TO THE EDITOR—How does the global community gain more traction in an effort to combat multidrug-resistant (MDR) tuberculosis globally? We have considered whether it would be helpful to address MDR tuberculosis as a separate epidemic. We introduced the idea because the dominant strategy globally for the past 2 decades has been based on the premise that MDR tuberculosis could be controlled by str...

In this perspective we describe examples of crosstalk between nuclear receptors (NRs) and Notch signaling by means of direct functional interactions between components of both pathways. This crosstalk may provide eukaryotic organisms with molecular mechanisms for the coordination of llong-distance endocrine signals with cell-to-cell juxtacrine communication.

The objective of this paper to present the recent development in the field of gear failure analysis. By the help of this paper we can know about different types of failure detection and analyzing techniques which is used to reduce these failures from gears. The basic reasons of gear failure misalignment of gear, spalling, pitting etc, follow the reason of gear failure. which is identified from ...

The existence of a primitive element of GF (q) with certain properties is used to prove that all cycles that could theoretically be embedded in AG(2, q) and PG(2, q) can, in fact, be embedded there (i.e. these planes are ‘pancyclic’). We also study embeddings of wheel and gear graphs in arbitrary projective planes.

In practical use, most gears have an involute shape of tooth flanks. However, external some drawbacks, such as unfavourable kinematic conditions at the beginning and end meshing, a limited minimum number teeth, highly loaded convex-convex (i.e., non-conformal) contact. Researchers developed analysed various non-involute forms flanks, but they not been widely accepted. The main reasons are highe...
