A small and robust dosimeter for determining the biologically effective dose of ambient UV radiation has been developed using UV-sensitive mutant spores of Bacillus subtilis strain TKJ6312. A membrane filter with four spots of the spores was snapped to a slide mount. The slide was wrapped and covered with two or more layers of polyethylene sheet to protect the sample from rain and snow and to r...
BACKGROUND Evaluating residency programs requires objective assessment tools, but few are readily available. The purpose of this study was to measure education by correlating resident test scores with several measurements of educator performance. MATERIALS AND METHODS The study group included residents and educators from a single residency program. We performed a retrospective analysis of sco...
Soybean rust (SBR) in Brazil is controlled with fungicides, which have shown variable, sometimes declining, efficacy over time. A Monte Carlo simulation framework was implemented as a decision tool and to estimate the probability for fungicide programme being profitable depending on total cost defined by user. Probability distributions were fitted slopes intercepts of disease–yield relationship...
OBJECTIVE The aim was to formulate practice guidelines for endocrine evaluation and treatment of pituitary incidentalomas. CONSENSUS PROCESS Consensus was guided by systematic reviews of evidence and discussions through a series of conference calls and e-mails and one in-person meeting. CONCLUSIONS We recommend that patients with a pituitary incidentaloma undergo a complete history and phys...
BACKGROUND Assumptions about the damaging effects of radiotherapy (XRT) are based on studies in which total dose, dose fraction, treatment volume, degree of malignancy, chemotherapy, tumor recurrence, and neurologic comorbidity interact with XRT effects. This is a prospective, long-term study of XRT effects in adults, in which total dose and dose fraction were constrained and data related to tu...
OBJECTIVE The development of computed tomography (CT) and magnetic resonance imaging (MRI) has resulted in the discovery of unsuspected endocrinologically silent pituitary masses (pituitary incidentalomas). The aim of this study was to perform a national survey on pituitary incidentalomas in order to establish an appropriate approach to them. DESIGN AND METHODS Five hundred and six patients w...
Wheat is the main focus of the economy of Kurdistan province in which the annual fluctuation of wheat yield is 4/11 times as affected by the climatic elements of the site. This study investigated the role of agro-climatic variables and indices on rainfed wheat yield in Kurdistan province. The data of planting area, amount of production, damages and yield of wheat of 31-year in 10 regions of Kur...
