Research ArticleOpen accessEvery word in the titleAnalysis of Some Pesticide Residues in Cauliflower by High Performance Liquid ChromatographySheheli Islam, Nazneen Afrin, Mohammad Shawkat Hossain et al.Problem statement: Increased use of chemicals on vegetables started gaining momentum and continued its up-trend in Bangladesh. Wide spread use of pesticides in agriculture concern of residue accumulation, which may remain in food and agricultural environment causing concern of human health and risking ecological balance. Attempt made to ensure that their applications were correct and safe and result in no … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,859 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNematic and Smectic Mesophase from Calamitic Bisazobenzene Liquid Crystal: Synthesis and Characterization of 1- Methoxyhexyloxy-4'-(4-Phenylazo) Azobenzene Hybrid MoleculeSidik Silong, Abdulsalam Abubakar Salisu, Muhamad Zaki Ab Rahman et al.A new hybrid calamitic liquid crystal material with rod-shape bisazobenzene moieties as a core has been synthesized and characterized by spectroscopic methods. The mesomorphic properties were investigated by differential scanning colorimetry, polarizing optical microscopy and X-Ray diffraction. The rod-shaped molecule 1- methoxyhexyloxy-4`-(4-phenylazo)azobenzene was prepared by diazotization of 4-phenylazoaniline, coupling with phenol and subsequent etherification of 1-Bromohexyloxy-4`-(4-phenylazo)azobenzene in methanol. The presence … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,980 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleReduction of Ammonia Loss by Mixing Urea with Liquid Humic and Fulvic Acids Isolated from Tropical Peat SoilSusilawati Kasim, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid et al.Problem statement: Fertilizer N use efficiency is reduced by ammonia volatilization. Under low soil CEC and high pH, N from soil solution is released to the atmosphere. Ammonia loss due to low worldwide N use efficiency (33%) has been implicated in global warming. Thus, the objectives of this laboratory study were to evaluate the effectiveness of liquid humic and fulvic … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 9,513 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSeparation of Guanine and Hypoxanthine with Some Ionic Liquids in RP-HPLCJ. Zheng, K. H. RowIn this paper, guanine and hypoxanthine were separated with four different ionic liquids as additives for the mobile phase using reversed phase high performance liquid chromatography (RP-HPLC). The ionic liquids, 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIm][BF4]), 1-ethyl-3-methylimidazolium tetrafluoroborate ([EMIm][BF4]), 1-ethyl-3-methylimidazolium methylsulfate ([EMIm][MS]) and 1-octyl-3-methylimidazolium methylsulfate ([OMIm][MS]) were used. Guanine and hypoxanthine couldn’t be separated with many different kinds of unadjusted mobile phase, such … …American Journal of Applied Sciences, Vol. 3, Issue 12 · 31 Dec 2006 · 6,892 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Application of Ionic Liquids in Catholic Coupling of AcetophenonePo-Chung ChengProblem statement: The cathodic coupling of acetophnone was carried out in aqueous solutions containing sodium sulfate and 1-Octyl-3-Methylimidazolium Chloride ([OMIM]Cl) as supporting electrolytes. [OMIM]Cl is an ionic liquid, also serving as a co-solvent to prevent the deposition of products during electrolysis. The products are extracted with ether after electrolyses. Approach: It is shown in this study that the recycling of … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 7,039 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleRETRACTED: Toxicity Assessment of Phosphonium Based Ionic Liquids Towards Female Guppy FishMohanad El-Harbawi, Yasmin Syazwani Bt. Yusri, M. Ismail HossainIn this study, two phosphonium based ionic liquids (butyl triphenyl phosphonium chloride and hexyl triphenyl phosphonium bromide) have been synthesized using quarternisation process. The toxicities of these Ionic Liquids (ILs) are unknown and may be harmful to humans and the environment. Therefore, the toxicity assessment of these ILs was carried out according to the Organization for Economic Cooperation and Development … …American Journal of Environmental Sciences, Vol. 9, Issue 6 · 20 Jan 2014 · 6,851 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSome Effects of Alternative Foreign Currency Translation Methodologies on two Short-Term Liquidity RatiosPaul E. HoltThis study focused on two short-term liquidity ratios, the current ratio and inventory turnover and attempted to identify, in terms of empirical properties, if and in what ways foreign currency translation methodologies generate different results. Fifty companies’ accounts were translated from U.S. dollars to U.K. pounds. Post-translation Spearman rank correlation coefficients were extremely high for all methodology pairs, but t … …American Journal of Economics and Business Administration, Vol. 3, Issue 4 · 8 Mar 2012 · 7,484 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInfluence of Two-Phase Liquid-Gas Flow on Permeate Flux through Ceramic MembranesTomáš Bakalár, Milan Búgel, Gabriel Müller, Štefan SaboThe impact of two-phase flow onto the flux of the permeate in microfiltration of two sorbents-Bentonite and Lewatit S1468-with and without adsorbed zinc, was examined. Two different types of membrane, single-and multi-channel, based on α-Al2O3, were used. In single-channel membrane application of aeration increased the permeate flux by 13 and 29% without adsorbed zinc and by 22 and 25% with … …American Journal of Applied Sciences, Vol. 12, Issue 12 · 10 Dec 2015 · 6,765 accessesView PDFCite
