Visualizing the World. Epistemic Strategies in the History of Scientific Illustrations

The history of scientific illustrations is a story that correspond the cultural, economic, political and scientific history of the world. A look into the history of sciences displays that pictures and illustrations had a decisive role for the sciences progressive success and rising societal status from the sixteenth century. The illustrations visualized the unknown to graspable facts. Without the

Photosensitive copolymer of N-isopropylacrylamide and methacryloyl derivative of spyrobenzopyran

The copolymer of N-isopropylacrylamide (NIPAM) and methacryloyl derivative of spirobenzopyran (MSBP) with a molecular weight of 21 000 g/mol and the average molar MSBP content of 1.9% was prepared by free radical polymerization. The copolymer displayed its phase transition in water in the temperature range of 30-50 degreesC. UV irradiation of its aqueous solution caused photoinduced transformation

Small ice crystals and the climatology of lightning

[1] Vigorous debate still surrounds the cloud electrification process and unexplained regional variations in lightning activity. Here, we show that climatological maxima in lightning activity are associated with small effective diameter D-e of ice crystals near cumulonimbus cloud tops. This relationship, unlike lightning's more well-known relationship with cloud top height, is consistent over land

Mitigating Disorderly Leaving Events in G.fast

Vectoring is a vital component of wideband wire- line communication systems. A disorderly leaving event (DLE) disturbs the vectoring operation since the precoder, which was designed for the channel before the change, is no longer up to date. Measurements indicate that the impact of a DLE can be serious for frequencies beyond 30 MHz, which corresponds to the band used by emerging wideband communica

SWEDEN: Integrated strategies to overcome market barriers.

A national debate about how to transform and to ‘green’ the problematic housing stocks from the boom era has been going on since the late 1990s. Different kinds of policy instruments with energy efficiency objectives that address either energy systems, energy sources or construction and renovation of the building envelope have been in use. Some policy instruments have combined green objectives wit

GLI1-dependent transcriptional repression of CYLD in basal cell carcinoma

CYLD is a deubiquitination enzyme that regulates different cellular processes, such as cell proliferation and cell survival. Mutation and loss of heterozygosity of the CYLD gene causes development of cylindromatosis, a benign tumour originating from the skin. Our study shows that CYLD expression is dramatically downregulated in basal cell carcinoma (BCC), the most common cancer in humans. Reduced

Adsorption of Intact Cubic Liquid Crystalline Nanoparticles on Hydrophilic Surfaces: Lateral Organization, Interfacial Stability, Layer Structure, and Interaction Mechanism

Liquid crystalline cubic phase nanoparticles (known as Cubosome), based on glycerol monooleate and stabilized by a nonionic block copolymer (Pluronic F-127), adsorb intact on hydrophilic silica in the presence of an electrolyte, except at high pH. To characterize the nature of the interaction, four techniques were applied in situ: fluorescence microscopy, quartz crystal microbalance with dissipati

En gangster kunde kanske älska sin mor : Produktionen av moraliska klichéer i amerikanska polis- och deckarserier

Popular AbstractI denna studie står de brottslingar som befolkar amerikanska polis- och deckarserier i fokus. Två huvudgrupper urskiljs: De som begår brott på grund av de omständigheter de befinner sig i och de där brottsligheten framställs som en inre egenskap. I de olika avsnitten skildras hur de senare fördöms och exkluderas från den samhälleliga gemenskapen medan de förra förlåts för sin brottIn this study, American police- and detective-series are analysed. I focus on the portrayal of the criminals, especially the moral aspect. The series can be regarded as moral tales. The morality is embedded in the characters that populate the different episodes. There are two major categories of criminals in the series; the essentialized criminals and the ones that commit crimes due to circumstanc

Laser-induced fluorescence used in localizing atherosclerotic lesions

We have investigated laser-induced fluorescence frompost mortem human arteries in order to find spectroscopic properties allowing discrimination between normal and atherosclerotic vessel wall. A pulsed nitrogen laser emitting light at a wavelength of 337.1 nm was used as an excitation source. The fluorescence spectrum from 370 to 700 nm was captured and analysed by an optical multichannel analyser

Exploring the Railway System from a Risk Governance Perspective

Popular Abstract in Swedish Olyckor i järnvägssektorn kan ge upphov till katastrofala konsekvenser. I första hand kan människors liv och hälsa drabbas, men allvarliga konsekvenser kan även uppstå för samhället i stort. Detta beror på att järnvägssystemet, liksom en rad andra infrastruktursystem är väsentliga för att vårt moderna samhälle ska fungera. Under de senaste decennierna har dessa system bIn recent decades, the Swedish railway system has faced substantial deregulations. As a result, management of risk is often carried out in settings involving multiple stakeholders having various roles, mandates, and viewpoints on risk, and where no single stakeholder has the superior authority. In order to manage risks in this type of multi-actor setting, the traditional elements of risk assessmen

Experimental Investigations of Heat Transfer in a Channel with Ribs and Obstacle

Popular Abstract in English This thesis concerns experiments of heat transfer in a rectangular channel with ribs and an obstacle. Liquid crystal thermography (LCT) is used to record the temperature fields in the experiments. LCT is based on measurement of the color response of a heated surface. When illuminated with a white light, the liquid crystals react to temperature changes by changing color,This thesis presents experimental investigations of local heat transfer in a rectangular channel (aspect ratio AR = 4) with continuous transverse ribs as well as an obstacle. Liquid crystal thermography (LCT) is employed to obtain the temperature fields in the heat transfer experiments. The liquid crystal applied here has a red start at 35°C and a bandwidth of 1°C. The work consists of (1) periodi

Structuring uncertainty: sponsoring innovation and creativity

Dynamic and complex decision-making environments may involve high levels of uncertainty. Such uncertainty may lead to difficulty within decision-making processes. High levels of uncertainty in decision-making occur in a dynamic and complex environment. While decision-making is needed as a response to uncertainty, this may lead to difficulty within decision-making processes. Furthermore, there are

Accounting and auditing in municipal organisations – Four papers on accounting compliance and audit costs

This thesis is a quantitative study of accounting compliance and audit costs in Swedish municipal organisations, consisting of four papers. Three of the papers explore factors that explain accounting compliance concerning financial reporting and revenue recognition in Swedish municipal water, sewerage and solid waste management organisations. The fourth paper explores the determinants of professio

Post-processing removal of non-real characteristic modes via basis function perturbation

For more than 30 years since it was first proposed by Harrington et al., the Theory of Characteristic Mode (TCM) has only been applied to perfect electric conductors (PEC), and more recently lossless dielectric materials. One key challenge in computing the characteristic modes (CMs) of non-PEC materials using the PMCHWT surface integral equation is the presence of internal resonances in the soluti

Joseph Beuys : fett och filt : en forskningskritisk essä

Joseph Beuys. Fat and felt. A critical essay. The extremely singular materials fat and felt for use in art, have an entirely dominating role in a long series of Joseph Beuys’ (1921-1986) most important work. They are found both in single works of art as well as in installations and happenings from the beginning of the 1960s and up to the end of the artist’s life. This essay deals with the artist’

Nanophotonic-Enhanced Two-Photon-Excited Photoluminescence of Perovskite Quantum Dots

All-inorganic CsPbBr3 perovskite colloidal quantum dots have recently emerged as a promising material for a variety of optoelectronic applications, among others for multiphoton-pumped lasing. Nevertheless, high irradiance levels are generally required for such multiphoton processes. One strategy to enhance the multiphoton absorption is taking advantage of high local light intensities using photoni
