THE CHARACTERISTICS OF SOME ANIMAL SPECIES FROM DOLJ COUNTY AND THE IMPORTANCE OF THEIR CAPITALIZATION
Get PDFDolj Forest District manages a surface of 59 800 ha public forest fund and 9 125 ha private property forest fund. Non-wood forest products represent an important part for all industries, as well as for the gastronomic and artisanal domains. In this context, the present paper presents the importance of capitalizing game species and the need for this sector`s development, by taking into account three species frequently found in this area. The crop goose (Anser fabalis) is a species with a high price for the raw product as well as for the derived products. Partridge (Perdix perdix) has a smaller harvesting period and distribution range and the largest quantities are found in forest units of Amaradia, Perişor and Filiaşi. Pickerel (Esox lucius) is a very popular species, with a high selling potential and an increased market request. These species belong to the 8 game species that were analyzed through the AHP interval based on 19 criteria
IMPACT OF GRANULAR FLOW DYNAMICS ON THE DESIGN AND MODELLING OF THE BUNKERS
Get PDFSilos and bunkers are widely used in the storage, storage and distribution of granular materials, of particular importance in the management of handling, transport and conditioning operations. The distribution of seeds at the filling and emptying stage of the bunker examines the main loading and unloading hypotheses leading to different limit states for its structure. This paper will present the results of causes such as the maximum pressure perpendicular to the vertical wall of the silo, the maximum stretching effort due to friction with the vertical wall, the vertical pressure on the basis of it and the maximum load on the bunker funnel, resulting in the implementation of new design and modeling solutions. At the same time, the dynamics of the granular flow in the bunkers, including flow regimes, design and optimal shapes, will be described to avoid the loss of energy generated by the collision of macroscopic particles inside it
PARTIAL RESULTS REGARDING THE ESTABLISHMENT OF THE NUTRITION SPACE FOR FODDER SORGHUM IN THE CENTRAL AREA OF OLTENIA
Get PDFPlant density is the technological element that achieves the balance between environmental conditions (light, temperature, water, nutrients) and the generic characteristics of the species, soil and cultivated hybrid.In this sense, if we refer both to the density but also to the distance between the rows of fodder sorghum cultivated on the luvisol from SCDA Şimnic Craiova, we find that the level of production is closely related to them.Thus, the grain production had values from 5.2 t/ha grains dry matter when sowing was carried out at a distance of 25 cm between rows with a density of 75 thousand pl/ha and 9.5 t/ha grains dry matter, respectively 75 cm between rows and using a density of 150 thousand pl/ha.The crop increase was in the latter case the highest, namely 4.3 t/ha of grains dry matter compared to the control studied
STUDY REGARDING SOIL QUALITY INFLUENCE ON SEVERAL MEDICINAL CROPS
Get PDFSoils are living and dynamic systems that serve as interface between agriculture and the environment. Soil and water quality influence medicinal plant harvest yield, while the cultivation technologies and processes that take place during the growing season may influence soil quality. The significant decrease in soil quality is evidenced by the negative changes in its physical, chemical, biological properties and when soil is contaminated with organic and inorganic substances. The assessment of soil conservation status is performed by determining key indicators and threshold values, which must be maintained for its normal functioning, this analysis being important to determine trends of deterioration or improvement of soil quality, for various agricultural ecosystems. The main objective of this paper was to determine a series of indicators such as: physical indicators (particle size, humidity, density), chemical indicators (pH, conductivity, N:P:K content), and organic content from soil, in order to evaluate soil and water quality, on a field cultivated with several annual and perennial medicinal plants (basil, marigold, hyssop, lemon balm, lophantus, etc.)
STUDY ON THE PREPARATION OF THE TECHNICAL DOCUMENTATION REQUIRED FOR REGISTRATION IN THE LAND BOOK OF A PROPERTY IN KLADOVO – SERBIA
Get PDFThe study is carried out in collaboration with Serbian students from the MTC, from the Faculty of Agronomy of the University of Craiova and with a company from the same country, in order to make a comparison and analogy between the methods and procedures of surveying used in the two countries (Serbia and Romania). The paper presents a case study conducted in the town of Kladovo in Serbia in which a private property was taken into account, which must be registered in the Land Book. In order to solve all the requirements of such a work, a modern and new method was applied, used more and more in the topo-cadastral surveys, namely the combined method GPS and total station. From the surveys carried out in the field and processed at the office, it is found that the methodologies and working procedures are identical to those used in our country. It is also found that the equipment used is very modern and high-performance, which allowed to obtain a very high precision and a high economic efficiency of the work. In the end, the technical documentation prepared strictly complied with all the requirements of the legal norms imposed in Serbia and was done with great precision, which allowed it to be submitted to the office of the Land Book and the registration of the property studied in it. The significant difference between the technical documentation prepared for this property in Serbia and the documentation made in Romania is the Gauss-Kruger coordinate system in which the boundary points were determined, compared to the 1970 Stereographic system used in our country
THE ECOLOGICAL RECONSTRUCTION THROUGH AFFORESTATION WORKS ON THE RUNCURELUL DUMP HAVING THE AREA OF 27 HA
Get PDFIn recent decades, surface mining operations, especially in the mining basin of Oltenia, have developed a lot and as a result there have been large areas with degraded land and tailings dumps whose ecological reconstruction has been and is a topical issue.The Runcurelu Dump is located within the Jilţ Quarry, the territory of commune Mătăsari, more precisely in the Runcurelu meadow and is free of technological tasks. The spontaneous vegetation settled quite well, especially on the first plateau. Because the piled material was deposited in a completely random way, the surface of the perimeter is largely uneven, especially on the two slopes that border the plateaus. On the slope the slope is large and complex, ranging between 25-35% and over.From a geological point of view, the studied perimeter is very complex, belonging to both the Pliocene (Levantine) and the beginning of the Quaternary and Dacian (sands).Lithologically, it is represented by various inhomogeneously mixed geological materials. Following the coal mining process, respectively the dump process, the geological deposits of a great diversity were brought up to date and mixed very heterogeneously.The diversity of dumped materials is observed both chemically and physically. In this dump are alternately deposited all sorts of materials, from clays, marls, to sands with smaller or larger coal fragments
CONSIDERATIONS ON THE PROTECTION OF VINEYARDS AND ORCHARDS AGAINST HOAR AND FROST
Get PDFNo matter how favourable the light and humidity conditions may be, plant growth stops when the air and leaf temperature drops below a certain minimum or exceeds a certain maximum value. When air temperatures drop below 0 °C, susceptible crops can be injured, with significant effects on production. Hoar and late frosts occur differently, there are areas where the number of days in the spring months with critical temperature drops are quite numerous, with a frequency in April and exceptionally during May. The negative effect is all the greater as it is recorded after a warm period which can cause an advance of the period of formation of flower buds and the appearance of flowers. The paper presents a series of considerations on the protection of orchards and vineyards against hoar and late frosts
MODERN METHODS FOR FOOD PRODUCTS PRESERVATION
Get PDFBacteria, molds and yeasts are microorganisms that play an essential role in spoiling food. Food products preservation technologies are intended to reduce the intensity of the activity of pathogenic microorganisms that generate decomposition processes. From the point of view of food technologies, heat treatments (pasteurization, sterilization) are the main way of preserving food. The trend is to minimize or replace heat treatments with nonthermal, non-destructive methods, in order to preserve the freshness, nutritional and bioactive value of the food products. This paper presents the working principles and the effects of various modern methods of preservation, thermal and athermal, on food
STUDY REGARDING THE VALORIZATION OF A LAND TAKEN INTO CONCESSION, BELONGING TO THE MUNICIPALITY OF CLUJ-NAPOCA
Get PDFA case study was prepared in the course of the paper on the concession of a building belonging to Cluj-Napoca, with the aim of dismantling it resulting in 32 parcels and the access road to them, with a view to authorizing the construction of 32 youth housing. The legislative framework on the possibility of the concession of property owned by the State or its territorial entities is also presented. The proposed street to be carried out within the framework of the housing complex, which will be built following the concession, is 1703 m long and 1.50 m wide. The aim is to ensure a 6 m carriageway for two directions, a bicycle path and a pavement on either side of the roadway. The assessment of the investment for street planning, plus the cost of the drinking water and sewerage network, the electricity grid, the natural gas network and the selling price of the undeveloped land, represents the minimum concession price limit per sqm, so as to ensure the recovery in 25 years of the selling price of the land. Following the analysis carried out, the proposed minimum starting price of the auction is 2051 RON/sqm (435 €/sqm)
PRELIMINARY STUDY REGARDING POSSIBILITY TO USE UV-C RADIATION ON MEET PRODUCTS
Get PDFIn a world where food safety not only can no longer be ignored but new rules appear, experts in the field are looking for new and new solutions. Sometimes we return to the ideas that were abandoned in the past due to the economic efficiency. Given that the production of electricity is becoming cheaper due to renewable resources, the pasteurization of meat products through UV-C radiation can be one of the solutions
