In this literature review the characteristics of two free-floating macrophytes, water hyacinth   (Eichhornia crassipes) and duckweed (Lemna sp.), and two microalgae, Chlorella and Scenedesmus, have been examined regarding their suitability as efficient nutrient removers in the treatment of wastewater with high levels of nutrients and suspended solids from a biogas plant in Loudden. The needs required for the plants to be able to grow in wastewater and the amounts of biomass they can produce have also been studied. The results show that Chlorella is capable of a very high uptake of nutrients in photobioreactors with high nutrient loadings. With an ammonia uptake maximum value at 10900mg/m2/d Chlorella outshines the other organisms in this study. The test organism that performed the closest to Chlorella in terms of nitrogen uptake was water hyacinth with an uptake about 1602mg/m2/d.

The aim of this paper is to see if Sweden has implemented the recommendations and taken notice of the guidelines for employment that the Commission and Council set up every year and from this see the role of the Commission and Council for the national employment politics. The years that I focused on in the paper are year 2000- 2004. The method that is used is a case study research that is exploratory and explanatory. The theoretical starting points are theories about delegation, cooperation and a variation of control and autonomy. This is recognized in the Principal- Agent theory and the Principal- Supervisor-Agent model.

One part of preventive conservation is controlling the lighting in the exhibitions. As a first step we have to accept the fact that the very act of displaying objects is causing them damage, and because the trend is for everything to be open to the public view all the time, the aim is to minimize light exposure of exhibits.This essay will present lighting options and relate them to the current recommendations. I have put the emphasis upon describing which methods one can use to minimize the degradation of exhibits on display by eliminating UV- and IR-radiation and reducing the visible light. The intention with this essay is to investigate the current lighting options and compare these to the recommendations on lighting exhibitions.The selections of different lighting options such as LED-, halogen- and energysaving lamps were made based on avaibility. Thereafter I did two types of investigations.

In  the  constantly  changing working  life  of  today, where  emphasis  on  human  capital  grows stronger,  the  importance  of  recruiting  and  retaining  good  staff  increases.  Successful recruitment  requires  a  first-rate  recruitment  process.  In  literature  on  recruitment recommendations for successful recruitment are presented.   The  aim  of  this  study  is  to  describe  similarities  and  differences  between  these recommendations and Svenska Spel?s recruitment practice on the basis of a description of the recruitment process at AB Svenska Spel, and also to identify possible reasons for differences between theory and practice.  To  meet  the  purpose  of  this  study  literature  and  scientific  reports  have  been  studied. Interviews  with  five  HR-specialists  and  four  managers  have  also  been  conducted.  The recruitment process is therefore described out of the employer?s point of view.

Better, more efficient fertilizers with great productivity and economic returns are needed, but it is important today to find fertilizers that are also sustainable. It is also important to carefully monitor their impact on the environment, including potential side-effects. In this context, the microbial communities that carry out numerous essential functions contributing to a functional ecosystem are of particular interest. The present study is a complement to a pot experiment that investigated the potential of different waste products for use as fertilizers and how they affect the microbial community. In the pot experiment, the clearest treatment change in microorganism community function was found in the fully fertilized treatment used as a positive control. The question was whether this was indirect, i.e.

This report is commissioned by the Water and Sewage Agency in The City of Mariehamn, Åland. The basic aim is to investigate positive or negative effects of a relocation of the sewage pipe from a wastewater treatment plant, Lotsbroverket. The environmental licence of Lotsbroverket is to be revised and The Environmental Appeal Board at Åland?s Government and Administrative Board has made demands that several possible locations in an outer water area should be examined. The present location of the sewage pipe is in Svibyviken, which has been classified as an ?inner water area?.The objective of this work is to study to which extent the nutrient loading from Lotsbroverket influence the environmental conditions in Svibyviken, and to investigate the suitability of different locations of the wastewater pipe from Lotsbroverket.The way a coastal area looks, i.e., its morphometry, determines to a large extent its ecological characteristics.

In the process of making carton boards into Skoghall Mill, are great quantities of water being contaminated. This water has to be treated before it is possible to release into the recipient, Kattfjorden. One of the contaminations that is important to extract from the wastewater, is organic carbon (measured as TOC-total organic carbon) because microbiological breakdown can lead to the bottom becomig free of oxygen.The wastewater treatment at Skoghall Mill is done through an external wastewater treatment that is located at the factory. The biological treatment (aerated lagoon) is a 140 000 m3 water pool with surface aerator, which is give oxygen to the water. In the lagoon live microorganisms who performs the biggest part of the TOC-reduction.One problem with the lagoon is that the treatment of TOC is considerably worse during wintertime than during summertime.

Title: The auditor?s recommendations to small businesses in the choice of K2 and K3Authors: Christopher Dimovski and Dennis Carlsson Published: Spring 2014 Background: The background of this study is the introduction of the new K-regulations. For small businesses, there is a possibility to choose between the rule-based K2 and the principal-based K3. It becomes mandatory to apply the K-regulations from 2014. We want with this study understand and explain the significance of the auditor and its recommendations to small businesses in the choice between K2 and K3. Aim: The aim of this study is to describe how the auditor makes recommendations to small businesses in the choice between K2 and K3 and through that create an understanding of what influence the auditor have when it makes recommendations and at the end contribute to the building of models. Formulation of problem: How can we understand and explain the auditor?s recommendations to small businesses in the choice of K2 and K3?Methodology: We have used a qualitative method where we have interview eight auditors.

The EU Water Framework Directive has led that management follows the boundaries of natural catchments.The Swedish waters suffer from a nutrient overload that originates mainly from diffuse sources such as agriculture and the subcatchment of Hackstabäcken in Vallentuna Kommun, just north of Stockholm, has been chosen for this study because of its high nutrient load and because it has undergone obvious changes in land use through the years.In this study, the land use in 1902 is compared with the land use in 2011 in order to investigate if it has influenced the ability of the landscape to produce ecosystem services related to nutrient removal. These services will continue to be produced as long as the system is stable and resilient, but when landuse changes and manure from horses increases it will lead to disturbances that can convert a system from one regime in to a completely different one. That will result in loss, or degradation, of ecosystem services such as denitrification, phosphor sedimentation and adsorption, vegetation uptake and infiltration.The results of this study are based upon area calculations of landuse from old maps from 1902 and 2011. Through these maps it becomes clear that the forests in Hackstabäcken, has increased with 170 ha together with an urbanization of 311 ha, at the same time as wetlands and arable land has diminished and lakes has suffered from reductions. Wetlands have been reduced with 76 ha and the ones remaining are of insufficient quality from a nutrient removal perspective.Data from 1902 and 2011 regarding number of horses and bovines indicated a decrease in bovines and an increase in horses.

Previous research has shown that the market reacts on stock recommendations. As the Internet has made financial information more available and cheaper to assess one could believe that the market reflects more available information today. If this is true the market will react less on recommendation made by journalists, which generally consists of processed public information. The stock market should thus be more efficient according to the efficient market hypothesis. This study examines initially if we can conclude that stock recommendations made by journalists generate returns above the expected returns, hence abnormal returns.

The study was a quantitative cross-sectional study which aimed at investigating college students? eating habits in relation to the Swedish food agency dietary recommendations. The likely factors associated with eating habits and attitudes towards dietary recommendations were also investigated. Non probability sampling method was used giving rise to convinient study sample of 51 individuals (41 women and 11 men) ages 19 to 37. The participants were part of four different types of educations, Care and health, Economy, Engineering, computering and societal planning and Culture and media.

Horses are grazers with a digestive system that is adapted for a high fiber diet. Forage is a fiber rich feed that includes grass and legumes. A deficiency of forage and an excess of grains may cause gut disturbances and stereotypic behavior. The aim of this literature study was to summarize information on the horse?s capacity to consume forage-only diets with focus on the horse?s need of energy and protein.

Construction of wetlands in the agricultural landscape may reduce nitrogen and phosphorus transfer to streams, thereby reducing the eutrophication of lakes and seas. The agriculturalstream Lillån, a tributary to stream Sagån, ends up in Lake Mälaren and is transporting large amounts of these plant nutrients. The aim of this study was to estimate how hypothetical wetlands of different size and location may reduce nitrogen and phosphorus load from stream Lillån. Estimated nutrient retention in several small wetlands was compared to retention in a single large wetland based on existing data from the agricultural stream and from a nearby smaller stream. Retention in the stream was suggested to decrease along with the nutrient concentration in the water.

It is important to construct or recreate different types of wetlands and study their retention of nutrients, since knowledge of their effectiveness in this matter is poor. In 2003 a wetland was constructed on an old meadow on the western shore of Lake Bornsjön in central Sweden. The main purpose of the wetland was to reduce the amount of phosphorus entering the lake, which is the back-up water supply for Stockholm when the city cannot obtain water from Lake Mälaren. Large areas around Lake Bornsjön consist of agricultural land and the nutrient concentrations in the inflows to the lake are usually relatively high (approx. 1 mg/l total nitrogen and 0.05-0.1 mg/l total phosphorus).
