A short-time exposure on the concentration--time relationship base, a classification of substances according to the degree of hazard and the program for assessing safety coefficients have been suggested in order to predict the basic toxicometric parameters (chronic exposure thresholds, maximum allowable concentrations, safety coefficients, and others).

Cultivating Awareness and Resilience in Education (CARE for Teachers) is a mindfulness-based professional development program designed to reduce stress and improve teachers’ performance and classroom learning environments. A randomized controlled trial examined program efficacy and acceptability among a sample of 50 teachers randomly assigned to CARE or waitlist control condition. Participants ...

Many of us go through our daily lives on autopilot, not fully aware of our conscious experiences. In a discussion moderated by Steve Paulson, executive producer and host of To the Best of Our Knowledge, neuroscientists Richard Davidson and Amishi Jha and clinical mindfulness expert Jon Kabat-Zinn explore the role of consciousness in mental and physical health, how we can train our minds to be m...

Official Circular 198 (Ruehle and Brewer, 1931) gives directions for performing the agar cup-plate test. However, in the limited literature dealing with the subject, no mention is made of the influence of varying the volume of agar, the amount of inoculum, the hydrogen ion concentration or other factors. In the course of other studies with the agar cup-plate method (Rose and Miller, 1939; Mille...

A static correlation function of concentration fluctuations in a (dilute) binary liquid mixture subjected to both a concentration gradient and uniform shear flow is investigated within the framework of fluctuating hydrodynamics. It is shown that a well-known |c|(2)/k(4) long-range correlation at large wave numbers k crosses over to a weaker divergent one at wave numbers satisfying k<(gamma;/D)(...

This study validates the Persian version of the Langer Mindfulness Scale (LMS). The original scale consists of 21 items and 4 subscales; namely, novelty producing, novelty seeking, engagement, and flexibility. In this study, four samples including 2271 individuals in total participated. Confirmatory factor analysis was employed to test the factorial structure of the Persian version. The results...

Two studies examined the role of mindfulness in romantic relationship satisfaction and in responses to relationship stress. Using a longitudinal design, Study 1 found that higher trait mindfulness predicted higher relationship satisfaction and greater capacities to respond constructively to relationship stress. Study 2 replicated and extended these findings. Mindfulness was again shown to relat...
