Case-Studies on Green Corrosion Inhibitors
Authors: Ramesh M.
Published: May 2021

Corrosion in metals and its alloys is an inevitable phenomenon but can be controlled by suitable classical methods like process control, cathode protection, surface treating methods, impurity reduction in metals and addition of metals to form alloys. Nevertheless, the employment of corrosion inhibitors is still a noteworthy and simplest of all the above processes in protecting the metals and alloys especially in acidic media. Protection of metals against corrosion not only prevents corrosion but also is beneficial in terms of money loss as far as industrial equipment, surfaces and vessels are concerned. Since the use of organic and inorganic inhibitors are highly discouraged due to their high cost and toxicity, necessity has adequately aroused the development of corrosion inhibitors which are natural and green. Trends, nowadays, focussed in controlling corrosion in various metals and alloys through green corrosion inhibitors consisting of natural elements alone. In contrast to the inorganic inhibitors, green corrosion inhibitors are characterized by biodegradability, low cost and meagre toxicity. Several researchers are now turning themselves towards the research of green inhibitors which are of no threat to humans and the ecosystem. The current discussion is focussed on the fundamentals of corrosion, corrosion inhibition, materials used for it and case studies of green inhibitors used for corrosion control in various conventional and monolithic metals.

Resonant stimulated Raman scattering (SRS) on the 23S-11S forbidden transition of the helium atom (62.6 nm) through the intermediate 23P1 level is considered. The 23S metastable state has the lowest energy in the triplet part of the spectrum (He *), and the 11S state is the ground state. For the density matrix, shortened kinetic equations are derived, which are used to analyze the SRS resonance. Expressions for field broadening and resonance shift are obtained, Doppler broadening is taken into account, and numerical estimates are made.

Vibration-rotation structure of the ν3 band of ClO2 was recorded with a Bruker IFS 125 HR Fourier spectrometer with a resolution of 0.0015 cm–1. Ro-vibrational analysis of the recorded experimental spectrum was made with an improved effective Hamiltonian and developed computer code for ro–vibrational spectra of open–shell free radical molecules including spin–rotation interactions. About 4200 transitions with the maximum values Nmax = 68 and Kamax = 21 belonging to the ν3 band were assigned and subsequently used to determine a set of 13 spectroscopic parameters of the vibrational state under study. The root-mean-square deviation of the results is drms = 2.4 ∙ 10-4 cm-1.

Влияние пространственной дисперсии в металлах на оптические характеристики биметаллических плазмонных наночастиц
Authors: Еремин Ю.А.
Published: May 2021

The problem of diffraction of an electromagnetic plane wave field on a core-shell nanoparticle composed of two plasmon metals is considered. The effect of spatial dispersion in metals on the absorption cross section is investigated on the basis of the Discrete Sources method. Various combinations of core and shell metals: Au@Ag and Ag@Au of spheroidal particles, as well as the effect of elongation and asymmetry of particle geometry on energy absorption are being studied. It was found that taking into account the spatial
dispersion, both in the core and in the shell, leads to a significant decrease in the absorption cross section and a shift of the plasmon resonance to the shorter wavelength region.

BACKGROUND

The incidence of major surgery is on the rise globally, and more than 20% of patients are readmitted to hospital following discharge from hospital. During their hospital stay, patients are monitored for early detection of clinical deterioration, which includes regularly measuring physiological parameters such as blood pressure, heart rate, respiratory rate, temperature, and pulse oximetry. This monitoring ceases upon hospital discharge, as patients are deemed clinically stable. Monitoring after discharge is relevant to detect adverse events occurring in the home setting and can be made possible through the development of digital technologies and mobile networks. Smartwatches and other technological devices allow patients to self-measure physiological parameters in the home setting, and Bluetooth connectivity can facilitate the automatic collection and transfer of this data to a secure server with minimal input from the patient.

OBJECTIVE

This paper presents the protocol for the DREAMPath (Domiciliary Recovery After Medicalization Pathway) study, which aims to measure compliance with a multidevice remote monitoring kit after discharge from hospital following major surgery.

METHODS

DREAMPath is a single-center, prospective, observational, cohort study, comprising 30 patients undergoing major intracavity surgery. The primary outcome is to assess patient compliance with wearable and interactive smart technology in the first 30 days following discharge from hospital after major surgery. Secondary outcomes will explore the relation between unplanned health care events and physiological data collected in the study, as well as to explore a similar relationship with daily patient-reported outcome measures (Quality of Recovery–15 score). Secondary outcomes will be analyzed using appropriate regression methods. Cardiopulmonary exercise testing data will also be collected to assess correlations with wearable device data.

RESULTS

Recruitment was halted due to COVID-19 restrictions and will progress once research staff are back from redeployment. We expect that the study will be completed in the first quarter of 2022.

CONCLUSIONS

Digital health solutions have been recently made possible due to technological advances, but urgency in rollout has been expedited due to COVID-19. The DREAMPath study will inform readers about the feasibility of remote monitoring for a patient group that is at an increased risk of acute deterioration.

Background and objectives

ANCA-associated vasculitis is extremely rare in children. We report the clinicopathologic features, long-term outcomes, and prognostic factors of a large pediatric cohort of patients with ANCA-associated kidney vasculitis.

Design, setting, participants, & measurements

This retrospective study included 85 consecutive patients with kidney biopsy specimen–proven ANCA-associated vasculitis from tertiary referral centers in Italy and Canada. Kidney biopsy specimens were categorized as focal, crescentic, sclerotic, or mixed, according to the Berden classification. The prognostic significance of baseline clinical, laboratory, and histologic findings was analyzed with respect to kidney failure or CKD stage 3–5/kidney failure.

Results

A total of 53 patients had microscopic polyangiitis (62%), and 32 had granulomatosis with polyangiitis (38%). Rapidly progressive GN was the most frequent presentation (39%); a third of the patients also had nephrotic-range proteinuria. Kidney biopsy specimens were classified as focal in 21% of the patients, crescentic in 51%, sclerotic in 15%, and mixed in 13%. Remission-induction therapies included cyclophosphamide in 78% of patients. A total of 25 patients (29%) reached kidney failure. The median (interquartile range) time to kidney failure or last follow-up was 35 (6–89) months in the whole cohort, and 73 (24–109) months among the patients who did not reach this outcome. Patients whose biopsy specimens showed sclerotic histology had significantly shorter kidney survival (hazard ratio, 11.80; 95% confidence interval, 2.49 to 55.99) and survival free of CKD stage 3–5 (hazard ratio, 8.88; 95% confidence interval, 2.43 to 32.48), as compared with those with focal/mixed histology. Baseline eGFR, low serum albumin, hypertension, central nervous system complications, and sclerotic histology, which reflected severe kidney involvement, were associated with both kidney failure and CKD stage 3–5/kidney failure at unadjusted analysis; no independent prognostic factors emerged at multivariable analysis.

Conclusions

Children with ANCA-associated kidney vasculitis often have aggressive presentation; a third of such children progress to kidney failure and this usually occurs early during follow-up. A severe clinical presentation is associated with the development of CKD or kidney failure.

Haute couture giysilerin, insan ölçülerinin 1/3 oranında küçültülmüş prototiplerini giyen ve on sekizinci yüzyılda ‘modanın elçileri’ olarak tanımlanan moda bebekleri; 1945 yılında Théâtre de la Mode gezici sergisinin minyatür sahnesinde moda tasarımını dramatik sanatlar ve plastik sanatlarla birleştiren, haute couture zanaatını kültürel bir alana taşıyan öncü bir sergileme biçiminde yeniden ortaya çıkmışlardır. Bu araştırmada moda bebekleri ile minyatür haute couture sergileri düzenlemek fikrinden ilham alan Two Centuries of French Fashion Elegance (1949-1950), The House of Viktor & Rolf (2008), Le Petit Théâtre Dior (2014-2016) gezici sergileri incelenmektedir. Çalışmada, bu üç sergide tasarımcıların moda kreasyonlarını sanatsal biçimde nasıl sundukları anlatılmaktadır. Sergilerin yansıttıkları moda tarihi dönemlerini gerçek malzemeleri, teknikleri ile görsel olarak betimleyen belgeler olma niteliği kazandıklarını ve bu bağlamda moda bebeklerin birer maddi kültür öğesine dönüştüklerini açıklamak hedeflenmektedir. Minyatür haute couture sergileri konusunun incelenmesinin, Türkçe literatüre katkı sağlayacağı ve ulusal moda tasarım çalışmalarının sergilenme biçimlerine sanatsal bir bakış açısı kazandırabileceği düşünülmektedir.

Versatile Super-Sensitive Metrology Using Induced Coherence
Authors: Miller Nathaniel R. , Ramelow Sven , Plick William N.
Published: May 2021

We theoretically analyze the phase sensitivity of the Induced-Coherence (Mandel-Type) Interferometer, including the case where the sensitivity is "boosted" into the bright input regime with coherent-light seeding. We find scaling which reaches below the shot noise limit, even when seeding the spatial mode which does not interact with the sample – or when seeding the undetected mode. It is a hybrid of a linear and a non-linear (Yurke-Type) interferometer, and aside from the supersensitivity, is distinguished from other systems by "preferring" an imbalance in the gains of the two non-linearities (with the second gain being optimal at low values), and non-monotonic behavior of the sensitivity as a function of the gain of the second non-linearity. Furthermore, the setup allows use of subtracted intensity measurements, instead of direct (additive) or homodyne measurements – a significant practical advantage. Bright, super-sensitive phase estimation of an object with different light fields for interaction and detection is possible, with various potential applications, especially in cases where the sample may be sensitive to light, or is most interesting in frequency domains outside what is easily detected, or when desiring bright-light phase estimation with sensitive/delicate detectors. We use an analysis in terms of general squeezing and discover that super-sensitivity occurs only in this case – that is, the effect is not present with the spontaneous-parametric-down-conversion approximation, which many previous analyses and experiments have focused on.
Time-dependent unbounded Hamiltonian simulation with vector norm scaling
Authors: An Dong , Fang Di , Lin Lin
Published: May 2021

The accuracy of quantum dynamics simulation is usually measured by the error of the unitary evolution operator in the operator norm, which in turn depends on certain norm of the Hamiltonian. For unbounded operators, after suitable discretization, the norm of the Hamiltonian can be very large, which significantly increases the simulation cost. However, the operator norm measures the worst-case error of the quantum simulation, while practical simulation concerns the error with respect to a given initial vector at hand. We demonstrate that under suitable assumptions of the Hamiltonian and the initial vector, if the error is measured in terms of the vector norm, the computational cost may not increase at all as the norm of the Hamiltonian increases using Trotter type methods. In this sense, our result outperforms all previous error bounds in the quantum simulation literature. Our result extends that of [Jahnke, Lubich, BIT Numer. Math. 2000] to the time-dependent setting. We also clarify the existence and the importance of commutator scalings of Trotter and generalized Trotter methods for time-dependent Hamiltonian simulations.
Parallel entangling gate operations and two-way quantum communication in spin chains
Authors: Yousefjani Rozhin , Bayat Abolfazl
Published: May 2021

The power of a quantum circuit is determined through the number of two-qubit entangling gates that can be performed within the coherence time of the system. In the absence of parallel quantum gate operations, this would make the quantum simulators limited to shallow circuits. Here, we propose a protocol to parallelize the implementation of two-qubit entangling gates between multiple users which are spatially separated, and use a commonly shared spin chain data-bus. Our protocol works through inducing effective interaction between each pair of qubits without disturbing the others, therefore, it increases the rate of gate operations without creating crosstalk. This is achieved by tuning the Hamiltonian parameters appropriately, described in the form of two different strategies. The tuning of the parameters makes different bilocalized eigenstates responsible for the realization of the entangling gates between different pairs of distant qubits. Remarkably, the performance of our protocol is robust against increasing the length of the data-bus and the number of users. Moreover, we show that this protocol can tolerate various types of disorders and is applicable in the context of superconductor-based systems. The proposed protocol can serve for realizing two-way quantum communication.

Published: May 2021

O presente artigo explora os processos envolvidos na retomada anafórica de uma representação conceitual (coletiva ou distributiva), resultado de uma operação de quantificação que envolve o mapeamento de dois conjuntos e as relações estabelecidas entre eles. Com base no mecanismo de retomada, é investigada a interpretação preferencial associada aos quantificadores universais todo(s) e cada no PB. O custo de retomada do pronome anafórico se mostrou diferenciado para cada um dos itens pesquisados. Os resultados experimentais vão de encontro aos estudos prévios e sugerem que, enquanto expressões quantificadas com todos e cada remetem a interpretações coletivas e distributivas, respectivamente, o quantificador todo apresenta um padrão menos definido.

DESCOMPASSOS IDENTITÁRIOS NO FALAR EM LÍNGUA ESTRANGEIRA: UM ESTUDO DAS MARCAS LINGUÍSTICAS DA INDETERMINAÇÃO DO DISCURSO EM LE
Authors: Vereza Solange Coelho , Lopes Vivian Mendes
Published: May 2021

O artigo problematiza a indeterminação no discurso em língua estrangeira (VEREZA, 2002) – a distância entre o querer e o poder dizer nessa prática de linguagem. O estudo procura identificar as marcas linguísticas dessa indeterminação em produções discursivas de licenciandos brasileiros em Letras Português-Inglês, a partir do exame do fenômeno da expressividade/avaliatividade nos textos (MARTIN e WHITE, 2005).

Finding Information Framework: A Tool to Teach Life-Long Learning Skills
Authors: Cohen-Osher Molly , Davies Theresa A. , Flynn David B. , Young Megan E. , Hoffman Miriam
Published: May 2021

Introduction: In this age of rapid information expansion, medical education can no longer be taught solely by information acquisition, but rather requires information management and information mastery at both the point of learning as well as at the clinical point of care. We must teach our trainees how to ask, categorize, and answer their own questions—skills required to be a life-long learner. We developed the Finding Information Framework (FIF), a conceptual algorithm as well as web-based tool and app, to guide medical students in asking and categorizing their questions and to link them directly to the most appropriate information resource for their questions. Here we assess the functionality of the FIF following its implementation in the first-year medical school curriculum problem-based learning (PBL) course.
Methods: First-year medical students (n=126) utilized the FIF in their longitudinal problem-based learning course discussion groups and completed an anonymous survey.
Results: Qualitative and quantative data suggest that the FIF was easy to use (86.5%), supported the course curriculum (80%), and helped students find relevant information to answer their questions (77%) from trusted reliable resources (70%). Qualitative comments also suggest that the FIF is initially a helpful tool during the PBL course but becomes less useful over time as students become more familiar with resources.
Conclusion: The FIF assists students in identifying trusted resources and in efficiently and effectively finding answers to questions at the point of learning. These data suggest that students are internalizing the tool’s conceptual algorithm over time, reinforcing the teaching of information management and information mastery.
Evolution of prudent predation in complex food webs: mechanism and evidence
Authors: Al-Khudhairy Orestes U. Gutierrez , Rossberg Axel G.
Published: May 2021

Prudent predators catch sufficient prey to sustain their populations
but not as much as to undermine their populations’ survival. The
idea that predators evolve to be prudent has been dismissed in the
1970s, but the blunt arguments invoked then are untenable in light
of modern evolution theory. Evolution of prudent predation has
repeatedly been demonstrated in two-species predator-prey
metacommunity models. However, the vigorous population fluctuations
that these models predict are not widely observed. Here we show
that in complex model food-webs prudent predation evolves by a
different mechanism. We make testable predictions for empirical
signatures of this mechanism and its outcomes. Then we discuss how
these predictions are borne out across freshwater, marine, and
terrestrial ecosystems. Demonstrating explanatory power of evolved
prudent predation well beyond the question of predator-prey
coexistence, the predicted signatures explain unexpected declines of
invasive alien species, the shape of stock-recruitment relations of
fish, and the clearance rates of pelagic consumers across the
latitudinal gradient and 15 orders of magnitude in body mass.
Specific research to further test and mobilise the utility of this
theory is proposed.
Monotone iterative technique for nonlinear differential equation of fractional order
Authors: Lu Zhengzhi , Yongjun Li , Shi Xiaoyan
Published: May 2021

In this paper, we mainly study the existence of solution of fractional
differential equations. Firstly, the existence of the maxmum solution
and minmum solution of the differential equation are proved by using the
fixed point theorem and the monotone iteration method. Secondly, the
existence of the solution of the original equation is proved by using
the newly constructed differential equation. Finally, the application of
the monotone iteration method is given through an example.
Lipoma across the Wall of the Right Atrium
Authors: FAN WEI , Liao Bin , Li Xin
Published: May 2021

A 44‑year‑old male patient was referred to our department with
unremarkable physical examination and laboratory data due to a mass
which was incidentally found in the right atrial during a routine
examination.Transthoracic and transesophageal echocardiography revealed
a 46×30 mm, well-delimited, non-mobile mass in the superior portion of
the right atrium. Besides the intracardiac mass, another low density was
detected in adjacent pericardial cavity at cardiac computed tomography
;he extracardiac mass appeared to be caused by invasive growth from the
intracardiac mass.An operation was performed through right anterolateral
minithoracotomy with the patient under hypothermic cardiopulmonary
bypass. During operation, it was found that the surface of the right
atrium was covered by an adipose mass (30×40 mm; Fig. 2A). Intracardiac
mass also showed yellow adipose tissue (40×50 mm; Fig. 2B). Both parts
of the mass infiltrated the myocardium. The mass was resected
completely; and right atrium was reconstructed by using bovine
pericardium pad. After the operation, the pathology confirmed the both
intracardiac and extracardiac tissues as lipoma; transthoracic
echocardiogram showed the atrial mass was removed completely and the
left ventricular ejection fraction was normal . The patient’s
postoperative course was uneventful and he was discharged home after 7
days.
Thin endometrial thickness is a risk factor for singleton low birth weight from single blastocyst transfer: A retrospective cohort study
Authors: Du Mingze , Zhang Junwei , Liu Manman , Wang Xingling
Published: May 2021

Objective To explore whether thin endometrial thickness (EMT) is
associated with singleton low birth weight (LBW) from single fresh
blastocyst transfer. Design Retrospective cohort study. Setting
Reproductive center. Population All women were ≤40 years old and
underwent single fresh blastocyst transfer and singleton live birth.
Interventions None. Methods Multivariable logistic regression was used
to evaluate the association between thin EMT and singleton LBW. Main
outcome measures LBW was the primary concern of this study. Results In
total, 2847 women met the study inclusion criteria. The neonatal
birthweight in the EMT ≤7.5 mm group was significantly lower than that
in the EMT 7.6~12.0 mm and EMT >12.0 mm
group (P<0.001). The rate of LBW in the EMT ≤7.5 mm group was
24.9%, which was significantly higher than the 4.0% in the EMT
7.6~12.0 mm group and the 5.3% in the EMT
>12.0 mm group (P<0.001). The total neonatal
malformation rate was similar between the groups (1.1%, 0.8% and
1.5%, P=0.21). After multiple logistic regression analysis, EMT≤7.5 mm
was an independent risk factor for LBW (adjusted odds ratio [AOR]:
4.39, 95% CI: 1.85～10.46, P<0.001). Conclusions Thin EMT
(≤7.5 mm) on the hCG trigger day is an independent risk factor for
singleton LBW from single fresh blastocyst transfer. The neonatal
birthweight in the EMT ≤7.5 mm group was significantly lower than that
in the EMT 7.6~12.0 mm and EMT >12.0 mm
groups. The total neonatal malformation rate was comparable between the
groups.
Particle-level dynamics of clusters: Experiments in a gas-fluidized bed
Authors: Wang Haifeng , Chen Yanpei , Wang Wei
Published: May 2021

The clustering is critical to understanding the multiscale behavior of
fluidization. However, its time-resolved evolution on the particle level
is seldom touched. Here, we explore both the time-averaged and
time-resolved dynamics of clusters in a quasi-2D fluidized bed. Particle
tracking velocimetry is adopted and then clusters are identified by
using the Voronoi analysis. The time-averaged results show that the
cluster hydrodynamic parameters depend highly on the cluster size and
the distance from the wall. The number distribution of the cluster size
follows a power law
(~n)) of
the percolation theory except for large clusters
(n>100). The time-resolved analysis
shows that the cluster coalescence can be simplified as a collision
between two inelastic clusters, during which the net external force is
roughly zero, and a snowplow model is proposed to predict its energy
loss, ΔE ~ t. The
cluster rupture is suggested to be caused by increasing torque.
Kinetics study of CWPO of phenol wastewater over Cu-ZSM-5/PSSF catalysts prepared by ion-exchanged method
Authors: Wu Yanjie , Zhang Huiping , Yan Ying
Published: May 2021

Cu-ZSM-5 was prepared on the paper-like sintered stainless steel fibers
(PSSF) by ion-exchange method for catalytic wet peroxide oxidation
(CWPO) of phenol in a fixed bed reactor. The prepared Cu-ZSM-5/PSSF
catalyst was characterized by SEM, BET, XRD, FT-IR and UV-vis,
respectively. And the effects of different catalyst bed height, reaction
temperature and feed flow rate on catalytic performance were
investigated to obtain optimum reaction condition. Finally, the
catalytic reaction kinetics analysis over Cu-ZSM-5/PSSF catalyst were
carried out with the Power-rate Law Kinetic model. The experimental
results showed that the reaction order was the first-order reaction, and
the activation energy of the oxidation reaction was Ea=72.9 kJ/mol. The
initial oxidation rate equation (−rA0=5.36×108 e−72994/RT CA) was
obtained for phenol degradation using Cu-ZSM-5/PSSF catalyst.
The Effects of Covid-19 on the Financial Sector and the Role of Social Media as an Advertising Tool in these Trying Times in Zimbabwe
Authors: Chirume Enesiti
Published: May 2021

This study identifies the effects of COVID-19 on the financial sector and explores the part played by social media as an advertising instrument in Zimbabwe. The objectives of the study are - (i) to identify the effects of COVID-19 on the financial sector in Zimbabwe. ii) To appraise the function of social media as an advertising vehicle in these trying times, in Zimbabwe. Drawing respondents from ten (10) leading financial institutions in Zimbabwe, the study uses a self-administered interview schedule and adopts the qualitative research design. Challenges identified range from managing the legal tender and interchangeability to methodizing working routine (dropping profits and staff well-being). There are also pressures on financial institutions notably, the rise of fintech within the sector to serve customer needs. Even though the pandemic has a terrible negative impact, thanks to social media for becoming primary sources of information. This paper agrees with some scholarly views on what ought to be the additional and new role of social media as an advertising tool- and that is relating social media benefactions to the concurrent milieu. For financial institutions, it is not business as usual. The substance of the matter is that duration of the plight and its impact are still undetermined in Zimbabwe and elsewhere. This phase presents a singular chance for the financial institutions in Zimbabwe to use social media advertising to its best, to tether with clients in significant ways. This includes adjusting advertising campaigns, evaluating the language used in advertisements and becoming aware of consumers' increased anxiety during these trying times. The study recommends that financial institutions have to think through creative advertising strategies and practices that may navigate the business through this “new normal.” They should use social media more for communal rather than for commercial purposes now and after.
Meta-Analysis of Seven Standard Experimental Paradigms Comparing Student to Non-student
Authors: Zumaeta Jorge N.
Published: May 2021

This study embarked on the very challenging proposition of systematically organizing and classifying an assortment of experimental economics essays pertinent to seven experiments performed with both non-student and student populations. The experiments were the Dictator game, Stag Hunt – Coordination game, Risk Aversion Measurement (as measured by the players type of lottery choice), Trust game, Guessing game, Prudence Measurement, and the Guessing game. This meta-analysis reviewed 126 published and unpublished papers collected from several journals and papers provided by several authors via the Google Groups "Economic Science Association - Experimental Methods Discussion" group. Ultimately, only 39 studies were utilized due to methodological alignment. While some studies showed statistically significant differences between non-students and students as indicated by their respective 95% confidence intervals, the overall random-effects model of each of the seven games showed not to be statistically significant. This study contributes to the literature in three important ways. First, the study generates a comprehensive inventory and review of experiments comparing student to non-student populations for the last four decades;  second, the study points out a possible limitation when combining several studies of the same game, despite following similar protocols, suggesting that compounded contextual complexities might diminish aggregate effects of the individuals’ behavioral responses to the financial incentives, and third, the study indicates that generalizations from one experimental economic study, may not render a solid base for extending statistical extrapolations applicable to the total population since the aggregate effects do not indicate substantial differences.
