Är framtidens avtryck digitala? En jämförande litteraturstudie mellan konventionell och digital avtrycksteknik

Syfte: att sammanställa vad som finns publicerat om digital avtrycksteknik och jämföra denna teknik med konventionell avtrycksteknik för fast kron- och broprotetik och på så sätt underlätta för operatörer att välja metod. Material och metod: litteratursökningar gjordes via Pubmed, Science Direct och genom handsökning i International Journal of Computerized Dentistry och Quintessence International. Informationssökningar gjordes även via fabrikörernas hemsidor och i litteratur vid Malmö Högskolas Odontologiska bibliotek. Resultat: det finns ett fåtal publikationer, varav de flesta är in vitro studier. De gav underlag för en jämförande diskussion av följande punkter: tidseffektivitet och användarvänlighet, precision och passform, kostnad, miljövänlighet samt patientvänlighet. Konklusion: denna litteraturstudie visar att på grundval av de publikationer som finns idag så fungerar den digitala avtryckstekniken tillfredsställande och fullt jämförbart med konventionell teknik för fast kron- och broprotetik. Det finns idag vissa belägg för att digitala tekniker kan ersätta den konventionella vad gäller precision. Det bör dock påpekas att de studier som finns tillgängliga idag är in vitro och dessa behöver kompletteras med och verifieras genom kliniska studier..

Att reducera ledtiden i en produktion med hög variation och låg volym - En casestudie på Lab.gruppen

Due to increasing product availability and higher demands on fast deliveries, the competition between companies is growing. To be able to satisfy the customers? requests an efficient logistics system with short throughput time is required. By using tools associated with Lean production companies are able to make great improvements in their manufacturing systems and reduce lead times to satisfy customer demands.There are two classifications associated with manufacturing, high variety and low volume (HVLV) and low volume and high variety (LVHV). The general belief is that the concept of Lean production is difficult to implement in a production environment with high variety and low volume due to the concept being adapted to mass production.

Grafiskt gränssnitt till databas med val- och delfinljud

Företaget Duroc Engineering AB tillverkar lasersvetsade produkter till flertalet olika industrier. Lasersvetsningen innefattar främst lasercladding, vilket är en metod där maskinen svetsar på ett ytskikt av metall på en befintlig metallbas. I denna process smälter en laserstråle ett finkornigt metallpulver, som sedan sprutas in i processområdet med argongas.De flesta produkter som företaget lasersvetsar är av axeltyp, därför använder laseroperatören en rotationsenhet i vilket axelmaterialet spänns upp i. På andra sidan av rotationsenheten har lasermaskinen en dubbdocka, detta för att stötta upp axeln likt en konventionell svarv.Duroc använder idag en fast rotationsenhet som bultas fast i golvet, vilket har ett nät av precisionsborrade hål. Processen med att ställa in dubbdockan för olika längder av axlar är tidsödande och kräver många justeringar innan axeln slutat kasta.Examensarbetet baseras på att utveckla en dubbdocka med längdjustering i z-led likt det som används i en vanlig svarv.

Klassning av renbete med hjälp av ståndortsboniteringens vegetationstypsindelning :

During thousands of years, reindeer have adapted to living under harsh conditions with large seasonal variations in climate and forage availability. This adaptation implies that body functions and nourishment needs are strongly bound to the season. In the summer the reindeer has to maximize food intake to build up fat and protein reserves for the winter. More than 200 different plant species are included in the reindeer diet, but since reindeer have an unique ability to use the nourishment in lichen, different lichen species make up a large portion of their winter diet in many areas. Fundamental for reindeer husbandry is access to natural grazing during most of the year.

Utveckling av metod för retrospektiv bestämning av absorberad dos i korall medelst elektronspinnresonans

This diploma work was performed at the department for radiation physics at the Health University in Linköping. Its aim was to develop a method to retrospectively quantify the absorbed dose in coral. Coral is a material which suites well as a retrospective dosimeter because when exposed to radioactivity its induced free radicals are stable in time. The number of radicals is proportional to the accumulated dose so the dose can be calculated by quantifying the radicals. Therefore, coral can tell us something about the past environment and also be used in dating purposes.A young, modern coral from the Red Sea was studied and also a fossil one which I was given from the Natural History Museum in Stockholm.

Concentration and offtake of trace elements and macronutrients in Italian ryegrass (Lolium multiflorum Lam.) and spring barley (Hordeum vulgare L.) grown on soils amended with water treatment residual sludge

Aluminium sulphate (Al2(SO4)3) is usually added during the drinking water treatment processin order to precipitate organic and inorganic material, resulting in aluminium-based drinkingwater treatment residual sludge (WTR). Since 2003 Swedish law no longer permits WTR tobe deposited in lakes, and there is an interest to explore the possibility to utilize WTR as soilamendment. The aim of this study was to examine the effects of WTR application on cropgrowth and concentrations of macronutrients and trace elements (including micronutrients andpotential toxic elements). A greenhouse pot experiment was conducted with three soils; a clayloam rich in phosphorous (P), a loamy sand rich in P, and a silty loam with a low soil Pconcentration, and two crop species Italian ryegrass (Lolium multiflorum Lam. cv.

Inventory and evaluation of Nairobi Animal Orphanage : focusing on spotted hyena, serval, Sykes' monkey, vervet monkey and on educational elements

The present BSc thesis is part of a newly established collaboration between the Swedish zoo Skansen and Kenya Wildlife Service (KWS), and constitutes of an inventory of the Nairobi Animal Orphanage (AO). As a refuge for wild animals found orphaned, abandoned or injured throughout Kenya, the AO has grown over the years and reached an unsustainable point where external help is needed for solutions and improvements. The aim of the inventory is to specifically consider the husbandry and enclosures of spotted hyena (Crocuta crocuta), serval (Felis serval), Sykes? monkey (Cercopithecus albogularis) and vervet monkey (Chlorocebus aethiops) and with the aid of facts about the species, estimate how well their biological needs are satisfied. Different educational elements are also reviewed since one of the main purposes of the AO is for education.

Fire impact in the wood quality and a fertilization experiment in Eucalyptus plantations in Guangxi, southern China

Chinas government has a multifunctional program for a more sustainable forestry since 2000. This six key forest programs goal is to develop a more sustainable forest sector but also take environment consideration. The state forest administration in China has decided to create 5.8 million hectare of fast growing and high yield forest. Eucalyptus has showed to have good properties for pulp and timber production and therefore Eucalyptus plantations are under development in costal areas in southern China. By adding extra nutrients, growth can be enhanced in Eucalyptus plantations.

Kvalitet i brödvete :

The quality of bread wheat is a large subject to study. The quality rests on two legs. The first one is the inheritance of specific characters, which can be influenced through plant breeding and type of cultivar. The other one is the environmental influences, such as crop rotation, nutrition, harvest and storage. The latter factors are possibly to affect through cultivation practices, while other factors are not possible to influence on for the grower, such as seasonal changes of weather and the soil content.

Skillnaden i perception mellan hockeyspelare på professionell kontra icke professionell nivå

Purpose: The purposes of the current study were to investigate whether there were any differences in the perceptual ability between professional and non-professional ice-hockey players and whether professional players are better at distinguishing, paying attention to and concentrating on what is important during intense physical activity. Method: Twenty male ice-hockey players (10 from both the Swedish first and third divisions) participated in the study. Wingate test were used for physiological measurements while three psychological tests were presented in front of the participants. Stroop, Flanker and Fast counting tests were used to measure perceptual and coping abilities during intense physical activity and the differences between the two groups. Results: Fast counting and Flanker word 2 tests showed a significant difference between the two groups, whereby the professional groups was faster and more accurate than the non-professional group in answering.

Vallfoder till slaktgrisar : effekter på tillväxt och social beteende vid utfodring

The aims with the project were to investigate how forage consumption affect production and pigs behaviour around the feeding. This degree project was designed to follow 48 growing/finishing Hampshire*Yorkshire pigs, from 30-110 kg live weight, fed diets with or without 20 % forage inclusion. The pigs were divided in three groups due to dietary treatment. In the first group the pigs were fed 20 % of the energy in the feed ration by long grass/clover silage (LE) and the remaining 80 % by a cereal concentrate. Group two was fed chopped grass/clover silage mixed with cereal concentrate (HE) in the same amounts as LE.

Monitoring and pest control of Fruit flies in Thailand : new knowledge for integrated pest management

Fruit flies (Tephritidae) are serious pests that cause enormous losses for farmers in many countries. The frequent use of insecticides in controlling fruit flies in fruits and vegetable has not resulted in sustainable management of the pest. Problems associated with this complete reliance on chemical control are many residues of insecticides in crops, health problems for farmers, contamination of water and soil, insecticide resistance development and decrease in natural enemy populations. The implementation of control measures that do not imply an added burden to the environment and/or the farmers is urgent. More knowledge about the ecology of fruit flies is the basis for finding new and better ways to control this pest.
