An investigation was conducted to determine whether intermittent exposure to 3% CO2 results in a saturation of the body with carbon dioxide and whether a compensation of the respiratory acidosis is induced by carbon dioxide inhalation. One healthy male subject was exposed for six days, 15 hours daily, to a CO2 concentration rising from 0 3% at normal oxygen concentrations of 20 21% O2. Average ...

What is John Dewey’s Democracy and Education? In a literal sense, it is a study of education and its relation to the individual and society. Moreover, Dewey tells us, it is a philosophical rather than historical, sociological, or political inquiry. His original title for the work was An Introduction to the Philosophy of Education. That was the heading he had in view when he signed a contract to...

We consider a class of linear programs involving a set of covering constraints of which at most k are allowed to be violated. We show that this covering linear program with violation is strongly NP-hard. In order to improve the performance of mixed-integer programming (MIP) based schemes for these problems, we introduce and analyze a coefficient strengthening scheme, adapt and analyze an existi...

This work is focused on deformation activity mapping and monitoring using Sentinel-1 (S-1) data and the DInSAR (Differential Interferometric Synthetic Aperture Radar) technique. The main goal is to present a procedure to periodically update and assess the geohazard activity (volcanic activity, landslides and ground-subsidence) of a given area by exploiting the wide area coverage and the high co...

The BioLogos Foundation • www.BioLogos.org/projects/scholar-essays 1 In teaching at an evangelical liberal arts college that holds firmly to the inspiration and authority of Scripture, I find most of my students think the biblical doctrine of creation (DoC) is limited to two points: (1) God created out of nothing (ex nihilo) and (2) God created the world in six days (whatever they think “days” ...

A decade-long campaign to test the lunar cataclysm hypothesis continues to support an intense period of bombardment several hundred million years after solar system formation. Geological, geochemical, and isotopic data imply that (i) basin-forming impacts occurred on the Moon ∼4 Ga and (ii) impacts occurred on asteroids ∼3.6–4.1 Ga, implying the lunar cataclysm is actually an inner solar system...

BACKGROUND Nonattendance for scheduled appointments disturbs the effective management of pediatric pulmonary clinics. We hypothesized that the reasons for non-attendance and the necessary solutions might be different in pediatric pulmonary medicine than in other pediatric fields. We therefore investigated the factors associated with nonattendance this field in order to devise a corrective strat...

The Zermelo-Fraenkel axioms for set theory with the Axiom of Choice (ZFC) form the most commonly accepted foundations for mathematical practice, yet it is well-known that many mathematical statements are neither proved nor refuted from these axioms. One example is given by Gödel’s Second Incompleteness Theorem, which says that no consistent recursive axiom system which is strong enough to descr...

This paper will survey the various definitions of homology theories from the first Eilenberg-Mac Lane theories for group cohomology through the Cartan-Eilenberg attempt at a uniform (co-)homology theory in algebra, cotriple cohomology theories and the various acyclic models theorems that tied them all together (as much as was possible).
