The present paper discusses the pressure loss through the spiral heat exchanger (HX) proposed in the ELSY (European-Lead cooled SYstem) project. An approach based on CFD (Computational Fluid Dynamics) using the commercial code ANSYS CFX has been used for exploring the flow through the HX. The HX consists of perforated double inner and double outer walls, as well as an innovative spiral design o...

For more than 40 years, electrical stimulation procedures for unilateral recurrent laryngeal nerve paresis (URLNP) therapy have been proposed. However, it is unclear whether electrical stimulation therapy is effective for URLNP patients. In this study we compare the outcome of traditional voice exercise treatment (VE) with electrical stimulation-supported voice exercise (ES). A total of 90 URLN...

Graphite fluoride (CFx) cathodes coupled with lithium anodes yield one of the highest theoretical energy densities (>860 Wh/g) among primary batteries. In practice, observed discharge voltage (~2.5 V) is significantly lower than thermodynamic limits (>4.5 V), rate low, and so far Li/CFx has only been used in Understanding mechanism at atomic length scales will improve practical CFx density, cap...

Background and purpose: Recently, release of pollutants such as pharmaceuticals to the environment becomes one of the most important problems for soil and water. The present study was conducted to introduce walnut shell-based activated carbon (AC) as a new low-cost adsorbent for the removal of cephalexin (CFX) antibiotic from aqueous solutions. Materials and Methods: This study was conducted...
