The Water hyacinth is one of the worst aquatic weeds in the world and it is today present on all continents except Antarctica. It causes big problems for both people and the aquatic ecosystems in many countries. A lot of research has been completed to find methods to eradicate the weed and a lot of money has been spent on management to keep waters clean. In this literature study on management meth

Utvecklingen av artificiell intelligens har tagit massiva kliv det senaste årtiondet och tekniken har stor potential att utveckla många områden i samhället. Ett av dessa områden är behandling av cancer i sjukvården. Detta examensarbete introducerar en ny metod för att träna AI-algoritmer att automatiskt dela upp och klassificera olika områden i en bild. Denna metod testas sedan för att markera ut The last decades of research in machine learning and deep learning have lead to enormous advancements in the field. One of the areas that stand to gain the most from this is the medical sector. However, the majority of deep learning models today rely on supervised learning and one considerable bottleneck in the sector's ability to adapt the technology is the need of large labeled datasets.

Vid företagsförvärv kan det finnas en önskan hos köparen att låta målbolaget medverka till finansieringen av aktieförvärvet. Möjligheterna till sådan medverkan begränsas emellertid genom det s.k. förvärvslåneförbudet i 21 kap. 5 § aktiebolagslagen (2005:551) enligt vilket aktiebolag inte får ge förskott, lämna lån eller ställa säkerhet (”lån m.m.) i syfte att gäldenären ska förvärva aktier i bolagWhen acquiring shares in a company the buyer may want the target company to contribute to the financing of the acquisition. The means of such contribution is however limited through a prohibition in Chapter 21 Section 5 of the Companies Act (2005:551) according to which a company may not grant advance, provide loans or provide security for loans (“loans etc.”) in order that the debtor or any natur

Varje år sker det tusentals olyckor i trafiken i Sverige till följd av det stora transportbehovet i samhället. Transportstyrelsen har ett mål, Nollvisionen, som innebär att ingen ska dödas eller skadas allvarligt i trafiken. För att nå målet är en åtgärd att hastigheten sänks där gång- och cykeltrafik behöver interagera med motorfordon. Det kan man göra i form av sidoförskjutningar, avsmalning av Every year, thousands of traffic accidents occur in Sweden as a result of the transportation need in society. The Swedish Transport Agency has a goal, Vision Zero, which means that no one should die or be severely injured in traffic. To reach the goal one measure is to reduce the speed where pedestrians and cyclists need to interact with motor vehicles. This can be done by chicanes, narrowing of t

Behandling av kroniska tarmsjukdomar Är PTPN23 lösningen vi har väntat på? Alla har vi sannolikt någon gång lidit av magproblem i form av smärta eller diarré. Att drabbas av kroniska tarmsjukdomar där besvären utgör en vardag är ett globalt problem, och trots att sjukdomarna är vanliga finns idag inget botemedel. I den här studien har vi undersökt om en eliminering av molekylen PTPN23 från makrofThe gastrointestinal tract encounters foreign antigens, commensal bacteria and nutrients on a daily basis. Under steady state conditions, a regulatory immune system maintains gut homeostasis. However, disruption of the balance between regulatory components and defeating invading pathogens leads to overshooting inflammatory reactions that can culminate in chronic and relapsing intestinal inflammati

Within clinical diagnostics there is always a need for innovative methods that are rapid, sensitive, and more accurate. In this study two bioanalytical systems have been evaluated for pentraxin 3 (PTX3) detection. PTX3 is a blood biomarker involved in the native immune system that can indicate sepsis, a disease that currently lacks a fast and sensitive analytical method for early detection. Curren

Undersökning av inomhusmiljön i Bostadshus i Kurdistan med förslag på förbättringar Av Zahir Rashid Ibrahim Sammanfattning Den varma sommarsäsongen i Kurdistan är mycket lång och omgivningstemperaturen är cirka 45 ˚C. Byggnader kyls ner med luftkonditioneringssystem på sommaren och värms upp med eldrivna eller oljedrivna värmesystem på vintern. Oljedrivna placeras oftast i vardagsrummet Examination of indoor environment in dwellings in Kurdistan with suggestions on improvements By Zahir Rashid Ibrahim Summary The hot summer season in Kurdistan is very long and the ambient temperature is about 45 ˚C. Buildings are cooled by air conditioning systems in the summer and heated with electric or oil-fired heating systems in winter. Oil-driven are usually placed in the living roo

Vid de flesta processer som innefattar insamlande av data kan det ibland uppstå problem som gör att all data inte samlas in korrekt. När detta händer uppstår det tomma platser i datan där värden saknas. Det finns många sätt att hantera dessa tomma platser och i många fall kan man bortse från dem. Om ett komplett dataset behövs för analys kan så kallade imputationsmetoder användas för att fylla i dImputation of data is the process of filling in missing values in an incomplete data set. Missing data is a common problem in many fields, not least in clinical research. This report aims to evaluate different methods for imputing missing data in health records of dialysis patients. The imputed data will, in a related project, be used to predict hospitalizations of dialysis patients. The hope is t

En liten molekyl med en stor uppgift Alla människor ser olika ut, vi har olika hårfärg, är olika långa och har olika hudfärg. Har du någonsin undrat vad det är som gör dig till dig? Svaret är till stor del dina gener. Vi består av celler och varje cell i din kropp har alla dina gener som behövs för att skapa dig. Man kan likna en gen vid ett recept som cellen använder för att veta hur den ska tiHematopoietic stem cells (HSCs) are of great importance for the body and can be used to treat diseases such as leukemia or autoimmune conditions. To be able to use HSCs more extensively in therapies we need to know more about how they are being regulated, one way to do this is by knocking down genes with RNA interference. In this project we test a new micro RNA (miRNA), called miR30E, to investiga

Immune checkpoint inhibitors have drastically improved the prognosis for several cancer patients, but still the exact underlying mechanism behind cancer immune escape and the role of individual immune cell populations remains poorly understood. Thus, further insights into the level of immune cell infiltration in cancers, their functional role, level of activation and maturity are warranted in orde

Föräldrabalkens 6 kap. 2 a § stadgar att barnets bästa skall vara avgörande för alla beslut i frågor om vårdnad, boende och umgänge.

Previous research has focused on the correlation between CSR and returns, whilst considerably less efforts have been undertaken to investigate whether CSR affects a company’s valuation. Therefore this paper focus on investigating the correlation between these two variables. This is done by comparing valuation multiples of constructed indices consisting of bad and socially responsible companies to

At present there is no health economic model that can fully explain the behaviour of the salaried physician in public health care systems. My purpose is to create a working economic model of the salaried physician in a public health care system. Any model is a simplification of reality and choices have to be made between simplicity and relevance. For this reason I present a sequence of models t

Entrepreneurial universities contribute directly and indirectly to supporting all stages of entrepreneurship. The challenge for entrepreneurial universities is how they can best support academic entrepreneurs through these stages of entrepreneurship. This has led to the creation of different and often ad hoc organizational units within an entrepreneurial university. The organizational challenge fo

A mobile stroke unit (MSU) is an advanced ambulance equipped with specialized technology and trained healthcare personnel to provide on-site diagnosis and treatment for stroke patients. Providing efficient access to healthcare (in a viable way) requires optimizing the placement of MSUs. In this study, we propose a time-efficient method based on a genetic algorithm (GA) to find the most suitable am

Adsorption to microcrystalline cellulose (Avicel) of pure cellobiohydrolase I and II (CBH I and CBH II) from Trichoderma reesei has been studied. Adsorption isotherms of the enzymes were measured at 4 degrees C using CBH I and CBH II alone and in reconstituted equimolar mixtures. Several models (Langmuir, Freundlich, Temkin, Jovanovic) were tested to describe the experimental adsorption isotherms.
