Effekten av arktiskt klimat på inre kvalitet hos bär

This project is a literature study with the hypothesis that Arctic climate has a positive effect on the Accumulation of metabolites in berries. Plant metabolites are often divided into primary and secondary metabolites. Primary metabolites such as proteins and nucleic acids are essential for cell function, while secondary metabolites are often non-essential, but have important functions regarding reproduction and survival. The berries mentioned in this project are from the families Ericaceae, Rosaceae, Elaeagnaceae och Grossulariaceae.The conclusion drawn from this literature study is that it is not obvious what favours Accumulation of metabolites in berries. Other factors aside from climate affect the production of secondary metabolites, such as time of harvest, cultivars and ripeness.

Ackumulation av CO2 och CH4 i istäckta boreala sjöar : Hur förändras ackumulationen i sjöar påverkade av avverkning jämfört med referenssjöar?

The aim of this report was to quantify the Accumulation of carbon dioxide (CO2) and methane (CH4) in ice-covered lakes in winter (October-March) during three consecutive years, and to assess whether the concentrations of DIC and CH4, as well as the ratio DIC:CH4 differs between years and between lakes affected by clearcutting and untreated reference lakes. Water- and gas samples were collected from four boreal lakes (two affected by clearcutting and two untreated reference lakes) located in Västerbottens inland in spring. The lakes were found to accumulate on average 91, 55, and 84 mgCm-2d-1 during winters 2012-2013, 2013-2014, and 2014-2015, mostly originating from CO2. The concentrations of DIC (autumn and spring) were higher in the affected clear-cut lakes compared to reference lakes for all years, including the reference year (2012-2013) before clear-cutting. No such difference was found for CH4 or the ratio DIC:CH4.

Födointagets betydelse för muskelglykogeninlagringen efter arbete hos häst och människa :

Glycogen is the storage form of glucose and is used by the skeletal musculature as energy both for intense and endurance events. The glycogen content in the horse?s middle gluteal muscle is more than 600 mmol/kg dry weight, and almost 400 mmol/kg dry weight in the human?s Vastus lateralis. In some special occasions, for example in competitions with several moments on following days, there is a need of a fast muscle glycogen resynthesis. The feed intake is of importance for the velocity of the resynthesis.

Sustainable phosphorus management of horse paddocks at Julmyra

Horse keeping is gaining an increasing interest in Sweden. During 2004 to 2010 the number of horses increased with 10 - 20 %, and was estimated to be 362 700 in 2010. Julmyra Horse Center (JHC), situated in Heby municipality, is a gated community for people sharing a large interest for horses and a vision of a sustainable horse management has been formulated. This study evaluates how the horse keeping of today at JHC, and how an expansion of the horse keeping may affect the risk of enhanced phosphorus load to the nearby lake system Vansjön ? Nordsjön.

Miljögifters exponering, ackumulering och effekter på immunsystemet hos husdjur :

The purpose of this literature review was to describe the paths of exposure and Accumulation of organic pollutants into the tissues of farm animals. Organic pollutants can be spread in the environment by air and rainwater. Farm animals can be exposed to these pollutants for example by eating soil or contaminated plants. Many of the pollutants can then accumulate in the fat tissues of the body because of their lipophilic character. Brominated flame retardants and perfluorolated compounds are both pollutants of current interest.

Ekologiska fotavtryck för koldioxidutsläpp för Stockholms län, Norrbottens län och Stockholms läns landsting : En kritisk metodgranskning baserad på kvantitativa data

Human existence and welfare depend on functional ecosystems. Ecosystems are critical to sustain life-support services for human well-being. One method that visualizes that humanity requires ecosystem services for resource consumption and assimilation of produced waste is ecological footprints. This study focuses on the ecosystem service carbon sequestering. A quantification of this ecosystem service showed the potential for Accumulation of carbon in different ecosystems in Stockholm and Norrbotten County for the years of 1995 and 2004.

Sambandet mellan alkohol och bukfetma

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: The relation between alcohol and abdominal obesityAuthor: Anna Eriksson och Karin EdenholmSupervisor: Fredrik BertzExaminer: Ingrid LarssonProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 30, 2013Background: Abdominal obesity is a part of the metabolic syndrome, which has a worldwideprevalence of 20-25 %. The problem with abdominal obesity is the Accumulation of visceraladipose tissue, which is an important risk factor for cardiovascular disease. Alcohol haseffects on metabolism, and can also lead to an increase in total energy intake; these twofactors can lead to an increase in Accumulation of visceral fat. Besides this there are studiesthat show that a moderate alcohol intake could be good for your health. The context gets morecomplicated since different studies have shown contradictory results concerning theassociation between alcohol, different types of alcoholic beverages and measurements ofabdominal fat.Objective: The objective of this article review is to assess the evidence of whether alcoholintake is associated with Accumulation of visceral adipose tissue, using the measurementswaist circumference (WC) and waist-hip ratio (WHR).Search strategy: The databases used in the literature study were PubMed and Scopus.

Den nyliberala staden : -Ett Kalmarperspektiv

Abstract Contemporary cities find themselves today in a fierce competition against other cities over company establishment and in -migration. In this competition, the city?s main objective is to become an attractive site of capital Accumulation.  As this happens, the pressure on the vulnerable groups in society increases, leading to a social geographic polarization. I have examined how the shift towards neoliberalism has affected a city on the fringe as Kalmar. How is the postindustrial urban space constructed? I found this important to analyze since it put two important questions in the light: For whom, and for which purpose do we build the city today? My questions have been:v  What are Kalmar municipality?s strategies to develop Kalmar?v  What are the results of this strategy in the urban space?v  What are the consequences of this strategy?The research has been a case study of the city of Kalmar with a qualitative deductive approach where David Harvey?s theories about the city in a capitalist system have been the underpinning structure.

Spårelement i Sveriges jordbruksmark : flöden, trender och fältbalanser

Field balances based on supply and removal of trace elements from the topsoil have been calculatedfor farms specialized in crop, dairy and pig production in Sweden. Today's field balances have beencompared with the field balances of 1990 in order to examine if, and then how, the situation haschanged. Studied trace elements are arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu),mercury (Hg), manganese (Mn), nickel (Ni), lead (Pb) and zinc (Zn).The balance calculations show that the stores of Cu and Zn are depleted with an average rate of -15% and -6 % over a 100-years period on crop farms when only commercial fertilizers are being used.The concentrations of Hg and Pb tend to increase in the topsoil on crop farms with more than 3 % forHg and with 2 % for Pb in 100 years. There is today balance between supply and removal of the traceelements As, Cd, Cr, Mn and Ni. In the south of Sweden, on crop farms with sugar beets in the croprotation, one can see a decrease in the concentration of Cd in the top soil by -6 % over a period of100 years.

Nedbrytning av propylenglykol i uppsamlingssystem för avisningsvätskor : En studie utförd vid Stockholm Arlanda flygplats

Deicing fluids based on Propylene glycol are used at Stockholm Arlanda airport to remove or prevent ice on aircrafts. The high oxygen demand of propylene glycol can cause oxygen depletion in rivers downstream from the airport if not collected. Mass balance calculations made by Swedavia indicate that the actual amount of gathered propylene glycol is underestimated. Suspicions that propylene glycol is degraded in the stormwatersystem designed to collect deicingfluids, called the B-glycolsystem, have to be investigated in order to establish with certainty that no propylene glycol in other ways leaves the B-glycol system.The purpose of this study was to determine if degradation of propylene glycol is present in the B-glycol system and also to estimate the extent of the degradation. Propylene glycols high biological oxygen demand can cause oxygen depletion in waters downstream from Stockholm Arlanda airport if not collected.

Miljöpåverkan av Cu från mjölkkors klövbad

Klövsjukdomen digital dermatit hos kor ger upphov till smärta hos djuren samt störningar i produktionen. För att förebygga och behandla klövsjukdomen används olika preparat, däribland CuSO4-lösning.Syftet med studien är att undersöka om och i så fall i vilken omfattning spridande av kopparförorenad gödsel påverkar Cu-halten i jordbruksmark.Studien genomfördes med provtagning av två oberoende jordbruksmarker där ett av områdena gödslas med kopparförorenad gödsel. Resultaten visar att jordbruksmark där förbrukad CuSO4 spridits med stallgödseln ger upphov till en signifikant ökad Cu-halt i markens översta lager, 0-25 cm.  .

Utveckling av substratmixen vid Mosseruds biogasanläggning : Substratkartläggning och rötningsförsök i laboratorieskala

The world?s growing need for energy together with a desire to ward off the worst consequences of global climate change has resulted in a never seen desire to invest resources in renewable energy sources. Biogas production through anaerobic digestion is one of those growing energy sources. In Sweden there are over two hundred plants that uses this biological process to break down organic substances while producing carbon dioxide and the energy-rich gas methane.This master?s thesis has focused on development of the mixture of different organic substances that is treated at a specific plant, namely Mosserud biogas plant.

Tarmflorans påverkan på fetma

Obesity is a problem that increases exponentially in humans and companion animals. It is defined as a big Accumulation of fat in the body and is usually connected with several diseases. This study describes how obesity can be diagnosed, in which way the gut flora can affect obesity, if the gut flora is genetically influenced or not, and how it differs between individuals with obesity and obesity-related diseases. Conclusions of the study are that both the bacterial strains Bacteriodetes and Firmicutes probably have a connection to obesity. The intestinal flora is probably also genetically related.

En tidsseriestudie av varviga sjösediment fra?n Kassjön

This thesis aims to analyse a time series containing the annual Accumulation rate of minerogenic matter in the lake Kassjo?n. First there is a theoretical survey of some frequently used tools for the analysis of time series in the time domain and in the frequency domain. This survey is followed by a simulation study that illustrates how the theoretical tools work in practice. After this, the time series "toolbox" is used to analyse the time series from Kassjo?n (5701 data points).
