A Renaissance Depiction of a Tornado.

NASA Astrophysics Data System (ADS)

Hoinka, Klaus P.; de Castro, Manuel

2005-04-01

In the Renaissance, impressive weather features inspired considerable interest among artists. The depiction of a tornado and other weather features are discussed that appear on a sixteenth-century series of 12 huge tapestries (“Conquest of Tunis”) woven by the carpet manufacturer Willem de Pannemaker in Brussels, Belgium, between 1549 and 1551. The outstanding depiction of the tornado is presumably the earliest pictorial presentation of a tornado, at least in the Latin west.During the Renaissance, tapestries were an obligatory fixture of a European court and were used as an instrument for political propaganda and dynastic demonstration. The “Conquest of Tunis” tapestries are important pieces of Eu-ropean art commissioned by the Habsburgian emperor Charles V (1500–58), one of the most important ruling personalities in Euro-pean history. In 1535, he undertook a crusade to Tunis, Tunisia, in order to diminish the Ottoman emperor's power in the western Mediterranean region. Charles V wanted to ensure that the expedition would not be forgotten. In order to guarantee this, the emperor took along the Flemish painter Jan Cornelisz Vermeyen who painted sketches that were used as prototypes for the “Conquest of Tunis” tapestries. These present a highly detailed narrative of the expedition to Tunis.The depiction of a tornado, along with heavy rain and a sandstorm, raises the question of why these meteorological features are included in the scene. To the authors' knowledge, no mention is made of them in the art literature (except for the sandstorm, which actually occurred). This is particularly surprising because the tornado, at least, appears so prominently in one of the tapestries. Therefore, the weather features are discussed in terms of their meteorological, decorative, and symbolic importance. The tornado and the heavy rain seem to have been rendered in order to emphasize symbolically the beginning and ending of the military campaign. Although these

Olfactory function in painters exposed to organic solvents.

PubMed

Sandmark, B; Broms, I; Löfgren, L; Ohlson, C G

1989-02-01

The olfactory receptor cells are in direct contact with the exterior environment, and some chemical agents can impair olfactory function. The olfactory function of 54 painters exposed to organic solvents was compared with that of 42 unexposed referents. A new clinical test validated for the sense of smell was used, the University of Pennsylvania Smell Identification Test. Age, smoking habits, exposure to organic solvents, and medical disorders of importance for the sense of smell were recorded. The painters had a somewhat lower test score than the referents. However, the influence of the exposure variable was not statistically significant in a multiple regression analysis including age and smoking habits. The exposure to organic solvents was low, and therefore an effect of high exposure on olfactory function cannot be ruled out. Since some of the painters had earlier been highly exposed, the effects of high exposure are likely to be reversible.

The NASA is changing its attention from large missions to a greater number of smaller missions with reduced development schedules and budgets. In relation to this, the Renaissance Mission Operations and Data Systems Directorate systems engineering process is presented. The aim of the Renaissance approach is to improve system performance, reduce cost and schedules and meet specific customer needs. The approach includes: the early involvement of the users to define the mission requirements and system architectures; the streamlining of management processes; the development of a flexible cost estimation capability, and the ability to insert technology. Renaissance-based systems demonstrate significant reuse of commercial off-the-shelf building blocks in an integrated system architecture.

Thirty-five male painters in the age group of 20-50 years occupationally engaged in domestic and commercial painting for 5-12 years having blood lead levels (BLL) painters as compared with that of the control group. Significant decreases in RBC and plasma AChE were observed in the exposed group in comparison with controls. RBC and plasma AChE showed a decrease of 18.4% and 18%, respectively, in the exposed group. The findings also indicated a significant negative correlation of both RBC and plasma AChE activities with BLL. The marked reduction observed in both RBC and plasma AChE activity may account for disruption of cholinergic function and result in neurotoxicity among the painters.

Objective We conducted a meta-analysis to quantitatively compare the association between occupation as a painter and the incidence or mortality from lung cancer. Data sources PubMed and the reference lists of pertinent publications were searched and reviewed. For the meta-analysis, we used data from 47 independent cohort, record linkage, and case–control studies (from a total of 74 reports), including > 11,000 incident cases or deaths from lung cancer among painters. Data extraction Three authors independently abstracted data and assessed study quality. Data synthesis The summary relative risk (meta-RR, random effects) for lung cancer in painters was 1.35 [95% confidence interval (CI), 1.29–1.41; 47 studies] and 1.35 (95% CI, 1.21–1.51; 27 studies) after controlling for smoking. The relative risk was higher in never-smokers (meta-RR = 2.00; 95% CI, 1.09–3.67; 3 studies) and persisted when restricted to studies that adjusted for other occupational exposures (meta-RR = 1.57; 95% CI, 1.21–2.04; 5 studies). The results remained robust when stratified by study design, sex, and study location and are therefore unlikely due to chance or bias. Furthermore, exposure–response analyses suggested that the risk increased with duration of employment. Conclusion These results support the conclusion that occupational exposures in painters are causally associated with the risk of lung cancer. PMID:20064777

We report a case of a male painter who visited our outpatient clinic after developing a distinct skin reaction 15 min after the ingestion of a laxative solution containing polyethylene glycol (PEG) prior to colonoscopy. He described suffering from the same skin reaction when he was previously exposed to paints that contained PEG-4000. An exposure challenge test with pure PEG-4000, simulating his workplace conditions, elicited a generalized urticarial reaction. Allergy to PEG should be considered in painters who develop urticarial or other systemic symptoms after handling PEG-containing products. © The Author 2015.

Understanding Factors that Influence Protective Glove Use among Automotive Spray Painters

PubMed Central

Ceballos, Diana; Reeb-Whitaker, Carolyn; Glazer, Patricia; Murphy-Robinson, Helen; Yost, Michael

2017-01-01

Dermal contact with isocyanate-based coatings may lead to systemic respiratory sensitization. The most common isocyanates found in sprayed automotive coatings are monomeric and oligomeric 1,6-hexamethylene diisocyanate (HDI) and isophorone diisocyanate (IPDI). Most spray painters use thin (4–5 mil) latex gloves that are not effective at preventing dermal exposures when spraying isocyanate paints. Personal interviews with collision repair industry personnel and focus groups with spray painters were held to characterize risk awareness, to examine perceptions and challenges concerning protective glove use and selection, and to generate ideas for protective glove use interventions. The most popular gloves among spray painters were thin (4–5 mil) and thick (14 mil) latex. We found that medium to thick (6–8 mil) nitrile were not always perceived as comfortable and were expected to be more expensive than thin (4–5 mil) latex gloves. Of concern is the users’ difficulty to distinguish between nitrile and latex gloves; latex gloves are now sold in different colors including blue, which has traditionally been associated with nitrile gloves. Even though spray painters were familiar with the health hazards related to working with isocyanate paints; most were not always aware that dermal exposure to isocyanates could contribute to the development of occupational asthma. There is a need for more research to identify dermal materials that are protective against sprayed automotive coatings. Automotive spray painters and their employers need to be educated in the selection and use of protective gloves, specifically on attributes such as glove material, color, and thickness.

The work has been aimed at investigating the effects of organic solvent-toluene-upon the painters of the Building Joinery Factory. Studies carried out during 1978-1980 showed an increased level of toluene metabolite (hippuric acid) in painters' urine, as compared to the environmental control group. The highest level of hippuric acid in painters' urine was found in the first period (first six months) of their job. This was not related to an increase in toluene vapours at the workplace. In painters' blood some irregular and rather small modifications of enzymatic activity were exhibited.

The dawn of the third renaissance in surgery.

Hackam, David J

2015-08-01

In this presidential address, I will share my belief that our proud and noble field stands at the dawn of a great renaissance. I further believe that this is the third such renaissance that has occurred in surgery. As described herein, the first renaissance in surgery occurred during the 1600s, which involved a transformation in operative care unlike anything that had been seen since Roman times. This first renaissance was triggered by tumultuous world events but was spurred on by the invention of the printing press. The second renaissance occurred during the 1980s and was triggered by the invention of the computer, which is of equal significance to the printing press 240 years earlier. I believe that this third renaissance shares with the earlier renaissances its transformative nature and its reaction to turmoil, both in the medical and nonmedical worlds. This is a renaissance driven by science, by creativity, and by innovation—resources that are never in short supply within our great profession. Copyright © 2015. Published by Elsevier Inc.

Increased frequency of chromosomal aberrations in railroad car painters.

Piña-Calva, A; Madrigal-Bujaidar, E; Fuentes, M V; Neria, P; Pérez-Lucio, C; Vélez-Zamora, N M

1991-01-01

The purpose of this study was to determine if exposure to paints and solvents contributes to chromosomal alterations in occupationally exposed individuals. A total of 25 male railroad and underground railroad car painters were studied. This group had a mean age of 32.7 y and a mean exposure time of 5.2 y. The results were compared with those obtained for 25 healthy (unexposed) males. The scoring of structural chromosome aberrations clearly revealed an increase in the number of all types of aberrations considered in the population of painters. This suggests that exposure to a combination of chemicals may increase genotoxicity in industrial workers.

The aim of the present study was to comparatively evaluate genomic damage and cellular death in exfoliated oral mucosa cells and peripheral blood from car painters. A total of 24 car painters and 19 healthy controls (non-exposed individuals) were included in this setting. Individuals had epithelial cells from cheek mucosa (left and right side) mechanically exfoliated, placed in fixative and dropped in clean slides which were checked for the specific nuclear phenotypes. A total of 5 μL from peripheral blood was collected for the single cell gel (comet) assay. The results pointed out statistically significant differences (p < 0.05) of micronucleated oral mucosa cells from car painters. In addition, DNA damage was detected in peripheral blood cells by single cell gel (comet) assay. Nevertheless, exposure to car paints did not cause increases other nuclear alterations closely related to cytotoxicity such as karrhyorexis, pyknosis and karyolysis in buccal mucosa cells. In summary, the results of the present study suggest that car painters comprise a high risk group since paints can induce genotoxic and mutagenic effects in peripheral blood and oral mucosa cells, respectively.

Painterly rendered portraits from photographs using a knowledge-based approach

NASA Astrophysics Data System (ADS)

DiPaola, Steve

2007-02-01

Portrait artists using oils, acrylics or pastels use a specific but open human vision methodology to create a painterly portrait of a live sitter. When they must use a photograph as source, artists augment their process, since photographs have: different focusing - everything is in focus or focused in vertical planes; value clumping - the camera darkens the shadows and lightens the bright areas; as well as color and perspective distortion. In general, artistic methodology attempts the following: from the photograph, the painting must 'simplify, compose and leave out what's irrelevant, emphasizing what's important'. While seemingly a qualitative goal, artists use known techniques such as relying on source tone over color to indirect into a semantic color temperature model, use brush and tonal "sharpness" to create a center of interest, lost and found edges to move the viewers gaze through the image towards the center of interest as well as other techniques to filter and emphasize. Our work attempts to create a knowledge domain of the portrait painter process and incorporate this knowledge into a multi-space parameterized system that can create an array of NPR painterly rendering output by analyzing the photographic-based input which informs the semantic knowledge rules.

Perceptions of beauty in Renaissance art.

PubMed

Haughton, Neil

2004-12-01

The Renaissance was a cultural revolution that spread from Florence, in 1400, throughout Italy and into the rest of Europe. Its impetus was the philosophy of Humanism, which strove to resurrect and emulate the literature and art of the ancient Greeks and Romans. Artists had previously been limited to formulaic religious iconography. They now began to reproduce descriptions of classical paintings and copy the antique statues that were being newly rediscovered. The Renaissance artist's perception of beauty was therefore determined by his philosophical environment, his visual experience (the 'period eye'), the demands of his patrons and by attempts to enhance his professional status in society to equal that of poets and architects. The image of Venus portrayed by Botticelli as the idealization of beauty in Renaissance Florence is significantly different from the Venus portrayed by the German artist, Lucas Cranach. The northern European Venus is much less voluptuous than her Italian counterpart but is still inspired by humanist principals and retains considerable sexuality. Raphael's paintings epitomise the idealization of female beauty of this period but, by his own admission they were rarely based on real models. Often the same facial type was repeated in many different paintings. Indeed Renaissance portrait artists tended to avoid realistic interpretation, emphasizing instead the positive attributes of their subjects, both physical and political. Thus, Bronzino's Portrait of a Young Man not only depicts his subject's idealized appearance but also his scholarship, background and potential. The depiction of beauty in Renaissance art is shown to be more complex than a mere photograph-like representation of sexuality or of a person's physical appearance. Instead, Renaissance art created physically perfect images resulting from scholarly expectation, the artist's ambitions and his developing skills.

Psychology's Renaissance.

PubMed

Nelson, Leif D; Simmons, Joseph; Simonsohn, Uri

2018-01-04

In 2010-2012, a few largely coincidental events led experimental psychologists to realize that their approach to collecting, analyzing, and reporting data made it too easy to publish false-positive findings. This sparked a period of methodological reflection that we review here and call Psychology's Renaissance. We begin by describing how psychologists' concerns with publication bias shifted from worrying about file-drawered studies to worrying about p-hacked analyses. We then review the methodological changes that psychologists have proposed and, in some cases, embraced. In describing how the renaissance has unfolded, we attempt to describe different points of view fairly but not neutrally, so as to identify the most promising paths forward. In so doing, we champion disclosure and preregistration, express skepticism about most statistical solutions to publication bias, take positions on the analysis and interpretation of replication failures, and contend that meta-analytical thinking increases the prevalence of false positives. Our general thesis is that the scientific practices of experimental psychologists have improved dramatically.

Effect of reduced use of organic solvents on disability pension in painters

Järvholm, Bengt; Burdorf, Alex

2017-01-01

Objective To investigate whether the decreased use of paints based on organic solvents has caused a decreased risk for neuropsychiatric disorders in painters by studying their incidence in disability pensions. Methods The incidence of disability pension in Swedish painters who had participated in health examinations between 1971 and 1993 was studied through linkage with Swedish registers of disability pension over 1971–2010 and compared with the incidence in other construction workers as woodworkers, concrete workers and platers. When phasing out began in the 1970s, about 40% of paints were based on organic solvents and it had decreased to 4% in 1990s. The analysis was adjusted for age, time period, body mass index and smoking. Results The painters (n=23 065) had an increased risk of disability pension due to neurological diagnosis (n=285, relative risk (RR) 1.92, 95% CI 1.67 to 2.20) and psychiatric diagnosis (n=632, RR=1.61, 95 % CI 1.42 to 1.82). For neurological disorders there was a time trend with a continuously decreasing risk from 1980 onwards, but there was no such trend for psychiatric disorders. Conclusions High exposure to organic solvents increased the risk for disability pension in neurological disorders, and the risk decreased when the use of organic solvents decreased. The painters also had an increased risk of disability pension due to psychiatric disorders, but the causes have to be further investigated. PMID:28780566

The main component of paint thinner used in industry is toluene diisocyanate (TDI) which can cause occupational asthma in 5-10% of exposed workers. To investigate the effect of TDI on 99mTc clearance rate of alveolar epithelium and on pulmonary function tests (PFT) in automobile painters, and to determine the relationship between 99mTc-DTPA radioaerosol lung scintigraphy and serum levels of antioxidant enzymes and metalloproteinases (MMPs) of automobile painters. Twenty-eight automobile painters and 13 control subjects were included in the study. 99mTc-DTPA aerosol inhalation scintigraphy and PFT were administered to all subjects. Clearance half-time (T1/2) and penetration index (PI) on the first-minute image after 99mTc-DTPA scintigraphy were calculated. Blood levels of MDA, antioxidant enzymes and metalloproteinases were measured. The mean T1/2 values of automobile painters were longer in both smoker and non-smoker subjects, but the difference was not significant (P>0.05). Although the PFT values decreased in automobile painters, there was no significant difference between each group. Any correlation between spirometric measurements and T1/2 or PI values in non-smoking automobile painters was not detected. Negative correlation among mean T1/2 value and FVC% and FEV1% in smoking automobile painters, and positive correlation between mean T1/2 value and MMP-9, GSH-Px levels in non-smoking automobile painters were detected. Our results suggested that the clearance of 99mTc-DTPA from the lungs of automobile painters was slower than in the control group, but the difference is not statistically significant. This data also supports the observation that TDI occasionally stimulates bronchial changes rather than alveolar changes in automobile painters.

The 1916 painters and the 1948 electricians who resided in the Canton of Geneva at the time of the 1970 census were identified and followed up to 1984. During the study period 121 disability pensions were awarded to painters and 59 to electricians. Age standardised incidence of disability per 1000 man-years at risk was higher among painters than among electricians for all neuropsychiatric causes (1.23/1000 and 0.68/1000, respectively) and for all other causes (5.50/1000 and 3.41/1000, respectively). No case of presenile dementia was diagnosed among painters. There was inadequate evidence to indicate that the higher risk of neuropsychiatric disability for painters might have been due to their occupational exposure to organic solvents. A possible toxic effect of these substances on the central nervous system was confounded with alcoholism which was associated with disability from neuropsychiatric disease in 12 of 20 painters and in only one of 10 electricians. Mortality and incidence of cancer were assessed among both cohorts and compared with the expected figures calculated from Geneva rates. Among painters there was a significant increase in overall mortality (O = 254, E = 218.5), in mortality from all cancers (O = 96, E = 75.4), and in incidence from all cancers (O = 159, E = 132.0). For the specific cancer sites, there was a significant excess risk for lung cancer (mortality: O = 40, E = 23.0), which was possibly related to occupational exposure to asbestos and to zinc chromate, although cigarette smoking was not controlled. The significant excesses of biliary tract cancer and of bladder cancer were in accordance with previous observations among painters from other countries. There was also a significant increase in incidence from testicular cancer (O=5, E=1.6), which has not been reported before. For causes of death other than cancer the excesses for alcoholism (O=5, E=0.8). for liver cirrhosis (O=14, E=8.8), for motor vehicle accidents (O=12, E=5.9), and for

Renaissance architecture for Ground Data Systems

1994-01-01

The Mission Operations and Data Systems Directorate (MO&DSD) has embarked on a new approach for developing and operating Ground Data Systems (GDS) for flight mission support. This approach is driven by the goals of minimizing cost and maximizing customer satisfaction. Achievement of these goals is realized through the use of a standard set of capabilities which can be modified to meet specific user needs. This approach, which is called the Renaissance architecture, stresses the engineering of integrated systems, based upon workstation/local area network (LAN)/fileserver technology and reusable hardware and software components called 'building blocks.' These building blocks are integrated with mission specific capabilities to build the GDS for each individual mission. The building block approach is key to the reduction of development costs and schedules. Also, the Renaissance approach allows the integration of GDS functions that were previously provided via separate multi-mission facilities. With the Renaissance architecture, the GDS can be developed by the MO&DSD or all, or part, of the GDS can be operated by the user at their facility. Flexibility in operation configuration allows both selection of a cost-effective operations approach and the capability for customizing operations to user needs. Thus the focus of the MO&DSD is shifted from operating systems that we have built to building systems and, optionally, operations as separate services. Renaissance is actually a continuous process. Both the building blocks and the system architecture will evolve as user needs and technology change. Providing GDS on a per user basis enables this continuous refinement of the development process and product and allows the MO&DSD to remain a customer-focused organization. This paper will present the activities and results of the MO&DSD initial efforts toward the establishment of the Renaissance approach for the development of GDS, with a particular focus on both the technical

Occupational exposure as a painter is associated with DNA damage and development of cancer. Comet assay has been widely adopted as a sensitive and quantitative tool for DNA damage assessment at the individual cell level in populations exposed to genotoxics. The aim of this study was to assess the application of the high-throughput comet assay, to determine the DNA damage in car spray painters. The study population included 52 car spray painters and 52 unexposed subjects. A significant increase in the %TDNA median (p <  0.001) was observed in the exposed group in comparison to the unexposed group. Neither age (%TDNA: p =  0.913) nor time of exposure (%TDNA: p = 0.398) were significantly correlated with DNA damage. The car spray painters who consumed alcohol did not show a significant increase in DNA damage compared to nonalcohol consumers (p  > 0.05). The results showed an increase in DNA breaks in car spray painters exposed to organic solvents and paints; furthermore, they demonstrated the application of high-throughput comet assay in an occupational exposure study to genotoxic agents.

The Universities of the Renaissance and Reformation.

European universities had great intellectual and religious influence in the Renaissance and Reformation and exhibited considerable variety. Italian universities taught law and medicine to doctoral students. Their loose organization made it possible for professors to produce original research in law, medicine, philosophy, and the humanities. Northern European universities concentrated on teaching arts to undergraduates, while theology was the most important graduate faculty. Their stronger structure enabled Martin Luther and other professors of theology in German, Dutch, Swiss, and English universities to create and lead the Protestant. By the early seventeenth century universities everywhere were in decline.

Effect of reduced use of organic solvents on disability pension in painters.

PubMed

Järvholm, Bengt; Burdorf, Alex

2017-11-01

To investigate whether the decreased use of paints based on organic solvents has caused a decreased risk for neuropsychiatric disorders in painters by studying their incidence in disability pensions. The incidence of disability pension in Swedish painters who had participated in health examinations between 1971 and 1993 was studied through linkage with Swedish registers of disability pension over 1971-2010 and compared with the incidence in other construction workers as woodworkers, concrete workers and platers. When phasing out began in the 1970s, about 40% of paints were based on organic solvents and it had decreased to 4% in 1990s. The analysis was adjusted for age, time period, body mass index and smoking. The painters (n=23 065) had an increased risk of disability pension due to neurological diagnosis (n=285, relative risk (RR) 1.92, 95% CI 1.67 to 2.20) and psychiatric diagnosis (n=632, RR=1.61, 95 % CI 1.42 to 1.82). For neurological disorders there was a time trend with a continuously decreasing risk from 1980 onwards, but there was no such trend for psychiatric disorders. High exposure to organic solvents increased the risk for disability pension in neurological disorders, and the risk decreased when the use of organic solvents decreased. The painters also had an increased risk of disability pension due to psychiatric disorders, but the causes have to be further investigated. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Adverse effects attributed to exposure to paints are currently a concern because of the continued widespread use of paint containing trace elements. Thus, occupational survey amongst painters in Lagos and determination of trace elements and oxidative stress parameters were carried out. Descriptive cross-sectional survey was done using a standardized questionnaire to obtain job safety-related information. Forty-eight percent of the painters were aware of hazards associated with painting and 52 % of these workers were aware of the necessary precautionary measures during painting. There were no significant differences (p ≥ 0.05) between the levels of trace elements in the blood of painters and the control subjects. However, there was a significance increase (p ≤ 0.0001) in the level of malondialdehyde and a decrease (p ≤ 0.001) in the levels of reduced glutathione, superoxide dismutase, and catalase of the painters compared to the control. An increase in oxidative stress parameters may not only be due to trace element concentrations, but also the painters' exposure to some petrochemical solvents during mixing of paints.

Thyroid swellings in the art of the Italian Renaissance.

PubMed

Sterpetti, Antonio V; De Toma, Giorgio; De Cesare, Alessandro

2015-09-01

Thyroid swellings in the art of the Italian Renaissance are sporadically reported in the medical literature. Six hundred paintings and sculptures from the Italian Renaissance, randomly selected, were analyzed to determine the prevalence of personages with thyroid swellings and its meaning. The prevalence of personages with thyroid swellings in the art of Italian Renaissance is much higher than previously thought. This phenomenon was probably secondary to iodine deficiency. The presence of personages with thyroid swelling was related to specific meanings the artists wanted to show in their works. Even if the function and the role of the thyroid were discovered only after thyroidectomy was started to be performed, at the beginning of the 19th century, artists of the Italian Renaissance had the intuition that thyroid swellings were related to specific psychological conditions. Artistic intuition and sensibility often comes before scientific demonstration, and it should be a guide for science development. Copyright © 2015 Elsevier Inc. All rights reserved.

1988-01-01

To determine whether 2-ethoxyethanol (2-EE) and 2-methoxyethanol (2-ME) affected the reproductive potential of exposed men, we examined the semen of 73 painters and 40 controls who work in a large shipyard. An industrial hygiene survey was performed to characterize the work environment. The men supplied information on demographic characteristics, medical conditions, personal habits, and reproductive history; underwent a physical examination; and provided a semen sample. Semen samples were analyzed for pH, volume, turbidity, liquidity, viability by stain exclusion and hypo-osmotic stress, sperm density and count per ejaculate, motility using a videotape technique, morphology, and morphometry. Serum was analyzed for testosterone, FSH, and LH. The industrial hygiene survey revealed that the painters were exposed to 2-EE at a time-weighted average (TWA) of 0-80.5 mg/m3 with a mean of 9.9 mg/m3, and to 2-ME at a TWA of 0-17.7 mg/m3 with a mean of 2.6 mg/m3. Painters had an increased prevalence of oligospermia and azoospermia and an increased odds ratio for a lower sperm count per ejaculate, while smoking was controlled. This finding is consistent with prior animal studies and with one human study. Potential biases and confounding of the data are discussed.

Personal Exposure, Behavior, and Work Site Conditions as Determinants of Blood Lead Among Bridge Painters

Rodrigues, Ema G.; Virji, M. Abbas; McClean, Michael D.; Weinberg, Janice; Woskie, Susan; Pepper, Lewis D.

2009-01-01

Bridge painters are exposed to lead during several job tasks performed during the workday, such as sanding, scraping, and blasting. After the Occupational Safety and Health Administration standard was passed in 1993 to control lead exposures among construction workers including bridge painters, this study was conducted among 84 bridge painters in the New England area to determine the significant predictors of blood lead levels. Lead was measured in personal air and hand wipe samples that were collected during the 2-week study period and in blood samples that were collected at the beginning and at the end of the study period. The personal air and hand wipe data as well as personal behaviors (i.e., smoking, washing, wearing a respirator) and work site conditions were analyzed as potential determinants of blood lead levels using linear mixed effects models. Our results show that the mean air lead levels over the 2-week period were the most predictive exposure measure of blood lead levels. Other individual-level significant predictors of blood lead levels included months worked on bridge painting crews, education, and personal hygiene index. Of the site-level variables investigated, having a containment facility on site was a significant predictor of blood lead levels. Our results also indicate that hand wipe lead levels were significantly associated with higher blood lead levels at the end of the study period compared with the beginning of the study period. Similarly, smoking on site and respirator fit testing were significantly associated with higher blood lead levels at the end of the study period. This study shows that several individual-level and site-level factors are associated with blood lead levels among bridge painters, including lead exposure through inhalation and possible hand-to-mouth contact, personal behaviors such as smoking on site, respirator fit testing, and work site conditions such as the use of better containment facilities. Accordingly

The occurrence of phi in dento-facial beauty of fine art from antiquity through the Renaissance.

PubMed

Wiener, R Constance; Wiener Pla, Regina M

2012-01-01

External beauty is a complex construct that influences lives and may be impacted by dentists. Beauty is not easily quantified, but one cited anthropometric of beauty is the ratio phi, the number 1.618033(...). This study examined phi as a measure of female frontal facial beauty in classic Western art, using pre- Renaissance (N = 30), and Renaissance (N = 30) artwork. Four horizontal and five vertical ratios were determined in the works of art, which were then compared with the phi ratio. All horizontal ratios for both pre-Renaissance and Renaissance artwork were similar to each other, but did not contain the phi ratio (P < 0.001). Nevertheless, all vertical ratios for pre-Renaissance and Renaissance art-work did contain the phi ratio within their confidence intervals with the exception of the vertical ratio, "intereye point to soft tissue menton/ intereye point to stomion", that was found to be less than phi in the Renaissance group. The study provides evidence of the presence of the phi ratio in vertical aspect of females in artwork from pre-Renaissance through the Renaissance demonstrating consistent temporal preferences. Therefore, the phi ratio seems to be an important consideration in altering vertical facial dimensions in full mouth rehabilitation and reconstructive orthognathic surgery involving females.

Renaissance Neurosurgery: Italy's Iconic Contributions.

PubMed

Nanda, Anil; Khan, Imad Saeed; Apuzzo, Michael L

2016-03-01

Various changes in the sociopolitical milieu of Italy led to the increasing tolerance of the study of cadavers in the late Middle Ages. The efforts of Mondino de Liuzzi (1276-1326) and Guido da Vigevano (1280-1349) led to an explosion of cadaver-centric studies in centers such as Bologna, Florence, and Padua during the Renaissance period. Legendary scientists from this era, including Leonardo Da Vinci, Andreas Vesalius, Bartolomeo Eustachio, and Costanzo Varolio, furthered the study of neuroanatomy. The various texts produced during this period not only helped increase the understanding of neuroanatomy and neurophysiology but also led to the formalization of medical education. With increased understanding came new techniques to address various neurosurgical problems from skull fractures to severed peripheral nerves. The present study aims to review the major developments in Italy during the vibrant Renaissance period that led to major progress in the field of neurosurgery. Published by Elsevier Inc.

Several generations of Swedish children have become acquainted with the world of fairy-tales through illustrations by the painter John Bauer in the Christmas magazine Goblins and Trolls. Next to his portrayal of grotesque but humorous trolls, his paintings of the Moon and the starry sky are among those best remembered. These pictures have inspired very many Swedes to take pleasure in the beauty of the stars and the movement of the Moon.

Human reproduction in art: from myths to history.

Petraglia, Felice; Bettini, Maurizio

2010-08-01

Conception, gestation, and birth, including maternal-fetal health, have been the subject of narrative and art since early human history. Myth and histories related to pregnancy were represented by sculptors and painters as well as the subject of several operas: the mystery of reproduction was always a fascinating theme. This mystery was commonly represented across cultures and time, in the old world, from Egypt to India, to Greece and Rome continuing until the Renaissance and the Modern period. To be an artist meant also to be a scientist in several societies. The current paper reports 12 examples of the fusion of art and reproductive science.

Raman spectroscopic study of "The Malatesta": a Renaissance painting?

2015-02-25

Raman spectroscopic analysis of the pigments on an Italian painting described as a "Full Length Portrait of a Gentleman", known also as the "Malatesta", and attributed to the Renaissance period has established that these are consistent with the historical research provenance undertaken earlier. Evidence is found for the early 19th Century addition of chrome yellow to highlighted yellow ochre areas in comparison with a similar painting executed in 1801 by Sir Thomas Lawrence of John Kemble in the role of Hamlet, Prince of Denmark. The Raman data are novel in that no analytical studies have previously been made on this painting and reinforces the procedure whereby scientific analyses are accompanied by parallel historical research.

"Being the world eternal ..." the age of the Earth in Renaissance Italy.

PubMed

Dal Prete, Ivano

2014-06-01

Scholarship on the early modern period assumes that the Creation story of Genesis and its chronology were the only narratives openly available in Renaissance Europe. This essay revisits the topic by exploring a wide range of literature on the age and nature of the Earth in early modern Italy. It suggests that, contrary to received notions, in the early 1500s an Aristotelian ancient world characterized by slow geological change was a common assumption in discourse on the Earth. These notions were freely disseminated by popularizations and didactic literature in the vernacular, which made them available to a large readership. Counter-Reformation cultural policies eventually called for a tighter integration of theology and natural philosophy; however, the essay argues that even then the creation of the world was usually placed in a remote and undetermined past, not necessarily tied to the short timescales of contemporary chronology.

"Masculine love," Renaissance writing, and the "new invention" of homosexuality: an addendum.

PubMed

Forker, C R

1996-01-01

Joseph Cady's recent article, "Masculine Love," Renaissance Writing, and the "New Invention' of Homosexuality," Journal of Homosexuality 23.1-2 (1992): 9-40, did much to shed new light on the controversial issue of whether homosexual identity is a relatively late phenomenon (late seventeenth- or early eighteenth-century at the earliest according to scholars of the "constructivist" persuasion) or already existed in the age of the Renaissance and before. Cady argues that homosexual identity is at least as old as the Elizabethan age, and cites from widely divergent sources several early modern instances of the term "masculine love," a term that seems to have been used exclusively to refer to the sexual preference of men for members of their own gender. The present note adds a further example to buttress Cady's case-namely the term "masculine conversation" from Arthur Wilson's History of Great Britain (1653), an account of the reign of James I (who was widely recognized to be sexually attracted to men). The term "conversation" often referred to sexual intercourse, being used in legal discourse to define adultery, and therefore constitutes an even more explicit example of denotative language than those Cady cites. Since Wilson discusses Sir Francis Bacon as well as James I, this brief article explores the historically documentable sexual preferences of these two figures in addition to that of the dramatist Christopher Marlowe and of Bacon's brother Anthony, a diplomat, all of whom seem to have been strongly oriented to "masculine love" and "masculine conversation".

2012-03-01

Painters reproduce the appearances they see, or visualize. The entire human visual system is the first part of that process, providing extensive spatial processing. Painters have used spatial techniques since the Renaissance to render HDR scenes. Silver halide photography responds to the light falling on single film pixels. Film can only mimic the retinal response of the cones at the start of the visual process. Film cannot mimic the spatial processing in humans. Digital image processing can. This talk studies three dramatic visual illusions and uses the spatial mechanisms found in human vision to interpret their appearances.

Ulisse Aldrovandi's Pandechion epistemonicon and the use of paper technology in Renaissance natural history.

PubMed

Kraemer, Fabian

2014-01-01

Reconstructing the formation and use of the hitherto neglected Pandechion epistemonicon, Ulisse Aldrovandi's (152-1605) extant manuscript encyclopaedia, this article shows that early modern naturalists in many ways shared a world of paper with the members of several other professions. An analysis of the Pandechion suggests that Renaissance naturalists who applied the humanist jack-of-all-trades, the commonplace book, in their own field sometimes considerably altered its form. Aldrovandi tested and recombined different techniques so as to arrive at the paper technology that he considered to be the most fit for his purposes. He thereby drew on administrative practices as well as on the bookkeeping practices of early modern merchants that he knew first-hand.

Optical or mechanical aids to drawing in the early Renaissance? A geometric analysis of the trellis work in Robert Campin's Mérode Altarpiece

NASA Astrophysics Data System (ADS)

Kulkarni, Ashutosh; Stork, David G.

2009-02-01

A recent theory claims that some Renaissance artists, as early as 1425, secretly traced optically projected images during the execution of some passages in some of their works, nearly a quarter millennium before historians of art and of optics have secure evidence anyone recorded an image this way. Key evidence adduced by the theory's proponents includes the trelliswork in the right panel of Robert Campin's Merode altarpiece triptych (c. 1425-28). If their claim were verified for this work, such a discovery would be extremely important to the history of art and of image making more generally: the Altarpiece would be the earliest surviving image believed to record the projected image of an illuminated object, the first step towards photography, over 400 years later. The projection theory proponents point to teeny "kinks" in the depicted slats of one orientation in the Altarpiece as evidence that Campin refocussed a projector twice and traced images of physically straight slats in his studio. However, the proponents rotated the digital images of each slat individually, rather than the full trelliswork as a whole, and thereby disrupted the relative alignment between the images of the kinks and thus confounded their analysis. We found that when properly rotated, the kinks line up nearly perfectly and are consistent with Campin using a subtly kinked straightedge repeatedly, once for each of the slats. Moreover, the proponents did not report any analysis of the other set of slats-the ones nearly perpendicular to the first set. These perpendicular slats are straight across the break line of the first set-an unlikely scenario in the optical explanation. Finally, whereas it would have been difficult for Campin to draw the middle portions of the slats perfectly straight by tracing a projected image, it would have been trivially simple had he used a straightedge. Our results and the lack of any contemporaneous documentary evidence for the projection technique imply that

Francis Bacon and the "Interpretation of Nature" in the late Renaissance.

PubMed

Serjeantson, Richard

2014-12-01

The "interpretation of nature" (interpretatio naturae) is the leading idea in Francis Bacon's natural philosophy. But by contrast with his ideas about method, induction, or experiment, the significance of the "interpretation of nature" has received very little scholarly attention. This essay tests the originality of Bacon's idea by means of a focused survey of existing forms of Renaissance natural knowledge-Aristotelian and anti-Aristotelian natural philosophy, Galenic and Paracelsian medicine, natural magic, physiognomy, natural history-before turning to consider the much more prominent place of "interpretation" in the fields of Renaissance logic, revealed and natural theology, and law. It finds that Bacon's application of the idea of "interpretation" to nature was highly original, but also that certain important aspects of his conception have analogies in Renaissance civil law. The essay concludes by exploring the implications of these findings for a recent body of scholarship in the history of the sciences that invokes the notion of the "interpretation of nature" to characterize pre-Baconian natural philosophy more generally.

2014-01-01

Objectives Sex differences in occupational biomechanical exposures may be part of the explanation why musculoskeletal complaints and disorders tend to be more common among women than among men. We aimed to determine possible sex differences in task distribution and task-specific postures and movements of the upper extremities among Danish house painters, and to establish sex-specific task exposure matrices. Methods To obtain task distributions, we sent out a questionnaire to all members of the Painters' Union in Denmark (N = 9364), of whom 53% responded. Respondents reported their task distributions in a typical week. To obtain task exposures, postures and movements were measured in 25 male and 25 female house painters for one whole working day per person. We used goniometers on the wrists, and inclinometers on the forehead and the upper arms. Participants filled in a logbook allowing task-specific exposures to be identified. Percentiles and % time with non-neutral postures were used to characterise postures. Velocity, range of motion, repetitiveness, and variation were used as measures of movement. Cochran-Mantel-Haenszel statistics and unpaired double-sided t-tests with post-hoc Bonferroni correction were used to evaluate sex differences. Results Statistically significant (p<0.05) sex differences were revealed in task proportions, but the proportions differed by less than 4%. For task exposures, no statistically significant sex differences were found. Conclusions Only minor sex differences were found in task distribution and task exposures regarding postures and movements among Danish house painters. Sex-specific task exposure matrices were established. PMID:25365301

Occupational asthma and contact dermatitis in a spray painter after introduction of an aziridine cross-linker.

PubMed Central

Leffler, C T; Milton, D K

1999-01-01

A 23-year-old spray painter developed contact dermatitis and respiratory difficulty characterized by small airways obstruction shortly after the polyfunctional aziridine cross-linker CX-100 began to be used in his workplace as a paint activator. The symptoms resolved after he was removed from the workplace and was treated with inhaled and topical steroids. Painters may have an increased risk of asthma due to exposure to a variety of agents, such as isocyanates, alkyd resins, and chromates. This case illustrates the importance of using appropriate work practices and personal protective equipment to minimize exposure. Occupational asthma is diagnosed by a history of work-related symptoms and exposure to known causative agents. The diagnosis is confirmed by serial pulmonary function testing or inhalational challenge testing. The risk of asthma attributable to occupational exposures is probably underappreciated due to underreporting and to inappropriate use of narrow definitions of exposure in epidemiologic studies of attributable risk.

Fashion, time and the consumption of a Renaissance man in Germany: the costume book of Matthaus Schwarz of Augsburg, 1496-1564.

PubMed

Mentges, Gabriele

2002-01-01

This article uses the perspective of cultural anthropology to consider the construction of an early modern perception of time and its relation to the dress and personal consumption of a male subject. It focuses on a costume book from the Renaissance compiled by Matthäus Schwarz, a member of the bourgeoisie, who lived in Augsburg from 1496 to 1574. The book contains a collection of 137 drawings, portraying Schwarz's personal choice of dress. It is also an account of Schwarz's life, beginning with his parents, then covering his life-stages from birth to old age. The relationships between body and dress and between the male subject and the world run as a major thread through the book. This article shows how closely connected Schwarz's body is with the life of commodities (dress) and consumption. The life-story of this Renaissance man is expressed in terms of changing fashions, which act as his subjective measure of time.

Gout in Duke Federico of Montefeltro (1422-1482): a new pearl of the Italian Renaissance.

Fornaciari, Antonio; Giuffra, Valentina; Armocida, Emanuele; Caramella, Davide; Rühli, Frank J; Galassi, Francesco Maria

2018-01-01

The article examines the truthfulness of historical accounts claiming that Renaissance Duke Federico of Montefeltro (1422-1482) suffered from gout. By direct paleopathological assessment of the skeletal remains and by the philological investigation of historical and documental sources, primarily a 1461 handwritten letter by the Duke himself to his personal physician, a description of the symptoms and Renaissance therapy is offered and a final diagnosis of gout is formulated. The Duke's handwritten letter offers a rare testimony of ancient clinical self-diagnostics and Renaissance living-experience of gout. Moreover, the article also shows how an alliance between historical, documental and paleopathological methods can greatly increase the precision of retrospective diagnoses, thus helping to shed clearer light onto the antiquity and evolution of diseases.

Our unacknowledged ancestors: dream theorists of antiquity, the middle ages, and the renaissance.

PubMed

Rupprecht, C S

1990-06-01

Exploring the dream world from a modern, or post-modern, perspective, especially through the lens of contemporary technologies, often leads us as researchers to see ourselves as engaged in a new and revolutionary discourse. In fact, this self-image is a profoundly ahistorical one, because it ignores the contributions of ancient, medieval and Renaissance oneirologists who wrote extensively, albeit in different terms and images of lucidity, prerecognition, day residue, wish fulfillment, incubation, problem solving, REM, obe, and the collective unconscious. There are also analogues in these early accounts to anxiety, recurrent, mirror, telepathic, shared, flying, and death dreams. Dream interpretation through music, analysis of dream as narrative, sophisticated theories about memory and language and symbolization are all part of the tradition. Further, early texts pose many issues in sleep and dream research which are not currently being pursued. We dream workers of the late twentieth century should therefore fortify ourselves with knowledge of the oneiric past as one important way to enhance our dream work in the twenty-first century.

2005-11-01

Many myths, theories, and speculations exist as to the exact etiology of the diseases, drugs, and chemicals that affected the creativity and productivity of famous sculptors, classic painters, classic music composers, and authors. To emphasize the importance of a modern clinical chemistry laboratory and hematology coagulation laboratory in interpreting the basis for the creativity and productivity of various artists. This investigation analyzed the lives of famous artists, including classical sculptor Benvenuto Cellini; classical sculptor and painter Michelangelo Buonarroti; classic painters Ivar Arosenius, Edvard Munch, and Vincent Van Gogh; classic music composer Louis Hector Berlioz; and English essayist Thomas De Quincey. The analysis includes their illnesses, their famous artistic works, and the modern clinical chemistry, toxicology, and hematology coagulation tests that would have been important in the diagnosis and treatment of their diseases. The associations between illness and art may be close and many because of both the actual physical limitations of the artists and their mental adaptation to disease. Although they were ill, many continued to be productive. If modern clinical chemistry, toxicology, and hematology coagulation laboratories had existed during the lifetimes of these various well-known individuals, clinical laboratories might have unraveled the mysteries of their afflictions. The illnesses these people endured probably could have been ascertained and perhaps treated. Diseases, drugs, and chemicals may have influenced their creativity and productivity.

Painters of automobiles are exposed to pure and mixed solvents that have been associated with neurological effects and carcinogenic mutations. To characterize the health and work conditions of individuals who are occupationally exposed to organic solvents used in sheet metal and auto body shops in Bogota. Descriptive, cross-sectional study that characterizes the health and work conditions of individuals exposed to organic solvents in sheet metal and auto body shops in Bogota. A group exposed to the solvents was compared to an unexposed group. Air concentrations of benzene, toluene and xylene (BTX) were determined, individual questionnaires were administered and phenylmercapturic, hippuric and ortho- and para-methylhippuric acids were measured in urine. The results of the measurements and the questionnaires were correlated to determine the exposure panorama. For the three BTX metabolites, statistically significant differences (p<0.001) were found between the population exposed to the solvents and the unexposed population. For the exposed population, positive correlations were found between toluene in air and hippuric acid in urine (rho=0.82) and between xylene in air and o-methylhippuric acid in urine (rho=0.76). Hippuric acid values exceeded permissible levels in 11 workers and p-methylhippuric acid exceeded permissible levels in 8 workers. None of the phenylmercapturic values exceeded the limit. Auto painters are exposed to high levels of organic solvents at the workplace and do not have adequate industrial health and safety conditions to perform their jobs.

From Renaissance art to contemporary electron microscopy: DeGroft's rediscovery of Titian's "lost" portrait of Federico II Gonzaga, Duke of Mantua, of 1539-40.

2002-01-01

At the Ultrapath X meeting in Florence, the regular session opened with a presentation of Aaron DeGroft's engrossing story of investigating the authenticity of a portrait of Federico II Gonzaga, Duke of Mantua. In the early 1900s, this work had been deemed to be an authentic production by Titian, a great artist of the Italian Renaissance. A respected art historian, however, discovered a conflict of dates that led to the conclusion that this work was not authentic. In a process sometimes analogous to the practice of surgical pathology, Dr. DeGroft pursued a review of the original materials that refutes this seeming contradiction of dates. Dr. DeGroft also undertook an extensive art historical examination and scientific analysis, including the use of electron microscopy, to persuasively conclude that this portrait is authentic. Further, his work provided a bridge from the conference setting in Florence, rich in Renaissance art, to the contemporary update on ultrastructural pathology provided by the conference.

Renaissance mummies in Italy.

Fornaciari, G

1999-01-01

The paleopathological study of 40 Italian Renaissance mummies has allowed us to perform about 20 diagnoses, of which 5 concern infectious (smallpox, hepatitis, condyloma, syphilis and pneumonia), 4 metabolic (obesity, atherosclerosis, gallstones and uric acid nephrolithiasis), 2 articular (DISH and rheumatoid arthritis) and 2 neoplastic (skin apithelioma and colon adenocarcinoma) diseases. The mummy of an anonymous child, dated back to the 16th century (C14=1569 +/- 60), presented a diffuse vesiculo-pustular exanthema. Macroscopic aspects and regional distribution suggested smallpox, while EM reavealed many egg-shaped, virus-like particles (250 x 50 nm), with a central dense core. Following incubation with anti-smallpox virus antiserum and protein A-gold complex immunostaining, the particles resulted completely covered with protein A-gold. These results clearly show that this Neapolitan child died of a severe form of smallpox some four centuries ago. The mummy of Maria of Aragon, Marquise of Vasto (1503-1568), reavealed on the left arm an oval, cutaneous ulcer (15x10 nm) with linen dressing. Indirect immunofluorescence with anti-treponema pallidum antibody identified a large number of filaments with the morphological characteristics of fluorescent treponemes. EM evidenced typical spirochetes, with axial fibril. These findings clearly demonstrate a treponemal, probably venereal, infection. The mummy of Ferrante I of Aragon, King of Naples (1431-1494), revealed an adenocarcinoma extensively infiltrating the muscles of the small pelvis. A molecular study of the neoplastic tissue evidenced a typical mutation of the K-ras gene codon 12:the normal sequence GGT (glycine) was altered into GAT (aspartic acid). At present this genetic change is the most frequent mutation of the K-ras gene in sporadic colorectal cancer. The alimentary "environment" of the Neapolitan court of the XV century, with its abundance of natural alimentary alkylating agents, well explains this

Malignant Fibrous Histiocytoma of the Maxillary Sinus in a Spray Painter from an Automobile Repair Shop

PubMed Central

2013-01-01

Background We report a case of a spray painter who developed malignant fibrous histiocytoma (MFH) of the maxillary sinus following long-term exposure to chromium, nickel, and formaldehyde, implying that these agents are probable causal agents of MFH. Case report The patient developed right-sided prosopalgia that began twenty months ago. The symptom persisted despite medical treatment. After two months, he was diagnosed with MFH through imaging studies, surgery, and pathological microscopic findings at a university hospital in Seoul. His social, medical, and family history was unremarkable. The patient had worked for about 18 years at an automobile repair shop as a spray painter. During this period, he had been exposed to various occupational agents, such as hexavalent chromium, nickel, and formaldehyde, without appropriate personal protective equipment. He painted 6 days a week and worked for about 8 hours a day. Investigation of the patient’s work environment detected hexavalent chromium, chromate, nickel, and formaldehyde. Conclusions The study revealed that the patient had been exposed to hexavalent chromium, formaldehyde, and nickel compounds through sanding and spray painting. The association between paranasal cancer and exposure to the aforementioned occupational human carcinogens has been established. We suggest, in this case, the possibility that the paint spraying acted as a causal agent for paranasal cancer. PMID:24472378

Significant findings concerning the production of Italian Renaissance lustred majolica

NASA Astrophysics Data System (ADS)

Padeletti, G.; Fermo, P.

2013-12-01

In the present paper the main results obtained, over a period of more than ten years, from a series of studies concerning the characterization of Italian Renaissance lustred majolicas (from Gubbio and Deruta, Umbria, Italy) are presented. Lustre decoration is a well-known technique, consisting in the application of a thin metallic iridescent film, containing silver and copper nanoparticles, over a previously glazed ceramic object. The technique had its origin in Persia (IX century), was imported by Moorish in Spain, and then developed in central Italy during the Renaissance period. Numerous analytical techniques (among which, ETASS, XRD, UV-Vis, SEM-EDX) have been employed for the characterization of lustred ceramic shards, allowing one to acquire information on both lustre chemical composition and nanostructure. In this way it was shown how some technological parameters, such as the firing conditions, are mandatory to obtain the final result. The presence of a specific marker of the lustre Italian production, i.e., cosalite (Pb2Bi2S5), has been also highlighted. From the study of the ceramic body composition (by means of XRD and ICP-OES and in particular of chemometric techniques) acquired on more than 50 ceramic shards it was possible to discriminate between Deruta and Gubbio production, in this way allowing one to assign objects of uncertain provenance to a specific site. Finally, the most interesting results obtained studying excellent lustred masterpieces from Renaissance belonging to important museums are here presented. In particular, with the use of nondestructive techniques (PIXE, RBS, and portable XRD), the production of Mastro Giorgio Andreoli from Gubbio was investigated. By means of the same analytical approach, one of the first examples of lustre in Italy (the famous Baglioni's albarello) was examined, and the controversial question of its attribution to Italian production was scientifically faced.

An abbreviated history of the ear: from Renaissance to present.

PubMed Central

Hachmeister, Jorge E.

2003-01-01

In this article we discuss important discoveries in relation to the anatomy and physiology of the ear from Renaissance to present. Before the Renaissance, there was a paucity of knowledge of the anatomy of the ear, because of the relative inaccessibility of the temporal bone and the general perception that human dissections should not be conducted. It was not until the sixteenth century that the middle ear was described with detail. Further progress would be made between the sixteenth and eighteenth century in describing the inner ear. In the nineteenth century, technological advancement permitted a description of the cells and structures that constitute the cochlea. Von Helmholtz made further progress in hearing physiology when he postulated his resonance theory and later von Békésy when he observed a traveling wave in human cadavers within the cochlea. Brownell later made a major advance when he discovered that the ear has a mechanism for sound amplification, via outer hair cell electromotility. Images Figure 1 Figure 2 PMID:15369636

Effects of Personal Protective Equipment Use and Good Workplace Hygiene on Symptoms of Neurotoxicity in Solvent-Exposed Vehicle Spray Painters.

2018-03-12

To assess the association between the use of personal protective equipment (PPE) and good workplace hygiene and symptoms of neurotoxicity in solvent-exposed vehicle spray painters. Exposure control measures including PPE-use and workplace hygiene practices and symptoms of neurotoxicity were assessed in 267 vehicle repair spray painters. Symptoms were assessed using an adapted version of the EUROQUEST Questionnaire. Frequent respirator and glove use was inversely and significantly associated with symptoms of neurotoxicity in a dose-dependent manner (P < 0.05 for trend) with the strongest protective effect found for consistent glove use (odds ratios [OR] 0.1-0.2, P < 0.01, for reporting ≥10 and ≥5 symptoms). A clear dose-response trend was also observed when combining frequency of respirator and glove use (P < 0.05 for reporting ≥5 and ≥10 symptoms), with an overall reduction in risk of 90% (OR, 0.1, P < 0.01) for those who consistently used both types of PPE. Protective effects were most pronounced for the symptom domains of psychosomatic (P < 0.05 for trend, for combined PPE use), mood (P < 0.05), and memory and concentration symptoms combined (P < 0.05), with reductions in risk of >80%. Poor hygiene workplace practices, such as solvent exposure to multiple body parts (OR 3.4, P = 0.11 for reporting ≥10 symptoms), were associated with an increased risk of symptoms. When using a general workplace hygiene score derived from a combination of PPE-use and (good) workplace practice factors an inverse and significant dose-response trend was observed for reporting ≥5 (P < 0.01) and ≥10 symptoms (P < 0.01). This study has shown that PPE-use and good workplace hygiene are associated with a strongly reduced risk of symptoms of neurotoxicity in solvent-exposed vehicle spray painters.

Renaissance painters used a number of inorganic color materials. The development of mineralogy as a discipline opened a new discourse on mineral pigments. Agricola and other naturalists were familiar with the contemporary writings on art technology, but their focus was different. Therefore, the exchange of knowledge between these two color worlds remained selective. One possible meeting point was the Kunstkammer where the study of natural objects and materials was combined with an interest in the manual execution of a painting.

The role of images in the development of Renaissance natural history.

PubMed

Kusukawa, Sachiko

2011-01-01

This review surveys recent scholarship on the history of natural history with special attention to the role of images in the Renaissance. It discusses how classicism, collecting and printing were important catalysts for the Renaissance study of nature. Classicism provided inspiration of how to study and what kind of object to examine in nature, and several images from the period can be shown to reflect these classical values. The development of the passion for collecting and the rise of commerce in nature's commodities led to the circulation of a large number of exotic flora and fauna. Pictures enabled scholars to access unobtainable objects, build up knowledge of rare objects over time, and study them long after the live specimens had died away. Printing replicated pictures alongside texts and enabled scholars to share and accumulate knowledge. Images, alongside objects and text, were an important means of studying nature. Naturalists' images, in turn, became part of a larger visual culture in which nature was regarded as a beautiful and fascinating object of admiration.

These are a 16th century Hat Badge of Adam and Eve, a 19th century Fortitude Pendant and a Diana Pendant presumed to be of the 16th century (The Walters Art Gallery, Jewelry, Ancient to Modern (Viking, New York, 1979)), Ref. [1]. PIXE spectroscopy was applied to examine the elemental composition of the gold and of the enamels. Compositional differences, including the use of post-Renaissance colorants, were found between the enamels in separate regions of each of the three pieces. The modern colorant, chromium, was, in fact, found in all of the pieces and uranium was found in only the Diana Pendant. There are some differences in the gold purity of the three objects; there are significant differences in the solders used even within one object, the Fortitude Pendant.

Spanish renaissance urology is a heirloom from both islamic and scholastic medieval trends. Theory and practice of urology generates three types of professionals: doctors, who study at universities and obtain their licence by making a demonstration before the Protomedicato Tribunal; surgeons, who acquire their surgical techniques through a teacher-pupil training relationship outside universities; and empirics, who were in charge of performing surgical operations. Urology literature exhibits greater interest during the second half of the century. Most outstanding are the works of Francisco Díaz. The pathologies arising greater interest are lithiasis and carnosities. Lithiasis is handled by lithotomists through a carving process of which there were two modalities, castilian and italian. Carnosities, which differential diagnosis, as well as that of lithiasis, was outlined by Andrés Laguna, are treated using a dilating bougie or, surgically, with a sharp instrument analogous to the urethrotome devised by Francisco Díaz.

Is it time for a nuclear energy renaissance? Among other things, nuclear power is a carbon neutral source of base load power. With the growth in energy use expected over the next 20 years and the growing negative impacts of global climate changes, the cost of oil and gas, energy security and diversity concerns, and progress on advanced reactor designs, it may be the right time for nuclear power to enter a new age of growth. Asia and Russia are both planning for a nuclear renaissance. In Europe, Finland and France have both taken steps to pursue new nuclear reactors.more » U.S. utilities are preparing for orders of new reactors; one submitted a request to the U.S. Nuclear Regulatory Commission (NRC) to review its request to construct a new reactor on an existing site. What has the industry been doing since nuclear energy was birthed in the 1960s? In those days a bold new industry boasted that nuclear power in the United States was going to be “too cheap to meter”, but as we all know this did not come about for many reasons. Eventually, it became clear that industry had neglected to do its homework. Critiques of the industry were made on safety, security, environment, economic competitiveness (without government support), and nonproliferation. All of these factors need to be effectively addressed to promote the confidence and support of the public – without which a nuclear power program is not feasible.« less

Selfie-photography is generally thought of as a cultural mass phenomenon of the early 21st century, inseparably related to the development and triumph of the smartphone with integrated camera. Western culture, however, has been highly familiar with self-depictions since the Renaissance days. Putting the contemporary selfie into this historic context covering more than five centuries of cultural development from Dürer's (1500) famous "Self-Portrait at 28" (also known as "Selbstbildnis im Pelzrock") to today's Instagram galleries allows for identifying central parallels concerning the technical and social antecedents as well as common underlying psychological factors and shared properties of different kinds of self-depiction. The article provides an overview of the types of contemporary photographic selfies and compares them with painted self-portraits. Finally, this historic perspective leads us to the insight that self-portraits as well as selfies are both referring to nothing less than the "conditio humana."

2004-04-01

A system for advanced fluorescence investigation of works of art has been assembled and integrated in a characterization procedure that allows one to localize and identify organic compounds that are present in artworks. At the beginning of the investigation, fluorescence lifetime imaging and spectroscopy address a selective microsampling of the artwork. Then analytical measurements of microsamples identify the chemical composition of the materials under investigation. Finally, on the basis of fluorescence lifetime and amplitude maps, analytical data are extended to the whole artwork. In such a way, information on the spatial distribution of organic materials can be inferred. These concepts have been successfully applied in an extensive campaign for analysis of Renaissance fresco paintings in Castiglione Olona, Italy. Residue of various types of glue and stucco left from a restoration carried out in the early 1970s was localized and classified. Insight into the technique used by the painter to make gilded reliefs was also obtained.

What Renaissance Literary Theory Tells us about Climate Communication

Guenther, G. J.

2017-12-01

Many current debates in climate communication-to convey the consensus or not to convey the consensus; to frighten people or encourage them-seem to center on the question of how to discuss climate science and its ability to predict climate impacts. By examining the Renaissance literary theory that represents poets as better teachers than philosophers and scientists, this paper argues that climate advocates should redefine climate communication to include a variety of artistic discourses that make meaning in order to inspire people into political action.

The Nuclear Renaissance — Implications on Quantitative Nondestructive Evaluations

Matzie, Regis A.

2007-03-01

The world demand for energy is growing rapidly, particularly in developing countries that are trying to raise the standard of living for billions of people, many of whom do not even have access to electricity. With this increased energy demand and the high and volatile price of fossil fuels, nuclear energy is experiencing resurgence. This so-called nuclear renaissance is broad based, reaching across Asia, the United States, Europe, as well as selected countries in Africa and South America. Some countries, such as Italy, that have actually turned away from nuclear energy are reconsidering the advisability of this design. This renaissance provides the opportunity to deploy more advanced reactor designs that are operating today, with improved safety, economy, and operations. In this keynote address, I will briefly present three such advanced reactor designs in whose development Westinghouse is participating. These designs include the advanced passive PWR, AP1000, which recently received design certification for the US Nuclear Regulatory Commission; the Pebble Bed Modular reactor (PBMR) which is being demonstrated in South Africa; and the International Reactor Innovative and Secure (IRIS), which was showcased in the US Department of Energy's recently announced Global Nuclear Energy Partnership (GNEP), program. The salient features of these designs that impact future requirements on quantitative nondestructive evaluations will be discussed. Such features as reactor vessel materials, operating temperature regimes, and new geometric configurations will be described, and mention will be made of the impact on quantitative nondestructive evaluation (NDE) approaches.

To study inhalation and dermal exposure to hexamethylene diisocyanate (HDI) and its oligomers as well as personal protection equipment (PPE) use during task performance in conjunction with urinary hexamethylene diamine (HDA) in car body repair shop workers and industrial spray painters. Personal task based inhalation samples (n = 95) were collected from six car body repair shops and five industrial painting companies using impingers with di-n-butylamine (DBA) in toluene. In parallel, dermal exposure was assessed using nitril rubber gloves. Gloves were submerged into DBA in toluene after sampling. Analysis for HDI and its oligomers was performed by LC-MS/MS. Urine samples were collected from 55 workers (n = 291) and analysed for HDA by GC-MS. Inhalation exposure was strongly associated with tasks during which aerosolisation occurs. Dermal exposure occurred during tasks that involve direct handling of paint. In car body repair shops associations were found between detectable dermal exposure and glove use (odds ratio (OR) 0.22, 95% confidence interval (CI) 0.09 to 0.57) and inhalation exposure level (OR 1.34, 95% CI 0.97 to 1.84 for a 10-fold increase). HDA in urine could be demonstrated in 36% and 10% of car body repair shop workers and industrial painting company workers respectively. In car body repair shops, the frequency of detectable HDA was significantly elevated at the end of the working day (OR 2.13, 95% CI 1.07 to 4.22 for 3-6 pm v 0-8 am). In both branches HDA was detected in urine of approximately 25% of the spray painters. In addition HDA was detected in urine of a large proportion of non-spray painters in car body repair shops. Although (spray) painting with lacquers containing isocyanate hardeners results in the highest external exposures to HDI and oligomers, workers that do not perform paint related tasks may also receive a considerable internal dose.

The interest in the physical perfection and the corporal forms brings as a result the creation of new anatomical studies. The anatomical knowledge progressed in the second half of the XV century, conceiving the knowledge of the human body as a basic reality of Medicine. One of the greater contributions of the Italian Universities to medicine was the teaching of anatomy. The Universities of Padua, Bologna, and Pisa educated in their classrooms great physicians like Andres Vesalio, Gabriel Fallopio, Realdo Colombo, Mondino de Luzzi, Julio Ceasar Aranzio, and Gaspare Tagliacozzi, among others. The teaching of anatomy during the Renaissance was characterized by the development of dissection techniques and autopsy practice, which was recognized as an extremely valuable skill for anatomical study. The dissections were made in circular amphitheatres in the following way: a Medicine professor read the text book, another one made the dissection, and a third one indicated the structures referred.

Artful imaging of the brain. From logo to metaphor, about Michelangelo and Kiefer.

Michelangelo has painted the fresco 'Creation of Adam' for the Sistine Chapel. Recently it was discovered that he had an outline of the brain concealed in Gods cloud. As a renaissance artist he was not supposed to believe that the brain is the seat of the soul. Only when the concept of structure and function of the central nervous system had developed, artistic presentation of the brain did become possible. The conceptual painter Kiefer, who is possessed by Germany's recent and past history, expressed his apprehension using the philosopher Heidegger and his writings as symbol and a naked brain as metaphor.

Leonardo da Vinci (April 15, 1452 to May 2, 1519) was an Italian Renaissance architect, musician, anatomist, inventor, engineer, sculptor, geometer, and painter. It has been gleaned from the many available historical documents that da Vinci was a vegetarian who respected and loved animals, and that he suffered from right hemiparesis in the last 5 years of his life. A vegetarian diet has both positive and negative influences on the cerebrovascular system. In this report, a possible relation between a vegetarian diet and stroke is discussed from various perspectives as related to Leonardo da Vinci's stroke. Copyright (c) 2010 S. Karger AG, Basel.

Bioprospecting the African Renaissance: The new value of muthi in South Africa

PubMed Central

Reihling, Hanspeter CW

2008-01-01

This article gives an overview of anthropological research on bioprospecting in general and of available literature related to bioprospecting particularly in South Africa. It points out how new insights on value regimes concerning plant-based medicines may be gained through further research and is meant to contribute to a critical discussion about the ethics of Access and Benefit Sharing (ABS). In South Africa, traditional healers, plant gatherers, petty traders, researchers and private investors are assembled around the issues of standardization and commercialization of knowledge about plants. This coincides with a nation-building project which promotes the revitalization of local knowledge within the so called African Renaissance. A social science analysis of the transformation of so called Traditional Medicine (TM) may shed light onto this renaissance by tracing social arenas in which different regimes of value are brought into conflict. When medicinal plants turn into assets in a national and global economy, they seem to be manipulated and transformed in relation to their capacity to promote health, their market value, and their potential to construct new ethics of development. In this context, the translation of socially and culturally situated local knowledge about muthi into global pharmaceuticals creates new forms of agency as well as new power differentials between the different actors involved.

Turpentine is a fluid obtained by distillation of wood resins containing mixture of terpens. It can act as an irritant and sensitiser. Most common health problem among workers exposed to turpentine is contact dermatitis. Little is know about turpentine to cause type I hypersensitivity reaction. We present a case of a 27-year old art painter using turpentine as a thinner for oil-based paints. She developed asthmatic reactions after 5 years of working with turpentine. A number of clinical procedures were performed, including clinical examination, routine laboratory tests, total serum IgE, skin prick tests to common aeroallergens, metal salts, oil-based paints and balsamic turpentine, resting spirometry test, histamine challenge, and a single-blind, placebo-controlled specific inhalation challenge with balsamic turpentine. Clinical findings and laboratory test results were normal but a significant bronchial hyperreactivity was found. During the specific challenge, dyspnoea and decreased forced expiratory volume (FEV1) were observed in late phase of asthmatic reaction. An increased proportion of eosinophils in induced sputum could also be noted 24 h after the challenge. Positive clinical response to the specific challenge as well as the morphological changes found in induced sputum served as the basis for diagnosing occupational asthma. To our knowledge, this is the first well-documented case of turpentine-induced occupational asthma.

Gregório Lopes (c. 1490-1550) was one of the most prominent painters of the renaissance and Mannerism in Portugal. The painting "Mater Misericordiae" made for the Sesimbra Holy House of Mercy, circa 1535-1538, is one of the most significant works of the artist, and his only painting on this theme, being also one of the most significant Portuguese paintings of sixteenth century. The recent restoration provided the possibility to study materially the painting for the first time, with a multianalytical methodology incorporating portable energy-dispersive X-ray fluorescence spectroscopy, scanning electron microscopy-energy-dispersive spectroscopy, micro-X-ray diffraction, micro-Raman spectroscopy and high-performance liquid chromatography coupled to diode array and mass spectrometry detectors. The analytical study was complemented by infrared reflectography, allowing the study of the underdrawing technique and also by dendrochronology to confirm the date of the wooden panels (1535-1538). The results of this study were compared with previous ones on the painter's workshop, and significant differences and similitudes were found in the materials and techniques used.

Recent investigations of the astronomical work of the Byzantine Platonist George Gemistus Plethon provided the motivation, for Plethon's work encapsulated to many of the cross-currents flowing in astronomy in the early fifteenth century. At a time when the Byzantine world was in a state of collapse, and perhaps for that reason was more susceptible to foreign influence, Plethon drew not only on Ptolemy, but on the Greek Persian Syntaxis, and on al-Bāttani mediated through Hebrew. Both Plethon and his star pupil Cardinal Bessarion were great benefactors of scholarship, science, and philosophy in Renaissance Italy.

The Cucurbit Images (1515–1518) of the Villa Farnesina, Rome

JANICK, JULES; PARIS, HARRY S.

2006-01-01

• Background The gorgeous frescoes organized by the master Renaissance painter Raphael Sanzio (1483–1520) and illustrating the heavenly adventures of Cupid and Psyche were painted between 1515 and 1518 to decorate the Roman villa (now known as the Villa Farnesina) of the wealthy Sienese banker Agostino Chigi (1466–1520). Surrounding these paintings are festoons of fruits, vegetables and flowers painted by Giovanni Martini da Udine (1487–1564), which include over 170 species of plants. A deconstruction and collation of the cucurbit images in the festoons makes it possible to evaluate the genetic diversity of cucurbits in Renaissance Italy 500 years ago. • Findings The festoons contain six species of Old World cucurbits, Citrullus lanatus (watermelon), Cucumis melo (melon), Cucumis sativus (cucumber), Ecballium elaterium (squirting cucumber), Lagenaria siceraria (bottle gourd) and Momordica balsamina (balsam apple), and two or three species of New World cucurbits, Cucurbita maxima, C. pepo and, perhaps, C. moschata (pumpkin, squash, gourd). The images of C. maxima are the first illustrations of this species in Europe. PMID:16314340

The lead-poisoned genius: saturnism in famous artists across five centuries.

PubMed

Montes-Santiago, Julio

2013-01-01

Lead poisoning (saturnism) has been present throughout the history of mankind. In addition to possible ingestion from contaminated food, one of the most important ways in which poisoning caused morbid processes was by occupational exposure. This exposition was pandemic in the Roman Empire, and it has been claimed that it contributed to its fall, but it also caused numerous epidemics in Western countries until the nineteenth century. In the case of artists, and since the Renaissance period, this toxicity has been called painter's colic or painter's madness. The latter term is partly due to the mental disorders displayed by some of the great masters, including Michelangelo and Caravaggio, although it was long recognized that even house and industrial painters were prone to the disorder. This chapter examines the historical evidence of recognition of such toxicity and discusses the controversies raised by the possibility of professional lead poisoning in great artists. In addition to those mentioned above, many other artists across several centuries will be discussed, some being Rubens, Goya, Fortuny, Van Gogh, Renoir, Dufy, Klee, Frida Kahlo, and Portinari. This chapter also briefly mentions the possibility of lead poisoning in two famous composers: Beethoven and Handel. Whether suffering from lead poisoning or not, about which we cannot always be sure, we should still highlight and admire such geniuses fighting their disorders to bequeath us their immortals works. © 2013 Elsevier B.V.

Building an urban 'renaissance': fragmented services and the production of inequality in Greater Downtown Detroit.

PubMed

Doucet, Brian; Smit, Edske

2016-01-01

Downtown Detroit has been undergoing a renaissance in recent years which is in stark contrast to the economic and social situation in much of the rest of the city. This renaissance has been taking place despite the city's ability to provide good municipal services such as streetlights, security, public space and transport. This article focuses on how four areas which constitute part of Greater Downtown Detroit have relied on different combinations of actors to create and provide the services and amenities deemed necessary for capital investment and middle-class consumption. Each area has its own initiatives and actors who implement them, further fragmenting the city between its core and periphery. Renewed public spaces, private police forces and resident initiatives in middle-class neighborhoods have been created to serve specific needs of the small areas they serve. Rather than being unique, Detroit is an extreme example of fragmented and polarized urbanism which is part and parcel of contemporary cities. We argue that rather than passively reflecting existing socio-spatial divides, these private initiatives in Greater Downtown Detroit actively contribute to the production of sociospatial inequalities across the city.

The Oculist's Eye: Connections between Cataract Couching, Anatomy, and Visual Theory in the Renaissance.

PubMed

Baker, Tawrin

2017-01-01

We now know that cataract couching involves depressing an occluded crystalline lens to the bottom of the vitreous chamber, but from the time of Galen until the seventeenth-century cataracts were thought to be separate concretions arising between the crystalline lens and the pupil. From Antiquity through the Renaissance, the combination of visual theory in which the crystalline humor is the author of vision, and surgical experience—that couching cataracts restored some degree of sight—resulted in anatomists depicting a large space between the crystalline lens and the pupil. In the Renaissance, oculists—surgical specialists with little higher education or connections to learned surgery or medicine—overwhelmingly performed eye surgeries. This article examines how the experience and knowledge of oculists, of barber-surgeons, and of learned surgeons influenced one another on questions of anatomy, visual theory, and surgical experience. By analyzing the writings of the oculist George Bartisch (c. 1535–1607), the barber-surgeon Ambroise Paré (1510–1590), and the learned surgeon Hieronymus Fabricius ab Aquapendente (1533–1619), we see that the oculists’ understanding of the eye—an eye constructed out of the probing, tactile experience of eye surgery—slowly lost currency among the learned toward the beginning of the seventeenth century.

Books, printing and medicine in the Renaissance.

PubMed

Nutton, Vivian

2005-01-01

The history of the medical book in the Renaissance is only just beginning: there still are enormous gaps in our knowledge. Some general points may be emphasised: doctors, surgeons and apothecaries were often literate; the culture of the doctor was founded at least as much upon the book as upon practical experience. Much is known about the history of the printing press: but in focusing on expensive, luxury books such as Vesalius' Fabrica we often leave out average products such as the many other anatomy books printed in the 16th century. The most significant feature of printing is perhaps the increase of the amount and variety of what was available and accessible to readers. Looking specifically at one type of book, the plague treatise, the amalgamation of public and private allowed by the printing press becomes apparent. Knowledge was disseminated from universities to the general public: plague texts are scattered in many different private and public libraries, and any attempt at a general survey is bound to be provisional.

Subterranean Fire. Changing theories of the earth during the Renaissance.

PubMed

Vermij, R

1998-11-01

Aristotle described the earth as a cold and dry body and paid no attention to the phenomenon of terrestrial heat. Renaissance physicians, by contrast, when seeking to understand the origin of hot springs in the context of their balneological studies, came to defend a theory of subterranean fires. This tradition, which started in Italy, became widely known through the works of Georgius Agricola. But although it had implications for the explanation of further natural phenomena, it remained almost exclusively confined to medical circles. As far as physics as an academic discipline was concerned, the ideas concerning subterranean fire were hardly taken note of. Only with the collapse of Aristotelian philosophy in the seventeenth century could these by then "old innovations" obtain a wider significance.

The environmental education in the Italian Renaissance: the geoethical model of Machiavelli

NASA Astrophysics Data System (ADS)

Liserre, Battista; De Pascale, Francesco

2016-04-01

The importance of the environmental and geoethical education is also present in the thought of one of the greatest intellectuals of the Italian Renaissance: the philosopher Niccolò Machiavelli (1469-1527). In the "Discorsi" of Machiavelli, the natural character of the place where a city is built is a determining factor in the overall measure of the need on the character of the citizens; but the barren place, if can keep away the people from idleness, and thereby constitute an essential tool of virtuous civic life, prevents the development of the power which can be fostered only by the fertility of the site. It may give rise own laziness which hinders the development of virtue; and then, according to Machiavelli, laws must be to impose the need to produce good behavior through education. Already in the Renaissance, Machiavelli recognized the importance of establishing a harmonious relationship between man and environment and suggested that the institutions should give a virtuous model of environmental education. The physiognomy of the geographical and natural environment conditions in an essential way the exercise of civil life and the development of virtues. If the Rome's model imposes the primacy of fertile places, it happens, however, that, in his general conception of virtue and of historical dialectic, Machiavelli tended toward ultimately to increased functionality of the desolate places, which make difficult the life, and through the exercise of the need, make men more virtuous, keeping them away from the destructive threat of idleness. This aspect emerges from a different perspective, but convergent in "Asino" of Machiavelli (Chapter V). The link between the natural places and civic life that takes place isn't something absolutely default. Men's work, orders underpinning their collective life, laws that place the compulsion of necessity by the behavior of citizens, change the data of nature. Although the structure of a territory unequally, according to

Characterisation and reproduction of yellow pigments used in central Italy for decorating ceramics during Renaissance

2006-06-01

This study presents the characterisation of prototypical yellow pigments used during the Renaissance period in Italy and the successful reproduction of homologous materials in accordance with the ancient recipes. Moreover, a large number of yellow decorative layers of Sicilian ceramic artefacts dated back from 13th to the 19th century have been selected and the main chemical, structural and minero-petrografic features have been studied by X-ray diffraction, optical microscopy and scanning electron microscopy-energy dispersive spectrometry. These results have been compared with literature data of some yellow decorations of Renaissance ceramics made in central Italy. Comparison has also been made with homologous materials that have been successfully reproduced in accordance with ancient recipes described by Cipriano Piccolpasso in the textbook: “I Tre Libri dell’Arte del Vasaio” using the same ingredients proposed by this artist. Such yellow materials reproduce the typical yellow colorants used by craftsmen of relevant sites for ceramic fabrication in central Italy, namely Città di Castello, Urbino and Castel Durante, during the 16th century. Comparative arguments have shown some intriguing differences that are indicators of both technological transfer processes between central and southern Italy as well as of some local implementations likely due to specific raw materials locally available.

It consisted of a true medical bandage, covering a large syphilitic cutaneous ulcer, with a sulphur-embedded wad still in situ. The bandage has a very peculiar shape, rather different from the usual dressings described in the contemporary medical texts: a central rectangular pad, used as compressing appliance, is provided with a sort of pocket containing ivy leaves. The function of the dressing was not only to cover and protect the ulcer, but also to apply a plant drug. This is the first case of ancient medical bandage studied directly on a mummified body.

A 46-year-old man who had worked as a bumper spray painter in an automobile body shop for 15 years developed lung cancer. The patient was a nonsmoker with no family history of lung cancer. To determine whether the cancer was related to his work environment, we assessed the level of exposure to carcinogens during spray painting, sanding, and heat treatment. The results showed that spray painting with yellow paint increased the concentration of hexavalent chromium in the air to as much as 118.33 μg/m3. Analysis of the paint bulk materials showed that hexavalent chromium was mostly found in the form of lead chromate. Interestingly, strontium chromate was also detected, and the concentration of strontium chromate increased in line with the brightness of the yellow color. Some paints contained about 1% crystalline silica in the form of quartz. PMID:24422178

The Grand Ethiopian Renaissance Dam: Source of cooperation or contention?

2016-01-01

This paper discusses the challenges and benefits of the Grand Ethiopian Renaissance Dam (GERD), which is under construction and expected to be operational on the Blue Nile River in Ethiopia in a few years. Like many large-scale projects on transboundary rivers, the GERD has been criticized for potentially jeopardizing downstream water security and livelihoods through upstream unilateral decision making. In spite of the contentious nature of the project, the authors argue that this project can provide substantial benefits for regional development. The GERD, like any major river infrastructure project, will undeniably bring about social, environmental, and economic change, and in this unique case has, on balance, the potential to achieve success on all fronts. It must be stressed, however, that strong partnerships between riparian countries are essential. National success is contingent on regional cooperation.

On the Time of the Intellect: The Interpretation of De Anima 3.6 (43ob 7-20) in Renaissance and Early Modern Italian Philosophy.

PubMed

Dubouclez, Olivier

2015-01-01

This article argues that an original debate over the relationship between time and the intellect took place in Northern Italy in the second half of the sixteenth century, which was part of a broader reflection on the temporality of human mental acts. While human intellectual activity was said to be 'above time' during the Middle Ages, Renaissance scholars such as Marcantonio Genua (1491-1563), Giulio Castellani (1528-1586), Antonio Montecatini (1537-1599) and Francesco Piccolomini (1520-1604), greatly influenced by the Simplician and Alexandrist interpretations of Aristotle's works, proposed alterna- tive conceptions based on the interpretation of De anima 3.6 (430b 7-20) according to which intellectual acts happen in a both 'undivided' and 'divisible time'. In order to explain Aristotle's puzzling claim, they were led to conceive of intellectual activity as a process similar to sensation, corresponding to a certain lapse of time (Castellani), an instant (Montecatini), or a mix of instantaneousness and concrete duration (Piccolomini), depending on their theoretical options.

Drivers for the renaissance of coal

Steckel, Jan Christoph; Edenhofer, Ottmar; Jakob, Michael

2015-01-01

Coal was central to the industrial revolution, but in the 20th century it increasingly was superseded by oil and gas. However, in recent years coal again has become the predominant source of global carbon emissions. We show that this trend of rapidly increasing coal-based emissions is not restricted to a few individual countries such as China. Rather, we are witnessing a global renaissance of coal majorly driven by poor, fast-growing countries that increasingly rely on coal to satisfy their growing energy demand. The low price of coal relative to gas and oil has played an important role in accelerating coal consumption since the end of the 1990s. In this article, we show that in the increasingly integrated global coal market the availability of a domestic coal resource does not have a statistically significant impact on the use of coal and related emissions. These findings have important implications for climate change mitigation: If future economic growth of poor countries is fueled mainly by coal, ambitious mitigation targets very likely will become infeasible. Building new coal power plant capacities will lead to lock-in effects for the next few decades. If that lock-in is to be avoided, international climate policy must find ways to offer viable alternatives to coal for developing countries. PMID:26150491

A pair of little gilded shoes: commission, cost, and meaning in Renaissance footwear.

O'Malley, Michelle

2010-01-01

This article focuses on women's luxury footwear to examine issues of economic, material, and familial life in Renaissance Italy. It uses graphic work by Albrecht Dürer to explore footwear design, and draw from disparate sources to propose a new method for evaluating its cost. The article argues that sumptuous footwear was available for a range of prices that are not reflected in surviving payment records, and that it was largely less expensive than moralists and legislators implied. In conclusion, it employs Minerbetti documentation to consider the role particular shoes may have played in developing personal subjectivity.

Ethiopia's Grand Renaissance Dam: Implications for Downstream Riparian Countries

Ethiopia has begun seriously developing their significant hydropower potential by launching construction of the Grand Ethiopian Renaissance Dam (GERD) on the Blue Nile River to facilitate local and regional growth. Although this has required substantial planning on Ethiopia's part, no policy dictating the reservoir filling rate strategy has been publicly issued. This filling stage will have clear implications on downstream flows in Sudan and Egypt, complicated by evaporative losses, climate variability, and climate change. In this study, various filling policies and future climate states are simultaneously explored to infer potential streamflow reductions at Lake Nasser, providing regional decision-makers with a set of plausible, justifiable, and comparable outcomes. Schematic of the model framework Box plots of 2017-2032 percent change in annual average streamflow at Lake Nasser for each filling policy constructed from the 100 time-series and weighted precipitation changes. All values are relative to the no dam policy and no changes to future precipitation.

Music as therapy in early history.

PubMed

Thaut, Michael H

2015-01-01

The notion of music as therapy is based on ancient cross-cultural beliefs that music can have a "healing" effect on mind and body. Explanations for the therapeutic mechanisms in music have almost always included cultural and social science-based causalities about the uses and functions of music in society. However, it is also important to note that the view of music as "therapy" was also always strongly influenced by the view and understanding of the concepts and causes of disease. Magical/mystical concepts of illness and "rational" medicine probably lived side by side for thousands of years. Not until the late-nineteenth and early-twentieth centuries were the scientific foundations of medicine established, which allowed the foundations of music in therapy to progress from no science to soft science and most recently to actual brain science. Evidence for "early music therapy" will be discussed in four broad historical-cultural divisions: preliterate cultures; early civilizations in Mesopotamia, Egypt, Israel; Greek Antiquity; Middle Ages, Renaissance, and Baroque. In reviewing "early music therapy" practice, from mostly unknown periods of early history (using preliterate cultures as a window) to increasingly better documented times, including preserved notation samples of actual "healing" music, five theories and applications of early music therapy can be differentiated. © 2015 Elsevier B.V.

We present results on the formation of Population III (Pop III) stars at redshift 7.6 from the Renaissance Simulations, a suite of extremely high-resolution and physics-rich radiation transport hydrodynamics cosmological adaptive-mesh refinement simulations of high-redshift galaxy formation performed on the Blue Waters supercomputer. In a survey volume of about 220 comoving Mpc{sup 3}, we found 14 Pop III galaxies with recent star formation. The surprisingly late formation of Pop III stars is possible due to two factors: (i) the metal enrichment process is local and slow, leaving plenty of pristine gas to exist in the vast volume; and (ii) strongmore » Lyman–Werner radiation from vigorous metal-enriched star formation in early galaxies suppresses Pop III formation in (“not so”) small primordial halos with mass less than ∼3 × 10{sup 7} M {sub ⊙}. We quantify the properties of these Pop III galaxies and their Pop III star formation environments. We look for analogs to the recently discovered luminous Ly α emitter CR7, which has been interpreted as a Pop III star cluster within or near a metal-enriched star-forming galaxy. We find and discuss a system similar to this in some respects, however, the Pop III star cluster is far less massive and luminous than CR7 is inferred to be.« less

Solvent exposure and related work practices amongst apprentice spray painters in automotive body repair workshops.

Winder, C; Turner, P J

1992-08-01

As part of a multidisciplinary study into the health effects of solvents, workplace assessments and airborne solvent vapour monitoring was conducted in 46 spray painting workshops in the Sydney metropolitan area. Breathing-zone samples were taken from 50 apprentices and 14 experienced spray painters. An interview schedule was developed to obtain information about the use of acrylic or two-pack paint systems, the use of engineering controls, the use of personal protective equipment and the availability of material safety data sheets. Contaminants typical of the chemical products used in this industry were encountered (aromatic hydrocarbons, C5-C7 aliphatic hydrocarbons, ketones, esters). The results of airborne solvent monitoring indicate a total solvent exposure in the range 1-99% of a combined Worksafe Australia exposure standard, with a mean of 19%. Solvent exposure was highest when spraying acrylic paint in the open workshop and lowest when spraying two pack paint in a spray booth. Much the same personal protective equipment was available in all workshops, but wide variation in its use was observed. Material safety data sheets were not observed in any of the workshops.

Padeletti, G.; Fermo, P.; Gilardoni, S.; Galli, A.

In order to recover the ancient tradition concerning the materials used for the decoration, majolica shards produced during the Renaissance period in Casteldurante, a famous centre for ceramic production in Italy (Marche), have been examined. In the present study, pigments used for the decorations have been investigated by means of inductively coupled plasma optical emission spectrometry (ICP-OES), scanning electron microscopy/energy-dispersive X-ray spectroscopy (SEM-EDX) and diffuse-reflectance UV-Vis spectroscopy. Ochre, lead antimonate yellow, copper-based pigment and smalt have been used as colourants to obtain respectively yellow-orange, yellow, green and blue decorations in accordance with what is reported by the ancient recipes.

In search of Leonardo: computer-based facial image analysis of Renaissance artworks for identifying Leonardo as subject

2012-03-01

One of the enduring mysteries in the history of the Renaissance is the adult appearance of the archetypical "Renaissance Man," Leonardo da Vinci. His only acknowledged self-portrait is from an advanced age, and various candidate images of younger men are difficult to assess given the absence of documentary evidence. One clue about Leonardo's appearance comes from the remark of the contemporary historian, Vasari, that the sculpture of David by Leonardo's master, Andrea del Verrocchio, was based on the appearance of Leonardo when he was an apprentice. Taking a cue from this statement, we suggest that the more mature sculpture of St. Thomas, also by Verrocchio, might also have been a portrait of Leonardo. We tested the possibility Leonardo was the subject for Verrocchio's sculpture by a novel computational technique for the comparison of three-dimensional facial configurations. Based on quantitative measures of similarities, we also assess whether another pair of candidate two-dimensional images are plausibly attributable as being portraits of Leonardo as a young adult. Our results are consistent with the claim Leonardo is indeed the subject in these works, but we need comparisons with images in a larger corpora of candidate artworks before our results achieve statistical significance.

Pharmacy, Testing, and the Language of Truth in Renaissance Italy

summary This article examines the role of testing and innovation in sixteenthcentury Italian pharmacy. I argue that apothecaries were less concerned with testing drugs for efficacy or creating novel products than with reactivating an older Mediterranean pharmacological tradition and studying the materials on which it relied. Their practice was not driven by radical experimentation but by a "culture of tweaking"—of minute operational changes to existing recipes and accommodation of their textual variants—which was rooted in the guild economy fostering incremental over radical innovation and in a humanist reevaluation of past autorities. Workshop practice was also increasingly driven by a new ideal of staying true to nature fostered by the period's botanical renaissance. This led to an emphasis on ingredients over processes in the shop, and found clearest expression in the elaboration of a taxonomic "language of truth" that helped apothecaries discern between authentic and inauthentic materia medica and harness their sincerity in lieu of testing effectiveness.

A scholarly intermediary between the Ottoman Empire and Renaissance Europe.

Morrison, Robert

2014-03-01

This essay studies Moses Galeano, a Jewish scholar with ties to Crete and the Ottoman Sultan's court, who traveled to the Veneto around 1500. After describing Galeano's intellectual milieu, it focuses, first, on circumstantial evidence that he transmitted information central to the rise of Renaissance astronomy. Galeano knew of theories that strongly resemble portions of astronomy texts written by Giovanni Battista Amico and Girolamo Fracastoro at Padua a few decades later. He also knew about theories pioneered by the Damascene Ibn al-Shāţir (d. 1375) that strongly resemble portions of Copernicus's work. Next, the article turns to concrete evidence showing that Galeano was part of a network of Jewish scholars who did have contact with Christian scholars in Europe. The essay concludes that, while it is impossible to prove that Galeano had direct contact with Copernicus, he most likely had contact with some European astronomer(s) in the Veneto.

The political uses of astrology: predicting the illness and death of princes, kings and popes in the Italian Renaissance.

PubMed

Azzolini, Monica

2010-06-01

This paper examines the production and circulation of astrological prognostications regarding the illness and death of kings, princes, and popes in the Italian Renaissance (ca. 1470-1630). The distribution and consumption of this type of astrological information was often closely linked to the specific political situation in which they were produced. Depending on the astrological techniques used (prorogations, interrogations, or annual revolutions), and the media in which they appeared (private letters or printed prognostica) these prognostications fulfilled different functions in the information economy of Renaissance Italy. Some were used to legitimise the rule of a political leader, others to do just the opposite. Astrological prorogations and interrogations were often used to plan military and political strategies in case of the illness or death of a political leader, while astrological prognostications were generally written to promote certain political leaders while undermining others. While certainly often partisan to this game, astrologers, for their part, worked within a very well established tradition that gave authority to their forecasts. This paper argues that, as indicators of deeper political tensions otherwise not always explicitly manifest, these prognostications are privileged sources of information providing a better understanding of the political history of the period.

This article presents the biographies of the apothecaries who lived in the Rue Saint-Honoré in Paris in the 17th century. Two major facts emerge from this study. The first concerns the formation of a family network involving the apothecaries and the royal artists. The apothecaries Antoine and Jacques Grégoire became allied with Simon Vouet, the first painter of Louis XIII . Links were also made between Antoine Grégoire and Jacques Sarazin, the King’s sculptor, and then with Michel Corneille, painter to the King. The famous painting by Simon Vouet hanging in the assembly hall of the Faculty of Pharmacy in Paris is probably the fruit of his collaboration with Jacques Grégoire, his brother-in-law and an erudite botanist. The other notable fact concerns the relations between Anne de Furnes, widow of Antoine Brulon, the rich apothecary to the King Antoine Brulon, and Molière, both in Paris and in the village of Auteuil.

[Sabuco's suco nerveo and the origins of neurochemistry in the Spanish Renaissance].

PubMed

Martin Araguz, A; Bustamante Martinez, C; Fernandez Armayor, V

In the 16th century, at the height of the Spanish Renaissance, Bachiller Miguel Sabuco revolutionised medical theories about brain physiology with the publication of his work Nueva Filosof a in 1587. This work, which is mysteriously attributed to his daughter Luisa Oliva, presents a surprisingly gynocentric ideology for its time and has been reprinted on numerous occasions since its first edition saw the light. Sabuco s ideas have been plagiarised by such renowned authors as Descartes, Willis and Glisson. In stark contrast to the Arabized galenism based on the criterion of authority that predominated the medical practice of his time, Nueva Filosof a empirically promoted a modern approach to neurophysiology. This becomes even more worthy of merit if we bear in mind that Sabuco was not trained as a doctor but instead worked as an apothecary in Alcaraz (Albacete, Spain). The Bachiller granted the brain a commanding role over the organisation of the body for the first time in the history of medicine. He not only developed the surprising theory of succo nervoso (the nervous sap, or original neurotransmitting substance), but also an elegant digression on human nature that puts forward solid arguments about the dualist relation between mind and brain. He examined the association between emotional and physical health and explained how the emotions can impair health and lead to early death, which means he was also a pioneer in the development of psychosomatic medicine. Besides constituting the most illustrious forerunner of modern day neurochemistry, Sabuco s work also encourages doctors to treat their patients in an integral manner, with equal attention being given to the body, mind and soul. It comes as no surprise, then, that many aspects of his work can still be compared to modern medical and philosophical thought.

Malaria in the Renaissance: remedies from European herbals from the 16th and 17th century.

From antiquity up into the 20th century tertian and quartan malaria which are caused by the parasites Plasmodium vivax and Plasmodium malariae were widespread in Central Europe. Hundreds of different remedies against malaria can be found in herbals from the Renaissance. To document and discuss from a modern pharmacological viewpoint the old remedies described in eight 16th and 17th century herbals written in German. Eight of the most important herbals of the 16th and 17th century including Bock (1577), Fuchs (1543), Matthiolus (1590), Lonicerus (1560), Brunfels (1532), Zwinger (1696), and Tabernaemontanus (1591 and 1678) were searched for terms related to malaria, and documented plants and recipes described for its treatment. Additionally the overlapping of these remedies with those in De Materia Medica by the Greek physician Dioscorides was studied. Three hundred and fourteen taxa were identified in the herbals for this indication. Recent pharmacological data was found for just 5% of them. The influence of De Materia Medica was shown to be negligible with only 3.5% of the remedies in common. European Renaissance herbals may be a valuable source of information for the selection of plants for focussed antiplasmodial screening programmes, but have received only little scientific attention. Antimalarial remedies from these herbals must be viewed as independent sources of knowledge separate from Dioscorides' De Materia Medica. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

1994-01-01

Current conceptualizations of sexual identity in the West are not necessarily useful to an historian investigating "lesbianism" in the social history and visual representations of different periods. After an overview of Renaissance documents treating donna con donna relations which examines the potentially positive effects of condemnation and silence, the paper focuses on Diana, the goddess of chastity, who bathed with her nymphs as an exemplar of female bodies preserved for heterosexual, reproductive pleasures. Yet the self-sufficiency and bodily contact sometimes represented in images of this secluded all-female gathering might suggest "deviant" responses from their viewers.

Geodiversity and biodiversity interactions in the sand landscapes of the Netherlands on 19th and early 20th century landscape paintings

NASA Astrophysics Data System (ADS)

Jungerius, Pieter; van den Ancker, Hanneke

2014-05-01

Sand landscapes occupy about half of the territory of the Netherlands. Apart from an insignificant amount of Tertiary deposits, these sands are of Pleistocene and Holocene age. They include Saalian push moraines, Weichselian cover sands and Holocene drift sands. To these geological landscapes, cultural variants should be added such as the essen, i.e. a landscape with plaggen soils, and reclaimed lands (e.g. former moors). Not included are the coastal sands, which we dealt with in an earlier EGU contribution (van den Ancker & Jungerius 2012). Nature and man created a wide variety of sceneries that inspired painters in the 19th and early 20th century (Jungerius et al. 2012). Painter communities on the sandy soils flourished in Oosterbeek/Wolfheze, Laren/Blaricum, Nijkerk, Nunspeet/Elspeet, Hattem and Heeze. Many of the landscape paintings are found in the database of Simonis en Buunk that can be freely consulted on line (http//www.simonis&buunk.com). For this presentation we selected specimens that show geodiversity-biodiversity relationships, some of which have changed since. Painters of push moraines were attracted by the rolling terrain, the dry valleys and occasionally the colourful podzol soil profiles. Popular themes in the cover sands were the undulating relief and heathlands with herds of sheep, sandy footpaths and country roads with erosion phenomena. The dynamics of erosion captivated the painters of Holocene drift sand scenery, as did the bare fields of cultivated lands. Their paintings show the rural areas that since the beginning of the 20th century lost their traditional charm in large-scale re-allotment schemes and artificial nature-building project, that changed geodiversity-biodiversity relationships. Changes in the sandy terrains that can be inferred from the paintings are on a landscape scale, the scale of the landform and vegetation type, and are illustrated by changes in colour, pattern, structure and texture. Examples are: · active drift sands

Renaissance blue decorated pottery fragments from the archaeological site of Caltagirone (Sicily, Italy) were analysed by scanning electron microscopy - energy dispersive X-ray spectrometry (SEM/EDS). The samples were dated back to 16th century AD on the basis of archaeological observations. The micro-chemical analyses were performed on the ceramic body and the surface decorated layer of the samples. Particularly, the investigation was addressed the characterization of the coating blue decorations. The obtained results allowed us to clearly identify smalt as pigment. Also the presence of arsenic (As) was revealed and the Co/As ratio values were calculated and related to the different process used for the pigment preparation. Further spectroscopic analyses, performed through X-ray absorbance spectroscopy (XAS), carried out at the Co K-edge, confirmed the micro-analytical results and permitted us to identify the oxidation form and the local environment of cobalt atoms.

[Melancholia and reflection on the genius of Huarte de San Juan. Temperament and powers of the soul in Galenism of the Spanish Renaissance].

PubMed

Müller, Cristina

2002-01-01

Huarte de San Juan's Examen de ingenios (Examination of men's wits) of 1575 is one of the most significant Spanish contributions to Renaissance thought. The treatise reached an enormous popularity in Europe during the 16th and the 17th century as demonstrated by numerous translations in Italian, French, Portuguese, English, German or Dutch. However, it is barely known in modern times. Huart's doctrine illustrates the Renaissance attempt to restore the purity of ancient medicine, while proposing a "scientific" basis for the project of a systematic professional orientation. By means of the ancient theory of humours and that of the philosophical reflection on the genius, Huarte articulates a new pattern for the intellectual ability, seen as highly individual, but also deeply rooted in the biological nature of the human being The intellectual fecundity is explained by recourse to humoural physiology with a special focus on the traditional image of the melancholic temperament, redefined in the spirit of the pre-modern anthropology of the variety.

Western biomedical theory supported the idea of human female inferiority. The Aristotelian formulation was: Nature intends to produce the perfect male form with external genitalia; the female with internal genitalia is less than perfect and thus a defect of nature. In the Renaissance, peripubertal virilization in females was interpreted as further evidence that females were "defective" males capable of developing into the more perfect male form.

During the 1950s the efforts of an unlikely group composed of two colorful businessmen, a handful of physicists, and Air Force representatives helped to create a renaissance in general relativity research. Industrialist Agnew Bahson was an air conditioning magnate with connections to leading scientists, and the Air Force. In addition to his contribution to ``respectable'' physics, his life and death are shrouded in a cloak of UFO and anti-gravity conspiracy theories. Business theorist Roger Babson was driven to search for a solution to anti-gravity after first his sister and later his grandson drowned tragically as children. This presentation tells of the globe spanning, harrowing adventure of mountainside crashes, an international love affair, physicists masquerading as secretaries, the founding of Les Houches, the development of the first radar defense system and how Bahnson and Babson became benefactors of mainstream physics, leading to the creation of the Institute of Field Physics at the University of North Carolina Chapel Hill led by Cecile and Bryce DeWitt and ultimately to the groundbreaking research that predicted the Higgs boson.

Science, alchemy and light: paintings by Joseph Wright of Derby.

This article considers two paintings by the English painter, Joseph Wright of Derby (1734-97), 'An Experiment on a Bird in the Air Pump' and 'The Alchemist in Search of the Philosopher's Stone' as painterly reflections on the early industrial culture. Particularly interesting in the "Experiment on a Bird" is the broad spectrum of spectator's reactions to the experiment; this can be related to the contemporary debate on the contextualization of science.

Neuroaesthetic is a scientific discipline founded more than a decade ago and it refers to the study of the neural bases of beauty perception in art. The aim of this paper is to investigate the neuroelectrical correlates of brain activity of the observation of real paintings showed in a national fine arts gallery (Scuderie del Quirinale) in Rome, Italy. In fact, the present study was designed to examine how motivational factors as indexed by EEG asymmetry over the prefrontal cortex (relative activity of the left and right hemispheres) could be related to the experience of viewing a series of figurative paintings. The fine arts gallery was visited by a group of 25 subjects during an exhibition of the XVII century Dutch painters. Results suggested a strict correlation of the estimated EEG asymmetry with the verbal pleasantness scores reported by the subjects (p<0,05) and an inverse correlation of the perceived pleasantness with the observed painting's surface dimensions (p<0,002).

Pigment identification on ``Pietà'' of Barletta, example of Renaissance Apulian sculpture: A Raman microscopy study

A study of the original painting layer of the "Pietà" of Barletta, a polychrome statue, important example of Renaissance Apulian sculpture, was performed by μ-Raman spectroscopy. Vermilion was identified in the original layer of the blood drops on Jesus knee. Lazurite was identified as the original blue pigment on Our Lady's veil and lace, currently a yellow ochre-like color. The use of lazurite demonstrates the historical-artistic importance of this polychrome statue, and supports the hypothesis that this artwork was probably commissioned by Our Lady's devotees to itinerant artists inspired by the more precious Vesperbilder model.

The lives of Mary Foote: painter and Jungian.

Trousdell, Richard

2016-11-01

Mary Foote (1872-1968) was a successful early twentieth century American artist who suddenly closed her New York studio in 1926 to go to Zurich to study with Jung. There she joined his 'Interpretation of Visions' seminars (1930-1934), which she recorded and edited. This work won Jung's praise and his friendship, but all too often Foote was seen merely as a secretary or background figure. Deirdre Bair's biography of Jung suggested that Foote's life and work deserved fuller study, if only to rebalance our view of Jung's early women followers. This paper takes up that work to ask how Foote's early life and career led to her important work in preserving and describing Jung's earliest attempts to apply his theories to clinical practice. © 2016, The Society of Analytical Psychology.

The potentials of the Terahertz Time-Domain Imaging (THz-TDI) technique for a non-invasive inspection of panel paintings have been considered in detail. The THz-TD data acquired on a replica of a panel painting made in imitation of Italian Renaissance panel paintings were processed in order to provide insights as to the limits and potentials of the technique in detecting different kinds of underdrawings and paint layers. Constituent layers, construction techniques, and anomalies were identified and localized by interpreting the extracted THz dielectric stratigraphy.

The ``Nuclear Renaissance'' and the Spread of Nuclear Weapons

Lyman, Edwin S.

2007-05-01

As interest grows around the world in nuclear power as an energy source that could help control greenhouse gas emissions, some have proclaimed the arrival of a ``nuclear renaissance.'' But can the increased risks of more nuclear power be managed? The political crisis surrounding Iran's pursuit of uranium enrichment has exposed weaknesses in the nuclear nonproliferation regime. Also, al Qaeda's declared interest in weapons of mass destruction raises the concern that terrorists could acquire nuclear weapons by stealing materials from poorly secured facilities. Growth of nuclear energy would require the construction of many additional uranium enrichment plants. And the generation of more spent nuclear fuel without a credible waste disposal strategy would increase political support for reprocessing, which separates large quantities of weapon-usable plutonium from spent fuel. There is little evidence that the various institutional arrangements and technical schemes proposed to mitigate the security risks of a major nuclear expansion would be effective. This talk will focus on the measures necessary to allow large-scale global growth of nuclear power without resulting in an unacceptably high risk of nuclear proliferation and nuclear terrorism, and will discuss the feasibility of such measures.

SPATTER! SPATTER! SPATTER! Workers' health and the spray machine debate.

PubMed

Frounfelker, Rochelle L

2006-02-01

A conflict between industrialization and worker health developed in the painting industry during the early 1900s with the introduction of the spray machine. This technological innovation allowed the application of paint at greater speed and lower cost than hand painting and increased the rate at which painters were exposed to lead and other toxins contained in paint. From roughly 1919 to 1931, the painters' trade union clashed with employers, paint manufacturers, and legislatures over the impact of the spray machine on the health of workers and the need to enact legislation to regulate its use. While painters made gains on local, state, and national levels during the 1920s to prevent the use of the spray machine, their efforts ultimately failed.

Did Jan van Eyck build the first photocopier in 1432?

NASA Astrophysics Data System (ADS)

Stork, David G.

2003-12-01

Recently it has been claimed that some early Renaissance painters used concave mirrors to project real inverted images onto their supports (paper, canvas, oak panel, ...) which they then traced or painted over, and that this was an important source of the increase in realism in European painting around 1420. Key exhibits adduced as evidence in support of this bold theory are a pair of portraits by Jan van Eyck of Cardinal Niccolo Albergati(&?) - a silverpoint study of 1431 and a larger oil of 1432. The contours in these two works bear striking resemblance in form (after being appropriately scaled) and at least one distinctive "relative shift" - evidence that has led proponents of the projection theory to claim that the oil was copied by means of an epidiascope or primitive opaque projector, the shift due to an accidental "bump" during the copying process. We find several difficulties with this optical explanation: there are at least two relative shifts (one horizontal and one vertical), the latter being somewhat unlikely given the putative projection equipment and setup; these shifts are in the ratio of distances of nearly 1:2, a ratio that has no natural role in the projection explanation; any accidental "bump" would surely have been noticed by van Eyck, and if so desired, corrected by him; recent analysis shows physical evidence (tiny pinpricks presumably from mechanical compass) consistent with mechanical transfer that has no role in the optical explanation; and several other points. The fidelity of the copy as well as the direction and relative magnitudes of these shifts are, however, consistent with the use of a familiar grid construction and with mechanical transfer using drawing compass and ruler or Reductionszirkel. Further, there are prominent vertical Bruchkanten (fold or fraction) lines on the grounded paper in the silverpoint study whose orientation and separation have no natural role in an optical theory, but have a plausible role in other explanations

Pseudobulbar paralysis in the Renaissance: Cosimo I de' Medici case.

PubMed

Arba, F; Inzitari, D; Lippi, D

2014-07-01

Cosimo I de' Medici (1519-1574) was the first Grand Duke of Tuscany. He was one of the most important members of the Medici family. He was an excellent conqueror and a good politician. Moreover, he was able to attract and encourage artists, scientists and architects to promote Florence as the cultural capital of the Italian Renaissance. Historical chronicles report that he suffered from a stroke when he was 49 years old. Together with the acute manifestation of stroke, he displayed peculiar symptoms. He had gait disturbances and sphincter dysfunctions. His language became poor and hard to understand. His mood was very fluctuating and in the last years of his life he was a short-tempered man. In addition, he had a characteristic symptom, so-called pathological laughing and crying. The course of his disease was slow and stuttering. Taken together, these data seem to be one of the first reports of pseudobulbar paralysis. The disease of Cosimo I was probably due to a chronic cerebral vasculopathy, known as small vessels disease. We discuss this hypothesis regarding an ancient clinical case, with the support of current studies.

[The brothers of Jumiege--the peripheral nervous system in early French mythology].

PubMed

Brean, Are

2002-03-20

This article reviews the process of discovery of the nervous system from Pythagoras (570-500 BC) to Galen (130-201 AD). After Galen, no anatomical studies were performed before the renaissance. According to a legend, probably produced for political reasons, two brothers, sons of the French king Clovis II, revolted against their father and were sentenced to loose their physical powers by having the nerves of their arms and legs cut. They were then set adrift on the river Seine, stranding at the Jumiège monastery. The earliest written version of this legend stems from the fourteenth century; it was probably a part of the local French mythology. This indicates that the existence of the peripheral nervous system, and therefore also in part the knowledge contained in the early anatomical works, quite early may have been more or less known outside academic circles.

Patient-Reported Safety Information: A Renaissance of Pharmacovigilance?

2016-10-01

The role of patients as key contributors in pharmacovigilance was acknowledged in the new EU pharmacovigilance legislation. This contains several efforts to increase the involvement of the general public, including making patient adverse drug reaction (ADR) reporting systems mandatory. Three years have passed since the legislation was introduced and the key question is: does pharmacovigilance yet make optimal use of patient-reported safety information? Independent research has shown beyond doubt that patients make an important contribution to pharmacovigilance signal detection. Patient reports provide first-hand information about the suspected ADR and the circumstances under which it occurred, including medication errors, quality failures, and 'near misses'. Patient-reported safety information leads to a better understanding of the patient's experiences of the ADR. Patients are better at explaining the nature, personal significance and consequences of ADRs than healthcare professionals' reports on similar associations and they give more detailed information regarding quality of life including psychological effects and effects on everyday tasks. Current methods used in pharmacovigilance need to optimise use of the information reported from patients. To make the most of information from patients, the systems we use for collecting, coding and recording patient-reported information and the methodologies applied for signal detection and assessment need to be further developed, such as a patient-specific form, development of a severity grading and evolution of the database structure and the signal detection methods applied. It is time for a renaissance of pharmacovigilance.

A Nuclear Renaissance: The Role of Nuclear Power in Mitigating Climate Change

NASA Astrophysics Data System (ADS)

Winslow, Anne

2011-06-01

The U. N. Framework Convention on Climate Change calls for the stabilization of greenhouse gas (GHG) emissions at double the preindustrial atmospheric carbon dioxide concentration to avoid dangerous anthropogenic interference with the climate system. To achieve this goal, carbon emissions in 2050 must not exceed their current level, despite predictions of a dramatic increase in global electricity demand. The need to reduce GHG emissions and simultaneously provide for additional electricity demand has led to a renewed interest in the expansion of alternatives to fossil fuels—particularly renewable energy and nuclear power. As renewable energy sources are often constrained by the intermittency of natural energy forms, scale-ability concerns, cost and environmental barriers, many governments and even prominent environmentalist turn to nuclear energy as a source of clean, reliable base-load electricity. Described by some as a "nuclear renaissance", this trend of embracing nuclear power as a tool to mitigate climate change will dramatically influence the feasibility of emerging nuclear programs around the world.

The Tragedy of the Unexamined Cat: Why K-12 and University Education Are Still in the Dark Ages and How Citizen Science Allows for a Renaissance.

At the end of the dark ages, anatomy was taught as though everything that could be known was known. Scholars learned about what had been discovered rather than how to make discoveries. This was true even though the body (and the rest of biology) was very poorly understood. The renaissance eventually brought a revolution in how scholars (and graduate students) were trained and worked. This revolution never occurred in K-12 or university education such that we now teach young students in much the way that scholars were taught in the dark ages, we teach them what is already known rather than the process of knowing. Citizen science offers a way to change K-12 and university education and, in doing so, complete the renaissance. Here we offer an example of such an approach and call for change in the way students are taught science, change that is more possible than it has ever been and is, nonetheless, five hundred years delayed.

Identification of proteins in renaissance paintings by proteomics.

Tokarski, Caroline; Martin, Elisabeth; Rolando, Christian; Cren-Olivé, Cécile

2006-03-01

The presented work proposes a new methodology based on proteomics techniques to identify proteins in old art paintings. The main challenging tasks of this work were (i) to find appropriate conditions for extracting proteins from the binding media without protein hydrolysis in amino acids and (ii) to develop analytical methods adapted to the small sample quantity available. Starting from microsamples of painting models (ovalbumin-based, which is the major egg white protein, and egg-based paintings), multiple extraction solutions (HCl, HCOOH, NH3, NaOH) and conditions (ultrasonic bath, mortar and pestle, grinding resin) were evaluated. The best results were obtained using a commercial kit including a synthetic resin, mortar and pestle to grind the sample in an aqueous solution acidified with trifluoroacetic acid at 1% with additional multiple steps of ultrasonic baths. The resulting supernatant was analyzed by MALDI-TOF in linear mode to verify the efficiency of the extraction solution. An enzymatic hydrolysis step was also performed for protein identification; the peptide mixture was analyzed by nanoLC/nanoESI/Q-q-TOF MS/MS with an adapted chromatographic run for the low sample quantity. Finally, the developed methodology was successfully applied to Renaissance art painting microsamples of approximately 10 microg from Benedetto Bonfigli's triptych, The Virgin and Child, St. John the Baptist, St. Sebastian (XVth century), and Niccolo di Pietro Gerini's painting, The Virgin and Child (XIVth century), identifying, for the first time and without ambiguity, the presence of whole egg proteins (egg yolk and egg white) in a painting binder.

The Renaissance Kidney-Nephrology in and about the Sixteenth Century.

The endeavor to understand the workings of the human body is as old as civilization; but it is in the intellectual movement of the Renaissance that its actual scientific study began in earnest and has not ceased growing since then. It was in the 16th century that the study of organs was launched and with it that of the kidney, which was then conceived as an accessory organ to clear the excess water ingested with food. The study of the structural basis of kidney function was launched by Bartolomeo Eustachio (1514-1574); the elements of its physiology and pathology were promulgated by Jean Fernel (1497-1558), and that of the chemical study of urine and of the principal cause of kidney disease then, calculi, instigated by Joan Baptista Van Helmont (1577-1644). The methodological approaches of these and their contemporary investigators, which were crystallized and formulated by Francis Bacon (1561-1626), opened the gates of the Scientific Revolution that followed in the 17th century, beginning with that of describing the circulation in 1628 by William Harvey (1564-1657) that would finally free the kidney from the shackles imposed on it as a mere accessory organ to the liver in Galen's physiology. © 2012 Wiley Periodicals, Inc.

Pandolfo III Malatesta (1370-1427) was a leading figure of the Italian Renaissance. He was a valiant soldier and horseman with a very active life style. Historical sources report that he died of a fever in 1427. The tomb, containing his mummified body, has recently been discovered in Fano (Marche, Central Italy). After careful X-ray and videographic examination, autopsy was performed to diagnose possible pathologies. Samples of different tissues were collected and rehydrated by Sandison's method and submitted to routine histology processes. Sections of treated tissue were fixed on clean slides, stained with hematoxylin-eosin or Gardner's Trichromic and observed at light microscope. RESULTS AND CONCLUSIONS The autopsy showed good preservation of the skeletal muscles, cartilage, internal and external organs included prostate gland and penis. Macroscopic examination revealed stag-horn calculi (calcium urate) of the left kidney and a severe enlargement of the prostate, with calcifications detectable by X-ray and a large nodule protruding in the lumen of an ectatic urethra. Histology shows fibrous bands of connective and muscular tissue surrounding some circular and oblong lacunae, with no preservation of epithelial structures. The macroscopic and histological picture, showing clear prostatic nodular hyperplasia, makes this the first case described in paleopathology. Copyright 2000 Wiley-Liss, Inc.

A renaissance in marine pharmacology: from preclinical curiosity to clinical reality.

Marine pharmacology, the pharmacology of marine natural products, has been for some time more associated with marine natural products chemistry rather than mainstay pharmacology. However, in recent years a renaissance has occurred in this area of research, and has seen the US Food & Drug Administration (FDA) approval in 2004 of Prialt (ziconotide, omega-conotoxin MVIIA) the synthetic equivalent of a conopeptide found in marine snails, used for the management of severe chronic pain. Furthermore Yondelis) (trabectedin, ET-743) an antitumor agent scovered in a marine colonial tunicate, and now produced synthetically, receiving Orphan Drug designation from the European Commission (EC) and FDA for soft tissue sarcomas and ovarian cancer and its registration in 2007 in the EU for the treatment of soft tissue sarcoma. The approval/marketing of so few marine natural products has come after many years of research primarily by the academic community and the sporadic involvement of major pharmaceutical companies. This commentary, through the opinions provided by several leaders in the marine natural products field, will examine the potential reasons and perceptions from both the academic and pharmaceutical communities regarding the development of marine natural products as viable therapeutic entities.

Shakespeare and other English Renaissance authors as characterized by Information Theory complexity quantifiers

2009-03-01

We introduce novel Information Theory quantifiers in a computational linguistic study that involves a large corpus of English Renaissance literature. The 185 texts studied (136 plays and 49 poems in total), with first editions that range from 1580 to 1640, form a representative set of its period. Our data set includes 30 texts unquestionably attributed to Shakespeare; in addition we also included A Lover’s Complaint, a poem which generally appears in Shakespeare collected editions but whose authorship is currently in dispute. Our statistical complexity quantifiers combine the power of Jensen-Shannon’s divergence with the entropy variations as computed from a probability distribution function of the observed word use frequencies. Our results show, among other things, that for a given entropy poems display higher complexity than plays, that Shakespeare’s work falls into two distinct clusters in entropy, and that his work is remarkable for its homogeneity and for its closeness to overall means.

Evidence, logic, the rule and the exception in Renaissance law and medicine.

PubMed

Maclean, I

2000-01-01

This article sets out to investigate aspects of the uptake of Renaissance law and medicine from some of the logical and natural-philosophical components of the university arts course. Medicine is shown to have a much laxer operative logic than law, reflecting its commitment to the theory of idiosyncrasy as opposed to the demands made upon the law by the need for a uniform application of justice. Symptomatic of the different uptake are the contrasting meanings of "regulariter" and "generaliter" in the two disciplines. Whereas the law treats the rule as inviolable and the exception as only valid if made explicit in due legal form, medicine is able to conceive of a nature as a field of knowledge broader than that encompassed by its rules of art. Both law and medicine approach evidence in ways which reflect their attempts to keep apart the process of information-gathering from that of interpretation; this is exemplified by the legal computation of competing testimony on the one hand and by the various medical modes of sign interpretation on the other.

Heavenly Networks. Celestial Maps and Globes in Circulation between Artisans, Mathematicians, and Noblemen in Renaissance Europe.

PubMed

Gessner, Samuel

2015-01-01

The aim of this paper is to examine the iconography on a set of star charts by Albrecht Dürer (1515), and celestial globes by Caspar Vopel (1536) and Christoph Schissler (1575). The iconography on these instruments is conditioned by strong traditions which include not only the imagery on globes and planispheres (star charts), but also ancient literature about the constellations. Where this iconography departs from those traditions, the change had to do with humanism in the sixteenth century. This "humanistic" dimension is interwoven with other concerns that involve both "social" and "technical" motivations. The interplay of these three dimensions illustrates how the iconography on celestial charts and globes expresses some features of the shared knowledge and shared culture between artisans, mathematicians, and nobles in Renaissance Europe.

Darkness and depth in early Renaissance painting

NASA Astrophysics Data System (ADS)

Tyler, Christopher

2010-02-01

Contrast has always been appreciated as a significant factor in image quality, but it is less widely recognized that it is a key factor in the representation of depth, solidity and three-dimensionality in images in general, and in paintings in particular. This aspect of contrast was a key factor in the introduction of oil paint as a painting medium at the beginning of the fifteenth century, as a practical means of contrast enhancement. However, recent conservatorship efforts have established that the first oil paintings were not, as commonly supposed, by van Eyck in Flanders in the 1430s, but by Masolino da Panicale in Italy in the 1420s. These developments led to the use of chiaroscuro technique in various forms, all of which are techniques for enhanced shadowing.

Art, class and gender in Joseon dynasty Korea: representations of lower-class women by the scholar-painter Yun Duseo.

Chung, Saehyang P

2011-01-01

This paper examines several pioneering genre paintings by the important scholar painter Yun Duseo (1668-1715), with its focus on their artistic sources which have not yet been explored so far. Painted on ramie, 'Women Picking Potherbs' is one of the most intriguing examples among Yun Duseo's oeuvre, which encompasses a broad variety of themes, including genre imagery, landscapes, portraits, dragons, and horses. Even among Yun Duseo's genre paintings, 'Women Picking Potherbs' is extraordinary, as recent scholarship regards it as the earliest independent representation of lower-class women in the history of Korean art. In particular, Yun Duseo painted two women who were working ourdoors to gather spring potherbs. In a conservative Confucian society, it was extraordinary women who were working outdoors. Hence, Yun Duseo occupies a highly important place in Korean painting. Furthermore, even though Yun Duseo came from the upper-class, he often painted images of lower class people working. It is possible that Yun Duseo was familiar with the book titled "Tian gong kai wu" (Exploitation of the Works of Nature) which was published in the 17th century. By identifying the probable body of his artistic sources in the book known as "Tian gong kai wu," it will be possible to assess the innovations and limitations found in 'Women Picking Potherbs'.

"Treatises on Earthquakes" in late Renaissance (16th-17th cent), at the roots of historical seismology

NASA Astrophysics Data System (ADS)

Albini, P.

2009-04-01

It was soon after the damaging November 1570 earthquake at Ferrara, Northern Italy, that the academic Stefano Breventano from Pavia, a small town in Northern Italy as well, started to compose his "Treatise on the earthquake". Completed by September 1576, this 250-page manuscript was to remain unpublished for centuries. The critical edition recently appeared (Albini, 2007) was a due tribute to the remarkable amount of information put together by Breventano, an otherwise "obscure" literate who, before getting involved with earthquakes, had published a history of the antiquities and remarkable events at his hometown Pavia (1570). Indeed, he was not the first Renaissance author to pursue the goal of checking into the historical sources of the previous centuries in search of earthquakes and other natural phenomena. What is outstanding in his "Treatise" is that he suceeded in retrieving information on more than two hundred earthquakes, along two thousand years, between 504 B.C. and 1575 A.D., covering the whole Euro-Mediterranean region, and the West Indies in early 16th century. Breventano's essay is here presented, together with a comparison between his style and amount of information with those included in the work by the contemporary British author Stephen Batman, "The Doome warning all men to the Judgement" (1581). A later treatise is presented also, the work by Marcello Bonito (1690) "Terra Tremante [Trembling Earth]", which could easily be defined as a worldwide list of earthquakes. In structure and content, Bonito's work goes along the same lines of Breventano, and could be considered a precursor of today descriptive catalogues, because of his outstandingly modern approach that paved the way to modern historical seismology.

Juan Valverde de Amusco (c. 1525-c. 1564) is considered to have been the most important Spanish anatomist of the XVI century. A follower of Vesalius, he increased and divulged knowledge of anatomy during the Renaissance and his book The history of the composition of the human body was printed in Rome in 1556. The objective of this paper is to study the neuroanatomy in this book and present unpublished biographical data and describe the main contributions of this Castilian doctor to the neurosciences, in the context of Spanish medicine during the Renaissance period. He was born in the town of Hamusco (today Amusco) in the province of Palencia, which belonged to the Crown of Castile. Juan Valverde emigrated to Italy to improve his scientific knowledge. He carried out anatomical studies using the then revolutionary method of direct observation, as opposed to the Galenic criteria of authority inherited from the Medieval period. He trained in Padua under Realdo Colombo and lived in Rome where he practiced medicine until his death, becoming deservedly famous. He did not return to Spain since in the Spanish universities of the time there was a mentality which was reactionary to modern anatomy. His works, published in Italy but in the Spanish language, give an idea of the power of the Crown of Castile in the Europe of that period. The book is profusely illustrated with the first illustrations ever published in the history of printing, drawn by Nicolas Beatrizet. The book was sold widely and was translated and reedited on many occasions, until well into the XVIII century. For the first time Valverde made precise references to the minor circulation. He was the first anatomist to describe the muscles for movement of the eye correctly and the intracranial course of the carotid arteries. In his work he made the first drawing of the stapes, described by the Valencian Luis Collado. Vesalius and Valverde contributed decisively to the beginnings of modern neuroanatomy. Thanks to

Water splitting is the essential chemical reaction to enable the storage of intermittent energies such as solar and wind in the form of hydrogen fuel. The oxygen evolution reaction (OER) is often considered as the bottleneck in water splitting. Though metal oxides had been reported as OER electrocatalysts more than half a century ago, the recent interest in renewable energy storage has spurred a renaissance of the studies of transition metal oxides as Earth-abundant and nonprecious OER catalysts. This Perspective presents major progress in several key areas of the field such as theoretical understanding, activity trend, in situ and operando characterization, active site determination, and novel materials. A personal overview of the past achievements and future challenges is also provided.

What the discerning gaze of the art historian has deduced from comparisons in style namely, that the unsigned Baptism of Christ (dated 1567) comes from the hand of the master Cretan painter, El Greco is now investigated by the dispassionate eye of technology. The examination by means of analytical methods of diagnosis aimed at making an in-depth investigation into the hitherto unknown personal traits of the artist’s painting technique. By observing the cross-sections under the optical microscope and analyzing the materials through the application of μRaman and μFTIR spectroscopies and of high performance liquid chromatography (HPCL/DAD), it was possible to reveal the “fingerprints” of the artist’s brushwork. In his masterfully executed Baptism, El Greco has succeeded through his perspicacity and ingenuity, to combine traditional techniques of Byzantine icon-painting with the innovative practices of Venetian Renaissance art. The artist’s palette contains mineral, earth and natural organic pigments, as well as some synthetic ones of glass or resin base: lapis lazuli, indigo, lead-tin yellow, orpiment, yellow ochre, cochineal lake, copper resinate, burnt umber, lead white and carbon black. Furthermore, he introduces a layer of white imprimatura containing varied combinations of powdered glass and lead white. The detection of substantial similarities between the glass varieties used in the Baptism and those found in works by Venetian painters contemporary with El Greco (such as Tintoretto) further attests ascription of the Baptism to the period of the artist’s brief sojourn in Venice.

Selected decorated Renaissance ceramic fragments, found during the excavation of a Sicilian archaeological site (Caltagirone, Sicily, South Italy), have been studied by combining scanning electron microscopy (SEM), energy-dispersive X-ray spectrometry (EDS), and X-ray absorbance spectroscopy (XAS). The study was aimed at providing microchemical and microstructural characterization of the colored glazed coatings in order to elucidate the nature of the pigments in the decorative layers, and in the glaze itself. From the obtained results, the general perspective has been the identification of information to be used for a reliable recognition of the production techniques. In particular, XAS measurements, performed using synchrotron radiation (SR) as the source at the Cu K-edge, in the case of green decorations, provided structural information of the oxidation states and the local chemical environment of copper (neighboring atoms and bond distances).

Giovanni Pico della Mirandola and Angelo Poliziano were two of the most important humanists of the Italian Renaissance. They died suddenly in 1494 and their deaths have been for centuries a subject of debate. The exhumation of their remains offered the opportunity to study the cause of their death through a multidisciplinary research project. Anthropological analyses, together with documentary evidences, radiocarbon dating and ancient DNA analysis supported the identification of the remains attributed to Pico. Macroscopic examination did not reveal paleopathological lesions or signs related to syphilis. Heavy metals analysis, carried out on bones and mummified tissues, showed that in Pico's remains there were potentially lethal levels of arsenic, supporting the philosopher's poisoning theory reported by documentary sources. The arsenic concentrations obtained from analysis of Poliziano's remains, are probably more related to an As chronic exposure or diagenetic processes rather than poisoning.

Bismuth knowledge during the Renaissance strengthened by its use in Italian lustres production

NASA Astrophysics Data System (ADS)

Padeletti, G.; Fermo, P.

The knowledge of bismuth during the XV and XVI centuries represents an open question since, according to some authors, this element was confused with lead, tin and silver. On the contrary, G. Agricola (1494-1555), the pioneer of mineralogical science in Europe, in his two works (De Natura Fossilium, Lib X, 1546 and Bermannus Sive De Re Metallica Dialogus, 1528) asserts that bismuth was considered as an element distinct from the other metals at that time. This question gave rise to some interest, and von Lippmann in 1930 wrote a treatise dealing with the history of bismuth between 1400 and 1800. In this work we present the results obtained on Italian and Hispano-Moresque shards studied by means of X-ray diffraction, atomic absorption spectrometry with electrothermal atomisation, inductively coupled plasma optical emission spectrometry and scanning electron microscopy. It seems that our work could provide a new and important contribution to this debate, because we found bismuth in lustre composition of Renaissance shards produced in central Italy. Furthermore, we found that it could also be considered as a discriminating element between Italian and Hispano-Moresque productions, useful to assess their origin.

Microchemical investigation on Renaissance coins minted at Gubbio (Central Italy)

NASA Astrophysics Data System (ADS)

Ingo, G. M.; de Caro, T.; Padeletti, G.; Chiozzini, G.

The bulk and surface chemical composition of Renaissance coins minted at Gubbio (Central Italy) from 1508 to 1516 and from 1521 to 1538 by Francesco Maria della Rovere is investigated by means of the combined use of different analytical techniques such as scanning electron microscopy (SEM), energy dispersive spectrometry (EDS), and optical microscopy (OM). The aim of the work is to determine the bulk chemical composition of these commonly used coins at Gubbio, to ascertain their surface nature and if they were coated by a thin film of silver or other white metals similar to silver. The results indicate that the coins were produced by coating a copper core with a thin film of silver and antimony, and also with lead whose thickness is of a few microns which is now scarcely present because the original silvered surface was almost entirely removed by degradation phenomena. Furthermore, the SEM+EDS results show that the surface content of silver and antimony cannot be attributed to long-term selective corrosion phenomena leaving the coin slightly silver or antimony enriched. Therefore, the presence of silver or apparently silver-like metals i.e. antimony and lead, could be considered as a deliberate surface finishing of the coins obtained via inverse segregation or intentional selective corrosion based on pickling solutions or a combination of them. From a historical point of view the presence of a Ag or Sb film on the surface of the coins discloses the occurrence of a period of economic difficulties.

The use of truffles in Poland has a long tradition, yet due to some historical aspects, this knowledge was lost. Currently, truffles and truffle orchards are again receiving attention, and thanks to, e.g., historical data, they have solid foundations to be established. Publications relating to truffles between 1661 and 2017 were searched for in international and national databases, such as the database of PhD theses, Google Scholar, and catalogues of the National Library of Poland, the Jagiellonian Digital Library, the University Library of J. Giedroyc in Bialystok and the Lower Silesian Digital Library (DBC). A very meticulous survey of the literature on truffles showed that truffles have been known since at least 1661. In the 18th century, the fungi were considered a non-timber forest product. It is interesting to mention the impact of Polish Count Michał Jan Borch in understanding the nature of truffles. The whitish truffle (Tuber borchii) is named after him. The greatest number of publications regarding truffles can be observed at the first half of the 19th and 20th centuries. The fungi were present not only in cookbooks but also in scientific literature, and aspects of their ecology and medicinal use are considered. The "dark ages" for truffles, mainly for social reasons, occurred after the Second World War. In tough times, when Poland was under Soviet communist control (1945-1989), truffles as a luxurious product have been completely forgotten. However, at the end of the 20th century, truffles started receiving attention in Polish society. Yet, the real awakening began in the first decade of the twenty-first century when the first truffle orchards were established. One of them has already produced the first fruit bodies of summer truffle (Tuber aestivum). Truffles have been present in Polish culture for centuries. Their renaissance indicates the need for fostering sustainable agroforestry-centred initiatives aimed at helping truffle growers in growing the

Pediculosis seems to have afflicted humans since the most ancient times and lice have been found in several ancient human remains. Examination of the head hair and pubic hair of the artificial mummy of Ferdinand II of Aragon (1467-1496), King of Naples, revealed a double infestation with two different species of lice, Pediculus capitis, the head louse, and Pthirus pubis, the pubic louse. The hair samples were also positive for the presence of mercury, probably applied as an anti-pediculosis therapy. This is the first time that these parasites have been found in the hair of a king, demonstrating that even members of the wealthy classes in the Renaissance were subject to louse infestation.

Nuclear power: renaissance or relapse? Global climate change and long-term Three Mile Island activists' narratives.

Community narratives are increasingly important as people move towards an ecologically sustainable society. Global climate change is a multi-faceted problem with multiple stakeholders. The voices of affected communities must be heard as we make decisions of global significance. We document the narratives of long-term anti-nuclear activists near the Three Mile Island (TMI) nuclear power plant who speak out in the dawn of a nuclear renaissance/relapse. While nuclear power is marketed as a "green" solution to global warming, their narratives reveal three areas for consideration; (1) significant problems with nuclear technology, (2) lessons "not" learned from the TMI disaster, and (3) hopes for a sustainable future. Nuclear waste, untrustworthy officials and economic issues were among the problems cited. Deceptive shaping of public opinion, nuclear illiteracy, and an aging anti-nuclear movement were reasons cited for the lessons not learned. However, many remain optimistic and envision increased participation to create an ecologically-balanced world.

Italian medieval and Renaissance manuscript cuttings and miniatures from the Victoria and Albert Museum were analyzed by Raman microscopy to compile a database of pigments used in different periods and different Italian regions. The palette identified in most manuscripts and cuttings was found to include lead white, gypsum, azurite, lazurite, indigo, malachite, vermilion, red lead, lead tin yellow (I), goethite, carbon, and iron gall ink. A few of the miniatures, such as the historiated capital “M” painted by Gerolamo da Cremona and the Petrarca manuscript by Bartolomeo Sanvito, are of exceptional quality and were analyzed extensively; some contained unusual materials. The widespread usage of iron oxides such as goethite and hematite as minor components of mixtures with azurite is particularly notable. The use of a needle-shaped form of iron gall ink as a pigment rather than a writing material was established by both Raman microscopy and x-ray fluorescence spectroscopy for the Madonna and Child by Franco de’ Russi.

Lustre is known as one of the most significant decorative techniques of Medieval and Renaissance pottery in the Mediterranean basin, characterized by brilliant gold and red metallic reflections and iridescence effects. Previous studies by various techniques (SEM-EDS and TEM, UV-VIS, XRF, RBS and EXAFS) demonstrated that lustre consists of a heterogeneous metal-glass composite film, formed by Cu and Ag nanoparticles dispersed within the outer layer of a tin-opacified lead glaze. In the present work the investigation of an original gold lustre sample from Deruta has been carried out by means of glancing-incidence X-ray diffraction techniques (GIXRD). The study was aimed at providing information on structure and depth distribution of Ag nanoparticles. Exploiting the capability of controlling X-ray penetration in the glaze by changing the incidence angle, we used GIXRD measurements to estimate non-destructively thickness and depth of silver particles present in the first layers of the glaze.

Padovani, S.; Borgia, I.; Brunetti, B.; Sgamellotti, A.; Giulivi, A.; D'Acapito, F.; Mazzoldi, P.; Sada, C.; Battaglin, G.

Lustre is one of the most important decorative techniques of the Medieval and Renaissance pottery of the Mediterranean basin, capable of producing brilliant metallic reflections and iridescence. Following the recent finding that the colour of lustre decorations is mainly determined by copper and silver nanoclusters dispersed in the glaze layer, the local environment of copper and silver atoms has been studied by extended X-ray absorption fine structure (EXAFS) spectroscopy on original samples of gold and red lustre. It has been found that, in gold lustre, whose colour is attributed mainly to the silver nanocluster dispersion, silver is only partially present in the metallic form and copper is almost completely oxidised. In the red lustre, whose colour is attributed mainly to the copper nanocluster dispersion, only a fraction of copper is present in the metallic form. EXAFS measurements on red lustre, carried out in the total electron yield mode to probe only the first 150 nm of the glaze layer, indicated that in some cases lustre nanoclusters may be confined in a very thin layer close to the surface.

The 21st century psychedelic renaissance: heroic steps forward on the back of an elephant.

2018-02-01

Given the plethora of new studies and published papers in the scientific press and the increasingly emerging presence of articles about positive psychedelic experiences appearing in the popular media, there is little doubt that we are in the midst of a Psychedelic Renaissance. The classical psychedelic drugs LSD and psilocybin and the entactogen MDMA are showing promise as tools to assist psychotherapy for a wide range of mental disorders, with multiple pilot studies demonstrating their safety and efficacy. In this article, the author describes how MDMA in particular has inherent characteristics that make it well suited for assisting trauma-focused psychotherapy in a population of patients who have experienced child abuse. But despite these advances, there remain many obstacles ahead of the widespread mainstream acceptance of psychedelic medicines. The author argues that the Misuse of Drugs Act 1971 is one such obstacle. Other impediments include a prevailing attitude of pseudoscience and rigidity from within the non-scientific psychedelic community itself. Resolution of these conflicts must be sought if medicine and society are to see psychedelics gaining a place in mainstream culture and science.

The Life of a Renaissance Gunmaker: Bonaccorso Ghiberti and the Development of Florentine Artillery in the Late Fifteenth Century.

Ansani, Fabrizio

This article examines the technological development of artillery production in Florence during the last two decades of the fifteenth century, before and after the assimilation of the most efficient French ordnance into Italian warfare. The study starts from the notes, drawings, accounts, and guns produced by Bonaccorso di Vettorio Ghiberti (1451-1516), the heir of the foundry of his illustrious ancestor Lorenzo di Cione (1378-1455). Data have been collected from the historical archives of the Istituto degli Innocenti, from the Biblioteca Nazionale Centrale of Florence, and from the Florentine State Archive. This article demonstrates the existence of a lively and reactive war-related industry in Renaissance Italy, which was aware of new ideas and new techniques. The article highlights, moreover, the leading role of public demand in fostering military innovations.

Paracelsus and the science of nutrition in the renaissance. On occasion of the 500th anniversary of his birth.

PubMed

Guggenheim, K Y

1993-07-01

Paracelsus (1493-1541) was a Swiss chemist and physician. As professor of medicine in Basel, he violently opposed traditional Galenic medicine and emphasized direct observation instead. His nonconformist views and rough behaviour led to his expulsion after less than a year. He led an itinerant life, practicing medicine, writing books and studying diseases of miners. Paracelcus believed in an immaterial principle, the "alchemist," that converted food into body substance. Every animal species, he believed, was endowed with its own alchemist, adapted to its needs. Paracelcus introduced chemical thinking into medicine (iatrochemistry) and nutrition. Today, he remains a controversial figure. Other Renaissance scientists (Fernel, Vesalius) criticized traditional medicine without completely rejecting it. Leonardo da Vinci developed original views on nutrition, based on his anatomical studies. His views were, however, without influence, because he did not publish.

On kissing and sighing: Renaissance homoerotic love from Ficino's De Amore and Sopra Lo Amore to Cesare Trevisani's L'impresa (1569).

Maggi, Armando

2005-01-01

This essay investigates the homoerotic connotations present in the so-called treatises on love, a popular philosophical and literary genre of the Italian Renaissance. The referential text of this sixteenth- century genre is Marsilio Ficino's De amore (1484), a deeply innovative interpretation of Plato's Symposium. Focusing on the initial section of Ficino's text, Maggi highlights some important structural differences between the De amore and the Symposium. Moreover, by comparing Ficino's Latin text with his own subsequent Italian translation (Sopra lo amore, 1544), Maggi examines how Ficino interprets some key terms such as appearance and splendor. The second part of the essay studies Cesare Trevisani's L'impresa (1569), a later treatise on love with an explicit homoerotic foundation.

Art and anatomy were particularly closely intertwined during the Renaissance period and numerous painters and sculptors expressed themselves in both fields. Among them was Michelangelo Buonarroti (1475-1564), who is renowned for having produced some of the most famous of all works of art, the frescoes on the ceiling and on the wall behind the altar of the Sistine Chapel in Rome. Recently, a unique association was discovered between one of Michelangelo's most celebrated works (The Creation of Adam fresco) and the Divine Proportion/Golden Ratio (GR) (1.6). The GR can be found not only in natural phenomena but also in a variety of human-made objects and works of art. Here, using Image-Pro Plus 6.0 software, we present mathematical evidence that Michelangelo also used the GR when he painted Saint Bartholomew in the fresco of The Last Judgment, which is on the wall behind the altar. This discovery will add a new dimension to understanding the great works of Michelangelo Buonarroti. © 2015 Wiley Periodicals, Inc.

The Golden Beauty: Brain Response to Classical and Renaissance Sculptures

Is there an objective, biological basis for the experience of beauty in art? Or is aesthetic experience entirely subjective? Using fMRI technique, we addressed this question by presenting viewers, naïve to art criticism, with images of masterpieces of Classical and Renaissance sculpture. Employing proportion as the independent variable, we produced two sets of stimuli: one composed of images of original sculptures; the other of a modified version of the same images. The stimuli were presented in three conditions: observation, aesthetic judgment, and proportion judgment. In the observation condition, the viewers were required to observe the images with the same mind-set as if they were in a museum. In the other two conditions they were required to give an aesthetic or proportion judgment on the same images. Two types of analyses were carried out: one which contrasted brain response to the canonical and the modified sculptures, and one which contrasted beautiful vs. ugly sculptures as judged by each volunteer. The most striking result was that the observation of original sculptures, relative to the modified ones, produced activation of the right insula as well as of some lateral and medial cortical areas (lateral occipital gyrus, precuneus and prefrontal areas). The activation of the insula was particularly strong during the observation condition. Most interestingly, when volunteers were required to give an overt aesthetic judgment, the images judged as beautiful selectively activated the right amygdala, relative to those judged as ugly. We conclude that, in observers naïve to art criticism, the sense of beauty is mediated by two non-mutually exclusive processes: one based on a joint activation of sets of cortical neurons, triggered by parameters intrinsic to the stimuli, and the insula (objective beauty); the other based on the activation of the amygdala, driven by one's own emotional experiences (subjective beauty).

Production of gold and ruby-red lustres in Gubbio (Umbria, Italy) during the Renaissance period

NASA Astrophysics Data System (ADS)

Padeletti, G.; Fermo, P.

The aim of this work is to gain a further insight into the knowledge of the production process of lustre-decorated ancient majolicas. Lustre is a sophisticated technique employed in the decoration of majolicas as used in central Italy during the Renaissance period. It consists of a beautiful iridescent gold or ruby-red thin metallic film, containing silver, copper and other substances and obtained in a reducing atmosphere on a previously glazed ceramic. Nowadays, it is not possible to replicate the outstanding results obtained by the ancient ceramicists, since the original recipes were lost. It is quite interesting to study lustre-production technology by means of analytical techniques now employed for advanced research on materials (XRD, ETAAS, ICP-OES, TEM-EDX-SAED and UV-Vis). In this work, we have focussed our attention on ceramic fragments decorated with both gold and ruby-red lustres, which were difficult to obtain due to complex reduction conditions required and which were a prerogative of Gubbio production. The two lustre colours differ in their chemical composition as well in their nanostructure. The presence of bismuth was disclosed and it was ascertained to be a distinctive feature of the Italian production.

In recent years, increasing numbers of people have been choosing herbal medicines or products to improve their health conditions, either alone or in combination with others. Herbs are staging a comeback and herbal "renaissance" occurs all over the world. According to the World Health Organization, 75% of the world's populations are using herbs for basic healthcare needs. Since the dawn of mankind, in fact, the use of herbs/plants has offered an effective medicine for the treatment of illnesses. Moreover, many conventional/pharmaceutical drugs are derived directly from both nature and traditional remedies distributed around the world. Up to now, the practice of herbal medicine entails the use of more than 53,000 species, and a number of these are facing the threat of extinction due to overexploitation. This paper aims to provide a review of the history and status quo of Chinese, Indian, and Arabic herbal medicines in terms of their significant contribution to the health promotion in present-day over-populated and aging societies. Attention will be focused on the depletion of plant resources on earth in meeting the increasing demand for herbs.

Symmetry and asymmetry in aesthetics and the arts

NASA Astrophysics Data System (ADS)

McManus, I. C.

2005-10-01

Symmetry and beauty are often claimed to be linked, particularly by mathematicians and scientists. However philosophers and art historians seem generally agreed that although symmetry is indeed attractive, there is also a somewhat sterile rigidity about it, which can make it less attractive than the more dynamic, less predictable beauty associated with asymmetry. Although a little asymmetry can be beautiful, an excess merely results in chaos. As Adorno suggested, asymmetry probably results most effectively in beauty when the underlying symmetry upon which it is built is still apparent. This paper examines the ways in which asymmetries, particularly left-right asymmetries, were used by painters in the Italian Renaissance. Polyptychs often show occasional asymmetries, which are more likely to involve the substitution of a left cheek for a right cheek, than vice-versa. A hypothesis is developed that the left and right cheeks have symbolic meanings, with the right cheek meaning "like self" and the left cheek meaning "unlike self". This principle is evaluated in pictures such as the Crucifixion, the Annunciation and, the Madonna and Child. The latter is particularly useful because the theological status of the Madonna changed during the Renaissance, and her left-right portrayal also changed at the same time in a comprehensible way. Some brief experimental tests of the hypothesis are also described. Finally the paper ends by considering why it is that the left rather than the right cheek is associated with "unlike self", and puts that result in the context of the universal "dual symbolic classification" of right and left, which was first described by the anthropologist Robert Hertz.

Idiopathic clubfoot is one of the most common problems in paediatric orthopaedics. The treatment is controversial and continues to be one of the challenges in paediatric orthopaedics. The aim of this review is to assess the different methods of clubfoot treatment used over the years in light of the documentation present in the literature and art paintings from the antiquity to the end of the 19th century. The aim of this paper is to review all treatment methods of the clubfoot over the years that were proposed to provide patients a functional, pain-free, normal-looking foot, with good mobility, without calluses, and requiring no special shoes. Hippocrates was the first to write references about treatment methods of clubfoot. After the Middle Ages and the Renaissance where patients were treated by barber-surgeons, quacks and charlatans, bonesetters, and trussmakers, there were more detailed studies on the disease, with the help of famous names in medicine such as Venel and Scarpa.

The rise and fall of the autochthonous self: from Italian Renaissance art and Shakespeare to Heidegger, Lacan, and intersubjectivism.

PubMed

Chessick, Richard D

2010-01-01

This article addresses the unresolved question of the existence of a private core autochthonous self, as it has been described by Winnicott, Modell, and others. The postmodern version of the self has eliminated this concept entirely, relegating the self to a changing and unstable display, or regarding it as totally chaotic, or even an illusion. The question is raised whether by returning to the origins of this notion of a private self and then tracing its apparent dissolution it might be possible to discover some evidence that it still exists. The methodology used is that of obtaining knowledge directly through the arts and the claim is made that because empirical science has clamored to be the only source of knowledge, we have lost what could be obtained by direct intuitive seeing and experiencing the works of creative geniuses. To explore the rise of the autochthonous self this article provides an examination of the shift from Gothic art to Italian Renaissance art, a time which engendered the origin of "man" with his or her elusive private individual self that then became expressed in changing works of art. As this spread north, Shakespeare appeared and similarly invented and illustrated in his characters the private individual self, a concept not appreciated or recognized before the renaissance. But as science arose and Western civilization began to decline, a corresponding disillusionment with "man" took place. The self began to be viewed as solely a social construction with no core except perhaps a genetic endowment. This was accompanied by a reduction in the concept of the human as a valuable and precious living being and was replaced by regarding the human as an object of control and exploitation. After the Second World War a movement in contemporary United States psychoanalysis gradually replaced the ideas of Freud and his emphasis on the "I" in the psychoanalytic process, with forms of relational therapy, assuming that the self was ab initio

Martín-Araguz, A; Bustamante-Martínez, C

The Spanish renaissance doctor Juan Huarte de San Juan (1529-1588) was the author of a unique and immortal work, The Examination of Men's Wits, the edition princeps of which was printed in Baeza in 1575. Since then it has been reprinted at least 80 times and translated into seven languages, which makes it the most influential Spanish contribution to medicine ever published. In this paper we review the unjustly little-known figure of Huarte as the founder of Neuropsychology, and we also analyse his works from a historical and neuroscientific point of view. Huarte's writings deal with the problem of the organic relations between the brain and understanding, and accept the possible influences exerted by temper on the will within the field of the Neurobiology of Intelligence. Thus, over four centuries ago Huarte became the founder of Differential or Physiological Psychology, Neuropsychology, Eugenics and Career Guidance. Huarte's work not only played a fundamental role in the history and development of the body of neuroscientific knowledge, but has also been a clear (although not always cited) influence on scientists, philosophers and men of letters such as Alarcón, Bacon, Cabanis, Cervantes (whose Don Quixote was inspired by him), Charron, Chomsky, Gall, Goethe, Hume, Kant, Kretchmer, Lessing, Lope de Vega, Montaigne, Montesquieu, Nietzsche, Quevedo, Rousseau, Schopenhauer, Thomasius, Tirso de Molina and Ziegler. In the middle of the 16th century, Huarte and his Examination of Men's Wits, together with the works of the naturalist philosophers Gómez Pereira (Antoniana Margarita, 1554) and Miguel Sabuco (New Philosophy, 1587), constituted the prestigious triumvirate of Spanish Renaissance scholars who, for the first time in history, contemplated the workings of the brain from a point of view that had more to do with science than the supernatural.

However, it is not possible to obtain information concerning the quantity of organic binder. Backscattering spectrometry (BS) can be a useful complementary method to overcome this limitation. In the case of paint layers, PIXE brings the elemental composition (major elements to traces) and the BS spectrum can give access to the proportion of pigment and binder. With the use of 3 MeV protons for PIXE and BS simultaneously, it was possible to perform quantitative analysis including C and O for which the non-Rutherford cross sections are intense. Furthermore, with the use of the same conditions for PIXE and BS, the experiment time and the potential damage by the ion beam were reduced. The results obtained with the external beam of the Accélérateur Grand Louvre pour l'Analyse Elementaire (AGLAE) facility on various test painting samples and on cross sections from Italian Renaissance masterpieces are shown. Simultaneous combination of PIXE and BS leads to a complete characterization of the paint layers: elemental composition and proportion of the organic binder have been determined and thus provide useful information about ancient oil painting recipes.

In this paper, three Renaissance tapestries depicting scenes painted by Raffaello Sanzio, conserved at the Vatican Museum, were investigated using in-situ UV-Visible fluorimetric measurements. The results show that this technique is suitable for the detection of natural organic colorants used for dyeing the threads woven in these tapestries. The emission signals detected on red-purple colours were assigned to the colorant orcein and those on different nuances of blue and green colours to indigo by comparison with data from reference laboratory samples. The assignments were supported by chromatographic experiments carried out on threads taken from the back side of the tapestry in the same points analysed by spectrofluorimentry.

We present synthetic observations for the first generations of galaxies in the Universe and make predictions for future deep field observations for redshifts greater than 6. Due to the strong impact of nebular emission lines and the relatively compact scale of H II regions, high-resolution cosmological simulations and a robust suite of analysis tools are required to properly simulate spectra. We created a software pipeline consisting of fsps, hyperion, cloudy and our own tools to generate synthetic IR observations from a fully three-dimensional arrangement of gas, dust, and stars. Our prescription allows us to include emission lines for a complete chemical network and tackle the effect of dust extinction and scattering in the various lines of sight. We provide spectra, 2D binned photon imagery for both HST and JWST IR filters, luminosity relationships, and emission-line strengths for a large sample of high-redshift galaxies in the Renaissance Simulations. Our resulting synthetic spectra show high variability between galactic haloes with a strong dependence on stellar mass, metallicity, gas mass fraction, and formation history. Haloes with the lowest stellar mass have the greatest variability in [O III]/Hβ, [O III], and C III], while haloes with higher masses are seen to show consistency in their spectra and [O III] equivalent widths between 1 and 10 Å. Viewing angle accounted for threefold difference in flux due to the presence of ionized gas channels in a halo. Furthermore, JWST colour plots show a discernible relationship between redshift, colour, and mean stellar age.

Style and non-style in anatomical illustration: From Renaissance Humanism to Henry Gray.

PubMed

Kemp, Martin

2010-02-01

Style is a familiar category for the analysis of art. It is less so in the history of anatomical illustration. The great Renaissance and Baroque picture books of anatomy illustrated with stylish woodcuts and engravings, such as those by Charles Estienne, Andreas Vesalius and Govard Bidloo, showed figures in dramatic action in keeping with philosophical and theological ideas about human nature. Parallels can be found in paintings of the period, such as those by Titian, Michelangelo and Hans Baldung Grien. The anatomists also claimed to portray the body in an objective manner, and showed themselves as heroes of the discovery of human knowledge. Rembrandt's painting of Dr Nicholas Tulp is the best-known image of the anatomist as hero. The British empirical tradition in the 18th century saw William Cheselden and William Hunter working with techniques of representation that were intended to guarantee detailed realism. The ambition to portray forms life-size led to massive volumes, such as those by Antonio Mascagni. John Bell, the Scottish anatomist, criticized the size and pretensions of the earlier books and argued for a plain style adapted to the needs of teaching and surgery. Henry Gray's famous Anatomy of 1858, illustrated by Henry Vandyke Carter, aspired to a simple descriptive mode of functional representation that avoided stylishness, resulting in a style of its own. Successive editions of Gray progressively saw the replacement of Gray's method and of all his illustrations. The 150th anniversary edition, edited by Susan Standring, radically re-thinks the role of Gray's book within the teaching of medicine.

Standard anthropometric measurements that determine the facial canons were made on these 3-D images. The validity of the canons as well as their different variants were quantified. The neoclassical cannons seldom applied to these individuals, and facial three-section and orbital canons did not apply at all. The orbitonasal canon was most frequently applicable, with a frequency of 19%. Significant sexual dimorphism was found relative to the prevalence of the variants of facial three-section and orbitonasal canons. The neoclassical canons did not appear to apply to our sample when rigorous quantitative measurements were employed. Thus, they should not be used as esthetic goals for craniofacial surgical interventions.

For the first time some excellent pieces belonging to the majolica production of the great master Giorgio Andreoli from Gubbio (Central Italy) have been characterized from a chemical and structural point of view with the aim to identify the composition of both pigments and lustres. A series of particle-induced X-ray emission (PIXE), Rutherford backscattering spectrometry (RBS) and Raman analyses have been performed on some plates coming from Museo del Palazzo dei Consoli (Gubbio) and several French museums (Louvre, Musée National de la Céramique, Musée National de la Renaissance) lustred by Giorgio Andreoli and decorated by famous majolica painters such as Francesco Xanto Avelli. The three techniques are complementary and useful in the investigation of art objects since they are non-destructive. Furthermore, the low detection limits allow the identification of all elements and compounds present, and RBS allows concentration profiling, too. It is worth noticing that the examined objects are characterized by the presence of both gold and ruby-red lustres, a peculiarity of Mastro Giorgio’s technique. The measurements by PIXE and RBS have been carried out on the AGLAE accelerator at C2RMF, Louvre Palace.

Italian Renaissance and Hispano-Moresque lustre-decorated majolicas: imitation cases of Hispano-Moresque style in central Italy

NASA Astrophysics Data System (ADS)

Padeletti, G.; Fermo, P.

An investigation was carried out on Renaissance lustre-decorated majolica shards, found during excavations made in Umbria (central Italy) and defined by experts, on the ground of the surface decoration, as imitations of the Hispano-Moresque style. A comparison between this particular kind of samples, produced in central Italy, and some Hispano-Moresque lustre shards has been performed. The ceramic bodies as well as the lustred surfaces have been analysed by means of several techniques: inductively coupled plasma optical emission spectrometry, X-ray diffraction (XRD), atomic absorption spectrometry with electrothermal atomisation and scanning electron microscopy. By means of XRD analysis the presence of cosalite (Pb2Bi2S5) has been disclosed in the Italian lustre decorations but was not observed in the Hispano-Moresque ones. A hypothesis has been made, considering bismuth as a discriminating element, between lustres produced in central Italy and the Hispano-Moresque ones. We thought that the Italian artisans were able to manage the use of bismuth. Therefore a recipe, quite similar to the one employed by the Spanish artisans, was used by the Italian ceramists if their aim was to imitate the Hispano-Moresque style.

The contribution of intellectuals to the history of traumatology during the Renaissance: treatment of femoral fracture through François Rabelais' glossocomion.

2017-02-01

During the Middle Ages and the Renaissance, intellectuals often included clinical cases and medical descriptions in their literary works. These authors appeared to be more interested in internal and infectious diseases rather than in musculoskeletal disorders and orthopaedics. François Rabelais (1490-1553) was one of the most renowned humanists and philologists of the sixteenth century. He was also a physician with an interest in translating ancient texts of medical authors. Rabelais rediscovered a device for treating femoral fracture originally described by the Roman physician Galen and named as glossocomion. Since the original apparatus had some imperfections, Rabelais redesigned and modified it. This new, improved version became a model for new devices for treating femoral fracture, as also reported by the great French surgeon Ambroise Paré. For this contribution, Rabelais deserves major consideration in the history of orthopaedics and traumatology.

Lusters of renaissance pottery: Experimental and theoretical optical properties using inhomogeneous theories

Luster decoration of medieval and renaissance potteries constitutes one of the most important and sophisticated decoration techniques of the Mediterranean basin. Lusters consist in a thin layer of silver and copper nanocrystals immersed in a dielectric matrix. Different physical phenomena are responsible for the very brilliant and complex colored effect produced by the lusters. On one hand, according to the thickness of the thin layer, interferential effects occur giving rise to a classical iridescent effect. On the other hand, the nanostructure of the metallic compound leads to extra absorption, generally observed in the visible or near infrared, due to an external resonance associated with the excitation of a surface plasmon in the metallic particles. The position of this resonance, and so the color of the film, depends from many parameters, mainly: (1) the relative volume fraction p of the metal inclusions. (2) The mean size of the metal particle. (3) The shape of the particles and (4) the dielectric functions of the constituents. These two phenomena are not independent as the second one greatly affects the dielectric function of the film and, thus, its optical thickness. In this paper, the physical and optical properties of various lusters from Deruta and Gubbio (Italy) of the XVI century are presented. The structure and the composition of the different films have been determined by scanning electron microscope (SEM), ion beam analyses (PIXE and RBS) and low incidence X-ray diffraction. The optical properties have been determined by two different techniques: (a) hemispherical spectroscopic measurements under near-normal incidence; (b) gonioscopic measurements for a given angle of incidence and wavelength. The first one allows the determination of the effective index of refraction of the inhomogeneous layer, and the second one the determination of the bidirectional reflectance distribution function (BRDF) of the material.

A Third Note: Helmholtz, Palestrina, and the Early History of Musicology.

PubMed

Kursell, Julia

2015-06-01

This contribution focuses on Hermann von Helmholtz's work on Renaissance composer Giovanni Pierluigi da Palestrina. Helmholtz used his scientific concept of distortion to analyze this music and, reversely, to find corroboration for the concept in his musical analyses. In this, his work interlocked with nineteenth-century aesthetic and scholarly ideals. His eagerness to use the latest products of historical scholarship in early music reveals a specific view of music history. Historical documents of music provide the opportunity for the discovery of new experimental research topics and thereby also reveal insights into hearing under different conditions. The essay argues that this work occupies a peculiar position in the history of musicology; it falls under the header of "systematic musicology," which eventually emerged as a discipline of musicology at the end of the nineteenth century. That this discipline has a history at all is easily overlooked, as many of its contributors were scientists with an interest in music. A history of musicology therefore must consider at least the following two caveats: parts of it take place outside the institutionalized field of musicology, and any history of musicology must, in the last instance, be embedded in a history of music.

Daniell, W.E.

The possibility that previous occupational exposure to solvents might be associated with clinically significant neurological dysfunction in older adults was investigated in a cross-sectional study. Subjects included 67 painters, 22 aerospace painters and fuel cell sealers, and a comparison group of 126 carpenters. All subjects had retired from regular employment at least 1 year prior to the study. As measured by semiquantitative exposure index, the cumulative histories of lifetime occupational solvent exposure were on the average comparable in the two exposed study groups, painters and aerospace workers. The carpenters differed from the other groups in solvent exposure by several ordersmore » of magnitude. The painters had a significantly higher history of consuming alcoholic beverages than did the other two study groups. The painters had a significantly higher score on the Beck Depression Inventory, a measure of current depressive symptoms. The painters reported significantly more general neurologic symptoms than did the other two groups. The aerospace workers showed much greater evidence of possible adverse effects from former solvent exposure on current neuropsychological function than did the painters when determined by reasoning and memory tests, memory visual motor speed and motor tests. No evidence of persistent effects on liver or renal excretory function was seen in solvent exposed subjects.« less

From a Point Cloud Survey to a Mass 3d Modelling: Renaissance Hbim in Poggio a Caiano

This paper introduces some studies developed regarding the Medicea Villa at Poggio a Caiano, in Italy. The monumental building was built by Lorenzo de' Medici and his heirs following the design of the famous architect Giuliano da Sangallo, between 1485 and 1520. The Villa embodies many of the typical features of the Italian Renaissance, added a monumental double circular stairway in the front façade during neoclassical times, heading to the upper balcony surrounded by a balustrade. The Villa was surveyed taking advantage of Terrestrial Laser Scanning and Digital Photogrammetry, in order to produce a detailed model to be translated into a HBIM digital prototype then. The Scan-to-BIM approach was obtained with a generation of semantics and components proper of Sangallo's architectural grammar, first of all defining the object, then geometry, and then their parametrization. This process led to a model of the exteriors, used to better understand the architectural composition of the volumes, to make some hypothesis on its shape according to the original architect's drawing in the Taccuino Senese, on its general structural behaviours, to understand the limits of a process and the perspective of a research that goes from a digital survey to the HBIM environment.

How the masters in Umbria, Italy, generated and used nanoparticles in art fabrication during the Renaissance period

NASA Astrophysics Data System (ADS)

Padeletti, G.; Fermo, P.

Lustre was one of the most sophisticated techniques for the decoration of majolicas during the Renaissance period. Lustre consists of a thin metallic film containing silver, copper and other substances like iron oxide and cinnabar applied in a reducing atmosphere on a previously glazed ceramic. In this way, beautiful iridescent reflections of different colours (in particular gold and ruby-red) are obtained. The characterisation and the study of lustre-decorated majolicas is of great interest for archaeologists, but also offers possibilities for producing pottery with outstanding decoration today, following ancient examples, since nowadays Italian artisans are interested in the reproduction of the ancient recipes and procedures. Moreover, it can even suggest new procedures for obtaining uniform thin metallic films for technological applications. A study has been carried out on ancient lustre layers using numerous different analytical techniques such as XRD, SEM-EDX, TEM-EDX-SAED, ETAAS, ICP-OES, UV-vis reflectance spectroscopy and SAXS. Lustre films were shown to be formed by copper and silver clusters of nanometric dimension. The colour and the properties of the lustre films depend on the elemental composition of the impasto applied to the ceramic surface as well as on other factors like the metallic nanocluster dimension, the firing conditions, the underlying glaze composition and the procedure used.

A historical and metallurgical characterization of a "falchion" sword manufactured in Caino (Brescia, northern Italy) and dating from the early 17th century was performed to understand the manufacture methods of a Renaissance sword. At first, a set of size measurements was carried out to look for the existence of constant and/or recurring macroscopic sizes, which would indicate a standardized production, or of any type of proportionality between different parts of a sword, which would prove an intentional design activity. Light optical microscopy, scanning electron microscopy, energy-dispersive x-ray spectroscopy, quantometer analyses, and Vickers microhardness tests were then employed to analyze the microstructure and obtain the mechanical properties. All the metallurgical work is supported by an accurate study on the chemical composition of both metal-matrix and nonmetallic inclusions, which allowed for rebuilding and evaluating the efficiency of the whole production process.

Moon-Struck: Artists Rediscover Nature And Observe

NASA Astrophysics Data System (ADS)

Pasachoff, Jay M.; Olson, Roberta J. M.

We discuss rare early depictions of the Moon by artists who actually observed Earth's nearest neighbor rather than relying on stylized formulas. The earliest, from the 14th and 15th centuries, reveal that revolutionary advances in both pre-telescopic astronomy and naturalistic painting could go hand-in-hand. This link suggests that when painters observed the world, their definition of world could also include the heavens and the Moon. Many of the artists we discuss - e.g., Pietro Lorenzetti, Giotto, and Jan Van Eyck - actually studied the Moon, incorporating their studies into several works. We also consider the star map on the dome over the altar in the Old Sacristy of San Lorenzo, Florence (c. 1442), whose likely advisor was Toscanelli. In addition, we examine representations by artists who painted for Popes Julius II and Leo X - Raphael and Sebastiano del Piombo, both of whom were influenced by individuals at the papal court, such as the astronomer, painter, and cartographer Johann (Giovanni) Ruysch and Leonardo da Vinci. We also discuss Leonardo's pre-telescopic notes and lunar drawings as they impacted on art and science in Florence, where Galileo would study perspective and chiaroscuro. Galileo's representations of the Moon (engraved in his Sidereus Nuncius, 1610) are noted, together with those by Harriot and Galileo's friend, the painter Cigoli. During the 17th century, the Moon's features were telescopically mapped by astronomers with repercussions in art, e.g., paintings by Donati Creti and Raimondo Manzini as well as Adam Elsheimer. Ending with a consideration of the 19th-century artists/astronomers John Russell and John Brett and early lunar photography, we demonstrate that artistic and scientific visual acuity belonged to the burgeoning empiricism of the 14th, 15th, and 16th centuries that eventually yielded modern observational astronomy.

Substantial exposure to isocyanates may occur during spray painting in autobody shops, yet information is lacking on the efficacy of the protective clothing used during spray painting. We investigated the personal and workplace factors associated with painters' dermal protection use during a large-scale exposure assessment study. Survey data indicated that 69% of painters always used gloves, with latex gloves (47%) and nitrile gloves (34%) used most frequently. Among latex glove users, 53% used thin latex (0.05-0.13 mm), 6% used medium latex (0.15-0.20 mm), and 12% used thick latex (> 0.20 mm). Among nitrile glove users, 27% used thin nitrile and 45% used medium nitrile. Sixty-three percent of painters always used coveralls, 44% preferring one particular brand. Although overspray presents an opportunity for dermal exposure to the neck and face, only 19% of painters protected these areas with personal protective equipment. Painters who always used coveralls were more likely to use gloves (odds ratio = 7.9, p = 0.061). Painters who reported ever having smoked cigarettes used gloves (p = 0.05) and coveralls (p = 0.04) more frequently. Painters who sprayed more than 34 clear coat jobs per month used coveralls most frequently (p = 0.038). Exact logistic regressions along with random sample calculations indicated that the survey results were independent of the shops. Because of the small sample size in this study, future research is warranted to corroborate these results. Studying the effectiveness of gloves and coveralls against polyurethane paints and understanding the underlying motivators and preferences for painters and business owners is needed for the development of best practices for the selection and use of dermal protection.

Task based exposure assessment in ergonomic epidemiology: a study of upper arm elevation in the jobs of machinists, car mechanics, and house painters

PubMed Central

Svendsen, S; Mathiassen, S; Bonde, J

2005-01-01

Aims: To explore the precision of task based estimates of upper arm elevation in three occupational groups, compared to direct measurements of job exposure. Methods: Male machinists (n = 26), car mechanics (n = 23), and house painters (n = 23) were studied. Whole day recordings of upper arm elevation were obtained for four consecutive working days, and associated task information was collected in diaries. For each individual, task based estimates of job exposure were calculated by weighting task exposures from a collective database by task proportions according to the diaries. These estimates were validated against directly measured job exposures using linear regression. The performance of the task based approach was expressed through the gain in precision of occupational group mean exposures that could be obtained by adding subjects with task based estimates to a group of subjects with measured job exposures in a "validation" design. Results: In all three occupations, tasks differed in mean exposure, and task proportions varied between individuals. Task based estimation proved inefficient, with squared correlation coefficients only occasionally exceeding 0.2 for the relation between task based and measured job exposures. Consequently, it was not possible to substantially improve the precision of an estimated group mean by including subjects whose job exposures were based on task information. Conclusions: Task based estimates of mechanical job exposure can be very imprecise, and only marginally better than estimates based on occupation. It is recommended that investigators in ergonomic epidemiology consider the prospects of task based exposure assessment carefully before placing resources at obtaining task information. Strategies disregarding tasks may be preferable in many cases. PMID:15613604

Considerations in Managing the Fill Rate of the Grand Ethiopian Renaissance Dam Reservoir Using a System Dynamics Approach.

Keith, Bruce; Ford, David N.; Horton, Radley M.

2016-01-01

The purpose of this study is to evaluate simulated fill rate scenarios for the Grand Ethiopian Renaissance Dam while taking into account plausible climate change outcomes for the Nile River Basin. The region lacks a comprehensive equitable water resource management strategy, which creates regional security concerns and future possible conflicts. We employ climate estimates from 33 general circulation models within a system dynamics model as a step in moving toward a feasible regional water resource management strategy. We find that annual reservoir fill rates of 8-15% are capable of building hydroelectric capacity in Ethiopia while concurrently ensuring a minimum level of stream flow disruption into Egypt before 2039. Insofar as climate change estimates suggest a modest average increase in stream flow into the Aswan, climate changes through 2039 are unlikely to affect the fill rate policies. However, larger fill rates will have a more detrimental effect on stream flow into the Aswan, particularly beyond a policy of 15%. While this study demonstrates that a technical solution for reservoir fill rates is feasible, the corresponding policy challenge is political. Implementation of water resource management strategies in the Nile River Basin specifically and Africa generally will necessitate a national and regional willingness to cooperate.

In this work some Renaissance lustre decorated ceramics have been examined. Our attention was directed to lustre which is a thin decorative metallic film applied on the surfaces of previously glazed ancient pottery. Some 16th century lustre ceramics shards from Deruta, Umbria (Italy) have been analysed by small angle X-ray scattering (SAXS) in order to characterise the dimension of the metal nanocrystals forming the thin lustre layer. This technique appeared to be a powerful tool to characterise lustre films nanostructure and may be successfully used for this purpose together with transmission electron microscopy (TEM). Furthermore, SAXS measurements are extremely suitable for the determination of polydispersity and average interparticle distance. The lustre surfaces have been also analysed by scanning electron microscopy plus X-ray energy dispersive spectrometry (SEM-EDX) in order to identify the metals present (silver, copper or both of them) and to establish copper/silver ratios. From the comparison between SAXS results and compositional data, it was possible to conclude that copper particles are smaller than the silver ones. We have evidenced how the microtexture as well as the chemical composition of the lustre layers are responsible for the gold or red colour typical of the lustre films.

The physiological challenges of the 1952 Copenhagen poliomyelitis epidemic and a renaissance in clinical respiratory physiology

PubMed Central

West, John B.

2005-01-01

The 1952 Copenhagen poliomyelitis epidemic provided extraordinary challenges in applied physiology. Over 300 patients developed respiratory paralysis within a few weeks, and the ventilator facilities at the infectious disease hospital were completely overwhelmed. The heroic solution was to call upon 200 medical students to provide round-the-clock manual ventilation using a rubber bag attached to a tracheostomy tube. Some patients were ventilated in this way for several weeks. A second challenge was to understand the gas exchange and acid-base status of these patients. At the onset of the epidemic, the only measurement routinely available in the hospital was the carbon dioxide concentration in the blood, and the high values were initially misinterpreted as a mysterious “alkalosis.” However, pH measurements were quickly instituted, the PCO2 was shown to be high, and modern clinical respiratory acid-base physiology was born. Taking a broader view, the problems highlighted by the epidemic underscored the gap between recent advances made by physiologists and their application to the clinical environment. However, the 1950s ushered in a renaissance in clinical respiratory physiology. In 1950 the coverage of respiratory physiology in textbooks was often woefully inadequate, but the decade saw major advances in topics such as mechanics and gas exchange. An important development was the translation of the new knowledge from departments of physiology to the clinical setting. In many respects, this period was therefore the beginning of modern clinical respiratory physiology. PMID:16020437

Anatomical knowledge among medieval folk artists: osteological interpretation of two Dance of Death motifs

Anatomy has a long history that started with dissection of animals and then expanded and flourished thanks to dissections performed on human bodies. Artists had a crucial role in uncovering the secrets of human anatomy. While most studies have focused on the influence of famous Renaissance artists on human anatomy studies, the anatomical drawings by pre-Renaissance artists and local craftsmen have remained in their shadow. One of the most popular artistic genres in which complete or parts of human skeletons appear is the Dance of Death (Danse Macabre). This article is an anthropological study of two medieval Dance of Death frescoes that are unusual in being relatively early as well as accurately datable. A comparative morphological analysis of the two late 15th century works present in Istria has been conducted. The two works were painted by two local masters and show how the artists filled the gaps in their knowledge of human anatomy mostly with insights into animal bones and imagination. Their artworks, even though only 16 years apart, demonstrate substantial differences in the representation of the skeletons. The article argues that the history of medicine and of art could make good use of osteology and physical anthropology in attempts to define and understand how anatomical knowledge developed among pre-Renaissance and post-Renaissance artists and local people.

The hair samples of Ferdinand II of Aragon (1467–1496), King of Naples, whose mummy is preserved in the Basilica of San Domenico Maggiore in Naples, showed a high content of mercury, with a value of 827ppm. Furthermore, examination using a stereomicroscope and a scanning electron microscope (SEM) of head and pubic hairs of Ferdinand II, revealed a lice infestation. The reasons for the massive presence of the mercury in the king's hair are discussed and contemporary literature regarding the use of this metal in medical therapies and in cosmetic practices is analysed. As a result, the high value of mercury in the hair of Ferdinand II can be attributed to antipediculosis therapy, applied as a topic medicament. This case represents an important finding for the history of medicine, because demonstrates that in the Renaissance mercury was applied locally not only to treat syphilis, as well attested by direct and indirect sources, but also to prevent or eliminate lice infestation.

Medieval and Renaissance anatomists: the printing and unauthorized copying of illustrations, and the dissemination of ideas.

PubMed

Lanska, Douglas J; Lanska, John Robert

2013-01-01

The vanguard that began to question Galenic anatomical dogma originated in northern Italy in the latter half of the thirteenth century, and not coincidentally this was where human dissection was introduced, which in turn eventually fostered the origins of realistic anatomical illustration in the late fifteenth century. With the advent of the printing press and moveable type at this time, printed books began to supersede hand-copied medieval manuscripts, and labor-intensive techniques were soon developed to integrate text and illustrations on the printed page. The same technology was used to pirate the illustrations of prior authors with varying fidelity. Specific medieval and Renaissance anatomical illustrations can often be traced from their inceptions through different stages of development to the final printed images, and then through subsequent pirated versions in various abridgements or other compendia. The most important milestone in the development of anatomy and anatomical illustration was the publication in 1543 by Andreas Vesalii of De humani corporis fabrica (On the Fabric of the Human Body), commonly referred to simply as the Fabrica. With this work, Vesalii succeeded in coordinating a publication production team (author, artists, block cutters, publisher, and typesetters) to achieve an unprecedented integration of scientific discourse, medical illustration, and typography. However, despite Vesalii's valiant efforts to prevent unauthorized duplication, the illustrations from the Fabrica were extensively plagiarized. Although Vesalii found such piracy frustrating and annoying, the long-term effect was to make Vesalii's ideas known to a wider readership and to help solidify his own revolutionary contributions to anatomy. © 2013 Elsevier B.V.

[Beginning, formative power and intellect agent of Nicolò Leoniceno between the Arabic-Latin tradition and the rebirth of the Greek commentators].

PubMed

Hirai, Hiro

2007-01-01

The treatise On Formative Power (Venice, 1506) of Ferrara's emblematic medical humanist, Nicolò Leoniceno (1428-1524), is the one of the first embryological monographs of the Renaissance. It shows, at the same time, the continuity of medieval Arabo-Latin tradition and the new elements brought by Renaissance medical humanism, namely through the use of the ancient Greek commentators of Aristotle like Simplicius. Thus this treatise stands at the crossroad of these two currents. The present study analyses the range of Leoniceno's philosophical discussion, determines its exact sources and brings to light premises for the early modern development of the concept of formative force, which will end up in the theory of "plastic nature" at the heart of the Scientific Revolution.

Contact x-ray therapy (CXRT) with 50 kV has proven to be an efficient radiation therapy technique to achieve local control and rectal preservation for early rectal adenocarcinoma. Despite these results, CXRT has not been used due to the shortage of the no longer manufactured Philips RT 50™ unit. Recently, a new CXRT machine (Papillon 50™) became available on the market. This machine delivers a beam of 50 kV with a dose rate close to 15 Gy/min and has a percentage depth dose of 50% at 6-7 mm. The applicator size varies from 2-3 cm in diameter. Due to the original design of the main tube, treatment delivery is quick and more comfortable for the patients. An online viewing system incorporated in the tube allows a good visualization of the tumor with improved accuracy of radiation delivery. An international collaborative trial (Contact Endoscopic Microsurgery [CONTEM]) was set up to accrue approximately 300 cases of rectal adenocarcinoma staged T1, T2 or early T3 tumors in the UK, France, Denmark and Sweden. This trial should confirm the role of CXRT in curative treatment with organ preservation for early rectal cancers.

A scientific approach to the attribution problem of renaissance ceramic productions based on chemical and mineralogical markers

NASA Astrophysics Data System (ADS)

Padeletti, G.; Fermo, P.

2010-09-01

Renaissance lustred majolica shards from Gubbio and Deruta (Central Italy) were investigated in order to point out differences in chemical and mineralogical composition between these two very similar Italian potteries and furthermore to find correlations with the local raw clay materials probably used for their production. Chemical and mineralogical analysis on the ceramic body were performed by ICP-OES (inductively coupled plasma optical emission spectroscopy) and XRD (X-ray diffraction), respectively. Investigation of the ceramic body revealed significant differences on calcium content indicating that it could be used as a marker for the two different productions. A separation of the ceramic shards in groups, on the base of their provenance, has been achieved applying to the data set formed by the chemical compositional data some multivariate techniques, such as PCA (principal component analysis) and HCA (hierarchical cluster analysis). Even the mineralogical composition of the groups shows very interesting features, differing Gubbio production from Deruta one for the presence of several mineralogical species. The investigations carried out on clays that were collected in the two geographical places have confirmed these differences. In fact, the clay materials have a chemical composition coherent with that one found in the shards. Firing tests performed by heating these clay in different conditions (temperature and soaking time) have shown a different behaviour as concerns the formation of the minerals and it is compatible with the shard composition found. From the comparison between the fired clay and the ceramic shards, some assumptions about the firing conditions applied by the ancient potters have been drawn.

Evolution of illustrations in anatomy: a study from the classical period in Europe to modern times.

PubMed

Ghosh, Sanjib Kumar

2015-01-01

Illustrations constitute an essential element of learning anatomy in modern times. However it required a significant evolutionary process spread over centuries, for illustrations to achieve the present status in the subject of anatomy. This review article attempts to outline the evolutionary process by highlighting on the works of esteemed anatomists in a chronological manner. Available literature suggests that illustrations were not used in anatomy during the classical period when the subject was dominated by the descriptive text of Galen. Guido da Vigevano was first to use illustrations in anatomy during the Late Middle Ages and this concept developed further during the Renaissance period when Andreas Vesalius pioneered in illustrations becoming an indispensable tool in conveying anatomical details. Toward later stages of the Renaissance period, Fabricius ab Aquapendente endeavored to restrict dramatization of anatomical illustrations which was a prevalent trend in early Renaissance. During the 18th century, anatomical artwork was characterized by the individual styles of prominent anatomists leading to suppression of anatomical details. In the 19th century, Henry Gray used illustrations in his anatomical masterpiece that focused on depicting anatomical structures and were free from any artistic style. From early part of the 20th century medical images and photographs started to complement traditional handmade anatomical illustrations. Computer technology and advanced software systems played a key role in the evolution of anatomical illustrations during the late 20th century resulting in new generation 3D image datasets that are being used in the 21st century in innovative formats for teaching and learning anatomy. © 2014 American Association of Anatomists.

Galaxy Properties and UV Escape Fractions during the Epoch of Reionization: Results from the Renaissance Simulations

2016-12-01

Cosmic reionization is thought to be primarily fueled by the first generations of galaxies. We examine their stellar and gaseous properties, focusing on the star formation rates and the escape of ionizing photons, as a function of halo mass, redshift, and environment using the full suite of the Renaissance Simulations with an eye to provide better inputs to global reionization simulations. This suite probes overdense, average, and underdense regions of the universe of several hundred comoving Mpc3, each yielding a sample of over 3000 halos in the mass range of 107-109.5 {M}⊙ at their final redshifts of 15, 12.5, and 8, respectively. In the process, we simulate the effects of radiative and supernova feedback from 5000 to 10,000 Population III stars in each simulation. We find that halos as small as 107 {M}⊙ are able to host bursty star formation due to metal-line cooling from earlier enrichment by massive Population III stars. Using our large sample, we find that the galaxy-halo occupation fraction drops from unity at virial masses above 108.5 {M}⊙ to ˜50% at 108 {M}⊙ and ˜10% at 107 {M}⊙ , quite independent of redshift and region. Their average ionizing escape fraction is ˜5% in the mass range of 108-109 {M}⊙ and increases with decreasing halo mass below this range, reaching 40%-60% at 107 {M}⊙ . Interestingly, we find that the escape fraction varies between 10%-20% in halos with virial masses of ˜3 × 109 {M}⊙ . Taken together, our results confirm the importance of the smallest galaxies as sources of ionizing radiation contributing to the reionization of the universe.

Ansel Adams: early works

2010-02-01

Ansel Adams (1902-1984), photographer, musician, naturalist, explorer, critic, and teacher, was a giant in the field of landscape photography. In his images of the unspoiled Western landscape, he strove to capture the sublime: the transcendentalist concept that nature can generate the experience of awe for the viewer. Many viewers are familiar with the heroic, high-contrast prints on high-gloss paper that Adams made to order beginning in the 1970s; much less well known are the intimate prints that the artist crafted earlier in his career. This exhibition focuses on these masterful small prints from the 1920s into the 1950s. During this time period, Adams's printing style changed dramatically. The painterly, soft-focus, warm-toned style of the Parmelian Prints of the High Sierras from the 1920s evolved into the sharp-focus style of the f/64 school of photography that Adams co-founded in the 1930s with Edward Weston and Imogen Cunningham. After World War II, Adams opted for a cooler, higher-contrast look for his prints. Throughout the various styles in which he chose to work, Adams explored the power of nature and succeeded in establishing landscape photography as a legitimate form of modern art.

PubMed

Lanthony, P

1991-01-01

The influence of color vision defects on pictorial art was studied using three methods. 1) From a theoretical standpoint, the possibilities of choice of the color-blind painter are determined by the nature of his color perception. Characteristic errors result from the fact that he has to choose between many hues which are different to a normal individual but which all look the same to him. 2) Evaluation of the clinical cases of painters with dyschromatopsias has shown evidence of the following: a) the color-blind painter makes mistakes according to the type of color defect; b) if the color-blind painter makes several copies of the same model, he makes different mistakes at each attempt; c) when several color-blind painters make copies of the same model, they also make different mistakes, even when they suffer from the same type of color vision defect. Preferences for some colored patterns were studied by means of a forced choice procedure and choices of color-blind individuals were often characteristic of their dyschromatopsia. Recent clinical case of acquired dyschromatopsia reported in the literature are discussed, as is a personal case of a painter suffering from tapeto-retinal degeneration. This was a severe dyschromatopsia with a neutral zone in purple (so-called scotpic axis, by Verriest's terminology). The painting of this artist tended to be monochromatic, mainly in green and green-blue colors. 3) Recent studies in art history have shown that only the romantic etcher Meryon was definitively color deficient. The more dubious cases of the Polish painter Grottger and of Eugène Carrière are discussed and conclusions are negative. Among acquired dyschromatopsias, there have been many recent papers devoted to cataract dyschromatopsias, concerning the cases of Rouault, Monet and Mary Cassatt. The hypothesis of a degree of chromatopsia or dyschromatopsia of toxic origin in the case of Van Gogh is also assessed. In conclusion, the problem of the relations between

Introduction: commentaries and author's response to "The rise and fall of the autochthonous self: from Italian Renaissance Art and Shakespeare to Hediegger, Lacan, and Intersubjectivism" by Richard D. Chessick.

PubMed

Leffert, Mark; Schwartz, Scott C; Chessick, Richard D

2011-01-01

This article addresses the unresolved question of the existence of a private core autochthonous self, as it has been described by Winnicott, Modell, and others. The postmodern version of the self has eliminated this concept entirely, relegating the self to a changing and unstable display, or regarding it as totally chaotic, or even an illusion. The question is raised whether by returning to the origins of this notion of a private self and then tracing its apparent dissolution it might be possible to discover some evidence that it still exists. The methodology used is that of obtaining knowledge directly through the arts and the claim is made that because empirical science has clamored to be the only source of knowledge, we have lost what could be obtained by direct intuitive seeing and experiencing the works of creative geniuses. To explore the rise of the autochthonous self this article provides an examination of the shift from Gothic art to Italian Renaissance art, a time which engendered the origin of "man" with his or her elusive private individual self that then became expressed in changing works of art. As this spread north, Shakespeare appeared and similarly invented and illustrated in his characters the private individual self, a concept not appreciated or recognized before the Renaissance. But as science arose and Western civilization began to decline, a corresponding disillusionment with "man" took place. The self began to be viewed as solely a social construction with no core except perhaps a genetic endowment. This was accompanied by a reduction in the concept of the human as a valuable and precious living being and was replaced by regarding the human as an object of control and exploitation. After the Second World War a movement in contemporary United States psychoanalysis gradually replaced the ideas of Freud and his emphasis on the "I" in the psychoanalytic process, with forms of relational therapy, assuming that the self was ab initio

Is Blast Injury a Modern Phenomenon?: Early Historical Descriptions of Mining and Volcanic Traumatic Brain Injury With Relevance to Modern Terrorist Attacks and Military Warfare.

Bowen, Lauren N; Moore, David F; Okun, Michael S

2016-03-01

Given the recent interest in blast injury spurred by returning soldiers from overseas conflicts, we sought to research the early historical descriptions of blast injuries and their treatments. Consideration was given to specific descriptions of survivors of closed head injury and their treatment. A review of the medical and nonmedical literature was undertaken, with particular emphasis on pre-1800 descriptions of volcanic eruptions and mining accidents. Compilations of accounts of the Etna eruptions dating from 126 BC were translated into English, and early mining texts from the 1600s and 1700s were reviewed. Accumulations of flammable gases were recorded in many medieval sources and this knowledge of toxic gas which could lead to blast injury was known in the mining community by 1316. No direct attribution of injuries to blast forces was present in the historical record examined before the 1300s, although mining accounts in the 1600s detail deaths due to blast. No specific descriptions of survivors of a closed head injury were found in the mining and volcanic eruption literature. Descriptions and warnings of blast forces were commonly written about in the medieval and Renaissance mining communities. Personal narratives as early as 1316 recognize the traumatic effects of blast injury. No mining or volcanic blast descriptions before 1800 detailed severe closed head injury survivors, suggesting greater mortality than morbidity from blast injury in the premodern era. This review also uncovered that there was no historical treatment or remedy recommended to survivors of blast injury. Blast explosions resulting in injury or death were frequently described, although in simplistic terminology.

The understanding of human biology and how it relates to that of other species represents an ancient quest. Limited access to human material, particularly during early development, has restricted researchers to only scratching the surface of this inherently challenging subject. Recent technological innovations, such as single cell "omics" and human stem cell derivation, have now greatly accelerated our ability to gain insights into uniquely human biology. The opportunities afforded to delve molecularly into scarce material and to model human embryogenesis and pathophysiological processes are leading to new insights of human development and are changing our understanding of disease and choice of therapy options.

The "thirsty dropsy": Early descriptions in medical and non-medical authors of thirst as symptom of chronic heart failure.

2017-10-15

Patients with chronic heart failure may suffer from severe thirst, even if mechanisms that cause thirst in subjects affected by this condition are not clear. Medical and non-medical authors may have already recognized this symptom during the classical age. We analyzed association between thirst and dropsy (an ancient medical term used to indicate different conditions including chronic heart failure) in past medical and non-medical literature. Hippocrates and Celsus first recognized thirst as a symptom of dropsy in the classical age. Greco-Roman intellectuals (Polybius, Ovid, Horace) and theologians belonging to the first years of the Christian era (Augustine, Caesarius, Gregory I) showed to know that dropsy people were often thirsty. These authors also influenced medieval poets and writers, including Dante Alighieri. In the Renaissance, the physician and alchemist Paracelsus again evidenced this symptom and the iatrochemist Robert Fludd tried to explain pathophysiology of dropsy, basing on thirst. The relationship between thirst and dropsy was well known by physicians and intellectuals in the classical age and in the first years of the Christian era, so influencing the Renaissance physicians.

Rhazes in the renaissance of Andreas Vesalius.

Compier, Abdul Haq

2012-01-01

Andreas Vesalius' (1514-64) first publication was a Paraphrasis of the ninth book of the Liber ad Almansorem, written by the Arab-Persian physician and alchemist Rhazes (854-925). The role of Rhazes in Vesalius' oeuvre has thus far been much disregarded. The different ways Rhazes recurs reveal an intellectual evolution in Vesalius' work. In the Paraphrasis, Vesalius subjects Rhazes to the authority of Galen in the context of the early sixteenth-century humanist campaign for the substitution of Arab influences by Greek 'originals'. Over the years Vesalius continues his work on Rhazes, but his approach becomes more internationalistic. Ultimately, Vesalius criticises Galen while expressing sympathy for the Arab author. This may be the more significant as Rhazes could have influenced Vesalius in the act of criticising Galen - critical discussions of Galen were available to Vesalius in Latin translations of Rhazes's Liber Continens. Although Vesalius never refers to the work, it is hardly possible he was unaware of it: similarities in structure, rhetoric and form between the Continens and the De humani corporis fabrica could support this hypothesis.

To study the role of individual and occupational risk factors for asthma in furniture workers. 296 workers were examined (258 men, 38 women) with a questionnaire of respiratory symptoms and diseases, baseline spirometry, bronchial provocative test with methacholine, and skin prick tests. Non-specific bronchial hyperreactivity was defined as when a provocative dose with a fall of 20% in forced expiratory volume in 1 second (PD20FEV1) was < 0.8 mg and atopy in the presence of at least one positive response to skin prick tests. Workers were subdivided into spray painters (exposed to low concentrations of diisocyanates and solvents), woodworkers (exposed to wood dusts), and assemblers (control group). The prevalences of attacks of shortness of breath with wheezing and dyspnoea were higher in spray painters (13.5% and 11.5% respectively) than in woodworkers (7.7% and 6.3%) or in assemblers (1.6% and 1.6%); prevalences of chronic cough, asthma, and rhinitis were also slightly but not significantly higher in spray painters and in woodworkers than in assemblers. The difference in the prevalence of respiratory symptoms among the job titles was due to the atopic subjects, who showed a higher prevalence of chronic cough, wheeze, shortness of breath with wheeze, dyspnoea, and asthma in spray painters than in the other groups. The prevalence of non-specific bronchial hyperreactivity in subjects who performed bronchial provocative tests was 17.7%, with no significant difference among groups. Asthma symptoms were significantly associated with non-specific bronchial hyperreactivity. Asthma-like symptoms plus non-specific bronchial hyperreactivity was found in 4% of assemblers, 10% of woodworkers, and 13.3% of spray painters (chi 2 = 2.6, NS).

To a glass scientist, the name “Fulcher” conjures images of viscosity vs. temperature diagrams for glass-forming liquids. Indeed, Gordon Fulcher’s seminal 1925 publication, in which he proposed his three-parameter model of viscosity, is one of the most significant and influential papers ever published in the field of glass science. Fulcher developed this equation during the early part of his 14-year career at Corning Glass Works (1920-1934). However, Fulcher’s work in viscosity represents a small fraction of his highly diverse and accomplished career, which included pioneering the field of electrocast ceramics and developing the modern system of scientific abstracting that it still in use today. Fulcher also had a keen interest in social and economic problems, and his latter research focused heavily on the field of metacognition, i.e., the process of thinking.

Fidelity analysis of mechanically aided copying/enlarging of Jan van Eyck's Portrait of Niccolo Albergati

NASA Astrophysics Data System (ADS)

Stork, David G.; Duarte, Marco

2007-01-01

The contemporary artist David Hockney has hypothesized that some early Renaissance painters secretly projected optical images onto their supports (canvas, paper, oak panel, ...), directly traced these projections, and then filled in the tracings with paint[1]. Hockney has presented somewhat impressionistic image evidence for this claim, but he and thin-film physicist Charles Falco also point to perspective anomalies, to the fidelity of passages in certain paintings, and to historical documents in search of support for this direct tracing claim[2]. Key visual evidence adduced in support of this tracing claim is a pair of portraits by Jan van Eyck of Cardinal Niccolo Albergati - a small informal silverpoint study of 1431 and a slightly larger formal work in oil on panel of 1432. The contours in these two works bear striking resemblance in shape (after being appropriately scaled) and there are at least two "relative shifts" - passages that co-align well after a spatial shift of one of the images [2]. This evidence has led the theory's proponents to claim that van Eyck copied the silverpoint by means of an optical projector, or epidiascope, the relative shifts due to him accidentally bumping the setup during the copying. Previous tests of the tracing theory for these works considered four candidate methods van Eyck might have used to copied and enlarged the image in the silverpoint study: unaided ("by eye"), mechanical, grid, and the optical projection method itself [3]. Based on the full evidence, including the recent discovery of tiny pinprick holes in the silverpoint, reenactments, material culture and optical knowledge in the early 15th century, the mechanical method was judged most plausible and optical method the least plausible[3]. However, this earlier work did not adequately test whether a trained artist could "re-enact" the copying by mechanical methods: "Although we have not explicitly verified that high fidelities can be achieved through the use of a

Biological Monitoring of Blood Naphthalene Levels as a Marker of Occupational Exposure to PAHs among Auto-Mechanics and Spray Painters in Rawalpindi

PubMed Central

2011-01-01

Background Routine exposure to chemical contaminants in workplace is a cause for concern over potential health risks to workers. In Pakistan, reports on occupational exposure and related health risks are almost non-existent, which reflects the scarce availability of survey data and criteria for determining whether an unsafe exposure has occurred. The current study was designed to evaluate blood naphthalene (NAPH) levels as an indicator of exposure to polycyclic aromatic hydrocarbons (PAHs) among automobile workshop mechanics (MCs) and car-spray painters (PNs). We further determined the relationship between blood NAPH levels and personal behavioural, job related parameters and various environmental factors that may further be associated with elevated risks of occupational exposures to PAHs. Methods Sixty blood samples (n = 20 for each group i.e. MC, PN and control group) were collected to compare their blood NAPH levels among exposed (MCs and PNs) and un-exposed (control) groups. Samples were analyzed using high pressure liquid chromatography (HPLC). Data regarding demographic aspects of the subjects and their socioeconomic features were collected using a questionnaire. Subjects were also asked to report environmental hygiene conditions of their occupational environment. Results We identified automobile work areas as potential sites for PAHs exposure, which was reflected by higher blood NAPH levels among MCs. Blood NAPH levels ranged from 53.7 to 1980.6 μgL-1 and 54.1 to 892.9 μgL-1 among MCs and PNs respectively. Comparison within each group showed that smoking enhanced exposure risks several fold and both active and passive smoking were among personal parameters that were significantly correlated with log-transformed blood NAPH levels. For exposed groups, work hours and work experience were job related parameters that showed strong associations with the increase in blood NAPH levels. Poor workplace hygiene and ventilation were recognized as most significant

[Anatomia practica: features from the history of early patho-anatomy].

PubMed

Jensen, Olaf Myhre

2002-01-01

Since the anatomy school of Alexandria during the fourth og third century before Christ dissection of the human body seems not to have been practiced until late Medieval or early Renaissance period, undoubtedly due to ethical and religious aversions. The teaching of anatomy was based on Galen using animal dissection. In the fourteenth and fifteenth centuries, however, anatomical examinations of the human body slowly began, seemingly for the purpose of describing both the normal structure and the abnormal structure caused by diseases, maldevelopment or trauma. This latter branch of anatomy was called practical, medical or correlative anatomy and corresponds to what we today name as patho-anatomy. Antonio Benivieni of Florence (1442-1502) is the first one to collect (and publish) a series of clinical observations some of which could be correlated to post mortem findings. It is unknown, however, whether the autopsies were performed by himself; and there is no mentioning of technique or circumstances for sectioning. Studies of the dead body by incision for the purpose of displaying diseased organs (autopsy) seem to have been an accepted practice for which relatives consented in those days. Other medical doctors in the years to follow, as for instance Fernel (1485-1558) in Paris, Eustachius (1524-1574) in Rome, Felix Plater (1536-1614) in Basle and Th. Bartholin (1616-1680) in Copenhagen have used the anatomical method for the study of diseases. Further, Schenck (1530-1598) in Freiburg and Bonet (1620-1689) in Genéva collected and published large series of clinical symptoms which had been related to post mortem findings dating back to ancient observers. This is the scientific background for anatomists as Morgagni, Lieutaud, Baillie, Bichât and others who founded the morbid anatomy on which the study of disease flourished in the classical patho-anatomical era of the nineteenth century with names as Rokitanski and Virchow.

Genotoxic damage in auto body shop workers.

Some studies have shown increased DNA damage among car painters, but other professionals working in auto body and paint shops have not been extensively assessed. The aim of this study was to assess DNA damage in different types of auto body shop workers by measuring micronucleus (MN) levels in exfoliated buccal cells. The mean number of cells with MN per 2000 exfoliated buccal cells was analyzed in three groups of male workers: auto body repair technicians, painters, and office workers (control group). All participants answered a questionnaire inquiring about age, smoking habits, alcohol consumption, work practices, occupational exposure time, job activities, and use of protective equipment. The mean number of cells with MN was 3.50 ± 1.50 in auto body painters, 3.91 ± 2.10 in auto body repair technicians, and 0.80 ± 0.78 in office workers, with a significant difference between the control group and the two other groups (p = 0.0001). Age, occupational exposure time, use of protective masks, alcohol consumption, and smoking habit did not affect MN results. The findings indicate that technicians and painters working in auto body shops are at risk for genotoxic damage, while office workers seem to be protected.

The study of Einstein's theory of general relativity experienced a renaissance beginning in the early 1960s. Prior to this resurgence of interest, general relativity was isolated from mainstream physics-admired for its elegance, perhaps, but only from a distance. The generation of students who risked their careers by entering this neglected field has now reached the age of festschrifts. In June of 2000, Caltech hosted ;Kipfest,; a conference in honor of Kip Thorne's 60th birthday. Thorne started graduate school at Princeton in 1962 and began research in general relativity under John Wheeler's guidance in the heady early days of the renaissance. Since then, he has played a prominent role in general relativity: as co-author of the influential textbook Gravitation, as a leader in research regarding astrophysical applications of Einstein's theory, and as a co-founder and chief advocate for the Laser Interferometer Gravitational Wave Observatory (LIGO), to mention a few aspects of his far-reaching work. ;Kipfest; included 14 speakers discussing fields to which Thorne has contributed. But the conference also reflected Thorne's long-standing commitment to communicating science to a general audience: Igor Novikov, Stephen Hawking, Timothy Ferris, and Alan Lightman gave popular talks at ;Kipfest,; with Thorne himself tricked into delivering a fifth. The Future of Spacetime gathers adaptations of these five lectures, along with a lengthy introductory essay by Richard Price.

In August 1945, a year after Rome was liberated from the Germans, I was on holiday with my family and a group of young physicists in Italy's Apennine Mountains. We were following a tradition that began in the 1920s whereby the physicists of Enrico Fermi's "Rome group" would always spend their vacations together. But the rest of the group - Franco Rasetti, Emilio Segrè, Bruno Pontecorvo and Fermi himself - had left Italy before the outbreak of the Second World War and of the group known as "i ragazzi di Via Panisperna" (the boys from Panisperna Street), as they were later dubbed by the senior members of the faculty, my father Edoardo Amaldi was the only one still there.

Hooke's figurations: a figural drawing attributed to Robert Hooke.

PubMed

Hunter, Matthew C

2010-09-20

The experimental philosopher Robert Hooke (1635-1703) is known to have apprenticed to the leading painter Peter Lely on his first arrival in London in the late 1640s. Yet the relevance of Hooke's artistic training to his mature draughtsmanship and identity has remained unclear. Shedding light on that larger interpretive problem, this article argues for the attribution to Hooke of a figural drawing now in Tate Britain (T10678). This attributed drawing is especially interesting because it depicts human subjects and bears Hooke's name functioning as an artistic signature, both highly unusual features for his draughtsmanship. From evidence of how this drawing was collected and physically placed alongside images by leading artists in the early eighteenth century, I suggest how it can offer new insight into the reception of Hooke and his graphic work in the early Enlightenment.

Aberration analysis of the putative projector for Lorenzo Lotto's Husband and wife: image analysis through computer ray-tracing

NASA Astrophysics Data System (ADS)

Robinson, Dirk; Stork, David G.

2008-02-01

A recent theory claims that the late-Italian Renaissance painter Lorenzo Lotto secretly built a concave-mirror projector to project an image of a carpet onto his canvas and trace it during the execution of Husband and wife (c. 1543). Key evidence adduced to support this claim includes "perspective anomalies" and changes in "magnification" that the theory's proponents ascribe to Lotto refocusing his projector to overcome its limitations in depth of field. We find, though, that there are important geometrical constraints upon such a putative optical projector not incorporated into the proponents' analyses, and that when properly included, the argument for the use of optics loses its force. We used Zemax optical design software to create a simple model of Lotto's studio and putative projector, and incorporated the optical properties proponents inferred from geometrical properties of the depicted carpet. Our central contribution derives from including the 116-cm-wide canvas screen; we found that this screen forces the incident light to strike the concave mirror at large angles (>= 15°) and that this, in turn, means that the projected image would reveal severe off-axis aberrations, particularly astigmatism. Such aberrations are roughly as severe as the defocus blur claimed to have led Lotto to refocus the projector. In short, we find that the projected images would not have gone in and out of focus in the way claimed by proponents, a result that undercuts their claim that Lotto used a projector for this painting. We speculate on the value of further uses of sophisticated ray-tracing analyses in the study of fine arts.

Cancer mortality among workers exposed to zinc chromate paints.

1980-01-01

To evaluate the carcinogenicity of chromium compounds among user industries, the proportionate mortality experience of spray painters exposed to zinc chromate primer paints and electroplaters exposed to chromic acid in the aircraft maintenance industry was examined. Compared to the mortality patterns of U.S. white males, no excess of cancer was found in the 48 deaths among electroplaters. Analysis of the 202 deaths among spray painters revealed a significant excess of cancer, primarily of the respiratory tract. The relative increase of respiratory cancer showed a positive gradient with the length of estimated exposure time, and was confined to painters whose interval from first employment to death was at least 20 years. The findings consistent with occupational exposure to chromium compounds, previously shown to be carcinogenic in manufacturing processes, but the effect of other paint constituents, tobacco smoking, or methodologic limitations could not be discounted.

Ambrosius Holbein's memento mori map for Sir Thomas More's Utopia. The meanings of a masterpiece of early sixteenth century graphic art.

PubMed

Bishop, M

2005-07-23

This paper describes how, and asks why, the Renaissance artist Ambrosius Holbein hid a skull within the overall design of his woodcut map of Sir Thomas More's Utopia. (Fig. 2) This map was prepared for the 1518 Froben edition of the book, and was probably commissioned by Erasmus of Rotterdam. Its identification now is made easier by the habits of interpretation with which all dentists are equipped thanks to their skill in dental radiology, and by the recognition of teeth appearing in an unlikely disguise.

Early concepts and charts of ocean circulation

NASA Astrophysics Data System (ADS)

Peterson, R. G.; Stramma, L.; Kortum, G.

little about them was reported in the Classical works. Following the dark and Middle Ages, when little progress was made, the voyages of discovery brought startling observations of many of Earth's most important ocean currents, such as the North and South Equatorial currents, the Gulf Stream, the Agulhas, Kuroshio, Peru, and Guinea currents, and others. The Gulf Stream appears to have been mapped as early as 1525 (Ribeiro) on the basis of Spanish pilot charts. Some currents were found to be westward, in the direction of the primum mobile as expected by theologians and philosophers, while others were not. The fifteenth through seventeenth centuries were marked by attainments of knowledge that increasingly taxed the abilities of science writers to reconcile new information with accepted doctrine. Consequences of this were descriptions of ocean circulation that questioned doctrine, yet were limited by it (Martyr; Gilbert; Bourne; Varen), while other descriptions disdainfully violated observation (Kircher; Happel). The expectation of a continuous westward oceanic flow around Earth in the direction of the primum mobile was so pervasive that it became central to arguments about a need for a passage through or around the Canadian north, and thus weighed significantly on the exploration and mapping of North America. Religious influences and the conceptual importance of the primum mobile waned by the close of the Renaissance and wind came to be seen as the primary cause of ocean currents (Dampier). The Gulf Stream (Franklin) and other North Atlantic flow patterns (de Brahm), as well as the southern Agulhas Current (Rennell), were mapped in the mid-to-late eighteenth century. Significant advances beyond these in determining the global ocean circulation came only after the routine determination of longitude at sea was instituted. The introduction of the marine chronometer in the late eighteenth century (Harrison) made this possible. By the end of the eighteenth century it was

The Church of San Miniato al Monte, Florence: Astronomical and Astrological Connections

NASA Astrophysics Data System (ADS)

Shrimplin, V.

2011-06-01

The church of San Miniato al Monte is examined in the context of interest in astrology and astronomy in early Renaissance Florence. Vitruvius emphasised the need for architects to "be acquainted with astronomy and the theory of the heavens" in his famous Ten Books of Architecture and, at San Miniato, astronomical and astrological features are combined in order to link humanity with the celestial or spiritual realm. The particular significance of Pisces and Taurus is explored in relation to Christian symbolism, raising questions about the role of astronomy and astrology in art and architecture.

"[N]ot subject to our sense” : Margaret Cavendish's fusion of Renaissance science, magic and fairy lore.

PubMed

Walters, Lisa

2010-01-01

This article explores Margaret Cavendish's depictions of alchemy, witchcraft and fairy lore in her scientific treatise Philosophical Letters and in fictional texts from Natures Pictures and Poems and Fancies. Though Cavendish was a dedicated materialist, she appropriates theories of magic from early modern science and folklore into her materialist epistemology. As Cavendish draws upon a fusion of early modern conceptions of magic, she creates a radical theory of matter which not only challenges patriarchy and binary oppositions, but also explores the plurality and mystery that can exist within an infinitely complex material world.

Disability Pensions due to Skin Diseases: A Cohort Study in Swedish Construction Workers.

PubMed

Meding, Birgitta; Wrangsjö, Karin; Burdorf, Alex; Järvholm, Bengt

2016-02-01

Disability pensions due to skin diseases in Swedish male construction workers were studied by linking data from pension registers and an occupational health service. Incidence rates of disability pensions for cement workers, painters and plumbers were compared with 2 control groups. A total of 623 disability pensions were granted during 4 decades of follow-up. The main diagnoses were eczema (36%) and psoriasis (49%). Pensions were mostly granted in the age range 55-64 years. Among painters, cement workers and plumbers the incidence rates for disability pensions were 33.3, 24.5 and 20.4 cases/100,000 person-years, respectively, compared with 13.7 and 9.2 cases/100,000 person-years in control groups. Relative risks were highest for eczema, and were notable for psoriasis. Attributable fractions for eczema were 90% in cement workers and painters and 75% in plumbers compared with control groups. Attributable fractions for psoriasis in the occupational groups studied were in the range 54-67%. In conclusion, eczema and psoriasis have a high impact on loss of work ability, as reflected by disability pensions.

We report the case of a 43-yr-old car painter who died within 1 h of exposure to a polyurethane paint in the workplace. A diagnosis of asthma induced by toluene diisocyanate (TDI) had been established 6 yr before, when he underwent inhalation challenges with carbachol and with TDI. The subject had airway hyperresponsiveness to carbachol (PD20FEV1 carbachol = 0.32 mg; normal value greater than 1.0 mg) and developed an early and long-lasting asthmatic reaction after exposure to TDI in the laboratory. Although it was recommended that he change his job or stop using paints containing isocyanates, he continued to workmore » as a car painter, taking antiasthmatic drugs both at work and at home to control asthma symptoms. On Monday, October 6, 1986, at 11:30 A. M., he developed a severe attack of asthma while he was mixing the 2 components of a polyurethane paint. Taken to hospital, he was dead on arrival. Autopsy showed no evidence of cardiac or brain disease; lungs were overinflated, the cut surface showed grey glistening mucous plugs in in the airways. Histologic examination showed denudation of airway epithelium and thickening of the basement membrane with infiltration of the lamina propria by polymorphonuclear leukocytes, mainly eosinophils, and diffuse mucous plugging of bronchioles. Bronchial smooth muscle appeared hyperplastic and disarrayed, and lung parenchyma showed focal areas of alveolar destruction adjacent to areas of perfectly intact alveolar walls.« less

The influence of retinal eye diseases on painting.

Ivanišević, Petar; Ivanišević, Milan

2015-03-01

In this work the possible influences of some retinal eye problems on paintings of several famous artists are considered. The change of painting styles and artistic expression in different periods and ages in a group of world-wide well-known painters are described and correlated with known or suspected retinal diseases. Some of them largely became recognizable because of that. Contemplations are offered about the effects of retinal diseases in the works of Degas, Munch, Cézanne, O'Keeffe, Constable and Goya. Retinal eye diseases have a significant impact on the work of selected famous painters.

The first cell-fate decisions in the mouse embryo: destiny is a matter of both chance and choice.

PubMed

Zernicka-Goetz, Magdalena

2006-08-01

Development of the early mouse embryo has always been classified as regulative, meaning that when parts or blastomeres of the embryo are isolated they change their developmental fate and can even reconstruct the whole. However, regulative development does not mean that, in situ, these parts or blastomeres are equivalent; it does not mean that the early mammalian embryo is a ball of identical cells without any bias. Regulative development simply means that whatever bias the regions of the embryo might have they still remain flexible and can respond to experimental interference by changes of fate. This realization -- that regulative development and patterning can co-exist -- has led to a renaissance of interest in the first days of development of the mouse embryo, and several laboratories have provided evidence for some early bias. Now the challenge is to gain some understanding of the molecular basis of this bias.

Pure curiosity has been the driving force behind many groundbreaking experiments in physics. This is no better illustrated than in quantum mechanics, initially the physics of the extremely small. Since its beginnings in the 1920s and 1930s, researchers have wanted to observe the counterintuitive properties of quantum mechanics directly in the laboratory. However, because experimental technology was not sufficiently developed at the time, people like Niels Bohr, Albert Einstein, Werner Heisenberg and Erwin Schrödinger relied instead on "gedankenexperiments" (thought experiments) to investigate the quantum physics of individual particles, mainly electrons and photons.

Cosmetics have been studied for a long time in the society and culture research, and its consumption is regarded as a cultural symbol of human society. This paper focuses on the analysis of the red cosmetic sticks, found in Xiaohe Cemetery (1980-1450BC), Xinjiang, China. The structure of the red cosmetic sticks was disclosed by SR-μCT scanning (Synchrotron Radiation Micro-computed Tomography), while the chemical components were characterized by FTIR (Fourier Transform Infrared Spectroscopy), Raman Spectroscopy and Proteomics. The results suggested that the cosmetic sticks were made from the cattle heart and covered with a layer of hematite powders as the pigment. Given the numerous red painted relics in Xiaohe Cemetery, this kind of cosmetic sticks might be used as a primitive form of crayon for makeup and painting. The usage of cattle hearts as cosmetic sticks is firstly reported up to our knowledge, which not only reveals the varied utilizations of cattle in Xiaohe Cemetery but also shows the distinctive religious function. Furthermore, these red cosmetic sticks were usually buried with women, implying that the woman may be the painter and play a special role in religious activities.

Estrogen-related receptor β (ERRβ) – renaissance receptor or receptor renaissance?

PubMed Central

Divekar, Shailaja D.; Tiek, Deanna M.; Fernandez, Aileen; Riggins, Rebecca B.

2016-01-01

Estrogen-related receptors (ERRs) are founding members of the orphan nuclear receptor (ONR) subgroup of the nuclear receptor superfamily. Twenty-seven years of study have yet to identify cognate ligands for the ERRs, though they have firmly placed ERRα and ERRγ at the intersection of cellular metabolism and oncogenesis. The pace of discovery for novel functions of ERRβ, however, has until recently been somewhat slower than that of its family members. ERRβ has also been largely ignored in summaries and perspectives of the ONR literature. Here, we provide an overview of established and emerging knowledge of ERRβ in mouse, man, and other species, highlighting unique aspects of ERRβ biology that set it apart from the other two estrogen-related receptors, with a focus on the impact of alternative splicing on the structure and function of this receptor.

Tradition and the individual sodomite: Barnfield, Shakespeare, and subjective desire.

PubMed

Bredbeck, G W

1992-01-01

This article compares Shakespeare's sonnets with those written by Richard Barnfield in order to examine the possibility of homoerotic subjectivity in early Renaissance England. Social constructionist debates about sexual subjectivity have convincingly argued that "the homosexual"--the person defined by homosexuality--did not exist before the Enlightenment. The sequences of Shakespeare and Barnfield, both of which deal with homoerotic desire, suggest that homoerotic desire could indeed play a role in defining the individuated subject prior to the Enlightenment. However, the ways in which they use homoeroticism also suggest that subjectivity was defined in radically different ways during the period.

Today's neuroanatomical terminology has its origins in the Romans' way of life, in their civil and military house architecture, as well as in the fields of engineering and technology. Despite the fact that they did not know how the nervous system worked and what the role of each neuroanatomic structure was, over time, especially in Renaissance and early modern times, the anatomists sought descriptive names for the nervous structures they have identified by way of similarity with some ancient items. This study aims to briefly review the influence of Roman architecture, engineering, and technology on neuroanatomic nomenclature, the precursor of modern neuroanatomical terminology.

A figure resembling Michelangelo at the age of 36 appears to have nodules resembling tophi over his knees.In this report, we review Michelangelo's medical history, discuss the proposal that he had tophaceous gout, and address the significance of "knobby" knees in his works and those of other artists.

Soap bubbles in paintings: Art and science

NASA Astrophysics Data System (ADS)

Behroozi, F.

2008-12-01

Soap bubbles became popular in 17th century paintings and prints primarily as a metaphor for the impermanence and fragility of life. The Dancing Couple (1663) by the Dutch painter Jan Steen is a good example which, among many other symbols, shows a young boy blowing soap bubbles. In the 18th century the French painter Jean-Simeon Chardin used soap bubbles not only as metaphor but also to express a sense of play and wonder. In his most famous painting, Soap Bubbles (1733/1734) a translucent and quavering soap bubble takes center stage. Chardin's contemporary Charles Van Loo painted his Soap Bubbles (1764) after seeing Chardin's work. In both paintings the soap bubbles have a hint of color and show two bright reflection spots. We discuss the physics involved and explain how keenly the painters have observed the interaction of light and soap bubbles. We show that the two reflection spots on the soap bubbles are images of the light source, one real and one virtual, formed by the curved surface of the bubble. The faint colors are due to thin film interference effects.

Allergic contact hobby dermatitis from turpentine.

2008-01-01

Turpentine is an oleoresin obtained from various species of pine. It contains a volatile oil (oil of turpentine) which is responsible for its properties and this is the form generally used. Opportunity for contact with turpentine is widespread. It is universally used as a solvent to dissolve and thin lacquers, varnishes and paints. It is also an ingredient in many liniments and cold remedies. Turpentine is regarded as both a local irritant and a sensitizer. Cases of allergic contact dermatitis in painters, mechanics, shoe repairers and home decorators have been reported. We report a case of a non-professional painter who developed a contact allergic dermatitis due to his exposure to turpentine while doing oil-painting as a hobby. Dermatitis is one of the biggest dangers of working with art materials and occupational contact dermatitis is often detected on the hands of the painters. Solvents are indispensable and turpentine is the most important and the traditional one used in oil-painting. Contact allergy to oil of turpentine was reported to have become rare in Europe but over the last few years, increased rates of turpentine sensitization have been reported.

Chapter 17: Occupational immunologic lung disease.

PubMed

Sabin, Bradley R; Grammer, Leslie C

2012-01-01

Occupational immunologic lung disease is characterized by an immunologic response in the lung to an airborne agent inhaled in the work environment and can be subdivided into immunologically mediated occupational asthma (OA) and hypersensitivity pneumonitis (HP). Irritant-induced OA, a separate nonimmunologic entity, can be caused by chronic exposure to inhaled irritants or reactive airways dysfunction syndrome, defined as an asthma-like syndrome that persists for >3 months and occurs abruptly after a single exposure to a high concentration of an irritating industrial agent. High-risk fields for OA include farmers, printers, woodworkers, painters, plastic workers, cleaners, spray painters, electrical workers, and health care workers. OA can be triggered by high molecular weight (HMW) proteins that act as complete allergens or low molecular weight (LMW) sensitizers that act as haptens. HMW proteins (>10 kDa) are generally derived from microorganisms (such as molds and bacteria, including thermophilic actinomycetes), plants (such as latex antigens and flour proteins), or animals (such as animal dander, avian proteins, and insect scales) and are not specifically regulated by the Occupational Safety and Health Administration (OSHA). LMW haptens that bind to proteins in the respiratory mucosa include some OSHA-regulated substances such as isocyanates, anhydrides, and platinum. HP can present in an acute, a chronic, or a subacute form. The acute, subacute, and early chronic form is characterized by a CD4(+) T(H)1 and CD8(+) lymphocyte alveolitis. Classically, the bronchoalveolar lavage will show a CD4/CD8 ratio of <1.

Combined use of FORS, XRF and Raman spectroscopy in the study of mural paintings in the Aosta Valley (Italy).

2009-12-01

Mural paintings which decorate the external façade and the internal apsidal wall of a chapel dedicated to St. Maxime and located at Challand St. Victor in the Aosta Valley (Italy) have been analysed with a combined approach involving high-resolution fibre-optic reflectance spectroscopy (FORS), X-ray fluorescence (XRF) spectrometry and Raman spectroscopy. The paintings are attributed to Giacomino from Ivrea, a painter active around the mid-fifteenth century. In order to characterise the palette used by the painter and to yield information useful to restorers, the cited techniques were used either in situ with portable instruments and in laboratory, working on micro samples withdrawn from paintings. The global analytical approach, though not entirely non-invasive, can indeed be considered non-destructive as multiple analyses, including SEM-EDX, could be carried out on the micro samples, exploiting the features of each technique. On the basis of the information obtained, the palette was found to be composed of typical fresco pigments such as calcite, azurite, malachite, vermilion, red and yellow ochres. A particular situation was noted for black pigments since the presence of graphite, rather than wood or lamp carbon, was found, possibly related to the presence of graphite deposits in the Aosta Valley. Furthermore, the presence of smalt superimposed to azurite in areas showing evidence of repainting was detected, suggesting that paintings were subjected to retouching at a relatively early stage after the original execution. Finally, the presence of tin foils, used to decorate haloes of Evangelists, was ascertained.

A great enigma of the Italian Renaissance: paleopathological study on the death of Giovanni dalle Bande Nere (1498-1526) and historical relevance of a leg amputation.

The Medici project consisted in archeological and paleopathological researches on some members of the great dynasty of the Italian Renaissance. The remains of Giovanni de' Medici, so-called "dalle Bande Nere" (Forlì 1498- Mantua 1526) have not been investigated yet. The enigma of the fatal injury and leg amputation of the famous Captain excited curiosity of paleopathologists, medical scientists and Italian Society of Orthopedic and Traumatology which contributed to realize the project of exhumation and study of his skeletal remains. The aim of the study is to report the first anthropological and paleopathological results. The tomb of Giovanni and his wife Maria Salviati was explored and the skeletal remains were investigated. Anthropological and paleopathological examination defined: age at death, physical constitution and activity, skeletal diseases. The bones of the leg were studied macroscopically, under stereoscopic microscope, at X-ray and CT scans to detect type of injury and level of amputation. The skeleton and muscular insertions of Giovanni revealed a young-adult and vigorous man, subjected to stresses of military activity since adolescence. Right tibia was amputated below the proximal half of diaphysis leaving long tibio-fibular stumps with a horizontal cut only at the lateral portion. Thus, the surgeon limited to complete the traumatic hemi-amputation. Amputation in the Sixteenth Century technically consisted in guillotine incisions below the knee using crescent shaped knife and bony saw, usually leaving a quite long tibial stump. Amputations in the Sixteenth Century were contaminated and grossly performed not providing vascular binding nor wound closure. The surgeon performed the procedure in conformity with surgical knowledge of that period.

The COPERNICUS trial lends further support to the use of the beta-blocker, carvedilol, in severe heart failure and the CAPRICORN trial to its use in patients with post-infarction left ventricular systolic dysfunction. The MIRACLE study reinforces the evidence from three smaller trials that cardiac resynchronisation therapy is an effective treatment for the relief of symptoms in patients with severe heart failure and cardiac dyssynchrony. The STAF trial casts further doubt on the wisdom of cardioversion as a routine strategy for the management of chronic atrial fibrillation. The RITZ-2 trial suggests that an intravenous, non-selective endothelin antagonist is effective in improving haemodynamics and symptoms and possibly in reducing morbidity in severe heart failure. Observational studies in heart failure suggest that a moderate excess of body fat and elevated blood cholesterol may be desirable in patients with heart failure, challenging the current non-evidenced-based vogue for cholesterol lowering therapy in heart failure. The RENAISSANCE and RECOVER outcome studies of etanercept, a tumour necrosis factor (TNF) receptor analogue that blocks the effect of TNF, were stopped because of lack of evidence of benefit shortly after the ACC.

The New Negro and the Ideological Origins of the Integrationist Movement.

Butler, Johnnella; Marable, Manning

The literature of the Negro Renaissance needs to be re-examined from the purview of the pervasiveness of the conflicts apparent in such literary themes as the tragic mulatto, the glorified and idealistic African past, the alienation from American culture, and an implied, and at times overt, self-hatred. The Renaissance literature reflects the…

Early Diagnosis and Early Intervention in Cerebral Palsy

PubMed Central

Hadders-Algra, Mijna

2014-01-01

This paper reviews the opportunities and challenges for early diagnosis and early intervention in cerebral palsy (CP). CP describes a group of disorders of the development of movement and posture, causing activity limitation that is attributed to disturbances that occurred in the fetal or infant brain. Therefore, the paper starts with a summary of relevant information from developmental neuroscience. Most lesions underlying CP occur in the second half of gestation, when developmental activity in the brain reaches its summit. Variations in timing of the damage not only result in different lesions but also in different neuroplastic reactions and different associated neuropathologies. This turns CP into a heterogeneous entity. This may mean that the best early diagnostics and the best intervention methods may differ for various subgroups of children with CP. Next, the paper addresses possibilities for early diagnosis. It discusses the predictive value of neuromotor and neurological exams, neuroimaging techniques, and neurophysiological assessments. Prediction is best when complementary techniques are used in longitudinal series. Possibilities for early prediction of CP differ for infants admitted to neonatal intensive care and other infants. In the former group, best prediction is achieved with the combination of neuroimaging and the assessment of general movements, in the latter group, best prediction is based on carefully documented milestones and neurological assessment. The last part reviews early intervention in infants developing CP. Most knowledge on early intervention is based on studies in high-risk infants without CP. In these infants, early intervention programs promote cognitive development until preschool age; motor development profits less. The few studies on early intervention in infants developing CP suggest that programs that stimulate all aspects of infant development by means of family coaching are most promising. More research is urgently needed

[Marcel Sembat's Psychology: the Hobby of a Politician?

PubMed

Carroy, Jacqueline

The socialist politician Marcel Sembat’s unpublished manuscripts reveal the unexpected figure of a diarist with a passion for his own intimate, bodily, sexual and affective economy, and of an autodidact and sometimes polemical reader of psychology (for instance Pierre Janet’s). Sembat was recognized nonetheless as a potentially publishable author by Georges Dumas, the editor of the Journal de psychologie normale et pathologique, who asked him to contribute an article – which was never published – on dreaming. Sembat was also particularly receptive to Freud’s early conceptions of sexuality. Was Marcel Sembat an amateur, like the painter Ingres playing the violin? Could he be characterized as a “psychologist from below”? As a dilettante? Or simply as a cultivated man according to the meaning this period ascribed to the term?

One health-one medicine: unifying human and animal medicine within an evolutionary paradigm.

PubMed

Currier, Russell W; Steele, James H

2011-08-01

One health is a concept since early civilization, which promoted the view that there was no major distinction between animal and human medicine. Although persisting through the 19th century, this common vision was then all but forgotten in the early 20th century. It is now experiencing a renaissance, coincident with an awakening of the role that evolutionary biology plays in human and animal health, including sexually transmitted infections (STIs). A number of STIs in humans have comparable infections in animals; likewise, both humans and animals have STIs unique to each mammalian camp. These similarities and differences offer opportunities for basic medical and public health studies, including evolutionary insights that can be gleaned from ongoing interdisciplinary investigation--especially with the molecular analytical tools available--in what can become a golden age of mutually helpful discovery. © 2011 New York Academy of Sciences.

A quantitative approach to painting styles

NASA Astrophysics Data System (ADS)

Vieira, Vilson; Fabbri, Renato; Sbrissa, David; da Fontoura Costa, Luciano; Travieso, Gonzalo

2015-01-01

This research extends a method previously applied to music and philosophy (Vilson Vieira et al., 2012), representing the evolution of art as a time-series where relations like dialectics are measured quantitatively. For that, a corpus of paintings of 12 well-known artists from baroque and modern art is analyzed. A set of 99 features is extracted and the features which most contributed to the classification of painters are selected. The projection space obtained provides the basis to the analysis of measurements. These quantitative measures underlie revealing observations about the evolution of painting styles, specially when compared with other humanity fields already analyzed: while music evolved along a master-apprentice tradition (high dialectics) and philosophy by opposition, painting presents another pattern: constant increasing skewness, low opposition between members of the same movement and opposition peaks in the transition between movements. Differences between baroque and modern movements are also observed in the projected "painting space": while baroque paintings are presented as an overlapped cluster, the modern paintings present minor overlapping and are disposed more widely in the projection than the baroque counterparts. This finding suggests that baroque painters shared aesthetics while modern painters tend to "break rules" and develop their own style.

Non-destructive methods are of great interest for the analysis of cultural heritage. Among the different possible techniques, this paper presents a low cost prototype based on the emission and reception of airborne ultrasound without direct contact with the test specimen. We successfully performed a method test for the detection of brick joints under a XV th century Renaissance fresco of the Metropolitan Cathedral of the city of Valencia (Spain). Both laboratory and in situ results are in agreement. Using this prototype system, an early moisture detection system has been installed in the dome that supports the fresco. The result is encouraging and opens interesting prospects for future research.

SANFORD,THOMAS W. L.

2000-05-23

Characteristics of annular wire-array z-pinches as a function of wire number and at high wire number are reviewed. The data, taken primarily using aluminum wires on Saturn are comprehensive. The experiments have provided important insights into the features of wire-array dynamics critical for high x-ray power generation, and have initiated a renaissance in z-pinches when high numbers of wires are used. In this regime, for example, radiation environments characteristic of those encountered during the early pulses required for indirect-drive ICF ignition on the NIF have been produced in hohlraums driven by x-rays from a z-pinch, and are commented on here.

THE ORIGIN OF THE CONCEPT OF NEUROPATHIC PAIN IN EARLY MEDIEVAL PERSIA (9TH-12TH CENTURY CE).

Heydari, Mojtaba; Shams, Mesbah; Hashempur, Mohammad Hashem; Zargaran, Arman; Dalfardi, Behnam; Borhani-Haghighi, Afshin

2015-01-01

Neuropathic pain is supposed to be a post-renaissance described medical entity. Although it is often believed that John Fothergill (1712-1780) provided the first description of this condition in 1773, a review of the medieval Persian medical writings will show the fact that neuropathic pain was a medieval-originated concept. "Auojae Asab" [Nerve-originated Pain] was used as a medical term in medieval Persian medical literature for pain syndromes which etiologically originated from nerves. Physicians like Rhazes (d. 925 CE), Haly Abbas (d. 982 CE), Avicenna (d. 1037 CE), and Jorjani (d. 1137 CE) have discussed multiple aspects of nerve-originated pain including its classification, etiology, differentiating characteristics, different qualities, and pharmacologic and non-pharmacologic treatments. Recognizing medieval scholars' views on nerve-originated pain can lighten old historical origins of this concept.

Use of brachytherapy with radioactive seeds in the management of early prostate cancer is commonly used in the United States. The early experience has been reported from the prostate treatment centers in Seattle for the last 10 years. In this manuscript we are reporting our early experience of 150 radioactive seed implantations in early stage prostate cancer using either Iodine 125 or Palladium 103 seeds. The average age of the patient is 66 years and the median Gleason score is 5.4 with a median PSA of 6. A brief description of the evolution of the treatment of prostate cancer as well as the preparation for the seed implantation using the volume study with ultrasound of the prostate, pubic arch study using CT scan of the pelvis and the complete planning using the treatment planning computers are discussed. We also have described the current technique which is used in our experience based on the Seattle guidelines. We plan a follow-up report with the results of the studies with longer follow-up.

2011-12-01

The purpose of this study was to examine whether early literacy skills uniquely predict early numeracy skills development. During the first year of the study, 69 3- to 5-year-old preschoolers were assessed on the Preschool Early Numeracy Skills (PENS) test and the Test of Preschool Early Literacy Skills (TOPEL). Participants were assessed again a year later on the PENS test and on the Applied Problems and Calculation subtests of the Woodcock-Johnson III Tests of Achievement. Three mixed effect regressions were conducted using Time 2 PENS, Applied Problems, and Calculation as the dependent variables. Print Knowledge and Vocabulary accounted for unique variance in the prediction of Time 2 numeracy scores. Phonological Awareness did not uniquely predict any of the mathematics domains. The findings of this study identify an important link between early literacy and early numeracy development. Copyright © 2011 Elsevier Inc. All rights reserved.

A Cosmologist's Tour Through the New Particle Zoo / Candy Shop

NASA Astrophysics Data System (ADS)

Turner, M. S.

Recent developments in elementary particle physics have led to a renaissance in cosmology, in general, and in the study of structure formation, in particular. Already, the study of the very early (t ≤ 10-2s) history of the Universe has provided valuable hints as to the 'initial data' for the structure formation problem - the nature and origin of the primeval density inhomogeneities, the quantity and composition of matter in the Universe today, and numerous candidates for the constituents of the ubiquitous dark matter. The author reviews the multitude of WIMP candidates for the dark matter provided by modern particle physics theories, putting them into context by briefly discussing the theories which predict them. He reviews their various birth sites and birth processes in the early Universe. The author also mentions some very exotic possibilities - unstable WIMPs, cosmic strings, and even the possibility of a relic cosmological term.

β-Lactam Antibiotics Renaissance

2014-01-01

Since the 1940s β-lactam antibiotics have been used to treat bacterial infections. However, emergence and dissemination of β-lactam resistance has reached the point where many marketed β-lactams no longer are clinically effective. The increasing prevalence of multidrug-resistant bacteria and the progressive withdrawal of pharmaceutical companies from antibiotic research have evoked a strong reaction from health authorities, who have implemented initiatives to encourage the discovery of new antibacterials. Despite this gloomy scenario, several novel β-lactam antibiotics and β-lactamase inhibitors have recently progressed into clinical trials, and many more such compounds are being investigated. Here we seek to provide highlights of recent developments relating to the discovery of novel β-lactam antibiotics and β-lactamase inhibitors. PMID:27025744

Cases of aphasia in a work on medicine from the 16th century.

PubMed

Munoz-Sanz, Augustin; Garcia-Avila, Juan Fernando; Vallejo, Jose Ramon

2014-01-01

The purpose of this paper is to bring to the attention of the international community the role in the history of aphasiology of the eminent Renaissance figure, the Extremaduran Francisco Arceo de Fregenal. To present the subject, after a brief biography of this surgeon, we will trace the development of the concept of aphasia up to the 16th century. In some ancient cultures we find that this disorder was described as a "cerebral accident", to be presented subsequently in the Middle Ages as a divine punishment, only for the original idea to be taken up again during the Renaissance. This return to the concept of the early civilisations was not to lead to the formal classification of this condition however, until the studies of Broca and Wernicke were published in the 19th century. The contribution of Arceo lies in the description of clinical cases included in his book De Recta cvrandorum, which are presented in their original written version in Latin accompanied by a translation in English. The first of these cases tells of spontaneous recovery from the disease, and the second of the evolution of a patient with aphasia secondary to traumatic brain injury following surgery. Despite the great value of Arceo's report, the historical context and his professional attitude did not allow for a localisationist interpretation of the concept of aphasia.

Two imaging modalities based on molecular and elemental spectroscopy were used to characterize a painting by Cosimo Tura. Visible-to-near-infrared (400-1680 nm) reflectance imaging spectroscopy (RIS) and X-ray fluorescence (XRF) imaging spectroscopy were employed to identify pigments and determine their spatial distribution with higher confidence than from either technique alone. For example, Mary's red robe was modeled through the distribution of an insect-derived red lake (RIS map) and lead white (XRF lead map), rather than a layer of red lake on vermilion. The RIS image cube was also used to isolate the preparatory design by mapping the reflectance spectra associated with it. In conjunction with results from an earlier RIS study (1650-2500 nm) to map and identify the binding media, a more thorough understanding was gained of the materials and techniques used in the painting. © 2014 WILEY-VCH Verlag GmbH & Co.

[On the ancient and magical lesions in the sixteenth to eighteenth centuries].

Hach, W; Hach-Wunderle, V

2014-11-01

At the beginning of the Renaissance magical, witchcraft and demonological medicine still played a large role in the poor healing ability of chronic leg ulcers. This included the general administration of magical potions and topical application. An example of the manipulation of the whole body by the devil was the Abracadabra text from Johann Christoph Bitterkraut in the year 1677. The use of bewitched ointments was particularly propagated by Paracelsus in 1622; however, even as early as the beginning of the seventeenth century, the invocation of supernatural powers was slowly diminishing until at the beginning of the nineteenth century the medical schools on chronic leg ulcers could be cultivated at the universities and by specialized wound healers.

Among the first three manuscripts written in Persian, Akhawayni’s Hidayat al-muta’allemin fi al-tibb was the most significant work compiled in the 10th century. Along with the hundreds of chapters on hygiene, anatomy, physiology, symptoms and treatments of the diseases of various organs, there is a chapter on sleep paralysis (night-mare) prior to description and treatment of epilepsy. The present article is a review of the Akhawayni’s teachings on sleep paralysis and of descriptions and treatments of sleep paralysis by the Greek, medieval, and Renaissance scholars. Akhawayni’s descriptions along with other early writings provide insight into sleep paralysis during the Middle Ages in general and in Persia in particular. PMID:22701323

Pre-colonial culture, post-colonial economic success? The Tswana and the African economic miracle.

PubMed

Hjort, Jonas

2010-01-01

Cultural explanations of economic phenomena have recently enjoyed a renaissance among economists. This article provides further evidence for the salience of culture through an in-depth case study of one of the fastest-growing economies in the world during the last 50 years-Botswana. The unique culture that developed among the Tswana before and during the early days of colonialism, which shared many features with those of western nation-states, appears to have contributed significantly to the factors widely seen as determinants of Botswana's post-colonial economic success: state legitimacy, good governance and democracy, commercial traditions, well-established property rights, and inter-ethnic unity. Neighbouring Southern African cultures typically did not exhibit these traits.

Are parity and the timing of menarche associated with premature and early natural menopause? Early menarche (≤11 years) is a risk factor for both premature menopause (final menstrual period, FMP <40 years) and early menopause (FMP 40-44 years), a risk that is amplified for nulliparous women. Women with either premature or early menopause face an increased risk of chronic conditions in later life and of early death. Findings from some studies suggest that early menarche and nulliparity are associated with early menopause, however overall the evidence is mixed. Much of the evidence for a direct relationship is hampered by a lack of comparability across studies, failure to adjust for confounding factors and inadequate statistical power. This pooled study comprises 51 450 postmenopausal women from nine observational studies in the UK, Scandinavia, Australia and Japan that contribute to the International collaboration for a Life course Approach to reproductive health and Chronic disease Events (InterLACE). Age at menarche (categorized as ≤11, 12, 13, 14 and 15 or more years) and parity (categorized as no children, one child and two or more children) were exposures of interest. Age at FMP was confirmed by at least 12 months of cessation of menses where this was not the result of an intervention (such as surgical menopause due to bilateral oophorectomy or hysterectomy) and categorized as premature menopause (FMP before age 40), early menopause (FMP 40-44 years), 45-49 years, 50-51 years, 52-53 years and 54 or more years. We used multivariate multinomial logistic regression models to estimate relative risk ratio (RRR) and 95% CI for associations between menarche, parity and age at FMP adjusting for within-study correlation. The median age at FMP was 50 years (interquartile range 48-53 years), with 2% of the women experiencing premature menopause and 7.6% early menopause. Women with early menarche (≤11 years, compared with 12-13 years) were at higher risk of premature

History and future of mask making

NASA Astrophysics Data System (ADS)

Levy, Ken L.

1996-12-01

The history of the mask industry has three main periods, which I call the Classical Period, the Dark Ages, and the Renaissance, by analogy with those periods in the history of Western Europe. During the Classical Period, people developed 1X masks and the technology to make them. In the Dark Ages, people exploited the equipment developed during the Classical Period to make 5X reduction reticle, ending the nobility of mask making. In today's Renaissance of mask making, a proliferation of mask types is requiring a rebirth of innovation and creativity. The Renaissance resembles the Classical Period: masks are once again strategic, and technological capability is once again the driver. Meanwhile, the mask industry is carrying forward the productivity and efficiency gains it achieved during the Dark Ages. We must create a new business and economic model to support these changes in the characteristics of the marketplace.

In the following contribution the relevant aspects of the broadsheet of the municipial physician from Nuremberg Theodoricus Ulsenius of 1496 are represented. The broadsheet attracted the attention of the history of art because of the wood-cut, attributed to Durer, and became famous as the so-called Picture of the Plague-Stricken Man. The history of medicine on the other hand identifies the unknown new disease, described by Ulsenius in the latin text, as an early description of syphillis. To men at the turn of the 16th century, this disease appeared as an expression of divine wrath. The Renaissance medical science, influenced by the philosophy of Neo-Platonism, explained its orgin as the consequence of a cosmological constellation. Apart from this the broadsheet as an incunabulum has some relevance for the history of early letter-press printing, of which Nuremberg with its circles of artists and scholars represented an important centre.

It is difficult to develop the financing and hospital provision of interventions for early rehabilitation within the diagnosis-related group (DRG) system. In addition to a range of partially rehabilitative complex interventions, the system recognizes three main forms of early rehabilitative interventions: geriatric, neurological/neurosurgical, and interdisciplinary and others. In this article, the appropriate definitions and cost-effectiveness of these procedures are analyzed and compared. The early rehabilitative interventions are characterized by constant cooperation in the therapeutic team, especially neurological early rehabilitation through the incorporation of nursing as a therapeutic profession. Whereas geriatric and neurological early rehabilitation are reflected in the DRG system, the former provided in many general hospitals and the latter mainly in specialized institutions, interdisciplinary early rehabilitation has only occasionally been represented in the DRG system so far. If all acute in-patients who require early rehabilitation should receive such an intervention, an additional fee must be implemented for this this interdisciplinary service.

On the telescopes in the paintings of Jan Brueghel the Elder

Molaro, Paolo; Selvelli, Pierluigi

2011-06-01

Several astronomical instruments including early spyglasses are depicted in at least five paintings that Jan Brueghel the Elder completed between 1608 and 1625. This rather unique circumstance is due to the fact that Jan Brueghel was court painter of Archduke Albert VII of Habsburg, whose love for art and science, he celebrated in his paintings. An optical tube that appears in the Extensive Landscape with View of the Castle of Mariemont, dated 1608-1612 represents the first painting of a telescope whatsoever. Some documents are collected showing that Albert VII could have obtained very early spyglasses directly from Lipperhey or Sacharias Janssen, who are two possible inventors of the telescope. Thus the painting could reproduce one of the first telescopes ever made by mankind. Two more instruments appear prominently in two Allegories of Sight made in the years 1617 and 1618. These are precious instruments made possibly in silver, composed by several draw-tubes, which look much more sophisticated than other instruments of same epoch. Rather surprisingly, the structure and, in particular the eyepiece, suggest that they may represent the first examples of Keplerian telescopes about two decades before they replaced the Dutch mounting.

Racial disparities persist in early childhood wheezing and cannot be completely explained by known risk factors. To evaluate the associations of genetic ancestry and self-identified race with early childhood recurrent wheezing, accounting for socio-economic status (SES) and early life exposures. We studied 1034 children in an urban, multi-racial, prospective birth cohort. Multivariate logistic regression was used to evaluate the association of genetic ancestry as opposed to self-identified race with recurrent wheezing (>3 episodes). Sequential models accounted for demographic, socio-economic factors and early life risk factors. Genetic ancestry, estimated using 150 ancestry informative markers, was expressed in deciles. Approximately 6.1% of subjects (mean age 3.1 years) experienced recurrent wheezing. After accounting for SES and demographic factors, African ancestry (OR: 1.16, 95% CI: 1.02-1.31) was significantly associated with recurrent wheezing. By self-reported race, hispanic subjects had a borderline decrease in risk of wheeze compared with African Americans (OR: 0.44, 95% CI: 0.19-1.00), whereas white subjects (OR: 0.46, 95% CI: 0.14-1.57) did not have. After further adjustment for known confounders and early life exposures, both African (OR: 1.19, 95% CI: 1.05-1.34) and European ancestry (OR: 0.84, 95% CI: 0.74-0.94) retained a significant association with recurrent wheezing, as compared with self-identified race (OR(whites) : 0.31, 95% CI: 0.09-1.14; OR(hispanic) : 0.47, 95% CI: 0.20-1.08). There were no significant interactions between ancestry and early life factors on recurrent wheezing. In contrast to self-identified race, African ancestry remained a significant, independent predictor of early childhood wheezing after accounting for early life and other known risk factors associated with lung function changes and asthma. Genetic ancestry may be a powerful way to evaluate wheezing disparities and a proxy for differentially distributed genetic and

Individual differences in early adolescents' latent trait cortisol (LTC): Relation to early adversity.

Stroud, Catherine B; Chen, Frances R; Doane, Leah D; Granger, Douglas A

2016-09-01

Substantial evidence suggests that youth who experience early adversity exhibit alterations in hypothalamic pituitary adrenal (HPA) axis functioning, thereby increasing risk for negative health outcomes. However, few studies have explored whether early adversity alters enduring trait indicators of HPA axis activity. Using objective contextual stress interviews with adolescents and their mothers to assess early adversity, we examined the cumulative impact of nine types of early adversity on early adolescents girls' latent trait cortisol (LTC). Adolescents (n = 122; M age = 12.39 years) provided salivary cortisol samples three times a day (waking, 30 min post-waking, and bedtime) over 3 days. Latent state-trait modeling indicated that the waking and 30 min post-waking samples contributed to a LTC factor. Moreover, greater early adversity was associated with a lower LTC level. Implications of LTC for future research examining the impact of early adversity on HPA axis functioning are discussed. © 2016 Wiley Periodicals, Inc.

Earth's early biosphere

NASA Technical Reports Server (NTRS)

Des Marais, D. J.

1998-01-01

Understanding our own early biosphere is essential to our search for life elsewhere, because life arose on Earth very early and rocky planets shared similar early histories. The biosphere arose before 3.8 Ga ago, was exclusively unicellular and was dominated by hyperthermophiles that utilized chemical sources of energy and employed a range of metabolic pathways for CO2 assimilation. Photosynthesis also arose very early. Oxygenic photosynthesis arose later but still prior to 2.7 Ga. The transition toward the modern global environment was paced by a decline in volcanic and hydrothermal activity. These developments allowed atmospheric O2 levels to increase. The O2 increase created new niches for aerobic life, most notably the more advanced Eukarya that eventually spawned the megascopic fauna and flora of our modern biosphere.

Abnormal early cleavage events predict early embryo demise: sperm oxidative stress and early abnormal cleavage.

PubMed

Burruel, Victoria; Klooster, Katie; Barker, Christopher M; Pera, Renee Reijo; Meyers, Stuart

2014-10-13

Human embryos resulting from abnormal early cleavage can result in aneuploidy and failure to develop normally to the blastocyst stage. The nature of paternal influence on early embryo development has not been directly demonstrated although many studies have suggested effects from spermatozoal chromatin packaging, DNA damage, centriolar and mitotic spindle integrity, and plasma membrane integrity. The goal of this study was to determine whether early developmental events were affected by oxidative damage to the fertilizing sperm. Survival analysis was used to compare patterns of blastocyst formation based on P2 duration. Kaplan-Meier survival curves demonstrate that relatively few embryos with short (<1 hr) P2 times reached blastocysts, and the two curves diverged beginning on day 4, with nearly all of the embryos with longer P2 times reaching blastocysts by day 6 (p < .01). We determined that duration of the 2nd to 3rd mitoses were sensitive periods in the presence of spermatozoal oxidative stress. Embryos that displayed either too long or too short cytokineses demonstrated an increased failure to reach blastocyst stage and therefore survive for further development. Although paternal-derived gene expression occurs later in development, this study suggests a specific role in early mitosis that is highly influenced by paternal factors.

Reflections on a half century of injury control.

1994-01-01

Using both historical analysis and personal reminiscence, this article describes the development of injury control activities since about 1940, focusing particular attention on the rise and fall of the Public Health Service's Division of Accident Prevention. By the 1940s and 1950s, modest but useful efforts in injury control research and programming had been made. The 1960s and early 1970s then saw an explosion of new concepts, programs, and enthusiasm, but much of this soon dissipated. Since 1985 there has been a renaissance of interest and effort, and the development of a new cadre of injury control professionals. This progress is threatened, however, by both old and new problems.

The link between early onset drinking and early onset alcohol-impaired driving in young males.

2014-05-01

Young drivers represent a disproportionate number of the individuals involved in alcohol-impaired driving. Although there is a known association between drinking and alcohol-impaired driving in young drivers, the link between early onset drinking and early onset alcohol-impaired driving has not been explored. The present study aimed to assess this link along with potentially confounding factors. The assessment used a proportional hazards model with data collected from the Buffalo Longitudinal Study of Young Men, a population-based sample of 625 males at aged 16-19. Controlling for the effects of potentially relevant confounds, the early onset of drinking was the most influential factor in predicting the early onset of alcohol-impaired driving. Race and the early onset of other forms of delinquency also played a significant role in the early onset of alcohol-impaired driving. Preventing an early start of drinking among adolescents may be the most critical factor to address in preventing an early start of alcohol-impaired driving.

Isocyanate exposure was evaluated in 33 spray painters from 25 Washington State autobody shops. Personal breathing zone samples (n = 228) were analyzed for isophorone diisocyanate (IPDI) monomer, 1,6-hexamethylene diisocyanate (HDI) monomer, IPDI polyisocyanate, and three polyisocyanate forms of HDI. The objective was to describe exposures to isocyanates while spray painting, compare them with short-term exposure limits (STELs), and describe the isocyanate composition in the samples. The composition of polyisocyanates (IPDI and HDI) in the samples varied greatly, with maximum amounts ranging from up to 58% for HDI biuret to 96% for HDI isocyanurate. There was a significant inverse relationship between the percentage composition of HDI isocyanurate to IPDI and to HDI uretdione. Two 15-min STELs were compared: (1) Oregon's Occupational Safety and Health Administration (OR-OSHA) STEL of 1000 μg/m(3) for HDI polyisocyanate, and (2) the United Kingdom's Health and Safety Executive (UK-HSE) STEL of 70 μg NCO/m(3) for all isocyanates. Eighty percent of samples containing HDI polyisocyanate exceeded the OR-OSHA STEL while 98% of samples exceeded the UK-HSE STEL. The majority of painters (67%) wore half-face air-purifying respirators while spray painting. Using the OR-OSHA and the UK-HSE STELs as benchmarks, 21% and 67% of painters, respectively, had at least one exposure that exceeded the respirator's OSHA-assigned protection factor. A critical review of the STELs revealed the following limitations: (1) the OR-OSHA STEL does not include all polyisocyanates, and (2) the UK-HSE STEL is derived from monomeric isocyanates, whereas the species present in typical spray coatings are polyisocyanates. In conclusion, the variable mixtures of isocyanates used by autobody painters suggest that an occupational exposure limit is required that includes all polyisocyanates. Despite the limitations of the STELs, we determined that a respirator with an assigned protection factor of 25 or

1/48-scale model of an F-18 aircraft in Flow Visualization Facility (FVF)

NASA Technical Reports Server (NTRS)

1985-01-01

This image shows a plastic 1/48-scale model of an F-18 aircraft inside the 'Water Tunnel' more formally known as the NASA Dryden Flow Visualization Facility. Water is pumped through the tunnel in the direction of normal airflow over the aircraft; then, colored dyes are pumped through tubes with needle valves.

Background Young drivers represent a disproportionate number of the individuals involved in alcohol-impaired driving. Although there is a known association between drinking and alcohol-impaired driving in young drivers, the link between early onset drinking and early onset alcohol-impaired driving has not been explored. Objectives The present study aimed to assess this link along with potentially confounding factors. Methods The assessment used a proportional hazards model with data collected from the Buffalo Longitudinal Study of Young Men, a population based sample of 625 males at ages of 16–19 years old. Results Controlling for the effects of potentially relevant confounds, the early onset of drinking was the most influential factor in predicting the early onset of alcohol-impaired driving. Race and the early onset of other forms of delinquency also played a significant role in the early onset of alcohol-impaired driving. Conclusion Preventing an early start of drinking among adolescents may be the most critical factor to address in preventing an early start of alcohol-impaired driving. PMID:24766089

Following the second Sahelian famine in 1984–1985, major investments were made to establish Early Warning Systems. These systems help to ensure that timely warnings and vulnerability information are available to decision makers to anticipate and avert food crises. In the recent crisis in the Horn of Africa, alarming levels of acute malnutrition were documented from March 2010, and by August 2010, an impending food crisis was forecast. Despite these measures, the situation remained unrecognised, and further deteriorated causing malnutrition levels to grow in severity and scope. By the time the United Nations officially declared famine on 20 July 2011, and the humanitarian community sluggishly went into response mode, levels of malnutrition and mortality exceeded catastrophic levels. At this time, an estimated 11 million people were in desperate and immediate need for food. With warnings of food crises in the Sahel, South Sudan, and forecast of the drought returning to the Horn, there is an immediate need to institutionalize change in the health response during humanitarian emergencies. Early warning systems are only effective if they trigger an early response. PMID:22745628

[Exposure to solvents and tardy epilepsy: 2 clinical cases].

PubMed

Bernardini, P; Scoppetta, C

Organic solvents (OS) are widely used in industry and craft work. The neurotoxic effects of OS are well known in occupational exposure occurring in poor industrial hygiene conditions. There has been interest recently in a possible epileptogenic effect of OS exposure. Two cases are reported of late onset epilepsy observed in workers heavily exposed to OS. Case 1 was a 27-year-old male painter employed in a car body repair workshop. Solvent exposure was high for a few months because after his regular work, the man continued working as a car body painter in his own private concern. After a period of weakness and headache, probably indicating an excessive solvent absorption, he suffered two generalized paroxysmal seizures during sleep which necessitated hospitalization and continuous treatment with barbiturates. Case 2 was a 44-year-old male painter in a road advertising billboard factory who was continuously exposed to OS. Ten years previously he had been exposed to accidental massive inhalation of solvent vapours while opening a drum of solvents for coloured paint. Acute solvent poisoning followed and seven weeks later he suffered several epileptic episodes associated with typical EEG alterations; for many years, however, treatment was ineffective. In both cases there was neither a history of neurologic disease nor any other neurologic dysfunctions and the results of comprehensive neuroradiological studies were normal. Evidence exists of a chronological connection between high exposure to paint solvents and clinical evidence of late onset epilepsy, but it is not possible to identify a definite causal relationship.(ABSTRACT TRUNCATED AT 250 WORDS)

Exposures to 1,6-hexamethylene diisocyanate during polyurethane spray painting in the U.S. Air Force.

Carlton, G N; England, E C

2000-09-01

1,6-Hexamethylene diisocyanate (HDI) exposures were measured during polyurethane enamel spray painting at four Air Force bases. Breathing zone samples were collected for HDI monomer and polyisocyanates (oligomers) using three sampling methods: NIOSH Method 5521, the Iso-Chek sampler, and the total aerosol mass method (TAMM). Exposures to HDI monomer are low when compared to current occupational exposure limits; the highest 8-hr time-weighted average (TWA) exposure found was 3.5 micrograms/m3, below the American Conference of Governmental Industrial Hygienists (ACGIH) threshold limit value (TLV) of 34 micrograms/m3. HDI oligomer levels were higher; mean task exposures indicated by either the Iso-Chek sampler or TAMM are above the Oregon ceiling limit of 1 mg/m3. Eight-hour TWA exposures, however, were much lower, with only one exceeding the Oregon standard of 0.5 mg/m3. Poor worker practices commonly observed during this study included: standing in downwind positions so paint overspray passed through breathing zones; spraying toward other painters; and using excessive paint spray gun air cap pressures. Workers should stand in upwind orientation relative to the aircraft being painted, causing overspray to move away from the painter's breathing zone; adjust their position to prevent spraying other painters or limit paint application to one worker at a time; and use air cap pressure gauges prior to spraying to limit spray gun air cap pressures and reduce paint overspray generation rates. These improved techniques will result in reduced worker exposures to isocyanates.

Although urinary 1,6-hexamethylene diamine (HDA) is a useful biomarker of exposure to 1,6-hexamethylene diisocyanate (HDI), a large degree of unexplained intra- and inter-individual variability exists between estimated HDI exposure and urine HDA levels. We investigated the effect of individual and workplace factors on urine HDA levels using quantitative dermal and inhalation exposure data derived from a survey of automotive spray painters exposed to HDI. Painters' dermal and breathing-zone HDI-exposures were monitored over an entire workday for up to three separate workdays, spaced approximately one month apart. One urine sample was collected before the start of work with HDI-containing paints, and multiple samples were collected throughout the workday. Using mixed effects multiple linear regression modeling, coverall use resulted in significantly lower HDA levels (p = 0.12), and weekday contributed to significant variability in HDA levels (p = 0.056). We also investigated differences in urine HDA levels stratified by dichotomous and classification covariates using analysis of variance. Use of coveralls (p = 0.05), respirator type worn (p = 0.06), smoker status (p = 0.12), paint-booth type (p = 0.02), and more than one painter at the shop (p = 0.10) were all found to significantly affect urine HDA levels adjusted for creatinine concentration. Coverall use remained significant (p = 0.10), even after adjusting for respirator type. These results indicate that the variation in urine HDA level is mainly due to workplace factors and that appropriate dermal and inhalation protection is required to prevent HDI exposure.

Employment and educational outcomes in early intervention programmes for early psychosis: a systematic review.

Young adults with early psychosis want to pursue normal roles - education and employment. This paper summarises the empirical literature on the effectiveness of early intervention programmes for employment and education outcomes. We conducted a systematic review of employment/education outcomes for early intervention programmes, distinguishing three programme types: (1) those providing supported employment, (2) those providing unspecified vocational services and (3) those without vocational services. We summarised findings for 28 studies. Eleven studies evaluated early intervention programmes providing supported employment. In eight studies that reported employment outcomes separately from education outcomes, the employment rate during follow-up for supported employment patients was 49%, compared with 29% for patients receiving usual services. The two groups did not differ on enrolment in education. In four controlled studies, meta-analysis showed that the employment rate for supported employment participants was significantly higher than for control participants, odds ratio = 3.66 [1.93-6.93], p < 0.0001. Five studies (four descriptive and one quasi-experimental) of early intervention programmes evaluating unspecified vocational services were inconclusive. Twelve studies of early intervention programmes without vocational services were methodologically heterogeneous, using diverse methods for evaluating vocational/educational outcomes and precluding a satisfactory meta-analytic synthesis. Among studies with comparison groups, 7 of 11 (64%) reported significant vocational/education outcomes favouring early intervention over usual services. In early intervention programmes, supported employment moderately increases employment rates but not rates of enrolment in education. These improvements are in addition to the modest effects early programmes alone have on vocational/educational outcomes compared with usual services.

The renaissance of complement therapeutics

2018-01-01

The increasing number of clinical conditions that involve a pathological contribution from the complement system — many of which affect the kidneys — has spurred a regained interest in therapeutic options to modulate this host defence pathway. Molecular insight, technological advances, and the first decade of clinical experience with the complement-specific drug eculizumab, have contributed to a growing confidence in therapeutic complement inhibition. More than 20 candidate drugs that target various stages of the complement cascade are currently being evaluated in clinical trials, and additional agents are in preclinical development. Such diversity is clearly needed in view of the complex and distinct involvement of complement in a wide range of clinical conditions, including rare kidney disorders, transplant rejection and haemodialysis-induced inflammation. The existing drugs cannot be applied to all complement-driven diseases, and each indication has to be assessed individually. Alongside considerations concerning optimal points of intervention and economic factors, patient stratification will become essential to identify the best complement-specific therapy for each individual patient. This Review provides an overview of the therapeutic concepts, targets and candidate drugs, summarizes insights from clinical trials, and reflects on existing challenges for the development of complement therapeutics for kidney diseases and beyond.

MUC1, the renaissance molecule.

MUC1 is a large, heavily glycosylated mucin expressed on the apical surfaces of most simple, secretory epithelia including the mammary gland, gastrointestinal, respiratory, urinary and reproductive tracts. Although MUC1 was thought to be an epithelial-specific protein, it is now known to be expressed on a variety of hematopoietic cells as well. Mucins function in protection and lubrication of epithelial surfaces. Transmembrane mucins, which contain cytoplasmic tail domains, appear to have additional functions through their abilities to interact with many proteins involved in signal transduction and cell adhesion. The goal of this review is to highlight recent discoveries that suggest that MUC1 may be a multifunctional protein, located on the surfaces of cells as a sensor of the environment, poised to signal to the interior when things go awry.

Cardiac Fibroblast: The Renaissance Cell

PubMed Central

Souders, Colby A.; Bowers, Stephanie L.K.; Baudino, Troy A.

2012-01-01

The permanent cellular constituents of the heart include cardiac fibroblasts, myocytes, endothelial cells and vascular smooth muscle cells. Previous studies have demonstrated that there are undulating changes in cardiac cell populations during embryonic development, through neonatal development and into the adult. Transient cell populations include lymphocytes, mast cells and macrophages, which can interact with these permanent cell types to affect cardiac function. It has also been observed that there are marked differences in the makeup of the cardiac cell populations depending on the species, which may be important when examining myocardial remodeling. Current dogma states that the fibroblast makes up the largest cell population of the heart; however, this appears to vary for different species, especially mice. Cardiac fibroblasts play a critical role in maintaining normal cardiac function, as well as in cardiac remodeling during pathological conditions such as myocardial infarct and hypertension. These cells have numerous functions, including synthesis and deposition of extracellular matrix, cell-cell communication with myocytes, cell-cell signaling with other fibroblasts, as well as with endothelial cells. These contacts affect the electrophysiological properties, secretion of growth factors and cytokines, as well as potentiating blood vessel formation. While a plethora of information is known about several of these processes, relatively little is understood about fibroblasts and their role in angiogenesis during development or cardiac remodeling. In this review we provide insight into the various properties of cardiac fibroblasts that helps illustrate their importance in maintaining proper cardiac function, as well as their critical role in the remodeling heart.

Irrational "Coefficients" in Renaissance Algebra.

PubMed

Oaks, Jeffrey A

2017-06-01

Argument From the time of al-Khwārizmī in the ninth century to the beginning of the sixteenth century algebraists did not allow irrational numbers to serve as coefficients. To multiply by x, for instance, the result was expressed as the rhetorical equivalent of . The reason for this practice has to do with the premodern concept of a monomial. The coefficient, or "number," of a term was thought of as how many of that term are present, and not as the scalar multiple that we work with today. Then, in sixteenth-century Europe, a few algebraists began to allow for irrational coefficients in their notation. Christoff Rudolff (1525) was the first to admit them in special cases, and subsequently they appear more liberally in Cardano (1539), Scheubel (1550), Bombelli (1572), and others, though most algebraists continued to ban them. We survey this development by examining the texts that show irrational coefficients and those that argue against them. We show that the debate took place entirely in the conceptual context of premodern, "cossic" algebra, and persisted in the sixteenth century independent of the development of the new algebra of Viète, Decartes, and Fermat. This was a formal innovation violating prevailing concepts that we propose could only be introduced because of the growing autonomy of notation from rhetorical text.

Lesbian erotics: the utopian trope of Donne's "Sapho to Philaenis".

PubMed

Mueller, J

1992-01-01

Famous for its self-assertive masculinity, John Donne's love poetry nonetheless includes a verse elegy which stands alone not only in his work but also in the entire literary production of the Renaissance for its celebration and defense of a passionate lesbian relation binding the two women of its title. No editorial grounds exist for denying Donne's authorship of "Sapho to Philaenis"; rather the interpretive task is to reconstitute the poem's significance in period terms. The task is complicated by Donne's penchant for flouting literary and social convention as he successively overturns Ovid's influential portrayal of Sappho as an aging voluptuary reclaimed for heterosexuality, the virulent homophobia of Renaissance humanists, and the coy idealizations and transient evocation given to lesbian affectivity by the very few Renaissance writers (including Shakespeare) who touched on the subject at all. When "Sapho to Philaenis" is set in the context of Donne's other love elegies in verse as productions by a young intellectual moving in sophisticated London circles and writing for a coterie audience, lesbianism looks like a master trope for positively resolving a dilemma that confounded Montaigne and many other authors of the age. Could the perfections of love and friendship be united in a relation of equality between two persons? Gender hierarchy and separate socialization precluded a heterosexual construction of any such equality in the Renaissance, and the greater opprobrium cast on male homosexuality in this era must have influenced Donne's decision to figure his equal lovers and friends as a lesbian couple. Yet the disclosive power of "Sapho to Philaenis" goes far beyond the entailments of a specific choice of poetic representation. Donne really undertakes to imagine the pleasures, sustenance, and ideological implications by which lesbianism, as a mode of loving and being, resists patriarchal disposition and diminution of women. Donne anticipates the advances of

Biological aspects of early osteoarthritis.

Early OA primarily affects articular cartilage and involves the entire joint, including the subchondral bone, synovial membrane, menisci and periarticular structures. The aim of this review is to highlight the molecular basis and histopathological features of early OA. Selective review of literature. Risk factors for developing early OA include, but are not limited to, a genetic predisposition, mechanical factors such as axial malalignment, and aging. In early OA, the articular cartilage surface is progressively becoming discontinuous, showing fibrillation and vertical fissures that extend not deeper than into the mid-zone of the articular cartilage, reflective of OARSI grades 1.0-3.0. Early changes in the subchondral bone comprise a progressive increase in subchondral plate and subarticular spongiosa thickness. Early OA affects not only the articular cartilage and the subchondral bone but also other structures of the joint, such as the menisci, the synovial membrane, the joint capsule, ligaments, muscles and the infrapatellar fat pad. Genetic markers or marker combinations may become useful in the future to identify early OA and patients at risk. The high socioeconomic impact of OA suggests that a better insight into the mechanisms of early OA may be a key to develop more targeted reconstructive therapies at this first stage of the disease.

Disinhibited social engagement disorder (DSED) is poorly understood beyond early childhood. The course of DSED signs in a sample of children who experienced severe, early deprivation from early childhood to early adolescence was examined using variable-centered (linear mixed modeling) and person-centered (growth mixture modeling) approaches. The study included 124 children with a history of institutional care from a randomized controlled trial of foster care as an alternative to institutional care and 69 community comparison children matched by age and sex. DSED signs were assessed at baseline (mean age 22 months), 30, 42, and 54 months of age, and 8 and 12 years of age using a validated caregiver report of disturbed attachment behavior. Variable-centered analyses based on intent-to-treat groups indicated that signs of DSED decreased sharply for children randomized to foster care and decreased slightly but remained high for children randomized to care as usual. Person-centered analyses showed 4 profiles (i.e., elevated, persistent modest, early decreasing, and minimal). Elevated and persistent modest courses were associated with greater placement disruptions (F 3,99  = 4.29, p = .007, partial eta-squared [η 2 ] = 0.12), older age at placement into foster care (F 3,56  = 3.41, p < .05, partial η 2  = 0.16), and more time in institutional care (F 3,115  = 11.91, p < .001, partial η 2  = 0.24) compared with decreasing and minimal courses. Early and sustained placement into families after deprivation is associated with minimal or decreasing signs of DSED across development. Shortening the amount of time children spend in institutions and preserving placements could help decrease signs of DSED into early adolescence in previously institutionalized children.

Timing of Orphanhood, Early Sexual Debut, and Early Marriage in Four Sub-Saharan African Countries

According to a growing body of literature, some orphans are at heightened risk of early sexual debut and early marriage. This study examines a rarely explored aspect of orphanhood: the timing and type of parental death and their relationship to these outcomes. The study also explores whether education mediates orphans’ risk of early sexual initiation and early marriage. The data are drawn from the 2004 National Survey of Adolescents, which includes interviews with 12–19-year-old adolescents in Burkina Faso, Ghana, Malawi, and Uganda. Results from discrete-time event history analysis indicate that female double orphans, regardless of timing of orphanhood, have greater odds of early sexual debut than do nonorphans. Education explains little of their increased risk. In contrast, male orphans of any type reveal no increased vulnerability to early sexual debut. Uganda is the only country where female orphans, specifically double orphans and those who are paternal orphans before age 10, have greater odds of early marriage, with education accounting for a small portion of the risk.

Guided by a bridging model of pathways leading to low-income boys’ early-starting and persistent trajectories of antisocial behavior, the current paper reviews evidence supporting the model from early childhood through early adulthood. Using primarily a cohort of 310 low-income boys of families recruited from WIC centers in a large metropolitan area followed from infancy to early adulthood, and smaller cohorts of boys and girls followed through early childhood, we provide evidence supporting the critical role of parenting, maternal depression, and other proximal family risk factors in early childhood that are prospectively linked to trajectories of parent-reported conduct problems in early and middle childhood, youth-reported antisocial behavior during adolescence and early adulthood, as well as court-reported violent offending in adolescence. The findings are discussed in terms of the need to identify at-risk boys in early childhood and methods and platforms for engaging families in health care settings not previously used to implement preventive mental health services.

Early cosmology constrained

We investigate our knowledge of early universe cosmology by exploring how much additional energy density can be placed in different components beyond those in the ΛCDM model. To do this we use a method to separate early- and late-universe information enclosed in observational data, thus markedly reducing the model-dependency of the conclusions. We find that the 95% credibility regions for extra energy components of the early universe at recombination are: non-accelerating additional fluid density parameter ΩMR < 0.006 and extra radiation parameterised as extra effective neutrino species 2.3 < Neff < 3.2 when imposing flatness. Our constraints thus show that even when analyzing the data in this largely model-independent way, the possibility of hiding extra energy components beyond ΛCDM in the early universe is seriously constrained by current observations. We also find that the standard ruler, the sound horizon at radiation drag, can be well determined in a way that does not depend on late-time Universe assumptions, but depends strongly on early-time physics and in particular on additional components that behave like radiation. We find that the standard ruler length determined in this way is rs = 147.4 ± 0.7 Mpc if the radiation and neutrino components are standard, but the uncertainty increases by an order of magnitude when non-standard dark radiation components are allowed, to rs = 150 ± 5 Mpc.

Redefining early gastric cancer.

Barreto, Savio G; Windsor, John A

The problem is that current definitions of early gastric cancer allow the inclusion of regional lymph node metastases. The increasing use of endoscopic submucosal dissection to treat early gastric cancer is a concern because regional lymph nodes are not addressed. The aim of the study was thus to critically evaluate current evidence with regard to tumour-specific factors associated with lymph node metastases in "early gastric cancer" to develop a more precise definition and improve clinical management. A systematic and comprehensive search of major reference databases (MEDLINE, EMBASE, PubMed and the Cochrane Library) was undertaken using a combination of text words "early gastric cancer", "lymph node metastasis", "factors", "endoscopy", "surgery", "lymphadenectomy" "mucosa", "submucosa", "lymphovascular invasion", "differentiated", "undifferentiated" and "ulcer". All available publications that described tumour-related factors associated with lymph node metastases in early gastric cancer were included. The initial search yielded 1494 studies, of which 42 studies were included in the final analysis. Over time, the definition of early gastric cancer has broadened and the indications for endoscopic treatment have widened. The mean frequency of lymph node metastases increased on the basis of depth of infiltration (mucosa 6% vs. submucosa 28%), presence of lymphovascular invasion (absence 9% vs. presence 53%), tumour differentiation (differentiated 13% vs. undifferentiated 34%) and macroscopic type (elevated 13% vs. flat 26%) and tumour diameter (≤2 cm 8% vs. >2 cm 25%). There is a need to re-examine the diagnosis and staging of early gastric cancer to ensure that patients with one or more identifiable risk factor for lymph node metastases are not denied appropriate chemotherapy and surgical resection.

Early psychosis workforce development: Core competencies for mental health professionals working in the early psychosis field.

The aim of this study was to identify the core competencies required of mental health professionals working in the early psychosis field, which could function as an evidence-based tool to support the early psychosis workforce and in turn assist early psychosis service implementation and strengthen early psychosis model fidelity. The Delphi method was used to establish expert consensus on the core competencies. In the first stage, a systematic literature search was conducted to generate competency items. In the second stage, a panel consisting of expert early psychosis clinicians from around the world was formed. Panel members then rated each of the competency items on how essential they are to the clinical practice of all early psychosis clinicians. In total, 1023 pieces of literature including textbooks, journal articles and grey literature were reviewed. A final 542 competency items were identified for inclusion in the questionnaire. A total of 63 early psychosis experts participated in 3 rating rounds. Of the 542 competency items, 242 were endorsed as the required core competencies. There were 29 competency items that were endorsed by 62 or more experts, and these may be considered the foundational competencies for early psychosis practice. The study generated a set of core competencies that provide a common language for early psychosis clinicians across professional disciplines and country of practice, and potentially are a useful professional resource to support early psychosis workforce development and service reform. © 2017 John Wiley & Sons Australia, Ltd.

Early onset of smoking is associated with subsequent abuse of other substances and development of negative health outcomes. This study aimed to examine early life predictors of onset of smoking in an Australian young cohort. Data were from the Mater Hospital and University of Queensland Study of Pregnancy (MUSP), a population-based prospective birth cohort study (1981-2012). The present study is based on a cohort of 3714 young adults who self-reported smoking status and age of onset of smoking at the 21-year follow-up. Of these, data were available for 3039 on early childhood factors collected between the baseline and 14-year follow-up of the study. Of 3714 young adults, 49.6% (49.9% males and 49.3% females) reported having ever smoked cigarettes. For those who had ever smoked, mean and median ages at first smoke were 15.5 and 16.0years, respectively. In multivariate Cox proportional hazard analysis mother's education, change in maternal marital status, maternal cigarette smoking and alcohol consumption, maternal depression and child externalizing when the child was 5years statistically significantly predicted early onset of smoking. The data suggest that individuals exposed to personal and environmental risk factors during the early stage of childhood are at increased risk of initiation to cigarette smoking at an earlier age. Identification of the pathways of association between these early life factors and initiation to cigarette smoking may help reduce risk of tobacco smoking in adolescents and its adverse consequences.

Lead poisoning, the oldest recognized occupational disease, remains a danger for children and adults. Data collected for 664 cases reported to the Massachusetts Occupational Lead Registry in 1991-1995 were summarized in a 1998 state report. Here, the authors present some of the key findings from that report for a wider audience. The authors summarize key findings of the 1998 state report. Construction workers, in particular licensed deleaders and house painters, accounted for almost 70% of occupational cases involving blood lead levels > or = 40 micrograms of lead per deciliter (mcg/dl) of blood. Among 100 workers with the highest blood lead levels (> or = 60 mcg/dl), 29% were house painters. Hispanic workers were over-represented in the Registry. A small proportion of cases were non-occupational, typically associated with recreational use of firing ranges or do-it-yourself home renovations. Lead poisoning is a preventable disease, yet these data indicate that additional prevention efforts are warranted.
