A good head of beer gives nice texture and prevents releasing of aroma. The beer foam stability depends on numerous parameters. In this study, it was focused on the interfacial rheological properties such as surface tension and dilational modulus in relation the film formation by isohumulones and beer proteins at the air-water interfaces. The isohumulones and beer protein samples were prepared indWhat makes beer foam stable? Beer is one of the most beloved beverages all over the world. When we think about a good beer, we end up with beer foam. This is because the foam prevents releasing of aroma and gives a good texture when drinking. Beer foam is a mixture of air and liquid containing beer components such as ethanol, proteins, hop acids and other nutrients. Beer proteins are from the bar

Since the 1950’s, a wide range of titanium alloys has been developed. Attractive titanium properties are the high strength-to-weight ratio, resistance towards corrosion, low thermal conductivity and low thermal expansion. Properties that make titanium alloys difficult-to-machine materials are those of low thermal conductivity, chemical reactiveness and the high strength, requiring low cutting data

Based on fieldwork interviews from two different trade unions in Luanda, this study aims to reflect on the role of civil society for the consolidation of democracy in Angola, and in particular, the challenges of trade unionism and its effects on democracy. Using the meth-od of inductive reasoning to process data, it first addresses themes derived from the inter-views such as Financial struggles, T

Denna syftar till att undersöka de argument som Obama-administrationen uttryckte angående ett amerikanskt militärt ingripande i Syrien till följd av de syriska regimens användning av kemiska vapen år 2013. Under sitt presidentskap uppgav Obama att USA drar en "röd linje" vid användade av kemiska vapen mot civila, men hotet visade sig vara tomt ett år senare när tusentals människor dödadeThis paper aims to examine the arguments proposed by the Obama administration regarding a U.S. military intervention in Syria due to the use of chemical weapons by the Syrian regime in 2013. During his presidency, Obama stated that the He draws a ‘red line’ at the use of chemical weapons against civilians, but the threat proved to be empty a year later when thousands of people were killed in a che

The current debate concerning land acquisition for commercial agriculture is whether it can contribute to poverty reduction by developing communities through successful agribusiness, or whether it leads to dispossession of traditional land users. Thus, this research is a case study of the African Agricultural Development Company (AgDevCo) and their irrigated farming hub in Babator, Ghana. It will

Vi lever i spännande tider brukar det heta. Det är ett slitet uttryck, men kanske mer sant än någonsin och Alexander Bard och Jan Söderqvist försöker i sin Futurica-trilogi visa att det inte bara är vår fysiska omgivning som är på väg att helt ändra skepnad – även hela vår världssyn och metafysiska system står i begrepp att kollapsa och ersättas av något nytt. Sant eller inte står det i varje fall

Korn innehåller naturligt högre nivåer av kostfiber vilket skulle kunna användas mer i hälsofrämjande syften, men istället används det främst till malt för öl- och whiskyindustrin och är ofta inte beaktat som en kandidat för andra applikationer. I denna studien har fem olika kornsorter undersökts ur ett tekniskt perspektiv och ett hälsoperspektiv för att på så sätt kunna identifiera korns styrkor,Barley naturally contains high amounts of dietary fibre, however it is not widely used in health promoting purposes. Barley is traditionally used for malting in beer and whisky and it is often overlooked as a candidate for other applications. In this study five barley varieties are evaluated from a technical and a nutritional point of view. The aim of the study is to conduct a literature review re

Syfte Syftet med pilotstudien var att jämföra de två behandlingsmetoderna röstbehandling och högläsning för att utvärdera vilken metod som var mest effektiv i behandlingen av spolformad glottisinsufficiens. Metod Studien hade en case cross-over design. I studien ingick fem deltagare mellan 67-83 år. Deltagarna randomiserades in i två grupper. Studien pågick i 12 veckor varav åtta veckor gavs inter

The purpose of this project was at first to explore textiles. It started off by a visit to The Swedish School of Textiles in Borås. I was introduced to the basics of textiles and was shown new textile materials at Smart Textiles. Coming home, I came to the conclusion of doing it my way, with the view of an Industrial Designer. Having prior experience with a similar project I knew that it was imp

In Chichigalpa, Nicaragua, an unusual amount of manual sugar cane workers suffer from Chronic Kidney Disease of undetermined causes (CKDu), a disease with very high fatality rate in poor commu- nities. Harsh working conditions is a contributing factor, and this thesis uses tool design to conceive constructive solutions to address tangible parts of a seemingly overwhelming problem.

This process and material driven project was from the beginning focused on wast materials. The fact that the world population is rapidly increasing made me think of it as a possible source of material, instead of just an outlet of waste. With an interest in the controversial, I decided to work with human hair. The key structural material in hair is a protein called alpha-keratin. Early hopes of pr

De urbana vattenkällorna i Centralasien hotas av både lägre kvalitet och kvantitet samtidigt som befolkningen ökar. Detta väcker en problematik som kan sammanfattas med frågan: hur kan en hållbar expansion av vattenförsörjningssystem utföras för att fler ska få tillgång till säkert dricksvatten och ett ordnat avlopp?The aim of this Thesis Project was to develop a general risk management approach for assessing the expansion of a centralized water system in Central Asian countries. In order to develop the general approach, a case study was performed in Pavlodar, Kazakhstan. The basis for developing the approach was literature study, data collection, interviews, focus group discussion (FGD) and observations made

The popularity of voluntourism (volunteer tourism) over the last couple of decades has developed rapidly into a global phenomenon. The concept of voluntourism seeks to align tourism with development initiatives occurring often within the Global South with the assistance of volunteer sending organisations (VTSOs). At first glance, voluntourism is seen as distinctly noble in its intentions with altr

Med 1920 års giftermålsbalk (1920:405) introducerades ett nytt system för makars egendomsförhållanden i svensk rätt. I denna ordning, som utgör gällande rätt än i dag, betonades makars självständighet genom bevarandet av den individuella äganderätten efter äktenskaps ingående. En rätt att vid den äktenskapliga gemenskapens upplösning få vara med att dela på den andra makens förmögenhetsvärde, giftWith the introduction of the Marriage Code (1920:405) in 1920 followed a new property regime for spouses in Swedish family law. This regime, which is in effect today still, emphasised the spouses’ remaining independence after entering of marriage through a remaining individual property ownership. Moreover, a right to share the value of the other spouse’s property at the dissolution of marriage, th

Vid domstolens avgörande av vårdnads- och boendefrågan kan beslut fattas antingen om att vårdnaden ska anförtros föräldrarna gemensamt eller en av föräldrarna samt om barnet ska bo växelvis hos båda föräldrarna eller stadigvarande hos en av dem. Bedömning ska alltid göras i varje enskilt fall och avgörande är vad som är barnets bästa, vilket stadgas i portalparagrafen i 6 kap. 2 a § föräldrabalkenIn the court’s judgement in matters of custody and residency of a child, decisions can be made to either entrust custody to both parents or one of the parents, and whether the child is to live alternately with both parents or permanently with one of them. The assessment is always to be made in each separate case with the best interest of the child, which is stipulated in chapter 6, section 2 a of

Internet of Things är ett fenomen som gör det möjligt för en användare att integrera internet i sitt vardagsliv. När vardagsföremål kopplas upp till internet, genereras mängder av data som kan analyseras för att kunna användas i olika syften. Denna uppsats kommer att förklara Internet of Things samt de teknologier som har möjliggjort utvecklingen. Målet med uppsatsen var att undersöka om allmänhet

En mänsklig rättighet beskrivs som en så fundamental rättighet att varje enskild anses kunna hävda den gentemot det allmänna. Trots det ansågs det inte finnas något behov av ett mellanstatligt skydd innan andra världskriget. Då ansåg man att det var varje stats ensak hur de behandlade sina medborgare men efter andra världskriget aktualiserades nya krav. Detta ledde till att Europarådet bildades 19A human right is described as such a fundamental right that every individual is considered to be able to claim it against the public. Before the Second World War the general opinion was that there was no need for an intergovernmental protection. At this time, it was considered to be every states responsibility how they treated there citizens, but after the Second World War new demands were made. T

Floods are probably the most frequent, widespread and disastrous hazards of the world. Almost every year, Sweden and Nepal are affected by floods though their nature and impact differs due to complete different geographical and hydrological setting. This study aims to develop Hydrologic Engineering Centre’s Hydrologic Modelling System (HEC-HMS) and Hydrologic Engineering Centre’s River Analysis Sy
