"in mathematics ... we find two tendencies present. On the one hand, the tendency toward abstraction seeks to crystallize the logical relations inherent in the maze of material that is being studied, and to correlate the material in a systematic and orderly manner. On the other hand, the tendency toward intuitive understanding fosters a more immediate grasp of the objects one studies, a live ra...

Lung health and normal mucus clearance depend on adequate hydration of airway surfaces. Because transepithelial osmotic gradients drive water flows, sufficient hydration of the airway surface liquid depends on a balance between ion secretion and absorption by respiratory epithelia. In vitro experiments using cultures of primary human nasal epithelia and human bronchial epithelia have establishe...

For steady states of cells that have uniform cell membranes, there must be zero net fluxes of each ion. This provides a set of conditions more restrictive than the condition of zero net current flow that is used to derive the Goldman equation. We show that this leads to a set of general relations between the membrane potential, ion activities, ion permeabihties, and pump fluxes and that the Gol...

This article stresses the main lines of Thomas Aquinas's philosophy on the nature of the body-soul union. Following Aristotle, Aquinas sees the soul as a 'principle of life' which is intimately bound to a body. Together they form a non-contingent composition. In addition, the distinctive feature of the human soul is rationality, which implies that a human needs a mind to be what it is. However,...

AIM To report a study exploring prospective relations between nurses' perceived work ability and three forms of turnover intentions, respectively, intent to leave the ward, organization and profession. BACKGROUND Turnover of nursing staff is a major challenge for healthcare settings and for healthcare in general, urging the need to improve retention. DESIGN Survey. METHODS Based on the lo...

This paper reports the sexual risk behaviour among migrant tribal community living in an eastern Indian city.

The paper investigates the logic underlying statements of the form “X counts as Y in context C” which are commonly considered to represent the paradigmatic syntax of constitutive rules, i.e., the nonregulative component of normative systems. The analytical thesis backing the whole work consists in interpreting such statements as contextual classifications. This reading of counts-as is thoroughl...

Quality social relationships depend, in part, on deferring self-interest to another person or group. Being too arrogant or self-focused could negatively affect relationship quality. In two studies we examined possible connections between trait humility and social relationship quality (SRQ). Participants completed survey measures of each construct. Self and peer-reported humility correlated posi...
