    Full Text Available Encephalotrigeminal angiomatosis (Sturge-Weber syndrome is a rather uncommon congenital condition characterized by the combination of venous angioma of the leptomeninges over the cerebral cortex with ipsilateral angiomatous lesions of the face, and sometimes the skull, jaws, and oral soft tissues. A case of portwine stain with intraoral gingival hemangioma is presented. There were no other systemic manifestations. Patient reported with a complaint of localized tumor-like swelling in gums. Based on the presence of sharply demarcated vascular lesion unilaterally on the face and with ipsilateral intraoral vascular hyperplasia in the lip and gingiva, a variant of encephalotrigeminal angiomatosis was diagnosed. Ultrasound Doppler flowmetry was used to determine the blood flow. Dental management included plaque control instructions, scaling, root planning, and excision of the lesion done under general anesthesia. Close follow-up and meticulous plaque control have kept the oral condition under fairly good control.

    Facial port-wine stains are capillary malformations, which can reveal, very rarely, Sturge-Weber syndrome (SWS). SWS is a severe neurocutaneous syndrome, which involves a facial port-wine stain reaching the first branch of trigeminal nerve (V1), ophthalmologic abnormalities (especially congenital glaucoma) and neurologic signs (seizure, mental retardation, hemiparesis). Neuroimaging (CT-scan/angio-magnetic resonance imaging [MRI]) provides the diagnosis of SWS, when it shows ipsilateral leptomeningeal angioma; the best age to perform the exam is not established. Extension to superior eyelid, to other territories of trigeminal nerve (V2, V3) or to the contralateral hemiface is statistically associated to SWS. When a new-born has a facial port-wine stain reaching V1, ophthalmologic examination must be performed in the first months of life, as well as neuroimaging (at the age of 6-12 months, earlier in case of neurologic signs); a treatment of the port-wine stain by pulsed dye laser must also be considered.

    Full Text Available An account of Professor Karlo Weber's life is given. He was born January 25th, 1902 in Mramorak (Vojvodina and died September 1st, 1978 in Zagreb. He studied chemistry and physics in Graz and Freiburg and obtained his Ph. D. at the University of Graz in 1926. The first part of his career from 1927 to 1945 Weber spent at the Department of Chemical Technology, Technical Faculty. His advancement from assistantship to full-professorship was not smooth. After May 8th, 1945, Weber barely saved his life and on September 5th, 1945 was formally dismissed from the Technical Faculty. He was out of a job, but soon was employed in the bookstore Juraj Križanić first as a staff-member and then as a salesman. Weber was dismissed from this job on June 30th, 1946. Two weeks later, he joined the Department of Forensic Medicine, Faculty of Medicine in Zagreb. He again started at the bottom of the hierarchy as a low-paid lab-assistant, but being a very able researcher he advanced relatively quickly to the position of full research professor in 1960.Weber was a physical chemist whose main research interest were chemical kinetics, photochemistry and optical phenomena (luminescence, fluorescence, photography. The more important part of his research work was published while he was at the Department of Chemical Technology. In the Department of Forensic Medicine, Weber encountered research different kind of problems – problems from forensic medicine and toxicology. This change in research environment did not prevent Weber in his productivity, he published 159 research papers, more than 70 technical papers, and 4 monographs. Among them especially prominent is Inhibitorwirkungen – Eine Darstellung der Negative Katalyse in Lösungen (Ferdinand Enke-Verlag, Stuttgart, 1938., which was the first monograph on the subject.Under his supervision, 13 M.

    This essay compares and contrasts the means by which Durkheim and Weber dealt with methodological issues peculiar to the comparative study of societies, what Smelser has called "the problem of sociocultural variability and complexity." More specifically, it examines how Weber and Durkheim chose appropriate comparative units for their empirical studies. The approaches that Weber and Durkheim brought to theproblem of cross-cultural comparison have critical implications for more current procedures used in the comparative study of contemporary and historical societies.

  14. Max Weber entre liberalismo y republicanismo

    Directory of Open Access Journals (Sweden)

    Villacañas Berlanga, José Luis

    2005-12-01

    Full Text Available This article attempts to analyze the differences between social democracy and political democracy as modern processes, as these were understood by Max Weber. The archetype of modernity resides, from this point of view, in a convergence of both processes, as occurred in countries like the USA and Great Britain. Weber's diagnosis is that, whereas social democracy can be organized around liberal arguments, political democracy cannot advance without republican concepts like those of virtue, rigour, responsability and representation. For Weber, these values could only become present in Germany thanks to an adequate and democratic reception of Nietzsche, and in some way this reception could make sense of the former's work.

    Este artículo pretende analizar las diferencias entre democracia social y democracia política como procesos modernos, tal y como fueron comprendidos por Max Weber. Lo arquetípico de la modernidad reside, desde este punto de vista, en una convergencia de ambos procesos, tal y como se dio en países como USA y Gran Bretaña. El diagnóstico de Weber es que, mientras la democracia social puede organizarse sobre argumentos liberales, la democracia política no puede avanzar sin conceptos republicanos como el de virtud, rigor, responsabilidad y representación. Para Weber, estos valores sólo podrían hacerse presentes en Alemania a partir de una recepción adecuada y democrática de Nietzsche y en cierto modo esta recepción daría sentido a su obra.

    2010-01-01

    Full Text Available Établir la distinction entre le vieux et le neuf et montrer comment on passe de l'un à l'autre sont des enjeux primordiaux dans la sociologie de la religion de Max Weber. Dans cet article, on montre comment Weber les a traités ainsi que ses difficultés à les affronter. Pour Weber, la transition du vieux vers le neuf exige une certaine "transformation de l'âme humaine", ou bien une rupture tranchée avec les types de mentalités tenues pour traditionnelles. On propose que cette conception l'a mené à considérer des ruptures inexistantes (par exemple entre les esprits luthériens et calvinistes et à ne pas s'apercevoir de ruptures importantes (par exemple, entre la tolérance particulière à nos jours et celle d'époques précédentes. On conclut qu'il y a une analogie entre la sociologie webérienne de la religion et la physique aristotélicienne et que, à la lumière de cette analogie, on peut mieux comprendre ce que Weber veut signifier lorsqu'il affirme que des transitions historiquement significatives demandent une "transformation de l'âme humaine".

  17. Rat Model of Parkes Weber Syndrome.

    Directory of Open Access Journals (Sweden)

    Krzysztof Bojakowski

    Full Text Available The Parkes Weber syndrome is a congenital vascular malformation, characterized by varicose veins, arterio-venous fistulas and overgrown limbs. No broadly accepted animal model of Parkes Weber syndrome has been described. We created side-to-side arterio-venous fistula between common femoral vessels with proximal non-absorbable ligature on common femoral vein limiting the enlargement of the vein diameter in Wistar rats. Contralateral limb was sham operated. Invasive blood pressure measurements in both iliac and inferior cava veins were performed in rats 30 days after fistula creation. Tight circumference and femoral bone length were measured. Histopathology and morphology of soleus muscle, extensor digitorum longus muscle, and the common femoral vessel were analyzed. 30 days following arterio-venous fistula creation, a statistically significant elevation of blood pressure in common iliac vein and limb overgrowth was observed. Limb enlargement was caused by muscle overgrowth, varicose veins formation and bone elongation. Arterio-venous fistula with proximal outflow limitation led to significant increase of femoral vein circumference and venous wall thickness. Our study indicates that the described rat model mimics major clinical features characteristic for the human Parkes Weber syndrome: presence of arterio-venous fistula, venous hypertension and dilatation, varicose veins formation, and the limb hypertrophy. We reveal that limb overgrowth is caused by bone elongation, muscle hypertrophy, and venous dilatation. The newly established model will permit detailed studies on the mechanisms underlying the disease and on the efficacy of novel therapeutic strategies for the Parkes Weber syndrome treatment.

    2006-01-01

    This paper investigates various Weber problems including unconstrained Weber problems and constrained Weber problems under l1,l2 and l∞-norms. First with a transformation technique various Weber problems are turned into a class of monotone linear variational inequalities. By exploiting the favorable structure of these variational inequalities, we present a new projection-type method for them. Compared with some other projection-type methods which can solve monotone linear variational inequality, this new projection-type method is simple in numerical implementations and more efficient for solving this class of problems; Compared with some popular methods for solving unconstrained Weber problem and constrained Weber problem, a singularity would not happen in this new method and it is more reliable by using this new method to solve various Weber problems.

    Sturge-Weber syndrome is a sporadic congenital neurocutaneous disorder caused by a somatic activating mutation in GNAQ; it affects 1 in every 20,000 to 50,000 newborns. It is characterized by a facial Port-wine stain, leptomeningeal angiomatosis, and glaucoma. Seizures are the most common neurological manifestation and typically present in the first months of life. Glaucoma may be present at birth or develop later. Neuroimaging studies show leptomeningeal angiomatosis, supporting diagnosis. Standard treatment for Sturge-Weber syndrome includes laser treatment for the Port-wine stain, anticonvulsants, and medical or surgical treatment for the glaucoma. Prognosis depends on the extent of leptomeningeal involvement and the severity of the glaucoma. Copyright © 2016 AEDV. Publicado por Elsevier España, S.L.U. All rights reserved.

    Full Text Available Sturge-Weber syndrome (SWS, also known as encephalotrigeminal angiomatosis, a sporadic, non-familial, congenital disorder consists of congenital hamartomatous malformations that may affect the eye, skin and central nervous system at different times. Sturge-Weber syndrome is classified as 1 Complete trisymptomatic: - when all three organ systems i.e. eye, skin and CNS are involved 2 Incomplete bisymptomatic:- when the involvement is either oculocutaneous or neurocutaneous, and 3 Incomplete monosymptomatic: when there is only neural or cutaneous involvement. Failure of proper vascular development is believed to be the most likely cause of this condition. The malformed blood vessels or hemangiomas may lead to port-wine stain, epilepsy and glaucoma depending on its location. Three classic variants with typical findings are discussed.

    Palheta Neto, Francisco Xavier

    2008-12-01

    Full Text Available Introduction: The Syndrome of Sturge-Weber is a rare condition of congenital development, and is characterized by a neurocutaneous disorder with angiomas wrapping the leptomeninges and the face skin, mainly in the course of ophthalmic (V1 and maxillary (V2 branches of the trigeminal nerve. Objective: To review the literature about the Sturge-Weber Syndrome with emphasis on the current aspects. Method: The following databases were searched: EMedicine, Encyclopedia of Medicine, FindArticles, LILACS, MEDLINE, Merck Manuals On-Line Medical Library and Scielo, and the searches applied the terms: Sturge-Weber Syndrome, neurocutaneous syndromes, encephalo-trigeminal angiomatosis, nevus flammeus, in articles published between 1991 and 2007. Literature's Review: The most characteristic clinical statement is the presence, since the birth, of nevus flammeus, that generally reaches one half of the face and may stretch out up to the neck; in addition, other clinical manifestations may be present, like the corticocerebral angiomatosis, cerebral calcifications, epilepsy, ocular and buccal affections and mental retardation. The diagnosis is established by means of the inquiry of neurological and ophthalmic alterations in patients with a characteristic nevus flammeus, allied to the clinical data of complementary exams such as Computerized Tomography. The treatment consists basically of controlling the already confirmed clinical manifestations and preventing from the appearing of other alterations, mainly buccal and ocular. Conclusion: This syndrome is not much frequent, but it needs to be early diagnosed, since it brings a series of complications to its carriers when not treated, specially because of reaching the Nervous Central System. The health professionals have to be suitably able to recognize its characteristic signs and symptoms, and so improve the quality of life of these patients.

    Sturge-Weber syndrome (SWS) is a rare, sporadic, progressive, congenital syndrome. In its complete trisymptomatic form, SWS is physically characterized by port-wine stains over the trigeminal area, leptomeningeal angiomas usually over the parieto-occipital region, and eye abnormalities. Clinical manifestation for infants with SWS depends on the affected organs, but can include seizures, mental retardation, and glaucoma. This article begins with a case presentation of an infant with SWS and then presents the etiology, embryology, pathophysiology, clinical presentation, management, and prognosis of SWS.

    2009-09-01

    By using the techniques developed for generating high-speed droplets, we have systematically investigated binary droplet collision when the Weber number (We) was increased from the range usually tested in previous studies on the order of 10 to a much larger value of about 5100 for water (a droplet at 23 m/s with a diameter of 0.7 mm). Various liquids were also used to explore the effects of viscosity and surface tension. Specifically, beyond the well-known regimes at moderate We's, which exhibited coalescence, separation, and separation followed by satellite droplets, we found different behaviors showing a fingering lamella, separation after fingering, breakup of outer fingers, and prompt splattering into multiple secondary droplets as We was increased. The critical Weber numbers that mark the boundaries between these impact regimes are identified. The specific impact behaviors, such as fingering and prompt splattering or splashing, share essential similarity with those also observed in droplet-surface impacts, whereas substantial variations in the transition boundaries may result from the disparity of the boundary conditions at impacts. To compare the outcomes of both types of collisions, a simple model based on energy conservation was carried out to predict the maximum diameter of an expanding liquid disk for a binary droplet collision. The results oppose the dominance of viscous drag, as proposed by previous studies, as the main deceleration force to effect a Rayleigh-Taylor instability and ensuing periphery fingers, which may further lead to the formations of satellite droplets.

    Full Text Available Sturge-Weber syndrome (SWS is a sporadic disorder and is frequent among the neurocutaneous syndromes specifically with vascular predominance. This syndrome consists of constellation of clinical features like facial nevus, seizures, hemiparesis, intracranial calcifications, and mental retardation. It is characterized by focal port-wine stain, ocular abnormalities (glaucoma, and choroidal hemangioma and leptomeningeal angioma most often involving occipital and parietal lobes. The present paper reports three cases of SWS with oral manifestations and periodontal management, which included thorough scaling and root planing followed by gingivectomy with scalpel and laser in cases 1 and 3 consecutively to treat the gingival enlargement. However, the treatment in case 2 was deferred as the patient was not a candidate for periodontal surgery.

    2016-01-01

    We investigate the coherent and incoherent nonparaxial Weber beams, theoretically and numerically. We show that the superposition of coherent self-accelerating Weber beams with transverse displacement cannot display the nonparaxial accelerating Talbot effect. The reason is that their lobes do not accelerate in unison, which is a requirement for the appearance of the effect. While for the incoherent Weber beams, they naturally cannot display the accelerating Talbot effect but can display the nonparaxial accelerating properties, although the transverse coherence length is smaller than the beam width, based on the second-order coherence theory. Our research method directly applies to the nonparaxial Mathieu beams as well, and one will obtain similar conclusions as for the Weber beams, although this is not discussed in the paper. Our investigation identifies families of nonparaxial accelerating beams that do not exhibit the accelerating Talbot effect, and in addition broadens the understanding of coherence proper...

    Full Text Available Max Weber’s essay on The City, published after his death, has often been interpreted as a contribution to urban sociology or as a plea for ‘communal liberty’. The present article comes back to the reception of the text, examines it on the background of the research on urban problems at the time of Weber and insists on the strong relation of The City with the detailed analysis of the oriental city in The Economic Ethics of World Religions. Analysing these different contexts and Weber’s argumentation which is focalized on the Stadtwirtschaftspolitik as Verbandshandeln (urban economic policy as activity of a corporate group enables to clarify the nature and the purpose of Weber’s unfinished essay. It extends the questioning of The Protestant Ethic and the Spirit of Capitalism, investigating into the rationalization of economic life conducts and institutions in a certain type of medieval towns whose structural conditions had favoured the emergence of the rational capitalism of enterprise and of the modern state.

O fato de que a MWG reconstrói, de maneira bastante detalhada, o contexto histórico científico e intelectual torna mais evidente como os diferentes tópicos sobre os quais Weber trabalhou - a economia de mercado capitalista, as religiões do mundo ou o Estado moderno - foram abordados em última instância "do ponto de vista da história cultural". Diante desse quadro, meu artigo explora quatro aspectos principais: história econômica; ou mais precisamente o sentido cultural da ação econômica como ponto-chave para o pensamento histórico de Weber como um todo (I; a insistência de Weber na primazia de problemas analíticos e da escolha de perspectivas como pressupostos intelectuais do conhecimento histórico (II; a questão fundamental da história cultural em geral: como as ideias se atualizam em conflitos e constelações históricos e como a singularidade do desenvolvimento cultural europeu deve ser descrita em sua significação histórico-universal (III; a relevância da Primeira Guerra Mundial para os problemas e perspectivas de Weber: seu foco em uma teoria histórico-política do poder e da dominação e da gênese e estrutura do Estado moderno e da democracia (IV.This article takes a new look at Weber as a historian.

    2010-06-01

    Full Text Available This paper aims at providing a discussion on bureaucracy and education based on the comprehensive sociology developed by Weber. The choice of Max Weber seems to be the most appropriate due the diversity and depth of his intellectual production, what includes the issue of bureaucracy. The use of Weber should serve as a precise instrument of conceptual analysis on the theme addressed here. Certainly, this thinker has been one of the main scholars on bureaucracy, with focus on Germany at the time of the First World War (1914-1918. It is within such a productive theoretical framework that we intend to provide a few reflections about education and bureaucracy from a Weberian epistemological base.

    Sturge-Weber syndrome (SWS) is a rare congenital neurocutaneous disorder. It is characterized by the presence of facial port wine stains, neurological abnormalities like seizures and mental retardation, ocular disorders, oral involvement and leptomeningeal angiomas. A 13-year-old boy presented with the chief complaint of swollen, bleeding gums and deposits on the teeth. Detailed medical and dental history, clinical examination and investigations confirmed the diagnosis of Sturge-Weber syndrome. The treatment comprised of a thorough plaque control regimen to reduce the gingival enlargement, and it included oral hygiene instructions, thorough scaling, root planing at regular intervals and plaque index scoring which motivated the patient at each visit. This case illustrates that early intervention in a patient with Sturge-Weber syndrome is quintessential because of its associated gingival vascular features and their complicating manifestations. Furthermore, the need for periodic oral examinations and maintenance of good oral hygiene to prevent any complications from the oral vascular lesions has been highlighted.

  16. Weber and Kafka: The rational and the enigmatic bureaucracy

    DEFF Research Database (Denmark)

    Beck Jørgensen, Torben

    2012-01-01

    Max Weber’s and Franz Kafka’s respective understandings of bureaucracy are as different as night and day. Yet, Kafka’s novel The Castle is best read with Max Weber at hand. In fact, Kafka relates systematically to all the dimensions in Weber’s ideal type of bureaucracy and give us a much......’s painting: Ascending and Descending. Nevertheless, Weber and Kafka can both be right. While Kafka looks at the bureaucratic phenomenon through persons who are marginalized, Weber’s perspective is historic-comparative and top-down.

  17. Weber's planetary model of the atom

    Known is Wilhelm Weber together with Gaussfor the creation of the absolute measurement systems, foundation for the contemporary Si units. Here Weber's atomic model, originated around 1860, is presented.With the triumph of the field physics and the short-range interaction theory (Faraday, Maxwell, Heinrich Hertz) all to fastly the older electrodynamics was put as superseeded long-range interaction theory ad acta. Just at the end of the 19th century the idea of a substantial, atomistic structure of electricity (H. A. Lorentz, J. J. Thomson) had is way. On the base of Ampere's hypothesis of the molecular currents in Weber's atomic model electrical particles with electric charge and very small mass circulate around a ponderable atom or molecule, which carries also electrical charge. These circulating particles excite according to Weber in the ether light waves of constant frequency. The similarity with Bohr's atomic model - apart from the quantum conditions and quantum jumps - is amazing. Energetic consideration in the emission of the light waves Weber indeed not yet made. In the foundation of metal electronics Weber also started from Ampere's molecular currents. If voltage is put on the conductor ballistic motions of electrical particles result, which arrive so from the effective sphere of a ponderable atom in the effective sphere of a neighbouring atom. Based on these ideas then Riecke, Drude, and H. A. Lorentz created then the classical electron theory of the metals. Sommerfeld took up again the idea under usage of the quantum theory come into use, and solid-state physics began.

  18. Max Weber in the American Journal of Sociology: A case of circulating knowledge.

    By the middle of the 1970s, a Max Weber revival commenced in American sociology. Almost 75 percent of the articles on Weber in the American Journal of Sociology published in the past six decades appeared in the 1970s and 1980s. The Weber revival in American sociology is a phenomenon observed in leading literature. New translations and publications are frequently indicated reasons for the renewed interest in Weber. Without dismissing this factor, it is not an entirely satisfactory explanation. This article accounts for the Weber revival in a new way. Taking the American Journal of Sociology as a case study, I argue that the Weber revival was a case of circulating knowledge. Certain historically set issues led to a reorientation of Weber, which meant that knowledge about Weber was moved, extended, and transformed. © 2012 Wiley Periodicals, Inc.

    Full Text Available Sturge-Weber syndrome, also known as encephalotrigeminal angiomatosis or meningofacial angiomatosis, is characterised in its classical form by a congenital, usually unilateral, ‘portwine stain’ (capillary naevus on the face, convulsions, typical intracranial calcification and some degree of mental retardation and hemiparesis. The clinical correlation of intractable seizures with the presence of bilateral intracranial disease has management and prognostic implications, thus making the presence of bilateral disease an important factor to all those involved in the management of the child with Sturge-Weber syndrome.

  2. Peritonsillar Abscess: Complication of Acute Tonsillitis or Weber's Glands Infection?

    2016-08-01

    To review the literature concerning the 2 primary hypotheses put forth to explain the pathogenesis of peritonsillar abscess: "the acute tonsillitis hypothesis" (peritonsillar abscess is a complication of acute tonsillitis) and "the Weber gland hypothesis" (peritonsillar abscess is an infection of Weber's glands). PubMed, EMBASE. Data supporting or negating one hypothesis or the other were elicited from the literature. Several findings support the acute tonsillitis hypothesis. First, the 2 main pathogens in peritonsillar abscess have been recovered from pus aspirates and bilateral tonsillar tissues with high concordance rates, suggesting that both tonsils are infected in patients with peritonsillar abscess. Second, studies report signs of acute tonsillitis in the days prior to and at the time of peritonsillar abscess. Third, antibiotic treatment reduces the risk of abscess development in patients with acute tonsillitis. However, some findings suggest involvement of the Weber's glands in peritonsillar abscess pathogenesis. First, high amylase levels have been found in peritonsillar pus. Second, the majority of peritonsillar abscesses are located at the superior tonsillar pole in proximity of the Weber's glands. We propose a unified hypothesis whereby bacteria initially infect the tonsillar mucosa and spread via the salivary duct system to the peritonsillar space, where an abscess is formed. Our findings support the rationale for antibiotic treatment of patients with severe acute tonsillitis to reduce the risk of abscess development. Improved understanding of peritonsillar abscess pathogenesis is important for the development of efficient prevention strategies. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

    2013-09-01

    The present study explores and compares Jaspers' methodology of psychopathology with Weber's methodology of sociology. In his works, Weber incorporated the arguments of many other researchers into his own methodology. Jaspers respected Weber as a mentor and presented arguments that were very similar to Weber's. Both Weber and Jaspers began from empathic understanding, but at the same time aimed for a rational and ideal-typical conceptualization. In addition, their methodologies were similar with respect to their detailed terminology. Such similarities cannot be seen with any other scholars. This suggests that Weber may have played an integral role as a mediator between his contemporary scholars and Jaspers. Thus, Weber may have had the most significant influence on Jaspers.

    Psychiatry can be seen as a natural and cultural science. According to this the postulate of freedom is its strong value judgment. Since the times of enlightenment it has been described metaphorically by the myth of the expulsion from Paradise. Following Max Weber and Wilhelm Dilthey, Karl Jaspers has introduced this perspective into psychiatry. His strict dichotomy between explaining and understanding has later been critically revised by Werner Janzarik and Hans Heimann. Their concepts of structure dynamic, of pathography and of anthropology are closer to Max Weber who connected natural and cultural sciences in a much stronger way. Especially the pathographic example of Nietzsche allows to demonstrate the differences between Jaspers and the later psychopathologists of the Heidelberg and Tübingen schools.

    Recently, Holmes et al. (2011b) suggested that grasping is only subject to Weber's Law at early but not late points of a grasping movement. They therefore conclude that distinct visual computations and information may guide early and late portions of grasping. Here, we argue that their results can be explained by an interesting statistical artifact, and cannot be considered indicative of the presence or absence of Weber's Law during early portions of grasping. Our argument has implications for other studies using similar methodology (e.g., Heath et al., 2011, Holmes et al., 2011a, 2012), and also for the analysis of temporal data (often called time series) in general.

  13. Diffusivity anomaly in modified Stillinger-Weber liquids

    2014-01-01

    By modifying the tetrahedrality (the strength of the three body interactions) in the well-known Stillinger-Weber model for silicon, we study the diffusivity of a series of model liquids as a function of tetrahedrality and temperature at fixed pressure. Previous work has shown that at constant temperature, the diffusivity exhibits a maximum as a function of tetrahedrality, which we refer to as the diffusivity anomaly, in analogy with the well-known anomaly in water upon variation of pressure at constant temperature. We explore to what extent the structural and thermodynamic changes accompanying changes in the interaction potential can help rationalize the diffusivity anomaly, by employing the Rosenfeld relation between diffusivity and the excess entropy (over the ideal gas reference value), and the pair correlation entropy, which provides an approximation to the excess entropy in terms of the pair correlation function. We find that in the modified Stillinger-Weber liquids, the Rosenfeld relation works well above the melting temperatures but exhibits deviations below, with the deviations becoming smaller for smaller tetrahedrality. Further we find that both the excess entropy and the pair correlation entropy at constant temperature go through maxima as a function of the tetrahedrality, thus demonstrating the close relationship between structural, thermodynamic, and dynamical anomalies in the modified Stillinger-Weber liquids.

    2017-06-01

    Sturge-Weber syndrome results in leptomeningeal vascular malformations, medically refractory epilepsy, stroke(s), and cognitive impairments. Cannabidiol, a cannabinoid without psychoactive properties, has been demonstrated in preclinical models to possibly have anticonvulsant, antioxidant, and neuroprotective actions. Five subjects with Sturge-Weber syndrome brain involvement and treatment-resistant epilepsy were enrolled. Motor seizure frequency, quality of life, and adverse events were recorded from the eighth week of the pretreatment period, eight weeks after starting maintenance dose (week 14), and the most recent visit. Four subjects had data through week 14, one of whom initially withdrew for lack of efficacy but because of other benefits re-enrolled with a lower dose. Two subjects at week 14 and three subjects with bilateral brain involvement had at the last visit a greater than 50% seizure reduction, reported an improved quality of life, and remained on cannabidiol 63-80 weeks after starting the drug. Three subjects reported mild side effects considered related to cannabidiol. This study suggests that cannabidiol may be well tolerated as adjunctive medication for seizure management and provides initial data supporting further study of cannabidiol in individuals with Sturge-Weber syndrome.

    Full Text Available Iris recognition is a robust biometric technology. This paper proposes a novel local descriptor for bovine iris recognition, named Gabor Weber local descriptor (GWLD. We first compute the Gabor magnitude maps for the input bovine iris image, and then calculate the differential excitation and orientation for each pixel over each Gabor magnitude map. After that, we use these differential excitations and orientations to construct the GWLD histogram representation. Finally, histogram intersection is adopted to measure the similarity between different GWLD histograms. The experimental results on the SEU bovine iris database verify the representation power of our proposed local descriptor.

    It was recently demonstrated that Stillinger-Weber silicon undergoes a liquid-liquid first-order phase transition deep into the supercooled region (Sastry and Angell 2003 Nat. Mater. 2 739). Here we study the effects of perturbations on this phase transition. We show that the order of the liquid-liquid transition changes with negative pressure. We also find that the liquid-liquid transition disappears when the three-body term of the potential is strengthened by as little as 5%. This implies that the details of the potential could affect strongly the nature and even the existence of the liquid-liquid phase.

    Sturge-Weber syndrome (SWS) is a neurocutaneous syndrome characterized by a facial nevus flammeus associated with seizures, developmental delay, and, often, with hemiparesis and hemianopia. On MRI, the most characteristic finding has been reported to be leptomeningeal enhancement, believed to represent leakage of contrast medium through the anomalous pial vessels that characterize the disease. We present a case of SWS with no evidence of leptomeningeal enhancement. This case illustrates that leptomeningeal enhancement need not be present in SWS, and the absence of this characteristic finding does not preclude the diagnosis. (orig.) With 2 figs.

    Hereditary hemorrhagic teleangiectasia (HHT or Rendu-Osler-Weber Syndrome) is an inherited autosomal dominant disorder of the vascular connective tissue. The resulting vascular malformations can occur in virtually any organ. Nosebleeds can massively impact on the quality of life of those afflicted. However, visceral manifestations are likely to be more serious, and may be comparable with a "ticking time bomb". Most commonly affected are the vascular systems of the lungs, liver, brain and gastrointestinal tract. Screening is recommended--at least with regard to the lungs. Difficult constellations of this complex condition may be successfully managed by an interdisciplinary approach.

  13. Carisma e Racionalismo na Sociologia de Max Weber

    Directory of Open Access Journals (Sweden)

    2011-06-01

    Full Text Available O artigo aborda o conceito de carisma de Max Weber, tomando como hipótese a relação entre a categoria do carisma e um problema de explicação, que pode ser sintetizado na pergunta: como surge o novo na história e como o mundo se transforma e toma uma nova direção? O carisma não é apenas um tipo (de dominação irracional e revolucionário; porém, principalmente, um modelo sociológico explicativo para a compreensão da mudança social. Neste sentido, Weber elabora o conceito do carisma como uma categoria complementar ao conceito de racionalismo. A história da sociedade se movimenta no campo das tensões entre o irracionalismo e o irracionalismo. O carisma pode ser vis¬to como uma chave sociológica para o entendimento dos processos sociais nos quais as aparentes tendências evolucionistas e unidimensionais do racionalismo se rompem de modo explosivo, suspendendo as instituições para ganhar o domínio e controle através de formas pessoalizadas em contextos coletivos. O processo de cotidianização do carisma, entretanto, acaba sempre em nova racionalização das esferas da vida.

    Full Text Available Sturge-Weber-Krabe syndrome (SWS, also known as encephalotrigeminalangiomatosis and named the forthfacomatosis, recall the names of the authors who first describedit in its basic clinical, radiological andanatomopathological aspects. We report here 14 cases of Sturge-Weber disease. In 6 of these, despite what had been previously described in literature, an extension of the angioma has been noted in other parts of the body. The study of these subjects stresses not only the need for a pharmacological/neuropsychomotor intervention, but alsothe need of a psychotherapeutic approach, for the emotional and affective implications thatcould derive from this syndrome. The reported cases are similar to those presented in literature for their main features. In particular, two elements are interesting: i the exceptional diffusion of the red nevousto the whole hemicorpo; and ii the evaluation of the way the patients live the disease, which has not beenpreviously considered in literature. We can conclude that SWS is a multisystem disorder that requires the neurologist to be aware of the possible endocrine, psychiatric, ophthalmological, and other medical issues that can arise and impact on the neurological status of the patients.

    The present authors encountered a rare traumatic case of Weber's syndrome in which computerized tomography (CT) revealed a hematoma localized in the tegmentum of the midbrain. This 49-year-old male was admitted because of a disturbed consciousness level caused by a hit on the right frontal area in a traffic accident. A neurological examination on admission disclosed Weber's syndrome: a dilatation of the right pupil, no reaction to direct or indirect light stimuli, ptosis of the right eyelid, lateral deviation of the right eyeball, and left hemiparesis with increased deep tendon reflexes and Babinski's sign. CT revealed a high-density area localized in the tegmentum of the midbrain, but interpeduncular and quadrigeminal cisterns were patent. After admission, his motor function and level of consciousness have showed improvement with medical treatment, but his right oculomotor palsy is unchanged. CT performed 7 days after admission showed a low-density area in place of the absorbed hematoma. In this case, the mechanism of the primary brain-stem injury could not be explained. However, there are four possible mechanisms: nerve avulsion, neurovascular friction, localized contusion, and shear strain injury. Careful consideration of the anatomical relationship shows that it is likely that the lesion was a contusional hemorrhage caused by impact on the tentorial edge.

  16. Log-Gabor Weber descriptor for face recognition

    The Log-Gabor transform, which is suitable for analyzing gradually changing data such as in iris and face images, has been widely used in image processing, pattern recognition, and computer vision. In most cases, only the magnitude or phase information of the Log-Gabor transform is considered. However, the complementary effect taken by combining magnitude and phase information simultaneously for an image-feature extraction problem has not been systematically explored in the existing works. We propose a local image descriptor for face recognition, called Log-Gabor Weber descriptor (LGWD). The novelty of our LGWD is twofold: (1) to fully utilize the information from the magnitude or phase feature of multiscale and orientation Log-Gabor transform, we apply the Weber local binary pattern operator to each transform response. (2) The encoded Log-Gabor magnitude and phase information are fused at the feature level by utilizing kernel canonical correlation analysis strategy, considering that feature level information fusion is effective when the modalities are correlated. Experimental results on the AR, Extended Yale B, and UMIST face databases, compared with those available from recent experiments reported in the literature, show that our descriptor yields a better performance than state-of-the art methods.

    In this paper, we present an extension of the Ghirardi-Rimini-Weber model for the spontaneous collapse of the wave function. Through the inclusion of dissipation, we avoid the divergence of the energy on the long-time scale, which affects the original model. In particular, we define jump operators, which depend on the momentum of the system and lead to an exponential relaxation of the energy to a finite value. The finite asymptotic energy is naturally associated to a collapse noise with a finite temperature, which is a basic realistic feature of our extended model. Remarkably, even in the presence of a low-temperature noise, the collapse model is effective. The action of the jump operators still localizes the wave function and the relevance of the localization increases with the size of the system, according to the so-called amplification mechanism, which guarantees a unified description of the evolution of microscopic and macroscopic systems. We study in detail the features of our model, at the level of both the trajectories in the Hilbert space and the master equation for the average state of the system. In addition, we show that the dissipative Ghirardi-Rimini-Weber model, as well as the original one, can be fully characterized in a compact way by means of a proper stochastic differential equation.

    Agave plants utilize crassulacean acid metabolism (CAM) for CO(2) fixation. Fructans are the principal photosynthetic products generated by agave plants. These carbohydrates are fructose-bound polymers frequently with a single glucose moiety. Agave tequilana Weber var. azul is an economically important CAM species not only because it is the sole plant allowed for tequila production but because it is a potential source of prebiotics. Because of the large amounts of carbohydrates in A. tequilana, in this study the molecular structures of its fructans were determined by fructan derivatization for linkage analysis coupled with gas chromatography-mass spectrometry (GC-MS), nuclear magnetic resonance (NMR), and matrix-assisted laser desorption time-of-flight mass spectrometry (MALDI-TOF-MS). Fructans were extracted from 8-year-old A. tequilana plants. The linkage types present in fructans from A. tequilana were determined by permethylation followed by reductive cleavage, acetylation, and finally GC-MS analysis. Analysis of the degree of polymerization (DP) estimated by (1)H NMR integration and (13)C NMR and confirmed by MALDI-TOF-MS showed a wide DP ranging from 3 to 29 units. All of the analyses performed demonstrated that fructans from A. tequilana consist of a complex mixture of fructooligosaccharides containing principally beta(2 --> 1) linkages, but also beta(2 --> 6) and branch moieties were observed. Finally, it can be stated that fructans from A. tequilana Weber var. azul are not an inulin type as previously thought.

    The purpose of this study was to evaluate ultrasound, MRI, and CT investigations in children with Sturge-Weber syndrome. From 1996 to 2005, a total of 15 investigations of the brain performed in 6 children with Sturge-Weber syndrome were reviewed. We evaluated four ultrasound, five CT, and six MRI exams. With ultrasound an increase of the echogenicity of the periventricular white matter was depicted in the first days of life. MRI is the best modality to demonstrate the vascular malformation, the impaired cerebral venous drainage, and the atrophy of one hemisphere. One-sided periventricular hyperechogenicity on ultrasound can be an early sign of Sturge-Weber syndrome in children with a nevus flammeus. MRI is the method of choice to diagnose Sturge-Weber syndrome and to follow up these children if the neurological status of the patients changes. (orig.)

    Full Text Available Sturge-Weber syndrome (SWS is a rare, sporadically occurring neurocutaneous disorder with a frequency of approximately 1 per 50,000. The hallmark is an intracranial leptomeningeal vascular angioma in association with a port wine nevus, usually involving ophthalmic or maxillary distribution of trigeminal nerve. Other clinical findings associated with SWS are seizures, glaucoma, hemiparesis and mental retardation. The radiological hallmark is "Tram-line" or "Gyri-form" calcification. 25 to 56% of patients experience recurrent episodes of paroxysmal focal neurological deficits in form of transient hemiparesis, which may be due to vascular ischemia or postictal in origin. EEG helps to differentiate the exact etiology, as it is normal in former. Aspirin prophylaxis in those, due to ischemia decreases their recurrences and improves overall neurological prognosis. We report a 25-month-old child of SWS with recurrent episodes of transient hemiparesis and atypical midline location of facial vascular nevus.

    Full Text Available Sturge-Weber syndrome (SWS also called as encephalotrigeminal angiomatosis, is a sporadically occurring rare neuro-cutaneous syndrome, characterized by vascular malformation with capillary venous angiomas involving face, choroidal layer of eye globe and leptomeninges responsible for ophthamological as well as neurological signs and symptoms. Authors report an interesting case, a six year old girl, who presented with seizures, facial port wine stain and normal psychomotor development. CT scan showed left cerebral hemiatrophy, left frontal and parieto occipital calcification with cortical calcification in left high frontal convexity. Cranial MRI scan also confirmed finding of left cerebral hemiatrophy and also revealed presence of gyriform cortical calcification, prominent flow voids seen in left basal ganglia. Her seizure is well controlled with antiepileptic medication. The pertinent literature is reviewed and management of such cases is discussed briefly.

  4. Noniterative Solution of Some Fermat-Weber Location Problems

    Full Text Available The Fermat-Weber problem of optimally locating a service facility in the Euclidean continuous two-dimensional space is usually solved by the iterative process first suggested by Weiszfeld or by later versions thereof. The methods are usually rather efficient, but exceptional problems are described in the literature in which the iterative solution is exceedingly long. These problems are such that the solution either coincides with one of the demand points or nearly coincides with it. We describe a noniterative direct alternative, based on the insight that the gradient components of the individual demand points can be considered as pooling forces with respect to the solution point. It is demonstrated that symmetrical problems can thus be optimally solved with no iterations, in analogy to finding the equilibrium point in statics. These include a well-known ill-conditioned problem and its variants, which can now be easily solved to optimality using geometrical considerations.

  5. A Weber-like law for perceptual learning.

    What determines how much an organism can learn? One possibility is that the neural factors that limit sensory performance prior to learning, place an upper limit on the amount of learning that can take place. We tested this idea by comparing learning on a sensory task where performance is limited by cortical mechanisms, at two retinal eccentricities. Prior to learning, visual performance at the two eccentricities was either unmatched or equated in two different ways (through spatial scaling or visual crowding). The magnitude of learning was equivalent when initial levels of performance were matched regardless of how performance was equated. The magnitude of learning was a constant proportion of initial performance. This Weber-like law for perceptual learning demonstrates that it should be possible to predict the degree of perceptual improvement and the final level of performance that can be achieved via sensory training, regardless of what cortical constraint limits performance.

    Full Text Available Abstract Background Agave tequilana Weber var. azul, is the only one variety permitted by federal law in México to be used for tequila production which is the most popular contemporary alcoholic beverage made from agave and recognized worldwide. Despite the economic, genetic, and ornamental value of the plant, it has not been subjected to detailed cytogenetic research, which could lead to a better understanding of its reproduction for future genetic improvement. The objective of this work was to study the meiotic behavior in pollen mother cells and its implications on the pollen viability in Agave tequilana Weber var. azul. Results The analysis of Pollen Mother Cells in anaphase I (A-I showed 82.56% of cells with a normal anaphase and, 17.44% with an irregular anaphase. In which 5.28% corresponded to cells with side arm bridges (SAB; 3.68% cells with one bridge and one fragment; 2.58% of irregular anaphase showed cells with one or two lagging chromosomes and 2.95% showed one acentric fragment; cells with two bridges and cells with two bridges and one acentric fragment were observed in frequencies of 1.60% and 1.35% respectively. In anaphase II some cells showed bridges and fragments too. Aberrant A-I cells had many shrunken or empty pollen grains (42.00% and 58.00 % viable pollen. Conclusion The observed meiotic irregularities suggest that structural chromosome aberrations have occurred, such as heterozygous inversions, sister chromatid exchanges, deletions and duplications which in turn are reflected in a low pollen viability.

  7. Weber's law, the magnitude effect and discrimination of sugar concentrations in nectar-feeding animals.

    Directory of Open Access Journals (Sweden)

    Vladislav Nachev

    Full Text Available Weber's law quantifies the perception of difference between stimuli. For instance, it can explain why we are less likely to detect the removal of three nuts from a bowl if the bowl is full than if it is nearly empty. This is an example of the magnitude effect - the phenomenon that the subjective perception of a linear difference between a pair of stimuli progressively diminishes when the average magnitude of the stimuli increases. Although discrimination performances of both human and animal subjects in various sensory modalities exhibit the magnitude effect, results sometimes systematically deviate from the quantitative predictions based on Weber's law. An attempt to reformulate the law to better fit data from acoustic discrimination tasks has been dubbed the "near-miss to Weber's law". Here, we tested the gustatory discrimination performance of nectar-feeding bats (Glossophaga soricina, in order to investigate whether the original version of Weber's law accurately predicts choice behavior in a two-alternative forced choice task. As expected, bats either preferred the sweeter of the two options or showed no preference. In 4 out of 6 bats the near-miss to Weber's law provided a better fit and Weber's law underestimated the magnitude effect. In order to test the generality of this observation in nectar-feeders, we reviewed previously published data on bats, hummingbirds, honeybees, and bumblebees. In all groups of animals the near-miss to Weber's law provided better fits than Weber's law. Furthermore, whereas the magnitude effect was stronger than predicted by Weber's law in vertebrates, it was weaker than predicted in insects. Thus nectar-feeding vertebrates and insects seem to differ in how their choice behavior changes as sugar concentration is increased. We discuss the ecological and evolutionary implications of the observed patterns of sugar concentration discrimination.

    Clinical presentation of a child with port-wine stain and seizures leads to the suspicion of Sturge-Weber disease (SWD). This diagnosis can be confirmed by the detection of a meningeal angiomatosis. In rare cases, early detection of meningeal pathology by ultrasound has been reported. Key findings are brain atrophy, gyriform cortical calcifications demonstrated by skull radiographs after the first year of life or earlier by cranial CT, and dys- or aplasia of the deep cerebral veins on angiography. Radionuclide imaging shows focal or diffuse tracer accumulation over the affected brain regions. MR demonstrates an abnormal appearance of the affected meninges, especially thickening and pathologically increased signal intensity after Gd-DTPA application. This, in association with the demonstration of abnormal enhancement in deep medullary veins, is the most characteristic finding. Contrast-enhanced MR allows early and non-invasive diagnosis of SWD, mainly by revealing leptomeningeal angiomatosis and abnormal venous vessels. (orig.).

    A 10-year-old girl presented with poorly controlled epilepsy. On evaluation, she had microcephaly, neuro-cutaneous stigmata of tuberous sclerosis complex, profound mental retardation, and spastic hemiparesis. Computed tomography (CT) revealed a calcified subependymal nodule and extensive left gyral calcification of the temporal, parietal, and occipital regions with unilateral cerebral atrophy, radiologic features usually seen in Sturge Weber syndrome. Magnetic resonance imaging (MRI) revealed absence of tubers, enlarged choroid plexus, or leptomeningeal angiomas, thus excluding type 3 Sturge Weber syndrome. The genotype was a heterozygous mutation in exon 18 of the tuberous sclerosis type 1 gene (c.2293C>T p.Q765X). A comparison of previously reported 7 cases of Sturge Weber syndrome and tuberous sclerosis complex was made. This revealed 4 actual double phakomatoses (clinical, radiologic, or genetic phenotypes) and 3 cases with clinical phenotype of tuberous sclerosis and gyral calcifications within tubers simulating the radiologic picture of Sturge Weber syndrome.

Tanto para Weber, como para Habermas, o conhecimento nas Ciências Sociais não consegue escapar das influências diretas da subjetividade do cientista, como também não é capaz de se proteger das contingências histórico-culturais aos quais inevitavelmente toda ação humana está vinculada. Por isso, fundamentados em suas próprias razões, tanto Weber quanto Habermas apontam a compreensão como a forma possível de conhecimento, o que implica a renúncia às pretensões explicativas e à produção de teorias gerais de fundamentação última, que são típicas das ciências convencionais.Assuming that the social theory developed by Habermas is very similar to that constructed by M.

    Although contemporary sociologists of science have sometimes claimed Max Weber as a methodological precursor, they have not examined Weber's own writings about science. Between 1908 and 1912 Weber published a series of critical studies of the extension of scientific authority into public life. The most notable of these concerned attempts to implement the experimental psychology or psycho-physics laboratory in factories and other real-world settings. Weber's critique centered on the problem of social measurement. He emphasized the discontinuities between the space of the laboratory and that of the factory, showing how several qualitative and historically conditioned differences between the two settings rendered the transfer of instruments and methods between them highly problematic. Weber's critical arguments prepared the ground for his greatest foray into empirical sociology, a survey he directed for the Verein für Sozialpolitik investigating the conditions and attitudes affecting the lives and performance of industrial workers. Using a different measuring instrument - the questionnaire - Weber tried to implement a concept of social measurement which implied a different ontology, drawn not from natural sciences but from the historical sciences.

  2. Occidental rationalism in Max Weber's sociology of music

    2009-01-01

    Full Text Available The paper views rationalism as a central category of an entire sociological endeavor of Max Weber in two dimensions: through the progress of mind in the understanding of 'the nature of things' and overcoming the resistance posed to the mind on that path by nature itself on the one hand, and through the struggle against irrationality of the very social beliefs and institutions which have gathered in history, on the other. When it comes to the first dimension, rationalization of music begins with the solving of the problem of the division of the octave (which cannot be divided symmetrically into equal parts and ends in the obstruction of the 'spiral' effect of intervals which the octave is composed of. (in order to ensure undisturbed successive or 'circular' lining of octaves. The other dimension is problematise in the relation with the ascetic ethics and the spirit of pentatonics, which is presented as similar to the relation between protestant ethics and the spirit of capitalism, only without the positive rationalist contributions of ascetic ethics.

    Full Text Available Ilse Weber (1903-1944 tuvo un papel de enorme envergadura en Theresienstadt. Su reputación como poeta y dramaturga del mundo infantil le facilitó, sin duda, una rápida integración en el amplio círculo de artistas e intelectuales checos que malvivían como podían en aquel “gueto especial”. Convertida en enfermera jefe de la comunidad judía del campo, durante los casi dos años que duró su residencia en el infierno utilizó la literatura como una herramienta terapéutica más orientada, casi obsesivamente, a ofrecer un poco de sentido a las vidas humilladas de quienes se hacinaban en la miserable enfermería que tenía a su cargo y, de un modo muy especial, a paliar con una guitarra en la mano, el profundo desconcierto emocional de los niños que aguardaban en Theresienstadt el turno de su muerte.

    The present study examined the intellectual and adaptive functioning in a sample of children and young adults with Sturge-Weber Syndrome. A total of 80 research participants from a SWS study database underwent full neurological evaluation as part of their participation or concurrent medical care. Twenty-nine of the participants received neuropsychological evaluations. Analyses indicated no significant demographic or neurological differences between those who did and did not receive neuropsychological evaluations. Overall, the neuropsychological evaluation sample displayed significantly lower functioning relative to published normative data across domains of intellectual and adaptive functioning. 32% of the sample displayed impaired performance (standard score ≤ 75) in intellectual functioning and 58% displayed impaired performance in adaptive functioning. Hemiparesis status independently predicted overall adaptive functioning while seizure frequency independently predicted overall intellectual functioning. Younger participants displayed significantly higher (more intact) ratings in adaptive functioning compared to older participants, specifically in overall adaptive functioning, motor skills, and community living skills. A composite measure of neurological status (SWS-NRS) incorporating seizure and hemiparesis status effectively distinguished between individuals with impaired or non-impaired adaptive and intellectual functioning, and showed promise as a screening method for identifying individuals with more involved intellectual and/or adaptive needs.

    Full Text Available Sturge-Weber syndrome (SWS, a rare sporadic neurocutaneous disease, is characterized by a congenital unilateral port-wine nevus affecting the area innervated by V1, ipsilateral leptomeningeal angiomatosis, and calcification in the occipital or frontoparietal region and glaucoma/vascular eye abnormality. Three types of SWS have been described in literature: Type I (classic demonstrates facial and leptomeningeal angioma, often with glaucoma; type II has facial angioma and glaucoma, with no evidence of intracranial lesions; and type III (rarest presents with only leptomeningeal angioma. Only a few cases of type III SWS have been reported. Here, we report a case of a seven-year-old boy with focal complex partial seizure, who was diagnosed with SWS without facial nevus. Recognition of this type of SWS is important, as our patient had been misdiagnosed and received inappropriate antiepileptic drugs for six years. We suggest that in the appropriate clinical scenario, the diagnosis of SWS without facial nevus should be considered before labelling idiopathic or cryptogenic localization-related epilepsy, and gadolinium-enhanced magnetic resonance imaging (MRI should be done in clinically suspicious cases of SWS, without facial nevus.

    Background: Although previous studies have reported soft-tissue management in surgical treatment of Sturge–Weber syndrome (SWS), there are few reports describing facial bone surgery in this patient group. The purpose of this study is to examine the validity of our multidisciplinary algorithm for correcting facial deformities associated with SWS. To the best of our knowledge, this is the first study on orthognathic surgery for SWS patients. Methods: A retrospective chart review included 2 SWS patients who completed the surgical treatment algorithm. Radiographic and clinical data were recorded, and a treatment algorithm was derived. Results: According to the Roach classification, the first patient was classified as type I presenting with both facial and leptomeningeal vascular anomalies without glaucoma and the second patient as type II presenting only with a hemifacial capillary malformation. Considering positive findings in seizure history and intracranial vascular anomalies in the first case, the anesthetic management was modified to omit hypotensive anesthesia because of the potential risk of intracranial pressure elevation. Primarily, both patients underwent 2-jaw orthognathic surgery and facial bone contouring including genioplasty, zygomatic reduction, buccal fat pad removal, and masseter reduction without major complications. In the second step, the volume and distribution of facial soft tissues were altered by surgical resection and reposition. Both patients were satisfied with the surgical result. Conclusions: Our multidisciplinary algorithm can systematically detect potential risk factors. Correction of the asymmetric face by successive bone and soft-tissue surgery enables the patients to reduce their psychosocial burden and increase their quality of life. PMID:27622111

  7. Optimizing Barrier Removal to Restore Connectivity in Utah's Weber Basin

    2016-12-01

    Instream barriers, such as dams, culverts and diversions are economically important for water supply, but negatively affect river ecosystems and disrupt hydrologic processes. Removal of uneconomical and aging in-stream barriers to improve habitat connectivity is increasingly used to restore river connectivity. Most past barrier removal projects focused on individual barriers using a score-and-rank technique, ignoring cumulative change from multiple, spatially-connected barrier removals. Similarly, most water supply models optimize either human water use or aquatic connectivity, failing to holistically represent human and environmental benefits. In this study, a dual objective optimization model identified in-stream barriers that impede aquatic habitat connectivity for trout, using streamflow, temperature, and channel gradient as indicators of aquatic habitat suitability. Water scarcity costs are minimized using agricultural and urban economic penalty functions to incorporate water supply benefits and a budget monetizes costs of removing small barriers like culverts and road crossings. The optimization model developed is applied to a case study in Utah's Weber basin to prioritize removal of the most environmentally harmful barriers, while maintaining human water uses. The dual objective solution basis was developed to quantify and graphically visualize tradeoffs between connected quality-weighted habitat for Bonneville cutthroat trout and economic water uses. Modeled results include a spectrum of barrier removal alternatives based on budget and quality-weighted reconnected habitat that can be communicated with local stakeholders. This research will help prioritize barrier removals and future restoration decisions. The modeling approach expands current barrier removal optimization methods by explicitly including economic and environmental water uses.

    Osler-Weber-Rendu disease, also known as hereditary hemorrhagic telangiectasia, is a rare autosomal dominant condition causing systemic fibrovascular dysplasia. It has an incidence of 1-2/100,000. Phenotypic variation is extreme ranging from asymptomatic to severely symptomatic, from cases with no or few mucocutaneous lesions to those with diffuse cutaneous telangiectasia. We discuss a case of Osler-Weber-Rendu disease causing diffuse cutaneous telangiectasia and hemoptysis. The patient presented with complaints of hemoptysis and was extensively examined and investigated before being diagnosed with Osler-Weber-Rendu disease. We successfully managed the patient's hemoptysis by bronchial artery embolization. This case emphasizes the need for careful examination and investigation and to consider such rare diseases when all the common causes of hemoptysis are ruled out. An early and proper diagnosis will lead to more effective management of such a rare disease with few treatment options available.

After a 7-day washout period, the groups were crossed. The primary outcome measure was postprandial ghrelin levels between minute 240 and minute 270. A. tequilana Weber inulin did not change postprandial ghrelin concentration in obese patients.

  12. The concept of adequate causation and Max Weber's comparative sociology of religion.

    Science.gov (United States)

    Buss, A

    1999-06-01

    Max Weber's The Protestant Ethic and the Spirit of Capitalism, studied in isolation, shows mainly an elective affinity or an adequacy on the level of meaning between the Protestant ethic and the 'spirit' of capitalism. Here it is suggested that Weber's subsequent essays on 'The Economic Ethics of World Religions' are the result of his opinion that adequacy on the level of meaning needs and can be verified by causal adequacy. After some introductory remarks, particularly on elective affinity, the paper tries to develop the concept of adequate causation and the related concept of objective possibility on the basis of the work of v. Kries on whom Weber heavily relied. In the second part, this concept is used to show how the study of the economic ethics of India, China, Rome and orthodox Russia can support the thesis that the 'spirit' of capitalism, although it may not have been caused by the Protestant ethic, was perhaps adequately caused by it.

Para Raymond Boudon, líder intelectual de la corriente de pensamiento sociológico inspirada en la teoría de la racionalidad de Weber, la lectura relativista de la obra de éste sería inaceptable. A pesar de las diferencias de posición teórica y desacuerdos entre ambos autores en torno a la obra de Weber podríamos bien retener como hipótesis de trabajo la idea de la irreductibilidad de Weber a una sola posición epistemológica, como lo propone Maffesoli. Es, pues, bajo este aspecto y en el marco de las diferencias de posición entre ambos autores que tratamos de considerar esta otra interpretación relativista que hace Maffesoli de la sociología comprensiva de Weber. Daremos cuenta de ello a través de una entrevista que el sociólogo francés nos ha amablemente acordado. Se trata, entonces, a de discernir los aspectos de la teoría sociológica de Weber que más marcan la obra de Maffesoli y b de acentuar al mismo tiempo las diferencias de posición existentes entre uno y otro, entre la lectura relativista que nos propone Maffesoli y la que predica Boudon en el marco del individualismo metodológico.

    2016-01-01

    The thesis that the theory of charismatic-plebiscitary democracy developed by Max Weber in the wake of the Weimar Republic was developed to its ultimate consequences by Carl Schmitt in the final crisis of Weimar has been hotly debated since it was first advanced in the 1950s. This paper proposes a fresh look at the controversy. By comparing both authors' concepts of politics in their relation to the problem of modernity, it argues that the Weber-Schmitt affair is neither a baseless legend nor a case of natural continuity. Instead, it should rather be understood in terms of a contingent affinity.

Von Kries had suggested a legal criterion for attributing a deed to an agent that exerted a strong influence on German civil law and was also taken up by the legal system of other countries. This earned him the title of an honorary doctor of the law faculty of the University of Erlangen in 1897.

    2014-05-01

    Full Text Available This essay explores the theme of the legitimacy of power in Weber from the standpoints of social science, historical investigation and political reflection. It investigates how Weber develops this theme in Kategorienaufsatz (1913, Soziologische Grundbegriffe (1920, Die Stadt (1911-14 and Politische Schriften (1917-19. Power, as a relationship of command/obedience, is founded on the representations of legitimacy of the individuals involved and on the Einverständnis (consent which is the condition of possibility of this relationship. It is back to the medieval city that Weber traces the genesis and interweaving of various forms of legitimation, which continue to exist as possibilities even within the modern State. The memory of medieval events re-emerges when Weber, after Germany’s defeat in the First World War and the threat of revolution that followed, tries to lay a foundation for the legitimacy of “leader democracy” by reintroducing the command/obedience relationship between leaders and masses.

    Full Text Available Partindo do pressuposto de que a teoria social elaborada por Habermas em muito se assemelha àquela construída por M. Weber, procedeu-se a um estudo comparativo com a intenção de identificar as formas pelas quais Weber e Habermas elaboraram o conceito de compreensão, ao mesmo tempo em que e o elegeram, cada um a seu modo, como instrumento metodológico adequado às dificuldades da produção de conhecimento científico nas Ciências Sociais. Tanto para Weber, como para Habermas, o conhecimento nas Ciências Sociais não consegue escapar das influências diretas da subjetividade do cientista, como também não é capaz de se proteger das contingências histórico-culturais aos quais inevitavelmente toda ação humana está vinculada. Por isso, fundamentados em suas próprias razões, tanto Weber quanto Habermas apontam a compreensão como a forma possível de conhecimento, o que implica a renúncia às pretensões explicativas e à produção de teorias gerais de fundamentação última, que são típicas das ciências convencionais.

  9. THE WEBER THESIS OF CALVINISM AND CAPITALISM--ITS VARIOUS VERSIONS AND THEIR "FATE" IN SOCIAL SCIENCE.

    Science.gov (United States)

    Zafirovski, Milan

    2016-01-01

    The paper identifies and examines various multiple renditions of the so-called Weber Thesis of an historical association and convergence between ascetic Protestantism, above all Calvinism, and the emergence and development of modern capitalism as an economic spirit and system. Specifically, it detects at least four different versions and formulations or interpretations, thus casting doubt in the common view of the Weber Thesis as a single and monolithic theory or hypothesis. The paper also considers the status of the multiple versions of the Weber Thesis in post-Weberian and contemporary sociology and related disciplines like economics and history. It concludes that the weaker, relaxed renditions of the Weber Thesis have attained a greater success and more endured in contemporary social science than have its stronger, stricter versions. © 2015 Wiley Periodicals, Inc.

    2007-06-01

    Full Text Available The purpose of this article is to identify and explain the ideas underlying the images that Max Weber uses to make up his concept of political vocation. When he intends to outline such notion in the last lines of his conference “Politk als Beruf ”, he does it by using a highly aesthetic and cryptic language. This article takes this peculiarity into account and it tries, as far as possible, to turn the metaphors into concepts with the practical purpose of helping the reader to unravel the message that Weber wanted to transmit to his interlocutors. If this essay reaches its objective, it will be at the cost of tarnishing the plasticity of the images used by the German sociologist to point out his ideological platform.

  11. Optimization study of fructans extraction from Agave tequilana Weber azul variety

    Jesús Aarón SALAZAR-LEYVA

    Full Text Available Abstract Agave tequilana Weber azul variety is a valuable source of fructans. In this study, a response surface methodology was employed to optimize the extraction yield of fructans from agave pines. A Box Behnken factorial design was applied to evaluate the effects of several conditions such as extraction temperature, water raw material ratio and extraction time on extraction yield. Under the optimum extraction conditions (extraction temperature of 79.1 °C, water raw material ratio of 5.13 mL/g, and extraction time of 1.48 h fructans extraction yield was 83.12%. The chromatographic profile of the agave crude extract presented four peaks, out of which fructans were the most preponderant (~87%. The obtained results suggest that the response surface methodology is adequate to optimize fructans extraction from Agave tequilana Weber azul variety.

    Leonel Barreto

    2013-01-01

    Full Text Available The Rendu-Osler-Weber disease is a genetic disease which may lead to severe hemorrhage and less frequently to severe organ dysfunction. We report the case of a 22-year-old patient with no personal medical history who was involved in a motorcycle accident and exhibited severe complications related to large arteriovenous pulmonary shunts during his ICU stay. The patient developed an unexplained severe hypoxemia which was attributed to several arteriovenous shunts of the pulmonary vasculature by a contrast study during a transesophageal echocardiographic examination. The course was subsequently complicated by a prolonged coma associated with hemiplegia which was attributed to a massive paradoxical fat embolism in the setting of an untreated femoral fracture. In addition to hemorrhagic complications which may lead to intractable shock, arteriovenous malformations associated with the Rendu-Osler-Weber disease may involve the pulmonary vasculature and result in unexpected complications, such as hypoxemia or severe cerebral fat embolism in high-risk patients.

    2011-02-01

    Full Text Available A partire da una rilettura di opere, come Die Protestantische Ethik und der Geist der Kapitalismus e Die Boersenequete, l'articolo mostra che – in linea con quanto Max Weber aveva descritto – l'assenza di regole generali condivise e di controlli pubblici mette in crisi le fondamenta del sistema finanziario. La privatizzazione neoliberista degli organi di controllo della finanza e la creazione di oscuri strumenti finanziari hanno contribuito alla regressione dell'organizzazione giuridica dello Stato, mettendo a serio rischio il principio di calcolabilità razionale che per secoli ha costituito il fondamento della teoria economica. In conclusione, Weber contribuisce a cogliere uno dei nodi fondamentali della crisi americana contemporanea: l'erosione dell’autorità indipendente posta a tutela dell’integrità del sistema.

    Sturge-Weber syndrome consists of facial capillary malformation (port-wine stain) and abnormal blood vessels in the brain or eye. Seizures, developmental delay and intracranial and airway angiomata are principal concerns. We report a 28-year-old primiparous woman at 41 weeks of gestation with Sturge-Weber syndrome who developed unilateral weakness, aphasia, blurred vision and confusion. Preeclampsia was excluded. Neuroimaging showed left sided cerebral oedema and a right parieto-occipital lesion, most likely an angioma. Caesarean section was planned to avoid the risk of angioma rupture during labour. General anesthesia was avoided due to the haemodynamic response to laryngoscopy and reports of seizure-related mortality. Despite the possibility of raised intracranial pressure and precipitation of cerebral herniation, a lumbar epidural block was administered but failed. A subarachnoid block was successfully performed and a healthy infant delivered. The choice of anaesthesia was strongly influenced by detailed radiological investigations and multidisciplinary participation.

    The modified Atkins diet (MAD) is a dietary treatment for epilepsy which does not restrict fluids or calories. This theoretically makes the MAD safer than the ketogenic diet for children with Sturge-Weber syndrome (SWS). Five children aged 4-18 years with SWS and at least monthly intractable seizures were started prospectively on the MAD for 6 months. All children had urinary ketosis and seizure improvement, including 3 with > 50% seizure reduction.

    2015-12-01

    Full Text Available According to Leo Strauss, Max Weber has been the most salient proponent of modern social science, that is to say, of a value-free social science. The second chapter of Strauss’ Natural Right and History consists of a critical overview of Max Weber’s perspective and, in particular, of his attempt to build the modern social science edifice upon the ground of the distinction between facts and values. The work here delivered consists of a comment or close reading of the chapter of Strauss on Weber. The aim of this reading is to show how the Weberian distinction between facts and values dilutes the most basic skills of the man of science, leading towards a nihilistic social philosophy, and towards an absurd social science. At the same time, Strauss’ reading examines the Weberian diagnosis of modern civilization, by means of an analysis of the sociological and political figures of the specialist, the philistine, and the extremist. After an account of Strauss’ critic of Weber, this article considers the Straussian proposal of a return to political philosophy in its classical sense.

    Thought Experiments in Historiographic Function: Max Weber on Eduard Meyer and the Question of Counterfactuality. Max Weber's remarks on his colleague Eduard Meyer regarding counterfactual reasoning in history reflects a significant shift during the Methodenstreit around 1900. The question of attributing historical change strictly to either individual causes or abstract general laws has been tackled in a new way: By counterfactual reasoning a historian should be able to detect the most significant (and therefore meaningful) cause, event, or action for a certain historical outcome. Following Fritz Ringer, this paper argues that given the predominating methods of the natural sciences, scholars of the humanities conducted historical research by counterfactual thought experiments. This way, Weber pried open contemporary narratives (e.g. historicism), and by employing a unique historical causal analysis he made way for refined concepts to offer a model of interpretation that gave hope for a more feasible, practice-oriented approach to historical research than the epistemological discussions had hitherto offered. © 2015 WILEY-VCH Verlag GmbH & Co.

    To observe MR findings of vascular abnormality in Sturge-Weber syndrome and to determine the value of MRI in diagnosis. Ten patients with Sturge-Weber syndrome (age:3 months-32 years) were evaluated by MR imaging; in six and four cases, respectively, the results were correlated with those of CT and angiography. We retrospectively analysed changes in the cortical vein and deep venous system, including the medullary and subependymal vein, as well as enlargement of the choroid plexus, leptomeningeal enhancement, and changes in diploic space. In all cases except one, in which non-contrast enhanced study had been per formed, varying degrees of leptomeningeal enhancement were seen. In nine cases the cortical vein became smaller;enlargement of the choroid plexus was seen in eight cases, change in the diploic space in seven (including three in which there was angiomatous involvement), and enlargement of the deep venous system in seven. In younger patients, collateral pathways were less developed and leptomeningeal angiomatous changes were more pronounced than in those who were older. MRI is a useful modality for the evaluationn of vascular changes in Sturge-Weber syndrome. These changes vary according to a patient's age and the duration of the disease.

    Sturge-Weber syndrome is a sporadic congenital neurocutaneous disorder often related to varying degrees of motor impairment. The phenomenon of prolonged ictal paresis is a rare seizure sign that can be due to lesions affecting the centro-parietal lobe. Focal inhibitory motor seizures can be difficult to differentiate from other clinical entities such as stroke, migraine or postictal paresis. We describe the case of a 40-year-old patient suffering from Sturge-Weber syndrome, admitted due to prolonged right-sided hemiparesis following a usual seizure. Repeated EEGs during the prolonged deficit showed only intermittent left fronto-parietal sharp waves. (99m)Tc HMPAO-brain SPECT performed seven days after the last seizure showed a vast area of parieto-occipital hyperperfusion in the left hemisphere. Aggressive antiepileptic therapy dramatically improved the clinical symptoms and scintigraphic images, which corroborated the diagnosis of ictal paresis. This case highlights the role of SPECT in the evaluation of Sturge-Weber syndrome, not only to investigate progressive neurological deterioration, but also exacerbation of seizures or prolonged neurological deficits. In fact, it may be possible to document ongoing epileptic activity using SPECT, despite a non-contributory EEG, which may be of help in adapting a therapeutic strategy.

The Weber effect, which constitutes a peak in adverse event (AE reporting of a drug at the end of second year after regulatory approval followed by a continuous decline thereafter, has been considered an important bias for a long time. The existence of this bias in AE reporting of oncology drugs remains an underevaluated area, prompting a targeted examination.Methods: The US Food and Drug Administration (USFDA Adverse Event Reporting System (FAERS was studied for AE reporting patterns of 5 years of 15 new molecular entities (NMEs and biologics used in oncology. This 5-year period started from the USFDA date of approval for the NMEs and biologics. The number of AEs reported for each of the drugs was plotted against time (years. The AE reporting patterns were specifically examined for the existence of the Weber effect. In addition, AE reporting rate patterns of 5 years of seven NMEs and biologics used in oncology were examined.Results: A total of 50,630 AE reports were logged in to the FAERS for all 15 drugs examined for AE reporting patterns. We observed five distinct AE reporting patterns for 15 drugs; however, none of the AE patterns were identical to the Weber effect. We did not observe a consistent AE reporting rate pattern for the seven drugs examined for AE reporting rates. With the exception of one drug (cetuximab, none of the drugs exhibited a second-year peak in AE reporting rates. This peak was not followed by continuous decline in AE reporting rate thereafter.Conclusion: This study does not support the existence of the Weber effect in AE reporting of oncology drugs.

    We describe the brain magnetic resonance imaging (MRI) abnormalities and neuropathologic findings of patients with Sturge-Weber syndrome and medically refractory epilepsy. We reviewed the clinical features, preoperative MRI studies, and pathologic findings of all patients with Sturge-Weber syndrome who underwent excisional surgery for intractable epilepsy at Boston Children's Hospital between 1993 and 2011. Eleven patients (male/female = 4/7) with Sturge-Weber syndrome were identified who underwent surgery for intractable epilepsy (mean age 13 ± 6.2 months), including hemispherectomy (n = 10) and focal cortical resection (n = 1). Mean age at seizure onset was 15 ± 11 weeks. Fifty-five percent (n = 6) of patients exhibited two different types of seizures, and 18% (n = 2) had three types of seizures. Focal clonic seizures were the most common type, occurring in nine patients; apnea was the second most common, occurring in four patients. Brain MRIs were reviewed in five patients. Histopathologic examination revealed varied degrees of cortical morphologic anomaly in seven of 11 patients. Overall, there were no abnormalities in the MRIs that corresponded directly with the pathologic findings except in one patient with polymicrogyria. In spite of pathologic findings of cortical anomalies in varied degrees, these findings could not be readily detected on brain MRIs. The failure to detect focal cortical dysplasia on MRIs may be attributable to the subtle microscopic nature of the abnormalities; in some of the older individuals, the imaging studies available for review were done during an advanced stage of the disease.

  12. Manual estimations of functionally graspable target objects adhere to Weber's law.

    The manual estimation task requires that participants separate the distance between their thumb and forefinger until they perceive it to match the size of a target object. Ganel and colleagues (Curr Biol 18:R599-R601, 2008a) demonstrated that manual estimations yield just-noticeable-difference (JND) scores that linearly increased with increasing target object size; that is, responses adhered to Weber's law and thus evince response mediation via relative and perception-based visual information. In turn, more recent work has reported that the size of a target object influences whether JNDs provide a reliable metric for evaluating the nature of the visual information supporting manual estimations. In particular, Bruno et al. (Neuropsychologia 91:327-334, 2016) reported that JNDs for 'large' target objects (i.e., 80 and 120 mm) violate Weber's law due to biomechanical limits in aperture opening. It is, however, important to recognize that the absolute size of the 'large' target objects employed by Bruno et al. may have exceeded some participants' functional aperture separation and resulted in a biomechanical strategy serving as the only viable response mode. Hence, the present investigation employed a manual estimation task wherein target object sizes were proportionately matched to decile increments (i.e., 10, 20, …, 70 and 80%) of individual participants' maximal aperture separation. Results showed that JNDs increased linearly with increasing target object size. Accordingly, we propose that manual estimations of target objects within a functionally 'graspable' range adhere to Weber's law and are mediated via relative and perception-based visual information.

    How does the magnitude of the exploration force influence the precision of haptic perceptual estimates? To address this question, we examined the perceptual precision for moment of inertia (i.e., an object's "angular mass") under different force conditions, using the Weber fraction to quantify perceptual precision. Participants rotated a rod around a fixed axis and judged its moment of inertia in a two-alternative forced-choice task. We instructed different levels of exploration force, thereby manipulating the magnitude of both the exploration force and the angular acceleration. These are the two signals that are needed by the nervous system to estimate moment of inertia. Importantly, one can assume that the absolute noise on both signals increases with an increase in the signals' magnitudes, while the relative noise (i.e., noise/signal) decreases with an increase in signal magnitude. We examined how the perceptual precision for moment of inertia was affected by this neural noise. In a first experiment we found that a low exploration force caused a higher Weber fraction (22%) than a high exploration force (13%), which suggested that the perceptual precision was constrained by the relative noise. This hypothesis was supported by the result of a second experiment, in which we found that the relationship between exploration force and Weber fraction had a similar shape as the theoretical relationship between signal magnitude and relative noise. The present study thus demonstrated that the amount of force used to explore an object can profoundly influence the precision by which its properties are perceived.

The characteristic facial port-wine stain, involving the first branch of the trigeminal nerve and the embryonic vasculature distribution in this area, leads to several ocular complications of the anterior segment and can involve the eyelids and conjunctiva. The posterior segment of the eyes is also affected with diffuse choroidal hemangiomas. However, the most frequent ocular comorbidity is glaucoma with a prevalence rate ranging from 30%–70%. Glaucoma is related to anterior chamber malformations, high episcleral venous pressure (EVP, and changes in ocular hemodynamics. Glaucoma can be diagnosed at birth, but the disease can also develop during childhood and in adults. The management of glaucoma in Sturge–Weber syndrome patients is particularly challenging because of early onset, frequently associated severe visual field impairment at the time of diagnosis, and unresponsiveness to standard treatment. Several surgical approaches have been proposed, but long-term prognosis for both intraocular pressure control and visual function remains unsatisfactory in these patients. Choroidal hemangiomas may also lead to visual impairment thorough exudative retinal detachment and macular edema. Treatment of exudative hemangioma complications is aimed at destructing the tumor or decreasing tumor leakage.

    Quantization has become a new way to investigate classical game theory since quantum strategies and quantum games were proposed. In the existing studies, many typical game models, such as the prisoner's dilemma, battle of the sexes, Hawk-Dove game, have been extensively explored by using quantization approach. Along a similar method, here several game models of opinion formations will be quantized on the basis of the Marinatto-Weber quantum game scheme, a frequently used scheme of converting classical games to quantum versions. Our results show that the quantization can fascinatingly change the properties of some classical opinion formation game models so as to generate win-win outcomes.

    CERN Document Server

    Kiwelekar, Arvind W

    2010-01-01

    A UML based metamodel for Bunge-Wand-Weber (BWW) ontology is presented. BWW ontology is a generic framework for analysis and conceptualization of real world objects. It includes categories that can be applied to analyze and classify objects found in an information system. In the context of BWW ontology, the metamodel is a representation of the ontological categories and relationships among them. An objective behind developing an object-oriented metamodel has been to model BWW ontology in terms of widely used notions in software development. The main contributions of this paper are a classification for ontological categories, a description template, and representations through UML and typed based models.

    Full Text Available Sturge-Weber syndrome (SWS is a rare, sporadic neurocutaneous syndrome characterized by a classical triad of facial port wine nevus, ipsilateral leptomeningeal angiomatosis (LAM and glaucoma. The incidence of SWS is 1/50,000 live births, although it is more often underreported. The incidence of SWS without facial nevus is not known, although very few patients without facial nevus have been reported. In these patients, the diagnosis of SWS is made by the findings of computed tomography, magnetic resonance imaging, and histopathology. Here, we report three patients with SWS from our cohort of 28 patients with SWS without facial nevus and discuss their clinical profile and outcome.

  2. Connection between Shannon's information theory and the Weber-Fechner law

    Information theory is generally considered to have been founded in 1948 by Claude E. Shannon in his seminal work, "A mathematical theory of communication." Shannon defined mathematically the amount of information transmitted over a channel. Meanwhile, psychophysics is the study of quantitative relations between psychological events and physical events or, more specifically, between sensations and the stimuli that produce them. It seems that Shannon's information theory bears no relation to psychophysics established by German scientist and philosopher Gustav Theodor Fechner. To our astonishment, it is possible that we combine two fields. And therefore we can measure mathematically perceptions of the physical stimuli applicable to the Weber-Fechner law.

    2017-02-01

    In this study, we present the parameters of the Stillinger-Weber (SW) potential for single-layer WSe2 and calculate its in-plane thermal conductivity using a reverse non-equilibrium molecular dynamics simulation. The parameters are fitted to the phonon dispersion curves from literature density functional perturbation theory and experimental structural properties. The set reproduces the phonon dispersion well. The in-plane thermal conductivity of single-layer WSe2 and its dependency on sample length and temperature are calculated and the results are in good agreement with experimental values. Our developed SW-type potential facilitates further investigations on thermal, mechanical and other properties of WSe2.

  4. Les Ecrits politiques de Max Weber: esquisse d’une lecture sociologique

    François Chazel

    2014-05-01

    Full Text Available The author argues that Max Weber in his Politische Schriften (from 1906 to 1919 is using a sociological approach to the prevailing problems of Russia and Germany, grounded on categories of his political sociology. Weber’s in-depth analysis of the Russian Revolution of 1905 and of its outcome brilliantly illustrates this approach. In the first of his memoirs, overviewing Russian society as a whole, he highlights the multiple impediments to a success of bourgeois democracy in Russia; in the second one, he points out the political factors, as symbolized by “pseudo-constitutionalism”, that caused the failure of the liberal Revolution. In his “Parliament and Government in a reorganized Germany”, Weber rests on the analysis of bureaucracy in his first “sociology of domination”, pointing out that bureaucracy is unavoidable in modern society as well as it threatens to be overpowering. It is therefore required, in Weber’s view, to build institutions assuming a counterpoising function: he first conferred this role on a strong parliament, on the model of the English Parliament. Then, after the fall of the Wilhelminian Empire, he emphasized the plebiscitary power of a Reichspräsident. As a whole, Weber’s analyses bring out the dilemma between oligarchy and democracy but also the subtle relations linking them in the context of political modernity. Oligarchy is a threat to democracy because bureaucracy’s power can, if not checked, extend into the political field and because political parties are more and more oligarchic organizations. Large-scale socialism can only worsen the situation and lead to “bureaucracy’s dictatorship”. Therefore, Weber argues for the setting up of counterweights on the societal level. There is a way out of Michels’ dilemma in the national competition between bureaucratized parties. Weber is faced again with an authoritarian danger when he emphasizes in his last political writings the plebiscitary

    Bohmian mechanics and Ghirardi-Rimini-Weber theory provide opposite resolutions of the quantum measurement problem: the former postulates additional variables (the particle positions) besides the wave function, whereas the latter implements spontaneous collapses of the wave function by a nonlinear and stochastic modification of the Schr\\"odinger equation. Still, both theories, when understood appropriately, share the following structure: They are ultimately not about wave functions but about matter moving in space, represented by either particle trajectories, fields on space-time, or a discrete set of space-time points. The role of the wave function then is to guide the motion of the matter.

    Full Text Available The purpose of this paper is to reconstruct Weber’s genealogy of the spirit of capitalism. Weber conceives the transition from the ethics of ascetic Protestantism to the spirit of capitalism as a process of secular-ization. The analysis of the origin of the spirit of capitalism will help illustrate the plurality of paths of secularization, highlighting their different orientation and their independent origin. The emancipation of the economic ethos from the religious fundaments can not be understood without recurring to a notion like that of rival subrogation: a notion irreducible and opposite to that of secularization.

  19. Operationalizing Max Weber's probability concept of class situation: the concept of social class.

    Science.gov (United States)

    Smith, Ken

    2007-03-01

    In this essay I take seriously Max Weber's astonishingly neglected claim that class situation may be defined, not in categorial terms, but probabilistically. I then apply this idea to another equally neglected claim made by Weber that the boundaries of social classes may be determined by the degree of social mobility within such classes. Taking these two ideas together I develop the idea of a non-categorial boundary 'surface' between classes and of a social class 'corridor' made up of all those people who are still to be found within the boundaries of the social class into which they were born. I call social mobility within a social class 'intra-class social mobility' and social mobility between classes 'inter-class social mobility'. I also claim that this distinction resolves the dispute between those sociologists who claim that late industrial societies are still highly class bound and those who think that this is no longer the case. Both schools are right I think, but one is referring to a high degree of intra-class social mobility and the other to an equally high degree of inter-class mobility. Finally I claim that this essay provides sociology with only one example among many other possible applications of how probability theory might usefully be used to overcome boundary problems generally in sociology.

Weber predicted that modernisation, as represented by the rationalisation process which is unstoppable phenomena for modern world lead the changing process of charismatic authority into other forms of authorities, especially the legal-rational one. By describing the dynamics of Kyai’s charismatic authority within the pesantren milieu, the rationalisation process tends to enhance the existence of charismatic authority of kyai. Based on a case study of a famous traditional pesantren in Yogyakarta, this paper elaborates the process of rationalisation describes how all instruments of traditional pesantren, including those that are resulted from the process, have contribution in preserving and maintaining the charismatic authority o kyai. Most members of traditional pesantren even believe that the quality of charisma, which is laid on the foundation of supernatural power, can be transmitted to the next successor through the institutionalisation of practices to gain that power.

  1. Sturge-Weber Syndrome Associated with Monolateral Ocular Melanocytosis, Iris Mammillations, and Diffuse Choroidal Haemangioma

    Full Text Available We present the case of a 12-year-old boy with Sturge-Weber syndrome and ocular melanocytosis who presented with bilateral naevus flammeus of the face and hyperpigmentation of the right iris associated with ipsilateral iris mammillations. The patient had glaucoma and a diffuse choroidal haemangioma of the right eye. Optical coherence tomography of the anterior segment confirmed iris hyper-pigmentation and did not show abnormalities of the chamber angle structures. B-scan ultrasonography and enhanced depth imaging optical coherence tomography were performed and showed a marked difference in thickness and reflectance between the right and left choroid. Visual field examinations with perimetry showed early defects in the right eye. Peripapillary optical coherence imaging showed borderline values of retinal nerve fibre layer thickness reduction in the right eye. Sturge-Weber syndrome associated with ocular melanocytosis and iris mammillations is an extremely rare condition. This paper highlights the role of multi-imaging methods in the enhanced evaluation of rare diseases towards choosing the most appropriate management strategies and improving the follow-up of patients over time.

    A pintle injector is advantageous for throttling a liquid rocket engine and reducing engine weight. This study explores the effects of momentum ratio and Weber number at various injection conditions on spray characteristics of the pintle injector for liquid-gas propellants. A liquid sheet is injected from a center pintle nozzle and it is broken by a gas jet from an annular gap. The pressure drops of propellants, and the pintle opening distance were considered as control variables; using 0.1 ˜1.0 as a bar for the pressure drop of the liquid injection, a 0.01˜0.2 bar for the pressure drop of gas jet and a 0.2˜ 1.0 mm for the pintle opening distance. The discharge coefficient was decreased linearly before the pintle opening distance of 0.75 mm and then, the coefficient was slightly increased. Spray images were captured by a CMOS camera with high resolution. Then, the shadow and reflected images were analyzed. Spray distributions were measured by a patternator with an axial distance of 50 mm from a pintle tip. Finally, the spray half angles had an exponentially decreasing correlation as a momentum ratio divided by the Weber number. Also, the spray half angles from the spray distribution were underestimated compared to those measured from the captured images.

    The Klippel-Trenaunay-Weber syndrome is characterized by skeletal and soft-tissue hypertrophy, segmentally distributed cutaneous nevi, and vascular anomalies. Only a few cases of this syndrome associated with hemimegalencephaly have been reported previously. However, we have experienced such a case of Klippel-Trenaunay-Weber syndrome with hemicranial hypertrophy, and so have analyzed this case from the neuroradiological point of view. The patient was a 6-month-old female with hemihypertrophy and hemimegalencephaly on the same, right side. A skull X-ray showed that the skull and facial bones were all hypertrophic on the right side and that all the sutures were open. A CT scan demonstrated that all the intracranial structures, including the ventricle on the right, were larger than those on the left. On the right side, we noticed a periventricular low-density area and spotted a calcified high-density region adjacent to the anterior horn of the lateral ventricle. Metrizamide CT cisternography exhibited ventricular stasis at 6 hours and a delayed clear-up in the subarachnoid space over the cerebral convexity in 24 hours. When we used the inversion recovery method on magnetic resonance imaging, the white matter on the right, especially in the periventricular area, was shown by a lower signal intensity than was that on the left. This could be thought to indicate the poor progress of the myelination process on the right side of the cerebrum.

    The pathophysiology of Sturge-Weber syndrome is poorly understood, and ear, nose, and throat involvement is possible. These issues can result in frequent illnesses or airway obstruction, affecting patients' neurologic status. Patients with definite brain involvement who reported potential ear, nose, and throat issues on intake questionnaires underwent retrospective reviews of their medical records. We examined the relationships between these issues, secondary surgical interventions, and patients' neurologic status. The most common complaints involved the sinuses and frequent ear infections. Six patients underwent placement of ear tubes, leading to improvements in migraines and stroke-like episodes in one patient, and improved seizure control in four others. Obstructive sleep apnea was confirmed in three patients who underwent sleep studies. Tonsil or adenoid removal occurred in another three patients. Surgery resulted in marked improvements regarding excessive drooling, daytime sleepiness, and breathing problems. These findings suggest that ear, nose, and throat problems occur frequently in patients with Sturge-Weber Syndrome, and when repeated ear infections are associated with uncontrolled seizures, early placement of ear tubes may be beneficial. Furthermore, patients with facial tissue hypertrophy may be at risk for obstructive sleep apnea, and should be appropriately evaluated.

    2014-03-01

    Full Text Available El artículo analiza cómo se recibieron las ideas de Max Weber en las primeras décadas de la institucionalización de la sociología en Brasil, y argumenta que la apropiación de los postulados del autor alemán se hizo a partir de las cuestiones propias de la sociología brasileña. Este punto de vista permitió observar que proposiciones centrales de la sociología weberiana, como, por ejemplo, la formulación de los tipos ideales y del sentido de la ciencia, se recibieron con mucha parsimonia y se reelaboraron a medida que los textos del autor se fueron leyendo en contraste con otros autores. Inicialmente, se retoman textos de la revista Sociología; en seguida se discute la valorización de las proposiciones de Hans Freyer y Karl Mannheim en detrimento de las posiciones de Max Weber sobre el papel del sociólogo y, finalmente, se trata la controversia sobre los tipos ideales, liderada por Maria Sylvia de Carvalho Franco, que involucra los escritos de Florestan Fernandes y Fernando Henrique Cardoso.

    During the cooking process of Agave tequilana Weber var. azul to produce tequila, besides the hydrolysis of inulin to generate fermentable sugars, many volatiles, mainly Maillard compounds, are produced, most of which may have a significant impact on the overall flavor of tequila. Exudates (agave juice) from a tequila company were collected periodically, and color, Brix, fructose concentration, and reducing sugars were determined as inulin breakdown took place. Maillard compounds were obtained by extraction with CH(2)Cl(2), and the extracts were analyzed by GC-MS. Increments in color, Brix, and reducing sugars were observed as a function of time, but a decrease in fructose concentration was found. Many Maillard compounds were identified in the exudates, including furans, pyrans, aldehydes, and nitrogen and sulfur compounds. The most abundant Maillard compounds were methyl-2-furoate, 2,3-dihydroxy-3,5-dihydro-6-methyl-4(H)-pyran-4-one, and 5-(hydroxymethyl)furfural. In addition, a series of short- and long-chain fatty acids was also found. A large number of the volatiles in A. tequilana Weber var. azul were also detected in tequila extracts, and most of these have been reported as a powerful odorants, responsible for the unique tequila flavor.

    Full Text Available Stewart-Bluefarb acroangiodermatitis is the occurrence of pseudo-kaposiform changes with an underlying arterio-venous malformation. Parkes-Weber syndrome is a triad of arterio-venous malformation with varicose veins with bony and soft-tissue hypertrophy involving the extremity. A 13 year-old-female presented with ulcerated growth with bleeding episodes on right leg since past four years. A reddish discoloration over right leg was noticed at four years of age which remained unchanged until nine years of age, after which it showed rapid increase in size along with disproportionate increase in length and girth of right lower limb. Examination revealed hyperpigmented soft verrucous plaque over the right lower one-third of leg, along with presence of ulcers and dilated tortuous veins in the right lower leg with thrill and bruit over the right popliteal and inguinal region. A differential diagnosis of verrucous hemangioma and arterio-venous malformation with pseudo-kaposiform change was considered. Skin biopsy showed multiple fenestrated capillaries with perivascular lymphocyte infiltrate suggestive of capillary malformations. X-ray showed osteolytic defect in right tibia. Duplex ultrasound and magnetic resonance imaging of right leg showed multiple fast flowing small and medium sized arterio-venous malformations of small to moderate size. Thus, on the basis of clinical and radiological features, we made a diagnosis of Stewart-Bluefarb type of acroangiodermatitis with Parkes-Weber syndrome. She was managed conservatively with compression stockings.

    This study describes the imaging features of the intrahepatic portohepatic venous (PHV) shunt, which is a potential cause of portosystemic encephalopathy in Rendu-Osler-Weber disease. Six patients with Rendu-Osler-Weber disease (two men, four women; age range 42-73 years) were retrospectively studied. There were two from one family and three from another family. Of these patients, one was diagnosed with definitive portosystemic encephalopathy because of a psychiatric disorder. We retrospectively reviewed the radiological examinations, including abdominal angiography (n=6), three-phase dynamic helical computed tomography (CT; n=3), and conventional enhanced CT (n=1). In one patient, CT during angiography and CT angioportography were also performed. Evaluation was placed on the imaging features of intrahepatic PHV shunts. On angiography, intrahepatic PHV shunts showing multiple and small shunts <5 mm in diameter in an apparent network were detected in all patents. In two patients, a large shunt with a size of either 7 or 10 mm was associated. These intrahepatic PHV shunts were predominantly distributed in the peripheral parenchyma. Intrahepatic PHV shunts would be characterized by small and multiple shunts in an apparent network on the periphery with or without a large shunt. (orig.)

    Sturge-Weber syndrome (SWS) is a rare congenital sporadic disease with neuro-ocular and cutaneous vascular findings. Clinically, the full-blown condition consists of a facial port-wine stain (PWS) the V1 facial trigeminal skin area, alone or in combination with V2 and V3 PWS, seizures and ocular abnormalities (glaucoma and choroidal angioma). Radiologically, a leptomeningeal (pial) capillary and venous malformation, mostly located in the parieto-occipital area, cerebral atrophy and calcifications are demonstrated. An ipsilateral enlarged choroid plexus may be an early anatomic symptom. Development neuro-diagnostic technique for the screening of infants with an at-risk V1 PWS, as well as for the follow-up of patients with evidence SWS. Accelerated myelination in the involved hemisphere may be early diagnostic feature before 6 months of age. Later, hyperintensity of white matter on T2 is considered a symptom of gliosis. Clinically, progression of the diseases is associated with anatomic changes and correlates with the extent of the pial vascular anomaly, extent and severity of cerebral atrophy, and white matter abnormalities. A neonatal neuro-imaging work-up, using CT or MRI, may not demonstrate the pial anomaly and should be repeated after 6 to 12 months in an at-risk infant with V1 PWS. (authors)

    2007-07-01

    Full Text Available Max Weber’s thought was known in Argentina’s scholarly milieu in the years preceding the first translations into Spanish of his works, Historia Económica General and Economía y Sociedad, both edited by Fondo de Cultura Económica in 1942 and 1944 respectively. The first references to Weber ´s oeuvre appeared at the beginning of the ‘30s in an intellectual context characterized by the revolt against positivism and the diffusion of German thinking in general, and its sociological thinking, in particular. During that period, sociology was an emerging field and sociologists faced the task of justifying their practice and kinds of approach. Nevertheless, there were different views of the discipline each of which articulating aspecific interpretation of Weber ´s contribution. Given this situation, we may wonder, who was Weber for argentine readers? Which themes of his vast work were selected in the context of local intellectual concerns? In sum, this paper explores the different interpretations of Max Weber ideas showing how these became articulated with the different conceptions of the discipline struggling for supremacy in a given, still incipient, disciplinary field.

    Full Text Available Max Weber foi precursor em apresentar as características e as consequências do processo de burocratização nas esferas sociais, sobretudo, no Estado. Em relação à democracia, Weber não deixou uma definição explícita em seus escritos, no entanto, com frequência a concepção de democracia como método para eleger líderes seja remetida a ele. O presente artigo tem como objetivo geral analisar a relação que Weber estabeleceu entre a democracia e a burocracia, dois conceitos que se entrecruzaram em vários de seus textos como fenômenos inerentes à sociedade moderna e ao processo de racionalização. Debruçarmo-nos sobre os escritos teóricos de Weber para os estudos ligados à burocracia é fundamental para compreendermos o funcionamento dos Estados modernos, assim como esmiuçar a concepção weberiana acerca da democracia. Concepção, esta, que se tornou hegemônica nas últimas décadas e que vem sendo contestada pelos movimentos populares que almejam participar de maneira mais direta nas decisões político-administrativas do Estado.

    Full Text Available This text has as objective to understand the differences between the social ethics of Luther and the conceptions on the protestant ethics developed by Max Weber. The lutheran social ethics do not enroll in the religious ascetism of the pietism and in the ethical vision of the calvinist protestantism of the analysis of Max Weber on the protestant ethics. The thesis of Weber does not allow to credit to the social ethics of Luther bonds with the spirit of the development of the capitalism. The proper Weber, in moment, believes that the spirit of the capitalism if must the influences of the Reformation Lutheran or that the capitalism as system is a product of the Reformation. Therefore, a conception of lutheran ethics, established in the social ethics of Luther, remains as important instrument of critical in a society in which the human being comes losing its ethical referent and its citizencommunitarian base for the absence of the practical learning of these values, for being it delivers to the individualism and he process of coisificação accomplished for the industrial capitalism and its current marketing face that an limited citizenship imposes the majority of the population of the planet, lead for those that they control the economy and the politics (the money and the power and for the ethics of the market.

    Molecular dynamics simulations are used to contrast the supercooling and crystallization behaviour of monatomic liquids that exemplify the transition from simple to anomalous, tetrahedral liquids. As examples of simple fluids, we use the Lennard-Jones (LJ) liquid and a pair-dominated Stillinger-Weber liquid (SW16). As examples of tetrahedral, water-like fluids, we use the Stillinger-Weber model with variable tetrahedrality parameterized for germanium (SW20), silicon (SW21), and water (SW23.15 or mW model). The thermodynamic response functions show clear qualitative differences between simple and water-like liquids. For simple liquids, the compressibility and the heat capacity remain small on isobaric cooling. The tetrahedral liquids in contrast show a very sharp rise in these two response functions as the lower limit of liquid-phase stability is reached. While the thermal expansivity decreases with temperature but never crosses zero in simple liquids, in all three tetrahedral liquids at the studied pressure, there is a temperature of maximum density below which thermal expansivity is negative. In contrast to the thermodynamic response functions, the excess entropy on isobaric cooling does not show qualitatively different features for simple and water-like liquids; however, the slope and curvature of the entropy-temperature plots reflect the heat capacity trends. Two trajectory-based computational estimation methods for the entropy and the heat capacity are compared for possible structural insights into supercooling, with the entropy obtained from thermodynamic integration. The two-phase thermodynamic estimator for the excess entropy proves to be fairly accurate in comparison to the excess entropy values obtained by thermodynamic integration, for all five Lennard-Jones and Stillinger-Weber liquids. The entropy estimator based on the multiparticle correlation expansion that accounts for both pair and triplet correlations, denoted by Strip, is also studied. Strip is a

    A number of studies have reported that grasps and manual estimations of differently sized target objects (e.g., 20 through 70 mm) violate and adhere to Weber's law, respectively (e.g., Ganel et al. 2008a, Curr Biol 18:R599-R601)-a result interpreted as evidence that separate visual codes support actions (i.e., absolute) and perceptions (i.e., relative). More recent work employing a broader range of target objects (i.e., 5 through 120 mm) has laid question to this claim and proposed that grasps for 'larger' target objects (i.e., >20 mm) elicit an inverse relationship to Weber's law and that manual estimations for target objects greater than 40 mm violate the law (Bruno et al. 2016, Neuropsychologia 91:327-334). In accounting for this finding, it was proposed that biomechanical limits in aperture shaping preclude the application of Weber's law for larger target objects. It is, however, important to note that the work supporting a biomechanical account may have employed target objects that approached -or were beyond-some participants' maximal aperture separation. The present investigation examined whether grasps and manual estimations differentially adhere to Weber's law across a continuous range of functionally 'graspable' target objects (i.e., 10,…,80% of participant-specific maximal aperture separation). In addition, we employed a method of adjustment task to examine whether manual estimation provides a valid proxy for a traditional measure of perceptual judgment. Manual estimation and method of adjustment tasks demonstrated adherence to Weber's law across the continuous range of target objects used here, whereas grasps violated the law. Thus, results evince that grasps and manual estimations of graspable target objects are, respectively, mediated via absolute and relative visual information.

    Full Text Available The Weber Center at Judson University, a mixed mode, naturally ventilated building in a continental climate, has been in operation for just over a year, with initial occupancy in August 2007. This paper compares the design objectives and building performance expectations against the first yearof actual energy consumption in a first of a series of post-occupancy evaluations. The paper contrasts the building performance with general user satisfaction and perceptions of comfort through a post occupancy evaluation of user surveys and interviews. The innovations involved in this building, particularly mechanical strategies atypical in contemporary practice within this climate and region, have introduced some interesting problems that have been documented in the post-occupancy evaluation process, while confirming many of the original intentions of the design.

    2015-07-01

    Full Text Available In this paper, we examine the heuristic utility of Weber's notion of meaning to explain the perception of immigrants in the United States, particularly undocumented immigrants. The methodological rule implying that the understanding of the meaning of such perceptions can only be achieved through the notion of structure and the theory of socialization, as presented by Jorge Bustamante, is contested. We argue that with the notion of meaning comes into play the conception of an individual motivated by subjective reasons when perceiving immigrants as X or Y, and that those reasons, far from being justifications, have a real, objective basis. We advance a comprehensive framework of law SB1070 to attempt to elucidate some of the reasons that motivate involved actors’ approval or disapproval of this law.

Klippel-Trenaunay syndrome (KTS is a rare congenital malformation associated with cutaneous vascular malformation, bony or soft tissue hypertrophy and venous varicosities in the affected limb. Although some cases have been reported in the literature, an overlap between these two phakomatoses is extremely rare and they have systemic and ocular affects. Here, we present a case showing the properties of both SWS and KTS and having interesting ophthalmological findings. This case is presented to emphasize that eye related complications might also be seen in these syndromes.

    Full Text Available Weber and Schumpeter: the Economic action of the entrepreneur. Is there any specificity to be raised in the relations established between entrepreneurs and institutions? Recently, the term entrepreneurship is being widely employed. Enterprising is not anymore a restricted activity to the private sector, but also the Third Sector and the Public Administration. It does not only circumscribe the space of innovation, but also of the adapting changes. In this sense, such elastic concept runs the risk to lose consistency. It seems to be appropriate, therefore, to rescue the meaning that many authors, considered classic in Social Sciences, had attributed to the subject, to show that, although deep socioeconomic transformations occurred since Schumpeter wrote the Theory of the Economic Development, is still necessary to emphasize a basic dimension of the enterprising action: resistance and institutional conflict.

    2016-08-01

    Full Text Available By the combination of the modified half-linear Prüfer method and the Riccati technique, we study oscillatory properties of half-linear differential equations. Taking into account the transformation theory of half-linear equations and using some known results, we show that the analysed equations in the Riemann–Weber form with perturbations in both terms are conditionally oscillatory. Within the process, we identify the critical oscillation values of their coefficients and, consequently, we decide when the considered equations are oscillatory and when they are non-oscillatory. As a direct corollary of our main result, we solve the so-called critical case for a certain type of half-linear non-perturbed equations.

    Full Text Available The FOUCAULTian governmentality approach, in relying on a teleology—the ultimate purpose of human endeavour is the quest for ever-growing human reason, a reason that is the universal basis of moral judgements, especially moral judgements about political and legal actions—leads not to description, explanation and the possible identification of causes, but to critique, to the inappropriate conflation of, on the one hand, description, explanation and the identification of causes with, on the other, political criticisms sourced in the teleology. Drawing on some of WEBER's methodological insights, an argument is developed that critical discourse analysis, in taking on the FOUCAULTian approach, gives up the best traditions of description, explanation and the identification of causes in favour of the expression, in many different forms, of the teleology.

    To clarify certain nonlinear properties of strong gravitational field, we investigate cylindrically symmetric gravitational waves that are localized as regular wave packets in the space of radial and time coordinates. The waves are constructed by applying a certain kind of harmonic mapping method to the seed solutions with linear polarization, which are generalizations of the solution representing a cylindrical gravitational pulse wave discussed by Weber, Wheeler, and Bonnor. The solutions obtained here, though their form is rather simple, show occurrence of strong mutual conversion between a linear mode and a cross mode apparently. The single localized wave shows the conversion in the vicinity of the symmetric axis where the self-interaction is strengthened, and the collision between multiple waves also causes the conversion. These phenomena can be thought to be the emergence of genuine nonlinearity that the Einstein gravity holds. Finally we discuss a simple, but interesting application of the solutions to the case of the Einstein-Maxwell system.

    Full Text Available We present summer Na-densities and atmospheric temperatures measured 80 to 110 km above the Arctic Lidar Observatory for Middle Atmosphere Research (ALOMAR. The Weber Na Lidar is part of ALOMAR, located at 69° N in Norway, 150 km north of the Arctic Circle. The sun does not set here during the summer months, and measurements require a narrowband Faraday Anomalous Dispersion Optical Filter (FADOF.

    We discuss an observed sudden enhancement in the Na number density around 22:00 UT on 1 to 2 June 2006. We compare this observation with previous summer measurements and find a frequent appearance of Na number density enhancements near local midnight. We describe the time of appearance, the altitude distribution, the duration and the strength of these enhancements and compare them to winter observations. We investigate possible formation mechanisms and, as others before, we find a strong link between these Na number density enhancements and sporadic E layers.

    Full Text Available Background: While various radiographic parameters and application of manual/gravity stress have been proposed to elucidate instability for Weber B fibula fractures, the prognostic capability of these modalities remains unclear. Determination of anatomic positioning of the mortise is paramount. We propose a novel view, the Gravity Reduction View (GRV, which helps elucidate non-anatomic positioning and reducibility of the mortise.Methods: The patient is positioned lateral decubitus with the injured leg elevated on a holder with the fibula directed superiorly. The x-ray cassette is placed posterior to the heel, with the beam angled at 15˚ of internal rotation to obtain a mortise view. Our proposed treatment algorithm is based upon the measurement of the medial clear space (MCS on the GRV versus the static mortise view (and in comparison to the superior clear space (SCS and is based on reducibility of the MCS. A retrospective review of patients evaluated utilizing the GRV was performed.Results: 26 patients with Weber B fibula fractures were managed according to this treatment algorithm. Mean age was 50.57 years old (range: range:18-81, SD=19. 17 patients underwent operative treatment and 9 patients were initially treated nonoperatively. 2 patients demonstrated late displacement and were treated surgically. Using this algorithm, at a mean follow-up of 26 weeks, all patients had a final MCS that was less than the SCS (final mean MCS 2.86 mm vs. mean SCS of 3.32 indicating effectiveness of the treatment algorithm.Conclusion: The GRV is a novel radiographic view in which deltoid competency, reducibility and initial positioning of the mortise are assessed by comparing a static mortise view with the appearance of the mortise on the GRV. We have developed a treatment algorithm based on the GRV and have found it to be useful in guiding treatment and successful at achieving anatomic mortise alignment.

    Full Text Available Tequila is one of the most famous drinks on a national and worldwide level. It is obtained from the Agave tequilana Weber plant, better known as Agave Azul. The part of the plant used for making tequila is the core. Once the cores are cut, they are taken away to an oven where a cooking operation is made, this with the object of degrading the complex sugars of the core into simple sugars that can be used as yeasts in the fermentation process. The principal complex carbohydrate present in agave is inulin, which is a polymeric fructose with a terminal glucose residue. When the inulin is degraded by action of the juice´s acidity and the heat of cooking, fructose and glucose are obtained. Next, the cores are milled to extract the juice which is placed in vats and inoculated with a yeast culture of Saccharomyces cerevisiae, responsible for the fermentation of the sugars present in the juice. After fermentation, the juice is distilled to obtain ethanol and vinazes (a mixture of dead yeasts, nonfermentable sugars, and minerals. Tequila can be bottled immediately after distillation or it can be aged in the wooden casks wich confer characteristic flavor and color to tequila.El tequila es una de las bebidas más famosas a nivel nacional y mundial. Se obtiene de la planta Agave tequilana Weber, mejor conocido como Agave azul. La parte de la planta que es utilizada para la elaboración del tequila es la piña.

    Full Text Available Apresentamos Max Weber como um dos sociólogos e historiadores mais importantes dentre aqueles que se dedicaram ao estudo do fenômeno religioso. Na verdade, é possível afirmar que a análise da religião compreende um dos aspectos mais fundamentais de sua obra sócio-histórica. De modo geral, esse tema aparece em seus textos de duas maneiras diferentes, quais sejam: enquanto um objeto analisado em sua singularidade e enquanto uma manifestação social que influencia de maneira significativa os demais aspectos da vida comunitária. Aqui, observamos como ele muniu-se de um método particular e o utilizou como parâmetro para compreender historicamente a religião. Ao se debruçar sobre as religiões mundiais (confucionismo-taoísmo, judaísmo-cristianismo e hinduísmo-budismo, Weber estuda a racionalização cultural de suas cosmovisões. Todavia, para ele, a influência da religião sobre a vida prática varia muito segundo o caminho da salvação/libertação que é prescrito e segundo a qualidade psíquica (ou imaginada da salvação que se pretende alcançar. Palavras-chave: Max Weber; Religião; Religiões Mundiais; Racionalização.   AbstractWe present Max Weber as one of the most important sociologists and historians among those who dedicated themselves to the study of the religious phenomenon. Actually, it is possible to say that the analysis of religion involves one of the most fundamental aspects of his socio-historical work.

Here, we observe how he equipped himself with a particular method, rescued Kantian rationality and applied it as a parameter to historically understand religion. While he dedicated himself to study world religions (Confucianism-Taoism, Judaism-Christianity, and Hinduism

    2016-08-01

    Against the background of Max Weber's and Karl Jaspers' outstanding historical contributions to the conceptual development of different typologies, the importance of a psychiatric typology is examined. The term "ideal type" was introduced into social science by Weber as an analytical construct to describe and classify cultural phenomena. This concept was adopted for the psychiatric context by Jaspers who proposed to establish a typological system in the field of psychotic disturbances without an organic correlate. He emphasized the importance of the course of psychopathological symptoms for such a typological system. The concept of typology can be regarded as a promising heuristic approach in psychiatry, providing a classification system for complex psychopathological symptoms. Even though several historic typologies exist in psychopathology, their usefulness in the fields of therapy and prognosis needs to be critically assessed. Also, new typologies will have to be developed, taking into account neurobiological knowledge now available.

    Full Text Available Dans cet article, on oppose la pensée de Max Weber à celle de Friedrich Nietzsche à propos de l'Occident moderne, en prenant comme point de départ les notions de "mort de Dieu" et de "désenchantement du monde".

    We use molecular dynamics simulations to compare and contrast the liquid-state anomalies in the Stillinger-Weber models of monatomic water (mW), silicon (Si), and germanium (Ge) over a fairly wide range of temperatures and densities. The relationships between structure, entropy, and mobility, as well as the extent of the regions of anomalous behavior, are discussed as a function of the degree of tetrahedrality. We map out the cascade of density, structural, pair entropy, excess entropy, viscosity, and diffusivity anomalies for these three liquids. Among the three liquids studied here, only mW displays anomalies in the thermal conductivity, and this anomaly is evident only at very low temperatures. Diffusivity and viscosity, on the other hand, show pronounced anomalous regions for the three liquids. The temperature of maximum density of the three liquids shows re-entrant behavior consistent with either singularity-free or liquid-liquid critical point scenarios proposed to explain thermodynamic anomalies. The order-map, which shows the evolution of translational versus tetrahedral order in liquids, is different for Ge than for Si and mW. We find that although the monatomic water reproduces several thermodynamic and dynamic properties of rigid-body water models (e.g., SPC/E, TIP4P/2005), its sequence of anomalies follows, the same as Si and Ge, the silica-like hierarchy: the region of dynamic (diffusivity and viscosity) anomalies encloses the region of structural anomalies, which in turn encloses the region of density anomaly. The hierarchy of the anomalies based on excess entropy and Rosenfeld scaling, on the other hand, reverses the order of the structural and dynamic anomalies, i.e., predicts that the three Stillinger-Weber liquids follow a water-like hierarchy of anomalies. We investigate the scaling of diffusivity, viscosity, and thermal conductivity with the excess entropy of the liquid and find that for dynamical properties that present anomalies there is no

    Full Text Available Background: The goal of managing the comminuted fracture of lateral malleolus is to restore length, rotation and alignment which might be more challenging with extensive comminution around the area of the distal tip. The common osteosynthesis techniques such as the one-third tubular plate, tension band wiring, K-wires, screws, or intramedullary nail may be insufficient in cases with a comminuted lateral malleolus. The anatomical hook plate is an alternative implant in such cases. We present our results of the comminuted lateral malleolar fractures (Weber A, B, managed by open reduction and internal fixation (ORIF with an anatomical hook plate of lateral malleolus (Königsee Implant Company, Germany. Materials and Methods: We retrospectively reviewed 20 patients of comminuted fracture of distal lateral malleolus between 2008 and 2010. There were 12 males and 8 females, right side was involved in 18 patients and left in 2. The mean age was 51.9 years (range 18-75 years. The fractures were categorized by Denis-Weber classification type A (n=1, B1 (n=1, B2 (n=13 and B3 (n=5. Nineteen cases were of closed injury and one of open injury (Gustilo Anderson type II. These patients underwent ORIF with a lateral malleolus anatomical hook plate. Followup including radiographs and clinical examinations were performed. The American Orthopedic Foot and Ankle Society (AOFAS ankle hindfoot scores were documented at followups. Results: The mean followup was 21.4 months (range 16-27 months. The average AOFAS score was 94.3 (range 78-100 points. A stable anatomic reduction and bony union were obtained in all the cases. The average time was 3.1 months (range 2.5-4 months. Four cases had complications like posttraumatic osteoarthritis, hardware impingement and superficial wound infection. Conclusion: A reasonably good stability can be obtained in distal most comminuted fractures of lateral malleolus with a lateral malleolus anatomical hook plate. We believe this

    Full Text Available Klippel Trenaunay Weber syndrome (KTWS is a rare disease characterized by hemihypertrophy, variceal enlargement of the veins, and arteriovenous (AV malformations. Renal involvement in KTWS is not known except in rare case reports. Herein, we present a case of KTWS with unilateral polycystic kidney. A 52-year-old male was admitted due to pain left lumbar region for the last three months. The physical findings were increased diameter and increased length of the left leg compared with the right one, diffuse variceal enlargements on left leg, portwine stain on left side on neck, thorax, abdomen, left upper limb and left lower limb and a few hemangiomatous lesions on the left leg. Radiographic findings were cystic lesions in the left kidney, varicose veins in left leg, and hypertrophy of the soft tissues of the proximal left leg. Color Doppler of left lower limb showed incompetence of the saphenofemoral junction. He was diagnosed to have KTWS with these findings. Renal function tests of the patient were in the normal range. Patient's only complain was left lumbar region pain, mild in intensity. Patient was managed symptomatically. [Int J Res Med Sci 2016; 4(5.000: 1760-1762

    This case involves a possible complication of excessive bleeding or rupture of hemangiomas. Problems and anesthetic management of the patient are discussed. A 35-year-old man with Sturge-Weber syndrome was to undergo teeth extraction and gingivectomy. Hemangiomas covered his face and the inside of the oral cavity. We used intravenous conscious sedation with propofol and N2O-O2 to reduce the patient's emotional stress. It was previously determined that stress caused marked expansion of this patient's hemangiomas. Periodontal ligament injection was chosen as the local anesthesia technique. Teeth were extracted without excessive bleeding or rupture of hemangiomas, but the planned gingivectomies were cancelled. Deep sedation requiring airway manipulation should be avoided because there are possible difficulties in airway maintenance. Because this was an outpatient procedure, propofol was selected as the sedative agent primarily because of its rapid onset and equally rapid recovery. Periodontal ligament injection with 2% lidocaine containing 1: 80,000 epinephrine was chosen for local anesthesia. Gingivectomy was cancelled because hemostasis was challenging. As part of preoperative preparation, equipment for prompt intubation was available in case of rupture of the hemangiomas. The typically seen elevation of blood pressure was suppressed under propofol sedation so that expansion of the hemangiomas and significant intraoperative bleeding was prevented. Periodontal ligament injection as a local anesthetic also prevented bleeding from the injection site.

    Multimodal medical image fusion (MIF) plays an important role in clinical diagnosis and therapy. Existing MIF methods tend to introduce artifacts, lead to loss of image details or produce low-contrast fused images. To address these problems, a novel spiking cortical model (SCM) based MIF method has been proposed in this paper. The proposed method can generate high-quality fused images using the weighting fusion strategy based on the firing times of the SCM. In the weighting fusion scheme, the weight is determined by combining the entropy information of pulse outputs of the SCM with the Weber local descriptor operating on the firing mapping images produced from the pulse outputs. The extensive experiments on multimodal medical images show that compared with the numerous state-of-the-art MIF methods, the proposed method can preserve image details very well and avoid the introduction of artifacts effectively, and thus it significantly improves the quality of fused images in terms of human vision and objective evaluation criteria such as mutual information, edge preservation index, structural similarity based metric, fusion quality index, fusion similarity metric and standard deviation.

    The present study examined the intellectual and adaptive functioning in a sample of children and young adults with Sturge-Weber Syndrome (SWS). A total of 80 research participants from a SWS study database underwent full neurological evaluation as part of their participation or concurrent medical care. Twenty-nine of the participants received neuropsychological evaluations. Analyses indicated no significant demographic or neurological differences between those who did and did not receive neuropsychological evaluations. Overall, the neuropsychological evaluation sample displayed significantly lower functioning relative to published normative data across domains of intellectual and adaptive functioning. Thirty-two percent of the sample displayed impaired performance (standard score ≤ 75) in intellectual functioning and 58% displayed impaired performance in adaptive functioning. Hemiparesis status independently predicted overall adaptive functioning while seizure frequency independently predicted overall intellectual functioning. Younger participants displayed significantly higher (more intact) ratings in adaptive functioning compared to older participants, specifically in overall adaptive functioning, motor skills, and community living skills. A composite measure of neurological status (SWS-NRS) incorporating seizure and hemiparesis status effectively distinguished between individuals with impaired or nonimpaired adaptive and intellectual functioning and showed promise as a screening method for identifying individuals with more involved intellectual and/or adaptive needs.

    Sturge-Weber syndrome (SWS) is a vascular neurocutaneous disorder that results from a somatic mosaic mutation in GNAQ, which is also responsible for isolated port-wine birthmarks. Infants with SWS are born with a cutaneous capillary malformation (port-wine birthmark) of the forehead or upper eyelid which can signal an increased risk of brain and/or eye involvement prior to the onset of specific symptoms. This symptom-free interval represents a time when a targeted intervention could help to minimize the neurological and ophthalmologic manifestations of the disorder. This paper summarizes a 2015 SWS workshop in Bethesda, Maryland that was sponsored by the National Institutes of Health. Meeting attendees included a diverse group of clinical and translational researchers with a goal of establishing research priorities for the next few years. The initial portion of the meeting included a thorough review of the recent genetic discovery and what is known of the pathogenesis of SWS. Breakout sessions related to neurology, dermatology, and ophthalmology aimed to establish SWS research priorities in each field. Key priorities for future development include the need for clinical consensus guidelines, further work to develop a clinical trial network, improvement of tissue banking for research purposes, and the need for multiple animal and cell culture models of SWS.

    Full Text Available Sturge-Weber syndrome (SWS, sometimes referred to as encephalotrigeminal angiomatosis, is a rare congenital neurological and skin disorder. It is one of the phakomatoses which is often associated with port-wine stains of the face, glaucoma, seizures, mental retardation, and ipsilateral leptomeningeal angioma. It is characterized by proliferation of arteries of the brain, resulting in multiple angiomas that occur on the same side due to arteriovenous malformations. Normally, only one side of the head is affected and mainly results from the errors in both the mesodermal and ectodermal development. Here, we report a rare case of SWS having oral and facial manifestations, where an 8-year-old boy had actually come for treatment of swollen gums, and on examination, we found that he had typical signs and symptoms of this rare developmental anomaly. The main purpose of this publication is to make the clinician aware of the oral manifestations that are seen in the patients with SWS and also to lay stress on the importance of radiographs in the diagnosis of this syndrome.

    Full Text Available Klippel Trenaunay Weber syndrome (KTWS is a rare disease characterized by hemihypertrophy, variceal enlargement of the veins, and arteriovenous (AV malformations. Renal involvement in KTWS is not known except in rare case reports. Herein, we present a case of KTWS with nephrotic syndrome. A 52-year-old male was admitted due to dyspnea and swelling of the body for the last three months. The pathological physical findings were diffuse edema, decreased lung sounds at the right basal site, increased diameter and decreased length of the left leg compared with the right one, diffuse variceal enlargements, and a few hemangiomatous lesions on the left leg. The pathological laboratory findings were hypoalbuminemia, hyperlipidemia, increased creatinine level (1.23 mg/dL, and proteinuria (7.6 g/day. Radiographic pathological findings were cystic lesions in the liver, spleen, and kidneys, splenomegaly, AV malformation on the left posterolateral thigh, and hypertrophy of the soft tissues of the proximal left leg. He was diagnosed to have KTWS with these findings. Renal biopsy was performed to determine the cause of nephrotic syndrome. The pathologic examination was consistent with focal segmental sclerosis (FSGS. He was started on oral methylprednisolone at the dosage of 1 mg/kg and began to be followedup in the nephrology outpatient clinic.

  10. Possible dendritic contribution to unimodal numerosity tuning and Weber-Fechner law-dependent numerical cognition

    Directory of Open Access Journals (Sweden)

    2009-08-01

    Full Text Available Humans and animals are known to share an ability to estimate or compare the numerosity of visual stimuli, and this ability is considered to be supported by the cortical neurons that have unimodal tuning for numerosity, referred to as the numerosity detector neurons. How such unimodal numerosity tuning is shaped through plasticity mechanisms is unknown. Here I propose a testable hypothetical mechanism based on recently revealed features of the neuronal dendrite, namely, cooperative plasticity induction and nonlinear input integration at nearby dendritic sites, on the basis of the existing proposal that individual visual stimuli are represented as similar localized activities regardless of the size or the shape in a cortical region in the dorsal visual pathway. Intriguingly, the proposed mechanism naturally explains a prominent feature of the numerosity detector neurons, namely, the broadening of the tuning curve in proportion to the preferred numerosity, which is considered to underlie the known Weber-Fechner law-dependent accuracy of numerosity estimation and comparison. The simulated tuning curves are less sharp than reality, however, and together with the evidence from human imaging studies that numerical representation is a distributed phenomenon, it may not be likely that the proposed mechanism operates by itself. Rather, the proposed mechanism might facilitate the formation of hierarchical circuitry proposed in the previous studies, which includes neurons with monotonic numerosity tuning as well as those with sharp unimodal tuning, by serving as an efficient initial condition.

    Full Text Available In this work, the response surface methodology was employed to optimize the microencapsulation of Agave tequilana Weber var. azul juice with whey protein isolated using a spray drying technique. A Box-Behnken design was used to establish optimum spray drying conditions for Agave tequilana juice. The process was optimized to obtain maximum powder yield with the best solubility time, hygroscopicity, bulk density, water activity, and reducing sugars. The independent parameters for the spray drying process were outlet temperature of 70–80°C, atomizer speed of 20000–30000 rpm, and airflow of 0.20–0.23 m3 s−1. The best spray drying condition was at outlet temperature of 80°C, atomizer speed of 20000 rpm, and air flow rate of 0.23 m3 s−1 to obtain maximum powder yield (14.65%bm, minimum solubility time (352.8 s, maximum bulk density (560 kg m−3, minimum hygroscopicity (1.9×10-7 kgwater s−1, and minimum aw (0.39. The Agave tequilana powder may be considered as an interesting source of dietary fiber used as food additive in food and nutraceutical industries.

    Full Text Available Abstract Background Pfeifer-Weber-Christian disease (PWCD is a rare inflammatory disorder of the subcutaneous fatty tissue. The diagnosis and therapy of this rare type of panniculitis is still controversial and will be discussed in this article. Case presentation We here report the rare case of a 64-year old male patient, with PWCD. The patient suffered from rheumatoid arthritis for several years, but then developed relapsing fever and recently occurring painful subcutaneous nodules predominantly at the inner part of his left upper limb with no signs of synovitis. Finally, a biopsy from one of the nodules revealed lobular panniculitis with mixed cell infiltrate, which was conformable only with PWCD, after excluding several differential diagnoses. In our patient PWCD developed despite immunosuppressive therapy with steroids and different disease modifying drugs, which the patient received to treat his underlying rheumatoid arthritis. However, when DMARD therapy was switched to Ciclosporin A the patient's symptoms resolved. Conclusion Our observation supports the hypothesis that T cells are involved in the pathogenesis of PWCD. Thus, T cell modifying drugs should be primarily used to treat patients with this rare disorder.

    Full Text Available Aim. To report a case of bilateral Sturge-Weber and Phakomatosis pigmentovascularis with secondary glaucoma in a child. Method. Case report. Results. A 4-year-old male child was referred to us for control of intraocular pressure (IOP. Sleeping IOP was 36 mm Hg in right eye and 28 mm Hg in the left eye. The sclera of both the eyes showed bluish black pigmentation—melanosis bulbi. Fundus examination of both eyes showed diffuse choroidal hemangiomas with glaucomatous cupping. Nevus flammeus was present on both sides of face along all the 3 divisions of trigeminal nerve with overlying hypertrophy of skin and on left forearm. Nevus fuscocaeruleus was present on upper trunk. All skin lesions were present since birth and were stationary in nature. CT scan of head revealed left-sided cerebral atrophy. Intraocular pressure was controlled after treatment with topical antiglaucoma medications. Pulsed Dye Laser has been advised by dermatologist for skin lesions. Patient has been advised for regular follow-up. Conclusion. The two overlapping dermatological disorders and their association with glaucoma are a rare entity. Management should be targeted both for dermatological and eye conditions.

    Full Text Available Diffuse choroidal hemangiomas associated with Sturge-Weber syndrome (SWS are classically treated with external beam radiotherapy (EBR, but there are a few reports usually of single cases indicating the usefulness of plaque therapy. We present our observations on two cases of diffuse choroidal hemangiomas with exudative retinal detachment associated with SWS treated with Ruthenium-106 plaque therapy. Outcomes included best-corrected visual acuity (BCVA and regression in tumor thickness measured by ultrasonography. The initial BCVA of the affected eyes was counting fingers at 1 meter and light projection. Pretreatment tumors thickness was 3.5 mm and 4.7 mm. In a follow-up period of 18–24 months, significant reduction in thickness of choroidal hemangiomas up to 1.2 mm and 1.4 mm with prompt resolution of exudative retinal detachment was observed. BCVA achieved 20/200 and 20/400, respectively. The findings in this paper indicate that Ruthenium-106 plaque therapy is effective in treatment of diffuse choroidal hemangiomas associated with SWS.

Naturalmente, o papel do ascetismo protestante também será considerado. Além de definir “forma” e “espírito”, os aspectos institucionais e culturais, poderemos observar que a teoria weberiana buscou compreender e explicar os fenômenos sociais em sua complexidade multicausal, sendo o capitalismo (foco aqui e o racionalismo dois dos pontos centrais de sua obra.

  17. Analysis of Epileptic Discharges from Implanted Subdural Electrodes in Patients with Sturge-Weber Syndrome.

    Full Text Available Almost two-thirds of patients with Sturge-Weber syndrome (SWS have epilepsy, and half of them require surgery for it. However, it is well known that scalp electroencephalography (EEG does not demonstrate unequivocal epileptic discharges in patients with SWS. Therefore, we analyzed interictal and ictal discharges from intracranial subdural EEG recordings in patients treated surgically for SWS to elucidate epileptogenicity in this disorder.Five intractable epileptic patients with SWS who were implanted with subdural electrodes for presurgical evaluation were enrolled in this study. We examined the following seizure parameters: seizure onset zone (SOZ, propagation speed of seizure discharges, and seizure duration by visual inspection. Additionally, power spectrogram analysis on some frequency bands at SOZ was performed from 60 s before the visually detected seizure onset using the EEG Complex Demodulation Method (CDM.We obtained 21 seizures from five patients for evaluation, and all seizures initiated from the cortex under the leptomeningeal angioma. Most of the patients presented with motionless staring and respiratory distress as seizure symptoms. The average seizure propagation speed and duration were 3.1 ± 3.6 cm/min and 19.4 ± 33.6 min, respectively. Significant power spectrogram changes at the SOZ were detected at 10-30 Hz from 15 s before seizure onset, and at 30-80 Hz from 5 s before seizure onset.In patients with SWS, seizures initiate from the cortex under the leptomeningeal angioma, and seizure propagation is slow and persists for a longer period. CDM indicated beta to low gamma-ranged seizure discharges starting from shortly before the visually detected seizure onset. Our ECoG findings indicate that ischemia is a principal mechanism underlying ictogenesis and epileptogenesis in SWS.

  18. Epileptogenesis in neurocutaneous disorders with focus in Sturge Weber syndrome [version 1; referees: 2 approved

    2016-03-01

    Full Text Available Epilepsy is a major morbidity in Sturge Weber syndrome, a segmental vascular neurocutaneous disorder classically associated with facial angiomas, glaucoma, and leptomeningeal capillary-venous type vascular malformations. The extent of the latter correlates with neurological outcome. Post-zygotic mosaicism for the activating mutation p.R183Q of the GNAQ gene has been identified as the major cause. GNAQ encodes for an alpha subunit of a heterotrimeric G protein critical to blood vessel development. The earlier the timing of the mutation in development, the more severe the involvement, e.g. from isolated port-wine stains to the full syndrome. The strongest predictors of adverse outcomes are MRI and the presence of angiomas involving any part of the forehead, delineated inferiorly from the outer canthus of the eye to the top of the ear, and including the upper eyelid.  The neurological course may be progressive and the typical constellation of symptoms is focal onset seizures, hemiparesis, headache, stroke-like episodes, behavior problems, intellectual disability, and visual field deficits. Antiseizure medications are effective in about half of patients. The presence of localized seizures, focal neurological deficits, and drug resistant epilepsy indicate epilepsy surgical evaluation. Earlier seizure onset, i.e. before six months of age, is associated with a more severe course with significant residual deficits. Factors contributing to epileptogenesis include decreased brain tissue perfusion due to abnormal venous drainage, anoxic injury contributing to cerebral calcification, breakdown of the blood-brain barrier, and the presence of developmental cortical malformations. Pre-symptomatic prophylactic treatment may be a future option to modify the course of the disease including the associated epileptogenesis.

    Joe Weber, the last child of eastern European immigrants, had a ham radio license at age 10. He also wired the mess hall of the US Naval Academy for sound, causing the chatter and clashing crockery of his fellow midshipmen to be drowned out by Schubert's Great C Major symphony. He kept a 6 cm radar (not standard equipment on submarine chasers) working before and during the Sicilian landing and ended ``his'' war in charge of electronic countermeasures for the Navy. Hired as a full professor of electrical engineering and ordered to get a PhD in something, somewhere, by the University of Maryland in 1949, he talked with George Gamow (a story for a different time), but ended up working with Keith Laidler at Catholic University of America on the inversion spectrum of ammonia, building and using a 2-meter traveling wave tube. That, plus a lecture by Karl Herzfeld on the Einstein A and B coefficients, led him to think about inverted populations as amplifiers and spectrometers. His talk at an IEEE conference and the subsequent paper were the first ``open source'' presentations of what we now call masers and lasers. Then came his interest in General Relativity and the desire to bring this beautiful theory into contact with laboratory science. He started building and then operating bar detectors for gravitational waves in 1965-66, and reporting results from 1968-69. The scientific community first took an enormous interest in his work, then ``voted him off the island'' starting in about 1973. He continued to operate bar detectors, and later perfect crystal detectors for neutrinos, until his death on 30 September 2000 (Rosh Hashonah that year). The first LIGO event was recorded on his 15th Jarhzeit. We had, by that time, been married for 28.5 years, and it was a joy to watch him pick the right resistor or capacitor out of a box of miscellaneous electronic components.

    Rendu-Osler-Weber syndrome or hereditary hemorrhagic telangiectasia is an autosomal dominant vascular disease involving multiple systems whose main pathological change is the presence of abnormal arteriovenous communications. Most common symptoms include skin and mucosal telangiectasias, epistaxis, gastrointestinal, pulmonary and intracerebral bleeding. The key imaging finding is the presence of visceral arteriovenous malformations. The diagnosis is based on clinical criteria and can be confirmed by molecular biology techniques. Treatment includes measures for management of epistaxis, as well as surgical excision, radiotherapy and embolization of arteriovenous malformations, with emphasis on endovascular treatment. The present pictorial essay includes a report of three typical cases of this entity and a literature review. (author)

    To present the case of a talocrural dislocation with a Weber type C fibular fracture in a National Collegiate Athletic Association Division I football athlete. The athlete, while attempting to make a tackle during a game, collided with an opponent, who in turn stepped on the lateral aspect of the athlete's ankle, resulting in forced ankle eversion and external rotation. On-field evaluation showed a laterally displaced talocrural dislocation. Immediate reduction was performed in the athletic training room to maintain skin integrity. Post-reduction radiographs revealed a Weber type C fibular fracture and increased medial joint clear space. A below-knee, fiberglass splint was applied to stabilize the ankle joint complex. Subtalar dislocation, Maisonneuve fracture, malleolar fracture, deltoid ligament rupture, syndesmosis disruption. The sports medicine staff immediately splinted and transported the athlete to the athletic training room to reduce the dislocation. The athlete then underwent an open reduction and internal fixation procedure to stabilize the injury: 2 syndesmosis screws and a fibular plate were placed to keep the ankle joint in an anatomically reduced position. With the guidance of the athletic training staff, the athlete underwent an accelerated physical rehabilitation protocol in an effort to return to sport as quickly and safely as possible. Most talocrural dislocations and associated Weber type C fibular fractures are due to motor vehicle accidents or falls. We are the first to describe this injury in a Division I football player and to present a general rehabilitation protocol for a high-level athlete. Sports medicine practitioners must recognize that this injury can occur in the athletic environment. Prompt reduction, early surgical intervention, sufficient resources, and an accelerated rehabilitation protocol all contributed to a successful outcome in the patient.

    Max Weber,a German social thinker,was also an important cultural theorist.In the research of the origin of the capitalist spirit,Max Weber broadened the relationship between culture and economy deeply; as a result, his theory is parallel to Marxism to some degree. In the interpretation of the western world outlook about “disenchantment,”Weber revealed the competition and conflicts in the modern value outlook,and presented a complex entanglement about the “excessive order”and “excessive conflict”in modern culture.In the research of the western rational fate,Weber analyzed the relationships between formation and technology in western self-discipline art and progress in art.All of his important theories and views not only givea new interpretation of modern cultural production but also have an important influence on the contemporary cultural theory.So this paper generalizes Weber’s cultural viewsfrom three aspects,providing some new resources for the cultural issues being discussed.%德国社会思想家马克斯·韦伯实际上也是一位重要的文化理论家。在对资本主义精神起源的研究中,韦伯深度展开探讨了文化与经济之间的关系,其所论可以与马克思主义对话;在对西方世界观“除魅”的阐释中,韦伯揭示了现代价值观的竞争和冲突,呈现了现代文化“秩序过度”与“冲突过度”的复杂纠缠;在对西方理性化命运的探究中,韦伯分析了西方自律艺术的形成及技术与艺术进步的关系。这些重要观念,不但对现代文化生产提出了新的解释,而且对当代文化理论产生了重要影响。文章从三个方面概括韦伯的文化观点,为当前正在讨论的一些文化议题提供一些新的资源。

    Abstract Phakomatosis pigmentovascularis (PPV) is a rare congenital malformation syndrome that is characterized by a combination of capillary abnormalities and dermal melanocytosis. We describe 3 cases of PPV combined with bilateral Sturge–Weber syndrome (SWS), Ota nevus, and congenital glaucoma. Case 1 was a 2-year-old boy. Facial port-wine stains distributed along the 3 branches of his trigeminal nerves, which suggested the existence of SWS. Gray-blue patches were spread over the frontal and temporal areas of bilateral face, waist, buttocks, and thigh. Bilateral triangular alopecia was found on the temporal scalp. The diagnosis of Ota nevus was made by the bilateral scleral malanocystosis. Increased intraocular pressure, enlarged cornea, and pathologic optic disc cupping supported the diagnoses of infantile bilateral glaucoma. Case 2 was a 4-year-old boy. Port-wine stains were found on the face along the 3 branches of the trigeminal nerve and distributed along the trunk, arms, and legs. Mongolian spots spread over his frontal and temporal areas of the bilateral face, waist, buttocks, thigh, abdomen, and back. Infantile glaucoma was found in both eyes. Ota nevus were found in the both eyes. Optic coherent tomography (OCT) scans revealed increased thickness of choroid. Case 3 was a 5-year-old boy. Besides Ota nevus and infantile glaucoma in both eyes, color Doppler ultrasonography showed choroidal hemagioma. OCT scan showed increased choroidal thickness. The bilateral triangular alopecia on the child's temporal scalp was similar to that of Case 1. Cases 1 and 2 presented with port-wine stain patches that were consistent with the characteristic manifestation of PPV type IIb. However, the CMTC of Case 3 met the diagnostic criteria for PPV type Vb. Case 1 was treated with trabeculotomies in both eyes. For Cases 2 and 3, surgical interventions were not considered due to the high risks of antiglaucomatous operation complications. We prescribed them antiglaucoma

    A case of left occipital leptomeningeal angiomatosis was reported. The patient was a 12-year-old boy who had episodes of severe vascular type headache accompanied by transient right homonymous hemianopsia. CT scan showed localized superficial high density area in the left occipital pole. Remarkable enhancement of the lower and inner surface of the left occipital lobe was demonstrated. Angiography showed poor filling of the distal portion of the left posterior cerebral artery. Skull tomograms showed linear calcifications in the left occipital region. Brain scan showed increased RI uptake in the left occipital region. During operation, the surface of the left occipital lobe was covered by excessive, fine, vascular networks which extended over the arachnoid membrane. The abnormal vessels were cauterized by a CO/sub 2/ laser as throughly as possible. The occipital pole felt gritty. Histologically, the abnormal vessels had spread into the subarachnoid space and were predominantly veins with thin and enlarged walls. The abnormal vessels followed the leptomeninges in the sulci of the cerebral cortex. Underneath the abnormal vessels, in the external layers of the cerebral cortex, calcium deposits were scattered and gliosis and degeneration of the ganglion cells were observed. The lesion was comparable with leptomeningeal angiomatosis. Though the pathological findings of the specimen, CT findings, and brain scan findings were extremely similar to those of Sturge-Weber disease, in this case, the typical clinical and roentgenographic findings of Sturge-Weber disease were all absent.

    The purpose of this study was to examine the genetic linkage (but not the association) between HLA complex and Weber-Cockayne Subtype of epidermolysis bullosa (EBS-WC). We HLA typed 44 members of three multi-generation families in which 24 members have the clinical evidence of EBS-WC. The patterns of inheritance of various HLA haplotypes and the disease were mathematically analyzed to estimate frequency of recombination (i.e. genetic distance) between HLA complex and the disease by calculating Lod Scores for each family separately as well as all for three families combined. Our results show that only one family had a positive Lod Score. The Lod Scores for the remaining two families as well as the combined Lod Score for all three families were negative. These data suggest that odds are against the genetic linkage between HLA complex and Weber-Cockayne Subtype of epidermolysis bullosa and in favor of independent assortment of the disease and HLA complex.

  15. High fidelity simulation and analysis of liquid jet atomization in a gaseous crossflow at intermediate Weber numbers

    Recent advances in numerical methods coupled with the substantial enhancements in computing power and the advent of high performance computing have presented first principle, high fidelity simulation as a viable tool in the prediction and analysis of spray atomization processes. The credibility and potential impact of such simulations, however, has been hampered by the relative absence of detailed validation against experimental evidence. The numerical stability and accuracy challenges arising from the need to simulate the high liquid-gas density ratio across the sharp interfaces encountered in these flows are key reasons for this. In this work we challenge this status quo by presenting a numerical model able to deal with these challenges, employing it in simulations of liquid jet in crossflow atomization and performing extensive validation of its results against a carefully executed experiment with detailed measurements in the atomization region. We then proceed to the detailed analysis of the flow physics. The computational model employs the coupled level set and volume of fluid approach to directly capture the spatiotemporal evolution of the liquid-gas interface and the sharp-interface ghost fluid method to stably handle high liquid-air density ratio. Adaptive mesh refinement and Lagrangian droplet models are shown to be viable options for computational cost reduction. Moreover, high performance computing is leveraged to manage the computational cost. The experiment selected for validation eliminates the impact of inlet liquid and gas turbulence and focuses on the impact of the crossflow aerodynamic forces on the atomization physics. Validation is demonstrated by comparing column surface wavelengths, deformation, breakup locations, column trajectories and droplet sizes, velocities, and mass rates for a range of intermediate Weber numbers. Analysis of the physics is performed in terms of the instability and breakup characteristics and the features of downstream

    Infants with Sturge-Weber syndrome (SWS) are considered for surgery if they develop seizures and the seizures prove medically refractory. The authors report on 2 infants (15 and 19 months old) with SWS who underwent scalp video electroencephalography (EEG) and subsequent functional hemispherotomy for intractable partial motor seizures due to extensive left hemispheric angiomatosis. They presented with similar interictal and ictal EEG findings. Ictal EEG showed abrupt high-amplitude delta slow waves, without evolution on the contralateral hemisphere before the build-up of ictal EEG changes on the lesional hemisphere. The patients became seizure free after hemispherotomy. The ictal contralateral slow waves were not a sign of an ictal hemisphere and may indicate prominent ischemic changes resulting from a steal phenomenon of hemispheric angiomatosis during seizure.

    Lutein epoxide has been isolated from petals of dandelion (Taraxacum officinale F. Weber ex Wiggers) by thin-layer chromatography (TLC) on silica to be used for the accurate identification of this carotenoid in other sources. The extract was analyzed by high-performance liquid chromatography (HPLC) using a C(30) column, as a result of which six geometrical isomers were separated. The identification of these isomers was performed on the basis of their UV/vis spectroscopic features in the mobile phase. In quantitative terms, it was observed that all-E-lutein epoxide was the major carotenoid and that there were also high amounts of the (9Z)- and (9'Z)-isomers, although the latter may be an artifact.

    Full Text Available ABSTRACT: Sturge Weber syndrome (SWS also called encephalo-t rigeminal-angiomatosis, is an uncommon entity in India. The characteristic featur e of SWS is the presence of “port-wine stain” varying from light pink to deep purple, covering tr igeminal nerve distribution. Patients have associated ocular involvement, mental retardation, and seizures due to the involvement of the vasculature of eye and the CNS. Neuro-ophthalmological monitoring of patients with SWS may be useful for early detection of ocular involvement before the appearance of seri ous visual complications. We have reported an unusual case of SWS with port wine stain on half of the body, retinal detachment with raised IOP and cerebellar calcifications with no neurological symptomatic manifestations.

    Full Text Available This paper examines two diverse and confronted receptions of Max Weber’s thought in the Hispanic world which we have described as “conservative” and “liberal” lines of interpretation. This analytical scheme allows us to group and highlight some of the most distinguished Spanish intellectuals whose work was influenced by Max Weber’s thought. We will review the context and the particular mode in which these intellectuals assimilated the German author’s work, the meaning of their interpretations and their labour of translation. In short, we will focus on the works of some renowned Hispanic philosophers, jurists and sociologists belonging to the “first interpretative generation” at work from the 1920’s to the 1940’s.Este artículo examina una doble y contrapuesta línea de recepción del pensamiento de Max Weber en el mundo hispanoparlante, que hemos denominado línea “conservadora” y línea “liberal”.

Revisamos el contexto, el sentido de la recepción, la labor de traducción y el modo peculiar en que asimilaron el trabajo del autor alemán. Nos centramos, en suma, en la obra de algunos renombrados filósofos, juristas y sociólogos de habla hispana, si bien limitamos nuestro análisis a la “primera generación receptora”, que fechamos en las décadas de los años 20 a los 40 del siglo XX.

    Full Text Available In 1904/05 the first edition of Weber’s Protestant Ethics was issued, where the thematic framing is ‘uncertain’ and not yet completed: religion is linked to a certain kind of ethos (of the economic system and of ethic (rational, the ethic of «ascetic Protestantism». Around the same years, Sombart outlines the expository path contained in Modern Capitalism, a detailed «picture of the general economic development», which seems to be a ‘more serious’ work – for its content and set of problems – when compared to the research conducted by his friend and colleague Max Weber. Both scholars view the question of the rise and development of capitalism as a rhythmic research: from the historic origins of the phenomenon, to the elaboration, synthesis and change of the economic process that becomes an autonomous and corrosive force in the modern stage. In the Sombartian discourse, however, the particular ‘attitude’ of the Protestant ethic as analysed by Weber can be regarded at most as one of the possible forms of heresy that justifies a certain approach (moral/punitive to money – and not as the only movement which has roused and regulated the economic or capitalistic processes in the strict meaning of economic surplus, profitable and to be reinvested following entrepreneurial logics. Whereas, what the two sociologists have in common is not only the use of sources (almost identical, but the very concept of Geist and individual predisposition of the subjects who accept the modes of action of this ordering spirit that gives an ethical/psychological boost to men endowed with charisma or with particular energy.

    Full Text Available Introduction: Klippel-Trenaunay-Weber syndrome is a rare congenital anomaly whose etiology has not yet been elucidated. It is characterized by the triad of vascular malformations, cutaneous hemangiomas and overgrowth of bone and soft tissue adjacent. Pain is a common symptom and can be triggered in the following situations: venous disease, scoliosis by the different members and hemangiomas that affect the body surface, the deep planes or viscera. Case report: A female patient, 17, sent from the SARAH Hospital - Fortaleza to the Institute of Clinic Pain José Frota diagnosed with cerebral palsy type triplegia on right eye and anophthalmia featuring an expansive process of vascular origin extending to the paraspinal region, surpassing sciatic foramen and affecting posterior muscles of the left thigh and leg. There are signs of involvement of the sciatic nerve and deep femoral vessels. He was diagnosed with Klippel-Trenaunay-Weber syndrome. She had continuous pain in shock and burning, EVA 10, extending from the lower back, groin and left leg region. The source of hospital treatment consisted of gabapentin 180mg 12/12h, codeine 10mg 12/12h, ibuprofen 300mg 12/12h, codeine/paracetamol 30mg 12/12h and morphine oral 10mg while in pain, but without pain relief. She also used paroxetine 20mg daily, due to depression. The painful condition prevented sleep, caused irritation and worsened the quality of life of the patient.

It proposes a reading of their works attending to the place these authors occupy in what, following Bruno Latour, may be named as “Modern Constitution”. From this metatheoretical level, the comparison brings to light the tools and resources of the “Modern Critique” which they utilise to build their theories of social change. From this comparative perspective, the article examines how Durkheim and Weber theorize on the “fourth guarantee” of the “Modern Constitution”, that refers to God’s presence in modernity. Finally, this “guarantee” is problematized in the frame of the contemporary society attending to current theories.

Ambos assumiram o tema central das obras de Tolstói segundo uma mesma imagem, derivada do contraste entre o mundo antigo e o moderno. Max Weber adequou esse tema a sua teoria do desencantamento do mundo e Lukács, de modo muito semelhante, seguindo seu conceito do paradoxo da necessidade religiosa.Palavras-chave: Tolstói – Weber – Lukács – Desencantamento – Necessidade Religiosa – L’Art Pour l’Art. Abstract: The tragic death in Tolstoy's writings has helped both Max Weber and György Lukács in characterizing the modern pathos as a tragic contemplation of the emptiness of life. Through Tolstoy's readings, Weber and Lukács found an interesting source of denying arts and modern sciences autonomy, considering, from the aesthetics sphere, the meaningless of this new immanent reality. Both has assumed Tolstoy main theme from the same perspective, contrasting ancient and modern worldviews. Max Weber presented this theme in his disenchantment of world theory and Lukács, in a very similar way, following the paradox of religious needing as a mainline.Keywords: Tolstoy – Weber – Lukács – Disenchantment – Religious Needing – L’Art Pour l’Art.

O erro: aplicar o conceito de “povo-pária” aos judeus da Antiguidade. Argumento de Schluchter: os historiadores mostraram que o conceito de “povo-pária” não se aplica aos judeus da Antiguidade, mas, não obstante, vale a pena insistir nesse erro porque ele conduz a um grande acerto: mostrar a importância da ruptura efetuada pelas missões Paulinas (com o particularismo judaico para o desenvolvimento do racionalismo ocidental.

    2009-07-01

    Full Text Available This article, on one hand, seeks to analyze the relationship between ethics and politics through Atom Egoyan's film, The Sweet Hereafter ; and on the other hand, it means to demonstrate that theoretical reflection on certain questions not only can and must be done through the use of written texts, but also must consider other formats, like the arts. Indeed, the film presents a problem that allows for us to pose questions that are uncomfortable for both positions traditionally opposed on the relationship between ethics and politics: for the classical one, of Aristotelian and Judeo-Christian roots, as well as the realistic one, based on Macchiavelli and Max Weber's reflections. The first one, represented in the film by the lawyer's strategy, is based on the absolute value of the truth, and thus does not seem to be able to contemplate the consequences that such a truth can entail for coexistence. The second one, characterized by some of the victims, is based on weighing the consequences of their actions, which makes them face the need to commit a lesser evil - lying on the stand in court - in order to avoid a greater evil - the fall of the community. Nonetheless, they do not seem capable of conceiving that in order to achieve political ethics, weighing the consequences is necessary but not sufficient enough, because it would oblige us to consider a political act guided by values that we consider to be wrong or bad, though defended responsibly, as ethical.

    Full Text Available The issue of legitimizing political power has specific dimensions determined by the historical context. In the period following the First World War, democratic regimes dramatically collapsed due to ample protest movements against the political establishment from different countries, but also as a result of a serious political legitimation crisis, thus making way for the rise of totalitarian regimes of Fascism and Nazism. That time debates on the problem of legitimization political power are symptomatic. Due to the general perception regarding corruption in politics and to the political incapacity to deal with social problems, we can witness a decrease of trust in contemporary democratic regimes.In order to exemplify, in a brief expositive manner, my paper will present the topic of political legitimation approached by Max Weber and Karl Jaspers, in a selection of relevant texts issued by both authors during 1919-1931. The aim of this paper is to highlight the actuality, the validity of Weber’s and Jasper’s statements and also their capacity to give pertinent responses to questions such as: What role do the common values play in the legitimating of power in a democratic society? Are there any kinds of limits regarding the electoral legitimation? How can we make the difference between a legitimate appeal and an illegitimate one, between civism and terrorism?

    Type I Sturge-Weber syndrome (SWS) is a neurocutaneous syndrome characterized by facial port wine stain and ipsilateral leptomeningeal angiomatosis. It is commonly complicated by glaucoma and neurological disturbances including seizures, hemiparesis, transient stroke-like deficits, and behavioral problems. Gadolinium-enhanced MRI is the study of choice for demonstrating the leptomeningeal angiomatosis, and is particularly useful for making the diagnosis. Cerebral hematoma and spontaneous obliteration of cerebral angiomatosis have never been reported in SWS. We describe a patient with type I SWS in which a hemorrhage in the left temporal lobe was caused by an underlying angiomatosis. No arteriovenous malformations were detected by brain CT or gadolinium-enhanced MRI, whereas a small angiomatous nidus draining into an ectasic venous collector near the hematoma was disclosed by brain CT angiography. Carotid angiography, performed 3 years after the hemorrhage, demonstrated the spontaneous obliteration of the angioma. This description expands the phenotypic spectrum of type I SWS in which the occurrence of cerebral hemorrhage and MRI-silent cerebral angiomatosis should be included, and emphasizes the need of performing a brain CT angiography in SWS patients whose routine neuroimaging studies fail to detect potentially harmful vessel malformation.

    The skull vibration-induced nystagmus test (SVINT) acts as a vestibular Weber test and reveals a vibration-induced nystagmus (VIN), elicited mainly on the vertex location, with a horizontal or torsional component beating more often toward the side of the lesion in superior canal dehiscence (SCD) than in otosclerosis (OS). In SCD, the VIN vertical component is most often up-beating. These results suggest more a global vestibular contribution than the sole stimulation of the superior semicircular canal. This study aimed to evaluate the possible occurrence of nystagmus during SVINT in unilateral conductive hearing loss related to SCD or OS. The slow-phase velocities (SPVs) of the VIN horizontal, torsional, and vertical components were recorded in patients with a unilateral otologic lesion (17 SCD, 38 OS) and 12 control subjects. Vibratory stimulations (60 Hz, 100 Hz) were applied on the vertex and on each mastoid. In SCD, VIN was observed in 82% of patients with a primarily torsional, horizontal, and vertical (up-beating) component in 40%, 30%, and 30%, respectively. Horizontal and torsional components beat toward the side of the lesion more often than in OS. Higher SPVs were observed after vertex stimulation. In OS, VIN was sparse with low amplitude and was not systematically lateralized to a specific side.

    Full Text Available Normal 0 false false false EN-MY X-NONE X-NONE The formation of immiscible liquid droplets, or slugs, in microchannels features the advantages of volume control and mixing enhancement over single-phase microflows. Although the applications of droplet-based microfluidics have been widely demonstrated, the fundamental physics governing droplet break-up remains an area of active research. This study defines an effective Weber (Weeff number that characterizes the interplay of interfacial tension, shear stress and channel pressure drop in driving slug formation in T-junction microchannel for a relative range of low, intermediate and high flow rates. The immiscible fluid system in this study consists of Tetradecane slug formation in Acetonitrile. The progressive deformation of slug interfaces during break-up events is observed. Experimental results indicate that, at a relatively low Weeff, clean slug break-up occurs at the intersection of the side and main channels. At intermediate Weeff, the connecting neck of the dispersed phase is stretched to a short and thin trail of laminar flow prior to breaking up a short distance downstream of the T-junction. At a relatively high Weeff, the connecting neck develops into a longer and thicker trail of laminar flow that breaks up further downstream of the main channel.

    The Volmer-Weber growth of high-mobility metal films is associated with the development of a complex compressive-tensile-compressive stress behavior as the film deposition proceeds through nucleation of islands, coalescence, and formation of a continuous layer. The tensile force maximum has been attributed to the end of the islands coalescence stage, based on ex situ morphological observations. However, microstructural rearrangements are likely to occur in such films during post-deposition, somewhat biasing interpretations solely based on ex situ analysis. Here, by combining two simultaneous in situ and real-time optical sensing techniques, based on surface differential reflectance spectroscopy (SDRS) and change in wafer curvature probed by multibeam optical stress sensor (MOSS), we provide direct evidence that film continuity does coincide with tensile stress maximum during sputter deposition of a series of metal (Ag, Au, and Pd) films on amorphous SiOx. Stress relaxation after growth interruption was testified from MOSS, whose magnitude scaled with adatom mobility, while no change in SDRS signal could be revealed, ruling out possible changes of the surface roughness at the micron scale.

    Taraxacum officinale Weber (dandelion) is a very ubiquitous species, and it can grow in urban environments on metal-polluted sediments deposited in the gutters. This study represents a preliminary step to verify the presence of metals in sediments collected in urban streets in Pisa and to assess the alteration in dandelion metabolites in order to understand its adaptation to polluted environments. The soil and sediments were collected at three urban streets and analyzed for total and extractable Cr, Pb, Cu, Ni, and Zn. The total values of Pb and Zn in street sediments exceeded the limits for residential areas of soils. Zn was the most mobile of the metals analyzed. Floating cultivations trials were set up with dandelion seedlings and street sediments. The metals were analyzed in roots and leaves. Antioxidant power, anthocyanins, polyphenols, non-protein thiols (NP-TH) and chlorophylls were measured in dandelion leaves. The first two parameters (anthocyanins and antioxidant power) were higher in the polluted samples compared to the control; chlorophyll content was lower in the treated samples, whereas NP-TH showed no differences. NP-TH groups determined in roots were associated with the root content of Zn and Pb. These results indicate that dandelion can tolerate plant stress by altering its metabolite content.

    Waste bagasse of Agave tequilana-Weber fibers treated with sodium hydroxide was used to elaborate hydrogel films. The bagasse was offered in an alternative use for the preparation of hydrogel films by phase inversion method without crosslinking and further purification of cellulose. The effect on the properties of the obtained films was studied when the chemical treatment of the agave fibers was changed. It was found that the resultant hydrogels showed increment in tensile from 40 N/mm(2) to 56 N/mm(2) with the increase of sodium hypochlorite concentration from 1 to 10 vol.%, respectively. With regard to biocompatibility properties of the hydrogel films, platelet adhesion, clotting time and protein adsorption were investigated. Analysis of the morphology of adherent NIH3T3 fibroblast indicated that the projected cell area, aspect ratio and long axis gradually increased with the increment of sodium hypochlorite content in the agave treatment. It was presented that the chemical treatment affects cell adhesion and morphology and lignin content remains in the brown fibers.

    Genetic variation in three forms of asexually propagated Agave tequilana Weber var. 'Azul' plants namely offsets, bulbils and in vitro cultured individuals was studied by AFLP analysis. Low levels of variation were observed between mother plants and offsets and a higher level between mother plant and bulbils. Families obtained from commercial plantations showed lower levels of variation in comparison to families grown as ornamentals. No variation was observed between the original explant and four generations of in vitro cultured plants. Epigenetic variation was also studied by analyzing changes in methylation patterns between mother plants and offspring in each form of asexual reproduction. Offsets and bulbils showed an overall decrease in methylation whereas in vitro cultured plants showed patterns specific to each generation: Generations 1 and 4 showed overall demethylation whereas Generations 2 and 3 showed increased methylation. Analysis of ESTs associated with transposable elements revealed higher proportions of ESTs from Ty1-copia-like, Gypsy and CACTA transposable elements in cDNA libraries obtained from pluripotent tissue suggesting a possible correlation between methylation patterns, expression of transposable element associated genes and somaclonal variation.

    2017-01-01

    Full Text Available The continuous planar facility location problem with the connected region of feasible solutions bounded by arcs is a particular case of the constrained Weber problem. This problem is a continuous optimization problem which has a nonconvex feasible set of constraints. This paper suggests appropriate modifications of four metaheuristic algorithms which are defined with the aim of solving this type of nonconvex optimization problems. Also, a comparison of these algorithms to each other as well as to the heuristic algorithm is presented. The artificial bee colony algorithm, firefly algorithm, and their recently proposed improved versions for constrained optimization are appropriately modified and applied to the case study. The heuristic algorithm based on modified Weiszfeld procedure is also implemented for the purpose of comparison with the metaheuristic approaches. Obtained numerical results show that metaheuristic algorithms can be successfully applied to solve the instances of this problem of up to 500 constraints. Among these four algorithms, the improved version of artificial bee algorithm is the most efficient with respect to the quality of the solution, robustness, and the computational efficiency.

    Sturge-Weber syndrome (SWS) is a congenital disorder characterized by a vascular birthmark and neurological abnormalities. Typical imaging findings using MRI or CT are superficial cerebral calcification, atrophy and leptomeningeal enhancement. We present a neonate diagnosed with SWS because of a port-wine stain. In the absence of neurological symptoms the first MRI was performed when he was 4 months old, and follow-up MRI studies were performed after his first seizure at the age of 12 months. MRI was performed using standard sequences before and after administration of IV gadolinium. A high-resolution T2*-weighted, rf-spoiled 3D gradient-echo sequence with first-order flow compensation in all three directions was used for additional venographic imaging [blood-oxygen-level-dependent (BOLD) venography]. The initial conventional MRI sequences did not demonstrate any abnormality, but BOLD venography identified leptomeningeal internal veins. Follow-up MRI after the first onset of seizures demonstrated strong leptomeningeal enhancement, while BOLD venography revealed pathological medullary and subependymal veins as well as deep venous structures. At this time there were the first signs of atrophy and CT showed marginal calcifications. This report demonstrates that high-resolution BOLD MR venography allows early diagnosis of venous anomalies in SWS, making early therapeutic intervention possible. (orig.)

Estos parámetros se emplearán en el diseño de una cosechadora- troceadora de agave. El estudio se realizó en noviembre de 2010 en la comunidad "El Copal", municipio de Irapuato, Guanajuato, México. Para cuantificar la energía unitaria se evaluaron dos parámetros. El primer parámetro fue la energía que requiere el corte de la hoja de agave, dicha energía se evaluó en 10 posiciones a lo largo de una hoja de aproximadamente 1 m, realizando 4 repeticiones. Para esto se empleó un dispositivo que aplica caída libre. El segundo parámetro fue el área de la sección transversal, en las mismas posiciones de hoja donde se determinó la energía de corte, para lo cual se empleó visión artificial. De esta información se calculó la energía unitaria, resultando un valor promedio de 2.50 J-cnr². Las propiedades físicas evaluadas presentan una gran variabilidad. La media de los resultados obtenidos concuerda con lo obtenido por otros autores(as. Se encontró que existe una relación bien definida entre: energía de corte, área de la sección transversal de la hoja y la posición de la sección a lo largo de la hoja, a medida que una de las variables aumenta la otra incrementa de acuerdo a un polinomio de segundo orden.In this study some physical properties (dimensions and weights of Agave tequilana Weber plant were determined and of their individual elements (pineapple, leaves and root using basic measuring devices, as well it was measured unitary energy required for leaves cut.

    Full Text Available La problematización de la comunidad es omnipresente en la contemporaneidad. Tanto en la forma de artefactos construidos "desde arriba" por la programática estatal, como en la forma de agrupamientos identitarios conformados "desde abajo", proliferan por doquier las referencias comunitarias. Pero no es la primera vez que esto sucede: también a finales del siglo XIX y comienzos del XX la problemática de la comunidad estaba al orden del día en la agenda político-intelectual. De maneras diversas, los sociólogos clásicos intentaron dar cuenta de ella. Este texto pondrá el foco en el pensamiento de Max Weber. Allí, no sólo se verá una concepción de la comunidad entendida como antecedente histórico de la sociedad moderna (rasgo que justamente las historias de la sociología suelen enfatizar en mayor medida, sino también otras dos nociones de la comunidad: en una, ella aparece como concepto sociológico fundamental, como un tipo ideal abstracto y general de relaciones sociales; en la otra, la comunidad adquiere un carácter político-utópico de primer rango, y es el nombre que se le pone a aquellos acontecimientos que quizás puedan recalentar el lazo social en un contexto societal signado por la racionalización y el desencanto. De la mano de este análisis, se espera encontrar en aquellas viejas elaboraciones weberianas alguna inspiración para comprender los perfiles de estas variadas configuraciones comunitarias del presente.

    Even though the inkjet technology has been recognized as one of the most promising technologies for electronic and bio industries, the full understanding of the dynamics of an inkjet droplet at its operating conditions is still lacking. In this study, the normal impact of water droplets on solid substrates was investigated experimentally. The size of water droplets studied here was 46 microm and was much smaller than the most of the previous studies on drop impact. The Weber number (We) and Reynolds number (Re) were 0.05-2 and 10-100, respectively, and the Ohnesorge number was fixed at 0.017. The wettability of the solid substrate was varied by adsorbing a self-assembled monolayer of octadecyltrichlorosilane followed by the exposure to UV-ozone plasma. The impact scenarios for low We impacts were found to be qualitatively different from the high to moderate We impacts. Neither the development of a thin film and lamella under the traveling sphere nor the entrapment of small bubbles was observed. The dynamics of droplet impact at the conditions studied here is found to proceed under the combined influences of inertia, surface tension, and viscosity without being dominated by one specific mechanism. The maximum spreading factor (beta), the ratio of the diameter of the wetted surface and the drop diameter before impact, was correlated well with the relationship ln beta=0.090 ln We/(fs-cos theta)+0.151 for three decades of We/(fs-cos theta), where theta is the equilibrium contact angle, and fs is the ratio between the surface areas contacting the air and the solid substrate. The result implies that the final shape of the droplet is determined by the surface phenomenon rather than fluid mechanical effects.

  11. Significant variations in Weber fraction for changes in inter-onset interval of a click train over the range of intervals between 5 and 300 ms.

    It is a common psychophysical experience that a train of clicks faster than ca. 30/s is heard as one steady sound, whereas temporal patterns occurring on a slower time scale are perceptually resolved as individual auditory events. This phenomenon suggests the existence of two different neural mechanisms for processing of auditory sequences with fast and slow repetition rates. To test this hypothesis we used Weber's law, which is known to be valid for perception of time intervals. Discrimination thresholds and Weber fractions (WFs) for 12 base inter-click intervals (ICIs) between 5 and 300 ms were measured from 10 normal hearing subjects by using an "up-down staircase" algorithm. The mean WF, which is supposed to be constant for any perceptual mechanism according to Weber's law, displayed significant variation with click rate. WFs decreased sharply from an average value of around 5% at repetition rates below 20 Hz to about 0.5% at rates above 67 Hz. Parallel to this steep transition, subjects reported that at rates below 20 Hz they perceived periodicity as a fast tapping rhythm, whereas at rates above 50 Hz the perceived quality was a pitch. Such a dramatic change in WF indicated the existence of two separate mechanisms for processing the click rate for long and short ICIs, based on temporal and spectral features, respectively. A range of rates between 20 and 33 Hz, in which the rate discrimination threshold was maximum, appears to be a region where both of the presumed time and pitch mechanisms are relatively insensitive to rate alterations. Based on this finding, we speculate that the interval-based perception mechanism ceases to function at around 20 Hz and the spectrum-based mechanism takes over at around 33 Hz; leaving a transitional gap in between, where neither of the two mechanisms is as sensitive. Another notable finding was a significant drop in WF for ICI = 100 ms, suggesting a connection of time perception to the electroencephalography alpha rhythm.

    The self-practice in a modern society--that is, how to fulfill “self”, “personality” or “individuality”--not only has to face the oppression and control of the outside, objective world, but also has to face subjective, spiritual emptiness and lacking support after the death of religion. This is a common dilemma that both Simmel and Weber faced. The difference between Simmel and Weber lies in that Simmel, via his life philosophy, lodged the values that led individuals in modern society to holding their self-practice and fulfillment of their unique characteristics in their innovative and living lives of essence. In contrast, Weber hoped, in a sense, to revive puritans' conception of “vocation” so as to lead individuals to dedicate themselves to a particular undertaking to fulfill their “personality”.

Rev. E 91, 023305 (2015)PLEEE81539-375510.1103/PhysRevE.91.023305]. Here, a third-order Chapman-Enskog analysis is used to extend this result from the single-relaxation-time collision operator, to a multiple-relaxation-time cascaded collision operator, whose additional relaxation rates allow a significant increase in stability. Numerical results confirm that the proposed scheme enables almost independent control of density ratio, surface tension, interface width, viscosity, and the additional relaxation rates of the cascaded collision operator. This allows simulation of large density ratio flows at simultaneously high Reynolds and Weber numbers, which is demonstrated through binary collisions of water droplets in air (with density ratio up to 1000, Reynolds number 6200 and Weber number 440). This model represents a significant improvement in multiphase flow simulation by the pseudopotential lattice Boltzmann method in which real-world parameters are finally achievable.

    Full Text Available Em 1946, Guerreiro Ramos publica a resenha "A sociologia de Max Weber - sua importância para a teoria e a prática da administração", na Revista do Serviço Público - RSP. Nela, mais do que apresentar ao leitor a obra de Weber Economia e sociedade, com foco em sua metodologia, também procura demonstrar sua aplicabilidade no trato das questões da administração pública e sua relevância num país "culturalmente colonial" como o Brasil. A considerar as especificidades da produção de conhecimento no campo de estudos organizacionais e o fato de Guerreiro Ramos expressar, no ensaio, uma visão que não é a que prevaleceu no campo, mas que é fiel à sociologia compreensiva e à metodologia ideal-típica, cabe aqui o esforço de reiterar o referido trabalho de Guerreiro Ramos a partir da proposição de uma discussão de caráter teórico conceitual com base no conteúdo resenhado relacionado à construção metodológica da crítica ideal-típica.

    Full Text Available The phakomatoses have been traditionally defined as a group of hereditary diseases with variable expressivity characterized by multisystem tumors with possible malignant transformation. The Sturge-Weber syndrome, Klippel-Trenaunay syndrome, and the phakomatosis pigmentovascularis have the facial port-wine stain in common. Numerous pathophysiogenetic mechanisms have been suggested such as venous dysplasia of the emissary veins in the intracranial circulation, neural crest alterations leading to alterations of autonomic perivascular nerves, mutation of the GNAO gene in the Sturge-Weber syndrome, PIK3CA mutation in malformative/overgrowth syndromes such as the Klippel-Trenaunay syndrome, and the twin-spotting phenomenon in phakomatosis pigmentovascularis. Other features linked to the port-wine stain and typical to all of the three conditions are glaucoma and choroidal alterations. Glaucoma can be due to malformations of the anterior chamber or high episcleral venous pressure and in phakomatosis pigmentovascularis it can also be associated with angle hyperpigmentation. The choroid can be thickened in all diseases. Furthermore, choroidal melanocytosis in the phakomatosis pigmentovascularis can lead to malignant transformation. Although the multiple pathophysiological mechanisms still require clarification, similarities in ophthalmic manifestations make it reasonable to classify these diseases in an independent group.

    Full Text Available En La situación de los trabajadores agrícolas al Este del Elba. Visión General (1892 Max Weber analiza la crisis de la comunidad de intereses que ligaba a los junkers y los aparceros para encontrar en el proyecto de formación de la nación, un antídoto contra las tendencias sociales disolventes. En Capitalismo y comunidad de trabajo (1938 François Perroux intenta conjurar la cuestión social y transformar el Estado, inyectando al mercado una dimensión comunitaria. Ambos autores problematizaron la misma falta de organización del trabajo, de un orden que, al vincular a trabajadores y capitalistas en sentidos, prácticas y relaciones comunes restringiera las posibilidades de conflicto. Este artículo circunscribe la respuesta común que Weber y Perroux ofrecieron frente a ese problema, esto es, la cuestión de la comunidad. Así, en los sucesivos apartados se discuten las características y las funciones atribuidas a la comunidad; su relación con el individuo y el papel conferido a la comunidad nacional organizada por el Estado, para plantear, finalmente, algunas conclusiones.

    Full Text Available A importância do trabalho do sociólogo Max Weber é inegável na história das Ciências Sociais, mas será que a partir de sua obra, intitulada A ética protestante e o espírito do capitalismo, é possível explicar o consumo de luxo atual? Neste artigo, serão apresentadas algumas críticas feitas ao livro por estudiosos que acreditam que o seu autor tenha desprezado fatos importantes que influenciaram a sociedade no século XVII, tais como a moda, a valorização do amor romântico e a mentalidade européia de modo geral. Campbell, por exemplo, afirma que esse recorte histórico faz com que Weber não leve em consideração mudanças sociais importantes. Se na época em que foi escrito, o livro já não era suficiente para explicar o consumo de luxo, tal fato se torna mais evidente na atualidade, em que o ascetismo já não predomina nas sociedades ocidentais, e até países em desenvolvimento se renderam ao consumo de artigos de luxo.

    Full Text Available CONTEXTO: A síndrome de Klippel-Trénaunay-Weber é uma doença rara sobre a qual encontramos poucos artigos na literatura (geralmente relatos de casos esporádicos relacionados a complicações. OBJETIVO: Avaliar o perfil epidemiológico dos portadores da referida síndrome. MÉTODOS: Foram copilados dados dos prontuários de 58 pacientes acompanhados no ambulatório de doenças linfáticas e angiodisplasias da disciplina de Cirurgia Vascular da Faculdade de Ciências Médicas da Santa Casa de São Paulo. RESULTADOS: A distribuição foi igual entre homens e mulheres (30 homens e 28 mulheres. A idade média dos pacientes em tratamento foi de 12,8 anos. Na maioria dos casos, a doença foi diagnosticada na infância, sendo a mancha em vinho do porto o primeiro sinal notado pela família, no nascimento ou primeiro ano de vida. O sintoma mais referido foi a dor, normalmente relacionada aos sintomas de estase venosa, sendo o sintoma considerado debilitante. Pela classificação CEAP, encontramos as crianças nas classes C0 e C1 e a maioria dos adultos nas classes avançadas. Foi diagnosticada a presença de fístulas arteriovenosas em 8,5% dos casos. Apenas 6,8% referiram história familiar. CONCLUSÃO: A síndrome de Klippel-Trénaunay e a síndrome de Parkes Weber são apresentações diferentes de uma única enfermidade e podem ser estudadas conjuntamente como síndrome de Klippel-Trénaunay-Weber. O melhor momento para reconhecer os portadores e poder amenizar a progressão de insuficiência venosa, hipertrofia óssea e tecidos moles é a infância. O tratamento compressivo deve ser indicado a todos os portadores com o intuito de diminuir a evolução da doença venosa periférica.BACKGROUND: Klippel-Trenaunay-Weber syndrome is a rare disorder about which there are few articles available (most of them are sporadic case reports related to complications. OBJECTIVE: To assess the epidemiological profile of patients with Klippel-Trenaunay-Weber

    Full Text Available El problema de Weber consiste en calcular la localizaci´on ´optima de un punto de modo que sea m´ınima la suma ponderada de las distancias desde dicho punto a un conjunto de puntos dados. Este problema, que tiene su aplicacion economica en el ambito de la localizaci´on y que ha sido ampliamente tratado en la literatura cientıfica, tiene como origen una cuestion matematica formulada en el siglo XVII por Fermat. Los primeros algoritmos de resolucion, propuestos por Torricelli y Simpson, estaban basados en razonamientos puramente geometricos, aunque tambien es destacable la existencia la denominada m´aquina de Varignon, un ingenio mecanico que permite determinar el ´optimo del problema de Weber. A pesar de que estos m´etodos son citados en numerosas fuentes bibliograficas, las demostraciones de los teoremas en los que se sustentan no son tan accesibles para investigadores y docentes por tratarse de textos clasicos con varios siglos de antig¨uedad. En este trabajo, ademas de realizar una revisi´on de diversos m´etodos empleados a lo largo de la historia para resolver el problema de Weber, se presentan demostraciones basadas en argumentos geometricos y fısicos que demuestran la veracidad de estos algoritmos, ası como algunas conclusiones y deducciones sobre el problema de Weber que se extraen de los razonamientos presentados.

    Full Text Available Introducción: La Fenitoína es un fármaco antiepiléptico utilizado comúnmente en crisis focales y tónico-clónicas generalizadas. Este fármaco tiene una cinética no lineal compleja, alta unión a proteínas y una ventana terapéutica estrecha, por lo cual la intoxicación se convierte en un riesgo latente. El cuadro clínico de intoxicación por fenitoína está conformado por alteración de la función cerebelosa y vestibular, somnolencia, debilidad generalizada, visión bo­rrosa, movimientos coreo-atetósicos y coma. Caso clínico: Paciente masculino de 20 años de edad con diagnóstico de síndrome de Sturge-Weber asociado a crisis epilépticas parciales complejas tratado con 300 mg de fenitoína diaria durante tres meses, tiempo en el que presenta síntomas progresivos caracterizados por somnolencia, visión borrosa, imposibilidad para la marcha, disartria y movimientos involuntarios coreo-atetósicos que fueron interpretados como parte de su enfermedad hasta antes de su ingreso al Instituto Nacional de Ciencias Neurológicas, Lima, Perú. El paciente ingresa con un título de 75,6 ug/ml de fenitoína en plasma, por lo que se decide el retiro del fármaco y su reemplazo por fenobarbital. El cuadro clínico fue remitiendo conforme disminuían los títulos de fenitoína en el paciente. Interpretación: La evaluación de factores asociados al metabolismo y monitorización periódica de los niveles séricos de fenitoína en los pacientes que reciben este fármaco es crucial, asimismo es importante el conocimiento de síntomas que indiquen toxicidad para que no sean confundidos con manifestaciones presentes en enfermedades subyacentes como el síndrome de Sturge-Weber en este caso.

    Full Text Available Not available

    Recurso frecuente de lo que hoy reconstruimos como Ilustración fue desarbolar supersticiones y mitos. Es, sin embargo. lugar común redargüir que quien derriba ídolos no está libre de edificar otros nuevos (ni -tópico éste que cunde por doquier- de convertir su gesto iconoclasta en mito fundacional. No menos acostumbrado es apuntar a Max Weber como al primer desvelador de algún que otro episodio sobresaliente de la historia de la razón ilustrada, ya sea para abundar en su diagnóstico, ya para intentar salir de lo que se tiene por su «círculo hechizado ». En lo que sigue, se trata de rastrear algunas de las claves configuradoras de la crítica weberiana de la cultura procurando retrotraer a su desmantelamiento metodológico del ideal historicista, los términos en que elabora su problematízacíón del sujeto rnoderno. La inversión semántica de las categorías centrales de la epistemología y la Weltanschauung del historicísmo alemán decimonónico permite a Max Weber descubrir patologías del paradigma ilustrado allí donde se suele situar un momento de critica del mismo. Siguiendo los pasos de esta estrategia weberiana, nos es posible reconstruir la noción hípostasiada de racionalidad y de sujeto que Weber parece denunciar como tentación dogmática de la razón ilustrada. El programa weberiano constituye así el desenmascaramiento de un relato complaciente de lo moderno -al que llamo el «mito de la transparencia de la razóns-ey sobre ese supuesto cabe releer sus propuestas éticas más controvertidas, en particular la distinción entre «ética de convicción» y "ética de responsabílidad ».

    We report on Sb surfactant growth of InAs nanostructures on GaAs{sub 0.51}Sb{sub 0.49} layers deposited on InP (001) and on (113)B oriented substrates. On the (001) orientation, the presence of Sb significantly favors the two-dimensional growth regime. Even after the deposition of 5 mono-layers of InAs, the epitaxial film remains flat and InAs/GaAs{sub 0.51}Sb{sub 0.49} type-II quantum wells are achieved. On (113)B substrates, same growth runs resulted in formation of high density InAs islands. Microscopic studies show that wetting layer is missing on (113)B substrates, and thus, a Volmer-Weber growth mode is concluded. These different behaviors are attributed to the surface energy changes induced by Sb atoms on surface.

    Hereditary hemorrhagic telangiectasia (HHT) or Osler-Weber-Rendu disease is an autosomal dominant disorder characterized by repeated episodes of bleeding. Multiple telangiectases consisting of thin-walled, dilated vascular channels with arteriovenous communication may involve, for example, mucocutaneous tissue, the gastrointestinal tract, and the liver, lung, and brain. We report the imaging findings of two cases of HHT involving arteriovenous malformation of both the lungs and liver, a rare condition. Chest radiography revealed a round mass, while helical CT showed a feeding artery and draining vein with arteriovenous malformation in the lung. Color Doppler sonography revealed an enlarged and tortuous hepatic artery with high systolic velocity. CT demonstrated an enlarged hepatic artery, arteriovenous shunt, and early draining hepatic vein in the liver. Celiac angiography showed arteriovenous malformation.

    In 4 Sturge-Weber-syndrome child patients with calcified lesions mainly in the occipital lobe, regional cerebral blood flow (rCBF) was determined with stable Xe-CT in the resting state and after iv injection of acetazolamide (AA) and megimide (M), with the purpose of examining factors affecting deterioration of neurologic manifestations and the influence of lobectomy. In the resting state, rCBF of the temporal and occipital areas was significantly lower on the affected than unaffected sides. The side-to-side asymmetry of rCBF in the affected and unaffected sides decreased from the frontal to temporal and occipital areas. It was indistinct after AA injection because cerebral vasoreactivity became higher on the affected side. A low rCBF in association with a high cerebral vasoreactivity on the lesion side suggested that the low rCBF matched the low cerebral metabolism of the brain area affected by leptomeningeal angiomatosis. However, cerebral vasoreactivity to AA depended on clinical presentations. Two patients presented with progressive mental retardation. The other two patients were in clinically stable condition. Cerebral vasoreactivity to AA in the former two cases was poorer on both the affected and unaffected sides than that in the latter two cases. M administration was associated with a significantly decreased rCBF in the area of leptomeningeal angiomatosis and cerebral calcification and with a significantly increased rCBF of the 'pericalcified' area. In one patient undergoing extended occipital lobectomy on the affected side, no decrease in rCBF was noted in the resting state in either affected or unaffected side, and cerebral vasoreactivity to AM on the unaffected side was apparently increased. Both circulatory disturbance and seizure appear to play a role in clinical presentations, as well as their deterioration in Sturge-Weber-Syndrome patients. (N.K.).

    基于韦伯-费希纳定律基本原理,以表征水体富营养化的Chla、TP、TN、SD、CODMn的浓度作为评价指标,采用变异系数法确定各评价指标的权重,通过确定营养状态等级与综合影响指数间的函数关系,定量评价水体的富营养化程度,将该理论应用于2006年北京市21个湖泊富营养化状况的评价,并与TSIc、EI两种方法的评价结果进行比较.结果表明,韦伯-费希纳定律物理意义明确、计算过程简单、可复制性强、评价结论准确合理.%According to Weber-Fechner law, concentrations of chlorophyll-a(Chla), total phosphorus(TP), total nitrogen(TN), transparency (SD) and chemical oxygen demand(CODMn) are taken as the evaluation indicators of lake eutrophication. And the weights of each evaluation indicator are calculated with variation coefficient method. Based on the functional relationship between the trophic level and the eutrophication integrated index, the lake eutrophication is assessed quantificationally. Finally, the model is applied to assessing 21 lakes eutrophication in Beijing city and evaluation results are compared with those of TSIc and El methods. The results show that Weber-Fechner law has explicit physical significance, simple calculating process, easy for duplicating and reasonable for evaluation conclusion.

  2. Comment on the Max Weber Thought of Legitimacy%马克斯·韦伯合法性思想评析

    2011-01-01

    In the history of Western political thought, Max Weber systematic studied the question of political legitimacy for the first time and made it a classical theory. Weber~ thought of legitimacy primary concern was how the rulers to rule the people, rather than why the rulers to rule the people. Authority and obedience is a political reality and is not a value judg- ments. The basis of legitimacy can be divided into three types : following the traditional, the conviction of Charisma, and fol- lowing the reason. Only the legal - rule exemplifies the trend of historical development. It is the inevitable result of political development. Weberg theory of legitimacy is very groundbreaking, but it takes away the core of value of the normative legal theory, showing a significant technical and tool orientation.%在西方政治思想史上,马克斯·韦伯第一次对政治合法性问题进行了系统研究并使之成为经典理论。韦伯合法性关注的首要问题是统治者如何统治,而不是统治者为何统治。权威与服从,是一种政治现实,而非价值判断。合法性基础可分为三种:对传统的遵从、对超凡魅力的信服和对理性的追随。唯有法理型统治才体现了历史发展的潮流,是政治发展的必然结果。韦伯的合法性理论极富开创性,但抽去了规范主义合法性理论的价值反思内核,表现出明显的技术化、工具化倾向。

Este fármaco tiene una cinética no lineal compleja, alta unión a proteínas y una ventana terapéutica estrecha, por lo cual la intoxicación se convierte en un riesgo latente. El cuadro clínico de intoxicación por fenitoína está conformado por alteración de la función cerebelosa y vestibular, somnolencia, debilidad generalizada, visión bo- rrosa, movimientos coreo-atetósicos y coma. Caso clínico: Paciente masculino de 20 años de edad con diagnóstico de síndrome de Sturge-Weber asociado a crisis epilépticas parciales complejas tratado con 300 mg de fenitoína diaria durante tres meses, tiempo en el que presenta síntomas progresivos caracterizados por somnolencia, visión borrosa, imposibilidad para la marcha, disartria y movimientos involuntarios coreo-atetósicos que fueron interpretados como parte de su enfermedad hasta antes de su ingreso al Instituto Nacional de Ciencias Neurológicas, Lima, Perú. El paciente ingresa con un título de 75,6 ug/ml de fenitoína en plasma, por lo que se decide el retiro del fármaco y su reemplazo por fenobarbital. El cuadro clínico fue remitiendo conforme disminuían los títulos de fenitoína en el paciente. Interpretación: La evaluación de factores asociados al metabolismo y monitorización periódica de los niveles séricos de fenitoína en los pacientes que reciben este fármaco es crucial, asimismo es importante el conocimiento de síntomas que indiquen toxicidad para que no sean confundidos con manifestaciones presentes en enfermedades subyacentes como el síndrome de Sturge-Weber en este caso.

    Full Text Available Agave crop (Agave tequilana Weber is an option to produce bioethanol as biofuel. By-hand-harvesting of agave is 75 % of crop production costs, resulting in a higher production cost of bioethanol than for other crops. This paper presents a proposal of agave shredder-harvester, for which are considered: existing proposals, the methodology of current crop harvest, agricultural machines and mechanisms of interest, requirements of the raw material for bioethanol production. Agave harvester proposed considers shredding of leaves and pineapple retaking ideas of gridding mechanisms such as milling of agave, shredding crop residues machines. The mechanization of the harvest of agave for production of bioethanol presents feasibility that will require a research to design, the crushing mechanism, its blades, geometry and dimensions, and the power required to measure different elements of the combine harvester in the crushing operation, as well as other variables.El Agave tequilana Weber es una opción para la producción de bioetanol combustible.

    Full Text Available The main objective of this paper is to elucidate the very nature of ‘the rationalization of the body’ in regard to the convergence and divergences as envisioned in the works of Max Weber and Michael Foucault. While both of the thinkers may be deemed to be important critiques of the modernity process, their insights reveal certain commonalities as the came to deal with the rationalization of the body and individuation of the body along with differences that can be traced back to their roots in their critiques about the modernity project. In such respect, the study emphasizes that rationalization of the body has been a complex process and it italicizes that different dynamics came to redefine the body and individuate the individual along with the continuation of the process.

Muitas vezes esquecemos que a vida ultrapassa nossos autores, teses e paradigmas e que a linguagem que utilizamos é apenas o nosso esforço limitado para revelar tudo o que vemos diante da elaboração das ações humanas. Somente nossa imaginação é que pode reunir o que vemos, lemos e ouvimos para elaborarmos diferentes rumos para esta estrada do conhecimento. O pretenso caminho límpido da ciência é na verdade movido pela razão, mas impulsionado pela chamas da paixão, pois é através desta que o cientista delimita uma trilha a seguir, fazendo prevalecer alguns valores e rejeitando outros, sendo assim buscamos perceber como a vocação científica não se restringe somente a pôr em práticas regras estabelecidas, mas que também que precisamos estar abertos à intuição e à paixão pelo o que fazemos.

  7. Two Phase Non-Rigid Multi-Modal Image Registration Using Weber Local Descriptor-Based Similarity Metrics and Normalized Mutual Information

    Non-rigid multi-modal image registration plays an important role in medical image processing and analysis. Existing image registration methods based on similarity metrics such as mutual information (MI) and sum of squared differences (SSD) cannot achieve either high registration accuracy or high registration efficiency. To address this problem, we propose a novel two phase non-rigid multi-modal image registration method by combining Weber local descriptor (WLD) based similarity metrics with the normalized mutual information (NMI) using the diffeomorphic free-form deformation (FFD) model. The first phase aims at recovering the large deformation component using the WLD based non-local SSD (wldNSSD) or weighted structural similarity (wldWSSIM). Based on the output of the former phase, the second phase is focused on getting accurate transformation parameters related to the small deformation using the NMI. Extensive experiments on T1, T2 and PD weighted MR images demonstrate that the proposed wldNSSD-NMI or wldWSSIM-NMI method outperforms the registration methods based on the NMI, the conditional mutual information (CMI), the SSD on entropy images (ESSD) and the ESSD-NMI in terms of registration accuracy and computation efficiency.

    The ground-water resources in Ogden Valley, eastern Weber County, Utah, were the subject of a study to provide a better understanding of the hydrologic system in the valley and to estimate the hydrologic effects of future ground-water development. The study area included the drainage basin of the Ogden River upstream from Pineview Reservoir dam and the drainage basin of Wheeler Creek. Ogden Valley and the surrounding area are underlain by rocks that range in age from Precambrian to Quaternary.The consolidated rocks that transmit and yield the most water in the area surrounding Ogden Valley are the Paleozoic carbonate rocks and the Wasatch Formation of Tertiary age. Much of the recharge to the consolidated rocks is from snowmelt that infiltrates the Wasatch Formation, which underlies a large part of the study area. Discharge from the consolidated rocks is by streams, evapotranspiration, springs, subsurface outflow, and pumping from wells. Water in the consolidated rocks is a calcium bicarbonate type and has a dissolved-solids concentration of less than 250 milligrams per liter.

    The twolined chestnut borer, Agrilus bilineatus (Weber) (Coleoptera: Buprestidae), attacks oaks (Quercus spp.) and is associated with extensive mortality of trees in the eastern deciduous forests of North America. We tested the hypothesis that winter starch reserves of oak roots are an indicator of tree vigor and that only trees low in stored starch would be attacked by A. bilineatus. We measured the levels of stored starch in the roots of 200 non-infested healthy white oaks during the dormant season and determined their correlation with A. bilineatus attacks the following spring. There was a significant increase in A. bilineatus captures on sticky traps with a decrease in winter starch reserves. Trees low in stored starch that were also stressed by phloem-girdling attracted 3.7 times as many beetles as did non-girdled trees that were low in starch. However, non-girdled trees that had low winter starch reserves were also attacked. Only oaks that had had extremely low winter root starch reserves (5 mg/g dry wt died. These results indicate that winter starch reserves are a good predictor of A. bilineatus attack.

    Full Text Available O tratamento dado à tese da secularização pela sociologia empírica da religião praticada hoje no Brasil simplesmente não satisfaz (pelo menos aos intelectos teoricamente mais exigentes. Neste ensaio, diante da celebração empirista e inconseqüente de fenômenos religiosos que supostamente estariam fazendo da nossa contemporaneidade uma época de "dessecularização", ou" pós-secularização", o autor defende a necessidade de se reabrir a discussão conceitual do problema. Pode ser de grande utilidade para a sociologia da religião, argumenta, enfrentar-se de novo com o velho significado jurídico-político com o qual, no Ocidente, se pôs a questão deste processo histórico-social de dessacralização instalado, antes de mais nada, na esfera vital da normatividade jurídico-política. Este é o significado que se explicita na "sociologia do direito" de Max Weber, autor que é considerado, também por seus críticos, o maior representante da tese da secularização na teoria sociológica.

    A new species of digenean, Pseudobacciger cheneyae n. sp., is described from the intestines of Weber's chromis (Chromis weberi Fowler & Bean) from off Lizard Island, Great Barrier Reef, Australia. This species differs from the three described species of Pseudobacciger Nahhas & Cable, 1964 [P. cablei Madhavi, 1975, P. harengulae Yamaguti, 1938 and P. manteri Nahhas & Cable, 1964] in combinations of the size of the suckers and the length of the caeca. The host of the present species is a perciform (Family Pomacentridae) which contrasts with previous records of the genus which are almost exclusively from clupeiform fishes. The genus Pseudobacciger is presently recognised within the family Faustulidae (Poche, 1926) but phylogenetic analyses of 28S and ITS2 rDNA show that the new species bears no relationship to species of four other faustulid genera (Antorchis Linton, 1911, Bacciger Nicoll, 1924, Paradiscogaster Yamaguti, 1934 and Trigonocryptus Martin, 1958) but that instead it is nested within the Gymnophalloidea (Odhner, 1905) as sister to the Tandanicolidae (Johnston, 1927). This result suggests that the Faustulidae is polyphyletic.

  14. Experimental studies on the effect of Reynolds and Weber numbers on the impact forces of low-speed droplets colliding with a solid surface

    The impact force of low-speed droplets colliding with a solid surface was recorded with an experimental setup involving a highly sensitive piezoelectric force transducer and a high-speed camera recording the droplet shape. Water, ethanol, pure glycerin and aqueous glycerin solutions were used. Experimental results showed that dimensionless force is independent of the Weber number in the experimental range of 68-858 but varies with the Reynolds number. The impact is categorized into three types of processes according to the data on dimensionless peak force against the Reynolds number. The first type is a viscosity-dominated one, in which the Reynolds number ranges between 2.9 and 20. In the second type, transition process, the Reynolds number is in the range of 20-230. In the inertia-dominated type, the Reynolds number is larger than 230. In the viscosity-dominated impact, dimensionless peak force decreases rapidly with increasing Reynolds number, and the effect of viscosity could not be ignored. In the inertia-dominated impact, dimensionless peak force remains constant with varying the Reynolds number, that is, impact force is directly proportional to the product of liquid density, velocity squared and diameter squared but is unaffected by the changes in viscosity and surface tension. Furthermore, the deformation of droplet shape due to oscillation affects the impact force; a small horizontal-to-vertical ratio results in small impact force and vice versa.

    Fermentative processes are widely used to produce food, beverages and biofuels. Saccharomyces cerevisiae is an efficient ethanol-producing microorganism. However, a concentration of high ethanol and other metabolites can affect yeast viability and decrease the ethanol yield. Many studies have focused on improving the fermentative efficiency, mostly through the genetic engineering of genes that have a direct impact on specific metabolic pathways. In the present study, we characterized a small open reading frame encoding a protein with an unknown function and biological role termed YNR034W-A. We analyzed the expression profile of the YNR034W-A gene during growth and glucose treatment, finding that it is expressed during the diauxic shift and stationary phase and is negatively regulated by glucose. We overexpressed the YNR034W-A gene in the BY4741 laboratory strain and a wild-type yeast strain (AR5) isolated during the Tequila fermentation process. Transformant derivatives of the AR5 strain showed an improved fermentative efficiency during fermentation of Agave tequilana Weber juice. We suggest that the improved fermentative efficiency is the result of a higher stress tolerance response in the YNR034W-A overexpressing transformant.

Os testes mecânicos foram realizados em máquina universal de ensaios do Laboratório de Bioengenharia da Faculdade de Medicina de Ribeirão Preto, Campus Universitário, Universidade de São Paulo. Nos parâmetros analisados como limite de proporcionalidade, módulo de elasticidade observaram-se valores diferentes entre as duas placas mostrando que o novo implante apresentou resistência e estabilidade superior à placa semitubular quando submetidos a testes de flexão.The author compares this new plate with other type of fixation described by Weber that employed a semitubular plate based on tension band principle. The mecanical tests were perfomed in a universal test machine of the "Laboratório de Bioengenharia da Faculdade de Medicina de Ribeirão Preto, Campus Universitário, Universidade de São Paulo". A three-point-flexion test established was employed dislocation.The weak point in the semitubular plate model ocurred mainly where it was bent at is external hole, displaying hole enlargement at loads of less than 30 N.m. The author choosed the 3-points flexion test, which provides a qualitative indication of the material resistivity. The conclusion was that the new implant showed stability and resistance superior to the semitubular plate when submitted to flexion tests.

Las empresas medianas o grandes de carácter asociativo son parte del nuevo perfil campesino y los conocimientos y las habilidades necesarias para operarlos se están incorporando a su cultura. El campesino no es una persona o familia, el campesino es un fenómeno social, él se ubica en el contexto histórico, ético, folklórico y religioso y difícilmente puede ser definible, ni siquiera indefinible, debido a la multiplicidad de roles que cumple en la sociedad actual. El campesino actual es una mezcla de pasado, presente y futuro, esta afirmación en definitiva es la clave de su reproducción. En este sentido, tratar de entender y comprender las organizaciones campesinas a través de teorías sociológicas propuestas en el pasado, en especial el concepto de acción social de Max Weber sería poco prudente, ya que las estructuras de valores de estos individuos ha cambiado sustancialmente o de lo contrario ha desaparecido. Aunque el concepto de los valores impera, el mismo está inmerso dentro un momento histórico distinto al de Weber. La finalidad del presente ensayo es hacer una reflexión teóricaacerca de los preceptos de acción social de Weber y mostrar que los mismos no son una herramienta de análisis válida ni adecuada para entender al individuo actual, en especial al campesino.

O objetivo do presente relato foi descrever a anestesia em paciente portador dessa síndrome. RELATO DO CASO: Paciente do sexo masculino, 25 anos, submetido à correção cirúrgica de fratura de órbita esquerda. Portador da tríade epistaxe recorrente, histórico familiar e telangectasia, apresentava diagnóstico de THH. Durante a investigação pré-operatória não foram encontradas malformações vasculares pulmonares, encefálicas ou do trato gastrintestinal. O paciente foi submetido à anestesia venosa total, uma hora após a administração profilática de antifibrinolítico. O sangramento foi considerado normal para a operação proposta e não houve instabilidade hemodinâmica ou necessidade de transfusão sanguínea perioperatória. A extubação ocorreu na sala cirúrgica e o paciente foi liberado para o quarto após 60 minutos e a alta hospitalar foi após 24 horas. CONCLUSÕES: A THH é uma doença autossômica dominante que provoca displasia vascular musculocutânea e visceral. Pode haver perda sanguínea perioperatória acima da esperada para pacientes portadores dessa síndrome. Como o sangramento não é resultado de defeito na cascata de coagulação mas da exposição cirúrgica da estrutura vascular malformada, a conduta perioperatória inclui o emprego de antifibrinolíticos, a realização de hemostasia adequada e da hipotensão arterial induzida, quando não houver contra-indicação.

    The importance of leaf surface wax compounds from the rice-field weed Ludwigia octovalvis (Jacq.) Raven (Onagraceae) was determined in the flea beetle Altica cyanea (Weber) (Coleoptera: Chrysomelidae). Extraction, thin layer chromatography and GC-MS and GC-FID analyses of surface waxes of young, mature and senescent leaves revealed 20, 19 and 19 n-alkanes between n-C15 and n-C35, respectively; whereas 14, 14 and 12 free fatty acids between C12:0 and C22:0 fatty acids were identified in young, mature and senescent leaves, respectively. Tricosane was predominant n-alkane in young and mature leaves, whilst eicosane predominated in senescent leaves. Heneicosanoic acid, palmitic acid and docosanoic acid were the most abundant free fatty acids in young, mature and senescent leaves, respectively. A. cyanea females showed attraction to 0.25 mature leaf equivalent surface waxes compared with young or senescent leaves in a short glass Y-tube olfactometer bioassay. The insects were attracted to a synthetic blend of 0.90, 1.86, 1.83, 1.95, 0.50 and 0.18 µg ml-1 petroleum ether of hexadecane, octadecane, eicosane, tricosane, palmitic acid and alpha-linolenic acid, respectively, comparable with the proportions as present in 0.25 mature leaf equivalent surface waxes. A. cyanea also laid eggs on a filter paper moistened with 0.25 mature leaf equivalent surface waxes or a synthetic blend of 0.90, 1.86, 1.83, 1.95, 0.50 and 0.18 µg ml-1 petroleum ether of hexadecane, octadecane, eicosane, tricosane, palmitic acid and alpha-linolenic acid, respectively.

    The twolined chestnut borer, Agrilus bilineatus (Weber) (Coleoptera: Buprestidae), attacks stressed oaks (Quercus spp.) and is associated with extensive mortality of trees in the eastern deciduous forests of North America. We examined host location by the insect and subsequent host mortality in experimentally stressed trees. A. bilineatus adults were able to rapidly and specifically locate stressed oak trees. Up to 160 beetles per week were captured on sticky band traps on the trunks of stressed trees, while beetles rarely landed on unstressed control trees. This suggests that adult borers have an acute perception of host tree "quality", and that this perception is from a distance. One mechanism of host location may be detection of volatile compounds produced by stressed trees.The condition of the host tree appears to regulate both beetle attraction and successful colonization. Mortally wounded (xylem-girdled) trees attracted beetles only until the cambium died. Xylem-girdled trees were attacked early in the beetle flight season, but larvae did not survive to emerge as adults from these trees. In contrast, phloemgirdled trees continued to attract beetles throughout the flight period. Phloem-girdled trees which were heavily attacked by A. bilineatus died late in the season in which they were attacked. Lightly attacked trees survived until the following growing season, and were then heavily attacked and killed. In one stand, phloem-girdled trees were not attacked, healed over the girdling wounds and were still alive three years after girdling. These results indicate that oak trees are only attractive to A. bilineatus within a narrow range of physiological conditions following stress but prior to mortality. A. bilineatus appears to be a proximate agent of mortality in stressed oaks in eastern North America.

    We present a method to evaluate and integrate paleoseismic data from multiple sites into a single, objective measure of earthquake timing and recurrence on discrete segments of active faults. We apply this method to the Weber segment (WS) of the Wasatch fault zone using data from four fault-trench studies completed between 1981 and 2009. After systematically reevaluating the stratigraphic and chronologic data from each trench site, we constructed time-stratigraphic OxCal models that yield site probability density functions (PDFs) of the times of individual earthquakes. We next qualitatively correlated the site PDFs into a segment-wide earthquake chronology, which is supported by overlapping site PDFs, large per-event displacements, and prominent segment boundaries. For each segment-wide earthquake, we computed the product of the site PDF probabilities in common time bins, which emphasizes the overlap in the site earthquake times, and gives more weight to the narrowest, best-defined PDFs. The product method yields smaller earthquake-timing uncertainties compared to taking the mean of the site PDFs, but is best suited to earthquakes constrained by broad, overlapping site PDFs. We calculated segment-wide earthquake recurrence intervals and uncertainties using a Monte Carlo model. Five surface-faulting earthquakes occurred on the WS at about 5.9, 4.5, 3.1, 1.1, and 0.6 ka. With the exception of the 1.1-ka event, we used the product method to define the earthquake times. The revised WS chronology yields a mean recurrence interval of 1.3 kyr (0.7–1.9-kyr estimated two-sigma [2δ] range based on interevent recurrence). These data help clarify the paleoearthquake history of the WS, including the important question of the timing and rupture extent of the most recent earthquake, and are essential to the improvement of earthquake-probability assessments for the Wasatch Front region.

    Betalains, which are red-purple and yellow pigments, are ideal alternatives to synthetic colorants as they possess strong coloring potential and excellent health-contributing properties. However, the instability of betalains toward normal storage and biological conditions, in addition to the limited number of betalain sources, impedes their food application and diminishes their bioactivities. This study aimed to evaluate the health-promoting bioactivities of betalains from red dragon fruit (Hylocereus polyrhizus (Weber) Britton and Rose) peels as affected by encapsulation in maltodextrin-gum Arabic and maltodextrin-pectin matrices. Encapsulation in maltodextrin-gum Arabic and maltodextrin-pectin matrices afforded dry betalain powders after lyophilization. Optical microscopy imaging showed that the betalain powders consisted of matrix-type and shard-like microparticles. ABTS antioxidant assay revealed that maltodextrin-gum Arabic-betalain (MGB) and maltodextrin-pectin-betalain (MPB) microparticles possessed higher antioxidant capacities (195.39 ± 8.63 and 201.76 ± 4.06 µmol Trolox g(-1) microparticles respectively) than the non-encapsulated betalain extract (151.07 ± 2.57 µmol Trolox g(-1) extract). Duck embryo chorioallantoic membrane (CAM) vascular irritation assay showed that the anti-inflammatory activity of encapsulated betalains was five- to six-fold higher than that of non-encapsulated betalains (P ≤ 0.05). Antiangiogenic activity, as evaluated by duck embryo CAM assay, was enhanced two- to four-fold by carbohydrate encapsulation. Glutathione S-transferase (GST)-inducing activity of betalains was likewise improved four- to five-fold. The study showed that the antioxidant, anti-inflammatory, antiangiogenic and GST-inducing activities of betalains from red dragon fruit peels were enhanced through carbohydrate encapsulation. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

    Full Text Available It is a common psychophysical experience that a train of clicks faster than ca. 30 per second is heard as one steady sound, whereas temporal patterns occurring on a slower time scale are perceptually resolved as individual auditory events. This phenomenon suggests the existence of two different neural mechanisms for processing of auditory sequences with fast and slow repetition rates. To test this hypothesis we used Weber’s law, which is known to be valid for perception of time intervals. Discrimination thresholds and Weber fractions (WF for twelve base inter-click intervals (ICI between 5 ms and 300 ms were measured from ten normal hearing subjects by using an up-down staircase algorithm. The mean WF, which is supposed to be constant for any perceptual mechanism according to Weber’s law, displayed significant variation with click rate. WFs decreased sharply from an average value of around 5% at repetition rates below 20 Hz to about 0.5% at rates above 67 Hz. Parallel to this steep transition, subjects reported that at rates below 20 Hz they perceived periodicity as a fast tapping rhythm, whereas at rates above 50 Hz the perceived quality was a pitch. Such a dramatic change in WF indicated the existence of two separate mechanisms for processing the click rate for long and short ICIs, based on temporal and spectral features, respectively. A range of rates between 20 Hz and 33 Hz, in which the rate discrimination threshold was maximum, appears to be a region where both of the presumed time and pitch mechanisms are relatively insensitive to rate alterations. Based on this finding, we speculate that the interval-based perception mechanism ceases to function at around 20 Hz and the spectrum-based mechanism takes over at around 33 Hz; leaving a transitional gap in between, where neither of the two mechanisms is as sensitive. Another notable finding was a significant drop in WF for ICI=100 ms, suggesting a connection of time perception to the EEG

    It is a common psychophysical experience that a train of clicks faster than ca. 30/s is heard as one steady sound, whereas temporal patterns occurring on a slower time scale are perceptually resolved as individual auditory events. This phenomenon suggests the existence of two different neural mechanisms for processing of auditory sequences with fast and slow repetition rates. To test this hypothesis we used Weber’s law, which is known to be valid for perception of time intervals. Discrimination thresholds and Weber fractions (WFs) for 12 base inter-click intervals (ICIs) between 5 and 300 ms were measured from 10 normal hearing subjects by using an “up–down staircase” algorithm.

    We determined the Stillinger-Weber interatomic potential parameters for Si/N/H system based on first principles density functional calculations. This new potential can be used to perform classical molecular dynamics simulation for silicon nitride deposition on Si substrate. During the first principles calculations, cluster models have been carefully and systematically chosen to make sampling of the interatomic potential supersurface more thoroughly. Global optimization method was used to fit the ab initio data into Stillinger-Weber form. We used a recursive method to perform the classical molecular dynamics simulations for silicon nitride (SiN) film growth on Si substrate with SiH4/NH3 gas mixtures. During the simulation, we could clearly observe the silicon nitride film growth progress. In this paper, we present the details of potential derivation and simulation results with different SiH4:NH3 ratios. It is demonstrated that this new potential is suitable to describe the surface reactions of the Si/N/H system and allows us to explore more complex SiN growing process such as plasma-enhanced chemical vapor deposition.

Nela travam-se lutas pelo poder e se fazem relações de poder de forma clara e, às vezes, impositiva. Partindo da abordagem teórica de Weber e Bourdieu, este estudo analisa as relações de poder em duas escolas públicas de periferia de Belo Horizonte, em dois momentos: na interação rotineira do dia-a-dia, quando é exercido o poder simbólico e, em determinados momentos, quando a luta por posições de poder ou pela imposição de idéias desvenda o poder, tornando-o manifesto e revelado.In the first grades of elementary public school, mainly in those located on the poor neighborhood, the circulation of economical and social capital is limited and cultural capital is less required than in the other school levels. However, in these schools power relations take place just like as in any organization. Based on Weber and Bourdieu’s studies this research analyses power relations in two public schools in Belo Horizonte. Two moments have been observed: in the first one, unconscious and subliminal power relations are identified in routine habitual relations among school actors. In the second one, power relations are clearly perceived when strugle for power takes place.

Four cases without neurologic symptoms had no specific abnormality on SPECT and X-ray computed tomography (CT). In 4 cases of so-called Sturge-Weber syndrome with developmental quotients (DQ) or intelligence quotients (IQ) more than 80 and the neurologic symptoms consisting of seizures and hemiplegia, SPECT showed localized reduction of IMP accumulation, and CT exhibited calcification, atrophy and enhancement in 2 cases of 3 with contrast medium infusion in the same areas. In 3 cases with DQ of 50{approx}60 and severer neurologic symptoms, SPECT showed diffuse reduction or defect of IMP accumulation in the ipsilateral hemisphere, and CT exhibited remarkable atrophy, calcifications and enhancement in 2 cases with contrast medium infusion in the same hemisphere. In one case with severe neurologic symptoms, SPECT performed at an early stage showed high IMP accumulation in the ipsilateral hemisphere. (author).

    韦伯具有强烈的民族主义情结,这种情结使他尤为强调学术的文化政治担当,亦使其具有学者和“群众性政治家”双重身份。作为学者,他对现代社会“基于合法律性的合法性”(法理型统治)模式进行了详尽分析;作为群众性政治家,他又明确提出了“领袖民主”(卡理斯玛型统治)合法化模式。这两种理论模式均具有政治现实主义和实证论倾向。哈贝马斯总体上拒绝了韦伯合法化模式的描述性路径,并极力批判了其领袖民主模式;但他亦将其合法化论说建基于韦伯式基于合法律性的合法性模式之上,并做出了可以容纳道德性内容的理论重构。%Weber has a strong nationalist complex which loads him with a special cultural - political promise of the learning and makes him play different roles in his academic career. As a scholar, he gives a highly perceptive analysis of the model of ' legitimacy through legality' ( legal domination) ; while as a ' demagoge'he explicitly puts forth the model of ' Ftihrerdemokratie' ( christmas domination). Both of the two Weberian models of legitimation are the theories with the tendency of positivism. Habermas repudiates the descriptive ap- proach of Weberian model of legitimation in general, and fiercely criticizes Weberian model of ' Ftihrerdemokratie'. Based on Weberian model of' legitimacy through legality' , however, he gives a different theoretical reconstruction which has room for moral elements.

    Objective To investigate the correlation between Sturge-Weber syndrome (SWS) in children with epilepsy and calcification and brain atrophy of cerebral cortex using susceptibility weighted imaging(SWI). Methods Fourteen patients (8 girls and 6 boys; age range, 0.8–10.0 years; mean age, 4.15±2.84 years) with Sturge-Weber syndrome were recruited and performed MRI examination. All patients with unilateral lesions were located in one side of the cerebral hemispheres. MR protocols included axial and sagittal T1-weighted, axial fast spin-echo (FSE) T2-weighted, SWI and contrasted T1-weighted. All raw data of SWI were processed by using the Signal Process in Neuroimage (SPIN) software. After determining the location and realm of SWS lesions, the calciifcation scores of the affected and brain atrophy ratio (BAR) were measured and calculated. The clinical data of each child were recorded, including the age of first seizure, seizure frequency (Score of seizure frequency, SSF),duration of epilepsy and IQ scores. The correlations of calcification scores of the affected and BAR and seizure variables (age of ifrst seizure, SSF and duration of epilepsy) were analyzed by Spearman correlation analysis in SPSS 17.0 software.Result In all, the affected brain parenchyma showed different extent brain atrophy, and then 7 cases with cortex calciifcation. A signiifcantly positive correlation between BAR and calciifcation was found (r =0.78,P=0.00). There was a signiifcantly negative correlations between BAR and ifrst seizure age (r =-0.77,P=0.00). Moreover, a signiifcantly negative correlation (r=0.54,P<0.05) between BAR and IQ scores was also found, meaning the severer atrophy of brain, the lower intelligent level of children. The IQ scores of children with obvious calciifcation (score=2) is signiifcantlydecreased than without calciifcation (score=0) (55±42,96±13,P=0.03).Conclusions There is a relationship between the degree of brain atrophy and the age ofifrst seizure in SWS.

    为获得耐1.5%NaCl的药蒲公英(Taraxacum officinale Weber)愈伤组织.以药蒲公英叶片外植体为材料诱导愈伤组织.以NaCl为选择因子.从愈伤组织直接筛选.在选择培养基上,大部分愈伤组织褐化死亡,个别褐化死亡的愈伤组织周围有少量新的细胞团长出,将其转接到新鲜的选择培养基上,每3周继代一次.经3个月继代筛选获得了耐1.5%NaCl的药蒲公英细胞团.以普通愈伤组织为对照,发现随着NaCl浓度升高,耐盐愈伤组织的相对生长率下降但显著高于对照;且随着盐胁迫处理时间延长持续升高,而普通愈伤组织对照几乎停止生长.说明耐盐愈伤组织具有相对稳定的耐盐性.在蛋白水平上,耐盐愈伤组织与对照愈伤组织差异明显,SDS-PAGE分析显示:耐盐愈伤组织比对照多出一条34 kD大小的蛋白带.且30 kD、18 kD左右的蛋白带明显上调.相同处理条件下耐盐愈伤组织脯氨酸的增加幅度高于对照.盐胁迫条件下,耐盐愈伤组织的超氧化物歧化酶(Super oxidasedimutase,SOD),过氧化物酶(Peroxidase,POD)和过氧化氢酶(Catalase,CAT)活性明显高于对照.且随着处理时间的延长和盐浓度的增加呈现升高的趋势,而对照则呈现先升高后下降的趋势.结果说明耐盐愈伤组织一方面通过小分子有机溶质如脯氨酸的方式调节其渗透平衡,另一方面还可通过提高抗氧化能力降低盐分造成的次级伤害.积累蛋白也可能是耐盐愈伤组织调节渗透平衡的一种方式.通过生理生化分析确定我们获得的耐盐愈伤组织为耐盐变异体.

    Full Text Available Este estudo é uma reflexão sobre  o discurso e a prática nas comunidades Eclesiais de Base no Brasil e na Itália. Buscamos demonstrar, a partir de uma pesquisa empírica e teórica, as relações entres duas Comunidades Eclesiais de Base, a Comunidade San Paolo (Roma-IT e a Prelazia de São Félix (Mato Gross-BR, demonstrando que estas baseiam-se em dois elementos: resultam das discussões  advindas do Concílio Vaticano II e estão fortemente ligadas a seus líderes. E, ainda, que tais comunidades ligam-se por fortes laços simbólicos. Este fato permitiu-nos concluir  que a Teologia da Libertação empenhou-se em promover mudanças sociais e em criar um corpo simbólico que a corroborasse. Tais análises foram sustentadas pela teoria da transformação social de Max Weber e, ainda, pelos estudos  de Karl Mannheim e de  Glock e Stark. Palavras-chaves:Transformação social, Teologia da Libertação, prática, discurso. Abstract This study is a reflection of the discourse and practice on the Basic Ecclesial communities in Brazil and Italy. We try to show, from an empirical and theoretical research, the relations between two Christian Base Communities: the San Paolo Community (Rome – IT and the Prelature of São Félix (BR – Mato Grosso, based on two factors: the result of discussions arising out of Vatican II, and the strong link to its leaders. Such communities bind by strong symbolic ties that really allowed us to conclude that Liberation Theology endeavored to promote social changes and to create a symbolic body that corroborates it. Such analysis was supported by the theory of social transformation of Max Weber, by the studies of Karl Mannheim and Glock and Stark.

    马克斯·韦伯(Max Weber,1864-1920)是德国著名的社会学家,政治经济学家,西方宗教社会学的创始人之一.学者们在谈论他的"理解社会学"时,多从新康德主义学派那里寻找其思想渊源.事实上,对新康德主义哲学思想的借鉴,只是韦伯"理解社会学"的实用主义方法论的一种实施.在这种借鉴的背后涵纳的是马克斯·韦伯社会学方法理论的实用主义倾向.本文从"理想类型"这一"理解社会学"的核心概念的提出及特征和韦伯社会学方法论所表现出来的多元论倾向这两方面解析其"理解社会学"的功利性.

    The root of culture differences between East and West attracts growing attention from many theorists .Max Weber and Joseph Needham have made a relatively systematical and deep argument about this problem .But there are some biases and mis-understandings in their views .Our study shows the root exists in the differences of the traditional thinking paths of two ancient phi -losophies .The philosophic path of the East is to abstract the general concepts from phenomenon , and the West is to decompose things into the fundamental and productive elements .It also means that the former concerns the infinitely spiritual development and the latter concerns the unlimitedly material development .They are just two extreme of the paths .The two civilizations are indispen-sable to the world , yet the roles of two civilizations are obviously different in the different phases .%对于东西方文明差异的根源问题,很多人都已经关注到,韦伯和李约瑟为此作了较为系统和深入的研究,但都存在一定的偏颇与误区。通过细致的梳理和深入的研究发现,两种文明差异的根源,在于古代哲学传统的思维路向不同,即东方哲学主要是沿着将事物抽象为具有统括意义的概念的路向发展,而西方哲学则主要是沿着将事物“提炼”为具有生发作用的“微粒”的路向发展,它们刚好是两个路向的极端。尽管两种文明都不可缺失,但在不同阶段所起的作用是不同的。

    以中国为核心的儒家伦理文化区,虽然其内部也存在宗教,但整个文化区的凝结宗旨是儒家式的伦理文化,即一种以家庭、宗族为基础的文化类型。马克斯·韦伯的《中国的宗教:儒教与道教》以儒家伦理为讨论焦点,从社会生活的诸层面去论证儒家伦理对中国社会的影响,并与西方的新教传统相比较。他着眼于官僚制的阻碍、卡里斯玛的巫术取向以及城市共同体的被压制、救赎宗教的缺失这四个关键特征,去探寻中国在各种社会条件都优于西方的情形下,资本主义未能发展起来的原因。%Within the China-based Confucian culture community, the ethic culture of the Confucian style is prevalent:a type of culture based on family and clan. Max Weber's TheReligionofChina:ConfucianismandTaoism focuses on Confucian ethics, discussing the inlfuences of Confucian ethics on Chinese society from all the aspects of society and making a comparison between it and Western traditions of Protestantism. Max tries to explore why capitalism fails to develop in China where conditions are better than those of the West by concentrating on four key characteristics:impediment to bureaucracy, witchcraft orientation of charisma, the suppression of urban community, and the loss of redemption religion.

    Na Região Centro-Oeste, dadas as condições climáticas, o tomateiro pode ser cultivado o ano inteiro. A produção, no entanto, é baixa e bastante onerosa, em função de diferentes fatores dentre os quais incluem-se as doenças de diferentes etiologias, com destaque para a fúngica provocada por Stemphylium solani, responsável por danos de natureza qualitativa e quantitativa no tomate. Conduziram-se experimentos na Escola de Agronomia da Universidade Federal de Goiás, Goiânia - GO, a uma altitude de 730 m, latitude de 16° 41’S e longitude de 49° 17’W, com temperatura, umidade relativa e precipitação pluviométrica (médias de 23ºC, 82,7 e 62,7mm, respectivamente. O objetivo principal era testar níveis de resistência de variedades comerciais, genótipos pertencentes ao banco de germoplasma da Embrapa-CNPH e geração F1 de tomateiro, em condições de campo a S. solani. As avaliações foram realizadas aos 36, 43, 50, 57, 64, 71, 78 e 85 dias, após o transplantio, combinando escala diagramática e de notas. A diferenciação dos genótipos foi feita através da análise de variância dos valores da área abaixo da curva de progresso de doença, pelo teste de Tukey a 5% de probabilidade e pelo modelo logístico. Dentre as cultivares avaliadas quanto à resistência e/ou à suscetibilidade a S. solani, Ohio 4013, Yoshimatusu e TSW-10 comportaram-se como resistentes, entre os tutorados. Entre os rasteiros, verificou-se este fato na geração F1 (Hawaii 7998 x Monense. Os genótipos Ohio 4013 e o F1 (Hawaii 7998 x Monense foram os que mais se destacaram para resistência a este patógeno, podendo ser indicados para futuros programas de melhoramento.

    In the climate conditions of the Brazilian central west regions, tomato can be cultivated the whole year. However, the production is low and quite onerous in function of different factors Besides, different diseases affect the crop. Among the most being the fungal important is the fungi Stemphylium solani, responsible for damages of qualitative and quantitative nature in tomato. With the objective of finding a way to minimize the effect of these pathogen, an experiment was conduced at the experimental fields of the Federal University of Goiás, Goiânia-GO, Brazil. It is located at an altitude of 730 m, latitude of 16° 41’S and longitude of 49° 17’W, with temperature varying among 20 to for 40ºC, relative humidity (average of the month of 80% in August, 83% in September and 85% in October. Precipitation in August, September and October of 1999 was respectively 0.0 mm, 69.6 mm, and 118.4 mm. The main objectives were to test levels of resistance of commercial varieties, genotypes belonging to the bank of germoplasm of Embrapa-CNPH and F1 generations of tomato Lycopersicon esculentum in field conditions to S. solani. The evaluations were accomplished at the 36, 43, 50, 57, 64, 71, 78 and 85 days after the seedlings planting combining diagramatic scale and grades. Was considered the percentage of infected area on the leaf (PIAL and the also grades: 1 – without symptoms; 2 – spraid lesions; 3 – gathering lesions; 4 – partial dryness of the leaf; 5 – death of the leaf and 6 – death of the plant. The differentiation among genotypes was made through analysis of variance of the values of area under disease progress curve and by of Tukey’s test at the level of 5% of probability and also the logistic model. Regarding resistance to S. solani, Ohio 4013, Yoshimatusu and TSW-10 behaved as resistant, among the indeterminate. Among the determined ones, F1 (Hawaii 7998 x Monense showed higher resistance. The genotypes Ohio 4013 and the F1 (Hawaii 7998 x Monense were the ones that more stood out for resistance to these pathogens and could be suitable for future breeding programs.

    Pterygoplichthys disjunctivus viscera chymotrypsin was purified by fractionation with ammonium sulfate (30-70 % saturation), gel filtration, affinity, and ion exchange chromatography. Chymotrypsin molecular weight was approximately 29 kDa according to sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), shown a single band in zymogram. Electrofocusing study suggested being an anionic enzyme (pI ≈ 3.9), exhibiting maximal activity at pH 9 and 50 °C, using Suc-Ala-Ala-Pro-Phe-p-nitroanilide (SAAPNA) as substrate. Enzyme was effectively inhibited by phenyl methyl sulfonyl fluoride (PMSF) (99 %), and N-tosyl-L-phenylalanine chloromethyl ketone (TPCK) (94 %). Enzyme activity was affected by the following ions in decreasing order: Hg(2+), Fe(2+), Cu(2+), Li(1+), Mg(2+), K(1+), Mn(2+), while Ca(2+) had no effect. Chymotrypsin activity decreased continuously as NaCl concentration increased (from 0 to 30 %). K m and V max values were 0.72 ± 1.4 mM and 1.15 ± 0.06 μmol/min/mg of protein, respectively (SAAPNA as substrate). Results suggest the enzyme has a potential application where low processing temperatures are needed, such as in fish sauce production.

    2013-01-01

    Full Text Available Crops of the tequila plant (Agave tequilana are produced mainly from offshoots of mother plants in established commercial fields. This propagation method is significant, as it is believed that it facilitates the spread of disease because of the crop’s low genetic variability and is also necessary because it is regulate the use of just that variety in tequila industry. Different levels of genetic variability have been reported for A. tequilana and so we tested individuals from representative cultivation zones to determine the actual variability in fields and to assess the genetic structure of populations in commercial plantations. Four additional Agave spp. were used as a control group while Fourcrea spp. individuals were used as an external group. Morphological traits and molecular markers were analyzed. The differences between A. tequilana individuals collected from southern Jalisco state and those collected in the principal Denomination of Origin zone confirmed the existence of different genotypes, which were conserved in different regions by asexual propagation. Leaf length, plant height and number of leaves were the most significant variables that explained the variability within the A. tequilana group. At the molecular level, we found genetic differentiation with a minimum similarity of 0.253 (Jaccard’s coefficient and genetic structure analysis indicated five groups with significant genotypic differences. Genetic structure analysis, grouped accessions according to the dispersion of plant material from the initial sites of cultivation. These results might facilitate the correlation of different groups with crop yield or tequila quality and the establishment of elite lines for breeding programs. It is recommendable in a future, to determinate the different levels of inulines produced by each detected group.

    Fructo-oligosaccharides (FOSs) of a six year old agave plant variety, Agave tequilana, were isolated and fractionated by 2D preparative chromatography (SEC and rpHPLC). Structural analyses of different FOS-fractions were performed by reductive methylation analysis connected to GC/FID identification and NMR-analysis. FOSs from leaves (d.p. 3-8) contain single α-d-Glcp residues as well in terminal as internal position, however (2→1)-linked β-d-Fruf residues only. FOSs from stem, however, contain as well (2→1)- and (2→6)-linked β-d-Fruf residues with branched oligomeric repeating units. These characteristics indicate an enzymatically catalyzed metabolic regulation for the biosynthesis and transformation of fructans in A. tequilana which strongly depends on location and transport activities.

    Fructan, as reserve carbohydrate, supplies energy needs during vegetative development, thereby exhibiting variations in its content and composition. Fructan metabolism in Agave tequilana Blue variety from 2- to 7-year-old plants was analyzed in this work. Soluble carbohydrates were determined at all ages. Fructan (328-711 mg/g), sucrose (14-39 mg/g), fructose (11-20 mg/g), glucose (4-14 mg/g), and starch (0.58-4.98 mg/g) were the most abundant carbohydrates. Thin-layer chromatography exhibited that 2-5-year-old plants mainly stored fructooligosaccharides, while 6-7-year-old plants mainly contained long-chain fructans. The fructan degree of polymerization (DP) increased from 6 to 23 throughout plant development. The 7-year-old plants mainly stored highly branched agavins. Partially methylated alditol acetate analyzed by gas chromatography-mass spectrometry reveals that fructan molecular structures became more complex with plant age. For the first time, we report the presence of a large number of DP3 (seven forms), DP4 (eight forms), and DP5 (six forms) isomers for agave fructans. Overall, fructan metabolism in A. tequilana displays changes in its soluble carbohydrates, DP, type, and fructan structures stored, along its developmental cycle in the field.

    Directory of Open Access Journals (Sweden)

    Andrea Erizi

    2014-05-01

    Full Text Available The aim of this article is to examine Max Weber’s genealog y of liberalism as a political turn paradoxically rooted in two aspects of ascetic Protestantism’s world view: obsession with the purity of our own conscience, and indifference towards other people. This “heterodox” approach to the birth of tolerance is then analyzed in the light of the concept of polytheism. I will argue that Weber’s normative stance on how we should face polytheism is deeply indebted to the ascetic Protestantism’s solution to it, whereas our age tends to conceive of pluralism as relativism, driving the spirit of liberalism away from its origins.

    Full Text Available The figure of Antichrist, linked in recent US apocalyptic thought to President Barack Obama, forms a central component of Christian end-times scenarios, both medieval and modern. Envisioned as a false-messiah, deceptive miracle-worker, and prophet of evil, Antichrist inversely embodies many of the qualities and characteristics associated with Max Weber’s concept of charisma. This essay explores early Christian, medieval, and contemporary depictions of Antichrist and the imagined political circumstances of his reign as manifesting the notion of (anticharisma, compelling but misleading charismatic political and religious leadership oriented toward damnation rather than redemption.

    Heavy metal accumulation produces significant physiological and biochemical responses in vascular plants. Plants growing on abandoned mine sites are of particular interest, since they are genetically tolerant to high metal concentrations. In this work we examined the effect of heavy metals (HM) on the morphology of T. officinale growing on mine soils, with the following objectives: - to determine the fate of HM within the soil-plant system; - to highlight possible damage at anatomical and cytological level; - to assess the resilience capacity of Taraxacum officinale after three years of pot cultivation. Wild specimens of Taraxacum officinale Web, with their soil clod, were gathered from four sites with different contamination levels by heavy metals (Cu, Fe, Pb, Zn) in the abandoned Imperina Valley mine (Northeast Italy). Plants were cultivated in pots at the botanical garden of the University of Florence (HBF), and appeared macroscopically not affected by toxic signals (e.g. reduced growth, leaf necrosis) possibly induced by soil HM concentration. Leaves and roots taken at the same growing season were observed by light microscopy (LM) and transmission electron microscopy (TEM). Light microscopy observations show a clear difference in the cell organization of not-contaminated and contaminated samples. The unpolluted samples present a well organized palisade tissue and spongy photosynthetic parenchyma. Samples from contaminated sites, instead, present a palisade parenchyma less organized, and a reduction of leaf thickness proportional to HM concentration. The poor structural organisations, and the reduced foliar thickness of the contaminated plants, are related to soil contamination. Differences in roots micromorphology concern the cortical parenchyma. Moreover, all the samples examined present mycorrhiza. Ultrastructure observations of the parenchyma cells show mitochondrial structure alteration, with lacking or reduced cristae of the internal membrane at increasing metal content. Instead, chloroplast organization does not present significant differences, particularly in number and compartmentalization of thylakoids. Although macromorphology does not present evidence of phytotoxicity, the recorded observations of the micromorphological characteristics of leaves and roots, show a suffering state of the plants, strictly related to HM content. Leaching reduced partly the HM content of the soil, therefore decreasing their phytotoxic effect. A gradual restoration of leaf organization suggests that somewhat resilience occurred in plants. Moreover, the presence of stress-tolerant mycorrhizal fungi could contribute to reduce metal toxicity. The resilience capacity suggests that Taraxacum could be a useful species in remediation projects. Keywords: Heavy metals • Mine soils • Plant morphology • Taraxacum officinale • Ultrastructure

    For hearing sense, the mechanoreceptors fire action potentials when their membranes are physically stretched. Based on the statistical physics, we analyzed the entropical aspects in auditory processes of hearing. We develop a model that connects the logarithm of relative intensity of sound (loudness) to the level of energy disorder within the system of cellular sensory system. The increasing of entropy and disorder in the system is connected to the free energy available to signal the production of action potentials in inner hair cells of the vestibulocochlear auditory organ.

    The cardinalfish Siphamia tubifer has been selected as a model for the study of genetic connectivity in reef-associated fishes among marine-protected-areas in Socotra Island in the northwestern Indian Ocean (part of the Socotra Archipelago, a UNESCO World Heritage Site since 2008). Twenty-six novel microsatellite markers are described for S. tubifer and are now available for studies on its genetic population structure. In a population sample from Socotra Island, the newly developed markers possessed between three and 20 alleles. Expected and observed heterozygosity ranged from 0.56–0.96 to 0.55–0.95, respectively. The markers did not show deviations from Hardy–Weinberg equilibrium and were not in linkage disequilibrium.

    In vitro micropropagation has been achieved in medicinally important plant, Taraxacum officinale collected from two different regions, Kashmir (J & K) and Garhwal (Uttarakhand). Leaf segments inoculated on MS supplemented with different combinations of Indole-3-acetic acid (IAA) and Benzyladenine (BA) produced indirect regeneration. For root induction MS fortified with Indole-3-butyric acid (IBA) was used. Taraxacum officinale collected from Garhwal responded two weeks earlier and showed shoot regeneration whereas in Kashmir population only callus proliferation occurred. Esculin content was also higher in the samples from Garhwal. The content was affected by both, the hormone concentration as well as age of the cultures. RAPD of the in vitro raised regenerants confirmed genetic stability.

    Energy Technology Data Exchange (ETDEWEB)

    Derakhshani, Maaneli, E-mail: maanelid@yahoo.com

    2014-03-01

    We propose a Newtonian semiclassical gravity theory based on the GRW collapse theory with matter density ontology (GRWm), which we term GRWmN. The theory is proposed because, as we show from previous arguments in the literature, the standard Newtonian semiclassical gravity theory based on the Schroedinger–Newton equations does not have a consistent Born rule probability interpretation for gravitationally self-interacting particles and implies gravitational cat states for macroscopic mass superpositions. By contrast, we show that GRWmN has a consistent statistical description of gravitationally self-interacting particles and adequately suppresses the cat states for macroscopic superpositions. Two possible routes to experimentally testing GRWmN are also considered. We conclude with a discussion of possible variants of GRWmN, what a general relativistic extension would involve, and various objections that might be raised against semiclassical gravity theories like GRWmN.

    Philippe Beaucage and Normand Mousseau Département de physique and RQMP, Université de Montréal We present a numerical study of the nucleation process leading to the crystallization of a 10648-atoms system. With elementary building blocks of diamond and wurtzite structure as a criterion for the recognition of the crystalline nuclei in the supercooled liquid, we can directly follow the phase transition. Out of the nine NVT trajectories we generate, six crystallizes in less than 10 ns. By following the trajectory of the stable cluster which will eventually nucleate, we can identify the different regimes of the nucleation process. The path to crystallization can also be analysed in terms of the classical nucleation theory (CNT). For example, the lifetime distribution of clusters as a function of their size is well represented by an inversed Gaussian, as can be derived from CNT. However, there are some strong discrepancies with the CNT predictions of the free energy curve. A number of hypotheses are studied to identify the source of this discrepancy.

    Primary ankle arthrodesis used to treat a neglected open ankle fracture dislocation is a unique decision. A 63-year-old man presented to the emergency department with a 5-day-old open fracture dislocation of his right ankle. After thorough soft tissue debridement, primary arthrodesis of the tibiotalar joint was performed using initial Kirschner wire fixation and an external fixator. Definitive soft tissue coverage was later achieved using a latissimus dorsi free flap. The fusion was consolidated to salvage the limb from amputation. The use of primary arthrodesis to treat a compound ankle fracture dislocation has not been previously described.

    The consumption of yolk on development of embryos of the salmon-red rainbowfish (Glossolepis incisus was examined under controlled hatchery conditions. Naturally-fertilized eggs, obtained by natural spawning of cultured adults, were stocked into floating sieves in 40L flow-through aquaria at temperature of 28°C. A photoperiod of 16L: 8D was maintained. The embryos have a long period of hatching about 7 days at 28ºC, consuming almost all yolk during the early stages into the eggs. At hatching the newly-hatched larvae yolk-sac is reduced, but still present and the larvae are strongly swimmers and have a functional mouth, enteric peristaltic movement and anus opened suggesting an initial exogenous feeding stage. Differently to others species of tropical fishes that have a long time for the weaning, larvae of salmon-red rainbowfish are already for becoming first-feeding larvae in few hours after eclosion.

    KEY WORDS: Early development, ontogeny, ornamental fish.

Os ovos foram obtidos por desovas naturais de matrizes em cativeiro e mantidos em peneiras em aquários de 40L, com fluxo contínuo de água por bombeamento, na temperatura de 28��C. O fotoperíodo mantido durante o experimento foi de 16L:8E. Os embriões demonstraram um longo período de incubação, em torno de sete dias, e consumiram quase todo o vitelo durante o período embrionário, ainda dentro dos ovos. Após a eclosão, a vesícula vitelínica das larvas recém-eclodidas é muito reduzida, mas ainda presente. As larvas recém-eclodidas apresentaram muita atividade natatória, uma boca funcional, movimentos peristálticos entéricos e ânus aberto sugerindo estar em fase inicial de alimentação exógena. Diferentemente de outras espécies de peixes tropicais que possuem um longo período de tempo para a transição alimentar, as larvas de melanotênia-maçã estão prontas para a alimentação exógena em poucas horas após a eclosão.

Un paradigma potente y muy exitoso, no sólo ante los historiadores, sino también en la opinión pública culta. Para explicar un tema de este alcance, la metodología utilizada en el texto ha sido analizar selectivamente las ideas de autores y grupos representativos y sobresalientes, que tuvieron una indiscutible influencia sobre los demás. La tesis más o menos implícita es que las condiciones actuales del mundo tras la caída del Muro de Berlín ponen a la vista la necesidad de ir más allá de este paradigma, de modo de recuperar la autonomía histórica de cada uno de los dos siglos, cosa especialmente importante en el caso de América Latina.The article aims to explain how and why, between the two world wars, a historiography paradigm was built.

To study this topic the article analyzes a series of ideas of important authors and groups that had an indisputable influence in the historical discipline. The thesis that is advanced in this text is that, in the current conditions of the world, after the Berlin wall, it is necessary to recuperate the autonomy of the two centuries, especially for the Latin American case.

    2011-01-01

    An analysis of ground-based observations of solar irradiance was recently published in this journal, reporting an apparent increase of solar irradiance on the ground of the order of 1% between solar minima and maxima [1]. Since the corresponding variations in total solar irradiance on top of the atmosphere are accurately determined from satellite observations to be of the order of 0.1% only [2], the one order of magnitude stronger effect in the terrestrial insolation data was interpreted as evidence for cosmic-ray induced aerosol formation in the atmosphere. In my opinion, however, this result does not reflect reality. Using the energy budget of Earth's surface, I show that changes of ground-based insolation with the solar cycle of the order of 1% between solar minima and maxima would result in large surface air temperature variations which are inconsistent with the instrumental record. It would appear that the strong variations of terrestrial irradiance found by [1] are due to the uncorrected effects of volcanic or local aerosols and seasonal variations. Taking these effects into account, I find a variation of terrestrial insolation with solar activity which is of the same order as the one measured from space, bringing the surface energy budget into agreement with the solar signal detected in temperature data.

    The The effects of air-to-liquid ratio (β) and void fraction (α) on Sauter mean diameter (SMD or D32), arithmetic mean diameter (D10), surface mean diameter (D20), volume mean diameter (VMD or D20), and radial velocity profiles were experimentally investigated for a two-phase gas/liquid (TPGL) nozzle with a hybrid design of classical twin-fluid and effervescent nozzles. Radial spray profiles were measured using a Phase-Doppler-Particle-Anemometer (PDPA) system on 15Dn, 30Dn, 60Dn, 120Dn;(Dn represents nozzle diameter = 3.10,mm) axial distances. In addition, the effects of spray break-up patterns were analyzed with changing axial distances. The average void fraction in the feeding conduit (FC) was measured by a pneumatic controlled quick-closing-valve (QCV). The experiments were performed using mixtures of air with water at water flow rates of 1.50 to 7.50 kg/min and air-to-liquid mass ratios (β) of 0.30 to 10;%. The length and diameter of the FC was 36.8,cm and 6.35,mm, respectively. Result indicates that as the St number reaches the value of one, no more break-up continues, thus the droplets start to coalesce each other forming bigger droplets (higher D10 values) with increasing radial distances. Knowledge from this study will provide better understanding that ensures an increase in plant efficiency and product yield in oil sands bitumen upgrading.

Different types of agave leaves were isolated, classified, and their content in the total plant determined. The usable fractions were collected and their properties determined. Of the total wet weight of the agave plant, 54% corresponds to the agave head, 32% corresponds to materials which could be usable for sugar and fiber production which leaves 14% of the wet plant without apparent utility. The fractions with higher total reducing sugars (TRS) content were the fresh fraction of partially dry leaves stuck to the head and the leaf bases with a TRS content of 16.1% and 13.1%, respectively. The highest TRS concentration (16-28%) is in the agave head which is used for tequila production. The leaves are 90-120 cm long and 8-12 cm wide and contain fiber bundles that are 23-52 cm long and 0.6-13 mm wide. The ultimate fiber length is approximately 1.6 mm with an average width of 25 microns. There are several types of leaf fibers that can be utilized depending on what part of the plant they come from and what product is desired. Agave leaf fibers were pulped using a soda pulping process and the pulp was hand formed into test sheets. Test sheets made from pulped agave leaf fibers had a breaking length comparable to paper made from both pine and eucalyptus fibers, but the tear index and burst index were lower than the other two papers.

  9. Proteins in the roots of the perennial weeds chicory (Cichorium intybus L.) and dandelion (Taraxacum officinale Weber) are associated with overwintering.

    Roots are the overwintering structures of herbaceous perennial weeds growing in temperate climates. During the fall they accumulated reserves which are remobilized when growth resumes in the spring. An 18kDa (kilodalton) protein increases in both chicory and dandelion roots during the fall months. The proteins in both species are antigenically similar, and are recognized also by an antibody to a storage-protein deposited in Jerusalem artichoke (Helianthus tuberosus) tubers. In chicory, the protein is root-specific, but in dandelion it is detectable in the flowers, vestigial stem and the seed. Electrophoretic characterization of the 18-kDa protein shows that it is a single polypeptide, without subunits, with charge isomers of pI values close to pH 6.5. The major protein present in chicory and dandelion roots is unlike the vegetative storage proteins recently found in soybean or the storage proteins in the bark of trees.

    The inhibitory effects of Grcilaria lemaneiformis on the co-cultured Scrippsiella trochoidea were determined under controlled laboratory conditions, and the possible mechanism was studied. Results showed that: (1) in the separating S. trochoiea-G. lemaneormis co-culture system when the initial cell density of C. lemaneaonis was set at 0.5 g x L(-1), the growth of S. trochoidea was obviously inhibited and its maximum cell density and exponential phase were decreased compared with the control; however, the inhibitory effect was not as strong as that in the direct cell-cell contact co-culture. Result showed that allelopathy basing on the direct cell contact was the most possible reason leading to the observed result; (2) when the initial cell density of G. lemaneiformis was set at 0.2 g'L-' in the direct cell-cell contact co-culture, the intracellular nitrate concentration of S. trochoidea in monoculture system was 1.5 times of that in co-culture. It seemed that G. lemaneiformis could competitively absorb the environmental nitrate and ultimately led to the decrease of the stock of intracellular nitrate of S. trochoidea.

  3. Small heat-shock proteins and leaf cooling capacity account for the unusual heat tolerance of the central spike leaves in Agave tequilana var. Weber.

    Luján, Rosario; Lledías, Fernando; Martínez, Luz María; Barreto, Rita; Cassab, Gladys I; Nieto-Sotelo, Jorge

    2009-12-01

    Agaves are perennial crassulacean acid metabolism (CAM) plants distributed in tropical and subtropical arid environments, features that are attractive for studying the heat-shock response. In agaves, the stress response can be analysed easily during leaf development, as they form a spirally shaped rosette, having the meristem surrounded by folded leaves in the centre (spike) and the unfolded and more mature leaves in the periphery. Here, we report that the spike of Agave tequilana is the most thermotolerant part of the rosette withstanding shocks of up to 55 degrees C. This finding was inconsistent with the patterns of heat-shock protein (Hsp) gene expression, as maximal accumulation of Hsp transcripts was at 44 degrees C in all sectors (spike, inner, middle and outer). However, levels of small HSP (sHSP)-CI and sHSP-CII proteins were conspicuously higher in spike leaves at all temperatures correlating with their thermotolerance. In addition, spike leaves showed a higher stomatal density and abated more efficiently their temperature several degrees below that of air. We propose that the greater capacity for leaf cooling during the day in response to heat stress, and the elevated levels of sHSPs, constitute part of a set of strategies that protect the SAM and folded leaves of A. tequilana from high temperatures.

UPD, S:L ratio, and plant age all affected YC, FRU, and DPn. Maximum YC and FRU were obtained from the older agave with UPD and S:L ratio of 120 mW/mL and 1:6, respectively; while glucose, fructose, and sucrose were highly released from the younger plant. Agave of 7-year-old presented the highest DPn. Fructan degradation occurred at high UPD, increasing the simple sugars and decreasing the DPn. Thermal-traditional extraction without sonication caused more fructan degradation; and overall, ultrasound enhanced fructan extraction and minimized fructan damage, representing a technological alternative for fructan extraction from agave.

    1997-11-01

    Full Text Available Rediscovering Antiquity is an example of the genre of historical writing which seeks to recast the careers of little-known figures who have fallen into obscurity. This is typically intended to move them and their work into the proper "lineage," that is, the select group of ancestral figures from which modern practices are derived. Parslow is interested in the 18th century excavations of the Vesuvian cities, which, he argues, have been misunderstood by historians of archaeology. Indeed, common sources, such as Daniel (1981:55, describe the initial explorations of Pompeii, Herculaneum, and Stabiae, sponsored by the Bourbon kings of Naples as "...treasure hunts and not serious excavations." While the Roman artifacts removed from the sites are credited with spurring interest in antiquity in Enlightenment Europe, modern scholars have until now devoted little attention to the means through which they were recovered.

    韦伯的研究方法包含着三个有机的组成部分,即价值关联、理想类型和价值中立.韦伯方法论学说的意义在于:从方法论的整体主义走向个体主义,从寻求社会规律本质上的因果关系到发现个别社会现象的多因果关系,从追求社会科学功用的全能期望到有意识的自我限制.

    马克斯·韦伯的民族主义思想,一直受到许多思想家的关注,也引起了诸多的争论.本文试图把韦伯的民族主义思想与他对现代政治的理解结合起来分析.通过考察韦伯民族主义产生的思想背景和现实历史条件,笔者认为韦伯是一个政治上的民族主义者.在韦伯的思想视界里,处于现代世界体系中的民族国家充满了为了国家生存而展开的激烈政治斗争,实力政治是民族国家的必要基础,国家生存和大国梦想是民族国家最主要的政治诉求,也是韦伯民族主义思想的精髓与实质.韦伯正是以此来理解德国在世界政治中的现实处境和成为一个政治大国的希望的.

    @@ 一、价值中立与理性诚实 韦伯关于"世界脱魔"的说法,在很大程度上导致了后人在理论上把"诸神复活"视为现代人面临的价值领域的基本现状.对韦伯世界观进行的批判,大多都是从这个问题切入的.麦金太尔不仅把韦伯归人"情感主义"伦理观之列,并认为韦伯的世界观就是"当代主导地位的世界观"(麦金太尔,1995:137).哈贝马斯从另一侧面批评韦伯因强调工具理性而只能把价值领域视为无法通约、缺乏共识的主观世界.然而,无论麦金太尔还是哈贝马斯都不会否认,在宇宙大序不复存在的现代社会,价值多元性乃是一个不争的事实.问题只是,我们是否还有可能重新建构秩序,而这又与我们如何理解"世界脱魔"直接相关.以麦金太尔为代表的悲观论对重构大序并不抱希望,他认为,世界从一种人与人之间的非操纵性关系进入另一种操纵性关系,其实质是,前者赖以存在的共同道德基础已经完全丧失,因此,启蒙运动以来的一切重建道德的努力都只能归于失败.所以,这个时代是以韦伯社会学的权力取向和控制理论作为基本特征的(麦金太尔,1995).
