Dynamical effects of stellar mass-loss on a Kuiper-like belt

A quarter of DA white dwarfs are metal polluted, yet elements heavier than helium sink down through the stellar atmosphere on time-scales of days. Hence, these white dwarfs must be the currently accreting material containing heavy elements. Here we consider whether the scattering of comets or asteroids from an outer planetary system, following stellar mass-loss on the asymptotic giant branch, can

Self Calibrating Procedure for a 3D Force Observer

In robotic operations where a manipulator is involved, it is well-known that the quantities measured by a wrist force/torque sensor are corrupted by the dynamicsof the end effector and manipulator. To solve this problem,an observer, which fuses information from force sensors andaccelerometers, was designed recently in order to estimate the contact force exerted by a manipulator to its environment

Reallocation of risks within supply chains: The practice of enhanced liability clauses

Purpose of this paper The expression Enhanced Liability refers to clauses in a contract which obligation one of the partners to accept extended liability for future claims payments beyond normal standards of transport law, conventions or national standard terms and conditions for logistics service intermediaries, logistics service providers and carriers. This paper provides explanations and unders

Psychoanalytic Conceptions of the Mind in Drug Abusers : Methods Exploring Personality Disorders, Traits, and Defense Mechanisms

The purpose of the present thesis was to explore the theoretical and clinical implications of personality disorders (PDs), personality traits, and defense mechanisms in drug abusers diagnosed with psychosis and PDs. The prospect was, via four empirical studies and one paper of discussing methodology, to increase the psychodynamic understanding, which might improve the precision in planning treatme

The Argolid under Roman rule (31 BC - AD 600)

Popular Abstract in Swedish Avhandlingen behandlar det grekiska landskapet Argolis på östra Peloponnesos och vissa aspekter av livet där under drygt 600 år av romersk överhöghet. I området har man från den tiden funnit lämningar av städer, byar, villor och gårdar så väl som speciella anläggningar för framställning av olivolja, vin och keramik, dessutom badanläggningar, akvedukter, stenbrott, hamnaThis study focuses on the region of Argolid in the eastern part of the Greek Peloponnese during the Roman Imperial era, taking up a variety of aspects of life there based mainly on archaeological evidence. The introduction presents the study area and the background to the study. This is followed in the next chapter by a survey of the various kinds of sites of Roman date found in the Argolid. Citie

Time dependency behavior of granular materials

Theory of elasticity is the most used assumption in pavement design. Highway materials are neither elastic nor homogenous. Therefore there is a need for models which are based on more realistic assumptions. UGM shows time dependency in nature. This is reflected in a viscous response close to the surface and an elastic response deeper down the construction. Time dependencies of soils are relatively

Prayer in Peasant Communities : Ideals and Practices of Prayer in the Late Medieval Ecclesiastical Province of Uppsala, Sweden

The aim of this study has been to identify, explain and delineate praying among peasant communities in the ecclesiastical province of Uppsala, Sweden. Four aspects have been examined through the perspectives of ideals and practices, namely the standards of prayer, devotional prayer, prayer in times of need and prayer cultures. The standards of prayer considered the physical and mental behaviour of

Styrning av konsumenter mot miljövänligare och hälsosammare produkter : Information och ekonomiska incitament

Sammanfattning av projektets resultatInom projektet har vi studerat effekter av ekonomiska styrmedel för att nå en mer hållbar konsumtion från ett miljö- och hälsoperspektiv. Mer specifikt har vi studerat hur konsumenter ändrar sitt konsumtionsbeteende till följd av att vi ger dem information eller inför skatter och subventioner på olika varor. Vi har även studerat i vilken utsträckning konsumente
