In this study the feasibility of applying proton-induced X-ray emission spectroscopy (PIXE) to the trace element analysis of human tooth enamel and dentine is investigated. Detection limits on the order of 1–10 ppm are obtained. Depth yields for different elements and proton energies are discussed. Enhancement calculations show that the effect for PIXE analysis is less important than for X-ray ind

The practice of service encounters in a district court, a home for the elderly, and a hotel Service management research places the service encounter in a central position. It is highlighted as a key event that involves the simultaneous production, consumption, and marketing of the services produced by the operation. However, in this research there is a tendency to discuss the service encounter in

Popular Abstract in Swedish Har alkohol någon skadlig effekt på människoskelettet? Vid Avdelningen för ortopedi på Universitetssjukhuset MAS har vi studerat detta problem och min avhandling är ett försök att besvara frågan. Siffrorna över konsumtionsmönstret för alkohol är osäkra - i Malmö är minst 9% av den manliga befolkningen högkonsumenter. Enligt nyligen publicerade data dricker män mest i åThe influence of alcohol on bone metabolism, fracture and fracture healing was evaluated in men and male rats by measurements of bone mineral density (BMD), biochemical markers and biomechanical testings. Retrospectively, 199 male patients hospitalized for tibia shaft fractures were studied. Forty-nine were judged as problem drinkers. Abusers were more prone to sustain oblique fractures. The heal

This edited volume brings together scholars positioned in and outside of China, including former Chinese journalists, in a comprehensive and in-depth study of Chinese investigative journalists' dreams, work practices, and strategies. It is the first book that systematically addresses the roles and values of Chinese investigative journalists in different types of media, in the process addressing to

Analog decoders are constructed based on interconnecting CMOS Gilbert vector multipliers using transistors operating in the sub-VT region. They are seen as an interesting alternative to digital implementations with a low transistor count and a potential for a very low power consumption. Analog implementation makes the circuit sensitive to mismatch, requiring careful transistor sizing. A simulation

In this study, a two-dimensional numerical model for water flow and solute transport, Hydrus-2D, was used to investigate the impact of landfill cover thickness and the antecedent water content (Ө) of the soil beneath the landfill on the chloride percolation below the landfill. Series of simulation scenarios were performed using season varying climatic data during a 30-year period including two var

As a cost-effective option for Cloud consumers, spot service has been considered to be a significant supplement for building a full-fledged market economy for the Cloud ecosystem. However, unlike the static and straightforward way of trading on-demand and reserved Cloud services, the market-driven regulations of employing spot service could be too complicated for Cloud consumers to comprehensively

Monl torlng of trace gases in the atmosphere has been performed wl th differential absorption lldar and differential optical absorption spectroscopy. A new mobile differential absorption lldar system has been constructed. It is described in detail and examples of 502 and N02 measurements are given. Studies of the N02 concentration distribution in an urban area during a temperature inversion were p

Abstract in SpanishEste texto responde a una necesidad izquierdista, pero de una izquierda que por razones obvias ya no se encuentra. Trata de buscar todas las respuestas; de no renunciar a una visión compleja pero global, capaz de transformase en una “guía para la acción”. Se trata de un texto con respuestas, planes, ideas claras, objetivos, convicciones. Hasta hace no muchos años, el mundo era r
