European hazard symbols. European hazard symbols for chemicals are pictograms defined by the European Union for labelling chemical packaging (for storage and workplace) and containers (for transportation). They are standardised currently by the CLP/GHS classification.

GHS hazard pictograms

The European Union CLP Regulation (for "Classification, Labelling and Packaging") was introduced as EC Regulation 1272/2008. It is based on the GHS system, to secure for "physical, health and environment hazards".

The European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR) fixed harmonised pictograms for transportation. Vehicles carrying dangerous goods have to be fitted with orange signs, where the lower number identifies the substance, while the upper number is a key for the threat it may pose.

Chemical warning signage
Directive 92/58/EEC provides several safety signs for identifying dangerous materials and areas where they are handled and stored.

Former hazard pictograms (1967–2017)
The previous hazard symbols for chemicals, were introduced in the Directive Directive 67/548/EEC, in 1967, and required to be adopted no later than 1 January 1970. The symbols were also included as a part of Directive 1999/45/EC. The symbols were replaced from 1 December 2010 to 1 June 2017, via a gradual phaseout. After 1 June 2017, Directive 67/548/EEC symbols were no longer allowed to be used.

From 1967 to 2017, these symbols were used for labeling containers and piping systems containing dangerous substances/mixtures. These symbols could also be used to identify areas where dangerous substances/mixtures were being stored in large quantities, as an alternative to the yellow triangular Directive 92/58/EEC warning signage.

Buzz Bombers. Buzz Bombers is a fixed shooter video game developed by Mattel Electronics for its Intellivision system and released in 1982. Mattel's reaction to Atari's popular Centipede, the player controls a can of bug spray trying to ward off swarms of bees.

Gameplay

In Buzz Bombers, the player character takes the form of a can of bug spray, protecting a garden of flowers from bees. The player's spray can fires shots of bee repellent that will turn the bee into a piece of honeycomb. The standard worker bees will fly left and right above the garden, reversing direction whenever they reach the edge of the screen or a piece of honeycomb. At the edge of the screen, the bee will drop one level closer to the garden. In later levels, killer bees will appear, which move much faster than the regular bees and are unaffected by honeycombs; killer bees turn into pieces of red honeycomb when shot. If a regular bee is trapped between two obstacles, it will form a beehive, which is worth bonus points at the completion of the level.

Should a bee of either type reach the bottom of the screen, it produces a flower. Flowers will begin to reduce the amount of space available to the spray can, potentially to the point where it is unable to move, destroying the spray can and costing the player one life.

The garden is also inhabited by a friendly hummingbird. The hummingbird will appear intermittently and will eat the honeycombs on the screen in a random order, giving additional points to the player; red honeycombs are worth more points than standard honeycombs. While invulnerable to the spray can's shots, the hummingbird will flee temporarily if it is hit too many times. The spray can's shots will also destroy honeycombs and beehives, forcing the player to aim carefully to avoid losing bonus points.

Points are scored for each bee (worker or killer) shot, as well as each honeycomb upon which the hummingbird feeds. When a level is completed by destroying a certain number of bees, bonus points are awarded for any beehives on screen.

Development

During the game's development, a prototype was prepared where the spray can was branded as a can of Raid, a brand of insecticide produced by SC Johnson, in an attempt to get the company to partner on the game's promotion; SC Johnson declined the offer. As the game went into mass production, the information on the box indicated that Buzz Bombers allowed two players to play, an error which forced the incorrect information to be corrected by hand on every game box prior to shipment.

Legacy
Buzz Bombers was re-released as part of the Intellivision Lives! collection for computers and other game consoles. In May 2010, Buzz Bombers was made available on Microsoft's now defunct Game Room service for its Xbox 360 console and for Games for Windows Live.

Berrechid–Beni Mellal expressway. The Berrechid–Beni Mellal expressway (A4) was inaugurated in 2015. It runs mainly parallel with the existing Route Nationale 12.

History

Start of building
On 12 April 2010 King Mohammed VI of Morocco formally started the building-activities for this  long toll-road. Between this date and the opening in 2015, some  of soil/ground were moved.

Financing
The total building costs are budgeted on 6.050 million Dirham and these investments are made via:
FADES: The Arab Fund for Social and Economical Development,
the European Investment Bank and the government of China. This investment will be retrieved via the income from the toll-road, the exploration of the rest- and service stations. Three service-stops will be built lying max. . apart from each other.
The five parts were meant to be built at the same time so that the whole road can be opened for traffic in 2013. However, due to expropriation issues, Khouribga - Beni Mellal section opened in 2014 and the inauguration of Berrechid - Khouribga section was postponed to 2015. 

This investment is part of the main-project plan 2008–2015 between the ADM and the government of Morocco. This masterplan was signed on 8 July 2008 during a formal meeting which was attended by King Mohammed VI of Morocco.

Construction

The first section between Berrechid and Ben Ahmed () was built by China International Water & Electric Corporation (CWE). The second section, between Ben Ahmed and Khouribga (), and the third section between Khouribga and Oued Zem (), were built by four local Moroccan contractors: Sintram, LRN, Seprob and the SNCE. The fourth one between Oued Zem and Kasba Tadla () was built by a Moroccan contractor, Houar. The fifth and last one, between Kasba Tadla and Beni Mellal ( ) was by another Chinese contractor, Covec.

Purpose
This expressway aims to support the development of Béni Mellal-Khénifra region and to reduce road traffic on the National road 11. This expressway links Beni Mellal, capital of Béni Mellal-Khénifra region, to Casablanca, the economic capital and the largest city in Morocco, serving the province of Khouribga, an area of great industrial potential thanks to large phosphate reserves. The Béni Mellal-Khénifra region's agricultural and tourism sectors are also expected to benefit from this expressway.

With traffic estimated at 3,700 vehicles per day (2018), the expressway serves the cities of Ben Ahmed, Khouribga, Oued Zem, Bejaad and Kasba Tadla. It includes 7 junction and 3 bridges across the Oum Errabiaa, Oued Derna and Oued Oum Errabia Bouqroum rivers as well as 28 underground and aerial passages.

Route
The total length of the new expressway from Berrechid to Beni Mellal is .

Royal Aircraft Factory F.E.3. The Royal Aircraft Factory F.E.3 (also known as the A.E.1 ("Armed Experimental") was a British experimental single-engined pusher biplane built prior to the First World War. It was intended to be fitted with a shell-firing gun, but was quickly abandoned, being found to be structurally unsound.

Design and development

In 1913, the Royal Aircraft Factory designed an experimental armed pusher biplane, the F.E.3 ("Farman" or "Fighting" Experimental), with the alternative designation A.E.1 ("Armed Experimental"). The F.E.3 was to carry a Coventry Ordnance Works 1½ lb shell-firing quick loading gun.  In order to reduce the drag associated with the pusher layout favoured for gun-carrying aircraft, the tail was carried on a single tubular tailboom connected by bearings to the four-bladed propeller, with bracing wires running to the wings and undercarriage. The crew of two, gunner and pilot, sat in tandem in a wood and metal nacelle. The aircraft was powered by a single water-cooled Chenu inline engine mounted in the nose of the nacelle, connected to a long shaft running under the cockpit which drove the propeller using a chain drive.  The gun was to fire through the cooling intake for the engine.

It flew in the summer of 1913, but testing was stopped after the aircraft's propeller broke in flight resulting in a forced landing.  Flight testing did not resume, as it was realised that the tailboom was not strong enough to allow safe flying.  Although the F.E.3 did not fly again, the gun installation was test fired with the aircraft suspended from a hangar roof, showing that recoil loads were not excessive.

Junkers T 29. The Junkers J 29 was a two-seat, single-engined experimental training monoplane, built in Germany in 1925. Its significance is that it was the first aircraft to fly and test the Junkers Doppelflügel (double wing) control surfaces used very successfully on the later Junkers Ju 52.

Design and development

.
The Junkers J 29 was a small, aerodynamically clean low wing cantilever monoplane, constructed with Junkers' standard method of duralumin tube frames skinned with corrugated sheets of the same alloy. The wing of the J 29 was straight tapered, almost entirely on the trailing edge and had nearly square tips.  The J 29 pioneered the patented Junkers Doppelflügel "double wing" control system - whose concept was used through to the Third Reich's Junkers Ju 87 Stuka dive bomber - using full span ailerons, later used for both ailerons and flaps, hinged just below the wing trailing edge and fully exposing the entire control surface cross-section to the slipstream, forming a slot between the two surfaces.  In normal flight these were used as standard ailerons, but they could be lowered like flaps for landing whilst retaining the differential movement needed for lateral control.

The fuselage was flat sided with rounded decking, the Junkers L1a inline engine cowled with its cylinder heads slightly exposed.  Pilot and passenger sat side by side over the wing in a cockpit open apart from a longitudinal arch over their heads to protect them like a roll bar, set perpendicularly to the similar cross-fuselage device only used directly behind the cockpit on the Junkers J 2, the Junkers J 7 experimental duralumin-structure monoplane and production Junkers D.I fighter of the late World War I years.  This unusual feature reminded observers of a handle and earned the J 29 the nickname Bügeleisen (en: flat iron). The fuselage tapered to the parallel chord tailplane braced on top of it.  The fin was blunt and the rudder wide chord and deep, moving within a cut out in the elevators.  Neither rudder nor elevators were horn balanced.  The fixed undercarriage had a standard Junkers layout, with short splayed main legs fitted with noticeable shock absorbers mounted to the forward wing root and braced forwards to points under the engine.  The wheels were linked by a centrally hinged cross axle, mounted on a V strut below the fuselage.

The first of two J 29s flew in April 1925. Though they had a Junkers sales description as the T 29, suggesting a training role and a hope of sales, they seem to have been built primarily to flight test the double wing which was successfully used on later Junkers aircraft such as the G 28, the Ju 52/3m and the Ju 87.

Arbor Networks. Arbor Networks is a software company founded in 2000 and based in Burlington, Massachusetts, United States, which sells network security and network monitoring software, used – according to the company's claims – by over 90% of all Internet service providers. The company's products are used to protect networks from denial-of-service attacks, botnets, computer worms, and efforts to disable network routers. The service employs port scanning from the IP range 146.88.240.0/24 in which threats are being detected.

History
The company was founded in 2000 when co-founders Farnam Jahanian and Rob Malan spun out research from the University of Michigan, sponsored by DARPA, Cisco, and Intel. They were joined by students Jonathan Arnold, Matthew Smart, and Jonathan Poland, and entrepreneurs Ted Julian and Dug Song to make the founding team.  The company raised $11 million in a round of venture capital. Later, in August 2002, the company raised another $22 million in a second round of venture capital, led by Thomas Weisel Venture Partners, with participants that included Battery Ventures and Cisco Systems, among others. In January 2008, Arbor acquired Ellacoya Networks, a company which provides broadband traffic shaping products. The acquisition was expected to increase the total addressable market (TAM) for Arbor to $750 million in 2008, and to $1.5 billion by the end of 2009. In March 2009, Arbor worked with 100 ISPs to create a new network monitoring system, called ATLAS 2.0. In October 2009, the company estimated that Google paid almost nothing for YouTube's bandwidth, noting that Google probably used dark fibre instead to run the website.

On August 31, 2010, Tektronix Communications announced that it has completed its acquisition of Arbor Networks.  Upon completion of the acquisition, Arbor Networks joins Danaher Corporation's portfolio of communications and enterprise companies, which includes Tektronix Communications.

On September 3, 2013, Arbor Networks announced that it had acquired privately held Packetloop, a leader in Security Analytics based in Sydney, Australia.

Company
Arbor has strategic partnerships with Cisco, IBM, and Juniper Networks. In addition to its headquarters in Burlington, Massachusetts, the company also has offices in Ann Arbor, Michigan, London, and Singapore.  Wired stated that due to the popularity of Arbor's software among ISPs, the company "likely knows more about the [Internet's] ebbs and flows than anyone outside of the National Security Agency".

Arbor is now part of NetScout Systems as part of the acquisition of Fluke, Tektronix Communications (TekComms) and VSS in 2015 from Danaher.

Socofer. Socofer is the name for the railway construction company that before 1968 was known as Établissements Billard.

History
Socofer, a French company established in 1965, acquired the railcar fabrication business of Billard the same year. The Billard mechanical shop was founded in 1920 and their completed their first rolling stock two years later. In 1928, the growth of the business led to the incorporation of Société Anonyme des Anciens Etablissements BILLARD et Cie.

LIFER/LADDER. LIFER/LADDER was one of the first database natural language processing systems. It was designed as a natural language interface to a database of information about US Navy ships. This system, as described in a paper by Hendrix (1978), used a semantic grammar to parse questions and query a distributed database. 

The LIFER/LADDER system could only support simple one-table queries or multiple table queries with easy join conditions.

Some examples of queries it could accept:
What are the length, width, and draft of the Kitty Hawk?
When will Reeves achieve readiness rating C2?
What is the nearest ship to Naples with a doctor on board?
What ships are carrying cargo for the United States?
Where are they going?
Print the American cruisers’ current positions and states of readiness?
