Solubilization of Multiwall Carbon Nanotubes by 3‐Aminopropyltriethoxysilane Towards the Fabrication of Electrochemical Biosensors with Promoted Electron Transfer

A simple procedure has been described for the fabrication of multi-wall carbon nanotube (CNT) based electrochemical sensors. 3-Aminopropyltriethoxysilane (APTES) induced solubilization of CNTs allowed for the modification of electrode surfaces. With glucose oxidase (GOx), a flavin (FAD) containing enzyme as a model system, APTES was used as a solubilizing agent for CNTs as well as an immobilization matrix for GOx to construct a mediatorless biosensor. Our biosensor was able to efficiently monitor direct electroactivity of GOx at the electrode surface. A well-defined glucose response was observed at −0.45 V (vs. Ag/AgCl) whereas relevant physiological levels (0.1 mM) of three common interfering species, uric acid, ascorbic acid, and acetaminophen, resulted in no response. Although CNTs modified by APTES acted as semiconductors to reduce the exposed sensing surface, we reasoned nanoscale “dendrites” of CNTs modified by APTES formed a network and projected outwards from the electrode surface and acted like bundled ultra-microelectrodes that allowed access to the active FAD site and facilitated direct electron transfer to the immobilized enzyme. The glucose biosensor prepared using a carbon fiber (11 μm) exhibited picoamperometric current response within 5 s with detection limits of 5–10 μM.
Comparison of cecal microbiota composition in a three-way cross model in two hybrid pigs

30 Objectives: The intestinal microbiota plays an important role in host physiology, metabolism, 31 immunity, and behavior. And host genetics could influence the gut microbiota of hybrid 32 animals. The three-way cross model is commonly utilized in commercial pig production; 33 however, the effects of this model on the gut microbial composition are rarely reported. 34 Methods: Two three-way hybrid pigs were selected, with Saba pigs as the starting maternal 35 pig: Duroc × (Berkshire × Saba) (DBS) pig, Berkshire × (Duroc × Saba) (BDS) pig. One 36 hundred pigs of each model were reared from 35 days (d) to 210 d. The body weight or feed 37 consumption of all pigs were recorded and their feed/gain (F/G) ratio was calculated. On day 38 210, 10 pigs were selected for slaughter, and cecal chyme samples were collected for 16S 39 rRNA gene sequencing. 40 Results: The final body weight (FBW) and average daily gain (ADG) of DBS pigs were 41 significantly higher than those of BDS pigs (p<0.05), while the F/G ratios of DBS pigs were 42 significantly lower than those of BDS pigs (p<0.05). The dominant phyla in DBS and BDS 43 pigs were Bacteroidetes (55.23% vs 59%, respectively) and Firmicutes (36.65% vs 34.86%, 44 respectively) (p>0.05). At the genus level, the abundance of Prevotella, Roseburia, and 45 Anaerovibrio in DBS pigs was significantly lower than in BDS pigs (p<0.01). The abundance 46 of Eubacterium, Clostridium XI, Bacteroides, Methanomassiliicoccus, and Parabacteroides in 47 DBS pigs was significantly higher than in BDS pigs (p<0.05). The FBWs and ADGs were 48 positively correlated with Bacteroides, ClostridiumXI, and Parabacteroides but negatively 49 correlated with the Prevotella, Prevotella/Bacteroides (P/B) ratio, Roseburia, and 50 Anaerovibrio. 51 Ac ce pt ed A rti cle
Effects of systemically administered abaloparatide, an osteoanabolic PTHrP analog, as an adjuvant therapy for spinal fusion in rats

Abaloparatide is a parathyroid hormone receptor agonist that increases bone formation and reduces vertebral and nonvertebral fracture risk in women with postmenopausal osteoporosis. Animal studies indicate abaloparatide stimulates vertebral bone formation and enhances bony bridging and biomechanical stability of fracture calluses.
Emphasis on unsteady dynamics of bioconvective hybrid nanofluid flow over an upward–downward moving rotating disk

The fluid flow between the rotating disk has wide range of applications and are used in medical equipment's, car brake system, gas turbines, manufacturing of glass and plastic films. Inspired from these applications, we scrutinized the behavior of an axisymmetric expansion–contraction rotating disk on three‐dimensional flow of hybrid nanoparticles in the presence of microorganisms. Here, we considered copper and silica nanoparticles suspended in base fluid water. It is known that, the inequality of concentration in chemically reactive species affecting mass transfer mechanism and activation energy plays an important role in increasing the production speed of chemical reactions. Hence, the Arrhenius activation energy and chemical reaction effects are added in the mass equation. Autorelated transformations were adopted to reduce PDE's to ODE's and then, we utilized the RKF‐45 by adopting shooting skill to solve reduced ODE's. The analysis of rate of heat and mass transfer is done through graphs. Furthermore, change in velocity, thermal and concentration profiles for various nondimensional parameters are deliberated briefly by using suitable plots. Result reveals that rise in wall expansion/contraction parameter supports up the velocity gradients, higher the values of bioconvection Peclet number and concentration difference parameter declines the microorganism profile and Nusselt number decreases for rise in values of thermophoresis parameter.
Waste to Catalyst: Synthesis of Catalysts from Sewage Sludge of the Mining, Steel, and Petroleum Industries

The generation of sewage sludge presents a problem for several manufacturing companies as it results from industrial processes or effluent treatment systems. The treatment of this type of waste requires high economic investment, for this reason, it is necessary to find alternatives to recover the valuable materials of the sludges. In this study, metal catalysts were synthesized using waste sludge from the steel, mining, and hydrocarbon industries. The waste sludge was subjected to thermal treatments for the removal of organic content and the reduction of metals with hydrogen current to activate their catalytic properties. The sludge and synthesized catalysts were analyzed to determine their physical, chemical, thermoenergetic, and catalytic properties. Catalytic activity was evaluated using CO chemisorption and by thermal–catalytic decomposition of crude oil. The best conditions for synthesizing the catalysts were a calcination temperature between 300 and 500 °C and a reduction temperature between 300 and 900 °C. The catalysts presented a specific surface between 2.33 and 16.78 m2/g. The catalytic material had a heat capacity between 0.7 and 1.2 kJ/kg∙K. The synthesized materials presented catalytic activity comparable to that of commercial catalysts. With this recovery technique, the industrial waste can be valorized, obtaining catalyst derived from the sludges and promoting the circular economy of manufacturing companies.
Mechanically tough double-network hydrogels with high electronic conductivity

New, mechanically tough, and electro-conductive double-network hydrogels (E-DN gels) were synthesised by oxidative polymerisation of 3,4-ethylenedioxythiophene in ethanol in the presence of a double-network hydrogel (DN gel) matrix composed of poly(styrenesulphonic acid) as the first network and poly(N,N-dimethyl acrylamide) as the second network. The E-DN gels showed not only excellent mechanical performance, with a Young's modulus of 3 MPa and a fracture stress of 2 MPa, but also electrical conductivity of the order of 1 S cm−1 in both dry and water-swollen states. Scanning electron and atomic force microscopy observations showed that electro-conductive poly(3,4-ethylenedioxythiophene) (PEDOT) particles with diameters of several hundred nanometres uniformly filled the interior of E-DN gels. The AC impedance analysis clearly indicated that the E-DN hydrogels were simple resistors that became charge carriers as a result of PEDOT doping. Even when the E-DN gels were swollen and had high water content, the electrical conductivity resulted from electronic carrier transport.
Research on spatial resilience characteristics and response mechanism of Chengdu-Chongqing urban agglomeration based on power-law

Urban agglomeration is the spatial organization form of urban development and the main carrier of population, economy and information gathering to promote regional coordinated development. Therefore, it is important to research the sustainable development of urban agglomeration. Focus on the scientific issue of the relationship between power-law distribution structure of spatial elements and spatial resilience of urban agglomeration; using the number of urban permanent population and urban built-up area size as the key spatial elements of Chengdu-Chongqing urban agglomeration, firstly, we discussed the spatial-temporal evolution law of power-law characteristics of key spatial elements of Chengdu-Chongqing urban agglomeration. Secondly, we revealed the response mechanism of spatial resilience to power-law distribution of key spatial elements of Chengdu-Chongqing urban agglomeration. The conclusions as following: (1) The spatial resilience of Chengdu-Chongqing urban agglomeration characterized as “concentration” dominated by large cities. (2) The spatial resilience and Pareto distribution of Chengdu-Chongqing urban agglomeration have a remarkable and stable response relationship. (3) In order to maximize the spatial resilience of Chengdu-Chongqing urban agglomeration, it is urgent to control the number of urban permanent population and built-up area scale of large cities.
Electrospun tin oxide nanofibers

Ultrafine tin oxide (SnO2) fibers in the rutile structure, with diameters ranging from 60nm to several microns, were synthesized using electrospinning and metallorganic decomposition techniques. In this work we use a precursor solution which is a mixture of a pure SnO2 sol made from SnCl4 : H2O : C3H7OH : 2-C3H7OH at a molar ratio of 1:9:9:6, and a viscous solution made from poly(ethylene oxide) (PEO) (molecular weight 900,000) and chloroform CHCl3 at a ratio of 200mg PEO/10mL CHCl3. This solution allows obtaining an appropriate viscosity for the electrospinning process. The as deposited fibers were sintered at 400, 500, 600, 700 and 800°C in air for two hours. Previous results using this method and characterizing the fibers with scanning electron microscopy (SEM), x-ray diffraction (XRD), Raman microspectrometry and x-ray photoelectron spectroscopy (XPS) showed that up to the sintering temperature of 700°C, the synthesized fibers are composed of SnO2. Further analysis using SEM, Profilometry, Atomic Force Microscopy (SPM), Auger Spectroscopy and I/V analysis is presented in this paper. The results show that the fibers are composed of tin oxide and that smooth and continuous fibers in different shapes (straight, curved, ribbon-like, and spring-like) can be obtained using this method. The change in resistivity as a function of the annealing temperature can be attributed to the thermally activated formation of a nearly stoichoimetric solid.
High-Quality Thermochemistry Data on Polycyclic Aromatic Hydrocarbons via Quantum Chemistry

In this article, recent work on calculating high-quality enthalpies of formation for polycyclic aromatic hydrocarbons (PAHs) based on both density functional theory (DFT) and Gaussian-3 (G3) model chemistry methods is discussed. It is shown that through the use of an empirical correction model, the systematic errors in low-level DFT calculations can be controlled to produce reliable thermochemistry. It is further shown that the G3 results have a more regular systematic error and as a consequence a simpler model may be used to correct for systematic deviations. It is seen that the resulting enthalpy of formation values are in good agreement with the available experimental data, and that the predictions are sufficiently robust to point out certain errors in experimental determinations. This work was done as part of a larger effort to create a curated data set of property data for a large set of PAH molecules. In furtherance of this goal, UV/Vis spectra have been computed using time-dependent DFT. The collection of PAH data is being made publicly available through a web-based database that is briefly described.
New insights into the mechanical pre-stressing of piezotransducers

Although pre-stressing is a requirement for the operation of a high-power piezo transducers, its impact on the model, the performance and the design of such devices is still not yet fully covered in the literature. This work attempts to bridge this gap by analyzing how the components of the Butterworth-Van Dyke model, the resonances, electrical impedances, electromechanical coupling factor, mechanical losses, and the tuning inductance are determined as a function of mechanical pre-stress. We have employed the Butterworth Van-Dyke model to study piezoelectric transducers tightened with a range of pre-stressing levels (12.2–60.1 MPa). As expected, the experimental results indicate that the components of the Butterworth-Van Dyke model are dependent upon the mechanical pre-stressing. The conclusions point out that, under mechanical pre-stressing levels between a threshold value and 60.1 MPa, the transducers used in this work tend to stabilize and enhance their performances. Also, upon stabilization, the transducers can be tuned with a constant inductance, which may also aid the design of ultrasonic systems. Overall, this work contributes to the definition of pre-stressing levels and its relationship with the length of the transducer, the mechanical losses, and the tuning.
What should be included in the criteria for compulsive sexual behavior disorder?

Abstract Compulsive sexual behavior disorder (CSBD) is currently defined in the eleventh revision of the International Classification of Diseases (ICD-11) as an impulse control disorder. Criteria for hypersexual disorder (HD) had been proposed in 2010 for the fifth revision of Diagnostic and Statistical Manual (DSM-5). In this article, we compare differences between HD and CSBD and discuss their relevance. Significant differences between HD and CSBD criteria include: (1) the role of sexual behavior as a maladaptive coping and emotion regulation strategy listed in criteria for HD but not in those for CSBD; (2) different exclusionary criteria including bipolar and substance use disorders in HD but not in CSBD, and (3) inclusion of new considerations in CSBD, such as moral incongruence (as an exclusion criterion), and diminished pleasure from sexual activity. Each of these aspects has clinical and research-related implications. The inclusion of CSBD in the ICD-11 will have a significant impact on clinical practice and research. Researchers should continue to investigate core and related features of CSBD, inlcuding those not included in the current criteria, in order to provide additional insight into the disorder and to help promote clinical advances.
Gas Chromatographic and Mass Spectrometric Identification of Tetrachloroalkanoic and Dichloroalkenoic Acids in Eel Lipids

Chlorinated fatty acid methyl esters, transesterified from the lipids of eel (Anguilla anguilla ; obtained from the receiving waters of a chlorine bleaching pulp mill), were studied by gas chromatography (GC) using electrolytic conductivity detection and mass spectrometry (MS) with electron impact and ammonia positive-ion chemical ionization. GC retention indices and column difference values in combination with GC/MS demonstrated the presence of isomers of methyl dichlorotetradecenoate, methyl dichlorohexadecenoate, methyl dichlorooctadecenoate and methyl tetrachlorotetradecanoate. Isomers of methyl threo, threo-tetrachlorooctadecanoate were identified by co-injection of the eel sample and synthesized reference compounds. The results were confirmed by ammonia positive-ion chemical ionization high-resolution selective-ion monitoring of the ammonium adduct molecular ions.
The Lexicon of Transitive Verbs of Motion and the Asymmetry Between Goal and Source PPs

The aim of this research is to verify the hypotheses on the asymmetry between source and goal PPs from both a syntactic and a cognitive point of view.Nam’s (2004) syntactic analysis shows that Goal PPs behave like adjuncts while Source PPs are internal arguments. Lakusta and Landau’s (2005) cognitive experimental research reveals the tendency in speakers to express Goal paths over Source paths. Landau (2010) suggests that one of the causes of this asymmetry might be related to the lexicon: are there more attachment verbs than detachment verbs? If so, the more frequent exposure to goal paths would explain the goal bias.For this purpose I have classified approximately 500 Italian transitive verbs of motion, the analysis of which revealed that verbs showing a goal pattern account for the vast majority in the lexicon, but also that goal verbs and source verbs behave differently with respect to such properties as transitive-intransitive pronominal alternation and subject alternation. The former is much more frequent with goal verbs, while the latter is applicable only to goal verbs.Furthermore, the application of diagnostics like topicalization and pro-form confirms the syntactic asymmetry between source and goal PPs.
Investigation and forecast of Sudden Stratospheric Warming events with chemistry climate model SOCOL

To achieve better agreement of simulated Arctic winter stratospheric dynamic with observations assimilation procedure nudging was incorporated in CCM SOCOL. Trajectories based on SOCOL output winds demonstrate the reasonable agreement with trajectories based on reanalysis data inside the polar vortex and can be used for analysis and forecast of ozone related processes in winter-spring seasons. Obtained results of several recent major Arctic SSW events analysis show that CCM SOCOL could be used for SSW forecast over the period up to 8 days.
Inherited Platelet Function Disorder From Novel Mutations in RAS Guanyl-Releasing Protein-2 Confirmed by Sanger Sequencing

Inherited platelet disorders (IPDs) are genetically heterogeneous rare disorders due to quantitative and/or qualitative abnormalities of the platelet. IPDs are often predisposed to significant medical complications. RAS guanyl-releasing protein-2 (RASGRP2) was recently identified as a gene affected in patients with platelet function defects and a bleeding complication. RASGRP2 codes for the protein CalDAG-GEFI RAS (guanyl-releasing protein-2), a guanine nucleotide exchange factor for small guanosine triphosphate(GTP)ase Rap1. We used Sanger sequencing to identify a novel function-disrupting homozygous mutation in RASGRP2 responsible for bleeding diathesis and platelet dysfunction in a patient.
Piezoelectric Energy Harvesting Prediction and Efficient Management for Industrial Wireless Sensor

The vibrations, due to their abundance in most industrial processes, constitute an attractive solution for the power supply of Industrial Wireless Sensor (IWS). However, the amount of energy that can be harvested presents numerous fluctuations due to the engines’ different operating modes (overload, full load, or even operation without charge). Most designs do not incorporate this fluctuation in the definition of the specifications of the autonomous IWS. This paper then presents a design method to ensure the node’s energy autonomy while maximizing its Quality of Service (QoS). To precisely define the specifications of the IWS, vibration measurements were carried out at its location for one month. The recorded data was used to propose a new Predictor of the Harvestable Energy from Vibrations (PHEV). A comparative evaluation of the proposed PHEV performances with a state-of-the-art predictor is carried out. The results obtained show that the PHEV makes it possible to minimize the Root Mean Square Error (RMSE) from 28.63 mW to 19.52 mW. A model of energy dissipation in IWS, considering the Internet of Things’ requirements, was established. The model is based on Long-Range (LoRa)/Long-Range Communication Wide Area Network (LoRaWan). The amount of data transmitted is then maximized according to the expected energy harvest rate by setting up a Maximization Data Size Protocol (MDSP). The proposed method makes it possible to ensure an acceptable QoS without resorting to reconfigurable circuits, which are sometimes bulky for miniature devices such as the IWS.
Tourism-Induced Place Change: The Role of Place Attachment, Emotions, and Tourism Concern in Predicting Supportive or Oppositional Behavioral Responses

This study investigates residents’ emotional and behavioral responses to environmental changes caused by tourism development. Statistical analysis conducted on a comprehensive sample of 1,001 residents from Amsterdam, the Netherlands, explores emotional responses as an underlying mechanism used to explain residents’ behavioral responses as well as their tourism concern as boundary conditions for this mediating effect. In contributing to the extant debate on the role of place attachment (i.e., the bond between people and their environment) in predicting residents’ supportive behavior for tourism development, the findings reveal that high levels of place attachment generally result in oppositional behavior. Moreover, results confirm that emotions, as evoked by tourism-induced place change, explain residents’ supportive and oppositional responses. Positive emotional responses to tourism decrease the likelihood of residents’ oppositional behavior. High levels of tourism concern diminish the positive influence of place attachment on positive emotions.
A hybrid kinematic controller for resilient obstacle avoidance of autonomous ships

Resilience is an important feature of autonomous systems. To be resilient, a control system must be stable, robust, and safe. This paper explores the use of hybrid feedback controllers to ensure robustness towards uncertainties and disturbances in motion control systems for autonomous ships. Motivated by recent developments in control barrier functions (CBFs) for safe maneuvering of autonomous ships, a CBF-based hybrid kinematic controller for obstacle avoidance is proposed. The controller uses course angle as control input, making it suitable for ships with a limited speed envelope. The performance of the controller is illustrated by simulations, using an underactuated ship as a case study.
