BACKGROUND: Intimate partner violence (IPV) is an under-diagnosed public health problem affecting women with attendant negative bio-psycho-social ramifications, and unfortunately there is no universally agreed recommendation for routine hospital IPV screening currently AIM: This study was carried out to determine the prevalence of IPV among women and their perceptions towards screening SETTING: The study was carried out in a hospital in Southwest, Nigeria METHODS: The study was a descriptive, cross-sectional study of 347 consenting women. Respondents were recruited using systematic random sampling. Data were collected using questionnaire adapted from the World Health Organization's (WHO) Multi-Country Study Questionnaire on Women's Health and Domestic Violence against women. Descriptive and inferential statistics were used and a p-value < 5% was considered significant RESULTS: The prevalence of IPV among the sample was 71.2%. The most common IPV pattern was controlling behaviour (49.6%) while sexual violence (19.6%) was the least. The majority (85.0%) of the respondents agreed that routine IPV screening should be done for women while 96.5% believed that it would enable doctors to help identify victims. The belief that it will help physicians in making a correct diagnosis, shared by 10.7% of the respondents, was statistically significant (odd ratio [OR] = 2.592, 95% confidence interval [CI] = 1.180-5.694, p-value = 0.018). A total of 37 respondents (10.7%) were about three times more likely to have experienced IPV than others CONCLUSION: There was a high prevalence of IPV and the women are open to routine hospital IPV screening, with the belief that it will help physicians to make an accurate diagnosis of IPV CONTRIBUTION: This research was done by majority of family health specialists, in Nigeria, an African country. The focus of the research was distinctly with an African perspective, in the field of family medicine which has a public health implication and effect on the community

This study focussed on the work hardening behaviour and microstructure of austenitic manganese steel relative to premature failure of crusher jaws. Samples of sound and failed crusher jaws were taken, the change with depth from the working surface to the sample core was measured and their microstructures observed. The study revealed a sharp hardness gradient in the failed crusher jaws, and presence of large carbides at both the austenite grain boundaries and in the austenite matrix. The failure of crusher jaws was attributed to brittle fracture as a result of precipitates of carbides from the inability of precipitated carbides to absorb shock during impact working. Finally, we conclude that the failure occurred as a result of inadequate quenching operations during the manufacturing process that resulted in the formation of carbide precipitates which embrittle the austenitic manganese steel, reduce its ability to withstand shock and create a non uniform plastic flow as it is work hardening.
