Dissimilar underwater wet welding of HSLA steels
PublicationThe high-strength low-alloy S460ML and S460N steels were chosen for underwater wet welding of dissimilar T-joints using covered electrodes. For improving the quality of joints, the temper bead welding (TBW) method was used. The application of TBW in pad welding conditions has been investigated earlier but the possibility of usage of this technique in welded joints was not analyzed. The main aim of the study was to check the influence...

Effect of MgSO4 nutrition on Theobroma cacao L. susceptibility to Phytophthora megakarya infection
PublicationA new strategy to reduce the severity of black pod disease (BPD) in T. cacao plants using MgSO4 nutrition was investigated. The dynamics of the tolerance to BPD of 18 susceptible T. cacao plantlets coming from the cross (♀SNK64 × ♂UPA14) was monitored during weekly (8 weeks) supply of MgSO4 into the soil. Prior to MgSO4 application, disease scores of the 18 plantlets (in six sets of three plantlets per set) were varying between...

INTERLABORATORY COMPARISON OF THE ELECTROMAGNETIC EMISSION MEASUREMENTS USING FAR AND GTEM TEST SITES UP TO 1 GHz
PublicationElectromagnetic emission limiting is one of the basic requirements in the European Directive 2014/30/EU (EMC Directive). Manufacturers often use alternative methods of measurements to make preliminary verification of emission. This paper presents and analyzes problem with comparison between measurements in different test sites: FAR (Fully Anechoic Room) and GTEM (Gigahertz Transverse Electromagnetic cell). FAR is assumed as the...

Determining and verifying the safety integrity level of the safety instrumented systems with the uncertainty and security aspects
PublicationSafety and security aspects consist of two different group of functional requirements for the control and protection systems. In the paper it is proposed that the security analysis results can be used as a factor increasing or decreasing the risk level. It concerns a process of determining required safety integrity level of given safety functions. The authors propose a new approach for functional safety risk analysis. In this case...
