Amfibier i dagvattendammar — vad vet vi? Bor du i en stad men har hört grodor kväka under sommarmånaderna? Då är det inte osannolikt att de satt och ropade på varandra i en dagvattendamm. Amfibier brukar kanske inte alltid förknippas med stadsnära miljöer, men förutom att bidra med vattenrening och flödesutjämning, så kan dagvattendammar agera nattklubb och barnkammare. (För att inte tala om inseAmid an anthropogenic sixth mass extinction, amphibians are among the most threatened organism groups. This can be explained largely by the loss and fragmentation of natural wetlands due to agricultural activities and urbanisation. Stormwater retention ponds are designed both to provide flood control and to collect and purify runoff from impervious surfaces but could also serve as amphibian habita

The study investigates the design of kené, a geometrical pattern originated in the culture of Shipibo, in relation to Gilles Deleuze and Félix Guattaris’ philosophical term rhizome. Kené is, besides the nowadays more influential part of the Shipibo material culture of handicraft, historically connected to healing practices which includes the hallucinogenic brew ayahuasca. The thesis is an autoethn

This master thesis examined the microstructure after heat treatments in stainless steel, two conventional stainless steel (304 and 316) and two novel high temperature stainless steel. These stainless steels are for the use in high temperature heat exchangers for extended temperature range. The positive characteristics in stainless steel are inversely correlated to grain size, characteristics such

Plant-insect interactions play a crucial role in the evolution of the coevolving web of life, shaping local interaction networks and moulding the diversity and the evolutionary history of two of the most diverse groups of organisms on earth. The interaction between Lithophragma bolanderi (Saxifragaceae), which presents a geographic mosaic of ploidy levels, and the pollinating floral parasite Greya

Conventional urban planning doesn’t fit anymore the complexity of new urban challenges (heat island effect, biodiversity loss, human health issues). Instead, alternative methods must coexist with existing strategies for municipalities to be more flexible to changes and stay innovative. This research advocates the use of vacant land in cities for urban agriculture. As a nature-based solution, vacan

Dosan challenges the current norms and preconceptions of light switches in a home environment by creating impactful and joyful moments into an otherwise repetitive action. Technological advancements have led to an increased lack of physical interaction and tactile feedback, therefore it is important to consider what is replaced and what gets lost when new innovative technology is introduced. Dosan

The autonomous truck is gradually making its way onto our roads, and the elimination of the truck driver implies a substantial social-technical transition for logistics companies. Specifically, transport managers who work closely with the drivers on a daily basis, will potentially see a significant change at work. The implementation of the autonomous trucks in logistical companies could cause fric

Detta examensarbete utfördes på företaget Devex Mekatronik i Lund som under arbetets gång köptes upp av företaget Etteplan. Målet med det här examensarbetet var att vidareutveckla och förbättra ett låssystem till ett medicinskåp med tillhörande databas. Devex Mekatronik hade påbörjat en egen lösning på problemet men ville utveckla ett fullständigt system som fungerade på det sätt de hade tänkt sig

Vårdnadsöverflyttning enligt 6 kap. 8 § föräldrabalken, syftar till att skydda barn som under en längre tid levt i familjehem från att ryckas upp från sin trygghet och nya familjemiljö. Syftet med denna uppsats är att undersöka förutsättningarna för vårdandsöverflyttning av vårdnaden om barn till familjehemmet de blivit placerade i efter beslutande om vård enligt 2 § LVU. Sedan analyseras vårdnadsCustody transfer according to 6:8 Parental code (föräldrabalken) aims to protect children who have lived in a custody home for a long period of time from being taken from their new home. This assignment aims to examine under what circumstances a custody transfer can be made from the child’s biological parents to the custody parents after the child have been placed in a custody family in accordance

Den 23 september 2020 lanserade EU-kommissionen den nya asyl- och migrationspakten, där fem nya lagförslag presenteras, som bland annat syftar till att förhindra att asylsökande utan tydliga asylskäl får resa in i Europeiska unionen (EU). För att uppnå det här målet föreslår EU- kommissionen att inrätta en fas före inresa, som kommer att bestå av en fem-dagar lång screening av alla tredjelandsmedbOn the 23 September 2020 the European Commission launched the Pact on Migration and Asylum, introducing five legislative proposals, which inter alia aim at ensuring that only people with clear protection needs enter the European Union (EU). To reach this objective, the European Commission introduced a so-called pre-entry phase, consisting of firstly, the proposed screening procedure, a five-day pr

Detta examensarbete genomfördes i samarbete med AFRY och deras kund Homezan som specialiserar sig på design av möbler producerade i naturmaterial. Bakgrunden till arbetet myntades genom företagets önskan att utöka deras produktsortiment med hallmöbler. Därmed har detta examensarbete fokuserat på att utveckla ett hallmöbelkoncept med fokus på att identifiera företagets målgrupps förvaringsbehov. UtThis Master Thesis project was performed in collaboration with AFRY and their client Homezan, who specializes in home furniture design produced in natural materials. The project scope emerged from the company’s request to expand their product assortment to hall furniture. To solve this request, this Master Thesis project a hall furniture concept have been developed with focus on identifying custom

This thesis considers an investigation into the possibilities of creating a reasonably accurate multiscale material model for paperboard, with geometry based on X-ray scans of small paperboard samples. The modeling takes place in the software Multiscale Designer by Altair Engineering Inc. A representative volume element (RVE) is used to capture the X-ray geometry and represent macroscopic mechanic

Microcystis blooms are implicated in toxic algal blooms worldwide due to the production of toxins microcystins. Blooms have caused poisoning of humans and other animals, and annually contribute to economic loss. The biological role of microcystin synthesis by the genus Microcystis remains an unanswered question. Consequently, the factors that select for microcystin producing (toxic) phenotypes ove

En grundläggande princip inom straffrätten är in dubio pro reo. Principen innebär att åklagaren bär bevisbördan i brottmål och att domaren i tveksamma fall ska döma till den tilltalades fördel. Denna princip ligger till grund för oskyldighetspresumtionen som innebär att en tilltalad ska presumeras vara oskyldig till motsatsen bevisas. Oskyldighetspresumtionen har indirekt tillämpats i svensk rätt A fundamental principle in criminal law is in dubio pro reo. The principle imply that the prosecutor bears the burden of proof in criminal cases and that the judge, when in doubt, must rule in favor of the accused. This principle is the basis for the presumption of innocence, which means that a defendant must be presumed innocent until proven guilty. The presumtion of innocence has been indirectly

Effects of TGFβ on the extra cellular matrix and its architects the fibroblasts Fibroblasts are the main architects of the extra cellular matrix (ECM), the non-cellular structure, surrounding the cells throughout the body. The ECM and fibroblasts are constantly communicating with neighboring cells, and an imbalanced ECM state can have detrimental impacts in the organism. In diseases like cancer,

A Power Amplifier (PA) is an essential electronic component in all microwave and millimeter-wave applications and, more specifically, in any transmitting system where the level of input power signal needs amplification to the desired level.Linearity and high efficiency are of utmost importance in PAs. However, high-efficiency PAs tend to be non-linear, and PAs working in the linear region might ha
