1. An Experimental Study of Submerged Entry Nozzles (SEN) Focusing on Decarburization and Clogging
Abstract : The submerged entry nozzle (SEN) is used to transport the molten steel from a tundish to a mould. The main purpose of its usage is to prevent oxygen and nitrogen pick-up by molten steel from the gas. Furthermore, to achieve the desired flow conditions in the mould. READ MORE

2. Effects of Vagus Nerve Stimulation and Ketogenic Diet on Quality of Life and Changes in EEG and Sleep
Abstract : When anti-epileptic drugs fail, and epilepsy surgery is found unfeasible or ineffective, there remains a group of at least 25% of children with epilepsy in whom seizure control cannot be achieved. Vagus nerve stimulation (VNS) is an adjunctive treatment for medically refractory epilepsy. READ MORE

3. The rule of hydrogen and rare earth metals in the formation of protective metal-oxides
Abstract : The effects of hydrogen and rare earth metal (REM) additionson the oxidation behavior of metals and alloys that formchromia, alumina and zirconia in 20 mbar O2and/or H2O have been investigated at elevated temperatures.The metal-gas reactions were studied by the use of isotopicallylabeled gas in combination with mass spectrometry and bymeasuring changes in the total pressure in a closed reactionchamber.

4. A study on the Submerged Entry Nozzels (SEN) respecting clogging and decarburization
Abstract : The submerged entry nozzle (SEN) has been used to transport the molten steel from tundish to the mould. The main purpose of the SEN usage is both to prevent oxygen and nitrogen pick-up by molten steel and to achieve the desired flow condition in the mould. READ MORE

5. Influence of the electrolyte on the electrode reactions in the chlorate process
Abstract : The chlorate process is very energy intensive and a major part of the production costs are for electrical energy. Since the electricity prices are constantly increasing and may also vary periodically, the chlorate plants may be forced to adjust their production rate to the price at each moment in order to minimise their costs.
