Authors: Khatsaeva R M 
Published: January 2020

Abstract
Using morphology and light microscopy, this work shows the positive effect of application of hydroponically grown wheat and an aqueous solution of astragalus as biological food additives on the development of the digestive system: muscular and glandular stomachs in Texas Pharaoh quails (Coturnix). Quails were divided into two groups (control and experimental) of 60 heads each. During the study, both groups were subject to identical keeping and feeding conditions in accordance with the established standards. Hydroponically grown wheat and an aqueous solution of astragalus were added to the diet of the experimental quail group. The data analysis conducted for the control and experimental quail groups using histology, morphometry and light microscopy made it possible to identify common patterns of the organization and development of morphofunctional structures of muscular and glandular stomachs and special aspects expressed in their more intensive development in the experimental group. The research data show that the use of hydroponically grown wheat and a solution of astragalus as organic bioadditives for stimulating the growth and development of production traits in quails and other birds is safe and acceptable. The obtained research data are of both practical and theoretical importance in implementing food programs and ensuring their reliability.

The efficiency of the spring wheat production process depending on the seeding rate in the arid zone of Mongolia
Authors: Litvinova V S , Bopp V L , Kurachenko N L , Shmeleva Zh N 
Published: January 2020

Abstract
The paper presents the experience of assessing the efficiency of the spring wheat production process depending on the seeding rate in the arid zone of Mongolia. The research was conducted in 2017 at the experimental field of PROLOG SYSTEMS LLC (Mongolia). The experiment used different norms of wheat varieties Novosibirskaya 15. Arable chestnut soils for land use in PROLOG SYSTEMS LLC have the light granulometric composition, characterized by a shortage of productive moisture and a low level of potential fertility. Low availability of humus, alkaline reaction, very low availability of mobile phosphorus, low-exchange potassium significantly reduce the productivity of the company’s fields. The evaluation of wheat biometric indicators revealed the dependence of plant height, spikelets number in the ear and productive bushiness on the seeding rate. A lower seeding rate in the arid zone of Mongolia reduces species competition between plants before the bushiness phase, but increases it in later phases of plant development due to the increased productive bushiness. Also, crops of wheat varieties Novosibirskaya 15 in Mongolia with an optimal seeding rate of 140-180 kg/ha had more intensive growth, maximum yield and minimum lodging compared with a higher seeding rate of 210-230 kg/ha. The decrease in the seeding rate is permissible in hot and arid conditions of Mongolia, while the presence of productive moisture in the spring period will be a determining factor.

Effect of Starting Microstructure in High Speed Steel on the Grain Refinement Potency of Electropulsing Treatment
Authors: Zhang Jiatao , Hu Penglei , Li Xiongqi 
Published: January 2020

Abstract
High speed steels (HSSs) are widely used materials for tools production, which grab a third part of the global cutting tool market. Heat treatment is an indespensable process for the fabrication of HSS tools. Modifications of carbides and grain size of the matrix are two main aspects for the heat treatment of HSSs. In order to obtain better wear property, hardness or red hardness, modification of carbides attracts more researchers’ attention, but grain refinement benefits to the toughness and tool life. Compared with the grain refinement methods used for other steels, such as controlled rolling, available method for grain refinement of HSSs seems deficient. Our previous study provided a new method to produce ultrafine grained M2 steel, but the effect of the starting structures on the grain refinement potential of electropulsing treatment (EPT) was not involved. Results in this work show that the grain size can both be refined or even ultra-refined by EPT, whatever the difference in the starting structures. But the austenite transformation of the matrix was completed at lower peak temperature when using starting tempered structure. And the pre-tempered M2 samples have higher hardness than that obtained after heat treatment or EPT when using the starting annealed structures.

Published: January 2020

Abstract
In order to improve the corrosion resistance of hot-dip galvanized steel, experimental study developed a new trivalent chromium passivation film with high corrosion resistant. The preparation method of passivation coating with high corrosion resistant was that the CrO3 was reduced to trivalent chromium by sufficient organic compound with reduction, then added colloidal SiO2, the matter containing radical phosphate and other substances after reaction completely. The passivation coating did not contain hexavalent chromium, and can meet the requirement of RoHS directive, so the film on hot-dip galvanized steel after passivation was environment-friendly. After coated on the hot-dip galvanized steel, the coating could be fast drying at 100 °C about 10s to 20s. The film was uniform, and did not appear floating, falling and other abnormal phenomenon, so that the passivation coating had good coating performance. The passivation reaction of the new trivalent chromium coating on the hot-dip galvanized steel was compound processes of electrochemical reaction, precipitation reaction and physical deposition. The passivation film produced no corrosion basically after 120h in the neutral salt spray test according to the Chinese national standards GB/T10125 and corroded area is less than 5% after 216 h, thus the corrosion resistance of the passivation film was excellent. In addition, the film has excellent heat resistance and fingerprint resistance, so it can meet the requirements of the user.

Study on a New Measurement Method of Small Polarization Rotation Using the Common-Path Heterodyne Interferometry and a Half-Wave Plate
Authors: Chiu Ming-Hung , Tsai Chih-Ting 
Published: January 2020

Abstract
This thesis proposes a novel method for small polarization rotation measurement using a half-wave plate and a high-stability common-path heterodyne interferometry. The phase with azimuth angle 22.5° of a half-wave plate has a distinct change resulting from the small polarization rotation of the incident light. The optical rotation properties of a material, such as glucose solution, can be determined in this phase from the concentration of the solution. Finally, the phase can be measured using a lock-in amplifier, and the relevant formula between the glucose concentration and the polarization rotation can also be identified with a recording table.
