Cemís are either transportable artifacts and embodiments of people or spirit, which the Taínos and different natives of the larger Antilles (ca. advert 1000-1550) considered as numinous beings with supernatural or magic powers. This quantity takes a detailed examine the connection among people and different (non-human) beings which are imbued with cemí strength, particularly in the Taíno inter-island cultural sphere encompassing Puerto Rico and Hispaniola. The relationships deal with the $64000 questions of identification and personhood of the cemí icons and their human “owners” and the results of cemí gift-giving and gift-taking that sustains a fancy net of relationships among caciques (chiefs) of Puerto Rico and Hispaniola.
 
Oliver offers a cautious research of the 4 significant kinds of cemís—three-pointed stones, huge stone heads, stone collars, and elbow stones—as good as face mask, which supply an attractive distinction to the stone heads. He unearths facts for his interpretation of human and cemí interactions from a severe overview of 16th-century Spanish ethnohistoric files, specifically the Relación Acerca de las Antigüedades de los Indios written by way of Friar Ramón Pané in 1497–1498 lower than orders from Christopher Columbus. Buttressed via examples of local resistance and syncretism, the quantity discusses the iconoclastic conflicts and the connection among the icons and the people. concentrating on this and at the a variety of contexts within which the relationships have been enacted, Oliver finds how the cemís have been vital to the workout of local political energy. Such cemís have been thought of a right away danger to the hegemony of the Spanish conquerors, as those effective gadgets have been visible as allies within the local resistance to the onslaught of Christendom with its icons of saints and virgins.

These essays at the conceptual realizing of contemporary physics strike at once at a number of the crucial problems confronted by means of modern philos­ ophers of actual technological know-how. furthermore, they reverberate to previous and classical struggles with these problems. every one of those essays can be obvious as either a remark on our predecessors and an unique analytic interpretation. they arrive from paintings of the earlier decade, so much from conferences of the Boston Colloquium for the Philosophy of technology, and so they show back how difficult the basics of our figuring out of nature nonetheless are. the topics will appear to be customary however the adaptations aren't simply creative but additionally stimulating, in many ways counterpoint. And so once more we're faced with problems with area and time, irreversibility and dimension, subject and technique, hypothetical fact and verifiability, rationalization and relief, extra special base and complex concept, unified technology and the solidarity of nature, and the bounds of conventionalism. we're thankful for the cooperation of our participants, and particularly for the contract of George Ellis and C. F. von Weizsiicker to permit us to exploit formerly released papers.

The e-book summarizes our present realizing of the ultrastructure and synaptic association of the mesencephalic trigeminal nucleus (MTN) within the cat in addition to the neurochemistry of its neuronal population.
specific emphasis is given to the survey of synaptic connections and the prospective physiological involvement of MTN inputs within the transmission of proprioceptive info. utilizing immunocytochemistry and in situ hybridization
histochemistry we've pointed out detailed neuronal, partially chemically coded MTN subpopulations - huge glutamatergic and smaller GABAergic neurons. We additionally exhibit that MTN obtain catecholaminergic and peptidergic innervation.
the degrees of transmitter components range in accordance with the environmental stipulations hence implying the neurochemical plasticity of MTN neurons.

Chemosensory Transduction The Detection of Odors, Tastes, by Frank Zufall, Steven D. Munger PDF

By Frank Zufall, Steven D. Munger

ISBN-10: 0128016949

ISBN-13: 9780128016947

Written via leaders within the box of chemosensation, Chemosensory Transduction presents a entire source for realizing the molecular mechanisms that permit animals to observe their chemical international. The textual content focuses on mammals, but additionally comprises a number of chapters on chemosensory transduction mechanisms in reduce vertebrates and bugs. This ebook examines transduction mechanisms within the olfactory, flavor, and somatosensory (chemesthetic) structures in addition to in numerous inner sensors which are liable for homeostatic law of the physique. Chapters disguise such subject matters as social odors in mammals, vertebrate and invertebrate olfactory receptors, peptide signaling in flavor and intestine nutrient sensing. contains a foreword via preeminent olfactory scientist Stuart Firestein, Chair of Columbia University’s division of organic Sciences in manhattan, NY.

Chemosensory Transduction describes cutting-edge techniques and key findings concerning the learn of the chemical senses. therefore, it serves because the go-to reference for this topic for working towards scientists and scholars with backgrounds in sensory biology and/or neurobiology. the amount may also be useful for researchers engaged within the layout or trying out of flavors, fragrances, meals and/or pharmaceuticals.

  • Provides a complete evaluate for all chemosensory transduction mechanisms
  • Valuable for teachers taken with sensory biology, neurobiology, and chemosensory transduction, in addition to researchers in new taste, perfume, and meals testing
  • Edited via major specialists within the box of olfactory transduction
  • Focuses on mammals, yet decrease vertebrates and invertebrate version platforms also are included

Eine Unterteilung des 1. Bandes dieses Handbuches warfare aus mehreren Grunden erforderlich. Die Fiille des fabrics hatte nur einen Band zu umfangreich gemacht. Noch wichtiger ist aber die Tatsache, daB zum Thema "Physik und Technik" sehr heterogene Kapitel gehOren. Bei einem Teil des zu bearbeitenden Stoffes ist heute, wenigstens aus medizinischer Sicht, bereits ein gewisser AbschluB erreicht. Andere Ge biete sind aber noch so sehr in geradezu stiirmischer Weiterentwicklung, daB ihre "ab schlieBende handbuchmaBige" Bearbeitung nicht und wahrscheinlich sogar nie moglich ist. Aus diesem Grunde wurden die vorwiegend "technologischen" Kapitel iiber die Er zeugung von Rontgenstrahlen, iiber Elektronenbeschleuniger und Erzeuger ultraharter Strahlungen sowie iiber die Gerate fiir die Anwendung ionisierender Strahlen in einem Teilband zusammengefaBt. Den Verfassern dieser Kapitel (JENSEN; BERGER u. WACHSMANN; BISCHOFF u. GELLINEK) schulden wir besonderen Dank; ihre Aufgabe struggle namlich schwer. Fiir dieses Handbuch kam es darauf an, aus dem ungeheuren Spektrum der Apparate-, Rohren- und Gerateentwicklung das Wesentliche, d.h. die Grundprinzipien heraus zuarbeiten und markante Beispiele fiir deren praktische Verwirklichung darzustellen. Diese Kapitel diirften keinesfalls ausschlieBlich zu einem "Katalog" derzeit gebrauch licher Apparate oder Gerate werden. Wir glauben, daB die Autoren diese schwierige gelOst haben. Aufgabe bestens H. VIETEN Diisseldorf, Friihjahr 1965 Preface A subdivision of the 1st quantity of this guide used to be helpful for a number of purposes.
