Increasing global temperatures have been shown to advance the breeding phenology of migratory birds, not least in temperate regions, causing birds to adapt the timing of other life-history events such as molt. At high latitudes, summers are shorter, and the birds must complete their post-breeding molt in the few weeks available before the conditions in the breeding site become unfavorable. I exami
Animal migration is a widespread phenomenon that has evolved repeatedly in a diverse set of taxa. To cope with migration, individuals express a large variety of specialized behavioural adaptations, that rely on efficient sensory systems for extraction of relevant external information. Many behaviours are visually guided, such as foraging and predator avoidance, and most migratory animals possess e
Vägarna i Sverige är totalt cirka 57 000 mil långa. Av dessa anses cirka 43 000 mil vara tillhöriga enskilda väghållare, det vill säga någon annan än offentliga aktörer så som stat eller myndighet. Vägar har länge haft en stor betydelse ur ett flertal aspekter och det har alltid funnits ett stort intresse av att vidhålla ett gott infrastruktursystem. Bestämmelser om vägar fanns det redan i de äldThe aim of this paper is to improve the management of joint facilities and private roads. This was done by identify and investigat different problems connected to the private road organisations, formed through the regulation of joint facility and associations connected to them. One aspect of the investigation was if the area of included land connected to one joint facility had grown in size. By st
Bakgrund: Med anledning av Barnkonventionens inkorporering i svensk lag är det idag högst aktuellt att undersöka och diskutera hur barn upplever att de ges möjlighet att vara delaktiga i sin vård. Barns delaktighet bygger på en god kommunikation och relation till hälso- och sjukvårdspersonal. Trots föreskrifter om att barn bör vårdas på avdelningar avsedda och anpassade till dem, förekommer det re
Den här studien undersöker en grupp musikelevers improvisatoriska val över dominantackord som leder till tonika i improvisationer över II V I-progressioner i dur. Studiens fokusområde motiveras av den höga andel II V I-progressioner som används som musikaliska byggstenar i genrer där improvisation förekommer i hög grad. Även om det inte ligger inom räckhåll för den här studien att undersöka kausalThis study focuses on a group of music students’ improvisational choices over the Vchord leading to the I-chord when improvising over major II V I chord progressions. The raison d'etre for this study is the high number of II V I-progressions being used as musical building blocks in genres that have improvisation as an integral part. Although it was not within the scope of this study to establi
Bakgrund: Människors livsstil och hälsa innan befruktning kan påverka graviditet, barnafödande och fostrets utveckling och välmående varför prekonceptionell hälsa och vård är viktig för alla individer. Barnmorskan arbetar med reproduktiv, perinatal och sexuell hälsa men möter sällan pojkar och unga män i sitt arbete. Skolsköterskan har därför föreslagits som lämplig att informera pojkar och unga m
Rapidly changing environments across the globe pose challenges for organisms to either adapt or risk extinction. High rates of gene flow are expected to prevent populations from adapting to their local ecological environments, but an increasing number of studies show that even at small geographical scales, natural or sexual selection can counteract the homogenizing effect of gene flow. Here I show
Over the last century, Swedish forests have undergone rapid land-use change due to intensification of management practices for timber production and the introduction of monocultures, which have resulted in considerable habitat loss and negative impacts to biodiversity. Insects form a significant component of forest biodiversity, yet forest-dwelling pollinators remain understudied, and little is kn
I Europaparlamentets och rådets förordning 2018/844, sätter EU krav på sina medlemsländer att skapa strategier för att uppnå energieffektivisering i byggnads-sektorn för att nå de mål som satts upp av FN i Parisavtalet. En stor del av byggnadsbeståndet utgörs av äldre byggnader och dessa byggnader har ofta allt för höga energibehov. För att arbeta mot FN:s mål, finns det ett stort behov av energi-The purpose of this master thesis was to examine what kind of energy efficiency measures that could be applied on older buildings and whether they could be profitable investments. In order to be able to calculate the relative energy saving effect of the measures, a specific building has been chosen, located in Malmö, southern Sweden and was built in the 1880. Different kind of energy efficiency
An antenna is one of the most fundamental elements of wireless communication systems. The radiation behavior of antennas is characterized with the aid of the farfield radiation pattern. In this thesis, a near-field antenna measurement system is designed to predict the far-field pattern of antenna operational frequency 28 GHz and 39 GHz. The near-field measurement system operates by measuring ma
The industrial sector in Sweden accounted for 38 percent of the country’s total energy consumption in 2019. As the world’s focus has shifted drastically on energy consumption, the industry sector’s has as well due to energy initiatives and government-driven regulations. The energy issue is currently of great relevance for energy-intensive industries where enormous potential remains due to factors
Is the general perception that Swedish news always conveys a true picture of reality and that the news is always credible? National security and military threats are today an essential part of the security policy agenda. The nature of the world around us has changed significantly in recent months and Sweden's security policy is directly affected by developments in the world around us. The rap
The aim of this thesis is to further develop the understanding of how different parameters related to the gasket groove of a heat exchanger affect the mechanical performance of the product. Three different parameters with two different gasket materials were evaluated. Comparisons between the parameters where mainly made in terms of contact- and leakage pressure but phenomena related to factors suc
The Swedish armed forces have struggled with recruitment of military personnel for several years. Despite the facts that the military units have equal opportunities to succeed in recruitment, some regiments do better than others. This may be due to difference of the sub-cultures within each military unit. This study examines whether there is a connection between personnel supply and cultures in mi
This essay provides an insight into the situation in Israel today linked to the initial plan from 1947, on the division of the land area into a Jewish part and an Arab part. The area is characterized by armed conflicts both historically and in modern times. Four major Arab-Israeli wars have raged since the declaration of the state of Israel in 1948. Unrest is still raging along the Israel-Gaza-Wes
