Interspecies embryo transfer in South American camelids : a field study
The aim of this study was to investigate the possibility of performing inter-species Embryo transfer under actual field conditions in the natural habitat of South American camelids. In this study embryos from llamas were transferred to alpaca recipients. In a parallel study alpaca embryos were transferred to llama recipients. All animals used were free of uterine and ovarian abnormalities detectable by rectal palpation and /or ultrasound examination. Embryos were harvested twice after single ovulation in 10 mated female llamas and non-surgically transferred to synchronized alpaca recipients.
Inter-species embryo transfer in South American camelids
Embryotransfer är en metod där ett embryo i tidigt stadium flyttas från en donator till ett mottagardjur som sedan bär dräktigheten till förlossning. Det innebär att donatorhonan kan donera flera embryon under en säsong då den vanligtvis endast skulle kunna producera en avkomma. Embryo transfer är således en metod för att snabba på det genetiska urvalet i en grupp djur. Bland de mycket ekonomiskt värdefulla alpackorna i Peru, där många av herdarna saknar alternativa inkomstkällor kan Embryo transfer bidra till ett mer effektivt avelsarbete och i förlängningen en bättre levnadsstandard för alpackaherdarna och deras familjer. Studien beskriver ett experiment där ett protokoll för Embryo transfer från alpacka till lama utförs under fältmässiga omständigheter på en forskningsstation i de peruanska Anderna.
Från pre-human till post-human : Embryots reproduktiva status i skärningspunkten mellan stat och medicin
The aim of the thesis is twofold: the first aim is to identify a number of reproductive logics that are used to construct Swedish regulation of embryo donation for reproductive use as either ethical or unethical in the governmental ? and medical discussions ? and to examine how these logics are interconnected with notions of gender and parenthood. The second aim is to identify a number of tensions that arise in the application of the governmental ethical logic on the embryo and embryo donation and discuss how these tensions can be solved with a feminist material approach. I argue that the terminology used to distinguish between genetic, biological, social and legal parenthood in my material is insufficient for understanding the value of the embryo outside its pre-human status. I therefore argue for an embryonic feminist bioethics that is attentive to the embryos post-human status, and for a reformulation of the parenthood terminology in line with what I call ?reproductive ties?..
Visualizing Innovation Capital: A Case study of Technology Transfer and Biomedical start-up
Purpose: The purpose is to present a greater understanding of the progression of innovation capital in a technology transfer and biotech start-up context. The findings offer technology transfer professionals, entrepreneurs and academia an overall perception and mental framework of the technology transfer practice and the embracement of a promising invention, building upon its hidden value. Methodology: The thesis was conducted using a qualitative case study, executed with the help of interviews, in order to answer the research question: How is an embryo of innovation capital continuously cultivated in a technology transfer and biomedical start-up process? Conclusions: A technology transfer entity provides the means to establish a platform where an entrepreneur can build its own human capital, structural capital, and relationship capital. The forms of capital interact and thus create value, herein considered as innovation capital.

Etiska aspekter av preimplantatorisk genetisk diagnostik och genterapi
The research in the field of biotechnology is rapidly developing all over the world. Modern biotechnology offers unique opportunities, simultaneously as it gives rise to a number of ethical issues. Preimplantation genetic diagnosis (PGD), PGD/HLA (Human Leucocyte Antigen) and germline gene therapy (GLGT) are controversial techniques. PGD gives a possibility to identify a genetic disease prior to the embryo?s implantation in the uterus.
Anställningsskydd vid verksamhetsövergång : Vilka rättigheter och skyldigheter övergår?
Transfer of undertaking or business is a complex fact. It requires many aspects to be takeninto consideration. For there to be a transfer of undertaking or business, it has to be a stableeconomic entity that after transfer has retained its identity. The provisions regarding transferof undertaking or business is found in the transfer of undertaking or business directive,6 b § LAS and 28 § MBL.An employee?s employment is automatically transferred to the transferee.
?That´s something we people have create in our mind, because we have booring?? : En studie om språklig transfer i elevers skrivande
Syftet med denna uppsats var att studera svenskans påverkan på inlärning av och skriftproduktion i engelska bland elever i svensk grundskolas senare år och gymnasium. Studien genomfördes genom studier av elevtexter på engelska, där mellanspråkliga fel beroende på negativ transfer från svenska till engelska analyserats och kategoriserats. Resultaten visar att negativ transfer främst förekommer i grammatiska mönster som preposition + att-satser, bisatsordföljd, passivkonstruktion och i satser utan korrelat samt vokabulära strukturer som partikelverb och idiomatiska uttryck..
Erfarenhetsöverföring vid svenska utlandsstyrkan : Vilka faktorer påverkar och hur?
The purpose of this paper is to identify the factors affecting the experience transfer at the rotation of the missions. This is to identify the respective influences are inhibitory factor, which contributes to a less efficient transfer, or if it contributes to a more efficient handover. The method used for the production of this paper is a qualitative case study of squad leaders who have done service in Kosovo or Afghanistan. Through interviews with focus on the transfer of experience, both on individual and organizational level, the factors that affect are being identified. The model used is expressed in a general perspective, where each factor is categorized as inhibitory or contributing to success, and if it appears on an organizational or individual level.
Vem är rädd för bannern där? : En studie om banners klickfrekvens
This paper is about advertising on the Internet using banners. Together with Embryo Webbyrå we have tested a lot of different ways of advertising on the online newspaper of Göteborgs-Posten, gp.se. Two of the web bureau?s existing clients, Resia and Recip, were chosen for the ads and the whole campaign lasted a period of four weeks.By comparing our banners with the consideration of format, color, placement and content we wanted to find an answer to how the most optimal banner would look.Our test result shows that visitors rather do not want to click on a banner, although we think that we have seen some interest and curiousness from visitors in the banners content. Even when the visitor does not click on a banner, the message might be put in mind for a future purchase or act..
Mer än ett pris - : En studie om information, uppfattningar och användning av internpriser.
Background: When companies decentralize their operations into profit centers, transfer pricing often becomes an integral part in intracompany trade. A profit center may affect both revenues and costs and seek to maximize profit. Transfer Pricing is a complex subject because it is affected by a large number of factors including the profit centers will to generate profits. This leads us to the subject of decision-making in a transfer pricing-systems. On what grounds are decisions made? Are transfer pricing purposes, factors and interests taken into consideration? What type of information is used in such decisions, how is the transfer price issue perceived and how is it used?Aim: The purpose of this thesis is to analyze which type of information that is makes up transfer prices, how the transfer price is perceived by different parties and how it is used for decision-making.Completion: A qualitative study has been performed with current theory as a starting point.
Immunohistochemical study of hemoglobin-related proteins in endometrium from fertile and infertile women
In couples diagnosed with unexplained infertility, the woman has normal ovulatory cycles and no organic pathology, and the man has normal semen. The period during which the implantation of an embryo can occur is defined as the window of implantation (WOI). For infertile women, disturbances in the endometrium maturation are hypothesized to impair the uterine receptivity for embryo implantaition. However, there are still no methods found to predict endometrial receptivity.Hemoglobin related-proteins hypothesized to be involved in embryo implantation have been found in the endometrium in both fertile and infertile women. The aim of this study was to determine whether there were differences in the expression of hemoglobin-related proteins, hemoglobin-?, cytoglobin, fetal hemoglobin and haptoglobin in the endometrium of fertile and infertile women.
SAS EuroBonus ? Tillgång eller skuld?: En fallstudie av hur värdet av ett lojalitetsprogram påverkar internprissättningen
This paper presents a study of Scandinavian Airlines? (SAS) frequent flyer program, EuroBonus. The study describes the transfer pricing of award seats between EuroBonus and the airlines within SAS. Furthermore, it aims to determine what effects market-based transfer pricing would have on EuroBonus, the airlines within SAS and consequently on the SAS Group. We have found that the existing transfer pricing does not provide incentives for the airlines within SAS to satisfy EuroBonus? demand for award seats.
Internprissättningsproblematiken i ljuset av förslaget om hemlandsbeskattning för europeiska koncerner
Throughout this thesis three main factors have been identified that can be out of significance for transfer pricing in multinational companies if the proposal for Home State Taxation is adopted. These factors are rules for calculation of the tax base, rules for dividing costs over periods and the tax rate. The formula for sharing profits will also become a factor that can have an impact on the European companies'incentives for transfer pricing interacting with above-mentioned factors. The effects of transfer pricing aiming at reducing the total amount of the taxation burden for a group of companies will be strongly reduced in the future if the proposal is adopted. Incentives for transfer pricing will loose importance, though not disappear altogether.
Honan och ägget
Honlig reproduktion är ett brett och komplicerat ämne. I detta arbete analyseras läror och teorier om honan och hennes reproduktion i ett försök att se närmare på de detaljer som påverkar olika aspekter på att vara hona. Arbetet delas upp i olika avsnitt som fokuserar på de
olika faktorerna genetik, fysiologi och beteende. Även embryonal utveckling kommer att belysas, då tillväxten och omhändertagandet av avkomman påvisar tyngden av samverkan
mellan de ovan nämnda faktorerna. Trots att väldigt få konkreta svar existerar i nuläget är de många teorierna en utmärkt utgångspunkt för att förstå vikten av beteenden, strategier, fysiologi och genetik inom olika arter för deras framgång under utvecklingen..
