Manganese plays a key role in the health of human beings therefore, its determination is very important in medical fields. In this regards, a novel coated graphite electrode was constructed for determination of manganese (II) by using zolpidem as an ionophore, for the first time. The best performance was obtained of the membrane composition of PVC (32%), Potassium tetrakis (4-chlorophenyl) bora...

Background and Objective: The purpose of this study was to compare the effectiveness of the non-computerized training package of working memory (WM) and selective attention with captain’s Log software on the components of WM. Materials and Methods: The present study was conducted in a quasi-experimental design, with non- random targeted sampling, and pre-test, post-test, follow-up, and control...

Perceptual load theory successfully replaced the early vs. late selection debate by appealing to adaptive control over the efficiency of selective attention. Early selection is observed unless perceptual load (p-Load) is sufficiently low to grant attentional "spill-over" to task-irrelevant stimuli. Many studies exploring load theory have used limited display durations that perhaps impose artifi...

In this paper we will show that Ikema, a dialect of Miyako Ryukyuan, has a three-tone system, where three tonal classes, Types A, B, and C, are lexically distinguished, contra the previous studies which have claimed that it has a two-tone system. The results of our quantitative analysis of production data also revealed that Type A words are remarkably small in number, indicating that Type A wor...

quercetin, a ubiquitous flavonol, represents a promising leading drug for development of new chemotherapeutic agents. however, its limited cytotoxicity to cancer cells hampers its clinical use. in order to obtain novel quercetin derivatives with superior cytotoxicity, seven alkylated quercetin derivatives were synthesized. solubility of these derivatives was determined by turbidimetry. cytotoxi...

| Damage detection using guided Lamb waves is an important tool in Structural health Monitoring. In this paper, we outline a method of obtaining Lamb wave modes in composite structures using two dimensional Spectral Finite Elements. Using this approach, Lamb wave dispersion curves are obtained for laminated composite structures with different fibre orientation. These propagating Lamb wave modes...
