En undersökning av specialpedagogiska perspektiv inom ridterapi
Background: Investors have several options to choose from when the goal is to achieve the highest yield at the lowest cost and risk. Stocks are a common investment options, but is also associated with risks. Portfolios are usually constructed with several different assets to reduce the unsystematic risk of investment. Funds are similar to composite stock portfolios, the big difference is that they dealt with in their entirety and investors may not affect the fund's content. The problem remains that whether you choose stocks or mutual funds there is still uncertainty as to how the future will unfold.
Hackelselängdens betydelse för tuggtid och foderkonsumtion hos mjölkkor :
Today, our cows experience a harder pressure to achieve higher milk yield. To manage this challenge the animal needs first class feeding and treatment. An important aspect of the feeding is to fulfil the need from the cows of especially fiber; and fiber with a sufficient proportion of long particles. Both too much and too little fiber is bad for the wellbeing of the cow, and she might get diseases like acidosis.
Many models for feed management have been developed to secure that the animal gets enough of e.g. fiber with a sufficient proportion of long particles.
Engagerade ungdomar : en hållbar energistrategi
The consumption and energy use in today's society contributes to the on-going climate change that creates a debt of life quality for future generations (www, DN, 2007, a). The resources that are used by humans exceed by far what is sustainable (www, Regeringen, 2007, a).
The purpose of this paper is to examine how a message about energy conservation should be designed to reach youths. This will be attempted by showing their thoughts on energy and environmental issues and also what it would take for them to get more involved in these issues. The views of the youths are gained by a number of focus group-interviews, which where carried out in the fall of 2007, with kids in the ages 12 to 19. Apart from these interviews, interviews where also conducted with representatives from different youth organisations in Sweden, which gave their views on how to get a message across to kids.
Framtagning av beräkningshjälpmedel för tvärkraftbelastade förband med förbindare av metall.
The governing set of regulations for structural engineering in Sweden used to be Boverket, BKR. However in the beginning of the 21st century a changeover to new regulations, the Eurocodes, started.The transition was completed in year 2011 when the Eurocodes became the mandatory design work policy for all countries within the European Union. The Eurocodes were implemented to simplify and remove potential barriers to trade that may exist when countries have different design rules. Since the changeover it has been important for all construction companies to update their knowledge base and their design software.When comparing the two calculation processes they seem similar, but there are a couple of differences worth noting. With the new regulations, engineers will find that the process when designing joints in timber structures has changed. What used to be a fairly easy and straight forward calculation procedure has now become tedious and time consuming.The objective of this degree project is to present a product, a dimensioning tool that will help structural engineers when computing lateral load carrying joints in timber structures.The degree project is made up of two parts where the first part is the written report describing the background and theory behind load carrying computations. The second part of the project is the actual dimensioning tool which includes several worksheets in Microsoft Excel. The program treats single and double shear connections of the following:Nail jointsScrew jointsSteel plates (thick and thin types) The user can edit the following parameters:Type of plate/ number of shearsStrength class of timber membersMember and plate sizeType of fastenerDiameter of fastenerLength of fastenerYield moment of fastenerkmod and partial factors for design load carrying capacityThe dimensioning tool was created and developed in collaboration with structural engineers at the company Byggteknik AB.
Dammsäkerhetsanalys via stabilitetsberäkningar för Långströmmens kraftverk : En jämförelse mellan olika dimensioneringsmetoder
A detailed dam safety evaluation (in Sweden called FDU) was performed in 2009 by WSP where stability control was performed for Långströmmen power plant with associated spillways. This evaluation concluded that stability could not be ensured, and risk of sliding occurred. The evaluation is based entirely on the recommendations outlined in RIDAS, the power companies guidelines for dam safety, and it is clear that extensive renovations are necessary to stabilize the dam.In this work, the stability will also be checked with guidance through new proposals on guidelines for concrete dams sliding stability, ELFORSK?s report 08:59. This report considered the guidelines in RIDAS as oversimplified, both from an international perspective, but also with regard to the current state of knowledge regarding dam safety.
Evenemang : Great event of Karlstad & Mariebergsskogen
In my study I have chosen to examine the mathematics in children's free play and everyday situations, with focus on sorting and classification. The purpose of the study was to see how children express their mathematical knowledge. I have chosen to use a qualitative method in my examination, here I did observations in a children's group where the children were between three and six years old. I also did interviews with the teacher's on the department to see how they relate to the mathematics and how they formulate the department to achieve as good a learning environment as possible.The result shows that the teacher's approach is incredible important to the children's learning ability and that they are always present to challenge and discuss together with the children. The observation indicates that children use mathematics all the time in their everyday situations and that it is the interaction between individuals and environment that affects children's development. .
Haspelsystemet Camcoil 1500
Our employer Camatec Industriteknik AB gave us the assignments to increase theirs range of versions on Camcoil that is their own patent product. Camcoil is a capstan system that is used when steel band fabricated. Exist for example in production lines their steel band should be annealed. Our goal with this work is to come up with a completed production basis on a Camcoil for heavy industry. The basis should contain calculations, 3D-constructions, drawings and cost proposal on manufacturing and detail purchase.Demands on this project:1.
Kvalitet på vägdata : inventering av skogsbilvägars standard samt jämförelser med lokal bedömning och SNVDB.
During 2006 SNVDB (the national road data base for forestry) is being introduced to Holmen Skog. This data base contains all information about Holmen Skogs road systems. The information will then be used in different kinds of optimisation models which only produce correct and reliable results if the input data are of the adequate quality.
Today there are reasons to believe that road data is of various qualities. The forest roads are often in a bad condition and have to be improved before a planned harvest. The cost of maintenance and construction of new roads is a large part of the total harvesting cost.
The Sims : En studie om skapandet av karaktärer ur ett genusperspektiv
Todays gaming habits between women and men depends on the age range. Both sexes are playing but how do they create a character when they have free hands? Are there any differences from a gender perspective? The main purpose is to answer the question: How does women and men create characters in the computergame The Sims? By looking at the result of four women and four mens created character and then interviewing them for profound information, we have received data to answer those questions for our study. Data has shown that the men were less personal when they created a character, used more imagination and took less time to create the character. The majority of the women created themselfs or part of themselfs and took more time on details..
Interactions between some plant-parasitic nematodes and Rhizoctonia solani in potato fields
The pathogenic fungus Rhizoctonia solani causes major economic losses for potato producers in Sweden. The producers, as well as advisors, have reported possible increases in severity of R. solani when free-living plant parasitic nematodes are present and active. There are several examples in the literature of interactions between pathogens where one, or both species, support or increase the damage made by the other organism. These complexes are important to investigate and to be able to forecast, since even low incidences of fungi or nematodes may result in an interaction of significance.
Licens för frihet? : ? en kritisk diskursanalys av fri programvara
Studien behandlar ämnet fri programvara utifrån ett diskursanalytiskt perspektiv. Texter och tal av Richard M.Stallman, grundaren av Free Software Foundation (FSF), ligger i fokus för studien. FSF är en rörelse som har isyfte att göra och kämpa för fri programvara. Detta innebär uttryckligen en kritik mot programvara som är ofrieller proprietär. Studien visar på tre olika diskurser som är betydelsefulla för fri programvara; frihetsdiskursen,maktdiskursen och etikdiskursen.

Provinssnickarens poesi
I have studied and worked with various joints and interpreted twenty-six of them to small models. I then placed these into a template so that I could record the properties and their expressions.The protocol show what the joint looks like, and what its strengths and weaknesses are. Moreover, they are translated into a freer text, a poem, that describes what I think and feel about the joint.Based on the protocols, I have selected a number of joints which I then interpret into furniture. I have chosen to move forward in slightly different ways with different joints. Sometimes it is the expression of the joint that has given birth to a new idea, it may be the poem itself that led me on to a form, combinations of joints and that I found interesting, and so on.My interpretations are then further translated into new poems that describe what I see and what I feel when I assemble and disassemble each piece of furniture..
Demokrati, ett uppdrag för skolan : En implementeringssudie angående demokratiuppdraget i skolan
The current study sought to examine if post-produced semantic memory cues are a good aid for memory recall. It also focused on remembering units with a meaning, instead of just remembering lists of words. In the current study a factual text was used where the participants were tasked with recalling as much information as possible either with the aid of cues (keywords written by the participants themselfs), computer with Internet or no aids at all. The results showed that keywords are significantly better for memory recall. The results were discussed in regards to modern models describing semantic memory.
Utveckling av metod för retrospektiv bestämning av absorberad dos i korall medelst elektronspinnresonans
This diploma work was performed at the department for radiation physics at the Health University in Linköping. Its aim was to develop a method to retrospectively quantify the absorbed dose in coral. Coral is a material which suites well as a retrospective dosimeter because when exposed to radioactivity its induced free radicals are stable in time. The number of radicals is proportional to the accumulated dose so the dose can be calculated by quantifying the radicals. Therefore, coral can tell us something about the past environment and also be used in dating purposes.A young, modern coral from the Red Sea was studied and also a fossil one which I was given from the Natural History Museum in Stockholm.
