Some major challenges in the development of L2L products is the lack of efficient converter electronics, modelling tools for dimensioning and furthermore, characterization facilities to support the successful development of the products. We report the development of 2 Three-Port-Converters respectively for 1-10Wp and 10-50 Wp with a peak efficiency of 97% at 1.8 W of PV power for the 10 Wp version

BACKGROUND: Intraabdominal and retroperitoneal sarcomas (IaRS) are malignant connective tissue tumors. Surgical resection is often the only curative treatment. The primary objective was to report the mid-term outcomes following contemporary treatment protocols and identify prognostic factors.METHODS: A retrospective review of consecutive patients (n = 107) with IaRS treated at single center from 2

Avhandlingen närmar sig frågan om hur journalistiska praktiker underlättar konstruktionen av kändisstatus. Teoretiskt uppfattas kändisskap som en särskilt flytande form av social status baserat på medierad uppmärksamhet och engagemang. Journalistik studeras som en invitation att dela upplevelser, organiserade utifrån narrativa strukturer. De empiriska fallen som studeras i avhandlingen är två mångThe thesis approaches the research question of how journalistic practices facilitate the construction of celebrity status. Theoretically, celebrity is conceptualised as a particularly fluid form of social status based on mediatized attention and engagement. Journalism is studied as an invitation to shareexperiences, organised through media logics and narrative structures. The empirical cases studi

In-situ quantification of particle concentration during the combustion of solid fuel powders is of importance for analyzing their combustion behaviors. Digital holography (DH) is applied here for studying iron powder combustion at high concentration. The performance of DH as a function of particle concentration is thoroughly studied with synthetic holograms. The detection efficiency is found to be

Residues 136-159 of VPI of foot and mouth disease virus (FMDV) comprise the G-H loop of the protein and form a prominent feature on the surface of virus particles. This sequence contains an immunodominant neutralizing epitope, which can be mimicked with synthetic peptides, and includes an Arg, Gly, Asp motif which has been implicated in the binding of the virus to cellular receptors. Crystallograp

Negative trends of climate change and biodiversity loss are closely linked with farming practices, and it is therefore essential to re-think how agricultural systems can sequester more carbon, and simultaneously create vital ecosystems. The overall aim of this research is to imagine Swedish farms as carbon sinks rather than sources, and how to re-design the current farm- and food system to also ad

This chapter explores the use of Experience Sampling Method (ESM) in a qualitative research design, departing from reflections on ontological and epistemological aspects of the tourist experience. It suggests that the tourist experience can be studied in its ordinary moments and proposes the use of ESM to capture such experience of “everydayness”. The chapter illustrates how the method can be used

The dawn of the COVID-19 pandemic in 2020 brought on an acceleration of the transition to virtual spaces in international diplomacy. Studying the virtualization of peace mediation, we describe the new conditions of hybrid peace mediation and show both advantages and challenges in comparison to traditional diplomatic face-to-face meetings. We show how virtual meetings have advantages, such as poten

The paper explores tourists’ smartphone-related information behavior on site in light of the concept of “planned serendipity”. The ability to gatherinformation at anytime and anywhere can deeply influence tourists’ behavior,their information needs and the outcomes of their travel plans. In this study, theconcept of planned serendipity is used to suggest that the outcome of travelinformation behavi

Smartphones have become one of the main tools for travel information search, especially on site, during the trip. The use of mobile technologies and ubiquitous internet connectivity do not only allow tourists to access information anywhere, at any time, but have deep impacts on tourists’ behaviours and on their whole tourist experience.The study suggests an interpretation of tourists’ information

Ribonucleotide reductase (RNR) is an essential enzyme that catalyzes the synthesis of DNA building blocks in virtually all living cells. NrdR, an RNR-specific repressor, controls the transcription of RNR genes and, often, its own, in most bacteria and some archaea. NrdR senses the concentration of nucleotides through its ATP-cone, an evolutionarily mobile domain that also regulates the enzymatic a

SQSTM1/p62 is an autophagic receptor that plays a major role in mediating stress and innate immune responses. Preclinical studies identified p62 as a target of the prototype innate defense regulator (IDR); however, the molecular mechanism of this process remains unclear. Here, we describe the structural basis and biological consequences of the interaction of p62 with the next generation of IDRs, d

Background: Survivors of childhood cancer can develop adverse health events later in life. Infrequent occurrences and scarcity of structured information result in analytical and statistical challenges. Alternative statistical approaches are required to investigate the basis of late effects in smaller data sets.Methods: Here we describe sex-specific health care use, mortality and causal association

As smart and as stupid, as well- and ill-informed, as curious and closed-minded as any random sample, tourists represent a unique object of study, as they are “the last remaining class that exhibits consciousness for itself” (MacCannell, 2013 p.xix). Technology has been transforming the tourist experience deeply, as it both fulfils a functional purpose of performing tasks for humans, and it holds

T lymphocyte acute lymphoblastic leukemia (T-ALL) is a heterogeneous disease affecting T cells at multiple stages of their development and is characterized by frequent genomic alterations. The transcription factor LEF1 is inactivated through mutation in a subset of T-ALL cases but elevated LEF1 expression and activating mutations have also been identified in this disease. Here we show, in a murine
