Adoption Process for the Model Aquatic Health Code: An Example
Get PDFIn 2014 the U.S. Centers for Disease Control and Prevention (CDC) published the first edition of the Model Aquatic Health Code (MAHC). This document represented the inaugural introduction of a federal policy guideline with a direct focus in the area of aquatic venue operation and maintenance with the sole purpose of improving the nature of public health in the field. The Indiana State Department of Health (ISDH) began the review and adoption process soon after the policy’s release. The ISDH process is proposed as one method for others to consider. The background and history of the MAHC are presented in this manuscript along with an overview of the adoption process to date that has been employed by the State of Indiana. In addition, information is provided on the Diffusion of Innovations Theory (DIT) as a possible method for assessing the long-term adoption of the MAHC on a national level
The supernatural characters and powers of sacred trees in the Holy Land
Get PDFThis article surveys the beliefs concerning the supernatural characteristics and powers of sacred trees in Israel; it is based on a field study as well as a survey of the literature and includes 118 interviews with Muslims and Druze. Both the Muslims and Druze in this study attribute supernatural dimensions to sacred trees which are directly related to ancient, deep-rooted pagan traditions. The Muslims attribute similar divine powers to sacred trees as they do to the graves of their saints; the graves and the trees are both considered to be the abode of the soul of a saint which is the source of their miraculous powers. Any violation of a sacred tree would be strictly punished while leaving the opportunity for atonement and forgiveness. The Druze, who believe in the transmigration of souls, have similar traditions concerning sacred trees but with a different religious background. In polytheistic religions the sacred grove/forest is a centre of the community's official worship; any violation of the trees is regarded as a threat to the well being of the community. Punishments may thus be collective. In the monotheistic world (including Christianity, Islam and Druze) the pagan worship of trees was converted into the worship/adoration of saints/prophets; it is not a part of the official religion but rather a personal act and the punishments are exerted only on the violating individual
Consensus guidelines for the use and interpretation of angiogenesis assays
Get PDFThe formation of new blood vessels, or angiogenesis, is a complex process that plays important roles in growth and development, tissue and organ regeneration, as well as numerous pathological conditions. Angiogenesis undergoes multiple discrete steps that can be individually evaluated and quantified by a large number of bioassays. These independent assessments hold advantages but also have limitations. This article describes in vivo, ex vivo, and in vitro bioassays that are available for the evaluation of angiogenesis and highlights critical aspects that are relevant for their execution and proper interpretation. As such, this collaborative work is the first edition of consensus guidelines on angiogenesis bioassays to serve for current and future reference
The Mass of Kepler-93b and The Composition of Terrestrial Planets
Get PDFKepler-93b is a 1.478 +/- 0.019 Earth radius planet with a 4.7 day period
around a bright (V=10.2), astroseismically-characterized host star with a mass
of 0.911+/-0.033 solar masses and a radius of 0.919+/-0.011 solar radii. Based
on 86 radial velocity observations obtained with the HARPS-N spectrograph on
the Telescopio Nazionale Galileo and 32 archival Keck/HIRES observations, we
present a precise mass estimate of 4.02+/-0.68 Earth masses. The corresponding
high density of 6.88+/-1.18 g/cc is consistent with a rocky composition of
primarily iron and magnesium silicate. We compare Kepler-93b to other dense
planets with well-constrained parameters and find that between 1-6 Earth
masses, all dense planets including the Earth and Venus are well-described by
the same fixed ratio of iron to magnesium silicate. There are as of yet no
examples of such planets with masses > 6 Earth masses: All known planets in
this mass regime have lower densities requiring significant fractions of
volatiles or H/He gas. We also constrain the mass and period of the outer
companion in the Kepler-93 system from the long-term radial velocity trend and
archival adaptive optics images. As the sample of dense planets with
well-constrained masses and radii continues to grow, we will be able to test
whether the fixed compositional model found for the seven dense planets
considered in this paper extends to the full population of 1-6 Earth mass
planets.Comment: 8 pages, 4 figures. Accepted for publication in Ap
