A significant part of thermal energy is lost precisely during its transportation.By increasing the efficiency of thermal insulation of pipelines, it is possible to reduce significantly heat loss around the world.The purpose of the paper is to develop and validate methods for increasing the efficiency of thermal insulation of pipelines by determinin
In order to make clear the mechanism of oil churning loss of gearbox and to further improve the efficiency of gear transmission,the factors that effects on oil churning losses are studied.The finite element model of oil fluid in gearbox is established in terms of the condition of the gear transmission under oil-immersed lubrication.The variation of
Riau Province is one of the prone areas of forest and land fires in Indonesia.Fires began to grow since the 1980s as deforestation and the clearing of palm oil plantations occured.The peak of a major fire was happened before the study was taken from 2014 to 2015 and caused a smoke haze for months.This study aims to determine the factors causing for
Fire is a common disturbance in boreal forests causing changes in biological diversity at various spatial scales.In the past 100 years, forest management has limited fire outbreaks, but in the future, the fire-affected forest area is expected to increase in many regions due to climate change.Burned forests Skillets are typically salvage-logged, but
