Safila Naveed, Fatima Qamar
Open Access Library Journal (OALib Journal) , 2014, DOI: 10.4236/oalib.1100614
Abstract: Esomeprazole is the S-isomer of Omeprazole and it is a proton pump inhibitor (PPI). Esomeprazole is used in acid-related disorders and it is available as several brands in the market which makes it difficult for doctors to select the effective, safe and economic one for patients. Therefore we have decided to establish pharmaceutical equivalence among the different brands of esomeprazole available in Karachi, Pakistan. In our present study different brands of esomeprazole are evaluated for weight variation, hardness and dissolution. Disintegration Test shows results for NEX 01, ESS 02, EZI 03 and they disintegrate in 1.35, 1.15 and 2.15 minutes respectively. Dissolution test demonstrate the result as NEX 01, ESS 02, EZI 03 is 100.00% for NEX, 117.87% for ESS and 80.66%. The results showed that all parameters weight-variation, hardness, dissolution of different brands of esomeprazole are in accordance with the USP limits.
Simple UV Spectrophotometric Assay of Metronidazole  [PDF]
Safila Naveed, Fatima Qamar
Open Access Library Journal (OALib Journal) , 2014, DOI: 10.4236/oalib.1100615
Abstract: Metronidazole is a derivative of benzimidazole. It is being used widely for the treatment of amoebiasis. An efficient, simple and least time consuming spectrophotometric method for the assay of metronidazole has been developed. Comparison of assay of three different brands of metroni-da- zole has also been available in public medical stores of Karachi, Pakistan. The assay is based on the ultraviolet UV absorbance maxima at about 340 nm wavelength of metronidazole using water as solvent. A sample of drug was dissolved in water to produce a solution containing metronidazole. Similarly, a sample of ground tablets of different brands were dissolved in water and various dilutions were made. The absorbance of sample preparation was measured at 340 nm against the solvent blank and the assay was determined by comparing with the absorbance of available brand. The method can be applied for the routine QC quantitation of metronidazole in tablet formulation actively.
HFBUIT: Design Aid Tools For A Human Factor Based User Interface Design
Prof.(Dr.)S.Qamar Abbas,Shahnaz Fatima
Indian Journal of Computer Science and Engineering , 2010,
Abstract: Exploring user interface design and development problems is the core of current HCI research. Although there have been considerableadvancements in computer technology, human factors considerations are still lacking. This results in the user frequently becoming confused or frustrated when trying to interact with the software. Designers should utilize the knowledge about the user to configure the interface for different users, i.e. each user may have different skills, level of experience, or cognitive and physical abilities. This paper offers a five phase framework of a tool that might help designers to design a Human Factors based user interface.
Clinical Implications of Tumor Necrosis Factor-Alpha, Interleukin-6 and Resistin in Coronary Artery Disease  [PDF]

World Journal of Cardiovascular Diseases (WJCD) , 2014, DOI: 10.4236/wjcd.2014.49052

Tumor necrosis factor alpha (TNF-alpha) and interleukin-6 (IL-6) are involved in the progression of coronary artery disease (CAD). The cytokines’ levels are associated with the severity of CAD. We have recently reported on the association of resistin, a relatively novel cytokine with the pathogenesis of cardiovascular disease (CVD). Although the inflammatory cytokines’ impact on atherosclerosis is widely accepted, yet some controversy exists regarding the involvement of these factors in atherogenesis. The current review highlights the potential association of TNF-alpha, IL-6 and resistin SNPs (single nucleotide polymorphisms) with CAD. Molecular genetics data along with the intracellular signaling cascade mechanisms may have important clinical implications in the treatment of CAD.

Abstract: Biotin is also called vitamin B7, vitamin B8 or vitamin H. Biotin is a water soluble compound and is colorless in appearance. Overall eight different types of biotin exist but only Biotin-D occurs naturally with its complete vitamin activity. It is mainly synthesized by mold, algae, bacteria, yeast and some plant species. There are different methods used to find the vitamins in nutrients and samples. This article is composed of the comprehensive review of the competitive techniques and various methods for the assay of biotin. High-pressure liquid chromatographic (HPLC), microbiological analysis and HPLC producer are adopted for the determination of biotin. An optimal analytical condition of biotin determination was performed by the HPCL method. The statistical parameters of the HPLC methods were compared and reviewed with other determination.

Abdul Rehman, Rafi Qamar, Jamshaid Qamar
Journal of Agricultural Chemistry and Environment (JACEN) , 2014, DOI: 10.4236/jacen.2014.33B004

Sugarcane has pronounced importance to provide sugar for more than half of the global population. World population is enhancing day-by-day and production land is in the worst situation. The cultivated land is diminishing rapidly due to urbanization, road construction, and land deterioration. This crisis demands alternate research to raise crop productivity and maximize the economic returns per unit land for feeding the gigantic population. Sugarcane is a long duration crop and gave late net economic return. Intercropping in sugarcane received much attention and need to properly manage for getting higher net return from same unit area. It is becoming popular among farming community due to resourcefully utilization of land. Intercropping has the potential to inspire the farmers to get maximum economic return per acre per annum. For intercropping, wheat, gram, soybean, and potato were used as an intercrop in September-sown sugarcane. Triple row strip planting geometry of sugarcane with four intercropped (SC + Wheat, SC + Gram, SC + Soybean, and SC + Potato) and check with sole SC was used. Sugarcane was planted during September 2011- 12 and 2012-13 at research area University College of Agriculture, University of Sargodha, Pakistan. Randomized complete block design with three replications were used. Results showed that number of millable cane, cane diameter; unstripped and stripped cane yield and crop growth rate was significantly higher in sole sugarcane when compared with different intercrop in 2011-12 while trend was same in 2012-13. Cane diameter and un-stripped cane yield were statistically at par of intercrops SC + Soybean and SC + Potato while stripped cane yield of Sole SC and SC + Potato was statistically at par in 2012-13. In both the year of study, intercrops gave higher land equivalent ratio and net return over sole sugarcane planted while sole sugarcane gave maximum benefit cost ratio compared with other intercrops.

Abstract: Five types of haemocytes have been identified in the haemolymph of 5th instar nymphs and adults of the redcotton bug, Dysdercus cingulatus. Changes in the Differential Haemocyte Counts (DHCs) have been assessed inrelation to application of graded concentrations of Acephate. The haemogram profile was determined 6 hr, 1 day,3 days, 5 days post-treatment as well as post-moulting i.e. in the adult males and females. Different types ofhaemocytes registered a dose-dependent response by either exhibiting increase or decrease in their relativeproportions. The adipohaemocytes were the most sensitive cells to the insecticidal stress whereas theoenocytoids showed least damage to their cellular integrity. However, there was a consistent increase in theproportion of damage/unidentifiable blood cells in accordance with increase in concentration of acephate applied.Furthermore, the treated insects apparently responded by releasing more prohaemocytes, the so called “stemcells”, into the circulation as evident by increase in the percentage of these cells in treated blood smearscompared to the parallel control.
Towards an Indigenous Perspective on HRM: A Study of Textile Industry of Pakistan
Qamar Ali
International Journal of Management and Organizational Studies , 2012,
Abstract: The purpose of this study was to identify external and internal forces shaping HRM practices in textile industry of Pakistan. The study aimed at describing the context-specific HRM practices in textile industry. Interviews were used as a source of primary data collection. Taking Faisalabad city as a case, top HRM officials from ten respondent organizations in textile industry were interviewed. An interpretive approach to research design was adopted using ‘human as an instrument’ for data analysis. Findings suggest that due to extensive competition in last few years HR planning has received serious attention in textile industry. Countries like China, India, and Bangladesh are posing huge threats to the industry. The industry is at best dominated by family owned businesses and now the young generation, after education from abroad, is taking charge of their parents. Assumptions about workers are getting transformed. Fresh leaders are thinking different from their predecessors. However, there is a state of inertia in textile industry where young leaders have an uphill task ahead to remove the obstacles in the course of change.
A new approach for reduction of methylene green withascorbic acid by de-oxygenation through carbondioxide  [PDF]
Rafia Azmat, Noshab Qamar, Raheela Naz
Natural Science (NS) , 2011, DOI: 10.4236/ns.2011.37079
Abstract: Reduction kinetics of the methylene green (MG) with ascorbic acid (AA) in acidic medium at λmax 660 nm was monitored through visible spectrophotomtry in absence and presence of sodium carbonate. CO2 release through reaction of sodium carbonate and oxalic acid, created deoxygenated atmosphere for reduction of dye which greatly boosted the reaction rate. Initially slow reaction in presence of atmospheric oxygen proceeded rapidly when sodium carbonate was added. The reaction followed fractional order kinetics with AA and zero order kinetics with MG. The rate of reaction shows no linear dependence on [H+] concentration as an acidic medium. The rate of reaction is directly related with the elevated concentration of salt, which suggests that the two same charged species are involved in the rate determining step. Secondary reactions at elevated temperature showed complex kinetics.
