  • When students start an undergraduate course in engineering, they experience a step change in the level of complexity of the materials that had to be learned. Fluid Mechanics is one such module taught in the first year of the engineering undergraduate courses. It is a core module for Chemical, Mechanical and Civil engineers. The concepts may seem difficult and hard to grasp at the first instance but as the knowledge broadens, one may find it fascinating. This book is a collection of lecture notes developed from a series of lectures delivered to first year Chemical Engineers.

  • The contribution to GDP growth can be hardly differentiated between countries and sectors, therefore we simply summarize our average estimates to the European countries. As shown in Table 1, the range is between 0.05% in the short run under slow adoption and 0.3% in the medium run under fast adoption of cloud comput- ing.

  • Seats for gate valves are either provided integral with the valve body or in a seat ring type of construction. Seat ring construction provides seats which are either threaded into position or are pressed into position and seal welded to the valve body. The latter form of construction is recommended for higher temperature service. Integral seats provide a seat of the same material of construction as the valve body while the pressed-in or threaded-in seats permit variation. Rings with hard facings may be supplied for the application where they are required.

  • The culm of the bamboo is covered by its hard epidermis and inner wax layer. It also lacks ray cells as radial pathways. Several results have revealed that bamboo is difficult to treat with preservatives [Liese 1998; Lee 2001]. An oil-bath treatment can successfully protect against fungal attack, but severe losses in strength have to be expected [Leithoff and Peek 2001]. Since the amount of each chemical composition of bamboo varies with age, height, and layer, the chemical compositions of bamboo are correlated with its physical and mechanical properties.

  • Fiscal, monetary and regulatory policymakers around the world may be asking the same questions. Why was my country hit so hard by the recent events while others were spared? In this paper we examine whether national authorities in places that suffered severely during the global financial crisis are justified in believing they were innocent victims and that the variation in national outcomes was essentially random.

  • This paper investigates the class of TreeTuple MCTAG with Shared Nodes, TTMCTAG for short, an extension of Tree Adjoining Grammars that has been proposed for natural language processing, in particular for dealing with discontinuities and word order variation in languages such as German. It has been shown that the universal recognition problem for this formalism is NP-hard, but so far it was not known whether the class of languages generated by TT-MCTAG is included in PTIME. We provide a positive answer to this question, using a new characterization of TTMCTAG. ...

  • Although the overall technical efficiency of the system has increased considerably, mainly due to the introduction of output-based payment systems, allocative efficiency remains a problem. Considerable variations exist in service delivery both geographically and by specialization, and equity of access is far from being realized, a fact which is mirrored in differing health outcomes for different population groups.
