what to look for in abbas abad pool? a lake in middle of the forest on the mountain heights with an encircled building with waters and a garden ashore? why are the trees cut and used to build a garden? and what is the purpose of placing a lake on a dominant and deep valley over the khazar sea. today, green trees are grown in abbas abad garden and no sign of landscaping or water features can be ...

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...

in this work we introduce a practical use of synthesized schiff base metal complex in sensing application. a new perchlorate-selective electrode based on the complex n, n'-4-nitro-phenylmethanebis-(salicylaldiminato) copper (ii) [cul] as the membrane carrier was developed. the electrode exhibits a good  nernstian slope of -55.0 ± 1.0 mv/decade and a linear range of  for perchlorate. the limit o...

there are many evidences that human serum paraoxonase activity modifies plasma lipid profile and paraoxonase has an antiatherogenic property. non-selective beta-blockers affect plasma lipid profile too, but they have atherogenic property when patients take these drugs in long term. in this study the effect of propranolol, a non-selective beta-blocker, on paraoxonase activity was investigated. l...
