Cementproduktion står idag för en ansenlig andel av världens koldioxidutsläpp, vilket driver utvecklingen av bindemedel med lägre koldioxidutsläpp. För utsläppen i ett längre perspektiv är dock de nya bindemedlens beständighet absolut avgörande. De flesta nedbrytningsmekanismer är direkt relaterade till både fukt- och jontransport. Dessa processer har undersökts i många studier, men huvudsakligen Cement production is responsible for a significant portion of manmade CO2 emissions. This motivates the development of cementitious binders with a lower carbon footprint. Considering the emissions in a longer perspective, the durability of concrete structures is absolutely essential. Most degradation of concrete structures is closely related to both moisture transport and ion transport. Many studi
Background: Albumin may be beneficial in patients with septic shock but availability is limited and cost is high. The objective of the present study was to investigate if the use of dextran-70 in addition to albumin and crystalloids influences organ failure or mortality in patients with severe sepsis or septic shock. Methods: Patients with severe sepsis or septic shock (n = 778) admitted to a univ
Background: The aim was to evaluate what can be learned from rat models when treating patients suffering from a sciatic nerve injury.Methods: Two patients with traumatic sciatic nerve injury are presented with examination of motor and sensory function with a five-year follow-up. Reconstruction of the nerve injury was performed on the second and third day, respectively, after injury using sural ner
Popular Abstract in English Lions (Panthera leo) have become known to be synonymous with wild Africa since its extinction from most parts of its former range (Europe, Asia and Southern America). Few people realize that anthropogenic activities have caused habitat loss, fragmentation and reduction in size to the lions, forcing them to the brink of extinction. Whenever out in nature, most tourists tHigh growth rate in human populations, agricultural developments and industrialization have impinged negatively on the natural habitats of most large carnivores, causing fragmentation, isolation and consequently reduction in population size. Lions (Panthera leo) that once roamed most parts of Southern Europe, Asia, the Middle East, North America, northern part of South America and most parts of Af
BACKGROUND: Discharge summary with medication report effectively counteracts drug-related problems among elderly patients due to insufficient information transfer in care transitions. However, this requires optimal transfer and use of the discharge summaries. This study aimed to examine information transfer with discharge summaries from hospital to primary care.METHODS: A descriptive study with da
BACKGROUND: The optimal advanced heart failure (HF) therapy strategy for patients aged 60 or older with end-stage HF refractory to optimal medical therapy remains uncertain. This study compares outcomes of three advanced HF therapy strategies in this patient population. METHODS: A single-center retrospective study was conducted in 95 patients aged 60-73 years who had undergone isolated heart trans
Popular Abstract in English The cell is the basic unit in all organisms. The molecular machinery in cells converts the energy in sunlight or food into a form of energy that the cell can use for physiological processes in the organism. In humans, this molecular machinery is located in the mitochondria; therefore they are often called the power plants of the cell. The molecular machines are actuallyNADH:quinone oxidoreductase, or complex I, is a large membrane bound enzyme in the respiratory chain of living organisms, that has evolved from the combination of smaller functional building blocks. The enzyme has a conserved core structure, comprising 14 protein subunits: Seven subunits protrude from the membrane and contain a flavin and eight iron-sulfur clusters. The remaining seven subunits in
Modern office buildings have high energy savings potential and potential for indoor climate improvements. During the nineties many office buildings with glass facades were built, in several cases with double skin glass facades. The advantages of buildings with double skin facades (compared with single skin glazed ones) are considered to be the reduced heating and cooling demand, the increased soun
Popular Abstract in Swedish Inom hälso- och sjukvården betonas att vården ska ges utifrån ett patientorienterat sätt. Om sjuksköterskor skall kunna ge patienten god omvårdnad, måste de själva ha en god arbetssituation. Det blir allt vanligare att sjuksköterskor i arbetet utsätts för en mängd negativa psykiska påfrestningar, såsom hot och våld, som kan leda till stress. Stress kan också relateras tThe purpose of group supervision in nursing care is to understand nurses’ experiences from real care settings and to structure these in a professional and personal context. An interventional and longitudinal method of research was chosen in this study of group supervision in nursing care. The overall aim of the present study was to examine and investigate how psychiatric nurses’ professional compe
Tidigare forskning om motivation vid lärande har tenderat att fokusera på attributioner (de tolkningar elever och andra gör av orsaker till framgångar och misslyckanden) självuppfattning, målorientering och elevers autonomi. Denna avhandling syftar dels till att beskriva bakgrunden och skolgången för de elever som går på gymnasiets estetiska programs musikgren, dels till att mäta den motivation deIn previous studies research on motivation in education has tended to be focused on attribution (perceived causes of success and failure), self perception, goal orientation and autonomy. This thesis aims to describe the background and schooling of music students and to measure their motivation for music education. Motivation is viewed as a cognitive process, which influences learning through achie
RATIONALE AND OBJECTIVES: We wanted to improve determination of the glomerular filtration rate (GFR) with plasma clearance techniques because the alternative-renal clearance techniques-may involve inaccurate urine sampling or risk of urinary tract infection when bladder catheterization becomes necessary. Therefore, we compared the renal and plasma clearances of iohexol and chromium-51-ethylenediam
Currently, we are experiencing biodiversity loss on different spatial scales. One of the best studied taxonomic groups in decline is the butterflies. Here, we review evidence for such declines using five systematic studies from southern Sweden that compare old butterfly surveys with the current situation. Additionally, we provide data on butterfly and burnet moth extinctions in the region’s counti
Contamination of soil and water by heavy metal ions (HMs) is a problem all over the world.The use of biological methods alone or in combination with other techniques for treatment of such polluted sites constitutes a major challenge. The present thesis summarizes work based on four basic technologies: 1) use of Sulphate Reducing Bacteria (SRBs) for production of hydrogen sulphide which is used to
This thesis is focused on the detail process of formation of mesoporous silica materials.Mesoporous silica materials are one type of porous materials with a pore size between 2 and 5 nm (1 nm=0.000 000 001 m). The pore walls consist of silicon dioxide – silica (sand also consists of silica). The mesoporous silica materials are formed by amphiphilic molecules, a kind of molecule with one part that We investigate the formation mechanism responsible for two specific systems of mesoporous silicas formed with the so-called co-structure directing agent (CSDA) route. The synthesis relies on the interactions between silica source (tetraethylorthosilicate, TEOS), surfactants and CSDA. The structures of the mesoporous silica materials were investigated mainly by small angle X-ray diffraction (SAXD),
Background. In the past years, there has been a major shift towards the consumption of healthier, more sustainable, and more convenient food products. These trends have triggered a response from the food industry, instigating the reformulation of several products. The challenge is removing or replacing certain ingredients, without sacrificing certain elements such as taste, texture, or shelf-life.
Popular Abstract in Swedish Bakgrund Den kroniska ögonsjukdomen grön starr (glaukom) skadar ögats synnerv och påverkar den perifera synen (synfältet) hos de som drabbas. I västvärlden är grön starr den näst vanligaste orsaken till blindhet enligt Världshälsoorganisationen WHO. I Sverige räknar man med att cirka 70 000 personer över 70 år har grön starr, men att endast hälften av dessa är kända föThis thesis addresses several aspects of glaucoma diagnostics from both a clinical and a screening perspective. New instruments for diagnosing glaucoma have been developed over the past years, but little information is available regarding their performance as screening methods and their usefulness in ordinary clinical practice. Purpose of the research underlying this thesis The objectives of th
Popular Abstract in Swedish Diabetes mellitus är en samling sjukdomar som karaktäriseras av förhöjt blodsocker. Traditionellt har man delat upp sjukdomen i två former; typ 1 och typ 2 diabetes. Vid typ 1 diabetes förstörs de insulinproducerande β-cellerna i bukspottskörteln av kroppens immunförsvar och sjukdomen debuterar ofta tidigt i livet. Typ 2 diabetes, tidigare ofta benämnd ”åldersdiabetes” Inadequate insulin secretion is a central component in the development of Diabetes Mellitus, resulting from reduced pancreatic β-cell mass, as well as diminished β-cell function. Islet produced 5-hydroxy tryptamine (5-HT) is suggested to regulate insulin secretion and β-cell mass in rodents during pregnancy and in metabolically challenged states. However, the role of 5-HT in control of insulin rel
Background: Overdiagnosis and subsequent overtreatment are important side effects of screening for, and early detection of, prostate cancer (PCa). Active surveillance (AS) is of growing interest as an alternative to radical treatment of low-risk PCa. Objective: To update our experience in the largest worldwide prospective AS cohort. Design, setting, and participants: Eligible patients had clinical
