Enhancement of combustion effect leading to improved performance and exhaust emissions of an SI engine with ferrous oxide and graphite nanoparticles
Environ Sci Pollut Res Int. 2023 Aug 8. doi: 10.1007/s11356-023-28556-z. Online ahead of print.ABSTRACTThe present study was conducted to investigate the effectiveness of new, less toxic, less harmful, and nonmetallic graphite (G) and metallic iron oxide (Fe2O3) nanofuel additives by analyzing experimentally their consequences on exhaust emissions and performance of an air cooled, single cylinder, 4-stroke gasoline engine. Fe2O3 and graphite nanoparticles at 40, 80, and 120 mg/l of gasoline concentrations were mixed with gasoline by means of a magnetic stirrer. Brake power (BP), brake-specific fuel consumption (BSFC), torq...

A New Study Shows How Seriously Air Pollution Can Affect Your Heartbeat
For China’s 1.4 billion people, the simple act of breathing has long been something of a risk. Living in the ninth-dirtiest country in the world in terms of air quality, China’s residents lose an average of 2.6 years of life per capita due to atmospheric pollution alone. The greatest risk, of course, is pulmonary, with air pollution leading to shortness of breath, wheezing, coughing, asthma episodes, and chest pain. But pollution affects the heart too; the U.S. Environmental Protection Agency reports that exposure to fine-particulate matter as well as to nitrogen oxides alone can lead to premature aging in bloo...

Study the effects of dimethyl carbonate as a fuel cetane improver on diesel engine emissions
AbstractIn this work, diesel engine emissions are studied by adding a cetane improver to the engine fuel. Dimethyl carbonate (DMC) additive is used as a cetane improver. A single-cylinder, four-stroke diesel engine is used to test the fuels. Three fuels are selected to run the engine, namely, biodiesel derived from neem oil  + 1 vol% DMC (BD100 + 1DMC), BD100, and diesel. BD100 + 1DMC fuel emits a reduced amount of carbon monoxide and unburnt hydrocarbons compared to diesel under the same operating conditions of engine. The level of nitrogen oxides emission for BD100 + 1DMC is slightly higher compared to diese l a...

Air Pollution and Arrhythmias
Can J Cardiol. 2023 Apr 4:S0828-282X(23)00293-3. doi: 10.1016/j.cjca.2023.03.023. Online ahead of print.ABSTRACTAir pollution is commonly defined as the contamination of the air we breathe by any chemical, physical or biological agent that is potentially threatening to human and ecosystem health. The common pollutants known to be disease-causing are particulate matter, ground-level ozone, sulphur dioxide, nitrogen dioxide and carbon monoxide. Although the association between increasing concentrations of these pollutants and cardiovascular disease is now accepted, the association of air pollution and arrhythmias is less wel...

Evidence of clinical efficacy and pharmacological mechanism of N-butylphthalide in the treatment of delayed encephalopathy after acute carbon monoxide poisoning
CONCLUSION: The NMA screened for regimens with better efficacy for each outcome indicator in order to provide a reference for clinical treatment. NBP can stably bind ALB, ESR1, EGFR, HSP90AA1, and other targets, and may play a role in neuroprotection for patients with DEACMP by modulating Lipid and atherosclerosis, IL-17 signaling pathway, MAPK signaling pathway, FoxO signaling pathway, PI3K/AKT signaling pathway.PMID:37006490 | PMC:PMC10060646 | DOI:10.3389/fneur.2023.1119871

Cardiac stroke volume in females and its correlation to blood volume and cardiac dimensions
In conclusion, the SV strongly correlates with the cardiac dimensions, which might be the result of adaptations to an increased volume load. The positive effect of a high BV on SV is particularly noticeable at high and severe intensity exercise. The theoretically expected reduction in V̇O2max due to lower SV as a consequence of reduced BV is apparently compensated by the increased arterial oxygen content due to a higher [Hb].

Air pollution and headache disorders
Divyani Garg, Man Mohan Mehndiratta, Mohammad Wasay, Vasundhara AggarwalAnnals of Indian Academy of Neurology 2022 25(7):35-40 Air pollution, the most prevalent form of pollution worldwide, is associated with a wide range of neurological disorders, including neurodegenerative conditions, stroke, autism, depression, and developmental delay. There is accumulating evidence on the association between air pollution and headache disorders, especially migraine. Many classical and non-classical air pollutants have been associated with headache, including particulate matter, nitrogen dioxide, sulfur dioxide, ozone, carbon monoxide...

Experimental investigation on sucrose/alumina catalyst coated converter in gasoline engine exhaust gas
In this study, a modified catalytic converter was employed to treat the harmful exhaust gas pollutants of a twin-cylinder, four-stroke spark-ignition engine. This research mainly focuses on the emission reduction of unburnt hydrocarbons, carbon monoxide, and nitrogen oxides at low light-off temperatures. A sucrolite catalyst (sucrolite) was coated over the metallic substrate present inside the catalytic converter, and exhaust gas was allowed to pass through it. A scanning electron microscope, X-ray diffraction, and Fourier transform infrared spectroscopy were used to investigate the changes in morphology, chemical compound...
