightness, on self-propelled combine fixtures, etc. Losses are determined for each case apart and are presented quantitatively and as percentage depending on the yield evaluated. Using straw harvesting combines with a feeding flow above optimum causes higher losses. Optimum feeding flow is established depending on the type of the harvesting combine and on the field state, so that grain losses range within admitted limits. Using straw cereal harvesting combines rationally at the optimum time ensures minimum loss and low expenses.

DownloadCHANGES OF BLOOD CELLS IN THROMBOCYTOPENIA IN HUMANS pag. 46-52
Mihaela OSTAN, Alina Surdilă, Corina Luminiţa MĂRAN, Jelena SAVICI, Olga-Alina RADAThrombocytopenia is a condition characterized by low number of platelets (thrombocytes) and leads to disruption of coagulation or hemostasis, manifested by increased bleeding time and clotting. The incidence of thrombocytopenia reported in the literature is between 13 % and 41 % and is associated with increased mortality and length of hospitalization. The purpose of this paper is to highlight changes in quantitative and qualitative of platelets and emphasizing the importance of haematological investigations (cell blood count, peripheral blood smear, bone marrow smear) in orientation for subsequent diagnosis thrombocytopenia. The material used in the study was the 25 blood smears, respectively 9 bone marrow smears and clusters crushed by bone marrow. CBC examination results revealed severe thrombocytopenia, platelets representing 27.25% of the minimum reference value in healthy individuals. Associated it was observed 74.89 % reduction in red blood cells count, in hemoglobin 77.91 %, hematocrit to 82.80% and reduction with 29.20 % of total leukocytes from the minimum reference value. The blood count was found to drastically reduce the proportion of granulocytes, monocytes 25% reduction and the increase of lymphocytes twice. Examination of blood smears revealed changes in platelet morphology (presence of macrothrombocytes and platelet aggregates) associated with morphologic changes in white blood cells (blasts presence on smear) and in erythrocytes (dacriocite, anisocytosis and hypochromia). Bone marrow smear revealed that approximately 33.33% of study smears present trombocitogen megakaryocytes activit, which indicates that bone marrow is functional and marrow produces platelets; 66.66 % of smears from bone marrow megakaryocytes examined were absent, probably stored in the spleen or their production was blocked by the presence of other inhibitors, may immune or hereditary cause.

DownloadPERENNIAL HERBACEOUS SPECIES SIDA HERMAPHRODITA AND POLYGONUM SACHALINENSE FOR RENEWABLE AND SUSTAINABLE ENERGY IN THE REPUBLIC OF MOLDOVA pag. 53-60
Victor ŢÎŢEI, Andreea Cristina CIOPATĂThe sources of renewable energy have acquired considerable interest in recent years, at global and national level. The investigation of introduced herbaceous plant species for further processing into diverse types of bio fuels is an important objective. We investigated the biochemical composition and some thermo physical properties of the biomass of local varieties of non native perennial herbaceous plant species: Energo of Sida hermaphrodita and Gigant of Polygonum sachalinense, created and cultivated in the Botanical Garden (Institute) of the Academy of Sciences of Moldova, maize (Zea mays) – control variant. It has been established that the gas forming potential of digestible organic dry matter from the green mass substrate of the studied perennial species varied from 454 to 460 l/kg and 451-458 l/kg – of silage substrate; in maize substrate – 536 l/kg and 557 l/kg. Polygonum sachalinense substrate had higher content of methane (54.6 %) and methane production potential (4000-4850 m3/ha). The biomass of the studied perennial species was characterized by high bulk density (172-225 kg/m3) and gross calorific value (18.7-19.3 MJ/kg) and reduced ash content (1.5-2.6 %), but maize stalks – by low bulk density (152 kg/m3) and calorific value (17.9 MJ/kg) and high content of ash (4.6 %); the gross calorific value, as a solid fuel, accounted 350-435 GJ/ha. The dry biomass of local varieties was characterized by high content of cellulose (511-535 g/kg), hemicellulose (256 -307g/kg), pentose sugars (91-96 g/kg) and hexose sugars (47-51 g/kg), in comparison with maize stalks (417 g/kg; 250 g/kg; 75 g/kg and 41 g/kg). The theoretical ethanol potential was 19-26 % higher and constituted 557-614 l/t dry matter. The obtained results indicate the possibility of using the local varieties Energo of Sida hermaphrodita and Gigant of Polygonum sachalinense for the creation of plantations to produce biomass energy for multiple purposes in Moldova.

Dana Lucia SubaKnowledge of the general combining ability, ie the additive genetic component passed on by a parent to all his offspring, has a very high practical relevance in corn breeding programs. The objective of the research was to evaluate the additive genetic effects (general combining ability). The overall ability to combine inbred lines is particularly important in making valuable hybrids. By crossing known inbred lines with a high overall combining capability (for production or for another character) in a dialel system, it is normal to carry out a hierarchy of the respective inbred lines.
