Olfactory responses of the parasitic wasp, Trybliographa rapae (Hymenoptera: Figitidae)
Delia flies (Diptera: Anthomyiidae) are economically important pests in several horticultural crops. The control is commonly relying on chemical insecticides, though there are possibilities with biological control from the natural enemies in the field. An important natural enemy is the parasitic wasp, Trybliographa rapae Westwood (Hymenoptera: Figitidae) that lays eggs in the Delia fly larvae. The parasitoid larva and the host larva have a parallel development until the host dies within its puparium and an adult parasitoid emerges.
The aim of this thesis was to understand the attraction to host- and food-associated plant volatiles of T. rapae, in order to enhance the effectiveness of the parasitic wasp as a biological control agent.
Modell för att jobba med användbarhet i ett affärssystem
Det är viktigt att bygga affärssystem med hög användbarhet, så att användarna ska kunna arbeta med affärssystemet så effektivt som möjligt.

The bioavailability of soluble oxalates in stir-fried silver beet leaves
The prevailing food and energy crisis of the world, due to the declining reserves of fossil energy and a never ending rise of consumption, forces us to look into new fields to supply our energy demand. The boom of bio energy is criticized, as food crops are used to provide biodiesel and ethanol and the volumes are ridiculously small to supply world demand. Algae are one of the world?s oldest life forms and exist in many different phyla, providing a great variety to choose from, for different purposes. Cultivating microalgae offer a way to produce energy at great volumes without competing with food production and at the same time the algae offer a way to use our expensive nutrients in a more efficient way, besides this the algae are carbon dioxide neutral since their carbon source can be supplied by the atmosphere and the additional energy required can be supplied by algal oil or other renewable sources.
Sexuell dysfunktion hos kvinnor med diabetes : en sammanställning av tillgängliga mätinstrument
Staphylococcus aureus is the most clinically important Staphylococcus species and is associated with high mortality in patients with positive blood cultures. S. aureus bacteria may cause a variety of disease manifestations ranging from minor skin infections to life-threatening conditions such as pneumonia, meningitis, osteomyelitis, endocarditis, toxic shock syndrome (TSS) and sepsis. This microorganism belonging to the gram positive cocci may also be part of the normal flora. In Sweden, penicillinase-stable penicillins are the primary alternatives to treat S.
Hur effektivt är finasteridbehandling mot ärftligt manligt håravfall?
The most common form of hair loss in young and old people is androgenic alopecia. Hereditary hair loss affects both men and women. Hereditary hair loss in some women begins at the age of 30, but as a rule hair loss begins in post-menopausal women. In women the hair thins out in an oval portion of the front part of the scalp. In men, hair loss can start as early as at the age of 20.
Utvärdering av erfarenhetsbaserade lagernivåer och arbetssätt - En fallstudie på Volvo Cars; Skövde Engine Plant
SammanfattningSyftet med denna uppsats är att undersöka huruvida det genom en övergång från erfarenhetsbaserade arbetssätt till användning av vedertagna optimeringsmetoder finns möjlighet till kostnadsbesparingar för ingående lager i O-fabriken på Volvo Cars motorfabrik i Skövde (SkEP).SkEP dimensionerar idag sina lagernivåer på erfarenhetsmässiga grunder, vilket enligt teorierna inte är helt optimalt ur ett kostnadsperspektiv. Det antas därför att det kan finnas en stor förbättringspotential om SkEP istället börjar använda optimeringsmetoder för att beräkna lager- och orderstorlekar. SkEP upplever i dagsläget inte några större problem, däremot villde veta hur pass bra deras lagernivåer egentligen är. Motiveringen till varför just O-fabriken är intressant är att cylinderhuvudena som tillverkas där är de enda komponenterna som påverkas av den aggregerade slutkundsefterfrågan och därför även kan tillämpas som typexempel vid optimering av andra komponentlager.Metoden som används i uppsatsen är i första hand kvalitativ primärdata i form av intervjuer och observationer samt till viss del sekundärdata, i form av kvantitativ information från SkEPs interna datasystem, CDEC, och en teoretisk studie i ämnet lagerstyrning.Uppsatsen börjar med en teoretisk genomgång av ämnet, vilken till största del bygger på professor Stig-Arne Mattssons publikationer. Där tas de beräkningsmetoder som används i arbetet upp, så som Kapitalbindning, EOQ, SERV2 och beräkning av säkerhetslager.
Cursum stroller : Förflyttning av litet barn för rullstolsburen
In Sweden there are 560 000 disabled people over the age of 16, half of those are in use of some kind of mobility device.Living with a disability means that due to injury or illness you are having trouble functioning without devices or assistance in your daily life and has a big impact on the independence of the disabled user.The everyday life for disabled parents with young children are different depending on the type of disability and mobility device.Today there is no alternative to the stroller for the disabled user who use mobility advises. This causes problems when the disabled person on there own have/want to move the child.The following statement have been the cornerstone for this project: How to make it possible for a wheelchair user to move a child, in the 0-2 year, for longer distances with a focus on independence and safety for both adult children?Due the process, of industrial design, this question and problem have been solved during 10 weeks. The process have contained parts as meeting with users, analyzing, concept development, evaluations, mock-up making, testing, shape & color development etc. This in the end have resulted in a full scale model of the appearance of a proposed product.The result is a stroller witch can be connected to the users specific wheelchair due two one time adjustments.
Klassifikation på webben
The thesis concerns the use of classification schemes for organising resources in subject-based hierarchical search-services on the web. The aim is to investigate the different kinds of classification that are used, which fall into two groups: established respectively new classification schemes. This is attained by studying literature and the websites of each search-service. The prospects for using classification in a web-environment are discussed and divided into three major groups: browsing, control and cross-classification. One question at issue concerns how an established scheme manages to organise web-resources and whether this classification differs from the classification of new schemes and in what way.
A comparison of group housing and individual housing for dairy bulls kept for breeding
This study was conducted at VikingGenetics' bull breeding station in Falkenberg, Sweden. The bulls waiting for the results of their progeny testing at this station are either kept in group housing or individual housing. Since both of these housing systems have advantages and disadvantages, it was in the interest of VikingGenetics to know which of these housing systems is the best. The aim of this study was to investigate the welfare of the bulls in these two housing systems through behavioural observations and the use of activity monitors. In the preparations for the study 16 bulls, 8 in each housing system, were chosen.
Överpronation kopplad till ryttarens sits
According to ?Fotförbundet" (2012), Overpronation occurs frequently (80 %) in the Western World and furthermore overpronation of calcaneus influences the position of the pelvic and thorax (Fotförbundet, 2012; Behnke, 2008).
The aim of this study is to investigate whether or not it is possible to connect overpronation of calcaneus to the problem in the rider?s seat as observed by the instructors of Strömsholm. The study will also investigate if the riders seat problems as noticed by the riding instructors are comparable with the problems found by the analyst during testing. One purpose with the study is to raise the instructors and riders awareness that anatomical deviations in the rider might influence the rider?s position in the saddle.
The questions of the study are:
- Is it possible to see seat problems in riders with overpronation of calcaneus?
- If it is possible to see more seat problems in riders with overpronation of calcaneus, do the instructors in the study considers the seat problems be similar with each other?
- If there are seat problems in the study, is it the same according to the instructors and the analyst in human biomechanics?
The hypothesis of the study is that overpronation of calcaneus has an effect of the rider?s position in the saddle.
The study is conducted as a blind study where the test subjects have been filmed (from knees down) as they walked barefooted and later while riding.
Implementering av Patientsimulator för Anestesimaskiner
In order to facilitate testing of anesthesia machines a patient simulator has been required by Maquet Critical Care AB. A patient simulator has been developed to reduce expensive and time consuming animal experiments and temporary lab arrangements. The patient simulator has been developed and designed to simulate human lungs with regards to anesthetic uptake, production of carbon dioxide and heating and moisturizing exhaled air.The system comprises a container and a test lung to simulate the volume and the dynamic of the human lung. The simulation of uptake of anesthetics has been implemented by pumping a fraction of the gas from the container through a bypass circuit with an active charcoal filter that adsorbs volatile anesthetics. The flow through the bypass circuit is generated by a pump and is controlled by a linear valve.The resulting performance of the patient simulator has fulfilled the requirements.

RailsTNE : En multimodal informationsplattform i ett interorganisatoriskt nätverk
Att utreda möjligheterna att etablera dataförsörjning riktade mot multimodala transporttjänster är idag av största intresse. Det är också intressant att försöka utnyttja de standarder som tagits fram när en dataförsörjningskedja ska etableras. Detta examensarbete genomfördes på Triona AB i Borlänge. Triona har utvecklat databasen Transport Network Engine (TNE), som idag används för att läsa in data från Nationella VägDataBasen (NVDB) och från skogsnäringen. Målet med arbetet var att ta fram en informationsmodell, som beskriver hur ett transportnät med nätanknutna data, som stödjer multimodala transporter och resor, kan lagras i TNE.
Potentiella virala zoonoser hos apor på svenska djurparker år 2008
This paper is a compilation of some of the important viral zoonosis that can be passed from apes and simians (simian and prosimian) to man. Viral zoonoses are viral diseases that can be passed from animals to humans. The paper will also provide a better insight of the risks workers and visitors to the zoo can be exposed to. The viruses that this paper is focused on is herpes Bvirus, simian T-lymphotropic virus type 1 (STLV), simian immunodeficiency virus (SIV), Ebola virus, Marburg virus, yellowfever virus, monkeypoxvirus and hepatitis B virus. The choice of viruses is based on how infectious they are and how pathogenic they are.
