Eutrophication is an environmental problem that affects more than ten percent of Swedish lakes. Excess nutrients increase the growth of algae, and cause major problems in the ecosystem through oxygen-free bottoms, fish kills, and at worst dead bottoms. Agriculture accounts for 44% of human emissions of phosphorus to lakes and rivers. Leaching occurs of particle bound phosphorus and of dissolved phosphate. The amount of phosphate in the soil solution that may be leached is partly due to the prevailing pH in the soil solution. The purpose of this study was to investigate how the relationship between phosphate solubility and pH was affected by liming.

 This paper evaluates the effect of exchange rate risk on the sum of bilateral trade. To distinguish the effect between different types of countries, two groups are defined: advanced and developing economies. Economic theory on exchange rate risk and trade proposes ambiguous effects of increased volatility. However, the ex ante hypothesis is that developing economies are more sensitive to volatility. Contrarily to the hypothesis, the empirical results suggest that advanced economies would benefit up to twice as much from a removal of exchange rate risk.

Background: Energy drinks have been found in everyday-stores since 1997 and their popularity have increased over time. Consumtion of energy drinks takes place because of their ability to increase concentration and to decrease fatigue but also because of the popularity the drinks have got. Target groups for these stimulating beverages are adolescents and young adults. Energy drinks contain caffeine, taurine, glucuronolacton, carbohydrates and B-vitamins and voices have been raised about the eligibility for young people to ingest large quantities of these kinds of substances. Because of the properties of these substances it has become popular to mix energy drinks and alcoholic beverages to make up for the negative effects of alcohol and to be able to drink larger quantaties.Aim: The aim of this literature work was to investigate cognitive effects of the combination of caffeine in terms of energy drinks and alcohol and to determine if these effects could be harmful.Method: This literature work is based on five scientific articles retrieved from PubMed.

The United States use of Unmanned Combat Aerial Vehicles (UCAV) or drones for targeted killings of terrorists has been on the rise in recent years and the method has become the core element of president Obamas strategy in the war against terror. This study examines the deterrent effect of targeted killings on terrorism using UCAV/drones as a method of counterterrorism. Building on the literature on counterterrorism, UCAV, targeted killings, deterrence theory and statistics on terrorism the study provides a case study of the CIA drone operations in Pakistan between the years 2004-2010. The goal has been to analyze drone operations and the extent of terrorism from the beginning of the drone campaign until 2010. This as a means of identifying possible trends in terrorism activity due to the occurrence of drone strikes.

Semi-natural grasslands have a high biodiversity and host ecologically and economically valuable ecosystems and species. Restoration on these types of land is often done by removing trees and scrubs, mowing, grazing, changing the soil by removing nutrition or changing the structure of the ground. Another way of restoration is planting seeds of common grassland plants. By comparing 18 scientific publications I investigated if the restoration was affecting the plants in a positive way and if the effect was similar for insects. By comparing the publications, time seemed to have an important effect on insects. They needed time to recolonize restored areas.

De senaste åren har det skett en nedprioritering av risk- och krisföreberedande arbete på kommunal nivå, främst gällande naturkatastrofer. En av anledningarna till detta är att de kommunala medlen prioriteras mot andra saker som exempelvis skola, vård och omsorg.Syftet med uppsatsen är att undersöka lärdomar och förmåga rörande hanteringen av naturkatastrofer på olika myndighetsnivåer i Sverige. Lärdomar studeras utifrån ett verkligt exempel: skogsbranden i Västmanland sommaren 2014. Huvudfokus för uppsatsen är att studera Uppsala kommuns förmåga att hantera en eventuell framtida naturkatastrof.För att undersöka syftet används två teoretiska modeller: Framgångsfaktorer för krishantering samt DROP-modellen. Framgångsfaktorerna används sedan för att se om lärdomar har inhämtats ur skogsbrandskatastrofen.

Municipalities with a higher amount of female representatives has been shown to be more gender equal. Earlier reasearch has also shown that female politicians are more likely than male politicans to represent immigrants and refugees interests. However, the effect of female representation has not been tested on other subordinated groups than women. Swedish municipalities have full autonomy regarding refugee reception and local politicians are responsible for the decision on the amount of refugees that the municipality accept. The variations of female and male politicians in the local assemblies are expected to have different outcomes on the refugee reception, according to females social backgrounds and experiences.

AbstractPurpose/Aim: The purpose of this paper was to identify the communication process at the company Cherry casino and see what opinions the employees had about it. Moreover, an evaluation of the used strategies was done and an analysis about what perhaps could be done to improve the attitude, communication and in the end the result for the company.Material/Method: The empirical material was gathered through qualitative interviews and theory application.Main results: The transmission of information regarding the regular work related information works just fine and the channels used are well chosen. But more large-scale information that deals with the company?s plans, strategies and targets is not handled in the right way. Neither is the respond.

The aim of the study is to investigate how a teacher and a special education teacher cooperate to prevent a pupil with reading difficulties from ending up in the vicious circle of the Matthew effect, and to find out how a pupil with reading difficulties experiences his or her reading situation. This case study is based on a phenomenological perspective whereby qualitative interviews illuminate a commonly occurring problem in today?s schools. Interviews were conducted with a teacher, a special education teacher, and a pupil in grade 1, in order to cover everyone?s perspective in this situation.

This paper describes a method for wireless energy transfer via near-field electromagnetic inductionthat is inexpensive, simple and can be applied to almost any type of system, regardless of size andenergy demands.The method uses a primary unit consisting of an oscillator, amplifier and inductive coil thattransfers energy to a secondary unit consisting of a coil, rectifier and voltage regulator. Two typesof oscillators and several amplifier designs were realized and evaluated together with a multitudeof flat coils of both monofilar and bifilar type.The results show that it is important to use an oscillator whose frequency is dependent on theinductance of the connected transmission coil, such as the Colpitts oscillator. This is preferable toan oscillator with a preset frequency, such as a Schmitt-trigger oscillator..

This study investigated the effect different contexts have on personality items when they are framed more neutrally. The study was based on a five-factor personality inventory originating from International Personality Item Pool. The inventory consisted of 50 original and 50 neutral personality items and in addition 28 items measuring social desirability. The sample consisted of 150 students from the Department of Psychology, Lund. The students were divided into three instruction groups differing in context.

För att minska energiförbrukningen i Sverige krävs att befintliga byggnaderen ergieffektiviseras. Det finns även befintliga lokaler i landet som är i behov av en sänkt energiförbrukning. Det sker ständigt initiativ kring arbete med energieffektivisering av framför allt bostadshus. När energiförbrukning ska sänkas i industrilokaler läggs fokus på att minska energiåtgången i de invändigaprocesserna men inte i det omgivande klimatskalet där transmissionen utgör en stor del av energiläckaget. Syftet med arbetet är att öka kunskapen om energieffektiva åtgärder vid renovering av klimatskal hos industrilokaler.

This study focuses on work related factors which have an effect on the balance between peoples work and private/social life. Commonly discussed in the daily debate is the so called ?livspusslet?, the time puzzle. The question is: How do you balance the demands from work, family and society? A lot of peoples health and family relations suffers from a stressful situation at work.It?s not hard to figure out that the possible factors which could have an effect on the balance between peoples work and private/social life are many.

In the dog breed Nova Scotia Duck Tolling Retriever (NSDTR) several dogs suffer from joint pain and possibly pain from the muscles. This diffuse disease is called Immune-mediated Non- Erosive Arthritis in Nova Scotia Duck Tolling Retriever. The disease is most likely of autoimmune nature where the etiology still is unknown. The musculoskeletal symptoms of stiffness and shifting lameness are intermittently seen. Some dogs also have dermatological changes and some dogs suffer from pain when opening their mouth. The study included 20 diseased and 20 healthy NSDTR. The purpose was to describe immune-mediated arthritis in NSDTR based on symptoms, results of analysis and effect of treatment. Among the diseased dogs 65% had serum positive for antinuclear antibodies by indirect immunofluorescense (IIF) ANA-test.

The purpose of this study is to examine in what way a strong corporate culture can have an effect on the ways that individuals perceive their own identity based on different social aspects, thereby meaning the influence of personalities in relation to the environment. In this essay I have used the theory of employer branding in an analysis of the corporate culture at Ikea Barkarby, with the purpose to answer the following questions: How does the relation between the employee and the corporate culture appear from an identity perspective, i.e can an individual?s identity be affected by the influence of a strong corporate culture? If the corporate culture has an influence on the individual?s identity, what rhetorical tools are part of this? How can the surrounding corporate cultures possibly influence the employee?s process of becoming a part of the corporate culture? The method of research that was used in this study is a framing analysis and a semistructured interview method. In the discussion of the influence of social environment on identity I have used the rhetorical term doxa. The material that was examined was an advertisement for employment from the Ikea Barkarby website as well as the response from my interviews of some of the employees.The result of the analysis shows that it is possible for an individual to negotiate with himself about his identity in relation to the actual situation and environment, meaning a possible transformation of the individual?s behavior in different social contexts, in this example the corporate culture at work.
