In jaggery making furnaces, sugarcane bagasse is used as fuel. Moisture content of bagasse affects its calorific value. So burning of bagasse at suitable level of moisture is essential from the viewpoint of furnace performance. Moisture content can also be used for indirect calculation of fibre content in sugarcane. Normally gravimetric method is used for moisture content determination, which i...
obtain their surface in square centimeters. This simple method provides a means by objective measurements to make evident ehanges in the surfaee of wounds that are not apparent to the naked eye. Figure 1 shows. the observations recorded with this method :in a man of 42 years of age with hemiplegia and a decubital ulcer over the right buttock. The clini cians who had observed this wound daily h...
In an industrial cooling circuit supplied with raw river water, the scaling phenomenon can reduce cooling efficiency and even lead to the shut down of the power plant. During the last twenty years, various methods have been developed in order to estimate the scaling propensity of natural waters, which involve the precipitation of calcium carbonate (CaCO3), the main component of scale. The FCP (...
There is growing interest in the use of compliant materials as an alternative to hard bearing materials such as polyethylene, metal and ceramics in artificial joints. Cushion form bearings based on polycarbonate-urethane (PCU) mimic the natural synovial joint more closely by promoting fluid-film lubrication. In the current study, we used a physiological simulator to evaluate the wear characteri...
The coulometric method presented here is a reliable method for the direct analysis of CO2/air cylinder gas mixtures. It is based on Faraday's laws of electrolysis and therefore no external standardization is required. A series of CO2/air cylinder gas mixtures ranging in concentration from 300 to 375 µmol/mol (ppm) were analyzed and the results compared to those results obtained by non-dispersiv...
Simple methods are described for the analysis of sulphate, sulphite and dithionate mixtures by potentiometric titration with lead perchlorate (and use of a lead ion-selective electrode). The error and precision are both about 2-5% for the sulphate concentration range 3 x 10(-3) -6 x 10(-4)M. The sulphur content in fuels derived from refuse was determined by potentiometric titration after bomb-c...
We have quantified retinal edema in rat by specific gravity measurements in vitro. Specific gravity corresponds to tissue water content, which is increased in retinal edema. The gravimetric analysis of retinal edema corresponds well with light and transmission electron microscopy and radiolabelled albumen studies. Specific gravity measurements are the standard method to measure brain edema and ...
Samples of surimi were prepared in laboratory conditions from Adriatic pilchard (Sardina pilchardus). Water content in surimi was 81.5% before mixing with NaCl and κ-carrageenan, which were added in the range of mass fraction from 0 to 10%. Relative apparent specific enthalpy !, initial freezing point Ti, density ρ, and thermal conductivity k of surimi in the temperature range from -25 C to 10 ...
DURING the course of experimental work with various methods for the determination of total protein in blood-plasma and serum, an endeavour was made to weigh the protein resulting from precipitation with trichloroacetic acid followed by washing with alcohol and ether. The results, compared with the direct gravimetric method of Knipping and Kowitz [1924] as modified by Starlinger and Hartl [1925]...
