Interactions between metronidazole and amoxicillin, metronidazole and its hydroxymetabolite, and amoxicillin and the hydroxymetabolite of metronidazole were investigated with checkerboard titrations in combination with accurately determined MICs and MBCs. Actinobacillus actinomycetemcomitans was used as the test organism. Synergism was found for all three combinations. Fractional inhibitory con...

This paper defines underlying performance quality measures for designing, optimizing, setting and evaluating the protective relaying algorithms and equipment. The paper starts with evaluation of digital measuring algorithms, and gradually introduces the performance indices for the operating principles, relays and protection systems. Multi-objective formal ranking methods based on fuzzy set theo...

Considering a forest cover (Balsam Fir with various densities) we analyze the sensitivity of several vegetation indices to ozone absorption using physical simulations in the spectral bands of MODIS, VEGETATION and AVHRR sensors. Except for the EVI, MSR and GARI, the results indicate that all the vegetation indices used in this study normalize the ozone absorption in particular TSARVI and GEMI. ...

In this paper, the issues in load measurement in dynamic load balancing (DLB) algorithms have been explored. We have analyzed various load indices used to estimate the load on the nodes in the system for load balancing algorithms. The simulation model has been used to address performance issues associated with load balancing. The architecture for implementation and performance evaluation of ind...

design of crystal-like lattices can be achieved by using some net operations. hypothetical networks, thus obtained, can be characterized in their topology by various counting polynomials and topological indices derived from them. the networks herein presented are related to the dyck graph and described in terms of omega polynomial and piv polynomials.

This paper was aimed at evaluating the mental work-load (MWL) with psycho-physiological indices. Especially, we focused on the intermittent type of MWL, which is assumed as a predisposing factor of various somatic and mental disorders. In the experiment, we introduced a facial skin thermo image comparing with conventional physiological indices, such as electrocardiogram (ECG) and electroencepha...

Mathematical descriptors of molecular structure, such as various topological indices, have been widely used in structure-property-activity studies (see [5, 6, 12]). Among the numerous topological indices considered in chemical graph theory, only a few have been found noteworthy in practical application (see [10]). One of these is the connectivity index or Randić index. The Randić index of an or...

Background Traditional muscle fatigue indices (Fmean and Fmed) have a relatively low sensitivity under dynamic exercise conditions. Various muscle fatigue indices have been attempted to overcome this problem [1,2]. However, their methods required large amounts of computation and had limitations in time-frequency resolution [3]. Kim et al. introduced the use of a filter-based fatigue index (FIhl...

This paper considers the reliability of an M/G/1 queue with multiple adaptive vacations in which the arriving customers enter the system with probability p (0<p≤1) during vacations. Through appropriate assumptions, the model is studied by the total probability decomposition technique and the tool of Laplace transform. Some reliability indices are studied. Moreover, we give some numerical exampl...
