Arganzuela Footbridge. The Arganzuela Footbridge (Spanish: puente or pasarela de Arganzuela, formally puente monumental de Arganzuela, also puente de Perrault) is a pedestrian bridge in Madrid, Spain.

History and description 
It partially occupies the land released by the burying of the M-30. Designed by Dominique Perrault, it cost about €13.6M.

Building works started in February 2010. The footbridge actually consists of two separate metal cones, one passing over the Madrid Río park while the other crosses over the Manzanares, nearly meeting at an elevated middle point serving as lookout of the Madrid Río park. The combined structure is 278 m long. Perrault employs plate rolling for the curved steel plates along the bridge span.

It was opened on 24 March 2011, although initially only for diurnal usage.

Open Service Mesh. Open Service Mesh (OSM) was a free and open source cloud native service mesh developed by Microsoft that ran on Kubernetes.

Overview
OSM was written in the Go programming language and designed to be a reference implementation of the Service Mesh Interface (SMI) specification, a standard interface for service meshes on Kubernetes. The software was based on the Envoy proxy server and allowed users to uniformly manage, secure, and get out-of-the-box observability features for highly dynamic microservice environments.

The source code is licensed under MIT License and available on GitHub. Microsoft donated OSM to the Cloud Native Computing Foundation to ensure that it is community-led and has open governance. On May 4, 2023, the project announced it would be archived, ending CNCF investment in the project so that its contributors could focus on Istio.

Poprad (self-propelled anti-aircraft missile system). The SPZR Poprad (pol. Samobieżny Przeciwlotniczy Zestaw Rakietowy) is a very short range air defense (VSHORAD)  self-propelled anti-aircraft missile system, produced by PIT-Radwar S.A.

Description 
The basic functions of the SPZR Poprad are realized by an integrated tracking and targeting head with highly dynamic and accurate drives. A set of electro-optics sensors (thermal imaging camera, daylight camera and laser rangefinder) works with the automatic target tracking system. The indication of targets is carried out via data transmitted via a digital channel from the automated air defense control system or is carried out autonomously. The kit includes a fire control computer, a navigation system and an IFF system. SPZR Poprad has been equipped with an inertial and satellite navigation system, thanks to which, after taking a fire position, the operator can immediately transfer the position of the set and the readiness status to the command system. The set is mounted as standard on the AMZ Żubr-P chassis produced by AMZ-Kutno. The design of the Poprad set minimizes the time needed to move from the transport position, in which the warhead is lowered and covered with roof covers, to the combat position.

The Poprad set can operate as part of the classic air defense system or independently. If the set operates in the anti-aircraft defense control system (it has communication with it), it receives the indicated targets and the command to open fire from there. Information about the radiolocation situation is transmitted to the Poprad system thanks to the VHF radio station or via wire communication. SPZR Poprad uses ZDPSR "Soła" radar stations, which indicate targets for the Poprad set batteries.

System application 
The Poprad self-propelled anti-aircraft missile system is designed to detect, recognize and destroy air targets at close ranges and low altitudes using short-range homing missiles. The set can be used to protect columns of troops, parking places, command posts and groupings, as well as airports, ports, industrial plants, communication junctions, etc. against air strikes.

Users 

According to the contract for the supply of Poprad anti-aircraft systems signed in December 2015, by 2021 the Polish Army is to receive a total of 79 of these sets, including 77 newly manufactured and 2 adapted from the implementation batch). Their deliveries started in 2018.

Apart from Poland, Poprad launchers were bought by Indonesian Army, as a part of export VSHORAD system Kobra, consisting of four Poprad launchers, two command vehicles, mobile MMSR radar and twelve towed AA guns with Grom launchers ZUR-23-2KG-I. All components are mounted upon lengthened 6×6 Land Rover Defender chassis (Polish modification Huzar). The system was delivered in 2007 and was designated locally as Aster (not to confuse with Aster missiles). In 2006 Indonesia ordered the second such system, delivered in 2010.

Cairns A. The Cairns A was a low wing, two tandem seat monoplane with a metal structure and stressed metal skin. It first flew late in 1931 with a  engine but was later fitted with more powerful engines including a  radial.

Design and development

The 1930s all metal, stressed skin Cairns A was unusual in a period when many light aircraft had wooden wing structures and most were fabric covered. Cairns had gained experience of metal aircraft structures when building the smaller, somewhat similar Cairns Clark Robinson Special in 1928. The Cairns A's construction details were sufficiently novel to attract the attention of the U.S. Navy Department and delay their release. In particular, the Naval Aircraft Factory Physical Laboratory undertook extensive tests of the monocoque fuselage.

Construction apart, the Cairns A was a conventional cantilever low wing monoplane. The wings, trapezoidal in plan with only slight taper out to blunted tips, carried short ailerons.

The first example flew in April 1930 and was powered by a Cairns G, a licence-built, four cylinder,  Gipsy I air-cooled upright inline engine. Its engine determined its  AG-4 sub-type designation. Cairns Aircraft intended to show that their fuselage could accept higher powers and this first prototype was later fitted with a radial engine of over twice the power of the Gipsy, a six cylinder,  Curtiss Challenger, becoming the AC-6. The AW-5, with a lower-powered, five cylinder,  Wright J-6 radial, was also tested but it is not known if it was a different airframe. Three were expected to be flying in January 1932 but photographic or other evidence is lacking for more than one.

Behind the engine the Model A seated two in separate cockpits, with the passenger or pupil at about one-third chord and the pilot at the trailing edge. The cantilever, trapezoidal tailplane was mounted near mid-fuselage and bore straight-tapered elevators. The largely rounded vertical tail included an unbalanced rudder.

The Model A's landing gear was fixed, with a track of . The legs were wing-mounted and enclosed in strongly-tapered, trouser type fairings, with the wheels in spats. There was a tailskid at the rear.

Variants

Cairns AG-4 Four cylinder,  Gipsy I upright inline engine.
Cairns AW-5 Five cylinder,  Wright J-6 radial.
Cairns AC-6 Six cylinder,  Curtiss Challenger radial.

Multi-role Electronically Scanned Array. The Multi-role Electronically Scanned Array (MESA) is an active electronically scanned array surveillance radar system for the Boeing E-7 Wedgetail airborne early warning and control aircraft. The radar is produced by Northrop Grumman.

Design and development

In the 1990s, Australia recognized a need for an airborne early warning and control (AEW&C) aircraft. In 1996, Australia issued a request for proposal (RFP) for the aircraft for the RAAF under Project Wedgetail, referring to the Wedge-tailed eagle. In 1999, Australia awarded Boeing Integrated Defense Systems a contract to supply four AEW&C aircraft with options for three additional aircraft.

The L band (1 to 2 GHz) electronically scanned AEW and surveillance radar is located on a dorsal fin on top of the fuselage, dubbed the "top hat", and is designed for minimal aerodynamic effect. The radar is capable of simultaneous air and sea search, fighter control and area search, with a maximum range of over 600 km (look-up mode). When operating in look-down mode against fighter-sized target, the maximum range is in excess of 370 km. When used against maritime targets, the maximum range is over 240 km for frigate-sized targets. MESA is capable of simultaneously tracking 180 targets and conducting 24 intercepts. In addition, the radar antenna array is also doubled as an ELINT array, with a maximum range of over 850 km at  altitude.

The 10.8 m long by 3.4 m high antenna assembly incorporates 7.3 m long by 2.7 m high Side-Emitting Electronic Manifold array, with the top hat supporting array providing 120° coverage on port and starboard side, while the top hat array itself provides 60° fore and aft, thus providing a complete 360° coverage. The radar's beam can be set for a 2° to 8° width, while scan duration can be set from 3 s to 40 s. Radar signal processing equipment and central computer are installed directly below the antenna array.

The cabin features eight operator consoles with sufficient space for four more; the Australian fleet will operate ten consoles with space for two more (four on starboard side and six on the port side).

Boron triazide. Boron triazide, also known as triazidoborane, is a thermally unstable compound of boron and nitrogen with a nitrogen content of 92.1 % (by the standard atomic weight). Formally, it is the triazido derivative of borane and is a covalent inorganic azide. The high-energy compound, which has the propensity to undergo spontaneous explosive decomposition, was first described in 1954 by Egon Wiberg and Horst Michaud of the University of Munich.

Preparation 
The first method is by the addition of diborane to a solution of hydrazoic acid in diethyl ether at a temperature range between −20 °C and −10 °C. This synthesis proceeds via the intermediates monoazidoborane, , and diazidoborane, .

The compound can also be obtained by passing boron tribromide vapor over solid silver azide in high vacuum.

A similar gas-phase synthesis uses the spontaneous reaction of boron trichloride with hydrazoic acid.

Properties 
The compound forms colorless crystals that are only stable at low temperatures. Above −35 °C, an explosive decomposition may occur. In the gas phase, generated boron triazide decomposes at room temperature within 60 minutes via loss of nitrogen gas to form boron nitrides with formulas  and BN. These reactions can also be initiated photochemically by UV radiation in the compounds absorption range at about 230 nm.

In contact with water, it undergoes hydrolysis to hydrazoic acid and boron trioxide.

Reaction with other azides like sodium azide or lithium azide yields the corresponding tetraazidoborate complexes.

The parent tetraazidoboric acid, , can be obtained at temperatures lower than −60 °C.

Uses 
Due to the low stability, the compound itself is not used as a high-energy substance. However, the tetraazidoborate derivatives and adducts with bases such as quinoline, pyrazine or 2,2,6,6-tetramethylpiperidine have potential for this usage. The gas-phase decomposition of the compound is also of interest as a method of coating surfaces with boron nitride.
