Ändrade levnadsvanor i västerländska länder har lett till en ökning av sjukdomar så som IBS, infektioner i mag- och tarmkanal och allergier. Det har dessutom observerats att mikrofloran förändrats och goda bakterier så som Limosilactobacillus reuteri försvunnit. Mag- och tarmkanalen har därmed förlorat sina goda soldater mot patogena fiender med dysfunktionell balans som resultat. Därför är det inThis master thesis work was performed in collaboration with BioGaia AB, a Swedish biotech- company producing probiotic supplements containing the bacteria Limosilactobacillus reuteri. The products provided by BioGaia contain live microorganisms. Therefore, a method suitable for the correct enumeration of living cells is crucial in probiotic samples and today the so-called plate count method is use

Då klimatfrågan blir större och viktigare än någonsin är det viktigt att alla olika aktörer tar sitt ansvar och aktivt arbetar för ett bättre klimat. Byggsektorn har ett stort ansvar i denna fråga och något som kan minska utsläppen är just att minska energibehovet i byggnader. Genom att reducera köldbryggorna minskas även andelen energi som behövs för att värma upp en byggnad. Det är dock inte endAs the climate issue becomes more significant and critical than ever, it is essential that all different actors assume their responsibilities and actively work for a better climate. The construction sector has a great responsibility on this issue, and something that can reduce emissions is to reduce energy consumption in buildings. By reducing the thermal bridges, the proportion of energy needed t

To improve the abrasive wear resistant which is governed by a combination of both high hardness and toughness, WC particles were used to reinforce the Hadfield steel. This latter is known with its good work hardening property. WC is mainly considered for its combination of suitable hardness and toughness. Various characteristic techniques were applied to study the microstructure, interface layer,

This paper examines the editorial practices of authors and editors documented by five authors writing “Debutantbloggen” in 2020. It does so with the intention of examining to what extent editing is made visible by said authors and to what extent this editorial labour can be said to be collaborative. It argues that cultural attitudes rooted in the Romantic myth of the author and of the literary wor

We seek to better understand the relationship between an anisotropic distribution of partons in the initial state of pp-collisions and the amount of elliptic flow. We do this through the implementation of a new model that is based in generating positions for multiparton interactions from the uneven volume created by the overlap of two Gaussians. We then examine how this asymmetric probability dens

Hadfield Steels make up a significant group of steels that can perform with their higher strength, excellent wear resistance, and good formability. To achieve this distinctive behavior along with the alloy compositions, heat treatment is also a vital factor. Alloy carbides can be controlled with various heat treatment techniques, as they directly affect the loss in strength, which eventually leads

När en organisation väljer mellan att hyra eller äga lokaler finns det för- och nackdelar med båda alternativen. Väljer organisationen att gå en slags mellanväg genom att hyra lokaler via ett triple net upplägg står de inför utmaningar unika för den sortens upplägg. Denna rapport har som syfte att ta reda på hur företag kan dra fördel av triple net-avtal samt vilka förutsättningarna för detta äWhen organizations choose between leasing and owning facilities there are benefits and drawbacks associated with both alternatives. If an organisation proceeds with a middle ground solution by leasing using a triple net lease, they will instead face challenges unique for that lease type. The aim of this thesis is to find out how companies can take advantage of triple net leases and what the requ

Syftet med arbetat är att undersöka hur skrivprocesser behandlas i läroböcker för svenska 1 på gymnasiet. Jag undersöker om och hur läroböcker berör skrivprocesser samt om skrivprocesser finns med explicit eller implicit. I uppsatsen granskas fem läroböcker utifrån en kvalitativ metod. Läroböckerna jag valt ut har tryckts efter införandet av lgy11, vilket innebär att jag har valt bort ett historis

A secure living for undocumented victims of trafficking is knowing that the security exists – and that there is a possibility to be offered and provided support. The purpose of this study is to examine the work against human trafficking for sexual purposes, more specifically the study examines what support undocumented women, that are victims of trafficking, are entitled to in Sweden. Furthermore,

Intradialytic hypotension (IDH) is a major drawback of haemodialysis and occurs in more than every fifth dialysis treatment. There is a need for real-time measurement, with an ability to detect IDH before it occurs. Photoplethysmography (PPG) may provide sufficient information about hemodynamic status to prevent IDH. In particular, the venous component may be useful. This thesis aims to investiga

Kultur är en essentiell del i många människors liv, speciellt hos bikulturella individer för att de upplever två kulturer inom sig. Vi vill bidra med kunskap och förståelse inför bikulturell positionering och hur detta upplevs. Tidigare forskningsstudier konstaterar att bikulturella individer lever i konflikt med sin identitet under lång tid, men att de efterhand accepterar den. Denna studie grund

Armed conflicts have definitive wide-ranging and diverse impacts on the environment. This thesis examines associations between conflict and land cover change in Cambodia, focusing on the last decade (1989 - 1998) of a thirty-year long Civil War. This was done by comparing trends in forest cover and vegetation seasonality between two regions of Cambodia; one conflict zone, and one no-conflict zone,

Nigeria is, by population, the largest country in Africa and their economic growth will be a key part in the world reaching the goals of eradicating poverty. This paper investigates the economic growth performance of Nigeria and the relationship between oil and the GDP performance by using growth accounting, ARIMA, VAR and VEC models. Through the ARIMA and VAR models, the GDP is forecasted until 2

I mars 2020 rasade Tarfalahallen i Kiruna. Idrottshallens takkonstruktion bestod av långa underspända limträbalkar upplagda på limträpelare. Balkarna var underspända med hjälp av två trycksträvor som stöttades med dragband av stål och anslutningen mellan trycksträvorna och balken bestod av spikförband. Statens Haverikommission (SHK) har en pågående utredning kring raset, och har hittills bland annDuring March of 2020 a large-span sports arena, Tarfala hall, built 2015, collapsed in northern Sweden. The main load-bearing girders with a 54 m span, were high and slender glulam beams supported underneath by a cable system via vertical struts. Investigations concluded that the failure was initiated by lateral buckling of the struts and slender beam, in spite of lateral stabilization by a corrug

Today, we are creating and building more than ever. While buildings rise from the horizon, the consumption of building materials increases massively. More than 22% of global carbon dioxide emissions come from the consumption of building materials such as concrete, steel, and aluminum, etc. 55% of embodied carbon in a conventional building is in the structure and substructure (Smedley, 2019). Hence

This report covers the development process of finding the best attach method for a plastic cover to a metal chassis of a sensor. Several manufacturers of electronic equipment use screws as a semi-permanent way of attaching a cover to their product. However, this method is not always appreciated as it takes up volume in the product and makes the exterior of the product unattractive. The project has

The purpose of the project was to develop one of their products through a user-centered design process. To determine which product had the greatest development potential, an evaluation of three products and the associated app was conducted. A custom heuri

The study is about architecture which helps restore disconnected relationship. The site is an empty military base which had been occupied by the U.S army right after the Korean War and has been physically and emotionally disconnected from the city and the citizen. The aim of the design is to encourage people to revitalize the lost connection by spending time in the architecture. In accordance with

Jordens invånarantal ökar med rasande fart vilket också leder till ett ökat behov av mat. Detta har resulterat i ett intensivt jordbruk som bland annat kan orsaka skada på de livsviktiga organismerna som lever i marken. Organismer som lever i marken kan bland annat vara bakterier, svampar och även större organismer såsom daggmaskar. Tillsammans utför dessa viktiga funktioner i marken som är avgöraThis field study was done to get an understanding of how the agricultural method called “structural liming” might affect soil organisms in a negative way. Soil organisms are crucial as they perform biological processes that improve good soil structure. This is important as it enables sustainable food production, today, and in the future. Structural liming is used on clay soils to improve soil stru
