PURPOSE To examine the demographic, sociocultural and socioeconomic factors that prevent families of cataract blind children from accepting free pediatric cataract surgery in Malawi. METHODS A total 58 parents of 62 children were recruited into the study. Of these, 53 parents partook in in-depth interviews and focus group discussions after the children were screened and the parents offered fr...

BACKGROUND Randomised controlled trials (RCTs) often fail to recruit sufficient participants, despite altruism being cited as their motivation. Previous investigations of factors influencing participation decisions have been methodologically limited. This study evaluated how women weigh up different motivations after initially expressing altruism, and explored their understanding of a trial and...

Ugi adducts derived from aromatic aldehydes may be converted to pyrrolines via addition of Michael acceptors under microwave irradiation. The reaction may proceed via unusual formation of azomethine ylides followed by a [3+2] cycloaddition using Michael acceptors.

This review provides a current status report of the various n-type polymer acceptors for use as active materials in organic photovoltaic cells (OPVs). The polymer acceptors are divided into four categories. The first section of this review focuses on rylene diimide-based polymers, including perylene diimide, naphthalene diimide, and dithienocoronene diimide-based polymers. The high electron mob...

Articles you may be interested in Origin of subgap states in amorphous In-Ga-Zn-O A pathway to p-type wide-band-gap semiconductors Appl. We examine how hole localization limits the effectiveness of substitutional acceptors in oxide and nitride semiconductors and explain why p-type doping of these materials has proven so difficult. Using hybrid density functional calculations, we find that anion...

1. The choline dehydrogenase (EC 1.1.99.1) WAS SOLUBILIZED FROM ACETONE-DRIED POWDERS OF RAT LIVER MITOCHONDRIA BY TREATMENT WITH Naja naja venom. 2. The kinetics of the reaction of enzyme with phenazine methosulphate and ubiquinone-2 as electron acceptors were investigated. 3. With both electron acceptors the reaction mechanism appears to involve a free, modified-enzyme intermediate. 4. With s...

Data from a survey of 200 Billings Ovulation Method acceptors in Korea were used to describe a profile of these natural family planning acceptors, and to calculate use effectiveness rates for twelve months of use among women using the method for avoiding an unplanned pregnancy. The majority of acceptors were women of proven fertility who wanted to limit their family size, and many of them (79%)...
