Extraordinary transmission of electromagnetic power through sub-wavelength apertures is usually observed in a narrow bandwidth range and the transmission outside this range is low. In this paper, it is shown that the transmission through periodic apertures in an otherwise perfectly electric conducting sheet satisfies a sum rule that relates wavelength regions with transmission above a threshold wi

In human service organisations, evidence-based practice (EBP) implies that practice and decision-making should be guided by empirical evidence in a systematic way. Policy makers and researchers argue that practitioners in many fields do not apply state-of-the-art methods and that they should rely on evidence in a more systematic way. Among the suggested reasons for this state of affairs we note la

Species of the ascomycetous genus Cladobotryum (Hypocreales, Hypocreaceae) are ecologically and economically important mycoparasites that cause cobweb disease in cultivated and wild mushrooms. Despite their significance as fungal pathogens and producers of bioactive metabolites, the taxonomy of Cladobotryum remains unresolved due to extensive morphological plasticity, complex teleomorph–anamorph c

Crises narratives surrounding the societal challenges of biodiversity loss, climate change, and human health and well-being dominate current debates in global environmental politics. These challenges are deeply interconnected and require transformative and integrated change. Marine and coastal Nature-based Solutions (blue NbS) are an opportunity to minimise harmful human impacts on these ecosystem

The international financial crisis has hit southern European countries remarkably hard. As a consequence, governments have introduced economic austerity in order to cope with such a difficult situation. Perhaps most important, left-wing and right-wing parties have contributed to the implementation of these economic policies. Given this unexpected consensus, this thesis examines the Italian case st

What do current irregular migration flows in the Mediterranean Region, and subsequent policy responses in terms of migration and border control, tell us about the significance of the external borders of the EU in a context of globalization?

This master thesis is an attempt to approach the issue of the lack of application of cause advocacy in modern social work practice. The research problem is framed in a way that historical roots of the commitment to social justice in the profession are presented with the further argumentation for the lack of this approach in contemporary social work. A qualitative study has been conducted to fulfil

This research has been inspired by my interest in theater. I decided to explore the connection between the disciplines of media studies and anthropology of performance through the particular case study. The case is the Russian-Chinese pipeline construction through the sacred Ukok plateau in Altai. It threatens the environmental and cultural uniqueness of this area and small indigenous population o

The Egyptian Revolution of 2011 opened up the public space for Egyptian women from very different backgrounds. However, although women played a decisive role in revolutionary events, this did not result in the abolishment of the patriarchal bargain between Egyptian secular-oriented female feminists and the state in post-Mubarak Egypt. Even though certain conditions caused the suspension of the pat

Empowerment is a concept that is well-known and used within the development, but is also a concept that is highly contested within the field where there is no coherence in what empowerment really is and how it is achieved. The main purpose of this thesis is to look into the concept of empowerment and how the perception of it is inefficient in terms of the discourse existing within the paradigm. Th

Binära föreningar beståendes av sällsynta jordartsmetallerna och rutenium uppvisar intressanta egenskaper såsom superledande förmåga och intressanta magnetiska egenskaper. För att förstå varför vissa föreningar uppvisar sådana egenskaper är det essentiellt att studera föreningarnas kristallstruktur. I denna rapport undersöks föreningar, i 35-38 at. % Ru regionen, beståendes av praseodym, neodymiumBinary alloys comprising of the rare earth metals along with ruthenium, RE-Ru, have been noted to display superconductivity at low temperatures. Furthermore the alloys display interesting magnetic properties such as anomalies in magnetization measurements below the magnetic ordering temperature. In order to understand how some compounds obtain these intrinsic properties it is vital to investigate

After the failure to respond adequately to the changing patterns of conflict and violence after the end of the Cold War, human security was popularized in the 1990s as an alternative concept to security more suitable to face threats to individual security. Ever since, the question about what human security should entail has seen much discussion. This paper examines the different discourses which i

In Colombia, indigenous leaders and organizations claim that among the problems that indigenous youth face in relation to their participation in conventional higher education there is the potential loss of their indigenous identity and their acculturation (Muñoz 2007; ONIC, et al. 2004; Green et al. 2004). In the light of these claims, this thesis explores how indigenous students experience their

In recent years, several companies have emerged on the Swedish market offering insulation in the form of sprayed polyurethane foams. In order to determine their suitability under Swedish conditions there is the need for a thorough evaluation of these products. To help contractors assess the suitability of these materials, the declared product characteristics have been examined in relation to the S
