MV Mega Bakti. MV Mega Bakti is a submarine rescue ship operated by the Royal Malaysian Navy (RMN). The ship was specially designed and built by Keppel Singmarine for use in Malaysia.

Development
Keppel Singmarine signed a contract with the RMN on 12 July 2012. The RMN officially received Mega Bakti on 24 September 2013 and placed her under the RMN Submarine Headquarters (MAKS) based on Sepanggar in Sabah. The ship is designed to be surface support vessel for submarine rescue and offers its services in two forms. The head of operations (SMER-I) is charged with demonstrations and training; other operations include training ship divers, search and rescue (SAR), torpedo recovery.

Characteristics
The ship is fitted with a double lock decompression chamber (DDC) and global positioning system intelligent buoy tracking system (GIB), and a remotely-operated vehicle (ROV). The ROV is controlled remotely by operators via a cable connected to the Mega Bakti. During a rescue operation, the ROV is used to install the distressed submarine ventilation and depressurization system (DSVSD) at a depth of up to 400 meters. It is capable of cleaning the obstacles at the escape hatch of a submarine-in-distress (DISSUB), capturing photos and videos and sending emergency life support stores (ELSS) pods. The ELSS Pod is used as a medical aid, food and other necessities to DISSUB using the ROV. Mega Bakti provided 12 ELSS pods capable of accommodating pressures of 65 bar. The GPS intelligent buoy is used to detect DISSUB positions stranded at sea and can detect up to 1,000 meters.

The distressed submarine ventilation and depressurization system (DSVSD) is installed on DISSUB to discharge clean air and drain out contaminated air from DISSUB. This system has been used by the French Navy and can reach depths of 250 meters. The double lock decompression chamber (DDC) is used to treat submarine crews with decompression sickness (DCI). Mega Bakti has 2 DDC units that can treat 6 patients in each DDC unit.

The portable underwater telephone system is also used to carry out communication between Mega Bakti and a DISSUB.

Mega Bakti has two fast rescue boats to perform submarine crew rescue operations at any time and is an intermediary element of communication between parent aircraft and DISSUB.

Missions

In 2014, Mega Bakti was deployed to search the missing Malaysia Airlines aircraft, MH370 that was missing in the Indian Ocean. This mission is the first her deployment.

In 2021, Mega Bakti is en-route again to search for the missing Indonesian Navy submarine after , went missing off the waters of Bali during a torpedo drill, and reached the scene on the 25th of April 2021.

Georg Wulf. Georg Wulf (1895-1927) was a German aviation pioneer and aircraft manufacturer.

Biography 
Wulf was born 17 May 1895 in Bremen. He was the son of a customs agent. He attended the high school on Dechanat Street.

Around 1910, Henrich Focke, with the help of his brother Wilhelm Focke, built a simple canard airplane of steel tubes and bamboo. It was powered by an eight-horsepower engine. Their attempts to fly on the Bremen paradeground failed, but they awoke an interest of the 15 year old Wulf.

Wulf was so enthusiastic about flying that he quit before he graduated from high school and instead made airplanes. He offered to work with Focke, which Focke accepted. Starting in 1911, Wulf and Focke designed aircraft and built them with the simplest means. In 1912 they completed a flyable monoplane, which Wulf flew.

The treaty ending World War I prohibited aircraft with engines from being built in Germany, until 1923. But Wulf and the Focke brothers secretly continued to build their aircraft in the basement of the Focke family house.  After 1921 Wulf flew the aircraft they built. In 1923 Wulf also worked as a flight instructor. Also in 1923, the "'Bremen Aircraft Construction Company (Bremer Flugzeugbau-Gesellschaft) was founded by Focke and Wulf, which was renamed  Focke-Wulf- Aircraft Construction Inc. (Focke-Wulf-Flugzeugbau AG) a year later. Wulf was the managing director, the technical director of operations, and a pilot.

As a preliminary study, they had built a light monoplane, which first flew in November 1921. This was followed by the known under the name  Seagull  and  duck  commercial aircraft.

Death
On September 29 1927, Wulf died while testing a prototype of the F 19a Ente aircraft.

Wulf is buried in Bremen in the Osterholzer cemetery (field E), near the bridge to the North Chapel.

Honors 
 In the district of  Bremen-Neustadt the Georg-Wulf-Straße was named after him in 1955 near Bremen Airport.
 The "Georg-Wulf-Straße" in Berlin-Schönefeld bears his name.

1-Naphthalenethiol. 1-Naphthalenethiol is an organosulfur compound with the formula C10H7SH.  It is a white solid.  It is one of two monothiols of naphthalene, the other being 2-naphthalenethiol.

Synthesis
A practical synthesis involves the tin/HCl-reduction of the naphthalene-1-sulfonyl chloride.
1-Naphthalenethiol can also be prepared from 1-bromonaphthalene by Pd-catalyzed reaction with the silylthiolate iPr3SiSK followed by hydrolysis of the silathioether.  It was first prepared from the Grignard reagent generated from 1-bromonaphthalene.  Treatment of that reagent with elemental sulfur followed by acidification gave the compound. It has been produced by the iodine-catalyzed reduction of 1-naphthalenesulfonic acid with triphenylphosphine.

Reactions
Treating 1-naphthalenethiol with butyl lithium in the presence of tmeda affords the 2-lithio derivative.

Naphthalene-1-sulfonic acid. Naphthalene-1-sulfonic acid is an organic compound with the formula C10H7SO3H.  A colorless, water-soluble solid, it is often available as the dihydrate C10H7SO3H.2H2O.  It is one of two monosulfonic acids of naphthalene, the other being the more stable naphthalene-2-sulfonic acid.  The compound is mainly used in the production of dyes.

Naphthalene-1-sulfonic acid undergoes many reactions, some of which are or were of commercial interest.  Upon heating with dilute aqueous acid, it reverts to naphthalene.  Fusion with sodium hydroxide followed by acidification gives 1-naphthol.  Further sulfonation gives 1,5-naphthalene-disulfonic acid. Reduction with triphenylphosphine gives 1-naphthalenethiol.

Elias Willard Smith. Elias Willard Smith (1814/1816–1886) was an American architect and civil engineer.  He was born in 1814 or 1816 (sources differ) in Albany, New York, and died in 1886 in Washington, DC. He was educated as an engineer, at the Rensselaer Polytechnic Institute. As a graduation present from his father, he undertook a trip from St. Louis to the Rocky Mountains and back (1839–1840). During this trip, he recorded his observations in a journal, which was handed down in his family and later published in various scholarly venues.

After returning from the Rocky Mountains expedition and until the Civil War, Smith practiced engineering, having some connection with the water works in Detroit and Chicago. While living in Detroit, Smith practiced architecture, and notably Dankmar Adler studied with him before 1861. After the Civil War, he moved to Virginia, first to Williamsburg and then to Georgetown. During this period he performed some work for the Washington Gas Works.

In 1865, Smith designed the Daniel S. Schanck Observatory for Rutgers College (now Rutgers University).

Naphthalene-2-sulfonic acid. Naphthalene-2-sulfonic acid is an organic compound with the formula C10H7SO3H.  A colorless, water-soluble solid, it is often available as the mono- and trihydrates C10H7SO3H.2H2O.  It is one of two monosulfonic acids of naphthalene, the other being naphthalene-1-sulfonic acid.  The compound is mainly used in the production of dyes via nitration en route to aminonaphthalenesulfonic acids.  The compound is prepared by sulfonation of naphthalene with sulfuric acid, however under equilibrating conditions that allow the 1-sulfonic acid isomer to convert to the more stable 2-sulfonic acid. 

Naphthalene-2-sulfonic acid undergoes many reactions, some of which are or were of commercial interest.  Fusion with sodium hydroxide followed by acidification gives 2-naphthol. It is an intermediate in the formation of 2,6-, 2,7- and 1,6-naphthalene disulfonic acids as well as 1,3,6-naphthalenetrisulfonic acid.  Naphthalene-2-sulfonic acid condenses with formaldehyde to give polymeric sulfonic acids.

Architectural and Engineering Works Department. The Architectural and Engineering Works Department was the main civil engineering department of the British Royal Navy responsible constructing, and maintaining naval buildings, dockyards, ports and managing civil engineering staff from 1837 to 1919 it was superseded by the Civil Engineer in Chief's Department.

History
A specific post with responsibility for the navies expanding civil works programs led to the creation of an Inspector-General of Naval Works in 1796 who's managed civil engineering works in the dockyards under the supervision of the Navy Board. In 1813 the department was renamed to Department of the Surveyor of Buildings administered by the Surveyor of Buildings. Following the abolition of the Navy Board the department was placed under Admiralty control. In 1837 the department, it was renamed the Architectural and Engineering Works Department under a then new Director of Works responsible to the Civil Lord Civil Lord of the Admiralty who managed the Royal Navy's buildings and works departments and land estates. . In 1919 the department was renamed the Civil Engineer in Chief's Department. In January 1960 it became the Navy Works Department under a Director-General, Navy Works. In April 1963 the department ceased to exist when responsibility for building and civil engineering works for the armed services was transferred to the Ministry of Public Building and Works, later Department of the Environment.

GSR Class 700. The Great Southern Railways (GSR) Class 700 consisted of five 0-6-0 locomotives built by Inchicore railway works in 1929 and were the last locomotives designed by J. R. Bazin. The Class 710 consisted of ten 0-6-0 locomotives built by Inchicore railway works in 1934.

History

Class 700
The design was more traditional with a saturated Belpaire boiler that was unique to the 700 class. It was also fitted with slide valves as opposed to piston valves.  The tenders used initially were those reallocated from withdrawn 360 class 4-6-0.  A more modern feature was underslung springs.

Operationally the need for the class has subsequently been questioned and speculation has arisen that it was to use up surplus type 60 boilers.
This class seems to have compared poorly with the older 101 Class when especially when the latter were fitted with superheated boilers, possibly due to an inadequate heating surface leading to high coal and water consumption.

Class 710
They were more modern than the five Class 700 0-6-0 introduced in 1929 though being more modern with piston valves and a type Z superheatered boiler. They could be thought of as a tender version of the GSR Class 670 0-6-2T introduced in 1933 but with smaller wheels more suited to branch and goods work.  Whilst intended as a modern addition to the 101 class they seemed to gain a reputation as poor steamers and heavy on coal and water.  Following their introduction the GSR resumed rebuilding the 101 class with the Z-type superheated boiler

Model
There is a detailed O Gauge model of engine 710 in the Fry model railway collection.
