Effects of ceramsite on methane and hydrogen sulphide productions from macroalgae biomass

The easy acidification and high hydrogen sulfide （H2S） production during anaerobic digestion of macroalgae limited its application in biomethane production. In order to investigate the effects of ceramsite on methane and HzS productions during anaerobic digestion of macroalgae, batch experiments ofMacrocystis pyrifera were carried out. Four groups named C0, C1, C2 and C3 added with 0, 1.5, 3.0 and 4.5 g/g substrate of ceramsite, respectively, were studied and compared. The highest cumulative methane yield of 286.3 mL/g substrate is obtained in C2, which is 40.11% higher than that of CO. The cumulative HzS yields of C1, C2 and C3 are 32.67%, 44.66% and 53.21% lower than that of CO, respectively. Results indicate that ceramsite addition permits higher methane yields, shorter lag-phase time and lower HzS yields during anaerobic digestion of Macrocystispyrifera.

THERMOLUMINESCENT AUTHENTICATION OF ANCIENT CHINESE POTTERY

A rapid and effective TL technique to authenticate ancient Chinese pottery is proposed in the paper. Twenty three samples, ranging in age from 200 to 9000 a,including multiple styles and shapes and drawn from diverse and remote areas in China have been used to establish the typical annual dose as 5.5mGy/a and its associated deviation. Ten unauthenticated samples are then appraised using the technique which,in nearly all cases, leads to satisfactory results.

Upconversion Luminescence of Er^3＋ and Co-Doped Er^3＋/Yb^3＋ Novel Transparent Oxyfluoride Glasses and Glass Ceramics： Spectral and Structural Properties

Transparent oxyfluoride silicate precursor glasses and glass ceramics with the novel composition （1） SiO2-PbO-PbFE-Er2O3, （2） SiO2-GeOE-PbO-PbFE-Er2O3 （3） SiO2-Al2O3-Y2O3-Na2O-NaF-LiF-Er2O3-YbF3 doped with Er^3＋ and co-doped with Er^3＋/Yb^3＋ ions were synthesized. X-ray diffraction analysis （XRD） and Er3＋ absorption spectra revealed precipitation of PbF2 nanocrystals dispersed in the glassy matrix. Under 980 nm laser excitation, intense green, red and near IR bands of upconversion luminescence （UCL） were recorded both before and after heat treatment. In the glass ceramics the upconversion intensity increased significantly. To our knowledge, for the first time the composition of the glass ceramics characterized by the small-angle neutron scattering （SANS） showed the cluster organization of PbF2 nanocrystals.

Educating Children in the Family Created in the Second Marriage in Today＇s Lithuania

Since the end of the twenty-first century, relationships in the family have been rapidly changing in Lithuania. The changes correspond to changes in the birth-rate. The former model of birth-rate which was characterized by the prevalence of legitimate children, child-bearing at a younger age and which ensured a change of generations, it was replaced by a new model characterized by having illegitimate children, the postponement of child-bearing, and low birth-rate, which does not ensure a change of generations. Although love relationships, marriage, and children are still considered to be the recognized values, these changes have affected the conception of child＇s education in the family and the perception of child as a value. It is therefore relevant to evaluate future spouses＇ preparation for a modern marriage and to constantly improve it. Such preparation is usually understood as young people＇s readiness far their first marriage. Readiness for the second marriage and child＇s education in the second family are no less important though still insufficiently explored empirically and theoretically generalized. This paper explores attitudes to child＇s education in the second marriage. The research was conducted inquiring people who wanted to create a family or establish long-term relationships. They were members of the online dating site ＂Harmonious Couple＂.

The Artistic Styles of Ceramic Censers in Song Dynasty

Song Dynasty was very significant in Chinese feudal history, and ceramic industry boomed during that time： all kinds of kilns were scattered all over the country, and ceramic art achieved great success. Among those achievements, ceramic censers were a very typical one which features unique styles in patterns, decorations, and glaze colors. This paper covers the developing process and artistic characteristics of censers in Song Dynasty.

Controllable precipitation and photoluminescence of efficient green-emitting crystalline phase from luminescent CaO-SiO_2 glass-ceramic system

A new kind of glass-ceramic phosphor, which contains crystalline phases with green emissions, is explored. The glassceramic is prepared through semi-melt-quenching procedure with a nominal composition of （Ca0.99Eu0.01）3Si2O7. The greenemitting crystals are precipitated and identified to be β-Ca2SiO4： Eu2＋ which is responsible for 510 nm-peaked much broader band emissions holding at 1550 ℃ for half an hour. In terms of the available light scattering theory, the appearance of opaque is discussed by closely associating with size and morphology of luminous β-Ca2SiO4 crystalline phase in glass.

Effect of arc-current and spray distance on elastic modulus and fracture toughness of plasma-sprayed chromium oxide coatings

In this experimental study, chromium oxide powder was sprayed on a low-carbon steel substrate using the atmospheric plasma spray process. The current and standoff distances(SODs) were varied to study their effect on the fracture toughness of the coatings. Theoretically, as the arc current increases, the melting of the ceramic oxide should increase and this in turn should lead to the formation of a dense coating. However,it was observed that if the arc power is too high and because the particle size of the powder is small(approximately 30 μm), the particles tend to fly away from the plasma core. Similarly, an appropriate SOD should provide the particles with more melting time, thus resulting in a dense coating. On the other hand, a larger SOD leads to the solidification of the molten particles before the droplets can reach the substrate. All these effects may lead to substantial variation in the fracture toughness of the coating. The present paper attempts to correlate the plasma spraying parameters and microstructure of the coating with the fracture toughness and other primary coating properties.

Composite Eshelby model and domain band geometries of ferroelectric ceramics

A method of composite Eshelby inclusion is proposed for aferroelectric grain with domain switching embedded in a polycrystalline ferroelectric matrix. The method quantifies the twinning structure due to spontaneous polarization, as well as the conventional and non-conventional domain structures after poling induced domain reorientation of 90 degree. The predicted parameters include the volume fraction, the thickness, and the surface inclination angle of switched domain plates. The domain wall energy for non-conventional domain structures is derived in terms of the arrays of misfit dislocations. The domain geometries predicted by the present work agree with the measured domain morphology near an indentation crack tip when subjected to lateral electric field.

Concentration quenching in transparent glass ceramics containing Er^(3+):NaYF_4 nanocrystals

In this work, we have studied the concentration quenching in transparent glass ceramics containing Er^3＋：NaYF4 nanocrystals. For different concentrations, the emission spectra and decay curves of the ^4I/3/2 → ^4I15/2 emission were measured. The Er-concentration dependence of integrated intensity and lifetime of ^4I13/2→^4I15/2 emission are showed. With the increase of the Er^3＋ doping concentration, the 1.5 μm fluorescence emission first increases, then decreases, and the lifetime falls gradually. With 980 nm excitation, the efficiency of the energy transfer from Er^3＋ to quenching centers reaches 73.73% for the sample with 4 mol% Er^3＋. Meanwhile, owing to the relation of fluorescence integrated intensity and Er-concentration, a dipole-dipole quenching mechanism in the framework of a limited diffusion regime has been proved. Using the limited diffusion case, the critical concentration for quenching has been determined from a fitting equation of the lifetime and Er-concentration. The fit- ting result shows the critical concentration for quenching is higher than the values obtained in Er-doped different glass by an order of magnitude.

Brittle-Ductile Transition of Ferroelectric Ceramics Induced by Thermally Activated Dislocation Emission

Thermally activated dislocation emission in high-temperature ferroelectric ceramics is investigated through an assumption of thermal stability and a novel analytical method. The stress intensity factor (SIF) arising from domain switching is evaluated by using a Green's function method, and the critical applied electric field intensity factor (CAEFIF) for brittle fracture at room temperature is obtained. Besides, the lowest temperature for single dislocation emission before brittle fracture is also obtained by constructing an energy balance. The multi-scale analysis of facture toughness of the ferroelectric ceramics at high temperature is carried out. Through the analysis, the CAEFIF for crack extension is recalculated. The results show that the competition and interaction effects between dislocation emission and brittle fracture are very obvious. Besides, the higher critical activation temperature, the more columns of obstacles will be overcome. Additionally, the shielding effect arising from thermally activated dislocations is remarkable, thus, the brittle-ductile transition can promote the fracture toughness of high-temperature ferroelectric ceramics.

Populism and Political Party Institutionalisation in the Three Baltic States of Estonia, Latvia and Lithuania

The three Baltic states of Estonia, Latvia and Lithuania make for interesting comparative case studies in the rise of contemporary populism in Europe. All three countries share a similar modem history, democratic political system, level of economic development and are in the same western-oriented regional clubs （NATO, European Union, OSCE, European Council and, in the case of Estonia and Latvia, OECD, etc.）. However, they do differ in the extent to which populism has played a role in their national politics. Populism has played a marginal role in Estonian politics, but has long been central to the Latvian party system and influential in Lithuanian politics. This article tackles two key issues in the study of populism. First, it focuses on political party institutionalisation as the key variable in explaining the differing impact of populist political parties across the Baltic states. It examines and explains the higher turnover of political party creation and destruction in Latvia and, to a lesser extent, Lithuania and argues that institutions--and par- ticularly the laws that frame party organisations and participation in elections-- create political opportunities for populist parties. The second part of the paper considers the different types of populist parties to have emerged in the Baltic states in recent decades. While previous studies of populism in the Baltic states （such as Auers and Kasekamp in J Contemp Eur Stud 17（2）：241-254, 2009; Auers and Kasekamp, in： Wodak et al （eds） Right wing populism across/beyond Europe, Bloomsbury Academic Press, London 2013） have explicitly focused on Radical Right Populist parties, this article additionally identifies a number of parties in the region that are not explicitly radical right, but are certainly populist.
