Sinusoidal Condenser Corrugations for Condition-Dependent Enhancement of Single-Loop Pulsating Heat Pipes

Energies
Pulsating heat pipes (PHPs) are promising passive heat-transfer devices for compact thermal management; however, their performance is highly sensitive to channel geometry.

Delayed rainfall diminishes the positive response of soil respiration to warming

Grassland Research, EarlyView.
Warming stimulates soil respiration and its components, while delayed rainfall suppresses them. Crucially, delayed rainfall diminishes or even reverses the positive response of soil respiration to warming by intensifying the drought stress, and autotrophic respiration is more vulnerable than heterotrophic respiration under this interaction.

Refinement of the Quaternary seismic stratigraphy and analysis of buried glacial channels on the Labrador Shelf

Journal of Quaternary Science, EarlyView.
ABSTRACT The Laurentide Ice Sheet covered vast areas of North America during the Wisconsinan, including the Labrador Shelf, off the coast of eastern Canada. The shelf is characterized by glacial cross‐shelf troughs, which have been considered as predominantly eroded by the last ice advance.

Analysis of Mechanical‐Electrical‐Hydraulic Coupled Vibration Response Characteristics of Thermal Control Circulating Pumps Supported by Water‐Lubricated Bearings

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The operational reliability of thermal control circulation pumps is significantly restricted by the multi‐physics coupled environment. To reveal the vibration transmission mechanisms and dynamic response characteristics under multi‐field coupled excitations, a multi‐DOF coupled dynamic representation of the overall system, incorporating the ...

Continuous Respiratory Oscillometry in Pediatric Laparoscopic Surgery—The COMET Study

Pediatric Anesthesia, EarlyView.
ABSTRACT Background Laparoscopic appendectomy is the accepted surgical approach for appendicitis in centers worldwide. Laparoscopic surgery requires the creation of a pneumoperitoneum to facilitate surgical access. Laparoscopic surgery affects the respiratory mechanics of patients under general anesthesia.

Application of Non‐Isothermal Network Theory With Curved‐Channel Element Characteristics to Predict Melt Conveying in High‐Performance Single‐Screw Extruders

Journal of Polymer Science, EarlyView.
This study presents a fast and accurate calculation tool to predict conveying of polymer melts in single‐screw extruders. Integrating generalized sub‐models into network theory allows to represent the complex screw shapes and material behavior more realistically. Tests on an industrial extruder show close agreement with experiments, outperforming older

The Hidden Costs of Coffee Production in the Eastern African Value Chains

Sustainable Development, EarlyView.
ABSTRACT There is increasing recognition that significant hidden costs associated with agrifood systems are not reflected in market prices. Coffee is among the three most traded agricultural commodities in the world and supports the livelihoods of more than 30 million smallholder households.
