Red caps versus black hats: the clothing issues of the 1675 revolt in the Cap Caval

En juillet 1675, dans l’actuel pays Bigouden, une assemblée de participants à la révolte dite des Bonnets Rouges décide d’envoyer des représentants devant les États de Bretagne pour y expliquer les raisons de la sédition. Les activistes prévoient de vêtir ces délégués selon un costume défini et fixé dans un écrit, le Règlement. Ce dernier existe en trois exemplaires, avec des divergences concernant la codification vestimentaire. Si les exemplaires issus des archives bretonnes évoquent un bonnet et camisole rouges et un haut-de-chausse bleu, celui qui a été retrouvé dans les archives de Colbert évoque aussi un bonnet et une camisole rouges mais prévoit des haut-de-chausses verts. L’étude des inventaires après décès et des signalements émanant des autorités judiciaires montre que le diocèse de Cornouaille s’est singularisé par une identité vestimentaire masculine composée d’un bonnet rouge, d’une camisole rouge et de hauts-de-chausses bleus-violets. Ces derniers commencent toutefois à être concurrencés par des vêtements à connotation citadine. La mise à l’écart de ces effets d’un genre nouveau d’une part et la remise à l’honneur du costume diocésain d’autre part permettent de comprendre la motivation des insurgés : celle d’un retour utopique à un idéal communautaire.

Substantial Improvement of Color-Rendering Properties of Conventional White LEDs Using Remote-Type Red Quantum-Dot Caps.

A new type of remote red quantum-dot (QD) component was designed and fabricated to improve the color-rendering properties of conventional white LED (light-emitting diode) lightings. Based on an optical simulation, the rectangular cavity-type QD cap was designed with an opening window on the top surface. Red QD caps were fabricated using a typical injection molding technique and CdSe/ZnS QDs with a core/shell structure whose average size was ~6 nm. Red QD caps were applied to conventional 6-inch, 15-W white LED downlighting consisting of 72 LEDs arrayed concentrically. The red QD caps placed over white LEDs enhanced the red components in the long-wavelength range resulting in the increase of the color rendering index (CRI) from 82.9 to 94.5. The correlated color temperature was tuned easily in a wide range by adopting various configurations consisting of different QD caps. The spatial and angular homogeneities were secured on the emitting area because QD caps placed over the white LEDs did not exhibit any substantial optical path length difference. The present study demonstrates that adopting QD caps in conventional LED lightings provides a flexible and efficient method to realize a high color-rendering property and to adjust correlated color temperature appropriately for a specific application.

Sources of Inspiration in the Early Life of Leonardo da Vinci

Although the early life of Leonardo da Vinci in Florence seems singularly unproductive, particularly considering the acknowledged breadth of his genius, an inferential examination of his early work reveals an interesting scope of likely activities. A self-referential element is his only signed and dated work, a landscape drawing, which is identified as a likely commemoration of the date of his conception in Vinci, a unique concept in art historical analysis. To develop a fuller picture of his accomplishments in this early period requires an interconnected series of analyses and reappraisals, including an interpretation of the otherwise puzzling set of young men in red caps painted by Botticelli as the incipiently famous group of artists that trained in Verrocchio’s bottega. These analyses fill out the picture of Leonardo’s formative years in the hillsides and towns around Vinci, as not only a precocious artist based on exposure to works by famous artists before leaving Vinci, but as a handsome studio model, an extempore musician, a leading member of the redcap band of remarkable apprentices in Medici Florence, an engineering assistant to his master Verrocchio, and a collaborative associate of the pioneering group of Florentine perspectivists including Uccello and Toscanelli in their later years.

Shape optimization of quantum-dot caps for high color-rendering white light-emitting diodes studied by optical simulation

Conventional white lightings based on light-emitting diodes (LEDs) lack deep red, which is responsible for their low color rendering index (CRI). To apply red quantum-dot (QD) caps is one way to improve the color-rendering property of white LEDs. Red QD caps were fabricated using CdSe/ZnS QDs in the acrylic resin matrix and applied to conventional white LED lighting, which clearly showed a significant increase in the CRI, especially R9 associated with the strong red. Optical simulation was carried out to find out the optimized structure of the QD caps. The CRI increased while the optical efficiency decreased as the color conversion efficiency increased, which suggested that there should be a compromise between the two properties. It was found that to form a non-absorbing optical cavity in the QD cap was an effective way to achieve high CRI values while maintaining a moderately good optical efficiency.

Taxonomy and Grafting of Ornamental Cacti: A Review

Nowadays, cacti and succulents are widely utilized in landscaping. These plants suit very effectively for both indoor and outdoor decorations. The family Cactaceae comprises of 130 genera with 2000 species and this is primarily divided into three tribes namely: Pereskieae, Opuntieae and Cereeae. Cactus flowers are very attractive and are diverse in size, number, form and color. The nocturnal flowers are always white, with light-yellow or red tones, whereas diurnal flowers are white, purple, yellow-orange, red or green. Basically, an areole is a transformed axillary bud situated over a tubercle with spines and often with hairs and trichomes. Due to their low maintenance requirements and their ability to withstand harsh environments, cacti are extremely popular as ornamental plants across the planet. Cacti can be propagated by seeds, cuttings, offsets and grafts. Grafted cacti are now regarded as one of the most admired ornamental indoor plants worldwide. In cacti, grafting has become a commercial method of propagation to accelerate and hasten the growth rate of slow growing species, to ensure the survival of the plants with poor root system, to ensure the survival of genetic aberration of variegated and bright coloured cacti (red and yellow caps) that lack chlorophyll, to accelerate the growth of plants for commercial use, in order to keep cristate and monstrose forms look attractive. Successful grafts have been obtained when the species like Trichocereus spachianus, Trichocereus macrogonus, Trichocereus pachanoi, Hylocereus trigonus, Hylocereus undatus, Selenicereus grandiflorus, Opuntia bergeriana, Opuntia ficus-indica are grafted onto Nopalea spp. The exogenous application of IBA has a positive effect on the vegetative growth of grafted plants using (Gymnocalycium mihanovichii scion grafted onto Trichocereus spachianus rootstock.

Little Burgundy: The Interwoven Histories of Race, Residence, and Work in Twentieth-Century Montreal

Until the 1950s, most black men in Montreal worked for the railway companies as sleeping car porters, dining car employees, and red caps. The city’s English-speaking black community took root in Little Burgundy because it was close to Windsor and Bonaventure train stations. The area between Saint-Henri and Griffintown, north of the Lachine Canal, in the city’s Southwest Borough, was once known by many names. “Little Burgundy” was invented in the 1960s by city officials to describe their urban renewal plans for the area. If employment mobility was foundational in making this community, it proved just as central in its unmaking in the 1960s and 1970s. The shift from trains to cars and trucks had a two-fold impact on Little Burgundy. First, employment levels collapsed with the decline of passenger train travel, leaving many black men unemployed. Then the state built a highway through the neighbourhood to facilitate the mobility of mainly white suburban workers and consumers making their way to the central city. Next, the neighbourhood was “renewed” on a massive scale. What followed were years of dislocation and crisis. Much of the black community was dispersed as a result. It was no coincidence. The radical restructuring of North American cities disproportionately affected racialized minorities and poor whites. What was different here was that the area’s reputation for being the birthplace of black Montreal emerged after the community had been largely dispersed by urban renewal.

The Red Cap’s Gift: How Tipping Tempers the Rational Power of Money

Modern people are obsessed with money, but the practice of tipping a waiter or chambermaid is a counterbalance against money’s tendency to infect human relations. People who tip infect money back, with nonmonetary values. This article provides a general history of tips investing money and monetary exchange with ideals such as status, dignity, waste, care, and play, in certain parts of the United States, c. 1880–1929. It also offers a case study of railroad red caps’ tips in the five years following passage of the Fair Labor Standards Act of 1938; when tipping declined, it reduced red caps’ ability to invest their work with nonmonetary values.

Accidental intra-arterial injection: an under-reported preventable never event

Depending upon the medication administered, accidental administration of medication into the arterial line can cause devastating complications. This wrong-route injection is a never event in the UK but may be under-reported especially when occurring in the unconscious patient who may not notice associated pain temporally. Under-reporting may occur because resultant complications may be delayed a number of hours and the accountable healthcare worker may not recognise or choose not to report the error. In 2008 the UK National Patient Safety Agency (NPSA) reported only 76 incidents related to poor sampling technique but few wrong route arterial injections. Of these 21% suffered moderate to severe harm [1]. The NPSA suggests that training and the use of clear labelling alongside red arterial tubing and standard red lock caps be used to prevent arterial sampling errors.

Novel concepts for preparation of reference materials as whole water samples for priority substances at nanogram-per-liter level using model suspended particulate matter and humic acids.

One of the unresolved issues of the European Water Framework Directive is the unavailability of realistic water reference materials for the organic priority pollutants at low nanogram-per-liter concentrations. In the present study, three different types of ready-to-use water test materials were developed for polycyclic aromatic hydrocarbons (PAHs), polybrominated diphenyl ethers (PBDEs) and tributyltin (TBT) at nanogram-per-liter levels. The first type simulated the dissolved phase in the water and comprised of a solution of humic acids (HA) at 5 mg L−1 dissolved organic carbon (DOC) and a spike of the target compounds. The second type of water sample incorporated the particulate phase in water. To this end, model suspended particulate matter (SPM) with a realistic particle size was produced by jet milling soil and sediments containing known amounts of PAHs, PBDEs and TBT and added as slurry to mineral water. The most complex test materials mimicked “whole water” consequently containing both phases, the model SPM and the HA solution with the target analytes strongly bound to the SPM. In this paper, the development of concepts, processing of the starting materials, characterisation of the HA and model SPMs as well as results for homogeneity and stability testing of the ready-to-use test materials are described in detail. Graphical Vials containing 0.5 g of model SPM, black caps for TBT, silver caps for PAH and red caps for PBDEs, respectively. Graphical Petri dishes with dried model SPMs; to the left 95.7 ± 0.9 mg of SPM containing PBDEs; in the middle 95.8 ± 0.7 mg of SPM containing TBT and to the right 93.7 mg ± 0.7 mg of SPM containing PAHs

Mates Exhibit Similar Brightness of Carotenoid Red Caps in Middle Spotted Woodpeckers Dendrocopos Medius

Most bird species display sexually dimorphic traits. In contrast to this general rule, both males and females of the Middle Spotted Woodpecker present a carotenoid red cap, which constitutes mutual ornamentation. In our study we investigated whether pair members are matched in terms of the brightness of this ornament. We also examined the similarity between mates in red cap size as well as biometric parameters, such as weight and the length of the wing, beak and tarsus. We found that males and females within pairs were positively assortatively mated with respect to the red cap brightness as well as body weight. We found no similarity between pair members neither in red cap size nor the length of wing, beak or tarsus. We discuss our findings in the light of mutual mate choice, social competitions and other factors that may account for the similarity in expression of the red cap in the studied species.

A bit of magic, sometimes helpful, sometimes sinister, runs through each of these thirteen short stories, most previously published, that all feature a gay or lesbian protagonist. The degree of focus on sexual orientation varies as much as the stories themselves: Cecil’s struggle to define his desires without labeling himself brings queerness to the forefront as he debates the significance of names with a silky-voiced Tooth Fairy in “Persimmon, Teeth, and Boys.” Another set of boys are brought together by a matchmaking yearbook. Saul’s affection for guys, however, takes a backseat during his encounter with sibling vampires in “All Smiles,” while Amelia’s clandestine relationship with Stephanie is ultimately the least of her worries after an infected bite drives her insane in “A Calenture of the Jungle.” Tales volley in tone from sweet, hopeful, and occasionally humorous (the script for an off-Broadway musical detailing the homoeroticism in Moby Dick is particularly amusing) to chilling, as when an older babysitting brother loses his charges to a vengeful ghost. The final story, directly addressing the reader, blends magical realism with just a bit of fairy tale in a quest that takes “you” through the shady underbellies of everyday closets and ultimately turns into a powerful and poignant coming-out story.

Mercury in Red Aspen Boletes (Leccinum aurantiacum) mushrooms and the soils

This communication reports data on the mercury contents of Red Aspen Boletes (Leccinum aurantiacum) mushrooms and the forest soils substrate layer (0–10 cm) underneath the fruit bodies collected from nine spatially distant sites across Poland. Total Hg concentration in soil substrate in seven of the nine sites studied varied from 0.0078 ± 0.0012 to 0.028 ± 0.007 μg/g dry weight (dw) and this could be considered baseline concentrations for uncontaminated forest soils in Poland. The arithmetic mean of mercury in Red Aspen Bolete caps varied, depending on the site from 0.27 ± 0.07 to 1.3 ± 0.6 μg/g dw. The lowest Hg contents in soil (0.011 ± 0.006 μg/g and 0.009 ± 0.002 μg/g) were observed for the sites of Wandalin and Opole Lubelskie (from Lubelska Upland region) with the corresponding highest bioconcentration factor (BCF) values of 130 ± 66 and 110 ± 13 for the mushroom caps and 58 ± 29 and 64 ± 8 for the stipes, respectively. The BCF values in caps showed a downward trend with increasing mercury content of soil. A meal of 300 g of fresh caps of Red Aspen Bolete from Aleksandrów Kujawski region could expose a consumer to 8.1 μg Hg, while this will be 39 μg at the Lubelska Upland amounting to 39 and 186 % of daily Hg reference dose, respectively.

Ultrastructure of Hepatozoon boigae (Mackerras, 1961) nov. comb. from brown tree snakes, Boiga irregularis, from northern Australia.

Intraerythrocytic bodies identified as haemogregarine gamonts were found in 29% of 97 brown tree snakes (Boiga irregularis) examined during a haematological survey of reptiles in Australasia during 1994-1998. The morphological characteristics of the parasites were consistent with those of Haemogregarina boigae Mackerras, 1961, although the gamonts were slightly larger and lacked red caps but contained distinctive polar grey capsules. Gamonts did not distend host cells but laterally displaced their nuclei. They were contained within parasitophorous vacuoles and possessed typical apicomplexan organelles, including a conoid, polar rings, rhoptries and micronemes. Schizonts producing up to 30 merozoites were detected in endothelial cells of the lungs of 11 snakes. The absence of erythrocytic schizogony suggests the parasites belong to the genus Hepatozoon. Electron microscopy also revealed the presence of curious encapsulated organisms in degenerating erythrocytes. These stages did not possess apical complex organelles and were surrounded by thick walls containing circumferential junctions and interposed strips reminiscent of oocyst sutures.
