Authors: Rodríguez Díaz Yim James , Fuentes Guevara Miguel David , Beleño Díaz Óscar David , Montoya Armenta Luis Hernando 
Published: July 2021

Contexto: La electrocoagulación (EC) se ha convertido en un proceso viable que permite reutilizar las aguas residuales industriales, mediante un reactor eléctrico. Esta técnica aplica los fundamentos de la coagulación y floculación permitiendo la reutilización de estas aguas.
Objetivo: Este estudio pretende evaluar la eficiencia de la técnica de EC para el tratamiento de aguas residuales mixtas provenientes de la industria de lácteos y cárnicos (ARLC).
Metodología: El agua residual utilizada para esta investigación fue obtenida del efluente de la planta de productos lácteos y cárnicos de la Universidad Popular del Cesar (UPC). Se investigó el efecto de dos variables de diseño de un electrocoagulador tipo Bach rectangular, sobre las características fisicoquímicas de las ARLC durante el proceso de EC: número de electrodos y tiempo de tratamiento. Las características del agua residual utilizadas como indicadores de la eficiencia de tratamiento del electrocoagulador fueron DQOtotal, DQOsoluble, conductividad eléctrica, pH y turbiedad. La variable de diseño del electrocoagulador referente a número de electrodos consistió en tres montajes de 3, 6 y 13 electrodos de hierro conectados en paralelo, energizados con una fuente de corriente directa (DC) de 360 W, a un voltaje constante de 12 V. La variable de tiempo de tratamiento fue máxima de 60 minutos con evaluación de los indicadores de las aguas residuales cada 15 minutos.
Resultados: Durante los experimentos de EC, la configuración de 13 electrodos en paralelo fue la mejor para el tratamiento de las ARLC, lo que permitió la remoción de DQOtotal, DQOsoluble, y turbiedad, con eficiencia máxima de reducción de 96 %, 95 % y 94 %, respectivamente. Contrariamente, la EC aumentó los valores de conductividad eléctrica, corriente y pH, de los cuales se obtuvieron valores medios finales de 2785 µS cm-1, 11,6 A y 12,63, respectivamente.
Conclusiones: El sistema de electrocoagulación tipo Bach rectangular demostró ser eficiente durante su operación con 13 electrodos y 60 minutos de retención durante el tratamiento de las ARLC.

Published: July 2021

In this study, the wastes from cassava (CAW) and peach palm (PPW) agro-industries were investigated as potential low-cost biosorbents for removing the tartrazine yellow dye (TAR). The by-products were prepared by washing and drying steps and characterized into physicochemical parameters and microstructure. The effects of contact time, pH, dosage and dye concentration were analyzed for the biosorbents in comparison to commercial activated carbon (AC). The biosorbents were applied to the treatment of an effluent from a juice industry containing TAR. Cellulose was the main component of the biosorbents (31.47–51.20 g 100 g-1), which was correlated to the functional groups identified by ATR-FTIR spectra and the materials had a porous surface. The zero point of charge was 3.75 for PPW and 4.60 for CAW. The pH parameter had a significant effect on the adsorption process, with the maximum values of adsorption being reached at pH 2.0, with removal of 94.7% for PPW, 74.4% for CAW and 97.7% for AC, at the dosage of 7.5 g L-1 at 25.0 ºC. The adsorption of TAR was fast in the early stages, and at 120 min the three adsorbents reached the equilibrium. Isotherms of adsorption showed that Langmuir’s and Freundlich’s models fitted the best to the CAW and PPW experimental data, respectively. The wastes evaluated in this work can be an interesting alternative to TAR adsorption in the industrial effluent without being subjected to chemical treatments.

Modeling the dynamics of viral–host interaction during treatment of productively infected cells and free virus involving total immune response
Authors: Dubey Preeti , Dubey Uma S. , Dubey Balram 
Published: July 2021

Virus dynamics models are useful in interpreting and predicting the change in viral load over the time and the effect of treatment in emerging viral infections like HIV/AIDS, hepatitis B virus (HBV).We propose a mathematical model involving the role of total immune response (innate, CTL, and humoral) and treatment for productively infected cells and free virus to understand the dynamics of virus–host interactions. A threshold condition for the extinction or persistence of infection, i.e. basic reproductive number, in the presence of immune response (RI ) is established. We study the global stability of virus-free equilibrium and interior equilibrium using LaSalle’s principle and Lyapunov’s direct method. The global stability of virus-free equilibrium ensures the clearance of virus from the body, which is independent of initial status of subpopulations. Central manifold theory is used to study the behavior of equilibrium points at RI = 1, i.e. when the basic reproductive number in the presence of immune response is one. A special case, when the immune response (IR) is not present, has also been discussed. Analysis of special case suggests that the basic reproductive number in the absence of immune response R0 is greater than that of in the presence of immune response RI , i.e. R0> RI . It indicates that infection may be eradicated if RI < 1. Numerical simulations are performed to illustrate the analytical results using MatLab and Mathematica.

Published: July 2021

OBJECTIVES
To assess an educational intervention (BeSMART) for parents of hospitalized children on behaviors, beliefs, and knowledge about firearm safety.

METHODS
A randomized controlled, 3-arm preintervention and postintervention study compared BeSMART video and handout interventions (with and without physician review) to tobacco smoke videos and handouts (control) on parental behaviors, beliefs, and knowledge. Eligibility criteria included parents and/or guardians residing with hospitalized children aged &lt;20 years. The primary outcome was a change in parent-reported frequency of asking about guns in homes visited by their children preintervention to 1 month after intervention. Secondary outcomes were parent-reported likelihood of asking about guns in others’ homes immediately postintervention and change in firearm safety beliefs and/or knowledge in the intervention versus control group, analyzed with analysis of variance. McNemar’s and paired t tests compared changes within groups, and generalized estimating equations compared change between groups for the primary outcome.

RESULTS
A total of 225 participants enrolled. Both intervention and control groups revealed significant increase mean in parent-reported Likert score of frequency of asking about guns within groups preintervention to 1 month after intervention (BeSMART: 1.5 to 2.3, P = .04; BeSMART + physician review: 1.4 to 1.9, P = .03; control: 1.4 to 2.3, P = .01). Change between groups was not significant (P = .81). Immediately postintervention, intervention groups reported higher likelihood of asking about guns (P &lt; .001). Study groups revealed no significant differences in beliefs. Firearm safety knowledge increased significantly in the intervention groups.

CONCLUSIONS
BeSMART firearm injury prevention intervention in a hospital setting increased parental knowledge regarding firearm safety. Immediately postintervention, BeSMART groups reported higher likelihood of asking about guns in others’ homes compared with controls. At 1 month after intervention, all groups reported increased frequency asking about guns. Future investigations are needed to understand the duration of intervention impact.

OBJECTIVES
To evaluate International Classification of Diseases, 10th Revision (ICD-10) coding strategies for the identification of patients with a brief resolved unexplained event (BRUE).

METHODS
Multicenter retrospective cohort study, including patients aged &lt;1 year with an emergency department (ED) visit between October 1, 2015, and September 30, 2018, and an ICD-10 code for the following: (1) BRUE; (2) characteristics of BRUE; (3) serious underlying diagnoses presenting as a BRUE; and (4) nonserious diagnoses presenting as a BRUE. Sixteen algorithms were developed by using various combinations of these 4 groups of ICD-10 codes. Manual chart review was used to assess the performance of these ICD-10 algorithms for the identification of (1) patients presenting to an ED who met the American Academy of Pediatrics clinical definition for a BRUE and (2) the subset of these patients discharged from the ED or hospital without an explanation for the BRUE.

RESULTS
Of 4512 records reviewed, 1646 (36.5%) of these patients met the American Academy of Pediatrics criteria for BRUE on ED presentation, 1016 (61.7%) were hospitalized, and 959 (58.3%) had no explanation on discharge. Among ED discharges, the BRUE ICD-10 code alone was optimal for case ascertainment (sensitivity: 89.8% to 92.8%; positive predictive value: 51.7% to 72.0%). For hospitalized patients, ICD-10 codes related to the clinical characteristics of BRUE are preferred (specificity 93.2%, positive predictive value 32.7% to 46.3%).

CONCLUSIONS
The BRUE ICD-10 code and/or the diagnostic codes for the characteristics of BRUE are recommended, but the choice between approaches depends on the investigative purpose and the specific BRUE population and setting of interest.

Published: July 2021

BACKGROUND AND OBJECTIVES
Because of severe and protracted shortages of pediatric behavioral health (BH) specialists, collaboration between pediatric primary care practitioners (PCPs) and BH specialists has the potential to increase access to BH services by expanding the BH workforce. In a previous study, we demonstrated that phase 1 of a behavioral health integration program (BHIP) enrolling 13 independently owned, community-based pediatric practices was associated with increased access to BH services while averting substantial cost increases and achieving high provider self-efficacy and professional satisfaction. The current study was undertaken to assess whether the initial access findings were replicated over 4 subsequent implementation phases and to explore the practicality of broad dissemination of the BHIP model.

METHODS
After phase 1, BHIP was extended over 4 subsequent phases in a stepped-wedge design to 46 additional pediatric practices, for a total cohort of 59 practices (354 PCPs serving &gt;300 000 patients). Program components comprised BH education and consultation and support for integrated practice transformation; these components facilitated on-site BH services by an interprofessional BH team. Outcomes were assessed quarterly, preprogram and postprogram launch.

RESULTS
Across combined phases 1 to 5, BHIP was associated with increased primary care access to BH services (screening, psychotherapy, PCP BH visits, psychotropic prescribing) and performed well across 7 standard implementation outcome domains (acceptability, appropriateness, feasibility, fidelity, adoption, penetration, and sustainability). Emergency BH visits and attention-deficit/hyperactivity disorder prescribing were unchanged.

CONCLUSIONS
These findings provide further support for the potential of integrated care to increase access to BH services in pediatric primary care.

Published: July 2021

AbstractOver the recent years metallic foams have become a popular material due to their unique characteristics like low density coupled with beneficial mechanical properties such as good energy absorption, heat resistance, flame resistance, etc. However, their production processes (foaming) is highly stochastic which results in an inhomogeneous foam structure. Hybrid aluminum foam with closed-cell has been manufactured using direct foaming method coupled with the Taguchi Design of Experiments (DOE). Image analysis has been carried out to determine the average porous area and pore size. The influence of the production parameters (amount of foaming agent added, mixing speed and temperature) on the pore size and the porous area has been analyzed using the statistical Taguchi technique. From the experiments it was seen that the most important control factor for both the pore size and the porous area is the amount of the foaming agent added, followed by temperature and stirring speed. Furthermore, the statistical significance of these manufacturing parameters on the response was also investigated by performing analysis of variance (ANOVA) statistical method.

A Transmedia Turn in Educational Strategies: Storytelling in Teaching Literature to School Students
Authors: Arkhangelsky Alexander , Novikova Anna 
Published: July 2021

The article presents theoretical and methodological approaches to using modern media technology in teaching humanities at school. Mediatization of a broad range of cultural practices has altered the mechanisms of cultural memory formation, so school students’ online communication skills should become the foundation of literary education to achieve a balance between tradition and modernization. Transmedia educational strategies proposed in the article allow implementing the principles of humanistic education in teaching humanities subjects. Narration, in its turn — as a method associated with the Russian tradition of teaching literary arts — allows applying the findings of modern semiotic, narratological, and media studies to promote the development of pedagogical practices. In narrative-based learning, the literary text becomes the core of a transmedia project, in which the teacher and students act as directors using various media formats to construct their own narratives on the basis of the writer’s script. Transmedia adaptation of literary classics helps students reconceptualize characters’ ambitions and values, develop creative and critical thinking skills, and get a better understanding of historical and everyday contexts. Cross-platform engagement invokes multiple layers of meaning and artistry, immersing all project participants — students as well as teachers — into a common space of communication, aesthetic experience, and mutual learning, if necessary. Examples illustrating the strategy proposed include educational projects developed with our immediate participation, from our own literature textbook to multimedia projects, in particular the one based on Ivan Goncharov’s Oblomov for the Live Pages project and the one based on Leo Tolstoy’s works as part of the Digital Tolstoy initiative.
The resolution of seismic instruments used in treaty verification research
Authors: Herrin Eugene 
Published: July 2021

abstractThe resolution of the seismic sensors discussed in this paper is limited either by the self-noise of the system or the ambient ground noise at the observing site. The resolution limits of a particular system are frequency dependent. A major objective of the designer is to insure that seismic sensors are available which will be limited in resolution only by the ambient background noise at the quietest sites over the frequency band of interest in treaty verification research. This paper presents a review of the data currently available on the limiting resolution of the most advanced instruments used in this research program.
Steady-state response of an elastic half-space to a moving dislocation of finite width
Authors: Enrique Luco J. , Anderson John G. 
Published: July 2021

abstractAn analytical method to evaluate the transient response on the surface of an elastic half-space for a kinematic dislocation over an infinitely long fault of finite width and arbitrary dip is presented. The model includes finite rupture velocities in the direction of both the strike and dip of the fault. In this sense, it differs from previous two- and three-dimensional models which typically assume one of these velocities to be infinite. In addition to the effects of the free boundary, the model considers a slip vector in an arbitrary direction. The assumptions of infinite fault length and uniform rupture velocities account for the relative simplicity of the solution which is invariant to an observer moving along the strike of the fault with a speed equal to the rupture velocity. These assumptions limit the applicability of the solution to near-field locations far from the ends of realistic faults. A limited set of numerical results illustrating the types of pulse shapes obtained by use of this model, and, some tests to validate the derivation and the numerical results are presented.
An error analysis of frequency-time analysis
Authors: Feng Chi-Chin , Teng Ta-liang 
Published: July 2021

abstractThe temporal resolution and accuracy of frequency-time analysis (FTAN) as applied to surface-wave dispersion analysis are examined for a period range from 10 to 200 sec. The constant relative bandwidth filter (Dziewonski et al., 1969), optimum bandwidth filter (Inston et al., 1971), and display-equalized filter (Nyman and Landisman, 1977) are carefully examined with respect to their adequacy of application over a broad period range. Among these Gaussian filters, the optimum bandwidth filter gives a better performance for relatively short-period (less than 50 sec) dispersion measurement. To measure surface-wave dispersion for a broad period range, a “matched-filter FTAN” technique is introduced by modifying the “residual dispersion measurement” technique (Dziewonski et al., 1972). A detailed numerical analysis is made on this new technique; the result demonstrates a significant improvement on both the resolution and the accuracy of surface-wave dispersion data extraction over a broad period range up to at least 200 sec.
Application of image enhancement and pattern recognition algorithms to seismic reflection data
Authors: McMechan George A. 
Published: July 2021

abstract
A digital seismic reflection section may be converted to a gray scale image composed of pixels and processed with techniques borrowed from the disciplines of image enhancement and pattern recognition. Types of processing include scaling, thresholding, density equalization, filtering, segmentation, and edge-finding. These are successfully applied to a migrated common mid-point seismic reflection line that traverses the Queen Charlotte fault (located in the northeastern Pacific Ocean). The result is the definition and enhancement of an elongated, near-vertical reflectivity anomaly associated with the Queen Charlotte fault.
