OBJECTIVE To explore and compare nutrition knowledge, attitudes and behaviours (KAB) between non-parent and parent caregivers of children under 7 years old in Chinese rural areas, and to identify the factors influencing their nutrition KAB. DESIGN Face-to-face interviews were carried out with 1691 non-parent caregivers and 1670 parent caregivers in the selected study areas; multivariate logis...

This property can be exploited (see [Boy90] or [SG92] for other instances) to flaw the Needham-Schroeder symmetric key authentication protocol [NS78]. This protocol intends to permit Alice to establish a shared secret key Kab with Bob and to obtain mutual conviction of the possession of the key by each other. The key is provided by a trusted server S who shares the secret keys Kas and Kbs with ...

The authors attempted to determine whether a targeted educational intervention in an area with endemic Lyme disease could increase knowledge, positive attitudes, and reported behaviors related to tick bite prevention and consequently decrease tick bites, as measured by a biomarker of tick bites. Between April and September of 1999, 317 subjects in Baltimore County, Maryland, were randomized to ...

Cochlear endolymph has a highly positive potential of approximately +80 mV. This so-called endocochlear potential (EP) is essential for hearing. Although pivotal roles of K+ channels in the formation of EP have been suggested, the types and distribution of K+ channels in cochlea have not been characterized. Because EP was depressed by vascular perfusion of Ba2+, an inhibitor of inwardly rectify...

We present a semiclassical calculation of the generalized form factor Kab(tau) which characterizes the fluctuations of matrix elements of the operators a and b in the eigenbasis of the Hamiltonian of a chaotic system. Our approach is based on some recently developed techniques for the spectral form factor of systems with hyperbolic and ergodic underlying classical dynamics and f = 2 degrees of ...

This document reports on the activities related to Task 2.4: Techniques and Tools for KAB, to Manage Action Linkage with Artifact Layer, which is part of Workpackage 2 within the ACSI project. In particular, it describes the results of the second iteration of Task T2.4. The main goal of this activity is to tackle the key issues for actually realizing the Knowledge and Action Base (KAB), by marr...

In bacterial reaction center of Rhodobacter sphaeroides, Cd2+ binds in stoichiometric amount to the protein. In the wild type, this results into a notable decrease of the rates of electron-transfer between the two quinone acceptors after the first (kAB(1)) and second flash (kAB(2)). We have studied these effects in two single mutants, L209PY and L209PF. L209Pro is situated in a protein region r...

The reaction center (RC) from Rhodobacter sphaeroides converts light into chemical energy through the reduction and protonation of a bound quinone molecule QB (the secondary quinone electron acceptor). We investigated the proton transfer pathway by measuring the proton-coupled electron transfer, kAB [QA.QB. 1 H13 QA(QBH)] in native and mutant RCs in the absence and presence of Cd21. Previous wo...

Lower extremity injuries are the most common injuries for occupants in frontal crashes and account for 45% of all AIS 2+ injuries. Although knee airbags (KAB) have been shown to reduce knee,thigh and hip injuries, their effectiveness as a countermeasure for tibia, foot and ankle injuries remains unclear. A review of 29 frontal crash cases from the Crash Injury Research and Engineering Network (...

In the classic Diffie-Hellman protocol based on a generic group G, Alice and Bob agree on a common secret KAB (master secret) which is indistinguishable from another element of G but not from a random bits-string of the same length. In this paper, we present a new deterministic method to extract bits from KAB when G is an elliptic curve defined over a quadratic extension of a finite field. In t...
