Lipid correction of hydrogen stable isotope ratios in fish
Limnology and Oceanography: Methods, EarlyView.Abstract Lipids are known to affect stable isotope ratio of organisms, especially δ13C values, and simple arithmetic lipid‐correction procedures have been developed based on the carbon to nitrogen ratio (C : N) that is a proxy for lipid content. Equivalent issues will likely arise with the increasing use of hydrogen isotopes in ecology, but as yet no ...

Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT Consider wave equations with time derivative nonlinearity and time‐dependent propagation speed which are generalized versions of the wave equations in the Friedmann–Lemaître–Robertson–Walker (FLRW) spacetime, the de Sitter spacetime and the anti‐de Sitter space time.

Nonexistence of solutions for quasilinear elliptic equations with p-growth in the gradient
Electronic Journal of Differential Equations, 2002 We study the nonexistence of weak solutions in $W^{1,p}_{{ m loc}}(Omega)$ for a class of quasilinear elliptic boundary-value problems with natural growth in the gradient.

Establishing Reciprocity as A Dimension of Nonprofit Entrepreneurial Orientation
Nonprofit Management and Leadership, EarlyView.ABSTRACT This study introduces and characterizes reciprocity as a distinct sixth dimension of entrepreneurial orientation (EO) within nonprofit organizations (NPOs), specifically Brazilian Medical Associations (BMAs). Through a qualitative exploratory study using 16 BMAs as units of analysis and data from 11 in‐depth interviews with nonprofit sector ...

Righting Past Wrongs Through Restorative Justice: Managerial Motivations for Collaboration
Nonprofit Management and Leadership, EarlyView.ABSTRACT Nonprofits are crucial to state collaborations as their embedded nature in communities allows them to gain the trust necessary to facilitate change and enhance strengths. As nonprofits collaborate with the public sector to tackle systemic challenges, understanding managerial motivations for collaboration and implications for social change is ...

Nonexistence results for weighted p-Laplace equations with singular nonlinearities
Electronic Journal of Differential Equations, 2019 In this article we present some nonexistence results concerning stable solutions to the equation $$ \hbox{div}\big(w(x)|\nabla u|^{p-2}\nabla u\big) =g(x)f(u)\quad \text{in }\mathbb{R}^N,\;p\geq 2 $$ when f(u) is either $u^{-\delta}+u^{-\gamma ...

Non-existence of solutions for a Timoshenko equations with weak dissipation [PDF]
Mathematica Moravica, 2018 In this paper, we consider the following Timoshenko equation utt + ( 2u ( M ((( ( u (( 2( ( u + ut = (u( q-1 u associated with initial and Dirichlet boundary conditions. We prove the non-existence of solutions with positive and negative initial energy.

Моделирование и анализ информационных систем, 2017 We consider a boundary-value problem for a singularly perturbed parabolic equation with an initial function independent of a perturbation parameter in the case where a degenerate stationary equation has smooth possibly intersecting roots.
