Research ArticleOpen accessIn the abstractCurrent Approaches for the Prevention of Surgical Site InfectionsSander Florman, Ronald Lee NicholsSurgical site infections (SSIs) are the most common type of nosocomial infection among surgical patients and are commonly caused by the patients’ own microbial flora. The prevalence of SSI is a major concern because of the associated increase in the incidence of morbidity and mortality, length of hospitalization and cost of care for postoperative patients. Key factors that determine whether … …American Journal of Infectious Diseases, Vol. 3, Issue 1 · 31 Mar 2007 · 7,824 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffective Coagulation Technology for Treatment of Grease Filter WashwaterAbdel E. Ghaly, A. Snow, B.E. FaberThe treatment of grease filter washwater by chemical coagulation and sedimentation using different dosages of aluminum sulfate was investigated. Pollutant removal efficiency was measured in terms of total solids, pH and optical density. The process was found to be effective at the room temperature and the filter washwater pH (9.5). The optimum aluminum sulfate dosage was 2 g/L. The treatment … …American Journal of Environmental Sciences, Vol. 3, Issue 1 · 31 Mar 2007 · 6,816 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effects of Short or Long Term FGA Treatment with or without eCG on Reproductive Performance of Ewes Bred Out-of-seasonMustafa Q. Husein, Mohammed M. Ababneh, Dia S. Abu-RumanThe objective was to evaluate the effects of intravaginal FGA sponges inserted for 4 or 12 days with or without eCG on reproductive performance of ewes out-of-season. Forty-eight anestrous ewes were assigned in equal numbers to four treatments in a 2x2 factorial design. Ewes were administered with FGA sponges on May 17 for 12 days (12-day-FGA-eCG and 12-day-FGA groups, n= … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 1 · 31 Mar 2007 · 7,485 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhytoremediation of Anaerobic Digester Effluent for Water Purification and Production of Animal FeedA. E. Ghaly, H.A. FaragThe application of phytoremediation for purification of an anaerobically treated dairy manure and production of forage crops was investigated. Four crops (two cereals and two grasses) were examined for their ability to grow hydroponically and to remove pollutants (nutrients) from dairy wastewater. The preliminary experiments showed that timothygrass and orchardgrass did not perform well as aquatic plants. Only 24 and … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 1 · 31 Mar 2007 · 8,201 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn HIV/AIDS Model with Variable Force of Infection and its Application to the Epidemic in UgandaFlugentius Baryarama, Joseph Y.T. Mugisha, Livingstone S. LuboobiAn HIV/AIDS model is formulated with variable force of infection for the adult population. Its actions are reduced to a prevalence equation that is a non-logistic equation whose explicit solution is derived. The implications of applying the solution to the evolution of the HIV/AIDS epidemic are discussed with respect to the positive boundedness of the coefficients. Prevalence projections are presented … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,964 accessesView PDFCite
Research ArticleOpen accessIn the abstractGender Differences in Baseline Levels of Vascular Endothelial Growth Factor in the Plasma of Alaskan Sled DogsScott W. Kemp, Arleigh J. Reynolds, Lawrence K. DuffyAngiogenesis and vasculogenesis are two very important processes in the development and maintenance of mammalian health. In sled dogs, the angiogenic role is to supply and support tissue with ample vasculature, thus providing a route of access for the transportation of essential nutrients, including oxygen and the removal of waste in a sustained fashion. VEGF has been shown to be … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 2 · 30 Jun 2005 · 6,318 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntibacterial Effect of Untreated and Treated (Decolorized) Dyes by Agricultural WastesSibel Kahraman, Pelin YalcinToxicity (antibacterial effect) of untreated and treated (decolorized) dyes on a soil bacterium, Pseudomonas aeruginosa was determined. Low cost and easily available two agricultural residues (cotton stalk and apricot seed) as biosorbents were used to remove Astrazone Black and Astrazone Yellow from aqueous solution. The removal of these dyes with agricultural wastes reduced the toxic effect on P. aeruginosa. This … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 1 · 31 Mar 2005 · 7,260 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Modeling of Wastewater Oxidation under Microgravity ConditionsBoyun Guo, Donald W. Holder, David S. SchechterVolatile removal assembly (VRA) is a module installed in the International Space Station for removing contaminants (volatile organics) in the wastewater produced by the crew. The VRA contains a slim pack bed reactor to perform catalyst oxidation of the wastewater at elevated pressure and temperature under microgravity conditions. Optimal design of the reactor requires a thorough understanding about how the … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 6,888 accessesView PDFCite
Research ArticleOpen accessIn the abstractIsolation and Identification of a Bioflocculant-Producing Strain and Application in Rice Vinegar ClarificationWeilian Hu, Dehui DaiA bioflocculant-producing bacterium S-3# was isolated from fresh sand bones 40-50 cm underground in the desert region of China’s Ningxia Province. It was identified as Paenibacillus sp. based on 16S rDNA sequence along with its biochemical and morphological characteristics. Chemical analysis found that the bioflocculant from S-3# is mainly composed of extracellular polysaccharide. Researchers observed no noticeable change (above 91%) … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 4 · 30 Dec 2020 · 5,924 accessesView PDFCite
EditorialOpen accessIn the abstractProtecting crop species from biotic and abiotic constraints in the era of Global Change: are we ready for this challenge?Marco Landi, Giovanni BenelliReliable and affordable supply of food is of crucial importance to the progress and stability of human societies. During the last century, we have assisted to an extraordinary increase of crop yields, especially for the most widespread and consumed crop species, such as rice, wheat, corn and soybean. The Broadbalk experiment, one of the oldest continuous agronomic experiments in the … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 2 · 4 Jun 2016 · 8,399 accessesView PDFCite
