  • Cropping Systems
  • Plant and Crop Production
CONT

Break crops generally refer to a pulse or oilseed crop grown instead of cereals. The decision not to grow wheat but to grow and choose a break crop is based on many factors including the relative profitability of the crops – yield by price, the cereal disease pressure, herbicide resistance and personal preference.

CONT

Simpson’s Obstetrical Forceps ... Developed in 1848 by Dr. James Simpson of Edinburgh, these forceps were a combination of features from earlier models. He retained the finger rests and deep finger depressions in the handle and connected the forceps with a notched joint.

CONT

James Young Simpson(1842) adapted the design of forceps to include a prominent pelvic curve with parallel shanks and an articulating lock. The space created with the divergence of the shanks allows for finger positioning and control of the molded head of the fetus. They have an elongated and flattened cephalic curve, which provides minimal trauma in traction, and are best suited to deliveries witout need of major rotation.

OBS

The credit for the invention of the precursor of the modern forceps to be used on live infants goes to Peter Chamberlen of England (circa 1600). Modifications have led to more than 700 different types and shapes of forceps. In 1745, William Smellie described the accurate application to the occiput, rather than the previously performed pelvic application, regardless of the position of the head. In 1845, Sir James Simpson developed a forceps that was designed to appropriately fit both cephalic curvatures and pelvic curvatures. In 1920, Joseph DeLee further modified that instrument and advocated the prophylactic forceps delivery. In an era in which many women labored and delivered under heavy sedation, forceps deliveries became common. ... When forceps deliveries are performed, Simpson forceps... is the instrument most commonly used for outlet- and low-forceps deliveries.

OBS

Elliot forceps are used for the unmolded head while Simpsons forceps are used for the molded head. Specialized forceps include rotational forceps such as Kielland, Barton, and Piper forceps (for the after-coming head of a breech).

OBS

In medical eponyms, the possessive form, such as "Simpson’s forceps", often disappears over the years. For that reason, the written forms "Simpson’s forceps" and "Simpson’s obstetrical forceps" are also found.

French

Domaine(s)
  • Instruments chirurgicaux
DEF

Forceps utilisé en obstétrique afin de réduire la pression exercée sur la tête fœtale.

OBS

Les forceps anglais (Smellie, Davis, Simpson, Barnes) ont une articulation par emboîtement : la branche gauche présente une sorte d'encoche, des fourche, dans laquelle est reçue la partie articulaire de la branche droite.

OBS

Avec l'usage, il arrive que le nom de l'inventeur ne soit plus utilisé comme complément de nom, mais soit mis en apposition et se comporte, dès lors, comme un adjectif de relation. On parlera alors de «forceps Simpson» et non plus de «forceps de Simpson».

Subject field(s)
  • Surgical Instruments
DEF

An obstetrical forceps having a sliding lock and little pelvic curve.

OBS

Kielland's forceps [were] originally designed to deliver the fetal head at or above the pelvic brim, lying in the transverse axis of the pelvis and rotating it when it had reached the pelvic cavity. The forceps is used today for rotation and extraction of the head which is arrested in the deep transverse or occipito-posterior position. The blades have very little pelvic curve and are virtually an axis traction forceps. A large episiotomy is needed. The shallowness of the curve allows safe rotation in the vagina. Downward traction encourages rotation of the head. The claw lock allows the blades to slide on each other and correct or encourage synclitism of the fetal head as required. The range of movement allowed by the lock makes it possible to apply lethal compression to the fetal head if the instrument is used improperly

CONT

If the fetus's head needs to be rotated, there is now a tendency to use manual rotation, rotation with a vacuum extractor, or caesarean section in preference to Kielland's rotational forceps. This change in practice arose in the 1980s after high rates of neonatal morbidity and mortality were associated with Kielland's forceps... Kielland's forceps are only used for select cases and by experienced obstetricians.

OBS

In medical eponyms, the possessive form, such as "Kielland’s forceps" (Christian Kielland or Kjelland, Norwegian obstetrician) often disappears over the years. For that reason, the written forms "Kjelland forceps" and "Kielland forceps"are also found.

  • Paleontology
OBS

(...) the process of "torsion" involves a rotation of the mantle [of a young prosobranch gastropod], and [the] juvenile shell, with its enclosed viscera, through an angle of 180 degrees in relation to the velum(from which the head later develops) and the foot. As a result the mantle cavity comes to occupy an anterodorsal position, while the coiling of the shell assumes the endogastric direction typical of the adult gastropod. Effects of this torsion on the cells from which various organs of the adult animal later arise are far-reaching. Thus, when they develop, the nerve cords connecting the cerebral and pleural to the visceral ganglia are found to be crossed(...) rather like a figure 8, instead of being parallel. The gut has been twisted into a loop. It is, moreover obvious that the positions of the left and right ctenidia, osphradia, hypobranchial glands, heart auricles, and kidneys of the ancestral untorqued form become transposed as the result of torsion, so that when, as in most prosobranchs, only one of each of these organs remains, this, although now on the 6ft-hand side, represents the original right-hand organ.

Cette torsion non seulement affecte le sac viscéral et la coquille qui moule le manteau en leur imprimant une forme hélicoïdale, mais entraîne aussi le "chiasma" du système nerveux dont les ganglions, initialement placés à droite, vont prendre une position topographique gauche et "vice versa". Et surtout, la principale conséquence de la torsion hélicoïdale est d'avoir transformé les Gastéropodes en animaux dissymétriques: l'étude des parties molles prouve que les organes pairs du côté droit (côté gauche originel) sont plus petits que ceux du côté gauche, et peuvent même s'atrophier et disparaître.
