Wind erosion of soil is an appreciable but unstudied event following fires in cold desert. We examined aeolian transport of sediment for one year following fire in semiarid shrub steppe of southern Idaho. Sediment collectors were used to determine horizontal mass transport of soil ( ) and saltation sensors and anemometers were used to determine saltation activity (# seconds saltation is detecte...

<p>This research examines the scope for reducing air pollution caused by transportation sector through infusion of biofuel and antioxidants ensuring partial replacement conventional fuel. A four-stroke, direct-injection, multi-cylinder constant-speed diesel engine was employed experimental analysis. The ternary fuel blend with a composition 70% fuel, 20% rubber seed oil 10% pentanol sea w...

Background The Nechako River Basin (NRB) is a large, regulated basin in north-central British Columbia, Canada that has been impacted by numerous landscape disturbances, including severe wildfire 2018. Aims aims of this study were to quantify the post-wildfire temporal and spatial extent contamination polycyclic aromatic hydrocarbons (PAHs) both soils riverine sediments, identify primary source...

Inventories of fire-derived (pyrogenic) C (PyC) stocks in soils remain incomplete for many parts of the world, yet are critical to reduce uncertainties in global PyC estimates. Additionally, PyC dynamics in soils remain poorly understood. For example, dissolved PyC (DPyC) fluxes from soil horizons, as well as the influence of historical fire events on these fluxes and soil PyC stocks remain poo...

This research/article aimed to analyze the influence of an after-treatment system (ATS) on emissions a heavy-duty spark-ignition (HD-SI) engine fueled with liquified petroleum gas (LPG), in context current Euro VI requirements. The ATS is composed by three-way catalyst (TWC) series diesel particle filter (DPF). Emissions testing were carried out test bench according homologation procedures, per...

Use of biodiesel as an alternative to diesel could reduce the dependency on petroleum products and the pollution problem. The physical properties of the fuel such as viscosity, volatility and f lash point also affect the combustion process, thereby engine performance. Specif ically atomization of the fuel during the injection is attributed to higher viscosity of biodiesel. Injec ted fuel drople...

The current study investigates the opportunity of using olive mill wastewater (OMWW) as a renewable fuel in internal combustion engines. biofuel was made from hydrothermal conversion OMWW sub-/supercritical alcohol-water system. blended with pure diesel (designated B0). Three blends namely B10, B20 and B30 containing respectively 10%, 20% 30% by volume were tested. This paper focuses on experim...

—Widespread establishment of seedling aspen (Populus tremuloides) occurred in Yellowstone National Park (YNP) following the extensive1988 fires. Aspen stands occupy ;2% of YNP and aspen stems are intensively browsed by native ungulates. Chemical composition, especially secondary compounds, may influence levels of herbivory and, hence, survival of aspen, but concentrations of such compounds in a...

In this study, catalyst of rutile titanium dioxide nanoparticles (rTiO2-NP) has been investigated for the removal and reduction of unburned hydrocarbons as benzopyran. To evaluate and calculate the thermodynamic properties of this aim, pollutants are closed to the nanoparticles and converted them into other products and the carbon dioxide molecules are simulated in the 12th steps. The geometric...
