Separeringsmodul
In cooperation with the Gislaved company Lerocon AB [1], a separation module wasdesigned as a further supplement to the Module System. The aim of theprojectimplementation was that the separation module could be flexible enough to feed themetal pieces, screws, nuts and other items with large variations of size, appearance andmaterial composition. The module should also be cost effective to manufacture.A separation module is a design which is ment to streamline the work in industries withautomation of the lineoperations. The module feeds the details such as screws, nuts, washersand pieces of metal in a continuous flow in which traps separate the details from each other.Traps may vary depending on the purpose and of the details that are fed. Perhaps it isimportant for the user that the detail-orientation is right after the separation module, whichmeans that all the pieces witch aren´t are fed back in return.For companies and industries in lineoperations that can be made more efficient withautomation, are production flow an important watchword.
"Två hjärnor tillsammans ger mer kunskap än en!" : En kvalitativ studie utifrån fyra lågstadielärares tankar och erfarenheter gällande den muntliga kommunikationen i klassrummet
This study focuses on oral communication in the classroom involving discussion and dialogue amongst pupils, but also between teacher and pupil. The overall aim is to study the choices regarding the group composition and working methods that might occur in four individual teachers? lessons plans with the intention of increasing the pupils? knowledge through oral communication. The main focus is to explore what the teachers think of the choices they make and how they believe these changes affect the pupils. It is also focused on how the teachers perceive their pupils? learning is improved by oral communication and how they incorporate all pupils, especially the pupils who rarely participate in classroom activity.The methods used are qualitative studies using interviews and observations.
Bakterietillväxt i strömedel till mjölkkor
The resting area is the most important place in the barn for the dairy cow, sometimes called the heart of the free stall system. Inadequate design of the lying area, and lack of or poor quality of bedding materials may reduce the hygiene of the stall. Poor management regarding the cleanliness of the resting area may lead to poor animal hygiene and increased bacterial growth. This in turn will lead to increased risk for environmental mastitis as well as impairing milk quality through contamination with spores.
In this literature study the most commonly used bedding materials; straw, sawdust, wood shavings, clean sand, recycled sand, peat and recycled manure solids, are compared to one another with regards to their ability to resist bacterial growth. Effects of adding hydrated lime to bedding materials have also been studied.
Most bacteria need humidity and prefer a quite high water activity to be able to grow.
Kommunikationen mellan sjuksköterskor och äldre patienter inom vården- en metasyntes
Background: Good quality of communication has a significant role and is essential in the care, and there are many factors that have an impact on the communication between nurse and patient. It is important that the interaction and communication is directed to and focused on understanding in broad sense in order to make sure that the meeting between nurse and care taker will result in something positive. Through a greater understanding the cooperation between nurse and the patient will be facilitated, which will create opportunities for both sides to be part of and contribute to a meaningful rehabilitation.Purpose: The aim of the study is to describe how the elderly patient and the nurse experience the communication within the health care, however also to identify what factors that are essential for an optimal communication.2Method: In this study the method that has been chosen is metasynthesis. The metasynthesis method implies that qualitative studies, that illustrate elderly patients and nurses perceptions and experiences of communication within health care, have systematically been reviewed and compiled to a result.Result: The analysis of the study?s results in a composition that consist of the following three themes; the patients and the nurses perspective on how information should be conveyed, the role of the time aspect in communication and the impact of the attitude on communication.
Vedlevande lavar på döda grenar på levande träd i produktionsskog
Saproxylic lichens in managed forests have less substrate available than in unmanaged forests due to the shortage of dead wood. However, a suitable substrate for these lichens could be dead branches on living trees. To this date, there has not been any systematically collected data about theabundance of dead branches on living trees and the lichens growing on these branches in managed forests. The aim of this study was to see where dead branches were located on living trees of Pinus sylvestris and Picea abies, how large the surface area of these branches was and what lichens grewof wood on these branches. The study was made in Finspång, Sweden, where 11 forest stands of P.sylvestris and P.
SAMMANS?TTNING AV MAKROALGER I SVENSKA ?LGR?S?NGAR eDNA sp?rning och klimatf?r?ndringar
The aim of my bachelor?s thesis is to investigate, through a literature review, changes in the
distribution of filamentous algae as well as the general species composition of macroalgae
and diatoms in Swedish eelgrass meadows. I have also studied the possibility of tracking
these algae and diatoms in eelgrass meadows using eDNA methodology. The focus has been
on linking these changes to climate change factors such as eutrophication, temperature
increase, and anthropogenic emissions, and how these affect the health of eelgrass meadows
and their ecosystem services, such as a carbon sink and biodiversity support.
The results show that filamentous algae have increased markedly in coverage in Swedish
coastal areas between 1980 and 2021, especially in sheltered bays, indicating that altered
environmental conditions favor these fast-growing species. Genetic tracking using eDNA
demonstrated that there are functional primers for many species, particularly among brown
algae and red algae, whereas green algae require more specific primers due to greater genetic
variation.
Informal settlements : the world's invisible communities
Since the beginning of the new millennium the world?s population has increased exponentially fast. The majority of this growth has been accommodated for by urbanization of the developing world. This in turn has lead to a wide spread of informal settlements. Thus, areas of urban slums, that have risen illegally on the marginal lands within and at the periphery of the formal city.
Stadsklimat/Gatuklimat :
The purpose of this paper is to understand the climate of the street and how it can be modified to better meet the needs of the street and the user groups. At the same time the conditions of the street and its surroundings also has to be taken into account. To accomplish this it is necessary to have a broad knowledge of the climate conditions in the city. Therefore an overview of the climate elements and how these are modified in the built-up areas are given. The part of the paper which deals with the city climate has a global approach to be able to give an as complete picture as possible.
100 % svenskt foder till mjölkkor :
As for today, a large quantity of protein feeds is imported from other countries to be used in
the Swedish dairy production. The main import is soya from Brazil. The soya-production in
Brazil results in negative consequences for the natural environment in the area, and the long
transport of the feeds requires a lot of energy. The organic dairy production in Sweden is,
with the highest probability going to be forced to use 100 % organic feed to the cows in the
year 2005, due to new EU-rules. These are some of the causes why there are reasons to look
closer at the possibilities to feed Swedish cows with only Swedish feeds.
In this study, I have looked at the KRAV-rules for organic feeding, where the goal is feeding
with only KRAV-approved feeds.
Kompositörers och koreografers idévärld - aspekter på konstnärliga processer
Composers? and choreographers? world of ideas. Aspects of the art process. This inquiry is about the artistic process when composing contemporary music and choreographing modern dance. I have studied three composers? and three choreographers? thoughts about the artistic process and the work that leads to a piece of music or a dance.
Förutsättningarna för ett parallellt generation IV system vid svensk nybyggnation av kärnkraft.
A new build in the Swedish nuclear power system would entail increased re-quirements for the proposed repository, which is adapted after the reactors of today. With a fast reactor, capable of burning nuclear waste, operating in parallel with the light water reactors, the increased requirements on the repository could be reduced.In this thesis, simulations of a light water reactor and a fast reactor have been performed by using the Monte Carlo code Serpent to investigate the changes in the fuel inventory. The light water reactor in the study is a boiling water reactor and the fast reactor of the type sodium-cooled fast reactor and they have been used for three different operation scenarios.By studying the fuel composition and the results from the simulations of the three scenarios conclusions can be drawn. Conclusions regarding the change of the fuel inventory and decay heat in Clab as well as the interim storage facility and in the repository. Depending on the operation alternative the changes dif-fered significantly and especially regarding the mass of burned actinides for different fuels in the fast reactor.The lowest increase of fuel assemblies was meet when using 50 years old fuel with 20MWd/kg U burnout and 2,0 % enrichment for start up of the fast reactor and 30 years old fuel assemblies with 50MWd/kg U burnout and 4,7 % enrichment for the further operation of the reactor.The increase of the number of fuel assemblies was 3174, which is equivalent to 641tons of heavy metal.
Uppgradering av biogas med aska från trädbränslen
The Swedish production of biogas was 1,5 TWh 2011. About half of the production was used as vehicle fuels. The cost for upgrading biogas depends on the size of the biogas plant and its gas production. If the gas flow is low the cost will be high. However, further development of existing upgrading technologies or development of new ones, have good potential to decrease the upgrading cost for small scale biogas plants.
Vilometabolism hos barn och ungdomar med Cerebral Pares : En deskriptiv korrelationsstudie
Background: Cerebral Palsy is usually divided into three subgroups: ataxic, spastic and dyskinetic, where children and adolescents can, because of misestimation in nutrition and energy intake, suffer from weight problems.Aim: To compare calculations with equations with the individual's measured RMR in the subgroups, to see if any equation is more suitable. This could be used as a tool to calculate the resting metabolism at times when it is not possible to perform clinical measurements.Method: The RMR has been measured in 37 children and adolescents aged 3-15 years through indirect respiratory calorimetry. Those values have been compared with calculations from five equations. The results were then analyzed in order to find if any equation is better to apply for calculating resting metabolism for each subgroup.Results: The ataxic group was overestimated by 56.5% of the calculated values. WHO/FAO/UNU?s equation indicates a significantly strong correlation between the measured and calculated values (r=0.85, p<0.05).
Kväveomsättning i gräsmark med olika artantal och artsammansättningar :
This study was carried out at the Swedish University of Agricultural Sciences, Dept. of
Agricultural Research for Northern Sweden. The aim of the study was to determine how plant species richness and diversity influence the nitrogen pools and nitrogen fluxes in the soil. Plant and soil samples from a biodiversity experiment in grasslands were used. Thirty plots with 12 grassland plant species (legumes, grasses, and non-legume herbs), combined from 1-12 species were investigated.
Måltidskvalitet i förskolan : bidrag till ett kvalitetsbedömningssystem
The quality of meals is included in the constant improvement of each preschool. The study is carried out on behalf of the City of Malmö and Environmental Management and focuses on this quality work. By compiling a checklist of meal quality and by identifying what the meal quality means for persons working with the meal (managers, cooks, educators and parents), it is our wish that this will be a help in their quality work. To inspire the composition various organizations working methods and ways to manage, evaluate and make use of different models and tools to improve the dining quality, has been studied. In the literature, the work has received confirmation of theories that emerged during the analysis work of what a meal is and how quality can be measured. The results show that food quality is described as a complex concept consisting of different parts, where the food, atmosphere, service, together form the meal quality. The semi-structured interviews and the inquiry form, have given an indication of the preschool work with quality in the meal activities and it shows that on a wide range and large differences.
