EMCCDs for space applications

This paper describes a qualification programme for Electron-Multiplication Charge Coupled Devices (EMCCDs) for use in space applications. While the presented results are generally applicable, the programme was carried out in the context of CCD development for the Radial Velocity Spectrometer (RVS) instrument on the European Space Agency's cornerstone Gaia mission. We discuss the issues of device radiation tolerance, charge transfer efficiency at low signal levels and life time effects on the electron-multiplication gain. The development of EMCCD technology to allow operation at longer wavelengths using high resistivity silicon, and the cryogenic characterisation of EMCCDs are also described

'GR 7' Grape

'GR 7' is an early / mid-season red wine grape for use primarily in red wine blends. It is distinguished from other red wine grapes grown in cool climates by its high degree of winter hardiness, adaptation to mechanized production systems, and ability to survive in older plantings where other red wine grapes are lost due to tomato and tobacco ringspot virus infections. ?GR 7? is a highly productive, easy to manage cultivar, and is the sixth wine grape to be developed by the New York State Agricultural Experiment Station of Cornell University

Harnessing the senga institution of adolescent sex education for the control of HIV and STDs in rural Uganda.

Senga (father's sister) is a traditional channel of communication about sexual behaviour for adolescent females in rural Uganda. We evaluated a modification of this approach as an intervention for HIV and STDs in a pilot study in two intervention villages and one control village over 12 months. Eleven adult women and three adolescent girls were chosen and trained to become sengas. Adolescent girls were encouraged to visit the sengas for sexual health information. Adult sengas saw an average of 21 clients; adolescent sengas saw five. Adolescent girls made 45% of visits. The expected reasons for attending the sengas accounted for 51% of visits. Knowledge about HIV/AIDS, sexual communication skills, consistent condom use and family planning service use increased in the intervention group of girls over the study period and compared to control girls. Symptomatic STDs decreased in the intervention group. This intervention was readily accepted by the community; members of all ages and both sexes attended for a wider variety of reasons than anticipated. Adolescent girls in the intervention group showed improved knowledge, attitudes and practices related to HIV and STDs. This promising intervention warrants further testing in larger studies and other settings

Mobility, sexual networks and exchange among bodabodamen in southwest Uganda

In order to examine the sexual behaviour of a highly mobile social-group, qualitative data and quantitative data were elicited from 212 private motorbike taxi-men, locally called bodabodemen, from two study sites in Masaka, Uganda. Selection criteria were availability and willingness to participate ill the study. Research techniques employed were a questionnaire, focus group discussions, in-depth interviews and case studies. Findings indicate that bodabodamen are a highly mobile group who engage in frequent seasonal rural-urban migration. Consequent to this, bodabodamen have a wide network of both occasional and regular sexual partnerships. Both serial and concurrent multiple partnerships are with adults, youths, widows, students, sugar-mummies, barmaids, commercial sex workers, tailors. Exchange plays a significant role in sexual negotiations but the act of giving to a sexual partner is ambivalent in its social interpretation. Since bodabodamen have regular access to cash, they have higher bargaining power for sex. Implications for HIV/ AIDS prevention are discussed

Remaily Seedless Grape

Since the late 19th century when grape breeding began at the New York State Agricultural Experiment Station, a major goal has been to combine certain fruit attributes such as seedlessness, crisp texture, and adherent skin of Vitis vinifera L. table grapes with some of the vegetative characters such as disease resistance and cold hardiness of native American hybrid (V. labruscana, Bailey) grape cultivars

Attitudes to voluntary counselling and testing for HIV among pregnant women in rural south-west Uganda.

UNLABELLED: This paper describes the results of a study exploring the attitudes of women attending maternity clinics to voluntary counselling and testing during pregnancy in rural areas in south-west Uganda. It was a qualitative study using focus group discussions (FGDs). Twenty-four FGDs were carried out with 208 women attending maternity clinics in three sites in rural south-west Uganda. The FGDs were all recorded and transcribed, and analysed using standard computer-based qualitative techniques. Almost all women were willing in principle to take an HIV test in the event of pregnancy, and to reveal their HIV status to maternity staff. They were anxious, however, about confidentiality, and there was a widespread fear that maternity staff might refuse to assist them when the time came to deliver if their status were known. This applied more to traditional birth attendants than to biomedical health staff. There were also rumours about medical staff intentionally killing HIV-positive patients in order to stem the spread of the epidemic. Women were concerned that if their husbands found out they were HIV-positive they would be blamed and separation or domestic violence might result. IN CONCLUSION: although VCT during pregnancy is acceptable in principle, much will need to be done to ensure confidentiality and allay women's fears of stigmatisation and discrimination during delivery. Community sensitisation will be necessary and male partners will have to be involved if interventions are to be acceptable
