(TR +UIB + U2B +H I2 Ef )4'p (x,R) =0, (2) The A( He, pp)B transfer reaction is of considerable theoretical interest in that the final state consists of three particles in the continuum. New data' for the reaction have recently become available on medium-mass targets. The observed pp coincidence spectrum shows significant enhancement at low pp relative energy e as a result of the strong final-s...

The fat body cells of Pachycondyla (=Neoponera) villosa are disposed in a single layer between the cuticle and the digestive tract, forming a group of cells enclosed by a thin membrane. Histological studies have revealed three different cellular types: trophocyte (more abundant), urate, (located among the trophocytes), and oenocyte (the scarcest), usually observed laying near the cuticle. Histo...

introduction: in this study the effect of matricaria recutita extract on acute pain in the presence and absence of flumazenil (antagonist of benzodiazepine) and lesioned paragigantocellularis (pgi) nucleus was investigated. method: wistar male rats (250±20 g) were used. animals were grouped randomly into intact, sham and bilateral lesion of pgi nucleus. intact and lesioned animals, each divided...

Carbon catalyst consisting of a hybrid structure made up of amorphous carbon and nanographite was prepared from the leaves of Pinus Roxburghii. The catalyst was prepared through sodium hydroxide and hydrochloric acid treatment of the dried pine leaves; and further functionalized with sulfuric acid treatment to incorporate the acidic functionalities. The synthesized catalyst was characterized by...

Heavy quarks are produced in the early stages of nucleus-nucleus collisions and can therefore provide important insight into Quark-Gluon Plasma (QGP). Quarkonia proposed as crucial probes to study QGP. The extent medium modification for heavy-quark quarkonium production heavy-ion is measured terms a nuclear factor $R_{\rm AA}$, defined yield divided by relative cross section pp scaled overlap f...

In recent years, we constructed a microscopic optical potential (OP) for elastic nucleon-nucleus ($NA$) scattering using modern approaches based on chiral theories the nucleon-nucleon ($NN$) interaction. The OP was derived at first order of spectator expansion in Watson multiple theory and its final expression folding integral between $NN$ $t$ matrix nuclear density target. Two- three-body forc...

In conventional nuclear experiments a beam of accelerated nuclei collides with a target nucleus that is surrounded by other nuclei in a molecule, or in condensed matter, or in plasma environment. It is shown that for low collision energies the nuclear reaction is strongly boosted by the environment. The effect originates from a chain of preliminary three elastic collisions which transform the p...

The 28 Si(p,p ′ γ 0 X) 24 Mg reaction has been studied at the ITEP accelerator by the hadron-gamma coincidence method for a proton energy of 1 GeV. Two reaction products are detected: a 1368.6-keV γ-ray photon accompanying the transition of the 24 Mg * nucleus from the first excited state to the ground state and a proton p ′ whose momentum is measured in a magnetic spectrometer. The measured di...

The ocular tilt reaction composes a triad of ipsiiateral head-tilt, ipsilaterai conjugate ocular torsion, and skew deviation with ipsilaterai hypotropia. It results from a disruption of central vestibular pathways conveying information from the semicircular canals and otoliths. Skew deviation is one component of the syndrome which may or may not be associated with the concomitant torsion and he...

Twinning nucleation in a medium Mn austenitic steel containing precipitates is studied at low strain ~ 0.02, using transmission electron microscopy. In the near vicinity of precipitates, unfaulting dislocation reaction favored, while twinning activated farther from precipitates. Twin follows hybrid mechanism, involving creation stacking faults through classical dissociation, those subsequently ...
