Experimental and Numerical Investigation of Cedar Façade Flame Spread With Respect to Sidewall

Fire and Materials, EarlyView.
ABSTRACT In response to growing energy conservation and carbon neutrality efforts, façade systems incorporating wooden materials have attracted increasing attention, which in turn raises concerns about their combustibility. This study presents a combined experimental and numerical investigation of flame spread along cedar façades.

An Experimental Investigation on the Impact of Burner Height and Location on the Characteristics of Externally Venting Flames

Fire and Materials, EarlyView.
ABSTRACT Fire sources in actual compartment fires exhibit a predominantly uneven spatial distribution. In this context, the impact of the height and location of the fire source, as well as the heat release rate (HRR) of the fire, on the thermal characteristics of Externally Venting Flames (EVF) is experimentally investigated.

Microbiome—pancreatic cancer crosstalk: From tumor biology to therapeutic intervention

iMetaOmics, EarlyView.
The intratumoral microbiome acts as a critical regulator in pancreatic cancer progression and therapeutic resistance. This comprehensive review delineates the origins of pancreatic microbes, elucidates their multifaceted mechanisms in driving immune suppression, metabolic reprogramming, and stromal desmoplasia, and highlights the clinical potential of ...

Effect of AEA-SP Dosage Sequence on Air Entrainment in FA Concrete

Nordic Concrete Research, 2019
Laboratory measurements show that varying the dosage sequence of air-entraining agent and co-polymer in the mix (SP added before, after or together with AEA) greatly affects air entrainment in fresh and hardened fly ash concrete.

INVESTIGATION ON EFFECTS OF ENLARGED PIPE RUPTURE SIZE AND AIR PENETRATION TIMING IN REAL-SCALE EXPERIMENT OF SIPHON BREAKER

Nuclear Engineering and Technology, 2014
To ensure the safety of research reactors, the water level must be maintained above the required height. When a pipe ruptures, the siphon phenomenon causes continuous loss of coolant until the hydraulic head is removed.

Decoupling glacier retreat and surface stabilization on the Snežnik Plateau (Slovenia), insights from in situ cosmogenic 36Cl exposure and depth‐profile ages

Journal of Quaternary Science, EarlyView.
ABSTRACT Glaciokarst landscapes pose distinctive challenges for cosmogenic dating because meltwater and runoff can be rapidly rerouted into ponors and conduit networks, weakening glacier–river coupling and promoting local sediment storage. We reconstruct glacier retreat and postglacial stabilization on the Snežnik Plateau (SW Slovenia) using in situ ...

Eliminating air entrainment in complex siphon drainage systems: a physical modelling approach

Discover Applied Sciences
The generation of persistent foam in the cooling water discharge of coastal power plants poses significant environmental and operational challenges. This phenomenon is fundamentally driven by a "hydro-chemical coupling" mechanism, where hydraulic air ...
