Effects of wall heat loss on emission characteristics of liquid ammonia spray combustion using a swirling burner

Applications in Energy and Combustion Science
Liquid ammonia (LNH3) spray combustion is considered to achieve zero carbon emissions without the need for a pre-vaporization system, thereby reducing costs.

Evaluation of the combined impact of injection pressure and EGR on a diesel engine running on waste-recovered plastic biodiesel for environmental benefits

Results in Engineering
The present study investigates the performance and emission characteristics of a diesel engine operating on a 50 % waste plastic biodiesel blend (WPB50D50), evaluated under varying injection timings (19°, 21°, and 23° bTDC) and exhaust gas recirculation (

CX3CL1 in Early Detection of Alzheimer's Disease: Plasma Dynamics Across Age and Disease Stages

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Backgrounds Alzheimer's disease (AD) is characterized by amyloid‐beta plaques, tau tangles, and neuroinflammation. C‐X3‐C motif chemokine ligand 1 (CX3CL1, also known as fractalkine), a neuroimmune chemokine implicated in AD pathogenesis, shows inconsistent alterations in plasma/serum across studies.

Effects of Incremental Dietary Levels of Ground Flaxseed on Milk Production, Ruminal Metabolism, and Enteric Methane Emissions in Organic Dairy Cows [PDF]

, 2012
Ground Flaxseed (Linum uitatissimum) is a lipid supplement that is commonly fed to dairy cows. It is believed that supplemental lipid can change the Fatty Acid (FA) composition in the milk, and decrease methane production. Twenty lactating organic Jersey

EFFECT OF RICE STRAW AND NITRATE LEVELS IN SOIL SOLUTION ON NITROUS OXIDE EMISSION

Revista Brasileira de Ciência do Solo, 2015
Among the greenhouse gases, nitrous oxide (N2O) is considered important, in view of a global warming potential 296 times greater than that of carbon dioxide (CO2) and its dynamics strongly depend on the availability of C and mineral N in the soil.

TBK1‐Associated Primary Lateral Sclerosis Followed by Right Temporal Variant Frontotemporal Dementia

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT We report a 58‐year‐old woman with a novel splice‐site variant in the TANK‐binding kinase 1 (TBK1:c.993–2A>C p.Ala332TyrfsTer39) who sequentially developed primary lateral sclerosis (PLS) followed by right temporal variant frontotemporal dementia (rtvFTD). Neuroimaging demonstrated right anterior temporal atrophy before cognitive symptoms, and

Intense visible emissions from d 0 ions-doped silicate glasses

Journal of the Ceramic Society of Japan, 2008
A series of d° ions, i.e., Ti 4+ , Zr 4+ , Nb 5+ , Ta 5+ , Mo 6+ , and W 6+ , has been incorporated into silicate glass matrix by utilizing a conventional melt-quenching method, and their optical properties have been examined. When the resultant glasses are excited by ultraviolet light, intense emissions are observed in the blue to orange wavelength ...
