CORRELATION BETWEEN ENDOMETRIAL MARKERS AND PREGNANCYOUTCOME IN WOMEN WITH UNEXPLAINED INFERTILITY

ABSTRACTA defect implantation process is the major reason for unexplained infertility. Estrogen andprogesterone are steroid hormones preparing the endometrium for implantation. They mediatetheir effect through their receptors: estrogen receptor alpha and beta and progesteronereceptor A and B, respectively. Leukemia inhibitory factor (LIF), which is also important forimplantation, mediates its effect through LIF receptor and the coreceptor, gp130, and is downregulated by suppressors of cytokine signaling 1. The aim of the study was to compare thelevels of the steroid hormone receptors and LIF related factors in the endometrium of twogroups of women with the diagnosis unexplained infertility: one that became pregnant afterassisted reproduction and one that did not become pregnant.

Evaluation of specificity of a walnut antiserum and detection of English walnut (Juglans regia) in food with ELISA and Real-Time PCR

Nuts of all kinds are common ingredients in food. For nut allergy sufferers the frequent use of nuts cause problems and "hidden" nuts in food products may elicit allergic reaction when such foods are consumed. Methods for detecting and quantifying walnut (and other nuts) with high sensitivity and specificity are therefore very important.The objective of this project was to verify the specificity of a rabbit antiserum against walnut with immunodiffusion and to determine the size of the dominant walnut antigens with Western blotting. In addition, a commercial sandwich ELISA for walnut quantification was validated and compared with a qualitative real-time PCR.The rabbit antiserum proved to be less specific but after absorption with cross-reacting nuts and seeds it showed high specificity. The ELISA kit reacted, except for walnut, with pecan and slightly with other nuts and seeds tested.

Utvärdering av en beslutsåterkopplad kanalestimator för tredje generationens mobiltelefonisystem

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER). An improvement is only seen when the BER becomes much lower than what is common in real situations. In conclusion DDCE is complicated, involves many mathematical operations and gives insignificant improvement of SNR when BER takes common values. It is legitimate to question if it is possible to use the method in a real mobile phone system..

"En riktig våldtäkt" : - en kunskapsöversikt om föreställningar om våldtäkt

This essay is a selective review of Nordic literature with the aim to explore contemporary conceptions of male-on-female rape, to increase the understanding of how these can construct ?a real rape?. To achieve this two questions were formulated: What circumstances can cause an incident not to be defined as rape? What circumstances can cause an incident to be defined as rape? Searches in international and Swedish databases led to initial selection of peer-review journal articles and dissertations that were reviewed against set criteria. These criteria were met by 8 studies, that were assigned codes, from which comprehensive categories were developed.

Livförsäkringar och efterarv

In recent decades, demands has emerged that the companies shall take a greater social responsibility for the impact that they have on their environment and that this impact shall be reported, which is known as Sustainability Reporting. The Sustainability Report is based on a number of general principles that ensure the content and the quality of the Sustainability Report. One of these principles is the principle of completeness. In the research, this principle seems to have been interpreted in terms of number of reported aspects and indicators, which can be a limited view where only the existence of the aspects and indicators is observed. By including the degree of the reporting in terms of full, partial and no reporting as well as a comparison between the real and the alleged reporting, our intention is to extend the principle of completeness and to develop a tool that we also apply through an empirical survey in a particular area.

TaqMan® Sample-to-SNP Kit? : evaluation of kit for low-cost and fast preparing of DNA-samples before genotype analysis

 Genotyping can be used to link genetic variation among individuals to certain diseases or conditions. Some known disorders and states that are dependent on single nucleotide polymorphism (SNPs) are lactose intolerance, venous thrombosis, hereditary hemochromatosis and the difference in sensibility among people to metabolise drugs.In this project a new kit, TaqManÒ Sample-to-SNP KitÔ for extraction of DNA and preparation of the extract for genotyping with real-time PCR and allelic discrimination, was evaluated. QIAamp® DNA Blood Biorobot® MDx Kit was used as the reference method.The purpose of the comparison was to find a method that makes DNA extraction from blood samples cheaper and faster, but with the same reliability as the reference procedure.The results of the evaluation showed a complete agreement of the genotype results between the methods tested, which means that the new method was as reliable as the reference method. The costs of reagents and material would be reduced with 52% if the new method is adopted, that alone would result in a cost reduction of 144 000SEK a year with a sample volume of 650 samples/month. The time for DNA extraction would also be reduced with the new procedure. .

The Tenant Way. Fastighetsbolags strategiska arbetssätt avseende kommersiella hyresgäster

Fastighetsbranschen står inför en förändring. Forskning tyder på att fastighetsbolag kommer att gå mer och mer mot att bli mer traditionella tjänsteföretag och att pengar inom branschen kommer att tjänas genom att vara en så duktig förvaltare som möjligt i avseende till fastighetsdrift och hyresgästförvaltning. Denna kandidatuppsats fokuserar därför på att undersöka hur fastighetsbolag kan utveckla sina tjänster mot sina hyresgäster samt vilka faktorer som kommer vara avgörande i framtiden för att bli ett framgångsrikt fastighetsbolag.SyfteProjektets syfte är att göra en undersökning över hur fastighetsbranschen troligtvist kommer att förändra sitt strategiska arbete mot sina hyresgäster och vilka faktorer som då kommer att karaktärisera ett framgångsrikt fastighetsbolag.Frågeställningar?

Svenska myndigheters användning av sociala medier : Vilka mål har myndigheterna med sitt användande av sociala medier samt hur mäter myndigheterna effekten av sitt arbete?

Swedish authorities have been dealt a mission by the Swedish state, where each agency works on the basis of their assignment. Communication has become more and more important for authorities, there are several reasons for the use of communication and they may differ from authority to authority. Some authorities claim that the purpose of the communication work is to create awareness and recognition among citizens. A communication form that has become increasingly important for government agencies is social media, according to the government authorities should implement social media in their communication work because it is very important that the authorities are available where the citizens are. Previous research has focused on the risks and opportunities that the social media generates for the public sector.


Design och konstruktion av mätuppställning för induktiv mätning av magnetisk spinndynamik

Development in spin dynamic occurs in the whole world because of therising demands on fast electronic storage for example hard drivesand RAM (Random Access Memory). Measuring the spin resonance of amaterial gives you the insight of the theoretical speed for amagnetic memory. This means the maximum storage speed is below thefirst resonance. All magnetic materials have different propertiesthat will inflict the resonance frequency which brings that theconstructors of memories need to know which magnetic material theywill use to obtain best results. In the market for normal users themaximum storage speed in a RAM memory is 1.6 GHz.

Referensgrupper för ungdomar på folkbibliotek en bra idé?

The aim of this master thesis is to find out if young people and librarians think that reference groups can support public libraries to meet the needs of young people, and if the reference groups, which the librarians describe, differentiates from the young peoples requirements. I have made a qualitative study with a questionnaire to six librarians who have experience from reference groups and ten interviews with teenagers. The result showed that young people have many interests and needs which can be met from the library. The teenagers were positive to the library and many of them showed interest in having more influence on the library. Many would like to join a reference group, but on the condition that they would be offered real influence.

The aim and goal of this work has been to design and implement a voltage reference network for a 12-bit PSAADC, Parallell Successive Analog to Digital Converter. A chip containing the design has been sent away for fabrication. Because of the long processing time, no measurement data are presented. The main specifications for the voltage reference generator is to generate stable reference voltages with low noise and a good PSRR. Efforts has also been made to minimize the power consumption..

RTLS - real time location systems : an inventory study for agriculture applications and requirements

The trend towards increasingly large farming units raises questions regarding how to better monitor production. Larger units make the impact from possible errors more severe, which increases the pressure on management supervision. To cope with management issues, prevent errors and handle increased demands on traceability and documentation, the Real Time Location Systems (RTLS) concept is making its way into various parts of agriculture. In sectors outside agriculture, RTLS are already being used successfully to track and locate items through nodes at different levels of accuracy, such as room level or the relative or absolute position. Empirical data can be received in real time from the nodes.
