One and twosoliton solution of the scalar nonlinear Schrodinger equation with selfconsistent potentials 
Using algebraicgeometric method for integrating of nonlinear differential equations one and twosoliton solutions SNSE with selfconsistent potentials YajimaOikawa are obtained and studied. These solitons similarly to the SG breathers have a binding energy. Binding energies are calculated for specific values of the spectral data. Studies have shown that for a given SNSE selfconsistent potentials both onesoliton and twosoliton regular solutions exist.

An influence of reaction rate for hydrolysisextraction of sunflower baskets at the dynamic mode 
There was studied interconnection of dividing the yields and monosaccharide composition the protopectin (PP) of sunflower basket (SB) microgel (MG) pectin compounds (PC) and oligosaccharides(OS) regarding speed of stream the hydrolyzing solution from 3 to 6 mL/min in directflow extraction column at the condition of dynamic mode (DM). There is illustrated that by increasing of speed of stream occurs wellproportionated growth the contents of all components the reaction of decomposition reaction PPMG, SB and OS. The contents of main components MG and PC are very close inter se, but total content these products depending on flow rate runs up to 2030 per cents, which it is considerably more than that yields of pectin polysaccharides obtaining by the other conditions of reaction, by statistic conditions(SC). The management of flow rate promotes direct decomposition reaction of PP to predominantly direction of obtaining the MG or PC with high containing remainders the galacturonic acid.

Kinetics of chloride acid decomposition of kaolinic clays of ChashmaSang deposit of Republic of Tajikistan 
The kinetics of the hydrochloric acid decomposition of kaolin clay of ChashmaSang deposit of the Republic of Tajikistan was studied. The numerical value of the activation energy is identified, which was 33.56 kJ/mole for FeO at temperatures from 20 to 40°C, and 17.14 kJ/mole at temperatures from 60 to 98°C and these values indicate that from 20 to 40°С in the mixed area, and depending on 60 to 98°С process proceeding at diffusion area. The apparent activation energy of the process of decomposition of kaolin clay with hydrochloric acid was calculated by the Arrhenius equation, which was 33.84 kJ /mole for AlOat temperatures from 20 to 60°C, and at the temperature range of 80 to 98°C was 30.36 kJ/mole. The numerical value of the activation energy indicates the proceeding of the process in the mixed, close to the diffusion area.

In this paper the results an analysis of specific leaf weight (SLW) of long stable cotton with limit types of stem branching after defoliation are given. Is shown that the man made of defoliation in the squaring phase reduced of SLW in retain upper and lower storey of leaves. In the flowering phase the defoliation cause the increase of SLW upper of leaves SLW, but in the lower of leaves SLW is decrease.
