EXECUTIVE SUMMARY Natural skin care is the care of the skin by applying naturally-adopted ingredients mixed with naturally occurring carrier. Agents, preservatives, surface-active agents, humectant and emulsifiers. The classic interpretation of natural skin care is established on using botanically procured ingredients currently existing in nature or is cultivated by nature, without the use of fabricated chemicals, and assembled in such a way to preserve the integrity of the ingredients. Skin…

Combustion, a chemical reaction between substances, usually including oxygen and usually accompanied by the generation of heat and light in the form of flame. The hydrocarbons become harder to ignite as the molecules get bigger. Combustion of alkanes with bigger molecule will produce more soot as the percentage of carbon of the molecule is higher. The amount of soot produced depends on the percentage of carbon in a hydrocarbon molecule. Hexane and cyclohexene produced very small of light soot…

Chotukool is a 45-liter plastic holder that can cool nourishment to around 8 to 10 degrees on a 12-volt battery. Forsaking the compressor innovation utilized as a part of local ice chests, it utilizes a thermoelectric or robust state cooling framework. It doesn't have a front opening entryway however opens from the top to guarantee that the greatest measure of cool air stays in the compartment when opened. The thought of Chotukool was conceptualized focused around the standards of Disruptive…

Magnesium Alloy: Microstructure Characteristics: Fig (8) : Shows the microstructure of Magnesium alloy. Picture source: http://www.omicsonline.org/JMSTimages/2155-9589-2-114-g001.html Magnesium alloys have a hexagonal lattice structure. They are the lightest of all structural metals. Magnesium alloys possess a low galling tendency as a bearing surface in conjunction with shaft hardness above 400…

Question 1 When first looking at the title and subtitle for Ray Bradbury's book, Fahrenheit 451, as well as the illustration that is depicted on the cover of my hardcopy, I thought that this book would feature higher-than-normal temperatures, fires, and burning as story elements. The title reads like a fancy way of saying four-hundred-fifty-one degrees Fahrenheit, and when combined with the fiery subtitle, which details more specifically that this is “the degree at which paper catches fire and…

B.Result and discussion Percentage air voids On the replacement of cupola slag we obtained the result that, on the percentages of 10, 20, 30 and 40 we have the Va values of 4.8, 4, 4.8 and 3.2 % which satisfies the morsth requirement of 3-5% and further we observed that the gradual decrease in the Va values up to 100%. So that for Va the replacement of cupola slag up to 40 % will satisfies the morsth requirement. Percentage of voids in mineral aggregate On the replacement of cupola slag we…

Introduction 1.1 Polyurethane polyurethanes were first developed by Otto Bayer and coworkers in 1937. Shortly thereafter, Schollenberger and coworkers used formula modification to prepare elastomeric polyurethane products from Bayer's products that were like nylon or other engineering plastics in physical characteristics. PUs are widely used in coatings, flexible and rigid foams, elastomers, and composites. Reasons for the use of polyurethane coatings include: high performance characteristics…

ABSTRACT The reactivity of acid base cements forming hydroxyapatite (HA) such as, β-tricalcium phosphate (β-TCP) and dicalcium phosphate dehydrate (DCPD). Amorphous calcium phosphates, prepared by precipitation from supersaturated solutions, can also react to form apatitic cements since they are thermodynamic unstable with respect to HA and have a setting reaction more independent of particle size. Calcium phosphate cement containing an antibiotic can be used for filling bone defects and to…

ABSTRACT Dex-Ibuprofen–polyethylene glycol (PEG) conjugates (PEG-dex-Ibu) were organized and their prospective as a prolonged release method was investigated. PEG-Dex-Ibuprofen conjugates were synthesized as of Ibuprofen and PEG with 4000 Da molecular weights by esterification in the incidence of DCC and DMAP. The PEG-dex-Ibu conjugates were characterized by FT-IR, 1H NMR, and DSC analysis. The solubility revise in aqueous system showed an improvement within the solubility of conjugates. The…
