Multi axes vibration fixtures
A simplified technique and apparatus are described for testing the effects of vibration on various material specimen. Particular attention was given to tests along the orthogonal vibrational planes in order to prove the strength of the item under extraordinary conditions to which it will be subjected
\u3csup\u3e13\u3c/sup\u3eC NMR Analysis of Biologically Produced Pyrene Residues by \u3cem\u3eMycobacterium\u3c/em\u3e sp. KMS in the Presence of Humic Acid
Cultures of the pyrene degrading Mycobacterium sp. KMS were incubated with [4-13C]pyrene or [4,5,9,10-14C]pyrene with and without a soil humic acid standard to characterize the chemical nature of the produced residues and evaluate the potential for bonding reactions with humic acid. Cultures were subjected to a “humic acid/humin” separation at acidic pH, a duplicate separation followed by solvent extraction of the humic acid/humin fraction, and a high pH separation. 13C NMR analysis was conducted on the resulting solid extracts. Results indicated that the activity associated with solid extracts did not depend on pH and that approximately 10% of the added activity was not removed from the solid humic acid/humin fraction by solvent extraction. 13C NMR analysis supported the conclusion that the majority of pyrene metabolites were incorporated into cellular material. Some evidence was found for metabolite reaction with the added humic material, but this did not appear to be a primary fate mechanism
Psychological impact of identifying character strengths in people with psychosis
A one group pre-post test design investigated the impact of identifying character strengths using the Values In Action Inventory of Strengths (VIA-IS) with individuals with early psychosis (N = 29). Post-test improvements in positive affect and cognitive performance were observed. Neither self-esteem nor self-efficacy improved. The technique appears feasible for use within early intervention services. Adverse consequences should be monitored and additional components considered to enhance benefits

Willpower and Ego-Depletion: How I Do What I Don’t Want to Do, and Why It’s Not (Completely) My Fault When I Don’t
Experimental studies on willpower confirm the Strength Model of Self-Control, which claims that willpower depends on limited physiological resources. Exercising willpower depletes these resources, which impairs further exercises of willpower. This phenomenon is called “ego-depletion.” As a result, depleting these resources impairs further exercises of executive control. My thesis argues that this phenomenon has two important philosophical consequences: First, ego-depletion provides evidence against the Humean approach to motivation, according to which people always act according to their strongest desires. Second, people suffering from ego-depletion are not fully responsible for failures of self-control
