The objective of this work was to investigate whether there are differences between commensal and non-commensal populations of spiny mice (Acomys spp.). There is a good evidence that some populations of Acomys cahirinus have been commensal since the time of ancient Egypt, that is for at least 3,500 years. Therefore, it could be expected that some adaptation for a commensal way of life have evolved. To find out, I tested twelve populations of spiny mice in two types of open field test - a vertical test and a hole board test. In the vertical test, a wire mesh was added and offered to spiny mice to climb on. Since human settlements represent an environment with a new predation pressure as well as new hiding opportunities like those in heights above the ground, I hypothesized that commensal populations of A. cahirinus would (1) explore less on the ground and (2) prefer to spend more time on the wire mesh than the non-commensal populations. Results supported the first hypothesis as in both tests commensal spiny mice spent less time exploring on the ground than other populations. The second hypothesis, however, was not supported - all populations showed approximately equal interest in the wire mesh and commensal spiny mice did not spend more time on it compared to the others. Nevertheless, an overall...

Today construction industry is building higher and more complicated constructions than ever thanks to the advancements in materials, technical knowledge and methodologies. One important material is concrete, which has been used to create impressive architectural marvels. This dissertation aims to examine the differences between climbing and slip formwork systems for tall concrete structures that require several pouring steps in height. The main differences noted between both systems are formwork configuration, assembly and cycling of the formwork and climbing elements, price and quantity of material, labor required, the quality of the finished structure and safety during construction. A case study was investigated with the help of formwork supplier PERI Sverige AB and nordic contractor PEAB AB regarding a 20,5 meter high reinforced concrete silo located in a mining complex in Kiruna, Sweden. Through a review of the existing literature in the subject, interviews with experts in the topic and the outcome from the project case study, the results shows that while the SCS climbing system from PERI Sverige AB required more working days compared to a slip formwork system, it was chosen as a more appropriate solution for this project in combination with the crane at the jobsite, due to the amount of labor required, safety and overall cost of it. In conclusion, the selection of the SCS climbing system as formwork system proved to be the most adequate solution for the case study when critical aspects such as assembly and cycling of formwork, price and safety were evaluated.

Mountain climbing is a leisure activity being performed mainly in a natural environment. In our country can be found preponderance of convenient places for doing this kind of sport in the Specially Protected Areas. The basic legal regulation governing the performance of climbing in the Czech republic is the Act of Nature and Landscape Protection. This paper investigates opinions of Administration of Protected landscape Areas employees on climbers and on mountain climbing generally. It also investigates possible effects of mountain climbing according to the view of particular employees. For this investigation I have chosen a qualitative strategy of sociological research.

Achieving optimal performance of a database can be crucial for many businesses, and tuning its configuration parameters is a necessary step in this process. Many existing tuning methods involve complex machine learning algorithms and require large amounts of historical data from the system being tuned. However, training machine learning models can be problematic if a considerable amount of computational resources and data storage is required. This paper investigates the possibility of using less complex search algorithms or evolutionary algorithms to tune database configuration parameters, and presents a framework that employs Hill Climbing and Particle Swarm Optimization. The performance of the algorithms are tested on a PostgreSQL database using read-only workloads. Particle Swarm Optimization displayed the largest improvement in query response time, improving it by 26.09% compared to using the configuration parameters' default values. Given the improvement shown by Particle Swarm Optimization, evolutionary algorithms may be promising in the field of database tuning.

I en analys av Lidatorp, en mindre tätort i Nynäshamns komun, kom man fram till att aktivering av de kringliggande naturområde för rekreativa ändamål skulle ha en positiv inverkan på samhället både i form av välbefinnande och motion samt attraktion till området från regionen. Området runt Lidatorp-Björsta har på många sätt potential för friluftsaktivitet samt fungera som nod i ett större friluftssammanhang. Här passerar bland annat Sörmlandsleden och även föreningar såsom Ösmoscoutkår, Friluftsfrämjandet och Nynäshamns Brukshundsklubb saknar egna lokaler samt ett aktivt engagemang för sporter som klättring och paddling gör att ett center för friluftsliv och motion skulle vara ett önskat tillägg till området. Projektet ska bidra till att ge lokala medborgare, scouter, skolelever och sportintresserade nya möjligheter till ett aktivt friluftsliv i skolan eller fritiden. Ett klassrum i skogen samt en redskapsbank med cyklar, tält, camping utrustning, stormkök, kanoter, flytvästar etc. ska tillgängliggöra naturen och rörelse till fler. Mötesrum och lokaler för föreningsverksamhet ligger i anslutning för att göra byggnaden till en plats fylld av aktivitet hela dagen. Centret är menat att bli ett uppskattat utflyktsmål som vill främja intresset för att vistas och motionera i naturen strategiskt placerad med anknytning till pendeltåg från Stockholm och buss från Nynäshamn och Ösmo. Gestaltningen har präglats av att försöka tackla en svår terräng men samtidigt ha en försiktighet till landskap och natur där byggnaden ska relatera till och samspela. Programmet har styrt layouten av planen med huvudaktiviteterna som klättercentret (som öppnar upp för klättring på berghäll inomhus), kanothuset och samlingslokalerna som huvudnoder där terrängen både skapat utmaningar och möjligheter.  En annan huvudidé vid gestaltningen har varit att bevara en sorts känsla av en traditionell friluftsstuga trots ett stort program. Genom att leka med tanken om flera stugor sammansvetsade i en rad som sedan krängts och vridits till att följa terrängen likt en stig, har de skilda aktiviteterna i byggnaden länkats samman. Denna slingrande byggnadskropp har sedan lyfts upp på ben likt en varelse som vandrar uppför sluttningen den står på. Detta möjliggör för rumsligheter runt om och under byggnaden samt uppfyller önskan om varsamheten till landskap och natur. Den struktur som lyfter upp byggnadskroppen har inspirerats av de temporära surrade strukturer som oftast dyker upp vid scout- och friluftssammanhang där rep och slanor (stockar) brukas för att konstruera diverse sovplatser, torn, broar, matplatser och byggnadsverk. / In an analysis of Lidatorp, a smaller settlement in Nynäshamn municipality, it was concluded that activation of the surrounding nature area for recreational purposes would have a positive impact on society both in terms of well-being and exercise as well as regional attraction. The region around Lidatorp-Björsta exhibits significant potential for outdoor activities and can serve as a node within a larger sports and outdoor context. Notably, the presence of Sörmlandsleden and local associations such as Ösmoscoutkår, Friluftsfrämjandet, and Nynäshamns Brukshundsklubb, lacking their own premises, along with an active commitment to sports like climbing and paddling, underscores the need for a dedicated center for outdoor life and exercise in the area. This proposed project aims to provide local citizens, scouts, school students, and sports enthusiasts with new opportunities for active outdoor lifestyles during both school hours and leisure time. A classroom in the forest and an equipment bank stocked with bicycles, tents, camping equipment, canoes, life jackets, etc. will make nature and sports available to more people. The presence of adjacent meeting rooms and spaces for association activities enhances the vibrancy of the building, ensuring a constant buzz of activity throughout the day. The strategic location of the center, with convenient connections to commuter trains from Stockholm and buses from Nynäshamn and Ösmo, aims to establish it as a popular destination for excursions, promoting interest in outdoor activities and exercise in nature. The design has been characterized by trying to tackle a difficult terrain but at the same time being cautious towards the existing landscape and nature. The layout of the plan has been influenced by the program's requirements, with key activities such as the climbing center (providing indoor bouldering), the canoe house, and the meeting rooms serving as primary nodes that respond to both challenges and opportunities presented by the terrain. Furthermore, an important design principle has been to evoke the atmosphere of a traditional cabin despite the large-scale program. By conceptualizing the building as a series of interconnected cabins, adapted and contoured to mimic a forest trail, the distinct activities within the facility are seamlessly linked. This winding body is elevated on legs not unlike a creature ascending the slope it stands on. This allows for spaciousness around and under the building and fulfills the desire for cautiousness towards the surrounding landscape and nature. The framework that suspends the building is inspired by the temporary lashed structures commonly found in scouting and outdoor contexts where ropes and logs are utilized to construct various shelters, towers, bridges, dining areas, and structures.
