the use of recycled bassanite, produced from gypsum wastes, in ground improvement projects is initiated recently in japan to eliminate the huge quantities of gypsum wastes. meanwhile the use of recycled bassanite has a positive effect on the environment and economy, it has many challenges. these challenges are related to the release of fluorine more than the standard limits results in contamina...

biopolymers are environmental friendly sources as renewable and sustainable substituents for petroleum-based polymers. application of these polymers is common in variety of industries including papermaking. herbalexudate gums have been used in papermaking industry for decades, especially paper recycling. in this study, gum polysaccharide exudates from baridje plant  (ferula gummosa) extracted a...

in this investigation, the mechanical properties of the blends of blown bitumen110/10, heavy vacuum slops (h.v.s), bitumen 60/70 penetration grade and isotactic polypropylene (ipp) were studied for the first time. our results showed that modulus varies non-linearly and at certain asphaltenes contents a peak appears. considering these phenomena it is revealed that in the absence of ipp, interact...

Synaptic vesicles in rodent neurons are recycled using at least two distinct mechanisms.

Effects of bedding with recycled sand and season on lying behaviors, hygiene, and preferences of late-lactation Holstein cows were studied. It was hypothesized that recycled sand will decrease lying time and increase hygiene scores due to increased moisture content and organic matter, and thus a preference for the control sand will be evident. Cows (n = 64) were divided into 4 groups (n = 8 per...

batch culture of ralstonia eutropha using the recycled gas closed circuit culture system was conducted in order to develop a practical fermentation system for industrial autotrophic culture for poly (hydroxybutrate) production. the gas phase of the culture system consisted of substrate gas so that gases in this culture could be recycled as long as the amount of the gas consumed would be repleni...

The Non-Linear Strain Energy Equivalence Theory, a semi-empirical model, is utilized to predict longterm creep from short-term compressive stress-strain experiments conducted at different strain rates. Stress-strain experiments in uni-axial compression are performed at strain rates of 3 and 0.03 %/minute to predict creep behavior and stress-strain data at several strain rates for an immiscible ...
