ORGANIZATION OF MOTOR ACTIVITY OF YOUNGER SCHOOLCHILDREN WITH THE USE OF HEALTH-SAVING TECHNOLOGIES

The article says that children currently lack movement. In the course of the study, it was revealed that through simple measures it is possible to increase the motor activity of an entire class and if this is carried out regularly, to bring the indicators to the optimal norm. By interacting with parents, children can be motivated to a healthy lifestyle.

RESEARCH OF THE PROCESS OF DEFORMATION OF EXTRACTIONAL PHOSPHORIC ACID FROM PHOSPHORITES OF CENTRAL KYZYLKUM

The purpose of this research was to determine the optimal technological parameters for the purification of extraction phosphoric acid based on phosphorites of Central Kyzylkum from fluorine by precipitation with sodium salts. The influence of the norm of sodium silicate and the total norm of sodium carbonate and sodium metasilicate salts on the chemical composition and degree of precipitation of sodium silicofluoride was research. It is shown that the optimal norm of sodium metasilicate is the stoichiometric norm for binding fluorine present in the extraction phosphoric acid to silicofluoride and the total norm of sodium salts is 120-140%, the temperature is 70°C. Separation of the liquid and solid phases by settling is preferably carried out at a temperature of 30°C and a process duration of 120 minutes.

Зенкор Ультра, КС для защиты моркови

Приведены результаты исследований по оценке эффективности гербицидов на посевах моркови. Установлена оптимальная норма применения Зенкор Ультра, КС, его биологическая эффективность и безопасность использования. Зенкор Ультра, КС в оптимальной норме 0,5 л/га перспективен для применения на посевах моркови в фазу трех листьев, засоренных чувствительными к нему видами однолетних двудольных сорняков.The results of studies for assessment the effectiveness of herbicides on carrot crops are presented. The optimal norm of of Zencor Ultra, KS application, its biological efficiency and safety of use are ascertained. Zencor Ultra, KS at an optimal rate of 0.5 l/ha is promising for use on carrots in the phase of three leaves clogged with sensitive species of annual dicotyledonous weeds.
