Development of a method for determination of pesticide residues in honey using liquid chromatography tandem mass spectrometry
Honey is a product that may contain pesticide residues due to contamination from bees pollinating various plants as well as elimination of vermin inside the hive. Different methods are needed for analysis of pesticides, since the term includes a wide range of different substances. National Food Administration lacks a validated method for determination and quantification of pesticides in honey using liquid chromatography tandem mass spectrometry, LC-MS/MS. The technique is especially important in analysis of polar and non-volatile pesticides, where gas chromatography is not functioning optimally. After investigating what pesticides could be found in honey produced in Sweden, a number of four pesticides suitable for analysis with LC-MS/MS was compiled; boscalid, impidacloprid, tau-fluvalinate and thiacloprid.
Faror i varor : En studie av unga vuxnas medvetenhet om kemikalier i hygienprodukter och kosmetika
Chemicals are everywhere in todays society, in humans, animals as well as nature, and they are difficult to avoid. The chemical industry is regarded to be the fastest growing industrial sector, accounting for ten percent of the global economy. A large amount of chemicals are used to produce hygiene products and cosmetics, products that in Sweden only are consumed in quantities of 110 tons per day. Researchers find it increasingly difficult to determine which chemicals that are dangerous and which that are safe, and how they might affect us in the long run. Correlations have been found between chemicals, diseases and other health effects such as cancer, allergies, reproductive and endocrine disorders.
Bandtraktorer - något för framtiden? : en ekonomisk jämförelse mellan hjul- och bandtraktorer
AbstractMycotoxins are secondary metabolites produced by filamentous fungi. Moulds producing mycotoxins grow on various crops that are used as horse feeds. Since the treatments of mycotoxin poisoned horses are limited it is important to prevent production of mycotoxins in feed. The major mycotoxin producing moulds in horse feeds are Fusarium spp., Penicillium spp. and Aspergillus spp.
Kommunikationens betydelse för ett lyckat outsourcingprojekt
Today it is mainly small and medium sized companies that choose to outsource parts of their ITdepartment in order to increase and become great. It is becoming increasingly common forcompanies to take the help of competent suppliers so that they then can focus on their own corebusiness. These companies are taking advantage of modern methods to support systemdevelopment by outsourcing to other countries such as India. Choosing to outsource to othercountries poses new challenges for companies when they meet both cultural and organizationaldifferences. It requires a lot of time and planning and clear communication in order to developand reach the goal.
Direct-EGR tillämpat på HCCI
The Homogeneous Charge Compression Ignition (HCCI) engine is promising in terms of lowNOx, low particulates and high efficiency. Due to its homogeneous charge, where thecombustion starts almost simultaneously from a number of points in the combustion chamber,only lean mixtures are possible to burn because of the resulting rapid combustion, which is muchfaster than the combustion in an SI-engine or a diesel engine. When richer mixtures are used thecombustion will start earlier and also be more violent.To phase the combustion later and lower the combustion speed, external cooled EGR can beused. The EGR-system used in this thesis uses a divided exhaust channel where one channel andits corresponding valve are used only for transporting EGR back to the intake system.Consequently the EGR-valve is connected to the intake pressure. This system is called Direct-EGR (D-EGR).Engine tests verified that the CA50 indeed is phased later when cooled EGR is used.

Driftkostnadsanalys i väginvesteringsprojekt
During its lifetime, a road goes through a number of different stages; pre-study,inquiry of the road, work plan, documenting stage, building stage and operatingstage. The operating stage is the one that takes the longest time and costs themost. Those have a tendency of becoming unnecessarily high because the projectengineers don?t always take the management and maintenance prerequisites intoconditions.To decrease the management and maintenance costs, the Swedish RoadAdministration SouthEast has been in need of a work procedure that makes theroaddesign engineers take the management and maintenance of the road intoconsideration. This shall be achieved by a checklist where the most commondesigns that lead to increased management- and maintenance costs are compiledand listed.Through interviews with project leaders in management, the most commonproblems have been identified, analyzed and summarized under the headlineswinter-road, vegetation, road equipment and road designs.To elucidate the problem from several points of view, interviews wereimplemented with project leaders in investment and roaddesign engineers.
Värmebehandlat trä ? att inhämta synpunkter i produktutvecklingens tidiga fas :
This study is a part of a Swedish research and development project that is about heat-treated wood and is led by the Swedish University of Agricultural Sciences and Luleå University of Technology. Products that are heat-treated already exists on the market, foremost the Finnish brand ThermoWood®, bur the project group want to find out if it would be possible to start a Swedish production with somewhat different applications than what is common today.
The heat-treated wood has many attributes that have changed in the heating process. It becomes more biologically durable, it gains stability in form and dimensions and it becomes darker and looses several unwanted extractives such as resin. Disadvantages that can be mentioned are that the wood becomes fragile and the strength properties changes.
My main purpose with this study is to look into customer involvement in the early phase
of product development. I also want to find out if the customers I interview think that the product is worth working with, which means start a Swedish production.
SARS
SARS [Severe Acute Respiratory Syndrome] penetrated China in spring of 2003, created havoc in the social society, exposed weaknesses within the political system and pushed the nation towards a crisis of confidence. At the same time the crisis revitalised the Party's position, brought people from different social stratum together and had a beneficial impact on the populace's knowledge on health related issues.What makes the SARS crisis in China interesting for further and deeper investigation is the method it chose to respond to its national crisis. They plan of response was indeed a retrogression back to "older" times, using methods and propaganda very much like those used during Mao Zedong and later Deng Xiaoping. The first step of response was denial and cover up of the real situation, which quickly turned to unprecedented transparency, as the magnitude of SARS became known. The Party and the government were quick to proclaim themselves as the bearer of the key knowledge and information on how to best fight the disease, this in sharp contrast to the political trend of more co-operation between the private and public sector and political transparency.

To be able to find the problems, create a common knowledge of which these are and eliminate them the production department of Sectra Mamea needs to visualize certainKey Performance Indicators (KPI) in the organization.
Att arbeta med webbaserad sfi-undervisning : Sfi-elevers syn på internetbaserad undervisning som komplement till lärarledda lektioner
What are the basic thoughts formulated in the Heraclitean fragments? A cosmology, a philosophy of nature, the idea that all can be reduced to a single substance? There is always a risk that Heraclitus is fitted into a thought pattern he doesn?t belong to, if we ? from our present horizon ? focus on continuity in an attempt to frame his thinking as part of an overall progress, running from the so-called pre-Socratics to Aristotle, in the history of philosophy. If we picture the dawn of Western civilization as an early development of scientific thinking, built on a gradual and continuous growth of knowledge, we will easily go astray as we try to discover the Greek origins of philosophy. Assuming, for example, that the readings of Heraclitus as a natural philosopher have come to a dead end, can we approach the fragments from a different angle?The aim of this paper is not to give a systematized reading of all the remaining fragments of Heraclitus, but neither to necessarily contradict the various interpretations that emphasise how these shattered remains reflect a coherent philosophy.

Finansiering av vindkraft : fallstudie av Lau Vind AB
The wind power increase of Gotland as well as other parts of Sweden during the last ten year period has meant that this renewable energy source has increased its share over other fossil sources. The year of 2011 became the first when the wind power produced more energy than an average nuclear reactor. Now that wind power is in an expansive phase, the land issue will be of great interest. Land with good wind resources will be of interest to wind energy developers. The problems that this essay is based on are; how can landowners altering the economic conditions at a wind power establishment? What opportunities and obstacles exist for landowners who choose to set up wind power on their land? The purpose of this essay is to highlight the economic conditions that exist for landowners for the establishment of wind farms, with regard to compensation for the leasing and return on invested capital.
