abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
this study investigated the effects of planning on second-language written production with regard to task type. the participants were 75 iranian learners of english as a foreign language attending a private foreign language institution. they were asked to complete two different types of writing tasks (expository writing task and argumentative writing task) in different planned conditions (indiv...
bleaching process is an essential stage in the refining of vegetable oils and fats. in this process the colour and the primary and secondary oxidation products are removed by the treatment with the acid activated bleaching earth .the aim of this project is to understand the effect of bleaching on the physical characteristics and chemical constituents of neutralized canola and sunflower seed oil...
Objective: Diabetes is the most common metabolic disease. One of the most common problems in diabetic patients is atherosclerotic cardiovascular disease which induced by hyperlipidemia. Also there has been currently great interest in the potential contribution of oxidative stress in development of diabetes complications. The present study was performed to associate between lipid oxidizability a...
objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...
Fish oils, rich in n-3 PUFA, have become one of the most popular dietary supplements worldwide with millions of regular consumers (1). Sales in the USA alone exceed US$ 1 billion annually (2). There is a broad range of benefits claimed for n-3 fish oils including: prevention of CVD (3) , reduced cognitive decline (4) , and the improved management of inflammatory diseases (arthritis , inflammato...
abstract english language learning in iran has become significant in recent years, and english has been included in the curriculum of iranian schools and universities, and considerable attention has been paid to this language in our society. nevertheless, teaching and learning english in iranian schools has not been able to satisfy the specified goals, so different efl institutes have been est...
In this paper, a novel catalyst (MgAl2O4@SiO2-PTA) was proposed for the green oxidation of aliphatic alcohols. The resultant composite was characterized by different techniques, such as X-ray diffraction (XRD), SEM, FT-IR, EDX and Brunauer-Emmett-Teller (BET) surface area analysis. The prepared nanocomposite was used as a catalyst for oxidation of aliphatic alco...
PURPOSE To quantify age-related changes in products of lipid oxidation in human lenses and to relate these changes to membrane hydrocarbon chain structure. Deviation from a well-defined membrane-lipid composition and structure could result in alterations in membrane function and disruption of the homeostasis of the cell. METHODS Infrared spectroscopy was used to detect lipid compositional and...
