Observations of the de Haas-van Alpen Effect in Arsenic
No full textTitle: Observations of the de Haas-van Alpen Effect in Arsenic, Author: John Vanderkooy, Location: ThodeSemimetallic arsenic has been studied by magneto-resistance
methods and measurement of the de Haas-van Alphen effect using torque and magneto-thermal measurements. Several modifications have been made in the conventional torque techniques. An important cause of nonlinear effects in the torque experiments is presented and compared to other mechanisms for nonlinearities. The Fermi surface of arsenic as determined experimentally is shown to be in good agreement with recent
theoretical calculations which were partially guided by the experiments.ThesisDoctor of Philosophy (PhD
Shubnikov–de Haas Effect in the Metallic State of Na0.3CoO2
No full textShubnikov–de Haas oscillations for two well-defined frequencies, corresponding, respectively, to areas of 0.8 and 1.36% of the first Brillouin zone, were observed in single crystals of Na0.3CoO2. The existence of Na superstructures in Na0.3CoO2, coupled with this observation, suggests the possibility that the periods are due to the reconstruction of the large Fermi surface around the ? point. An alternative interpretation in terms of the long sought-after ?g? pockets is also considered but found to be incompatible with existing specific heat data.Kavli Institute of NanoscienceApplied Science
The joy of knowing pete: much was said, yet no words were spoken, by Hazel Morgan. YouCaxton publications. 2022
No full textHazel Morgan wrote her first book, Through Pete's Eyes, about her son's early childhood. In this second book she makes no attempt to be his voice but tells us her own stories, as she remembers her son with love. He was born in 1977 and lived for 18 years. The family had the benefit of living in a tied bungalow in the grounds of a school where his father, Andy, was deputy head. Pete was communicative but did not use words; he could not write his own story in text. This is a book is written through a mother's eyes about how her family learnt to live alongside Down syndrome, and profound and multiple learning disabilities. It eloquently describes this experience, and how this experience helps the author to see the world differently. Through her we learn wisdom from Pete. His adventures became the fondly remembered adventures of the whole family, of his parents and of his brother, Philip
Small-angle Shubnikov-de Haas measurements in a 2D electron system: The effect of a strong in-plane magnetic field
No full textMeasurements in magnetic fields applied at small angles relative to the electron plane in silicon MOSFETs indicate a factor of two increase of the frequency of Shubnikov-de Haas oscillations at H>H_{sat}. This signals the onset of full spin polarization above H_{sat}, the parallel field above which the resistivity saturates to a constant value.Applied Science

No full textEste articulo propone una interesante lectura de la guerra a través del registro arqueológico donde se revela que ésta no es un estado permanente entre las sociedades humanas, por lo tanto subyace el interés por replantear la idea que la guerra es connatural al ser humano. En efecto, el autor se soporta en el registro arqueológico de la región Anasazi, al suroccidente de los Estados Unidos, y en datos arqueológicos del Este de Norteamérica para demostrar cómo las sociedades que poblaron estas latitudes experimentaron importantes períodos de paz. En última instancia, el artículo revela la importancia de la arqueología para superar la percepción de que la guerra es el medio más recurrente de interacción entre las sociedades humanas.This article propases an interesting reading on war through archeological data, where it is shown that it isn't a permanent state between human societies, therefore it is necessary to restate the idea that war is connatural to human beings. In effect the author bases his study on archeological data of the Anasazi area in the southwestern part of the United States and the eastern part of North America, to demonstrate how the societies that settled in these latitudes went through time periods of peace. In this last instance, the article reveals the importance of archeology to overcome the perception that war is the most recurrent manner of interaction between human societies
