This paper demonstrates that vacuum impregnation of mature apple tissue in the presence of different sugars results in the formation of membrane vesicles inside the cells. Vesiculation is regarded to be a metabolic consequence of the impregnation process. Vesiculation is shown when the endocytic marker FM4-64 was impregnated into the apple tissue together with the sugar solutions. Vesicles were fo
As part of the LBA-SMOCC (Large-Scale Biosphere-Atmosphere Experiment in Amazonia – Smoke, Aerosols, Clouds, Rainfall, and Climate) 2002 campaign, we studied the emission of carbon monoxide (CO), carbon dioxide (CO2), and aerosol particles from Amazonian deforestation fires using an instrumented aircraft. Emission ratios for aerosol number (CN) relative to CO (ERCN/CO) fell in the range 14–32 cm−3
Background: Becoming critical ill or severely injured leads to a process of worry, anxiety and pain. Patients in intensive care sometimes have strange and frightening experiences and may show symptoms of acute confusion or delirium. CAM-ICU, the confusion assessment method for the intensive care unit, was based on the DSM IV, the Diagnostic and Statistic Manual of Mental Disorders IV, and today, h
Popular Abstract in Swedish När vi ser oss omkring i naturen är det lätt att överväldigas av den otroliga variationen i olika former, färger och mönster som förekommer. Var kommer all denna variation ifrån? Samma fråga ställde sig Charles Darwin för mer än 150 år sedan – svaret publicerade han 1859 i sin bok ”Om arternas uppkomst”. Evolution är den process som genom selektion gynnar vissa egenskapOur knowledge of the evolutionary potential of traits involved in different selective episodes, especially in natural populations, is still limited. This is true for questions such as the genetic basis and inheritance of traits, how natural and sexual selection acts on them, and how selective conflicts influence the evolutionary response to selection. In my thesis, I investigate these questions, u
This paper draws attention to a hitherto almost completely neglected encyclopaedic medical handbook composed around 950 CE: al-Muʿālajāt al-Buqrāṭiyya (Hippocratic treatment) attributed to the physician Abū al-Ḥasan Aḥmad b. Muḥammad aṭ-Ṭabarī. The handbook consists of ten books further divided into altogether 473 chapters. Since 1990, the work is available as a facsimile-print published by Sezgin
Popular Abstract in Swedish De senetruskiska votivhuvudena i terrakotta (bränd lera) från Tessennano på Medelhavsmuseet i Stockholm hittades 1956 i anslutning till en lantlig helgedom, ungefär tio mil norr om Rom, Italien. Att de är votivgåvor innebär att de skänktes av tillbedjare som representationer av dem själva inför gudomen eller gudomarna. Avhandlingen diskuterar emellertid inte de religiösThe Late etruscan terracotta votive heads from Tessennano were found near a rural sanctuary about a hundred km to the North of Rome in 1956. Whereas the facial fronts are serially produced with moulds, the backs are handmade. By using not only the moulded and the handmade features but the raw material (clay and temper) as well, it has been possible to make suggestions as to how, when and where the
Popular Abstract in Swedish Arbetet undersöker utvecklingar i romanen och novellen av författare som växte upp under New Order (1966-1998). Det är baserat på en survey av de båda genrerna, främst novellen som är tämligen omfattande. Avhandlingen övergår i en diskursanalys av form och innehåll som är relaterade till frågor ställda i inledningen, vilka rör förändringar och riktningar, och specifikt The work examines developments in the novel and the short story of writers who grew up during the New Order era (1966-1998) in the period of reform post 1998. It is assumed and subsequently affirmed that the genres are developing, modern genres in dialogue with the past and present. The work's main use of theory is that of M. M. Bakhtin's ideas of dialogism. The assumption of 'novelization' is fra
Heat exchanger network pinch sets the limitations of heat recovery for existing network topologies. Improving the heat recovery within a pinched-network is independent of the areas of individual exchangers present in the network, rather the topology of the network must be altered. Such a change in the topology can be very capital intensive and in many cases seems not easy to implement. This resear
Companies are constantly being pressured to innovate in order to stay competitive in the short run and have new offerings in the long run. One way of boosting innovation is to develop idea support systems that go beyond the traditional methods and tools. Through a qualitative study, this paper explores the lessons learned from developing an online platform for idea generation, and discusses it in
Popular Abstract in Swedish Denna doktorsavhandling i industridesign handlar om utmaningarna och möjligheterna att möta demografiska förskjutningarna och de förmodade förväntningarna hos dagens och morgondagens äldre generationer. Bakgrunden är avsaknaden av möbler som motsvarar efterfrågan hos äldre konsumenter och bristande kunskap om relationerna mellan möbler och äldre människor i hem- och vårThis thesis in industrial design concerns the challenges and possibilities in meeting demographic shifts and the presumed expectations of today’s and tomorrow’s older generations. The background is the lack of furniture that responds to the demands of older consumers and the lack of knowledge about relationships between people and furniture in their home environments and in various forms of elderl
This paper presents the design of a two-step process in which the first step is PEGylation of a protein, and the second step is chromatographic purification of the target mono-PEGylated protein from the unreacted and the di-PEGylated impurities. The difference between optimizing each process step separately and optimizing them simultaneously is studied. It was found that by optimizing the steps si
Internationalisation of higher education is a current theme in research and politics of higher education. The theme in this paper is related to present developments and concerns of the growing border-crossing activities that take place between nations and their systems of Higher Education. Higher education is expected to be grounded in research, research to be an international activity, and the un
Popular Abstract in Swedish Multikonjugerad Adaptiv Optik för Astronomiska Teleskop 1. Atmosfärisk turbulens Allt sedan man på 1600-talet började bruka optiska instrument inom astronomin, för att understödja det mänskliga ögat då man beskådade stjärnhimlen, har astronomer strävat efter att bygga allt större och bättre teleskop för att kunna se längre ut i rymden och skönja allt ljussvagare objekt.This work analyses several aspects of multi-conjugate adaptive optics (MCAO) for astronomy. The research ranges from fundamental and technical studies for present-day MCAO projects, to feasibility studies of high-order MCAO instruments for the extremely large telescopes (ELTs) of the future. The first part is an introductory exposition on atmospheric turbulence, adaptive optics (AO) and MCAO, esta
Most nuclear reactors, both in Sweden and worldwide, are enclosed by a prestressed concrete containment. The main purpose of the containment is to prevent any radioactive discharge to the environment in the event of a major internal accident. The performance and structural integrity of the containment depends on the compressive stresses induced in the concrete by the prestressing system. However,
The aim of this study in textile studies and cultural history is to gain a greater understanding of what happened to the division of labour and manufacturing techniques when female fashions changed in the period 1770-1830. This was a time of upheaval as regards fashions, and a change in dress practice. The decades around 1800 were a period of major societal and cultural transformation. Female fash
In this paper the design and demonstration of a 7 nm(3) h(-1) integrated steam reforming based hydrogen production unit using a Fischer-Tropsch diesel is reported. The system design is discussed in detail, including the fuel processor itself as well as the hydrogen purification and results from stand-alone operation of the combined unit operations is reported. Further, the results of an integratio
This thesis has contributed to the methodological development in the field of assistive technology and has generated new knowledge about the effectiveness and the service delivery process when powered mobility devices are provided to adult first time users in a Nordic context. Some of the results have been used to investigate the relationship between the three key elements of Donabedian’s conceptu
