Usability of volatile organic compounds from exhaled breath compared with those from ruminal fluid, serum, urine, and milk to identify diet-specific metabolite profiles in lactating dairy cows

Journal of Dairy Science
: To investigate dietary influences on the volatilome, the volatile subcategory of the metabolome, we performed a comparative untargeted volatilome analysis of exhaled breath, ruminal fluid, serum, urine, and milk from lactating Holstein cows fed ...

Accounting for spatiotemporally correlated errors in wind speed for remote surveys of methane emissions [PDF]

Atmospheric Measurement Techniques
Spatiotemporally correlated errors in wind speeds estimated via numerical weather prediction (NWP) models – where estimated wind speeds and associated uncertainties at similar times or at nearby sites are likely to be correlated – are an important, but ...

Analysis of Heating System Impacts on Battery Electric Vehicle Operation at Cold Temperatures

World Electric Vehicle Journal
This paper presents the results from in-lab chassis dynamometer testing of two battery electric vehicles of the same make and model: a 2022 model year vehicle with a heat pump and a 2020 model year vehicle with a resistive positive temperature ...

A review of methane emissions source types, characteristics, rates, and mitigation effectiveness across U.S. and Canadian cities

Environmental Research Letters
Cities are major aggregated sources of methane (CH _4 ) emissions and can therefore play a role in mitigating climate warming. However, diverse, spatially distributed sources make characterizing urban CH _4 emissions challenging.

Parametric study of the decomposition of methane for COx-free H2 and high valued carbon using Ni-based catalyst via machine-learning simulation

Green Energy and Resources
With industrial informatization, abundant data provides solutions for the digital design of methane-based hydrogen production. Catalytic methane decomposition (CMD) is a promising strategy for COx-free hydrogen production, with high-value carbon products

Three-dimensional imaging to estimate in vivo body and carcass chemical composition of growing beef-on-dairy crossbred bulls

Animal
The dynamics of cattle body chemical composition during growth and fattening periods determine animal performance and beef carcass quality. The aim of this study was to estimate the empty body (EB) and carcass chemical composition of growing beef-on ...

Fortifying casein phosphopeptides and Ca in wheat reduces the As, Cd, and Pb bioavailability based on a mouse model: Calcium and phosphate transporters and gut microbiota

Soil & Environmental Health
Reducing the oral bioavailability of metal contaminants including As, Cd, and Pb in foods can protect human health. Studies showed reduced metal bioavailability with elevated Ca and Fe intake; however, the effectiveness of enhancing food Ca and Fe ...
