The product H2 is a new heat exchanger produced, manufactured and sold by Heatex. It has an excellent surface efficiency, in large parts because of its slim features. The slim features does however have a drawback. It isn’t as mechanically stable and robust as its earlier cousins. The product tends to deform plastically in lifting conditions, especially the heavier versions needs extra support or,
This study reviews the influence of the Environment Board in municipal spatial planning in the city of Malmö and aims to highlight improvements in the consultation process. The municipalities are responsible for planning how land and water resources are to be used and thus central in attaining a sustainable land use and urban planning. Development plans are created by The City Planning Office and
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
As the demand for eco-friendly alternatives to traditional plastics grows, Polyethylene Furanoate (PEF) emerges as a promising solution. Derived from renewable biomass sources, PEF embodies sustainability principles by reducing reliance on finite resources and minimizing environmental impact. PEF is synthesized from 2,5-furandicarboxylic acid (FDCA), a key monomer which upon polymerization has the
I Sverige finns många förorenade områden med klorerade lösningsmedel och Färgaren 3 i Kris-tianstad är ett av dem. Där har tidigare legat en kemtvätt som använt sig av PCE (Tetrakloreten), där spill och läck-age har förorenat stora delar av fastigheten. PCE och dess metaboliter har en tendens att förorena stora volymer, vilket gör dessa ämnen svåra att sanera. Detta mastersarbete inriktar sig på a
A large share of the existing building stock in Sweden originates from the so-called Million Building Programme, a large-scale construction wave between 1965 and 1974 to tackle the housing shortage at this time. Those buildings have very high energy demand and require renovation due to age and often neglected maintenance. The Swedish government’s long-term climate and energy goals are tied to an e
The coastal city of Kalmar is known as an attractive summer destination, both locally and internationally. The coast has long been included as one of the municipality’s priority goals. In its city development vision, the municipality strives to utilize the coast and take it into consideration in urban planning. On the other hand, Kalmar has a historic character, which is visible through its urban
Global warming and climate change is getting a serious issue and a great environmental threat that affects many aspects of life and our ways of living on this planet. The negative effects of climate change are endangering our communities, health and economy. Global warming can be considered as a main reason for sea rising levels, extreme heat which is responsible for many forests’ fires, severe dr
