A possible way to reduce pollution and slow down the process of global warming is to increase the usage of renewable energy sources. One of these renewable energy sources is solar power. With the aid of solar panels and solar cells the energy from the sun can be transformed into both heating and electricity. The requirement to use the sun in this fashion is a suitable surface, for example a big roof, an angle between 40-60 degrees and that the surface should be exposed to the south. Almost every farm meets these requirements.

The aim of this study was to develop a simple model for calculating stock costs for bio fuel at Billerud Karlsborg and subsequently recommending a suitable stock level of bio fuel. The stock components considered in the model are GROT (branches and tops), bark, dry wood chips, raw wood chips from barking and sawdust. The calculations are based on a probability distribution of historical deviations between ordered and delivered volumes. The model presents two different ways to manage the supply in case of irregular deliveries. The first way is to stock enough volume to cover the deviations and the second way is to compensate with a quick purchase from the spot market (at extra high purchase prices).

The purpose of this study was to evaluate meals and eating in one day for at least ten truck or lorry drivers. Another aim was to investigate the attitudes by the drivers to food and meals and their expectations on the meals. This is a qualitative study conducted in ten interviews, seven of which were over the phone. The interviews were semi-structured and took about twenty minutes for each driver. Data relating to the food choices for one day were collected and questions asked about their attitudes to food and meals were collected simultaneously.

The aim of the study was to examine both 1) how aware teachers in a specific area are about ICT tools in teaching ; and 2) how likely teachers are to use ICT tools to reverse the trend of unmotivated students and low achievement scores . I will look for answers through the following questions:How extensive is the knowledge of the teachers on digital and social media in education? How have teachers in the past year used various social media in their teaching? In what grade does ICT-supported teaching lead to higher motivation, participation and achievement? Is there a difference between the sexes, different stages (1-3, 4-6, 7-9) and number of years in the profession in knowledge of and openness to the use of ICT in education?The method used is a questionnaire in which a number of respondents have answered a number of questions about ICT tools in teaching. Validity of the study can be said to be high when the survey has measured what it intended to measure, however, I need to be careful in draw full account of the result as the response rate is low with only 39%. In summary, the results show that there is low awareness among respondents about the methods and the digital and social tools I lift in the survey.Mainly the respondents use some of the methods and the digital and social tools in preparation for the lesson.

Want to help making the world a better place? Do it with HypOCycle!HypOCycle is a bachelor thesis that started in September 2007. The project is owned byLars-Johan Hjertz and Erik Westerlund.HypOCycle is probably the only bike in the world that has a linear pedal movement. Themovement comes from a new engine technique that hasn?t even been brought to themarket yet.

Under det senaste årtiondet har 97 % av den totala folkökningen tillkommit inom fem kilometer från kusten, främst kring storstadsregionerna. Tyresö kommun är en av Stockholms förorter. Kommunen har under åren köpt loss tomter i ett kustnära område vid Tyresö strand. Ekologigruppen ab har på uppdrag av kommunen gjort bedömningar av områdets naturvärden såväl som rekreativa värden. Bedömningarna är tänkta att kunna vila som beslutsunderlag för planering såväl som byggnationer i området.

Background and problem: The background to this study is the organizations increased difficulty to retain employees in the organization when more and more employees today choose to do their career in several organizations. The problem to keep the employees in the organization leads to several problems where the loss of experience reduces efficiency and increased risks and cost associated with recruitment are some problems that arise. The problem therefore faced for this study is: How can opportunities for career development within an organization created to get employees to stay over time?Purpose and method: The purpose for this study is to describe how organizations can create opportunities for the development of career that gets employees to stay within the same organization and make their career in this organization. The method used for this study is a qualitative approach where data is collected through semi-structured interviews in a case study.Empiricism: The empirical result have shown there are four factors that an organization should overhaul to create an opportunity for the development of a career that gets employees to stay in an organization over time.

Biogas mainly consists of methane and carbon dioxide, where methane is theenergy-rich gas, and is naturally created when organic matter breaks down in absenceof oxygen, also known as anaerobic digestion. A biogas plant re-creates the anaerobicconditions inside a digester where the organic substrate is fed into and digests toproduce biogas. The gas is then used to produce energy by combustion and can beseen as a completely renewable fuel.Today, energy from biogas is used primarily by major stakeholders such asmunicipalities and thus the plants become very large with high investment- andconstruction costs. There are currently few small plants in Sweden, even though thepotential for agriculture and medium-sized to smaller farms to become self-sufficientin terms of electricity and heat is great. Farms have a natural stock of digestibleorganic material in form of manure or crops for example, which are constantlyavailable.

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.

Organic agriculture is financially promoted in Sweden by special environmental support and as consumers we are all encouraged to buy organic food. At the same time scholars at the Swedish University of Agricultural Sciences claim that organic farming does not provide any environmental benefits. The main criticism is that organic farming has lower yields than conventional, which means that more land is needed to produce the same amount of food as in conventional farming, leading to deforestation and loss of biodiversity. As for climate change, the critics claim that the significantly higher productivity in conventional crop production compared to organic, releases surplus land, which could be used for bio-fuel production and thereby replace the fossil fuels. The critics also claim that organic farming causes higher nutrient leaching than conventional.

Bakgrund: Kronisk sorg är en icke- patologisk, känslomässig sorg-reaktion relaterad till förluster som uppfyller den sörjandes liv. Att leva med en kronisk sjukdom innebär många förluster som kan göra det svårt att hantera situationen, särskild om sjukdomens progressivitet innebär nya förluster för patienten. Brist på kunskap om kronisk sorg kan medföra att patienter får behandling mot depression men ingen hjälp till att hantera sorgen. Syfte: Syftet är att beskriva patienters upplevelser av kronisk sorg till följd av kronisk sjukdom. Metoden: En systematisk litteraturstudie på vetenskapligt kvalitativt material gjordes med den enligt Evans beskrivna analysmetod på kvalitativ data.  Resultat: Fyra teman framkom: emotionella förluster, kroppen sviker, förlorad framtid och lindrad sorg.

Mankind faces a serious threat. Its activities, for example the burning of fossil fuels, have led to an enhancement of the greenhouse effect - something that has given rise to a global warming. The climate is becoming warmer, a change that has important effects on the nature as well as for humans and their society. Sea level rising, extreme temperatures are becoming more common, glaciers and other ice caps melt and storms becomes more intense when they appear. The main cause is the emission of greenhouse gases into the atmosphere - carbon dioxide in particular.

Patienter med ögonsjukdomar är en stor patientgrupp som förväntas öka, då många av sjukdomarna är åldersrelaterade och befolkningen i världen blir allt äldre. Ett stort antal av patienterna kommer att förekomma på olika vårdavdelningar där de vårdas av annan orsak. Omvårdnad är sjuksköterskans huvudansvar och hennes profession medför att riktlinjer och lagar ska följas i samband med yrkesutövning. Syftet med pilotstudien var att undersöka sjuksköterskors erfarenheter av att ge omvårdnad till inneliggande patienter med olika ögonsjukdomar i anamnesen. Pilotstudien genomfördes med en kvalitativ metod och datainsamlingen skedde genom intervjuer.

In Swedish sheep industry it is desired to have lambs slaughtered evenly distributed over the year. Swedish sheep are generally seasonal breeders with lambs born in the spring and slaughtered in the autumn. Some of the breeds, e.g. Swedish Finewool and Roslag sheep breeds have shown ability to lamb out of season. For increased knowledge on the possibilities to breed for out-of-season lambing in Swedish sheep breeds, the aim of this master thesis is to study the variation in frequency of two alleles in the MTNR1A gene in the three breeds; Gotland, Swedish Finewool, and Roslag sheep.

Information stored on unprotected computers that gets lost or stolen, and falls intothe wrong hands, can easily be accessed by moving the hard disk to a controlledcomputer, or by booting the computer from a removable medium, in order to getaround the operating system login. This is something that largely affects companieswhere customer information, trade secrets and other sensitive information can becompromised. A classic solution to the problem is encryption of individual files, but ithas some drawbacks as it puts a great responsibility on the users and unencryptedinformation can be left by mistake. A better solution to the problem is transparentencryption of the entire hard disk, i.e. that encryption and decryption of informationis performed automatically and without the user being affected.
