New Method for Simulation the Flexural Behavior of Fiber Reinforced Concretes With Combining the Finite Element and Section Moment Curvature [PDF]
پژوهشهای زیرساختهای عمرانی, 2020 Fiber reinforced concrete in tension is categorized based on tension softening behavior. Wide researchers have been studied this behavior and presented many tension softening models.

Multi-scale computational model for failure analysis of metal frames that includes softening and local buckling [PDF]
, 2010 In this work we present a new modelling paradigm for computing the complete failure of metal frames by combining the stress-resultant beam model and the shell model.

Calorimetric consequences of thermal softening in Johnson–Cook’s model [PDF]
, 2013 At high loading rates, the development of adiabatic shear bands in metals is conventionally attributed to the strong interactions induced by viscoplastic dissipation within the bands and thermal softening effects.

FEBS Letters, EarlyView.Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

The mechanism of stability of fault system inducing roof water-inrush
Energy Exploration & Exploitation, 2020 This paper analyzes the strain stability during mining, which often causes a water inrush. Mining couses costant stress on the fault zone, which is a loading process on the system composed of fault material and surrounding medium.

Molecular Oncology, EarlyView.Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

FEBS Open Bio, EarlyView.The crystal structure of Borrelia burgdorferi nicotinamidase (PncA/BBE22) reveals the correct full‐length protein initiated from a non‐canonical AUU start codon. The structure validates previous biochemical findings and resolves a long‐standing annotation error, demonstrating that the truncated database sequence is structurally incompatible with the ...

Experimental study of non-oxidized and oxidized bitumen obtained from heavy oil
Scientific Reports, 2021 Heavy oil and vacuum residue were used to obtain road bitumen BND 50/70 using two different methods of steam distillation at 323–362 °C and by oxidation, a method using packed column at temperature of 211–220 °C.

Heterotropic regulation and negative homotropic cooperativity
FEBS Open Bio, EarlyView.We identified a structural module common to some proteins that couple negative cooperativity with heterotropic regulation, two features that rarely coexist. These proteins are ring‐like and present an ordered asymmetry whereby noncontacting subunits are symmetric, and their tertiary structure differs from that of contacting subunits.

Preparation and Properties of Polylactic Acid/Modified Starch/POE Degradation Materials
MATEC Web of Conferences, 2018 Polylactic acid (PLA) / polyolefin elastomer (POE) / modified starch composites were prepared by melt blending. The composites were characterized by softening point, polarizing microscope, melt flow rate, tensile strength and degradation properties.
