The business of supporting legacy electronic systems is challenging due to mismatches between the system support life and the procurement lives of the systems’ constitute components. Legacy electronic systems are threatened with DMSMS-type obsolescence (Diminishing Manufacturing Sources and Material Shortages) and the knowledge of their system support lives based upon existing replenishable and...

the harvest date more influenced on postharvest quality during storage. in present study, fruits were harvested at four date base on total soluble solids content (5.5, 6.5, 7.5, and 8.5%) and then stored at 0.5 ºc and 80-90% rh, for 18 weeks. the samples were taken in 6th, 12th and 18th interval weeks and evaluated some parameters including weightless, losses, firmness, tss, ta, tss/ta, ascorbi...

The object of this study was evaluation of a walking tractor drawn peanut harvester at different conditions of soil moisture content and forward speed and comparing it with manual harvesting. The evaluation factors for peanut harvester were two levels of soil moisture content and three levels of forward speed. The results revealed that the effect of soil moisture content was only significant on...

BACKGROUND In coronary artery bypass grafting surgery, arterial conduits are preferred because of more favourable long-term patency and outcome. Anyway the greater saphenous vein continues to be the most commonly used bypass conduit. Minimally invasive endoscopic saphenous vein harvesting is increasingly being investigated in order to reduce the morbidity associated with conventional open vein ...

Results We present global planting date patterns for maize, spring wheat and winter wheat (our full, publicly available data set contains planting and harvesting dates for 19 major crops). Maize planting in the northern mid-latitudes generally occurs in April and May. Daily average air temperatures are usually c. 12–17 °C at the time of maize planting in these regions, although soil moisture of...

This paper describes a distributed registry of XML Schemas in which a central facility uses the Open Archives Protocol for Metadata Harvesting (OAI-PMH) as a communication mechanism between registrars and parties that need to remain up-to-date regarding registration, updating and deregistration of those Schemas. This novel application of the OAI-PMH is described in the context of registration o...

Quinoxaline-based semiconducting materials are currently of high interest in the field of organic photovoltaics. The number of structural variations employed has been, however, quite limited to date. In this paper we report on the synthesis of a series of quinoxaline monomers and triads with improved optical features. This was achieved by using conjugated linkers, i.e. ethenyl, butadienyl and/o...
