INTRODUCTION Environmental issues are attributed to natural or human activities‚ which lead to deterioration of environmental quality or ecological system disorders‚ and adversely affect industrial production and humans’ daily life. Environmental issues may also result in detrimental effects on human health. There are a variety of environmental issues‚ which can be divided into two categories. One is the environmental problems caused by natural evolution and disasters‚ also called the first environmental

INTRODUCTION: We are aware to the luxury of fashion affects our daily lifestyle. That’s why we came up to an idea of making organic resources more useful by inventing a new fragrance that will assure you a new unique scent. Our main of resource is the organic pee urine which can be content on making new tone of perfume together with its essential and fragrance oils and experience some exotic and unusual aromas from other original and unique sources. We’ll prove to you that Science can create a mystery

I. INTRODUCTION Earthworms are segmented invertebrates that inhabit soils and organic wastes. They are hermaphrodites and usually reproduce by mating‚ each partner fertilizing the other. After mating they retract their bodies through the “saddle” or clitellum and pass it over their heads. Each cocoon contains one or more eggs that can survive adverse conditions‚ hatching when environmental conditions are favorable. Some species are able to produce viable cocoons parthenogenetically without

CONCEPTS IN ORGANIC CHEMISTRY • Inductive Effect : Inductive effect is defined as permanent displacement of shared electron pair in a carbon chain towards more electronegative atom or group. Types of Inductive effect : 1.Negative Inductive Effect : (—I effect‚ Electron withdrawing effect) when an electronegative atom or group (more electro negative than hydrogen)is attached to the terminal of the carbon chain in a compound‚ the electrons are displaced in the direction of the attached
