Ett försök att designa metamorfa protein Ett centralt koncept inom biologi är att proteiner utför sina funktioner baserat på deras tredimensionella struktur. Vår förståelse kring faktorerna som styr vilken struktur ett protein får säger oss att ett protein antar den struktur som är energimässigt stabilast. Detta avgörs i sin tur av ordningen av proteinets aminosyror – dess ”byggstenar” – och hur
Vattenkraft är en omfattande nationell industri som förser Sverige med ungefär 45 % av dess energiproduktion (Molin 2016). Ett problem branschen brottas med är rödfärgade utfällningar som sätter igen mätinstrument och dränageledningar vid dammarna, så kallat. rödslam. Rödslammet produceras av järnoxiderande bakterier, FeOB, som oxiderar Fe(II) till Fe(III) (Hamrén 2013). Det partikulära järnet aHydropower is an extensive national industry which supplies Sweden with about 45 % of its total energy produced (Molin 2016). A problem which the industry is currently fighting is the presence of ochre-colored precipitations that clog vital measuring tools and drainage pipes at the dams, commonly called red mud. The red mud is produced by iron-oxidizing bacteria, FeOB, which oxidize Fe(II) to F
Produkter vi köper påverkar miljön under hela livscykeln, från produktion till omhändertagande av avfall. Flera studier har visat att en ökad användning av naturresurser är direkt förknippad med en ökad miljöpåverkan. En omställning till mer hållbara alternativ vore därför mer fördelaktigt för miljön. Ett alternativ för en mer hållbar konsumtion är återtillverkning. Återtillverkning är en process An increase in the use of natural resources is directly associated with an increased environmental impact. It is therefore of importance to lead the manufacturing industry towards a route of material efficiency. Remanufacturing is an industrial process that brings a used product and its components back to like-new or better condition. By avoiding manufacturing of new products, great savings in vir
Five Xantha-m chlorophyll-deficient mutants which are lethal after the seedling stage have been already discovered in barley (Hordeum vulgare L.) and a candidate gene, SecA1, was recently identified by Bulked segregant analysis (BSA). SecA1 protein participates in the stroma-to-lumen protein transfer across the thylakoid membrane. In this study, the Xantha-m gene was analyzed. Western blotting exp
It is commonly assumed that algorithmic curation of search results creates filter bubbles, where users’ beliefs are continually reinforced and opposing views are suppressed. However, empirical evidence has failed to support this hypothesis. Instead, we suggest that filter bubbles may result from individuals acting selectively on information made available by search engines. When presented with sea
Government and individual responses to the coronavirus disease 2019 (COVID-19) pandemic have had significant health and economic consequences. Governments imposed measures, including lockdowns, designed to suppress transmission and alleviate the burden on health systems, while private individuals exercised voluntary social distancing, compliance with government-imposed measures and exhibited incre
Purpose: This study aims to add and extend onto the existing studies regarding open innovation in SMEs but to tackle it from a neglected angle that is operating during times of uncertainty. Additionally, this study seeks to explore the mechanisms which SMEs use to reduce R&D budgets, increase the quality of innovations and continue the pace of innovations during the COVID-19 pandemic. Methodo
Utfärdande :De olika egenskaperna i distributionskedjan mellan fysiska affärer och E-handel har skapat ett potentiellt behov för en ny sorts paketering inom E-handel. Syfte : Syftet med studien är förstå varför det finns ett ökat behov av olika förpackningsalternativ på marknaden utifrån konsument, producent och online handelens perspektiv. Samarbetet med Tetra Pak syftar också till att analysera Issue of study : The difference in supply chain characteristics between brick and mortar and E-commerce has triggered the potential need of new packaging requirements for E-commerce. Purpose : The purpose of this study is to understand why there might be specific packaging requisites in the online channels and what the requirements are. The thesis aims to explore the product and the logistics requ
European policymakers are increasingly interested in encouraging and supporting social entrepreneurship. Addressing the goal, this thesis analyses the relationship between human capital and an individual’s propensity for social entrepreneurship in European countries. Additionally, it is investigated how institutional environment moderates this relationship. Utilising a dataset of the Global Entrep
Kommunal styrning av hållbara konsumtionsmönster på hushållsnivå Många svenska kommuner har antagit ambitiösa klimatmål, flera av dem försöker påverka sina invånares konsumtionsmönster, vilket är en av de största orsakerna till växthusgasutsläppen. Hur kan svenska kommuner påverka sina invånares konsumtionsvanor, när konsumtionsvalet trots allt ligger i deras händer? I denna studie jämförs hur tToday most Swedish municipalities work actively with climate change mitigation with the goal to decrease their total emissions of greenhouse gases. To achieve this, the municipalities must decrease their consumption related emissions. This is a rather new question within local governance, which begs the question, how do municipalities work to govern its citizens’ consumption patterns? This study s
Forskning visar att kvinnor känner ett större engagemang för klimatet, men också en större oro för klimatförändringar och dess konsekvenser. Tidigare forskning visar även att vita män som har en konservativ politisk orientering är de som är minst oroade för klimatförändringar. Syftet med detta kvalitativa arbete är att med hjälp av intervjuer skapa en förståelse för kvinnors upplevelse av klimatfö
Företag har genomfört stora förändringar efter att den svenska Folkhälsomyndigheten införde rekommendationer om hemarbete till följd av Covid-19 pandemin. Distansarbete har ökat kraftigt i omfattning och prognosen är att även efter pandemin kommer det flexibla arbetssättet kvarstå. Syftet med det här examensarbetet är att undersöka vilka eventuella utmaningar som distansarbete medför för framtidenCompanies have implemented major changes due to the recommendations of remote work introduced by the Swedish Public Health Agency as a result of the Covid-19 pandemic. Remote work has rapidly increased, and the forecast is that this flexible working method will remain. The purpose of this thesis is to examine which challenges remote work entails for offices in the future, and with this data presen
The purpose of this project was to investigate protein stabilization by formulation excipients during the process of freeze-drying using Molecular Dynamics (MD) simulation. A recombinant therapeutic protein, Reteplase, was used as a model and the study focused on a comparative analysis of two excipients, arginine and tranexamic acid (TXA), as included in commercially available formulations of Rete
Cross-national surveys have pointed out that environmental concern has been decreasing across the globe over time due to a focus on economic growth. While cultural and socio- demographic factors determine the degree of a lack of environmental concern, preference measures namely risk, patience, positive reciprocity, negative reciprocity, altruism and trust have found to be determinants as well. Thi
BUT A SURFACE is a product that offers a surface which helps users to switch between positions they like freely when working from home with devices like laptops. Under the COVID-19 pandemic, working from home has become a “new normal”. Compared with working in the office or school, people usually perform more relaxed in positions like sitting casually on lounge chairs or sofas when working from h
The project explores the harmful effects of excessive light exposure at night and people’s sleeping habits. Most people would use electronic devices in bed for a long time before sleep, and sometimes we fall asleep and accidentally leave the light on all night. And there are also some people who are afraid of darkness prefer to sleep with the light on all night. Sleeping with the light on delibe
The connection between general government debt levels and centralization of general government expenditure is compared in 31 countries 1995-2019 and 35 countries 1972-2019, with four country groups in each of the datasets analyzed further. Connections between centralization and changes in debt levels are found to be mostly insignificant and results unstable to the inclusion of lagged changes in de
