X-Rays are used as reliable technique for today’s quality assurance of safety critical parts, for example in the automotive or in the aerospace industry. Radiography systems are used to ensure a high throughput in the field of hundred percent testing of a batch. In such systems digital images are acquired by using either flat-panel detectors with a high dynamic range or image intensifiers inclu...

intramedullary nailing of femoral shaft fractures, first introduced by Hey Groves in 1918 and later popularised by K#{252}ntscher (1940, 1958, 1967), B#{246}hler (1951), Street (1951) and Lottes ( 1953), is in most current textbooks described as a routine surgical operation. It is regarded as the method of choice in transverse and short oblique fractures of the femoral shaft (B#{246}hler 1951 :...

A visionics device creates a pictorial representation of the external scene for the pilot. The ultimate objective of these systems may be to electronically generate a form of Visual Meteorological Conditions (VMC) to eliminate weather or time-of-day as an operational constraint and provide enhancement over actual visual conditions where “eye-limiting” resolution may be a limiting factor. Empiri...

A major goal in ultrashort wavelength laser research is the development of practical laser sources that can impact applications. Of particular interest is the demonstration of compact “table-top” amplifiers capable of generating soft x-ray pulses of substantial energy. Such development motivates the demonstration of gain media generated by compact devices that can be successfully scaled in leng...

University students, in groups of 3 or 4, discussed legal aspects of commercial surrogacy and aftenvards ranked the relative influence of each group member. As predicted, high-influence members spoke more words and had more successful turns during the conversation than low-influence members. The latter used a greater rate of intonation and intensifiers than the former. A closer examination of t...

Haemorrhage following major injury remains the most common potentially preventable cause of traumatic death with exsanguination typically occurring within three hours of injury. Key to improving outcomes is a “care bundle” of measures to facilitate early diagnosis, rapid haemorrhage control, systemic and topical haemostatic support and short scene times [1]. The last decade has seen a paradigm ...

A tunable excimer laser at 248 nm (KrF) and 193nm (ArF) has been used to monitor two-dimensional OH and NO distributions in the turbulent flame of a 100 kW natural gas burner. Spatially resolved fluorescence (spatial resolution better than 1.0 mm) from a 20 cm x 20 cm area is collected under single shot conditions. We describe the problems encountered when laser-induced fluorescence imaging tec...

Radiography is one of the oldest and the most widely used NDT method for the detection of volumetric defects in welds and castings. Once a radiograph of a weld or a casting or an assembly is taken, the radiographer examines the same. The task of the radiographer consists of identifying the defects and quantitatively evaluating the same based on codes and specifications. Radiographic interpretat...
