The primary goal of the BRAVO study was to apportion the major aerosol species to their emission sources, with the secondary goals of understanding the physio/chemical/optical properties of aerosols at Big Bend and surrounding areas. To achieve the secondary goals, a number of detailed measurements of the particulate chemical composition, size distribution, hygroscopicity, and the particles’ op...

We consider two-flavor asymmetric QCD combined with a low-energy effective model inspired by chiral perturbation theory and lattice data to investigate the effects of masses, isospin and baryon number on the pressure and the deconfinement phase transition. Remarkable agreement with lattice results is found for the critical temperature behavior. Further analyses of the cold, dense case and the i...

Much of the power of chemical ionization mass spectrometry stems from the finding that the characteristics of the Cl mass spectrum produced is dependent on both the nature of the reagent gas and the type of ion-molecule reaction used to ionize the sample. Different structural information can be obtained with different reagent gases. As a consequence, it is possible to control the type and quant...

Mass action kinetics are used throughout the chemical and chemical engineering literature to describe the dynamics of systems of chemical reaction laws. They are also a special form of compartmental systems that involve mass balance relations [l]. Aside from their obvious importance in chemical engineering applications, mass action kinetics have numerous analytical properties that are of inhere...

the possibility of chemical modification of peptides and proteins under the condition of proteolytic digestions and fabms analysis was investigated. the results ;indicate that among the amino acid constituents of peptides and proteins: serinefcysteine, and cystine are the most sensitive residues which undergo chemical modificadons under the exprimenta1 conditions. the chemical modification of t...

purpose: to evaluate all cases of drug induced angle closure glaucoma cases who presented to feiz hospital, isfahan during 2008-2010. case report: in this retrospective case series, we present 7 cases of drug induced angle closure glaucoma after administration of topiramate. all patients were female. the average age of patients was 33.28 years old (ranging from 19 to 44). with sufficient cornea...

Cyanoacrylate (CA) glues are commonly used in medical and household repairs. Their chemical compositions have been refined over half a century, making some more suitable than others for creative applications. In remote settings where advanced medical care is not accessible, readily available CAs of differing chemical composition may possess an important therapeutic function. Within this paper w...

This paper reports a kinetic study on modified CVD process in porous ceramic substrates by both theoretical analysis and experimental approach. The theoretical analysis indicates that with a heterogeneous chemical reaction the decrease of the pore size is proportional to the deposition time and the pore closure time is proportional to the original pore size. While for a homogeneous reaction the...
