We present a blow-up criterion for the periodic Camassa-Holm equation. The condition obtained for blow-up uses two of the conservation laws associated with the equation and improves upon some recent results.

To discover whether islet sympathetic nerves are damaged during the autoimmune destruction of islet B-cells, we immunostained sections of pancreas from BioBreeder (BB) diabetic rats, using antibodies against vesicular monoamine transporter 2 (VMAT2), a marker of sympathetic nerve terminals. We found a marked decrease in the VMAT2-positive fiber area in the islets of BB rats that had been diabetic

In several twin studies the relative contribution of genetic factors for personality traits has amounted to figures between 40 and 60%. In the present study we investigated to which degree polymorphisms in the 5-HTT and AP-2 beta genes are implicated in the neural processes involved in the formation of Temperament and Character traits, as estimated by Cloninger's TCI. Considering the background of

Multiple genetic loci confer susceptibility to breast and ovarian cancers. We have previously developed a model (BOADICEA) under which susceptibility to breast cancer is explained by mutations in BRCA1 and BRCA2, as well as by the joint multiplicative effects of many genes ( polygenic component). We have now updated BOADICEA using additional family data from two UK population-based studies of brea

The aim of our retrospective study was to determine the extent to which diffusion- and perfusion- weighted MRI combined with conventional MRI could be helpful in the evaluation of intensive care unit (ICU) patients who have unknown or unclear cerebral pathology underlying a serious clinical condition. Twenty-one ICU patients with disparity between the findings on brain CT scan and their clinical s

The development of bacterial vaginosis (BV) among women of childbearing age and the resulting quantitative and qualitative shift from normally occurring lactobacilli in the vagina to a mixture of mainly anaerobic bacteria is a microbiological and immunological enigma that so far has precluded the formulation of a unifying generally accepted theory on the aetiology and clinical course of BV This cr

This paper studies international trade in the case of Portugal as a small and peripheral economy in Europe and its trade integration with the European Union. The purpose of the paper is to find if Portugal’s EU accession in 1986 increased trade with EU members. Common for research on trade effects of EU integration is that ascending countries see significant increases in trade. Theory also suggest

Klimatförändringar är idag ett faktum och påverkar både människor och vår omgivning världen över. I Lund i södra Sverige beräknas både mängden och frekvensen av extrema skyfall att öka i framtiden, som konsekvenser av klimatförändringarna, vilket skapar stor risk för översvämningar. Samtidigt växer befolkningen och fler bostäder behövs men när nya stadsdelar byggs så finns det risk för att permeabThe consequences of climate change affect our environment as well as humanity all over the world. For the city of Lund in southern Sweden, climate change consequences are seen as an increase of both intensity and frequency of extreme rain events, which causes an extensive risk for pluvial flooding. Simultaneously, the population and need for housing are growing. When building new districts, the pe

In modern history, Sweden has experienced two major financial crises: the early 1990s and the global financial crisis in 2008. During the last decades, there has been an increased global focus on regulating and supervising banks, where Basel III is the leading framework. Today, one of the most debated issues within the global economy is Covid-19. It is uncertain how the pandemic will affect countr

In a modern-day circular economy context, there is a dire need for companies all over the world to change and adapt their business model from linear to circular. This thesis is thus dedicated to deepening the understanding of business models in circular transition, by looking at effects on the specific business model components: value proposition, value creation and delivery, and value capture (as

This thesis aims to provide information regarding which critical success factors that are beneficial for small and medium enterprises when implementing Robotic Process Automation. It has been done by identifying 11 critical success factors from 14 academic research articles treating Critical Success Factor’s in Customer Relationship Management and Enterprise Resource Planner implementations. The 1

Workplace surveillance is a necessity which was prompt by the development of information communication technologies that offered huge opportunities to employers to monitor their employees at work and even out of work which cause strict concerns for the privacy of employees. The present thesis examines such concerns of employees arising out of workplace surveillance. The legal protection of privacy

Bakgrund: Att intubera prehospitalt är oftast svårare än intrahospitalt. Prehospitalt behövs hänsyn tas till patientens placering och bristande tillgång till utrustning. Förloras luftvägen oavsett trauma leder det till en snabb förlust av livet. Syftet är att belysa anestesisjuksköterskans kompetensområde och hens upplevelse av att arbeta prehospitalt. Metod: En kvalitativ ansats har använts till

Within international human rights law, the prohibition of torture is absolute and uncontroversial. However, despite considerable efforts to end it, torture remains a pervasive problem all over the world, in part due to the widespread impunity for such acts. Many have hence identified universal jurisdiction as one of the ways whereby accountability for torture may be enhanced. The present thesis ex

The importance of well-being has gained wide-spread recognition within entrepreneurial research and at the same time entrepreneurial coach relationships have received more attention in academia. There is however, a lack of understanding on the influence of coaches on the well-being of entrepreneurs. This study seeks to contribute to academic literature by focusing on the subject of accelerator coa

Detta examensarbete undersöker den nuvarande situationen för cyklande barn i Sverige. Den undersöker ett internationellt och historiskt perspektiv, vilket ger jämförbar information om säkerheten för cyklande barn i andra samhällen. Variationer över tiden i totalt cyklad längd studeras och dess inverkan på säkerheten är noga övervägd. Minskade cykelnivåer visar sig vara en avgörande faktor för säkeThis master thesis investigates the current safety situation for biking children in Sweden. It investigates an international and a historical perspective, which gives comparable information about bike safety for children in other societies. Alterations over time in total biked length is studied and its impact on the safety are considered. Reduction in levels of biking are found to be a vital facto

While carbon emissions hit an all-time high in 2019 and are expected to grow, it is important to explore strategies for reducing emissions and mitigating climate change. A potential focus for curbing emissions is the flying sector, since air travel is one of the most carbon-intensive activities an individual can engage in. Among air travelers, frequent flyers yield the highest potential for saving

Syftet med uppsatsen är att utforska och beskriva hur antagonistisk marknadsföring används i företagens reklamfilmer, samt analysera konsumentreaktioner som denna typ av marknadsföring väcker bland berörda brand communities med hjälp av det teoretiska perspektivet. Uppsatsen utgår från ett socialt konstruktionistiskt vetenskapligt förhållningssätt, med en abduktiv forskningsansats. Den empiriska

Household wealth is the gold standard of measuring poverty, however, poor individuals are not necessarily found in poor households. If household wealth is used in a context where the household members are not equally poor, poverty statistics measured on a household level might be wrong. This research aims to test the proposition ‘poor individuals are mainly found in poor households’. The relations
