we present a rare case with history of neurological symptoms due to multiple brain metastases and no urological symptoms. during patient evaluation for primary tumor, transitional cell carcinoma (tcc) of left renal pelvis was found. the patient underwent gamma knife stereotactic radio-surgery for the metastatic brain lesions. radical nephroureterectomy was performed, and a 4-cycle course of pac...

background: cigarette smoking is one of the most important health‑related risk factors in terms of morbidity and mortality. in this study, we introduced a new method for deriving the transitional probabilities of smoking stages from a cross‑sectional study and simulated a long‑term smoking behavior for adolescents. methods: in this study in 2010, a total of 4853 high school students were random...

Diffusion technique of metallization is applied for receiving zinc coatings on low-carbon steel with transitional zone. Structure diffusion layers after saturation 09Mn2Si in ammonia at different temperatures examined. Effects temperature thickness are discovered. Process 600⁰C forms high strengthening level and smooth microhardness profiles. Elements (Fe, Zn, N) spectrums analyzed, phase compo...

Metallic phases in the Tazewell IIICD iron and Esquel pallasite meteorites were examined using 57Fe synchrotron Mössbauer spectroscopy. Spatial resolution of ~10-20 μm was achieved, together with high throughput, enabling individual spectra to be recorded in less than 1 h. Spectra were recorded every 5-10 μm, allowing phase fractions and hyperfine parameters to be traced along transects of key ...

Single and multi-phase numerical simulations are carried out to investigate the heat transfer and entropy generation behaviour of transitional flow of TiO2 H2O nanofluid in a circular pipe. Results reveal that the small diameter of nanoparticles has the highest heat transfer rate for χ = 6% and the TiO2-water nanofluid shows higher heat transfer rate using multi-phase model compared to that of ...

The bacteria metabolic process of open nonlinear dissipative system far from equilibrium point is modeled using classical methods synergetics. invariant measure and its convergence in the phase space was obtained strange attractor mode. distribution density trajectory intersection cells with maximum time average value obtained. result concluded that an can be a characteristic transitional adapt...

BACKGROUND Among hospitalized older adults who transfer to skilled nursing facilities (SNF) for short stays and subsequently transfer to home, twenty two percent require additional emergency department or hospital care within 30 days. Transitional care services, that provide continuity and coordination of care as older adults transition between settings of care, decrease complications during tr...
