ABSTRACT— A model is described in which transient ischemia is induced in rats anaesthetized with N2O:O2 (70:30) by bilateral carotid artery clamping combined with a lowering of mean arterial blood pressure to 50 mm Hg, the latter being achieved by bleeding, or by bleeding supplemented with administration of trimetaphan or phentolamine. By the use of intubation, muscle paralysis with suxamethonium

The present study aimed to study the relation between the release of arachidonic acid (AA) and the energy state in cerebral cortices of rats during single episodes of cortical spreading depression (CSD). The changes in concentrations of AA, labile phosphate compounds [ATP, ADP, AMP, and phosphocreatine (PCr)], and glycolytic metabolites (lactate, pyruvate, glucose, and glycogen) were studied durin

Cooperation over shared water resources is often emphasised as something desirable. At the same time research show how a collaborative discourse can hide harmful effects of cooperation. Thus, the aim of this study is to show how water cooperation is problematized within the Nile Basin Cooperative Framework Agreement and the effects of this in the form of political implications. This is done with a

Artificial Intelligence (AI) is advancing rapidly. It is beginning to appear in personal life, business sectors, society, and shows impacts on each these contexts. The purpose of this study is to increase our understanding of how narrow AI could potentially affect the way we will organise. To fulfil this purpose, the Four Frames was used to collect and analyse recent publications for insights over

The general theory of international trade points out that the economic growth of a country will be significantly affected by global economic fluctuation if this country shows an increased dependence on foreign countries in the economic field. After the Chinese government adopted reform and opening up policy in 1978, many exciting changes could be seen in this country. Now, although China is still

Abstract In this thesis I will discuss the relationship between the European Union and the regions of Europe. The development of the European Union has meant that many decisions are taken in Bruxelles. Many actors participate in the policyprocess ranging from national goverment to policynetworks of different kinds. An emerging actor has been the regions of Europe. Their influence on the policypro

The essay discusses underlying racism in the Swedish community and has, as a specific purpose, to illustrate and analyze how images of immigrants are constructed in a local setting. The questions at issue are: What established conceptions about racism exist and how are immigrants described by the youth in Sweden? Which racist manifestations are evident? To answer these questions, twelve interviews

The formation of ESDP (European Security and Defense Policy) is one of the most important building blocks shaping the European security structure and the European integration process since the beginning of the 21st century. Even though the integration engine was injured by the rejection of the European Constitutional Treaty in France and the Netherlands, the ESDP can be seen as currently one of th

Cosmopolitanism is a widely acknowledged theory in the academic debate of global political theory and what this thesis aims to do is, is conducting an idea critique on this political theory of cosmopolitanism. The analysis is divided into two main parts where one is a reconstruction and one is a critical discussion. The reconstruction is based on four analytical dimensions: the temporal dimension,

Elevators has for a long period of time been regarded as unsafe to use as a means of egress. This is an opinion that has shifted in the last couple of years as technical solutions has been found to the initial problems when using elevators as an escape route. This report investigates the possibility to replace a staircase with emergency elevators as a means of egress in a buildning. The report als

Svensson (1997) föreslår att centralbanker på grund av implementerings- och utvärderingssvårigheter hos inflationsmål även bör ha ett mål för inflationsprognoser. Han argumenterar för detta med hjälp av en teoretisk modell som antar att den korta räntan, som centralbanken kontrollerar, påverkar BNP-gapet med en periods fördröjning, vilket sedan påverkar inflationen efter ännu en period. För att ma

Bosnia, a country torn by war in the 1990s, has yet not experienced reconciliation. Fifteen years after the war, fears are mounting, that Bosnia is again teetering toward crisis. This paper explores an under-studied factor in reconciliation – the meaning of the city. The analysis is carried out and inspired by Scott. A. Bollens theoretical framework, arguing that cities are physically, socially, p

Enzymatic pretreatment of algae by means of cellulose degrading enzyme was evaluated through lab-scale and pilot-scale experiments. The degradation efficiency of the enzyme depended on the initial physical quality of the algae. Lab-scale batch anaerobic digestion experiments showed comparatively low methane potential for the pretreated algae at both mesophilic and thermophilic temperatures. Howeve

Effects of hydrogen bonding and the axial ligand interaction on the B800 band in two LH2 complexes Rhodopseudomonas (Rps.) acidophila and Rhodospirillum (Rs.) molischianum have been theo retically investigated by using density functional theory. The local electrostatic environment of the B800 bacteriochlorophyll is simulated as an atomic charge field consisting of the pigments in the protomer unit

We present an analytical algorithm for deriving the shapes of the deformable mirrors to be used for multiconjugate adaptive correction on a large telescope. The algorithm is optimal in the limit where the overlap of the wave-front contributions from relevant atmospheric layers probed by the guide stars is close to the size of the pupil. The fundamental principle for correction is based on a minimi

Desertification, climate variability and food security are closely linked through drought, land cover changes, and climate and biological feedbacks. In Ghana, only few studies have documented these linkages. To establish this link the study provides historical and predicted climatic changes for two drought sensitive agro-ecological zones in Ghana and further determines how these changes have influ

In generally, there is a phenomenon of “free rider” in the establishment of national oil reserves for different countries, which means that they have the tendency of underestimating the strategic oil reserves. This paper attempts to explain this phenomenon from the perspective of non-cooperative game theory. It also analyzes the establishment of strategic oil reserve among different countries base

Utifrån aktuell forskning kring publik och reception, och mot bakgrund av en förskjutning inom samtidens scenkonst mot åskådarnas delaktighet och medansvar söker texten uppvärdera publiken och de många aspekter av teaterhändelsen som receptionsperspektivet aktualiserar, och bidra till en omdefiniering av teaterns problem och dess uppdrag visavi publiken.
