Excited states in the T-z-1/2 nucleus Rb-75 were observed for the first time using the Ca-40(Ca-40,alpha p) reaction at 128 MeV. Identification was achieved using events detected by the Daresbury recoil separator in coincidence with gamma rays detected in the 45 element EUROGAM I Ge-detector array. Threefold events were used to build a decay scheme which consists of two rotational bands observed t

Pharmacy-grade exogenous lung surfactant preparations of bovine and porcine origin, dispersed in physiological electrolyte solution have been studied. The organization and dynamics at the air/water interface at physiological temperature was analysed by neutron reflection. The results show that a well-defined surface phase is formed, consisting of a multilayer structure of lipid/protein bilayers al

The European Directives on personal protective devices have increased the interest in protective and functional properties of work clothing and intensified standardisation work as well as stimulated research in areas with limited knowledge. There is a long tradition of research and information exchange in the Nordic countries on the subject. The NOrdisk KOrdineringsgruppe om BEskyttelseskläder som

In this paper the Petersen and composition matrices that modellers are now familiar with are used as a basis to construct interfacing models between subsystems considered in wastewater treatment. Starting from continuity considerations and a set of transformation reactions between components used in the two models of the subsystems to be interfaced, a set of linear algebraic equations needs to be

During the last decades a striking decline has been observed for wild bees throughout central and north-western Europe, including Sweden. in an area of 64 km' in the parish of Stenbrohult, southern Smaland Andrena hattorfiana, Andrena humilis, Nomada armata and Panurgus hanksianus were studied (in Sweden red-listed as VU, EN, EN and VU). We present occurrence patterns in relation to habitat types

The aim of this report is to present some of the variable uncertainties associated with the dimensioning of fire protection in buildings and risk analysis in buildings (with respect to fire). A method for assessing the fire frequency in a building is presented along with examples of how the assessed fire frequency can be improved using fire data from a specific building. The probability of differe

An unexpected discovery of Caloplaca lobulata in Tasmania is presented. This species which earlier seemed rather widely spread in central Europe have today become an extremely rare and endangered element in the European lichen flora. The generic affinity with other closely related species is briefly discussed.

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
