Separation methods for rare earth elements (REE) are predominantly based on solvent extraction procedures. These methods are low in metal selectivity and generate large amounts of waste resulting in high capex and opex costs. Molecular Recognition Technology (MRT) is a much simpler green chemistry process that uses no organic solvents and carries out separations with highly metal-selective Supe...

Media selection has become a more complex problem because of the fast development of Information and Communication Technology. However, there is little quantified work on the tools for media selection decisions. The three main tools available are Media Richness Theory (MRT) [1], Social Influence Perspectives (SIP) [2], and Media Fitness Framework (MFF) [3,4]. MFF is a combination of the factors...

The expansion of 802.11 AP deployment provides opportunistic Wi-Fi access in underground mass rapid transit (MRT) system. However, such vehicular network faces the challenge of limited time for the MS on the train to connect the base station at the station. Therefore, to maximize the throughput within these several tens of seconds becomes crucial to the network. To achieve this goal, we propose...

Ziel: Patienten mit einem Marfan-Syndrom benötigen eine regelmäßige Bildgebung zur Detektion von Aneurysmen der Aorta ascendens. Ziel dieser Studie war es, die Reproduzierbarkeit von Messungen des Sinus valsalvae mittels Cine-MRT und Echokardiografie an Patienten mit Verdacht auf Marfan-Syndrom zu untersuchen. Material und Methoden: 51 konsekutive Patienten mit Verdacht auf Marfan-Syndrom wurde...

Mental rotation task (MRT) incorporates elements of spatial abilities, important in many professions, with people of both genders involved. Importantly, these are the areas where spatial tasks might be performed for long time periods; thus adverse effects of mental fatigue are highly unwanted. Substantial variation of MRT performance in relation to estrogen levels has been observed in many stud...

OBJECTIVES This study is designed to evaluate the mechanical stability of orthodontic mini-implants with vertical grooves in rabbits. MATERIALS AND METHODS This study was done from March 2011 to February 2012 in Dental Research Institute of Seoul National University. Thirty-two mini-implants in the control group and 32 in the rotation bump (RB) group were inserted in the tibias of 16 rabbits ...

The seven-transmembrane receptor Smoothened (Smo) is the major component involved in signal transduction of the Hedgehog (Hh) morphogens. Smo inhibitors represent a promising alternative for the treatment of several types of cancers linked to abnormal Hh signaling. Here, on the basis of experimental data, we generated and validated a pharmacophoric model for Smo inhibitors constituted by three ...
