As the main result justifying the conclusions in [Andres, J., Kubáček, L., Machalová, J., Tučková, M.: Optimization of parameters in the Menzerath–Altmann law Acta Univ. Palacki. Olomuc., Fac. rer. nat., Math. 51, 1 (2012), 5–27.], the theorem is presented enunciating that the English original of Poe’s celebrated poem Raven is a language fractal only w.r.t. the application of the simplest truncated formulas of the Menzerath–Altmann law, but not w.r.t. other applied formulas under our consideration. Moreover, the related degree of semanticity is calculated in these cases, including the naive intervals of such a degree. A suitability of the applied formulas is discussed from the point of view of a verbal version of the Menzerath–Altmann law (i.e. the tendency of the approximating functions is to be decreasing) and by means of quantitative criteria characterizing the accuracy of fitted data. Our discussion extends the traditional approaches to the Menzerath–Altmann law

Optimization of parameters in the Menzerath–Altmann law
No full textsummary:Four formulas of the Menzerath–Altmann law are tested from the point of view of their applicability and suitability. The accuracy of related approximations of measured data is examined by the least square method at first. Then the accuracy of calculated parameters in the formulas under consideration is compared statistically. The influence of neglecting parameter is investigated as well. Finally, the obtained results are discussed by means of an illustrative example from quantitative linguistics
Disturbance of cerebral function in people exposed to drinking water contaminated with aluminium sulphate: retrospective study of the Camelford water incident
No full textObjective: To establish whether people exposed to drinking water contaminated with 20 tonnes of aluminium sulphate in the Camelford area of Cornwall in the south west of England in July 1988 had suffered organic brain damage as opposed to psychological trauma only.
Design: Retrospective study of affected people.
Participants: 55 affected people and 15 siblings nearest in age to one of the group but who had not been exposed to the contaminated water were studied.
Main outcome measures: Various clinical and psychological tests to determine medical condition and anxiety levels in affected people. Assessment of premorbid IQ (pFSIQ) with the national adult reading test, a computerised battery of psychomotor testing, and measurement of the difference in latencies between the flash and pattern visual evoked potentials in all participants.
Results: The mean (SE) pFSIQ was above average at 114.4 (1.1). The most sensitive of the psychomotor tests for organic brain disease was the symbol digit coding (SDC) test (normal score 100, abnormal less than 85). Participants performed less well on this test (54.5 (6.0)) than expected from their pFSIQ (Pless than 0.0001) and a little less poorly on the averaged less discriminating tests within the battery (86.1 (2.5), Pless than 0.0001). In a comparison with the 15 sibling pairs (affected people's age 41.0 (3.3) years vsibling age of 42.7 (3.1) years (P=0.36) the exposed people had similar pFSIQ (114.7 (2.1)) to their siblings (116.3 (2.1), (P=0.59) but performed badly on the symbol digit coding test (51.8 (16.6)) v(87.5 (4.9) for siblings, P=0.03). The flash-pattern differences in exposed people were greater than in 42 unrelated control subjects of similar age (27.33 (1.64) ms v18.57 (1.47) ms, P=0.0002). The 15 unexposed siblings had significantly better flash-pattern differences than their affected siblings (13.4 (2.4) ms v29.6 (2.9) ms, P=0.0002). No effect of anxiety could be shown on these measurements from the analysis of the anxiety scores of exposed people.
Conclusion: People who were exposed to the contaminated water at Camelford suffered considerable damage to cerebral function, which was not related to anxiety. Follow up studies would be required to determine the longer term prognosis for affected individuals

Algunos estudios sobre succionoxidasa
No full textSe ha encontrado un grupo de nuevas substancias: verseno, pirofosfatoy 8 hidroxiquinolina, que activan las preparaciones de succinoxidasaen buffer de fosfato, y las reactivan en buffer de bicarbonato. La pureza del substrato (succinato de sodio) es crítica. Purificándolose llegó a preparados que, activados con verseno, -el más poderosode los compuestos ensayados-, presentaban un QO2 (µl O2/hora/mgrde residuo seco libre de grasa) de 900. El verseno presenta un máximo de actividad cuando su concentraciónen el líquido del frasco manométrico es de 0.1 mgr/ml. Si la enzima se lava con agua destilada en recipiente de vidrioen vez de agua corriente, su actividad disminuye, pero puede ser todavíaactivada con verseno hasta su valor normal. La inactivación conbicarbonato se hace proporcionalmente menor. Se ha encontrado que la anserina activa ligeramente la enzima. Sales de calcio, aluminio y cromo activan la enzima con formaciónde tenues precipitados. Estos desaparecen al agregar verseno sin quese altere la actividad. Se ha encontrado que se obtienen condiciones óptimas para la actividadde la enzima cuando se la mantiene en una solución de bufferde fosfato 0.1 M adicionada con cloruro de potasio 0.1 M. Se discute el mecanismo de los activadores mencionados. Esto puedeatribuirse a su poder de complejantes de metales pesados. Efectos deadsorción como los mencionados por Keilin y Hartree se descartan. Sinembargo, otros efectos de carácter coloidal podrían ser importantes. Los resultados obtenidos parecerían indicar que la enzima poseeíntimamente ligados a ella, algún metal inhibidor de la misma, y otro metalo componente activador que sería eliminado por repetidos lavados delmúsculo de corazón de caballo con agua destilada en recipiente de vidrio.Fil: Liebeschütz de Altmann, Susana M..

Non-Hamiltonian dynamics in optical microcavities resulting from wave-inspired corrections to geometric optics
No full textWe introduce and investigate billiard systems with an adjusted ray dynamics that accounts for modifications of the conventional reflection of rays due to universal wave effects. We show that even small modifications of the specular reflection law have dramatic consequences on the phase space of classical billiards. These include the creation of regions of non-Hamiltonian dynamics, the breakdown of symmetries, and changes in the stability and morphology of periodic orbits. Focusing on optical microcavities, we show that our adjusted dynamics provides the missing ray counterpart to previously observed wave phenomena and we describe how to observe its signatures in experiments. Our findings also apply to acoustic and ultrasound waves and are important in all situations where wavelengths are comparable to system sizes, an increasingly likely situation considering the systematic reduction of the size of electronic and photonic devices
