Β-Thujaplicin: A Soil Antifungal, Dennis J. Baumgardner

Dennis J. Baumgardner, MD

Background: β-thujaplicin (β-Th), also known as hinokitiol, naturally occurs in cedar mulch, is found in personal care products and has in vitro antitumor activities. It is antibacterial and antifungal, but has not been tested on soil. Scedosporium apiospermum (Sce) is an emerging “extremophile” fungal pathogen found in built outdoor environments. Purpose: Pilot β-Th as “natural” soil antimicrobial or for isolation of extremophiles, and to explore β-Th resistance as selective advantage to Sce in mulched landscape. Methods: A variety of outdoor and indoor environments were used for 2 sets of 24 paired soil samples. Soil/H20 slurry (0.1 ml) was spread on …

An Evaluation Of The Us High Production Volume (Hpv) Chemical-Testing Programme: A Study In (Ir)Relevance, Redundancy And Retro Thinking, Andrew Nicholson, Jessica Sandler, Troy Seidle

Troy Seidle, PhD

Under the US Environmental Protection Agency (EPA) High Production Volume (HPV) Challenge Programme, chemical companies have volunteered to conduct screening-level toxicity tests on approximately 2800 widely-used industrial chemicals. Participating companies are committed to providing available toxicity information to the EPA and presenting testing proposals for review by the EPA and posting on the EPA Web site as public information. People for the Ethical Treatment of Animals (PETA) and a coalition of animal protection organisations have reviewed all the test plans submitted by the participating chemical companies for compliance with the original HPV framework, as well as with animal welfare guidelines …

Environews #1, Richard B. Philp

Richard B. Philp

Environews #1 is, hopefuly, the first of a series dealing with current issues of environmental concern. This issue discusses the possible role of climate change in the massive floods that followed hurricane sandy, depletion of the world's fish stocks, the possible role, bothe positive and negative, of aquaculture, and the trend to seek oil in increasingly environmentally dangerous venues.

Experimental Validation Of The Multiple-Zone System Ventilation Efficiency Equation Of Ansi/Ashrae Standard 62.1 (1276-Rp), David P. Yuill, Grenville K. Yuill, Andrew H. Coward

David Yuill

This article describes an experiment that was carried out on an existing building to test the validity of the system ventilation efficiency equation for multiple-zone recirculating systems of ANSI/ASHRAE Standard 62.1. The system ventilation efficiency equation (SVEE) can be applied to buildings that use a recirculating air distribution system. It accounts for the fact that the return air carries some “unused” outdoor air, so that the amount of new outdoor air introduced at the air handler can be reduced. The SVEE is based on a mass balance but infiltration and interzonal mixing are not included in the formulation. Since infiltration …

Spatial Distribution Of Commercial Banks In Ilorin Metropolis, Kwara State, Nigeria, I B. Abdullahi, M A. Ijaiya, A Abdulraheem, R I. Abdulkadir, R O. Ibrahim

Confluence Journal of Environmental Studies (CJES), Kogi State University, Nigeria

The spatial distribution of banks in any geographic entity determines the level of accessibility to its services by the public. This study examined the pattern of banks distribution in Ilorin metropolis. Field survey was employed in determining the number of available commercial banks and their respective distances between each other. The spatial analysis technique such as the nearest neighbour analysis as used ascertain the degree of clustering, density and the average distance taken to access these services. The study revealed that about 96% of the total number of banks are situated in the Central Business District which exhibited a very …
