1. ABSTRACT In all precipitation reactions, the ions of one substance are exchanged with the ions of another substance when their aqueous solutions are mixed. At least one of the products formed is insoluble in water. Two ionic compounds exchange ions. Reaction will not occur unless one of the products either precipitates, or is water. Dissociation, Ionic compounds – Metal + nonmetal (Type I & II) – Metal + polyatomic anion – Polyatomic cation + anion , Dissociation: when ionic compounds dissolve
I. Once, there was a time where the Earth was healthy. There was an abundance of clean air, many plants and animals thrived, and the temperature was cooler. The Industrial Revolution then came, bringing along with it smoke, greenhouse gases, and a significant increase in the Earth’s temperature. This change in temperature is known as global warming, and it causes an particularly serious problem called climate change. Climate change is mainly caused by the high levels of greenhouse gases in
Mercury as a pollutant in aquatic ecosystems Mercury is a highly toxic pollutant that rapidly spreads all over the world from its natural and anthropogenic sources. Although atmospheric mercury concentrations have been decreased by 20 to 38% since 1996 (Slemr et al. 2011), mercury pollution is still a severe threat to aquatic ecosystems. Recent causes of mercury pollution in aquatic ecosystems include oil and coal combustion, agricultural drain water and atmospheric deposition from electric power
fruit, Mangosteen of G. mangostana Source: http://www.positivehealth.com/article/nutraceuticals/the-mangosteen-fruit-garcinia-mangostana-science-and-ongoing-research The hulls of the mangosteen fruit is the one that have chemicals that provide anti-inflammatory effects. Its constituents are α-mangostins and γ-mangostins. It has proven in a research study that it helps in inflammation [8]. Different Methods of Screening In-vitro screening of anti-inflammatory effects of Harpagophytum

methane and hydrogen) (Nigam & Singh, 2011). The secondary biofuels can be segregated into first, second and third-generation biofuels based on the substrate availability, technology maturity and GHG gas emission balance. (Bharathidasan et al. 2011). Research has provided more progressive and productive conversion technologies for the extraction of biofuels in solid, liquid and gaseous forms from ingredients such as wood crops and waste material. (Nigam & Singh,
The human eye can be classified into two segments: anterior and posterior segments. The cornea, conjunctiva, iris, ciliary body, aqueous humor and lens are includes in the anterior segment and sclera, choroid, retina, vitreous humor are includes in the posterior segment. The outermost transparent membrane of the eye is cornea such are the corneal epithelium, bowman's membrane, stroma, descemet's membrane, and endothelium. The anterior segment is a fluid of the eye which contains the source of nutrition
Statistical approaches in the pharmaceutical formulations have the advantages. Central composite design (CCD) was used for this purpose. In the study the computerized software Design expert 9 was used for the implementation of CCD. The target of this research is to develop the controlled release tablets of epalrestat, five formulations were chosen by using central composite design (CCD) in response surface methodology (RSM). The results were not according to the plan for which the experiment was planned
Titanium (Ti) has been widely used in many fields such as aerospace, automotive, engineering and medical. The main properties of Ti are high strength, low density, and excellent corrosion resistance influence their value. These properties make them very attractive for a variety of applications. Ti alloys provide structural materials in the aeronautics and astronautics industries because of their high specific strength but they are expensive. Stainless steel is a widely used and it is an inexpensive
The demand for starches arises largely from the paper, textile, construction and pharmaceutical industries. Food sector is one of the potential sector which is largely untapped due to legal restriction regarding the use of modified starches which results in low rate growing in food sector. The demand
