Detection of Toxoplasma gondii in blood by means of the polymerase chain reaction (PCR) may facilitate early diagnosis of toxoplasmosis in different groups of patients. We evaluated this approach in 42 patients presenting with ocular or psychotic diseases by comparing the sensitivity and specificity of PCR after heat treatment using a microwave oven with a standard genomic DNA extraction method...

Electromagnetic radiation still is a new and exotic option in food and beverage processing, though it gradually is finding niches in various applications as research engineers overcome the practical barriers to commercial use. From relatively benign radio waves to highly destructive gamma waves, electromagnetic radiation has been used for everything from drying crackers to meat sterilization. T...

The composite powders of barium-magnesium ferrite were prepared using sol-gel auto-combustion and microwave methods. The crystal structure and the shape of nanocomposites have been compared. X-ray Diffraction (XRD), Scanning Electron Microscope (SEM) and Vibrating Sample Magnetometer (VSM) were used to investigate the structural, morphological and magnetic properties of nanopowder. The formatio...

introduction nowadays, due to higher environmental pollution and decreasing fossil fuels many countries make decisions to use renewable fuels and restrict using of fossil fuels. renewable fuels generally produce from biological sources. biodiesel is an alternative diesel fuel derived from the transesterification of vegetable oils, animal fats, or waste frying oils. considering the differences be...

Hydroxyapatite (HA) is one of the most common biocompatible ceramic with wide usages in various aspects of medicine due to the resemblance to the mineral bone tissue. The particle size of HA has a key roll in determination of the reaction rate at the interface of natural bones/artificial. Accordingly, this paper tries to propose a novel approach for the preparation of HA nanoparticles from natu...

The heat pipe applications have been coupled with the renewable energy such as solar energy, waste heat and geothermal energy. Thermosyphon Rankine Cycle (TRC) is a vertical wickless heat pipe engine. In this engine, the turbine is installed between the insulated section and a condenser section of thermosyphon. The mechanical energy developed by the turbine can be converted to electricity, by d...

A dual-source model treating the energy balance of the than measured. An empirical model was developed to reduce this bias, but it is not known how generally applicasoil/substrate and vegetation that was developed to use radiometric surface temperature observations is revised to ble it will be. Model sensitivity to typical uncertainties in remotely sensed leaf area index (LAI) and near-surface ...

Elephant foot yam (EFY) includes a high degree of nutritious fiber, carbohydrates, glucose, protein, and sugars. It also has plenty calcium, sodium, potassium, vitamin C, is promising source starch. Due to the presence oxalate acridity, EFY been extensively underused. Researchers have employed variety ways decrease calcium oxalate, including boiling NaCl treatment. A novel technique like ultras...

Many minerals are effective absorbers of microwave energy, whereas in general gangue materials are not. This suggests applying microwave heating to mineral processing to effect selective heating of minerai phases. Many mineral processing applications have been tested only on a laboratory scale; the engineering realities of large-scale operations have largely been overlooked. Of particular conce...

In this note we investigate the effects of perturbations in a dark energy component with a constant equation of state on large scale cosmic microwave background anisotropies. The inclusion of perturbations increases the large scale power. We investigate more speculative dark energy models with w < −1 and find the opposite behaviour. Overall the inclusion of perturbations in the dark energy comp...
