This paper presents results of experimental work carried out to study the centrifugal dewatering behaviors of superabsorbent hydrogels. Taking the creep deformation of the hydrogels into consideration and assuming that the mechanical properties of gel network can be represented by Terzaghi–Voigt combined model, the basic differential equation exp

Oil palm industry has an important role in contributing to the Malaysian economy. Several million tonnes of crude palm oil is produced annually and approximately, about 10 million tonnes of palm oil mill effluent (POME) (highly polluted organic effluent) is generated every year. Citric acid is a commercially valuable product widely used in many ind

ازداد الاهتمام على المستوى العالمي منذ السبعينيات من القرن العشرين بتعليم اللغات الأجنبية لأسباب عديدة يرجع بعضها إلى التواصل المستمر بين الشعوب، وتطور وسائل الاتصال الحديثة، والتأثر بالمع�

Bioprotein production is one of the most promising breakthroughs of biotechnological innovations. Due to its increasing demand, the efficient strains, substrate and method must be used for high yield product. In this study, screening of five different cerivisiea, Mucor hiemalis and Thricoderma harzianum, was done for bioprotein production by liquid

Abstract—Eigenvector methods are gaining increasing acceptance in the area of spectrum estimation. This paper presents a successful attempt at testing and evaluating the performance of two of the most popular types of subspace techniques in determining the parameters of multiexponential signals with real decay constants buried in noise. In partic

(13) C – urea breath test (UBT) is sensitive and specific for detection of Helicobacter pylori (H. pylori) infection. Gastric biopsy culture for H. pylori confirms the diagnosis. Here, we analyzed data of all patients who were investigated for H. pylori infection using both tests throughout the year 2005.Int. Med J Vol. 6 No 2 December 2007 Incid

In order to improve quality and productivity among American companies, Malcolm Baldrige National Quality Award (MBNQA) was launched by the National Institute of Standards and Technology (NIST) under the Department of Commerce of US government in 1987. Over the years, the award has been proved to be effective in improving companies’ market share,

Internet technology has been used by most of the organizations in the world today. One of the primary vehicles of information gathering and dissemination in today’s world is organizational website. This research evaluates the performance of the present TV3 (a popular private television station in Malaysia) website. By means of an on-line survey a

Canada has a huge wind power potential of more than 28,000 MW, which represents a significant environmentally benign sustainable energy source. A small-capacity (below 10kW) straight-bladed vertical axis wind turbine can compete with conventional sources in niche markets. It converts wind energy to useful energy vectors or carriers, such as heat, e

A constant-current electro-osmotic dewatering (EOD) of various solid–liquid systems is analyzed using the Terzaghi–Voigt combined model by considering the creep deformation of the material. Electro-osmotic dewatering experiments under constant electric current density of bentonite clay, KC-flock, zinc oxide and some of their mixtures are carrie
