Snow is a highly porous material with properties that may strongly differ depending on the environmental conditions.On slopes, the layered snowpack may fail and avalanches occur.Hence, knowing how snow deforms and fails is essential for understanding and modeling snow avalanche release and flow.The response of snow to imposed load or deformation an

Multispectral imaging (MSI) has become a new fast and non-destructive detection method in seed Analysis of the use of fenthion via epicutaneous in dogs for Rhipicephalus sanguineus control Análise do uso de fenthion via epicutânea em cães para o controle de Rhipicephalus sanguineus identification.Previous research has usually focused on single m

This study designed a vertical take-off and landing tailsitter unmanned aerial vehicle (UAV) with a long endurance time.Nine parameters of the tailsitter UAV were investigated.Using a 2k full factorial test, 512 experiments on the nine parameters were conducted at their maximum and minimum values.The time coefficient and air resistance were calcula

The conceptual design Study on Illumination Intensity and Duration of LED Light Sources for a Weaned Piglet House without Natural Light of a hybrid aerial vehicle for the exploration of the upper Venus atmosphere is presented.The vehicle will float like a balloon and harvest solar energy which is stored in batteries.The neutral buoyancy reduces the
