Published: September 2017

An experimental investigation of breakup mechanism in a rotary atomizer with square shape discharge orifice atambient condition has been performed. The effects of a high aspect ratio noncircular discharge channels, particularly a square shape discharge channel, are considered. The motivation of this study is the use of this type of orifice in some small gas turbine engines as well as non-existing observation in literature concerning about high aspect ratio of discharge channel. Visualization experiments are conducted by high speed shadowgraph imaging technique with pulsed light illumination for the first time. The effects of rotational speed and volume flow rate are studied on the breakup structure. The visualizations indicates that the liquid film formed along the channel is pushed to one side of it due to Coriolis force which is dominant in this type of atomizer. Accordingly a crescent shaped liquid film is formed at the square channel exit covering two corners of the square, resulting the combination of Coriolis induced stream mode and surface tension induced stream mode breakup. Observations of the breakup process for different volume flow rates and rotational speeds indicate that the breakup of liquid film stream is dependent on injection conditions and the corresponding cross flow velocity created by atomizer rotation. The breakup regime map is provided as a function of weber number and momentum flux ratio. Four distinct regimes are identified: Rayleigh breakup, bag breakup, multimode breakup, and shear breakup. The present results leads to understandingatomization performance and creating some idea to improved spray quality in this type of atomizer.DOI: http://dx.doi.org/10.4995/ILASS2017.2017.5640

Feedback

Published: September 2017

Abstract. To investigate how differing amounts of experiential feedback and feedback’s availability in an interactive simulation tool influences people’s decision-making against landslide risks. Feedback via simulation tools is likely to help people improve their decisions against disasters; however, currently little is known on how differing amounts of experiential feedback and feedback’s availability in simulation tools influences people’s decisions against landslides. We tested the influence of differing amounts of experiential feedback and feedback’s availability on people’s decisions against landslide risks in an Interactive Landslide Simulation (ILS) tool. In an experiment, in high-damage conditions, the probabilities of damages to life and property due to landslides were 10-times higher than those in the low-damage conditions. In feedback-present condition, experiential feedback was provided in numeric, text, and graphical formats in ILS. In feedback-absent conditions, the probabilities of damages were described; however, there was no experiential feedback present. Investments were greater in conditions where experiential feedback was present and damages were high compared to conditions where experiential feedback was absent and damages were low. Furthermore, only high-damage feedback produced learning in ILS. Experience gained in ILS enables people to improve their decision-making against landslide risks. Simulation tools seem appropriate for landslide risk communication and for performing what-if analyses.
Fraude a la ley y fraude a la ley fiscal: Juegos de estrategias
Authors: Blanco Andrés 
Published: September 2017

Lo que se llama fraude a la ley es una confrontación de estrategias. De un lado,se aprovecha el formalismo de las categorías jurídicas y el modelo argumentativo exegético que impera en la práctica de los juristas para eludir una prohibición legal evitando deliberadamente ingresar en el universo de casos prohibidos. Del otro lado, los que tratan de repeler esa conducta usan una estrategia consistente en la apelación discursiva a fines y principios. Pero las motivaciones de unos y otros están en la prevalencia de sus respectivos intereses, principalmente económicos. El fraude a la ley fiscal de los particulares se produce cuando se usa el formalismo jurídico para defender los intereses de los propietarios
de dinero, a la vez que la Administración confronta ese uso con una estrategia que recubre su interés recaudatorio.

El presente trabajo desarrolla el concepto de la dimensión objetiva de los derechos fundamentales y de cómo tal dimensión se erige como parámetro de legitimidad material
del Estado Constitucional de Derecho. Luego, se analizan dos sentencias del Tribunal Constitucional chileno que recogen precisamente este parámetro de control respecto de:
1) la actividad del legislador; 2) como un argumento a favor del necesario control de la Justicia Constitucional; y 3) como límite de eficacia horizontal y vertical de los derechos fundamentales.
Prediction of endoplasmic reticulum resident proteins using fragmented amino acid composition and support vector machine
Authors: Kumar Ravindra , Kumari Bandana , Kumar Manish 
Published: September 2017

BackgroundThe endoplasmic reticulum plays an important role in many cellular processes, which includes protein synthesis, folding and post-translational processing of newly synthesized proteins. It is also the site for quality control of misfolded proteins and entry point of extracellular proteins to the secretory pathway. Hence at any given point of time, endoplasmic reticulum contains two different cohorts of proteins, (i) proteins involved in endoplasmic reticulum-specific function, which reside in the lumen of the endoplasmic reticulum, called as endoplasmic reticulum resident proteins and (ii) proteins which are in process of moving to the extracellular space. Thus, endoplasmic reticulum resident proteins must somehow be distinguished from newly synthesized secretory proteins, which pass through the endoplasmic reticulum on their way out of the cell. Approximately only 50% of the proteins used in this study as training data had endoplasmic reticulum retention signal, which shows that these signals are not essentially present in all endoplasmic reticulum resident proteins. This also strongly indicates the role of additional factors in retention of endoplasmic reticulum-specific proteins inside the endoplasmic reticulum.MethodsThis is a support vector machine based method, where we had used different forms of protein features as inputs for support vector machine to develop the prediction models. During trainingleave-one-outapproach of cross-validation was used. Maximum performance was obtained with a combination of amino acid compositions of different part of proteins.ResultsIn this study, we have reported a novel support vector machine based method for predicting endoplasmic reticulum resident proteins, named as ERPred. During training we achieved a maximum accuracy of 81.42% withleave-one-outapproach of cross-validation. When evaluated on independent dataset, ERPred did prediction with sensitivity of 72.31% and specificity of 83.69%. We have also annotated six different proteomes to predict the candidate endoplasmic reticulum resident proteins in them. A webserver, ERPred, was developed to make the method available to the scientific community, which can be accessed athttp://proteininformatics.org/mkumar/erpred/index.html.DiscussionWe found that out of 124 proteins of the training dataset, only 66 proteins had endoplasmic reticulum retention signals, which shows that these signals are not an absolute necessity for endoplasmic reticulum resident proteins to remain inside the endoplasmic reticulum. This observation also strongly indicates the role of additional factors in retention of proteins inside the endoplasmic reticulum. Our proposed predictor, ERPred, is a signal independent tool. It is tuned for the prediction of endoplasmic reticulum resident proteins, even if the query protein does not contain specific ER-retention signal.

An Update on the Centered and Eccentric Geomagnetic Dipoles and Their Poles for the Years 1980–2015
Authors: Koochak Zahra , Fraser‐Smith Antony C. 
Published: September 2017

AbstractThis paper is an update and extension of an earlier study of the centered and eccentric dipole models of the Earth's magnetic field. We use the 1980–2015 IGRF Gauss coefficients to recalculate the magnetic dipole moments and pole positions for both the centered and eccentric dipoles for an additional 35 years. The changes that have taken place are mostly extensions of the trends described earlier. Interestingly, the earlier weak suggestion of an accelerated decline in the magnetic moment over the interval 1975–1985 persists in the more recent data; if the current decline for the years 2000–2015 continues, the Earth's field is projected to decline to nothing around the year 3797 A.D. This projected decline to zero field will almost certainly not occur on this date, but it is of interest because the timescale for the decline is remarkably short compared with the timescales derived for past field reversals. The asymmetry of the Earth's field continues to increase quite rapidly, with the offset of the equivalent dipole from the Earth's center now close to 9% of the Earth's radius. Since we now know that all the planets in our solar system with global magnetic fields have asymmetric fields that can be modeled more accurately as eccentric dipole fields, and not as centered dipole fields, the eccentric dipole analysis reported here can now be viewed more generally as an approach to planetary magnetic fields and not just to the magnetic field of our own planet.

AbstractThis paper presents the efficacy of a “tuned” fuzzy logic method at determining the height of the boundary layer using the measurements from a 1280 MHz lower atmospheric radar wind profiler located in Gadanki (13.5°N, 79°E, 375 mean sea level), India, and discusses the diurnal and seasonal variations of the measured convective boundary layer over this tropical station. The original fuzzy logic (FL) method estimates the height of the atmospheric boundary layer combining the information from the range‐corrected signal‐to‐noise ratio, the Doppler spectral width of the vertical velocity, and the vertical velocity itself, measured by the radar, through a series of thresholds and rules, which did not prove to be optimal for our radar system and geographical location. For this reason the algorithm was tuned to perform better on our data set. Atmospheric boundary layer heights obtained by this tuned FL method, the original FL method, and by a “standard method” (that only uses the information from the range‐corrected signal‐to‐noise ratio) are compared with those obtained from potential temperature profiles measured by collocated Global Positioning System Radio Sonde during years 2011 and 2013. The comparison shows that the tuned FL method is more accurate than the other methods. Maximum convective boundary layer heights are observed between ~14:00 and ~15:00 local time (LT = UTC + 5:30) for clear‐sky days. These daily maxima are found to be lower during winter and postmonsoon seasons and higher during premonsoon and monsoon seasons, due to net surface radiation and convective processes over this region being more intense during premonsoon and monsoon seasons and less intense in winter and postmonsoon seasons.

Published: September 2017

AbstractA solid–liquid–vapor interface dominated by a three‐phase contact line usually serves as an active area for interfacial reactions and provides a vital clue to surface behavior. Recently, direct imaging of the triphase interface of superwetting interfaces on the microscale/nanoscale has attracted broad scientific attention for both theoretical research and practical applications, and has gradually become an efficient and intuitive approach to explore the wetting behaviors of various multiphase interfaces. Here, recent progress on characterizing the solid–liquid–vapor triphase interface on the microscale/nanoscale with diverse types of imaging apparatus is summarized. Moreover, the accurate, visible, and quantitative information that can be obtained shows the real interfacial morphology of the wetting behaviors of multiphase interfaces. On the basis of fundamental research, technical innovations in imaging and complicated multiphase interfaces of the superwetting surface are also briefly presented.

Published: September 2017

AbstractRedox‐active catechols are bioinspired precursors for ortho‐quinones that are characterized by higher discharge potentials than para‐quinones, the latter being extensively used as organic cathode materials for lithium ion batteries (LIBs). Here, this study demonstrates that the rational molecular design of copolymers bearing catechol‐ and Li+ ion‐conducting anionic pendants endow redox‐active polymers (RAPs) with ultrarobust electrochemical energy storage features when combined to carbon nanotubes as a flexible, binder‐, and metal current collector‐free buckypaper electrode. The importance of the structure and functionality of the RAPs on the battery performances in LIBs is discussed. The structure‐optimized RAPs can store high‐capacities of 360 mA h g−1 at 5C and 320 mA h g−1 at 30C in LIBs. The high ion and electron mobilities within the buckypaper also enable to register 96 mA h g−1 (24% capacity retention) at an extreme C‐rate of 600C (6 s for total discharge). Moreover, excellent cyclability is noted with a capacity retention of 98% over 3400 cycles at 30C. The high capacity, superior active‐material utilization, ultralong cyclability, and excellent rate performances of RAPs‐based electrode clearly rival most of the state‐of‐the‐art Li+ ion organic cathodes, and opens up new horizons for large‐scalable fabrication of electrode materials for ultrarobust Li storage.
Preparation of Building Blocks for Iterative Suzuki‐Miyaura Reactions via Direct Bromination of Aryl Boronic Acids: One‐Pot Total Syntheses of Dictyoterphenyls A and B

Published: September 2017

AbstractA highly efficient method for the preparation of 4‐alkoxy‐3‐bromophenyl boronic acid N‐methyliminodiacetic acid (MIDA) esters as building blocks in iterative Suzuki‐Miyaura reactions from the 4‐alkoxyphenylboronic acids is described using a boronic acid moiety as a blocking group in bromination reactions. With these MIDA boronates, the total syntheses of dictyoterphenyls A and B were developed in only two separate one‐pot operations. Furthermore, we have developed a more practical protocol for the preparation of meta‐terphenyl natural products by simply adding the second aryl halide and water to the reaction mixture via the controlled release technique.magnified image
Preparation and characterization of starch nanocomposite embedded with functionalized MWCNT: Investigation of optical, morphological, thermal, and copper ions adsorption properties
Authors: Mallakpour Shadpour , Nezamzadeh Ezhieh Ahmadreza 
Published: September 2017

AbstractThe purpose of this research was to fabricate starch nanocomposites (NC)s using corn starch and MWCNTs‐Valine as efficient fillers, and to examine the impact of nanofillers on the starch's properties. At first, Valine was grafted onto the MWCNTs' surfaces through a chemical reaction. Then, the functionalized MWCNTs (0.5, 1, and 2 wt.%) were embedded in the starch by ultrasonic technique. The field emission scanning electron microscopy showed homogeneous distribution of nanofillers in the starch matrix. Moreover, thermogravimetric analysis demonstrated that the starch's thermal stability was improved after addition of MWCNTs. Finally, the adsorption behavior of the prepared NC for the elimination of copper ions from the aqueous solution was investigated.

Authors: Liang Ji‐Zhao , Yang Quan‐Quan 
Published: September 2017

AbstractThe high‐density polyethylene (HDPE) composites filled with four kinds of carbon blacks (CB) were prepared to investigate the effects of the size and content of the CB on the electrical properties of the HDPE/CB composites. It was found that the composites presented conductive percolation behavior, the CB with different size filled‐systems had different percolation thresholds; the higher the structure property of the CB, the larger the particle surface area, and the smaller the particle size, the better was the conductivity, and the lower was the percolation threshold of the composites. In addition, the HDPE/CB composites showed significant positive temperature coefficient (PTC) effect and negative temperature coefficient effect. The bigger the filler particle diameter, the higher was the PTC intensity of the HDPE composite systems under the same CB weight fraction.

AbstractTremendous progress has recently been achieved in the field of perovskite solar cells (PSCs) as evidenced by impressive power conversion efficiencies (PCEs); but the high PCEs of >20% in PSCs has so far been mostly achieved by using the hole transport material (HTM) spiro‐OMeTAD; however, the relatively low conductivity and high cost of spiro‐OMeTAD significantly limit its potential use in large‐scale applications. In this work, two new organic molecules with spiro[fluorene‐9,9′‐xanthene] (SFX)‐based pendant groups, X26 and X36, have been developed as HTMs. Both X26 and X36 present facile syntheses with high yields. It is found that the introduced SFX pendant groups in triphenylamine‐based molecules show significant influence on the conductivity, energy levels, and thin‐film surface morphology. The use of X26 as HTM in PSCs yields a remarkable PCE of 20.2%. In addition, the X26‐based devices show impressive stability maintaining a high PCE of 18.8% after 5 months of aging in controlled (20%) humidity in the dark. We believe that X26 with high device PCEs of >20% and simple synthesis show a great promise for future application in PSCs, and that it represents a useful design platform for designing new charge transport materials for optoelectronic applications.

AbstractThe selective hydrogenation of nitrile groups to primary amines is challenging owing to their high ability to produce secondary and tertiary amines. Herein, we report an efficient system for the hydrogenation of nitrile and nitro groups to primary amines catalyzed by Ni2P nanoparticles in an aqueous H3NBH3 solution under ambient conditions. The system exhibits high catalytic selectivity toward generating primary amines, resulting in good isolated yields. A combination of experiments and theoretical calculations shows that composite interactions among species on the catalyst surface alter the catalytic pathway.

Published: September 2017

AbstractA fabrication strategy for biphasic gels is reported, which incorporates high‐internal‐phase emulsions. Closely packed micro‐inclusions within the elastic hydrogel matrix greatly improve the mechanical properties of the materials. The materials exhibit excellent switchable mechanics and shape‐memory performance because of the switchable micro‐ inclusions that are incorporated into the hydrogel matrix. The produced materials demonstrated a self‐healing capacity that originates from the noncovalent effect of the biphasic heteronetwork. The aforementioned characteristics suggest that the biphasic gels may serve as ideal composite gel materials with validity in a variety of applications, such as soft actuators, flexible devices, and biological materials.
