PURPOSE The purpose of this preliminary study was to examine the relationship of caries risk, salivary buffering capacity, salivary pH, salivary quality (flow, consistency) and levels of Streptococcus mutans in relation to cigarette smoking. METHODS This clinical trial consisted of 53 volunteer patients receiving care in a university based dental hygiene clinic. Participants completed a ques...

Os gestores organizacionais adotam ações que bloqueiam a aproximação com os atores político-sociais (postura buffering) e as criam pontes estratégicas bridging). No entanto, literatura sobre stakeholders fornece informações escassas o envolvimento entre micro pequenas empresas seus públicos. A pesquisa investigou fatores determinantes das atividades buffering bridging em empresas. Utilizando um...

Abstract. MPJ Express is our implementation of MPI-like bindings for Java. In this paper we discuss our intermediate buffering layer that makes use of the so-called direct byte buffers introduced in the Java New I/O package. The purpose of this layer is to support the implementation of derived datatypes. MPJ Express is the first Java messaging library that implements this feature using pure Jav...

We propose and evaluate two complementary techniques to protect and virtualize a tightly-coupled network interface in a multicomputer. The techniques allow efficient, direct application access to network hardware in a multiprogrammed environment while gaining most of the benefits of a memory-basednetwork interface. First, two-case delivery allows an application to receive a message directly fro...

In our previous paper, we have proposed a framework for automatically translating tree-processing programs into stream-processing programs. However, in writing programs that require buffering of input data, a user has to explicitly use buffering primitives which copy data from input stream to memory or copy constructed trees from memory to an output stream. Such explicit insertion of buffering ...

The intracellular non-bicarbonate buffering capacity of vertebrate muscle is mainly supported by the imidazole groups of histidine residues in proteins, free L-histidine in some fish species, and histidine-containing dipeptides such as carnosine, anserine, and balenine (ophidine). The proton buffering capacity markedly differs between muscle types and animal species depending on the ability for...

BACKGROUND Baroreflex buffering is an important mechanism in arterial blood pressure control. The effect of healthy (physiological) aging on tonic baroreflex buffering in humans is unknown. METHODS AND RESULTS Baroreflex buffering was determined in 27 young (aged 25+/-1 years) and 16 older (aged 65+/-1 years) healthy normotensive men by measuring the potentiation of the systolic blood pressur...

A supramolecular system in which the concentration of a molecule is buffered over several orders of magnitude is presented. Molecular buffering is achieved as a result of competition in a ring-chain equilibrium of multivalent ureidopyrimidinone monomers and a monovalent naphthyridine molecule which acts as an end-capper. While we previously only considered divalent ureidopyrimidinone monomers w...

There is increasing evidence that multimedia traffic in a variety of networks including the Internet, exhibits properties of self-similarity such as long-range dependence and a high-degree of correlation between arrivals. The demands of self-similar traffic impose unique new requirements in switch design, especially as far as the buffering strategy is concerned. In this paper, we study buffer s...
