Controlling activity of defined populations of neurons without affecting other neurons in the brain is now possible by a new gene- and neuroengineering technology termed optogenetics. Derived from microbial organisms, opsin genes encoding light-activated ion channels and pumps (channelrhodopsin-2 [ChR2]; halorhodopsin [NpHR], respectively), engineered for expression in the mammalian brain, can be
Klimatförändringar är en ökande verklighet för många människor, sätter vår framtid på spel, och ställer krav på hur vi kan skapa förändring. Syftet med denna kvantitativa studie var att undersöka forskningsfrågan om natursyn påverkar individens miljövänligt beteende, samt replikerade tidigare forskning som visat att kvinnor tenderar att vara mer miljövänliga än män. En enkät bestående av 12 frågorClimate change is an increasing reality for many people, risking our future and demanding ways to mitigate the process. The purpose of this quantitative study was to investigate the research question regarding if perception of nature has an impact on pro-environmental behavior, as well as replicating previous research stating that women are prone to more pro-environmental behavior than men. An int
Since the legal reform and adoption of the new sex purchase act in 1999, the efficiency of governmental actions and continuance of social vulnerability among prostitutes/sex workers in Sweden have been recurring topics in public debate. Conflicting views on what the problem actually is and how it might best be dealt with, create a divide between those who advocate a liberal feminist perspective, a
Swedish migration politics is going through a radical change in 2016 when restrictive temporary laws are accompanied by governmental plans of deporting up to 80,000 people the coming year. This thesis takes a hold of these changes and investigates how the political ambition of deporting a radically increased amount of people has been made possible. More specifically, the thesis examines how the Sw
Electrical and electronic equipment (EEE) causes serious environmental impact in its end-of-life phase and it is the largest known source of heavy metals and organic pollutants in municipal waste. Moreover, waste electrical and electronic equipment (WEEE) containes valuable components that if recycled and reused, could reduce the use of virgin materials. However, nowdays WEEE is mostly landfilled.
Merger and acquisition deals are one of the most important events corporations engage in. After completing mergers the most essential task for executives would be maintaining joint revenue growth in order to provide the deal’s success. So, customers’ reaction to M&As is a crucial factor for the achievement of goals through M&A. The main purpose of this thesis is to study how customers reac
The particularities surrounding the way decentralized multinational companies are structured and governed can determine the success or failure of integrating sustainability aspects into their units’ approach of doing business. The choice of pursuing a decentralized avenue over a headquarter-driven one in managing sustainability can have a significant influence over the coherence of Group1-wide str
We have conducted this master thesis for Heatex AB, located in Trelleborg. The company is the market leading OEM supplier of air-to-air heat exchangers. In a more and more competitive market, the demands on the design and the preparation for manufacturing are increasing making integration an important factor. Our work comprises the company’s design and preparation for manufacturing of cooling unit
Land acquisitions have increased significantly over the last decade and claims have been made that these actions are both neo-colonial and wrong. Others claim that there are benefits to be gained for all parties, directly and indirectly involved. When land is being sold or leased from poor farmers to rich corporations what are the potentials and what are the limitations? Are livelihoods, displacem
A granny job with soft issues, feelings and stuff - A qualitative study of men in a female-dominated profession The purpose of this study was to examine how professional social workers and students in social work education relates to and understands the idea that social work is considered feminine. Another aspect considered in this study is how the widespread predominance of women in social work
The purpose of this thesis is to find a model, which is based on economic variables that can forecast the cotton price better than commonly used benchmark models. A vector error correction model is used because of the existence of non-stationary variables and one cointegration relation in the data. Two types of forecasting methods are used for out-of sample predictions. The dynamic forecasting in
Målet med projektet var att analysera problem med arbete i kyla i mjölkproduktionsanläggningar vad gäller förekomst, frekvens och skaderisk samt att föreslå åtgärder för förbättringar. Projektet bestod av två delar: Del 1. En fältstudie, som genomfördes dels i Uppsalatrakten, dels i Västerbottens län. Del 2. En enkätstudie, riktad till Lantbrukshälsans medlemmar i norra regionen. Fältstudierna omfThe aim of the project was to analyse problems with cold when working in dairyfarms with respect to prevalence, frequency and risk for injuries and to propose measures for improvements of thermal conditions. The project comprised two parts: a field study and a questionnaire survey. The field studies were performed at seven dairy-farms in the Uppsala region and six dairy-farms in the northern regio
The study of quark jets in e(+)e(-) reactions at LEP has demonstrated that the hadronisation process is reproduced well by the Lund string model. However. our understanding of gluon fragmentation is less complete. In this study enriched quark and gluon jet samples of different purities are selected in three-jet events from hadronic decays of the Z collected by the DELPHI experiment in the LEP runs
This report describes a language and an interactive environment, called LICS, for implementation of control systems and dynamic modelling. It used graphics for representation of the structural properties: hierarchical decomposition, interconnection structure, and structure of the interfaces. The decomposition and interconnection structures are described by block diagrams. Low level modules are des
Anaerobic degradation of a semi-solid waste with a total solids content of 4% particulate matter, much of it insoluble, was investigated in four laboratory-scale reactors. Two of the reactors were equipped with different textile materials for immobilisation of microorganisms, while the other two were used as continuously-stirred-tank reactor references, A constant organic loading rate and hydrauli
The oncogene cyclin D1 is highly expressed in many breast cancers and, despite its proliferation-activating properties, it has been linked to a less malignant phenotype. To clarify this observation, we focused on two key components of malignant behavior, migration and proliferation, and observed that quiescent G0/G1 cells display an increased migratory capacity compared to cycling cells. We also f
Sp1/Kruppel-like factor (KLF) family of transcription factors regulates diverse biological processes including cell growth, differentiation, and development through modulation of gene expression. This family of factors regulates transcription positively and negatively by binding to the GC and GT/CACCC boxes in the promoter through their highly conserved three zinc finger domains. Although the mole
The aeolian deposits of Sweden have received modest attention, despite their usefulness as a palaeoenvironmental archive. Here we present sedimentological information and optically stimulated luminescence (OSL) ages from inland sand dunes in the lowlands of south-central Sweden. Three main lithofacies, each with two subfacies, were identified in the deposits: massive sand, laminated sand and cross
Inconel 718 is a Ni-based superalloy that can perform excellently at elevated temperatures. However, surface and subsurface damages in the form of microstructural and property changes and tensile residual stresses are common in a machined Inconel 718 component because of its poor machinability. Such damages have a significant influence on performance and the life time of the part. To characterise Inconel 718 is a Ni-based superalloy that can perform excellently at elevated temperatures.
