Research ArticleOpen accessIn the abstractMissouri Spring Freeze Event and Crop Loss Analysis for the Years 1982-2015Mirza Mohd Shahriar Maswood, Ali Koleiny, Scott Nickell et al.A spring freeze is an unexpected freeze event occurring in late spring that can result in severe domestic crop loss. These events coincide with seasonal weather conditions that promote early crop development. As a consequence, early growth is most susceptible to freeze damage. Spring temperature fluctuations pose significant threat to crop yield and growth, when compared to onsistently cold springtime … …American Journal of Agricultural and Biological Sciences, Vol. 13, Issue 1 · 4 May 2018 · 8,737 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAn Informetric Analysis of Studies on Influenza Vaccines and VaccinationVadim Nikolaevich Gureyev, Nikolay Alekseevich Mazov, Tatyana Nikolaevna Ilyicheva, Sergei Ivanovich BazhanInfluenza is one of highly contagious acute virus diseases that primarily affects respiratory ways. Annual seasonal epidemics afflict approximately 15% population worldwide and lead to 250,000–500,000 deaths each year. That is why studies on influenza vaccines and vaccination that prevent spreading of the virus remain highly important. This paper presents the results of informetric analysis of publications on influenza vaccine … …OnLine Journal of Biological Sciences, Vol. 17, Issue 4 · 13 Dec 2017 · 7,278 accessesView PDF Cite

Case ReportOpen accessIn the abstractEvaluation of Seasonal Autoregressive Integrated Moving Average Models for River Flow ForecastingKassahun Birhanu Tadesse, Megersa Olumana Dinka, Tena Alamirew, Semu Ayalew MogesReservoir operation policies cannot be functional in instant decision making without forecasting the future reservoir inflows. For forecasting inflows into reservoirs with only hydrological data is available like Koga irrigation dam, multivariate forecasting models cannot be used to generate accurate river flow information. As a result, an evaluation of univariate Seasonal Autoregressive Integrated Moving Average (SARIMA) models was done for … …American Journal of Environmental Sciences, Vol. 13, Issue 5 · 28 Sep 2017 · 7,891 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInfluenza Surveillance in Russia Based on Epidemiological and Laboratory Data for the Period from 2005 to 2012Sominina Anna, Elena Burtseva, Mikhail Eropkin et al.Exchange of information on and sharing of influenza viruses through the GISRS network has great significance for understanding influenza virus evolution, recognition of a new pandemic virus emergence and for preparing annual WHO recommendations on influenza vaccine strain composition. Influenza surveillance in Russia is based on collaboration of two NICs with 59 Regional Bases. Most epidemiological and laboratory data are … …American Journal of Infectious Diseases, Vol. 9, Issue 3 · 14 Oct 2013 · 8,761 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSeasonal Autoregressive Integrated Moving Average Model for Precipitation Time SeriesYan Wang, Xinghua Chang, Meng Gao, Xiyong HouPredicting the trend of precipitation is a difficult task in meteorology and environmental sciences. Statistical approaches from time series analysis provide an alternative way for precipitation prediction. The ARIMA model incorporating seasonal characteristics, which is referred to as seasonal ARIMA model was presented. The time series data is the monthly precipitation data in Yantai, China and the period is from … …Journal of Mathematics and Statistics, Vol. 8, Issue 4 · 20 Feb 2013 · 12,662 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSeasonal ARIMA for Forecasting Air Pollution Index: A Case StudyMuhammad Hisyam Lee, Nur Haizum Abd. Rahman, Suhartono et al.Problem statement: Both developed and developing countries are the major reason that affects the world environment quality. In that case, without limit or warning, this pollution may affect human health, agricultural, forest species and ecosystems. Therefore, the aim of this study was to determine the monthly and seasonal variations of Air Pollution Index (API) at all monitoring stations in Johor. … …American Journal of Applied Sciences, Vol. 9, Issue 4 · 14 Feb 2012 · 10,332 accessesView PDF Cite

Research ArticleOpen accessIn the abstractLimnological Studies on the Wetland Lake, Al-Asfar, with Special References to Heavy Metal Accumulation by FishGehan H. Fahmy, Adel A. FathiProblem statement: Al-Asfar Lake is one from the important shallow wetland lakes. It is located on the eastern region of Saudi Arabia, Al-Hassa Province. However, much of their limnology and its biotic information are still unknown to the scientific community. The study aims to follow variations in physico-chemical characteristics, phytoplankton and to determine the sort of pollutants such as heavy … …American Journal of Environmental Sciences, Vol. 7, Issue 6 · 31 Dec 2011 · 9,947 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTime Series Analysis of Rainfall and Temperature Interactions in Coastal CatchmentsGurudeo Anand Tularam, Mahbub IlaheeProblem statement: As a result of climate change more work is now being done on climate indices such as SOI, rainfall, temperature and so on. The research concerning rainfall and temperature variations in coastal tropical and subtropical catchments as noted by the dated references in this study shows a lack of attention. The authors examined long term data from coastal … …Journal of Mathematics and Statistics, Vol. 6, Issue 3 · 30 Sep 2010 · 15,828 accessesView PDF Cite

Research ArticleOpen accessIn the abstractWater Quality and Planktonic Communities in Al-Khadoud Spring, Al-Hassa, Saudi ArabiaAdel A. Fathi, Mohammed A. Al-KahtaniProblem statement: Al-Khadoud spring is one of the most important water resources in Al- Hassa Governorate, Saudi Arabia. However, much of its biotic information is still unknown. This study presented preliminary ecological information of this aquatic body. The aim of this research was to study the water characteristics and the planktonic organisms inhibiting Al-Khadoud spring and its irrigational channels for … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,058 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSeasonal Variations of n-6: n-3 Ratios and Fatty Acid Compositions in Foot and Tissue of Chiton lamyi in a High Primary Productivity AreaNooshin Sajjadi, Peyman Eghtesadi-Araghi, Shahla Jamili et al.Problem statement: Fatty acid content and composition in mollusks is a function of their feeding diversity. Chabahar bay located in the northern part of Oman sea in Indian ocean provides high rates of primary productivity and a diverse food source for mollusks in this area. Identification of fatty acid compositions of Chiton lamyi and study their seasonal changes in the … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,198 accessesView PDF Cite
