Kartläggning av energianvändning under byggfasen vid nyproduktion av flerbostadshus
The energy consumption in the sectors of residential and public buildings is 40 % of the total energy consumption in Sweden. The main part, 85 %, of the energy use in these sectors is for operation of the buildings. The rest is used in the building process. When energy-efficiency measures are taken the energy use during the operation time decreases and the fraction of energy consumption during the building time increases. This project is carried out in cooperation with JM AB and concerns the energy use during the building time of production of blocks of flats at the building site.The main part of the electricity that is used during the production of apartment buildings goes into the heating of portacabins and illumination of the building during the construction phase.
Att skydda sig mot onda ögat -fallossymbolen och andra beskyddande symboler under antiken.
As long as envy and the will of harming others for what they possess have existed, the evileye has been a present belief system in many cultures around the world. This study, based onarchaeological evidence and texts by ancient writers that reflect this ancient superstition,explores how the evil eye was being averted and practiced by ancient cultures. What measureswere taken to ward off the evil eye? How have these measures been represented in thematerial culture? What can we learn from the context of the material culture involving the evileye? Discussions and theories of protective measures that have been depicted on the walls ofthe roman city of Pompeii will hopefully give a wider comprehension of the evil eye, and its influence on Roman society..
Tillit och engagemang i organisationer
Previous research has shown that there is a relationship between trust and organizational commitment. Our research questions were if the three trust-variables ability, benevolence and integrity predict organizational commitment differently. Further we examined if the length of employment affected the relationship between benevolence and organizational commitment. Due to the fact that past studies has shown that benevolence develop during a longer period of time than do the other trust-variables. We made a survey using questionnaires (n=50) in a ?caretaking facility? and using a multiple regression analysis we found that ability was a significant predictor (p=0.032) for organizational commitment.

AESA-teknik för framtida artillerilokaliseringsradar, en nödvändighet eller lyx?
Vi lever i en värld där teknikutvecklingen går allt snabbare och till synes exponentiellt och oförtröttligt kommer att fortsätta öka. Hur detta påverkar Försvarsmaktens val av tekniknivå för framtida sensorförmåga för artillerilokalisering kopplat mot operativa krav, interoperabilitet och ekonomi blir extra intressant när radartekniken befinner sig i ett generationsskifte. Beprövad teknik, internationella och militära krav på en artillerilokaliseringsradar ställs mot ny radarantennteknik, svensk forskning och utveckling av Aktiva Elektroniskt Styrda Antenner (AESA).Syftet med denna uppsats är att undersöka huruvida ny teknik är ett nödvändigt tekniksteg för artillerilokalisering eller är "gårdagens" teknik lika bra eller kanske till och med bättre i vissa användningsområden och situationer? Är AESA ett nödvändigt tekniksteg för artillerilokalisering?Metoden för uppsatsen är en jämförande litteraturstudie d.v.s. en kvalitativ textanalys utifrån en given teoriram.
Variationer i normal språklig förmåga hos vuxna jämfört med neural aktivitet
Since the brain is an important prerequisite for human language there is a great interest to gain more knowledge about healthy brain activity during language mediated communication. This study examines variations in high level language ability relating to demographic factors like gender and age and relates language ability to neural activity.Eighteen individuals in ages between 22 and 64 were included and divided into groups in relation to gender and age. The material used to assess language ability was derived from Testbatteri för Bedömning av Subtila Språkstörningar (Laakso, Brunnegård, Hartelius & Ahlsén, 2000), Swedish Lexical Decision Test (Almkvist, Adveen, Henning & Tallberg, 2007) and a reading test (Högskoleprovet). The results were correlated with measured brain activity using functional Magnetic Resonance Imaging (fMRI) and language paradigms. ANOVA was applied to discover possible demographic variances in language ability as well as in brain activity.The results showed no significant differences in language ability.
Removal efficiency of perfluoroalkyl substances (PFASs) in drinking water : evaluation of granular activated carbon (GAC) and anion exchange (AE) using column tests, and the effect of dissolved organic carbon
Poly- and perfluoroalkyl substances (PFASs) are a group of environmental contaminants that have gained increasing attention due to their potential to bioaccumulate, environmental persistence and potential toxicity. PFASs have been found in surface water, sediment, air, soil, sludge and ice caps globally, as well as in wildlife and humans. Furthermore, PFASs have also been detected in drinking water, leading to raised concerns for human health, since drinking water is one of the most significant sources of PFASs for the general population. Conventional water treatment techniques have shown to be ineffective removing PFASs, highlighting the importance for further research to develop efficient removal techniques.
The aim of this study was to investigate the removal efficiency of PFASs in water using two treatment techniques; granular activated carbon (GAC), type Filtrasorb 400®, and anion exchange (AE), type Purolite A-600. Additionally, the effect of dissolved organic carbon (DOC) on removal efficiency was studied.
Simulering av energieffektiviserande åtgärder för små- och flerbostadshus : Möjligheter för JM:s hustyper att uppnå passivhuskonceptet vid nybyggnation
The purpose of this project was to evaluate how energy efficiently some of JM?s residential buildings can become in standard production. What kind of measures are needed to achieve the level of energy demand that is included in BBR12 (Boverkets Byggregler)? What measures are needed for achieving a lower demand so that the buildings could be classified as passive houses? The investigation has included a single family house and two different types of apartment blocks.The simulation programs Enorm and VIP+ have been used to calculate the energy demand of the buildings. The results from the programs have been compared with the measured energy demand for the three buildings.
Återinläggning av patienter 80 år och äldre på medicin- och kirurgklinik
ABSTRACTThe aim of this study was to describe various methods of treatment and effects of treatment of ADHD, and to investigate wheater there is an association between adults with ADHD and obesity. Method: Literature review. Twelve quantitative scientific articles were found in the data bases PubMed, Cinahl and MedLine. Result: ADHD is a cognitive impairment that can lead to serious complications such as obesity. Studies show that drug treatments of adults with ADHD have positive effects in terms of reduced symptoms, increased efficiency and improved quality of life, but drugs can also cause side effects in form of loss of appetite and insomnia. For adults with ADHD and obesity drugs that affect metabolism have a significant impact on patients ability to lose weight.
Energiförbättrande åtgärder på befintliga flerbostadshus : -En lönsamhetsanalys
The EU Council adopted in 2007, environmental and energy goals with the aim of them must be met by 2050. This, in combination with those of the Swedish government 15 enacted environmental goals is supposed to lead the way for the Swedish environmental work.This report has examined measures in properties in the Swedish Cooperative Housing Society (SKB) stocks.The report discusses a range of measures that might be appropriate to apply on the properties to make them more energy efficient.One of the measures discussed, the vent whose primary purpose is to create a good indoor environment for the residents but is also where the most energy is lost.Another measure discussed is insulation of the building envelope on the estate to make it more energy efficient. To put extra insulation on the building envelope is important because of the large amount of energy that is lost through the walls, ceilings and floors.Future actions that may be implemented is individual billing of heating and hot water. This system has been used in European countries since the 70's and today the EU wants to increase the own individuals control over their electricity costs. This has led to a discussion whether to implement the system in Sweden or not.However, there are a number of equitable measures to be sorted out before the system can be used in any great scale.Finally, it is important to remember that environmental measures should be the primary and the pursuit of cost reductions the secondary otherwise you risk the environmental work to be counterproductive..
Nivågruppering i Engelska : En fallstudie på en gymnasieskola i en Stockholmsförort
The purpose of this degree thesis is to investigate what the English teachers in an upper sec-ondary school, think about teaching students in ability grouped classrooms. The questions that I have set out to investigate include what the teachers think about ability grouping in English, the school?s current organisation of ability groups, the pros and cons of ability grouping in English, differentiation in teaching and if students get more individualized teaching with abil-ity groups, how the teachers cooperate and what would be the optimal teaching situation in an English learning classroom.I did a lot of theoretical research on the subject and studied old essays on similar subjects. I also did some classroom observations to use as background information for my interviews. I interviewed five teachers of different sex, age, and teaching experience.
Nivågruppering
The aim of this essay is to examine if the attitudes and the experiences of Ability Grouping are the same on different levels of the school organisation.I have chosen to answer the following two questions:· Have the teachers, the students and the headmaster the same idea concerning the educational model at the school, that is, the pros and cons of Ability Grouping?· Does the intentions of the curriculum agree with this educational model?I knew what I thought about the educational model at the school that is the object of this essay, after spending ten weeks at it as a trainee, but I felt that I would be interesting to know what the people who are part of that system everyday think about it.In order to be able to answer my questions, I used both the qualitative and the quantitative method. I interviewed the headmaster and five teachers to find out what they thought about Ability Grouping. I also distributed inquiries to 70 students from 6th to 9th grade to get their point of view. In the theoretical discussion I explain the meaning of different conceptions that I use throughout this essay.
Energikartläggning av polishuset i Gävle : Åtgärdsförslag för ett minskat energibehov i fastigheten Gävle Söder 17:10
The objective of this work was to introduce measures to reduce energy and water demand at Gävle Söder 17:10. To succeed, this energy audit has been made. The work is based on collected statistics from the property owner Norrporten, measurements, literature review and through consultation with experts in the field. Two models, one for each building, have been created in the simulation program BV2 to estimate the potential of energy measures based on the collected information. The models in BV2 have been verified against the statistics of the energy consumption.With the help of calculations and simulations, seven cost-effective measures have been identified.
Jämställdhetsplaner : Arbetslivets tysta arbete
The purpose of this essay is to examine how gender equality can be used in the workplace, its possible effects, and what collaboration can contribute to the subject of gender equality. A combination of legal sociological and legal dogmatic methodology has been used to examine the EU and Swedish law, how equality should be approached and what previous studies have concluded. An interview has been conducted to provide a clearer picture of how gender equality appears in practice, in the modern workplace. An equality plan should be conducted every three years and applies to employers who are responsible for more than 25 employees. The manual should include a description of the measures considered necessary in the workplace in order to promote gender equality. How an equality plan should be developed is not specifically outlined in the current law, and thus this is left up to the employer to determine.
Gruppchefens förmåga
The Swedish armed forces has for many years educated squad leaders by letting them start their training two and a half months before the soldiers start their training. 2007, this system was used for the last time. I went trough this system myself in 2005 and had a positive experience and when I did my internship I experienced a slight difference in the attitude of the squad leader. I talked with my colleges at the company and they had felt the same. This essay will try to analyse if the squad leaders has lost any of there ability and if so, what could be the cause? To analyze the ability of the squad leader in this essay it will first analyze their ability through the Direct leadership theory, which is the theory that is presently used in the Swedish armed forces.
