Presentations of Kan extensions of category actions provide a natural framework for expressing induced actions, and therefore a range of different combinatorial problems. Rewrite systems for Kan extensions have been defined and a variation on the Knuth-Bendix completion procedure can be used to complete them – when possible. Regular languages and automata are a useful way of expressing sets and...

Although hypersaline environments pose challenges to life because of the low water content (water activity), many such habitats appear to support eukaryotic microbes. This contribution presents brief reviews of our current knowledge on eukaryotes of water-column haloclines and brines from Deep Hypersaline Anoxic Basins (DHABs) of the Eastern Mediterranean, as well as shallow-water hypersaline m...

In the category Top0 of T0-spaces and continuous maps, embeddings are just those morphisms with respect to which the Sierpiński space is Kan-injective, and the Kan-injective hull of the Sierpiński space is the category of continuous lattices and maps preserving directed suprema and arbitrary infima. In the category Loc of locales and localic maps, we give an analogous characterization of flat e...

The mercury and antibiotic resistance of 338 strains of Escherichia coli isolated from hospital patients was determined. Resistance to mercury was found in 58.6% of the isolates. The frequencies of resistance to streptomycin (Sm), tetracycline (Tc), chloramphenicol (Cm), kanamycin (Kan), cephaloridine (Cer), and gentamicin (Gm) were 66.3, 60.3, 56.5, 42.9, 32.1, and 1.5%, respectively. Among th...

Die skrywer glo dat opnames onder hoërskoolleerlinge waardevoUe demografiese inligting kan voorsien. Die uitvoerbaarheid hiervan is in die veld getoets. In die bespreking van die bevindings stel die skrywer ’n stelsel vir die registrasie van geboortes en sterftes in nasionale state voor waarin die gemeenskapsverpleegkundige en piaaslikc kliniek gebruik word. Watter wyse van registrasie ook op b...

Capsule gene (cps) expression, which normally occurs at low levels in Escherichia coli lon+ cells, increased 38-fold in lon+ cells carrying a Tn10::delta kan insertion mapping to 24 min on the E. coli chromosome. Null mutations in rcsA, rcsB, or rcsC abolished the effect of the Tn10::delta kan insertion. Sequencing of both sides of the Tn10::delta kan insertion localized the insertion to the pr...

It is widely believed that the results in Duffie and Kan (1996) provide the necessary and sufficient conditions for a multifactor model of the term structure of interest rates to admit an affine representation. It is shown here that, in fact, only sufficient conditions are given by Duffie and Kan, and there are families of affine models that do not fall into the Duffie-Kan characterisation. A m...

The nucleus basalis magnocellularis (nbm)-lesioned rat is considered to be a model of the cholinergic dysfunction observed in the cerebral cortices of Alzheimer's disease patients. The cholinergic markers, acetylcholine release and choline acetyltransferase activity, were decreased in the cerebral cortex of the nbm-lesioned rat. Kangenkaryu (KAN), a Chinese traditional medicine, is a typical pr...

We present a cubical type theory based on the Cartesian cube category (faces, degeneracies, symmetries, diagonals, but no connections or reversal) with univalent universes, each containing Π, Σ, path, identity, natural number, boolean, pushout, and glue (equivalence extension) types. The type theory includes a syntactic description of a uniform Kan operation, along with judgemental equality rul...

Idag finns det säkra och effektiva behandlingar mot många sjukdomar. Läkemedel är den vanligaste behandlingsformen i sjukvården och under 2006 hämtade sex miljoner svenskar (68%) ut ett eller fler recept på ett apotek i Sverige. Även om läkemedelsbehandling har många positiva effekter kan även oönskade och skadliga effekter vid läkemedelsbehandling uppkomma, dvs. läkemedelsbiverkningar. Innan e...
