Multiple tools to investigate the origin of the exotic species Chinook salmon Oncorhynchus tshawytscha (Walbaum, 1792) (Salmonidae) in the world's largest chocked coastal lagoon. [PDF]

J Fish Biol
Abstract Salmonid species have increasingly been established in South America for aquaculture and recreational fishing purposes. This study provides the first scientific record of the Chinook salmon (Oncorhynchus tshawytscha) in the Patos Lagoon (32°S), the world's largest choked coastal lagoon.

Comparative CFD simulations of a hydrogen fire scenario [PDF]

, 2017
Hydrogen leakage and fire ignition and propagation are safety concerns in several industrial plants. In a nuclear fusion power plants the separation of hydrogen and tritium takes place in different steps, among which one or more electrolyzers are ...

Simulation of non-Newtonian gas-focused micro-jets in chocked gas flow regime

Journal of Physics: Conference Series
Abstract Stable liquid jets are crucial for successful serial crystallography experiments. They are produced from gas dynamic virtual nozzles (GDVNs), where the liquid from an inner capillary is focused by a co-flowing gas from an outer converging capillary.

Characterizing gas flow from aerosol particle injectors

, 2017
A novel methodology for measuring gas flow from small orifices or nozzles into vacuum is presented. It utilizes a high-intensity femtosecond laser pulse to create a plasma within the gas plume produced by the nozzle, which is imaged by a microscope ...

Questions Should Have Answers

European Journal of Philosophy, EarlyView.
ABSTRACT Making sense of the world often requires one to come up with new ideas, including ideas one had previously been unable to think of. How and when should this be done? I propose and defend a norm of rationality linking wondering, belief, and abilities to conceive: one must not both wonder a question and reject all answers to it that one can ...

Relativistic Photon Mediated Shocks

, 2008
A system of equations governing the structure of a steady, relativistic radiation dominated shock is derived, starting from the general form of the transfer equation obeyed by the photon distribution function. Closure is obtained by truncating the system

Co‐Design at the Boundary: Understanding the Dynamics of Open Innovation Between Companies and Communities

Journal of Product Innovation Management, EarlyView.
ABSTRACT For over two decades, firms have built platforms and engaged open innovation communities to improve and customize their products through widened participation in the design process. While the benefits of involving those outside a firm as co‐designers have been well described, how co‐design processes unfold over time at the boundary between ...

Large Eddy Simulation of Near-Nozzle Shock Structure and Mixing Characteristics of Hydrogen Jets for Direct-Injection Spark-Ignition Engines [PDF]

, 2014
Due to the ever increasing prices of conventional fossil fuels, as well as climate change and sustainability issues, several liquids and gases have been proposed as alternative fuels for internal combustion engines. Hydrogen has been investigated

Trust in Regulation in a Time of Revolution

Regulation &Governance, EarlyView.
ABSTRACT This article examines trust in regulation as a core value and precondition of the modern liberal democratic regulatory state. It develops a concept of justified trust in regulation, grounded in regulatory trustworthiness—honesty, competence, and reliability—rather than in proxies such as partisan loyalty, blind faith, obedience, or resignation.

Examining the Relationship Between Time Spent on Social Media Platforms and Body Image Concerns

European Eating Disorders Review, Volume 34, Issue 2, Page 313-320, March 2026.
ABSTRACT Objective Research has suggested that a relationship may exist between frequent use of social networking sites (SNSs) and body dissatisfaction; however, there is a lack of research around newer SNS platforms with larger visual imprints, such as TikTok and Snapchat.
