Summary The leaf beetles, Lilioceris lilii and L. merdigera have existed in Asia, Europe and in North Africa for a long time, but have become much more abundant the last twenty-five years. Even North America has been affected during the last years. The purpose of this investigation of Lilioceris species in Sweden, is to give advice to gardeners, which type of control measures is the most effective in order to restrict their damage to lilies. Lilioceris species overwinter normally as pupae in the soil under the host or close by. Literature and contact with advisors have described the life cycle and spreading of Lilioceris. Under favourable conditions these leaf beetles have two generations/year in the south of Sweden. Both the adults and the larva eat the foliage, and by strong attacks even flowers can be eaten and only the stem is remaining. My own observations include different treatments of both lily foliage and of the leaf beetle.

Testing has always been an important task in the scope of software quality. Though it has never been as much appreciated within the management of the organisations as the software development has. However testing is becoming more attractive within organisations because it becomes more evident how much money working systems saves in contrast to defect ones. A tester often use testing tools to simplify the work progress. There are a lot of tools nowadays but not many evaluating models which helps the tester to know which one to recommend.

In this study, the pre-tension force in an insert screw connection are examined in order to establish a greater understanding of the system and to facilitate the process of making new metal cutting tools. Certain especially significant design variables such as the offset, the length of the contact thread and the shank length above the threaded hole, are selected to be closely examined. A comparison of the influence on the pre-tension force between threaded holes made with a worn, versus new, threading tool is also involved in the experiment. The study is limited to handling the screw sizes M2,5 and M3,5. The results show that a regression model, with good approximation, can be fitted to the measured values.

The European Council agreed in 2008 on a climate and energy package to combat global warming. This package is valid for each EU member country and means that greenhouse gas emissions must fall by at least 20% and the EU's energy use to 20%, consisting of Renewable Energy in 2020. The Swedish Government has set stringent climate and energy with the intention to set an example for the rest of Europe. For example, renewable energy sources account for at least 50% of energy use and our climate emissions to fall by 40% by 2020. A combination of these goals and a steadily rising oil price has led to an increased demand for wood fuel in the form of such branches and tops.

The name of the study means ?The short arm - a study in diversity and arm?s length in the cultural collaboration model?. Right now there is a reform in the Swedish cultural administration where the responsibility for handing out state funds and grants to cultural organizations is changing from the state government to the local regional governments. The purpose of this study is to map the organisational changes caused by the reform and investigate how this affects the regional policies concerning cultural diversity and the arm?s length principle.

AbstractEffective January 1, 2005 publicly listed companies were obliged to adopt a new financialreporting standard (IFRS/IAS). The objective of IFRS/IAS was to increase transparency andcomparability in financial reports between companies. The authors have chosen to write aboutIAS 40 where the accounting treatment for investment property and related disclosurerequirements are regulated.The purpose of this thesis is to investigate potential effects of valuation of investmentproperty at fair market value for real estate companies at times when market price decreasesand to investigate what an acceptable difference for the valuation could be.To fulfil this purpose the authors have chosen a qualitative method interviewing accountants,property analysts and a credit analyst to obtain a deeper understanding of the problem. Basedata for the thesis have been collected during meetings, telephone interviews and e-mails.Additional data was collected from public available sources such as the internet, relevantprofessional magazines and professional newsletters. The authors have designed a modelshowing how Income and Balance Sheet statements are influenced by changed valuation ofinvestment property.

Warehouses are a key aspect of modern supply chains and play a vital role in the success or failure of businesses today. Figures from the USA indicate that the capital- and operating costs of warehouses represent about 22 % of a company?s logistics costs while figures from Europe indicate 25 % (Baker & Canessa, 2009). Because warehousing is such an important function within a company, the authors chose to focus on this in their thesis. The purpose of this thesis has been to examine the significance of a Warehouse Management System (WMS) and item identification with attention to logistic efficiency.

Hospital Mergers have been proved to be troublesome, the most crucial ingredient is believed tobe the participation of members of the organization on all levels. When the hospital mergerbetween the hospital of Malmö and the hospital of Lund is a fact, it seems clear that knowledgeabout managing motivation is important. The knowledge could also lead to increased possibilitiesto improve support for motivation where needed at the hospital.I have through a literature review created a descriptive model of the theoretical view onmotivational factors for participation in change and their relationships. The theoretical modelwhere then tested in a empirical study in which additional data created a more true model of themotivation on participation at the hospital.The findings of the study show how the descriptive model illustrates how the twodifferent departments both work with a empowering philosophy that have built in properties thatenable the employees to gain more motivation. The model also underline the importance of thecommunication role to enlighten the employee in what, where, when and why the change takesplace.

This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

The quality of bread wheat is a large subject to study. The quality rests on two legs. The first one is the inheritance of specific characters, which can be influenced through plant breeding and type of cultivar. The other one is the environmental influences, such as crop rotation, nutrition, harvest and storage. The latter factors are possibly to affect through cultivation practices, while other factors are not possible to influence on for the grower, such as seasonal changes of weather and the soil content.

Sitka spruce (Picea sitchensis) is not considered to be a native species to Swedish forests. It´s origin is the pacific coast of Northern America, an area that is dominated by a coastal climate which makes it likely to believe that it would be well suited for growing in the south-west of Sweden. This study aims to investigate the gain in production that can be reached by growing sitka spruce instead of Norway spruce (Picea abies) in the county of Halland. A regression model based on data from forest experiments was produced to explain the gain in production. This model was based on elevation and annual precipitation. The model was then used to create a map layer in arcGIS that shows the gain of volume in comparison to Norway spruce in percent. An analysis was carried out to find what share of the forestland in Halland county that fell into four different classes of production gain.

The Swedish consumption of lamb a increasing, and today we yearly eat a kilo of lamb per person each year. As a consequence the Swedish degree of self production according to lamb is steadily decreasing, and is today about 39 %.Today Swedish Meats is now cooperating with the Swedish lamb breeders organisation to raise that percentage. At the same time the European Union presents a new agricultural reform, the MTR (Mid Term Review). The shape of this new reform is not yet fully known, but the general policy has been more or less outlined. The new reform is split into three propositions: the farm model, the regional model and the mixed model.

Eco Log AB i Söderhamn är en tillverkare av skogsmaskiner. De tillverkar både skotare och skördare. På deras skördare sitter fyra pendelarmar som ersätter hjulupphängningen på fordonet. Dessa motverkar att fordonet lutar vid körning i sluttningar. Varje pendelarm drivs av en hydraulkolv som justerar nivelleringen.Då inga beräkningar med avseende på utmattning och livslängd genomförts sedan en omkonstruktion av pendelarmarna är det nödvändigt att analysera och utvärdera pendelarmarna.

A real option model is developed to examine the crucial factors affecting the agricultural firms? decision to quit the production and rent out the land to a company building a PV power plant. The public policies in support of investments in renewable energies have created the conditions for a market regarding investments in PV installations in agricultural areas.The decision to switch offers to the agricultural firm and to society several economical, social and environmental benefits, representing sustainability. However, PV installations in agricultural areas require the allocation of a certain land area. By assigning a part of land to PV installations, thereby the area of land allocated to agricultural production decreases.

Syftet med vår uppsats var att med hjälp av Model Confidence Set (MCS) finna de bättre presterande modellerna bland de mest ?kända? och undervisade volatilitetsmodellerna. Vidare har vi även rankat dessa modeller inbördes. Eftersom prognoser om volatiliteten är mycket viktigt vid prissättningen på derivat, i detta fall ett räntederivat, är ämnet ständigt intressant. Med Model Confidence Set fann vi ett set av bättre presterande modeller utifrån vårt urval av ursprungliga modeller.
