background: defects in b cell class switch recombination (csr) are a heterogeneous and yet very uncommon group of disorders which all have a genetic basis uniformly leading to hyper igm (higm) syndrome. due to the rare frequency of these conditions, a very small number of case series have been conducted on the affected patients. objective: to shed some light on the morbidity and mortality regar...

Effects of four cooking methods (microwave cooking, grilling, steaming and shallow fat frying) and reheating by microwave on volatile profile in S. commerson were evaluated. Thirty compounds were identified in GC-MS analysis of raw samples. The number of volatile compounds had increased to 36, 46, 45 and 45 compounds in microwave cooked, grilled, steamed and shallow fat fried samples, respectiv...

The broad bandwidth and low loss offered by modern photonics have led to an ever-increasing interest in the design and implementation of photonically assisted solutions for the generation, processing, control and distribution of microwave signals, an area called microwave photonics. In this article, a tutorial on microwave photonics is presented with an emphasis on optical generation of microwa...

salmonella     species show different disease syndromes and host specificity, according to their antigenic profile. salmonella enterica serovar typhimurium is one of the most frequently isolated serovar from foodborne outbreaks. poultry meat has been identified as one of the principal foodborne sources of salmonella. in this study, the effect of microwave treatment of chicken meat samples wh...

dehydration, as one of the practical ways to increase the shelf-life and applicability of yoghurt in various foodstuffs, is normally done by freeze drier (fd) which is an expensive and time-consuming process. for these reasons, in the present study the capability of microwave–vacuum drier (mvd), as an alternative process, was investigated. for doing so, the fat free yoghurt samples of 2.2, 4.2 ...

drying characteristics of green pea (pisum satium) with an initial moisture content of 76% (db) was studied in a fluidized bed dryer assisted by microwave heating. four drying air temperatures (30, 40, 50 and 60ºc) and five microwave powers (180, 360, 540, 720 and 900w) were adopted. several experiments were conducted to obtain data for sample moisture content versus drying time. the results sh...

a method to quick detect concentration of lecithin in eggs, namely microwave digestion spectrophotometry, was established in this research. the homogenate of eggs was treated with absolute ethanol to eliminate phosphate protein in eggs which could possibly affect concentration of lecithin examined. a sample then received a new way of pre-treatment, called microwave digestion, before uv-vis spec...

Many of the emerging broadband wireless access systems operate at mm-wave frequencies where large allocations of spectrum are available. GaAs Monolithic Microwave Integrated Circuits (MMICs) offer a means of realising low cost, high performance, high volume, reproducible mm-wave components. This paper details two Single Pole 4 Throw (SP4T) switch MMICs covering 24 to 34GHz and 34 to 45GHz. The ...

The microwave absorbing characteristics of magnetic separation products (magnetic and non-magnetic) of reductive products of ilmenite concentrate were measured by the method of microwave cavity perturbation and the magnetic separation products were characterized by X-Ray Diffraction (XRD). It was demonstrated that metallic iron was a strong microwave absorbing material, while TiO2 was a weak mi...
