Noncommutative QED and Anomalous Dipole Moments

We study QED on noncommutative spaces, NCQED. In particular we present the detailed calculation for the noncommutative electron-photon vertex and show that the Ward identity is satisfied. We discuss that in the noncommutative case moving electron will show {\it electric} dipole effects. In addition, we work out the electric and magnetic dipole moments up to one loop level. For the magnetic moment we show that noncommutative electron has an intrinsic (spin independent) magnetic moment.Comment: 27 pages, several .ps and .eps figures, v3:typos in some formula corrected, version appeared in JHE

LEVERAGING SOA IN BANKING SYSTEMS INTEGRATION

There is no doubt that the systems integration is one of the most important and complicated tasks in software filed especially for complex applications like banking systems. Complexity in integrating banking systems often comes from continues changes in both technical and business features provided by them to meet customer needs. Banking systems always come from different software vendors which mean using platforms and different design and architecture patterns, and this for sure adds extra complexity for integrating them. Serviceoriented architecture (SOA) is a promising method in software filed that aims to build or restructure software systems in a manner that makes their maintenance and integration easier. Agility is the most important goal that should be achieved when building and integrating banking systems. Simply, agility is needed to meet market needs quickly and efficiently and SOA is the way that could provide itSOA, SOI, P2P Integration, Web Services, and Legacy Code

Software Support for Team Engineering: Educational Case for IT Students

Every scientific project is a result of efforts of professionals from different working areas on the basis of their combined knowledge implementation. In the view of a team work significance for IT professionals, team work was proposed for one course from IT educational programme as the main active learning method. To engineer effective teams, SNA-methodology was implemented. The results of this implementation were discussed in the classes as an example of information technology and corresponding software tool usage for a real problem solution. A comparative analysis of two different tools was carried out, which has yielded in one more educational effect. This example of integrated learning which involve students both into professional and scientific activity was proved to be useful for educating real IT specialists

The role of web-based promotion on the development of a relationship marketing model to enable sustainable growth

AbstractIn recent years the web-based Relationship Marketing (RM) has been receiving a great attention from e-marketing perspective. The RM is evolved as a contemporary marketing initiative, which can be applied to all types of industries. Concurrently, because of the advancement of the Information Technology, web-based promotion and market offering are considered as dominating business development tool. From this context, five grown sporting cases have been analysed to realise how web-based promotion influences RM to develop a sustainable growth model, where the cases have been utilising the RM and web-based promotion lucratively to attain and retain the key stakeholders to sustain their growth. Following the initial literature review, the websites of the cases have been scrutinised thoroughly as data collection tool. Nineteen RM indicators are identified as different RM perspectives. The cases are positioning web-based promotions and offerings underlying these RM indicators as a combined promotional effort to enhance competitive advantage. From the case analysis, the concept of stakeholder causal scope is evolved as identical with this combined promotional effort, as well as proportionate with at least one of the four identified growth strategies. Finally, the RM centred ‘Sustainable Growth Model’ has been developed through the synthesis of the impact of the web-based RM indicator focused combined promotional effort of the cases on the associated stakeholder causal scopes and their relevancy with the growth strategies. Reinforcing the model is established significantly for marketers in various industries to enhance competitive advantage aiming to sustain organisational growth

Food composition and feeding ecology of the Red Fox Vulpes vulpes (Linnaeus, 1758) in Egypt

Food composition of the Red Fox Vulpes vulpes populations in different habitats in Egypt is investigated based on the analysis of stomach contents. The analysis of 70 stomach contents demonstrates that the food of Red Fox is highly diverse and includes rodents, birds, reptiles,fishes, insects and other arthropods, fruits and other vegetable material. Certain individuals seem to also feed on carrion. Diet composition shows seasonal and geographical variations that are apparently associated with changes in the availability of different food items. The results clearlyshow that the Red Fox is an opportunistic omnivore, capable of adapting to a great variety of dietary compositions

Évolution de la température de l’air et des précipitations dans la région côtière syrienne (gouvernorat de Lattaquié) de 1970 à 2016

This study aims to analyze the changes in the annual and seasonal averages of air temperature and precipitation over Lattakia Governorate during the period 1970-2016. Annual and seasonal trends for temperature and precipitation were calculated by using the non-parametric Mann-Kendall test. The mean differences between the two periods 1970-2000 and 2001-2016, were assessed at the annual and seasonal scales by using the non-parametric Mann-Whitney U test. Furthermore, the occurrence of extreme high/low values were analyzed at the annual scale by using the normal distribution curve. The study found that the annual temperature averages significantly (p<0.05) increased by 0.22 ˚C/decade and 0.17 ˚C/decade, respectively at Lattakia and Hiffeh stations during the period 1970-2016. Summer exhibited strong and significant (at level 0.01) increasing trends by 0.39 ˚C/decade at Lattakia, and by 0.34 ˚C/decade at Hiffeh. Total spring precipitation significantly decreased by -6.5 mm/decade at Lattakia and by -12.1 mm/decade at Hiffeh. Probability of the occurrence of the value 20.2 ˚C or more as an extreme value increased by 40.8% at Lattakia station during the period 2001-2016. Este estudio tiene como objetivo analizar los cambios en los promedios anuales y estacionales de la temperatura del aire y las precipitaciones en la gobernación de Lattakia durante 1970-2016. Las tendencias anuales y estacionales para la temperatura y la precipitación se calcularon utilizando la prueba no paramétrica de Mann-Kendall. Las diferencias de medias entre los dos períodos (1970-2000) / (2001-2016) se evaluaron en los niveles anuales y estacionales mediante el uso de la prueba no paramétrica de Mann-Whitney U. Además, la aparición de valores extremadamente altos / bajos se analizó a nivel anual mediante el uso de la curva de distribución normal. El estudio encontró que los promedios anuales de temperatura aumentaron significativamente (p <0.05) en 0.22 ˚C / década y 0.17 ˚C \ década, en las estaciones de Lattakia y Hiffeh, respectivamente, durante 1970-2016. El verano reveló tendencias fuertes y significativas al alza (a nivel 0.01) en sus promedios de temperatura en 0.39 ˚C / década en Lattakia, y en 0.34 ˚C / década en Hiffeh. El promedio de precipitaciones de primavera disminuyó significativamente en -6.5 mm / década en Lattakia y en -12.1 mm / década en Hiffeh. La probabilidad de la aparición del valor de 20.2 ˚C o más como valor extremo aumentó en la estación de Lattakia durante 2001-2016 en un 40.8%.L’objectif de cette étude est d’analyser les changements dans les moyennes annuelles et saisonnières de la température de l’air et des précipitations sur la région du gouvernorat de Lattaquié entre 1970 et 2016. Les tendances annuelles et saisonnières de la température ont été calculées à l’aide du test non-paramétrique de Mann-Kendall. Les différences moyennes entre les périodes 1970-2000 et 2001-2016 ont été évaluées par année et saison en utilisant le test non-paramétrique de Mann-Whitney U. En ce qui concerne l’occurence de valeurs extrêmement élevées/ basses, celle-ci a été analysée sur une base annuelle en utilisant la courbe de distribution normale. L’étude a révélé que les températures moyennes annuelles (p<0,05) ont augmenté significativement de 0,22 ˚C / décennie et de 0,17 ˚C / décennie, dans les cas respectifs des stations de Lattakia et de Haffah durant la période 1970-2016. L’été a laissé voir une tendance marquée à la hausse (au niveau de 0,01) de ses moyennes de température : 0,39 ˚C / décennie à Lattaquié et 0,34 ˚C / décennie à Hiffeh. La moyenne des précipitations printanières a diminué de manière significative, soit de -6,5 mm / décennie à Lattakia et de -12,1 mm / décennie à Hiffeh. La probabilité d’apparition de la valeur de 20,2 ˚C ou plus comme valeur extrême a augmenté de 40,8% pour la station de Lattaquié pendant la période 2001-2016
