Using a laser velocity interferometer, wave profiles were recorded in porous (porosity 30%) nickel aluminide samples. Data on shock compressibility obtained. An abnormally high compaction was found, manifested the intersection of Hugoniots solid and samples at pressure 28 GPa, which indicates phase transition. Keywords: waves, Hugoniot, transitions, Doppler interferometers, intermetallides.

background : the brain is a rare site of metastases from ovarian cancer. limited data are available on prognostic factors, standard treatment, and survival. knowledge of clinical prognostic factors would help the management of patients with brain metastases. the aim of this study is to evaluate the impact of clinical factors and treatment modalities on survival in patients with brain metastases...

The article deals with the effect of irradiation Si+ ions on phase transformations in Ti–Al system during thermal annealing. An aluminum film a thickness 500 nm was deposited VT1-00 titanium samples by magnetron sputtering, followed ion implantation. Samples before and after Si were annealed vacuum 10?4 Pa temperature range 600–1000 °C. It established that implantation reduces dissolution Al ?-...

BACKGROUND Ovarian cancer is the fifth most common cancer in the UK, and the fourth most common cause of cancer death. Of those people successfully treated with first-line chemotherapy, 55-75% will relapse within 2 years. At this time, it is uncertain which chemotherapy regimen is more clinically effective and cost-effective for the treatment of recurrent, advanced ovarian cancer. OBJECTIVES ...

OBJECTIVES Assessment of level of exposure to platinum and platinum concentration in urine from platinum industry workers to evaluate internal exposures and excretion kinetics. METHODS Platinum concentrations in urine samples from 34 workers were measured by adsorptive voltammetry after UV-photolysis. Morning and evening samples were taken two to six times during six months. Individual exposu...

BACKGROUND The aim of this study was to evaluate long-term platinum retention in patients treated with cisplatin and oxaliplatin. METHODS 45 patients, treated 8-75 months before participating in this study, were included. Platinum levels in plasma and plasma ultrafiltrate (pUF) were determined. In addition, the reactivity of platinum species in pUF was evaluated. Relationships between platinu...
