Ah the good life. Its easy to imagine what it was like when the original owners lived here. Perched 450 feet above the Spokane River valley, Royal Newton Riblet established this now historic Spokane landmark in 1924. An inventor and mechanical innovator, Riblet not only developed a variety of patented devices, including a square-wheel tractor, pattern sprinkler system and mechanical parking garage, he was also the chief engineer and designer of his beautiful home and estate. At the time of its construction in the early 1920s, it was among the most “wired” homes in the nation.

Airbus A-350-941
(special "CleanTechFlyer" c/s)
leased from Goshawk Aviation.
Munich (MUC) - Vancouver (YVR),
LH476
Trip time 9:48
Altitude approx. 6500ft,
Flying over, Vancouver, British Columbia, Canada,
Approaching, Vancouver International airport,
The Airbus A350 is the cleanest and most modern of them all. Fuel consumption has been reduced to around 2.5 liters of kerosene per passenger per 100 km flown, which is about 30% less than its predecessor models.
The percentage has an immediate positive impact on carbon dioxide emissions. In addition, the advanced engines, ultramodern materials, and an aerodynamic design produce a noise footprint up to 50% smaller than that of similar aircraft types. Thus, an all-white Airbus A350 dedicated to drawing attention to the German carrier's sustainability initiatives.
One exciting technology includes sharkskin technology, as Lufthansa Technik partnered with BASF to develop an adhesive bionic film that replicates the skin of sharks, given how sharks are efficient in drag reduction. Known as AeroSHARK, the bionic film has microscopic properties that consist of eponymous riblets. Once the AeroSHARK is applied to an aircraft, the riblets achieve efficiency gains by reducing skin friction and drag, similar to their natural counterparts. They can also improve lift if attached to wings.

measurement to film plane approx. 4", 101mm.
update: rather than fight trying to guess on exposure time, with lauren.rabbit's recommendation and with Michael Riblet's help too, I ordered a set of 12 pre-drilled pinhole plates and a chart for focal lenth/diameter of pinhole and exposure times.
I'm burning through too much film; wasteful me.

Sky Sharks, Meet Sharknado! Tech Innovation From Nikon! - IMRAN™
This news item caught my attention today. Even though I had not (and would not) see the movies Sky Sharks or Sharknado, the movie references came to mind immediately.
"Nikon unveils sharkskin-inspired riblet technology for aviation and power" ( lnkd.in/ebTXK9qW ). It basically is a biomimetic technology which mimics the amazing surface structure of shark skin. Nikon’s proprietary laser processing creates riblets which are artificial microstructures which resemble the fine scales on a shark’s skin. The materials have many applications from aviation to power generation.

I wanted something different for dinner than the usual fast food fare, and I had some time I was trying to kill, so I chose Applebee's. I ended up getting the Caprese Mozzarella Chicken, which wasn't bad, but not something I would order again. I'm STILL mad they got rid of the riblets...
(9/2018: So apparently the riblets are a thing again. Too bad they weren't when I was here. I think this might've been the last time I've been to any Applebee's)

I enjoy cooking and baking so I don't mind being forced to eat my own food and no one else minds either as they have enjoyed my signature brand of "use it up so it doesn't go bad first" cooking. My presentation may not be great but the taste is more important anyway.
So clockwise we have...
1- me using up sugar packets I've been hoarding for years. I used all my Wendy's sugar up finally. haha.
2,3, & 4 - me filling puffed pastry shells with the last of the honey crisp apples I stewed down and made into apple puffs complete with a brown butter glaze.
5- veal breast riblet (only meat left at the store when we got it) slow cooked in white wine (last bottle) and garlic cloves (last bunch)
6&7- Bead pudding using the slightly stale challah raisin bread with a bananas foster rum glaze using the last two ripe bananas from this week.
8- carrot cupcakes (using the last of the fresh carrots) with a brown butter cream cheese frosting. Some with pecans some without.
9- Baked pasta using up the last of the sausage, fontina cheese and mozzarella cheese.
10- Lemon pancakes using up the last fresh lemon.
11-egg omelet using the last bit of salsa and cheddar cheese.
12 - beer battered shrimp using some more of the leftover corona beer.
13- banana bread using up two ripe bananas from two weeks ago.
14- and in the center. What I ate for my birthday which was a bacon chili cheese burger using up all the bacon .
P.S. We restocked the fridge this week for the next few weeks and we start all over again by making sure nothing goes to waste.
Riblet attended the Tucson Pet Expo this past Saturday. There he was able to witness sister Rihanna get adopted.
The only two from the litter left available for adoption are Riblet and sister Ramona.
This attire was a little taut on Riblet, as the horns wouldn't fit over his dome.
Riblet is still available for adoption. Most of his brothers and sisters are Black Labs.

Remarkably, Riblet and Reba are very fair furred, while the other siblings closely resemble Black Labrador mixes.
West 50th Street | Broadway 26/04/2015 18h13
After a journey of more than 5,900 kilometers and a discovery walk in Theatre District in midtown Manhattan it was time for a bite. Applebee's on the corner of Broadway and 50th Avenue was a good option for this first night.
Applebee's
Applebee’s International, Inc., is an American company which develops, franchises, and operates the Applebee's Neighborhood Grill and Bar restaurant chain. As of December 2011, there were 2,019 restaurants operating system-wide in the United States, one U.S. territory (Puerto Rico) and 15 other countries. The company is headquartered in Kansas City, Missouri after moving from Lenexa, Kansas in September 2011.
The Applebee's concept focuses on casual dining, with mainstream American dishes such as salads, shrimp, chicken, pasta, and "riblets" (which is considered Applebee's signature dish). All Applebee's restaurants feature a bar area and serve alcoholic beverages (except where prohibited by law).
On November 29, 2007, IHOP (now DineEquity) announced that it had completed a $2.1 billion purchase of the Applebee's chain.

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 .

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
