To investigate conditions of silver electroless deposition on silicon (100), optical microscope, atomic force microscope (AFM) and attenuated total reflection infrared spectroscopy (ATR-FTIR) spectroscopy were used. Twenty second dipping in 0.8mM AgNO3/4.9% solution coats a silicon (100) wafer with a thin film of silver nanoparticles very well. According to AFM results, the diameter of silver particles is from 50 to 100nm. After deposition, arithmetic average of absolute values roughness (Ra) increased from ~0.7nm to ~1.2nm and the root mean square roughness (Rq) is from ~0.8nm to ~1.5nm. SCN- ions were applied to detect the existence of silver on silicon surface by ATR-FTIR spectroscopy and IR spectra demonstrate SCN- is a good adsorbent for silver metal. Patina is the general name of copper basic salts which forms green-blue film on the surface of ancient bronze architectures. Patina formation has been found on the surface of platinum or ruthenium after several scans of cyclic voltammetry in 2mM CuSO4/0.1M K2SO4, pH5 solution. Evidence implies that oxygen reduction reaction (ORR) triggers the patina formation. ORR is an important step of fuel cell process and only few sorts of noble metals like platinum can be worked as the catalyst of ORR. Mechanisms of patination involving …

Playing‐related pain is a common and serious problem among pianists. Information on cause and prevention is extremely limited due to a lack of scientific research. The purpose of this study was to (1) review and describe risk factors for piano‐related pain among college students and piano teachers that were reported in my previous two research studies, (2) justify the use of an ergonomically modified keyboard as a potential solution for reducing playing‐related pain, and (3) test and evaluate the effectiveness of an ergonomically modified keyboard for alleviating pianists' pain. Both study populations reported high prevalence rates for playing‐related pain: 86 % for college students (n = 35), 91 % for piano teachers (n = 47). For both populations, statistical analyses confirmed that pianists with small physical size (hand size) were more prone to pain. This finding helped rationalize the use of an ergonomically modified keyboard (the key width is 1/16 narrower than the standard) for small‐handed pianists as an ergonomic intervention. To test the effectiveness of an ergonomically modified keyboard, 35 college students played identical music on both the reduced-sized keyboard and the standard keyboard. Observations of video‐recorded performances revealed that small-handed pianists can avoid extreme stretching of their hands …

Past literature suggests that working mothers are at an increased risk for experiencing role strain compared to other employed adults. The current study investigated attitudes and beliefs of 783 working mothers of 15-month-old children using data from the National Institute of Child Health and Human Development's Study of Early Child Care and Youth Development. Working mothers' levels of role strain was associated with perceived social support, attitudes toward maternal employment, job and parental role quality, financial stress, and depression. Negative attitudes toward maternal employment predicted maternal separation anxiety, while positive attitudes toward employment did not affect separation anxiety. These findings have implications for the importance of decreasing role strain in working mothers.

Dan Beaty (1937-2002) was a prolific composer, pianist, researcher, educator, and writer. His large compositional output included chamber works, choral works, songs, orchestral pieces, electronic music, and keyboard works. Beaty was well versed in traditional Western music as well as the more avant-garde and perplexing idioms of the twentieth century. Beaty's compositions reflect the many fascinating, if not always popular, musical trends of his time. His music encompasses styles from serial to jazz, shows compositional influences from Arnold Schoenberg to Indonesian music, and demonstrates thought-provoking and highly intellectual craftsmanship. This document explores several of Beaty's songs through a discussion of the composer's life and compositional process. Songs included in this document are Three Weeks Songs, October, November, A Sappho Lyric, Love Song, That Night When Joy Began, and War Lyrics. This document was written to accompany the author's DMA Lecture-Recital at the University of North Texas. Unfortunately, Beaty's vocal music was never published and is mostly unknown. One goal of the project was to initiate interest in Beaty's songs. Through this document, Lecture-Recital, and additional performances, considerable strides have been made to bring Beaty's songs to new audiences throughout the United States. In addition, the author has received permission from …
