SAMMANS?TTNING AV MAKROALGER I SVENSKA ?LGR?S?NGAR eDNA sp?rning och klimatf?r?ndringar
The aim of my bachelor?s thesis is to investigate, through a literature review, changes in the
distribution of filamentous algae as well as the general species composition of macroalgae
and diatoms in Swedish eelgrass meadows. I have also studied the possibility of tracking
these algae and diatoms in eelgrass meadows using eDNA methodology. The focus has been
on linking these changes to climate change factors such as eutrophication, temperature
increase, and anthropogenic emissions, and how these affect the health of eelgrass meadows
and their ecosystem services, such as a carbon sink and biodiversity support.
The results show that filamentous algae have increased markedly in coverage in Swedish
coastal areas between 1980 and 2021, especially in sheltered bays, indicating that altered
environmental conditions favor these fast-growing species. Genetic tracking using eDNA
demonstrated that there are functional primers for many species, particularly among brown
algae and red algae, whereas green algae require more specific primers due to greater genetic
variation.
En studie om miljöklassningssystemet CEEQUAL : Civil Engineering Environmental Quality Assessment and Award Scheme
Syftet med examensarbetet är att främja den hållbara utvecklingen i anläggningssektorn. Målet med rapporten är att visa hur miljöklassningssystemet CEEQUAL kan förbättras samt hur användningen kan främja hållbar utveckling i mark och anläggningsprojekt i Sverige. CEEQUAL är ett miljöklassningssystem inom infrastruktur och anläggning som har utvecklats i Storbritannien av Institution of Civil Engineers. I examensarbetet har följande frågeställningar undersökts: Hur fungerar CEEQUAL i praktiken? Vad är den svenska erfarenheten från användningen av CEEQUAL? Hur kan anläggningssektorn förbättra miljö/hållbarhetsarbetet genom miljöklassning med CEEQUAL? Hur kan man förbättra miljöklassningssystemet CEEQUAL? Frågorna har besvarats genom metoderna litteraturstudie och dokumentanalys men även genom intervjuer med olika aktörer inom anläggningsbranschen. Denna rapport innehåller en kort sammanfattning av vad hållbar utveckling betyder och en fördjupning inom miljöklasscertifieringssystemet CEEQUAL samt dess användning inom anläggnings- och infrastrukturprojekt. En jämförelse mellan CEEQUAL, de 16 nationella miljömålen och Kretsloppsrådets mål har också utförts för att se om de behandlar samma miljöområden. En certifiering sker i flera olika steg. En certifiering genomförs av en utbildad assessor som bedömer och ger poäng på svaren av frågorna som återfinns i CEEQUAL:s manual.
Manligt och kvinnligt för barn: Könsroller i 1980- och 2000-talets svenska bilderböcker
The aim with this masters thesis is to investigate how gender is presented in Swedish picture books, in order to give librarians and other actors in the field knowledge about what kind of books they supply impressionable children with. I investigate if and how the changes concerning gender-equality in the Swedish society during the last 25 years are reflected in childrens literature, and compare how men and women are portrayed in four books from the early 1980s with four books from the 2000s. My study is delimited to three aspects of character formation, introduced by Maria Nikolajeva: description of psychology, actions and relations to other characters. It is carried through by consultation of Yvonne Hirdmans theory of how men and women are held apart and that the man in this relation constitutes the norm as well as Nikolajevas list of typical male and female characteristics. By reading and interpreting the chosen books, I analyse both text and pictures.
Vattenapeteorin: Paradigmskifte eller pseudovetenskap?
The Aquatic Ape theory was first formulated by Alister Hardy in year 1960. All from the beginning the theory has been criticized, ridiculed, ignored and a source to strong feelings in the anthropological community. The purpose of this essay is to investigate why the Aquatic Ape theory is so controversial and why it is understood so differently by scientists. After interviews with Swedish scientists and the general community, and after reading of anthropological books, I have tried to show that the aquatic ape-coldness depends on it challenging nature against the anthropological paradigm, which describes human beings as strong, hunting creatures who can live in any environment. The Aquatic Ape theory - on the other hand - picks out one of all these environments and says: "here has our evolution occurred: we have been aquatic apes".
Beskrivningar av operationssjuksköterskors upplevelser av att känna sig förberedda inför det nya yrket efter avslutad specialistutbildning : - kvalitativ intervjustudie
In this study, emphasis was situated around pupils? expectations regarding body shape and physical proficiency among teachers within the subject of physical education. Additionally, possible outcomes of failure to uphold such demands were put in relation to aspects of legitimacy. To enable such study a qualitative study including semi-structured interviews was conducted and carried through, involving six pupils in the third grade of upper secondary education. The pupils were mainly selected through a convenience sample with.
Barnbiblioteksarbete ur ett genusperspektiv
The aim of this masters thesis is to investigate how childrens librarians deal with gender issues in their work when acquiring and mediating books to children, and how reviews in Bibliotekstjänsts Sambindning can be of help in this aspect. The thesis focuses on children between 6 and 12 years of age and their reading of fiction. Four interviews with childrens librarians and an examination of reviews in Sambindningen have been carried out. The reviews were examined both by finding out with what frequency gender issues are dealt with and by studying 20 childrens books from a gender perspective, comparing my judgement with the one they got in the reviews. The examination of Sambindningen showed that the reviews therein only sporadically bring up gender issues.
Design och implementering av ett webbaserat personalhanteringssystem
Quickmatch is a company that recruits students to other companies that need temporary workers. Today all administration is done by hand, which is very time demanding and therefore inefficient. Employees send assignment reports by e-mail about the working hours and breaks to the administration office. Since these reports are handled manually, there is a great need for an automated system that makes the company more scalable.The purpose of this work was to solve the defined problem, i. e.
Skolan i demokratisk utveckling : Förändringar i lärar- och elevrelationer
This work is designed to monitor developments in the relationship between teacher and student in the school environment, but also outside, from the 1950s until today. The survey was based on four interviews with teachers in the same age, and based on their life stories. Their experiences range from student to novice teachers and a long working life until retirement. In addition, all four children has a parent perspective. The following issues have been focused: 1.What factors have been crucial in teaching elevrelationens development from the 1950s up to today? 2.
Kalkyl för logistikkostnader; från leverantör till förbrukningsplats
The globalization that has occurred during the last few years has made it more important for companies to have a well-functioning logistics system. Customers demand more options, which lead to an increased flow that creates greater demand regarding packaging and transports. Diverse logistics costs are nowadays a substantial cost for many companies. Therefore, more effort is aimed at optimizing transportation to lower these costs.The purpose of this project is to create a user-friendly calculation of logistics costs that illustrates how the costs vary, depending on how the flow is structured. This is done by examining which aspects that affect the total logistics costs and by mapping which aspects that should be included in a calculation of the logistics costs.Literature studies have been carried out parallel with empirical studies at Scania's production unit, MC, in Oskarshamn.
Ut ur Östersjön genom vassen : beskrivning av övergödningsproblematiken samt optimering av en reningsmetod genom skörd av vattenväxter
This study is based on AgroSeas business idea from environmental problems to valuable resource, with the objective to optimize a method to purify the already eutrophicated Baltic Sea by harvesting water plants, mainly reed. The nutrients will then be recirculated to arable land through residues from biogas production. The amount of nutrients that can be removed by harvesting the biomass
depends on the amounts of biomass and the nutrient content of it, which in turn is strongly dependent on the nutrient concentration of the surrounding water. Vegetation suggested in the study for an effective nutrient uptake is helophytes: reed, cattails, reed canary grass, reed sweet
grass in shallower water and lemnoideaes: duckweed and nymphaeids in the deeper parts.
Competitive species has high purification ability but requires regular maintenance to avoid channeling and overgrowth. Regarding time and method of harvest, effectiveness may be improved by: harvesting plants above the water level and after flowering, a border is kept, harvesting twice a season, a bigger machine and a regular maintenance.
This literature has illuminated a major environmental problem and it has been suggested
optimizations for a method for cleaning the Baltic Sea through harvesting water plants, but to get a
definite answer for the optimal method for each site tests should be carried out, this because many
factors determine to what is suitable for each, specific environment.

The aim is achieved byexamining the language-use and identifying discourses in the debate.
Fo?rutsa?ttningar fo?r elektrifierade lastbilar med eHighway inom svensk gruvindustri : En ja?mfo?relse av olika transportslag mellan Mertainen och Svappavaara
The Swedish government has a goal of achieving a fossil-free vehicle fleet in 2030. Heavy transport constitutes a significant part of Sweden's transportation sector and the vehicles are driven almost exclusively by fossil fuels. Siemens has developed eHighway, a concept for electric road systems enabling electrification of trucks, in order to reduce the environmental impact of heavy transports. This study aims to investigate the potential that eHighway has on transporting iron ore from the mine of Mertainen to a processing plant in Svappavaara. Electrified trucks are compared with conventional trucks, and diesel and electric trains.The evaluation was made with respect to energy consumption, environmental impact, and cost.
Poker eller patiens? Multilaterala förhandlingar i Europaparlamentet; en explorativ studie av förhandlingskulturen i Europas folkvalda parlament.
Since the Maastricht Treaty the European Parliament has gained competence in the decision-making process and the Parliament is today one of two decision-making institution, next to the Ministers of Council. In this study the main focus has been to shed light over the negotiation culture within the European Parliament, which up till now has been a neglected research area. This is of great significance because the internal negotiations in the European Parliament decide the external negotiation position with the other institutions.After face-to-face interviews with MEP:s and assistants I have been able to identify certain characteristics to create an understanding of the negotiation culture in Europe's elected Parliament. The negotiations are oriented towards a problems-solving approach and the prevailing apprehension is consensus-based negotiations instead of the existence of political blocks. The committees are stronger than the European party groups, which further encourage negotiation.

Det som andra kallar en kliché kallar vi för en klassiker
Abstract:Perennials in public areas have during the latest decades been more and more popular. This group of plants has become a more accepted komponent when creating pleasant public places, and people begin to see the functional aspects. Perennials do also give a colour- and senceexperience in a more detailed way than can be achieved with only trees and shrubs. One of the ojects of this essay is to give more examples of motives for using perennials in urban areas.Having in mind the increasing use of perennials, you can expect a growing need for better understading of how to create successfull perennial plantings. In spite of the increasing interest it is hard to find any written information in this subject.
