Riskerar tatuerare hörselnedsättning i arbetet?

Purpose: To examine the hearing environment for tattoo artists regarding occupational noiseand to see whether tattoo artists are exposed to hazardous noise according to Swedish WorkEnvironment Authority regulations. Method: Using a dosimeter we measured a total ofseven sessions of approximately one hour on seven different subjects, located on five studiosin Gothenburg. As a complement we did also hand out surveys based on twelve questions toexamine habits, experienced sound environment and to see if there were any hearing relatedpatterns. Results:. Sound level measurements showed that the lower Exposure action valueLpAeq,8h 80 dB(A) in one case was reached if applied to the average working time of sixhours.

Neonicotinoids and honeybee health : the effect of the neonicotinoid clothianidin, applied as a seed dressing in Brassica napus, on pathogen and parasite prevalence and quantities in free-foraging adult honeybees (Apis mellifera)

Sub-lethal doses of neonicotinoids have been shown to negatively impact the health of honeybees. However, most studies to date have exposed bees only artificially to these pesticides under laboratory conditions. There have been just a few well designed and replicated studies of the impacts of realistic neonicotinoid Exposure on honeybees foraging under field conditions. In order to close this knowledge gap, and to test the influence of the neonicotinoid clothianidin on honeybees, we used a study system of 16 paired, spatially separated (>4 km) spring oilseed rape fields in the south of Sweden. The fields were paired according to land use, the surrounding landscape and geographical proximity, using GIS.

Operationell risk i banker: Hantering och offentliggörande av operationell risk ? En studie av skandinaviska banker

Starting in January 2007, capital adequacy of internationally active banks will be regulated by the new Basel Capital Accord, International Convergence of Capital Measurement and Capital Standards ? a revised framework, [Basel II]. The framework introduces for the first time minimum capital requirements for operational risk and encourages market discipline of capital adequacy by initiating requirements for public disclosure of quantitative and qualitative information on operational risk Exposure. This thesis examines the nature, definition, management and public disclosure of operational risk in Scandinavian banks based on regulations and recommendations presented in Basel II. We find that the models currently available for addition of operational risk to the capital requirement do not reflect actual operational risk Exposure of banks.

IFRS 9 Fas III: Säkringsredovisning ? Förenkling eller bara förändring?

Den i dagsläget mycket komplicerade IAS 39 som bland annat berör säkringsredovisninghade en del till den stora finanskrisen enligt vissa. Oavsett bakgrund så har utveckling av enny redovisningsstandard för att ersätta och förenkla säkringsredovisning påskyndats. Ettförsta utkast av förslag till förändring för redovisning av säkringar presenterades i december2010. IASB som leder arbetet har redan kritiserats, så hur tar användarna ? företagen emotförändringsförslagen? Genom att ta del av företagens skriftliga åsikter är studiens syfte attundersöka attityderna till förslagen i Exposure draft IFRS 9 Fas III Säkringsredovisning.Detta är en kvalitativ studie där datainsamlingen består av comment letters i vilka företag harskrivit sina kommentarer och uttryckt sina attityder i olika frågor om förändringsförslagenställda i Exposure draft specifikt skrivna angående IFRS 9 Fas III Säkringsredovisning.

137Cesium i myrsamhällen i Gävleborgs län 24 årefter Tjernobylolyckan

24 years have passed since the Chernobyl accident when radionuclides were spread over largeareas of Europe, including the Scandinavian countries. Today, measurable activities of 137Csare still observed in many Swedish ecosystems.Ants (belonging to the order Hymenoptera) are social insects which collect organic materialfrom a large area around their nests. This study focuses on the 137Cs activity in ant nests andthe cesium accumulation in these nests. The aims were (1) to estimate the 137Cs fall-out in1986, (2) estimate the radiation Exposure of ants and (3) find how 137Cs is distributed in an anthill. Seven ant hills (occupied by the species Formica polyctena) were studied near the villageof Hille, situated north of the city of Gävle in central Sweden.

Att välja bok i biblioteksmiljön: En studie av hur bibliotekens exponering av litteratur påverkar biblioteksanvändarnas val

The aim of this bachelor thesis is to describe in part the public library users?process when deciding which books to borrow. Focus is on the library users?experience of the process and how literature Exposure can support them intheir choice of book. This study seeks to find out to what extent choices arespontaneously made at the library, which elements of Exposure that the userfinds helpful in the process and which factors usually influence the user infinding new things to read.The data was gathered through 100 structured interviews with public libraryusers.

Svenska Multinationella verkstadsföretags valutasäkringsmetoder

The purpose of this essay is to investigate how large Swedish corporations within the same industry protect themselves against foreign exchange risks and to determine if there is a general practice for how the protection is done. What is the responsibility structure at these corporations regarding the handling of Exposure to foreign exchange?.

Effekten av Bisfenol A (BPA) på hanråttors (Rattus norvegicus) reproduktion

Today evidence exist that environmental chemicals deteriorate male sperm quality and that testicular cancer is increasing. Bisphenol A (BPA) is a chemical with estrogenic effects used in the manufacture of polycarbonate plastic and are found in, for instance, plastic boxes, feeding bottles and food containers. Much of the research on how men's reproductive ability is influenced are performed on rats. This review article complies how male rat reproduction is affected by BPA as a model for humans. Studies have investigated how sperm are affected, hormonal changes during reproduction and how reactive oxygen species (ROS) affects sperm.

An enriched arena for lamb - anticipation behaviour before entering the arena, effects of skipping the anticipation phase and effects of being denied access to the arena

This study aimed to investigate whether lambs show anticipatory behaviours in a holding pen prior to entering a known arena, whether the holding pen experience prior to the arena Exposure affects their play expression in the arena and whether their behaviour (in home pen) is affected if arena access is denied. Twenty pair-housed male lambs (average 14 weeks old), were exposed, in chronological order, to five treatments. Holding pen treat-ment (HP-control): Each pair was led into a holding pen (2.7 m2) and remained there for 5 minutes before returning to their home pen (6 m2). Holding pen ? arena treatment (HP-A): Each pair was led into a holding pen for 5 min and then was allowed access into the arena (22 m2, containing two hanging chains, one ball and one platform) for 15 min before re-turning to their home pen.

Påverkan av skuggor från vindkraftverk

To get rid of our dependence on fossil fuels we need to make use of renewable energy sources like wind power to a greater extent. Even though wind power is a renewable energy source it can still cause some problems for the close environment. One of the problems is shadow flickering. When the sun is low and the wind blows in a direction so that the rotor blades are positioned at right angles to the sunbeams and ?cut? the sunbeams off.

Framtiden är redan här. En studie om svenska fackförbunds motiv till engagemang i den sektoriella sociala dialogen på EU-nivå.

Swedish trade unions are engaged in several activities at the European level. One of these isthe sectoral social dialogue, an institutionalized part of the European Union. This bachelorthesis examines the motives for Swedish trade unions in three different sectors to engage themselves in the European social dialogue. The three sectors are chosen because of their differences according to their Exposure to competition caused by ongoing globalization and europeanization processes. By interviewing central informants in trade unions which are active in the three dialogues this thesis seeks to learn more about the motives stated by the trade unions.

Naturljud inomhus - En pilotstudie i tre fall

It's an everyday experience shared by many that nature can be of help in relieving pain, reducing stress, support mental recovery etc. In the last three decades or so this experience has also found support in a large number of scientific investigations. Among other things the experience of nature has been shown to reduce stress and pain in patients and to boost concentration and reduce impulsive behavior in children. Most of this research however has mainly been concerned with the visual modality. In this thesis the aim has been to focus on the auditory modality in this context by trying to reveal some effects on people from the Exposure of nature sounds played indoors in three different environments: a grammar school class room, a kindergarten play room and a post-surgery wake up room at an intensive care unit.

Media och dess inverkan : exponering av idealiserade könsroller och dess inverkan på unga människor

The purpose of this study is to examine the impact that idealised body images found in media have on the body-image and wellbeing of young men and women. The study was carried out using questionnaires based on the BAQ and HAD scales to examine the participants' views of themselves as well as symptoms of anxiety and depression. Time spent by the participants using different kinds of media, as well as their degree of social support, was used with the purpose of examining relations and differences in body-image between men and women. The questionnaire contained advertising images to examine whether short time Exposure had any impact on the participants. In order to determine this, one half of the questionnaires contained idealised body-images, whilst the other half contained images without human objects.

Mixture and single-compound toxicity using Daphnia magna : comparisons with estimates of concentration addition and independent action

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.

Hormonstörande ämnen och deras effekt på barns hälsa : - Hur ser kunskapen ut hos småbarnsföräldrar?

Endocrine disruptive chemicals (EDCs) are found in many everyday products and can cause adverse effects on human health. Small children are particularly sensitive to EDCs and they are also exposed to them in a greater extent than adults. Despite this, EDCs are only banned in a few toys and childcare products. There are many sources of Exposure and if no steps are taken to reduce the incidence of EDCs we may face an increasing number of people diagnosed with obesity, diabetes type 2 or various types of cancer.The Swedish Government has set a number of environmental objectives, one of which is calleda non-toxic environment. The Swedish Chemicals Agency was instructed to produce and conduct a national action plan to achieve this goal.
