Track thermal buckling is one of the primary safety issues continuously welded rail tracks. The lateral track resistance main resisting force against buckling, which mainly provided through interaction sleepers in ballast material. In this sense, researchers have focused on determining various types material tie push tests; yet implications these results temperature not been fully addressed. ai...

After a short review of the theoretical tools available to describe heavy flavour physics I sketch the present profile of the weak dynamics of charm hadrons with respect to lifetimes, oscillations and CP violation. I argue that comprehensive studies of charm decays provide novel portals to New Physics and suggest some benchmark figures for desirable sensitivities.

Alternative sleeper technologies have been developed to address the significant need for replacement of deteriorating timber railway sleepers. The review literature indicates that sleepers might fail while in service, despite passing evaluation tests current composite standards which indicated these do not represent situ on ballast. In this research, a new five-point bending test is evaluate fl...

One of the safety-critical components ballasted track systems is railway sleepers whose main functions are to (i) transfer vertical load, (ii) maintain rail gauge, and (iii) restrain longitudinal movement. Railway can be manufactured using timber, concrete, steel, composite, any other engineered materials. Prestressed concrete most commonly used type worldwide because their superior value-for-m...

In the modern world, when problems of environment are most acutely associated with climate change, amphibians considered to be vulnerable group anamniotes as an indicator state wetlands. Along a decrease numbers among in Europe, nowadays newts especially suffer from impact invasive species, particular predators such Chinese sleeper, Perccottus glenii. This predatory fish species has recently sp...

Tubulin modifications are emerging as interesting mechanisms to regulate microtubule dynamics. A new study shows that phosphorylation of α-tubulin by the atypical kinase PHS1 leads to rapid disassembly of cortical microtubules in plant cells that are under hyperosmotic stresses.

This contribution adopts the taxonomic concept annotation and alignment approach. Accordingly, and where indicated, previous and newly inferred meanings of taxonomic names are individuated according to one specific source. Articulations among these concepts and pairwise, logically consistent alignments of original and revisionary classifications are also provided, in addition to conventional no...

Multiscale modeling for cement-based materials, such as concrete, is a relatively young subject, but there are already a number of different approaches to study different aspects of these classical materials. In this paper, the parameter-passing multiscale modeling scheme is established and applied to address the multiscale modeling problem for the integrated system of cement paste, mortar, and...

The development of native fish aquaculture represents an important alternative to mitigate ecological displacement generated by exotic fish. introduction in polyculture systems with high commercial value fishes has provided a useful strategy for sustainable development. present study aims provide information on tilapia, as species, and Dormitator latifrons, duo culture not programmed such. Usin...
