Pudasainee, Monir Khan, RajenderKumar Gupta","doi":"10.29173/aar50","DOIUrl":"https://doi.org/10.29173/aar50","url":null,"abstract":"Biochar is a kind of charcoal that’s produced from biomass using pyrolysis technology. As climate change continues to be a growing concern, biochar has been sought for its environmental applications. It is both cost effective and environmentally sound in terms of being a soil additive and renewable fuel. When used as a soil amendment, biochar has been shown to improve water holding capacity and absorb more nutrients. Biochar also sequesters carbon dioxide when applied to soil, and can also be used as a replacement for activated carbon that is prepared from coal. The objectives of this research was to produce biochar from biomass and study biochar’s properties. A thermogravimetric analysis (TGA) was used to measure the weight loss behavior of the wood sample (biomass) as the temperature increased. The biomass was heated to 500 °C in a nitrogen atmosphere and then cooled in nitrogen to prevent combustion of biochar. The overall yield of biochar was 15%. Elemental analysis of biomass shows the composition of the sample to be mostly carbon and oxygen with fewer amounts of hydrogen and nitrogen. Surface area of the prepared biochar was 305 m2/g, which is approximately 100 times the surface area of raw biomass. Biochar’s higher porosity will allow for greater absorption of nutrients when applied to soil.","PeriodicalId":239812,"journal":{"name":"Alberta Academic Review","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115004873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The effect of maternal nutritional restriction on fetal development and performance of offspring in beef cattle","authors":"Molly Rainforth","doi":"10.29173/AAR12","DOIUrl":"https://doi.org/10.29173/AAR12","url":null,"abstract":"Health, growth efficiency and carcass quality are major considerations in beef production. The foundation for this is thought to be linked to fetal development. Maternal nutrition during pregnancy is one factor that can influence fetal development and offspring growth. However, its specific effects on postnatal growth of castrated calves (steers) raised for meat are not well understood. This review considers the nutritional requirements of pregnant cows and summarizes the effect of maternal nutritional restriction throughout gestation on calf growth. It also evaluates the different developmental stage at which nutritional restriction will have the greatest impact. It is found that even though early gestation is a critical period for the formation of the placenta and the initial organ development, the fetus has the ability to compensate for developmental restrictions resulting from maternal malnutrition during this period. Meanwhile, during mid-to late gestation maternal nutritional restriction has the greatest impact on offspring performance. Maternal malnutrition during this key period can reduce birth weight, which is strongly correlated to the lifetime performance of steers in terms of health and growth efficiency. Proper nutritional management of cows is essential throughout gestation, but additional attention should be given to the mid-to-late gestational period to ensure calves are born at optimal birth weight. Further, it is suggested that maternal nutrition does not appear to have a consistent effect on carcass quality, instead, external factors near the time of slaughter may be the major determinants.","PeriodicalId":239812,"journal":{"name":"Alberta Academic Review","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133398746","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ofosu, L. D. Saunders, G. Jhangri, A. Alibhai","doi":"10.29173/AAR11","DOIUrl":"https://doi.org/10.29173/AAR11","url":null,"abstract":"The impact of the widespread availability of antiretroviral therapy (ART) on the human immunodeficiency virus and acquired immune deficiency syndrome (HIV/AIDS) related attitudes, behaviours and practices of the general population in Sub-Saharan Africa is understudied. We assessed the impact of ART availability on the fear of HIV/ AIDS (measured at both community and personal levels) and HIV prevention practices in Rwimi, Uganda using a cross-sectional survey. The fear of HIV/AIDS was described as a perceived threat to either self and/or community regarding the risk of contracting the disease, whereby the higher the perception of the threat, the greater the fear. We assessed associations between the outcomes of the dependent variables on both the community and personal fear of HIV/AIDS, and the independent variables of HIV/AIDS-related knowledge and demographics. Qualitative data was also generated from focus group discussions (FGD) on the context of the fear of HIV/AIDS and HIV pre- vention practices. The majority of participants (89.4%; males - 86.8%; females - 90.8%) felt that ART availability has reduced the fear of HIV/AIDS in the community. In contrast, fewer participants (22.4%; males - 24.4%; females – 21.2%) mentioned that their personal fear of HIV/AIDS has been reduced with the availability of ART. From the qualitative study, factors identified as influencing the fear of HIV/AIDS included stigma, fear of infection, and the inconvenience of being on ART. Although fear of HIV/AIDS persists, the fear is reduced because of the availability of life-prolonging ART. HIV prevention practices are influenced by socio-cultural norms (gender roles, relationship dynamics, power and trust), which, we argue, should be considered when de-signing sustainable HIV/AIDS prevention programs.","PeriodicalId":239812,"journal":{"name":"Alberta Academic Review","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126409851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mudde","doi":"10.29173/AAR10","DOIUrl":"https://doi.org/10.29173/AAR10","url":null,"abstract":"This review problematizes the health and socio-economic disparity between Indigenous and non-Indigenous communities, which I argue is due to the role of the Canadian government. Specifically, I analyse the continuous process of Indigenous administrative subjugation under Canadian rule to uncover the intrinsic racial predilections of Canadian government policy toward First Nations peoples in Canada’s Prairie West provinces through the application of diagnostic frame analysis as a multidisciplinary research method to analyse how people understand situations and activities. My research results reveal the racialized marginalization of First Nation peoples through the administrative regimes in Canada as a continuous contemporary process established in the late nineteenth and twentieth century. In exposing the structural discrimination of First Nations peoples, my research introduces the reader to the concept of political master narratives, or ‘imaginaries’. These imaginaries foster the health and socio-economic disparities between Indigenous and non-Indigenous groups in Canadian society. The critical analysis of these historically structural government instituted imaginaries and the indirect, exponentially higher chances of tuberculosis and related diseases and deaths among Indigenous peoples’ challenge conclusions of the Truth and Reconciliation Commission (TRC) on cultural genocide. This study proposes structural genocide as a more accurate and inclusive term for the continuous institutional marginalization of not only Indigenous peoples as seen in this case study of the Department of Indian Affairs (DIA) but for all Indigenous peoples in Canada.","PeriodicalId":239812,"journal":{"name":"Alberta Academic Review","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114493739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
