From barriers to benefits: A personalized sleep intervention enhances sleep duration and emotional health in chronic short sleepers

British Journal of Psychology, EarlyView.
Abstract This pilot study evaluated a personalized sleep intervention incorporating motivational interviewing techniques to address sleep barriers, along with tailored sleep hygiene and extension for chronic short sleepers. Eleven university students completed a 14‐day sequential intervention (baseline, sleep hygiene and a combined phase adding 90‐min ...

Rhinoscopy in horses: Endoscopic anatomy, technique and equipment

Equine Veterinary Education, EarlyView.
Summary Rhinoscopy is a valuable imaging modality for diagnosis of conditions affecting the nasal and paranasal cavities in horses. Despite wide application in clinical practice, systematic endoscopic evaluation of the conchal bullae, nasal conchae and adjacent structures has seldom been described.

Rendering transparency to ranking in educational assessment via Bayesian comparative judgement

Review of Education, Volume 14, Issue 2, August 2026.
Abstract Transparency in educational assessment has become an increasingly pressing concern, particularly in the aftermath of the pandemic, as institutions seek more equitable, robust and defensible methods of evaluating student work. Comparative judgement (CJ) has gained traction as a promising alternative to traditional rubric‐based marking. However,

Clinical Management of Helicobacter Infection in Captive Baboons (Papio anubis and Papio hamadryas), and Isolation and Molecular Characterization of Three Novel Helicobacter Species

Journal of Medical Primatology, Volume 55, Issue 4, August 2026.
ABSTRACT Background Helicobacter spp. are gastric or enterohepatic bacteria that can be commensal, opportunistic, or pathogenic. Few studies have evaluated Helicobacter spp. in baboons. Methods Twenty‐seven captive baboons were surveyed for Helicobacter spp. by fecal PCR, and a subset evaluated by culture.

Dynamic behavior of a scroll compressor. (Dynamic analysis)

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1987
This study presents an analytical method to reveal the dynamic behavior of a scroll type compressor of small capacity. The calculated results are summarized on the basis of the gas-torque fluctuation, the crankshaft rotary behavior, the constraint forces at each pair of machine elements, the unbalanced forces of inertia, the compressor vibrations, the ...

Durability of domestic scroll compressor systems [PDF]

WIT Transactions on Engineering Sciences, 2009
A thorough surface examination of the main components of a scroll compressor after part uses was conducted. This was performed in order to identify the possible tribo-mechanical effects (abrasion, cavitation, erosion etc) which occur on the substrate of these components. Three dimensional interferometer surface scanning and scanning electron microscopy

From disorientation to preparedness: Information practices as scaffolding in acute crises

Journal of the Association for Information Science and Technology, Volume 77, Issue 7, Page 924-939, July 2026.
Abstract This qualitative study examines how adults in Israel enacted information practices during an acute national crisis. Using the information transitions framework, we investigate how concrete practices emerge and evolve across three stages: understanding, negotiating, and resolving. Semi‐structured Zoom interviews with 18 adults were analyzed via
