Research ArticleOpen accessIn the abstractModeling Winter Hardiness Formation in Winter Wheat PlantsDaria Blyshchyk, Anatoliy Polevoy, Pavel FeoktistovA dynamic model, which describes the growth processes, plant development and the passing of the two phases of the autumn hardening under the influence of agrometeorological conditions in autumn, was developed. The model illustrates effects of intensity of Photosynthetically Active Radiation (PAR), sunlight levels, air temperature and soil moisture on the increment of reserves of photosynthesis products and soluble carbohydrates … …American Journal of Agricultural and Biological Sciences, Vol. 15, Issue 1 · 9 Mar 2020 · 7,209 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of the Earth's Surface State by Unsupervised Classification: Case of Vegetated, Aquatic and Mineral SurfacesJean-Claude Okaingni, Sié Ouattara, Adles Kouassi, Alain ClémentIn this study, we propose an unsupervised classification scheme based on the Dempster-Shafer Theory (TDS) and the Dezert-Smarandache Theory (DSmT) to characterize vegetated, aquatic and mineral surfaces. From pre-processed ASTER satellite images (georeferencing, geometric correction and 15 m re-sampling), neo-channels were produced by determining the spectral indices NDVI, MNDWI and NDBaI, considered as sources of information for classification of a … …American Journal of Applied Sciences, Vol. 15, Issue 7 · 27 Aug 2018 · 8,183 accessesView PDFCite
Research ArticleOpen accessIn the abstractDescriptive Epidemiological, Clinical and Microbiological Features of Infective Endocarditis at a University Hospital in Saudi ArabiaReham Kaki, Nabeela Al-AbdullahInfective Endocarditis (IE) still remains a serious disease. The treatment and pathology still remain unclear. In this study, we sought to clarify the epidemiology and treatment of IE in a teaching hospital in Saudi Arabia. In this study, we sought to conduct a retrospective investigation of all adult patients who were treated for IE at our hospital and determine the … …American Journal of Infectious Diseases, Vol. 14, Issue 2 · 28 May 2018 · 8,364 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Needle-Leaved Species in Increasing the Risk of Fire by Using Remote Sensing, Case Study: Forests of Golestan, IranAkram Karimi, Sara Abdollahi, Hamid Reza Kabiri Balajadeh et al.The present research was conducted to determine the sensitivity of needle-leaved species compared to broad-leaved in causing a natural fire in Golestan province. Vegetation and moisture stresses of plants were studied in both needle and mixed leaved forest the fire occurred in 2010-2014. In order to examine the normal condition of each indicator, the time series was produced from 2000 … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 30 Mar 2018 · 7,851 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Absorbing Agent on Moisture Reserves of Winter Wheat in the Conditions of Semiprovided Dry Farming Land of the South-East of KazakhstanLaila Klimovna Tabynbayeva, Serik Barmenbekovich Kenenbayev, Meiramgul Shagievna Suleimenova et al.In the conditions of dry-land farming, the leading factor of productivity, which is minimal, is moisture. Soil moisture directly influences the growth of plants by means of aeration, transfer of nutrient substances, absorption and transformation. The main crop acreage of the spike cereals in the south-east of Kazakhstan is located in dry farming lands that are characterized as dry and … …OnLine Journal of Biological Sciences, Vol. 17, Issue 2 · 27 May 2017 · 7,407 accessesView PDFCite
Research ArticleOpen accessIn the abstractModels of Winter Wheat Yield Based on Calcareous Chernozem Fertility ParametersOlga A. Biryukova, Dmitry V. Bozhkov, Tatiana M. Minkina et al.The use of polyelement diagnostics and regression analysis for predicting the yield of winter wheat at different stages of vegetation is considered. It has been established that the prediction and integrated assessment of grain yield and quality should be performed with consideration for the balance of macro-and micronutrients in the grain and the aboveground biomass of plants. Possibility of predicting … …American Journal of Agricultural and Biological Sciences, Vol. 10, Issue 4 · 1 Jan 2016 · 7,674 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Fungal Communities in Limed and Unlimed Lands Contaminated with Metals: Phospholipid Fatty Acid (PLFA) Analysis and Soil RespirationKassandre Goupil, Kabwe K. Nkongolo, Sabah NasserullaNorthern Ontario (Canada) especially the Greater Sudbury region is highly known for its nickel, copper and other metal deposits. The mining, roasting and smelting of these elements have caused disastrous effects on the vegetation and overall environment. Dolomitic lime which contains calcium and magnesium carbonate was applied to soils from 1980 to 1995 at different locations across Northern Ontario. The … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 2 · 26 May 2015 · 8,100 accessesView PDFCite
Research ArticleOpen accessIn the abstractDETECTION OF LAND USE AND LAND COVER CHANGES IN DIRAB REGION OF SAUDI ARABIA USING REMOTELY SENSED IMAGERIESR. Madugundu, K. A. Al-Gaadi, V. C. Patil, E. TolaKnowledge of Land Use and Land Cover (LULC) changes is important for many planning and management activities. It is thought to be an essential element for modeling and understanding the major land forms, especially in arid regions like Saudi Arabia. This study investigates the LULC changes in Dirab region of Saudi Arabia between 1980 and 2010, using Landsat TM/ETM+images. After … …American Journal of Environmental Sciences, Vol. 10, Issue 1 · 30 Jan 2014 · 8,018 accessesView PDFCite

Research ArticleOpen accessIn the abstractEMPIRICAL DETERMINATION OF THE AVERAGE ANNUAL RUNOFF COEFFICIENT IN THE MEDITERRANEAN AREAGiovanni Grillone, Giorgio Baiamonte, Francesco D’AsaroRunoff estimation in ungauged basin is a challenge for the hydrological engineers and planners. For any hydrological study on an ungauged basin, a methodology has to be appropriately selected for the determination of runoff at its outlet. Several methods have been used to estimate the basin runoff production. In this study the empirical Kennessey method to determine average annual runoff … …American Journal of Applied Sciences, Vol. 11, Issue 1 · 5 Dec 2013 · 8,225 accessesView PDFCite
