Psychological disability caused by stress is likely to affect cognitive and emotional functions, such as memory, attention, concentration, and decision making. These functions are essential in a train driver’s work, who is responsible for his or her own and others’ safety, and for this purpose requires optimal work capacity. Eighteen train drivers, 40 – 56 years old, most of them with long work ex
This paper presents a hybrid interconnect network consisting of a local network with dedicated wires and a global hierarchical network. A distributed memory approach enables the possibility to use generic memory banks as routing buffers, simplifies the implementation and reduces the area requirements of routers. A SystemC simulation environment (SCENIC) has been developed to simulate and instrumen
Popular Abstract in Swedish Denna avhandling fokuserar en religiös aktör i det civila samhället under en konfliktfylld tid. Judiska, muslimska och kristna barn studerade tillsammans i anglikanska missionsskolor under den brittiska mandattiden i Palestina. Jerusalem var då etniskt och religiöst delat. Det anglikanska utbildningsprojektet var en del av den Anglikanska kyrkans försök att främja konflThis thesis concerns a religious actor in the civil society in times of violent conflict. During the British Mandate period in Palestine, Jewish, Muslim and Christian children studied together at Anglican missionary schools. At this time Jerusalem bore all the imprints of ethnic and religious separation and division. The Anglican educational project became part of the efforts made by the Anglican
Use of Fire Safety Engineering (FSE) has increased substantially during the last decades. In the beginning fire safety engineering was mainly used for fire performance based design of buildings but recently new areas such as marine transport have appeared as new applications for fire safety engineering. So on one hand we have the increasing use of FSE. On the other hand we have the introduction of
This paper provides design experience based on 2D FE electromagnetic and heat transfer analysis that are used to support product development. An induction in-roll heater is analyzed, tested and verified. The scientific challenge is to develop fast and fair models to provide design guidelines for layout specification, material selection and performance estimation. The transferred energy capability
Popular Abstract in Swedish Cellulosa och stärkelse är naturligt förekommande polysackarider, som är uppbyggda av långa rader av flera tusen sammanbundna glukosmolekyler. De är biologiskt nedbrytbara, billiga och dessutom förnyelsebara, och används mycket som råvaror i läkemedels-, livsmedels-, textil-, pappers- och byggnadsindustrin. För att cellulosa och stärkelse ska kunna användas industrelltCellulose and starch are non-toxic, biodegradable and modifiable polymers. These properties have made them increasingly important in industrial products e. g. in pharmaceutical applications and in technical dispersions. By chemical modification of these polymers the physical and chemical properties of the polymer can be adjusted to suit a certain area of application. The characteristics of modifie
Gold nanoelectrodes with gaps of less than 10 nm were formed by conventional E-beam lithography on silicon substrates covered by Al2O3. Molecular films were deposited on the electrodes by Langmuir-Shaefer technique. The I-V curves of such systems show a suppressed conductance indicating a correlated electron tunnelling through the system. All measurements were made at room temperature.
Popular Abstract in Swedish Extracellulär matrix är namnet på det molekylära nätverk vilket finns mellan celler i flercelliga organismer. Det består av socker och proteiner organiserade i olika vävnadsspecifika nätverk. Två huvudformer finns, basalmembran och interstitiell extracellulär matrix. Basalmembran ligger som en tunn filt under epitel- och endotelceller, runt fettväv, muskler och periferaBasement membranes are sheet like structures underlying epithelial, endothelial, adipocytes, muscle and peripheral nerve cells. Laminins are an important family of basement membrane proteins implicated in various biological functions through their interactions with cell surface receptors. Laminins are trimers composed of a, b and g chains. Integrins, dystroglycan and other transmembrane glycoprote
Objectives. The aims of the present study were to analyze patient- and management-related predictors for outcome after open (OR) and endovascular repair (EVAR) of ruptured abdominal aortic aneurysm (rAAA). Design. Retrospective study. Materials. The in-hospital registry of Malmo University Hospital identified 162 patients operated on due to rAAA between 2000 and 2004. Methods. Patient- and managem
Popular Abstract in Swedish Många olika proteiner kan produceras med hjälp av rekombinanta DNA tekniker. Ofta sätts vektorn som kodar för det rekombinanta proteinet in i bakterien E. coli, då den är välkänd. Det är viktigt att producera mycket celler för att uppnå hög produktivitet. Detta görs genom att näringsämnet (ofta glukos) tillsätts kontinuerligt till en så kallad semisats reaktor. TillsatsThe recombinant DNA techniques have made it possible to produce many different proteins for a wide range of applications. The vector encoding for the recombinant protein is often inserted in the bacterium E. coli as it is a well studied and a well-known organism. To achieve a high productivity, it is important to reach a high cell density. This is obtained through fed-batch operation where the nut
Primers for amplification and sequencing of partial glyceraldehyde-3-phosphate dehydrogenase (gpd) gene were designed for lichenized fungi. The 5' gpd primer is most probably fungal specific, since a BLAST search in GenBank found identical sequences only from ascomycetous taxa, whereas the 3' gpd primer was more universal. Utility of the gpd primers and previously designed beta-tubulin primers was
A low intake of calcium is widely considered to be a risk factor for future fracture. The aim of this study was to quantify this risk on an international basis and to explore the effect of age, gender and bone mineral density (BMD) on this risk. We studied 39,563 men and women (69% female) from six prospectively studied cohorts comprising EVOS/EPOS, CaMos, DOES, the Rotterdam study, the Sheffield
This dissertation deals with the modern predicament of the Rabha or Kocha people, their survival in the forest and their quest for identity. Rabhas are one of India's indigenous or tribal people, and they live in the jungle tracts where the Himalayan mountains meet the plains of Bengal. When the area came under British rule and was converted into tea gardens and reserved forests Rabhas were forced
The most economical way to convert truck and bus DI-diesel engines to natural gas operation is to replace the injector with a spark plug and modify the combustion chamber in the piston crown for spark ignition operation. The modification of the piston crown should give a geometry well suited for spark ignition operation with the original swirling inlet port. Ten different geometries were tried on
A comparative analysis of the electron-hole (e-h) excitation mechanism of impurity luminescence has been performed for wide-gap oxides (WGO) and alkali halides crystals (AHC). A low quantum yield of scintillation in WGO with respect to that in AHC is connected with the high value of the average energy needed for the creation of an e-h pair in WGO. In AHC and many WGO, the width of a valence band E
