This paper compares the alkali-activated fly ash (AAFA) manufactured with thermal oven curing and pulsed microwave curing methods. Fly ash activated by 8M NaOH solution at a liquid to solid ratio of 0.3 was cured by thermal oven at 85°C and domestic microwave oven, respectively. Apart from compressive strength test, the temperature profiles of AAFA samples were captured by thermal camera. React...

The main objective of the study was to compare the effects of halogen lamp–microwave combination baking on quality of breads with other baking methods (conventional, microwave and halogen lamp baking). It was also aimed to improve the quality of microwave baked breads by using combination oven. Weight loss, specific volume, firmness and color of the breads were measured as quality parameters. H...

background: sterilization techniques could affect the characteristics of orthodontic wires. the aim of the present study was to evaluate the effect of steam and dry heat sterilization techniques on load-defl ection behavior of fi ve types of β-titanium alloy wires. materials and methods: the samples consisted of 30 straight lengths of fi ve types of β-titanium alloy wires: titanium molybdenum a...

background : agaricus blazei mushrooms are one of the most important edible and therapeutic mushrooms, and they contain minerals, vitamins, and amino acids essential for the human body. this mushroom is used raw, dried, and in the form of pharmaceutical products. one of the most important processes after harvesting is drying in order to enhance the quality and the length of maintenance of the p...

in this research an experiment based on completely randomized design with three replications and 11 treatments was conducted of mentha piperita. treatments consisted of dryer drying, artificial shade drying, oven drying (50 and 70 °c), and microwave drying with different powers (100, 180, 300, 450, 600 and 900 w) and fresh sample as control. the end time of each treatment determined on the basi...

OBJECTIVE This study examined the effectiveness of microwave ovens in assisting elderly persons with disabilities with cooking food. METHOD The participants were five elderly persons who had gross motor, fine motor, or vision impairments but no cognitive impairments. Before the study, none of the participants owned or operated a microwave oven. In this single-subject design of four phases (AB...

The objective of the present study was to evaluate the effect of sintering condition on matrix formation and subsequent drug release from polymer matrix tablet for controlled release. The present study highlights the use of a microwave oven for the sintering process in order to achieve more uniform heat distribution with reduction in time required for sintering. We could achieve effective sinte...

sterilized soils are commonly used for the study of xenobiotic sorption and as an abiotic control in biodegradation experiments. they are also used for the chemical study of nitrogen and carbon cycle processes and the elimination of the biological factors. in this research the effects of different soil sterilization methods such as autoclaving, fumigating and exposure to ultraviolet and microwa...
