The minimally-invasive or endoscopic mitral valve surgery is one of the most attractive and most interesting areas of the modern heart surgery. The book describes first all practical steps necessary in a clinic from the idea of the introduction of the minimally-invasive mitral valve surgery up to practical realization of the operation program. The initial explanation of organizational and financial aspects allows an exact resource planning and protects against wrong expectations and failures. An extensive and detailed representation of the reconstruction technologies possible today as well as the specific features of her endoscopic application allow quick learning of the surgical technology. Numerous tips and tricks and informative pictures of the most frequent findings and the accompanying reconstruction technologies underline the practical orientation of the book.

The book focuses on design and computational issues related to fixtures and armatures in hydronic heating installations, especially regulation valves, their selection, operating principles, types and construction. The analysis is complemented by connection diagrams, drawings, photos of the valves and computational examples of their selection and operation parameters when used in a pipework and a controlled object, like a radiator. It also discusses issues related to the so-called valve authority, one of the main parameters determining the quality of the valve regulation process. Further, it includes an extensive theoretical framework along with a detailed mathematical analysis and proposes new algorithms, which have been verified and confirmed experimentally. Based on this analysis, the book presents the author´s analytical approach for sizing a regulation valve, as well as an innovative design solution for a regulation valve without the limitations of the valves currently available on the market. Lastly, it introduces a new verified method of calculating the valve pre-setting. Intended for engineers dealing with heating issues, scientists and students studying environmental engineering, energetics and related fields, the book is also useful for lecturers, designers, and those operating heating installations, as well as authors of computer programs for thermal and hydraulic balancing of heating installations.

About Railroad Raiders: The focus of this selection concerns both the Federal and Confederate efforts to disable or maintain the railroads within the active theaters of the war. Real railroads of iron and steam and ribbons of steel vanishing into the horizon quickly became a strategic objective of both armies in the Civil War. Raiders and protectors were deployed both North and South. The damage inflicted on roadways and rolling stock was not always easy to accomplish. The simplest method of slowing a train was to remove a small section of rail, but once spotted the gap was not difficult to repair. Both sides learned to tear up long sections of track, pile up and set fire to the ties, and heat and bend the iron. This was temporarily effective, but the rails could often be reheated, straightened out, and spiked back into place. The destruction of bridges, trestles, rolling stock, and especially engines was more difficult and expensive to undo. It was found that to permanently disable a locomotive, however, smashing cylinder heads, pumps, links, and valve stems was not enough. The parts had to be scattered, taken away, or buried or thrown into an inaccessible body of water. It is the author´s purpose to record this often under-reported aspect of the Civil War for both military and railroading enthusiasts. Most Civil War historians concentrate on the strategic and military aspects of the railroading industry, and they rather uncritically mention engineering and other technical factors as if they were simply founded or well established. They were not. In many cases, the same sources and traditions are always quoted with no investigation into their accuracy, and no further understanding of the matter at hand is attempted. The Confederate Railroads, for instance, have only been given a detailed examination once. The Railroads of the Confederacy, by Robert Black (1952), was written 60 years ago. 1. Language: English.
