Mark Kopytman - Voices of Memories: Essays and Dialogues, ed. Yulia Kreinin, Israel Music Institute, Tel Aviv, 2004, 288 p. A Doctor of Medicine who is also a composer is a rarity. A composer who is also a Doctor of Medicine is even rarer. Dr. Med. Mark Kopytman, however, is above all a composer, and one of Israel´s foremost contemporary composers at that. "Mark Kopytman - Voices of Memories" is a Festschrift - a volume of collected essays edited by Yulia Kreinin, to celebrate his 70th birthday. It is a formidable literary monument to honour this outstanding personality

Monolithic integration of an injection laser and a metal semiconductor field effect transistor

A new laser structure, the "T-laser", has been monolithically integrated with a MESFET on a semi-insulating GaAs substrate. Integration is achieved by means of a compatible structure in which the optically active layer of the laser also serves as the electrically active layer of the MESFET. Direct modulation of the laser by means of the transistor is demonstrated

Poems of the Five Mountains

This second, revised edition of a pioneering volume, long out of print, presents translations of Japanese Zen poems on sorrow, old age, homesickness, the seasons, the ravages of time, solitude, the scenic beauty of the landscape of Japan, and monastic life. Composed by Japanese Zen monks who lived from the last quarter of the thirteenth century to the middle of the fifteenth century, these poems represent a portion of the best of the writing called in Japanese gozan bungaku, “literature of the five mountains.” “Five mountains” or “five monasteries” refers to the system by which the Zen monasteries were hierarchically ordered and governed. For the monks in the monasteries, poetry functioned as a means not only of expressing religious convictions and personal feelings but also of communicating with others in a civilized and courteous fashion. Effacing barriers of time and space, the practice of Chinese poetry also made it possible for Japanese authors to feel at one with their Chinese counterparts and the great poets of antiquity. This was a time when Zen as an institution was being established and contact with the Chinese mainland becoming increasingly frequent—ten of the sixteen poets represented here visited China. Marian Ury has provided a short but substantial introduction to the Chinese poetry of Japanese gozan monasteries, and her translations of the poetry are masterful. Poems of the Five Mountains is an important work for anyone interested in Japanese literature, Chinese literature, East Asian Religion, and Zen Buddhism

GaAs-GaAIAs injection lasers on semi-insulating substrates using laterally diffused junctions

Low‐threshold GaAs‐GaAlAs lasers operating in a stable single mode have been fabricated using laterally diffused junctions. The lasers are fabricated on semi‐insulating substrates and can be integrated with other components

Integration of an injection laser with a Gunn oscillator on a semi-insulating GaAs substrates

The integration of an injection semiconductor laser with an active electronic device (Gunn oscillator) in a single epitaxial crystal device is demonstrated

High-speed GaAlAs/GaAs p-i-n photodiode on a semi-insulating GaAs substrate

A high-speed, high-responsivity GaAlAs/GaAs p-i-n photodiode has been fabricated on a GaAs semi-insulating substrate. The 75-µm-diam photodiode has a 3-dB bandwidth of 2.5 GHz and responsivity of 0.45 A/W at 8400 Å (external quantum efficiency of 65%). The diode is suitable for monolithic integration with other optoelectronic devices

Training Lay Preachers to Preach Expository Sermons in the Wesleyan Church in the Amazon District of Brazil

There is an urgent need for lay preachers to know how to divide the Word of God and preach biblical sermons. This project addresses lay preachers’ needs in the Wesleyan Church in the Amazon district who carry out their significant ministry without any training. The purpose of this project is to supply practical training and to offer a viable preaching model to continue to preach expositional sermons. Action research methods will be used. There will be surveys, interviews, and evaluations done to help and understand the lay preacher. Triangulation will be used by comparing information from the researcher, the research participants, and an outside observer to see if the training method is viable. Quantitative measures will also be used to collect data to understand who the lay preacher is in the Wesleyan Church. Through the data received, this research project seeks to show that lay preachers, in their busy lifestyle, can feasibly gain practical training to preach biblical sermons with confidence. After the training took place the evaluations showed that the lay preachers applied the principles learned and preached effective expository sermons. The model presented is viable. The participants expressed the desire to continue preaching biblical sermons using the methods taught and meeting with other preachers to perfect these skills

Very high frequency GaAlAs laser field-effect transistor monolithic integrated circuit

A very low threshold GaAlAs buried heterostructure laser has been monolithically integrated with a recessed structure metal-semiconductor field-effect transistor on a semi-insulating substrate. At cw operation, the device has a direct modulation bandwidth of at least 4 GHz

Monolithic optoelectronic integration of a GaAlAs laser, a field-effect transistor, and a photodiode

A low threshold buried heterostructure laser, a metal-semiconductor field-effect transistor, and a p-i-n photodiode have been integrated on a semi-insulating GaAs substrate. The circuit was operated as a rudimentary optical repeater. The gain bandwidth product of the repeater was measured to be 178 MHz
