Resolving the one-dimensional autonomous flow-free explosion problem
We introduce the explosion problem for semilinear elliptic and parabolic PDEs. The explosion problem is a question of existence of nonnegative solutions to −Lφ = λg(x, φ) and nonnegative global solutions to ∂tφ−Lφ = λg(x, t, φ). Under certain conditions there is a λ∗ > 0, called the explosion threshold, for which λ < λ∗ implies a solution exists, and λ > λ∗ implies no solution exists. In this p...

متن کاملHow honey kills bacteria.
With the rise in prevalence of antibiotic-resistant bacteria, honey is increasingly valued for its antibacterial activity. To characterize all bactericidal factors in a medical-grade honey, we used a novel approach of successive neutralization of individual honey bactericidal factors. All bacteria tested, including Bacillus subtilis, methicillin-resistant Staphylococcus aureus, extended-spectru...
متن کاملWhen Food Kills
F or the estimated 800 million people, living largely in developing countries, without enough food to eat, the main food risk is starvation. But if you ask, 'When does food actually kill?' in a country such as the United Kingdom, 'Not that often' is the short reply you would give after reading Hugh Pennington's book When Food Kills: BSE, E. coli, and Disaster Science. The two food-borne disease...
