Are Beautiful traffic environments safer than Ugly traffic environments?

To link aesthetics to traffic safety, the field of environmental psychology was consid-ered. A new model of driving behaviour was developed, based on Lewin’s (1951) equation, B = f (P,E) and by employing Küllers’ (1991) model of the basic emotional process. The employed model B = f (R(Road), U(Users), A(Task), P(Person)), states that driving behaviour (B) is related to the physical environment (R)

Efficacy and tolerance of a 12-week treatment with inhaled formoterol in patients with reversible obstructive lung disease

Formoterol, a new beta 2-agonist, and salbutamol were given as aerosols twice and four times daily, respectively, to patients with reversible obstructive lung disease. The study was controlled and double blind, and continued for 12 weeks. Ninety-nine patients from five study centers were included and 89 patients could be properly evaluated. The formoterol-treated patients used significantly less r

Conceptualization of solute transport using time domain reflectometry. A combined laboratory and field study

Solute transport in the unsaturated zone is a complex process. The first of the two objectives for this study was to examine how it could be conceptualized under different flow conditions. The second objective was to investigate how the time domain reflectometry (TDR) technique should be used in order to obtain high quality data from the soils studied. The TDR is an accurate instrument for water c

Incidence of a second tumor in hypopituitary patients operated for pituitary tumors

Recently, an association between increased blood levels of insulin-like growth factor I (IGF-I) and increased risks of prostate, breast, lung, and colorectal cancers has been suggested. As today adults with GH deficiency are subjected to GH substitution, there is a pressing need for baseline tumor incidence data. The aim of the study was to assess the risk for a second tumor in a cohort of 328 pat

Studenter med funktionshinder och deras erfarenheter av utbildningen vid Lunds universitet

Rapporten behandlar studenter med funktionshinder och deras utbildningserfarenheter. Dessa har kartlagts i en enkätundersökning och i en kvalitativ intervjuundersökning. Undersökningarna visade att funktionhindrade studenters samarbete med kurskamrater och lärare i allmänhet fungerade bra, men att de ibland hamnade i situationer som de uppfattade som kränkande. De vanligaste formerna av kränkning

Tributyl Citrate Oligomers as Plasticizers for Poly (lactic acid): Thermo-mechanical Film Properties and Aging

Poly (lactic acid), PLA, is a biodegradable thermoplastic that can be produced from renewable resources. The polymer is of interest for production of films for packaging applications. However, plasticization of PLA is required in order to obtain films with sufficient flexibility. PLA was blended with tributyl citrate (TbC) and two oligomers of TbC that were synthesized by transesterification of tr

Aggregation in a protein-surfactant system. The interplay between hydrophobic and electrostatic interactions

By precipitating a complex salt Ly(OS)(8) of the positively charged protein lysozyme and the anionic surfactant octyl sulfate OS-, one can generate a true ternary system: water-Ly(OS)(8)-NaOS. Using NMR diffusometry and U spectroscopy measurements the thermodynamic parameters of the association processes have been determined. The solubility product of the complex salt, K-s, is 10-(28) M-9.(1) On a

Contextualising Regional Innovation Systems in a Globalising Learning Economy: On Knowledge Bases and Institutional Frameworks

In order to advance the understanding of which types of regional innovation system represent effective innovation support for what kinds of industry in different regions analyses must be contextualized by reference to the actual knowledge base of various industries as well as to the regional and national institutional framework, which strongly shape the innovation processes of firms. Of special im

The role of cystatin C in cerebral amyloid angiopathy and stroke: Cell biology and animal models : cell biology and animal models

A variant of the cysteine protease inhibitor, cystatin C, forms amyloid deposited in the cerebral vasculature of patients with hereditary cerebral hemorrhage with amyloidosis, Icelandic type (HCHWA-I), leading to cerebral hemorrhages early in life. However, cystatin C is also implicated in neuronal degenerative diseases in which it does not form the amyloid protein, such as Alzheimer disease (AD).

The impact of nicotine on osseointegration - An experimental study in the femur and tibia of rabbits

Objectives: The aim of the present study was to analyze the effect of an enhanced systematic dose of nicotine on osseointegration of titanium implants. Material and methods: Sixteen female rabbits received either nicotine ( n = 8) or saline ( n 8) administered subcutaneously via mini-osmotic pumps for 2 months. The pump delivered 6 mg/kg/min of nicotine for the animals in the test group. Blood was

Protein kinase A-dependent and -independent stimulation of exocytosis by cAMP in mouse pancreatic B-cells

1. The mechanisms by which cAMP stimulates Ca(2+)-dependent insulin secretion were investigated by combining measurements of whole-cell Ca2+ currents, the cytoplasmic free Ca2+ concentration ([Ca2+]i) and membrane capacitance in single mouse B-cells maintained in tissue culture. 2. Cyclic AMP stimulated exocytosis > 4-fold in whole-cell experiments in which secretion was evoked by intracellular di
