Satellite dishes like this owned by Wood Television Corp. in Bowling Green, Ohio, receive broadcast signals and retransmit them through the cable to subscribers. Rural local governments tend to regulate cable television (CTV) far less effectively than suburban local governments. That is the major conclusion from a survey of 119 small municipal governments in Maryland. Rural governments need to ...
Actualmente, se ha identificado la necesidad de emprender acciones que faciliten conservación biodiversidad y recuperación áreas degradadas, al mismo tiempo promueva el desarrollo sostenible. El cultivo tejidos vegetales in vitro (CTV), permite producir un gran número individuos, en espacios reducidos. A través técnica semillas sintéticas (SS), CTV posibilita propagación ex situ recursos fitoge...
BACKGROUND An observational multi-institutional study has been conducted aimed to evaluate the inter-observer variability in clinical target volume (CTV) delineation among different radiation oncologists in radiotherapy treatment of pancreatic cancer. METHODS A multi-institutional contouring dummy-run of two different cases of pancreatic cancer treated by postoperative and preoperative radiot...
PURPOSE To compare planning target volume (PTV) defined by PET combined with 4DCT to 3DCT and 4DCT. METHODS Eighteen (18/30) esophageal cancer patients who underwent 3DCT, 4DCT and (18)F-FDG PET-CT thoracic simulation with SUVmax≥2.0 of the primary volume were enrolled. CTV3D was formed on 3DCT by adding a margin of 30 mm in cranial-caudal direction and 5 mm in transversal direction. PTV3D wa...
Purpose The aim of this study was to compare the implant quality between intraoperatively built custom-linked seeds (IBCL) and loose seeds (LS) retrospectively. Material and methods This study included 74 prostate cancer patients who were treated with permanent prostate brachytherapy (PPB) using IBCL (n = 37) or LS (n = 37) between July 2014 and June 2016. Dose-volume histogram (DVH) paramete...
PURPOSE Intensity modulated radiation therapy (IMRT) of head and neck tumors allows a precise conformation of the high-dose region to clinical target volumes (CTVs) while respecting dose limits to organs a risk (OARs). Accurate patient setup reduces translational and rotational deviations between therapy planning and therapy delivery days. However, uncertainties in the shape of the CTV and OARs...
Citrus tristeza virus (CTV) causes two citrus diseases that have caused devastating losses in global citrus production. The first disease is quick decline of trees propagated on the sour orange rootstock. The second disease is stem pitting, which severely affects a number of economically important citrus varieties regardless of the rootstock used and results in reduced tree growth and vigor as ...
