Research ArticleOpen accessEvery word in the titleVariability of Chloroplast DNA of Extranuclear Sunflower MutantsMarkin Nicolay, Aieksandr Usatov, Maria Logacheva et al.A comparative analysis of full-genome sequences of chloroplast DNA (cpDNA) of the original inbred line 3629 and three extranuclear mutants, which were obtained by the method of mutagenesis induced with N-nitroso-N-methylurea (NMU) and characterized by different level of chlorophyll insufficiency (en:chlorina-7-yellow-green leaves; chlorophyll content (a + b)-67.8% with respect to the line 3629, variegated-10-leaves with white zones; chlorophyll content (a … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 1 · 26 Mar 2016 · 7,269 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleVARIABILITY IN THE LIGNINOLYTIC ENZYMES ACTIVITY BY LENTINULA EDODES IN SUBMERGED CULTURE WITH LIGNIN AND GLUCOSECitlalli Harris-Valle, Elisa Valenzuela-Soto, Alfonso Sánchez et al.The white-rot basidiomycete Lentinula edodes is the second most edible mushroom cultivated on the world. This fungus decomposes cell-wall associated macromolecules, is a natural degrader of lignin polymers. The differences in enzyme activities between strains of L. edodes provided useful information about the participation of enzymes in different development stages of the fungus. The effect of lignin on the fungal … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 28 Apr 2014 · 7,845 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTemporal Variability on Lowland River Sediment Properties and YieldMohd Khairul Amri Kamarudin, Mohd Ekhwan Toriman, A.S. Sharifah Mastura et al.Problem statement: A sediment analysis study was conducted at the Chini River on 16 and 31 August 2008. This study was conducted to review the formation of suspended sediment load in the Lake Chini catchment area, which flows into the Pahang River via the Chini River. Approach: Three sampling stations were chosen, the first one at upstream Chini River (S1), … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 7,188 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleVariability in Antihypertensive Drug Therapy and Compliance: Results from a Random Survey in the United Arab EmiratesSyed Azhar Syed Sulaiman, Muaed Jamal Alomar, Claire Caroline StrauchProblem statement: Hypertension is one of the most common diseases known as the ‘silent killer’ because it shows no clinical signs and symptoms. The high prevalence of hypertension in the United Arab Emirates stresses the importance to initiate a nation-wide effort to prevent and control high blood pressure in the population, especially since the prevalence rates are indicative of one … …American Journal of Pharmacology and Toxicology, Vol. 4, Issue 3 · 30 Sep 2009 · 7,230 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDerivation of the Limits for Control Chart Using the Median Absolute Deviation for Monitoring Non-Normal ProcessK. S. Adekeye, P. I. AzubuikeProblem statement: The Shewhart and S control charts, in the literature, were combined to evaluate the stability of a process. These charts were based on the fundamental assumption of normality of the quality characteristics under investigation. Approach: In practice, the normality assumption was often violated by real life data, therefore, use of the Shewhart and S control charts on real … …Journal of Mathematics and Statistics, Vol. 8, Issue 1 · 24 Dec 2011 · 8,435 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMorphological Characterization and Variation in the Total Content of Reducing Sugars in Wild Populations of Agave angustifolia HawMartin Esqueda, Aldo Gutierrez, Guadalupe Palomino et al.Problem statement: Bacanora, a spirit, is distilled from wild populations of Agave angustifolia Haw. Loss of biodiversity must be taken into account when proposing sustainable management actions for this resource. In this study we identified the morphological variants of this species, as well as the weight and Total Content of Reducing Sugars (TRS) in the stem of the agave. Approach: … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 4 · 21 Oct 2011 · 8,553 accessesView PDFCite

Research ArticleOpen accessIn the keywordsUsing Soil Plant Analysis Development Chlorophyll Meter for Two Growth Stages to Assess Grain Yield of Malaysian Rice (Oryza sativa)Asa Gholizadeh, Mohd Amin Mohd Soom, Anuar Abd. Rahim, Aimrun WayayokProblem Statement: Proper yield management in rice influences grain quality and quantity. Nitrogen site-specific management is also effective on final product of crops because excessive nitrogen application at any growth stage can reduce yield and increase disease incidence. In contrast, suboptimal nitrogen levels at discrete growth stages may substantially reduce plant productivity. The nitrogen status at specific growth stages may … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 6 Jun 2011 · 11,820 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSugar Beet Performance Affected by Uniformity of N FertigationH. Nouri, M. S.M. Amin, S. J. Razavi et al.In common with the majority of crop species, in sugar beet nutrition nitrogen is an important element due to its role in sucrose utilization and plant growth. Application of precision agriculture, in order to apply the right amount of input at the right time in the right area, is appropriate to decrease chemical use and increase plant growth. Problem statement: … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 7,931 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEvaluation of Leaf Total Nitrogen Content for Nitrogen Management in a Malaysian Paddy Field by Using Soil Plant Analysis Development Chlorophyll MeterA. Gholizadeh, M. S. M. Amin, A. R. Anuar, W. AimrunProblem statement: Laboratory plant testing is usually time-consuming and high-costing. Hence, plant nutrient variability must be measured rapidly and the information made known to the farmers before the new season starts. Site-specific crop management, well-established in some developed countries, is now being considered in other places such as Malaysia. Approach: The application of site-specific management principles and techniques to diverse … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 9,238 accessesView PDFCite
