Structural and mechanical alterations during hypertrophy of the rat portal vein were investigated. Growth of the vessel was induced by a partial ligature of the vessel causing an increased transmural pressure. Vessel segments from animals kept with ligature for 1, 3, 5 and 7 days, were compared with vessels from sham-operated animals. Maximal active force and vessel cross-sectional area increased
Propane ammoxidation to acrylonitrile over rutile-type vanadia catalysts is discussed regarding phase cooperation and site isolation effects. Compared with the pure phases, biphasic catalysts with both similar to SbVO4 and alpha -Sb2O4 are considerably more selective to the formation of acrylonitrile. It is demonstrated that cooperation between the phases during the calcination of the catalyst and
This volume of PERLES brings together two studies on bilingual acquisition of Romance languages. Both studies focus in different ways on the age of onset as a factor for development and subsequent mastery of a second language. In the past, the age of onset or the age factor has been studied from a variety of perspectives and often in connection with the Critical Period Hypothesis (CPH) (for a rece
This dissertation concerns an agricultural development project in Zambia, carried out by the Japanese NGO Shumei International, and MBAWOFA, a Zambian women's cooperative. The project teaches the Shumei agricultural technique “Natural Agriculture”, an organic farming method. The purpose of the dissertation is to study the MBAWOFA-Shumei cooperation and evaluate to what extent, and to what effe
Sweden was one of the most popular countries where many non-European students chose as the destination to study. However, since the introduction of tuition fees in the autumn of 2011, there has been a major reduction of enrolment in the total number of non-European students. Approximately all Swedish universities had a 33% decrease in the number of foreign students in 2011. However, Lund Universit
The trope solution to the problem of mental causation combines a trope monism, i.e. that properties are tropes and all tropes are physical, with a type dualism, i.e. that although all tropes are of a physical type, there are subsets of tropes that are also of a mental type. It does so in order to reconcile three individually plausible yet seemingly incompatible principles that together would ensur
Aquaculture is a growing sector and many studies are carried out to select and optimize species for conservation, keeping or production. Lately, new species are being introduced in aquaculture, although for some of them the basic knowledge is still incomplete. Moreover, there are further issues connected to acclimatising the new species to artificial conditions and have them reproduce successfully
This study explores the contexts in which the conflict evolved and how history was perceived, narrated and used by institutions, communities and individuals who sought to influence public opinion and policymakers. The theoretical point of departure is the concept of collective memory, defined as the totality of discourses through which a society makes sense of itself, the present and the future th
Science fiction is a genre in which anything is possible. It therefore comprises the perfect litmus test of any given culture’s prevailing hopes and fears about the future. One such source of anxiety that has been particularly conspicuous in works of fiction since the Industrial Revolution is the development of automata and other machines – specifically, whether they might eventually become strong
Ida Mexnell Ett biobränsles påverkan på luftmiljön Användningen av fossila bränslen anses i dagsläget vara den enskilt största orsaken till den globala uppvärmningen, vilket beror på dess bidrag till ökningen av växthusgaser i atmosfären. Med hopp om att kunna bromsa den uppvärmande trenden pågår forskning för att ta fram alternativa bränslen som ska vara mer skonsamma mot miljön och inte bidra Renewable alternatives to fossil fuels are of importance nowadays since the use of fossil fuels is considered to stand for the largest contribution to global warming. In recent years, a group of cyclic ethers called furans have been proposed as potential renewable fuels. To enable evaluation of the usefulness of these compounds as fuels, it is important to understand their atmospheric chemistry si
In an increasing number of Organizations for Economic Co-operation and Development (OECD) countries, the quality of hospital care has been subject to various forms of health policies. Despite much research on the determinants of health care quality, there is no consensus on the underlying factors of health care quality. This thesis contributes to the previous works by analyzing the relationship be
In October 1989, a 24-year-old Kurdish immigrant from Iraq was brought before the Sandviken Lower Court in Sweden charged with assaulting, coercing and threatening his pregnant ex-girlfriend who had left him to live with another man. Although, the court found the defendant guilty as charged, it nevertheless released him on a suspended sentence and a fine of 3000 Swedish Kronor. Conviction on this
In recent years it has become increasingly clear that chemical interactions play a fundamental role in aquatic habitats and have far-reaching evolutionary and ecological consequences. A plethora of studies have shown that aquatic organisms from most taxa and functional groups respond to minute concentrations of chemical substances released by other organisms. However, our knowledge of this “chemic
Migration of leukocytes from the circulating blood into the extravascular tissue is a key component in inflammatory reactions. Leukocyte extravasation (rolling-activation-adhesion-transmigration) is strictly coordinated by adhesion molecules and chemokines expressed on cell surfaces and in tissues. Tumor necrosis factor-alpha (TNF-alpha) is pleiotrophic cytokine, which plays an important role in t
I am concerned with Mary Wollstonecraft’s political morality. In it she makes no moral room, I claim, for emotional responses or emotional reasons for action, and it is important that she doesn’t. I will start by pointing at reasons for why it is important. I will then go on to analyse the content of and relations between her main political concepts: the triad of liberty, equality and virtue, with
In this article, I apply René Girard's theory of generative violence to the international law relating to the use of force. I argue that texts of international law make gestures of referral towards an immanent normativity on the fettering of divine violence. The means to this end is a form of sacrificial violence that seeks to promote the preservation and cohesion of the ‘international community’.
