conclusions rotem can be used to detect postoperative hemostatic changes following cardiac surgery appropriately and can be useful to choose suitable blood products that may reduce the need for blood transfusion, contributing to better patient blood management. background coagulopathy after cardiopulmonary bypass (cpb) may lead to increased morbidity and mortality. routine conventional coagulat...

background and objective: parkinson's disease (pd) is a neurodegenerative disease with selective damage of mesencephalic dopaminergic neurons. due to the protective, anti-inflammatory, and antioxidant effect of hypericum perforatum (hp), this study was undertaken to assess dose-dependent effect of hp hydroalcoholic extract on motor imbalance following intrastriatal injection of 6-hydroxydo...

Rotational spectra have traditionally been measured without a concurrent means of differentiating the molecular constituents of the sample. Here, we present an all-optical multipulse experiment that allows the correlated measurement of rotational and mass or photoelectron spectra by combining Fourier transform rotational coherence spectroscopy with resonance-enhanced multiphoton ionization. We ...

in this paper, the effects of transverse cracks on rotating shaft were studied. according to earlier works, crack shaft failure decrease the critical speed of the shaft and also exhibit a nonlinear vibration behaviour leading to increases the amplitude of 1x and 2x harmonics (first and second order of rotational speed in torsional vibration). this suggests that the application of order analysis...

BACKGROUND The failure to restore mechanical alignment and appropriate rotational axis intraoperatively has been described as one of the most common causes of implant failure in total knee arthroplasty (TKA). Both conventional and computer-assisted TKA have their limitations. Patient-specific jigs (PSJ) offer a possible alternative method for TKA. The aim of this study was to investigate if the...

Shift work can be attributed to some of social and health problems in working community. In this study an attempt was made to study the sleep and wakefulness patterns in nurses engaged in rotational and non-rotational shift work in a hospital through sleep charts. It was observed that non-rotational workers enjoyed more frequent and longer naps and had less disturbances in their sleep patterns ...

We study the dynamical heterogeneity and glassy dynamics in a kinetically constrained lattice-gas model which has both translational and rotational degrees of freedom. We find that the rotational relaxation time tracks the structural relaxation time as density is increased whereas the translational diffusion constant exhibits a strong decoupling. We investigate distributions of exchange and per...

An analytical approach for the estimating of critical seismic acceleration rock slopes was proposed in this study. Based on 3D horn failure model, coefficient conducted with modified Hoek–Brown (MHB) criterion framework upper-bound theory first time. The nonlinear is incorporated into three-dimensional rotational mechanism, and a generalized tangent technique introduced employed to convert line...
