S.T.R.I.D.E. Professional Guide to Compression Garment Selection for the Lower Extremity
Authors: Bjork Robyn , Ehmann Suzie 
Published: June 2019

The following supplement is a rare example of a paper that combines clinical experience and theoretical knowledge on textiles used in compression therapy. The authors' intention is to propose a decision support system for choosing specific compression devices, which can be adjusted to counteract the individual signs and symptoms in an optimally adopted way. The document concentrates on compression devices which can be self-applied by the patients—compression stockings and adjustable wraps. The acronym ‘S.T.R.I.D.E.’, incorporating both textile characteristics and clinical presentation, stands for: Shape, Texture, Refill, Issues, Dosage and Etiology. The intent of the mnemotechnical value is to highlight that successful compression includes more than dosage alone. In addition to dosage, etiology and patient presentation need to be incorporated, including a patient's physical ability to use compression effectively as part of the daily routine, thereby promoting adherence. The suggested algorithms provide a valuable guide to stride across the important, but still underestimated field of medical compression therapy and will help to put the prescription of a specific product on a more rational basis.

En este artículo abordamos dispositivos que los feminismos –como herramientas reflexivas y de acción- sirven para conmover y contribuyen a que la educación sea un motor de . Tratamos su contribución a la construcción de una educación que recupere y se consolide desde las diferencias, la inclusión, el reconocimiento y la solidaridad, la libertad.
Los aportes feministas nos llevan a concebir una pedagogía que ayude a interrogarse, a dudar, a preguntar (nos), a co-crear y construir, en donde se escuchen los silencios y se nos habilite a reír. Proponemos como herramientas nodales el diálogo -como mecanismo de transformación-, el construccionismo, la interculturalidad y las narrativas como perspectivas que permiten hacer de nuestras prácticas, practicas fundadas, reflexivas y situadas. Presentamos el Colectivo de Mujeres del Chaco como un caso explícito de territorio cooperativo de construcción de saberes compartidos.
El feminismo en las universidades
Authors: Bartra Eli 
Published: June 2019

Este artículo intenta pensar críticamente las categorías género y mujer en el marco del pensamiento feminista. El uso indiscriminado del concepto “género” ha terminado convirtiéndose en una aberración que, además, no presenta ningún riesgo para los quehaceres tradicionales
androcéntricos de las disciplinas. Asimismo, plantea críticamente los retos y desafíos que se presentan para poder hablar de “feminismos” en la academia y en la ciencia latinoamericana. La autonomía tanto de la educación superior como del feminismo deben sostenerse en este nuevo milenio que aún no hace espacio al feminismo en sus currículas.

Dil: The Crying Game, espectatoralidade e agenciamento trans em Traídos pelo Desejo
Authors: Spitzner Marcelo 
Published: June 2019

Este artigo, através de uma perspectiva transfeminista e queer, discute um recorte do filme Traídos pelo Desejo, como pertence a um campo que convencionalmente tem-se chamado de Trans Cinema. Através da discussão do filme busca-se, além de problematizar o conceito de gaze, a partir de um viés binário, propor uma espectatoralidade agencial da personagem trans. Essa espectatoralidade e agenciamento da personagem Dil são possíveis através de um momento, que pode ser observado em vários filmes do Trans Cinema, em que o personagem experimenta uma ruptura com o sentimento de medo ou da exposição a potencial violência, é um momento de intenso engajamento fílmico que permite uma fuga temporária do domínio cinematográfico dos efeitos negativos de cenas constrangedoras. A esse momento poderíamos chamar de “ válvula de escape” e pode estar associado a diversos elementos, tais como sonho, fantasia, dança, etc. Nesse filme, associo-o a performance da música (ou músicaescape) The Crying Game.Palavras-chave: Trans Cinema; Espectatoralidade; Gaze; Agenciamento; Teoria queer.

Authors: Cover Maciel , Rodrigues Patrícia Silveira 
Published: June 2019

No contexto em que o Brasil se torna o principal consumidor mundial de agrotóxicos, um conjunto de atores sociais como movimentos sociais do campo, organizações não governamentais, sindicatosrurais e urbanos, organizam a “Campanha Permanente contra os Agrotóxicos e pela Vida” com o intuito de chamar a atenção para a sociedade brasileira diante do eminente risco que estes produtos químicos acarretam para a saúde humana e para o meio ambiente. Por meio desse artigo propomos refletir sobre o processo desenvolvido por esta campanha a partir da seguinte questão: que fatores podem ser mobilizados para explicar o crescimento em termos organizativos da Campanha Permanente contra os Agrotóxicos e pela Vida? O artigo é fundamento na análise de materiais produzidos pela campanha, bem como pelas adesões de novos atores sociais que adentraram na campanha desde seu começo. Em termos teóricos, buscamos nos fundamentar nas discussões sobre sociedade global de risco de Ulrich Beck bem como no conceito de sistemas peritos de Anthony Giddens.Palavras-Chaves: Agrotóxicos; Movimentos Sociais do Campo; Sociedade Global de Risco; Sistemas Peritos.

Published: June 2019

ABSTRACTWe demonstrate the three-dimensional arrangement of silica microparticles in body-centered cubic lattice structure using both a relief pattern formed in the film of the azopolymer and silica micro particles dispersed in a nematic liquid crystal. In the method, firstly, the square lattice relief structures with the spacing of 2000 nm and the depth of 400 nm were formed on the azopolymer film by twice exposure to two beam interference patterns with coherent light of 488 nm in wavelength from Ar ion laser. Next, a nematic liquid crystal (5CB) containing 2000 nm diam. silica microparticles, with the surface modified with silane coupling reagent giving rise to homeotropic texture, was dropped on the relief structure on the azopolymer. The two dimensional square lattice structures of the micropaticles were formed spontaneously in an isotropic to nematic phase transition. Finally, the microparticles were three-dimensionally arranged by using optical tweezers. The microparticles were successfully stacked in a four-step pyramid structure with body centered tetragonal lattice structure.

Published: June 2019

ABSTRACTSelf-assembled monolayers (SAMs) of decanoic acids were prepared on cerium oxide nanoparticles (NPs). The dispersion of the NPs was improved by increasing the packing density of decanoic acid SAM on the NPs. Highly concentrated ceria nanofluids more than 22 vol% (about 77 wt%) in cyclohexane and trans-decalin were achieved, according to the criterion to the packing density and chain length of the alkanoic acid of the SAM to disperse the ceria NPs in nonpolar organic solvents proposed previously. Temperature effect on the dispersion was also examined and it was turned out that the dispersion was strongly enhanced with activation of Brownian motion.
Enhanced photocurrent due to interband transitions from InAs quantum dots embedded in InGaAs quantum well solar cells
Authors: Vasan R. , Makableh Y. F. M. , Sarker J. C. , Manasreh M. O. 
Published: June 2019

ABSTRACTSolar cells based on InAs quantum dots embedded in InxGa1-xAs quantum wells grown on n-type GaAs substrate were fabricated and tested. Solar cells with In mole fraction (x) in the range of 0-40% were investigated. The performance of the solar cells was evaluated using current-voltage characteristics, spectral response, and quantum efficiency measurements. The spectral response and quantum efficiency spectra possess several peaks along the lower energy side of the spectra, which are attributed to the interband transitions in the structure. These peaks are red shifted as x is increased above 0 %. The device power conversion efficiency was extracted from the current-voltage characteristics using an AM 1.5 solar simulator. The short circuit current density increased as the x is increased above 0 %. But the overall power conversion efficiency decreased due to decrease in the open circuit voltage. The decrease in open circuit voltage is due strain induced dislocations caused by lattice mismatch.
High Energy Density, High Operating Frequency and Energy Efficient On-Chip Inductors based on Coiled Carbon Nanotubes (CCNTs)
Authors: Faraby H. , Bandaru P. R. 
Published: June 2019

ABSTRACTWe demonstrate the superior inductive properties of coiled carbon nanotubes (CCNTs) through numerical computation and analytical modeling, for the next generation of nanoscale, on-chip inductors. Taking advantage of the kinetic inductance (Lk), particularly evident at the nanoscale we find that the inductance can be increased by three orders of magnitude through changing the tube radius as well as the coil radius while the device footprint of the CCNTs can be reduced by 60%. By varying the geometric parameters of the coiled structure, the external magnetic inductance (LM,ext) can be as high as 20% of the Lk. We also report that the self resonant frequency (fSR) of CCNTs can be as much of the order of THz whereas the fSR of conventional copper(Cu) spiral inductors are limited to around 40GHz. Moreover when the material volume is considered, CCNTs have the potential to achieve Quality Factor (Q) eight times as Cu and when the footprint volume is considered Q can be twice as Cu All these promising properties of CCNTs make them a potential candidate for the entire frequency spectrum.

Published: June 2019

ABSTRACTThe device performance of GaAs p-i-n solar cells containing stacked layers of self-assembled InAs quantum dots is investigated. The solar cells demonstrate enhanced external quantum efficiency below the GaAs band gap relative to a control device without quantum dots. This is attributed to the capture of sub-band gap photons by the quantum dots. Analysis of the current density versus voltage characteristic for the quantum dot solar cell reveals a decrease in the series resistance as the device area is reduce from 0.16 cm2 to 0.01 cm2. This is effect is not observed in control devices and is quantum dot related. Furthermore, low temperature measurements of the open circuit voltage for both quantum dot and control devices provide experimental verification of the conditions required to realise an intermediate band gap solar cell.
Reactive Laser–Sputtering for Amorphous Silicon Films
Authors: Hanabusa M. , Suzuki M. 
Published: June 2019

ABSTRACTIntense, Q-switched Nd:YAG laser pulses were used to vaporize a silicon target. The pulsed atomic vapor generated produces amorphous silicon films at unusually fast accumulation speeds of 106 Å/s. Despite this speed, reactive deposition is made possible simply by evaporating in a reactive gas atmosphere. For instance, hydrogenated films have been produced by evaporating in hydrogen. Atomic hydrogen generated by thermal decomposition at a laserirradiated target spot is responsible for hydrogenation. Dynamics of this laser-induced deposition have been studied by a spectroscopic technique.
Evaluation of a Thermoelectric Device Utilizing Porous Medium
Authors: Yasuda Hideyuki , Ohnaka Itsuo , Inada Yoichi , Nomura Kimitaka 
Published: June 2019

ABASTRACT:A thermoelectric device consisting of the porous part and the bulk part was proposed. Increase of heat exchange area due to porous medium will improve the efficiency of heat exchange between heating/cooling sources and the device. Estimation based on physical properties of FeSi2 indicated that generated power of the partially porous device per unit area can be several times higher than that of the bulk one in case of gas heating / cooling system. The partially porous thermoelectric devices were produced. In measurement of power, it has been confirmed that generated power per unit area of the partially porous FeSi2 devices was roughly 10 times higher than that of the conventional device. The proposed porous device will exhibit its advantage in the case of low heat transfer coefficient between the device and the heating / cooling sources.
Synthesis and Characterization of Large Single Crystals of Silicon and Germanium Clathrate-II Compounds and a New Tin Compound with Clathrate Layers
Authors: Bobev Svilen , Sevov Slavi C. 
Published: June 2019

ABSTRACTWe have synthesized large single crystals of clathrate-II compounds with frameworks of silicon and germanium by employing mixed alkali metal countercations. The combinations of alkali metals are rationally selected in order to fit the different cages of the clathrate-II structure. This approach leads to the following stoichiometric and fully “stuffed” compounds: Cs8Na16Si136, Cs8Na16Ge136, Rb8Na16Si136 and Rb8Na16Ge136. The structures and the corresponding Si-Si and Ge-Ge distances are elucidated and established with high accuracy from extensive single crystal X-ray diffraction work. The compounds are stoichiometric, metallic, and are very stable at a variety of extreme conditions such as heat, concentrated acids, hydrothermal treatment etc. No evidence was found for vacancies in the silicon and germanium networks or partial occupancies of the alkali metal sites. The stoichiometry of these fully “stuffed” clathrates is consistent with the measured temperature independent Pauli paramagnetism, supported also by the conductivity measurements on single crystals and thermopower measurements on pellets. A new compound with novel clathrate-like structure forms when small and large cations are combined with tin. The new materials, A6Na18Sn46 (A = K, Rb, Cs), are made of clathrate layers and the interlayer space filled with Sn4-tetrahedra and alkali-metal cations. Its formula can be rationalized as A6Na6Sn34 + 3·Na4Sn4 (one clathrate layer and three tin tetrahedra). The compound is stable in air and is being currently tested at other conditions. Detailed measurements of its transport properties are under way.

ABSTRACTWe report artificially atomic-scale ordered superlattice alloy systems, new scheme to pursue high-ZT materials. We have fabricated Bi/Sb superlattice alloys that are artificially ordered on the atomic scale using MBE, confirmed by the presence of XRD superlattice satellites. We have observed that the electronic structure can be modified from semimetal, through zero-gap, to semiconductor by changing the superlattice period and sublayer thicknesses using electrical resistivity, thermopower, and magneto-transport measurements. InSb/Bi superlattice alloys have also been prepared and studied using XRD and thermopower measurements, which shows that their thermoelectric transport properties can be modified in accordance with structural modification. This superlattice alloy scheme gives us one more tool to control and tune the electronic structure and consequently the thermoelectric properties.

Published: June 2019

ABSTRACTBased on the versatile combination of PbQ- and Bi2Q3-type (Q = S, Se, Te) fragments, we explored new compounds in the Pb/Bi/Se ternary system. The new class of compounds, Pb5Bi6Se14, Pb5Pb12Se23, and PbBi8Se13 are homologues with different combination of alternating Bi2Se3- and PbSe-type layers. α- and β-Pb6Bi2Se9 were obtained in different synthetic conditions and the former is isostructural to heyrovskyite (Pb6Bi2S9) while the latter is a NaCl-type cubic phase. Pb5Bi6Se14 shows a power factor of 11.2 μW/cm·K2 with electrical conductivity of 657 S/cm and thermopower of -131 μV/K at 271 K. The most significant characteristic of this material is the extremely low thermal conductivity of less than 1.0 W/m·K at room temperature. On the basis of these properties, a preliminary doping study for Pb5Bi6Se14 with Sn, Sb, and SbBr3 as dopants was undertaken and the results are presented in this report.
Exploring Complex Chalcogenides for Thermoelectric Applications
Authors: Wang Ying C. , DiSalvo Francis J. 
Published: June 2019

ABSTRACTOur research on ternary / quaternary chalcogenides for thermoelectric applications has lead to the identification of new interesting compounds and better understanding of the chemistry and physical properties of complex chalcogenides. The chemical, geometric, electronic diversity and flexibility has been well demonstrated in BaBiSe3 and Sr4Bi6Se13 type compounds. This presents both a challenge and more opportunity in controlling and optimizing the thermoelectric properties of these complex chalcogenides, compared with elemental and binary compounds. The importance of multivalley band structure in thermoelectric materials is emphasized. Only compounds with high crystal symmetry have the possibility of having a large number of degenerate valleys in the conduction bands or peaks in the valence bands, respectively. However, most of the complex chalcogenides crystallize in low crystal symmetry. An Edisonian method of exploratory synthesis and characterization may be the working approach to find good thermoelectric materials with ZT higher than 4.

ABSTRACTWe present the structure and thermoelectric properties of the new quaternary selenides K1+xM4–2xBi7+xSe15 (M = Sn, Pb) and K1-xSn5-xBi11+xSe22. The compounds K1+xM4-2xBi7+xSe15 (M= Sn, Pb) crystallize isostructural to A1+xPb4-2xSb7+xSe15 with A = K, Rb, while K1-xSn5-xBi11+xSe22 reveals a new structure type. In both structure types fragments of the Bi2Te3-type and the NaCl-type are connected to a three-dimensional anionic framework with K+ ions filled tunnels. The two structures vary by the size of the NaCl-type rods and are closely related to β-K2Bi8Se13 and K2.5Bi8.5Se14. The thermoelectric properties of K1+xM4-2xBi7+xSe15 (M = Sn, Pb) and K1-xSn5-xBi11+xSe22 were explored on single crystal and ingot samples. These compounds are narrow gap semiconductors and show n-type behavior with moderate Seebeck coefficients. They have very low thermal conductivity due to an extensive disorder of the metal atoms and possible “rattling” K+ ions.
