Abstract:
The rapid and steady increase in the concentration of CO2, the most abundant greenhouse gas in the atmosphere, leads to extreme weather and climate events. Due to the burning of fossil fuels (oil, coal and natural gas), the concentration of CO2 in the air has been increasing in recent decades by more than 2 ppm per year, and in the last year alone - by 3.29 ppm. To prevent the "worst" scenarios of climate change, immediate and significant reductions in CO2 emissions through carbon management are needed. Aim.

In indicator-dilution experiments, recoveries of dissolved CO2 and acetylene (C2H2) in the venous effluent were delayed significantly compared with a vascular indicator because the gases were distributed in both the vascular and alveolar volumes.

Abstract:
Acute Heart Failure (AHF) can affect carbon dioxide levels in the body by altering the balance between ventilation and carbon dioxide production, leading to either hypocapnia or hypercapnia. Arterial carbon dioxide (CO2) levels are essential for maintaining respiratory function and acid-base balance. However, the relationship between arterial CO2 levels and AHF remains complex and not fully understood. Diverse factors affect arterial CO2 levels in patients with AHF, including neurohormonal activation, respiratory compensation for hypoxemia, and changes in pulmonary perfusion. Hypocapnia, chara

ABSTRACTLower Devonian volcanic rocks in the northern British Isles, especially Scotland, show extensive evidence for contemporaneous subaerial weathering. Basalt and andesite lavas were altered to red iron oxides, commonly accompanied by calcite. Measurement of carbonate contents in 104 samples over a region of 100,000 km2 show an average of 13% calcite. Weighted for outcrop thickness, this represents an estimated 7.3×1016 moles CO2, extracted from surface waters and ultimately the atmosphere. The time frame for this drawdown is difficult to constrain, but complete weathering of a one-metre u

The growing emission of carbon dioxide (CO2), combined with its ecotoxicity, is the reason for the intensification of research on the new technology of CO2 management. Currently, it is believed that it is not possible to eliminate whole CO2 emissions. However, a sustainable balance sheet is possible. The solution is technologies that use carbon dioxide as a raw material. Many of these methods are based on CO2 methanation, for example, projects such as Power-to-Gas, production of fuels, or polymers.

Land use has a very close relationship with transportation. Transportation is formed as a result of the interaction between land use and its support system. Good land use supported by good infrastructure will result in good movement as well. Accessibility is one of the supporting factors for good interaction between transportation and land use—the better the land use conditions in an area, the greater the movement in that area. However, the interaction between land use and transportation can cause one of the problems: the increase in carbon dioxide emissions due to the more significant movemen

The permanent underground storage of large quantities of anthropogenic carbon dioxide from thermal energy and industrial plant is widely recognised as a fundamental tool which can help to avoid the worst impacts of climate change. To achieve this effectiveness, it will require widespread global deployment in a new industry which would rival the current oil and gas industry in its scale and ambition. Many of the technologies for carbon dioxide storage are the adaptations of oil and gas technology, but there are some important differences. These arise from: 1. the thermodynamic properties of car

The Null Hypothesis sets sea surface temperature (SST) as the baseline driver for Cenozoic P(CO2). The crystallization and cooling of flood basalt magmas is proposed to have heated the ocean, producing the Paleocene–Eocene Thermal Maximum (PETM). Heat of fusion and heat capacity were used to calculate flood basalt magmatic Joule heating of the ocean.

Carbon dioxide (CO2) conversion is a suite of chemical and biological processes that transform the carbon in CO2 into other forms, such as mineral carbonates, alcohols, hydrocarbons, polymers, or elemental carbon materials. Such processes allow CO2 to replace fossil fuels to enable sustainable production of chemicals and materials, and support durable storage of CO2 in long‐lived products, two underexamined aspects of addressing CO2 accumulation in the atmosphere.

Over 90% of the vented CO2 from an ammonia plant was used in this scheme, CO2 was directly injected into the wastewater to neutralize it, by reducing the pH to acceptable standard (7.0). This was achieved because the CO2 produces carbonic acid (H2CO3). The use of this process produced a better overall effluent quality of wastewater (pH, 7.56; TDS, 155.15 ppm; Heavy metal, 1.49 ; ppm) as against the use of H2SO4 (pH, 8.77; TDS, 1000 ppm; Heavy metals, 2.90 ppm) which
