    We present the magnetic temperature phase diagrams of the CrB- and FeB-type orthorhombic phases of the DySi compound, determined from high-quality powder XRPD and neutron diffraction, as well as the sample microstructure as determined by HRTEM. Both phase diagrams comprise a HT (T c1 , T c2 -T N ) and a LT range (5 K-T c1 , T c2 ) separated by a monoclinic phase transition at T c1 =T c2 =23.5 K well below the second-order Neel transition (T N =40 K). The transition paths are for CrB-type Cmcm (HT) T c1 →C2/m11 (LT), and for FeB Pnma (HT) T c2 →P2 1 /n11 (LT). The transitions are related to non-monotonous changes of the lattice and structural parameters displaying anomalies at T c1 , T c2 and slight volume changes. For the CrB-type the monoclinic angle decreases smoothly from T c1 down to 5 K and the maximum strain experienced by the crystal lattice in the (0 2 1) direction was found at T c1 . In the FeB-type, in addition to the magneto-elastic transition at T c2 =23.5 K, minor anomalies are found at 13.5 K in the temperature dependence of the monoclinic angle and the maximum strain along (0 1 1). Both temperatures mark the sequence of changes in the magnetic domain microstructure observed in FeB: below T 2 =23.5 K the incommensurate HT magnetic phase with q 3 ∼(01/2 1/7 ) disproportionates into two LT phases q 3 ∼(01/2 1/(11) )T 2 and q 2 ∼(01/2 1/6 ) coexisting in the form of domains with portions varying with T going from T 2 down to 13.5 K (q 2 increasing at the cost of q 3 ). This behaviour could be related to structural inhomogeneities below the first-order magneto-elastic transition T c2 , if one assumes a broad two phase range, where the HT (Pnma) phase coexists with (P2 1 /n) as a metastable phase at LT in the form of domains with different magnetic behaviour. - Research highlights: → Unusual magneto structural transition in dimorphic DySi (FeB- and CrB-type, T N =40 K) at T 2 =23.5 K. → Electron microscopy shows no intergrowth domains of the

  3. Structure of the VipA/B Type VI Secretion Complex Suggests a Contraction-State-Specific Recycling Mechanism

    Full Text Available The bacterial type VI secretion system is a multicomponent molecular machine directed against eukaryotic host cells and competing bacteria. An intracellular contractile tubular structure that bears functional homology with bacteriophage tails is pivotal for ejection of pathogenic effectors. Here, we present the 6 Å cryoelectron microscopy structure of the contracted Vibrio cholerae tubule consisting of the proteins VipA and VipB. We localized VipA and VipB in the protomer and identified structural homology between the C-terminal segment of VipB and the tail-sheath protein of T4 phages. We propose that homologous segments in VipB and T4 phages mediate tubule contraction. We show that in type VI secretion, contraction leads to exposure of the ClpV recognition motif, which is embedded in the type VI-specific four-helix-bundle N-domain of VipB. Disaggregation of the tubules by the AAA+ protein ClpV and recycling of the VipA/B subunits are thereby limited to the contracted state.

    Recycled NdFeB magnets are emerging as a viable alternative to virgin NdFeB, because of lower production costs and environmental impacts. Recycled NdFeB magnets produced via the recently reported magnet-to-magnet (m2 m™) recycling process display unanticipated enhancements of magnetic and physical properties that may arise because of their unique microstructure. In the present study, we compare electrical transport and magnetic properties of these recycled magnets (Grade: N42SH, Br = 1289 mT, Hcj = 1876 kA/m, BHmax = 323.4 kJ/m3, Dy content = 4.0 wt%) with an equivalent grade of commercial NdFeB magnet produced from virgin material by conventional techniques (Grade: N42SH, Br = 1215 mT, Hcj = 1943 kA/m, BHmax = 285.0 kJ/m3, with Dy content = 4.6 wt%). Atomic force microscopy (AFM) and magnetic force microscopy (MFM) analyses revealed very similar surface morphology and magnetic structure for the virgin and recycled samples. However, bulk electrical transport measurements demonstrated a 27% enhancement in the resistivity of the recycled magnets. This suggests that the electrical properties of NdFeB alloys are enhanced during Grain Boundary Engineering™ (GBE™). Moreover, point-contact measurements, used to probe the electrical transport properties on the microscopic scale, found similar results to those of the bulk measurements.

    The B-type lanthanoid(III) chloride oxoselenates(IV) MCl[SeO 3 ] (M = Sm - Lu) crystallize in the orthorhombic space group Pnma (no. 62) with Z = 4 in the structure type of HoCl[TeO 3 ]. Their lattice constants are decreasing following the lanthanoid contraction from a = 730.01(7), b = 707.90(7), c 895.64(9) pm for SmCl[SeO 3 ] to a = 714.63(7), b = 681.76(7), c = 864.05(9) pm for LuCl[SeO 3 ]. In contrast to NdCl[SeO 3 ], the only representative of the A-type structure, where the coordination numbers of the Nd 3+ cations are 7+2 and 8, the B-type structure is dominated by pentagonal bipyramids [MO 5 Cl 2 ] 9- (CN(M 3+ ) = 7), which are connected via trans-oriented O..O edges to ∞ 1 {[MO 4/2 e O 1/1 t Cl 2/1 t ] 5- } chains (e = edge-sharing, t = terminal) running parallel to the [010] direction. Their inclination relative to each other allows for an alternating interconnection of these chains via Cl - and ψ 1 -tetrahedral [SeO 3 ] 2- anions to form a three-dimensional structure. The distances within the [SeO 3 ] 2- groups are in the normal range (d(Se-O) = 165 - 172 pm), while those of the O 2- and Cl - anions to the central M 3+ cation diminish in dependence of the increasing atomic number (d(M-O) = 226 - 244 pm / 216 - 232 pm, d(M-Cl) 277 - 278 pm / 266 - 270 pm, M = Sm / Lu). For the synthesis of the chloride oxoselenates(IV) MCl[SeO 3 ] the respective lanthanoid sesquioxide (M 2 O 3 ) and selenium dioxide (SeO 2 ) were reacted with either an eutectic mixture of RbCl and LiCl or with the corresponding lanthanoid trichloride (MCl 3 ) in evacuated silica ampoules for either five weeks at 500 C or one week at 850 C.

    Full Text Available Copper is a crucial ion in cells, but needs to be closely controlled due to its toxic potential and ability to catalyse the formation of radicals. In chloroplasts, an important step for the proper functioning of the photosynthetic electron transfer chain is the delivery of copper to plastocyanin in the thylakoid lumen. The main route for copper transport to the thylakoid lumen is driven by two PIB-type ATPases, Heavy Metal ATPase 6 (HMA6 and HMA8, located in the inner membrane of the chloroplast envelope and in the thylakoid membrane, respectively. Here, the crystal structures of the nucleotide binding domain of HMA6 and HMA8 from Arabidopsis thaliana are reported at 1.5Å and 1.75Å resolution, respectively, providing the first structural information on plants Cu+-ATPases. The structures reveal a compact domain, with two short helices on both sides of a twisted beta-sheet. A double mutant, aiding in the crystallization, provides a new crystal contact, but also avoids an internal clash highlighting the benefits of construct modifications. Finally, the histidine in the HP motif of the isolated domains, unable to bind ATP, shows a side chain conformation distinct from nucleotide bound structures.

    It was prepared the alloy FeNiB for chemical reduction, using four p H values (5, 6, 7 and 7.5). To p H=6 partially oxidized particles were obtained, between 16 and 20%. In the synthesis to other p H values, the obtained particles were highly oxidized (65-90%) according to the X-ray diffraction results, in all the preparations the particles were partially crystallized, with crystal size that varied between 4 and 10 nm. The structure of these particles can be consider that they are formed by a nucleus due to the alloy and an oxide armor recovering it. (Author)

    The Neuberger review made a number of recommendations to improve end of life care, including research into the biology of dying. An important aspect of the biology of dying is the identification of biomarkers as indices of disease processes. Biomarkers have the potential to inform the current, limited understanding of the dying process and assist clinicians in recognising dying, in particular how to distinguish dying from reversible acute deterioration. To critically appraise the literature on biological factors that may be used as prognostic indicators in advanced cancer patients and to identify candidate biomarkers of the dying process that can be measured serially in cancer patients' bodily fluids. A systematically structured review was conducted using three electronic databases. A hand search of six peer-reviewed journals and conference abstracts was also conducted. Studies reporting prognostic biomarkers in cancer patients with a median survival of ≤90 days and post-mortem studies were included. Final levels of evidence and recommendations were made using the Evidence Based Medicine modified GRADE system. 30 articles were included. Seven prognostic biological factors demonstrated Grade A evidence (lymphocyte count, white blood cell count, serum C-reactive protein, albumin, sodium, urea and alkaline phosphatase). An additional eleven prognostic factors were identified with Grade B evidence (platelet count, international normalised ratio, serum vitamin B12, prealbumin, bilirubin, cholesterol, aspartate aminotransferase, alanine transaminase, lactate dehydrogenase, pseudocholinesterase and urate). A number of biomarkers were specifically identified in the last two weeks of life but limitations exist. No post-mortem studies met the inclusion criteria. The biology of dying is an important area for future research, with the evidence focused on signs, symptoms and prognostic factors. This review identifies a number of common themes shared amongst advanced cancer

  10. A process chain for integrating piezoelectric transducers into aluminum die castings to generate smart lightweight structures

    Directory of Open Access Journals (Sweden)

    Stefan Stein

    Full Text Available The application of piezoelectric transducers to structural body parts of machines or vehicles enables the combination of passive mechanical components with sensor and actuator functions in one single structure. According to Herold et al. [1] and Staeves [2] this approach indicates significant potential regarding smart lightweight construction. To obtain the highest yield, the piezoelectric transducers need to be integrated into the flux of forces (load path of load bearing structures. Application in a downstream process reduces yield and process efficiency during manufacturing and operation, due to the necessity of a subsequent process step of sensor/actuator application. The die casting process offers the possibility for integration of piezoelectric transducers into metal structures. Aluminum castings are particularly favorable due to their high quality and feasibility for high unit production at low cost (Brunhuber [3], Nogowizin [4]. Such molded aluminum parts with integrated piezoelectric transducers enable functions like active vibration damping, structural health monitoring or energy harvesting resulting in significant possibilities of weight reduction, which is an increasingly important driving force of automotive and aerospace industry (Klein [5], Siebenpfeiffer [6] due to increasingly stringent environmental protection laws. In the scope of those developments, this paper focuses on the entire process chain enabling the generation of lightweight metal structures with sensor and actuator function, starting from the manufacturing of piezoelectric modules over electrical and mechanical bonding to the integration of such modules into aluminum (Al matrices by die casting. To achieve this challenging goal, piezoceramic sensors/actuator modules, so-called LTCC/PZT modules (LPM were developed, since ceramic based piezoelectric modules are more likely to withstand the thermal stress of about 700 °C introduced by the casting process (Flössel et

    Full Text Available The quality of statistical data covering the economic and social development of the People’s Republic of China has been questioned by international and national data users for years. The reasons for this doubt lie mainly in the structure of the Chinese system of statistics. Two parallel systems exist which operate largely autonomously: the national system of statistics and the sectoral system of statistics. In the area of the national statistical system, the National Bureau of Statistics (NBS has the authority to order and collect statistics. This competence lies with the ministries and authorities below the ministerial level. This article describes and analyses these structures, the resulting problems, and the reform measures taken to date. It also aims to provide a better understanding of the statistical data about the People’s Republic of China and to enable an assessment of them within a changing structural context. In conclusion, approaches to further reforms will be provided based on the author’s long-standing experience in cooperation projects with the official Chinese statistics agencies. Die Qualität der Statistiken zur ökonomischen und sozialen Entwicklung in der Volksrepublik China ist in letzter Zeit sowohl von ausländischen wie auch von einheimischen Nutzern der Daten in Frage gestellt worden. Die Gründe dafür liegen vor allem in der Struktur des Erhebungssystems in China.

    For the electricity production of the EU there are differentiated structures which are based on different natural conditions, political decisions and investments of past decades. It has long been struggled committed to the ''one and correct'' energy policy. But precisely because of the differences in the individual countries, a unified energy and climate policy for the EU is not the right way. Diversity is a strength, which quite the EU Commission considered. Increased understanding of the specifics in other countries should just apply the German politics and the public that all too often judges from their own perspective. [German] Bei der Stromerzeugung in der EU bestehen differenzierte Strukturen, die auf unterschiedlichen natuerlichen Gegebenheiten, politischen Entscheidungen und Investitionen vergangener Jahrzehnte beruhen. Seit langem wird engagiert um die ''eine und richtige'' Energiepolitik gerungen. Doch gerade wegen der Unterschiede in den einzelnen Laendern kann eine vereinheitlichte Energie- und Klimapolitik fuer die EU nicht der richtige Weg sein. Vielfalt ist eine Staerke, was die EU-Kommission durchaus beruecksichtigt. Mehr Verstaendnis fuer die Spezifika in anderen Laendern sollte daher gerade die deutsche Politik und Oeffentlichkeit aufbringen, die allzu oft aus eigener Perspektive heraus urteilt.

  2. Interlocking multi-material components made of structured steel sheets and high-pressure die cast aluminium

    2017-10-01

    Lightweight design is a major driving force of innovation, especially in the automotive industry. Using hybrid components made of two or more different materials is one approach to reduce the vehicles weight and decrease fuel consumption. As a possible way to increase the stiffness of multi-material components, this paper presents a process chain to produce such components made of steel sheets and high-pressure die cast aluminium. Prior to the casting sequence the steel sheets are structured in a modified rolling process which enables continuous interlocking with the aluminium. Two structures manufactured by this rolling process are tested. The first one is a channel like structure and the second one is a channel like structure with undercuts. These undercuts enable the formation of small anchors when the molten aluminium fills them. The correlation between thickness reduction during rolling and the shape of the resulting structure was evaluated for both structures. It can be stated that channels with a depth of up to 0.5 mm and a width of 1 mm could be created. Undercuts with different size depending on the thickness reduction could be realised. Subsequent aluminium high-pressure die casting experiments were performed to determine if the surface structure can be filled gap-free with molten aluminium during the casting sequence and if a gap-free connection can be achieved after contraction of the aluminium. The casting experiments showed that both structures could be filled during the high-pressure die casting. The channel like structure results in a gap between steel and aluminium after contraction of the cast metal whereas the structure with undercuts leads to a good interlocking resulting in a gap-free connection.

    It is essential for the numerical design of con rods to consider the interaction between structural deformation and hydrodynamics in the sliding bearings. Furthermore, the boundary conditions for the sub-system under consideration have considerable influence on the quality of the results. AVL List GmbH, as the developer of the software AVL EXCITE for the calculation of the non-linear dynamic behaviour of engines and power units, has extended the elasto-hydrodynamic bearing module by adding a mixed friction model. This leads to improved results, especially in the area of the small end bearing, and to a more realistic integration of the con rod into the simulation model of the entire system. (orig.)

    Peridotite formed by contact metamorphism and dehydration breakdown of an antigorite schist from the Happo area, central Japan shows a strong olivine crystallographic preferred orientation (Ol CPO). The lack of mesoscale deformation structures associated with the intrusion and the lack of microstructural evidence for plastic deformation of neoblastic grains suggest that olivine CPO in this area did not form as a result of solid-state deformation. Instead, the good correspondence between the original antigorite orientation and the orientation of the newly formed olivine implies the CPO formed by topotactic growth of the olivine after antigorite. Ol CPO is likely to develop by a similar process in subduction zone environments where foliated serpentinite is dragged down to depths where antigorite is no longer stable. The Happo Ol CPO has a strong a-axis concentration perpendicular to the lineation and within the foliation-commonly referred to as B-type Ol CPO. Seismic fast directions parallel to the ocean trench are observed in many convergent margins and are consistent with the presence of B-type Ol CPO in the mantle wedge of these regions. Experimental work has shown that B-type CPO can form by dislocation creep under hydrous conditions at relatively high stresses. There are, however, several discrepancies between the characteristics of natural and laboratory samples with B-type Ol CPO. (1) The formation conditions (stress and temperature) of some natural examples with B-type CPO fall outside those predicted by experiments. (2) In deformation experiments, slip in the crystallographic c-axis direction is important but has not been observed in natural examples of B-type CPO. (3) Experimental work suggests the presence of H2O and either high shear stress or relatively low temperatures are essential for the formation of B-type CPO. These conditions are most likely to be achieved close to subduction boundaries, but these regions are also associated with serpentinization

  14. Structural materialization of stainless steel molds and dies by the low temperature high density plasma nitriding

    Full Text Available Various kinds of stainless steels have been widely utilized as a mold substrate material for injection molding and as a die for mold-stamping and direct stamping processes. Since they suffered from high temperature transients and thermal cycles in practice, they must be surface-treated by dry and wet coatings, or, by plasma nitriding. Martensitic stainless steel mold was first wet plated by the nickel phosphate (NiP, which was unstable at the high temperature stamping condition; and, was easy to crystalize or to fracture by itself. This issue of nuisance significantly lowered the productivity in fabrication of optical elements at present. In the present paper, the stainless steel mold was surface-treated by the low-temperature plasma nitriding. The nitrided layer by this surface modification had higher nitrogen solute content than 4 mass%; the maximum solid-solubility of nitrogen is usually 0.1 mass% in the equilibrium phase diagram. Owing to this solid-solution with high nitrogen concentration, the nitrided layer had high hardness of 1400 Hv within its thickness of 40 μm without any formation of nitrides after 14.4 ks plasma nitriding at 693 K. This nitrogen solid-solution treated stainless steel had thermal resistivity even at the mold-stamping conditions up to 900 K.

  16. Ion-beam enhanced etching for the 3D structuration of lithium niobate; Ionenstrahlverstaerktes Aetzen fuer die 3D-Strukturierung von Lithiumniobat

    The present thesis deals with the usage of the ion-beam enhanced etching (IBEE) for the 3D structuration of lithium niobate (LiNbO{sub 3}).Hereby the approach of the enhancement of the wet-chemical etching rate due to the irradiation with energetic ions is pursued. This method is very success promising for the realization of micro- and nanostructures with perpendicular structural walls as well as small roughnesses. The aim of this thesis consisted therein to form the foundations for the realization of three-dimensional micro- and nanostructures (for instance: Layer systems and photonic crystals) in LiNbO{sub 3} with high optical quality and to demonstrate on selected examples. Conditions for the success of the IBEE structuration technique is first of all the understanding of the defect formation under ion irradiation as well as the radiation-induced structure changes in the crystal and the change of the chemical resistance connected with this. For this the defect formation was studied in dependence on th ion mass, the ion energy, and the irradiation temperature. Thermally induced influences and effects on the radiation damage, as they can occur in intermediate steps in the complex processing, must be known and were studied by means of subsequent temperature treatment. The results from the defect studies were subsequently applied for the fabrication of micro- and nanostructures in LiNbO{sub 3}. Shown is the realization of lateral structure with nearly perpendicular structure walls as well as the realization of thin membranes and slits. The subsequent combination of lateral structuration with the fabrication of thin membranes and slits allowed the three-dimensional structuration of LiNbO{sub 3}. This is exemplarily shown for a microresonator and for a 2D photonic crystal with below lying air slit.

  18. New approaches for the reliability-oriented structural optimization considering time-variant aspects; Neue Ansaetze fuer die zuverlaessigkeitsorientierte Strukturoptimierung unter Beachtung zeitvarianter Aspekte

    The optimization of structures with respect to cost, weight or performance is a well-known application of the nonlinear optimization. However reliability-based structural optimization has been subject of only very few studies. The approaches suggested up to now have been unsatisfactory regarding general possibility of application or easy handling by user. The objective of this thesis is the development of general approaches to solve both optimization problems, the minimization of cost with respect to constraint reliabilty and the maximization of reliability under cost constraint. The extented approach of an one-level-method will be introduced in detail for the time-invariant problems. Here, the reliability of the sturcture will be analysed in the framework of the First-Order-Reliability-Method (FORM). The use of time-variant reliability analysis is necessary for a realistic modelling of many practical problems. Therefore several generalizations of the new approaches will be derived for the time-variant reliability-based structural optimization. Some important properties of the optimization problems are proved. In addition some interesting extensions of the one-level-method, for example the cost optimization of structural series systems and the cost optimization in the frame of the Second-Order-Reliabiity-Method (SORM), are presented in the thesis. (orig.) [German] Die Optimierung von Tragwerken im Hinblick auf die Kosten, das Gewicht oder die Gestalt ist eine sehr bekannte Anwendung der nichtlinearen Optimierung.

    Transmission electron microscopy studies have been carried out on partially disproportionated NdFeB-type alloys. A new intermediate magnetic (NIM) phase has been identified. Moreover, the lamella structure which subsequently develops from the tetragonal NIM phase comprises a tetragonal NdFe-containing (IL) phase and α-Fe. The experimental data show strong evidence of a well-defined crystallographic relation between both the NIM and lamella phases and between the IL phase and α-Fe. These observations give insight into how crystallographic texture, and hence anisotropy, can be developed in NdFeB-type powders processed by the hydrogenation, disproportionation, desorption, and recombination route. copyright 2001 American Institute of Physics

    Recent surveys have found that ~10% of OB-type stars host strong (~1kG), mostly dipolar magnetic fields. The prominent idea describing the interaction between the stellar winds and the magnetic field is the magnetically confined wind shock model. In this model, the ionized wind material is forced to move along the closed magnetic field loops and collides at the magnetic equator creating a shock. As the shocked material cools radiatively it will emit X-rays. Therefore, X-ray spectroscopy is a key tool in detecting and characterizing the wind material confined by the magnetic fields of these stars. Some of these magnetic B-type stars are found to have very short rotational periods. The effects of the rapid rotation on the X-ray production within the magnetosphere have yet to be explored in detail. The added centrifugal force is predicted to cause faster wind outflows along the field lines, which could lead to higher shock temperatures and harder X-rays. However, this is not observed in all rapidly rotating magnetic B-type stars. In order to address this question from a theoretical point of view, we use the X-ray Analytical Dynamical Magnetosphere model, developed for slow rotators and implement the physics of rapid rotation. Using X-ray spectroscopy from ESA’s XMM-Newton space telescope, we observed 5 rapidly rotating B-types stars to add to the previous list of observations. Comparing the observed X-ray luminosity and hardness ratio to that predicted by the XADM allows us to determine the role an added centrifugal acceleration plays in the magnetospheres of these stars.

    Recent spectropolarimetric surveys of bright, hot stars have found that ~10% of OB-type stars contain strong (mostly dipolar) surface magnetic fields (~kG). The prominent paradigm describing the interaction between the stellar winds and the surface magnetic field is the magnetically confined wind shock (MCWS) model. In this model, the stellar wind plasma is forced to move along the closed field loops of the magnetic field, colliding at the magnetic equator, and creating a shock. As the shocked material cools radiatively it will emit X-rays. Therefore, X-ray spectroscopy is a key tool in detecting and characterizing the hot wind material confined by the magnetic fields of these stars.

    Full Text Available Die Verschränkung zweier Ungleichheitsstrukturen – der ‚klassischen‘ Sozialstruktur und der Struktur der Geschlechterverhältnisse – ist für die Autorin eine Ursache dafür, dass seit Einführung der Marktwirtschaft ostdeutsche Frauen massiv vom Arbeitsmarkt verdrängt werden. Aufbauend auf Grundannahmen über die Entstehung moderner Ungleichheitsstrukturen vergleicht Schäfgen die Entwicklung von Sozialstruktur und Geschlechterverhältnissen der BRD und der DDR, die sie beide als moderne Gesellschaften versteht – leider nicht gesellschafts- bzw. modernetheoretisch begründet. Dies hat Konsequenzen: Zwar bestätigt das empirische Material das Vorhandensein ‚klassischer‘ wie auch qua Geschlecht erzeugter Ungleichheiten in beiden deutschen Staaten, aber Schäfgens Vergleich liefert leider keine Differenzierung zwischen den Ausprägungen der Moderne in BRD und DDR. Um die ‚doppelte Ungleichheit‘ in die Analyse einbeziehen zu können, entwickelt Schäfgen das ‚Modell der doppelten Vertikalität‘. Im Kern dieses Modells werden die durch ‚Geschlecht‘ produzierten Ungleichheiten in deren vertikaler Dimension verortet. Fraglich ist, ob Schäfgens Modell theoretischen und methodischen Gewinn bringt: Kann die Substantialisierung von Konzepten wie ‚Klasse‘ oder ‚Geschlecht‘ wirklich der prozessualen Erzeugung und Reproduktion sozialer Ungleichheit auf die Spur kommen?Schäfgen views the interlocking of two systems of inequality-that of ‘traditional’ social inequality and that of gender inequality-as one reason why East German women have been driven out of the labour market since the introduction of a free market economy. Starting from core assumptions about the development of modern structures of inequality, Schäfgen compares the development of social structures and gender relations in the FRG and GDR. Schäfgen merely presumes the two German states to be modern states; unfortunately, she does not explain why she

    Some fully dense, sintered NdFeB-type magnets (employed in VCM disc drives) have been subjected to a recycling process using the hydrogen decrepitation (HD) process. After a brief milling treatment, the powder was aligned, pressed and re-sintered and this procedure was repeated four times with a progressive fall in the density and in the magnetic properties. The chemical analysis indicated that this was due to the progressive oxidation of the Nd-rich material and to some Nd loss by evaporation. The procedure was then repeated but with the addition (blending) of a fine powder of neodymium hydride after the first cycle. It was found that the addition of 1 at.% of neodymium at each stage was sufficient to maintain the density and the magnetic properties of the recycled magnets up to and including the 4th cycle. Inductively coupled plasma (ICP) and metallographic analysis indicated that the neodymium hydride additions compensated for the neodymium loss due to evaporation and to oxidation so that the proportion of Nd-rich material remained approximately constant. The additional amount of Nd{sub 2}O{sub 3} in the blended recycled magnets appeared to inhibit grain growth on the 3rd and 4th cycles when compared to that of the unblended magnets. The next challenge is to see if the process can be scaled-up to an industrial scale.

  17. Massive B-type pulsators in low-metallicity environments

    Massive B-type pulsators such as β Cep and slowly pulsating B (SPB) stars pulsate due to layers of increased opacity caused by partial ionization. The increased opacity blocks the energy flux to the surface of the stars which causes the layers to rise and the opacity to drop. This cyclical behavior makes the star act as a heat engine and the star will thus pulsate. For β Cep and SPB stars the increased opacity is believed to be caused by partial ionization of iron and these stars should therefore contain non-insignificant quantities of the metal. A good test of this theory is to search for β Cep and SPB stars in low-metallicity environments. If no stars are found the theory is supported, but, on the other hand, if a substantial number of β Cep and SPB stars are found in these environments then the theory is not supported and a %solutions solution is needed. With a growing number of identified β Cep and SPB stars in the low-metallicity Magellanic Clouds we seem to be left with the second case. We will in this context discuss recent findings of β Cep and SPB stars in the Magellanic Clouds and some possible solutions to the discrepancy between these observations and the theory. We also describe an ambitious project that we have initiated on the Small Magellanic Cloud open cluster NGC 371 which will help to evaluate these solutions.

    Full Text Available The development of the Managerial Motivation Questionnaire (MMQ: Several criticisms of the psychometric suitability of existing measures of managerial motivation are reported in the literature. This study aimed at developing a new psychometrically sound instrument, the Managerial Motivation Questionnaire (MMQ. This was done on the basis of a comprehensive study of the literature on managerial motivation and the role-motivation theory. The preliminary MMQ was systematically shortened and refined until the final MMQ of 98 items was composed. This was based on social desirability and semantic appraisal, item analysis and factor analysis of the questionnaire. The results indicate that it was possible to develop a final MMQ that was relatively free of social desirability. It further demonstrated satsifactory internal consistencies on two samples (a = 0/90, N = 360; a = 0/91, N = 535, where all subscale items were found to be relatively pure measures of the isolated factors. Although some evidence was found providing support for the reliability of the MMQ, a need for further research on the construct validity of managerial motivation still exists. Opsomming In die literatuur word verskeie punte van kritiek teen die psigometriese geskiktheid van bestaande meetinstrumente van bestuursmotivering gerapporteer. Die doelstelling van hierdie studie was dus om aan die hand van die konseptuele omiyning van bestuursmotivering, en die rolmotiveringsteorie as algemene verwysingsraamwerk, 'n nuwe psigometries aanvaarbare meetinstrument, die Bestuursmotiveringsvraelys (BMV, te ontwikkel. Op grond van sosiale wenslikheids- en semantiese beoordeling, itemontleding en faktorontleding van die voorlopige BMV is die vraelys stelselmatig verkort en verfyn totdat die finale BMV van 98 items saamgestel is. Die resultate dui daarop dat hierdie studie wel daarin geslaag het om 'n finale BMV te ontwikkel wat relatief vry van sosiale wenslikheid is, bevredigende interne

    Full Text Available The 16PF Personality Test as an aid to the assessment centre Assessment centres still remains costly and thime consuming. This study investigates the reduction of time and costs by the use of the 16 PF Personality Test as a method for measuring management dimensions. Promising results were obtained with a relatively small sample for the prediction of initiative and perseverance. Significant multiple correlations were also found for three criteria of management success. Further research may establish the use of the 16 PF as an aid to management assessment and thereby reduce the costs and time involved in assessment centres. Opsomming Takseersentrums se grootste probleem is gelee in die koste en tyd wat dit behels. Hierdie studie ondersoek die moontlikheid om beide te verminder deur die aanwending van die 16 PF Persoonlikheidsvraelys vir die meting van bestuursdimensies. Belowende resultate is met 'n relatiewe klein steekproef bevind ten opsigte van die voorspelling van inisiatiefen deursettingsvermoe. Beduidende meervoudige korrelasies is ook ten opsigte van drie kriteria van bestuursukses bevind. Verdere navorsing kan die gebruik van die 16 PF as hulpmiddel by bestuursevaluering vestig en sodoende die tydsduur en koste van takseersentrums verminder.

    This study sought to identify how urban gay communities are undergoing structural change, reasons for that change, and implications for HIV prevention planning. Key informants (N=29) at the AIDS Impact Conference from 17 cities in 14 countries completed surveys and participated in a facilitated structured dialog about if gay communities are changing, and if so, how they are changing. In all cities, the virtual gay community was identified as currently larger than the offline physical community. Most cities identified that while the gay population in their cities appeared stable or growing, the gay community appeared in decline. Measures included greater integration of heterosexuals into historically gay-identified neighborhoods and movement of gay persons into suburbs, decreased number of gay bars/clubs, less attendance at gay events, less volunteerism in gay or HIV/AIDS organizations, and the overall declining visibility of gay communities. Participants attributed structural change to multiple factors including gay neighborhood gentrification, achievement of civil rights, less discrimination, a vibrant virtual community, and changes in drug use. Consistent with social assimilation, gay infrastructure, visibility, and community identification appears to be decreasing across cities. HIV prevention planning, interventions, treatment services, and policies need to be re-conceptualized for MSM in the future. Four recommendations for future HIV prevention and research are detailed.

    A heater for heating packaged die for burn-in and heat testing is described. The heater may be a ceramic-type heater with a metal filament. The heater may be incorporated into the integrated circuit package as an additional ceramic layer of the package, or may be an external heater placed in contact with the package to heat the die. Many different types of integrated circuit packages may be accommodated. The method provides increased energy efficiency for heating the die while reducing temperature stresses on testing equipment. The method allows the use of multiple heaters to heat die to different temperatures. Faulty die may be heated to weaken die attach material to facilitate removal of the die. The heater filament or a separate temperature thermistor located in the package may be used to accurately measure die temperature.

    Recently, Nagaya et al. (2014) have reported the B-type crystallographic preferred orientation (CPO) of olivine in thermally metamorphosed serpentinites from the Happo ultramafic complex, central Japan, and interpreted the CPO as a result of topotactic growth of olivine after antigorite. Their conclusions require the reconsideration of the genesis of B-type olivine CPO, which is generally believed to be formed by plastic deformation of hydrous peridotites, and could have an impact on structural models of supra-subduction zones. I appreciate the detailed observations by Nagaya et al. (2014) but have to point out that they committed significant misinterpretation of facts and failed to show robust evidence and rationale for their argument.

    2017-12-01

    Full Text Available The bacterioferritin from E. coli (BFR, a maxi-ferritin made of 24 subunits, has been utilized as a model to study the fundamentals of protein folding and self-assembly. Through structural and computational analyses, two amino acid residues at the B-site interface of BFR were chosen to investigate the role they play in the self-assembly of nano-cage formation, and the possibility of building aromatic interaction networks at B-type protein–protein interfaces. Three mutants were designed, expressed, purified, and characterized using transmission electron microscopy, size exclusion chromatography, native gel electrophoresis, and temperature-dependent circular dichroism spectroscopy. All of the mutants fold into α-helical structures and possess lowered thermostability. The double mutant D132W/N34W was 12 °C less stable than the wild type, and was also the only mutant for which cage-like nanostructures could not be detected in the dried, surface-immobilized conditions of transmission electron microscopy. Two mutants—N34W and D132W/N34W—only formed dimers in solution, while mutant D132W favored the 24-mer even more robustly than the wild type, suggesting that we were successful in designing proteins with enhanced assembly properties. This investigation into the structure of this important class of proteins could help to understand the self-assembly of proteins in general.

In die eerste metode word die bepaling deur middel van oplossingsviskometrie gedoen, maar die toksisiteit van die oplosmiddel, asook die tydperk wat dit neem om die bepaling te doen, is ’n probleem. Die tweede metode word beperk deur die kompleksiteit en beskikbaarheid van die apparatuur in Suid-Afrika.

    Hofmann, Andreas

    2012-02-14

    This thesis constitutes a comprehensive study of the surface physics of epitaxial CuInSe{sub 2} films. It comprises analyses of the surface morphology and reconstruction, electronic band structure as well as hetero-junctions relevant to photovoltaic applications. Therefore, especially the aspect of stoichiometry variation from the CuInSe{sub 2} to the copper-deficient defect phases was considered. Preparation and analysis was completely performed under ultra-high vacuum conditions in order to ensure the investigation of well-defined samples free of contaminants. For some of the analysis techniques, single-crystalline samples are indispensable: They allow for the determination of surface periodicity by low-energy electron diffraction (LEED). In combination with concentration depth profiling by angle-resolved x-ray photoemission, to types of surface reconstructions could be distinguished for the near-stoichiometric CuInSe{sub 2}(112) surface. In the copper-rich case, it is stabilized by Cu{sub In} anti-site defects and on the indium-rich side by 2 V{sub Cu} defects, as predicted by surface total energy calculations by Jaffe and Zunger. Both configurations correspond to a c(4 x 2) reconstruction of the zinc blende type (111) surface. For the defect compound CuIn{sub 3}Se{sub 5}, a sphalerite order of the surface was found, which points at a weakening or absence of the chalcopyrite order in the bulk of the material. The unusual stability of the (112) surface could also be proven by comparison with the reconstruction and surface order of (001) and (220) surfaces. The results from surface analysis were used to measure the valence band structure of the epitaxial samples by synchrotron-based angle-resolved photoelectron spectroscopy. The CuInSe{sub 2}(001) surface gives access to the high symmetry directions {Gamma}-T and {Gamma}-N of momentum space. By contrasting the data obtained for the stoichiometric surface with the copper-poor defect compound, a reduction of the

    The study attempts to understand how dying from cancer is portrayed by five movies produced in Hollywood between 1993 and 2006. Based on the cultural studies and their post-structuralism version and supported by the notions of discourse and subjectivity, as proposed by philosopher Michel Foucault, we suggest one of the possible readings of the movie picture corpus. We assess how the movie picture discourse acts as a cultural pedagogy that produces ways of seeing dying with cancer: immortalizing the healthy body image, silencing death, taking care of the dead body and, finally, accepting death. Our proposal is intended to stimulate reflections that may contribute to care and education in nursing.

    Full Text Available Modewoorde het ons deesdae oorgenoeg in die Christelike sedeleer en hulle kan nogal verwarring stig. U moet my vergun om met u te spreek oor een so ’n modewoord nl „verskuiwing’’ in die moraal. Dis nogal ’n mooi woord, wat so dikwels gebruik word op baie terreine en tog meer wil aandui as maar net ’n veranderde sienswyse, ’n wysiging in opvattinge of nuwe riglyne wat al gangbaar geword het in die praktyk. Die begrip wil eintlik die ewolusionêre gang beklemtoon, want dit is dan eintlik net die ou norme wat effens anders bekyk word of nie meer so nou geneem of dik onderstreep word nie. Die verskuiwing beteken dan dat alles nog dieselfde bly, net die posisie of plek het verander. Verskuiwing beteken tog plekverandering of plekwisseling en dan sekerlik nie in die sin dat die plekke ver uitmekaar lê nie. Verskuiwing beteken net maar vlak langs die vorige te staan kom. As dit dan ’n beter plek is, is dit ewolusie, ontwikkeling, verbetering.

    Full Text Available Proanthocyanidins have a series of heteroflavan-3-ols, (+-catechin/(−-epicatechin units, which are linked through a single B-type linkage and a doubly linked A-type linkage. Recently, we have performed the structural characterization of seed shells of the Japanese horse chestnut and fruits of blueberry and cranberry. The molecular sizes of them were higher in the order of blueberry > cranberry > seed shells of the Japanese horse chestnut between the respective fractions. For the analysis of terminal and extension units in those proanthocyanidins, the isolated fractions were subjected to the thiolytic cleavage of the B-type linkages using 1-dodecanethiol, and the resulting degradation products were identified by ultraperformance liquid chromatography coupled with electrospray-ionization mass spectrometry. These analyses provided fast and good resolution of the degradation products and revealed higher proportions of A-type linkages compared with B-type linkages in both isolated fractions in the order of the seed shells > cranberry > blueberry. Moreover, the isolated fractions with higher molecular sizes and those more abundant in the proportions of A-type linkages were found to be more effective in the inhibition of pancreatic lipase activity. The results suggest that A-type highly polymeric proanthocyanidins are promising for the attenuation of lipid digestion as dietary supplements.

    Three experimental research designs investigating candidate materials and processes involved in protective die surface coating procedures by sputter deposition, using ion beam technologies, are discussed. Various pre-test results show that none of the coatings remained completely intact for 15,000 test cycles. The longest lifetime was observed for coatings such as tungsten, platinum, and molybdenum which reduced thermal fatigue, but exhibited oxidation and suppressed crack initiation only as long as the coating did not fracture. Final test results confirmed earlier findings and coatings with Pt and W proved to be the candidate materials to be used on a die surface to increase die life. In the W-coated specimens, which remained intact on the surface after thermal fatigue testing, no oxidation was found under the coating, although a few cracks formed on the surface where the coating broke down. Further research is planned.

    B-type natriuretic peptide has been extensively studied in patients with cardiovascular disease, but its impact on the perioperative outcome of patients with cyanotic congenital heart defects is still unclear. We assessed the perioperative changes in B-type natriuretic peptide levels and their correlation with preoperative factors and clinical outcomes in a large homogenous group of patients with tetralogy of Fallot undergoing definitive repair at a tertiary care center. A prospective study was undertaken in the cardiac operating room and intensive care unit at a single institution; 250 patients with tetralogy of Fallot undergoing intracardiac repair under cardiopulmonary bypass were studied. B-type natriuretic peptide levels were taken at 3 time points and correlated with clinical variables. Baseline B-type natriuretic peptide levels correlated with the degree of cyanosis in all 4 groups. B-type natriuretic peptide levels at 24 h after admission to the intensive care unit correlated with mortality in the adult subset of patients. B-type natriuretic peptide levels > 290 pg mL(-1) in the intensive care unit predicted an increased probability of adverse clinical outcomes. We demonstrated a rise in serum B-type natriuretic peptide levels in patients with tetralogy of Fallot undergoing definitive repair on cardiopulmonary bypass. B-type natriuretic peptide levels may be monitored to identify patients with cyanosis at increased risk of an augmented inflammatory response to cardiopulmonary bypass. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Full Text Available Die opvatting van die suiwere regstaat bring sy vraagstukke mee wanneer dit in verband gebring word met die leer van die soewereiniteit in eie kring. Laasgenoemde leer wortel in die geloof dat God die mens roep tot diens aan Hom, en dat die mens vry moet wees om ten opsigte van alle lewensaspekte God na die hoogste mate te kan dien. Hierdie verskeidenheid van aspekte is deur dr. A. Kuyper en sy volgelinge gesistemati- seer tot menslike verbande en lewenskringe, elk met ’n be- paalde sfeer waarin ander kringe nie mag inmeng nie. Elkeen is dan soewerein binne sy eie kring. Met verwysing na die staat is dan gespreek van die staatstaak as synde die hand- hawing van die reg, en omdat die staat in toenemende mate hom veral in die latere tyd ook besig gehou het met bedrywig- hede wat nouliks as van juridiese aard beskou kan word, is daar die onderskeid gemaak tussen die primêre en sekundêre taak van die staat. Die sistematiek van die wetsidee, deur prof. Dooyeweerd ontwikkel, waar die staat sy bestemmingsfunksie in die regsaspek vind, het vanselfsprekend geen plek vir so 'n dualistiese staatstaak nie, en die oplossing is deur sommige daarin gesoek om sulke staatsoptrede te vertolk as hebbende wel betrekking op die regsgemeenskap of die regsverkeer. Staatsondernemings soos paaie, spoorweë, spellingreëling, ens. word dan beskou as noodsaaklik vir die instandhouding van die regsgemeenskap en regsverkeer. Tereg wys A. M. Donner1 daarop dat so ’n vertolking eintlik neerkom op ’n oorspanning van die regsbegrip. Hy self sien dan die staatstaak in vrede- of orde-handhawing, wat in die eerste plaas wel regshandha- wing veronderstel. Onder orde word dan alles verstaan wat noodsaaklik is vir die gladde verkeer in die ontwikkelingsgang van die regsgemeenskap. Die wese van die staat het dan vol- gens hom te doen met reg, maar sy taak is meer as suiwere regshandhawing. Wat onrus verwek en die orde versteur, moet uit die openbare lewe verwyder word, en die

    Full Text Available In Ou Egipte is mummifikasie met uitgebreide reseksie of uitsnyding van organe geassosieer, maar geen kennis is geneem van die morfologie van die brein nie. Griekse skrywers van die sesde en vyfde eeue v.C. het die brein aanvanklik gesien as die setel van intelligensie, die orgaan van sensoriese waarneming en gedeeltelik die oorsprong van sperma. Pneuma het ’n belangrike rol in breinfunksie gespeel. Hippokrates was die eerste om die brein te beskryf as ’n dubbele orgaan, wat met harsingvlies (meninges bedek, funksioneel van pneuma afhanklik en vertolker van begrip is. Tydgenote soos Plato, Aristoteles en Diokles het tot die beskrywing bygedra, maar laasgenoemde twee het beweer dat die hart die middelpunt van intelligensie is en nie die brein nie. Gedurende die laaste helfte van die vierde eeu v.C. is disseksie van die menslike liggaam tydelik aan die mediese skool van Alexandrië toegelaat en het dit tot merkwaardige vooruitgang in die begrip van die menslike anatomie en fisiologie gelei.

    Nanolime and a phosphate-based chelating agent were used to synthesize B-type carbonated apatite. Developed Rietveld refinement strategies allowed one to determine process yield, product crystallinity as well as structural (unit cell) and microstructural (size, strain) parameters.

    OPSOMMING: Navorsing op die gebied van die metaleksikografie het oor die laaste paar dekades 'n betekenisvolle fokusverbreding ondergaan. Die aanvanklike fokus was veral op die woordeboekinhoud. Mettertyd het die fokus verskillende woordeboekstrukture ingesluit en tans val leksikografiese funksies binne die bestek van metaleksikografiese navorsing. Al drie hierdie komponente van die leksikografie is ter sake vir die beplanning en samestelling van gebruiker-gedrewe woordeboeke. In hierdie artikel word aangetoon dat die vertrekpunt in die beplanning van 'n nuwe woordeboek nie in die eerste plek 'n bestaande woordeboek moet wees nie. Die tei-kengebruiker moet die vertrekpunt van die hele leksikografiese proses uitmaak. Dit moet lei tot die vasstelling van leksikografiese funksies, die keuse van leksikografiese data en die bepaling van die relevante woordeboekstrukture. Hierdie strukture moet die data op so 'n manier aanbied dat die gebruiker in staat is om 'n optimale onttrekking van inligting te bereik. Terselfdertyd moet die leksikografiese funksies van die woordeboek probleemloos vervul kan word.

  20. Prevalence of psychiatric diagnoses in individuals who die by suicide or attempt suicide in China based on independent structured diagnostic interviews with different informants.

    Many individuals who die by suicide or attempt suicide have no pre-existing psychiatric record. In these cases determination of the presence of mental illness at the time of the suicidal act depends on diagnostic interviews with different informants, but the reliability of such interviews is unknown. To address this issue, the current study from northern China conducted independent diagnostic interviews (by different psychiatrists) with a co-resident family member and another associate of 151 suicide decedents, with 120 individuals who attempted suicide, and with two proxy informants for each suicide attempter. In the suicide decedent group, 56% of interviews with family members and 50% with other associates resulted in one or more psychiatric diagnosis; the concordance (kappa) of these two respondents for the presence of any current psychiatric disorder, any mood disorder and any other psychiatric disorder were 0.35, 0.32 and 0.41, respectively. In the suicide attempt group, 47% of interviewers with suicide attempters, 31% with family members, and 15% with other associates resulted in a psychiatric diagnosis; the concordance for any current psychiatric disorder, any mood disorder and any other psychiatric disorder between the interview with the suicide attempter and the combined result of the two separate proxy informant interviews were 0.31, 0.34 and 0.39, respectively. We conclude that the concordance of the presence and type of psychiatric diagnosis of individuals with suicidal behavior based on independent structured interviews by psychiatrists with different informants is low to fair and that using multiple informants will increase the identification of psychiatric disorders.

    Full Text Available The sdB-type close binaries are believed to have experienced a common-envelope phase and may evolve into cataclysmic binaries (CVs. About 10% of all known sdB binaries are eclipsing binaries consisting of very hot subdwarf primaries and low-mass companions with short orbital periods. The eclipse profiles of these systems are very narrow and deep, which benefits the determination of high precise eclipsing times and makes the detection of small and close-in tertiary bodies possible. Since 2006 we have monitored some sdB-type eclipsing binaries to search for the close-in substellar companions by analyzing the light travel time effect. Here some progresses of the program are reviewed and the formation of sdB-type binary is discussed.

The Dhammanungune Model served as foundation for the design of the Strength of the Psychological Contract Questionnaire which consists of two scales namely, a needs expectation scale and a needs fulfilment expectation scale. The items of each scale have been formulated in the manner that ensures that the respondent reacts consecutively to two instructions namely, (a the level of the expectation and (b the importance of the expectation. This questionnaire was administered together with the Organisational Commitment Questionnaire to two population groups within the military environment.

    2011-11-01

    The temperature magnetic phase diagrams of the dimorphic HoSi compound were studied by neutron diffraction. The sample comprises 35.5% CrB- ( Cmcm) and 64.5% FeB-type ( Pnma) of structure. Both phases order antiferromagnetically below TN=25 K and undergo first-order magnetic transitions at Tic=16.5 K. Their T-phase diagrams comprise a low temperature ( LT) 2.7 K- Tic and a high temperature ( HT) range Tic- TN with distinct wave vectors. The LT magnetic ordering of the CrB-type HoSi with the wave vector q1=(1/2, 0, 1/2) corresponds to a uniaxial magnetic structure, with the Ho moments along the shortest axis c. At 2.7 K the ordered moment value is 8.6(2) μ B/Ho atom. The HT ordering, described by the wave vector q2=( q2 x, 0, q2 z) with a T-variable length, corresponds to an amplitude modulated structure. The magnetic ordering of the FeB-type HoSi requires two symmetry independent vectors q3=(0, q3 y, q3 z) for the LT- and q4=( q4 x, q4 y, 0) for the HT range. Both vectors correspond to sine wave modulated structures with the Ho magnetic moments confined along the shortest axis b. The q3 vector has an almost invariable length vs. T close to ≈(0, 9/17, 1/11). At 2.7 K the amplitude of the wave is 10.9(1) μ B/Ho atom. At Ticq3 jumps to the wave vector q4=( q4 x, q4 y, 0) with a T-variable length. At 17 K q4=(0.092(1), 0.538(3), 0). Around Tic there is a narrow coexistence range of the q3 and q4 competing phases. Various models are discussed and compared with the isomorphic RSi ( R=rare earth) compounds counterparts of HoSi, a comparison that has led us to briefly review the magnetic structures available in the literature for this interesting class of compounds.

Ich lehne mich dabei an Jacques Rancière, Slavoj Žižek, Chantal Mouffe, Mustafa Dikeç, Alain Badiou und andere Kritiker jenes zynischen Radikalismus an, der dafür gesorgt hat, dass eine kritische Theorie und eine radikale politische Praxis ohnmächtig und unfruchtbar vor jenen entpolitisierenden Gesten stehen, die in der polizeilichen Ordnung des zeitgenössischen neoliberalen Spätkapitalismus als Stadtentwicklungspolitik [urban policy] und städtische Politik [urban politics] gelten.

  6. Assisted Dying & Disability.

    Science.gov (United States)

    Riddle, Christopher A

    2017-07-01

    This article explores at least two dominant critiques of assisted dying from a disability rights perspective. In spite of these critiques, I conclude that assisted dying ought to be permissible. I arrive at the conclusion that if we respect and value people with disabilities, we ought to permit assisted dying. I do so in the following manner. First, I examine recent changes in legislation that have occurred since the Royal Society of Canada Expert Panel on End-of-Life Decision-Making report, published in this journal. I suggest that these changes are likely to only strengthen opposition to assisted dying from disability rights activists and people with disabilities. Second, I focus on respect for people with disabilities and in particular, respect for their autonomy and decision-making abilities. Third, I explore the opposition to assisted dying that focuses on risk and the vulnerability of people with disabilities. Here I suggest that this risk ought not to be of special concern. Ultimately, I conclude that upholding respect for the disabled requires the legalization of assisted dying, rather than the denial of access in a misguided effort to protect people with disabilities. © 2017 John Wiley & Sons Ltd.

    Full Text Available T.T. Cloete se oeuvre word onder andere gekenmerk deur fyn waarneming van ’n mistieke vervlegtheid in die skepping. Dit word op vele maniere ontgin en geïnterpreteer. Die poëtiese potensiaal van die vrou, in uiteenlopende gestaltes, is een van die sentrale temas waardeur die digter hieraan vorm gee. In die kunstige, bibliofiele uitgawe Uit die wit lig van my land gesny val die lig op die vrou se kreatiewe rol in die groter skepping wat haar onder andere identifiseer as haarveer vir digterlike insig en vormgewing. Vrou (alternatief Anna Perenna, universele moeder, is nie slegs draer van die lewenskiem wat tot gees transendeer nie, maar sy funksioneer as ligbron (’sonvrou’ wat selfs kosmiese insig verwesenlik. Dit raak meervoudige vorms en patrone waarin die mens ingeweef is in die universele hologram van lewe. Vir die digter is hierdie patroonvorming vergelykbaar met die maak van Persiese tapyte waarvan die patrone vasgelê is in die geheue van voorouers, en oorgedra word na opeenvolgende geslagte. In dié verkenning word digterlike transendering ontgin as ’n proses waarin die kleurvolheid van lewe en dood in en deur individuele sowel as universele vroulikheid geïnspireer word.

Die hepatosietrangskikking vertoon as lobules, met die koorde van hepatosiete wat vanaf ’n sentrale vene uitradieer en met mekaar anastomaseer. Indiwiduele lewerlohules vertoon nie duidelike grense nie, maar enkele duidelike triades word wel in die lewer van O. mossambicus aangetref. Die hepatosiete bevat ’n enkele ronde kern met ’n duidelike nukleolus en die growwe endoplasmiese retikula kom in twee of meer rye om die kerne en teen die selgrense van die hepatosiete voor. Die ander sitoplasmiese organelle kom verspreid in die hepatosietsitoplasma voor. Die eksokriene pankreasselle is om die portale venes gesetel. Die kerne van hierdie selle is rond en is hasaal in die kubies- tot silindervormige selle gelee. ’n Goedontwikkelde growwe endoplasmiese retikulum — vesikulêr, tubulêr en sirkulêr in vorm — en sektretoriese granules wat apikaal in die sel gelee is, kom voor.

    Full Text Available OBJECTIVES:This study aimed to investigate the clinical correlation between angiographic coronary atherosclerosis and N-terminal pro-B-type natriuretic peptide along with other known correlated factors.METHODS:In total, 153 patients with a diagnostic hypothesis of stable angina, unstable angina or acute myocardial infarction were classified as group A (patients with angiographically normal coronary arteries or group B (patients with angiographic coronary atherosclerosis. The two groups were analyzed with respect to the following factors: gender, age, body mass index, abdominal circumference, smoking, diabetes mellitus, arterial hypertension, early family history of atherosclerosis, statin use, the presence of metabolic syndrome, clinical presentation and biochemical factors, including cholesterol, creatinine and fibrinogen plasma concentrations, monocyte counts and N-terminal pro-B-type natriuretic peptide.RESULTS:Univariate analyses comparing the two groups revealed that group B patients more frequently had diabetes, used statins and had systolic dysfunction, N-terminal pro-B-type natriuretic peptide levels ≥250 pg/mL, fibrinogen levels >500 mg/dL and ≥501 monocytes/mm3 compared with group A patients (p<0.05. Nevertheless, multivariate logistic regression analysis demonstrated that the independent predictors of angiographic coronary atherosclerosis were an N-terminal pro-B-type natriuretic peptide level ≥250 pg/mL, diabetes mellitus and increased monocyte numbers and fibrinogen plasma concentration, regardless of the creatinine level or the presence of systolic dysfunction.CONCLUSIONS:An N-terminal pro-B-type natriuretic peptide plasma concentration of ≥250 pg/mL is an independent predictor of angiographic coronary atherosclerosis.

  17. Die vrese van ons vaders

    Anita Cloete

    Full Text Available Die boek fokus op die plek en rol van godsdiensonderrig in skole in die konteks van godsdiensvryheid as deel van 'n demokratiese bestel in Suid-Afrika. Die skrywer betoog teen die behoefte van veral die wit Afrikaner om Christelike godsdiens te gebruik om hulle te onderskei en te isoleer van ander. Christelike godsdiens word dus gebruik om te diskrimineer teen ander wat anders glo of ongelowig is. In dié sin gaan dit dus nie soseer oor die Bybel nie, maar eerder oor die beskerming van godsdiens as magsbasis om die belange van die Afrikaner te beskerm as die sogenaamde uitverkore volk. Godsdiens in skole word dus as 'n politieke wapen gebruik in 'n demokratiese bestel, waar alle mense ongeag ras, klas en godsdiens, regte het wat erken en beskerm moet word. Hierdie poging word ten sterkte teengestaan aangesien dit veral onvanpas is binne 'n demokratiese regeringstelsel.

    Full Text Available The factor structure of Bass's Multifactor Leadership Questionnaire in the South African context. The aim of the study was to determine whether the factor structure of Bass's Multifactor Leadership Questionnaire (MLQ, as a measure of transformational leadership, could be replicated within the South African context. The MLQ was chosen not only because it promised to be a valid and reliable measuring instrument of the construct in question, but also due to the fact that there was an urgent need for such an instrument in the management of human resources within organisations undergoing transformation. The MLQ was administered to 406 subjects within the military context and was subjected to factor analysis and item analysis. The factor analysis yielded three factors, namely transformational leadership, transactional leadership and avoidance of leadership ("laissez faire" leadership. The reliabilities of the scales were determined by means of Cronbach's coefficient alpha, and yielded coefficients of 0,944, 0,736 and 0,803 respectively. The factor structure as conceptualised by Bass (1985 was largely confirmed in the present study. Opsomming Die doel van die studie was om vas te stel of die faktorstruktuur van die Veelfaktorleierskapsvraelys (MLQ van Bass, as maatstafvan transformasionele leierskap, in die Suid-Afrikaanse konteks gerepliseer kon word. Die MLQ is gekies omdat dit belofte inhou as n geldige en betroubare meetinstrument van die onderhawige konstruk, en ook weens die feit dat daar 'n dringende behoefte bestaan aan so n instrument vir gebruik in die bestuur van menslike hulpbronne in organisasies tydens verandering. Die MLQ is op 406 proefpersone binne militêre konteks toegepas, en aan n faktorontleding en n itemontleding onderwerp. Die faktorontleding het drie faktore opgelewer, te wete transformasionele leierskap, transaksionele leierskap en vermyding van leierskap ("laissez faire"-leierskap.

    The influence of terrain on the structure of the atmospheric boundary-layer and the distribution of trace gases during periods of high atmospheric pressure was studied by means of meteorological and air-chemical data collected in September 1992 during the TRACT experiment in the transition area between the upper Rhine valley and the northern Black Forest. The emphasis was on the investigation of the development of the convective boundary layer, the formation of thermally induced circulation systems, and the orographic exchange between the atmospheric boundary layer and the free troposphere. Thanks to the extensive measurements, phenomena not yet described in literature could be verified by case studies, and processes that had only been established qualitatively could be quantified.

    We have determined projected rotational velocities, v sin i, from Magellan/MIKE echelle spectra for a sample of 136 early B-type stars having large Galactocentric distances. The target selection was done independently of their possible membership in clusters, associations or field stars. We subsequently examined the literature and assigned each star as Field, Association, or Cluster. Our v sin i results are consistent with a difference in aggregate v sin i with stellar density. We fit bimodal Maxwellian distributions to the Field, Association, and Cluster subsamples representing sharp-lined and broad-lined components. The first two distributions, in particular, for the Field and Association are consistent with strong bimodality in v sin i. Radial velocities are also presented, which are useful for further studies of binarity in B-type stars, and we also identify a sample of possible new double-lined spectroscopic binaries. In addition, we find 18 candidate Be stars showing emission at Hα.

    Chromium nitride coatings for the surface modified die casting molds with various ICP powers have been prepared using ICP assisted magnetron sputtering. The applied ICP power was varied from 0 to 300 W. The deposited coatings were characterized post-deposition using X-ray diffractometry (XRD) and atomic force microscopy (AFM). Single CrN phased coatings with nano-grain sized (< 20 nm) were identified. The corrosion resistance and hardness of each coating were evaluated from potentiost at and nanoindentator. Superior corrosion protective coatings in excess of 20 GPa were deposited with assistance of ICP plasma during sputtering.

  9. An Einstein Observatory SAO-based catalog of B-type stars

    1992-01-01

    About 4000 X-ray images obtained with the Einstein Observatory are used to measure the 0.16-4.0 keV emission from 1545 B-type SAO stars falling in the about 10 percent of the sky surveyed with the IPC. Seventy-four detected X-ray sources with B-type stars are identified, and it is estimated that no more than 15 can be misidentified. Upper limits to the X-ray emission of the remaining stars are presented. In addition to summarizing the X-ray measurements and giving other relevant optical data, the present extensive catalog discusses the reduction process and analyzes selection effects associated with both SAO catalog completeness and IPC target selection procedures. It is concluded that X-ray emission, at the level of Lx not less than 10 exp 30 ergs/s, is quite common in B stars of early spectral types (B0-B3), regardless of luminosity class, but that emission, at the same level, becomes less common, or nonexistent, in later B-type stars.

    The aim of this study was to determine whether N-terminal pro-B-type natriuretic peptide (NT-proBNP) can predict impending brainstem encephalitis, pulmonary edema, pulmonary hemorrhage, cardiopulmonary failure, and death in children with severe enterovirus 71 (EV71)-associated hand, foot, and mouth disease (HFMD). Plasma NT-proBNP levels of 282 children with severe EV71-associated HFMD were measured. NT-proBNP levels were significantly higher in patients with elevated blood glucose (>7.8 mmol/l) and increased white blood cell counts (>14×10 9 /l). HFMD patients who had no complications had significantly lower NT-proBNP values than patients who died or had complications (pdisease in the intensive care unit. Serum NT-proBNP values ≥1300pg/ml on admission could be indicative of circulatory failure and increased mortality. Copyright © 2016 The Author(s). Published by Elsevier Ltd.. All rights reserved.

    . The impact of risk of bias from lack of blinding of outcome assessment and high attrition levels was examined by restricting analyses to only low 'Risk of bias' studies. Authors' conclusions In patients with heart failure low-quality evidence showed a reduction in heart failure admission with NP-guided treatment while low-quality evidence showed uncertainty in the effect of NP-guided treatment for all-cause mortality, heart failure mortality, and all-cause admission. Uncertainty in the effect was further shown by very low-quality evidence for patient's quality of life. The evidence for adverse events and cost of treatment was low quality and we were unable to pool results. B-type natriuretic peptide-guided treatment for heart failure patients Review question We aimed to discover whether using B-type natriuretic-guided treatment or a health plan alone is more effective for managing patients with heart failure. Background Heart failure is a complex condition that occurs when the heart does not pump blood effectively enough to meet the needs of the body. It is caused by a range of diseases that impair the structure and function of the heart and may result in breathlessness, fatigue and fluid retention. People with heart failure are frequently users of general practice and hospitals, particularly as inpatients. Furthermore, they have reduced life expectancy, although medicines and other treatments can improve the chance of survival. B-type natriuretic peptide (NP) is a substance produced in the heart. The measurement of NP can be used to indicate the condition of the heart. For some time, NP has been used for diagnosing heart failure and predicting what is likely to happen. We wanted to discover if NP may also offer a way to manage and make the best use of medicines. Study selection and characteristics We carried out a review of all studies and the evidence is current to 15 March 2016. We found 18 studies of NP-guided treatment in which 3660 patients with heart failure

  3. T.T. Cloete en die omdigting van die Psalms

    1996-06-01

    Full Text Available Sedert 1989 is T.T. Cloete saam met ander digters werksaam aan die omdigting van die Psalms - ’n taak wat, soos hy self sê, ’n nuwe dimensie in sy lewe ingedra het, maar ook ’n taak wat buitengewone eise stel: eksegeties en hermeneuties moet die Skrifgegewe in die omdigting met omsigtigheid vertolk word, die struktuurpatrone van die grondtaal moet nie onnodig versteur word nie en die eindproduk moet musikologies en harmonies aanvaarbaar op die oor val. In hierdie opsig is die bestaande Geneefse melodie soms ’n verdere dwangmeester wat die verslengte en die strofebou bepaal. Waar ook die melodie in berekening gebring moet word, moet hierdie ‘ruimte’ sinvol ‘ingevul’ word met Skrifgetroue inhoud. En wat poëties, semanties en taalkundig ‘normaal’ is, is nie altyd singbaar nie - die omdigtings moet uiteindelik in aldagtaal gesing word. Woorde, betekenisnuanses, verse en lettergrepe moet dus letterlik en figuurlik geweeg en getel word.

  4. DIE Deflection Modeling: Empirical Validation and Tech Transfer

    Energy Technology Data Exchange (ETDEWEB)

    R. Allen Miller

    2003-05-28

    This report summarizes computer modeling work that was designed to help understand how the die casting die and machine contribute to parting plane separation during operation. Techniques developed in earlier research (8) were applied to complete a large computational experiment that systematically explored the relationship between the stiffness of the machine platens and key dimensional and structural variables (platen area covered, die thickness, platen thickness, thickness of insert and the location of the die with respect to the platen) describing the die/machine system. The results consistently show that there are many significant interactions among the variables and it is the interactions, more than the individual variables themselves, which determine the performance of the machine/die system. That said, the results consistently show that it is the stiffness of the machine platens that has the largest single impact on die separation.

  11. Dying for Security

    Directory of Open Access Journals (Sweden)

    Bruce Buchan

    2011-03-01

    Full Text Available If political statements and media coverage are any guide, it seems Australians today are dying for security. At no other moment in our history has the spectre of war and terrorism so haunted popular, political and scholarly perceptions of Australia’s colonial past and of its geopolitical future. And yet, debates over colonial war or genocide and contemporary terrorism have been conducted in more or less complete isolation. In this article I argue that our contemporary obsession with ‘security’ is premised on the perennial threat of ‘insecurity’. This is the problem of in/security, and it has played a central role in the development of Western political thought. More importantly, its formulation in Western political thought provided a powerful justification for the violence of the early decades of Australia’s colonisation during which Indigenous Australians could also be said to have been dying for security.

    Die Urknallmaschine, an Austrian film by Gerd Baldauf, narrated by Norbert Frischauf (Alpha Österreich - ORF, 2009).  In CERN’s gigantic complex particles are accelerated to almost the speed of light, brought to collision and made to divide into even smaller particles. Public opinion of CERN’s research is also divided. Sceptics fear that black holes may be created. Might the goal to study the origin of the world lead to its destruction? The Austrian researcher Norbert Frischauf worked at CERN for many years. With his guidance it is possible to explore the world’s largest research centre, get a glimpse of the fascinating work the scientists do there and take a crash course in particle physics. Die Urknallmaschine will be presented on Friday, 25 June from 13:00 to 14:00 in the Main Auditorium. Language: German

    Full Text Available Sigmund Freud se lesing van die klassieke endie Griekse mitologie is goed gedokumenteer. In teenstelling daarmee, het Edward Said selesing van Freud min aandag ontvang. Hierdie artikel stel drie hoofkwessies aan die orde: WatSaid en Freud oor antieke en klassieke Griekse literatuur gedink het en hoe hulle dit gebruikhet; die wyse waarop Said Freud se lesing van die antieke en klassieke wêreld gelees het; diebetekenis van ambivalensie en analogie vir hierdie lesings. Die gevolgtrekking van die artikelis dat daar ʼn noodwendige verwantskap tussen analogie en ambivalensie bestaan. Hoofsaaklikchronologies aangepak, steun hierdie lesing ook op Freud se opvattings oor latentheid enrepressie om aan te toon hoe Said se opvattings oor ambivalensie en analogie verander het. Indie geval van Said, is dit moontlik om sommige van die veranderings toe te skryf aan dieimpak van Bernal se Black Athena, wat hom aangemoedig het om die opvattings van dieantieke Griekse samelewing onderliggend aan Oriëntalisme te heroorweeg, en aan die narratiefwat Bernal geïnspireer het, naamlik Kuhn se The structure of scientific revolutions. Latentheid enrepressie maak dit moontlik om voorgeskiedenisse postuleer. Die artikel ondersoek derhalweook die wyse waarop Freud en Said verplig was om kontinuïteite tussen voorgeskiedenis engeskiedenis, en tussen individuele en massapsigologie te veronderstel.

Die basiese opname van die gebied is dan ook in 1957 voltooi. In die eerste stadiums van kartering is die klassifikasie van die verskillende rotstopes gevolg soos wat dit deur Hall en later Van Eeden gedoen is. Soos die werk gevorder het, is veranderings ingevoer om die klassifikasie aan te pas by plaaslike omstandighede, maar nie almal hiervan het die toets van die tyd deurstaan nie.

  12. Non-farnesylated B-type lamin can tether chromatin inside the nucleus and its chromatin interaction requires the Ig-fold region.

    Lamins are thought to direct heterochromatin to the nuclear lamina (NL); however, this function of lamin has not been clearly demonstrated in vivo. To address this, we analyzed polytene chromosome morphology when artificial lamin variants were expressed in Drosophila endoreplicating cells. We found that the CaaX-motif-deleted B-type lamin Dm 0 , but not A-type lamin C, was able to form a nuclear envelope-independent layer that was closely associated with chromatin. Other nuclear envelope proteins were not detected in this "ectopic lamina," and the associated chromatin showed a repressive histone modification maker but not a permissive histone modification marker nor RNA polymerase II proteins. Furthermore, deletion of the C-terminal lamin-Ig-fold domain prevents chromatin association with this ectopic lamina. Thus, non-farnesylated B-type lamin Dm 0 can form an ectopic lamina and induce changes to chromatin structure and status inside the interphase nucleus.

    This book presents a new method for the design of the precision dies used in cold-forging, extrusion and drawing processes. The method is based upon die expansion, and attempts to provide a clear-cut theoretical basis for the selection of critical die dimensions for this group of precision dies when the tolerance on product diameter (or thickness) is specified. It also presents a procedure for selecting the minimum-production-cost die from among a set of design alternatives. The mathematical content of the book is relatively simple and will present no difficulty to those who have taken basic c

    Starches were isolated from rhizomes of Curcuma longa, Canna edulis and Canna indica and bulbs of Lilium lancifolium, and showed a B-type X-ray diffraction pattern. Their physicochemical properties were investigated and compared. These starches showed significantly different granule morphologies and sizes, but all had eccentric hila. The C. longa starch had the lowest content of amylopectin short branch-chain and branching degree and the highest content of amylopectin long branch-chain, and the L. lancifolium starch the highest content of amylopectin short branch-chain and branching degree and the lowest content of amylopectin long branch-chain among the four starches. The L. lancifolium starch had the lowest resistance to gelatinization, and showed the lowest pasting peak, hot and final viscosities, and the C. longa starch had the highest resistance to gelatinization, and showed the highest pasting hot, final and setback viscosities and the lowest pasting breakdown viscosity. The C. longa and L. lancifolium starches possessed very high and low resistance to hydrolysis and digestion, respectively. The above physicochemical properties would be useful for the applications of B-type starches in food and nonfood industries. Copyright © 2015 Elsevier B.V. All rights reserved.

    There are two accepted mechanisms to explain the origin of runaway OB-type stars: the binary supernova (SN) scenario and the cluster ejection scenario. In the former, an SN explosion within a close binary ejects the secondary star, while in the latter close multibody interactions in a dense cluster cause one or more of the stars to be ejected from the region at high velocity. Both mechanisms have the potential to affect the surface composition of the runaway star. tlusty non-LTE model atmosphere calculations have been used to determine the atmospheric parameters and the C, N, Mg, and Si abundances for a sample of B-type runaways. These same analytical tools were used by Hunter et al. for their analysis of 50 B-type open-cluster Galactic stars (i.e., nonrunaways). Effective temperatures were deduced using the Si-ionization balance technique, surface gravities from Balmer line profiles, and microturbulent velocities derived using the Si spectrum. The runaways show no obvious abundance anomalies when compared with stars in the open clusters. The runaways do show a spread in composition that almost certainly reflects the Galactic abundance gradient and a range in the birthplaces of the runaways in the Galactic disk. Since the observed Galactic abundance gradients of C, N, Mg, and Si are of a similar magnitude, the abundance ratios (e.g., N/Mg) are as obtained essentially uniform across the sample.

  5. Rotation, Emission, & Evolution of the Magnetic Early B-type Stars

    We report the results of the first population study of 51 magnetic early B-type stars, based upon a large database of high-resolution spectropolarimetry assembled by the MiMeS and BinaMIcS collaborations. Utilizing these data, rotational periods were determined for all but 5 of the sample stars. This enabled us to determine dipole oblique rotator model parameters, rotational parameters, and magnetospheric parameters. We find that the ratio of the Alfvén radius to the Kepler corotation radius is highly predictive of whether or not a star displays Hα emission from a Centrifugal Magnetosphere (CM), as expected from theoretical considerations. We also find that CM host stars are systematically younger than the general population, as expected given that CM emission requires rapid rotation and a strong magnetic field, and a strong magnetic field will lead to rapid magnetic braking. We conclude that emission-line magnetic early B-type stars are, almost without exception, strongly magnetized, rapidly rotating, and young.

    1992-08-01

    Death is a theme of central importance in all cultures, but the manner in which it is interpreted varies from society to society. Even so, traditional cultures, including Christian, Hindu and Jain religious traditions, exhibited a positive attitude to death and did not look upon it in a dualistic framework of good vs bad, or desirable vs undesirable. Nor was pessimism the dominant mood in their thinking about death itself. A fundamental paradigm shift occurred in the West in the eighteenth century when death was desacralized and transformed into a secular event amenable to human manipulation. From those early beginnings, dying and death have been thoroughly medicalized and brought under the purview of high technology in the twentieth century. Once death is seen as a problem for professional management, the hospital displaces the home, and specialists with different kinds and degrees of expertise take over from the family. Everyday speech and the religious idiom yield place to medical jargon. The subject (an ageing, sick or dying person) becomes the object of this make-believe yet real world. As the object of others' professional control, he or she loses the freedom of self-assessment, expression and choice. Or, he or she may be expected to choose when no longer able to do so. Thus, not only freedom but dignity also is lost, and lawyers join doctors in crisis manipulation and perpetuation. Although the modern medical culture has originated in the West, it has gradually spread to all parts of the world, subjugating other kinds of medical knowledge and other attitudes to dying and death.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available Morality, the obtrusive and the conditional The secularist (immanentist, historicist and pluralistic nature of current thinking disables the articulation of transcendental conditions for morality. It is ostensibly especially the constancy of a structure for morality, as transcendental condition, for morality that is disputable. However, an aggressive immanentism sees to it that a transcendent origin for morality does not even appear on the agenda of late modern thinkers, which makes the latter probably an equally serious marginalisation of transcendental considerations. In this article the (sometimes unconscious experience of some philosophers that a constant structure for morality obtrudes itself upon us, is highlighted. A further claim is that a similar obtrusion can be observed about a coherent diversity of moral sources (i.e. sources which find themselves in a transcendental position with regard to each other. The “most daring” argument is for a transcendental transcendent origin for morality.

    Full Text Available The relationship between locus of control and the work performance of black marketers in the life assurance industry. The aim of the study was to establish the relationship between locus of control and the work performance of black marketers in the life assurance industry. These constructs were selected by virtue of the lack of empirical research regarding the assumed relationship between them. The Locus of Control Scale of Schepers (1995 was used for measuring locus of control. Work performance was measured by the commission earned per month by the marketer, the number of policies generated by the marketer, as well as the percentage of lapsed policies. The relevant measurements were obtained in respect of a sample of 149 black marketing personnel. The results indicated a modest but statistically significant relationship between external locus of control and the work performance of black marketers. Opsomming Die doel van die studie was om die verband tussen lokus van beheer en die werksprestasie van swart bemarkers in die lewensversekeringsbedryf te bepaal. Hierdie konstrukte is gekies op grond van die gebrek aan empiriese navorsing rakende die veronderstelde verband tussen genoemde konstrukte. Die Lokus van Beheer-vraelys van Schepers (1995 is in die meting van lokus van beheer gebruik. Werksprestasie is aan die hand van kommissie per maand verdien, aantal polisse gegenereer deur 'n bemarker en die persentasie vervalde polisse, gemeet. Die tersaaklike metinge is verkry ten opsigte van 'n steekproef van 149 swart bemarkers. Die resultate toon 'n klein, dog statisties beduidende verband tussen eksterne lokus van beheer en die werksprestasie van swart bemarkers in die lewensversekeringsbedryf.

    To find clinical factors relating with plasma B type natriuretic peptide levels (BNP), early and delayed imagings at rest were done in 104 patients with heart diseases (66 males/38 females, mean age of 65.4 y) after the intravenous injection of 111 MBq of {sup 123}I-MIDI (metaiodobenzylguanidine). Myocardial SPECT synchronized with electrocardiography was also done after 600 MBq of {sup 123}I-MIDI injection. In the same day, BNP was measured. Images were taken with ADAC gamma camera VERTEX-plus of 2-detector type. Log BNP was found related with age, H/M(D) (heart/mediastinum count ratio, delayed) and BMI (body mass index) as well as EF (left ventricular ejection fraction) and since the correlation was more significant than BNP, log BNP was considered to be a more sensitive measure.

The purpose of this article is to review the literature on the utility of BNP and NT-proBNP as biomarkers, with a focus on their role in critical illness and pulmonary diseases. Published articles on BNP and NT-proBNP. Multiple disorders in the intensive care unit cause elevated BNP and NT-proBNP levels, including cardiac diseases, shock, pulmonary hypertension, acute respiratory distress syndrome, acute pulmonary embolism, chronic obstructive pulmonary disease, renal failure, and other conditions. Intensivists and pulmonologists should understand that BNP and NT-proBNP levels might be raised to different degrees not only in heart failure but also in critical illness and various pulmonary diseases; in these situations, BNP and NT-proBNP may also serve as markers of severity and prognosis.

And then MCNP (v.5) is performed to obtain the minimum thickness of HIC transport package, which meets the dose rate limit for HIC transport package prescribed in Korea Nuclear Law and IAEA Safety Standards for Radioactive Material Transport. In addition, some other analyses are done about the trend of dose rates depending on the thickness of shielding material and distance from the package.

    Since its discovery in 1988, B-type natriuretic peptide (BNP) has been recognized as a powerful cardiovascular biomarker for a number of disease states, specifically heart failure. Concurrent with such a discovery, much effort has been allocated to the precise monitoring of physiological BNP levels. Thus, it can be used to guide the therapy of heart failure and determine the patient's stage of disease. Thus, we discuss in this article BNP as a potent biomarker. Subsequently, we will review the progress of biosensing devices as they could be applied to monitor BNP levels as assays, benchtop biosensors and implantable biosensors. The analytical characteristics of commercially available BNP assays are presented. Still emerging as a field, we define four obstacles that present opportunity for the future development of implantable biosensor: foreign body response, sensor renewability, sensitivity and selectivity.

  7. Accurate defect die placement and nuisance defect reduction for reticle die-to-die inspections

    Die-to-die reticle inspections are among the simplest and most sensitive reticle inspections because of the use of an identical-design neighboring-die for the reference image. However, this inspection mode can have two key disadvantages: (1) The location of the defect is indeterminate because it is unclear to the inspector whether the test or reference image is defective; and (2) nuisance and false defects from mask manufacturing noise and tool optical variation can limit the usable sensitivity. The use of a new sequencing approach for a die-to-die inspection can resolve these issues without any additional scan time, without sacrifice in sensitivity requirement, and with a manageable increase in computation load. In this paper we explore another approach for die-to-die inspections using a new method of defect processing and sequencing. Utilizing die-to-die double arbitration during defect detection has been proven through extensive testing to generate accurate placement of the defect in the correct die to ensure efficient defect disposition at the AIMS step. The use of this method maintained the required inspection sensitivity for mask quality as verified with programmed-defectmask qualification and then further validated with production masks comparing the current inspection approach to the new method. Furthermore, this approach can significantly reduce the total number of defects that need to be reviewed by essentially eliminating the nuisance and false defects that can result from a die-to-die inspection. This "double-win" will significantly reduce the effort in classifying a die-to-die inspection result and will lead to improved cycle times.

  13. The elusive third subunit IIa of the bacterial B-type oxidases: the enzyme from the hyperthermophile Aquifex aeolicus.

    Directory of Open Access Journals (Sweden)

    Laurence Prunetti

    Full Text Available The reduction of molecular oxygen to water is catalyzed by complicated membrane-bound metallo-enzymes containing variable numbers of subunits, called cytochrome c oxidases or quinol oxidases. We previously described the cytochrome c oxidase II from the hyperthermophilic bacterium Aquifex aeolicus as a ba(3-type two-subunit (subunits I and II enzyme and showed that it is included in a supercomplex involved in the sulfide-oxygen respiration pathway. It belongs to the B-family of the heme-copper oxidases, enzymes that are far less studied than the ones from family A. Here, we describe the presence in this enzyme of an additional transmembrane helix "subunit IIa", which is composed of 41 amino acid residues with a measured molecular mass of 5105 Da. Moreover, we show that subunit II, as expected, is in fact longer than the originally annotated protein (from the genome and contains a transmembrane domain. Using Aquifex aeolicus genomic sequence analyses, N-terminal sequencing, peptide mass fingerprinting and mass spectrometry analysis on entire subunits, we conclude that the B-type enzyme from this bacterium is a three-subunit complex. It is composed of subunit I (encoded by coxA(2 of 59000 Da, subunit II (encoded by coxB(2 of 16700 Da and subunit IIa which contain 12, 1 and 1 transmembrane helices respectively. A structural model indicates that the structural organization of the complex strongly resembles that of the ba(3 cytochrome c oxidase from the bacterium Thermus thermophilus, the IIa helical subunit being structurally the lacking N-terminal transmembrane helix of subunit II present in the A-type oxidases. Analysis of the genomic context of genes encoding oxidases indicates that this third subunit is present in many of the bacterial oxidases from B-family, enzymes that have been described as two-subunit complexes.

  14. Maintaining Low Voiding Solder Die Attach for Power Die While Minimizing Die Tilt

    Energy Technology Data Exchange (ETDEWEB)

    Hamm, Randy; Peterson, Kenneth A.

    2015-10-01

    This paper addresses work to minimize voiding and die tilt in solder attachment of a large power die, measuring 9.0 mm X 6.5 mm X 0.1 mm (0.354” x 0.256” x 0.004”), to a heat spreader. As demands for larger high power die continue, minimizing voiding and die tilt is of interest for improved die functionality, yield, manufacturability, and reliability. High-power die generate considerable heat, which is important to dissipate effectively through control of voiding under high thermal load areas of the die while maintaining a consistent bondline (minimizing die tilt). Voiding was measured using acoustic imaging and die tilt was measured using two different optical measurement systems. 80Au-20Sn solder reflow was achieved using a batch vacuum solder system with optimized fixturing. Minimizing die tilt proved to be the more difficult of the two product requirements to meet. Process development variables included tooling, weight and solder preform thickness.

    Polycrystalline samples of double perovskites Ba{sub 2}BOsO{sub 6} (B=Sc, Y, In) were synthesized by solid state reactions. They adopt the cubic double perovskite structures (space group, Fm-3m) with ordered B and Os arrangements. Ba{sub 2}BOsO{sub 6} (B=Sc, Y, In) show antiferromagnetic transitions at 93 K, 69 K, and 28 K, respectively. The Weiss-temperatures are −590 K for Ba{sub 2}ScOsO{sub 6}, −571 K for Ba{sub 2}YOsO{sub 6}, and −155 K for Ba{sub 2}InOsO{sub 6}. Sc{sup 3+} and Y{sup 3+} have the open-shell d{sup 0} electronic configuration, while In{sup 3+} has the closed-shell d{sup 10}. This indicates that a d{sup 0} B-type cation induces stronger overall magnetic exchange interactions in comparison to a d{sup 10}. Comparison of Ba{sub 2}BOsO{sub 6} (B=Sc, Y, In) to their Sr and Ca analogues shows that the structural distortions weaken the overall magnetic exchange interactions. - Graphical abstract: Magnetic properties of osmium double perovskites Ba{sub 2}BOsO{sub 6} (B=Sc, Y, In) were studied.

    Full Text Available Larger and larger proportions of aluminium castings, especially those produced by the die casting process, can be observed during recent years in the automotive industry, house-hold articles and others. In case of the automotive industry, apart from the traditional elements produced by the die pressure method such as engine blocks or crank shaft bedplates, aluminium is displacing steel from structural parts of cars (‘body in white’. The current state and development directions of the structural solutions of cold-chamber die castings are analysed in this paper. These solutions drive the prospective development of these machines and die casting technology. The focus is mainly on essential functional systems such as: hydraulic drives of closing and locking units, as well as pressing in die machines of known companies present on the European market.

    This paper deals with numerical optimization of open die forging of large metallic ingots made by casting implying risk of defects, e.g. central pores. Different material hardening properties and die geometries are combined in order to investigate, which geometry gives rise to maximum closure...... of a centreline hole in a single compression operation. Friction is also taken into account. The numerical analysis indicates that a lower die angle of approximately 140o results in the largest centreline hole closure for a wide range of material hardening. The value of optimum die angle is not influenced...... by friction, which was found only to change the degree of centreline porosity closure in case of small lower die angle....

    2014-06-01

    Full Text Available Hot forging dies providing high productive performance reduce production costs. The lifetime of the dies is expressed by the number of forgings (production cycle produced before being rejected by the presence of a failure mechanism, associated with unacceptable dimensions and or geometry of the end product or even breakage of the dies. One of the failure mechanisms of hot forging dies is thermal fatigue, caused by cyclic heating and cooling. A subroutine, based on the work of Maim and Norstrom [1], was developed for the DEFORM 2D numerical software, using the finite element method, in order to predict die regions susceptible to thermal fatigue. The use of adequate coefficients for the description of the heat transfer phenomena allowed the validation of the proposed subroutine.

    Full Text Available “African thinking,” “African thought,” and “African philosophy.” These phrases are often used indiscriminately to refer to intellectual activities in and/or about Africa. This large field, which sits at the crossroads between analytic philosophy, continental thought, political philosophy and even linguistics is apparently limitless in its ability to submit the object “Africa” to a multiplicity of disciplinary approaches. This absence of limits has far-reaching historical origins. Indeed it needs to be understood as a legacy of the period leading to African independence and to the context in which African philosophy emerged not so much as a discipline as a point of departure to think colonial strictures and the constraints of colonial modes of thinking. That the first (self-appointed exponents of African philosophy were Westerners speaks volumes. Placide Tempels but also some of his predecessors such as Paul Radin (Primitive Man as Philosopher, 1927 and Vernon Brelsford (Primitive Philosophy, 1935 were the first scholars to envisage this extension of philosophy into the realm of the African “primitive.” The material explored in this article – Statues Also Die (Marker, Resnais, and Cloquet, Bantu Philosophy (Tempels, The Cultural Unity of Negro Africa (Cheikh Anta Diop, and It For Others (Duncan Campbell - resonates with this initial gesture but also with the ambition on part of African philosophers such as VY Mudimbe to challenge the limits of a discipline shaped by late colonialism and then subsequently recaptured by ethnophilosophers. Statues Also Die is thus used here as a text to appraise the limitations of African philosophy at an early stage.  The term “stage,” however, is purely arbitrary and the work of African philosophers has since the 1950s often been absorbed by an effort to retrieve African philosophizing practices before, or away from, the colonial matrix. This activity has gained momentum and has been

  14. Biodesign of a renal-protective peptide based on alternative splicing of B-type natriuretic peptide.

    Alternative RNA splicing may provide unique opportunities to identify drug targets and therapeutics. We identified an alternative spliced transcript for B-type natriuretic peptide (BNP) resulting from intronic retention. This transcript is present in failing human hearts and is reduced following mechanical unloading. The intron-retained transcript would generate a unique 34 amino acid (aa) carboxyl terminus while maintaining the remaining structure of native BNP. We generated antisera to this carboxyl terminus and identified immunoreactivity in failing human heart tissue. The alternatively spliced peptide (ASBNP) was synthesized and unlike BNP, failed to stimulate cGMP in vascular cells or vasorelax preconstricted arterial rings. This suggests that ASBNP may lack the dose-limiting effects of recombinant BNP. Given structural considerations, a carboxyl-terminal truncated form of ASBNP was generated (ASBNP.1) and was determined to retain the ability of BNP to stimulate cGMP in canine glomerular isolates and cultured human mesangial cells but lacked similar effects in vascular cells. In a canine-pacing model of heart failure, systemic infusion of ASBNP.1 did not alter mean arterial pressure but increased the glomerular filtration rate (GFR), suppressed plasma renin and angiotensin, while inducing natriuresis and diuresis. Consistent with its distinct in vivo effects, the activity of ASBNP.1 may not be explained through binding and activation of NPR-A or NPR-B. Thus, the biodesigner peptide ASBNP.1 enhances GFR associated with heart failure while lacking the vasoactive properties of BNP. These findings demonstrate that peptides with unique properties may be designed based on products of alternatively splicing.

    Full Text Available Recently The New York Times reported: “VERY ILL CHILDREN TOLD OF DISEASE; Leukemia Patients at N.I.H. Not Shielded From Truth. . . . A child should always be told the truth, even when he has an incurable disease such as leukemia, according to two researchers who interviewed 51 children hospitalized at the National Cancer Institute, Bethesda, Maryland, for treat¬ment of leukemia.” This kind of news item reflects the growing concern among researchers and public about matters which touch on morality as much as on the technical aspects of medi¬cine. The rapidly increasing proportion of elderly people in the American population presents a range of personal and social questions; not the least is how they view their newly won longevity (often including anticipated years of chronic disease as well as their attitudes toward death. In consequence, many geriatric specialists are beginning to study American attitudes toward death, while others, spurred on by what seems a sense-less prolonging of life within hospital walls by medical tech¬nology run wild, are raising questions about death and dying in American life.

    2016-03-01

    Full Text Available Objective: To explore the significance of B-type natriuretic peptide (BNP in the diagnosis of diastolic heart failure (DHF. Methods: A total of 50 patients with DHF who were admitted in our hospital from September, 2014 September, 2015 were included in the study and served as DHF group. Moreover, 30 patients with non heart failure were served as the control group. Color Doppler ultrasonic diagnostic apparatus was used to measure LEVDD, LAD, and LVEF. The four-chamber-view pulse Doppler was used to detect E and Ea. The average value was taken and E/Ea was calculated. The full automatic electrochemiluminescence immunoassay was used to determine the plasma BNP level. Results: With the aggravation of cardiac function grading, LAD, LEVDD, E, and E/Ea were significantly increased, but LVEF and Ea were significantly reduced when compared with the control group. BNP level in DHF group was significantly higher than that in the control group. With the increasement of NYHA grading, BNP level was gradually increasing, and the comparison between the two groups was statistically significant. Conclusions: BNP level is increasing with the increasement of NYHA grading, which is of great significance in the early diagnosis of DHF, and the hazard estimation, and is characterized by simple operation and high accuracy; therefore, it deserves to be widely recommended in the clinic.

    The Barkhausen noise and magnetic viscosity in sintered and melt-quenched needles of anisotropic NdFeB-type magnets are examined. In the sintered magnet, the time integral of the Barkhausen signal during magnetic viscosity is shown to correlate with the change in the bulk magnetisation as measured using a vibrating sample magnetometer. This is in contrast with similar measurements on soft magnetic materials by Tebble et al., where the magnetisation change, as estimated from the time integral of the Barkhausen noise, was significantly less than that measured by magnetometric techniques. The activation volume in each of the two materials is estimated from measurements of the coefficient of magnetic viscosity, S v , and in the case of the sintered magnet is shown to be up to 13 orders of magnitude smaller that the largest Barkhausen volumes associated with the demagnetisation process. The magnitude of the Barkhausen volumes are indicative of magnetisation processes involving instabilities in the magnetisation of clusters of grains. It was not possible to identify heterogeneities in the microstructural or magnetic topology in these materials which would account for the magnitudes of the observed Barkhausen jumps. (orig.)

    This paper reports, for the first time, the use of electron backscattered diffraction (EBSD) to study orientation in sintered NdFeB type magnets. The magnetic properties of NdFeB magnets are greatly improved if a strong crystallographic texture is firstly achieved, namely, the direction of the c-axis is along the direction of magnetization. A systematic survey of sample preparation techniques showed that samples that were mechanically polished and then etched gave the most reliable EBSD data. Analyses were made using both fully automated EBSD scans and by EBSD measurements taken after manual movement of the beam. The EBSD results are presented as secondary electron SEM micrographs, orientation images and 001 pole figures. For the selection of grains investigated, the deviation of the c-axis was shown to be between 10 degrees and 30 degrees from the ideal [001]//magnetization direction. It is demonstrated that EBSD is a valuable tool for characterizing the microstructure and texture relationships and for assessing the performance of the processing routes of NdFeB magnets.

    Nitrogen (N) is considered as a main limiting factor in plant growth, and nitrogen losses through denitrification can be responsible for severe decreases in plant productivity. Recently, it was demonstrated that Fallopia spp. is responsible for biological denitrification inhibition (BDI) through the release of unknown secondary metabolites. Here, we investigate the secondary metabolites involved in the BDI of Fallopia spp. The antioxidant, protein precipitation capability of Fallopia spp. extracts was measured in relation to the aerobic respiration and denitrification of two bacteria (Gram positive and Gram negative). Proanthocyanidin concentrations were estimated. Proanthocyanidins in extracts were characterized by chromatographic analysis, purified and tested on the bacterial denitrification and aerobic respiration of two bacterial strains. The effect of commercial procyanidins on denitrification was tested on two different soil types. Denitrification and aerobic respiration inhibition were correlated with protein precipitation capacity and concentration of proanthocyanidins but not to antioxidant capacity. These proanthocyanidins were B-type procyanidins that inhibited denitrification more than the aerobic respiration of bacteria. In addition, procyanidins also inhibited soil microbial denitrification. We demonstrate that procyanidins are involved in the BDI of Fallopia spp. Our results pave the way to a better understanding of plant-microbe interactions and highlight future applications for a more sustainable agriculture. © 2015 Society for Applied Microbiology and John Wiley & Sons Ltd.

  20. Endothelial Expression of Scavenger Receptor Class B, Type I Protects against Development of Atherosclerosis in Mice

    Full Text Available The role of scavenger receptor class B, type I (SR-BI in endothelial cells (EC was examined in several novel transgenic mouse models expressing SR-BI in endothelium of mice with normal C57Bl6/N, apoE-KO, or Scarb1-KO backgrounds. Mice were also created expressing SR-BI exclusively in endothelium and liver. Endothelial expression of the Tie2-Scarb1 transgene had no significant effect on plasma lipoprotein levels in mice on a normal chow diet but on an atherogenic diet, significantly decreased plasma cholesterol levels, increased plasma HDL cholesterol (HDL-C levels, and protected mice against atherosclerosis. In 8-month-old apoE-KO mice fed a normal chow diet, the Tie2-Scarb1 transgene decreased aortic lesions by 24%. Mice expressing SR-BI only in EC and liver had a 1.5 ± 0.1-fold increase in plasma cholesterol compared to mice synthesizing SR-BI only in liver. This elevation was due mostly to increased HDL-C. In EC culture studies, SR-BI was found to be present in both basolateral and apical membranes but greater cellular uptake of cholesterol from HDL was found in the basolateral compartment. In summary, enhanced expression of SR-BI in EC resulted in a less atherogenic lipoprotein profile and decreased atherosclerosis, suggesting a possible role for endothelial SR-BI in the flux of cholesterol across EC.

  1. Kelvin-Helmholtz instabilities and their application to B-type variables

    A Kelvin-Helmholtz instability, formed from the differential rotation in the narrow region between the core and envelope, is proposed as a promising mechanism responsible for the excitation of pulsations in B-type variables (53 Per variables and β Cep stars), in which the unstable inertia wave resulting from this instability resonates with an eigenmode of the non-radial oscillation of the whole star. The degeneracy of the two frequencies is found to be expected at any evolutionary stage of a star. The equations for a Kelvin-Helmholtz instability have been formulated for the stellar case, and in the cylindrical configuration limit, the necessary condition for instability and characteristics of the instability have been discussed. It is shown that prograde modes with large /m/ for a given l are excited in almost all cases; which seems to agree with observations. The back reaction of the excited modes on the differential rotation is discussed in these stars, and it is pointed out that the differential rotation can be significantly affected by this effect in a short time.

    To determine whether b-type natriuretic peptide (BNP) concentrations can guide treatment of patent ductus arteriosus (PDA) to reduce the number of indomethacin doses without increasing morbidity. Prospective, randomised, controlled trial. Single-centre referral neonatal intensive care unit. Infants with echocardiographic diagnosis of PDA. Infants with congenital heart disease or renal insufficiency were excluded. BNP measurement and echocardiography were performed in all subjects before and after indomethacin treatment. The investigational group had BNP concentrations measured 12 and 24 h after the first dose (before the 2nd and 3rd doses of indomethacin). Indomethacin dosing was withheld in the BNP-guided group if the 12 or 24 h BNP concentrations were found to be gender or indomethacin prophylaxis. Median baseline and 48 h BNP concentrations did not differ between the groups (0 h: 500 vs 542 pg/ml; 48 h: 85 vs 126 pg/ml; control and BNP-guided groups, respectively). During primary indomethacin treatment, the BNP-guided group received fewer doses of indomethacin than controls (70 vs 88 doses, p<0.05). The rate of PDA ligation, intestinal perforation and chronic lung disease did not differ between groups. BNP-guided treatment reduced the number of primary indomethacin doses. There was no increase in PDA persistence or associated morbidity.

    Giulia Montanari

    2010-11-01

    Full Text Available In this work—his PhD thesis—Christian VON SCHEVE examines the connections between emotions and social structures. From a sociological viewpoint and taking into account findings from the neurosciences and cognitive psychology, he seeks to answer the question of how, on the one hand, are emotions susceptible to influences from the social environment, and on the other, do they generate social structure themselves. By presenting many empirical findings, the author succeeds in exemplifying relevant mechanisms. Although one cannot expect to find definitive answers to these questions, VON SCHEVE'S work offers a rich contribution to discussions on the micro-macro link, as well as questions of human agency. At present, research on emotions by social scientists is an emerging field, which this review seeks to illustrate. Another aim of this review is to show which discussions can be enriched by debating the elements of this work. URN: http://nbn-resolving.de/urn:nbn:de:0114-fqs1101287

    In this paper, we study the role non-adaptivity plays in maintaining dynamic data structures. Roughly speaking, a data structure is non-adaptive if the memory locations it reads and/or writes when processing a query or update depend only on the query or update and not on the contents of previously...... read cells. We study such non-adaptive data structures in the cell probe model. This model is one of the least restrictive lower bound models and in particular, cell probe lower bounds apply to data structures developed in the popular word-RAM model. Unfortunately, this generality comes at a high cost...

    This volume introduces readers to the structured conflict analysis as a tool of social science research and uses this instrument exemplarily to analyze systematically and on a broad basis the various conflicts that are associated with Iran both domestically and in foreign policy - beyond popular stereotypes such as the ''bomb''. The 13 contributions draw a complex picture of the conflicts with and in Iran and reflect the various aspects of these conflicts from different perspectives and at a high methodological and theoretical level. The nuclear program is examined, inter alia through the eyes of four major theories of International Relations. In addition, the analyses are concerned with the regional security dimension, the relationship USA-Iran, the role of national preferences, and the effect of national processes to the Iranian foreign policy.

    Purpose: To flesh out the ESUR guidelines for the standardized interpretation of multiparametric magnetic resonance imaging (mMRI) for the detection of prostate cancer and to present a graphic reporting scheme for improved communication of findings to urologists. Materials and Methods: The ESUR has recently published a structured reporting system for mMRI of the prostate (PI-RADS). This system involves the use of 5-point Likert scales for grading the findings obtained with different MRI techniques. The mMRI includes T2-weighted MRI, diffusion-weighted imaging, dynamic contrast-enhanced MRI, and MR spectroscopy. In a first step, the fundamentals of technical implementation were determined by consensus, taking into account in particular the German-speaking community. Then, representative images were selected by consensus on the basis of examinations of the three institutions. In addition, scoring intervals for an aggregated PI-RADS score were determined in consensus. Results: The multiparametric methods were discussed critically with regard to implementation and the current status. Criteria used for grading mMRI findings with the PI-RADS classification were concretized by succinct examples. Using the consensus table for aggregated scoring in a clinical setting, a diagnosis of suspected prostate cancer should be made if the PI-RADS score is 4 or higher ({>=} 10 points if 3 techniques are used or {>=} 13 points if 4 techniques are used). Finally, a graphic scheme was developed for communicating mMRI prostate findings. Conclusion: Structured reporting according to the ESUR guidelines contributes to quality assurance by standardizing prostate mMRI, and it facilities the communication of findings to urologists.

    Lignite has a key role to play in the transformation of the energy system due to its specific structural features in terms of industry, company history, policy, economics, the environment and regional structures. Understanding these structural features of the German lignite industry is an important requirement for classifying the significance of the lignite industry up to now and for the redesigning of this industrial sector. From these environmental, economic and regulatory structural characteristics, which are interwoven in a variety of ways, the incentives arise for the mining and power plant operators to react to energy price signals or energy policy steering. The aim of this research study is to define these structural features, to compile comprehensively the basic data and information that is not always transparently available, to understand the interactions, to enable the navigation of issues that are partly very complex, and to classify into the long-term developments that are especially important for political and social processes. In 2016 approx. 12 percent of German primary energy consumption was met using lignite. At the same time, lignite has the highest carbon dioxide (CO2) emissions of the fossil fuels; it currently accounts for approx. 19 percent of Germany's total greenhouse gas emissions as well as approx. 46 percent of the total CO2 emissions of the electricity sector. As a result of the mining of lignite and its conversion into electricity, substantial adverse impacts beyond the entry of greenhouse gases into the Earth's atmosphere arise for other environmental media. These impacts include half of Germany's mercury emissions, approx. a third of its sulfur dioxide emissions and approx. a tenth of its nitrogen oxide emissions. Lignite mining in open-cast mines takes up a substantial amount of landscape and soil and requires huge interventions in the water balance. Relatively high costs arise for the recultivation and rehabilitation

    In situ transmission electron microscopy magnetizing experiments combined with Lorentz magnetic microscopy in Fresnel endash Foucault modes were used to characterize the magnetic structure of die-upset, high energy-product hard magnets Nd 13.75 Fe 80.25 B 6 and Pr 13.75 Fe 80.25 B 6 . Experimental observations indicate a well-aligned grain structure and quasiperiodic nonaligned open-quotes extended defectclose quotes layers transverse to press direction. The local remanence of the open-quotes defectclose quotes layers is far from saturation when the external field is removed. The layers are enriched with inclusions of approximate composition Nd 7 Fe 3 , generally with a polygonal shape, and are associated with the original ribbon interfaces. They may be responsible for a high coercivity mechanism, since the motion of reverse domains can be impeded by these layers, even when they are nucleated. Thus, a delayed nucleation of reversed domains seems to be a limiting factor for magnetization reversal and coercivity force. Both Lorentz magnetic imaging and high-resolution microscopy highlight the role of magnetocrystalline anisotropy for domain wall-grain boundary interactions and pinning. Local remanence was estimated directly from magnetic moment sensitive Foucault images. copyright 1999 American Institute of Physics

    Full Text Available Background : Plasma B-type natriuretic peptide (BNP is the diagnostic tool for acute heart failure (AHF.This natriu­retic peptide level depends on renal function, through renal metabolism and excretion. Therefore we examined the effect ofrenal impairment on plasma BNP level during diagnosis of AHF.Objective: The objective of the study was to assess the effect of renal dysfunction on plasma BNP level and to determine appropriate cutoff value of plasma BNP to diagnose the patients of AHF with renal insufficiency.Methods: This cross sectional analytical study was conducted in the Depart­ment of Biochemistry Bangabandhu Sheikh Mujib Medical University (BSMMU. The study was done among 90 AHF patients selected from cardiology emergency department during the period of July 2012 to June 2013. After enrollment plasma BNP concentration was measured and eGFR was estimated from serum creatinine by the four parameter Modifica­tion of Diet and Renal Disease (MORD equation and then grouped into two groups on the basis of empirical cut off value of eGFR 60 ml/min/1.73 m2Results: In this study a significant negative correlation was found between plasma BNP evel and eGFR (P<0.001 , with higher BNP levels observed as eGFR declined. The optimal BNP cutoff value for diagno­sis of AHF patients with renal insufficiency was 824 pg/ml. At this cutoff level AHF with renal insufficiency could be diagnosed with sensitivity and specificity of 84% and 71 %, respectively.Conclusions: By adjusting the cutoff value, plasma BNP can be used to diagnose AHF with renal insufficiency with an acceptable sensitivity and specificity.

    To determine whether serum N-terminal pro-B-type natriuretic peptide (N-BNP), a biomarker of myocardial wall stress, is specific to acute heart failure (HF) in patients hospitalized with stroke. Case-control study. Tertiary hospital, Neurosciences Critical Care Unit and Stroke Unit. Consecutive patients with acute ischemic or hemorrhagic stroke who were evaluated for HF. None. Cases and controls were classified, respectively, as patients with or without HF, defined according to modified Framingham criteria. Seventy-two patients were evaluated, 39 with ischemic stroke, 22 with aneurysmal subarachnoid hemorrhage (SAH), and 11 with intracerebral hemorrhage (ICH). Thirty-four patients (47%) met criteria for HF, and 47 patients (65%) had systolic or diastolic left ventricular (LV) dysfunction on echocardiogram. Serum N-BNP was measured a median of 48 h following the onset of stroke and was increased (> 900 pg/ml) in 56 patients (78%), with higher levels in non-survivors (11898 +/- 12741 vs 4073 +/-5691; p = 0.001). In a multiple regression model, N-BNP elevation was not independently associated with HF (OR 5.4, 95% CI 0.8-36.0, p = 0.084). At a cut-off of 900 pg/ml, the sensitivity of N-BNP for HF was 94%, specificity 37%, positive predictive value (PPV) 57%, and negative predictive value (NPV) 88%. For systolic or diastolic LV dysfunction, the sensitivity of N-BNP was 89%, specificity 44%, PPV 75%, and NPV 69%. These results demonstrate that N-BNP elevation is not specific to HF or LV dysfunction in patients with acute ischemic stroke, SAH, and ICH.

    Rejection is one of the major causes of mortality following pediatric heart transplant. B-type natriuretic peptide (BNP) has been studied as a method for the diagnosis of acute rejection, especially in adult patients undergoing heart transplant. To correlate serum BNP levels with acute rejection as diagnosed by endomyocardial biopsy in patients of the pediatric heart transplant group. A total of 50 BNP samples were collected from 33 children in the postoperative period of heart transplant, and data on age, gender, skin color, blood group, immune panel, follow-up time after transplant, functional class, immunosuppressive regimen used and number of rejections were analyzed. Thirty three children with median age of 10.13 years were analyzed; of these, 54% were females and 78% were Caucasians. BNP levels were determined at a mean time from transplant of 4.25 years. Nine episodes of rejection were diagnosed in eight patients (27%) by means of endomyocardial biopsy; of these, three were grade 3A, five were grade 2, and one had humoral rejection. At the moment of biopsy, most patients were asymptomatic. The mean serum BNP level was 77.18 pg/ml, with 144.22 pg/ml in the group with rejection and 62.46 pg/ml in the group without rejection, with p = 0.02. Asymptomatic children can present acute rejection in the postoperative period of heart transplant. Serum BNP levels show a statistically significant difference in the group with rejection and thus can be an additional method in the diagnosis of cardiac rejection.

    Data regarding the value of B-type natriuretic peptide (BNP) measurements in infants with a single-ventricle (SV) physiology are lacking. This analysis aimed to describe the BNP level changes in infants with an SV physiology before and after superior cavopulmonary connection (SCPC) surgery. Levels of BNP were measured by a core laboratory before SCPC (at 5.0 ± 1.6 months) and at the age of 14 months during a multicenter trial of angiotensin-converting enzyme inhibition therapy for infants with SV. Multivariable longitudinal analysis was used to model the associations between BNP levels and three sets of grouped variables (echocardiography, catheterization, growth). Multivariable analysis was performed to assess associations with patient characteristics at both visits. Associations between BNP levels and neurodevelopmental variables were investigated at the 14 month visit because neurodevelopmental assessment was performed only at this visit. The BNP level was significantly higher before SCPC (n = 173) than at the age of 14 months (n = 134). The respective median levels were 80.8 pg/ml (interquartile range [IQR], 35-187 pg/ml) and 34.5 pg/ml (IQR, 17-67 pg/ml) (p SCPC and in 21 subjects (16 %) at the age of 14 months. In the 117 patients who had BNP measurements at both visits, the median BNP level decreased 32 pg/ml (IQR, 1-79 pg/ml) (p SCPC surgery (p SCPC surgery (p = 0.04), and a lower Bayley psychomotor developmental index (p = 0.02). The levels of BNP decreases in infants with SV from the pre-SCPC visit to the age of 14 months. A higher BNP level is associated with increased ventricular dilation in systole, increased AV valve regurgitation, impaired growth, and poorer neurodevelopmental outcomes. Therefore, BNP level may be a useful seromarker for identifying infants with SV at risk for worse outcomes.

    The rotational and magnetic properties of many magnetic hot stars are poorly characterized, therefore the Magnetism in Massive Stars and Binarity and Magnetic Interactions in various classes of Stars collaborations have collected extensive high-dispersion spectropolarimetric data sets of these targets. We present longitudinal magnetic field measurements for 52 early B-type stars (B5-B0), with which we attempt to determine their rotational periods Prot. Supplemented with high-resolution spectroscopy, low-resolution Dominion Astrophysical Observatory circular spectropolarimetry, and archival Hipparcos photometry, we determined Prot for 10 stars, leaving only five stars for which Prot could not be determined. Rotational ephemerides for 14 stars were refined via comparison of new to historical magnetic measurements. The distribution of Prot is very similar to that observed for the cooler Ap/Bp stars. We also measured v sin i and vmac for all stars. Comparison to non-magnetic stars shows that v sin i is much lower for magnetic stars, an expected consequence of magnetic braking. We also find evidence that vmac is lower for magnetic stars. Least-squares deconvolution profiles extracted using single-element masks revealed widespread, systematic discrepancies in between different elements: this effect is apparent only for chemically peculiar stars, suggesting it is a consequence of chemical spots. Sinusoidal fits to H line measurements (which should be minimally affected by chemical spots), yielded evidence of surface magnetic fields more complex than simple dipoles in six stars for which this has not previously been reported; however, in all six cases, the second- and third-order amplitudes are small relative to the first-order (dipolar) amplitudes.

    Full Text Available Aim To estimate the effects of forced repeated swimming stress on BNP serum levels in rats. Methods Adult male Wistar rats weighting between 280-330 g were divided into two groups: control group (n =8 and stress group (n =8. Rats in the stress group were exposed to forced swimming stress daily, for 7 days. The rats were forced to swim in plastic tanks (90 cm wide, 120 cm deep containing tap water (temperature ca. 25°C. The depth of water was 40 cm. Duration of each swimming session progressively increased from 10 minutes on the irst day to 40 minutes on days 6 and 7. Rats were sacriiced and blood was drawn from abdominal aorta for BNP analysis immediately after the last swimming session. B-type natriuretic serum level was determined by ELISA method using RAT BNP-32 kit (Phoenix Pharmaceutical Inc.. Results There was no statistically signiicant difference between mean BNP serum level in the stress group after the swimming period (0.81±0.14 ng/ml as compared to the unstressed group of rats (0.8 ±0.08ng/ml. After the swimming period mean body weight slightly decreased in the stress group in comparison with values before stress period (296.3 g vs.272.8 g, but this difference was not statistically signiicant. The stress period had no inluence on food intake in the stress rat group. Conclusion The workload consisting of 40-minutes long swimming session is not suficient to provoke BNP release from myocardium in rats.

    To investigate the associations of sleep duration with all-cause mortality, glycemic control, and other clinical parameters of patients with type 2 diabetes. From April 2013 to December 2015, we conducted a retrospective cohort study. Study participants were divided into three groups according to their sleep duration. Multiple regression analysis and Cox proportional hazards analysis were performed to assess the independent associations of sleep duration with clinical parameters and all-cause mortality. We enrolled 1233 patients who were then followed for 860 ± 264 days. During the follow-up period, 20 patients (1.6%) died. Sleep duration inversely associated with plasma B-type natriuretic peptide levels (β = -0.203, p = 0.012) in short (<7 h) sleepers, whereas it was positively associated with hemoglobin A1c levels (β = 0.156, p = 0.021) in long (≥9 h) sleepers. Moreover, Cox proportional hazard analysis revealed that short sleep duration was a significant predictor of all-cause mortality (hazard ratio = 0.473; confidence interval 0.248-0.905, p = 0.024). Short sleep duration may serve as a prognostic indicator of mortality in Japanese patients with type 2 diabetes and may increase cardiovascular stress. Adequate sleep is essential for the management of type 2 diabetes. Copyright © 2017 Elsevier B.V. All rights reserved.

  8. B-type olivine fabric induced by low temperature dissolution creep during serpentinization and deformation in mantle wedge

    The B-type olivine fabric (i.e., the [010] axes subnormal to foliation and the [001] axes subparallel to the lineation) has been regarded as an important olivine fabric for interpreting global trench-parallel S-wave polarization in fore-arc regions. However, strong serpentinization and cold temperature environment in the mantle wedge should inhibit development of the B-type olivine fabric that requires high temperature to activate solid-state plastic deformation. Here we report fabrics of olivine and antigorite generated at low temperatures (300-370 °C) during serpentinization in a fossil mantle wedge of the Val Malenco area, Central Alps. Olivine in the serpentine matrix develops a pronounced B-type fabric, while antigorite in the same matrix displays a strong crystallographic preferred orientation (CPO) with the (001) planes and the [010] axes subparallel to foliation and lineation, respectively. The following evidence leads to the conclusion that the B-type olivine fabric results from dissolution creep assisted by grain boundary sliding (GBS) and grain rotation, rather than solid-state plastic deformation: (1) serpentinization took place at low temperatures and a fluid-enriched environment, ideal for dissolution-precipitation creep; (2) the voids and zigzag boundaries along the interface between antigorite and olivine suggest a fluid dissolution reaction; (3) the primary coarse olivine develops a nearly random fabric, indicating the B-type fabrics in the fine-grained olivine may not be inherited fabrics. These results document for the first time the B-type olivine CPO formed by dissolution creep at low temperatures during serpentinization and provide a mechanism to reconcile petrofabric observations with geophysical observations of trench parallel fast S-wave seismic anisotropy in fore-arc mantle wedge regions.

  9. Osteoblast and osteoclast responses to A/B type carbonate-substituted hydroxyapatite ceramics for bone regeneration.

    The influence of carbonate substitution (4.4 wt%, mixed A/B type) in hydroxyapatite ceramics for bone remodeling scaffolds was investigated by separately analyzing the response of pre-osteoblasts and osteoclast-like cells. Carbonated hydroxyapatite (CHA) (Ca 9.5 (PO 4 ) 5.5 (CO 3 ) 0.5 (OH)(CO 3 ) 0.25 -CHA), mimicking the chemical composition of natural bone mineral, and pure hydroxyapatite (HA) (Ca 10 (PO 4 ) 6 (OH) 2 -HA) porous ceramics were processed to obtain a similar microstructure and surface physico-chemical properties (grain size, porosity ratio and pore size, surface roughness and zeta potential). The biological behavior was studied using MC3T3-E1 pre-osteoblastic and RAW 264.7 monocyte/macrophage cell lines. Chemical dissolution in the culture media and resorption lacunae produced by osteoclasts occur with both HA and CHA ceramics, but CHA exhibits much higher dissolution and greater bioresorption ability. CHA ceramics promoted a significantly higher level of pre-osteoblast proliferation. Osteoblastic differentiation, assessed by qRT-PCR of RUNX2 and COLIA2, and pre-osteoclastic proliferation and differentiation were not significantly different on CHA or HA ceramics but cell viability and metabolism were significantly greater on CHA ceramics. Thus, the activity of both osteoclast-like and osteoblastic cells was influenced by the carbonate substitution in the apatite structure. Furthermore, CHA showed a particularly interesting balance between biodegradation, by osteoclasts and chemical dissolution, and osteogenesis through osteoblasts' activity, to stimulate bone regeneration. It is hypothesized that this amount of 4.4 wt% carbonate substitution leads to an adapted concentration of calcium in the fluid surrounding the ceramic to stimulate the activity of cells. These results highlight the superior biological behavior of microporous 4.4 wt% A/B CHA ceramics that could beneficially replace the commonly used HA of biphasic calcium phosphates for future

    Full Text Available Die benaming „Kliniese Kindersielkunde” is nog onbekend en gevolglik betreklik onbemind. Dit is in 1951 die eerste keer gebruik. Die werk van die Kliniese Kindersielkunde is egter so oud as die werk van die algemene Kliniese Sielkunde, waarvan die geskiedenis gewoonlik teruggevoer word tot die begin van sielkundige toetsing vroeg in die tagtigerjare. Tot ’n aansienlike mate is hierdie vroeë werk op kinders uitgevoer, bv. dié van Galton en later die van Binet en Simon. Witmer het in 1896 die eerste sielkundige kliniek geopen en het ook die term „Kliniese Sielkunde” ingevoer; die meerderheid van sy pasiënte was egter ook kinders. Tot voor die Tweede Wêreldoorlog was klinies-sielkundige werk hoofsaaklik op kinders toegespits. Sedertdien het die kliniese sielkundige tot ’n belangrike mate toegetree tot die gebied van die diagnose en terapie van psigiese afwykings by volwassenes, tot so ’n mate dat in die gedagtes en geskrifte van baie werkers die terrein van die Kliniese Sielkunde byna tot werk met volwassenes beperk word.

    In the present paper the author reports on the continuation of an OEKOR part project in which he had undertaken a chemical characterisation of emissions from domestic brown coal combustion. On the basis of a partitioning by land use of the Greater Leipzig region he initiated long-term observations of local pollution levels for the various structural types of land. The aim of the work was to facilitate a comprehensive analysis of local air quality in terms of VOC levels. The current concern about VOCs results from the toxicological risk they have been proven to pose to the human organism and from their relevance to the chemistry of the atmosphere (e.g., as precursors of ground-level ozone and other oxidising agents). The task to be accomplished was broken down into the following main steps: Development and trial of a sampling and analysis method for determining an as wide a spectrum of environmental VOCs as possible; elaboration of a measuring strategy for obtaining results of high representativeness and power; installation and operation of pollution monitoring sites in selected structural types of area characteristic of Leipzig; execution of measuring campaigns of several weeks each at selected sites during both winter and summer periods.

    Full Text Available The general aim of the study is to investigate the different attitudes and perceptions of middle level managers with regard to sources of job satisfaction, sources which contribute to job dissatisfaction, and to job stress. In this regard it was decided to make use of triangulation by which qualitative and quantitative research methods are used. Thematic analysis is used on the qualitative level to identify the possible sources of job satisfaction, dissatisfaction and job stress. This method is quantitatively supported by a determination of the frequencies and percentages of subject responses by means of semi structured interviews. On the qualitative level it was found that the experience of success is rated as the most important source of job satisfaction and that interpersonal relationships are the most significant source of job dissatisfaction. Finally it seems that work expectations/ demands appear to be the major source of job stress. Opsomming Die algemene doelstelling van die studie is om ondersoek in te stel na die verskillende houdings en persepsies van middelvlak-bestuurders rakende werkstevredenheid, sowel as die bronne wat bydra tot werkstres en werksontevredenheid. In dié verband is besluit om van triangulasie gebruik te maak. Op die kwalitatiewe vlak word tematiese analise gebruik om potensiële bronne van werkstevredenheid, ontevredenheid en werkstres te identifiseer. Hierdie metode word verder kwantitatief ondersteun deur ‘n bepaling van frekwensies en persentasies van subjekte se reponse wat uit semi-gestruktureerde onderhoude verkry is. Op die kwalitatiewe vlak blyk dit dat die ervaring van sukses die grootste bron van werkstevredenheid is en dat interpersoonlike verhoudings die bron is wat die meeste bydra tot ontevredenheid. Verder blyk dit dat werksverwagtinge/-eise die grootste bron van werkstres is.

    Background and objectives Monitoring N-terminal pro–B-type natriuretic peptide (NT-proBNP) may be useful for assessing cardiovascular risk in dialysis patients. However, its biologic variation is unknown, hindering the accurate interpretation of serial concentrations. The aims of this prospective cohort study were to estimate the within- and between-person coefficients of variation of NT-proBNP in stable dialysis patients, and derive the critical difference between measurements needed to exclude biologic and analytic variation. Design, setting, participants, & measurements Fifty-five prevalent hemodialysis and peritoneal dialysis patients attending two hospitals were assessed weekly for 5 weeks and then monthly for 4 months between October 2010 and April 2012. Assessments were conducted at the same time in the dialysis cycle and entailed NT-proBNP testing, clinical review, electrocardiography, and bioimpedance spectroscopy. Patients were excluded if they became unstable. Results This study analyzed 136 weekly and 113 monthly NT-proBNP measurements from 40 and 41 stable patients, respectively. Results showed that 22% had ischemic heart disease; 9% and 87% had left ventricular systolic and diastolic dysfunction, respectively. Respective between- and within-person coefficients of variation were 153% and 27% for weekly measurements, and 148% and 35% for monthly measurements. Within-person variation was unaffected by dialysis modality, hydration status, inflammation, or cardiac comorbidity. NT-proBNP concentrations measured at weekly intervals needed to increase by at least 46% or decrease by 84% to exclude change due to biologic and analytic variation alone with 90% certainty, whereas monthly measurements needed to increase by at least 119% or decrease by 54%.

    During the last two decades a new interest has emerged in the structure of the letter to the Philippians, leading to a variety of text oriented studies, which have more or less confirmed the unity of the letter. This article contributes to these studies by making a thought-structure analysis of the text of Philippians. This analysis, which takes the grammatical relations within the text as point of departure, but proceeds to a study of the more implicit markers of structure, such as repetition and figures of speech, reveals that the thoughts in the letter body of Philippians are arranged in a triangle pattern. In this pattern Philippians 1:27-30 serves as a “table of contents”, which is expanded upon in the rest of the letter body (2:1-3:21. In a subtle way the main elements of the “table of contents” are echoed in Philippians 4:1-9, resulting in an “inclusio”-pattern. These patterns of thought structure of Philippians provide further support for theories in favour of the unity of the letter.

    Full Text Available The scavenger receptor class B, type I (SR-BI, is a member of the CD36 superfamily comprising transmembrane proteins involved in mammalian and fish lipid homeostasis regulation. We hypothesize that this receptor plays an important role in Macrobrachium nipponense lipid metabolism. However, little attention has been paid to SR-BI in commercial crustaceans. In the present study, we report a cDNA encoding M. nipponense scavenger receptor class B, type I (designated as MnSR-BI, obtained from a hepatopancreas cDNA library. The complete MnSR-BI coding sequence was 1545 bp, encoding 514 amino acid peptides. The MnSR-BI primary structure consisted of a CD36 domain that contained two transmembrane regions at the N- and C-terminals of the protein. SR-BI mRNA expression was specifically detected in muscle, gill, ovum, intestine, hepatopancreas, stomach, and ovary tissues. Furthermore, its expression in the hepatopancreas was regulated by dietary lipid sources, with prawns fed soybean and linseed oils exhibiting higher expression levels. RNAi-based SR-BI silencing resulted in the suppression of its expression in the hepatopancreas and variation in the expression of lipid metabolism-related genes. This is the first report of SR-BI in freshwater prawns and provides the basis for further studies on SR-BI in crustaceans.

    Full Text Available In higher eukaryotes, nuclear envelope (NE disassembly allows chromatin to condense and spindle microtubules to access kinetochores. The nuclear lamina, which strengthens the NE, is composed of a polymer meshwork made of A- and B-type lamins. We found that the B-type lamin (Lam is not fully disassembled and continues to localize along the spindle envelope structure during Drosophila male meiosis I, while the A-type lamin (LamC is completely dispersed throughout the cytoplasm. Among the nuclear pore complex proteins, Nup107 co-localized with Lam during this meiotic division. Surprisingly, Lam depletion resulted in a higher frequency of cytokinesis failure in male meiosis. We also observed the similar meiotic phenotype in Nup107-depleted cells. Abnormal localization of Lam was found in the Nup-depleted cells at premeiotic and meiotic stages. The central spindle microtubules became abnormal and recruitment of a contractile ring component to the cleavage sites was disrupted in Lam-depleted cells and Nup107-depleted cells. Therefore, we speculate that both proteins are required for a reinforcement of the spindle envelope, which supports the formation of central spindle microtubules essential for cytokinesis in Drosophila male meiosis.

  3. Framework for simulation-driven design of stamping dies considering elastic die and press deformations

    Pilthammar, Johan; Wall, Johan; Sigvant, Mats

    2017-10-01

    Sheet metal forming (SMF) simulations are used extensively throughout the development phase of industrial stamping dies. In these SMF simulations, the die and press are normally considered as rigid. Previous research has however shown that elastic deformation in these parts has a significant negative impact on process performance. This paper demonstrates methods for counteracting these negative effects, with a high potential for improved production support and a reduced lead time through a shorter try-out process. A structural finite element model (FE-model) of a simplified die is studied. To account for elastic deformation, the blankholder surfaces are first virtually reworked by adjusting the nodal positions on the die surfaces attaining a pressure distribution in accordance to the design phase SMF simulations with rigid surfaces. The elastic FE-model with reworked surfaces then represents a stamping die in running production. The die is now assumed to be exposed to changed process conditions giving an undesired blankholder pressure distribution. The changed process conditions could for example be due to a change of press line. An optimization routine is applied to compensate the negative effects of the new process conditions. The optimization routine uses the contact forces acting on the shims of the spacer blocks and cushion pins as optimization variables. A flexible simulation environment using MATLAB and ABAQUS is used. ABAQUS is executed from MATLAB and the results are automatically read back into MATLAB. The suggested optimization procedure reaches a pressure distribution very similar to the initial distribution assumed to be the optimum, and thereby verifying the method. Further research is needed for a method to transform the calculated forces in the optimization routine back to shims thicknesses. Furthermore, the optimization time is relatively long and needs to be reduced in the future for the method to reach its full potential.

    2015-01-01

    This study reports the development of a measurement scale, The Nurses' Involvement in Patients' Dying and Death Scale (NIPDYDS), which fully captures the experiences of nurses caring for patients' dying and death. Potential items were extracted from narrative data gathered systematically and comprehensively from in-depth interviews with nurses engaged in caring for patients' dying and death. Factor analyses revealed four factors, consisting of 40 total items, with two factors related to the positive aspects of the experience (Deep involvement in facing dying and death and Increased competence in facing dying and death) and two factors related to the negative aspects of the experience (Uncertainty and difficulty dealing with dying and death and Accustomed to dying and death). Validity and reliability of the scale were found to be acceptable. The factorial structure of the NIPDYDS was contrasted to Frommelt's (1991) FATCOD (The Frommelt Attitude Toward Care of the Dying Scale), and the usefulness and limitations of the NIPDYDS were discussed.

    Full Text Available Die gevorderde hantering van afwykings van bene en gewrigte, Ortopedie, het in Mesopotamië en veral in antieke Egipte sy ontstaan gehad. Dit was egter die Griekse geneeshere wat in die laat 5de eeu v.C. in die Hippokratiese Korpus ’n merkwaardig doeltreffende samevatting van die ortopediese beroep vasgelê het, waarop vir minstens ’n 1 000 jaar nie beduidend verbeter sou word nie. Gebaseer op die onderskeiding tussen toe en oop frakture en ontwrigtings (lg. met oorliggende velwond, en aansienlik swakker prognose is hierdie afwykings so spoedig moontlik gereduseer (selfs deur middel van meganiese tegnieke, die oorliggende vel met seraatsalf gesmeer en dan met kompresse en verbande geïmmobiliseer. Gedurende die eerste 12 dae is die letsel herhaaldelik weer oopgemaak om die fraktuur of ontwrigting te herbelyn indien nodig. Eers hierna is ferm immobilisasie met onder andere spalke aangebring. Beduidende druk op die letsel is vermy omdat daar geglo is dat dit sepsis en gangreen aanbring. Dit is aanvaar dat genesing 20 dae (by byvoorbeeld voet-, rib- en sleutelbeenfrakture en 40 dae (by been- en bo-armfrakture sou duur. Benewens algemeen geldende prosedures is die spesifi  eke hantering van 18 verskillende frakture en ’n groot aantal ontwrigtings in besonderhede uitgespel. Oor ander ortopediese afwykings soos degeneratiewe artritis en jig verskyn daar min in die Hippokratiese werke, maar later geneeshere in die Romeinse era (bv. Celsus, Soranus, Aretaeus en Galenus het dit wel beskryf. Daar is aanduiding dat die hantering van siektes van gewrigte en bene by die mens (die dissipline van ortopedie in moderne terminologie reeds in antieke Egipte deeglik bestudeer en aangeteken is. 1 Tydens die klassieke era en die Romeinse tyd is beduidende verdere bydraes gelewer. In hierdie studie word die ewolusionêre ontwikkeling van ortopedie as kliniese studierigting in die antieke tyd, onder die loep geneem.

    2017-07-01

    Full Text Available After World War II, the communist party took control of the nation-building process of the newly established Socialist Federal Republic of Yugoslavia. World War II played a major role in the narration and was reinterpreted as the People's Revolution. The union of war veterans took part in this process by influencing federal legislation as well as the setting-up of war graves and memorials. In 1959, the municipality of Mostar decided to build a partisan cemetery, and commissioned the architect Bogdan Bogdanović to build it. Bogdanović planned a vast war cemetery surrounded by a large park area, with the memorial park embedded into the structure of the city. The main axes of the park are oriented towards important urban spots like the old town. Though – or rather precisely because – the monument has a high urbanistic, historic, and artistic value, it has recently been a target of politically motivated attacks.

    Full Text Available Met die 450e herdenking van die Heidelbergse Kategismus as vertrekpunt, word met die huidige en die vorige artikel gepoog om lig te werp op die plek, die rol en die interpretasie van die opstanding van Jesus Christus in veral Sondag 17 en 22, spesifiek in die konteks van twee besondere eras in die Nederduitse Gereformeerde (NG Kerk. In die vorige artikel is allereers ’n bespreking gevoer oor die Heidelbergse Kategismus (HK. Daar is gekyk na die resepsie van die betrokke HK-geloofsartikels in die era van Andrew Murray, spesifiek teen die agtergrond van die negentiende-eeuse liberale teologie in Nederland. In die huidige artikel word soortgelyk gekyk na die resepsie van die betrokke HK-geloofsartikels in die NG Kerk na 2000, teen die agtergrond van die herverskyning van die negentiende-eeuse liberale teologie in die vorm van die Jesus Seminaar, die Nuwe Hervorming en ondersteuners daarvan binne die NG Kerk. Sowel die negentiende-eeuse liberale stryd in die NG Kerk asook die stryd oor die opstanding in die NG Kerk van die eerste dekade van die een-en-twintigste eeu, soos verder in hierdie artikel sal blyk, was gekenmerk deur kontekstueelbepaalde uniekhede. Die gemene deler was dat albei deel was van tye van teologiese vrysinnigheid. In die lig van hierdie bespreking word tot die gevolgtrekking gekom dat die NG Kerk tans, betreffende haar identiteit as gereformeerde kerk waarskynlik in ’n kritieke geloofs- en toekomskrisis verkeer. Dit impliseer kommerwekkende gevolge vir haar Skrifverstaan en getuienis as belydenis en belydende kerk van Jesus Christus en haar toekoms. Alleen duidelike visie, verantwoordelike leierskap en ’n herontdekking van die verlossingskrag van Christus se kruis en opstanding sal herstellende, positiewe en dinamiese oplossings kan bied om sodoende die NG Kerk te red van ’n snelwentelende afwaartse spiraal.

    Full Text Available In hierdie artikel word aandag gevra vir enkele moderne diskoerse in die teologie vandag. Volgens die outeur staan die vrae oor God, Jesus, die mens en die aarde in die sentrum van belangstelling en oorheers dit in ’n groot mate die teologiese debat. Die opkoms van die moderne aggressiewe ateïsme, die wetenskaplike navorsing oor die historiese Jesus, die groeiende vrae oor die mens en die menslike samelewing, asook die dreigende ekologiese krisis op aarde, sorg vir nuwe debatte van ongekende omvang. Die outeur bespreek hierdie debatte oorsigtelik, met kritiek waar nodig, en sluit af met enkele rigtingwysers van wat hy as ‘goeie teologie’ verstaan. In this article attention is paid to some modern discourses in theology today. According to the author the questions about God, Jesus, man and the earth are in the centre of interest and to a large extent dominate the theological debate. The rise of modern aggressive atheism, the scientific research on the historic Jesus, the growing questions about man and human society as well as the threatening ecological crisis on earth, provide new discourses of unparalleled magnitude. The author provides a broad summary of these discourses, with criticism where necessary, and concludes with some indicators of his view what can be called ‘good theology’.

The following aspects are addressed: the origin and content of the Confession of Belhar, the ecclesiastical and theological reaction within the family of Dutch Reformed Churches as well as in the reformed ecumenical world. A critical analysis of the content is made and evaluated, and in con- clusion attention is given to a few options with regard to the place of the Confession of Belhar in the reformed ecumenical world in the future. A comparison between the Three Forms of Unity and the Confession of Belhar shows a definite difference in quality.

    Full Text Available Learning theory basis of andragogy. A cursory glance at andragogy creates the impression that humanistic learning theory plays an all encompassing role in the learner centered approach andragogy espouses. A closer look, however, reveals that Knowles (1973, after having made an intensive study of learning theory, created an extensive framework within which human resource development can take place. The fact that Knowles attracted critique from different areas, led to a need to ascertain the role different learning theories, if any, played in the emergence of andragogy. Having looked at the assumptions displayed by the andragogical approach, as well as a comparison of different learning theories and their connection with andragogy, it became clear that andragogy contains elements of various learning theories in an adapted way. These adaptations resulted in an approach to adult education in which learners are given the opportunity to be part of the learning process in such a way that they themselves contribute to the development which takes place. Opsomming Met 'n eerste oogopslag wil dit voorkom asof humanistiese leerteorie 'n oorheersende rol in die leerdergesentreerde benadering van andragogie speel. By nadere ondersoek blyk dit egter dat Knowles (1973, na 'n deeglike studie van verskillende leerteoretiese beginsels, 'n omvangryke raamwerk geskep het waarbinne, aan die hand van verskeie aangepaste leerteoretiese beginsels, menslike hulpbronontwikkeling kan plaasvind. As gevolg van die feit dat Knowles vanuit verskillende oorde kritiek op die lyf geloop het, is besluit om die rol wat verskillende leerteorieë in andragogie speel, te bestudeer. Dit blyk dat andragogie nie net elemente van verskillende leerteorieë bevat nie, maar dat toepaslike aspekte van die teoriee wat ondersoek is, benut en aangepas is om 'n geintegreerde benadering te bewerkstellig waarin veral volwassene-leerders by leergeleenthede en hulle selfontwikkeling betrek word.

    In a method of hardening pilger dies to provide a hard case containing residual compressive stresses and tough body, the tool steel die is heated to the austenitizing temperature range, followed by selectively removing heat from the die at a predetermined faster rate in the direction of the desired case than the rate of heat removal from the balance of the die, and thereafter tempering the die. The invention provides a fully hardened and tempered case on the working surface of the die and a tough body in the balance of the die, usually of lower hardness. (author)

Andererseits wurden die Unterschiede und Parallelen zwischen parasozialen Beziehungen zu den Stars und orthosozialen Beziehungen aufgezeigt. Im Zusammenhang mit der empirischen Untersuchung bezieht sich die Autorin auf den Uses-and-Gratifications-Approach, wobei die bedürfnissbefriedigenden Wirkungen von Musikkanälen und den dazu gehörigen Popstars im Mittelpunkt stehen. Mit Hilfe des Uses-and-Gratifications-Approach wird angenommen, dass das Konsumieren der Musiksendungen und der Musikstars von den Jugendlichen gezielt zur Befriedigung bestimmter Bedürfnisse eingesetzt wird.The objective of this study is to explore the effects of pop stars on adolescents (aged between 13 and 17. The focus of interest is the question what effect music channels (i.e. video clips from music channels produce and what characteristics are noticeable from the formed relationship between adolescents and pop stars. On the other side, parallels and differences have been drawn between the para-social relationships to pop stars and ortho-social relationships. In connection with empirical study, the author also refers to Uses-and Gratification-Approach where the need satisfying effects of music channels and pop stars are in focus. With the help of Uses-and Gratification-Approach it will be assumed, that aim of watching music channels and therefore pop stars will be pointed toward the gratification of specific needs.

    Full Text Available In die Grieks-Romeinse era het mediese behandeling kenmerkend uit drie elemente bestaan, naamlik regimen (dieet en gesonde leefwyse, geneesmiddels en chirurgie – laasgenoemde alleen toegepas indien regimen en geneesmiddels onsuksesvol was. Bewyse van primitiewe chirurgie dateer terug na die Bronstydperk, en in Homerus se eposse is heelwat vermelding van die chirurgiese hantering van oorlogswonde, met tussenkoms van die gode. Met die koms van empiriese geneeskunde in die 5de eeu v.C. het chirurgie in die Hippokratiese Corpus prominent gefigureer met beduidende bydraes in veral die ortopediese veld en hoofbeserings. Uitbouing van anatomiese en fisiologiese kennis, gebaseer op disseksie van menslike kadawers in Alexandrië vanaf die laat 4de eeu v.C., het chirurgie ’n hupstoot gegee. Teen die Romeinse era vanaf die 2de eeu v.C. het snykundetegnieke (en -instrumente beduidend verbeter, maar is steeds oorwegend deur Griekse geneeshere beoefen. Van geneeshere is steeds verwag om al drie bovermelde terapeutiese modaliteite te bemeester, maar chirurgie het meer aansien verwerf en daar is al meer in onderafdelings van chirurgie soos oogheelkunde, vrouesiektes en verloskunde, blaaskwale en mond- en keelsnykunde gespesialiseer. Militêre geneeskunde was in die Romeinse Ryk ’n belangrike aktiwiteit, en het veral traumachirurgie uitgebou. Betreding van die buik- en toraksholtes was nie meer noodwendig fataal nie, en veeartsenykunde het tot stand gekom. Die eerste beduidende chirurgiehandboek ná die Hippokratiese Corpus is in die 1ste eeu n.C. deur Celsus opgestel. Vanaf die 3de eeu het die chirurgieberoep min vordering gemaak, die beroepstaal het mettertyd van Grieks na Latyn verander en kundigheid is later veral deur Islam-geneeshere na die Middeleeue en later oorgedra.

    We would like to thank Dr. Nozaka for his interest in our work and also for supplying some of the crystal orientation data that we used in our study. He presents a detailed discussion of differences in interpretation between our two studies. The main difference is whether the strong B-type olivine CPO developed as a result of topotactic static growth after breakdown of antigorite (Nagaya et al., 2014) or if it developed due to homoepitaxial growth on a limited number of olivine grains that already showed a general B-type CPO (Nozaka, 2014). In both of our studies static growth of olivine due to the breakdown of antigorite is key in the strengthening or formation of B-type olivine CPO. This conclusion has potentially far reaching implications for the interpretation of mantle seismic anisotropy in subduction zones and is the most important take home message. However, the details of interpretation are also important. In our reply, we focus on what we consider to be the 5 main points of disagreement. We refer to Fig. 1 to explain different microstructural domains.

    Directory of Open Access Journals (Sweden)

    F Venter

    1998-11-01

    Full Text Available The Preamble and Chapter 1 This contribution is intended to be the first installment of a systematic interpretation of the Constitution of the Republic of South Africa 1996.Due to the foundational and repetitive reference in the text to values, regard must constantly be had to those values when this Constitution is interpreted.Even though the preamble does not contain positive norms, is an important interpretive source of the foundations of the Constitution. An important deviation from the preamble of the 1993 Constitution, is that the term Rechtsstaat ("constitutional state" is not employed. The introduction of this notion in South African law and its meaning in general is described. With reference to relevant dicta in recent constitutional cases, the Constitutional Principles in terms of which the 1996 Constitution was formulated and the text of the Constitution itself, it is argued that this is essentially a Rechtsstaat Constitution, but that the divergence in the range of constitutional values creates the danger of the constitutional state floundering in the waters of the social state.Section 1, being the foundational provision, is not unamendable, but it is very tightly entrenched. The most profound values of the Constitution are set out in this compact formulation. The question is inevitably raised whether, where values have to compete for precedence in concrete circumstances, a hierarchy of values must be construed. An analysis of section 1 in the context of other relevant provisions of the Constitution reveals that human dignity is the primary nuclear value of the Constitution, supported by equality and freedom. Democracy, supremacy of the Constitution and the rule of law are structural and procedural values of the Constitution subordinate to the nuclear values and non-racialism and non-sexism are derived values.How it is possible for a constitution to be superior law, as section 2 provides regarding the 1996 Constitution, is analysed

    2014-08-01

    We tested whether the changes in extravascular lung water indexed for ideal body weight could detect weaning-induced pulmonary edema. We also studied the diagnostic value of blood volume contraction indices and B-type natriuretic peptide variations. Prospective study. Twenty-one patients who failed a first spontaneous breathing trial. None. We performed a second 60-minute T-tube spontaneous breathing trial. Before and at the end of spontaneous breathing trial, we recorded pulmonary artery occlusion pressure, the extravascular lung water indexed for ideal body weight, plasma B-type natriuretic peptide level, hemoglobin, and plasma protein concentrations. Weaning-induced pulmonary edema was defined by the association of signs of clinical intolerance and a pulmonary artery occlusion pressure greater than or equal to 18 mm Hg at the end of spontaneous breathing trial. Because some patients performed several spontaneous breathing trial, a primary analysis included all spontaneous breathing trial and a secondary analysis included only the first spontaneous breathing trial of each patient. In primary analysis, 36 spontaneous breathing trials were analyzed, 21 spontaneous breathing trial with weaning-induced pulmonary edema and 15 without. During spontaneous breathing trial, extravascular lung water indexed for ideal body weight increased only in cases with weaning-induced pulmonary edema (25% ± 23%). Plasma protein concentration, hemoglobin concentration, and B-type natriuretic peptide also significantly increased only in cases with weaning-induced pulmonary edema (9% ± 3%, 9% ± 4%, 21% ± 23%, respectively). The areas under the receiver operating characteristics curves to detect weaning-induced pulmonary edema were 0.89 (95% CI, 0.78-0.99) for extravascular lung water indexed for ideal body weight, 0.97 (0.93-1.01) for spontaneous breathing trial-induced changes in plasma protein concentration, 0.96 (0.90-1.01) for changes in hemoglobin concentration, and 0.76 (0

  6. Die stand van wiskundeonderwys in Afrikaanse skole

    Full Text Available Hoërordedenkvaardighede is noodsaaklike basiese vaardighede vir die een-en-twintigste eeu aangesien rekenaars berekeninge en algoritmes baie vinniger en akkurater kan doen as mense. Dit beteken dat skole leerders moet toerus om logies te dink, patrone te ontdek, bewyse te lewer, asook om nieroetineprobleme op te los. Hierdie fasette wat as hoërordedenke geklassifiseer word, is die kern van wiskundige denke en ontwikkeling. Suid-Afrika neem aan verskeie internasionaal vergelykende studies deel. Met behulp van hierdie vergelykende studies kan bepaal word hoe die Afrikaanse wiskundeleerders in Suid-Afrika se prestasie met dié van leerders in ander lande vergelyk en ook wat die tekortkominge in die wiskundeonderwys is. Volgens die 2003-TIMSS-uitslae is die probleem in Afrikaanse skole juis dié vrae wat hoërordedenke vereis. Dit beteken dat die Afrikaanse skole ’n doelbewuste poging sal moet aanwend om hoërordedenke te ontwikkel. Die 1999-TIMSS-videostudie toon dat die lande wat die beste presteer, soos Japan, tydens onderrig meer tyd wy aan die ontwikkeling van begripsvorming en aan die oplos van moeiliker probleme. Die fokus in die presterende lande is op die ontwikkeling van hoërordedenke deur probleemoplossing. Daar word dus minder tyd afgestaan aan herhaling van roetine- of soortgelyke oefeninge wat ’n rekenaar ook kan doen. Die omgekeerde hiervan is ’n tipiese verskynsel in Afrikaanse skole, waar ’n onderwyser byvoorbeeld een of meer voorbeelde op die bord doen waarna die leerders ’n hele aantal soortgelyke roetine-oefeninge doen.

Ek voer aan dat nadsat as doelgemaakte taal tot ’n toestand van leserbetrokkenheid lei, wat deur middel van ’n motiveringstruktuur van lees-vir-plesier ‘vloei’ in die leesproses bewerkstellig. Lesernuuskierigheid versterk die gevoel van vervulling wat die bemeestering van nadsat meebring, positief. Leserafkeer vind plaas met die verstaan vannadsat. Afkeer word veroorsaak deur die wreedaardigheid wat deur die nadsat-narratief gekommunikeer word. Hierdie afkeer veroorsaak egter nie dat die leser ophou met lees nie, maar dien as sensasiebeluste motivering om aan te hou met lees. Hierdie soort motivering word as negatiewe versterking beskou. Beide motiveringstrukture (positiewe en negatiewe versterkers veroorsaak die ossilasie tussen leserbetrokkenheid en -afkeer as deel van die leeservaring wat A clockwork orange bied. Die doel van hierdie artikel is om die ossilasie tussen leserbetrokkenheid en -afkeer te verduidelik volgens die teoretiese raamwerke wat hierbo aangedui is.

    Full Text Available The play of association in and around 'The liberation of the image' by Breyten Breytenbach This analysis focuses on the conjunction of memory and imagination, which is an important impulse in, and key to, Breytenbach’s work. The play with language and with associations, the foregrounding, in the short story, “Die verlossing van die beeld” (Breytenbach, 1983 with its metafictional title and apparently divergent motifs (rain/water, watch, onion, the death and burial of a grandfather acts, as it were, as an invitation to the reader to become a co-player. The reader ventures on a search for traces, intertextual links within the Breytenbach oeuvre and for already acknowledged influences such as Surrealism (which in turn casts some light on the strange title of the story and the Eastern philosophies such as Zen and the even older Taoism. The analysis also takes into account the context in which “Mouroir” was written, namely Breytenbach’s term in prison (1975-1982. Seeing that the writer had to hand in his manuscripts to the jail authorities regularly, he might have decided, consciously or by intuition, to hide some thoughts and feelings behind a screen or a mask, in, for example in “Die verlossing van die beeld”, a lighter tone and irony.

  12. The thermal fatigue resistance of H-13 Die Steel for aluminum die casting dies

    Science.gov (United States)

    1982-01-01

    The effects of welding, five selected surface coatings, and stress relieving on the thermal fatigue resistance of H-13 Die Steel for aluminum die casting dies were studied using eleven thermal fatigue specimens. Stress relieving was conducted after each 5,000 cycle interval at 1050 F for three hours. Four thermal fatigue specimens were welded with H-13 or maraging steel welding rods at ambient and elevated temperatures and subsequently, subjected to different post-weld heat treatments. Crack patterns were examined at 5,000, 10,000, and 15,000 cycles. The thermal fatigue resistance is expressed by two crack parameters which are the average maximum crack and the average cracked area. The results indicate that a significant improvement in thermal fatigue resistance over the control was obtained from the stress-relieving treatment. Small improvements were obtained from the H-13 welded specimens and from a salt bath nitrogen and carbon-surface treatment. The other surface treatments and welded specimens either did not affect or had a detrimental influence on the thermal fatigue properties of the H-13 die steel.

    Abstract

    The impact of tutorials on achievement in mathematics of first year students

    Historically disadvantaged students in South Africa often underachieve in mathematics due to a number of factors. Action research that was conducted at the (former Technikon Northern Gauteng to investigate ways in which these students’ achievements in mathematics could be improved comprised the implementation of tutorial sessions. Quantitative and qualitative data were gathered by means of a variety of instruments. The results revealed certain trends in tertiary mathematics education where learning takes place in a second or third language.

    Full Text Available Der Beitrag untersucht, inwiefern sich medienpädagogisch relevante Diskrepanzen zwischen dem Diskurs der Wissensgesellschaft und jugendlichem Medienhandeln nachzeichnen lassen. Dazu werden zunächst einige Aspekte des Konstrukts Wissensgesellschaft skizziert, das in seiner gegenwärtig populären Form ins Fahrwasser an volkswirtschaftlichen Verwertungskalkülen orientierter Denkformen geraten ist. Dies wird in Bezug auf die sich daran gekoppelte Programmatik von Kompetenz diskutiert, welche den «homo oeconomicus» beschwört und sich darin konträr zu klassisch bildungstheoretischen Kategorien verhält. Weitergeführt werden diese Überlegungen anhand der Problematisierung des Medienkompetenztheorems, das sich bis heute damit schwer tut, sich von der Vereinnahmung durch zweckrationale und restringierende Tendenzen zu befreien. Argumentiert wird, dass mit Medienkompetenz zu wenig einer milieuspezifischen Differenzierung Rechnung getragen werden kann, die eine wichtige Prämisse für eine soziale Ungleichheiten ernst nehmende Medienpädagogik ist. Als eine Alternative diskutieren wir, inwieweit sich hier praxeologische Perspektiven zum Verständnis jugendlichen Handelns anbieten. Der Beitrag mündet in einige medienpädagogisch fruchtbare Ideen, in deren Zentrum eine reflexivere, stärker am Habitus von Jugendlichen orientierte Praxis steht.

    Even shortly after World War II, as large amounts of ultrapure rare earths (RE) became available for scientific research, a large reservoir of peculiar phenomena was uncovered. These had not been investigated before or were completely unknown. Examples of these phenomena are, magnetic ordering, the KONDO effect, quantum critical points, heavy fermion behaviour, as well as superconductivity. A strong influence of small variations of the chemical composition on the physical properties had been observed. The main focus of the present thesis is the detailed elucidation of the crystal structure of fundamental representatives of this class of substances, as well as the influence of dedicated variations of the chemical composition on their structure and properties. In particular, the characterisation of modulated crystals is an important facet. A large spectrum of physical methods, especially X-ray diffraction, is employed in the investigations. Results on oriented intergrowth in the Y-Ni-B-C system, incommensurately ordered vacancies in the Ce-Si system, incorporation of stacking faults as well as commensurately ordered transition metal atoms (TM) in the RE-TM-Si system and site specific occupancy in the Y-Mn-Fe-O system are presented. Their elucidation is reported for the first time. It is shown which consequences the structural peculiarities will have on the physical properties. An objective of this thesis is to give an overview of the possible ''answers'' that can be obtained with regard to the influence of the crystal structure of rare earth transition metal compounds on deviations of the chemical composition.

    Full Text Available Na 30 jaar kon die grammaties-historiese metode van Skrifondersoek nie daarin slaag om die etiese probleem van die vrou in die kerklike ampte (en homoseksualiteit in die GKSA op te los nie. Hierdie metode kan na alle waarskynlikheid nie meer as die enigste verklaringsmetode gebruik word nie en moet deur ander uitgangspunte aangevul word. In hierdie artikel word twee hermeneutiese uitgangspunte bespreek wat saam met die grammaties-historiese metode in die vertolking van die Skrif gebruik kan word. Hierdie hermeneutiese uitgangspunte sal gedemonstreer word in ‘n bespreking oor die etiese verstaan van die vrou in die Bybel, spesifiek soos dit op die vrou in kerklike ampte toegepas word. In aansluiting by laasgenoemde twee vertrekpunte word in ’n opvolgartikel ’n verdere drie hermeneutiese vertrekpunte behandel. Die twee hermeneutiese vertrekpunte wat in hierdie artikel behandel word, staan as reëldoelwit en analogie bekend. Die eerste hermeneutiese vertrekpunt gaan uit van die veronderstelling dat die reëldoelwit van ’n teks swaarder weeg as die teks self, terwyl analogie van die veronderstelling uitgaan dat analogie as beredenering ’n aanvaarbare en noodsaaklike vertrekpunt is. Bogenoemde hermeneutiese vertrekpunte (vyf in totaal is op twee aannames gegrond. Ten eerste word aanvaar dat die Bybel, alhoewel ’n goddelike boek, ’n besliste kreatuurlike kant het wat in die vertolking daarvan in ag geneem moet word. Tweedens word geredeneer dat die Skrif nie ’n  teologiese boek is nie, wat beteken dat gelowiges in etiese sake waaroor daar twee verstaansmoontlikhede bestaan, die reg gegun moet word om self die Skrif te vertolk. Daar word tot die  gevolgtrekking gekom dat ’n etiese verstaan van die vrou daartoe moet lei dat die vrou as gelykwaardig aan die man beskou en behandel moet word, met die gevolg dat die vrou tot alle ampte in die kerk toegelaat moet word.

  20. Killing, letting die and euthanasia.

    Science.gov (United States)

    Husak, D N

    1979-12-01

    Medical ethicists debate whether or not the moral assessment of cases of euthanasia should depend on whether the patient is 'killed' or 'allowed to die'. The usual presupposition is that a clear distinction between killing and letting die can be drawn so that this substantive question is not begged. I contend that the categorisation of cases of instances of killing rather than as instances of letting die depends in part on a prior moral assessment of the case. Hence is it trivially rather than substantively true that the distinction has moral significance. But even if a morally neutral (ie non-question begging) distinction could be drawn, its application to the euthanasia controversy is problematic. I illustrate the difficulties of employing this distinction to reach moral conclusions by critically discussing Philippa Foot's recent treatment of euthanasia. I conclude that even if an act of euthanasia is an instance of killing, and there exists a prima facie moral duty not to kill, and no more stringent duty overrides this duty, one still cannot determine such an act to be morally impermissible.

    Do we need the fire brigade in a power plant? This question is to be answered in the affirmative. The fire brigade, in addition, is of greater use than it costs. Decisive for the formation and structure of a fire brigade are the hazard potential of the respective plant and its organisational structure. The bases must be defined in close cooperation between operator and approving authority. The striking force of the works internal fire protection depends on the incorporation of the fire brigade into the power plant organisation. Provided the synthesis is optimal - consisting of preventive fire protection, defensive fire protection, technical aid and possible rescue service - the fire brigade will make a decisive contribution to the long-term operating results of a power plant. (orig.) [German] Brauchen wir im Kraftwerk eine Feuerwehr? Diese Frage ist mit 'Ja' zu beantworten - und die Feuerwehr leistet darueber hinaus mehr, als sie kostet. Ausschlaggebend fuer den Aufbau und die Struktur der Feuerwehr ist das Gefaehrdungspotential des jeweiligen Betriebes und dessen Organisationsstruktur. Die Ausgangspunkte muessen in enger Abstimmung zwischen Betreiber und Genehmigungsbehoerde definiert werden. Entscheidend fuer die Schlagkraft des betrieblichen Brandschutzes ist eine entsprechende Einbindung der Organisationseinheit Feuerwehr in die Kraftwerksorganisation.

Hierdie studie het ten doel om te bepaal of daar ’n verskil is in die uitbeelding van die vrou in die Huisgenoot uitgawes van onderskeidelik 1963 en 2013. Volgens navorsing werk die visuele beeld en geskrewe teks saam om ’n boodskap oor te dra. Multimodale diskoersanalise (MDA word juis gebruik om beide visuele beeld en geskrewe teks te bestudeer. Sodoende word die metode van intersemiotiese komplementariteit binne MDA in hierdie studie gebruik.

    Full Text Available Die verkryging van akkurate, betroubare inligting aangaande die gehoorvermoë van jong kinders is van besondere belang vir die oudioloog, maar word dikwels bemoeilik aangesien die kleuter nie goeie samewerking bied in die vreemde pedo-oudiometriese situasie nie. Die oplossing hiervoor is grootliks geleë in die opleiding van die kind voor formele  gehoortoetsing en meer spesifiek  opleiding tuis deur die ouer. Die doel van hierdie studie was om 'n voorbereidende program op te stel wat die ouer tuis met die kind kan uitvoer, voordat formele  toetsing plaasvind. Die waarde en effek van hierdie program in die pedo-oudiometriese situasie is geevalueer by 'n groep drie- en vierjarige kleuters. Resultate dui daarop dat laer en meer akkurate drempels, 'n korter toetstydperk, verminderde angs en beter samewerking verkry is by die kleuters wat vooraf  opleiding ontvang het. Die opleidingsprogram kan dus in die kliniese praktyk benut word as voorafopleiding  vir pedo-oudiometrie.
