Domain-independent programming by demonstration in existing applications
No full textThis paper describes Familiar, a domain- independent programming by demonstration system for automating iterative tasks in existing, unmodified applications on a popular commercial platform. Familiar is domain- independent in an immediate and practical sense: it requires no domain knowledge from the developer and works immediately with new applications as soon as they are installed. Based on the AppleScript language, the system demonstrates that commercial operating systems are mature enough to support practical, domain- independent programming by demonstration – but only just, for the work exposes many deficiencies
Identification of viable embryos in IVF by non-invasive measurement of amino acid turnover
No full textBACKGROUND: IVF is limited by low success rates and an unacceptably high multiple pregnancy rate. These outcomes would be improved significantly if a single embryo of high viability could be replaced in each treatment cycle, but widespread acceptance of such a policy is hindered by the lack of predictive factors for embryo selection. We have conducted a retrospective clinical study of a novel non-invasive method of embryo selection based on the depletion/appearance of amino acids in the culture medium. METHODS: Fifty-three cycles of IVF treatment using ICSI were studied. Embryos were cultured for 24 h in 4 µl drops of medium containing a physiological mixture of 18 amino acids. The spent medium was analysed for amino acid content by high performance liquid chromatography. RESULTS: The turnover of three amino acids, Asn, Gly and Leu, was significantly correlated with a clinical pregnancy and live birth. These correlations were independent of known predictors, such as female age, basal levels of FSH, embryo cell number and embryo morphological grade. CONCLUSIONS: Non-invasive assay of amino acid turnover has the potential to improve significantly the prospective selection of the most viable embryos, or single embryo, for replacement in an IVF cycle
Review on the B.A. Muratov’s monograph “Ethnogenesis of the Bashkirs: Historiography and Contemporary Research”
No full textThe author of this review examines four main types of errors contained in the B.A. Muratov’s book “Ethnogenesis of the Bashkirs: Historiography and Contemporary Research”.
Factual errors. The author often makes factual errors by inventing some facts or ideas, which he attributes to certain researchers.
Methodological errors. An improper use of the population genetics methods has led the author of this monograph to incorrect conclusions. The author does not use at all such methods as multidimensional scaling, calculation of genetic distances, AMOVA, cluster analysis, etc. In turn, the author incorrectly uses such methods as the construction of phylogenetic networks and the allocation of close haplotypes based on networks of clusters. The author has not made a selection of modal haplotype (haplotype of the founder). He made a lot of mistakes in calculating TMRCA (the lifetime of the first common ancestor) based on genealogical and evolutionary rates of mutations. One of the main error is the small sample size for the study of Bashkir clans (n=45). Therefore, the conclusions drawn from such a small sample, are poorly reasoned.
Historical fantasy. For example, B.A. Muratov quite unreasonably hypothesizes about the genetic connection of the Bashkir tribe Burzyan with the Mongol tribe Kiyat-Bordjigin. He also put forward unsubstantiated hypotheses about the genetic connection of the same Bashkir tribe Burzyan with Kurds, Ossetians-Digorians, Berendeys. At the same time. Muratov, naturally, did not provide any genetic evidence (belonging to a common terminal SNP-marker).
Grammatical mistakes. The main thesis of the B.A. Muratov’s book sounds like: the Bashkirs are (certain) “Turanians”. The main mistake here is the identification of SNP-marker Z2123 with the ethno-religious category of “Turan”. This identification is not methodologically correct as social constructs and genetic markers are different in nature of their appearance, functioning and development. Thus, the mixing of genetic markers and ethno-religious is not methodologically correct when reconstructing history
Numerical and experimental research of wave interaction with a porous breakwater
No full textThe design formula for rubble mound breakwaters by Van der Meer has an unclear Notional Permeability term. This term causes a lot of confusion for designers. In the past many people have tried to derive a better formulation for that term by experimental and analytical research. The goal of this study was to obtain a better formulation along a numerical way. This study explores the numerical possibilities and tries to define which direction has to be taken in future research. As a first step, a very simplified case is taken with a vertical homogeneous breakwater which interact with monochromatic waves. In total six different blocks were made of epoxy and elastocoast. Only 4 out of the 6 blocks were tested. Also the porosity (n), laminar friction (?) and turbulent friction constant (?) of the blocks were determined experimentally. This way the experimental results could be compared with computations. These experiments have been done in the large flume of the Environmental Fluid Mechanics Laboratory of the TU Delft. Two types of data were collected: pore pressures and water levels in front and behind the block. The water levels seemed to be the most reliable data. The main deficit of the setup was the wave absorber at the end of the flume. The wave absorber is not able to sufficiently absorb long waves. So the dataset had to be corrected for that effect. The created dataset was in line with results from earlier experiments. Results were compared with an analytical solution and the numerical SWASH model. Comparisons with the analytical solution showed a reasonable fit without any calibration. The SWASH model showed in first instance large deviations using the same dataset. By calibrating the turbulent flow resistance ?, it was possible to generate a decent fit. However, the used ? constants are 6-10 times higher than the measured ? constants. This is physically unrealistic high. Therefore the most likely explanation is an error in the transition between the water and the porous medium. During the experiment discontinuities can occur on this transition while SWASH uses an continuity requirement. Numerical tests were performed on some multi-layered combinations of the different blocks in order to derive a "Vertical P" value in a similar way as Van der Meer determined his P=0.4 structure. The results showed, nevertheless, quite some different patterns as the computations done by Van der Meer. However, taking into account all the problems with calibrating the SWASH model the results for the notional permeability seemed very promising. This numerical method shows the possibility of numerically calculating a notional permeability and should be investigated further in the future.Enviromental Fluid MechanicsHydraulic EngineeringCivil Engineering and Geoscience
Norma Coverdale, B.A.: the treatment of women in selected works of Henry de Montherlant
No full textThe aim of this thesis is to determine how women are treated in selectedworks of Henry de Montherlant. This is explored by examining their relationshipswith other women as well as with men. Inevitably, this leads to an analysis ofthe multifaceted area of love. Part I researches Montherlant's prose work and included in this section is the investigation of the importance of 'l'ordre male' to the author and the influence this exerts over his early prose work in the areas of tauromachy, war and sport, and where the male adherence to this concept leaves women. The 'syncretisme et alternance' which is central to Montherlant's thinking is explored in this section.Part 2 is concerned with Montherlant's theatre in which the psychological development of the main characters is of great importance. It is in this section that a comparative study is made of the influence of Mme. Elisabeth Zehrfuss' written contribution to La Reine morte. Her unpublished notes are set out in full in the Appendix. The thesis also draws on the unpublished correspondence between Henry de Montherlant and Elisabeth Zehrfuss between the years 1934 and 1945. An investigation is made as to whether or not there are any differences between the way women are treated in Montherlant's prose and in his theatre and the conclusion is drawn that there are
Cone biopsy in pregnancy
No full textA retrosp~ctive analysis of all cone biopsies performed on pregnant patients at Groote Schuur Hospital from 1965 to 1969 is presented. The study showed that a significantly high maternal complication rate and foetal wastage was associated with the procedure. It is recommended that the procedure be abandoned in pregnancy and the abnormal cervical cytology be investigated at the end of the puerperium
Embodying identity through tattooing: Autoethnography and the “bodyscape”
No full textFans of Heavy Metal music have a unique style of appearance and interaction through which a sub-cultural community is formed and maintained. This presentation describes aspects of Dave’s autoethnographic doctoral thesis in relation to the embodied nature of tattooing and the display of cultural symbols associated with the shared identity of Metaller. Drawing upon Dave’s interactions with one of his heavily tattooed participants, referred to affectionately in this research as “Chopper”, he will discuss the ways in which tattoos and associated descriptions can render into view community assumptions, practices, and relationships.
Chopper’s tattoos are colourful and embodied statements of membership and community. By focusing on the dialectics of tattoos and their metonymic relationship with a Heavy Metal
community, we explore how this participant’s sense of self as a member has been imprinted upon his flesh. The concepts of metonym and bodyscape are employed as a means of exploring and theorising the construction, expression, and performance of identity and community at sub-cultural events such as local gigs. Such events provide opportunities for bodyscapes to be enacted through social interactions. Our analysis moves beyond the description of specific representations to broader observations about the ways in which social relationships and community are rendered meaningful through mediated and interpersonal communication featuring these tattoos
