Modelling the Adsorption of Arsenic from Water and Wastewater using Microsoft Excel Solver and SPSS
Authors: Oke I. A
Published: August 2022

Arsenic (As) poisoning is toxic to human organs and tissues (the heart, bones, intestines, kidneys, and reproductive and nervous systems). This paper focused on the modelling fittings of removal of As from water and typical industrial wastewaters through adsorption. Equilibrium isotherm parameters were determined using Microsoft Excel Solver (MES) and SPSS methods. The study revealed that equilibrium isotherms for As adsorption from aqueous solutions can be grouped into two based on the values of correlation coefficient (R2) as follows: adsorption equilibrium isotherms with R2 greater than 0.95 and R2 less than 0.95. Microsoft Excel Solver method was found to be as accurate as SPSS method based MSC, CD, R and AIC. The study concluded that MES can be used for model fitting based on accuracy and cost (at no additional cost of purchase and installation unlike SPSS).

Published: August 2022

In contrast to secondary pneumomediastinum who has an identifiable cause, spontaneous pneumomediastinum is a rare clinical entity defined as the presence of free air in the mediastinal structures not associated with trauma. Its main causes are vomiting, exercise, drugs, asthma, difficult labour and Valsalva maneuvers. Its classic clinical presentation is retrosternal chest pain, dyspnoea and subcutaneous emphysema. Chest X-ray or ideally a chest CT scan confirms the diagnosis. Before retaining the spontaneous character of the pneumomediastinum, several investigations should be carried out in order to detect an obvious cause such as iatrogenic or traumatic perforation of the oesophagus, trachea, or respiratory tract and intrathoracic infection. The prognosis is usually excellent without specific treatment and the recurrences are poorly described in the literature. We report the case of a 30-year-old female patient presenting dyspnoea, chest pain and facial swelling with a history of chronic vomiting over the past year and two previous episodes of similar symptomatology and who was diagnosed with recurrent spontaneous pneumomediastinum.
Fibrodysplasia Ossificans Progressiva in Children: A Case Report
Authors: Moussaid Zainab , Zaidane Israa , Mekkaoui Nour , Dakhama Badr Sououd Benjelloun , Karboubi Lamya
Published: August 2022

Fibrodysplasia ossificans progressiva (FOP) is a rare autosomal dominant genetic disease. The diagnosis is clinical and is based on two criteria: congenital bone deformities of the hands and feet (in particular a bilateral hallux valgus with a monophalangeal appearance) and ossification of the interstitial connective tissue of the striated muscles (spontaneous or triggered by minimal trauma). This irreversible ectopic osteogenesis evolves in bouts, progressing according to a precise anatomical pattern. The hypothesis of a genetic mutation in the BMP4 signaling pathway, responsible for a dysfunction of the immune system, has been evoked for some years. Recently, a gene involved was identified on chromosome 2: it is ACVR1, one of the BMP receptors. FOP is an example of the difficulty of management, since no curative treatment is effective on the progression of the disease; only preventive and conservative management associated with symptomatic treatment of relapses can be proposed at present.

Introduction and aims: Post-myocardial infarction ventricular septal defect is a rare dreadful complication of myocardial infarction. It usually occurs between the 3rd and 7th day of the infarction. Several risk factors for its occurrence have been identified. The aim of our work is to discuss these different risk factors through clinical cases with a literature review. Material and methods: This is a retrospective study conducted from 2015 to 2021 including 18 consecutive patients with post-myocardial ventricular septal defect presented in either cardiac intensive care unit or cardiac surgery department of Mohammed V Military Teaching Hospital Rabat. All patients had at least a clinical examination, an electrocardiogram, and an echocardiogram showing ventricular septal defect. Surgery was performed at cardiac surgery department. Results: Mean age was 65.2± 26.4 years. There were more men than women in our study (17 males/1 female). Diabetes (55.6%) and smoking (55.6%) were the two predominant cardiovascular risk factors. The average body mass index was 23.7 ± 2.98 kg/m². Anteroseptal was the most observed infarct location (38.9%.) 16 patients presented after 12 hours of pain onset. 2 of them underwent percutaneous intervention and 1 underwent coronary artery bypass graft intervention whereas 15 didn't undergo any revascularisation strategy. The culprit artery was left anterior descending artery in 13 patients. The death rate was 55.6%, 50% before surgery and 50% after surgery. Conclusion: Delayed or absence of coronary reperfusion remains the main risk factor for post-myocardial infarction ventricular septal defect occurrence which explains its frequency decline since reperfusion strategies development.

Published: August 2022

Background: The Covid-19 pandemic has globally impacted how people interact, communicate and work. Facemask use has been advocated by the World health organization (WHO) and several global bodies with growing studies linking its accurate use to decreasing COVID-19 variant cases and associated deaths. For it to be effective in preventing further transmission of Covid-19 and its variants, they have to be worn properly and correctly. Health experts globally and the Nigerian Center for Disease Control (NCDC) have also issued guidelines on the use of facemask within the hospital environment in combination with regular hand hygiene and physical and social distancing to curtail the spread of the virus. Unfortunately information is scanty on the extent to which commuters visiting hospitals comply with this regulatory preventive behaviour. This study therefore assessed the level of compliance with the use of face masks and influencing factors among University College Hospital (UCH) Ibadan commuters. Methods: A descriptive cross-sectional study design and observatory survey was used. The sample population was calculated using the Cochran formula and a standard normal value of 1.96 at 95% confidence interval and 5% marginal error with a prevalence of 50%. A simple random sampling technique was adopted in selecting the target population of 260 commuters within UCH premises. Data collection was carried out within 3days from the hours of 8 am -10 am and 12 pm–2 pm. The information obtained from respondents includes the socio-demographic characteristics, knowledge of Covid-19, adherence to the use of facemask, factors promoting and hindering use among users and non-users, satisfaction towards the use of facemask, and the willingness to use facemask in the future. Data was coded and entered into the IBM statistical package for social sciences (SPSS 22nd edition) to analyze and interpret the data collected. Tables, inferences and charts were used for data representation. ...........
Crash Modification Factors for Contrast Pavement Markings on Light-Colored Pavement
Authors:   Indiana State University, Williamson Michael , Singh Sumit ,   Indiana State University
Published: August 2022

Roadway departure crashes are a leading cause of fatal and severe injury crashes on high-speed roadways. The objective of this project was to evaluate the safety benefits of contrast pavement markings and to develop a benefit-cost analysis tool for use in project selection. A nationwide survey was developed and deployed to departments of transportation and highway agencies that identified the use of contrast pavement markings at the national level. The survey further determined that no safety benefits have been quantified by any other agency. A before-and-after study using an empirical Bayes approach was conducted on 70 miles of urban/suburban roadways and included data from six states. Crash modification factors were developed for three roadway types at three crash severity levels, all showing a decrease in crashes with the use of contrast pavement markings. The results of this research can be used to predict the type of crash reductions that can be expected when installing contrast pavement markings on high-speed roadways. A benefit-cost analysis tool was also developed and can be used to evaluate the expected reduction in roadway departure crashes on a given roadway section at each crash severity level. The benefit-cost tool provides justification for the extra cost of contrast pavement markings.
A CENTRALIDADE METROPOLITANA EM PEDAÇOS: REFLEXÕES SOBRE OS NOVOS CENTROS E SUAS CENTRALIDADES
Authors: Da Silva Oséias Teixeira
Published: August 2022

O presente texto busca ser uma contribuição para a pesquisa da centralidade metropolitana. O caminho de análise escolhido para isso foi o seguinte: em primeiro lugar realizamos algumas distinções teóricas importantes relacionadas a essa temática; em segundo lugar, com base nessa discussão, tratamos de um fenômeno recente dentro dessa temática que é o surgimento das chamadas “novas centralidades”. A primeira distinção tratada no texto é entre a centralidade da metrópole e a centralidade na metrópole. A centralidade da metrópole ocorre em escala regional, e a centralidade na metrópole na escala intra-urbana. A segunda distinção é entre o centro, realidade material originada a partir do processo de centralização, e a centralidade, capacidade de polarização de um centro a partir de sua configuração material. Com base nessas distinções buscamos em seguida tratar das características dos “novos centros” e da centralidade que os mesmos expressam confrontando essas características com os dos centros tradicionais.

A non-linear encryption approach for compressed grayscale and color images is proposed in Double Random Phase Encoding (DRPE) setup using two compression algorithms: Set Partitioning in Hierarchical Trees (SPIHT) and Run-length encoding (RLE). The compressed image is then segmented and embedded in multiple Quick Response (QR) codes, which are combined again into a single image. Further, this single image is scrambled by two-coupled chaos logistic maps, at which the scrambled image is now ready for DRPE encryption. The use of two-coupled chaos logistic increases the security level of this proposed DRPE encryption from various attacks. The proposed DRPE encryption is extended to handed color images, which are segregated into three color-channels (Red, Green and Blue), where each channel is individually encrypted. For grayscale images, the proposed system will have three security key codes while for color images it has nine security key codes. The robustness and invulnerability of the proposed scheme against various attacks is demonstrated through cryptoanalysis and computer simulation results.

Authors: Reinfeld Howard B
Published: August 2022

Amphetamines and cocaine belong to a family of medications known as stimulants, which increase the speed of neurotransmission in which the brain relays instructions to the rest of the body. Stimulants directly affect the central nervous system and boost metabolic rate, respiratory rate, blood pressure, and attention.

More briefly, stimulants are psychoactive agents that produce short-term enhancements in physical or mental performance and are commonly referred to as "uppers." To name a few, cocaine, ecstasy, and dexamphetamine are widely used stimulants while Ice (crystal methamphetamine) is the most powerful abusive stimulant substance.

Short-term perceptual reweighting in suprasegmental categorization
Authors: Jasmin Kyle , Tierney Adam , Obasih Chisom , Holt Lori
Published: August 2022

Segmental speech units such as phonemes are described as multidimensional categories whose perception involves contributions from multiple acoustic input dimensions, and the relative perceptual weights of these dimensions respond dynamically to context. For example, when speech is altered to create an “accent” in which two acoustic dimensions are correlated in a manner opposite that of long-term experience, the dimension that carries less perceptual weight is down-weighted to contribute less in category decisions. It remains unclear, however, whether this short-term reweighting extends to perception of suprasegmental features that span multiple phonemes, syllables, or words, in part because it has remained debatable whether suprasegmental features are perceived categorically. Here, we investigated the relative contribution of two acoustic dimensions to word emphasis. Participants categorized instances of a two-word phrase pronounced with typical covariation of fundamental frequency (F0) and duration, and in the context of an artificial “accent” in which F0 and duration (established in prior research on English speech as “primary” and “secondary” dimensions, respectively) covaried atypically. When categorizing “accented” speech, listeners rapidly down-weighted the secondary dimension (duration). This result indicates that listeners continually track short-term regularities across speech input and dynamically adjust the weight of acoustic evidence for suprasegmental decisions. Thus, dimension-based statistical learning appears to be a widespread phenomenon in speech perception extending to both segmental and suprasegmental categorization.
Test-retest reliability of a smartphone-based approach-avoidance task: Effects of retest period, stimulus type, and demographics
Authors: Zech Hilmar G. , Gable Philip , van Dijk Wilco W. , van Dillen Lotte F.
Published: August 2022

The approach-avoidance task (AAT) is an implicit task that measures people’s behavioral tendencies to approach or avoid stimuli in the environment. In recent years, it has been used successfully to help explain a variety of health problems (e.g., addictions and phobias). Unfortunately, more recent AAT studies have failed to replicate earlier promising findings. One explanation for these replication failures could be that the AAT does not reliably measure approach-avoidance tendencies. Here, we first review existing literature on the reliability of various versions of the AAT. Next, we examine the AAT’s reliability in a large and diverse sample (N = 1077; 248 of whom completed all sessions). Using a smartphone-based, mobile AAT, we measured participants’ approach-avoidance tendencies eight times over a period of seven months (one measurement per month) in two distinct stimulus sets (happy/sad expressions and disgusting/neutral stimuli). The mobile AAT’s split-half reliability was adequate for face stimuli (r = .85), but low for disgust stimuli (r = .72). Its test–retest reliability based on a single measurement was poor for either stimulus set (all ICC1s < .3). Its test–retest reliability based on the average of all eight measurements was moderately good for face stimuli (ICCk = .73), but low for disgust stimuli (ICCk = .5). Results suggest that single-measurement AATs could be influenced by unexplained temporal fluctuations of approach-avoidance tendencies. These fluctuations could be examined in future studies. Until then, this work suggests that future research using the AAT should rely on multiple rather than single measurements.

Published: August 2022

In this study, we present the first database of pictures and their corresponding psycholinguistic norms for Polish: the CLT database. In this norming study, we used the pictures from Cross-Linguistic Lexical Tasks (CLT): a set of colored drawings of 168 object and 146 actions. The CLT pictures were carefully created to provide a valid tool for multicultural comparisons. The pictures are accompanied by norms for Naming latencies, Name agreement, Goodness of depiction, Image agreement, Concept familiarity, Age of acquisition, Imageability, Lexical frequency, and Word complexity. We also report analyses of predictors of Naming latencies for pictures of objects and actions. Our results show that Name agreement, Concept familiarity, and Lexical frequency are significant predictors of Naming latencies for pictures of both objects and actions. Additionally, Age of acquisition significantly predicts Naming latencies of pictures of objects. The CLT database is freely available at osf.io/gp9qd. The full set of CLT pictures, including additional variants of pictures, is available on request at osf.io/y2cwr.

Authors: Douglas Jennifer , Alisauskas Alexandra , Bassett Elizabeth , Duranseaud Noah , Lee Ted , Mantey Christina
Published: August 2022

This article reports on findings of a series of interviews conducted with 27 archivists on the topic of grief and other emotions in archival work. Centering the words of the interviewed archivists and demonstrating a research ethic of deep listening, this article describes how the interviewed archivists encounter and experience grief and other emotions as part of working with records, researchers, and donors. Interview participants highlighted a lack of preparation for the emotional dimensions of archival work as well as difficulty and damaging silences surrounding emotions in the archival work. This article argues that a first step toward transformative change in the way archival education programs and workplaces address the emotional dimensions of archival work requires sincere and committed acknowledgment of these dimensions and of archival work as person-centered and relational.

Utilization of telehealth to manage the Covid-19 pandemic in low and middle income countries: a scoping review protocol
Authors:   Health Management Research Institute, Iran University of Medical Sciences, Tehran, Iran., Jahromi Maryam Eslami , Ayatollahi Haleh
Published: August 2022

Review question / Objective: How was telehealth utilized to manage the Covid-19 pandemic in low and middle income countries? Rationale: Low- and middle-income countries (LMICs) often experienced significant challenges in providing telehealth interventions due to limited resources and technology. A review of the literature shows that a small number of LMICs changed their management strategies during the Covid-19 pandemic and moved towards using telehealth. There is a lack of evidence about the practical implementation of telehealth in LMICs. As a result, the present study aimed to review the utilization of telehealth to manage the Covid-19 pandemic in low- and middle-income countries focusing on implementations. In this study, how to implement telehealth in LMICs in response to the COVID-19 pandemic, including telehealth platforms used, the impact, pros and barriers encountered in implementation and adoption of telehealth interventions, are reviewed. The implementation of telehealth systems in different LMICs may pose both similar and different challenges. The lessons learned from this study can be useful for improving implementation of digital health interventions including LMICs in different countries.

Published: August 2022

Microfluidic paper-based analytical devices (μPADs) are highly in demand because of their important usage in the field of medical diagnostic, biology and environmental testing. Porous media has been used as a μPADs with the benefits of cost-effective, excellent performance and ease of usage. Recently, porous media from paper-based filter paper has also been used as the main component for a self-powered imbibing micropump actuation. In this study, characterization of porous media from different specifications of Whatman ashless grade W40, W41 and W42 filter papers has been studied. In addition, the wicking or capillary flow capability of the porous media under an open and confined environment was also analyzed. Scanning Electron Microscope (SEM) and ImageJ image processing have been used as the method to determine the filter paper characteristics. Whatman filter paper grade W41 has the highest percentage of porosity which is 70.82 %. The porosity of filter paper grade W40 and W42 are 70.24 % and 61.8 % respectively. Meanwhile, experiments were conducted to understand the water wicking process for Whatman filter paper for different paper shapes and environments. Diamond-shaped filter paper resulted in faster wicking in the free environment compared with the constraint environment. The percentage difference of the wicking under these environments is 61.56 % and 141.09 % for W40 and W41 filter paper respectively. The experiment conducted also confirmed that the wicking behavior of the capillary height of the liquid in filter paper is proportional to the square root of the time. This result agreed well with the Lucas-Washburn equation. In conclusion, the characteristics of the liquid flow in porous media are closely related to its specification as provided by the manufacturer. Furthermore, the decrease of liquid wicking in a confined environment is the result of the high resistance of a liquid to flow with decreased filter paper porosity, permeability and thickness. This study provides important findings that will help in the optimization and best design of self-powered imbibing micropump for microfluidic device development.

The computational method has long been used in propeller turbine studies. However, there has not yet been a comprehensive explanation for mesh and timestep independency method or verification for propeller turbine simulation. Hence, this study explains propeller turbines' mesh and timestep independency method. The computational software for this case is ANSYS® FLUENT 18.2™. The grid convergency index (GCI) and the Courant number (Cn) analysis determine the optimum mesh and timestep size. Based on the results, the mesh number of 691996 (medium) is considered appropriate in this case because the GCI is below 1%. The 691996 mesh has a size (Δx) of 0.432 mm. The Cn is 0.72 (the water velocity of 0.63 m/s) based on the investigation; therefore, the timestep size for this case of 0.0005s. Then, verification of the CFD results in the propeller turbine can be indicated by visualising the pressure contour; the pressure on the upper side of the runner should be higher than the lower side. The deviation average of CFD results in secondary data of 14.48%. The deviation is presumably because of missed information about the CFD setup geometry with real conditions. Thus, the independency method using the GCI method and Cn analysis is recommended for propeller turbines. CFD results show that torque, power generated, and efficiency of the propeller turbine toward its rotation have a similar pattern to secondary data; it can indicate that the CFD results of the propeller turbine are verified.
Long-term Evolution of Supercritical Black Hole Accretion with Outflows: A Subgrid Feedback Model for Cosmological Simulations

We study the long-term evolution of the global structure of axisymmetric accretion flows onto a black hole (BH) at rates substantially higher than the Eddington value (

), performing 2D hydrodynamical simulations with and without radiative diffusion. In the high-accretion optically thick limit, where the radiation energy is efficiently trapped within the inflow, the accretion flow becomes adiabatic and comprises turbulent gas in the equatorial region and strong bipolar outflows. As a result, the mass inflow rate decreases toward the center as

. The global structure of the flow settles down to a quasi-steady state in millions of the orbital timescale at the BH event horizon, which is ≳10–100 times longer than that addressed in previous (magneto-)RHD simulation studies. Energy transport via radiative diffusion accelerates the outflow near the poles in the inner region but does not change the overall properties of the accretion flow compared to the cases without diffusion. Based on our simulation results, we provide a mechanical feedback model for super-Eddington accreting BHs. This can be applied as a subgrid model in large-scale cosmological simulations that do not sufficiently resolve galactic nuclei, and to the formation of the heaviest gravitational-wave sources via accretion in dense environments.
Debye-scale Solitary Structures in the Martian Magnetosheath

We present an analysis of 450 solitary wave pulses observed by the Langmuir Probe and Waves instrument on the Mars Atmosphere and Volatile EvolutioN spacecraft during its five passes around Mars on 2015 February 9. The magnitude and duration of these pulses vary between 1 and 25 mV m−1 and 0.2–1.7 ms, respectively. The ambient plasma conditions suggest that these pulses are quasi-parallel to the ambient magnetic field and can be considered electrostatic. These pulses are dominantly seen in the dawn (5–6 LT) and afternoon-dusk (15–18 LT) sectors at an altitude of 1000–3500 km. The frequencies of these electric field pulses are close to the ion plasma frequency (i.e., f
pi ≤ f
ef ≪ f
pe), which suggests that their formation is governed by ion dynamics. The computer simulation performed for the Martian magnetosheath plasma hints that these pulses are ion-acoustic solitary waves generated by drifted ion and electron populations and their spatial scales are in the range of few ion Debye lengths (1.65–10λ
di). This is the first study to report and model solitary wave structures in the Martian magnetosheath.
Constraining the Ellipticity of the Newborn Magnetar with the Observational Data of Long Gamma-Ray Bursts

Published: August 2022

The X-ray plateau emission observed in many long gamma-ray bursts (LGRBs) has been usually interpreted as the spin-down luminosity of a rapidly spinning, highly magnetized neutron star (millisecond magnetar). If this is true, then the magnetar may emit extended gravitational wave (GW) emission associated with the X-ray plateau due to nonaxisymmetric deformation or various stellar oscillations. The advanced LIGO and Virgo detectors have searched for long-duration GW transients for several years; no evidence of GWs from any magnetar has been found until now. In this work, we attempt to search for signatures of GW radiation in the electromagnetic observation of 30 LGRBs under the assumption of the magnetar model. We utilize the observations of the LGRB plateau to constrain the properties of the newborn magnetar, including the initial spin period P
0, dipole magnetic field strength B

. In addition, we derive the GW strain for the magnetar sample via their spin-down processes, and find that the GWs from these objects may not be detectable by the aLIGO and Einstein Telescope (ET) detectors. For a rapidly spinning magnetar (P ∼ 1 ms, B ∼ 1015 G), the detection horizon for the advanced LIGO O5 detector is ∼180 Mpc. The detection of such a GW signal associated with the X-ray plateau would be a smoking gun that the central engine of a GRB is a magnetar.

The neutral atomic gas content of individual galaxies at large cosmological distances has until recently been difficult to measure due to the weakness of the hyperfine H i 21 cm transition. Here we estimate the H i gas mass of a sample of main-sequence star-forming galaxies at z ∼ 6.5–7.8 surveyed for [C ii] 158 μm emission as part of the Reionization Era Bright Emission Line Survey (REBELS), using a recent calibration of the [C ii]-to-H i conversion factor. We find that the H i gas mass excess in galaxies increases as a function of redshift, with an average of M

to be consistent with recent simulations and argue that this apparent discrepancy is likely a consequence of the DLA sight lines predominantly probing the substantial fraction of H i gas in high-z galactic halos, whereas [C ii] traces the H i in the ISM associated with star formation. We make predictions for this buildup of neutral gas in galaxies as a function of redshift, showing that at z ≳ 5, only ≈10% of the cosmic H i gas content is confined in galaxies and associated with the star-forming ISM.
Water Shielding in the Terrestrial Planet-forming Zone: Implication for Inner Disk Organics
Authors: Duval Sara E. , Bosman Arthur D. , Bergin Edwin A.
Published: August 2022

The chemical composition of the inner region of protoplanetary disks can trace the composition of planetary-building material. The exact elemental composition of the inner disk has not yet been measured and tensions between models and observations still exist. Recent advancements have shown UV shielding to be able to increase the emission of organics. Here, we expand on these models and investigate how UV shielding may impact chemical composition in the inner 5 au. In this work, we use the model from Bosman et al. and expand it with a larger chemical network. We focus on the chemical abundances in the upper disk atmosphere where the effects of water UV shielding are most prominent and molecular lines originate. We find rich carbon and nitrogen chemistry with enhanced abundances of C2H2, CH4, HCN, CH3CN, and NH3 by >3 orders of magnitude. This is caused by the self-shielding of H2O, which locks oxygen in water. This subsequently results in a suppression of oxygen-containing species like CO and CO2. The increase in C2H2 seen in the model with the inclusion of water UV shielding allows us to explain the observed C2H2 abundance without resorting to elevated C/O ratios as water UV shielding induced an effectively oxygen-poor environment in oxygen-rich gas. Thus, water UV shielding is important for reproducing the observed abundances of hydrocarbons and nitriles. From our model result, species like CH4, NH3, and NO are expected to be observable with the James Webb Space Telescope (JWST).
