Research ArticleOpen accessIn the abstractBRASSINOSTEROIDS IN BREEDING TECHNOLOGIES HEALTHCARE POTATONatalia Nikolaevna Koposova, Olga Veniaminovna Shtyrlina, Irina Pavlovna Uromova et al.The regulator of anti-stress action Epin-Extra (24-epibrassinolide) was tested in laboratory and field (protected ground) conditions. The aim of this research was to study the influence of growth regulators on the growth, development and productivity of improved initial promising varieties of potato: Native (cultivated varieties Udacha) and foreign (cultivated varieties Red Scarlett) selections obtained by the method of apical meristem … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 28 Aug 2014 · 7,322 accessesView PDFCite
Research ArticleOpen accessIn the abstractASCORBIC ACID FOLIIAR SPRAY COUNTERACTING EFFECT OF SALINITY ON GROWTH, NUTRIENTS CONCENTRATIONS, PHOTOSYNTHESIS, ANTIOXIDANT ACTIVITIES AND LIPID PEROXIDATION OF BEAN (PHASEULUS VULGARIS L.) CULTIVARSZeinab A. Salama, El-Zanaty A.A. Abou El-Nour, Mohamed M. El Fouly, Alaa A. GaafarA water culture experiment was carried out in the Department of Fertilization Technology at National Research Centre, Cairo, Egypt, to investigate the effect of Ascorbic Acid (AsA) foliar application and salinity stress (100 ppm and 100 mmoL NaCl) on growth, nutrients concentration and some biochemical parameters of two kidney bean (Phaseulus Vulgaris L.) cultivars. Salinity caused significant reduction in growth … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 16 May 2014 · 7,900 accessesView PDFCite
Research ArticleOpen accessIn the abstractEVALUATION FOR SALT STRESS TOLERANCE IN TWO STRAWBERRY CULTIVARSW. Al-Shorafa, A. Mahadeen, K. Al-AbsiSalt stress conditions have been found to destroy the vital physiological process in plant where slower cell division and cell enlargement or both and limit mineral nutrient uptake with clearly nutritional imbalance. A greenhouse pot experiment was carried out at Agricultural Research Station, Mu’tah University, Jordan to evaluate growth responses and mineral composition of two strawberry cultivars to salt stress … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 14 Apr 2014 · 7,697 accessesView PDFCite
Research ArticleOpen accessIn the abstractAgro-Process Intensification through Synthetic Rhizosphere Media for Nitrogen Fixation and Yield Enhancement in PlantsG. Akay, D. R. BurkeProblem statement: In order to combat global warming and the emerging Food, Energy and Water shortages (FEWs), several approaches have been adopted, including genetic engineering and farming practices. Biomass based energy technology will further stress food and water resources and hence novel holistic approaches to FEWs should be designed. Approach: A novel technique (Agro-Process Intensification, A-PI) which simultaneously addresses FEWs … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 2 · 15 Mar 2012 · 8,599 accessesView PDFCite
Research ArticleOpen accessIn the abstractNutritional Supplements and its Effect on Quality of Life and SleepSara Sarrafi Zadeh, Khyrunnisa BegumProblem statement: Inadequate sleep has been recognized as a risk factor for poor health status. Mental stress, body pains, melatonin deficiency, late night awakening disturbing the body clock are triggers for poor quality of sleep and fatigue. Fatigue due to insomnia is a major cause for poor quality of life. Evidences suggest certain nutrients to exert profound influence on quality … …Current Research in Medicine, Vol. 2, Issue 2 · 1 Dec 2011 · 9,258 accessesView PDFCite
Research ArticleOpen accessIn the abstractBioengineering Assessment on Sloppy GroundMu'azu Mohammed Abdullahi, Nazri Bn Ali, Kamarudin Bn Haj AhmedProblem statement: Soft engineering solution of sloppy surface utilizes mechanical and hydrological effects of vegetation. The hydrological effects driven by transpiration, induces an increase in matric suction and consequently tension also increase along with the decrease of moisture. Therefore once the horizontal stress of the soil exceeds the limit of tensile strain of the soil cracks occurs. Approach: The negative … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 7,242 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of Vegetative Induced Deformation in an Unsaturated SoilNazri Bn Ali, Mu’azu Mohammed AbdullahiProblem statement: Tree root water-uptake increases soil strength by increasing the soil matric suction due to pore pressure dissipation in a soil mass, inducing increases in vertical total stress or water extraction, the effective stress to which the soil strata is subjected to may also increase. This causes volume change which might be detrimental to geotechnical structures and shallow foundation. … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 7,135 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Cycocel and Irrigation Regimes on Some Physiological Parameters of Three Olive CultivarsMaisam Nejadsahebi, Noorollah Moallemi, Ahmad LandiProblem statement: The water deficiency is one of the serious problems, in the arid zones. Cycocel by increasing the stomata resistance and decreasing transpiration can help to water use efficiency. Approach: In this research the impacts of different doses of Cycocel (0, 500 and 1000 mg L-1) and irrigation regimes (33, 66 and 100% of available water; referred to as … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 7,976 accessesView PDFCite
Research ArticleOpen accessIn the abstractRating of Spur Gear Strength Using Photoelasticity and the Finite Element MethodKonstandinos G. Raptis, Theodore N. Costopoulos, Georgios A. Papadopoulos, Αndonios D. TsolakisProblem statement: Toothed gears are some of the most used machine elements for motion and power transmission between rotating shafts. This fact induces the need for improved reliability and higher endurance, which require precise and clear knowledge of the gear tooth stress field during meshing. Approach: This study considered the calculation of maximum stress at gear tooth root when the … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 7,879 accessesView PDFCite
