Resumen

As medical technology has advanced, so too have our attitudes towards the level of control we can expect to hold over our procreative capacities. This creates a multi-dimensional problem for the law in terms of access to services which prevent conception, access to services which terminate a pregnancy and recompensing those whose choices to avoid procreating are frustrated. These developments go to the heart of our perception of autonomy. In order to evaluate these three issues in relation to reproductive autonomy, I set out to investigate how the Gewirthian theory of ethical rationalism can b

Resumen

Surrogacy is an arrangement whereby a woman conceives in order to give birth to child or children for another individual or couple to raise. This thesis explores how commercial gestational surrogacy is culturally framed and socially organised in Russia and investigates the roles of the key actors. In particular it explores the experiences of surrogacy workers, including those who migrate or commute long distances within and to Russia for surrogacy work and the significance of their origin, citizenship, ethnicity and religion in shaping their experience.

Resumen

The success of implantation depends on the synchronous development of the embryo and the endometrium. This process is recognised to be regulated by the endocannabinoid system, the most widely studied of which is anandamide.;The first part of this study was the development of a robust assay to measure anandamide in human plasma. The assay was then applied to measure anandamide concentrations during the menstrual cycle, pregnancy, labour and in a group of women presenting with threatened miscarriage. The mean plasma anandamide levels in the follicular phase were 1.68 nM compared to 0.87 in the l

Resumen

This thesis is concerned with the problem of reproducing a desired sound field with an array of loudspeakers. A theory based on functional analysis and the theory of integral equations is developed for the study of this problem. An attempt is made to develop a mathematical framework that can be adopted as a generalized theory of sound field reproduction. The reproduction problem is formulated as an acoustical inverse problem, in which the target sound field is given on the boundary of a control volume located in the interior of the loudspeaker array, while the loudspeaker signals required for

Resumen

Commercial gestational surrogacy, also called contract pregnancy, involves privately contracting a biogenetically curated pregnancy using IVF. It distinguishes itself from what is commonly considered 'natural' in procreation, in that the human fetuses it produces are formally entered into a legal unit other than the family of the gestator. My work here contends that this practice is best thought, not in isolation, but in the context of social reproduction more generally and as a central component of future geographies of fetal manufacture that would treat (all) pregnancy as work.

The methodology to study skin colour preference was then applied to study the colour preference of two other important colour categories: green foliage and blue sky. There are three essential parts for preferred skin colour enhancement: 1) building a skin colour model to detect skin colours or skin pixels; 2) finding a preferred skin colour re

Resumen

Ants and other social Hymenoptera (social bees and wasps) have a remarkable mating strategy. Social Hymenoptera live in societies where reproduction is monopolized by a fertile caste consisting of males and queens. On the other hand, the logistical tasks of the colony are carried out by a sterile female caste known as workers. Reproductive individuals mate during a single bout early in their life and will never engage in additional reproductive events later on. Males die soon after mating while queens store millions of sperm cells in a specialized organ, the spermatheca. Queens will use this s

<p>The color gamut, i.e. the range of reproducible colors, is in most conventional display systems not sufficient for accurate color reproduction of highly saturated colors. Any conventional three-primary display suffers from a color gamut limited within the triangle spanned by the primary colors. Even by using purer primaries, enlarging the triangle, there will still be a problem to cover all the perceivable colors. By using a system with more than three primary colors, in printing denoted Hi-Fi color, the gamut will be expanded into a polygon, yielding a larger gamut and better color reprodu

Albeit widely researched, significant controversies that surround the disease remain unsolved, from the clinical presentations, diagnosis, right through to its management strategies. Despite the rapid advancement of technology in modern medicine, the ideal diagnostic and investigative tool of the disease remains elusive, and hence the management of the disease remains a challenge to clinicians.

Although genomes are perhaps the single most important element of living systems, why they feature such striking variation and how this variation is maintained within and across natural populations remains unclear. One of the most common and important means by which genomic variation is generated is ploidy elevation.

The current method to identify oestrus consists of examining urine samplesfor presence of cornified cells. To collect urine, the animals have to be removed from their cages and restrained.

Male butterflies have some certain pathways to prevent the female butterfly which has mated with them from mating with other butterflies.
