Popular Abstract in English News about global warming, discussions about alternative fuels such as natural-gas and biogas, and commercials about gas engines sound familiar to the most people living in modern societies. Why global warming is important? What is the role of natural-gas engines in this subject? Are natural-gas engines efficient? Do they perform as well as diesel engines? If not, why? Most heavy-duty engines are diesel operated. Severe emission regulations, high fuel prices, high technology costs (e.g. catalysts, fuel injection systems) and unsustainably in supplying fuel are enough reasons to convenience engine developers to explore alternative technologies or fuels. Using natural gas/biogas can be a very good alternative due to the attractive fuel properties regarding emissio

This study explores the use of manganese ore, iron-carbon particles (Fe-C), and gravel as anode fillers in electroactive constructed wetlands (ECWs) to treat wastewater containing pharmaceuticals and personal care products (PPCPs) including ciprofloxacin (CIP), ofloxacin (OFL), and naproxen (NPX), while also assessing bioelectricity production. Although the presence of PPCPs reduced pollutant remo

Streptococcus pyogenes is one of the most common bacteria infecting humans. One of the factors contributing to the disease-causing properties is the secreted streptococcal cysteine proteinase, SpeB, which degrades several host proteins in connective tissue and circulation. SpeB activity depends on the transformation from an inactive precursor, zymogen, into a mature proteinase. We show that

Catalytic processes have tremendous importance in our everyday life. Most chemicals, pharmaceuticals, plastics etc. are, in fact, produced with the help of catalysts. What is probably even more important is that the toxic wastes produced in great amounts by modern factories and plants are recycled or transformed into less poisonous substances by means of catalytic units. One example from our everyThe present work is devoted to atomic scale structural studies of the surfaces of model heterogeneous catalysts relevant to oxidation reactions. A novel approach using high-energy surface X-ray diffraction combined with mass-spectrometry measurements is employed to perform in situ structural characterization of Pd(100) and Pd(553) single crystal surfaces acting as catalysts in the process of CO ox

Problem: The Chinese WEEE recycling market is today operated mostly by the informal sector. As this sector eludes the insufficiently enforced environmental laws the e-waste is recycled by means not only harmful to the environment and people working with the recycling process, but it also utilizes methods that do not recover valuable materials in a sound and efficient way. Many companies stand read

Populärvetenskaplig sammanfattning:En studie publicerad av NASA:s Goddard Institute for Space Studies år 2019 visade att de genomsnittliga globala temperaturerna under de senaste fyra åren (2015-2018) var de högsta som någonsin registrerats i människans historia. Den nyheten passar väl in i de alarmerande prognoserna om global uppvärmning, och kräver snabba och radikala handlingar. Att studera “teInnovative design and materials are needed to satisfy the demand for efficient and scalable devices for electronic and opto-electronic applications, such as transistors, LEDs, and solar cells. Nanostructured III-V semiconductors are an appealing solution, combining the excellent functional properties of III-V materials with the flexibility typical of nanostructures, such as the nanowires (NWs) stu

Prekonceptionell hälsa och rådgivning Kvinnor och mäns levnadsvanor inför graviditet påverkar fostret och det blivande barnets hälsa. Under våren 2019 ges en utbildning i Prekonceptionell hälsa och rådgivning vid Lunds universitet. Utbildningen är den första kursen i Sverige inom prekonceptionell hälsa, vilket gör den unik i sitt slag. Den riktar sig till barnmorskor generellt, och i synnerhet til

It is obviously expected that sustainable development is the primary target to raise prosperity and life standards of nations. It is necessary to ensure social, political, and economic stability. But what about the stimulus factors that motivate sustainable development? Can income inequality be one of them? Some literature has examined the role of income distribution on economic growth, but to te

The purpose of this thesis is to gain an understanding of the credibility gap between consumers and marketing strategies that aims at gaining moral legitimacy by taking a stand, since it is becoming increasingly important for companies to gain moral legitimacy. By triangulating theories within consumer culture theory, corporate social responsibility and organizational legitimacy and conducting a q

Perlecan is a heparansulfate proteoglycan found in basement membranes, cartilage, and several mesenchymal tissues that form during development, tumour growth, and tissue repair. Loss-of-function mutations in the perlecan gene in mice are associated with embryonic lethality caused primarily by cardiac abnormalities probably due to hemopericards. The aim of the present study was to investigate the m

Neurocan is a component of the extracellular matrix in brain. Due to its inhibition of neuronal adhesion and outgrowth in vitro and its expression pattern in vivo it was suggested to play an important role in axon guidance and neurite growth. To study the role of neurocan in brain development we generated neurocan-deficient mice by targeted disruption of the neurocan gene. These mice are viable an

The meiotic functions of Emi2, an inhibitor of the APC/C complex, have been best characterized in oocytes where it mediates metaphase II arrest as a component of the cytostatic factor. We generated knockout mice to determine the in vivo functions of Emi2—in particular, its functions in the testis, where Emi2 is expressed at high levels. Male and female Emi2 knockout mice are viable but sterile, in

Flight is an expensive form of locomotion, but also offers the ability to travel great distances at relatively low cost. Birds have developed various adaptations for optimizing flight performance. The main aim of this thesis is to identify how morphological variables in birds affect aerodynamic drag and flight performance. To this end I studied the aerodynamic performance of a jackdaw (Corvus mone
