This report summarizes the advantages and disadvantages of organic and conventional farming from an environmental and sustainable perspective. A sustainable agriculture system needs to be able to meet a higher demand for food due to a growing population and minimize the damage of the environment at the same time. The main critic to the organic farming system is that it produces lower yields than
The main purpose of this report is to identify, evaluate and if possible, suggest reduction methods to the risks from which users at the beamline BALDER, MAX IV Laboratory are exposed to during their visit. Identified risks includes radiation, fire, electricity, gases and miscellaneous risks such as the overhead crane. The evaluation indicates that the handling of toxic gases inside the experiment
Anknytning mellan spädbarn och föräldrar är en naturlig process som sköter sig intuitivt och kan stödjas av BVC-sjuksköterskor. Syftet var att beskriva BVC-sjuksköterskors upplevelse av anknytning och gott samspel mellan spädbarn och deras föräldrar samt hur anknytningen kan stödjas. Tolv BVC-sjuksköterskor intervjuades och resultatet framställdes med hjälp av kvalitativ innehållsanalys. Det goda
The term 'Object Shift' means that a weak object pronoun has been raised to a position to the left of a sentence adverbial. In Swedish, there are mainly two positions to which a weak object pronoun can be raised; one of them is called 'Long Object Shift' or 'LOS'. In this paper, I deal with argument structures in constructions with LOS in Old Swedish. The purpose is to prov
The lack of sources that generates intense THz pulses have in many years limited the field of THz science. Until recently intense THz pulses have been hard to generate using nonlinear crystals such as Lithium Niobate (LiNbO3) with high efficiency. In this thesis a method is presented for achieving short and intense THz pulses through optical rectification using the recently developed tilted pulsef
Bakgrund: Andelen äldre ökar vilket medför större utmaningar för hälso- och sjukvården att kunna ge den vård som krävs. Detta innebär att det i framtiden sannolikt kommer att ställas ännu större krav på tillgången till god vård och omsorg för äldre. Syfte: Studiens syfte var att undersöka äldre personers upplevelser av kontakten med äldrevårdsmottagningar. Metod: En intervjustudie utfördes med 13
Evaluation of Standards and Techniques for Retrieval of Geospatial Raster Data - A study for ICOS Carbon Portal Geospatial raster data represent the world as a surface with its geographic information which varies continuously. These data can be grid-based data like Digital Terrain Elevation Data (DTED) and geographic image data like multispectral images. The Integrated Carbon Observation System (I
Övervikt bland barn leder till fysiska, psykiska och sociala konsekvenser, även in i vuxen ålder. Då barnhälsovårdssjuksköterskan ska arbeta hälsofrämjande och preventivt blir förebyggande av övervikt en naturlig del av arbetet, där samtalet utgör ett verktyg i omvårdnaden. Tidigare forskning påvisar både svårigheter och förutsättningar gällande samtal med föräldrar. Föreliggande studie syftar til
Kommuner i Sverige har vanligen ett stort markinnehav vilket medför att deras försäljning av mark är central för byggnationen av nya bostäder. Utöver detta har kommunen planmonopol, vilket ger dem ensamrätt att besluta om markanvändningen. Dessa två faktorer ger kommunen makt att påverka och styra bostadsbyggandet i stor utsträckning. För nybyggnation av bostäder är byggherrarna beroende av att fåMunicipalities in Sweden usually have large land holdings, which means that their sale of land is central for construction of new housing. In addition to this the municipalities have planning monopoly, which gives them the exclusive right to decide on land use. These two factors give the municipality power to influence and control the construction of new housing extensively. When it comes to const
This thesis explores how a market for grid-scale battery energy storage systems (BESS) can become reality in Sweden. Higher penetration levels of distributed, variable renewable energy (VRE) from wind power challenge the incumbent energy regime and require new solutions for the grid integration of renewables. As a consequence, a more flexible power system is needed in order to deal with the induce
The MICOS complex protein MicF has recently been identified to play a vital role in the mitochondrial DNA inheritance checkpoint, a control system that halts cell cycle progression in cells lacking mitochondrial DNA (mtDNA). We show in this report that another member of the complex, MicA, also plays an important role in the mtDNA inheritance checkpoint as its deletion led to cell cycle progression
The ongoing climate change may have devastating consequences all over the world. Most scientists are in agreement that the cause of this global environmental problem is anthropogenic releases of greenhouse gases, of which the main contributor is the combustion of fossil fuels. In order to limit these effects, it is imperative to take action immediately, globally as well as locally. Earlier resear
Studiens syfte var att undersöka effekter av fysisk träning på emotioner och psykiskt välbefinnande för tio individer i åldern 18–35 år. Intervjumaterialet analyserades med tematisk analys och nio teman genererades: Att släppa allt annat, Något att vara stolt över, En källa till glädje och energi, Pressen att prestera, Sorgen att inte kunna träna, Rädslan att förlora formen, Hindrar mig från att fThe objective of this study was to gain deeper understanding for the impact of physical exercise on emotions, and psychological well-being in ten healthy adults aged 18–35. Semi-structured interviews were conducted based on six main areas: Information, Significance of exercise, Emotions, Emotional regulation, and Cancelled exercise. Thematic analysis was performed and nine themes were generated: L
The process of how a maximum level is created for mycotoxins in the European Union is described here. The focus is on the mycotoxin T-2/HT-2 that is formed by Fusarium, a fungus that infects grains. T-2/HT-2 has been an issue for a long time without having a maximum level. This literature study will give an overview of how the process of creating a maximum level works. Risk analysis is the name
Långvariga avtalsrelationer, särskilt de som löper på obestämd tid, löper stor risk att utsättas för ändrade förhållanden och oförutsedda händelser. Frågan om ändrade förhållanden och hur dessa inverkar på avtalet och avtalsrelationen tillhör ett av avtalsrättens mest grundläggande problemområden. Fokus i denna uppsats ligger på omförhandlingsklausulerna som medel för avtalsparterna att själva anpLong-term contractual relationships, especially those that run indefinitely, are at high risk of exposure to changing circumstances and unforeseen events. The issue of changing conditions and their impact on the contract and the contractual relationship is one of the basic problem areas of the contract law. The focus of this essay is that of the renegotiation clauses as a means for the contracting
Technology is a growing industry and shows little sign of stopping. Employees of technology firms are of a particular type both in terms of racial composition and in terms of their consumption wants and needs. The following paper follows several trends that are emerging in cities and tries to apply these trends in order to examine the changing demographic structure of cities and neighborhoods in p
“The important criterion for a graph is not simply how fast we can see a result; rather it is whether through the use of the graph we can see something that would have been harder to see otherwise or that could not have been seen at all.” William S. Cleveland When presenting graphs for people with visual impairments the solutions found on the market today often present pure data values only. Over
Advantages and disadvantages with organic production have been studied in the scientific community and is greatly debated. Demands for organic products have risen the past years in Sweden and the objective in one of the governments environmental goal is to reach a 20 % organic production. But is organic production increasing sustainability in the agriculture sector? This study aims to compare orga
Carrot juice concentrate (CJC) produced from fresh carrots is used in various applications in the beverage industry. Its quality is mainly defined by the carotenoid concentration which in turn strongly depends on the quality of the raw material and the processing technique. Manufacturers are constantly searching for new ways to produce a high-colour CJC. Thermal, enzymatic and mechanical treatment
