In this report we are going to discuss ladle treatment, deoxidation procedure, reoxidation, etc. To live in present day competition and to have the ability of offering the consumers competitive prices, it is suitable to reduce the ladle treatment and still have a high quality of the product. In an effort to decrease the ladle treatment under these restrictions, quicker deoxidation procedure is demanded.
Silica-based membranes are regarded as promising way of hydrogen separation at elevated temperatures because of their high H2 permeance, excellent selectivity and relative ease to scale up. This really is particularly relevant because of their applications in coal gasification and steam reforming
In object to measure the physico-chemical speciation of iron, water samples were taken at 4 m depth during a spring bloom in Ekhagen Bay, Baltic Sea. Sampling was performed at 6 dates between March 18th and June 2nd year 2003. Cross flow
Application of adsorption processes for air purification requires an approach, which accounts for the presence of humidity. Four separate but related studies are conducted to examine the adsorption processes. A new pure component adsorption isotherm is developed to describe Type 5 adsorption.

This thesis gives a structural description of wetlands and some processes that are vital for the treatment of metal-polluted waters in wetlands. A number of factors affecting the productivity and useful lifetimes of treatment wetlands are also described. The sources of acid
It has been long established that Reynolds number effects can lead to flow instabilities and/or transition from laminar to turbulent flow regimes. The nature of free shear jets is well understood and heavily covered in the fluid mechanics literature. On the other
At the Iggesund mill there are several methods and equipments in laboratory scale that simulate the offset printing process in order to evaluate mottle tendency or ink tack for instance. However, it is not possible to study the effect of pre-damping prior
We studied the assembly behavior of a polybutadiene-b-poly(ethylene oxide) diblock copolymer in methanol, cyclohexane, and the corresponding partially miscible binary solvent system. Dynamic light scattering indicates that the copolymer forms coexisting spherical and cylindrical micelles in both of the pure solvents. In
Templating ordered assemblies of magnetic oxide nanoparticles within self-assembled diblock copolymers of varying morphologies is an important problem with a wide applicability such as in electromagnetics, optical devices, metal catalysts, medicine and biology. In this thesis, the effects of different polymer structures
