An optical threshold function based on polarization rotation in a single semiconductor optical amplifier

Optical threshold functions are a basic building block for alloptical signal processing, and this paper investigates a threshold function design reliant on a single active element. An optical threshold function based on nonlinear polarization rotation in a single semiconductor optical amplifier is proposed. It functions due to an induced modification of the birefringence of a semiconductor optical amplifier caused by an externally injected optical control signal. It is shown that switching from both the TE to the TM mode and vice versa is possible. The measured results are supported by simulation results based on the SOA rate equations. ©2007 Optical Society of Americ

Precision Measurement of PArity Violation in Polarized Cold Neutron Capture on the Proton: the NPDGamma Experiment

The NPDGamma experiment at the Los Alamos Neutron Science Center (LANSCE) is dedicated to measure with high precision the parity violating asymmetry in the $\gamma$ emission after capture of spin polarized cold neutrons in para-hydrogen. The measurement will determine unambiguously the weak pion-nucleon-nucleon ($\pi NN$) coupling constant {\it f$^1_{\pi}$}Comment: Proceedings of the PANIC'05 Conference, Santa Fe, NM, USA, October 24-28, 2005, 3 pages, 2 figure

Die erediens as instrument in gemeentebou – toegespits op die Gereformeerde Kerke in Suid-Afrika

Worship service as instrument in congregation-building – focused on the Gereformeerde Kerke in Suid-Afrika In this article worship service as an instrument in congregationbuilding is investigated – basis-, meta- and practical-theoretically. Congregation-building is defined as the unique ministry by which the community of believers is led to become what they as believers have already become through Christ. Congregation-building is concerned with growth in three relationships, that is, the relationship between the believer and God, the relationship between the believer and his fellow believers and the relationship between the believer and the world. It is concluded that worship service implies a meeting of God and his covenant people. Worship service therefore has a strong element of mutual building up and witness. Having undertaken a limited empirical study, it was found that the above-mentioned basistheoretical perspectives have not been fully realized in the practice of the GKSA. Even though worship service is experienced as a meeting with God, the dialogical and corporate character of the service, as well as the mutual building up and the relationship with the world, is neglected. Practice-theoretical guidelines are given to rectify this situation by bringing practice closer to theory. The equipping of the believer as well as of the pastor is identified as major concerns. The establishment of a liturgical service group is thus encouraged. The final conclusion is that worship service has a cardinal role to play in congregation-building

Basisteoretiese beginsels vir atmosfeer in die erediens afgelei uit 1 Korintiërs 11:17-14:40

Basis-theoretical principles for atmosphere in worship services deduced from 1 Corinthians 11:17-14:40 This article emphasises the central position that the worship service occupies in the life of the believer, but more to the point: the believer as a whole. The atmosphere is therefore vital. This is researched by an exegetical study of 1 Corinthians 1-14. The atmosphere in the worship service should be such that the worshipper meets God with the necessary awe and respect. The service must also create an atmosphere of love, warmth, friendliness and joy. All attenders must be invited and feel welcomed at the service. The atmosphere must further en- courage and create room for everybody to participate and use their specific gifts. If the atmosphere in the worship service is adjusted to what it should (and can!) be, the worship service will come closer to its purpose and will become even more of a meeting of the whole person of the believer with the omnipotent God and with every aspect of the fellow believers and the world.http://dx.doi.org/10.4102/ids.v41i2.305http://www.inluceverbi.org.za/index.php/skriflig/article/viewFile/305/20

Die atmosfeer in die erediens deur die loop van die geskiedenis

The worship service occupies a central position in the life of the believer and therefore the atmosphere in the worship service is vital. The variations through history are studied in this article. The viewpoints of the first four centuries, the Middle Ages, Reformation, post-Reformation and twentieth century came under discussion. Lessons from history are stated. The atmosphere in the worship service should be such that the worshipper meets God with the necessary awe and respect. The service must also create an atmosphere of love, warmth, friendliness, and joy. All present must be invited and made welcome by the service. The atmosphere must further encourage and create room for everybody to participate and use their specific gifts. It can therefore change from service to service and within a single service. Important instruments in the atmosphere are the liturgical space, symbols, rituals, physical movement, gestures, music, song and the senses.http://dx.doi.org/10.4102/ve.v28i1.97http://www.ve.org.za/index.php/VE/article/viewFile/97/7
