INTRODUCTION Increased acceptance of nutrition benefits at farmers markets could improve access to nutritious foods for low-income shoppers. The objective of this study was to evaluate a pilot project to increase participation by farmers markets and their vendors in the Supplemental Nutrition Assistance Program (SNAP) and Special Supplemental Nutrition Program for Women, Infants, and Children (...
PURPOSE We present a framework, in which we compare a conventional standard dose of 50 Gy in 25 fractions with accelerated partial breast irradiation (APBI) using electronic brachytherapy (eBT). We discuss how radiobiological modelling enables us to establish a framework, within which we can compare external beam radiotherapy (EBRT). This leads to a determination of the shell of isoeffect in br...
در این کار تحقیقی یک روش جدید، موثر، گزینش پذیر و بسیار ساده برای تشخیص کاتیون نیکل و آنیون سیانید در محدوده وسیعی از آنیون ها f-، cl-، br-، i-، ch3coo-، h2po4-، scn-، no3-، co32-، c2o42-، so32- با روش رنگ سنجی که به صورت گزینش پذیر عمل می کند گزارش می شود. رفتار اریو کروم بلک تی (ebt)، لیگاند رنگزایی که به راحتی در دسترس است، به عنوان یک گیرنده شیمیایی رنگ سنجی در حضور جزءهای کاتیون فلزی و آنی...
Since 1997, linac based stereotactic radiotherapy (SRT) of uveal melanoma has been continuously developed at the Department of Radiotherapy, Medical University Vienna. The aim of the present study was (i) to test a new type of radiochromic film (Gafchromic EBT) for dosimetric verification of class solutions for these treatments and (ii) to verify treatment plan acceptance criteria, which are ba...
مقطع نگاری عرضی کامپیوتری(ct-scan) یکی از روشهای تصویربرداری است که در آن با استفاده از پرتو ایکس تصاویر مقطعی از بدن با تباین (کنتراست) و تفکیک پذیری (رزولوشن) بالا به دست میآید. با این حال پرتودهی ناشی از آزمونهای مقطع نگاری عرضی کامپیوتری نسبت به سایر روشهای تصویربرداری باعث انتقال دز بیشتر به افراد میشود. هدف از این مطالعه ارزیابی نحوه توزیع دز در یک فانتوم معادل بافتاز جنس پلی متیل مت...
OBJECTIVE Heart failure (HF) continues to be a leading cause of hospital admissions, particularly in underserved patients. We hypothesised that providing individualised self-management support to patients and feedback on use of evidence-based HF therapies (EBT) to physicians could lead to improvements in care and decrease hospitalisations. To assess the feasibility of conducting a larger trial ...
We present observations of the center of the Galactic globular cluster NGC 6273, obtained with the HST/WFPC2 camera as part of the snapshot program GO-7470. A B, V color–magnitude diagram (CMD) for ∼28,000 stars is presented and discussed. The most prominent feature of the CMD, identified for the first time in this paper, is the extended horizontal branch blue tail (EBT) with a clear double-pea...
Radiochromic films are important tools for assessing complex dose distributions. Gafchromic EBT-XD films have been designed for optimal performance in the 40-4,000 cGy dose range. We investigated the dosimetric characteristics of these films, including their dose-response, postexposure density growth, and dependence on scanner orientation, beam energy, and dose rate with applications to high-do...
PURPOSE The use of radiation therapy (RT) for non-melanoma skin cancer (NMSC) has been changing throughout the last century. Over the last decades, the use of radiotherapy has surged with the development of new techniques, applicators, and devices. In recent years, electronic brachytherapy (eBT) devices that use small x-ray sources have been introduced as alternative to radionuclide dependence....
