Chemistry deals with the conversion of substances into new substances through the formation and breakage of chemical bond. This conversion may happen at different speed. Some reaction happens instantaneously whereas some takes millions of years to happen. Reaction rates are of great importance. The feasibility of a chemical reaction particularly a commercial chemical process often depends on the reaction rate if the process is too slow it may not be suitable for commercial exploitation. It also relates, for example, what...

Abstract TheEarthis rich in oil and natural gas also have huge deposits of salt-below the surface. Recognizing if a subsurface objective is salt or not consequently and precisely is of indispensable significance to oil penetrating. Be that as it may, sadly, acquiring the exact situation of enormous salt stores is troublesome. Proficient seismic imaging despite everything requires the understanding of salt bodies by specialists. This prompts exceptionally abstract, profoundly factor renderings. All the more alarmingly, it prompts conceivably risky circumstances...

Throughout time, our country has had many pollutants in our soil throughout time. Some are natural, but as we look closer to the industrial revolution, many are man-made. As this began, we realized many plants were not surviving near rivers and streams that were highly polluted, they also did not survive well near mines, because of the high amount of metals, or what other things were being mined (Denchak, 2019). Due to all of these pollutants, there is a lot...

The application of copper in the soil medium at a level of up to 4 times higher than the MPC contributed to an increase in the activity of cellulose-destroying microorganisms to 16 relative per cent. A further increase in the level of copper pollution to 10 times higher than the MPC of Cu was accompanied by a significant suppression of the activity of soil biota and its activity with respect to the control significantly decreased. A certain amount of copper...

Abstract Atopic dermatitis (AD) is a multifactorial, chronic inflammatory skin disorder resulting from disruption of the epithelial barrier and inflammation. A wide range of treatments are currently available for AD, aimed to restore impaired skin barrier and control inflammation. In order to avoid systemic therapy, the soak and smear technique, the wet-wrap treatment (WWT) with physiologic lipid-based barrier repair therapy and proactive use of topical corticosteroids, can represent an alternative and excellent option, with encouraging results. We report this strategy...

In 1975, the first PC was made and since then, PC’s have become much more powerful. The first PC was created by IBM. Also, that was when the first motherboard was seen. Copper is used in motherboards as copper is not very reactive and can hold heat well. Copper only reacts when it is heated and is in contact with air/oxygen, which is why it is a preferred choice by manufacturers. Copper needs contact with air/oxygen so it can react...

Introduction The browning of an apple or other foods like potatoes and bananas are something that we have all seen in our everyday life. This phenomenon is caused by the interaction of enzymes, that are naturally found in plants, with oxygen. These enzymes oxidize to create the brown colour that we are familiar with. Enzymes are natural catalysts that help to speed up certain chemical reactions within plants and animals (DiGiuseppe, Frazer, LeDrew, Vavitsas, &White-McMahon, 2012, p. 50). Enzymes bind...

Diffusion of Innovation (DOI) Theory, developed by E.M. Rogers in 1962, is one of the oldest social science theories. It originated in communication to explain how, over time, an idea or product gains momentum and diffuses (or spreads) through a specific population or social system. The end result of this diffusion is that people, as part of a social system, adopt a new idea, behavior, or product. Adoption means that a person does something differently than what they had previously...
