Är förekomst av knäckesjuka i tallföryngringar mindre på stora naturvårdsaspar än på aspsly?
Pine twisting rust (Melampsora pinitorqua) is a parasitic rust fungus found all across Sweden causing damage resulting in lower quality and reduced tree growth in pine stands. In Sweden, the fungus is dependent on two alternate hosts; European aspen (Populus tremula) and Scots pine (Pinus sylvestris). Pine twisting rust has five different spore stages, two of them (uredinio- and teliospores) on the leaves of aspen. Injures on aspen caused by pine twisting rust is not extensive. On the other hand, when it infects the annual shoots of Scots pine it often results in a bent steam or even a top shoot breakage.
Reglering av matarsystem vid höghastighetskapning
Today small metal parts are mass-produced as for example rollers in cylinder bearings. At high velocity cutting the metal is cut with a great force in a scissor-like device. Both precision and repeatability is important to be able to guarantee good quality, but from an economical point of view it is also important to keep a great manufacturing capacity. The part of the process that is most time consuming is when the metal bar, that is about to be cut, is fed to the right position. Therefore it is interesting to examine if the time used for positioning can be reduced.
Äldres delaktighet : Om delaktighetens betydelse för individer i socialtjänstens handläggningsprocess
In Peter Weiss debut Fra?n o? till o? (1947) the ?I? travels from island to island as a castaway. The island here can signify, or work as a synecdoche for exile and the feeling of isolation that exile often induces. But the movement from island to island also implies a restless state: Peter Weiss shifting from painting to writing to filmmaking and theatre, from German to Swedish and then back to German. The years during exile and the years that followed the exile until his breakthrough in Germany with Schatten des ko?rpers des Ku?tchens (1960), Abschied von den Eltern (1961) and Fluchtpunkt (1962), were the formative years of Peter Weiss authorship.
RoDent : Robotic Dentistry : Computer aided dental implant positioning system
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.
Just In Time : Effektivisering av materialflöden med hjälp av principer från Inventory Management och Production Management
AbstractManagement is a field that started getting attention in the beginning of the 20th century by Frederick Taylor. His publication is called the Principles of Scientific Management and is based on the principles of using scientific methods to find the best way of conducting each operation within a production facility. Many of Taylor?s principles may appear obsolete today but the matter of an effective material flow is still highly current. Efficiency is the relationship between the input into an operation and its result.
Optimering av ritningsarbete
När ett haveri inträffar uppstår direkt en mängd olika kostnader i form av underhållsinsatser, reparationsmaterial och administrationsinsatser. Utöver dessa kostnader förloras även de intäkter som maskinen genererar samt täckningen för de fasta och rörliga kostnaderna. Alla dessa kostnader skall täckas av de värdeskapande enheterna på företaget och påverkar det finansiella resultatet negativt. För att förbättra ett företags lönsamhet ökas antingen intäkterna eller så reduceras kostnaderna. Trots detta är det för många företag okänt hur stor kostnaden faktiskt är då en maskin står stilla.Arbetets uppdragsgivare är Konecranes Machine Tool Service (MTS), ett företag som erbjuder underhållstjänster och underhållslösningar till företag inom verkstadsindustrin.
Energikartläggning hos RostiGP i Gislaved
In today?s modern age, energy consumption has become a major issue, both from an environmental viewpoint and cost perspective. Because of a rapid technologic change and increased costs of production of electricity, the demand to develop effective methods for energy efficiency industries have grown.The electricity-intensive industries, such as plastic industry, the demand to reduce energy consumption has grown significantly over the past 10 years, which have led to the development of different methods to determine and locate energy-consuming parts in the industry. This also means being able to prioritize and organize activities in the industry.In this study the measurements of voltage, current, power and PF performance on injection molding machines (K-TEC 275 form Ferromatik Milacron in Germany) with a focus to locate, within a machine, various measures that could improve energy use in the plastics industry, in this case RostiGP in Gislaved. These measurements have been carried out with the help of a power quality clamp meter to carry out time logs of the machines for some time during normal word rate.
Omvärlden påverkar : En studie av hur revisionsbyråernas marknadsföring har påverkats av den avskaffade revisionsplikten för mindre och medelstora företag.
Titel: Omvärlden påverkar: En studie av hur revisionsbyråernas marknadsföring har påverkats av den avskaffade revisionsplikten för mindre och medelstora företag.Nivå: Kandidatuppsats i företagsekonomi; MarknadsföringFörfattare: Reine Haddad och Louise MattssonHandledare: Jonas KågströmDatum: 2012- JuniSyfte: Med uppsatsen vill vi undersöka om revisionsbyråernas marknadsföring förändrats i samband med att revisionsplikten för mindre bolag avskaffats, det vill säga om marknadsföringen påverkas av omvärldsfaktorer.Metod: I studien används en abduktiv ansats där information samlats in dels via Internet (WayBack Machine) och dels genom att ta del av annonser från en revisionsbyrå. För att tydliggöra materialet sammanställdes det i frekvenstabeller, wordles och diagram.Resultat & Slutsats: I enlighet med vad den valda teorin framställer ser vi att även revisionsbyråerna ändrar delar av sin marknadsföring när förändringar i omvärlden sker. Omfattningen av förändringarnas påverkan på marknadsföringen varierar från revisionsbyrå till revisionsbyrå, bland annat beroende på revisionsbyråernas syn på marknadsföring, hur stora förändringarna i omvärlden är och hur snabbt revisionsbyråerna tar till sig dessa förändringar.Uppsatsens bidrag: Vårt examensarbete har bidragit med att ge en bild av hur revisionsbyråernas marknadsföring påverkas av förändringar i omvärldsfaktorer. Detta kan vara användbart då marknadsföraren måste ta dessa omvärldsfaktorer i akt vid planering och utformning av marknadsföringen.Nyckelord: Revisionsplikt, revisionsbyrå, marknadsföring, påverkan och omvärldsfaktorer..
Undervegetation : användning av vedartade marktäckare i anläggning
The use of the robust and durable woody ground covers is increasing, not in the least in public places. The group includes low shrubs of different height that effectively build low, tight vegetation that covers the ground. Despite all the good qualities the knowledge about them is quite low and there are ideas about them of being dull.
The woody ground covers manage to struggle against weeds effectively by competing for nourishment and water, but above all, by the canopy of the ground covers that prevent the weeds from getting enough light. In that way the woody groundcovers can effectively compete with the annual weeds.
Utvärdering av en subjektiv metod för att skatta mängden trädbiomassa längs vägkanter :
Forest biomass is becoming an increasingly important source of renewable energy, and thereby the demand is increasing. There is currently 213 000 km of forest roads in Sweden that could be suitable for biomass harvesting. Harvest of biomass along forest roads both provides biomass and maintains the quality of the roads. Currently, the volume of biomass along roads can only be assessed post harvest, chipping and industry deliverance.
As the decision of whether or not to harvest should preferably be based on more than experience, the TJ-method has been proposed. The TJ-method is a subjective method to quickly determine the dry matter quantity with the assessment being conducted from the roadside.
Konstruktion av testrigg för moderna ångexpandrar
This report summarize what have been done during the Master of Science Thesis that Klas Schjelderup has written for the company RANOTOR Utvecklings AB. The company is developing modern steam engines and this work should develop a machine to perform tests on a new type of piston seal that hopefully could be used in the future. The steam engines will be both volumetric and energy compact, around 1600hp/literof cylinder volume, and it will have a lot of practical applications.The new type of piston seal is hydrostatic lubricated which means that a fluid is separating two faces that normally is in contact. In this case pressurized water is used to separate the piston seal from the cylinder wall. RANOTOR have earlier formulated that at least the expander in the modern steam engine have to be oil-free, due to other components functionality in the closed water system.
Ny teknik för kombisådd :
The use of combi-drilling during spring tillage has become very common in southern
Sweden in recent years. Combi-drilling leads to fewer passes on the field and better plant
nutrient utilisation. An example of a combi-drill is the Väderstad Rapid, which is very
widely used in spring tillage in southern Sweden. The Rapid has separate fertiliser and
seed coulters, which means that the draught requirement is relatively high. It thus
requires large, heavy tractors, which compact the soil and are comparatively expensive to
buy and run.
A few years ago the Finnish combi-drill Tume Nova Combi came onto the Swedish
market.
Eftermarknadens möjligheter : En studie av Swecon AB:s tjänsteutbud
ProblemThe manufacturing industry is a mature industry where the profit margins are small and the competition is hard. This makes it hard for both manufacturers and resellers to gain market shares and reach reasonable profit margins only by selling products. Therefore Swecon who is reseller for Volvo Construction Equipment tries to find alternative methods and ways to increase their profit. An alternative source of income could be to develop the range of services that are connected to the ground products.PurposeThe purpose of the thesis is to examine how Swecon in southern Sweden can improve their offers of existing services connected to the ground product and investigate the demand of new such services.MethodThis study is based on a qualitative study of five of Swecons local offices and five of Swecons customers. The empirical framework is mostly based on personal interviews but in some cases information was retrieved by using phone interviews.
Energieffektivisering genom förvärmning av flis till kokare med sekundärvärme
The Swedish pulp and paper industry meets higher demand for energy efficiencyi mprovements with increasing energy prices and changes in the Swedish renewable energy certificate system. One action of energy efficiency improvement is by using secondary heat, that otherwise would have been treated as waste heat, for use in a system with lower temperature demands. The aim of this Master´s thesis is to identify possible secondary heat sources in a typical Swedish pulp and paper mill and to investigate what economic benefits the secondary heat will provide when being used for pre heating of wood chips to a kraft digester.The Master´s thesis focuses on three secondary heat sources; dry warm air, warm water and moisture saturated warm air located inside the pulp or paper mill. Two types of kraft digesters are simulated within this study, a typical Scandinavian digester and a modern twin vessel steam phase digester.Due to quality aspects and low temperature level drying is the drying technology with dry warm air rejected. Using warm water in direct contact with wood chips increases the quantity of water to the evaporation plant and thus reduced pulp or paper production and is therefore also rejected.
