COMSOL Multiphysics has been used to validate and check the design of a header transporting ammonia gases released from pressure safety valves (PSVs) to the tip of the flare. The header is part of a dedicated flaring system to contain emissions from ammonia storage tanks. The two main challenges are the low relief pressure and high capacity of the system. Another difficulty is the high relief ...

Introduction: We study an innovative technology for water bottling using PET, aimed at reducing the thickness of the plastic bottles. The goals are the reduction of the amount of plastic used for a single water bottle, the reduction of the packaging costs and more environmental sustainability. The required thickness of the bottle depends on its structural function: when carried, the bottles are ...

In 2010 an estimated 109 million infants were immunized against DTP, which serves as a good proxy for vaccinations in general. At the same time, however, approximately 19.3 million infants worldwide were not reached by routine DTP immunization services. Immunization rates tend to be lowest in areas where poor infrastructure and limited access to electricity can cause vaccine stock-outs and high ...

The technique of water calorimetry for primary-standard dosimetry of radiotherapy-level ionizing radiation is well established at national metrology institutes around the world, where such a direct realization of absorbed dose establishes the basis for calibrating instruments used for dosimetry in medical settings. The typical calorimeter system uses miniature thermistor beads to measure ...

The electromagnetic fields have a great influence on the behavior of all the living systems. The human body itself is a source of naturally generated electric and magnetic fields. When external signals of comparable strength flows through the human body; the nature of changes that such signals could induce in natural electrochemical processes and voltage is a subject of interest and of ...

Direct borohydride fuel cells (DBFCs) use sodium borohydride (NaBH4) as fuel and hydrogen peroxide (H2O2) as an oxidant. A mathematical model encompassing mass balance of ionic species in different regions of the DBFC is developed. Both the oxidation of sodium borohydride and reduction of hydrogen peroxide are assumed to obey Tafel kinetics. This is combined with boundary conditions ...

The alternative engines of Stirling type, are engines running on "hot air", using both an external heat source and regeneration. They should be considered as an alternative for the effective conversion of renewable energy sources into work, with their theoretical yield equal to the theoretical Carnot limit. The output efficiency and the power of these engines are strongly related to the ...

A state of permanent, isothermal nonwetting of a solid surface by a normally wetting liquid may be achieved by having the surface move tangentially to a liquid drop that is pressed against it. Surrounding gas is swept into the space between the liquid and solid creating a lubricating film that prevents wetting. The length scales of the drop and the film are typically three or more orders of ...

Modelling of pit chemistry in applied polarization mode is carried out using finite element method techniques (FEM). The results lead to the formulation of critical conditions for pit stabilization in terms of pit geometry and applied potential. More detailed computing is performed to compare the stability behaviour of both ferritic AISI 430 and austenitic AISI 304 stainless steels. The ...
