Research ArticleOpen accessIn the abstractDRYING METHODS AND THEIR IMPLICATION ON QUALITY, QUANTITY AND ANTIMICROBIAL ACTIVITY OF THE ESSENTIAL OIL OF LAURUS NOBILIS L. FROM MOROCCOKhadija Dahak, Hafida Bouamama, Fatiha Benkhalti, Moha TaourirteThe effects of various methods of drying on the chemical quality and antimicrobial activity of the essential oil of Laurus nobilis were studied. The most prominent component in the air-dried, fresh leaf and microwave-dried leaf oils is 1,8 Cineole (58,8, 35.62 and 42,9% respectively). The essential oil has undergone significant chemical transformation in its monoterpenoids when the leaves of plant … …OnLine Journal of Biological Sciences, Vol. 14, Issue 2 · 20 Mar 2014 · 7,553 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOlfactory Responses of the Asiatic Citrus Psyllid (Diaphorina citri) to Mineral Oil-Treated Mandarin LeavesMofit Eko Poerwanto, Y. Andi Trisyono, G. Andrew C. Beattie et al.Problem statement: Evidence of rejection or acceptance by phytophagous pests of citrus plants treated with mineral oils suggests that impacts of oils may be related to detection by olfactory and/or contact chemoreceptors of repellent oils or plant volatiles. Alternatively, the oils may mask or suppress attractant host plant volatiles. To date, no studies have reported that oils elicit an olfactory … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 30 Jan 2012 · 8,785 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComposition-Explicit Distillation Curves of Waste Lubricant Oils and Resourced Crude Oil: A Diagnostic for Re-Refining and EvaluationLisa Starkey Ott, Beverly L. Smith, Thomas J. BrunoProblem statement: We have recently introduced several important improvements in the measurement of distillation curves for complex fluids. The modifications include a composition-explicit data channel for each distillate fraction and temperature measurements that are true thermodynamic state points that can be modeled with an equation of state. The composition-explicit information is achieved with a sampling approach that allows precise qualitative … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 8,106 accessesView PDF Cite

Research ArticleOpen accessIn the abstractProduction of Biodiesel by Enzymatic Transesterification: ReviewA.E. Ghaly, D. Dave, M.S. Brooks, S. BudgeProblem Statement: The research on the production of biodiesel has increased significantly in recent years because of the need for an alternative fuel which endows with biodegradability, low toxicity and renewability. Plant oils, animal fats, microalgal oils and waste products such as animal rendering, fish processing waste and cooking oils have been employed as feedstocks for biodiesel production. In order … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 2 · 30 Jun 2010 · 21,478 accessesView PDF Cite

Research ArticleOpen accessIn the abstractProduction, Yield and Derivatives of Volatile Oils from Eastern Redcedar (Juniperus Virginiana L.)Elif Semen, Salim HizirogluEastern redcedar (Juniperus virginiana L.) is one of the most widely distributed indigenous conifers in southern states including Oklahoma, Arkansas and Texas. Eastern redcedar is also an important source of the volatile oils. This specie adversely influences the environment resulting in degrading grassland, displacement of native plant population and increasing wildlife hazard. Range-grown eastern redcedar has a poor quality. However, … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 6,760 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Ability of Bipolaris Sorokiniana Isolated from Spring Barley Leaves to Survive in Plant Residuals of Different CropsYerlan Dutbayev, Aidana Kharipzhanova, Nadira Sultanova et al.Spring barley is an important high-value crop globally. However, it is highly susceptible to soil-borne diseases in Kazakhstan and the world. Bipolaris sorokiniana (Sacc.) Shoemaker is the most important soil-borne pathogen that causes root rot and spot blotch diseases in cereal crops. This study aimed to evaluate the ability of B. sorokiniana isolated from spring barley leaves to survive in … …OnLine Journal of Biological Sciences, Vol. 22, Issue 3 · 27 Jul 2022 · 6,136 accessesView PDF Cite

Research ArticleOpen accessIn the abstractExpanding the Rapeseed Cultivation Area in the South and South-Eastern Regions of Kazakhstan with the Introduction of its Winter VarietyGaliolla T. Meiirman, Sakysh T. Yerzhanova, Serik S. Abayev et al.The paper examines the data on 86 rapeseed samples of various ecological and geographical origins, which were subjected to a long-term selection study with the criterion of winter hardiness to create a new Kazakhstani variety of winter rapeseed. For selection, plant indicators are used in terms of the number of leaves (at least 7), the diameter of the root collar … …OnLine Journal of Biological Sciences, Vol. 22, Issue 1 · 11 Feb 2022 · 6,585 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIdentification and Pathogenicity of the Soybean Root Rot Pathogen in Arid ConditionsNurlan Kuldybayev, Yerlan Dutbayev, Olga Konstantinova et al.Soy is an important oilseed crop in Kazakhstan. However, its yield is significantly reduced due to an increase in the development of fungal diseases with soil infection. This study aims to identify the root rot pathogen in soybean varieties in Western Kazakhstan and assess its pathogenicity. Samples of soybean roots to determine the root rot pathogen were selected at the … …OnLine Journal of Biological Sciences, Vol. 23, Issue 2 · 14 Apr 2023 · 5,528 accessesView PDF Cite
