Efeziërs 1,7-10 in de nieuwe bijbelvertaling

De zogeheten lofzang van de brief aan de Efeziërs, 1,3-14, bestaat uitéén lange zin, de langste van het Nieuwe Testament, in een overdadigeen overladen stijl. God wordt er geprezen, omdat hij ons in en doorChristus met allerhande geestelijke zegeningen gezegend heeft (v. 3),ons uitverkozen heeft om een heilig leven te leiden en ons door JezusChristus voorbestemd heeft tot kindschap. Dit moet strekken tot lofvan zijn heerlijke genade, waarmee hij ons in de geliefde Christus begenadigd heeft (vv. 4-6). Door Jezus’ bloed hebben we de verlossingontvangen, de vergiffenis van onze zonden, en dit dank zij de rijkdomaan genade die God ons overvloedig in alle wijsheid heeft geschonken.Dit blijkt daaruit dat hij ons het geheim van zijn wil bekend gemaaktheeft om in Christus alles in hemel en op aarde onder één hoofd tebrengen (vv. 7-10). In Christus zijn wij, die als vroegere joden reedslang op hem hadden gewacht, erfgenamen geworden. Maar ook gij,christenen uit het heidendom, werdt verzegeld met de beloofde heiligeGeest, die het onderpand is van onze erfenis, dit alles tot verlossingvan zijn verworven bezit, tot lof van zijn heerlijkheid (vv. 11-14).In deze lofzang valt op dat Gods uitverkiezing in Christus plaatsheeft“voor de grondlegging van de wereld” (v. 4); dit geldt ook voorde voorbestemming (v. 5). God heeft dus met de preëxistente Christusvan alle eeuwigheid in de hemel gepland en beslist wat op aarde in de tijd geschied is en nog zal geschieden. In 1,3-14 volgen drie lange bijzinnen op elkaar, de verzen 7-10, 11-12 en 13-14, elk beginnend met ejn w|/ (“in wie”). Dit betrekkelijk voornaamwoord heeft ook iedere keer “Christus” als antecedent, in vers 6 in de vorm van “de geliefde”. Deze korte bijdrage beperkt zich

Lateral Casimir force beyond the Proximity Force Approximation

We argue that the appropriate variable to study a non trivial geometry dependence of the Casimir force is the lateral component of the Casimir force, which we evaluate between two corrugated metallic plates outside the validity of the Proximity Force Approximation (PFA). The metallic plates are described by the plasma model, with arbitrary values for the plasma wavelength, the plate separation and the corrugation period, the corrugation amplitude remaining the smallest length scale. Our analysis shows that in realistic experimental situations the Proximity Force Approximation overestimates the force by up to 30%.Comment: 4 pages.

Examining Expectations: Inspecting the Experiences of Student Teaching Interns in a Yearlong Paired-Placement at an Urban School

This paper examines the experiences of student teaching interns in paired-placements in an urban school setting, specifically how the pairs experience collaboration between themselves, mentor teachers, and university field instructors. In addition, the paper will examine how the paired teaching interns are able to perceive instruction that the students received. Using data from two participant surveys collected from student-teaching interns in paired-placements, results were compared with studies from academic literature and my own experience as a paired teaching intern. A thematic analysis was carried out with the data, in which was found evidence that the teaching interns enjoyed the extra support a partner provided and that students in the classroom appeared to have benefited from the additional resource. The data provided additional evidence that there was a lack of clarity between interns, mentor teachers, and university field instructors. The paper will propose strategies that will work to avoid these issues in future implementations

Radiative heat transfer between two dielectric nanogratings in the scattering approach

We present a theoretical study of radiative heat transfer between dielectric nanogratings in the scattering approach. As a comparision with these exact results, we also evaluate the domain of validity of Derjaguin's Proximity Approximation (PA). We consider a system of two corrugated silica plates with various grating geometries, separation distances, and lateral displacement of the plates with respect to one another. Numerical computations show that while the PA is a good approximation for aligned gratings, it cannot be used when the gratings are laterally displaced. We illustrate this by a thermal modulator device for nanosystems based on such a displacement

Thermal Casimir force between nanostructured surfaces

We present detailed calculations for the Casimir force between a plane and a nanostructured surface at finite temperature in the framework of the scattering theory. We then study numerically the effect of finite temperature as a function of the grating parameters and the separation distance. We also infer non-trivial geometrical effects on the Casimir interaction via a comparison with the proximity force approximation. Finally, we compare our calculations with data from experiments performed with nanostructured surfaces

Band structure analysis of the conduction-band mass anisotropy in 6H and 4H SiC

The band structures of 6H and 4H SiC calculated by means of the FP-LMTO method are used to determine the effective mass tensors for their conduction-band minima. The results are shown to be consistent with recent optically detected cyclotron resonance measurements and predict an unusual band filling dependence for 6H-SiC.Comment: 5 pages including 4 postscript figures incorporated with epsfig figs. available as part 2: sicfig.uu self-extracting file to appear in Phys.

Defining user perception of distributed multimedia quality

This article presents the results of a study that explored the human side of the multimedia experience. We propose a model that assesses quality variation from three distinct levels: the network, the media and the content levels; and from two views: the technical and the user perspective. By facilitating parameter variation at each of the quality levels and from each of the perspectives, we were able to examine their impact on user quality perception. Results show that a significant reduction in frame rate does not proportionally reduce the user's understanding of the presentation independent of technical parameters, that multimedia content type significantly impacts user information assimilation, user level of enjoyment, and user perception of quality, and that the device display type impacts user information assimilation and user perception of quality. Finally, to ensure the transfer of information, low-level abstraction (network-level) parameters, such as delay and jitter, should be adapted; to maintain the user's level of enjoyment, high-level abstraction quality parameters (content-level), such as the appropriate use of display screens, should be adapted

Vacuum induced torque between corrugated metallic plates

We study the torque arising between two corrugated metallic plates due to the interaction with electromagnetic vacuum. This Casimir torque can be measured with torsion pendulum techniques for separation distances as large as 1$\mu$m. It allows one to probe the nontrivial geometry dependence of the Casimir energy in a configuration which can be evaluated theoretically with accuracy. In the optimal experimental configuration, the commonly used proximity force approximation turns out to overestimate the torque by a factor 2 or larger.Comment: 7 pages, 4 figures, to appear in Europhysics Letters.
