cause differences in the hazards posed by volcanoes around the world (40 marks) Your main factors can be put into two simple categories. Human and physical. From there you can then further explore the factors. In my essay I will mainly focus on viscosity‚ location‚ settlement and perception and explore how the physical and human factors intertwine with each other through one simple idea that physical factors dictate the hazard while human factors exacerbate the hazard. From here we must define a

determine the best soft-boiled egg. In a soft-boiled egg‚ the egg yolk will be a thick liquid. Viscous (Viscosity) Viscous is having the property of viscosity (Dictionary-viscous). Viscous is a thick and sticky substance that is between liquid and solid. In egg‚ when an egg is soft-boiled‚ the yolk is a thick liquid. The yolk has the property of viscosity. In the question‚ consistency also means viscosity. Egg White There are four parts in an egg white. The innermost layer of the thick white is called

1) Define Viscosity. It is a measure of fluidity of the system. Many fluids undergo continuous deformation with the application of shearing stress. 2) Define Newtonian fluids If the force flow relation is linear then the fluid is Newtonian . 3) Define Non Newtonian fluids If the force flow relation is non linear then the fluid is Newtonian . 4) Define Kinematic Viscosity. Ratio of absolute viscosity to the density of the fluid. V= µ cm2 /ς sec 5) Define Specific Viscosity. Ratio of absolute

proportional to resistance. Recall that resistance is a measure of the degree to which the blood vessel hinders or resists the flow of blood. The main factors governing resistance are 1) blood vessel radius‚ 2) blood vessel length‚ and 3) blood viscosity. Radius. The smaller the blood vessel radius‚ the greater the resistance‚ due to

high-performance thin-layer chromatography method has been developed for the quantitative estimation of gatifloxacin and ornidazole in its combined dosage forms. Gatifloxacin and ornidazole were chromatographed on silica Gel 60 F254 TLC plate using n-butanol: methanol: ammonia (6 M) (8:1:1.5 v/v) as the mobile phase and scanned at 302 nm using a Camag TLC Scanner 3. The linearity of gatifloxacin and ornidazole were in the range of 100-500 ng/spot and 250-1250 ng/spot‚ respectively. The limit of detection was

2a: Infrared Spectroscopy and Analgesic Drug Identification Abstract: To be able to understand how organic soluble compounds could be isolated from non-organic components‚ a chromatographic separation process was used. The objective of the analgesic drug identification is to isolate the organic compounds/ active ingredients in an unknown drug. The identity of the drug was determined through melting point‚ percent recover‚ and Rf values. The comparable data for acetaminophen from the manufacturer
