Synthesis of mono- and bis-1,2,3-triazole derivatives containing 4H-pyran-4-one moiety by 1,3-dipolar cycloaddition reaction
Authors: Saraei Mahnaz , Hossienzadeh Roshanak , Jabbari Maryam 
Published: March 2015

Abstract
An efficient and green methodology for the synthesis of 1,2,3-triazoles substituted with a 4H-pyran-4-one moiety was developed by treatment of 2-(4-azidomethylphenyl)-6-phenyl-4H-pyran-4-one with alkynes in water. The yields are good to excellent. The reactions of the terminal alkynes occur in the presence of Cu(I) as catalyst and lead to the formation of 1,4-disubstituted 1,2,3-triazoles. Also, bis-1,2,3-triazoles containing 4H-pyran-4-one moiety were synthesized by the reaction of 2,6-bis[4-(azidomethyl)phenyl]-4H-pyran-4-one with internal alkynes in 51–84% yields.
Modeling and Improving the Performance of Cabinet Solar Dryer Using Computational Fluid Dynamics
Authors: Ghaffari Ali , Mehdipour Ramin 
Published: March 2015

Abstract
In this study, a new approach for numerically modeling of an entire cabinet solar dryer is proposed. Collector, drying chamber and chimney are the three principle sections considered in the present modeling. The collector section containing a cover and an absorber plate is modeled applying energy and fluid flow equations to obtain temperature distribution inside the collector. Due to the non-linear behavior of the governing equations as well as variety of effective variables, an iterative method is employed for solution. Regarding the geometry complexity of the drying chamber along with the air compressibility (that in turn causes coupling of momentum and energy equations) drying chamber is simulated by CFD method. Chimney’s effect and effective parameters in suction are comprehensively considered in the present model. The numerical results are in line with experimental results which show that the model can be applied with certainty to employ the dryer for drying highly demanded and time-consuming products in a scientific, sanitary, and timely manner. The model is then optimized by adding some baffles to achieve higher efficiencies and accelerate the drying process.
Luminescence Properties of the Thermographic Phosphors Dy3+:YAG and Tm3+:YAG for the Application in High Temperature Systems
Authors: Jovicic Gordana , Zigan Lars , Will Stefan , Leipertz Alfred 
Published: March 2015

Abstract
The high temperature sensitivity of the luminescence emission of
thermographic phosphor (TP) particles favours its utilization for the
measurement of wall or gas temperatures in combustion devices. The
present work focuses on the luminescence behavior and suitability of
two lanthanide ion types (Tm and Dy) doped in a YAG host
crystal for high temperature applications. The Dy:YAG is
a well-known thermographic phosphor and is used here as a reference for
the comparison with Tm:YAG TP. Additionally its dopant
concentration is varied to improve its signal intensity for high
temperature applications. For the studied thermographic phosphors
phosphorescence spectra, intensity ratios and luminescence decay time
are characterized for a wide temperature range up to
1573 K.
The SMC′ Is a Highly Accurate Approximation to the Ancestral Recombination Graph
Authors: Wilton Peter R , Carmi Shai , Hobolth Asger 
Published: March 2015

Abstract
Two sequentially Markov coalescent models (SMC and SMC′) are available as tractable approximations to the ancestral recombination graph (ARG). We present a Markov process describing coalescence at two fixed points along a pair of sequences evolving under the SMC′. Using our Markov process, we derive a number of new quantities related to the pairwise SMC′, thereby analytically quantifying for the first time the similarity between the SMC′ and the ARG. We use our process to show that the joint distribution of pairwise coalescence times at recombination sites under the SMC′ is the same as it is marginally under the ARG, which demonstrates that the SMC′ is, in a particular well-defined, intuitive sense, the most appropriate first-order sequentially Markov approximation to the ARG. Finally, we use these results to show that population size estimates under the pairwise SMC are asymptotically biased, while under the pairwise SMC′ they are approximately asymptotically unbiased.
The Aggregation-Prone Intracellular Serpin SRP-2 Fails to Transit the ER inCaenorhabditis elegans
Authors: Silverman Richard M , Cummings Erin E , O’Reilly Linda P , Miedel Mark T , Silverman Gary A , Luke Cliff J , Perlmutter David H , Pak Stephen C 
Published: March 2015

AbstractFamilial encephalopathy with neuroserpin inclusions bodies (FENIB) is a serpinopathy that induces a rare form of presenile dementia. Neuroserpin contains a classical signal peptide and like all extracellular serine proteinase inhibitors (serpins) is secreted via the endoplasmic reticulum (ER)–Golgi pathway. The disease phenotype is due to gain-of-function missense mutations that cause neuroserpin to misfold and aggregate within the ER. In a previous study, nematodes expressing a homologous mutation in the endogenous Caenorhabditis elegans serpin, srp-2, were reported to model the ER proteotoxicity induced by an allele of mutant neuroserpin. Our results suggest that SRP-2 lacks a classical N-terminal signal peptide and is a member of the intracellular serpin family. Using confocal imaging and an ER colocalization marker, we confirmed that GFP-tagged wild-type SRP-2 localized to the cytosol and not the ER. Similarly, the aggregation-prone SRP-2 mutant formed intracellular inclusions that localized to the cytosol. Interestingly, wild-type SRP-2, targeted to the ER by fusion to a cleavable N-terminal signal peptide, failed to be secreted and accumulated within the ER lumen. This ER retention phenotype is typical of other obligate intracellular serpins forced to translocate across the ER membrane. Neuroserpin is a secreted protein that inhibits trypsin-like proteinase. SRP-2 is a cytosolic serpin that inhibits lysosomal cysteine peptidases. We concluded that SRP-2 is neither an ortholog nor a functional homolog of neuroserpin. Furthermore, animals expressing an aggregation-prone mutation in SRP-2 do not model the ER proteotoxicity associated with FENIB.
Immobilization of Persimmon Tannin on Cellulose Viscopearls and Removal of Caffeine from Aqueous Solution
Authors: Alejandra Murguía Flores Dennise , La Ode Ahmad , Kunimoto Ko-Ki , Ríos Jaime Bonilla 
Published: March 2015

ABSTRACTAn eco-friendly adsorbent was prepared by immobilization of Persimmon Tannin (PT) in cellulose viscopearls to remove caffeine. The immobilization time within a range of 1-42days was performed. Batch adsorption experiments were studied for different Persimmon Tannin on Cellulose Viscopearls (PTIC) gel samples, adsorbent dosage, and initial caffeine concentration. FTIR indicated that PT was successfully immobilized onto viscopearls. SEM images showed differences especially on particle size and shape, between control, day7, and day28 of PTIC gel samples. The adsorption capacity results showed that removal of caffeine as the amount of adsorbed increased, the percentage of caffeine adsorption increased accordingly, but it decreased with the increased in initial caffeine concentration. Results for different PTIC gel samples showed that day 42 PTIC sample exhibits the highest adsorption capacity of caffeine solution of 43.3mg/g. The samples showed water contents in the range of 343-324%.The equilibrium data were analyzed using Freundlich and Langmuir equations. It suggested that viscopearls acted to be a suitable insoluble matrix to immobilized PT, instead of using crosslinkers.

Published: March 2015

ABSTRACTRare earth (e.g., Eu, Er, Yb, Tm) doped Y2O3nanocrystals are promising fluorescent bioimaging agents which can overcome well known problems of currently used organic dyes like photobleaching, phototoxicity, and light scattering. Furthermore, the alternative quantum dots (QDs) composed of heavy metals (e.g., CdSe) possess inherently low biocompatibility due to the heavy metal content. In the present work, monodisperse spherical Y2O3:Eu3+nanocrystals were successfully synthesized by microwave assisted urea precipitation method followed by thermochemical treatment. This is a green, fast and reproducible synthesis method, which is surfactant and hazardous precursors free. The as prepared particles were non-aggregated, spherical particles with a narrow size distribution. The calcined particles have a polycrystalline structure preserving the monodispersity and the spherical morphology of the as prepared particles. After calcination of Y(OH)CO3:Eu3+precursors at 900°C for 2 hours, a highly crystalline cubic Y2O3structure was obtained. The Y2O3:Eu3+spherical particles showed a strong red emission peak at 613nm due to the5D0–7F2forced electric dipole transition of Eu3+ions under UV excitation (235 nm) as revealed by the photoluminescence analysis (PL). The effect of reaction time on size and photoluminescence properties of calcined particles and also the effect of reaction temperature and pressure on the size and the yield of the precipitation process have been studied. The intense red fluorescent emission, excellent stability and potential low toxicity make these QDs promising for applications in bio-related areas such as fluorescence cell imaging or fluorescence bio labels.
Oxygen Vacancies at the γ-Al2O3/STO Heterointerface Grown by Atomic Layer Deposition

Published: March 2015

ABSTRACTWe report the epitaxial growth of γ-Al2O3 on SrTiO3 (STO) substrates by atomic layer deposition (ALD). The ALD growth of γ-Al2O3 on STO(001) single crystal substrates was performed at a temperature of 345 °C. Trimethylaluminum and water were used as co-reactants. In-situ reflection high-energy electron diffraction and ex-situ x-ray diffraction were used to determine the crystallinity of the Al2O3 films. In-situ x-ray photoelectron spectroscopy was used to characterize the Al2O3/STO heterointerface. The formation of a Ti3+ feature is observed in the Ti 2p spectrum of STO after the first few ALD cycles of Al2O3 and even after exposure of the STO substrate to trimethylaluminum alone at 345 °C. The presence of a Ti3+ feature is a direct indication of oxygen vacancies at the Al2O3/STO heterointerface, which provide the carriers for the quasi-two dimensional electron gas at the interface.
A Rapid Solar Reduction Method to TiO2/MoO2/Graphene Nanocomposites for Photocatalytic Water Splitting
Authors: Aravind.S.S Jyothirmayee , Ramanujachary Kandalam , Vaden Timothy D. , Mugweru Amos 
Published: March 2015

ABSTRACTSemiconductor photocatalysis has emerged as an interesting area of research since the discovery of Honda-Fujishima effect. In this study, TiO2/MoO2/graphene composites have been prepared by a solar radiation-assisted co-reduction method, wherein ammonium tetrathiomolybdate salt and graphite oxide are reduced to MoO2 and graphene respectively along with TiO2. The method involved the utilization of focused pulses of natural sunlight using a simple convex lens, thereby eliminating the need for harmful reducing agents. The compound was characterized by XRD and SEM for phase identification and morphology. The TiO2/MoO2/graphene composite exhibits superior photocatalytic water splitting activity without using a co-catalyst. In addition, we demonstrate the electrocatalytic hydrogen production using this earth abundant catalyst, which shows high current density (60 mA/cm2) and low Tafel slope (47 mV/dec). The hydrogen evolved during photocatalysis was detected by gas chromatography.
Selective Ordering of Pertechnetate at the Interface between Amorphous Silica and Water: a Poisson Boltzmann Treatment
Authors: Williams Christopher D. , Travis Karl P. , Harding John H. , Burton Neil A. 
Published: March 2015

ABSTRACTCalculations based on Poisson-Boltzmann theory are used to investigate the equilibrium properties of an electrolyte containing TcO4−and SO42−ions near the surface of amorphous silica. The calculations show that the concentration of TcO4−is greater than SO42−at distances less than 1 nm from the surface due to the negative charge density caused by deprotonation of the amorphous silica silanol groups. At lower pH, the surface becomes protonated and the magnitude of this effect is reduced. These results have implications for the potential use of oxyanion-SAMMS for the environmental remediation of water contaminated with99Tc.

Contested Meanings: Earth Religion Practitioners and the Everyday
Authors: Blain Jenny 
Published: March 2015

In many ‘traditional’ cultures, religion and magic
are not easily separated from people’s everyday
existence. Today, an increasing number of people
within North America are drawn to some form of
earth-centred spirituality, whether as solitary
practitioners or members of Neopagan circles,
Wicca covens, Heathen kindreds or Druid groves.
For many of these people, religion and spirituality
do not form a closed category of their experience:
they inform, and are formed by, events of their
lives as distinct or diverse as childbirth, gardening, social protest, sexual expression, and everyday
occupations of work and leisure

Birds Hill Park, the Dakota Eagle Sundance, and the Sweatlodge: Establishing a Sacred Site in a Provincial Park
Authors: Ruml Mark 
Published: March 2015

Little scholarly analysis has been made of the processes involved in returning
Indigenous sacred locales to contemporary religious usage. In this paper, a historical and descriptive sketch is provided of the institutional and personal
systems in place in the recovery of a Dakota sundance site in Birds Hill Provincial Park. After several meetings with various officials from the Manitoba Department of Conservation the White Buffalo Spiritual Society was given permission to hold a sundance ceremony at Birds Hill Provincial Park, located approximately twenty kilometers north of the City of Winnipeg,
Manitoba, Canada. From 2000 until 2007 an annual sundance and regular sweatlodge ceremonies were held at a site in the Park selected by members of the White Buffalo Spiritual Society in consultation with Conservation officials. This article outlines significant events in the process of establishing and maintaining a sacred space in a Provincial Park, introduces
the reader to the Dakota Eagle sundance, and notes the reasons why the sundance and sweatlodge ceremonies are viewed as important for the individual and community well-being.
Etty Hillesum: Love Calls for Spiritual Discernment
Authors: Pleshoyano Alexandra Ileana 
Published: March 2015

Etty Hillesum, a young Jewish woman living in Amsterdam, died on
November 30th 1943 in Auschwitz when she was twenty-nine years old, leaving behind a diary (eleven exercise books) and seventy-eight letters which have drawn responses across the world in the form of books, reviews, articles, documentaries, plays and visual art. By adding this essay to the body of literature on Hillesum’s writings, I hope to change the process of recuperation so that her texts may be read differently. What I hope to contribute
is a pluralist and universal’s perspective on the comprehension of love in Hillesum’s writings. This subject has not as yet been given enough thought and attention. And yet, when one tries to understand Hillesum’s spiritual path it is mandatory to interpret what she understood by the so common word of “love.” Hillesum’s writings do indeed articulate a remarkable
experience of God in times when many just abandoned a faith that seemed so useless.

11. O MITO DA CAVERNA PROJETADO NO ADMIRÁVEL MUNDO NOVO: A ESCRAVIDÃO TECNOLÓGICA
Authors: CONCEIÇÃO Celso Augusto Nunes da , FERREIRA Valdnei Martins 
Published: March 2015

<p>O Mito da Caverna , de Platão, foi escrito no século IV a.C. com a finalidade de evidenciar a forma como o povo é escravizado sem que perceba o que realmente está acontecendo, mas acenando para libertação. Com uma roupagem evolutiva, Aldous Huxley escreveu, no séc. XX, a obra Admirável Mundo Novo, desenvolvendo o caráter futurista pelo benefício que o avanço científico provoca no povo, condicionando-o a contemplar as suas admiráveis maravilhas. O cotejamento entre essas duas obras propicia a projeção da parábola da caverna no processo tecnológico mais amplo, em que o propósito do controle da estabilidade social pelos governantes é atingido. Aplicado aos dias de hoje, o mercado cria necessidades atrativas na população, sendo grande parte delas as famosas mídias: celulares, tablets, internet, redes sociais, etc. O resultado é devastador em termos de educação porque o uso do condicionamento evita que o indivíduo acesse os livros e com isso possa refletir sobre as informações neles contidas, ou seja, é a escravidão tecnológica de forma subliminar.</p>

<p> A Revista Diálogos do Direito chega a seu sétimo número, agora pleiteando construir um diálogo entre professores, alunos, comunidade acadêmica, interna e externa, com a obra de Leon Tolstói, “A morte de Ivan Ilitch”. Sem dúvida, a edição contou com o entusiasmo com que a obra também foi discutida nos corredores, bar, restaurante, biblioteca, trabalhos, provas, e todo tipo de atividade acadêmica em que se poderia – de uma forma ou de outra – revelar e realizar comparações da vida que se tem, com a vida do personagem Ivan Ilitch, construído por Leon Tolstoi.</p><p> Há, portanto, uma transmutação, e não obstante a distância histórica da origem da obra foi realizada com tranquilidade, talvez dado ao fato de que convivemos na atualidade com uma melancolia e uma luta permanente pelo sentido da vida, que certamente transborda os limites da vida do personagem de Tolstoi, para atingir a todos.</p><p> O melhor do diálogo pode ser sempre aquele dos corredores, mas sempre respingos do debate transparecem nas mais diversas formas pelas quais cada professor ou colaborador/autor acaba expressando a forma como percebe a obra, e o contexto no qual deseja inseri-la, a fim de explorar ainda mais suas qualidades literárias. E isso hoje em dia acaba se refletindo inclusive nas conversas pelas mídias, pelos grupos, pelas formas contemporâneas e muitas vezes mais imediatas de referenciar, comentar e relacionar que a tecnologia nos proporciona – o que só enriquece ainda mais o debate!</p>
