The use of photograms provides a permanent record of microbiological assays in which diffusion of a substance in agar is measured. The accuracy of this procedure is comparable to direct measurement. This technique is inexpensive, does not require special photographic equipment, and is applicable to many tests commonly employed in clinical microbiology and immunology laboratories.

Human activities have released large amounts of toxic organic and inorganic chemicals into the environment. Toxic waste streams threaten dwindling drinking water supplies and impact terrestrial, estuarine and marine ecosystems. Cleanup is technically challenging and the costs based on traditional technologies are exceeding the economic capabilities of even the richest countries. Recent advances...

Microbiology is a relatively modern scientific discipline intended to objectively study microorganisms, including pathogens and nonpathogens. However, since its birth, this science has been negatively affected by anthropocentric convictions, including rational and irrational beliefs. Among these, for example, is the artificial separation between environmental and medical microbiology that weake...

My long-term goals are to advance understanding of sediment transport processes. In this context, the long-term goal of this project is to advance understanding of the reference concentration, i.e. concentration of suspended sediments at a small distance above the seafloor. The scientific interest is in relating this reference concentration to the forcing conditions of waves and currents. The n...

This study compares the scope and nature of the gang problem in two communities: one in the United States and one in Trinidad and Tobago, a small-island developing state in the eastern Caribbean that has experienced a serious outbreak of violence over the past decade. Data drawn from surveys of adult arrestees reveal that among respondents, 3.2% of those in the U.S. sample and 5.1% of those in ...

OBJECTIVES This article reports the prevalence of two types of interpersonal violence (IPV) (sexual and physical) and one type of aggression (psychological) in three low-to-middle-income Caribbean countries. It examines IPV among adolescents and young adults as both victims and perpetrators. METHOD This population-based study compares the experiences of 15-30 year olds in countries at differe...
