Zariņš discussed the unique challenges faced in developing JavaScript SDK.
Here is a brief overview of his PowerPoint presentation on ZoomCharts, the world’s most interactive data visualization software that will support all your data presentation needs with incredible speed.
What is ZoomCharts?
What defines ZoomCharts advanced data visualization software? It is NOT another HTML5 charts library. It is:
- Interactive
- Fast
- Touch enabled
- Supports big data
A long time ago
DOS 6.2 allowed for:
- 320x240x8bpp
- Direct access to pixels on screen
- Assembler for performance
Today, the Web has finally caught up in the graphics department. Now, we have access to:
- Multiple browsers and rendering technologies
- Multiple resolutions
- Performance that varies by browser and device
Development setup:
- We write in JavaScript
- Commit to GitHub
- Build system in JavaScript
- Debug in Chrome
- Run automated tests
- Like WebStorm (and Vim)
Graphics:
Canvas (fast)
SVG (slow)
WebGL (>50%)
Interactive animations:
Zoom in and out of the graph, drag and drop data, all with your mouse or trackpad.
Graceful degradation:
High FPS (frames per second) lets you scale graphics with low image degradation.
Third party libraries:
- Raphael
- Hammer.js
- Leaflet
- Moment.js
Challenges:
- Responsive design: layouts can shift and look nice on desktop screens vs. not so nice on vertical, mobile screens
- Big screen resolutions: uses devicePixelRatio for sharp rendering, but no hardware acceleration beyond 2048x2048
- Safari compatibility: with 100% CPU, input events are blocked and browser locks up; strange code offers fixes
- HTML on canvas: DOM is slow; basic HTML markup must be parsed and rendered manually; text caching helps
Support:
- Process: TrialSupportBuy
- 1 day issue resolution
- #1 Tell me what I did wrong
- #2 Can you do…
Testing:
- Automated tests on every GIT push
Automatically:
- Compare images

C-41 stand developed -- Fuji 100 film shot at ISO 100 with Voigtlander Bessa T and mostly Voigtlander Nokton 40mm f/1.4 SC classic. This was a test of diluted (1:9) c-41, stand developed at room temp (75 degrees F), for 45 minutes with 2 inversions at 15 and 30 minute marks.
The negatives were a bit funky with a dirty grey mask. I had some problem getting a good image on VueScan for a jpeg scan, however the raw scans worked well in photoshop.
Dngs in photoshop were dull, like the mask, but auto leveling brought the colors right out correctly. I dont have as much hope if one were printing.
I will try this again, I am torn between increasing the development or adjusting the EI down for more light. We will see.
The two mountains and Brith Sholem were shot with a hexanon AR 57mm f/1.4 adapted to the Bessa. There seems to be some difference in how the light landed...

Developed in the early 1950s to participate in the NATO as a lightweight fighter, the G.91 was designed by Giuseppe Gabrielli, who drew his inspiration from the F-86 Sabre, then produced under license by FIAT. While there was no follow up to the NATO, the aircraft nevertheless went into production and was ordered by both the Aeronautica Militare Italiana and the Luftwaffe; some G.91s were subsequently ceded by Germany to the Portuguese Air Force during operations in Angola. With the Aeronautica Militare Italiana the G.91 had a long career with both operative squadrons and the Country´s aerobatic team, the FRECCE TRICOLORI. The last planes were withdrawn from in 1992.

Using pioneering new technologies in Superfoods and nutrition, CFTRI has developed amazing new products which are on show at CFTRI stall at Pragati Maidan:
· Chia and Quinoa based Chocolates and Laddoos;
· Omega-3 enriched ice-cream;
· Multigrain banana bar
· Fruit juice based carbonated drinks.
New Delhi, 24th November, 2016: CSIR-Central Food Technological Research Institute (CFTRI), the premier national institute for food technology is exhibiting a range of new agri-products now grown in India, called Superfoods that bring health and nutrition best practices to everyday eating and living to the common man. The exhibits by CFTRI at the Trade Fair at Pragati Maidan in New Delhi both impress and surprise with the range and scope of their utility and potency.
The Indian population is presently going through a nutrition transition and there is an increase in incidence of diabetes, impaired heart health and obesity while there is still rampant malnutrition in the nation.
Keeping in mind an effective solution needed to address these concerns, CSIR-CFTRI is working on bringing Superfoods to the Indian population. CFTRI works on various facets of food technology, food processing, advanced nutrition, Superfoods and allied sciences. Superfoods are foods which have superior nutrition profiles which upon regular consumption can help improve health and wellness of the consumer.
CFTRI has developed the agro-technology for growing Superfoods viz. Chia and Quinoa in Indian conditions. Chia is the richest source of omega-3 fats from a vegetarian source and Quinoa has excellent protein quality and low glycemic load carbohydrates. Comprehensively, Chia and Quinoa have potential to improve population health and both blend seamlessly into traditional food preparations.
CSIR-CFTRI also infuses the spirit of entrepreneurship in their students. One of the doctoral students after completing her academic program started her own technology provider start-up company, Oleome Biosolutions Pvt Ltd. In a global first, CSIR-CFTRI in collaboration with Oleome, has developed a 100% vegetarian, Omega-3-enriched Ice cream called “Nutriice” using Chia oil.
CSIR-CFTRI is also in the process of the final phase of testing of diacylglycerol (DAG) oil, a unique cooking oil that has “Anti-Obesity” functionalities. One can consume it as part of daily regular diet and while the oil is available as energy but does not get stored as fat in our bodies. The final phase of human clinical trial is presently under progress.
CFTRI has also designed and developed snacks with advanced nutrition designs to support the nutrition needs of growing children. These have been implemented in the aganwadi levels to complement the existing government mid-day meal and will be scaled up soon. The products, such as Nutri Chikki with spirulina, rice beverage mix, high protein rusk, energy food, nutri sprinkle, seasame paste and fortified mango bars have been well received by the children and the anganwadis alike. Multi-grain Banana bar is a new addition to in this product portfolio.
Another exciting area of multidisciplinary research being done at CSIR-CFTRI is on nanotechnology, food technology and nutrition. Nanomaterials are known for their characteristic properties and CSIR-CFTRI is working on the use of nanoparticles for various applications. One of our interesting developments is the design and development of food packaging material with nanoparticles with antimicrobial and antioxidant properties to improve shelf-life of processed foods.
CSIR-CFTRI is also working on “Smart Foods” to answer specific needs of the consumer. These promising and specifically designed innovations are being developed for better sleep, better skin health, improved digestion, better cognitive performance and better stress management. The high science is brought into a simple food product, like a cereal bar which helps one to be more attentive over the day, or a unique dosa mix that helps in working out better at the gym with lower perceived exhaustion and even a special soup to help sleep better at night!
Speaking on the sidelines of the CSIR-CFTRI exhibition at Pragati Maidn, Prof. Ram Rajasekharan, Director, CFTRI said “Our mandate is to find innovative solutions to India agricultural and nutritional challenges. Our aim is to develop products to make Indian agriculture productive, efficient and at a consumer level gradually replace drugs with foods that will promote better health and wellness. We strive to deliver our best in improving food security and nutrition security, also developing a stronger, smarter and healthier India”.

Nothing you see here is real, even though the conversion or the presented background story might be based on historical facts. BEWARE!
Some background:
he need for a specialized self-propelled anti-aircraft gun, capable of keeping up with the armored divisions, had become increasingly urgent for the German Armed Forces, as from 1943 on the German Air Force was less and less able to protect itself against enemy fighter bombers. Therefore, a multitude of improvised and specially designed self-propelled anti-aircraft guns were built, many on the Panzer IV chassis, starting with the Flakpanzer IV Möbelwagen (a stopgap design) and progressing through the Wirbelwind and Ostwind models. However, these designs were tall, open-topped designs with sub-optimal armor. These flaws were to be eliminated in the Kugelblitz, the final development of the Flakpanzer IV.
The first proposal for the Kugelblitz SPAAG envisioned mounting a modified anti-aircraft turret, which had originally been developed for U-boats, on the Panzer IV chassis. It was armed with dual 30 mm MK 303 Brunn guns. However, this was eventually abandoned, since development of this gun had not yet been completed, and, in any case, the entire production run of this weapon turret would have been reserved for Germany's Kriegsmarine, anyway. However, enough firepower that enabled the Flakpanzer to cope with armored attack aircraft, namely the Soviet Ilyushin Il-2, which was a major threat to German tanks, was direly needed.
As the best readily available alternative, the SdKfz. 161/7 Leichter Flakpanzer IV 3 cm, nicknamed “Kugelblitz” because of its unique turret design. It comprised 30 mm MK 103 cannon in a Zwillingsflak ("twin flak") 103/38 arrangement, and it combined the chassis and basic superstructure of the existing Panzer IV medium battle tank with a newly designed turret. The turret’s construction was sophisticated and comprised a spherical body, which was protected with 20 mm steel shells in front and back. This core was hanging in a ring mount from the Tiger I, suspended by two spigots – it was effectively an independent capsule that only slightly protruded from the tank’s upper side and kept the vehicle’s profile very low, unlike its predecessors. Elevation of the weapons (as well as of the crew sitting inside of the turret!) was from -5° to +80°, turning speed was 60°/sec. The turret was fully enclosed, with full overhead protection, 360° traverse and (rather limited) space for the crew of three plus weapons and ammunition. Compared with all earlier SPAAG designs, the Kugelblitz turret was a fundamental step ahead.
The tank’s MK 103 was a powerful weapon that had formerly been fitted in single mounts to such planes as the Henschel Hs 129 or Bf 110 in a ventral gun pod against tanks, and it was also fitted to the twin-engine Dornier Do 335 heavy fighter and other interceptors against Allied bombers. When used by the army, it received the designation “3 cm Flak 38”. It had a weight of only 141 kg (311 lb) and a length of 235 cm (93 in) with muzzle brake. Barrel length was 134 cm (53 in), resulting in Kaliber L/44.7 (44.7 caliber). The weapon’s muzzle velocity was around 900 m/s (3,000 ft/s), allowing an armor penetration for APCR 42–52 mm (1.7–2.0 in)/60°/300 m (980 ft) or 75–95 mm (3.0–3.7 in)/ 90°/ 300 m (980 ft), with an effective maximum firing range of around 5.700 m (18.670 ft).
The MK 103 was gas-operated, fully automatic and belt-fed, another innovative feature at that time for AA guns, which were formerly fed only by ammunition clips that had frequently to be manually re-loaded and prevented continuous fire for more than a few seconds. In the Kugelblitz turret the weapons could be fired singly or simultaneously, and their theoretical rate of fire was 450 rounds a minute, even though 250 rpm in short bursts was more practical to save ammunition and prevent overheating. The total ammunition load for both weapons was 1,200 rounds and the discharged cases fell into canvas bags placed under the guns, to be collected and recycled (due to material shortage). Since the MK 103 cannons produced a lot of powder smoke when operated, fume extractors were added, which was another novelty.
A production rate of 30 Kugelblitz SPAAG turrets and the respective conversion and production of complete vehicles on the basis of Panzer IV hulls per month by December 1944 was planned, but never achieved, because tank production had become seriously hampered and production of the Panzer IV was about to be terminated in favor of the new E-series tank family. Therefore, almost all Flakpanzer IV with the Kugelblitz turret were conversions of existing vehicles, mostly coming from repair shops after having been damaged in the field.
In parallel, work was under way to adapt the Kugelblitz turret to the Jagdpanzer 38(t) Hetzer hull, which was still in production in the former Czechoslovakian Skoda works, and to the new, light E-10 and E-25 tank chassis. Since the production of the new types also did not gain momentum, a new and immediate interim solution was required to provide the tank units with mobile protection from enemy aircraft. As another stopgap solution, hulls from standard SdKfz. 171 “Panther” medium battle tanks were modified to accept the Kugelblitz turret.
These vehicles were almost exclusively revamped or unfinished battle tanks, mostly late “G” models, but early “D” and “A” models were also converted, lending them a second life. The adaptations were minimal, though, and were executed at Kosmonosy, the former Skoda works, where Kugelblitz conversions were concentrated. The modified vehicle received the official designation SdKfz. 171/4.
The Panther’s original turret ring had to be exchanged, and its’ diameter enlarged to take the Tiger I’s turret bearing. Another factory modification for the SPAAG role included additional armor plates over the ventilation grilles on the top of the engine deck, to better protect the powerplant from aircraft attacks. Theoretically the Panther’s side skirts were supposed to be mounted on the SdKfz. 171/4, too, to protect its weak spot in the side armor around the running gear, but lack of material and rushed production simply prevented this. However, the side skirts were, when available, sometimes retrofitted in the units’ field workshops.
Driver and radio operator were in the front of the hull, as with all German tanks. In the turret, the commander/gunner, who had a small observation cupola on top of the turret, was positioned in the middle, behind the main guns. The two gunner assistants were placed on the left and right side in front of him, in a slightly lower position. The assistant situated on the left of the guns was responsible for the turret’s movements, the one on the right side was responsible for loading the guns. The spare ammunition was located on the right side. Each of these three crew members had individual hatch doors, which they could use to enter or exit the vehicle. The gunner assistants’ hatch doors each had a small round shaped extra hatch, which were used for mounting sighting devices.
Additionally, to improve accuracy and save ammunition, plans were made to outfit the turret with a stereoscopic telemeter for the commander – due to the lack of resources only about 1 in 4 turrets received this device, though, and such vehicles were reserved for platoon leaders. The stereoscopic telemeter was like an earlier stereoscopic rangefinder, but only with a single eyepiece. Since the original Kugelblitz turret offered not enough space for the device’s integration it was added to a new, more bulbous hatch for the commander and mounted externally in an armored horizontal fairing. Vehicles with the rangefinder device received an “Ausf(ührung) B” suffix.
When Einheitspanzer production gained momentum the Panther conversions into SdKfz. 171/4 and other SPAAGs like the SdKfz. 171/3 ‘Coelian’ vehicle family were stopped. Roundabout 50 SdKfz. 171/4s reached frontline units, only a dozen of them of the Ausf. B with the stereoscopic telemeter device. By mid-1945 the Panther-based SPAAGs had gradually replaced most of the outdated Panzer IV AA variants and other earlier improvised SPAAGs with open turrets. However, the SdKfz. 171/4 SPAAGs were soon joined and replaced by the newly produced, dedicated Flakpanzer variants of the new Einheitspanzer family, and already phased out by mid-1946, when Panther spare parts ran low and to unify and simplify field logistics with the new generation of standard tanks.

The kit and its assembly:
To be honest, this was a rather uninspired build. It was spawned by the thought that the Panzer IV-based “Kugelblitz” SPAAG might have been (re)built with a later/gigger chassis, too, and the Panzer V Panther appeared like a logical chassis. I had a Hasegawa Panther Ausf. G in The Stash™, as well as a surplus Kugelblitz turret from a ModelCollect fictional E-Series walking tank (a standard feature of the se kits in a ventral position, what makes NO sense at all!), and mating these was a rather simple task.
The Kugelblitz turret was built OOB, but to make it look a bit different and special I added a scratched rangefinder to the commander’s hatch, which now turned into a kind of cupola.
The Hasegawa Panther was built OOB, the only mods I made are armor overs for the engine deck louvres, I left away the standard side skirts, and instead of the tube for a replacement 75mm gun barrel I gave the model a pair of thinner tubes for the smaller and shorter 30mm MK 103 barrels. To accept the new turret the original hull opening had to be enlarged – a bit tricky, but it worked well. Additionally, I scratched folded tarpaulins for the rear flanks, filling “blank space”. Another addition is a standard whip antenna on the engine deck, made from heated black sprue material.
Painting and markings:
A whiffy vehicle deserves a rather “typically German” livery, and I went for another variant of the Hinterhalt scheme, with the standard colors of Dunkelgelb (RAL 7028), Olivgrün (RAL 6003) and Rotbraun (RAL 8012). Painting started, as in real life, with an overall coat of Dunkelgelb, with Tamiya TS-3 from a rattle spray can. On top of that I added green and brown “tiger stripes” with Revell 84 (Lederbraun) and added smaller mottles with Revell 361 (Olivgrün). I did not pay much attention on being exact, since this field camouflage was improvised in real life, too, and it would disappear under a coat of winter whitewash, anyway. To emphasize the SPAAG’s makeshift origin, I painted the turret cell in simple Oxidrot overall (RAL 3009, a standard German primer tone in WWII, even though frequently lighter due to be being stretched with pigments) and just applied some dry-brushing, while the armor collar received the hull’s Hinterhalt cammo, too.
The whitewash was done with thin acrylic Revell 5 (Flat White), only for a worn coat so that the dark cammo stripes and mottles underneath would shine through here and there. The tactical markings were spared from the whitewash, though, consisting of red code numbers from the Hasegawa kit’s sheet and the scrap box. The OOB black vinyl tracks were also painted/weathered, with a wet-in-wet mix of black, iron, and red brown, all acrylics to avoid chemical long-term reactions with the relatively soft material through solvents.
Everything was sealed with matt acrylic varnish, and after the vinyl tracks had been mounted I also added lumps of snow to the running gear and the tracks (wet white tile grout, partly mixed with fine brown sand) and dusted dry white tile grout over the model to simulate light patches of snow, but not a full coat.

NORWALK – As school districts unfold their Teacher Leader Compensation (TLC) programs, they would do well to drop by Norwalk to see what this district is up to.
Now in its second year of implementation, the district has found that its program is not static. Far from it. Leader titles have changed as needs became more focused. And, indeed, some of the leaders have changed.
“Our TLC is constantly focused on the ongoing needs; it doesn’t stay in one place,” said Dawn Schiro, elementary director of teaching and learning. “We sit down with every group and all grade levels and get all of the feedback on what changes we need to make to ensure all needs are being supported.
“Since we first implemented TLC, we have changed job descriptions. We realized technology is huge so we now have a technology component. Some of the roles we had at the beginning we changed. It is ever adjusting. I don’t know if it will ever be the same from year to year.”

The Mills No.36 Grenade was developed in May 1918, at the end of World War One, by British industries and is referred to as the “Mills Bomb”. It has a time delay of 4 or 7 seconds depending on the version. On the Great War Battlefields, the Germans sometimes returned the British Grenades with a delay of 7 seconds. They were the first modern Fragmentation Grenades used by the British Army.
William Mills, a Hand Grenade designer from Sunderland, patented, developed and manufactured the ''Mills Bomb'' at the Mills Munitions Factory in Birmingham, England, in 1915. The Mills Bomb was inspired by an earlier design by Belgian Captain Leon Roland, who later engaged in a patent lawsuit. Col. Arthur Morrow, a New Zealand Wars Officer, also believed aspects of his patent were incorporated into the Mills Bomb. The Mills bomb was adopted by the British Army as its Standard Hand Grenade in 1915 as the No.5.
During World War Two, only the 4 second versions were produced and endowed in the British Army. Its serrated shape allowed to produce a very large number of shrapnels during the explosion, which would cause a maximum of damage. Mills Bomb No.36, was in service with the British Army until the 1960's, is known as “pineapple” due to its serrated structure.

"James Gow Mann was the Master of the Armouries at the Tower of London from 1938 until his death in 1962, and an acknowledged expert in the field of arms and armour.
Mann was born on the 23rd of September 1897 in London. His father was Alexander Mann, a Scottish landscape painter. He was educated at Winchester School and it was then that he first developed an interest in arms and armour. He delayed going to University, joining the army instead, and during the First World War he served as an officer in the Royal Artillery seeing service on the Italian/Austrian front. Whilst serving on the Italian front he spent his leaves visiting cities which had museums and collections of arms and armour. He enjoyed army life and after the war became an avid reader of World War I books and he loved to tell tales of the campaigns in Flanders and at Vittorio Veneto. His war time experiences gave him an understanding of the art of war as well as helped him develop a sense of command. After the war he studied at Oxford, attending New College. His thesis, The evolution of defensive armour in England, France and Italy during the first half of the 14th Century, was supervised by Charles ffoulkes, the then curator of the Tower Armouries. A copy of his thesis can be found in the Royal Armouries Archives. ffoulkes introduced Mann to Viscount Dillon (ffoulkes' predecessor) and to the Baron de Cosson. Mann's relationship with the Baron de Cosson was one of the most influential of his life. De Cosson and Mann would frequently meet and discuss earlier collectors and collections of arms and armour, one specific collection being the votive armours at Madonna della Grazie. When the Baron died, his family asked Mann to arrange for the publication of de Cosson's Dictionary of Arms and Armour and they offered Mann his choice of any books in the Baron's library. Unfortunately, the Dictionary of Arms and Armour was never published, but the index can be found in the Royal Armouries library. Many of the books in the Royal Armouries Archives bear de Cosson's bookplate, obtained via James Mann's personal library.
After leaving New College his first posts were in the field of wider fine arts. He accepted an appointment in 1922 in the Art Department of the Ashmolean Museum with the art historian Charles Francis Bell. One of his first tasks was calendaring prints left by Francis Douce, the early 19th century antiquary. Douce's collection was rich in prints of medieval life and customs. This certainly appealed to Mann's growing fascination of arms and armour. In 1924 he moved to London to a post as an assistant to Mr S J Camp in the Wallace Collection, again in the field of fine arts. He produced a sculpture catalogue, which was acclaimed as a remarkable first achievement. He worked at the Wallace Collection for six years and during this time he published some of the work which established his reputation as a historian of armour. In 1929 he worked on and edited the first translation of the catalogue of the historic Trapp armoury at Churburg, his first published contribution to the study of arms and armour. In 1930 he published the first detailed description of the votive armours in the church of the Madonna della Grazie, which had been brought to his attention by Baron de Cosson. de Cosson suggested to Mann that the votive figures warranted a closer inspection and Mann discovered a rare group of 15th century Gothic armours. The armours were stood in niches around the walls, and thought to be made of wax, clad in carta pasta or 'papier-mache' armour. The armours were in fact genuine, covered with dust and rust. Mann spent a series of summer holidays taking the figures down and cleaning the armour. His results appeared as a series of articles in Archaeologia. His findings increased the total of surviving suits of Gothic armour by a third.
Mann was finding his post at the Wallace Collection increasingly frustrating as the arms and armour collection was under the care of S J Camp. In 1931 it was suggested that he apply for the Keepership of the Art Department of the Ashmolean Museum, to succeed C F Bell. He declined as he felt his interests were in centred in London. He was appointed to the post of Deputy Director of the newly established Courtauld Institute of Art and he became a Reader in the History of Art at London University. Mann's work at the Courtauld consisted largely of lecturing although he did find time to arrange part of an exhibition at the Royal Academy. He gave a series of lectures on armour connected with his findings in the church of Madonna della Grazie, but was unable to concentrate on his main interest of armour.In 1936 an opportunity finally presented itself. S J Camp was leaving his post at the Wallace Collection and Mann was offered the post of Keeper of the Wallace Collection on a 5 year contract.
In 1938 Charles ffoulkes retired as Master of the Armouries. Mann immediately requested permission from the Trustees of the Wallace Collection to apply for the post. The post was part time and virtually unpaid. He was to hold the post in conjunction with his work at the Wallace Collection. He got the necessary approval and was subsequently appointed. On the eve of an outbreak of World War II Mann found himself making arrangements for the evacuation of the contents of the Armouries rather than planning for a redisplay of the collection. Plans for the evacuation of national treasures had been well under way since 1933, but the then curator of the Armouries, Charles ffoulkes felt there would be no need to evacuate the contents. However, in August 1939 the packing began. Some of the armour was stored at Hall Barn in Beaconsfield for the duration of the war, but in May 1940 four armours of Henry VIII and other fine armours were put on show in the National Museum of Wales in Cardiff. Later in 1940 after a series of bombing raids at the Cardiff Docks the armour was moved to Caernarvon Castle where it was joined by more items from the Tower in London. Mann stayed in London for the duration of the War, but made long visits to Hall Barn and occasional ones to Caernarvon Castle. During the war Mann was vilified in the press for attempting to save ornamental and historical ironwork from being melted down to aid the 'war effort.' He tried to publicize the historical value of items such as iron railings and the trophy cannons displayed in various towns and cities. Mann gave occasional lectures on the history of firearms and arms and armour to the troops and he continued to publish. In 1940 he delivered a lecture on The Etched Decoration of Armour to the British Academy. This lecture opened an unexplored field of research by linking the art of the armourer with the early history of engraving. In May 1944 Mann was appointed as Hon. Secretary to a committee that was set up to consider the problem of works of art looted by the Nazis. He visited Paris and inspected the state of the newly liberated Paris museums. He found that the Germans had kept the Musee del Armee open during the war, using the upper galleries for barracks. There were bullet holes in glass cases, but the contents were virtually unharmed. Throughout the war he was involved in planning for the post-war museum world. In 1944 he became Director of the Society of Antiquaries, in charge of the research and publications programme, and in 1949 became President. In Spring 1945 the arms and armour started to return from their places of safety. The last delivery from Hall Barn was made at the end of June, with work on the redisplay starting in July. 4 rooms of the Tower were reopened to the public on the 1 January 1946, with 2,500 visitors, 2,700 on the next day, and on the12th of January it recorded 10,000 visitors.
Throughout his life Mann corresponded with other collectors and historians of arms and armour. As mentioned he had connections with the Baron de Cosson and Charles ffoulkes. He also corresponded with F H Cripps-Day as well as advised Edward Barry and R L Scott on their acquisitions. He catalogued Barry's collections and helped Scott build up a collection which is now in the Glasgow Museum and Art Gallery. He was involved with Paul Post, a German scholar and curator of the Berlin Arsenal. Post's position was made difficult during the 1930's because his wife was part Jewish. Mann welcomed Post's son to London and helped him gain admittance to a British medical school to continue his studies as he was unable to do so in Germany. Mann's legacy includes many administrative improvements made at the Tower of London as well as significant acquisitions. He died in 1962."

Brief introduction:
MTW SERIES EUROPEAN TECHNOLOGY TRAPEZIUM MILL--the latest grinding equipment, with its own knowledge patents, have reached modern advanced level in the world. This series mill absorbing the European advanced technology and many engineers' ripe experience, combining the actual requirement and proposal of our 9518 customers', have been developed on the basis of our professional engineers' hard researching. MTW SERIES EUROPEAN TECHNOLOGY TRAPEZIUM MILL adopts bevel gear overall drive, inner automatic Thin-Oil lubricating system, arc air channel and several latest patent technology.
Usage:
MTW SERIES EUROPEAN TECHNOLOGY TRAPEZIUM MILL is mainly used to grind minerals in the field of metallurgy, construction, chemical industry, mining, etc., including lime stone, quartz, feldspar, calcite, talcum, barite, fluorite, thulium，marble, porcelain, bauxite, manganese, iron ore, copper ore, phosphorite, ferric oxide(red), zirconium, slag, active carbon, dolomite, granite, ferric oxide(yellow), bean cake, fertilizer, compound fertilizer, coal ash, soft coal, lignite, magnesite, chrome oxide, gold mine, red mud, clay, kaolin, coke, china clay, kyanite, fluorite, rhyolite, greenstone, shale, basalt, gypsum, graphite, carborundum, heat-retentive materials which are non-flammable, non-explosive, with Moh's hardness below 9 and moisture below 6%.
The new technology as below:
1) Bevel gear overall drive: the traditional grinding mill is driven by speed reducer and coupling. It is hard to be installed. And there will be too much noisy, and the efficiency is lower. MTW series mill is driven by bevel gear, so its structure is compacter, easy to be installed and more efficient.
2) Inner automatic Thin-Oil lubricating system: the traditional mill adopts grease lubrication, so the lubricating resistance is stronger, the temperature will be higher soon, the bearing life is shorter. MTW series mill adopts inner L.O. pumps, so the main shaft bearing and bevel gear can be lubricated without an additional lubrication system.
3) Arc air channel: all of the air channel of traditional grinding mill is upright board type. In this case, there will be stronger resistance when the air impacts the air channel board, and the energy of collisions of air molecules loss heavily, as a result, the air channel will be jammed easily because of the eddy air flow. MTW series mill adopts a cambered air channel, the tangential air goes into air channel easily because there is small resistance. And the inner outlet is very good for the grinded material to spread around and avoid grinding material jammed.
4) Cambered shovel with renewable edge: The traditional shove is integral and edge always be worn out quickly, so you have to renew it in short time which affects the working time and wastes too much steel. The shovel edge of MTW series mill adopts high wearable limit alloy, its life will be longer. You only want to change the edge, not the whole shovel. so the steel material is saved. In addition, because the traditional shovel is plane type, the grinded material stacks on the same plane when it is scooped up. So the middle parts of the roller is worn out heavily. But the cambered shovel can scoop up the grinded material in the same vertical plane, that makes the rollers and ring worn equally. At the same, the grinding efficiency is higher and capacity is higher;
5) Separated cyclone: There is a separated structure between inner piping and mixed air and powder. The efficiency and precision of classifying is promoted highly;
6) No resistance snail shell (small checking door so that there is not an eddy air flow): In the traditional grinding mill, the checking door of snail shell is prominent, that mean the checking door and snail shell are not on the same plane. So there will be eddy air flow easily come into being. As a result, the energy waste is bigger. MTW series mill make the inner surface of checking door stay with the inner surface of snail shell on the same plane, so the eddy air flow is avoided efficiently;
7) Perfect outward appearance: Both of the inner parts and outer part of the MTW series mill adopt advanced structure and beautiful arc structure design. This makes the mill advanced and beautiful.
this isn't a test but smoke clouds are infinate i adore rain love awkward stories

Fuji Acros ISO 100 black and white negative film, developed in Rodinal.
This is the rack which goes inside the Dallan Developing Tank. The 12 little arched frames each hold a sheet of film and are loaded in the dark, which, after I'd gotten the hang of it, became much easier than I expected. I'm guessing that the rack may have originally held 6.5 x 9 cm glass plate negatives for development.
I use this tank to develop 6.5 x 9 cm sheet film shot in my Kodak/Nagel Recomar 18.
In this shot, the Dallan film rack is posing on the home-made plywood tripod platform that i made for my box cameras.
Shot with Uncle Shoe's studio strobes in his studio. I also borrowed his Nikon FM2 for the shoot; shot on Kodak Portra 160VC.
To develop the park began in 1976, the 200th anniversary year of American independence, to celebrate the relationship between the two freedom-loving countries, Israel and the US. The forest developed and extended an existing woodland planted in the region in the 1950s by new immigrants from the surrounding area and nearby Beit Shemesh, who had arrived soon after the founding of the State of Israel.
Look at these Prices to develope Film!! My God! Thank goodness for Digital Cameras. $19.00 for 36 exporsure! Wow!
I guess Because it's such a "nichte" industry now. I haven't develope any Film in Years. thinking of "Fireing" up the Old Nikon N50 Film Camera. which i Love. I Have a Special Place that developes Film. if they are Still there!
In February 1943, construction was begun in Oak Ridge on a graphite pile, which had been given the code name X-10. Though X-10 was under the jurisdiction of the University of Chicago, the staff was made-up largely of DuPont people. Everything connected with the project was kept secret;all classified materials were referred to by code name only. The English code name for uranium was "tuballoy."
The X-10 pile was still under construction when DuPont suddenly decided to switch to the water-cooling method & develop the model conceived by Dr. Eugene Wigner & his group. This was a major decision, announced by Crawford Greenewalt only after the company's careful study of the different methods. Work on helium cooling was abandoned, & the efforts of DuPonts's Design Division were concentrated exclusively on Wigner's model. Thus, the plutonium project followed a peculiar pattern: design & development were carried-out at the same time as the construction of the real plant & the building of the pilot plant. X-10 was completed in November, & although it could not serve as pilot for Hanford reactors, it produced small amounts of plutonium invaluable to the Los Alamos scientists as a research tool."
