Original abstract

The content of solved problematics is the rolling of extewrnal threads by means of rolling heads. The thread is considered in the given case as costructional, technological element of components as for instant shaft, guiding thread and the others. . Thread rolling is in the solved case included into the production procedure in relation to the corresponding machining operation and is realized on the suitable machine tool. Threading rolling heads are constructed as fixed or rotating. Rolled threade demonstrate important improovement of functional parameters in comparison with the thread finished by cutting. This is due to the continuous corse of fibres, increased strenbht of thread profile, lower value of roughness. Conclusions of the contribution are generally specified by practical recommendations for their use during thread rolling in the production process of mechanical components.

Czech abstract

Here we report on quantitative Laser-Induced Breakdown Spectroscopy analysis to study the presence of trace minerals in teeth. We found a close link between elements detected in tooth fillings and toothpastes with those present in teeth.
