AimsTo evaluate the impact of the pre‐operative maximum detrusor pressure (MDP) on efficacy outcomes after incontinentation by sphincterotomy or urethral stent placement in male patients with neurogenic detrusor‐sphincter dyssynergia (DSD).MethodsA retrospective study was performed in 41 male patients treated between 2006 and 2013 in a tertiary reference center. All patients had a neurogenic DSD confirmed by baseline urodynamic studies, and were unable or secondary failed to practice CISC. Success was defined as a post‐void residual volume <150 mL. Influence of MDP on treatment efficacy was evaluated through a Mann‐Whitney U‐Test.ResultsMedian (range) age was 39 years (20‐69). Spinal cord injury was the main underlying condition. Twenty‐six patients had a sphincteric stent placement (Memocath®, Bard, Covington) and 15 had surgical sphincterotomy. Treatment was successful in 31 patients (76%). Patients with immediate successful outcomes had a significantly higher mean preoperative MDP (59.6 vs 29.7 cmH2O; P = 0.002). Patients with MDP over the threshold of 40 cmH2O had a 90% success rate. These differences were maintained at 6 months, MDP being higher in the success group than in the failure group (59.5 vs 39.8 cmH2O, respectively, P = 0.008). The technique used (stent placement or incision) had no impact on immediate or 6‐month success rates.ConclusionsOur results suggested that MDP is associated with treatment success rate after surgical management of DSD of neurogenic origin by sphincteric stent placement or surgical sphincterotomy. A threshold of 40 mH2O is associated with higher success rates.

ObjectiveThis study aimed to examine the association between age at solid food (SF) introduction and obesity throughout the life course.MethodsAmong 31,816 mother– nurse daughter dyads in the Nurses' Mothers' Cohort Study and the Nurses' Health Study II, information was collected on age at SF introduction, body somatotype at ages 5 and 10, and Body Mass Index at age 18 and in adulthood. Odds ratios (ORs) and 95% confidence intervals (95% CIs) for obesity throughout life were estimated using logistic regression models with adjustment for parental and nurse daughter covariates.ResultsNurse daughters introduced to SF at ≥ 9 months versus 6 to 9 months had marginally higher age‐adjusted (OR: 1.21; 95% CI: 1.01, 1.47) and covariate‐adjusted (OR: 1.22; 95% CI: 1.01, 1.47) odds of obesity at age 5. Age at SF introduction was not related to obesity at ages 10 and 18 or in adulthood.ConclusionsLate age at SF introduction was marginally associated with obesity at age 5, but this association did not persist throughout the life course.
Improved performance of carbon‐based supercapacitors with sulfonated poly(ether ether ketone)/poly(vinyl alcohol) composite membranes as separators

AbstractSupercapacitors have attracted much interest because of their high power density and long cycling life. However, the porous polypropylene membranes that are widely used as separators in supercapacitors are unfavorable for transporting ions and constructing the interfaces between electrolyte and electrodes due to their hydrophobic property. As a consequence, a crosslinked solid polymer electrolyte membrane and a semi‐interpenetrating polymer network (sIPN) were fabricated from sulfonated poly(ether ether ketone) (SPEEK) and poly(vinyl alcohol) (PVA), which can be used as hydrophilic separators. Their structures were examined using Fourier transform infrared spectroscopy. The electrochemical properties of assembled electrical double‐layer capacitors (EDLCs) were investigated using cyclic voltammetry, galvanostatic charging–discharging and impedance analysis. At a current density of 1 A g−1, a single electrode in the EDLC with the sIPN shows a specific capacitance of 134 F g−1. As a comparison, a single electrode in the EDLC with a SPEEK membrane demonstrates a specific capacitance of only 121 F g−1. After 1000 charge–discharge cycles, the specific capacitance retentions of both EDLCs are nearly 100%. These results suggest that the sIPN based on SPEEK and PVA has great potential to serve as a separator in EDLCs. © 2018 Society of Chemical Industry
Early adulthood housing transitions in Amsterdam: Understanding dependence and independence between generations

Published: September 2018

AbstractThe housing context has a profound influence on how different generations within families negotiate dependence and independence. This article investigates the nature of intergenerational relations during early adulthood housing transitions. We consider an original dataset of qualitative interviews with young adults and their parents living in and around Amsterdam, where recent housing market liberalisation is challenging home‐leaving norms. We find that while strong norms regarding early home‐leaving and independence persist, market conditions prompt significant intergenerational support to sustain this “independence.” Support for renting and homeownership are part of different intergenerational dynamics. The first marks a process of easing into adulthood, whereas the latter solidifies new sets of relationships between fully adult generations supporting one another on equal terms. Despite professed individualization in Western European societies, the analysis of early adulthood housing transitions show that intergenerational dependencies can emerge in specific housing markets, requiring creative approaches to support young adult autonomy.

Published: September 2018

The KMnO4‐H3PO4‐H2SO4 system was used to roughen and hydrophilically modify on the surface of ABS resin at different etching temperatures, and then, electroless nickel plating process was carried out. The surface of ABS resin after etching was characterized by XPS and SEM. It is found that the surface etching effect of ABS resin is relatively good when the etching temperature is 65°C. The resin surface generates ─OH and ─COOH hydrophilic groups, the roughness of resin surface is increased significantly, and the surface hydrophilic contact angle is 40.51°. After electroless nickel plating on the ABS etching surface, the bonding force of the coating can reach 2.73 MPa. Electrochemical polarization curves and electrochemical impedance spectra also show that the corrosion resistance of coating after 65°C etching postprocessing is improved.

AbstractBimetallic nanoparticles (NPs) play a pivotal role in promoting high activity and selectivity towards various industrially important reactions in comparison to single metal NPs due to their modulated electronic and surface properties. Herein, we report the synthesis of non‐precious CoCu NPs, which serve as an excellent catalyst for the selective oxidation of a wide range of electronically diverse benzyl alcohols to benzaldehydes, in the presence of tert‐butyl hydroperoxide (TBHP) as an oxidant at room temperature. The excellent catalytic activity of CoCu NPs is ascribed to a two‐fold synergistic effect arising from the combination of enhanced peroxide decomposition, active Co2+ catalyst regeneration driven by the faster redox processes (between Co3+ and Cu+), and a feasible cobalt dimerisation‐regeneration process. The recoverability and reusability of CoCu NPs are also demonstrated. With the merits of low‐cost and recyclable catalysis under mild conditions, the present catalyst represents an efficient and potential alternative to precious metal catalysts.

Published: September 2018

AbstractNeuromorphic hardware systems that simulate functions of biological brain synapses have been widely investigated due to their possible application in brain‐inspired computing. We hereby report on a novel electrochemical state machine based on Zn:CdS thin films. The memory switching mechanism involves the cation exchange of Cu2+ and Zn2+ acting as inorganic “neurotransmitters”. Similarly to the synapse‐neurotransmitter interactions, Cu2+ ions increase the conductivity and the electrocatalytic activity of Zn:CdS towards the ferrocene/ferrocenium redox process. The cationic substitution of Zn2+ by Cu2+ in the film has shown significant changes in the electrochemical characteristic of the device. Such effects have been investigated with both alternated current (impedance) and direct current (voltammetry and I vs V) measurements. The cation exchange mechanism allows to write and store an electrochemical information into the device. Such information can be gradually erased by exchanging the absorbed Cu2+ ions with Zn2+. By means of a timed soaking, of the active area, with Cu2+ and Zn2+ diethyldithiocarbamates, the device can be driven through multiple conduction states, making it suitable for applications in artificial synapses research and memory storage systems.

AbstractSynthesis of a succession of new α‐aminophosphonates 4a‐j was achieved by the one‐pot three‐component Kabachnik‐Fields reaction by reacting equimolar quantities of 4‐morpholinoaniline (1), a variety of aromatic aldehydes 2a‐j and diethyl phosphite (3) using silica‐supported zinc bromide (ZnBr2‐SiO2) as a catalyst in solvent‐free conditions under microwave (MW) irradiation. Products 4a‐j were characterized by IR, 1H, 13C, 31P, NMR and mass spectral data. For these new set of compounds, two‐dimensional structures are drawn, three‐dimensional coordinates are generated and studied for their anti‐cancer activity against breast cancer. To support theoretical findings, experimental studies are performed using breast cancer cell lines. The results of these studies suggested that analogue, 4f has the maximum activity against breast cancer cells (MDA‐MB‐231). Since α‐aminophosphonates are less toxic compared to drugs currently available in the market, this new classes of drugs have very good potential for the treatment of Breast cancer.

AbstractThe CdS
WO3 nanocomposite was successfully synthesized using the hydrothermal method. The catalytic capacity of CdS
WO3 nanocomposite was evaluated based on various parameters, such as pH, catalyst load, bicarbonate and persulfate concentrations. The ratios of CdS to WO3 was also examined to acquire the photocatalytic performance in addition, the by–products and pathway were also studied. The findings showed that CdS
WO3 (ratio 3:7) produced better photodegradation performance in comparison to CdS
WO3 (ratio 1:1). Also, from the same investigation, the CdS
WO3 nanocomposite exhibited a slightly higher catalytic ability in the presence of 150 mg L–1 S2O82– ions (at pH 3) than with bicarbonate ions. A 40% degradation was observed in the presence of 150 mg L–1 S2O82– ions (at pH 3). Moreover, about 38% of adsorption was observed with bicarbonate ions. In this study, we systematically reveal the underlying mechanism of the improved photoactivity of CdS–WO3 nanocomposite using a hybrid density functional theory calculation. The interfacial interaction led to the formation of a built–in internal electric field at the CdS–WO3 interface to promote the separation of charge carriers, The theoretical results rationalise the experimental findings and offer a new understanding of the underlying mechanism of the photoactivity of CdS–WO3 nanocomposite. The degradation pathway of Ethylparaben, which involved dealkylation of ethyl unit was proposed.

AbstractInorganic luminescent materials as one of the important high‐performance materials are widely used for industry and scientific research, mainly owing to their outstanding luminescence properties. However, inorganic luminescent materials are typically brittle and inelastic, which greatly limit their use in practical applications, particularly in flexible optoelectronic devices. In this work, it is shown that “plum‐pudding” like CsPbBr3/Cs4PbBr6 perovskite crystals anchor onto Al2O3‐La2O3 (CCAL) nanofibrous membranes, which are synthesized via a facile electrospinning and subsequent supersaturated recrystallization process. The as‐synthesized CCAL membranes exhibit outstanding mechanical flexibility and luminescence properties. Meanwhile, the crystal structure and luminous performance of the CCAL membranes are regulated by different molar ratios of CsBr/PbBr2. The photoluminescence reaches a maximum value for the CCAL membranes produced with a CsBr/PbBr2 ratio of 1, and shows a narrow emission line‐width of 18 nm. Furthermore, the potential applications of the CCAL nanofibrous membranes in green light devices through a remote nanofibrous membranes packaging approach are demonstrated. A pure green emission is achieved with the Commission Internationale de L'Eclairage color coordinates of (0.28, 0.65). This facile strategy would open a new avenue to flexible inorganic luminescent materials for the lighting and backlight display industries.

AbstractOrganic luminescent materials with the ability to reversibly switch the luminescence when subjected to external stimuli have attracted considerable interest in recent years. However, the examples of luminescent materials that exhibit multiresponsive properties are rarely reported. In this work, a new stimuli‐responsive dye P1 is designed and synthesized with two identical chromophores of naphthalimide, one at each side of an amidoamine‐based spacer. This amide‐rich molecule offers many possibilities for forming intra‐ and intermolecular hydrogen bond interactions. Particularly, P1 has an intrinsic property of cocrystallizing with methanol. Compared with the pristine P1 sample, the as‐prepared two‐component cocrystalline material displays an exceptive deep‐blue emission, which is extremely rare among naphthalimide‐based molecules in the solid state. Furthermore, the target material exhibits an obvious mechanochromic fluorescent behavior and a large spectral shift under force stimuli. On the other hand, the cocrystalline material shows an unusual “turn off” thermochromic luminescence accompanied by solvent evaporation. Moreover, using external stimuli to reversibly manipulate fluorescent quantum yields is rarely reported to date. The results demonstrate the feasibility of a new design strategy for solid‐state luminescence switching materials: the incorporation of solvents into organic compounds by cocrystallization to obtain a crystalline state luminescence system.

Published: September 2018

AbstractFor mechanically protective coatings, the coating material usually requires sufficient stiffness and strength to resist external forces and meanwhile matched mechanical properties with the underneath substrate to maintain the structural integrity. These requirements generate a conflict that limits the coatings from achieving simultaneous surface properties (e.g., high wear‐resistance) and coating/substrate interfacial durability. Herein this conflict is circumvented by developing a new manufacturing technique for functional gradient coatings (FGCs) with the material composition and mechanical properties gradually varying crossing the coating thickness. The FGC is realized by controlling the spatial distribution of magnetic‐responsive nanoreinforcements inside a polymer matrix through a magnetic actuation process. By concentrating the reinforcements with hybrid sizes at the surface region and continuously diminishing toward the coating/substrate interface, the FGC is demonstrated to exhibit simultaneously high surface hardness, stiffness, and wear‐resistance, as well as superb interfacial durability that outperforms the homogeneous counterparts over an order of magnitude. The concept of FGC represents a mechanically optimized strategy in achieving maximal performances with minimal use and site‐specific distribution of the reinforcements, in accordance with the design principles of many load‐bearing biological materials. The presented manufacturing technique for gradient nanocomposites can be extended to develop various bioinspired heterogeneous materials with desired mechanical performances.

AbstractA template‐free all‐aqueous bulk preparation of robust hollow capsules having a gelatin shell from all‐in‐water double emulsions is reported. The hot (>40 °C) quaternary system water/polyethylene glycol (PEG)/gelatin/alginate is shown to spontaneously form PEG‐in‐gelatin‐in‐PEG double water emulsion droplets having a multinuclear core. These droplets are stable upon cooling below the temperature at which gelatin gelled. In contrast, above the melting temperature of gelatin, multinuclear double emulsion droplets controllably evolve into stable mononuclear yolk (aqueous PEG)‐shell (gelatin) capsules dispersed in the aqueous PEG continuous phase. It is demonstrated that the gelatin shell can accommodate negatively charged latex beads and be re‐enforced by glutaraldehyde or silica. These capsules are also shown to encapsulate payloads, suggesting possible applications in microencapsulation, drug delivery, and synthetic biology.
Multicriteria decision aid for agile methods evaluation using fuzzy PROMETHEE
Authors: El Beggar Omar 
Published: September 2018

AbstractThe last decade is marked by the blossom of agile methods and their growing use in many IT projects. They shared common principles and values, such as customer collaboration, early and continuous delivery of releases, accept requirements changing, and other common principles advocated by the agile manifesto since 2001. Meanwhile, there are significant differences among the practices adopted by the agile methods to fulfill agility's principles and values. The differences could be interpreted in terms of how an agile method judges the relative importance of such principles or its orientation to a specific project viewpoint (organizational, technical, or conceptual) rather than others. This fact leads to a necessity of a deep evaluation of agile methods to choose the best‐fit method suited for a project. Moreover, vague and uncertain information used to evaluate those lightweight methodologies could represent an additional difficulty for decision makers (DM). To drawback this problem, the multiple criteria decision aid (MCDA) method fuzzy PROMETHEE is proposed to assess agile methods with regard to different conflicting criteria and handling besides uncertainty in decision making. Furthermore, a sensitivity analysis is provided to validate results and verify their stability.

Published: September 2018

SummaryContinuous integration (CI) is a software development practice that has been gaining increasing popularity in the last few years. However, we still miss a collection of experiences regarding how software developers perceive the idea of CI, in terms of its fundamental concepts, the reasons that motivate the adoption of this practice, the reasons for build breakage, and the benefits and problems related to CI. To shed light on this direction, we conducted a user survey with 158 CI users. Through a mostly qualitative investigation, we produce a list of findings that are not always obvious. For instance, we observed that (1) developers are not sure whether a job failure represents a failure or not; (2) inadequate testing is the most common technical reason related to build breakage, whereas lack of time plays a role on the social reasons; and (3) although some respondents reported that CI systems increase the confidence that the code is in a known state, some respondents also reported that there is a false sense of confidence when blindly trusting tests. This empirical study is particularly relevant to those interested in better understanding and fostering CI practices either in an open‐source or industrial setting.

Published: September 2018

AbstractElectrochemical energy storage via Li‐ion batteries has changed modern life drastically and has enabled technologies such as portable electronic devices, electric vehicles and stationary grid storage. However, with the steadfast technological evolution and increasing energy demands, batteries need to be constantly improved to meet the needs of our society. Furthermore, increasing concerns are raised regarding sustainability, availability of raw materials and cost. Therefore, extensive research efforts have been focused on the development of new battery types leading to the emergence of the Na‐ion technology and the discovery of a myriad of new materials. In this context, polyanions became a prominent alternative to layered oxides. A large variety of polyanionic frameworks has been studied in the past years including phosphates, silicates and borates, but it was especially sulfates, which attracted a lot of attention due to their elevated operating voltages. The here presented article gives an overview of the exhaustive research on sulfate‐based cathode materials for Li‐ and Na‐ion batteries discussing recent findings and future perspectives.
