Authors: Haroun Ahmed A. , El Nahrawy Amany M. , Maincent Philipe 
Published: May 2014

AbstractEnoxaparin-immobilized gelatin/poly(ε-caprolactone) (PCL) or Eudragit® RS230D nanogels in the presence of tetraethyl orthosilicate (TEOS) as polycondensation reagent were designed and characterized for their sustained drug delivery ability. Enoxaparin (anti-Xa 1000 UI/mL) was used as a model drug at different concentrations (300, 500, and 1000 UI/mL). The resulting nanogels were prepared using sol-gel technique and analyzed using several analytical tools such as: thermal analysis (DSC and TGA), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning and transmitting electron microscopes (SEM and TEM). In addition to particle size, zeta potential and in vitro release profiles were also investigated. A burst effect was observed, afterwards, the release rate became steady. The immobilization of enoxaparin into the gel network led to the formation of stable nanogels with ionic functional groups, which enable the efficient loading and sustainable release. The preliminary results showed that enoxaparin-immobilized PCL-based nanogels in this study can be utilized in the design of a sustained delivery system.

AbstractA series of thienothiophene-benzotriazole-based semicrystalline copolymers, PTTBTz, PTTBTz-F, and PTTBTz-OR, were synthesized by considering chain linearity, planarity and inter-chain packing by virtue of non-covalent attractive interaction. Fluorine and alkoxy substituents were introduced to modulate the intra- and inter-chain coulombic interactions and crystalline ordering. The fluorine and alkoxy-substituted PTTBTz-F and PTTBTz-OR showed pronounced inter-chain packing with edge-on orientation confirmed by UV-vis absorption and X-ray diffraction measurements. The well-resolved diffraction patterns were obtained for PTTBTz-F and PTTBTz-OR, showing (100)∼(500) inter-lamellar scattering peaks (d-spacing, 17∼18 Å) in the out-of-plane direction and a π-π stacking peak (d-spacing, 3.5∼4.1 Å) in the in-plane direction. Organic field effect transistor (OFET) devices were fabricated with a bottom gate and top contact geometry. PTTBTz-F (μh = 4.49 × 10–2 cm2 V–1 s–1, on/off ratio = 1.13 × 107) and PTTBTz-OR (μh = 8.39 × 10–3 cm2 V–1 s–1, on/off ratio = 2.98 × 104) showed nearly 3 and 2 orders of magnitude higher hole mobility upon annealing at 305 and 260 °C, with compared to the unsubstituted PTTBTz.
Myoblast differentiation on growth factor-immobilized polycaprolactone microparticles: a potential bioactive bulking agent for fecal incontinence
Authors: Ho Kim Tae , Heang Oh Se , Kang Sung Bum , Ho Lee Jin 
Published: May 2014

AbstractFecal incontinence (FI), caused by damage or weakness of the anal sphincter, is a devastating problem for patients experiencing the symptom. Although injectable bulking agents are accepted as a minimally invasive therapeutic technique to treat FI, their short-term efficacy and inability to enhance the anal sphincter function are considered as challenges in clinical practices. In this study, growth factor [nerve growth factor (NGF) and/or basic fibroblast growth factor (bFGF)]-immobilized polycaprolactone (PCL) microparticles were prepared as an injectable bioactive bulking agent that can provide a bulking effect (by microparticles) and stimulate myoblast differentiation or injured muscles around the anus (by the sustained release of growth factors) to enhance the sphincter function for the effective treatment of FI. Pluronic F127-entrapped PCL microparticles were prepared by an isolated particle-melting method. Two different growth factors (NGF and bFGF) were incorporated on the surfaces of the Pluronic F127-entrapped PCL microparticles via heparin binding. The growth factors immobilized on the microparticles were released in a sustained manner over 4 weeks. From cell cultures on the growth factor-immobilized microparticles, it was observed that the myoblasts adhered on the microparticle surfaces showed differences in differentiation into myotubes depending on the growth factor type. In particular, the dual NGF/bFGF-immobilized microparticle group was effective for myogenic differentiation in comparison with the single growth factor (NGF or bFGF)-immobilized groups. The dual NGF/bFGF-immobilized microparticles are suitable to be applied as an injectable bulking agent for the treatment of FI.

Modelling of niobium sorption on clay minerals in
sodium and calcium perchlorate solutions
Authors: Ervanne Heini , Hakanen Martti , Lehto Jukka 
Published: May 2014

Abstract
The sorption behaviour of niobium on kaolinite and illite minerals in sodium and calcium perchlorate solutions was evaluated with use
of the mass distribution coefficient, R
d, obtained in batch sorption experiments. Very high distribution coefficient
values, about 100 m3/kg, were obtained for both minerals in the neutral pH range between 6 and 8. Values were somewhat
lower at pH 5. In NaClO4 solution, the sorption of niobium starts to decrease at pH higher than 8. This is in agreement with
the increase, with pH, in the proportion of anionic niobate species, which are presumed to be low or non-sorbing. A similar decrease
was not observed in Ca(ClO4)2 solution, probably owing to the influence of Ca on niobium solution speciation and surface
species. The surface complexation model was applied to model the R
d values. The model fitted well for the NaClO4
solution but only at pH below 9 for the Ca(ClO4)2 solution. The discrepancy between the strong sorption of niobium in
calcium-bearing solution at high pH and the calculated speciation is due in part to the non-inclusion of calcium niobate solution
species and Ca-Nb compounds in the present NEA and other similar thermodynamic databases.

Published: May 2014

Abstract
A method is proposed for production of polonium-210 via the 209Bi(α, 3n)210At nuclear
reaction. Bombardment of a bismuth-209 target was performed with a 37 MeV alpha-particle beam that leads to the production
of astatine-210 (T
1/2 = 8.1 h), which decays to polonium-210. It is purified from the bismuth target matrix by employing
liquid–liquid extraction using tributyl phosphate (TBP) in para-xylene from 7 M hydrochloric acid. Back extraction
of polonium-210 was performed by 9 M nitric acid. This method allows to purify a tracer amount of Po-210
(2.6 · 10
–13 mol) from macroscopic amount of Bi (2.8 · 10
–2 mol).
The solubility of 242PuO2 in the presence of aqueous Fe(II): the impact of precipitate preparation
Authors: Felmy Andrew R. , Moore Dean A. , Buck Edgar , Conradson Steven D. , Kukkadapu Ravi , Sweet Lucas , Abrecht David , Ilton Eugene S. 
Published: May 2014

Abstract
The solubility of different forms of precipitated 242PuO2(am) were examined in solutions containing aqueous Fe(II) over
a range of pH values. The first series of 242PuO2(am) suspensions were prepared from a 242Pu(IV) stock that
had been treated with thenoyltrifluoroacetone (TTA) to remove the 241Am originating from the decay of
241Pu. These 242PuO2(am) suspensions showed much higher solubilities at the same pH value and Fe(II)
concentration than previous studies using 239PuO2(am). X-ray absorption fine structure (XAFS) spectroscopy of the
precipitates showed a substantially reduced Pu–Pu backscatter over that previously observed in 239PuO2(am) precipitates,
indicating that the 242PuO2(am) precipitates purified using TTA lacked the long range order previously found
in239PuO2(am) precipitates. The Pu(IV) stock solution was subsequently repurified using an ion exchange resin and an
additional series of 242PuO2(am) precipitates prepared. These suspensions showed higher redox potentials and total
aqueous Pu concentrations than the TTA purified stock solution. The higher redox potential and aqueous Pu concentrations were in
general agreement with previous studies on 242PuO2(am) precipitates, presumably due to the removal of possible organic
compounds originally present in the TTA purified stock. 242PuO2(am) suspensions prepared with both stock solutions
showed almost identical solubilities in Fe(II) containing solutions even though the initial aqueous Pu concentrations before the
addition of Fe(II) were orders of magnitude different. By examining the solubility of 242PuO2(am) prepared from both
stocks in this way we have essentially approached equilibrium from both the undersaturated and oversaturated conditions. The final
aqueous Pu concentrations are predictable using a chemical equilibrium model which includes the formation of a nanometer sized Fe(III)
reaction product, identified in the 242PuO2(am) suspension both by use of 57Fe Mössbauer spectroscopy and
transmission electron microscopy (TEM) analysis.
Thermodynamic model for the solubility of BaSeO4(cr) in the aqueous Ba2+-SeO4
2−-Na+-H+-OH−-H2O system: Extending to high selenate concentrations
Authors: Rai Dhanpat , Felmy Andrew R. , Moore Dean A. , Kitamura Akira , Yoshikawa Hideki , Doi Reisuke , Yoshida Yasushi 
Published: May 2014

Abstract
The aqueous solubility of BaSeO4(cr) was studied at 23 ± 2 ℃ as a function of Na2SeO4
concentrations (0.0001 to 4.1 mol kg
–1) and equilibration periods (3 to 596 d). The equilibrium, approached
from both the under- and over-saturation directions, in this system was reached rather rapidly (≤3 d). The SIT and
Pitzer's ion-interaction models were used to interpret these data and the predictions based on both of these models agreed closely with
the experimental data. Thermodynamic analyses of the data show that BaSeO4(cr) is the solubility-controlling phase for
Na2SeO4 concentrations <0.59 mol kg
–1. The log 10
K
0 value for the BaSeO4(cr)
solubility product (BaSeO4(cr) ⇌ Ba2++ SeO4
2–
) calculated by the SIT and Pitzer
models were very similar (− 7.32 ± 0.07 with Pitzer and − 7.25 ± 0.11 with SIT). Although the BaSeO4(cr) solubility product
and Ba concentrations as a function of Na2SeO4 concentrations predicted by both the SIT and Pitzer models are similar, the
models required different sets of fitting parameters. For examples, 1) interpretations using the SIT model required the inclusion of
Ba(SeO4)2
2–
species with log 10
K
0 = 3.44 ± 0.12 for the reaction (Ba2++ 2SeO4
2–
⇌ Ba(SeO4)2
2–
), whereas these species are not needed for Pitzer model, and 2) at
Na2SeO4 concentrations >0.59 mol kg
–1 it was also possible to calculate the value for log 10
K
0
for the solubility product of a proposed double salt (Na2Ba(SeO4)2(s) ⇌ 2Na++ Ba2++ 2SeO4
2–
) which for the SIT model is − (8.70 ± 0.29) whereas for the Pitzer model it is
− (9.19 ± 0.19). The ion-interaction/ion-association parameters hitherto unavailable for both the SIT and Pitzer models required to
fit these extensive data extending to as high ionic strengths as 12.3 mol kg
–1 were determined. The model developed in
this study is consistent with all of the reliable literature data, which was also used to extend the model to barium concentrations as
high as 0.22 mol kg
–1 and pH ranging from 1.4 to 13.8, in addition to selenium concentrations as high as
4.1 mol kg
–1.
The use of composite ferrocyanide materials for
treatment of high salinity liquid radioactive wastes rich in
cesium isotopes
Authors: Toropov Andrey S. , Satayeva Aliya R. , Mikhalovsky Sergey , Cundy Andrew B. 
Published: May 2014

Abstract
The use of composite materials based on metal ferrocyanides combined with natural mineral sorbents for treatment of high salinity Cs-containing liquid radioactive waste (LRW) was investigated. The study indicated that among the investigated composites, the best sorption characteristics for Cs were shown by materials based on copper ferrocyanide. Several factors affecting the removal of cesium from LRW, namely total salt content, pH and organic matter content, were also investigated. High concentrations of complexing organic matter significantly reduced the sorption capacity of ferrocyanide sorbents.

Published: May 2014

Abstract
In this paper, an attempt to explore the use of laser induced breakdown spectroscopy (LIBS) technique for determination of
uranium in the vitrified simulated high level barium borosilicate waste glass matrix was made with a commercial portable LIBS
system. The emission spectrum of the waste glass being very complex, detailed study was done for proper choice of the emission
lines. Investigations were carried out to optimize the experimental parameters like laser energy and acquisition delay time for
the analysis. Calibration curves were obtained for two emission lines of U in these glasses. Effect of Ar atmosphere
was also studied and the signal intensity was found to be ∼5 times higher than in air atmosphere The emission lines used
for normalization with vast difference in the upper energy level compared to the line of interest were found to give poor
precision in air. In the Ar atmosphere, this effect was found to be much less significant and such emission lines can be used
as an internal standard to achieve precise calibration curves. LIBS approach will be useful for real time determination of U in
such samples, eliminating quantitative dissolution step required in many other analytical techniques like solution based
ICP-MS/OES.
Bargaining with Asymmetric Dispute Costs
Authors: Pecorino Paul , Van Boening Mark 
Published: May 2014

AbstractWe conduct a bargaining experiment in a stylized litigation setting. In the baseline, dispute costs are divided equally between the two parties. There are two treatments with an asymmetric distribution of dispute costs. The design allows us to gain insight into how a fair offer evolves with the distribution of dispute costs. The amount of surplus in the average offer depends on the total amount of surplus available and not on the distribution of dispute costs. About 28% of the total surplus is contained in the average offer, regardless of the distribution of dispute costs. Based on the empirical rejection frequencies, we calculate that the optimal offer contains 13% of the total surplus from settlement. We also find evidence that disputes are more likely when dispute costs are asymmetrically distributed. This suggests that the experimental subjects have more difficulty coordinating on a fair offer when dispute costs are not symmetric.
Automated fault detection using deep belief
networks for the quality inspection of
electromotors
Authors: Sun Jianwen , Wyss Reto , Steinecker Alexander , Glocker Philipp 
Published: May 2014

Abstract
Vibration inspection of
electro-mechanical components and systems is an
important tool for automated reliable online as well as
post-process production quality
assurance. Considering that bad electromotor samples are
very rare in the production line, we propose a novel
automated fault detection method named “Tilear”, based on
Deep Belief Networks (DBNs) training only with good electromotor
samples. Tilear consctructs an
auto-encoder with DBNs, aiming to
reconstruct the inputs as closely as possible. Tilear is
structured in two parts: training and
decision-making. During
training, Tilear is trained only with informative features
extracted from preprocessed vibration signals of good
electromotors, which enables the trained Tilear only to know
how to reconstruct good electromotor vibration signal
features. In the decision-making
part, comparing the recorded signal from test
electromotor and the Tilear reconstructed signal, allows to
measure how well a recording from a test electromotor matches the Tilear model
learned from good electromotors. A reliable decision can
be made.
Effect of Rotation on Flow Field and Film Cooling Effectiveness in Film-Cooled Turbine Rotors
Authors: Zhu Xiaocheng , Liu Liangliang , Yuan Feng 
Published: May 2014

AbstractExperimental and numerical investigations of flow field in a film-cooled turbine model under stationary and rotating conditions in a low-speed wind tunnel are conducted. The effects of different blowing ratios (M = 1.5, 2) on the flow field are studied. Results revealed a secondary flow near the blade surface in the wake region behind the jet hole. Compared with the stationary turbine, there exists centrifugal force and Coriolis force in the flow field of the rotating turbine, and these forces cause changes in the flow field in the rotating turbine. The effect of rotation on the flow field and film cooling effectiveness in the Y-Z planes on the pressure side is stronger than on the suction side, and results in lower film cooling effectiveness on the pressure surface of the rotating turbine blade compared with the stationary turbine. As the blowing ratio increases, the secondary flow in the wake region will become stronger, thereby enlarging the range of the wake.
The Future in the Post: Utopia and the Fiction of the New South Africa
Authors: Green Michael 
Published: May 2014

Abstract
Post-apartheid South Africa, having recently come into its own in terms of the Utopian national vision that has driven and informed its history, is in danger of assuming this to be the end of its history, with only a better delivery of that static vision being in question. This paper considers the utopian as a vital element in oppositional and revolutionary strategies. It then looks at the important role the future, deployed in a utopian mode, took on in anti-apartheid texts during the darkest period of the liberation struggle, and asks if we can identify a similar impulse in texts that take as their subject some of the less satisfactory aspects of the post-apartheid condition. Focusing on Phaswane Mpe’s Welcome to Our Hillbrow, one of the texts regularly presented as representative of new South African nation, the paper examines post apartheid fiction’s particular avoidance of a nationalised sense of the political. It then places this against the question of the national in relation to the utopian, and argues that the nation is useful to us as an idea if it is always beyond us, always calling the present into question.

Abstract
Pierre Bourdicu (1930-2002) is one of the most influential sociologists of our time. BUI although his notion of 'cultural capital' has become a household word. many literary scholars still shy av.'3Y from the sheer bulk of his writings. This essay offers a short introduction to his work. focusing on two crucial studies. Distinction: A Social
Critique of the Judgement of Taste and The Rules of Art: Genesis and Structure of the
Literary Field. In the first part. four key terms - capital. field. habitus and social space - are explained with reference to Bourdieu's empirical research in France and Algeria. The second part applies Bourdieu's theory to (I) the interpretation of literary texts. (2) problems of literary history. and (3) aspects of literary theory. It is the aim of this essay to suggest the wealth of Bourdieu's sociological insights - and to show that Bourdieu has an important role to play in literary and cultural studies.

spectra are assigned based on a comparison to previously reported
anharmonic and harmonic CCSD(T) vibrational frequencies and

vibrational frequencies a scaling factor of 0.9808 is determined,
resulting in comparable absolute deviations. The influence of the
D2-messenger molecules on the structure and the IRPD

matrix isolation studies additional, in particular weaker, IR-active
transitions are identified.
