    Spectroscopic studies of the mechanism for hydrogen-induced exfoliation of InP

    The motion and bonding configurations of hydrogen in InP are studied after proton implantation and subsequent annealing, using Fourier transform infrared (FTIR) spectroscopy. It is demonstrated that, as implanted, hydrogen is distributed predominantly in isolated pointlike configurations with a smaller concentration of extended defects with uncompensated dangling bonds. During annealing, the bonded hydrogen is released from point defects and is recaptured at the peak of the distribution by free internal surfaces in di-hydride configurations. At higher temperatures, immediately preceding exfoliation, rearrangement processes lead to the formation of hydrogen clusters and molecules. Reported results demonstrate that the exfoliation dynamics of hydrogen in InP and Si are markedly different, due to the higher mobility of hydrogen in InP and different implant-defect characteristics, leading to fundamental differences in the chemical mechanism for exfoliation

    A Comparison of Milton\u27s Treatment of Death in Death of a Fair Infant and Marchioness of Winchester

    Get PDF
    It is a tribute to Milton\u27s genius to study his delicate line of demarcation between the treatment of death in Marchioness of Winchester and Death of a Fair Infant. In the latter poem, Mi.lton imbues his work with a tone of comfort and hope-a tone which we do not find in the former poem. Of course, we must keep in mind the fact that in Death of a Fair Infant, Milton was emotionally connected with the deceased, and would naturally inject his lines with a note of personal grief and sympathy for the bereaved. Upon contemplating Milton\u27s lines, the reader is aware that his treatment of death is in perfect harmony with the subject. There are beautiful allusions to light, somewhat ethereal figures, and nowhere do we find ponderous passages of dark, black mourning which would add a grimness totally out of keeping with the qualities of fancy in this poem. He tells the lamenting mother that her loss is a gift of God, and closes his poem on a rather enigmatic note of promise

    Review of C. Derrington & S. Kendall's 2004 publication, Gypsy Traveller Students in Secondary Schools: Culture, Identity and Achievement. Stoke on Trent, UK and Sterling USA: Trentham Books. (ISBN 1 85056 320 8). The book is concerned with English Gypsy Travellers (although six participants were Irish Travellers), as opposed to fairground or circus people and new age travellers

    UPAYA MENINGKATKAN PRESTASI BELAJAR TEORI PERBAIKAN ENGINE BERIKUT KOMPONENNYA MELALUI PEMBELAJARAN KOOPERATIF TIPE PETA KONSEP PADA SISWA KELAS XI B PROGRAM KEAHLIAN TEKNIK SEPEDA MOTOR DI SMK DIPONEGORO DEPOK

    Penelitian ini bertujuan untuk mengetahui peningkatan prestasi belajar teori perbaikan engine berikut komponennya melalui model pembelajaran kooperatif (cooperative learning) tipe peta konsep (concept mapping) pada siswa kelas XI B program keahlian teknik sepeda motor di SMK Diponegoro. Penelitian dilakukan di SMK Diponegoro Depok, Sleman, dengan subjek penelitian adalah siswa kelas XI B yang berjumlah 17 siswa. Penelitian ini merupakan jenis Penelitian Tindakan Kelas (PTK), melalui pendekatan model pembelajaran kooperatif tipe peta konsep. Model/desain penelitian yang diterapkan mengacu pada model Kurt Lewin yang dilakukan dalam 4 tahapan yaitu perencanaan, tindakan, pengamatan dan refleksi. Penelitian tindakan kelas dilakukan dalam 3 siklus. Pelaksanaan siklus dimulai dari tahap perencanaan penelitian berdasarkan studi pendahuluan. Tahap pelaksanaan tindakan kelas dengan penerapan pembelajaran kooperatif tipe peta konsep, meliputi; penyajian materi, pembentukan kelompok, diskusi kelompok, presentasi kelas dan evaluasi untuk mengetahui prestasi hasil belajar siswa. Tahap pengamatan yaitu dengan mengisi lembar observasi keterlaksanaan proses pembelajaran kooperatif tipe peta konsep oleh observer. Tahap refleksi yaitu mengevaluasi pencapaian dan kekurangan dari tiap-tiap siklus untuk perbaikan pada siklus berikutnya. Hasil penelitian menunjukkan bahwa prestasi belajar siswa meningkat pada setiap siklus setelah diterapkan pendekatan pembelajaran model kooperatif tipe peta konsep. Hal ini ditunjukkan dengan besarnya rata-rata persentase nilai teori perbaikan engine berikut komponennya dan ketercapaian ketuntasan belajar siswa yang mengacu pada KKM. Pada siklus 1 rata – rata prestasi belajar siswa mencapai 75,87 dengan presentase jumlah siswa yang mencapai ketuntasan belajar yaitu 64,70% atau sebanyak 11 siswa. Pada siklus 2 rata – rata prestasi belajar siswa meningkat menjadi 77,42 dengan persentase jumlah siswa yang mencapai ketuntasan belajar meningkat 11,70% menjadi 76,40%, meningkat 2 siswa menjadi 13 siswa. Pada siklus 3 rata – rata prestasi belajar menjadi 75,35 dengan persentase jumlah siswa yang mencapai ketuntasan belajar meningkat 5,90% menjadi 82,30%, meningkat 1 siswa menjadi 14 siswa

    Effects of Aspen Phenolic Glycosides on Gypsy Moth (Lepidoptera: Lymantriidae) Susceptibility to \u3ci\u3eBacillus Thuringiensis\u3c/i\u3e

    Performance of the gypsy moth, Lymantria dispar, on quaking aspen, Populus tremuloides, is strongly affected by foliar concentrations of phenolic glycosides. Because the microbial insecticide Bacillus thuringiensis is widely used against gypsy moths and has a mode of action similar to that of phenolic glycosIdes, we investigated the combined effects of the two toxins on gypsy moth larvae. The experimental design was a 2 x 2 factorial: two levels (0, +) of phenolicglycosides for each of two levels (0, +) of B. thuringiensis. The toxins were incorporated into artificial diets and bioassayed against first and fourth instars. Bacillus thuringiensis and phenolic glycosides ne~atively and addi· tively affected larval survival, growth and development tImes. Both agents slightly reduced consumption rates. In addition, B. thuringiensis reduced diet digestibility whereas phenolic glycosides decreased the efficiency with which food was converted to biomass. These results suggest that the efficacy of B. thuringiensis applications in aspen forests is likely to be affected by the allelo· chemical composition of foliage
