Research has shown that the introduction of health information systems (HISs) can reduce the likelihood of medical errors. However, there is a growing body of evidence that suggests that if it is not designed or implemented properly, a HIS can actually cause or induce health professionals to make medical errors (i.e., technology-induced errors). In order to maximize the benefits of HISs while d...

The structural gene for histidyl-tRNA synthetase was localized to 53.8 min on the Escherichia coli genome. The gene order in this region was determined to be dapE-purC-upp-purG-(guaA, guaB)-hisS-glyA.

Abstract Unexpected short patches of natural VLF emissions at f > 5 kHz have been observed the ground station Kannuslehto (KAN, L ~ 5.5) in Northern Finland. In contrast with usual (e.g., chorus, hiss, and quasiperiodic emissions) these high-frequency bursty-patches are frequencies higher than half equatorial electron gyro-frequency shell KAN. Moreover, most waves reached above local gyrofre...

این پژوهش با الهام گرفتن از نتایج یک طرح مطالعاتی کاربردی، رویکرد سلسله­‌مراتبی جهت پیگیری فرایند توسعه تأمین‌کنندگان و حمایت تصمیمات موجود در هر مراحل آن ارائه‌ می‌کند. ابتدا، زمینه‌های تأمین نیازمند سپس واجد شرایط هریک زمینه‌ها به کمک تصمیم‌گیری چندشاخصه بهترین-بدترین مشخص می‌گردند. معیارهای شناسایی نیز مرور مطالعات پیشین بهره‌گیری نظرات خبرگان حوزه‌ی خرید استخراج‌شده‌اند. درنهایت، مدل ریاضی ...

This paper considers the problem of scheduling a given number of jobs on a specified number of identical parallel robots with unequal release dates and precedence constraints in order to minimize mean tardiness. This problem is strongly NP‐hard. The author proposes a hybrid intelligent solution system, which uses Genetic Algorithms and Simulated Annealing (GA+SA). A genetic ...
