Identification and characterization of a gene conferring stress resistance in Escherichia coli and cyanobacteria

open access: yesFEBS Open Bio, EarlyView.
Functional screening identified PcSyn14890, a cyanobacteria‐specific protein that enhances growth and stress resistance in E. coli and Synechocystis PCC6803. Although we expected it to function as a molecular chaperone, it was unable to protect against thermal aggregation of GAPDH.

Static Friction

open access: yes, 2016
Static friction is the force between two objects that are not moving relative to one another. This Demonstration shows what applied force is needed to overcome this static friction (and thus begin moving).

Study on Validity of Maximum Static Friction Coefficient as an Evaluation Value for Skid-Resistance of Pavement Surface

open access: yesThe Baltic Journal of Road and Bridge Engineering
The skid resistance of a pavement surface is a critical indicator of driving safety, typically quantified by the dynamic friction coefficient measured using a Friction Measurement Vehicle or a Dynamic Friction Tester. The dynamic friction coefficient is

Static and dynamic friction of hierarchical surfaces. [PDF]

open access: yesPhysical Review E, 2016
Hierarchical structures are very common in nature, but only recently have they been systematically studied in materials science, in order to understand the specific effects they can have on the mechanical properties of various systems.

Association of Elevated Platelets and C‐Reactive Protein With Severe Disease and Poor Survival in Systemic Sclerosis

open access: yesArthritis Care &Research, EarlyView.
Objective Elevated C‐reactive protein (CRP) levels in systemic sclerosis (SSc) have been linked with severe disease and worse survival, but the role of platelet levels remains unclear. This study examined whether elevated platelet levels, CRP levels, or both are associated with disease severity, progression, and survival in SSc.

Effects of deep friction massage and static stretching in non-specific neck pain

open access: yesMedical Journal of Dr. D.Y. Patil Vidyapeeth, 2019
Introduction: Neck pain is a frequent complaint of the era. The muscles around the neck tend to get shorter, leading to restricted neck mobility.

A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

open access: yesAdvanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Determination of Static and Dynamic Coefficients of Friction on Various Surfaces for Selected Haricot Bean Varieties

open access: yesLegume Science
When analyzing and designing equipment for postharvest handling, food processing, and storage, it is crucial to understand the coefficient of friction of legume crops on different structural surfaces.

Reduction in static friction by deposition of a homogeneous diamond-like carbon (DLC) coating on orthodontic brackets.

open access: yesDental materials journal, 2015
In orthodontics, a reduction in static friction between the brackets and wire is important to enable easy tooth movement. The aim of this study was to examine the effects of a homogeneous diamond-like carbon (DLC) coating on the whole surfaces of slots ...
