When I lived near London, I fell in love with the The Arnolfini Portrait by Jan van Eyck in the National Gallery. One famously cool element of the painting is the way he included his own self-portrait in the convex mirror hanging behind the couple whose portrait he had painted. (For a closer look, and a very interesting theory on how optical depth of field may have influenced art history, see this article. Scroll down half-way for detail on the Arnolfini.)
A little while later, I saw and fell in love with Parmigianino's Self-Portrait in a Convex Mirror.
One morning at breakfast I was fiddling with my spoon and noticed that the highly reflective surface made a great convex mirror. I rounded up a few props, set my camera on a tripod, put the lens in macro mode, used a shutter release cable . . . .
Ostomy surgery results in an opening in the abdominal wall to make way for a surgically created diversion in the excretory pathway to evacuate bodily waste. That opening is known as the stoma. The bodily waste expelled by an #ostomy through the stoma is commonly referred to as the stomal output. A healthy stoma is deep red, and it looks much like the inside of the mouth. It protrudes from the abdominal skin by a few centimeters. When you wear an ostomy bag, the skin barrier of the bag fits over the stoma by letting it pass through a hole in the flange. The skin barrier sticks with the skin using an adhesive.
The recessed stoma
A healthy stoma is a bit protruded to allow the skin barrier to come in contact with the entire peristomal surface. However, a stoma might recess or retract to seem like dipping into the abdominal skin. That’s where it becomes impossible for conventional skin barriers to make a proper seal with the peristomal skin. If you try to wear an ostomy bag, the recessed stoma will not reach the inside of the ostomy bag. That can cause the stomal output to seep under the skin barrier and leak through the outside edges. The ostomy pouch will not be able to hold the skin for long. The contact of stomal output will result in irritation in the #peristomal skin.
Convex wafer
If you have a recessed #stoma and you are not willing to go for another surgical process for stoma repositioning, you can consider using an ostomy pouch with the convex wafer. The convex wafer comes with an inward curve towards the stoma. This curve pushes the peristomal skin, allowing the stoma to reach the inside of the ostomy bag. The secure fit around the stoma prevents the stomal output from reaching under the skin barrier or wafer.
A convex wafer can be a part of a one-piece or two-piece ostomy pouch. It can also be used with both the closed and drainable ostomy bags.
It would be worth mentioning here that if you do not face the issue of the recessed stoma or uneven peristomal skin, you should not use a convex wafer without a piece of advice from your doctor. Convexity can result in pressure on the peristomal skin, increasing the possibility of pressure ulcers. Moreover, it can be a challenge to choose a convex wafer with the required convexity. A discussion with your doctor can be a source of knowledge for you in this regard. You will be able to know whether or not a convex wafer is a right option for you.

Anyone who has poked around my woodworking photos for a while knows I like to laminate different types of wood together to create a unique pattern for most of the things I make. The series of woods I used here was something I put together for a special project I made my father a few years ago (a bedside caddy for his glasses and keys). What you see here is the inverse of that caddy, repurposed for those dark winter nights ahead.
This candle holder is made of alternating sequences of walnut and maple, with a strip of mahogany near the center for color. It'll hold three standard candlesticks (tapers) and the bottom is lined with felt, so it won't scratch up anybody's tabletop. The whole piece has been sanded down smooth to accentuate the gracious curved top, and it's been finished with several coats of glossy clear enamel, to maintain a carefree shine that'll stand up to repeated use.
I'm offering this in my online shop (smilemoon.etsy.com), so feel free to head over there if you're interested. Thanks for checking it out!

De la Simca Neuf à l’Aronde
"C'est le jeudi 31 mai 1951 qu'est dévoilée à la presse spécialisée la nouvelle berline Simca Neuf, plus connue sous le nom d'Aronde. Cette nouvelle, dans les deux sens du terme, fait littéralement I’ effet d’une bombe dont I’ aronde de choc se ressent jusqu'à Bobigny
Dès 1953, Meccano s'empresse ainsi d'en sortir une copie au 1/43. La miniature, mesurant 95 millimètres, est réalisée d'une seule pièce en zamak et possède, comme toutes ses consœurs, un plancher en tôle riveté. Les roues, convexes, sont toujours chaussées de pneumatiques blancs.
Sous la référence 24 U.
Meccano produit en fait deux modèles bien distincts.
Le premier type se reconnaît à sa calandre anguleuse ainsi qu'à sa carrosserie et ses roues peintes en gris clair, vert olive moyen ou vert olive foncé.
Le deuxième type possède une calandre allongée conforme à celle adoptée par Simca au salon d’octobre 1953.
Deux variantes de finition de peinture sont utilisées sur ce modèle équipé invariablement de roues chromées La première est uniformément gris clair, gris verdâtre ou bleu ciel tandis que la seconde est bleu ciel avec un toit ivoire, bleu moyen avec un toit ivoire et gris clair avec un toit vert foncé avec des nuances assez prononcées.
Cette dernière version est produite jusqu'en 1959 année où elle reçoit la référence 536."

Simca Aronde
From Wikipedia, the free encyclopedia
"The Simca Aronde is an automobile which was manufactured by the French automaker Simca from 1951 to 1963.
It was Simca's first original design (earlier models were all to a greater or lesser extent based on Fiats), as well as the company's first unibody car.
"/ Aronde -hirondelle" means "swallow" in Old French and it was chosen as the name for the model because Simca's logo at that time was a stylized swallow."
The three generations
"There were three generations of the model: the 9 Aronde, made from 1951 to 1955, the 90A Aronde, made from 1955 to 1958, and the Aronde P60 , which debuted in 1958 and continued until the model was dropped in 1964.
Some 1.4 million Arondes were made in total, and this model alone is largely responsible for Simca becoming the second-biggest French automaker at the end of the 1950s."
- Simca 9 Aronde (1951–1955)
"The first Aronde debuted in the spring of 1951 but initially only a few hundred pre-production cars were distributed to carefully selected "guinea-pig" buyers, and the full production version was finalised only in time for the Paris Motor Show, becoming available for sale in October 1951.
The full production version incorporated various detailed changed when compared to the pre-volume production cars, including a changed material for the seat covers and a moulded plastic dash-board which at the time appeared very modern when compared to the metal dashboard on the Aronde's most obvious competitor, the Peugeot 203.
A few months later, at the start of 1952, space was found to position the battery under the bonnet/hood: in the original cars the battery was stowed under the front seat.
The Aronde was fitted with a front-mounted 1221 cc 44.5 bhp (33.2 kW) engine from the previous Simca model, the Simca 8, fuel feed being provided by a Solex 32 carburetor. Power was delivered to the rear wheels via a traditional four-speed manual gear box incorporating synchromesh on the top three ratios. The car had independent suspension at the front using coil springs, with a live axle at the rear, suspended using semi-elliptic leaf springs. Hydraulically operated 9.85 in (250 mm) drum brakes were used all round.
The only body style offered at the October 1951 launch was a four-door saloon/sedan/berline, but other configurations very soon became available such as the three-door estate (branded initially as the "Aronde commerciale" and later as the "Châtelaine") with a horizontally split tailgate.
There was also a van, called the "Messagère", and a "commerciale semi-vitrée" - part panel van and part estate - became available in 1953.
Of more interest to collectors is the two-door coupé coachbuilt by Facel. The Facel-built coupé was replaced for 1953 by a coupé based on the saloon Aronde body, called Grand Large, featuring a large three piece wrap-around rear window and a "pillarless" side window effect when both side windows were wound down.
A two-door cabriolet conversion, prepared by the coachbuilder Figoni, was presented to the public for the 1953 model year in a display involving ballerinas, but it proved impossible to confer sufficient structural rigidity on this car without unacceptable cost and weight penalties, and Figoni's Aronde cabriolet was never produced for sale.
(...)
The 9 Aronde was well received, especially in France. It took only until 17 March 1953 before total production of this model at the Nanterre plant passed 100,000.
The company's flamboyant boss. Henri Pigozzi, was keenly aware of the publicity that could be gleaned from the craze for record breaking runs.
In May 1952 an Aronde broke five international records by covering a distance of 50,000 km (31,000 mi) at an average speed of 117 km/h (73 mph), and in August 1953 another Aronde, selected at random from the production line, returned to the Montlhéry circuit for a new record attempt whereby during the course of forty days and forty nights the car covered 39,242 laps which represented 100,000 km (62,000 mi) at an average speed of more than 104 km/h (65 mph).
This achievement, which involved breaking more than 30 international records, was undertaken under the supervision of the ACF."

BODEGAS YSIOS. Finca de Carravacas. Laguardia. Rioja alavesa. Álava
Arquitecto: Santiago Calatrava: 1998-2001
Ysios evoca el mundo mágico de Ysis, la diosa egipcia que velaba por el cuidado del proceso de transformación de la uva en vino. La bodega se sitúa en la mejor zona de Laguardia (Rioja Alavesa) con la Sierra de Cantabría de fondo. Una gran escultura integrada entre viñedos, una delicada silueta alada que remonta el vuelo. Pensada, a través de una arquitectura singular tan en boga en la nuevas bodegas -que rivalizan en la contratación de arquitectos de prestigio para singularizar sus nuevas construcciones-, tanto para la mejora del proceso de elaboración del vino, como para hacerlo atractivo y servir de foco de captación de visitantes
Se conforma mediante dos muros portantes de hormigón armado, separados 26 metros, revestidos por lamas verticales de madera tratada con sales de cobre. Los muros, de planta sinusoidal y una longitud total de 196 metros, se rematan superiormente por dos líneas también sinusoidales, frontalmente desplazadas, que generan, para la cubierta, una superficie reglada ondulada a modo de sucesión de conoides, combinando superficies cóncavas y convexas, a lo largo del eje longitudinal. Calatrava adoptó la estrategia de dar un tratamiento volumétrico a todas las fachadas, cubierta incluida, - límites físicos del paisaje exterior y dentro de la bodega - de modo que la continuidad entre ambos espacios se logra a través del "movimiento estático" de los recintos. La cubierta está formada por vigas de madera laminada que apoyan sobre los muros laterales, y se acaba exterior en aluminio, contrastando con el tratamiento en madera del resto del edificio. La fachada principal, sur, es ciega, salvo en su cuerpo central, donde se sitúa el Centro de Visitantes, que presenta un singular mirador de madera tanto hacia el interior de la bodega como al exterior, sobre los viñedos y el pueblo de Laguardia al fondo. Está revestida con listones de cedro colocado horizontalmente, y se acompaña, a ras de suelo, de dos láminas de agua, forradas con azulejo de color blanco en trencadís, que reflejan los muros aparentando de grandes toneles. La fachada norte es de paneles prefabricados de hormigón con estrechas aberturas. Las fachadas laterales, por las que se accede al proceso lineal de producción, están chapadas en placas de aluminio
Funcionalmente el edificio se ajusta al proceso lineal de fabricación, envejecimiento y embotellado del vino, mediante un pabellón alargado en el que la uva entra por uno de los lados, pasa por distintos procesos de prensado, decantado, reposo y envejecimiento, y acaba en el embotellado y almacenaje, correspondiéndose la zona central, la más representativa, accesible visualmente desde el recinto destinado a Centro de Visitantes, con el envejecimiento en barricas de madera.
A Claude glass (or black mirror) is a small mirror with a clear convex surface and the reverse side tinted a dark color. They were used by artists to reflect a landscape view in miniature, merging details and reducing subtleties of color so that the artist is presented with a nicely framed “picture” of a selected scene, one having a soft and pleasing tonal harmony. Claude glasses have the effect of abstracting the subject reflected in it from its surroundings, reducing and simplifying the color and tonal range of scenes and scenery to give them a painterly quality
Bound up like a pocket-book or packed in a protective carrying case, Claude glasses were used by artists, travelers, and connoisseurs of landscape and landscape painting. They were famously used by picturesque artists in England in the late 18th and early 19th centuries as a framing device for drawing sketches of picturesque landscapes. The user would turn his back on the scene to observe the framed view through the tinted mirror—in a sort of pre-photographic lens—which added the picturesque aesthetic of a subtle gradation of tones. Father Thomas West in his A Guide to the Lakes (1778) explained "The person using it ought always to turn his back to the object that he views. It [the mirror] should be suspended by the upper part of the case…holding it a little to the [viewer’s] right or the left (as the position of the parts to be viewed require) and the face screened from the sun."
The Claude glass is so called after Claude Lorrain, a 17th-century French landscape painter, whose name in the late 18th century became synonymous with the picturesque aesthetic. The Claude glass was supposed to help artists produce works of art similar to those of Claude Lorrain. Reverend William Gilpin, who popularized the picturesque ideal, advocated the use of a Claude glass, saying, "they give the object of nature a soft, mellow tinge like the colouring of that Master".
Use of Claude glasses became something of a mania among tourists and amateur artists, who quickly became the targets of satire. The whole notion of facing away from nature to experience a reduced reflection turned the Claude glass into a metaphor of artificiality. Hugh Sykes Davies wryly observed that users facing away from the object they wished to paint were actually turning their backs on it: "It is very typical of their attitude to Nature that such a position should be desirable”. (One could say similar things about people caught up in today’s mania for taking “selfies” in front of natural marvels and historic monuments, intruding themselves in front of those marvels and monuments rather than taking time to appreciate them in their own right.)

En los diferentes tipos de botellas de vino podemos encontrar el fondo convexo o Push Up y no es nada raro que alguien se pregunte para qué tiene que ser el fondo así.
En “Mitos del Vino: 6 típicos mitos del vino” comentamos que estas botellas no necesariamente determinan la calidad del vino, percepción posiblemente debida a que los productores que las eligen deben invertir un poco más en ellas. Las razones tienen que ver con su manufactura, características físicas y funcionalidad.

Key identification features
Identification should be made using a combination of features as some elements may vary.
Tritia reticulata
1. Maximum height 30mm.
2. Spire variably slender, flat-sided, sharply pointed cone with almost flat whorls on spire and shallow suture 1Tr flic.kr/p/2hF1X7i (body whorl convex). Juveniles are more squat, taper more sharply and may have slightly concave-sided spire 2Tr flic.kr/p/2hF31A1.
3. Smooth protoconch, c.1mm diameter, often persists to form a fine, sharp apex 8Tr flic.kr/p/2hF2ZuP , even when worn10Tr flic.kr/p/2hEYcvS .
4. Costae (axial ribs) intersect with spiral ridges to create reticulate arrangement of squarish bosses 7Tr flic.kr/p/2hEYcFB . In Britain, number of costae on body whorl is 15 to 23 (pers. obs. IFS, 2019), [15 to 20 (Jeffreys, 1867)], and, in Ria de Vigo, Spain, 16 to 23 (Rolan and Luque, 1994).
5. The final costa is rarely sufficiently thickened to form even a slight labial varix 4Tr flic.kr/p/2hEYddy .
6. Teeth within the outer (palatal) lip unevenly sized, 1 or 2 near middle often most prominent 12Tr flic.kr/p/2hF2Zpi . “inner lip - - is more or less tuberculated” (Jeffreys, 1867) (teeth/small ribs may be absent, especially on young ones).
7. When live and unworn, brown periostracum covers shell except protoconch and white rim of outer (palatal) lip 5Tr flic.kr/p/2hEYcRG . When periostracum removed, shell exterior is matt whitish/buff 7Tr flic.kr/p/2hEYcFB , unless stained by epizooic growth or other matter16Tr flic.kr/p/2hF1V5C . Interior is glossy white 3Tr flic.kr/p/2hF31sa .
8. Semicircular, glossy, opaque, white parietal lip covers large part of body whorl 12Tr flic.kr/p/2hF2Zpi ; may be stained by epizooic growth or other matter16Tr flic.kr/p/2hF1V5C .
9. White columella and siphonal canal. No dark spot within canal 3Tr flic.kr/p/2hF31sa .
10. Siphonal canal meets palatal lip at slightly-acute or right angle when viewed end-on13Tr flic.kr/p/2hF1VqY . [Beachworn specimens may have angle worn to obtuse and resemble T. nitida 37Tr flic.kr/p/2hF69i4 .]
11. 4 to 5 grooves on columellar neck of siphonal canal 7Tr flic.kr/p/2hEYcFB [Often worn away, so use 4 or 5 to confirm T. reticulata; but those with 3, fewer or none may be either T. nitida or worn T. reticulata11Tr flic.kr/p/2hF1VBE & 38Tr flic.kr/p/2hF559d .]
12. Body flesh light sienna (yellowish) 11Tr flic.kr/p/2hF1VBE (juveniles, whitish20Tr flic.kr/p/2hEYbJr ), heavily marked with small blotches of white and brown/black. Uncertain whether grey body only on T. nitida.
13. Egg capsules like a flat, circular brandy bottle that broadens with age 39Tr flic.kr/p/2hF68jk . Mean height 4.07mm, width 3.25mm (Rolan & Luque, 1994).
14. Sandy sediment sublittorally, and LWS on rocky shores with areas of sand, all round Britain and Ireland.
Similar species
Tritia nitida (Jeffreys, 1867)
WoRMS accepts T. nitida as a valid species; supported by chromotology (Collyer, 1961), comparative morphology (Rolan & Luque, 1994), allozymes (Sanjuan et al., 1997) and DNA (Couceiro et al., 2012) ,further detail at flic.kr/s/aHsmHvjqNk . Populations vary geographically, so some features may not match those below, which are marked (J) for Thames, Orwell and Roach estuaries in S.E. England in Jeffreys (1867); (B) for sample of 220 in 2019 from Blackwater estuary in S.E. England; (S) for Ria de Vigo, N.W. Spain in Sanjuan et al. (1997); (R) for Ria de Vigo in Rolan and Luque (1994) and (P) for northern Adriatic Italy and Croatia (J. Prkić, 2019, pers.comm. September 2019). So use a combination of features when making an identification.
1. Maximum height 25mm (J), exceptionally (2% of strandline sample) 26 to 30mm (B) 46Tr flic.kr/p/2hF659n , 30mm in Galicia, Spain (Trigo et al., 2018), 40mm in Italian Adriatic (P) 47Tr flic.kr/p/2hF64Ld .
2. Adult T. nitida spire-whorls convex in Essex 46Tr flic.kr/p/2hF659n & 48Tr flic.kr/p/2hF2hwY but may be less tumid in other parts of Britain and Ireland 49Tr flic.kr/p/2hF4Znp . Jeffreys (1867), stated “whorls flattened; - - suture deeper [than on T. reticulata]”. Compared to gastropods generally, the gentle convexity of the whorls on Essex T. nitida could be said to be flattish, but they are more convex than on T. reticulata, resulting in the deeper suture Jeffreys mentions. In the Adriatic, T. nitida whorls vary from convex to nearly flat 50Tr flic.kr/p/2hF63Tw .
3. Smooth protoconch is frequently worn/broken off to give a blunt apex 48Tr flic.kr/p/2hF2hwY (appears to persist more on Mediterranean T. nitida 50Tr flic.kr/p/2hF63Tw ).
4. In Britain, number of costae on body whorl is 10 to 14 B, [10 to 12,J]
In southern Europe T. nitida varies more widely, 11 to 19 (R), 9 to 18 (P), and overlaps with T. reticulata.
5. Labial varix on almost all shells over 15mm high (J, B, P) and additional varix on body whorl occasionally in Britain (J) 51Tr flic.kr/p/2hF63vn , and frequently in Adriatic (P) 50Tr flic.kr/p/2hF63Tw . In Britain the varix is usually less pronounced than on T. incrassata; sometimes little more than slightly thickened costae, and lost or inconspicuous on some beachworn strandline shells 52Tr flic.kr/p/2hF62Ww . Adriatic specimens can have very prominent varices 53Tr flic.kr/p/2hF62Mi & 54Tr flic.kr/p/2hF2fMW .
6. Teeth within the outer (palatal) lip quite evenly sized 55Tr flic.kr/p/2hF4XZE , sometimes one a bit higher. “inner [columellar/parietal] lip - - - never tuberculated” (J), but some Adriatic T. nitida have tubercles/teeth on the inner lip 55Tr flic.kr/p/2hF4XZE .
7. “epidermis [periostracum] inconspicuous 57Tr flic.kr/p/2hF4XKw , or obscured by an earthy incrustation 58Tr flic.kr/p/2hF4XDK ” (J). Shell exterior and interior 59Tr flic.kr/p/2hF4XvZ violaceous (R&S), purplish on yellowish white ground, raised sculpture yellowish white, and coloured lines 57Tr flic.kr/p/2hF4XKw brighter purple than on T. reticulata (J) but presence and intensity of purple varies greatly, often absent or, on beachworn shells, faded (B) 60Tr flic.kr/p/2hF4Xum .
8. In Britain, parietal lip translucent showing shell colour beneath (S & R) 48Tr flic.kr/p/2hF2hwY ; not as extensive, white or distinct as on T. reticulata, but strong and opaque on some T. nitida in Adriatic 53Tr flic.kr/p/2hF62Mi & 47Tr flic.kr/p/2hF64Ld . Sometimes eroded or stained on beachworn shells 48Tr flic.kr/p/2hF2hwY .
10. Siphonal canal meets palatal lip at obtuse angle when viewed end-on (R) 61Tr flic.kr/p/2hF4Xij . [Beachworn T. reticulata may have angle worn to obtuse and resemble T. nitida 52Tr flic.kr/p/2hF62Ww .]
11. Three grooves on columellar neck of siphonal canal 62Tr flic.kr/p/2hF61Ak but eroded from most strandline shells (75% B) and some live shells.
12.Jeffreys (1867) described the body of T. nitida as “greyish, with a slight tinge of purple, and closely speckled with flake-white”. This fits the Bretagne specimen at 63Tr flic.kr/p/2hF2ezL , presumably those from Essex where Jeffreys took his specimens, and some from the Adriatic 58Tr flic.kr/p/2hF4XDK , but some other Adriatic T. nitida have yellowish bodies 64Tr flic.kr/p/2hF61oB .The respiratory siphon is “almost always blackish” in Ria de Vigo (R) but both blackish and paler siphons occur on Adriatic T. nitida 58Tr flic.kr/p/2hF4XDK & 64Tr flic.kr/p/2hF61oB . The value of flesh and siphon colours for distinguishing T. nitida from T. reticulata elsewhere is uncertain.

OLYMPUS DIGITAL CCONVEX OR CONCAVE
Convex means curving out or extending outward.
Concave means curving in or hollowed inward.
So which one of these dangles have the crescents convex and which concave?
I would say both. Depends on your perspective. But what is true is one dangle is convex and the other is concave.
A fun pseudo lariat with beaded bead balls using CzechMates Crescents. The lariat is in two parts and the rope may be used on its own. The rope and connector takes advantage of the lovely drape created by the Russian Spiral. The beaded dangles themselves are woven with different counts of embellished prismatic right angle weave.

The scutellum is very convex covering the entire abdomen, dark blue with slight purple tint, almost black on naked eye. This beetle-backed fly is relatively larger than other celyphids, with a body length of about 8 mm.
Dr. Stephen Gaimari identified this as Paracelyphus, likely Paracelyphus hyacinthus.
I love the character of the building on the left, with its slightly concave right side and slightly convex left side.

De la Simca Neuf à l’Aronde
"C'est le jeudi 31 mai 1951 qu'est dévoilée à la presse spécialisée la nouvelle berline Simca Neuf, plus connue sous le nom d'Aronde. Cette nouvelle, dans les deux sens du terme, fait littéralement I’ effet d’une bombe dont I’ aronde de choc se ressent jusqu'à Bobigny
Dès 1953, Meccano s'empresse ainsi d'en sortir une copie au 1/43. La miniature, mesurant 95 millimètres, est réalisée d'une seule pièce en zamak et possède, comme toutes ses consœurs, un plancher en tôle riveté. Les roues, convexes, sont toujours chaussées de pneumatiques blancs.
Sous la référence 24 U.
Meccano produit en fait deux modèles bien distincts.
Le premier type se reconnaît à sa calandre anguleuse ainsi qu'à sa carrosserie et ses roues peintes en gris clair, vert olive moyen ou vert olive foncé.
Le deuxième type possède une calandre allongée conforme à celle adoptée par Simca au salon d’octobre 1953.
Deux variantes de finition de peinture sont utilisées sur ce modèle équipé invariablement de roues chromées La première est uniformément gris clair, gris verdâtre ou bleu ciel tandis que la seconde est bleu ciel avec un toit ivoire, bleu moyen avec un toit ivoire et gris clair avec un toit vert foncé avec des nuances assez prononcées.
Cette dernière version est produite jusqu'en 1959 année où elle reçoit la référence 536."

Simca Aronde
From Wikipedia, the free encyclopedia
"The Simca Aronde is an automobile which was manufactured by the French automaker Simca from 1951 to 1963.
It was Simca's first original design (earlier models were all to a greater or lesser extent based on Fiats), as well as the company's first unibody car.
"/ Aronde -hirondelle" means "swallow" in Old French and it was chosen as the name for the model because Simca's logo at that time was a stylized swallow."
The three generations
"There were three generations of the model: the 9 Aronde, made from 1951 to 1955, the 90A Aronde, made from 1955 to 1958, and the Aronde P60 , which debuted in 1958 and continued until the model was dropped in 1964.
Some 1.4 million Arondes were made in total, and this model alone is largely responsible for Simca becoming the second-biggest French automaker at the end of the 1950s."
- Simca 9 Aronde (1951–1955)
"The first Aronde debuted in the spring of 1951 but initially only a few hundred pre-production cars were distributed to carefully selected "guinea-pig" buyers, and the full production version was finalised only in time for the Paris Motor Show, becoming available for sale in October 1951.
The full production version incorporated various detailed changed when compared to the pre-volume production cars, including a changed material for the seat covers and a moulded plastic dash-board which at the time appeared very modern when compared to the metal dashboard on the Aronde's most obvious competitor, the Peugeot 203.
A few months later, at the start of 1952, space was found to position the battery under the bonnet/hood: in the original cars the battery was stowed under the front seat.
The Aronde was fitted with a front-mounted 1221 cc 44.5 bhp (33.2 kW) engine from the previous Simca model, the Simca 8, fuel feed being provided by a Solex 32 carburetor. Power was delivered to the rear wheels via a traditional four-speed manual gear box incorporating synchromesh on the top three ratios. The car had independent suspension at the front using coil springs, with a live axle at the rear, suspended using semi-elliptic leaf springs. Hydraulically operated 9.85 in (250 mm) drum brakes were used all round.
The only body style offered at the October 1951 launch was a four-door saloon/sedan/berline, but other configurations very soon became available such as the three-door estate (branded initially as the "Aronde commerciale" and later as the "Châtelaine") with a horizontally split tailgate.
There was also a van, called the "Messagère", and a "commerciale semi-vitrée" - part panel van and part estate - became available in 1953.
Of more interest to collectors is the two-door coupé coachbuilt by Facel. The Facel-built coupé was replaced for 1953 by a coupé based on the saloon Aronde body, called Grand Large, featuring a large three piece wrap-around rear window and a "pillarless" side window effect when both side windows were wound down.
A two-door cabriolet conversion, prepared by the coachbuilder Figoni, was presented to the public for the 1953 model year in a display involving ballerinas, but it proved impossible to confer sufficient structural rigidity on this car without unacceptable cost and weight penalties, and Figoni's Aronde cabriolet was never produced for sale.
(...)
The 9 Aronde was well received, especially in France. It took only until 17 March 1953 before total production of this model at the Nanterre plant passed 100,000.
The company's flamboyant boss. Henri Pigozzi, was keenly aware of the publicity that could be gleaned from the craze for record breaking runs.
In May 1952 an Aronde broke five international records by covering a distance of 50,000 km (31,000 mi) at an average speed of 117 km/h (73 mph), and in August 1953 another Aronde, selected at random from the production line, returned to the Montlhéry circuit for a new record attempt whereby during the course of forty days and forty nights the car covered 39,242 laps which represented 100,000 km (62,000 mi) at an average speed of more than 104 km/h (65 mph).
This achievement, which involved breaking more than 30 international records, was undertaken under the supervision of the ACF."

macro mondays: transformation
BODEGAS YSIOS. Finca de Carravacas. Laguardia. Rioja alavesa. Álava
Arquitecto: Santiago Calatrava: 1998-2001
Ysios evoca el mundo mágico de Ysis, la diosa egipcia que velaba por el cuidado del proceso de transformación de la uva en vino. La bodega se sitúa en la mejor zona de Laguardia (Rioja Alavesa) con la Sierra de Cantabría de fondo. Una gran escultura integrada entre viñedos, una delicada silueta alada que remonta el vuelo. Pensada, a través de una arquitectura singular tan en boga en la nuevas bodegas -que rivalizan en la contratación de arquitectos de prestigio para singularizar sus nuevas construcciones-, tanto para la mejora del proceso de elaboración del vino, como para hacerlo atractivo y servir de foco de captación de visitantes
Se conforma mediante dos muros portantes de hormigón armado, separados 26 metros, revestidos por lamas verticales de madera tratada con sales de cobre. Los muros, de planta sinusoidal y una longitud total de 196 metros, se rematan superiormente por dos líneas también sinusoidales, frontalmente desplazadas, que generan, para la cubierta, una superficie reglada ondulada a modo de sucesión de conoides, combinando superficies cóncavas y convexas, a lo largo del eje longitudinal. Calatrava adoptó la estrategia de dar un tratamiento volumétrico a todas las fachadas, cubierta incluida, - límites físicos del paisaje exterior y dentro de la bodega - de modo que la continuidad entre ambos espacios se logra a través del "movimiento estático" de los recintos. La cubierta está formada por vigas de madera laminada que apoyan sobre los muros laterales, y se acaba exterior en aluminio, contrastando con el tratamiento en madera del resto del edificio. La fachada principal, sur, es ciega, salvo en su cuerpo central, donde se sitúa el Centro de Visitantes, que presenta un singular mirador de madera tanto hacia el interior de la bodega como al exterior, sobre los viñedos y el pueblo de Laguardia al fondo. Está revestida con listones de cedro colocado horizontalmente, y se acompaña, a ras de suelo, de dos láminas de agua, forradas con azulejo de color blanco en trencadís, que reflejan los muros aparentando de grandes toneles. La fachada norte es de paneles prefabricados de hormigón con estrechas aberturas. Las fachadas laterales, por las que se accede al proceso lineal de producción, están chapadas en placas de aluminio
Funcionalmente el edificio se ajusta al proceso lineal de fabricación, envejecimiento y embotellado del vino, mediante un pabellón alargado en el que la uva entra por uno de los lados, pasa por distintos procesos de prensado, decantado, reposo y envejecimiento, y acaba en el embotellado y almacenaje, correspondiéndose la zona central, la más representativa, accesible visualmente desde el recinto destinado a Centro de Visitantes, con el envejecimiento en barricas de madera.
