Descriptive characterization of a Nigerian heterogeneous rabbit population - factors affecting litter traits
No full text[EN] This study evaluated the effect of female body weight at conception (FWC), season of mating (SM), type of mating (TM) and litter size at birth (LSB) on the litter performance in a heterogeneous Nigerian population of rabbits. Data on 116 litters from 10 bucks and 48 does across three parities were analysed. Reproductive traits evaluated included LSB, number born alive (NBA), litter sizes and weights at 7, 14 and 21 d post-kindling, pre-weaning survival rate (SR) and daily weight gain of kits from kindling to weaning (DWG). A fi xed linear model that included FWC (light and heavy does), TM (homospermic and heterospermic matings), LSB classes (low, medium and large) and SM (rainy or dry) was used. Results showed that heavier does at concenption showed higher performance for LSB and NBA (P<0.05) than lighter does. Average weight of kits at kindling and at 28 d, as well as kit SR and DWG, were signifi cantly higher in low-sized litters, when compared with intermediate- and large-sized litters (P<0.05). LSB, NBA and litter size at weaning were higher in litters produced by heterospermically mated does compared with homospermically mated does. Season of mating affected LSB and NBA (P<0.05), being signifi cantly larger the litters in the rainy season.The authors gratefully acknowledge the International Foundation for Science (IFS) of Sweden for its financial support (through grant B3871-1).

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
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
“Sweet Christ this was good” – Analysing recommendations in movie reviews
No full textThe author of this post is Julia Mizerski, a B.A. student of English Studies at the University of Bonn, who has written an excellent term paper in the course “The Pragmatics of Digital Communication” (Dr. Stefanie Pohle) in the summer term 2018. Have you ever watched a movie after reading a very convincing review? Or have you ever wondered how a reviewer manages to get you excited about a movie? Well, I did, and so I chose to explore how the comment “Sweet Christ this was good” on the movie..
Crossing the "divide": Virtual ethnography in the "real world"
No full textThis presentation documents an aspect of my autoethnographic doctoral thesis that investigated issues of identity and community. The presentation explores the inter-connected and overlapping nature of social media sites such as Bebo, Myspace, and more recently Facebook and Twitter, with peoples’ offline experiences. Such sites are representational spaces that extend the offline self into the online world. Through the use of text, images, and
video, my participants expressed their personal and social identities online, as a way to encourage interactions with like-minded people in order to further develop identity. Through the on-going development of these sites, users develop not only representational spaces, but also interactional spaces for developing and experiencing community. These websites are interwoven into peoples’ everyday experiences and routines. People update Facebook
statuses to tell others what they had for breakfast that morning, post embarrassing photographs and comment, or attempt to relive sensual experiences of sights, sounds, and
even smells of events they have attended together or separately. The online realm is also brought into the offline one, with people scrambling for a camera, accompanied by the modern day catchphrase of “don’t pose like that or it’ll end up on Facebook” What this means
is that rather than being distinct, mutually exclusive spaces, social networking sites are but one of many physical and virtual spaces that people travel across, through, and within their everyday lives. People interact with both online and offline spaces, layering them with meaning and linking them together through social interactions

An Evaluation of the Thornthwaite-Holzman Equation for Evapotranspiration
No full textTitle: An Evaluation of the Thornthwaite-Holzman Equation for Evapotranspiration, Author: Neil B.A. Trivett, Location: ThodeEvapotranspiration involves a complex set of processes
which relate to the loss of water to the atmosphere. It involves
the uptake of water by the root system of plants, its movement through
the plant, and its diffusion through the stomata into the atmosphere.
The term evapotranspiration (Et) includes evaporation from the soil
and transpiration from vegetation. Two of the basic reasons for studying evapotranspiration are as follows: 1) Since it is the reverse process of precipitation, it has major consequences in agriculture through its control on plant growth. 2) It is one of the important energy fluxes from the earth's surface and is an integral part of the energy balance.ThesisBachelor of Arts (BA
