I dagens samhälle spelar sociala medier en allt större roll i vår dagliga kommunikation. Instagram, som är en bildapplikation, gör det möjligt för användare att publicera och sprida bilder via sin mobil. Det laddas upp ca 4,5 miljoner bilder varje dag på Instagram och tjänsten har ungefär 30 miljoner användare. Syftet med uppsatsen är att undersöka hur sociala medier har gått från att vara textbas

This thesis handles the problem with fluid selection in organic Rankine cycles application. The main goal was to write a program that based on user defined variables finds the maximum power output from a range of fluids. The program was programmed in Matlab and is coupled with REFPROP that return the fluids characteristics as enthalpy and entropy etc. The program is preloaded with the fluids foun

The study aims to examine the impact of Expressive Suppression (ES), on Working Memory (WM) performance when exposed to mild pain reaction causing physiological activation. Performance measures are obtained to discriminate between three groups having their hands in warm water, cold water, and cold water and implementing ES. As a measure of WM performance, this study used a WM 2-back task intersper

This paper focuses on the distinction between the private and the public in relation to violence and sexual crimes against women in relationships and intimate relationships. Historically, violence and sexual abuse in intimate relationships has been placed in the private sphere away from the law. Concepts such as "family matter" and "family violence" has expressed that a certain

The main topic of this thesis is the storage location assignment problem, which can also be seen as a traveling salesman problem. The objective is to find the shortest path between items to be picked at a medium-sized warehouse. Orders come in batches consisting of items that will be assembled in-house. Therefore, it is essential to pick up all the items contained in the batch before they are drop

The role of the artist is influenced by the development of society and is understood in its context hereby. My interest is to study tendencies as they reveal themselves in various ways, in the expressions by different actors in the art education, art community and art fields. My material is articles in media, in magazines, newspapers and also interviews concerning the ideas of the artist role. The

This work experimentally tests and numerically investigates the heat transfer augmentation, the flow characteristics and the overall thermal performance of truncated ribs in a rectangular channel with an aspect ratio of 1:4 designed by using the fractal theory. The liquid crystal thermography (LCT) method in steady-state is adopted and the three-dimensional CFD numerical simulations with an establ

The continental silicon (Si) cycle, including terrestrial and freshwater ecosystems (lakes, rivers, estuaries), acts as a filter and modulates the amount of Si transported to the oceans. In order to link the variation in the terrestrial Si cycle to aquatic ecosystems, knowledge on changes in vegetation cover, soil disturbance and the impact of human activity are required. This study on varved lake

Patients undergoing surgical aortic valve replacement (SAVR) are at high risk for atrial fibrillation (AF) and stroke after surgery. There is an unmet clinical need to improve stroke prevention in this patient population. The LAA-CLOSURE trial aims to assess the efficacy and safety of prophylactic surgical closure of the left atrial appendage for stroke and cardiovascular death prevention in patie

The ability to predict fire behaviour of materials is of key interest to building materials industry. Themain reason for it is expensive fire testing and certification costs borne by the manufacturers to bring a finished product to market. Failure in a fire test leads to increased expenses in the productdevelopment cycle leading to delayed realization of profits and low cost competitiveness in the

Kvantitativ analys är en teknik som syftar till att förstå komplexa system genom att använda matematisk och statistisk modellering. Det är en viktig del av dagens finansiella system och innebär bland annat att modellera den slumpmässiga utvecklingen av finansiella tillgångar, och för att förutspå verkliga händelser som till exempel förändring av riksbankens styrränta. En mycket vanlig metod som anDiffusion processes are the most commonly used models in mathematical finance, and are used extensively not only by academics but also practitioners. Nowadays a wide range of models, that can capture many of the effects observed in financial markets, are available. A very important task is to calibrate the models to observed market data and to achieve a good fit, since a slight misspecification ca

Human C4b-binding protein (C4BP) is a regulator of the classical pathway of the complement system. It appears in two forms in plasma, as free protein and in a noncovalent complex with the vitamin K-dependent coagulation protein, protein S. In the electron microscope C4BP has a spider-like structure with a central core and seven extended tentacles, each of which has a binding site for C4b, although

OBJECTIVES: Pectus excavatum (PE) can cause both physical and psychosocial symptoms and affect patients' health-related quality of life. Previous international studies have shown that the Nuss procedure increases both self-esteem and body image. The aim of the study was to evaluate the health-related quality of life in patients who have undergone the Nuss procedure for PE. METHODS: The study had a

Evaluation of a complex healthcare intervention should include careful exploration of the mechanisms through which it brings about change. This paper describes a qualitative evaluation of the Redesigning Daily Occupations (ReDO®-10) programme as it was implemented for the first time with women with stress-related issues in a primary care setting in Ireland. The ReDO®-10 is a 10-week group interven

Background: Attention deficit hyperactivity disorder (ADHD) in children is associated with hyperactivity and impulsivity, attention problems, and difficulties with social interactions. Pharmacological treatment may alleviate the symptoms of ADHD but this rarely solves difficulties with social interactions. Children with ADHD may benefit from interventions designed to improve their social skills.We

Level lifetime and side-feeding time measurements were performed on the excited states of the normally deformed bands of Y83 using the Doppler-shift attenuation method (DSAM). The high spin states of Y83 were populated using the fusion-evaporation reaction Ni58(S32,α3p)Y83 at 135 MeV. Twenty-two level lifetime and side-feeding times were determined in most of the cases by comparing the line shapes

Background and Objective: Waste in clinical trials remains rife. We developed an economic model to predict the cost of trials based on input costs, duration, power, number of sites, recruitment eligibility and consenting rates. Methods: We parameterised the model for three proxy placebo-controlled surgical trials using data from a systematic review, a bespoke cost survey, and from the literature.

The use of a semi-empirical alternative to the standard Washburn equation for the interpretation of raw mercury porosimetry data has been advocated. The alternative expression takes account of variations in both mercury contact angle and surface tension with pore size, for both advancing and retreating mercury meniscii. The semi-empirical equation presented was ultimately derived from electron mic

Introduction: The addition of hyperthermic intraperitoneal chemotherapy (HIPEC) to interval cytoreductive surgery (CRS) improves recurrence-free (RFS) and overall survival (OS) in patients with FIGO stage III ovarian cancer. We evaluated the effect of HIPEC on patient's health-related quality of life (HRQoL) in the OVHIPEC trial. Materials and methods: OVHIPEC was a multicentre, open-label, random
