چکیده

To determine the factors having greatest impact on risk of occurrence water hammers in above-ground installation pipelines, typical permafrost areas. Determine velocities shock wave front propagation steel pipes for different types pipes. calculate parameters possible hammer depending pipeline wall thickness. Methods: Method characteristics used solution differential equations unsteady motion liquid is basis calculation model determination flow at hammer. Results: On calculations carried out article diagrams pressure changes made are analysed. The influence speed and steady movement a character an process size laying estimated. use measures to prevent hammers, including combined ones, with purpose increasing their reliability much cheaper than replacement damaged equipment, elimination washouts by leaking loss drinking water. Practical significance: In conditions, many complicate construction operation hydrotransport systems. Elimination consequences emergency situations accompanied leakage difficult harsh climatic thermal soils not always avoidable. Therefore when designing new systems reconstructing existing ones it necessary take into account processes

High Throughput Determination of Plant Height, Ground Cover, and Above-Ground Biomass in Wheat with LiDAR

Crop improvement efforts are targeting increased above-ground biomass and radiation-use efficiency as drivers for greater yield. Early ground cover and canopy height contribute to biomass production, but manual measurements of these traits, and in particular above-ground biomass, are slow and labor-intensive, more so when made at multiple developmental stages. These constraints limit the abilit...

Remote Sensing of Above-Ground Biomass

Accurate measurement and mapping of biomass is a critical component of carbon stock quantification, climate change impact assessment, suitability and location of bio-energy processing plants, assessing fuel for forest fires, and assessing merchandisable timber. While above-ground biomass includes both live and dead plant material, most of the recent research effort on biomass estimation has foc...

Below-ground plant–fungus network topology is not congruent with above-ground plant–animal network topology

In nature, plants and their pollinating and/or seed-dispersing animals form complex interaction networks. The commonly observed pattern of links between specialists and generalists in these networks has been predicted to promote species coexistence. Plants also build highly species-rich mutualistic networks below ground with root-associated fungi, and the structure of these plant-fungus network...
