The effect of peat structure on the spatial distribution of biogenic gases within bogs: EFFECT OF PEAT STRUCTURE ON BIOGENIC GAS
(Wiley, 2014-10-30)Northern peatlands are a large source of atmospheric methane (CH4) and both a source and a sink of atmospheric carbon dioxide (CO2). The rate and temporal variability in gas exchanges with peat soils is directly related ... -
Effect of Plant Functional Type on Methane Dynamics in a Restored Minerotrophic Peatland
(Springer, 2017-01)Background and Aims: Peatland methane (CH4) fluxes may vary between plant types; however, in mixed communities, the specific role of each species is difficult to distinguish. The goal of this study was to determine the ... -
The effect of portable HEPA filter air cleaners on indoor PM2.5 concentrations and second hand tobacco smoke exposure among pregnant women in Ulaanbaatar, Mongolia: The UGAAR randomized controlled trial
(Elsevier, 2018-02-15)Background Portable HEPA filter air cleaners can reduce indoor fine particulate matter (PM2.5), but their use has not been adequately evaluated in high pollution settings. We assessed air cleaner effectiveness in reducing ... -
Effect of pressure and temperature on interfacial tension of poly lactic acid melt in supercritical carbon dioxide
(Elsevier, 2015-04-11)The interfacial tension of poly lactic acid (PLA) melt is measured in supercritical carbon dioxide (CO2) at the temperature range of 143 °C to 168 °C and CO2 pressures up to 2000 psi, using Axisymmetric Drop Shape Analysis ... -
Effect of Pt loading and catalyst type on the pore structure of porous electrodes in polymer electrolyte membrane (PEM) fuel cells
(Elsevier, 2018-05-01)Catalyst layer (CL) has a significant impact on the overall pore structure of the entire electrodes, thereby impacting the transport processes and the performance of polymer electrolyte membrane (PEM) fuel cells. In this ... -
The effect of pure aluminum cold spray coating on corrosion and corrosion fatigue of magnesium (3% Al-1% Zn) extrusion
(Elsevier, 2017-01-15)Pure aluminum powder was successfully sprayed on AZ31B extrusion flat and round coupons at low temperature. The corrosion and corrosion fatigue behavior of the coated and uncoated samples were examined by performing ... -
Effect of quality control parameter variations on the fatigue performance of aluminum friction stir welded joints
(Elsevier, 2019-01-01)This paper describes fatigue tests performed on 6061-T651 and 5083-H321 aluminum friction stir welded joints with dimensions and loading conditions typical for structural applications. Butt and lap joint details with various ... -
The effect of soil moisture and oxygen content on naphthalene biodegradation
(Global Water Futures, 2023-05-15)Petroleum hydrocarbon (PHC) contamination of soil and groundwater is a serious threat to ecosystems and natural resources worldwide. Biodegradation is a key process contributing to the natural attenuation and remediation ... -
Effect of Temperature and Pressure on Surface Tension of Polystyrene in Supercritical Carbon Dioxide
(ACS Publications, 2007-02-15)The surface tension of polymers in a supercritical fluid is one of the most important physicochemical parameters in many engineering processes, such as microcellular foaming where the surface tension between a polymer melt ... -
The effect of transcranial direct current stimulation on contrast sensitivity and visual evoked potential amplitude in adults with amblyopia
(Springer Nature, 2016-01-14)Amblyopia is a neurodevelopmental disorder of vision that occurs when the visual cortex receives decorrelated inputs from the two eyes during an early critical period of development. Amblyopic eyes are subject to suppression ... -
The effect of type of afferent feedback timed with motor imagery on the induction of cortical plasticity
(Elsevier, 2017-11-01)A peripherally generated afferent volley that arrives at the peak negative (PN) phase during the movement related cortical potential (MRCP) induces significant plasticity at the cortical level in healthy individuals and ... -
Effect of water table drawdown on northern peatland methane dynamics: Implications for climate change
(Wiley, 2004-10-07)As natural sources of methane (CH4), peatlands play an important role in the global carbon cycle. Climate models predict that evapotranspiration will increase under a 2 x CO2 scenario due to increased temperatures leading ... -
