Study of tomato fiber fragmentation in the high-pressure homogenizer

Homogenization is commonly used in many food processes in which products pass through a narrow gap causing break down of large particles into smaller one thereby reducing creaming and sedimentation of the products. This study aims to investigate fragmentation of tomato fibers and test which breaking mechanisms are dominating in a high-pressure homogenizer. The study also includes the influence of

Skin barrier: Extraction and characterization of Stratum Corneum lipids

The structure and dynamics of isolated Stratum Corneum lipids in different temperatures and hydration conditions was investigated using natural abundance 13 C NMR and X-ray scattering. In order to isolate the lipids a new extraction method was tested. The novel aspect of this method was its ability to extract more lipids from SC. This new method (referred to as Method II in-text) was further modif

How do Personal Values Relate to Strategic Thinking

In the light of globalization and a growing demand for handling complexity and uncertainty, the ability to think strategically is a vital asset for future managers. However, there is no consensus in the definition of strategic thinking. Nevertheless, many theorists suggest on a relationship between strategic thinking and personal values, though the detailed specifics in this connection is inadequa

Power and Resistance: exploring strategies of self-empowerment among Syrian asylum seekers in Sweden

This thesis explores the experiences of Syrian asylum seekers in Sweden, who are waiting for their decision or have recently received it. The empirical data have been collected through semi-structured interviews with ten women and men during a month-long fieldwork conducted in the autumn of 2016 in an asylum centre located in the south of Sweden. The research queries the regimes of power that shap

Characterization of geographical variation in antioxidative active Eucalyptus camaldulensis extracts : for future use as biopesticides in Burkina Faso

En kraftig befolkningstillväxt och torrare klimat är två av de största utmaningar som väntar Burkina Faso i framtiden. Det är ett kustlöst land, till ytan ungefär två tredjedelar av Sverige, som idag har en befolkning på närmare 20 miljoner - en siffra som kan ha fördubblats redan år 2045. Som för många andra utvecklingsländer är jordbruket helt avgörande för Burkina Faso. Det är en sektor som idaThe current use of pesticides in Burkina Faso has been described as problematic. An alternative to synthetically produced pesticides is products based on naturally occurring substances, e.g. from plants, so-called biopesticides. In this study aqueous and ethanol extracts from Eucalyptus camaldulensis collected at three different geographical locations in Burkina Faso are investigated with regard t

Derivation and stability determination of black hole metrics

The Schwarzschild metric and the Kerr metric describe the gravitational fields around static and rotating black holes, respectively. Here, we derive the Kerr metric in a simpler way than how it was derived originally and determine the stability of the Schwarzschild metric. The Kerr metric was derived by using the Einstein-Hilbert action as well as directly from the Einstein field equations. In ord

Point. 3

Abstract: Internet of Things (IoT) devices play a huge role in our lives today, and this constant connectivity will continue to grow. As these products are becoming an increasingly more important part of our homes, it is interesting to explore the design of them. This thought of interest led to a collaboration with Minut AB and the development of their product called Point. In order for th

The Impact of Inflation Targeting Lite regime on Economic growth: A case study of Uganda

Price stability is an element of macroeconomic stability that is necessary to achieve economic growth in any economy like Uganda. There is no doubt that Inflation Targeting Lite (ITL) regime as a monetary policy framework has helped to achieve price stability through reduced inflation rates and inflation volatility in Uganda and other countries (Nabbosa, 2017). The ultimate goal of a monetary poli

Vem ropar högst?

Problemformulering: Influencer marketing är ett växande fenomen som fortsätter att utvecklas och har blivit populärt inom dagens marknadsföring. Utifrån en granskning av tidigare forskning inom influencer marketing har vi sett en avsaknad på forskning om hur företag förhåller sig till influencers och väljer samarbetspartners. Det är därmed av vikt att företag vet hur de ska arbeta med influencer m

Stratigraphy, sedimentology and geophysical assessment of the early Silurian Halla and Klinteberg formations, Altajme core, Gotland, Sweden

Altajmeborrkärnan togs upp i närheten av Buttle centrala Gotland 2015. Projektet är ett resultat av en internationell borrkampanj mellan geologiska institutionen vid Lunds universitet och Iowa universitet, USA. Borrningen gick ned till den underliggande ordoviciska lagerföljden på ett djup av ca 330 m. I denna masteruppsats har karbonatsedimentologin och gamma ray-loggen från de översta 137 m av bThe Altajme drillcore was recovered from near Buttle in central Gotland in 2015. The core was drilled in outcrop belt of the late Wenlock (Silurian) Klinteberg Formation as a result from an international drilling campaign between the Department of Geology at Lund University and Iowa University, USA. The coring continued to the top of the underlying Ordovician strata at a depth of ca 330 m. In this

Dimensionering av tillfälliga vägar - en modellansats

Pavements in Sweden today are often designed to have a life span of at least 20 years. This means that pavements are designed to endure all seasons for 20 years: 20 winters, 20 spring thaws. 20 summers and so on. For those occasions where a life span less than 20 years is requested, there is no standardized method to use today. Designing is instead usually done either by scaling down the results f

Det skolastiska ockerförbudet: En analys och jämförelse av Thomas av Aquinos och Gerhard av Sienas argument för ockerförbudet

The aim of this essay is to investigate two scholastic theologians’ views on usury, to compare their arguments for the Christian usury prohibition and to see whether one can see a development in argumentation. The examined writers are St. Thomas Aquinas and Gerard of Siena and their works Summa Theologiae, De Malo, and De Emptione et Venditione; and De Usura, respectively. Before the investigation

Jag gillade att skada människor, det var min grej - En kvalitativ studie om hur man inleder, upprätthåller och avslutar en kriminell karriär

Vad är det som gör att en människa är benägen att utsätta sig för de risker som finns i att vara kriminell, vad är mentaliteten under tiden och hur kommer man ur det. Uppsatsen berör processen för individer som valt att inleda, upprätthålla och avsluta en kriminell karriär. Detta undersöks genom intervjuer med fyra stycken före detta kriminella personer. Genom denna kvalitativa uppsats söktes pers

Faktorer för framgång. En kvantitativ studie om vad som påverkar utgången för deltagare i en kommunal arbetsmarknadsinsats

De senaste årtiondenas utveckling av svensk arbetsmarknad och arbetsmarknadspolitik har gjort att fler grupper förväntas klara sin försörjning genom arbete. Flera förändringar har genomförts som tillsammans innebär att fler arbetslösa blir kommunernas ansvar vilket har lett till att allt fler kommuner i växande utsträckning bedriver arbetsmarknadsåtgärder. För personer som anses befinna sig längst

Inflated Multinomial Matching for Anchor-Free Object Detection

Algoritmer för att automatiskt förstå innehållet i bilder och videor har sett en enorm utveckling under de senaste åren. Trots framsteg i hur väl algoritmerna kan läras till att förstå bildinnehållet på egen hand så krävs fortfarande en viss grad av handhållning och vägledning från områdesexperter som utvecklar och tränar algoritmerna. När positionen och dimensionerna på ett objekt av intresse skaThis thesis presents a novel matching strategy, Inflated Multinomial Matching, which enables training of anchor-free object detection models based on convolutional neural networks. An important aspect of detection models is the integral usage of anchor boxes, where an anchor box is a bounding box with a preset and constant location, size and shape in the image. The matching strategy presented remo

EBL Patterned ITO Contacts for Single Nanowire Devices

Transparenta material som kan leda ström är viktiga för bland annat solceller. Nu har ett sådant material, indiumtennoxid (ITO), för första gången tillverkats i rekordliten storlek för att användas till exotiska solcellsprover på nanoskalan. ”Konventionella” solceller lider av ett problem som kan liknas vid grötproblemet Guldlock stötte på hos de tre björnarna: när solen lyser på solceller kommerNanowires have attracted interest as fundamental building blocks for electronic and optoelectronic devices as well as for fundamental research. Photonic studies of single nanowire devices typically involve patterning of metal electrodes for electronic access, yet plasmonic ef- fects between the metal contacts and the light source may perturb experimental measurements. An alternative to conventiona

An estimator of winter loss of honey bees in Sweden

The aim of this thesis is to suggest a statistical model to estimate the loss rates of honey bees during winter in Sweden. The estimator is to be based on annual summary statistics, collected by the Swedish beekeeping organisation. Regional specific estimates for winter loss rate is derived by a spatial and temporal hierarchical model with binomial response. The model is updated by Bayesian infere

Performance of jet subtraction in pPb and PbPb collisions, without collectivity

We investigated the performance of basic jet subtraction, by the utilization of jet reconstruction generally used at the Large Hadron Collider (LHC). This was done by studying Z-bosons, in the dielectron decay channel, and the associated jet correlation in pp, pPb and PbPb collisions, using datasets generated by the Monte Carlo generator PYTHIA8. The PbPb collisions at $\sqrt{s_{NN}} = 2.76$ TeV a
