The aim of this thesis is to compare the occurrence of wetlands in the early 1800’s with the contemporary occurrence. The findings will be presented from three angles: the total wetland area, presence of different wetland types, and spatial distribution of the wetlands. To assess this change over ti

Undersökning av två ytmarkörers uttryck i mantelcellslymfomceller öppnar möjligheter för målinriktad cancerbehandling. Proteinerna CD44 och CD69 tillverkas i högre utsträckning i en minoritet av cancercellerna i mantelcellslymfom. Dessa cancerceller är kända för att vara svårbehandlade och tros ligga bakom den höga andel återfall som är förknippad med sjukdomen. Genom att undersöka dessa proteineThe B-cell lymphoma (BCL) subtype, mantle cell lymphoma (MCL) is a lymphoid malignancy associated with high risk of relapses and an overall poor prognosis. The relapses are believed to be the result of a treatment resistant sub-population harbouring stem cell like properties. One way to isolate and identify such cells is through analysis of the side population (SP) by staining with Hoechst 33342.

Gender equality and empowerment of women and girls were presented at the Sustainable Development Goals (SDG5) by the United Nations. It has been realized that empowerment of women plays a crucial role in development. This study examines the empowerment process of rural migrant women in China. It first describes the registration house system called hukou and general gender roles in China. This rese

NDVI(Normalized Difference Vegetation Index) was introduced in 1974. Despite its limitations, it has been under use for monitoring bio-physical and cultural landscapes from satellite. The present study employed MODIS based NDVI to examine trends of greenness and its link with LULC (land use/land cover) change and rainfall in Addis Ababa and its surrounding (covering 1,217 sq km) over a period of 1

Idag når vi i Sverige inte upp till miljömålet ”Grundvatten av god kvalitet”, en av orsakerna är bristande grundvattenkunskaper i samhället. Kontrollen av föroreningar är otillräcklig och det har under den senaste tiden uppmärksammats att vi har brist på vatten i stora delar av landet. På Revingehed ca 2 mil öster om Lund finns en provpumpningsanläggning som används för utbildning av framtida grunSweden do not meet the environmental objective "Good quality groundwater", one of the reasons is the poor general understanding of groundwater. The control of pollutions is insufficient and it has recently been noted that the storage of water in large areas of the country is inadequate. At Revingehed about 2 kilometers east of Lund, there are several pump wells that is used for education

According to the United Nations, half of humanity now lives in cities. In recent years, many countries have seen a rise in the number of and intensity of heavy rainfall events due to the effects of climate change. The consequences of urban flooding in such a context can vary between just causing mild discomfort to tremendous devastation. Building cities that can resist flood is quickly becoming an

Samhällets minoritetsgrupper har historiskt sett varit utsatta för misskreditering och diskriminering av olika slag. I denna uppsats har speciellt fokus lagts på den minoritetsgrupp som utgörs av de tusentals afghanska ungdomar som sökt eller söker asyl i Sverige. Syftet med uppsatsen har varit att studera hur individer i denna grupp upplever och hanterar stigma i sin vardag. Det empiriska underla

I takt med att miljö och hållbarhet blir alltmer prioriterade frågor för samhället kommer marknaden för biobränslen och energi producerad från biobränslen öka. Genom ökad konkurrens bland energiproducenter skapas ett större krav på lagerhantering som är en grundläggande kompetens för företag. Lager och lagerhanteringen har direkt påverkan på resultatet och därmed hur konkurrenskraftigt företaget ä

This thesis considers the problem of improving the performance of observed time difference of arrival (OTDOA) based positioning for Narrowband Internet of Things (NB-IoT). A new iterative low-complexity algorithm based on expectation maximization successive interference cancellation (EM-SIC) is presented. The algorithm tackles the near-far problem by using an iterative SIC, where for each received

The migration debate is discussed globally in today’s society, and countries have chosen to deal with placement of migration in different ways. Australia has demonstrated a unique way of handling migrants through their two policies. One of them places and processes migrants on the islands of Manus and Nauru in the last decade instead of conducting this vetting process on their own soil. This offsh

The aim of this study is to investigate human behavior during the pre-movement phase of building evacuation and determine how pre-movement time varies between different building types and types of alarms. Unannounced videorecorded evacuation experiments from earlier studies were examined, which resulted in 2 486 individual pre-movement times divided amongst six different building types. The parts

In several regions of today's Europe there is an increased activity for socio-political self-government or total independence. The European Free Alliance (EFA) is a transnational European party that represent many of these regions at a supranational level. As the party brings together regions with strong national and regional identities and constitutes an ideological platform for meetings betw

Framtagning av nya produkter som är konkurrenskraftiga ur ett helhetsperspektiv kräver att flera olika avdelningar och kompetenser samverkar. Examensarbetet studerar hur detta kan genomföras på bästa sätt. Begreppet tvärfunktionell samverkan definieras som: Hur väl olika funktioner arbetar mot ett gemensamt mål. Projektet undersöker hur svenska företag ser på tvärfunktionell samverkan, vilka konkNew product development requires the cooperation of several departments and competences to create competitive products from a holistic perspective. This master thesis studies how Swedish companies’ view cross-functional cooperation, the competitive advantages with cross-functional cooperation and examine the prerequisites to achieve well-functioning cross-functional cooperation.

I en teoretisk studie har användbarheten av thermosyphoner för att förbättra säkerheten och effektiviseringen av kemiska reaktorer. Thermosyphoner är en simpel form av en ”heat pipe”, ett ihåligt och slutet rör som är delvis fyllt av en fluid. Om röret värms upp till fluidens kokpunkt inleds en inre fasomvandling vilket används för att förbättra rörets värmeledningsförmåga. Tre simuleringsmodellerIn a theoretical study the use of thermosyphons to improve the safety and efficiency of chem-ical reactors have been evaluated. Thermosyphons is a simple form of a “heat pipe”, a hollow and closed tube that’s partially filled with a fluid. When the pipe is heated up to the boiling temperature of the fluid within a phase change is initiated. The phase-change is used to im-prove the thermal conducti

In this master thesis it's concluded that Swedish municipalities performs various traffic data collections in recurring measurement points annually and beside those complementing measurements are done at additional areas of interest. The study shows that most often traditional measurement methods, like pneumatic tubes, are used since they are considered reliable and accurate. Pneumatic tubes,

Democratic transitions have been associated with a high level of economic development and good economic performance according to modernization theory. However, until now no consensus has been reached about the specific form of the relationship. Thus, this study attempts to examine whether these suggested linkages hold evidence for the case example of Latin America by testing a linear as well as a

The Pacific Island countries face a host of unique and urgent development challenges that have historically provided the impetus for pursuing various forms of regionalism. This study seeks to shed new light on these processes by examining how the low levels of institutional and governance capacity of regional actors has influenced the success of institutional development strategies within the broa
