Due to the small characteristic molecular size of hydrogen, small leaks are more common in hydrogen systems compared to similar systems with hydrocarbons. This, together with the high reactivity, makes an efficient ventilation system very important in hydrogen applications. There are several models available for ventilation sizing that are based on either a well-mixed assumption or a fully stratif
Cities are the pinnacle of human change to the environment, creating unique types of ecosystems which present many challenges to local organisms: habitat fragmentation, introduced species, and various pollutants. Being crucibles of anthropogenic effects, urban ecosystems offer opportunities to understand how humans impact nature. Moreover, since a majority of the world’s population resides in citiCities are the pinnacle of human change to the environment, creating unique types of ecosystems which present many challenges to local organisms: habitat fragmentation, introduced species, and various pollutants.

Popular Abstract in English Polyhydroxybutyrate (PHB) is a homopolymer belonging to the family of biopolyesters, polyhydroxyalkanoates (PHA) produced by different bacteria and archaea as intracellular granules often under conditions of metabolic stress due to a limited supply of essential nutrients. The properties of the PHAs are similar to those of polyethylene and polypropylene and can hence repPolyhydroxybutyrate (PHB) is a homopolymer belonging to the family of biopolyesters, polyhydroxyalkanoates (PHA) produced by different bacteria and archaea as intracellular granules often under conditions of metabolic stress due to a limited supply of essential nutrients. The properties of the PHAs are similar to those of polyethylene and polypropylene and can hence replace these fossil based poly
Synchrotron radiation sources have greatly contributed to the progress in many fields of science. The development of the storage ring technologies has made possible to obtain very low emittance electron beams, which together with the use of undulators allow guiding a very high photon flux into a very small spot required by the experiments. Development of the sources has been accompanied with equa
Global environmental issues concern a growing number of people and businesses are expected to communicate efforts towards environmental sustainability. Due to the controversial nature of its business practices and contribution to environmental problems, the oil industry holds a poor reputation and is considered to have a special need to communicate their efforts towards more sustainable business p
Högerpopulismen är på frammarsch i Europa, nu med en mer omfattande propagandaarsenal än någonsin, i vilken det senaste vapnet är de allt mer populära opinionssajterna. Uppsatsen undersöker hur narrativ konstrueras i högerpopulistiska opinionssajters nyhetstexter och hur dessa förändras över tid. Fallet består av 26 nyhetsartiklar publicerade på den svenska högerpopulistiska opinionssajten, Avpixl
Everybody involves stress in everyday life but not everyone handles it well. According to World Health Organization, stress and stress-related disorders are growing and in Sweden these disorders are considered serious public health problems. In this project, I am focusing in finding the way to help people decrease their stress. I developed a product that guides users to deep breathing. This object
Quantum Cascade Lasers (QCLs) can be designed to emit radiation in the Terahertz (THz) range. For these frequencies, which are faster than electronics and slower than infrared light, there are currently only few devices facing a wide potential of applications. The realization of room temperature operation of THz QCLs would enable practical use in e.g. spectroscopy and public safety. The question i
In today's data driven society the world is at a point of information overload. As people rely on Google for information and other platforms such as Netflix and Spotify for entertainment, the need for relevant filtering of content has never been higher. As a result, recommendation systems have seen a great surge in demand. One can divide the space of recommendation algorithms into primarily tw
Vertical agreements cover a wide range of supply and distribution agreements such as exclusive and selective distribution, franchising and agency agreements. Business practice is filled with vertical agreements, and sooner or later any practicing lawyer with a client doing business in or with the EU is likely to be asked to advise on the admissibility of certain restrictions of competition which a
Summary: Floodwater mosquitoes occur in temporary flooded areas and can cause tremendous nuisance in the near and far surroundings. In the Nedre Dalälven region in Central Sweden, mosquito control is based on application of the biological larvicide Bacillus thuringiensis israelensis (BTI) by helicopter. Precise mapping of the floodwater mosquito breeding sites, a prerequisite for successful BTI tr
The dramatic shifts that occurred to the Chinese economy in the recent decades led to the emergence of companies that have fulfilled the internal market needs and now try to compete on the global level. Among others, Chinese automotive industry is currently struggling to establish its products in the markets of developed countries; however, the results are modest due to low level of technological
