I have chosen to work with drag hose system and try to find an alternative to spread manure with a usually tank system, see if you can make a profit and what advantage and disadvantage the system has. The purpose whith the project has been to try to make a system that can spread manure at better occasions than farmers do today and above everything make a financial addition. Today it is just a heavy work and takes a lot of time. I have counted on investment costs and carefully examined what equipment you need. I have not the technical details in my project, I have just tried to understand how it is to spread manure with drag hose system today. What is drag hose system? You put a hose in your manuretank, connect it to a Pump that is driven by a traktor or stationary engine. You place a hose that reach the field were you are going to spread.

Climate change is the modern society?s common issue. The developed countries areconsuming more than what is sustainable, and the climate change due to the use offossil fuels can be seen clearly. EU has specified goals, in order to stop furtherdamage, which demand that every member state have to reduce its energyconsumption by 20 % before 2020 and 50 % before 2050, relative to 1995.The Swedish government uses a number of instruments to encourage reduction in theusage of energy, but every individual has to contribute to reach the goals.With increasing energy price the cost of living is going up. A lot of people are lookingfor ways to save energy and not be affected as much by the increasing price.Investments for insulation, replacement of windows and replacing old heating systemfor a new efficient heat Pump is getting more and more common.This thesis is about investigating the possibilities in becoming independent from buyingenergy for households.

This report is made as a literature review, focusing on the work done to increase understanding of efficiency in the categories of substations and secondary heating systems, with respect to the deviation from the theoretically possible cooling off in the distribution network as well as the economic benefit that appear. The main purpose of a considerable part of the literature used in this report addresses the issue of identifying individual causes of reduced cooling in district heating systems. These literature resources have been compiled and summarized as part of the report.The technology of district heating is associated with benefits such as better use of the energy in a fuel. This is the case of cogeneration plants where serial generation of electricity and thermal energy increases efficiency compared with the parallel generation where heat is generated locally and electricity is generated centrally. Serial generation thus allows for lower primary energy demand.

In a sustainable society the use of renewable energy and recycling of materials is of high importance. Wastewater treatment plants use large amounts of energy in the processing of wastewater. This study seeks to evaluate wastewater as an energy resource and to examine treatment plants potential to become sustainable energy producers. The study is based upon the internal processes of Himmerfja?rdsverket.

Smärta är ett fenomen som inte bara påverkar patienter fysiskt utan även psykiskt. Kvinnor som genomgått mastektomi upplever att smärta påverkar deras livskvalité. Humörsvängningar, dålig sömn, depression, ångest och rörelsehinder är vanligt förekommande symtom som följd på postoperativ smärta. Syftet: Syftet med denna studie var att belysa vad sjuksköterskan kan ge för olika behandlingar och omvårdnadsåtgärder vid smärta efter mastektomi. Metod: Studien genomfördes som en litteraturstudie där författarna granskade sexton vetenskapliga studier.

I detta exjobb har en testplattform skapats för att kunna testa, utvärdera och jämföra olika Pumpstyrningar i torr miljö. Testplattformen består av en simulerad Pumpstation till vilken befintliga Pumpstyrningar av valfri modell kan kopplas, det vill säga ett Hardware-In-the-Loop-system. De främsta fördelarna med en sådan plattform är flexibilitet, snabb feedback samt möjligheten att återskapa exakt samma förutsättningar för olika Pumpstyrningar.Testplattformen har implementerats i LabVIEW på en PC som kommunicerar med Pumpstyrningshårdvara via ett I/O-kort för analoga och digitala signaler.Det simulerade systemet konfigureras genom val av bland annat Pumpar, Pumpsump, inflöde och rörsystem. Utifrån de inmatade värdena och styrsignaler från Pumpstyrningen simuleras sedan bland annat systemets flöden, energier och temperaturer. Nivån i sumpen, och övriga insignaler till Pumpstyrningen, återkopplas från simuleringen.

Quality assurance for Scania engine componentsScania engines have become one of the world?s most renowned corporations in themanufacturing of engines. This is mostly due to the quality and performance thatScania have shown. However, this does not stop Scania from trying to achieve moresuccess in the fields of development and research to assure the quality of theirengines.The purpose of this thesis is to show how Scania ensures the quality of the enginecomponents, both those who made externally and internally at Scania, also inclusivethe manufacturing and assembly process.Three engine components were examined: D16 block engines, water Pump andXP-Iinjectors. The study included the whole process from the step of supplying therow materials to the last step in production functional test.In this thesis an investigation of how other companies are working with qualityassurance was conducted.

Parasiter i magtarmkanalen och framför allt nematoder, orsakar världsomfattande produktionsförluster hos lantbrukets djur. För att kontrollera nematodinfektioner används anthelmintika. En överanvändning av anthelmintika har resulterat i att vissa nematoder utvecklat resistens. Därför är det väsentligt att vi tillämpar en sund användning av anthelmintika som inte gynnar vidare resistans utveckling. Makrocykliska laktoner är den substansgrupp som används flitigast.

The first part of this essay is about a single-family house that we have planned and projected. Thesecond part is a deeper study in ways to further insulate windows when they are not in use.In the first part the building?s design and its most important construction elements are described.The planning of all major installations (heating, domestic water, ventilation, sanitation, electricity)are reported so that one can in principle start construction of the house. In addition there arecalculations done on the building?s energy management.The result is a two stored house angled toward the south.

This report is a degree project performed at Freudenberg Household Products AB, (FHP). The degree project comprises measurement and analysis of the power net at FHP Basproduction. The content is divided between one theory-part, one document- part with measurements and also conclusions and a list of measures to be taken. During the project the purpose and restriction change from a quality investigation to only concentrate on harmonics and finding the reason why they exist, and also to find a solution to the problem with harmonics. The measurements shows that the power net contains harmonics of different order and intensity.

Transdermal drug delivery, besides painfulinjections with syringes, has long been associatedwith small size particle pharmaceuticals, which candiffuse through the skin. This method of drugadministration has only been applicable on a smallnumber of drugs, where active molecules are smalland delivery time should or can be long.Other drug delivery options are oral administrationand injection with hypodermic needles (ordinaryhospital syringes). In oral administration thestomach and liver tend to dissolve the drug and theeffect becomes more difficult to anticipate, anddrug delivery rates difficult to control. Hypodermicneedles are used as a mean of drug injectiondirectly into the bloodstream. This method ispainful and risks infection due to tissue damageand skin penetration.One way to get a painless non-damaging techniquewith high delivery rate that still can delivery largemolecules is to manufacture an array of microscopichollow needles and equip them with a Pumping unitthat delivers the correct amount of drugs.This thesis shows the technique and possibility ofmanufacture micromachined needles using low costtechniques of Ion Track Technology (radiation ofheavy ions creates porous materials), electrolessdeposition (non-current activated wet chemistrymethod of depositing metal) and electroplating.

För att tillgodose den studerande KTH byggnadens framtida krav kommer det befintliga ventilationssystemet att bytas ut. Två olika möjliga värmeåtervinningssystem har jämförts ur fjärrvärmebehovssynpunkt. Det befintliga systemet med vattenburen batterivärmeväxlare har en låg värmeåtervinningsgrad och Akademiska Hus önskar system med högre värmeåtervinning. I byggnaden har roterande värmeväxlare och frånluftsvärmePump för uppvärmning av tilluften jämförts. Då värmeåtervinning från dessa system inte är tillräckligt kommer fjärrvärme att används.I beräkningarna jämförs fem roterande värmeväxlare mot varierande antal frånluftsvärmePumpen.

In recent years, existing solutions for cooling personal computer CPUs have been supplemented by a new product category, factory sealed water cooling loops. These systems, consisting of a water block with an integrated Pump, a fan and a radiator, perform well compared to the air cooling solutions but are less effective than larger, custom-built water cooling systems.This project aims to explore the most important aspects of a factory sealed system and to identify possible cost-effective enhancements of the performance.The most significant differences between the different groups of water cooling loops are the block design and the Pumping power. The performance of both categories is also largely dependent on the fan power, but increasing fan power has a large negative impact on the noise level.Both radiator size and fan model choice appear, in tests, to be relatively unimportant, presuming that the noise level is kept constant. The position and direction of the fan, however, has significant impact on both the temperature and the sound level.Water blocks can be designed in several different ways, both regarding the heatsink design and the flow direction. In simulation, flow with the inlet centered above the heatsink result in considerably lower pressure drop and slightly higher temperatures than flow through the block, for heatsinks with fin arrays.Creating a competitive product in this product segment certainly seems possible, as there are performance-increasing changes to be made that seemingly has little impact on the production cost.

Med ett växande energibehov och större efterfrågan på grön kraft blir sökandet efter hållbar energi av allt större intresse i det moderna samhället. Solkraft är en av alla lösningar. Även om solkraft som huvudenergikälla inte är en praktisk lösning i Sverige, eftersom Sveriges energibehov är som störst under vintern, kan solkraft på liten nivå användas som komplement. I denna rapport tas därför en teoretisk modell fram för småskalig solenergiproduktion.I förstudien har både termiska och fotogalvaniska detektorer undersökts och de reflektorformer som har studerats är paraboliska halvrör och paraboliska diskar.För att få en uppfattning om hur effektiv solfångaren är har överslagsberäkningar genomförts.Modellen som projektet har resulterat i är en hybrid solfångare av typ paraboliskt halvrör. Detektorn är ett vakuumisolerat u-rör i koppar.
