Public Monuments and the Development of Siamese Nationalism, 1908-1945

A careful study of Siam's public monuments is the key to understanding the development of the Siamese nation in its formative period, from 1908 to 1945. As Siam's elites attempted to modernize the state in order to compete with the more developed powers of the West, they recognized that nationalism could potentially be used as a force to increase popular unity, consolidate modernization programs, legitimize their own authority, and protect the country from foreign conquest. The problem they faced, however, was how best to communicate nationalism to the people. Different factions throughout this era had their own idea of what it meant to be Siamese, and all of them wanted to control the national image. But literacy in Siam was extremely low, and art too expensive for most individuals to possess. Public political monuments, the focus of this thesis, therefore became the primary means of manifesting and propagating the underlying tenets of the new Siamese nation. Public monuments express the changing imaginings of the Siamese nation in this period of enormous transformations and turbulence, through the motives behind their commissioning, the political messages they convey, and popular reactions to the monuments. Three primary strains of Siamese nationalism emerged during this period: royalist nationalism, republican nationalism, and military nationalism. These three imaginings of the nation continually developed and interacted with each other, but each was particularly dominant at a given time in Siamese history. Monuments of the royalist period (1908-1925) embody the desire of Siam's kings to not only promote national pride amongst the Siamese people, but also advocate an image of nation and king as one. Monuments of the republican period (1925-1939) express the changing and sometimes contradictory events of their times, as they demonstrate new national values based on the sovereignty of the people, the value of the constitution, and the growing power of the military. And monuments of the military period (1939-1945) espouse an assertive and militaristic national image of warfare, patriotism, authority, and vigor. This thesis explores the nationalistic themes expressed in these monuments, and how these themes played out in the course of Siam's wider history.

Contiguous ∼16 Mb 1p36 deletion: Dominant features of classical distal 1p36 monosomy with haplo-lethality

Monosomy 1p36 results from heterozygous deletions of the terminal short chromosome 1 arm, the most common terminal deletion in humans. The microdeletion is split in two usually non-overlapping and clinically distinct classical distal and proximal 1p36 monosomy syndromes. Using comparative genome hybridization, MLPA and qPCR we identified the largest contiguous ∼16 Mb terminal 1p36 deletion reported to date. It covers both distal and proximal regions, causes a neonatally lethal variant with virtually exclusive features of distal 1p36 monosomy, highlighting the key importance of the gene-rich distal region for the "compound" 1p36 phenotype and a threshold deletion-size effect for haplo-lethality.

Best combination of pre-stimulation and latency period duration before cluster attachment for efficient oxytocin release and milk ejection in cows with low to high udder-filling levels

Experiments were designed to investigate the suitability of a combination of a short manual teat stimulation with a short latency period before teat cup attachment to induce and maintain oxytocin release and milk ejection without interruption. In Experiment 1, seven dairy cows in mid lactation were manually pre-stimulated for 15, 30 or 45 s, followed by either 30 s or 45 s of latency period. It was shown that all treatments induced a similar release of oxytocin without interruption until the end of milking. In particular, the latency period of up to 45 s did not cause a transient decrease of oxytocin concentration. In Experiment 2, milking characteristics were recorded in seven cows each in early, mid, and late lactation, respectively. Because the course of milk ejection depends mainly on the degree of udder filling, individual milkings were classified based on the actual degree of udder filling which differs between lactational stages but also between morning and evening milkings. All animals underwent twelve different udder preparation treatments, i.e. 15, 30, or 45 s of pre-stimulation followed by latency periods of 0, 30, 45, or 60 s. Milking characteristics were recorded. Total milk yield, main milking time and average milk flow rate did not differ between treatments if the degree of udder filling at the start of milking was >40% of the maximum storage capacity. However, if the udder filling was <40%, main milking time was decreased with the duration of a latency period up to 45 s, independent of duration of pre-stimulation. Average milk flow at an udder filling of <40% was highest after a pre-stimulation of 45 s followed by a latency period of another 45 s. In contrast, average milk flow reached its lowest values at a pre-stimulation of 15 s without additional latency period. However, average milk flow after a 15-s pre-stimulation increased with increasing latency period. In conclusion, a very short pre-stimulation when followed by a latency period up to 45 s before teat cup attachment remains a suitable alternative for continuous stimulation to induce milk ejection.

Haematological parameters are normal in dominant white Franches-Montagnes horses carrying a KIT mutation

The KIT receptor protein-tyrosine kinase plays an important role during embryonic development. Activation of KIT is crucial for the development of various cell lineages such as melanoblasts, stem cells of the haematopoietic system, spermatogonia and intestinal cells of Cajal. In mice, many mutations in the Kit gene cause pigmentation disorders accompanied by pleiotropic effects on blood cells and male fertility. Previous work has demonstrated that dominant white Franches-Montagnes horses carry one copy of the KIT gene with the p.Y717X mutation. The targeted breeding of white horses would be ethically questionable if white horses were known to suffer from anaemia or leukopenia. The present study demonstrates that no statistically significant differences in peripheral blood parameters are detectable between dominant white and solid-coloured Franches-Montagnes horses. The data indicate that KIT mutations may have different effects in mice, pigs, and horses. The KIT p.Y717X mutation does not have a major negative effect on the haematopoietic system of dominant white horses.
