Like De La Fontaine, he recommends preparing canvas with a double ground, but gives much more detail. On the preparation of canvas, he admits that some painters use only the first red ground because the colors sink less: these canvases "font moins mourir les couleurs" and are more easily rolled. Other painters preferred using canvas with a white glue ground for oil paint, which, he adds, appeared to work well. The difficulties of this "new" oil medium continued to trouble La Hire, however, especially the problem of the sinking of the paint layer, particularly in dark colors. He disapproved of those painters who did not apply sufficient layers of paint, finishing with what he considered only an ebauche (sketch), using little pigment and lots of oil, as if painting a glaze. If there was not sufficient paint in the upper layers, he warned, the top paint layer would sink into the layer underneath, a process he called emboire. Emboire was caused by painting on a ground that had not dried sufficiently, or painting on a still wet paint layer, or using excessive oil, especially oil of turpentine. Massing 23 did sink, however, he suggested applying with a small sponge a layer of nut oil mixed with a siccative before continuing to paint. He added that although this layer should dry before adding further details, it was possible to paint fine lines of architectural elements while the layer is still wet (1 2). The prodigious growth of the dyeing and textile industries in the eighteenth century was a contributing influence. Porcelain manufacture, too, was indi rectly responsible for many publications concerning materials, especially pig ments, that could be used for painting. From 1 737, Salon exhibitions of the Academy began to be reviewed by newspapers such as Mercure de France; these reviews sometimes included technical information. The Journal des Sfavans was a fundamental journal for the dissemination of scientific information in the seventeenth and eighteenth centuries, appearing from 1 665 until 1 825, with a few lapses in publishing. Information relevant to the history of painting techniques was often included; the treatises by Antoine Raphael Mengs and Gerard de Lairesse, for example, were discussed at length (1 5). B y the mid-eighteenth century there were many periodicals i n which articles on painting materials or techniques could be found: Observations periodiques sur la physique, et les beaux-arts, Annales de chemie, the Bibliotheque physio-econ omique, instructive et amusante, the Magasin encyclopedique, and the Journal des Sciences, to mention a few of the most important periodicals (1 6). The in creased economic interaction between France and England in the later half of the eighteenth century is reflected in articles in the Journal Oeconomique (1 7). Many articles in these French journals were translated from English publications, including those of the royal societies in London. From Encyclopedie ou diction naire raisonne des sciences, des arts, et des metiers. There were precedents for the Encyclopedie of course, although the early dic tionaries were much smaller, usually two volumes. In the field of the arts, the important sources were Thomas Corneille, Dictionnaire des Arts et Sciences (Par is 1 694); Antoine Furetiere, Dictionnaire universels (The Hague-Rotterdam 1 690); and the Dictionnaire de Trevoux issued by the Jesuits (Aix 1 704). These sources were pillaged by Diderot, following the usual practice of the time (20). Both Lacombe (1 752) and Macquer (1 766) wrote "portable" dictionaries, as did many others (2 1). In the preface to his Dictionnaire portatif de peinture, sculpture et gravure (Paris 1 757), Pernety even apologized for producing yet another dictionary. We are inundated, and if this torrent is not stopped, we will be learning only from dictionaries. We want to know every thing-or rather speak if every thing and pretend to be ignorant if nothing. J J Encaustic painting the history of oil painting was an eighteenth-century fascination. In the mid eighteenth century Diderot still believed, as De La Fontaine previously as serted in his seventeenth-century treatise, that the art of painting was reborn when "Jean de Bruges" Gan van Eyck) discovered the "secret" of oil painting. It was generally accepted that the Ancient painters possessed superior tech niques, and that it should be possible to "rediscover" their methods. By the eighteenth century there was also concern about the state of seventeenth century paintings, which no longer retained the freshness of those more re cently painted (23). Diderot and the painter Bachelier were also interested in the experiments with encaustic or colored wax.

The process medications related to the female reproductive system buy 8mg zofran visa, as described by Palma Giovane walmart 9 medications purchase zofran 4 mg with amex, is distinctly different from the earlier manner in which Titian painted medications on a plane purchase zofran 8mg overnight delivery. This difference was already noticed by Vasari in 1 566: 1 20 Historical Painting Techniques medications 5 rs order 4 mg zofran amex, Materials, and Studio Practice For the early works are executed with a certain finesse and an incredible diligence, so that they can be seen from close as well as from a distance while these last pictures are executed with broad and bold strokes and smudges, so that from nearby nothing can be seen whereas from a distance they seem peifect. Where visible in infrared reflectography, the underdrawing seems to have been closely followed. Observed under a stereo microscope, many lumps of pigment are visible, suggesting that in making the paint, the pigments were not really ground into, but simply stirred into the oil. Some differences can be noted between the version in the Getty and the one in the Prado. Judging from the development as de scribed by the two contemporary comments, the Getty painting is more loosely executed than the Prado version, and must have been made at a later date, perhaps around 1 560. The National Gallery version can definitely be considered to have been painted after the Getty and Prado versions. The yellow pig ment had all the optical characteristics of orpiment, including a laminated form and a waxy luster of the fairly large crystalline particles. The identifi cation of orpiment was confirmed by finding larger amounts of arsenic in the sample. These pigments were identified by the usual means of microscopic and microchemical analysis. The use of orpiment and realgar in European easel paintings is comparatively rare, but it is not unusual to find them in Venetian painting; the use of orpiment occurred more often in manuscript illuminations. This lack of pop ularity may be due to the fact that both pigments are highly poisonous, and good alternatives, such as lead-tin yellow or yellow lakes for orpiment or vermilion for realgar, were readily available. Because of their sulfidic nature, both orpiment and realgar are not very compatible with many other pigments. The Theophilus manuscript even states that orpiment cannot be mixed with any other color because it would destroy them. While realgar was sometimes used to prevent putrefaction of binding media by bacteria, fungi, and micro organisms, historical recipes describing the use of realgar as an actual pigment are extremely rare (7). Considering their drawbacks, it is surprising to see how frequently these pigments were used in sixteenth-century Venetian painting. They have been identified in several paintings by Titian and Giorgione and in many paintings by Tintoretto and Bassano. Both mineral substances could not be found in the immediate vicinity and had to be imported. They are conspicuously absent in paintings made in the area around Naples where the minerals actually do occur in the fumaroles near Mount Vesuvius. Their frequent use in sixteenth-century Ven ice may relate to the increasing use of oil as the paint medium. The radiant brilliance of their color in this new medium may have contributed to their popularity. Samples taken from the deep blue of the mountain range appear under the microscope as pale blue, splintery particles with a low re fractive index (n < 1. In the cross section, one can see a single layer of densely packed blue particles. Gettens and Stout suggest that the earliest occurrence of cobalt colored glass in Europe may have been in the early fifteenth-century Venetian fran is glass industry (8). A recipe in a fifteenth-century treatise already mentions the prep aration of smalt as a smalto cilestro (9). The source of the smalt in the Getty painting may have been Saxony or Bohemia, where sixteenth-century glassmakers used the locally mined co baltite (CoAsS) and smaltite (CoAs2) minerals, which contain large amounts of arsenic, to make smalt. It is unclear whether the ffer of Italian descriptions, has the same composition as the north zafran, or za ern European cobaltite. Examination of cross sections of those areas shows that the pale blue consists of a layer of almost completely discolored glassy particles. In a sample taken from the seat, an organic colorant was found that also showed the presence of a few textile fibers. This led us to believe that the red lake may very well have been a so-called lacca de cimatura de grana. The making of such lakes was a fairly common practice, and its description can be found in numerous fif teenth- and fourteenth-century recipe texts (1 0).

The solid lines indicate variation, beginning from the seeds, as the participants enroll in the survey. When the solid lines rest upon the dotted lines that represent the nal weighted estimate for each of the categories, convergence has been reached. This may be because the networks of males and females who inject drugs are substantially different. When the samples were nally gathered, there were so few females in the sample that the estimates ended up representing the network of males who inject drugs only. All surveys were conducted in existing health clinics, for which there were no charges. Planning and data collection time Both methods require the submittal and approval of a protocol, which can take between one to six months. For instance, past surveys of migrants may have found that 20% of migrants 206 have experienced discrimination at a healthcare facility.

Conroy, Deirdre Ni Cheallaigh, and Elaine Byrne Abstract the chapter covers key features of self-stigma and methods to measure it. We rst present several challenges in de ning self-stigma, notably the need to consider its complex nature. We describe methods to assess not only how much, but also why self-stigma is being experienced. We recommend a new measure, the Ryff Scales of Psychological Wellbeing, to help shift the scope of measurement away from purely assessing negative personal experiences toward a more holistic and supportive approach. This chapter may also be useful to those involved in developing interventions to address self-stigma. Other users may bene t from applying the recommended measurement tools to improve their understanding of how self-stigma may affect their programs. Introduction One of the major challenges in measuring self-stigma is the approach and the terminology used.

Other symptoms of hypothyroidism include weight gain symptoms 6dp5dt discount zofran 8 mg with visa, decreased libido symptoms brain tumor cheap 8mg zofran with amex, inability to tolerate cold symptoms nausea dizziness effective 4mg zofran, muscle pain and spasm medicine ubrania generic zofran 4mg with amex, and brittle nails. Hypothyroidism in children, a condition known as cretinism, can result in mental retardation, dwarfism, and permanent sexual immaturity. Sometimes the thyroid gland produces too much thyroxine, a condition known as hyperthyroidism. This condition produces symptoms such as an abnormally high body temperature, profuse sweating, high blood pressure, loss of weight, irritability, insomnia and muscular pain and weakness. It also causes the characteristic symptom of the eyeballs protruding from the skull called exopthalmia. This is surprising because it is not a symptom usually related to a fast metabolism. Hyperthyroidism has been treated by partial removal or by partial radiation destruction of the gland. More recently, several drugs that inhibit thyroid activity have been discovered, and their use is replacing the former surgical procedures. T3 and T4 Function within the body Iodine and T4 stimulate the spectacular apoptosis (programmed cell death) of the cells of the larval gills, tail and fins Transforming the aquatic, vegetarian tadpole into the terrestrial, carnivorous frog with better neurological, visuospatial, olfactory and cognitive abilities for hunting. Contrary to amphibian metamorphosis, thyroidectomy and hypothyroidism in mammals may be considered a sort of phylogenetic and metabolic regression to a former stage of reptilian life. Indeed, many disorders that seem to afflict hypothyroid humans have reptilian-like features, such as dry, hairless, scaly, cold skin and a general slowdown of metabolism, digestion, heart rate and nervous reflexes, with lethargic cerebration, hyperuricemia and hypothermia (Venturi, 2000). Their release will be increased under certain situations such as cold temperatures when a higher metabolism is needed to generate heat. When children are born with thyroid hormone deficiency they have problems with physical growth and developmental problems. Brain development can also be severely impaired the significance of iodine Thyroid hormone cannot be produced without an abundant source of iodine. The iodine concentration within the body, although significant, can be as little as 1/25th the concentration within the thyroid itself. When the thyroid is low on iodine the body will try harder to produce T3 and T4 which will often result in a swelling of the thyroid gland, resulting in a goiter. Extrathyroidal iodine Iodine accounts for 65% of the molecular weight of T4 and 59% of the T3. Its role in mammary tissue is related to fetal and neonatal development, but its role in the other tissues is unknown. However, the thyroid gland needs no more than 70 micrograms /day to synthesize the requisite daily amounts of T4 and T3. These higher recommended daily allowance levels of iodine seem necessary for optimal function of a number of body systems, including lactating breast, gastric mucosa, salivary glands, oral mucosa, thymus, epidermis, choroid plexus, etc. It is an additional hormone produced by the thyroid, and contributes to the regulation of blood calcium levels. It can also be used therapeutically for the treatment of hypercalcemia or osteoporosis. Without this hormone calcium will stay within the blood instead of moving into bones to keep them strong and growing. Its importance in humans has not been as well established as its importance in other animals. They are small, light-colored lumps that stick out from the surface of the thyroid gland. They are butterfly-shaped and located inside the neck, more specifically on both sides of the windpipe. Another function of the parathyroid glands is to secrete parathyroid hormone, which causes the release of the calcium present in bone to extracellular fluid. There are two major types of cells that make up parathyroid tissue: One of the major cells is called oxyphil cells. The structure of a parathyroid gland is very different from that of a thyroid gland. The chief cells that produce parathyroid hormone are arranged in tightly-packed nests around small blood vessels, quite unlike the thyroid cells that produce thyroid hormones, which are arranged in spheres called the thyroid follicles. It is released directly into the bloodstream and travels to its target cells which are often quite far away. It then binds to a structure called a receptor, that is found either inside or on the surface of the target cells.
