Research on the effectiveness of silk glue removal with tartaric acid, optimizing temperature, time, and concentration. Tartaric acid helps remove glue effectively, increases dyeing ability, and reuse.

This article compares the effectiveness of silk glue removal (eri, tasar, mulberry) by traditional, ultrasonic and microwave methods. Soda ash, H2O2 and enzyme (papain) are the most effective.

The article studies the effect of citric acid on Bombyx mori silk. 30% citric acid removes sericin nearly 100%, reduces weight by 25.4%, and increases tensile strength (507 MPa).

Từ kết quả nghiên cứu và khảo sát thực tế, đề tài đã làm rõ thực trạng tổ chức công tác kế toán trong điều kiện ứng dụng hệ thống quản lý nguồn lực doanh nghiệp (ERP) tại Công ty TNHH SILK Việt Nam.

Rohida police station recovered an old sculpture, accidentally discovered from the cemetery of Bharja/Bhaja village. It is a broken bronze Buddhist Idol and very rare sculpture. It has exquisite Antique beauty with rust in red and corrosion in green.

In spiders soluble proteins are converted to form insoluble silk fibres, stronger than steel. The final fibre product has longbeen the subject of study;however, little is knownabout the conversion process in the silk-producing gland of the spider. Here we describe a study of the conversion of the soluble form of the major spider-silk protein, spidroin, directly extracted from the silk gland, to ab-sheet enriched stateusing circular dichroism(CD) spectroscopy.

Nacre organic matrix has been conventionally classified as both
water-soluble and
water-insoluble,basedonits solubility in aqueous solutions after decalcificationwith acid or EDTA. Some characteristics (aspartic acid-rich, silk-fibroin-like content) were specifically attributed to either one or the other. The comparative study on the technique of extraction (extraction with water alone vs. demineralization with EDTA) presented here, seems to reveal that this gen-erally accepted classification may need to be reconsidered....

Nongenomic action of an insect steroid hormone, 20-hy-droxyecdysone (20E), has been implicated in several 20E-dependent events including the programmed cell death of Bombyxanterior silk glands (ASGs), but no information is available for themodeof theaction.Weprovide evidence for a putative membrane receptor located in the plasma mem-brane of the ASGs. Membrane fractions prepared from the ASGs exhibit high binding activity to [ 3 H]ponasterone A (PonA). The membrane fractions did not contain conven-tional ecdysone receptor as revealedbyWesternblot analysis using antibody raised againstBombyxecdysone receptor A (EcR-A)....

Silk fibroin ofBombyx moriis secreted from the posterior silkgland (PSG) as a2.3-MDa elementaryunit, consistingof six sets of a disulfide-linked heavy chain (H-chain)–light chain (L-chain) heterodimer and one molecule of fibrohex-amerin (fhx)/P25. Fhx/P25, a glycoprotein, associates non-covalently with the H–L heterodimers. The elementary unit was found and purified from the endoplasmic reticulum (ER) extract of PSG cells.

1. mua cáp micro-usb nếu bạn có nhu cầu chép các tập tin từ máy tính vào kindle fire thì chắc chắn bạn cần phải có một sợi cáp giao tiếp qua cổng usb. lúc này, bạn sẽ phải mua thêm một sợi cáp giao tiếp theo chuẩn micro- usb vì amazon không bán kèm nó theo thiết bị. tuy nhiên, nếu bạn đã có một sợi cáp chuẩn micro-usb dùng cho điện thoại di động thì bạn cũng có thể tận dụng nó để dùng cho kindle fire. 2. sưu tập miễn phí bạn không có đủ tiền...

We used generalized two-dimensional NMR–NMR correlation to examine the effect of potassium ions on the conformation transition in silk fibroin to investigate the possibility that the fairly high K + ion content found in the distal end of silk-secreting ducts in the silkworms could have a bearing on natural formation of the silk fiber.
