Professionals in care and criminal justice cross boundaries for values-based cooperation to treat domestic violence
This article concerns an experiment involving three learning communities of professionals cooperating across institutional boundaries to address domestic violence cases in multiple complementary ways. Providers of social services interacted with law enforcement in a juridical context to achieve an integrated approach. This alliance indicates the potential for values-based Good Work based on safety, professional care, and compassionate treatment. Playing with time and capacity can be a strategy, and each professional can benefit from multiple viewpoints for recognising and anticipating patterns of domestic violence before it (re)occurs.A lack of funding has suspended embedding this Good Work, slowing progress toward achieving long-term goals and making this interdisciplinary approach to assuring sustainable safety unavailable to prevent repeated outbreaks of domestic violence.

The article is dedicated to the study of heat exchangers operation. The main goal of the work was to improve a standard method for calculating a typical heat exchanger based on dependencies approved in engineering practice. The noted technique is presented in educational literature for chemical engineers and it is included in the educational process for the training of engineers. On the basis of practical recommendations stated in literature the working formulas of the process are taken in approximate form. Further, a correction is calculated, which, as calculations show, leads (together with the initial approximation) to an almost exact satisfaction of the initial equations. It is expedient because traditional equations of a heat transfer have not really high precision, which is determined by the processing of numerous experiments. These experiments are rather rough. It is reasonable that the accuracy of the analysis has to be consistent with the model accuracy. This factor justifies the need to simplify the models (use of various recommendations based on the experience of equipment operation, etc.). At the same time, it is desirable to simplify the mathematical model equation so that it is possible to calculate the corrections, i.e. to clarify the solution. We clarify the equation solution meaning more and more exact satisfaction with the initial equation of the mathematical model. In this direction, various variants of perturbation methods can be used. The search for analytical solutions is complicated by the fact that the equations of the mathematical model of energy transfer in a heat exchanger are nonlinear. The three-layer heat transfer problem in a stationary mode is considered. The first layer is the space of the heat exchanger where a phase transition (first heat transfer agent vapor condensation) occurs. The second layer is the space of the heat exchanger where convective movement of the second heat transfer agent takes place without phase transition. The third layer is a wall separating the heat transfer agent providing some resistance to the heat transfer process. As a result of the simplified model analysis, it became possible to obtain an analytical solution to the problem with such accuracy that the calculated correction turned out to be insignificant i.e. the correction is not appropriate to take into account. The solution found was almost exactly approximated by a simple analytic dependence.

Published: August 2018

AbstractAn overview on the properties and applications of polymer and inorganic planar 1D photonic crystals fabricated from solution is provided here. In the last decades, photonic crystals became technologically relevant for light management, photovoltaics, sensing, and lasing. Such structures are traditionally produced by lithographic and vacuum techniques, but the need to reduce costs and to scale‐up the fabrication have lead the research toward new materials, simplified structures, and low‐cost mass scale growth processes. In this regard, polymer and inorganic mesoporous distributed Bragg reflectors fabricated from solution attracted considerable technological interest. This review focuses on the properties of such structures, concentrating on state‐of‐the‐art fabrication and applications.

Published: August 2018

AbstractBiotechnological strategies using renewable materials as starting substrates are a promising alternative to traditional oleochemical processes for the isolation of different fatty acids. Among them, long chain mono‐unsaturated fatty acids are especially interesting in industrial lipid modification, since they are precursors of several economically relevant products, including detergents, plastics and lubricants. Therefore, the aim of this study was to develop an enzymatic method in order to increase the percentage of long chain mono‐unsaturated fatty acids from Camelina and Crambe oil ethyl ester derivatives, by using selective lipases. Specifically, the focus was on the enrichment of gondoic (C20:1 cisΔ11) and erucic acid (C22:1 cisΔ13) from Camelina and Crambe oil derivatives, respectively. The pursuit of this goal entailed several steps, including: (i) the choice of a suitable lipase scaffold to serve as a protein engineering template (Candida antarctica lipase A); (ii) the identification of potential amino acid targets to disrupt the binding tunnel at the adequate location; (iii) the design, creation and high‐throughput screening of lipase mutant libraries; (iv) the study of the selectivity towards different chain length p‐nitrophenyl fatty acid esters of the best hits found, as well as the analysis of the contribution of each amino acid change and the outcome of combining several of the aforementioned residue alterations and, finally, (v) the selection and application of the most promising candidates for the fatty acid enrichment biocatalysis. As a result, enrichment of C22:1 from Crambe ethyl esters was achieved either, in the free fatty acid fraction (wt, 78%) or in the esterified fraction (variants V1, 77%; V9, 78% and V19, 74%). Concerning the enrichment of C20:1 when Camelina oil ethyl esters were used as substrate, the best variant was the single mutant V290W, which doubled its content in the esterified fraction from approximately 15% to 34%. A moderately lower increase was achieved by V9 and its two derived triple mutant variants V19 and V20 (27%).magnified image

AbstractCertain types of cells possess unique characteristics such as tumor homing and prolonged circulation in blood, which are worthy of being exploited in drug delivery carriers for cancer therapy. To improve the delivery efficiency, these cells are integrated with artificial nanocarriers and therapeutic agents to construct biomimetic drug delivery systems. This report provides an overview of recent advances in cell‐derived drug delivery systems for effective cancer treatment. The natural membranes of cells like red blood cells, cancer cells, leukocytes, stem cells, and so on, are extracted and used to form cell membrane–camouflaged nanocarriers, which take advantage of the outstanding biocompatibility and versatile functions of cell membranes. In addition, as an emerging field, biomimetic drug delivery platforms utilizing living cells are also introduced. Finally, the limitations of biomimetic drug delivery systems and the future outlook are discussed and proposed herein.

AbstractDevelopment of small‐molecule‐based multi‐luminescent fluorophores utilizing simple synthetic methodologies, as well as easily available starting materials, has gained much attention in recent years. Herein, we disclose an efficient protocol for the synthesis of N‐protected 1H‐indazole derivatives with diverse substituents at their 3‐ and 5‐positions via palladium‐catalyzed reactions of hydrazones and p‐benzoquinones. The obtained 1H‐indazole derivatives can be easily modified into donor‐acceptor (D−A)‐type chromophores (Indazo‐Fluors) with tunable emission properties in both solid and solution state. Owing to the extent of intramolecular charge transfer, Indazo‐Fluors exhibit positive solvatochromic emission spanning from blue‐green to orange‐red. Theoretical studies were undertaken to rationalize the observed trends in the optical properties of Indazo‐Fluors. Finally, a triethylene glycol (TEG) appended Indazo‐Fluor exhibiting a large Stokes shift and low cytotoxicity allowed us to use it for cell imaging.

AbstractIntroductionFirst‐trimester ultrasound is widely accepted as part of standard care in many countries. With improvements in equipment, expertise and increasing number of technical studies describing imaging techniques, the detection rate for major fetal anomalies in the first trimester continues to rise and can be as high as 60% in high‐risk populations.MethodsWe set out to create a systematic pictorial guide for trained ultrasound providers to describe the common anatomical structures that are identifiable in the first trimester with provided images. In addition to normal anatomical structures, a number of anomalies with high detection rates are listed.ConclusionA large proportion of the major fetal abnormalities can be detected in the first trimester. A systematic approach is essential to ensure that anomalies are equally likely to be detected for patients of any risk background.

Published: August 2018

AbstractIonic‐liquid gating has become a popular tool for tuning the charge carrier densities of complex oxides. Among these, the band insulator SrTiO3 is one of the most extensively studied materials. While experiments have succeeded in inducing (super)conductivity, the process by which ionic‐liquid gating turns this insulator into a conductor is still under scrutiny. Recent experiments have suggested an electrochemical rather than electrostatic origin of the induced charge carriers. Here, experiments probing the time evolution of conduction of SrTiO3 near the glass transition temperature of the ionic liquid are reported. By cooling down to temperatures near the glass transition of the ionic liquid, the process develops slowly and can be seen to evolve in time. The experiments reveal a process characterized by waiting times that can be as long as several minutes preceding a sudden appearance of conduction. For the conditions applied in our experiments, a consistent interpretation in terms of an electrostatic mechanism for the formation of a conducting path at the surface of SrTiO3 is found. The mechanism by which the conducting surface channel develops relies on a nearly homogeneous lowering of the surface potential until the conduction band edge of SrTiO3 reaches the Fermi level of the electrodes.

Published: August 2018

AbstractA highly efficient copper‐mediated aromatic pentafluoroethylation method using TMSCF3 as the sole fluoroalkyl source is described. The reaction proceeds by a key C1 to C2 process, that is, the generation of CuCF3 from TMSCF3, followed by a subsequent spontaneous transformation into CuC2F5. Various aryl iodides were pentafluoroethylated with the TMSCF3‐derived CuC2F5. This method represents the first practical and efficient method for pentafluoroethylation of aryl iodides using commercially available TMSCF3 as a pentafluoroethyl precursor.

Published: August 2018

ABSTRACTIn this article, we report the synthesis of crosslinked polyacrylamide‐hydrogel‐coated iron oxide (Fe3O4–PAM) magnetic nanoparticles as a kind of novel and efficient solvent‐dehydrating agent. With the use of commercially available toluene (containing trace water at 168–173 ppm) as a model organic solvent, an excellent dehydration performance of Fe3O4–PAM was observed; trace water as low as 48 ppm was efficiently removed, and this desiccant could compete with respect to the dehydration efficiency with common sodium treatments. To our knowledge, this is the first example of the application of such water‐swollen hydrogel‐coated Fe3O4 magnetic nanoparticles for the efficient removal of trace water in solvents. Also, the Fe3O4–PAM magnetic nanoparticles could be easily separated from the solvents after the dehydration treatment; thus, they possess a great advantage over traditional organic solvent dry methods and may find a variety of applications, for example, in oil dehydration and organic solvent drying. © 2018 Wiley Periodicals, Inc.

Published: August 2018

ABSTRACTIn this paper, a chitosan (CS)/glycerol (GL) composite film was prepared, and the solution‐responsive feature of the composite film in a mixed water/ethanol solution was investigated. The composite film began to show obvious shape recovery behavior when the water content of the mixed solution was more than 50% v/v. In mixed solutions, when the molar ratio of water molecules and ethanol molecules was more than 2:1, apart from the combination with the ethanol molecules, the residual water molecules could interact with the CS molecules, promoting the formation of hydrogen bonds. The stress stored in CS molecules was released, and the shape memory effect of the composite film was triggered. In addition, the effect of water content in the mixed solutions on the structural, crystal, thermal stability and mechanical properties of the composite film was characterized. © 2018 Wiley Periodicals, Inc.

Synthesis of Bifunctional Catalysts for Metal‐Air Batteries Through Direct Deposition Methods
Authors: Xiong Ming , Ivey Douglas G. 
Published: August 2018

AbstractRechargeable metal‐air batteries, such as Li‐air and Zn‐air batteries, have gained renewed interest because of their high theoretical energy density, safety and low cost. The air electrode, with bifunctional electrocatalysts for the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER), plays the most important role in determining battery performance. Direct deposition of catalysts on the air electrode, using methods such as electrodeposition, electroless deposition, chemical vapor deposition (CVD) and physical vapor deposition (PVD), is shown to be a viable way to fabricate durable and active catalysts with high efficiency and low cost. This review examines recent research activities which apply direct deposition methods to prepare bifunctional catalysts. The benefits and drawbacks of these methods are compared to provide guidelines for their application.
School‐based support for children with conduct disorders; a qualitative longitudinal study of high‐need families
Authors: Stevens Madeleine 
Published: August 2018

Primary school‐aged children with conduct problems are at risk of future antisocial and criminal behaviour, particularly when there are additional family‐level risk factors. However, little is known about how school‐related factors can reduce that risk. This qualitative longitudinal study investigates school‐related influences on changes in the behaviour of at‐risk children in high‐need families over a period of 5 years. Families of 11 children with serious behaviour problems were followed over the transition to secondary school. In‐depth interviews with mothers, and with practitioners who support the child or family, explored school‐related factors which appeared helpful or unhelpful in improving children's behaviour over time.The analysis found that the disjuncture between the nurture experienced at primary school and a lack of nurture later at secondary school was problematic. Children tended to change primary school until they found one prepared to offer them a high level of nurture and supervision. Consistent relationships with supportive adults were important, but were rare after the transfer to secondary school. Literacy problems remained unrecognised or unaddressed for too long, contributing to children's lack of engagement. Inconsistent disciplinary responses to minor behaviour issues tended to escalate problems and most children were eventually excluded from mainstream education. Communication between parents and school staff was often problematic; parents sometimes experienced school contacts as burdensome, ill‐informed and unsupportive. However, good communication could aid development of successful approaches to supporting children with difficult behaviour.

Published: August 2018

AbstractBackgroundPrevious studies have successfully used augmented reality (AR) as an aid to exposure‐based treatments for anxiety disorders. However, to the best of our knowledge, none of these studies have measured the physiological correlates of the fear response, relying solely on self‐reports and behavioral avoidance tests.MethodsAs the physiological defensive reactivity pattern impacts on the treatment effectiveness, we tested the feasibility of an AR system integrated in a mobile and wearable device for assessing the psychophysiological mechanisms (heart rate) involved in fear responses in real‐life contexts. Specific phobia was used as a model given its prototypical defensive hyperreactivity toward the feared stimulus (spiders to spider phobics, in the current study).ResultsThe results showed that the stimuli presented using AR were able to induce physiological alterations in the participants, which were specific depending on the stimulus type (fear or neutral) and on the participants’ level of spider fear (phobic and control group). These physiological correlates of the fear response were reflected both in the intensity of heart rate (in relation to the baseline) and in the time needed to react and recover after the stimulus exposure. Finally, we tested a theoretical model that showed that the physiological responses of phobic individuals when facing their phobic stimulus only explained its own data.ConclusionsWe argue in favor of the system's feasibility at capturing and quantifying the physiological dimension of fear‐related responses, which may be of great value for diagnostic and treatment purposes in anxiety disorders, namely specific phobia.
