Observaţii cu privire la fauna epigee din culturile de grâu în condiţiile anului 2017
No full textThe observations were made in 2017, in a wheat crop located in the eastern area of Romania, in the county of Vaslui. The material was harvested using the soil traps type Barberand entomological mesh, during which several harvests of the material were made at intervals of 8 to 15 days. From the collected biological material, were retained all the species belonging to the epigee fauna, which were then determined by means of the determiners (Reitter, Panin, etc.). Following the records was established the specific structure from wheat crop, their dynamics and their abundance.The most frequently collected species were: Heteroptera, Hymenoptera, Diptera, Aracnidae, Orthoptera, and of course those belonging to the order of Coleoptera (Pseudophonus rufipes Mull., Dermestes laniarius Illig., Harpalus aeneus F., Harpalus distinendus Duft., Ophonus azureus F., Opatrum sabulosum L., Otiorrhynchus raucus F., Carabus violaceus L., Pseudophonus rufipes, Harpalus aeneus F.şi Amara crenata Payk) etc
Influenţa diferitelor proporţii de amestecuri de vinuri roşii asupra indicatorilor senzoriali şi stabilirea parametrilor fizico-chimici a acestora
No full textRed sparkling wines produced in Moldova occupy a special place on the wine market, but to improve the quality of the finished product it is necessary to improve the technological regimes for manufacturing base wines for this category of wines. From these reasons, study was conducted on different raw red wines, from classical European varieties Cabernet Sauvignon, Merlot and Pinot Franc, comparing the influence of different composition of red wines blends on the organoleptic indices and establishing their physic-chemical parameters. As a result composition of blends from raw red wines and optimal content of phenolic substances including anthocyans, for red sparkling wine production was establishe
Studiul histerezisului capilar în soluri cu textura medie folosind modelul Preisach
No full textThe purpose of this paperis to studythe physical properties of the soil using a phenomenological model which should be able to describe the capillary hysteresis of water from pores of the medium-textured soil.The proposed model is Preisach typeand has been used successfully to describe the hysteresis of nonlinear phenomena in physics, biology or economics. This model has the advantage ofbeingeasily adapted. We had expanded this model to study the pressure exerted by water in the processes of drying and wetting of the soil. The developed and implemented model, unlike other models, takesintoconsideration the way in which interconnected pores are filled and emptied.Our study presents a new method of assessing the water circulation in soil pores with medium texture from greenhouses. The results are useful to make the irrigation systems used in gardening more efficient, from economicalpoint of view
Consideraţii privind valorificarea apelor pluviale la udarea ”zonei verzi” a oraşelor
No full textRain-waters have a problem of exploitation in any sewer system. European rules require the development of sewage systems for urban wastewater in Romania. Storm water must be collected and discharged separately from domestic and industrial wastewater. Some of the rainwater can be harnessed in the collection area by using them to supplement the volumes of water required to extinguish the fire. Rain-waters can be used to wash streets and platforms in localities. But an effective recovery of rainwater takes place in irrigation systems of green spaces. The sewer system consists of collectors, main collectors and storage tanks. The irrigation system of green spaces consists of water tanks, pumping stations and pipeline networks for the transport and distribution of water. The watering methods adopted are aspersion, micro-spraying, dripping and underground watering. The case study completed confirms the desirability of using pluvial waste water when watering green spaces

Changes in germination and seedling growth of different cultivars of cumin to drought stress
No full textCumin (Cuminum cyminum L.)
is one the most appropriate choice for
investing in dry and semi dry areas. In order
to analyse influence of drought stress on
germination and seedling growth of two
masses of cumin, an experiment was
conducted in seed technology laboratory of
Faculty of Agriculture of Islamic Azad
University of Isfahan, in 2016. In this
experiment, polyethylene glycol (PEG
6000) at six levels (0, -0.144, -0.18, -0.216
and -0.288 MP) and NaCl at six levels (0, 4,
5, 6, 7, and 8 ds/m) and distilled water as
control were applied to investigate the
influence of dryness and salinity stresses on
seed germination and seedling growth of
two cultivars of cumin plant masses
gathered from Mashhad-e-Ardahal and
Kerman, then fulfilled in two separate
factorial trials, on the basis of randomized
design with four replications. Cultivar had
significant influence on germination
percentage, germination uniformity, radicle
length, plumule length, fresh radicle weight,
dry radicle weight, fresh and dry plumule
weight. Drought stress impact on all
treatments, except germination uniformity,
fresh radicle weight and dry radicle weight
was meaningful, but, just radicle length,
plumule length, fresh plumule weight and
dry plumule weight significantly affected by
interaction between cultivar and drought
stress. The rate of germination, germination
percentage, as well as seedling growth and
establishment were considerably lowered
with the rise of stress levels using PEG.
Control treatment had obtained the highest
germination percentage, mean time of
germination, radicle and plumule length,
fresh plumule weight and seed stamina
index. Taking all traits into account, this
experiment found that Mashhad-e-Ardahal
was most tolerant hybrid to water stress

The cooperative system from Sweden agriculture: main features and evolution
No full textThe agricultural cooperative system from the countries with a market economy displayed from the very beginning a
large diversity, according to the specificity of agriculture, level of economic development, local traditions and market
development. As a result of a deep economic need, the Swedish agricultural cooperative system appeared at the end of
the XIX-th century, borrowing a great part of the Danish model. The first cooperatives set up in the Swedish agriculture
were those from the animal breeding sector, as a consequence of the development of the export of agri-food products to
England: dairies, cooperatives for eggs trading, slaughter houses–cooperatives. Afterwards appeared new sectors of
activity in the sphere of agricultural cooperative system, therefore cooperatives in the plants, forestry and agricultural
credit sectors have been set up. The majority of the Swedish agricultural cooperatives were focused on a unique
activity, fact that determined the farmers to take part to 4-5 cooperatives from different agricultural sub-sectors. In time
took place a process of cooperative merging and concentration, fact that determined the severe reduction of their
number, in the same time with the turnover increase. The most part of the agricultural production is harvested,
processed and traded by cooperatives, in the case of milk processing and trading, the market share being higher than
95%. Like in the majority of Western states, the structure of the Swedish cooperative system took a pyramidal shape,
being organized on 3 levels. The Swedish agricultural cooperatives take benefit from a specific law, and the minimum
number of members necessary to set up a cooperative is 3. In the decision making process, the principle "one person –
one vote" as well as "the proportional vote" are applied. The unique 100% Swedish cooperative that is with significant
international presence is Lantmännen supply cooperative. The majority of farmers who breed dairy cows are members
of the largest dairy-cooperative in Scandinavia – Arla Food, formed in the year 2000 by the merging of the Swedish
dairy cooperative Arla with the Danish MD Food cooperative with the same profile
Structural modification în Romanian economy
No full textChanges in the economy have been significant and dynamic with the overall result of fostering economic growth but
also with imbalances that have accumulated over time at the enterprise level and the entire economy. Several issues
have emerged, namely the need to recapitalize businesses. It has been noticed that their funding pattern has changed
significantly, raising questions of sustainability. Debt financing has replaced equity financing by generating debt
leverage, being the largest in the EU. Then, it is difficult to get in and out of the market easier. It is necessary to
stimulate the economy by setting up new companies, increasing their number but also rejuvenating them as most
Romanian companies have passed since their first youth. New businesses, but also the old ones, must focus on
innovative and knowledge-based development. Another aspect is to improve the work of tax authorities. The high level
of taxation is one of the most pressing issues for businesses. The degree of polarization and heterogeneity is required to
decrease. The degree of heterogeneity has increased, so there is only one pole of economic power in the country and
there is still no evidence of the emergence of a second. In addition, weaker economic firms have failed to improve their
economic performance over the past two decades. There are also policies that favor certain categories of companies and
need to be reviewed. There is a need for a neutral policy regarding small and medium enterprises towards corporations
and for companies with majority foreign capital compared to Romanian capital companies
Assessment of the chemical and microbiological quality of the game meat for family consumption
No full textWild game meat consumption is usually consumed in the families of hunters, without any professional postmortem inspection performed by an official veterinarian. Because of that, the hygienic quality of this type of meat is unknown and the consumers choose to prepare at home these product by application of boiling for couples of hours, in order to be sure that the meals are safe. Sometime, wild game meat is processed in meat products, like salami, sausages or pastrami, and not all the time heat treatment is used. Hence, the hygienic quality, and especially microbiological quality is very important, in order to protect the health status of consumers. The aim of this study was to assess the chemical and microbiological quality of wild game meat intended for family consumption. During November 2017 – May 2018, 20 samples were collected from different species: deer, roe deer, wild boar and bear. The samples were collected three different hunting areas, located in Maramureş and Bistriţa County. All the samples were analyzed for chemical composition using FoodScan equipment: moisture, protein, fat, and collagen. Aerobic plate count, Enterobacteriaceae, and E. coli were analyzed using standardized methods. Chemical composition of game meat is characterized by a lower fat and moisture content, and a higher protein value when compared with farm animals. The highest protein content was recorded in the case of bear and the lowest in case of roe dear meat The lowest values of the fat was found for deer and the highest in case of bear meat. The presence of germs belonging to the Enterobacteriaceae family and E. coli demonstrates non-compliance with hygiene rules during the skinning, evisceration process. Although microbial load has been much higher in comparison with farm animals, we consider these values to be acceptable given the conditions of processing wild game meat (lack of hygiene conditions during processing and abuse transport temperature to the consumer's home in warm seasons). Game meat is considered to be a high-quality product, which can represent an increase food source alternative, because of its high nutritional value and the consumer's interest in healthier products in terms of the absence of chemical residues
