Hacia una risa posthumana y decolonial: Construyendo una risistencia feminista monstruosa en la payasaria
Authors: Lima Caminha Melissa 
Published: July 2020

En las dos últimas décadas, diversas payasas vienen desarrollando un movimiento de visibilización de este tipo cómico, tanto en el circo como en el teatro. Festivales, talleres e investigaciones vienen contribuyendo para escribir la historia doblemente excéntrica de las payasas. Este honorable movimiento, sin embargo, aun parece seguir la misma lógica arquetípica del payaso moderno, heredero de la Ilustración. Este trabajo pone en valor la payasa en tanto cuerpa política fundamental, con el potencial de crear risistencias plurales que puedan deconstruir la figura del payaso moderno y la risa humanista encarnada en su arquetipo. Reconoce la importancia histórica de la payasa, e invita a seguir avanzando en sus políticas artísticas del cuerpo, ahora a partir de una perspectiva feminista posthumanista y decolonial, proponiendo políticas de coaliciones artística y teórica en pro de una democracia de la risa. A través de la creación de figuraciones feministas móviles monstruosas, el proyecto tiene como objetivo animar un movimiento de risistencia a la risa moderna, ilustrada, colonial, humanista y patriarcal.
In the last two decades, various female clowns have been developing a movement of visibility of this comic type, both in the circus and in the theater. Festivals, workshops and research have been contributing to write the doubly eccentric herstories of women in clowning. This honorable movement, however, still seems to follow the same archetypal logic of the modern clown, heir to the Enlightenment. This work values the female clown as a fundamental political body, with the potential to create plural laughters that can deconstruct the figure of the modern clown and the humanistic laugh embodied in its archetype. It recognizes the historical importance of female clowns, and invites a step forward in its artistic body politics, now from a feminist post-humanist and decolonial perspective, proposing artistic and theoretical coalitions in favor of a democracy of laughter. Through the creation of monstrous mobile feminist figurations, the project aims to encourage a movement of laughteresistance at modern, enlightened, colonial, humanistic, and patriarchal laughter.
La desigualdad educativa, ¿son los programas de refuerzo la solución? Evidencia empírica del impacto a nivel intracentros
Authors: Villar-Aldonza Adriano , Gambau-Suelves Borja 
Published: July 2020

El diferente ritmo de aprendizaje entre el alumnado es, y ha sido, un problema tanto para el profesor como para la comunidad educativa y académica en su conjunto. Entre las políticas públicas dirigidas a corregir esta problemática destacan dos: el agrupamiento del alumnado con base en sus capacidades-tracking- y, más recientemente, los programas de refuerzo extraescolares. En este trabajo se evalúa el impacto que, sobre la desigualdad educativa, tuvo un programa de refuerzo implantado de manera voluntaria en los institutos españoles entre 2005 y 2012: el plan PROA. Como medida de aproximación a la desigualdad educativa se ha empleado la brecha en términos de resultados existente entre los alumnos de un mismo centro, así como el índice de desigualdad de Gini. Los resultados obtenidos, a partir de la técnica de Propensity Score Matching, señalan que la aplicación del programa no redujo las diferencias en términos de puntuación entre el alumnado, de igual modo que no aumentaron las calificaciones medias en lectura en aquellos centros que decidieron participar en el programa.
The need to cater to the different learning pace of students still remains a frequent problem for both teachers and the academic community. Among the public policies aimed to solve this problem, two stand out: the grouping of students based on their abilities -tracking- and, more recently, the extracurricular reinforcement programs. This paper evaluates the impact that the PROA, a reinforcement program implemented on a voluntary basis by different High Schools in Spain between 2005 and 2012, had on educational inequality. To measure educational inequality, the gap in terms of results between the students of the same school has been used, as well as the Gini inequality index. The results obtained, which are based on the Propensity Score Matching technique, indicate that the implementation of this program did not bridge the gap in terms of marks between students. They also suggest that average reading scores did not increase in those schools that decided to participate in the program.

Published: July 2020

This article presents a comprehensive study of an odd Lindley-Gompertz distribution which has already been proposed in the literature but without any properties. The present study unlike the previous one has considered the derivation of several properties of the odd Lindley-Gompertz distribution with their graphical representations and discussions which has not been done in the first proposition of the distribution. The study looks at properties such as survival (or reliability) function, the hazard function, the cumulative hazard function, the reverse hazard function, the odds function, quantile function, moments, moment generating function, characteristic function, cumulant generating function, distribution of order statistics and maximum likelihood estimation of the distribution’s parameters none of which was treated by the previous author of the model. An illustration to evaluate the goodness-of-fit of the odd Lindley-Gompertz distribution has also been done using two real life datasets and the results show that the model fits the datasets better than the five other distributions considered in this present study.

Aim: To review from the literature, in a narrative way, techniques used for hemorrhoidectomy as well as benefits and criticisms about the procedures.
Methodology: For this purpose, a descriptive literary review was carried out for the construction of the work. In view of what is found, it is possible to assess this according to an epidemiological study conducted in the United States.
Results: Hemorrhoid disease is a very common condition, occurring in 4.4% of adults, with a maximum prevalence between 45 and 65 years. The etiology of hemorrhoids is still unknown. Hemorrhoidectomy is believed to be the best treatment option for symptomatic hemorrhoid disease grade III and IV. The techniques used present advantages and disadvantages for the patient, since it will depend on the surgeon to choose the best approach and surgical procedure.
Conclusion: It is observed that more risk and benefit assessments are needed than the technique used in hemorrhoidectomy, based on randomized studies with a significant number of patients included in the study.

Published: July 2020

Background/Aim: Overall patients’ satisfaction with services provided in a hospital is an objective of care, and also a desired outcome. Dissatisfied patients are more likely not to comply with prescriptions, follow-up appointments, or further use the health facility. Services provided in public health facilities in Nigeria have been perceived by both patients and health care providers as being poor. Teaching hospitals in Nigeria are the apex referral centers, with the General Outpatient Department (GOPD) being the first unit that patients mostly go to first. Waiting time and attitude of health workers are key contributors to overall patients’ satisfaction. The objective of this study is to assess patients’ satisfaction with waiting time, and attitude of health workers in the GOPD of a Teaching hospital in Nigeria.
Materials and Methods: Cross-sectional study, conducted over three months in 2017 at the GOPD of Enugu State University Teaching Hospital, Nigeria. Structured, interviewer-administered questionnaire was used. Exit interview was conducted on randomly selected 13 patients as they were leaving the GOPD Pharmacy unit on Tuesdays and Thursdays of every week, until 313 respondents were interviewed.
Results: A total of 313 patients were interviewed, 131 (41.9%) males and 182 (58.1%) females. Analysis was done using Statistical Package for Social Sciences (SPSS) version 21.0, and the results were expressed as percentages. Patients’ satisfaction score for the various items studied were found to be 53.7% for waiting time, 74.4% for attitude of Records staff, 78.3% for nurses, 71.9% for doctors, 70.6% for time spent with doctor, 72.5% with doctor's explanation and 40.6% with privacy.
Conclusions: Overall satisfaction with services rendered at the GOPD was 60.4%. Identifying and implementing interventions that will enhance patients satisfaction, shall improve health facility utilization.

Published: July 2020

Background and Objective: Modified-release tablet of theophylline that can increase its usefulness despite narrow therapeutic index and short half-life, is being formulated. However, the rate and extent of release of a sustained-release delivery system can be affected by some factors. This work is aimed at investigating the effect of agitation rates and pH of dissolution medium on release kinetics of sustained-release theophylline tablet formulated using hydrophilic polymers.
Materials and Methods: Theophylline granules was formulated using 3 polymers (HPMC, SCMC and Sodium alginate) to form 3 batches of granule by wet granulation method, using 95% ethanol. The granules compacted to batches of sustained-release matrix tablets. The tablet batches were characterized for tablet properties, and dissolution studies carried out using simulated gastric and intestinal fluid separately at different agitation rates. The data from dissolution studies were subsequently fitted into 4 drug release kinetics models.
Results: The swelling of the 3 polymers over time was noteworthy, although there was no significant difference between them. The release kinetic followed the Higuchi model and zero-order releasing more than 90% over 8 hours period, with t10 and t90 released at 14 minutes and 6.8 hours respectively. The mechanical properties of the tablets were within the acceptable limit.
Conclusion: The agitation rate and pH of the medium had no significant effect on the release of the theophylline from the batches of matrix tablets except in the case of F1 which showed a marginally significant effect.
Genetic Diagnosis of Glaucoma
Authors: Mahmoud Hany , Hashim Marwa S. 
Published: July 2020

Purpose: Glaucoma, the most prevalent cause of irreversible blindness across the world, is progressive optic nerve degeneration and affection (neuropathy) caused by a mixture of both genetic and environmental factors [1]. The extracellular matrix (ECM) structure of the trabecular Meshwork TM has a major role in intraocular pressure IOP control. Transforming growth factor beta (TGF-β) is a growth factor that plays major roles in cellular functions, including encouraging extracellular matrix synthesis and vascular angiogenesis. TGFβ2 treatment of TM cells alters ECM components [8] and induces ECM bonds.
Aim of the Study: To study the relationship between family history and glaucoma according to genotype and genetic polymorphism.
Methods: Blood collection and DNA extraction Genotyping: TGFB2 Rs99196 genotyping was done using TaqMan SNP genotyping Assay (ID C___8853564_10). StepOne real time PCR system (Applied Biosystem, Ca, USA) was used for amplifiction.
Statistical Analysis: The sample size of the study group was calculated using a program at (www.openepi.com/SampleSize/ SSCC.htm).
Results: Important genotype differences frequencies were detected between the positive family history and negative family history groups for the codominant, dominant, recessive and overdominant inheritance models.
Conclusion: This study recommends that other polymorphisms of genes associated with glaucoma and the analysis of these gene products and their relationship with disease risk factors should be more studied.
Optic disc dose reduction in ocular brachytherapy using 125I notched COMS plaques: A simulation study based on current clinical practice
Authors: Lee Yongsook C. , Lin Shih‐Chi , Kim Yongbok 
Published: July 2020

AbstractPurposeAlthough notched Collaborative Ocular Melanoma Study (COMS) plaques have been widely used, optic disc dose reduction by notched COMS plaques has not been discussed in the literature. Therefore, this study investigated optic disc dose reduction in ocular brachytherapy using 125I notched COMS plaques in comparison with optic disc dose for 125I standard COMS plaques.MethodsFor this simulation study, an in‐house brachytherapy dose calculation program was developed using MATLAB software by incorporating the American Association of Physicists in Medicine Task Group‐43 Update (AAPM TG‐43U1) dosimetry formalism with a line source approximation in a homogeneous water medium and COMS seed coordinates in the AAPM TG 129. Using this program, optic disc doses for standard COMS plaques (from 12 to 22 mm in diameter in 2 mm increments) and notched COMS plaques with one seed removed (Case #1, from 12 to 22 mm) and with two seeds removed (Case #2, from 14 to 22 mm) were calculated as a function of tumor margin‐to‐optic disc distance (DT) for various tumor basal dimensions (BDs) for prescription depths from 1 to 10 mm in 1 mm intervals. A dose of 85 Gy for an irradiation time of 168 h was prescribed to each prescription depth. Then absolute and relative optic disc dose reduction by notched COMS plaques (Cases #1 and #2) was calculated for all prescription depths.ResultsOptic disc dose reduction by notched COMS plaques (Cases #1 and #2) had five unique trends related to maximum optic disc dose reduction and corresponding optimal DT for each BD in each plaque. It increased with increasing prescription depth.ConclusionsThe results presented in this study would enable the clinician to choose an adequate plaque type among standard and notched 125I COMS plaques and a prescription depth to minimize optic disc dose.
Creating nonbelieved memories for bizarre actions using an imagination inflation procedure

Published: July 2020

SummaryThe current experiments examined the creation of nonbelieved true and false memories after imagining bizarre and familiar actions using the imagination inflation procedure (Goff & Roediger, 1998). In both experiments, participants took part in three sessions. In Session 1, participants had to perform or imagine simple familiar actions (e.g., “stir the water with the spoon”) and bizarre actions (e.g., “balance the spoon on your nose”). A day later, participants needed to imagine simple actions of which some were new actions, and some were old actions that appeared in the first session. After a week, the participants completed a recognition task. For those actions that were correctly or incorrectly remembered as having been performed, the participant was challenged that the action was not performed in order to evoke nonbelieved true and false memories. In general, we found that the imagination inflation procedure can successfully induce participants to produce nonbelieved memories. In Study 1, we successfully induced nonbelieved memories for bizarre actions, although in general nonbelieved memory rates were low. In Study 2, more participants formed nonbelieved memories for bizarre actions than for familiar actions. Also, we found that especially belief was more susceptible to revision when memories were challenged than recollection. In two experiments, we showed that nonbelieved memories can successfully be induced for both familiar and bizarre actions.

AbstractAqueous dual‐ion batteries (DIBs) are promising for large‐scale energy storage due to low cost and inherent safety. However, DIBs are limited by low capacity and poor cycling of cathode materials and the challenge of electrolyte decomposition. In this study, a new cathode material of nitrogen‐doped microcrystalline graphene‐like carbon is investigated in a water‐in‐salt electrolyte of 30 m ZnCl2, where this carbon cathode stores anions reversibly via both electrical double layer adsorption and ion insertion. The (de)insertion of anions in carbon lattice delivers a high‐potential plateau at 1.85 V versus Zn2+/Zn, contributing nearly 1/3 of the capacity of 134 mAh g−1 and half of the stored energy. This study shows that both the unique carbon structure and concentrated ZnCl2 electrolyte play critical roles in allowing anion storage in carbon cathode for this aqueous DIB.

Published: July 2020

AbstractTumor hypoxia and chemoresistance are long‐lasting challenges in clinical cancer treatments resulting in treatment failures and low patient survival rates. Application of phototherapies to treat deep tissue‐buried tumors has been hampered by the lack of near infrared photosensitizers, and consumption of tissue oxygen, worsening the tumor hypoxia problem. Herein, an unprecedented theranostic lanthanum hexaboride‐based nanodrug is engineered to act as bimodal computed tomographic/magnetic resonance imaging contrast agents, absorb long near infrared (NIR) light in the biological window IIb (1500–1700 nm), generate hydroxyl radicals without using oxygen, and destroy drug‐resistant NCI‐H23 lung tumors completely, leading to an amazingly long average half‐life of 180 days, far exceeding than those of doxorubicin‐treated (21 days) and untreated mice groups (13 days). This work pioneers the field of photodynamic therapy in conquering hypoxia and chemodrug resistance problems for NIR‐IIb oxygen‐independent cancer treatments.

Published: July 2020

AbstractSelf‐powered arbitrary motion sensors are in high demand in the field of autonomous controlled systems. In this work, a magnetic repulsion‐assisted self‐powered motion sensor is integrated with a hybrid nanogenerator (MRSMS–HNG) as a battery‐less arbitrary motion sensing system. The proposed device can efficiently detect the motion parameters of a moving object along any arbitrary direction and simultaneously convert low frequency (<5 Hz) vibrations into useful electricity. The MRSMS–HNG consists of a central magnet for the electromagnetic (EMG)–triboelectric (TENG) nanogenerator and four side magnets for motion sensors. Because all the magnets are aligned in the same magnetization direction, the repulsive force owing to the movement of the central magnet actuates the side magnets to achieve self‐powered arbitrary motion sensing. These self‐powered motion sensors exhibit a high sensitivity of 981.33 mV g−1 under linear motion excitation and have a tilting angle sensitivity of 9.83 mV deg−1. The proposed device can deliver peak powers of 27 mW and 56 µW from the EMG and TENG, respectively. By integrating the self‐powered motion sensors and hybrid nanogenerator on a single device, real‐time wireless transmission of motion sensor data to a smartphone is successfully demonstrated, thus realizing a battery‐less arbitrary motion‐sensing system for future autonomous control applications.
A Polymer/Carbon‐Nanotube Ink as a Boron‐Dopant/Inorganic‐Passivation Free Carrier Selective Contact for Silicon Solar Cells with over 21% Efficiency
Authors: Chen Jianhui , Wan Lu , Li Han , Yan Jun , Ma Jikui , Sun Biao , Li Feng , Flavel Benjamin S. 
Published: July 2020

AbstractTraditional silicon solar cells extract holes and achieve interface passivation with the use of a boron dopant and dielectric thin films such as silicon oxide or hydrogenated amorphous silicon. Without these two key components, few technologies have realized power conversion efficiencies above 20%. Here, a carbon nanotube ink is spin coated directly onto a silicon wafer to serve simultaneously as a hole extraction layer, but also to passivate interfacial defects. This enables a low‐cost fabrication process that is absent of vacuum equipment and high‐temperatures. Power conversion efficiencies of 21.4% on an device area of 4.8 cm2 and 20% on an industrial size (245.71 cm2) wafer are obtained. Additionally, the high quality of this passivated carrier selective contact affords a fill factor of 82%, which is a record for silicon solar cells with dopant‐free contacts. The combination of low‐dimensional materials with an organic passivation is a new strategy to high performance photovoltaics.

AbstractPCPDTBT‐SO3K (CPE‐K), a conjugated polyelectrolyte, is presented as a mixed conductor material that can be used to fabricate high transconductance accumulation mode organic electrochemical transistors (OECTs). OECTs are utilized in a wide range of applications such as analyte detection, neural interfacing, impedance sensing, and neuromorphic computing. The use of interdigitated contacts to enable high transconductance in a relatively small device area in comparison to standard contacts is demonstrated. Such characteristics are highly desired in applications such as neural‐activity sensing, where the device area must be minimized to reduce invasiveness. The physical and electrical properties of CPE‐K are fully characterized to allow a direct comparison to other top performing OECT materials. CPE‐K demonstrates an electrical performance that is among the best reported in the literature for OECT materials. In addition, CPE‐K OECTs operate in the accumulation mode, which allows for much lower energy consumption in comparison to commonly used depletion mode devices.
