Age-structure analysis of aspen (Populus tremuloides) was conducted on Rocky Mountain elk (Cervus elaphus) winter range in the northern Yellowstone area by collecting increment cores from aspen trees in Yellowstone National Park, the Gallatin National Forest, and the Sunlight/Crandall area of the Shoshone National Forest. Our goal was to compare aspen age structure for elk winter range in the p...

We examined bird-habitat relationships within and across a range of aspen habitats in four major watersheds in the eastern Sierra Nevada mountains of California and Nevada to identify habitat features of importance to aspen-breeding birds. Using point counts and vegetation assessments from 462 individual stations between 2001 and 2003 allowed us to investigate important habitat features at wate...

Motivation The application of a genomics assay to samples from a cohort is a frequently applied experimental design in cancer genomics studies. The collection and analysis of cancer sequencing data in the clinical setting is an elaborate process that may involve consenting patients, obtaining possibly-multiple DNA samples, sequencing and analysis. Many of these steps are manual. At any stage mi...

Global interest in LNG products and supply chains is growing, demand continues to rise. As a clean energy source, can nevertheless emit air pollutants, albeit at lower level than transitional sources. An plant capable of producing up 126 MMTA was successfully developed simulated this study. A hybrid life cycle assessment model examine the social human health impacts chain’s environmental emissi...

In response, Department of Chemical Engineering (DIQ) at University Magallanes sought alternative strategies for remote teaching. This article reports on their experience delivering technical process simulation skills final-year undergraduate ch...

During petroleum industry operations, burning flammable gas components in the flaring stacks is common, normally a symbol for stable production, but these creates harmful emissions environment. This has with high quantity of heating power, an important measurement that quantifies energy can potentially be obtained from this wasted resource. paper aims to evaluate usage gas, estimating possible ...

Solar power generation has emerged as one of the most rapidly growing sources renewable energy. The solar thermal system with a Rankine cycle used to harness energy and generate electricity from low temperature heat source is an emerging technology. major drawback its poor efficiency, which around 10% 15%. Although prior attempts improve efficiency use Nano fluids in transfer applications have ...

Natural gas is a promising elective source of methane (CH4) due to its accessibility and renewability. However, unfortunately, high rate carbon dioxide (CO2) very little hydrogen sulfide (H2S) found in this CH4 source. These compounds must be removed get natural satisfactory quality. One the most modern common strategies synchronous CO2 and...

Aspen has been an ecologically important, though relatively minor, component of the Lake States (Michigan, Wisconsin, and Minnesota) forests for millennia. General Land Office records from the 1800s indicate that aspen comprised a small fraction of the region’s eastern forests, but was more extensive on the western edge. Then Euro-American settlement in the 1800s brought land clearing, timber h...

The Central Plains of Western Canada comprise the Prairies Ecozone and the Boreal Plains Ecozone. The former has the most grasslands and is divided into seven ecoregions: Mixed Grassland, Cypress Upland, Moist Mixed Grassland, and Fescue Grassland in southern Alberta and Saskatchewan; Aspen Parkland, which extends in an arc from central Alberta and Saskatchewan southeast to southwestern Manitob...
