BACKGROUND: Periampullary cancer is a term for cancers arising in or in close proximity to the pancreas. Pancreatic cancer is the 3rd leading cause of cancer death for both sexes and while surgery is the only option for cure, chemotherapy is given in both the adjuvant and palliative settings. The aim of this study was to investigate any sex and gender differences in patients with pancreatic and ot

Two-dimensional (2D) topological insulators have fascinating physical properties which are promising for applications within spintronics. In order to realize spintronic devices working at room temperature, materials with a large nontrivial gap are needed. Bismuthene, a 2D layer of Bi atoms in a honeycomb structure, has recently attracted strong attention because of its record-large nontrivial gap,

Much scientific evidence indicates that the Earth's climate is changing and the world has become more concerned about the global climate. This has encouraged many countries to consider future clean power production with wind power taking an increasing part. In Sweden, the government declared the intention of generating 30 TWh/year from the wind by 2020 instead of 7.1 TWh/year achieved in 2012. Egy

Stroke and in this case cerebral infarction affects 20 million people each year and five million of them die. In Sweden 30-35000 people will be affected and one of three of them will be severely disabled. In addition, one of six will suffer a new stroke within six years. The cause of stroke is usually a vessel in the brain that is blocked, resulting in massive neuronal cell death. Since treatment

Background : In order to increase access to antiretroviral therapy (ART) in HIV-infected children, paediatric HIV care has been introduced in health centres in Ethiopia, where patients are managed by health professionals with limited training. Objective : To compare outcomes of paediatric HIV care in hospital and health centre clinics and to determine risk factors for death and loss to follow-up (

Using kilometric arrays of air Cherenkov telescopes at short wavelengths, intensity interferometry may increase the spatial resolution achieved in optical astronomy by an order of magnitude, enabling images of rapidly rotating hot stars with structures in their circumstellar disks and winds, or mapping out patterns of nonradial pulsations across stellar surfaces. Intensity interferometry (once pio

SH-SY5Y cells stably transfected with TrkA, the nerve growth factor (NGF) receptor, dif

Popular Abstract in Swedish Prostata cancer är en av de vanligast förekommande cancerformerna hos män i västvärlden och den vanligaste förekommande hos män i Sverige. Årligen diagnosticeras i Sverige ungefär 6000 fall och mer än 2000 avlider. Drygt 70% av alla som drabbas är äldre än 70 år medan endast ett fåtal är yngre än 50 år. Sjukdomen ter sig mycket olika hos olika patienter. En del som drabHuman glandular kallikrein 2 (hK2) is a predominantly prostate produced protein with many similarities to prostate-specific antigen (PSA). Just like for PSA elevated levels of hK2 can be found in men with protate cancer. We created an assay where hK2 in serum could reliably and with negligible cross-reactivity with PSA, be measured down to 0.030 ng/mL. The assay measured free hK2 and hK2 complexe

With increasing pressure to get rid of the world’s dependence on fossil fuels to reach the world’s climate goals, the use of alternative fuels for propulsion are needed. This is a challenge for the maritime industry, where ferries have good properties to become renewable by the usage of batteries. Their routes are mostly fixed routes and with good infrastructure established at each stop, fully bat

BACKGROUND: The prevalence of teenage pregnancy in Colombia is higher than the worldwide average. The identification of socio-geographical disparities might help to prioritize public health interventions.AIM: To describe variation in the probability of teenage maternity across geopolitical departments and socio-geographical intersectional strata in Colombia.METHODS: A cross-sectional study based o

Background: Adolescent depression is a common mental health problem and there is an urgent need for effective and accessible treatments. Internet-based interventions solve many obstacles for seeking and receiving treatment, thus increasing access to effective treatments. Internet-based cognitive behavioural therapy (ICBT) for adolescent depression has demonstrated efficacy in previous trials. In o

Understanding the dissolution kinetics is important in the experimental determination of solubility, the efficiency of extractions, the rate of reactions and in general any heterogeneous process. Despite the extensive use of supercritical fluids, studies regarding the dissolution kinetics of compounds in supercritical carbon dioxide (scCO2) using analytical methods are limited in the literature. S

I denna rapport analyseras hur dimensioneringen av Rectiverter och UPS systemens storlek är anpassade för driftsplatsernas faktiska elförbrukning och vilka potentiella lösningar som finns för att effektivisera användandet av systemen för att minska elförbrukningen. Effektiviserandet av driftplatsernas system kommer att leda till en kostnadseffektivare anläggning. För svenska lågspänningsanläggningThis report analyzes how the size of Rectiverter and UPS systems is tailored to the actual electricity consumption at operational sites and explores potential solutions to optimize the usage of these systems in order to reduce electricity consumption. Optimizing the operational sites' systems will result in a more cost-effective facility. In Swedish low-voltage installations, a standard has be

Do birds have a sixth sense? Many animals have been shown to possess the ability to sense polarized light, but this ability in birds has been a topic for debate. In this study captive male zebra finches were used in order to determine if they could distinguish different angles of polarized light. Polarized light is the direction of the angle of the light waves, thus two separate light sources c

This thesis aims at comparing the differences between Chinese welfare system and Swedish welfare system in respects of maternity insurance, parental leave and childcare. The reason comparing welfare system in these specific aspects is because they have intense relations with the mothers’ and children’s benefits. They also influence the mothers’ will of pregnancy. Selecting these two countries as t

Berggrunden i sydvästra Sverige består av bergarter som deformerades och metamorfoserades under den Svekonorvegiska kontinent kollisionshändelsen. Den så kallade ”Sveconorwegian Frontal Deformation Zone” norr om Vättern och Protoginzonen söder därom anses utgöra den östligaste gränsen för Svekonorvegisk omarbetning. Söder om Vättern är Protoginzonen en 20-30 km bred N-S deformationszon. FortsättniThe bedrock in the southwest of Sweden was deformed and metamorphosed during the Sveconorwegian orogeny. The Sveconorwegian Frontal Deformation Zone north of the lake Vättern and the Protogine Zone south of the lake is regarded as the eastmost boundary of Sveconorwegian reworking. South of lake Vättern the Protogine Zone is 20-30 km wide made up of a system of discrete ductile (and locally brittle
