Microwave dyeing was carried out under a variety of conditions in terms of the power and time of a microwave to investigate the effects of microwaving on the dyeability of acrylic fibers. It was found that the dyeability of acrylic fibers were significantly improved under microwave irradiation caused by the increased adsorption of the dye into fibers due to the local over heating and an amplifi...

background: the biological solids produced during wastewater treatment processes are called sludge. as sludge contains various sickening microorganisms such as pathogens, organic and inorganic substances and has adverse effects on human and environment, therefore it should be treated and processed entirely prior to disposal and then disposed in line to the environmental regulations. thermal tre...

Background and Objective: Hodgkin's lymphoma is a potentially curable hematologic malignancy with difficulty in its diagnosis especially in atypical cases even in expert hands. Today, immunohistochemistry plays a significant role in the diagnosis of it especially applying the anti-CD15 and anti-CD30 antibodies. The negativity of CD15 can be reduced by antigen retrieval for meth...

microwave-assisted hydrodistillation (mahd) method has been compared with hydrodistillation (hd) conventional technique for extraction of essential oil from achillea millefolium. microwave-assisted hydrodistillation were examined at three levels of microwave powers (300, 500, and 700 w) .   obtained results show that   mahd offers important advantages over hd in terms of energy savings and extr...

the genus haplophyllum, which belongs to the rutaceae family, includes 18 species in iran. in this study, after collecting plant material, botanical identification and suitable drying, the essential oils from aerial parts of haplophyllum robustum bge. were extracted by three different isolation techniques, conventional hydrodistillation (hd), microwave-assisted hydrodistillation (mahd) and solv...

The purpose of the research was to study the effect of microwave power inpretreatment of fresh waterhyacinth on biogas production. The variations of microwave power levels are 240; 400; 560 and 800 W. The variations of microwave heating time are 5; 7 and 9 min. The unpretreated fresh water hyacinth are used as control. The result of research showed that the microwave pretreatment of fresh water...

background: cutaneous leishmaniasis caused by l. major is an important public health problem in endemic areas. the aim of this study was to explore the therapeutic effect of microwave and or infrared radiation in the treatment of lesion induced in balb/c mice by l. major inoculation. methods: the footpad lesion was induced in balb/c mice by inoculation of l. major promastigotes subcutaneously. ...

The influence of microwave treatment on the surface roughness, hydrophobicity, and chemical composition of galena was studied. The pure galena specimens and purified galena concentrate were used in this work. A conventional multi-modal oven (with a frequency of 2.45 GHz and a maximum power of 900 W) was used to conduct the experiments. The results obtained from the atomic-force microscopy analy...

this study aimed to examine the effectiveness of combined microwave-ultrasonic pasteurization system on escherichia coli and vitamin c content in sour cherry juice (scj). based on the findings, microwave output power, ultrasound power, and ultrasonic exposure time as well as the microwave-induced temperature were the most effective factors in reducing e. coli and vitamin c content. in addition,...
