Effect of diesel injection pressure for enhancing combustion and reducing mechanical vibration and noise emissions in a non-road diesel engine

open access: yesEuropean Mechanical Science, 2023
In this study, the combustion, performance, emissions, noise, and vibration characteristics of a single-cylinder, four-stroke, air-cooled diesel engine used for non-road purposes were investigated by controlling different injection pressures with a ...

Analysis of injection pressure

open access: yesIOP Conference Series: Earth and Environmental Science, 2021
Abstract In the daily production of water injection wells, oil pressure is a very important production parameter. According to the existing theory, oil pressure plus liquid column pressure is the injection pressure at the bottom of the well, but this theory is contradictory to some production phenomena.

LABORATORY INVESTIGATION OF THE PERFORMANCE OF TWO-COMPONENT GROUT BEHIND THE SEGMENT IN SANDY SOILS BELOW THE WATER TABLE LEVEL

open access: yesRudarsko-geološko-naftni Zbornik
The increasing use of TBMs in urban areas has heightened the significance of grouting behind tunnel segments. A key aspect of mechanized tunnelling is the application of grout for injection behind the tunnel segments (support system) to prevent ground ...

Investigation on Key Parameters of N2 Injection to Enhance Coal Seam Gas Drainage (N2-ECGD)

open access: yesEnergies, 2022
Practice shows that CO2/N2-ECBM is an effective technology to enhance coalbed methane. However, there are few field tests in which the technology is applied to enhance the gas drainage in underground coal mines, and the effect is uncertain. In this study,

Constant Pressure Injection

open access: yes, 2023
AbstractIn practical hydraulic fracturing, limited by the operating power of the syringe pump and long transportation of pipelines, it is often difficult to maintain high pumping fluid pressure to crack the reservoir rock in deep formation.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.
