In what’s surely to be one of cultural highlights of the year, world-renowned pianists Tong-Il Han and Helen Lee have been lined up to perform two spectacular classical concerts in Florida. Playing host to the events, which take place on Saturday March 4th at 7pm, and Sunday March 5th, at 3pm, is The Chopin Project® with performances to be held at the Unitarian Universalist Church of Sarasota. It looks certain to be a full house with the concerts’ producer already witnessing demand from local music lovers and aficionados right across the State. Beginning with an all-Chopin solo piano recital by Han on the 4th, and concluding when Han is joined by his wife Helen, for a performance of an all-Schubert programme on the 5th, the weekend event will provide the public with an increasingly rare chance to hear Han, now 75 years old, play some of the most beautiful music ever composed for the piano. Han, a former child prodigy, Juilliard scholar, Leventritt prize winner (probably the most prestigious international competition for classical pianists) and White House pianist for President and Mrs. Kennedy, together with Lee, herself an eminent pianist and educator, was persuaded to perform once again by Frederick Slutsky, the brains behind The Chopin Project®. The Chopin Project®, a global community sharing information, educational, audio and video resources, and producing live concerts and outreach events, focused on the great composer’s works, makes Chopin’s music more accessible to listeners and music students worldwide. And, when Slutsky found out that such celebrated musicians lived nearby, he began working on a series of ideas that has culminated in the scheduled performances as well as a separate student outreach event at Sarasota’s Booker High School on Monday, March 6th where there’ll be a master class, performance and student question and answer session. Slutsky explains: “Han is a compelling figure in my life so I’m really excited that I and others are going to be able to hear him play in such an intimate venue. Not only am I fascinated by his background – being born in what is now North Korea, discovered by a 3-star American General and brought to the US at just 12, before winning his scholarship and then the Leventritt Prize at just 23 – but he is also responsible for some of the best Chopin recordings including his 24 Preludes 4 Ballades and 4 Scherzos.” “Getting to know Han, and his wife Helen, has been a real privilege and I just know that the two concerts we have lined up will be a real treat for those equally as passionate about the music as me. I’m sure the events will captivate everyone who attends from the casual fan, to fledgling music student, or even the most deeply committed Chopin or Schubert scholar. And I hope to be announcing more good news soon as Han and Helen are very interested in some larger outreach events that I’m currently working to produce.” Chopin Project® founder and producer, Slutsky, concludes: “Largely designed as a way to inspire and move the next generation of musicians and concert-goers – the main thrust of our stimulating outreach programs with voluntary associations, conservatory-trained musicians and local schools – these two concerts are being subsidised generously by local business clients, friends, and Chopin Project® patrons, so that students from Sarasota or Manatee County can attend both events free of charge together with one accompanying parent who will also benefit from free admission.” Anyone wanting tickets for these two exceptional Chopin Project® concerts, at the Unitarian Universalist Church of Sarasota, on the 4th and 5th of March, can click here to buy them online or call (800) 838-3006 to speak to a sales agent. Admission costs $30 for adults. Although now winding down commitments after a life of playing, recording and teaching all over the world, Tong-Il Han enjoys an enviable reputation. Not only is his personal story inspirational, but his list of musical credits is almost unparalleled. He has performed with the finest orchestras in the world, among them, in America, the New York Philharmonic, Chicago Symphony, Los Angeles Philharmonic, Cleveland Orchestra, and Detroit Symphony. He has also played with the London Philharmonic, Royal Philharmonic, Scottish National Orchestra, Oslo Philharmonic, Monte Carlo Orchestra, Rotterdam Philharmonic, Polish Radio National Orchestra, Budapest Radio Symphony Orchestra, Seoul Philharmonic Orchestra and Russian National Symphony, among many, many others. In a career spanning well over 50 years, Han has been a prolific recording artist, appeared regularly at many classical summer festivals and worked to improve the talents of young musicians: something he still enjoys doing with local students. He has taught music at Indiana University, Illinois State University, the University of North Texas and Boston University. He also served first as Dean of the College of Music and then as Chair Professor of Music at University of Ulsan in South Korea, as well as Guest Professor at Elisabeth University of Music in Hiroshima, Japan, and he has also taught at Korea’s Suncheon University. He now judges piano competitions worldwide. Helen Lee has studied piano performance with renowned musicians such as Leon Fleisher, Steven Bishop Kovachevich, James Tocco, Michel Block, Pamela Paul, and Vladimir Viardo. She received her Bachelor of Music degree from Indiana University, studying under a full scholarship, and her Master of Music from the University of North Texas, with a Teaching Fellowship. Her concert career covers cities in the USA, Korea, Hong Kong, Japan, Thailand, Singapore and Mexico, including as a guest soloist with the Seoul Juenesse Orchestra, the University of North Texas Orchestra, the Hong Kong Philharmonic Orchestra and Daegu Philharmonic Orchestra. Lee taught as the National Institute of Education in Singapore for 14 years, and Nanyang Technological University for 5 years before her return to Korea in 2009, where she taught at Gwangju University. In addition to her musical career, she is also an award-winning artist having won an international painting competition in 2005 and having had her works shown all over the world.

This paper proposes a method to optimize both the total cost and order fill rates in a supply chain using the particle swarm optimization (PSO) method. This method automatically adjusts the initial inventory levels of all tiers involved in a supply chain by considering information quality level (IQL), which is determined by the degree of availability of lead time history data. Analyses of variance are used to examine if there are any effects of IQL on the total cost and order fill rates. The results show that the proposed method finds better solutions which provide a lower inventory level while maintaining higher order fill rates than when PSO is not applied. © 2013 Springer-Verlag London.

The unexpected formation of supramacromolecules of β-cyclodextrin in aqueous solution under ambient conditions is reported in this article. The shape and size of the supramacromolecules could be controlled by varying the stirring time and the concentration. The supramolecular interactions of the supramacromolecules were confirmed by 1H NMR spectroscopy. Additionally, visual evidence of the supramacromolecules was provided by transmission and scanning electron microscopy. The thermal behavior of the supramacromolecules was examined by thermogravimetric analysis. The molecular mass determination by gel permeation chromatography showed that the supramacromolecules had a high molar mass. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Polymer nanoparticles have attracted the interest of many research groups and have been utilized in an increasing number of fields during the last decades. Generally, two main strategies are employed for their preparation: the dispersion of preformed polymers and the polymerization of monomers. Various techniques can be used to produce polymer nanoparticles, such as solvent evaporation, salting-out, dialysis, supercritical fluid technology, micro-emulsion, mini-emulsion, surfactant-free emulsion, and interfacial polymerization. The choice of method depends on a number of factors, such as, particle size, particle size distribution, area of application, etc. This review covers the general description of the preparation of polymer nanoparticles and the detailed description of the crucial parameters involved in techniques designed to obtain the desired properties. © 2011 Elsevier Ltd.

A simple, green, one-pot synthesis of gold nanoparticles was achieved through the reaction of an aqueous mixture of potassium tetrachloroaurate(III) and the macrocycle cucurbit[7]uril in the presence of sodium hydroxide at room temperature without introducing any kind of traditional reducing agents and/or external energy. The as-prepared gold nanoparticles showed catalytic activity for the reduction reaction of 4-nitrophenol in the presence of NaBH 4, which has been established by visual inspection and UV/Vis spectroscopy. This report is the first for the preparation of gold nanoparticles using cucurbit[7]uril in aqueous media through chemical reduction without employing conventional reducing agents and/or external energy. © 2010 Wiley-VCH Verlag GmbH & Co.

The selective catalyst reaction technology was stipulated under the IMO Tier 3 regulation for controlling NOx emissions from marine diesel engines. This paper presents a steady kinetic model of urea-SCR with a vanadium-based catalyst. Simulation was carried out using a commercial one-dimensional aftertreatment code coupled with an optimizer. Optimization was performed using experimental NH3 temperature programming desorption (TPD) data. The simulated data and trends in NH3 and NOx reactions under different temperatures, NO/NO2 ratios, space velocities and NH3/NOx ratios produced generally good agreement with experimental measurements. At increased space velocities, the NOx and NH3 reaction rates decreased, but this had no effect on the NOx conversion rate until over 400 °C. Over 450 °C, the NH3 oxidation of ammonia was equal to the NOx conversion rate due to NH3 oxidation. Based on these results, an optimal condition was proposed for urea-SCR in terms of NH3/NOx ratio and temperature. In the case of NH3/NOx = 0.8, the NOx conversion rate was 80% and NH3 slip was no occur over 200 °C. The optimal NOx conversion condition for these two performance indicators is estimated to be NH3/NOx = 0.8-1.0 at 300 °C. © 2016 Elsevier Ltd. All rights reserved.

The upregulatory mechanism of cellular NF-κB activity by carcinogens, N-nitroso-N-methylurea (NMU) and N-nitroso-N-ethylurea (NEU) in human malignant keratinocytes was investigated. To elucidate the role of protein kinase C (PKC) in the upregulation of NF-κB by NMU and NEU, two known PKC inhibitors, staurosporine and H-7 were studied. Treatment of cells with PKC inhibitors decreased NF-κB activity in a dose responsive manner at concentrations of 20 ∼ 200 nM. Staurosporine (160 nM) and H-7 (200 nM) downregulated the cellular NF-κB activation up to 20 and 60% compared to the NF-κB activity that was upregulated by NMU (5 μM) and NEU (5 μM), respectively. These results indicated that the PKC activity was responsible for the upregulation of NF-κB activity. The level of phosphorylation of I-κBα, the predominant form of the I-κB family represented by NMU and NEU, was quantified. The relative amount of I-κBα phosphorylation (serines-32 and -36) determined using the cellular activation of signaling ELISA assay method showed that NMU (5 μM) and NEU (5 μM) increased the amount of I-κBα phosphorylation up to 17 and 10% compared to the control, respectively. The results demonstrate the upregulatory effect of NMU and NEU on cellular NF-κB activity in human keratinocytes via the protein kinase C-mediated pathway. © 2010 The Pharmaceutical Society of Korea and Springer Netherlands.

Acrolein, a reactive electrophilic α, β-unsaturated aldehyde, is known to be an alkylating chemical carcinogen. The effect of acrolein on the activation of NF-κB in human malignant epidermal keratinocytes was examined to elucidate the molecular mechanism associated with this NF-κB-acrolein regulation and its consecutive sequence, nitric oxide (NO) production. Acrolein significantly downregulated the cellular NF-κB activity up to 60% compared with control as well as the lipopolysaccharide (LPS)-induced NO production in a dose response manner at concentrations of 10~30 μM. To investigate the regulatory mechanism associated with this NF-κB-acrolein downregulation, the relative level of phosphorylation of I-κBα (serines-32 and -36), a principle regulator of NF-κB activation, represented by acrolein, was quantified. Acrolein inhibited NF-κB activity without altering cellular levels of the phosphorylated and nonphosphorylated forms of I-κBα, implying that the downregulatory effect of acrolein on cellular NF-κB activity in human skin cells is an I-κBα-independent activation pathway. The results suggests that acrolein causes the decrease in nitric oxide production as an I-κBα-independent downregulator of NF-κB activity in human malignant keratinocytes, and acrolein-induced carcinogenesis may be associated with the modulation of cellular NF-κB activity. © 2010 Springer-Verlag.
