Objective of research: The study of features of epizootic process of monieziasis and mixed helminthiasis in sheep of Tajikistan. Materials and methods: Research was conducted in different sheep farms including Β«CharvozorΒ» of Vakhsh region, Β«DangharaΒ» of Danghara region, Β«ChorubkulΒ» of Temurmaliksk region and other private farms in 2015-2017. Fecal samples from 548 lambs, 636 from young and 717 from adult sheep were investigated in different months using Fuelleborni method of flotation, and Berman technique for the diagnosis of dictyocaulosis. The research results were statistically processed. Results and discussion: Significant differences in seasonal dynamics of monieziasis in sheep caused by Moniezia expansa and Π. Benedeni as well as dependence of the infestation of different Moniezia species on the age of animals was determined. In monieziasis occurring in spring and summer seasons (causative agent M. expansa) lambs become infected in May, the peak of infection falls on July. Towards autumn, a decrease in infection was observed, and in winter M. expansa rarely found. Adult sheep were mostly infected with M. benedeni, and in lambs this infection was found in July-August; the maximum level of infection was observed in March of the following year. M. benedeni remained viable in lambs within 10-12 months in regular superinfections (September-October) during the whole winter season. At the beginning of spring, spontaneous discharge of moniezia from sheep body occured. Monieziasis (M. expansa) in a severe form + dictyocaulosis as well as monieziasis+ hemonhosis+nematodirosis+ strongyloidosis at different combinations of components of parasitic cenosis occur in lambs of 2,5 to 6 months of age. Two and three-component infections are most common in sheep from joint-stock and individual sheep farms of piedmont and mountain region of Tajikistan.Π¦Π΅Π»Ρ ΠΈΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½ΠΈΠΉ - ΠΈΠ·ΡΡΠΈΡΡ ΠΎΡΠΎΠ±Π΅Π½Π½ΠΎΡΡΠΈ ΡΠΏΠΈΠ·ΠΎΠΎΡΠΈΡΠ΅ΡΠΊΠΎΠ³ΠΎ ΠΏΡΠΎΡΠ΅ΡΡΠ° ΠΏΡΠΈ ΠΌΠΎΠ½ΠΈΠ΅Π·ΠΈΠΎΠ·Π΅ ΠΈ ΡΠΌΠ΅ΡΠ°Π½Π½ΡΡ

Combination machine for soil preparation and sowing of gourds
The purpose of the study is to substantiate the method and design scheme of a combined machine for preparing the soil and sowing melons. The authors propose a new method of soil preparation and sowing, as well as a machine for its implementation. The basic principles and methods of classical mechanics, mathematical analysis, and statistics were used in this study. The method of preparing the soil and planting gourds provides a combination of the following technological processes: the turnover of the layers of the upper layer of soil, the sowing area to the left and to the right, shallow tilling the soil of the field with the left and right sides of the sowing area, deep tillage seeding areas with simultaneous formation of irrigation furrows and the local application of fertilizers, soil preparation for sowing in line sowing and sowing seeds of melons. The machine consists of lister housings installed along the axis of symmetry of the unit, flat cutters, parallel-type deep-diggers, furrowers, coulters for fertilizing, and a sowing device. It was found that preparation of soil for sowing and planting of melons with a minimum expenditure of energy is provided by the width of Lusternik buildings 86 cm, the width of tillers and cultivators, respectively, 45 and 33 cm, the longitudinal distance between the body and the plane of 35 cm between the cultivators of 42.3 cm, and longitudinal spacing of the chisel cultivator and sowing device 110 cm
Parameters of slitter for embedding manure in soil for melon crops
The purpose of the study is the theoretical justification of the parameters of the slitter for embedding manure in the soil. A slitter has been developed for lifting the formation, forming a gap along the manure strip lying on the field's surface, pushing it into the gap, and leveling the gap with soil. The basic principles and methods of classical mechanics, mathematical analysis, and statistics were used in this study. The slitter includes a rack, large and small cheeks connected to a soil-supporting plate with an increasing slope from the bottom to the top towards the small cheek and adjacent to the soil-supporting plate. A window is made in the big cheek for the passage of manure. The large cheek is somewhat pushed forward relative to the soil-bearing plate, and its front face is pointed. It is established that when planting fertilizers, the following operations must be carried out: lifting the formation, forming a gap along the manure strip lying on the field's surface, pushing the latter into the gap, and leveling the gap with soil. The working bodies of the dump type are the most acceptable for lifting the formation and the formation of a gap. The following optimal values of the parameters of the slitter are established: the removal of the large cheek is 710 mm, the width is 200 mm, the length and height of the window are 550 and 250 mm, respectively, and the angle between the forming and field edge in the horizontal plane is 42Β°, the height of the small and large cheeks of the slitter is 300 and 250 mm, respectively
Traction resistance of the combined machine plough
Subsoils are widely used on tillage and combination machines. The tiller of the combined machine for preparing the soil for sowing melons and gourds carries out strip loosening of the subsoil layers. The study aims to theoretically determine the traction resistance of a soil deepener of a combined machine for preparing the soil for sowing melons and gourds. The study uses the basic provisions of mathematics, theoretical mechanics, and agricultural mechanics. In studies, it is assumed that the destruction of the soil under the influence of the drill bit occurs by separation. The total traction resistance of the subsoiler was determined as the sum of the resistance of the rack and the bit. An analytical expression has been obtained to determine the traction resistance of a tilting machine with an inclined stand, depending on its design, technological parameters, and the physical and mechanical properties of the soil. As a result of theoretical studies, it was found that the traction resistance of the soil deepener is mainly influenced by its design parameters, the depth of soil cultivation, the physical and mechanical properties of the soil, and the speed of the machine
Propagation of Chlorella Vulgaris and Scenedesmus Obliquus in Dengizkul Lake and determination of protein content in them
The relative differentiation of the protein content in green algae grown in the contours of the Dengizkul reservoir was due to the fact that the level of mineralization of the water of the contours was low at the entrances(mouth) of the lake and high at the contours remote from it. Therefore, when growing green algae with a high protein content of Π‘hlorella vulgaris Beijer. and Scenedesmus obliquus (Turp.) KΓΌtz., the most optimal nutrient medium is the variant in which the juice of poultry manure is mixed with 1,2,3 g / l of water. The recommendations on the breeding of Π‘hlorella vulgaris Beijer. and Scenedesmus obliquus (Turp.) KΓΌtz. suspension grown in pools in semi-productive conditions by feeding fish Hypophthalmichthys molitrix are scientifically substantiated
Techniques of Primary Weapon Making
This article analyzes many theories that explain anthropogenesis state that an important aspect of human life is related to the making of weapons. And also the human ancestor created the first stone tools by chance, in accordance with the requirements of the biological instinct.
In this way, man, that is, a member of society, was not a single type, but in several forms. Some of them, from eating small species to fearing death, spontaneously, in accordance with the demands of biological instinct, used the relevant part of the brain unexpectedly and jumped ahead of others as their psyche developed
