The inclusion compound of urea with hexadecane has a superstructure of an ideal hexagonal structure found in other members of the series of urea-n-paraffin adducts consisting essentially of honeycomb-like channels formed by the host into which the long chain molecules are embedded. In order to elucidate the nature of the superstructure, which manifests itself by addiditonal weaker reflexions ( ...

The asset management and Life Cycle Costing (LCC) principals perform a vital role in the reduction and optimization of the costs of an infrastructure manager, providing a better decision support technically and financially. It was intended to create an asset management LCC model to rail track superstructure of the Portuguese rail network assembled with the Iberian gauge. This model is able to r...

In this paper, pile behavior embedded in layered soil deposits subjected to seismic loadings is analyzed using a nonlinear fiber element for simulation of soil – pile interactions. In the created model, both pile and surrounding soil are modeled using fiber elements in a practical Beam on Nonlinear Winkler Foundation (BNWF) concept. Herein, the features of DRAIN–3DX finite element software are ...

Construction of a rose-like hierarchical superstructure composed of rare-earth hydroxide nanosheets and polyoxomolybdates, which was achieved by the self-assembly at room temperature, led to a drastically enhanced photoluminescence.

A novel 21-residue peptide incorporating six fluorinated amino acids was prepared. It was designed to fold into an amphiphilic alpha helical structure of nanoscale length with one hydrophobic face and one fluorinated face. The formation of a fluorous interface serves as the main vector for the formation of a superstructure in a bilayer membrane. Fluorescence assays showed this ion channel's abi...

The formation of complex superstructures via hydrogen bonding of two ditopic building blocks, diazadibenzoperylenes 1a,b and isophthalic acid 2, has been investigated. It was found that only the phenoxy-substituted diazadibenzoperylene 1a forms extended assemblies with 2 in complexes of a 1:1 stoichiometry, whereas for the 4-tert-butylphenoxy-substituted analogue 1b, no indications for superstr...

We previously reported the transient appearance of an actin superstructure, called the zipper-like structure, during the primary fusion (fusion of mononuclear precursors) and the secondary fusion (fusion of multinucleated cells) of osteoclasts. Here, we focus on the actin-based superstructures that link two precursor cells during the secondary fusion event. In one type of secondary fusion, the ...

With additional quality modeling features added to conceptual models, computers could play a greater role in ensuring a higher level of quality in the information we model. For information-discovery applications, these additional conceptual modeling features should automatically accommodate certainty and conflicting information, support evidence-based research, automate collaboration, and provi...

For the last few years, molten salt nanomaterials have attracted many scientists for their enhanced specific heat by doping a minute concentration of nanoparticles (up to 1% by weight). Likewise, enhancing the specific heat of liquid media is important in many aspects of engineering such as engine oil, coolant, and lubricant. However, such enhancement in specific heat was only observed for molt...

OBJECTIVES/HYPOTHESIS To review surgical findings and hearing outcomes of incus footplate assembly (IFA) for the patients with conductive hearing loss due to missing stapes superstructure with a mobile stapes footplate. STUDY DESIGN Retrospective case review and survey. METHODS Pre- and postoperative audiometric data and intraoperative findings were reviewed. Postoperative air-bone gap (ABG...
