Salting in

In Africa, as in other parts of the world, civilization emerged in areas where farming was mastered. Some African civilizations later became wealthy by trading ivory, gold, iron, salt, and other goods. Migration and the spread of Islam were also important in the development of African societies.

This study focuses on the stability of nano-emulsions produced by phase inversion temperature method using n-Decane and n-Dodecane as the dispersed phase and pure water/brine as the aqueous phase (continuous phase). A non-ionic surfactant (Brij 30) was used in the preparation of the nano-emulsions. Three different types salt namely \(NaCl\), \(KCl\) and \(MgC{l_2}\) were used at different concentrations.

The aim of this study is to explore and develop methods of controlling colour while overcoming many of the inherent problems in the processing. Because to the enormous variety of paper available, testing for printing was narrowed to primarily 100% cotton papers. The negative was critical in realising the full potential of the salt prints tonal range. The film tested was limited by availability in the Australian market. The research into various films to create digital output negatives proved to be complex and time consuming.

Effect of the [U(IV)/U(III)] ratio of fuel salt on selective chromium corrosion and tellurium intergranular cracking (IGC) of Hastelloy N alloy in the LiF-BeF2-UF4 salt mixture was investigated. The chromium corrosion of Hastelloy N alloy is caused by the oxidation of chromium on the alloy surface by reaction with UF4.

The final goal of the work is to provide useful recommendations and guidelines for the design of a cold plug for the emergency draining system of a molten salt reactor. Some numerical thermal simulations were performed with ANSYS mechanical (Finite Element Method) to be compared with results of the experiments and to make extrapolations for a new component to be used in a reactor.

A key feature of molten salt reactors is the possibility to reconfigure the fuel geometry (actively or passively driven by gravitational forces) in case of accidents. In this regard, the design of reference molten salt reactor of Generation IV International Forum, the MSFR, foresees the Emergency core Draining System (EDS).

The goal of this study is to demonstrate and quantify the impact that the uncertainty in thermophysical properties has on key metrics of thermal hydraulic importance for MSRs, in particular on the heat transfer coefficient. In order to achieve this, computational fluid dynamics (CFD) simulations using the RANS k-ω SST model were compared to published experiment data on molten salt.
