“It's my own fault”: Accounts and consequences of falling when living with rheumatoid arthritis
Authors: Graham Karly , Birt Linda , MacGregor Alexander , Watts Laura , Poland Fiona 
Published: August 2019

AbstractIntroductionRheumatoid arthritis (RA) leads to biomechanical joint changes, which increases the risk of falling. The consequence of falling may be physical injury. However, the psychological consequences, including the fear of falling, can be equally important.MethodsParticipants were recruited from a larger prospective study which explored the incidence of falls in people with RA. Purposive sampling considered age, sex, time since diagnosis and fall history. The recruitment site was a regional hospital. Data were collected from semi‐structured qualitative interviews and, after each fall, brief telephone interviews. Thematic analysis methods were used to investigate the psychological and social impact of falling in people with RA.ResultsTwelve participants were interviewed (aged 64–85, mean 74 years; six had fallen between one and 23 times, and six had no reported falls in last 12 months). Data were supplemented with telephone notes from 287 post‐fall telephone calls. Three themes were developed: (i) the falls imaginary illustrates that the fear of falling is not dependent on experience; (ii) agentic risk management reports on the ways people self‐manage and display resilience when at risk of falling; (iii) the absence of the health professional explores the ways in which people reported being unsupported by healthcare services.ConclusionFear of falling when living with RA is tangible in those who have and have not fallen. This fear may limit opportunities for full participation in life. However, some people display personal resourcefulness, continuing to live purposeful lives. Understanding personal responses to falling will support the development of community interventions specific to this high‐risk group.
Simplified three‐dimensional analysis of horizontally vibrating floating and fixed‐end pile groups
Authors: Luan Lubao , Zheng Changjie , Kouretzis George 
Published: August 2019

SummaryThis note presents an approximate analytical solution for estimating the time‐harmonic impedance of pile groups subjected to horizontal dynamic loads, for different boundary conditions at pile tip (free and fixed). The derived solution considers waves due to pile vibrations propagating in both horizontal and vertical directions, unlike earlier solutions based on the plane‐strain model, which ignores vertically propagating waves. This allows accounting for pile boundary conditions on the soil attenuation function, as well as modeling the response of the pipe group‐soil system near the first natural frequency of the soil layer, where solutions based on the plane‐strain model fail to account for resonance phenomena.
Well siblings of children with chronic illness: A synthesis research study
Authors: Havill Nancy , Fleming Louise K. , Knafl Kathleen 
Published: August 2019

AbstractWell siblings of chronically ill children experience family disruptions that profoundly affect them. Previous research focusing on well siblings’ experiences has often produced inconsistent findings, likely the result of varying study designs and samples. The purposes of this synthesis research study were twofold: (a) to assess the applicability of existing grounded theory of sibling response to a child's cancer to a wider range of childhood conditions; and (b) to refine the existing theory to reflect the experiences of the broader sample. Data for the synthesis came from a National Institute of Nursing Research‐funded mixed‐methods synthesis examining the intersection of childhood chronic illness and family life. The current analysis was based on well sibling results extracted from 78 research reports published between 2000 and 2014. An existing grounded theory, Creating a Tenuous Balance (CTB), was discovered at the outset of analysis and used as the primary framework for coding and synthesizing results. The focus of most studies was siblings’ responses to 14 chronic conditions, with cancer being the most often studied. Results reflected siblings’ perspectives of their experiences as well as perspectives of parents and the ill child. The analysis substantiated all four patterns of sibling behavior included in CTB, with the patterns of adapting to changes in personal and family life, and handling strong emotions being especially challenging aspects of the sibling experience. Moreover, the results expanded several aspects of CTB. The analysis provided evidence of the applicability of the theory to a varied group of chronic conditions and enabled us to identify important areas for developing interventions to support siblings.
Resilient distributed model predictive control for energy management of interconnected microgrids
Authors: Ananduta Wicak , Maestre José María , Ocampo‐Martinez Carlos , Ishii Hideaki 
Published: August 2019

SummaryDistributed energy management of interconnected microgrids that is based on model predictive control (MPC) relies on the cooperation of all agents (microgrids). This paper discusses the case in which some of the agents might perform one type of adversarial actions (attacks) and they do not comply with the decisions computed by performing a distributed MPC algorithm. In this regard, these agents could obtain a better performance at the cost of degrading the performance of the network as a whole. A resilient distributed method that can deal with such issues is proposed in this paper. The method consists of two parts. The first part is to ensure that the decisions obtained from the algorithm are robustly feasible against most of the attacks with high confidence. In this part, we formulate the economic dispatch problem, taking into account the attacks as a chance‐constrained problem, and employ a two‐step randomization‐based approach to obtain a feasible solution with a predefined level of confidence. The second part consists in the identification and mitigation of the adversarial agents, which utilizes hypothesis testing with Bayesian inference and requires each agent to solve a mixed‐integer problem to decide the connections with its neighbors. In addition, an analysis of the decisions computed using the stochastic approach and the outcome of the identification and mitigation method is provided. The performance of the proposed approach is also shown through numerical simulations.

Authors: Punia Sonu , Kulandaivelan Sivachidambaram 
Published: August 2019

AbstractObjectiveThe aim of this study is to confirm whether 8 weeks of home‐based isometric handgrip (IHG) training would reduce resting blood pressure (RBP) in an adult Indian population.MethodologyHypertensive patients (Stage 1 [previously prehypertension] and Stage 2 [previously Stage 1 hypertension]) aged 30–45 years, male and female, were included. Intervention: Two groups were included (active control group and IHG training group at 30% of maximal voluntary isometric contraction). Outcomes of this study were resting pulse rate (PR) and RBP, which were taken at baseline and after 8 weeks. Stratified randomization was done by sex and hypertension grade. The study was a double‐blind intervention (both participants and the assessor were blinded to intervention allotment).ResultsForty hypertensive individuals were randomly assigned to a control (N = 20) and an 8‐week home‐based IHG training (N = 20) using a stratified random sampling technique. Each training session consisted of 4 × 2 min bouts with a 4‐min rest between bouts for 8 weeks. Resting PR and RBP were taken at baseline and after 8 weeks. After 8 weeks, there was a significant reduction in blood pressure and PR values in the IHG group as compared with those in the control group: systolic blood pressure (mean difference, MD −8.75 mmHg; 95% CI [−6.51, −10.39]); diastolic blood pressure (MD −8.35 mmHg; 95% CI [−6.25, −10.45]); mean arterial pressure (MD −8.13 mmHg; 95% CI [−6.21, −10.05]); and PR (MD −8.90 mmHg; 95% CI [−5.08, −12.72].ConclusionOn the basis of study findings, home‐based IHG training can be used as an adjunct to control BP in the initial stage of hypertension in an Indian population.
Evaluation of Scymnus nubilus (Coleoptera: Coccinellidae) as a biological control agent against Aphis spiraecola and Cinara juniperi (Hemiptera: Aphididae)

AbstractBACKGROUNDAphids are a major insect pest of forestry systems. In this study, we evaluate the potential of the ladybeetle Scymnus nubilus Mulsant (Coleoptera: Coccinellidae) as a biological control agent against Aphis spiraecola Patch and Cinara juniperi (De Geer) (Hemiptera: Aphididae) infesting Azorean endemic plants reared in forestry nurseries.RESULTSAphis spiraecola, infesting Viburnum treleasei Gand. (Dipsacales: Adroxaceae), was the most abundant aphid; however, a higher proportion of Juniperus brevifolia (Seub.) Antoine (Pinales: Cupressaceae) was infested by C. juniperi. Scymnus nubilus fourth instar larvae were able to complete development on both aphid species. Voracity was significantly higher when S. nubilus was fed on A. spiraecola but biomass consumption was significantly lower. The relative growth rate and conversion efficiency of the fourth instar larvae were similar. Field experiments indicated that S. nubilus can contribute to the decrease in pest population densities. However, the fourth instar larvae proved to be more efficient when released onto A. spiraecola; this outcome can be attributed to the distribution patterns of the aphids on the host plant and to the aphid or host plant morphology. Predator density and sleeve cage effect are apparently critical factors in reaching an efficient control.CONCLUSIONThe obtained results provide the essential preliminary information required to establish future programs of biological control against aphids infesting Azorean endemic plants. Developmental and feeding performances, as well as the immediate impact of the predator when released onto A. spiraecola colonies, indicate that S. nubilus could be a useful candidate for reducing aphid populations. © 2019 Society of Chemical Industry

AbstractThe implementation of bioeconomy is important in seeking to achieve the Sustainable Development Goals. Thus, in recent years, more attention is focused on sustainable bioeconomy. Referring to weak and strong sustainability approaches, many authors stated that bioeconomy is related only to weak sustainability, but this study provides a framework for policy makers that allows the definition and implementation of the bioeconomy based on the strong sustainability approach. Furthermore, researchers evaluating bioeconomy implementation conventionally encompassed the economic, social, and environmental dimensions of the impact of bio‐products; however, they did not consider the strong sustainability approach. Strong sustainability additionally requires not crossing ecological thresholds and, thus, implies consideration of planetary boundaries. Therefore, the inclusion of land footprint and biocapacity measures in the bioeconomy strategy, verifying that the land footprint does not exceed the level of biocapacity, is essential for the creation of a strongly sustainable bioeconomy. This study embarks on the definition of the bioeconomy based on strong sustainability and contributes to the discussion about bioeconomy implementation in the context of sustainable development.

Published: August 2019

AbstractWe prepare defective carbon nanosheets (DCNS) that is obtained by chemical activation of Syzygium cumini leaves and employ them as electrode materials for electrochemical supercapacitors. DCNS exhibits large specific surface area (ca. 1184.4 m2/g), electrical conductivity of ca. 1.23 × 10‐2 S/cm, moderate level of structural defects of ca. 0.72, and sufficient oxygen‐containing functional groups as well. It leads to induce huge electroactive sites, which correspond to high specific capacitance of ca. 222.26 F/g with a better durability. The low‐cost, eco‐friendly, and electroactive carbon materials could play an important role for its applications in energy‐storage devices such as batteries.

AbstractA new bent‐core liquid crystal (LC) compound CPDB derived from a 4‐chlororesorcinol central core unit with two terephthalate based rod‐like units carrying chiral (S)‐3,7‐dimethyloctyloxy terminal chains has been synthesized and LC / modified γ‐Al2O3 nanocomposites have been prepared in different compositions. The effects of being doped with 0.3, 0.5, 1.0, 2.0, 3.0 and 4.0% modified γ‐Al2O3 nanoparticles on mesomorphic properties of the new bent‐core liquid crystal, which shows an enantiotropic SmA phase, were investigated by differential scanning calorimetry and optical polarizing microscopy. The surface of γ‐Al2O3 nanoparticles was modified with a cationic agent, cetyltrimethyl ammonium bromide (CTAB), used as a compatibilizer for providing interaction of liquid crystal molecule with alumina nanoparticles. The immobilization of CTAB on γ‐Al2O3 nanoparticle surface via physical adsorption in solution was confirmed by TGA and preserved of crystalline structure of aluminium oxide was proved by XRD analysis. The presence and homogeneous distribution of alumina nanoparticles in LC were confirmed by using Scanning Electron Microscopy (SEM) and energy dispersive X‐ray (EDX) spectroscopy. The modified γ‐Al2O3 nanoparticles in CPDB liquid crystal give rise to a slight increase in the mesomorphic range by preserving mesophase type as observed in pure liquid crystalline compound.

AbstractResolution of resources and environmental crises requires an efficient separation technologies, consequently, scientists and engineers are working vigorously for ideal separation materials. Laminar graphene oxide (GO) is a two‐dimensional (2D) material offers considerable interest in this field due to its single atomic layer thickness, good stability, chemical inertness, and variety of functional groups. Recently, GO have emerged as a novel membrane material for molecular and ionic separation of gases, solvent, water, and desalination applications. This tutorial review aims to discuss the various approaches used to control the stacking of GO‐based membrane with emphasis of advantages and drawbacks associated with each approach. Further, attention will also be given to describe the recent progress in GO based membranes for ionic and molecular separations. Meanwhile, challenges and opportunities will also be discussed in detail. We hope this review expected to provide a compact source of information that will be of great interest to chemists, material scientists, physicists, and engineers working or planning to work in GO based membranes for separation applications.

Published: August 2019

AbstractThe Andean bear alopecia syndrome is a progressive and chronic condition documented in ex situ populations. Recent advances focus on treating symptoms, not preventing future cases. We therefore explored the epidemiology of this syndrome through an analysis of husbandry and veterinary conditions of 63 Andean bears (26M:37F) housed in North and South American zoos and other ex situ circumstances. We had the most complete information for the North American population and found that 29% of females (n = 24) were affected. No males (n = 26) were affected. An analysis of generalized linear models indicated that three models were competitive in describing the occurrence of the condition (i.e., ΔAICc  ≤ 2): the model including only the individual's sex (χ2 = 13.41, df = 1, p < .001), the model including both individual sex and social housing status (χ2 = 1.36, df = 2, p < .001), and the model including both individual sex and the expression of stereotypical behaviors (χ2 = 13.82, df = 2, p = .001). Stereotypical behaviors were common among both males (50%, n = 26) and females (51.9%, n = 27) whether or not they were affected, but the syndrome was seen only in females who had been socially housed. Therefore, we suggest that the Andean bear alopecia syndrome is a symptomatic response to the long‐term social housing of bears that would otherwise not live socially. To prevent new cases, we recommend that female Andean bears be housed with adult conspecifics only when females choose to cohabitate.

AbstractBackgroundHepatectomy remains an important curative treatment for hepatocellular carcinoma (HCC). Intermittent Pringle maneuver (IPM) is commonly applied during hepatectomy for control of bleeding. Whether the ischemia/reperfusion injury brought by IPM adversely affects the operative outcomes is controversial. This study aims to examine whether the application of IPM during hepatectomy affects the long‐term outcomes.MethodsTwo randomized controlled trials (RCT) have been carried out previously to evaluate the short‐term outcomes of IPM. The present study represented a post hoc analysis on the HCC patients from the first RCT and all patients from the second RCT, and the long‐term outcomes were evaluated.ResultsThere were 88 patients each in the IPM group and the no‐Pringle‐maneuver (NPM) group. The patient demographics, type and extent of liver resection and histopathological findings were comparable between the two groups. The 1‐, 3‐, 5‐year overall survival in the IPM and NPM groups was 92.0%, 82.0%, 72.1% and 93.2%, 68.8%, 58.1%, respectively (P = 0.030). The 1‐, 3‐, 5‐year disease‐free survival in the IPM and NPM groups was 73.6%, 56.2%, 49.7% and 71.6%, 49.4%, 40.3%, respectively (P = 0.366). On multivariable analysis, IPM was a favorable factor for overall survival (P = 0.035). Subgroup analysis showed that a clamp time of 16–30 min (P = 0.024) and cirrhotic patients with IPM (P = 0.009) had better overall survival.ConclusionIPM provided a better overall survival after hepatectomy for patients with HCC. Such survival benefit was noted in cirrhotic patients, and the beneficial duration of clamp was 16–30 min.Trial registrationNCT00730743 and NCT01759901 (http://www.clinicaltrials.gov).
