Wild, liquid state culture and solid state culture of Taiwanofungus camphoratus (Chang-chih) were sequentially extracted with cold water, methanol, and hot water to get cold water soluble, methanol soluble, and hot water soluble extracts respectively. The extracts from three Chang-chih were used to determine 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, semicarbazide sensitive amine ...
Antimicrobial activities of the leaf extracts of Cymbopogon citatrus (lemongrass) and Vernonia amygdalina (bitter leaf) and the seed extracts of Garcinia kola (bitter kola) were carried out. G. kola had effect only on Staphylococcus aureus and Escherichia coli with no inhibition on Candida albicans. Ethanol, cold water and hot water extracts of Vernonia amygdalina and Cymbopogon citratus showed...
The aim of this study was to evaluate the effect of silanization protocols on the bond strength of two resin cements to a lithium disilicate glass-ceramic. Thirty-two ceramic discs were assigned to 2 groups (n=16): G1 - dual-cured resin cement and G2 - light-cured resin cement. Four subgroups were evaluated according to the used silanization protocol. The glass-ceramic was etched with 10% hydro...
We investigated Legionella and Pseudomonas contamination of hot water in a cross-sectional multicentric survey in Italy. Chemical parameters (hardness, free chlorine, and trace elements) were determined. Legionella spp. were detected in 33 (22.6%) and Pseudomonas spp. in 56 (38.4%) of 146 samples. Some factors associated with Legionella contamination were heater type, tank distance and capacity...
The innovative hot stamping press of quenchable steel mainly includes two stages: hot forming of blank at elevated temperature and quenching of hot stamped part in closed water-cooled tools. Crucial stage in hot stamping process is quenching of hot formed part in water-cooled tool to achieve final high ultimate tensile strength. In quenching stage, cooling rate of hot stamped part has a signifi...
BACKGROUND Use of alkaline peroxide denture cleanser with different temperature of water could cause a change in surface hardness of the acrylic denture and also has a bleaching effect. The purpose of the study was to determine the effect of increased water content during thermal cycling of hot water-treated acrylic on the surface hardness of acrylic denture base when compared to warm water tre...
OBJECTIVES To assess the effectiveness of thermostatic mixing valves (TMVs) in reducing bath hot tap water temperature, assess acceptability of TMVs to families and impact on bath time safety practices. DESIGN Pragmatic parallel arm randomised controlled trial. SETTING A social housing organisation in Glasgow, Scotland, UK. PARTICIPANTS 124 families with at least one child under 5 years. ...
The effects on sleep of a hot drink of milk and Horlicks were compared with those of hot water taken before retiring by medical student volunteers. Horlicks reduced the number of small movements made during sleep.
Shower heads and hot-water faucets containing Legionella pneumophila were evaluated for aerosolization of the organism with a multistage cascade impaction air sampler. Air was collected above two shower doors and from the same rooms approximately 3 ft (91 cm) from the shower doors while the hot water was running. Low numbers (3 to 5 CFU/15 ft3 [0.43 m3] of air) of L. pneumophila were recovered ...
the aim of this study was investigation of the effects of pretreatments (hot water blanching and chemical treatments) by hot air and sun drying methods on mass transfer kinetics during red chili pepper rehydration phenomenon. for these purposes fick's second law and peleg model were applied for modeling of red chili pepper rehydration phenomenon. the results revealed that, peleg model coul...
