Research ArticleOpen accessIn the abstractThe Changes of Some Electrolytes after Two Months ActivityM. J. Pourvaghar, A. R. ShahsavarSome investigators have speculated that sodium chloride losses in sweat associated with net dehydration may lead to the observed hyponatremia after prolong strenuous exercise. The effects of altered hydration can influence athletes cognitively in addition to physically. In this research, rest alterations of sodium and potassium of blood serum have been investigated. The subjects were male students who have been … …Journal of Social Sciences, Vol. 4, Issue 4 · 31 Dec 2008 · 7,935 accessesView PDFCite
Research ArticleOpen accessIn the abstractProgressive Resistance Training on Elderly HIV+ Patients: Does it Work?Paula Maria Loiola De Souza, Wilson Jacob Filho, José Maria Santarém et al.Elderly people present significant alterations on body composition and physical fitness, compromising their quality of life. Chronic diseases, including HIV/AIDS, worsen this situation by increasing aging effects on body composition and muscle strength. Resistance exercises are prescribed by major health organizations for improving fitness and promoting a shift towards a healthier and more independent aging. In addition, recovering strength and … …American Journal of Infectious Diseases, Vol. 4, Issue 4 · 31 Dec 2008 · 6,740 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeochemical Distribution of Trace Metals and Assessment of Anthropogenic Pollution in Sediments of Old Nakagawa River, Tokyo, JapanH.M. Zakir, Naotatsu Shikazono, Kazuo OtomoThe geochemical distributions of cadmium (Cd), copper (Cu), chromium (Cr), lead (Pb) and zinc (Zn) were examined in sediments collected from Old Nakagawa River (NR), Tokyo, Japan. A widely used 5-step sequential extraction procedure was employed for the fractionation of the metals and the concentrations were measured in the liquid extracts by inductively coupled plasma mass spectrometry (ICP-MS). The association … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 7,453 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Efficient Production of Oligosaccharides by a Reaction using Whole Mammalian Cells as BiocatalystsTomohisa Kato, Rie Mitsumori, Kenichi HatanakaProblem statement: Mammalian cells were used for the production of oligosaccharides by saccharide primer method. However, because cells in culture are used, productivity of oligosaccharides is low. Approach: In saccharide primer method employing cells under culture, glycosylation was performed only by mixing the collected cells in reaction mixtures. Saccharide primer, 12-azidododecyl β-lactoside that mimics lactosylceramide (LacCer), was incubated with various … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2008 · 6,439 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Grazing Sorghum Stubble on Soil Physical Properties and Subsequent Crop PerformanceB.J. Radford, D.F. Yule, M. Braunack, C. PlayfordTwo grazing trials were conducted on a Vertosol in central Queensland to assess the effects of stubble grazing by cattle on soil properties and subsequent crop performance. Two adjacent contour bays were selected for two treatments (grazed and ungrazed) in each trial. Both trials were conducted following a grain sorghum crop. In trial 1 (during 1996) the surface soil was … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 4 · 31 Dec 2008 · 8,154 accessesView PDFCite
Research ArticleOpen accessIn the abstractTaxonomic Significance of ISTR to Discriminate Species in AgavaceaeMartha Isabel Torres-Morán, Norma Almaraz-Abarca, Ana Paulina Velasco-Ramírez et al.Family Agavaceae is endemic of American Continent. From the around 300 species recognized in this family, 217 occur in Mexico. Relevant ethnobotanic relationships among Agavaceae and the several native human cultures of the American Continent have been established since prehispanic times. Agave is one of the most important genus in that family due to its great diversity and abundance, mainly … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 4 · 31 Dec 2008 · 8,189 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Bandwidth Analysis of Fault-Tolerant Multistage Interconnection NetworksR. Aggarwal, L. KaurThe design of a suitable interconnection network for inter-processor communication is one of the key issues of the system performance. In this study a new irregular interconnection network IABN (Irregular Augmented Baseline) has been proposed. IABN is designed by modifying existing ABN (Augmented Baseline Network). ABN is a regular multi-path network with limited fault tolerance. IABN provides three times more … …Journal of Computer Science, Vol. 4, Issue 11 · 30 Nov 2008 · 6,830 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Minimal Duration Essential for Isolation of Humic Acids From Soils in Forest Restoration ProgrammesMohd Ramzan Nur Hanisah, Osumanu Haruna Ahmed, Kasim Susilawati et al.This study was conducted to investigate whether a simple and rapid method could be developed for extracting, fractionating and purifying soil HA in forest rehabilitation programmes. Humic acids from 10 g of soil were extracted with 100 mL of 0.10 M NaOH. Different extraction periods (4, 8, 12, 16, 20 and 24 h) were tested. Samples were centrifuged (16,211 G … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 3 · 30 Sep 2008 · 8,173 accessesView PDFCite
Research ArticleOpen accessIn the abstractNarrow-band ultraviolet B and Conventional UVB phototherapy in Psoriasis: a Randomised Controlled TrialYan Yuehua, Ahmad T. Khalaf, Zhai Xiaoxiang, Wang XinggangThe narrow-band (NB-UVB) was developed for use in phototherapy, as an alternative to a broad-band UVB source and to photochemotherapy, both of which have significant side effects and carry a risk of carcinogenesis. NB-UVB is a new phototherapy option that has proved to be particularly effective at clearing psoriasis vulgaris, with a reduced capacity to produce erythema. This study was … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,950 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Improved Handwritten Tamil Character Recognition System using Octal GraphR. J. Kannan, R. PrabhakarProblem Statement: Handwriting recognition has attracted voluminous research in recent times. The segmentation and recognition of the characters from handwritten scripts incorporates considerable overhead. Almost all the existing handwritten character recognition techniques use neural network approach, which requires lot of preprocessing and hence accomplishing these problems using neural network is a tedious task. Approach: In this study we propose a … …Journal of Computer Science, Vol. 4, Issue 7 · 31 Jul 2008 · 7,405 accessesView PDFCite
