Carbon foils for space plasma instrumentation
Authors: Allegrini F. , Ebert R. W. , Funsten H. O.
Published: May 2016

Carbon foils have been successfully used for several decades in space plasma instruments to detect ions and neutral atoms. These instruments take advantage of two properties of the particle‐foil interaction: charge conversion of neutral atoms and/or secondary electron emission. This interaction also creates several adverse effects for the projectile exiting the foil, such as angular scattering and energy straggling, which usually act to reduce the sensitivity and overall performance of an instrument. The magnitude of these effects mainly varies with the incident angle, energy, and mass of the incoming projectile and the foil thickness. In this paper, we describe these effects and the properties of the interaction. We also summarize results from recent studies with graphene foils, which can be made thinner than carbon foils due to their superior strength. Graphene foils may soon replace carbon foils in space plasma instruments and open new opportunities for space research in the future.
A set‐membership approach to integrated trade‐off design of robust fault detection system
Authors: Zhai Shouchao , Wan Yiming , Ye Hao
Published: May 2016

In order to improve fault detection (FD) performance, integrated design of residual generation and evaluation is investigated in this paper for trade‐offs between fault detection rate and false alarm rate (FAR). A set‐membership approach is proposed in residual evaluation by adopting a threshold ellipsoid, which enables more design freedom than a conventional threshold value. With the set‐based definitions of fault detection rate and FAR, the integrated design problem is formulated by maximizing the FD performance under a predefined FAR. The joint optimal selection of a residual generator and a threshold ellipsoid is equivalently transformed into a simplified optimization problem of determining an optimal threshold ellipsoid for any given residual generator. A suboptimal solution for the set‐membership‐based integrated FD system design is obtained based on approximated computation of the FD performance. Monte Carlo simulations show the performance improvement of the proposed method compared with an existing integrated design method. Copyright © 2016 John Wiley & Sons, Ltd.
Theoretical model for multiple breakup of fluid particles in turbulent flow field
Authors: Razzaghi Kiyanoosh , Shahraki Farhad
Published: May 2016

Generalized phenomenological model, based on the theories of probability and isotropic turbulence, is developed for multiple breakup of fluid particles in turbulent flow field. The approach uses a series of successive binary breakup events occur at a time scale comparable to the colliding eddy turnover time. It was found that the use of energy density, instead of energy, will increase the predicted binary breakup rate which is usually underestimated by the existing models in the literature. Generalization of the binary breakup model for multiple fragmentations is performed by defining a “remaining energy function” for the colliding eddy which means the contribution of original eddy to the later breakup events. For ternary breakage, the model shows a reasonably good agreement with the experimental data. The quaternary fragmentation frequency, however, is of negligible importance at lower energy dissipation rates but its contribution to breakage fraction at higher energy dissipation rates becomes considerable. The results also show that ternary and quaternary breakups have a considerable 90% contribution to the overall fragmentation, while pentenary and further fragmentations are of lower importance at low energy dissipation rates. At higher levels of energy dissipation rate, fragmentations up to six daughter particles contribute to more than 95% of the overall fragmentations. © 2016 American Institute of Chemical Engineers AIChE J, 62: 4508–4525, 2016
In‐situ cross‐linked PVDF membranes with enhanced mechanical durability for vacuum membrane distillation
Authors: Zuo Jian , Chung Tai‐Shung
Published: May 2016

A novel and effective one‐step method has been demonstrated to fabricate cross‐linked polyvinylidene fluoride (PVDF) membranes with better mechanical properties and flux for seawater desalination via vacuum membrane distillation (VMD). This method involves the addition of two functional nonsolvent additives; namely, water and ethylenediamine (EDA), into the polymer casting solution. The former acts as a pore forming agent, while the latter performs as a cross‐linking inducer. The incorporation of water tends to increase membrane flux via increasing porosity and pore size but sacrifices membrane mechanical properties. Conversely, the presence of EDA enhances membrane mechanical properties through in‐situ cross‐linking reaction. Therefore, by synergistically combining the effects of both functional additives, the resultant PVDF membranes have shown good MD performance and mechanical properties simultaneously. The parameters that affect the cross‐link reaction and membrane mechanical properties such as reaction duration and EDA concentration have been systematically studied. The membranes cast from an optimal reaction condition comprising 0.8 wt % EDA and 3‐hour reaction not only shows a 40% enhancement in membrane Young's Modulus compared to the one without EDA but also achieves a good VMD flux of 43.6 L/m2‐h at 60°C. This study may open up a totally new approach to design next‐generation high performance MD membranes. © 2016 American Institute of Chemical Engineers AIChE J, 62: 4013–4022, 2016
Applicability of the linearized theory of the Maxwell–Stefan equations
Authors: Weber Paul S. , Bothe Dieter
Published: May 2016

The present article aims for a better understanding of the applicability of the linearized theory of the Maxwell–Stefan equations for multi‐component diffusion. An analysis of the theory's accuracy is performed with respect to the classical two‐bulb diffusion experiments by Duncan and Toor, from which the results are transferred to more general scenarios. It is shown that for an accurate linearized theory it is essential to have a quasi‐stationary and quasi‐one‐dimensional flux, and also a so‐called reference point. Two examples illustrating the theory's failure in case of unmet prerequisites are presented: a three‐bulb configuration and a two‐dimensional diffusion case. For the first setup the linearized theory results in negative concentrations, for the second it requires influxes at openings that are actually outlets. © 2016 American Institute of Chemical Engineers AIChE J, 62: 2929–2946, 2016
Alternative Knowledges and the Future of Community Psychology: Provocations from an American Indian Healing Tradition
Authors: Gone Joseph P.
Published: May 2016

In the early years of this globalized century, alternative health knowledges and wellness traditions circulate faster and farther than ever before. To the degree that community psychologists seek collaboration with cultural minority and other marginalized populations in support of their collective wellbeing, such knowledges and traditions are likely to warrant attention, engagement, and support. My purpose in this article is to trace an epistemological quandary that community psychologists are ideally poised to consider at the interface of hegemonic and subjugated knowing with respect to advances in community wellbeing. To this end, I describe an American Indian knowledge tradition, its association with specific indigenous healing practices, its differentiation from therapeutic knowledge within disciplinary psychology, and the broader challenge posed by alternative health knowledges for community psychologists.
Gasification of torrefied kitchen waste: release of sodium and its influence on the formation of gasification products
Authors: Chen Zhenguo , Liu Shuai , Qiao Yu , Wang Wenxia , Sun Qiqi , Zhang Ke , Zhou Junbo , Yu Jie , Xu Minghou
Published: May 2016

Six kitchen wastes of raw, acid‐washed, NaCl‐loaded, Na2CO3‐loaded, NaB‐loaded, and Na‐exchanged noodles were torrefied at 300 °C. The six torrefied noodle samples were then gasified in air (equivalence ratio = 0.2) at 600, 800, and 1000 °C, respectively. The results suggest sodium could significantly increase the production of CO and H2. For Na‐exchanged noodles, the yields of CO and H2 at 1000 °C were 0.39 and 0.30 Nm3/kg, respectively, much higher than that of 0.29 and 0.20 Nm3/kg for acid‐washed noodle. Meanwhile, sodium could accelerate the decomposition of liquid, particularly for the polycyclic aromatic hydrocarbons. The catalytic effect of sodium as ion‐exchanged form is stronger than that of sodium in H2O‐soluble form. Among the H2O‐soluble sodium compounds, Na2CO3 shows the best catalytic effect. When torrefied noodle samples were gasified, the amounts of sodium as CH3COONH4‐soluble and H2O‐soluble forms were reduced from 48.4% and 18.3% of torrefied noodle sample to 5.1% and 5.9% of gasified noodle sample at 600 °C, indicating that the CH3COONH4‐soluble sodium had the higher volatility than H2O‐soluble sodium. © 2016 Curtin University of Technology and John Wiley & Sons, Ltd.
RNA assemblages orchestrate complex cellular processes
Authors: Nielsen Finn Cilius , Hansen Heidi Theil , Christiansen Jan
Published: May 2016

Eukaryotic mRNAs are monocistronic, and therefore mechanisms exist that coordinate the synthesis of multiprotein complexes in order to obtain proper stoichiometry at the appropriate intracellular locations. RNA‐binding proteins containing low‐complexity sequences are prone to generate liquid droplets via liquid‐liquid phase separation, and in this way create cytoplasmic assemblages of functionally related mRNAs. In a recent iCLIP study, we showed that the Drosophila RNA‐binding protein Imp, which exhibits a C‐terminal low‐complexity sequence, increases the formation of F‐actin by binding to 3′ untranslated regions of mRNAs encoding components participating in F‐actin biogenesis. We hypothesize that phase transition is a mechanism the cell employs to increase the local mRNA concentration considerably, and in this way synchronize protein production in cytoplasmic territories, as discussed in the present review.
Losses distribution in sheathed power cables under non‐sinusoidal currents using numerical method
Authors: Rasoulpoor Masoumeh , Mirzaie Mohammad , Mirimani Seyyed Mehdi
Published: May 2016

This paper presents losses distribution in power cables conductors and metallic sheaths. Losses are computed in sinusoidal and non‐sinusoidal currents with considering all sequences harmonics. Two numerical methods as finite element and integral method are used to determine the distributions and also total harmonic losses. Thus skin and proximity effects of all metallic parts of cables are considered accurately. Integral method is utilized for losses calculation by considering of earth return path and eliminating it. Furthermore, IEC formulations are used for losses computations. Numerical results suggest inserting the earth return path effect on cable losses in some harmonic frequencies of currents. Power cables are assumed to be single core medium voltage type. Lead sheaths of cables are bonding together and grounded at both ends for calculation of circulating current losses. Also the effects of different distances between cables in losses calculations are assessed. For validation of integral method, finite element simulation, as proven method in accurate power cable losses computations is used. These methods are completely described in this paper. Accuracy of integral method for harmonic losses computations of conductor and sheaths is verified by finite element simulation results. Also it is shown that proximity and skin effects are considered very well by integral method even in metallic sheaths. © 2016 Wiley Periodicals, Inc.

An ontological learning management system
Authors: Rani Monika , Srivastava Kumar Vaibhav , Vyas Om Prakash
Published: May 2016

The current learning systems typically lack the level of meta‐cognitive awareness, self‐directed learning, and time management skills. Most of the ontologically based learning management systems are in the proposed phase and those which are developed do not provide the necessary path guidance for proper learning. The systems available are not as adaptive from the viewpoint of the learner as required. Ontology engineering has become an important pillar for knowledge management and representation in recent years. The design, approach, and implementation of ontology in e‐ and m‐learning systems have made them more effective. In this paper, we have proposed a system for the betterment of knowledge management and representation of associated data as compared to the previously available learning management systems. Here, we have presented the application and implementation of ontological engineering methodology in the Computer Science domain. For knowledge management, we have created a domain associated ontology which represents knowledge of a single domain. Subsequently, ontology has been created to manage a learner profile so that a learner may be aligned to a proper path of learning. The learner ontology will use the VARK learning model which classifies what kind of learning does the learner requires so that necessary resources could be provided. © 2016 Wiley Periodicals, Inc.

Published: May 2016

We design dynamic k‐d (DKD) tree based on classical k‐d tree for animated scene rendering. Our method can inherit the benefit of efficient traversal of k‐d tree and minimize time cost to update DKD tree, making it well suited for animated geometry. DKD employs primitive reset, redistribution to reflect the updated positions of geometry, and leaf node incremental growing to avoid the deterioration of hierarchy quality due to refitting. Our experiments show that DKD has a significant rendering performance improvement than selected existing methods. Copyright © 2016 John Wiley & Sons, Ltd.

Size‐Dependent Cytotoxicity of Thiolated Silver Nanoparticles Rapidly Probed by using Differential Pulse Voltammetry
Authors: Yang Jie , Liao Lingwen , Wang Juan , Zhu Xiaoguang , Xu An , Wu Zhikun
Published: May 2016

Thiolated silver nanoparticles have recently received extensive interests in terms of their syntheses, properties, and applications; however, their cytotoxicity has not been paid great attention. Some issues related to the cytotoxicity remained unresolved: What is the relationship between size and cytotoxicity? How to rapidly probe their cytotoxicity?, and so forth. In this work, differential pulse voltammetry (DPV) is, for the first time, introduced to rapidly and preliminarily evaluate the cytotoxicity of silver nanoparticles on the basis of the finding that the silver‐ion signal intensity probed by DPV is positively correlated to the cytotoxicity of silver nanoparticles. It is found that the cytotoxicity of silver nanoparticles is size dependent in the investigated size range, that is, with increasing size, the cytotoxicity increases. Our work advances one step toward monitoring and understanding the cytotoxicity of thiolated silver nanoparticles.
