A multicentre in vitro evaluation of piperacillin/tazobactam in Germany

Abstract: In a multicentre study in Germany 10584 fresh clinical aerobic isolates were tested for susceptibility to piperacillin (30 micrograms or 100 micrograms discs) and piperacillin/tazobactam (30 micrograms/10 micrograms or 100 micrograms/10 micrograms discs). Preliminary breakpoints for piperacillin/tazobactam according to the German standard methods (Deutsches Institute fur Normung) were: Resistant: inhibition zone or = 64 mg/l. Susceptible: inhibition zone > or = 22 mm; MIC D or = 4 mg/l. For comparison, the National Committee for Clinical Laboratory Standards (USA) breakpoints for enterobacteria (100/10 micrograms/disc) are: Resistant: inhibition zone or = 128/4 mg/l. Susceptible: inhibition zone > or = 21 mm; MIC 14 mm and found that an additional 55.7% of resistant/intermediate Enterobacteriaceae and 91.0% of resistant/intermediate S aureus were susceptible to piperacillin/tazobactam, giving totals for susceptibility of 96.1% for Enterobacteriaceae and 98.1% for S aureus.

\(\kappa \)-Circulant Maximum Variance Bases

Abstract: Principal component analysis (PCA), a well-known technique in machine learning and statistics, is typically applied to time-independent data, as it is based on point-wise correlations. Dynamic PCA (DPCA) handles this issue by augmenting the data set with lagged versions of itself. In this paper, we show that both, PCA and DPCA, are a special case of \(\kappa \)-circulant maximum variance bases. We formulate the constrained linear optimization problem of finding such \(\kappa \)-circulant bases and present a closed-form solution that allows further interpretation and significant speed-up for DPCA. Furthermore, the relation of the proposed bases to the discrete Fourier transform, finite impulse response filters as well as spectral density estimation is pointed out.

Filling method for dense flow conveyor systems

Abstract: The material is fed by a cellular wheel sluice (2) into the dense-flow conveyor (11) via a tubular store (3). The material flow is reduced during filling of the store and increased after this process has ended. The store is pressure- charged, and the store volume is at a fixed ratio to the cycle of the closure valve (1). During the filling process, the store is ventilated via a ventilation line (17), which is closed together with the closure valve.

Device for supplying several pneumatic transport systems with transport gas under pressure has blow-off line with blow-off control element, excessive flow and pressure maintenance control unit

Abstract: The device has a central supply gas line into which several parallel, selectively operable pressure generators (3a-3c) open, from which parallel selectively operable transport lines (6a-6c) emanate, each of which contains a transport system (2a-2c) and to which is connected a blow-off line (7) with a blow-off control element and an excessive flow and pressure maintenance control unit (10). The excessive flow and pressure maintenance control unit is a pneumatic device.
