Glass fiber catalysts for total oxidation of CO and hydrocarbons in waste gases

Different glass fibers in woven forms were used as supports for Pt and Pd catalysts and were tested in toluene and CO total oxidn. at atm. pressure. The catalytic activity and the ignition-extinction temps. were investigated in relation to chem. compn. of the supports, the types of active metal used (Pt, Pd), and the surface concn. of the metal. The exptl. results suggest the modified glass fibers as suitable supports for efficient catalysts for complete oxidn. The catalysts can be used at moderate temps. (150-250 Deg) and at high gas hourly space velocity (GHSV = 30,000 h-1). The main design parameters of structured catalytic bed reactors, based on glass fiber catalyst, are discussed.

Cryopyrin-Associated Periodic Syndrome: An Update on Diagnosis and Treatment Response

Cryopyrin-associated periodic syndrome (CAPS) is a rare hereditary inflammatory disorder encompassing a continuum of three phenotypes: familial cold autoinflammatory syndrome, Muckle-Wells syndrome, and neonatal-onset multisystem inflammatory disease. Distinguishing features include cutaneous, neurological, ophthalmologic, and rheumatologic manifestations. CAPS results from a gain-of-function mutation of the NLRP3 gene coding for cryopyrin, which forms intracellular protein complexes known as inflammasomes. Defects of the inflammasomes lead to overproduction of interleukin-1, resulting in inflammatory symptoms seen in CAPS. Diagnosis is often delayed and requires a thorough review of clinical symptoms. Remarkable advances in our understanding of the genetics and the molecular pathway that is responsible for the clinical phenotype of CAPS has led to the development of effective treatments. It also has become clear that the NLRP3 inflammasome plays a critical role in innate immune defense and therefore has wider implications for other inflammatory disease states

Sprachgeographische Aspekte der Morphologie und Verschriftung in schweizerdeutschen Chats.

The regional chat-rooms in Switzerland show an extremely high portion of dialectal contributions (up to 90%). This non-standardized spontaneous writing of a dialectal language still reflects the geolinguistic distribution described in the linguistic atlas of German speaking Switzerland SDS (1962-1997) based on recordings of the 1940s and 1950s. This paper shows some reflexes of this geolinguistic distribution in four chat-rooms. The graphemic representation of the ending vowel of infinitives clearly confirms the traditional structure. Deviating e-graphemes in chat-rooms of alpine regions can be rated as common Swiss German variants for centralized vowels. On the other hand ä-graphemes in chat-rooms of the Swiss midlands are to be rated as marking of the phonetic deviation from the standard German pronunciation. This variation is not only found in inherited words, but also in neologisms with an almost identical distribution. The SDS illustrates a distribution for the use of t-endings in the 2nd and 3rd singular of sein 'to be'. These t-flexives cannot be found anymore in midland chat-rooms. They appear only in alpine chat-rooms, and there they become morphologized in a new way. The dialectal writing of neologisms confirms the validity of the principles for the Standard German writing
