Earlier investigations showed that damages on timber from feeding rolls could be within the lower classes of damage according to VMRs classes. Knowledge about differences in productivity between kind types and aggressive types of feeding rolls is necessary because it should influence the question about damages on timber caused by different feeding rolls. In this study the production and timber damage in a harvesting head were evaluated at three levels of pressure (8, 10 and 14 MPa) on the feeding rolls, and with three different types of rolls. One type, the rubber cushioned steel plate roller had 10 mm studs and rubber damping, one ?middle? type made of solid steel with 14 mm studs, and one aggressive type, also made of solid steel with 18 mm studs.

Which lignoses are suitable for childrens enviroment? There are many aspects to consider when establishment on schoolyards and playgrounds..

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.

Sammanfattning Tandslitage är ett vanligt förekommande problem. Det finns olika typer av tandslitage såsom attrition(fysiologisk), erosion(kemisk) och Abrasion(mekanisk). De bakomliggande orsaksfaktorerna skiljer sig åt för de olika typerna av tandslitage. Attritioner delas upp i normalt och patologiskt. Normalt tandslitage beror på ålder och kost, medan patologiskt tandslitage som även kallas bruxism, kan orsakas av stress och oro.

Många faktorer påverkar den orala hälsan, däribland kosten. Idag finns många olika kosttyper samt livsstilar, och något som ökar i Sverige är den vegetariska kosthållningen. Syftet med denna litteraturstudie är därför att kartlägga vilken inverkan vegetarisk kost har på den orala hälsan. Artiklarna som användes i denna litteraturstudie hämtades från databasen PubMed, och studiernas referenslistor granskades kritiskt. Det upptäcktes också artiklar genom referenslistgranskningen.

Rapporten innefattar en jämförande studie mellan olika typer av membran och beläggningar.Främst sker en jämförelse mellan materialens förmåga att andas. Vattentäthet testas på nyamaterial och efter olika sorters nötning så som martindale, flexing och tvätt för att få en ökadförståelse för materialen. Verktyget som används i studien för att mätaånggenomsläppligheten är hudmodellen. Resultatet presenteras med ett Ret-värde vilket är enförkortning på Evaporative resistance of a textile. Metoden används för att på ett bra sättsimulera hur huden svettas.Projektet har utförts på Swerea IVF som är ett forskningsinstitut beläget i Mölndal.Hudmodellen är en av de senaste stora investeringarna på Swereas textil och plast avdelning.Resultatet av studien visar att laminat andas bättre än beläggningar, dock har bärarmaterialetstor inverkan på resultaten.

Dooria Sweden AB is one of the main door- and doorframe manufacturers inSweden. They deliver door frames for indoor use for project oriented buildingsites, for these types of building sites the doorpost comes pre-assembled. DooriaAB wants to minimize transport to reduce impact on environment and thetransportation costs of pre-assembled doorframes, this thru simplifying themethod of assembly.The main purpose of this thesis has been to develop a prototype solution thatbrings the three parts of the doorframe together with the same properties regardingstability and tightness of joints as the current method of assembly. A profile ofdemands and wishes were created in collaboration with Mårten Dragstedt, DeputyDirector of Dooria Sverige ABBy following the chosen method the authors have been able to produce a fullyfunctional prototype that meet the demands that were put on the product. Catia V5R20 has been used as an aid during prototype construction and virtual tests.

The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and Abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.

Judged by appearance. This is the conclusion of research made on shopper behavior that revealed that consumers tend to go by their instinct when evaluating vacuum cleaners in a purchasing situation. Many buy the first vacuum cleaner they interact with and few buy pre-planned brands. Almost none even turn the machine on before taking a purchase decision.Electrolux Floor Care Europe has their factory for vacuum cleaners in Hungary. Increased competition from China makes it harder to "only" produce vacuum cleaners with good performance.

A pavement construction designed to cope with the different type of traffic loads; it is exposed to and at the same time it can resist the effect of the climate. A road structure consists of sub- and superstructure which is divided by a boundary known as terrace. During the construction of unbound layers (base course and sub-base course) in the superstructure, it is always ensured that the material meet the requirements for bearing capacity and the degree of compaction. These parameters are controlled by various laboratory tests and control methods. To obtain increased knowledge of the material and improve the quality of the compaction in the field, it is necessary to perform laboratory tests in order to determine material properties.A base course material 0/ 32 mm limestone from Gotland (Hejdeby) was investigated in this study.
