Denel DMG-5. The Denel DMG-5 is a general-purpose machine gun designed and manufactured by Denel Land Systems of South Africa.

Design 
Denel Land Systems unveiled the lightest 7.62×51mm NATO general- purpose machine gun (GPMG) at the Africa Aerospace and Defence 2016. The new weapon, designated the Denel DMG-5, currently weighs 8.4 kg, 20% lighter compared to the company’s current production GPMG, the Denel SS-77, weighing 10.3 kg. This development challenge was given to three young engineers to refine the uniquely South African designed Denel SS-77 that was developed in 1977 by Richard Joseph Smith and Lazlo Soregi. The three young mechanical engineering graduates, Dakalo Nekhumbe, Phindile Mashaba and Marumo Talane, are all products of the Denel Engineering Academy.

The DMG-5 has an effective range of 1,500 m. It has a firing rate of 700 rounds per minute to 900 rounds per minute. It is gas-operated, with a side locking system. As with all GPMGs, it is fed with continuous belts of ammunition. Nominal muzzle velocity is 830 m/sec.  It can fire up to 400 rounds before the barrel needs to be cooled or replaced. With a long collapsible stock, it is 1.135 m long and, with a short collapsible stock, it is 1.055 m long.

The DMG-5 is chambered for 7.62×51mm NATO but could be made in 5.56×45mm NATO. It is slightly shorter than the SS-77. 

The DMG-5 differs from the SS-77 in most areas, except the operating system. The barrel is fluted to lighten it. The Feed Cover is equipped with a top mounted full length Picatinny rail to accommodate different optical day or night sights. Backup iron sights can be provided. The front grip is equipped with three Picatinny rails to attach accessories like flashlights, laser pointers, etcetera. A removable front pistol grip can be fitted on the front Picatinny rail and can be adjusted to suit the operator’s personal requirements. A retractable bipod can be mounted on the same Picatinny rail.

DMG-5 CX 
The DMG-5 CX is a longer heavy-barrelled version with spade grips for use in remotely controlled weapon stations, as a coaxial weapon on armoured vehicles, or flexible mounts on vehicles.

Variants

Time to value. Time to value (TTV) is a measure of the length of time necessary to undertake a project and realize the benefits of the solution. The concept is used to help decision makers evaluate the proposed benefit of an investment in time and/or money. It is a similar concept to return on investment (ROI), but instead of realizing the financial success of an investment, it implies achieving the effectiveness of an investment. This is applied mostly to added technology—data center hardware, network infrastructure, system security, etc. whereby the promised improvement becomes measurable. It can even be argued that in cases such as data security, TTV is more important than ROI since the security may only have financial benefits in banking and commercial industries, but has value in the protection of personal and/or corporate data—in every industry.

Limitation 
While the concept is easy to understand and explain to management or investors, one problem is that "completion", "benefit", and "value" are not as easy to define, can change over time, and the technology may even obsolesce before the installation is completed.

EM Solutions. EM Solutions Pty Ltd is a satellite communications component company based in Brisbane, Queensland, Australia. Founded in 1998, it is involved in the research, design, and production of differentiated microwave and radiofrequency products and systems for satellite and broadband communications.

The firm provides components for both commercial and military customers with its subsidiary, EMClarity, specialising in the broadcast industry. It has partnered with the Defence Science and Technology Group (DSTO), the Commonwealth Scientific and Industrial Research Organisation (CSIRO), and the University of Queensland.

History 
EM Solutions emerged as a successor to the founders' original company, Mitec Limited, in 1998. Founded in 1984 through the commercialization of the University of Queensland’s Microwave Technology Development Centre, Mitec produced communications products still in use today at companies including Optus and Telstra.

After Mitec's acquisition by Codan Pty Ltd for $30 million in 1998, EM Solutions was founded by Peter Bradley and Dr John Ness. It was acquired by the Australian company Electro Optic Systems (EOS) in October 2019.

In January 2025, it was announced that Cohort had completed its purchase of the company.

Products 
EM Solutions initially began developing solid-state power amplifiers, filters, and oscillators, before producing high-speed receivers and transmitters for radios. In 2008, EM Solutions launched its initial foray into SATCOM On-The-Move (SOTM) terminals after being granted sponsorship from the Australian Defence Force to develop a land-mobile Ka-band terminal.

In 2016, subsidiary EMClarity produced the world’s lowest latency 5 Gbit/s, E-band (70 to 80Ghz) microwave radio, the E10G. Now used to connect servers from the New York Stock Exchange (NYSE) to those of Nasdaq Stock Market, this product was created in response to industry requests for lower latency communications networks to equal the speed of computer processing platforms utilized to facilitate financial trades.

EM Solutions was commissioned by a United States government agency to supply E-band radios for ship-to-shore communication. Employing the steerable gimbal systems used in the company’s SATCOM On-The-Move terminals, the radios achieve the longest range and highest data rate of any commercial wireless system at 10 Gbit/s and 20 km, respectively.

In 2015, EM Solutions partnered with leading satellite telecommunications company, Inmarsat, to produce the first dual X- and Ka-bands terminal with universal (land or sea) capability. These terminals have been installed in the Australian Border Force's and the Royal Australian Navy’s Cape Class patrol boats, providing broadband access to crews of these vessels for the first time.

Ronald Martin Wilson. Ronald Martin Wilson (1886–1967) was an architect and engineer in Brisbane, Queensland, Australia. A number of his works are heritage-listed.

Early life 
Ronald Martin Wilson was born 14 July 1886 in Yeronga in Brisbane, the son of architect Alexander Brown Wilson. He attended the Brisbane Normal School and the Brisbane Grammar School. He worked in his father's architecture firm as an assistant while completing a degree in engineering at the University of Queensland.

Engineering 
The first meeting of the Greater Brisbane Council in March 1925 established  Cross River Commission to establish what bridges were needed for Brisbane. There were three members: chairman Roger Hawken, Professor of Engineering at the University of Queensland, William Muir Nelson and Wilson. Their report showed 11 proposed river crossings, and considered costs and savings made due to the reduction in haulage costs etc, and the need for a railway bridge was also discussed. Their report ultimately led to the construction of the William Jolly Bridge and the Story Bridge, but their proposal for a bridge at New Farm has yet to be realised.

Architectural works
Notable works by Wilson include:
 Cliffside Apartments in Kangaroo Point, listed on the Queensland Heritage Register
 St Lucia Presbyterian Church listed on the Brisbane Heritage Register
 conversion of a private home in Chelmer into a World War II convalescent hospital, The Lady Wilson Red Cross Convalescent Home, later the Chelmer Police College, listed on the Queensland Heritage Register
 St George's Greek Orthodox Church, South Brisbane, circa 1958, listed on the Brisbane Heritage Register

Later life 
Wilson died on 19 July 1967 at St Lucia. He was cremated.

Legacy 
The Wilson family of architects have contributed to Brisbane architectural practice for over 130 years through four generations: Alexander Brown Wilson, Ronald Martin Wilson, Blair Wilson and Hamilton Wilson. Since 2014, the practice is known as Wilson Architects.

SS T. A. Johnston. SS T. A. Johnston was a Liberty ship built in the United States during World War II. She was named after T. A. Johnston.

Construction
T. A. Johnston was initially laid down on 22 April 1944, under a Maritime Commission (MARCOM) contract, MC hull 2304, by J.A. Jones Construction, Panama City, Florida.  A fire on the slip way warped the original hull and it had to be scrapped. A new hull was laid down on 14 November 1944, and would go on to set a shipyard record of 29 days on the way when she was launched on 13 December 1944.

History
She was allocated to J.H. Winchester & Company, Inc., on 28 December 1944. On 7 January 1947, she was laid up in the National Defense Reserve Fleet, in the Hudson River Group. On 19 July 1955, she was withdrawn from the fleet to be loaded with grain as part of the "Grain Program 1955". She returned to the fleet on 4 August 1955, full of grain. On 22 April 1956, she was withdrawn to unload, she returned empty on 28 April 1956. On 4 August 1956, she was withdrawn for the last time to be loaded with grain, she returned full on 25 August 1956. She was withdrawn on May 18 1963, to be emptied and returned 25 May 1963. On 10 July 1970, she was sold, along with one other ship, for $80,323.08 to Union Minerals and Alloys Corporation, to be scrapped. She was removed from the fleet on 6 October 1970.

Ramsdellite. Ramsdellite (Mn4+O2) is an orthorhombic manganese dioxide mineral. It is relatively uncommon, and is usually found in deposits containing other manganese oxide crystals.

Name

Ramsdellite is named after the American mineralogist, Lewis Stephen Ramsdell (1895–1975).
Ramsdell spent almost all his career at the University of Michigan as a professional mineralogist.
Ramsdellite was one of the new phases he first recognized in the "black manganese oxide" minerals.
It was later named in his honour by Michael Fleischer and W. E. Richmond, who fully described the mineral in 1943.
The mineral is also called Groutellite.

Chemistry and crystallography

The chemical formula for Ramsdellite is MnO2. 
The empirical formula is Mn4+O2.
Ramsdellite has the same chemistry as the more common pyrolusite, but is orthorhombic where pyrolusite is tetragonal.
Ramsdellite belongs to the Orthorhombic crystal system and Dipyramidal crystal class.
Properties:

Classification

The Dana classification is 4.4.7.1 (simple oxides: AX2).
The Hey's CIM Ref is 7.18.8 (Oxides and Hydroxides, Oxides of Mn).
The Nickel–Strunz classification is 04.DB.15a, since the metal:oxygen ratio is around 1:2 and the mineral has medium-sized cations; chains of edge-sharing octahedra.
Other elements in the Ramsdellite / 04.DB.15 group are Paramontroseite: V4+O2 (15a), Akhtenskite: ε-Mn4+O2 (15b) and Nsutite: (Mn4+,Mn2+)(O,OH)2 (15c).

Distribution

Ramsdellite is formed by oxidization of weathered manganese minerals such as manganite, and is often found in deposits containing various other manganese oxides.
The mineral is relatively rare. 
The type locality, the place where Ramsdellite was first identified, is the Lake Valley district in Sierra County, New Mexico, US.
Other locations in the USA where well-characterized samples of Ramsdellite have been found are Artillery Mountains, Arizona; Mistake mine, Yavapai County, Arizona; Idarado mine, near Telluride, Colorado; and Monroe-Tener mine, near Chisholm, Minnesota.

Good samples have been found in Canada along the East River in Pictou County, Nova Scotia; in Mexico in Los Gavilanes, Baja California; In India in Dongari Buzurg, Bhandara, Maharashtra; in Australia in the Iron Monarch quarry, Iron Knob, South Australia; in Japan in the Otoshibetsu and Tanno mines, Hokkaido; in the Czech Republic at Horní Blatná; in Germany at Bütten-Adenstadt, Lower Saxony and Clara Mine, near Oberwolfach, Black Forest; in Egypt at Gebel To Yu, Yoider, and Um Bogna; and in South Africa at Hotazel, near Kuruman, Northern Cape.
Ramsdellite is found in the manganese deposits near Moanda, Haut-Ogooué Province, Gabon, mined by the Compagnie minière de l'Ogooué.
These deposits were formed by supergene enrichment of Precambrian sediments.
