Hermes (missile). Hermes () is a family of modularly designed guided missiles developed in Russia by the KBP Instrument Design Bureau.

The Hermes missile can be used from air, ground or naval launchers.

Development
Development of the Hermes by the KBP Instrument Design Bureau started in the 1990s. The missile bears a striking resemblance to the 57E6 used by the Pantsir missile system, and it is probably a derivative of this model. The Hermes-A variant was trialed in 2003. The series production of the Hermes was meant to start in 2011-2012, but this did not happen, as the development process was stopped for several years. In 2016, it was announced that the Hermes missile would be tested in live conditions in Syria. However, nothing indicates that this actually happened. But in the late 2010s, a series of announcements signaled a renewed interest in the missile, following experience from the Russian military intervention in the Syrian civil war showing the need for more high-precision armaments.

Description
The Hermes system features a multistage rocket missile with a high-powered booster. Two booster diameters are available, 170 and 210 mm. It uses inertial and/or radio-command guidance for the cruise phase, and semi-active laser guidance for the terminal phase. Radar and infrared homing are also talked about. The Hermes is designed to engage a great variety of targets, including armoured vehicles, fortifications of various types, small naval surface targets, artillery positions, slow-flying air targets, and others. It can be fired single or in volleys at ranges of up to 100 km and can track and destroy over-the-horizon targets.

Characteristics
 Warhead: 27.5 kg
 Explosive: 13 kg
 Guidance: Inertial and/or radio-command guidance (cruise phase), semi-active laser homing (terminal). Possible infrared and radar homing

Variants
 Hermes-A: Air-launched version. To be used by the Kamov Ka-52 (up to 16 launchers) and possibly the Sukhoi Su-25. Range between 15 and 20 km.
 Hermes-K: Naval version. Two types of supports are available: a simpler support with four launchers for lighter naval units, and a modified version of the AK-306 CIWS with four launchers for heavier vessels. The Hermes-K's range can be increased up to 100 km with the use of the 210 mm booster.
 Hermes-S: Land vehicle version. Uses a Kamaz truck chassis, transporting up to 24 missiles. Versions with and without a guidance system for the missiles have been shown in designer drawings. Moreover, a fire-control vehicle with a mast-mounted radar or opto-electronic detection system has also been shown. A coastal defence version is also possible. The Hermes-S's range can be increased to 100 km with the use of the 210 mm booster.

Rockefeller Differential Analyzer. Designed by Vannevar Bush after he became director of the Carnegie Institution for Science in Washington DC, the Rockefeller Differential Analyzer (RDA) was an all-electronic version of the Differential Analyzer, which Bush had built at the Massachusetts Institute of Technology between 1928 and 1931.

The RDA was operational in 1942, a year after the Zuse Z3. It was equipped with 2000 vacuum tubes, weight 100 tons, used 200 miles of wire, 150 motors and thousand of relays. According to historian Robin Boast, "the RDA (Rockefeller Differential Analyzer) was revolutionary, and later was considered to be one of the most important calculating machines of the Second World War."

Chernobylite. Chernobylite is a technogenic compound, a crystalline zirconium silicate with a high (up to 10%) content of uranium as a solid solution. 

It was discovered in the corium produced in the Chernobyl disaster, a lava-like glassy material formed in the nuclear meltdown of reactor core 4. 
Chernobylite is highly radioactive due to its high uranium content and contamination by fission products.

3237. 3237 is a preserved former New South Wales Government Railways C32 class steam locomotive. Built in 1893 by Beyer, Peacock & Company, England, it is preserved by the Lachlan Valley Railway.

In service
3237 was built by Beyer, Peacock & Company, Manchester in 1892 and entered service on 26 February 1893. Originally numbered P508, it became 3237 in the 1924 renumbering scheme. It worked mainline runs around New South Wales, while its original use was as a passenger express locomotive, it was also used for light freight. For the last part of its working career 3237 was based at Dubbo locomotive depot, 3237's last duties were to work reclamation trains and as a yard shunter in Dubbo.  It was withdrawn on 3 November 1971, when it was sent light engine from Dubbo to Enfield Locomotive Depot for storage. In its 78 years of revenue service, from 26 February 1892 to 1 November 1971, 3237 ran a total of 2,225,224 miles.

Preservation
3237 was stored at Enfield Locomotive Depot for three years before being moved twice. The first move was to Parkes, on 22 October 1974, in a three loco light engine movement, comprising 6042 (in steam) + 3237 (dead) + 3026T (in steam), as exhibits for the Lachlan Vintage Village at Forbes. It was later sold to the Lachlan Valley Railway (LVR) and moved to Cowra.

3237 was dismantled during the 1980s for a lengthy overhaul which included a new front tube-plate. The overhaul was completed with 3237's returned to service in 2006. During a north coast tour in 2012 the locomotive sustained a mechanical issue and had to be taken out of service. It was repaired in Taree. Ten months later 3237 re-entered service for the LVR on the weekend of 11 & 12 May 2013 on shuttles for Taree Rail Centenary.

Minor running repairs commenced January 2014 with 3237 returning to service in mid 2014. Through the end of 2014, 3237 partnered up with 5917 with successful running weekends at Richmond, Valley Heights and a trip to Cootamundra.

After a tour in 2016 it received some repairs at Cootamundra where it was then transferred to Goulburn Roundhouse for a major overhaul by LVR volunteers funded partly by a Transport Heritage NSW grant program. This overhaul also included a Waugh grate conversion.

In September 2019 the locomotive returned to service on the annual LVR Richmond Steam Shuttles

Diamond grinding cup wheel. A diamond grinding cup wheel is a metal-bonded diamond tool with diamond segments welded or cold-pressed on a steel (or other metal, such as aluminum) wheel body, which usually looks like a cup. Diamond grinding cup wheels are usually mounted on concrete grinders to grind abrasive building materials like concrete, granite and marble.

Use
There are various styles and specifications of diamond grinding cup wheels to fit various application requirements. The ones with many big diamond segments can undertake heavy workloads, for example, grinding concrete and stone, while those with small or sparse diamond segments are normally used for fast removal of paints, wallpapers, glues, epoxy and other surface coatings.

Just like other metal-bonded diamond tools, the diamond segments on diamond grinding cup wheels can have different bonds, different diamond grits, different diamond quality and different diamond concentrations to fit different uses. For example, if the material to be ground is hard, the bond should be softer, and if the material is relatively soft, the bond should be harder.

Diamond grinding cup wheels are used in different-roughness grindings. For coarse grinding, the bond should be softer and the diamonds' quality should be higher, because in this case the diamonds become blunt more easily. The diamond grit should be bigger, normally from 35 grit to 50 grit. For this is coarse grinding and big grit can improve working efficiency. The diamond concentration can be lower.

For fine grinding (sometimes  called "polishing"), the bond should be harder and the diamonds' quality can be lower, as in this case the diamonds can last longer and a hard bond can also help the precision of the process. The diamond grit is normally between 80 grit and 120 grit, depending on the grinding requirements. The diamond concentration should be higher.

After being ground, the material can be further polished with resin-bonded diamond polishing pads of different diamond grits.

Manufacturing methods
There are two common methods to manufacture diamond grinding cup wheels: hot pressing and cold pressing.

The hot pressing method is to directly sinter the diamond segments in molds under a certain pressure in the dedicated sintering press machine, and then fix or connect the diamond segments onto the grinding wheel’s body via high-frequency welding, laser welding or mechanical mosaic method.

The cold pressing method is to first press the working layer (containing diamonds) and the transitive layer (not containing diamonds) of the diamond segments to their forms directly on the grinding wheel's body, and let the segments connect with the wheel's body via teeth, slots or other manners. Then, put the grinding wheels into sintering furnaces to sinter without press.

Continuous adsorption-regeneration. Electrochemical regeneration of activated carbon adsorbents such as granular activated carbon present an alternative to thermal regeneration or land filling at the end of useful adsorbent life. Continuous adsorption-electrochemical regeneration encompasses the adsorption and regeneration steps, typically separated in the bulk of industrial processes due to long adsorption equilibrium times (ranging from hours to months), into one continuous system. This is possible using a non-porous, electrically conducting carbon derivative called Nyex. The non-porosity of Nyex allows it to achieve its full adsorptive capacity within a few minutes and its electrical conductivity allows it to form part of the electrode in an electrochemical cell. As a result of its properties Nyex can undergo quick adsorption and fast electrochemical regeneration in a combined adsorption-electrochemical regeneration cell achieving 100% regeneration efficiency.

Continuous adsorption-regeneration cell
The adsorption regeneration process is divided into three key elements which occur in different parts of the cell. All three occur continuously and simultaneously, with parameters such as charge passed, rate of effluent in/outflow and air inlet rate varied according to pollutant type and concentration.

Pollutant contacting and adsorption
Polluted effluent is added into the bottom of the cell and mixed with the adsorbent in the adsorption zone 1.1 where adsorption of the pollutants onto the surface of the adsorbent occurs. Mixing between the adsorbent and the polluted effluent is promoted by air spargers at the base of the cell which also facilitate the migration of the adsorbent upwards and into the cell's sedimentation zone.

Adsorbent-treated effluent separation
The adsorbent is separated from the now treated effluent in the sedimentation zone where the density of the adsorbent allows separation by gravitational sedimentation. The treated effluent is allowed to overflow out of the cell.

Adsorbent electrochemical regeneration
The adsorbent, loaded with adsorbed pollutant on its surface sediments and forms a bed in the regeneration zone in the cell. The mass of the Nyex causes the bed to travel down the regeneration column slowly and eventually pass back into the cell. During the journey down the regeneration column, a DC current is passed across the electrochemical cell of which the adsorbent forms the anode. The applied current causes the pollutants adsorbed on the surface of the Nyex to be electrochemically oxidised regenerating the adsorbent surface restoring its full adsorptive capacity completing the adsorption-regeneration cycle.

Applications
This technology is currently being incorporated into a variety of industries for applications in effluent treatment areas such as:
 Groundwater remediation
 Volatile Organic Compound Removal
 Dye-house Effluent De-Colourisation
 Electrochemical Disinfection

Military Free Fall Parachute System. The RA-1 Military Free-Fall Advanced Ram-Air Parachute System (MFF ARAPS) provides a multi-mission, high-altitude parachute delivery system that allows personnel to exit at altitudes between 3,500 feet and 35,000 feet. The parachute, which replaces the current MC-4 parachute, supports a total jumper weight of 450 pounds. It also provides non-MFF personnel with a ram-air parachute that is static-line deployed.

The ARAPS’ three accessory systems are at different stages of the acquisition process:
 The Electronic Automatic Activation Device (EAAD) is used with current and next-generation parachute systems, replacing the Automatic Ripcord Release. EAAD provides a simpler and more reliable method of activation in the event the parachutist is unable to deploy the parachute at the appropriate altitude. The EAAD activates and cuts the reserve parachute closing loops if the jumper is falling at 78 mph or faster at the minimum deployment altitude.
 The Navigation Aid (NAVAID) will provide in-flight navigation and mission planning capability, allowing parachutists under canopy to locate themselves and the intended drop zone easily. The system uses a GPS that integrates with the Mission Planner of the Joint Precision Airdrop System (MP JPADS), ensuring more accurate canopy flight and drop zone landings.
 The Parachutist Oxygen Mask (POM) will provide supplemental oxygen at 13,000 feet and higher and will be easier to use and maintain than the current MBU-12P mask. The POM will not interfere with the parachutist’s vision or range of motion.

State Highway 74 (Kerala). State Highway 74 (SH 74) is a State Highway in Kerala, India that starts in Vazhakode and ends in Alathur. The highway is 33.69 km long. The road connects important towns Chelakkara and Pazhayannur

This road from Vazhakkodu to Plazhy of 22.7km was selected to be re-tarred using climate resilient materials under the Rebuild Kerala Initiative for 105.4 crore. EKK Infrastructure Limited was given the tender and work started in 25.10.2021 and work is supposed to be completed by 25.04.2023(18 months construction time). And the contractor will be responsible for all maintenance for next 5 years. 

After 12 months of construction, local politicians said only 40% of the project is complete and that they don't think it will complete within the stipulated time of 18 months. They claim the road work is making life of the commuters difficult.

Some construction material was stolen, and the culprits arrested by the police during the construction of this road.
