BACKGROUND Work-related fatigue of the lower extremities is a known cause of lost productivity and significant employer costs. Common workplace solutions to reduce fatigue levels include anti-fatigue matting, shoe orthoses, or sit/stand work stations. However, assessment of these anti-fatigue measures within the workplace has been limited. METHODS This was a cross sectional study in an automo...

According to the equivalent light hypothesis, molecular defects in the photoreceptor lead to a continuous activation of the photoreceptor cascade in a manner equivalent to real light. The consequences in diseases such as retinitis pigmentosa (RP) are as disruptive to the cells as real light. Two forms of the equivalent light hypothesis can be distinguished: strong - mutations in rhodopsin or ot...

The hypothesis that fluorescence in scorpions functions in the detection of ultraviolet light was tested. We reduced the fluorescence of scorpions by prolonged exposure to ultraviolet light on a 16:8 h light:dark cycle and compared their activity levels and light environment choices to unmodified scorpions in simple arenas that were half in shadow and half exposed to light. Three different ligh...

California newts (Taricha torosa) are capable of locomotion in both aquatic and terrestrial environments. The transition between swimming and terrestrial walking was examined by videotaping individual Taricha walking both up and down a ramp, inclined at 15 degrees to the horizontal, that had its lower end immersed in water and its upper end out of the water. When ascending the ramp, California ...

Oral grooming is common in cats, as in rodent and bovid species where grooming has been shown to be effective in removing lice and ticks. In Experiment 1, we examined the effectiveness of oral grooming in removing fleas which are the main ectoparasite of cats. Elizabethan collars (E-collars) which prevented grooming were fitted on nine cats in a flea-infested household and 3 weeks later, flea n...

Predators of herbivorous insects play important roles in tropical ecosystemsasherbivorymayaffect structure and diversity of plant populations. Although insectivorous bats are particularly abundant and diverse in the tropics, their impact on herbivorous insects is little understood. To assess prey consumption, we observed the gleaning bat Micronycteris microtis (Phyllostomidae) continuously for ...

Objectives: Self-assessment, as one type of alternative assessment, with the increased attention to learner-centered curricula, needs analysis, and learner autonomy has gained popularity in recent years. The aim of this study was to investigate the effect of self-assessment on Javanroodian Foreign Language (Kordestan) Learners’ Oral Performance ability. Methods: The assessment program ...

Background: Despite the decisive role of nurses in patient’s education, they have limited ability to carry out this responsibility. One of the reasons for this incompetence is insufficient nursing education programs. This study aimed to compare and contrast the effects of multiple teaching methods and conventional methods on knowledge, satisfaction, and performance of bachelorette nursing stude...

Questioning practice constitutes one of the typical and fundamental interactional tools in L2 teaching. Much L2 research on teacher questions has been quantitative studies focusing on identifying question types and their roles in language acquisition and meaning negotiation. However, by drawing on conversation analysis within a sociocultural perspective, this study examines qualitatively how EF...
