Research ArticleOpen accessIn the abstractCocaine Exposure Results in Formation of Dendritic Varicosity in Rat Primary Hippocampal NeuronsHonghong Yao, Crystal Bethel-Brown, Anil Kumar, Shilpa BuchProblem statement: It has been well documented that drugs of abuse such as cocaine can cause enhanced progression of HIV-Associated Neuropathological Disorders (HAND), the underlying mechanisms mediating these effects remain poorly understood. Approach: In present study, we explored the impact of cocaine exposure (I and 10 μM) on the dendritic beading in rat primary hippocampal neurons. Using the approach of … …American Journal of Infectious Diseases, Vol. 5, Issue 1 · 31 Mar 2009 · 7,889 accessesView PDFCite
Research ArticleOpen accessIn the abstractAir-Cooling Used For Metal CuttingBrian Boswell, Behrad Katirachi, Tilak T ChandratillekeAir-cooling and dry machining are both being trialled as possible solutions to the metal cutting industry’s long running problems of extending tool life, reducing tool failure and minimising the heat generation at the tool tip. To date, large amounts of expensive coolant which cause both environmental damage and health hazards have had to be used. The introduction of dry machining … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 8,214 accessesView PDFCite

Research ArticleOpen accessIn the abstractBiotic and Abiotic Factors of Sperm nDNA Fragmentation in Farm AnimalsBaylar Iolchiev, Natalya Volkova, Pavel Klenovitskiy et al.Infertility and subfertility are among the global challenges of our time. Fertility in livestock farming is not only biologically important, it is also economically important. The aim of this study was to study the effect of these factors on sperm chromatin nucleus and to assess the impact of the fragmentation index degree on bull reproductive performance. The influence of abiotic … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 1 · 11 Mar 2021 · 6,714 accessesView PDFCite
Research ArticleOpen accessIn the abstractMeasuring the Resiliency of the Manhattan Points of Entry in the Face of Severe DisruptionMayada Omer, Ali Mostashari, Roshanak NilchianiProblem statement: Resilient infrastructure systems are able to continue to provide the expected service levels following disruptive events. Implementing resiliency in infrastructure systems requires knowledge of the current resiliency of the system and a methodology by which different resiliency strategies can be evaluated. In the transportation infrastructure in particular, disruptions cause delays, which will in turn incur substantial economic losses … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 15 Mar 2011 · 9,671 accessesView PDFCite
