It has become increasingly recognized that IT organizations must ensure that IT services are aligned to business needs and actively support them. Therefore, the internal IT service management processes are under constant improvement.

Crystalline Cs2KMnF6, when prepared below 500°C, adopts a tetragonal elpasolite structure type. Differential scanning calorimetric investigations indicated that Cs2KMnF6 undergoes a phase transition from the low-temperature tetragonal phase (LT) to a high-temperature phase (HT) at about 530°C. Single crystals of the new HT phase could be obtained by annealing a crystalline LT specimen at 600°C fol

Even under a pressure of 46 GPa, the low-symmetry lone-pair structures of isoelectronic TIF and PbO (see picture for β-PbO), classic examples of systems with a stereochemically active lone pair, resist transformation into the corresponding high-symmetry NaCl and CsCl structures. Ab initio calculations allowed a simple bonding picture for lone-pair structures involving inert-pair elements to be dev

The compressibility and thermal expansion of the cubic silicon nitride (c-Si3N4) phase have been investigated by performing in situ x-ray powder-diffraction measurements using synchrotron radiation, complemented with computer simulations by means of first-principles calculations. The bulk compressibility of the c-Si3N4 phase originates from the average of both Si-N tetrahedral and octahedral compr

Societal and technological transformation in the face of climate change will be won or lost in our cities and urban communities. This is not just because of the global urban demographic shift with more than 50 percent of the population now living in urban conditions, or because cities contribute around 70 to 80 percent of greenhouse gas emissions, but it is as much to do with the growing economic

The steps involved in the grafting of mesencephalic and septal embryonic tissue in the form of dissociated cell suspensions are described in detail. This includes dissection of the donor embryos, incubation in trypsin, mechanical dissociation, and stereotaxic injection into the brains of adult recipient rats. Some of the technical problems and limitations are discussed.

The proper management of the signal to noise ratio margin is important for improving the stability of digital subscriber line (DSL) networks and increasing the customer satisfaction regarding services such as triple-play. This work presents a novel algorithm for multiuser margin optimization that benefits from the relationships between power and margin adaptation. The proposed multiuser margin max

Design and stress analysis of regular double-tapered beams and double-tapered beams with a flattened apex region is considered, focusing on perpendicular to grain tensile stress in apex region. Double-tapered beams with flattened apex region are analyzed since the geometry is such that the perpendicular to grain tensile stress may be reduced compared to a regular double-tapered beam of correspondi
