This paper describes a study to develop a method for simulating structure borne noise on reinforced concrete viaducts, consisting of structural vibration and acoustic analyses. Results of acoustic ...analyses and measurements found that there was a high possibility of certain frequency bands where structure-borne noise was the main factor generating noise along the railway. Analytical evaluation of the results revealed that reinforcement of the center slab could reduce structure-borne noise by 1.1 dB at the 12.5 m point and 1.8 dB at the 25 m point.
Conversation is one of the most important channels for human beings. To help communications, speech recognition technologies have been developed. Above all, in a conversation, not only contents of ...utterances but also intonations and tones include important information regarding a speaker's intention. To study the sphere of human speech, microphones are typically used to record voices. However, since microphones have to be set around a space, their existences affect a physical behavior of the sound field. To challenge this problem, we have suggested a recording method using a high-speed camera. By using a high-speed camera for recording sound vibrations, it can record two or more points within the range of the camera at the same time and can record from a distance, without interfering with the sound fields. In this study, we extract voice information using high-speed videos which capture both a face and a cervical part of the subject. This method allows recording skin vibrations which contain voices with individuality and extrapolating sound waves by using an image processing method. The result of the experiment shows that a high-speed camera is capable of recording voice information.
In this paper, we propose a measuring method of the sound field from high-speed movie of dust. The movements of dust in the sound field are affected by the sound vibration. We observe the dust using ...high-speed cameras. The movie is recorded by one high-speed camera in order to get the information of 2-D sound field and two high-speed cameras for 3-D. The influence of air current is reduced from the movement of dust so that the sound field information is extracted. The experimental results indicate that this method is effective to observe the sound field especially composed of low frequency components.
Since the seventeenth century, Japanese ceramics were exported to Europe, yet only few privileged collectors could own them. While the objects proved to intrigue European collectors, the connoisseurs ...had little information about these objects and their country of origin.
Four universal exhibitions were held in Paris in the second half of the nineteenth century. In 1867, during the period of interest in Japanese arts in France, Japan participated there for the first time and its numerous porcelains were exhibited. The Westerners were greatly interested in the Japanese culture, art and in particular its porcelain, as its exotic characteristics were becoming reputable.
During the second exhibition, held in 1878, French amateurs and critics renewed their interest in the Japanese stoneware. In fact, the simplicity and sobriety of Japanese stoneware were preferred to porcelain, as it was considered a reflection of Japanese ceramic culture. This aestheticism, more exotic and refined, strongly influenced the specialists of Japanese art in France.
In 1889, Japanese porcelain was severely criticized for its lack of originality and for its imitation of European models in shape and décor. However, French ceramicists drew inspiration from Japanese stoneware quickly, as it was considered a pure representation of the Japanese ceramic art much more than porcelain.
This report aims at investigating what Japanese ceramics represented for the French in the second half of 19th century. We are particularly interested in identifying how the French viewed and interpreted Japanese culture, art, motifs, colours and emblems by understanding how these objects were used in France. The use of these objects will be primarily examined at the time of universal exhibitions in Paris when Japonism peaked.
Japonų keramikos dirbiniai nuo septyniolikto amžiaus buvo gabenami į Europą, tačiau tik keletas privilegijuotų kolekcionierių galėjo juos įsigyti. Nors Europos kolekcionieriai šiais dirbiniais labai domėjosi, žinovai turėjo labai mažai informacijos apie pačius daiktus ir jų kilmės šalį.
Antroje devyniolikto amžiaus pusėje Paryžiuje surengtos keturios pasaulinės parodos. 1867-aisiais, kai prancūzai itin domėjosi Japonijos menais, Japonija pirmą kartą dalyvavo parodoje ir eksponavo daugybę porcelianinių dirbinių. Vakariečius nepaprastai sudomino Japonijos kultūra, menas ir ypač porcelianas, kurio egzotinės savybės buvo vis labiau vertinamos.
Šio darbo tikslas – ištirti, ką japonų keramikai pristatė prancūzams antrojoje XIXa. pusėje. Labiausiai rūpi sužinoti, kaip prancūzai vertino ir suvokė japonų kultūrą, meną, pagrindinius motyvus, spalvas ir emblemas, stengiamasi suprasti, kaip šie daiktai panaudoti Prancūzijoje. Jų naudojimas pirmiausia bus ištirtas pasaulinių parodų Paryžiuje laikotarpiu, kai suklestėjo japonizmas.
Dihydropyrimidine dehydrogenase (DPD) deficiency induces severe adverse events in patients receiving fluoropyrimidines. We encountered a 64-year-old DPD-deficient man with a severe ...capecitabine-related gastrointestinal disorder. He received capecitabine-containing chemotherapy after rectal cancer resection. During the first course of chemotherapy, he developed severe diarrhea, a fever, and hematochezia. Endoscopy revealed mucosal shedding with bleeding throughout the gastrointestinal tract. DPD deficiency was suspected because he developed many severe adverse events of capecitabine early and was finally confirmed based on the finding of a low DPD activity level in peripheral blood mononuclear cells. After one month of intensive care, hemostasis and mucosal healing were noted, although his gastrointestinal function did not improve, and he had persistent nutritional management issues.
We previously reported preliminary safety results for a new method, endoscopic detachable snare ligation (EDSL), for diverticular hemorrhage. This method does not need endoscope removal to attach a ...ligation device after detection of the bleeding site. The aim of the present study was to evaluate the efficacy and safety of EDSL in a larger patient population.
This prospective study was conducted in 12 institutions. Patients suspected of having diverticular hemorrhage without serious systemic disease were enrolled. The primary endpoint was early (within 30 days) recurrent bleeding rate in patients treated with EDSL. The secondary endpoints were overall early recurrent bleeding rate in patients with definite diverticular bleeding and adverse events in patients treated with EDSL.
From June 2015 to March 2017, bleeding diverticula were detected in 123 of 205 enrolled patients (60%), of whom 101 (82%) were treated with EDSL. Most patients (20/22) in whom EDSL was not successful were treated with clipping. The early recurrent bleeding rate was 7.9% (95% confidence interval, 2.6%-13.2%; 8/101) in patients who could be treated with EDSL. The median total endoscopic and EDSL procedure time was 40 minutes (interquartile range, 15-71) and 4 minutes (interquartile range, 1-7), respectively. Two mild adverse events, colonic diverticulitis and temporary abdominal pain, were observed.
EDSL was confirmed to be useful and safe for treatment of colonic diverticular hemorrhage. (Clinical trial registration number: UMIN 000001858.)
