The sperm whale (Physeter macrocephalus) is a cosmopolitan species with a broad distribution that ranges from the tropics to the poles. Males are known to migrate between nutrient-rich high latitude waters and low latitude breeding grounds. In the North Atlantic, large males are found up to the southern limits of the ice edge. However, their seasonal distribution patterns remain poorly known in th

Ett alternativ för att studera immunceller i cellkulturer utan djurprodukter Cancer är ett samlingsnamn för en rad olika sjukdomar som kan uppstå var som helst i människokroppen. Tillståndet kännetecknas av att tumörer bildas i en viss kroppsdel som kan spridas till andra delar. Tumörer är komplexa strukturer som inte bara innehåller cancerceller. Cancercellerna i en tumör omringas av en så-kallaThe use of cancer cell cultures, including immune cells, is essential in cancer research for developing immunotherapies in pre-clinical investigations. However, so far, a large number of animal-derived products are utilised in cell culturing, where experimental variations and reproducibility problems have been reported. Most studies have also only investigated the differentiation of monocytes into

Beginning in the late 20th century, public libraries in Sweden have been offering its patrons the opportunity to check out films just as they would books. Taking place over the last decade, however, the methods by which we predominantly consume films have gone through major changes – mainly caused by our increased digital presence and, more importantly, the extensive development of popular streami

Purpose: investigate in which ways sustainable development in Swedish schools is constructed as a wicked problem. Research Question: How is sustainable development constructed as a wicked problem in Swedish educational contexts? Methodology: A qualitative study approach was implemented where 20 semi-structured interviews were used for data collection. The data analysis followed the process of sort

I studien undersöktes associativ språkinlärning via Virtual Reality (VR) och jämfördes sedan med en mer traditionell ordinlärning via en datorskärm, för att se om det förekom någon skillnad i inlärningen mellan dessa. Syfte. Studien syftade till att undersöka om inlärning av ett nytt språk gynnas av associativ inlärning med flera av våra sinnen genom VR. Vår hypotes var att språkinlärning kan gynThe study examined associative language learning through Virtual Reality (VR) and then compared it to more traditional word learning through a computer screen, in order to see if there was any difference in learning between these two. Purpose. The aim of this study to investigate whether learning a new language benefits from associative learning, with several of our senses, through VR. Our hypoth

There is a growing demand for environmentally friendly food packaging. Studies and trends show that the modern consumers are willing to pay more money for food products if the packaging has lower carbon footprint. Furthermore, to be competitive, food packaging must be both visually striking and user friendly. It needs to differentiate from other multipacks and have enough shelf impact to stand out

Behovet av avancerad rening genom till exempel ozonering eller aktivt kol på avloppsrenings-verk blir tydligare i världen som följd av höga uppmätta nivåer av läkemedelsrester i recipienter. I länder som Schweiz är implementeringen redan idag lagstadgad och också i Sverige förväntas inom en överskådlig framtid krav införas på avlägsning av organiska mikroföreoreningar från avloppsvatten. I dagslägThe need for advanced wastewater treatment using for example ozonation or activated carbon is becoming exceedingly apparent because of high measured concentrations of pharmaceutical res-idues in recipients all over the world. In Switzerland for example there is legal requirements for the implementation of advanced treatment and within the foreseeable future also in Sweden the demands on the remova

Bakgrund: Manligt kön och hög ålder har visat sig utgöra riskfaktorer att återinläggas på IVA. Att implementera uppföljande verksamhet efter utskrivning, såsom PIG-team, kan bidra till att identifiera patienter som riskerar att försämras i sitt sjukdomstillstånd eller återinläggas på IVA. Tillämpandet av bedömningsinstrumentet NEWS har visat sig kunna identifiera patienter som löper risk för oplanBackground: Male sex and older age have been described as risk factors for readmission to the Intensive Care Unit [ICU]. The implementation of PIG-team can help to identify patients who are at risk for clinical deterioration or being readmitted to the Intensive Care Unit. The usage of National Early Warning Score [NEWS] has been proven to effectively discriminate patients who are at risk for unpla

Background: Gastrectomy, specifically the removal of the acid-producing part of the stomach (fundectomy), is known to cause osteopenia. This effect has been ascribed to the elimination of a hypothetical osteotropic peptide hormone, presumably produced in the oxyntic mucosa. Since osteopenia is due to a disturbed balance between bone formation and resorption, we assessed the effect of gastrectomy o

Clay minerals cannot only give information on sedimentary depositional environment but also the climate regime under which sediment was weathered. The successions of non-marine to marine Middle and Late Jurassic strata of the East European Platform show upwards increasing contents of smectite and decreasing contents of kaolinite. There is also an increasing smectite vs. kaolinite ratio laterally,

A new technique for two-dimensional temperature measurements of burning surfaces is presented. Laser-induced phosphorescence from a thermographic phosphor material applied to a surface of investigation was measured with a fast framing camera. The phosphor was excited by the 4th harmomic from a pulsed Nd:YAG operating at 10 Hz. The phosphorescence images measured by eight consecutively gated CCD de

BACKGROUND: The common ABO allele sequences are known, but little or no genetic information is available on the rare but important A subgroups. STUDY DESIGN AND METHODS: Blood group ABO polymorphism was analyzed in genomic DNA from 45 rare subgroup A individuals by sequence-specific primer polymerase chain reaction and amplified fragment length polymorphism investigating exons VI and VII in the AB

Popular Abstract in Swedish I denna avhandling studeras den akuta inflammatoriska reaktionen i huden. Akut inflammation beskrevs redan under romersk tid av Aulus Cornelius Celsus. Han karakteriserade denna reaktion med rodnad, svullnad, värme och smärta. Fysiologiskt består akut inflammation av vidgning av små blodkärl (vasodilatation) som ger upphov till rodnad samt av läckage av plasmaproteiner This thesis examines the microvascular inflammatory response in the skin. The microvascular response includes vasodilatation and plasma exudation. In the first three studies, the combined response was measured in guinea pig skin with a technique based on detection of radiolabelled protein. Transferrin was labelled in vivo by injection of 113mIn and the conversion electrons detected over the skin u

Objective: To monitor changes in serum concentrations of cartilage oligomeric matrix protein (COMP) during a 24-h period to determine any diurnal variation, and to estimate the half life of COMP in the circulation in patients with symptomatic knee osteoarthritis and in those with rheumatoid arthritis. Methods: Serum samples were drawn every 4 h (7 samples/patient over 24 h) in 10 patients with kne

OBJECTIVES. To compare family physicians' reported practice habits on hypertension in Sweden and Minnesota, and to assess to what extent different national guidelines account for differences. DESIGN. Random samples of family physicians were selected for telephone interviews on their practice of hypertension. SETTING. Primary care in southern Sweden and in Minnesota. SUBJECTS. Family medicine speci

BACKGROUND AND OBJECTIVES: Amerindians are blood group O, but the distribution of the various O alleles is unknown. Their ABO genotypes were compared with samples from other Brazilian ethnic groups. MATERIALS AND METHODS: Genomic DNA was examined by PCR-RFLP analysis, PCR-SSP and direct sequencing. RESULTS: An unusual allele distribution was found, with 91% of the O alleles being O1variant. Almost

Forestry in Sweden suffers from browsing damage caused by large herbivores, mainly moose (Alces alces) and roe deer (Capreolus capreolus). Silviculture affects the availability of forage for these animals, and thus the browsing pressure. A step towards modeling the response of trees or to predict browsing damage is to gain more knowledge on the availability of food in forest stands. Individual gap

The antithrombotic effect of bovine activated protein C (bAPC) given with or without bovine protein S (bPS) was investigated in a rat model of deep arterial injury. A segment of the left common carotid artery was isolated between vascular clamps and opened longitudinally. An endarterectomy was performed and the arteriotomy was closed with a running suture, whereafter the vessel was reperfused by r

Background: Funding organisations and research ethics committees (RECs) should play a part in strengthening attention to gender equality in clinical research. In the research policy of European Union (EU), funding measures have been taken to realise this, but such measures are lacking in the EU policy regarding RECs. Objective: To explore how RECs in Austria, Germany, Ireland, The Netherlands and
