Thermal barrier coating (TBC) systems are known to be extremely sensitive the applied thermo-mechanical loading in terms of both microstructure evolution and subsequent damage, leading final failure by ceramic top-coat layer spallation. The analysis relationship between mechanical behavior is limited scatter experimental results. Based on a typical TBC system for columnar top-coat, this study f...

A model photosensitizer (D5) for application in dye-sensitized solar cells has been studied by a combination of XRD, theoretical calculations, and spectroscopic/chemometric methods. The conformational stability and flexibility of D5 and molecular interactions between adjacent molecules were characterized to obtain the driving forces that govern D5 uptake and grafting and to infer the most likel...

Data base management evolved during the sixties and seventies. The evolution period was protracted. Many driving forces impacted the evolution and it is the aim of this paper to analyze these driving forces (some technical and some political) and to discuss the impact of each. The driving forces are identified as follows: higher level languages, generalization of software, non-procedural approa...

This section describes a simplified version of the dynamic IS − LM model in Blanchard (1981), that extends this elementary macroeconomic scheme along two dimensions: (i) by considering dynamics, and (ii) by enlarging the set of financial markets beyond the traditional "money" and "bonds". In the model below, the latter extension is limited to the stock market. Stock prices have a forward-lookin...

Many advanced technologies center on devices of small feature sizes made of diverse materials. Internal stresses that arise in the devices during fabrication and use can result in fracture. Fracture of an individual feature in such a device may impair the function of the device.The materials surrounding the feature have a constraining effect on the elastic energy available to drive the fracture...

a b s t r a c t “addiction” is a multifaceted complicated disorder with many interrelated causes, as well as environmental and genetic features. several hereditary variables that have an effect on these features might work in together to influence vulnerability and the extent of being an addict. molecular re-sequencing of the latest and formerly researched genes holds a crucial place with regar...
