Review of black carbon emission factors from different anthropogenic sources

Environmental Research Letters, 2023
Particulate black carbon (BC) affects global warming by absorbing the solar radiation, by affecting cloud formation, and by decreasing ground albedo when deposited to snow or ice.

Greenhouse gas emissions during the COVID-19 pandemic from agriculture in China [PDF]

Frontiers of Agricultural Science and Engineering
● Methane led China’s growth in net greenhouse gas emissions over the pandemic. ● N2O was linked to fertilizers and waste management. ● CO2 emissions varied by region, calling for tailored mitigation approaches.

Bottom-Up Emission Inventory and Its Spatio-Temporal Distribution from Paved Road Dust Based on Field Investigation: A Case Study of Harbin, Northeast China

Atmosphere, 2021
Road dust is one of the primary sources of particulate matter which has implications for air quality, climate and health. With the aim of characterizing the emissions, in this study, a bottom-up approach of county level emission inventory from paved road

Emission Levels and Emission Factors for Modern Wood Stoves

Chemical Engineering Transactions, 2023
The aim of this work is to recommend more correct emission factors for the modern wood stove category, based on extensive measurements carried out at SINTEF Energy Research in Norway for representative modern wood stoves. Today the best wood stoves outperform the staged air combustion wood stoves introduced in the 1990s, as further continuous ...

Measuring Organic Molecular Emission in Disks with Low Resolution Spitzer Spectroscopy

, 2011
We explore the extent to which Spitzer IRS spectra taken at low spectral resolution can be used in quantitative studies of organic molecular emission from disks surrounding low mass young stars.

Generalized Emission Functions for Photon Emission from Quark-Gluon Plasma [PDF]

, 2006
The Landau-Pomeranchuk-Migdal effects on photon emission from the quark gluon plasma have been studied as a function of photon mass, at a fixed temperature of the plasma. The integral equations for the transverse vector function (${\bf \tilde{f}(\tilde{p}

Estimation of N2O emission factors for soils depending on environmental conditions and crop management [PDF]

, 2009
Nitrous oxide (N2O) contributes 8% to anthropogenic global warming, of which about one third are direct emissions of agricultural soils. These N2O emissions are often estimated using the default IPCC 2006 emission factor of 1% of the amount of N applied ...

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Rest-frame UV line emission from the intergalactic medium at 2

, 2011
Rest-frame UV emission lines offer the possibility to directly image the gas around high-redshift galaxies with upcoming optical instruments. We use a suite of large, hydrodynamical simulations to predict the nature and detectability of emission lines ...
