To construct rapid C3H8 transport pathways in polymer matrix, alkyl chain-functionalized graphene oxide (GO) was prepared via grafting octadecylamine (ODA) molecules and then embedded into polydimethylsiloxane (PDMS) matrix to obtain high-efficiency mixed matrix membranes (MMMs). The incorporation of alkyl chains contributes to lowering the surface energy of GO nanosheets and providing higher a...

The translation strategy of carnation mottle virus (CarMV) in vitro has been generally assumed to involve internal initiation events on full-length, genomic RNA (4.3 kb). We suggest that this is, at least in part, incorrect. Encapsidated RNA, fractionated on denaturing sucrose gradients, or total RNA from CarMV-infected leaves, fractionated under non-denaturing conditions, was translated in an ...

1. The proteins of the groundnut cotyledon have been fractionated and analysed by DEAE-Sephadex chromatography and acrylamide-gel electrophoresis. Seventeen components were detected. 2. A new method is described for the preparation of arachin, using calcium precipitation. The product contains at least 99% of arachin. 3. The theory of acrylamide-gel electrophoresis is developed and applied to th...

The 2-oxoglutarate dehydrogenase multienzyme complex of Escherichia coli was treated with trypsin at pH 7.0 at 0 degrees C. Loss of the overall catalytic activity was accompanied by rapid cleavage of the lipoate succinyltransferase polypeptide chains, this apparent Mr falling from 50 000 to 36 000 as judged by sodium dodecyl sulphate/polyacrylamide-gel electrophoresis. A slower shortening of th...

In 2004, Zhang and Xiao proposed a multisignature scheme based on ElGamal discrete logarithm algorithm which allows a signer group to sign a signature and a verifier group to verify the validity of the signed signature. In this paper, we will show that any verifier in the verifier group can break their scheme by replacing the valid signed message with another forged one which will also be authe...

The mucoadhesive capacity of poly(2-hydroxyethyl methacrylate) (PHEMA) microspheres was studied in contact with Sprague-Dawley rat jejunum at pH = 6 and at 22°C. Dry PHEMA microparticles exhibited adequate mucoadhesive capacity, which was independent of nominal crosslinking ratio. When PHEMA microparticles were loaded with linear PEO chains of molecular weight 1000, the mucoadhesive capacity in...

Databases model parts of reality by containing data representing properties of real-world objects or concepts. Often, some of these properties are time-related. Thus, databases often contain data representing time-related information. However, as they may be produced by humans, such data or information may contain imperfections like uncertainties. An important purpose of databases is to allow t...

The Indian village has often been seen as the ultimate signifier of " authentic native life " , a place where one could see or observe the " real " India and develop an understanding of the way local people organised their social life. Though it was during the colonial period that the Indian society was first essentialised as a land of 'village republics', the later traditions of scholarship to...
