Research ArticleOpen accessIn the abstractAnalysis of Constituents and Bacteriostatic Activity of Essential Oil Extracted from Sea Buckthorn Seeds by Different MethodsHepeng Zhao, Fuyin Zhao, Qian Xiao et al.Sea buckthorn is a homologous plant listed in Chinese pharmacopoeia. The Essential Oils (EOs) of Sea Buckthorn Seeds (SBTS) are widely used in medicine and health products in China, Russia and other countries. The extraction methods of SBTS with advantages of low cost, high yield and high activity have attracted considerable attention. In this study, the extraction rate, chemical compositions … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 2 · 4 Jun 2021 · 7,483 accessesView PDFCite
Research ArticleOpen accessIn the abstractNovel De-Oiling of Oil-WaterEmmanuel Ewa Ekeng, Jonah Chukwuemeka AgunwambaThe study anchors on developing a mechanistic model for oil-water separation. Over the years, researchers have been working on how to improve the quality of produced water effluent especially from oil and gas operations sent to the receiving waters. Despite the standard set for compliance by regulatory bodies like united nation agency, ministry, departments and other agencies both state and … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 2 Sep 2020 · 6,952 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of Chemical Composition of Extract from Beta Vulgaris Seeds and its Cytotoxic ActivityAiman Konkabayeva, Margarita Ishmuratova, Gulmira Tykezhanova et al.Nowadays, a variety of plants is being investigated with the aim of developing new medicines with improved properties and expanding the range of efficient and safe preparations. Modern studies of representatives of the family Amaranthaceae (Beta vulgaris) have revealed medicinal properties in plants that were used previously only as food. Many medicinal properties are due to the presence of betalains … …OnLine Journal of Biological Sciences, Vol. 21, Issue 2 · 27 May 2021 · 6,225 accessesView PDFCite
Research ArticleOpen accessIn the abstractCurie Point Depth (CPD) Investigation Of Offshore Niger Delta Using High Resolution Aeromagnetic DataOfoha Chimezie Charles, Emujakporue Godwin OmokenuOffshore Niger Delta, Nigeria, is known to be a hub for hydrocarbon exploration within the West Africa region and the world in general. The geologic settings within the Niger Delta province have a proven potential to assist in oil and gas exploration. However, much of the offshore provinces potential remains unknown with respect to the temperature differences using aeromagnetic data. … …Current Research in Geoscience, Vol. 8, Issue 1 · 18 Jan 2019 · 7,815 accessesView PDFCite

Research ArticleOpen accessIn the abstractGrain Size Distribution Characteristics Variation in Oily Contaminated Sandy Soils Due to Long Term Aging Effect in Al-Ahmadi Field at KuwaitHumoud Melfi Aldaihani, Fahad A. Alotaibi, Farraj F. Al-ajmiAlmost three decades on, the negative environmental impacts arising from the burning of over 600 oil wells in Kuwait following the 1991 Gulf War are still evident. At the time of the incident, the Kuwaiti desert region became polluted with hydrocarbon, with a number of ‘oil lakes’ forming, causing critical harm to local land. This paper discusses the shifts in … …American Journal of Applied Sciences, Vol. 15, Issue 10 · 23 Nov 2018 · 8,412 accessesView PDFCite
Technical ReportOpen accessIn the abstractWell Test and PTA for Reservoir Characterization of Key PropertiesOkotie Sylvester, Ikporo Bibobra, Ogbarode Napoleon OgbonThe characterization of a reservoir is a process which starts from the beginning of the field (oil or gas) discovery and continuous to the field’s abandonment. It quantitatively or qualitatively describes the characteristics of the reservoir using data available. In the determination of key well and reservoir parameters for reservoir characterization, it is very vital to understand the flow phases … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 30 Oct 2015 · 8,026 accessesView PDFCite
