The effect of a juvenile hormone (JH) mimic R394 (ethyl 9-cyclohexyl-3, 7-dimethy l-2, 4-nonadienoate) applied topically on the abdominal tergum of silkworm (Bombyx mori L.) after the fourth ecdysis has been studied. JH R394 ranging from 1.0, 0.1, 0.01 μl / larva was applied at 48, 72 and 96 hours of V instar larva that was improved the cocoon weight, shell weight and shell ratio etc. The most ...

a bivoltine silkworm hybrid, ka x nb4d2 was treated with the juvenoid r394 (ethyl-9 cyclohexyl-3,7-dimethyl-2,4-nonadienoate) at a dose of 0.039 nl/larva at 24, 48, 72 and 96 h of 5th instar for silk yield improvement. treatment specific significant increase was observed in the cocoon and shell weight with no such marked variation in the shell percentage. notable changes were also seen in trait...

Hepatitis C virus (HCV) is a worldwide health problem with high morbidity and mortality. HCV polymerase is an attractive target for the development of antiviral strategies. The aim of the present study was to report the sequence variation in the HCV NS5B gene from genotype 3 patient samples. The gene was amplified, cloned and sequenced. A nucleotide and amino acid sequence comparison of conserv...

This work presents ultrasound-assisted dispersive micro solid phase extraction (USA DMSPE) for preconcentration of fluorine (F) in water and herb samples. TiO2 nanoparticles (NPs) were used as an adsorbent. The determination with slurry sampling was performed via molecular absorption of calcium monofluoride (CaF) at 606.440 nm using a high-resolution continuum source electrothermal absorption s...

Several theoretical and experimental studies have shown that organic dyes may show solvatochromic reversal in the visible region with respect to the solvent polarity. This controversial non-monotonic behavior is still not well understood. This has been analyzed here using the merocyanine of Brooker as the working example. Sometimes the solvatochromic reversal is attributed to self-aggregation.[...
