Research ArticleOpen accessIn the keywordsPhysico-Chemical Characteristics of Date Seed Oil Grown in SudanRehab Salih Mahmoud Abdalla, Alsheikh AlGilani Albasheer, Abdel Rahim Mohamed ELHussein, ELrasheed Ahmed GadkariemProblem statement: Studies were conducted on the physical-chemical properties of Sudanese date seed oil extracted from two date palm cultivars (Phoenix dactylifera L.) ALBarakawi and Alqundeila. The extracted oil from ALBarakawi seeds weighed 6.833% w/w oil, Alqundeila oil extracted weighed 5.064% w/w. Approach: The physical properties of ALBarakawi oil were: viscosity: 17cp, refractive Index: 1.444, density: 0.9116 g cm-3 color: … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 5 May 2012 · 9,500 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAnalysis of Diffusion Coefficient using Reversed-Flow Gas Chromatography-A ReviewKhalisanni Khalid, Rashid Atta Khan, Sharifuddin Mohd. ZainProblem statement: Since the earliest publication on the technique, Reversed-Flow Gas Chromatography (RF-GC) has been used to determine physicochemical properties by measuring the value of one in the presence of another. The method is precise, accurate and simple compared to other conventional techniques. Approach: The experimental setup consists of a small modification of a commercial gas chromatograph, so that it … …American Journal of Applied Sciences, Vol. 8, Issue 5 · 17 May 2011 · 7,223 accessesView PDFCite
Research ArticleOpen accessIn the keywordsHeroin-Induces Differential Protein Expression by Normal Human Astrocytes (NHA)Jessica L. Reynolds, Supriya D. Mahajan, Donald Sykes, Madhavan P.N. NairHeroin use is postulated to act as a cofactor in the neuropathogenesis of human immunodeficiency virus (HIV-1) infection. Astrocytes, integral components of the CNS, are reported to be susceptible to HIV-1 infection. Upon activation, astrocytes release a number of immunoregulatory products or modulate the expression of a number of proteins that foster the immunopathogenesis of HIV-1 infection. However, the role … …American Journal of Infectious Diseases, Vol. 2, Issue 2 · 30 Jun 2006 · 7,261 accessesView PDFCite
