Dilatancy of cement slurries with chemical admixtures
Journal of Civil Engineering and Management, 2004 The results of experimental investigation of plasticising, airâ€entraining and viscosityâ€modifying admixtures with different chemical composition influence on rheological properties and dilatancy of cement slurries are presented in the article ...

YIELD STRESS MODIFICATION IN THE STRIP YIELD MODEL
Mechanics and Control, 2012 From among of the deterministic models for fatigue crack growth predictions suitable for metallic materials a Strip Yield (SY) model can be considered the most general and powerful crack growth prediction tool owing to its applicability to arbitrary variable amplitude load histories.

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome
FEBS Letters, EarlyView.This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Heat stress effects on yield parameters of selected rice cultivars at reproductive growth stages
, 2014 One of the overwhelming and deleterious effects of global warming on rice production is heat temperature resulting in rice crop during critical growth stages and consequently, yield and yield components decline. A glasshouse experiment has been conducted

FEBS Letters, EarlyView.An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Safe structural design for fatigue and creep using cyclic yield strength
, 2014 This study proposes cyclic yield strength (CYS, σ_cy) as a potential characteristic of safe design for structures operating under fatigue and creep conditions.

FEBS Letters, EarlyView.The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Yield trends and yield gap analysis of major crops in the world
, 2009 This study aims to quantify the gap between current and potential yields of major crops in the world, and the production constraints that contribute to this yield gap. Using an expert-based evaluation of yield gaps and the literature, global and regional

On the shakedown analysis of welded pipes
, 2011 This paper presents the shakedown analysis of welded pipes subjected to a constant internal pressure and a varying thermal load. The Linear Matching Method (LMM) is applied to investigate the upper and lower bound shakedown limits of the pipes ...
