The Concept of Nature in the Thought of John Philoponus " We must now ask how this dynamic and relational way of thinking in his science, strictly in accordance with the nature or reality of things, affected Philoponos' theology in giving it a dynamic form in the doctrine of God and of salvation. "-Thomas F. Torrance in Theological and Natural Science, p. 6 This essay attempts to clarify the way the great 6 th Century Alexandrian Grammarian, John Philoponus, thought to employ a new concept of nature both in his philosophical or scientific and in his theological works. It is argued that, for Philoponus, there exists a real cognitive interface between the science of his theology and the theology of his philosophy, his physics, and his cosmology. It is further argued that, standing on the holy ground of this interface, we also may seek to understand the contingent order of the Universe as God's Creation as it comes to us from the Incarnate Word or Logos of the Almighty, the Father of the Lord Jesus Christ. I offer it in honor of the Very Reverend Professor Thomas F. Torrance. Part A The concept associated with the term 'Israel' means different things to different people. It signifies to different people of various epochs in the history of the world a spectrum of understandings. At Fuller Theological Seminary, the Bible scholar William Sanford LaSor, in his book entitled Israel, explored the meaning of this term across the centuries of Biblical history, concluding with some sense of mystery about the significance of the term in various times at various places in the history of the world. As a concept, the term possessed both differentiated signification as well as an integrative reference across the diverse contexts in which it is employed. A range of meanings was indicated when the whole concept was studied. The Bible reader knows well the reality that one term can refer in time and space to very different particulars, while connecting them all up as a whole. 1 In a similar way, the concept of Nature has meant different things to different people in various times and different contexts. Our efforts to understand the nature of the Universe, for instance, have required many adjustments, so to speak. The great Quantum physicist, Paul Dirac, could employ the term in his science with the assumption of the real solidity of its significance for his physics, even while knowing that the nature of fundamental particles has changed in our time dramatically. 2 Only a few years after Dirac, the Cambridge physicist, Roger Penrose, in his magisterial work entitled The Road to Reality, could write about the problem in understanding the nature of the wholeness and the particulars of this Universe: " True-so they might argue-we have been fortunate enough to stumble upon mathematical schemes that accord with Nature in remarkable ways, but the unity of Nature as a whole with some mathematical scheme can

Ultraviolet irradiation (254 nm) of immortal diploid human lymphoblasts killed cells, caused mutation at three genetic loci studied, and transiently inhibited 3H-TdR uptake into DNA. A shoulder of about 6 J/m2 and a D0 of 6 J/m2 was observed for survival. Mutation rose in a monotonic non-linear fashion through 6 J/m2; above 6 J/m2, complex behavior approximating a plateau in induced mutation was observed. Irradiation at 4.4 J/m2 caused a transient increase in the number of cells synthesizing DNA and a decrease in the rate of DNA synthesis relative to mock-irradiated controls. The parameter of rate of DNA synthesis per cell in DNA synthetic phase showed a rapid recovery toward control values between 2 and 4 h after irradiation and a slower recovery to control values by 22 h post-irradiation. Fractionated dose schedules were used to measure the effects of allowing a time interval between doses at nontoxic fluences (2.2 J/m2), moderately toxic fluences (8.8 J/m2) and toxic fluences (17...

Square-wave voltammetry was used for trace determination of azoxystrobin and dimoxystrobin in potatoes, grapes, and grape juice. Experimental conditions have been optimized to achieve simultaneous determination of these analytes using the hanging mercury drop electrode. Supporting electrolyte was HCl 0.1 mol L−1, and other optimized conditions were deposition potential (−300 mV), deposition time (30 s), amplitude (150 mV), frequency (150 Hz), and step height (2 mV). Azoxystrobin and dimoxystrobin redissolution peaks presented their maxima, respectively, at −928 mV and around −650 mV. Linear and homoscedastic analytical responses (r 2 > 0.99) have been observed. Limits of quantification as low as 119 µg L−1 (in grape juice) and 45 µg kg−1 (in potatoes and grapes) were found. A previous solid-phase extraction was necessary to eliminate interferences from potato and grape samples. For grape juice, no sample treatment was required. Satisfactory recoveries (from 72.3% to 96.7% for dimoxystrobin and from 81.7% to 102.3% for azoxystrobin) were found. Interferences from other strobilurins (piraclostrobin and picoxystrobin) were evaluated.

A lo largo de la Guerra Civil espa˜nola los cohetes fueron utilizados básicamente para lanzar propaganda sobre el enemigo y como elementos de señalización desde los campos de aviación republicanos. Pero hasta la fecha se desconocía que gracias a una iniciativa individual el bando republicano desarrollí durante el conflicto un cohete con la finalidad de convertirse en un verdadero proyectil de guerra. Bautizado por su inventor como “Torpedo Aéreo” y experimentado en 1937, nunca fue adoptado como arma en serie pese a encontrarse en un avanzado estado de desarrollo. En el presente art´ıculo se analizan las caracter´ısticas de este artefacto gracias al expediente localizado en al archivo Montserrat Tarradellas i Macià (Monasterio de Poblet) en la sección de
la Comisión de Industrias de Guerra de la Generalitat de Catalunya y se intenta también exponer por qué esta empresa, que hubiese sido una buena contribución y alternativa bélica para la República, no se llevó nunca a cabo.
