Stockholmarnas resvanor – mellan trängselskatt och klimatdebatt
Popular Abstract in Swedish Avhandlingen belyser vad resvanor är, hur storskaliga trafikreglerande åtgärder tas emot samt hur storstadsbornas resmönster kan bli miljömässigt hållbara på lång sikt. Jag diskuterar dessutom problem och möjligheter i skärningsområden mellan olika vetenskapliga discipliner som griper sig an dessa frågor. De viktigaste slutsatserna gäller för det första det vetenskapligThis thesis examines the concept of travel habits, public responses to large-scale traffic congestion regulations and how travel patterns of urban dwellers can be made environmentally sustainable in the long term. It also examines the interrelationships of different scientific disciplines dealing with urban travel. The main conclusions relate to the scientific concept of habit. This concept and th
Experience influences oviposition behaviour in two pyralid moths, Ephestia cautella and Plodia interpunctella
We investigated the importance of experience for oviposition behaviour in two pyralid moths, the almond moth, Ephestia cautella, and the Indian meal moth, Plodia interpunctella. We used two diets one based on wheat and the other consisting of nut-containing chocolate. Larvae were reared in one of the two diets (larval feeding) and then adults were exposed to the two diets during and after eclosion
The genus Pseudexechia Tuomikoski re-characterized, with a review of European species (Diptera: Mycetophilidae)
The genus Pseudexechia Tuomikoski is re-characterized and described, including a thorough morphological study of the male and female terminalia, providing homology assessment of the various parts and substructures. The 25 currently known species of Pseudexechia are tentatively grouped into four species groups that are characterized mainly by structures of the male terminalia: the canalicula group
An Electrochemical Study into the Interaction between Complement-Derived Peptides and DOPC Mono- and Bilayers
Electrochemical methods employing the hanging mercury drop electrode were used to study the interaction between variants of the complement-derived antimicrobial peptide CNY21 (CNYITELRRQH ARASHLGLAR) and dioleoyl phosphatidylcholine (DOPC) monolayers. Capacitance potential and impedance measurements showed that the CNY21 analogues investigated interact with DOPC monolayers coating the mercury drop
Subglacial decoupling at the sediment/bedrock interface: a new mechanism for rapid flowing ice
Abstract in UndeterminedOn millennial or even centennial time scales, the activity of rapid flowing ice can affect climate variability and global sea level through release of meltwater into the ocean and positive feedback loops to the climate system. At the surge-type glacier Bruarjokull, an outlet of the Vatnajokull ice cap, eastern Iceland, extremely rapid ice flow was sustained by overpressuriz
Mercaptobenzothiazole or the mercapto-mix: which should be in the standard series?
Mercaptobenzothiazole (MBT) compounds are well known contact allergens. To detect rubber allergic patients we use both MBT (2% in petrolatum) and a mercapto-mix with 4 constituents of 0.5% each in our standard series. In this article the EECDRG presents data of in total 32 475 consecutive tested patients attending the respective contact dermatitis clinics from 11 centres in Europe to determine if
Exploring User Requirements for Non-visual Mobile Navigation Systems
This paper describes an explorative user study of how two different user groups experience current, as well as envisioned new mobile navigation systems. Two groups have been the primary target in this study; a group of elderly people and a group of relatively young university students that were visually impaired. The study consisted of three parts: a focus group/test, a diary study and a design wo
Fabrication of cantilever based mass sensors integrated with CMOS using direct write laser lithography on resist
A CMOS compatible direct write laser lithography technique has been developed for cantilever fabrication on pre-fabricated standard CMOS. We have developed cantilever based sensors for mass measurements in vacuum and air. The cantilever is actuated into lateral vibration by electrostatic excitation and the resonant frequency is detected by capacitive readout. The device is integrated on standard C
Relative concentrations of hK2/PSA mRNA in benign and malignant prostatic tissue
BACKGROUND. Prostate-specific antigen (PSA/KLK3) and human kallikrein 2 (hK2/KLK2) belong to the human kallikrein gene family. These two highly homologous genes are specifically expressed in the prostate under androgen control. Expression of these is regulated by similar mechanisms but changes in their relative expression have been observed in prostate cancer. METHODS. We determined the relative l
The potential of native parasitoids for the control of Mexican bean beetles: A genetic and ecological approach
Bruchid beetles in the genus Zabrotes are important pests of field and stored beans all around the world and cause enormous economical losses in Mexico and Central America. Native parasitoids have been successfully used to suppress infestations by bruchid beetles in Africa, but few studies have assessed their potential to reduce seed damage in the New World and no successful biological control pro
The use of holographic interferometry and electron speckle pattern interferometry for diffusion measurement in biochemical and pharmaceutical engineering applications
In this review holographic interferometry and electron speckle pattern interferometry are discussed as efficient techniques for diffusion measurements in biochemical and pharmaceutical applications. Transport phenomena can be studied, quantitatively and qualitatively, in gels, liquids and membranes. Detailed information on these phenomena is required to design effective chromatography bioseparatio
Causes and timing of the 8200 yr BP event inferred from the comparison of the GRIP Be-10 and the tree ring Delta C-14 record
We analyse the 8200 yr BP cold event by comparing the high-resolution Be-10 record from the GRIP ice core from Central Greenland with the well-known tree ring Delta(14)C record. By transferring the absolute dated tree ring chronology to the ice core time scale, we show that the coldest phase in the GRIP record occurred around 8150 yr BP. Furthermore, this method allows us to disentangle production
Effect of genetic variation on the tryptic hydrolysis of bovine beta-lactoglobulin A, B, and C
The structure, stability, and hydrolysis characteristics of beta-lactoglobulin (LG) A are different from those of either beta-LG B or beta-LG C. Purified samples of these proteins were hydrolyzed with trypsin and the rates of loss of native monomeric beta-LG structure were measured using sodium dodecyl sulfate PAGE. At the same time, the appearance of many individual peptides were identified and f
Outcome of Basic body awareness therapy. A randomized controlled study of patients in psychiatric outpatient care
The aim was to study the outcome of Basic Body Awareness Therapy (Basic BAT) added to treatment as usual (TAU) compared to TAU only, for patients with mood, somatoform or personality disorders in psychiatric outpatient services. Seventy-seven patients were randomized to Basic BAT and TAU (n=38) or TAU only (n=39). Patients were assessed at baseline and after 12 sessions of Basic BAT, 3 months afte
Enhanced Transcription of Contractile 5-Hydroxytryptamine 2A Receptors via Extracellular Signal-Regulated Kinase 1/2 after Organ Culture of Rat Mesenteric Artery.
A Century with the Sitz im Leben. From Form-Critical Setting to Gospel Community and Beyond
Methylprednisolone treatment in acute spinal cord injury: the myth challenged through a structured analysis of published literature.
Total parenteral nutrition influences both endocrine and exocrine function of rat pancreas
The aim of this study was to examine the effect of total parenteral nutrition (TPN) on the endocrine and exocine function of the pancreas. Endocrine function was investigated using an intravenous glucose tolerance test (IGTT) in rats with TPN for 7 or 14 days. Exocrine function was evaluated by measuring amylase secretion from isolated acini as well as pancreatic weight, water content, protein, an
Identification of a novel amplicon at distal 17q containing the BIRC5/SURVIVIN gene in malignant peripheral nerve sheath tumours
Previous studies have suggested that amplification of genes, notably the TOP2A gene, on chromosome arm 17q may be important for the development of malignant peripheral nerve sheath tumour (MPNST). In order to study the frequency, distribution, and chromosomal organization of rearrangements at 17q, interphase and metaphase fluorescence in situ hybridization (FISH) were used to evaluate copy number
