Energy and water availability were identified as the first order controls of evapotranspiration(ET) in ecohyrodrology. With a ~1,000 km precipitation gradient and distinct wet-dry climate,the North Australian Tropical Transect (NATT) was well suited for evaluating how energy andwater availabilities constrain water use by vegetation, but has not been done yet. In this study,we addressed this que...

BACKGROUND The study investigated the perspective of people with mobility limitations (PWML) in Zambia, firstly of their accessibility to public buildings and spaces, and secondly of how their capacity to participate in a preferred lifestyle has been affected. OBJECTIVES Firstly to provide insight into the participation experiences of PWML in the social, cultural, economic, political and civi...

BACKGROUND Mobility-related fatigue and low socioeconomic position predicts mobility limitations and disability in old age, but the interplay between these two factors is unknown. To evaluate whether mobility-related fatigue is a stronger risk factor for mobility limitations in certain socioeconomic groups, the aim of this study was to examine the combined effect of mobility-related fatigue and...

We evaluate whether trends in the prevalence of disability among the aged can be investigated using the 1980 U.S. Census' public transportation question and the 1990 query on mobility limitation. Despite the obvious difference in the two questions, we found remarkable similarity in major cross-sectional patterns, such as those by age and sex, when comparing results from the two data sets. This ...

Photosynthesis produces chemical energy from photon energy in the photosynthetic electron transport and assimilates CO2 using the chemical energy. Thus, CO2 limitation causes an accumulation of excess energy, resulting in reactive oxygen species (ROS) which can cause oxidative damage to cells. O2 can be used as an alternative energy sink when oxygenic phototrophs are exposed to high light. Here...

The purpose of this study was to investigate what older adults with severe, moderate, or no mobility limitation consider motives for and barriers to engaging in physical exercise. Community-dwelling adults (N=645) age 75-81 years completed a questionnaire about their motives for and barriers to physical exercise and answered interview questions on mobility limitation. Those with severely limite...
