Research ArticleOpen accessIn the abstractExtracts of Pumpkin (Cucurbita pepo L.) Seeds Suppress Stimulated Peripheral Blood Mononuclear Cells in vitroChristiana Winkler, Barbara Wirleitner, Katharaina Schroecksnadel et al.In the traditional medicine in North America and Mexico, pumpkin seeds have been used as an anthelmintic agent and for supportive treatment in functional disorders of the bladder. Also anti-inflammatory and cardioprotective activity of pumpkin seeds is discussed. Three different extracts of pumpkin seeds were prepared and effects were investigated in unstimulated human peripheral blood mononuclear cells and in cells … …American Journal of Immunology, Vol. 1, Issue 1 · 31 Mar 2005 · 10,717 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Rainfall-runoff Models to Zard River Catchment'sM. B. Rahnama, G. A. BaraniRainfall-runoff models are nonlinear processes according to the sequential and spatial distribution of the rainfall. So, it is difficult to explain the response of catchments systems with the simple models. In the present work simulation of the rainfall-runoff processes have been carried out by the Artificial Neural Networks (ANN) and the HEC-HMS models. The ANN models of Multi Layer Perceptron … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 6,535 accessesView PDFCite
Research ArticleOpen accessIn the abstractStatistical Verification of Folk Medicinal Potentiality of Wild Dicot Aquatic Plants in JordanS. Al-Qura'nThis study describes a floristic study of Jordan with its environs. The study was carried out during 2001-2003 and 287 aquatic dicot samples were collected and photographed in the field. After the identification of the specimens, the total wild aquatic dicot species have been determined as 87 species belonging to 59 genera and 33 plant families were presented in investigated … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 6,483 accessesView PDFCite
Research ArticleOpen accessIn the abstractMethyltert-butyl Ether (MTBE) Degradation by a Microbial ConsortiumS. B. Mortazavi, A. Nikpey, A. Rezaee et al.Methyl tert-butyl ether (MTBE) is added to reformulated gasoline to meet the 1990 Clean Air Act directives. Widespread use of MTBE in gasoline has resulted in groundwater contamination. Because of its undesirable effects on drinking water and ecologically harmful effects, MTBE removal has become a public health and environmental concern. In this study, we have isolated a mixed bacterial culture … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 7,004 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of the Ozonation Pre-treatment for Biodegradation of Aqueous Solutions of Methyltert-Butyl EtherM. Sadeghi, A. Mesdaghinia, A. Badkoubi et al.The effectiveness of ozone treatment for improving the biodegradability of recalcitrant pollutants has been proved by investigating the ozonation reaction of Methyl tert-butyl ether (MTBE) a bioresistant gasoline oxygenate. Laboratory scale experiments have been carried out, at room temperature, by bubbling, for 120 min, ozonated air (3.4 ppm min-1 ) into 3 liter of an alkaline (pH=11.5) aqueous solution (100 … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 6,469 accessesView PDFCite
Research ArticleOpen accessIn the abstractField and Laboratory Suction- Soil Moisture Relationship of Unsaturated Residual SoilsBujang B.K. Huat, Faisal H. Ali, A. AbdullahSoils located above the groundwater table such as residual soils are generally unsaturated and possess negative pore-water pressures. A soil-water (moisture) characteristic curve (SWCC) that relates the water content of a soil to matric suction is an important relationship for the unsaturated soil mechanics. The SWCC essentially shows the ability of an unsaturated soil to retain water under various matric … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 7,043 accessesView PDFCite
Research ArticleOpen accessIn the abstractFunctional Planning Criterion of Forest Road Network Systems According to Recent Forestry Development and Suggestion in TurkeyMurat Demir, Mesut HasdemirEnvironment of the conscious of puclic opinion is increase recent years. When making use of the forest ecosystem for various purposes, care must be taken not to spoil the forest structure. To achieve this, forests must be used according to forestry techniques. Forest roads planning standarts (slope, width, pavement, drainage etc.) are different in production forests, forestation, national park and … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 7,286 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntioxidant, Free Radical Scavenging and Metal Chelating Characteristics of PropolisHikmet Geckil, Burhan Ates, Gokhan Durmaz et al.This study was undertaken to determine the reducing characteristics, metal chelating capability, anti-lipid peroxidative and antiradical properties of propolis compared to two widely used artificial antioxidants, Butylated Hydroxyanisole (BHA) and Butylated Hydroxytoluene (BHT). The water and ethanol extracts of propolis showed significantly a different degree of metal chelating, radical scavenging activity and reducing power. In general, ethanol extracts of propolis … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 1 · 31 Mar 2005 · 9,095 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpectrofluorimetric, Atomic Absorption Spectrometric and Spectrophotometric Determination of Some FluoroquinolonesHesham SalemSimple, accurate, sensitive and selective spectrofluorimetric, atomic absorption spectrometric and spectrophotometric methods are described for the quantitative determination of ten fluoroquinolones (amifloxacin, ciprofloxacin hydrochloride, difloxacin hydrochloride, enoxacin, enrofloxacin, lomefloxacin hydrochloride, levofloxacin, norfloxacin, ofloxacin and pefloxacin mesylate). The first method was a spectrofluorimetric method in which samples of the studied drugs in 0.1 N H2SO4 showed native fluorescence at 450 nm … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 7,320 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Investigation into the Use of the Least Significant Bit Substitution Technique in Digital WatermarkingKevin Curran, Xuelong Xi, Roisin ClarkeDigital imaging companies lose revenue each year to people who are illegally copying and using their images. One prevention mechanism is to digitally encode images making it difficult for others to copy. This could be done using digital fingerprinting or simply adding a visible watermark. The information is hidden in a way that should not attract attention, but make it … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 7,471 accessesView PDFCite
