Durability of Soft Pneumatic Actuators: A Review and Benchmarking Protocol

Advanced Robotics Research, EarlyView.
Lack of durability is a key challenge hindering the broad scale adoption of soft pneumatic actuators (SPAs) in automation industries. This review provides a comprehensive overview of existing research on SPA durability, introduces a standardized durability benchmarking protocol to consolidate the testing of SPAs, and outlines promising directions for ...

Cross Kingdom Metabolic Engineering Paradigm Elevating Sustainable Protein Production

Advanced Science, EarlyView.
ABSTRACT Confronting the dual crisis of escalating global protein demand and unsustainable agriculture necessitates transformative solutions. Here, we pioneer evolutionary insights from maize nitrogen optimization via asparagine synthetase (ASNS) to rewire metabolism in Pichia pastoris.

Pull Off test to evaluate the compressive strength of concrete: an alternative to Brazilian standard techniques

Revista IBRACON de Estruturas e Materiais
To estimate the compressive strength of concrete is necessary in many reinforced concrete structures inspection works. In Brazil, the standard tests for this purpose are: Compressive test in drilled cores, rebound hammer test and ultrasonic test.

Comparison of the inherent variability in rebound hammer tests performed with different testing instruments

Epitoanyag - Journal of Silicate Based and Composite Materials, 2013
The rebound hammer test of concrete can provide an alternative to drilled core tests for estimating the in-situ compressive strength of concrete. The variability of concrete strength is recognised during the strength assessment and the design strength of concrete is specified as its characteristic compressive strength by taking the variability of the ...

Evaluation of Rebound Hammer Test as a Combined Procedure Used With Drill Core Testing for Evaluation of Existing Structures

, 2012
Rebound hammer is a non-destructive test method often used to assess the surface hardness of engineering materials. The method is used as a part of the procedure applied to evaluate existing structures.

Bio‐Inspired Gradient Coatings Enhance the Leading Edge Erosion Resistance of Wind Blades

Advanced Science, EarlyView.
Rain‐induced erosion of the wind turbine blade leading edge poses a critical challenge to maintenance and operation. Here, we propose a bio‐inspired approach for erosion protection utilising a platelet‐reinforced polyurethane coating with a graded through‐thickness architecture.

Correlation Between Cerchar Abrasivity Index with Rock Properties in Sandstone and Tuff Samples [PDF]

Muhandisī-i manābi̒-i ma̒danī
The abrasivity of materials is of vital importance in selecting an affordable excavation method in the early stages of a tunneling project. The amount of specific energy and the Mode I and Mode II stress intensity factors in the eroded disc is more than ...

Studies on the spatial variability of rebound hammer test results recorded at in-situ testing

Epitoanyag - Journal of Silicate Based and Composite Materials, 2013
Variability of the in-situ rebound hammer tests is composed of the inherent variability of the measuring method and the spatial variability of the concrete performance properties. In-situ, Schmidt rebound hammer tests were performed at the bottom surface of a concrete slab, with dimensions of 25.0 m × 7.5 m.

Plasma HIV viral rebound following protocol-indicated cessation of ART commenced in primary and chronic HIV infection. [PDF]

, 2012
OBJECTIVES: The magnitude of HIV viral rebound following ART cessation has consequences for clinical outcome and onward transmission. We compared plasma viral load (pVL) rebound after stopping ART initiated in primary (PHI) and chronic HIV infection (CHI)
