This project was undertaken to study the biodegradability of PLA-KF biocomposite in different conditions; soil burial and immersion in water. The samples were buried in soil for 40 days to investigate the degradability of biocomposites. As for water absorption tests, the samples were immersed in three different types of water which were river water (pH 6), tap water (pH 7) and sea water (pH 7.5...

The purpose of this study is to summarize water, carbohydrate (CHO), and electrolyte absorption from carbohydrate-electrolyte (CHO-E) solutions based on all of the triple-lumen-perfusion studies in humans since the early 1960s. The current statistical analysis included 30 reports from which were obtained information on water absorption, CHO absorption, total solute absorption, CHO concentration...

background: this study was carried out to determination of heavy metals (cd, cr, cu, fe, pb, ni and zn) concentration in upstream and downstream of the entry of the wastewater (untreated urban, traditional slaughterhouse waste, leachate from solid wastes has accumulated in river and  run off waters flowing across the city ) to the tembi river. methods: samples were collected for 1 year, before ...

objectives: the aim of this study was to assess and compare the water sorption and flexural strength of thermoplastic and conventional acrylic resins. materials and methods: water sorption and flexural strength were compared between a thermoplastic modified polymethyl methacrylate (pmma) denture base resin (group a) and a heat-polymerized pmma acrylic resin (group b) as the control group (n=10)...

T he performance of a new type of gas absorber was investigated. Laboratory absorption experiments on different absorption systems such as ethyl–thiol, acetone–water, ethanol–water, methylene chloride–festo oil and H2S–NaOH were carried out under reduced air pressure. The absorption rate was investigated as a function of geometrical parameters and construction materials. The possibility of inst...

A desired ointment bases for better treatment of bedsores was developed to improve the release rate of minocycline hydrochloride (MH) and the water absorption capacity using various types of hydrophobic to hydrophilic ointment base. The influence of purified lanolin (PL) on the release behavior of MH from hydrophilic ointment (HO) base was primarily focused on. It was found that the release rat...

TThis study investigated the water absorption of chitosan, collagen, and chitosan/collagen blend membranes exposed to gamma-ray irradiation. These membranes were produced via the solvent evaporation method. All membranes then underwent irradiation at 15 or 25 kGy gamma-ray doses, while membranes without irradiation were used as controls. After immersing the membranes in distilled water for up t...

six different composite packaging materials were tested with the trades’ practice of polythene bags in storing smoked catfish for a period of six months. the thickness of the packaging materials ranges from 0.23 to 046 mm with water and oil absorption rates of the packaging materials varies from 0.23 to 10.00 and 0.28 to 10.857 glcm2/mm respectively. the impact resistance weight also varies fro...

Mercury has long been recognised as a neurotoxin element for many decades and with its compounds being extremely toxic, is ranked third in the ‘priority list of hazardous substance’ by the United States comprehensive environmental response, compensation, and liability act. In different samples, mercury can exist as either its inorganic or organic forms and this paper will review the methods for...

STARZECKI, B., AND D. F. J. HALMAGYI. Absorption of inhaled water in experimental Fulmonary edema and embolism. Am. J. Physiol. 201(s) : 762-764. 1961. -The effect of pulmonary edema and pulmonary embolism on the rate of absorption of standard amounts of inhaled fluids was investigated in rats. Relative lung weight ( = lung weight in per cent of body wt.) was used as an index of the fluid conte...
