Objective(s): The aim of this study was to analyze detection rates and effectiveness of 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) cancer screening program for prostate cancer in Japan, which is defined as a cancer-screening program for subjects without known cancer. It contains FDG-PET aimed at detection of cancer at an early stage with or without additional screening tests ...

Introduction Environmental concerns in developing wind farms have been highlighted by both the wind-energy community and ecological experts [1–3] as the demand for wind power energy grows rapidly around the world to meet public policies for renewable energy. One of the primary concerns is the increase in bird mortality caused by collision with blades, loss of nesting and feeding grounds, and in...

Bird species’ community responses to land use in the suburbanizing Twin Cities, Minnesota, USA, were contrasted among reserves, rural lands, and suburbs. For each land use type, bird composition, diversity, and abundance were recorded for 2 years in 99 plots in three sampling units (each 4500 ha). A habitat gradient defined by canopy structure (grasslands to savannas to forests) was influenced ...

Demand for bioenergy is increasing, but the ecological consequences of bioenergy crop production on working lands remain unresolved. Corn is currently a dominant bioenergy crop, but perennial grasslands could produce renewable bioenergy resources and enhance biodiversity. Grassland bird populations have declined in recent decades and may particularly benefit from perennial grasslands grown for ...

پلی اتیلن ترفتالات (pet) از جمله پلیمرهایی است که در تولید پوشش های ضدمیکروبی کاربرد دارد. این پلیمر خطی بوده و در برابر حلال ها مقاوم می باشد. یکی از روش های ایجاد خاصیت ضد باکتری در محصولات پلی اتیلن ترفتالات تثبیت کیتوزان بر سطح این پلیمر می باشد. تثبیت عامل ضد باکتری با استفاده از پیوندهای کووالانسی بر سطح پلیمر هنگامی ممکن است که هم پلیمر و هم عامل ضد باکتری گروه های عاملی واکنش دهنده با ی...

introduction:  the  advent  of  dual-modality  pet/ct  scanners  has  revolutionized  clinical  oncology  by  improving lesion localization and facilitating treatment planning for radiotherapy. in addition, the use of  ct images for ct-based attenuation correction (ctac) decreases the overall scanning time and creates  a noise-free  attenuation  map  (6map).  ctac  methods  include  scaling,  s...

Abstract A simplified model of the bird skeleton along with elongation parameters for the flight feathers is used to explore the diversity of bird shapes. Varying the small number of parameters simulates a wide range of observed bird silhouettes. The model may serve to examine developmental factors involved in these forms, help museum curators develop computational approaches to bird morphometr...

Auditory expertise has mostly been studied in relation to musical processing, but expert auditory processing can also involve nonmusical auditory stimuli, such as birdsongs in bird experts. In this study, the neural correlates of bird expertise were investigated by using electroencephalography to measure auditory-evoked potentials in bird experts and novices. Auditory stimuli in three categorie...

Objective(s): Post-treatment evaluations by CT/MRI (based on the International Working Group/ Cotswolds meeting guidelines) and PET (based on Revised Response Criteria), were examined in terms of progression-free survival (PFS) in patients with malignant lymphoma (ML). Methods: 79 patients, undergoing CT/MRI for the examination of suspected lesions and whole-body PET/CT before and after therapy...
