Development of bone-bonding hafnium metal and titanium-hafnium alloys by chemical surface modification

Hafnium (Hf) has attracted considerable attention as a component of biomedical titanium (Ti) alloys with low Young\u27s moduli and/or shape‐memory functionalities, because its cytotoxicity is as low as that of Ti. The drawback of metals is that their bone‐bonding ability is generally low. It is known that apatite formation in the body is a prerequisite for bone‐bonding. Although several chemical treatments have been proposed for preparing Ti for bone‐bonding, there have been no similar investigations for Hf. In the present study, NaOH‐ and heat‐treatments were applied to pure Hf and Ti‐Hf alloys and their bone‐bonding ability was assessed in vitro with the use of simulated body fluid (SBF). After NaOH‐ and heat‐treatments, anatase formed on alloys with low Hf content (20–40% (atom%) Hf); mixtures of sodium titanate and hafnium titanate formed on alloys with similar Ti and Hf content (60% Hf); and hafnium oxide formed on alloys with high Hf content (80% Hf and pure Hf). Precipitates of apatite were observed on all the metals in SBF, except for the alloy with 60% Hf. We speculated that the hafnium titanate formed on this alloy had a low apatite‐forming ability owing to its high negative surface charge, which inhibited P adsorption. The apatite‐forming abilities of the Ti‐Hf alloys strongly depended on their Hf content. The present results indicate that Hf‐based materials have good potential for bone‐bonding

モラエス ノ ニワ : 2 ズイソウ ノ ヘンシツ

This paper is an essay on Moraes’s Tokushima no Bon-odori, part of the outcomes of the Project Studies by the activities in 2011 of Moraes’s Studies Group launched in July 31, 2010. The members of Moraes’s Studies Group, T. Miyazaki (English Literature), M. Satoh (Plant Physiology), M. Sakai (Clinical Psychology), all at the Institute of Socio-Arts and Sciences, The University of Tokushima, have been continuing to try to analyze Moraes’s works and to approach a new facet of Moraes’s biographical aspects. Moraes was fascinated by the far-east Japan, and fell in love with Oyoné, who died soon after the marriage. After her death Moraes decided to live in Tokushima, which was Oyoné’s hometown. He lived with Koharu, Oyoné’s niece, for a while until she died from tuberculosis at the age of 23. His life until his death in Tokushima was a kind of hermit, disregard of his fame as Consul General and Navy high-rank Officer of Portugal, and other financial merits entailed with them. Moraes published Tokushima no Bon-odori in 1913 after Oyoné died. This work might be regarded as based on the forms of diary and essay, seemingly as reports from Tokushima to Bento Carqueja, editor of Porto Commercial Newspaper in Portugal. His interest in Kino Tsurayuki’s Tosa-Nikki (Tosa Diary), which was written in the persona of a woman, seems to be the key to understand the modification in the quality of Tokushima no Bon-odori. Though this work was written as a diary and an essay in the persona of alien people to Tokushima, the tone of this work was quite changed at the final part of his letters to Bento Carqueja, the editor. This tentative paper intends to open a new perspective in a rather fixed image of Moraes and studies about him

モラエス ガ ミタ ホタル

A Portuguese writer, Wenceslau de Moraes (1854-1929), who lived in Tokushima 1913-1929, wrote the essay “Será Ó-Yoné... Será Ko-Haru?...” in June, 1918. In this essay there is a scene in which Moraes heard some children singing an old song of firefly-catching popular among people here in Tokushima in those days. He heard and wrote down the word “tané-mushi” in the song, and he seemed to have thought this word meant a firefly. However, it must have been his misunderstanding of “ta-no-mushi” which is found in an old children’s song handed down in Tokushima district. The word “ta-no-mushi” means an insect of a rice field, indicating a kind of firefly, Luciola lateralis. In the essay, Moraes wrote that just after hearing the children’s song, he saw a firefly in front of his house that was located near Mt. Bizan, and the firefly helped him find the keyhole to open the door of his house by its illumination. Today four species of firefly are found to live in Mt. Bizan: Luciola cruciata, L. lateralis, Lucidina biplagiata and Pyrocoelia disciollis. According to the interviews with some of the elder people in this area, and taking into consideration of the habits of the four firefly species, L. cruciata seems to be the most probable species which Moraes saw in the essay

As the basic activities we organized and have been organizing regular meetings every month or every two months, reading Moraes’s O ‟Bon-odori„ em Tokushima and Ó-Yoné e Ko-Haru. Our activities are still going on and developing with the cooperation with other local groups in Tokushima and Kobe

This paper is an essay on Moraes’s O ‟Bon-odori„ em Tokushima, part of the outcomes of the Project Studies by the activities in 2012 of Moraes’s Studies Group launched in July 31, 2010.

Moraes was fascinated by the far-east Japan, and fell in love with Ó-Yoné, who died soon after the marriage. After her death Moraes decided to live in Tokushima, which was Ó-Yoné’s hometown. He lived with Ko-Haru, Ó-Yoné’s niece, for a while until she died from tuberculosis at the age of 23. His life until his death in Tokushima was a kind of hermit, disregard of his fame as Consul General and Navy high-rank Officer of Portugal, and other financial merits entailed with them. Moraes published O ‟Bon-odori„ em Tokushima in 1916 after Ó-Yoné died. This work might be regarded as based on the forms of diary and essay, seemingly as reports from Tokushima to Bento Carqueja, editor of Comércio do Porto (Porto Commercial Newspaper) in Portugal. He consistently wrote these installment reports from Tokushima in the eyes of a stranger, putting some distance between him and the people in there. Everything seen in the eyes of Moraes wore some beautiful visional aspect because of his memory of Ó-Yoné. He expressed his distress at the attitudes of Tokushima people at some sections in this book; that is, he was seen as a‘ke-tojin,’an alien. This discrepancy and distancing from the people among whom he lived as a hermit, he seemed to see the deep gap between him and the people he loved, leading to the pathetic outcry at the final part of his letters to Bento Carqueja, the editor. This tentative paper intends to open a new perspective in a rather fixed image of Moraes and studies about him

This paper is a part of Moraes’s Studies launched in July 31, 2010. The members of Moraes’s Studies, Takayoshi Miyazaki (English Literature), Masaya Satoh (Plant Physiology), Motohiro Sakai (Clinical Psychology), all at the Institute of Socio-Arts and Sciences, The University of Tokushima, are now continuing to try to analyze Moraes’s works and to approach a new facet of Moraes’s biographical aspects. Moraes was fascinated by the far-east Japan, and fell in love with Oyoné, who died soon after the marriage. After her death Moraes decided to live in Tokushima, which was Oyoné’s hometown. He lived with Koharu, Oyoné’s niece, for a while until she died from tuberculosis. His life until his death in Tokushima was a kind of hermit, disregard of his fame as Consul General and Navy high-rank Officer, and other financial merits entailed with them. Moraes published Tokushima no Bon-odori in 1913 after Oyoné died. This work might be regarded as based on the forms of diary and essay, apparently as reports from Tokushima to Bento Carqueja, editor of Porto Commercial Newspaper in Portugal. He admired the form of diary and essay, especially Japanese type essay like those of Ki no Tsurayuki, Sei Shonagon, Kamo no Chomei and Yoshida Kenko. With this in his mind, Moraes seems to express his inner world via this form of diary and essay. Though this work can be read as written documents of things and events in Tokushima in those days, which aspect is in itself very important and interesting, we should take notice that his innermost world is very meticulously veiled. This tentative paper intends to open a new perspective in a rather fixed image of Moraes and studies about him

モラエス ノ ニワ : 5 モラエス ノ チョサク ノ イチズケ ト ダイ5カイ ナイコク カンギョウ ハクランカイ

This paper and report is based on the oral presentation delivered on 29th, November 2014, as part of Symposium ‘Moraes in Kobe and Tokushima’ held at the Faculty of Integrated Arts and Sciences, Tokushima University, in Tokushima. This is also part of the outcomes of the Project Studies by the activities in 2014 of Moraes’s Studies Group launched on July 31, 2010. The members of Moraes’s Studies Group, T. Miyazaki (English Literature, Comparative Literature), E. Ishikawa (German Literature, Comparative Literature), M. Satoh (Plant Physiology), M. Sakai (Clinical Psychology), all at the Institute of Socio-Arts and Sciences, Tokushima University, have been continuing to try to analyze Moraes’s works and to explore new facets of Moraes’s biographical facts. Moraes was fascinated by the far-east Japan and fell in love with Ó-Yoné, who died young at the age of 39 in Kobe. After her death, Moraes decided to leave Kobe and live in Tokushima, which was Ó-Yoné’s hometown. He lived with Ko-Haru, Ó-Yoné’s niece, for a while until she died from tuberculosis at the age of 21. He led his life until his death in Tokushima for 16 years as a kind of hermit, neglecting his fame as the Consul General and Navy high-rank Officer of Portugal, and other financial merits entailed with the post. Though Moraes is often regarded as a kind of hermit in Tokushima, we should pay more attention to and reevaluate his aspect of a diplomat and consul in Kobe days before coming to Tokushima. He was a very able diplomat and consul, and once actively involved with the 5th National Industrial Exhibition held in 1903. In Tokushima he wrote and published O ‟Bon-odori„ em Tokushima and afterwards Ó-Yoné e Ko-haru. These works might be regarded as based on the forms of diary and essay, seemingly as reports from Tokushima to Bento Carqueja, editor of Comércio do Porto (Porto Commercial Newspaper) in Portugal. Concerning these works as such there seems to be an undercurrent of the image of garden, or paradise, which is strongly connected with the Exhibition he was concerned. In this paper, a tentative reevaluation of his works in Tokushima and the undercurrent of the image of garden related with the 5th National Industrial Exhibition he was involved with in Kobe days
