The primary challenge in thermal ablation of liver tumors (e.g. hepatocellular carcinoma and hepatic colorectal cancer) is the relatively high recurrence rate (~30%) for which incomplete ablation at the periphery of the tumor is the most common reason. In an attempt to overcome this, we have developed a novel thermal accelerant (TA) agent capable of augmenting microwave energy from a distance n...

The mass of the W boson has been measured by the Lep collaborations from the data recorded during the Lep2 programme at e + e − centre of mass energies from 161 to 209 GeV, giving the result : MW = 80.450 ± 0.039 GeV/c 2. This paper discusses the measurements of the W Mass from direct reconstruction of the invariant mass of the W + W − decay products, particular emphasis is placed on the evalua...

Tidal power can play a vital role in integrating as new source of renewable energy to the off-grid power connection in isolated areas, namely Sandwip, in Bangladesh. It can reduce the present energy crisis and improve the social, environmental and economic perspective of Bangladesh. Tidal energy is becoming popular around the world due to its own facilities. The development of any country large...

α-fe2o3 (hematite) is the most stable iron oxide under ambient conditions. this transition metal oxide has been extensively investigated because it has unique electrical and catalytic properties. in this report, a novel microwave method for preparation of α-fe2o3 nanoparticles has been developed. the process contained two steps: first, precursor were obtained from a mixed solution of 50 ml of 0...

Aluminum metal matrix composites (AMMCs) are light-weight materials having wide-spread use in the automobile and aerospace industries due to their attractive physical and mechanical properties. The promising mechanical properties of AMMCs are ascribed to the size and distribution of the reinforcement, as well as to the grain size of the matrix. Microwave rapid sintering involves internal heatin...

Gas-liquid chromatography retention indexes for organic molecules are determined by the interaction between the molecule and the column liquid phase. In this article, a model for calculating the interaction energy between a molecule and a dielectric wall is developed. The model is at least to our knowledge the first attempt to predict retention indexes from the interaction between the molecules...

Microwave technology has been developed primary for communication and some areas of processing such as cooking food, thawing, and curing wood and rubber. As a heat source, microwaves allow a sample to be irradiated instantly with an associated rapid heating rate. Moreover, microwaves offer a number of advantages over conventional heating such as non-contact heating (reduction of overheating of ...

background and aims. current chemical methods may not efficiently disinfect dental stone casts. the aim of this study was to investigate if microwave irradiation is effective for disinfection of stone casts. materials and methods. in this laboratory study, three groups (n = 162) of prepared spherical stone beads as carriers with a diameter of 10 mm were inoculated by separately soaking in three...

background : widespread use of x-band frequency (a part of the super high frequency microwave) in the various workplaces would contribute to occupational exposure with potential of adverse health effects.  according to limited study on microwave shielding for the workplace, this study tried to prepare a new microwave shielding for this purpose. methods: we used ei-403 epoxy thermosetting resin ...

This study evaluated water sorption in heat-polymerized acrylic resins processed in monomaxillary flasks by water bath and in bimaxillary flasks by microwave energy and water bath. Fifty heat-polymerized acrylic resin specimens were fabricated according to the 12th specification of the American Dental Association and assigned to 3 groups: group 1 was processed by water bath in monomaxillary met...
