Workers in the Arctic open-pit mines are exposed to harsh weather conditions. Employers are required to provide protective clothing for workers. This can be the outer layer, but sometimes also inner or middle layers are provided. This study aimed to determine how Arctic open-pit miners protect themselves against cold and the sufficiency, and the selection criteria of the garments. Workers' cold...

Preface This thesis was submitted in conformity with the requirements for the degree of Master of Science (MSc) in Civil Engineering. The preparation and evaluation of the experiments were performed at Royal Boskalis Westminster nv. The experiments have been carried out at the Fluid Mechan-I want to thank him for guiding me through the total process of this research. During this graduation work...

Crystalline arrays of proteinaceous subunits forming surface layers (S-layers) are now recognized as one of the most common outermost cell envelope components of prokaryotic organisms. The surface layer protein of Lactobacillus acidophilus ATCC4356 is composed of a single species of protein of apparent molecular weight of 43-46 KDa. Considering the Lactobacillus acidophilus ATCC4356 having the ...

Dual boundary element method-based numerical investigations are carried out on the wave reflection, transmission, and dissipation characteristics of a breakwater made porous cage filled with rocks. To assess hydrodynamic performance, we analyzed three different configurations (namely conventional trapezoidal shape, rectangular, inverted trapezoidal) by keeping volume rocks fixed for all configu...

The discharge properties and chemical surface stability of CeO2 containing Sr (CeSrO) as the candidate for high-γ protective layer of noble plasma display panels (PDPs) are characterized. CeSrO films have superior chemical stability, because of the decrease in reactiveness on surface due to their fluorite structure. The discharge voltage is 50 V lower than that of MgO films for a pure discharge...

This paper presents the new boundary condition implemented in the LNEC (Laboratório Nacional de Engenharia Civil) SPH (Smoothed Particle Hydrodynamics) numerical model based on the SPHysics model and on a standard SPH formulation: This piston-type wave-maker now includes dynamic wave absorption and allows the simulation of a semi-infinite flume. Verification of the active wave-maker absorption ...

This paper considers the history of oscillating water column (OWC) systems from whistling buoys to grid-connected power generation systems. The power conversion from the wave resource through to electricity via pneumatic and shaft power is discussed in general terms and with specific reference to Voith Hydro Wavegen's land installed marine energy transformer (LIMPET) plant on the Scottish islan...

The analysis and presentation of plan view parameters for 39 marinas operating in Croatia is made in the paper to enhance improvement of the spatial and economic planning of nautical tourism in Croatia. The following plan view parameters were collected: number of berths, number of dry berths, breakwater length, fixed pier length, pontoon length, waterfront length, water basin area, territory ar...
