Dirac Spinors and Flavor Oscillations

In the standard treatment of particle oscillations the mass eigenstates are implicitly assumed to be scalars and, consequently, the spinorial form of neutrino wave functions is not included in the calculations. To analyze this additional effect, we discuss the oscillation probability formula obtained by using the Dirac equation as evolution equation for the neutrino mass eigenstates. The initial localization of the spinor state also implies an interference between positive and negative energy components of mass eigenstate wave packets which modifies the standard oscillation probability.Comment: 14 pages, 1 figure, AMS-Te

Reconclining phi radiative decays with other data for a0(980), fo(980), pi-pi -> KK and pi-pi -> eta-eta

Data for phi -> gamma (eta-pizero) are analysed using the KK loop model and compared with parameters of a0(980) derived from Crystal Barrel data. The eta-pi mass spectrum agrees closely and the absolute normalisation lies just within errors. However, BES parameters for fo(980) predict a normalisation for phi -> gamma (pizero-pizero) at least a factor 2 lower than is observed. This discrepancy may be eliminated by including constructive interference between fo(980) and sigma. The magnitude required for sigma -> KK is consistent with data on pi-pi -> KK. A dispersion relation analysis by Buttiker, Descotes-Genon and Moussallam of pi-pi -> KK leads to a similar conclusion. Data on pi-pi -> eta-eta also require decays of sigma to eta-eta. Four sets of pi-pi -> KK data all require a small but definite fo(1370) signal.Comment: 21 pages, 11 figures, Small rearrangement of reference

FORMATION OF A PENTAGONAL PARTICLE STRUCTURE FROM COPPER NANOCLUSTERS

The structure o f pentagonal particles and the processes o f their formation from nanoclusters with the fifthorder symmetry axes are investigated by the methods o f computer modeling and scanning electron-ion microscopy using copper as an example. It is demonstrated that the mechanism o f cluster growth to pentagonal particles can be realized at which the volumetric stress present in noncrystal clusters will be released without breaking o f the fifth-order symmetry o f the growing cluster shape

Reforming the Westminster Model of Agency Governance: Britain and Ireland after the Crisis

Conventional understandings of what the Westminster model implies anticipate reliance on a top-down, hierarchical approach to budgetary accountability, reinforced by a post-New Public Management emphasis on re-centralizing administrative capacity. This paper, based on a comparative analysis of the experiences of Britain and Ireland, argues that the Westminster model of bureaucratic control and oversight itself has been evolving, hastened in large part due to the global financial crisis. Governments have gained stronger controls over the structures and practices of agencies, but agencies are also key players in securing better governance outcomes. The implication is that the crisis has not seen a return to the archetypal command-and-control model, nor a wholly new implementation of negotiated European-type practices, but rather a new accountability balance between elements of the Westminster system itself that have not previously been well understood

SMALL FARMERS FROM RURAL AREAS ATTITUDE ON ORGANIC FOOD

This paper is one of the few marketing research done in rural areas of attitudes towards green products. Even if the subject is generally treated at the international level, Romania has an important specific is to be taken into account in the European area. Size of agricultural holdings and their degree of technology do not have the desired agricultural economic efficiency of modern economies. But by applying marketing techniques and by approaching customer needs, the agricultural sector in Romania can develop in another direction no longer going through the business model of major West European farmers. We are referring here to transition to a agriculture on small areas, intensively exploited and ecology and a system of distributed in the markets with a big search for such products. But he must know how people in rural areas see these green products and how they are trained to understand the concepts of green marketing and marketing organic products. These issues have been dealt with in the first part of the work. The second part of this paper aims to describe the attitude of small agricultural producers towards organic products and the degree in which they are willing to go to such a production. Research is based on a survey an explorer in two rural areas of Romania one at the mountain and the other in lowlands and shows the degree of adaptation for small producers to new market requirements. Results have been contradictory. Some of them have confirmed the assumptions, namely the opening to such a grown for, and others have shown a much greater degree of the use of chemical compounds in agriculture than expected. Also the degree of taking the initiative in rural areas was an issue that came out at a level lower than expected. This is a worrying conclusion but worth being taken into account. This research gives the image concept in rural areas being the starting point for further research and strategies which to propose turning Romania into a net exporter of organic production
