p53 as the main traffic controller of the cell signaling network
2010
Among different pathological conditions that affect human beings, cancer has received a great deal of attention primarily because it leads to significant morbidity and mortality. This is essentially due to increasing world-wide incidence of this disease and the inability to discover the cause and molecular mechanisms by which normal human cells acquire the characteristics that define cancer cells. Since the discovery of p53 over a quarter of a century ago, it is now recognized that virtually all cell fate pathways of live cells and the decision to die are under the control of p53. Such extensive involvement indicates that p53 protein is acting as a major traffic controller in the cell signa…
La tinaja de Caná
2005
Los curiosos avatares de un vaso de reflejo dorado que hoy en día se conserva en el Museo Nacional de Estocolmo nos permiten recordar las conexiones entre la alquimia y la cerámica a lo largo de la historia. (A)
La loza decorada en España
2008
La loza decorada apareció en la península ibérica bajo la dominación musulmana durante el califato de Córdoba. La técnica oriental de las cubiertas de plomo decoradas con óxidos metálicos, incluso opacificadas con estaño, se produjeron en los talleres de la corte y de ahí se difundieron hacia los mercados urbanos. En los reinos cristianos peninsulares, la transferencia técnica e incluso su uso en la mesa, no se hizo hasta la segunda mitad del siglo XIII. Sin duda, la conquista de los territorios musulmanes y la deportación de alfareros musulmanes hacia las ciudades permitió asimilar el uso de la loza. A lo largo de los siglos se dieron diferentes influencias estilísticas: en el medioevo la …

Über methylsubstituierte polyphenylene
1951
Es werden Versuche geschildert, die zur Darstellung von loslichen, stabchenformigen Molekulen, namlich para-verketteten, methylsubstituierten Polyphenylenen fuhren sollen. 4.4′-Dijod-3.3′-dimethyl-diphenyl wurde nach Ullmann mit Kupferpulver unter verschiedenen Bedingungen kondensiert und die erhaltenen loslichen, methylierten Polyphenylene fraktioniert. Ultrazentrifugale und osmotische Messungen ergeben fur die hochstmolekularen Fraktionen Molekulargewichte bis zu 300000. Kryoskopische Untersuchungen liefern anomale Molekulargewichte. Die Ergebnisse der Viskositats-, Sedimentations und Diffusionsmessungen werden im Hinblick auf die Gestalt der Molekule diskutiert. Die unter den angewandten…
A Non-world : Chinese Perceptions of the Western International Order
2019
As the West struggles, China, economically and politically stable, has increased its criticism toward the Western-led international order. According to Chinese arguments, the ongoing decade has demonstrated that the Western liberal international order is no more capable of solving the troubles of the globalizing world. It is as if the Western political imagination has run out of steam and it is now the responsibility of China to take the lead in stabilizing the world. On the side of the official statements, Chinese theorists of world politics are envisioning a new alternative world order, which would be based on a historical, sinocentric system that was in place in East Asia for thousands o…
Tianxia, Kiina ja hegemonisen vakauden teoria
2020
Kiinassa on 2000-luvulla rakennettu kiinalaista maailmanpolitiikan teoriaa, joka ammentaa lännen sijaan Kiinan omasta historiasta ja älyllisestä traditiosta. Yksi eniten huomiota herättäneistä teoreettisista aloitteista on niin kutsuttu tianxia-teoria, jonka mukaan nykyinen kansallisvaltioihin pohjautuva kansainvälinen järjestelmä tulisi korvata Kiinan historiasta löytyvän tianxia-mallin mukaisella keskuskjohdetulla maailmanvaltiolla. Artikkeli vertaa tianxia-teoriaa hegemonisen vakauden teorian erilaisiin variantteihin ja esittää, että lähemmin tarkasteltuna tianxia-teorian ajatukset ovat varsin samankaltaisia jo vakiintuneiden teorioiden ajatusten kanssa. Tianxia theory is one of the most…
Analytical-numerical methods for investigation of hidden oscillations in nonlinear control systems
2011
The method of harmonic linearization, numerical methods, and the applied bifurcation the- ory together discover new opportunities for analysis of oscillations of control systems. In the present survey analytical-numerical algorithms for hidden oscillation localization are discussed. Examples of hidden attrac- tor localization in Chua's circuit and counterexamples construction to Aizerman's conjecture and Kalman's conjecture are considered.
