A [2]rotaxane, in which the peptidic axle is protected from degradation by the macrocyclic sheath and terminated with a novel glycosidase-cleavable stopper, is rendered water-soluble by derivatisation with tetra(ethylene glycol) (TetEG) or glucosylated tetra(ethylene glycol) (Glc-TetEG) chains using the CuAAC 'click' reaction. The Glc-TetEG-derivatised rotaxane propeptide is >50 000 times more ...

Survivable systems—that is, systems that can continue to provide service despite failures, intrusions, and other threats—are increasingly needed in a wide variety of civilian and military application areas. As a step toward realizing such systems, this paper advocates the use of redundancy and adaptation to build survivable services that can provide core functionality for implementing survivabi...

In this study, Functionalized chitosan with amine groups was synthesized and coated on the surface of carbon black. The hybrid amino functionalized chitosan-carbon support was employed as an efficient, environmentally friendly heterogeneous catalyst for the transesterification reaction of canola oil and methanol. It was observed that this hybrid was more active than parent polymer at the reaction...

Growing cells of a filamentous mutant of a yeast, Candida albicans, were found to accumulate and reduce tetrazolium dyes whereas cells of the parent strain, growing as a normally budding yeast, accumulated the dye but did not reduce it. In older cultures, in which rapidly metabolizable carbohydrate has been depleted, the parent strain characteristically produces filaments. These cells, growing ...

The parent–provider relationship has been purported to be a central mechanism by which home-based parenting education and family support programs affect child and family outcomes. Despite its centrality in the theory of such programs, we have limited knowledge of how this relationship develops and functions, and how it may influence program outcomes. This article describes three levels of exami...

What is the effect of the AFDC-Unemployed Parent (UP) program on two-parent families? This question has become particularly relevant following the passage of the Family Support Act (FSA) of 1988, effective October 1990, which extended the previously state-optional AFDC-Unemployed Parent program to all states. This study clarifies what is meant by "two-parent" family in the federal legislation a...
