Frank Morse Button. Frank Morse Button (August 14, 1866 – August 3, 1938) was an American landscape architect, known for his impactful designs in the City of Coral Gables, Florida. He was born in Brandon, Vermont and attended the University of Vermont where he received a degree in civil engineering in 1887. Button was a part of the Army Corps of Engineers from 1889 to 1899, where he worked on various projects, including the 1893 Chicago Columbian Exposition where he was responsible for laying the pilings for the facsimile battleship Illinois. In 1903, he joined the landscape firm of Ossian Cole Simonds, working on projects such as the Charles Deering estate at Buena Vista and Lincoln Park in Chicago.

He was the first registered landscape architect in Florida and named a Fellow of the American Society of Landscape Architects in 1910.

After the death of his wife, Button and his daughter moved to Florida, where he was hired by Coral Gables founder George Merrick as the master planner for Coral Gables at a fee of $1 an acre, and completed the first comprehensive map of the city in July 1921. His design for the city included parkways, canals, gardens, fountains, and recreational facilities and incorporated the use of native plants alongside tropical and imported specimens.

Button also directed the landscaping of all the streets, plazas, parkways and parks in Coral Gables, and his close participation in field-work led to his untimely death in 1938 when he fell into the path of a truck while supervising the planting of Ficus trees in the median of Bird Road.

The Coral Gables Historic Preservation Board created a 2-sided historic bronze marker honoring Frank Button for his significant role in the creation of the City of Coral Gables. It was placed in Alhambra Plaza at the intersection of Alhambra Circle and Granada Boulevard and unveiled at the City's annual Arbor Day Celebration on April 29, 2016.

Pul Doda. Pul Doda is a small township located in Doda district of Jammu and Kashmir. It was once a bustling town until 2008, when it was submerged in the river Chenab due to the rise in water levels caused by the Baglihar Dam.

Etymology

The name "Pul Doda" is derived from the bridges that were built in the area.

History

The first bridge constructed here was the only way to cross the Chenab river and reach Doda city. In 1957, a suspension motorable bridge was built in Pul Doda after a lorry bridge was damaged. This bridge remained the only one connecting the NH1B (now NH244) with the city of Doda. Over the years, several more bridges were built in Pul Doda, including a concrete bridge in 1997 and the Ganpat Bridge in 2008, which is considered the highest road bridge in India. Despite the construction of several bridges, only a few remain today. The bridges in Pul Doda hold historical significance, as they were built during the time when Jammu and Kashmir was a princely state. They continue to serve as important infrastructure for the local community, providing a crucial connection between different parts of the region.

Sulfur dicyanide. Sulfur dicyanide is an inorganic compound with the formula S(CN)2.  A white, slightly unstable solid, the compound is mainly of theoretical and fundamental interest given its simplicity.  It is the first member of the dicyanosulfanes Sx(CN)2, which includes thiocyanogen ((SCN)2) and higher polysulfanes up to S4(CN)2.  According to X-ray crystallography, the molecule is planar, the SCN units are linear, with an S-C-S angle of 95.6°.

Sulfur dicyanide begins to sublime at 30-40 °C and melts at 60 °C.  Under an inert atmosphere, it slowly decomposes to a yellow polymer at room temperature with a rate increasing in temperature.  The compound is unstable in acid, disproportionating to thiocyanate, cyanate, hydrogen sulfate,and cyanide, and neutral moisture induces decomposition to thiocyanic and cyanic acids.  Stable solutions are possible in many organic solvents.

Sulfur dicyanide was first synthesized by Lassaigne in 1828 from silver cyanide and sulfur dichloride.  Subsequent developments include Linneman's discovery that the same product arose from silver thiocyanate and cyanogen iodide, and Söderbäck's extensive analysis of reactions between metal cyanides and sulfur halides.  Linneman also discovered that sulfur dicyanide reacts with ammonia à la Pinner to give an amidine without displacing the S–C linkage, although dimethylamine induces decomposition to dimethylcyanamide and dimethylammonium thiocyanate.

Sulfur dicyanide generally reacts with noble metals to give heteroleptic cyano-thiocyano complices, although in rare cases it can ligate without decomposition, e.g.:
Ir(CO)(PPh3)2Cl + NCSCN → Ir(CO)(CN)(SCN)(PPh3)2Cl
Ir(N2)(PPh3)2Cl + S(CN)2 → Ir(S(CN)2)(PPh3)2Cl

Sharjah Sustainable City. Sharjah Sustainable City is the first sustainably built city in Sharjah, United Arab Emirates. It currently spans 7.2 million square feet in Sharjah's Al Rahmaniya Area. The city was developed by Sharjah Investment and Development Authority (Shurooq) in partnership with Diamond Developers. It is divided into blocks of properties ranging from 2,035 square feet to 3,818 square feet, with a total of 1,250 sustainable properties.

The city is powered by renewable energy generated by rooftop solar panels and is constructed with sustainable materials. The designs are made to have low operating costs. It reuses 100% of its wastewater for landscape irrigation and maximizes recycling to divert waste from landfills. The city also produces chemical-free leafy greens and vegetables. With an emphasis on food security, the city hosts indoor farming facilities and partially solar-powered greenhouses that produce approximately 10,000 kg of chemical-free leafy greens and vegetables annually.

The city is managed by a team led by the chief executive officer, Yousif Ahmed Al-Mutawa.

History

The city was developed by Sharjah Investment and Development Authority (Shurooq) in partnership with Diamond Developers and is modelled after 'The Sustainable City' in Dubai. It aims to become a fully sustainable and functioning city.Sharjah Sustainable City, the first sustainable master-planned residential community developed by Sharjah Investment and Development Authority (Shurooq) in collaboration with Diamond Developers, has achieved remarkable success, with sales transaction values exceeding AED 2.5 billion across all four phases of the project.

Samrawit Fikru. Samrawit Fikru (Amharic: ሳምራዊት ፍቅሩ) is an Ethiopian computer scientist, entrepreneur, and businesswoman who is the founder and CEO of Hybrid Designs PLC, a software development company which produces the most popular ridesharing app in the country, RIDE.

Early life and education 

Fikru was born in Asella, Ethiopia. She received her diploma in software engineering from MicroLink Information Technology College in 2004. She graduated with a BSc in computer science from the HiLCoE School of Computer Science and Technology in 2006.

Career 

Fikru founded the software development company Hybrid Designs in 2014. The same year, Hybrid Designs released RIDE as an SMS-based ridesharing service. It was relaunched as a mobile app with a backing call center in July 2017. RIDE was inspired by the difficulty Fikru experienced trying to hire a taxi cab after late nights at work, and was partly inspired by the then existing ride sharing app, ZayRide. She also wanted to create a service to address the safety concerns felt by herself and others in trying to find a taxi, and developed RIDE to help address these gaps.

As of 2020, the app has tens of thousands of users and has been downloaded over 50,000 times. The development staff for the app is 90% female. Fikru aims to inspire other women with her work: "Women-owned business are growing in number; now we need more young girls to access the finances to make their creative ideas happen."

In 2022, Fikru released Sewasew, a streaming platform for Ethiopian music.

Honors and awards 

Fikru was recognized as one of the Rest of World's 100 Global Tech Changemakers
Fikru's success as a tech entrepreneur and her inspiration to young women were recognised by her inclusion on the BBC's 100 Women list in 2022.
