Abstract: A method for operating an internal combustion engine involves using an injection valve to post-inject fuel into at least one cylinder of the internal combustion engine in order to help regenerate a particulate filter that is arranged in an exhaust system of the internal combustion engine, downstream of an oxidation catalyst. A closing moment of a discharge valve of a cylinder of the internal combustion engine is advanced when the temperature of the oxidation catalyst is in a first temperature range, and the post-injections are performed when the temperature of the oxidation catalyst is in a second temperature range, an upper limit of the first temperature range having a lower value that an upper limit of the second temperature range.

Abstract: A barrier onto the surface of a subterranean formation may be formed by pumping into a wellbore within a well hydrophobically modified polysaccharides. A pressure differential is created between the reservoir pressure and formation pressure within the well. The micellular hydrophobically modified polysaccharides self-align onto the face of the formation to form the barrier. Flow of fluids into the subterranean formation is thereby prohibited.

Abstract: A dynamo-electric machine includes a self-supporting housing that has a laminated core section and at least one connecting section in the axial extension of the laminated core section. The laminated core section accommodates and secures, and at least sectionally surrounds all sides of, a laminated core of a stator. The individual sheets of the laminated core have a basic outer shape with an especially octagonal cross-section, a stator bore surrounded by radially arranged grooves which are evenly distributed along the circumference of the stator bore, a yoke back that radially adjoins the grooves and extends equidistantly from the stator bore, and axial cavities in the sheet, in regions between the yoke, back and the basic outer shape of the sheets.

Abstract: A laundry treatment device includes a treatment chamber for receiving items to be washed and a steam generator supplied with water from a water source by a pump. A first line connects the steam generator to the treatment chamber, and an inlet is provided for introducing steam into the treatment chamber. Arranged between the steam generator and the treatment chamber is a nebulizer facility arranged which is connected by way of a switching valve via second lines to the treatment chamber.
