The influence of different pressures of CO2 and the addition of caprylic acid methyl ester as an entrainer was studied for the extraction process of borage seed. The increase of CO2 pressure from 100 to 350 bar resulted in the increase in extract yield from 0.14 to 24.29% (w/w) while the changes in the extract composition were not so considerable. The highest solubility of pure caprylic acid methy
In the late nineteenth and for much of the twentieth century, an academic career in Sweden was highly dependent on what grade a scholar’s doctoral dissertation was awarded. Unless receiving a so-called “docent grade”, basically declaring the scholar eligible for seeking the title of docent (associate professor), the prospects of maintaining an academic career were bleak. Throughout the period, thiIn the late nineteenth and for much of the twentieth century, an academic career in Sweden was highly dependent on what grade a scholar’s doctoral dissertation was awarded. Unless receiving a so-called “docent grade”, basically declaring the scholar eligible for seeking the title of docent (associate professor), the prospects of maintaining an academic career were bleak. Throughout the period, thi
The ultrafast energy transfer among the pigments of the B800-850 membrane antenna pigment-protein complex of the photosynthetic purple bacteria Rhodobacter sphaeroides and Rhodopseudomonas palustris LL has been studied with ≈ 100 fs tunable infrared pulses at room temperature and 77 K. It is shown that the B800→B850 transfer time is similar in both species and occurs with a characteristic time con

The UN has defined 17 sustainable development goals in its 2030 Agenda for Sustainable Development. For almost every goal, a sustainable use of water and water resources are needed for achieving the goal. But what is sustainability? What are the most important challenges?
Popular Abstract in Swedish Akrylatallergi Plastmaterial består av stora molekyler som kallas polymerer samt tillsatsämnen som tillsätts för att modifiera materialets egenskaper. Polymerer bildas när det sker en stegvis reaktion mellan monomerer så att större molekyler bildas. Allergiframkallande ämnen i plastsystem kan vara monomererna, härdarna, modifierarna eller andra tillsatsämnen. AkrylaterAcrylate contact allergy has been frequently reported since the 1970s, with hundreds of articles published in dermatology journals so far. The purpose of this thesis was to investigate the frequency of contact allergy to acrylates / methacrylates in patients with exposure to industrial, dental and nail uses of these substances. We also aimed to investigate the clinical and chemical aspects of pa
Background and aims: “It’s best to start with air” states the current guidelines on the resuscitation of babies at birth. In a piglet model mimicking severe neonatal asphyxia and circulatory arrest, different aspects of resuscitation were investigated (studies I-III). The hypotheses were that the return of spontaneous circulation (ROSC) would occur faster with the use of oxygen (I and III) or adre
Denna uppsats syftar till att utreda gällande rätt kring det offentliga biträdets roll i LVU-processen. Framställningen görs ur ett barnrättsperspektiv med ändamålet att utreda huruvida processen i LVU-mål är likställd mellan å ena sidan socialnämnden, å andra sidan den unge och dennes vårdnadshavare. För detta syfte förekommer även inslag av ett komparativt perspektiv samt ett utvecklingsperspektThis thesis seeks to investigate applicable law concerning the public counsel in the process according to The Care of Young Persons (Special Provisions) Act (LVU). The thesis is written from a children’s rights perspective with the purpose of investigating whether the process is equal between the social welfare committee on the one hand, and the child on the other. When the social service needs
New data shows that there is genetic continuity between the Scandinavian Mesolithic Ertebølle culture and the Scandinavian Neolithic Pitted Ware culture. To examine whether it is possible to demonstrate the continuity in other aspects than the genetic, this paper examines graves from three Mesolithic grave fields (Skateholm I & II and Vedbæk) and two Neolithic grave fields (Ajvide and Västerbj
Since 1999, the World Bank (WB) and the International Monetary Fund (IMF) encourage developing countries to prepare the so called poverty reduction strategies (PRSs), which are national integrated strategies formulated through a participatory process coordinated with donors. This research has aimed to contribute to the development of effective PRS, especially the Sustainable Development and Povert
Solar cells based on conjugated polymer and fullerene blends have been developed as a low-cost alternative to silicon. For efficient solar cells, electron-hole pairs must separate into free mobile charges that can be extracted in high yield. We still lack good understanding of how, why and when carriers separate against the Coulomb attraction. Here we visualize the charge separation process in bul
I denna uppsats undersöks rättsläget för arbetstagares yttrandefrihet och gränserna för kritikrätten vid användning av sociala medier såsom Facebook och bloggar. Arbetstagaren har en plikt att vara lojal gentemot sin arbetsgivare. Lojalitetsplikten utgör en samlingsbeteckning för en rad olika förpliktelser, t.ex. tystnadsplikten och den närliggande skyldigheten att iaktta begränsning i kritikrätteIn this thesis the employees’ freedom of expression and right to criticize the employer when using social media such as Facebook and blogs is examined. The employee has an obligation to be loyal to his or her employer. The concept of loyalty covers many different obligations, for example the duty to respect confidentiality and the closely related duty to not criticize the employer, the employer’s
The purpose of this report was to bring together the subjects of innovation and social media to demonstrate that the potential of an innovation process in social media is huge and possibly underutilized, especially for Swedish small and medium-sized enterprises. The report provides an overview of innovation and social media. A literature review and a case study were conducted to examine how social
Examensarbetet utreder och diskuterar Lantmäteriets rapport om Stämpelskatt vid förvärv av fast egendom genom fastighetsbildningsåtgärder och hur deras förslag om en generell stämpelskatteplikt för förvärv av fast egendom genom fastighetsbildning kan se ut i olika situationer. För att förstå deras förslag görs en tillbakablick på utredning Vissa frågor inom fastighets- och stämpelskatteområdet, SOThis thesis investigates and discusses the National Land Survey of Sweden’s report “Stamp duty in acquisition of real property through property formation measures”, as well as their proposal for a general stamp duty liability for the acquisition of real property through property formation. To understand their proposal, a retrospective analysis has been conducted on the investigation “Certain Issu
Orbital or mean motion resonance (MMR) occurs when the orbital period ratio between two planets is close to a ratio of small integers. MMR can protect planets from collisions and affects the overall final architecture of the system. Observations of exoplanets have shown that the survival rate of MMR-chains is low, and most systems are near and just wide of an exact MMR. The most common chains are
Nature-based solutions (NbS) have proven effective in addressing urban sustainability challenges. This thesis focuses on bridging the gap in NbS short-term interventions, scale, and financial barriers. It examines the instrumentalization and implementation of successful long-term interventions from a policy and urban governance perspective, aiming to inspire cities and identify commonalities. The
This thesis is an explorative note on the non-Gaussian innovations of the volatility process. More specifically, the thesis investigates if the decomposition of the Standard Classical Laplace (SCL) distribution to a difference of two exponential is a valid alternative to modelling the asymmetric volatility processes, taking volatility clustering, the leverage effect and asymmetric response in vola
