Research ArticleOpen accessEvery word in the titleEffect of Storing Temperature on Hepatotoxicity and Nephrotoxicity of Ifosfamide in Female RatFalah Mohammed AzizProblem statement: Ifosfamide (IFO) is a cytotoxic alkylating drug used for the treatment of a variety of cancers, although it has been found to induce certain hematological, hepatotoxic and nephrotoxic side effects. This drug is widely used in developing country, especially Iraq, but without caring too much to the storing temperature due to low drug maintaining facilities. The present work … …OnLine Journal of Biological Sciences, Vol. 12, Issue 1 · 19 Mar 2012 · 7,887 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDesign of Synthetic Optimizing Neuro Fuzzy Temperature Controller for Dual Screw Profile Plastic Extruder Using LabviewRavi Samikannu, Balakrishnan Anantharaman PoonamallieProblem statement: The temperature control in plastic extrusion machine is an important factor to produce high quality plastic products. The first order temperature control system in plastic extrusion comprises of coupling effects, long delay time and large time constants. Controlling temperature is very difficult as the process is multistage process and the system coupled with each other. In order to … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 7,120 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSynthesis of Zeolite A from By-Product of Aluminum Etching Process: Effects of Reaction Temperature and Reaction Time on Pore VolumeKanokorn Hussar, Sombat Teekasap, Nisakorn SomsukProblem statement: Increasing of the carbon dioxide (CO2) concentration in the atmosphere creates a global warming. Zeolite is used as CO2 absorbent. Approach: By-products from aluminum etching process, which carry a large amount of Al2O3 content, are useable as raw materials for synthesis zeolites type A using hydrogel process. A pore volume of zeolites is the key to achieve high … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 7,840 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTime Series Analysis of Rainfall and Temperature Interactions in Coastal CatchmentsGurudeo Anand Tularam, Mahbub IlaheeProblem statement: As a result of climate change more work is now being done on climate indices such as SOI, rainfall, temperature and so on. The research concerning rainfall and temperature variations in coastal tropical and subtropical catchments as noted by the dated references in this study shows a lack of attention. The authors examined long term data from coastal … …Journal of Mathematics and Statistics, Vol. 6, Issue 3 · 30 Sep 2010 · 15,828 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Temperature and Time to the Antioxidant Activity in Plecranthus amboinicus Lour.Mohd S. Azman Abdul Rahim, Jailani Salihon, Mashitah Mohd Yusoff et al.Problem statement: Processing of food involving heat will contribute to loss of nutritional content, thus it is important to measure and control temperature and time to reduce the loss. Approach: Examine the effects of variations in boiling temperature and boiling time on the antioxidant activity of the boiling extract of Plecranthus amboinicus Lour. Fresh plants were boiled at 45, 60, … …American Journal of Applied Sciences, Vol. 7, Issue 9 · 30 Sep 2010 · 9,254 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Temperature and Storage Time on Shelf Life of Mycoherbicidal Products of Colletotrichum dematium FGCC#20Jaya Singh, A.K. PandeyProblem statement: The storage environment can have a drastic impact on the stabilization of microbial biopesticides. As a general rule, storing microbial preparation at lower temperature increase long term survivelity. Approach: Optimization of shelf life is critically important for biocontrol products containing living microorganisms. Conidia of Colletotrichum dematium, (FGCC#20) a fungal pathogen of the weed, Parthenium hysterophorus were produced in … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 7,903 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Coupled Mathematical Model for a Temperature Dependant Blood Perfusion in Heterogeneous Biological Tissues during Microwave HeatingE. A. Adebile, B. N. Akintewe, K. M. OwolabiProblem statement: The temperature variation in heterogeneous three layered biological tissues was investigated. Approach: The blood perfusion was considered to be temperature dependent. The heating modalities were taking to go on simultaneously in each of the regions on the one hand and also sequentially in another arrangement. The asymptotic series solution was modified for the three layers and the matching … …American Journal of Applied Sciences, Vol. 7, Issue 5 · 31 May 2010 · 6,580 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSoret and Dufour Effects on Natural Convection Flow Past a Vertical Surface in a Porous Medium with Variable Surface TemperatureHassan A.M. El-ArabawyProblem statement: In this research the researchers studied and made an analysis to the heat and mass transfer characteristics of natural convection about a vertical surface embedded in a saturated porous medium with surface temperature distribution proportional to xλ by taking into account the diffusion-thermo (Dufour) and thermal-diffusion (Soret) effects. Approach: The governing partial differential equations were transformed into a … …Journal of Mathematics and Statistics, Vol. 5, Issue 3 · 30 Sep 2009 · 7,489 accessesView PDFCite
