Samar-class offshore patrol vessel. Samar class of offshore patrol vessels are series of five ships built by Goa Shipyard Limited, Vasco da Gama, Goa for the Indian Coast Guard.

Design and description
The construction of vessels was ordered in April 1990 and these ships are half-sisters to seven  units in the Indian Navy. A total of twelve were originally planned and then cut to six. The vessels are intended for offshore patrol duties for the protection of oil platforms and the Indian exclusive economic zone.

The vessels in this class are  long with a beam of . They are powered by two Kirloskar-SEMT-Pielstick diesel engines () driving two propellers and have a range  at a cruising speed of . The Samar-class ships feature an Integrated Bridge System (IBS), Integrated Machinery Control System (IMCS), high power External Fire Fighting System, two Indian-built 30 mm gun mounts and one 76 mm OTO Melara dual-purpose gun. Besides, the ships are provided with a BEL-made onboard day/night infrared surveillance system to detect elusive targets which can evade radar detection due to their small radar cross-section (RCS) or higher sea state.

Capability
Each ship carries a single Dhruv Advanced Light Helicopter (ALH), with dedicated hangar and flight deck, and five high speed boats.
The vessels also have towing capacity for salvage and Inmarsat satellite communications. They have accommodation for a crew of 12 officers and 112 enlisted sailors. Additional accommodation has also been provided for passengers.

Operational history 
On 25 August 2024, Indian Coast Guard rescued 11 crew members from a sinking merchant vessel MV ITT Puma. The MV was travelling from Kolkata to Port Blair when it sank 90 nautical miles south of Sagar Island due to adverse weather and sea environment. The search and rescue operation was conducted in coordination by ICGS Amogh(an Aadesh-class patrol vessel) , ICGS Sarang and an ICG Dornier 228 aircraft.

Puck puzzle. The Puck puzzle (Hungarian: Kép Korong), also known as Picture Disc, is a combination puzzle invented in 1980 by Hungarian physicist András Végh. The disc shaped puzzle consists of 2 central pieces: the inner disc, and segments forming a ring around the inner disc. The number of segments is an even number, most commonly six, eight, or twelve. The outer ring can be rotated around the central disc, similar to a wheel being rotated around its axis. The two parts of the central disc can also be rotated, together with the attached ring.
With these operations, the combination of the parts can be changed. The goal of the game is to obtain a specific combination, such as forming a picture or ordering a sequence of numbers on the segments.

Navcam. Navcam, short for navigational camera, is a type of camera found on certain robotic rovers or spacecraft used for navigation without interfering with scientific instruments. Navcams typically take wide angle photographs that are used to plan the next moves of the vehicle or object tracking.

Overview
The Mars Curiosity rover has two pairs of black and white navigation cameras mounted on the mast to support ground navigation. The cameras have a 45 degree angle of view and use visible light to capture stereoscopic 3-D imagery. These cameras, like those on the Mars Pathfinder missions support use of the ICER image compression format.

European Space Agency Rosetta spacecraft used a single camera with 5 degree field of view and 12 bit 1024x1024px resolution allowing for visual tracking on each of spacecraft approaches to the asteroids and finally the comet.

James Ting. James Henry Ting Wei (丁謂, born 1951) is a Shanghai-born Chinese-Canadian former business executive who was once one of Hong Kong's most successful businessmen before being charged with illegal business practices.

Early years
Ting was born in Shanghai in 1951 and moved to Hong Kong in 1958, where he studied at Rosaryhill School from 1963. Ting moved to Australia and moved to Canada with his wife to study engineering at the University of Toronto. After graduation, Ting founded International Semi Tech Microsystems, a computer assembler, in Toronto in 1981.

Building the empire
With Semi-Tech Ting expanded beyond computer components to acquire various high-profile businesses like Singer Corporation, Sansui Electric, G.M. Pfaff and Akai. At its peak in 1997, Ting's business empire employed 100,000 people in 120 countries with sales of $5 billion. Before the empire collapsed in 1999, Ting sold them to Grande Holdings, which he founded in 1987.

Collapse and downfall
These businesses Ting was involved in and improper business practices brought down his empire, tarnished the businesses he led or acquired. Singer made a loss of $238 million in 1997, while Semi-Tech and Akai both went bankrupt in 2000.

Ting fled Canada to avoid investigation by Canadian and US authorities and eventually Hong Kong to Macau. He was forced to return to Hong Kong, but left for China to avoid being investigated by Hong Kong regulators from 2000 to 2003. He was arrested after flying back from Macau by helicopter in March 2003 and was then investigated by Hong Kong Police's Commercial Crimes Bureau. On 29 June 2005 he was convicted to two counts of false accounting relating to a fake HK$300 million stake in MicroMain Systems, and was sentenced to six years in prison. After serving only one year, Ting's conviction was overturned by Hong Kong's Court of Appeals and he escaped retrial in 2006. He escaped another retrial in November 2007.

Ting's whereabouts after his legal problems are unknown.

Diethylaniline. Diethylaniline is the organic compound with the molecular formula (C2H5)2NC6H5.  It is a colorless liquid but commercial samples are often yellow.  It is a precursor to several dyes and other commercial products.

Uses
Its condensation with half an equivalent of benzaldehyde gives brilliant green, an analogue of the very useful malachite green.  With formylbenzenedisulfonic acid it condenses to give Patent blue VE, and with hydroxybenzaldehyde followed by sulfonation one obtains Patent blue V. When treated with phosgene, one obtains Ethyl violet, an analogue of methyl violet.

In organic synthesis, the complex diethylaniline·borane (DEANB) is used as a reducing agent.

Diethylaniline and dimethylaniline are both used as acid-absorbing bases.  The advantage to the diethyl derivative is that   is non-hygroscopic, in contrast to .

Safety
Diethylaniline may be genotoxic because it has been found to increase the rate of sister chromatid exchange.

Hanriot 1909 monoplane. The Hanriot 1909 monoplane was an early French aircraft constructed by Rene Hanriot, a successful automobile racer.

Design

The Hanriot 1909 monoplane had an uncovered  rectangular-section wire-braced wooden fuselage with deeply cambered parallel-chord wings. The main undercarriage consisted of a pair of skids which carried a pair of independently sprung wheels mounted on a steel cross tube, the skids being carried on two pairs of struts which converged inwards, the aft pair being continued above the fuselage to form an inverted V cabane to which the wing bracing and warping wires were attached. The front struts terminated at the engine bearers, which were midway between the upper and lower longerons. Tail surfaces consisted of a tailplane and elevator mounted on top of the fuselage and a fixed fin mounted under the fuselage with the attached rudder underneath the horizontal tail surfaces. The aircraft was controlled with a pair of handwheels on either side of the cockpit operating wing warping and elevator, and foot-pedals operating the rudder.

Two examples were shown at the Paris Aero Salon in October 1909 in an unfinished condition. One was powered by a (37 kW (50 hp)  Buchet engine and the other by a 25 kW (35 hp) Hanriot engine.  One was successfully flown at Rheims in December 1909, first by Eugene Ruchonnet and afterwards by Rene Hanriot followed by his son Marcel, then aged 15.

The two aircraft displayed at the 1909 Paris exhibition were the only examples manufactured.  Flight refers to them as the Hanriot I (Hanriot engine) and Hanriot II (Buchet engine).  By the time that they were first flown  Hanriot and Ruchonnet had already started work on a series of closely related monoplane designs, which were exhibited at the Salon d'Automobiles, d'Aeronautique, du Cycles et des Sports,  which opened in Brussels on 16 January 1910.
