Background: Lighting is a basic need for human beings and affects their physical, physiological, and psychological behavior. The required level of lighting for visual performance must be provided in order to ensure health and wellbeing. Students spend much of their time studying in libraries, and thus, sufficient lighting is necessary in libraries. Therefore, the aim of the present study was to...

The aim of this study was to evaluate the relationship between abnormal expression of E-cadherin (E-CAD) and the extracapsular extension of tumors, lymph node involvement and the presence of metastasis in various types of thyroid cancers. Histopathological specimens of 35 benign thyroid lesions and 122 malignant tumors (papillary, follicular, poorly differentiated and undifferentiated cancers) ...

The prevalence of coccidia infection in goats was evaluated in Western Pomerania (Poland) and West Ukraine Province. A total number of 311 goats were examined: 173 from Western Pomerania, including 139 kids (up to 6 month old), and 138 from the Lviv region including 93 juveniles. The study was based on two flotation methods, which helped to establish the number of oocysts in 1g of feces (OPG): ...

This paper proposes two new classes of imperfect repair models. The failure process without repair is supposed to be a Non Homogeneous Poisson Process (NHPP). The repair e ect is characterized by the change induced on the failure intensity before and after failure. In the rst class of models, repair e ect is expressed by a reduction of failure intensity. In the second class, repair e ect is exp...

BACKGROUND The objectives of the present study were to compare time spent cycling, exercise intensity, and time spent in moderate- (MPA) and vigorous intensity physical activity (VPA) when cycling on an E-bike and a conventional bicycle on two "cycling-to-work" routes with differences in topography, defined as a hilly and a flat route. METHODS Eight adults (23-54 years, two women) cycled outd...

We describe LaueView, a code for processing the measured intensity data in Laue X-ray di raction experiments to obtain corrected structure amplitudes for each re ection that take account of the various distortion e ects. The resulting corrected intensity data can then be used to recover the molecular structure by isomorphous re nement or by solution of the phase problem. We describe the key num...

The hypoxic exercise test combining a 4,800-m simulated altitude and a cycloergometer exercise at 30% of normoxic maximal aerobic power (MAP) is used to evaluate the individual chemosensitivity to hypoxia in submaximal exercise conditions. This test allows the calculation of three main parameters: the decrease in arterial oxygen saturation induced by hypoxia at exercise (ΔSa(e)) and the ventila...
