Siliceous microfossil distribution in the surficial sediments of Lake Baikal

Examination of surficial sediments at 16 stations shows minor, but consistent differences in the numbers and kinds of siliceous microfossils deposited in different regions of Lake Baikal. There is a general north-south decreasing trend in total microfossil abundance on a weight basis. Endemic plankton diatom species are the most abundant component of assemblages at all stations. Chrysophyte cysts are present at all stations, but most forms are more abundant at northern stations. Non-endemic plankton diatom species are most abundant at southern stations. Small numbers of benthic diatoms and sponge spicules are found in all samples. Although low numbers are present in offshore sediments, the benthic diatom flora is very diverse. Principal components analysis confirms primary north-south abundance trends and suggests further differentiation by station location and depth.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/43071/1/10933_2004_Article_BF00682594.pd

Féminisme français : Fait, Fiction

What gives power to an idea? What makes it real in the hearts and minds of people who believe in it? What creates the desire to struggle for this idea, an ethereal and elusive conception? These are the questions that must be considered by philosophers, by those who believe enough in an idea to make it a reality. It was the mission of feminists in France since the beginning of the 19th century. For them, feminism was not a movement that had a beginning and an end, it was a force, present in the world since the creation of the sexes. Feminism was not just a movement for the liberation of women, it was a search for a united identity, an identity capable of inciting change, capable of leaving a legacy. Feminism was present as a seed in the mind of every woman who was oppressed. But to grow, to become tangible, this seed needed an impulse. She needed a catalyst that could upset the idea and disturb the world of peace he was getting used to. Feminism in France took shape because society could no longer ignore women as citizens, as individuals, as indispensable for the continuation of life. This achievement has changed everything. It changes the 19th century, and with modern times
