Long term wheelchair usage has been related to a number of problems, among which pressure ulcers are one of most concern. The design of wheelchair seat cushions has been of increasing interest among researchers, as it can ...

Aim: Local effects of ecosystem engineers on biodiversity can scale up to the landscape level, stressing the importance of ecological processes as determinants of species richness at larger spatial scales. In harsh ...

Planos copia de: Exploded view & B/M chairs & ottoman - Arm panel details seating - Back panel details seating - Back cushion bracket details seating - Assembly details ( for swivel tilt w/caster version) - Assembly details ...

Ecosystem engineers are organisms able to modulate environmental forces and, hence, may change the habitat conditions for other species. In so doing, ecosystem engineers may affect both species richness and evenness of ...

•Vascular wetland plants may substantially increase methane emissions by producing root exudates and easily degradable litter, and by providing a low-resistance diffusion pathway via their aerenchyma. However, model studies ...

Several plants invade the cushions of Laretia acaulis in the high Andean communities of central Chile. Humus develops among the rosettes, and 42 different species settle on the cushions. Most of these species are also found ...

Study design: Cross-sectional study. Objectives: To evaluate the efficacy of the Postural Assessment Software PAS/SAPO in the posture analysis of individuals with spinal cord injury (SCI) during sitting position and to ...

Mosses are a dominant ground cover in a wide array of ecosystems, especially in those developing under cold-stressed environments such as arctic and alpine ice-melting glacial forelands. Consequently, mosses may influence ...

High mountain environments are highly stressful for insect survival. It has been suggested that small microtopographic variations generating less stressful microclimatic conditions than the surrounding environment would ...

In alpine habitats, positive interactions among plants tend to increase with elevation as a result of altitudinal increase in environmental harshness. However, in mountains located in arid zones, lower elevations are also ...
