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.

Lantbruket som energiproducent : tekniska, ekonomiska och miljömässiga förutsättningar för fjärrvärmeproduktion med lokalt skogsbränsle

A third party access to district heating networks has been proposed in Sweden, to increase the competition on the district heating market. Such third party access could create opportunities for the agricultural sector as an energy producer. This study describes the technical, economical and environmental prerequisites for a farmer cluster to build and run a heating plant, fueled with local wood fuel. The heating plant in the described scenario is 8 MW and will supply a village of 1000 houses, and is fueled with wood chips exclusively. Supplying a heating plant with fuel puts high demands on the logistics, since there need to be a continuous flow of fuel. In the scenario, wood residues from felling and thinning is stored in stacks in the forest, and a few times a year chipped and transported to a storage area at the heating plant. In the study, an estimation of the profitability has been made by estimating the cost of the investment, personnel, operating and maintenance costs and costs for the fuel and ash handling.

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".

Fysiologiska kvaliteter hos manliga tävlingscyklister och effekten av högintensiv intervallträning

Abstract Road cycling is well established and has always been described as a highly endurance sport. To be able to compete in such a demanding sport the physiology of the athletes needs to be greatly developed. This review will focus on high intensity interval training and its impact on the physiological characteristics of competitive road cyclists. The main difference between different levels of competitive road cyclists seems to be the capacity to maintain a high sub maximal power output over a long period of time in order to succeed. High intensity interval training, from 30 seconds to 5 minutes, leads to improved VO2peak, aerobic peak power and time trial performance.

Stegljud i två moderna universitetsbyggnader med trästomme : en utvärdering av enkätundersökningar och mätningar

Denna avhandling behandlar stegljudet i två trähus på campus i Växjö. Staden lyfts ofta fram som en bra förebild inom miljö- och klimatfrågor. Det kommunala fastighetsbolag som äger, förvaltar och bygger universitetets byggnader är intresserade av dessa frågor när nya hus ska byggas. De två senast byggda husen är byggda med trästomme, som anses vara ett bra miljöval. Framtida hus förväntas även de byggas med trästomme.

Wolf movement patterns and the distribution of moose kills : implications for human harvest?

Most studies regarding wolf (Canis lupus) predation on moose (Alces alces) have focused on the total annual consumption of moose within a wolf territory but few have tried to describe the spatial impact of wolf predation on a local scale. In this study I have analyzed wolf movement data, wolf predation, moose hunting statistics and moose hunter observations to investigate how wolf predation affects the human harvest of moose in Scandinavia. Since wolves prey on mostly juvenile moose during summer, analysis of their summer movement patterns is crucial to understand its impact on the human harvest later during autumn. In this study both reproducing (n = 45) and non-reproducing wolves (n = 12) reduced their movement range during summer to 66% and 67% of their annual movement range, respectively. Reproducing wolves increased their movement range from early to late summer while non reproducing wolves did not.

Gotländsk grönsaksodling : utvecklings- och tillväxtmöjligheter

A diet based on a bigger part of locally produced vegetables can contribute to decreasing Environmental impact and improved health. In Gotland horticulture has increased more than in Sweden in total during the last 15 years. To investigate possibilities for development of Gotland´s horticulture, the cultivation of potato, vegetables, fruits and berries was mapped through a questionnaire among growers. Interviews and a workshop with growers and reseller were conducted to investigate the interest and prerequisites for growing new crops. In total approximately 2340 hectares of potato, vegetables, fruits and berries were grown in Gotland in 2012.

Vi sitter tillsammans : Upplevelser av samhörighet och ledarskap i ett traditionellt kontorslandskap.

The office is the working environment in which an increasing proportion of the population spends their days . One type of office are open plan offices which are characterized by several people sitting together in the same room without spatial boundaries . The general discourse of this kind of offices is that they constitute an advantageous design that allows organizational changes without the need for redevelopment . From a work perspective, this office design is both criticized and acclaimed . Problems with noise is frequently reported in research which can lead to ill health.

Enhetschefers arbete inom äldreomsorgen

The aim of the study was to describe how managers at the eldercare system especially in nursing homes work to ensure high quality care. For this purpose, a qualitative method was used in this study and four managers at nursing home have been interviewed. Previous studies have shown that managers in some cases are restricted in their actions and that this may slow down the improvement of the care. At the same time the managers describe their work as demanding and diverse. They have a significant staff responsibility, meaning that they have to ensure the quality of care.

Riskhantering i svensk köttindustri : analys av slakt-, styckning- och charkföretag

The changes in the Swedish meat- and meat processing industry have been substantial in recent years. These changes will alter the business environment for many companies. In order to be prepared to face new threats and new opportunities, companies should be actively working on these issues. Risk awareness and by developing of risk management strategies companies can act quickly and effectively when the conditions changes. The objective of this study is to analyse whether and why companies in the Swedish meat- and meat processing industry use various forms of risk management strategies.

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. .

Valfrihetssystem enligt LOV : Ur ett biståndshandläggar- och organisationsperspektiv 

Sweden has one of the best elderly cares in Europe and the Swedish care work is also one of the best in terms of quality, compared to other European countries. In recent years, higher demands have been set on the care work and the number of privatizations of public services has increased. In 2009 a new law came into force, the Act on System of Choice (LOV) which increased individual?s right to a greater participation and a free choice in the selection of health and social care providers. This paper aims to highlight the impact of the law, system of choice.

Gruppdynamik : en social gemenskap

The purpose of this work is to create more knowledge about the teacher's perceptions of group dynamics and its impact on school activities. How do teachers opportunities and obstacles in order to influence group dynamics among students. The questions I have answered is how the teachers see the importance of a functioning group dynamics in school, how teachers work with group dynamics and how teachers describe the opportunities and obstacles for effective group dynamics. The method I am using at work is a qualitative research method that involves obtaining the teachers' own thoughts, feelings and experiences around the right questions. I have interviewed three teachers in primary schools in the county of Stockholm to find out their particular approach.

En studie om konflikten mellan företags affärsstrategi och CSR-arbete i lågprishandeln

A wish for a higher standard of living has driven the rate of consumption in Sweden. Mainfocus in business is on a higher growth and profitability where some companies use a lowprice strategy to win competitive advantage. The positive consumption pattern spiral is oftendiscussed in media, while criticism is limited and often refers to the environment. In order toreduce our ecological footprint we should consume more sustainably. More and morecompanies implement CSR (Corporate Social Responsibility) in their business strategy tobecome more sustainable.
