Tori embedded in S³ with dense asymptotic lines

In this paper are given examples of tori T² embedded in S³ with all their asymptotic lines dense.

Clifford Geertz, 1926-2006: Meaning, method, and Indonesian economic history

Clifford Geertz was best known for his pioneering excursions into symbolic or interpretive anthropology, especially in relation to Indonesia. Less well recognised are his stimulating explorations of the modern economic history of Indonesia. His thinking on the interplay of economics and culture was most fully and vigorously expounded in Agricultural Involution. That book deployed a succinctly packaged past in order to solve a pressing contemporary puzzle, Java's enduring rural poverty and apparent social immobility. Initially greeted with acclaim, later and ironically the book stimulated the deep and multi-layered research that in fact led to the eventual rejection of Geertz's central contentions. But the veracity or otherwise of Geertz's inventive characterisation of Indonesian economic development now seems irrelevant; what is profoundly important is the extraordinary stimulus he gave to a generation of scholars to explore Indonesia's modern economic history with a depth and intensity previously unimaginable.

Alguns desafios de Clifford Pickover : dos números vampiros aos quadrados mágicos

Clifford Alan Pickover nasceu a 15 de agosto de 1957. Este americano é um reconhecido divulgador da Ciência e da Matemática, tendo publicado até ao momento mais de quarenta livros em mais de uma dúzia de línguas. (...) O principal interesse de Pickover está em encontrar novas maneiras de expandir a criatividade, estabelecendo conexões entre áreas aparentemente díspares do esforço humano, como a Arte, a Ciência e a Matemática. (...) Em 1994, Pickover introduziu uma nova classe de números, de certa forma peculiar: os números vampiros. (...) Um número vampiro é um número natural, v, com um número par de algarismos (n), que pode ser escrito como um produto de dois números naturais, x e y, cada um com metade do número de algarismos (n/2) e de forma a que os algarismos utilizados sejam os mesmos (eventualmente escritos por ordem diferente). (...) Na fatorização de um número vampiro, apenas um dos fatores pode ser múltiplo de 10 (ou seja, apenas um dos fatores pode ter o 0 como algarismo das unidades). Assim, 1260 é um número vampiro uma vez que 1260 = 21x60, mas 126 000 já não é um número vampiro apesar de 126 000 = 210x600. Isto porque, no segundo caso, ambos os fatores são múltiplos de 10. (...) Pickover também é adepto de quadrados mágicos. (...)

Avaliação da torção miocárdica, por Spekle Tracking, em doentes com HTA

Mestrado em Tecnologia de Diagnóstico e Intervenção Cardiovascular - Ramo de especialização: Ultrassonografia Cardiovascular

Torção Anexial

Adnexal torsion is a rare event whose diagnosis requires a high degree of suspicion since its presentation is clinical and laboratory nonspecific. Ultrasound constitute the first-line exam in the imaging evaluation and timely surgical treatment, with detorsion, is mandatory to allow the preservation of the structures involved. The effectiveness of preventive measures of recurrence is yet to be determined. In this paper, in addition to a literature review, the authors present a new imaging finding and propose a flowchart for therapeutic decision.

Recurrence relations for Clifford algebra-valued orthogonal polynomials

The theory of orthogonal polynomials of one real or complex variable is well established as well as its generalization for the multidimensional case. Hypercomplex function theory (or Clifford analysis) provides an alternative approach to deal with higher dimensions. In this context, we study systems of orthogonal polynomials of a hypercomplex variable with values in a Clifford algebra and prove some of their properties.

Ixodes (Haemixodes) longiscutatum Boero (new status) and I. (H.) uruguayensis Kohls & Clifford, a new synonym of I. (H.) longiscutatum (Acari: Ixodidae)

Females of Ixodes (Haemixodes) uruguayensis Kohls & Clifford, 1967, a species whose adults were unknown until the present, were obtained in the laboratory from engorged nymphs collected on rodents (Scapteromys tumidus and Oxymycterus nasutus) in the counties of Maldonado and San José, Uruguay. Morphological characters of these females were identical to those given in the description of the female of Ixodes longiscutatum Boero, 1944. I. uruguayensis is, thus, relegated to a junior subjective synonym of I. longiscutatum. However, because of the unique morphological characters of the immature stages, the validity of the subgenus Haemixodes Kohls & Clifford, 1967 is not questioned. Therefore, the new status of Ixodes (Haemixodes) uruguayensis Kohls & Clifford, 1967 is Ixodes (Haemixodes) longiscutatum Boero, 1944.
