Introduction The increasing practice of interventional fluoroscopy in diagnosis and treatment of cardiovascular disease has risen attention to improve radiation protection of patients and cardiologists in these relatively high dose techniques. Therefore, nowadays there is an emphasis on the measurement of radiation dose received by patients and cardiologists arising from the relevant procedures...

Accuracy of the radiotherapy requires some routine quality control and dosimetry calculations, which would be done by radiotherapy physicists. Due to the increasing use of computers and simulation software in medical science, as well as trends indicating its continued growth, this study aims to develop a new smart-phone application to perform common radiotherapy-related calculations. Computatio...

introduction magnetic fields are capable of altering the trajectory of electron beams andcan be used in radiation therapy.theaim of this study was to produce regions with dose enhancement and reduction in the medium. materials and methods the ndfeb permanent magnets were arranged on the electron applicator in several configurations. then, after the passage of the electron beams (9 and 15 mev va...

an experiment was conducted to evaluate the efficacy of clopyralid mixed with other herbicides weeds and sugar beet (beta vulgaris) in 2008 at experimental field of research center of agricultural and natural resources research center of khorasan razavi. experimental design was completely randomized block with three replications. treatment were included doses of 350 and 500 ml.ha-1 clopyralid i...

background: the purpose of this study was to investigate the application of the monte carlo technique to calculate and analysis of dosimetric parameters for electron beams used in radiotherapy. this technique is based on statistical method and has a powerful role in different radiotherapy aspects. materials and methods: the simulated medical linear accelerator was the varian clinac 2100c. the e...

3.1: Treatment of the initial episode of SSNS 3.1.1: We recommend that corticosteroid therapy (prednisone or prednisolone)* be given for at least 12 weeks. (1B) 3.1.1.1: We recommend that oral prednisone be administered as a single daily dose (1B) starting at 60 mg/m/d or 2 mg/kg/d to a maximum 60 mg/d. (1D) 3.1.1.2: We recommend that daily oral prednisone be given for 4–6 weeks (1C) followed b...

Abstract Numerous studies have demonstrated that soil applications of biochar contribute to plant disease suppression and growth promotion. Here, we quantitatively evaluated the performance biochars on production using meta-analysis literature data. The results indicated amendment dramatically reduced severity (DS) by 47.46% while increasing biomass 44.05%. highest was achieved with application...

Estimation of the genetic hazards of ionizing radiation in men is based largely on the frequency of transmitted specific-locus mutations induced in mouse spermatogonial stem cells at low radiation dose rates. The publication of new data on this subject has permitted a fresh review of all the information available. The data continue to show no discrepancy from the interpretation that, although m...
