In this experiment, pyrophyllite as the main materials used the flame photometer to measure adsorption. Using the qualitative analysis of the samples of XRD with internal structure and found that pyrophyllite used in the experiment as a natural mineral, the presence with other minerals. Meanwhile, scanning electron micrographs (SEM) from the display showed that the effect of pyrophyllite adsorption for cations should be more significant. Therefore, this experiment focused on the time, Na+ concentration, on the pyrophyllite and different pyrophyllite concentrations (adsorbent dosage) effect on the adsorption, in addition to the adsorption dynamics. The results showed that pyrophyllite adsorption sodium in the best time of equilibrium was 20 minutes, the concentration of NaCl was 50 mg/L, pH = 7, temperature was 313 K, the concentration of pyrophyllite was 5 mg/L.

The Way

This article applies the theory of possible worlds to the field of translation studies by examining the narrative worlds of original and translated texts. Specifically, Marie-Laure Ryan’s characterization of possible worlds provides an account of the internal structure of the textual universe and the progression of the plot. Based on this account, one of the stories from Rumi’s Masnavi is compared to Coleman Barks’s English translation. The possible worlds of the characters and the unfolding of the plots in both texts are examined to assess the degree of compatibility between the textual universes of the original and the translated texts and how significant this might be. It also examines how readers reconstruct the narrative worlds projected by the two texts. The analysis reveals some inconsistencies in the way the textual universes of the original and translated texts are furnished and in the way readers reconstruct the narrative worlds of the two texts. The inability of translation to fully render the main character results in some loss in terms of the pungency and pithiness of the original text. It is also shown that the source text presents a richer domain of the virtual in comparison, suggesting a higher degree of tellability in the textual universe of the Masnavi’s narrative.

AbstractISHTAR (Internal Structure High-resolution Tomography by Asteroid Rendezvous) is a mission developed through ESA General Studies programme. The study, led by Astrium in cooperation with several scientific institutes throughout Europe, has produced a spacecraft design capable of performing multiple asteroid rendezvous and to characterize them with a focussed set of instruments. The ISHTAR concept is centred around a Radar Tomography paylod able to probe the internal structure of a small asteroid to depths of few hundred meters, combined with a small camera for investigation of the surface properties and a radio science experiment for gravity field measurement. This combination will allow the first detailed characterization of a NEO and will give valuable insights into the origin and evolution processes that govern the NEO population. In particular, ISHTAR will be able to visit at least 2 NEOs belonging to two different spectral classes, thereby allowing us to probe the diversity of the NEO population.

Semantic headedness typically serves as the primary criterion for compound endocentricity, i.e. whether a compound has a head. The semantic head is often defined as the hyperonym from which the denotation of the compound is derived, with exocentric compounds being those whose denotation is not a subclass of that of their head element. Headedness, so defined, leads us to analyze every non-compositional compound as exocentric. We explore the boundaries between semantic exocentricity and non-compositionality using established diagnostics in order to decide whether a semantic characterization of headedness is valid, and to determine whether exocentricity and non-compositionality coincide. Assuming a syntactic model of morphological combinatorics we show that exocentricity must be defined configurationally, occurring when the structure of a compound modifies an external entity, frequently instantiated by an empty noun. Hence exocentricity is not the absence of a head, but the realization of the compound's head outside its internal structure. Non-compositionality, in turn, derives from how the root of each constituent member of a compound is compositionally or idiosyncratically interpreted. Finally, we put forth a new typological distribution of exocentric compounds, discriminating real exocentric compounds (bahuvrihi and dvandva) from compounds that are commonly, but wrongly, defined as exocentric (e.g. deverbal and de-prepositional compounds).

AbstractUnderstanding the morphological structure of membranes is essential to improve performance of membrane-based applications. In this paper, macroporous membranes were investigated and two methods introduced as an alternative for characterization of stereo-structure of the membranes. We combined the use of synchrotron X-ray nanotomography and small-angle X-ray scattering to examine the internal structure of cellulose acetate membranes with studies of the capture of surface-modified gold nanoparticles within these membranes. Finally, the morphological structures of macroporous membranes were visualized and their relationships with penetration tendency of surface-modified gold nanoparticles were explained.
