We study galactic enrichment with rapid neutron capture (r-process) elements in cosmological, magnetohydrodynamical simulations of a Milky Way-mass galaxy. include variety models, based on either star mergers or rare class core-collapse supernova as sole r-process sources. For the first time cosmological simulations, we implement natal kicks on-the-fly to their impact. With kicks, are more like...

We use XMM-Newton data to carry out a detailed study of the Si, Fe and Ni abundances in the cool cores of a representative sample of 26 local clusters. We have performed a careful evaluation of the systematic uncertainties related to the instruments, the plasma codes and the spectral modeling finding that the major source of uncertainty is in the plasma codes. Our Si, Fe, Ni, Si/Fe and Ni/Fe di...

A simple sample pre-treatment method utilizing hollow fibre supported liquid membrane (HFSLM) was carried out on pharmaceuticals samples comprising of cough syrups (CS1 and CS2) and an antiinflammatory product (AI). The active ingredients targeted in the extraction process were diphenylhydramine (DPH), chlorpheniramine (CPA) [(S)-γ-(4-chlorophenyl)-N,N-dimethyl-2-pyridinepropanamine maleate sal...

Aptamers are an interesting alternative to antibodies in pharmaceutics and biosensorics, because they are able to bind to a multitude of possible target molecules with high affinity. Therefore the process of finding such aptamers, which is commonly a SELEX screening process, becomes crucial. The standard SELEX procedure schedules the validation of certain found aptamers via binding experiments,...

−Five pretreatment methods, namely chemical, acid, heat-shock, freezing and thawing, and base, were evaluated for the enrichment of hydrogen-producing bacteria in anaerobic granulated sludge, which will be subsequently used as seed in biological hydrogen production. All the pretreatments showed positive effects towards improving hydrogen (H 2 ) generation by the microbial population with higher...

Within relevance theory the two local pragmatic processes of enrichment and loosening of linguistically encoded conceptual material have been given quite distinct treatments. Enrichments of various sorts, including those which involve a logical strengthening of a lexical concept, contribute to the proposition expressed by the utterance, hence to its truthconditions. Loosenings, including metaph...
