Orange is one of the most horticulturally important and widely cultivated Citrus species. cultivar improvement via conventional breeding strategies normally impeded by factors related to its reproductive biology. The present study was undertaken investigate optimization growth regulators’ composition media in vitro propagation orange from nodal segment explants. explants were collected sweet cu...

ABSTRACT Blade failure is a common problem of a steam turbine and it’s failure in-service results in safety risks, repair cost and non operational revenue losses. Thus, the reliability of these blades is very important for the successful operation of a steam turbine. Dynamic analysis of a steam turbine blade in computational environment is carried out in the present work. In order to gain physi...

BACKGROUND Secondary metastasis to regional lymph nodes for adjacent bowel invaded by colorectal cancers (CRCs) has not been extensively reviewed. We herein present three such cases. CASE PRESENTATION The first case is a cancer involving the cecum and sigmoid colon, and its primary site could not be determined even by pathological evaluation. Nodal involvement was revealed both in the mesocol...

introduction: the ablation technique is one of the important therapeutic interventions for treatment of av nodal tachyarrhythmia. different animal models have been developed to study the effects of ablation on the functional interanodal structure. the aim of the present study was to develop a new model of computer analysis to produce lesions by using direct voltage in isolated perfused rabbit a...

Introduction: The ablation technique is one of the important therapeutic interventions for treatment of AV Nodal tachyarrhythmia. Different animal models have been developed to study the effects of ablation on the functional interanodal structure. The aim of the present study was to develop a new model of computer analysis to produce lesions by using direct voltage in isolated perfused rabbi...

We study the nodal sets of eigenfunctions of the Laplacian on the standard d-dimensional flat torus. The question we address is: Can a fixed hypersurface lie on the nodal sets of eigenfunctions with arbitrarily large eigenvalue? In dimension two, we show that this happens only for segments of closed geodesics. In higher dimensions, certain cylindrical sets do lie on nodal sets corresponding to ...

Direct electrical excitation of small cardiac branches from the thoracic vagus elicited highly localized and differential responses from individualized segments of the myocardium. For example, small nerves from the vagus at the level of the superior pulmonary veins frequently induced moderate inhibition in contractile force of the ipsilateral atrium with little or no influences elsewhere. Bran...

The author has been using post-nodal segments of early chick blastoderms as an experimental system to study early morphogenesis and differentiation. The segment is produced by a transverse cut at about 0-4 mm from the primitive pit and is known for its very limited potencies in chorio-allantoic transplantation or in culture, in contrast to anterior parts containing Hensen's node (Hunt, 1931; Wi...
