An analytical continuum model for axially loaded end‐bearing piles in inhomogeneous soil
Authors: Anoyatis George , Mylonakis George , Tsikas Aggelos 
Published: January 2019

SummaryAn approximate static solution is derived for the elastic settlement and load‐transfer mechanism in axially loaded end‐bearing piles in inhomogeneous soil obeying a power law variation in shear modulus with depth. The proposed generalised formulation can handle different types of soil inhomogeneity by employing pertinent eigenexpansions of the dependent variables over the vertical coordinate, in the form of static soil “modes”, analogous to those used in structural dynamics. Contrary to available models for homogeneous soil, the associated Fourier coefficients are coupled, obtained as solutions to a set of simultaneous algebraic equations of equal rank to the number of modes considered. Closed‐form solutions are derived for the (1) pile head stiffness; (2) pile settlement, axial stress, and side friction profiles leading to actual, depth‐dependent Winkler moduli, (3) displacement and stress fields in the soil; and (4) average, depth‐independent Winkler moduli to match pile head settlement. The predictive power of the model is verified via comparisons against finite element analyses. The applicability to inhomogeneous soil of an existing regression formula for the average Winkler modulus is explored.
School psychology interns’ characterizations of family–school partnerships
Authors: Soutullo Olivia R. , Sanders‐Smith Stephanie C. , Smith‐Bonahue Tina M. 
Published: January 2019

AbstractSchool psychologists are encouraged to establish family–school partnerships with culturally and linguistically diverse families across the spectrum of child development. Partnerships and collaborations have been described in prior literature as bidirectional, nonhierarchical relationships between families and schools, expanding on the more traditional but limited concept of unidirectional parent involvement in school. This qualitative study describes five specialist‐level school psychology interns’ experiences facilitating family–school partnerships with culturally diverse families during their internship year. Findings focus on defining and identifying characteristics of family–school partnerships from interns’ recollections of their lived experiences. Five salient elements characterized the practical experience of a partnership: requisite situations for partnering, stakeholder involvement, intern's actions, intern's emotional responses, and the outcome or quality of the family–school partnership. These findings have implications for the training of school psychologists and the ways that family–school interactions are conceptualized both in training programs and in school settings.

Published: January 2019

AbstractObjectiveEmerging evidence demonstrates the positive health benefits of light physical activity (LPA) for cancer survivors. Yet, little research has explored modifiable factors that facilitate or hinder LPA behavior in this population. Correlates of LPA among cancer survivors were examined, and stratified by moderate‐to‐vigorous physical activity (MVPA) status.MethodsA cross‐sectional analysis using the American Cancer Society's Studies of Cancer Survivors‐I (N = 1751) was conducted. Correlates of interest were health‐care provider support for physical activity, perceived health competence, perceived social support, unsupportive partner behaviors, and perceived susceptibility to cancer recurrence. The primary outcome was self‐reported LPA categorized at 0, 1‐59, 60‐119, and 120+ minutes per week. Multivariable ordinal regressions using forced entry were conducted, stratified by MVPA status.ResultsAdjusted multivariable models revealed that, among those reporting no MVPA (n = 757), greater provider support for physical activity (adjusted odds ratio [aOR] = 1.51; 95% CI, 1.05‐2.17; P = 0.03), greater perceived health competence (aOR = 1.44; 95% CI, 1.10‐1.88; P = 0.01), and greater unsupportive partner behaviors (aOR = 1.06; 95% CI, 1.01‐1.12; P = 0.03) were significantly correlated with higher LPA. No social cognitive constructs were correlated with LPA among those already engaging in MVPA (n = 994).ConclusionsLPA interventions targeting cancer survivors not engaging in any MVPA are warranted and may optimize limited intervention resources. Furthermore, interventions may be more efficacious by applying behavior change techniques that incorporate health‐care provider support and improves health competence and positive interpersonal skills.

AbstractBACKGROUNDHypothenemus hampei Ferrari (Coleoptera: Curculionidae) is the main pest of coffee due to the damage caused to coffee berries. Effective management methods and prevention of insecticide resistance are urgently needed against this insect. Bioassays were conducted to assess the effects of the diamide insecticide cyantraniliprole on H. hampei. Cyantraniliprole is the most recent compound registered against this species after the phasing out of endosulfan, the main insecticide historically used against the coffee borer for the past 30 years. Toxicity, survival, progeny production, respiration rate, and behavioral responses to cyantraniliprole were evaluated.RESULTSCyantraniliprole was toxic to adult H. hampei (LC50 = 0.67 mg mL−1 and LC90 = 1.71 mg mL−1). Adult survival was 95% without exposure to cyantraniliprole, decreasing to 52% in insects exposed to LC50 cyantraniliprole and 27% in insects treated with LC90 cyantraniliprole. Furthermore, H. hampei showed reduced mobility on insecticide‐treated surfaces. The insecticide also led to a decrease in the respiration rate of H. hampei for up to 3 h after exposure, altering behavioral responses and locomotor activity.CONCLUSIONCyantraniliprole exhibits lethal and sublethal effects on H. hampei and can be used in rotation in integrated pest management programs for control of this species in coffee cultivation systems. © 2019 Society of Chemical Industry

AbstractIn this work, the preparation of bis‐[(3‐aminopropyl)triethoxysilane]dichloride immobilized on magnetic nano γ‐Fe2O3@SiO2 is reported. This reagent can be obtained via the reaction of two molecules of 3‐aminopropyl)triethoxysilane with 1,4‐dichlorobutane followed by immobilization of the resulted di‐cationic compound on silica coated nano γ‐Fe2O3. After characterization using FT‐IR, XRD, FE‐SEM and TGA techniques, the prepared reagent was used as a highly efficient catalyst for the promotion of the synthesis of pyrano[2,3‐d]pyrimidinones (thiones) and pyrido[2,3‐d]pyrimidine derivatives. The rates and especially the yields of the reactions were excellent in comparison to the reported catalyst for these reactions. Also, the recovery and reusability of the catalyst were excellent for both of the reactions using an external magnet.

AbstractGraphene oxide immobilized Cu(II) Schiff base complex, GO@AF‐SB−Cu, was synthesized by the reaction of a Schiff base functionalized Graphene oxide, GO@AF‐SB, with Cu(OAc)2.H2O in ethanol under reflux. The immobilized complex was isolated as a black‐coloured solid and characterized by various physico‐chemical techniques, such as Fourier transform infrared spectroscopy (FT‐IR), Fourier transform Raman spectroscopy (FT‐Raman), Powder X‐ray diffraction (PXRD), X‐ray photoelectron spectroscopy (XPS), Field emission scanning electron microscopy (FESEM), Energy dispersive X‐ray microscopy (EDX), Elemental mapping, Inductively coupled plasma atomic emission spectroscopy (ICP‐AES) and Thermo gravimetric analysis (TGA). The catalytic activity of the complex was explored in Chan‐Lam coupling reaction of amines and arylboronic acids without using any co‐catalyst or oxidant. Further, the catalyst could be easily recovered quantitatively from the reaction mixture by simple filtration and reused up to five times without significant loss in the catalytic activity. All the isolated organic products were characterized by 1H and 13C NMR spectroscopy.

AbstractAn ICT‐based mitochondria‐targeted fluorescent probe Mito‐NP was designed and synthesized for the detection of H2O2, with radical fluorescence intensity changes (up to 120‐fold) and a large Stokes shift (93 nm) in aqueous solution. There was good linear relationship (R2=0.9983) between the concentration of H2O2 in the range of 0 to 100 μM and the fluorescence intensity at 553 nm, with a low detection limit of 0.25 μM (S/N=3). Mito‐NP could also visualize enzymatically generated H2O2. Furthermore, the probe could detect endogenous H2O2 with good mitochondria targeting ability in living cells and could also detect the change in H2O2 levels during mitochondria‐oriented apoptosis.Introduction

Published: January 2019

AbstractAn improved and rapid green synthesis of N‐alkyl/aryl piperazine hydrochlorides using synergistic coupling of hydrated Task Specific Ionic Liquid ([BbIm]OH) and Microwave Irradiation (MWI) has been described. The protocol worked well with good yields for electron withdrawing as well as electron donating groups in aryl amines to provide the respective aryl piperazine hydrochlorides. Presence of other labile groups like hydroxyl and thiol in the aryl amines remained unaffected. The said TSIL could be reused upto five cycles without an appreciable loss of the catalytic activity. It is proposed that [BbIm]OH along with a water molecule is able to catalyse the reaction due to symphoria. The proposed mechanism is supported by DFT and molecular dynamics studies. The use of hydrated TSIL like ([BbIm]OH) as reaction media may open new gates in green organic syntheses.

Published: January 2019

AbstractWe investigated the applicability of an ionic liquid electrolyte to a phosphorus‐doped Si (P‐doped Si) electrode to improve the performance and safety of the lithium‐ion battery. The electrode exhibited excellent cycling performance with a discharge capacity of 1000 mA h g−1 over 1400 cycles in the ionic liquid electrolyte, whereas the capacity decayed at the 170th cycle in the organic electrolyte. The lithiation/delithiation reaction of P‐doped Si occurred a localized region in the organic electrolyte, which generated a high stress and large strain. The strain accumulated under repeated charge‐discharge cycling, leading to severe electrode disintegration. In contrast, the reaction of P‐doped Si proceeded uniformly in the ionic liquid electrolyte, which suppressed the electrode disintegration. The P‐doped Si electrode also showed good rate performance in the ionic liquid electrolyte; a discharge capacity of 1000 mA h g−1 was retained at 10 C.

Published: January 2019

AbstractThe donor‐acceptor orbital interaction between the unoccupied orbital of Li+ and the lone pair of oxygen atoms in the carbonyl group of Li+‐carbonate complexes shows significant decrease on fluorination. This has been investigated through molecular orbital formalism based density functional theory. The fluorination process lowers the binding energy (reduced up to 13.8 kcal/mol), and widens the HOMO‐LUMO gap (enhanced up to 0.7 eV), which is essential for achieving electrolytes with high potential window in Li‐ion battery. Furthermore, the impact of fluorination on few critical factors has been observed, i. e. dipole moment (drastic enhancement), IR spectra (most affected C=O vibrational mode shows blue shift in the spectra) and Raman active mode (carbonyl group stretching mode doublet (
) shifted to higher frequency) which have been probed by vibrational frequency analysis.

Published: January 2019

AbstractSn‐based materials, one of the most promising alternatives, hold higher theoretical capacity (994 mA h g−1) than traditional graphite anodes and attract great attention in lithium‐ion batteries (LIBs). In this work, an in‐situ formed sodium chloride (NaCl) is employed as the template to support the formation of a three‐dimensional (3D) hierarchical porous carbon skeleton. The 3D porous materials, which specific surface area reach 221.1 m2/g, can shorten the ions transport path and increase the contact between the electrode and the electrolyte. Meanwhile, the Sn nanoparticles are restricted in the carbon matrix, which can effectively enhance the conductivity and solve some major problems of the volume fluctuation, particle aggregation and electrode pulverization. Consequently, the 3D porous carbon skeleton/Sn (3D‐PCSS) composites exhibit a high capacity (1046.7 mA h g−1 at 50 mA g−1 after 60 cycles), long cycle life (490 mA h g−1 after 600 cycles at 1000 mA g−1) and excellent rate performance. Moreover, a new method to improve energy storage properties in LIBs will be involved‐confining Sn nanoparticles in hierarchically porous 3D carbon skeleton.

Published: January 2019

AbstractHalide perovskites in general and organometal‐halide perovskites in particular have become an intensely researched topic due their excellent optical properties, cheap production costs, and easy fabrication procedures. A high absorption coefficient, paired with a direct bandgap and a wide variety of accessible deposition method, makes these perovskites an excellent materials class for use in a plethora of applications, ranging from solar cells to light‐emitting diodes, and image sensors with architectures of varying length scales ranging from simple thin‐film solid‐state solar cells to highly ordered nanostructured solar cells and sensors. A downside of perovskites is their poor stability when subjected to ambient conditions as a consequence of poor encapsulation which, can be countered by using a nanostructured as additional encapsulation. In this work, different approaches to fabricate nanostructured perovskite‐based light harvesting devices are outlined and the influences of nanostructuring on the performance and stability of the incorporated perovskites are discussed, as well as future research perspectives being highlighted.

Published: January 2019

AbstractLack of quality analytical methods with assured robustness and reliability has always been a serious concern for drug regulatory agencies. In the present study, a contemporary approach of analytical life‐cycle management resulted in the robust and reliable chromatographic analysis of lacidipine at a retention time of 5.1 min on a C‐18 column. Method variables such as %acetonitrile, flow rate, and pH were optimized using the design of experiment approach and their effect on critical quality attributes was studied. The attributes of the present study were significantly influenced by %acetonitrile and flow of the mobile phase. The newly optimized method was validated for various parameters with values in accordance with federal guidance. The lifecycle approach proved to be beneficial for routine application with a potential of future bio‐analytical utility.

Abstract
Endothelial cells play a central role in physiological function and pathophysiology of blood vessels in health and disease. However, the molecular mechanism that establishes the endothelial phenotype, and contributes to its signature cell type-specific gene expression, is not yet understood. We studied the regulation of a highly endothelial-specific gene, von Willebrand factor (VWF), in induced pluripotent stem cells generated from primary endothelial cells (human umbilical vein endothelial cells [HUVEC] into a pluripotent state [HiPS]) and subsequently differentiated back into endothelial cells. This allowed us to explore how VWF expression is regulated when the endothelial phenotype is revoked (endothelial cells to HiPS), and re-established (HiPS back to endothelial cells [EC-Diff]). HiPS were generated from HUVECs, their pluripotency established, and then differentiated back to endothelial cells. We established phenotypic characteristics and robust angiogenic function of EC-Diff. Gene array analyses, VWF chromatin modifications, and transacting factors binding assays were performed on the three cell types (HUVEC, HiPS, and EC-Diff). The results demonstrated that generally cohorts of transacting factors that function as transcriptional activators, and those that contribute to histone acetylation and DNA demethylation, were significantly decreased in HiPS compared with HUVECs and EC-Diff. In contrast, there were significant increases in the gene expression levels of epigenetic modifiers that function as methyl transferases in HiPS compared with endothelial cells. The results demonstrated that alterations in chromatin modifications of the VWF gene, in addition to expression and binding of transacting factors that specifically function as activators, are responsible for establishing endothelial specific regulation of the VWF gene.
