An R plasmid, R100-1, was mapped previously (Yoshikawa, 1974) by transduction from an integratively suppressed Hfr strain to a recipient with a mutation in gene dnaA. By this method various types of transductants of plasmid R100-1 that exist autonomously or in the integrated state were obtained. Seventy-one such transductants were used in the present study to map gene inc, which is responsible ...

All too frequently, a software cost estimate is required in the early stages of the life-cycle when requirements and design specifications are immature. To produce a cost estimate under these conditions requires extensive use of expert judgment and addressing significant estimation uncertainty. Research has shown that expert judgment under the right conditions can yield relatively "accurate" es...

در این کار پژوهشی، نمونه‌های هیدروکسی اپتایت آلاییده با ناخالصی‌های سریم، گادولونیم و ترکیبی از دو ناخالصی به روش هیدروترمال سنتز شدند. منظور بررسی فازهای بلوری تشکیل یافته هرکدام شده، کد MAUD که یک نرم‌افزار برای تجزیه تحلیل ساختار ماده استفاده پراش بر اساس ریتولد است، شد. پاسخ دزیمتری ترمولومینسانس نمونه‌ها مورد قرار گرفت یافته‌ها نشان داد نمونه‌ ترکیبی، سطح میانی است. مشخص شد افزودن سریم می‌...

Introduction “Second best no more” was the title of an article written by David C. Joy for Nature Materials [1]. The article was for highlighting a breakthrough made by a team formed between Brookhaven National Laboratory (BNL, USA) and Hitachi High Technologies Corporation (HHT, Japan). Sub-angstrom secondary electron (SE) images were obtained on a Hitachi HD-2700, which is a combined scanning...

The authors have given us a lucid, concise, and accurate account of the TETRAD project, an account likely to clear much of the confusion over the philosophy of graph-based causal discovery methods. As one who has been active in the exploration and formulation of this philosophy, I am very pleased to see TETRAD arrive at this stage of development and now presented as a practical modeling tool fo...
