Nature of science i skolans tidigare år - Intervjuer med lärare som integrerat Linnés 300-årsjubileum
För att alla elever ska kunna uppnå scientific literacy bör man utgå från barnens erfarenheter där naturorienterade ämnen, NO, knyts till ett sammanhang ? en kontext. I kontexten synliggörs naturvetenskapens mänskliga sida, och därmed visa att NO är mer än fakta. Elever behöver lära om naturvetenskapen, vilket kallas nature of science, NOS. Vårt syfte är att ta reda på hur lärare aktualiserar nature of science genom ett Linné-tema.
Säkerhetsklassificering av dammar : En kartläggning av system i Sverige, Norge, Finland, Schweiz, Kanada och USA
In a comparing survey this thesis investigatesclassification systems for dams in Sweden, Norway,Finland, Switzerland, Canada and USA. Theinvestigation is aiming at an understanding of howpotential consequences of a dam failure are takeninto account when classifying dams. Furthermore,the significance of the classification, regarding therequirements on the dam owner and surveillanceauthorities concerning dam safety is considered andreviewed. The thesis is pointing out similarities anddifferences in the line of dam safety.The survey of dam safety is firstly based upon legalrequirements in the different countries andsecondly on guidelines regarding dam safety. Damowners generally are ultimately responsible for thesafety of their dam, and often have their ownroutines regarding how this safety is to be achieved.In this thesis, however, the legal requirements aremainly focused upon.The investigation has resulted in an outlining ofeight areas, where the classification systems in thevarious countries have been compared.
BarnABC
This project is a learning CD-ROM production aimed at first-time parents. It is
using both sound and images, moving as well as non-moving. The purpose of the
production is to be an interesting alternative to traditional books. We have
been looking at similar productions like drivers license educational CD-ROMs
and encyclopedias for inspiration and ideas on how to proceed. In order to give
the content some dynamics, we've also added the element of 3D-animated
sequences.
The application is supposed to be run as a simple executable file with flash
embedded.
Klinisk gradering av hästens luftvägsstatus : en jämförande studie av kliniska graderingsprotokoll samt deras relation till luftvägshälsa och neutrofilförekomst i BAL-vätska
Respiratory disease with airway inflammation as main characteristic is common in the horse. It is a syndrome that is not yet fully understood. The etiology, pathogenesis and classification into different disease states are subjects for discussion and under continuous revision. Despite a number of modern techniques, the diagnostic procedure is challenging. There is no test considered to be gold standard when diagnosing these diseases.
The economic consequences of Striga hermonthica in maize production in Western Kenya
Kenya is a country of 35 million people and is situated in Eastern Africa. 70% of thepopulation works within the agricultural sector and for many of them food insecurity is amajor problem. Maize and beans are today the staple food for many households. Goodfarming conditions enable two harvests per year and a potential maize yield of 4-5 tons perhectare.A major problem for many farmers in this area is the increase of the weed striga. The weedcauses severe yield losses, and has a major economic impact on smallholders.
Implementering av CRM
Background: The fierce competetivness that characterize todays market force the companies to differentiate their offerings to a greater extent. The customers do no longer choose their supplier on the attributes of the products alone. Their purchase decisions also depend on the relationship the customers have with their supplier. With new customer channels like the Internet and advanced computer systems companies can increase the value for their customers through a better understanding of the customers needs and preferences. In this way companies can create longterm relationships with their customers.
8263 kilometer: En studie i avståndets påverkan på styrsystem
The aim of this Master?s thesis is to study the effects that geographical distance have on the control systems in a scattered organization and how this, ultimately, affects the employees in terms of loyalty and motivation. In order to do this, a case study has been conducted on a multinational travel group and its local branches in Thailand. The study is based on a selected number of theories focusing mainly on control systems in multinational contexts as well as on theories regarding communication and autonomy. The conclusion of the study is that geographical distance has led to a rather large autonomy for the local branches and that the headquarter to a large extent rely more on formal control.
Kognitionsforskning i djurhållningen: grisars kognition och dess tillämpning vid slaktsvinshållning
Pigs are often mentioned as relatively intelligent animals when compared to other nonhuman species. Despite this knowledge, the vast majority of pigs are kept under conditions that lack opportunities to satisfy their cognitive needs. Therefore, a need to evaluate the present scientific studies about pig cognition was acknowledged, in order to evaluate to what extent the knowledge is applied in the husbandry of finishing pigs. If a considerable lack of application was determined, suggestions about how to use the obtained information to improve pig welfare were also to be made.
A synthesis of the present literature was made, and it could be concluded that a considerable amount of studies had been carried out in the present area. The pigs of today appear to have the same behavioural and cognitive needs as their ancestor, the wild boar.
Datorn - vän eller fiende? : En jämförande studie mellan elevers datoranvändning utanför skoltid och betyg i engelska
Barn och ungdomar ägnar idag en betydande del av sin fritid till datoranvändning. I denna uppsats har vi valt att undersöka datoranvändningens eventuella effekter på ungdomarnas betyg i språk. Uppsatsens syfte är att undersöka om man kan se samband mellan, dvs. positiva eller negativa effekter på, betygen i engelska hos elever i år 9 och deras datoranvändning utanför skoltid. Utifrån detta har vi även undersökt vilken typ av datoranvändning som har dessa effekter, hur lång tid framför datorn som motsvarar dessa resultat, samt om det finns skillnader mellan flickors och pojkars datoranvändning och deras mätbara språkkunskaper.
Jämförelse mellan neurala nätverk baserad AI och state-of-the-art AI i racing spel
Denna rapport jämför prestandan mellan state-of-the-art AI-botar i racing
spelet TORCS och en AI-bot
som kör med hjälp av ett artificiellt neuralt nätverk (ANN-bot). ANN-boten, som
implementerades som
en del av arbetet, använder en feedforward arkitektur och backpropagation för
inlärning. Ett separat
program som användes för att träna det neurala nätverket med träningdata som
spelats in från TORCS
implementerades också. Som state-of-the-art AI-botar användes AI-botar som har
använts i en tävling.
De fyra AI-botarna testades på åtta olika banor och data om hur lång tid varje
varv tog och hur snabbt
AI-botarna körde sparades och sammanställdes. Resultaten visar att på banorna
som ANN-boten klarar
av att köra runt så är ANN-boten snabbare än en den långsamaste
state-of-the-art boten, men ANNboten
klara inte av majoriteten av banorna som den testades på.
Human Stem Cell - European National Innovation Systems and Patents
The purpose of this paper is for the reader to realise how national innovation systems are deeply intertwined with the legal background of a country and to understand the processes that involves national innovation systems specifically regarding the stem cell / genetics research and how the need for specific community law must be considered targeting the stem cell patents. The legal part will try to answer: Why is it important given the actual state of the European stem cell national innovation systems for the European Commission to take a stand and tackle issues regarding the patenting of the human stem cell innovations? This is done from a country industry analysis (business approach) and then linking it with competition law from a community stand point of view (that tackles biotechnology issues). In order to achieve this the paper is divided into three separate analyses beginning with a theoretical background of general biotechnology / genetic terms that will enable the reader to have a general understanding of the importance of this kind or research ( genetics / stem cell research). The chosen countries case studies exemplify very diverse economies and development perspective from the traditionally R&D intensive to the least and from the biggest countries in Europe to one of the smallest, thus giving cultural, legal, economic and scientific variety..
Ungdomars fysiska aktivitet och dess betydelse för prestationen i skolan
This study where designed to investigate if there are any positive relationship between the extent of physical activity during adolescent's leisure time and the academic performance, and also if there are any negative relationship between the academic performance and the time spent in front of the television or computers. Another part of the study tried to find out if physical activity has a direct and immediate influence on the performance in school. 91 pupils (51 girls and 40 boys) in the 8:th year of the Swedish primary school, from three different schools participated in the study. All 91 pupils first responded to a questionnaire concerning there activities in leisure time. They where then tested in a mathematical test and the results where compared with the extent of physical activity and TV/computer time they had stated in the questionnaire.
Battlestar Galactica : Ett mänskligt universum
Science Fiction har sedan sin uppkomst gestaltat samhället och de samhällsfrågor som för sin tid är aktuella. Alltifrån ifall människans existens är kroppslig eller andlig, till vad som händer när livsformer från andra planeter kommer till Jorden, har diskuteras i Science Fiction. I tv-serien Battlestar Galactica gestaltas och problematiseras vår samtid. Genom att flytta mänskligheten från Jorden och ut i rymden, där de konfronteras med en mängd etiska och moraliska frågor ? tvingade att se över vad de själva är och vad de håller på att bli.
Förutsättningskontroll och nedbrytningstest på oljeförorenad mark : Preem 2, Karlstad
More frequent and intensified rainfalls are expected to occur due to climate change in the nearfuture. This together with a higher proportion of paved areas increases the pressure on today?sstorm water systems (Risinger, 2014; Boverket, 2013; Stahre, 2006). Traditional storm watersystems (i.e. underground pipe systems) have during last decades started to be questioned(Olshammar & Baresel, 2012).
Alternativa byggsystem för att minska transmissionsförlusterna på miljonprogrammets byggnader
The purpose with this project is to explore and verify three renovating systems for Miljonprogrammet (common expression forbuildings constructed during the years 1965-1975 when over a million houses where built in Sweden) to take measure to thelargely transmission losses of these buildings. Many of the buildings from this period have similar constructions and thereforethe same techniques can be used to renovate several of them. This project only considers the climate scale, although thereare many more factors to concern for to efficient the buildings of Miljonprogrammet.This thesis presents examples of renovations carried out using two of the three renovation systems.The essay presents a reference house of choice on which we apply the three systems and calculate the new U-values,consumption of energy and the investment costs. The new U-values the building is given is matched to the values ofrecommendation for passive houses. Our reference house is a two story apartment building, located in the village ofLammhult, with brick facades at the ends and plaster at the long sides.
