ed for the propane and propane-hydrogen jet diffusion flames. A centrifuge was used for quantitative measurement of gravity effect, and frequency analysis was performed for the flickering flames. From the result of measurements under various gravity levels, it was clarified that the flickering frequency increased with an increase in the gravity level and it was correlated with two relationships expressed by the Strouhal number and the Froude number. One relationship was St∝Fr^<-0.41> for high Froude numbers (Fr≥100), and the other was St∝Fr^<-0.50> for low Froude numbers (Fr≤100). It meant that the Froude number gave the criterion of the flickering behavior and that flickering frequencies expressed by these two equations were affected by buoyancy in different ways. From the frequency analysis, it was found that oscillations of a flickering flame and a thermal convection around the flame were linked, but the characteristic of each flickering motion was different in the stability of periodicity.

概要:
application/pdf<br />Journal Article<br />This study investigates how to control the stream of bioconvection. Bioconvection is a phenomenon that is autonomously generated by the high density culture media of microorganisms. In this study,
…
"negative galvano-taxis" of microorganisms are used to control the downward stream of bioconvection. For that purpose, an array of 15 negative electrodes is installed at the top of the observation pool. The basic effects of electrical field on bioconvection was investigated. The result shows that the status of bioconvection classifies three different regions by the strength of electrical field. The lower area is "natural convection region" in which bioconvection is not changed by electrical field. Middle area is "convection control region" in which down flow stream near the negative electrode is brought to just under the negative electrode. The higher area is "forced convection region" in which the down flow stream that is generated under negative electrode dominates whole of convection stream and original bioconvection stream is disappeared. This controlled downward flow has a possibility as a driving source for micro fluid machines.

with a small quantity of exciplex-forming dopants, TMPD (N, N, N', N'-tetramethyl-1,4-phenylene diamine) and naphthalene. A Nd : YAG laser (355nm) was used for excitation of the fuel. The fuel spray was injected from a swirl atomizer into an air stream. Air temperature was changed from room temperature to 1000k which was higher than the self-ignition temperature of a kerosene spray. Distributions of the fuel droplets and vapor were strongly affected by the air temperature. Furthermore it was confirmed that the fuel vapor was transported into recirculating flow area formed on the flame holder.

概要:
application/pdf<br />Journal Article<br />Quantitative investigation of the gravity effect was performed for acetone and kerosene pool fires. A centrifuge was used to examine the gravity effect. Small-scale pool fires were observed
…
under various high gravity fields. Regions of stable flame, puffing flame and irregular oscillatory flame were mapped with the gravity level and pool diameter. Flame height decreased and oscillatory frequency increased with an increase in the gravity level. Behavior of the flame height was agreed quantitatively with the scaling prediction presented by Orloff and Heskestad. Puffing phenomena observed under various gravity fields were summarized with the Strouhal number and Froude number. As the result, we could obtain an empirical equation of St=0.517Fr^<-0.502>. From this equation, puffing frequency could be estimated for a flame of various pool diameter varying from 0.01 to 50 meters.

概要:
application/pdf<br />Journal Article<br />Diesel spray impinged normally on a flat wall was investigated. Spray tip penetration and spray volumes of before and after impingement were measured on high speed photographs of the sprays
…
which were injected by a single shot injection system into a high pressure chamber of cold state. The effects of the spray tip penetration, spray volume, entrainment mass and air-fuel ratio were discussed on the sprays of before and after impingement. The volume of the post-impingement spray was calculated using axi-symmetrical model. It was greatly affected by the distance between the injection nozzle and the wall. When the impingement distance was shorter than the break-up length of the original spray, the entrainment mass as well as the volume of post-impingement spray was the larger than that of the original spray at the same inspection time. To calculate the average spray concentration of after impingement spray, the fuel film stuck on the wall was measured. The average air-fuel ratio of the impingement spray increased faster than the free spray because the spray concentration in a space decreased by the fuel stuck on the wall.

between first and second injections were widely varied. Heat release rate was analyzed to evaluate the combustion phenomena in the engine. As the result, ignition delay period for two-stage injection became longer than that for single-stage injection when the amount of fuel in the first stage injection was small. However, when the amount of fuel in the first injection was large, there was no difference of ignition delay period between two-stage injection and single-stage injection. NO and Smoke emissions and fuel consumption were improved by two-stage injection when ingition delay period became long.

概要:
application/pdf<br />Journal Article<br />This paper presents numerical results on chaotic vibrations of a shallow cylindrical shell-panel under harmonic lateral excitation. The shell with a rectangular boundary is simply supported
…
for deflection and the shell is constrained elastically in both in-plane directions. The effects of bi-axial in-plane elastic constraint on the chaotic behaviors of the shell are focused on. Using the Donnell-Mushtari-Vlasov type equation modified with an inertia force, the basic equation is reduced to nonlinear differential equation of a multiple-degree-of-freedom system by the Galerkin procedure. To estimate regions of the chaos, first, nonlinear responses of steady state vibration are calculated by the harmonic balance method. Next, time progresses of the chaotic response are obtained numerically by the Runge-Kutta-Gill method. The chaotic responses due to dynamic snap-through are examined by Fourier spectrum, Poincare projection and Lyapunov exponent. Contribution of multiple modes of vibration to the chaos is examined carefully by the Lyapunov dimension. The main results can be summarized as follows. Loosening the in-plane constraint perpendicularly along the curved edges and tightening the in-plane constraint along the straight edges, chaotic motion is restricted with less number of modes of vibration.

概要:
application/pdf<br />Journal Article<br />The equilibrium composition and spectral absorption coefficient of SiC ablation layer plasmas have been calculated for temperature of 5000 to 7000 K, layer thickness of 0 to 7.5mm, and
…
pressure of 0.1 to 1.0MPa. The radiations included were molecular bands, atomic lines, and continuum processes. The absorption coefficient thus calculated was applied to a simplified shock layer model for the Jupiter entry probe to investigate the effectiveness of the ablation layer in reducing the radiative heating from a shock layer to a body surface. It was found that the SiC ablation layer is very effective to protect the body from radiative heating and that the photoionization processes of atomic carbon and silicon were mainly responsible for radiative absorption at high photon energy range. Furthermore the molecular carbon bands were effectively absorptive in relatively low photon energy range, particularly at low temperatures.

概要:
application/pdf<br />Journal Article<br />The authors developed a new testing equipment for studying statically indeterminate fracture mechanics. Its development purpose is to clarify load history-dependency of the collapse load.
…
The equipment has two actuators orthogonalized. The horizontal actuator applies the axial force and the perpendicular one does the bending moment. In the experiment for examining the effect of load hysteresis on the collapse load, both actuators can keep the preceding load to the constant load value, until axial force and bending load reach the theory collapse point. The actuators can apply the following load under the displacement control in the experiment. The performance of the equipment was confirmed by demonstration tests using single-edge notched specimens of SUS 304 steel. The experimental result clarified load historydependency on collapse load in SUS 304 single-edge notched member subjected to combined tension and bending.

概要:
application/pdf<br />Journal Article<br />To clarify the effect of water content on combustion characteristics of watery
…
materials, combustion test of a high water-permeable balsa wood was performed using a thermogravimetric furnace. The furnace temperature is between 650℃ and 1000℃, and water contents in the small balsa pieces (0.3g) were varied up 70 wt%. Mass reduction during pre-heating, volatile matter combustion and char combustion were measured with a microbalance. Also, the variations of flame temperature and center temperature of the test piece during combustion process were measured. On the combustion of high water-contained balsa, it was found that ignition started before the water was evaporated completely. It means that two proceses, devolatilization of volatiles and vaporization of remaining water, are proceeding simultaneously during the volatile matter combustion. Ignition delay and retention time of volatile matter combustion increased with increasing the water content. The increases of flame temperature and center temperature of the test piece were prevented by the latent heat of water vaporization. The combustion rate of volatile matter was drastically reduced in proportion to the water content. Also, it was confirmed that a part of char burned during the latter stage of volatile matter combustion. The effect of water content on char combustion rate was small. From this study, it was concluded that the water content over 50 wt% affected remarkably to the volatile matter combustion.

keeping the upper frictional forces of the fingertips, which is applied on the grasped object after the object contacts with the floor. Slow change rate of moving the object mass to the floor has the effect of reducing the peaks value and temporary convergent value of the impact force. Moreover, smaller grasping force at a moment of collision can restrain the violent impact. Next, taking the strain pattern of the fingertips into consideration, the simulation of human placing motion is performed. When the viscosity of the fingertips in the shearing direction is higher, the impact force of the simulation has high convergent value similar to the case where the grasping force is set to be larger.

…
and potential travelers about the picturesque natural scenery one can find around the Lake Dis 'ct. Yet, the Guide is not simply a so-called guidebook. Upon its analysis from the perspective of newly emerged literary genre, Nature Writing, the Guide manifests itself as a more complex literary work composed by a Romantic concerned about the deterioration of the region's environment, and struggling for years to establish his own identity. Thus, the Guide could be read other than as one of guidebooks at least in two ways : as a serious document calling for the preservation of the Lake District and, more importantly, as one of the autobiographical attempts.

概要:
application/pdf<br />Departmental Bulletin Paper<br />From the start of his writing career, Thomas De Quincey was so dens ly surrounded by literary culture that it was difficult for him to write as he pleased. He had been forced to meet
…
various editorial requirements and be sensitive to readers' response. This biographical fact should be considered when interpreting the Confessions of an English Opium-Eater and its long history, along with some critical appreciation of the generic characteristics of the Confessions as a work of modern autobiography. In 1821 the Confessions was published in London Magazine, and in a few months it circulated again in a book form. Then, in 1856 the work reappeared in one of the volumes of De Quincey's authorized collected writings. This history of the Confessions is also that of the author's revisionary endeavour, through which the revised version emerged quite differently from the original. And that is where the dynamics of these two vectors one originating from literary culture, and the other from the author's concern over his future identity as a writer holds a special significance for the Confessions itself. After working as the editor of a local periodical, The Westmorland Gazette. De Quincey composed the Confessions, and the work could be regarded as a typical article f r his contemporary magazines especially in view of its anonymous publication, and ample quotations from both classical and contemporary literature as well as philosophical knowledge scattered 'throughout it. However, viewed with wider perspective not only upon the literary culture but the work's autobiographical theme, the Confessions has noteworthy characteristics which might bring the author from his strictly conditioned status as a magazine contributor into the more genuine field for writers with abilities to produce original literary works. And it was his extraordinary opium experiences which could make the transition possible. The Confessions of 1821 does hot tell whether it will happen or not, and the question remains to be answered till the time when the history of the work unfolds.

government, universities and large firms, because new venture is expected to increase opportunities of employment and to lead Japanese industries in the future. Now the promotion of small business start-ups also become a pillar of economic reformation by the government. One of the main part of these policies is the improvement of structure of venture finance. The purpose of this paper is to consider whether securitization scheme can make a contribution to the development of venture finance. Securitization scheme may be divided into four types, that is, (1) securitization of assets by venture firms, (2)securitization of loan obligation to firms by banks, (3) securitizationof bond obligation to firms by investors, (4)securitization of equities of venture firms by investors. Of these four es (4)is the most applicable to venture finance.

…
iving micro manipulator/actuator or not. Motion control of protozoa was made by using the negative galvanotaxis. In the previous study, it was succeeded to control the paramecium along figure '8'. Its controllability, however, has problems about speed control, rapid turn and position accuracy. Therefore, this paper first investigates the application of pulse width modulation method for the control of paramecium's swimming speed. However, the results show that the application of the pulse electric field causes the strange reaction such as rotation, zigzag swimming, etc. Next, rapid stopping phenomenon of paramecium's swimming by the sudden stop of electrical field is investigated to improve the rapid turning ability of paramecium's swimming. To adopt this method to the automatic motion control program, paramecium can be controlled along any shaped guide route. Paramecium's generating force is also measured by pushing the small object by controlled paramecium. It is estimated about 2.7×10^<-8> N. For an example of the micro mechanical application, the micro impeller (φ 0.5 mm) is rotated by paramecium. These results show that micro mechano-bio-fusion system can be constructed by using protozoa.

…
eter (LDA). Glass spheres of 389μm in mean diameter were loaded into the injection water by a particle mixer and after then injected into still water bath. The particle/water jet injectors were made by brass pipes of which diameters were 5 and 8 mm. The mean velocities of the center of the jet were set as 1.8 and 1.5 m/s for 5 and 8 mm pipes, respectively. The initial volume fraction was set as 0.087% in all experiments. The results of vertical relative velocity between particle and water indicate that the particles have same velocity as water at the outlet of the jet however particle velocities are larger than that of water at the expanded jet in downstream. From the results of the transverse relative velocity, it is considered that the particle can get larger velocity than water at a certain downstream from the outlet. These features are well explained by using local Stokes number defined by local time scale of the turbulence and particle time constant as well as Saffman's lift force.

spray were studied experimentally. Palladium catalyst supported on the cordierite honeycomb monolith was used. Inlet temperature was elevated up to 700 K to evaporate the kerosene spray. Premixed gas of air and kerosene vapor was introduced into the catalyst. The catalytic combustion and gas phase reaction after catalyst were observed in this combustion system. The lean limit of the catalytic combustion was not affected by the space velocity and equivalence ratio of the mixture, but it was greatly affected by the inlet temperature. The parabolic shape blue flame that was supported on the catalyst was formed when the supplied mixture was not completely burned in the monolith. To clarify a reaction process in an combustive gas between the monolith and the blue flame, CO, HC(C_1～C_7) and NO were analyzed. When the blue flame was observed after the catalyst, the HC and CO were formed from the unburned composition of fuel and they were burned as the blue flame. The NO emission level of the catalytic combustion was very low compared with the gas phase reaction of lean mixture.

The acoustic medium is assumed to be air, and the effect of the back reaction of the sound field is neglected in the beam response equation. Non-dimensional acoustic power, sound radiation efficiency, and acoustic power conversion efficiencies are presented as functions of wavenumber ratio and beam loss factors. It is shown that the power conversion efficiency of the infinite beam is inversely proportional to the wavenumber ratio and independent of the loss factor below coincidence, and is approximately proportional in inverse to the loss factor above coincidence. The power conversion efficiency of the finite beam has dull peaks with values roughly inverse-proportional to the loss factor at nonresonant frequencies. The similarity of acoustic power radiation between infinite beams and finite beams has been observed when the length and loss factor of beams is increased.

ylcholines in glycerol. In this study, we investigated five different saturated diacyl phosphatidylcholines with carbon number from 14 to 18 in their acyl chains. It was found that lamellar spacings increase linearly as increasing the carbon number in the chains and that the increment is 0.10 ± 0.01 nm per one carbon atom. The lamellar diffraction intensity data were analyzed, by applying a method proposed by Adachi [Chem. Phys. Lipids 107 (2000) 93-97]. The results indicate that the moiety around polar headgroup regions is almost unchanged, being independent of the carbon number.

rder to study its temperature dependence, the hydration force of dipalmitorylphosphatidylcholine bilayers was investigated at temperatures below freezing. Using known chemical potential of ice, the strength of the interbilayer repulsive force of dipalmitoylphosphatidylcholine bilayers at subzero temperatures was estimated and X-ray diffraction was used to estimate the interbilayer spacing. An exponentially decaying repulsive force with a decay constant of 0.15 nm was observed. The present subzero temperature data are slightly grater than those measured at temperatures about 20℃.

…
(TEM) and X-ray analysis. Molecular motion in crystalline and amorphous phases was evaluated by nuclear magnetic resonance (NMR) techniques. The series of solution-crystallized mats was prepared from different polymer concentrations. TEM results indicate these samples consist of lamellae aligned parallel to the mat surface. The observed high order scattering of small-angle X-ray scattering (SAXS) patterns indicate a regular stacking of lamellae. The long period was similar to 11 nm, independent of prior polymer concentration. Wide-angle X-ray diffraction analysis also revealed the same level of crystallinity for these solution-crystallized samples, well coincident with H-1-NMR results. These indicate that the thickness of crystal/amorphous layers was constant, which was also confirmed by layer thickness distribution analysis for this series of samples, based on direct TEM observation. However, the SAXS peak gradually grew and sharpened with increasing prior polymer concentration. H-1-NMR results also indicate amorphous chain mobility was restricted for the sample prepared from lower polymer concentration in spite of unchanged crystallinity and relaxation characteristics for crystalline chains. Morphological and relaxation characteristics information demonstrates that lower prior polymer concentration might prefer formation of tie molecules which connect tightly crystalline layers. In contrast, the higher concentration could trap loosely entangled chains in amorphous layers, providing for an ease of chain relaxation estimated by H-1-NMR analysis.

attempts to provide an answer to the problem within the Optimality Theory framework. Some constraints and their rankings are proposed in regard to the occurrence and non-occurrence of the moraic obstruents in loanwords. The constraints refer to the prosodic structures of both English and Japanese languages. This seems to suggest that Japanese people try to imitate English pronunciation, especially English stress as closely as possible.

think that it is not necessary to have knowledge of special mathematics in order to teach easy mathematics. In this paper the author claims that it is really important to have enough knowledge of special mathematics and rich experience of doing actual education in order to teach mathematics well.We have developed a system controlling over an electron-electron coincidence spectrometer consisting of two hemispherical analyzers, an x-ray source, and an electron gun. It has been confirmed, by measuring x-ray- and electron-excited Auger-electron spectra and x-ray photoelectron spectra, that this control system works reliably. Using the system, a distribution curve, leading to an Auger-photoelectron coincidence spectrum, has been measured for the time intervals between an Auger-electron and a photoelectron in Auger-photoelectron pairs, at the L3WAuger and 2p3/2 photoelectron peaks in nickel.

ds in a simplified version of the Gunnarsson-Schonhammer calculation based on the single-impurity model of Anderson. By assuming that the band of valence states has an infinitely narrow width, this approach involves only a simple calculation. A 4f3 configuration as well as 4f0, 4f1, and 4f2 configurations is taken account of as a basis set in this calculation. This model reproduces qualitatively the main features of XPS 3d spectra in La compounds, when a value of about 10eV is chosen for the single-particle energy ε of 4f state. It also predicts a new final state which has enough weight to be observed and is composed of the sizable 4f1, 4f2, and 4f3 configurations, when the value of ε is of the order of -1eV, corresponding to Ce systems. This implies that this final state might play an important role to form a shoulder that is observed at the high-energy side of the most intense peak in some of the Ce compounds but has been neglected so far. In addition, it is inferred from this calculation that the strong 4f1- 4f3 mixing forms the most intense peak

概要:
application/pdf<br />Departmental Bulletin Paper<br />La "Pala Strozzi" di Andrea Orcagna del 1357 fu considerate da Millard Meiss nel suo "Painting in Florence and Siena after the Black Death" come l' opera piu' rappresentativa
…
riflettente il clima dopo la peste del 1348, cioe' il clima irrazionale, poco naturale e tendente al misticismo. E per esempio, il modo di porre al centre della composizione la figura frontale e grandiosa di Cristo in dominio, secondo il Meiss, non esisteva nei polittici della prima meta' del Trecento, bensi' esisteva nelle tavole d' altare del - Duecento. Ed il fatto mostro, sempre secondo lui, la simpatia d' Orcagna per lo stile arcaico quale antitesi all' arte naturale e razionale di Giotto e dei giotteschi. Ma penso che il polittico Stefaneschi, la "Prova del fuoco davanti al Sultano" della Cappella Bardi sempre di Giotto, il "Trionfo di San Francesco" del Maestro delle Vele ad Assisi, oppure il "Trionfo di San Tommaso d' Aquino" di Lippo Memmi della Santa Caterina di Pisa, tutte le opere nate sotto l' influsso artistico della Tomba di Arrigo VII, abbiano contribuito alia composizione simmetrica della tavola d' Orcagna costituita da varie figure e dominate al centre dalla figura grandiosa e assisa di Cristo. Secondo il Paoletti, la fugura centrale assisa rappresento' sia Cristo che Dio Padre, perche'con la colomba raffigurata in su dovette costituire il concetto della Trinita'. Inoltre la figura inginocchiata di sinistra significo' sia San Tommaso d' Aquino che Tommaso Strozzi, mentre quella di destra significo' sia San Pietro che Piero Strozzi. II fatto verificato qui di mostrare due doppi-personaggi per un altare di Trinita' potra' essere considerate come riflesso dell' Altare di San Bartolomeo incluso sotto la Tomba di Arrigo VII, coratterizzato dal concetto della Trinita' e dalla presenza appunto di doppi-pirsonaggi, cioe' Dio Padre-Uguccione della Faggiuola e Cristo-Fnancesco della Faggiuola. Gli affreschi di Nardo di Cione di circa 1355, "Paradiso" , "Giudizio Universale" e "Inferno" eseguiti per la stessa cappela in Santa Maria Novella riflettono varie simili composizioni gia' viste negli affreschi di Buffalmacco nel Camposanto di Pisa, ma specialmente il "Paradiso" e' dominata dalla composizione gia' apparsa nel pannello esistente nella sacrestia di Santa Maria Novella, opera di Maestro delle Immagini Domenicane caratterizzata dalla bidimensionalita', dalla giustapposizione verticale delle figure in ritratto e poi dalla composizione simmetrica, tutti caratteri derivati dall' arte di Tomba di Arrigo VII. Tale ricca pisanita' e la comunanza con l' arte della Tomba di Arrigo accertate nelle arti della Cappella Strozzi dovettero essere causate dagli interventi sia di Don Piero Strozzi che di Jacopo Passavanti, tutti e due gia' lettori dello studio teologico di Pisa e poi priori del convento di Santa Maria Novella. Sia la "Pentecoste" della vela sinistra che il "Trionfo di Tommaso d' Aquino" della parete sinistra degli affreschi della Sala Capitolare (Cappella degli Spagnoli) nel convento di Santa Maria Novella, eseguiti da Andrea da Firenze nel 1366-68, sono dominati dalle composizioni simmetriche e sottolineano l' esistenza della figura nucleare posta sull' asse centrale dell' insieme, cioe' sottolineano varii coretteri gia'visti nella tomba imperiale pisana. Per capire il perche' di tale fatto, bisognera' riccordare che gia' in quella sala esisteva il polittico di Bernardo Daddi raffigurante la Madonna col Bambino e quattro santi con i testi di Tommasp d' Aquino riguardanti il concetto di Corpus Domini. Per tale opera propagandistica dela dottorina dorftenicana, Daddi sottolineo' lo schema rigidamente simmetrico delle figure e la frontalita' della figura principale assisa. Era pieno di senso gerarchico appunto gia' visto nella Tomba di Arrigo VII. Andrea da Firenze inoltre mostro l' interesse sulla Tomba di Arrigo VII nel tondo della vetrata della facciata di Santa Maria Novella. Raffiguro' "l' Incoronazione della Vergine" e vi introdusse la figura inginocchiata del committente risalendo allo schema scultoreo in cima della tomba imperiale pisana, e facendo accerchiare tutto l' insieme con il motive oraamentale di foglie d' acanto simile a quello delle colonne tortili poggianti la tomba pisana. E di piu' Andrea creo' il tipo del trittico portatile raffigurante Maria al centro, sorretto dalla base al cui centre e' raffigurato il Cristo morto nella sua tomba, e sulla parte superiore delle due ali laterali rappresento'la scena dell' Annunciazione. Tutto l' insieme si puo'considerare come riflesso dello schema della Tomba di Arrigo VII composto dalla vera e prapria tomba nel pianterreno, dal gruppo scultoreo dell' "Imperatore assiso sul trono e cortigiani" nel primo piano, e sopra di cio, dalle statue raffiguranti i' Annunciazione. Anche Giovannni da Milano, di origine lombarda, mostro'l interesse sulla Tomba di Arrigo VII. Compose il suo Polittico di Ognisanti con sette pannelli principali riflettendo la composizione statuaria del primo piano della tomba e con le predelle raffiguranti le varie figure in piedi, riflettendo sia le figure degli apostoli sul sarcofago dell' Imperatore che le tre statue a tutto tondo poste sull' altare di San Bartolomeo. Giovanni dovette creare un altro polittico sempre riflettente lo schema architettonicoscultoreo della Tomba di Arrigo VII. II suo pannello centrale sara' "Cristo in Maesta' "della collezione Contini Bonacossi di Firenze. Isolate nel centre del pannello con i' attegiamento frontale e col senso fortemente gerarchico, Cristo riflette la figura dell' Imperatore assiso sul trono posto al centre del primo piano della tomba imperiale pisana. II Maestro della Cappella Rinuccini e' continuatore degle affreschi di Giovanni da Milano lasciati non finiti nella Cappella Rinuccini in Santa Croce, ed li ha compiuti. Questo pittore, forse per l' influsso orcagnesco ma anche per quello dato da Giovanni da Milano, mostroT interesse sulla Tomba di Arrigo VII. Nel polittico dell' Accademia di Fienze raffigurante "la visione di San Bernardo" ,mise nei due tondi delle estremita' di destra e di sinistra, la scena dell' Annunciazione riflettendo il gruppo statuario sopra il tetto del primo piano della tomba imperiale pisana, ed insieme con la raffigurazione del martirio del San Quintino posta nella predella, costituiscono il riflesso di varii piani della Tomba di Arrigo VII. La sua tavola "San Bartolomeo, San Michele e San Giuliano" dell' Accademia di Firenze, senza le suddivisioni per separare una figura dall'altra, si puo'considerare come opera piu' progredita rispetto al trittico raffigurante tre santi stanti gia' a Firenze iniziata nella prima meta' del Trecento dal Maestro del polittico della cappella Medici, e nel secondo Trecento proseguito da Nardo di Clone. E' certamente l'opera sintomatica per farci sapere sull' esistenza in questo maestro dell' interesse concreto sulla Tomba di Arrigo VII, e specialmente in questo caso sull' Altare di San Bartolomeo composto da tre statue stanti a tutto tondo.

application/pdf<br />Departmental Bulletin Paper<br />In order to look for more skillful usage of antimicrobial finished goods (AFG), we got the information through a questionnaire. The results of questionnaire obtained from 500 persons
…
(female: 92%) are as follows. 1) About 90% of the people have AFG. The main reasons to select these goods were that many people are willing to keep everything clean and to prevent food poisoning. However, half of the people answered that they unexpectedly bought the AFG, suggesting the tendency of over antimicrobial treatment of many goods. 2) The people who are 20 to 40 years old with children have the tendency to prefer to buy AFG. 3) Half of the people are anxious about the side effects of the treated substrates showing antimicrobial effects. People, who are the more anxious about the side effects of antimicrobial substrates, the more have the tendency to avoid buying AFG. 4) Most people consider that the antimicrobial effects of the goods do not last for a long time. 5) Overall, it became clear that the information about the detail, durability and safety of AFG is limited, and it is necessary to educate consumers not to buy AFG easily.
