Regional chemotherapy with floxuridine was undertaken in 50 patients (32 men and 18 women, mean age 57 years) with colorectal carcinoma with metastases only to the liver. In 25 patients (group I) the drug (0.2 mg/kg) was administered exclusively intr

The power of photocurrent spectroscopy to study the electronic properties of InAs/GaAs self-assembled quantum dots is described. From comparison of results from different samples it is shown that photocurrent provides a direct means to measure absorp

Photocurrent (PC) spectroscopy is employed to study several important aspects of the interband optoelectronic properties of InAs/GaAs self-assembled quantum dots (SAQDs). PC spectroscopy is first shown to be a highly sensitive, quantitative technique

In this paper we show how a tightly focused pump beam can be used to alter the local refractive index of the sample. This local variation acts as a scattering site, which enables resolution exceeding that of a conventional scanning microscope to be o

Segmental aplasias of the inferior vena cava, thrombosis of the vena cava, tumour infiltration (e.g. renal neoplasms via the renal vein) and external compression (e.g. large hepatic metastases) may produce similar radiomorphologic changes in chest x-

Sonography of the ankle joint is a simple method of exploring articular soft tissue. 100 patients with acute injury of the lateral ligaments were examined with a 7.5 MHz linear array transducer. Diagnostic criteria were haematoma and capsular deforma

Optical spectroscopy of a single GaAs–AlGaAs V-groove quantum wire is reported. Photoluminescence spectra are recorded over a five order-of-magnitude variation of incident laser power. With decreasing laser power, a continuous transition is observe
