Peptide growth factors and preimplantation development

Kane, M. (Oxford University Press (OUP), 1997-03-01)

This paper examines some of the problems and questions that must be considered in relation to research on the role of growth factors in preimplantation embryos. It reviews and summarizes the large body of work on gene ...

Boundary value problems for general discrete systems on infinite intervals

Agarwal, R.P.; O'Regan, D. (Elsevier BV, 1997-04-01)

This paper continues the study of boundary value problems for a discrete system which in particular includes the prototype equation x(k + 1) = f(k, x(k)), equations with finite as well as infinite delays, equations of ...

(IOP Publishing, 1997-11-01)

PSR B1951 + 32 is a gamma-ray pulsar detected by the Energetic Gamma Ray Experiment Telescope (EGRET) and identified with the 39.5 ms radio pulsar in the supernova remnant CTB 80. The pulsar energy spectrum is consistent ...

Influence of medium composition on the growth and antigen expression of helicobacter pylori

Walsh, E.J.; Moran, A.P. (Wiley-Blackwell, 1997-06-01)

An evaluation of the ability of various solid and liquid media to support both growth and antigen expression, particularly lipopolysaccharide (LPS) expression, by Helicobacter pylori culture collection strains and clinical ...

C.; Zweerink, J. (IOP Publishing, 1997-10-01)

We present multiwavelength observations of the BL Lacertae object Markarian 501 (Mrk 501) in 1997 between April 8 and April 19. Evidence of correlated variability is seen in very high energy (VHE; E greater than or similar ...

The shelf-edge current north-west of ireland

White, M.; Bowyer, P. (Copernicus GmbH, 1997-01-01)

Measurements of the slope current at two locations north-west of Ireland have been made between April and December 1994, 40 m above the seabed in a water depth of 660 m. A persistent poleward along-slope current was observed ...
