Högre verkningsgrader, stabilitet och minskad toxicitet; så skall framtidens solceller nå verkligheten. Många hoppas att solenergi ska ta över våra energibehov och varje dag närmar vi oss en grönare utvinning av elektricitet. Kommer våra bilar och byggnader täckas av solceller i framtiden? Inte helt omöjligt, om vi kan bemästra det fascinerande materialet perovskit. På EPFL, Ecóle Polytechnique FPerovskite research has quickly gone from non-existent to one of the biggest reseach areas in Photo- voltaics. There are still many questions to be solved regarding the stability, environmental impact, reproducible large area devices, efficiency and module fabrication cost of Perovskite Solar Cells, PSCs, before commercial up-scaling. Scientists all over the world are working towards solutions and

"Developmental Assets" refer to a series of relevant experiences, relationships, skills and values that can effectively promote the healthy development of children. They are social and psychological strengths that can enhance the healthy development of children and adolescents. Studies have shown that having sufficient developmental assets can develop children's competencies, skills

Background. Released mechanisms were investigated in Pickering emulsions stabilized by quinoa starch granules. Non-heat treated (NHT) and heat treated (HT) emulsions were studied for their stability and for their ability to efficiently encapsulate peptides and give controlled release after partially simulated in vitro intestinal digestion with release systems containing combinations of phosphate b

Recent studies have shown the discriminatory and patriarchal nature of personal status laws in Lebanon (Geagea et al. 2015; Mikdashi 2018b). Stories abound of women losing custody of their children due to laws that favor paternal custody and of couples pursuing civil marriages abroad to avoid being subject to religious courts in Lebanon (Abillama 2018). Literature on the subject has focused on the

Abstract Digital sourcing platforms were invented in the last decade of the 20th century and brought tools such as electronic reverse auctions (eRA) into the hands of purchasing professionals. The Trelleborg Group initiated a project to implement such a digital sourcing platform last year but the research in the field is outdated. Focus was directed to the choice of sourcing approach, i.e. either

This study compares the performance of equal- and value-weighted portfolios using a broad investment universe consisting of the stocks from the Swedish stock market. While implementing random sampling in the portfolio construction procedure, three rebalancing schemes are applied on the equally weighted portfolio in order to observe differences in performance among these. In order to compare how mu

IPO underpricing is an international phenomenon that has been documented by numerous authors. However, the IPO market keeps evolving. Since the decline in IPO volume following the “dot-com bubble”, there have been periods with high IPO volume, as well as periods with low IPO volume. This paper uses a linear regression model and t-tests to investigate underpricing of European IPOs between 2001 and

Wet cupping, or traditional Finnish cupping has been practised in Finland for several centuries. It is a treatment where blood is removed from the body through a ritual-like procedure. The treatment starts with the cupper making small cuts on the skin with a lancet or cuppers axe. Cups are placed over the cuts, and through the vacuum that emerge under the cups blood is drained. Still in the middle

This thesis aims to explore the workflow related to designing an application specific instruction-set processor (ASIP). An ASIP is a processor similar to a hardware accelerator (HAC) in terms of performance and efficiency, but containing elements of general purpose processors (GPPs) when it comes to programmability and flexibility. The thesis centers around the design of an ASIP which will handle

I denna studie har vi studerat de interna patienttransportörernas arbetsflöde och det förändringsarbete som finns inom lean. Vi har även belyst medarbetarnas värdeskapande och välmående i vårds- och arbetsmiljön. Arbetet utgår ifrån fallstudien om Malmö Universitetssjukhus och bygger på att skapa en förståelse över deras verksamhetsstyrning i interaktion med logistiken för att vidare kunna implemeIn this study, we have studied the internal patient transporters' workflow and the change work that exists within lean. We have also highlighted the employees' value creation and well-being in the care and work environment. The work is based on the case study of Malmö University Hospital and is based on creating an understanding of their business management in interaction with logistics in

The marginal pricing power and individual impact of proxies used in international asset pricing and financial integration studies is not well researched. In this study I look at the most widely used proxies; i.e. World Index Return, change in Eurodollar rate, change in spread between 10-year U.S. T-bond and 3-month U.S. T-bill, and change in spread between Baa and Aaa rated bonds; and ascertain wh

In archaeology, we face a unique situation where our primary research method is destructive; excavation as a recording method can only be conducted once. But with the introduction of modern 3D recording methods, much of the process of excavation can be saved and reused. But at the same time, we must overcome the difficulties of examining sites where the data recorded has been accumulated over vast

Sustainability communication is an emerging concept in communication practice and become organization matters in term of organizational communication and organizational legitimacy. This study is taking from a sustainability initiatives point of view on how the organization communicates their sustainability initiatives in order to gain legitimacy and stakeholder support, particularly through web-ba

The paradigm of of cloud computing have brought with it the challenge of vendor lock-in, preventing customers from choose from alternative vendors and induces substantial costs for switching provider. Since only a limited number of in-depth studies who investigate the complexity of cloud lock-in problem within enterprise organizations exist, this thesis tries to describe the measures taken by comp

Linc-DGCR6-1 as a new potential “bodyguard” of human germ cell survival Immune responses are essential to protect us from pathogens. However, there are distinct sites of our body, such as brain or testis, in which the action of systemic immune system is not well tolerated. For this reason, these sites evolved different strategies to suppress immune responses, creating what is known as “immune pri

Many premature deaths and health problems could be prevented by adhering to a healthy diet, however, many people lack the self-regulation needed for maintaining healthy behaviors. Goal-conflicting situations (i.e., when a person needs to decide between one of two conflicting goals) are an obstacle for self-regulation, while coping planning is found to be useful in these situations since it entails

Immune function is an important parameter in almost all organisms which determines their ability to survive and fight off pathogens. Immune function (like other physiological functions) is temperature dependent. So that opens the question of how immune function is in poikilotherms. Being poikilotherm means that the species depends on the ambient temperature for body heat regulation. I used crucian

Konsten att ”baka” fram en hjärnsjukdomsmodell Sjukdomar som påverkar hjärnan blir allt vanligare allt eftersom vi åldras och medellivslängden i världen ökar. Senilitet, som en gång i tiden ansågs vara en nästan oundviklig del av att bli gammal. Idag förstår vi att det har att göra med neurodegenerativa sjukdomar, som kan pågå i många år med stegvisa humörförändringar och små ändringar i beteendNeuronopathic Gaucher’s Disease is an early-onset neurological disorder with progressive dysfunction and degeneration of neuronal cells, caused by dysfunctions in the endosomal-autophagic-lysosomal pathway. A lysosomal enzyme deficiency results in accumulation of substrate and subsequent impairment of the lysosomes. While the cause is known, the disease mechanisms driving the neurodegeneration are

Many evidence supports the notion that protein aggregation in the brain leads to neurodegenerative diseases, characterized by progressive degeneration of neuron structure and function in the brain. Protein aggregation causes a variety of diseases such Alzheimer’s disease (AD) and Parkinson’s disease (PD). Generation of extracellular amyloid-beta (Ab) plaques and aggregation of α-synuclein (α-syn),Several studies suggest that protein aggregation in the brain leads to neurodegenera-tive diseases. Two examples of this are seen in the neuropathological hallmarks of Parkinson’s disease (PD) and Alzheimer’s disease (AD) in the form of a-synuclein (a-syn) and amyloid-beta (Ab) plaques, respectively. However, an overlap of these pa-thologies has been observed in more than 50% of AD cases. This res
