This paper describes the concepts and rationale of Paros, an operating system microkernel specifically targeted to distributed memory parallel computers. The Paros microkernel has been designed to provide dynamic support for general purpose parallel applications and operating systems under the distributed memory programming model. Fine grain parallelism in machines with large numbers of nodes i...

This experiment was performed to evaluate the effects of different types and concentrations of carbohydrate source on callus fresh weight, number of somatic embryos per embryonic explant and percentage of globular embryos developing into cotyledonary embryos from the leaf explants of three strawberry cultivars (Kurdistan, Paros and Camarosa). MS medium containing 1.0 mg/l 2,4-dichlorophenoxyace...

Abs t r ac t . We give an overview of the parallelization work done in PAROS. The specific parallelization objective has been to improve the speed of airline crew scheduling, on a network of workstations. The work is based on the Carmen System, which is used by most European airlines for this task. We give a brief background to the problem. The two most time critical parts of this system are th...

The role of social capital for socio-ecological systems is undisputed. While fostering cooperation in some communities, however, can also lead to tight control and distrust towards outsiders new practices, contributing the persistence undesirable, unsustainable practices. This paper explores challenges emerging from “dark side” sustainability efforts systems, raising question how they be addres...

Ancient Greek and Roman sources report that the statue of Zeus in Olympia had a head, and in particular eyes, similar to the description of Zeus by Homer, so we think that the statue was visible to the human eye. Since the temple was 12 m high, and had a small door and no windows, the illumination of the statue by conventional media is questionable. The aim of this paper is to characterize the ...

BACKGROUND One of the key principles in the recommended standards is that emergency medical service (EMS) providers should continuously monitor the quality and safety of their services. This requires service providers to implement performance monitoring using appropriate and relevant measures including key performance indicators. In Asia, EMS systems are at different developmental phases and ma...

effects of nitrogen fertilization timing close to the beginning of short-day period and white mulch on flowering and yield components have been studied in ‘paros’ and ‘queen elisa’ strawberry cultivars. split plot experiment in a randomized complete block design with eight treatments (two mulch treatments × n fertilization during four different times from last week of august to third week of se...
