INTRODUCTION Regional citrate anticoagulation (RCA) for continuous renal replacement therapy is widely used in intensive care units (ICUs). However, concern exists about the safety of citrate in patients with liver failure (LF). The aim of this study was to evaluate safety and efficacy of RCA in ICU patients with varying degrees of impaired liver function. METHODS In a multicenter, prospectiv...

Pengaturan kecepatan motor dilakukan dengan mengubah tegangan input, ataupun frekuensi yang terdapat pada motor. Maka hal lebih mungkin adalah sumber stator. Inverter bisa digunakan sebagai pengontrol dapat mengatur induksi, topologi inverter diode clamped multilevel tetapi masih mengandung harmonisa cukup tinggi, sehingga memerlukan filter untuk mengurangi besarnya harmonisa. Filter pasif L-C-...

This paper reports on the recovery of zinc, cobalt and manganese by two-step leaching of zinc-plants purification residue with sulfuric acid. The residue, hot filter press cake (HFC), contains 14 % ZnO, 4.8 % Co3O4 and 22.9 % MnO. Effects of different parameters are determined and used to optimize the process. With acid to hot filter press cake (HFC) stoichiometry of 0.85, acid concentration of...

This article gives results on fixed basis frame valued neighborhood topological groups and stratified neighborhood topological groups, includes some characterization theorems, and presents the uniformizability of stratified neighborhood topological groups within the unified approach of Gutiérrez García, DePrada Vicente, and Šostak. It is shown that for a frame L, the category L-NGrp is topologi...

Several adaptive LMS L-filters, both constrained and unconstrained ones, are developed for noise suppression in images and being compared in this paper. First, the location-invariant LMS L-filter for a nonconstant signal corrupted by zero-mean additive white noise is derived. Subsequently, the normalized and the sign LMS L-filters are studied. It is shown that both these filters turn to be iden...

This paper presents a comparison between piezoelectric filtering and passive LC integrated into an HF class L?Piezo inverter. inverter is variant of ?2 where the second harmonic carried out by resonator. Piezoelectric filters are well known in signal domain (RF filtering), but their use field power electronics, as temporary energy storage element, rather recent. In piezoelectricity has mainly b...

In this report, we propose a non-separable twodimensional (2D) Lossless Symmetric Short Kernel Filter (L-SSKF) for image compression. Filter characteristics of our proposed L-SSKF are the same as those of conventional 2D L-SSKF based on applying 1D L-SSKF twice but our coding performance is better due to reduction of rounding effects. Simulation results confirm effectiveness of our proposed L-S...

slow sand filtration (s.s.f) is a main process in the water treatment technology and generally considered as most appropriate for application in rural and small urban areas in developing countries. however, performance of the s.s.f is very sensitive to high turbidity levels. therefore, pretreatment is necessary for such waters. horizontal - flow roughing filtration (hfrf) and direct horizontal ...

OBJECTIVES To explore the pharmacokinetics (PK) and pharmacodynamics (PD) of micafungin in patients undergoing continuous venovenous haemofiltration (CVVH). PATIENTS AND METHODS Ten patients receiving CVVH treated with 100 mg/day micafungin were included (April-December 2012). CVVH was performed using polyethersulphone or polysulphone haemofilters. Dialysis membranes were not changed on sampl...
