Naturvetenskap och Bilderböcker : Naturvetenskaplig Begreppsbildning och Grundläggande Naturvetenskapliga Matoder

Preschool has a long tradition of using picture books, both as entertainment and as a resource for educational activities. In science there are two main application areas. The first one is science concepts and the second is to teach basic science process skills. These skills, observing, communicating, inferring, classifying, measuring and predicting reflects the methods used by scientists. Picture books potential to put science concepts and activities that promote the use of science process skills in a meaningful context, recommends using picture books for this purpose.

Korsförlamning hos häst : fodrets påverkan

The purpose of this thesis has been to gather knowledge about the complaints of tying-up in horses and to show that the importance of feeding. The thesis includes a literature review of tying-up how preventative measures by feeding can be made. In the equine sport, crosscountry, horses occasionally suffers from tying-up, a muscle disease. An increased knowledge about the disease is demanded by riders and trainers as the disease disrupts training and competition of suffered horses. A cross-country horse works very hard in training and during competitions but the work bouts are long enough for the muscle cells to use aerobic pathways in the metabolism.

När förmänniskan blev den moderna människan

The subject of this bachelor-level thesis in archaeology in the transition from archaic sapiens to anatomically modern humans, and what might have caused this transition. A part of the study aims to prove or disprove whether an increased consumption of shellfish might have caused this development. Another part of the essay deals with the connection of said evolution and the suggested emergence of cultural and ritual practices in South Africa circa 100 000 BP and an evaluation of the arguments concerning the aquatic ape hypothesis, and their usefulness for the subject.The result of investigation of the theory about the increased consumption of marine resources as a probable cause of the last biological step of creating our species points to the conclusion that it is a probable explanation. There is even some evidence that there could be a connection between consumption of marine resources and the "Out of Africa 2"-theory. It is harder to find a proven connection between the suggested emergence of cultural and ritual practices, even some evidence seems to strengthen the idea.

Det ligger nog i deras arbete att vara problemlösare : En kvalitativ fallstudie om HR-funktionens image och identitet ur ett intraorganisatoriskt perspektiv

Introduction: HR departments have been developed to take care of the organizations most important resource: the human being. HR as a function has however faced criticism claiming that the function does not entail any value to organizations. The rest of the organization often have a hard time understanding what HR?s daily work means and thereof not having a clear image of the function?s purpose or the function?s role in the organization Aim: The purpose of this study is to describe the relationship between the organization's view of the HR department (image) and the HR department's image of themselves (identity) in order to create a greater understanding of how the HR function successfully can be a well-functioning resource in an organization's overall business. Methodology: The study was conducted in the form of a case study. We have approached the issues by taking different perspective into account, which includes HR, managers and employees.

The aim of this study was to examine the drinking habits of students at Växjö University. The study included 98 respondents who answered a survey concerning sex, age, living status, social relations, social desirability and drinking habits. The result indicated that male students consumed more alcohol than female students.

Hur många kan klona sig varje måndag? : en studie av hur HRM påverkas av projektifiering

Bakgrund: Projektifiering innebär att företag går från en stark linjeorganisation mot att betona projektdimensionen. Denna förändring skapar nya förutsättningar för medarbetare och torde även ha samband med företagets syn på sin personal som strategisk resurs. Syfte: Syftet med denna studie är att kartlägga och analysera de förändringar som sker inom Human Resource Management i samband med företags projektifiering. Genomförande: Det empiriska materialet består huvudsakligen av intervjuer med nyckelpersoner på Posten och Saab Aerospace. Resultat: HR-funktionen har en viktig roll i projektifieringsprocessen.

Nautikerns möjlighet att reducera bunkerförbrukningen

The work aims to clarify what nautical officers onboard in today's merchant can do to help reduce bunker consumption during the voyage? The question we have asked ourselves during the autumn term in 2008 much was said about the premium bunker prices, and how the future could affect our daily lives as nautical officer. We felt here that the school had relatively little knowledge of the subject and therefore felt that it would be interesting to identify how it really looks like onboard the ships today. To collect information we contacted 7 Swedish companies that operate with different types of vessels, in order to get a broad picture of the whole industry. For shipping companies we asked questions about how actively they were working on the issue and what methods they used.

Storleksoptimering av en etanolfabrik för integrering med ENA Energis kraftvärmeverk. : Baserat på en regional energibalans mellan tillgång på etanolbränsle i Enköping kommun och producerad etanol med hjälp av tillgänglig ånga från ENA kraftvärmeverk.

AbstractThe future of ethanol is depending on good solutions for the production. ENA energy power plant produces electrical power and district heating by heating biofuel. By building an integrated bioenergy plant surplus steam could be used to produce ethanol as fuel to vehicle.This would mean that ethanol is produced renewable energy and the energy for the process derives from the surplus of power.  ENA energy, MDH (the University of Mälardalen) and the energy authority has initiated a research project were different bioenergy combinations integrate with existing power plant.  As a part of the project which size an integrated factory should be to gain the best efficiency for the plant was investigated. Consideration will be taken to the cost of the production in order to be competitive to the price of imported ethanol.  Etanolens framtid vilar på bra lösningar för framställning.  I ENA energi kraftverk i Enköping produceras el och fjärrvärme genom eldning av biobränsle.  Genom att bygga ett integrerat bioenergikraftverk där skulle man kunna använda överskottsånga till att framställa etanol som fordonsbränsle.

En jämförelse av RDF och avfall som förbränningsbränsle

In the EU the amount of waste increased by 14 percent during the years 2000 to 2010. EU?s target to reduce waste generation runs parallel with the aim of increasing the efficiency and profitability aligned with energy recovery. In Sweden the energy recovery through incineration is increasing steadily, and 46 percent of the municipal solid waste (MSW) is treated by combustion. This report aims to examine the profitability of processing MSW into Refuse Derived Fuel (RDF) from an economic-, energy- and environmental perspective.

Lokala skillnader i konsumtion av påväxtalger och terrestra löv hos en differentierad population av Asellus aquaticus

That ecological and evolutionary processes can take place on the same time scale is a recent insight. Today we also know that they are directly linked to each other. In the lake Tåkern, in year 2000, there was a structural change when phytoplankton declined and submerged vegetation, mainly stoneworts began to spread. This led to evolutionary changes in the aquatic sowbug, Asellus aquaticus which had previously been limited to the reed, most likely feeding on detritus. But then, sowbugs could exploit the new habitat in stoneworts and a new food resource in terms of periphyton.

Majsensilage i Sverige

Maize for silage has been used as fodder in different parts of the world for a long time and has recently become more common also in Sweden. Our cold climate has been a problem as maize is very sensitive to low temperatures and frost. With new varieties and better techniques for cultivation it is now possible to grow maize in the southern and middle parts of Sweden. As for the north of Sweden the length of the cultivation season is a limiting factor as there are too few days with temperatures of over +10 ºC. Maize is well suited for silage making but oxygen-free conditions are required.

ZigBee-teknikens möjligheter att trådlöst överföra EKG-signaler

In many clinical applications, it is desirable to transmit sensor information wireless. In earlier research, investigation transmit ECG signal using Bluetooth, was performed. However, when Bluetooth has some drawbacks it is of interest to investigate alternative methods, one such method is ZigBee. Bluetooth has higher data rate speed (1Mbps) than ZigBee (250kbps). However, Bluetooth consumes more power.

Handarbetets sociala rum - om emotionshantering och kollektiv identitet i handarbetsrörelsen

The purpose of this thesis is to investigate emotions and collective identity in the handicraftmovement. Which are the collective identities of craft movement, and is it possible to speak ofan over all collective identity among the handicraft people? I will also examine the emotion workboth on individual and group level.Eight qualitative interviews were conducted to achieve the aim of this thesis. Research haspreviously drawn attention to handicraft from a gender and a historical perspective but neverfrom an emotional one. The theoretical framework derives from an emotion sociologicalperspective where Collins interaction rituals, emotional energy and Hochschild?s emotionmanagement is the main theses.

Resource planning for internal logistics : A tool designed for the material handling department at Scania Axles and Gearboxes

This master thesis is performed at Scania Axles and Gearboxes, a production plant located in Södertälje. Within the plant axles, gearboxes as well as central gears are assembled from components to finished products. All production is conducted on production lines, with a pre-determined rate, which is supplied with components by the material handling department. Since the production quantity and the mix of product variants produced on the production line is customer order-based, the number and type of components needed for production as well as appropriate staffing within the material handling department is difficult to predict. Scania is currently using a number of different resource planning tools for each material handling-department within Axles and Gearboxes to visualize the workload within the departments.
