Ground-generation airborne wind energy design space exploration

Abstract. While some Airborne Wind Energy System (AWES) companies aim at small-scale, temporary or remote off-grid markets, others aim to integrate utility-scale, multi-megawatt AWES into the electricity grid. This study investigates the scaling effects of single-wing, ground-generation AWESs from small to large-scale systems, subject to realistic 10-minute, onshore and offshore wind conditions derived from the numerical mesoscale weather research and forecasting (WRF) model. To reduce computational cost, wind velocity profiles are grouped into k = 10 clusters using k-means clustering. Three representative profiles from each cluster are implemented into a nonlinear AWES optimal control model, to determine power-optimal trajectories, system dynamics, as well as instantaneous and cycle-average power. We compare the performance of three different aircraft masses and two sets of nonlinear aerodynamic coefficients for each aircraft size, with wing areas ranging from 10 m2 to 150 m2. We predict size and weight-dependent, optimal AWES power curves, annual energy production (AEP) and capacity factor (cf). Tether impacts, such as power losses associated with tether drag and the tether contribution to total system mass are quantified. Furthermore, we estimate a minimum average cycle-average lift to weight ratio, above which ground-generation AWES can operate, to explore the viable AWES mass budget.
Spray‐Dried TiO2(B)‐Containing Photocatalytic Glass‐Ceramic Nanobeads

Glass‐ceramic nanospheres of molar composition 0.83 SiO2 · 0.17 TiO2 are produced by the sol‐gel spray‐drying method followed by controlled heat treatments up to 1200 °C. TiO2(B) and anatase nanocrystals are precipitated in the glassy matrix: the latter phase gradually predominates with increasing ceramization temperature and time, in parallel to an overall increase in crystal sizes. The nanospheres exhibit evident photocatalytic activity under UV‐A irradiation, especially at annealing stages involving a comparatively higher amount of TiO2(B) and smaller crystals. The occurrence of TiO2(B) in this simplified binary glass‐ceramic material underlines the key role of this phase in the dynamics of crystallizing TiO2‐bearing silicate melts.
How Do Face Consciousness and Public Self-Consciousness Affect Consumer Decision-Making?

Many individual differences affect consumers in the decision-making process (i.e., what to purchase; when to purchase). Face consciousness and public self-consciousness affect when in the fashion life cycle consumers decide to purchase, as well as what to purchase. Both face consciousness and public self-consciousness are concerned with consciousness (i.e., awareness; mindfulness) and both depend on social comparison processes. But the motivation underlying the social comparisons is different: with face consciousness, social comparisons yield appraisals of prestige and social status; with public self-consciousness, social comparisons yield assessments of situational appropriateness. The purpose of this study was to examine links among face consciousness; public self-consciousness; brand prestige; self-expressive brand (inner; social), and fashion leadership. Participants were 221 university students who completed a questionnaire. Descriptive statistics, Cronbach’s alpha reliability, and multivariate/univariate analysis of variance (M/ANOVA) were conducted to analyze data. Results showed that face consciousness and public self-consciousness similarly affected ratings of the social self-expressive brand. However, face consciousness (but not public self-consciousness) influenced ratings of brand prestige and inner self-expressive brand. Public self-consciousness (but not face consciousness) influenced fashion leadership. Thus, while face consciousness and public self-consciousness are both concerned with consciousness, they independently influence consumer decision-making in different ways. Theoretical and practical implications are provided.
Inequality and Real Income Growth for Middle- and Low-income Households across Rich Countries in Recent Decades

This paper places what has happened to income inequality in rich countries over recent decades alongside trends in median and low incomes in real terms, taken as incomplete but valuable indicators of the evolution of living standards for “ordinary working families” and the poor. The findings demonstrate first just how varied country experiences have been, with some much more successful than others in generating rising real incomes around the middle and toward the bottom of the distribution. This variation is seen to be only modestly related to the extent to which income inequality rose, which itself is more varied across the rich countries than is often appreciated. The extent to which economic growth is transmitted to the middle and lower parts of the distribution is seen to depend on a range of factors of which inequality is only one. Sources of real income growth around the middle have also varied across countries, though transfers are consistently key toward the bottom. The diversity of rich country experiences should serve as an important corrective to a now-common “grand narrative” about inequality and stagnation based on the experience of the USA.
A guide for the pharmacist's role in insulin pump management during transitions of care

In the United States, approximately 12% of the adult population has a diagnosis of diabetes mellitus (DM). Persons with DM are at a higher risk of microvascular and macrovascular complications, as well as hospitalizations, compared with the general population. Over the years, technology for diabetes management has evolved as approximately 350 000 patients are using insulin pump therapy to manage DM. Insulin pump therapy has been shown to improve glycemic control and lower the risk of safety events, such as hypoglycemia. Some studies have shown high compliance with an insulin pump policy among staff members during a hospitalization for a patient with an insulin pump. Other studies have shown improved glycemic control during hospitalization for patients who were managed on an insulin pump from an outpatient endocrinology clinic prior to admission. However, none of the studies involved pharmacy‐ or pharmacist‐led service for insulin pump management during transitions of care. Therefore, we defined the responsibilities of clinical pharmacists, in various roles, regarding insulin pump management in transitions of care. The purpose of this paper is to summarize current evidence for continuous subcutaneous insulin infusion (CSII) in transitions of care, including the use of insulin pumps in the hospital. Opportunities for a pharmacist's role in policies and procedures are also outlined, along with training of clinical pharmacists in this area of practice.
Outcomes of Patients With Hematologic Malignancies Who Received Inpatient Palliative Care Consultation

PURPOSE: Palliative care (PC) plays an established role in improving outcomes in patients with solid tumors, yet these services are underutilized in hematologic malignancies (HMs). We reviewed records of hospitalized patients with active HM to determine associations between PC consultation and length of stay, intensive care unit stay, 30-day readmission, and 6-month mortality compared with those who were not seen by PC. METHODS: We reviewed all oncology admissions at our institution between 2013 and 2019 and included patients with HM actively on treatment, stratified by those seen by PC to controls not seen by PC. Groups were compared using Wilcoxon rank-sum, chi-square, and Fisher's exact tests on the basis of the type and distribution of data. Multiple logistic regression models with stepwise variable selection methods were used to find predictors of outcomes. RESULTS: Three thousand six hundred fifty-four admissions were reviewed, among which 370 unique patients with HM were included. Among these, 102 (28%) patients saw PC, whereas the remaining 268 were controls with similar comorbidities. When compared with controls, PC consultation was associated with a statistically significant reduction in 30-day readmissions (16% v 27%; P = .024), increased length of stay (11.5 v 6 days; P < .001), increased intensive care unit admission (28% v 9%; P < .001), and increased 6-month mortality (67% v 15%; P < .001). These data were confirmed in multivariable models. CONCLUSION: In this retrospective study, more than two thirds of patients with HM did not receive PC consultation despite having similar comorbidities, suggesting that inpatient PC consultation is underutilized in patients with HM, despite the potential for decreased readmission rates. Inpatient palliative care correlated with lower readmission, and greater length of stay and mortality in hematologic malignancies.
Investigating the effect of learning management system transition on administrative staff performance using task-technology fit approach

Article history: Received: July 10, 2020 Received in revised format: October 18 2020 Accepted: October 25, 2020 Available online: October 25, 2020 Educational institutions are adopting learning management systems (LMS) to facilitate teaching and learning processes. During the last few years, many Universities have started upgrading their existing LMS by shifting to advance LMS. This shift requires students, academic as well as administrative staff to get acquainted with the functioning of the new system at the earliest, as any change in the system may impact their performance. The transition from old to new LMS requires time and affects the performance of users, especially administrative staff performance. The present study tries to investigate the effect of the transition on the performance of the administrative staff. The task-technology fit (TTF) model was adopted as the theoretical framework for the study. The data analysis was done using the PLS-SEM, to test the hypothesized relationships. The findings of the study confirm that mere usage of the new technology did not improve the performance rather, the task and technology characteristics need to be coordinated appropriately. © 2021 by the authors; licensee Growing Science, Canada

Cerebral Ischemia is Associated With Corneal Nerve Loss and Brain Atrophy in Mild Cognitive Impairment and Dementia

BackgroundThe prevalence of cerebral ischemia increases with age and is a risk factor for cognitive impairment and dementia. This study assessed the association of brain ischemic lesions with the severity of neurodegeneration utilizing brain volumetric MRI and corneal confocal microscopy (CCM) in patients with mild cognitive impairment (MCI) and dementia.MethodsSubjects with MCI and dementia without diabetes underwent cognitive screening, CCM, assessment of ischemic lesions and quantitative brain MRI.ResultsOf 63 subjects with MCI (n=44) and dementia (n=19), 11 had no ischemia, 32 had subcortical ischemia and 20 had both cortical and subcortical ischemia. Subjects with MCI and dementia had comparable percentage of cerebral ischemia (P=0.25). Global cognitive function was significantly impaired in subjects with both cortical and subcortical ischemia (P<0.05) but not in those with subcortical ischemia (P=0.10) compared to those without ischemia. Corneal nerve fiber density (CNFD)(P<0.01), branch density (CNBD) (P<0.05) and fiber length (CNFL) (P<0.01) were significantly lower in subjects with both cortical and subcortical ischemia compared to those without ischemia and CNFD (P<0.05), CNBD (P<0.05) and CNFL (P<0.05) were significantly lower in subjects with both cortical and subcortical ischemia compared to those with subcortical ischemia. In subjects with both cortical and subcortical ischemia whole brain (P<0.01) and hippocampal volume (P<0.001) were significantly lower and ventricle volume was higher (P<0.05) compared to those without ischemia and hippocampal volume (P<0.01) was lower and ventricle volume was higher (P<0.01) in subjects with both cortical and subcortical ischemia compared to those with subcortical ischemia.ConclusionsThe presence of cortical and subcortical ischemia is associated with cognitive impairment, corneal nerve loss and brain atrophy in patients with MCI and dementia.
Energetic Proton Acceleration Associated With Io's Footprint Tail

Observations of energetic charged particles associated with Io's footprint (IFP) tail, and likely within or very near the Main Alfvén Wing, during Juno's 12th perijove (PJ) crossing show evidence of intense proton acceleration by wave‐particle heating. Measurements made by Juno/JEDI reveal proton characteristics that include pitch angle distributions concentrated along the upward loss cone, broad energy distributions that span ~50 keV to 1 MeV, highly structured temporal/spatial variations in the particle intensities, and energy fluxes as high as ~100 mW/m2. Simultaneous measurements of the plasma waves and magnetic field suggest the presence of ion cyclotron waves and transverse Alfvénic fluctuations. We interpret the proton observations as upgoing conics likely accelerated via resonant interactions with ion cyclotron waves. These observations represent the first measurements of ion conics associated with moon‐magnetosphere interactions, suggesting energetic ion acceleration plays a more important role in the IFP tail region than previously considered.
Airborne polycyclic aromatic hydrocarbons in a medium-sized city affected by preharvest sugarcane burning and inhalation risk for human health

Polycyclic aromatic hydrocarbons (PAHs) in air were measured in a municipality where sugarcane plantations are extensive, at three sites, one in the city center and two in rural localities. Twenty-four-hour sampling was done using PS1 PUF samplers from Andersen Instruments Inc., at least 1 day per month per site, from June 2009 to October 2009. The chemical analyses were performed by gas chromatography–mass spectrometry (GC/MS) for the 16 most toxic PAHs. The incremental lifetime cancer risk (ILTR) by inhalation was determined by the Monte Carlo method for the urban population using Crystal Ball software. The total concentration of the 16 PAHs at all sites varied from 6.2 to 65.7 ng m−3, with an average of 25.9 ± 18.2 ng m−3. The average concentrations per site were 14.1 ± 13.0 ng m−3 at rural site B, 20.7 ± 11.5 ng m−3 at rural site A, and 36.1 ± 22.7 ng m−3 at the central site. The cancer risk for infants, children, and adults was approximately 14%, 25%, and 61% of the total IRLT, respectively. The mean (95% upper probability limit [95% UPL]) values were 1.2 × 10−7 (2.2 × 10−7) for infants, 2.2 × 10−7 (4.1 × 10−7) for children, and 8.9 × 10−7 (1.1 × 10−6) for adults. Although the three most abundant PAHs found were phenanthrene, fluoranthene, and pyrene, the three most important contributions to the incremental risk of cancer came from benzo[a]pyrene, benzo[b]fluoranthene, and naphthalene. Compared with the risks in big cities such as São Paulo, this would be low, but not negligible. Analysis of ratios of PAHs according to the literature showed that vehicle exhaust and biomass burning, including sugarcane burning, seem to be the most important contributors to PAH concentrations in the central area of Araraquara City. Implications: The growth of biofuel use worldwide, especially ethanol, together with preharvesting burning practice, is cause of concern with regard to possible health effects, due to increased air pollution levels in cities in regions where sugarcane plantation and processing are intensive. This paper shows that the risk of cancer from PAH inhalation in an urban area surrounded by sugarcane agriculture was of the same order of magnitude as the tolerable risk value of 10−6. As other classical and hazardous pollutants are also present, care should be taken to keep pollution as low as possible to protect human health.
Effects of pulse polarity on nanosecond pulse driven dielectric barrier discharge plasma actuators

Nanosecond pulse driven dielectric barrier discharge plasma actuators are studied in quiescent air using a power supply capable of producing negative and positive polarity waveforms. High voltage pulses are applied to the exposed electrode of typical asymmetric actuator geometry. In addition to polarity, the effects of pulse amplitude, actuator length, and dielectric thickness are also investigated. Schlieren images are used to estimate the relative near surface gas heating, while electrical measurements are acquired simultaneously. Negative polarity pulses develop slightly more energy per unit length for thin dielectrics, while positive polarity is slightly higher for thick dielectrics. In most cases, the difference in per unit length energy produced by positive and negative pulses on equivalent actuators is not outside the measurement uncertainty. Negative polarity pulses are found to produce a stronger pressure wave for a given peak voltage and pulse energy across the test matrix. Results indicate that.
A Unifying Perspective on Transfer Function Solutions to the Unsteady Ekman Problem

The unsteady Ekman problem involves finding the response of the near-surface currents to wind stress forcing under linear dynamics. Its solution can be conveniently framed in the frequency domain in terms of a quantity that is known as the transfer function, the Fourier transform of the impulse response function. In this paper, a theoretical investigation of a fairly general transfer function form is undertaken with the goal of paving the way for future observational studies. Building on earlier work, we consider in detail the transfer function arising from a linearly-varying profile of the vertical eddy viscosity, subject to a no-slip lower boundary condition at a finite depth. The horizontal momentum equations, rendered linear by the assumption of horizontally uniform motion, are shown to transform to a modified Bessel’s equation for the transfer function. Two self-similarities, or rescalings that each effectively eliminate one independent variable, are identified, enabling the dependence of the transfer function on its parameters to be more readily assessed. A systematic investigation of asymptotic behaviors of the transfer function is then undertaken, yielding expressions appropriate for eighteen different regimes, and unifying the results from numerous earlier studies. A solution to a numerical overflow problem that arises in the computation of the transfer function is also found. All numerical code associated with this paper is distributed freely for use by the community.
Microbial analysis and factors associated with contamination of ready-to-eat chili pepper sauce in Buea municipality, Cameroon

Chili peppers sauce is a dietary complement largely consumed in Cameroon. It is consumed in a powder or wet (pepper sauce) form or directly introduced into cooked food. In this study, the microbiological quality of chili pepper sauce used as food complement in the Buea municipality was assessed. The study was an observational and cross-sectional study involving 70 chili pepper sauce samples from food vendors. The samples were cultured on Salmonella-Shigella agar, violet red bile agar, plate count agar and the colonies isolated were enumerated and identified using the Enterosystem 18R. Factors associated with microbial count were identified using a multiple linear regression model. Bacteria isolate from chili pepper sauce were mainly Entrobacter cloacae (31.57%), Citrobacter freundii (15.78%) and Klebsiella pneumonia (15.78%) and other Enterococcal species. Factors associated with bacteria count were: age of the vendor, number of customers served, types of food and food storage conditions (covering, heating, type of storage containers). Chili pepper sauce used as food complement in Buea Municipality were contaminated with Enteric microorganisms and may represents a potential public health hazard to consumers. The presence of these microorganisms from chilli pepper sauce could result from poor handling. Key words: Chili pepper sauce, contamination, enteric bacteria, health hazard.
Mathematical and intelligent modeling of stevia (Stevia Rebaudiana) leaves drying in an infrared‐assisted continuous hybrid solar dryer

Abstract Drying characteristics of stevia leaves were investigated in an infrared (IR)‐assisted continuous‐flow hybrid solar dryer. Drying experiments were conducted at the inlet air temperatures of 30, 40, and 50°C, air inlet velocities of 7, 8, and 9 m/s, and IR lamp input powers of 0, 150, and 300 W. The results indicated that inlet air temperature and IR lamp input power had significant effect on drying time (p < .05). A comparative study was performed among mathematical, Artificial Neural Networks (ANNs), and Adaptive Neuro‐Fuzzy System (ANFIS) models for predicting the experimental moisture ratio (MR) of stevia leaves during the drying process. The ANN model was the most accurate MR predictor with coefficient of determination (R2), root mean squared error (RMSE), and chi‐squared error (χ2) values of 0.9995, 0.0005, and 0.0056, respectively, on test dataset. These values of the ANFIS model on test dataset were 0.9936, 0.0243, and 0.0202, respectively. Among the mathematical models, the Midilli model was the best‐fitted model to experimental MR values in most of the drying conditions. It was concluded that artificial intelligence modeling is an effective approach for accurate prediction of the drying kinetics of stevia leaves in the continuous‐flow IR‐assisted hybrid solar dryer.
