Opis:
Background: The entry and dispersal of modern humans is India of remains unclear and extending with many interesting evidences South India, assumed to be a major corridor for their with many ancient genetic deposits such as Dravidian tribal with Negrito features. As the relationships between the genetic polymorphs and diseases in human being revealed globally, it is worthy to investigate the genomic architecture of population in south India. Objective: To examine what evolutionary forces have most significantly impacted south Indian tribal genetic variation, and to test whether the phenotypic similarities of some south Indian tribal groups to Africans represent a signature of close relationship to Africans or are due to convergence. Methods: Blood samples from 193 unrelated individuals of both sexes are drawn from the Dravidian tribal settlements of Tamil Nadu and Kerala. South India are genotyped for four Aluindel (Alu FXIIIB, Alu ACE, AluTA25 and Alu PLAT) allele profile by PCR genotyping method. Results: All loci are highly polymorphic and average heterozygositiesare substantial (range: 0.37-0.44). Genetic differentiation is high (Gst = 3.7%) in all the study populations.

Opis:
In the present study was Vibrio species from wild marine shrimp, Penaeus monodon and to study its effect on the probiotic feed supplemented organism, when artificially in infected. Biochemical changes during infection of Vibrio parahamolyticus was evaluated by studying the Superoxide dismutase activity and catalase activity after infection. The superoxide dismutase activity and catalase activity in hepatopancreas was estimated in prawns from all the three feed groups. There was significant variation in the SOD activity and catalase activity in all three groups, after 30 days of feeding, uniformly they recorded gain in the activity. The SOD activity was 2.65 in control animals, 5.8 in B. coagulans supplemented animals, and 4.4 in B. firmus supplemented animals and catalase activity was 15.8 in control animals, 29.0 in B. coagulans supplemented animals, and 26.3 in B. firmus supplemented animals. The presence of this B. coagulans and B. firmus could protect the aquatic animals against the infection by pathogenic bacteria and might be applied as good probiotics in aquaculture.

Opis:
In the present work the effect of nitrogen on WC9 alloy at various weight percentages was analyzed and tested for their microstructural and mechanical properties. The nitrogen was added at 0.05, 0.10, 0.15, 0.20 and 0.25 wt. % in the solid form as nitrided ferrochrome to WC9 alloy. The samples were heat treated by solution annealing process at a temperature of 1100°C for 5 hours to improve the austenitic formation. Microstructures and mechanical properties such as tensile strength, yield strength, hardness, % elongation and % reduction of WC9-N alloy were examined. It was observed that increasing nitrogen wt. % increases the mechanical properties. The obtained mechanical properties were compared with base WC9 and C12A grade steel, where it was found to be replacement for C12A grade steel at its composition at lower end. The material cost analysis for WC9-N and C12A grade steel was done and both were compared.

Opis:
The present review deals with parameters influencing the rice breakage during rice milling operations and the effect of rubber roll Sheller in rice husk removal process. The main objective of rice milling system is to remove the husk and bran layer to produce the white rice. In this process, rubber roll sheller is used to remove husk from the grains by friction process. If the rubber material is too soft, there may not be sufficient shear force to husk the paddy. Wear will be minimum for rubber material with high hardness but indeed it pronounce the breakage of rice. Hence, for efficient husking the rubber roll material should possess the balance of physico-mechanical properties. Rice breakage depends on several other parameters like the type of harvest, drying temperature, drying methods, physical characteristics of paddy, husking characteristics, paddy moisture content, rubber roller speed, rubber roll pressure, paddy feed rate and fissures. Rubber roll wear depends on the type of rubber material attached to the roller, feed rate, roller speed, pressure etc.
