Non-thermal plasma (NTP) catalysis is a promising technology for CO2 valorization with renewable H2, in which catalyst design one of the key aspects to progress hybrid technology. Herein, bimetallic NiCo supported on CeO2 catalysts, that is, NiCo/CeO2, were developed less metal loading ∼2 wt % using mechanochemical synthesis NTP-catalytic methanation. During synthesis, different addition orders...

provision of services by public sector providers overseen directly by National TB Programs (NTP). However, a majority of people first seek care in the non-NTP sector, even among the very poor [1], and one key reason for the missing millions is the patients who are managed in the informal and private sectors, but either not diagnosed, or not notified to NTPs. The private and informal sector rang...

Location Positioning is a major technology for ubiquitous computing. A research on Location Positioning using UWB is ongoing. In order to construct an indoor location network, synchronization of base stations is very important. NTP is popularly used as a clock synchronization protocol ranging from LAN to WAN. The Master-Slave scheme, however, is the simplest method for synchronizing an indoor n...

The National Toxicology Program (NTP) has announced that it will design and initiate studies to identify and characterize possible adverse health effects that may be associated with prolonged use or higher doses of some of the most popular medicinal herbs, including Ginkgo biloba, Echinacea angustifolia, and Panax quinquefolius (American ginseng). The NTP studies a large variety of substances t...

The U.S. National Toxicology Program (NTP) completed a yearlong research program to evaluate the potential toxicity of chemicals spilled into the Elk River in Charleston, West Virginia. The collected findings of the NTP studies support the adequacy of the drinking water screening level concentrations recommended by the Centers for Disease Control and Prevention (CDC) at the time of the spill. E...

Using a testbed with reference timestamping, we collected timing data from public Stratum-1 NTP servers during the leap second event of end-June 2015. We found a wide variety of anomalous serverside behaviors, both at the NTP protocol level and in the server clocks themselves, which can last days or even weeks after the event. Out of 176 servers, only 61% had no erroneous behavior related to th...

BACKGROUND Public-private partnerships are felt to be necessary for tuberculosis (TB) control in some developing countries. OBJECTIVES To evaluate the potential of a collaboration between the National TB Programme (NTP) and private pharmacies in Bolivia, the country with the highest TB incidence in Latin America. METHODS We contacted the local Pharmacists' Association in the city of Cochaba...

A compilation is presented of viral proteins containing the NTP-binding sequence pattern, and criteria are suggested for assessment of the functional significance of the occurrence of this pattern in protein sequences. It is shown that the distribution of NTP-binding pattern-containing proteins through the viral kingdom is strongly non-random. Sequence comparisons led to delineation of several ...

This paper describes a series of experiments involving over 100,000 hosts of the Internet system and located in the U.S., Europe and the Pacific. The experiments are designed to evaluate the availability, accuracy and reliability of international standard time distribution using the DARPA/NSF Internet and the Network Time Protocol (NTP), which is specified as an Internet Standard in RFC-1119. N...
