Nerve regeneration, measured as axonal outgrowth, Schwann cell migration, macrophage invasion, and neovascularisation, was compared after repair of a 15 mm gap in rats' sciatic nerves using autologous muscle grafts made acellular either by freezing and thawing or by chemical extraction. Both extracted and freeze-thawed acellular muscle grafts could be used to bridge the defect. However, axons and
In this paper, the formaldehyde emissions from three different types of homogenous charge compression ignition (HCCI) engines are quantified for a range of fuels by means of Fourier Transform Infra Red (FTIR) spectroscopic analysis. The engines types are differentiated in the way the charge is prepared. The characterized engines are; the conventional port fuel injected one, a type that traps resid
New basis sets of the atomic natural orbital (ANO) type have been developed for the first, second, and third row transition metal atoms. The ANOs have been obtained from the average density matrix of the ground and lowest excited states of the atom, the positive and negative ions, and the atom in an electric field. Scalar relativistic effects are included through the use of a Douglas-Kroll-Hess Ha
Group G streptococci (GGS) may be of four different species and may infect humans and also animals. S. dysgalactiae equisimilis most commonly cause human GGS infections. These bacteria are part of the normal flora, but can cause pharyngitis, erysipelas and impetigo. In the immunocompromised host severe conditions, such as sepsis and necrotising fasciitis, may develop. In this thesis the interactio
Objective: The hemodynamic effects of vacuum-assisted closure therapy in cardiac surgery are debated. The aim of the present study was to quantify cardiac output and left ventricular chamber volumes after vacuum-assisted closure using magnetic resonance imaging, which is known to be the most accurate method for quantifying these measures. Methods: Six pigs had median sternotomy followed by vacuum-
Routine postmortem radiography was done in 234 consecutive perinatal autopsies. Using ossification centre appearance and length of femoral shafts as variable it was a very useful and dependable method for estimating gestational age and intrauterine growth. In this way important conclusions can be drawn as to the reason for intrauterine growth deviations. Also many, sometimes diagnostic, abnormalit
Syftet med studien är att undersöka vilken roll takt och rytm spelar i en idrottslärares undervisning. För att förtydliga uppsatsens syfte och beskriva idrottslärarnas uppfattning behandlas följande forskningsfrågor: Hur ser idrottslärare på takt och rytm i sin undervisning? Vad uppfattar idrottslärare att det är de ska undervisa i när det gäller takt och rytm enligt kursplanen? Hur ser idrottslärMeasure and rhythm: What part do concepts of measure and rhythm play in a physical education teachers way of teaching? The purpose of this study is to determine what part the measure and rhythm plays in a physical education teacher's way of teaching. To clarify the purpose of this study and describe physical education teachers' perception, the following research questions are processed: Ho
Both Northern Ireland (NI) and the Republic of Ireland (ROI) have set ambitious targets for increasing the amount of renewable heat being generated. By 2020, NI is aiming for a 10% target, in the Republic a 12% target has been stipulated (DARD, 2010) (SEAI, 2007). In both countries the majority of the private forest estate has been created through establishment grants that began in the 1980s, the
Till varje stats suveränitet hör utformningen av dess beskattning. Eftersom flertalet stater använder sig av olika principer vid bestämmandet av beskatt-ningsanspråken leder detta ofta till dubbelbeskattning för företag och indivi-der. Motverkandet av den ofördelaktiga beskattningen sker genom en till-lämpning av skatteavtal då deras syfte primärt är att undanröja eller lindra följderna av internaDesigning of the taxation system belongs to the sovereignty of each state. Since most states use different principles in determining the taxable claims, this often leads to double taxation of companies and individuals. The avoid-ance of the unfavorable taxation is made through the practice of tax treaties, as their primary purpose is to eliminate or mitigate the consequences of in-ternational judi
This study identifies a negative impact of mining on access to the public water system in Peru using district data from 2011 and a similar methodology as Loayza, Mier y Teran and Rigolini (2013). One potential explanation for this result can be found by assessing the effects of mining on the investment prioritization of local governments; responsible for providing basic services in Peru. A quantit
Syftet med denna studie är att undersöka vilken effekt ett medlemskap i den Europeiska unionen har haft på Sveriges politiska partiers kommunikation. För att genomföra undersökningen har vi använt de politiska partierna i Norge som referenspunkt. Denna studie använder sig av ”theory of Europeanization” och ”Greens theory of Salience Issues” som teoretisk grund för att försöka förklara den förändri
There has been a decrease in sea ice extent and volume in the polar regions during the past decades; this study focuses on the Northern Hemisphere. The variability of the sea ice extent along the east coast of Greenland is examined and the area is divided into three regional zones to be able to study variations in the correlation strength along the coast. The ice extent along the east coast is ach
This study investigates whether Swedish students, at two different levels of study, are able to distinguish between ‘it’ and ‘there’ when using the two as dummy subjects. This particular feature was chosen since previous research (e.g. Estling- Vannestål, 2007; Köhlmyr, 2003; Davidsen-Nilsen & Harder, 2001 ) has shown that Swedish students tend to overuse ‘it’ in such constructions: something
På bangården i Nässjö har det mellan 1918 och 2005 legat en impregneringsanläggning för järnvägsslipers. Som impregneringsmedel användes främst kreosotolja vilket innehåller polycykliska aromatiska kolväten (PAH) som kan vara skadliga för människa och natur. Marken på bangården är nu kraftigt förorenad och ska därför saneras. Tyréns AB har på uppdrag av Trafikverket tagit fram ett förfrågningsundA facility for preservation of wooden rail road sleepers has been operating at the railway yard in Nässjö between 1918 and 2005. The main preservative used at the site was creosote which contains polycyclic aromatic hydrocarbons (PAH) that can be harmful to humans and the environment. The soil at the railway yard is due to these activities heavily polluted and the Swedish Transport Administration
Sedan 2015 har Sverige en uttalat feministisk utrikespolitik, med målet att ett genusperspektiv ska genomsyra all politisk verksamhet. Parallellt med denna nya politiska inriktning fortsätter Sverige att exportera krigsmateriel till icke-demokratiska och konfliktdrabbade stater, något som har gett upphov till kritik. Genom att granska den statliga myndighet som ansvarar för beslut om krigsmateriel
Syftet med denna kvalitativa studie är att undersöka hur patienter med traumarelaterad diagnos eller depression beskriver upplevelser och erfarenheter av självupplevda trauman för att få en bättre uppfattning om trauma som fenomen. Generellt beskrivs trauma som ett tydligt fenomen, som avskiljs från naturliga händelser i livet och som innefattar både subjektiva reaktioner och långvariga konsekvensThe aim of this qualitative study is to investigate aspects of trauma from a patients point of view, who have post traumatic stress disorder or depression, in order to get a better understanding about trauma as a phenomena. The overall conclusion is that trauma is described as a specific phenomena, that is an event that is not part of normal life and which includes aspects of the persons reaction
Problem: The open innovation research landscape is comprised of complex and fuzzy concepts, theories, and frameworks, as researchers have developed and relied on varying theoretical concepts that encompass diverse dimensions. The bulk of such research within this space is seen to be constituted by large companies with a lack of consideration for SMEs. Therefore, a framework and guideline that high
