the imported willow leaf beetle, plagiodera versicolora is one of the main pests of forest trees worldwide including iran. activities of α- and β-glucosidases in the midgut of p. versicolora adults were studied in this research. the results showed a higher α- glucosidase activity of adultsthan β-glucosidase. the optimal phs for α- and β-glucosidases activities were found to be 6 and 9, respecti...

It is known that the α-β-filter is an efficient-simple estimation scheme for the motion control. However, the estimation performance heavily depends on the parameters α and β values. This paper presents a fast real-time genetic algorithm (GA) to adapt αβ filter. In the proposed method, the parameters α and β values are adjusted in real-time by GA to meet some specifications. The simulation resu...

In order to discriminate situation awareness (SA) levels on the basis of SA-sensitive electroencephalography (EEG) features, high-SA (HSA) group and low-SA (LSA) groups, which are representative two SA levels, were classified according global assessment technology (SAGAT) scores measured in multi-attribute task battery (MATB) II tasks. Furthermore, three types EEG namely, absolute power, relati...

Proteins frequently assume complex three-dimensional structures characterized by marginal thermodynamic stabilities. In this scenario, deciphering the folding code of these molecular giants with clay feet is a cumbersome task. Studies performed in last years have shown that the interplay between backbone geometry and local conformation has an important impact on protein structures. Although the...

In this paper, the authors summarize the results of a parametric study devoted to evaluate the seismic behavior of low to medium rise regular special moment-resisting steel frames with hysteretic energy dissipation devices mounted on chevron steel bracing. For that purpose, 270 different building models were designed considering typical story heights and bay widths used in Mexican practice. The...

The aim of this study was to analyze the anatomical characteristics of patients with ruptured abdominal aortic aneurysms (AAAs) using computed tomography (CT) aortography in order to determine the risk factors for rupture.We retrospectively reviewed the CT aortography findings and medical records of patients with ruptured AAAs who underwent CT aortography between February 2002 and December 2014...

Objective: Eucalyptus (Fam. Myrtaceae) is a medicinal plant and various Eucalyptus species possess potent pharmacological actions against diabetes, hepatotoxicity, and inflammation. This study aims to investigate essential oil compositionfrom leaves and flowers of E. microthecaand E. viminalisleavesgrowing in the Southeast of Iran. Materials and Methods: The aerial parts of these plants were co...

A fundamental question in protein science is what is the intrinsic propensity for an amino acid to be in an α-helix, β-sheet, or other backbone dihedral angle ( ϕ-ψ) conformation. This question has been hotly debated for many years because including all protein crystal structures from the protein database, increases the probabilities for α-helical structures, while experiments on small peptides...

estrogen (e2) has neuroprotective effects on blood-brain-barrier (bbb) after traumatic brain injury (tbi). in order to investigate the roles of estrogen receptors (ers) in these kind of effects, er-α antagonist (mpp) and, er-β antagonist (phtpp), or non-selective estrogen receptors antagonist (ici 182780) were administered as regulators of cns cytokines levels and neuroinflammation after tbi. m...
