dear editor,i read with interest article that published entitled *isolation and identification of bioactive compound producing rhodococcus spp. isolated from soil samples {ijmcm/5(1) (2015) 463-468}* [1]. some of the genus such as nocardia, gordonia, mycobacterium and rhodococcus are in actinomycete family and they are gram-positive and partially acid-fast. rhodococcus species usually stain gra...

Discontinuous molecular dynamics simulations, together with the protein intermediate resolution model, an intermediate-resolution model of proteins, are used to carry out several microsecond-long simulations and study folding transition and stability of alpha-de novo-designed proteins in slit nanopores. Both attractive and repulsive interaction potentials between the proteins and the pore walls...

The design of retaining walls depends on the magnitude of active pressure exerted from the backfill. Therefore, estimating the scale of this pressure is a fundamental factor in the design. In this study, to assess the active earth pressure, a rigid retaining wall was built capable of translating and/or rotating with adjustable speed. Further, several physical tests were conducte...

We explore the formation of dusty gas walls induced by a circumnuclear starburst around an active galactic nucleus (AGN). We concentrate our attention on the role of the radiation force by a starburst as well as an AGN, where the effects of optical depth of dusty gas are taken into consideration. First, we solve the hydrostatic equations in spherical symmetry coupled with the frequency-dependen...

Recently, we have suggested a model of adsorption in pores with amorphous and microporous solids walls, named the quenched solid density functional theory (QSDFT), that had been successfully applied to modeling adsorption in pores of siliceous materials [1]. This novel approach, which takes into account roughness and corrugation of pore walls, has been extended to carbon adsorbents. QSDFT repre...

The linear polymer chains were approximated as series of identical segments on a simple cubic lattice. The excluded volume was included into the model with no attractive interactions which corresponded to the good solvent conditions. The polymer chains were put into a slit formed by a pair of parallel surfaces. These walls were impenetrable for polymer segments and no other interactions between...

To allow rhizobial infection of legume roots, plant cell walls must be locally degraded for plant-made infection threads (ITs) to be formed. Here we identify a Lotus japonicus nodulation pectate lyase gene (LjNPL), which is induced in roots and root hairs by rhizobial nodulation (Nod) factors via activation of the nodulation signaling pathway and the NIN transcription factor. Two Ljnpl mutants ...
