Factors that affect your plant power bill

The author attempts to provide an understanding of the time-of-use costing of electrical energy and how to take advantage of it. The purpose of power rate structures is explained, and an understanding of power rate structures is provided. It is shown that by being aware of the incremental costs in their rate, managers are able to accurately evaluate the benefits of electrical kilowatt demand reduction and kilowatthour energy management projects. Also, by being aware of other rate options, managers can add or switch to other rate structures that may be better suited to their operations. >
EatWell: sharing nutrition-related memories in a low-income community

Low-income African American communities face a disproportionate amount of diet-related health problems in the United States. To address this issue, we developed EatWell, a system that allows people to use their cell phones to create voice memories describing how they have tried to eat healthfully in their neighborhoods (e.g., at local restaurants) and listen to the memories that others have created. In this paper, we describe the results of our field trial of EatWell, specifically characterizing how our participants were able to craft stories that were both emotive and culturally-relevant, the challenges that arose in creating these memories and finally how sharing these stories facilitated a sense of community empowerment. We conclude by presenting implications for the design of future applications that facilitate the sharing of health-related experiences.
Efficiency in Assessment: Can Trained Student Interns Rate Essays as Well as Faculty Members?

What are the most efficient and effective methods in measuring outcomes for assurance of learning in higher education? This study examines the merits of outsourcing part of the assessment workload by comparing ratings completed by trained student interns to ratings completed by faculty. Faculty evaluation of students’ written work samples provides the most detailed, actionable data useful for improving the curriculum. While this approach may be efficacious, it is also labor-intensive. Both the faculty and student interns were trained to use a scoring rubric developed for this assessment to rate undergraduate student essay responses to an ethical reasoning scenario. The convergent validity, discriminant validity, and source bias showed no significant difference between the values for the student raters versus those for the faculty raters. These findings support the hypothesis that trained student interns can do as well as faculty at evaluating undergraduate student work samples.
Relation between ventricular repolarization duration and cardiac cycle length during 24-hour Holter recordings. Findings in normal patients and patients with long QT syndrome.

BACKGROUND The interval from the R wave to the maximum amplitude of the T wave (RTm) contains the heart rate dependency of ventricular repolarization. METHODS AND RESULTS A computer algorithm was developed to quantify the RTm and preceding RR intervals for each of more than 50,000 beats on 24-hour ambulatory electrocardiographic (Holter) recordings to evaluate the dynamic relation between repolarization duration and cycle length. The relation of RTm to the preceding RR interval (RTm/RR slope) was determined by the best-fit linear regression equation between these two parameters. Eleven normal subjects and 16 patients with long QT syndrome (LQTS) were investigated. Six of the normal subjects had Holter recordings obtained before and after beta-blocker therapy. beta-Blockers were associated with a significant (p = 0.005) reduction in the RTm/RR slope from 0.13 +/- 0.02 to 0.10 +/- 0.02. The mean value of the RTm/RR slope was significantly (p = 0.003) larger in the LQTS patients (0.21 +/- 0.08) than in normal subjects (0.14 +/- 0.03). CONCLUSIONS These findings indicate that 1) quantification of the dynamic relation between ventricular repolarization and RR cycle length can be obtained on a large number of Holter-recorded heart beats; 2) beta-blockers reduce the RTm/RR slope in normal patients; and 3) LQTS patients have an exaggerated delay in repolarization at long RR cycle lengths.
Adults with congenital heart disease: at long last, guidelines for arrhythmia management.

Beginning with the first successful surgical closure of a patent ductus arteriosus in 1938, to open heart repair of septal defects in 1955 and into the current era, children born with potentially fatal congenital heart defects are now surviving and attaining adulthood in numbers not previously envisioned. The concept of “long term” survival, originally meaning 10 years postrepair, has been superseded by survival beyond 20 and even 40 years. At the current time, population estimates indicate that there are now nearly 3 million adults with congenital heart disease (ACHD) in the United States, Canada, and Europe; and that number is growing. Since a “repaired” congenital heart does not imply “normal,” most of these patients will experience some complications, requiring lifelong medical care (Fig. 1). Prominent among these complications are arrhythmias that contribute to impaired quality of life, morbidity, and mortality. And although expert consensus guidelines dealing with various aspects of arrhythmia identification and patient management have been published since the 1980s, dealing primarily with ischemic heart disease, none fully apply to this growing ACHD population. At the recent 35th Scientific Sessions of the Heart Rhythm Society, the Pediatric and Congenital Electrophysiology Society (PACES) presented the first-ever expert consensus arrhythmia management guidelines that focus specifically on the ACHD patient, taking into consideration specific cardiac anatomies, surgical repairs, and their sequelae, including heart failure.1 The 22member, multidisciplinary and international writing committee included representatives from, and the publication was endorsed by, the American College of Cardiology, American Heart Association, Heart Rhythm Society, European Heart Rhythm Association, Canadian Heart Rhythm
Predicting systolic anterior motion after mitral valve reconstruction: using intraoperative transoesophageal echocardiography to identify those at greatest risk

Objectives We set out to determine if intraoperative pre-bypass transoesophageal echocardiography could assist in predicting which patients are at greatest risk for systolic anterior motion (SAM) after mitral valve repair (MVR). Methods Three hundred and seventy-five consecutive patients who underwent reconstructive MVR surgery for degenerative disease were included. Data were collected using intraoperative echocardiographic images taken prior to the initiation of cardiopulmonary bypass. Based on the physiology of SAM, we postulated that 11 parameters could be potential risk factors for SAM: left ventricular ejection fraction (LVEF), left ventricular end-systolic dimension, left ventricular end-diastolic dimension (LVEDD), basal septal diameter (basal-interventricular septal diameter in diastole (IVDd)), mid-ventricular septal diameter (mid-IVDd), coaptation-septal distance (c-sept), anterior leaflet height, posterior leaflet height, aorto-mitral angle, mitral annular diameter and left atrial diameter. These parameters were measured and recorded by a blinded single operator. Independent predictors of SAM were identified using multiple logistic regression analysis. Results Of the 375 patients, 345 (92%) did not develop SAM (No-SAM group), while 30 (8%) developed intraoperative or postoperative SAM (SAM group). The mean age was 56.8 ± 12.8 and 56.7 ± 13.8 in the No-SAM and SAM groups, respectively. The incidence of fibroelastic deficiency, forme fruste and Barlow's disease was similar in both groups. All patients received a complete annuloplasty ring as part of the repair. There was no statistical difference in the mean ring size used in each group. EF was similar in the No-SAM (56.2% ± 8.1) and SAM (57.0% ± 9.2) P = 0.63) groups. Independent predictors of developing SAM after valve repair were: EDD 15 mm (OR 3.80; P = 0.012) and basal septal diameter ≥ 15 mm (OR 3.63; P = 0.039). Conclusions The risk for SAM can be predicted using intraoperative transoesophageal echocardiography. The combination of a smaller left ventricle, tall posterior leaflet, narrow aorto-mitral angle and enlarged basal septum significantly increases the risk for SAM. Knowing these parameters prior to valve repair can assist the surgeon in adjusting their repair technique to minimize the risk.
LAMINAR AND TRANSITIONAL BOUNDARY LAYER ENTROPY GENERATION OVER A FLAT PLATE UNDER FAVORABLE AND ADVERSE PRESSURE GRADIENTS

Minimizing entropy generation is important to improve the efficiency of any system. The objective of this study is to use computational fluid dynamics (CFD) to elucidate the effects of pressure gradients on entropy generation rates in laminar and transitional boundary layers. The commercial CFD software, ANSYS FLUENT, is employed. The favorable and adverse pressure gradients are generated using various curved slip top walls. Bypass transition is simulated using the mean inlet velocity and Reynolds stresses from the direct numerical simulation (DNS) conducted by Nolan and Zaki [1]. Various turbulence and transitional models are employed and the results are compared to the DNS data. The factor of safety method is used to evaluate numerical error and grid uncertainties. Three systematically refined meshes are used to evaluate grid convergence. Monotonic convergence is achieved for all simulations with small grid uncertainties. The boundary layer correlation function, F(λ), the shear stress correlation, S(λ), and the dissipation coefficient, Cd, are calculated for the laminar CFD results. The dissipation coefficient, Cd and the intermittency, γ, are also calculated for the bypass transition CFD results. The laminar CFD results show better agreement with the correlation developed by McEligot than with the Thwaites correlation for F(λ) and S(λ). Overall, the percentage differences between the CFD results and the correlations increase as the magnitude of the pressure gradient variable, β, increases. The solvers and turbulence models in the transitional simulations are similar to the study by Ghasemi et al [2]. However, this study uses a much finer grid and improved boundary conditions for the inlet. These changes show an improvement for most turbulence models by comparison with the DNS results, especially for the location of transition.
Alcohol Misuse and Associations with Childhood Maltreatment and Out-of-Home Placement among Urban Two-Spirit American Indian and Alaska Native People

This study examined associations between alcohol misuse and childhood maltreatment and out-of-home placement among urban lesbian, gay, and bisexual (referred to as two-spirit) American Indian and Alaska Native adults. In a multi-site study, data were obtained from 294 individuals who consumed alcohol during the past year. The results indicated that 72.3% of men and 62.4% of women engaged in hazardous and harmful alcohol use and 50.8% of men and 48.7% of women met criteria for past-year alcohol dependence. The most common types of childhood maltreatment were physical abuse among male drinkers (62.7%) and emotional abuse (71.8%) among female drinkers. Men and women reported high percentages of out-of-home placement (39% and 47%, respectively). Logistic multiple regressions found that for male drinkers boarding school attendance and foster care placement were significant predictors of past-year alcohol dependence. For female drinkers, being adopted was significantly associated with a decreased risk of past-year drinking binge or spree. Dose-response relationships, using number of childhood exposures as a predictor, were not significant. The results highlight the need for alcohol and violence prevention and intervention strategies among urban two-spirit individuals.
Atorvastatin for the Prophylaxis of Acute Graft-versus-Host Disease in Patients Undergoing HLA-Matched Related Donor Allogeneic Hematopoietic Stem Cell Transplantation (allo-HCT)

Abstract Statins possess potent immunomodulatory effects that may play a role in preventing acute graft-versus-host disease (aGVHD) after allogeneic hematopoietic cell transplantation (allo-HCT). We performed a phase II study of atorvastatin for aGVHD prophylaxis when given to allo-HCT recipients and their HLA-matched sibling donors. Atorvastatin (40 mg/day) was administered to sibling donors, beginning 14 days before the anticipated start of stem cell collection. Allo-HCT recipients (n = 40) received atorvastatin (40 mg/day) in addition to standard aGVHD prophylaxis. The primary endpoint was cumulative incidence of grades II to IV aGVHD at day 100. Atorvastatin was well tolerated, with no attributable grades III to IV toxicities in donors or their recipients. Day 100 and 180 cumulative incidences of grades II to IV aGVHD were 30% (95% confidence interval [CI], 17% to 45%) and 40% (95% CI, 25% to 55%), respectively. One-year cumulative incidence of chronic GVHD was 43% (95% CI, 32% to 69%). One-year nonrelapse mortality and relapse incidences were 5.5% (95% CI, .9% to 16.5%) and 38% (95% CI, 18% to 47%), respectively. One-year progression-free and overall survival rates were 54% (95% CI, 38% to 71%) and 82% (95% CI, 69% to 94%). One-year GVHD-free, relapse-free survival was 27% (95% CI, 16% to 47%). These results did not differ from our historical control subjects (n = 96). Although safe and tolerable, the addition of atorvastatin did not appear to provide any benefit to standard GVHD prophylaxis alone.
Sixteen personality factor profiles of collegiate wrestlers.

Abstract Ninety-four amateur and collegiate wrestlers were studied with the Sixteen Personality Factor Questionnaire. Personality profiles were studied across different levels of demonstrated achievement in wrestling. Discriminant function analyses failed to establish any profile differences between criterion groups. Groups assessed were (a) a superior group comprised of 28 wrestlers from the United States Olympic team, NCAA or NAIA champions or place winners, (b) an excellent group comprised of 33 collegiate wrestlers who were varsity representatives, rated excellent by their coach, and who had won at least 60 percent of their matches during the season; (c) an average to below average group of the 33 wrestlers remaining on four college teams secured for the study. When compared to norms, wrestlers demonstrated a significant departure from average on factor I indicating tough-mindedness, self-reliance, and masculinity. No support was found for the suggestion that wrestlers may possess a neurotic profile.
A 320MHz–2.56GHz low jitter phase-locked loop with adaptive-bandwidth technique

This paper presents a novel adaptive-bandwidth phase-locked loop (PLL) using a closed loop voltage controlled oscillator (VCO). The adaptive-bandwidth PLL uses the gain of closed loop VCO to obtain a constant unity gain bandwidth over an operating frequency range. Furthermore, a charge pump (CP) current is proportional to the current of VCO so that CP current is in proportion to the VCO frequency. Since the adaptive-bandwidth is optimized over the VCO frequency, an integrated RMS jitter is reduced in comparison to a conventional fixed-bandwidth PLL. We simulate the proposed PLL in 130 nm CMOS technology at 1.2 V power supply. The integrated RMS jitter of the proposed adaptive-bandwidth PLL is 2.35 psec which is 70% smaller than the conventional PLL. This adaptive-bandwidth PLL consumes 2.6 mW at 2.56 GHz output frequency.
Dixanthylurea (N, N'-di-9H-Xanthen-9-ylurea).

C27H20N2O3, MW = 420, orthorhombic, Pbc21, a = 4.686(2), b = 16.784(8), c = 25.924(10)A, V = 2039A3, dobs = 1.37 g cm-3 (flotation), d calc = 1.369g cm-3, Z = 4. The structure has been determined by direct methods and refined to R = 0.045 based on 1419 independent reflections. No crystallographic symmetry element is present in the dixanthylurea molecule. In fact, the molecule is considerably distorted from any possible mirror symmetry. The molecules are hydrogen bonded in an infinite chain along the a-axis. The compound is of interest because of its role in the analytical determination of urea.

The Effect of Relational and Interactive Aspects of Parasocial Experiences on Attitudes and Message Resistance

This study examines direct and interaction effects of parasocial interactions (PSIs) and relationships (PSRs) on message resistance (reactance and counterarguing) and message-consistent attitudes. PSI involves the give-and-take within the media encounter, whereas PSR entails the relational bonding with the media figure that continues to exist outside the context of any particular media exposure. A 2 (high/low PSI) × 2 (high/low PSR) experiment revealed that PSI (but not PSR) can increase message resistance, particularly when PSR is low. No significant effects of PSR/PSI on attitudes were found. The study suggests that, contrary to past theorization, PSIs may facilitate, rather than reduce, message resistance. Furthermore, the findings highlight the importance of considering PSIs and PSRs as distinct constructs in media effects research.
Age, period, and cohort effects in synthetic cannabinoid use among US adolescents, 2011-2015.

Abstract Background Synthetic cannabinoids use has been a public health concern given association with hospitalization and death among users. While national reports estimate that reported use is declining among adolescents, differences by birth cohort may indicate subgroups who remain at higher risk, both in the overall adolescent population and among demographic subgroups. Methods We estimated age, period, and cohort models of self-reported past-year synthetic cannabinoid use (queried as “synthetic marijuana” [“K2,” “Spice”]) among 54,865 adolescents aged 13–19 attending high school from 2011 to 2015. Results Past-year use decreased from 11.86% in 2011 to 4.75% in 2015. This decrease was best represented as a linear downward trend. When stratified by key covariates, however, results indicated evidence of a positive cohort effect for students of higher socioeconomic status (SES). For those students, use did not decrease at the same rate as the overall population; younger cohorts of high SES students remain at higher risk for synthetic cannabinoid use than older cohorts as well as lower SES peers. A similar and stronger association was found for frequent marijuana users (≥20 occasions of past-year use). Multi-level models indicated that groups at highest risk included older adolescents, Hispanics and other/mixed race students, cigarette users, and frequent marijuana users. Conclusion Synthetic cannabinoid use is associated with morbidity as well as mortality; continued attention to reducing synthetic cannabinoid use remains an important public health priority to maximizing student health.
USP44 Is an Integral Component of N-CoR that Contributes to Gene Repression by Deubiquitinating Histone H2B

Summary Decreased expression of the USP44 deubiquitinase has been associated with global increases in H2Bub1 levels during mouse embryonic stem cell (mESC) differentiation. However, whether USP44 directly deubiquitinates histone H2B or how its activity is targeted to chromatin is not known. We identified USP44 as an integral subunit of the nuclear receptor co-repressor (N-CoR) complex. USP44 within N-CoR deubiquitinates H2B in vitro and in vivo, and ablation of USP44 impairs the repressive activity of the N-CoR complex. Chromatin immunoprecipitation (ChIP) experiments confirmed that USP44 recruitment reduces H2Bub1 levels at N-CoR target loci. Furthermore, high expression of USP44 correlates with reduced levels of H2Bub1 in the breast cancer cell line MDA-MB-231. Depletion of either USP44 or TBL1XR1 impairs the invasiveness of MDA-MB-231 cells in vitro and causes an increase of global H2Bub1 levels. Our findings indicate that USP44 contributes to N-CoR functions in regulating gene expression and is required for efficient invasiveness of triple-negative breast cancer cells.
Creative Exposure Intervention as Part of Clinical Treatment for Adolescents Exposed to Bullying and Experiencing Posttraumatic Stress Disorder Symptoms

ABSTRACTResearch is beginning to emerge which demonstrates that bullying is a potential risk factor for the development of posttraumatic stress disorder (PTSD) symptoms among adolescents (Crosby, Oehler, & Capaccioli, 2010). Cognitive-behavioral therapy (CBT), mindfulness training, and art therapy techniques are garnering attention in the counseling literature for their effective treatment of PTSD (Barlow, 2014; Bazargan & Pakdaman, 2016; Bernstein, Tanay, & Vujanovic, 2011). This article introduces an eclectic intervention, incorporating these three techniques, designed for work with adolescents experiencing bully-related PTSD symptoms. This article presents a case example to illustrate Creative Exposure, which can be used in one session or across multiple sessions. This technique is intended for use by counselors with the credentials and training to provide trauma treatment.
Transference-Focused Psychotherapy (TFP) Principles in Clinical Crisis Management

Transference-focused psychotherapy (TFP) principles can aid clinicians in crisis management in a variety of settings. The TFP contract has multiple provisions related to expectable crises explored in advance of starting the treatment. The essential elements of severe personality disorder pathology, specifically the predominant use of splitting-based defenses, almost guarantee intermittent crises will arise during the course of treatment. TFP interventions, including the clinician’s ability to monitor the three channels of communication, “naming the actors” to manage the patient’s heightened affective state, and identification of dominant object relations dyads and their reversals, are central tools in crisis management. These TFP-informed interventions can be of use for clinicians managing crises in settings across psychiatry and medicine; TFP principles have applicability even when the clinician is required to manage crises in situations other than an extended individual treatment. Use of TFP principles in crisis management can be appreciated as central elements of good risk management.
A Video-Aided Semantic Analytics System for Disaster Information Integration

We present a novel web-based system and a video-aided mobile application that allows emergency management personnel to access to prompt and relevant disaster situation information. The system is able to semantically integrate text-based disaster situation reports with related disaster videos taken in the field. The system is adapted to the video concept detection model and automates the procedure of file deployment and data manipulation. In addition, through an intuitive and seamless Apple iPad application, the users are able to interact with the system in various places and conditions and thus provide a more effective response. The system is demonstrated via its iPad application, which aims to provide relevant and feasible information for a disaster situation of interest.
GREENHOUSE EFFECT AND GLOBAL WARMING

We face Conflicts between human development and nature Capacity to Provide The resources for such development. This is a great paradox the countries that have most benefited from industrial development by producing greenhouse gases. The atmosphere surrounding the earth, heats the soil and the Plants also. Greenhouse is the body which allows the short wave length incoming solar radiation to come in but does not allow the long wave outgoing terrestrial infrared radiation to scope in a way and atmosphere energy going up. Green house where co2 acts as like a glass windows. Co2 and water Vapors in the atmosphere transmit short wave length solar radiation but reflect the longer wave length heat radiation from warmed surface of the co2 molecules are transparent to sunlight but not to the heat re action .So the trap and re enforce the solar heat stimulating an effect which is properly known as Greenhouse effect.
Computationally efficient fragility assessment using equivalent elastic limit state and Bayesian updating

Abstract Conventionally, the seismic response of primary structures such as buildings and secondary systems such as piping is evaluated through uncoupled analyses. Many studies have illustrated that the two systems interact in many different ways (mass interaction, non-classical damping, phasing, etc.). An analysis of the coupled system is not only rational but also eliminates the excessive conservatism that exists in an uncoupled analysis. Consequently, fragility assessments based on uncoupled analysis are also incorrect and a coupled analysis must be conducted in such evaluations. However, nonlinear analyses of such complex systems particularly in the context of fragility assessment, which requires a large number of nonlinear analyses, becomes computationally prohibitive. Tadinada and Gupta (2017) presented an equivalent elastic limit state concept with an intent to reduce the computational effort needed in these assessments and yet evaluate the seismic fragility with sufficient accuracy. This paper outlines some of the limitations that have been experienced in the use of originally proposed equivalent limit-state formulation and presents valuable enhancements. The novel contribution of this study is focused on accounting for the effect of uncertainty in nonlinear characteristics and the effect of non-classical damping. Unlike the originally proposed formulation, the proposed formulation also considers the asymmetric variation of the equivalent limit state with respect to tuning ratio. Furthermore, a Bayesian approach is incorporated into the proposed methodology for increasing the accuracy of seismic fragilities in the case of tuned or nearly tuned primary-secondary systems. Numerical examples are used to illustrate that the modified form improves the accuracy for both the tuned and the detuned systems. In summary, the proposed approach provides an efficient framework of seismic fragility assessment and risk evaluation for coupled systems.

An integrated mass spectrometry platform enables picomole-scale real-time electrosynthetic reaction screening and discovery

The identification of new electrosynthetic pathways enables environmentally friendly synthetic applications. However, the development of miniaturized screening procedures/platforms to expedite the discovery of electrooxidation reactions remains challenging. Herein, we developed an integrated system that serves as a reactor and ion source in a single experimental step using only picomole-scale reactants to monitor electrooxidation in real-time. This reaction screening platform utilizes the intrinsic electrochemical capabilities of nano-electrospray ionization mass spectrometry. We validated the feasibility of this method by reproducing three known electrochemical reactions. We also discovered two new electroorganic reaction pathways: (i) C–N dehydrodimerization of 8-methyl-1,2,3,4-tetrahydroquinoline to construct a novel quinoline skeleton, and (ii) TEMPO-mediated accelerated electrooxidative dehydrogenation of tetrahydroisoquinolines. Moreover, the radical cations and key intermediates captured by this screening platform provided direct evidence for the mechanism of these novel electrochemical reactions.

Nursing Care of the Pediatric Cardiac Patient

Thorough assessment and support of cardiopulmonary function are essential in caring for every patient in the pediatric cardiac intensive care unit (CICU). The patient population in the CICU ranges from the preoperative patient awaiting cardiac surgery, the child with congestive heart failure, cardiomyopathy, or arrhythmias to the postoperative patient who has undergone palliation or corrective surgery for congenital heart disease. Nurses working in this environment must have exceptional assessment skills, clinical expertise, and a sound judgment to respond to constantly changing and potentially emergent situations. In addition, with the practice of holistic family-centered care, nurses must extend compassion and empathy to each child as well as to their parents, and extended family throughout their experience in the CICU. This chapter outlines basic cardiac assessment essential for the critical care nurse and defines clinical skills needed to care for the pediatric medical and surgical cardiac patient. The developmental needs of children in the CICU will be discussed within the context of a family-centered environment of care.
Two new species of rain beetle (Coleoptera: Pleocomidae: Pleocoma Le Conte, 1856) in the Pacific Northwest of the United State of America

A newly discovered population of rain beetles from south central Washington, United States of America is described as Pleocoma laker Marshall, new species. The only other species known from Washington, P. crinita Linsley, 1938, is restricted to include only populations north of the Columbia River. Rain beetles from Oregon, previously considered as P. crinita, are recognized as a distinct species: Pleocoma callisto Marshall, new species. A key to the identification of all described rain beetles in Oregon and Washington is provided.
The Other Trinity: Saurashtra Histories of Carnatic Music

The paper examines the place of Veṅkaṭaramaṇa Bhāgavatar (1781–1874), Kavi Veṅkaṭasūri (1818–90), and Nāyakī Svāmikaḷ (1843–1914)—three nineteenth-century figures—in the Saurashtra reimagining of the history of the South Indian music tradition. Worshiped as the mummūrti, these three poet/saint/musicians are regarded by the Saurashtra community of Madurai as the alternative to the deified figures of Tyāgarāja (1767–1847), Muttusvāmi Dīkṣitar (1775–1835), and Śyāma Śāstri (1762–1827), canonical to the South Indian classical music tradition as it develops in the late nineteenth and early twentieth centuries. Engaging with recent scholarship on the cultural histories of South Indian music, the paper moves between the center and the periphery, between the cities of Madras and Madurai, to chart the (continuing) work of the Saurashtra community in rewriting the script for South Indian music.
Acoustic Emission from a Porous Non-Woven Fiberglass Material

Acoustic emission (AE) signals are studied for a porous non-woven glass fiber material subjected to both static and cyclic compression. An experimental set-up for the measurement of acoustic signals emitted from the porous solid during mechanical loading is described, and the interpretation of AE signal data is established in the context of scaling laws originally developed for the description of earthquakes. The analysis of micro-CT images before and after loading quantifies that fiber fracture is a predominantly associated with fiber fracture. Several prior studies have established the use of the Gutenberg-Richter and Omori scaling laws for the analysis of AE signals under static loading, but it is unknown if and how such approaches can be extended to cyclic loading. First, static fatigue experiments establish a baseline response of the porous glass fiber material. It is demonstrated that the Gutenberg-Richter and Omori scaling laws can be used to describe AE for the present material. Subsequently, it is shown that the Gutenberg-Richter law still holds under cyclic compression loading. However, the Omori law needs to be replaced. A new scaling law is proposed here which relates the density change in compression to the AE signal. Finally, a relationship between the AE signal statistics and the mechanical damage rate is established for the material at hand.

Geocenter motion time series derived from GRACE GPS and LAGEOS observations

Accurate quantification of geocenter motion is important for maintaining the reference frame and estimating large-scale mass variations using the Gravity Recovery and Climate Experiment (GRACE) time-variable gravity solutions. Geocenter motion (equivalent to the variations in the degree-1 spherical harmonics of the gravity field) can be determined from different geodetic techniques and approaches, and the results generally show reasonable agreement, but significant differences still exist. To be more consistent with GRACE gravity solutions, here we present an improved approach to solve geocenter motion using GRACE GPS data. Over the past 15 years, GRACE satellites have acquired enough GPS data for studying the geocenter motion. In the meantime, data processing methods, reference system, and background geophysical models for GRACE precise orbit determination have also been significantly improved. Those aspects are very important for accurate determination of geocenter motion from GRACE GPS observations. For comparison, geocenter motion is also derived from LAGEOS satellite laser ranging (SLR) observations. With these independent geocenter motion solutions from GRACE GPS and LAGEOS SLR, we explore the reasons that lead to the differences between the solutions, and try to resolve these discrepancies. Daily geocenter motion time series from GRACE GPS data and 28-day geocenter variations from LAGEOS SLR observations for the time span 2003–2016 have been derived. Internal comparisons between the GRACE-A and GRACE-B geocenter motion time series and external comparisons between GRACE and LAGEOS show good agreements after using the improved approach. To verify the results, the annual geocenter motion from this study is compared with other recent geocenter motion solutions as well as predictions from geophysical models. The comparisons show reasonable agreements in both amplitude and phase with our improved approach.
Thrombolysis for Frostbite: A Case Study and Clinical Considerations

Abstract Frostbite injuries are becoming more common in the civilian population and are frequently associated with homelessness, mental illness, and alcohol and drug use and abuse. Taking care of these patients requires a multidisciplinary approach, initially by emergency medicine, the burn service, and interventional radiology, and eventually involving case management, social services, and occupational and physical therapy. Timely and rapid rewarming in conjunction with catheter-directed intravascular thrombolysis interventions can restore adequate perfusion to the patient's compromised digits. To improve patient outcomes, it is essential to obtain proper imaging and, if appropriate, immediately initiate an interventional radiology consultation for urgent thrombolysis treatment. This article presents a clinical case study of a patient who suffered frostbite injuries and underwent intravascular thrombolysis interventions that spanned a 24-hour period and required two interventional radiology procedures. Nursing care considerations and thrombolysis management in the emergency department, radiology department, and intensive care unit are reviewed.
School-Based 4-H Programming Series: Positive Youth Development (PYD) and Social Emotional Learning (SEL)—How They Complement Each Other

Positive Youth Development (PYD) promotes building life skills, leadership, and relationships, and Social Emotional Learning (SEL) promotes knowledge, responsibility, and caring. Just as 4-H uses PYD as a framework, so schools use SEL. A whole program approach with appropriate curriculum provide the skills necessary for youth to succeed. This new 5-page publication of the UF/IFAS 4-H Youth Development Program explores the complementary relationship between PYD and SEL in a school-based program setting.

Enhancing Short Circuit Capability of 1.2 kV SiC Power MOSFETs using a Gate-Source Shorted Si Depletion-Mode MOSFET in Series with the Source

Silicon carbide power MOSFETs are an attractive option to replace Si IGBTs in power conversion applications to reduce switching losses. Commercially available SiC Power MOSFETs do not have short-circuit (SC) capability matching those of Si IGBTs, thus prohibiting their use in some applications. This paper proposes an innovative method to improve the short circuit capability of 1.2 kV SiC power MOSFETs by using a gate-source shorted Si power depletion-mode MOSFET in series with the source electrode. Extension of the short circuit time from 4.8 μs to beyond 7.5 μs for a 1.2 kV SiC power MOSFET operating at a drain bias of 800 V and gate bias of 20 V has been experimentally demonstrated. Static and dynamic characteristics were measured to demonstrate minimal impact on power losses.
Epidemiology of Fireworks-Related Injuries to the Upper Extremity in the United States From 2011 to 2017

Purpose Fireworks may result in a wide spectrum of injury to the upper extremity ranging from mild burns to amputation. In this cross-sectional study, we describe the epidemiology of upper-extremity injuries in the United States associated with fireworks using the Consumer Product Safety Commission’s National Electronic Injury Surveillance System (NEISS). Methods The NEISS database was queried between 2011 and 2017 for all injuries of the upper extremity (from shoulder to fingertip) associated with fireworks. There were 806 unique cases, yielding a total weighted estimate of 31,430 national cases presenting to emergency departments in the United States during this time frame. National estimates, standard errors, and 95% confidence intervals were calculated using parameters provided by the NEISS database. Significance of trends was determined using adjusted Wald tests, for which P values less than .05 were considered significant. Results The weighted estimate was 4,490 yearly cases from 2011 until 2017. Trend analysis did not show a significant change in the number of yearly cases during that time frame. Most injuries (62%) occurred around June 27 until July 11. Nearly 50% of those injured were aged 10 to 29 years and were male. Fireworks with low pyrotechnic content such as sparklers, snakes, and poppers resulted in 26% of injuries. Although 83% of patients were treated and released from the emergency department, other injuries were more severe, with a 4.5% rate of amputation, 7% rate of hospital admission, and 8% rate of transfer to another hospital. Conclusions Fireworks injuries to the hand and upper extremity continue to represent a serious burden of disease to the United States population and the health care system. Increased awareness, legislation, and targeted public education about the dangers of fireworks should be considered ways to reduce the incidence of these injuries.

Implementation of machine learning algorithms for detecting missing radioactive material

The detection of missing radioactive material is an important capability for safeguards measurements. Gamma ray signatures provide sample information, but interpretation is complicated by measurement environments. To determine if machine learning is a viable analysis option, three algorithms are applied to gamma ray detection data to assess their success at identifying missing sources. Preliminary results demonstrate that these algorithms can predict the number and location of missing sources on simple models of spent fuel assemblies. In addition to simulated experiments, a study to investigate if the algorithms can be trained with simulated data and tested on measured data is presented.
Utility of the Pain Medication Questionnaire to predict aberrant urine drug tests: Results from a longitudinal cohort study.

Identifying patients at risk of misusing prescription opioids is a priority. Standardized risk measures exist, but prior research has been limited in an assessment of their utility by a reliance on cross-sectional or retrospective analyses. In this study, the Pain Medication Questionnaire (PMQ), a standardized self-report measure of risk for prescription opioid misuse, was used to predict aberrant urine drug test (UDT) results over the subsequent 24 months. At baseline, participants who were prescribed long-term opioid therapy completed self-report measures assessing pain, function, and quality of life; this also included the PMQ. Medical record data were abstracted for 24 months postbaseline to collect results of UDTs administered during clinical care. Among participants, 12.9% had a UDT result that was positive for a nonprescribed or illicit substance, 18.9% had an aberrant negative UDT result, 3.6% had aberrant positive and negative UDT results, and the remaining 64.6% had expected UDT results. Average PMQ score at baseline did not significantly differ based on participants' type of UDT result over 24 months of follow-up. Participant variables that were significantly associated with a subsequent aberrant positive UDT were higher prescription opioid dose and hazardous alcohol use; those associated with an aberrant negative UDT were lower prescription opioid dose and hazardous alcohol use; no variable was associated with combined positive and negative UDT results. In conclusion, total PMQ score was not predictive of aberrant positive or negative UDT results. More work is needed to identify optimal strategies of screening for risk of aberrant UDT results.

Inscriptions and Silences: Challenges of Bearing Witness at the Gila River Incarceration Camp

Investigations conducted at the Gila River Incarceration Camp are a recent addition to the body of Japanese diaspora archaeology, with initial surveys focusing on landscaping features constructed by incarcerees. However, there remain difficulties in associating most landscaping features with their constructors, with exceptions of the few that have names inscribed. Furthermore, taking a diasporic approach to the incarcerated community materials highlights the diversity of identities present. In this article I discuss some of these challenges and the ambiguities which remain by exploring the ambivalence surrounding inscriptions and the populations which remain silenced by the archive.
Langtry Falls Expansion Plan

It was generally accepted that the weighted average cost of capital (WACC) for a company reflected an appropriate hurdle rate (minimum return or benchmark) for that company's investments. But a WACC for Langtry Falls could not be calculated because the company did not have publicly traded stock, a critical source of one input to the calculation. However, the benchmark for publicly traded competing companies would be meaningful to Langtry—these companies were facing the same underlying risks and competing under the same economic conditions. An average of the industry WACCs would be a defensible and informative benchmark for Langtry. Excerpt UVA-F-1804 Jul. 25, 2018 Langtry Falls Expansion Plan Roxanna Garner had spent a decade transforming Langtry Falls (Langtry) from the small regional equestrian-leather-goods company her grandmother had founded to a fast-growing, high-end leather-fashions business. The shift in focus from chaps and bridles to handbags and device cases had not been difficult. Many of Langtry's suppliers spanned both worlds, and the workers who manufactured Langtry branded goods in its Texas studio embraced the shift in output. Furthermore, the focus on quality and artisanship that had established Langtry's original reputation was a great selling point and differentiator in the fashion business. The real struggle was the shift in competition—the equestrian-goods market was fragmented, and reputation was built regionally by word of mouth, whereas Langtry now competed in a space dominated by large global brands that spent heavily on production efficiencies and advertising. Langtry's history and future were very much on Garner's mind when she sat down in summer 2017 to consider a major expansion in its production facilities. Over the last six years, the company had been growing steadily, at times even briskly, despite a weak economy both locally and globally. The planned expansion was intended to position the company to handle anticipated growth in its most successful self-manufactured product lines. These were, however, exactly the product lines that competed most directly with the major luxury brands, and price competition was fierce. Yet despite that competition, Garner was quite certain that Langtry would perform well and achieve the returns she expected from the expansion investment. What troubled her was whether those returns would be sufficient to generate support for the expansion among Langtry's board of directors. That debate, she was certain, would come down to establishing the right benchmark. Langtry Market . . .
Diverse Roles of Akt in T cells

Akt kinases translate various external cues into intracellular signals that control cell survival, proliferation, metabolism and differentiation. This review discusses the requirement for Akt and its targets in determining the fate and function of T cells. We discuss the importance of Akt at various stages of T cell development including β-selection during which Akt fulfills the energy requirements of highly proliferative DN3 cells. Akt also plays an integral role in CD8 T cell biology where its regulation of Foxo transcription factors and mTORC1 metabolic activity controls effector versus memory CD8 T cell differentiation. Finally, Akt promotes the differentiation of naive CD4 T cells into Th1, Th17 and Tfh cells but inhibits the development of Treg cells. We also highlight how modulating Akt in T cells is a promising avenue for enhancing cell-based cancer immunotherapy.
