ABILITY TO MAINTAIN AMPLITUDE WHILE PERFORMING CIRCLES ON POMMEL HORSE

Amplitude is an important aspect for performing circles on a pommel horse, but the ability to maintain such amplitude over the course of a long performance, say, over 10 seconds, has not been studied. This study provides pilot data for the ability to perform many circles and maintain amplitude. In all, 28 gymnasts performed as many circles as possible on a pommel horse while maintaining as great an amplitude as possible. Kinematic data were recorded using a Kinect set above the pommel horse, and the head–toe distance on a horizontal plane was computed as an amplitude variable. As a result, the average number of circles was 46; only 25% of participants were able to perform over 50 circles. Even for them, it was difficult to maintain amplitude after 50th repetitions, suggesting that 50 circles was a discriminative number for higher-level performance

(−)545-fac-Δ-Tris(l-prolinato)cobalt(III) trihydrate

The absolute configuration of the octa­hedral fac-CoN3O3 title complex, [Co(C5H8NO2)3]·3H2O, has been determined by single-crystal X-ray analysis. A three-dimensional network of hydrogen bonds is observed between the proline carboxyl­ate groups and the three uncoordinated water mol­ecules

Pyrene-Modified Cyclic Peptides Detect Cu2+ Ions by Fluorescence in Water

The detection of metal ions is an option for maintaining water quality and diagnosing metal ion-related diseases. In this study, we successfully detected metal ions using fluorescent peptides in water. First, we prepared seven linear (L1-L7) and seven cyclic (C1-C7) peptides containing two pyrenyl (Pyr) units and assessed the response to various metal ions by fluorescence. The results indicated that C1, which contains a hexameric cyclic peptide moiety consisting of Pyr and Gly units, did not show a fluorescent response to metal ions, while the linear L1 corresponding to C1 showed a response to Cu2+, but its selectivity was found to be poor through a competition assay for each metal ion. We then assessed C2-C7 and L2-L7, in which Gly was replaced by His units at various positions in the same manner. The results showed that C2-C7 responded to Cu2+ in a manner dependent on the His position. Additionally, superior selectivity was observed in C7 through a competition assay. These results demonstrate that the structural restriction of peptides and the sequence affect the selective detection of Cu2+ and reveal that peptides with an appropriate structure can accomplish the fluorescent detection of Cu2+ specifically

シュウキョウガ ノ カンショウ キョウイク カツドウ ニ ノゾム : ソノ ケイカク ウンエイ ト タントウ ガクセイ ノ ヘンカ

In 2009, we held an educational art workshop on stories from the Old Testament at the Otsuka Museum of Art in Naruto City. This workshop is one of the activities of N＊CAP（Naruto Children’s Art Park）. The purpose is for local children to become more familiar with and appreciate the art. During this activity, children showed interest towards the paintings related to biblical stories and showed no reluctance towards them, which was our initial concern. However there is some room for improvement such as increasing the motivation of the university students and allocating time properly for children to be focused throughout the workshop. These are the main points that can be improved. Using the improvement points from the 2010 workshop, we held another activity using the theme of the New Testament. This time, our coordinator only gave the university students the theme and let them delegate the activities. They let two students who were in charge of organizing the event handle all matters. These students improved the plan with their classmates taking into consideration previous workshops and carried out the plan on their own. They held a craft workshop making pseudo stained glass using vinyl sheets which is safer and easier for children to use. In this workshop, children showed no sign of fatigue, and enjoyed doing the crafts very much while completing work of their own. The high motivation of the students led to the success of this workshop. One of the benefits of this workshop is that the students were able to appreciate the paintings with a deeper perception. They are now able to seek out small details of biblical paintings of the Medieval Gothic Period and cherish the meanings of them.

A new catechin oxidation product and polymeric polyphenols of post-fermented tea

A new epicatechin oxidation product with a 3,6-dihydro-6-oxo-2H-pyran-2- carboxylic acid moiety was isolated from a commercially available post-fermented tea that is produced by microbial fermentation of green tea. The structure of this product was determined by spectroscopic methods. A production mechanism that includes the oxygenative cleavage of the catechol B-ring of (-)-epicatechin is proposed. In addition, polymeric polyphenols were separated from the post-fermented tea and partially characterised by 13C NMR spectroscopy and gel-permeation chromatography. The polymers appear to be primarily composed of epigalloacetechin-3-O-gallate and the molecular weight (Mn) of the acetylated form was estimated to be ∼3500
