Light-Absorbing Impurities in Snow: A Personal and Historical Account

open access: yesFrontiers in Earth Science, 2019
The ability of light-absorbing impurities (LAI) to darken snow had been known for decades, even inspiring practical applications, but quantification of the radiative forcing awaited radiative-transfer modeling in 1980 and measurement of soot in Arctic ...

CFD Predictions of Soot & CO Emissions Generated by a Partially-Fueled 9-Element Lean-Direct Injection Combustor [PDF]

open access: yes
A study was undertaken to investigate the CO & soot emissions generated by a partially-fueled 9- element LDI (Lean-Direct Injection) combustor configuration operating in the idle range of jet engine conditions.

Class Hierarchy Complementation: Soundly Completing a Partial Type Graph [PDF]

open access: yes, 2013
We present the problem of class hierarchy complementa- tion: given a partially known hierarchy of classes together with subtyping constraints (“A has to be a transitive sub- type of B”) complete the hierarchy so that it satisfies all con- straints.

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

open access: yesFire 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.

Asymmetric Information With Multiple Risks: The Case of the Chilean Private Health Insurance Market

open access: yesHealth Economics, EarlyView.
ABSTRACT We extend the Rothshild and Stiglitz (1976) model to two sources of risk –inpatient and outpatient risk– to better proxy real‐world health insurance markets. We uncover an interesting theoretical possibility: Take individuals A and B, who are low risks in, say, the inpatient dimension but A is riskier in the outpatient dimension.

Application of a Detailed Emission Model for Heavy Duty Diesel Engine Simulations Application d'un modèle détaillé d'émissions pour la simulation de gros moteurs diesel

open access: yesOil & Gas Science and Technology, 2006
A detailed chemical model describing the formation of soot and NO is applied to simulate emission formation in a heavy duty diesel engine. Cylinder flow and spray development is simulated using an engine CFD code - Speedstar.

Negative learning emotions and learning goal orientation in teams: HRD implications

open access: yesHuman Resource Development Quarterly, Volume 36, Issue 1, Page 49-67, Spring 2025.
Abstract Utilizing insights from team regulation theory and social cognitive theory, this research conducted empirical testing through a field survey involving engineering teams. This research is significant as it inspires teams to effectively harness their learning capacity, thereby enhancing collective motivation for future success.

Soot formation and radiation in turbulent jet diffusion flames under normal and reduced gravity conditions [PDF]

open access: yes
Most practical combustion processes, as well as fires and explosions, exhibit some characteristics of turbulent diffusion flames. For hydrocarbon fuels, the presence of soot particles significantly increases the level of radiative heat transfer from ...

Perceived Partner Responsiveness Is Associated With Adolescent Sexual Wellbeing Over 1 Year

open access: yesJournal of Adolescence, EarlyView.
ABSTRACT Introduction Research on adolescent sexuality is primarily cross‐sectional and often neglects interpersonal factors that may play a key role in promoting their sexual wellbeing, such as perceived partner responsiveness, that is, feeling understood, cared for, and accepted by a partner.
