Water wheel

Pharmacopoeia fall into the poorly water-soluble or water-insoluble categories.It was reported a couple of decades ago that more than 41% of the failures in new drug development is attributed to poor biopharmaceutical properties, including water insolubility.Water insolubility can postpone or totally halt new drug developmentand can prevent muchessential reformulation of currently marketed…

Sun reflects very strong UV light. UV light can be dangerous for humans in many ways. It can be harmful to our skin and eyes. We need to protect our eyes and skin from strong direct UV light of sun. The problem that I would like to discuss is about the effects of the UV light on skin. Sunlight can cause skin cancer. Skin cancer is one of the most common cancers in the world. The most dangerous skin cancer type is called melanoma. It is a cancer of pigment(color)-producing skin cells. It is…

appropriate program specified in the Control Unit to determine the time of boiling (15 minutes), rinsing (30 minutes), recovery (10 minutes) and pre-drying (5 minutes). Open the tap water to allow the reflux process occurred in a condenser at Extraction Unit. With the cooling process by water at about 15 ̊C, the water flow should be adjusted to the rate of 2 L / min to prevent boiling of solvents from the condenser. Preparation of sample is done with paved filter paper, weighing accurately 2.0 g…

had to worry about was her best friend Alana Blanchard stealing her waves. No school and no stress was the vibe on that Halloween morning. Upon arriving at the beach, Bethany and her good family friends the Blanchard’s were anxious to get in the water. They padded about a mile out to where some decent sized…

Abstract Snow avalanches pose a significant hazard to human populations and infrastructure in mountainous regions. Snow avalanches are the abruptly down slope movement of snow, ice, and associated debris such as rocks, and earth material. The forces generated by large avalanches can damage most man-made structures. Avalanche impacts in India, includes fatilities, is summarize for public and residential area like ski areas, roads, and resource industries. Avalanche hazard methods, in which…

B Sridhar et al (2012) studied Purification and Characterization of Biosurfactants. The emulsifications of biosurfactants were checked in various oils such as olive, coconut, sunflower and rice bran oils, the emulsification activity of biosurfactants. Pseudomonas aeruginosa had higher emulsification activity than Saccharomyces cerevisiae. While checking the sugar and lipid content in biosurfactants by phenol sulphuric acid method and vanillin reagent method, found high in Pseudomonas aeruginosa…

in liquid form, it also may exists in vapor form in air. In order to produce a colourless and odourless chemical, propylene glycol (C3H8O2, PG) involve in the reaction of propylene oxide and water. This involve the process of the hydrolysis of propylene oxide (C3H6O, PO) with the presence of excess water and a small concentration of catalyst. The catalyst that plays the role in this reaction is the sulphuric acid. The reaction occurs in the reactor at the reasonable rate which near the…

Abstract:The second order rotatory theory of hydrodynamic lubrication was founded on the expression obtained by retaining the terms containing first and second powers of rotation number in the extended generalized Reynolds equation. In the present paper, there are some new excellent fundamental solutions with the help of geometrical figures, expressions, calculated tables and graphs for the porous bearings in the second order rotatory theory of hydrodynamic lubrication. The analysis of equations…

Langmuir isotherm The Langmuir adsorption model is established on the following hypotheses: (1) uniformly energetic adsorption sites, (2) monolayer coverage, and (3) no lateral interaction between adsorbed molecules [26]. A mathematical expression of the Langmuir isotherm is given by the following equation: Where qe (mg/g) is the amount of dye adsorbed on the solid adsorbent at equilibrium, qm (mg/g) is the maximum adsorption capacity, KL (L/mg) is the Langmuir equilibrium…

(about 12cc) was required for the velocity measurement. The temperature of this liquid within the cell could be controlled at any desired value in the range of the room temperature to the boiling point of water, by circulating water at a constant temperature, in the jacket surrounding the cell. The water at a constant temperature was obtained from the separate assembly consisting of the thermostat and small electric…
