Validation of KIDScore? D3 Basic, a morphokinetic model for improved embryo selection

ABSTRACT Infertility is a medical condition that affects approximately 16 % of Swedish couples in childbearing age and is a condition found in both men and women. When a couple has been trying to conceive for more than 12 months without success they need to see a health care provider. Infertility can be treated with medicine, insemination or assisted reproductive technology such as in-vitro fertilization (IVF) and intra-cytoplasmic sperm injection (ICSI). The aim of this study was to validate a morphokinetic selection model, KIDScore? D3 Basic, against morphological selection model that is currently in use at the Fertility unit at University hospital in Orebro.

Elimineringen av korridormetoden - Hur svenska företags nyckeltal påverkas

In 2011 the International Accounting Standards Board issued amendments to IAS 19 Employee Benefits. The new standard is effective from January 1st 2013 and one of the largest changes in the standard is the elimination of the corridor method. Through the corridor method companies had the possibility to defer actuarial gains and losses resulting from their defined benefit obligations (pension obligations) and leave them unrecognized off the balance sheet. According to the new standard companies reporting under International Financial Reporting Standards will have to recognize all actuarial gains and losses immediately in other comprehensive income. The aim of this thesis is to examine how the financial key ratios of Swedish listed companies will be affected by the elimination of the corridor method.

Experimentell studie av kinetiken vid peroxidblekning av pappersmassa

Vid TCF-blekning av pappersmassa är väteperoxid en av huvudkemikalierna. I dagsläget är det svårt att styra blekstegen. Operatörerna måste ta hänsyn till produktionstakt, blekbarheten på massan varierar och fördröjning i trender. PO-bleksteget på Södra Cell Värö har en ungefärlig uppehållstid på 4 timmar och det är först efter så lång tid som man kan se hur en förändring verkligen slår igenom. Överblekning kostar väldigt mycket i kemikalieåtgång och det är därför efterfrågat ett sätt att kunna styra och optimera peroxidblekningssteget.

Första mötet med förskolan : en kvalitativ studie om olika inskolningformer på fyra förskolor

This is a qualitative study with four interviews, in four different preschools, in the same municipality. By making it so, it becomes a case study to describe a phenomenon in a municipality which also is the definition for this investigation. The purpose of my study is to examine what it means, in a municipality, to have different types of introduction at preschool. Where I ask the question why preschools choose to have a specific method of introduction and what are the basics and ideas behind the choice of the method? What significance do these different methods have to attachment theory? What do teachers think about the advantages and disadvantages with their choice of method?The versions of introductions are many and may vary; the duration of the introduction may vary from 1-3 days up to 3 weeks.

Optimering av slutfasstyrning

Modern missiles must meet higher and higher demands. They should be autonomous, have long range and still have a big effect on the target. To maximize effect on target some missiles not only minimize miss distance, but also try to hit with a certain angle; often perpendicular to the surface of the target. In this thesis a method to guide the missile in the terminal phase of its mission where both point of impact as angle of impact are specified. The method consist of two parts.

Läcksökning med penetrant ? kvalitetssäkring av

Vacuum box leak testing is, because of geometrical problems, not always possible andtherefore an alternate test method with dye penetrant is used. DEKRA Industrial has identifieda need for quality assurance of the method and development of a written procedure withguidelines that lead to more uniform ways of testing.A literature study was done to get a general overview of nondestructive testing (NDT) and tosee how the method is used in different applications. European and American standards werestudied. Analytical and numerical solutions, involving flow simulation, were deemed to berather difficult and beyond the scoop of this project. Thus the problems had to be solved byusing experimental methods.

Keratitbehandling, antibiotika versus corneal collagen crosslinking (CXL) genom riboflavin och UVA

Syfte: Syftet med denna studie var att jämföra antibiotikabehandling med corneal collagen crosslinking (CXL)-behandling genom fotoaktivering av riboflavin vid bakteriell keratit. Att experimentellt undersöka om en viss stam av Pseudomonas aeruginosa kunde infektera cornealt epitel var också en del av studien.Metod: Litteraturstudie samt ett experiment med Pseudomonas aeruginosa och grisögon in vitro.Resultat: Dagens behandling av keratit är initial med antibiotika. I experimentella studier har CXL använts både i kombination med antibiotika och som enskild behandling. Positiva resultat från studier med CXL som behandling mot keratit har rapporterats.Resultatet av det experimentella försöket pekar på att den stam av Pseudomonas aeruginosa som användes i experimentet inte kan penetrera ett intakt epitel.Slutsats: CXL kan bli en viktig och användbar behandlingsform vid keratit, särskilt med tanke på den ökade antibiotikaresistensutvecklingen. Ytterligare forskning på området krävs dock innan metoden kan bli fullt vedertagen.För att kunna fastställa om stammen av Pseudomonas aeruginosa i det aktuella experimentet har virulensfaktorer för att ta sig in i ett oskadat epitel eller inte krävs fler försök..

Är verkligheten indelad i ämnen? - en undersökning av elevers upplevelser av ämnesövergripande arbetssätt i tematisk form

Our purpose with this essay was to explore students? experiences of interdisciplinary working method in thematic form. With a starting point from Lpf-94, the curriculum for the upper secondary school and several theories of learning, we wanted to explore if interdisciplinary working method in practice could create an environment for a meaningful learning situation. The study took place in an upper secondary school class, study preparatory, third grade, who works interdisciplinary in thematic form. Our study was qualitative and we used an open structural questionnaire where the students confidentially were able to describe the working method, explain which subjects that participate in the work, and bring forward good respectively bad factors about the method.

Strukturegenskaper hos cerealier och dess betydelse för stärkelsens nedbrytningshastighet : metodutveckling av stärkelsehydrolys in vitro och bestämning av hydrolysindex (HI)

Snabba kolhydraterna har i kostdebatten ibland utpekats som en av orsakerna till metabola syndromet (insulinresistens och höga blodfetter). Stärkelsen i sin renaste form bidrar till att blodsockernivån höjs dramatiskt efter måltid precis som en ren glukoslösning. Att vi skall undvika att äta ren glukos för att minska risken för metabola syndromet känns naturligt, men att undvika stärkelserika livsmedel är svårare att förstå. Det kräver ett nytt tänkande att dela in livsmedel i snabba och långsamma, beroende på hur de påverkar blodsockerhöjningen efter en måltid. Många livsmedel har fått ett glykemiskt index (GI) som ett mått på kolhydraternas kvalité.

Utvärdering av Transportstyrelsens flygtrafiksmodeller

The Swedish Transport Agency has for a long time collected data on a monthly basis for different variables that are used to make predictions, short projections as well as longer projections. They have used SAS for producing statistical models in air transport. The model with the largest value of coefficient of determination is the method that has been used for a long time. The Swedish Transport Agency felt it was time for an evaluation of their models and methods of how projections is estimated, they would also explore the possibilities to use different, completely new models for forecasting air travel. This Bachelor thesis examines how the Holt-Winters method does compare with SARIMA, error terms such as RMSE, MAPE, R2, AIC and BIC  will be compared between the methods. The results which have been produced showing that there may be a risk that the Holt-Winters models adepts a bit too well in a few variables in which Holt-Winters method has been adapted.
