Neutrino factory for both large and small theta(13)
No full textAn analysis of the neutrino oscillation physics capability of a low-energy neutrino factory is presented, including a first simulation of the detector efficiency and event energy threshold. The sensitivity of the physics reach to the presence of backgrounds is also studied. We consider a representative baseline of 1480 km, we use muons with 4.12 GeV energy and we exploit a very conservative estimate of the energy resolution of the detector. Our analysis suggests an impressive physics reach for this setup, which can eliminate degenerate solutions, for both large and small values of the mixing angle theta(13), and can determine leptonic CP violation and the neutrino mass hierarchy with extraordinary sensitivity
A Complete Magnetic Design and Improved Mechanical Project for the DUNE ND-GAr Solenoid Magnet
No full textThe Deep Underground Neutrino Experiment (DUNE) at Fermilab is one the most challenging next-generation experiments in the field of neutrino physics. It will feature two detectors for a detailed study of neutrino oscillations using an unprecedentedly intense neutrino beam. The two detectors are a Near Detector located on the Fermilab site, 574m away from the neutrino generation, and a Far Detector in South Dakota, 1300km away. Among the three elements of the Near Detector, designed for the best understanding of the neutrino beam and neutrino interactions on argon, ND-GAr is a High-Pressure gaseous Argon TPC surrounded by a calorimeter, in a 0.5T magnetic field. The needed magnetic field is transverse to the neutrino beam direction and the solenoid will have a 7 m diameter, 8 m long warm bore. To minimise the material budget along the particle path a thin superconducting solenoid with a partial yoke has been designed. The design of this magnet is tightly bound with the mechanics of the detector, resulting in an unprecedented design. In this paper we present the up-to-date magnetic design and a detailed study for the mechanical integration for this magnet
The battered child syndrome : changes in the law and child advocacy
No full textIn 1962, Dr C. Henry Kempe and his colleagues published the single most important article written to date about child maltreatment: The Battered-Child Syndrome. This chapter analyses the threefold nature of what these authors achieved: clearly identifing the medical evidence of severe child physical abuse and naming it as a syndrome; identifying the medical profession's resistance to its identification; and then translating their scholarship into advocacy for social and legal change. The chapter also traces some of the effects of Kempe's work, including the nature and effect of the subsequent introduction of mandatory reporting laws in the USA and internationally
A Solenoid with Partial Yoke for the Dune near Detector
No full textThe Deep Underground Neutrino Experiment (DUNE) at Fermilab is one the most challenging next-generation experiments in the field of neutrino physics. It will feature two detectors for a detailed study of neutrino oscillations using an unprecedentedly intense neutrino beam. The two detectors are a Near Detector located on the Fermilab site, 574 m away from the neutrino generation, and a Far Detector in South Dakota, 1300 km away. The Near Detector consists of three subdetectors, based on different technologies in order to achieve the best understanding of the neutrino beam. One key element of the Near Detector is a High Pressure Argon TPC surrounded by a calorimeter. This detector will need a 0.5 Tesla magnetic field transverse to the neutrino beam direction, with a 7 m diameter, 8 m long warm bore. A thin superconducting solenoid with a partial yoke, needed in order to minimise the amount of material along the path particles take crossing the different elements of the Near Detector is proposed. In this paper we present a detailed magnetic analysis and a preliminary study of the cooling, the cable and the mechanics for this magnet

SUPPLIER SELECTION PROCESS IN EMERGING MARKETS -The Case Study of Volvo Bus Corporation in China-
No full text“Hearing a hundred times is not as good as seeing once” – Old Chinese Proverb The complexity of managing an international operating environment has changed significantly over the last few years. The increasing presence of Multinational Corporations in emerging markets has not only increased the advantages of developing global economies of scale, but it has also identified a need for the further coordination and assimilation of company activities into the local market of operation. As more and more MNCs begin entering the Chinese market in an effort to establish long-term competitive advantages and low cost production sites, there becomes an even greater need for a developed business infrastructure, globally integrated technology processes, greater overall efficiency, increased coordination of procedures and synchronized learning efforts. The aim of this thesis is to further investigate how MNCs transfer and apply their global supplier selection processes to emerging markets. We will use Volvo Bus Corporation as our case company, and we will focus our study on the transfer and application of their global supplier selection process to the Chinese market through their joint venture company, Silver Bus Corporation, in China. In order to present a realistic picture of how the supplier selection process is being carried out in the Chinese market, it is first necessary to present a broad overview of the Chinese bus industry and a description of the Chinese Automotive Industry Policy, as well as to provide a brief discussion of the environment in which our research was collected, for a more comprehensive understanding of the situational factors which were present at the time our research was conducted
Using law to identify, manage and prevent child maltreatment
No full textThis chapter identifies ways in which laws are capable of responding to child maltreatment, both as an immediate regulator of conduct, and as an influence on a society’s cultural development and approach to children’s welfare. Informed by practices and experiences in selected common law\ud
systems, the chapter provides examples of legal mechanisms that can inform discussion of optimal strategies to identify and manage child maltreatment in many different societies. Both positive and negative aspects of these mechanisms are noted. While controversies arise as to what kinds of laws are best in preventing and responding to child\ud
maltreatment, and even, more fundamentally, whether there is a role for law in protecting children, this chapter offers evidence that a variety of legal tools can be employed to address child abuse and neglect, for any\ud
cultural setting in which there is willingness to act to prevent and treat its various forms

The US Muon Accelerator Program (MAP)
No full textThe US Department of Energy Office of High Energy Physics has recently approved a Muon Accelerator Program (MAP). The primary goal of this effort is to deliver a Design Feasibility Study for a Muon Collider after a 7 year R&D program. This paper presents a brief physics motivation for, and the description of, a Muon Collider facility and then gives an overview of the program. I will then describe in some detail the primary components of the effort
RMAPW-Verfahren und selbstkonsistente Bandstruktur von Gold
No full textThe "Relativistic Modified Augmented Plane Wave" (RMAPW) method of Bross and Hofmann (1969) was realized numerically in a slightly modified form and tested with the example of copper potential of Burdick (1963). With regard to future applications in the area of surface-bandstructures and surface-states this realization was done in a generalization of the RMAPW-method for complex k-vectors ("complex RMAPW") of Wachutka (1978).
Starting from the "Overlapping Charge Density" (OCD) potential of gold in "Muffin Tin" (MT) form from Christensen and Seraphin (1971) in this work a selfconsistent gold potential in "Warped Muffin Tin" (WMT) form was computed. As a modell for the electron-electron interaction the effective local single-particle-potential in the context of the "Local Density Approximation" (LDA) with relativistic adjustments for the exchange-term of MacDonald and Vosko (1979) was used.
On the basis of the energy spectrum, the density of states, and the anisotropy of the fermi-surface the approximations of WMT and DFF/LDA are discussed. The most essential result is, that with the selfconsistent potential there is in the energy-scale a movement of the occupied d-bands slightly upwards and a broadening of the d-bandwidth, in contrast to some experiments. Neddermeyer (1981) suggested a drastic upshift of the 7. band - for that proposal there is no evidence in this work.
Because in this calculation exchange- and correlation-potentials are free from adjustable parameters, the author guesses, that in the difference between theory and experiment we have reached the limit of the local approximation (LDA).
