Phosphate is fundamental for optimal growth and reproduction for plants. However, due to low solubility, not all phosphorus in the soil is available to the plant. It has recently been discovered that plants can take up complex phosphate-containing organic compounds, such as phospholipids. This depends on membrane transporters, more specifically lipid flippases. In the model plant Arabidopsis, the
Bakgrund: Screening är en prevention för att upptäcka förstadier till cancer och kvinnor betraktar ofta screening av livmoderhalscancer som en rutin för att bekräfta hälsa. Det är även väldokumenterat att besked om avvikande cellprover kan orsaka betydande oro och stress hos kvinnor. Syfte: Beskriva kvinnors upplevelse av att få ett avvikande resultat från screening av livmoderhalscancer. Metod: L
This study investigates the discourse in the art criticism written between 1895 and 1920 concerning women sculptors in Sweden. Primarily, it focuses on the criticism regarding Sigrid Blomberg (1863–1941), Agnes de Frumerie (1869–1937), Ruth Milles (1871–1941), Alice Nordin (1871–1948) and Gerda Sprinchorn (1871–1951). At the turn of the twentieth century Sweden was a patriarchal society; women di
Uppsatsens syfte är att skapa förståelse för samt att definiera vad ledarskap och motivation är, och kunna få en förståelse för hur olika ledarskapsstilar påverkar medarbetares motivation. Uppsatsen är en forskningsöversikt då författaren anser det vara givande att kunna bidra med en överblick inom det breda forskningsområdet. Uppsatsens analys påvisar att ett transformativt ledarskap har ett över
Spectral estimation can be done using different techniques, where averaging the periodogram using multiple windows is one of the techniques. When using multiple windows, the spectral estimate is commonly obtained by having the windows for the subspectra equally weighted. The goal of this thesis is to find weights for the windows that give a better spectral estimate than the equally weighted spectr
Private set intersection is a technique for finding the intersection of (two) parties' sets without disclosing anything else, and it finds it use in e.g. contact discovery, finding friends who are already on a social platform. Multi-party threshold private set intersection is an extension of this which allows multiple parties and only reveals the intersection if the intersection is larger than
The observable Rt is investigated in the Monte Carlo Model Pythia in order to better understand results from experimental data obtained in the ALICE detector at CERN. The purpose is to reproduce the experiment in a simulation and use the features proposed by Pythia to dig into the unexpected outcomes. The analysis is conducted using (∆φ, ∆η) two particle correlations. Three different methods are u
This thesis proposes a method for how to find duplicated 3D points in a single Structure from Motion point cloud. Together with related articles, this forms a possible solution to the loop closure problem. The proposed method works by first selecting candidate pairs of 3D points by comparing BRIEF descriptors of all points. The second step consists of using RANSAC to select the best out of many
I Alternativa övningsmetoder för musiker – del 1 presenteras olika sätt på vilka musikaliska färdigheter kan övas genom mentalisering och andra alternativa övningsmetoder som inte inkluderar användande av musikernas huvudinstrument. Den visar också hur dessa metoder kan kombineras. Här beskrivs även hur och varför dessa arbetssätt fungerar för musikalisk instudering individuellt och i en duo samt Alternative Methods of Practising Music – A study of practising without one’s main instrument for single musicians and small ensembles – Part 1 presents different ways in which musical skills can be practised through imagery and other alternative methods of practising that do not involve the use of the musicians’ main instruments. It also shows how these methods may be combined. Furthermore, it de
Det finns ett brett forskningsunderlag som talar för lukt som en effektiv minnesledtråd för att bättre återkalla tidigare inkodad information och minnen. Lukt kan även fungera som en minnesledtråd för att återskapa samma kontextuella förutsättningar som vid inkodningstillfället. Mycket forskning tyder även på att människor kommer ihåg händelserelaterad information lättare än detaljinformation. StuThere is a broad research base that speaks for odor as an effective memory cue to better recall of previously encoded information and memories. Furthermore, odor can act as a memory cue to recreate the same contextual conditions as at the time of encoding. Research also suggests that people remember action-related information more easily than detailed information. The study examined whether physic
This thesis has investigated the relationship between market capitalization to GDP ratio relative to the Capital asset pricing model (CAPM) and Fama French three-factor model (FF3M). More specifically, the applicability and significance of market capitalization to GDP ratio to describe the relationship between excess return and risk. The study was conducted on OMX Helsinki and Bolsa de Valores de
Skånes konsumtion kan påverka en hållbar utveckling i världen Hur påverkar lokala politiska åtgärder implementationen av Agenda 2030? Finns det en risk för att åtgärder motverkar en hållbar utveckling? En växande konsumtion är en av världens stora hållbarhetsutmaningar. Överexploatering av naturresurser och föroreningar i luft och vatten är några av konsekvenserna. Konsumtion i Skåne påverkar omgThe pace of implementing the 17 global sustainability goals must increase drastically. The complexity of the goals is a challenge and mapping out interactions between them is identified as a way to explore their system properties and improve implementation. Sustainability goal 12 (sustainable consumption and production) has been suggested as one of the areas that affects and interacts with most ot
Produktionen av kemikalier på Perstorp AB genererar kontaminerat avloppsvatten som renas i industriparkens egna avloppsreningsverk innan de kan återanvändas till processen igen. Industriparken i Perstorp har villkor från avloppsreningsverket på hur mycket vatten som fabrikerna får släppa ut till avloppsreningsverket. Det finns fortfarande kapacitet kvar innan villkoret uppnås, men marginalerna serThe production of chemicals at Perstorp AB generates contaminated wastewater that is treated in the industrial park’s own sewage treatment plant before it can be reused in the process again. The industrial park has conditions from the sewage treatment plant on how much water the factories may discharge. There is capacity left before the condition is reached, but the margins look to decrease in the
Demand for the usable water is accumulating globally in parallel with the population growth and the industrial revolution. Nevertheless, availability and accessibility of the usable water is progressively subsiding due to many environmental and socio-economic reasons. This discrepancy can lead the world to a water crisis unless it takes necessary actions to enhance the sustainable use of existing
Since 1993 Sweden has, de facto, had an independent central bank, which was verified, de jure, in 1999. The independence of the central bank has during the 2010s been accompanied by drastic drops in the repo rate for the country and the introduction of new monetary policies for Sweden to continue pushing their expansive monetary policy. This essay will be about the overall effect on the inflation
Insects can find their way home as good as some of us Have you ever been out on field during a summer day, seen bees and ants collecting food far away from their home, and thought: “How do they find their way back home?”. Firstly, understanding insects’ navigational strategies and the underlying neurons responsible for the navigation direction and speed is the first step towards our understanding
Field voles fight against pathogens Why did we study field voles (Microtus agrestis)? Well, field voles can tell us how the immune system develops in wild mammals. The immune system develops because pathogens develop, it’s like an arms race. If pathogens increase their infectivity, the field voles need to increase their immune defense. If not, the species will not survive. How do field voles pro
Genom att använda algoritmer och mjukvara kan gamla metoder inom molekylärbiologin effektiviseras. Målet med arbetet var att framställa ett program som automatiserar produktionen av överlappande primrar för kandidatgener. Genom att ta tre olika inputs från användaren så skulle förslag till unika primerpar framställas. Programmet kodades i programmeringsspråket python och biblioteket Primer3 använd
In 2013, the previous Mexican federal government passed a constitutional reform of the energy sector that set the grounds for the use of fracking at a national scale. Less than two years later, a strategic policy document was published, mapping a whole set of areas whose deposits require the use of fracking to be exploited. Part of these endangered areas are located in the region of La Huasteca Po
