This master thesis is commissioned by the company Haldex Brake Products AB based in Landskrona. The company is acting on the road vehicle market. Amongst other products the company produces disc brakes for the heavy road vehicle industry. Disc brakes developed by Haldex, based on the sliding caliper principle, are during certain circumstances experiencing problems with malfunction of the brake due
Neurogenesis in the adult mammalian brain is well studied, in the two main regions subventricular zone (SVZ) and subgranular zone (SGZ), under different physiological and pathological condition. Recent studies also revealed newly formed neurons in other parts of the brain including the hypothalamus. However, how robust neurogensis in this area is, is still unclear. In this study we used a novel re
The purpose of the study was to investigate how companies can harness the power of social media by utilizing Social CRM. It was investigated how integrating social media channels into existing Client Relationship Management platforms can influence customer service and customer loyalty. A mixture of both qualitative and quantitative research methods with an abductive approach was used. The researc
Objectives Exposure to diisocyanates is a well known occupational hazard. The objective of this study was to determine the possibility of an association between low exposure to toluene diisocyanate (TDI) (airborne isocyanates and biomarkers of isocyanates in plasma and urine) and symptoms of the eyes and upper and lower airways. Methods Altogether 136 workers occupationally exposed to TDI and 118
The freeze-drying tolerance of Pseudomonas chlororaphis, an antifungal bacterium used as biocontrol agent was investigated. P. chlororaphis is freeze-drying sensitive and the viability drops more than 3 log units in the absence of protective freeze-drying medium. Of the freeze-drying media tested, lactose, sucrose, trehalose, glutamate, sucrose with glutamate, skimmed milk, and skimmed milk with t
Cardiovascular nursing (CVN) is rapidly developing and has accumulated a large amount of evidence to support interventions aimed at reducing suffering and hastening recovery. However, knowledge of the extent and content of CVN training in Sweden is lacking. The aim of this study was therefore to identify and describe CVN in the Swedish RN education as well as in higher education, with reference to
Rhesus Rhadinovirus (RRV) is currently the closest known, fully sequenced homolog of human Kaposi's sarcoma-associated herpesvirus (KSHV). Both these viruses encode complement inhibitors: KSHV-complement control protein (KCP) and RRV-complement control protein (RCP). Previously we characterized in detail the functional properties of KCP as complement inhibitor. Herein, we performed comparative ana
Objectives: To develop an automated tool for the analysis of electrocardiograms (ECG) with respect to changes that make the patient a candidate for reperfusion therapy. An additional aim was to assess the influence of the tool on the ECG classifications of three interns. Methods and Results: An artificial neural network was trained to interpret ECGs regarding changes making the patient a candi
Background. The question is debated on whether maternal hypothyroidism or use of thyroxin in early pregnancy affects the risk for infant congenital malformations. Objectives. To expand the previously published study on maternal thyroxin use in early pregnancy and the risk for congenital malformations. Methods. Data from the Swedish Medical Birth Register were used for the years 1996-2011 and infan
CO(2)-laser C-fibre evoked cortical potentials (LCEPs) is a potentially useful animal model for studies of pain mechanisms. A potential confounding factor when assessing analgesic effects of systemically administered drugs using LCEP is sedation. This study aims to clarify: 1) the relation between level of anaesthesia and magnitude of LCEP, 2) the effects of a sedative and an analgesic on LCEP and
Background and purpose The remodeling of morselized bone grafts in revision surgery can be enhanced by an anabolic substance such as a bone morphogenetic protein (BMP). On the other hand, BMPs boost catabolism and might cause a premature resorption, both of the graft and of the new-formed bone. Bisphosphonates inactivate osteoclasts and can be used to control the resorption. We studied a combinati
Background: Motion sickness (MS) is a common complaint during most modes of travel. Several medications can be used to treat MS but are often accompanied by side-effects. Objective: To assess whether performing the Valsalva manoeuvre can influence the subjective feeling of MS in healthy individuals. Methods: We included 16 healthy participants (4 female) that underwent two sessions of MS induction
A key aspect of imperialism, colonialism, and capitalism is frontier-making. Frontiers are essential for ambitions of appropriation and extraction. This paper explores the discursive practices of frontier-making in Scandinavia including the conceptualization of parts of this region as empty space and ripe for exploitation, as wild, unruly and in need of domestication. These regions have historical
Trots att kunskaperna om och intresset för smärta och smärtlindring har ökat de senaste åren drabbas fortfarande många patienter en inadekvat smärtlindring och många patienter förväntar sig smärta postoperativt. Syftet med denna studie var att undersöka kvinnor i olika åldrar avseende förväntningar och upplevelser av postoperativ smärta och smärtlindring samt hur stor betydelse den preoperativa in
Nickel phosphide is a valuable material in high-temperature brazing and joining applications, offering excellent thermal stability for temperatures up to 400°C. Nickel phosphide is used as powder form for joining applications and therefore it is imperative to study the formation as well as interaction of Ni2P particles with Brazing with nickel-chromium-based fillers is widely used to join stainles
Trimethylolpropane (TMP) is an important industrial chemical used to produce various value-added chemicals and polymers. In this study, both biobased butyraldehyde and formaldehyde were produced by the incomplete oxidation of bio-1-butanol and biomethanol, respectively, and were then used to produce a biobased TMP. High selective incomplete oxidation of primary alcohol to aldehyde is a challenging
Over geologic time, biocalcification – the process by which marine organisms make calcium carbonate (CaCO3) – has reshaped climates, ocean life, and seawater chemistry. In particular, the evolution of coccolithophores, the largest group of nannoplankton and today’s most productive calcifiers, transformed ocean environments and the carbon cycle. Their origins, however, remain enigmatic. This is par
