decrease in the viscosity of the reaction medium at higher temperatures‚ etc. Most often‚ enzymatic hydrolysis is carried out with the enzyme α-amylase from different sources and less often β-amylase is employed. The bacterial α-amylase enzymes attack the polysaccharide molecules in the inner part of the chain. They act on the amylose of starch so that they destroy the spiral of the polysaccharide chain and thus the characteristic blue color with iodine disappears. The viscosity of the starch solutions

white to pale yellow colored solution. They have pH in the range of 7.02 – 7.30 (Table 5.2). Viscosity of the formulation was determined using Brookfeild viscometer and the viscosity of the formulation increased with an increase in sodium alginate and pectin concentration (Table 5.3). This phenomenon is a consequence of increasing chain interaction with an increase in polymer concentration. The change in viscosity is proportional to the change in concentration and polymer ratio. The buoyancy lag time

able to sustain a high level of performance throughout their event/race. The risks of blood doping are that: blood viscosity is increased leading to a lower heart rate and clotting causing heart failures and strokes; due to transfusion practises‚ HIV and other diseases could also be a risk; also‚ dehydration causes a decrease in plasma volume which consequently increases blood viscosity leading to the previously mentioned problems. The final risk/drawback is that blood doping is banned. This means

How Surface Area Affects the Motion of a Falling Object Introduction During this investigation‚ varying surface areas of objects will be explored in a manner observing the motion as they fall. Most predominantly‚ this motion encircles speed. Speed is calculated from the formula below‚ and hence is directly proportionate to time taken when the distance travelled remains a constant. Speed = Distance/Time Surface area is likely to affect the time taken for an object to complete a descent‚ and

RESULTS AND DISCUSSION: Ultraviolet spectroscopy of Verapamil hydrochloride at λmax of 278 nm in pH 1.2 buffer was found to be linear in range of 20 – 80 µg/ ml. The method was validated and found to be precise‚ specific and accurate. The tablets of Verapamil hydrochloride were prepared by press coating technique showing sustained release for 24 h for once daily dosing with a lag phase of 4 - 6 h. The optimum ratios and type of polymers and other excipients were chosen to produce gastroretentive

Analysis and Forecast to 2020” report at http://www.persistencemarketresearch.com/market-research/automotive-gear-oil-market.asp Automotive gear oil generally has high viscosity level in comparison to transmission fluid and automotive engine oil. This is necessary for better performance and protection of gears. The high viscosity level provides better transmission of lubricant throughout the gear trains. Devices requiring heavy oil do not have to use extra force to transfer the oil‚ since only
