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.

Hybridlärkens tillväxt i Snogeholm : hur påverkas produktionen i blandbestånd jämfört med trädslagsrena bestånd?

The hybrid larch (Larix x eurolepis Henry) is a fast growing tree species and was introduced in Sweden for about 50 years ago. The high growth and expected resistance to diseases are probably the main reasons of introducing the tree species into the Swedish forests. The purpose of this thesis was to document the production of hybrid larch planted in the Snogeholm landscape laboratory and to compare the production in the pure hybrid larch stand with the mixture together with pedunculate oak (Quercus robur). The data collection in Snogeholm since the establishment has been carried out by the Swedish University of Agricultural Science (SLU). The fieldwork for the thesis was carried out in 3 stands, containing hybrid larch, pedunculate oak and a mixture of hybrid larch and pedunculate oak, in order to be able to compare the total stand production of the areas. The results show that the total production of hybrid larch in the mixed stand only is 35 % compared with the total production of hybrid larch in the pure stand. Therefore, the hypothesis that the total production of hybrid larch is equal to the planted mixture with pedunculate oak was rejected. The other hypothesis that the total production of a 2 hectare large stand containing a mixture of hybrid larch and pedunculate oak would be greater than the total production of two pure stands of 1 hectare containing hybrid larch and oak each was also rejected. In the studied case the total production was 45 % greater if hybrid larch and pedunculate oak was planted in pure stands. The results from the case-study only indicate that the total production of hybrid larch and oak under the investigated conditions can be higher when planting the two species in pure stands compared with a mixture of the two species.

Elevers syn på klimatfrågan : Klimatundervsiningen i skolan

The aim of this study is to find out in which way the education about climate in school is taught and how the students experience the world situation today. There are various theories about the greenhouse effect and its origin and these theories should be addressed to ensure that students get a broader understanding of how climate change occurs. This includes the natural phenomena and also the human impact on climate change. Students in school are a source of concern that only human are the cause of global warming, and know little or almost nothing about the natural phenomena of global warming.  I will mention what has emphasized in the national steering documents in the case of environmental education at school.I have used a qualitative method, where interviews and document analysis were used as techniques. The interviews took place with five students in ninth grade and with three science teachers in the same school..

Framgångsfaktorer och hinder med Lean produktion i Kina

AbstractLean production has become one common concept within industries to make the work more effective and to meet today?s hard competition. A challenge for Chinese production is the threat from new low cost countries. It will become very difficult to succeed to produce to a lower cost than these countries; this led to that Chinese companies must develop new strategies, according to Lee and Zhou (2000). This will put China in front of new challenges and new strategies can be needed to retain their strong competitive advantages.

Implementering av Lean genom TAK och SMED

This graduation work is a result of implementing Lean Production using OEE and SMED at Enics Sweden AB in Malmö. Enics doesn?t have an established improvement concept and therefore should this work serve as an introduction to possibly start with Lean Production. A result in this report is that an OEE value has been identified within a common order at Enics. Other results are that an implementation of a Lean-board has been implemented and furthermore, within SMED, a flag that indicates changeover..

Förbättring av utnyttjandegrad i robotcell

When a company in the manufactory industry makes costly investments, it's important that these are used as much as possible. The company in this case claims that their invested robot cell, with CNC machine isn't used enough. The questions here are: How can we improve the use of the robot cell? Which products are appropriate for the production in the robot cell? As a method to come to a conclusion, an analysis has been made over the manufactured products. And also interviews with machine operators and the production management.

Att använda ett undersökande arbetssätt i NO-undervisningen : En jämförelse mellan kommunal- och resursskola

The purpose of this study is to compare an inquiry-based teaching method for natural sciences in municipal schools and special education and to find out if this way of teaching may be helpful when working with students with Attention Deficit Hyperactivity Disorder (ADHD).The Swedish national curriculum of 2011 states that teaching methods should be fitted to every student?s needs and preconditions. The implication of this is very important for all students, especially for children with special needs. The theoretical framework that has been applied as a foundation for this study is Vygotskijs "Zone of Proximal Development" and Deweys "Learning by Doing". The method applied for the study is a semi structured interview and five teachers where interviewed.The result of the study shows that teachers with a higher education in natural sciences are more confident with regards to teaching natural sciences and the application of the inquiry-based way of teaching.

Vaktelproduktion för ägg och kött

The aim of this study is to review the commercial quail production for eggs and meat in the world. Another aim is to review the potential for increased production. Globally the quail production is very small, except in China where it is the second largest poultry industry. The production globally is small despite the quail's rapid growth, early sexual maturity and its high feed efficiency. The quail is also used as a laboratory animal and can be reared to be released in hunting areas.

?Vård i annans hem? - användning av arbetsmaterialet i Huddinge kommuns hemtjänst/boendestöd och personlig assistans

AbstractThe importance of good construction planning affects the final costs of the production and the timing of the project. Planning for building projects has been studied with the aim of identifying how three week planning appears in the construction industry today.A case study has been conducted in Navisworks Simulate to assess whether the software is suitable to connect the task schedule with the BIM model to create a 4D model. 4D models are used for performing 4D construction simulation to visualize the project. In order to use the benefits of the model, investment in equipment and software is required. This means higher costs for the companies.

Utvärdering av substrat för biogasproduktion

The purpose of this study was to evaluate the different substrates that enter the digestion on Sundet wastewater treatment plant for production of biogas.This work have done an analysis of data about the biogasproduction from January 2012 to feburari 2013, this showed that the food substrates has a greater gas production than internal sludge.Through laboratory test the VS, TS and COD values for all the substrates used in the biogas production could be determinded. But the COD-method was less optimal for analysis of fat and food, therefore it optimized the method for fat but due to time constraints, this could not be done on the food substrates..

Opera i Stockholm : Stadsgårdskajen

The report is about efficiency of a current production group where there is no clear production flow and there are some buffers between the operations. The efficiency is done with the help of a tool that is calledWork process of flow production which is used by Atlas Copco CTO. The most obviously results are that the lead time drops from 25 hours to 425 minutes and that the balancing loss decreases from 85 % to 8 %. The report focus on decreasing transports, decreasing buffers, more reliability in lead time and quality. And a more stimulating labour content for the workers is another result..

Ståndortsanpassning och produktionspotential för björk i Gävleborgs län

Large amounts of birch-timber are imported to Sweden, from particularly the Baltic States, since the domestic production can?t support the pulp industry. The goal of this study was to show the potential of birch and the area?s most suitable for birch production. The study was limited to Gävleborg County. Using site characteristics, site index (SI) for birch was estimated on all National Forest Inventory plots in Gävleborg County.

Multikriterieanalys av potentiella konflikter vid markanvändningsplanering - Naturstenbrytning i Lysekils kommun

The purpose of the essay Multi criteria analysis of potential conflicts concerning land use planning - natural stone mining in Lysekil municipal is to study possibilities and limitations in GIS based multi criteria analysis as a tool for land use planning. How GIS based multi criteria analysis can be implemented to localize potential conflict areas between natural stone mining and other land use activities and what advantages and disadvantages the method holds are the main issues of this study. The essay studies these questions through a case study, concerning the geographical area of Lysekil municipal in western Sweden and problematizes the interest of natural stone mining in relation to other land use interests. A literature study was carried through, concerning multi criteria analysis and planning. After collecting and processing of data the multi criteria analysis could be implemented in the ArcGIS tool Weighted Sum.

Hur inverkar olika andel vallfoder i utfodringen på produktion, hälsa och beteende hos mjölkkor? :

Cows are ruminants and they need fibers in their feed and sufficient eating time to function psychologically and physiologically. Many of our cows don?t get enough forage and too much concentrates, which given in the wrong way may cause health and behavior problems. Too much concentrates at once makes the pH in the rumen sink and this may cause decreased fiber utilization since the microbes in the rumen are negatively affected by this. The cow may also get serious problems such as laminitis and abomasal dislocation.

Hur mår svensk filmmusik? : En kvalitativ studie av svenska filmkomposito?rers fo?rutsa?ttningar i det nutida produktionsklimatet

This thesis examines Swedish composers' modes of work and production within the Swedish film industry. It starts off with a historical overview treating live music in early silent film, the conversion to sound and the Swedish production climate until present time. The analysis consists of contemporary empirical studies; interviews with people writing music for film, TV and commercials. The musician's perspective is in focus but directors and other film workers are heard as well. The situation for female composers in a male-dominated industry is also discussed.
