Kinetic study on propane ammoxidation to acrylonitrile over V–Sb–O/TiO2(B) was undertaken by a strict mathematical analysis of experimental rate dependencies on reactant pressure in order to obtain expression describing completely the data.
The study aimed to find out the problems connected with feet during work in cold loose housing barns in wintertime. 13 dairy farms and 20 workers were studied. Skin temperatures and subjective responses were collected, and at the end of a work period the subjects filled in a questionnaire about the workday. The foot skin temperatures were measured on dorsal foot and second toe. Most of the workers
Få kontinenters historia är så präglad av myter och fördomar som Afrikas och ännu idag är det vanligt att beskriva dess historia som statisk och afrikanska samhällen som primitiva. 'Afrika - en kontinents ekonomiska och sociala historia' visar istället en dynamisk och variationsrik kontinent. Boken handlar om den ekonomiska och sociala utvecklingen i Afrika söder om Sahara i ett långsiktigt perspe

The proteins of the serpin family are primarily but not exclusively proteinase inhibitors, which share a common, similar structure. It is known that this structure undergoes major conformational changes upon cleavage in the serpin reactive site loop, and that these changes include rearrangements within the hydrophobic core of the molecule. AAT and the free C-terminal peptide dissociated from cleav
The article describes how archaeologists can and have used experiments to answer questions about past behavior.
Popular Abstract in Undetermined Most of the things that we use daily are the product of chemical reactions. Plastics derive from the polymerization of smaller molecules, drugs are synthesised rigorously by pharmaceutical industries, and products for the house and personal care contain a number of different chemicals and fragrances. All these compounds are produced by different branches of the cheWith the emergence of Green Chemistry, biocatalysis is becoming an important approach in many laboratory and industrial processes. Enzymes catalyse chemical reactions with high regio- and stereoselectivity at mild conditions and, most importantly, are able to form products that are not possible to obtain by conventional synthetic chemistry. Monooxygenases are a fascinating group of enzymes which o
Popular Abstract in Swedish Ordet polymer användes första gången av Berzelius år 1830 och kommer ursprungligen från grekiskans polymeres, vilket betyder av flera delar ("poly"=flera och "meros"=del). En polymer är en lång molekyl gjord av flera upprepande enheter. Polymerer finns i naturen (t. ex. DNA och proteiner) men kan också tillverkas genom syntetiska processer. Om polymeren innehåller laddaThe work in this thesis concerns polymer gels, especially their swelling and mechanical properties modelled using a coarse-grained model of polyelectrolytes. The method used to study polymer gels was molecular simulation utilising the simulation package MOLSIM. Particular focus is on the effect of salt, macroions and network topology effects (polydispersity, loose-ends and interpenetrating network
