Indian Naval Ship (INS) Talwar is participating in Exercise Cutlass Express 2021, which commenced on July 26 along the East Coast of Africa, to improve combined maritime law enforcement capacity and increase interoperability between the regional navies. The exercise will conclude on August 6.
The exercise is an annual maritime exercise conducted to promote national and regional maritime security in East Africa and the Western Indian Ocean, an official statement from the Ministry of Defence said.
The 2021 edition of the exercise involves the participation of 12 Eastern African countries, US, UK, India and various international organisations, like International Maritime Organisation (IMO), United Nations Office on Drugs and Crime (UNODC), Interpol, EurEuropean Union Naval Forc (EUNAVFOR), Critical Maritime Routes Indian Ocean (CRIMARIO) and EUCAP Somalia.
As a part of the exercise, the Indian Navy, together with other partners, would undertake training of contingents from various participating countries in various fields across the spectrum of maritime security operations.

Mangroves are rare, spectacular and prolific ecosystems on the boundary between land and sea. These extra ordinary ecosystems contribute to the wellbeing, food security, and protection of coastal communities worldwide. They support a rich biodiversity and provide a valuable nursery habitat for fish and crustaceans. Mangroves also act as a form of natural coastal defense against storm surges, tsunamis, rising sea levels and erosion. Their soils are highly effective carbon sinks, sequestering vast amounts of carbon.
Yet mangroves are disappearing three to five times faster than overall global forest losses, with serious ecological and socio-economic impacts. Current estimates indicate that mangrove coverage has been divided by two in the past 40 years.
UNESCO is engaged deeply in supporting the conservation of mangroves, while advancing the sustainable development of their local communities. The inclusion of mangroves in Biosphere Reserves, World Heritage sites and UNESCO Global Geoparks contributes to improving the knowledge, management and conservation of mangrove ecosystems throughout the world.
The International Day for the Conservation of the Mangrove Ecosystem, adopted by the General Conference of UNESCO in 2015 and celebrated each year on 26 July, aims to raise awareness of the importance of mangrove ecosystems as “a unique, special and vulnerable ecosystem" and to promote solutions for their sustainable management, conservation and uses.

Kandla Special Economic Zone (KASEZ), the oldest export zone in the country, has become the “first green industrial city” in India to receive a platinum rating under IGBC Green Cities Rating for existing cities in the industrial cities category.
“We become the first green industrial city in India to receive platinum rating after a year-long rigorous audit and inspections conducted by IGBC. This has been possible because we have not only increased the green cover in KASEZ, but have managed to grow 68 species of trees and attract 28 varieties of birds — which were also audited and counted — on a piece of land that was once a salt pan with almost no vegetation,”.
Compared to the 25,000 trees in KASEZ in 2019, the 1000-odd acres has 3.5 lakh trees. Most of these trees have been planted post 2019, using the Miyawaki forestation method.

Three new fluorinated bis(pyrazoles), namely: 1,4-bis(1H-pyrazol-4-ylethynyl)-2-fluorobenzene (H2BPEFB), 1,4-bis(1H-pyrazol-4-ylethynyl)-2,3-difluorobenzene (H2BPEF2B) and 1,4-bis(1H-pyrazol-4-ylethynyl)-tetrafluorobenzene (H2BPEF4B), have been synthesized taking advantage of Sonogashira coupling reactions, and characterized as per their crystal and molecular structure, spectroscopic and dielectric properties, and hydrophobicity.
In the crystal structures, the three molecules, whose deviation from planarity increases on increasing the fluorination degree, interact by means of hydrogen bonds, forming 2D supramolecular layers. Notably, the absorption and fluorescence emission properties are only slightly affected by the fluorination degree in both the solid state and solution.
Furthermore, the spectral line-shapes are weakly dependent on the environment when dissolved in a number of solvents of different polarity and hydrogen-bonding affinity.
On the other hand, the dielectric constant monotonically increases on increasing the number of fluorine atoms.

At 13 years old, skateboarder MomijiNishiya of Japan just became one of the youngest gold medal winners ever at the Olympic Games. The girls standing by her side on the podium? Also teenagers.
Nishiya took home the gold Monday in the women's street competition — which debuted in Tokyo for the very first time. It sealed her nation's fate as the current dominating force in skateboarding, following a win by YutoHorigome in the men's competition the day prior.
