Comparison of Material Properties of Multilayered Laminates Determined by Testing and Micromechanics.

This paper presents an experimental material campaign focusing on fiber-reinforced polymers (FRP) to be applied in a novel bridge deck panel. Laminas based on most commonly used fibers, i.e.

Experimental Study on a Novel Shear Connection System for FRP-Concrete Hybrid Bridge Girder.

The study presents experimental results of an investigation on a novel shear connection system for hybrid bridge girders composed of laminated composite beams and concrete slabs. The special connector comprised of a steel plate and welded bolts is attached to beam's top flange by adhesive bonding and with a preset torque of nuts. The study's purpose is to check ductility, safety, reliability and robustness of the shear connection before its implementation in the first Polish composite bridge.

Month of birth and level of insolation as risk factors for multiple sclerosis in Poland.

Introduction: Many studies have shown that people born in the spring are at a higher risk of developing multiple sclerosis (MS). This may be associated with lower levels of sun exposure, and consequently, lower levels of vitamin D3 during pregnancy. However, these relationships have not been verified thus far in any countries in Central Europe.
