The web has made an incredible amount of unorganized information available to anyone. There are search engines that help us structuring the information, but it is still difficult to find what you search for on the web. The purpose of this master's thesis is to investigate whether the already existing techniques for automatic indexing are suited for the new information retrieval context on the web and how the choice to support these techniques, or not, affects the search results. This is examined through a literature study on automatic indexing and other related concepts, such as information retrieval and information searching on the web in order to get a theoretical frame to the work and by an observation of the search engine HotBot to approach the purpose of the thesis. The observation is carried out by searching HotBot's database and investigating the search results in order to try to identify patterns that can reveal something about how HotBot's automatic indexing is done.

Chronic obstructive pulmonary disease (COPD) is a chronic lung disease. The disease is the fourth leading cause of death and more than 5 percent of the adult population worldwide is affected.The aim of this study was to investigate the association between periodontitis and COPD.Search for material for the literature review was done in the medical database PubMed where the keywords were: "Chronic obstructive pulmonary disease" and "Periodontal health or periodontal disease". The result is based on twelve studies that were extracted and analyzed. The studies have investigated pocket depth, attachment loss, plaque index, bleeding on probing and bone loss. Ten studies compared a COPD group with a healthy control group, one study compared two COPD groups and one study examined a COPD group and a group with other lung diseases.Most studies found that people with COPD had a higher incidence of pocket depth, attachment loss, plaque index, bleeding on probing and bone loss.

Bakgrund: N?jesparker, som Liseberg med ?ver 2,2 miljoner bes?kare ?rligen, ?r v?xande turistattraktioner med stor potential. De bidrar till h?llbarhet genom sociala, milj?m?ssiga och ekonomiska initiativ men st?r inf?r utmaningar som s?songsberoende, s?kerhetskrav, teknologiska f?rv?ntningar och personalhantering. N?jesparker beh?ver ?ven hantera stora m?ngder avfall, energi- och vattenf?rbrukning samt resursintensiva byggnationer.

The aim of this thesis is to use the bibliometric method author cocitation analysis (ACA) and investigate the cognitive structure in a research field, which is called the intellectual base. The research field in this investigation is social psychology. The main question is: what is the nature of the cognitive structure, which contains of the intellectual base. This question is divided in two sub questions: ? Which are the most prominent authors in the research field? ? Which sub areas, based on groups of the most cocited authors in the research field, can be identified?An investigation with ACA is used to describe the general experience of consensus of later authors in a research field.

Projektet visar hur man med relativt lite kunskap om programmering kan ta fram en lo?sning som ba?de a?r cross-platform och enkel att underha?lla och vidareutveckla med ytterligare funktioner i framtiden. Systemet a?r gjort i Filemaker Pro 13/14 som ocksa? a?r klienten fo?r Mac OS X och anva?nds fo?r mobila enheter via Filemaker Go 13/14.Personalen pa? kostymavdelningen pa? NorrlandsOperan har tidigare arbetat med en struktur da?r information och bilder kring produktionen sparats i olika Excel eller Word-dokument fo?r att sen sparas pa? en gemensam filserver. Detta arbetssa?tt skapar problem kring dokumentation, att hitta information och att jobba mobilt.Lo?sningen a?r framtagen fo?r att understo?dja personalen i deras arbete och fo?ljer en tydlig ordning med vilka objekt som a?r relaterade till vilka andra objekt.

The town of Karlstad has a long term project called Vision 100 000 which aim is to increase the population towards 100 000 inhabitants. This will of course put a strain for the town?s energy distribution grid. This is a work about trying to predict the grids power usage would be for the next five years if the city building plan is finalized. Those predictions are mainly going to be done through calculations with a database program called Facilplus and by checking the measured history of power usage per hour on certain selected customers by the program CustCom.

Flera forskare lyfte att f?rskolan har stora m?jligheter att arbeta f?rebyggande och h?lsofr?mjande med barns psykiska h?lsa. Trots detta visade Folkh?lsomyndigheten i ?rsrapporter att den psykiska oh?lsan g?r l?gre ner i ?ldrarna och att k?tiderna till barn- och ungdomspsykiatrin v?xt. Det framkom att det fanns en kunskapslucka kring barns psykiska h?lsa och oh?lsa inom f?rskolans kontext och forskare ans?g att barn befinner sig i milj?er och grupper som inte alltid ?r sj?lvvalda.

Två grundläggande paradigm inom datavetenskap är objektorienterad programmering och relationsdatabasteknik. En kombinering av applikationer gjorda i ett objektorienterat programmeringsspråk med den beständighet och funktionalitet som ges av relationsdatabaser är en möjlig vidareutveckling av ens kunskaper inom dessa områden. Kombinationen av dessa båda förutnämnda paradigm innebär åtminstone ett problem som uppkommer då en relationsdatabas lagrar data i tabeller och en objektorienterad applikation lagrar data i objekt. Detta problem kallas objekt/relations paradigmens missanpassning. På grund av detta problem så måste kopplingen mellan paradigmen skötas av ett ramverk av något slag.

Fysisk aktivitet ?r viktig. Uppsatsen bildades d? vi ville unders?ka hur fritidshemmen arbetar med fysisk aktivitet och m?rkte att det finns v?ldigt lite forskning om fysisk aktivitet p? fritidshem. Syftet med studien var att f? kunskap om l?rarna i fritidshemmets arbetss?tt och till hj?lp har vi anv?nt tre fr?gor; ? Vad ?r l?rare i fritidshemmets uppfattningar av riktlinjer om elevers fysiska aktivitet enligt l?roplanen? ? Hur arbetar l?rarna i fritidshemmet f?r att bidra till att ?ka elevers fysiska aktivitet i fritidshem? ? Vilka f?ruts?ttningar det finns f?r elevers fysiska aktivitet p? fritidshemmet enligt l?rarna i fritidshemmet? Genom enskilda semistrukturerade intervjuer med ?tta legitimerade l?rare i fritidshem samlade vi in material d?r vi unders?kte deras f?rst?else av Lgr22s riktlinjer, deras strategier f?r elevers fysiska aktivitet samt f?ruts?ttningar de har f?r fysisk aktivitet. Teorin vi utgick fr?n var det salutogena perspektivet, begreppet r?relsegl?dje, begreppet KASAM samt barndomssociologiska perspektivet.

Background: Diabetes mellitus is one of today's major public health problems, affecting up to 347 million people worldwide. Several studies have shown a correlation between hearing loss and diabetes mellitus. However, it is still unclear whether this correlation differs between type 1-diabetes and type 2-diabetes.Purpose: The purpose of this study is to investigate whether there is any difference in prevalence of hearing loss in type 1-diabetics versus type 2-diabetics.Method: A meta-analysis was performed based on ten studies that were identified through the database PubMed and through manual searching of references. Odds ratios for the risk of developing hearing loss were calculated in each study. Pooled odds ratios were calculated using a random effects model.Results: Pooled odds ratios indicates that both type 1-diabetics and type 2-diabetics are more likely to develope hearing loss compared to non-diabetic controls.

The objective of this study was to contribute with suggestions of nature preservation managements of selected forest objects of high nature values managed by the Swedish state-owned forest company Sveaskog. Many forests with high natural potential are relatively rare today due to modern forestry, where wood production is the main purpose. Sveaskog?s policy is to consider and to priority nature conservation on valuable objects. This assessment includes objects that in the future may develop into nature reserves.

Denna kvalitativa studie unders?ker vilka motiv som ligger bakom gymnasieelevers val att l?sa ?mnet svenska som andraspr?k, sva, och vilka erfarenheter de har med flerspr?kighet i klassrummet. Studien har en fenomenologisk ansats d?r elevernas livsv?rldar och dess spr?kliga repertoarer anses p?verka elevernas beslut och f?rh?llnings?tt (Busch 2017). Detta inneb?r att elevernas uppfattning om ?mnet sva och deras inst?llning till flerspr?kighet p?verkas av deras tidigare erfarenheter.
