The purpose of this research is to achieve a deeper insight of the emulsifying, suspending, and gelling properties of the meat proteins and see the possibility to use them to produce reduced-salt emulsion-type sausages. Sarcoplasmic and myofibrillar proteins were extracted from pork (longissimus dorsi, LD). Firstly, their aggregation behaviors in different salt concentrations – namely, 0.15 M, 0.4
Sammanfattning Detta arbete har delats in i två delar. Den första delen handlar om olika energilagringstekniker. Den andra delen handlar om att lagra egenproducerad elenergi i ett flerbostadshus. Syftet med första delen har varit att samla information om olika energilagringstekniker i en kunskapssammanställning genom att studera dess funktion, aktuella status och framtidsutsikter. Den andra delen Abstract This master thesis is divided into two parts. The first part deals with a general study of different energy storage systems. The second part deals with the possibility to store own-produced electricity from solar panels in a multifamily residential area. The purpose of the first part was to collect information about different energy storage systems in a general study, and examine their di
Varje dag pågår parallellt ofantligt många kemiska reaktioner i vår kropp vars funktion är att bryta ner och bygga upp olika typer av molekyler. Ett samlingsnamn för de molekyler som både bryts ner och används som byggstenar i kroppen är metaboliter och disciplinen som fokuserar på studien av dessa metaboliter kallas för metabolomik. Metabolomik kan användas för att få en fördjupad förståelse för Instrumental analysis in metabolomics has proven to be a challenging topic due to metabolites having a wide spectrum of physiochemical properties and concentrations. The more conventional techniques in metabolomics include gas chromatography and liquid chromatography coupled with mass spectrometric (MS) detection. In most cases these techniques provide methods that are adequate for metabolomic res
This master thesis contributed to a project financed by the Swedish Energy Agency and managed by the housing company Eksta AB in collaboration with the consulting Company WSP. The main aim of this master thesis was to perform a theoretical optimization on the usage of own used solar electricity by transferring the surplus PV between buildings in a demonstration area in a DC-microgrid. To achieve th
Increasing demand for metals might lead to extraction of metals from materials, previously, thought of as waste. A letter by the Swedish Environmental Protection Agency and Geological Survey of Sweden from 2017 encouraged new and innovative waste treatments as well as recycling of waste produced in association with mining. The conventional treatment of acid mine wastewater creates large volumes of
Denna examensuppsats behandlar djurskydd ur ett rättsutvecklingsperspektiv från tiden innan vår tidräkning och fram till idag. Jag redogör för de ideologiska och filosofiska strömningar som lett fram till de olika förändringar som skett under århundradena. Människor har redan innan vår tidräkning haft filosofiska resonemang kring förhållandet mellan djur och människor. I uppsatsen analyseras hur lThis thesis investigates animal protection from a legislation development perspective from 400 B.C. to today. I describe the ideological and philosophical trends that have influenced the changes that have occurred throughout the centuries. People have for thousands of years had thoughtful discussions about the relationship between humans and animals. The thesis analyzes how the legislation has bee
The positive correlation between elevated expression of wingless-type mammary tumor virus integration site family member 5A (WNT5A) and metastatic potential in melanoma has been extensively explored. However, detailed mechanistic aspects regarding how WNT5A promotes increased melanoma aggressiveness remains unknown. Myristoylated alanine-rich C-kinase substrate (MARCKS), an intracellular protein c
Från giftiga potatisar till användbara proteiner Potatis är en av världens mest odlade grödor. Den innehåller både kolhydrater och proteiner och har ett högt näringsvärde. Det talas ofta om att det är viktigt att få i sig proteiner, men sällan om proteinets emulgerande, konsistengivande och skummande egenskaper. Dessa egenskaper är högt värderade inom livsmedelsindustrin. Traditionell odling harPotato protein is an industrial side product with highly desirable properties which can be utilized if the toxic glycoalkaloids can be removed in a gentle way which doesn’t damage the protein. The challenge within this project is to find an extraction technique efficient enough to remove the toxic glycoalkaloids, but still mild enough to preserve the protein from denaturation. Supercritical CO2 ex
In the last decade, there has been a substantial shift from actively managed funds to funds with passive investment strategies. This shift was also observed by Shleifer (1986), who identified that passive investment funds began to significantly increase their ownership of the S&P 500 in the period between 1975 and 1983. As the ownership of the stock market increased as the number of index fund
This study used the urban context of Brunnshög, Sweden as a real case study to assess non-visual daylight conditions in urban environments. More precisely, the work was focusing on how the light spectrum – through surrounding façade colour and window type – can have an impact on the circadian potential. A one-bedroom apartment opening onto a courtyard on the ground floor and the same apartment on
En grundvattenundersökning i ett område präglat av vattenrelaterade problem. Staden Cochabamba i Bolivia står inför flera vattenrelaterade utmaningar såsom brist på ytvatten, en ökande vattenanvändning, urbanisering och en sjunkande grundvattennivå. Samtidigt råder det en brist på kunskap angående de processer som påverkar grundvattnet i området. Något som detta examensarbete ämnar att förändra. The Central Valley of Cochabamba is located in the Andes mountain range, Bolivia. This region experiences several water related challenges such as a scarcity of surface water, an increasing water demand, a growing urbanization in groundwater recharge areas, and a declining water table due to intensive groundwater extraction. The valley has been influenced by both alluvial and fluvial depositions t
Rennet coagulation ability of milk is of utmost importance in cheese manufacturing industry since it is directly related to cheese quality and yield, then translated into economic benefit. This study examined the rennet coagulation ability and composition of milk from individual Swedish Red (SR) cows, the second most common dairy breed in Sweden. Additionally, the study explored how the presence o
Att fånga upp koldioxid från industriella utsläpp eller direkt från atmosfären och omvandla det till mer värdefulla föreningar, kallat "carbon capture and utilization", är en intressant metod för motverkandet av den globala uppvärmningen. Med en katalysator kan koldioxid och vätgas användas för att tillverka metanol som är användbart som bränsle och i kemikalieindustin. En nyligen upptäcNickel gallium alloys have recently been discovered as a promising material for the catalyzation of methanol synthesis from carbon dioxide. Due to the novel nature of the material system for this purpose, there is a large potential for optimization in terms of catalytic activity and selectivity for methanol. Optimization through engineering of phases and facets in such materials is often difficult
How the IGHV upstream sequences look like? The antibody, also called immunoglobulin (lG), can identify and bind specifically to antigens such as bacteria, viruses, and other disease-causing organisms. Its high variety is achieved by the selection and recombination of genes from normal full-length genomic genes. The antibody contains two identical heavy chains and two identical light chains. What
Does treating high blood pressure improve neurodegeneration High blood pressure, also called hypertension could damage the brain. Our research tries to understand how lowering blood pressure affects the hypertensive brain. Hypertension is the disease that people have abnormally high blood pressure. Nowadays, 1 in 5 people worldwide have hypertension, accounting for 1.13 billion people. This cause
