Alternative fuels have been proposed as a means for future energy-secure and environmentally sustainable transportation. This review and benchmarking show that several of the alternative fuels (e.g. methanol, ethanol, higher alcohols, RME, HVO, DME, and biogas/CNG) work well with several different engine concepts such as conventional SI, DICI, and dual fuel, and with the emerging concepts HCCI, RC

Background. Anaemia in haemodialysis patients can be effectively treated with erythropoietin. We investigated whether subcutaneous (SC) epoetin β administered once weekly was as effective as the same weekly dosage given in two to three divided doses. Methods. One hundred and fifty-eight patients (delivered Kt/V >1.0, where K=dialyser-renal urea clearance, t=dialysis time and V=filtration volume, o

The selective mobilization of fatty acids from white fat cells depends on their molecular structure, in particular the degree of unsaturation. The present study was designed to examine if the release of fatty acids by hormone-sensitive lipase (HSL) in vitro i) is influenced by the amount of unsaturation, ii) depends on the temperature, and iii) could explain the selective pattern of fatty acid mob

BACKGROUND AND PURPOSE: Radiotherapy treatment planning algorithms continue to develop and current planning systems typically offer simpler, but faster, algorithms, which may be 2, 2.5 or 3D in modelling scatter, but which do not model electron transport (type a) and more accurate algorithms which aim to be fully 3D, i.e. which model 3D scatter and also model electron transport (type b). A range o

Air Traffic Controllers (ATCOs) are essential sharp-end workers in the increasingly complex Air Traffic Management (ATM) system that the European ATM network has become. This research is based on an event that occurs many times daily in the Copenhagen Area Control Center (ACC). ATCOs choose whether or not to split sectors. To cope with workload, which is constituted by variation in traffic volume

Estimates of relevant source area of pollen (RSAP) and relative pollen productivity (PPE) are critical parameters for quantitative reconstructions of past vegetation and land cover. This study provides estimates for PPE relative to Poaceae for ten taxa, characterizing the cultural landscape of south Estonia and the RSAP for 40 lakes with an average radius of approximately 100 m (22-274 m, average

The subject of the thesis is the psychê, a Greek word whose closest equivalent is the Swedish “själ”, the English “soul”, the French “âme” and the German “Seele”. The meanings of these words are far from being the same. What is more, the Greek psychê has shifting meanings, both synchronically and diachronically speaking. We are faced with two problems: What does the word psychê designate and how i

OBJECTIVE. Screening examination for retinopathy of prematurity is distressing and painful. The aim of the present study was to investigate whether a Newborn Individualized Developmental Care and Assessment Program intervention during a retinopathy of prematurity examination results in less adverse behavioral, pain, and stress responses as compared with standard care. METHODS. The first 2 eye exam

Bisphosphonates (BP) prevent, reduce, and delay cancer-related skeletal complications in patients, and have substantially decreased the prevalence of such events since their introduction. Today, a broad range of BP with differences in potency, efficacy, dosing, and administration as well as approved indications is available. In addition, results of clinical trials investigating the efficacy of BP

The research aim in this paper is to outline, detail and come to a deeper understanding as to why AIDS/HIV corporate social responsibility CSR initiatives have not been truly successful in the Central District of Botswana. I will focus on the following aspects in the analysis; history, stigma, gender and traditional values, and the corporate refocus on the blood diamond movement. Botswana is a m

Authors: Karin Lindsjö and Johanna Rydiander Title: Leadership in social work: A study of requested variables regarded middle level leaders during recruitment [translated title] Supervisor: Kristina Göransson Assessor: Staffan Blomberg Although working as a leader at middle level within social work is an interesting research area with its complex nature, there is not much science regarding this f

It is well-known that clay can form lamellar structures i.e. tactoids, and recently it has been shown that the tactoid formation is dependent on the platelet diameter. To the authors knowledge, no tactoid formation has been observed for montmorillonite platelets with a diameter less than 60nm. In this study, small angle X-ray scattering in combination with coarse-grained modeling and molecular dyn

Satsningen på vindkraft som en del av Sveriges gröna omställning har lett till ökade etableringar i Sápmi, med konsekvenser för den samiska kulturen. Samiska företrädare har kopplat denna exploatering till det historiska fråntagandet av samisk mark och benämnt detta som grön kolonialism. Samtidigt är samerna särskilt drabbade av de klimatförändringar vindkraften är tänkt att motverka. Denna uppsaThe expansion of wind power as part of Sweden’s green transition has led to increased development in Sápmi, with consequences for Sámi culture. Sámi representatives have linked this exploitation to the historical dispossession of Sámi land and referred to it as green colonialism. At the same time, the Sámi people are particularly affected by the climate change that wind power is intended to mitiga

This interdisciplinary thesis examines the nexus of memory, war, and digitality inthe context of the Russian invasion of Ukraine. Since 2014, the unfolding Russianwar against Ukraine has epitomised how rapid technological developments haveprofoundly altered the ways in which warfare is depicted, perceived, and waged intoday’s world. These transformations have enabled new forms of engagement withwa

While a naive algorithm for multiplying two 2 × 2 matrices requires eight multiplications and four additions, Strassen showed how to compute the same matrix product using seven multiplications and 18 additions. Winograd reduced the number of additions to 15, which was assumed to be optimal. However, by introducing a change of basis, Karstadt and Schwartz showed how to lower the number of additions

Introduction: Wildfires pose escalating risks to communities at the wildland--urban interface, often necessitating extensive evacuations. This thesis explores how driving behaviour during wildfire evacuations differs from routine conditions and how these differences can be modelled to improve traffic simulations, thereby supporting more informed planning and response decisions by authorities.Objec

Background: Based on the current understanding of the role of neuropeptide signalling in migraine, we explored the therapeutic potential of a specific cannabinoid agonist. The aim of the present study was to examine the effect of the synthetic endocannabinoid (eCB) analogue, arachidonyl-2′-chloroethylamide (ACEA), on calcitonin gene-related peptide (CGRP) release in the dura and trigeminal ganglio

Background: Despite known benefits of physical activity in reducing breast cancer risk, its impact on mammographic characteristics remain unclear and understudied. This study aimed to investigate associations between pre-diagnostic physical activity and mammographic features at breast cancer diagnosis, specifically mammographic breast density (MBD) and mammographic tumor appearance (MA), as well a

Background: High-dose haemodiafiltration has been shown, in a randomised clinical trial, to result in a 23% lower risk of mortality for patients with kidney failure when compared with conventional high-flux haemodialysis. Nevertheless, whether treatment effects differ across subgroups, whether a dose–response relationship with convection volume exists, and the effects on cause-specific mortality r
