Free-radical scavenging capacity and antioxidant properties of some selected onions (Allium cepa L.) and garlic (Allium sativum L.) extracts

open access: yesBrazilian Archives of Biology and Technology, 2005
The radical scavenging activity (RAS), chain-breaking activity, H2O2-scavenging, reducing capacity and total phenolics of four types of onions (Green onion, Yellow, Red and Purple) and garlic were investigated.

Spring-loaded Winch Band Brakes as Tools to Improve Safety During Mooring Operations on Ships [PDF]

open access: yesTransNav, 2020
Some recent accident reports involving large vessels in mooring operations or breaking away from their moorings conclude that brakes of mooring winches do not render before line parts.

Breaking Capacity Test of 126kV/2500A/40kA Double Breaks Vacuum Circuit Breaker

open access: yesInternational Journal of Control and Automation, 2016
High-voltage vacuum circuit breakers are intended for breaking the short-circuit current, and the breaking capacity is the major performance indicator. In the paper, the Weil synthetic circuit was built, and by using unit testing method and referring to standard GB/T 1984-2014, the breaking capacity of 126kV/2500A/40kA double-break vacuum circuit ...

Breaking Cournot: The Effects of Capacity-Adjusting Technology

open access: yesJournal of Risk and Financial Management, 2022
The technological improvements modeled for Cournot competition have primarily focused on production cost reductions and scope effects. We consider a case where the technology improves the ability to affect the production capacity constraints instead.

Temperature modes of the contactor contacts during the test for the limiting breaking capacity [PDF]

open access: yesE3S Web of Conferences, 2020
The processes of electric arc quenching of an electromagnetic contactor during testing for ultimate breaking capacity are considered. The conditions for facilitating the successful arc quenching when turning off the limiting currents are shown: by ...

Network Information Flow in Small World Networks [PDF]

open access: yes, 2006
Recent results from statistical physics show that large classes of complex networks, both man-made and of natural origin, are characterized by high clustering properties yet strikingly short path lengths between pairs of nodes. This class of networks are

Directed percolation effects emerging from superadditivity of quantum networks

open access: yes, 2011
Entanglement indcued non--additivity of classical communication capacity in networks consisting of quantum channels is considered. Communication lattices consisiting of butterfly-type entanglement breaking channels augmented, with some probability, by ...
