One of these additive manufacturing technologies is “Fused Deposition Modeling” (FDM). From a 3D-CAD data set, components and assemblies are manufactured out of thermoplastic material in only a few working steps. Native software automatically slices the data, calculates the support structures, and creates toolpaths. The parts then are built up layer by layer by means of an additive process. An extrusion head deposits the molten thermoplastic filament to create each layer. This technology began as a process for creating prototype parts; recently it has found new utility in the production of manufacturing tools and as a manufacturing process for end-use parts. In order to be used as a part for serial production, the components must possess the required mechanical properties. To this end, not only is the chosen material relevant, but a correct process control is also necessary. An interesting material for the aircraft and automotive industry is the material PEI with the trade name Ultem*9085. This material should typically be used on FDM-machines for the manufacturing of end products. The aim of the research is to determine the present mechanical data based on the process control, as well as reproducibility from job to job. In this work the influence of the orientation and the structure of the manufactured parts based on the mechanical data are analyzed. Sample parts are generated with the given parameters of the native software based upon the CAD data. First, specimens were analyzed concerning their geometry and configuration. The dimensions and weight were measured. The mechanical tests conducted were the tensile and compression tests.}}, author = {{Bagsik, A. and Schöppner, Volker and Klemp, E.}}, booktitle = {{Proceedings of International Conference Polymeric Materials}}, isbn = {{978-3-868-29282-4}}, title = {{{FDM Part Quality Manufactured with ULTEM 9085}}}, doi = {{https://docplayer.net/255735-Fdm-part-quality-manufactured-with-ultem-9085.html}}, year = {{2010}}, } @inbook{36036, author = {{Schlegel-Matthies, Kirsten}}, booktitle = {{Auf dem Weg zum Jugendintegrationskonzept.

Recently, we identified a loss-of-function mutation in the alpha-subunit of ENaC (alphaF61L) in an atypical CF patient without mutations in CFTR. To investigate the functional effect of this mutation, we expressed human wild-type alpha beta gamma-ENaC or mutant alpha(F61L) beta gamma-ENaC in Xenopus laevis oocytes. The alphaF61L mutation reduced the ENaC mediated whole-cell currents by approximately 90%. In contrast, the mutation decreased channel surface expression only by approximately 40% and did not alter the single-channel conductance. These findings indicate that the major effect of the mutation is a reduction of the average channel open probability (P(o)). This was confirmed by experiments using the betaS520C mutant ENaC which can be converted to a channel with a P(o) of nearly one, and by experiments using chymotrypsin to proteolytically activate the channel. These experiments revealed that the mutation reduced the average P(o) of ENaC by approximately 75%. Na(+) self inhibition of the mutant channel was significantly enhanced, but the observed effect was too small to account for the large reduction in average channel P(o). The ENaC-activator S3969 partially rescued the loss-of-function phenotype of the alphaF61L mutation. We conclude that the alphaF61L mutation may contribute to respiratory symptoms in atypical CF patients.}}, author = {{Huber, Regina and Krueger, Bettina and Diakov, Alexei and Korbmacher, Judit and Haerteis, Silke and Einsiedel, Jürgen and Gmeiner, Peter and Azad, Abul and Cuppens, Harry and Cassiman, Jean-Jaques and Korbmacher, Christoph and Rauh, Robert}}, journal = {{Cellular Physiology and Biochemistry}}, number = {{001}}, pages = {{145–158}}, publisher = {{S.

The central quantity is the transverse spin susceptibility, from which the complete excitation spectrum, including single-particle spin-flip Stoner excitations and collective spin-wave modes, can be obtained. The susceptibility is derived from many-body perturbation theory and includes dynamic correlation through a summation over ladder diagrams that describe the coupling of electrons and holes with opposite spins. In contrast to earlier studies, we do not use a model potential with adjustable parameters for the electron-hole interaction but employ the random-phase approximation. To reduce the numerical cost for the calculation of the four-point scattering matrix we perform a projection onto maximally localized Wannier functions, which allows us to truncate the matrix efficiently by exploiting the short spatial range of electronic correlation in the partially filled d or f orbitals. Our implementation is based on the full-potential linearized augmented-plane-wave method. Starting from a ground-state calculation within the local-spin-density approximation (LSDA), we first analyze the matrix elements of the screened Coulomb potential in the Wannier basis for the 3d transition-metal series. In particular, we discuss the differences between a constrained nonmagnetic and a proper spin-polarized treatment for the ferromagnets Fe, Co, and Ni. The spectrum of single-particle and collective spin excitations in fcc Ni is then studied in detail. The calculated spin-wave dispersion is in good overall agreement with experimental data and contains both an acoustic and an optical branch for intermediate wave vectors along the [100] direction. In addition, we find evidence for a similar double-peak structure in the spectral function along the [111] direction. To investigate the influence of static correlation we finally consider LSDA+U as an alternative starting point and show that, together with an improved description of the Fermi surface, it yields a more accurate quantitative value for the spin-wave stiffness constant, which is overestimated in the LSDA.}}, author = {{Şaşıoğlu, Ersoy and Schindlmayr, Arno and Friedrich, Christoph and Freimuth, Frank and Blügel, Stefan}}, issn = {{1550-235X}}, journal = {{Physical Review B}}, number = {{5}}, publisher = {{American Physical Society}}, title = {{{Wannier-function approach to spin excitations in solids}}}, doi = {{10.1103/PhysRevB.81.054434}}, volume = {{81}}, year = {{2010}}, } @article{26893, author = {{Shi, Lijie and Wudy, Stefan A and Buyken, Anette and Hartmann, Michaela F and Remer, Thomas}}, issn = {{0002-9165}}, journal = {{The American Journal of Clinical Nutrition}}, pages = {{1321--1328}}, title = {{{Body fat and animal protein intakes are associated with adrenal androgen secretion in children}}}, doi = {{10.3945/ajcn.2009.27964}}, year = {{2009}}, } @article{26894, author = {{Karaolis-Danckert, Nadina and Buyken, Anette and Sonntag, Antje and Kroke, Anja}}, issn = {{0002-9165}}, journal = {{The American Journal of Clinical Nutrition}}, pages = {{1559--1565}}, title = {{{Birth and early life influences on the timing of puberty onset: results from the DONALD (DOrtmund Nutritional and Anthropometric Longitudinally Designed) Study}}}, doi = {{10.3945/ajcn.2009.28259}}, year = {{2009}}, } @article{26895, author = {{Cheng, Guo and Gerlach, Steffi and Libuda, Lars and Kranz, Sibylle and Günther, Anke L.

Therefore, we validated a self-completion 24 h recall questionnaire (RQ) focusing on beverage consumption with a 24 h weighed record (WR).DesignThirty-five voluntary participants from the DONALD (Dortmund Nutritional and Anthropometric Longitudinally Designed) Study cohort aged 7–9 years completed the RQ. The illustrated RQ required ticking the number of glasses of seven beverage categories consumed in five time intervals in the previous 24 h. As a reference, parents completed weighed records of their child’s diet. Agreement between the RQ and WR was tested by classification into consumers and non-consumers (kappa coefficients, κ), by the children’s ability to estimate the exact beverage and total volume consumed (Wilcoxon signed-rank test, Spearman rank correlation), and by ranking children according to reported beverage volumes.ResultsThe RQ and WR showed a good level of agreement for classifying participants into consumers and non-consumers of the single beverage categories (κ values between 0·78 and 0·94). Correlation coefficients for the volume of the single categories ranged between 0·81 and 0·91. The total beverage volume was overestimated in the RQ, on average, by 114 ml (P = 0·015). Agreement in ranking into tertiles by beverage volume was moderate to good for juice/soft drinks (κ = 0·44), milk (κ = 0·57) and water (κ = 0·70), but fair for the total beverage volume (κ = 0·23).ConclusionsOur self-completion 24 h RQ could estimate the consumption of several beverage categories among young children at the group level, but quantification of total beverage volume was flawed.}}, author = {{Muckelbauer, Rebecca and Libuda, Lars and Kersting, Mathilde}}, issn = {{1368-9800}}, journal = {{Public Health Nutrition}}, pages = {{187--195}}, title = {{{Relative validity of a self-completion 24 h recall questionnaire to assess beverage consumption among schoolchildren aged 7 to 9 years}}}, doi = {{10.1017/s1368980009990759}}, year = {{2009}}, } @article{27133, author = {{Cheng, G. and Karaolis-Danckert, N. and Libuda, Lars and Bolzenius, K. and Remer, T. and Buyken, Anette E.}}, issn = {{0002-9262}}, journal = {{American Journal of Epidemiology}}, pages = {{667--677}}, title = {{{Relation of Dietary Glycemic Index, Glycemic Load, and Fiber and Whole-Grain Intakes During Puberty to the Concurrent Development of Percent Body Fat and Body Mass Index}}}, doi = {{10.1093/aje/kwn375}}, year = {{2009}}, } @article{27134, author = {{Muckelbauer, R. and Libuda, Lars and Clausen, K. and Kersting, M.}}, issn = {{0305-1862}}, journal = {{Child: Care, Health and Development}}, pages = {{851--857}}, title = {{{Long-term process evaluation of a school-based programme for overweight prevention}}}, doi = {{10.1111/j.1365-2214.2009.00993.x}}, year = {{2009}}, } @article{27135, author = {{Muckelbauer, Rebecca and Libuda, Lars and Clausen, Kerstin and Reinehr, Thomas and Kersting, Mathilde}}, issn = {{1662-4033}}, journal = {{Obesity Facts}}, pages = {{282--285}}, title = {{{A Simple Dietary Intervention in the School Setting Decreased Incidence of Overweight in Children}}}, doi = {{10.1159/000229783}}, year = {{2009}}, } @article{27136, author = {{Muckelbauer, R. and Libuda, Lars and Clausen, K. and Toschke, A.
