magnetic field effects on the elastic response of polymeric piezoelectric cylinder reinforced with carbon nanotubes (cnts) is studied. the cylinder is subjected to internal pressure, a constant electric potential difference at the inner and outer surfaces, thermal and magnetic fields. the mori-tanaka model is used for obtaining the equivalent material properties of the cylinder. based on the ch...

In the field of microwave hyperthermia, the use of minimally invasive applicators is recognized as a very promising technique for the treatment of small tumours because a very thin applicator can be easily introduced inside the body and precisely localized using the most advanced 3D imaging techniques and surgical robots. Minimally invasive hyperthermic applicators (MIHA) have been successfully...

By the early 1950s, after its discovery and implementation in medicine, brachytherapy (BT) had become a wellestablished modality of treatment.. As it is today, intracavitary brachytherapy (ICBT) was used to deliver most of the central tumor dose for cervical cancer [1]. Because of the developments in external beam radiotherapy, allowing delivery of doses to deep tumors competitive with those ac...

  BEBIG Ruthenium-106 ophthalmic plaques have been used for treatment of uveal melanoma, retinoblastoma, melanoma of the iris and other special applications for many years. The plaques consist of a thin film of 106Ru, a beta emitter, encapsulated in pure silver. The present work proposes a new mathematical eye model for ophthalmic brachytherapy dosimetry. This new mod...

This problem was suggested by Bradley Klee. For the related case of one cylinder rolling inside another, see [1]. When one cylinder is directly above the other, we define the line of contact of the lower cylinder, 1, with the horizontal plane to be the z-axis, at x = y = 0. Then, the condition of rolling without slipping for the lower cylinder is that when it has rolled (positive) distance x1, ...

Method 65 patients awaiting cataract extraction were admitted to hospital on the day before operation. None of them had any topical or systemic treatment before or after admission. In each case, both eyes were white and quiet and the naso-lacrimal ducts were patent. At the time of admission, conjunctival swabs were taken from the lower fornix of each eye on dry, sterile cotton-wool applicators,...

Medical applications of microwaves (i.e., a possibility to use microwave energy and/or microwave technique and technology for therapeutical purposes) are a quite new and very rapidly developing field. Microwave thermotherapy is being used in medicine for cancer treatment and treatment of some other diseases since early eighties. This paper is a contribution to a theory of phase array applicator...
