This study aims to assess the normal inflow of extraterrestrial chromite to Earth. The results from the investigationare compared to earlier studies of middle Ordovician Orthoceratite Limestone in which 1 - 3 extraterrestrial chromitegrains ( >63 ?Êm ) per kilogram limestone were found. These values have been interpreted as evidence of a twoorders of magnitude increase in the flux of extraterrestrial matter to Earth during a part of middle Ordovician.From an early Paleocene marine sedimentary sequence with known sedimentation rate in Zumaia, northernSpain, 90,5 kilogram of condensed limestone, dated to about 63 Ma, was sampled. The limestone was dissolved inhydrochloric- and hydrofluoric acid and the residue was sieved and searched for opaque minerals under the binocularmicroscope.

The Division of Language and Communication at Chalmers uses a web-based language tool, named EngOnline, to teach English grammar. The language tool suffers from some shortcomings. These include stability problems and an outdated interface but, above all, there is no documentation. Because of the lack of documentation and EngOnline?s need of maintenance, the Division of Language and Communication has decided to replace the language tool with a new and well documented one.The new language tool was developed using an agile work process; detailed documentation was replaced with more efficient communication.

This study aims to illustrate the Leader approach and analyze the work of collaboration development within Leader. The idea has also been to describe some of the difficulties that might be encountered in this type of development work. By highlighting the strengths and weaknesses of this approach we hope to enhance the chance that future work in similar projects can be implemented more easily. Leader is a tool and methodology used in the European Union (EU) for work on sustainable rural development and it has been used since 1991. The purpose of Leader is that by supporting rural projects they will gain social capital and development in the rural communities.

Syftet med undersökningen är att få förståelse för faktorer som påverkar motivationen hos personalen på MSB (Myndigheten för Samhällsskydd och Beredskap). Undersökningen belyser dels den psykosociala arbetsmiljöns påverkan och dels ledningens betydelse för de anställdas motivation. I teoriavsnittet behandlas tre olika block: Motivation, Psykosocial arbetsmiljö och slutligen Management. Dessa tre block ligger således till grund för undersökningen och själva uppsatsen. För att få en djupare förståelse om ämnet har en kvalitativ metod valts, med intervju som datainsamlingsmetod.

Min uppgift var att under åtta veckors tid genomföra den konceptuella fasen i en pipeline mot ett kortfilmsprojekt. Uppgiften var att från en illustrerad barnbok skapa 3D miljöer med avsikt att i första hand användas konceptuellt för kommande produktion. Betoningen låg på att fånga karaktär och stämning för miljöerna och rättvist spegla ursprungsmaterialet och samtidigt utveckla det till att fungera konstnärligt och praktiskt i ett 3D sammanhang. Materialet jag avsågs utgå ifrån heter ?Viktor bygger en bro? av Jan Lööf, en barnbok publicerad 1972 av BonnierCarlsen.

As the final course in the education ?University Diploma Programme for Process Operators? there is a thesis in cooperation with a company required.This thesis is about operator maintenance and 5S made at Metsä Board in Husum.In this report you can read my opinions and conclusions based on literature studies and the interviews that have been made with the staff at PM6 (the paper machine).I chose to focus on the theory of lean, 5S and operator maintenance because it covers the area of this thesis.The operators shall do their rounds to make sure that the equipment works fine. They shall also write down things that they notice in a checklist. This is not done as it should be and the question is: can this be solved by using 5S?My conclusion of this thesis are:Better review of the task so that everyone is involved.

Purpose: To explore how the changes in work life, here represented and depicted through the concepts of knowledge work and knowledge worker, have been incorporated in the official psychosocial work environment discourse in Sweden. Methodology: Critical discourse analysis, contrasting the official psychosocial work environment discourse to literature on knowledge work and knowledge worker, to explore how employees, employers and their relations are constructed within these two discourses; focusing identity, autonomy and power. Using the constructions to make visible how they are articulated, used and dealt with in a real life case from the Work Environment Authority. Theoretical perspectives: Our social world is socially constructed and language is the main tool for constructing it. Discourse analysis is thus not just a tool for deconstructing texts but also for enhanced understanding of our construction of the world and our ability to communicate about it.

Syftet med studien var att få inblick i hur arbetet med rättvis bedömning och betygsättning kan gestaltas i gymnasieskolan ur ett elevperspektiv. Fem elever från fyra gymnasieskolors studieförberedande program intervjuades. Resultatet visade för det första att tre olika bedömningsformer kan urskiljas: 1) Summativ bedömning; 2) Summativ bedömning med formativa inslag; 3) Formativ bedömning. För det andra sker för de flesta av eleverna ingen större involvering i bedömningsprocessen: eleverna blir bedömda. För det tredje anser de flesta av eleverna att den återkoppling de får av läraren är bristfällig och otillräcklig.

Studier har visat att chefer har ett stort inflytande på de anställdas välbefinnande. I dagens hektiska arbetsliv är detta något som bör tillvaratas då de anställdas välbefinnande hotas på grund av de arbetsförhållanden de befinner sig i. Denna studie gjordes i syfte att undersöka hur ledarskap upplevs inverka på de anställdas välbefinnande. Halvstrukturerade intervjuer tolkade med tematisk analys visade att ledarskapet upplevdes ha en inverkan på de anställdas välbefinnande. Vilken typ av ledarstil som användes upplevdes spela en roll för välbefinnandet och speciellt viktiga komponenter för att utföra ett hälsofrämjande ledarskap var kommunikation, feedback och socialt stöd.

The use of a bit in the mouth of a horse is being increasingly questioned with respect to its actual function, and is sometimes judged an obsolete instrument of control with potential to injure the horse. The objective of the research presented herein was twofold; firstly, to investigate the actual pressure load in the mouth of the horse with regard to oral health issues, and, secondly, to investigate whether this could be a viable method to objectively measure strength exerted by a rider/driver to the mouth of the horse especially with regard to training regimes. From the results, it is evident that these newly developed sensors have a future in equine research, although they are still under development. They can be useful both as a pedagogic teaching instrument, providing instructor and pupil with instantaneous, objective feedback on the contact between hand and mouth, as well as an aid in measuring pressure loads from our common bits. .

The purpose of this study is to understand the collaboration between school and social services. The primary focus of this study is the subject of interaction. The study analyzes how confidentiality affects collaboration between school and social services and examines what effect the organizations? different roles have on collaboration. The method used is qualitative interviews and the gathered empirical data has been analyzed using theories of discretion and street-level bureaucracy.

The main purpose of this thesis has been to address the problem connected with conservation ofspecific objects in historic buildings that have a protected building status. The immaterial demandsand environmental concerns of a place of cultural significance are discussed as opposed to the welladaptedsetting of a museum, with regard to long-term preservation. In an authentic interior of acertain era, large-scale individual treatments of the objects that define it and regulations forconservation-related reasons, may not be considered a worth-while effort, as it is often the integrityof the environment as a whole that has been declared as significant. To investigate the relationshipbetween object and its context, a case study has been conducted by examination of the propertycalled ?Curmans villor?, located in the seaside community called Lysekil.

The main objective of this research was to study how increased arterial oxygenation by the use of Pulsed Inhaled Nitric-Oxide (PiNO) influenced the metabolic and cardiovascular parameters on horses undergoing acute abdominal surgery because of colic. The parameters blood lactate, blood glucose, pH and heart rate were evaluated before and during anesthesia and closely after recovery. The study showed that blood lactate concentrations decreased significantly during anaesthesia in horses treated with PiNO compared to non-treated horses. It was also seen that the lactate concentration decreased most in horses with the highest levels before PiNO treatment. Since enhanced oxygen extraction ratio was evident in the PiNO group, improved oxygen delivery to the tissue may be a possible explanation for the improved situation.

Ever since ABB has begun diecasting their rotors instead of permanent mold casting it,variation in the quality of the cast has arisen. Diecasting is performed in three differentmachines, M1, M2, M3 with 400, 660 respectively 800 tons of die locking pressures.The aim of this thesis is to answer the following questions:What is the ?right? cast quality? How is the right quality achieved?For sizes 160-180 solutions will be proposed that consider eccentricity between thelaminate and the short circuit ring as well as elimination of the thin Al film that appearson the outer periphery of the rotors.Through considering the statistic material the most often diverging rotor type has beenidentified and one of the actual rotors has been sent to a laboratory to be analyzed inorder to establish the current defects. The result of the analysis shows that there areplenty of gas- and oxide-porosity.It has been proved that every time the dies temperature decreased below 120°C thecontent of gas porosity increased. It is due to rapid solidification of metal that flowsthrough the ?cold? laminate.It has confirmed that enhanced porosity in squirrel cage causes high impedance in therotors.
