Ekonomiska konsekvenser för skogsbruket vid avsättning av mark för viltvårds- och jaktändamål : en fallstudie på Svenska Jägareförbundets fastighet Öster Malma
The value of game for hunting from a social economic viewpoint is an interesting topic
that is currently being investigated in a Swedish research program. The amount of
damages that the game stocks cause to the forestry is, and has been in focus for a longer
period of time. Something that I saw as missing was an investigation of how much an
active game keeping measure might cost in lost incomes for forestry in terms of reduced
acreage for forest production.
This question was the foundation for this investigation, which purpose is to give
interested persons with decent knowledge of forestry an example of how cost estimation
for forestry resembling the example that is studied can look like.
The measures that has been taken is a felling of forest in different ages on both sides of
a forest dirt road to create increased asset of forage for the game, and at the same time
give hunters that have their post along the dirt road a better chance of seeing passing
animals early and increasing the possibility to shoot good shots. The area, which is a
part of The Swedish Association for Hunting and Wildlife Management estate Öster
Malma, is also used as an example for guests who wish to learn more about managing
ungulates. These guests have now got the opportunity to get information on how big the
costs are for the measures that have been taken.
The main conclusions of this work is that changed timber prices and foremost a change
of interest rate makes big differences on the result of the Calculations.
Effektivare energianvändning på Totebo AB
The main goal with this thesis report was to come up with ideas of how to make the use of energy more effective and thus save money for the company.First a survey was made to find out where and how the energy consumers were divided within the company. The results were then used in Calculations to find out how much money that could be saved and how long it would take to get back the investments.There is a big potential in saving money by recovering heat from the UV-lamps with a heat exchanger. It would also even out the pressure in the factory which is a source to heat loss and a cause for discomfort amongst the employees. It?s possible to save 105 000 kr in a year and the money needed for the investments is 600 000 kr.By using the recovery air more effectively the company could save up to 250 000 kr a year in lowered heat purchases, but this would require the use of automatic dampers.If you reschedule the running times for the wood chipper and invest in some kind of load management, for example Sydkraft?s ?Energidirigent? you can save at least 42 000 kr.
Byggnads- och investeringskostnader : Robotmjölkning eller konventionell mjölkning?
This project is based on my fathers farm which lays outside Löberöd, twenty kilometres south
of Eslöv in Skåne.
While my family for some time have thought about building a new milkingstable with
AMS(Automatic milking system) I decided to compare the AMS with a conventional
milkingstable. We are abit concerned about how many cows we should have in the new
stable. Because of that I calculated with two different number of cows.
I have compared three different types of milking stables:
One alternative is 180 cows milked in a double eigth hearing bone milking stable.
The second alternative is 128 cows milked with two DeLaval VMS-robots.
The third alternative is 171 cows milked with three DeLaval VMS-robots.
One salesman from DeLaval and one salesman from A-betong helped me to get marketprices
on the milkingrobots, building, ventilation and prices on all the concrete. In all the costs
labour is included.
The rest of the costs are calculated in a softwareprogram called K-data 03 which is a program
with predicted costs. The calulations from the program showed that the price in the milkingpit
system was 51 000 sek per cow.
Konstruktion av steghållare till brandbilar
High demands are set on all equipment used in emergency service work, where small margins can be the distinguishing factor between life and death during a rescue operation. It is important that tools such as ladders quickly and easily can be dismounted from a vehicle and still satisfy the regulatory requirements for securing loads during transport. The existing solution for getting ladders down from the roof of a fire engine requires a large manual effort from the user in an ergonomically unsound posture.In this degree project a new ladder holder is developed with focus on the user to solve the ergonomic problems and at the same time create a more compact design that can be adapted to several different types of ladders. After an initial pre-study with user-interviews and measurement of forces and distances a set of requirements was formulated that came to govern the project's direction. Creative methods were used to generate concepts that improved the function and through design solutions, Calculations and testing in CAD a base for manufacturing of a new product was created.The result is a completely new type of ladder holder that minimizes the user's manual effort and simplifies the securing of ladders in the holder.
Val av energisystem för en hållbar stadsdel : En fallstudie av Östra Sala backe
Uppsala County has ambitious environmental aims for the planned residential area inÖstra Sala backe. In this thesis different energy sources have been evaluated todetermine which system that would be most favorable given currently availableinformation about the project. Planned energy usage has been divided into tap waterheating, space heating and power. Three base case scenarios were made with districtheating, small scale bio fuel and heat pump. Solar power and solar heating were thensimulated and the production from the two could individually be deducted from theenergy need in the base cases, constituting 9 different scenarios.
Omvärlden - Oftare obevakad än bevakad? : En kvantitativ studie av omvärldsbevakning bland Svenska Golfklubbar
In the global and rapidly changing society Environmental scanning is becoming a more and more important tool. Today it is not the availability of information that controls an organizations behavior, but the information that the organization chooses to absorb. This is the case for a multinational cooperation as well as for the local golf club. Swedish golf clubs have during the last 100 years had an amazing development and today there are almost 600 000 registered Swedish golf players. The development has however stopped and even declined some during the last couple of years.
Energianalys mellan programmen IES (Integrated Environmental Solutions) och Enorm
An increase interest of new methods and tools has begun to grow in the real estate business, this new trend causes an increase in new programs that aim to simplify processes of energy-efficiency and environmental issues.After consulting with Björn Alsmark from Bjerking AB, an architect and engineering company, we made a decision that the Degree Project is going to examine the program IES (Integrated Environmental Solutions) with some integrations from Revit Architecture application.To be able to examine IES, we got access to a completed project from Bjerking. The project is a nursery school in Uppsala. An application has been handed in from Bjerking to make this project to a Green Building-certificated project. According to Bjerking own Calculations (with the energy-calculation program Enorm), the consumption of energy of the nursery school is 48 percent lesser than required by BBR.An evaluation of IES and Enorm has been made with an aim to compare these two programs and find out if IES is an appropriate program to replace Enorm. Does Enorm or IES come up to BBR´s recommendations?The Degree Project cover 15 ECT, that required several adjusting and delimitations, and the study sketch ended with a literature study.After finishing the study sketch the modeling of the nursery school began.
Trycksättning och dimensionering av brandhiss för berganläggning
This thesis deals with the design of a combinated rescue-, personal-, and firefighting elevator for a nuclear waste storage facility to be constructed by the client SKB, Svensk Kärnbränslehantering AB. SKB:s mission is to dispose of all nuclear waste from all swedish nuclear power plants. The storage facility will be built in the rock 450 m under the surface and will consist of several kilometers of tunnel where capsules containing the nuclear waste will be placed. It will also hold a central area which contains spaces necessary for the operation and construction of the facility, such as elevator hall, storage hall etc. The facility will have two ways of access: a vehicle ramp and an elevator shaft.
Lönsamhetskalkyl för produktion av gran på markavvattnad och askgödslad myrmark
In Sweden there are about 4 million hectares of bare peat (mire). This land has great potential to be transformed into productive forest land, provided drainage is carried out and, in some cases, even fertilization with ashes. Drainage of mires is necessary because the high groundwater table prevents trees from growing due to reduced oxygen availability. Some of the key nutrients that trees need to grow appear in too small quantities in mires, especially potassium (K) and phosphorus (P). Ash from the combustion of biomass contains these elements and is therefore suitable as a fertilizer.
Bostadssektorns koldioxidutsläpp
Energy is an important issue in the current world which significantly affects sustainability and development. Energy generation and use are major sources of CO2 emissions which is one of the most important driving factors in global climate changes. The amount of energy used in house hold section can lead to estimation of the amount of CO2 emitted within this section which subsequently would be a ground to better management and maintaining a sustainable society. This study which is a bachelor?s project in sustainable energy, deals with estimation of CO2 emission from different types of residential houses in Sweden. An extensive literature review on energy use in Sweden by different residential sectors has been conducted.
Underlag för BREEAM-certifiering : Kristianstad Nya Galleria
The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.
Biomekanisk analys av patientlyft i team
Background: The majority of the occupational accidents and work-related diseases at Swedish workplaces occur due to poor ergonomics during lifts and transportation of objects. The most common consequence of poor ergonomic conditions is low back pain (LBP) and the risk of developing LBP increases as the mechanical loading on the intervertebral disks grows. This study has investigated the biomechanical loading in the low back during two different types of patient lifts. The first lift (lift A) is developed by Modern Arbetsteknik (MA) and the second lift (lift B) is a common lifting technique among care workers. Objectives: The aim of the study was to identify any advantages or disadvantages with MA?s lift, regarding shear and compression forces in the L5/S1 disc.
Värmeförluster vid utvändigt placerade ventilationssystem
To be able to handle tomorrows need for limited energy consumption we need to reduce our use of energy. The building sector stands for around 40 % of all energy consumption in the society. The government has put up a goal to reduce the energy consumption in our buildings with 20 % by year 2020 and 50 % by year 2050 compared with year 1995. To be able to do reach that goal we need a more energy efficient building stock.The main part of the energy used in our buildings is used for space heating. By installing ventilation systems with heat recovery on the exhaust air it is possible to use the heat-energy in the exhaust air to warm up the incoming air.
Analys av framtida potential för virkesköp från privata skogsägare i Västerbottens län : beslutsunderlag för virkesköpsstrategier
This study was conducted on behalf of SCA forest AB, Västerbottens forest administration. Timber procurement from non-industrial private forest owners has become an increasingly important part of SCA:s wood supply. The objectives of this study was to report the current forest conditions in the private forests in the county of Västerbotten, analyse the potential for procurement of wood from private forest owners, and provide a basis for decisions on future strategies for timber procurement from private owners.Material and data have been collected from different sources, mainly from Swedish National Forest Inventory and SKA-VB08. This material was the basis for the analysis and Calculations performed with the Heureka application PlanWise. This study area was divided into six different analytical areas (Coastal south, Coastal middle, Lycksele, Inland south, Inland north, Skellefteå), where each area of analysis is represented by a number of municipalities.In this study, two scenarios were specified; one describing the current forest management with current harvesting levels and the effects of these assumptions, the second to illuminate what potential there is for future timber harvesting.
Cykelolyckor i korsningar : Hur kan trafiksäkerheten förbättras?
Stockholm city has recently raised its ambitions for bicycle traffic, the goal is to achieve a larger andsafer bicycle traffic. But cyclists are more vulnerable on the roads than other vehicle users because of the lack of protection. This means that a large proportion of road safety for cyclists is based on the design of the traffic environment. Since most serious bicycle accidents are those that occur in conflict with motor vehicles, and the majority of these accidents occur at intersections, these areas are of great importance forcyclist?s safety.The purpose of this paper is to highlight bicycle accidents at intersections and to suggest improvements in three accident-prone junctions in Stockholm. This is achieved by the study of accident statistics, literature and finally three case studies.The literature study focused on cyclists, traffic safety and traffic safety measures.
