In this paper, the buckling and vibration behaviour of functionally graded flexoelectric nanobeam is examined. The vibration and buckling formulations of functionally graded nanobeam are developed by using a new theory that’s presented exclusively for flexoelecteric nano-materials. So by considering Von-Karman strain and forming enthalpy equation based on displacement, polarization and electric...

We explored the associations of job strain with sleep and alertness of shift working female nurses and nursing assistants. Participants (n=95) were recruited from the Finnish Public Sector Study, from hospital wards that belonged to the top or bottom quartiles on job strain. Participants' own job strain was at least as high in high-strain group or low in low-strain group as the ward's average. ...

BACKGROUND Opening of an occluded infarct related artery reduces infarct size and improves survival in acute ST-elevation myocardial infarction (STEMI). In this study we performed tissue Doppler analysis (peak strain, displacement, mitral annular movement (MAM)) and compared with visual assessment for the study of the correlation of measurements of global, regional and segmental function with f...

An actinomycete strain, ID05-A0528(T), was isolated using the SDS-yeast extract pre-treatment method from soil under mahogany (Swietenia mahogani) trees in West Timor, Indonesia, and was examined by using a polyphasic taxonomic approach. Chemotaxonomic and phylogenetic characterizations demonstrated that the novel strain belongs to the genus Dietzia. 16S rRNA gene sequencing studies showed that...

Abstract. In this study, the Finite Element (FE) simulation of an initially pre-deformed DC-5 steel cruciform specimen has been carried out and compared to experimental results. A new geometry sample with local reinforcements without thickness reduction allows distribution plastic deformation gets high strains in its gauge region. The is divided into two steps. first one introduces initial arms...

Background: Right ventricular (RV) dysfunction after left ventricular assist device (LVAD) implantation significantly complicates post-device management and has been shown to be associated with increased mortality. Pre-operative identification of patients who may develop post-LVAD RV dysfunction is challenging. This study was designed to evaluate pre-operative echocardiographic speckle tracking...

To meet the strain sensitivity requirements [1], [2] of the Laser Interferometer Gravitational Wave Observatory (LIGO), the laser frequency and amplitude noise must initially be reduced by a factor of 1000 in the pre-stabilized portion of the interferometer [3]. A control system was implemented to provide laser noise suppression, data acquisition interfaces, diagnostics, and operator control in...

male guinea pigs show high susceptibility to burkholderia mallei and have been used as animal models in glanders studies. the purpose of our study was to elucidate glanders comparative pathogenesis in guinea pigs. we present here the histological changes and bacterial isolation that develop over time in guinea pigs inoculated intraperitoneally (ip) with two strain of b. mallei. ten male guinea ...
