High-temperature rheological properties of amorphous poly-α-olefin/styrene-butadiene rubber composite modified asphalt

open access: yesHecheng xiangjiao gongye, 2023
Asphalt was modified by thermoplastic resin modifier amorphous poly-α-olefin (APAO) and styrene-butadiene rubber (SBR) and APAO/SBR composite modified asphalt was prepared. The basic properties of the composite modified asphalts were tested.

Experimental Study on the Cracking Resistance of Asphalt Mixture with Different Degrees of Aging

open access: yesApplied Sciences, 2023
The cracking resistance of asphalt mixture is a non-negligible issue. However, the cracking resistance evolution law, motivated by two factors (thermos-oxidative aging degree and test temperature), is not yet well understood.

Microvascular alterations in hypertension and vascular aging [PDF]

open access: yes, 2017
Hypertension and aging are characterized by vascular remodelling and stiffness as well as endothelial dysfunction. Endothelial function declines with age, since aging is associated with senescence of the endothelium due to increased rate of apoptosis and

Exercise for endurance and strength:Always separate? [PDF]

open access: yes, 2019
Physical training can be classified into three main types: endurance, resistance, and patterned movements. The first two of them have a significant impact on muscle phenotype and metabolism while patterned movement exercises concern changes in a motor ...

Effect of whey protein isolate on strength, body composition and muscle hypertrophy during resistance training [PDF]

open access: yes, 2008
Purpose of Review: Sarcopenia (skeletal muscle wasting with aging) is thought to underlie a number of serious age-related health issues. While it may be seen as inevitable, decreasing this gradual loss of muscle is vital for healthy aging.

Novel hybrid flax reinforced supersap composites in automotive applications [PDF]

open access: yes, 2015
Flax fibre bio-epoxy composites have not found many commercial uses in structural applications on account of their lack of cost efficiency and high susceptibility to environmental changes. Non-woven flax mats were subjected to alkali, acetylation, silane

Candida auris in the Age of Resistance [PDF]

open access: yesCureus, 2020
Candida auris (C. auris) is an opportunistic ascomycetous budding yeast that has been emerging as an invasive, multidrug-resistant pathogen over the past 10 years since its discovery. This fungi is the first to be labeled as a public health threat according to the Centers for Disease Control (CDC) and has since become a major problem in the United ...
