Identification of Excited States in the Tz=+1/2 Nucleus 75Rb: The Quest for Experimental Signatures of Collective Neutron-proton Correlations
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

Driving pattern in urban areas - descriptive analysis and initial prediction model
Driving pattern, i.e. the speed profiles of vehicles, was studied in connection with variables in the driver-car-environment system. Data were collected using five measuring cars that were driven by 29 randomly chosen families for two weeks each. The cars were equipped with data-logging devices that enabled studies of the speed and acceleration patterns of the vehicles as well as engine speed and

Bulk and surface charge states of K3C60
We detect a significant angle-dependence in the core level and valence line shapes of photoelectron spectra of single crystal K3C60. This allows the identification of bulk and surface components in the data, and allows us to explain the anomalous line shapes observed for this system. The states near the Fermi level are associated with the bulk of the sample. There is strong evidence of an insulati
Elevers interaktiva lärande vid problemlösning i grupp : En processtudie
Popular Abstract in Swedish Denna studie rapporterar ett undervisningsförsök i en 8:e klass (age 14-15) med 20 elever. Eleverna har bearbetat en naturvetenskaplig problemställning om växthuseffekten och jordens globala uppvärmning utifrån ett problemlösande och informationssökandarbete i grupp. Deras uppgift har varit att beskriva de fenomen och faktorer som påverkar jordens globala temperatur i oThis study gives an account of a teaching situation in the eighth grade with 20 student's aged 14-15. The students have worked with a scientific problem focussed on the greenhouse effect and the earth's global warming, based on a problem solving and information seeking way of working in groups. Their task has been to describe the phenomena and factors that influence the earth's global temperature
Sprickbildning i puts på isolering : inledande laboratorieförsök och parameterstudier
I denna rapport beskrivs några av de mekanismer som kan leda till sprickbildning. Rapporten behandlar enbart de fuktrelaterade mekanismerna. Samma mekanismer kan även relateras till temperaturrörelser. Det som förorsakar sprickor är förhindrade rörelser hos putsen.
Distribution of extraterrestrial chromite in Middle Ordovician Komstad Limestone in the Killeröd Quarry, southern Sweden
Sediment-dispersed extraterrestrial chromite grains (63-355 mu m) have been recovered in a section across the Arenig-Llanvirn transition in the Killerod quarry in southeastern Scania. Previous studies of the same stratigraphic interval in the Orthoceratite Limestone at Kinnekulle, ca. 350 km to the north in Vastergotland, have shown a two orders of magnitude increase in extraterrestrial chromite b

An Optimisation Approach to Cartographic Generalisation
Popular Abstract in Swedish Idag lagras allt fler kartor digitalt och nya metoder krävs för att förbättra denna digitala hantering. Ett område som studerats under senare tid är automatiska metoder för kartografisk generalisering. Kartografisk generalisering innebär att man förenklar informationen i en karta för att göra den mer lättläst i den önskade skalan. Denna avhandling beskriver en optimerinCartographic generalisation is the process of simplifying a representation to suit the scale and purpose of a map. As such, generalisation has always been a central part in map production. This thesis is a contribution to the ongoing work on automating cartographic generalisation. Two topics are treated: optimisation methods in graphic generalisation, and propagation of updates between cartographi

Implementation of the DTMROC-S ASIC for the ATLAS TRT Detector in a 0.25μm CMOS technology
The DTMROC-S is a 16-channeI front-end chip developed for the signal processing of the ATLAS straw tube detector, TRT. Due to a highly radioactive environment, the chip is fabricated in a commercial 0.25μm CMOS technology hardened by layout techniques and, in addition, a special methodology was used to improve the circuit's robustness against Single Events Effects (SEE) caused by ionizing particle

Multilayers at the surface of solutions of exogenous lung surfactant: Direct observation by neutron reflection
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

Variability of shore and shoreline evolution
Shore and shoreline evolution both due to natural and human-induced causes or factors can be variable over a wide range of different temporal and/or spatial scales. Our capability to understand and especially predict this variability is still limited. This can lead to misinterpretation of coastal change information, which hampers informed decision making and the subsequent design and implementatio
Limited protective effect of the CCR5 Delta 32/CCR5 Delta 32 genotype on human immunodeficiency virus infection incidence in a cohort of patients with hemophilia and selection for genotypic X4 virus
The relationship among CCR5 genotype, cytomegalovirus infection, and disease progression and death was studied among 159 human immunodeficiency virus (HIV)-infected patients with hemophilia. One patient (0.6%) had the CCR5Delta32/CCR5Delta32 genotype (which occurs in similar to2% of the Scandinavian population) and a rapid disease course. His HIV V3 region contained genotypic features attributable
Comparison of quantitative ultrasound measurements in calcaneus with DXA and SXA at other skeletal sites: a population-based study on 280 children aged 11-16 years
We performed ultrasound measurements (QUS) of the calcaneus in a population-based setting on 280 healthy children, aged 11-16 years, from a small urban area in southern Sweden. The results are compared with dual-energy X-ray absorptiometry (DXA) measurements in the total body, the lumbar spine and the hip, as well as single-energy X-ray absorptiometry (SXA) of the forearm. Normative data and corre
