In the search for high efficiency combustion systems pulsating combustion has been identified as one of the technologies that potentially can meet the objectives of clean combustion and good fuel economy.Pulsating combustion offers low emissions of pollutants, high heat transfer and efficient combustion. Although it is an old technology, the interest in pulsating combustion has been renewed in rec
Lignocellulose is widely recognized as a Sustainable substrate for biofuels production, and the enzymatic hydrolysis is regarded as a critical step for the development of ail effective process for the conversion of cellulose into ethanol. One key factor affecting the overall conversion rate is the adsorption capacity of the cellulase enzymes to the surface of the insoluble substrate. Pretreatment
Weak alignment of requirements engineering (RE) with verification and validation (VV) may lead to problems in delivering the required products in time with the right quality. For example, weak communication of requirements changes to testers may result in lack of verification of new requirements and incorrect verification of old invalid requirements, leading to software quality problems, wasted ef
Denna uppsats utreder vilken roll skiljeförfaranden spelar och kan spela i det privata genomförandet av EU:s konkurrensregler. Det beskrivs och diskuteras hur konkurrensreglernas offentligrättsliga drag påverkar skiljeförfarandet, hur korrekt och enhetlig tillämpning av konkurrensreglerna i skiljeförfaranden kan säkerställas och hur konkurrensmyndigheter kan använda skiljeförfaranden som ett verktThis thesis investigates which role arbitration has and could have in the private enforcement of EU competition law. It is described and discussed how the public law features of competition law affect the arbitration process, how a correct and uniform application of the competition rules can be ensured in arbitration proceedings, and how competition authorities can use arbitration as a tool in the
Zirkon från magmatiska bergarter extraherades från fem granitoider i Birimianterrängen i Ghana., och detritala zirkoner provtogs från sex platser i centrala Västgrönland. Av dessa härrör en population från palaeoproterozoikum i Prøvens magmatiska komplex. De återstående fem detritala populationerna härrör från Arke-iska källor i Västgrönland. Zirkon-populationerna analyserades med LA-ICP-MS-teknikZircon were extracted from five granitoids in the Birimian terrane in Ghana, and detrital zircon were sampled from six locations in Central West Greenland. Of these, one population is derived from the Palaeoprotero-zoic Prøven Igneous Complex. The remaining five populations are derived from the Archean basement in Central West Greenland. Zircon populations were analyzed with the LA-ICP-MS techniqu
I och med de utmaningar som mänskligheten idag står inför, med stora klimatförändringar, ökad urbanisering och en global ekonomi kan städer komma att spela en central roll i hållbarhetsarbetet. Det är av vikt att beslutsfattare i städer kan förstå, hantera och styra på ett sätt att städerna utvecklas till hållbara samhällen med hållbara processer. Frågan är hur väl beslutsfattarnas sätt att hanterWith the challenges facing humanity today, with rapid climate changes, an increased urbanization and a global economy, cities can play a central role in sustainable development. It is important that decision-makers in the cities can understand, manage and govern in a way that cities develop into sustainable communities with sustainable processes. The question is how well the decision-makers' w

Instead of investing 145 billion SEK in building a new high speed rail network, much greater value in terms of transport capacity is likely to be found in constructing a new system of tube transport with a travel speed of 600 km/h. The suggested technology does not exist yet. However, research and development is advancing and accepting that a new technology is emerging might be the greatest hurdle
Shedding of epithelium, increased venular permeability, and traffic of activated eosinophils and neutrophils may characterize asthmatic airways. This in vivo study involving briefly anesthetized guinea pigs examines whether epithelial denudation itself affects airway venules and granulocytes. Using an oral probe, a de-epithelialized tracheal zone (0.8 x 30 mm) was produced without bleeding or dama
Betong är ett av byggsektorns mest använda material, men cementproduktionen står för stora koldioxidutsläpp. Ett sätt att minska klimatpåverkan är att reducera andelen cementklinker genom att använda alternativa bindemedel. Vulkanisk puzzolan från Island, VPI är ett tillsatsmaterial från Heidelberg Materials Cement Sweden som kan användas tillsammans med cement som bindemedel i betong. TillsatsmatConcrete is one of the most widely used materials in the construction sector, but cement production is associated with a significant climate impact. One way to reduce this impact is to decrease the proportion of cement clinker by using alternative binders. Volcanic pozzolan from Iceland, VPI, is a supplementary material supplied by Heidelberg Materials Cement Sweden that can be used together with
Laser-induced photofragmentation fluorescence has been investigated for the imaging of alkali compounds in premixed laminar methane–air flames. An ArF excimer laser, providing pulses of wavelength 193 nm, was used to photodissociate KCl, KOH, and NaCl molecules in the post-flame region and fluorescence from the excited atomic alkali fragment was detected. Fluorescence emission spectra showed disti
Background: Neuropeptides, such as substance P (SP), have long been seen as mediators of widespread continuous airway inflammation, a process known as neurogenic inflammation. However, this has been difficult to demonstrate clinically, suggesting an alternative role for these signaling molecules. Objectives: We sought to examine the role of SP in nasal infection by assessing the release of SP in r
In this paper we call into question the relationship between development, inequality and territory in the current context of globalization and within the framework of public policies designed, supposedly, to benefit those social actors with fewer resources. In order to do this, we focus on a case study in the northeast of the province of Misiones, Argentina. Here tobacco production, forestry and a
In plants the chloroplast thylakoid membrane is the site of light-dependent photosynthetic reactions coupled to ATP synthesis. The ability of the plant cell to build and alter this membrane system is essential for efficient photosynthesis. A nucleotide translocator homologous to the bovine mitochondrial ADP/ATP carrier (AAC) was previously found in spinach thylakoids. Here we have identified and c
This thesis contributes to research on experimental and behavioral economics as well as auction theory. It consists of five papers.The first paper, Differences Attract: An Experimental Study of Focusing in Economic Choice, studies whether individuals' decisions are affected by focus effects. The focus effect suggests that individuals focus more on an attribute that has a larger difference among th
Metamorphic provinces such as the ∼1 Ga Grenvillian, ∼400 Ma Caledonide and Triassic Qinling Provinces often contain rocks with high-pressure assemblages such as eclogites, which formed at mantle depths in subduction zones. These are evidence of the accretion of terranes by subduction of oceans and collision to form large tectonostratigraphic provinces. The Mesoproterozoic Namaqua-Natal Province
Parkinson’s disease (PD) patients frequently develop cognitive impairment. There is a need for brief clinical assessments identifying PD patients at high risk of progressing to dementia. In this study, we look into predicting dementia in PD and underlying structural and functional correlates to cognitive decline in PD. We included 175 patients with PD, 30 with PD dementia, 51 neurologically health
There is a growing interest in organized self-help housing (OSHH) from both authoriti es and Non Governmental Organizati ons (NGOs) working in the housing sector due to the magnitude of housing problems in developing countries and the challenge of achieving sustainable humansett lements. This paper focuses on the experiences of two NGOs, FUPROVI in Costa Rica and SADEL in Sweden, in facilitati ng
