This thesis is a case study of the search function on the University of Uppsala?s web site. The search function in this study was chosen since it exists on a large and complex web site and there were apparent lacks in the old version of the search function. The thesis highlights some of the problems that can appear in the development of a search function on a local site. One interesting find is that one of the most difficult issues is organizational and not technical.
Lakvattenrening och kontroll vid deponier : granskning och sammanställning
If not purified leachate from landfills would cause damages on the environment. At most landfills in Sweden local treatment of leachate is achieved, at the rest the leachate is transported to sewertreatment. While no comprehensive legal provisions for discharge exist in Sweden there is a difference in discharges between the installations for landfill. If no comprehensive legal provisions is produced guidance must improve.Treatment of leachate and self monitoring system at fifteen installations in Sweden has been studied and compared. A study of literature about different treatment solutions has also been performed.
Stärkelsenedbrytningens betydelse för mjölkkors konsumtionsmönster och mjölkproduktion :
Feed intake in dairy cows is regulated by a variety of factors influencing hunger and satiety.
One of the regulation systems includes the short chain fatty acids produced during feed
degradation in the rumen. Starch can be digested either in the rumen where short chain fatty
acids are produced or in the small intestine where glucose is the end product. Since glucose
does not have the same effect on satiety that short chain fatty acids have, the site of starch
digestion might be an important factor that affects feed intake and milk production. The aim
of this study was to investigate the effects of site of starch digestion on feeding behaviour
(feed intake, consumption time, and eating frequency) and milk production.
Because feeding behaviour is closely connected to the cows? environment, the study also
included observations of behaviour.
Three different feed rations were compared.
Byggandet av kundrelationer med hjälp av Internet: en fallstudie om resebyråer
The purpose of this thesis was to find out how travel agencies work with relationships to their customers on the Internet. A case study with two companies was conducted, Ticket and Resia. In all four interviews were done, two in every company that served as basis for our conclusions. The study showed that it is important for travel agencies and other types of companies to create awareness of their web site in as many ways as possible and make it easy for the customer to find the web site. The contents on the web site have to be of current interest, it should be well structured and the usage of the web site should be easy.
Marte meo-metoden på behandlingshem : en kvalitativ studie utifrån föräldrars och behandlares perspektiv
This study aims to explore parents and treatment personnels experiences of the Marte meo methodat a family treatment home. Three retrospective interviews were made with parents whoexperienced Marte meo treatment, as well as four interviews with treatment personnel. The purposeof the Marte meo method is to develop the interaction between parent and child. Previous resultsfrom studies show that treatment with the Marte meo method could provide positive effects to theparent child relationship. The results in this study have been analyzed by using parts of attachmenttheory, the salutogenic perspective and the term intersubjectivity.
Optimering av indunstningsprocess
The wastewater treatment plant at GE Healthcare's facility in Uppsala deployed a three step vacuum evaporator in 2007. The purpose of this was to pre-treat wastewater containing amines. The purpose of this thesis was to optimize thisprocess by reducing the amount of concentrate without releasing more nitrogen tothe environment and to examine if density could be used as a measurement of whenthe process should be ended.To create a foundation for optimization six test cycles were conducted with samples taken from all three steps. Both concentrate and condensate were tested as well as the incoming solution. Furthermore, the thesis has been expanded with a benchmarking part examining two different evaporators.
?Rätt avlopp på rätt plats? : ? Livscykelanalys av tre enskildaavloppsanläggningar
?Rätt avlopp på rätt plats? ? Livscykelanalys av tre enskilda avloppsanläggningarProblemen med övergödning i Östersjön och i Sveriges insjöar är stort och enskildaavlopp pekas ut som en central aktör, framförallt beträffande fosforutsläppen. I Sverigefinns det ungefär en miljon enskilda avloppssystem och nästan hälften av dessa har enså pass bristande vattenrening att de inte uppfyller gällande lagstiftning. Utvecklingenav nya tekniker för rening av avloppsvatten har länge strävat efter att minska utsläppenav övergödande ämnen, detta ibland på bekostnad av andra utsläpp, så somväxthusgaser och försurande ämnen.Det här examensarbetet har därför med hjälp av metodik från livscykelanalys (LCA)utvärderat tre enskilda avloppssystem med tanke på deras utsläpp av växthusgaser,försurande gaser samt övergödande ämnen. Då misstanke också fanns att de lokalaplatsegenskaperna påverkar de enskilda avloppssystemens totala miljöpåverkan,utfördes även en intervjustudie med ett antal av landets kommuner.

Integreringsanalys av robot och arbetsstation på ITT Water & Wastewater
ITT Water & Wastewater ställer höga krav på kostnadseffektiv produktion vilket är en starkt bidragande orsak till att företaget är världsledande på sin marknad. För att erhålla kostnadseffektiv produktion har kombinationen människa robot visat sig vara framgångsrik.Examensarbetets syfte var att ta fram underlag åt ITT Water & Wastewater för att ta beslut om frigörande av indirekt personal vid line 15:s isoleringsstation på Elmotorverkstaden. Syftets uppfyllande stöttades av de underbyggande syftena att försöka höja robotens utnyttjandegrad samt reducera isoleringsmaskinens omställningstid.Arbetet bygger på kvalitativa och kvantitativa data i form av mätningar, intervjuer och egna observationer. Med stöd av erhållen data lyftes fyra olika förslag fram. Förslagen understryktes bland annat av integrering av arbetsmoment, förhöjd automatiseringsgrad och outsourcing..

Utvärdering av substrat för biogasproduktion
The purpose of this study was to evaluate the different substrates that enter the digestion on Sundet wastewater treatment plant for production of biogas.This work have done an analysis of data about the biogasproduction from January 2012 to feburari 2013, this showed that the food substrates has a greater gas production than internal sludge.Through laboratory test the VS, TS and COD values for all the substrates used in the biogas production could be determinded. But the COD-method was less optimal for analysis of fat and food, therefore it optimized the method for fat but due to time constraints, this could not be done on the food substrates..
Leveranslogistik på byggarbetsplatsen
Problem: How do delivery logistics work in practice at the building site?
Where are the big problems? How to make building logistics more
effective? Do the site management and the haulers agree about
questions concerning both parties? What is possible to gain by
using better logistics? Is it possible to gain time with better
logistics and by that reducing the costs?
Purpose and aim: The purpose is to discover if there are any disagreements between
the site management and the haulers. If disagreements occur they
will be examined and probable measures based on the problems
will be suggested. Another intention is to bring key ratios
concerning time spent for deliveries forward. One aim is to update
a similar report made in 1972.
Dubbelkönighet hos mört : normalt eller miljöinducerat?
A number of chemical agents, and their degradation products, have been
recognized as having estrogenic activity on animals. On fish they interfere with
endogenous estrogen and in many cases mimic its activity, thus increase estrogenic
reponse, with elevated levels of vitellogenin. Hence they are called Endocrine
Disrupting Chemicals, EDCs. Vitellogenin levels is often used as a biomarker of
exposure to estrogenic pollutants. Wastewater from sewage treatment works
contains chemicals known as EDCs, and there are evidence of roach (Rutilus
rutilus) living in recipients of such wastewater having traits of both gender, i.e.
oocytes in male gonads (intersex) on histological examination.
This study was done on roach living in Lake Funbosjön Uppland, Sweden.
Raä 977 - En lokal och tre aktivitetsytor. : En tvärvetenskaplig undersökning av Raä 977 vid Vojmsjön i Vilhelmina socken
This candidate thesis concerns the ?all but forgotten? material from the bronze age site named ?Raä 977, Hansbo 1:3, Vojmsjön, Vilhelmina?. During 1975-76, an archaeological dig was carried out by Västerbottens museum led by Ulla Walukiewich in an attempt to preserve the information the site held, before it was destroyed by the erosion brought on by the recently regulated sea ?Vojm? (Vojmsjön). The archaeological dig yielded a stunning amount of finds, samples and information previously unknown.
Structure and tree diversity of lowland limestone forest on Seram Island, Indonesia
There have previously been very few studies of forests on Seram Island in the Eastern Indonesian archipelago and none before on lowland limestone primary forests. The COLUPSIA project on collaborative land use planning has therefore chosen Seram as one of two project sites. The objective of the COLUPSIA project is to establish collaborative and equitable land use planning. In order to achieve its objective the COLUPSIA project aims to improve understanding of traditional resource management and how it interacts with governmental systems, as well as enhancing knowledge about tropical landscapes and ecosystem services.The aim of this study was to contribute to the COLUPSIA project through describing lowland limestone forest on Seram Island in respect to (1) forest structure, (2) tree species richness and (3) tree species composition. We set up 5 plots, each of 0.2 ha, at one site, Mawalai, and collected data on tree variables (tree diameter ?10 cm) as well as for some other life forms and environmental data.
