Gaseous emissions from swine (Sus scrofa) manure storage systems represent a concern to air quality due to the potential effects of hydrogen sulfide, ammonia, methane, and volatile organic compounds on environmental quality and human health. The lack of knowledge concerning functional aspects of swine manure management systems has been a major obstacle in the development and optimization of emi...

The aim of this paper is to explore methane emissions from China’s fossil fuel industry compared with the USA and Canada, a focus on emission mechanisms, calculation methods, mitigation potential, abatement technologies. This explores natural gas comparative perspective. main conclusions are as follows: (1) production phase largest in whole supply chain. (2) When it comes measurement estimation...

OBJECTIVE Due to the threat of global warming, the livestock industry is increasingly interested in exploring how feed additives may reduce anthropogenic greenhouse gas emissions, especially from ruminants. This study investigated the effect of Rhodophyta supplemented bovine diets on in vitro rumen fermentation and rumen microbial diversity. METHODS Cannulated Holstein cows were used as rumen...

Learners sometimes have incoherent and fragmented intuitive prior knowledge that is (partly) "incompatible" with the to-be-learned contents. Such knowledge in pieces can cause conceptual disorientation and cognitive overload while learning. We hypothesized that a pre-training intervention providing a generalized schema as a structuring framework for such knowledge in pieces would support (re)or...

PURPOSE The purpose of this study is to investigate the pursuit of achievement goals in medical students and to assess the relationship between achievement goals, learning strategy, and motivation. METHODS Two hundred seventy freshman and sophomore premedical students and sophomore medical school students participated in this study, which used the Achievement Goals Scale and the Self-Regulate...

The objective of this study was to understand the effects of fumarate addition on methane (CH4) and VFA production in the rumen through a meta-analysis of its effects on ruminal batch cultures. Because the reduction of fumarate to succinate can draw electrons away from ruminal methanogenesis, fumarate has been studied as a potential feed additive to decrease CH4 production in ruminants. The ave...

Meeting the projected 50% increase in global grain demand by 2030 without further environmental degradation poses a major challenge for agricultural production. Because surface ozone (O3 ) has a significant negative impact on crop yields, one way to increase future production is to reduce O3 -induced agricultural losses. We present two strategies whereby O3 damage to crops may be reduced. We fi...

The environmental targets of the recently agreed Baltic Sea Action Plan (BSAP) targets are likely associated with a considerable cost, which motivates a search for low-cost policies. The following review shows there is a substantial literature on cost-efficient nutrient reduction strategies, including suggestions regarding low-cost abatement, but actual policies at international and national sc...

Australia’s greenhouse gas emissions from agriculture in 2022 were 67.8 million (M) tonnes (t) of carbon dioxide equivalent (CO<sub>2</sub>-e), amounting to 12.9% total emissions. Erupted methane (CH<sub>4</sub>) ruminant animals comprised 42% agricultural By 2030, the Australian Government aims reduce by 43% 2005 level. The primary policy instrument for achieving this r...
