A chemical universe consists of a set X of chemical compounds and a set of reactions between them. Each reaction transforms a finite (small) set of educts in a small set of products. Reactions thus form directed hyperedges on X. Since X can be infinite, it is of interest to consider X not only for a combinatorial point of view but also as a topological construct. Here we argue that generalized ...
Replacement by aluminum for the closure panels is one of the common methods for lightening car body. However the application used to be limited into shallow drawing parts like hood because of its low stamping formability. As a solution to cover the low stamping formability of aluminum, Blow forming technology of aluminum which is one of the superplastic forming technologies has been researched ...
All views expressed in this paper are those of the authors and do not necessarily reflect the views or policies of the U.S. We apply the empirical framework of the displaced worker literature to the study of outcomes for displacing employers. Long-term patterns of employment, wages, and closure probabilities before and after mass layoffs vary by the complexity, age, and industry of employers, r...
On 29 April 2009, an imported case of pandemic (H1N1) 2009 virus infection was detected in a London school. As further cases, pupils and staff members were identified, school closure and mass prophylaxis were implemented. An observational descriptive study was conducted to provide an insight into the clinical presentation and transmission dynamics in this setting. Between 15 April and 15 May 20...
Closure study between chemical composition and hygroscopic growth of aerosol particles during TORCH2
Measurements of aerosol properties were made in aged polluted and clean background air masses encountered at the North Norfolk (UK) coastline as part of the TORCH2 field campaign in May 2004. Hygroscopic growth factors (GF) at 90% relative humidity (RH) for D0=27–217 nm particles and size-resolved chemical composition were simultaneously measured using a Hygroscopicity Tandem Differential Mobil...
the heat and mass transfer analysis for mhd casson fluid boundary layer flow over a permeable stretching sheet through a porous medium is carried out. the effect of non-uniform heat generation/absorption and chemical reaction are considered in heat and mass transport equations correspondingly. the heat transfer analysis has been carried out for two different heating processes namely; the prescr...
