Research ArticleOpen accessIn the abstractComparison Between Biological Treatment and Chemical Precipitation for Nitrogen Removal from Old Landfill LeachateLong Tengrui, Anas F. Al-Harbawi, He Qiang, Zhai JunThe study reports the results of a laboratory scale investigation aimed at evaluating the effectiveness of mature municipal landfill leachate treatment by a biological stage (used SBBR as a biological treatment) and Chemical precipitation (Used MAP precipitation (magnesium ammonium phosphate)) to study the nitrogen removal capabilities for treatment of sanitary landfill leachate containing high ammonia concentration, and the comparison between … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 7,032 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptical Properties and Kinetic Behavior of Chlorine in Pure Water and Swimming Pool Water using Surface Plasmon Resonance TechniqueW.Y.W. Yusmawati, W. Mahmood Mat YunusAn optical sensor based on surface plasmon resonance phenomenon for detection of chlorine in pure water and swimming pool water is presented. The measurement was carried out at room temperature using Kretschmann surface plasmon resonance technique. When the air medium outside the metal film is changed to chlorine solution, the resonance angle shifted to the higher value. The shift of … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 7,363 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew Low-Temperature Technology of Producing Calcium Feed Phosphate with MicroelementsJózef HoffmannThe possibility of producing feed calcium phosphates in a way ensuring a low physical water content in the product was investigated in laboratory conditions. For this purpose the process use of a phosphoric acid solution with a higher (than in conventional methods) P2O5 content (53-63% by wt. P2O5) with CaO (molar fraction of 0.5-0.8) and CaCO3 in the phosphoric acid … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,739 accessesView PDFCite
Research ArticleOpen accessIn the abstractStandard Versus Specific Therapy for Chronic Osteomyelitis TreatmentAngela Ingianni, Giorgio Lampis, Samuela Laconi et al.58 patients with chronic osteomyelitis were treated either with a standard therapy or with a specific targeted therapy based on the antibiogram assay. Standard therapy was performed by a 15-day course of a parenteral cephalosporin (usually ceftriaxone) in combination with an aminoglycoside (e.g. netilmicin), followed by oral therapy with a fluoroquinolone (generally ciprofloxacin) for 1 to 3 months; specific therapy … …American Journal of Infectious Diseases, Vol. 3, Issue 3 · 30 Sep 2007 · 6,874 accessesView PDFCite
Research ArticleOpen accessIn the abstractOpen ended-coaxial Cable Measurements of Saturated Sandy SoilsAlberto GodioThe application of electromagnetic methods in the radar and micro-wave frequency band allows the fluid content of soils to be estimated; the heuristic or physically-based models permit to relate the observed electrical permittivity of the soils with the porosity and fluid saturation. The role of the effect of the free water and bound water in the overall electromagnetic behaviour of … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 6,800 accessesView PDFCite
Research ArticleOpen accessIn the abstractLab Tests for the Remediation of a PCE Polluted Site by Means of HRC ReactantMaria Chiara Zanetti, Silvia FioreThe injection of reactants is a remediation technology that may be applied both in the vadose zone and in groundwater. In this work a new reagent is examined for the remediation of the vadose zone and groundwater of an industrial site polluted by perchloroethylene (PCE). The tested reactant is the HRC (Hydrogen Release Compound, Regenesis, USA), a reducing agent which … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 6,911 accessesView PDFCite
Research ArticleOpen accessIn the abstractBio-Safety Technology in Production of Bovine Herpesvirus Type 5 (BoHV-5) Using an Alternative Serum-Free MediumTereza C. Cardoso, Heitor F. Ferrari, Maria Cecília R. Luvizotto, Clarice W. ArnsThe detection and growth of bovine herpes virus type 5 (BoHV-5) was evaluated in three different media without foetal bovine serum or animal protein by infecting three different cell lines. The OPTI-PRO, VP-SFM and RPMI 1640 media were supplemented by L-glutamine, antibiotics added by 5µg of insulin-like growth factor (IGF-I) and used to adapt CER, MDBK and CRIB cells in … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 30 Sep 2007 · 6,991 accessesView PDFCite
Research ArticleOpen accessIn the abstractClinical and Surgical Findings and Outcome Following Rumenotomy in Adult Dairy Cattle Affected with Recurrent Rumen Tympany Associated with Non-Metallic Foreign BodiesZ. Bani Ismail, A. Al-Majali, K. Al-QudahMedical records of 31 adult dairy cows suffering from recurrent rumen tympany for at least 1 month duration that underwent exploratory laparotomy and rumenotomy were reviewed and information was obtained on signalment, history, physical examination findings, laboratory findings and surgical findings. Cases were categorized according to surgical findings into 3 groups. Group 1 (n = 10) included cattle with reticuloruminal, … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 3 · 30 Sep 2007 · 8,927 accessesView PDFCite
Research ArticleOpen accessIn the abstractANN Based DSPIC Controller for Reactive Power CompensationR.A. Jayabarathi, N.B. DevarajanIn India with a power shortage of about 10% of installed capacity, the transmission and distribution losses are relatively high. One of the reasons for the large loss is the excessive reactive loads on the primary distribution feeder. With the right amount of reactive power compensation, as system load varies, line losses can be considerably reduced. The application of Artificial … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 6,851 accessesView PDFCite
Research ArticleOpen accessIn the abstractMulticultural Upper Secondary School Life in Denmark: Identifications, Solidarity and CitizenshipYvonne MørckEducation has played an important role in the development of the Nordic welfare states.
