(n.) A kind of hooked instrument for untwisting old cordage.
Example Sentences:
(1) Whereas all extant vertical clingers and leapers share certain femoral traits (i.e., long femur, proximally restricted trochanters, ventrally raised patellar articular surface), Galagidae and Tarsiidae share features of the proximal femur (i.e., cylindrical head, large posterior expansion of articular surface onto the neck) that clearly distinguish them from the specialized leapers of the Malagasy Republic (Indriidae and Lepilemur).
(2) The tarsal bones referred to Arapahovius suggest that animals in this genus were habitual leapers.
(3) In small-bodied leapers we therefore find adaptations that increase the distance or length of time for propulsion and maximize speed.
(4) Accordingly, large-bodied leapers have adaptations that allow optimal use of available muscle force.
(5) In an arm-swinging movement, the long, heavy arms of the large-bodied leapers are effectively used to gain additional momentum.
(6) Species which exploit a 3-dimensional environment and execute fast and complicated head and body movements have a larger VC than closely related species confined to the ground or which are less skilled leapers.
(7) In order to relate the details of locomotor behaviour to a certain environment, the biomechanics of jumping are analyzed in five primate species: The three mainly arboreal prosimian species Galago moholi, the smallest and most specialized leaper of all, Galago garnettii, a medium-sized bushbaby with some capacities for jumping, and Lemur catta also with some abilities to jump.
(8) Contrary to the most common view, the euprimate morphotype was probably not a specialized leaper.
(9) Some traits suggested as being characteristic of vertical clingers and leapers (i.e., deep femoral condyles facing posteriorly, narrow patellar groove with prominent lateral margin, greater trochanter overhanging anterior aspect of shaft) are shown to be common to all prosimians except the slow-climbing lorisids.
(10) How does body size determine the locomotor performance and proportions of leapers?
(11) Not only the dentition shows different morphs, but also postcranial material represents two vertical clingers and leapers of different size.
(12) In addition, take-offs of the larger-bodied leapers are characterized by a regularly occurring arm swing movement, thus making additional use of nonhindlimb muscles for acceleration.
Untwist
Definition:
(v. t.) To separate and open, as twisted threads; to turn back, as that which is twisted; to untwine.
(v. t.) To untie; to open; to disentangle.
Example Sentences:
(1) The DNA untwisting enzyme has been purified approximately 300-fold from rat liver nuclei.
(2) Prompt diagnosis, in which timely diagnostic laparoscopy and ultrasound evaluation of the pelvis may be helpful, provides the opportunity for prompt laparotomy with untwisting of the torsion and stabilization of the adnexa by suture and cystectomy, if possible, extirpation if not.
(3) In group I (torsion maintained), unilateral torsion of the spermatic cord was maintained until the day of sacrifice; in group II (torsion and untwist), torsion of the spermatic cord was maintained for 8 to 12 hours, then the spermatic cord was untwisted and the testis was retained until the day of sacrifice.
(4) With resolution of rejection, M(early-dia) and percent untwist during early diastole returned to baseline levels (p = NS versus baseline).
(5) From the intersection points, epicardial and endocardial circumferential chord and arc lengths were measured and angular twist of mid and apical levels with respect to the base (maximal torsion and its reversal, untwisting) was calculated.
(6) Histone cores partly dissociate within the temperature range of 25 to 40 degrees C. Quantitative analysis of histone thermal dissociation from DNA shows that the size of DNA protected against thermal untwisting would be significantly overestimated if this effect is neglected.
(7) Footprinting experiments demonstrated that EBNA-1 binds to oriP in a sequence-specific manner and bends or untwists the DNA at two symmetry-related sites in region II.
(8) It is important that the thoracic kyphosis be recreated, firstly so that the spine can be untwisted, and secondly to bring the thoracic spine once again behind its axis of rotation thus preventing postoperative buckling with the remainder of growth.
(9) If a mixture of complementary single-stranded rings is annealed and then treated with the DNA untwisting enzyme, the DNA circles completely renature as judged by (i) the presence of interlocked rings that sediment at 53 S in alkali, (ii) the buoyant density of the renatured DNA in CsCl gradients containing ethidium bromide, and (iii) the resistance of the product to the single-strand-specific S1 nuclease.
(10) The later was used for establishing the diagnosis and furthermore for untwisting the adnexa.
(11) This purified fraction shows a DNA topoisomerase activity that untwists superhelical DNA in an ATP- and Mg2+-dependent reaction.
(12) However, if prompt diagnosis is made and viable tissue found (laparoscopy may be helpful), the opportunity of untwisting the adnexa and salvaging of ovarian function and fertility should be taken.
(13) When a simple volvulus is found, the loop should be untwisted and the gaseous contents siphoned off by menas of a rectal catheter.
(14) It is shown in this case that untwisting is negligible and bending significant.
(15) A DNA molecule containing a single strand break was shown to be an intermediate in the untwisting reaction.
(16) The DNA untwisting enzyme relaxes covalently closed circylar DNAs by the sequential breaking (nicking) and closure of one strand of the duplex.
(17) Both mathematic computation of velocity distribution in the impeller and geometric illustration of the velocity triangle at the top of the vane have demonstrated that the peripheral velocity variation of blood cells in a twisted impeller will be less than that in an untwisted impeller.
(18) These results show that the DNA in the SV40 chromatin which is accessible to the DNA untwisting enzyme is under no topological strain.
(19) They had all undergone surgical untwisting with replacement of the nonviable testis in the scrotum during prepubertal period.
(20) The assembly of this dodecamer initiates an untwisting of the duplex by 2-3 turns.
