The accuracy of object reconstruction was tested with two medium format cameras made by ALPA of Switzerland. Both cameras have been equipped with a 33 megapixel Leaf Aptus 75 digital camera back and a 47 mm focal length Schneider Apo-Digitar lens. The first test was carried out with the lens in “normal” position. In the second test, the principal point of another Apo-Digitar lens type was decen...

L-type Ca(2+) channels possess a Ca(2+)-dependent inactivation (CDI) mechanism, affording feedback in diverse neurobiological settings and serving as prototype for unconventional calmodulin (CaM) regulation emerging in many Ca(2+) channels. Crucial to such regulation is the preassociation of Ca(2+)-free CaM (apoCaM) to channels, facilitating rapid triggering of CDI as Ca(2+)/CaM shifts to a cha...

2 Machine tool performance from the point of view of compliance to tolerances, surface definition, etc., is determined essentially by the accuracy of machine movement. For precision machining it is therefore important to measure and, if necessary, compensate for deviations in motion. Standards and directives for inspecting machine tools, such as ISO 230-2, ISO 230-3, ISO 230-4 and VDI/DGQ 3441,...

An 18-month-old boy presented with abdominal pain, vomiting, diarrhea, and poor appetite for 6 days. He had been given a multivitamin preparation once daily, containing 50.000 IU of vitamin D and 10.000 IU of vitamin A for a wide anterior fontanelle for about three months. He presented with hypercalcemia, low levels of parathyroid hormone (PTH), and very high serum 25-hydroxyvitamin D (25-OHD) ...

Abstract New trends and technologies in product creation increase complexity, but at the same time create new potentials such as efficiency rise task processing by Artificial Intelligence. Established models early phase of W-model or Aachener Innovation Management model, do not fully exploit these field strategic planning innovation management (SPPIM). For this reason, existing are analysed SPP...

In this study, Al2O3, TiO2 and Al2O3+ 3wt%TiO2 coatings were deposited on AZ31 Mg alloy substrate by plasma spraying. The structurally characterized scanning electron microscopy X-ray diffraction. Corrosion experiments carried out in 3.5% NaCl solution. Adhesion tests performed according to daimler benz VDI-3198 standard. A coating layer of approximately 70 microns thickness was deposited. High...

Design guidelines have been developed over the past 50 years. Analyzing this development gives interesting insights into the changing character of the design guidelines. Special insights are obtained concerning the intention and direction of the guidelines. These insights give, on the one hand, explanations for the still reserved application and acceptance of design guidelines, and on the other...
