We evaluated humoral immunity by measuring IgG, IgA, IgM, and IgE concentrations in 274 male workers in an iron foundry in Cracow, Poland. There were two groups: 199 coke oven workers and 76 cold-rolling mill workers. The groups were similar with respect to age, length of work (average 15 years), and smoking habits. Exposure to polycyclic aromatic hydrocarbons (PAHs), assessed by personal and a...

The relevance of the study is proved by two factors. One them necessity to nature change in microstructure cross-section extra-thin tinplate made TS 435 steel (analogue 08ps steel) skin-passed a new DSR-1250 mill Miory Metal Rolling Plant. second factor need develop an effective method for obtaining accurate geometry characteristics oblique cut 0.19 mm or less thick. purpose work determine chan...

change in two stands of jack pine (Pinus banksiana Lamb.) and one stand of black spruce (Picea mariana (Mill.) B.S.P.) on relatively clear days from late May until mid-September 1994. Field measurements were made with a portable infrared gas analyzer, and laboratory measurements included photosynthetic oxygen evolution and needle chemical composition. Seasonally averaged light-saturated assimil...

The evolution of texture in the AlMg6Mn0.7 (1565 ch) alloy throughout entire cycle its thermomechanical treatment has been studied. Using this as an example, a new way is shown to control development, which applicable alloys with high magnesium content. An integrated approach applied, including optical and electron microscopy, well X-ray diffraction analysis, determination mechanical properties...

Sawmills require specific information on the volume, the number and the diameter classes of different types of log assortments that could potentially be cut from a stand which the mill intends to tender for or harvest. Knowledge of the consequences of adopting a particular cross-cutting strategy would also enable mills to identify the optimum combination of products to be harvested from a stand...

Flatness measurement using shape-rolls has been used in cold rolling mills for a long time. The benefit is obvious since the measured flatness profile can be used directly to control roll bending, tilt and cooling profile. It was therefore integrated in the mill control system at an early stage to control the strip shape against a target I-unit profile. However, since the flatness is also affec...

In the paper we rewiev the experience with the steel from Cold Rolling Mill Kraluv Dvur near Prague, where the steel for barrel module 0 prototype of the TILECAL calorimeter was fabricated. The measurements of the tolerances, mechanical properties and the chemical composition are presented.
