philosophy, and its accompanying narrative of development.
Ancient understanding viewed reality as a series of descending steps,
starting with the most ineffable and most simple which is first unfolded
through divinity and then moves down through varying conditions of
existence – the highest of which are closest to the originating simplicity
and are purely intelligible, but the lower being increasingly complex and
changeable, ultimately becoming perceptible to the senses. These lower
conditions of existence were not rejected as evil or illusive, but they were
seen as deriving their worth and trustworthiness from their relation to the
highest. Each plane of reality had its answering correspondence in the
nature of the human being. Since the highest levels possessed the greatest
intelligibility and stability, it was here that philosophers sought to centre
the art and science of philosophy. For this reason philosophy was seen as
an interior discipline which allowed a conscious and active participation in
a divine and intellectual drama – in more modern terms it was considered
to be a spiritual path, or a yoga of enlightenment.

fragment about the bow and the lyre, where their “backstretched” or “retroflex” harmony (palmtonos harmonia) is
said to depict the tense inner cohesion of a diverging unity.
The same authority, Heraclitus of Ephesus, employs a Greek
pun to show how in the bow itself, one of whose names is bios,
both the name of life and the act of death coexist. Orpheus, as
a mythical hero—indeed, one of the famed Argonauts—stands
right at the centre of these junctions. So it is no wonder that
this book shares in that harmonious tension: a tension rooted
in the nature of the lyre and the bow, whose products may be
piercing sounds or slaying arrows.
Here, we have first a tension within the author, who is intoxicated with his theme and yet committed to carry out his
exposition in a discursive and academic manner. We can almost feel his plight: having in mind the “tremendous contem
plation of the divine truth and beauty”, which would merit
cither a bakchic outburst or a “supra-noetic metaphysical silence”, he is forcing himself to compose a “scientific” treatise.
Having heard the music of O rpheus’ lyre, he is trying to convey as best as he can the unspeakable beauty of those notes in
an all too earthly human language.

activities involved in the production and reception of films” and “the variety of ways in which
the film text is intermeshed with a whole set of economic, technological, social, and cultural
practices” (Hill xix), scholars continue to engage in extended, often markedly philosophical
studies of films themselves. Using analytic methods that owe “much to art history” and literary
theories, film scholarship that carefully, intelligently, and sometimes painstakingly explicates
meanings created by narrative and cinematic choices in individual films constitutes a line of
research that is quite different from work that ‘looks past the screen’ to understand audience
reception, regulatory systems (especially censorship), and the many material facets of industrial
media production (Smoodin 2). And so, while historical moments of cinephilia might be most
readily associated with the art journals and film clubs of the silent era and later with the
collection of critics in France and the U.S. who shaped filmmaking and popular taste in the
1960s, one can see that cinephilia still or now finds passionate expression in scholarship that to
some degree locates “the site of aesthetic production [in] the mind of the critical spectator” but
also aims to achieve an “Arnoldian ideal of critical disinterestedness” that is distinguished by
“sensitive response” and informed, circumspect textual analysis (Taylor 150, 157).

taking into account the reading needed to develop one's word phraseology. Part of the problem is where to
start, and how to write an odor description. The book was created due to my desire to share my notes to an
art that is fascinating only understood well by a few. It is based on many years of work including an extensive bibliography of reference sources including my own notes.

The technology and materials for vegetating roofs and creating usable open spaces over structure ... more The technology and materials for vegetating roofs and creating usable open spaces
over structure have been known for centuries. Since 4000 BC, practitioners of
building and agriculture have utilized the knowledge and materials of their time to
construct sacred places such as ziggurats, simple vegetated roofs, and remarkable gardens over elevated surfaces.
The building green movement is not new, nor is the practice of using natural
resources responsibly to sustain life and encourage the regeneration of natural resources.
In the last five years, the term green roof has taken on ecological and social significance beyond its seemingly simplistic description. As commonly understood, the term
has become an epithet for the reduction of pollution and urban heat islands, for largescale mitigation of stormwater runoff, and for maximum utilization of urban land.
Justifiably, the concept of the green roof as a way to add pervious surface and usable
open space without taking up additional land is easy to understand and should be equally
easy to implement. Consequently, many clients, municipalities, architects, landscape architects, and planners have come to consider them as an integral element of sustainable
building practice.

Technical people need to be aware of many things. One study said that a coating chemist must be proficient
in 27 different disciplines. This book is directed at supplying a broad cross-index of some of the different
aspects to help the technical person. It is not meant to be an in-depth treatise on any subject. It is meant
to give insight into the various subjects covered. The chapter authors or the editor may be contacted for
more information or direction on the subjects.
To aid the person involved in coatings, inks, or adhesives, be they chemists, engineers, technicians,
researchers, or manufacturers, chapters are given in the areas of fundamentals and testing, coating and
processing, techniques and materials, and surface coatings. Each section contains information to expand
the awareness and knowledge of someone practicing in the field. The objective is to help people solve
problems and increase their level of technology. With time, technology increases, as shown by the chapter
on statistical design of experiments, and the chapter on using equipment to determine ultraviolet (UV)
resistance. Newer materials such as fluorocarbon resins, polyurethane thickeners, and high-temperature
pigments are included as well as older materials such as alkyds, clays, and driers.
To accomplish the presentation of technology, this book has been expanded to 118 chapters by adding
new material and updating other material. Hopefully, the reader will expand his or her knowledge and
further push the envelope of technology.
The editor gratefully acknowledges the many contributions of the chapter authors and the publishers
who have made this book possible.

The term "alkyd" was coined by Kienle and Ferguson 1 and is derived from "al" of alcohol and "cid" of acid; "cid" was later changed to "kyd." Alkyd resins in a broad sense refer to polymers. By convention, however, polyesters with unsaturation in the backbone are not referred to as alkyds but are termed "unsaturated polyesters." The specific definition of alkyds that has gained wide acceptance is that alkyds are polyesters modified with fatty acids. The nonmodified resins are then called saturated polyesters. Terms like "oil-free alkyd" and "oil-modified polyester" can also be found in the literature. 51.1 Classification Alkyds are synthesized from three basic components: polybasic acids, polyols, and (except for oil-free alkyds) fatty acids. The nature and proportions of these components control the properties of the resin. The amount of combinations is enormous, and specification of an alkyd resin must involve several parameters. The most important ways of classifying are given below.

These mushrooms represent a growing problem regarding hallucinogenic drug abuse. Despite its experimental medical use in the 1960s, only very few pharmacological data about psilocybin were known until recently. Because of its still growing capacity for abuse and the widely dispersed data this review presents all the available pharmacological data about psilocybin.

prepared soil maps for much of the country. Both field and laboratory data are used to design map
units and provide supporting information for scientific documentation and predictions of soil behavior. A
soil map delineates areas occupied by different kinds of soil, each of which has a unique set of
interrelated properties characteristic of the material from which it is formed, its environment, and its
history (Soil Survey Division Staff, 1993). The soils mapped by the NCSS are identified by names that
serve as references to a national system of soil taxonomy (Soil Survey Staff, 1999). Coordination of
mapping, sampling site selection, and sample collection in this program contributes to the quality
assurance process for laboratory characterization (Burt, 1996). Requisites to successful laboratory
analysis of soils occur long before the sample is analyzed (USDA, Soil Conservation Service, 1984; Soil
Survey Staff, 1996). In the field, these requisites include site selection, descriptions of site and soil
pedon, and careful sample collection. A complete description of the sampling site not only provides a
context for the various soil properties determined but also is a useful tool in the evaluation and
interpretation of the soil analytical results (Patterson, 1993). Landscape, landform, and pedon
documentation of the sampling site serves as a link in a continuum of analytical data, sampled horizon,
pedon, landscape, and overall soil survey area. The method described herein is after the Soil Survey
Staff.

endured through time and history to assuage the ills of humankind and assist in the prevention of
further diseases and imbalances of health. Chinese herbal medicine is notable for its sophistication
in addressing clinical concerns while remedying an individual’s particular needs. Thousands of
years old, the herbal medicine tradition remains a vibrant player in today’s health field.
Chinese Herbal Medicine: Modern Applications of Traditional Formulas, written by Dr. Chongyun
Liu and Angela Tseng, is the newest addition to the busy clinician’s repertoire. With over 20 years
of clinical experience, Dr. Liu supplies more than 860 formulas with descriptions of appropriate
customization that will enable practitioners to tailor herbal formulas to meet patients’ needs. In
addition, a listing of over 640 individual herbs provides quick access to clinical modifications. Of
significant note is the extensive review of 190 allopathic medical conditions with corresponding
traditional Chinese medicine diagnoses and formulations.
The publication of this text is another step forward in bringing Chinese medicine to the forefront
of the integration between Eastern and Western medicine. May this book guide and assist practitioners and students of traditional Chinese medicine in their lifetime pursuit of excellence on the
journey of clinical study.

In an attempt to tease out the relationship between these elements, this study tested the effects of the hallucinogenic mixed 5-HT 1A/2A receptor agonist psilocybin alone and after pretreatment with the 5-HT 2A antagonist ketanserin. Eight healthy human volunteers were tested on a multiple-object tracking task and spatial working memory task under the four conditions: placebo, psilocybin (215 Ag/kg), ketanserin (50 mg), and psilocybin and ketanserin. Psilocybin significantly reduced attentional tracking ability, but had no significant effect on spatial working memory, suggesting a functional dissociation between the two tasks. Pretreatment with ketanserin did not attenuate the effect of psilocybin on attentional performance, suggesting a primary involvement of the 5-HT 1A receptor in the observed deficit. Based on physiological and pharmacological data, we speculate that this impaired attentional performance may reflect a reduced ability to suppress or ignore distracting stimuli rather than reduced attentional capacity. The clinical relevance of these results is also discussed. &

a variety of tree species. Due to its ease of cultivation and its
pungent flavor, Shiitake is being considered as an alternative
crop in many areas of the United States. Shiitake have been
used in the Orient for about 2000 years, but have only been
commercially cultivated since 1940. About 160,000 metric
tons are produced annually in Japan, half of which is dried and
exported. It represents a two billion dollar industry which
employs about 200,000 people.

Pharmacological challenge with the 5-HT 2A agonist psilocybin (PY) is useful in studying the neurobiological basis of cognition and consciousness. Objective Investigation of dose-dependent effects of PY on psycho(patho)logical and physiological parameters. Methods Eight subjects received placebo (PL), and 45 (very low dose, VLD), 115 (low dose, LD), 215 (medium dose, MD), and 315 (high dose, HD) g/kg body weight PY. The Altered States of Consciousness Rating Scale (5D-ASC), the Frankfurt Attention Inventory (FAIR), and the Adjective Mood Rating Scale (AMRS) were used to assess the effects of PY on psycho(patho)logical core dimensions, attention, and mood. A 24-h electrocardiogram (EKG) was recorded and blood pressure was measured. Plasma concentrations of thyroid-stimulating hormone (TSH), prolactin (PRL), cortisol (CORT), adrenocorticotropic hormone (ACTH), and standard clinical chemical parameters were determined. Results PY dose dependently increased scores of all 5D-ASC core dimensions. Only one subject reacted with transient anxiety to HD PY. Compared with PL, MD and HD PY led to a 50% reduction of performance in the FAIR test. General inactivation , emotional excitability , and dreaminess were the only domains of the AMRS showing increased scores following MD and HD PY. The mean arterial blood pressure (MAP) was moderately elevated only 60 min following administration of HD PY. Neither EKG nor body temperature was affected by any dose of PY. TSH, ACTH, and CORT plasma levels were elevated during peak effects of HD PY, whereas PRL plasma levels were increased following MD and HD PY. Conclusion PY affects core dimensions of altered states of consciousness and physiological parameters in a dose-dependent manner. Our study provided no cause for concern that PY is hazardous with respect to somatic health.

commercially cultivated since 1940. About 160,000 metric
tons are produced annually in Japan, half of which is dried and
exported. It represents a two billion dollar industry which
employs about 200,000 people.

Pharmacological challenge with the 5-HT 2A agonist psilocybin (PY) is useful in studying the neurobiological basis of cognition and consciousness. Objective Investigation of dose-dependent effects of PY on psycho(patho)logical and physiological parameters. Methods Eight subjects received placebo (PL), and 45 (very low dose, VLD), 115 (low dose, LD), 215 (medium dose, MD), and 315 (high dose, HD) g/kg body weight PY. The Altered States of Consciousness Rating Scale (5D-ASC), the Frankfurt Attention Inventory (FAIR), and the Adjective Mood Rating Scale (AMRS) were used to assess the effects of PY on psycho(patho)logical core dimensions, attention, and mood. A 24-h electrocardiogram (EKG) was recorded and blood pressure was measured. Plasma concentrations of thyroid-stimulating hormone (TSH), prolactin (PRL), cortisol (CORT), adrenocorticotropic hormone (ACTH), and standard clinical chemical parameters were determined. Results PY dose dependently increased scores of all 5D-ASC core dimensions. Only one subject reacted with transient anxiety to HD PY. Compared with PL, MD and HD PY led to a 50% reduction of performance in the FAIR test. General inactivation , emotional excitability , and dreaminess were the only domains of the AMRS showing increased scores following MD and HD PY. The mean arterial blood pressure (MAP) was moderately elevated only 60 min following administration of HD PY. Neither EKG nor body temperature was affected by any dose of PY. TSH, ACTH, and CORT plasma levels were elevated during peak effects of HD PY, whereas PRL plasma levels were increased following MD and HD PY. Conclusion PY affects core dimensions of altered states of consciousness and physiological parameters in a dose-dependent manner. Our study provided no cause for concern that PY is hazardous with respect to somatic health.

filamentous fungi in combination with synthetic chemistry to provide
novel routes to the family of diterpenes isolated from the Chinese herbal
plant, Tripterygium wivordii. The isolated diterpene triepoxides. Mptolide
(2) and tripdiolide (3), which represent the first reported natural products
containing the 18 (4->3) abeo-abietane skeleton, were of interest since
they have been shown to possess significant anti-neoplastic and
immunosuppressive activity. However. neither T. wivordii plants nor
plant cell cultures yield adequate material for the assessment of
structure-activity relationships. Multi-step syntheses also failed to
provide sufficient quantities. This thesis describes a series of
experiments to functionalize the synthetic diterpene congeners.

in order to provide novel diterpene analogues which bear a close
structural relationship to 2 and 3 and which may be of interest as
biologically active compounds.
