Legelőn tartott angus borjak testtömeg-gyarapodásának vizsgálata a csapadékmennyiség függvényében
No full textA húsmarhatartás napjainkban leginkább legelőre alapozott tartásmód mellett sikeres. Az angus fajta remekül alkalmazható ebben a rendszerben, mivel a tartástechnológiára igénytelen, extenzív fajta. A dolgozatban az adonyi ANGUS KFT. telepén, az ott lévő legelőkön tartott angus borjakat vizsgálata készült el. A csapadékmennyiség hatását elemeztem az állomány átlagos napi súlygyarapodására és a 205 napos korrigált testtömegére. Az adatok, amelyekkel dolgoztunk 2010-től a 2016-os év végéig álltak rendelkezésünkre. Az eredményekből megállapítható, hogy a csapadékmennyiség befolyással bír az állomány súlyadatainak alakulására.állattenyésztő mérnökBSc/B
The singin lass : a reflection on the life of the poet Marion Angus (1865-1946) in the form of an account of her life and work, and three extracts from 'Blackthorn', a novel
No full textPart 1 of this thesis comprises a biography which, for the first time, places Marion Angus within her historical, family and social context. A version of this was published as the introduction to my edited collection The Singin Lass: Selected Work of Marion Angus (Polygon, 2006).
Assumptions made about the poet's activities and attitudes derive from critical reading of archival material: her published 'diaries', letters and prose, as well as her poetry. The appraisal of her work places it within literary contexts. The development of her linguistic awareness of the Scots language is traced and the extent of her commitment to it noted.
I conclude that assessment of her work has frequently been affected by erroneous judgements about her lifestyle and that the poetry, which has greater depth than it sometimes is given credit for, illuminates her struggle rather than defines her character. Her strength and resilience, as well as her contribution to Scots literature, should be respected and admired.
Part II comprises three extracts from Blackthorn, a novel based on aspects of the life and work of Marion Angus. My starting point was the marked contrast between her earlier prose and her later poetry. This, I believe, reflects an actual family crisis which is central to my narrative. The extracts presented here (dated 1900, 1930 and 1945-46) present a credible alternative to inaccurate assumptions which were made about her life. I explore two actual significant relationships in her life: with a sister who becomes wholly dependent on her, and with a younger friend who looks after her in her final year. In the absence of any firm evidence of lovers, I speculate on other relationships
Angus Maddison and Development Economics
No full textThis paper was prepared for the Angus Maddison Memorial conference, held in November 2010 at the International Institute of Social History in Amsterdam. The paper reflects on Angus Maddison's contributions to development economics. It focuses on the following issues: 1. quantification in development economics and the framework of proximate and ultimate causality in growth and development; 2 the debate about levels of GDP per capita in the middle of the eighteenth century; 3 Maddison versus the Malthusians; 4 measurement of Chinese Economic Performance in the long run; 5. the impact of Western expansion on the non-Western world and 6. the role of institutions in economic development.Economic Growth, Development Economics, GDP per capita, China, Western Expansion, Institutions
A re-examination of the West European species of Boreonectes Angus, 2010, with particular reference to B. multilineatus (Falkenström, 1922) (Coleoptera, Dytiscidae)
No full textThe West European species of Boreonectes Angus, 2010 are reviewed. B. multilineatus (Falkenström, 1922) is shown to be widely distributed in the Pyrenees, where it is the only species known to occur. The chromosomes of all five west European species are found to have, in addition their different numbers of chromosomes, differences in the number and locations of secondary constrictions, and in some cases, the number of chromosomes with clear centromeric C-bands. The level of differences between the chromosomes of the species is in stark contrast with the very slight genetic (DNA) differences between them and this suggests that chromosome differentiation may have been a driver of speciation. Two of the species, B. griseostriatus (De Geer, 1774) and B. multilineatus, have distributions extending northwards as far as Arctic Scandinavia. It is pointed out that, while these northern areas now constitute the major portions of their ranges, they must be of fairly recent origins as most of the area would have been covered by ice sheets and therefore not habitable during the glacial maximum of the Last Glaciation. This contrasts with the situation in the area of the Central European mountains where fossil faunas, including Boreonectes, are known. B. griseostriatus, identifiable to species by its parameres, was present in the Woolly Rhinoceros site at Starunia in the Western Ukraine, and this fauna is discussed as well as an English fauna of similar age
Genomic structure and selection history across Angus populations worldwide: insights from ROH, selection mapping, and functional analyses.
No full textAngus cattle, originally from Scotland, have been selectively bred for over 400 years, making them one of the most prominent beef breeds globally. Known for their adaptability, natural polled traits, and high-quality beef, Angus cattle have been intensively selected for growth, body size, and feed efficiency. This study investigates the genetic diversity, selection history, and key genomic regions across five Angus populations from the USA, Canada, Australia, Brazil, and Red Angus of America. Genomic data from 71,283 animals born between 1961 and 2024 were analyzed using Principal Component Analysis (PCA), phylogenetic tree construction, and Runs of Homozygosity (ROH), with the Generation Proxy Selection Mapping (GPSM) approach used to assess selection history. Functional annotation identified candidate genes and pathways related to selection. Our analysis revealed both similarities and differences across populations. The PCA and FST metrics showed minimal differentiation between the American, Canadian, Australian, and Brazilian populations, with greater differentiation observed in the Red Angus population. The ROH analysis revealed that the Brazilian population had the highest number of ROHs. The ROH islands identified on BTA8 and BTA13 in the American and Australian populations were linked to traits like body weight, marbling, and tenderness. The GPSM identified significant markers associated with body weight and growth in all populations, reflecting ongoing selection pressures. This study highlights the potential of genomics to improve our understanding of Angus cattle’s genetic architecture and selection history. It underscores the feasibility of integrating global populations for more accurate genomic evaluations, enhancing genetic predictions, and supporting sustainable beef production worldwide
