HIV/AIDS upptäcktes i början av 1980talet och utvecklades snabbt till en omfattande epidemi. Värst drabbat är Afrika söder om Sahara med 2/3 av världens cirka 40 miljoner smittade. Uganda, som ligger norr om Victoriasjön, var bland de första länderna att rapportera om HIV-fall och hade under 1990talets början en HIV-prevalens på omkring 20 %. Sedan dess har man lyckats minska spridningen av smittan och uppger idag en prevalens på omkring 4 %. Uppsatsen syftar till att se på vilka preventiva åtgärder mot spridningen av HIV/AIDS som genomförts i Uganda och i möjligaste mån deras kostnadseffektivitet uttryckt i USD/förhindrat fall av HIV-smitta.

The Individual Program (within the continuation school) in Sweden is the third largest. Its purpose is that the students, who for some reason haven?t been able to be admitted to a National Program, shall get the chance to improve their possibilities to attend one. The difficulties the students, who are admitted to the Individual Program are carriers of, have a wide range. The purpose of the Individual Program is that no one should be excluded from any continuation school.

Approximately 60 million cubic meters of round wood are transported every year with trucks in Sweden and stand for 15 % of all truck transportation in the country. The big amount that is transported results in many haulage companies works in different parts of the country with different conditions to get a good flow on their transports. Today the transport pricing is very general and the payment consists of the unit round wood they are transporting and the distance of the transport. The purpose of this study were, from the freighter and the haulage company?s perspective, try to find ways to change the today applied transport pricing to more differentiated and compare them to historic payment of transportation.

This thesis describes a method of measuring axial magnetic leakage flux in an operational hydropower generator. Axial magnetic leakage flux is the magnetic flux at the ends of a rotating generator, which goes through the stator parallel to the rotor axis. This flux can cause circulating currents in the stator iron, giving rise to losses, and can in the worst case overheat a generator, causing it to melt down. To measure the axial flux, and how it affects the generator temperature, a measurement system was constructed on behalf of Vattenfall. The system consists of search coil sensors and a signal-processing unit with amplifiers and active filtering.  To confirm the behaviour of the axial leakage flux and the functionality of the measurement system, a test installation was made.

Inför detta arbete hade vi en förväntad leverans att utgå ifrån, en stor del av dessa förväntningar låg i att redogöra för användningen av adresserings- och identifieringsteknik inom Sandvik SMT?s (Sandvik Materials Technology, affärsområde inom Sandvik AB) lagerytor. Under arbetets gång har dock strukturen förändrats och denna rapport kom att bygga mer på utformingen och styrningen av ett lager. För att på ett effektfullt sätt visa på, hur ett lager under optimala förhållanden utformas och styrs så tog vi litteraturen till hjälp och utformade en modell som vi sedan använt i vårt arbete. Syftet med detta examensarbete kom därför att handla om att skapa en modell för att utforma och styra lager inom industriell verksamhet.Modellen tar upp de faktorer som är viktiga för utformning och styrning av befintliga lagerytor eller nya lagerytor som skapas.

Syftet med denna litteraturstudie a?r att underso?ka hur la?ssva?righeter och la?sinla?rningsproblematik yttrar sig, samt hur framga?ngsrik undervisning organiseras med detta i a?tanke. Studiens resultat baseras pa? tidigare forskning och avser besvara fo?ljande forskningsfra?gor:Hur visar sig la?ssva?righeter i de fo?rsta a?rskurserna (fo?rskoleklass och grundskolans a?rskurs 1-3)?Hur kan la?rare arbeta fo?r att fo?rebygga uppkomsten av la?ssva?righeter och underla?tta fo?r elever med sa?dan problematik?Studien visar att la?ssva?righeter ga?r att uppta?cka redan hos barn i fo?rskoleklass och att det pa? sa? vis ga?r att fo?rutse hur la?sutvecklingen kommer att fortskrida. I de tidiga a?rskurserna kan sva?righeter bli synliga redan i den grundla?ggande la?stra?ningen och hindra eleven fra?n fortsatt utveckling.

AbstractDegree thesis Solid content in Lime Mud By Andre Flodin Process operator program ? Umeå University 17/6 ? 2014 Pages: 21A thesis was made on Billerudkorsnäs production unit in Karlsborg where lime kiln in the causticising department of chemical recovery plant does not meet the required production. Causticising department is the final step in the chemical recycling unit. There, the filtered green liquor is mixed with lime to recover the cooking chemicals used in the pulp factory. The cooking liquid is called white liquor.

Smärta påverkar människans livskvalitet och medför både fysiskt och psykiskt lidande. En demenssjukdom ger såväl fysiska funktionsnedsättningar som psykosociala beteendeförändringar.I omvårdnaden av patienter med demenssjukdom finns svårigheter med att identifiera och bedöma smärta på grund av de funktionsnedsättningar sjukdomen innebär. Studiens syfte är att undersöka hur vårdare identifierar och bedömer smärta hos demenssjuka patienter. Metoden är en litteraturstudie. Datamaterialet innehåller 13 vetenskapliga artiklar.

This report shows methods and workflow when exploring the potential to change Outotecs HCD Silver Electrolysis machine to a module type. It?s done as an attempt to lower the workshop and installation costs and to give customer a more accurate prize directly. To do this a concept was produced which was set to a stress test. Additional objectives were to investigate freight and installation procedures, pneumatic connections and to calculate the difference in cost.Once the concept, a reinforced type of the original frame, was chosen stress tests in computer simulations were made and appropriate alterations were made.

In 2007 the Prevention Unit at Södermalm in Stockholm started a group activity for parents and children. The group activity?s intention is to offer families support in their early interaction. This study is a part of providing knowledge about this intervention. The purpose of this study is to describe and analyze the stories which are produced by five participants in a support group for parents and children.

The increasing administration in IT-systems is the target of much debate today. It is viewed as taking time from what is considered to be managers? real tasks as well as resulting in an ineffective and stressful work environment. This view of IT-systems as problematic and time consuming can also been found among unit managers in a municipality in the north of Sweden. To be able to understand why IT-systems are perceived in this way this study?s aim has been to find what leads to this view.

On Ericsson Ltd in Borås a wireless communication system called MINI-LINK? is produced. In order to sell their product with the best possible quality guaranty, there is a signal processing circuit called ATLAS implemented in the system. This circuit would eventually be useful in the production and for the repairs of the radio units. Our commission was to examine the possibility for this use.

The result of this master thesis report describes the advantages and the drawbacks that will arise when implementing an Ethernet based intercommunication system in military vehicles. The report presents a possible solution and describes how different sound applications will be implemented into the suggested solution. The report show that IP LAN in vehicles leads to more advantages than drawbacks. The main advantages are that all kind of media can share the same LAN and that there is a lot of knowledge of this technique in the civil area. The main drawback is about delay.

Inom processindustrin finns en etablerad reglerhierarki där basreglering sker med PID-regulatorer och där avancerad, multivariabel styrning sköts av MPC-programvara. Steget mellan dessa två nivåer kan upplevas som stort. För mindre och snabba multivariabla processer undvikes helst en multivariabel ansats, med försämrad reglering som följd. På Preem AB har detta upplevts som ett problem. Syftet med examensarbetet har varit att utveckla en alternativ, multivariabel styrstrategi för en process med ett mindre antal reglerstorheter som interagerar.

This study is based on interviews with heads of unit, care staff and senior representatives from a total of six people. We have in this study directed our focus on care quality in the elderly as a concept in development. It appears, when the elderly do not have any dependents, it is even more important that staff supports some extra where no relatives are involved.Quality of life is the broader concept of good quality care and where a good quality of care is a necessary condition for a good quality of life. According to the social services care is the target that older people will live a good life and be allowed to live in a safe environment, which we intend to investigate in this study. Opportunity for greater influence should now be given to older people and their families on how interventions should be designed and implemented.
