Awad, Heba Rashed, Wael K. ElfeilInfectious bursal disease consider a vital threat to poultry industry worldwide and It has special potentiality in Egypt as the country become endemic with several clades from avian influenza from both types highly pathogenic (H5N1 and H5N8) and low pathogenic one (H9N2). The Egyptian government depends on the inactivated vaccine strategy to control avian influenza and any infection with IBD … …American Journal of Animal and Veterinary Sciences, Vol. 13, Issue 2 · 18 May 2018 · 8,479 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Study of the Effects of Soil Salinity on the Growth and Development of Maize (Zea Mays L.) by using Sentinel-2 ImageryShakhislam Uzakbaevich Laiskhanov, Zhassulan Maratuly Smanov, Kulyash Duisenbaevna Kaimuldinova et al.Salinization of soil cover and the constant increase in their area have become one of the most pressing problems year after year for irrigated agriculture regions. The degradation processes caused by the salinity of soils negatively affect the growth and development of food crops. Therefore, this study focused on the effects of soil salinity in the midstream of the Syrdarya … …OnLine Journal of Biological Sciences, Vol. 22, Issue 3 · 15 Aug 2022 · 6,257 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFabrication of Carboxymethyl Cellulose (CMC) Derived from Themeda gigantea Cellulose with Various Concentrations of Sodium MonochloroacetateDaimon Syukri, Heru Suryanto, Anni Faridah et al.The purpose of this study was to determine the properties of Carboxymethyl Cellulose (CMC) obtained from pimping stems (Themeda gigantea). There has yet to be a report on utilizing Themeda gigantea as a source of CMC raw materials. CMC was produced by varying the amount of Sodium Monochloroacetate (SMCA) as a carboxymethylation material. This study consisted of five SMCA treatments, … …OnLine Journal of Biological Sciences, Vol. 25, Issue 1 · 24 Oct 2024 · 5,147 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTransverse Velocity, Transverse Boundary Shear Stress and Flow Deviation in Meandering Open ChannelsYoussef Ismail HafezThis study presents a novel approach for characterizing the mechanics of flow in mildly meandering open channels, specifically focusing on the development of a new vertical distribution equation for transverse velocity. Unlike existing equations in the literature that rely on complex logarithmic or integral forms or infinite series forms, which are impractical for hydraulic engineers, the proposed equation employs ordinary … …American Journal of Environmental Sciences, Vol. 20, Issue 1 · 25 Jul 2024 · 5,058 accessesView PDF Cite

Research ArticleOpen accessIn the abstractContinuous Wavelet Transform Based Spectral Decomposition of 3d Seismic Data for Reservoir Characterization in Oyi Field, se Niger DeltaChukwuemeka Ngozi Ehirim, Andifon Sylvester AkpanContinuous Wavelet Transform (CWT) is one of the most used wavelet transform based spectral decomposition methods in the direct detection of hydrocarbons and as an indicator of stratigraphic variability due to its optimal time-frequency resolution and variable time window requirements. CWT based spectral decomposition was applied on a 3D Post Stack Time Migrated (PSTM) seismic data acquired over a producing … …American Journal of Applied Sciences, Vol. 14, Issue 8 · 28 Apr 2017 · 7,791 accessesView PDF Cite
