Research ArticleOpen accessIn the abstractBacterial Contamination and Resistance to Commonly Used Antimicrobials of Healthcare Workers' Mobile Phones in Teaching Hospitals, Kerman, IranGholamreza Sepehri, Nooshin Talebizadeh, Ali Mirzazadeh et al.Problem Statement: The contamination rates of Health Care Worker's (HCW) mobile phones and resistance to commonly used antimicrobials were evaluated in three teaching hospitals in Kerman, Iran. So, we examined 150 randomly selected HCWs in three teaching hospitals in Kerman, Iran, 2007. For each HCW a sterile swab moistened with sterile water was rotated over the surface of both sides … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 9,773 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Studies of the Determination of Divalent Cadmium, Lead and Copper in the Boiling Medicinal Herbs by Stripping Voltammetry and by Atomic Absorption SpectrometryAhmed Hassan, Jamal A. MayoufCadmium, lead and copper were determined in ten Libyian boiling medicinal herbs samples by differential pulse anodic stripping voltammetry as well as by atomic absorption spectrometry. Voltammetric method was done at Hanging Mercury Dropping Electrode (HMDE) in Briton-Robinson buffer solution of pH ~2.1 at 25± 0.1°C. The sample preparation was carried out by boiling 2.0g of a finely pulverized plant … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,029 accessesView PDFCite
Research ArticleOpen accessIn the abstractAppraisal of Thermal Properties of Mud in the Ariake Sea, JapanM. Azizul Moqsud, Shigenori Hayashi, Yan Jun Du, Daisuke SuetsuguIn order to explore the thermal properties of the Ariake Sea mud and to find out the affecting factors which affect these values, a portable thermal properties analyzer was used. Thermal conductivity, thermal resistivity, thermal diffusivity and volumetric heat capacity of the mud samples collected from both the tidal flat and inside the deep sea were measured in the laboratory. … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 6,966 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Metoprolol and Felodipine in Binary Mixture Using Chemometric-Assisted Spectrophotometric and High-Performance Liquid Chromatographic-UV MethodsHesham Salem, Ola M. AbdallahFour methods were developed for simultaneous determination of metoprolol and felodipine without previous separation. In the first method both drugs were determined using first derivative UV spectrophotometry, with zero crossing measurement at 222 and 235 nm for metoprolol and felodipine, respectively. The second method depends on first derivative of the ratios spectra by measurements of the amplitudes at 250.1 nm … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 8,025 accessesView PDFCite
Research ArticleOpen accessIn the abstractContributions To The Study Of Heavy Metals Concentration Variation In Sedimentable Dusts According To The Distance From The Pollution SourceMariana DOBRA, Vasile VIMAN, Gheorghe VÂTCĂThe environment in areas where geological and mining activities, such as the extraction of ores containing heavy metals, take place, is heavily polluted with dusts resulting from these activities, as well as with residual waters from the mines. Depending on the meteorological conditions, as well as on the conditions under which sedimentable dusts or dusts in suspension are emitted into … …American Journal of Environmental Sciences, Vol. 2, Issue 3 · 30 Sep 2006 · 6,968 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Compressing Ultrasonic Data Algorithm Based on WaveletsMounir Hergli, Jamel Baili, Faouzi Bouslama, Kamel BesbesIn this paper, we propose a novel and effective algorithm for compressing large volumes of data recorded in underwater applications, using a laboratory designed experimental setup. This data represents samples of ultrasonic signals acquired at different geometric positions of a water tank. The proposed algorithm was based on Wavelets and consists of two processing phases including a prefiltering stage using … …American Journal of Applied Sciences, Vol. 2, Issue 12 · 31 Dec 2005 · 7,000 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 · 6,478 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Geosta Addition on Cement-stabilised Chicoco Mud of the Niger DeltaOlujide OmotoshoChicoco is a very soft and extremely compressible organic marine mud found extensively and to considerable depths within the saline tidal flat or mangrove swamp of the Niger delta in southern Nigeria. Natural chicoco is highly undesirable, barely able to support a human of average weight but air-dried chicoco has been used successfully by the indigeneous people for shore protection, … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 7,578 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDetection of IL-17 and IL-23 in Plasma Samples of Children with AutismAmanda Enstrom, Charity Onore, Irva Hertz-Picciotto et al.Interleukin-23 (IL-23) is a survival factor for a newly described population of T lymphocytes, namely Th-17 cells, that secrete IL-17, tumor necrosis factor- alpha (TNFα) and IL-6. It has been shown that Th-17 cells are a pathogenic T cell subset involved in autoimmune and chronic inflammatory diseases. Based on the increasing evidence of immune dysfunction in autism, including possible autoimmune … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 2 · 30 Jun 2008 · 8,223 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordThe Effect of Fluoride and Other Ions on Algae and Fish of Coastal Water of Mediterranean Sea, EgyptM. S. Masoud, W. M. El-Sarraf, A. A. Harfoush, G. F. El-SaidSea grass, marine algae and fish samples were collected from the Egyptian coast of Mediterranean Sea during September 2000 and March 2001. The contents of fluoride and some interfering ions (calcium, magnesium, sulphate, phosphorus and some heavy metals) ions and their concentration factors were determined in the dried samples. Fluoride contents in macrophytes, algae, muscle of fish samples were ranged … …American Journal of Environmental Sciences, Vol. 2, Issue 2 · 30 Jun 2006 · 7,265 accessesView PDFCite
