The objective of this study is to analyze the effects using surfactant (CTAB) and cellulose nanofibers (NFC) as an admixture in cement mortars. We examined composite properties porosity, compression energy, thermal conductivity hydration. results showed that with addition 0.7% by weight NFC per emulsion presence a cationic (CTAB). new material produced presented dry porosity between 4.7% 4.4%, ...

The present study focuses on exploring the effects of reactivity and degree dispersion BaCO 3 additions in manufacture sulfate-resistant OPC cements. A new electrochemical deposition method is attempted to effectively disperse particles (studying two different materials with particle size: D 50 = 11.45 2.37 μm) cement enhance their favour sulfate immobilisation form BaSO 4 . barium carbonate ad...

the major hydraulic phase in all the calcium aluminate cements including ciment fondue is ca (caal2o4). once hydrated, it starts to form the hexagonal crystals of cah10 and c2ah8 that depending on the time and temperature of hydration convert to the cubic crystals of c3ah6 and ah3. the nature, sequence, crystallinity and microstructure of hydrated phases of commercial refractory calcium alumina...

This study investigated the effects of drink composition on voluntary intake, hydration status, selected physiological responses and affective states during simulated gymnasium-based exercise. In a randomised counterbalanced design, 12 physically active adults performed three 20-min intervals of cardiovascular exercise at 75% heart rate maximum, one 20-min period of resistance exercise and 20 m...

infection is the primary source of mortality in burn patients. one of the main treatment methods of burn wound infections is topical antimicrobial therapy, in which drugs have to permeate a dead tissue called eschar. unfortunately, most antimicrobial agents can not permeate eschar in therapeutic levels. surprisingly, permeation properties of this barrier and effects of chemical or environmental...

Two experiments were conducted to evaluate the relationships between nutrients degradability, kinetics of hydration, functional specific gravity (FSG) of the three types of beet pulp (BP) including fine (FBP), normal (NBP) and pelleted (PBP) BP. In experiment 1, about 3 g of samples was weighed in sealed nylon bags (6 cm×7.5 cm, 40±5 µm pore size), incubated in rumen of two cannulated Holstein ...

physiologists have shown that increased fluids improve skeletal muscle performance in prolonged exercise.typical orders provide for 125 ml of intravenous fluids per hour in patients taking limited oral fluids during labor. our purpose in this study was to determine whether increased intravenous fluids affect the progress of labor. in a prospective randomized institutional clinical trial, one-hu...

This study analyzes the pore structure and durability of concrete according to four different ratios steelmaking slag powder (SSP). Concrete containing SSP increased formation gel capillary pores due delayed hydration, largest cumulative volume was observed when incorporation ratio 20%. In terms durability, had decreased performance compared without (NN), which changes in caused by incorporatin...

Despite the obvious significance, the aqueous interactions of peptides remain incompletely understood. Their synthetic analogues called peptoids (poly-N-substituted glycines) have recently emerged as a promising biomimetic material, particularly due to their robust secondary structure and resistance to denaturation. We describe comparative near-edge X-ray absorption fine structure spectroscopy ...

Proper hydration is essential for both mental and physical performance. The purpose of this study was to determine if hydration education would improve hydration status in collegiate athletes. A total of 120 college athletes, 60 each male and female, 30 each served as the control group (C) and as the intervention (I) group. A pretested questionnaire was used to evaluate the hydration knowledge,...
