Fabric filters are generally used to eliminate the particulate matter of flue gas that is generated from waste incinerators. The pressure drop of fabric filter (ΔP) is accompanied by the build-up of a dust layer on the fabric filter, and ΔP increase leads to an increase in the energy consumption of induced draft fan in an incineration facility. In this study, phosphoric acid (H3PO4) and monobasic calcium phosphate (Ca(H2PO4)2) are tested as chemicals to reduce ΔP in fabric filter using a laboratory-scale equipment. The phosphorus concentration of collected dust was correlated to the increment of ΔP per unit weight of dust deposited on the filter fabric. The effect on ΔP reduction was apparent at the phosphorus concentrations of 2.2-5.3 wt% in the collected dust. As a result, the gas permeability was enhanced by 2-6 times as compared to that was observed at phosphorus concentrations less than 0.6 wt%. Based on the result of XRD analysis of the dust sampled from the filer bag, it was concluded that H3PO4 reacted with the Ca compounds even though Ca-P compound could not be identified exactly. When H3PO4 was sprayed, dust particles grew in size and the surface roughness of dust layer increased too. Such changes in the physicochemical properties of dust seemed to enhance the gas permeability of the dust layer, which caused a reduction in the value of ΔP.Abortion is legal in South Africa, but negative abortion attitudes remain common and are poorly understood. We used nationally representative South African Social Attitudes Survey data to analyze abortion attitudes in the case of fetal anomaly and in the case of poverty from 2007 to 2016 (n = 20,711; ages = 16+). We measured correlations between abortion attitudes and these important predictors religiosity, attitudes about premarital sex, attitudes about preferential hiring and promotion of women, and attitudes toward family gender roles. Abortion acceptability for poverty increased over time (b = 0.05, p less then  .001), but not for fetal anomaly (b = -0.008, p = .284). Highly religious South Africans reported lower abortion acceptability in both cases (Odds Ratio (OR)anomaly = 0.85, p = .015; ORpoverty = 0.84, p = .02). Premarital sex acceptability strongly and positively predicted abortion acceptability (ORanomaly = 2.63, p less then  .001; ORpoverty = 2.46, p less then  .001). Attitudes about preferential hiring and promotion of women were not associated with abortion attitudes, but favorable attitudes about working mothers were positively associated with abortion acceptability for fetal anomaly ((ORanomaly = 1.09, p = .01; ORpoverty = 1.02, p = .641)). Results suggest negative abortion attitudes remain common in South Africa and are closely tied to religiosity, traditional ideologies about sexuality, and gender role expectations about motherhood.Pre-exposure prophylaxis (PrEP) has been hailed as a revolutionary intervention for HIV prevention. read more PrEP's controversial status in the UK has generated significant media coverage. It is important to understand what role the media plays in framing PrEP policy issues. We undertook a qualitative analysis of UK newsprint articles between 2012 and 2016 to examine how PrEP was framed as a public health intervention up until a controversial policy decision not to provide PrEP in England. We identified how scientific evidence was deployed to shape two narratives ir/responsible citizens focused on imagined PrEP users and their capacity to use PrEP effectively; and the public health imperative, which described the need for PrEP. Our analysis demonstrates the particular ways in which scientific evidence contributed to the certainty of PrEP as an effective intervention within UK newsprint. Scientific evidence also played a key role in framing PrEP as an intervention specifically for cis-gendered gay and bisexual men, playing into wider debates about who is a deserving patient and the appropriate use of public resources. Practitioners in the UK and elsewhere should be aware of these constructions of the PrEP user to ensure equitable access to PrEP beyond gay and bisexual men.Objective To compare suicide rates of people in prison and the general population in the Nordic countries.Methods Data on deaths by suicide and person-years for people in prison and the general population were obtained for the Nordic countries during 2000-2016. Age-standardized rate ratios were calculated.Results The suicide rate in the Nordic countries overall was 110.1 (95% CI = 98.1, 122.2) per 100,000 person-years for people in prison. A significant decline was noted for the suicide rate of people in prison between 2000 and 2016 (p  less then  0.0001). The age-standardized mortality ratio was 7.4 (95% CI = 5.9-8.2) for males and 17.8 (95% CI = 7.3-33.2) for females in Denmark, Iceland, and Norway.Conclusion Despite a decreasing trend over time, excess suicide mortality was noted for people in prison.An essential component of any physical preparation programme is the selection of training exercises to facilitate desired performance outcomes, with practitioners balancing the principles of sports training to inform exercise selection. This study aimed to advance biomechanical understanding of the principles of overload and specificity within exercise selection, utilising novel joint kinetic and intra-limb joint coordination analyses. Three-dimensional kinematic and kinetic data were obtained from six male sprinters (100 m PB, 10.64-11.00) performing block starts (competitive motor task) and seven training exercises that encompassed traditionally viewed general and more specific exercises. Results highlighted the challenging nature of exercise selection, with all exercises demonstrating capacity to overload relevant joint kinetic features of the block start. In addition, all exercises were able to promote the emergence of proximal and in-phase extension joint coordination patterns linked with block start execution, although traditionally viewed non-specific exercises elicited greater overall coordination similarity. The current research helps advance biomechanical understanding of overload and specificity within exercise selection, by demonstrating how exercise selection should not solely be based on perceived replication of a competitive motor task. Instead, practitioners must consider how the musculoskeletal determinants of performance are overloaded, in addition to promoting task specific coordination patterns.
