Purpose: To examine the relationship of character strengths and quality of life (QOL) in persons with multiple sclerosis (MS). Specifically, this study examined the relationship of the 24 character strengths in Peterson and Seligman's model with QOL and three negative effects of MS (disability, fatigue, and depression). It also investigated whether the three negative effects of MS mediate the relationship of each of the character strengths and QOL.
Methods: Six hundred and twenty-four individuals with MS completed an online survey measuring character strengths, QOL, as measured by the Leeds Multiple Sclerosis Quality of Life Scale, disability, fatigue, and depression. SPSS was used to complete the correlational analysis, and Hayes' PROCESS macro for SPSS was used to conduct the mediation analyses.
Results: The strengths endorsed most frequently by the participants were honesty, kindness, and fairness. The least-endorsed strengths were self-regulation, zest, and spirituality. The strengths with the strongest association with QOL were zest, hope, and gratitude. Disability was not found to mediate any of the relationships between character strengths and QOL. Many of the character strengths were associated with QOL both directly and indirectly through fatigue and depression.
Conclusions: Many of the character strengths in the Peterson and Seligman model enhance QOL in persons with MS, both directly and through their influence on negative effects of MS. The results provide support for the development of character strengths interventions to impact QOL, both directly and indirectly through improvements to MS-related symptoms such as fatigue and depression.

Azuacenes, defined as azulene fused with acenes in a 6-7-5 ring topology and spanning lengths from 3 to 6 rings, have been synthesized using a new skeleton editing and [3 + 2] annulation synthesis protocol as a distinction regarding the procedures to obtain the 6-5-7 isomers. Comprehensive studies on ground-state and excited-state spectroscopy, electrochemical properties, chemical stability, and solid-state structure have been conducted to compare these azuacenes with acenes. For the same number of rings, we found that azuacenes improve the chemical stability of acenes (i.

Advances in the development of additive manufacturing materials (AM) and the low availability of studies on the impact response of AM specimens are the main reasons for this paper. Therefore, the influence of building orientation (vertical and horizontal) and the angle of the raster (15°/-75°, 30°/-60°, 45°/-45°, and 0°/90°) on the tensile and impact strength of AM specimens was investigated. The polylactic acid (PLA)-PolyMax, Mediflex and acrylonitrile-butadiene-styrene (ABS) filaments were chosen to provide a comprehensive characterization of AM materials with versatile mechanical properties.

An exotic quantum mechanical ground state, i.e. the nonmagnetic= 0 state, has been predicted for higher transition metal tsystems, due to the influence of strong spin-orbit coupling (SOC) or in other words, due to unquenched orbital moment contribution.

Using the QM/MM methodology and a local mode analysis, we investigated a character and a strength of FeS bonds of heme groups in oxidized and reduced forms of Bacterioferritin from Azotobacter vinelandii. The strength of the FeS bonds was correlated with a bond length, an energy density at a bond critical point, and a charge difference of the F and S atoms. Changing the oxidation state from ferrous to ferric generally makes the FeS bonds weaker, longer, more covalent, and more polar.

Diaryl thieno-[3,4-]thiophenes (TT) are photoswitchable compounds that operate through reversible photoinduced cyclization/cycloreversion and have been designed specifically for integration within π-conjugated polymers to switchably manipulate polymer electronic properties. Here we report on how cross conjugating the central TT moiety impacts photocyclization dynamics as interrogated using transient absorption spectroscopy (TAS) for a series of switches built with electron-rich substituents that have various electronic interaction strengths with the TT core. For cross-conjugated structures exhibiting a propensity to switch in steady-state photoconversion experiments, ultrafast TAS reveals signatures of rapid dynamics (occurring within <1-10 ps) similar to those observed for unsubstituted switches and that are consistent with photocyclization.
