Bärförmåga i skjuvning för råspontpaneler. Laboratorietest och FE modulering

AbstractIn the fall of 2003 a project was started in the Swedish building sector that is called BASTA (the building sectors’ termination of especially harmful substances). The project is operated by the building companies NCC, Skanska, PEAB and JM, the Swedish Building Industry and the Swedish Environmental Institute IVL. The purpose of the project is to create a common environmental assessment system for the entire building industry and with the help of this system phase out the use of especially harmful properties from building products.In a large sense BASTA works like this; On the BASTA web site there is a database, to which a supplier can register the company and the company’s products. Only those products with a substance content that fulfil the demands of the BASTA system, is to be registered. As it is the supplier himself that carries out the registration of the company and the company’s products to the system, the BASTA-organisation annually controls that the companies that are registered in the database, fulfils BASTA’s demands.Since NCC is one of the companies that operates BASTA, BASTA is probably going to be the environmental assessment system that is recommended for the company in the future.

Issues of the magazine, published in 2009 and on, is analyzed and dissected to better understand and be able to get answers for the questions of issue. What is said in the magazine, and how does the message reach the audience? Furthermore, the message, as well as the tone used to convey it, is reviewed as part of the discussion about consequence.

Språkutvecklande arbetssätt : En kvalitativ studie om hur lärare arbetar med halvspråkiga elever

The purpose of this study was to examine how teachers conduct their teaching to be language developing, and how they in a practical way work with semi-speaking students who have language deficits in the Swedish language and / or their native language. To carry out this study, I used qualitative interviews as a method and I have interviewed six teachers working at a high school.The school that these teachers work at execute a language developing teaching throughout all the courses in the school. All teachers have a similar idea of what language developing work is, however, how they go about and what is emphasized most in the teaching differs. The reason for this is because these teachers have different experiences with the language developing teaching. These professionals agree that this approach is very important and that all teachers, regardless of subject, should work in a language developing way, in parallel with the rest of their subjects.

Läraren i praktiken : En studie om lärares förmåga att inspirera och medvetandegöra elevers inlärning, samt omforma sina akademiska ämneskunskaper

Denna uppsats, Läraren och den praktiska verkligheten, handlar om hur lärare gör föratt omforma sina ämneskunskaper till ämnesdidaktiska, vilka metoder de använder iundervisningen för att medvetandegöra elevernas inlärning, samt hur lärarna gör för attutmana och inspirera elevernas lärande och kunskapsutveckling. Teorierna som använtsi studien är läranderum, proximala utvecklingszonen, autonomous learning, learning tolearn och pedagogical content knowledge, vilka även ligger till grund för denanalyserande delen.Resultaten i studien visar att en fungerande gruppdynamik är avgörande för en godarbetsmiljö, en ständig dialog utifrån elevens perspektiv bör föras för att skapamedvetenhet hos eleven gällande lärprocessen. Utveckling av självständigt lärande skergenom tydlig kommunikation mellan lärare och elever, det vill säga att läraren är tydligmed anledningen till arbetsområdet, informationen kring anvisningarna, samt finns somen tydlig vägledare för att guida eleven genom ämnet. Vidare handlar omformning avämneskunskaper för lärare i praktiken om att reflektera, utvärdera och utvecklaplaneringen och den genomförda undervisningen..

Värmeöverföring från smälta till vattenkyld tapputrustning

Examensarbetet är utfört på smältverket Rönnskärsverken på uppdrag av Boliden Mineral AB. Kopparhyttan är en elektrisk smältugn för smältning av kopparslig och sekundära material i form av askor, fragmenterat skrot, krossad skärsten, slagger och slam. Beroende på hur det ingående materialet varierar kommer smältans kemiska sammansättning att variera. Variationerna i smältans kemiska sammansättning medför också att de fysikaliska egenskaperna hos smältan varierar och därmed också värmeöverföringen mellan smälta och tapputrustning. En hög värmelast på tapputrustningen medför ett ökat slitage på tapputrustningen och därför behövs en förståelse för de bakomliggande orsakerna för att förebygga och om möjligt undvika detta.De genomförda analyserna visar på att en hög värmelast på tapputrustningen framförallt är kopplad till kopparhalten.

Vem ska integreras och hur? En diskursanalys kring hur integration konstrueras då den kopplas till invandrare kontra då den kopplas till nationella minoritetsgrupper

In Sweden there is an integration policy and a policy for national minorities. The integration policy aims to integrate newly arrived immigrants (nyanlända invandrare), whereas the minority policy aims to maintain and strengthen the rights of the national minorities. The national minorities are though, at times, included into the integration policy, even though they hold a minority status in Sweden. This paper aims to, through discourse analysis, investigate the research question: ?how is the content of integration referred to, when it is related to immigrants, contra when it is related to national minorities?.

Sticklingsetablering av Sedum spp. för gröna tak : biokol som organiskt material i substrat

The popularity of vegetated, or green roofs, has grown over the past years due to their potential function of maintaining urban environment quality. The aim of this study was to investigate if substrates with different organic material, peat and charcoal, with two contents (3 or 6 weight%) influenced the growth of the cuttings during the first critical period of the establishment. Biochar is used as amendment to agricultural soils and has, theoretically, many of the properties suitable as organic content in green roof-substrates. Peat is one of the materials that is commercially used in green roof industry. The substrate has been treated with different amounts of water.

Systemanalys av skogsbränsletransporter :

At the end of 70s and the beginning of 80s, 18 terminals was built and used for chipping wood residue from clear cuttings. Most of the terminals was terminated before the 2000s but with the high oil- and energy prices that we can see today there might be a place for these terminals again. The goal with the study was to analyze and compare economical differences between 5 different logistical systems, collected data was used with a set of formulas. The systems include long range transport of slash, chips and bundles. Three of the systems include transport by lorry to industry the last two includes a terminal with access to train transport.

Modellering av reflektans från ett sockerbetsbestånd med hjälp av en strålningsmodell

The Multispectral Canopy Reflectance Model (MCRM) by Kuusk (1995) has beenused to simulate the reflectance of a sugarbeet canopy. The simulated reflectancevalues show high absorptance in the VIS area, compared to field measurements, andhigh reflectance values in the NIR area. The errors may be due to overestimation ofclorophyll content in the sugarbeet leaves and scattered light during fieldmeasurements. The estimation of the clorophyll content where carried out using thePROSPECT-model by Jacquemoud & Baret (1990).During the vegetation period, the state of the canopy moves towards a closed canopy,with sparse vegetation in spring. The MCRM-model was used to perform a ?spring?simulation, which was compared to the original simulation.

If yes, in what way? Which communication strategies were used? Did the company mediate an unequivocal message and how was the information framed? Did any aggravating factors, which worsened the organization?s reputation, appear? How did Malaysia Airlines manage possible rumours? Was the word contact used as a keyword? The method of choice is a quantitative content analysis and the material consists of 20 different analysis units. These analysis units were collected from social media and Malaysia Airlines website. The quantitative content analysis is based on the theory Situational Crisis Communication Theory, taken from PR, Strategy and Application, Managing Influence, by W.

Fanan, förrädarna och friheten : Musiktexter med ideologiska teman från Tredje Riket till Vit Makt-rörelsen ? en komparativ textanalys

The making of a cultural historical exhibition usually involves the collaboration of two categories of professionals: the curator, in charge of the exhibition content, and the designer. From these positions, representing content and form, the team is in charge of cooperating towards a shared goal ? the exhibition ? which is the spatial expression of ideas.This MA thesis is based on my work experience as a designer of cultural historical exhibitions. By means of situations where my perspective collided with that of the museum curators?, I examine our different concepts on a number of issues: the meaning of an exhibition; the process; and the perception of what our respective roles are.

The prehospital management of patients with acute myocardial infarction (AMI)now includes 12-lead electrocardiogram transmission directly from the ambulance to hospital.If the ECG shows ST-elevated myocardial infarction the patient should be transported directlyto a hospital with capability for percutaneous coronary intervention (PCI).                                               Aim: The aim of this study was to describe how ambulance nurses experienced the prehospital management of patients with AMI who are transported by ambulance directly to hospital for PCI.                                                Method: Semi structured interviews were conducted with eight ambulance nurses. Data were analysed using qualitative content analysis. The categories that emerged were: Use ofcompetence, Responsibility and Insufficiency. Result: The result showed that the ambulance nurses felt secure when they cared for patients transported directly to PCI. The nurses assessed the patient and decided how he or she should be cared for.

?Det är trevligt att bläddra?? : om anledningar till varför man läser papperstidningar

Purpose/Aim: To investigate why people in the age group of 30-40 subscribe to the traditional morning newspaper even though they can get the same information at a much lower cost from for example TV, the internet or the free daily papers. The aim is to also look at possible future alternatives to the traditional morning newspaper.Material/Method: Focus group interviews were used to gather the empirical material. These consisted of a total number of twelve people, divided into three groups. The results from the focus group interviews were analysed with help from established uses & gratifications theories and two diffusion theories.Main results: This study shows that people read the traditional morning newspaper to get a good mixture of entertainment and local, national and global news. It is relaxing to read the newpaper on paper compared to reading it on the internet, mainly because you get a good overview which makes it a lot easier to find exactly want you want to read.

Anestesisjuksköterskors upplevelser av sin fysiska och psykosociala arbetsmiljö

Health care is increasingly complex, which increases the demand for knowledge and expertise. Despite this, the share of specialized nurses, including anaesthesia nurses, has decreased from 65% to 48% from year 1995 to year 2008, according to statistics from the National Board of Health and Welfare (Socialstyrelsen) in 2010. Studies indicate that there may be various factors in the work environment that anaesthesia nurses, choose to leave the anaesthesia profession. The purpose of this study was to examine how anaesthesia nurses experienced the physical and psychosocial work. The study was conducted as a descriptive study with qualitative approach.
