Year 3, Day 26
St Clement, Ipswich, Suffolk
St Clement, the patron saint of seafarers, was a perfect choice for this, the largest of the dockland churches. The parish has been inextricably linked with seafarers for over a thousand years.
Ipswich town centre has twelve medieval churches, and there are others out in the suburbs, but as with any industrial town, the changing population patterns of the last half a century have meant that some of the parishes ended up with no resident population. St Clement was always the largest, poorest and most populous of Ipswich's parishes. But 20th Century slum clearances and the taking over of the waterfront by industry led to the population's decline, and then of course the industry itself began to disappear.
By the 1970s, six of the town centre churches had been declared redundant, and it was a long, slow grind before reuses were found for many of them. At the start of the 21st Century, five of them still stood abandoned and, in some cases, near derelict, because the presumed 'wholly commercial' reuses had not emerged. Gradually, the optimism and public finance of the first decade of the century drew four of these into community reuses, until at last only St Clement remained.
And yet, St Clement has the finest setting of all the dockland churches, despite the one-way system passing within ten metres of its north side. The road was built over that part of the churchyard which adjoined the ironworks, which still survives across the road. Seen from this road, the handsome church is stately among its great trees. The clutter of small buildings that have surrounded it for hundreds of years have been cleared away, opening up a fine view from the west.
Until the 1960s the graveyard was almost completely enclosed, accessible only by the footpath which still survives coming from Grimwade Street beside the former parish hall. Approached along this path, the church is a secretive giant, rising shyly among the overgrown trees. The church itself is a fine example of fairly late perpendicular church-building, with a grand tower and as magnificent a clerestory as any of the Ipswich churches. The chancel was the work of that ubiquitous Ipswich architect Frederick Barnes.
For a long time, the view from the outside has been all you are able to see. The church was declared redundant in the early 1970s, and has been closed ever since, the largest of all Ipswich's redundant churches. In the 1980s, it was the victim of a great deal of vandalism because of its position, relatively isolated from mainstream town life. The sheltered south side of the churchyard in particular became littered with the kind of things that you wouldn't want your children to pick up. The church itself became a prop-store for the Wolsey Theatre, and it was surreal indeed to walk among the fibre-glass cannons, cardboard grandfather clocks and Scottish warrior outfits that were stacked high in the nave and aisles.
The church was left pretty much as it was on the day it closed, as if the churchwardens had put away the hymn books and slipped out after that final Evensong. However, in 1996 a disastrous fire swept though St Clement, completely destroying the 1880s roof. This was soon rebuilt, and, combined with a clear-up for the churchyard came landscaping and a memorial to a famous mariner son of the parish, Thomas Slade.
Suffolk College took on the lease on the building, but gave notice in 2001 that they would not be renewing it. The late John Blatchly, of the Ipswich Historic Churches Trust, told me at the time that there was a potential commercial user interested in taking it on in the future, but I thought it unlikely that this would happen. Visiting it at the time, I found this big church disarmingly bare, with a slight air of dereliction.
In fact, the former congregation here kept a weather eye on it, still opening it up on Historic Churches Bike Ride day, which was more than could be said for some of the other redundant Ipswich churches. The redecoration and rebuilding of the roof after the fire had made it sound, and it was obvious that it wouldn't be too difficult to convert the building for an appropriate use - as a concert space, perhaps, or even for one of the new evangelical churches. I wondered if even the Catholic Church might take a look, since they don't possess a large worship space among their five Ipswich churches, which are often overcrowded.
Coming back here in 2005, I was pleased to discover that the interior had been spruced up. The royal arms, which fortunately survived the fire, are probably the best example of Ipswich's familiar Charles II sets. These are different to the others in that they are carved and gilded rather than being painted on boards or canvas. The wall beside them above the tower arch is resplendent with 19th Century scroll work. The font, reset by the Victorians in the westward extension of the south aisle, is a typical East Anglian rural 15th century font, with angels on the bowl and lions and wild men around the stem, giving a rustic air to this corner.
The church suffered considerable blast damage during the Second World War, only four of the stained glass windows surviving. Remarkably, there is still a small former bomb site to the south-west of the church beside the Lord Nelson pub. After the war, the damaged east window was replaced by a striking depiction of the Ascension by Abbott & Co of Lancaster, a memorial to a local doctor killed in the Second World War. The glass on the south side of the chancel depicting the Nativity and the Annunciation is by Ward & Hughes, and is good for the workshop. That of the Presentation in the Temple at the east end of the south aisle is by Powell Brothers of Leeds, also good. Ward & Hughes' Transfiguration in the north aisle is perhaps less good, and the Good Shepherd window by Ide & Sons of London in the south aisle is rather spoilt by the cartoony central figure of Christ.
St Clement is remarkable for the quantity of its memorials, and the quality of some of them. The best is probably that to John Ward, rector here throughout the Commonwealth period and beyond the Restoration. It was reset in the chancel along with a number of the others by the Victorians, and John Blatchly credited it to the Danish sculptor Caius Cibber, who was a great favourite of the English court.
There was an enthusiasm here in the early part of the 20th Century for small memorial plaques, mostly produced by the Scott & Co Foundry of Ipswich, commemorating those lost at sea. This extended into the first years of the Great War, after which the sheer magnitude of losses seems to have put a stop to the project. The bleak reredos serves as a parish war memorial, the names of the lost on a tablet on the west wall.
All too easily, this church could have been lost to dereliction and vandalism. As it was, St Clement stood still while Ipswich changed around it. The 1960s demolition of virtually all of the housing in the parish that had led to its redundancy was effectively redressed by the massive Waterfront regeneration, the almost complete rebuilding of Ipswich's wet dock area. St Clement now has many new neighbours, and most of them are residential. St Clement sat and waited, as patiently as it had done for the previous thirty years, but perhaps with more hope.
Similarly, the Diocese had moved away from its 1970s policy of redundancy, and went into the business of creating benefices, groupings of parishes that shared ministers and resources. Back in the 1830s, Holy Trinity a few hundred metres to the east had been built as a chapel of ease to St Clement. This, in turn, had seeded St Luke on Cliff Lane. Like St Clement, Holy Trinity had lost almost all of its parish population, but instead of being declared redundant it was grouped into a benefice with St Luke and St Helen on St Helen's Street. For a time, the benefice took St Clement under its wing again. The church remained redundant, and was not used for regular worship, but the benefice used it for events, and in 2005 the the nave was full of seating, which any Ipswich resident would have recognised as some of the chairs formerly in the Corn Exchange.
And so it went on, St Clement attracting plenty of attention, but no permanent reuse. And yet it was clear that this fine, sound building had a role to play. St Clement is perfectly suited to the kind of performance and arts events that its new neighbours might attract, a community function in keeping with the proclaimed mission of the Diocese rather than being reused for what the Ipswich Historic Churches Trust had hoped would be 'wholly commercial' purposes. And so it was in 2015 that the building was chosen as the venue for the long awaited Ipswich Arts Centre project, designed to have a similar scale and function to the Colchester Arts Centre, which is also in a redundant church. It is hoped that work will begin in 2018. The involvement of the Borough Council and the University of Suffolk in the project leads to the further hope that, after almost half a century of waiting, the redundant medieval town centre churches of Ipswich might at last all have found permanent community reuses.
I would be very happy with your comment.

Distributing prizes and awards to winners at the annual function of ECB.
Invited to deliver talks at Rajasthan’s largest and most prestigious engineering college which is spread across 337 acres: the Engineering College of Bikaner (ECB) www.ecb.ac.in/.
ECB has around 6,000 students enrolled on its campus, out of which around 2,500 alone are in IT and Computer Science courses.
Delivered two talks on Linux and Free & Open Source Software (FOSS): ‘How to Avoid the Axe Effect’; and ‘How to Make a Dent in the Universe’. The talks were delivered at the ‘FOSS GN09 event’ which was cleverly dove-tailed with the college’s yearly techfest mega-event, called ‘Sakshama’. An ancient Sanskrit word, ‘Sakshama’ means ‘skilled; competent; adept’. The 2009 incarnation of the event, held from 28th to 31st October, was called ‘Sakshama GN09’, to highlight ‘Generation Next’. www.sakshama.org.
And what a Generation Next! They also sought my help and mentoring in launching their own on-campus Linux Users Group (LUG), www.lugb.in. Am quite impressed with their active mailing-lists and outreach activities. These guys and gals are rocking! Together with its founders, we launched LUG-Bikaner at the ‘Sakshama GN09’ event-night, on an outdoor stage in front of an audience of over 2,500.
ECB has around 1,200 computers on-campus, and with the personal laptops and desktops of students, totals at around 4,000 PCs. Till date, LUG-Bikaner has migrated over 500 computers to Linux, and still counting. Plus, they also reach out to other colleges and institutions within Rajasthan to spread the awareness of this ‘muft and mukt’ vision of computing. After all, who can understand freedom better than the royal state of Rajasthan in India?

Graphing functions can be done by using the following set of all points in the set of an equation (x, f(x)) and also define the graph of function to be the graph of the equation y = f(x). Graphing Linear Inequalities is also an important segment of graphing functions. Graphing Linear Inequalities shows an area of the coordinate plane that has a boundary line. In simple way in linear inequalities everything on one side of a line on a graph.

Received bad news this passed Wednesday, the cancer is back! We don't know where but the blood cancer markers were elevated! My oncologist send me for a bunch of test and CT Scans and Ultrasounds, repeating the blood test tomorrow just to make sure it wasn't a false positive and then we will be discussing the plan of action. Most likely will involve the dreaded chemo. Damn it!
The PF lights stick into the trans clear headlight bricks and the wires run on each side of the engineer. Finally the reason for those blue handles in the very beginning is revealed - they make it MUCH easier to mount the center brick of the lights to the base of the train without disassembling more of the walls.

DSV-3 Turtle / DSV-4 Sea Cliff
The other two 6-foot diameter HY-100 steel spheres originally fabricated for the Alvin were later used for the Navy's Turtle (DSV-3) and her sister ship Sea Cliff (DSV-4), built to a design similar to the Alvin. Turtle had video and still cameras, two six-function hydraulic manipulators, and four large view ports. Sea Cliff had two 7-function hydraulically operated manipulator arms, three 11-cm view ports, and video and still camera systems.
The US Navy’s Deep Submergence Vehicle Turtle (DSV-3) and and its sister submersible Sea Cliff (DSV-4) participated in deep-sea search and recovery, oceanographic research, and underwater archaeology. Turtle and Sea Cliff were classified as manned, non-combatant, untethered submersibles. Each vehicle consists of a 6-foot diameter spherical pressure hull mounted on a metal frame. Inside the hull are the control electronics for navigation, lighting and video, and a life support system capable of supporting a crew of three for 72 hours. Located externally on the frame are the battery and hydraulic, ballast, trim, and propulsion systems. There are also two manipulators that allow the vehicles’ crews to handle and retrieve items on the seafloor.
The vehicles were launched on 11 December 1968 and accepted by the Navy in 1970. In keeping with the Navy’s submersible tradition, they are named for towns in the United States whose names are reminiscent of the ocean or sea life. Turtle was named after Turtletown, Tennessee, while Sea Cliff’s namesake is Sea Cliff, New York.
These DSVs are constructed of a fiberglass hull over the metal crew sphere, batteries and electric motors. The craft have television and still cameras, external lights, short-range sonars, and hydraulic remote-control manipulators. Turtle weighs 21 tons, Sea Cliff weighs 29 tons. These DSVs have an endurance of 8 hours at 1 knot, or 1 hour at 2.5 knots. Due to their limited range and endurance, their mother ship should be certain to remain in the vicinity.
Many submersibles control in-water trim by shifting mercury between chambers at either end of the vehicle. Mercury is also corrosive to aluminum, extremely toxic, requires extraordinary measures to prevent spills, and is difficult to clean up when a spill occurs. The Battelle "tungsten ball trim system" is the replacement trim system for Sea Cliff and Turtle. In this system sintered tungsten balls are the weight medium, stored in two stainless steel tubing coils at either end of the vehicle which are connected by a transfer line. Hydraulic fluid moves the balls through the tubing by means of slip flow past each ball, and plastic balls on either end of the daisy chain of tungsten balls provide a filler in the transfer tube when all the weight is shifted one way or the other.
Both submersibles were initially rated for a depth of 6,500 feet but received upgrades in the early 1980s. While the Turtle was rated at 10,000 foot operating depth, Sea Cliff had her original HY-100 steel crew sphere replaced in 1983 with a titanium sphere capable of 20,000 foot operations. Sea Cliff reached this depth for the first time in March 1985, during a dive in the Middle America Trench off the Pacific coast of Central America. This increase of 1500 meters over Alvin's limits provided access to 37% more of the sea floor. Turtle reached a depth of 10,000 feet on 3 October 1980, and Sea Cliff made it to 20,000 feet on 10 March 1985. At that depth, Sea Cliff was capable of reaching 98 percent of the world’s ocean floor, an area roughly six times that of the surface of the moon. As a result, Sea Cliff enjoyed the distinction of being named flagship for the “Year of the Ocean” in 1985.
Sea Cliff and Turtle were often called upon to locate and recover Navy equipment that was lost at sea. During its 20,000 foot sea trials, Sea Cliff was ordered to the site of a downed Marine Corps Sea Stallion helicopter. Operating at 1,500 feet, Sea Cliff used its manipulators both to retrieve pieces of the aircraft directly and to attach lift lines to other parts. Sections as heavy as 10,000 pounds were recovered. Overall, 61 dives were made, and 80 percent of the aircraft was retrieved. Most importantly, Sea Cliff found and recovered the remains of the aircraft’s four crew members for family burial. Similarly, in 1995, when a Navy swimmer delivery vehicle (SDV) was lost in 814 feet of water off Hawaii, Turtle found and retrieved it in an operation many thought was impossible.
Turtle and Sea Cliff had been based from Navy Landing Ship Dock (LSD), or, more commonly, from Navy oceanographic vessels. Any of them could be transported by C-5 aircraft, although such deployments were uncommon.
Since the end of the Cold War the submersibles Sea Cliff and Turtle were available for limited academic research through a cooperative arrangement between NOAA and the US Navy's Submarine Development Squadron Five in San Diego CA. These vehicles have expanded opportunities for peer-reviewed deep submergence research off the US west coast. Sea Cliff provided the science community with some additional access to the deep sea and permitted observations to depths approaching 6000 meters, a depth range otherwise only available by using ROV Jason or the other tethered vehicles of the National Deep Submergence Facility. This increase of 1500 meters over Alvin's limits provides access to 37% more of the sea floor, which represents an area that is greater than 90% of the surface area presently exposed on the continents.
Following the Navy's decision to decommission Sea Cliff, NAVSEA requested Woods Hole Oceanographic Institution (WHOI) to provide a technical assessment and costing of how to best integrate Sea Cliff into the National Deep Submergence Facility. Perhaps the most serious and biggest impediment to integrating Sea Cliff into the US deep submergence program was the lack of an adequate and stable funding base.
Turtle was retired and loaned to the Mystic Aquarium, Institute for Exploration, where it was placed on permanent display. Sea Cliff was turned over to the Office of Naval Research and as of 1999 was being stored at the Woods Hole Oceanographic Institute while its future was debated

Australian Pelican
Pelecanus conspicillatus
Pelecanidae
The Australian Pelican is often seen around the coasts, where it can be seen roosting on sandbanks, rock platforms and reefs, or swimming in lagoons, bays and estuarine waters, dipping their oversized bills into the water to catch fish. However, on the rare occasions that monsoonal rains flood the salt lakes in the arid inland of Australia, many pelicans take advantage of the conditions and flock there in their thousands to breed. When it dries out, they leave and head for other less-ephemeral terrestrial wetlands or the coast.
Identification
Description
There are seven species of pelicans in the world, all of which are similar in shape and, with one exception, are primarily white in colour. Males are larger than females. The most characteristic feature of pelicans is the elongated bill with its massive throat pouch. The Australian Pelican's bill is 40 cm - 50 cm long and is larger in males than females. Pelicans have large wings and a wingspan of 2.3 m - 2.5 m.
Location
Distribution
The Australian Pelican is found throughout Australia, Papua New Guinea and western Indonesia, with occasional reports in New Zealand and various western Pacific islands.
Behaviour
Feeding
The bill and pouch of pelicans play an important role in feeding. The bill is sensitive and this helps locate fish in murky water. It also has a hook at the end of the upper mandible, probably for gripping slippery food items. When food is caught, the pelican manipulates it in its bill until the prey typically has its head pointing down the pelican's throat. Then with a jerk of the head the pelican swallows the prey. The bill is delicately built. The lower jaw consists of two thin and weakly articulated bones from which the pouch hangs. When fully extended, the bill can hold up to 13 litres. The pouch does not function as a place to hold food for any length of time. Instead it serves as a short-term collecting organ. Pelicans plunge their bills into the water, using their pouches as nets. Once something is caught, a pelican draws its pouch to its breast. This empties the water and allows the bird to manoeuvre the prey into a swallowing position. The pouch can also serve as a net to catch food thrown by humans, and there are sightings of pelicans drinking by opening their bill to collect rainwater.
The Australian Pelican may feed alone, but more often feeds as a cooperative group. Sometimes these groups are quite large. One group numbered over 1,900 birds. A flock of pelicans works together, driving fish into a concentrated mass using their bills and sometimes by beating their wings. The fish are herded into shallow water or surrounded in ever decreasing circles.
Breeding
Breeding depends on environmental conditions, particularly rainfall. Pelicans are colonial breeders with up to 40 000 individuals grouping on islands or secluded shores. Breeding begins with courtship. The female leads potential mates (two to eight or more) around the colony. As the males follow her in these walks, they threaten each other while swinging their open bills from side to side trying to attract the female's attention. The males may also pick up small objects, like sticks or dry fish, which they toss in the air and catch again, repeating the sequence several times.
Both sexes perform "pouch-rippling" in which they clap their bills shut several times a second and the pouch ripples like a flag in a strong breeze. As the courtship parade progresses, the males drop out one by one. Finally, after pursuits on land, water or in the air, only a single male is left. The female leads him to a potential nest site.
During the courtship period, the bill and pouch of the birds change colour dramatically. The forward half of the pouch becomes bright salmon pink, while the skin of the pouch in the throat region turns chrome yellow. Parts of the top and base of the bill change to cobalt blue, and a black diagonal strip appears from the base to the tip. This colour change is of short duration, the intensity usually subsiding by the time incubation starts.
The nest consists of a scrape in the ground prepared by the female. She digs the scrape with her bill and feet, and lines it with any scraps of vegetation or feathers within reach of the nest. Within three days egg-laying begins and eggs are laid two to three days apart. Both parents share incubation and the eggs are incubated on their feet.
The first-hatched chick is substantially larger than its siblings. It receives most of the food and may even attack and kill its nest mates. A newly hatched pelican has a large bill, bulging eyes, and skin that looks like small-grained bubble plastic. The skin around the face is mottled with varying degrees of black and the colour of the eyes varies from white to dark brown. This individual variation helps the parents to recognise their chick from hundreds of others.
The chicks leave their nests to form creches of up to 100 birds. They remain in creches for about two months, by the end of which they have learnt to fly and are fairly independent. Wild birds may live between ten and possibly 25 years or more.
