[en] This paper is about one of the most fascinating competitions between university students: the International Physicists’ Tournament (IPT). The IPT is a team competition. The most interesting and challenging problems for the IPT are selected by vote long before the contest. The competition is meant to be close to real scientific life: the solution of the problem is presented, and then opposed and reviewed; the solution usually contains self-made and profound theoretical and experimental investigations. The tournament promotes science among the students and helps them establish international scientific relations. (paper)
[en] It is argued that in order to compete in an outcome-based climate, the radiation oncology practice have to make a strong argument that it is not only effective but that is also cost-effective. The four steps in the evaluation of the health interventions are outlined. They include: (1) efficacy; does it work in a controlled clinical experiment such as clinical trial?, (2) efficiency; does it works in the real world?, (3) Cost efficiency: how much it cost? and (4) marginal cost efficiency; how much does the extra benefit above standard treatment cost? 6 refs
[en] An overview of the online competition, Physics Cup—IPhO2012 is given. This preceded the 43rd International Physics Olympiad and included ten problems, published monthly. Three problems, the most popular among the contestants, are discussed in detail. These problems deal with laser speckle patterns, geometrical optics and LC circuits with four degrees of freedom. The results of the competition and of the poll carried out among the contestants are used to discuss the relationship between the properties of the problems: difficulty, closeness to reality and beauty (as perceived by the contestants).

[en] We report on the competition problems given at the 39th International Physics Olympiad held in Hanoi, Vietnam, which consist of three theoretical and one experimental problems. The abbreviated solutions are presented. The distribution of marks for the problems is also shown.
[en] Interconnections can be an effective way to increase competition and improve market integration in concentrated wholesale electricity markets with limited number of participants. This paper examines the potential for interconnections and increasing market integration in the Irish Single Electricity Market (SEM). We use a time-varying Kalman filter technique to assess the degree of market integration between SEM and other large, mature and interconnected wholesale electricity markets in Europe including Great Britain (GB). The results indicate no market integration between SEM and other European markets except for Elspot and GB. We show that the current state of market integration between SEM and GB is just 17% indicating potential to improve market integration via increased interconnector capacity. The results indicate that liquidity of wholesale markets might be a crucial factor in the market integration process while our results remain inconclusive in determining whether increased trade of renewables can improve market integration. - Highlights: ► We assess the degree of market integration between SEM and other EU electricity markets. ► Our results indicate no market integration between SEM and other European markets except for Elspot and GB. ► We show that the current state of market integration between SEM and GB is just 17%.
[en] Taiwan’s traditional industries are subject to competition in the era of globalization and environmental change, the industry is facing economic pressure and shock, and now sustainable business can only continue to improve production efficiency and quality of technology, in order to stabilize the market, to obtain high occupancy. The use of process capability indices to monitor the quality of the ratchet wrench to find the key function of the dual-use ratchet wrench, the actual measurement data, The use of process capability Cpk index analysis, and draw Process Capability Analysis Chart model. Finally, this study explores the current situation of this case and proposes a lack of improvement and improvement methods to improve the overall quality and thereby enhance the overall industry.

[en] In 1990, approximately 7.7% of the retail revenues of public power systems flowed to state and local governments in the form of tax payments and contributions. The argument is presented that this fact contradicts the notion that retail rates of investor-owned utilities are higher than public systems because investor-owned utilities (IOU's) pay taxes and public systems do not. Many IOU's promote this motion in an attempt to explain why their retail rates are significantly higher. It is concluded that relative tax payments and contributions fail to explain public powers rate advantage over IOU's
[en] We elucidate dipolar magnetic interaction effects in spinor condensates at a low-background field. In particular, we show that arrays of ferromagnetic spinor Bose–Einstein condensates show a rich phase structure that is strongly influenced by the competition of shape anisotropy and higher-order magnetostatic contributions both depending on the condensate's form.

[en] The European project was a promise for the peoples of Europe to take up together the technological, economic and scientific challenges that each nation could not face alone. Alas, the beautiful dream of European cooperation repeating the successes of Ariane or Airbus has crashed against the Europeanist bureaucracy and the impotent ideology of the European Treaties, which it zealously applies
