Research ArticleOpen accessIn the keywordsTRANSPIRATION INFLUENCES CADMIUM UPTAKE BY BABY LEAF SPINACH (SPINACIA OLERACEA L.)Carlo Chehine, Paul Holford, Oula Ghannoum et al.Cadmium (Cd) is a toxic heavy metal whose concentration in soils is rising. This study investigated the effect of transpiration on Cd uptake by plants using soil conditions akin to those experienced by field crops. Two experiments were performed using baby leaf spinach (Spinacia oleracea L.) grown in soil containing Chloride (Cl) at a typical concentration of 70 mg kg-1. … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 4 · 23 Dec 2014 · 8,065 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPOST-HARVEST CONTROL OF APPLE BLUE MOLD UNDER COLD STORAGE CONDITIONSZiad B. Al-Rawashdeh, Muwaffaq R. KarajehTo control blue mold of apples caused by Penicillium expansum after harvest and during commercial cold storage, microwave exposure was investigated as a physical measure and compared with the use of calcium chloride and the systemic fungicide, carbendazime. Microwave exposure of Golden Delicious and Royal Gala apples at 2450 Mhz for 10, 30 and 45s was effective as 4% CaCl2 … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 2 · 23 Jan 2014 · 7,521 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPlastic Membrane Electrodes of Coated Wire Type for Micro Determination of Quininium Cation in Pharmaceutical TabletsLaila Abdullah Al Shatti, Hayat Mohammed Marafie, Adel Fahmi ShoukryProblem statement: Silver and copper all-solid state wire sensor electrodes of quininium cation with different ion exchangers have been prepared and used in pharmaceutical analysis. A comparative study with a reference method is applied in order to investigate the validity of the proposed method for potentiometric analysis of pharmaceutical compounds containing quinine. Approach: A Nernstian equation was proved for all … …American Journal of Applied Sciences, Vol. 8, Issue 2 · 28 Feb 2011 · 7,690 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOptimizing Coagulation Process for Low to High Turbidity Waters Using Aluminum and Iron SaltsAkbar Baghvand, Ali Daryabeigi Zand, Nasser Mehrdadi, Abdolreza KarbassiProblem statement: Turbid waters, containing colloidal particles, are normally treated by coagulation-flocculation followed by clarification. Ferric chloride and alum, which are the most common types of coagulants in water treatment plants of Iran as well as many other countries, were investigated with the aim of determining their capabilities to reduce turbidity of drinking water. Turbidity was added as kaolin. Optimization … …American Journal of Environmental Sciences, Vol. 6, Issue 5 · 31 Oct 2010 · 21,079 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBehavior of Stabilized Peat Soils in Unconfined Compression TestsWong Leong Sing, Roslan Hashim, Faisal Haji AliProblem statement: Deep stabilized peat columns were known to be economical at forming foundations to support highway embankments constructed on deep peat land. However, failure in the formation of the columns with adequate strength was often attributed to unsuitable type and insufficient dosage of binder added to the soil. Organic matter in peat was known to impede the cementing process … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,452 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffects of Different Concentrations and Applications of Calcium on Storage Life and Physicochemical Characteristics of Papaya (Carica Papaya L.)T.M.M. Mahmud, A. Al Eryani-Raqeeb, S.R. Syed Omar et al.Papaya (Carica Papaya L.) fruits index 2 were treated with 1.5, 2.5 and 3.5% solutions of calcium chloride by dipping and vacuum infiltration (-33 Kpa) or untreated (0%) as control. Effects of these treatments were evaluated on storage life and postharvest quality characteristics of papaya. After 21 days of storage at 13±1°C, the fruits were removed from storage for physicochemical … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 3 · 30 Sep 2008 · 9,652 accessesView PDFCite

Research ArticleOpen accessIn the keywordsOptimum Conditions for Measuring Dehydrogenase Activity of Aspergillus niger using TTCA. E. Ghaly, N. S. MahmoudThe suitability of the triphenyl tetrazolium chloride (TTC) for dehydrogenase activity measurement of the vegetative cells of the fungal species Aspergillus niger was investigated. The triphenyl formazan (TF) yield increased with the increases in TTC concentration, pH, temperature and incubation time within the studied ranges. The effects of individual parameters, as well as the combined effects, on the TF yield … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 4 · 31 Dec 2006 · 9,002 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect of MgCl2 on Germination, Growth and Biomass Allocation of the Radish CV. "Cherry Belle"William Brandenburg, Catherine KleierProblem statement: To determine the effect of MgCl2 on radish (Raphanus sativus), plants were grown in controlled environmental growth chambers and given one of three watering treatments; 0.01, 0.1 and 0 M (control) MgCl2. Approach: At high concentrations (0.1 M), MgCl2 was toxic resulting in very low (44%) germination rates and the subsequent death of all but three undersized plants … …American Journal of Environmental Sciences, Vol. 7, Issue 2 · 26 May 2011 · 8,232 accessesView PDFCite
