Nanoparticle crystals or superlattices (SLs) are three dimensional arrangements of nanoparticles in the micrometre regime. In SLs, the particles are periodically arranged in a coherent long range order and hence they show collective properties. Various spectroscopic, scattering and imaging techniques have been used to understand the structure of self-assembled SLs. Extensive interest in particl...

The simultaneous application of ultrasound and the surfactant sodium lauryl sulfate (referred to as US/SLS) to skin enhances transdermal drug delivery (TDD) in a synergistic mechanical and chemical manner. Since full-thickness skin (FTS) and split-thickness skin (STS) differ in mechanical strength, US/SLS treatment may have different effects on their transdermal transport pathways. Therefore, w...

time instant the evolving LS. Hybrid systems cap­ ture the continuous and discrete interaction that appears in complex systems ranging from biolog­ ical systems [14] to automotive systems [7]. For SLS, many contributions have been reported con­ cerning such basic system properties as stability, controllability, and observability. Since the conditions for the observability with unknown inputs of...

BACKGROUND The irritant sodium lauryl sulfate (SLS) is known to cause a decrease in the stratum corneum level of natural moisturizing factor (NMF), which in itself is associated with changes in corneocyte surface topography. OBJECTIVE To explore this phenomenon in allergic contact dermatitis. METHODS Patch testing was performed on patients with previously positive patch test reactions to po...

BACKGROUND Strigolactones (SLs) - a group of plant hormones and their derivatives - have been found to play a role in the regulation of root development, in addition to their role in suppression of lateral shoot branching: they alter root architecture and affect root-hair elongation, and SL signalling is necessary for the root response to low phosphate (Pi) conditions. These effects of SLs have...

Stochastic local search (SLS) techniques are very effective in solving hard propositional satisfiability problems. This has lead to the popularity of the encode & solve paradigm in which different problems are encoded as propositional satisfiability problems to which SLS techniques are applied. In AI, planning is the main area in which this methodology is used. Yet, it seems plausible that SLS ...

The purpose of this study is to investigate feasibility of sodium lauryl sulfoacetate (SLS) as an immunoadjuvant in chickens. After treating with 62.5, 125, 250, or 500 mug/mL SLS in vitro, lymphocyte proliferation assay of chicken peripheral blood mononuclear cells showed that the OD(570) values of all experimental groups, as well as Con A-stimulated group, were significantly higher than that ...

Selective laser sintering (SLS) of metals is a complex process exhibiting multiple modes of heat, mass and momentum transfer, and chemical reactions. The strong interplay between these physical mechanisms directly impacts the SLS process, determining whether a given material can be processed and if so, how the microstructure and properties of the processed material are in uenced. In order to un...

Major strigolactones (SLs) produced by rice (Oryza sativa L. cv. Nipponbare) and tobacco (Nicotiana tabacum L. cv. Michinoku No. 1) were purified and their stereochemical structures were determined by comparing with optically pure synthetic standards for their NMR and CD data and retention times and mass fragmentations in ESI-LC/MS and GC-MS. SLs purified from root exudates of rice plants were ...

A dual-beam surface-layer scintillometer (SLS) was used to estimate sensible heat flux (H) every 2 min for a path length of either 50 or 101 m, for more than 30 months in a mesic grassland in eastern South Africa. The SLS method relies on Monin-Obukhov similarity theory, the correlation between the laser beam signal amplitude variances and the covariance of the logarithm of the beam signal ampl...
