Alléers användning genom tiderna i Sverige : en bakgrund till alléns framtida utveckling

Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.

Konst och kultur : Möjligheter och hinder att använda konst och kultur som rehabiliterande metod inom primärvården

Background:There are future challenges for public health and health care in meeting the needs of a growing and ageing population. Today there are evidence of how arts can contribute to health development and of the connections between arts, health, treating and rehabilitating measures. To be able to meet the future challenges there is a need for new methods, perspectives and views about how to stay healthy, enjoy our existence and for wellbeing. Health care has an important role in rehabilitation through the broad contact with the population. The background of the essay is the pilot project Arts on Prescription that was carried out in order to try a new way of rehabilitation with arts as a factor.

Effekter av kön, ålder och region på sjukpenningen i Sverige - en variansanalys

According to TCO (The Swedish Confederation for Professional Employees) the worst threat to the Swedish welfare is that so many people because of bad health and unemployment are not a part of the labour force. If Sweden could make the number of people with health and unemployment problems half the size as today, the GDP would increase with more than five percent. In real money this means 110 billion Swedish kronor a year. According to SCB (Statistics Sweden) the difference between women?s and men?s absence owing to illness should be investigated more closely in order to get at better understanding of the problem.

BIM - Förvaltarens Framtid

For nearly twenty years people have been talking about Product models, but given that the building industry is so conservative, it is hard to implement new working methods. Product models are these days known as Building Information Modeling, BIM. People often say they work with BIM but they often forget the most important part, the information. A 3D model should be linked with characteristics and information. Information that can be invaluable for the facility manager.We have a vision that in the best of worlds the facility manager would be able to "walk" into the model and see what kind of installations are inside the wall or in the roof.

Genetisk variation av betydelse för mjölkkvalitet i Rödkullerasen :

The Swedish Red Polled breed is threatened by extinction and there are only around 1100 animals left. The breed was popular in the early twentieth century, but since then the numbers have steadily decreased. The overall objective of this study was to find out whether there may be economic incentives for preserving the breed. The milk quality properties are of major importance in the production of dairy products. Therefore we would like to establish if the Swedish Red Polled breed carries favourable alleles at loci of relevance for milk quality, to potentially make the breed more interesting for milk production.

Dynamiska egenskaper hos håldäcksbjälklag belastade med gångtrafik

Concrete floors have traditionally had no problems with annoying vibrations. However with the demand for larger spans the floors need to be made more slender with a higher degree of utilization and lower mass. Therefore new floors may have problems with vibration serviceability. This thesis studies the vibration characteristics of hollow core slabs. The analysis was made in the finite element program Ansys. The hollow core slab was subjected to a varying force simulating one person walking across the slab.

Urban Agriculture i den hållbara staden : en fältstudie i Managua

The way we design our cities today will affect the living conditions for future generations. Planning as a discipline can become crucial to attain a sustainable urban development with an increased quality of life among the urban population and an improved environment. Urban Agriculture in the Sustainable City -a case study in Managua is a Diploma Work that deal with poverty issues, aspects of sustainability and development work. We have had a theoretical starting-point, but our focus has been on the case study i.e. the practical part, that we carried out in Managua, the capital of Nicaragua. Today about half of the worlds 6,3 billion people live in cities. The demographic growth of the countryside has declined, while the population in the cities is considerably increasing.

Utemiljö för motion :

New technology and urban sprawl have resulted in almost half of the population in Sweden being insufficiently physically active. The sedentary lifestyle causes heart- and vascular diseases, diabetes, high blood pressure, cancer, stress etc. in the population. One of the biggest priorities in the society is to promote more physical activity. Through literature studies and a questionnaire this paper will examine how we can design the built environment in order to promote physical exercise and if we can change the sedentary lifestyle with a outdoor environment that invite physical exercise. There are both internal and external factors that have importance for people?s physical activity.

Utvärdering av den svenska cykelhjälmslagen för barn under 15 år : Analys av nationella trender i cykelrelaterade huvudskador mellan 1998-2011

Introduction: In January 2005, a nationwide mandatory bicycle helmet law for children under the age of 15 was introduced in Sweden. In the current study, the effect of this law was evaluated by analyzing national trends in hospital admissions due to bicycle-related head injuries during the period 1998-2011.Methods: An interrupted time-series design with segmented regression analysis was used to evaluate the intervention effect on head injuries as a percentage of all injuries (%HI) among cyclists in age- and sex-specific groups. Effect was measured as a change in level and/or slope of the trend at the time of legislation.Results: A total of 35261 cyclists (0-54 years) were hospitalized due to a bicycle injury during the study period. Linear regression analyses of the entire study period (not segmented) showed significant year-to-year decreases in the %HI of 1.3-1.7% in all age and sex-specific groups (p < .0001). Results from the segmented regression analysis showed that, at the time of legislation, a significant drop in level occurred among males under 15 years (-4.5% [95% CI: -7.7% to -1.3%], p = .01) and a significant change in slope occurred among females aged 30-54 years (-1.6% [95% CI: -2.9% to -0.2%], p = .025).Conclusions: The law seems to have had an effect on males in the target population (<15 years).

Jämförelse mellan en fängelse- och en icke brottsdömd population av deras samvetsgrannhet och psykopati : en tvärsnittsstudie av skillnader och deras möjliga betydelse

Tidigare forskning (t.ex. Miller & Lynam, 2001) har påvisat att intagna i fängelse harlägre nivåer i personlighetsegenskapen samvetsgrannhet än ostraffade individer. Enstudie i Sverige (Eriksson, 2010) har funnit motsatsen. Det råder viss oenighet inomvetenskapen om sambanden mellan samvetsgrannhet och psykopati hos kriminella. Syftetmed föreliggande studie var att undersöka skillnaderna mellan straffade och ostraffadeindivider samt utreda motstridigheterna i litteraturen.

Ledningsarbetet hos ett krisföretag : en analys av ledningens hantering av en ekonomisk kris

Almost every company sooner or later ends up in a more or less difficult economical situation. The reason for the economical crisis varies for each individual case but common for them all is that it is the management group that has failed in their work to guide the organisation to avoid a negative result. The next common denominator is that it is the management group that has to handle the changes in the company's environment and lead the company out of the crisis. But how can they do this and take decisions in a rational and effective way and is there warnings signals that the management group missed before the crisis was a fact? This is some of the questions that this study is going to discuss and analyze. The aim of the study is from a management perspective chart the strategic work of the company's management work when handling an economical crisis.

Smart konsumtion : unga vuxnas attityd till miljö- och rättvisemärkta produkter

We are more aware than ever about our impact on the common environment and the world's population. Consumption awareness can be one way to take social and environmental responsibility. This study aims to examine young adults' (19-30 years) attitudes toward consumption awareness in Sweden. Consumption awareness is treated in this study as the consumption of environmental and fair-trade labeled products that have been certified of a third party. The study is limited to everyday commodities, which in this case is groceries, household consumables and clothing.

?r omfattande varum?rkesr?ttigheter nyckeln till innovation? En utredning av risker vid individanpassning av kl?der p? den europeiska marknaden

This thesis examines the legal boundaries of third-party use of trademarks in the European customized clothing market. The purpose is to determine under what circumstances third parties may legally modify and sell trademarked apparel without infringing on trademark rights. The study employs a legal dogmatic method, analyzing EU trademark law, case law, and legal doctrine to clarify the scope of exclusive rights and their limitations. By analyzing key EU case law, the study further illustrates how the legal framework has been interpreted and applied in cases concerning third-party trademark use. Given the increasing demand for customized fashion and the rise of new business models in the clothing industry, this topic holds significant legal and economic relevance. Additionally, Schumpeter?s theory of creative destruction provides a theoretical perspective on how trademark restrictions impact innovation and market competition.

Crowdsourcing : Vad motiverar studenter till att delta?

AbstractTitle: Crowdsourcing ? What motivates students to participate? Level: Bachelor thesis, 15 credits. Authors: Sara O?ra?s & Tomas PetterssonSupervisor: Martin AmsteusDate: June 2013 Introduction: More and more companies realize the importance of using external resources to generate the best possible developmental outcomes for their particular business. The probability that all the smart people work for your company is not very big, therefore it is wise to use the public and take advantage knowledge, ideas and expertise of the public. Crowdsourcing is when a group of people is challenged to solve a problem for a company or to generate solutions and innovative ideas in exchange for compensation. A key issue is the question of what motivates individuals to participate in crowdsourcing.

Gångtrafik i citymiljöer : En studie via två angreppssätt

It is a well known archaeological concern that the remains of human bones left from the bronze age and early iron age Scandinavia are not nearly enough to represent the estimated population of the time. Furthermore the bones of each find rarely represent a whole individual. The majority of the bones must have been disposed of somewhere else, possibly scattered in running waters or in the fields, where they have evaporated or are securely hidden from archaeological excavations.This thesis deals with the grave concept and the problem in using a word that is so very clouded by its modern, western meaning. It also offers an alternative explanation to why the bones are handled the way they are and why they are found in such awkward contexts..
