AIMS To investigate the reaction of antibodies OV 632 and MOC 31 in paraffin wax sections as opposed to frozen sections and cytological preparations; to evaluate their usefulness in the differential diagnosis of malignant mesothelioma and secondary adenocarcinoma of the pleura; and to assess the efficacy of microwave pretreatment of sections in unmasking their associated epitopes. METHODS Imm...

in this research, microwave-assisted hydrodistillation (md) with pretreatment ultrasound (us) 45 and 90 min of essential oils from fresh aegle marmelos peel were used and the results were compared with those obtained by hydrodistillation technique (hd) in terms of extraction yield/efficiency, extraction time, chemical composition and quality of the essential oil. all experiments were performed ...

This study discusses the application of microwave-based heating for the pretreatment of biomass material, with Pennisetum purpureum selected for pretreatment. The Taguchi method was used to plan optimization experiments for the pretreatment parameter levels, and to measure the dynamic responses. With a low number of experiments, this study analyzed and determined a parameter combination in whic...

The effect of different extraction methods rosemary leaves on the total phenolic content (TPC), and antioxidant activity extracts was herein investigated. Firstly, solid-liquid conventional (CEM) microwave-assisted (MAE) were implemented in an effort to identify solvent microwave irradiation extract quality. obtained from CEM at room temperature, using ethanol/water 95:5 v/v, showed highest (IC...

This study was undertaken to evaluate the efficiency of a liquid-solids separation process and microwave pretreatment, as well as anaerobic biodegradability of microwave pretreated dairy manure. Liquid-solids separation of raw dairy manure resulted in solid and liquid fractions having different properties, with the solid fractions richer in total and volatile solids content and liquid fractions...

Biological attack of pyrite is a potential method of reducing pyritic sulphur in coal. Integration of such attacks with microwave pretreatment can enhance the efficiency of the process. Alternatively, processes such as oil-agglomeration can be coupled with the biological attack to obtain higher rates of pyritic sulphur removal. In this study desulphurization of Indian (Assam) coal was carried o...

The effect of microwave and blanch pretreatments on the drying kinetics and quality of white yam (Dioscorea rotundata) was investigated. Yam cubes destined for hot air drying at temperatures 70-90°C were predried in a domestic microwave or blanched in hot water for 1-5 min. Microwave pretreatment time had a positive significant effect on drying rate but both pretreatments had a negative influen...

Lignocellulosic biomass is included in the group of renewable energy sources. Its calorific value high, owing to which it can be successfully used production second-generation fuels, e.g., biogas. However, its complex structure makes necessary apply a pretreatment order increase biogas output. This study presents usability pulsed electric field grass silage methane fermentation and compares wit...

The effects of microwave pretreatment on disintegration and mesophilic digestion of waste activated sludge (WAS), primary sludge (PS), combined (PS + WAS) sequencing batch reactor (SBR) sludge and anaerobically digested biocake were investigated by both household and bench scale industrial types microwaves at temperatures below and above boiling point. Pretreatment variables, temperature, inten...
