Abstract. A mathematical model called BUOYANT has previously been developed for the evaluation of the dispersion of positively buoyant plumes originating from major warehouse fires. The model addresses the variations of the cross-plume integrated properties of a rising plume in a vertically varying atmosphere and the atmospheric dispersion after the plume rise regime. We have described in this article an extension of the BUOYANT model to include a detailed treatment of the early evolution of the fire plumes, before the plume rise and atmospheric dispersion regimes. The model input and output consist of selected characteristics of forest or pool fires, and the properties of a source term for the plume rise module, respectively. The main model structure of this source term model is based on the differential equations for low-momentum releases of buoyant material, which govern the evolution of the plume radius, velocity and density differences. The model is also partially based on various experimental results on fire plumes. We have evaluated the refined BUOYANT model by comparing the model predictions against the experimental field-scale data of the Prescribed Fire Combustion and Atmospheric Dynamics Research Experiment, RxCADRE. The predicted concentrations of CO2 agreed fairly well with the aircraft measurements conducted in the RxCADRE campaign. We have also compiled an operational version of the model. The operational model can be used for emergency contingency planning and for the training of emergency personnel, in case of major forest and pool fires.

Background: Weeds are one of major threats to crop yield and quality. Weeds compete with cane crop and reduce the yield significantly in a very short period. Planned use of all available farm resources leads to integrated control strategy. The current study aimed to study the use of inter row rotary weeder for integrated weeds management to control population dynamics of weeds in sugarcane crop. The objective of experiment is to find out economical, feasible and easy to use approach to minimize the weed density below the threshold level in sugarcane crop and to minimize the use of chemicals for weeds control to promote organic farming. Method: In this research experiment, at Sugarcane Research Institute, Faisalabad during 2017 and 2018, the treatment includes viz. Application od Click (atrazine and acetochlor) @ 3.75 Liter per hectare as Pre-emergence, Ametryn + Atrazine 80 W.P @ 2.50 kg per hectare as post-emergence, Machanical Inter-culture with Rotary weeder and cultivator plough and earthing up. These treatments in different combinations were compared with control. Results: The application of Pre-emergence weedicide Click (atrazine and acetochlor) @ 3.75 Liter per hectare + Inter culture with Rotary weeder 50 days after planting (DAP) + Inter culture with cultivator plough before earthing up (100 DAP) produced significantly higher cane yield of 105 t. ha-1 and highest net benefits per hectare of Rs. 156250/-. The lowest cane yield of 70 t. ha-1 was noted from the experimental units with Weedy check / control. If farmers use this approach, the use of post emergence weedicides will be minimized and will encourage organic farming with safe and healthy environment.

In this paper present the results of research of influence of the preparation «Kvatronan-Se» and carboxylates of Se, Cu, Mn, Cr, Ge in different combinations on haematological parameters of blood of experimental animals. Study was carried out on the basis of PC Haleks-Agro. It is located in the village Gul'sk of Novograd Volynskiy district of Zhytomyr region. In the farm to bred of Simmental cows. For the experiment was formed four groups. We took into account age, live weight of 650–700 kg and the average milk yield 5000–6000 kg. Animals is located in identical conditions of feeding and maintenance. Research experiment was carried out on animals couples counterparts.  Preparations introduced animals three times at 10–12 days after insemination. The cows first experimental group were injected complex nanokarboksylativ Ge, Cu, Mn and Cr, second – drug Kvatronan–Se and animals third experimental group was administered a complex composed of Se, Cu, Mn, Cr. On 13 day after insemination in experimental animals were taken blood from tail vein and examined the contents of hematological parameters. Established that injection nanokarboksylativ enhance the fertility of cows in the first and third group, the figure rose to 20% in the second by 40% compared with the control. Research hematological parameters blood  animals shows that after entering content drugs of blood cells had minor changes but remained within the physiological norm. The results show that in  concentration monocyte the second group  was at 5.53% (P > 0.01) higher compared to the control group and 2.3% compared to the first and third. The content of lymphocytes in this group decreased by 26.3% (P > 0.05), 22% and 16% relative to the control, the first and third groups. Also, it should be noted that the hemoglobin in the experimental groups decreased in group I by 7.9% in the II – 3.9% and III by 7.3% compared with the control group. Also, these groups distinguished downward trend eosinophils 1.8%, 1.5%, 2.05%. Then, as the number of segment-nuclear neutrophils contrast, in the first group increased by 18.2% in the second and third at 16.9% comparatively control. The number of monocytes in the second group doslfidniy the suspicion was higher by 66.3% and 0.3% higher than the physiological norm – it may indicate a high immune response.
