How a Catastrophe Found the Past Hurricane Floyd and the Rise of Historical Consciousness in Princeville, North Carolina
Authors: Adkins Calvin , Prskalo Ena , Kroll‐Smith Steve 
Published: April 2021

AbstractHistory has no voice. It requires those who care enough about the past to put it into words. But to narrate the past, we must be conscious of it. This paper is an inquiry into how a small town in North Carolina found its unique history in the wake of a catastrophic hurricane. In 1885, Princeville, North Carolina became the oldest town in America charted by free Blacks. In spite of its historical significance, over time the town's storied past was silenced. By the latter half of the 20th century, the unique place of Princeville in African‐American history, indeed in United States history, was known to only a few elderly people; and they did not talk about it. The reasons a muted past begins to matter are themselves rooted in history. In 1999 Princeville was flooded by the deluge that was Hurricane Floyd. In the midst of mayhem this wordless past found a voice. In this paper we explore how a massive storm created space for the emergence of an historical consciousness among the town's residents. We also look at how the people of Princeville are leveraging their new found past to secure a safer, more predictable future.
The Indigenization of American Sociology in Japan: The Contribution of Kazuko Tsurumi
Authors: Yazawa Shujiro 
Published: April 2021

AbstractThis paper is an investigation of attempts at endogenization and indigenization in the history of sociology in Japan. The author begins by presenting a short history of Japanese sociology. While the issues of endogenization and indigenization had been raised in the 1910s, imperialism and the militarization of the Emperor state and society blocked this form of development. Japanese social sciences have thus mainly followed the model of Western social sciences. The issue of indigenization gained attention after World War II and especially after the late 1960s, which was a time of reflection on the extreme influence of American sociology. In this context, this paper investigates the development of Kazuko Tsurumi’s sociology, which is one of the best examples of work that deals with the issue of indigenization. Tsurumi analyzes social change from pre‐World War II to post‐World War II Japan by drawing on sociological functionalism. However, Tsurumi suggests that Kunio Yanagita’s theory of folklore and ethnology provides a stronger explanatory framework than functionalism, and contends that Kumagusu Minaka has developed an approach rooted in East Asia. Tsurumi advances this indigenous development theory based on the work of Yanagita and Minakata, and at the same time internationalizes this theory. This paper concludes that Tsurumi’s theory is an important medium between Western sociology and Eastern sociology.

Published: April 2021

AbstractObjectivesRecruiting/retaining healthcare professionals within rural and underserved communities in the United States remains a challenge. The West Virginia University Institute for Community and Rural Health implemented a service scholarship program in 2011 to address a lack of dental and primary care.MethodsDental and medical students commit to practice 12‐months full time following graduation in a Health Profession Shortage Area (HPSA) or Rural Urban Commuting Area (RUCA) in West Virginia for each $25,000 received.ResultsSince inception of the program, 20 of 23 (87 percent) dental recipients had completed their service commitment, 17 (85 percent) are still practicing in WV, and 3 (13 percent) are fulfilling their commitment. Four of 20 medical recipients have repaid (2) or fulfilled (2) program commitments and 16 are completing commitments or deferred during training. Retention rate is 82 percent for both dental and medical professionals following program completion.ConclusionsService scholarships effectively engage students to provide care in rural/underserved areas and remain there after program completion.
Agreement of blood glucose measured with glucose meter in arterial, central venous, and capillary samples in adult critically ill patients

Published: April 2021

AbstractBackgroundThe measurement of blood glucose in critically ill patients is still performed in many ICUs with glucose meters and capillary samples. Several prevalent factors in these patients affect the accuracy of the results and should be interpreted with caution. A weak recommendation from the Surviving Sepsis Campaign (SSC) suggests the use of arterial blood rather than capillary blood for point of care testing using glucose meters.Aims and objectivesTo analyse the agreement between arterial, central venous, and capillary blood samples of glucose values measured by glucose meter in critically ill patients and study potential confounding factors.DesignProspective cross‐sectional study in a general intensive care unit (ICU). Patients needing insulin treatment (subcutaneous or intravenous) and blood glucose control were included.MethodsStandardized collection of blood samples and measurement of glucose values with a glucometer. Agreement was studied by the Bland–Altman method and stratified analysis of disagreement‐survival plots was used to study the influence of haematocrit, pH range, SOFA score, capillary refilling time, intravenous insulin infusion, and lactic acid.ResultsA total of 297 measurements from 54 patients were included. The mean arterial blood glucose was 150.42 (range 31–345 mg/dL). In the graphical analysis, there is a poor agreement both in capillary and venous central to arterial samples, but in opposite direction (underestimation of capillary and overestimation of central venous). Factors associated with a reduction in the agreement between arterial and capillary samples were elevated lactate, poor capillary refilling, and hemodynamic failure. Patients without hemodynamic compromise have an acceptable agreement with values for absolute differences of 16 mg/dL for a disagreement of 10%.ConclusionsIn critically ill patients, the measurement of blood glucose with a glucose meter should be performed with arterial samples whenever possible. Capillary samples do not accurately estimate arterial blood glucose values in patients with shock and/or vasoactive drugs and underestimate the values in the range of hypoglycemia. Venous samples are subject to error because of potential contamination.Relevance to clinical practiceThis study adds support to the recommendation of using arterial blood rather than capillary or venous blood when using glucose meters in critically ill patients, especially in those with hemodynamic failure.

AbstractThe tomato leaf miner, Tuta absoluta (Meyrick), is one of the serious insect pests in tomato and potato farms. Along with acute toxicity, effects of emamectin benzoate alone and mixed with some conventional insecticides on esterase enzymes and the protein content of T. absoluta second‐instar larvae were assessed in the current study. After 72 h exposure time, emamectin benzoate had the most toxicity (LC50 = 0.52 mg a.i. L−1), followed by azadirachtin (LC50 = 5.19 mg a.i. L−1), indoxacarb (LC50 = 7.13 mg a.i. L−1), imidocloprid (LC50 = 44.63 mg a.i. L−1), thiacloprid (LC50 = 293.92 mg a.i. L−1) and lambda‐cyhalothrin (LC50 = 610.08 mg a.i. L−1). Although emamectin benzoate mixed with either azadirachtin or indoxacarb at LC15: LC15 (Lethal Concentration to kill 15% tested insects) ratio had synergistic effects, its combination with imidacloprid or thiacloprid showed additive interactions. However, emamectin benzoate mixed with imidacloprid at both LC25: LC25 and LC50: LC50 ratios showed synergistic effects. Lambda‐cyhalothrin mixed with emamectin benzoate showed an antagonistic interaction in all tested ratios. α‐esterase activity of larvae increased when emamectin benzoate was mixed with thiacloprid in comparison with emamectin benzoate alone and the control. Combinations of emamectin benzoate with either azadirachtin or indoxacarb significantly reduced the total protein content of larvae. Generally, it can be concluded that the combination of emamectin benzoate with either azadirachtin, indoxacarb, or imidacloprid resulted in more negative impacts against T. absoluta larvae.
Roles and mechanisms of phospholipid transfer protein in the development of Alzheimer's disease

Published: April 2021

AbstractPhospholipid transfer protein (PLTP) is a complex glycosylated protein that mediates the transfer of phospholipids, unesterified cholesterol, diacylglycerides, specific apolipoproteins, and tocopherols between different classes of lipoproteins as well as between lipoproteins and cells. Many studies have associated PLTP with a variety of lipid metabolic diseases. However, recent studies have indicated that PLTP is highly expressed in the brain of vertebrate and may be related to many central nervous system diseases, such as Alzheimer's disease. Here, we review the data and report the role and mechanisms PLTP in Alzheimer's disease.
Facilitating and motivating support: How support‐seekers can affect the support they receive in times of distress
Authors: Forest Amanda L. , Walsh Rebecca M. , Krueger Kori L. 
Published: April 2021

AbstractWhen people seek support in times of distress, receiving high‐quality support is critical to personal and relational well‐being. A rich body of work has examined support processes, but the role that support‐seekers play in eliciting support has received surprisingly limited attention. Yet, theory and research indicate that seekers’ behavior prior to and during support transactions shapes the support they receive. In the present paper, we summarize the literature on support‐seeking, describing how particular behaviors that seekers enact (deliberately or incidentally) affect their support receipt. We describe how each behavior facilitates (or hinders) providers’ ability to provide effective support and/or motivates (or demotivates) providers’ support provision efforts, and we consider why some people fail to enact certain support‐eliciting behaviors. Finally, we discuss the implications of our facilitate and motivate approach and identify important directions for future research. This work represents a promising springboard for examining a surprisingly underappreciated perspective in support transactions.

ABSTRACT

Objective:
The objective of this scoping review is to describe health care organizational structures and processes that support implementation of nurse-led, evidence-based practice projects resulting in improvements in outcome measures.

Introduction:
Many health care organizations claim to support evidence-based practice methodology; however, a gap exists between knowledge generation and its use in routine clinical practice. This scoping review protocol will examine the status of organizational factors impacting implementation of evidence-based practices and reported outcomes.

Inclusion criteria:
This scoping review will consider all literature that includes descriptions of health care organizations’ structures or support of evidence-based nursing programs or efforts that include outcomes. Health care organizations are defined as primary/secondary/tertiary, public/private, for profit/non-profit hospitals, medical centers, or multi-hospital systems. Literature will be excluded if the evidence-based practice project does not report the organizational structures that supported the implementation for the project. In addition, literature will be excluded if the program is not inclusive of nursing.

Methods:
Literature published in English from 1992 to present will be included. The databases to be searched include MEDLINE, CINAHL, Cochrane, and Embase. The search for unpublished evidence and gray literature will include ProQuest Dissertations & Theses Global, ANCC Magnet conferences, and government publications. Retrieval of full-text studies and data extraction will be performed independently by two reviewers. The extracted data will be presented in a tabular format with accompanying narrative summary.

Published: April 2021

ABSTRACT

Objective:
The objective of this review is to review the existing evidence on definitions, concepts, measurement instruments, and interventions for chronic fatigue in spinal cord injury.

Introduction:
Chronic fatigue in people with spinal cord injury is an under-studied issue that affects between 25% and 56.6% of people with spinal cord injury. There are questions about how it is defined and managed due to its complex, multifactorial nature and relationship with related conditions. No overview of chronic fatigue in spinal cord injury exists and we are in need of a shared definition of chronic fatigue, as well as a comprehensive review of concepts and evidence supporting outcome instruments and interventions.

Inclusion criteria:
This review will include empirical and non-empirical studies that focus on definitions, concepts, measurement instruments, and interventions for chronic fatigue in spinal cord injury. Studies that focus on peripheral muscle fatigue will only be included if they include chronic fatigue as a secondary outcome.

Methods:
This review will be done in three phases. Phase I will provide an overview of definitions of chronic fatigue in spinal cord injury and will include a qualitative analysis of concept attributes and characteristics. Phase II will focus on factors related to chronic fatigue and measurement instruments used to measure chronic fatigue, and phase III will focus on interventions. Full texts will be screened by two independent reviewers against inclusion criteria. Results will be presented in tabular form with a narrative summary.
Transfer Learning for Detection of Combustion Instability Via Symbolic Time-Series Analysis
Authors: Bhattacharya Chandrachur , Ray Asok 
Published: April 2021

Abstract
Transfer learning (TL) is a machine learning (ML) tool where the knowledge, acquired from a source domain, is “transferred” to perform a task in a target domain that has (to some extent) a similar setting. The underlying concept does not require the ML method to analyze a new problem from the beginning, and thereby both the learning time and the amount of required target-domain data are reduced for training. An example is the occurrence of thermoacoustic instability (TAI) in combustors, which may cause pressure oscillations, possibly leading to flame extinction as well as undesirable vibrations in the mechanical structures. In this situation, it is difficult to collect useful data from industrial combustion systems, due to the transient nature of TAI phenomena. A feasible solution is the usage of prototypes or emulators, like a Rijke tube, to produce largely similar phenomena. This paper proposes symbolic time-series analysis (STSA)-based TL, where the key idea is to develop a capability of discrimination between stable and unstable operations of a combustor, based on the time-series of pressure oscillations from a data source that contains sufficient information, even if it is not the target regime, and then transfer the learnt models to the target regime. The proposed STSA-based pattern classifier is trained on a previously validated numerical model of a Rijke-tube apparatus. The knowledge of this trained classifier is transferred to classify similar operational regimes in: (i) an experimental Rijke-tube apparatus and (ii) an experimental combustion system apparatus. Results of the proposed TL have been validated by comparison with those of two shallow neural networks (NNs)-based TL and another NN having an additional long short-term memory (LSTM) layer, which serve as benchmarks, in terms of classification accuracy and computational complexity.
Short-Term Optimization of a Combined Cycle Power Plant Integrated With an Inlet Conditioning Unit

Published: April 2021

Abstract
Under new scenarios with high shares of renewable electricity, combined cycle gas turbines (CCGTs) are required to improve their flexibility to help balance the power system. Simultaneously, liberalization of electricity markets and the complexity of its hourly price dynamics are affecting the CCGT profitability, leading the need for optimizing its operation. An inlet conditioning unit (ICU) offers the benefit of power augmentation and “minimum environmental load” (MEL) reduction by controlling the gas turbine (GT) inlet temperature using cold thermal energy storage (TES) and a heat pump (HP). Consequently, an evaluation of a CCGT integrated with this unit including a day-ahead optimized operation strategy was developed in this study. To establish the hourly dispatch of the power plant and the operation mode of the ICU, a mixed-integer linear programing (MILP) optimization was formulated, aiming to maximize the operational profit of the plant within a 24 h horizon. To assess the impact of the unit operating under this dispatch strategy, historical data have been used to perform annual simulations of a reference power plant located in Turin, Italy. Results indicate that the power plant's operational profit increases by achieving a wider operational range during peak and off-peak periods. For the specific case study, it is estimated that the net present value (NPV) of the CCGT integrated with the ICU is 0.5% higher than the CCGT without it. Results also show that the unit reduces the MEL by approximately 1.34% and can increase the net power output by 0.17% annually.
Transient Flutter Stability Analysis of Structural Mistuned Blisk by Energy Growth Method
Authors: Ouyang Luohui , Bi Qingzhen , Chen Hua , Shang Hai , Zhu Limin 
Published: April 2021

Abstract
Blisks suffer from flutter, a self-sustained vibration caused by aerodynamic coupled forces. This instability could cause serious damage to the blades and the machine. Flutter stability is usually analyzed based on the eigenvalue method in the aspect of the linear structural dynamic system, which transforms a dynamics stability analysis into a point of equilibrium in an infinite time scale. However, in reality, most of the blisk vibrations arise on a finite time horizon. The transient vibration amplification may cause serious damage. This paper proposes a transient flutter stability analysis method in a finite time for structural mistuned blisk based on the energy growth method. First, two common blisk models coupled aerodynamic force with different complexity are built and are all expressed in the state space representation. A novel energy growth method is then employed to analyze the transient stability and to find the maximum energy growth of the models. The optimal initial condition which leads to the maximum energy growth is obtained. A new flutter stability criterion is developed to consider the transient stability based on the energy growth method and the infinite time stability based on the eigenvalue method. The new transient stability method is verified by two numerical studies. It is found that the structural mistuned blisk model which is traditionally predicted stable still has a transient instability in a finite time due to the non-normal property of the dynamic state matrix.
Additively Manufactured Compliant Hybrid Gas Thrust Bearing for Supercritical Carbon Dioxide Turbomachinery: Experimental Evaluation and Fluid–Structure Model Predictions
Authors: Ertas Bugra , Gary Keith , Delgado Adolfo 
Published: April 2021

Abstract
This paper presents rotating test results and advances an analytical predictive fluid–structure model for a new type of gas-lubricated thrust bearing fabricated using direct metal laser melting. The bearing concept in this study is a compliant hybrid gas thrust bearing that uses external pressurization to increase load carrying capacity, where the testing campaign in this study was only focused on steady-state static performance. The need for the bearing concept comes from enabling highly efficient supercritical carbon dioxide (sCO2) turbomachinery by replacing oil-lubricated bearings with process gas lubrication. Leveraging the process gas of the turbomachine for bearing lubrication results in lowered bearing power loss, simplified mechanical design, and allows for novel oil-free hermetic drivetrains resulting in an efficient emission-free system. The new concept utilizes hydrostatic pressurization on individual tilting pads flexibly mounted with hermetic squeeze film dampers (HSFDs). This paper focuses on rotating tests of a 173 mm outer diameter gas thrust bearing in air up to 10 krpm and hydrostatic inlet pressures to 365 psi (2.52 MPa). The influence of thrust runner speed and bearing inlet pressure on force deflection characteristics and load carrying capability of the gas film were experimentally evaluated. This work also advances a predictive fluid–structure thrust bearing model using an isothermal ideal-gas-based compressible Reynolds flow equation directly coupled to a lumped stiffness element possessing axial and rotational degrees-of-freedom. The rotating testing demonstrated load capability of 1816 lbs (8.1 kN), which equates to a thrust bearing unit load of 67 psi (0.46 MPa). Gas film force–deflection curves reveal a nonlinear relationship between thrust load and film clearance. Comparison of film thickness values with the predictive model show good agreement under high load and inlet pressure, however deviate as load and pressure decrease. Load capability was shown to increase with increasing hydrostatic inlet pressure, while the increase in thrust runner speed revealed a small decrease in load capacity.

Abstract
In this paper, dynamics of higher order multiple input multiple output (MIMO) cascade nonlinear systems, MIMOn, (n&gt;3), is analyzed using simulation of bifurcation and Lyapunov diagrams and spatial phase portraits. One of the characteristics of these systems is the possibility of spatial hyperchaos appearance. Control of spatial hyperchaos in MIMOn systems using modified Pyragas method is analyzed, also. The results are illustrated by example of MIMO6 system.
