An Unusual Case of Carcinoma Erysipelatoides Originating from Gastric Adenocarcinoma

Carcinoma erysipelatoides, also known as inflammatory metastatic carcinoma, is a rare form of cutaneous metastasis. It is most commonly caused by breast carcinoma, but rarely associated with gastric adenocarcinoma. Herein, we report an unusual case of carcinoma erysipelatoides in a 55 year-old female who had been diagnosed with signet ring cell carcinoma of the stomach metastasizing to ovaries

How to Overview the Outcome of Workshop-Type School Training through “Lesson Planning Ability”: A Case of Teacher Training in Physical Education in X City

The purpose of this study is to overview how physical education teachers at junior high schools can acquire “lesson planning ability” through participation in workshoptype (WS-type) school training. According to this case study, the findings can be summarized in three points: (1) physical education teachers improved in their “lesson planning ability” through preparation of a guidance plan in WS-type school training and in exchange with others. (2) WS-type school training functions as a place to learn theory, a place to output, a place to deepen exchange between teachers, a place to share knowledge, and a place to contribute to the training of teachers’ “lesson planning abilities.” (3) Cooperation with schools, educational committees, and universities is indispensable in order to carry out “subjective, cooperative, and active” WS-type in school training

Isospin Physics in Heavy-Ion Collisions at Intermediate Energies

In nuclear collisions induced by stable or radioactive neutron-rich nuclei a transient state of nuclear matter with an appreciable isospin asymmetry as well as thermal and compressional excitation can be created. This offers the possibility to study the properties of nuclear matter in the region between symmetric nuclear matter and pure neutron matter. In this review, we discuss recent theoretical studies of the equation of state of isospin-asymmetric nuclear matter and its relations to the properties of neutron stars and radioactive nuclei. Chemical and mechanical instabilities as well as the liquid-gas phase transition in asymmetric nuclear matter are investigated. The in-medium nucleon-nucleon cross sections at different isospin states are reviewed as they affect significantly the dynamics of heavy ion collisions induced by radioactive beams. We then discuss an isospin-dependent transport model, which includes different mean-field potentials and cross sections for the proton and neutron, and its application to these reactions. Furthermore, we review the comparisons between theoretical predictions and available experimental data. In particular, we discuss the study of nuclear stopping in terms of isospin equilibration, the dependence of nuclear collective flow and balance energy on the isospin-dependent nuclear equation of state and cross sections, the isospin dependence of total nuclear reaction cross sections, and the role of isospin in preequilibrium nucleon emissions and subthreshold pion production.Comment: 101 pages with embedded epsf figures, review article for "International Journal of Modern Physics E: Nuclear Physics".

Fracture of soft cellular solids(Poster session 2, New Frontiers in Colloidal Physics : A Bridge between Micro- and Macroscopic Concepts in Soft Matter)

この論文は国立情報学研究所の電子図書館事業により電子化されました。弾性率が1MPa程度のとてもやわらかいセル固体(多孔質物質)の破壊エネルギーを有限サイズ効果なしに直接測定した。非架橋ポリエチレン(PE)フォームに対する系統的な実験から、ヤング率、破壊エネルギー、応力拡大係数と固体分率(あるいは発泡倍率)の間のスケーリング法則を得た。この法則は従来知られていた弾性率が3000MPa以上の場合と異なっているが、シンプルに説明することができる。また、ポリウレタン(PU)フォームについて行った同様の実験の結果についても触れる。We measured directly the fracture surface energy of soft cellular solids (porous materials) of the Young modulus E around 1MPa, with removing finite size effects. From a systematic tests on non-crosslinked polyethylene (PE) foam (Fig. 1), we obtained dependences of Young modulus, fracture energy, and stress intensity factor on solid fraction. These relations differ from what have been known for hard cellular solids of E larger than 3000MPa but can be interpreted by simple notions. We also mention similar tests performed on crosslinked polyurethane foam (Fig. 2)
