Shell description
C. tubercularis grows up to 6.5 mm high. In profile it is a tall cone with convex sides. It has up to 14 whorls, including the protoconch. The body whorl forms 35-40% of the adult shell height 01Ct flic.kr/p/icR8pf . Juveniles have a shorter stouter cone; the body whorl is about 50% of the shell height on a 2 mm high shell 02Ct flic.kr/p/icR8jL . The nearly flat whorls of the teleoconch are glossy maroon to dark brown, and the sutures are in deep furrows. Each whorl of the teleoconch has three spiral rows of rectangular bead-like tubercles which are evenly spaced to give a square lattice appearance 03Ct flic.kr/p/icR8gj . The base of the body whorl below its periphery has a fourth darker, smooth or very slightly tuberculated, spiral band, and two or three inconspicuous whitish spiral riblets 01Ct flic.kr/p/icR8pf . The protoconch consists of the four apical whorls which form an elongate brownish apex; its whorls are moderately convex and smooth apart from microscopic granulation below the suture sometimes revealed by a scanning electron microscope. The protoconch, which remains the same absolute size at all growth stages, is largest relative to shell height on juvenile shells being about 34% of the height on a 1.4 mm high shell 04Ct flic.kr/p/icR8p5 . Beached strandline shells often have the protoconch damaged or lost. The small elliptical aperture is 20-25% of adult shell height and about 34% of a 1.4 mm high juvenile. There is a short siphonal canal at the base of the aperture 01Ct flic.kr/p/icR8pf & 08Ct flic.kr/p/icRgV1 . The palatal (outer) lip has a sharp, scalloped and strongly arched edge 09Ct flic.kr/p/icR82G . There is no umbilicus. The small, thin, oval, operculum is an incomplete spiral with an excentric nucleus near the basal edge. It is transparent colourless and shows a pair of yellow marks on the underlying opercular disc 05Ct flic.kr/p/icRh3W .
Body description
The short, slender, smooth, bluntly tipped cephalic tentacles each have an eye on the thickened base 06Ct flic.kr/p/icQUYT . There is no snout. Instead there is a small, black, opening 07Ct flic.kr/p/icQURt & 09Ct flic.kr/p/icR82G ventrally between the bases of the tentacles from which a slender acrembolic proboscis can be protruded. The slender, white respiratory siphon has a bifid tip 08Ct flic.kr/p/icRgV1 and rests in the much wider siphonal canal beyond which it does not protrude. The mantle is translucent whitish or whitish and grey like the body and shows the shell colour through it 09Ct flic.kr/p/icR82G . The foot is truncated at the front and tapers to blunt point at the posterior. It is usually extended well beyond the head and can fold across its middle at a transverse groove 09Ct flic.kr/p/icR82G . There is a pair of sulphur-yellow marks on the opercular lobe to which the operculum is attached 10Ct flic.kr/p/icR7MJ . There is a large anterior pedal gland in the widely bilaminate, broad, anterior of the foot 07Ct flic.kr/p/icQURt . The large circular opening of the pedal gland near the centre of the white sole 11Ct flic.kr/p/icQUMR , exudes copious mucus which is formed in a long deep medial groove into a support line for climbing among weed. The genital duct in both sexes is an open groove in the mantle cavity; there is no penis on males.
The ground colour of the body is translucent whitish with varying amounts of grey apart from on the pure white foot 12Ct flic.kr/p/icR7GJ . Frequently, there is a longitudinal band of sulphur-yellow 13Ct flic.kr/p/icR7FS or yellowish-white 09Ct flic.kr/p/icR82G opaque spots behind each eye, but it is sometimes absent 14Ct flic.kr/p/icRwGp . The amount and intensity of grey on the body varies from none 14Ct flic.kr/p/icRwGp to almost solid black 15Ct flic.kr/p/icR7Fb , and can even vary between left and right on the same animal 13Ct flic.kr/p/icR7FS . Often, there are three strong, grey, longitudinal bands between and flanking the tentacles 16Ct flic.kr/p/icQUtV .

4) Lives sublittorally, not on shore.
5) Feeds on Suberites domunculus (sponge). Flesh yellowish. No snout.
Cerithiopsis metaxa (della Chiaje, 1828)
1) Dextral shell to 8 mm high; very tall, slender, almost straight sided, yellowish or whitish with a short siphonal canal.
2) Four spiral ridges, 3 or 4 tuberculated, on penultimate whorl.
3) Base of final whorl lacks tubercles.

Several other species resemble C. tubercularis, but when the aperture is viewed with the apex uppermost, it is on the left (sinistral shell). They include Marshallora adversa and Monophorus perversus .
Habitat and ecology
C. tubercularis lives on shores at LWS, and sublittorally to about 100 m. It is a specialist feeder on the sponges Hymeniacidon perlevis (Montagu, 1814)
and Halichondria panicea (Pallas, 1766). To feed it everts a long fine proboscis and inserts it through a sponge’s osculum. Jaws in the proboscis tip loosen soft tissue which is raked back by the fine, long, claw-like teeth of radula to the buccal cavity. It favours sponges on rocks with tufts of red seaweed, such as Lomentaria and Corallina. The shell colour matches that of the weed, among which it climbs with the aid of mucus lines excreted from its pedal gland. It also eats debris and epiphytic and epizooic growths on the weed, especially when young.
It breeds in spring and summer. Males lack a penis and release 1 mm long spermatozeugmata into the water to swim in search of a female. Egg capsules, each containing a large number of minute eggs, are inserted into Hymeniacidon perlevis. Veliger larvae emerge to live in the plankton for a lengthy period during which they develop a long protoconch of four whorls 04Ct flic.kr/p/icR8p5 before settling and metamorphosing.
Distribution and status
C. tubercularis occurs from southern Norway to the Azores and eastern Mediterranean. GBIF map www.gbif.org/species/2301765 . It is recorded from Ireland and the south, west and north of Britain from Kent to Orkney. It is absent from the north-east Irish Sea and the North Sea coast of Britain between Kent and Orkney. It is occasionally common on the surface of intertidal or sublittoral Hymeniacidon perlevis. U.K. map NBN species.nbnatlas.org/species/NBNSYS0000174449

Clement came across Riblets great Instructable ( www.instructables.com/id/How_to_Build_Gears_from_Junkmail... ). Taking up his challenge and only a few minutes on the laser cutter he soon had a rather fun folding and gluing project. Folding and gluing done, you can see the results, a lovely and fun project. You can really feel how much time Riblet put into this and the end result is truly great.
Thanks for sharing Riblet.

Shark skin technology, Lufthansa Airbus A330-300 "Cuxhaven" D-AIKB makes a diversion into Dublin Airport while operating a Vancouver to Munich flight.
The German carrier has partnered with Airbus and the Fraunhofer Institute for Manufacturing Technology and Advanced Materials (IFAM) to test a new surface coating that mimics shark skin on two Airbus A330's.
It's part of a two-year long research project that started in the summer 2011, and will conclude this year.
The new technology mocks the riblet effect of a shark's skin in aircraft paints -- tiny riblets on the surface reduce flow resistance when moving at speed.
Yes, I know, I just made these a couple months ago and I hate repeats but they're too awesome to not eat frequently. Easy-peasy, not fatty and a marinade so good, I wish to lick the brush.
I didn't. Er, as far as you and our guest know, okay?
The band Man ... or Astro-Man? was ahead of its time - with retro, absurd as that may seem. They did retro so long ago, the word did not even exist yet. And today their early recordings, such as those united on this compilation CD, are old enough to be retro themselves.
Artwork adapted from this legendary German toy made by Markes & Co., Lüdenscheid in the late 1950s. See the Astroman in action here or get him on eBay if you are prepared to pay 2,000 US$ plus.

Janice (my partner of 32 years as of Aug. 20th) and I took the day off and went to the Griffith Observatory. We had a great time! Unfortunately my shots were crap, so I'll spare you the agony, except for one or two that are okay.
Sorry to all of my contacts for my absence from your streams. It's been a very hard summer. My mother at 87 going through quadruple bypass heart surgery, and then my wife two weeks ago choking on a large pill and barely able to breath and in the emergency room for five hours!

Chilecito La - Rioja
La Mina La Mejicana es una mina aurífera ubicada en el Cerro Famatina a 4.600 msnm (General Belgrano) a 34 km de la ciudad de Famatina en la provincia de La Rioja, Argentina.
Para transportar la gran cantidad de mineral hacia Chilecito se construyó lo que para la época era una de las mayores obras de ingeniería del mundo, el Cablecarril que fue terminado en 1905 con una longitud de 35 km y en la actualidad forma parte de los monumentos y lugares históricos de la Argentina.
Historia
Hacia finales del siglo XIX Famatina se convirtió en uno de los distritos más importantes con producción de oro, plata, hierro, cobre y plomo.
El cablecarril construido por capitales ingleses y fue impulsado por Joaquín Víctor González trasportaba 12.000 t mensuales de mineral desde la mina a Chilecito , luego era llevado en tren a los puertos con destino a Europa.
El auge de la mina se fue extinguiendo cuando comenzó la guerra de 1914 y los ingleses se retiraron. Otras empresas privadas continuaron con la explotación hasta 1926, año en que cesaron para siempre.
Actualmente el yacimiento se encuentra abandonado y sólo lo aprovecha el turismo geológico minero. Sin embargo, muchos geólogos afirman que el Cerro Famatina contiene importantes yacimientos, es así que empresas transnacionales están interesadas en explotar nuevos yacimientos, provocando en las localidades aledañas cierto rechazo por tales emprendimientos contaminantes.
El cablecarril
Estación II, salida hacia la Estación III. Vagonetas de transporte de mineral.
Para transportar los minerales hasta la fundición ubicada en Santa Florentina y hasta la ciudad de Chilecito donde se encontraba el ferrocarril, y para aprovisionar la mina, se construyó entre 1903 y 1905 un cablecarril que unía un trayecto de 34,3 km y y una diferencia de altura de 3.510 metros.
El cablecarril se componía de 8 tramos, unidos entre sí por 9 estaciones cada una de las cuales provee la tracción hacia el tramo siguiente mediante motores de vapor alimentados con leña, y un tramo adicional que conectaba la Estación II con la fundición de Santa Florentina. El tendido total incluyendo este tramo es de 35.128 metros.
Las dificultades en el transporte del mineral desde la mina, y de pertrechos en sentido contrario, debido a las distancias y las características del terreno motivaron la construcción del cablecarril que fue autorizado mediante Ley número 4208 del Congreso argentino, sancionada en noviembre de 1901. El 4 de enero del año siguiente el gobierno llama a licitación, a la que se presentan cinco empresas: Leschen and Sons Rope Co. (Saint Louis), Riblet Tramway Company, Spokane; Bullivan & Co. (Londres), Henderson & Co. (Londres), Ceretti & Tanfani (Turín), J. Pohlig & Co. (Colonia) y Adolf Bleichert & Co. (Leipzig).
La propuesta que finalmente obtiene el contrato es esta última, que es firmado el 31 de julio de 1902 por el Presidente Julio Argentino Roca, por un monto total de 217.988 pesos oro (monto que fuera modificado debido a cambios en el proyecto original).
El cablecarril tenía las siguientes características: la velocidad era de 2,5 m/s, contaba con 450 vagonetas separadas entre ellas por unos 112 metros, cada una con una carga de 500 kg y una capacidad de 0,3 m³. En algunos sitios la altura con respecto al suelo llegaba a 450 m.
Estación II, salida hacia la Estación I. Al fondo, la ciudad de Chilecito.
Cada estación está enlazada a la siguiente mediante un cable de sostén y un cable de tracción, sostenidos por torres ubicadas a intervalos regulares. Al llegar a cada estación, la vagoneta se desenganchaba del cable de tracción y se acoplaba al de la estación siguiente. El cable de soporte es de 32 mm y el de tracción, de 23 mm, ambos de acero, con enganches de plomo entre los tramos de cable. En total, hay 262 torres que tienen una altura entre 1 y 50 metros; se utilizaron 140 km de cable de acero, con 100 km de reserva.
Además del transporte de carga a granel, también había vagonetas especiales para el transporte de agua, combustible, alimentos, materiales de construcción y demolición, y personas. También existía una vagoneta especial de engrase y barnizado de los cables que llevaba a una persona, un depósito de lubricante y una bomba manual que permitía realizar esa tarea a medida que se recorría cada tramo.
Para la construcción del cablecarril trabajaron alrededor de 1.600 personas y se utilizaron animales de carga como medio de transporte, en particular, asnos y mulas, en promedio 90 asnos para el transporte de alimentos y 600 mulas para transporte de materiales de construcción. En la última fase de construcción, el Ejército Argentino facilitó 200 mulas de su cuerpo de artillería, llegando en esa época a ocuparse unos 1000 animales de carga.
La inauguración de los primeros tramos fue el 4 de julio de 1904 y la puesta en marcha el 1 de enero de 1905. El cablecarril terminó su actividad a fines de 1920. Fue puesto en marcha nuevamente entre las estaciones I y II con fines turísticos, pero la actividad fue rápidamente interrumpida luego de un accidente en el que dos personas perdieron la vida. Desde el año 2000 ha vuelto a funcionar entre esas estaciones a fines de mantenimiento.
En la actualidad (año 2010) se suelen hacer excursiones de turismo aventura a los restos de la mina y ascensos y descensos por lo que fue el camino del cablecarril.
Para los turistas inexpertos en montañismo, no se recomienda visitar la zona montañosa sin contratar un guía especializado.

The Red-shouldered Hawk, (Buteo lineatus), is a medium-sized hawk. Their breeding range is in eastern North America and along the coast of California and northern Mexico; also northeastern-central Mexico.
Males are 43 to 58 cm (17 to 23 in) long, weigh about 550 g (1.2 lbs) and have a wingspan of 96 cm (38 in). Females are slightly larger at 48 to 61 cm (19 to 24 in) in length, a weight of about 700 g (1.5 lbs) and a wingspan of about 105 cm (42 in). Adults have a brownish head, a reddish chest and have a pale belly with reddish bars. Their tail, which is quite long by Buteo standards, is marked with narrow white bars. The red "shoulder" is visible when the bird is perched. Their upper parts are dark with pale spots; they have long yellow legs. Western birds may appear more red; Florida birds are generally paler. The wings of adults are heavily barred on the upper side, less so on the underside. Juvenile Red-shouldered Hawks are most likely to be confused with juvenile Broad-winged Hawks, but can be distinguished by their long tail, crescent-like markings on the wings and their more flapping, Accipiter-like flight style.
Usually, while in forested areas, these birds wait on a perch and swoop down on prey. When in clearings, they sometimes fly low in order to surprise prey. Small mammals are typically the most important prey, with voles, mice and chipmunks locally favored. Other prey can include amphibians, reptiles (especially small snakes), small birds and large insects. During winters, they sometimes habituate to preying on more common birds, such as House Sparrows, Mourning Doves and European Starlings, at bird feeders.
Their breeding habitats are deciduous and mixed wooded areas, often near water. It is while establishing territories that the distinctive, screaming kee-aah call (usually repeated 3 to 4 times) of this bird are heard. The breeding pair build a stick nest in a major fork of a large tree. The clutch size is typically 3 to 4 eggs. The blotchy-marked eggs are typically 54.5 x 43 mm (2.1 x 1.7 in). The incubation period can range from 28 to 33 days. The hatchlings, 35 g (1.2 oz) at first, are brooded for up to 40 days. The young leave the nest at about six weeks of age, but remain dependent on the parents until they are 17 to 19 weeks old. Predators of eggs and birds of all ages include Great Horned Owls, Red-tailed Hawks, Peregrine Falcons, raccoons, martens, and fishers (adults are vulnerable to the mammals only while nesting). Interestingly, Red-shouldered Hawks sometimes collaborate and peaceably co-exist with American Crows (usually an enemy to all other birds because of their egg-hunting habits) in order to mob Great Horned Owls and Red-tailed Hawks.
These birds are permanent residents throughout most of their range; northern birds do migrate however, wintering mostly in central Mexico. The major modern threat to these birds is deforestation, which has eliminated these birds as breeders in some areas.
