Preconception care for infertile couples: nurses' and midwives' roles in promoting better maternal and birth outcomes

Introduction Preconception care promotes better maternal outcomes, may assist in preventing birth defects and improves fertility awareness among healthy childbearing couples. Yet the significance of preconception care for infertile couples is undeveloped area of practice in Europe. Aim We discuss the importance of nurses and midwives in providing preconception care to infertile couples in the United Kingdom and Spain. Design Discursive paper Method A comparison of different midwifery and nursing approaches to preconception care for infertile couples in two European countries. Findings At present infertile couples’ needs for preconception care are not routinely identified or understood. There is an opportunity for these needs to be considered and identified by nurses at the time of investigation for infertility or when planning pregnancy with assisted conception. Conclusions We argue that by providing preconception care, nurses and midwives have an opportunity to deliver important advice to infertile couples in both primary care and specialist infertility services

Differences in larval morphology of allopatric isolated populations of the odontophrynus occidentalis group from western argentina

Remarks on some adaptive ecological trends of Pelobates cultripes from Portugal: thermal requirement, rate of development and water regulation

Spawning, tadpole biology, rate of development, tolerance to water loss and water absorption, of Pelobates cultripes from Portugal, were studied, having in mind similar researchs carried out on western American spadefoots.Material digitalizado en SEDICI gracias a la colaboración del Dr. Jorge Williams (FCNM-UNLP).Facultad de Ciencias Naturales y Muse

Osteological differences in allopatric populations of the Odontophrynus occidentalis group from Western Argentina

An osteological comparison of new-metamorphosed specimens from three populations of the O. occidentalis group was carried out. The results confirm the accentuated differentiation of the Sierra Famatina population.Material digitalizado en SEDICI gracias a la colaboración del Dr. Jorge Williams (FCNM-UNLP).Facultad de Ciencias Naturales y Muse

Probing halo nucleus structure through intermediate energy elastic scattering

This work addresses the question of precisely what features of few body models of halo nuclei are probed by elastic scattering on protons at high centre-of-mass energies. Our treatment is based on a multiple scattering expansion of the proton-projectile transition amplitude in a form which is well adapted to the weakly bound cluster picture of halo nuclei. In the specific case of $^{11}$Li scattering from protons at 800 MeV/u we show that because core recoil effects are significant, scattering crosssections can not, in general, be deduced from knowledge of the total matter density alone. We advocate that the optical potential concept for the scattering of halo nuclei on protons should be avoided and that the multiple scattering series for the full transition amplitude should be used instead.Comment: 8 pages REVTeX, 1 eps figure, accepted for publication in Phys.

Analysis of Control Strategies for Aircraft Flight Upset Recovery

This paper proposes a framework for studying the ability of a control strategy, consisting of a control law and a command law, to recover an aircraft from ight conditions that may extend beyond the normal ight envelope. This study was carried out (i) by evaluating time responses of particular ight upsets, (ii) by evaluating local stability over an equilibrium manifold that included stall, and (iii) by bounding the set in the state space from where the vehicle can be safely own to wings-level ight. These states comprise what will be called the safely recoverable ight envelope (SRFE), which is a set containing the aircraft states from where a control strategy can safely stabilize the aircraft. By safe recovery it is implied that the tran- sient response stays between prescribed limits before converging to a steady horizontal ight. The calculation of the SRFE bounds yields the worst-case initial state corresponding to each control strategy. This information is used to compare alternative recovery strategies, determine their strengths and limitations, and identify the most e ective strategy. In regard to the control law, the authors developed feedback feedforward laws based on the gain scheduling of multivariable controllers. In regard to the command law, which is the mechanism governing the exogenous signals driving the feed- forward component of the controller, we developed laws with a feedback structure that combines local stability and transient response considera- tions. The upset recovery of the Generic Transport Model, a sub-scale twin-engine jet vehicle developed by NASA Langley Research Center, is used as a case study

Further immunological evidence for the validity of the family Bombinidae (Amphibia Salientia)

New immunological data obtained using Libby’s photron-reflectro- metric technique confirms that Discoglossus belongs to a difíerent family (Discoglossidae Giinther, 1858) from that of Alytes and Bombina (Bombi- nidae Fitzinger, 1826).Nuovi dati immunologici ottenuti con la técnica fotronriflettometrica di Libby confermano che Discoglossus appartiene a una famiglia (Discoglossidae Giinther, 1858) diversa da quella di Alytes e di Bombina (Bombi- nidae Fitzinger, 1826).Material digitalizado en SEDICI gracias a la colaboración del Dr. Jorge Williams (FCNM-UNLP).Facultad de Ciencias Naturales y Muse
