Published: October 2020

AbstractBackgroundIt was reported that intravenous amiodarone might induce ventricular fibrillation for acute treatment in patients with atrial fibrillation (AF) and Wolff‐Parkinson‐White (WPW) syndrome. No study was done to assess its application comprehensively in this population.MethodsThis study was a retrospective analysis and undertaken by reviewing medical records and electronic databases to search for patients admitted with tachycardia resulting from WPW syndrome and AF, who have intravenously administrated amiodarone at the emergency department from January 2008 to June 2018.ResultsThirty patients were involved in this study, of which 27 were males. The mean age of the patients was 47.8 ± 17.0 years. The mean systolic blood pressure and diastolic blood pressure were 111.9 ± 18.3 mmHg and 76.1 ± 14.6 mmHg, respectively. The mean heart rate was 171 (150‐189) beats per minute. Half of the patients (53.3%) had no comorbidities, and only one had prior syncope. Nearly 17 patients (56.7%) started with a loading dose of 150 mg. No ventricular acceleration or VF developed. The incidence of hypotension was 3.3% (1/30). Eighteen patients (60.0%) restored to sinus rhythm by amiodarone with the conversion time of 486.0 (229.0‐1278.0) minutes.ConclusionsIntravenous amiodarone might be an alternative for acute treatment of AF and WPW syndrome in patients characterized by stable hemodynamics, relatively low admission heart rate, few comorbidities, elder age, and no prior syncope. The loading dosage of 150 mg appeared to be preferred, and the maintenance period was better to less than 12 hours. Monitoring and electrolyte correction were also necessary. It is essential to keep a defibrillator nearby during pharmacologic cardioversion.
A micro‐process model of institutional complexity in public hybrid organizations: Construal of identity threats and mitigation strategies
Authors: Shams Farshid 
Published: October 2020

AbstractThis article analyses how non‐managerial professionals in public service organizations experience the tension between managerial and professional institutional logics and manage to minimize it through identity work. By studying how academics in ten Canadian public universities talk about their routine work activities, it is found that they interpret the institutional contradictions between these logics as threats to their identities and mitigate them by undertaking discursive strategies to author legitimate selves. Three mitigation strategies of delegitimization, selective identification and appropriation of realized publicness are identified. These findings are synthesized in a process model of construal and response that illustrates a set of micro‐practices of professionals by which the institutional hybridity is maintained. By moving beyond professionals' resistance and hybridization (integrating the two logics) and identifying a recursive relational positioning mechanism as a way of coping with institutional complexity, this study complements previous findings in the growing literature on organizing professionalism.

AbstractBackgroundHematopoietic stem cell transplantation (HSCT) can cure chronic granulomatous disease (CGD), but it remains debated whether all conventionally treated CGD patients benefit from HSCT.MethodsWe retrospectively analyzed 104 conventionally treated CGD patients, of whom 50 patients underwent HSCT.ResultsOn conventional treatment, seven patients (13%) died after a median time of 16.2 years (interquartile range [IQR] 7.0‐18.0). Survival without severe complications was 10 ± 3% (mean ± SD) at the age of 20 years; 85% of patients developed at least one infection, 76% one non‐infectious inflammation. After HSCT, 44 patients (88%) were alive at a median follow‐up of 2.3 years (IQR 0.8‐4.9): Six patients (12%) died from infections. Survival after HSCT was significantly better for patients transplanted ≤8 years (96 ± 4%) or for patients without active complications at HSCT (100%). Eight patients suffered from graft failure (16%); six (12%) developed acute graft‐vs‐host disease requiring systemic treatment. Conventionally treated patients developed events that required medical attention at a median frequency of 1.7 (IQR 0.8‐3.2) events per year vs 0 (IQR 0.0‐0.5) in patients beyond the first year post‐HSCT. While most conventionally treated CGD patients failed to thrive, catch‐up growth after HSCT in surviving patients reached the individual percentiles at the age of diagnosis of CGD.ConclusionChronic granulomatous disease patients undergoing HSCT until 8 years of age show excellent survival, but young children need more intense conditioning to avoid graft rejection. Risks and benefits of HSCT for adolescents and adults must still be weighed carefully.

Published: October 2020

ObjectiveTo describe the prevalence of malnutrition risk and pain in older hospital patients and characterise the association between these two problems.Research methods and proceduresThe study includes a secondary data analysis of data collected in two cross‐sectional studies. Data collection was performed in 2017 and 2018 using a standardised and tested questionnaire. The study protocol was approved by an ethical committee.ResultsData from 3406 patients were analysed. Among the participants, 24.6% of the patients were at risk of malnutrition, and 59.6% of the patients reported feeling pain. A significantly higher number of patients with pain (26.4%) were at risk of malnutrition than patients without pain (22.1%). The multivariate logistic regression analysis showed that patients with severe/very severe or unbearable pain were 1.439 times more likely to develop a risk of malnutrition than patients without pain. Patients with cancer or diseases of the digestive system were twice as likely to develop malnutrition than those without these diseases.ConclusionsThe results of this study show that older patients with severe pain are at higher risk of developing a risk of malnutrition than those without pain, although the study design (cross‐sectional) does not imply causality. Therefore, special efforts should be made to assess pain in these patients to reduce the negative consequences of this pain, such as malnutrition.
Mixed carbonate–siliciclastic tidal sedimentation in the Miocene to Pliocene Bouse Formation, palaeo‐Gulf of California

Published: October 2020

AbstractMixed carbonate–siliciclastic deposits provide unique insights into hydrodynamic processes that control sedimentation in tidal systems. This study presents sedimentological and ichnological data from the upper Miocene to lower Pliocene Bouse Formation, which accumulated during regional transgression at the margin of a tidal strait near the north end of the ancestral Gulf of California. The basal carbonate member of the Bouse Formation records deposition in a tide‐influenced, compositionally mixed carbonate–siliciclastic system dominated by salt marsh, tidal flat and channel environments. The basal carbonate member is an overall deepening up succession of facies associations comprising: Facies Association 1 – siliciclastic‐rich heterolithic facies, lime mudstone with desiccation cracks, and plant debris rich carbonate silt interpreted as siliciclastic‐rich tidal flats; Facies Association 2 – well‐sorted gravels, siliciclastic‐rich sandy strata, lime mudstone with desiccation cracks, and sandy microbial micrite interpreted as tidal‐channel deposits; Facies Association 3 – carbonate‐rich heterolithic lime mudstone to well‐sorted, cross‐bedded bioclastic grainstone interpreted as intertidal to shallow subtidal deposits; and Facies Association 4 – lime mudstone interpreted as shallow to deep subtidal low‐energy deposits that record the end of tidal conditions in the basin. Trace fossils include marine forms Gyrolithes, Teichichnus and Thalassinoides, and non‐diagnostic forms Arenicolites, Cochlichnus, Conichnus, Lockeia, Planolites, Skolithos and Treptichnus (known from marine, brackish and freshwater environments). The diminutive size of trace fossils reflects brackish conditions created by mixing of freshwater and seawater. This study provides evidence for a late Miocene to early Pliocene humid climate in south‐western North America, in stark contrast to the modern hyperarid climate. Factors that controlled the relative percentage of mixed carbonate and siliciclastic sediment include siliciclastic input from local rivers, in situ carbonate production, current energy, degree of tidal mixing and relative sea level. Pronounced facies variability at bedform, outcrop and basin scale documented in this study appears to be an important characteristic of mixed carbonate–siliciclastic deposits in tidal depositional systems.
The role of sediment gravity flows on the morphological development of a large submarine canyon (Taiwan Canyon), north‐east South China Sea

Published: October 2020

AbstractHigh‐resolution multibeam bathymetric and multichannel seismic data are used to investigate the morphology of a submarine canyon (Taiwan Canyon), and its surrounding strata, in the north‐east South China Sea. This submarine canyon shows two main branches at its head, and changes its orientation from north‐west/south‐east to east–west due to the effect of a tectonically active seamount. The asymmetry of the submarine canyon’s banks in its middle reach is due to the combined action of recurrent slope instability and turbidity currents. In addition, two fields of sediment waves were identified in the study area. Field 1 is located on the south‐west levée of the canyon and is fed by turbidity currents from one of its branches, being also associated with marked hydraulic jumps. Field 2 is observed in the southern bank of the lower canyon reach and was formed by the overspill of turbidity currents within the Taiwan Canyon due to the effect of inertial centrifugal forces. Turbidity currents sourced from Dongsha Channel also contributed to forming Field 2. Importantly, trains of plunge pools have been identified along the thalweg of the lower canyon reach, generated by turbidity currents deriving from the submarine canyons in the north of the Taiwan Canyon. These results not only provide a very detailed account of submarine bedforms within and around a large submarine canyon, but also contribute to a better understanding of their origin and development. The high‐resolution bathymetric and seismic data in this work reveal how gravity flows can drive erosion and deposition in submarine canyons.
Assessing and Explaining the Diverging Trajectories of Territorial Parties and Politics in Italy and Spain (2008‐2018)
Authors: Vampa Davide , Gray Caroline 
Published: October 2020

AbstractUntil the mid‐2000s, territorial politics played a considerable role in both Italy and Spain. Two regionalist parties, among others, clearly contributed to this: Democratic Convergence of Catalonia (CDC) and the Northern League. Yet evidence shows that the two parties, while starting from relatively similar positions, have followed diverging trajectories, particularly after the financial (and then economic) crisis that hit their respective countries. CDC pushed its pro‐autonomy stances to the extreme and eventually ended up supporting Catalan independence. On the other hand, the League dropped its regionalist agenda and even became a state‐wide party. By comparing these two cases, this article aims to shed light on the mechanisms that lead to the radicalisation or moderation (and even abandonment) of regionalist parties’ territorial demands. These opposite movements have broader implications, since they have been accompanied by increasing polarisation of territorial politics in Spain and the de‐politicisation of this issue in Italy.
Experimental Investigation of Pressure Drop Characteristics of Viscous Fluid Flow Through Small Diameter Orifices

Published: October 2020

Abstract
An experimental study on the flow of a highly viscous fluid through small diameter orifices was conducted. Pressure drops were measured for each of nine orifices, including orifices of nominal diameter 0.5, 1, and 3 mm and three different orifice thicknesses, over wide ranges of flow rates and temperatures. The fluid under consideration exhibits steep dependence of the properties (changes of several orders of magnitude) as a function of temperature and pressure and is also non-Newtonian at the lower temperatures. At small values of Reynolds number, an increase in aspect ratio (length/diameter ratio of the orifice) causes an increase in Euler number. It was also found that at extremely low Reynolds numbers, the Euler number was very strongly influenced by the Reynolds number, while the dependence becomes weaker as the Reynolds number increases toward the turbulent regime, and the Euler number tends to assume a constant value determined by the aspect ratio and the diameter ratio. A two-region (based on Reynolds number) model was developed to predict Euler number as a function of diameter ratio, aspect ratio, viscosity ratio, and generalized Reynolds number. It is shown that for such a highly viscous fluid with some non-Newtonian behavior, accounting for the shear rate through the generalized Reynolds number results in a considerable improvement in the predictive capabilities of the model. Over the laminar, transition, and turbulent regions, the model predicts 86% of the data within ±25% for the geometry and operating conditions investigated in this study.

Authors: Tian Hualing , Liu Zhonggang , Cai Yanjun , Su Zhi 
Published: October 2020

Abstract
Due to the high theoretical capacity, high platform voltage, stable structure, and mild conditions for synthesis, LiVOPO4 is expected to become the next generation of cathode materials for lithium-ion batteries (LIBs). However, due to the relatively weak ionic conductivity, its commercial application has been largely limited. The paper reported that acetylene black was used as the reducing agent and the pure phase nanostructured orthorhombic β-LiVOPO4 was obtained by carbothermal reduction method. A significant improvement in ionic conductivity was achieved, and the results were compared with previous studies, the initial discharge capacity of the material was considerably enhanced. The results show that the electrical conductivity and the initial discharge capacity of the material were also significantly improved. The sample obtained by holding at 600 °C for 10 h exhibited a maximum discharge capacity of 141.4 mAh g−1 between 3 V and 4.5 V at 0.05 C, with a value of 136.3 mAh g−1, retained after 50 cycles. This represents capacity retention of 96.39%.

Published: October 2020

Abstract
Engine experiments were performed for measurement of regulated, unregulated, and particulate emissions using a 2.2 L transportation compression ignition engine fueled with blends of diesel and biodiesels derived from Jatropha and waste cooking oils. JB20 (20% v/v Jatropha biodiesel blended with 80% v/v diesel), WCOB20 (20% v/v waste cooking oil biodiesel blended with 80% v/v diesel), and baseline mineral diesel were used as test fuels in this study. Experiments were performed at an engine speed of 2000 rpm at five engine loads (0%, 25%, 50%, 75%, and 100% rated load). Regulated emission results exhibited that JB20 and WCOB20 emitted higher hydrocarbons and carbon monoxide (CO) at low engine loads compared to baseline diesel, whereas WCOB20 exhibited relatively higher oxides of nitrogen (NOx) emissions compared to baseline diesel. Unregulated emissions were higher at low engine loads and decreased with increasing engine load. Biodiesel blends showed relatively higher methane and ethylene trace emissions compared to baseline diesel, whereas WCOB20 showed higher formaldehyde, formic acid, iso-pentane, sulfur dioxide, and n-octane emissions compared to diesel at no load. Particulate number concentrations were relatively higher from biodiesel blends compared to baseline diesel at most engine operating conditions.
Automated Keyword Filtering in Latent Dirichlet Allocation for Identifying Product Attributes From Online Reviews
Authors: Joung Junegak , Kim Harrison M. 
Published: October 2020

Abstract
Identifying product attributes from the perspective of a customer is essential to measure the satisfaction, importance, and Kano category of each product attribute for product design. This article proposes automated keyword filtering to identify product attributes from online customer reviews based on latent Dirichlet allocation. The preprocessing for latent Dirichlet allocation is important because it affects the results of topic modeling; however, previous research performed latent Dirichlet allocation either without removing noise keywords or by manually eliminating them. The proposed method improves the preprocessing for latent Dirichlet allocation by conducting automated filtering to remove the noise keywords that are not related to the product. A case study of Android smartphones is performed to validate the proposed method. The performance of the latent Dirichlet allocation by the proposed method is compared to that of a previous method, and according to the latent Dirichlet allocation results, the former exhibits a higher performance than the latter.

Published: October 2020

Abstract
To satisfy the increasing requirements of high-precision and zero-backlash transmission in the modern machine tools and industrial robots, a precision measurement method of roller enveloping hourglass worm tooth surface is demonstrated. The profile modification method of hourglass worm tooth surface is proposed for the zero-backlash meshing, and the mathematical model of standard theoretical tooth surface and actual modified tooth surface is established. The deviations of hourglass worm tooth surface are defined, and the measuring method is proposed based on the gear measuring center. The matching method of theoretical tooth surface and actual tooth surface is analyzed, through establishing the evaluation object function and designing the search iterative method. The roller enveloping hourglass worm sample is ground based on the profile modification principle, and the deviations on the tooth surface are measured by the proposed measurement method. The results turn out that this precision measurement method is feasible. This study is expected to give an evaluation standard to improve the tooth surface accuracy of roller enveloping hourglass worm.

Published: October 2020

Abstract
Buildings of the future are expected to not only be energy efficient but also able to offer grid services through implementation of demand-side management strategies by utilizing existing and new technologies that enhance electrical load flexibility. With the high penetration of variable renewables, grid operators have to balance between variable supply with controllable and adaptable demand. This article reviews the current literature on grid-interactive efficient buildings (GEBs) that can provide grid services. In particular, the review identifies categories and examples of measures and technologies that are suitable for GEBs using various criteria. These criteria include demand-side management strategies, potential to provide grid services, technology maturity, as well as ability to model the technologies to perform detailed analyses and assessments in whole-building simulation software.
Advanced Energy, Exergy, and Environmental (3E) Analyses and Optimization of a Coal-Fired 400 MW Thermal Power Plant
Authors: Hoseinzadeh Siamak , Stephan Heyns P. 
Published: October 2020

AbstractIn this article, energy, exergy, and environmental (3E) analysis of a 400 MW thermal power plant is investigated. First, the components of the power plant are examined in terms of energy consumption, and subsequently the energy losses, exergy destruction, and exergetic efficiency are obtained. It is shown that the highest energy losses are in the closed feedwater heaters Nos. 1 and 5 and the boiler with amounts of 7.6 × 10 J/s and 6.5 × 107 J/s, respectively. The highest exergy destruction occurs in the boiler and amounts to 4.13 × 108 J/s. The highest exergetic efficiency is 0.98 and is associated with the closed feedwater heaters Nos. 4 and 8. It is observed that the exergetic efficiency and exergy destruction in the boiler are the primarily affected by changes in the environmental temperature. Furthermore, by increasing the main pressure in the turbine, the load on the power plant is increased, and increasing the condenser pressure reduces the load on the power plant. In an environmental analysis, the production of pollutants such as SO2 production and CO2 emission has been investigated.
Coupled Mode Flutter Analysis of Turbomachinery Blades Using an Adaptation of the p–k Method
Authors: Schuff Matthias , Chenaux Virginie Anne 
Published: October 2020

Abstract
Current trends in turbomachinery design significantly reduce the mass ratio of structure to air, making them prone to flutter by aerodynamic coupling between mode shapes, also called coupled-mode flutter. The p–k method, which solves an aeroelastic eigenvalue problem for frequency and damping, respectively, excitation of the aerodynamically coupled system, was adapted for turbomachinery application using aerodynamic responses computed in the frequency domain (FD). A two-dimensional (2D) test case is validated against time-marching fluid–structure coupled simulations for subsonic and transonic conditions. A span of mass ratios is investigated showing that the adapted p–k method is able to predict the transition between aeroelastically stable and unstable cascades depending on the mass ratio. Finally, the p–k method is applied to a low mass ratio fan showing that the flutter-free operating range is significantly reduced when aerodynamic coupling effects are taken into account.
