The literature value for the melting point range for Trans-9-(2-phenylethenyl)anthracene is 130-133 oC. The obtained range was lower than that at 120.3 to 123.8 oC. Because it is lower than the known value‚ this means the obtain product is not completely pure. Impurities in the compound can result in a decrease in the compounds melting point‚ which is observed here. The impurities could be 1-propanol due to an insufficient drying. If the experiment was performed again‚ the product would need to be

density of states and detonation properties of trans and cis configurations of azocubane. All properties have been obtained using the B3LYP functional and 6-31G(d‚p) basis set. Also‚ IR‚ UV-Vis‚ CD and NMR spectra of the structures were simulated. The volumes of the structures computed to get the densities of the molecules. All calculations carried out in gas phase at temperature 293.15 k and pressure 1 atm. The simulation results revealed that the trans configuration of azocubane exhibits more stability

There are trans fats everywhere in the foods we eat everyday. If something we eat doesn’t have a trans fat then it probably has a saturated fat. Baked goods‚ cookies‚ cakes‚ and frozen foods have high levels of trans fats. Things that are incorporated into almost everyone’s diets. We can’t completely eliminate trans fats AND saturated fats without taking away many foods that everyone enjoys. Restaurants would more than likely lose more business than they already are in this recession. Yes‚ it may

Myeloid tissue Is the bone marrow Why we discuss myeloid tissue/bone marrow? – because we want to study the development of blood cells. We called it HEMOPOEISIS/HEMATOPEISIS HEMOPEISIS/HEMATOPOEISIS –Blood cell formation (occurs in the bone group) Why study this? Because: there is a continuous replacement of cells they have short life span when they are in the peripheral circulation so‚ we have to study how these cells mature and differentiate Phases of hematopoeisis MESOBLASTIC PHASE
