Benskörhet - Osteoporos är en sjukdom som ökat lavinartat. Idag finns ingen bot, även om forskarna har gjort stora framsteg. En vanlig åsikt är att osteoporos är resultatet av förlorad benmassa, vilket inträffar när människan åldras. Har inte individen nått upp till sin optimala mängd benmassa (peak bone mass) under uppväxten, kan de drabbas av osteoporos utan accelererande benförlust Forskarna menar att den enskilde individen kan till en stor del påverka hur skelettet utformas. Syftet med denna litteraturstudie är att sammanställa riskfaktorer och preventiva åtgärder för barns och ungdomars benhälsa.

Örebro UniversityDepartment of Social SciencesSociology and social psychology, Continuation course, 61-90 p.Essay 15 p, Spring -08.Title: ?Youth (work)seekers?Author: Karolina LindellAbstractThis essay focuses on young people?s social background when they apply for their first job. I have interviewed four young people from a small town in Sweden, to see how social background and identity affects their vital conditions in general. I?m interested understanding the relationship between structure and agency.

Prisons are for many an unknown world, and few know about the prison culture which includes unwritten rules, power structures, interactions and relationships between inmates and correctional employees.While many think that Swedish prisons are too comfortable,inmates are facing extreme stress due to surveillance and detention, by depriving inmates their possibility to shape their own lives. When the inmates is deprived of control over their own life?s the penal system have great power to shape and to influence the inmates.The purpose of this paper is to investigate prisoners' experiences of treatment and exercise of power in prisons. Starting point is to examine what are the kinds of relationships between prison officers and inmates from a power perspective, if there is any difference between the closed and open prisons and how the inmates affected by the structures that exist.Based on my overall purpose, and with my informant´s stories which revealed a number of similar points, four main headings were developed; Mass media and society´s view, and unknown world, interaction between inmates and prison officers and consequences.Prison officers with the role as a contact persons as well and other staff which work close to the inmates play a significant role by supporting through motivational interviewing and can help the inmates to gain insight about their life situation and actions. My informant?s underlined that a good contact person can either help or discourage.Inmates who contributed with their experiences express that there is a big difference between open-and closed prisons.

Due to increasing product availability and higher demands on fast deliveries, the competition between companies is growing. To be able to satisfy the customers? requests an efficient logistics system with short throughput time is required. By using tools associated with Lean production companies are able to make great improvements in their manufacturing systems and reduce lead times to satisfy customer demands.There are two classifications associated with manufacturing, high variety and low volume (HVLV) and low volume and high variety (LVHV). The general belief is that the concept of Lean production is difficult to implement in a production environment with high variety and low volume due to the concept being adapted to mass production.

Syfte: Syftet med uppsatsen var att göra en analys av vilka resultat som deltagarna uppnått efter 2 års dagvårdsbehandling på Överviktsenheten, Karolinska Universitetssjukhuset. Följande frågor står i fokus för denna studie:? Svarar män och kvinnor olika på behandlingen i fråga om relativ och absolut viktminskning?? Finns det skillnader mellan ursprungs-BMI (kg/m2) och viktminskningen, i relativa och absoluta termer?? Skiljer sig olika åldersgrupper åt i fråga om relativ och absolut viktminskning?? Hur ändras sjukdomsprevalensen för IGT/diabetes typ II, höga triglyceridnivåer, hypertoni och metabolt syndrom under behandlingens gång?Metod: Behandlingen innefattar beteendemodifikation i form av förändrade kostvanor och ökad fysisk aktivitet. Uträkningarna baseras på tre mätningar; före behandlingsstart, samt efter 1 och 2 år. Dessa består av blodprover samt längd, vikt och blodtryck.

District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

Carbon sequestration through restoration of degraded pastoral soils is an advocated way of mitigating global warming, and simultaneously alleviating poverty. An often proposed rehabilitation strategy is fencing of pastures, a method that was introduced to the farmers of Chepareria by the Vi-Agroforestry organization in 1987. The landscape of Chepareria changed from eroded, over-grazed grasslands, to a mixture of open-grazed commons, pastoral enclosures and cultivations. The aim of this study was to investigate (1) if the soil organic carbon (SOC) is higher inside the enclosures than on the open-grazed commons, (2) if SOC is affected by duration of fencing and (3) what effect cultivation of pastures has on the SOC. Estimations of vegetation cover and deep profile (100cm) soil sampling was performed on six clusters containing; (1) open-grazing (OG) (2) 1-5 years of fencing (FENCED(1)), (3) 7-10 years of fencing (FENCED(2)), (4) 15-23 years of fencing (FENCED(3)), (5) maize from OG (A(OG)), (6) maize from fenced pasture (A(FENCED)).

Since the 1970s voting behaviour has changed. Party identification and class voting has declined. As the electorate becomes more volatile, campaign strategy and party image becomes essential. Political communication and mass media now play an important role in election campaigns. Therefore, researchers take an interest in the impact of media on public opinion.

As emission legislations across the world continuously pushes engine development forward,engineers constantly need to come up with and implement fuel saving technologies. During thelast decade, variable cam phasing has become a popular solution to increase gas exchangeefficiency. This configuration is typically mechanically constrained by camshaft limitations, anda solution to circumvent this problem would be to use a different valve actuation principle.One example of this is to use pressurized air controlled by electrical solenoids. Such a systemhas been developed byCargine Engineering and this provides the starting point for this work. Tobe able to operate the valvetrain on an actual engine, a control system is needed.

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.

StoraEnso decided in year 2002 to build a pulp mill in the province of Guangxi, southernChina, and also establish eucalyptus plantations to provide it with raw material. By 2010StoraEnso controls about 90 000 of planned 120 000 ha, out of 75 000 ha is already plantedwith Eucalyptus.By using better genetic material, improve the tending, selecting the sites more careful and byusing a proper fertilization regime StoraEnso hopes to increase the mean annual incrementfrom today?s 25 m3/ha, on bark, to 35 m3/ha. This study is one part in this work to increase themean annual increment in the plantation.This master thesis is the forth in a series, that has followed up a fertilization trial that startedin spring 2006 when the trial was laid out and treatments decided. The aim with the trial is toexamine the production potential of Eucalyptus urophylla in Guangxi, southern China.

Bakgrund: I dagens samhälle har varumärken kommit att spela en allt större roll för såväl konsumenter som företag. Varumärken fungerar som en ledsagare i individers sökande efter identitet och samtidigt som en gemensam nämnare eller tillhörighetsfaktor inom olika subkulturer. Företag kan med hjälp av symboliska värden sända ut signaler som stämmer överens med olika individers värderingar och på så sätt attrahera konsumenter och samtidigt ringa in en önskad målgrupp. Dock kan även det motsatta inträffa, det vill säga en annan grupp än den tänkta målgruppen kan komma att adoptera ett företags varumärke och göra detta till en del av gruppens image.Syfte: Syftet med denna studie är att identifiera och åskådliggöra hur en subkultur kan påverka det symboliska värdet av ett varumärke.Genomförande: För att uppnå syftet har det verkliga fenomenet hip-hopkulturens adoption av varumärket Adidas valts att empiriskt undersökas. Detta utifrån kvalitativa intervjuer gjorda med respondenter från hip-hopkulturen så som bland andra gruppen Latin Kings och Infinite Mass, tillsammans med personer från företaget Adidas, samt analyschefen på MTV Nordic Networks och radioproducenten Stefan Wermelin.Resultat: Denna undersökning visar bland annat på att en subkultur kan påverka det symboliska värdet på ett varumärke genom att inte enbart ta till sig de symboliska karaktärer varumärket står för, utan även överföra subkulturens värderingar på varumärkets image.

Within media and communications studies, questions of taste have often been associated with the dichotomy of high versus popular culture. The French sociologist Pierre Bourdieu has also used mass media products in his studies of class determined tastes and dispositions. In this paper the author uses the theoretical framwork of Bourdieu to examine aspects of social class and legitimate taste in the interior design magazine "Sköna Hem", a market leading magazine within it's genre of lifestyle magazines in Sweden. A specific type of feature article, where a real-life home is portrayed, is studied using the critical discourse analysis of Norman Fairclough. The homes portrayed are predominantly affluent and display elements of conspicuous consumtion as mediated through legitimate taste and cultural capital.

År 2008 var 43 miljoner barn under fem år diagnostiserade med fetma. Fetma anses som en kronisk/långvarig sjukdom och ett folkhälsoproblem med behov av förebyggande arbete för att förhindra framtida konsekvenser. För beräkning av kroppsfett används Body Mass index (BMI). BMI är det mått som används världen runt och räknas genom att dividera kroppsvikt i kilogram med längd i meter i kvadrat. Att ungdomarna drabbas av fetma beror främst på dåliga matvanor, obegränsad tillgång till kalorier i form av kolhydrater och fett ofta i kombination med mindre fysisk aktivitet.
