SEZ Corridor. The SEZ Corridor  is an emerging corridor implementing a number of Special Economic Zones (SEZs) along the Grand Southern Trunk Road (NH 45) in Chennai. Started with the establishment of the Madras Export Processing Zone in 1984 (converted to a SEZ in 2003), the SEZ corridor currently has 5 operational SEZs and over 10 approved projects in development. The GST Road is widely made use of for SEZ projects due to its connectivity with various means of transport by road, rail and air. This is evident by the presence of the Chennai International Airport, various railway stations parallel to the road, and also its connectivity to the complex road network of the National Highways Authority of India.

SEZs
A number of SEZ projects has emerged in this stretch, making it the SEZ corridor of Chennai. It includes MEPZ SEZ established in 1984, Mahindra World City, New Chennai, Shriram Properties's Gateway SEZ, Estancia SEZ and ETL Infrastructure.

It is also emerging as a major IT SEZ region with a number of huge investments by Infosys. Infosys has set up its largest development center in Mahindra SEZ while India Land Tech Park is developing a massive  SEZ which is estimated to have  office space for both IT and Electronics use. Shriram The Gateway SEZ, is an integrated township with IT/ITeS SEZ residential and mall, which is also home for IT majors like Accenture, ReDIM Information Systems and EISL is an IT/ITES SEZ by ETL Infrastructure at Chengalpattu on .

INS Taragiri (F41). INS Taragiri (F41) was a  of the Indian Navy. Taragiri was commissioned into the Navy on 16 May 1980 and was decommissioned on 27 June 2013 in Mumbai, after serving 33 years in the navy.

History 
INS Taragiri was the final ship of the Nilgiri class, and was named after a hill range in the Garhwal Himalaya. Cdr. Rahul Shankar was the 27th and last commanding officer of the frigate. Along with , she was significantly modified. A Westland Sea King anti-submarine helicopter, A244S 321 mm triple torpedo tubes and a twin-tube launcher for Bofors 375mm anti submarine rockets were added. Later, she was also fitted with advanced ship control systems for controlling unmanned aerial vehicles. These modifications gave the ship enhanced anti-submarine and network-centric warfare capabilities. She was operational under the Western Naval Fleet of the navy and performed surveillance missions when on blue water operations, and later performed coastal patrolling and anti-piracy operations.

John C. Boyle Dam. The John C. Boyle Dam was a hydroelectric dam located in southern Oregon, United States.  It was on the upper Klamath River, south (downstream) of Keno, and about  north of the California border. Originally developed and known as Big Bend, the John C. Boyle dam and powerhouse complex was re-dedicated to honor the pioneer hydroelectric engineer who was responsible for the design of
virtually all of the Klamath Hydroelectric Project.

The Boyle Diversion Dam included several sections (earth-fill, concrete gravity, intake and spillway) that combined to form an overall crest length of  with a height of . The concrete spillway portion contained three gates and formed the John C. Boyle Reservoir. Fish screens, fish ladder, and related features were also present at the site.

The dam produced power at peak times, meaning sometimes it produces electricity and returns water to the river; other times only a small amount of water is returned to the river. This causes a "bathtub" ring effect downstream of the plant's turbines.

The John C. Boyle Dam is one of four on the Klamath River that was removed under the Klamath Economic Restoration Act. As of February 2016, the states of Oregon and California, the dam owners, federal regulators and other parties reached an agreement to remove all four dams by the year 2020, pending approval by the Federal Energy Regulatory Commission (FERC). As of October 2020, negotiations stalled. As of February 25, 2022, the FERC released their final Environmental Impact Statement (EIS) on the dam's removal. The dam was removed in 2024. The social movement to Un-Dam the Klamath had been ongoing for 20 years.

It was named after John C. Boyle (1899–1979), who was vice president, general manager, and long-time chief engineer of the California Oregon Power Company (COPCO), a privately held utility that served southern Oregon and portions of northern California.

High-level verification. High-level verification (HLV), or electronic system-level (ESL) verification, is the task to verify ESL designs at high abstraction level, i.e., it is the task to verify a model that represents hardware above register-transfer level (RTL) abstract level. For high-level synthesis (HLS or C synthesis), HLV is to HLS as functional verification is to logic synthesis.

Electronic digital hardware design has evolved from low level abstraction at gate level to register transfer level (RTL), the abstraction level above RTL is commonly called high-level, ESL, or behavioral/algorithmic level.

In high-level synthesis, behavioral/algorithmic designs in ANSI C/C++/SystemC code is synthesized to RTL, which is then synthesized into gate level through logic synthesis. Functional verification is the task to make sure a design at RTL or gate level conforms to a specification. As logic synthesis matures, most functional verification is done at the higher abstraction, i.e. at RTL level, the correctness of logic synthesis tool in the translating process from RTL description to gate netlist is of less concern today.

High-level synthesis is still an emerging technology, so High-level verification today has two important areas under development
 to validate HLS is correct in the translation process, i.e. to validate the design before and after HLS are equivalent, typically through formal methods
 to verify a design in ANSI C/C++/SystemC code is conforming to a specification, typically through logic simulation.

Shonkinite. Shonkinite is an intrusive igneous rock found in few places in the world. It is unique in having low silica, feldspathoid minerals, and large blocky crystals of black augite. It makes up much of the hard dark grey rock comprising certain mountains and buttes in Montana that are remnants of laccoliths and stocks, such as the Highwood mountains.

Composition

Shonkinite is an intrusive igneous rock. More specifically, it is a mafic foidal (feldspathoid bearing) syenite, a holocrystalline (completely crystalline) intrusive rock which, , is composed of potassic feldspar (in the form of sanidine), with nepheline, augite, biotite, and olivine. Shonkinite is also used for mafic nepheline syenite with aegerine-augite as the pyroxene, and with the addition of plagioclase (andesine to labradorite). Nepheline in shonkinite from the  is largely altered to natrolite and stilbite.

The close view of the rocks in the Adel mountains show large glossy crystals of augite in a dark grey matrix made up of small crystals of augite and feldspar. This is unusual as augite is usually dull.

Formation 

In central Montana buttes of shonkinite are capped with white layers of syenite. There appear round globes of syenite at the boundary which suggest that the less dense syenite float up to the top of molten shonkinite as the mass cooled.

Occurrence 

The Adel Mountains Volcanic Field in north-central Montana
Mountain Pass, California.
India in the Salem Block in the Southern Granulite Terrane and the Elchuru alkaline complex in India 
Ontario, Canada
Timor, Indonesia

Etymology

The rock gets its name from the type locality at Shonkin Sag in the Highwood Mountains of north-central Montana.

Diethylaluminium chloride. Diethylaluminium chloride, abbreviated DEAC, is an organoaluminium compound. Although often given the chemical formula (C2H5)2AlCl, it exists as a dimer, [(C2H5)2AlCl]2 It is a precursor to Ziegler-Natta catalysts employed for the production of polyolefins. The compound is also a Lewis acid, useful in organic synthesis. The compound is a colorless waxy solid, but is usually handled as a solution in hydrocarbon solvents. It is highly reactive, even pyrophoric.

Structure and bonding
Compounds of the empirical formula AlR2Cl (R = alkyl, aryl) usually exist as dimers with the formula (R2Al)2(μ-Cl)2. The bridging ligands (indicated by "μ-") are halides, not the organic substituents.  The aluminium adopts a tetrahedral geometry.  Each Al(III) center follows the octet rule.  In contrast, triethylaluminium and trimethylaluminium feature bridging alkyl groups and these compounds violate the octet rule.

Production 
Diethylaluminium chloride can be produced from ethylaluminium sesquichloride, (C2H5)3Al2Cl3, by reduction with sodium:

2 (C2H5)3Al2Cl3 + 3 Na → 3 (C2H5)2AlCl + Al + 3 NaCl
It is also obtained from the reaction of triethylaluminium with hydrochloric acid:
(C2H5)3Al + HCl → (C2H5)2AlCl + C2H6
Reproportionation reactions can also be used:
2 (C2H5)3Al + AlCl3 → 3 (C2H5)2AlCl
(C2H5)3Al2Cl3 + (C2H5)3Al → 3 (C2H5)2AlCl

Uses 
Diethylaluminium chloride and other organoaluminium compounds are used in combination with transition metal compounds as Ziegler–Natta catalysts for the polymerization of various alkenes.

As a Lewis acid, diethylaluminium chloride also has uses in organic synthesis. For example, it is used to catalyze the Diels–Alder and ene reactions. Alternatively, it can react as a nucleophile or a proton scavenger.

Safety
Diethylaluminium chloride is not only flammable but pyrophoric.

Spectrum Aircraft. Spectrum Aircraft was a Canadian ultralight aircraft manufacturer that commenced operations in 1983 and went out of business in 1992. The company was known for its Beaver ultralight design, which remains in production by successor companies in the 21st century.

History

Sprectrum's first product was the RX-28 Beaver, a single-seat, high wing ultralight aircraft powered by a  Rotax 277 single cylinder, two stroke powerplant. It was introduced in 1983 and gained quick popularity in Canada and the USA. The following year the RX-28 was joined in production by the RX-35, which used the  Rotax 377 engine.

In 1986 the company started production of a two-seat version of the Beaver, designated the RX 550 and powered by a Rotax 503  engine. This model proved very popular as both a trainer and for private use and propelled the company into the forefront of ultralight aircraft production in North America.

In 1991 the company introduced the RX-650 Beaver, intending to market it in the then-newly introduced Canadian Advanced Ultra-light Aeroplane (AULA) category that allows passenger carrying. The aircraft proved to have structural issues that caused Transport Canada to remove it from the AULA list. The company went out of business in 1992, before rectifying the deficiencies in the RX-650's design.

Successors

Beaver RX Enterprises
The RX-550 design was acquired by a new company, Beaver RX Enterprises, who returned the aircraft to production. The company did not last long and soon went out of business.

Aircraft Sales and Parts
In 1995 Aircraft Sales and Parts (ASAP) of Vernon, British Columbia purchased the RX-550 tooling and redesigned the aircraft. The new version was designated the RX 550 Plus and remains in production in kit form. By the end of 2007 a total of 2000 RX 550s had been produced by all manufacturers.

In 2000 ASAP introduced a single seat version of the Beaver based on the RX-28, designated the Beaver SS (Single Seat). Powered by a  Rotax 447 engine and with a wing derived from the RX 550 Plus design, this aircraft remains in kit production.

Freedom Lite & Legend Lite
In 1996 a new company, Freedom Lite, introduced a redesigned version of the Beaver RX 650. This improved RX 650 incorporated 186 changes over the previous version and was designated the SS-11 Skywatch and the company placed the aircraft in the Canadian AULA category. Freedom Lite soon went out of business and the design was acquired by Legend Lite of New Hamburg, Ontario. This new company also closed its doors in the early 2000s.

Doctor Who and the Mines of Terror. Doctor Who and the Mines of Terror is a game for the Amstrad CPC, BBC Micro and Commodore 64. It was first released by Micro Power on the BBC Micro in 1985, and on the Amstrad CPC & C64 in 1986.

Gameplay

The game's play centres on the player's character of the Doctor (specifically his sixth incarnation), and his robotic programmable cat Splinx. The goal of the game is to halt the Master's production of Heatonite, retrieve stolen plans for the Time Lords, and return safely.

The game's screen always has the player in the centre, and depending on the direction of movement, the entire screen scrolls horizontally, vertically, or diagonally. The player can move freely, but can die in many ways: monster attack, robot attack, too great a fall, forced regeneration, lack of oxygen, and sharp spikes.

Enemies include patrolling robots that resemble the Daleks; however, the actual name and exact design of the Daleks was not used due to the rights to them being part owned by Terry Nation, creator of the Daleks.

Development and release
The game began life as a sequel to the hit BBC Micro game Castle Quest, and was adapted into a Doctor Who game mid-development.

As it was too large to fit into the standard memory of the BBC Micro, it came with its own ROM chip which had to be installed for the game to run in conjunction with game's main disk.

Reception 
Zzap!64's reviewers noted the game's similarity to Castle Quest.  They found that despite average graphics and weak sound, it was an enjoyable release thanks to the entertaining gameplay.  It was rated 86% overall.

ASM gave the game 4 out of 10, saying the game was trite.

Ceres (workstation). The Ceres Workstation was a workstation computer built by Niklaus Wirth's group at ETH Zurich in 1987. The central processing unit (CPU) is a National Semiconductor NS32000, and the operating system, named Oberon System is written fully in the object-oriented programming language Oberon. It is an early example of an operating system using basic object-oriented principles and garbage collection on the system level and a document centered approach for the user interface (UI), as envisaged later with OpenDoc. Ceres was a follow-up project to the Lilith workstation, based on AMD bit slicing technology and the programming language Modula-2.  

On the same hardware, Clemens Szyperski implemented as part of his Doctor of Philosophy (PhD) thesis an operating system named ETHOS, which takes full advantage of object-oriented technologies. A Usenet posting by Szyperski says that Oberon/F, which was later renamed to BlackBox Component Builder, incorporates  ETHOS ideas and principles.
