Resistance to antimicrobial agents is responsible for major social and economic losses. The World Health Organization estimated 700,000 global deaths a year due resistance. use of layered double hydroxides (LDHs) as antibacterial materials could present way reduce the risk bacterial infections resistance, by partial release metallic ions in aqueous dispersion. dissolution different synthetic LD...

background : the sequencing batch reactor (sbr) is one of the most widely used systems in sewage treatment because of the simplicity of the process, flexibility of operation in the removal of nutrients, and the ability to be used in different scales. the aim of this study was to evaluate the efficiency of the sbr in the removal of organic matter (nitrogen and phosphorus) from synthetic wastewat...

1 Einführung Der Standard GSM [1] bildet eine Grundlage für digitale Mobilfunknetze. Der Verbindungsaufbau zur Mobilstation (MS) eines Teilnehmers erfolgt mit vorheriger Anfrage an eine zentrale Datenbank (Home Location Register, HLR). GSM-Netze haben eine verteilte Netzstruktur. Das Versorgungsgebiet wird in Lokalisierungsgebiete (Location Areas, LA) aufgeteilt. Diese Gebiete werden durch Verm...

Several variants of high-level replacement (HLR) and adhesive categories have been introduced in the literature as categorical frameworks for graph transformation and HLR systems based on the double pushout (DPO) approach. In addition to HLR, adhesive, and adhesive HLR categories several weak variants, especially weak adhesive HLR with horizontal and vertical variants, as well as partial varian...

UNLABELLED INTRODUCTION Despite progress in reconstructive techniques, rebuilding portions of the thorax remains challenging, in particular when large resections, contamination or infection are involved. No other cases of thoracic reconstruction in trauma patients with biological prosthesis have been described since now. METHODS We report a case of thoracic reconstruction in highly infecte...

 The aquatic fern Azolla, a small-leaf floating plant that lives in symbiosis with a nitrogen fixing cyanobacteria (Anabaena), is an outstanding plant, thanks to its high biomass productivity along with its tremendous rate per unit area for nitrogen-fixation.  The present study investigates the potential growth of Azolla in secondary effluents for removal of COD, phosphorus, and nitrogen. Resul...
