Characterization of the inhibitor-resistant SHV β-lactamase SHV-107 in a clinic...

The clinical Klebsiella pneumoniae INSRA6884 strain exhibited nonsusceptibility to all penicillins tested (MICs of 64 to>2,048 g/ml). The MICs of penicillins were weakly reduced by clavulanate (from 2,048 to 512 g/ml), and tazobactam restored piperacillin susceptibility. Molecular characterization identified the genes blaGES-7 and a new -lactamase gene, blaSHV-107, which encoded an enzyme that differed from SH...

Biochemical study of a new inhibitor-resistant beta-lactamase, SHV-84, produced...

Drilling composite laminates with a laser Nd:Yag - delamination damage assessment

This work shows the results of laminate drilling using an Nd-YAG laser, a nonconventional method. Advantages in damage reduction are discussed.

Tool Geometry Evaluation for Carbon Reinforced Composite Laminates

The subject of this work is the study of drilling conditions and tool geometry in order to minimize delamination damage. Delamination is evaluated by enhanced radiography and damage criteria applied to compare different tools and cutting parameters.

Cornoside and other constituents from the latex of Parahancornia amapa (Hub.) D...

Latex of Parahancornia amapa which is known as "amapa milk" in folk medicine was extracted with hexane, dichloromethane and methanol. From the hexane and dichloromethane were identified mixtures of 3-O-acyl lupeol esters such as identified previously. In the methanol extract, a large amount of carbohydrates, the phenylethanoid glucoside known as cornoside, other phenylethanoids derivatives and methylmyoinositol...
