Lifted flame property and interchangeability of natural gas on partially premixed gas burners

open access: yesCase Studies in Thermal Engineering, 2018
The relationship between lifted flames and burner head temperature of partially premixed gas burners supplied by various natural gas sources was investigated, and the application of AGA(American Gas Association) lifting limit for Chinese domestic gas ...

Thermodynamic effects of gas adiabatic index on cavitation bubble collapse

open access: yesHeliyon, 2023
In this paper, an improved multicomponent lattice Boltzmann model is employed to investigate the impact of the gas properties, specifically the gas adiabatic index, on the thermodynamic effects of cavitation bubble collapse. The study focuses on analyzing the temperature evolution in the flow field and the resulting thermal effects on the surrounding ...

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Use of Retention Index in Qualitative Gas–Liquid Chromatography [PDF]

open access: yesNature, 1964
IN a recent communication, Dhont1concluded that retention index2 data for non-polar solutes on apolar stationary phases were comparable between different workers and independent of experimental conditions.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

The effect of mine water pH on residual coal oxidation and its microscopic action characteristics

open access: yesMeikuang Anquan
In order to study the effect of pH value of mine water on the spontaneous combustion characteristics of residual coal in goaf, long-flame coal from Pingdingshan Coal Mine was used to analyze the gas production law and heat flow curves of gas derived from

Study of the multi-index coupling forecasting model of coal and gas outburst and its application

open access: yes工程科学学报, 2018
Coal and gas outburst seriously threatens the safety of underground coal mining. With the increase in coal mining depth, the geological conditions of coal mines become complicated, which adversely affects the safety of coal mining production.

Hippo pathway at the crossroads of stemness and therapeutic resistance in breast cancer

open access: yesMolecular Oncology, EarlyView.
Dysregulation of the Hippo pathway drives nuclear accumulation of YAP/TAZ, activating stemness‐related transcriptional programs that sustain breast cancer stemness and fuel therapeutic resistance across subtypes, underscoring Hippo signaling as a targetable vulnerability. Figure created and edited with BioRender.com.

Neutralino Annihilations and the Gas Temperature in the Dark Ages

open access: yes, 2007
Assuming the dark matter is made entirely from neutralinos, we re-visit the role of their annihilation on the temperature of diffuse gas in the high redshift universe. We consider neutralinos of particle mass 36 GeV and 100 GeV, respectively.
