Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links

open access: yesGeophysical Monograph Series, Page 191-228., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

A Risk-Based Framework for Ranking Microbiological Hazards and Identifying Mitigation Strategies for Dried Fruits, Vegetables, Herbs, and Spices Used in Ready-to-Eat Foods. [PDF]

open access: yesCompr Rev Food Sci Food Saf
ABSTRACT Low water activity ingredients, including dried fruits, vegetables, herbs, and spices, are widely used in ready‐to‐eat (RTE) and non‐RTE foods. Although low water activity limits microbial growth, bacterial pathogens can survive for extended periods in these products.
