Speaker identification in courtroom contexts - Part III: Groups of collaborating listeners compared to forensic voice comparison based on automatic-speaker-recognition technology.

Expert testimony is only admissible in common-law systems if it will potentially assist the trier of fact. In order for a forensic-voice-comparison expert's testimony to assist a trier of fact, the expert's forensic voice comparison should be more accurate than the trier of fact's speaker identification. "Speaker identification in courtroom contexts - Part I" addressed the question of whether speaker identification by an individual lay listener (such as a judge) would be more or less accurate than the output of a forensic-voice-comparison system that is based on state-of-the-art automatic-speaker-recognition technology. The present paper addresses the question of whether speaker identification by a group of collaborating lay listeners (such as a jury) would be more or less accurate than the output of such a forensic-voice-comparison system. As members of collaborating groups, participants listen to pairs of recordings reflecting the conditions of the questioned- and known-speaker recordings in an actual case, confer, and make a probabilistic consensus judgement on each pair of recordings. The present paper also compares group-consensus responses with "wisdom of the crowd" which uses the average of the responses from multiple independent individual listeners.

How the practice of Mindfulness influences the treatment of patients with chronic non-cancer pain associated or not with other therapies: systematic review / Como a prática de Mindfulness influencia no tratamento de pacientes com dor crônica não oncológica associado ou não a outras terapias: revisão sistemática

ABSTRACT BACKGROUND AND OBJECTIVES: Chronic pain has a significant impact on patients' quality of life and the use of drug therapy is often insufficient. Therapies based on Mindfulness come in different forms and have been used as a strategy to manage this condition. Practices can guide attention to the present, help reinterpret pain and improve physical and emotional control skills via the cingulate cortex, somatosensory cortex, parietal operculum, cuneus, and anterior insula. This study seeks to evaluate the results of Mindfulness in terms of its influence on the quality of life of patients with chronic non-cancer pain and the neural changes that this practice promotes, such as greater or lesser activation or variation in size of areas as insula and cingulate cortex, and how these interfere with the perception of pain, with the aim of verifying the applicability of Mindfulness as a complementary method to treatment in this group of patients. CONTENTS: Systematic Review submitted to PROSPERO datadase under number 359011. The search was carried out in the Pubmed, Medline, LILACS and DIALNET databases between 2019 and 2022 with the descriptors and Boolean operator [(MINDFULNESS) AND (CHRONIC PAIN)]. The selection of articles includes randomized clinical trials, cohort studies and case control studies in English, Spanish and Portuguese languages. The risk of bias was assessed using ROB2 and the quality of evidence using GRADE. After analysis, ten studies were assessed as essential for this review. Articles that addressed Mindfulness intervention for chronic pain that responded and added information to the research question were included and articles that did not focus on "Mindfulness" and "chronic pain", studies without free access and texts whose results were not published up to the date of the search were excluded. To analyze Mindfulness therapies, the majority of studies cover more than 50 patients and use scales such as the Brief Pain Inventory (BPI-DPN Q4), Patient Global Impression of Change (PGIC), Five Facet Mindfulness Questionnaire (FFMQ), Chronic Pain Acceptance Questionnaire (CPAQ) and Pain Catastrophizing Scale (PCS). CONCLUSION: The practice of Mindfulness can reduce chronic pain and improving its perception, acceptability and quality of life by enabling the reduction of suffering, anxiety and stress associated with pain through neural changes. As there are limitations in the studies regarding the specific target population and standardization of assessment, it is recommended that future articles address the practice in children, the elderly and athletes with chronic pain, in addition to a detailed methodology to evaluate and promote the sessions. It should be noted that Mindfulness is not a cure for chronic pain, however it presents safety and effectiveness in its different application protocols, with a level of evidence similar to cognitive behavioral therapy.

RESUMO JUSTIFICATIVA E OBJETIVOS: A dor crônica tem um impacto significativo na qualidade de vida dos pacientes e o uso de terapia farmacológica muitas vezes é insuficiente. As terapias baseadas em Mindfulness (Atenção Plena) apresentam-se de diversas formas e têm sido utilizadas como estratégia no manejo dessa condição. As práticas podem conduzir a atenção ao presente, auxiliar na reinterpretação da dor e aprimorar habilidades de controle físico e emocional via córtex cingulado, somatossensorial, opérculo parietal, cúneo e ínsula anterior. O objetivo deste estudo foi avaliar a Mindfulness quanto a sua influência na qualidade de vida dos pacientes com dor crônica não oncológica e as alterações neurais que essa prática promove, como maior ou menor ativação ou variação de tamanho de áreas como a ínsula e córtex cingulado, e como estas interferem na percepção da dor, tendo como finalidade verificar a aplicabilidade da Atenção Plena como método complementar ao tratamento nesse grupo de pacientes. CONTEÚDO: Revisão Sistemática submetida no banco de dados PROSPERO sob o número 359011. Realizou-se a busca nas bases de dados Pubmed, Medline, LILACS e DIALNET entre 2019 e 2022 com os descritores e operador booleano [(MINDFULNESS) AND (CHRONIC PAIN)]. Incluiu-se na seleção de artigos ensaios clínicos randomizados, estudos de coorte e estudos de caso controle nos idiomas inglês, espanhol e português. O risco de viés foi avaliado pelo ROB2 e a qualidade de evidência por meio do GRADE. Após análise, 10 estudos foram avaliados como essenciais para esta revisão. Foram incluídos os artigos que abordavam intervenção em Mindfulness para dor crônica que responderam e agregaram informações à pergunta da pesquisa e excluídos os artigos que não possuem o foco em "Mindfulness" e "dor crônica", estudos sem livre acesso e textos cujos resultados não foram publicados até a data da busca. Para analisar as terapias de Mindfulness, os estudos, em sua maioria, abordam mais de 50 pacientes e usam escalas como o Brief Pain Inventory (BPI-DPN Q4), Patient Global Impression of Change (PGIC), Five Facet Mindfulness Questionnaire (FFMQ), Chronic Pain Acceptance Questionnaire (CPAQ) e Pain Catastrophizing Scale (PCS). CONCLUSÃO: A prática de Mindfulness é capaz de diminuir a dor crônica e melhorar sua percepção, aceitabilidade e qualidade de vida ao possibilitar a redução do sofrimento, ansiedade e estresse associados à dor por meio de alterações neurais. Por haver limitações nos estudos com relação à população-alvo específica e à padronização de avaliação, recomenda-se que artigos futuros abordem a prática em crianças, idosos e atletas com dor crônica, além de metodologia detalhada para avaliar e promover as sessões. Ressalta-se que a Mindfulness não é uma cura para a dor crônica, no entanto apresenta segurança e eficácia em seus diferentes protocolos de aplicação, com nível de evidência similar à terapia cognitiva comportamental.

Biosorption of Pb(II) Using Natural and Treated Ardisia compressa K. Leaves: Simulation Framework Extended through the Application of Artificial Neural Network and Genetic Algorithm.

This study explored the effects of solution pH, biosorbent dose, contact time, and temperature on the Pb(II) biosorption process of natural and chemically treated leaves of A. compressa K. (Raw-AC and AC-OH, respectively). The results show that the surface characteristics of Raw-AC changed following alkali treatment. FT-IR analysis showed the presence of various functional groups on the surface of the biosorbent, which were binding sites for the Pb(II) biosorption. The nonlinear pseudo-second-order kinetic model was found to be the best fitted to the experimental kinetic data. Adsorption equilibrium data at pH = 2-6, biosorbents dose from 5 to 20 mg/L, and temperature from 300.15 to 333.15 K were adjusted to the Langmuir, Freundlich, and Dubinin-Radushkevich (D-R) isotherm models. The results show that the adsorption capacity was enhanced with the increase in the solution pH and diminished with the increase in the temperature and biosorbent dose. It was also found that AC-OH is more effective than Raw-AC in removing Pb(II) from aqueous solutions. This was also confirmed using artificial neural networks and genetic algorithms, where it was demonstrated that the improvement was around 57.7%. The nonlinear Langmuir isotherm model was the best fitted, and the maximum adsorption capacities of Raw-AC and AC-OH were 96 mg/g and 170 mg/g, respectively. The removal efficiency of Pb(II) was maintained approximately after three adsorption and desorption cycles using 0.5 M HCl as an eluent. This research delved into the impact of solution pH, biosorbent characteristics, and operational parameters on Pb(II) biosorption, offering valuable insights for engineering education by illustrating the practical application of fundamental chemical and kinetic principles to enhance the design and optimization of sustainable water treatment systems.

Removal of pharmaceuticals and personal care products from wastewater via anodic oxidation and electro-Fenton processes: current status and needs regarding their application.

This review provides a current opinion on the most recent works that have been published toward the application of electrochemical advance oxidation processes (EAOPs) for the degradation of pharmaceutical and personal care products (PPCPs) in water streams. Advances in the application of anodic oxidation (AO)- and electro-Fenton (EF)-based processes are reported, including operational conditions, electrode performance, and removal. Although AO- and EF-based processes can easily reach 100% removal of PPCPs, mineralization is desirable to avoid the generation of potential toxic byproducts. The following section exploring some techno-economic aspects of the application of EAOPs is based on electrode selection, operational costs as well as their use as cotreatments, and their synergistic effects. Finally, this short review ends with perspectives about the emerging topics that are faced by these technologies applied for the degradation of PPCPs in research and practice.

Speaker identification in courtroom contexts - Part II: Investigation of bias in individual listeners' responses.

In "Speaker identification in courtroom contexts - Part I" individual listeners made speaker-identification judgements on pairs of recordings which reflected the conditions of the questioned-speaker and known-speaker recordings in a real case. The recording conditions were poor, and there was a mismatch between the questioned-speaker condition and the known-speaker condition. No contextual information that could potentially bias listeners' responses was included in the experiment condition - it was decontextualized with respect to case circumstances and with respect to other evidence that could be presented in the context of a case. Listeners' responses exhibited a bias in favour of the different-speaker hypothesis. It was hypothesized that the bias was due to the poor and mismatched recording conditions. The present research compares speaker-identification performance between: (1) listeners under the original Part I experiment condition, (2) listeners who were informed ahead of time that the recording conditions would make the recordings sound more different from one another than had they both been high-quality recordings, and (3) listeners who were presented with high-quality versions of the recordings. Under all experiment conditions, there was a substantial bias in favour of the different-speaker hypothesis. The bias in favour of the different-speaker hypothesis therefore appears not to be due to the poor and mismatched recording conditions.

Processing and Physicochemical Properties of Magnetite Nanoparticles Coated with Curcuma longa L. Extract.

In this work, Curcuma longa L. extract has been used in the synthesis and direct coating of magnetite (Fe3O4) nanoparticles ~12 nm, providing a surface layer of polyphenol groups (-OH and -COOH). This contributes to the development of nanocarriers and triggers different bio-applications. Curcuma longa L. is part of the ginger family (Zingiberaceae); the extracts of this plant contain a polyphenol structure compound, and it has an affinity to be linked to Fe ions. The nanoparticles' magnetization obtained corresponded to close hysteresis loop Ms = 8.81 emu/g, coercive field Hc = 26.67 Oe, and low remanence energy as iron oxide superparamagnetic nanoparticles (SPIONs). Furthermore, the synthesized nanoparticles (G-M@T) showed tunable single magnetic domain interactions with uniaxial anisotropy as addressable cores at 90-180°. Surface analysis revealed characteristic peaks of Fe 2p, O 1s, and C 1s. From the last one, it was possible to obtain the C-O, C=O, -OH bonds, achieving an acceptable connection with the HepG2 cell line. The G-M@T nanoparticles do not induce cell toxicity in human peripheral blood mononuclear cells or HepG2 cells in vitro, but they can increase the mitochondrial and lysosomal activity in HepG2 cells, probably related to an apoptotic cell death induction or to a stress response due to the high concentration of iron within the cell.

Speaker identification in courtroom contexts - Part I: Individual listeners compared to forensic voice comparison based on automatic-speaker-recognition technology.

Expert testimony is only admissible in common law if it will potentially assist the trier of fact to make a decision that they would not be able to make unaided. The present paper addresses the question of whether speaker identification by an individual lay listener (such as a judge) would be more or less accurate than the output of a forensic-voice-comparison system that is based on state-of-the-art automatic-speaker-recognition technology. Listeners listen to and make probabilistic judgements on pairs of recordings reflecting the conditions of the questioned- and known-speaker recordings in an actual case. Reflecting different courtroom contexts, listeners with different language backgrounds are tested: Some are familiar with the language and accent spoken, some are familiar with the language but less familiar with the accent, and others are less familiar with the language. Also reflecting different courtroom contexts: In one condition listeners make judgements based only on listening, and in another condition listeners make judgements based on both listening to the recordings and considering the likelihood-ratio values output by the forensic-voice-comparison system.

Wellbeing of School Communities in the Context of COVID-19 Pandemic: A Qualitative Study in Chilean Low-SES Schools.

The COVID-19 pandemic continues to impact schools and how education is conveyed to students. One of the aspects that has gained strength is supporting the wellbeing of educational communities. The purpose of this study was to describe and understand the construction of school wellbeing during the pandemic, based on the notion of collective and sustainable wellbeing. Through a qualitative design, we conducted a study in four Chilean low-SES schools in which a national school mental health program is implemented. A total of 41 in-depth interviews and one group interview were conducted with students, parents, teacher, teacher assistants, school principals, psychosocial professionals, and the school mental health officers during the second half of the 2020 school year. Thematic content analyses showed that, while facing the school closure challenges, schools strived to protect students' and teachers' wellbeing. However, participants highlighted necessary conditions for sustaining the school community's wellbeing and mental health in the context of the COVID-19 pandemic: assuring digital connectivity for all students; coordinated work with families and within the school; strengthening networks; curriculum adaptation and diversified pedagogical strategies; and emotional support toward teachers, families, and students. We discuss these findings and their implications for a sustainable and collective perspective of the wellbeing of school communities in low-SES schools, as well as for policy, practice, and research from the perspective of schools for social justice and health promotion.

Pharmaceuticals and personal care products in water streams: Occurrence, detection, and removal by electrochemical advanced oxidation processes.

Pharmaceutical and personal care products (PPCPs) are part of the emerging contaminants (ECs) in the environment due to their known or suspected adverse effects in aquatic and terrestrial organisms, as well as in human health. Presence of PPCPs in aquatic and terrestrial ecosystems has been mainly attributed to the effluents of wastewater treatment plants (WWTPs). Although several PPCPs have been detected in wastewater, their removal from wastewater via biological processes is limited. Removal of PPCPs depends on their chemical structure, concentration, solubility, and technology used to treat the wastewater. Electrochemical Advanced Oxidation Processes (EAOPs) are some of the most sought-after methods for dealing with organic pollutants in water including PPCPs, due to generation of strong oxidants such as •OH, H2O2 and O3- by using directly or indirectly electrochemical technology. This review is focused on the removal of main PPCPs via EAOPs such as, anodic oxidation, electro-Fenton, photoelectron-Fenton, solar photoelectron-Fenton, photoelectrocatalysis and sonoelectrochemical processes. Although more than 40 PPCPs have been identified through different analytical approaches, antibiotics, anti-inflammatory and antifungal are the main categories of PPCPs detected in different water matrices. Application of EAOPs has been centered in the removal of antibiotics and analgesics of high consumption by using model media, e.g. Na2SO4. Photoelectrocatalysis and Electro-Fenton processes have been the most versatile EAOPs applied for PPCPs removal under a wide range of operating conditions and a variety of electrodes. Although EAOPs have gained significant scientific interest due to their effectiveness, low environmental impact, and simplicity, further research about the removal of PPCPs and their by-products under realistic concentrations and media is needed. Moreover, mid-, and long-term experiments that evaluate EAOPs performance will provide knowledge about key parameters that allow these technologies to be scaled and reduce the potential risk of PPCPs in aquatic and terrestrial ecosystem.

Lentil sprouts: a nutraceutical alternative for the elaboration of bread.

The pro-health action of germinated lentils could be useful to be added with wheat flour in the production of box bread. In this work, we spectroscopically evaluate the germinated and non-germinated lentils, and use them at the concentrations of 5 and 10% for the production of box bread. The chemical and physical tests of the bread and its determination of phenolic acids and flavonoids (by HPLC) were also performed. As well as the evaluation of the quality of flour and dough used to produce the bread and the acceptance of the germinated lentil bread with a population of 20 people with diabetes or with diabetic relatives It is shown that: (1) The amplitude of photoacoustic signal obtained by photoacoustic spectroscopy is modified as a function of the percentage of germinated lentil (GL) flour (0, 5 or 10%) add to the bread; being higher the photoacoustic amplitude to higher concentration of GL in the absorption band of 300-425 nm, which is related to higher content of phenols and flavonoids. (2) The contents of phenolic acids (Sinapinic, ß- resorcylic, Chlorogenic and Ferulic) and flavonoids (Quercetin and Isorhamnetin) tended to increase in the germinated lentil bread with 10% concentration of germinated lentil flour with respect to the control bread (0% GL). (3) The addition of germinated lentils flour to 5 and 10% into wheat flour to produce bread with higher hardness and less cohesiveness than bread based on wheat flour only. The Falling number indicate that there is no significant difference between the control sample and the 5% GL flour, while in the 10% GL flour there was a reduction of 21 s, with respect to the control. The effect of the germinated lentil flour percentage on the pasting properties of the flours was significant between the control and 10% GL flour. In general, the quality of the dough and flour are modified due to the addition of germinates lentils, and this affectation increases with the increase in the concentration of GL. (4) The bread added with germinated lentil has sensory acceptance with a group of people with diabetes and/or diabetic relatives in their attributes in general. The obtained results thus support the production of wheat bread with mixed germinated lentils flour, as a nutraceutical option for human consumption.

Improving ozonation to remove carbamazepine through ozone-assisted catalysis using different NiO concentrations.

The carbamazepine (CBZ) abatement is herein evaluated using catalytic ozonation at different NiO concentrations as catalyst: 100, 300, and 500 mg L-1, revealing its total destruction after 5 min of reaction either by conventional or catalytic ozonation. The NiO incorporation in the reactor does not increase the destruction rate, but the catalyst presence enhances the partial mineralization of the contaminant by conversion into oxalic and formic acids and the removal of total organic carbon (TOC) associated with the formation of oxidant species such as hydroxyl radical. Evidence for this behavior is the accumulation rate of the above acids which rise proportionally to the NiO concentration. The highest NiO concentration (500 mg L-1) reached a maximum TOC removal of 79.2%, which exceeds by 50% the outcome of the conventional treatment. The accumulation-decomposition profiles of oxalic and formic acids suggest the occurrence of simultaneous reaction mechanisms (hydroxyl radicals and complex formations) on the catalyst during CBZ ozonation. According to XPS analysis, the presence of nitrogen species in the NiO-ozonated was attributable to byproducts of CBZ decomposition. The toxicity bioassay based on Lactuca sativa seeds demonstrate that ozonated samples attained similar plant germination than the reference substance (water) after 120 min of treatment. This result is comparable with or without the catalyst presence, indicating the formation of non-toxic accumulated byproducts at the end of the ozonation reaction.

Causas del desprendimiento de retina y el desenlace visual final en menores de 18 años en el Hospital San Vicente Fundación / Causes of retinal detachment and visual outcome in children under 18 years old treated at Hospital Universitario de San Vicente Fundación

RESUMEN Objetivo: caracterizar las causas del desprendimiento de retina y determinar la agudeza visual final en menores de 18 años en el Hospital San Vicente Fundación entre 2012 y 2017. Metodología: se realizó un análisis retrospectivo de historias clínicas de pacientes con diagnóstico de desprendimiento de retina confirmado por examen oftalmológico o ecografía, se incluyeron pacientes menores de 18 años que ingresaron al Hospital San Vicente Fundación entre 2012 y 2017 para identificar las causas del desprendimiento de retina y la agudeza visual final. Resultados: se analizaron 51 historias clínicas: 28 hombres y 23 mujeres, 39,1 % ocurrieron en menores de 1 año y no se encontró desprendimiento de retina por encima de los 14 años. Las causas se establecieron como retinopatía de la prematuridad 23,5 %, trauma ocular 21,6 %, retinoblastoma 9,8 %, toxoplasmosis congénita 7,8 %, toxocara 7,8 %, entre otras, no se encontró causa en 3,9 % de los pacientes. En 50 ojos de 41 pacientes se determinó la agudeza visual final, de los cuales 47 (94 %) quedaron con agudeza visual peor o igual a 20/200 y 3 ojos con agudeza visual de 20/40 o mejor. Discusión: el desprendimiento de retina es infrecuente en los niños, sin embargo, sus causas y desenlaces son más devastadores que en los adultos. En nuestro medio las principales causas son la retinopatía de la prematuridad, el trauma, el retinoblastoma y las infecciones parasitarias. Diferente a los adultos, en los niños se requiere una evaluación más cuidadosa y un umbral de sospecha más bajo para considerar enfermedades potencialmente mortales.

SUMMARY Objective: To characterize the causes of retinal detachment and to determinate the visual outcome in children younger than 18 years old evaluated at San Vicente Fundación Hospital between 2012 and 2017. Methodology: We performed a retrospective analysis of medical records of patients with a diagnosis of retinal detachment confirmed by ophthalmological examination or ultrasound scan. Patients under 18 years old admitted to San Vicente Fundación Hospital between 2012 and 2017 were included to identify the causes of retinal detachment and the final visual acuity. Results: 51 clinical histories were analyzed: 28 men and 23 women; 39.1% occurred in children under 1 year old, and no retinal detachment was found above 14 years old. The causes were established as: retinopathy of prematurity 23.5%, ocular trauma 21.6%, retinoblastoma 9.8%, congenital toxoplasmosis 7.8%, toxocara 7.8%, among others. The cause was not found in 3.9% of patients. In 50 eyes of 41 patients, the final visual acuity was determined, of which 47 (94%) had visual acuity equal or worse to 20/200 and 3 eyes with better corrected visual acuity of 20/40 or better. Discussion: Retinal detachment is infrequent in children; however, its causes and outcomes are more devastating than in adults. In our environment, the main causes are retinopathy of prematurity, trauma, retinoblastoma and parasitic infections; unlike adults, children require a more careful assessment and a lower threshold of suspicion to consider life-threatening diseases.

Inhibition effect of ethanol in naproxen degradation by catalytic ozonation with NiO.

This work evaluated the inhibition effect of low molecular weight alcohol (ethanol) on naproxen (NAP) degradation by conventional and catalytic ozonation. The reaction system considered the ethanol as complementary organic matter in water. The conventional ozonation and in the presence of nickel oxide (O3-NiO) achieved 98% NAP degradation during the first 15 min of reaction despite the presence of ethanol. However, NAP degradation presented a delaying effect during the first minutes of treatment with this alcohol. The latter phenomenon indicates that ethanol concentration played a meaningful role in ozonation effectiveness in comparison with the presence of NiO catalyst. The presence of NiO did not generate differences in the byproducts in comparison with conventional ozonation. The intermediates were detected using the Electrospray Ionization Mass Spectrometry technique and have only one aromatic ring in their chemical structure. In samples without ethanol, these byproducts appeared only in the first 5 min of reaction. The TOC study demonstrated the increment of 25% in the mineralization degree with the presence of NiO due to the formation of ·OH species.

Evaluación Cualitativa de un Sistema de Monitoreo de la Convivencia Escolar / Avaliação Qualitativa de um Sistema de Monitoração da Convivência Escolar / Qualitative evaluation of a System for Monitoring School Climate

En el marco de un proyecto para el diseño, desarrollo y validación de un sistema de monitoreo de la convivencia escolar, el presente estudio evalúa dicho sistema a partir de los significados construidos por sus usuarios, con el fin de mejorar acciones futuras. Se realizaron 17 entrevistas grupales en15 escuelas, más una entrevista en profundidad a la Coordinadora Comunal de Convivencia Escolar. Resultados: Las escuelas participantes señalan que el sistema de monitoreo destaca por la entrega de información válida, pues permite la toma de decisiones basadas en evidencia logrando complejizar la mirada que las escuelas tienen de sí mismas. Discusiones: Las escuelas colocan en el centro de la mejora escolar a la propia escuela, y destacanque la efectividad sólo es posible si la priorización de necesidades surge del propio colegio.

As part of a project in which we designed, developed, and validated a monitoring system of school climate, the present study evaluates the system based on the meanings constructed by its users, in order to improve future actions. 17 group interviews in 15 schools, plus an in-depth interview to the Community Coordinator School Coexistence were performed. Results: Participating schools indicate that the highlight of the monitoring system is the delivery of valid information that allow evidence-based decision making processes. This in turn allows schools to construe a more complex view of themselves. Discussions: Schools place, in the center of school improvement, the school itself, and emphasize that effectiveness is only possible if the prioritization of needs arises from the school itself.

Foram realizadas 17 entrevistas grupais em15 escolas, mais uma entrevista em profundidade à Coordenadora Comunal de Convivência Escolar. Resultados: As escolas participantes relatam que o sistema de monitoração destaca pela entrega de informação válida, pois permite a tomada de decisões baseadas em evidência logrando problematizar a olhada que as escolas têm de si mesmas. Discussões: As escolas colocam no centro da melhora escolar a própria escola e destacam que a efetividade só é possível se a priorização de necessidades surge do próprio colégio.

Tissue Damage, Temperature, and pH Induced by Different Electrode Arrays on Potato Pieces (Solanum tuberosum L.).

One of the most challenging problems of electrochemical therapy is the design and selection of suitable electrode array for cancer. The aim is to determine how two-dimensional spatial patterns of tissue damage, temperature, and pH induced in pieces of potato (Solanum tuberosum L., var. Mondial) depend on electrode array with circular, elliptical, parabolic, and hyperbolic shape. The results show the similarity between the shapes of spatial patterns of tissue damage and electric field intensity, which, like temperature and pH take the same shape of electrode array. The adequate selection of suitable electrodes array requires an integrated analysis that involves, in a unified way, relevant information about the electrochemical process, which is essential to perform more efficiently way the therapeutic planning and the personalized therapy for patients with a cancerous tumor.

Terapia electroquímica: relación del patrón espacial del daño tisular con la forma del arreglo de electrodos / Electrochemical therapy: relationship of the tissular damage space pattern with the form of electrodes repair

Se realizó una investigación en la Escuela Superior de Ingeniería Mecánica y Eléctrica del Instituto Politécnico Nacional de Ciudad de México, desde mayo hasta junio de 2016, con el objetivo de determinar cómo cambia el patrón espacial del daño tisular con la forma del arreglo de electrodos en piezas tridimensionales de papa (Solanum tuberosum L) bajo la acción de 10 mA durante 30 min para los arreglos de electrodos con formas colineal, circular, elíptica, parabólica e hiperbólica). Los resultados mostraron la estrecha relación entre el daño tisular y la forma del arreglo de electrodos, así como algunos hallazgos que se observan también en tumores, tales como: necrosis circular alrededor de todos los electrodos, daño tisular extensivo en espacio y en tiempo, burbujeo alrededor del cátodo, zona blanca alrededor del ánodo; igualmente, se observó que las regiones alejadas de los electrodos no se afectaron

An investigation in the Mechanical and Electric Engineering Higher School of the National Polytechnic Institute of Mexico City, was carried out from May to June, 2016, aimed at determining how the tissue damage space pattern changes with the electrodes position form in three-dimensional pieces of potato (Solanum tuberosum L) under the 10 MA action during 30 minutes for electrodes position with cholineal, round, elliptic, parabolic and hyperbolic forms). The results showed a close relationship between the tissue damage and the electrodes position form, as well as some findings that are also observed in tumors, such as: circular necrosis around all the electrodes, extensive tissue damage in space and time, bubbling around the cathode, white area near the anode; likewise, it was observed that the regions far from the electrodes were not affected
