Kan microgeografiska anpassningar förklara fenotypiska skillnader hos den större kustflicksländan När sommaren äntligen anländer börjar det också myllra av liv, inte minst vid dammar där en massa små flygande insekter håller till. En av dessa insekter är den större kustflicksländan (Ischnura elegans), vilken är en av de vanligare arterna av flicksländor i Sverige. Idag hotas tyvärr många arter avRapidly 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

”Vi måste prata om Blåbär & Bin” Det senaste decenniet har den svenska skogen genomgått stora förändringar med ett alltmer omfattande skogsbruk, introduktion av monokulturer och förlust av naturliga habitat. Samtidigt pågår en minskning av vilda pollinatörer världen över, vilket hotar livsviktig matproduktion och riskerar att bidra till en enorm förlust av biologisk mångfald. I Sverige är 69%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

IL-27 och mikroflorans inverkan på Th1 celler i tarmen Tarmen är ständigt utsatt för främmande ämnen (så kallade antigener) från mat, smittämnen och mikrofloran. Därav, krävs det en balans mellan de inflammatoriska och anti-inflammatoriska processerna för att undvika tarmsjukdomar. T celler spelar en central roll i regleringen av denna balans och kräver hjälp från dendritiska celler (DC) för init

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

Human errors happen all the time, everywhere in the world. Most of the errors are corrected before there is an accident. But in a high risk organization such as the military there are often bigger consequences when an accident happens. This case thesis aims to investigate a connection between experience and the human factor complacency in the Swedish armed forces. It also aims to highlight complac

Stigande energianvändning och global uppvärmning har lett till en ökad efterfrågan av förnyel-sebara energikällor. Ett alternativ är att utnyttja avloppsvatten för att producera biogas. Avlopps-vatten kan därav ses som en resurs snarare än avfall. I biogasproduktion används anaerob ned-brytning där mikroorganismer bryter ner organiskt material till metan. Primär rening är första steget inom avlopThe global heating has resulted in rising temperatures and more extreme weather conditions around the world. In combination with increasing energy demands, this has led to an increasing demand of renewable energy. One option is utilizing the wastewater to produce biogas. There-fore, wastewater can be seen as a resource rather than waste. Biogas production is based on anaerobic digestion where micr

This case study seeks to understand why non-commissioned officers (NCOs) in the Swedish armed forces decides to leave the organization. The study uses two different theories; Herzbergs two factor theory which focus on work motivation and a theory called Job embeddedness which tries to explain voluntary turnovers and what makes employees stay or leave. The empirical material is gathered through dee

In the early 20th century liberalism had an upswing. New treaties were signed, and the everlasting peace had finally arrived. In the Far East, Japan was emerging from an agricultural society and making major leaps toward industrialization. They had huge demands in recourses like oil and steel. As an emerging power Japan wanted to compare themselves with USA, Great Britain, and Germany. Their imper

Åland's status as a demilitarized and neutralized zone has achieved customary status and is defended by all parties involved. The Åland solution was historically a way of disarming the risks of a militarized and fortified Åland in a way that all parties could accept. But at the same time, demilitarization means that the military threshold for an attack is low, which in itself creates security

Sweden is currently without a functioning system to secure the supply of food in crisis and war. After the Cold War, the security policy orientation was characterized by peace, disarmament and the dismantling of both civilian and military readiness capabilities. The former assessment that Russia could not pose a threat to Sweden and our neighbouring countries has recently fundamentally changed. Th

In this study, the reagent 3,5-dinitrosalicylic acid (DNS) and high-performance anion exchange chromatography (HPAEC) were used for carbohydrate characterisation. It was revealed that the DNS reaction is not exclusive to reducing ends as commonly thought, but rather that the reagent reacts with other parts of the carbohydrate molecules as well. HPAEC analysis was used to find how the product distr

The purpose of this Essay is to study whether Swedish Army Officers of today are less prepared for an armed conflict than their older colleagues. The study is a text analysis of Meir Finkel’s theory on Cognitive and Command Flexibility, Swedish military Doctrines and other relevant documents. A research report put together by Swedish Defence Research Agency examining the process of career developm
