Tower Transit utilise all three of the newer generation of Volvo hybrids but this is one of a few routes to get these smiley faced units with this operator.
The 212 runs close to the Overground rail line but serves the housing areas just before it gets to Walthamstow. These buses look pretty good; well maintained and well used.

At last! A steam tour comes to town after months of silence, today in the form of flagship British Railways Standard Class 7, 70000 'Britannia', hauling the 'Torbay Express' from Bristol Temple Meads to Kingswear and return. Here the train is seen swinging around the corner at Eastcliff just outside Teignmouth station, working the outbound service.
One of the last and most powerful steam locomotives ever built, the British Rail Standard Class 7 was BR's top express locomotive, and could have been utilised far better in its short lifespan, but ended up only serving the railways for 15 years, a blink of an eye compared to other mainline Pacifics of the time that had operated under the pre-nationalisation companies.
Designed by Robert Riddles, who had previously coined the design for the War Department Austerity 2-10-0 and 2-8-0 freight locomotives, the BR Standard Class 7's were conceived of as a result of the 1948 locomotive exchanges, which were done to test the best and worst aspects of locomotive design within the Big Four railway companies that had existed before nationalisation. The research gained from operating the best designs of the GWR, LMS, LNER and Southern railways on different areas of the British Railways network paved the way for several new classes of standardised locomotives to be constructed, largely to replace many of the ageing Victorian era engines that even in the late 1940's continued to ply their merry trade.
The first design requested by the Railway Executive was for a new express passenger Pacific locomotive, designed specifically to reduce maintenance and using the latest available innovations in steam technology from home and abroad. Various labour-saving devices were utilised to produce a simple, standard and effective design, able to produce equivalent power to some of the Pacifics that were still available as legacies of the Big Four.
The basic design of the Standard 7's can be traced to LMS construction practices, largely owed to Riddles' previous career with that company, but complimented this with the boiler and trailing wheel design of the Southern Railway's Merchant Navy Pacifics so as to follow the best design practice. The firebox was also similar in having a rocking grate, which allowed the fire to be rebuilt without stopping the locomotive, removing both ash and clinker on the move. A self-cleaning smokebox was used, which enabled ash to flow into the atmosphere, reducing the workload of the engine cleaner at the end of a working day. A single chimney was placed on top of the smokebox, which was unusual for a Pacific type of locomotive.
The Standard 7's were fitted with 6 ft 2 in driving wheels, allowing these engines greater capacity for use in mixed-traffic working, which made them available for both sustained fast running with heavy passenger trains, yet small enough to allow them to undertake more mundane tasks such as freight haulage.
55 of these engines were constructed between 1951 and 1954, with 70000 'Britannia' being the first and flagship of the fleet, with residual locomotives of the class being dubbed 'Britannia-Class'. Three batches were constructed at Crewe Works, before the publication of the 1955 Modernisation Plan.
Britannia was built at Crewe, completed on 2 January 1951. She was the first British Railways standard locomotive to be built and the first of 55 locomotives of the Britannia class. The locomotive was named at a ceremony at Marylebone Station by the then Minister for Transport Alfred Barnes on 30 January 1951. The BR Locomotive Naming Committee were determined not to use names already in use on other locomotives. They tried to observe this by not selecting the name Britannia for use on 70000 because it was already in use on one of the ex-LMS Jubilee Class locomotives, but Robert Riddles overruled them and the Jubilee had to be renamed.
The Britannias took their names from great Britons, former Star Class locomotives, and Scottish firths, although one locomotive, 70047, was never named. The success of these first Standard Pacifics gave birth to two other Pacific classes over the BR years, including the unique BR Standard Class 8, number 71000 'Duke of Gloucester', which was built in 1954 to replace the destroyed Princess Royal Class locomotive number 46202 Princess Anne, lost in the Harrow and Wealdstone rail disaster of 1952, and the fleet of 10 BR Standard Class 6 'Clan' Pacifics that were employed on services in the west of Scotland, but failed to gain a stellar reputation due to their employment on timetables for the more powerful Standard 7's they couldn't keep up to.
The class gained a warm response from locomotive crews across all British Railway Regions, with especially glowing reports from those operating them from Stratford depot on the Eastern Region, where its lower weight and high power transformed motive power over the restricted East Anglian lines. However, negative feedback was received from various operating departments, most notably on the Western Region. The criticism was primarily out of partisan preference for GWR-designed locomotive stock among Western Region staff; in particular, the class was 'left-hand drive' in contrast to 'right-hand drive' GWR locomotive and signalling practice, a factor in the Milton rail crash of 1955.
For this reason, the Western Region locomotive depots at Old Oak Common and Plymouth Laira declared that the class was surplus to requirements. However Cardiff Canton depot displayed its liking for the class (despite being part of the former GWR empire) and managed to obtain good results on South Wales passenger traffic.
The Midland Region also had favourable reports, but a marked consistency in losing time on the longer runs between Holyhead and Euston was recorded, although all complaints were down to the individual techniques of the operating crews. This was compounded by the irregular allocation of the class to depots all over the network, meaning that few crews ever had a great deal of experience in driving them. The Southern Region also had an allocation of seven in May 1953, when all Merchant Navy Class locomotives were temporarily withdrawn for inspection after 35020 "Bibby Line" sheared a crank axle on the central driving wheel.
Repairs to the class were undertaken at Crewe, Swindon and Doncaster Works until the financial constraints of the British Railways Modernisation Plan in terms of expenditure on steam began to preclude the regular overhaul of locomotives. During the mid-1960s overhauls were carried out exclusively at Crewe Works.
Britannia was initially based at Stratford in order to work East Anglian expresses to Norwich and Great Yarmouth, but was also particularly associated with the Hook Continental boat train to Harwich. Subsequently, the loco was based at Norwich Thorpe in January and March 1959 before spending the remainder of her career on the London Midland Region based at Willesden, Crewe North, Crewe South and finally Newton Heath.
The locomotive also had the distinction of hauling the funeral train for King George VI from King's Lynn, Norfolk to London following his death in February 1952 at Sandringham House, Norfolk. For this task, Britannia had her cab roof painted white, as was the custom with royal locomotives. Britannia has also worn the white roof in preservation.
However, as the locomotives entered the 1960's, the modernisation plan continued to gather pace, and diesel locomotives started to replace steam on most parts of the network. Very soon the Standard 7's placement on Top-Line expresses were demoted to the on-again-off-again work of freight and parcels, and cosmetic maintenance was reduced as their final years loomed. The lavish BR Brunswick Green soon faded to grey, and in some cases BR Lined Black was adopted for ease.
The first locomotive to be withdrawn from service was number 70007 Coeur-de-Lion in 1965, and the entire class was gradually transferred to Carlisle Kingmoor and Glasgow Polmadie depots. Britannia was withdrawn in May 1966, after 15 years of service.
A succession of bulk withdrawals began in 1967, culminating in the very last steam operation in British Railways service on August 11th, 1968, where Standard 7 number 70013 Oliver Cromwell, was chosen to assist in hauling the Fifteen Guinea Special, the last steam hauled British Railways passenger service from Liverpool to Carlisle via the S&C. 70013 was chosen as it was the last the last BR-owned steam locomotive to undergo routine heavy overhaul at Crewe Works, being out-shopped after a special ceremony in February 1967. The engine hauled the Manchester to Carlisle leg of the service via the Settle and Carlisle line, with LMS Class 5 45110, and LMS Stanier Class 5 locomotives, 44781 and 44871 double-heading the return working back to Manchester.
Upon withdrawal, 70000 was initially planned for preservation with the National Railway Museum due to it's cultural significance, but because of its prototypical nature, 70013 was instead chosen and bought up for preservation. 70000 would later be preserved by Britannia Locomotive Company Ltd.
After moving from one home to another, the engine wound up on the Severn Valley Railway, where she remained for a number of years in operational but non-mainline condition. With the society wishing to make more use of the locomotive, she was moved to the European gauge Nene Valley Railway in Peterborough, where she was also fitted with an air-brake compressor. Britannia made her return to the main line on 27 July 1991, successfully working enthusiast trips until 1997.
With an expired mainline boiler certificate, due to the high cost of refurbishment, the locomotive was sold to Pete Waterman in 2000. Stored at Waterman's workshops at the Crewe Heritage Centre, after initial assessment the amount of work resulted in Waterman selling her to Jeremy Hosking. The locomotive underwent restoration at Crewe which involved a newly refurbished cab, a new smoke box and major work on the boiler; replacement steel sides, new crown stays, new front section barrel section, new steel and copper tubeplate, repairs and patches to door plate and major work to copper firebox.
Transferred to the Royal Scot Locomotive and General Trust, the locomotive was returned to main line operational condition in 2011, initially out shopped in its prototype black British Railways livery. After a running-in period, in 2012 the locomotive was repainted in British Railways Brunswick Green, but with an early BR crest. On 24 January 2012, the loco hauled the Royal Train with Prince Charles on board to Wakefield Kirkgate, where he rededicated the locomotive. For the trip the loco again had a painted white cab roof, removed after the engine's appearance at the West Somerset Railway's Spring Gala.

Plante Médicinale avec un effet antiseptique, utilisée principalement lors de problèmes oculaires comme la conjonctivite,
Le Polonnaruwa Vatadage est une ancienne structure remontant au royaume de Polonnaruwa du Sri Lanka . On pense qu'il a été construit pendant le règne de Parakramabahu I pour tenir la relique de la dent du Bouddha ou pendant le règne de Nissanka Malla de Polonnaruwa pour tenir le bol d'aumône utilisé par le Bouddha. Ces deux reliques vénérées auraient donné à la structure une grande importance et une grande importance à l'époque. Situé dans l’ancienne ville de Polonnaruwa , c’est le meilleur exemple de vatadage le mieux conservé dans le pays et a été décrit comme le "développement ultime" de ce type d'architecture. Abandonnés depuis plusieurs siècles, les travaux d’excavation du Polonnaruwa Vatadage ont débuté en 1903.
Construit pour la protection d'un petit stupa , la structure a deux plates-formes en pierre décorées avec des sculptures en pierre élaborées. La plate-forme inférieure est accessible par une seule entrée face au nord, tandis que la seconde plate-forme est accessible par quatre portes donnant sur les quatre points cardinaux. La plate-forme supérieure, entourée d'un mur de briques, contient le stupa. Quatre statues de Bouddha sont placées autour, chacune faisant face à l'une des entrées. Trois rangées concentriques de colonnes de pierre avaient également été placées ici, probablement pour supporter un toit en bois. La structure entière est décorée de sculptures en pierre. Certaines des sculptures du Polonnaruwa Vatadage, telles que ses sandakada pahanas, sont considérés comme les meilleurs exemples de telles caractéristiques architecturales. Bien que certains archéologues aient suggéré qu'il avait aussi un toit en bois, cette théorie est contestée par d'autres.

___________________________________
The Polonnaruwa Vatadage is an ancient structure dating back to the Kingdom of Polonnaruwa of Sri Lanka. It is believed to have been built during the reign of Parakramabahu I to hold the Relic of the tooth of the Buddha or during the reign of Nissanka Malla of Polonnaruwa to hold the alms bowl used by the Buddha. Both these venerated relics would have given the structure a great significance and importance at the time. Located within the ancient city of Polonnaruwa, it is the best preserved example of a vatadage in the country, and has been described as the "ultimate development" of this type of architecture. Abandoned for several centuries, excavation work at the Polonnaruwa Vatadage began in 1903.
Built for the protection of a small stupa, the structure has two stone platforms decorated with elaborate stone carvings. The lower platform is entered through a single entrance facing the north, while the second platform can be accessed through four doorways facing the four cardinal points. The upper platform, surrounded by a brick wall, contains the stupa. Four Buddha statues are seated around it, each facing one of the entrances. Three concentric rows of stone columns had also been positioned here, presumably to support a wooden roof. The entire structure is decorated with stone carvings. Some of the carvings at the Polonnaruwa Vatadage, such as its sandakada pahanas, are considered to be the best examples of such architectural features. Although some archaeologists have suggested that it also had a wooden roof, this theory is disputed by others.

« Le miroir, utilisé ici tel un language plastique, peut être source d'illusions mais aussi de prise de conscience. Il permet au blockhaus d'utiliser la nature pour se faire oublier, se camoufler. Mais en disparaissant, il révèle.
Cette seconde peau le fait passer de l'ombre à la lumière.
En créant un espace d'illusion, le miroir dénonce comme plus illusoire encore l'espace réel et l'aveuglement dans lequel nous vivons.
Ce monument solaire, ce « contre espace » permet de laisser entrer l'imaginaire dans le béton.
Il démontre la possibilité d'une victoire de l'imagination et de la création sur la destruction. »

« The mirror, used here like a plastic language, can be sourced of illusions but also awareness.
He allows the bunker to use the nature to be forgotten, disguise. But by disappearing, it reveals.
This second skin makes it pass from the shadow to the light.
By creating a space of illusion, the mirror denonces as more illusive still the real space and the blindness in which we live.

The Dachs CEV isa development of the Leopard tank in Voightländische service. It utilises the same basic chassis, but with modifications to allow for more room inside. Again, the “Pullover” package is installed, with ERA blocks added to the upper glacis, and the side skirts were lined with rubber layers, just like on the Leopard 1b.
More of an APC than a real CEV, the Dachs is a combat engineer section carrier, capable of carrying 8 operators, of which 7 can deploy via the large roof hatch on the rear, or the two other smaller hatches. It is armed with a variety of machine guns, ranging from a manually-controlled 7.62mm to a remotely-controlled 12.7mm OWS. Smoke grenade launchers are also present on the four corners.
For mine-clearing duties, the Dachs can be equipped with mine rollers and the Carpet mine-clearing system, consisting of 18 rockets that can be fired separately or all at once. These contain a fuel-air explosive warhead which spreads a cloud of fuel fumes that are then detonated. The overpressure from the explosion destroys most mines. There is also electronic equipment inside the vehicle for detonating roadside bombs or jamming detonation signals.
Other options include a dozer blade, and an A-frame crane, capable of lifting 35 tons when the spades are deployed. The winch is installed where the large hatch was, and has a 45 tons direct pull capacity.

On m'a acheté cet exemplaire des Fleurs du mal lorsque j'étais au collège, j'ai utilisé le même au lycée et plus tard lorsque j'avais besoin de Baudelaire. Aujourd’hui je peux assez rapidement retrouver les poèmes que je connais dans cet ouvrage, et quand bien même on m'a offert une édition bien plus luxueuse récemment, c'est toujours vers l'ancien que je me tourne quand le besoin se fait sentir.

I was given this copy of Les Fleurs du Mal when I was in middle school, I used the same one in high school, and later on, whenever I needed Baudelaire. Today I can quite quickly find the poems I know in this book, and even though I was recently given a much more luxurious edition, I still turn to the old one when the need arises.

Cet ancien monastère de chanoines augustins, fondé en 1106, est si-tué dans le creux d'un vallon boisé où coule la Seine, dont la source se situe à quelques kilomètres plus au Sud. Le lieu ne fut pas choisi par hasard puisqu'il répondait à tous les critères nécessaires à la vie autarcique, avec la présence d'eau, de bois, de pierre et de vastes terrains à défricher.
Même si l'abbaye d'Oigny n'a pas créé d'ordre monastique au sens propre, son coutumier servira néanmoins de base à la création de l'ordre des Prémontrés.
Sa période de prospérité s'étend du 12ème siècle au 18ème, sous le régime de commende. Lors de la Révolution, ses bâtiments et pos-sessions sont saisis et vendus aux familles qui exploitent les terres attenantes. Une partie de l'abbaye est ainsi utilisée en exploitation agricole tandis que l'autre est transformée en demeure bourgeoise.
Acquise en 1840 par la famille Terrillon, l'abbaye prend alors l'aspect qu'on lui connait actuellement, c'est-à-dire dépourvue de son église -détruite par un incendie- et de son cloître -démoli lors de travaux de rénovation- mais conservant les autres bâtiments du 17ème siè-cle, dans leur forme extérieure tout du moins.
Aujourd'hui, les extérieurs et intérieurs de l'abbaye -pourtant inscrite à l'inventaire supplémentaire des monuments historiques- restent des espaces d'habitations privées qui, malheureusement, ne se visi-tent qu'exceptionnellement.

Le basilic est une plante herbacée utilisée en tant qu'aromate en cuisine. Sa saveur parfumée est caractéristique des plats italiens mais il est également très utilisé dans les pays asiatiques notamment en Thaïlande.
Plante de 20 à 60 cm de haut, le basilic possède des feuilles ovales-lancéolées, atteignant 2 à 3 cm, de couleur verte pâle à verte foncée, parfois pourpre violet. Il peut cependant facilement atteindre plus d'un mètre de longueur lorsqu'il est conservé plusieurs années.

Mark travaille dans le sas du module japonais Kibo, utilisé entre autre pour déployer des nano-satellites depuis la Station. La station spatiale internationale est aussi… un centre de lancement de vaisseaux spatiaux ! OK uniquement pour des nano-satellites (qu’on appelle aussi souvent cubesats, d’une taille entre un Rubik’s cube et une boîte à chaussures, mais remplis de technologie). Le processus est assez sympa : les astronautes installent les cubesats dans un lanceur (à ressort !), lui-même monté sur une table coulissante qui fait partie intégrante du sas du module-laboratoire Japonais. Sur ces photos vous voyez Mark et Aki préparer des nanosats et le sas. Pour les lancements, on ferme l’écoutille de l’intérieur, puis l’écoutille externe s’ouvre et le déployeur glisse vers l’extérieur. Le bras robotique récupère le déployeur, il vise (il ne s’agirait pas que les cubesats deviennent des projectiles dangereux pour nous après une orbite ou deux) et finalement il propulse les cubesats dans l’espace ! Aki était ce jour-là chargé de filmer la scène depuis notre poste d’observation habituel, la Cupola. Ces satellites sont formés à partir de cubes de 10 cm de côté (pour la compatibilité avec le lanceur) mais ils sont modulables, c’est à dire qu’on peut combiner 2, 6 ou pourquoi pas 12 unités pour en former des un peu plus volumineux et complexes – tout de même très petits par rapport à un satellite conventionnel. Mais grâce à la miniaturisation des technologies, leurs capacités sont impressionnantes. Les deux derniers nanosats lancés depuis l’ISS ont réalisé pour l’un des essais d’aérodynamisme en orbite basse pour l’université de Manchester, et pour l’autre surveillé des feux de forêt, pour la Robertsville Middle School. Et ce n’est pas le moins important : cette approche utilise l’ISS pour rendre l’espace accessible aux universités, aux petites entreprises ou même aux nations qui n’ont pas traditionnellement les moyens d’envoyer leur technologie en orbite !
Mark working with the airlock in Japan's Kibo module, used amongst other things to deploy miniature satellites from the Space Station! The International Space Station is also a spacecraft launch centre! Small nano-sats (also called cubesats because of their shape, you would have guessed) can be placed with a launching device inside this mini-airlock in JAXA's Kibo lab. Mark and Aki prepared the satellites and worked on the airlock. We close the hatch on the inside, the outer hatch opens and the a launcher slides out. The Japanese robotic arm collects the launcher, aims and springs shoot the cubesats off into space! Aki took videos and pictures from Cupola of the new satellites on their way. They are only variations of cubes 10x10x10 cm so they are not easy to spot in the last picture, but with technology miniaturisation even these little satellites can do very interesting things! Two satellites were launched, one led by the University of Manchester, and the other by Robertsville Middle School, the first will test aerodynamics in low Earth orbit, and the former monitor forest fires. I love how such a device can allow access to space to some smaller companies or universities or countries that can’t traditionally afford the costs of spaceflight.

Ces satellites sont formés à partir de cubes de 10 cm de côté (pour la compatibilité avec le lanceur) mais ils sont modulables, c’est à dire qu’on peut combiner 2, 6 ou pourquoi pas 12 unités pour en former des un peu plus volumineux et complexes – tout de même très petits par rapport à un satellite conventionnel. Mais grâce à la miniaturisation des technologies, leurs capacités sont impressionnantes. Les deux derniers nanosats lancés depuis l’ISS ont réalisé pour l’un des essais d’aérodynamisme en orbite basse pour l’université de Manchester, et pour l’autre surveillé des feux de forêt, pour la Robertsville Middle School. Et ce n’est pas le moins important : cette approche utilise l’ISS pour rendre l’espace accessible aux universités, aux petites entreprises ou même aux nations qui n’ont pas traditionnellement les moyens d’envoyer leur technologie en orbite !
Mark working with the airlock in Japan's Kibo module, used amongst other things to deploy miniature satellites from the Space Station! The International Space Station is also a spacecraft launch centre! Small nano-sats (also called cubesats because of their shape, you would have guessed) can be placed with a launching device inside this mini-airlock in JAXA's Kibo lab. Mark and Aki prepared the satellites and worked on the airlock. We close the hatch on the inside, the outer hatch opens and the a launcher slides out. The Japanese robotic arm collects the launcher, aims and springs shoot the cubesats off into space! Aki took videos and pictures from Cupola of the new satellites on their way. They are only variations of cubes 10x10x10 cm so they are not easy to spot in the last picture, but with technology miniaturisation even these little satellites can do very interesting things! Two satellites were launched, one led by the University of Manchester, and the other by Robertsville Middle School, the first will test aerodynamics in low Earth orbit, and the former monitor forest fires. I love how such a device can allow access to space to some smaller companies or universities or countries that can’t traditionally afford the costs of spaceflight.
