Mechanische und Dauerhaftigkeitseigen-schaften von ternärem Mischbeton
Beton ist das am h ufigsten verwendete Material in Bauunternehmen, das aus nat rlichen Ressourcen hergestellt wird. Da die nat rlichen Ressourcen massiv verbraucht werden, um einen Beton-Dschungel zu schaffen. Um den Verbrauch nat rlicher Ressourcen zu verringern, m ssen wir einen alternativen Teilersatz f r Beton finden, der auch die Freisetzung von CO2 in die Atmosph re verringert, da bei der Herstellung einer Tonne Zement eine Tonne CO2 in die Atmosph re freigesetzt wird. Es wird also versucht, einen alternativen Teilersatz f r Zement zu finden. In der ersten Stufe wird der Zement teilweise durch 10%, 15%, 20%, 25%, 30% Flugasche, bezogen auf das Gewicht des Zements, ersetzt und der optimale Gehalt an Flugasche bestimmt. In der zweiten Phase wird der Zement teilweise durch den optimalen Gehalt an Flugasche und Eierschalenpulver (5%, 10%, 15% und 20%) ersetzt. Die Festigkeits- und Dauerhaftigkeitseigenschaften werden untersucht, um eine tern re Betonmischung f r die Klasse M60 zu entwickeln. Die Mischung mit 20 % Flugasche ergab eine maximale Druckfestigkeit von 77,22 N/mm2, w hrend die Kombination von 20 % Flugasche und 10 % Eierschalenpulver eine Festigkeit von 79,92 N/mm2 ergab. Im Vergleich zum Kontrollbeton erwies sich die Betonmischung als s urebest ndiger.
Propriétés mécaniques et de durabilité du béton de mélange ternaire
Le b ton est le mat riau le plus utilis dans les entreprises de construction et il est fabriqu partir de ressources naturelles. Les ressources naturelles sont consomm es massivement pour cr er une jungle de b ton. Pour r duire l'utilisation des ressources naturelles, nous devons trouver un substitut partiel au b ton, ce qui permet galement de r duire les missions de CO2 dans l'atmosph re, puisqu'une tonne de CO2 est rejet e dans l'atmosph re lors de la fabrication d'une tonne de ciment. On tente donc de trouver un substitut partiel au ciment. Dans un premier temps, le ciment est partiellement remplac par 10 %, 15 %, 20 %, 25 %, 30 % de cendres volantes en poids de ciment, et la teneur optimale en cendres volantes est d termin e. Dans la deuxi me tape, le ciment est partiellement remplac par une teneur optimale en cendres volantes et en poudre de coquille d'oeuf (5 %, 10 %, 15 % et 20 %). Les propri t s de r sistance et de durabilit sont tudi es afin d' tablir un m lange ternaire de b ton pour le grade M60. Le m lange de cendres volantes 20% a obtenu une r sistance la compression maximale de 77,22 N/mm2, tandis que la combinaison de cendres volantes 20% et de poudre de coquille d'oeuf 10% a donn une r sistance de 79,92 N/mm2, compar e au b ton de contr le, le m lange de b ton s'est av r plus r sistant l'acidit .

Every scientific subject probably conceals unexplored or little investigated strata, which may show up at the proper time when favourable conditions coincide (practical demands, a circle of scientists prepared to recognize the novelty and capable of giving impetus to the development of a new theory, etc.). Something like this occurred in early seventies for magnetohydrodynamics, which at the time was considered to be a relatively complete branch of hydro­ dynamics with no apparent broad, unexplored areas. It was unexpectedly realized that, in addition to the traditional methods of affecting an electrically conducting medium, there is yet another way, one which subsequently lead to a new direction in magnetohydrodynamics. In the Soviet scientific literature this direction has been termed 'electrically induced vortex flows', the essence of which are hydrodynamic effects due to the interaction of an electric current passing through the fluid with its own magnetic field. It cannot be said that this direction was created ex nihilo: individual studies related to the flows driven in a current-carrying medium in the absence of external magnetic fields appeared in the sixties; in the thirties the flows them­ selves were known to take place within electrical arcs; and yet the first observa­ tions on the behaviour of liquid current-carrying conductors were made at the beginning of this century.

This book reviews the interrelation between the structure and adsorption properties of water and nitrogen vapours and Ni, Cu and Ag cations of the chitosan samples modified by freeze-drying after precipitation with NaOH or Na2CO3 or drying in air, as well as cross-linking. The investigations by IR spectroscopy, X-ray diffraction and pulsed NMR show the influence of the preliminary treatments on the Supramolecular structure. The more ordered structure is observed in the freeze-dried samples of chitosan compared with the air-dried sample. The parameters of the porous structure of the chitosan samples calculated from the isotherms of water vapours adsorption and the nitrogen vapours low temperature adsorption are compared. It is revealed that the isotherms of water vapours adsorption on the chitosan samples are more sensitive to the structural modification of polymers.

This hands-on manual provides Latinas with the tools they need to succeed at work by examining some of the societal and cultural obstacles that hinder their progress.Despite being 20 million strong, Latinas represent America's most undervalued human resource. This career guide is the only one of its kind to focus specifically on empowering the working women of the Latina community to embrace success and build skills for workplace advancement.The Latina's Guide to Success in the Workplace explores the complexity of the Hispanic/Latino identity and the impact of this culture on professional mobility. The author asserts that there are five obstacles which Latinas confront within their own belief system: the idea that women do not need an education; the assumption that the needs of men come first; a belief that it is sinful to desire money; the opinion that Latinas should not be ambitious; and the mindset that successful women in the United States lose their femininity. Throughout the book, up-to-date research, case studies, and inspirational interviews offer strategies for overcoming the cultural factors that limit Latinas and providing a roadmap for achieving success.

A volume of four new plays as part of the RSC’s Midsummer Mischief by Alice Birch, E. V. Crowe, Timberlake Wertenbaker and Abi Zakarian.The writers had the famous quote by Laurel Thatcher Ulrich, “Well-behaved women seldom make history” as an initial provocation and each writer has responded to this line in a unique and distinctive way.Contents:The Ant and the Cicada by Timberlake WertenbakerA mysterious investor has set his sights on a prime piece of Greek real estate. Owned by two sisters whose lives and beliefs are at odds, and with debts rising all the time, the property's future is uncertain. In a Greek tragedy, everybody loses.Through the struggle between two very different sisters for control of their family home, Timberlake Wertenbaker's new play explores why we are willing to let the home of art and democracy crumble as the rest of Europe looks on.Revolt. She said. Revolt again. by Alice BirchYou are expected to behave… Use the right words Act appropriately Don't break the rules Just behave This play is not well behavedAlice Birch examines the language, behaviour and forces that shape women in the 21st century and asks what's stopping us from doing something truly radical to change them.Winner of the George Devine Award for Most Promising New Playwright 2014I can hear you by E.V. CroweTommy is dead. It's always tragic when they die young.People have posted loads of nice stuff on his Facebook page. His sister Ruth has returned for the funeral and wants to get it just right. Proper cutlery and a good spread. The send-off he deserved, and certainly better than they managed when mum died.The following Sunday Ruth's plans to leave again are interrupted as the doorbell rings and in walks a still very much dead, Tommy.E.V. Crowe's naturalistic supernatural play examines what the possibilities are for the women in Tommy's family, and questions if it's as easy for everyone to reveal what it is they want.This is not an exit by Abi ZakarianYou wake up, tied to a radiator. Your hands are bound and there is a bag over your head.You know you should fight, but you don't know how or against whom. But you can't have it all: where would you put it?Abi Zakarian's new play is a funny and ferocious drama about the absurdity at the heart of modern womanhood, and what really stands in the way of fulfilment.
