This paper deals with Ibn al-Sīd al-Baṭalyawsī´s commentary al-Iqtiḍāb, trying to show the peculiar way in which Ibn al-Sīd develops his own critique of Ibn Qutayba's controversial thesis on the relation between orthodoxy, falsafa and kalām.

    At the end of IX and beginning of the X century begins development and renaissance of the medicine called Arabic, and which main representatives were: Ali at-Taberi, Ahmed at-Taberi, Ar-Razi (Rhazes), Ali ibn al-Abbas al-Magusi (Haly), ibn al-Baitar, ibn al-Qasim al-Zahrawi (Abulcasis), ibn Sina (Avicenna), ibn al-Haitam (Alhazen), ibn Abi al-Ala Zuhr (Avenzor), ibn Rushd (Averroes) and ibn al-Nafis. Doctors Taberi, Magusi and Razi were born as Persians. Each of the listed great doctors of the Arab medicine in their own way made legacy to the medical science and profession, and left lasting impression in the history of medicine. Majority of them is well known in the West well and have their place in the text-books as donors of significant medical treasure, without which medicine would probably, especially the one at the Middle dark century, be pale and prosaic, insufficiently studied and misunderstood, etc. Abdullah ibn Sina (Avicenna) remained unsurpassed in the series of above listed. Close to him can only come Alauddin ibn al-Nafis, who will in mid-XII century rebut some of the theories made by Avicenna and all his predecessors, from which he collected material for his big al-Kanun fit-tibb (Cannon of medicine). Cannon will be commended for centuries and fulfilled with new knowledge. One of the numerous and perhaps the best comments-Excerpts is from Nafis-Mugaz al-Quanun, article published as a reprint in War Sarajevo under the siege during 1995 in Bosnian language, translated from Arabic by the professor Sacir Sikiric and chief physician Hamdija Karamehmedovic in 1961.

    Full Text Available The hadith explanation book of Sahih al-Bukhari written by Ibn Hajar Al-‘Asqalani, Fath al-Bari, is one of the most pupular books in Moslem ummah. Is widely used by Moslem scholars to meet the meanings of hadiths compiled by the imam al-Bukhari in his Sahih al-Bukhari. Fath al-Bari is considered significant to do the research on it in order to develop the science of hadith, mainly through the hermeneutic method. By using this method, the research questions are: 1. How does Ibn Hajar Al-‘Asqalani explain the matans (hadith texts of Sahih al Bukhari in connection with hermeneutic method? 2. What are the hermeneutic principles used by Ibn Hajar Al-‘Asqalani in his explanations of hadith? This research is expected to respond the research questions above so that it can be implimented the field of hadith in relation to develop hadith methodology. Finally, the research uncover that in his explanations of hadiths,  Ibn Hajar Al-‘Asqalani is oriented his world views to the classical Islam, the era of Prophet’s companions and their successors, the Salaf al-Salih. He does not express the Islamic world issues available in his time in his explanations of the hadiths. He is considered a normative ‘ulama since he is not influenced by the emerging cases situated his time in Egypt, Mecca and Madina. He tends to be textual to explain the matans of hadiths although to some extent he uncovers the historical contexts of the hadiths he explains. This is common for a muhadith  whose main jobs is to collect and narrate the whole data on Prophet's sayings, acts and permissions either on sanads (narrators or matans (texts.Keywords:  Fath al-Bari; sharh al-hadith; hermeneutik.

Ontological view regarding the interpretation that was never a logical consequence of the importance of the final carry was critical of the existing interpretation of the results so far, so it is legitimate to question whether Ahkâm al-Qur’ân is still relevant to the demands of his time or not? Whether in it there is coercion-coercion and preconceptions-ideological Ibn al-‘Arabî or not? Given, Ahkâm al-Qur’ân is reproduced in the 5th century AH, where the fight discourse between the schools of thought Islam was at its height.

    Full Text Available Ibn ‘Arabî is one of the prominent and authoritative thinkers on Islamic mysticisms. Among his starting and brilliant ideas is the unity of religions (wahdah al-adyân, one of the fundamental ideas of religious pluralism. The supporters of pluralism expose his opinion on the unity of religions intensely and consider any religions valid and true.This article examines further Ibn ‘Arabî’s thought on pluralism. Through critical analysis on his works, I find that positioning his thought on pluralism issue is a partial understanding of his complete views on such topic. The unity of religions as described by Ibn ‘Arabî is a system of belief which is closely related to the Prophetical tradition and not merely based on the speculative assumption of human-being. He formulated a parameter—to see whether a religion is true or not—which contains three principal dimentions: the divinity, prophecy, and devotion.

  12. Ibn al-Haytham and His Influence on Post-Medieval Western Culture

    Science.gov (United States)

    Falco, Charles

    Born in Basra in 965, but doing most of his work in Cairo's Al-Azhar Mosque, Ibn al-Haytham (Latinized as Alhazen or Alhacen) wrote nearly one hundred works on topics as diverse as optics, poetry and politics. For nearly four hundred years his treatment of a particular geometry of reflection from flat and curved surfaces has been known as ''Alhazen's problem,'' and today al-Haytham is primarily known for his writings on geometrical optics, astronomy, and mathematics. However, as I will discuss, with his landmark seven-volume Kitāb al-Manāzir [Book of Optics], published sometime between 1028 and 1038, al-Haytham made intellectual contributions that subsequently were incorporated throughout the core of post-Medieval Western culture. His seminal work on the human vision system initiated what remains an unbroken chain of development that connects 21st century optical scientists with the 11th century Ibn al-Haytham. The noted science historian, David Lindberg, wrote that ''Alhazen was undoubtedly the most significant figure in the history of optics between antiquity and the seventeenth century.'' Impressive and accurate as that characterization is, our recent discoveries show that it significantly understates the impact that al-Haytham had on areas as wide-ranging as the theology, literature, art, and science of Europe. Portions of this work was done in collaboration with David Hockney.

    Full Text Available While the philosophers have thought about the classification of sciences since the 9th century in Islam, the scholars who elaborate the classification of books depend on other categorisation. The comparison between al-Fārābī, Ibn Ḫaldūn on the one hand and Ibn al-Nadīm and Ibn al-Akfānī on the other hand shows the prominence given to the Islamic thouight and the Arab classical literature on the Hellenistic legacy. The unique catalogue of the madrasa preserved reflects the same choice. The practical thematic classifications deviate from the rational epistemology in favour of a subjective or cultural ranking.

    Full Text Available The purpose of this article is to share the discovery of the mystical songs of muslim poet Muahmmud Ibn Al-Mahad. His poems disclose our poetic and mystical ancestral wealth, since the Muslim legacy, as well as the Greek and Hebrew,are part of our civilization matrix. The uruguayan poet Saúl Ibargoyen through the narrative identity of Al-Mahad, whom unveils as one Other on himself, has configured a very special kind of poetic mirror, close to a palimpsest sui géneriswhere we find the signs of an eternal scripture, which approach us to the Beloved woman’s beauty and the desert as images of the mystical experience. Inthe Al-Mahad’ songs we find out the profound traces of the well-known Sufi poet Yalal ad-Din Muhammad Rumi, who expressed in his verses the union with his beloved (tawhid the Perfect One. Also we perceive on his poems the delicate fragrance of Ibn ‘Arabî, called al Shaykh al-Akbar, “The Great Master”, whogaves us the gift of the “unity of the divine Essence”. The Real Being is incomparable and transcendent, but unveils itself as divine manifestation (tajallí in allthings. Thus, Al-Mahad’s verses configure this relation between love and unity to express with all subtleness the passion for the Beloved woman, as we appreciate in this poem: “In the book came from the Highest, is written also the silence ofthe zeal that cross your heart. Love the Beloved woman with that silence and the book will have new words for you”.

    Full Text Available The Immortality of the people of hell and their eternal torment is one of the most important and complex debates, preoccupying religious scholars of different religions and sects. Each of them has taken a different way based on their intellectual principles of belief to solve this problem and the questions thereof, including how the immortality of the inhabitants of hell hellions and their eternal torment is consistent with the mercy and justice of God. How is it reasonable to endure infinite torment for limited and finite sins? Does a Merciful God, born a sinful slave forever in the fire of the hereafter? Or  is this not the case and He punishes the sinful people for a limited period of time, whether it is short or long, and then releases them from  torture and provides them with  comfort. There is a difference of opinions on these problems in the works of Ibn Qayyim Al- Jawziyyah Al-Ash͑ari and Allameh Tabataba’i, the Shiite philosopher and commentator.Ibn Qayyim addresses widely and systematically the issue of the immortality of the inhabitants of hell. In fact, he interprets immortality (khulūd as a long time, so that the long fire and scourge annihilate the evil from the souls that evil has mixed in their being.  In his viewpoint God has created human monotheist. If the monotheistic nature of the person is changed by vices, these vices and the corrupted nature can be changed by torment and fire. He quotes in his works the ideas of the believers in immortality in torment and criticizes and rebuts them. Stating so many arguments, Ibn Qayyim Al-Jawziyya tries to deny the immortality and eternality in torment. Interpreting the verses of The Holy Quran on immortality of the inhabitants of hell in torment, Allameh Tabataba’i strongly asserts the immortality principle. He relates the happiness and misery, and good and evil among human beings to the development and appearance of the carnal states and habits they gained in the earthly

Philosophy as a method of rational thinking as the problem accused of infidelity. Ibn Rushd particpated in the arena of scientific debate with the brilliant idea of harmonizing between shari’ah and philosophy. For Ibn Rushd, the shari’ah and philosophy are not mutually contradictory. Instead, they are best friends which reinforce each other and strengthen the Islamic Pillars.

    Full Text Available There were various explications of the concept of tawhid presented by Muslim scholars in the past, especially among mutakallimun and falasifah, but most of them emphasized on the unity of essence, attribute activities. Ibn Taymiyyah is one of the most celebrated Muslim theologians and regarded by some as mujaddid or reformer on Islamic theological thought. His reformative thought could be discerned from his concept oftawhid, which is deemed unique and worthy of further studies. However, it is not only of his concept that he was regarded as reformer, but also his framework of theological studies. The method employed in this research is literary studies, yet it is also supported by historical, descriptive, inductive and critical analytical method. The finding of this research is that Ibn Taimiyyah’s concept of tawhidconsists of unity of God, unity of Allah worship and the unity of essence and attribute. The first means the belief existence of God as the Creator; the second is the manifestation of belief in the form worship by heart, speech and good deed; the last one is belief in the perfect attributes of Allah based on the Qur’an and Sunnah. He also emphasized that one who does not believe in these three kinds of tawhid, or believe only in the unity of God could not save from the Hell. Regarding the framework, Ibn Taymiyyah restricts that the theological discourses should commit to the Qur’an and Hadits, rely on rational capacity of man, rebuff kalam interpretation and prever revelation from reason.

    2002-11-01

    The subjects in this paper include Ibn Khaldoun's thoughts on writing, and their implications on today's medical writing. This paper discusses why people write, plagiarism, "Original" and "Copied' writings and where history writing goes wrong and how this can be applied to Medical writing today. The paper also discusses the nature of Science and Knowledge as viewed by Ibn Khaldoun, the anatomy of intelligence, types of thought processes, and effects of environment and craftsmanship on intellect. Ibn Khaldoun's definition of the "Medical" profession and its social standing is discussed as well as his emphasis of the importance of exercise, diet and climate on healthy living. Ibn Khaldoun has clear and advanced concepts on education and methodology of education. He emphasizes 3 stages of coaching, and the importance of travel in consolidating and clarifying knowledge attainment. He abhors coercion as a method of educating the young. Developing the interest of the pupil in the art he is studying, is thought by Ibn Khaldoun to be the central theme of good education. Relevance of all this to contemporary medical education is discussed. Ibn Khaldoun has fascinating ahead-of-time views on the influence of peer pressure and what is now known as "Emotional Intelligence" and he rejects the idea that intelligence is ethnically determined. Instead, he emphasizes the environmental, social and craftsmanship influence on human behavior. He stresses that the method of education has a lot to do with the "apparent" intelligence or "stupidity" of pupils.

  6. Ibn Rushd on God’s decree and Determination (al-qaḍā’, wa-l-qadar

    2006-12-01

    Full Text Available This article is based on Ibn Rushd’s chapter on God’s qaḍā’ wa-qadar, which adresses the question of predestination, as illustrative of a rationalistic approach that introduces philosophical views into an age-old religious debate. My aim is to present Ibn Rushd’s argument, which has unmistakable Aristotelian overtones; therefore, the harmonization of religion and philosophy implicit in his argument is one of the points I would like to explore in this paper. In the same way, I am interested in discussing whether Ibn Rushd’s proposed solution constitutes a middle way between two opposite positions and solves the perennial problem of determinism. The paper also discusses the issue whether he supports predestination, i.e., the view that events are predetermined by God before they happen.

    Este artículo se basa en el capítulo de Ibn Rušd sobre los atributos qaḍā’ wa-qadar de Allāh, que se ocupa del concepto "predestinación", como ejemplo de una aproximación racionalista que introduce conceptos filosóficos en un viejo debate religioso. Es mi propósito presentar el argumento de Ibn Rušhd que contiene inequívocas alusiones aristotélicas; por tanto, la armonización de la religión y la filosofía implícita en sus argumentos es uno de los puntos que trataré de explorar en este trabajo. Igualmente, estoy interesada en la cuestión de si las soluciones propuestas por Ibn Rušhd suponen un término medio entre dos posiciones enfrentadas y resuelven el eterno problema del determinismo. Este trabajo discute también si Ibn Rušhd defiende la predestinación, es decir, la cuestión de si los sucesos están predeterminados por Dios antes de que tengan lugar.

    Transmission of traditional knowledge over time and across culturally and historically related territories is an important topic in ethnopharmacology. Here, we contribute to this knowledge by analysing data on medicinal uses in two neighbouring areas of the Western Mediterranean in relation to a historical text that has been scarcely mentioned in historical studies despite its interest. This paper discusses the sharing of popular knowledge on the medicinal uses of plants between eastern Morocco and eastern Andalusia (Spain), focusing on one of the most useful plant families in the Mediterranean area: Lamiaceae. Moreover, we used the classical work of Ibn al-Baytar (13th century CE) The Compendium of Simple Medicaments and Foods as a basis to contrast the possible link of this information, analysing the influence of this historical text on current popular tradition of medicinal plant use in both territories. For data collection, we performed ethnobotanical field research in the eastern part of Morocco, recording current medicinal uses for the Lamiaceae. In addition, we systematically reviewed the ethnobotanical literature from eastern Andalusia, developing a database. We investigated the possible historical link of the shared uses and included in this database the information from Ibn al-Baytar's Compendium. To compare the similarity and diversity of the data, we used Jaccard's similarity index. Our field work provided ethnobotanical information for 14 Lamiaceae species with 95 medicinal uses, serving to treat 13 different pathological groups. Of the total uses recorded in Morocco, 30.5% were shared by eastern Andalusia and found in Ibn al-Baytar's work. There was a higher similarity when comparing current uses of the geographically close territories of eastern Morocco and eastern Andalucía (64%) than for eastern Morocco and this historical text (43%). On the other hand, coincidences between current uses in eastern Andalusia and the ones related in the Compendium

    Full Text Available The essay explores the range and function of the emulation (mu‘āraḍa in al-Andalus, taking as examples two odes of Ibn Darrāj al-Qasṭallī (d. 421/1030, dedicated to his first patron al-Ḥājib al-Manrṣūr and his last patron al-Mundhir b. Yaḥyā of Saragossa. The first is modeled on an ode of Abū Nuwās and a declared poetic contest, the second a silent overwriting of al-Mutanabbī’s ode on the battle of al-Ḥadath, summoning it as “the vocabulary of a second higher power” to invert a celebration of military victory into one of a wedding feast. The ode acted as an ideological strategy to defend the patron’s peaceful diplomacy with Saragossa’s two Christian neighbors in order to form a coalition against a third Christian party, and it responded to criticism by some Muslim contemporaries. Both emulations show the considerable freedom Ibn Darrāj took in developing the themes of his subtexts.

    Este artículo analiza las variedades y la función de la imitación literaria (mu‘āraḍa en al-Andalus a partir de dos poemas que Ibn Darrāj al-Qasṭallī (m. 421/1030 dedicó a sus mecenas al-Ḥājib al-Manrṣūr y al-Mundhir b. Yaḥyā. El primero de ellos imita un poema de Abū Nuwās, en competición poética explícita con el mismo. El segundo es una imitación no reconocida como tal del poema de al-Mutanabbī sobre la batalla de al-Ḥadath, que se invoca como “vocabulario de un segundo poder más elevado” para convertir la celebración de una victoria militar en la de una boda. al-Qasṭallī utilizó este segundo poema como estrategia ideológica para defender la diplomacia pacífica que su mecenas mantenía con dos vecinos cristianos de Zaragoza con los que formaba una coalición contra una tercera facción cristiana. Con él respondía a la crítica de la que esta política era objeto entre ciertos musulmanes. Ambas imitaciones muestran la considerable libertad que Ibn Darrāj se tomó a la

    2016-01-01

    This book provides the first critical edition of Ibn al-Haytham’s On the Shape of the Eclipse with English translation and commentary, which records the first scientific analysis of the camera obscura. On the Shape of the Eclipse includes pioneering research on the conditions of formation of the image, in a time deemed to be committed to aniconism. It also provides an early attempt to merge the two branches of Ancient optics—the theory of light and theory of vision. What perhaps most strongly characterizes this treatise is the close interaction of a geometric analysis of light and experimental reasoning. Ibn al-Haytham conducted his experiments in a systematic way by varying all that could be changed: the shape and size of the aperture, the focal length of the camera obscura, the distance and shape of the celestial bodies. This way, he achieved a thorough understanding. This work represents a decisive step in both the history of optics and the application of the experimental method that was just as effici...

The revolt of Ibn Qarhab is a well known issue that marks the island’s political transition from the Aghlabid sphere of influence to the nascent Fātimid caliphate in North Africa. Undoubtedly, the reconstruction of the revolt of Ibn Qarhab is based on a late and repetitive corpus of Arab-Islamic sources and, above all, on the irredentist and nineteenth century interpretation given by Michele Amari. The Andalusian source considered here, a passage from al-Muqtabis V of Ibn Ḥayyān, escaped from the mentioned historiographical networks as well as from the attention of current scholarship; it provides an opportunity to clarify some details and offer new interpretations of the event. The revolt of Ibn Qarhab can be interpreted as an informal quest for legitimacy obtained through alliances and contingencies that, unexpectedly, seems to move the island’s centre of gravity from the North African shore to the orbit of influence of the Umayyad emirate of al-Andalus¿Puede un detalle cambiar la historia de la Sicilia islámica?

    Idiopathic Ibn Sina, popularly known in the west as Avicenna;(980-1037 A.D.) was one of the foremost physicians and Islamic philosophers of his time. His chief medical work, Al-Qanun fi'l-tibb (The Canon of Medicine), is considered to be the most comprehensive medical encyclopedia ever written by an Arab physician. The book served as the final authority on medical matters in Europe for several centuries. It described some of the most illuminating medical thoughts that are relevant to modern medicine. In this article, we pay tribute to this great medieval Arab physician by providing a brief overview of his life and works, with special reference to his contribution to the advancement of medical science.

    Full Text Available Abstrak : Ibn Taymiyyah, meski dikenal sebagai tokoh panutan radikalis salafi yang anti pembaharuan dan alergi tasawuf, ternyata merupakan inspirator kaum modernis dan juga seorang sufi. Bagaimana mungkin seorang yang anti tasawuf   juga adalah seorang aktivis tasawuf ? Bagaimana posisi Ibn Taymiyyah seharusnya dipetakan?  Bagaimana pula sikapnya yang terlihat kontradiktif ini dapat dijelasakan? Dengan mengkaji karya-karyanya dan mempertimbangkan pengalaman hidup Ibn Taymiyyah yang ditelisik melalui perspektif psikosufistik penulis akan menjawab persoalan tersebut. Tulisan ini menyatakan bahwa kritikan dan penolakannya atas jenis tasawuf tertentu (nazharī-falsafī didasarkan kerancuan dalam pemaknaan istilah dan paradigma yang berbeda dari objek yang dikritiknya. Ditunjukkan pula sikapnya menjelang kematian —dalam kondisi batin terkondisikan sedemikian rupa sehingga bukannya dipenuhi diskursus ilmiah, ia tenggelam dalam taqarub dan perhatian penuh kepada Allah dan mencapai puncak pengalaman sufistik, fana— kendatipun kontradiktif, tidak lain merupakan perkembangan dari kesadaran religiusnya.Kata kunci : radikalis salafi, dualisme, fiqh al-qulūb, neo-sufisme, anti tasawuf, ḥulūl, ittiḥād, waḥdat al-wujūd.Abstract : Ibn Taymiyya, despite being well-kown as a figure of salafi-radicalists which are anti-reformism and oppose tasawuf, in fact is an inspiring figure for some modernist Muslims and is a sufi. How could it be possible for someone who criticizes tasawuf to be a sufi? How should Ibn Taymiyya be placed correctly in this regard?  How could his contradictive attitude be explained? These questions will be discussed in paper through a careful study of his works and by investigating his life-experience from a psycho-sufistic perspective. This paper argues that his criticism to certain kind of tasawwuf, i.e., the naẓarī-falsafī, is often based on confusion in understanding terms and departs from different paradigm used by

    2015-06-01

    Full Text Available The philosophical treatise known as Kitāb al-ḥadā’iq is generally ascribed to the 12th century Andalusian author Ibn al-Sīd al-Batalyawsī, although this attribution is sometimes contested. This paper offers a new interpretation of the title, textual history, authorship, sources, and literary genre of this treatise, on the basis of new textual evidence, a reexamination of known evidence, and a comparison between the treatise and Batalyawsī’s works. The conclusions of this study are first, that Kitāb al-ḥadā’iq was not the treatise’s original title, and therefore it should be renamed Kitāb al-dawā’ir; second, that Kitāb al-dawā’ir was originally part of (one of the versions of Batalyawsī’s Kitāb al-masā’il; and third, that the textual and stylistic similarities between this treatise and Batalyawsī’s other works prove the authenticity of the treatise’s attribution to Batalyawsī. In addition, new findings regarding Batalyawsī’s use of formulas from the Rasā’il Ikhwān al-Safā, in Kitāb al-dawā’ir and Kitāb al-masā’il provide further evidence for the deep impact of the Ikhwān on Batalyawsī’s thought, as well as for the close connection between Kitāb al-dawā’ir and Kitāb al-masā’il. This connection is further highlighted according to the attribution of both treatises to the genre of questions and answers in Arabic literature. The evidence gathered in this paper supports the claim that Batalyawsī’s Kitāb al-dawā’ir should be seen as an integral part of his literary oeuvre, as well as of Andalusian philosophical literature in general.Generalmente el tratado filosófico conocido como Kitāb al-ḥadā’iq se asocia al autor andalusí del siglo XII Ibn al-Sid al-Batalyawsī, aunque esta atribución ha sido discutida en ocasiones.

    Full Text Available The trial of Ibn al-Khaṭīb has left its mark on history because of the personality of the accused. Most scholars in the past have thought that his accusation and subsequent trial on religious grounds were no more than excuses intended to bring about his death, as a trial for high treason would, for various reasons, not have been possible. For this he had to be accused of crimes against religion as this was the only sure way of mounting a successful case against him. The accusations analysed here are taken from a variety of sources including Al-Marqaba al- 'ulyā and the works of al-Maqqarī, some of which have not been translated before. We notice procedural irregularities in the course of the trial, but both in Granada and in Fez the focus is on the zindīq who is finally condemned to death.

    El proceso de Ibn al- Jaṭīb ha pasado a la historia debido a la personalidad del inculpado. La mayoría de las opiniones coinciden en declarar la acusación y el proceso como un simulacro para conseguir su muerte, pues la acusación de alta traición, por las circunstancias que incidieron en el caso, no iba a conseguir el objetivo propuesto. Por esta razón se buscaron otros motivos con que inculparle y que permitieran perseguirlo y condenarlo en cualquier parte del Islam, por eso estas acusaciones sólo podían responder a delitos de lesa religión. Y se encontraron. Las acusaciones que se analizan en este trabajo figuran en varios textos, en al-Marqaba al-'ulyà y en las obras de al-Maqqarī, algunos de ellos no traducidos hasta ahora. En el desarrollo de las actuaciones se observan irregularidades procesales, pero tanto en Granada como en Fez, la condena se centra en la figura del zindīq cuya sentencia final fue la pena de muerte.

    Full Text Available Al-Qādī al-Nu,mān b. Muhammad was the most outstanding and prolific Fātimī scholar and the founder of Ismā,īlī jurisprudence. In his epistle “The eloquent clarification for the refutation of Ibn Qutayba”, still in manuscript, al-Nu,mān engaged in a heated atttack on Ibn Qutayba, who had lived a century earlier. The epistle was probably composed in the time of al-Mu´izz at the request of an anonymous tutor of the caliph’s sons. Al-Nu´mān’s purpose was to refute Ibn Qutayba’s assertion in the introduction to his famous Adab al-Kātib, acording to which it was enough for the kuttāb, the civil servants of the state, to memorize a number of simple legal formulas in order to perform their duties, without the need to learn the lengthy dissertations of the fuqahā’ or doctors of law. Al-Qādī al-Nu´mān, who was himself a famous faqīh, dedicates his epistle to proving that in fact without these long dissertations the law could not be properly applied. He refers to each legal formula mentioned by his oponent in Adab al-Kātib and shows how applications of the law should be based on the authority of the Imāms of the Ahl al-Bayt, the family of the Prophet Muhammad. At the same time he refutes various Sunnite legal perspectives on these same issues.

    Al-Qādī al-Nu´mān b. Muhammad es el más destacado y prolífico de los estudiosos fatimíes y el fundador de la jurisprudencia ismā´īlí. En su epístola “La clarificación elocuente para la refutación de Ibn Qutayba”, todavía en manuscrito, al-Nu,mān se lanza a una polémica en contra de Ibn Qutayba, que había vivido un siglo antes. Es probable que la epístola fuera escrita en la época de al- Mu´izz a petición de un tutor anónimo de los hijos del califa. En ella, al-Nu´mān se propone refutar la afirmación de Ibn Qutaybba, incluida en la introducción de su famosa obra Adab al-Kātib, según la cual era

    Full Text Available The purpose of this paper is to call attention to this book by Ibn al-Mu‘tazz, sometimes neglected, emphasizing its worth as a literary work and as a source for the study of humour in Arabic literature. Ṭabaqāt al-shu‘arā’ al-muḥdathīn is a very curious repository of biographies of ‘Abbāsid poets, with especial attention to the least known among them, but with personalities that might give occasion to tell a good story about their wit or their folly. So we have, at the same time that we receive information about some very famous poets, a remarkable record full of empathy and humour with tales of madmen, profligate people and rogues and scoundrels boasting of their trades.

    Tanto la poesía de Ibn al-Mu‘tazz, como su reflexión teórica sobre el nuevo estilo de poetizar que se inicia con los poetas ‘abbāsíes, han atraído la atención de críticos e investigadores, por la serena armonía de sus versos y la potente visualidad de sus imágenes y metáforas, y, en el caso del Kitāb al-badī‘, por tratarse de la primera obra dedicada a las figuras y tropos que caracterizan la poesía de los poetas postomeyas. Sin embargo, su antología sobre los poetas muḥdaṯūn ha quedado relegada a la posición ancilar de repositorio de nombres de poetas, fundamentalmente menores, de la época ‘abbāsí. En este artículo intento una lectura menos utilitaria de las Ṭabaqāt al-Šu‘arā’ al-muḥdaṯīn para destacar su calidad como obra literaria y, sobre todo, su interés para la historia del humor en la literatura árabe, pues su autor refleja en ella su curiosidad por personajes excéntricos, ridículos o marginales, que sólo se salvan de la condena absoluta por su pasión por la poesía.

    Full Text Available As a continuation of previous studies about the reception of Rasā’il Ikhwān al-Ṣafā’ in al-Andalus, this paper argues that it was common among Andalusī scholars of the Middle Ages to credit the astronomer Maslama al-Majrīṭī (d. 395/1004 or shortly thereafter not only with the authorship of Rutbat al-ḥakīm and Ghāyat al-ḥakīm – now both correctly ascribed to Maslama Ibn Qāsim al-Qurṭubī (d. 353/964 – but also with the entire encyclopaedic corpus of the Rasā’il. The first part of this article seeks to explain the series of successive confusions by which these three works came to be identified as forming three steps of a philosophical ladder and how this trilogy then came to be attributed to the scientist al-Majrīṭī. The second part focuses on two biographical notes found on the title pages of two manuscripts of the as-yet-unedited Rutbat al-ḥakīm. In addition to providing supplementary evidence for the spread of this misconception among medieval scholars, these documents also offer valuable and sometimes unique information about the two Maslamas, their respective writings and entourages, as well as the widespread circulation of the Rasā’il across the Peninsula. The edition, translation and commentary of these two biographical notes are here provided for the first time.

In expounding this law I have chosen the text of jurist-author of this School, Ibn al-Humâm (d. 861/1457 which offered a mere document for the subject-matter. The analysis in this essay exposed that Hanafi juristic conception considered the act of apostasy not a creedal but a political offence. Thereof the ratio legis (‘illa of death penalty imposed to the apostate (murtad is not his commitment of disbelief (kufr but his renouncement of the social, legal and political authority and system of the state and abandoning his membership of Muslim community after once accepted it. Consequently he has been accounted as a potential threat as a warring enemy to the survival of the Muslim community and its state. I understand that the jurists did not give the state legal authority to interrogate and punish the disbelief of its subjects. Belief of the individual rests between him and God.

    The Arabic physician 'Abd al-Latĭf ibn Yŭsuf al-Baghdădĭ, lived at the crossroads of the twelfth and the thirteenth century. His unbridled curiosity and his unquenchable thirst for knowledge of any kind brought him to far-away countries and regions and put him in contact with all sorts and conditions of people. The great Egyptian famine of the years 1200-1202 enabled him to study and examine thousands of human cadavers and skeletons at first hand. This led to a new understanding of the anatomical structure of the human body, and rejected the more or less antiquated ideas of the Greek doctor Galen of Pergamum. However, 'Abd al-Latĭf's vision was granted only a short life. After his death, his discovery sank into oblivion and as a consequence it was never again mentioned in Arabic medical manuals. From then on the Arabic physicians once more referred to the anatomical data which were developed and taught by Galen. Relatively few specimens of his remaining medical work were preserved for posterity. However, his Book of the two advices (or: K. al-Nasĭhatain) is of the utmost importance as a source for the medical thinking and the medical treatment in the late twelfth and the early thirteenth century A.D. During the years following World War I, 'Abd al-Latĭf's name reappeared within the spiritualistic movement in England. He became known as Abduhl Latif the great Persian physician and acted as a control of mediums. Until the late sixties, he practised the art of healing as the head of a medical mission somewhere in the Spheres.

This text is an adaptation of Aristotelian and Platonic theories on love to the Islamic tradition, which is based on the Arab poetic tradition and the moral precepts attributed to Muhammad. It deals –from an ontological perspective– with the contemplation of beauty as an object of sensual affection, which is the origin of the ailment of love.

    Full Text Available This essay describes Ibn ‘Arabi’s comprehensive views, captured in his important Futuhat and Fusus, on the concept of wahdat al-adyan, the discrepancy of beliefs, and the Shari’ah as well as its juncture and its unity. Elaborated explanation in this paper is expected to result in a true understanding of this crucial issue, particularly the concept of religious pluralism in the discourse of Islamic studies. Ibn Arabi’ extensively  discusses religion in the sense of the “ideal” versus “historical” or “esoteric” versus “the exoteric”. Ibn ‘Arabi concludes that the absolute unity of religions may only occur within spiritual, ideal, or transcendental realm (or “esoteric”, which is beyond the formal form of religions. Hence, the transcendental unity of religions cannot be found in the formal form of religions nor in the shari’ah.[Artikel ini mengulas pandangan Ibn ‘Arabi’ mengenai wahdat al-adyan seperti dijelaskan dalam dua bukunya; Futuhat dan Fusus, dan perbedaan dan kesamaan antara iman dan shariah.

Heused a kind of poetic theme in his poems that lacks the privilege and typicality of agood poem because he imitated some poets like Emre'al- Qays, Tarafah Ibn al-a’bd,Khansa, Hassan Ibn Sabet al-Ansary, Ka’b Ibn Zuhayr, Aboo Tammam and Al-Motanabbi. Concerning the issue of repetition, he made use of a large number ofrepetitive meanings in his poetic works, an example of which is the prophetMuhammad’s praise containing repetitive words and terminology. The eulogy of thekings and rulers of his time is also among some of his other repetitious works.However, there are some literary terms which are not authorized to be included inIbn-Nubatah’s poems, examples of such terms as syntax, prosody and some otherterms like dignitaries, hadith and Sufi terminology which Ibn-Nubatah used in hispoems. Ibn-Nubatah used the Quran and Hadith in his poetic works as well, which isa kind of citation indicative of a sort of religious concept in his poetic works becausereligious concepts have special dignity and value for him, so the poet had to payspecial attention to the demands and wishes of the public in his poetry. A largenumber of immoral contents can also be seen in his works. An attempt has been madein this article to examine such issues in the greatest poet’s poetry of that time, SheikhJamal Al-din Ibn-Nubatah.Key words: Ibn-Nubatah, Poetic style, repetition, imitation, deterioration

    Full Text Available  Abstract A part of Muslim philosophers’ studies is allocated to music. They categorize music as a sub-branch of mathematical sciences and investigate it scientifically, not artistically. Al-Musighi al-Kabir by al-Farabi and Javame’ Elm al-Musighi by Ibn Sina are among the most important works in this regard. Under the general category of music, they also allocate a section to the music of poem and investigate it scientifically. Their ideas about the music of poem are similar to as well as different from the ideas of prosodists. This article aims to study their ideas about the music of poem briefly. The first section is allocated to the issue of rhythm in verbal arts and it is shown that our philosophers consider two kinds of rhythm: quantifiable and not quantifiable. The first one exists in poem and the second one is in non-poetic language. Also they define certain characteristics for each of these rhythms. Quantity, the equality of cadences, provoking admiration and having distant returns are the features of poetic rhythm, whereas regular join and separation, similar endings, symmetry of sentences with regard to length, agreement and similarity of symmetrical words regarding movements, pauses and numbers of such words, appropriate usage of music-creating devices such as puns, alliterations and parallelisms are among the features of non-poetic rhythms. The significance of rhythm in poem and its status is another issue investigated in this article and it is shown that music and mimesis are two necessary elements that poem is made simply by the presence of them and the fundamental matter in the music of poem is “proportion”. Also it is shown that such matter is the basis of meters and prosodies. Our investigation shows that musical sounds and poetic meters are following the same system. Under other issues such as “Tanghim” it is shown that, by creating such terms, philosophers try to show that the factor of sound

  12. Did Ibn Sina Observe the Transit of Venus of 1032 CE?

    Kapoor, R. C.

    2012-09-01

    The Persian polymath Abu Ali ibn Sina (980--1037 CE), known to early Western sources as Avicenna, records that ``I say that I saw Venus as a spot on the surface of the sun''. This statement has been quoted, for example, by Nasir al Din al Tusi (1201--1274 CE). A Transit of Venus indeed took place during ibn Sina's life time, that is on 24 May 1032 CE. Did ibn Sina see this Transit or did he merely see a sunspot? The question was addressed by Bernard R. Goldstein in 1969 who concluded that ``this Transit may not have been visible where he lived''. Goldstein based his conclusion on the input provided by Brian G Marsden who in turn used mathematical tables prepared by J. Meeus in 1958. I have begun re-examination of the question by employing Fred Espenak's Transit predictions. Preliminary work shows that ibn Sina could indeed have obtained a glimpse of the Transit of Venus just before sunset from places like Isfahan or Hamadan. In other words, when ibn Sina said he saw Venus on the surface of the Sun, he probably meant it.

    Full Text Available Al-Mar’ah in the Qur’an was one of the main discussions among Muslim scholars and mufassirin, either seen from the position level or the role of their life. There are various studies about Al-Mar’ah in the Qur’an, also the term that is used for the context of mar’ah, including imro’ah and nisa’. Centuries ago, a large number of orientalist placed the Qur’an as the main study, which had never been separated from Jewish analogy. In fact, the most Muslims had been incited by their digression of thought. So, the prominent Muslim scholar and the contemporary mufassir, namely Ibnu’Asyur tried to straighten the anconformity assumption of orientalist in accordance to the Divine Revalation of God and Islamic teaching. Ibnu ‘Asyur’s thought about “imro’ah and nisa” according to the semantic Qur’an study based on dalil naqly and aqly on his tafsir. Thus, the interpretation is very oriented to the study of language depth. The term "imroah and an-nisa" according to the interpretation described by Ibnu 'Asyur has a different meaning between them. The term "imroah" has a more specific meaning than "an-nisa", also devoted to the two writing styles, ta' ta'nits or ta 'maftuhah ( which is more oriented to have the meaning "wife" or idzofah on the name of her husband which is written afterwards, and the writing with ta 'marbuthoh ( is used for 4 types of mar'ah they are barren women, old women, widow, and unmarried women. While for term "an-nisa" is a plural form of "imroah" which is dissaproved from the ashlu-l-kalimah, on the meaning women or adult female. The term “an-nisa” is a general word which has no purpose into specific meaning, but has a variety of meanings such as wives, mothers, women menstruated, and others according to the context of the sentence in the verses.

    Full Text Available Ibn Tufail as a scientist as well as an artist exposes the issues of human anatomy, autopsy, and vivisection and, thereby, could be regarded as a SciArtist. SciArt might be defined as a reciprocal relation between art and science. Followings are the kinds of these interactions: artistically-inclined scientific activities,science-minded artistic activities, and intertwined scientific and artistic activities. In their fictional treatises, Avicenna, Ibn Tufail, and Suhrawardi are traditional avatars of SciArt. This paper frames an account of SciArt, suggesting in detail Ibn Tufail’s work as a prototypical example, while Avicenna and Suhrawardi go beyond the scope of this paper. An instant of intertwined scientific and artistic activities strongly captivates the attentions to Ibn Tufail, describing human anatomy, autopsy, and vivisection in his Treatiseof Hay Ibn Yaqzan. Recognized as the first philosophical story, Hay Ibn Yaqzan depicts the whole philosophy of Ibn Tufail by the story of an autodidactic feral child a gazelle raised whom in an island in the Indian Ocean.

    High resolution electron microscopy (HRTEM) has unique advantages for structural determination of nano-sized porous materials compared to X-ray diffraction, because it provides the important structure factor phase information which is lost in diffraction. Here we demonstrate the structure determination of the first tri-continuous mesoporous silica IBN-9 by electron crystallography. IBN-9 has a hexagonal unit cell with the space group P6 3/mcm and a = 88.4 , c = 84.3 . HRTEM images taken along three main directions, [0 0 1], [11̄0] and [1 0 0] were combined to reconstruct the 3D electrostatic potential map, from which the tri-continuous pore structure of IBN-9 was discovered. The different steps of structure determination of unknown mesoporous structures by electron crystallography are described in details. Similar procedures can also be applied for structure determination of other porous and nonporous crystalline materials. © 2011 Elsevier Inc. All rights reserved.

    Full Text Available Ibn Khaldun, the North African versatile genius scholar of fourteenth century produced his famous work ‘al-Muqaddimah’ (the Introduction which is considered as one of the most sublime and intellectual achievements of the Middle Ages. It is a treasury of many sciences like history, psychology, sociology, geography, economics, political sciences,etc. He strongly argued in this book for low tax rate so that incentive to work is not killed and taxes are paid happily. His theory of taxation is an important contribution to economic thought. He is forerunner of the idea that high tax rates shrink the tax base because they reduce the economic activity. He is considered as the forerunner of Laffer’s curve. His ideas are comparable with those of supply-side economics that emphasized incentives and tax cuts as a means of economic growth.

    Many studies have proven atherosclerosis is an inflammatory immune disease. The spleen plays an important immune role in the human body. Splenectomy is often used in several clinical disorders; but recent studies have shown that splenectomy may be effective in the development of atheroma lesions. Ibn Sina or Avicenna was known as one of the greatest philosopher and physician in Islam and in Medicine. He is remembered for his masterpiece, The "Al-Qanun fi al-Tibb" or "Qanun of medicine". According to the "Al-Qanun fi al-Tibb", spleen as storage organ plays an important role in absorption and secretion of the black bile in the human body. Therefore any disruption in the function of the spleen can lead to various diseases such as atherosclerosis. Based on his description, it is clear that Ibn Sina first described the role of spleen in prevention of atherosclerosis. In this review, we discuss the Avicenna (Ibn Sina) aspect of atheroprotector role of the spleen. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

  5. Divine Emanation As Cosmic Origin: Ibn Sînâ and His Critics

    Directory of Open Access Journals (Sweden)

    Syamsuddin Arif

    2012-11-01

    Full Text Available The question of cosmic beginning has always attracted considerable attention from serious thinkers past and present. Among many contesting theories that have emerged, that of emanation was appropriated by Muslim philosophers like Ibn Sînâ in order to reconcile the Aristotelian doctrine of the eternity of matter with the teaching of al-Qur’ân on the One Creator-God. According to this theory, the universe, which comprises a multitude of  entities, is generated from a transcendent Being, the One, that is unitary, through the medium of  a hierarchy of  immaterial substances. While the ultimate source is undiminished, the beings which are emanated are progressively less perfect as they are further removed from the first principle. The process is conceived as being atemporal and often compared to the efflux of light from a luminous body, or to water flowing from a spring. This metaphysical theory has enabled Ibn Sînâ to solve the vexed problem: given an eternally existing world and one eternally existing God, how can the two necessarily co-exist without having the perfect, simple unity of God destroyed by contact with the multiplicity of material things? The following essay delineates and evaluates both Ibn Sînâ’s arguments as well as the counter-arguments of  his critics.

    Full Text Available Abstrak : Ibn ‘Arabi menawarkan kerangka pikir yang unik dalam menjelaskan struktur ilmu. Epistemologinya bersandar pada prinsip kesatuan wujud, dan bahwa semua pengetahuan adalah berasal dari Wujud yang dimiliki oleh Wujud melalui penampakan Dirinya. Manusia merupakan cermin dari penampakan Diri tersebut, yang di dalamnya terdapat satu fakultas sebagai pusat pengalaman manusia, yaitu hati (qalb. Melalui interaksi dengan pikiran, refleksi dan imajinasi, Ibn ‘Arabi menawarkan model epistemologi yang kokoh yang menjelaskan kerja pikiran dalam menciptakan keyakinan terhadap Tuhan. Ia (The Real hadir dalam tataran potensi tertinggi manusia, sebagaimana Ia hadir setiap saat dalam hati, pada kondisi yang disebut sebagai maqam yang tak bermaqam. Jika pendekatan post-modern sangat menekankan epistemologi yang memperkuat status multiplisitas ontologis mereka, ada paradigma yang berkembang yang mengusung visi kemanusiaan yang utuh melibatkan kesatuan tubuh, pikiran dan ruh. Epistemolgi Ibn ‘Arabi lah yang sanggup mewakili perkembangan ini dan merumuskan struktur yang abadi dan proses yang mencakup kecakapan manusia untuk sadar dan merasakan.Kata kunci : Kehadiran, Hati, Kesatuan wujud Abstract : Ibn ‘Arabi offers a unique framework for explaining the structures of knowledge. His epistemology is referenced within the Oneness of Being (wahdāt al-wujūd, and all knowledge is ultimately the knowledge that the Being has of Itself through Its own self-disclosure.

    Full Text Available This article discusses the views of the teologian and legal scholar Ibn Ḥazm of Cordoba (d. 456/1064 on homosexuality. Although reference is made to his literary work Ṭawq al-ḥamāma, which is rich in anecdotes on homoerotic attraction, the article focuses on Ibn Ḥazm's multivolume legal tract Kitāb al-Muḥallā, a work written from a Ẓāhirī, or literalist perspective. A step-by-step analysis of Ibn Hazm's legal reasoning on homosexuality, both male (liwāṭ and female (siḥāq is provided, and comparisons with the views of other jurist, especially Mālikis, are made. Unlike his Mālikī contemporaries, Ibn Ḥazm holds that homosexuality is not to be equated with fomication (zinā, which incurs the death penalty. Instead, he advocates a relatively mild punishment of up to ten lashes for homosexual practices, based upon his idiosyncratic interpretation of the revealed sources which is illustrated here. Although Ibn Ḥazm is believed by some modem authors to have had homosexual leanings himself, he categorically condemns sexual contacts between members of the same sex as immoral and sinful, and believes that homosexuals should be reformed.

    Full Text Available Abstract : To establish an argumentation for the existence of God is properly the most crucial as well as complicated effort in the life of religion and faith of human being. There are various approaches and methods have been applicated to reach it by theologians, thinkers, and scientists, including philosophers with their demonstrative-philosophical method. Some arguments which were initiated by Aristotle are ones of the most popular and have been adopted and improved as well by many thinkers and philosophers after him, some arguments which proposed by Ibn Rusyd and St. Thomas Aquinas with some modifications and improvisations are the best examples of it. In the case of elaboration and analysis toward those arguments for the existence of God, this article attempts to compare between metaphysical thought of Ibn Rushd (well-known in the West as Averroës and St. Thomas Aquinas. There is no doubt that both are Aristotelian in their philosophy. Therefore, to seek the similarities and differences, and to analyze the influence of Aristotle on their modes of thought, especially in argumentation for the existence of God, are an urgent point in the way to find more stronger and relevant arguments.Keywords: argument of creation (dalīl al-ikhtirā`, teleological argument (dalīl al-‘ināyah, unmoved mover, prime cause, influence, parallelism.Abstrak : Menggagas argumentasi tentang eksistensi Tuhan sejatinya merupakan upaya yang paling krusial sekaligus pelik dalam kehidupan beragama dan kepercayaan umat manusia.

Does Islam follow a view of absolutism in the decision making process. How does representative institutions decision become a constitutional decision. What is the form of consultation can be done to get the best decision. Almost all forms of Islamic political thought agree to make syûrâ (consultation system, consulting as a tool to create a state decision. Yet, the debate is on the problems that can be decided or determined through the mechanism of the syûrâ. For Ibn Taymiyyah, people are the main owners of state power. Determination of choice for power players and the way of power are completely in the hands of the people. They are the owners of the leadership in general. They are entitled to elect and dismiss the leader, as they also decide the broad outlines of state policy that must be done by him. Moreover, the authority outlines is not on the leader, but on the whole people. However, the syûrâ is not like the promoted Western liberal democracy. It has its characteristics, traits and principles.

    [Melalui kerangka teori sosiologi modern serta metode penafsiran teks secara historis-sosiologis, penelitian ini berusaha untuk menjelaskan pemikiran sosial Ibn Khaldun tentang masyarakat badui dan ḥaḍar. Ide Ibnu Khaldun tentang masyarakat dapat dilihat pada konsepnya mengenai dua masyarakat ini beserta solidaritas sosial mereka, dengan karakteristik masing-masing. Masyarakat nomaden yang identik dengan masyarakat badui memiliki struktur sosial dan spesifisitas dengan kecenderungan pada kebajikan, ramah, dan keseragaman; sementara masyarakat ḥaḍar memiliki struktur dan kekhasan sosial seperti pluralis, pragmatis, dan hedonis. Dalam hal gaya hidup, masyarakat badui tampak lebih dinamis daripada ḥaḍar. Cara hidup masyarakat badui ditandai dengan terus berpindah dari satu tempat ke tempat lain, dan ini membuat komunitas ini cerdas dalam merumuskan visi, misi, program, dan sasaran yang ingin dicapai dalam hidup. Spesifisitas badui tercermin dalam kesiap-siagaan mereka, satu hal yang tidak terlihat dalam komunitas ḥaḍar. Sementara itu, dengan kemakmuranya, orang ḥaḍar sibuk dengan aktivitas perkotaan dan pembangunan masyarakat sipil. Ibn Khaldun telah berusaha untuk memahami manusia dan keberadaannya secara individu ataupun sosial melalui ‘ilm al-‘umrān. Metodologi sosialnya mencerminkan pandangannya secara keseluruhan melalui pengamatan realitas sosial secara komprehensif. Penulis berpendapat bahwa metodologi sosial Ibn Khaldun yang menggabungkan data dan fakta sosial dengan agama bisa menjadi referensi dan contoh pendekatan yang komprehensif. Ide penting Ibnu Khaldun lainnya adalah tentang perkembangan kecerdasan masyarakat yang meliputi tiga tahap: tamyīzī, tajrībī, dan naẓārī.

    Khan, Murad Ahmad; Raza, Fauzia; Khan, Iqbal Akhtar

    2015-01-01

    Ibn Sina, the most eminent Muslim physician, illuminative philosopher, great thinker and a versatile genius is regarded as the "Father of Early Modern Medicine" and as the "Father of Clinical Pharmacology". The "Kitab al-Qanun fi-al-Tibb", commonly known as the "Canon Medicinae" is the most important of his medical works and, at the same time, the most carefully preserved treasury both in original Arabic and in the initial Latin version. It is the final codification of all Greco-Arabic medical thoughts up to his time, enriched and modified with his own scientific experimentations and independent observations. It is considered "The First Textbook of Medicine on the Earth". The "Canon" surpassed the books of Hippocrates and Galen and remained supreme for more than six centuries, in the West. Ibn Sina described "Seven Doctrines" for Preservation of Health, based on the Mudawa Salookia, in his magnum opus. The roots of these principles can be traced, to a significant extent, to Egyptian Medicine, Hebrew Medicine, Greek Medicine, Roman Medicine, Traditional Chinese Medicine, Ancient Persian Medicine, Ayurvedic Medicine (Hindu Medicine) and Islamic Medicine.

Various problems have been addressed through the library research method. The study produced several findings: First, human beings according to Ibn Khaldun as a creation of God with all the potential fitted to the five senses and intellect become intellect. The purpose of education opens the mind and maturity of the individual to the advancement of religious, industrial and social system. Material teaching is as educational planning. The method is to advocate phasing method, repetition, widya-tours and training (practice. Secondly, according to John Dewey man is a subject that has the ability, strength, personality, and existence who are capable of changing realities. The goal of education is only to gain happiness in the world life. The method of education is including problem solving, learning by doing and discipline. Third, the thought of Ibn Khaldun is much more religious because it is influenced by its control logic in religious knowledge, so that emphazises more on human spirituality in building civilization. While John Dewey is more radical and extreme, He proposed progressive education which strives against traditional teaching authority. Both Ibn Khaldūn dan Dewey are arise from inhuman socio-cultural environment and recognize the existence of human existence with nature and humanity impulse.

    Our objective was to evaluate the completeness of the United States National ALS Registry (Registry). We compared persons with ALS who were passively identified by the Registry with those actively identified in the State and Metropolitan Area ALS Surveillance project. Cases in the two projects were matched using a combination of identifiers, including, partial social security number, name, date of birth, and sex. The distributions of cases from the two projects that matched/did not match were compared and Chi-square tests conducted to determine statistical significance. There were 5883 ALS cases identified by the surveillance project. Of these, 1116 died before the Registry started, leaving 4767 cases. We matched 2720 cases from the surveillance project to those in the Registry. The cases identified by the surveillance project that did not match cases in the Registry were more likely to be non-white, Hispanic, less than 65 years of age, and from western states. The methods used by the Registry to identify ALS cases, i.e. national administrative data and self-registration, worked well but missed cases. These findings suggest that developing strategies to identify and promote the Registry to those who were more likely to be missing, e.g. non-white and Hispanic, could be beneficial to improving the completeness of the Registry.

Tunis ca. 996-1048 and an analysis of the contents of his Urjūza fī aḥkām al-nuŷūm which are compared to those of his better known Kitāb al- Barī‘ fī aḥkām al-nujūm. The conclusion is that both works are independent and that the Urjūza is not a summary of the Barī‘. The paper continues with biobibliographical data of the historian, mathematician and astrologer Ibn Qunfudh al-Qusanṭīnī (1339-1407, who is the author of a commentary of Ibn Abī l-Rijāl’s Urjūza dedicated to Abū Bakr b. Abī Mujāhid Gazī Ibn al-Kās, vizier of the Merinid sultans Abū Fāris (1366-1372 and Abū Zayyān (1372-1374. The work was probably written during the latter’s brief reign and before 1375, the date in which the dedicatee was exiled to Majorca. The work continues with an analysis of the contents of the commentary, the sources quoted, the astrological techniques used both by Ibn Qunfudh and by Ibn Abī l-Rijāl, and the use by the commentator of a set of astronomical tables derived from the zīj of Ibn Isḥāq. We find, finally, a detailed commentary of the horoscopes contained in Ibn Qunfudh’s work which includes one corresponding to the vernal equinox of the year 571 AD, in which there was a conjunction of Saturn and Jupiter which announced the arrival of Islam. There are eleven more horoscopes (two of them published previously which constitute an astrological history of Merinid Morocco between 1348 and 1366. Concerning the nine horoscopes analysed here, in six of them it has been possible to identify the subject or the event motivating the prediction, while three remain unidentified.

    Full Text Available Shaykh Muhieddin Ibn Arabi reçut une éducation religieuse tant par ses oncles, qui embrassèrent la voie initiatique que par les maîtres spirituels qui lui autorisèrent et le dirigèrent ainsi dans cette retraite spirituelle, "khalwa", qui lui permit le dévoilement de la connaissance divine. Le comportement spirituel acquis par Ibn Arabi, à travers les enseignements des maîtres, peut être synthétisé dans la présence spirituelle scrupuleuse, dans la sollicitude, dans l’abandon confiant en Dieu et dans la pleine conscience que Dieu se révèle à tout instant.

    2003-06-01

    Full Text Available This article aims at elucidating Abraham Ibn Ezra's (ca. 1089 - ca. 1167 opinion about the creation of the supra-lunar world. A major and striking feature of Ibn Ezra's approach is that he did not find it convenient to address this issue, intimately related to the nature of the celestial bodies, in his astronomical or astrological treatises, but rather in his biblical commentaries. Therefore, we propose to concentrate our efforts on the meticulous study of the two commentaries which Ibn Ezra wrote on Genesis 1,14. As this verse focuses on the account of the creation of the heavenly bodies, we have assumed that the elusive Ibn Ezra could not have avoided revealing his view, or, at least, that we should have left some significant hints from which we may uncover his genuine opinion about the creation of the supra-lunar world.

    El propósito de este artículo es averiguar la opinión de Abraham Ibn Ezra (ca. 1089 - ca. 1167 sobre lo relacionado con la creación del mundo supralunar. Una característica fundamental dei modus operandi de Ibn Ezra es que, si buscamos información acerca de su opinión sobre la creación del mundo, tanto sublunar como supralunar, no la hallaremos en sus tratados científicos astronómicos o astrológicos, sino precisamente en sus comentarios bíblicos. Por lo tanto, la metodología más adecuada consistirá en concentrar nuestros esfuerzos en el estudio meticuloso de sus dos comentarios a Génesis 1,14. Dado que este verso bíblico tiene como objetivo principal el relato y la descripción de la creación de las luminarias, pensamos que en ambos comentarios Ibn Ezra no pudo haber eludido dar su verdadera opinión -o al menos dejar alguna pista significativa- sobre la creación del mundo supralunar.

    The Medical Poem ("Al-Urjuzah Fi Al-Tibb") of Ibn Sina (Avicenna, 980-1037), is the subject of this primary-source study evaluating its scientific value, poetics and pedagogical significance as well as assessing its role in the transmission of medical knowledge to Medieval Europe. In addition to one original manuscript and two modern editions, the English translation by Krueger was also studied. Ibn Sina's poem on medicine consisting of meticulously classified 1326 verses, can be considered as a poetic summary of his encyclopedic textbook: The Canon of Medicine; hence its popularity in the East then the West as a tool in the process of transmitting medical knowledge from master to student. Since first translated by Gerard of Cremona (1114-1187) in the middle of the 12(th) century, the Latinized poem was frequently published in Medieval Europe either independently or combined with the Latinized Canon of Medicine or with the Articella; the famous collection of Greco-Roman and Latinized Arabian medical treatises in use in the universities of Salerno, Montpelier, Bologna and Paris up to the 17(th) century. The study of the Krueger's English edition revealed few places where the full meanings of the original Arabic text were not conveyed. A list of those places is given together with the suggested corrections.

    Sphygmology is a 2000-year-old method that is still used in some traditional medicine systems, mainly Iranian, Chinese and Ayurveda. Ibn Sina is one of the most popular physicians in the history of Sphygmology, who had made great contributions to this method, but few meticulous studies have been made on his concepts. In this article, his standpoints on Pulsology are studied. Ibn Sina has mentioned 10 parameters for pulse palpation, and 13 compound pulses, as well. Besides, some pulse patterns applicable for differentiating similar diseases have been introduced. Nowadays some concepts on pulse patterns, such as pulse change in sleep and pregnancy have been studied; but unfortunately many of the ideas on Pulsology have not yet been examined. Sphygmology, as an accessible and inexpensive means, having a substantial diagnosis yield, has been accepted by the people since its rise, and its development over centuries ago. Although some new instruments have been innovated, which can measure different parameters of pulse, yet sphygmology can be one of the most commonly usable diagnostic methods in future, not only applicable by cardiologists but also by all the physicians.

    The aim of this study was to describe epidemiological, cytologic and immunophenotypic aspects of acute leukemias (AL) in children diagnosed at IBN SINA University Hospital Center and to determine the concordance between cytology and immunophenotyping results. This is a cross-sectional study conducted in the hematology laboratory of IBN SINA University Hospital Center between June 2012 and May 2014. Among the 104 cases with diagnosed AL, 52% were boys with a sex-ratio H/F= 1.32, the average age was 5.7 years. The distribution of different types of AL was: lymphoid AL (LAL) (74%), myeloid (AML) (20.2%), biphenotypic AL (BAL) (65.8%). Among the LALs, 78% were classified as B LAL and 22% as T LAL. Clinical signs were mainly presented with tumor syndrome (73.1%), fever (61%) and hemorrhagic syndrome (50%). The most common blood count abnormalities were: thrombopenia (89.4%), anemia (86.5%), hyperleukocytosis (79.8%). The rate of peripheral and bone marrow blasts was statistically higher for LAL than for AML and BAL (p <0.001). The rate of relapse and mortality was 21.2% and 16. 3% respectively. Concordance rate between the results of cytology and of immunophenotyping was 92.7% for LAL and 82.6% for AML. Diagnosis of AL is always based primarily on cytology. Immunophenotyping allowed us to make a better distinction between acute leukemias. The management of paediatric AL is a major health problem which requires specialized care centers.

    In this review, we introduce the traditional uses of saffron and its pharmacological activities as described by either Avicenna in Book II, Canon of Medicine (al-Qanun fi al-tib) or from recent scientific studies. Modern pharmacological findings on saffron are compared with those mentioned in Avicenna's monograph. A computerized search of published articles was performed using MEDLINE, Scopus and Web of Science databases as well as local references. The search terms used were saffron, Crocus sativus, crocin, crocetin, safranal, picrocrocin, Avicenna and 'Ibn Sina'. Avicenna described various uses of saffron, including its use as an antidepressant, hypnotic, anti-inflammatory, hepatoprotective, bronchodilatory, aphrodisiac, inducer of labour, emmenagogue and others. Most of these effects have been studied in modern pharmacology and are well documented. The pharmacological data on saffron and its constituents, including crocin, crocetin and safranal, are similar to those found in Avicenna's monograph. This review indicates that the evaluation of plants based on ethnobotanical information and ancient books may be a valuable approach to finding new biological activities and compounds.

    The blood transfusion and haemovigilance service of the Ibn-Sina hospital in Rabat (Morocco) was created 1997. This unit manages the pretransfusional tests, distribution of blood products, traceability and haemovigilance. The objective of this study was to analyze, over a period of 12years, the traceability of blood products delivered in our hospital and the measures used to improve feedback information. This is a retrospective study conducted between 1999 and 2010. Traceability rate was calculated from the feedback of traceability forms supplied with blood products (number of blood products noted on traceability forms on the total number of delivered product). To improve traceability rate, several actions were undertaken: one-time training, awareness campaigns and call phones asking for feedback information. Between 1999 and 2010, the service has delivered 173,858 blood products. The average rate of traceability during this period was 13.4 %. Traceability rate varies widely over time (5.2 % in 1999, 15.5 % in 2010) and shows a maximum value of 27.2 % in 2005. Feedback information is lower in emergency departments than in medical and surgical services. Feedback information about traceability in Ibn-Sina hospital remains very poor despite the measures used. Other actions, such as continuous education courses, low enforcement and informatisation should be considered. Copyright © 2011 Elsevier Masson SAS. All rights reserved.

  12. Thinking about change: Ibn Khaldūn´s and his contemporaries Historical analysis and mentalities

    2011-06-01

    Full Text Available Starting from Ibn Khaldūn´s thoughts as expressed in the Muqaddima on change in history, on the use of analogy and comparison as instruments to make it recognizable and on the imperativeness of historical writing in the face of the great phenomena of change, the article proposes a reflection on this theme in the light of the history of mentalities. Ibn Khaldūn´s theoretical thinking, but also his different attitudes in the face of the on-going transformations in the societies with which he was familiar, are therefore compared with the mental attitudes of some other categories of his contempo-rary scholars, with particular reference to 8th/14th century Egypt. For example, the authors of Kutub al-bidaʻ and pilgrimage guides reacted in different ways towards the changes they perceived in both the religious and non-religious customs of the Moslem society examined in the framework of the mentalities and transformations which marked the historical period in which he lived.

    Stroke or cerebrovascular accident (CVA) is caused by a disturbance of the blood supply to the brain and an accruing loss of brain function. The first recorded observations were in 2455 BC and it has been studied intensely by ancient physicians throughout history. In the early medieval period, Ibn Sina (980-1025 AD) called stroke sekteh and described it extensively. Some of Ibn Sina's definitions and his etiology of stroke are based on humoral theories and cannot be compared with medical current concepts, but most of his descriptions concur with current definitions. This review examines the definition and etiology, clinical manifestations, prognosis, differential diagnosis, and interventions for stroke based on Ibn Sina's epic work, Canon of Medicine. The pharmacological effects of medicinal herbs suggested by Ibn Sina for stroke are examined in light of current knowledge. © 2013.

    Tinea capitis (TC) is a contagious infection that affects mainly children and teenagers. A retrospective study was realized at the mycology-parasitology department of the Ibn Sina hospital in Rabat, Morocco. The study includes 125 cases of TC. The mean age is 12.73 ± 11.61 year. The isolation of TC is dominated by two species Trichophyton violaceum 76 (60.8%) and Microsporum canis 27 (21.6%). Trichophyton verrucosum was isolated only in male and all of rural origin. In adults over 18 years, the most isolated species is T. violaceum (six cases) in females. For the last thirty years, the epidemiological profile of TC remains almost the same in Morocco.

  15. La figure historique d’Ibn ‘Abbâs

    2012-01-01

    Full Text Available ‘Abdallâh b. ‘Abbâs est l’une des hautes figures du savoir islamique constitué au premier siècle. Les diverses notices biographiques qui lui ont été consacrées dans les sources sunnites en témoignent à travers le portrait lisse et monochrome du Compagnon et du savant. Cependant, un autre portrait nous a été conservé, celui d’un homme partisan, au cœur de la mêlée qui oppose les différents clans de Quraysh dans la lutte pour le pouvoir. La figure dessinée par l’ouvrage édité sous le titre Akhbâr al-Dawla l-‘Abbâsiyya (ou quelques autres ouvrages du même genre échappe en grande partie à l’exemplum déshistoricisé des traditionnistes. Cet autre point de vue ne donne nullement à croire que l’auteur anonyme des ADA nous fournit une image plus authentiquement historique d’Ibn ‘Abbâs, mais il vient contredire la vision des religieux, ou celle des anthropologues, qui s’attachent à gommer l’accidentel dans le portrait stéréotypé. Certes, l’homme de chair et d’os, l’individu Ibn ‘Abbâs, nous échappe définitivement, mais sa figure historique peut-être pas. On peut, en effet, se demander si dans les informations rapportées par certains akhbâr, et qui relèvent de la recréation littéraire, ne se dissimule pas aussi la démarche réflexive de l’historien qui met en scène des faits en leur fournissant une explication. À la différence des traditionnistes qui ne se risquent dans le conflit que de façon allusive ou feutrée, les historiographes et leurs informateurs, des hommes souvent non répertoriés parce qu’ils n’appartiennent pas aux cercles de la riwâya, ne dissimulent pas les enjeux d’ordre historique. Quelques exemples empruntés aux ADA en sont donnés.

    Type Ibn supernovae (SNe) are a small yet intriguing class of explosions whose spectra are characterized by low-velocity helium emission lines with little to no evidence for hydrogen. The prevailing theory has been that these are the core-collapse explosions of very massive stars embedded in helium-rich circumstellar material (CSM). We report optical observations of six new SNe Ibn: PTF11rfh, PTF12ldy, iPTF14aki, iPTF15ul, SN 2015G, and iPTF15akq. This brings the sample size of such objects in the literature to 22. We also report new data, including a near-infrared spectrum, on the Type Ibn SN 2015U. In order to characterize the class as a whole, we analyze the photometric and spectroscopic properties of the full Type Ibn sample. We find that, despite the expectation that CSM interaction would generate a heterogeneous set of light curves, as seen in SNe IIn, most Type Ibn light curves are quite similar in shape, declining at rates around 0.1 mag day{sup −1} during the first month after maximum light, with a few significant exceptions. Early spectra of SNe Ibn come in at least two varieties, one that shows narrow P Cygni lines and another dominated by broader emission lines, both around maximum light, which may be an indication of differences in the state of the progenitor system at the time of explosion. Alternatively, the spectral diversity could arise from viewing-angle effects or merely from a lack of early spectroscopic coverage. Together, the relative light curve homogeneity and narrow spectral features suggest that the CSM consists of a spatially confined shell of helium surrounded by a less dense extended wind.

    Full text: Since the implementation of Law No. 00571 of 21 Chaabane 1391 on protection against ionizing radiation and its decrees 2: 2-97-30 and 2-97-132 28 October 1997, surveillance of workers has the subject of major regulatory developments in Morocco, including individual registration delayed for dosimetry. As part of optimizing the protection of medical personnel, a dosimetric study was performed for the first time at the national level, the Nuclear Medicine Service of the Ibn Sina hospital in collaboration with the National Center for Energy Sciences and Nuclear Techniques (CNESTEN). Dosimetric monitoring was conducted for 2 weeks with the use of passive thermoluminescent dosimeters, (GR200A), covering all categories of staff. The administration of samarium (β emitter with energy substantially higher than the energies encountered in conventional nuclear medicine) has been studied, given his first service. Other cases of people concerned our study: a pregnant woman doctor, whose exposure of the unborn child must be reduced as much as possible, and a woman from a private company, working without dosimeter, handles maintenance of premises. To control the conditions imposed on all activities requiring exposure to ionizing radiation, we evaluated the dose at the extremities of operators with the use of ring dosimeters (GR200A) and the dose on the ambient environment of staff (dosimeters ALNOR). This experiment has shown exposure levels below legal limits, without been negligible for certain post. The evaluation results equivalent doses manipulators justify the wearing of dosimeter rings as a complementary dosimeter in Nuclear Medicine service and a way of controlling the normal working conditions. Finally Monitoring ambient dosimetry showed that the environment is low radiation doses. Lessons learned from this study, for the protection of personnel are as follows: from the simple awareness of staff and means of optimizing radiation can maintain a dosimetry annual

    To determine whether race/ethnicity and socioeconomic status are associated with amyotrophic lateral sclerosis (ALS) mortality in the United States. The National Longitudinal Mortality Study (NLMS), a United States-representative, multistage sample, collected race/ethnicity and socioeconomic data prospectively. Mortality information was obtained by matching NLMS records to the National Death Index (1979-2011). More than 2 million persons (n = 1,145,368 women, n = 1,011,172 men) were included, with 33,024,881 person-years of follow-up (1,299 ALS deaths , response rate 96%). Race/ethnicity was by self-report in 4 categories. Hazard ratios (HRs) for ALS mortality were calculated for race/ethnicity and socioeconomic status separately and in mutually adjusted models. Minority vs white race/ethnicity predicted lower ALS mortality in models adjusted for socioeconomic status, type of health insurance, and birthplace (non-Hispanic black, HR 0.61, 95% confidence interval [CI] 0.48-0.78; Hispanic, HR 0.64, 95% CI 0.46-0.88; other races, non-Hispanic, HR 0.52, 95% CI 0.31-0.86). Higher educational attainment compared with socioeconomic status, birthplace, or type of health insurance. Higher rate of ALS among whites likely reflects actual higher risk of ALS rather than ascertainment bias or effects of socioeconomic status on ALS risk. © 2016 American Academy of Neurology.

  3. The roots and constructs of Ibn Khaldūn’s critical thinking

    Directory of Open Access Journals (Sweden)

    Salah Machouche

    2015-12-01

    Full Text Available Many current researches have sought to explore the thought and contributions of Ibn Khaldūn to the various disciplines of human knowledge including philosophy of history, historiography, politics, economics, and education. Little interest, however, is given to his contributions to the theory of critical thinking. This research investigates Ibn Khaldūn’s perspective on critical thinking and critique of intellectual disciplines while exploring its origin and dimensions. The research shows that Ibn Khaldūn’s critical thinking is essentially entrenched in the fundamental vision and origins of Islam, and reflective of the broad Islamic scholarship and the practices of Muslim scholars across the different religious and rational disciplines. What characterises Ibn Khaldūn’s contribution to the field of critical thinking is his ability to apply it across various fields of scholarship yet with a conscious attention to society’s dynamics, particularly the practical dimensions and implications of his theory of human society (‘umrān basharī.

  5. Controlled synthesis of the tricontinuous mesoporous material IBN-9 and its carbon and platinum derivatives

    Zhao, Yunfeng

    2011-08-23

    Controlled synthesis of mesoporous materials with ultracomplicated pore configurations is of great importance for both fundamental research of nanostructures and the development of novel applications. IBN-9, which is the only tricontinuous mesoporous silica with three sets of interpenetrating three-dimensional channel systems, appears to be an excellent model mesophase for such study. The extensive study of synthesis space diagrams proves mesophase transition among the cylindrical MCM-41, tricontinuous IBN-9 and bicontinuous MCM-48, and also allows a more precise control of phase-pure synthesis. On the other hand, rational design of structure-directing agents offers a possibility to extend the synthesis conditions of IBN-9, as well as tailor its pore size. Moreover, an unprecedented helical structure consisting of twisted 3-fold interwoven mesoporous channels is reported here for the first time. The unique tricontinuous mesostructure of IBN-9 has been well-replicated by other functional materials (e.g., carbon and platinum) via a "hard- templating" synthesis route. The obtained carbon material possesses large surface area (∼1900 m2/g), high pore volume (1.56 cm 3/g), and remarkable gas adsorption capability at both cryogenic temperatures and room temperature. The platinum material has an ordered mesostructure composed of highly oriented nanocrystals. © 2011 American Chemical Society.

  6. ‘Aṣabiyyah, Religion and Regime Types: Re-reading Ibn Khaldūn

    Directory of Open Access Journals (Sweden)

    Wahabuddin Ra’ees

    2004-12-01

    Full Text Available Ibn Khaldūn found a “causal determinative analytical tool” to explain development, progression and disintegration of ‘umrān (lit. culture. He argued that ‘umrān comes into existence as a result of five types of causes: (1 the “ultimate or first cause,” (2 final cause, (3 efficient cause, (4 formal cause, and (5 material cause. However, in Ibn Khaldūn’s scheme of analysis, the efficient cause of ‘umrān and political institutions consists of two factors: (1 ‘aṣabiyyah and (2 religion. Ibn Khaldūn believed that a meaningful investigation of the relationship between religion, ‘aṣabiyyah and ‘umrān is possible if investigation is narrowed down to the study of human nature. Hence, according to Ibn Khaldūn, what is true of human nature is also true of ‘umrān. Stated differently, the rules applicable to human nature are applicable to ‘umrān and political institutions.

    Most cases of chronic fissure do not respond to medical treatment. Razi and Ibn Sina were 2 of the best-known scientists of ancient Persia. The purpose of this study was to find out new scientific evidence in modern medicine about their recommendations, in order to find certain clues to conduct useful researches in the future. First, treatments of anal fissure mentioned by Razi and Ibn Sina were reviewed. Then, literature search was made in electronic databases including PubMed, Scopus, and Google Scholar. Management of anal fissure according to Razi's and Ibn Sina's practices is done based on 3 interventions: lifestyle modifications, drug treatments, and manual procedures. Almost all remedies suggested by Razi and Ibn Sina have shown their effects on fissure in ano via several mechanisms of action in many in vitro and in vivo studies; Still there is lack of human studies on the subject. © The Author(s) 2016.

    Directory of Open Access Journals (Sweden)

    Seyyedeh Maryam Rozatian

    2010-03-01

    Full Text Available Abstract  Salaamaan and Absaal is a mysterious story that has been being passed around with several narratives and versions. Jaami has composed a poem based on one of these narratives by the Hanin-e Ibn-e Iss-haq, translated from Greek to Arabic in the third Hijri century ( 9th century A.D.. His interpretations of the story’s mystical secrets had occupied the minds of so many commentators such as “Khajeh Nassir-e Toosi”. Jaami, based on this philosophical interpretation by Khajeh Nassir, offered a rather mystical but short interpretation of the mysteries of this story at the end of his poem. In this article, we intend to provide a different analysis of the mysteries of this story based on the ancient frameworks discussed in Jung’s psychology. Karl Gustav Jung was the founder of the Psychoanalysis and archetypal criticism who combined his psychological perspectives with Hermetic, Gnostic, and the Indian notions. Since the original story is Greek, an Indian influence on the story is conceivable and the ancient frameworks of Jung in analyzing the mysteries will be very revealing .

  17. The Psycholinguistic Theories in the Muqaddimah of Ibn Khaldūn

    Directory of Open Access Journals (Sweden)

    Ahmad Shehu Abdussalam

    1995-12-01

    Full Text Available A review of psycholinguistic theories found in the Muqaddimah shows the breadth of Ibn Khaldūn's understanding of human behaviour, including language behaviour. His views on the influence of change on human habits, the relationship between language, knowledge and perception, and on the influence of constant repetition on language acquisition are, with minor modifications, valid even in the contemporary period. The causes he described for language corruption and the limitation of non-Arabs in learning Arabic are still worth examining.

    The declaration of the recipients adverse reactions (RAR) is one of the field haemovigilance activities. It provides an evaluation of transfusion side effects and thus prevents their appearance. The aim of this study is to analyze, over 14 years, the RAR supports reported in Rabat Ibn Sina hospital. All of the RAR supports sending to the blood transfusion service were analyzed. The data collected from these supports are: clinical characteristics of the patient, type of incident observed and type of labile blood products (LBP) transfused. A total of 353 RAR were declared with a mean cumulative incidence of 1.7/1000 LBP delivered. Febrile non-hemolytic transfusion reactions represent 72.8% of the RAR declared. The RAR were classified as grade 1 in 87.1% of cases and were secondary to a transfusion of the red cell concentrates in 81.9%. ABO incompatibility was found in four cases (0.02/1000 LBP delivered). The number of RAR reported by Rabat Ibn Sina hospital remains underestimated. Management and traceability RAR and rigorous investigation, under the responsibility of the corresponding haemovigilance contribute to the improvement of transfusion safety.

    Full Text Available This article introduced into academic circulation information of such a historical source as “Nukhbat al-dahr fi ‘aja’ib al-barr wa-al-bahr” (Excerpts of Time on the Marvels of the Land and Sea on Kipchak clans and Turkic tribes of Dasht-i Kipchak. The material of the study is drawn from this source. Main scientific result of this work was the source’s translation into Russian accompanied by scientific comments. Sheikh Shams al-Din Abu Abdallah Muhammad Abu Talib al-Ansari al-Sufi al-Dimashqi was the author of this work. Some scholars have mistakenly confuse him with another chronicler named Shihab al-Din Ahmad ibn Yahya Ibn Fadlallah al-Omari al-Dimashqi. There is a widespread misconception that while writing on Kipchak clans and Turkic tribes al-Dimashqi used the data of such an author as Muhammad ibn Ibrahim ibn Yahya al-Ansari al-Qutub al-Warraq al-Vatvat, also known as Ahmad al-Tini. After had studying the manuscripts of al-Tini and al-Dimashqi, we did not notice the connection between these two authors regarding their information about Kipchak clans and Turkic tribes of Dasht-i Kipchak. After had studying the information about Kipchak clans and Turkic tribes of Dasht-i Kipchak, we put forward the theory that 16 ethnonyms previously identified as Kipchak clans, are actually the etnonyms of eight Kipchak clans and eight Turkic tribes. The article also contains the extraction from “Nukhbat al-dahr fi ‘aja’ib al-barr wa-al-bahr” regarding the geography of Dasht-i Kipchak and the countries inhabited by the Turks. The following data are unique in this source: 1. The text describes such rivers as Ceyhun (Amu Darya, Seyhun (Syr Darya, Itil (Volga, as well as Khorezm and Khazar Seas (Aral and Caspian Seas. 2.

    Ibn Sina is regarded as one of the greatest physicians, thinkers and medical scholars in the history of medicine. Ibn Sina, a Persian scholar in the medieval era, wrote a famous book of medicine, the Canon of Medicine. The book was adopted as the main textbook of medicine in most Western and Persian universities. In the present critique, we analyzed the functional and anatomic descriptions of the heart, airways and the lungs as viewed by Ibn Sina in volume three of the Canon of Medicine textbook, and compared them to modern anatomy texts.

    Full Text Available AIM: To study the mechanism of road traffic collisions (RTC, use of safety devices, and outcome of hospitalized pediatric and youth RTC injured patients so as to give recommendations regarding prevention of pediatric RTC injuries. METHODS: All RTC injured children and youth (0-19-year-olds who were admitted to Al Ain City's two major trauma centers or who died after arrival to these centers were prospectively studied from April 2006 to October 2007. Demography of patients, road-user and vehicle types, crash mechanism, usage of safety devices, injured body regions, injury severity, Revised Trauma Score, Glasgow Coma Scale, intensive care unit admissions, hospital stay and mortality were analyzed. RESULTS: 245 patients were studied, 69% were vehicle occupants, 15% pedestrians, 9% motorcyclists and 5% bicyclists. 79% were males and 67% UAE citizens. The most common mechanism of RTC was rollover of vehicle (37% followed by front impact collision (32%. 32 (13% of vehicle occupants were ejected from car. 63% of ejected occupants and 70% of motorcyclists sustained head injuries. Only 2% (3/170 vehicle passengers used seatbelts and 13% (3/23 motorcyclists a helmet. CONCLUSIONS: Male drivers and UAE nationals were at high risk of RTC as drivers and as motorcyclists. Ejection rate was high because safety restraint use was extremely low in our community. More education and law enforcement focusing especially on car/booster seat use is needed.

    Background Although vitamin D deficiency has been studied in various adult populations, there are few data on the prevalence of this nutritional deficiency among healthy adolescents in the United Arab Emirates (UAE). This study was conducted to determine the prevalence of vitamin D deficiency and to examine its correlates in adolescents aged 15 to 18 years. Methods This was a cross-sectional study in urban schools. Healthy adolescents (N=315) from a sample of 8 schools were randomly selected from the 142 schools in Al Ain, Abu Dhabi Emirate. Outcomes measured included serum concentrations of 25-hydroxy vitamin D (25OHD), plasma lipids, blood sugar, blood pressure and anthropometric data, nutrition and lifestyle variables. Results Fourty-one participants (19.7%) were vitamin D deficient (serum 25OHD level ≤15 ng/mL [≤37.5 nmol/L]. Using a cutoff level of 25(OH) D of ≤20 ng/ml [≤50 nmol/l] 143 participants (45.4%) were vitamin D insufficient. Overall 65.1% of study participants were either vitamin D deficient or insufficient. The prevalence of vitamin D deficiency varied between boys (10%) and girls (28%). In a final multivariate model, serum 25(OH) D concentrations were inversely correlated with female gender, consumption of fast food per week, and body mass index and positively correlated with physical activity scores after adjustment for age. Conclusions Vitamin D deficiency and insufficiency were highly prevalent in adolescents, and more common in girls. PMID:23311702

    Full Text Available Islam, through the Quran, proclaims that its mission includes the teachings to the whole universe, Everything in the universe is maintained by Islam, and none of the symptoms are ignored. The revelations also include the traditions of the Prophet that are authentic (shahih and good (hasan in quality. Both the Quran and maqbulah hadiths are accepted by Muslims on the basis of faith. When some experts of UIN Walisongo from various disciplines try to understand the sacred words of these two resources, their understanding continues, reaching the paradigm of the unity of science which essentially unites the normative, social, and natural sciences. The effect of this paradigm has brought up an issue for the author. Is there any hadiths or Prophetic traditions that can be used as a grand theory in the management disciplines of Islamic education.To address this issue, the authors conducted a literature research with the title Development of Islamic Education Management Module. Sources of data were focused on nine books of Hadiths : Sahih al-Bukhari, Sahih al-Muslim, Sunan Abu Dawud, Sunan at-Turmudzi, Sunan an-Nasai, Sunan Ibn Majah, Sunan ad-Darimi, Muwatta Malik, and Musnad Imam Ahmad bin Hanbal in the form of digital data Lidwa Reader Software Book 9 Imam Hadith. The findings of the study stated that the meaning of the word Rabb includes: creating, nurturing, maintaining, teaching, educating, and organizing. Thus, in an academic term, the word Rabb implies a manager or leader. Meanwhile, in the concept of comprehensive manager it contains at least 14 nomenclature denotations: planning, responsibility, organization, coordination, system of employee payroll, learning, resources, humanity, principle of making it easier for the manager to the employee, motivated to achieve optimal performance, preventing unproductivity, education participation, institutional costs, monitoring, and evaluation system. Each nomenclature has numerous hadiths that could serve

  5. The stratigraphic record of Khawr Al Maqta, Abu Dhabi, United Arab Emirates

    Well-constrained modern depositional analogues are vital to the development of accurate geological reservoir models. The development of realistic hydrocarbon reservoir models requires the application of high-precision, well-constrained outcrop and sub-surface data sets with accurately-documented facies geometries and depositional sequence architectures. The Abu Dhabi coastline provides the best modern analogue for the study of ramp-style carbonate depositional facies akin to those observed in the sub-surface reservoirs of the United Arab Emirates (UAE). However, all previous studies have relied on temporally limited surface datasets. This study employed thirty five shallow subsurface cores spanning the width of the Khawr Al Maqta - the narrow shallow tidal channel that separates Abu Dhabi Island from the mainland. The cores were taken over a transect measuring 1.2 km in length by 50 m wide thus providing a high-resolution record of sub-surface facies geometries in a stratigraphically complex setting. Geometries in these Pleistocene to Holocene facies are complex with interdigitating, laterally heterogeneous carbonate, siliciclastic and evaporite units represented throughout the area of the study. Carbonate facies range from molluscan rudstones to marls and are all indicative of deposition in a shallow, relatively low energy marine setting akin to that seen in the environs of Abu Dhabi Island today. Texturally mature quartz sands occur as thin lenses and as thin cross bedded or laminated horizons up to twenty five centimetres thick. Glauconitic mudstones are common and locally exhibit evidence of rootlets and desiccation cracks. Evaporites are present in the form of gypsum occurring as isolated crystals and nodules or as massive chicken-wire units in excess of three metres thick. All of these textures are consistent with evaporite development in the shallow subsurface. Early, shallow-burial diagenesis has been important. Bioclasts are pervasively leached throughout

    Full Text Available Ibn al-Ḥājj al-‘Abdarī a Maliki jurist in Mamluk Cairo, denounced a religious “innovation” (bid‘a that had apparently become current in fourteenthcentury Egypt: “Infidels” would interrupt the Muslim Friday sermon in order to profess or reiterate their conversion to Islam before the entire congregation. Ibn al-Ḥājj urged preachers not to tolerate such interruptions under any circumstances, a posture that seems at odd with Mamluk policy of inducing such conversions especially among the Coptic community. The Maliki jurist’s legal arguments furnish new insights into the hitherto unexplored role of the Friday liturgical sermon in the conversion to Islam. This article will explain the legal basis of Ibn al-Ḥājj’s opposition to this practice, propose some explanations for the motivations behind the would-be convert’s interruption of the sermon, and relate this phenomenon to the historical context of tense Muslim-Christian relations in fourteenth-century Mamluk Egypt.

    Ibn al-Ḥaŷŷ al-‘Abdarī, un jurista malikí en el Cairo mameluco, denunció una “innovación religiosa” (bid‘a que se extendió en el Egipto del siglo XIV. Los “infieles” interrumpían el sermón del viernes, aparentemente, para proclamar o reiterar su conversión al Islam ante la congregación. Ibn al-Ḥaŷŷ instó a los predicadores a no tolerar dichas interrupciones bajo ninguna circunstancia –postura que parece contradecir a la política impuesta por los mamelucos de forzar la conversión de los infieles, sobre todo de los procedentes de la comunidad copta. Los argumentos legales de Ibn al-Ḥaŷŷ arrojan nueva luz sobre el papel, hasta entonces ignorado por los estudiosos, del sermón del viernes en la conversión al islam. El artículo analiza las bases jurídicas de la oposición manifestada por Ibn al-Ḥaŷŷ hacia esta práctica, explica los posibles motivos que indujeron a los conversos a interrumpir el serm

He offers the concept of love of God(mah}abbah, oneness of God (tawh}id, fear of God (makha>fah , and gnosis (ma’rifah to the mankind. According to al-Ghaza>li , someone who loves God must love God's creatures as well. This concept leads to the good behaviors such as desire to unite oneself with God by repentance (tawbah, asceticism (zuhd for fear of being far from God, trusting in God (tawakkul, and being pleased with all decisions and provisions of God (rid}a. These spiritual stages will lead to the degree of knowing God (ma'rifah. Modern society, that often feel alienated, will find the book Ih}ya> 'Ulu> m al-Di>n as a cooling oasis.

  9. Fabrication of the tricontinuous mesoporous IBN-9 structure with surfactant CTAB

    2011-12-13

    IBN-9 is the first tricontinuous mesoporous material, consisting of three identical interpenetrating channels that are separated by a single continuous silica wall. It was originally synthesized using a specially designed surfactant as template. The need of special surfactant in the synthesis inhibits extensive investigation of this novel structure and its applications. We demonstrate in this study that such a complicated tricontinuous mesostructure can also be fabricated from the most common and commercially available surfactant cetyltrimethylammonium bromide (CTAB) with the help of polar organic additives, e.g., n-butanol. The role of n-butanol is to finely tune the surface curvature of the organic/inorganic interface during the cooperative self-assembly process. Electron microscopic techniques are employed to identify different mesostructures from the mixture. This study reveals the possibility of discovering unprecedented mesostructures from conventional surfactant-water- silicates systems. © 2011 American Chemical Society.

    Background Over the last 30 years the citizens of the United Arab Emirates have experienced major changes in life-style secondary to increased affluence. Currently, 1 in 5 adults have diabetes mellitus, but the associations (clustering) among risk factors, as well as the relevance of the concept of the metabolic syndrome, in this population is unknown. Aim To investigate the prevalence and associations among cardiovascular risk factors in this population, and explore to what extent associations can be explained by the metabolic syndrome according to ATP-III criteria. Method A community based survey, of conventional risk factors for cardiovascular disease was conducted among 817 national residents of Al Ain city, UAE. These factors were fasting blood sugar, blood pressure, lipid profile, BMI, waist circumference, smoking, or CHD family history. Odds ratios between risks factors, both unadjusted and adjusted for age and sex as well as adjusted for age, sex, and metabolic syndrome were calculated. Results Various risk factors were positively associated in this population; associations that are mostly unexplained by confounding by age and sex. For example, hypertension and diabetes were still strongly related (OR 2.5; 95% CI 1.7–3.7) after adjustment. An increased waist circumference showed similar relationship with hypertension (OR 2.3; 95% CI 1.5–3.5). Diabetes was related to an increased BMI (OR 1.5; 96% CI 1.0–2.3). Smoking was also associated with diabetes (OR 1.9, 95% CI 1.0–3.3). Further adjustment for metabolic syndrome reduced some associations but several remained. Conclusion In this population risk-factors cluster, but associations do not appear to be explained by the presence/absence of the ATP-III metabolic syndrome. Associations provide valuable information in planning interventions for screening and management. PMID:19371412

    The Anniston Community Health Survey, a cross-sectional study, was undertaken in 2005–2007 to study environmental exposure to polychlorinated biphenyl (PCB) and organochlorine (OC) pesticides and health outcomes among residents of Anniston, AL, United States. The examination of potential risks between these pollutants and metabolic syndrome, a cluster of cardiovascular risk factors (i.e., hypertension, central obesity, dyslipidemia and dysglycemia) was the focus of this analysis. Participants were 548 adults who completed the survey and a clinic visit, were free of diabetes, and had a serum sample for clinical laboratory parameters as well as PCB and OC pesticide concentrations. Associations between summed concentrations of 35 PCB congeners and 9 individual pesticides and metabolic syndrome were examined using generalized linear modeling and logistic regression; odds ratios (OR) and 95% confidence intervals (CI) are reported. Pollutants were evaluated as quintiles and as log transformations of continuous serum concentrations. Participants were mostly female (68%) with a mean age (SD) of 53.6 (16.2) years. The racial distribution was 56% white and 44% African American; 49% met the criteria for metabolic syndrome. In unadjusted logistic regression, statistically significant and positive associations across the majority of quintiles were noted for seven individually modeled pesticides (p,p′-DDT, p,p′-DDE, HCB, β-HCCH, oxychlor, tNONA, Mirex). Following adjustment for covariables (i.e., age, sex, race, education, marital status, current smoking, alcohol consumption, positive family history of diabetes or cardiovascular disease, liver disease, BMI), significant elevations in risk were noted for p,p′-DDT across multiple quintiles (range of ORs 1.61 to 2.36), for tNONA (range of ORs 1.62–2.80) and for p,p′-DDE [OR (95% CI)] of 2.73 (1.09–6.88) in the highest quintile relative to the first.

  15. Development and status of the AL Mixed Waste Treatment Plan or I love that mobile unit of mine

    Bounini, L.; Williams, M.; Zygmunt, S.

    1995-01-01

    Nine Department of Energy (DOE) sites reporting to the Albuquerque Office (AL) have mixed waste that is chemically hazardous and radioactive. The hazardous waste regulations require the chemical portion of mixed waste to be to be treated to certain standards. The total volume of low-level mixed waste at the nine sites is equivalent to 7,000 drums, with individual site volumes ranging from 1 gallon of waste at the Pinellas Plant to 4,500 drums at Los Alamos National Laboratory. Nearly all the sites have a diversity of wastes requiring a diversity of treatment processes. Treatment capacity does not exist for much of this waste, and it would be expensive for each site to build the diversity of treatment processes needed to treat its own wastes. DOE-AL assembled a team that developed the AL Mixed Waste Treatment Plan that uses the resources of the nine sites to treat the waste at the sites. Work on the plan started in October 1993, and the plan was finalized in March 1994. The plan uses commercial treatment, treatability studies, and mobile treatment units. The plan specifies treatment technologies that will be built as mobile treatment units to be moved from site to site. Mobile units include bench-top units for very small volumes and treatability studies, drum-size units that treat one drum per day, and skid-size units that handle multiple drum volumes. After the tools needed to treat the wastes were determined, the sites were assigned to provide part of the treatment capacity using their own resources and expertise. The sites are making progress on treatability studies, commercial treatment, and mobile treatment design and fabrication. To date, this is the only plan for treating waste that brings the resources of several DOE sites together to treat mixed waste. It is the only program actively planning to use mobile treatment coordinated between DOE sites

    We present new evidence supporting the quasi-unit-cell description of the Al 72 Ni 20 Co 8 decagonal quasicrystal which shows that the solid is composed of repeating, overlapping decagonal cluster columns with broken tenfold symmetry. We propose an atomic model which gives a significantly improved fit to electron microscopy experiments compared to a previous proposal by us and to alternative proposals with tenfold symmetric clusters.

    2012-01-01

    Full Text Available The Ti-6Al-4V octahedral porous material unit is designed to calculate its load. In this paper, ANSYS is adopted for the load simulation of the unit. And a simplified model of dimensional theoretical calculation is established, by which the analytical equation of the fracture load is obtained and the calculation of the load of Ti-6Al-4V is completed. Moreover, selective laser melting is adopted in processing the Ti-6Al-4V porous material unit. The experimental value of fracture load of this material is obtained through compression experiment. The results show that the simulation curves approximate the variation tendency of the elastic deformation of the compression curves; the curves of theoretical calculation approximate the general variation tendency; and the experimental value of fracture load is very close to the theoretical value. Therefore, the theoretical prediction accuracy of fracture load is high, which lays the foundation for the mechanical properties of the octahedral porous material.

    Studies on the architectural heritage can now be supported by three-dimensional reconstruction of actual buildings. The 3D digital model can be an effective medium for documenting the current state of historic buildings but also to create a resource for researchers who conduct their analysis on historical evolution. Architectural photogrammetry has its own specifications in relation to other photogrammetric applications, however it meets these expectations. The traditional approach requires the use of metric cameras but with the development of computational techniques, this requirement is overcome and opens the way for the use of non-metric camera. The use of the shots that is no longer restricted to the parallel configuration of bundles, the images may be convergent, horizontal or oblique. Combining and modelling several cameras increasingly powerful in resolution and stability, has great scope and the same workflow can be used in varied applications. ISPRS and ICOMOS created CIPA because they both believe that a monument can be restored and protected only when it has been fully measured and documented and when its development has been documented several times, i.e. monitored, also with respect to its environment, and stored in proper heritage information and management systems. In this paper the 3D modelling of an important cultural site using terrestrial photogrammetric techniques for architectural preservation is presented. The site is the mosque of Abdullah Ibn Salam, Built in 1880 at the initiative of Simon Kanoui, also known as the Great Synagogue of Oran was inaugurated in 1918 only. It was one of the largest and most beautiful synagogues in North Africa. It was built with stone imported from Jerusalem. This place of worship became in 1975 the mosque of Abdullah Ibn Salam who was a rich Jew of Medina who was converted to Islam. The structure is modelled using 321 oriented photos taken in five series of shots that cover all the façade and the interior of

    Full Text Available The objective of this research is to describe the concept of Ibnu Jarir al-Tabari about al-Qur’an, tafsir and ta’wil. Ibn Jarir al-Tabari is an outstanding expert in the classic Islamic tradition. His knowledge in hadits, fiqh, lughah, history, and tafseer is unquestionable. This study uses an analytical descriptive design. The findings show that: Firstly, in defining al-Qur’an, al-Tabari focused on the al-Qur’an as an Arabic language text, not in other language. Secondly, al-Qur’an is written in sab’ah ahruf. It means that there are 7 different kinds of language with the same meaning. Thirdly, al-Qur’an comes from seven heaven’s door. Fourthly, there is no different word between tafseer and ta’wil. They have same meaning. These concepts are different to other concepts proposed by other ulama.

    2011-12-01

    Full Text Available One of the fundamental problems of Theoretical Mysticism is the explanation of the world as being something other than God after having accepted the Unity of Existence. This paper seeks to present, after having explained certain necessary premises, the theory of manifestation as one that can explain and analyze multiplicity.In this article we especially seek to solidify the relation of such claims to mystics in general and to the adherents of the Ibn ‘Arabian school of thought in particular. This is especially important because in some of the works of many specialists in this field we find that some unrealistic claims have been definitively attributed in to the Great Sheikh. The only way to counteract such false claims, in any field, including Theoretical Mysticism, is to make it binding upon ourselves to delve into the views of others in a cautious way. We must take the apparent meanings of the sayings of the mystics as a proof in this matter. Therefore the method of research of the writer of this article is to relate the sayings of the Great Sheikh and his commentators while commentating upon and analyzing them as well.

    Full Text Available This article compares various elements of Ibn Khaldūn’s and Douglass C. North’s thoughts on the role of institutions in influencing or forcing economic change. There are a number of interesting similarities in ideas, thoughts, approaches, and methodologies, which prove that New Institutional Economics may actually mirror much of (and can benefit from Ibn Khaldūn’s fourteenth century ideas than was previously thought. Both Ibn Khaldūn’s continuum of badāwah to ḥaḍārah and North’s theory on changes from informal to formal institutions lead to the same fundamental conclusions: (i change is incremental as it is a result in small cumulative changes in the cost-benefit outcomes of the market agents over time, and therefore (ii economic performance inevitably depends on the existence and effectiveness of formal institutions that alter those outcomes. It is also noted that ‘aṣabiyyah or group feeling, another cornerstone of Ibn Khaldūn’s thought, corresponds perfectly to North’s treatise that social cohesion and institutional efficiency are more important than the amount of resource endowment in bringing about economic development and change. In addition, Ibn Khaldūn’s views on the government’s commercial activities are reviewed in the study in light of North’s transaction costs and property rights framework.

    The present report, based largely on fieldwork during 1959-61, describes the results of reconnaissance hydrogeologic studies and exploratory drilling to evaluate the general water-bearing properties of the rocks and the availability of groundwater supplies for irrigation, stock, and village uses in Al Marj area. These studies and the drilling were conducted under the auspices of the U.S. Operations Mission of the International Cooperation Administration. Al Marj area, located in the Province of Cyrenaica on the southern coast of the Mediterranean Sea, contains a land area of about 6,770 square kilometers. Along the Mediterranean shore is a narrow coastal plain that rises evenly to the base of an escarpment that forms the seaward front of an undulating plateau known as. Al Jabal al Akhgiar. The climate is semiarid; seasonal rainfall occurs during the winter months. Owing to orographic effects, the rainfall is somewhat higher in the Jabal than in the coastal plain. The average annual rainfall ranges from about 250 millimeters in the coastal plain to 450 millimeters on the Jabal. All the streams (wadis) of the area are ephemeral and flow only in response to heavy rains of the winter season. From a drainage divide on the Jabal some streams flow north and northwest toward the sea and the others, south and southeast to the interior desert. Solution features, such as limestone sink holes, are common in the coastal plain and a large solution depression occurs near Al Marj. The rocks of A1 Marj area consist predominantly of limestone and some sandstone and shale; they range from Cretaceous to Miocene age. On the coastal plain Miocene limestone is locally mantled by Quaternary alluvial, beach and lagoonal deposits. The Miocene and older beds have a regional southerly dip. These rocks are broken by northeast-trending normal faults in the coastal and inland escarpments. The ground-water reservoir is contained chiefly in fractures, bedding planes, and solution openings in the

    Sleep apnea syndrome is a highly prevalent disorder that is still underdiagnosed and undertreated and whose obstructive form is the most common. The diagnosis is suspected on clinical signs collected by interrogation and questionnaires (Berlin questionnaire and Epworth sleepiness scale), then confirmed by objective sleep study findings (polygraphy or polysomnography). It is necessary to conduct studies in each context on the characteristics and management of sleep apnea syndrome comprising the testing of reliability of the questionnaires. Prospective and descriptive study of 104 patients addressed to sleep consultation at pulmononology Department of Ibn Sina Hospital, Morocco over a period of 5 years (January 2006 to December 2010), agreed to participate in the study, responded to a predetermined questionnaire, and benefited from clinical examination and paraclinical tests including a polygraphy or a polysomnography 59(56.7%) patients had an obstructive sleep apnea-hypopnea syndrome with a similar prevalence in both sexes. 32.2% of patients were obese and 28,8% had cardio-vascular diseases. Snoring, excessive daytime sleepiness and witnessed apnea were found in respectively 79.7%, 50.8% and 16.9%. Berlin questionnaire and Epworth sleepiness scale had an acceptable internal consistency against apnea hypopnea index with a Cronbach's alpha coefficient respectively 0.79 and 0.78. Depending on severity, clinical impact and results of investigations, the adequate treatment has been proposed based on the 2010 recommendations for clinical practice. This study has provided an idea about the profile and the management of patients having an obstructive sleep apnea-hypopnea syndrome and showed that both Berlin questionnaire and Epworth sleepiness scale are two simple and reliable methods in our context. A larger and further study across the country should be considered.

    The cost effective provision of quality care for chronic diseases is a major challenge for health care systems. We describe a project to improve the care of patients with the highly prevalent disorders of diabetes and hypertension, conducted in one of the major cities of the United Arab Emirates. The project, using the principles of quality assurance cycles, was conducted in 4 stages.The assessment stage consisted of a community survey and an audit of the health care system, with particular emphasis on chronic disease care. The information gleaned from this stage provided feedback to the staff of participating health centers. In the second stage, deficiencies in health care were identified and interventions were developed for improvements, including topics for continuing professional development.In the third stage, these strategies were piloted in a single health centre for one year and the outcomes evaluated. In the still ongoing fourth stage, the project was rolled out to all the health centers in the area, with continuing evaluation. The intervention consisted of changes to establish a structured care model based on the predicted needs of this group of patients utilizing dedicated chronic disease clinics inside the existing primary health care system. These clinics incorporated decision-making tools, including evidence-based guidelines, patient education and ongoing professional education. The intervention was successfully implemented in all the health centers. The health care quality indicators that showed the greatest improvement were the documentation of patient history (e.g. smoking status and physical activity); improvement in recording physical signs (e.g. body mass index (BMI)); and an improvement in the requesting of appropriate investigations, such as HbA1c and microalbuminurea. There was also improvement in those parameters reflecting outcomes of care, which included HbA1c, blood pressure and lipid profiles. Indicators related to lifestyle changes

    Summary Il s'agit d'une étude épidémiologique des séquelles de brûlures à propos de 100 cas colligés au service de chirurgie réparatrice et de brûlés du centre hospitalier universitaire Ibn Rochd (Casablanca). Les adultes représentent 55% de la population étudiée, l'âge moyen global est de 20 ans. Le sexe féminin est le plus touché avec 61% des cas. Les brûlures survenues à domicile sont les plus fréquentes avec 80%. L'agent causal le plus incriminé est la petite bouteille de butane avec 44,4%. Plus de la moitié de la population brûlée (55%) sont accueillis initialement au niveau d'hôpitaux régionaux. Le délai de cicatrisation moyen de 7 mois et 11 jours et par conséquent les séquelles mineures (dyschromie dans 90% des cas et prurit dans 49% des cas) et majeures (rétractions dans 86% et l'hypertrophie dans 51%) sont fréquentes. La répartition globale des séquelles montre une prédominance du segment cervicocéphalique avec 89% des cas et des membres supérieurs dans 82% des cas. Les différents aspects anatomocliniques essentiels ont été décrits au niveau de chaque segment corporel. Nos résultats ont été comparés aux données de la littérature, ce qui nous amène à considérer qu'une large campagne de prévention couplée à une meilleure prise en charge initiale, précoce, bien conduite et multidisciplinaire permet non seulement de réduire le nombre de séquelles mais aussi de diminuer leur sévérité.

    The concentrations of equivalent eU, eTh, and K% were determined together with soil gas radon values and carborne gamma-ray survey in order to define the natural radioactivity levels throughout main geological units of Sabkhat al Jabboul region. Forty five soil and rock samples were collected from various lithofacies in each geological unit, and analyzed by γ-ray spectrometric technique for determining the concentration values of major radioelements. Such radiometric data could be used to differentiate between various lithologies of the investigated rocks. Although no distinct radioactive anomalies were found in the area, the radiometric profiles showed some minor variations with slightly higher values than the normal level. Despite the low radioactivity and the lack of rocks diversity in the surveyed area, it was possible to classify some certain rock types based on their radiometric response. The relationships between eU, eTh and their ratios were discussed for the Quaternary, Neogene and Paleogene formations, in order to evaluate the degree of uranium distribution and remobilization. The overall results of this radiometric survey were generally low, and lying within the range of the normal background levels in Syrian. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Amyotrophic lateral sclerosis (ALS) is a fatal motor neuron disease that typically results in death within 2-5 years of initial symptom onset. Multidisciplinary ALS clinics (MDCs) have been established to provide specialty care to people living with the disease. To estimate the proximity of ALS prevalence cases to the nearest MDC in the US to help evaluate one aspect of access to care. Using 2013 prevalence data from the National ALS Registry, cases were geocoded by city using geographic information system (GIS) software, along with the locations of all MDCs in operation during 2013. Case-to-MDC proximity was calculated and analyzed by sex, race, and age group. During 2013, there were 72 MDCs in operation in 30 different states. A total of 15,633 ALS cases were geocoded and were distributed throughout all 50 states. Of these, 62.6% were male, 77.9% were white, and 76.2% were 50-79 years old. For overall case-to-MDC proximity, nearly half (44.9%) of all geocoded cases in the US lived >50 miles from an MDC, including approximately a quarter who lived >100 miles from an MDC. There was a statistically significant difference between distance to MDC by race and age group. The high percentage of those living more than 50 miles from the nearest specialized clinic underscores one of the many challenges of ALS. Having better access to care, whether at MDCs or through other modalities, is likely key to increasing survivability and obtaining appropriate end-of-life treatment and support for people with ALS.

    Full Text Available Within the discipline, the historical roots of ethnology and anthropology are most often traced through European antiquity, the enlightenment and the modern intellectual traditions of the West. Even though this view is somewhat justified (in that it follows a clear continuity in the development and scientification of the discipline in western universities, it, perhaps unintentionally, leaves out the intellectual efforts of Islamic thinkers and travelers, who had also, in their time, encountered various forms of "cultural otherness" and strived to represent and interpret them to their own readers. This paper focuses on Ibn Battuta’s decades of travel through Muslim lands – and beyond – and is envisioned as a theoretical experiment the purpose of which isilluminating the significance of Ibn Battuta’s writings, not only for the historical but also for the contemporary aspects of our discipline.It is a reflection on the ethnographic aspect of Ibn Battuta’s writings about the people and cultures which he encountered in his travels.

One of that forbidden contracts is two sales in one contract (bay’atayn fi bay’ahor s}afqatayn fi s}afqah. There are narrations of the Ahadith which forbids this type of contract. The paper discusses the authenticity of these narrations and its legal meaning. According to the science of Hadits that daif (weak Hadith could not be considered as valid source of law. There are three narrations related to this topic i.e. through Abu Hurayrah, Amru ibn Shuaib and Ibn Mas’ud. The Prophet (pbh has forbidden two sales in one contract. This Hadits is generally considered as Sahih hence some transactions which come under this type are deemed as void. Muslim scholars have different opinion with regard to the meaning of this Hadits. There are some forms of contract which are forbidden is Islamic Law such as 1.  Bay’ al-ienah, 2.Bay’ al-Kali’ bil Kali’ and Bay’ al-Taqsit or Ta’jil (on deferred payment. This paper is an effort to shed the light on these types of contract referring to the opinions of Muslim intellectuals from different school of thought (Hanafite, Shafiite, Malikite and Hanbalite with some conclusion et the end.

  18. An Islamic Approach to Studying History: Reflections on Ibn Khaldūn’s Deterministic Historical Approach

    Directory of Open Access Journals (Sweden)

    Ali White

    2009-12-01

    Full Text Available Abstract: This paper argues that patterns exist in history, and that these can —and should — be discerned. By doing this, Muslim intellectuals will only be resuming an intellectual and spiritual journey begun over 600 years ago, by Ibn Khaldūn, who invented sociology and the scientific study of history, basing himself on the methodology of the Qur´ān. This paper examines Khaldūn’s deterministic historical approach, comparing it to the secular attempt to understand history in Karl Marx’s “historical materialism.” Khaldūn’s classification of societies (as being either based on human fiṭrah or tending towards an animal-like existence is examined and applied to current conditions. It is argued that Muslims need to learn how to use Khaldūn’s deterministic approach, critically applying it to today’s changed conditions, to contribute to the conscious creation of a new, Allah-centred global civilisation.

  19. The "Prince of Medicine": Yūhannā ibn Māsawayh and the foundations of the western pharmaceutical tradition.

    Science.gov (United States)

    De Vos, Paula

    2013-12-01

    This essay examines three medieval pharmaceutical treatises purportedly authored by Yūhannā ibn Māsawayh (anglicized to John Mesue) and traces their immense influence on the development of pharmacy in early modem Europe and the Hispanic world. Despite the importance of these works throughout the early modern period, Mesue is relatively unknown in the history of pharmacy and medicine, and his exact identity remains unclear. This essay argues that "Mesue" was most likely a pseudonym used by an unknown author of the Latin West and that the three works were crafted to meet the demands of the developing "medical marketplace" of late thirteenth-century Europe, where the manuscripts first appeared. At the same time, however, as the Arabic reference of the pseudonym suggests, these treatises were clearly products of the medieval Islamic world, including many innovations that would provide the basis for the theory and practice of pharmacy for centuries and arguably formed part of the artisanal epistemological influence on the Scientific Revolution.

    According to the definition stated in the beginning of the "Al-Qanun fi al-Tibb" (the Qanun of Medicine); medicine is a science, from which one learns the states of the human body; health and disease and what causes them, in order to preserve good health when it exists, and restore it when it is lacking. Based on this issue, Avicenna believes that medical science belongs to all human without any limitation, and maintenance of health is one of its prime objectives. He states that many disorders are related to errors in the 6 factors, which are essential for maintaining health and preventing diseases. Avicenna described these six essential factors (lifestyle factors) in his masterpiece, Qanun of Medicine, as "Asbab-e-Settah-e-Zaruriah." Based on the teaching of Avicenna, the first step for maintaining health and approaches to treatment is modification of lifestyle factors, including of nutrition, physical activity, etc.

    Full Text Available The concept of the creation of universe offered by Neo-Platonism philosopher such as al-Kindi, al-Farabi, and Ibnu Sina are philosophical concept existed and came as an early moment of development of Islamic philosophy interrelated to God, ultimately about his Existence and Characteristics. One of the topics is how God created the universe. According to al-Farabi and Ibnu Sina, God created this universe by way of emanation in order to prevent Himself from the new attitudes. Consequently, universe has eternal feature (qadim as God as well, in the case of everything overflowed from qadim is also qadim. Al-Ghazali refuted this theory because it contradicted with al Qur’an’s thought which clearly explained that God created the entire universe. The universe should not qadim and it means that God existed in the first, and then created universe later as we know today. On the contrary, in the view of Muslim philosopher, the universe should be qadim because God created it from all eternity. For them, it is impossible that God existed by Himself without any creation before. God, according to them is impossible to be changed, so that is impossible as well if God changed from did not create yet before and then creates. Al-Ghazali persistently opposed the concept of eternity. Al Ghazali saw if this universe is qadim so it is impossible that universe created by God. The concept of qadim will led to the conclusion that universe born by itself, it was not created by God. This critique has been written by al-Ghazali in Tahafut al-Falasifah. This paper will present the concept of eternity which was discussed by al-Farabi and Ibn Sina and al Ghazali’s critique toward it as well.

It will uncover the multidimensional perspective of the concept of faith based on sin (dhanb and repentance (tawbah through the mystical philosophy of a Syrian scholar, Abd al-Ghani al-Nabulusi (d. 1143/1741 of the 18th century Ottoman Damascus who contributed to the field of Sufism particularly based on Ibn ‘Arabi’s thought of wahdat al-wujud (oneness of being and insan kamil (the perfect man. Nabulusi believes that anyone who lived during the inexistence of prophet’s revelation, inhabited an isolated place cut off from information about Islam, or lived in dar al-harb and did not make a hijra to dar al-islam could not be regarded as sinful in their deeds. However, faith in Allah is essential and infidelity is not forgiven regardless whether or not they live in dar al-islam or dar al-harb. Further, Nabulusi insists that true faith can be achieved by understanding the sin of existence; the ignorance of the difference of existence between Allah and men.  [Artikel ini menjelaskan identitas keberagamaan umat Islam minoritas yang dituntut untuk menerapkan syariat, namun harus hidup di negara non-muslim, dengan mendiskusikan perspektif multidimensional terhadap konsep dosa dan tobat seperti dikembangkan oleh Abd al-Ghanī al-Nabulusī (1143/1741, seorang sufi pemikir Syria, khususnya  wahdat al-wujūd dan insan kamil, yang hidup di masa kesultanan Usmani di Damaskus.

    Renal oncocytoma is a rare and benign renal tumor. Only few cases have been reported in Moroccan populations. In the present study, we report our experiences in the diagnosis, management and follow-up of this disease. We report on six cases of renal oncocytoma indentified between 1990 and 2008 in the urology department of "CHU Ibn Sina" in Rabat. These six cases are listed among 130 kidney tumors reported during the study period. We assess the clinical, radiological and therapeutic features of the patients and we review literature. Six cases of renal oncocytoma, representing 4.6% of all primitive kidney tumors treated in our institution during the study period. The mean age was 53 ±9.7 years (range 34 to 61 years). One patient was asymptomatic at presentation, five patients (83%) had flank pain and two (33%) had macroscopic hematuria. The tumor was right sided in 4 cases (66%) and left sided in 2 cases (33%). All patients underwent CT scan which showed, in three cases, a centrally located stellate area of low attenuation. The clinical suspicion of oncocytoma was made preoperatively in only 3 patients by imaging studies, but the suspicion of renal cell carcinoma persist and all patients were treated with radical nephrectomy. Definitive diagnosis was made in all cases postoperatively. All the tumors were well circumscribed but unencapsulated. The mean tumor size was 8,75±2,04 cm. Four patients were classified at stage pT2 and two at stage p T1. Most of the pathological features in our patients were typical of this entity. Predominant cell type was a typical oncocytoma with general low mitotic activity. No extension to peri-nephric fat tissue or lymphovascular invasion was observed. After a mean follow-up of 36 months (range 26-62 months), there was neither recurrence nor death from oncocytoma. Accordingly, the disease-specific survival was 100%. Renal oncocytoma has a benign clinical course with excellent long-term outcomes. In our series, it happened mostly in

  15. Diet and dietetics in al-Andalus.

    2006-08-01

    Al-Andalus society (711-1492) based its idea of health on the wisdom of Classical Greece, the Hippocratic-Galenic theories, as well as the Persian and Hindu cultures. The twelfth century in al-Andalus is considered to be the most prolific period for works of a scientific and technical nature. At the time, the main treatises on dietetics were written and this science reached its widest expression with such leading figures as Ibn Wāfīd, Avenzoar, Averroes and Maimonides, whose works revealed the first scientific knowledge on the nutritional processes of the human body. Diet was regarded as being essential for health and the prevention of disease. Dietary guidelines were written for different age groups, different body types and different seasons of the year. The amount of food to be ingested, the number of meals recommended and the order in which the food should be consumed were all issues that were discussed. A variety of foods were thought to have medicinal properties, some of which are known today. The diet in al-Andalus was varied and very probably made a substantial contribution to the origin of the present-day Mediterranean diet, rich in olive oil, wholemeal cereals, fruit and vegetables, fish, lamb, poultry, nuts and spices. We also find that many of the terms in current use in diet and agriculture are a living testimony to the Arabic influence, as are many of the dishes of our varied Mediterranean gastronomy.

    Christopher P McKay

    Full Text Available Salt flats (sabkha are a recognized habitat for microbial life in desert environments and as analogs of habitats for possible life on Mars. Here we report on the physical setting and microbiology of interdune sabkhas among the large dunes in the Rub' al Khali (the Empty Quarter in Liwa Oasis, United Arab Emirates. The salt flats, composed of gypsum and halite, are moistened by relatively fresh ground water. The result is a salinity gradient that is inverted compared to most salt flat communities with the hypersaline layer at the top and freshwater layers below. We describe and characterize a rich photosynthetically-based microbial ecosystem that is protected from the arid outside environment by a translucent salt crust. Gases collected from sediments under shallow ponds in the sabkha contain methane in concentrations as high as 3400 ppm. The salt crust could preserve biomarkers and other evidence for life in the salt after it dries out. Chloride-filled depressions have been identified on Mars and although surface flow of water is unlikely on Mars today, ground water is possible. Such a near surface system with modern groundwater flowing under ancient salt deposits could be present on Mars and could be accessed by surface rovers.

    Usando como hilo conductor la recuperación y superación del legado matemático -y científico- griego, se analizarán en esta colaboración cuatro importantes efemérides matemáticas: la muerte de Thābit ibn Qurra (901, los nacimientos de Gerolamo Cardano (1501 y Pierre de Fermat (1601 y la publicación de las Disquisitiones Arithmeticae de Karl F. Gauss (1801. Con esta perspectiva, consideraremos las contribuciones de Thābit al primer renacimiento de la ciencia y filosofía griegas que se produjo a partir del siglo VIH de manos de los árabes. Gerolamo Cardano aparecerá como actor de otro Renacimiento -este lo solemos escribir con mayúscula-: el italiano; que en este caso culminó con la recuperación para la Europa Occidental de la matemática, filosofía y ciencia griegas, además del arte. La figura de Pierre de Fermat se mostrará decisiva en la creación durante el siglo XVII de las dos herramientas matemáticas que suponen, tras dos mil años de historia, la superación conceptual y operativa de la matemática griega: la geometría analítica y el cálculo diferencial. Aunque en otra medida que Thābit, Cardano y Fermat, las Disquisitiones también pueden conectarse con el espíritu del mundo griego; fue, de hecho, el mismo Gauss quien lo invocó para darle realce y significado a uno de los principales resultados de su libro -el estudio de los polígonos regulares que admiten ser construidos con regla y compás-: «Es ciertamente atónito que nada nuevo se haya añadido a esta teoría desde los tiempos de Euclides hace ya 2.000 años».

    Al-Biruni's was of Persian descent. He was born in Horesmiya and had studied mathematics, history and medicine. Acquiring knowledge from these sciences, he wrote an outstanding work on chronology of several nations and devoted it to Ziyarit ruler Kabus. He made a chronological overview of calendars from many nations, including Persians, Greeks, Egyptians, Jews, Melkitian and Nestorian Christians, Sabeyaans as well as the old Arabs. Data presented in the work, according to the later authors, were taken from very reliable sources. He was contemporary of Ibn-Sina, and thanks to their friendship, they have discussed very much miscellaneous topics. He belonged to the group of scholars, taken by Gaznevian Soultan Mahmud to a long journey to India. Afterwards Al-Biruni wrote and published detailed work "Description of India"--a work on cultural history of India. Due to excellent abilities of Al-Biruni as a philosopher and scholar, there are still significant and reliable notes about buddhistic philosophy, structure of castes and Brahmans' life style. In this Al-Biruni's masterpiece, there are many comparative analysis of Suffism and certain Indian philosophical methods. Al-Biruni's most important work is "Pharmacopoeia"--"Kitab al-saydala", which brilliantly describes all medicaments. This work has been published in many languages. He also wrote few works on astronomy and astrology. In those works he has explained some astrological events through scientific approach in a such peculiar way that nobody has ever explained before. He was also interested in sciences like geology, mineralology, geography, mathematics, psychology and many others.

    Acinetobacter baumannii , is an emerging nosocomial multidrug resistance pathogen with the rapid spread of clones being reported in health-care settings and hospitals worldwide. Carbapenem resistance in this bacterium has been attributed to D OXA β-lactamases with OXA-51-like β-lactamase, being present in all A. baumannii isolate. The present study looks into the antibiotics susceptibility and molecular characterization of clinical A. baumannii isolates from Intensive Care Unit (ICU) samples in Al-Hofuf, South-eastern region of Saudi Arabia. Eleven strains of ICU A. baumanni i isolates were used for the investigation. Bacteria isolation was by basic microbiological techniques. Organisms identification and antibiogram susceptibility testing was by the BioMerieux VITEK 2 compact automated system (BioMerieux, Marcy I'Etoile France), according to the manufacturers guidelines. Confirmation of A. baumannii was by the presence of the OX-51 gene, also, carbapenemase encoding resistant genesbla OXA-23 , bla OXA-40 , and bla OXA-51 , were analyzed using multiplex PCR. The Student's t test was used to analyze the obtained data for between group comparisons with statistically significance level set at P < 0.05. Eight of the isolates were confirmed to be A. baumannii . Five of which were resistant to the carbapenems against which they had been tested. One isolate was resistant to tigecycline, whereas three tested intermediate to the drug. OXA-23 was detected in isolates 1, 4, 5, 6, and 7. It can, therefore, be concluded that the probable predominate carbapenems resistant genes in ICU isolates from the present investigation, are those associated with OXA-23.

    La main est fréquemment exposée aux brûlures, entraînant des séquelles esthétiques et fonctionnelles. Le traitement de ces séquelles est surtout chirurgical et consiste en la greffe de peau, dont le type dépend de la localisation de la brûlure et du type des séquelles. Dans ce travail rétrospectif, nous rapportons une série de 152 cas de brûlures des mains colligés au service de chirurgie plastique du Centre Hospitalier Universitaire Ibn-Sina de Rabat sur une période de dix ans, allant de 1998 à 2007. Les indications thérapeutiques dépendent du type de séquelles et de la localisation de la brûlure. En tout, 97 patients ont bénéficié d'une greffe cutanée, dont 76% par greffe de peau totale, 21% par greffe de peau demi-épaisse et 3% par peau fine. Les séquelles des brûlures des mains posent un problème thérapeutique majeur, malgré la diversité des procédés chirurgicaux, d'où l'intérêt de la prévention.

    Full Text Available Objective: to identify the main reasons for the dynastic marriage between Mamluk Sultan al-Nasir and the Chinggisid princess Tulunbay and to analyze the impact of the termination of the marriage, according to medieval Arab chronicles. Research materials: medieval Arab chronicles of Mamluk authors: Ibn Duqmaq, al-Qalqashandi, al-Maqrizi, Mogultay, al-Nuwayri, Ibn Tagriberdi, al-Ayni et al. Results and novelty of the research: diplomatic relations between Egypt and the Golden Horde were the result of economic and foreign policy objectives of both states. Egypt at that time was one of the most powerful and influential states in the Muslim East, which showed an increased interest in events in the Golden Horde. This interest was stimulated by the fact that the Golden Horde was involved in the orbit of Islam and began to more intensively integrate Islam into the everyday culture of the Golden Horde society. After the Golden Horde had strengthened its position during the reign of khan Uzbek, Mamluk sultans began to consolidate even more their relations with the Golden Horde. One of the most important steps for the rapprochement between the two countries was a dynastic marriage between Mamluk Sultan al-Nasir and the Chinggisid princess Tulunbay. The object of this study is relevant, since the issue of political significance of dynastic relations between Mamluk and the Golden Horde rulers remain understudied. Meanwhile, the dynastic marriage is presented as a political act: as an expression of the good will of the state in relation to the other and a way to strengthen the influence of one country on another. The novelty of this research lies in the fact that, along with a detailed analysis of the Arab chronicles’ information on this subject, it presents for the first time the tomb of princess Tulunbay, which has been preserved in Egypt.

  8. “Who Began This Art? From Whence Did It Emerge?”: A Hermetic Frame Story on the Origins of Alchemy in Pseudo-Ibn Waḥshīya’s The Book of the Ziziphus Tree of the Furthest Boundary

    Full Text Available This paper explores the context of a Hermetic frame story in the pseudepigraphical alchemical treatise The Book of the Ziziphus Tree of the Furthest Boundary (Kitāb Sidrat almuntahā. The treatise is attributed to a prominent figure in the Arabic occult sciences, Abū Bakr b. Waḥshīya (fl. first half of the 4th/10th century. It was written in the form of a dialogue between the protagonist, Ibn Waḥshīya, and an alchemist from the Islamic West, al-Maghribī al-Qamarī. The last section of the introductory dialogue between these two characters consists of a frame story on the origins of alchemy and a legend of discovery (Fundlegende that introduces a cosmogony and an allegorical depiction of the process of transmutation. Both the frame story and the legend of discovery abound in Hermetic motifs and topoi known from other Greek and Arabic alchemical treatises. The exposition of the different prevailing theories on the beginnings of alchemy reflects, moreover, historical phenomena, such as the Graeco-Arabic translation movement and the shu‘ūbīya controversy. Consistent with the literary tradition of the Arabic Hermetica, Ancient Egypt emerges in this treatise as the cradle of alchemy; however, I suggest that more than merely literary convention, such evocations express a genuine fascination with Ancient Egypt and its surviving material culture. In this respect, the littleknown genre of Arabic books on hidden treasure might shed new light on common Hermetic narratives and their circulation in Arabic occult literature.

    Synopsis Genes linked to ALS susceptibility are being identified at an increasing rate owing to advances in molecular genetic technology. Genetic mechanisms in ALS pathogenesis appear to exert major effects in ~10% of patients, but genetic factors at some level may be important components of disease risk in most ALS patients. Identification of gene variants associated with ALS has informed concepts of the pathogenesis of ALS, aided the identification of therapeutic targets, facilitated research to develop new ALS biomarkers, and supported the establishment of clinical diagnostic tests for ALS-linked genes. Translation of this knowledge to ALS therapy development is ongoing. PMID:26515623

    One hundred and twenty-nine Grave's Basedow diseases in any gender and variable age patients, coming from several cities of Morocco, were randomized in a study of radio-iodine treatment who took place at the nuclear medicine department of Ibn Sina Hospital (Rabat, Morocco) during the period (from January 2001 to December 2008). The radio-iodine treatment was a first, second or third option and radio-iodine activities delivered varied (from 222 to 555 MBq 6 to 15 mCi) according to the age, the thyroid volume, the degree of hyperthyroidism and socio-economical situation. The high amounts of 131 I were reserved especially to the patients who live far and whose socio-economic level is low with an aim of quickly obtaining an easily controllable state of hypothyroidism by a substitute treatment. The results showed that: (1) 57.36% of patients reverted to euthyroidism (n = 74) with a patient having received two 131 I cures. The second cure was justified by recurrence of hyperthyroidism after the first cure; (2) 34.88% passed in hypothyroidism (n = 45) with three patients having received two cures of 131 I, the second cure was justified by recurrence of hyperthyroidism after the first cure in two patients and by the persistence of the hyperthyroidism after the first cure for the third patient. The average time of passage in hypothyroidism was 4.5 months; (3) 7.76% had remained in hyperthyroidism after the radioactive iodine treatment. Finally, 92.24% of our patients treated by radioactive iodine had passed in euthyroidism or hypothyroidism against 7.76% whose hyperthyroidism had persisted or occurred. (authors)

    Full Text Available Publication of Russian translations by V.G. Tiesenhausen of extracts from Arabic sources on the history of the Golden Horde was a breakthrough in this research topic. Thanks to the work of V.G. Tiesenhausen, Russian historical school has become one of the leading research schools and remains such to the present day. However, the work of V.G. Tiesenhausen does not exhaust the entire storehouse of medieval historical and geographical literature in the Arabic language, as he states in the preface to his work. Proof of this is the fact that in voluminous work of V.G. Tiesenhausen we practically do not meet materials from the writings of historians dealing with the narrative biographies, although their works contain very valuable information about the history of the Golden Horde. As examples of such works, we can name the following: 1 al-Safadi (696 AH / 1297 – 764 AH / 1363, “Al-Wafi bi al-vafiyat” (الوافي بالوفياب أو تاريخ الصفدي (Complete Collection of Biographies of Deceased Persons or the History of al-Safadi; 2 al-Safadi (696 AH / 1297 – 764 AH / 1363, (أعيان العصر وأعوان النصر (Outstanding Personalities of this century, and the Champions of Victory; 3 al-Kutubi Muhamamd Shakir (d. 764 AH, (فوات الوفيات و الذيل عليها (Biographies of Deceased Persons not included (in the collection of Ibn Hallikan (608 AH / 1211 – 681 AH / 1282, and addition to them; 4 (al-Maqrisi Taqi al-Din (d. 845 AH, (كتاب المقفّى الكبير (Great Rhymed Book; 5 al-Asqalani Ibn Najar (d. 852 AH (الدرر الكامنة في أعيان المائة الثامنة (Hidden Pearls in a Biography of Outstanding Persons of the eighth century of Hijra; 6 Ibn Taghribirdi (813–874 AH (المنهل الصافي المستوفي بعد الوافي (Pure Completing Source after the “Full”.

  15. Final Environmental Statement related to the operation of Wolf Creek Generating Station, Unit No. 1. Docket No. STN 50-482, Kansas Gas and Electric Company, et al

    International Nuclear Information System (INIS)

    1982-06-01

    This final environmental statement contains the second assessment of the environmental impact associated with operation of Wolf Creek Generating Station Unit 1 pursuant to the National Environmental Policy Act of 1969 (NEPA) and 10 CFR Part 51, as amended, of the NRC's regulations. This statement examines: the affected environment, environmental consequences and mitigating actions, and environmental and economic benefits and costs. Land use and terrestrial- and aquatic-ecological impacts will be small. Air-quality impacts will also be small. However, steam fog from the station's cooling lake has the potential for reducing visibility over nearby roads and bridges. A fog-monitoring program for roads and bridges near the lake has been recommended. Impacts to historic and prehistoric sites will be negligible. Chemical discharges to the Neosho River are expected to have no appreciable impacts on water quality under normal conditions and will be required to meet conditions of the station's NPDES permit. The effects of routine operations, energy transmission, and periodic maintenance of rights-of-way and transmission line facilities should not jeopardize any populations of endangered or threatened species. No significant impacts are anticipated from normal operational releases of radioactivity. The risk associated with accidental radiation exposure is very low. The net socioeconomic effects of the project will be beneficial. The action called for is the issuance of an operating license for the Wolf Creek Generating Station Unit 1

    The draft version of the environmental impact statement, EPA No. 860106D, deals with licensing a startup of Units 1 and 2 of the South Texas Project, both pressurized water reactors. The plant will permanently eliminate over 3000 acres of farmland and affect another 6000 acres of neighboring farmland. It will discharge cooling water into the Colorado River. Mitigation plans call for 1700 acres of bottom land to become a wildlife preserve and for no use of herbicides in grazing areas. Positive impacts will be increased employment for the area with a corresponding increase in revenues. Negative impacts may be changes in marsh productivity and species composition. There may be a loss of habitat for the American alligator. Risks associated with the accidental release of radiation are rated as very low. The Federal Water Pollution Control Act of 1972 and Nuclear Regulatory Commission Licensing provide legal mandates

    A draft version of the environmental impact statement (EPA No. 840331D) concerns the proposal to issue an operating license for Unit 3 of the Millstone Nuclear Power Station on Connecticut. The plant would use a four-loop pressurized water reactor to produce up to 3579 MW of thermal energy and a calculated maximum electric output of 1209 MW of electric power. A new line would require clearing about 350 acres. Positive impacts include the addition of new capacity, which would benefit the area economically and employment opportunities. Negative impacts include the loss of some winter flounder, which would be minimized by a fish return system, and some increases in the concentration of chemical constituents that would enter Long Island Sound. Policies relating to coastal areas, water pollution, and reactor regulation provide a legal mandate for the impact statement

    human settlements and occupation, it is possible to characterize a threefold transition: first, the former transition between the pre-Islamic prehistoric societies and the development of Muslim societies; second, the more recent transition between the traditional historical society (farmers) and the contemporary society, characterized by the growth of urbanization, the creation of modern transport infrastructure and the concomitant growth of tourist flows; third, the current transition between the yesterday and tomorrow Al Ain City, due to the transformation of a local town centred on national economics all along the second half of the twentieth century, into an international town more open to the wider world with the management of a possible increased 20 % of tourist flow because of the inscription of Cultural Sites of Al Ain on the UNESCO's World Heritage List. It is not possible to completely ignore the fact that the Jebel Hafit and its foothills are partly crossed by an international boundary. In case of political tensions, this may cause some difficulties for the management of this territory, with contradictory requirements between security, tourism, traditional land use, and scientific research.

    Full Text Available Background:Pseudomonas aeruginosa is a severe challenge for antimicrobial therapy, because of chromosomal mutations or exhibition of intrinsic resistance to various antimicrobial agents such as most β-lactams. We undertook this study to evaluate the existence of SME, AIM and VIM metallo-beta lactamases encoding genes among P. aeruginosa strains isolated from ICU patients in AL- Zahra Hospital in Esfahan-Iran.Methods : In a retrospective cross sectional study that was conducted between March 2012 toApril 2013, in total 48 strains of P. aeruginosa were collected from clinical specimens of bedridden patients in ICU wards. Susceptibility test was performed by disc diffusion method.All of the meropenem resistant strains were subjected to modified Hodge test (MHT for detection of carbapenemases. Multiplex PCR was performed for detection of VIM, blaAIM,blaSME genes.Results : In disk diffusion method imipenem and meropenem showed the most and colistin the least resistant antimicrobial agents against P. aeruginosa strains. Of the 48 isolates 36, (75% were multidrug resistant. Amplification of β –lactamase genes showed the presence of blaVIM genes in 7 (%14.6 strains. All of the isolates were negative for blaSME and blaAIM genes. We ouldn’t find any statistically significance diffe rence among presence of this gene and MDR positive, age or source of the specimen.Conclusion : As patients with infections caused by MBL-producing bacteria are at an intensified risk of treatment failure, fast determination of these organisms is necessary. Our findings may rovide useful insights in replace of the appropriate antibiotics and may also prevent MBLs mediated resistance problem.

    Full Text Available In 924 an army headed by the emir ‘Abd al-Raḥmān III crossed the border of the emerging kingdom of Pamplona and devastated its territory. Two chroniclers, ‘Arīb b. Sa‘īd and Ibn Ḥayyān, recorded in their texts the names of several of the places that were attacked. The first edition and translation of ‘Arīb’s text in the late 19th and early 20th centuries probed to be of great importance, since not only provided the basis for the appearance of some studies focused on the identification of the place-names, but it also greatly influenced the edition and translation of the Ibn Ḥayyān’s manuscript, published several decades later. Nonetheless, the comparison between ‘Arīb’s manuscript and its edition has shown important differences between the place-names that appear in both of them. The main purpose of these pages is to restore the place-names to their original handwritten form in order to make possible new hypothesis on their identification.En el año 924, un ejército dirigido por el emir ‘Abd al-Raḥmān III cruzaba las fronteras del incipiente Reino de Pamplona y sometía su territorio a devastación. Dos cronistas, ‘Arīb b. Sa‘īd e Ibn Ḥayyān, recogieron en sus textos los nombres de varios de los lugares asolados. La aparición de la edición y traducción del texto de ‘Arīb a finales del siglo XIX y principios del XX tuvo un peso muy destacado: primero, porque sirvieron de base para la aparición de estudios centrados en la identificación de los topónimos, pero además, por su influencia en la edición y traducción del texto de Ibn Ḥayyān, publicada décadas más tarde. El cotejo del texto manuscrito de ‘Arīb con su edición, sin embargo, nos ha permitido constatar que existen importantes diferencias entre los topónimos que figuran en uno y otro.

    Full Text Available In the Islamic period, Apollonius of Tyana (c. 15-100 CE was well known both as “Lord of the Talismans” (ṣāḥib al-ṭilasmāt and as a Neo-Pythagorean-Hermetic philosopher. In his Kitāb al-Aḥjār, Jābir b. Ḥayyān cites “the Muslim advocates of Apollonius” (aṣḥāb Balīnās al-Islāmīyūn. The reference shows that Apollonius’ most prominent work, Sirr alkhalīqa, was already famous in the Arabicspeaking world from very early on. This article gives an overview of citations of Apollonius in Islamic sources from different fields and of the works generally attributed to him. Furthermore, I review Sirr al-khalīqa, its influences on the Jābirian works and its reception in the Ismā‘īlī tradition. This article additionally discusses an Arabic commentary of Sirr al-khalīqa by ‘Awn b. al-Mundhir (4th/10th century, which is extant in a unique manuscript, and its hitherto unknown Persian translation. This Persian translation covers parts of Ibn al-Mundhir’s work not available in the Arabic excerpt and is therefore an important source for the history of Islamic alchemy. An edition of the Persian translation is given as an appendix.

    Introduction L'incidence des complications respiratoires postopératoires (CRPO) reste très diversement appréciées selon les critères diagnostiques retenues dans les différentes études, ce qui la fait varier de 5 à plus de 50%. Les CRPO majeurs après chirurgie de l'aorte abdominale sont responsables d'une grande morbi-mortalité pouvant aller jusqu’à 36%, d'une durée d'hospitalisation et d'un coût plus importants. Ainsi dans l'optique d'améliorer notre prise en charge périopératoire de la chirurgie de l'aorte, nous avons décidé de mener une étude pour dresser le profil épidémiologique et déterminer les facteurs de risque des complications respiratoires dans notre contexte Méthodes Il s'agit d'une étude de cohorte rétrospective du mois de Janvier 2007 au mois de décembre 2011 portant sur l'ensemble des patients opérés pour pathologie aortique au bloc opératoire central de l'hôpital Ibn Sina de Rabat, Maroc. Résultats Cent vingt cinq patients ont été inclus dans notre étude, 24 patients ont été opérés pour anévrysme de l'aorte abdominale et 101 patients pour lésion occlusive aortoiliaque. Dans notre série 22 malades soit 17,6% ont présenté une complication respiratoire majeure avec, une reventilation dans 4,8% des cas, une difficulté de sevrage de la ventilation artificielle dans 3,2% des cas, une pneumopathie dans 4% des cas, un syndrome de détresse respiratoire aigue (SDRA) dans 4% des cas et une nécessité de fibroaspiration bronchique dans 1,6% des cas. En analyse univariée: l’âge, la présence d'une BPCO avec dyspnée stade 3 ou 4, la présence d'une anomalie à l'EFR préopératoire, la présence d'un stade avancé (III ou IV) de LOAI et la reprise chirurgicale étaient statistiquement associés à la survenue d'une complication respiratoire postopératoire. En analyse multivariée, seule une anomalie à l'EFR en préopératoire constituait un facteur de risque indépendant de survenue d'une complication

    Full Text Available Abstract Definition of the disease AL amyloidosis results from extra-cellular deposition of fibril-forming monoclonal immunoglobulin (Ig light chains (LC (most commonly of lambda isotype usually secreted by a small plasma cell clone. Most patients have evidence of isolated monoclonal gammopathy or smoldering myeloma, and the occurrence of AL amyloidosis in patients with symptomatic multiple myeloma or other B-cell lymphoproliferative disorders is unusual. The key event in the development of AL amyloidosis is the change in the secondary or tertiary structure of an abnormal monoclonal LC, which results in instable conformation. This conformational change is responsible for abnormal folding of the LC, rich in β leaves, which assemble into monomers that stack together to form amyloid fibrils. Epidemiology AL amyloidosis is the most common type of systemic amyloidois in developed countries with an estimated incidence of 9 cases/million inhabitant/year. The average age of diagnosed patients is 65 years and less than 10% of patients are under 50. Clinical description The clinical presentation is protean, because of the wide number of tissues or organs that may be affected. The most common presenting symptoms are asthenia and dyspnoea, which are poorly specific and may account for delayed diagnosis. Renal manifestations are the most frequent, affecting two thirds of patients at presentation. They are characterized by heavy proteinuria, with nephrotic syndrome and impaired renal function in half of the patients. Heart involvement, which is present at diagnosis in more than 50% of patients, leading to restrictive cardiopathy, is the most serious complication and engages prognosis. Diagnostic methods The diagnosis relies on pathological examination of an involved site showing Congo red-positive amyloid deposits, with typical apple-green birefringence under polarized light, that stain positive with an anti-LC antibody by immunohistochemistry and

    Full Text Available Abstract ‘Abdullah bin al-Mubark was born in Marw’ one of the prime cities in Khurasan, (nowadays in the surroundings of Afghanistan and Central Asia, in the year 118 AH. In addition to his many talents, achievements and abilities, ‘Abdullah bin al-Mubarak was also gifted in literacy, particularly in the art of poetry. He held an eloquent tongue which was recognized by all who conversed with him and his language displayed the nature of someone who had been taught well. Most of the poetry which has been recorded from him is actually his advice to others, whether they were close friends or high-ranking Caliphs and Rulers. The topics spoken of concerned the common issues which had arisen in his time (e.g. matters pertaining to theology, politics, the worldview, the community etc and as always, they contained much wisdom and hence the books of history have sealed them and recorded them. This research article discussed Biography of Abdullah ibn Al Mubarak, The Islamic Ethics in his poetry,\tImpact of Rhetoric on his poetry with special concentration on the four kinds i.e. citation, impact of Quranic words, Quranic pictorial and Quranic style on his poetry.

    Full Text Available The main object of this article is to translate, scrutinize the contents and reveal the sources of two Hebrew astrological texts embedded in the commentary on Sefer Yeṣirah composed by Yehudah ben Barzilay, the leading Rabbinic authority in Barcelona in the first half of the 12th century. The first text arises great interest because it incorporates the first ever known horoscopic chart written in Hebrew. The second text includes a miscellany of cosmological and astrological theories. The analysis of both fragments reveals the reception of astrological texts by Jewish intellectuals in the Iberian Peninsula. In contrast with Abraham bar Ḥiyya and Abraham Ibn 'Ezra, who epitomize a renovating trend couching into a Hebrew mold various aspects of Greek and Arabic science, Ben Barzilay embodies a conservative trend which exclusively relies on Jewish astrological and scientific sources.Este artículo tiene como principal propósito traducir, estudiar los contenidos y descubrir las fuentes de dos textos astrológicos hebreos conservados en el comentario al Sefer Yeṣirá de Yehudá ben Barzilay, la principal autoridad rabínica de Barcelona en las primeras décadas del siglo XII. El primer texto despierta gran interés porque incorpora el primer horóscopo documentado escrito en lengua hebrea conocido. El segundo texto incorpora una miscelánea de teorías cosmológicas y astrológicas. El análisis de ambos fragmentos revela un caso especial de recepción de fuentes astrológicas y científicas por intelectuales judíos en la península Ibérica. En claro contraste con Abraham bar Ḥiyya y Abraham Ibn 'Ezra, que encarnan una corriente renovadora orientada a verter al hebreo diversos aspectos de la astrología y ciencia griega y árabe, Yehudá ben Barzilay representa una modalidad conservadora inclinada a la utilización de fuentes astrológicas y científicas de autores exclusivamente judíos.

    Summary La main est fréquemment exposée aux brûlures, entraînant des séquelles esthétiques et fonctionnelles. Le traitement de ces séquelles est surtout chirurgical et consiste en la greffe de peau, dont le type dépend de la localisation de la brûlure et du type des séquelles. Dans ce travail rétrospectif, nous rapportons une série de 152 cas de brûlures des mains colligés au service de chirurgie plastique du Centre Hospitalier Universitaire Ibn-Sina de Rabat sur une période de dix ans, allant de 1998 à 2007. Les indications thérapeutiques dépendent du type de séquelles et de la localisation de la brûlure. En tout, 97 patients ont bénéficié d'une greffe cutanée, dont 76% par greffe de peau totale, 21% par greffe de peau demi-épaisse et 3% par peau fine. Les séquelles des brûlures des mains posent un problème thérapeutique majeur, malgré la diversité des procédés chirurgicaux, d'où l'intérêt de la prévention. PMID:21991196

    formulation of a controller feedback multivariable is presented, designed with the combination of the technologies of fuzzy logic and neural networks with the purpose of improving the control of speed, power and temperature of the UTG. This proposed control is used in conjunction with the scheme of conventional control of the existent UTG, to integrate a strategy of control hybrid feedback. The control feedback is compound for a fuzzy inference system of multiple entrances and a left exit designed with entrance data and exit of the plant. The controller feed forward is compound for conventional controllers type PI in this type of units. With this strategy, the controller feedback provides a bigger contribution in the control sign the effort of the conventional controllers' PI control and the strong interaction that it exists among them diminishing. The controllers PI feed forward contribute a smaller control sign used for fine adjustments in the control sign.

    The disordered crystal structure of 20H-AlON (Al 10 O 3 N 8 ) was determined by combined use of X-ray powder diffraction and transmission electron microscopy. The title compound is hexagonal with space group P6 3 /mmc (Z=2) and the unit-cell dimensions are a=0.307082(5) nm, c=5.29447(8) nm and V=0.432376(12) nm 3 . The structural model showed the positional disordering of three of the six Al sites in the unit cell. The reliability indices calculated from the Rietveld method were R wp =6.97%, S (=R wp /R e )=1.68, R p =5.45%, R B =5.13% and R F =4.56%. We interpreted the disordered structure of 20H-AlON as a statistical average of six different types of ordered structural configurations, which are composed of an octahedral [Al(O, N) 6 ] layer and tetrahedral [Al(O, N) 4 ] layers. We demonstrated the high correlations between the hexagonal unit-cell dimensions and the octahedral layer concentrations for AlON and SiAlON polytypoids. - Graphical abstract: Variations of a and c/(n O +n T ) with n O /(n O +n T ). The a and c are the hexagonal unit-cell dimensions of AlON, SiAlON and AlN. The n O and n T are, respectively, the numbers of octahedral and tetrahedral layers in the unit cells. The unit-cell dimensions in literature are plotted in black plus for AlON and black cross for SiAlON. The unit-cell dimensions of AlN are a=0.3110 nm and c=0.4980 nm. - Highlights: • Crystal structure of Al10O3N8 is determined by laboratory X-ray powder diffraction. • The atom arrangements are represented by the split-atom model. • Six types of ordered atom arrangements are derived from the disordered structure. • Hexagonal unit-cell dimensions changed systematically for AlON and SiAlON compounds

    Nofal Faris

    2016-01-01

    Full Text Available The present article is devoted to research in genesis and evolution of views of medieval thinker Ahmad b. al-Ha’it (d. 847. Being a unique figure for his time, Ibn al-Ha’it played a significant role in the formation of Arabic philosophy, which, unfortunately, is ignored to this day by specialists-medievalists: so, for the first time in the history of intellectual thought of the medieval Middle East, the Mu’tazilli philosopher made an attempt of an exit from a strict theologism of Kalam to the tradition, which was issued in Falsafah. Justification of the reincarnation theory within the Islamic theological field which is initially constructed on postulates of singularity and an extremity of any terrestrial human life became a separate merit of Ahmad. Along with it, the thinker attracted the arianistic doctrine, which allowed by him to develop his own Christology and ontology in neoplatonic paradigmatics. Thereby, the pupil of a great Basrian thinker Ibrahim b. Sayyar an-Nazzam anticipated the great synthesis of Kalam and Arabic peripatetizm realized by late Ash’arites — al-Ghazali (d. 505/1111, Fakhruddin ar-Razi (d. 606/1210 and ʻUdud ad-Din al-Iji (d. 756/1355.

    2009-06-01

    Full Text Available Jābir b. Aflaḥ al-Ishbīlī, known as Geber filius Afflay Hispalensis in medieval Western Europe, was a mathematician and theoretical astronomer who most probably flourished in Seville during the first quarter of the 12th century. Jābir b. Aflaḥ was a leading figure in medieval astronomy thanks to the Iṣlāḥ al-Majisṭī, his magnum opus, which was translated into Latin and Hebrew. With his Iṣlāḥ al-Majisṭī, Jābir b. Aflaḥ intended to rewrite the Almagest and introduced some corrections to it. In his important paper «The Andalusian revolt against Ptolemaic astronomy» published in 1984, the renowned scholar A.I. Sabra drew attention to a group of Andalusian philosophers who where contemporaries of Jābir b. Aflaḥ or flourished shortly after him, such as Ibn Bājja (d. 537/1138, Ibn Ṭufayl (d. 581/1185, Ibn Rushd (d. 595/1198, Maimonides (d. 601/1204 and al-Biṭrūjī(fl. 596/1200. Sabra stressed their cosmological criticisms of the astronomical models described in the Almagest arising from the lack of consistency of Ptolemy’s models with Aristotle’s physics. The purpose of this paper is to describe Jābir b. Aflaḥ’s criticisms of Ptolemy in order to consider whether he should be placed among the members of the Andalusian revolt against Ptolemaic astronomy. The final conclusion is that Jābir b. Aflaḥ’s criticisms are not themselves cosmological — although they may have cosmological implications — but of a completely technical mathematical nature. He should not, therefore, be placed among the members of the Andalusian revolt against Ptolemaic astronomy.

    Ŷābir b. Aflaḥ al-Išbīlī, conocido como Geber filius Afflay Hispalensis en la Europa medieval, fue un matemático y astrónomo teórico que probablemente floreció en Sevilla durante el primer cuarto del s. XII. Ŷābir b. Aflaḥ es un astrónomo medieval importante gracias a su obra

    Wettability and interfacial interaction of the Ta2O5/Cu-Al system were studied. Pure Cu does not wet the Ta2O5 substrate, and improved spreading is achieved when relatively a high fraction of the active element (~40 at.% Al) was added. The Al2O3 and AlTaO4 phases were observed at the Ta2O5/Cu-Al interface. A thermodynamic evaluation allowed us to suggest that the lack of wetting bellow 40 at.% Al is due to the presence of a native oxide, which covers the drop. The conditions of the native oxide decomposition and the formation of the volatile Al2O suboxide strongly depend on the vacuum level during sessile drop experiments and the composition of the Cu-Al alloy. In our case, Al contents greater than 40% provides thermodynamic conditions for the formation of Al2O (as a result of Al reaction with Al2O3) and the drop spreading. It was suggested that the final contact angle in the Ta2O5/Cu-Al system (50°) is determined by Ta adsorption on the newly formed alumina interlayer.

This statement examines: the effected environment, environmental consequences and mitigating actions, and environmental and economic benefits and costs. Land use and terrestrial and aquatic-ecological impacts will be small. Operational impacts to historic and archeological sites will be negligible. The effects of routine operations, energy transmission, and periodic maintenance of rights-of-way and transmission facilities should not jeopardize any populations of endangered or threatened species. No significant impacts are anticipated from normal operational releases of radioactivity. The risk associated with accidental radiation exposure is very low. The net socioeconomic effects of the project will be beneficial. The action called for is the issuance of an operating license for Seabrook Station, Units 1 and 2

    Science.gov (United States)

    Smith, Nathan

    Supernovae that show evidence of strong shock interaction between their ejecta and pre-existing slower circumstellar material (CSM) constitute an interesting, diverse, and still poorly understood category of explosive transients. The chief reason they are extremely interesting is because they tell us that in a subset of stellar deaths, the progenitor star becomes wildly unstable in the years, decades, or centuries before explosion. This is something that has not been included in standard stellar evolution models but may significantly change the end product and yield of that evolution and complicates our attempts to map SNe to their progenitors. Another reason they are interesting is because CSM interaction is an efficient engine for making bright transients, allowing superluminous transients to arise from normal SN explosion energy, and transients of normal supernova luminosity to arise from sub-energetic explosions or low radioactivity yield. CSM interaction shrouds the fast ejecta in bright shock emission, obscuring our view of the underlying explosion, and the radiation hydrodynamics is challenging to model. The CSM interaction may also be highly nonspherical, perhaps linked to binary interaction in the progenitor system. In some cases, these complications make it difficult to tell the difference between a core-collapse and thermonuclear explosion or to discern between a nonterminal eruption, failed supernova, or weak supernova. Efforts to uncover the physical parameters of individual events and connections to progenitor stars make this a rapidly evolving topic that challenges paradigms of stellar evolution.

    Full Text Available En los Estados Unidos de América se ha logrado una disminución de la exposición a plomo de la población en general, gracias al establecimiento de diversas normas. En este artículo se destaca parte de los conocimientos adquiridos a través de la experiencia obtenida en este país en materia de plomo, en particular respecto al aire y al agua. Uno de los aspectos fundamentales es la posibilidad de contar con una base científica sólidamente establecida y claramente entendida, a partir de la cual se tomarán las medidas correspondientes. Los efectos secundarios de ciertas normas concernientes al aire ponen de manifiesto de qué manera los esfuerzos orientados a solucionar un problema pueden aportar beneficios en otras áreas, si bien pueden surgir consecuencias no deseadas, debido a la falta de previsión y de evaluación. Asimismo, en este documento se discuten las diferencias entre los enfoques centralizados y los descentralizados para el manejo de la exposición a plomo.Lead regulations and standards have resulted in a lower exposure to lead in the general population of the United States of America. This paper highlights some of the know-how developed through lead-containing experiences, particularly regarding lead content in air and water. The availability of a solid and clear scientific knowledge is central to the success of these policies. Collateral effects of some air-related standards show the extent to which problem-oriented efforts may be beneficial in other areas, inasmuch as they may have untoward consequences if careful planning and evaluation are not considered. Finally, this paper presents a discussion of the differences between centralized and decentralized approaches to lead exposure control.

  2. 27Al MAS NMR spectroscopic identification of reaction intermediates in the carbothermal reduction and nitridation of alumina

    2010-01-01

    The reaction intermediates in the carbothermal reduction and nitridation (CRN) reaction of γ-Al 2 O 3 were identified by 27 Al magic-angle spinning (MAS) nuclear magnetic resonance (NMR) spectroscopy. This identification ruled out the possibility of a reaction mechanism involving the gaseous reaction intermediates. In the CRN reaction of γ-Al 2 O 3 , AlO 4 units were converted to AlN stepwise via AlN x O 4-x (x = 1, 2, 3) intermediates, while AlO 6 units were more slowly converted to AlN than AlO 4 units and the NMR peaks of partially nitridated AlO 6 units were not detected. The NMR peak intensities of partially nitridated AlO 4 units became weaker with increasing reaction temperature.

    In the year 2001, in Stuttgart (Federal Republic of Germany) the first office building was established which uses a thermal construction unit activation with air as cooling agent. Today, the system ''Concret-cool'' already is installed in more than 40 buildings. Computations show that due to the room heating by means of internally finned ventilation pipes embedded in concrete more than 50 % less energy in comparison to comparable systems can be used. In his Green Building project ''Skyline Tower'' in Munich (Federal Republic of Germany), also star architect Helmut Jahn uses the know-how of the manufacturer of ventilation systems from Stuttgart. As one of the first multi-storied buildings in Munich, ''Skyline Tower'' with its 23 floors was prized with the pre-certificate of the German quality seal ''sustainable building ''in gold.

    Gas turbines (GT) are high risk systems that operate at high velocities, temperatures and pressures. These conditions establish very strict requirements for the control system, reason why it is required a high automation level to obtain a safe and profitable operation. The control system of the turbo-gas units (TGU) is based on conventional control algorithms of type PI. This control scheme is destined for regulation and rejection of disturbance tasks, and not to follow reference points. All the controllers act on a single valve control, which represents a strong interaction between them. An alternative to treat this interaction and to improve the performance of the turbo-gas unit is the use of intelligent control techniques, adopting a pre-feedback scheme. The feedback control and the pre-feedback one are combined so that the first one assures the regulation around the operation points (for example, the synchronism velocity) and the second, provides the pursuit of the demanded trajectories established by the system. [Spanish] Las turbinas de gas (TG) son sistemas de alto riesgo que operan a altas velocidades, temperaturas y presiones. Estas condiciones establecen requerimientos muy estrictos para el sistema de control, por lo que se requiere en alto nivel de automatizacion para lograr una operacion segura y rentable. El sistema de control de las unidades turbogas (UTG) esta basado en algoritmos de control convencionales del tipo PI. Este esquema de control es destinado para tareas de regulacion y rechazo a perturbaciones, y no para seguimiento de puntos de referencia. Todos los controladores actuan sobre una sola valvula de control, lo que representa una fuerte interaccion entre los mismos. Una alternativa para tratar esta interaccion y mejorar el desempeno de la unidad turbogas es el empleo de tecnicas de control inteligente, adoptando un esquema retro-prealimentado. El control retroalimentado y el prealimentado se combinan para que el primero asegure la

    Full Text Available Das Interview ist nach wie vor das beliebteste sozialwissenschaftliche Verfahren des Datengewinns. Ökonomie der Erhebung, Vergleichbarkeit und die Möglichkeit, Einsicht in Praxisbereiche und historisch-biografische Dimensionen zu erhalten, die der direkten Beobachtung kaum zugänglich sind, machen seine Attraktivität aus. Zugleich mehren sich Kritiken, die seine Leistungsfähigkeit problematisieren, indem sie auf die begrenzte Reichweite der Explikationsfähigkeiten der Befragten, die Reaktivität der Erhebung oder die Differenz zwischen Handeln und dem Bericht über Handeln verweisen. Im Beitrag wird zwischen Ansätzen, die das Interview als Text, und solchen, die es als Interaktion verstehen, unterschieden. Nach dem Text-Verständnis werden Interviews unter inhaltlichen Gesichtspunkten analysiert und als Zugang zu einer vorgängigen sozialen oder psychischen Wirklichkeit angesehen. Das Interaktions-Verständnis versteht Interviews dagegen als situierte Praxis, in welcher im Hier und Jetzt von InterviewerInnen und Befragten gemeinsam soziale Sinnstrukturen hergestellt werden. Anhand ubiquitärer Phänomene der Interviewinteraktion – Fragen, Antworten und die Selbstpositionierung von InterviewerInnen und Befragten – werden Praktiken des interaktiv-performativen Handelns im Interview dargestellt. Ihre Relevanz für die Interviewkonstitution und ihre Erkenntnispotenziale für die Interviewauswertung werden aufgezeigt. Es wird dafür plädiert, die interaktive Konstitutionsweise von Interviews empirisch zu erforschen und methodisch konsequent zu berücksichtigen.

    2015-09-01

    The present experiment was carried out in order to know the resistance mechanism of the ectomycorrhizal (ECM) fungi under Al stress, to establish the theoretical foundation to alleviate the Al toxicity of trees, to guide the selection of Al-resisted ECM fungi and preserve forest health. The absorption and assimilation of Al3+ by four ECM fungi [Pisolithus tinctorius (Pt 715), Suillus luteus (Sl 08 and Sl 14), Gyroporus cyanescens (Gc 99)], which were isolated from different forest soils, were investigated in pure culture in liquid media. The growths of Pt 715 and Sl 08 were less affected by Al3+, but growths of S114 and Gc 99 were obviously inhibited by Al3+. With the increasing of Al3+ concentration in culture, the absorption and assimilation of Al3+ by four ECM fungi increased. It indicated that the concentration of Al3+ in environments might be the primary factor determining the Al3+ content in the cell of each tested fungi. Amounts of Al3+ absorbed (in total or calculated in unit hyphae) by the Al3+ tolerant strains (Pt 715 and Sl 08) were significantly lower than those by the Al3+ sensitive strains (S1 14 and Gc 99), which illustrated that reducing the absorption of Al3+ under Al3+ stress environment might be an effective approach to alleviate the Al3+ poison for these Al3+ tolerant strains. Furthermore, Al3+ stress could stimulate the ECM fungi to assimilate more N, P, and K, which might indicate that increasing requirement of the nutrients also could be helpful for ECM fungi to fight against the harmful effects caused by Al3+ stress.

    Full Text Available This article analyses the corpus of 900 documents in the Mamlūk Haram al-Šarīf collection from the angle of archival storage. The vast majority of these documents are linked to the Jerusalem judge Šaraf al-Dīn ,Īsā b. Ġānim and to his period in office between the years 793/1391 and 797/1395. The sample of surviving documents, primarily estate inventories but also a few documents from other areas of the law within the qādī’s competence, contradicts the assumption that the Haram corpus is a systematically compiled archive of qādī records. Court certifications of real-estate sales and further transactions that are preserved for other periods within the Haram corpus are totally absent for this particular period. There is, moreover, an abundant number of documents concerning financial transactions in institutions over which the judge had jurisdiction. The necrology of the contemporary chronicler Ibn Hiğğī (d. 816/1413 opens an interesting perspective to explain the selection of documents relating to Šaraf al-Dīn, who was involved in a massive corruption case.

In turn, the author of this article emphasizes that the philosophical and scientific heritage of the Crimean Khanate represents now a vital interest to researchers, above all, due to the fact that there was a significant flourishing of cultural life on the territory of Crimea and other regions of the Northern Black Sea in the 15th–17th centuries. Among other things, it should be paid special attention to the study of the development of “rational sciences”, including philosophical knowledge. In this context, the author refers to the heritage of the scholar from the Golden Horde, namely Sharaf al-Qrimi (d. 1440. His life falls on a very interesting and, in general, poorly studied period in the history of the Crimea, namely, at a time when the Crimean Yurt (Qırım Yurtu had not yet been an independent State and was a part of the Golden Horde. Creative heyday of this scientist coincided with the age of the weakening of the Golden Horde power in the Crimean yurt, which stood out in an independent State (“Khanate”, hanlığı only in 1441, during the reign of Haji Giray (d. 1466. The works of Sharaf al-Qrimi dedicated to the hermeneutics, provides a clear picture not only of some issues of Post-Classical Islamic thought, but also the development of Islamic knowledge in the Eastern European lands (in particular, in Crimea, which experienced the intensive inter-cultural transmission during the Golden Horde times. It is argued, that Sharaf al-Qrimi was under the influence of the Central Asian and Persian philosophical theology, inspired by the works of Abu ‘Ali ibn Sina and his followers. It is showed that in Crimean (and also early Ottoman context Islamic Philosophy continued

    γ-AlD 3 was synthesized from LiAlD 4 and AlCl 3 via thermal decomposition of aluminum hydride etherate in presence of excess LiAlD 4 . γ-AlD 3 was determined by powder neutron diffraction and synchrotron X-ray diffraction to crystallize in the space group Pnnm. The orthorhombic structure has unit-cell dimensions a = 7.3360(3) A, b = 5.3672(2) A and c = 5.7562(1) A, and it consists of both corner- and edge-sharing AlD 6 octahedra where each hydrogen is shared between two octahedra. The average Al-D distances in octahedra with edge-sharing is 1.706 A and in the octahedra with only corner-sharing 1.719 A

    Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative motor neuron disease accompanied by both systemic and central nervous system-specific inflammation as well as deregulated energy metabolism. These potential pathogenetic factors have recently been found to mutually interact with the gut microbiota, raising the hypothesis of a link between microbiome alterations and ALS pathogenesis. The aim of our study was to assess whether ALS is associated with an altered composition of the fecal microbiota. We compared the fecal microbiota of 25 ALS patients with 32 age- and gender-matched healthy persons using 16S rRNA gene sequencing analysis. Confounding factors and secondary disease effects on the microbiome were minimized by selection of patients without dysphagia, gastrostomy, noninvasive ventilation, or reduced body mass index. Comparing the 2 carefully matched groups, the diversity and the abundance of the bacterial taxa on the different taxonomic levels as well as PICRUSt-predicted metagenomes were almost indistinguishable. Significant differences between ALS patients and healthy controls were only observed with regard to the overall number of microbial species (operational taxonomic units) and in the abundance of uncultured Ruminococcaceae. Conclusively, ALS patients do not exhibit a substantial alteration of the gut microbiota composition. Copyright © 2017 Elsevier Inc. All rights reserved.

    Original detector unit of the Instituut voor Kernfysisch Onderzoek (IKO) BOL project. This detector unit shows that silicon detectors for nuclear physics particle detection were already developed and in use in the 1960's in Amsterdam. Also the idea of putting 'strips' onto the silicon for high spatial resolution of a particle's impact on the detector were implemented in the BOL project which used 64 of these detector units. The IKO BOL project with its silicon particle detectors was designed, built and operated from 1965 to roughly 1977. Detector Unit of the BOL project: These detectors, notably the ‘checkerboard detector’, were developed during the years 1964-1968 in Amsterdam, The Netherlands, by the Natuurkundig Laboratorium of the N.V. Philips Gloeilampen Fabrieken. This was done in close collaboration with the Instituut voor Kernfysisch Onderzoek (IKO) where the read-out electronics for their use in the BOL Project was developed and produced.

    Everybody at Lawrence Berkeley Laboratory's Center for Beam Physics is pleased with the rapid progress in commissioning LBL's Advanced Light Source (ALS) electron storage ring, the foundation for this third-generation synchrotron radiation facility. Designed for a maximum current of 400 mA, the ALS storage ring reached 407 mA just 24 days after storing the first beam on 16 March. ALS construction as a US Department of Energy (DOE) national user facility to provide high-brightness vacuum ultra-violet and soft x-ray radiation began in October 1987. One technical requirement marking project completion was to accumulate a 50-mA current in the storage ring. The ALS passed this milestone on 24 March, a week ahead of the official deadline. Once injected, the electron beam decays quasi-exponentially primarily because of interactions with residual gas molecules in the storage-ring vacuum chamber. Eventually, when the pressure in the vacuum chamber with beam decreases toward the expected operating level of 1 nano Torr, it will only be necessary to refill the storage ring at intervals of four to eight hours. At present the vacuum is improving rapidly as surfaces are irradiated (scrubbed) by the synchrotron radiation itself. At 100 mA, beam lifetime was about one hour (9 April)

    The change in the microstructural parameters and microhardness values in 6.5 MeV proton irradiated pure Al and Al5083 alloy samples have been evaluated using different model based techniques of X-ray diffraction Line Profile Analysis (XRD) and microindendation techniques. The detailed line profile analysis of the XRD data showed that the domain size increases and saturates with irradiation dose both in the case of Al and Al5083 alloy. The corresponding microstrain values did not show any change with irradiation dose in the case of the pure Al but showed an increase at higher irradiation doses in the case of Al5083 alloy. The microindendation results showed that unirradiated Al5083 alloy has higher hardness value compared to that of unirradiated pure Al. The hardness increased marginally with irradiation dose in the case of Al5083, whereas for pure Al, there was no significant change with dose.

    The Instituto de Investigaciones Electricas has developed and implemented control systems in power stations with turbo gas unit (TGU) and of combined cycle power plants in which it has been detected several necessities and opportunities of technological development. One of most important is the improvement of the strategies of velocity control, power and temperature of the TGU, in order to obtain a safer and profitable operation. Since these units demand a strict and greater number of control requirements, because they are characterized by operating at temperatures, pressures and velocities higher than those of another type of units. An alternative to improve the control strategies of the TGU is the use of other control structures and the use of control techniques with diffuse logic, which can surpass the disadvantages of the conventional control. Due to the former, the reliability requirements of the TGU to get on line without fault, when required, have remarkably increased. The frequent accomplishment of starts, synchronization, load takings and shut-downs in a successful way and in automatic form, strongly depend on the capacities of the control system. During the starting, the main task of the control system consists of accelerating to the turbo-generator from the turn-shaft velocity to the nominal velocity according to a predefined acceleration pattern. The velocity control generates the control actions to accelerate the turbo-generator in a safe way that avoids the occurrence of instabilities of the working fluid, vibration discharges and resonances, high temperatures and combustion instabilities, and in addition, in the minimum of time, with fuel saving and preserving the useful life of the turbo-generator.

  2. 26Al in the interstellar medium

    International Nuclear Information System (INIS)

    Clayton, D.D.; Leising, M.D.

    1987-01-01

    Several different lines of physical reasoning have converged on the importance of the radioactive nucleus 26 Al. The sciences of meteoritics, nucleosynthesis, gamma-ray astronomy, galactic chemical evolution, solar system formation, and interstellar chemistry all place this nucleus in a central position with possible profound implications. Perhaps more importantly the study of this radioactivity can unite these diverse fields in a complicated framework which will benefit all of them. This review traces the evolution of ideas concerning 26 Al in the context of these disciplines. 26 Al was first discussed for the possibility that its decay energy could melt meteorite parent bodies, and its daughter, 26 Mg, was later found in meteorites with enhanced abundance. It was also among the first radioactivities expected to be synthesized in interestingly large quantities in nulceosynthetic events. The first definitive detection of gamma-rays from an interstellar radioactivity is that of 1.809 MeV gamma-rays from 26 Al. This discovery has many implications, some of which are outlined here. The whole problem of isotopic anomalies in meteorites is greatly influenced by the specific issues surrounding excess 26 Mg, whether it represents in situ decay of 26 Al or memory of conditions of the ISM. The relationships among these ideas and their implications are examined. (orig.)

Su importancia no solo radica en lo que significa en la morbilidad y la mortalidad infantil, sino que estos niños tienen habitualmente múltiples problemas posteriores. El Programa para la Reducción del BPN señala que los niños nacidos con un peso inferior a los 2 500 g presentan riesgo de mortalidad 14 veces mayor durante el primer año de vida, en comparación con los niños que nacen con un peso normal a término. Dentro de los factores de riesgo del BPN se han encontrado con mayor frecuencia en estudios realizados por diferentes autores, los siguientes: el embarazo en la adolescencia, la desnutrición en la madre, el hábito de fumar, la hipertensión arterial durante el embarazo, la sepsis cervicovaginal, la anemia y los embarazos gemelares, entre otros.

  10. Electrical switching in Sb doped Al23Te77 glasses

    Pumlianmunga; Ramesh, K.

    2017-08-01

    Bulk glasses (Al23Te77)Sbx (0≤ x≤10) prepared by melt quenching method show a change in switching type from threshold to memory for x≥5. An increase in threshold current (Ith) and a concomitant decrease in threshold voltage (Vth) and resisitivity(ρ) have been observed with the increase of Sb content. Raman spectra of the switched region in memory switching compositions show a red shift with respect to the as prepared glasses whereas in threshold switching compositions no such shift is observed. The magic angle spinning nuclear magnetic resonance (MAS NMR) of 27Al atom shows three different environments for Al ([4]Al, [5]Al and [6]Al). The samples annealed at their respective crystallization temperatures show rapid increase in [4]Al sites by annihilating [5]Al sites. The melts of threshold switching glasses (x≤2.5) quenched in water at room temperature (27 °C) show amorphous structure whereas, the melt of memory switching glasses (x>2.5) solidify into crystalline structure. The higher coordination of Al increases the cross-linking and rigidity. The addition of Sb increases the glass transition(Tg) and decreases the crystallization temperature(Tc). The decrease in the interval between the Tg and Tc eases the transition between the amorphous and crystalline states and improves the memory properties. The temperature rise at the time of switching can be as high as its melting temperature and the material in between the electrodes may melt to form a filament. The filament may consists of temporary (high resistive amorphous) and permanent (high conducting crystalline) units. The ratio between the temporary and the permanent units may decide the switching type. The filament is dominated by the permanent units in memory switching compositions and by the temporary units in threshold switching compositions. The present study suggests that both the threshold and memory switching can be understood by the thermal model and filament formation.

    2018-06-01

    A method named 'matrix exchange' to synthesize ZrAl3 and AlN reinforced Mg-Al composite was developed in this paper. By inserting Al-10ZrN master alloy into Mg matrix and reheating the cooled ingot to 550 °C, Al and Mg atoms diffuse to the opposite side. As a result, liquid melt occurs once the interface areas reach to proper compositions. Then dissolved Al atoms react with ZrN, leading to the in-situ formation of ZrAl3 and AlN particles, while the Al matrix is finally replaced by Mg. This study provides a new insight for preparing Mg composites.

    2017-09-12

    The study empirically investigated the idea that Quranic verses (Surah Al-Rehman) can help manage depression. Abdullah Ibn Mas'ud (radiAllahu anhu) reported that the Prophet (salAllahu alayhi wasalam) said, "Everything has an adornment, and the adornment of the Qur'an is Surah Al-Rehman." Surah Al-Rehman is the most rhythmic surah of the Quran, so it was used for our experimental study. The idea of the study was drawn from the premise that music therapy helps reduce depression. The objective of the present study was to investigate the efficacy of Surah Al-Rehman for managing depression in Muslim women admitted for treatment of major depressive disorder in a psychiatry ward of a government hospital. It was hypothesized that women diagnosed with severe depression in the treatment group will have reduced level of depression as compared to control group at post-assessment level. It was further hypothesized that the amount of decrease in depression in treatment group at the post-assessment level will be greater as compared to the control group. A purposive sample of 12 female patients diagnosed with depression was randomly assigned to the treatment group (n = 6) and control group (n = 6). Assessment was done at pre- and post-level by using Beck Depression Inventory-II. Both groups did not significantly differ on pre-assessment depression scores. Twelve structured group sessions of 22 min, two times a day, were conducted for a period of 4 weeks with the groups. Treatment group was made to listen to Surah Al-Rehman recited by Qari Abdul Basit, and control group was exposed to music used for relaxation and treatment of depression. Wilcoxon signed ranks test was used to find the within-group differences between pre- and post-assessment scores. Both groups had decreased level of depression at post-assessment level, so it was important to assess if there was any difference in level of decrease. Mann-Whitney U test for comparison of groups on level of decrease at the

    Con toda consideración y respeto me permito agregar algunas anotaciones al escrito del Académico Alberto Cárdenas Escobar, aparecido en el No. 22 de Medicina, para destacar algunos aspectos de la personalidad del doctor Alberto Schweitzer galardonado con el Premio Nobel de la Paz.

    A los 30 años de edad tomó una decisión dramática: Estudiar Medicina para trabajaren el África Ecuatorial. Cuando terminó sus investigaciones sobre enfermedades tropicales y sus prácticas hospitaLarias, partió para el Gabon al pequeño pueblo de Lambarené. La tarea era desconsoladora; La atención médica había que prestarla al aire libre; iba con su esposa, como enfermera y amanuense, y no se encontraba ni un intérprete, ni un ayudante. Cuando le llegaron la medicina y el equipaje hubo que acomodarlos en un viejo gallinero abandonado; el calor era insoportable y le venían enfermos de varias millas a la redonda, a pie o en Canoas.

    Las enfermedades más difundidas eran Malaria, Disentería, estreptococias y la más mortífera, la Tripanosomiasis Gambiense, para la que empezaban a llegar medicinas nuevas eficaces y las medidas preventivas como el suministro de agua potable y enmallado de ventanas impedían muchas contaminaciones.

    Pero la que causaba mayores dificultades y trabajo era la Mycobacteriasis Anestesiante, incurable, de difícil diagnóstico, afectando a varios miembros de la misma familia, de aspecto horripilante, con complicaciones neuríticas muy dolorosas, frecuente ceguera, e invalideces y procesos erisepelatososacrotéricos, que exigían acompañante para el cambio y lavado de vendas y suministro de alimentos.

    Multiple mechanisms could lead to up-regulation of dry-season photosynthesis in Amazon forests, including canopy phenology and illumination geometry. We specifically tested two mechanisms for phenology-driven changes in Amazon forests during dry-season months, and the combined evidence from passive optical and lidar satellite data was incompatible with large net changes in canopy leaf area or leaf reflectance suggested by previous studies. We therefore hypothesized that seasonal changes in the fraction of sunlit and shaded canopies, one aspect of bidirectional reflectance effects in Moderate Resolution Imaging Spectroradiometer (MODIS) data, could alter light availability for dry-season photosynthesis and the photosynthetic capacity of Amazon forests without large net changes in canopy composition. Subsequent work supports the hypothesis that seasonal changes in illumination geometry and diffuse light regulate light saturation in Amazon forests. These studies clarify the physical mechanisms that govern light availability in Amazon forests from seasonal variability in direct and diffuse illumination. Previously, in the debate over light limitation of Amazon forest productivity, seasonal changes in the distribution of light within complex Amazon forest canopies were confounded with dry-season increases in total incoming photosynthetically active radiation. In the accompanying Comment, Saleska et al. do not fully account for this confounding effect of forest structure on photosynthetic capacity.

    At Lawrence Berkeley Laboratory's (LBL) Advanced Light Source (ALS), three 4.6 m long undulators have been completed, tested and installed. A fourth is under construction. The completed undulators include two 5.0 cm period length, 89 period devices (U5.0s) which achieve a 0.85 T effective field at a 14 mm minimum gap and a 8.0 cm period length, 55 period device (U8.0) that reaches a 1.2 T effective field at a 14 mm minimum gap. The undulator under construction is a 10.0 cm period length, 43 period device (U10.0) that is designed to achieve 0.98 T at a 23 mm gap. Undulator magnetic gap variation (rms) is within 25 microns over the periodic structure length. Reproducibility of the adjustable magnetic gap has been measured to be within +/- 5 microns. Gap adjusting range is from 14 mm to 210 mm, which can be scanned in one minute. The 5.1 m long vacuum chambers are flat in the vertical direction to within 0.74 mm and straight in the horizontal direction to within 0.08 mm over the 4.6 m magnetic structure sections. Vacuum chamber base pressures after UHV beam conditioning are. in the mid 10 -11 Torr range and storage ring operating pressures with full current are in the low 10 -10 Torr range. Measurements show that the uncorrelated magnetic field errors are 0.23%, and 0.20% for the two U5.Os and the U8.0 respectively and that the field integrals are small over the 1 cm by 6 cm beam aperture. Device description, fabrication, and measurements are presented

    The α-NiPt(Al) phase and its associated equilibria in the Ni-Al-Pt system at 1150 deg C were investigated by analyzing equilibrated bulk alloys and the interdiffusion zones of diffusion couples. Phase constitutions, tie-lines and microstructures were determined using a combination of techniques, including high-energy synchrotron X-ray diffraction, scanning electron microscopy and electron probe microanalysis. A large Pt solubility limit was found to exist in the β-NiAl, ∼42 at.%, and in γ'-Ni 3 Al, ∼32 at.%. The α-NiPt(Al) phase was found to have wide Pt solubility range of about 33-60 at.% and to skew along an almost constant Pt/Al ratio of 1.5. The α-NiPt(Al) has an ordered face-centered tetragonal L1 0 crystal structure, with the Al and Pt atoms found to be preferentially located in the corners and prismatic faces, respectively. The temperature dependence of the lattice parameters and unit cell volume of the α phase were also determined

    The temperature dependence of the laboratory frame spin-lattice relaxation time of 27 Al nuclei is measured in 5N Al and in dilute Al-Ti, Al-Cr, Al-Mn, and Al-Cu alloys at 5.7 and 9.7 MHz resonance frequencies. The relaxation in pure aluminium is found to be purely due to the conduction electrons. An excess T 1 -relaxation contribution is detected in all Al-3d alloys investigated above 670 K. The excess relaxation rate is proportional to the impurity content and the temperature dependence of the excess contribution is of Arrhenius-type with an activation energy of (1.3 +- 0.3) eV for all of the investigated alloys. The relaxation contribution is found to be quadrupolar in origin and is caused by the relative diffusional jumps of solute atoms and Al atoms relatively far from the impurity. (author)

Parallel to the growing demands with respect to the automation of these units, the importance of PCS equipment has increased and with this the necessity for its qualification. Experience to date shows that the manufacturer's awareness of these requirements can be heightened still further. This paper describes approaches for improving the present situation and should be interpreted not as criticism but as providing an opportunity to increase the knowledge base and work together to define solutions which satisfy the guidelines. (orig.) [German] Der Einsatz von Package Units in Pharma-Anlagen erfaehrt zunehmende Verbreitung. Wenn sie an der Herstellung von Arzneimitteln beteiligt sind und auf die Qualitaet des Endprodukts Einfluss nehmen, unterliegen sie der Validierungspflicht, die der Anwender zu gewaehrleisten hat. Entsprechend den wachsenden Anforderungen an die Automatisierung dieser Einheiten ist auch der Stellenwert der PLT-Ausruestung angestiegen und mit ihm die Notwendigkeit von deren Qualifizierung. Die bisherige Praxis zeigt, dass die Sensbilitaet der Hersteller diesen Anforderungen gegenueber noch besser entwickelt werden kann. Der Beitrag zeigt Wege auf, um die derzeitige Situation zu verbessern und sollte nicht als Kritik sondern als Chance aufgefasst werden, den Wissensstand auszugleichen und gemeinsam zu richtliniengerechten Loesungen zu kommen.

    The objective of this project is to investigate the role of different types of layer interfaces on the formation of high density stacking fault (SF) in Al in Al/fcc multilayers, and understand the corresponding deformation mechanisms of the films. Stacking faults or twins can be intentionally introduced (via growth) into certain fcc metals with low stacking fault energy (such as Cu, Ag and 330 stainless steels) to achieve high strength, high ductility, superior thermal stability and good electrical conductivity. However it is still a major challenge to synthesize these types of defects into metals with high stacking fault energy, such as Al. Although deformation twins have been observed in some nanocrystalline Al powders by low temperature, high strain rate cryomilling or in Al at the edge of crack tip or indentation (with the assistance of high stress intensity factor), these deformation techniques typically introduce twins sporadically and the control of deformation twin density in Al is still not feasible. This project is designed to test the following hypotheses: (1) Certain type of layer interfaces may assist the formation of SF in Al, (2) Al with high density SF may have deformation mechanisms drastically different from those of coarse-grained Al and nanotwinned Cu. To test these hypotheses, we have performed the following tasks: (i) Investigate the influence of layer interfaces, stresses and deposition parameters on the formation and density of SF in Al. (ii) Understand the role of SF on the deformation behavior of Al. In situ nanoindentation experiments will be performed to probe deformation mechanisms in Al. The major findings related to the formation mechanism of twins and mechanical behavior of nanotwinned metals include the followings: 1) Our studies show that nanotwins can be introduced into metals with high stacking fault energy, in drastic contrast to the general anticipation. 2) We show two strategies that can effectively introduce growth twins in

    Full Text Available RESUMEN: La dependencia o adicción a sustancias de uso profesional es un problema que puede afectar gravemente a médicos de diferentes especialidades. En la anestesiología hay mayor riesgo de dependencia a opioides e hipnóticos que en otras especialidades y puede llegar a afectar al 1% de los médicos anestesiólogos.La fisiopatología del trastorno por uso de sustancias tiene hechos comunes para diferentes drogas. Interactúan la vulnerabilidad genética y factores psicosociales como predisponentes y los efectos psicobiológicos de la sustancia como factor gatillante. En el caso de los anestesiólogos, la sustancia se encuentra en el lugar de trabajo y por lo tanto, el individuo está constantemente expuesto.Una disfunción previa del sistema de recompensa en el circuito mesocorticolímbico o causada por la exposición a la sustancia adictiva es la piedra central de la neurobiología de las adicciones. Los opioides, anfetaminas, canabinoides, alcohol y nicotina, son algunas de las sustancias exógenas que activan el circuito y causan inicialmente un efecto hedónico que reforzará la conducta por repetir la experiencia. Con el tiempo la interacción con la droga será para evitar los síntomas de abstinencia.Dada la exposición laboral de los anestesiólogos, es necesario prevenir, detectar y tratar precozmente a quienes están abusando de sustancias durante su ejercicio profesional.Por las características de estos fármacos, aspectos psicológicos especiales de los médicos y el contexto laboral se hace necesario un tratamiento especializado y en anestesiólogos la reinserción laboral debe ser un proceso controlado, gradual y con un seguimiento prolongado.

This prospective study, carried out in an intensive care unit over the course of 14 days, describes the cleaning/disinfection conditions of four surfaces near patients. In total, 100 assessments of the surfaces were carried out after they were cleaned. Three methods were used to evaluate cleanliness: a visual inspection, an adenosine triphosphate (ATP bioluminescence assay and testing for the presence of Staphylococcus aureus and meticillin-resistant Staphylococcus aureus/MRSA. Respectively, 20%, 80% and 16% of the assessments by the visual method, ATP and the presence of Staphylococcus aureus/MRSA failed.

    Full Text Available This study aimed to identify and analyze aspects regarding the preparation for the worker-user relationship in a primary health care unit in a city in the state of São Paulo-Brazil, from the perspective of welcoming. The health work process is the theoretical basis of the study; participant observation and semi-structured interviews were used as data collection techniques, and thematic analysis in the analysis stage. For the welcoming to be processed, there is a "moment" of preparation for the worker, the physical environment and the relationships present at work so that users are welcomed, in which the users' needs are sometimes disregarded. Despite the difficulties in terms of resource availability, especially in the public sector, when preparing the service/user and worker/user relationships, one should consider the aspects associated to a more human, welcoming relationship, since it is during live work, in this intersection, that care quality is established.Se tuvo por objetivo identificar y analizar aspectos pertinentes a la preparación para la relación trabajador/usuario en una unidad de salud de la red de atención básica de un municipio del Estado de San Pablo, Brasil, teniendo como perspectiva el acogimiento.

    Experimental data on compressibility of aluminous silicate perovskite show widely disparate results. Several studies show that Al causes a dramatic increase in compressibility1-3, while another study indicates a mild decrease in compressibility4. Here we report new results for the effect of Al on the room-temperature compressibility of perovskite using in situ X-ray diffraction in the diamond anvil cell from 30 to 100 GPa. We studied compressibility of perovskite in the system MgSiO3-Al2O3 in compositions with 0 to 25 mol% Al. Perovskite was synthesized from starting glasses using laser-heating in the DAC, with KBr as a pressure medium. Diffraction patterns were obtained using monochromatic radiation and an imaging plate detector at beamline BL10XU, SPring8, Japan. Addition of Al into the perovskite structure causes systematic increases in orthorhombic distortion and unit cell volume at ambient conditions (V0). Compression of the perovskite unit cell is anisotropic, with the a axis about 25% and 3% more compressive than the b and c axes, respectively. The magnitude of orthorhombic distortion increases with pressure, but aluminous perovskite remains stable to at least 100 GPa. Our results show that Al causes only a mild increase in compressibility, with the bulk modulus (K0) decreasing at a rate of 0.7 GPa/0.01 XAl. This increase in compressibility is consistent with recent ab initio calculations if Al mixes into both the 6- and 8-coordinated sites by coupled substitution5, where 2 Al3+ = Mg2+ + Si4+. Our results together with those of [4] indicate that this substitution mechanism predominates throughout the lower mantle. Previous mineralogic models indicating the upper and lower mantle are compositionally similar in terms of major elements remain effectively unchanged because solution of 5 mol% Al into perovskite has a minor effect on density. 1.

    Full Text Available The redox reaction between Al and metallic oxide has its advantage compared with intermetallic reaction and Al/NiO nanomutlilayers are a promising candidate for enhancing the performance of energetic igniter. Al/NiO nanomutlilayers with different modulation periods are prepared on alumina substrate by direct current (DC magnetron sputtering. The thicknesses of each period are 250 nm, 500 nm, 750 nm, 1000 nm, and 1500 nm, respectively, and the total thickness is 3 μm. The X-ray diffraction (XRD and scanning electron microscope (SEM results of the as-deposited Al/NiO nanomutlilayers show that the NiO films are amorphous and the layered structures are clearly distinguished. The X-ray photoelectron spectroscopy (XPS demonstrates that the thickness of Al2O3 increases on the side of Al monolayer after annealing at 450°C. The thermal diffusion time becomes greater significantly as the amount of thermal boundary conductance across the interfaces increases with relatively smaller modulation period. Differential scanning calorimeter (DSC curve suggests that the energy release per unit mass is below the theoretical heat of the reaction due to the nonstoichiometric ratio between Al and NiO and the presence of impurities.

    2010-01-01

    A new ternary Al 2 CuIr phase was revealed in the Al-Cu-Ir system. It is formed below 1063 o C from the β-phase (CsCl-type structure) extending at elevated temperatures from AlIr. The crystal structure of the Al 2 CuIr phase was determined using a combination of precession electron diffraction and X-ray powder diffraction techniques. The phase has an orthorhombic C-centered unit cell with lattice parameters a = 8.1196(7) A, b = 5.0646(2) A and c = 5.18513(3) A; its crystal symmetry can be described by the Cmme (no. 67) space group (Pearson symbol oC16). The unit cell of the new phase contains 8 Al, 4 Cu and 4 Ir atoms and exhibits a new structure type. The reliability factors characterizing the Rietveld refinement procedure are: R p = 4.45%, R wp = 6.45%, R B = 3.69% and R f = 2.41%.

    Superconductor radiation detectors have the possibility of 20-30 times better energy resolution than that of a high resolution Si detector. We fabricated Nb/Al-AlOx/Al/Nb superconducting tunnel junctions with low leakage current. X rays were detected with large area junctions of 178x178 μm 2 . High energy resolution of 160 eV for 5.9 keV was obtained. We also fabricated series connected junctions which covers a rather large area of 4x4 mm 2 . α particles injected into the rear substrate were detected using nonthermal phonons induced by the radiations in the substrate.

  8. Hanford Site Waste Managements Units reports

    International Nuclear Information System (INIS)

    1992-01-01

    The Hanford Site Waste Management Units Report (HSWMUR) was originated to provide information responsive to Section 3004(u) of the Hazardous and Solid Waste Amendments (HSWA) of the 1984 United States Code (USC 1984). This report provides a comprehensive inventory of all types of waste management units at the Hanford Site, including a description of the units and the waste they contain. Waste management units in this report include: (1) Resource Conservation and Recovery Act of 1976 (RCRA) disposal units, (2) Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) disposal units, (3) unplanned releases, (4) inactive contaminated structures, (5) RCRA treatment, storage, and disposal (TSD) units, and (6) other storage areas. Because of the comprehensive nature of this report, the listing of sites is more extensive than required by Section 3004(u) of HSWA. The information in this report is extracted from the Waste Information Data System (WIDS). The WIDS provides additional information concerning the waste management units contained in this report and is maintained current with changes to these units. This report is updated annually if determined necessary per the Hanford Federal Facility Agreement and Consent Order Order (commonly referred to as the Tri-Party Agreement, Ecology et al. 1990). This report identifies 1,414 waste management units. Of these, 1,015 units are identified as solid waste management units (SWMU), and 342 are RCRA treatment, storage, and disposal units. The remaining 399 are comprised mainly of one-time spills to the environment, sanitary waste disposal facilities (i.e., septic tanks), and surplus facilities awaiting decontamination and decommissioning

    This discussion of the United Arab Emirates focuses on the following: the people; geography; history; government; political conditions; defense; the economy; foreign relations; and relations between the US and the United Arab Emirates. In 1983 the population was estimated at 1,194,000. In 1984 the annual growth rate was negative. Life expectancy is about 60 years. Fewer than 20% of the population are UAE citizens. Indigenous Emiris are Arab; the rest of the population includes significant numbers of other Arabs -- Palestinians, Egyptians, Jordanians, Yemenis, Omanis, as well as many Iranians, Pakistanis, Indians, and West Europeans, especially in Dubai. The UAE is in the eastern Arabian Peninsula, bounded on the north by the Persian Gulf. European and Arab pirates roamed the Trucial Coast area from the 17th century into the 19th century. Early British expeditions against the pirates led to further campaigns against their headquarters. Piracy continued intermittently until 1835, when the shaikhs agreed not to engage in hostilities at sea. Primarily in reaction to the ambitions of other European countries, the UK and the Trucial States established closer bonds in an 1892 treaty. In 1968 the British government announced its decision, reaffirmed in March 1971, to end the treaty relationship with the gulf shaikhdoms. When the British protective treaty with the Trucial Shaikhdoms ended on December 1, they became fully independent. On December 2, 1971, 6 of them entered into a union called the United Arab Emirates. The 7th, Ras al-Khaimah, joined in early 1972. Administratively, the UAE is a loose federation of 7 emirates, each with its own ruler. The pace at which local government in each emirate is evolving, from traditional to modern, is set primarily by the ruler. Under the provisional constitution of 1971, each emirate reserves considerable powers, including control over mineral rights, taxation, and police powers. In this milieu, the growth of federal powers has

    Amyotrophic lateral sclerosis (ALS) afflicts 2 of every 100,000 people in the United States each year. A well-known example of ALS today is Stephen Hawking. He is a theoretical physicist, the author of A Brief History of Time, and is virtually immobilized by ALS. Diseases that cause progressive paralysis because of motor neuron degeneration in the central nervous system are termed motor neuron disorders (MND). Amyotrophic lateral sclerosis is a common form of MND. Pain-free, progressive muscular weakness is the most common clinical symptom. There is chronic weakness with atrophy of the affected muscles by the time the disease is diagnosed. Atrophy eventually results in wheelchair confinement and then only bed without the ability to speak or swallow. Death often occurs as a result of respiratory problems. Unlike other neurodegenerative diseases, in ALS the patient`s bladder and bowel control, eye movement, and mental faculties are preserved. The question today is whether or not certain trace elements are involved in the etiology or pathogenesis of ALS. A collaborative study was undertaken by the University of Kentucky and Oak Ridge National Laboratory (ORNL) using neutron activation analysis (NAA) to study trace element concentrations in ALS patients fingernails to determine if there existed statistically significant imbalances.

    Using of Al and B2O3 powders as starting materials, and Mg-Al alloy as additives, AlB2-Al2O3 composite powders with AlB2 nanowire structures were successfully fabricated via combustion synthesis method in Ar atmosphere at a pressure of 1.5 MPa. The effect of different amount of Mg-Al alloy on the phase compositions and morphology of the combustion products was investigated. The results revealed that AlB2 and Al2O3 increased, whereas Al decreased with the content of Mg-Al alloy increasing. The impurities MgAl2O4 and AlB12 would exist in the sample with adding of 18 wt% Mg-Al alloy. Interestingly, FESEM/TEM/EDS results showed that AlB2 nanowires were observed in the products when the content of Mg-Al alloy is 6 wt% and 12 wt%. The more AlB2 nanowires can be found as the content of Mg-Al alloy increased. And the yield of AlB2 nanowires with the diameter of about 200 nanometers (nm) and the length up to several tens of micrometers (μm) in the combustion product is highest when the content of Mg-Al alloy is 12 wt%. The vapor, such as Mg-Al (g), B2O2 (g), AlO (g) and Al2O (g), produced during the process of combustion synthesis, reacted with each other to yield AlB2 nanowires by vapor-solid (VS) mechanism and the corresponding model was also proposed.

Thus, developing Islamic education usually begins with a study of a figure and his educational thought. And one of the most influential figures whose thought which has Sufi religious pattern has dominated educational thinking atmosphere over the centuries since his death. The purpose of education according to al-Ghazali was to get closer to Allah. He came with a view that the most noble job is to educate: to become a teacher. Al-Ghazali advised that his students, in the learning process, aim to become scientists who could disseminate their knowledge for the sake of humanity values.

    The advent of high-performance computer systems has brought to maturity programming concepts like vectorization, multiprocessing, and multitasking. While there are many schools of thought as to the most significant factor in obtaining order-of-magnitude increases in performance, such speedup can only be achieved by integrating the computer system and application code. Vectorization leads to faster manipulation of arrays by overlapping instruction CPU cycles. Discrete ordinates codes, which require the solving of large matrices, have proved to be major benefactors of vectorization. Monte Carlo transport, on the other hand, typically contains numerous logic statements and requires extensive redevelopment to benefit from vectorization. Multiprocessing and multitasking provide additional CPU cycles via multiple processors. Such systems are generally designed with either common memory access (multitasking) or distributed memory access. In both cases, theoretical speedup, as a function of the number of processors P and the fraction f of task time that multiprocesses, can be formulated using Amdahl's law: S(f, P) =1/(1-f+f/P). However, for most applications, this theoretical limit cannot be achieved because of additional terms (e.g., multitasking overhead, memory overlap, etc.) that are not included in Amdahl's law. Monte Carlo transport is a natural candidate for multiprocessing because the particle tracks are generally independent, and the precision of the result increases as the square Foot of the number of particles tracked

The coatings and NdFeB substrate combine well, and moreover, there is occurrence of metallurgy bonding in the interface layer. Both Al and AlN/Al coatings have a good protective ability to NdFeB. Especially, the corrosion resistance of AlN/Al coated NdFeB is improved largely. AlN/Al and Al protective coatings not only do not deteriorate the magnetic properties of NdFeB, but contribute to their slight increase.

    Magnetoresistance and rectification are two fundamental physical properties of heterojunctions and respectively have wide applications in spintronics devices. Being different from the well known various magnetoresistance effects, here we report a brand new large magnetoresistance that can be regarded as rectification magnetoresistance: the application of a pure small sinusoidal alternating-current to the nonmagnetic Al/Ge Schottky heterojunctions can generate a significant direct-current voltage, and this rectification voltage strongly varies with the external magnetic field. We find that the rectification magnetoresistance in Al/Ge Schottky heterojunctions is as large as 250% at room temperature, which is greatly enhanced as compared with the conventional magnetoresistance of 70%. The findings of rectification magnetoresistance open the way to the new nonmagnetic Ge-based spintronics devices of large rectification magnetoresistance at ambient temperature under the alternating-current due to the simultaneous implementation of the rectification and magnetoresistance in the same devices.

    Experimental data show that aluminium doped RCo 5 systems crystallize in CaCu 5 structure for most of the rare-earth elements (R). Al impurities randomly occupy one of the two possible positions (2c and 3g) and there is a critical concentration of Al, x c = 2.0, for RCo 5-x Al x when the Co sublattice becomes nonmagnetic. The ab initio self-consistent calculations show strong dependence of magnetic properties of RCo 5-x Al x concentration of Al; and position of the impurities in the unit cell, furthermore to fulfill experimental observation of existence of critical concentration, x c = 2.0, the Al impurities should prefer 3g positions otherwise the magnetic moments on Co atoms do not vanish.

    Congenital scoliosis (CS) is a common vertebral malformation with incidence of up to 1 of 1000 births worldwide. Recently, TBX6 has been reported as the first disease gene for CS: about 10% of CS patients are compound heterozygotes of rare null mutations and a common haplotype composed by 3 SNPs in TBX6. Lefebvre et al in this journal reported that 2 patients with spondylocostal dysostosis (SCD), a rare skeletal dysplasia affecting spine and ribs also have TBX6 mutations: 1 carried the microdeletion and a rare missense variant, and another 2 rare missense variants. We investigated the pathogenicity of the 3 missense variants in SCD by a luciferase assay. The results were negative for the proposal of Lefebvre et al. We consider these 2 SCD patients are more probably compound heterozygotes of null mutations and a common risk haplotype just as CS patients with TBX6 mutations. © 2017 John Wiley & Sons A/S.

    1997-01-01

    The oxide phases formed on an Al-deposited Fe-Cr-Al alloy foil and an Fe-Cr-Al alloy foil of the same levels of Al and (La+Ce) contents, and their oxidation kinetics have been studied in air at 1173 and 1373 K using TGA, XRD and SEM. Al deposition promotes the growth of metastable aluminas (θ-Al 2 O 3 , γ-Al 2 O 3 ). Scales consisting of θ-Al 2 O 3 and a small amount of α-Al 2 O 3 develop on the Al-deposited foil at 1173 K and exhibit the whisker-type morphology. In the early stage of oxidation at 1373 K, thick scales consisting of θ-Al 2 O 3 and α-Al 2 O 3 grow rapidly on the Al-deposited foil. The transformation from θ-Al 2 O 3 to α-Al 2 O 3 is very fast, and the scales result in only α-Al 2 O 3 . In contrast, α-Al 2 O 3 scales containing a minor amount of FeAl 2 O 4 develop on the alloy foil. The growth rate of α-Al 2 O 3 scales on the Al-deposited foil is smaller than that on the alloy foil and very close to that on NiAl at 1373 K. (orig.)

    Lisovski et al. [1] describe the widely recognized limitations of light-level geolocator data for identifying short-distance latitudinal movements, recommend that caution be used when interpreting such data, intimated that we did not use such caution and argued that environmental shading likely explained the Golden-winged Warbler (Vermivora chrysoptera) movements described in our 2015 report [2] . Lisovski et al. [1] conclude that the bird movements we reported could not be disentangled from estimation error in stationary animals caused by environmental shading. We argue that, to the contrary, these hypotheses can easily be disentangled because the premise that environmental shading caused synchronous and parallel error among geolocators is false. With their assertion that our location estimates could be biased by >3,500 km on a day with no observable local sources of shading, Lisovski et al. [1] have taken a position of incredulity toward all geolocator-based animal movement data published to date.

Jahrhundert beschreibt Pauline Puppel unter ausführlichem Bezug auf zeitgenössische Literatur und Archivalien sowohl die allgemeine Rechtslage im damaligen Reich als auch die Anwendungsfälle in Hessen, wo zwischen 1500 und 1700 insgesamt viermal eine Landgräfin als Vormünderin des Fürsten zur Regentin ihres Landes wurde. Dies steht exemplarisch für eine bereits in der Frühen Neuzeit mögliche und nicht einmal ganz seltene Form politischer Frauenherrschaft, die bisher oft nicht hinreichend gewürdigt wurde. Puppels Untersuchung ist in zwei Hauptteile gegliedert. Der erste Teil (Das juristische Regelwerk“, S. 34-143 behandelt die zeitgenössischen Rahmenbedingungen der durch Frauen ausgeübten Vormundschaft und Regentschaft. Der zweite Abschnitt („Die Landgräfinnen von Hessen als Regentinnen“, S. 144-307 befasst sich mit der Ausfüllung dieser Regeln durch konkrete Fallbeispiele in Gestalt von Leben und Regentschaft der regierenden Landgräfinnen von Hessen.

    Despite knowledge on the molecular basis of amyotrophic lateral sclerosis (ALS) having quickly progressed over the last few years, such discoveries have not yet translated into new therapeutics. With the advancement of stem cell technologies there is hope for stem cell therapeutics as novel treatments for ALS. We discuss in detail the therapeutic potential of different types of stem cells in preclinical and clinical works. Moreover, we address many open questions in clinical translation. SC therapy is a potentially promising new treatment for ALS and the need to better understand how to develop cell-based experimental treatments, and how to implement them in clinical trials, becomes more pressing. Mesenchymal stem cells and neural fetal stem cells have emerged as safe and potentially effective cell types, but there is a need to carry out appropriately designed experimental studies to verify their long-term safety and possibly efficacy. Moreover, the cost-benefit analysis of the results must take into account the quality of life of the patients as a major end point. It is our opinion that a multicenter international clinical program aime d at fine-tuning and coordinating transplantation procedures and protocols is mandatory.

    The Vienna Integrated Model of Art Perception (VIMAP; [5]) is the most comprehensive model of the art experience today. The model incorporates bottom-up and top-down cognitive processes and accounts for different outcomes of the art experience, such as aesthetic evaluations, emotions, and physiological and neurological responses to art. In their presentation of the model, Pelowski et al. also present hypotheses that are amenable to empirical testing. These features make the VIMAP an ambitious model that attempts to explain how meaningful, complex, and profound aspects of the art experience come about, which is a significant extension of previous models of the art experience (e.g., [1-3,10]), and which gives the VIMAP good explanatory power.

    Total reaction cross sections for the transfer reactions 27 Al( 18 O, 16 O) 29 Al, 27 Al( 18 O, 17 O) 28 Al and 27 Al( 13 C, 12 C) 28 Al are reported for center-of-mass energies between 13 and 20 MeV for 18 O projectiles and between 11 and 17.5 MeV for 13 C projectiles. The reaction products, 29 Al, and 28 Al, beta decay to 29 Si and 28 Si, respectively, and the subsequent γ decays of 29 Si and 28 Si were measured. Due to the relatively long beta decay half lives, data were taken in a beam-off mode, resulting in very clean spectra. Total cross sections were calculated and compared with a theoretical model for barrier penetration proposed by C.Y. Wong. Differences between 18 O induced one and two-neutron total transfer reaction cross sections are discussed. (orig.) [de

    2009-01-01

    To improve the specific strength and stiffness of Al-based composites, AlN/Al nanoparticles were in-situ synthesized by arc plasma evaporation of Al in nitrogen atmosphere and consolidated by hot-pressing to fabricate AlN nanoparticle-reinforced nanocrystalline Al composites (0-39 vol.% AlN). Microstructure characterization shows that AlN nanoparticles homogeneously distribute in the matrix of Al nanocrystalline, which forms atomically bonded interfaces of AlN/Al. The hardness and the elastic modulus of the nanocomposite have been improved dramatically, up to 3.48 GPa and 142 GPa, respectively. Such improvement is believed to result from the grain refinement strengthening and the interface strengthening (load transfer) between the Al matrix and AlN nanoparticles

  15. A study of ion damage in Al, Al/Cu and Al/Ag

    International Nuclear Information System (INIS)

    Marikar, P.

    1979-06-01

    Specimens of pure aluminium, aluminium-copper and aluminium-silver have been irradiated with 20 keV helium ions and/or 100 keV aluminium ions and the nature of the damage assessed using transmission electron microscopy. Irradiation with 20 keV helium ions to a dose of 2.7 x 10 15 ions cm -2 results in the formation of interstitial loops and helium gas bubbles. The helium bubbles were detectable only after annealing at a high temperature following irradiation. When the helium preinjected aluminium specimens were irradiated with 100 keV Al + ions to a dose of 84 dpa at temperatures above 150 0 C, voids were observed to form. At a lower dose of 64 dpa, only a high density of dislocation loops was observed. Al-1 wt% Cu alloy containing partially coherent theta' precipitates resists void formation to a considerable extent, and Al-10 wt% Ag alloy containing coherent G.P. zones offers complete resistance to both dislocation loop nucleation and void formation. The experimental results are discussed in the light of the current theories of irradiation induced damage in metals. The importance of the dislocation-sink efficiency for point defects, the gaseous impurity and the alloying elements in determining void formation is highlighted. (author)

    Mössbauer spectroscopy, X-ray diffraction (XRD) measurements, and electron microprobe analysis (EMPA) have been performed on two meteorites named Al-Dalang and Al-Hawashat after identifying their falling sites in the Western region of Sudan. These two meteorites are ordinary chondrites with similar mineralogy. XRD and EMPA show that the two specimens consist of primary olivine, ortho-pyroxene and later crystallising clino-pyroxene as reaction rims against plagioclase. Fe-metal phases are dominated by kamacite (≈6 wt.% Ni) and minor amounts of tetrataenite (≈52 wt.% Ni). Troilite (FeS) and alabandite (MnS) are optically observed as sulphide phases. The Mössbauer measurements at 295 and 78 K are in agreement with the above characterizations, showing at least two paramagnetic doublets which are assigned to olivine and pyroxene and magnetic sextets assigned to kamacite (hyperfine field ≈33.5 T) and troilite FeS (hyperfine field ≈31 T).

    Curiously, amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), seemingly disparate neurodegenerative disorders, can be inherited together. Two groups (DeJesus-Hernandez et al. and Renton et al.) show that the long sought after ALS/FTD mutation on chromosomal region 9p is a hexanucleotide expansion in C90RF72. These studies, plus a study on X-linked ALS/FTD, provide molecular starting points for identifying pathways that link ALS and FTD pathogenesis. Copyright © 2011 Elsevier Inc. All rights reserved.

    The ALS Gun Electronics system has been designed to accommodate the gun with a custom made socket and a high speed electronics circuit which is capable of producing single and multiple electron bunches with time jitters measured at better than 50 PS. The system generates the gated RF signal at ground level before sending it up to the 120 KV-biased gun deck via a fiber optic cable. The current pulse width as a function of grid bias, using an Eimac 8847A planar triode simulating an electron gun, was measured to show the relationship between the two parameters

    Full Text Available The Qur’an is singularly distinctive in its style compared to any human composition. Human eloquence, with its remarkable history in the composition of poetry, has failed to compose even a single verse like that of the Qur'an. The Qur'anic composition is a living challenge for human beings to imitate its miraculous style. This inimitable aspect of the Qur'an, among other things, proves that it was revealed by Allah (SWT to Prophet Muhammad (SAAS. In addition, the miracle of its linguistic composition was a means to declare the faith based on monotheism and the introduction of a new order and a theo-centric guidance that was meant to unite humanity. Adopting the monotheistic faith gave rise to a new community, the Muslim ummah that was able to bridge the differences between human beings in culture, race, colour and geographical boundaries. Consequently, the unique style of the Qur’an deserves a careful study. The present study investigates the use of interrogative utterances in surah al-Baqarah and their contribution to the Qur'an's rhetorical style. Hopefully, the results of this study will be useful in later investigations of other parts of the Qur' an...

    The roll bonding technique is one of the most widely used methods to produce metal laminate sheets. Such sheets offer interesting research opportunities for both scientists and engineers. In this paper, we report on an experimental investigation of the 'thickness effect' during laminate rolling for the first time. Using a four-high multifunction rolling mill, Cu/Al/Cu laminate sheets were fabricated with a range of thicknesses (16, 40, 70 and 130 μm) of the Al layer. The thickness of the Cu sheets was a constant 300 μm. After rolling, TEM images show good bonding quality between the Cu and Al layers. However, there are many nanoscale pores in the Al layer. The fraction of nanoscale pores in the Al layer increases with a reduction in the Al layer thickness. The finite element method was used to simulate the Cu/Al/Cu rolling process. The simulation results reveal the effect of the Al layer thickness on the deformation characteristics of the Cu/Al/Cu laminate. Finally, we propose that the size effect of the Al layer thickness during Cu/Al/Cu laminate rolling may offer a method to fabricate 'nanoporous' Al sandwich laminate foils. Such foils can be used in electromagnetic shielding of electrical devices and noisy shielding of building.

    In the Laguna Verde power plant (CLV) worn out control bars have been replacing for control rods of advanced design. At the moment of the 109 rods of similar design to the original of the Unit 1 of the CLV, 14 of them have been substituted with two types of different advanced control rods. The same as the original rods the advanced rods use boron carbide as control element for neutrons, but additionally they use hafnium, to achieve a longer useful half life. The rods of similar design to the original are homogeneous axially on the other hand the advanced presenting several zones. In principle the advanced rods were designed to be neutronically compatible to the original rods. However the differences in the design and of constituents assumed to consider a different performance during the operation. Since the one numbers of advanced bars is growing with the number of cycles of the CLV reactor has requested to the National Institute of Nuclear Research (ININ) to evaluate in detailed form the performance of the control rods. Previously the calculations and analysis of cycle design that that were carried out assumed that control rods should be of similar design as the original. Using the HELIOS/CM-LENDS system, the effect of the inclusion of advanced rods was analyzed in the approximation of the criticality in cold (20 C) in the cycle 10 of the Unit 1. Four scenarios were poposed, where the type of the rod of substitution control is varied. The value of reactivity was calculated for the rods similar in design to the original and for the advanced one. By comparison of these values, it was found that the value of reactivity of the control rods of the advanced design was superior to the value for rods similar to the original ones by 7.6% for one of the advanced designs and of 13.6% for the other one.

    Full Text Available Do paid work activities displace volunteering? A potential explanation from role overload theoryRecent changes in Dutch society might lead to a shortage of volunteers. On the one hand, the demand for volunteers is increasing: in the social welfare domain because of governmental austerity policies and in other domains such as sports because of the higher supervision intensity of activities. On the other hand, the supply of volunteers is likely to decrease as more and more women and older workers are active in the labor market, which reduces the time that is available for volunteering. Role overload theory would suggest that the increasing labor participation rate of certain categories of workers goes along with a decline of participation in voluntary work. The secondary data analysis shows that various role loads (work, care for children living at home are associated with differences in participation in voluntary work. However, while a higher number of contractual work hours and hours spent on work-related training are negatively associated with volunteer work, care for children living at home is positively associated with volunteering. These results provide only limited support for role overload theory.Betaalde arbeid als verdringer van vrijwilligerswerk? Overbelasting als mogelijke verklaringDe afgelopen jaren hebben zich enkele maatschappelijke veranderingen voorgedaan, die wellicht tot schaarste op de Nederlandse vrijwilligersmarkt zouden kunnen leiden. Enerzijds neemt de vraag naar vrijwilligers toe doordat subsidieregelingen versoberen (bijvoorbeeld in zorg en welzijn en de begeleidingsintensiteit in bepaalde organisaties stijgt (bijvoorbeeld in sport. Anderzijds neemt het aanbod van vrijwilligers af doordat vrouwen en ouderen meer en langer op de arbeidsmarkt actief zijn, waardoor minder tijd beschikbaar is voor vrijwilligerswerk.

    The XRF analytical method was used to measure the weight % of the major oxides in regolith samples. The metal weight % of Mg, K and Al were calculated from their oxides and were normalised relative to immobile Al calculated from its oxide. The plot of Mg/Al and K/Al identified the regolith of the study area to consist of 137 transported clays, 4 ferruginous sediments or ferricrete, 2 lateritic duricrust and 4 saprolites. Surface regolith that had undergone secondary transformation and shows compositional overlaps were 4 transported clays with Fe-oxide impregnation may be referred to as nodular laterite and 5 ferruginous saprolites. The variable regolith materials features identified from the 154 samples enabled the characterisation and identification of the different sample materials because an overprint of bedrock geochemistry is reflected in the regolith. Plot of Mg/Al and K/Al highlighted the compositional variability of the regolith samples and refute the notion of the homogeneity of all the sampled materials in the area. The study thus recognized Mg/Al versus K/Al plots to be used in supporting field identification of regolith mapping units particularly in complex regolith terrains of savannah regions of Ghana and in similar areas where geochemical exploration surveys are being carried out under cover.

    The effects of aluminium (Al 3+ )-dopant on the precipitation of uniform lath-like α-FeOOH particles, the obtention and growth of α-(Fe,Al)OOH and α-(Fe,Al) 2 O 3 solid solutions, particle size and shape were investigated using X-ray powder diffraction, Moessbauer and Fourier transform infrared spectroscopies, field emission scanning electron microscopy and energy dispersive X-ray spectroscopy. Acicular α-FeOOH particles, precipitated in a highly alkaline medium with the addition of tetramethylammonium hydroxide (TMAH), were used as reference material. The influence of Al-dopant was investigated by adding varying amounts of Al 3+ ions to the initial FeCl 3 solution. In the presence of lower concentrations of aluminium ions (up to 11.11 mol%) α-(Fe,Al)OOH as a single phase was formed, whereas higher concentrations led to an additional obtention and growth of α-(Fe,Al) 2 O 3 . Al-for-Fe substitution in the α-FeOOH and α-Fe 2 O 3 structures was confirmed by a decrease in the unit-cell dimensions, a decrease in the hyperfine magnetic field and an increase in the wave number of the infrared absorption bands. The presence of lower concentrations of aluminium ions (up to 11.11 mol%) in the precipitation system did not affect the size and shape of the α-(Fe,Al)OOH particles, whereas higher concentrations influenced a decrease in the length and aspect ratio. In the presence of 42.86 mol% Al 3+ ions fairly uniform disc-shaped α-(Fe,Al) 2 O 3 were formed.

    The Al-rich part of the Al-Re phase diagram was reinvestigated by scanning and transmission electron microscopy, powder X-ray diffraction and differential thermal analysis. The earlier reported Al 12 Re, Al 6 Re, and Al 11 Re 4 phases were confirmed. Close to the Al 4 Re composition a high-temperature h-Al 4 Re and a low-temperature l-Al 4 Re phase were found to be formed at slightly different compositions. Both exhibited compositional ranges. A new phase was revealed close to the Al 3 Re composition. The Al 11 Re 4 phase is formed congruently at 1650 deg. C, Al 3 Re peritectically at 1610 deg. C, h-Al 4 Re peritectically at 1410 deg. C, l-Al 4 Re peritectically at ∼1000 deg. C, Al 6 Re peritectically at 813 deg. C and Al 12 Re peritectically at 746 deg. C. Finally, the Al 12 Re-(Al) eutectic is formed at 658 deg. C. The Al 3 Re and h-Al 4 Re are decomposed by eutectoid reactions at ∼946 and 833 deg., respectively. The structure of the h-Al 4 Re phase has not yet been clarified, but it is distinctly different from the Al 4 W phase suggested earlier. The structure of l-Al 4 Re was confirmed. The Al 3 Re phase was found to have a monoclinic structure with a = 0.5180(4) nm, b = 3.97641(9) nm, c = 0.4955(3) nm and β = 99.55(7) o

    Highlights: •2DEG and 2DHG coexist in the AlGaN/AlN/GaN/AlGaN DH-structure. •The sheet densities of 2DEG and 2DHG vary with buffer Al content and GaN thickness. •The conditions for the disappearance of 2DHG are discussed. •Increasing buffer Al content provides better electron confinement. •Dislocation scattering is reduced in the DH-structure. -- Abstract: This is a theoretical study of AlGaN/AlN/GaN/AlGaN double heterojunction (DH) structure with AlGaN as buffer layer. Our calculation shows that as the buffer Al content increases, though two-dimensional electron gas (2DEG) sheet density decreases, the channel back-barrier caused by polarization-induced electric field in GaN provides better electron confinement. And under certain conditions the DH-structure shows bipolar characteristics, with an additional two-dimensional hole gas (2DHG) formed at GaN/AlGaN interface. The influence of the buffer Al content and GaN channel thickness on the 2DEG and 2DHG sheet densities are investigated, and the conditions for the disappearance of 2DHG are discussed. Also, the mobility inhibited by dislocation scattering is enhanced in DH-structure due to the enhancement of screening effect of the 2DEG

    Full Text Available Beauty, according to Ibn Arabi, is pronounced to men in two ways: on one hand, by the elevation and power of the divine presence, named Majesty of Beauty, which we must respond through a spiritual state of privacy to accomplish balance during both contemplation and a correct apprehension; on the other hand, through proximity, aspect of Beauty, that should be received with fear for a proper response to God's expansion towards us, achieving in consequence, our gathering with Him. Those who love because of the divine love, contemplate the wisdom echoed in both: the universe as well as in themselves. Ibn Arabi also explained the application of these names to the reading of the Koran. The Prophet sustained the importance of spiritual embellishment achieved by a correct conduct and the contemplation of Beauty, this last one characterized by making all things likable and knowledgeable. Everything is inclined to be self loved, but this is only possible because of Reality's divinity; since God created the world to His image, it is considered as a mirror in which He contemplates and loves Himself.

    The compounds of the REPt 6 Al 3 series (RE = Ce-Nd, Sm, Gd, Tb) were obtained by reaction of the elements via arc-melting. They were characterized by powder and single-crystal X-ray diffraction (NdPt 6 Al 3 : wR = 0.0432, 759 F 2 values, 33 variables) as well as by magnetic susceptibility measurements. The isostructural compounds crystallize with a new structure type in the trigonal crystal system with space group R anti 3c, twelve formula units in the unit cell, and lattice parameters of a = 752-755 and c = 3882-3945 pm. The crystal structure can be described by different slabs stacked along [001]. One layer features Pt 3 triangles, centering the cavities of a flat honeycomb RE layer that are arranged in a..ABCA ' B ' C ' .. sequence. The other layer consists of condensed hexagonal [Pt 6 Al 6 ] prisms, centered by Pt atoms, separating the before mentioned slabs. Magnetic measurements revealed that all rare-earth atoms are in the trivalent oxidation state, however, due to the low lanthanoide content magnetic ordering phenomena were observed only at low temperatures [SmPt 6 Al 3 : T C = 5.0(1) K; GdPt 6 Al 3 : T C = 7.3(1) K; TbPt 6 Al 3 : T N = 3.6(1) K].

    The authors discuss the TiAl/Ti 3 Al interfacial misfit dislocations structures investigated by TEM in Ti-45Al alloy and Ti-45Al/TiB 2 composite. For TiAl with c/a = 1.02, only a single set of misfit dislocation arrays are crystallographically possible; these were observed in Ti-45Al alloy. However, the observation of three sets of misfit dislocation arrays in the Ti-45Al/TiB 2 composite suggests that the occupation of octahedral sites in the TiAl structure by excess boron was responsible for a decrease in the c/a ratio leading to an increased fcc character of the TiAl at the TiAl/Ti 3 Al interface

    [figure removed for brevity, see original site] Click on the image for Opportunity's 'Rub al Khali' Panorama (QTVR) This panoramic image, dubbed 'Rub al Khali,' was acquired by NASA's Mars Exploration Rover Opportunity on the plains of Meridiani during the period from the rover's 456th to 464th sols on Mars (May 6 to May 14, 2005). Opportunity was about 2 kilometers (1.2 miles) south of 'Endurance Crater' at a place known informally as 'Purgatory Dune.' The rover was stuck in the dune's deep fine sand for more than a month. 'Rub al Khali' (Arabic translation: 'the empty quarter') was chosen as the name for this panorama because it is the name of a similarly barren, desolate part of the Saudi Arabian desert on Earth. The view spans 360 degrees. It consists of images obtained in 97 individual pointings of the panoramic camera. The camera took images with five camera filters at each pointing. This 22,780-by-6,000-pixel mosaic is an approximately true-color rendering generated using the images acquired through filters admitting light wavelengths of 750, 530, and 480 nanometers. Lighting varied during the nine sols it took to acquire this panorama, resulting in some small image seams within the mosaic. These seams have been smoothed in sky parts of the mosaic to better simulate the vista that a person would see if able to view it all at the same time on Mars. Opportunity's tracks leading back to the north (center of the panorama) are a reminder of the rover's long trek from Endurance Crater. The deep ruts dug by Opportunity's wheels as it became stuck in the sand appear in the foreground. The crest and trough of the last ripple the rover crossed before getting stuck is visible in the center. These wind-formed sand features are only about 10 to 15 centimeters (4 to 6 inches) tall. The crest of the actual ripple where the rover got stuck can be seen just to the right of center. The tracks and a few other places on and near ripple crests can be seen in this color image to

    The coefficient of linear thermal expansion (α av ) of MgAl 2 O 4 (s) has been determined using a Netzsch 402 PC dilatometer with Al 2 O 3 (s) as the push-rod. The change in length per unit length was recorded as a function of temperature between room temperature to 1273 K at a heating rate of 8 K.min /1 , in argon flowing atmosphere. The average of three measurements was quoted as the α av for MgAl 2 O 4 (s). The linear thermal expansion was measured to an accuracy of ±3%. (author)

    2016-01-01

    Full Text Available Interest in spoken-language corpora has increased over the past two decades leading to the development of new corpora and the discovery of new facets of spoken language. These types of corpora represent the most comprehensive data source about the language of ordinary speakers. Such corpora are based on spontaneous, unscripted speech defined by a variety of styles, registers and dialects. The aim of this paper is to present the Croatian Adult Spoken Language Corpus (HrAL, its structure and its possible applications in different linguistic subfields. HrAL was built by sampling spontaneous conversations among 617 speakers from all Croatian counties, and it comprises more than 250,000 tokens and more than 100,000 types. Data were collected during three time slots: from 2010 to 2012, from 2014 to 2015 and during 2016. HrAL is today available within TalkBank, a large database of spoken-language corpora covering different languages (https://talkbank.org, in the Conversational Analyses corpora within the subsection titled Conversational Banks. Data were transcribed, coded and segmented using the transcription format Codes for Human Analysis of Transcripts (CHAT and the Computerised Language Analysis (CLAN suite of programmes within the TalkBank toolkit. Speech streams were segmented into communication units (C-units based on syntactic criteria. Most transcripts were linked to their source audios. The TalkBank is public free, i.e. all data stored in it can be shared by the wider community in accordance with the basic rules of the TalkBank. HrAL provides information about spoken grammar and lexicon, discourse skills, error production and productivity in general. It may be useful for sociolinguistic research and studies of synchronic language changes in Croatian.

  9. Crystal structure and stability of LiAlD4 with TiF3 additive

    2005-01-01

    LiAlD 4 samples with TiF 3 additives have been investigated by synchrotron X-ray diffraction, neutron diffraction and a Sieverts-type apparatus. Directly after ball milling there are no signs of any Ti-containing phases, and the unit-cell of LiAlD 4 and Al give no indication of any solid solutions. Hence it is concluded that the Ti is in an amorphous state directly after ball milling. Furthermore, no LiF was observed in the samples. Based on Sieverts-type measurements the plateau pressure at 80 deg C has been proved to be higher than 85 bar. Samples stored in a glove box are slowly desorbed, and after 6 months for a LiAlD 4 + TiF 3 sample, the reaction to LiD + Al is nearly finished

    En alguna ocasión se ha escuchado una palabra, que causa un sentimiento y a la vez un recuerdo, que lleva a evocar la adolescencia o la infancia, se recuerda quien la pronunciaba y en que ocasión la decía. Este es el poder que tiene una palabra y más aún si es dicha por el padre, puesto que este es la figura significativa que se lleva en la memoria. De aquí nace el interés de realizar un estudio, en donde se describe y analice la percepción y el sentimiento del adolescente, quien en esta etapa es vulnerable al cambio, ya que está buscando su propia identidad; que con el trato verbal paterno la encontrara sin ninguna dificultad o por el contrario nunca la encontrará.

    Full Text Available Compliance bedeutet nicht nur Einhaltung und Beachtung von Vorschriften, sondern betrifft auch Maßnahmen, die die Einhaltung der Rechtsnormen absichern sollen und läuft somit auf eine Übererfüllung von Verpflichtungen hinaus. Wenn es keinen klaren Maßstab für Kontroll- und Überwachungspflichten gibt, besteht die Gefahr, dass Strafverfolgungsbehörden die Compliance-Maßnahmen als Maßstab heranziehen und so eine Verschärfung der Pflichten erzeugen. Nach den Regeln des Verbandsverantwortlichkeitsgesetzes schließt im Übrigen das beste Compliance-System nicht zwingend die Verbandsverantwortlichkeit aus, steht aber unter Umständen einem Verfahren gegen den Verband entgegen.

    2017-01-02

    The microstructures, phase transformations, mechanical properties and shape memory effect of Ti-20Zr-10Nb-xAl (x=1, 2, 3, 4 at%) alloys were investigated. The X-ray diffraction results show that the alloys are composed of a single martensitic α″-phase and that the corresponding unit cell volume decreases with increasing Al content. The reverse martensitic transformation start temperature (A{sub s}) of the Ti-20Zr-10Nb-Al alloy is 534 K and decreases with increasing Al content. The addition of Al results in solid solution strengthening and grain refinement strengthening, thus improving the mechanical properties and the shape memory effect of the Ti-20Zr-10 Nb-xAl alloys. The Ti-20Zr-10Nb-3Al alloy shows the greatest shape memory strain (3.2%) and the largest tensile strain (17.6%) as well as a very high tensile strength (886 MPa).

  15. Orientation of Al3Ti platelets in Al-Al3Ti functionally graded material manufactured by centrifugal method

    Watanabe, Y.; Fukui, Y.

    1997-01-01

    Al-Al 3 Ti functionally graded materials (FGMs) were manufactured by the centrifugal method with a commercial ingot of Al-5 mass% Ti master alloy. The alloy was melted at a liquid/solid coexisting temperature, at which Al 3 Ti remains as a solid, and then it was cast into a thick-walled ring. It was found that the Al-Al 3 Ti functionally graded material can be successfully fabricated by the centrifugal method. It was also found that the volume fraction of the Al 3 Ti can be increased by repetition of the centrifugal method. Since the shape of Al 3 Ti particles in a commercial alloy ingot is that of a platelet, the Al 3 Ti particles are arranged with their platelet planes nearly perpendicular to the radial direction. The orientation effects become stronger when the G number becomes larger. Although the final centrifugal casting was conducted under a very large centrifugal force for the specimen cast three times, the orientation effects were weaker than those in the specimen cast one time. From these observations, it is concluded that the origin of orientation of Al 3 Ti platelets can be attributed to the angular velocity gradient of the melt along the radial direction produced by the difference in the viscosity.

    Bordallo, H N; Kolesnikov, A I; Kolomiets, A V; Kalceff, W; Nakotte, H; Eckert, J

    2003-01-01

    The optical vibrations of hydrogen in TbNiAlH 1.4 and UNiAlH 2.0 were investigated by means of inelastic neutron scattering. The experimental data were analysed, including multiphonon neutron scattering contributions, calculated in an isotropic harmonic approximation. At least two fundamental H optical peaks were observed in TbNiAlH 1.4 , and were assigned to the vibrational modes of hydrogen atoms occupying different interstitial sites in the metal sublattice. The high-energy part of the UNiAlH 2.0 spectra is characterized by strong anharmonicity, and a broad fundamental band. The latter can be accounted for by a large dispersion of phonon modes due to the strong H-H interactions, and/or different metal-hydrogen force constants, which may originate from different metal atoms surrounding the H atoms in the unit cell

    We aimed to study the anatomical distribution, severity and outcome of hospitalised interpersonal violence-related injured patients in Al-Ain, United Arab Emirates so as to give recommendations regarding the magnitude of this problem, its causes and priorities of prevention. Data were retrieved from Al-Ain Hospital Trauma Registry, which was prospectively collected over three years. There were 75 patients (males = 85.3%) having a mean age of 30 years. Eighty-one percent had blunt trauma. The estimated annual injury hospitalisation of interpersonal violence in Al-Ain city was 6.7 per 100,000 population. Females were significantly more injured by a family member (p = 0.02), at home (p = 0.005), and had more severe injuries (p = 0.003). There was a trend for children less than 18 years old to have more penetrating trauma (p = 0.06) and to be injured by a family member (p = 0.09). There was only one case of woman sexual assault and two cases of child abuse. The mean (SD) hospital stay was 7.87 (14.1) days. Less than 3% (n = 2) were admitted to the intensive care unit with no deaths. In conclusion, the majority of patients in our study had minor injuries. Nevertheless, the psychological impact may be major. This highlights the need to develop suitable mental health services in support of victims of interpersonal violence.

    Interfacial issues, such as the interfacial structure and the interdiffusion of atoms at the interface, are fundamental to the understanding of the ignition and reaction mechanisms of nanothermites. This study employs first-principle density functional theory to model Al/MoO3 by placing an Al adatom onto a unit cell of a MoO3(010) slab, and to probe the initiation of interfacial interactions of Al/MoO3 nanothermite by tracking the adsorption and subsurface-penetration of the Al adatom. The calculations show that the Al adatom can spontaneously go through the topmost atomic plane (TAP) of MoO3(010) and reach the 4-fold hollow adsorption-site located below the TAP, with this subsurface adsorption configuration being the most preferred one among all plausible adsorption configurations. Two other plausible configurations place the Al adatom at two bridge sites located above the TAP of MoO3(010) but the Al adatom can easily penetrate below this TAP to a relatively more stable adsorption configuration, with a small energy barrier of merely 0.2 eV. The evidence of subsurface penetration of Al implies that Al/MoO3 likely has an interface with intermixing of Al, Mo and O atoms. These results provide new insights on the interfacial interactions of Al/MoO3 and the ignition/combustion mechanisms of Al/MoO3 nanothermites.

    Novel Al-based composites (Al-C-Cu-Al 2 O 3 ) obtained by mechanical milling (MM), were characterized by transmission electron microscopy (TEM) and electron energy loss spectroscopy (EELS). Analyses of composites were carried out in both, the as-milled and the as-sintered conditions. C nanoparticles were found in the as-milled condition and Al 2 O 3 nanofibers were found in as-sintered products, as determined by EELS. C and Cu react with Al to crystallize in Al 3 C 4 and Al 2 Cu structures, respectively

  6. Atomistic simulations of diffusion mechanisms in off-stoichiometric Al-rich Ni3Al

    2007-01-01

    This paper presents dynamics simulation results of diffusion in off-stoichiometric Al-rich Ni 3 Al (Ni 73 Al 27 ) at temperature ranging from 1300 to 1550 K. The interatomic forces are described by the Finnis-Sinclair type N-body potentials. Particular attention is devoted to the effect of the extra 2% of Al atoms sitting on the Ni sublattice as antisite point defects (Al Ni ) on diffusion. Simulation results show that Ni atoms mainly diffuse through the Ni sublattice at the temperatures investigated. Al atoms diffuse via both the intrasublattice and antistructure bridge (ASB) mechanisms. The contribution to Al diffusion from the ASB mechanism decreases at the lower temperature (T Ni ) enhances both Al and Ni diffusion in Ni 73 Al 27 . The Ni-Al coupled diffusion effect is observed and understood at the atomic level for the first time

    Rafael, R.; Puyoo, E.; Malhaire, C.

    2017-11-01

    In this work, the electrical transport in Al/Al2O3/Al junctions under mechanical stress is investigated in the perspective to use them as strain sensors. The metal/insulator/metal junctions are elaborated with a low temperature process (≤200 °C) fully compatible with CMOS back-end-of-line. The conduction mechanism in the structure is found to be Fowler-Nordheim tunneling, and efforts are made to extract the relevant physical parameters. Gauge factors up to -32.5 were found in the fabricated devices under tensile stress. Finally, theoretical mechanical considerations give strong evidence that strain sensitivity in Al/Al2O3/Al structures originates not only from geometrical deformations but also from the variation of interface barrier height and/or effective electronic mass in the tunneling oxide layer.

  10. METRIC context unit architecture

    Energy Technology Data Exchange (ETDEWEB)

    Simpson, R.O.

    1988-01-01

    METRIC is an architecture for a simple but powerful Reduced Instruction Set Computer (RISC). Its speed comes from the simultaneous processing of several instruction streams, with instructions from the various streams being dispatched into METRIC's execution pipeline as they become available for execution. The pipeline is thus kept full, with a mix of instructions for several contexts in execution at the same time. True parallel programming is supported within a single execution unit, the METRIC Context Unit. METRIC's architecture provides for expansion through the addition of multiple Context Units and of specialized Functional Units. The architecture thus spans a range of size and performance from a single-chip microcomputer up through large and powerful multiprocessors. This research concentrates on the specification of the METRIC Context Unit at the architectural level. Performance tradeoffs made during METRIC's design are discussed, and projections of METRIC's performance are made based on simulation studies.

    1993-01-01

    The interfacial phenomena occurring during the contacting of liquid Al-B, Al-Ti-B, and Al-Zr-B melts with KF-AlF 3 liquid fluxes have been investigated by optical examination of quenched metal drops previously immersed in the liquid fluxes. Reactions in the Al-B/KF-AlF 3 system involve the formation of metastable AlB 12 at the metal/flux interface. At high KBF 4 levels in the flux, the AlB 12 is dispersed in the flux and also at low KBF 4 levels in the metal. Reactions in the Al-Ti-B/KF-AlF 3 system involve the formation of TiB 2 , which may be dispersed in either the metal or the flux depending upon the composition of the flux. The results obtained for the Al-Ti-B/NaF-AlF 3 and Al-Zr-B/KF-AlF 3 systems were similar to those observed for the Al-Ti-B/KF-AlF 3 system

    2010-02-01

    Full Text Available Al2O3 particle-reinforced ZL109 composite was prepared by in situ reaction between CuO and Al. The microstructure was observed by means of OM, SEM and TEM. The Al2O3 particles in sub-micron sizes distribute uniformly in the matrix, and the Cu displaced from the in situ reaction forms net-like alloy phases with other alloy elements. The hardness and the tensile strength of the composites at room temperature have a slight increase as compared to that of the matrix. However, the tensile strength at 350 ℃ has reached 90.23 MPa, or 16.92 MPa higher than that of the matrix. The mechanism of the reaction in the CuO/Al system was studied by using of differential scanning calorimetry(DSC and thermodynamic calculation. The reaction between CuO and Al involves two steps. First, CuO reacts with Al to form Cu2O and Al2O3 at the melting temperature of the matrix alloy, and second, Cu2O reacts with Al to form Cu and Al2O3 at a higher temperature. At ZL109 casting temperature of 750–780 ℃, the second step can also take place because of the effect of exothermic reaction of the first step.

    2003-01-01

    Spray-formed Al-Fe alloys having undergone high-speed deformation were examined under a high-voltage electron microscope. Two types of specimens were examined; one containing fine Al 13 Fe 4 particles, and the other containing large particles. In the former specimen, deformation is found to proceed in three patterns, depending on specimen thickness and strain rate: (1) without deformation of the Al 13 Fe 4 ; (2) breaking of the Al 13 Fe 4 ; or (3) melting of the Al 13 Fe 4 . Local melting is found to alter some of the Al 13 Fe 4 particles, to impart five-fold symmetry in diffraction or an amorphous structure. In the latter specimen, introduction of glide dislocations enabled us to determine a shear system in the mc102 monoclinic c2/m crystal of Al 13 Fe 4 . On the bases of these observations, the mechanism of high-speed deformation is discussed while taking into account the highly stressed and/or heated states of Al 13 Fe 4 embedded in Al matrix

Iniciada su carrera en 1999 con M., ha publicado títulos como Lo spazio sfinito (2000 y Un amore dell'altro mondo (2002, en el que narra la vida de Kurt Cobain, líder del grupo Nirvana, a través de la visión de un amigo imaginario. A estas dos novelas siguieron La ragazza che non era lei (2005, Gli alieni (2006 o Cinacittà. Memorie del mio delitto efferato (2008, ambientada en una Roma colonizada por los chinos y abandonada por los mismos romanos a causa de problemas medioambientales. Títulos como L'hotel a zero stelle (2011, un ensayo autobiográfico en el que plantea diálogos ficticios con algunos de los grandes nombres de la literatura o la más reciente Panorama (2015, le han hecho valerse un hueco provilegiado entre los nuevos narradores surgidos en estas primeras décadas de siglo. Justamente la publicación de esta última novela, Panorama, ha servido de excusa al profesor Franco Zangrilli, gran conocedor de su obra, a plantearle algunas preguntas sobre temas clave de su producción.

Ortiz Valdivieso, orquídeologo y mutisiólogo y del Dr. Uribe Angel notable historiador educativo, y presentado admirablemente por el P. Durán Casas, Vicerrector Académico de la Universidad Javeriana. En el prólogo, citando desde Sarton y Ziman en los 70s. hasta Mauro Torres en el 2011 afirmo que, aunque suene extraño, parece como si las Academias florecieran entre las guerras. Tal sucedió con la de Platón, “la máxima institución de enseñanza superior surgida en el mundo”, -al decir de Sartonenmarcada desde las guerras del Peloponeso, hasta el final de la dominación espartana de Atenas en el siglo IV antes de Cristo. Según dichos autores, las Academias han simbolizado una manera de continuar la vida espiritual entre uno y otro conflicto.
