- The Cherenkov Telescope Array (CTA) is a new observatory for very high-energy (VHE) gamma rays. CTA has ambitions science goals, for which it is necessary to achieve full-sky coverage, to improve the sensitivity by about an order of magnitude, to span about four decades of energy, from a few tens of GeV to above 100 TeV with enhanced angular and energy resolutions over existing VHE gamma-ray observatories. An international collaboration has formed with more than 1000 members from 27 countries in Europe, Asia, Africa and North and South America. In 2010 the CTA Consortium completed a Design Study and started a three-year Preparatory Phase which leads to production readiness of CTA in 2014. In this paper we introduce the science goals and the concept of CTA, and provide an overview of the project. (C) 2013 Elsevier B.V. All rights reserved.

GO-GN Conceptual Frameworks Guide
- 2021
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- If you’re a doctoral researcher (in any discipline) or someone who produces research in a professional capacity you’ve perhaps encountered the phrase “conceptual framework”. Sometimes a whole chapter of a Ph.D or Ed.D might be given over to investigating the relevance of different frameworks for an area of inquiry, or to synthesizing several frameworks together to ground the approach taken to answering a specific research question. Alternatively, you might not have heard much mention of conceptual frameworks or how they relate to what you are trying to achieve with your research. A conceptual framework brings together a set of ideas and articulates the different concepts that will be used in a study or research project. Because this is highly contextual - and often specific to a particular research question or approach - there aren’t really any general rules that cover how to do this. In addition, there is a lot of ambiguity and impreciseness in the language used to describe this stuff. Sometimes people talk about theoretical frameworks, or models, or a ‘theory of action’ that guides their research project. But do these mean different things? And are there differences between disciplines? In an empirical project the conceptual framework might be used to determine the kinds of questions to ask in a survey, or which data points to collect and focus on. A conceptual framework might be used to generate a hypothesis that is to be tested, or to facilitate the interpretation of results. On the qualitative side a conceptual framework might be used to provide the right kinds of descriptions at different stages of the research process; to identify or explore categories of analysis; or to guide and refine the conclusions drawn by a study. All of these things can happen in a single project! Given the importance and centrality of these frameworks, it might be surprising to learn that relatively little has been written about using them in research. There’s certainly a lot less published about this than research methods or methodology, for instance. (Though different methods often come with specific conceptual frameworks built in or with a more obvious alignment). So, to start making sense of all this we begin by looking at some of the papers that offer systematic guidance or understanding of the role of conceptual frameworks in research. As this guide progresses we’ll bring in perspectives from GO-GN members on their experiences with developing and using conceptual frameworks.

The small CAB-like proteins of the cyanobacterium Synechocystis sp. PCC 6803 : Transcriptomic, proteomic and metabolomic analyses reveal new insights into their function
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- The five small CAB-like proteins (ScpA-E) of the cyanobacterium Synechocystis sp. PCC 6803 consist of one transmembrane helix and belong to the light-harvesting like family. While in wild type they are induced by various stresses, in cells with Photosystem I (PSI) -less background the SCPs are constitutively expressed. Here we performed a detailed comparison of a PSI-less control strain with a strain depleted of PSI and all SCPs, with the aim to elucidate the function of the SCPs within Photosystem II. Electron microscopical immages showed a drastic alteration of the cellular organization, visible by a rough surface and few thylakoid membranes in the PSI-less/ScpABCDE- strain. Immunoblots pointed to a decreased amount of PSII per cell volume. Deletion of the scp genes also affected the carbon- and nitrogen-balance and thereby the carbohydrate accumulation at the expenses of protein- and chlorophyll-synthesis as judged by transcriptomic and metabolomic analyses. Our results show that SCPs ensure a correct assembly/repair of PSII and therefore are important for the adaptation to environmental stresses - especially during the generation of reactive oxygen species.
