Demulsifying agent simplified model for offshore oil wells

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This article addresses key challenges in offshore petroleum production caused by multiphase flow instabilities, such as slug flow and emulsion formation. Traditionally, severe slugging is mitigated by increasing wellhead backpressure through partial choke valve closure. In this context, a simplified dynamic model—the fast offshore wells model (

Spectrum, global bifurcation and nodal solutions to Kirchhoff-type equations

Electronic Journal of Differential Equations, 2018
In this article, we consider a Dancer-type unilateral global bifurcation for the Kirchhoff-type problem $$\displaylines{ -\Big(a+b\int_0^1 | u'|^2\,dx\Big)u'' =\lambda u+h(x,u,\lambda)\quad\text{in } (0,1),\cr u(0)=u(1)=0.

A Meta‐Analytic Review of Board Characteristics and Carbon Emission Disclosure: The Moderating Effect of Contextual Factors

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The relationship between board governance and corporate carbon emission disclosure remains persistently inconsistent across the empirical literature, despite decades of accumulated evidence. Drawing on agency, stakeholder, legitimacy, institutional, and upper echelons perspectives within a single analytical framework, we conduct a three‐level ...

Zebrafish ventral gastrula fate map reveals neural crest progenitor domain

Developmental Dynamics, EarlyView.
Abstract Background Fate maps relate progenitor cell positions to later fates and locations of their progeny, revealing early embryonic organization. Previous zebrafish fate maps identified the origin of germ layers and derivative cell fates, but ventral gastrula progenitor domains were not fully resolved. In particular, the neural crest, a multipotent

Gradient p‐p Orbital Hybridization in Bismuth‐Doped Crystalline Carbon Nitride for Dual‐Functional Carbon‐to‐Carbon Valorization

EcoEnergy, EarlyView.
Schematic illustration comparing the charge transfer dynamics and catalytic reaction over the (left) pristine carbon nitride and (right) Bi‐doped carbon nitride photocatalysts. In the pristine system, random charge diffusion and rapid recombination limit catalytic efficiency. In contrast, the Bi‐doped system establishes a robust internal electric field

Spatial variation in liana effects on host‐tree allometry and biomass in an intact tropical forest

Ecography, EarlyView.
Lianas are increasing in abundance across the tropics, yet local spatial variation in their effects on host‐tree allometry and biomass, and the drivers of this variation within forests, remain poorly understood. Using field inventory, drone photogrammetry, and terrestrial laser scanning (TLS) across a 50‐ha plot on Barro Colorado Island, Panama, we ...

Collective Anti‐Mattering: Belief That One's Group Is Being Disregarded Fuels Collective Action and Authoritarian Leadership Support Among Both Advantaged and Disadvantaged Groups

European Journal of Social Psychology, EarlyView.
ABSTRACT Groups are motivated not only by resources and status, but also by whether they matter to others. We introduce collective anti‐mattering, the belief that one's group does not count in the eyes of outgroups or society, and examine its emotional and political consequences.

Individuals Meaningfully Differ in How They Construct the Populist Subject of ‘the People’: Development and Initial Validation of the Popular Inclusion and Exclusion Scale

European Journal of Social Psychology, EarlyView.
ABSTRACT Despite the variety of populist manifestations, little research has dedicated itself to exploring this variation within and between individuals. Building on a discursive tradition, we propose that individuals meaningfully differ in how they construct the populist group of ‘the people’. Across three studies, we developed a popular inclusion and
