Teachers' narratives of pedagogical practices: To educate for democratic peace in Egypt and in Canada

Education for democratic peacebuilding citizenship includes four essential components: handling conflict, practising dialogue, recognizing diversity, and building a pedagogical community. Teachers can help one another to interpret, to learn, and to implement these pedagogical practice dimensions, in order to equip their students with democratic agency and values to participate in peacebuilding social change. This comparative case study research examines how two groups of private school teachers ‒ four in the Greater Cairo area and three in the Greater Toronto area ‒voluntarily embarked on two journeys of non-formal professional learning to improve their teaching for democratic peace. The researcher developed and facilitated a six-session collaborative, reflective dialogic professional learning course for democratic peacebuilding, and studied each group of teachers’ pedagogical practices

Improved Fermentation Process for Producing Methane from Cheese Whey

Two methods of single-stage fermentation were used to produce methane from whey. The first method involved batch fermentation in which the pH was automatically controlled at 7.0. In addition to pH control, the second method was characterized by introducing the substrate continuously into the fermenter along with dilution water to keep the organic acids at a non-toxic level. The first method did not improve the production of methane compared to the batch fermentation in which a pH control system was not used (41). However, the second method showed that the concentration of organic acids has a major effect on limiting the production of methane from whey, and that by diluting the substrate with water the concentration of these acids was kept at levels not toxic to methanogenic bacteria until the population of methanogenic bacteria was such that they could convert organic acids to methane as rapidly as the acids were produced by non-methanogenic bacteria in a continuous process. This continuous process was capable of producing .179 m3 methane per kilogram of lactose in cheese whey

Broadband probing magnetization dynamics of the coupled vortex state permalloy layers in nanopillars

Broadband magnetization response of coupled vortex state magnetic dots in layered nanopillars was explored as a function of in-plane magnetic field and interlayer separation. For dipolarly coupled circular Py(25 nm)/Cu(20 nm)/Py(25 nm) nanopillars of 600 nm diameter, a small in-plane field splits the eigenfrequencies of azimuthal spin wave modes inducing an abrupt transition between in-phase and out-of-phase kinds of the low-lying coupled spin wave modes. The critical field for this splitting is determined by antiparallel chiralities of the vortices in the layers. Qualitatively similar (although more gradual) changes occur also in the exchange coupled Py(25 nm)/Cu(1 nm)/Py(25 nm) tri-layer nanopillars. These findings are in qualitative agreement with micromagnetic dynamic simulations

Thermal energy storage enhancement of a binary molten salt via in-situ produced nanoparticles

Thermal energy storage (TES) system is an essential component of any concentrating solar thermal power (CSP) plant to ensure a reliable plant operation even at night or cloudy weather. To enhance the TES capacity, a one-step method was proposed to synthesize nano-salts by in-situ production of CuO nanoparticles, via a high temperature decomposition of copper oxalate, in a binary salt used as a phase change material (PCM). The specific heat of the nano-salt both for solid and liquid phases were measured by differential scanning calorimetry (DSC) with the weight fraction of CuO nanoparticles varied from 0.1 to 3.0 wt%. The maximum specific heat increment of 7.96% in solid phase and 11.48% in liquid phase, were achieved at a CuO nanoparticle concentration of 0.5 wt%. A forming of intermediate layers composing of needle-like structures between nanoparticles and the salt was observed. The mixing model considering such an intermediate layer can be used to explain the observed specific heat enhancement at low particle concentrations. Both latent heat and onset temperature were decreased with increasing concentrations of CuO nanoparticles, while the melting temperature range was increased. When considering both latent heat and sensible heat contributions, the maximum increment of TES was achieved as 4.71% at 0.5 wt% CuO concentration in the temperature range from 160 °C to 300 °C

The Impact of Information Systems Management Elements on Human Resource Development: The Case of Jordan Commercial Bank

We investigate the impact of information systems management on human resource development at the Jordan Commercial Bank (JCB). The study’s sample consists of (192) employers, division chief, and manager who work in the JCB and its branches spread all over Jordan. To achieve the goals of this study a questionnaire is designed to estimate the impact of applying information systems management (building an infrastructure and improving strategic planning) on human resource development in the Jordan Commercial Bank by measuring professional growth, staff performance, and staff satisfaction as a human resource development domains. It is shown that: i) the range of information system management at the JCB has a significant positive effect in terms of organizational performance and strategic planning “from the organizational perspective”, likewise, the professional growth, job satisfaction and performance of the employees “from the personal perspective”, ii) the range of human resource development at JCB is medium, iii) there is a significant statistical effect of information system management on human resource development at JCB, iv) there is a significant statistical effect on the elements of information system management (professional development, staff performance, and staff satisfaction), v) there are no effects of (gender, employment position, and experience) on both information system management and human resource development. The research recommends that (JCB) management should concentrate on the staff satisfaction domain by giving promotions and some privileges and (JCB) management should exchange experiences with local and international banks

UTJECAJ BUBRENJA NA SMIČNU ČVRSTOĆU KONTAKTNE POVRŠINE ŠEJLA I VAPNENCA

Rock slope stability is almost controlled by the behaviour of the interface between rock layers. The presence of shale layers between limestone layers complicates this behaviour. As the shale layer undergoes swelling with moisture, it causes the shear interface properties to change with a specific behaviour different from the dry state. The behaviour will depend on the shale’s degree of saturation, swelling percentage, and stress level over shale. An experimental program was carried out to determine the shear interface behaviour parameters of shale-limestone during swelling phenomena to guide stability checks. The interface cohesion and friction angle results are reported along the swelling process and compared with the dry state condition. These results help engineers assign adequate and accurate values for joint shear and normal stiffness in jointed rock slopes, including swelling layers.Stabilnost stijenskih kosina uglavnom je uvjetovana interakcijom kontaktne površine između slojeva stijenske mase. Prisutnost slojeva šejla između slojeva vapnenca usložnjava tu situaciju. Kako sloj šejla bubri zbog vlage, dolazi do promjene svojstava kontaktne površine koja se specifično razlikuje od suhoga stanja. Ponašanje će ovisiti o stupnju zasićenosti šejla, postotku bubrenja i veličini naprezanja u materijalu iznad šejla. Provedeno je eksperimentalno ispitivanje za određivanje parametara ponašanja smicanja kontaktne površine šejla i vapnenca tijekom pojave bubrenja te je provedena provjera stabilnosti. Vrijednosti kohezije i kuta unutarnjega trenja na kontaktnim površinama opažane su tijekom procesa bubrenja i uspoređivane su s vrijednostima suhoga stanja. Ti rezultati pomažu inženjerima odabrati odgovarajuće i pouzdane vrijednosti smične i normalne krutosti za diskontinuirane stijenske kosine na kojima se pojavljuju slojevi koji bubre

Tension term, interchange symmetry, and the analogy of energy and tension laws of the AdS soliton solution

In this paper, we reconsider the energy and tension laws of the Ricci flat black hole by taking the contribution of the tension term into account. After this considering and inspired by the interchange symmetry between the Ricci flat black hole and the AdS soliton solution which arises from the double analytic continuation of the time and compact spatial direction, we find out the analogy of the energy and tension laws of the AdS soliton solution. Moreover, we also investigate the energy and tension laws of the boosted Ricci flat black hole, and discuss the boosted AdS soliton solution. However, although there is the same interchange symmetry between the boosted Ricci flat black hole and boosted AdS soliton, the analogy of laws of the boosted AdS soliton solution may be of no sense for the existence of the closed timelike curves and conical singularity. In spite of that, the conserved charges such as the energy and momentum of the boosted AdS soliton are well-defined, and an interesting result is that its energy is lower than that of the static AdS soliton. On the other hand, note that although the laws obtained above are the same as those of the asymptotically flat case, the underlying deduced contents are different. Thus, our results could also be considered as a simple generalization to the asymptotically AdS case. Moreover, during the calculation, we find that there may be a new way to define the gravitational tension which can come from the quasi-local stress tensor of the counter-term method.Comment: V4: 15 pages, no figure, version to appear in JHE
