Notes on the genus Pileolaria (Pucciniales)
The results showed that Pileolaria terebinthi, type species of the genus Pileolaria is not a hemi–form or brachy–form rust species as mentioned among literature by several authors. Study on miscellaneous specimens collected from Iran and locus classicus of the species, France, revealed that P. terebinthi is an automacrocyclic rust and its aecial state is not uredinioi...
متن کاملNotes About Comparing Long-term Care Expenditures Across Countries; Comment on “Financing Long-term Care: Lessons From Japan”
The comparison of long-term care (LTC) expenditures is a difficult task. National LTC systems differ widely in terms of eligibility criteria, level of benefits, institutional variety and regional heterogeneity. In this commentary I will first give some general remarks on cross country comparisons. Then I discuss the role of the informal sector which is the most importan...
متن کاملA scalarization-based method for multiple part-type scheduling of two-machine robotic systems with non-destructive testing technologies
This paper analyzes the performance of a robotic system with two machines in which machines are configured in a circular layout and produce non-identical parts repetitively. The non-destructive testing (NDT) is performed by a stationary robotic arm located in the center of the circle, or a cluster tool. The robotic arm integrates multiple tasks, mainly the NDT of the part and its transition bet...
متن کاملOptimum Design of Interbasin Pipe System (RESEARCH NOTES)
Pipe systems are often used to transfer moderate to medium water volumes between reservoirs or from well fields to consumers. Such systems consisting of an arbitrary number of reservoirs or other types of sources and sinks are considered here. The Lagrangean optimization principle is used for the determination of all pipe diameters giving minimum total cost of the system, when the individual di...
متن کاملNotes on Dictyuchus species (Stramenopila, Oomycetes) from Anzali lagoon, Iran
Nine Dictyuchus isolates were obtained from floating and decaying twigs and leaves in Anzali lagoon, Anzali County, Guilan province, Iran. They are interestingly distinguished from current Dictyuchus species by the presence of dictyoid and achlyoid type of zoospore discharge, abundant fusiform and spherical gemma, and the absence of any sexual apparatus. In addition, phylogene...
متن کاملDetermining the Proper compression Algorithm for Biomedical Signals and Design of an Optimum Graphic System to Display Them (TECHNICAL NOTES)
In this paper the need for employing a data reduction algorithm in using digital graphic systems to display biomedical signals is firstly addressed and then, some such algorithms are compared from different points of view (such as complexity, real time feasibility, etc.). Subsequently, it is concluded that Turning Point algorithm can be a suitable one for real time implementation on a microproc...
