Skydd mot yterosion i slänter av finmorän

Slopes in fine till soils are exposed to surface erosion due to rainfall, snowmelt and upland water sources. Large areas of road slopes are therefore covered for surface erosion protection. Preventive methods like ditches and trenches are also being used. Silt tills are particularly troublesome since the water can bring the soil into suspension and cause mudslides. Different methods for erosion protection have been studied in this work, with the emphasis placed on rockfill covering. The need for and the dimensioning of this type of covering has been examined in literature and field studies.

Kulturarvets skydd i väpnade konflikter. Kulturarvsbrott vid ICTY

This graduation thesis aims to give a survey of how cultural property is protected withininternational law and how these protections worked during the conflicts in the formerYugoslavia and later at the International Tribunal for the former Yugoslavia, ICTY.Cultural heritage is important symbols for ethnicity, religion or political views. Because ofthis cultural property has been targeted in armed conflicts as long as can beremembered. The protection of cultural property within international law has developedfrom the midst of the 19th century up til today and is still developing towards strongerprotection. One of the latest armed conflicts where the cultural property became targetedwas the wars in Yugoslavia in the 1990?s.

Ombyggnation och modernisering av transformatorstation för anslutning av vindkraft

Detta examensarbete är utfört på uppdrag av Rejlers Ingenjörer i Göteborg. Syftet med arbetet är att genom en projektering övergripande presentera utförandet, komponenter, funktioner, ekonomi och situationsplaner för två förslag på stationsutformningar i samband med en ombyggnation och utvidgning av en transformatorstation. Transformatorstationen har i nuläget två spänningsnivåer på 40 kV och 10 kV. I samband med ombyggnationen skall stationen kompletteras med ytterligare en spänningsnivå på 20 kV, för anslutning av ett antal vindkraftverk. För att anläggningen skall uppfylla grundläggande krav, utförs projekteringen genom att sortera och sammanställa relevant information från gällande föreskrifter, standarder och tekniska riktlinjer.

Att både stötta och skydda : en diskursanalys av barnavårdens arbete med hedersrelaterat våld

The purpose of this essay has been to study the different discourses that are expressed in social welfare secretaries? assertions when they assess cases with elements of honour-related violence, intimidation and oppression. To do so I have used a discourse analysis theory and technique, based on three qualitative interviews with social welfare secretaries. The interviews were focused on vignettes, which were all fictitious cases with various elements of honour-related violence. One of the interviews was a focus groupinterview with four participants, while the other two interviews were individual.

"The love that dare not speak its name" : om sexuell läggning och flyktingskap

The purpose of this composition was to examine which international and Swedish laws exist to govern the protection of asylum seekers claiming persecution on the grounds of sexual orientation. Additionally I wanted to look at what the need for such a right to refuge would be based upon, i.e. why asylum seekers ought to be granted such protection. In order to fulfil my objectives I based my material on international and Swedish laws, comparing these to studies of what negative impact growing up and living as homosexual in an oppressed environment can have on the individual, psychologically and socially. To highlight and exemplify my material I used Iran as a case-study to reflect my facts upon.I found that there has been, and still seems to be a lack of interest in and commitment to the persecution of homosexuals around the world.

Datasäkerhet : Hur man skyddar sig mot interna hot

As the companies of today are good at protecting themselves against external threats, but are having problems with internal threats, we focused on how information can be protected from ending up in the wrong hands. First and foremost to protect information from employees who might steal it and sell it to another company. Since the security investments needed are connected to the financial costs of implementing them we have tried to create a balance between the investments needed and the cost of implementing them. The different kinds of protection needed are first and foremost protection to make data less accessable, passwords and traceability. While it is hard for us to estimate the amount of money a company lose by the hour when the production stands still, we have not been able to use any of the excising models to calculate the profit of installing countermeasures.

Skydd på vilken grund? En komparativ fallstudie av den svenska utlänningslagen.

This paper studies the Swedish Alien?s Act regulations regarding individuals in need of international protection. The purpose of the essay is to examine the differences between the three grounds of protection that are found in the Swedish Alien?s Act. Central questions have been whether the origins of protection statuses granted in this act are national or international, as the UN convention relating to the status of refugees and also the progress of the European Union?s Common European Asylum System both are affecting the Swedish legislation.

Studie av skyddsavstånd mellan bergvärmeanläggning och skyddsobjekt i ett vattenskyddsområde

During installation and operation of a geothermal heat pump system leakage of an antifreezing agent can appear in a borehole and leak out in surrounding groundwater. To guarantee high quality drinking water for generations to come Sweden has dedicated some areas as water protection areas. The local authority gives permits for the installation of heat pump systems within water protection areas. Before giving a permit the local authority makes an evaluation of the risks involved in installation and operation of the system within the area. By keeping a certain distance between the protected object in the area and the heat pump system the risk of polluting the protected object with an anti-freezing agent can be reduced.This thesis makes a comparison between three different methods of calculating an appropriate distance between the protected object and the heat pump system.

Vattenskydd och krisberedskap hos allmän dricksvattenproduktion : Skydd av täkter, tillgång till reservvattentäkter och andra nödvattenlösningar hos svenska vattenproducenter

The objective of this report was to analyse and compare vulnerability and preparation in Swedish municipal drinking water production, in case the commonly used water sources were inoperative. Methods used were a questionnaire and a less extensive study of regulations for water protection areas. The questionnaire was answered by 41 Swedish municipalities. A handful of them were companies co-owned by a few municipalities. Only one out of four municipalities had source protection areas to all their water sources and for many sources the protection was not satisfactory.

Gränsen mellan en anställds lojalitetsplikt och yttrandefrihet : - var går den?

The use of social media has increased considerably in recent years and has also caused some problems. It has been notable cases in the media where employees adversely criticized their employer on social networks, which subsequently led to the dismissal of the employee. The purpose of this study is to investigate an employee's right to express themselves about their employers in various forms but the main focus will be on social networks. The study investigates employees on both private and public sectors.Employees have a duty of loyalty to their employer, which means that they must be loyal to their employer and not deliberately harm them. The reason that employed comment his employer on social networks has its basis in that they also have freedom of speech and it is raised in such a case, a collision between their rights and responsibilities as an employee.The employees also hold a critique right entitling them to publicly criticize the employer and its activities.

Verksamhetsrelaterade uppsägningar i Sverige och Polen : En komparativ studie

This thesis investigates similarities and disparities between Swedish and Polish Labour Law concerning dismissals due to operational requirements and group redundancies. The study focuses on three important elements where the employers? liberty is legally infringed upon in a procedure of notice. These elements concerns the legal conditions of notice that must be fulfilled, the rules of the procedure and the rules for employment protection that is granted in connection with dismissals due to operational requirement or group redundancies. In the thesis there is a comparative map that outlines the most important rules within the Swedish and Polish legal systems concerning the subject.

RCC-Jordfelsskydd, mätmodul för övertonsanalys

The majority of all power cuts that affects individuals and communities are caused by earth faults on the power transmission lines at 10kV and 20kV level [1]. If these power cuts could be eliminated, less disturbances and interrupts would lead to large amounts of money savings.Swedish Neutral has developed such a protection system. When an earth fault occurs power is injected into the neutral point of the transformer. The RCC (Residual Current Compensation) protection calculates a compensation current exactly 180 degrees out of phase to the fault current. Doing this, the voltage at the fault location becomes very close to zero, without affecting the power transmission.The protection system can only compensate automatically for the fundamental frequency (50Hz), and manually for the 3rd, 5th, 7th and 9th harmonics.

En Fallstudie av Implementeringen av EU:s Minoritetsskydd

The intention of this thesis in political science is to understand how the European Union fights and prevents discrimination against the Roma minorities in Sweden and Romania, and how the implementation works in reality. The study consists of defining what it means to be objectively discriminated, what ethnicity really means and how the implementation process consist of a comparison and statement has been made by the national governments and comparing how two socioeconomically different member states handle EU directives and implement them in Sweden and Romania. The main findings of this study was that EU policies lack the capital and explicitness that is needed for great results to be accomplished and that the governments in both countries have different issues with implementing the protection of the human rights and Roma culture, and that EU needs to be more practical and develop in a faster pace. .

Socialarbetares förståelse av våld i nära relation : En vinjettstudie med barnavårdsutredare

Social workers ideas about what domestic violence is influence their ability to recognize vio-lence in cases where this occurs. Social workers awareness and understanding of domestic violence can also influence the handling of these cases. Education on the subject domestic violence can increase social workers knowledge about, awareness and handling of violence. The present study aims to investigate how social workers in child protection investigations understand, recognize and interpret domestic violence and which interventions the social workers suggest. This is a qualitative vignette study in which semi-structured interviews was carried out with social workers working with child protection investigations.
