Linking Emotion, Cognition, and Action within a Social Frame: Old Testament Perspectives on Preaching the Fear of the LORD
Modern accounts of the meaning of âfear of the LORDâ in the Hebrew Bible have tended to distance this important concept from the emotion of fear, offering alternative understandings as worship, obedience, or wisdom. This essay examines phrases such as âfear of the LORD,â âfear of God,â and âGod-fearer,â across four sets of texts in the Hebrew Bible: 1) narratives in Genesis and Exodus; 2) Deuteronomy and other Deuteronomistic literature; 3) wisdom literature; and 4) Psalms. I argue that fear of the LORD/God in the Hebrew Bible typically does connote an emotional fear response that has in view divine power over life and death. The links between such fear and worship, and obedience, and wisdom that are attested in numerous biblical texts are not evidence of synonymy but a recognition of the fundamental link between emotion, cognition, and action. Recent developments in the study of emotion illuminate their interrelationship and the ways in which fear of the LORD/God is also socially shaped and shaping
On the relevance of large scale pulsed-laser deposition: Evidence of structural heterogeneities in ZnO thin films
Pulsed-laser deposition is known as a well-suited method for growing thin films of oxide compounds presenting a wide range of functional properties. A limitation of this method for industrial process is the very anisotropic expansion dynamics of the plasma plume, which induces difficulties to grow on large scale films with homogeneous thickness and composition. The specific aspect of the crystalline or orientation uniformity has not been investigated, despite its important role on oxide films properties. In this work, the crystalline parameters and the texture of zinc oxide films are studied as a function of position with respect to the central axis of the plasma plume. We demonstrate the existence of large non-uniformities in the films. The stoichiometry, the lattice parameter, and the distribution of crystallites orientations drastically depend on the position with respect to the plume axis, i.e., on the oblique incidence of the ablated species. The origin of these non-uniformities, in particular, the unexpected tilted orientation of the ZnO c-axis may be attributed to the combined effects of the oblique incidence and of the ratio between oxygen and zinc fluxes reaching the surface of the growing film
Frequency shifts of photoassociative spectra of ultracold metastable Helium atoms : a new measurement of the s-wave scattering length
We observe light-induced frequency shifts in one-color photoassociative
spectra of magnetically trapped He atoms in the metastable
state. A pair of ultracold spin-polarized helium atoms is excited into
a molecular bound state in the purely long range potential connected to
the asymptote. The shift arises from the optical coupling of
the molecular excited bound state with the scattering states and the bound
states of two colliding atoms. We measure the frequency-shifts for
several ro-vibrational levels in the potential and find a linear
dependence on the photoassociation laser intensity. Comparison with a
theoretical analysis provides a good indication for the s-wave scattering
length of the quintet () potential, nm, which
is significantly lower than most previous results obtained by non-spectroscopic
methods.Comment: 7 pages, 4 figure
Potential and current distribution in strongly anisotropic Bi(2)Sr(2) CaCu(2)O(8) single crystals at current breakdown
Experiments on potential differences in the low-temperature vortex solid
phase of monocrystalline platelets of superconducting Bi(2)Sr(2)CaCu(2)O(8)
(BSCCO) subjected to currents driven either through an "ab" surface or from one
such surface to another show evidence of a resistive/nonresistive front moving
progressively out from the current contacts as the current increases. The depth
of the resistive region has been measured by a novel in-depth voltage probe
contact. The position of the front associated with an injection point appears
to depend only on the current magnitude and not on its withdrawal point. It is
argued that enhanced nonresistive superconducting anisotropy limits current
penetration to less than the London length and results in a flat rectangular
resistive region with simultaneous "ab" and "c" current breakdown which moves
progressively out from the injection point with increasing current.
Measurements in "ab" or "c" configurations are seen to give the same
information, involving both ab-plane and c-axis conduction properties.Comment: 9 pages, 13 figures, typo error corrected, last section was refine
Experimental Test of the High-Frequency Quantum Shot Noise Theory in a Quantum Point Contact
We report on direct measurements of the electronic shot noise of a quantum
point contact at frequencies nu in the range 4-8 GHz. The very small energy
scale used ensures energy independent transmissions of the few transmitted
electronic modes and their accurate knowledge. Both the thermal energy and the
quantum point contact drain-source voltage Vds are comparable to the photon
energy hnu leading to observation of the shot noise suppression when
. Our measurements provide the first complete test of the finite
frequency shot noise scattering theory without adjustable parameters.Comment: Version Published in Phys. Rev. Lett. (Phys. Rev. Lett. 99, 236803

NUMERICAL SIMULATION OF PHOTOCURRENT IN A SOLAR CELL BASED AMORPHOUS SILICON
We propose in this work, a method of simulation based on the resolution of the equations of continuities for homostructures of silicon-based solar, and used a method of calculation the photocurrent delivered by the silicon solar cell applying the equations of continuities and the currents by analogy to the phenomena of loads transport according to the model of an homojunction n-a-Si:H/p-a-Si:H. We used Matlab software to simulate and optimize the layers thicknesses to achieve the maximum photocurrent generated under AM1.5 solar spectrum. The optimization of donor layer thickness shows clearly that the best results are obtained with the finest structures. Â We worked out a numerical model based on the resolution of the equations of continuities who gave the results in good agreement with literature and which allowed, moreover a better control of the performances of the cells based on silicon, for their improvement

Atomic scale observation of phase separation and formation of silicon clusters in Hf higk-Îș silicates
International audienceHafnium silicate films were fabricated by RF reactive magnetron sputtering technique. Fine microstructural analyses of the films were performed by means of high-resolution transmission electron microscopy and atom probe tomography. A thermal treatment of as-grown homogeneous films leads to a phase separation process. The formation of SiO2 and HfO2 phases as well as pure Si one was revealed. This latter was found to be amorphous Si nanoclusters, distributed uniformly in the film volume. Their mean diameter and density were estimated to be about 2.8 nm and (2.960.4) 1017 Si-ncs/cm3, respectively. The mechanism of the decomposition process was proposed. The obtained results pave the way for future microelectronic and photonic applications of Hf-based high-j dielectrics with embedded Si nanocluster
The synthesis of TiO2 thin film by Chemical Bath Deposition (CBD) method
Titanium oxide (TiO2) ïŹlms have several advantages for applications in solar cells and very commonly used as a photo-catalyst for degradation of environmental pollutants. In this study, TiO2 films were synthesized using, a simple, less expensive, low temperature and convenient for large area deposition method, a chemical bath deposition (CBD) and their structural and optical properties were examined at various calcinations temperatures. The X-ray diffraction (XRD) technique shows the presence of the picks characteristic of anatase phase after annealing our films at 500°C, 600°C and rutile phase appears after heat treatment at 700°C. The surface morphology of the deposited ïŹlms was characterized by the FEG scanning electronic microscopy (FEGSEM) and atomic force microscopy (AFM). Energy dispersive X-ray spectroscopy (EDS) analysis was used to determine the chemical composition of the prepared films. The UV-Vis-NIR spectroscopy shows that the ïŹlm exhibits a transmission around 60%. The indirect band gap of the deposited ïŹlms was between 2.88 and 3.22 eV
Granular Activated Carbons from Agricultural By-products: Process Description and Estimated Cost of Production (Bulletin #881)
This bulletin is a follow-up, in part, of Bulletin #869, âGranular Activated Carbons from Agricultural By-products: Preparation, Properties and Application in Cane Sugar Refining.â An estimation of production costs for these by product-based carbons was considered prudent because of the potential interest from both bagasse and shell producers and activated carbon manufacturers based on the use of these carbons in various applications compared to commercial carbons.https://digitalcommons.lsu.edu/agcenter_bulletins/1034/thumbnail.jp
