Centrums roll och funktion har förändrats över tiden under perioder av urbanisering, suburbanisering, desurbanisering och reurbanisering. Transportmedelsutvecklingen och olika stadsplaneringstraditioner har påverkat såväl stadsstrukturen som centrums uppbyggnad. Det övergripande syftet med boken är att belysa hur olika bebyggelse- och trafikmässiga faktorer samverkar och formar centrum och centrum

Proteins fold on a mu s-ms time scale. However, the number of possible conformations of the polypeptide backbone is so large that random sampling would not allow the protein to fold within the lifetime of the universe, the Levinthal paradox. We show here that a protein chain can fold efficiently with high fidelity if on average native contacts survive longer than non-native ones, that is, if the d
Popular Abstract in Swedish Inom hälso- och sjukvården betonas att vården ska ges utifrån ett patientorienterat sätt. Om sjuksköterskor skall kunna ge patienten god omvårdnad, måste de själva ha en god arbetssituation. Det blir allt vanligare att sjuksköterskor i arbetet utsätts för en mängd negativa psykiska påfrestningar, såsom hot och våld, som kan leda till stress. Stress kan också relateras tThe purpose of group supervision in nursing care is to understand nurses’ experiences from real care settings and to structure these in a professional and personal context. An interventional and longitudinal method of research was chosen in this study of group supervision in nursing care. The overall aim of the present study was to examine and investigate how psychiatric nurses’ professional compe
In this work we discuss different factors governing coil-globule coexistence in the compaction process of DNA. We initially analyse the role played by fluctuations in the degree of binding of an external compacting agent in the conformational behavior of the chain backbone. The analysis relies both on Monte Carlo simulation results and simple statistical approaches. Compacting agents of various bi
Background: Recent studies revealed that many mammalian protein- coding genes also transcribe their complementary strands. This phenomenon raises questions regarding the validity of data obtained from double-stranded cDNA microarrays since hybridization to both strands may occur. Here, we wanted to analyze experimentally the incidence of antisense transcription in human cells and to estimate their
We predict that in a narrow gap III-V semiconductor quantum well or quantum wire, an observable electron spin current can be generated with a time-dependent gate to modify the Rashba spin-orbit coupling constant. Methods to rectify the so generated ac current are discussed. An all-electric method of spin-current detection is suggested, which measures the voltage on the gate in the vicinity of a tw
The spin-state of cytochrome b559 (Cyt b559) was studied in photosystem II (PSII) membrane fragments by low-temperature EPR spectroscopy. Treatment of the membranes with 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) converts the native low-spin (LS) form of Cyt b559 to the high-spin (HS) form characterized with the g= 6.19 and g= 5.95 split signal. The HS Cyt b559 was pH dependent with the amplitu
OBJECTIVE - To elucidate whether family characteristics and stressful life events were associated with onset of autoimmune type 1 diabetes in young adults. RESEARCH DESIGN AND METHODS - This investigation was based on a nation-wide study (Diabetes Incidence Study in Sweden) of newly diagnosed patients aged 15-34 years. Patients clinically classified as type 1 diabetic with antibodies to islet cell
The interaction between dye and semiconductor is a central aspect of dye-sensitized solar cells. We have in this paper studied the binding of the common ligand bi-isonicotinic acid (4,4'-dicarboxy-2,2'-bipyridine) to TiO2 anatase (101) surfaces by means of quantum chemical calculations. Different adsorption models were studied with carboxyl oxygens binding to surface Ti atoms, and the acidic proto
We generalize the concept of a 2-coloring of a graph to what we call a semi-balanced coloring by relaxing a certain discrepancy condition on the shortest-paths hypergraph of the graph. Let G be an undirected, unweighted, connected graph with n vertices and m edges. We prove that the number of different semi-balanced colorings of G is: (1) at most n+1 if G is bipartite; (2) at most m if G is non-bi
Abstract in Undetermined The approach of the mental landscape enlarges the perspectives for interpreting sites and settle- ments. In the Kullen district sites and settlements is theorized by breaking down the dichotomi- es of Mesolithic and Neolithic and the archaeologically constructed borderline between the periods. The terminology and the interpretation of site and settlement need to be extende
A discussion of what constitutes a good human being.
Out of Quality of Service reasons, higher priority shall in cellular networks be assigned to ongoing connections than to new call attempts. This can be accomplished through reserving a portion of the bandwidth assigned to a cell exclusively for high priority connections. A low priority call is only admitted to a cell if the unoccupied bandwidth in the cell following the acceptance of the call exce
OBJECTIVE: To illuminate the lived experience of women facing the threat of lossing their newborn child and then experiencing the reality of their infant's death. STUDY DESIGN: Sixteen women were interviewed approximately 2 years after the death of their infant using a hermeneutic phenomenological approach. FINDINGS: The main theme was ambivalent transition into motherhood. The women went through
The distribution of neuropeptide Y (NPY)-immunoreactivity was investigated in the rabbit maxillary sinus and adjacent ganglia. A moderate supply of NPY-containing nerve fibers occurred around seromucous glands and a denser supply around small blood vessels. Only a few immunoreactive nerve fibers were seen beneath the epithelium. Double immunostaining showed that vasoactive intestinal peptide (VIP)
A distillation unit has been designed for a capacity of 73 t/h of condensate and for at least 90% recovery of the contaminating organics. This unit consists of three columns: a primary stripper to remove volatile organics and two upgrading columns to purify the methanol and furfural byproducts. Three different energy-saving alternatives for satisfying the energy requirements have been studied: ut
