The Crevice - A theater in the open air on the coast of Portugal strives to prove a link between man made and natural formations. I marvel why the development of our human civilization keeps being branded as artificial with a negative connotation. I believe our built habitat is commonly considered somewhat less natural than bird’s neatly constructed nests or polar bears burrowing into snow and r

Insects can be mapped using a method called Scheimpflug Lidar (LIght Detection And Ranging). Sending out light in the near infrared range and detecting the backscattered echo, it is possible to resolve flying organisms in range and time. Insect observations can be distinguished from the background signal through adaptive thresholding. The detected signal will contain two components; one from lig

The main purpose of this thesis is to present and analyse the Swedish sixteenth-century Catholic priest Andreas Servius’ prayer book Någre Christilige och Catholische böner printed in the Silesian city of Neisse year 1593. The general questions of the study are: which where the main sources of the prayers found in this prayer book? What characteristics typical for the period’s piety can be found i

According to the Environmental Protection Agency (2016) food production has a big impact on the climate, and a big part of the food gets wasted as garbage. About 91% of the food that the stores waste is still eatable (Naturvårdsverket, 2014). The government has set a goal to reduce the food waste with 20% until 2020 in comparison to 2010. In present days there’s a lot of research on how to maintai

With the increase in computational power, deep learning algorithms have become an active field of research over the last 7 years. These data-driven machine learning algorithms have produced good results in many applications, image analysis being one of them. Today, many image analysis tasks in the medical field are done manually, taking valuable time and effort from professionals. Automating some

In an uncertain future, flexibility and ability to adapt are recognized as important factors in avoiding errors, but also discover new ways of handling urban problems. This thesis examines how standardized wooden modules can be used to modify, manipulate and reinvent public space. It also investigates how flexibility in design could help to involve communities and individuals in reshaping and recy

The objective of this report was to investigate different types of glass when exposed to heat radiation from a typical fire in a dangerous goods carrier. The purpose was to evaluate if tempered glass could be used in facades instead of the more expensive fire resistant glass. Experiments were made in a cone calorimeter where different thicknesses of laminated, tempered and fire resistant glass wer

Huge amounts of greenhouse gases continuously released into the atmosphere is of large global concern. Carbon dioxide makes up a large part of released greenhouse gases. Especially the aircraft industry, which is experiencing a steady annual increase as air travel grows in popularity. This business sees 72% of all its combustion products in aircraft exhausts to be carbon dioxide. Swedavia, a compa

One of most ancient food preservation methods is freezing because there are not caused significant changes the sensory characteristics and nutritional value of foods. Last decade, have been made great steps for the optimization of freezing tolerance of fresh vegetables, fruits and species. Cold injury occurs when the cells are exposed to temperatures lower than 0oC. Cold injury is a consequence of

Recognizing when and how rapid evolution drives ecological change is fundamental for our understanding of almost all ecological and evolutionary processes such as community assembly, genetic diversification and the stability of communities and ecosystems. Generally, rapid evolutionary change is driven through selection on genetic variation and is affected by evolutionary constraints, such as trade

Predation is one of the key ecological mechanisms allowing species coexistence and influencing biological diversity. However, ecological processes are subject to contemporary evolutionary change, and the degree to which predation affects diversity ultimately depends on the interplay between evolution and ecology. Furthermore, ecological interactions that influence species coexistence can be altere

A tumour grows when the total division (birth) rate of its cells exceeds their total mortality (death) rate. The capability for uncontrolled growth within the host tissue is acquired via the accumulation of driver mutations which enable the tumour to progress through various hallmarks of cancer. We present a mathematical model of the penultimate stage in such a progression. We assume the tumour ha

Predator-prey interactions heavily influence the dynamics of many ecosystems. An increasing body of evidence suggests that rapid evolution and coevolution can alter these interactions, with important ecological implications, by acting on traits determining fitness, including reproduction, anti-predatory defence and foraging efficiency. However, most studies to date have focused only on evolution i

In an era of pervasive anthropogenic ecological disturbances, there is a pressing need to understand the factors that constitute community response and resilience. A detailed understanding of disturbance response needs to go beyond associations and incorporate features of disturbances, species traits, rapid evolution and dispersal. Multispecies microbial communities that experience antibiotic pert

Increasing body of experimental evidence suggests that anticancer and antimicrobial therapies may themselves promote the acquisition of drug resistance by increasing mutability. The successful control of evolving populations requires that such biological costs of control are identified, quantified and included to the evolutionarily informed treatment protocol. Here we identify, characterise and ex

Mutation supply can influence evolutionary and thereby ecological dynamics in important ways which have received little attention. Mutation supply influences features of population genetics, such as the pool of adaptive mutations, evolutionary pathways and importance of processes, such as clonal interference. The resultant trait evolutionary dynamics, in turn, can alter population size and species

A popular idea in ecology is that trait variation among individuals from the same species may promote the coexistence of competing species. However, theoretical and empirical tests of this idea have yielded inconsistent findings. We manipulated intraspecific trait diversity in a ciliate competing with a nematode for bacterial prey in experimental microcosms. We found that intraspecific trait varia
