3.1 MATERIALS Kinnow: Kinnow used in this study were procured from local market of Hisar. Identical cultivar, color and source were selected in an attempt to minimize variability in carotenoids and ascorbic acid contents which were associated with variety, color and growing conditions. Procured kinnow samples were fresh, mature, fully ripened and were free from any spot and blemishes. Chemicals: All chemicals used during study were of analytical grade (AR) and were supplied by Qualigens…

mixture was poured into 60 mL boiling water containing 2N potassium hydroxide. The solid product was separated and acidified with dilute sulphuric acid, then washed with distilled water and dried at 45 for 12 h. Recrystallization from benzene and the methanol – water system gave light yellow crystals. The synthesis of the HPMCP is shown in Fig. 1. Yield…

A Poison as Sweet as Sugar Introduction/Thesis There are many different alternatives to sugar that a person can use in their foods. Some of the most common are Aspartame (known as Nutrasweet or Equal), Sucralose (Splenda), Saccharin (Sweet Twin), and Xylitol or Sorbitol. Most artificial sweeteners are not a healthy alternative, and Aspartame is no different. This artificial sweetener, accidentally found by a researcher, known as James M. Schlatter, who was working on a treatment for stomach…

title>INTRODUCTION Optical constants (complex refractive index n, complex dielectric function ϵ, and reflection and absorption coefficients R and α) of materials are of great importance for optical metrology in the semiconductor industry.1,2 A high-performance complementary-metal-oxide-semiconductor process flow with 11 layers of metal requires about 75 photolayers and may contain up to 100 thickness measurements, most of them performed using spectroscopic ellipsometry.3 This technique has…

the APS solution was added to the aniline solution in drop wise manner with slow rate (15 min) with simple discontinuous manual stirring. The solution was kept at for 24 h. The prepared polymer was collected and washed by 0.2M of HCl, Ethanol, and methanol then filtered by centrifugation for 15 min at 5000 r.p.m. The polymer was dried into an oven for 6 hrs at temperature of 60…

and Food and Drug Administration(FDA) data sheets. The data sheets reveal a list of ingredients within select vaccines, and confirms that formaldehyde is a prevalent additive. Formaldehyde is a colorless pungent gas in solution made by oxidizing methanol. In 2011, the CDC and the american cancer association(ACA) stated that formaldehyde is a carcinogen. Kacie Weeks Mr. Beltran HUM II5 November 1, 2016 Decline in disease is due to improved health and living conditions. In the 19th century the…

indica (seed) respectively in mustard oil in field conditions. The petroleum ether extract of Vicoa indica, Buddleja asiatica, Chenopodium ambrosoids, Chlerodendrum inerme and methanol extract of Solanum erinthum gave 3 hours protection against mosquitoes at 9% concentration [14]. Young-Cheol et al. [15] reported that the methanol extract of Cinnnamomum cassia bark, Nardostachys chinensis rhizome, Paeonia suffruticosa root bark and steam distillate of Cinamomum camphora gave 91, 81, 80 and 94%…

Hydraulic fracturing is a process which releases natural gas from shale and brings it to the worlds surface. It requires injecting more than a million gallons of chemicals such as lead, uranium, methanol, and mercury. Fracking also needs sand and water. The amount of water that is used is one to eight million gallons per job. It takes 400 tanker trucks to carry water too and from the sites. The chemicals, sand, and water are then put down a horizontally drilled well at a high pressure. The…

in mind as state legislators establish criminal, and occupation safety and health laws against smoking in public. Cigarettes contain a multitude of known carcinogens and toxic substances, such as acetone, ammonia, carbon monoxide, lead, arsenic, methanol, butane, and formaldehyde. The most prevalent substance in tobacco cigarettes is the addictive substance, nicotine (American Lung Association). The myriad of short term and long term health consequences of cigarette smoke is well known. Smoking…

For today’s paper I will discuss the following points as the core for my paper: • The $80 billion bailout of GM, GMAC, Chrysler, and Ford. • Global Warming and the effect of emissions • Alternative fuels and new design competition First topic is the $80 billion bailout of the “Big 3” which are GM, Chrysler, and Ford. This bailout started in 2009 after GM and Chrysler asked for funds to avoid falling into bankruptcy. These companies were the leaders in car sales in the United States and go back…
