MODERN TECHNOLOGIES USED IN MINES SURVEYING
Get PDFToday`s technology is changing the face of surveying. The goal of any survey is still categorized into two specific areas: collecting spatial data and positioning spatial data. With all this progress, the huge influx of data as well as these new technologies represents a particular challenge for the working methods and equipment used today. The use of laser scanning and the use of unmanned aerial vehicles (UAVs) that create this data, together with software solutions that maintain, display, analyze and manage large amounts of spatially located digital data are necessary. Because spatially located digital data provides a different level of visibility to a business, it becomes highly sought after for a wide variety of users within a mining enterprise. The ability to efficiently manage, maintain, and disseminate this spatial data to the right people at the right time will be critical to the success of an enterprise
OVERVIEW OF METHODS AND TOOLS USED TO DETERMINE THE QUALITY OF WHEAT STORED UNDER VARIOUS CONDITIONS
Get PDFThe requirement of new efficient, rapid and reliable techniques for assessing the content and quality of wheat proteins has led to changes in the available methods as well as the development of new methods. The empirical processes used to determine wheat quality are the basis for the development of new methods and equipment designed to facilitate and improve the way in which the characteristics of cereals stored in the long term are determined. Many factors influence the quality of wheat, including: storage mode, methods to combat infestation, the influence of environmental factors, all of which lead to the degradation of the grain over time. The objective of this work was to assess the newest methods and equipment used to specify the quality of stored cereals
THE PRICE OF SOME DAIRY PRODUCTS IN ROMANIA (2014-2018)
Get PDFIn the recovery circuit, the milk of cow, sheep, goat and buffalo is taken over. The largest share belongs to cow's and sheep's milk. The food functions of milk are complex being one of the most complete foods. For this reason, milk is considered a strategic product of the agri-food market, which is used as such in its fresh state or is processed. At present, food technologies use milk in the following forms: as such, in the fresh state, a situation in which the conditioning of fresh milk for consumption takes place or is transformed into concentrated milk and powdered milk; by processing in the form of dietary dairy products and cheeses, by selective extraction of the resulting components cream, butter, skim milk and others; in combination with other materials, food, ice cream, etc. are prepared. Positioning of processed products in relation to raw material prices (fresh cheese and Telemea cheese from cow's milk compared to cow's milk; Telemea cheese compared to sheep's milk). Compared to the reference levels, the processed products achieved: advances from 7.03 to 8.28 times for fresh cow's milk cheese, with an average advance of 7.32 times; exceeding 9.84 times in the case of matured cow's milk cheese - the average of the period, with limits of 9.45 and 11.16 times in the case of 2017 and 2018, respectively; advances from 5.18 to 7.06 times (2016 and 2014, respectively) for sheep's cheese matured (5.57 times the excess recorded for the average of the period)
STUDIES AND RESEARCHES CONCERNING CORN SILAGE HARVESTERS
Get PDFSilage is one of the basic forms for preparing feed for ruminants, especially during the period for calves. Thus in the rations for dairy cows, it represents 40-50% of the total nutritional value. A particularly important role is played by mechanization technology for the preparation of the silage, using appropriate harvesting means. Combine harvesters for fodder plants are complex machines that can perform several technological operations such as: cutting plants, chopping and loading in the means of collection or lifting the material from the furrow. Harvesting fodder plants with the help of combines is the solution with the most significant advantages, because in this case high quality fodder is obtained, the complete mechanization of the harvesting process is ensured, the harvesting material requires a low consumption of live labor
RESEARCH ON DEVELOPING A MULTIFUNCTIONAL EQUIPMENT FOR HARVESTING MEDICINAL AND AROMATIC PLANTS FOR USE ON SMALL AREAS
Get PDFCultivation technologies of medicinal and aromatic plants characterize harvesting operations as being difficult, because they have a significant effect on the plant material quality. Therefore, regardless the harvesting method used (either manual or mechanical), the intervention on the useful part of the plant have to be kept to minimum. Mechanized harvesting is usually an important prior factor for achieving profitable productions, and this aspect is also valid for medicinal and aromatic plants. In order to improve and adapt the cultivation technologies to the current Romanian requirements, and analyzing previous practical experiences, INMA Bucharest has achieved a multifunctional equipment for harvesting annual and perennial medicinal and aromatic plants, with applicability on small land surfaces. The paper presents the experimental model of an innovative equipment and the expected advantages, compared to the previously made harvesting equipment
GENERAL CHARACTERIZATION OF THE MAIN SOILS IN OLTENIA AREA
Get PDFSituated safely under the Carpathian chain, between the Danube and river Olt, the geographical area of Oltenia presents a wide natural frame, witch determined a great diversity of the pedological cover, forming a true natural soils museum.In the plain area, on the plateau, on loessoid deposits were formed and chernozems are met. Continuing the chernozems, on more humid areas, covering almost entirely the area from steppe to forests, there are present the cambic chernozems and argic chernozems.In the southern central area of the region, determining from pedogeographical point of view the transitional type between argic chernozem and preluvosoil from the hill area, there are present the reddish preluvosoil and luvic reddish preluvosoil.         The preluvosoils, luvosoils and albic luvosoils, are spread in the hill and table-land area, assigned according to the relief, rock and vegetation.         On well drained plane field and on rocks rich in alkalescent elements are prevailing the preluvosoils, on plane, lowlands and acid rocks the luvosoils and albic luvosoils are formed.         In the mountain area, the soils repartition is keeping a certain vertical areal, determined especially by heights. The eutricambosoils are met on the well drained slopes and on eruptive rocks with a lot of alkalescent elements and the districambosoils were formed on rocks poor in alkalescent elements, of heights between 600-1000 m.         At higher altitudes prepodsoles were met on gentle peaks and acid rocks, podsoles were met on the highest platforms and lowlands on acid rocks, and in the alpine area on a relief formed by plateau, gentle slopes and long ridges were met the humosiosoils
