Bog bodies‚ also known as bog people‚ are preserved human bodies found in sphagnum bogs in Northern Europe‚ Great Britain and Ireland. Unlike most ancient human remains‚ bog bodies have retained their skin and internal organs due to the unusual conditions of the surrounding area. These conditions include highly acidic water‚ cold temperature‚ and a lack of oxygen‚ combining to preserve but severely tan their skin. Although their skin is preserved‚ their bones are generally not‚ as the acid in

The Grignard Synthesis of Triphenylmethanol Abstract: Grignard synthesis of triphenylmethanol was achieved by use of the Grignard reagent phenyl magesium brominde. The organometallic grignard reagent was synthesized by use of a reflux apparatus recrystallization techniques. Once synthesized it was used in a Grignard reaction that involved nucleophilic addition to a carbonyl in order to make triphenylmethanol. The final product was solidified and recrystallized and spectral data was

As suggested‚ we performed the enzymatic experiments as described in material and methods. It was observed that CgAKR-1 has activity on acetaldehyde‚ corresponding to 59.2 % of the activity with the standard substrate 2-nitrobenzadehyde. Moreover‚ the enzyme had no activity against acetone (Propanone); the result was included in Table 1. According to Santoro et al. [76]‚ it was not detected acetaldehyde in hemicellulosic hydrolysate‚ which was produced at the same conditions described in the present

Isolation & Identification of the Major Constituent of Clove Oil with Steam Distillation The purpose of this laboratory experiment was to isolate and characterize clove oil in order to understand how to isolate organic compounds with high boiling points‚ how to perform and interpret qualitative tests for organic compound functionality‚ and to continue to learn how to perform and interpret IR spectrometry. Steam distillation was used in order to prevent the organic compound from decomposing

How does pollution in large cities affect human health? It is generally known that‚ with the development of industry‚ the environment becomes deterioration. The fast speed of the development leaves us serious pollution problems‚ which may affect human health. It is more prominent in urban areas as a result of excessive industrialization. In 1930‚ 6000 people became ill and 60 died by breathing toxic gases emitted from factories in the Meuse Valley in Belgium (Seitz‚ 2008). In addition‚ approximately

Results and discussion Pyrolysis is one of the thermochemical technologies for converting biomass into energy and chemical products consisting of liquid bio-oil‚ solid biochar‚ and pyrolytic gas. It is derived from the complex conversion network of the three main components in biomass: cellulose‚ hemicellullose and lignin (Kan et al.‚ 2016). Degradation Characteristics of A. magnium wood The purpose of this research is to determine the main points of A. magnium thermal degradation‚ based on DTG

According to the Columbia Encyclopedia “smoking is considered a health hazard because tobacco smoke contains nicotine‚ a poisonous alkaloid‚ and other harmful substances such as carbon monoxide‚ acroleing‚ ammonia‚ prussic acid‚ and a number of aldehydes and tars.
