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

During March 2020 a large-span arena, Tarfalahallen, collapsed. The main load-bearing girders with a 54 m span were high and slender glulam trussed beams, supported from below by a cable system via vertical struts. Investigations concluded that the failure was initiated by out-of-plane buckling of the struts and slender beam, in spite of lateral stabilization by steel roof sheeting at the top edge

Objective: Antimuscarinic treatment in fasted mice and rats causes clonic convulsion soon after food intake. This study was designed to evaluate the electrophysiological markers of these convulsions and fasting in electrocorticograms in rats. Methods: Male Wistar albino rats were stereotaxically implanted with 10 cortical electrodes, and baseline electroencephalogram recordings were taken for 10 m

The legal empowerment approach is a recent attempt to be specific about the role of institutions for the eradication of poverty. This is a broad concept that includes not only the national formal judicial system in a country, but all formal and informal institutional structures providing the rules of the game of human interaction in any given society. The approach has invited a lot of debate as to

We present a new experimental method for the measurement of the compressibility of cells by analysis of free flow acoustophoresis separation data.

We report a new method to select the optimal actuation frequencies in bulk acoustophoresis devices, by means of differential impedance spectrum analysis measured via the actuating piezoelectric transducer (piezo). The impedance spectra is rich of large spurious resonance peaks originating from bulk resonances not related to the channel resonance, Fig. 1a, why direct measurement of the piezo impeda

The “neurotrophic hypothesis of depression” posits that low levels of brain-derived neurotrophic factor (BDNF) are associated with Major Depressive Disorder (MDD). Low levels of BDNF have also been found in individuals with suicide attempts, in MDD or other disorders, suggesting that low BDNF may also be associated with suicidality. We assessed serum BDNF in 68 physically healthy and unmedicated (

This work presents an acoustofluidic chip capable of separating cells form their corresponding secretome for subsequent MALDI-MS analysis, which can be used amongst many other applications for directed evolution.

We have studied a selection of factors influencing the damage of DNA in nanochannels during fluorescence imaging. For cutting and nicking of DNA we show that the DNA is shortened during imaging. To avoid photodamage over the course of several hours of a typical experiment, we demonstrate the importance of an oxygen free gas to propel the buffer solution through the device. Finally, by varying the

We show acoustic separation of 7.8 µm from 5 µm fluorescent polystyrene particles at an unprecedented sample flowrate of almost 1000 µL/min.

War has for a long time been fought at the expense of civilians. Depleted uranium has been one such object used in war that in the end would leave its mark on the civilian population and still today is the subject of discussions regarding its use. By using just war theory I will evaluate the American and British use of depleted uranium against the civilian populations of Iraq and former Yugoslavia

Publicerade våldtäktsanklagelser på sociala medier och ett icke-involverat rättsväsende blev karaktäriserande fenomen för Me Too-Rörelsen. Exemplifierat genom två huvudexempel hävdas avsaknaden av judiciell inblandning innebära ett ifrågasättande av antagandet att lagen styr staten, vilket i förlängningen argumenteras utgöra avsteg från Rättsstatsprincipen. Rättsstatsprincipen framhålls som grundPublishing rape allegations on social media whilst not involving the administration of justice became a significant phenomenon in the wake of the Me Too-Movement. Exemplified through two prime examples, the judicial un-involvement, arguably a questioning of the assumption that the law is the powerholder in the state, will be claimed to have been a departure from the concept of the Rule of Law. T

Den här studien handlar om körsång och dess potentiella påverkan på människor. Syftet är att ta reda på om – och hur körsångarna i Sinnesrokören upplever att körsången påverkar dem och vilka faktorer det är som gör att de i sådana fall påverkas. Körledarens drivkrafter och mål och hur dessa visar sig i praktiken undersöks också. Studien har en kvalitativ ansats och metoderna som använts är intervjThis study is about choir singing and its potential influence on people. The purpose is to find out if - and how the singers in the Serenitychoir experience that the choir singing affects them, and what factors matter when it comes to forming the experience. The choir conductor’s intentions and goals and how are transformed into practice are also investigated. The study has a qualitative approach

Antalet barnvräkningar har ökat stadigt år för år i Sverige. Detta trots att den svenska regeringen sedan långt tillbaka fastslagit en “nollvision” mot vräkningar av barn. FN:s barnrättskommitté har vid flertalet tillfällen rekommenderat Sverige att agera för att bättre följa sina internationella konventionsåtaganden, men de senaste åren av reformer och utredningar har inte haft någon effekt på anDespite efforts to turn the trend, the number of evictions of children have not decreased in Sweden. In fact, the number has steadily increased, despite the Swedish governments ”zero-vision” on child evictions. The CRC has on several occasions recommended Sweden to better conform with international law, but no clear improvement has been seen. This thesis investigates if the Swedish government has
