Visual shapes inherent in di↵erent aspects of language processing have been manifesting themselves as important not only for enhancing that process itself, but also for helping solve open problems in ways that are more economical and more intuitive than the usual statistical-based, massive processing approaches. In this article we investigate an interesting use of gleaning shape from input sets...
The use of lyphogel to concentrate the number of virus particles in specimens for electron microscopic examination was studied in parallel with ultracentrifugation. One hundred faecal and urine samples were compared. Both methods had a similar sensitivity. Lyphogel was economical, simple, and rapid in use; in contrast to ultracentrifugation, it required relatively little material. The procedure...
A stereoselective bromocyclopropanation of allylic alcohols using dibromomethylzinc bromide is described. Spectroscopic studies to monitor the formation of transient intermediates not only led to the development of a more-atom-economical halocyclopropanation reaction, but also highlighted the unique role of ether additives in the process. The desired bromo-substituted cyclopropanes were isolate...
We report on a highly compact, one diode-one resistor (1D-1R) nanopillar device architecture for SiOx-based ReRAM fabricated using nanosphere lithography (NSL). The intrinsic SiOx-based resistive switching element and Si diode are self-aligned on an epitaxial silicon wafer using NSL and a deep-Si-etch process without conventional photolithography. AC-pulse response in 50 ns regime, multibit ope...
Embedded systems frequently are limited in resources such as memory space and processing power. The limits come from technical (power consumption, space, weight) and economical factors. In the design process it is desirable to achieve information about resource demand as early as possible in order to optimize the design. Unfortunately there is no straight way to calculate such values. The resul...
In this article, I explore the development of modern cremation and cremation events in Norway. I focus on the multiple ontologies of cremation events and the relationships between the living mourners and the dead during the gradual transformation of the social person within Christian, secular as well as Hindu traditions in Norway. Within Christian tradition, this is a linear process that I inte...
BACKGROUND Curcumin and vanillin are the two useful compounds in food and medicine. Bismuth nitrate pentahydrate is an economical and ecofriendly reagent. METHOD Bismuth nitrate pentahydrate impregnated montmorillonite KSF clay and curcumin were subjected to microwave irradiation. RESULTS Microwave-induced bismuth nitrate-promoted synthesis of vanillin from curcumin has been accomplished in...
This study proposes an innovative biodiesel technology based on heat-integrated reactive absorption. Rigorous simulations embedding experimental results were performed in AspenTech AspenONE engineering suite to design this novel process and evaluate the technical and economical feasibility. The main results are given for a plant producing 10 ktpy biodiesel from waste vegetable oil with high fre...
