A broadband microwave interferometric technique for scanning near-field microscopy applications is proposed. The method is based on the association of a vector network analyzer, a hybrid coupler, an evanescent microwave coaxial probe and a precise impedance tuner built up with a high precision programmable delay line and a variable motor-driven attenuator. Advantages such as simplicity of opera...

False alarm and misdetected precipitation are prominent drawbacks of high-resolution satellite precipitation datasets, and they usually lead to serious uncertainty in hydrological and meteorological applications. In order to provide accurate rain area delineation for retrieving high-resolution precipitation datasets using satellite microwave observations, a probabilistic neural network (PNN)-ba...

In this paper the evaluation of the dry, wet and microwave digestion methods applied on certified bovine liver (CRM 12-02-01) has been performed. The microwave digestion method was selected and validated for the copper, manganese and zinc determination in liver samples by FAAS, because it is simple, rapid (digestion was done in 2.5 hours, with reduced chemical use) and reliable. Furthermore, mi...

We demonstrate a detection method for microwave spectroscopy on magnetization reversal dynamics of nanomagnets. Measurement of the nanomagnet anisotropic magnetoresistance was used for probing how magnetization reversal is resonantly enhanced by microwave magnetic fields. We used Co strips of 2 μm × 130 nm × 40 nm, and microwave fields were applied via an on-chip coplanar wave guide. The method...

Microwave-assisted dilute acid/alkali pretreatment is an efficient and rapid method of removing lignin and hemicellulose, however, the optimized parameters for the maximum efficiency have to date not been presented in the literature. The purpose of this study was to determine those conditions by examining the effects of three factors: microwave power, temperature, and time on delignification in...

BACKGROUND Microwave irradiation has been tried as a replacement for the conventional tissue processing technique in histopathology laboratories for quite some time. Studies have shown that Domestic Microwave Tissue Processing (DMWTP) provides a faster delivery of the tissue sections with a morphology which is similar to that which is seen Conventional Tissue Processing (CTP). But many laborato...

BACKGROUND Limb-salvage surgery has been well recognized as a standard treatment and alternative to amputation for patients with malignant bone tumors. Various limb-sparing techniques have been developed including tumor prosthesis, allograft, autograft and graft-prosthesis composite. However, each of these methods has short- and long-term disadvantages such as nonunion, mechanical failures and ...
