Climate Effects on Tallgrass Prairie Responses to Continuous and Rotational Grazing
Agronomy, 2019 Cattle grazing is an important economic activity in the tallgrass prairie systems in the Great Plains of the United States. Tallgrass prairie may respond differently to grazing management (e.g., high and low grazing intensity) under variable climate ...

Cow and Calf Performance as Affected by Grazing Management [PDF]
, 2004 Different grazing treatments cause changes in the quantity of plant growth and the quality of herbage; this study compares cow and calf accumulated weight gain, rate of weight gain per acre, and rate of weight gain per day on various pasture-forage types

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective
Advanced Electronic Materials, EarlyView.Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.

Smart Exploration of Perovskite Photovoltaics: From AI Driven Discovery to Autonomous Laboratories
Advanced Energy Materials, EarlyView.In this review, we summarize the fundamentals of AI in automated materials science, and review AI applications in perovskite solar cells. Then, we sum up recent progress in AI‐guided manufacturing optimization, and highlight AI‐driven high‐throughput and autonomous laboratories.

Advanced Energy Materials, EarlyView.A novel top‐to‐bottom film restructuring strategy is applied to perovskite films, taking advantage of high penetration of vapor‐phase ligand. A gradient‐distributed 2D perovskite structure is built up from top surface to film bulk, meanwhile, inhomogeneity at the buried interface is mitigated, which leads to high quality perovskite films with improved ...

The ecological effects of grazing by the White Rhino (Ceratotherium simum simum) at a landscape scale [PDF]
, 2005 In this thesis I generated hypotheses concerning the top down effect of grazing ungulates on grass communities and fire behavior from work done within grazing exclosures in Hluhluwe iMfolozi Park.

Effects of grazing and mowing on ground-dwelling predatory arthropods in a semi-arid grassland
Ecological IndicatorsThe arthropod communities are important component in grassland ecosystems and are largely affected by management. However, the information on the effects of different grassland management on ground-dwelling predatory arthropods are very limited ...

PROPERTY RIGHTS, GRAZING PERMITS, AND RANCHER WELFARE [PDF]
This study attempts to link factors affecting the demand for Bureau of Land Management grazing to perceived changes in permittee welfare over the 1962-92 period. Annual demand for federal forage is found to be sensitive to active preference, beef cow and

Advanced Energy Materials, EarlyView.Adopting a scalable hybrid two‐step deposition process route, textured perovskite/silicon tandem solar cells achieve over 30% power‐conversion efficiency. The process route replaces all non‐scalable spin‐coating steps, including organic precursor deposition, self‐assembled monolayer formation, and passivation layer deposition, with scalable techniques ...

Understanding the effects of cattle grazing in English chalk streams
, 2012 Accounting for much of the landscape of southern England, chalk stream environments hold significant cultural, economic and ecological value. However, attempts to retain this value are often hindered by the remnants of historic management practices that ...
