OBJECTIVE The purpose of this investigation was to examine the microbiota of infected root canals by using a molecular genetic method. STUDY DESIGN The presence and levels of 42 bacterial species were determined in 28 root canal samples by using whole genomic DNA probes and checkerboard DNA-DNA hybridization. To confirm the presence of bacterial DNA in clinical samples, a polymerase chain rea...

Surface Detail: We have discussed the use of lighting as a method of producing more realistic images. This is fine for smooth surfaces of uniform color (plaster walls, plastic cups, metallic objects), but many of the objects that we want to render have some complex surface finish that we would like to model. In theory, it is possible to try to model objects with complex surface finishes through...

In prior work, the authors developed a method of degenerate perturbation theory about the Ising limit to derive an effective Hamiltonian describing quantum fluctuations in a half-polarized magnetization plateau on the pyrochlore lattice. Here, we extend this formulation to an arbitrary lattice of corner sharing simplexes of q sites, at a fraction (q − 2k)/q of the saturation magnetization, with...

Interaction between amphotericin B and metronidazole was studied against Candida albicans, Candida tropicalis, Candida parapsilosis, Candida krusei, and Candida lusitaniae strains. Minimum inhibitory concentrations (MICs) of the drugs alone and in combination were determined by means of the checkerboard method on YNB supplemented agar. Minimum fungicidal concentrations (MFCs) were determined on...

The aim of the present study was to evaluate the effect of cotrimoxazole on the in vitro susceptibility of Coccidioides posadasii strains to antifungals. A total of 18 strains of C. posadasii isolated in Brazil were evaluated in this study. The assays were performed in accordance with the Clinical and Laboratory Standards Institute guidelines and the combinations were tested using the checkerbo...

Bu çalışmanın amacı, punikalaginin tek başına ve kolistin ile kombinasyon halinde antimikrobiyal aktivitesini kolistine dirençli A. baumannii suşları üzerinde değerlendirmektir. Çalışmada test edilmek üzere beş adet suşu kullanılmıştır. Suşlara karşı punikalagin kolistinin aktivitelerini saptamak için sıvı mikrodilüsyon testi yapılarak Minimum İnhibisyon Konsantrasyonları (MİK) belirlenmiştir. ...

Abstract By means of the first-principles calculations and magnetic topological quantum chemistry, we demonstrate that low-energy physics in checkerboard antiferromagnetic (AFM) monolayer FeSe, very close to an AFM insulator hosts robust edge states, can be well captured by a double-degenerate nearly flat band with fragile topology just below Fermi level. The Wilson loop identify such is protec...

New sufficient conditions for strong approximation of copulas, generated by sequences of partitions of unity, are given. Results are applied to the checkerboard and Bernstein approximations.

In this paper we study the thermodynamics of the one dimensional continuum analogue of the Falicov-Kimball model in the strongly correlated limit using a method developed by Salsburg, Zwanzig and Kirkwood for the Takahashi gas. In the ground state it is found that the f electrons form a cluster. The effect of including a Takahashi repulsion between f particles is also studied where it is found ...
