Genetic Characteristics of Holstein Cattle Reared in the Far East

Abstract—Blood group surveys in the Holstein cattle bred reared in the Far East Federal okrug have been carried out. The antigen composition of blood groups among 6009 animals of four populations in Khabarovsk krai, Primorsky krai, Sakhalin oblast, and Amur oblast was determined. The analysis of distribution of the antigen-specific factors was performed. It has revealed both the high frequencies of antigens A2, G2, G3, Y2, $$E_{2}^{'}$$ , $$E_{3}^{'}$$ , Q', C1, C2, E, W, X2, F, J, and H' and the low frequencies of antigens Z', T2, B', I', P', Y', B'', M, U'', and H'' in all the populations. The analysis of the EAF-locus genotype distribution has revealed disturbances in the genetic equilibrium among the Holstein cattle in Sakhalin oblast, Khabarovsk krai, and Primorsky krai. High levels of genetic similarities among the populations in Primorsky krai and Sakhalin oblast are determined. They are caused by the use of similar genetic materials in order to build up the herds. The Holstein population in Khabarovsk krai has the highest level of genetic diversity, which can be associated with the conditions of its generating and the methods of breeding. The obtained results can serve as the tools for developing the projective methods for animal breeding and designing the pedigree worksheets.

Phytochemical study of phenolic compounds of labrador tea (Lédum palústre L.)

Aim. This work is devoted a phytochemical study of biologically active substances in herb of Labrador Tea (Ledum palustre L.), as well as investigation of the possibility of complex use of raw materials in order to create on its basis new herbal medicines. Methods . The object of the study served as the herb Labrador Tea. Separation of isolated substances was performed by adsorption and partition chromatography on various adsorbents. The structure of the isolated compounds was determined based on physicochemical methods: paper (PC) and the thin layer (TLC) chromatography, UV, IR and NMR spectroscopy in comparison with the original valid standards of flavonoids. Acid hydrolys was used for the determination of the flavonoid aglycone composition. The content of total flavonoids was determined by differential spectrophotometry at a wavelength of 412 nm from the reaction with aluminum chloride based on the hyperoside-standard ( Ukrainian scientific Pharmacopoeial center for quality of medicines (Pharmacopoeial center) , Kharkоv). Results . During this study we found more than 40 of phenolic compounds and identified 31compounds. The phytochemical analysis showed the presence of flavonols (11 compounds), catechins (5). Hydroxycinnamic acids represented by caffeic, ferulic, chlorogenic acids. Besides that, it were found phenolic glycoside arbutin, coumarins - coumarin, umbelliferon, scopoletin, esculetin and esculin, tannins – metyl gallate, pyrogallol. Conclusions . The following biologically active substances were defined for the first time: flavonoids – 5-methyl-kaempferol, avicularin, polistahozid, quercitrin; coumarins – esculetin, esculin; as well as hydroxycinnamic acids – ferulic, chlorogenic, neochlorogenic of Labrador Tea. The obtained data justify the prospectivefor creation of new and effective herbal medicines from Labrador Tea

Power Generation Using Piezoelectric Material

In last few years low power electronic devices have been increased rapidly. The devices are used in a large number to comfort our daily lives. With the increase in energy consumption of these portable electronic devices, the concept of harvesting alternative renewable energy in human surroundings arise a new interest among us. In this project I try to develop a piezoelectric generator. That can produce energy from vibration and pressure available on some other term (like people walking ). This project describes the use of piezoelectric materials in order to harvest energy from people walking vibration for generating and accumulating the energy. This concept is also applicable to some large vibration sources which can find from nature. This project also represents a footstep of piezoelectric energy harvesting model which is cost effective and easy to implement.
