The population of metastable states produced in relativistic-energy fragmentation of a U-238 beam has been measured. For states with angular momentum greater than or similar to 20h, a much higher population than expected has been observed. By introducing a collective component to the generation of angular momentum the experimental data can be understood. This is the first time that a collective de

1. The location in the spinal cord of the pathway mediating cutaneous nociceptive C fibre input to climbing fibres projecting to the forelimb area of the C3 zone in the cerebellar anterior lobe was investigated in pentobarbitone-anaesthetized cats. Lesions of the spinal cord at the segmental level of C3 sparing the dorsal funiculi (DF preparation) or lesions of the ipsilateral and part of the cont

Random PCR mutagenesis was applied to the Thermus thermophilus xylA gene encoding xylose isomerase. Three cold-adapted mutants were isolated with the following amino-acid substitutions: E372G, V379A (M-1021), E372G, F163L (M-1024) and E372G (M-1026). The wild-type and mutated xylA genes were cloned and expressed in Escherichia coli HB101 using the vector pGEM-T Easy, and their physicochemical and

The aim of this study is to try and explain the relationship between violence and the changes taking place in social spaces. Violence, in all its dimensions, has taken a central place in Latin American social life and has become an almost totally private issue. This implies a series of spatial and social transformations in the cities. The new effects of violence influence social and ethnic segrega

The thesis deals mainly with offshore engineering related problems where the dominant source of uncertainty is related to the loading. Loads arise from environmental random processes; e.g. waves, currents and winds. Complex as they are, such processes beg the consideration of randomness whence the need of associating probabilistic models to the engineering problems treated here. Two different typ

Denna rapport sammanfattar och reflekterar över lärdomar från tolv Balanced Scorecard projekt. Rapporten skall i första hand läsas som ett bidrag till diskussionen om relevansen av Balanced Scorecard i utvecklingen av kommunala sektorns styrsystem. Vad som förmedlas är en illustration av och reflektion över styrmodellens förtjänster och till¬korta¬kommanden. Rapporten är ett resultat av ett utvec

Popular Abstract in Swedish Många har fascinerats av det mystiska Mayafolket som byggde fantastiska städer med tempelpyramider, astronomiska observatorier och bollplaner djupt inne i djungeln i Guatemala och Mexiko. Vilka var de som utvecklade denna högkultur med hieroglyfer och avancerade kalendrar? Denna avhandling presenterar Mayaindianernas religion och historia. Frågor som söker sina svar är This thesis deals with Maya religion and history. The Books of Chilam Balam is the collective title of a body of texts ascribed to the Jaguar Prophet. They are written in the Yucatec Maya language, and tell the reader about Yucatec Maya cosmology, rituals, prophecies, calendars, medicine and they are as well considered as Yucatec Maya emic historiography. These manuscripts are considered enigmatic

The sensitivity of the rat submaxillary gland was examined 3-4 weeks after either parasympathetic decentralization or sympathetic decentralization or denervation. The threshold doses for secretion of saliva of parasympathomimetic (methacholine) and sympathomimetic (noradrenaline, adrenaline, phenylephrine and isoprenaline) drugs were estimated and the amount of saliva secreted in response to supra

Over the last three and half decades Sweden have provided development aid to Ethiopia. This aid was used to expand Ethiopia's educutional system, public health service and agricultural production. This empiricaI study reveals Ethiopia's response to Swedish aid and its influence. Providing and receiving aid explains the existence of disparity among sovereign states. In spite of the demonstrative i

Popular Abstract in Swedish Parkinsons sjukdom är den näst mest vanliga neurodegenerativa sjukdomen och den drabbar 2% av befolkningen över 65 år. Sjukdomen kännetecknas av en gradvis ökad förlust av dopaminproducerande nervceller. Symtomen tilltar successivt och leder framförallt till allvarliga fördröjningar i rörelsemönstret. Dessvärre, när de första symptomen väl upptäcks, så har redan 50% av Parkinson's disease (PD) is the second most common neurodegenerative disease and affects 2% of the population over 65 years of age. The disease is characterized by the progressive loss of dopaminergic neurons. Over time, symptoms increase and, in particular, lead to a dramatic slowness of movements. Unfortunately, when the fi rst symptoms are discovered, more than 50% of the dopaminergic neurons a
