The Plateau Numerical Weather Forecast System (GY-WRF) was evaluated for its ability to forecast spring weather in Danghe South Mountain. forecasted temperature, relative humidity, and wind were compared with GRAPES using data from four automatic stations March April 2022. results showed that GY-WRF had the smallest mean absolute error (MAE) each factor at station 4, a small MAE speed 2, but sl...
Dose responses were compared among primary lung tumors and their histological types induced by a single inhalation exposure of female Wistar strain rats to submicron-size and polydispersed aerosols of plutonium dioxide (239PuO2). While the primary lung tumors were found only in 2.3% of the unexposed control animals, the frequency of all the primary lung tumors in the exposed animals was 44% at ...
The effects of carbon-ion irradiation and X-irradiation on the development of rat brain were compared. Twenty pregnant rats were injected with bromodeoxyuridine (BrdU) at 9 pm on day 18 of pregnancy and divided into five groups. Three hours after injection (day 19.0) one group was exposed to 290 MeV/u carbon-ion radiation by a single dose of 1.5 Gy. Other groups were exposed to X-radiation by 1...
1. Ordered groups. Suppose T is a simply ordered set and for each 7 in T let Ry be an additive group. Consider the set H = H(T, Ry) of all vectors ( • • • , ry, ■ • • ) for which ry is in Ry and almost every r"< is zero (i.e., the set of 7's for which ry^0 is inversely well ordered). H is a group w.r.t. (with respect to) vector addition, called the T-sum of the Ry. It the Ry are ordered groups ...
The focus of the study is an intercomparison of laboratories' dose-assessment performances using the cytokinesis-block micronucleus (CBMN) assay as a diagnostic triage tool for individual radiation dose assessment. Homogenously X-irradiated (240 kVp, 1 Gy/min) blood samples for establishing calibration data (0.25-5 Gy) as well as blind samples (0.1-6.4 Gy) were sent to the participants. The CBM...
Purpose: The purpose of this study is to analyze and compare the dosimetric parameters of three dimensional conformal radiotherapy (3DCRT) and intensity modulated radiotherapy (IMRT) in selected non-small cell lung cancer (NSCLC) cases. Methods: Ten patients with inoperable NSCLC were selected for this study. The 3DCRT and IMRT plans were generated for all patients following Radiation Therapy O...
PURPOSE Radiation therapy plays an essential role in the treatment of locally advanced lung cancer, but it inevitably leads to incidental and unnecessary dose to critical organs, including the lung, heart, and esophagus. Numerous radiation dose-volumetric parameters have been associated with increased risk of morbidity and mortality. The purpose of the present study is to quantify differences i...
Traditionally, as a standard dose fractionation schedule, adjuvant radiotherapy for breast cancer has been performed using prescribed doses of 46–50 Gy divided into daily fractions 1.8–2 Gy. Overall, treatment took 5 weeks. In the 1990s, schedules higher (2.5–3 Gy), smaller number (hypofractionation), and reduced overall started in context clinical trials. First results revealed an equivalent c...
