Relative Importance of Vital Rates to Population Dynamics of Wood Ducks
Authors: Hepp Gary R. , Gitzen Robert A. , Kennamer Robert A. 
Published: November 2019

ABSTRACTThe wood duck (Aix sponsa) is a common and important cavity‐nesting duck in North America; however, we know very little about how changes in vital rates influence population growth rate (λ). We used estimates of fertility and survival of female wood ducks from our nest‐box studies in South Carolina, Alabama, and Georgia, USA, to create a stage‐based matrix population model. We conducted perturbation analyses and ranked elasticity values to examine the relative importance of 17 component vital rates to λ. Female survival is influenced by nest success, so we recognized this female heterogeneity in our analyses. Four vital rates showed the greatest importance to λ. Analytic elasticities were greatest for breeding season and nonbreeding season survival of females that nested successfully, followed by nest success and female recruitment to the breeding population. Differences in female quality were important to λ. Next, we used process variation of vital rates and conducted life‐stage simulation analyses (LSA) followed by variance decomposition to determine the amount of variation in λ explained by each vital rate. Female recruitment to the breeding population explained 57.7% of the variation in λ followed by nest success (11.4%), and breeding and nonbreeding season survival of females that nested successfully (9.3% and 9.4%, respectively). Together these 4 vital rates explained 88% of the variation in λ. Mean asymptotic population growth rate (λ = 0.80 ± 0.08 [SD]) from LSA revealed a declining population. Recruitment of females hatched from nest boxes was insufficient to sustain the nest‐box population. However, including yearling (SY) females that were produced outside of nest boxes (i.e., immigrants) increased recruitment rates 1.5 to 2 times more than when only SY females recruited from nest boxes were included. Future research that examines how emigration and immigration interact with survival and reproduction to influence local population dynamics of wood ducks will be important for identifying the value of nest‐box programs to wood duck conservation and management. © 2019 The Wildlife Society.
Multicriteria decision making for sustainable development: A systematic review
Authors: Kandakoglu Ahmet , Frini Anissa , Ben Amor Sarah 
Published: November 2019

AbstractMaking decisions by integrating social and environmental concerns beyond the financial dimension involves complex decision‐making processes in which innovative approaches and best practices need to be implemented. Recently, the literature on decision‐making related to sustainable development has grown rapidly, and multiple criteria decision making or analysis (MCDM/A) methods appear to be the most widely used approaches. The general objective of this paper is to provide a systematic review of the literature on the use of MCDM/A in a sustainable development context. We carefully analysed 343 papers dealing with decision‐making in sustainable development contexts published in the last 7 years (2010‐2017) using MCDM/A methods. Descriptive statistics were provided to highlight the main trends and gaps in the literature, and future research avenues were presented. The results show that although sustainable development strives to achieve a balance between the short and the long term, most articles surveyed did not investigate either the long‐term perspective related to sustainable development or the unforeseen events that could impact future project evaluations. Indeed, the need for temporal MCDM/A methods under uncertainty emerges as an important research challenge. In addition, results show that the social dimension was the most frequently ignored dimension. In future research, decision‐making processes should closely investigate social well‐being and encourage the participation of stakeholders (including the communities affected). Finally, the recent research on sustainability is relatively easy to implement but may not lead to the desired outcome. Future research needs to develop methods that promote sustainability without being overly difficult to implement in practice.

Authors: Taylor Claire , Wiseman Theresa 
Published: November 2019

AbstractAimTo evaluate a new nurse consultant (NC) role, four specific objectives were set including examining the NC’s contribution to the local implementation over a 30‐month time period of the Recovery Package and assessing changes at a patient/professional/system level.MethodsAn evaluative process was agreed using Donabedian's (2005) model for measuring the quality of care provided. It focused on the NC’s contribution to the Trust's LWBC agenda including a review of Recovery Package metrics, analysis of the NC template recording activity across different domains, 360‐degree feedback and personal reflections.ResultsThe evaluation demonstrated the NC’s influence on individual patient care with an increase in three of the four Recovery Package metrics to the Trust; improvements in delivery of services and a higher level of participation in activities aimed at raising awareness to LWBC at a regional and national level. Broader influences of this role were also evident.

Published: November 2019

AbstractWollastonite is a functional filler that has great potential to be used in thermoplastic composites, replacing more expensive reinforcement such as glass fiber. Wollastonite‐reinforced polymer composite materials have attracted the attentions from research field and industries due to their biocompatibility and reinforcing ability in polymers. Due to the relatively high aspect ratio and hardness, wollastonite is able to improve the tensile and flexural strength of polymer composites. Many researches have been conducted to determine various properties of wollastonite reinforced polymer composites such as mechanical, flammability, thermal, and tribological properties in order to explore their potential in various applications. This review will focus on mechanical properties of wollastonite reinforced thermoplastic composites. Overall, it can be concluded that the properties of wollastonite‐filled polymer composites are the function of filler content, adhesion interactions of wollastonite particles with polymer matrix, size and shape of wollastonite particles. Further research and development are needed to widen its application, and these include the use of nano‐size wollastonite which can be produced synthetically as functional filler in thermoplastics.
Hyperspectral assessment of plant responses to multi‐stress environments: Prospects for managing protected agrosystems
Authors: Cotrozzi Lorenzo , Couture John J. 
Published: November 2019

Societal Impact StatementAdvancements in our ability to rapidly detect plant responses to stress are necessary to improve crop management practices and meet the global challenge of food security. Using optical approaches to detect plant stress before symptoms become apparent has great potential, but these approaches lack testing in multiple‐stress environments and fail to fully exploit the data collected. Using hyperspectral data from lettuce, we show that optical measurements can provide growers with important stress‐related information to inform crop management practices. We suggest that integrating this technology into protected agrosystems, such as greenhouses, could greatly improve crop quality and yield.
Summary

Tools to detect and predict stress pre‐visually are essential to optimally manage agrosystems. Here, we investigated the capability of reflectance spectroscopy to characterize responses of asymptomatic crop leaves under multi‐stress conditions.

Full range (350–2,500 nm) reflectance measurements and traditional plant stress responses were collected on lettuce leaves under the combination of different supplemental light types and intensities, fertilization and salinity. Partial least‐squares discriminate analysis and regression modeling and spectral indices were employed to characterize plant responses to multiple stress conditions, both alone and in combination.

Spectral profiles (400–800 nm + 1,900–2,200 nm) of individuals grown under variable environments were statistically different (p < .05) for multiple combinations. Partial least‐squares discriminate analysis accurately classified the different single stressors well (accuracy: 0.76–0.91), but generated moderate accuracies (0.63–0.65) for two‐stress combinations, and low accuracy (0.33) for higher order stress combinations. Osmotic potential, and chlorophyll and phenol concentrations were well predicted by spectral data (validation R2: 0.70–0.84). Higher lettuce yield and quality was found under sodium light at high intensity (850 µmol m−2 s−1 photosynthetic active radiation), with high fertilization (150 ppm N) and no salinity.

Our findings highlight the utility and limitations of vegetation spectroscopy in a protected agrosystem. We suggest that integration of vegetation spectroscopy into intelligent and automated greenhouses and other protected systems could enhance management efficiency, as well as crop quality and yield.

Published: November 2019

AbstractBACKGROUNDMetyltetraprole is a novel quinol oxidation site of Complex III inhibitor (QoI) fungicide that inhibits mitochondrial electron transport at the Qo site of the cytochrome bc1 complex. Previous reports have demonstrated that it is also active against the QoI‐resistant (QoI‐R) isolates of Zymoseptoria tritici and Pyrenophora teres with the mutations G143A and F129L in their cytochrome b gene, respectively. Further studies on cross‐resistance between metyltetraprole and existing QoIs were performed using an increased number of isolates of Z. tritici, P. teres, Ramularia collo‐cygni, Pyrenophora tritici‐repentis, and several other plant pathogenic fungi.RESULTSDifferences in the EC50 values between the wild‐type and QoI‐R isolates with the mutations G143A or F129L were always smaller for metyltetraprole compared to those for the existing QoIs, and they were never greater than five in terms of resistance factor. The 2‐year field experiments showed that the metyltetraprole treatment did not increase the percentage of QoI‐R isolates likely to harbor the G143A mutation in a Z. tritici population.CONCLUSIONThe unique behavior of metyltetraprole against the existing QoI‐R isolates was confirmed for all tested pathogen species. Our results provide important information to establish a fungicide resistance management strategy using metyltetraprole in combination or alternation with other fungicides. © 2019 The Authors.

Published: November 2019

AbstractA mechanistic study of the Cp*Rh(III)‐catalyzed annulative coupling of benzimidates with 4‐acyl‐1‐sulfonyltriazoles by CH activation was performed using density functional M06 method. It was demonstrated that the active catalyst during the coupling process should be the cation [Cp*Rh(OAc)]+ rather than the neutral Cp*Rh(OAc)2 and Zn(OAc)2 as proposed previously by the experimenters. A novel energetically feasible reaction pathway has been revealed theoretically in details. The acetic acid‐mediated cyclization process was confirmed to be the rate‐limiting step with an overall barrier of 24.3 kcal/mol, excluding any importance of the CH cleavage mechanism as supported by the kinetic isotope effect experiments. The major factors responsible for the preferred regioselectivity of N‐pyrimidinylinoles with 4‐acetyl‐1‐sulfonyltriazoles were discussed.
Secure distributed optimal frequency regulation of power grid with time‐varying voltages under cyberattack
Authors: Weng Shengxuan , Yue Dong , Dou Chunxia 
Published: November 2019

SummaryThe distributed optimal frequency regulation of power grid containing plenty of distributed renewable energy resources is highly dependent on the communication network. However, the utilization of a communication network makes the power grid vulnerable to cyberattacks, which could deteriorate the control performance and even cause the failure of a control task. To address this problem, this paper investigates the secure distributed optimal frequency regulation of power grid under cyberattack. The stealthy deceptive cyberattack model is constructed, and its perniciousness on optimal frequency regulation is analyzed. A novel type of secure distributed optimal frequency regulation is developed by introducing a secure‐based communication network to improve the resilience against cyberattack. It is proved theoretically that the secure regulation can restore the frequency deviation of each area to zero and minimize the total generation cost to retain the economic efficiency even under cyberattack. Simulation result shows the effectiveness of the proposed method.

AbstractTransportation has significantly boomed energy consumption and carbon dioxide (CO2) emissions. Understanding and forecasting the dynamic statuses of transportation CO2 emissions is a necessary step before making strategies to decrease CO2 emissions. Carbon Kuznets curve (CKC) hypothesis has been frequently validated properly to present the changing statuses of CO2 emissions in the literature. This study tests the CKC hypothesis using the data recording the CO2 emissions of transportation sectors of 119 countries over the period of 1995–2014, then turning points (TPs) are calculated for the countries where CKC hypothesis is turned out supported. Based on the CKC models, this study identifies different types of TPs, i.e. TP of carbon intensity (TPCI), TP of per capita CO2 emissions (TPPC), and TP of total CO2 emissions (TPTC) of the countries whose data support the CKC hypothesis. According to the earliness of the turning years (TYs) (TYCI, TYPC and TYTC) – the years when CO2 emissions peak – of individual countries, this study identified a step‐wise decoupling strategy for different countries, i.e. (1) first to reach the TPCI, (2) then to reach the TPPC, and (3) finally to reach the TPTC. As a result, the CKC hypothesis was supported by the data of 58 countries, among which, there are still seven countries having not reached any of the three TPs, 23 countries have reached the first‐step TP (TPCI), 9 countries have reached the second‐step TP (TPPC), and 19 countries have reached the third‐step TP (TPTC).

Published: November 2019

AbstractA novel silica‐based fluorescent sensor, (S‐DPP), was prepared via grafting of dimethyl 3,3′‐(propylazanediyl)(1Z,1′Z)‐bis(N‐(9H‐fluoren‐2‐yl)propanimidate) (DPP), onto the pore walls of SBA‐15 channels. DPP was prepared by growing of dendrimer (G= 0.5) onto the amino functionalized surface of SBA‐15, followed by anchoring of 2‐aminflourene via imine condensation. Synthesized materials were characterized using FT‐IR, PXRD, SEM, TEM, BET and TGA techniques. Fluorescence properties of the sensor were investigated in aqueous solution towards various metal ions. The signal quenching of sensor at λ=380 nm is based on complex formation between the S‐DPP and Fe3+ or Hg2+ ions, leading to the inhibition of reverse intramolecular charge transitions at the probe and appearance of new transitions at Mn+—S‐DPP complex. Furthermore, the limit of detection of both ions were calculated as 2.4 × 10−8 M and 6.3 × 10−8 M, respectively. A reversibility in fluorescence behavior of the probe was found in the presence of Cl−, and was demonstrated a circuit logic system with the Fe3+, Hg2+ and Cl− ions. Finally, density functional theory (DFT) and time‐dependent density functional theory (TDDFT) computational studies were performed in order to obtain a detailed electronic description of the quenching mechanism by Hg2+ and Fe3+ as well as studying the structure and bonding in the complexes.

Published: November 2019

AbstractA rapid response/recovery ribbon‐like hydroxyapatite (HAp) humidity sensor with loose spatial structure has been fabricated in this work. The HAp film was prepared on polyethylene terephthalate‐indium tin oxide (PET‐ITO) interdigital substrate by electrochemical deposition method. The HAp film was characterized by XRD, SEM, FTIR techniques. Electrochemically deposited HAp has a preferred orientation in a‐plane, which exposes a great many of hydroxyl groups. The HAp has a flat ribbon‐like microstructure that effectively captures and detects water molecules. The gap of the interdigital electrode was filled with long ribbon‐like HAp to form a loose spatial structure which facilitates water molecules adsorption and desorption. The HAp humidity sensor showed high sensitivity, low hysteresis and good linearity. In particular, HAp sensor has a short response time of 0.9 s and recovery time of 5.6 s. Besides, the humidity sensing mechanism of HAp sensor was also investigated in detail.

AbstractSince the environmental pollution posed by widely used sulfonamide antibiotics has been reported in natural aquatic system, designing novel adsorbents with excellent behaviors for adsorptive removal of sulfonamide antibiotics becomes a critical challenge in remediation management. Herein, two three‐component hybrid covalent organic polymers were successfully developed through a facile room‐temperature solution‐suspension method based on dynamic covalent Schiff‐base chemistry and used to remove a typical sulfonamide antibiotic [sulfadiazine (SDZ)] from aqueous solution. The 1,3,5‐triformylphloroglucinol (TFP) and benzene‐1,3,5‐tricarbohydrazide (BTCH) reacted with benzidine (BD) (JLUE‐COP‐26) and exhibited a good adsorption capacity for SDZ, followed by the reaction of TFP, BTCH and p‐phenylenediamine (PDA) (JLUE‐COP‐25). Moreover, the adsorption data of SDZ by two JLUE‐COPs were analyzed to be pseudo‐second‐order kinetic representable and Langmuir adsorption model fitted. In addition, the possible underlying mechanisms were proposed as a combination of porous feature, electrostatic force, hydrophobic interaction, π‐π stacking and hydrogen bonding interaction.

AbstractThree novel hydroxyl substituted and triphenylamine sidearm coumarin decorated molecules were prepared to examine the effect of adjacent hydroxyl substituent as well as coumarin units on the photophysical linear and nonlinear optical properties. Both hydroxyl function adjacent to the phenyl ring and extra coumarin unit is attributed to the red shifted absorption (435‐487 nm) and emission (496‐578 nm) compared to the plain triphenylamine based coumarin derivatives. Positive solvatochromism around 70 nm was observed in solvents with different polarity polarities and it is reinforced by solvent polarity plots and multilinear regression study. Very high viscosity induced emission enhancement (5.7 – 8.2 fold) was observed for in ethanol/polyethylene glycol‐400 system, highlighting their capability to act as efficient fluorescent molecular rotors (FMRs). The nonlinear optical properties were investigated by solvatochromism as well as a computational method using B3LYP 6–311++G (d, p) basis set. All these compounds exhibited large magnitudes of first order (65‐208x10 −30e.s.u) and second order (560‐2120x10 −36e.s.u) hyperpolarizability.
Designing of Ferromagnetic 3D Hierarchical Core‐Shell Fe3O4@NiO/Co3O4 Microspheres Derived from a MOF Precursor: As an Efficient Catalyst for C‐P Cross Coupling Reaction
Authors: Mohammadinezhad Arezou , Akhlaghinia Batool 
Published: November 2019

AbstractHerein, we report the synthesis of a 3D hierarchical heterostructure microsphere through a facile solvothermal and hydrothermal method followed by an annealing treatment. The obtained ternary core‐shell nanostructured was comprehensively characterized by means of variety techniques including FT‐IR, XRD, BET, TEM, FE‐SEM, EDX, EDX‐mapping, VSM and ICP‐OES. It was found that this hierarchical nanostructured could promote the C−P cross coupling reaction of a large library of functional substrates. Benefiting from the unique hierarchical architecture and the synergistic effect among multiple components resulted from the coexistence of micro‐, meso‐ and macropores as well as its small nano‐crystallite size (20‐71 nm), this novel catalyst revealed superior catalytic performance in the C−P cross coupling reaction. More importantly, the ferromagnetic behavior of 3D hierarchical core‐shell Fe3O4@NiO/Co3O4 microspheres is responsible for easy separation from the reaction mixture using an external magnetic field and its long term‐durability under reaction conditions even after nine consecutive recycle runs.
