Effects of Injection Rate Profile on Combustion Process and Emissions in a Diesel Engine

Journal of Combustion, 2017
When multi-injection is implemented in diesel engine via high pressure common rail injection system, changed interval between injection pulses can induce variation of injection rate profile for sequential injection pulse, though other control parameters ...

Research Review: Omega‐3 supplementation to reduce antisocial behavior – a systematic review and meta‐analysis of randomized controlled trials

Journal of Child Psychology and Psychiatry, EarlyView.
Background Omega‐3, a long‐chain fatty acid critical for brain structure and function, has been argued to be effective in reducing antisocial behavior, but findings are variable. This meta‐analysis examines 25 randomized controlled trials (RCTs) with a total of 2,889 participants. Methods This study was registered with PROSPERO (CRD42021256959).

Investigation of ethanol blending on soot particle evolution in counterflow diffusion flames of a gasoline surrogate

Applications in Energy and Combustion Science
Across all transport sectors, there is an increasing recognition of the importance of reducing not only CO2 emissions but also other climate-impacting pollutants, such as soot particulate matter.

Silene, a versatile model system: from sex and genome evolution to ecology and speciation

New Phytologist, EarlyView.
Summary Fundamental and applied research in evolutionary biology benefits from the use of model systems in which approaches from disparate disciplines can be integrated. Here, we review recent progress in evolutionary research on the long‐standing model system Silene, a large genus with a well‐resolved phylogeny and newly available, expanded genomic ...

Synoptic Control of Contrail Cirrus Life Cycles and Their Modification Due to Reduced Soot Number Emissions

, 2017
The atmospheric state, aircraft emissions, and engine properties determine formation and initial properties of contrails. The synoptic situation controls microphysical and dynamical processes and causes a wide variability of contrail cirrus life cycles ...

A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

Plant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

Effects on of Blended Biodiesel and Heavy Oil on Engine Combustion and Black Carbon Emissions of a Low-Speed Two-Stroke Engine

Polish Maritime Research
The effects of heavy fuel oil and biodiesel blends on engine combustion and emissions were studied in a marine two-stroke diesel engine. The engine was operated under propeller conditions using five different fuels with biodiesel blends of 10% (B10), 30%

Reduced contrail radiative effect for fleets with low soot and water vapour emissions

Atmospheric Environment: X
Besides the goal of net-zero carbon dioxide (CO2) emissions, reducing aviation’s climate impact also involves addressing other forcing effects, particularly radiative forcing from contrails.

Stratospheric aerosol modification by supersonic transport operations with climate implications [PDF]

The potential effects on stratospheric aerosois of supersonic transport emissions of sulfur dioxide gas and submicron size soot granules are estimated. An interactive particle-gas model of the stratospheric aerosol is used to compute particle changes due
