The exceptional stiffness and toughness of double-network hydrogels (DNHs) offer the possibility to mimic even complex biomaterials, such as cartilage. latter has a limited regenerative capacity thus needs be substituted with an artificial material. DNHs composed cross-linked poly(2-oxazoline)s (POx) poly(acrylic acid) (PAA) are synthesized by free radical polymerization in two-step process. re...

Laminated bamboo lumber (BLL) and scrimber (BS) are potential environmentally friendly building materials, considering that they hygroscopic materials their hygrothermal performance is closely related to the occupants’ comfort, durability, energy consumption. This study carried out material property tests on bamboo-based (BLL BS) analyzed simulations exterior wall constructions in five major cl...

Cemented carbides are used in the cutting tools industry thanks to their exceptional mechanical properties. Manufactured by powder metallurgy route, they made of a hard WC phase with ductile metallic binder, most commonly Co. Due lower availability Co and its classification as carcenogenic material REACH European Regulation, new binders have be considered: Fe Ni investigated this work. Because ...

This paper deals with the investigation of the microstructure and hardness of steel samples cladded with satellite 6-WC composites by using gas tungsten arc welding (GTAW) process. For this purpose, steel samples were coated with unreinforced and reinforced stellite (by 20, 30 and 40 wt.% WC). The cladded samples were evaluated by metallographic studies, microhardness measurement and X-ray diff...

introduction: evaluating body fat distribution is done through various methods. however, waist circumference(wc) measurement is a simple, cheap and valuable way. today a close consideration is given to wc assessment in order to evaluate physical health in epidemiological studies. wc depends on various environmental factors. identifying these factors can be used in health programs to promote wom...

ABSTRACT: In commercial pigs, the greatest susceptibility for pre-weaning mortality occurs in low birth-weight piglets. Despite their overall decreased birth weight, Meishan (MS) piglets have decreased preweaning mortality rates compared with contemporary Western breeds. The objective of the current study was to determine the contributions of the maternal uterine environment, piglet genotype, a...

Electrocatalysts for hydrogen oxidation reactions (HORs) are the key to renewable-energy technologies including fuel cells, hydrogen pumps, and water splitting. Despite the significant technological interest and tremendous efforts that have been made, development of hydrogen electrode catalysts with high activity at low cost remains a great challenge. Here, we report the preparation, characteri...

This research focuses on optimizing fermentation modification and papain enzymes. In manufacturing virgin coconut oil using the response surface methodology (RSM), experiment was carried out based Central Composite Design (CCD). Coconut yield, as a function of crude enzyme (CPE) mass (0–1 g) time (12–60 h), observed for 13 runs. The yield with natural without addition is 19%, 1 g enzyme, it can...
