Thin films of the recently discovered magnesium diboride (MgB2) intermetallic superconducting compound have been grown using a magnetron sputtering deposition technique followed by in-situ annealing at 830°C. High quality films were obtained on both sapphire and MgO substrates. The best films showed maximum Tc = 35 K (onset), a transition width of 0.5 K, a residual resisitivity ratio up to 1.6,...

What may cause a heart attack build up gradually. Being a couch-potato, boredom eating without exercising are very bad habits that may possibly begin in when we are children. An increasing number of medical doctors are starting to find out victims of heart attacks in their 20's and 30's compared to sufferers mostly in their 50's and 60's. Being in shape and at the ideal weight does not make you...

Background: Recent studies have indicated that working memory is not a unitary resource and that different types of working memory are used for different types of linguistic processing: syntactic, semantic, and phonological. Phonological working memory was found to support the comprehension of sentences that require re-access to the word-form of a word that appeared earlier in the sentence. Aim...

This article is a critical review of some of the methods that have been used for the sampling, analysis, and monitoring of vapor-phase toluene diisocyanate (TDI). Only some of the methods that have received relatively widespread application have been addressed in this article. This review includes a "tutorial style" discussion of basic definitions and basic principles and procedures of quality ...
