Carbon sequestration in soils might mitigate the increase of carbon dioxide (CO2) in the atmosphere. Two contrasting subtropical perennial forage species, bahiagrass (BG; Paspalum notatum Flügge; C4), and rhizoma perennial peanut (PP; Arachis glabrata Benth.; C3 legume), were grown at Gainesville, Florida, in field soil plots in four temperature zones of four temperature-gradient greenhouses, t...

carbon dioxide (co2) concentration of the global atmosphere has increased during the last decades. increasing global atmospheric co2 concentrations are expected to influence crop production. in order to evolution of co2 concentration effects on morphophysiologycal traits in tagets, ageratum and gauilardia, a factorial experiment based on completely randomized design with 3 replications and 12 t...

Carbon dioxide (CO2) enrichment of anaerobic digesters (AD) was previously identified as a potential on-site carbon revalorisation strategy. This study addresses the lack of studies investigating this concept in up-scaled units and the need to understand the mechanisms of exogenous CO2 utilisation. Two pilot-scale ADs treating food waste were monitored for 225 days, with the test unit being per...

BACKGROUND Cardiopulmonary exercise testing (CPET) variables provide valuable prognostic information in the heart failure (HF) population. The purpose of the present study is to assess the ability of resting end-tidal carbon dioxide partial pressure (PETCO2) to predict cardiac-related events in patients with HF. METHODS 121 subjects diagnosed with compensated HF underwent CPET on an outpatien...

Introduction: Greenhouse gas (GHG) emissions have caused environmental effects. Food production is one of the sources of GHGs. This study aimed to suggest dietary scenarios for decreasing GHG emissions. Materials and Methods: GHG emissions in the target population of Urmia city, Northwest Iran, were investigated using a modeling approach. Three dietary scenarios were modeled and analyzed to ev...

Increasing level of carbon dioxide CO2 due to industrial activity is primarily cause of global warming. Planting Artoplex lentiformis can help to reduce atmospheric CO2 buildup partly replacing use of fuels and by carbon storage. The objective of this study was to determine the effects of row spacing on carbon storage. A split- plot design with three replications included three row spacing (2×2...

Tomato production under tunnel structures has shown promising returns in recent years Pakistan. However, the energy use and GHGs dynamics remain largely unknown for tomato controlled conditions. This study estimates budgeting GHG emission off-season (tunnel-farming) production. Study data were gathered from 70 growers through a simple random sampling technique. Energy efficiency, productivity, ...
