In most of the tests, the results improved the more the subjects drank in a week. Overall, the heaviest drinkers men who drank more than 241 grams of alcohol per week typically performed 10 percent to 30 percent better than other drinkers. . . .

Membre du bureau des longitudes, il remplace Le Verrier (1811-1877) à la direction de l'observatoire de Paris (1870) où ce dernier fut évincé, victime de ses méthodes de gestion. Delaunay est mort noyé lors d'une promenade en barque. l'École Royale des Mines de Paris fut fondée en 1783 par arrêté du roi Louis XVI sous l'égide de Balthazar Georges Sage, chimiste et minéralogiste. Ce dernier fut le premier directeur de cette école formant des ingénieurs civils de haut niveau aux compétences multiples (géologie, thermodynamique, énergétique, mécanique).

Extractions: On real numbers generated by finite automata The b -adic expansion of any rational number is eventually periodic, but how regular or random (depending on the viewpoint) is the b -adic expansion of an irrational algebraic number? It seems that this natural question has been first addressed by Borel in 1950, who made the conjecture that such an expansion should satisfy some of the laws shared by almost all real numbers. Algebraic irrationals are thus expected to be "rather complex" in a probabilistic framework. In 1965, Hartmanis and Stearns proposed an alternative approach of the notion of complexity of real numbers, by emphasizing the quantitative aspect of the notion of calculability introduced by Turing. According to them, a real number is said to be computable in time T n ) if there exists a multitape Turing machine which gives the first n -th terms of its binary expansion in (at most) T n ) operations. The "simplest" real numbers in that sense, that is, for which one can choose T n O n ), are said to computable in real time. The problem of Hartmanis and Stearns, to which a negative answer is expected, is the following: do there exist irrational algebraic numbers which are computable in real time?

Extractions: Un alumno no es un recipiente que hay que llenar de conocimientos, sino una antorcha que hay que encender. Prof. Delone Para algunos estudiantes de primaria y secundaria hay una materia con la cual, por más que se esfuerzan, no logran congeniar: las matemáticas . No todos los alumnos tienen esta dificultad: algunos las disfrutan tanto que exigen aprenderlas y ejercitarse más, convirtiéndose en un reto tanto para sus maestros como para los interesados en elevar la calidad de la educación. El pasado 30 de septiembre los representantes de México consiguieron el tercer lugar dentro de las Olimpiadas Iberoamericana de Matemáticas, superados sólo por los de Brasil y de Argentina. El representativo nacional estuvo integrado por David Mireles Morales, del Distrito Federal, quien obtuvo una medalla de oro, Miguel Raggi Pérez, de Michoacán, y Mauricio Chacón Tirado, de Chiapas, que ganaron medalla de plata, y Edgardo Roldán Pensado, del estado de Morelos, quien se hizo merecedor de una medalla de bronce. Pero fue David Mireles quien obtuvo el mayor puntaje de todos los participantes de la olimpiada. Pero, ¿qué es la Olimpiada de Matemáticas? Es un concurso que se realiza a escala internacional desde el año de 1934, organizado por Boris Nikolaevich

Ascent Of Belukha Mountain boris is filming our enthusiastic eyes. The whole of our route is within our sight. We face the Eastern Belukha peak and delone peak. http://altai-es.ukg.kz/en/d1_3.htm
Extractions: Ascent of Belukha mountain. August 1999. There are some rare places on earth where everyone feels himself at ease, places fabled beauty of which makes the heart stop beating. One of places is the Altai. Buddhists believe that it is the naval of the Earth, while Christian Old-Believers that it is Belovodye (White water). Rich in woods and rivers, honey, medicinal herb and ores, the extremely beautiful Altai is one of wonders of our planet. The Altai with its sacred two-headed Belukha Mt, the highest mountain in the whole of the Altai and Siberia, is not so popular with mountaineers as the Himalayas or the Pamirs . The advantage of Belukha Mt is that here you can make climbing tours ranged from the simplest to the most difficult. So you can enjoy the most exciting route to Belukha Mt from the southern side which was formerly close to foreigners.

Extractions: The wavevector-dependent susceptibility is the Fourier transform of the pair-correlation function revealing information on the structure of the model. The pair correlations in a planar Ising model can be calculated using quadratic recursion formulae. Aperiodicity can be introduced using Baxter's "Z-Invariance." We shall also introduce Ising models with aperiodic couplings based on de Bruijn's extension of the Fibonacci sequence. We shall prove an extension of a theorem of Tracy on the probability distribution implied and show some of our results. Helen Au-Yang An Ising model on a Penrose tiling based on a pentagrid is introduced. The Ising spins are on every other vertex of the Penrose tiling and the grid lines of the pentagrid are where the Yang-Baxter spectral parameters (rapidities) live. The pair correlation can be calculated by the techniques discussed in the previous talk. The joint probability for averaging over the two local environments of spins is reduced to linear programming. Finally results are shown for the wavevector-dependent susceptibility. David Damanik
