Analys av vattenkvalitet i ett kommunalt badhus

Bath has been a part of human history for a long time. Today bathing/swimming inmunicipal pools is for people of all ages and it is possible to take swimming courses,exercise or enjoy recreation. The municipal indoor pool of Hogdalen in Sweden wasbuild in the sixties and has had problems with high levels of heterotrophic bacteria. Thefacility has two larger pools, one adventure park for young kids, two smaller bath tubsand a jacuzzi. To improve water quality UV light and coal filter were installed inOctober 2009 to the already existing purification system.

Närsaltsdosering till luftad damm : en åtgärd för ökad TOC-reduktion hos Skoghalls Bruk luftade damm

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.

Optimering av prestanda och utnyttjande av flertrådsteknik

The purpose of this thesis was to help the company Medius AB with optimization of selected parts in an existing system to minimize the execution time by implementing multithreading. The idea was to manipulate the code so that calculations could be executed at the same time. The main work in this thesis consisted of three optimizations. The first one was to reconstruct a big ?for-loop? so it would execute every loop's work in an own thread. The second optimization also was a reconstruct of a ?for-loop? so it could execute the work in different threads. The third and last optimization consisted of reconstructing a stored procedure on the database, so different parts of it each could be executed in an own thread to create data at the same time. To implement the optimizations Visual Basic .NET and its support for multithreading and connection-pools was used. The result of the optimizations meant that one of the modules could be executed more efficiently and it was 12 % faster. The other modules execution time was more efficient by 25 % faster. The meanings and requirements for this thesis are fulfilled by now letting the system make use of its resources in a better way..

Användandet av samlingsprover för att bestämma besättningsstatus för smitta med Dictyocaulus viviparus hos förstagångsbetande nötkreatur :

Infection with the bovine lungworm - Dictyocaulus viviparus - is occasionally a problem in Swedish cattle herds. The infection could act in synergism with other infections such as Corona virus to create a poorer welfare and productivity in cattle. Studies have shown that a diagnosis can be made with both the Baermann method and with an ELISA. In Norway diagnosis of BVDV on a herd level is attained through pooled serum samples. The question was raised whether pooled serum samples could be used in a similar fashion to attain status on a herd level for lungworm.

ini

Preporsition for bachelor thesis project, working from the inside and out. Emphasising spatial quality and experience, More or less ignoring form and program. I?ve had issues with these aspects in earlier project, the form or the program takes alot of place in the project. I haven?t tried this approach before, it?s an attractive thought to allow the project take a form of it?s own, enclosing those spaces i create.The initial concept was to place the pools on the ground (not digging them into the ground) making them volumes that divide and define spaces.

Nord Pools olika prisområden, samma marknad?

Sverige är på väg att förändras via uppdelning i flera prisområden på den Nordiska gemensamma elmarknaden. Många skandinaviska länder som agerar på Nord Pool är redan uppdelade i prisområden. Olika prisområden i ett land innebär att landet har olika elpriser på en och samma marknad, Nord Pool. För att definiera en relevant marknad kan man undersöka om olika prisserier följer samma långsiktiga trend. Syftet med denna uppsats är att undersöka om de länder som är uppdelade i olika prisområdena på Nord Pool tillhör en och samma marknad.

Restaurering av vattendrag :

SAMMANFATTNING Rinnande vatten har över en lång tid spelat en väsentlig roll för landskapets geomorfologiska processer och utgör viktiga livsmiljöer för djur och växtsamhällen. Vattendrag har bidragit till människans utveckling och välstånd. Sedan urminnes tider har vattendrags miljöer nyttjats som boplats, för vinning av energi, transport och fiske. Likt allt liv på vår planet är människan beroende av vatten. Betydelsen av vattendragen, som del av den hydrologiska cykeln, kan därför inte betonas nog. Genom mänsklig aktivitet har dock rinnande vattens egenskaper och landskapsbilden som helhet i många områden förändrats drastiskt.

Reglering av högfrekvenshandeln

SammanfattningHögfrekvenshandeln är ett mycket uppmärksammat och aktuellt fenomen. Många är skeptiska till högfrekvenshandeln vilket delvis kan bero på hur media har framställt det. Allmänheten känner en viss oro till högfrekvenshandelns och dess samband till marknadsmissbruk. Handeln sker på en fragmenterad marknad som gör det svårt med en hundraprocentig insyn på de svenska börserna. Därför vill författarna undersöka om regleringar bör introduceras för att skapa en säker och kontrollerad marknad i syfte av att undvika framtida krascher.Studiens primärdata har samlats in genom tre semi-strukturerade intervjuer med respondenter som är bekanta med högfrekvenshandel.

Att dela eller inte dela? : Vad som möjliggör respektive förhindrar produktdelningssystem

Product sharing systems is recently starting to become a more common phenomenon. Carpools exist in more than 40 Swedish towns and both Stockholm and Gothenburg have established bicycle sharing systems. Other products for which sharing systems have been established throughout Sweden are clothing and tools. From the point of view of the consumer, product sharing systems is a form of consumption which can be placed somewhere in between renting and privately owning a product, where the consumers usually pay a membership fee or a monthly fee to have access to the products whenever they need them. The concept is relatively new, and there are many products for which product sharing systems do not exist.

Simundervisning för praktiserande muslimska flickor : Hur olika sociala aktörer upplever att simundervisningen genomförs i den svenska skolan

Since Sweden can be considered to be a secular society it is interesting to investigate how different actors experience swimming education in the course syllabus of sports and health education, for practicing Muslim girls in middle and high schools. The investigation is based on qualitative interviews with sports teachers, practicing Muslim girls and the staff of the public swimming center in Växjö. The result shows that swimming education can be somewhat problematic, since the Muslim girls only want to attend lessons that are gender separated. In the public swimming center, there are no pools exclusively intended for women, and there are only a few times available for women every week. However, the teachers stress opportunities instead of obstacles, and the students? experience that their teachers are trying to create possibilities for them to have a gender separated swimming education.

QUALITY OF TACSI PLATELETS AND THEIR EFFECT ON THROMBOCYTOPENIA PATIENTS

 Conclusion:Medical treatment may have a role in platelet count after transfusion. Since the TACSI platelets passed the quality requirements, and the vast majority of patients platelet count increased after TACSI platelet transfusion, the TACSI platelets will replace the old method to produce platelets at the Uppsala University hospital.  Methods: A new approach that pools 8 buffy coats (TACSI platelets) that were separated into 2 units instead of 4-6 buffy coats pooled to 1 unit was investigated in this study. After the platelets were extracted from the buffy coats their quality was controlled and subsequently the platelet product was evaluated in 96 patients. Results: The results showed that 80 % of the platelet units passed the European quality requirements. Further, the platelet count was increased in most patients that received TACSI platelets. Conclusion: Medical treatment may have a role in platelet count after transfusion.

Störningsregimer vid Skövde övnings- och skjutfält : Stridsfordons påverkan på olika naturtyper i militära övningsområden

A lot of habitats have declined or disappeared as the old cultural landscape changed to the modern agricultural landscape of today. Places such as power line corridors, racing tracks, gravel pits and military training sites have become refuges for many species associated with the old cultural landscape. These sites have been exposed to ecological disturbances that create the same type of habitats that were found in the old cultural landscape.The military training sites in Sweden has an impressive diversity of species. Disturbances from the military exercises have created habitats that are important for a wide range of species.The purpose of this thesis is to study some of the ecological disturbances occurring in the military training sites of the Swedish Armed Forces and examine how they affect different types of habitats. The thesis explains through litterateur and field studies the reason to the rich biodiversity often found at military training sites.

Mobility Management : vad är det?

Mobility Management is about affecting and changing the demand of mobility. It?s not about what traditional planning?s been focused on; to supply for the demand. The demand of mobility is created by us humans since the traffic exists of us. That means that Mobility Management is about changing our needs.

Kväveomsättning i gräsmark med olika artantal och artsammansättningar :

This study was carried out at the Swedish University of Agricultural Sciences, Dept. of Agricultural Research for Northern Sweden. The aim of the study was to determine how plant species richness and diversity influence the nitrogen pools and nitrogen fluxes in the soil. Plant and soil samples from a biodiversity experiment in grasslands were used. Thirty plots with 12 grassland plant species (legumes, grasses, and non-legume herbs), combined from 1-12 species were investigated.

Presence of Japanese Encephalitis virus vectors in Can Tho City

Japanese encephalitis virus (JEV) is a significant vector-borne zoonotic pathogen, causing devastating encephalitis in humans. Its geographical range includes a majority of Asian countries and has also been recognized in some western Pacific areas. The main vectors of JEV are mosquitoes belonging to the genus Culex. Birds and pigs function as hosts and virus amplifiers, whereas humans are accidental hosts. Japanese encephalitis is commonly regarded as a rural disease.
