Research ArticleOpen accessIn the abstractFACILE SYNTHESIS OF IN-VIVO INSECTICIDAL AND ANTIMICROBIAL EVALUATION OF BIS HETEROCYCLIC MOIETY FROM PET WASTEAsmaa Mahmoud Fahim, El Sayed Mohamed Yakout, Galal Abd ElMohein NawwarRecycling of Plastic Solid Waste (PSW) using green tool such as solar energy which used for degradation of plastic solid bottles (PET) to afford terepthalic acid which estrified using butanol/H2SO4 to afford dibutyl terephthalate as a starting material which has been chemically modified to yield new bis (1,2,4-triazole-3-thiol) 5, 1,3,4-oxadiazole 6, 8, 15, 1,3-thiazolidine 9, 1 H-pyrazole 10, 11 and … …OnLine Journal of Biological Sciences, Vol. 14, Issue 3 · 21 Aug 2014 · 7,373 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStudy of the Effects Irrigation Water Sanity and pH on Production and Relative Absorption of some Elements Nutrient by the Tomato PlantHossein Afshari, Shahram Ashraf, Abdol Ghaffar Ebadi et al.Problem statement: This study was conducted to examine the effects of irrigation water pH and Salinity on the growth and absorption of P, Na, Ca, K by tomato. Approach:The study includes two Salinity and pH factors and is consisted from 12 treatment and three repetitions. Tomato seeding grown in foam trays were transplanted in the joune 2010 to bags filled … …American Journal of Applied Sciences, Vol. 8, Issue 8 · 18 Jul 2011 · 7,695 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Some Fermentation Parameters on Ethanol Production from Beet Molasses by Saccharomyces cerevisiae CAIM13Awatif Abid Al-JudaibiProblem Statement: Some component of fermentation medium showed to reduce the Saccharomyces cerivisae production of ethanol. Approach: This study was designed to evaluate the role of some fermentation parameters in affecting ethanol productivity from beet molasses BM by Saccharomyces cerevisiae CAIM13. Results: Increase in cell concentration (inoculums size) of the yeast above 3.6×105 cells/100 mL decreased the ethanol yield. The … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 25 Jun 2011 · 8,921 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBuffering Capacity of Fast-Growing Species and Curing Time of UF Resin Modified With Zinc Borate and Monoammonium PhosphateIzran Kamal, Koh Mok Poh, Tan Yu Eng et al.Problem statement: Occupying a suitable hot pressing time for particleboard fabrication seems very tricky for manufacturers of the wood-based panel. Longer or shorter pressing times can affect physical and mechanical properties of the produced particleboards and that is why extra care should be given on this matter. Longer pressing time can cause resin in a particleboard to over-cure whereas shorter … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 7,777 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBasic and Reactive Dyes Sorption Enhancement of Rice Hull through Chemical ModificationSiew-Teng Ong, Pei-Sin Keng, Chnoong-Kheng LeeProblem statement: Many studies have been conducted on the removal of either anionic or cationic dyes. However, as a mixture of dyes does commonly exist together in wastewater, therefore it is of great interest to have a material that can remove both types of dyes. Approach: To prepare an inexpensive and efficient sorbent by chemically modifying rice hull for the … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 7,787 accessesView PDF Cite

Research ArticleOpen accessIn the abstractExperimental Study of Parameters Influencing the Purity of Potassium Sulfate Fertilizer Produced from Jordanian Raw MaterialsMousa GougazehThe general objective of the present investigation was to make a contribution towards improving the purity of the produced potassium sulfate from (KCl, Arab Potash Company-Dead Sea) and (H2SO4, Jordanian Phosphate Company). The process parameters influencing the contamination of the poisoning chlorine within the product were experimentally investigated. The experiments were performed in a small-scale batch reactor equipped with a … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 7,042 accessesView PDF Cite
