One of the most economic exploitation, widely cultivated, and financially viable non-mulberry silkworms is eri silkworm (Philosamia ricini). The feeds that consume have a significant impact on their yield silk production. A study was conducted to assess growth characteristics eco races in circumstances western region Tamil Nadu. Central Muga Eri Research Institute Jorhat, Assam provided silkwor...

Antheraea mylitta produces tasar silk and is an endemic species of the Indian subcontinent. Populations of this species show a certain degree of phenotypic variability for which they are designated as ‘ecoraces’. Inorder to study the genetic variability in relation to the environment among Daba T.V and Andhra local the life history of two ecorace from hatching to egg laying stage and the cocoon...

In the current era of highly developed science, technology and technology, demand for natural fabrics is increasing year by in world market, silk industry science are led to cultivation mulberry varieties with high nutritional value creation breeds hybrids suitable different seasons changing external environment. recent years, Republic Uzbekistan, practice rearing silkworms several times a has ...

the present study was conducted to estimate correlations among performance and egg quality traits in iranian native fowl. data were collected from 21,679 birdsat the isfahan native fowl breeding center to derive genetic parameters for performance traits and egg quality traits were measured on eggs of 1,020 birds. genetic correlations of performance and egg quality traits were estimated with a b...

Evidence is mounting that recent multiwavelength detections of fast blue optical transients (FBOTs) in star-forming galaxies comprise a new class transients, whose origin yet to be understood. We show hydrogen-rich collapsing stars launch relativistic jets near the central engine can naturally explain entire set FBOT observables. The jet-star interaction forms mildly-relativistic shocked jet (i...

Silk consists of two types of proteins, silk fibroin and sericin. Sericin contributes about 20-30 per cent of total cocoon weight. It is characterized by its high content of serine and 18 amino acids, including essential amino acids. There are different methods of isolation of sericin from silk thread. Solubility, molecular weight, and gelling properties of sericin depend on the method of isola...

This study was carried out on 11 Chinese and 12 Japanese silkworm strains maintained by the Center for the Technological Development of Sericulture (CDTS) germplasm bank, located in Pereira, Colombia. The goals were to determine the genetic population structure of the two groups and the association between molecular markers (AFLPs) and important productivity characters. Group analysis showed th...

A high-density genetic map is essential for quantitative trait locus (QTL) fine mapping. In this study, 4,508 effective single nucleotide polymorphism markers (detected using specific-locus amplified fragment sequencing) and 475 microsatellites were mapped to 19 linkage groups (LGs) using a family with 157 individuals. The map spanned 2,713 cM, with an average of 259 markers and 79 loci per LG ...

In this paper, an elastic shell model is presented for postbuckling prediction of a long thinwalledcylindrical shell under axial compression. The Ritz method is applied to solve the governingequilibrium equation of a cylindrical shell model based on the von-Karman type nonlinear differentialequations. The postbuckling equilibrium path is obtained using the energy method for a long thin-walledcy...
