The reaction of mesitylene with ethyl propiolate in the presence of [Pd(dppe)(OAc)2] in TFA at 30 °C for 5 h gave diethyl (2E,4Z)-4-[(2,4,6-trimethylphenyl)methylene]-2-pentenedioate selectively. Screening several bidentate phosphines ligands showed that dppe and dppm ligands are good for the arylbutadiene formation. This reaction was applied to other electron-rich arenes and found to be effective for synthesis of arylbutadienes and extended π-conjugated molecules. The regio- and stereoselective addition of an arene to propiolate was confirmed by NMR and single-crystal X-ray structural analyses of the products, suggesting that the arylbutadiene formation consisted of anti addition of an arene and a metal to the triple bond of ethyl propiolate, followed by syn addition to another molecule of ethyl propiolate. Similarly, the reaction of various arenes with ethyl propiolate in the presence of [Pt(dppe)(OTf)2] catalyst gave arylbutadienes selectively. In the Pd- or Pt-catalyzed reaction of arenes with ethyl propiolate, it was found that a bidentate ligand controlled the reaction to lead the formation of arylbutadienes.

[Ru(tpy)(picSO)]BF4 (tpy: 2,2′:6′,2′′-terpyridine, picSO: 6-[(methylsulfinyl)methyl]picolinate) undergoes profound linkage isomerization behavior between stable S-bound and metastable O-bound isomers. S-[RuII(tpy)(picSO)]BF4 experiences photoisomerization to O-[RuII(tpy)(picSO)]BF4 upon irradiation with 436 nm light, whereas the back reaction is triggered with 546 nm light. Electrochemical linkage isomerization also takes place.

Effects of ferrous ions on the growth and activity of sulfate-reducing bacteria (SRB) have been investigated using biological and analytical techniques for a better understanding of its metabolism in corrosive media with high contents of metal ions. In-situ gravimetry by the quartz crystal microbalance (QCM) technique was also applied to examine the sulfide-producing process in the medium. The growth of SRB increased with increasing ferrous ion concentration up to 0.01M and retarded above 0.01M. In the low concentration region (0.00036M-0.01M) ferrous ions enhanced the growth of SRB, whereas in the high concetration region (0.03M-0.7M) ferrous ions gave the opposite effect due to high osmotic pressure. The FeS producing ability was closely related to the growth of bacteria, therefore it seems that SRB accelerates the corrosion of metal in the medium including 0.01M ferrous ions. QCM technique was able to detect sensitively the amount of FeS attached on the electrode surface, which was proportional to the total amount of FeS in the medium. Thus it was found that QCM technique is powerful for monitoring the FeS producing process.

Launeddas is a Sardinian triple-clarinet. There are now nine types of Launeddas, each in a different mode. The main repertoire of launeddas is dance music. Its improvisatory performance is based on the compositional principle iskala, a series of pikkiada groups (an individual pikkiada consists of periods of six or nine measure) whose selection and order is aesthetically determined. Each of the nine types of launeddas has its own iskala.The existing studies have failed to differentiate between the theory of iskala and its performance practice. Through the course of fieldwork I hoped to develop a theory that would support iskala performance practice. From my fieldwork I have discovered that that the concept of iskala varies between regions, generationsand players, I decided to concentrate on the repertory of Aurelio Porcu (1915-), one of the oldest of the current generations of performers. Porcu's tradition derives from the Sarrabus, central region of launeddas playing. His repertory was inherited from his masters, some of the greatest launeddas performers. Porcu devoted his life career to a professional launeddas performance. As heir to one of the central launeddas traditions, analysis and understanding of his performance and repertory is vital.Through analyzing the structural characteristics of iskala, this thesis attempts to clarify the aesthetic process underlying iskala performance.Analysis revealed the following three points, as follows. First, the pikkiada groups that form the iskala, is are arranged according to the dance. Although the selection of pikkiada varies according to iskala, two pikkiada groups emerged as common to all iskala performance; furias and pass'appuntau, both of which are related to dance steps. It can consequently be said that the structure of iskala performance mirrors the structure of the dance ‹opening→furias→pass'appuntau→end›.Second, in performance, there appear two characteristic features of the iskala. The first of these is what I refer to as “flexible framework”. This refers to the length of performance. As launeddas players decide on the spur of the moment how to develop pikkiada groups, they can control the length of performance, making it as long or short as necessary.Furthermore, according to Porcu there is an aesthetic principle that no pikkiada group shall be repeated, what I refer to as a “one way principle”. This is a somewhat contradictory principle for launeddas players urged to play long performance. The existence of the “one way principle” demonstrates that launeddas dance music, based on a concept of the iskala, is a well-ordered logical construction.Third, there appears to be an ideal “pikkiada matrix” for each of the pikkiada groups. When Porcu teaches iskala, he demonstrates various sequences of pikkiada in each group (Porcu calls each pikkiada group merely “sa pikkiada”, i. e the pikkiada). These are regarded as examples of typical pikkiada, in which there is no fixed or privileged pikkiada like theme, contrary to the explanation in the former studies. In the performance launeddas players can freely decide and play various versions of pikkiada in each group providing they follows the proper pattern at each stage of the hierarchy (motif, phrase, and whole pikkiada of each group). While this is not a concrete pattern that players are bound to adhere to, it appears that this has been extracted as a successful model of performance by experienced launeddas players. As a result, performing launeddas dance music can be interpreted as cr

In South-Sardinian public round dance, traditionally accompanied by launeddas or indigenous triple-clarinet, the dancers have emphasized an aesthetical value with the expression, “to dance according to the music.” This article argues how the dancers make out or recognize the music and choose their steps, clarifying the dynamic correlation between dance and music in the launeddas dance. As part of my fieldwork, an analysis was done of dance steps of Ierzu village, and revealed that the foregoing aesthetical judgment implies the following three points; metrical synchronization between dance and music, selection of steps appropriate to the pichiada, melody-type based on which various phrases will be improvised, and change of step with the transition of one pichiada to the following. The launeddas dance and the music have been inseparably developed in public dance circles. Their reciprocal structure characterizes the performance; the dancers choose steps following the music while the musician varies his performance seeing the dancers' condition or demands. The interaction between dancers and musician, sometimes conversational sometimes competitive, makes the performance dynamic and entertaining. It is this dynamism that makes the launeddas dance artistic.

Objective: We analyzed articles in the Japanese Journal of Drug Informatics with the goal of identifying recent research trends in drug informatics.Method: The appearance frequencies of keywords in the Japanese Journal of Drug Informatics (2001: vol. 3 (1) to 2009: vol. 11 (4)) and Japanese Journal of Pharmaceutical Health Care and Sciences (2009: vol. 35 (1) to (6)), and words in abstracts in Japanese Journal of Drug Informatics (2009: vol. 11 (1) to 2010: vol. 12 (4)) were analyzed. Results: To investigate keywords in the Japanese Journal of Drug Informatics, appearance frequencies of information, drug, drugs and pharmacist in 2001: vol. 3 (1) to 2003: vol. 5 (4), those of information, drug, drugs, medical, medication and questionnaire in 2004: vol. 6 (1) to 2006: vol. 8 (4), and those of information, drug, questionnaire, survey, pharmacist, adverse and generic in 2007: vol. 9 (1) to 2009: vol. 11 (4) were higher than those of other keywords.  In the Japanese Journal of Pharmaceutical Health Care and Sciences, appearance frequencies of drug, pharmacy, care, patient, pharmaceutical, cancer, education, training, analysis and drugs were higher than those of other keywords.  Information, drug(s), patients, pharmacists, hospital, use, questionnaire, medical, adverse, survey, agents, generic and pharmaceutical were high frequency words used in abstracts published in the Japanese Journal of Drug Informatics.  These words in abstracts indicate a Zipf’s law-like rank distribution.  Co-occurrence network graphs using abstracts showed that the first cluster consisted of medical, drug, adverse, drugs, pharmaceutical, hospital, doctors, contents and drug around information and pharmacists as hubs, and the second cluster consisted of 3 words (agents, woman and pregnant).  Furthermore, co-occurrence network graphs indicated that care, medical, pharmaceutical, information, adverse, pharmacists, hospital, doctors, questionnaire, woman, pregnant, package and side were matters of important arguments and/or phenomena.Conclusion: These data suggest that the scope of themes in articles published in the Japanese Journal of Drug Informatics is establishing definitive categories.  The recent themes and contents of the Japanese Journal of Drug Informatics were closely and mutually related.

Stability of fucoxanthin was assessed in dried Undaria pinnatifida (wakame). After 210 days storage of dried wakame in the dark at 50°C, the stability of fucoxanthin was higher than that of purified fucoxanthin incubated at both 20°C and 40°C. Furthermore, we analyzed the stability of fucoxanthin in scones containing 0.5 − 2 wt% commercial dried wakame powder. More than 85% of the fucoxanthin remained unchanged in the scones after heating the dough at 190°C for 30 min. Sensory analysis indicated that although the addition of wakame powder darkened the appearance and strengthened both the taste and smell of the scones, they remained acceptable. Furthermore, overall sensory scores showed that scones containing 0.5 wt% and 2 wt% wakame powder were more favorable than control scones.

Reverse phase high performance liquid chromatography (HPLC) was used as a rapid means of monitoring the erythromycin and the tetracycline fermentation processes. The sample preparation process for tetracycline in the fermentation broth includes simple dilution and filtration through a Millipore filter prior to injection into the HPLC column. Fermentation broth samples showed no interference, and excellent separation for selective determination of tetracycline, 4-epitetracycline, anhydrotetracycline, chlortetracycline, and 4-epianhydrotetracycline was obtained. The relative standard deviation for the HPLC analysis for tetracycline is about one percent and the correlation coefficient between the HPLC and the spectrophotometric assay methods is better than 0.994.The sample preparation procedure for erythromycin determination in fermentation broth requires solvent cleanup and extraction processes. The chromatographic analysis takes approximately 25 minutes, and the HPLC method is capable of separating and quantifying erythromycins A, B, C, and various epimers and degradation compounds. The correlation coefficient between the HPLC and the microbiological assay method is 0.970.

An experimental investigation is carried out for natural-convection heat transfer to air from an array of five cylinders which are arranged in an inclined plane. The heat transfer coefficient of each cylinder in the array and the average heat transfer coefficient of the array are obtained for a variety of combinations of cylinder spacing, cylinder surface temperature and array inclination angle.A correlation equation for the average heat transfer coefficient of the vertical array is proposed. A method for estimating the heat transfer coefficient of each cylinder in the array is also given. Application of these results and the previously proposed heat transfer correlations for the horizontal array shows good agreement with the heat transfer coefficient of each cylinder in the inclined array.

With developments in optical imaging over the past decade, statistical methods for estimating dendritic membrane resistance from observed noisy signals have been proposed. In most of previous studies, membrane resistance over a dendritic tree was assumed to be constant, or membrane resistance at a point rather than that over a dendrite was investigated. Membrane resistance, however, is actually not constant over a dendrite. In a previous study, a method was proposed in which membrane resistance value is expressed as a non-constant function of position on dendrite, and parameters of the function are estimated. Although this method is effective, it is applicable only when the appropriate function is known. We propose a statistical method, which does not express membrane resistance as a function of position on dendrite, for estimating membrane resistance over a dendrite from observed membrane potentials. We use the Markov random field (MRF) as a prior distribution of the membrane resistance. In the MRF, membrane resistance is not expressed as a function of position on dendrite, but is assumed to be smoothly varying along a dendrite. We apply our method to synthetic data to evaluate its efficacy, and show that even when we do not know the appropriate function, our method can accurately estimate the membrane resistance.

The Myoko volcano, one of the stratovolcanoes in the northern part of the Fossa Magna, Central Japan, has the complicated history (Table 1).The last activity of the Myoko volcano is called the IV stage, and is divided into precaldera, caldera, and central cone substages. The strata formed during this stage are collectively called the Myokosan group which consists of lavas, pyroclastic flow deposits, pyroclastic fall deposits, volcanic mud flow deposits, and lake deposits. They are described in detail and their stratigraphic relations are tabulated in Table 2 and Fig. 4.The rocks of the essential eruptives are basalt, pyroxene andesite and hornblende andesite. They change from basalt to pyroxene andesite and hornblende andesite keeping step with the eruptive order. Quantitatively, the hornblende andesite is predominant.
