Clear Idea

The present study deals with the term of history linguistically and terminologically from Arab and Western Europe. This term is radically intertwined between East and West, specifically the Greek language. The present study covers the views of ancient historians and modernists as much as possible to have a clear idea of the topic. Section two is devoted to answering the important question of whether history is a science or an art by presenting most of the opinions that have been put forward in this regard, whether by Western or Arab historians to ultimately reach a comprehensive, complete, and final answer, at least until present time. Section three is related to the science of history for Muslims and its impact on the science of history in the West. Rosenthal’s opinion, which reflects the views of the majority of orientalists will be explained to respond to it showing evidence of the extent of this influence and how it was the initiation step and the most influential catalyst for the intellectual renaissance of Europe in general and in historical writing in particular.

Monomeric styrenes are demonstrated as excellent embedding media for electron microscopy. Monomeric styrene has extremely low viscosity and low surface tension (less than 1) affording extremely rapid penetration into the specimen. Spurr's Medium based on ERL-4206 (J.Ultra. Research 26, 31-43, 1969) is viscous, requiring gradual infiltration with increasing concentrations. Styrenes are soluble in alcohol and acetone thus fitting well into the usual dehydration procedures. Infiltration with styrene may be done directly following complete dehydration without dilution.Monomeric styrenes are usually inhibited from polymerization by a catechol, in this case, tertiary butyl catechol. Styrene polymerization is activated by Methyl Ethyl Ketone peroxide, a liquid, and probably acts by overcoming the inhibition of the catechol, acting as a source of free radical initiation.Polymerization is carried out either by a temperature of 60°C. or under ultraviolet light with wave lengths of 3400-4000 Engstroms; polymerization stops on removal from the ultraviolet light or heat and is therefore controlled by the length of exposure.
