Copto-Arabic Universal Chronography. Between Antiquity, Judaism, Christianity and Islam The K. al-Tawārīkh of N. al-Khilāfa Abū Shākir Ibn al-Rāhib (655 Heg. / 973 Mart. / 1257 Chr. / 1569 Alex. / 6750 AM)

La obra histórica del erudito y enciclopedista de la edad de oro de la literatura árabe copta, de la cual el Dr. Samuel Moawad (Munster) está preparando una edición, representa en realidad una colección de tres tratados divididos artificialmente en 51 capítulos secuenciales. El núcleo cronológico es precedido por un largo tratado con 47 capítulos sobre cálculos astronómicos y eclesiásticos así como épocas históricas y calendarios de diferentes naciones. La parte histórica propia (ch. 48-50), de los cuales el llamado Chronicon orientale representa una deficiente revisión anónima, trata sucesivamente de historia universal, dinastías islámicas y patriarcas coptos. Un sumario histórico, así como dogmático, de los primeros siete/ocho concilios de la Iglesia cristiana (cap. 51) termina la compilación entera. El conocido historiador al-Makin Ibn al-.Amid hace un gran uso de la labor de su contemporáneo y, al parecer a través de él, los grandes historiadores musulmanes: Ibn Khaldun, Maqrizi o Qalqashandi hacen mención continua de Ibn al-Rahib. Más tarde en el siglo XVI, el K. al-Tawarikh fue traducido en etiópico y tuvo un gran impacto en la literatura histórica y computacional de los etíopes.

Cheering the soul: Ibn Qāḍī Baʿlabakk’s Mufarriḥ an-Nafs. Arabic edition, english translation, study and glossaries

The Mufarriḥ an-nafs (Soul-Cheerer), attributed to Badr ad-Dīn Muẓaffar Ibn Qāḍī Baʿlabakk, who served under the Ayyubids as the Chief Medical Officer of Damascus in the mid-13th century, was written as a comprehensive guide for physicians outlining different approaches to cheering the soul. The tractate is divided into ten chapters, which explore the nature of the soul, its distinction to the body as well as their connection through sensorial perception. Ibn Qāḍī Baʿlabakk distinguishes the bodily senses – hearing, vision, smell, taste, touch – and the inner senses, which he sees as stimulated through activities such as hunting and engagement in poetry and the sciences. The seventh chapter of the Mufarriḥ an-nafs includes an extended encyclopedia on materia medica as well as dispensatory of simple and compound drugs, which is devoted to treating the soul and remains unparalleled in the history of Islamicate medicine. My doctoral dissertation offers a complete recension and translation of the Mufarriḥ an-nafs based on a stemma codicum drawn from the seventeen extant text witnesses. The dissertation contextualizes the work, its author as well as sources, and features a text commentary that seeks to enable the reader to easily place and understand the Mufarriḥ an-nafs within the tradition of Galenic medicine. The glossaries on materia medica found at the end of the dissertation are aimed at facilitating access to the pharmacological dispensatory included in the seventh chapter.

Validity and reliability of the Structured Clinical Interview for Mood Spectrum: Brazilian version (SCIMOODS-VB)

OBJECTIVE: The aim of this study was to translate the Structured Clinical Interview for Mood Spectrum into Brazilian Portuguese, measuring its reliability, validity, and defining scores for bipolar disorders. METHOD: Questionnaire was translated (into Brazilian Portuguese) and back-translated into English. Sample consisted of 47 subjects with bipolar disorder, 47 with major depressive disorder, 18 with schizophrenia and 22 controls. Inter-rater reliability was tested in 20 subjects with bipolar disorder and MDD. Internal consistency was measured using the Kuder Richardson formula. Forward stepwise discriminant analysis was performed. Scores were compared between groups; manic (M), depressive (D) and total (T) threshold scores were calculated through receiver operating characteristic (ROC) curves. RESULTS: Kuder Richardson coefficients were between 0.86 and 0.94. Intraclass correlation coefficient was 0.96 (CI 95 % 0.93-0.97). Subjects with bipolar disorder had higher M and T, and similar D scores, when compared to major depressive disorder (ANOVA, p < 0.001). The sub-domains that best discriminated unipolar and bipolar subjects were manic energy and manic mood. M had the best area under the curve (0.909), and values of M equal to or greater than 30 yielded 91.5% sensitivity and 74.5% specificity. CONCLUSION: Structured Clinical Interview for Mood Spectrum has good reliability and validity. Cut-off of 30 best differentiates subjects with bipolar disorder vs. unipolar depression. A cutoff score of 30 or higher in the mania sub-domain is appropriate to help make a distinction between subjects with bipolar disorder and those with unipolar depression.

Humor, desidealização e sublimação na psicanálise

A motivação principal deste artigo é demonstrar que a metapsicologia do humor se oferece, na obra freudiana, como o paradigma a partir do qual se podem compreender as operações em jogo no processo da sublimação. Percebe-se, assim, que a associação entre duas problemáticas sombreadas pela tradição psicanalítica - o humor e a sublimação - contribui para o esclarecimento de ambas. Ao longo do texto são enfatizados o trabalho de desidealização promovido pelo humor, a modalidade identificatória envolvida na sua produção, a referência do humor negro à condição de orfandade que caracteriza o sujeito moderno, bem como a política que acompanha a anunciação do dito humorístico e, mesmo, do Witz (espirituosidade) de modo geral. Finalmente, demonstra-se a filiação do humor ao realismo grotesco, amplamente analisado por Mikhail Bakhtin, indicando como, na enunciação humorística, é preciso considerar a participação da alegria, sua força motriz.

VEGETABLE OIL STRUCTURE AND ANTIOXIDANTS

Five vegetable oils: canola, soybean, corn, cottonseed and sunflower oils were characterized with respect to their composition by gas chromatography and viscosity. The compositions of the vegetable oils suggest that they exhibit substantially different propensity for oxidation following the order of: canola < corn < cottonseed < sunflower approximate to soybean. Viscosities at 40 degrees C and 100 degrees C and the viscosity index (VI) values were determined for the vegetable oils and two petroleum oil quenchants: Microtemp 157 (a conventional slow oil) and Microtemp 153B (an accelerated or fast oil). The kinematic viscosities of the different vegetable and petroleum oils at 40 degrees C were similar. The VI values for the different vegetable oils were very close and varied between 209-220 and were all much higher than the VI values obtained for Microtemp 157 (96) and Microtemp 153B (121). These data indicate that the viscosity variations of these vegetable oils are substantially less sensitive to temperature variation than are the parafinic oil based Microtemp 157 and Microtemp 153B. Although these data suggest that any of the vegetable oils evaluated could be blended with minimal impact on viscosity, the oxidative stability would surely be substantially impacted. Cooling curve analysis was performed on these vegetable oils at 60 degrees C under non-agitated conditions. These results were compared with cooling curves obtained for Microtemp 157, a conventional, unaccelerated petroleum oil, and Microtemp 153B, an accelerated petroleum oil under the same conditions. The results showed that cooling profiles of the different vegetable oils were similar as expected from the VI values. However, no boiling was observed wit any of the vegetable oils and heat transfer occurs only by convection since there is no full-film boiling and nucleate boiling process as typically observed for petroleum oil quenchants, including those of this study. Therefore, high-temperature cooling is considerable faster for vegetable oils as a class. The cooling properties obtained suggest that vegetable oils would be especially suitable fur quenching low-hardenability steels such as carbon steels.

Resident tissue macrophages within the normal rat iris lack immunosuppressive activity and are effective antigen-presenting cells

Despite extensive study of the numerous immunoregulatory mechanisms that contribute to the immune-privileged nature of the anterior chamber (AC) of the eye, little is known of the functional nature of antigen-presenting cells (APC) present in the tissues adjoining the AC. In the present study, we have compared the antigen-presenting capacity of dendritic cells (DC) and macrophages isolated from the normal rat iris. Whereas iris DC exhibited a potent ability to stimulate resting allogeneic T cells in MLR cultures (an in-vitro correlate of the ability to induce primary T cell responses), resident iris macrophages displayed negligible MLR-stimulatory capacity. Significantly, iris macrophages could efficiently elicit proliferation of primed antigen-specific T cells (an in-vitro correlate of the ability to act as local APC in secondary responses). This antigen-presenting activity was approximately half that of fully mature iris DC and considerably greater than that of freshly isolated iris DC. A key contributor to the effectiveness of resident iris macrophage antigen presentation was considered to be the absence of lymphocytostatic control of T cell proliferation exerted by these cells. The results indicate dichotomous but complementary roles for DC (immune surveillance) and macrophages (local antigen presentation in secondary responses) in this tissue.

Listening to the Whispers of Matter Through Arabic Hermeticism: New Studies on the Book of the Treasure of Alexander

The Jabirian Corpus refers to the K. Thahirat Al-`Iskandar, ""The Book of the Treasure of Alexander"" (hereafter BTA), as one of several forgeries suggesting that alchemical secrets were hidden in inscriptions in various places. The book was neglected until 1926, when Julius Ruska discussed it in his work on the Emerald Tablet, placing the BTA within the literature related to the development of Arabic alchemy. His preliminary study became an essential reference and encouraged many scholars to work on the BTA in the following decades. Some years ago, we completed the first translation of the BTA into a Western language. The work was based on the acephalous Escorial manuscript, which we identified as a fourteenth-century copy of the BTA. This manuscript is peculiar, as part of it is encoded. After finishing our translation, we started to establish the text of the BTA. At present, the text is in process of fixation-to be followed by textual criticism-and has been the main focus of a thorough study of ours on medieval hermeticism and alchemy. A sample of the work currently in progress is presented in this paper: an analysis of the variations between different manuscripts along with a study and English translation of its alchemical chapter.

Increased cardiac sympathetic drive and reduced vagal modulation following endothelin receptor antagonism in healthy conscious rats

1. The present study evaluated changes in autonomic control of the cardiovascular system in conscious rats following blockade of endothelin (ET) receptors with bosentan. 2. Rats were treated with bosentan or vehicle (5% gum arabic) for 7 days by gavage. 3. Baseline heart rate (HR) was higher in the bosentan-treated group compared with the control group (418 +/- 5 vs 357 +/- 4 b.p.m., respectively; P < 0.001). This baseline tachycardia was associated with a lower baroreflex sensitivity of the bradycardiac and tachycardiac responses in the bosentan-treated group compared with the control group. Sequential blockade of the parasympathetic and sympathetic autonomic nervous system with methylatropine and propranolol showed a higher intrinsic HR in the bosentan-treated group compared with the control group (411 +/- 5 vs 381 +/- 4 b.p.m., respectively; P < 0.05). This was accompanied by a higher cardiac sympathetic tone (31 +/- 1 vs 13 +/- 1%, respectively; P < 0.01) and a lower vagal parasympathetic tone (69 +/- 2 vs 87 +/- 2%, respectively; P < 0.01) in the bosentan-treated group compared with the control group. Variance and high-frequency oscillations of pulse interval (PI) variability in absolute and normalized units were lower in the bosentan-treated group than in the control group. Conversely, low-frequency (LF) oscillations of PI variability in absolute and normalized units, as well as variance and LF oscillations of systolic arterial pressure variability, were greater in the bosentan-treated group than the control group. 4. Overall, the data indicate an increased cardiac sympathetic drive, as well as lower vagal parasympathetic activity and baroreflex sensitivity, in conscious rats after chronic blockade of ET receptors with bosentan.

Molecular Epidemiology of Avian Infectious Bronchitis in Brazil from 2007 to 2008 in Breeders, Broilers, and Layers

Multiple lineages of Brazilian strains from 2007 to 2008 of avian infectious bronchitis virus (IBV) were detected in flocks of breeders, broilers, and layers. Organs samples from 20 IBV-positive flocks with variable clinical signs were submitted to the partial amplification of S gene (nucleotides 726-1071) of IBV. Fifteen of the 20 sequenced strains segregated in a unique Brazilian cluster subdivided in three subclusters (Brazil 01, 02, and 03). Whereas three strains could be classified as Massachusetts (Mass) genotype, the remaining two strains, originating from flocks with reproductive and respiratory disorders, grouped within the 4/91-793B genotype, a genotype that has not been detected before in Brazil. The potential relevance of the findings to the poultry industry is discussed because the low level of identity of the sequenced part of the S gene from 17 of 20 detected field strains and the vaccines of the Massachusetts serotype used suggest that the level of cross-protection by the Massachusetts vaccines might be low.

Quantitative analysis of the speed and accuracy of tongue movements in dysarthria subsequent to traumatic brain injury using electromagnetic articulography

It has been recognised that in order to study the displacement, timing and co-ordination of articulatory components (i.e., tongue. lips, jaw) in speech production it is desirable to obtain high-resolution movement data on multiple structures inside and outside the vocal tract. Until recently, with the exception of X-ray techniques such as cineradiography, the study 0. speech movements has been hindered by the inaccessibility of the oral cavity during speech. X-ray techniques are generally not used because of unacceptable radiation exposure. The aim of the present study was to demonstrate the use of a new physiological device, the electromagnetic articulograph, for assessing articulatory dysfunction subsequent to traumatic brain injury. The components of the device together with the measuring principle are described and data collected from a single case presented. A 19 year-old male who exhibited dysarthria subsequent to a traumatic brain injury was fitted wit 2 the electromagnetic articulograph (Carstens AG-100) and a kinematic analysis of his tongue movements during production of the lingual consonants it, s, k/ within single syllable words was performed. Examination of kinematic parameters including movemmt trajectories, velocity, and acceleration revealed differences in the speed and accuracy of his tongue movements compared to those produced by a non-neurologically impaired adult male. It was concluded that the articulograph is a useful device for diagnosing speed and accuracy disorders in tongue movements during speech and that the device has potential for incorporation into physiologically based rehabilitation programs as a real-time biofeedback instrument.

Visual Biology of Hawaiian Coral Reef Fishes. I. Ocular Transmission and Visual Pigments

The visual biology of Hawaiian reef fishes was explored by examining their eyes for spectral sensitivity of their visual pigments and for transmission of light through the ocular media to the retina. The spectral absorption curves for the visual pigments of 38 species of Hawaiian fish were recorded using microspectrophotometry. The peak absorption wavelength (lambda(max)) of the rods varied from 477-502 nm and the lambda(max) of individual species conformed closely to values for the same species previously reported using a whole retina extraction procedure. The visual pigments of single cone photoreceptors were categorized, dependent on their lambda(max)-values, as ultraviolet (347-376 nm), violet (398-431 nm) or blue (439-498 nm) sensitive cones. Eight species possessed ultraviolet-sensitive cones and 14 species violet-sensitive cones. Thus, 47% of the species examined displayed photosensitivity to the short-wavelength region of the spectrum. Both identical and nonidentical paired and double cones were found with blue sensitivity or green absorption peaks (> 500 nm). Spectrophotometry of the lens, cornea, and humors for 195 species from 49 families found that the spectral composition of the light transmitted to the retina was most often limited by the lens (73% of species examined). Except for two unusual species with humor-limited eyes, Acanthocybium solandri (Scombridae) and the priacanthid fish, Heteropriacanthus cruentatus, the remainder had corneal-limited eyes. The wavelength at which 50% of the light was blocked (T50) was classified according to a system modified from Douglas and McGuigan (1989) as Type I, T50 < = 355 nm, (32 species); Type IIa, 355 < T50 < = 380 nm (30 species); Type IIb, 380 < T50 405 nm (84 species). Possession of UV-transmitting ocular media follows both taxonomic and functional lines and, if the ecology of the species is considered, is correlated with the short-wavelength visual pigments found in the species. Three types of short-wavelength vision in fishes are hypothesized: UV-sensitive, UV-specialized, and violet-specialized. UV-sensitive eyes lack UV blockers (Type I and IIa) and can sense UV light with the secondary absorption peak or beta peak of their longer wavelength visual pigments but do not possess specialized UV receptor cells and, therefore, probably lack UV hue discrimination. UV-specialized eyes allow transmission of UV light to the retina (Type I and IIa) and also possess UV-sensitive cone receptors with peak absorption between 300 and 400 nm. Given the appropriate perceptual mechanisms, these species could possess true UV-color vision and hue discrimination. Violet-specialized eyes extend into Type IIb eyes and possess violet-sensitive cone cells. UV-sensitive eyes are found throughout the fishes from at least two species of sharks to modern bony fishes. Eyes with specialized short-wavelength sensitivity are common in tropical reef fishes and must be taken into consideration when performing research involving the visual perception systems of these fishes. Because most glass and plastics are UV-opaque, great care must be taken to ensure that aquarium dividers, specimen holding containers, etc., are UV-transparent or at least to report the types of materials in use.

Caminhos retóricos e sorrisos incômodos : argumentação e humor em "A encalhada", de Ingrid Guimarães e Aloísio Abre

Esta dissertação aborda a construção retórica da comicidade em peças teatrais. Para tanto, propõe a investigação das estratégias retóricas que enfatizam o efeito cômico no esquete “A encalhada”, de Ingrid Guimarães e Aloísio de Abreu – uma das nove cenas que compõem o espetáculo Cócegas (EMI, 2004), interpretado pelas atrizes brasileiras Heloísa Périssé e Ingrid Guimarães. O embasamento teórico para este trabalho é fornecido, principalmente, pelos tratados da Retórica Antiga (ARISTÓTELES, 1991, 2000a, 2005; CÍCERO, 1950, 1991; QUINTILIANO, 1836), pelos estudos da Nova Retórica (PERELMAN; OLBRECHTS-TYTECA, 1996; REBOUL, 1998; MEYER, 1994, 2007a, 2007b) e por obras que versam sobre a comédia (FRYE, 1973; MENDES, 2008). Finda a análise dos componentes verbais e não verbais do esquete, constata-se que a recorrência de algumas técnicas no plano da expressão, como o disfemismo, a repetição, a alusão; e a constituição do caráter ansioso e imoderado da protagonista são estratégias fundamentais na produção do efeito cômico em “A encalhada”. Além disso, verifica-se que interação entre os diferentes expedientes retóricos do esquete é capaz de incitar, no auditório, paixões eufóricas, como a confiança e a simpatia; e disfóricas, como a inveja.

Spatial variability in nutritional status of arabic coffee based on dris index

The combined use of precision agriculture and the Diagnosis and Recommendation Integrated System (DRIS) allows the spatial monitoring of coffee nutrient balance to provide more balanced and cost-effective fertilizer recommendations. The objective of this work was to evaluate the spatial variability in the nutritional status of two coffee varieties using the Mean Nutritional Balance Index (NBIm) and its relationship with their respective yields. The experiment was conducted in eastern Minas Gerais in two areas, one planted with variety Catucaí and another with variety Catuaí. The NBIm of the two varieties and their yields were analyzed through geostatistics and, based on the models and parameters of the variograms, were interpolated to obtain their spatial distribution in the studied areas. Variety Catucai, with grater spatial variability, was more nutritional unbalanced than variety Catuai, and consequently produced lower yields. Excess of Fe and Mn makes these elements limiting yield factors.

Transtornos do humor em enfermaria de clínica médica e validação de escala de medida (HAD) de ansiedade e depressão

Para estimar a prevalência de transtornos do humor, foram utilizadas a entrevista estruturada, "Clinical Interview Schedule" (CIS-R), e a escala "Hospital Anxiety and Depression" (HAD) em 78 pacientes internados em uma enfermaria geral de adultos (43 homens e 35 mulheres, média de idade = 43,2 anos). Foi encontrada prevalência instantânea de 39% de transtornos do humor. Dezesseis (20,5%) pacientes preencheram critérios para ansiedade, a maioria dos casos sendo de gravidade leve. Vinte e seis (33%) casos de depressão foram detectados, 7 dos quais de gravidade moderada. Observou-se uma combinação de sintomas de preocupação, depressão, ansiedade e insônia. A HAD mostrou-se de fácil compreensão pelos pacientes. As subescalas de ansiedade e de depressão tiveram consistência interna de 0,68 e 0,77, respectivamente. A correlação dos itens com as respectivas subescalas sugere que essas possuem validades convergentes, não discriminantes. Com ponto de corte 8/9, a sensibilidade e a especificidade foram 93,7% e 72,6%, para ansiedade, e 84,6% e 90,3%, para depressão. Na prática clínica, a utilização da HAD poderia auxiliar na detecção de casos de transtornos do humor que necessitam de tratamento.
