Modern forestry requires a high degree of machine traffic for clear felling and scarification operations. The machines most frequently used are big and the traffic often results in tracks on the forest ground. There are many small streams running through a forest, in connection to logging operations, machines might cross these frequently. These crossings could result in the erosion of fine particulate inorganic matter, which ends up in the stream. The aim of this thesis was to give a general description of small forest streams of order-one in the county of Värmland and to determine the frequency of machine tracks in small streams.

In the early 1990?s more and more companies of the Swedish public sector were exposed to competition, and this started the debate on how such actions might affect the business and even society.The first chapter examines how the public sector and especially health care, is financed and managed. We also explore what it means to be exposed to competition and find that there are many different ways of exposing the public sector to competition. The study examines dental care as an example of a market with both publicly and privately owned companies. The purpose of this paper is to explore how publicly and privately owned health care companies view their relationship with their consumers.

Introduktion: Ätstörningar som Anorexia Nervosa (AN) och Bulimia Nervosa (BN) innebär ett folkhälsoproblem och orsakar oral ohälsa. Vid ätstörningar har individen en störd kroppsupplevelse och försöker kontrollera sin vikt och kroppsform. Under de senaste decennierna har det skett en omfattande ökning i förekomsten av ätstörningar. Syfte: Att beskriva oral hälsa vid ätstörningar.   Frågeställningar: Hur påverkas den orala hälsan av sjukdomen AN? Hur påverkas den orala hälsan av sjukdomen BN? Metod: Designen är en litteraturstudie i området oral hälsa och ätstörningar.

The aim of the study was to describe how patients experienced communication, treatment and costs at the dental hygienist program at Högskolan Kristianstad. The study was based on a questionnaire that was made at the patient clinic. The questionnaire was conducted by the treating dental hygienist student after the treatment. The questionnaire was answered in the waiting room. Collection of the material occurred during the month of March in 2009.

Introduktion: På grund av extremt hög fattigdom har de orala hälsofrågorna haft låg prioritet i Tanzania. Vid en konferens 2004 i Nairobi om den orala hälsan i Afrika ställde sig Tanzania, tillsammans med andra Afrikanska länder, bakom det gemensamma beslutet att hållbara nationella program måste utvecklas för att främja oral hälsa. Detta beslut har varit en drivkraft till att delta i och utveckla nedanstående projekt avseende munhälsofrämjande insatser. Endast ett fåtal studier finns redovisade vad gäller prevalensen av karies, gingivit och dental fluoros bland barn i Tanzania.Syfte: Syftet var att kartlägga antal tänder samt förekomst av karies, gingivit, dental fluoros samt munhygienvanor bland barn i Nkinga English Medium School och Nkinga Public School i Nkinga, Tanzania.Metod: Studien är en epidemiologisk tvärsnittstudie och bestod av klinisk undersökning av 244 skolbarn på 2 olika skolor. Undersökningen avslutades med tre muntliga frågor om munhygienvanor.

A study was carried in conjunction with the Orthodontic department at Halmstad General Hospital in Sweden to investigate the possibility of reducing cost and manufacture time of dental implant drill guides. The current system involves sending a digital image in STL format to the Materialise factory in Belgium where information of the position of dental implants is translated onto a moulded mouthpiece. Drill guides are placed in the mouth piece which is then returned to the surgeon. The mouthpiece complete with drill guides is then placed in the patients mouth and used as a guide for the implant drill holes. The cost of 10000 sek and a turnaround time of 2 weeks gave rise to the need for a faster and cheaper solution.

 Introduktion: Tandlöshet är ett problem som drabbar många människor. Kraven på funktionella och snygga tänder i livets alla skeden har blivit tydligare på senare år. Dentala implantat är en möjlighet att ersätta förlorade tänder och har hjälpt många individer att få sin livskvalité tillbaka.Syfte: Att kartlägga mjukvävnads- och hårdvävnadskomplikationer som kan uppkomma efter en behandling med dentalt implantat och vilka orsaker det finns till dessa.Frågeställningar: Vad finns det för mjukvävnads- och hårdvävnadskomplikationer som kan uppkomma efter en behandling med dentalt implantat?Vad finns det för orsaker till komplikationer efter behandling med dentalt implantat?Metod: Studien är en systematisk litteraturstudie.Resultat: Efter behandling med dentalt implantat kan olika mjukvävnads- och hårdvävnadskomplikationer uppstå. De två vanligaste mjukvävnadskomplikationer var peri-implantär mukosit och mukosal hyperplasi.

Dental implants that are integrated into the jaw bones are widely used to replace lost teeth in human beings. Tooth-loss is often related to loss of the surrounding alveolar bone. This can make implant placement difficult and a bone substituting material may be required. The standard method is to use a bone graft harvested from the patient which requires additional surgery than that needed for implant placement. Limitations in the amount of bone that can be harvested also pose a problem.

Background: Traditional oral health education is seldom enough in order for dental care personnel to motivate their patients to good, long-lasting oral health care habits and there is a need for evaluation of other more efficient methods. One of these methods is motivational interviewing. An overview of its origin, definition, theoretical background and practical methods is given by way of introduction. Aim: The aim of the investigation was to review studies that had used motivational interviewing in order to obtain oral health, focusing on prevention and treatment of gingivitis, periodontitis and dental caries. Method: Systematic review. A search question was run through the databases ASSIA, ERIC, PsycINFO, Social Services Abstracts, Sociological Abstracts and PubMed. The articles were reviewed based on defined inclusion and exclusion criteria. Results: Five publications (based on three studies) met the inclusion criteria.

Rosenlunds sandbankar är ett naturskyddsområde mellan Jönköping och Huskvarna som rasar med ungefär 30 cm per år. Platsen tillåts att årligen krympa men inte att användas. Det görs inga större ansatser för att dokumentera den för framtida generationer eller synliggöra den för nu levande generationer.I detta examensarbete undersöks ett naturligt fenomen som kommer att påverka civilisationer i tusentals år. Examensarbetet syftar i första hand till att återintroducera en bortglömd plats och beskriva hur den förändras i tid och rum. Med hjälp av studier om erosion, landhöjning, istid och med hjälp av fältstudier tolkas platsens förgänglighet i fotografier och i en serie ritningar.Därefter föreslås ett promenadstråk där det direkt går att beskåda de geologiska processer som omformar platsen.

Regulation of rivers by dams and reservoirs is a good example where anthropogenic impact could be considerable both in the local environment, but also has major implications upstream and downstream. This study was accomplished as a literature study of the river Nile, which is extremely important for water supply. The purpose of this study was to investigate the consequences of the construction of the Aswan High Dam, to obtain a consistent flow for water supply, irrigation and power generation in Egypt. Since Egypt has a very hot and dry climate large amounts of water in reservoir is lost to the Nubian aquifer system and by evaporation. The consequences from constructing the dam are considerable.

Claw health has been recorded by claw trimmers at trimming in Sweden since 1996, but data was then captured at each AI association. From 2003 data was captured by central scanning and entered directly to the national cow data base at the Swedish Dairy Association (SDA). This reporting was introduced because SDA wanted to be able to use these records to improve dairy cow claw health by breeding. It is desirable with cows that have healthy claws, because poor claw health can contribute to impaired production and fertility. The claw health report begins with some information about herd, claw trimmer, date et cetera and continues with the part where the claw health is recorded. Here the ID of each cow is filled in and on the same row the conditions for dermatitis, heel horn erosion, sole haemorrhage and sole ulcer are recorded as no lesion (blank), slight lesion (/) or severe lesion (X).

The aim of this study was to describe non-surgical treatment options for the diseases mucositis and peri-implantitis found in present literature. The literature review also illustrates the effect of the treatment opptions on soft tissue with mucositis and peri-implantitis surrounding dental implants. The study reviews twelve scientific articles that have been processed from the aim of the study. The result shows six therapy options, Er:YAG laser, air abrasive, ultrasonic device, hand instruments, hand instruments in combination with antibiotics and hand instruments in combination with clorhexidin. The following methods are described according to how they are used and how they affect the soft tissue surrounding dental implants.

Syftet: Målet med studien var att utvädera kliniska intraorala foton som diagnostisk metod för att bedöma tandslitage (attrition, erosion och abrasion) och jämföra dessa bedömningar med kliniska registreringar. Material och metod: Studien genomfördes på Tandvårdskolan i Malmö, där man slumpmässigt valde ut 30 vuxna patienter. Dessa patienter undersöktes med avseende på tandslitage (attrition, erosion och abrasion) och kliniska foton togs. En månad efter kliniska registreringen gjordes en bedömning av de kliniska fotona, utan att ha kännedom om resultatet av de kliniska registreringarna. Båda undersökarna har på samtliga patienter utfört klinisk registrering och fotobedömning oberoende av varandra. Intra- och interobservatör överensstämmelse uppskattades genom Cohen?s Kappa- koefficient. Resultatet: Intraobservatör överensstämmelsen mellan bedömningar av foton och kliniska registreringar var måttligt-till-god med ett P-värde på 0,039-0,046.
