A Numerical Investigation of the Effects of Piston Bowl Geometry and Spray Angle on Combustion, Performance and Emission of a Diesel Engine

open access: yesEnergy Science &Engineering, EarlyView.
A piston bowl's design and spray angle improve air‐fuel mixing, resulting in more complete combustion and higher efficiency. Ansys Forte 2023 R1 a CFD software was used to analyze the effects of five combustion chamber geometries of cylinder, modified re‐entrant, re‐entrant, double‐stepped, and stepped on engine performance, combustion, and emission ...

Hydrogen‐Enriched Tri‐Fuel Combustion for Low‐Carbon Engines at Medium Engine Load: A Comprehensive CFD Analysis

open access: yesEnergy Science &Engineering, EarlyView.
CFD analysis of a diesel–CH4–H2 tri‐fuel engine shows that increasing hydrogen energy share (HES) enhances mixing and accelerates combustion, improving pressure, efficiency, and reducing CO and soot. At 60% HES, ISFC improves 26.2%, soot drops 95%, while NOx increases due to higher temperatures. ABSTRACT The global commitment to achieve net‐zero carbon

The GARP Domain of the Rod CNG Channel's β1-Subunit Contains Distinct Sites for Outer Segment Targeting and Connecting to the Photoreceptor Disk Rim

open access: yesJournal of Neuroscience, 2020
Vision begins when light is captured by the outer segment organelle of photoreceptor cells in the retina. Outer segments are modified cilia filled with hundreds of flattened disk-shaped membranes.

Variation in Stabilization and Resuscitation Practices at Birth of Preterm Infants Among 12 National or Regional Neonatal Networks

open access: yesActa Paediatrica, EarlyView.
ABSTRACT Aim Neonatal resuscitation follows national or regional guidelines, but uptake varies in clinical practice. This study aimed to examine variations in reported delivery room practices for infants < 29 weeks' gestation across neonatal units in 12 networks of the International Network for Evaluating Outcomes in Neonates.

Growth and Variation in Fallow Deer (Dama dama L.) From Two Contrasting Habitats in Southern Britain

open access: yesActa Zoologica, EarlyView.
ABSTRACT We have compiled a unique data set on the age, sex, body weight and dimensions of over 500 European fallow deer from two contrasting areas of habitat in southern England: a high‐density managed parkland population and a lower‐density feral woodland one.

Modeling the Feasibility of Fueling CNG Heavy-Duty Trucks in Toronto, Canada

open access: yesFindings
Compressed Natural Gas (CNG) is cleaner than diesel for powering heavy duty trucks. A framework for establishing mobile on-site CNG refueling at truck yards is proposed and evaluated for the Greater Toronto and Hamilton Area (GTHA), Canada. The locations
