Popular Abstract in Swedish Osteoporos (benskörhet) är en sjukdom som drabbar de äldre och leder till att skelettet urkalkas och därmed förlorar delar av sin styrka. Detta bidrager till olika typer av frakturer (brott av benet) där de vanligaste är handleds-, axel-, kot- och höftfrakturer. Andelen frakturer ökar i befolkningen, vilket både medför ökade kostnader för samhället och invaliditet för dThe aim of this thesis was to evaluate bone mass and bone size in girls and boys from age 12 to 16, with special attention to physical activity. We also wanted to retrospectively evaluate the effect of exercise for the years preceding age 12. The findings were as follows. Sixteen year old adolescents in a rural area had higher areal bone mineral density in the total body and the spine compared wit

The moving bed biofilm reactor (MBBR) is a biological wastewater treatment process in which microorganisms grow as biofilms on suspended carriers. Conventionally, MBBRs are mainly designed and optimized based on the carrier surface area, neglecting the dynamic relationship between carrier design, reactor operation and biofilm characteristics, such as biofilm thickness and the composition of the mi

The relationship between glomerular and tubular dysfunction and metabolic control in type 1 diabetes was studied. To that end the urinary excretion rates of albumin and Tamm-Horsfall protein as well as HbA1c levels were measured in 58 patients with different degrees of diabetic nephropathy and in 76 apparently healthy subjects matched for sex and age. The urinary Tamm-Horsfall protein levels were

Baobab är ett träd som främst växer i Afrika, men även förekommer i östra Indien, Sydamerika och Australien. På träden, som kan bli upp till 20 meter höga, växer frukten Baobab. I vardagligt tal brukar frukten benämnas som apbröd, detta eftersom babianerna gärna äter sig mätta på frukten. Det är inte bara babianer som tycker om frukten, utan även människor. Frukten är näringsrik då den innehåller Introduction: In this work, oil from Baobab seeds was extracted and analysed in order to determine how much oil the seeds contain and the fatty acid composition of the seeds. Background: A lot of seeds go to waste when either producing drinks of Baobab fruit or simply eating the fruit raw. Thus, it would be favourable if it was possible to produce a product based on the left-over seeds, suitably

Utrymning i sjukhus ställer speciella krav på brandsystem och byggnader då sjukhus ofta är stora och komplexa byggnader med många människor med olika förutsättningar. Där befinner sig personer i alla åldrar, personer med diverse nedsatt rörlighetsförmåga samt nedsövda personer som behöver assistans av anställda för att kunna utrymma byggnaden. Patienter som behöver assistans vid transport kan ta eEmergency evacuation in hospitals sets special demands on fire protection systems and the construction of the building since hospitals often are large and complex buildings. People and patients of all ages, with reduced mobility, and anesthetized people who are not capable to evacuate without assistance are often present. The procedure of evacuating a hospital is therefore not an easy task. The pu

The conflict mineral crisis has been ongoing in the DRC for nearly two decades, with armed groups and increased military presence have played on the tin, tantalum, tungsten and gold to fund a brutal war across the eastern region of the country. Recent international efforts to tackle such illicit trade in conflict minerals has focused on requiring relevant stakeholders involved in the mineral sourc

Uppsatsen syftar till att undersöka förhållandet mellan arbetsgivares respektive arbetssökandes och arbetstagares rättigheter och skyldigheter i ljuset av de krav på vaccination mot covid-19 som en arbetsgivare kan tänkas vilja uppställa. Genom användandet av den rättsdogmatiska metoden besvarar uppsatsen huruvida en arbetsgivare kan neka en ovaccinerad arbetssökande anställning respektive om en aThe aim of the essay is to examine the relationship between the rights and obligations of employers, employment seekers and employees, in light of an employer’s will to demand that an employee undergo vaccination against Covid-19. Through the use of the legal dogmatic method, the essay examines whether an employer can deny an unvaccinated employment seeker employment and whether an employer can re

Purpose: The purpose of this paper is to explore the phenomenon of unexpected collaborations between brands. Methodology: This paper follows a qualitative research approach. The research is centered around a multi-case study based on secondary data. In the analysis and discussion, the literature review is applied to the case studies to reveal patterns that lead to managerial- and theoretical impl

The demand for space cooling is rising. The increase in cooling demand can put significant strain on the electric grid since approximately 99% of air-conditioning and refrigeration loads worldwide are met with electricity. Many hot weather cities could benefit from district cooling (DC) systems to meet their growing cooling demand in an effective sustainable manner. Since these systems require sig

This study aims to increase the understanding of how an organisation applies crisis communi- cation strategies on social media, how users respond to these crisis communication messages, and what the nature of the interaction between the organisation and users is. Three research questions were developed, which consisted of 1) what crisis communication strategies and tac- tics Boeing uses on Faceboo

A particle accelerator consists of a large number of components, which among other things includes several acceleration modules, which consists of one or several cavities. A cavity is a complex and essential part in the accelerations process and is usually made of oxygen-free copper (OFC) or niobium. These two materials are special when it comes to metal cutting, it´s hard to find information abou

After studying economic integration it doesn’t come as a shock that preferential trade agreements (PTA) have an effect on the countries within the PTA, or outside the PTA for that matter also. The majority of the Latin American countries have been considered as developing countries for the better part of the 21st century, and have, for the most part, been secluded from the world market. Since the

There is no doubt that the construction industry needs to streamline its processes. There are four different ways to streamline the processes; Building Information Modelling (BIM), Lean Construction, industrialized building and partnering. In this examination paper we have investigated the possibility to streamline a specified company’s processes whit lean and BIM. More specific we have investigat

The formation of industry standards for environmental issues and corporate social responsibility is gaining acceptance but the number of successfully implemented programs are few. On an individual level companies have for some time applied company standards or codes of conduct. But on a collective level cooperation seems much more difficult. Although from an economic point of view there are clear

Financial services sector is fundamental to economic growth and development in all advanced economies. Financial services such as banking, savings and investment, insurance, and debt and equity financing constitute a nation's economic engine by fulfilling three core functions in the economy. Firstly, these services provide financial intermediation functions between savers/investors that are lo

Vertical distribution agreements are favourable for the market. They facilitate distribution and make it more efficient. Moreover, by the appointment of independent distributors, it gets easier for the manufacturer to distribute his goods over a wide geographical area and overcome barriers inherent in international trade. However, the co-operation between manufacturer and distributor gives rise to

Bilindustrin är en oligopolmarknad där de tio största tillverkarna står för 80% av världens totala produktion. De stora marknaderna Europa, Japan och Nordamerika har stagnerat och stabiliserats, vilket har förändrat branschen till en med höga fasta kostnader och låga marginaler. Försöket att öka marginalerna och anpassa sig till den japanska teorin “lean production” med kort ledtider i fabriken leThe automotive industry is an oligopoly and the ten largest manufacturers account for close to 80% of the overall global production. The major markets of Europe, Japan and North America, have stagnated and remain stable and this has transformed the industry into a business of high costs and low margins. Somewhat ironically, as an attempt to increase the margins and adapt to the Japanese theory of

Depicting the American system of products liability in general and punitive damages in particular as bizarre is unlikely to offend anybody. People unable to provide their own anecdotal evidence of exactly how twisted the system is are hard to find. Proponents of it, usually lawyers arguing the plaintiffs' cases, are dismissed as biased and profiting from their quarter cuts in billion dollar aw
