Under the harsh environmental conditions present in severely overgrazed, semiarid rangelands, facilitator plants offer a promising tool for ecological restoration. This study investigated facilitative effects of Aloe secundiflora—a native drought-tolerant, unpalatable, thorny shrub—on grass establishment in degraded rangelands in Kenya. We planted native perennial grass seeds adjacent to three ...

The combined effect of urbanization and agriculture, two most pervasive land use activities, on the surface climate remains poorly understood. Using Moderate Resolution Imaging Spectroradiometer data over 2010–2015 and forests as reference, we showed that urbanization warmed the land surface temperature (LST), especially during the daytime and in growing seasons (maximized at 5.0 ± 2.0°C in May...

Abstract Although onion, Allium cepa L., production has been enhanced by the addition of organic matter to soil, other reports indicated no effect. In this study, onion plots (var. Sweet Sunrise) were treated with conventional fertilizer, composted sugar mill ash and vegetative yard waste, or fertilizer + compost. Measurements during two consecutive growing seasons in Lower Rio Grande Valley Te...

Abstract Ground-level ozone (O 3 ) pollution is a persistent environmental issue that can lead to adverse effects on trees and wood production, thus indicating need for forestry interventions mediate O effects. We treated hybrid larch ( Larix gmelinii var . japonica × L. kaempferi saplings grown in nutrient-poor soils with 0 or 400 mg L ?1 water solutions of the antiozonant ethylenediurea (EDU0...

Gas turbines incur a loss of output power during hot seasons due to high ambient air temperatures, and input air cooling systems are often used to partly offset this problem. Here, results are reported for an investigation of the utilization of a heat pump to cool the inlet air of a gas turbine compressor. The analyses are carried out for two climates: the city of Yazd, Iran, which has a hot, a...

BACKGROUND Groin injury is a common injury in football and a complicated area when it comes to diagnosis and therapy. There is a lack of comprehensive epidemiological data on groin injuries in professional football. OBJECTIVE To investigate the incidence, pattern and severity of hip and groin injuries in professional footballers over seven consecutive seasons. STUDY DESIGN Prospective cohor...
