Is There a Role for Engineering Teachers in the Language Classroom?

This paper focuses on collaborative teaching between foreign language (primarily English) and discipline teachers. The focus is on team teaching, but other examples of collaboration are given. Benefits for students include increased relevance, which positively affects motivation and interest. Teachers also benefit from the interaction with their co-teachers. Team teaching is still relatively uncommon in higher-education EFL contexts, but is recommended in ESP classrooms as an approach to integrating discipline and language studies

Comparison of English Expressions from Science, Technology, and Other Fields by Examining Lexical Bundles

本研究では，6種類のコーパスで共通して使用される「単語連鎖」（lexical bundles）を比較することにより，分野の違いが明らかになるのかという点を調査した。また，どのような単語連鎖により，その違いが現れるのかを検討した．コーパスは，(1) 高校教科書，(2) Scientific American（一般科学雑誌），(3) Nature（専門科学雑誌），(4) 機械系論文，(5)映画スクリプト，(6) 創作散文（imaginative prose）の6 種類を使用し，上位100 位までの4-­gram を対象にコレスポンデンス分析を行った。その結果，広い範囲のディスコースの違いを単語連鎖によって明らかにできることが確認された．また，ある特定専門分野の4-­gramで抽出した特徴表現を効果的なESP教育に用いる手法の可能性が示された．This paper examines whether or not it is possible to identify differences between the use of English expressions in 6 different domains by comparing the lexical bundles extracted from 6 different corpora. The corpora used in this study are (1) the high school textbooks, (2) Scientific American (a popular science magazine), (3) Nature (a science journal), (4) journal papers of mechanical engineering, (5) movie scripts, and (6) imaginative prose. A correspondence analysis was conducted with the highest 100 4-­grams from these corpora. The results show the different discourses in varied domains can be explained by the extracted 4-­grams. This also suggests that the extraction of 4-­grams from a certain domain could lead to anefficient way of teaching domain specific expressions

Isotope production in proton-, deuteron-, and carbon-induced reactions on Nb 93 at 113 MeV/nucleon

Isotope-production cross sections for p-, d-, and C-induced spallation reactions on Nb93 at 113 MeV/nucleon were measured using the inverse-kinematics method employing secondary targets of CH2, CD2, and C. The measured cross sections for Mo90, Nb90, Y86,88 produced by p-induced reactions were found to be consistent with those measured by the conventional activation method. We performed benchmark tests of the reaction models INCL-4.6, JQMD, and JQMD-2.0 implemented in the Particle and Heavy Ion Transport code System (PHITS) and of the nuclear data libraries JENDL-4.0/HE, TENDL-2017, and ENDF/B-VIII.0. The model calculations also showed generally good agreement with the measured isotope-production cross sections for p-, d-, and C-induced reactions. It also turns out that, among the three nuclear data libraries, JENDL-4.0/HE provides the best agreement with the measured data for the p-induced reactions. We compared the present Nb93 data with the Zr93 data, that were measured previously by the same inverse kinematics method (Kawase et al., Prog. Theor. Exp. Phys. 2017, 093D03 (2017)2050-391110.1093/ptep/ptx110), with particular attention to the effect of neutron-shell closure on isotope production in p- and d-induced spallation reactions. The isotopic distributions of the measured production cross sections in the Zr93 data showed noticeable jumps at neutron number N=50 in the isotopic chains of ΔZ=0 and -1, whereas no such jump appeared in isotopic chain of ΔZ=0 in the Nb93 data. From INCL-4.6 + GEM calculations, we found that the jump formed in the evaporation process is smeared out by the intranuclear cascade component in Nb91 produced by the Nb93(p,p2n) and (d,d2n) reactions on Nb93. Moreover, for Nb93, the distribution of the element-production cross sections as a function of the change in proton number ΔZ is shifted to smaller ΔZ than for Zr93, because the excited Nb prefragments generated by the cascade process are more likely to emit protons than the excited Zr prefragments, due to the smaller proton-separation energies of the Nb isotopes

Coulomb breakup reactions of 93,94 Zr in inverse kinematics

Coulomb breakup reactions of 93,94 Zr have been studied in inverse kinematics at incident beam energies of about 200 MeV/nucleon in order to evaluate neutron capture reaction methods. The 93 Zr(n,γ) 94 Zr reaction is particularly important as a candidate nuclear transmutation reaction for the long-lived fission product 93 Zr in nuclear power plants. One- and two-neutron removal cross sections on Pb and C targets were measured to deduce the inclusive Coulomb breakup cross sections, 375 ± 29 (stat.) ± 30 (syst.) and 403 ± 26 (stat.) ± 31 (syst.) mb for 93 Zr and 94 Zr, respectively. The results are compared with estimates using the standard Lorentzian model and microscopic calculations. The results reveal a possible contribution of the pygmy dipole resonance or giant quadrupole resonance in the Coulomb breakup reactions of 94 Zr
