A case-control study of menstrual dysfunction occurring in women attending a general practice after tubal ligation
… This study was conducted to examine whether post-sterilisation menstrual dysfunction was measurable in a group of women attending a general practice, by means of a case-control study. Biopsychosocial factors, such as health status, social support, psychological and medical history, and reasons for …

Evaluating Mending Mamre: An Animal Welfare Intervention
… aim to improve animal welfare in different ways. Sterilisation is often the first step but is not enough. Consequently, education is often used in combination, to teach responsible pet care and ownership to pet owners. By increasing their understanding and knowledge of animals it is hoped that the …

Psychological and socio-cultural effects of forced and coerced sterilization of women living with HIV (WLHIV) in Namibia: Implications for intervention
The forced and coerced sterilisation of women living with HIV (WLHIV) is one of the serious forms of fundamental human rights violations, which has occurred, the world over. In Namibia, cases of forced and coerced sterilisation were first reported in 2007 to 2008. With the support of civil society …

Development and application of time-temperature integrators to thermal food processing
… of a few minutes at 70°C and one for full sterilisation of >3 minutes at 121.1°C. Examples are given of how these TTIs are applied to a variety of industrial thermal processes. These include traditional methods such as canning, but also more complex systems such as tubular heat exchangers …

Effects of sterilization, conditioning, and thermal aging on the retention of zirconia hybrid abutments
… of this study was to assess the impact of sterilisation, conditioning methods, and thermal ageing on the retention strength of two-piece zirconia abutments. A total of 128 stock zirconia abutments were divided into 4 groups, each including 32 abutments. The groups were categorized based on …

Studies on the micropropagation of carob : Ceratonia siliqua L.
… using axillary buds as explant material. Surface sterilisation and subsequent development of the buds was difficult to achieve due to the production of phenolic exudates by the explants, which were detrimental to plant health. The use of a pre-soak with an antioxidant (ascorbic acid) solution in …

Development and in-vitro evaluation of a potentially implantable fibre-optic glucose sensor probe
… radiation and their performance before and after sterilisation examined. The gamma sterilisation was found to cause a reduction in the range of the sensors,for example 0 to 24 m /I down to 0 to 14mM/l in one case. The affect of 24 hour operation in a 5mM/1 solution of glucose and storage, for up …
