Minimal impact of spotted hyenas on livestock and endangered species in a prey‐rich ecosystem
Wildlife Biology, EarlyView.The diet of large carnivores is of great interest to conservation managers, as it can reveal the extent of human–carnivore conflict and the impact of carnivores on species of high conservation priority. Metabarcoding of environmental DNA can identify species and is often more reliable than observational or morphological methods, particularly when it ...

Ideas for Testing of Planetary Gear Sets of Automotive Transmissions
Journal of Middle European Construction and Design of Cars, 2017 Abstract The article describes the concept of modular stand, where is possible to provide tests of gear pairs with fixed axes from mechanical automotive gearboxes, as well as tests of separate planetary sets from automatic gearboxes. Special attention in the article will be paid to the variant dedicated for testing of planetary gear sets.

International Journal of Urban and Regional Research, EarlyView.Abstract The Beqaa Valley in Lebanon has become increasingly polluted, and residents are attributing illness to improper waste disposal and dumping. This article explores local epistemologies of pollution’s causes and effects in three films, which were researched and produced by local residents of Bar Elias, a small town in the Beqaa, which has rapidly

Loader power-split transmission system based on a planetary gear set
Advances in Mechanical Engineering, 2018 In hydraulic mechanical transmission loaders, a hydraulic torque converter can prevent an engine from stalling due to overloading of the loader during the spading process; however, the hydraulic torque converter also reduces the loader’s fuel economy ...

AGRICULTURE IN A SOCIALIST CITY: Towards an Alter‐Urban Political Ecology
International Journal of Urban and Regional Research, EarlyView.Abstract Urban political ecology has developed as a critique of capitalist urbanization. This article develops the concept of alter‐urban political ecology to define urban environments emerging not from capitalist urbanization but from efforts to transform it. Drawing on archival research and ethnographic fieldwork in five urban farms in socialist Cuba,
