Loss and Efficiency Analysis of BLDC Motor and Universal Motor by Mathematical Modelling in the Mixer Grinder
Authors: Nayak Deekshitha S , Shivarudraswamy R. 
Published: September 2021

AbstractThe typical mixer grinders are universal motor, which operates on alternating current supply because of the higher starting torque characteristics and easy speed control. The absence of brushes in the Brushless DC (BLDC) motor and noise reduction improves its life and makes it perfectly suited for mixer grinder. The mathematical modelling and experimental demonstration of a conventional universal motor and proposed simulated model of BLDC motor was analysed using the MATLAB/Simulink. The loss and efficiency analysis of the permanent magnet BLDC and universal motor in the application of a mixer grinder are presented in this paper.

Published: September 2021

AbstractThe value chain refers to the source of competition to facilitate organizations to maximize and sustain value for their consumers. Value chain flexibility is necessary to build sustainable initiatives in addressing ambiguity. In the literature, there is a lack of framework to highlight the challenges to sustainable initiatives in value chain flexibility. This study fills this research gap by suggesting a framework for challenges to sustainable initiatives in value chain flexibility. In this study, thirteen potential challenges to sustainable initiatives in value chain flexibility are identified and an integrated model is developed. It adopts the modified Total Interpretive Structure Model and the Cross-Impact Matrix Multiplication Applied to Classification methodology. The mixed approach is used as the modified Total Interpretive Structure Model organizes the binary interactions among the challenges, while Cross-Impact Matrix Multiplication Applied to Classification analysis organizes specific precise assessments of the driving power and dependence of the challenges. The results of the study reflect that (i) lack of supplier commitment to sustainable products and (ii) lack of knowledge toward sustainability in value chains are the challenges that achieved the highest driving power. The challenge ‘inadequate communication among the suppliers in the value chain’ is at the highest level in the analysis. The proposed framework could help government and non-government bodies to formulate policies to efficiently address challenges to sustainable initiatives in value chain flexibility.

Published: September 2021

AbstractThe wearable sensors have recently attracted considerable attentions as communication interfaces through the information perception, decoding, and conveying process. However, it is still challenging to obtain a sensor that can convert detectable signals into multiple outputs for convenient, efficient, cryptic, and high-capacity information transmission. Herein, we present a capacitive sensor of magnetic field based on a tilted flexible micromagnet array (t-FMA) as the proposed interaction interface. With the bidirectional bending capability of t-FMA actuated by magnetic torque, the sensor can recognize both the magnitude and orientation of magnetic field in real time with non-overlapping capacitance signals. The optimized sensor exhibits the high sensitivity of over 1.3 T−1 and detection limit down to 1 mT with excellent durability. As a proof of concept, the sensor has been successfully demonstrated for convenient, efficient, and programmable interaction systems, e.g., touchless Morse code and Braille communication. The distinguishable recognition of the magnetic field orientation and magnitude further enables the sensor unit as a high-capacity transmitter for cryptic information interaction (e.g., encoded ID recognition) and multi-control instruction outputting. We believe that the proposed magnetic field sensor can open up a potential avenue for future applications including information communication, virtual reality device, and interactive robotics.

Abstract
Phase pure perovskite (1-x)Bi1/2Na1/2TiO3 – xBi1/2K1/2TiO3 (BNKT) thin films were successfully prepared via an inverse mixing order chemical solution deposition method and the impact of process conditions on film properties were observed. Process conditions evaluated included crystallization temperature and time, ramp rate, pyrolysis temperature, and cation excess. Properties measured included crystal structure, dielectric constant, dielectric loss, piezoelectric response, and ferroelectric response. A few notable trends were observed. A subtle impact on piezoelectric response was observed in films prepared using different ramp rates: 100 C per second films (d33,f = 60 ± 5 pm/V at 1 kHz), 75 °C per second films (d33,f = 55 ± 5 pm/V) and 150 C per second films (d33,f = 50 ± 5 pm/V). Films prepared using a 75 °C per second ramp rate displayed slightly higher dielectric loss (tan δ = 0.09 at 1 kHz) than films prepared using a 100 °C per second ramp rate (tan δ = 0.07 at 1 kHz) or 150 °C per second ramp rate (tan δ = 0.05 at 1 kHz). Pyrolysis temperatures greater than 350 °C are necessary to burn off organics and maximize film dielectric constant. Dielectric constant increased from 450 ± 50 at 1 kHz to 600 ± 50 at 1 kHz by increasing pyrolysis temperature from 300 to 400 °C. Excess cation amounts (for compositional control) were also evaluated and it was found films with higher amounts of Na and K excess compared to bismuth excess displayed an increase in d33,f of about 10 pm/V compared to films prepared with equivalent Bi and Na and K excess amounts.

Published: September 2021

AbstractEthiopia is renowned for its cultural and biological diversity and covers an important share of lion habitat in Africa, providing connectivity between East and Central Africa. The aim of this study was to investigate the status of lions and human–lion conflict in several protected areas of Ethiopia and to present an overview on lion distribution nationally. We used call-ups and semi-structured interviews with 809 randomly selected pastoralists to investigate human–lion conflict and pastoralist perceptions towards lions in five priority sites and collected further anecdotal information for all other known or possible lion range. We had chance encounters with six lions, but we observed no lion responses to the call-ups. We recorded 145 spotted hyaena and 23 jackal responses at, respectively, 25 and 13 of the 46 call-up stations. Overall, respondents viewed lions as dangerous carnivores, but nonetheless responded that lions should be present regionally, preferably in restricted areas. Most respondents disagreed that the killing of lions should be allowed, but we note that a small minority strongly agreed to killing. A large majority of respondents agreed that more people need to be given information about lions. Respondents mentioned spotted hyaena and leopard as the main predators on all livestock followed by jackal (shoats) and lion (mainly cattle). The impact of depredation on livestock mortality was nearly twice that of disease. Our results strongly suggest that lion densities are low and may have substantially decreased in Awash, Nechisar, Chebera-Churchura, and Mago National Parks and in Kaffa Biosphere Reserve due to conflict, habitat loss and especially ineffective protection. Anecdotal information suggests that lions are widespread but rare and that there is no stronghold in Ethiopia. Considering the unique evolutionary background of Ethiopia as the bridge between Central and East African lion populations, and the significant role of the lion in Ethiopian history and culture, we argue that more emphasis should be given to the protection of prioritized lion populations.

AbstractIntroduction:Ensuring equitable access to health care is a widely agreed-upon goal in medicine, yet access to care is a multidimensional concept that is difficult to measure. Although frameworks exist to evaluate access to care generally, the concept of “access to genomic medicine” is largely unexplored and a clear framework for studying and addressing major dimensions is lacking.Methods:Comprised of seven clinical genomic research projects, the Clinical Sequencing Evidence-Generating Research consortium (CSER) presented opportunities to examine access to genomic medicine across diverse contexts. CSER emphasized engaging historically underrepresented and/or underserved populations. We used descriptive analysis of CSER participant survey data and qualitative case studies to explore anticipated and encountered access barriers and interventions to address them.Results:CSER’s enrolled population was largely lower income and racially and ethnically diverse, with many Spanish-preferring individuals. In surveys, less than a fifth (18.7%) of participants reported experiencing barriers to care. However, CSER project case studies revealed a more nuanced picture that highlighted the blurred boundary between access to genomic research and clinical care. Drawing on insights from CSER, we build on an existing framework to characterize the concept and dimensions of access to genomic medicine along with associated measures and improvement strategies.Conclusions:Our findings support adopting a broad conceptualization of access to care encompassing multiple dimensions, using mixed methods to study access issues, and investing in innovative improvement strategies. This conceptualization may inform clinical translation of other cutting-edge technologies and contribute to the promotion of equitable, effective, and efficient access to genomic medicine.
Detecting SARS-CoV-2 Orf3a and E ion channel activity in COVID-19 blood samples
Authors: Yu Han-Gang , Sizemore Gina , Smoot Katy , Perrotta Peter 
Published: September 2021

Abstract

Background:
SARS-CoV-2 has been found in the heart of COVID-19 patients. It is unclear how the virus passes from the upper respiratory tract to the myocardium. We hypothesized that SARS-CoV-2 is present in the blood of COVID-19 infected patients, spreading to other organs such as heart.

Methods:
We targeted two viroporins, Orf3a and E, in SARS-CoV-2. Orf3a and E form non-voltage-gated ion channels. A combined fluorescence potassium ion assay with three channel modulators (4-aminopyridine, emodin-Orf3a channel blocker, and gliclazide-E channel blocker) was developed to detect SARS-CoV-2 Orf3a/E channel activity. In blood samples, we subtracted the fluorescence signals in the absence and presence of emodin/gliclazide to detect Orf3a and E channel activity.

Results:
In lentivirus-spiked samples, we detected significant channel activity of Orf3a/E based on increase in fluorescence induced by 4-aminopyridine, and this increase in fluorescence was inhibited by emodin and gliclazide. In 18 antigen/PCR-positive samples, our test results found 15 are positive, demonstrating 83.3% concordance. In 24 antigen/PCR-negative samples, our test results found 21 are negative, showing 87.5% concordance.

Conclusions:
We developed a cell-free test that can detect Orf3a/E channel activity of SARS-CoV-2 in blood samples from COVID-19-infected individuals, confirming a hypothesis that the virus spreads to the heart via blood circulation.

Published: September 2021

ABSTRACTA setup for ion-laser interaction was coupled to the state-of-the-art AMS facility VERA five years ago and its potential and applicability as a new means of isobar suppression in accelerator mass spectrometry (AMS) has since been explored. Laser photodetachment and molecular dissociation processes of anions provide unprecedented isobar suppression factors of >1010 for several established AMS isotopes like 36Cl or 26Al and give access to new AMS isotopes like 90Sr, 135Cs or 182Hf at a 3-MV-tandem facility. Furthermore, Ion-Laser InterAction Mass Spectrometry has been proven to meet AMS requirements regarding reliability and robustness with a typical reproducibility of results of 3%. The benefits of the technique are in principle available to any AMS machine, irrespective of attainable ion beam energy. Since isobar suppression via this technique is so efficient, there often is no need for any additional element separation in the detection setup and selected nuclides may even become accessible without accelerator at all.
HAZOR EB III CITY ABANDONMENT AND IBA PEOPLE RETURN: RADIOCARBON CHRONOLOGY AND ITS IMPLICATIONS
Authors: Lev Ron , Bechar Shlomit , Boaretto Elisabetta 
Published: September 2021

ABSTRACTTel Hazor is one of only a few sites in Israel where remains of the Intermediate Bronze Age (IBA) in the second half of the 3rd millennium BC were found on top of Early Bronze III (EB III) city remains. A probe excavation was held at Hazor in 2017 to explore the chronological relation between the EB III and the IBA occupation. The radiocarbon (14C) absolute dates generated from this probe excavation show that following the EB III city demise, the site was abandoned for up to a few hundred years before it was resettled in the IBA.14C dates obtained from the last level of the EB III city are well before 2500 BCE, fully aligned with the recent “High Chronology” for the EBA in the southern Levant. The excavation also produced dates associated with IBA “Black Wheel-Made Ware” vessels, which were found in large numbers at Hazor.
‘DAY WATCH’ OR BAYWATCH? A NOTE ON ΗΜΕΡΟΣΚΟΠΟΣ (AR.LYS. 849)
Authors: Janse Mark 
Published: September 2021

AbstractThis article argues thatἡμεροσκόποςatLys. 849 constitutes a pun based on iotacism, a well-known feature of female speech in fifth-century Athens aptly illustrated by Socrates in Plato'sCratylus. By describing herself asἡμεροσκόπος‘day watch’ pronounced asἱμεροσκόπος‘lust watch’, Lysistrata perverts the military term associated with the occupation-plot to a sexually charged word associated with the strike-plot. Its use would be very appropriate in a scene in which theφαλληφόριαof the men (not just Cinesias’ but later on also the Spartan herald's and the Spartan and Athenian delegates’) become the subject of aφαλλοσκοπίαby the women (not just Lysistrata but later on also the chorus of women) and perforce also by the onlooking audience. Additional contemporary evidence from orthographic mistakes made by schoolboys suggests that Athenian elite women of the late fifth century were the avant-garde of socially prestigious innovations such as iotacism, which would definitively catch on with the male population in the fourth century and change the face of Greek phonology forever.
From Legislation to Everyday Practices in Guatemala's Violence against Women Courts
Authors: Beck Erin , Stephen Lynn 
Published: September 2021

AbstractWe explore how formal mandates associated with Guatemala's 2008 ‘Law against Femicide and Other Forms of Violence against Women’ and with specialised violence against women (VAW) courts have encountered significant challenges due to state-imposed constraints. Drawing on courtroom observations, analyses of case files, and interviews, we find that while formal mandates incorporated feminist understandings of violence against women, which were often internalised among court officials, in daily practice specialised courts reproduced tendencies to depict violence as interpersonal, fragment people's experiences and enact narrow forms of justice that do not incorporate the full intent of the 2008 VAW Law and institutions intended to support it. This case study thus illuminates how and why legal solutions alone are not sufficient to reduce gender-based violence and feminicide, particularly in the face of uneven and openly hostile challenges posed by governments.
Aberrant adapting of beliefs under stress: a mechanism relevant to the formation of paranoia?
Authors: Krkovic Katarina , Nowak Ulrike , Kammerer Mathias K. , Bott Antonia , Lincoln Tania M. 
Published: September 2021

AbstractBackgroundDifficulties in the ability to adapt beliefs in the face of new information are associated with psychosis and its central symptom – paranoia. As cognitive processes and psychotic symptoms are both known to be sensitive to stress, the present study investigated the exact associations between stress, adapting of beliefs [reversal learning (RL), bias against disconfirmatory evidence (BADE), and jumping to conclusions (JTC)] and paranoia. We hypothesized that paranoia would increase under stress and that difficulties in adapting of beliefs would mediate or moderate the link between stress and paranoia. Furthermore, we hypothesized that the investigated effects would be strongest in the group of individuals diagnosed with a psychotic disorder.MethodsWe exposed 155 participants (38 diagnosed with a psychotic disorder, 40 individuals with attenuated psychotic symptoms, 39 clinical controls diagnosed with an obsessive-compulsive disorder, and 38 healthy controls) to a control condition and a stress condition, in which we assessed their levels of paranoia and their ability to adapt beliefs. We applied multilevel models to analyze the data.ResultsParanoia was higher in the stress condition than in the control condition, b = 1.142, s.e. = 0.338, t(150) = 3.381, p < 0.001. RL, BADE, and JTC did not differ between conditions and did not mediate or moderate the association between stress and paranoia (all ps > 0.05).ConclusionsThe results support the assumption that stress triggers paranoia. However, the link between stress and paranoia does not seem to be affected by the ability to adapt beliefs.
Through the Mirror of CCP History: Four Perspectives
Authors: Thornton Patricia M. 
Published: September 2021

Perhaps the most oft-quoted part of Xi Jinping's defiant 1st July speech marking the Party's centenary was his warning than any external forces attempting to “bully, oppress or subjugate” China will “dash their heads against the Great Wall of steel built with the flesh and blood of more than 1.4 billion Chinese people.” Foreign news organizations covering the ceremony also noted the “visual trick” of Xi's donning of a grey Mao suit identical to the one worn by the Great Helmsman in the portrait that hangs on Tiananmen, just feet below the rostrum from which Xi delivered his address; others doubted the functional significance of the five identical microphones, ascribing to them a very different significance. Xi's repeated references to the importance of Party history, however, drew far less attention in the Western press, although Xi gravely warned a cheering and flag-waving audience of more than 70,000 that while the CCP's original mission “is easy to define, ensuring that we stay true to this mission is a more difficult task.”
By learning from history, we can understand why powers rise and fall. Through the mirror of history, we can find where we currently stand and gain foresight into the future. Looking back on the Party's 100-year history, we can see why we were successful in the past and how we can continue to succeed in the future.Indeed, in the months leading up to the centennial celebration, the Party launched a comprehensive campaign requiring CCP members to study the Party's past closely; A Short History of the Chinese Communist Party was revised and updated, eliminating a previous discussion of the consequences of the Great Leap Forward, which had concluded with the open acknowledgement that “This bitter historical lesson shouldn't be forgotten.” Also expunged was a frank evaluation of the excesses of the Cultural Revolution, which was replaced with an account that restricted its focus to highlighting various industrial, technological and diplomatic advances made over the course of that period, without acknowledging the social and political turmoil that accompanied those developments.
Polygamy, the Commodification of Women, and Underdevelopment
Authors: Seligson Daniel , McCants Anne E. C. 
Published: September 2021

AbstractFamily systems shape social institutions, yet they are rarely considered in histories of economic development. In this article, we show that a suite of social conventions—such as age gaps at marriage, bride price, sequestration, and discrimination and violence against women—are overrepresented in polygamous societies as compared to monogamous societies. This dichotomy can be explained on the grounds that polygamy produces a chronic scarcity of marriageable females. We argue that this suite, which we call gamos and which we quantify by two different methods, has demonstrably significant consequences for social, institutional, and economic development.
