Convex mirror on red clapboard facade, Newport, RI

That's it. Just took a picture through the peephole in the door.

Desfile de modas de alumnos y egresados de la carrera de diseño de moda de Arte A.C., realizado el 26 de mayo de 2009 en el Centro Convex de Monterrey, México.

Durante el evento los diseñadores presentaron sus colecciones y se entregaron premios al mejor empleo de textiles y materiales y mejor diseño visual.

If I tried hard enough, I could see the airport from my window. I wonder where that plane is going.

 

This looks like thirty-eight times better on black.

today was our son's birthday party, we arranged a fire engine as a surprise through 'hire a fire engine'. yes, both we both enjoyed our first ride in a fire engine along with C's friends. the truck is a 1969 Ford D600, with only 20,000 miles on the clock. if you're interested, you can find more details on www.hireafireengine.co.nz or 0800 fire engine.

A convex spokeshave model no 51 from the Stanley Sweetheart era. This spoekshave has been well used and features almost no japanning, but still has the original SW cutter. Some pitting on the cutter, but still in good working order.

As you move the object, the image moves. Do not assume that the image is at the focal length- this is only true for images that are really far away from a lens (at infinity, photographers would call it.)

 

Making sure you understand the patterns on what happens to the image as you move the object is pretty important

An object really far away from a converging lens will produce an image at the focal point of the lens. Mr Dowd's 1956 Soviet Ukrainian Fed 2b camera with its fully manual workings makes it pretty easy to see the physics that's going on. The image on the upper right and the diagram below show the camera set to infinity. Close examination of the barrel of the lens shows that infinity for this lens (an Industar 26m) is anything beyond 20m. The image created is at the focal point of the lens, which is set to be where the film at the back is. A modern camera would have a CCD here.

 

When a lens is focused to a distance other than infinity, the image forms at a place other than the focal point. This is accomplished by moving the lens in or out, so that the film or CCD is at the appropriate image distance. You can see that the image on the left has the camera focused to 1m, and the barrel is extended, moving the lens away from the film. This Industar 26m lens allows clear images to be made at distances from 1m to infinity. Other lenses with different geometries could allow closer images to be made.

The trimmed seam allowance produced a nice clean rounded edge on the turned seam.

Tortue de Floride

Trachemys scripta elegans

 

Répartition

Cette sous-espèce se rencontre originellement dans l'est des États-Unis entre les Appalaches et les Rocheuses et dans le nord-est du Mexique. Elle a été introduite dans de nombreux pays.

Il s'agit d'une tortue aquatique vivant normalement dans les lacs, étangs et marécages

Description[modifier | modifier le code]

 

La Tortue de Floride a une longévité évaluée à environ 50 ans.

 

Lorsque la Trachemys scripta elegans est juvénile, sa nourriture se compose de 90 % de poisson et 10 % de végétaux.

 

Cette tortue n'est plus en vente libre en France car elle est considérée comme invasive. Il faut donc être titulaire du certificat de capacité et d'une autorisation d'ouverture d'établissement pour la posséder.

 

Dimorphisme sexuel

 

Reconnaître une tortue de Floride femelle en 3 points.

On peut différencier le mâle de la femelle par quelques caractéristiques :

1.La taille et la forme des griffes : en effet, les griffes du mâle sont courbées et longues tandis que les griffes de la femelle sont droites et plus courtes.

2.La forme du plastron : la forme du plastron du mâle est plutôt concave et convexe chez la femelle.

3.La taille de la queue : Le mâle a une queue plus grande que la femelle. L'ouverture cloacale de la queue est plus éloignée de sa base chez les mâles.

4.Généralement, les femelles sont plus grandes que les mâles.

Noter que, comme pour les autres espèces de tortue, il est très difficile de déterminer le sexe des jeunes.

 

La reproduction[modifier | modifier le code]

 

L'accouplement se passe peu de temps après que la tortue a fini d'hiberner. Il se traduit par une attitude assez agressive du mâle avant de vraiment passer à l'action. Lors de la parade, le mâle se met devant la femelle, tend ses bras parallèlement à sa tête, et, paumes à l'extérieur, fait vibrer ses longues griffes qui effleurent la tête de la désirée. Il peut mordre la femelle. Cette attitude est parfois observée, sans accouplement : il s'agit dans ce cas d'une pose d'intimidation (défense du territoire principalement). Il faut alors observer attentivement les animaux et les séparer pour de bon dans 2 bacs différents si les bagarres sont trop graves.

 

Si l'accouplement a bien été effectué, la femelle peut effectuer plusieurs pontes par an (2 en moyenne). Chacune des pontes comprend entre 5 et 20 œufs. La durée d'incubation varie entre 60 et 80 jours. Il est important de maintenir un bon taux d'hygrométrie ainsi qu'une température constante pendant toute la durée de l'incubation

 

I've never seen this before, though I can see what's happened. When the snow was really deep, someone walked through it, compressing it under their footprints. Now the top layer has blown off in the high winds, leaving the more compressed snow behind. It was very strange! See the next photo for lots of these.
