A multitracer study of a small aquifer in northern Switzerland indicates that the atmosphere in central Europe cooled by at least 5 degreesC during the last glacial period. The relation between oxygen isotope ratios (delta18O) and recharge temperatures reconstructed for this period is similar to the present-day one if a shift in the delta18O value of the oceans during the ice age is taken into ...

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 ...

background: to retrospectively describe imaging characteristics of liver metastases on fused fdg-pet/ mri data sets and to compare the diagnostic accuracy of mri and fused fdg-pet/mri data sets for the detection of liver metastases in patients undergoing systemic anticancer treatment. materials and methods: 43 oncological patients (mean age: 56+/- 11 years) were investigated by fdg-pet/ct and l...

pp/pep blends, because of different solubility factors, are incompatible. the aim of this research was to use pp-g-ma compatibilizer in a two-component blend. after preparing this compatibilizer in internal mixer and investigating different parameters on producing process, optimum compatibilization was obtained. pp/pet (60/40) blend fibers with different percentages of this compatibilizer in tw...
