A Path Analytic Investigation of Job-Related Tension: A Case for Sales Management

open access: yesMarketing Management Journal, 1999
This study examined sources and outcomes of job tension and the mediating role of work-family conflict and job tension in linking role stressors with work affective constructs.

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Effect of Direct Current on Interfacial Tension of Condensate Droplet Immersed in Brine

open access: yes, 2021
Several methods have been applied to mitigate condensate banking effect observed in gas condensate reservoirs. Some of these methods have significant impact on the environment (subsurface and surface).

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Experimental study on tension-shear mechanical behavior of sandstone

open access: yesYantu gongcheng xuebao, 2019
Rock excavation and river incision result in stress unloading in one or more directions, which leads to the redistribution of stress fields of rock masses in the influenced zone.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

A New Method to Test the Fracture Energy Based on Direct Tension

open access: yes, 2011
Fracture energy, which reflects the split property of brittle materials, is a significant parameter. For present tests of measuring it, the indirect test itself has insuperable disadvantage, while the direct tension test, in spite of an ideal way, is too

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Direct and Indirect Measurement of Complex Poisson's Ratio - Indirect Measurement in Torsion and Tension

open access: yes
This data set contains indirectly calculated complex Poisson's ratio by determining the complex Young's E* and complex shear modulus G* from torsion and tension measurements. The measurements were performed on cylindric polymethyl methacrylate (PMMA, EH-

Inversion-based control of electromechanical systems using causal graphical descriptions [PDF]

open access: yes, 2006
Causal Ordering Graph and Energetic Macroscopic Representation are graphical descriptions to model electromechanical systems using integral causality. Inversion rules have been defined in order to deduce control structure step-bystep from these graphical
