Half sandwich compound
Half sandwich compounds, also known as piano stool complexes, are organometallic complexes that feature a cyclic polyhapto ligand bound to an MLn center, where L is a unidentate ligand. Thousands of such complexes are known. Well-known examples include cyclobutadieneiron tricarbonyl and (C5H5)TiCl3. Commercially useful examples include (C5H5)Co(CO)2, which is used in the synthesis of substituted pyridines, and methylcyclopentadienyl manganese tricarbonyl, an antiknock agent in petrol.

MMT is a commercially useful antiknock compound.

CpCo(CO)2 is a catalyst for the synthesis of pyridines.

(C4H4)Fe(CO)3.

CpFe(CO)2I is an example of a piano stool complex with two different monodentate ligands.

The diruthenium of cymene is readily cleaved by ligands to give monoRu half-sandwich derivatives.

Vétra
Vétra (or Vetra), or more formally the Société des Véhicules et Tracteurs Electriques,
was a French manufacturer of trolleybuses and electric locomotives.
Founded in 1925, it became one of Western Europe's largest builders of trolleybuses during the middle decades of the 20th century, making in excess of 1,750 vehicles, for cities in France and in several other countries. The company ceased production in 1964.

Trolleybuses in Saint-Étienne
The Saint-Étienne trolleybus system (French: Réseau de trolleybus de Saint-Étienne) forms part of the public transport network of the city and commune of Saint-Étienne, in the Rhône-Alpes region of the Great South East of France.

In operation since 1942, the system is one of four operating trolleybus systems in France; the others are in Limoges, Lyon and Nancy. Today, the city is taking major steps to develop trolleybus transport. New battery trolleybuses Solaris T12 with ŠKODA electric equipment were purchased. In addition, the number of vehicles was increased compared to the original fleet so that electric traffic could be resumed on the M7 Michon - city center - Bellevue line. In the near future, trolleybuses will also return to the M6 line serving the Metare housing estate, where a trolley line is now being built again. In addition, the line will use the planned BRT corridor and the carrier will purchase articulated trolleybuses for it. These should also appear on the M4 line.

Shoulder problems
Shoulder problems, including pain, are one of the more common reasons for physician visits for musculoskeletal symptoms. The shoulder is the most movable joint in the body.  However, it is an unstable joint because of the range of motion allowed. This instability increases the likelihood of joint injury, often leading to a degenerative process in which tissues break down and no longer function well.

Shoulder pain may be localized or may be referred to areas around the shoulder or down the arm. Other regions within the body (such as gallbladder, liver, or heart disease, or disease of the cervical spine of the neck) also may generate pain that the brain may interpret as arising from the shoulder.

Acromioclavicular joint
The acromioclavicular joint, or AC joint, is a joint at the top of the shoulder. It is the junction between the acromion (part of the scapula that forms the highest point of the shoulder) and the clavicle. It is a plane synovial joint.

Ionic meter
The ionic (or Ionic) is a four-syllable metrical unit (metron) of light-light-heavy-heavy (u u – –) that occurs in ancient Greek and Latin poetry. According to Hephaestion it was known as the Ionicos because it was used by the Ionians of Asia Minor; and it was also known as the Persicos and was associated with Persian poetry. Like the choriamb, in Greek quantitative verse the ionic never appears in passages meant to be spoken rather than sung. "Ionics" may refer inclusively to poetry composed of the various metrical units of the same total quantitative length (six morae) that may be used in combination with ionics proper: ionics, choriambs, and anaclasis. Equivalent forms exist in English poetry and in classical Persian poetry.

Resolution (meter)
Resolution is the metrical phenomenon in poetry of replacing a normally long syllable in the meter with two short syllables. It is often found in iambic and trochaic meters, and also in anapestic, dochmiac and sometimes in cretic, bacchiac, and ionic meters. In iambic and trochaic meters, either the first or the second half of the metrical foot can be resolved, or sometimes both.

The long syllables of dactylic meter are not usually resolved, and resolution is also not found in the last element of a line.

The opposite of resolution is contraction, which is the substitution of one long syllable where the metrical pattern has a double short. Such a position, which is normally two short syllables, as in a dactylic hexameter, is known as a biceps element.
