Amp C beta-lactamases are a type of cephalosporinase enzymes belonging to Class C of Ambler’s structural classification, while assigned to group 3 in the functional classification scheme of Bush (Ambler, 1980; Bush et al., 1995). These enzymes can be either chromosomal or plasmid encoded conferring resistance to both oxyimino (cefotaxime, ceftazidime, ceftriaxone) and 7-α methoxy cephalosporins...

in order to study the effect of vermicompost containing copper oxide and zinc oxide nanoparticles on was beans, in an experiment factorial were done based on a randomized complete block design in three replications. the experiment treatment were as follows: nanoparticles in 4 levels (0, 0.4, 0.8 and 1.2 g/kg weight of substrate), vermicompost in 3 levels (2.5, 5 and 7.5 g/kg-1 weight of substra...

I study the mobility and economic outcomes of European immigrants and their children in 19th-century Argentina, the second largest destination country during the Age of Mass Migration. I use new data linking males across censuses and passenger lists of arrivals to Buenos Aires. First-generation immigrants experienced faster occupational upgrading than natives. Occupational mobility was substant...

An exact expression for the determinant of the splitting matrix is derived: it allows us to analyze the asymptotic behaviour needed to amend the large angles theorem proposed in Ann. Inst. H. Poincaré, B-60, 1, 1994. The asymtotic validity of Mel-nokov's formulae is proved for the class of models considered, which include polynomial perturbations. §1. Introduction. Recently V. Gelfreich noted t...

Parasabella Bush, 1905 is reintroduced as a replacement name for Demonax Kinberg, 1867 (Annelida: Polychaeta: Sabellidae) which is a junior homonym of Demonax Thomson, 1860 (Insecta: Coleoptera: Cerambycidae).

Abstract The marine engine is one of the core devices ship. With continuous progress science and technology, engines are developing towards high power density, related tribological problems more prominent. As most typical friction pairs engines, crankshaft-bearing bush bears loads presents a trend increased wear. By studying wear behavior bearing bush, it possible to deeply grasp mechanism, spe...
