On distribution of pollen in lakes. [Translation from: Palynology in geological research in the Baltic Soviet Republics p113-119. Vilnius, 1973.]

Systematic investigations of the distribution of pollen in stationary water bodies until now have hardly been conducted. For clarification of the problem of how the pollen of different plants which falls into a lake is deposited in relation to its physical properties, the character of the lake, wind currents and other factors, pollen analyses were carried out of surface samples of the bottom sediments of 13 Lithuanian lakes. Lakes were selected of different sizes (areas from 2333 ha. to 8 ha.) and different depths, not uniformly overgrown, situated in different physico-geographic regions of Lithuania. As a result of the investigation, it was established that in the surface layer of the sediments of the lakes of Lithuania pollen of woody species predominates.

Could the library be dismantled/role of unique holdings in modern times

I have been asked by administration, how much of our collection could go into storage. They optimistically hoping for a room or two for faculty/staff offices, as some buildings need renovation or need to be closed due to safety issues. Clearly, much of the population believes that all/most library materials are available on-line ��� free. I will present the results of our survey���s of material held and available on-line and space ���freed��� thanks to archiving. How little space is freed.

Long-term natural acidification of upland sites in Cumbria: Evidence from post-glacial lake sediments

Studies by the Freshwater Biological Association over the last 25 years have supplied data relevant to the levels of acidity in local soils and water before the onset of industrial pollution and current interest in acid rain. This article reviews published analysis from cores of lake sediments, in or near the catchment of the River Duddon. Electron spin resonance spectra of humic acids and iodine values confirm evidence from pollen analysis for a history of progressive acidification of the source material of lake sediments since before 5000 radiocarbon years, in upland catchments of the Lake District. Processes involved included: removal of basic ions from soils by rainfall, the effects of which were intensified by removal by man of deciduous forest; acidification of soils and waters by decomposition products of Calluna and further acidification of waters by Sphagnum species which colonized habitats where drainage became impeded by paludification processes.

Nous sommes tousjours au dela : a nega����o narrative do sujeito modern em Sur des vers de Virgile (ensaios III, cap.V) de Michel de Motaigne

Investigando a apresenta����o das ideias em Sobre versos de Virg��lio, a tese demonstra como sua estrutura����o amb��gua, onde tudo �� constantemente negado por seus contr��rios, leva a um cont��nuo estado de confus��o e perplexidade, tornando imposs��vel a determina����o l��gica dos conceitos e conduzindo a um progressivo esvaziamento do texto enquanto signo direto do pensamento do autor. Por outro lado, partindo de uma perspectiva hermen��utica influenciada pela anatomia, a an��lise mostra que o uso sistem��tico e criativo das inst��ncias narrativas (autor, narrador, signat��rio), juntamente com a reunifica����o textual de diferentes Montaignes (presentes nos diversos est��gio editoriais do ensaio), acaba por dissolver a pr��pria no����o de identidade a si do autor, tendo por consequ��ncia imediata sua dissemina����o em v��rios sujeitos diversos e contradit��rios e, por fim, colocando em xeque a cl��ssica percep����o dos Ensaios com o nascimento da subjetividade moderna.
