Description
Sunflower is one of the most important oilseed crops, which are of great economic importance in Russia and in the world. It is very adaptive crop in terms of climatic conditions range, for that reason it is cultivated on a vast territory of the Russian Federation in various weather conditions. Sunflower oil has high nutritional and taste qualities, it is used numerously in food and is applied in various fields of food industry. The biologically active linoleic acid, phosphatides and fat-soluble vitamins A, D, E and K, which are of great nutritional value to humans, are contained in the oil. According to its calorific capacity, sunflower oil is on the first place among vegetable oils. Due to biological characteristics of sunflower, the Krasnodar region is the most favorable region of the Russian Federation for obtaining high and stable yields of this crop. However, here the drought is observed during the summer period and it affects adversely the productivity and quality of sunflower seeds. The increasing of resistance to unfavorable weather conditions is possible only based on detailed study of physiological features of productivity formation and seeds quality that is highly important task in view of the current geopolitical situation in Russia. One way of solving this issue is the appliance of the growth regulators, possessing anti-stress activity that improve the quality of sowing seeds and increase the productivity and plant resistance to stressful environmental factors. These drugs include growth regulator called Furolan, which was created in KubGTU and is certified for use in Russia. It is not toxic and is used in nano-dozes, there is no its residual quantities in the products and environment. Furolan has a positive effect on physiological and biochemical processes, improves the productivity of plants, their resistance to unfavorable growing conditions by increasing the resistance to dehydration as well as to the risk of fungal diseases

Description
Nigeria has the largest oil sands and bitumen resources in Africa and is one of the main leading countries in the world from the point of view of its significant potential heavy oil deposits. Research of geological and physicochemical properties confirmed that the Nigerian bitumen is an important energy source and an alternative source of hydrocarbon feedstock for the petrochemical industry. Nigeria imports black oil for the petrochemical industry and its heavy oil can act in place of this black oil. In addition, researchers have successfully established the possibility of producing electrical energy from this heavy oil. Tar sands and bitumen are able to help improve the economy of Nigeria

Description
We have performed an experimental study of the evaporation process at a temperature of 105 ° C for the egg white model solution in distilled water to evaluate the ratio of the heat transfer coefficient from air to water ratio mass transfer to the water surface into the air by evaporation from the free surface in a forced convection. Evaporation of the solution was carried out in a Memmert oven of class Basic (Germany) equipped with forced air circulation, the control panel with a display and a temperature control device. To determine the surface temperature at which the main evaporation of water from the process solution, the experiment conducted under the same conditions by measuring the average temperature of the layer of water sample, placed in a Petri dish in an oven with a sensor - DMM Mastech M838 series. It is found that the coefficient of heat transfer from air to water almost a thousand times greater than the coefficient mass transfer from the water surface into the air

Description
Getting the maximum number of day-old chicks largely depends on the disinfection of hatching eggs. Disinfection of eggs is important in the complex of veterinary-sanitation activities carried out in poultry farms for the prevention and elimination of infectious disease in birds. The perspective of using ozone in the poultry industry is possible due to its advantages characterized in comparison with other chemicals. It was found that ozone has the special ability to retard the growth of fungi in the biological substrates, also slows the appearance of mold on the surface of the eggshell even at 90 % relative humidity. When making parameters and modes of electro-ozonation process of egg store poultry farms there were carried out experimental studies. After ozone disinfection of hatching eggs, total bacterial contamination of shell eggs decreased by 99.89 %. The relative error of the experimental values of the theoretical amount was 7 %. As a result of production tests we set quality parameters developed by the process of electroozonation egg store poultry farms: regulation time is 8 minutes, dynamic error is 0.9, overshoot rate is 4.5%, generalized integral RMS figure is 10.6 % . The findings suggest that there is a qualitative regulation of the distribution of ozone in the egg store

EFFICIENCY OF ROKSATSIN IN AEROSOL DISINFECTION OF THE LIVESTOCK BUILDINGS
DescriptionThe authors briefly describe the properties of polyhexamethyleneguanidine hydrochloride (PHMG), which refers to a broad-spectrum biocide and has antimicrobial activity against Gram-negative and Gram-positive bacteria, viruses and fungi. PHMG has a deodorizing effect, gives the treated surfaces long bactericidal effect, which can be stored depending on the surface and other external factors from 3 days to 8 months. The authors have presented data about the level of bacterial and fungal contamination of air in the dispensary before and after aerosol treatment of Roksatsin. Bacterial contamination of air dispensary determined via the sedimentation method (Koch Method), which is settling microflora (in air), under gravity, on the surface of a growth medium. For the determination of total bacteria and fungi in 1m3 of air the authors make calculations of total aerobic microbial count (TAMC) according to the formula that was proposed by V.L. Omelyanskii. Bacterial contamination of air was evaluated before disinfection. Accounting quality of aerosol disinfection performed by sedimentation microflora on Petri Dishes through 30, 60 and 120 minutes of exposition. In the analysis of the data the authors defined that Roksatsin as a disinfectant has a negative effect on pathogens, namely significantly reduced the content of pathogenic and conditionally pathogenic bacteria and fungi in the air, so it can be used for preventive and compelled aerosol disinfection of air in the livestock buildings
