OPTIMAL ORGAN-SPARING INTENSITY-MODULATED RADIATION THERAPY (IMRT) REGIMEN FOR THE TREATMENT OF LOCALLY ADVANCED ANAL CANAL CARCINOMA: A COMPARISON OF CONVENTIONAL AND IMRT PLANS

Abstract Background To compare the dosimetric advantage of three different intensity-modulated radiation therapy (IMRT) plans to a three dimensional (3D) conventional radiation treatment for anal cancer with regards to organs-at-risk (OAR) avoidance, including iliac bone marrow.Methods Five patients with T1-3 N0-1 anal cancer and five with T4 and/o

Today, offline programing is available on industrial manipulators and used in many factories.However, the absolute accuracy of robots is insufficient due to manufacturing and assembly tolerances, thus it is necessary to perform kinematic calibration in advance.Most of existing calibration methods require a large amount of measurements just to calib

Results of research of petrographic and mineralogical structure of alluvial meadow dark-coloured soils are Boys Swim resulted.Studying soil parts has allowed to receive the qualitative and quantitative characteristic of clay minerals.Their influence on physical properties is established.At an intensive irrigation of cultivated cultures mobili-satio

The Hyalomma species of ticks have gained additional attention due to their role in the transmission of Theileria annulata infection in animals and the Crimean-Congo Haemorrhagic Fever (CCHF) virus in humans.Apart from these, many other pathogens viz., Mobile Worktables other species of Theileria, a few species of Babesia, Rickettsia and viruses ar

Hermatypic, scleractinian corals are the most important benthic substrates in a coral reef ecosystem.The existing, high (spatial) resolution, broad-band, multi-spectral, space-borne sensors have limited capability to spatially detect and spectrally discriminate coral substrates.In situ hyperspectral signatures of eight coral targets were collected
