PURPOSE To evaluate the influence of sclerotomy use during vitrectomy (vitreous cutter, illumination probe, or infusion-line entrance) on postoperative vitreous incarceration using an experimental model of vitrectomized eye. MATERIALS AND METHODS Experimental, randomized, and observer-masked study in which 23-gauge transconjunctival sutureless vitrectomy was performed in cadaveric pig eyes. P...

Dam breaks of landslide dams are always accompanied by large numbers of casualties, a large loss of property, and negative influences on the downstream ecology and environment. This study uses the Jiadanwan landslide dam, created by the Wenchuan earthquake, as a case study example. Several laboratory experiments are carried out to analyse the dam-break mechanism of the landslide dam. The differ...

conclusions administration of two different doses of intravenous ondansetron, 6 mg and 12 mg, significantly attenuates spinal induced hypotension, bradycardia and shivering compared to the control saline group. however, the hemodynamic profiles and shivering in experimental groups were not statistically different. results demographic data were not statistically different among groups. hr was st...

The transition to multicellularity was a major step in the evolution of large, complex life on Earth (Maynard Smith and Szathmáry 1995). Unlike other major evolutionary transitions, which have occurred only once (e.g., prokaryotes to eukaryotes), multicellularity has evolved multiple times in diverse lineages including archaea (Jahn et al. 2008), bacteria (Velicer and Vos 2009; Overmann 2010; S...

test anxiety is one of key factors which weaken the student’s morale and confidence and reduce their creativity and gradually become the permanent personal characteristic and mostly results in feeling of inadequacy. human’s locus of control is usually roots in personal belief system about the causes of the different personal experience and the causes of the success or failure, so it has great e...

objectives:the purpose of this study was to investigate of effects of sensory integration therapy (sit) on social interaction and sensory and motor performance in children with autism spectrum disorders (asd). methods:24 children with asd (22 boys, 2 girls), aged 6-12 years that matched on iq and gender, were randomly assigned to an experimental or control group. we requested participants of th...

Self-reliant digital systems (SDS) can adapt to changing circumstances and environments, evaluate complex situations, make decisions optimise processes. In this context, work processes also change, since SDS are controlled by workers but partly out of control, that is, processing information independently without worker influence. It be expected handling interacting with impact workers’ percept...
