Soil carbon in small-holder plantain farms, Uganda : a comparison between agroforestry and non-agroforestry

Smallholder farmers in Uganda suffer from declining productivity. With a rapidly increasing population, marginal land is taken into production and the current land management leads to loss in soil fertility and escalation in soil erosion. There are studies indicating that the use of agroforestry increases soil organic carbon (SOC) compared to systems without trees. Soils which are high in carbon have many advantages, for example better water holding capacity, which can reduce stress on crops during drought. The aim of this study was to determine the effect agroforestry has on SOC concentration in small-holder farming systems in Uganda. The intended system to study was farms practicing agroforestry methods or not in intercropped plantain (cooking banana) fields.

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.

Motorikens betydelse för inlärning

AbstractMy purpose with this study is to find out if it helps children who have diffuculties with their concentration if they get to practise their motor behaviour knowledge during their day at the school to promote their learning capacity. My purpose is also to find out how schools works with motor behaviour training. To get answers to my questions have I done interviews with four educationalists and I have also used books and internet sites. Motor behaviour is of importance to how children learn things in the school, without a well working motor children gets difficulties to sit still and to concentrate. The children may put their energy at the wrong things in the classroom, when the energy instead should be need to learning things.

Växters förmåga att ackumulera metaller : Vass, bredkaveldun och gäddnate i Bergviks dagvattendamm

AbstractSurface-water includes different kinds of pollutants from traffic and roads. To prevent these pollutants to reach nearby lakes one can construct surface-water ponds on locations with heavy traffic. At Bergviks shopping centre in Karlstad, two ponds, one smaller and one bigger has been constructed in order to decrease the pollutant pressure from the receiving waters of Kattfjorden. Several heavy metals are essential for plants and animals in low concentration but when they occur in higher concentrations, they become toxic to the organism. The larger pond at Bergviks shopping centre has a sedimentation function so the heavy metals sink to the bottom thereby not releasing directly in to Kattfjorden.

Prevention av främre korsbandsskador inom idrott: En litteraturstudie

Risken för att drabbas av en ACL-skada är relativt låg men med idrottande ökar risken avsevärt. Störst risk att drabbas har unga aktiva kvinnor. Prevention av knäskador är viktigt för att kunna förhindra sekundära påföljder såsom knäartros, knäinstabilitet, smärta och nedsatt rörlighet. Risken för artros är 105 gånger större i ett korsbandsskadat knä jämfört med ett oskadat. Syftet med den här studien var att sammanställa den vetenskapliga litteraturen över åtgärder för att minska incidensen av ACL-skador inom idrotten.

Hemlösas situation i Kalmar : Exkludering ur ett genusperspektiv

Title:?Speed cameras - an prevention of crime and a standard forming instrument of control??Authors: Markus HanssonTutors: Bo Isenberg & Carl HultExaminator: Ulf DruggeThe School of Human SciencesUniversity of KalmarThe studys purpose is to get a absorbed understanding for peoples attitude, and effect of speed cameras. The disposition for the study is to integrate earlier studies in the matter, combined with elevating interesting sociological conceptions. As an attempt to understand speed cameras as an instrument of force on the individual have Michel Foucaults concept Panopticon been used to see its effect, and it?s look upon how crime prevention will be formulated, which can give an explanation of why speed cameras are being used as an instrument of control on the traffic area.

Hiv i Sverige - Prevention, sexuella attityder & beteenden

ABSTRACT. Introduction: Human Immunodeficiency Virus (HIV) is a retrovirus which occurs worldwide and spreads between humans mainly through sex, from mother to child, blood and blood products and between injecting drug users. After been infected with HIV for a couple of years the final stage of the infection progress into Acquired Immune Deficiency Syndrome (AIDS), and there is no cure or vaccine, only medication that delays the development of the disease. Objective: The aim of this thesis is to examine the preventive work against HIV in Sweden, the groups at risk for getting infected and to highlight sexual attitudes and behaviours among adolescents and young adults. Method: A literature based study method was used and the material is based on scientific articles and reports from active actors within the field of HIV prevention.

Alkohol och arbetslivet : En studie av alkoholkulturen i en svensk arbetsorganisation och dess inverkan på de anställdas inställning till alkohol.

Since drinking habits are created in social environments the workplace has an important role in alcohol prevention. This study has investigated employees (N=216) in a Swedish municipality work organisation with the purpose to describe the alcohol culture in workplace and how it influences on the workers attitudes towards alcohol. The theoretical baseline for the study has been Ames and Janes framework that explains the relation between workplace culture and drinking habits among workers. The study showed significant relations between restrictive attitude towards alcohol and not drinking with co-workers (POR: 2.5) and feeling low pressure in the work situation (POR: 2.2). Therefore it should be of interest for employers to adopt a cultural perspective and a primary prevention strategy in their alcohol policies that focuses on social relations and the workplace conditions.

Mobbning : Fyra pedagogers förebyggande arbete mot mobbning

Bullying is a big problem in schools and many children are afraid of go to school. There are many methods and measures to prevent bullying, but bullying is still remains. This study is about the differences and similarities between methods to prevent bullying at two classes. The purpose of my essay is to research measure that uses by four teachers to prevent bullying and to get description of their work against bullying.My question is: How is the prevention of bullying in the two classes where informants working?This study is focuses on prevent bullying at two classes on two multicultural schools in Stockholm.

Bedömd eller dömd

Trycksår medför lidande för patienten, förlängd vårdtid och ökade ekonomiska kostnader för samhället. Ett första led i prevention och behandling av trycksår är riskidentifiering och bedömning av nyinskrivna patienter, patienter vars tillstånd har förändrats under vårdtiden samt patienter som skrivs ut från sjukhuset. Syftet med denna studie har varit att undersöka följsamheten avseende användande av modifierad Nortonskala för riskbedömning av trycksår på UMAS. Statistik från tre kliniker på UMAS har sammanställts och granskats. Resultatet visar att patienter i hög grad inte riskbedöms vid in- och utskrivning.

Avena Sativa - En hyperackumulator? : En studie av havres kadmiumupptag

The aim of our research was to investigate if oat is capable of extracting cadmium to such extent that it is usable in decontaminating polluted soils. We grew oat in a hydroponic culture during 28 days in a controlled environment and a total of 30 plants were used. The nutrient solutions were contaminated with cadmium of ten different concentrations after seven days. After harvesting the plants, the roots were separated from the shoots, placed in separate containers and then turned to ashes. The cadmium content was measured three times per sample in an atomic absorption spectrometer.Our results indicate that the ability of oat to extract cadmium from a solution is linearly dependent of the cadmium concentration of the solution.

Jämförelse mellan MultiScat och konventionell beräkning av intensiteter till koncentrationer vid analys med röntgenflourescensspektrometri

In this master thesis work, a new method called MultiScat, is compared with the conventional method with alfa-correction, for computing concentrations from intensities in X-ray spectrometric analysis. The conventional model is a linear model, which only takes the photoelectric effect into consideration. It doesn't consider Rayleigh and Compton scattering even though it has a great impact on the measured intensities. Here MultiScat differs a lot. MultiScat is based on a solution of the Boltzmann transport equation.

Breed differences in natriuretic peptides in healthy dogs

Measurement of plasma concentrations of natriuretic peptides have been suggested to be of diagnostic and prognostic value in canine cardiac disease. In several previous canine studies, however, a considerable overlap between investigated groups has been identified. A reliable natriuretic peptide test for use in clinical practice requires establishment of reference values for natriuretic peptides in healthy dogs and cut-off values for subclinical disease as well as for clinical signs of congestive heart failure. Numerous physiological, pathological and pharmacological factors, aside heart function, may influence concentration of natriuretic peptides. A potential effect of dog breed on natriuretic peptide concentration has been suggested but has, to our knowledge, not previously been specifically studied.

Det är patienten som behandlas inte symtomet: Distriktssköterskans erfarenheter av det preventiva arbetet med patienter som har hypertoni

Ett blodtryck som överstiger 140/85 mmHg diagnostiseras som hypertoni, och upptäcks ofta av läkare och distriktssköterskor i primärvården. Forskare menar att hypertoni går att förebygga med prevention, och att förebyggande åtgärder är ekonomiskt försvarbart då många drabbade är i arbetsför ålder. Prevention av hypertoni innefattar förändring av patientens levnadsvanor och kan implementeras av distriktssköterskan. En kvalitativ studie genomfördes av författaren under hösten 2011. Sex stycken distriktssköterskor från fyra olika vårdcentraler intervjuades om sina erfarenheter av prevention för patienter med hypertoni.
