The genus Caldicellulosiruptor and especially Caldicellulosiruptor saccharolyticus are gaining attention because of their potential as biohydrogen producers from agricultural and forestry waste on an industrial scale. Genetic and in turn metabolic engineering can be used to aid in the characterization of C. saccharolyticus. Additionally, it can be used in strain improvement to overcome limiting fa
Water chemistry alterations such as acidification and eutrophication represent major threats to the running waters of the world, and Swedish waters are among the most vulnerable. In this study the small forested catchment Storskogen, part of the SWETHRO monitoring network, was analysed to examine the links between deposition, catchment hydrological properties and surface water chemistry. Storskoge
MicroRNAs are small single stranded RNA molecules containing approximately 22 nucleotides and these play an important regulatory role in gene expression. MicroRNAs are found to be involved in several diseases and knowledge about their sequences can be an important tool in the foundation of novel treatment methods against diseases. Today, these small RNA molecules are mainly analyzed with qPCR and
The undrained shear strength is a key parameter in the design process of geotechnical structures. One of the most frequently used methods to investigate this parameter is the cone penetration test (CPT). The CPT does not measure the undrained shear strength directly, but instead the resistance that a conic probe encounters as it is pushed into the ground. A calibration factor, the cone factor (Nkt
The steel industry is a large emitter of carbon dioxide and uses a lot of energy. Because of an increased awareness of the detrimental effects of climate change, research in alternative ways to operate steel plants have been made. It is now possible to build plants with far less emissions by using electrolysis and hydrogen reduction. Electrolysis is a technology with a long historical background t
As a result of 20th-century car-centric planning, many urban districts had emerged designed to serve only one function. Different residential suburbs and trade areas were dispersed scattered within and outside the cities. This has led to more dependence on private cars to meet people’s daily needs. Urban Ergonomics will discuss one type of these areas, the external shopping centers, or the big-bo
In the Formox-process, methanol is converted to formaldehyde via partial oxidation on a heterogeneous iron-molybdate catalyst. To an extent, the formed formaldehyde (FA) is over-oxidized into carbon monoxide (CO) which cannot be recycled into FA. As CO affects the environment negatively and decreases the process economy, internal attempts have previously been made to decrease the CO formation of t
This thesis is an ethnographic exploration of Swedish sauna practices as experienced by international students at Lund University. The research objective is to navigate experiences of belonging and community formation that occur in the sauna, but also highlights how experiences of outsiderness and exclusion come to the fore in this highly sensorial environment. The sauna is analysed as a microcosm
This thesis presents a case study of an indoor Green Wall (GW) installed in an office building in Malmö, Sweden. The study analyzed the effect of the GW on air humidity during low temperature and dry moisture outdoor conditions. The objective was to determine the green wall's indoor humidity contribution while enabling an adequate comparison before and after the GW installation, which requires
”Most of Sweden’s surface is covered by forest, 68 percent is woodland; the built-up and landscaped land does not make up more than 3 percent of Sweden’s total land area. About 50% of the forest land is made of pine (Pinus sylvestris), making it the most common tree species in the country’s forests.” In the 70s, a design movement was established in Swedish homes “ Svensk fur”. It was cheap, hones
Mouse apolipoprotein M (m-apoM) displays a 79% sequence identity to human apolipoprotein M (h-apoM). Both proteins are apolipoproteins associated with high-density lipoproteins, with similar anticipated biological functions. The structure of h-apoM has recently been determined by X-ray crystallography, which revealed that h-apoM displays, as expected, a lipocalin-like fold characterized by an eigh
Endothelial cells are among the main physiological targets of the pro-inflammatory cytokine tumor necrosis factor-alpha (TNF-alpha). In endothelial cells TNF-alpha elicits a broad spectrum of biological effects including differentiation, proliferation and apoptosis. alpha 1-antitrypsin (AAT), an endogenous inhibitor of serine proteases plays a vital role in protecting host tissue from proteolytic
The development of models that provide accurate spatio-temporal predictions of ambient air pollution at small spatial scales is of great importance for the assessment of potential health effects of air pollution. Here we present a spatio-temporal framework that predicts ambient air pollution by combining data from several different monitoring networks and deterministic air pollution model(s) with
Sera from 25 metastatic breast cancer patients and 25 healthy controls were subjected to affinity chromatography using immobilized galectin-1. Serum from the healthy subjects contained on average 1.2 mg per ml (range 0.7-2.2) galectin-1 binding glycoproteins, whereas serum from the breast cancer patients contained on average 2.2 mg/ml (range 0.8-3.9), with a higher average for large primary tumour
Background: Renalase (gene name RNLS), a recently discovered enzyme with monoamine oxidase activity, is implicated in the degradation of catecholamines. Recent studies delineate a possible role of this enzyme in blood pressure (BP) maintenance and cardiac protection and two single nucleotide polymorphisms, RNLS rs2576178 A > G and rs2296545 C > G have been associated with hypertension. The latter
The papilloma- and polyomaviruses are small DNA viruses that infect humans. Some members of these virus families can cause cancer in experimental animals and some are also established as carcinogenic to humans. Detection of specific antibodies to these viruses allows tracking past and present infections to elucidate natural history and association of infection with subsequent disease. As there are
Currently, the majority of spent batteries are not recycled but become part of the household waste in many countries, especially in China which is the largest producer and consumer of batteries. This is due to many reasons, including the lack of governmental policies to encourage and facilitate battery return and recycling. In that context this research was designed to investigate the attitudes an
With the climate change and urbanization process, the frequency of the urban flooding’s occurrence has increased in the recent years. It brings great economic losses to the cities, especially to the basements of individual properties. Low Impact Development (LID), which currently advocated by more city planners for managing stormwater, is considered as a more sustainable way to mitigate urban floo
