Bio-based binders have recently been introduced to reduce the dependence on fossil raw materials, which bitumen is produced of. Measurements with dynamic shear rheometer (DSR) and rotational viscometer (RVB) were performed on mixtures with bitumen and two different types of bio-based binders, namely Lignin 1 and Lignin 2. Parameters like softness point, viscosity and parameters used to evaluate ru
Participation in corporate accelerator programmes is considered a powerful tool for early-stage start-ups for operational go-to-market and strategic business development acceleration. With the COVID-19 outbreak, all the activities related to the corporate accelerators were forced to move online. However, due to the novelty of the phenomenon, the influence of switching the modality of corporate acc
Capacity shortages in electricity grids can impose significant costs on society due to missed investments in industry. Due to limited profit opportunities and long lead times, grid reinforcements are not a viable solution to the problem, which must therefore be prevented through efficient use of existing grid resources. Local flexibility markets can financially compensate electricity users to shif
In this Bachelor's thesis, a solution to the Dirichlet problem using Brownian motion is given. Brownian motion is constructed using Kolmogorov's existence and continuity theorems. Blumenthal's zero-one law and the strong Markov property in various formulations are proven. Using these results, a solution to the Dirichlet problem is given using Brownian motion. The cone condition which g
This study analyzes the return to schooling in 22 countries. More specifically, the effect on earnings of receiving a bachelor’s and a master’s degree is estimated by applying a propensity score matching approach on microdata. Unlike many other techniques, propensity score matching addresses selection bias to a higher extent making the estimates of the treatment effect on the treated more reliable
PAPR Credentials is the name of a not yet published credential scheme that provides conditional privacy for its users. This means that an administrator can choose to revoke a user's anonymity. Doing so, however, the administrator must broadcast her intention, as the success of the privacy revocation depends on the help of other users, since the administrator does not have access to sufficient
Where do the children learn? A crucial part of our social construction, education and its space, has changed and is adapting to new knowledge and studies to improve the quality of the learning process. Space should represent the values and growth of society. The changing mindset does not mean that we deny or forget theories, strategies and resources that we have developed throughout history, but
This paper studies whether the level of IPO underpricing is enforced by increased firm complexity. Evidence from a sample of 215 Swedish IPOs between 2010–2020 suggests that investor’s ex-ante uncertainty increases as issuing firms become increasingly complex. As a consequence, firms exhibiting complexity generally experience higher degrees of IPO underpricing. Moreover, we find support for our cl
A significant proportion of the diversity of species seen today are insects and their host plants, and the evolutionary mechanisms behind their radiation have long captured the interest of biologists. The peacock flies of the large genus Tephritis (Tephritidae) use different host plants in the family Asteraceae for their reproduction. There is variation both in use of host plant species and in the
Architecture is always intrinsically tied to place. Regardless of how architects choose to interact with and study it, the context our buildings are meant to inhabit is an important piece of the puzzle. As the world is getting more interconnected and geographical constraints are getting less important to the architectural profession, I am interested in how the creative process changes when assumpt
We study the impact of research and development (R&D) intensity on acquisitions in R&D intensive industries. First, we look at the impact of target R&D intensity on acquirer return to see if it is affected by acquisition premiums. Second, we study the impact of target R&D intensity relative to acquirer R&D intensity and look at whether this impact is affected when the companies
Målet med denna uppsats var att undersöka vilken bild av Frankrike som kulturproducent som förmedlades av svensk rikstäckande dagspress, i det här fallet Dagens Nyheter och Svenska Dagbladet, under år 2020. Genom att genomföra en kvalitativ innehållsanalys av samtliga recensioner av fransk kulturproduktion publicerade i de båda tidningarnas kulturdel under det valda året ville jag få fram utrymmetThe goal of this thesis was to conduct a study in what image of France as a cultural producer that was mediated by the Swedish national press, in this case Dagens Nyheter and Svenska Dagbladet, during 2020. By implementing a qualitative content analysis on all of the reviews on French cultural production published in the chosen newspapers’ cultural section throughout the year, I wanted to examine
Entrepreneurial Passion has been directly and indirectly related with positive outcomes such as improved self-efficacy, persistence, and venture performance. However, an underexplored concept within entrepreneurship research is Team Entrepreneurial Passion, and to our knowledge there is no research on the interplay between Entrepreneurial Education, individual Entrepreneurial Passion and the emerg
