Optimering av biologisk fosfor och kvävereduktion i ett reningsverk för hushållsspillvatten

In connection with Henriksdals wastewater treatment plant (WWTP) a smaller plant is situated called Sjöstadsverket where new methods for wastewater treatment are tested and evaluated in different process lines. On one of the lines experiments with enhanced biological phosphorous removal (EBPR), have been carried out to evaluate if it is a good alternative to traditional chemical phosphorus removal. This thesis evaluates the results from the experiments conducted during fall 2005.The incoming water from Hammarby Sjöstad consists of only household wastewater, which gives a wastewater with high concentrations of nutrients and organic carbon. This is partly positive, because one of the limiting factors for effective biological phosphorus removal is the lack of easily biodegradable organic carbon. The high concentrations of ammonium and phosphorus demand a high reduction to achieve the requirements of outgoing concentration.To optimize the process experiments with different recirculations and different aeration techniques have been made.

Septisk tenosynovit i kotsenskidan hos häst : en retrospektiv studie av 21 hästar

Septic tenosynovitis involving the digital sheath is a relatively common problem in the horse and the prognosis has been considered as poor. However, there are only few studies confirming this. The purpose of this study is to increase the knowledge about the prognosis for septic tenosynovitis in the digital sheath. The literature indicates that half or a bit more than half of the treated horses will return to previous use. The recommended treatment is debridement of the wound, lavage and sometimes application of drains and broadspectrum antibiotics. The prognosis is considered as worse when the infection is established.

Undersökning av miljöstatusen i Gothemsån / Dalhem i anslutning till utsläpp av lakvatten från sopdeponi i Roma 2010

In October 2010 it was discovered that leach water had been released from a waste deposit directly into a ditch during a period from March until October 2010. The river Dalhemsån runs close to the waste deposit, just about 10 meters from the ditch. By studying the benthic fauna it was discovered that the environmental status of Dalhemsån is bad in this part of the river, but the discharges of leachate from the waste deposit does not seem to have deteriorated the water further since May 2010..

Behandlingsmetoder vid hopparknä: en litteraturstudie

Jumper´s knee is a common overuse injury due to repetitive microtrauma to the patellar tendon. It is especially common among athletes who are involved in sporting activities that involve jumping or fast running. The term jumper´s knee was adopted after Blazina published his original paper in 1973. Its pathology can be considered as a partial or total rupture of the patellar tendon in one of its three insertions. The aim of this literature study was to review the methods used to treat this condition and the results obtained focusing on pain relief and returning to previous sport or level of activity.

Förklaringsmodeller och behandlingsmodeller kring mäns våld mot kvinnor : En litteraturstudie

Young men who commit sexual abuse is a complex topic. This study is based on litterature on the subject and the material is processed through a qualitative content analysis. The study aims to study how the litterature describes the reasons why young men commit sexual abuse. It also aims to explore what is described to be effective treatment of young men who committed sexual abuse. The study found that most of the young men who commit sexual abuse comes from families where violence and psycohological abuse occurs. Many have themselves been victims of sexual abuse.

Rissepareringens effekter på viltets nyttjandegrad av GROT

Successful forest regeneration is a prerequisite for sustainable forest management. Therefore, it is important to prevent browsing damage on the commercially important tree species Scots pine. In this study I have tested a new alternative way to increase the available amount of forage and increase the use of these resources by especially moose. The method is based on a slash treatment at harvest, where the accessibility of slash as forage is increased during final felling or commercial thinning by gathering the slash and putting the Scots pine slash on top of the slash piles. This study has compared the availability of forage, the amount of browsed biomass and the number of fecal pellet groups between conventional and slash treated stands after final felling and commercial thinning in southern Sweden.

Sverigedemokraterna i kommunerna 2006 ? En empirisk studie av de kommunala förhållanden som gynnar partiet

The Sweden Democrats achieved great progress in the latest election in the Swedish municipals. The party is now closer than ever concerning reaching the Swedish parliament. This thesis examines the Sweden Democrats in the Swedish municipals with the aim to find out which municipal factors that led to their progress. By looking at the percentage share of unemployment, the percentage share of foreigners, the percentage share of education, average income, traditional political colour, average age, criminality, early representation of a party hostile to foreigners, the municipal type and the sickliness in the municipals I find out which factors explain the progress of the Sweden Democrats. The thesis is an empirical quantitative study build on statistics by the help of regression analysis and diagrams.

Hantering av kugghjul : -Vägen från mjukbearbetning till hårdbearbetning

AbstractThis master thesis was performed at Scania transmission department in Södertälje, where the manufacturing of gears is done. Today a large amount of manual handling is performed between the machining and the hardening process. Most of the manual handling is done at the heat treatment department. The purpose of this master thesis is to give a suggestion on how to reduce or eliminate the manual handling at the heat treatment department. The possibility to use the same packaging throughout the processes will also be investigated.

Effekter av befintliga och eventuella framtida läkemedelsbehandlingar på morbiditet och mortalitet hos patienter med hjärtsvikt.

Background:  Heart failure is a multidimensional phenomenon with high mortality. Heart failure is treated with angiotensin converting enzyme (ACE) - inhibitors or angiotensin receptor blockers (ARBs) that counteract neurohormonal stimuli that occur in heart failure, as well as providing vessel dilatation, which reduces symptoms and the need for hospitalization and increases survival. Despite this, only about 50% of heart failure patients survive 6 years after diagnosis with drug therapy, and as heart failure is increasing globally, due to improved care and treatment and increasing life expectancy of the population, there is a great need for new drugs such as LCZ696 that acts by dual inhibition of the renin - angiotensin - aldosterone system and neprilysin inhibition.Objective: The aim of this literature study was to evaluate the efficacy of current treatment and possible future treatments on mortality and morbidity in heart failure patients.Results: The examined articles show that treatment with ACE inhibitors in patients with symptomatic heart failure reduces the risk of total mortality by 16% over 3.5 years, reduces all-cause mortality or hospitalization due to heart failure with NNT (number needed to treat) = 10.4 over 3.5 years and increases median survival by 9.2 months over 12.1 years in patients with asymptomatic heart failure. Treatments with high-dose ACE inhibitors reduce mortality and hospitalization because of cardiovascular causes and hospitalizations from any cause by NNT = 30 over 3 years. Beta-blockers reduce sudden death and total mortality and cardiac death or non - fatal myocardial infarction with NNT = 38 and NNT = 23, respectively, over 12 months.

Identifiering av fosfatfosfors käll- och flödesfördelning i ett litet jordbruksområde

Eutrophication of lakes and streams are nowadays a well known environmental problem and implies an enrichment of the nutrients phosphorus (P) and nitrogen (N). Phosphorus is considered to be the most important component for the growth of aquatic plants and leads in too large quantities to an intensification of growth. Phosphate (PO4) is the fraction of phosphorus that can easiest be taken up by plants and thus have the greatest impact on eutrophication. Increased plant growth in lakes and unfavorable conditions for aquatic animals are two examples of negative consequences. A significant portion of the increased nutrient supply to nearby water can be derived to phosphate leaching from agricultural areas, where private sewers and agriculture is two main sources.

Sjuksköterskors erfarenhet av att vårda patienter med självskadebeteende

The Swedish industrial society has left several areas with contaminated soil and water which today is of danger for the environment and human health. One of these areas with contaminated soil and water is the region where the former Glava glassworks operated during 1859 to 1939. The main object in this study has been to study the responsibility for the contaminations according to the Environmental Code. The method used is a qualitative content analysis of relevant literature to answer the following questions:What types of contaminations can be found in the area of Glava glasswork and what health issues can these cause?What kind of activity has been conducted in the area that have caused the contaminations in soil and water?According to law, what are the responsibilities for the contaminations in soil and water at Glava glassworks?The contamination in the region has been confirmed to originate from the glasswork due to the environmental engineering survey made in the area in 2009.

Trädgårdsterapi inom kriminalvården : en möjlighet för Sverige?

The main objective of this study was to investigate the possible design of a horticultural therapy program in Swedish correctional treatment facilities. In the USA the use of horticultural therapy in offender rehabilitation is much more frequent compared with Sweden. The aim of these programs typically contains education for inmates. Research has been made indicating that these programs can have positive effects on psychosocial behavior and on vulnerability to substance abuse among incarcerated offenders. In this study the examples of these programs was categorized and analyzed from three perspectives; Vocational, social and therapeutic horticultural programs.

Lund och medborgarna En studie över Lunds kommuns arbete med delaktighet och demokrati

At the moment, democracy enhancing projects can be seen everywhere on the municipal level. The purpose of this thesis is to explain how the city of Lund takes on this challenge, why they have chosen to carry out citizen councils and if these are a good way to intensify democracy and open communication channels between citizens, the administration and the elected officials.The theoretical framework consists of seven arguments for gaining citizen influence on policy, and as a counterweight three critical arguments that opponents of participatory democracy often use are added.After a survey over both the Swedish national trends in municipal renewal and the last years work in Lund, the analysis goes on showing that most of the arguments point to the disadvantage of the citizen councils. Even though legitimacy possibly is enhanced by the project, there are probably better ways to open up for more communication and intensify democracy in the local community..

X-it :en studie om f.d. narkotikamissbrukares erfarenheter

The purpose of this study was to get a client perspective of the different ways to exit from a different role as a drugabuser, and furthermore, how to maintain a drugfree life.The questions of issue were:- What kind of social-psychological conceptions rules the process?- Which motive powers are essential to maintain drug-independence?- Are there any difficulties on the path to social adaptation?Our research was based on interviews with eight persons; five men and three women, from a treatment home in the south of Sweden. The method we used was semi-structured and with a thematic questionnaire. We chose this form due to the fact that we did not want to influence the interviews, as we wanted to know the persons opinions.The result of our study showed that the interviewed persons have some difficulties to adjust in the society and to find new friends especially the interviewed persons with maintenance treatment. Marginal problems as, for example, the lack of not having a work or a home can complicate a further development for the group with maintenance treatment.

Hållbarhetsredovisning enligt GRI:s riktlinjer : En studie av två svenska statliga företag

What impact and effects are created by the placement of an international ranking? Could it be that a top rank is detrimental to an entire country's efforts to fight corruption?This bachelor thesis in political science is about Swedish corruption. In essence, so questioning the Transparency International's indexed rankings that placed Sweden in third place. Issues concern since if the third placement has created nonchalance and a careless mentality in Swedish government and in particular in the municipal operations. Research results show that Transparency International's rankings have low validity and low reliability and that the government is not acting sufficiently to prevent and fight corruption.
