HMS Somme (1918). HMS Somme was an Admiralty  destroyer built for the Royal Navy during World War I. Commissioned seven days before the end of the war, the ship was sold for scrap in 1932.

Description
The Admiralty S class were larger and faster versions of the preceding . The ships had an overall length of , a beam of  and a deep draught of . They displaced  at normal load. The ships' complement was 82 officers and ratings.

The ships were powered by a single Brown-Curtis geared steam turbine that drove two propeller shafts using steam provided by three Yarrow boilers. The turbines developed a total of  and gave a maximum speed of . Somme reached a speed of  during her sea trials. The ships carried enough fuel oil to give them a range of  at .

The Admiralty S-class ships were armed with three single QF  Mark IV guns. One gun was positioned on the forecastle, the second was on a platform between the funnels and the third at the stern. They were equipped with a single QF 2-pounder () "pom-pom" anti-aircraft gun on a platform forward of the mainmast. They were also fitted with two rotating twin mounts for  torpedoes amidships and two 18-inch (450 mm) torpedo tubes, one on each broadside abaft the forecastle.

Construction and career
Somme, the first ship of her name to serve in the Royal Navy, was ordered on 9 April 1917 as part of the Eleventh War Programme from Fairfield Shipbuilding & Engineering Company. The ship was laid down at the company's Govan shipyard in November 1917, launched on 10 August 1918 and commissioned on 4 November, joining the 14th Destroyer Flotilla of the Grand Fleet. The Royal Navy was reorganised after the end of the First World War, with Somme joining the Seventh Destroyer Flotilla in March 1919. By January 1920, Somme had been transferred to the Mediterranean Fleet, being allocated to a reserve division of the Sixth Destroyer Flotilla.

Somme, along with sister ships  and  was ordered to join the British forces in the Black Sea on 16 January 1920 and had arrived at Constantinople by the end of the month.  She was recommissioned on 15 December 1920. The ship re-commissioned at Portsmouth with 2/5ths crew on 4 December 1923 for service with the Eighth Destroyer Flotilla of the Atlantic Fleet. Somme served on the China Station during 1927–1929 and conducted anti-piracy patrols. The ship was sold for breaking in August 1932.

SS Frank C. Ball. The Frank C. Ball was an American Bulk carrier that was built by the Great Lakes Engineering Works of Ecorse, Michigan, for the Globe Steamship Company (managed by G. A. Tomlinson, Mgr.) of Duluth, Minnesota. She was launched on December 9, 1905, as hull #14. She was powered by a 1,700 horsepower triple expansion steam engine and fueled by two coal-fired Scotch marine boilers. Even though Ball was built in 1905, she only entered service in 1906.

In 1930 the Ball was sold to the Construction Materials Corporation of Chicago, Illinois. She was converted to a self-unloading sand dredge, and repowered by a steam powered Turbo-electric engine at American Shipbuilding Company of Lorain, Ohio. She was the first commercial vessel on the lakes to use this form of propulsion. Her original engine was installed in the Ford Motor Company's former barge, the Lake Frugality, when she was requisitioned for salt water service in World War II.

J.R. Sensibar

In 1931 the Ball was transferred to the Sensibar Transportation Company of Chicago, Illinois and renamed J.R. Sensibar. She was purchased to dredge the material for Chicago World's Fair. In 1936 the Sensibar was sold to the Midwest Vessel Corporation of Cleveland, Ohio where she served for only one year. In 1937 she was sold to the Construction Aggregates Company of Chicago, Illinois. In 1941 the Sensibar was sold to the Columbia Transportation Company of Cleveland, Ohio. She was converted to a self-unloading freighter that same year. In 1957 the fleet owned by Columbia Transportation Company merged with the Oglebay Norton Corporation. In 1960 the Sensibar had a new diesel engine installed, she also had her cargo hatches raised by Christy Corporation of Sturgeon Bay, Wisconsin. In 1961 the Sensibar was lengthened to  by American Shipbuilding Company of South Chicago, Illinois.

In 1981 the Sensibar was sold to Johnstone Shipping Ltd. of Toronto, Ontario affiliate of Ship Repairs & Supplies Ltd., and renamed Conallison. She was primarily used for carrying coal from Lake Erie ports to ports on the St. Lawrence River. She did not operate through the 1982 shipping season.

Layup

In 1983 the Conallison was laid up and sold for scrap to Marine Salvage Ltd. of Port Colborne, Ontario. She was later resold to a Spanish scrapyard, leaving Quebec with the steamer George M. Carl towed by the Polish tug Koral. The vessels arrived in Avilés, Spain on September 17, 1984.

Taguig Integrated Terminal Exchange. The Taguig City Integrated Terminal Exchange (TCITX), originally conceptualized as the South Integrated Transport System (ITS-South), is a proposed intermodal transport terminal in Arca South, Taguig. It is primarily a bus terminal for buses going to and from Southern Luzon, Visayas, and Mindanao but connected to the FTI station and the under-construction Metro Manila Subway. Originally scheduled for completion by 2022, construction has yet to begin as pre-construction activities were temporarily suspended due to the ongoing COVID-19 pandemic, but it was lifted in July 2023.

History
In August 2014, five companies bought bid documents for a public-private partnership project of proposed integrated transport terminal in FTI. The five companies were given until October 2014 to submit their bids to finance, build, operate, and maintain the proposed terminal. It was then announced in January 2016 that Ayala Land won the project in November 2015.

Construction
Initially, the construction was supposed to begin in September 2016, but the groundbreaking ceremony was held in January 2018. The project would cost at least ₱5.20 billion and was expected to be operational by 2020. However, pre-construction activities were temporarily suspended due to the COVID-19 pandemic. Groundbreaking was initially scheduled in December 2024, but actual groundbreaking was held on February 3, 2025, which brought heavy traffic as the East Service Road portion in Western Bicutan was closed for the ceremony.

Cohesion number. The Cohesion number (Coh) is a useful dimensionless number in particle technology by which the cohesivity of different powders can be compared. This is especially useful in DEM simulations (Discrete Element Method) of granular materials where scaling of the size and stiffness of the particles are inevitable due to the computationally demanding nature of the DEM modelling.

Background 
In simulation of granular materials, scaling the particle size with regards to the other particles physical and mechanical properties is a challenging job. Especially in simulation of cohesive powders, lack of a robust criterion for tuning the level of the surface energy of the particles can waste enormous amount of time during the process of calibration. The Bond number  has been used traditionally in this regards, where the significance of the adhesive force (pull-off force) is compared with the particles gravitational force (weight); nevertheless, the influence of the materials properties, particularly the particles stiffness, is not comprehensively observed in this number. The particles stiffness, which is not present in the Bond number, has a considerable impact on how particles respond to an applied force. If the forces in the Bond number are substituted with potential and cohesion energies, a new dimensionless number will be formed whereby the effect of the particles stiffness is also considered. This was firstly proposed by Behjani et al. where they introduced a dimensionless number titled as the Cohesion number.

Definition and mathematical derivations 
The Cohesion number is a dimensionless number which shows the ratio of the work required for detaching two arbitrary solid particles (work of cohesion) to their gravitational potential energy as expressed below,

For example, in the JKR contact model  the work of cohesion is    by which the Cohesion number is derived as follows:

Mass can be shown in the form of density and volume and the constant number can be eliminated,

The final version of the Cohesion number is as following:

 is the particle density

 is the gravity

 is the interfacial energy

 is the equivalent Young’s modulus: 

 is the material Poisson's ratio

 shows the equivalent radius: 

This number is dependent on the particles surface energy, particles size, particle density, gravity, and the Young’s modulus. It well justifies that the materials having lower stiffness become “stickier” if adhesive and it is a useful scaling method for the DEM simulations at which Young’s modulus is selected smaller than the real value in order to increase the computational speed. Recently, a rigorous analysis of the contact stiffness reduction for the adhesive contacts to speed up the DEM calculations shows the same fractional form.

Guido Semenza. Guido Semenza (19 December 1868 – 7 November 1929) was an Italian electrical engineer, inventor, and Leonardo da Vinci scholar.

Born in London, Semenza went with his family to Italy as a child. In 1893 he graduated with an engineering degree from the Istituto Tecnico Superiore in Milan and then in 1894 graduated with an electrical engineering degree from the Institut Électrotechnique Montefiore in Liège.

He devised and put into operation the first hydro-electric plant at Paderno for the Italian Edison Co. of Milan, this work being carried out shortly after the famous experimental three-phase transmission between Lauffen and Frankfort in 1891, and the first large-scale transmission system between Tivoli and Rome in 1892. Power was transmitted from the Paderno station at 13600 volts, three-phase, and as no machinery which could work at such a pressure was then available, Semenza had himself to design suitable equipment. This pioneer work made his name famous in the electrical world, and his advice on similar problems of power supply was sought both in Italy and abroad.

In addition to his work on electrical transmission, he was also an expert in electric communication and electric traction motors. He was made a Knight of the Crown of Italy. He was president of the Italian Electrotechnical Association. He published many papers in refereed journals and from 1923 to 1927 he was president of the International Electrotechnical Commission. In 1924 he delivered the Kelvin Lecture of the Institution of Electrical Engineers, on the topic Kelvin and the Economics of the Generation and Distribution of Electrical Energy. In 1929 he was awarded the Faraday Medal of the Institution of Electrical Engineers.

Guido Semenza holds a high place among the world's electrical transmission engineers. He was the originator of the flexible pole or tower used extensively in transmission systems both in Europe and in this country.
