Emotional Ambivalence Contextualized: The Antecedents and Consequences of Daily Affective Profiles During Pregnancy

open access: yesJournal of Organizational Behavior, EarlyView.
ABSTRACT Research has increasingly highlighted the prevalence of emotionally ambivalent experiences for employees at work, with several self‐regulatory benefits emerging. Yet we do not have a full understanding of which work‐related contexts yield generative or maladaptive consequences of emotional ambivalence.

On the Polygonal Wear Evolution of Heavy-Haul Locomotive Wheels due to Wheel/Rail Flexibility and Its Mitigation Measures

open access: yesChinese Journal of Mechanical Engineering
Wheel polygonal wear can immensely worsen wheel/rail interactions and vibration performances of the train and track, and ultimately, lead to the shortening of service life of railway components. At present, wheel/rail medium- or high-frequency frictional

An Interactive Preoperative Virtual Reality Intervention for Breast Cancer Patients Undergoing Oncological Surgery: A Feasibility and Pilot Randomized Clinical Trial

open access: yesJournal of Surgical Oncology, EarlyView.
ABSTRACT Background and Objectives Preoperative anxiety is common before surgery and is associated with adverse outcomes, yet access to mental health support remains limited. We evaluated the feasibility and acceptability of a novel preoperative virtual reality (VR) prototype designed to reduce anxiety in patients undergoing cancer surgery.

Determining an Allowable Wear of Worm Wheels

open access: yesTransactions of FAMENA, 2017
The paper presents an analysis based on the two criteria used to determine an allowable sliding wear of the worm gear side teeth and of the worm wheels. In both cases, two undesirable consequences occurred. The first one is a reduction in the tooth root cross section, which may lead to tooth fracture.

Development of Cost‐Effective and Highly Transparent Melamine Formaldehyde Resin Modified With Sodium Chloride for Enhancing Glossiness and Abrasion Resistance of Melamine Impregnated Paper

open access: yesPolymer Engineering &Science, EarlyView.
An eco‐friendly melamine‐formaldehyde was produced by the addition of sodium chloride as a modifier. Modified MF resin improved surface gloss and abrasion resistance of decorative paper and decreased the formaldehyde emission. Curing time of the MF resin decreased with the addition of sodium chloride.
