Laser-induced breakdown spectroscopy for 24/7 automatic liquid slag analysis at a steel works.

Laser-induced breakdown spectroscopy (LIBS) is applied for the inline analysis of liquid slag at a steel works. The slag in the ladle of a slag transporter is measured at a distance of several meters during a short stop of the transporter. The slag surface with temperatures from ≈600 to ≈1400 °C consists of liquid slag and solidified slag parts.

Application of LIBS to the in-line process control of liquid high-alloy steel under pressure.

A process optimization and control system called VAI-CON Chem has been developed that uses laser-induced breakdown spectroscopy (LIBS) to quasi-continuously chemically analyze liquid high-alloy steel under pressure. The beam from a Nd:YAG laser, located on safe ground and operating at its fundamental wavelength, is guided by a mirror system to a process tuyere below bath level. Passing through the approximately 1.

Does overweight impact on the prognosis of patients with renal cell carcinoma? A single center experience of 683 patients.

Background And Objectives: An increased incidence of renal cell carcinoma (RCC) in obese patients has been reported by several authors. We investigated the association of body mass index (BMI) with prognosis of patients with RCC.

Methods: From January 1994 to December 2000, 693 operations for RCC in 683 consecutive patients were performed at our institution.

Selenium levels of patients with newly diagnosed prostate cancer compared with control group.

Objectives: To compare the toenail selenium level of patients with prostate cancer with that of controls. A tumor-protective effect of selenium has been discussed for many years. Published data about the influence of the selenium level in the plasma and toenails are controversial.
