Magnetic reversal modes in multisegmented nanowire arrays with long aspect ratio
E. A. Rando,S. Allende
Physics , 2015, DOI: 10.1063/1.4926377
Abstract: A detailed numerical analysis of the magnetization reversal processes in multisegmented nanowire arrays was developed. The nanowires have a long aspect ratio and are formed by magnetic and non-magnetic sections alternately arranged in such a way that the array resembles magnetic layers separated by non-magnetic layers. Attention has been focused on the influence of magnetostatic interaction in the magnetic pattern formation of these magnetic nanostructures. Results from a magnetic correlation function among layers show that three different reversal modes can be detected depending on the number and distance between the magnetic segments. As a consequence of the different reversal modes, a non-monotonic behavior of the annihilation field in function of the distance between the layers is evidenced. Thus, these results are important for the production of magnetic devices with multisegmented nanowire arrays.

Abstract: one of the most difficult tasks in forensic pathology is deciding the origin and the cause of death after the autopsy when those issues are unclear or debatable. a technically perfect autopsy is a necessary but not a sufficient condition to adequately fulfil this decision. the present paper clearly defines the concepts of cause and mechanism of death, natural and violent death. we review many aspects related to the diagnosis of the origin and cause of death, especially the current approach of the value of autopsy in the diagnosis, the interaction between trauma and disease, the doctrine of causation, the use of icd- 10, the so-called manner of death, the psychological autopsy, the negative autopsy and the origin of death from therapeutic complication, and so on., all of which are illustrated with relevant examples. we also discuss the limited role of the forensic pathologist in spain in determining the so-called manner of death. the conclusions include(s) a list of recommendations for the best performance of this work, including the abandonment of the so-called unacceptable causes of death -as cardiac arrest, cardiopulmonary arrest or brain death, and so on- and whenever possible the adoption of the classification of icd-10 and the standard paragraph in which the cause of death is informed (part i and ii), as proposed by the who international certificate of death. these conclusions intend to be a brief guide to provide a fair judicial outcome and enhance the forensic pathologist's credibility.

Abstract: Una de las tareas más difíciles en patología forense puede ser determinar, después de la autopsia, el origen y la causa de la muerte cuando dichos extremos no están claros o son discutibles. Una autopsia técnicamente perfecta es condición necesaria pero no suficiente para cumplir adecuadamente esta decisión. En el presente trabajo se delimitan claramente los conceptos de causa y mecanismo de muerte, muerte natural y muerte violenta. Se revisan muchos de los aspectos relacionados con el diagnóstico del origen y la causa de la muerte; especialmente el enfoque actual del valor de la autopsia en el diagnóstico, la interacción entre traumatismo y enfermedad, la doctrina de la causalidad, la utilización de la CIE-10, la llamada etiología médico-legal, la autopsia psicológica, la "autopsia blanca" o negativa y el origen de la muerte por complicaciones de la terapéutica, etc., todos ellos se ilustran con ejemplos de casos representativos. Se discute el limitado papel del patólogo forense en Espa a en la determinación de la denominada etiología médico-legal. Las conclusiones constituyen un conjunto de recomendaciones para el mejor cumplimiento de este trabajo, entre ellas el abandono de las denominadas causas de muerte inaceptables como parada cardiaca, parada cardiorrespiratoria o muerte cerebral, etc., la utilización siempre que sea posible de los diagnósticos de la CIE-10 y del formato del apartado de la causa de la muerte (parte I y II) del modelo internacional de certificado médico de causa de defunción de la OMS. Todo ello como guía breve que facilite un resultado judicial adecuado y aumente la credibilidad del patólogo forense.

Abstract: Introduction and aims. Balanced propofol sedation (BPS) administered by gastroenterologists has gained popularity in endoscopic procedures. Few studies exist about the safety of this approach during endosonography with fine needle aspiration (EUS-FNA). We assessed the safety of BPS in EUS-FNA. Materials and methods. 112 consecutive patients, referred to our unit to perform EUS-FNA, from February 2008 to December 2009, were sedated with BPS. A second gastroenterologist administered the drugs and monitorized the patient. Results. All the 112 patients (62 males, mean age 58.35) completed the examination. The mean dose of midazolam and propofol was, respectively, of 2.1?mg (range 1–4?mg) and 350?mg (range 180–400). All patients received oxygen with a mean flux of 4 liter/minute (range 2–6 liters/minute). The mean recovery time after procedure was 25 minutes (range 18–45 minutes). No major complications related to sedation were registered during all procedures. The oxygen saturation of all patients never reduced to less than 85%. Blood systolic pressure during and after the procedure never reduced to less than 100?mmHg. Conclusions. In our experience BPS administered by non-anaesthesiologists provided safe and successful sedation in patients undergoing EUS-FNA. 1. Background Propofol is a short-acting sedative, agonist of -aminobutyric acid receptor in the central nervous system [1]. Its use has principally been limited to anesthesiologists for the induction and maintenance of deep sedation in patients undergoing surgical procedures. Recently propofol use has extended to sedation in endoscopic procedure, administered by anesthesiologists or by gastroenterologists [2]. Propofol administered by nonanesthesiologists has shown to be safe for an upper endoscopy, a colonoscopy, and advanced endoscopic procedures, such as an ERCP and an EUS [3]. For endoscopic procedures the use of midazolam, with or without meperidine, in combination with propofol is called balanced propofol sedation (BPS). It has been shown that BPS compared to propofol alone decreases total propofol doses required and increases patient comfort [4–6]. 2. Aim of the Study The purpose of this preliminary study was to assess safety and feasibility of gastroenterologist-administered BPS for operative upper EUS in a tertiary referral center with a previously established program for colonoscopy sedation with propofol. 3. Patients and Methods The study received approval from our institutional review board. From February 2008 to December 2009 patients who presented at our unit for an operative EUS were
LA REPRESENTATION DU CORPS HYBRIDE DANS LE ROMAN DE PERCEFOREST
Andréa RANDO-MARTIN
Studii si Cercetari Filologice : Seria Limbi Romanice , 2012,
Abstract: Les arts rhétoriques antiques, qui servent de fondement à la tradition médiévale, affirment l’impossibilité de représenter les êtres hybrides, marqués par une contradiction essentielle et une profonde laideur. Pourtant l’examen des portraits consacrés par le Roman de Perceforest à trois figures d’hybrides permet de déterminer les conditions et les limites de cette représentation. Il s’agit ici d’observer la manière dont le roman médiéval négocie l’impasse de la rhétorique antique et donne, dans le texte, sens et existence au corps hybride.
Organization of the lithic production and use-wear analysis from Middle Paleolithic site of Abric Romaní. Level Ja (Capellades, Barcelona, Spain)
Martínez, Kenneth,Rando, José María
Trabajos de Prehistoria , 2001,
Abstract: The fieldwork from layer Ja at Abric Romaní provides some interesting insights on the examination of patterns of late premodern hominid behavior The reconstruction of chaine opératoire and use-wear analysis point out planning in the consumption of raw materials and in the design of stone tools for specific tasks. The archaeological record shows complexity in the settlement system and intrasite context, likewise, the land use depends mainly on the curation of tools through transport of cores, like reserve of tools, and retouched tools. The flakes were versatile tools; working wood, hide and participating in butchering activities and denticulates were used mainly on wood, probably to make points. So far, this work seeks to understand Middle Paleolithic way of life in its own right without comparing it with a hypothetical model of modern behavior. La intervención arqueológica del nivel Ja del Abric Romaní ha aportado una información muy valiosa para comprender los patrones conductuales de los últimos homínidos arcaicos. La reconstrucción de la organización de la producción lítica y los análisis funcionales indican una planificación a la hora de gestionar la materia prima y en el dise o de los útiles según tareas específicas. El registro arqueológico muestra una estructuración compleja de las ocupaciones en el interior del abrigo, así como una organización a escala regional de las ocupaciones. La explotación del entorno dependía principalmente de una gestión cuidada de la materia prima mediante el desplazamiento por el territorio de núcleos, como reserva de útiles, y de objetos retocados. Las lascas fueron útiles versátiles, trabajaron tanto madera como piel, y también participaron en actividades de carnicería. Por su parte, los denticulados fueron utilizados para trabajar madera, probablemente para elaborar puntas en este material. Por tanto, el presente artículo intenta comprender el modo de vida de las comunidades de neandertales sin compararlo con hipotéticos modelos conductuales de los homínidos modernos.

Abstract: endoscopic percutaneous gastrostomy is a safe technique although with potential complications before which the clinician has to be on alert in order to early detect them even after a long period of normal functioning. most of them represent minor problems. gastrocolocutaneous fistula is a rare but severe complication favored by some risk factors such as previous post-surgical adherences, deformities of the spine, or excessive gastric inflation at the time of performing the technique. we present the case of a patient with peg with this complication that occurred after the first tube replacement. our goal was in two senses: on the one hand, to analyze the preventive aspects and basic guidelines for a safe peg placement to minimize the risks; on the other hand, to alert on the possible presence of this entity to prevent a progressive nutritional impairment. this complication ought to be included in the differential diagnosis of the diarrhea syndrome in the patient carrying a peg. the diagnostic techniques of choice are radiologic tests such as ct scan and contrast media administration through the tube. surgical therapy should be reserved to patients with acute peritonitis in order to perform a new gastrostomy.

Abstract: The fatty acids composition and the related health lipid indices (IA, atherogenic and IT thrombogenic) of Blue Fin Tuna’s (Thunnus thynnus L.) raw roe and their cured product bottarga, both considered a delicacy, were studied. The fatty acid (FA) composition of tuna’s roe and bottarga showed a relevant proportion (40.87% and 36.62% respectively) of poly-unsaturated fatty acids (PUFAs) with a prevalence of the n – 3 series, that showed values almost ten folds higher than those of n – 6 fatty acids, in both classes of analyzed samples. The IA and IT indices resulted comparable in tuna’s roe and in the bottarga samples respectively. To the best of our knowledge, this is the first detailed report on the fatty acids composition and the related lipid health indices in tuna’s raw roe and in their cured product “bottarga”.
