Authors: Narimanpour Atefeh , Ghaneian Mohammad Taghi , Ehrampoosh Mohammad Hassan 
Published: June 2022

Introduction: One of the worrying and increasing environmental problems is urban and industrial waste water pollution, such as chromium (Cr). Given the destructive effects of Cr and non-degradability, its removal is of great importance. Adsorption method by low-cost biosorbents has been a successful method in during the last decade. This study aims to examine the effect of usual and acid-modified fig leaves powder as a biosorbent for removing of Cr (VI) from a synthetic aqueous solution.
Methods: Laboratory tests were designed and implemented, including solution making of Cr (VI) and then in order to study the effect of different parameters, including solution pH, contact time, solution concentration, and adsorbent dosage, the secondary amount of chromium concentration was measured and compared by atomic absorption spectrometer.
Results: The results showed that for usual adsorbent, optimum parameters included pH 2, 200mg/l initial concentration, 40g adsorbent concentration, and 120min equilibrium time while for the modified adsorbent, optimum parameters were pH 3, 300mg/l initial concentration, 40g adsorbent concentration, and 120min equilibrium time. The maximum adsorption percentage of Cr (VI) in the first case was 54.33% and in the second case was 91.50%. In addition, by examining adsorption isotherms and kinetic models, it was found that Cr adsorption in both cases follows Langmuir isotherm (R2=0.942 for usual and R2=0.975 for modified adsorbent) and pseudo-second order kinetic model (R2=0.976 for usual and R2=0.982 for modified adsorbent).
Conclusion: More efficient removal of Cr using a modified adsorbent compared to usual adsorbent and previous studies indicates the suitability of modified fig leaves powder as an adsorbent of Cr (VI).

Published: June 2022

Si bien la imposición de requisitos de salud (RS) no es un elemento nuevo en el control de las migraciones contemporáneas y no contemporáneas. Si es un dispositivo biotecnopolítico recurrente en diferentes países para gestionar la gobernanza de la migración y la salud al operar como un filtro que privilegia ciertos cuerpos migrantes sobre otros. En Australia, desde hace décadas existe una extensa infraestructura de vigilancia que relaciona migración, salud, discapacidad y raza, que reproduce, por un lado, una geopolítica del riesgo que sitúa al sur global en desventaja. Y, por otro lado, articula un complejo sistema de seguimiento a nivel global a través de dispositivos de vigilancia informática que operan en complicidad con otros estados receptores de migraciones como Canadá, Estados Unidos, Nueva Zelanda y el Reino Unido. El objetivo de este estudio es utilizar el caso australiano como referencia para analizar las posibles consecuencias de imponer un «pasaporte de vacunación» como requisito sanitario global bajo el régimen de COVID-19.

El derecho humano a la vivienda entre la población inmigrante en España
Authors: Estrada Villaseñor Cecilia , Rodríguez Calles Luis 
Published: June 2022

El artículo presenta un análisis sobre el acceso a la vivienda de los inmigrantes en España desde una perspectiva de los derechos humanos. Este colectivo que reside en barrios y municipios españoles tiende a concentrarse en determinadas zonas de viviendas baratas y degradadas y que, consecuentemente, terminan siendo estigmatizadas por la población nativa. No en vano, los inmigrantes encuentran especiales dificultades para acceder a una vivienda digna por una serie de cuestiones, pero, fundamentalmente por una situación económica precaria derivada, en algunos casos, de la ausencia de políticas públicas eficaces y de las actitudes excluyentes por parte de los propietarios y arrendatarios de vivienda. Sobre este último punto, se propone un análisis a tres niveles para el estudio de la exclusión social: el Estado, el mercado y la sociedad civil, (macro, meso y micro) para observar así la influencia de estos agentes en el grado de cumplimiento del derecho humano a la vivienda que experimenta el colectivo inmigrante en España.

Authors: Molina-Hernández Pablo José , Castro-Badilla Guillermo , Guzmán-Hernández Tomás de Jesús 
Published: June 2022

Para el secado y deshidratación de productos agrícolas, el Instituto Tecnológico de Costa Rica, Campus Local San Carlos, cuenta con un secador solar térmico forzado híbrido con respaldo de gas LP. El sistema forzado consiste en la circulación, mediante turbinas, de aire y agua caliente por la cámara de secado.
El sistema híbrido consiste en la utilización de energía solar y de gas natural para la elevación de la temperatura, en el interior de la cámara de secado o deshidratación. Para el proceso de control de humedad, el secador utiliza un sistema manual. Las desventajas del proceso manual de control de humedad incluyen (a) dependencia a un operador para el encendido/apagado del sistema, (b) no permite la adaptación del sistema a las condiciones ambientales circundantes al secador, (c) alto consumo energético para llegar a las condiciones de humedad requeridas para el almacenamiento y procesamiento de los productos agrícolas.
Se tuvo como objetivo la mejora del actual secador por medio de la automatización del proceso de humedad y temperatura. El sistema propuesto utiliza un PLC (Controlador Lógico Programable por sus siglas en inglés) para el control de humedad, y permite el monitoreo de las variables de humedad y temperatura, tanto interna como externa a la cámara de secado.
Los principales resultados de la investigación son una mejora en la eficiencia del secador al disminuir el tiempo en el que se alcanza los niveles óptimos de secado y la implementación de un sistema de monitoreo y visualización de las variables involucradas.

Authors: Lindberg Laura D. , Mueller Jennifer , Haas Madeleine , Jones Rachel K. 
Published: June 2022

Objectives. To investigate trends in the use and quality of telehealth for contraceptive care during the COVID-19 pandemic in the United States. Methods. The 2021 Guttmacher Survey of Reproductive Health Experiences is a national online survey of 6211 people assigned female at birth, aged 18 to 49 years, and that ever had penile‒vaginal sex. We used weighted bivariable and multivariable logistic regressions to analyze the use of telehealth for contraceptive care and the quality of this care. Results. Of the respondents, 34% received a contraceptive service in the 6 months before the survey; of this group, 17% utilized telehealth. Respondents who were uninsured at some point in the 6 months before the survey had greater odds of using telehealth for this care. Respondents had lower odds of rating the person-centeredness of their care as “excellent” if they received services via telehealth compared with in person (25% vs 39%). Conclusions. Telehealth has helped bridge gaps in contraceptive care deepened by COVID-19. More work is needed to improve the quality of care and reduce access barriers to ensure telehealth can meet its full potential as part of a spectrum of care options.

Brain Metastasis of Papillary Ovarian Adenocarcinoma
Authors: Chhabra Sonia , Dalal Niti , Singh Sunita 
Published: June 2022

Brain metastasis from epithelial ovarian cancer is a rare diagnostic entity with a reported incidence of 1- 2%. Serous epithelial ovarian cancer is usually associated with a poor prognosis and is the most common malignancy metastasizing to the brain. The median time from primary diagnosis to development of cerebral lesions is directly correlated with the initial tumour grade and stage. The median survival after diagnosis of brain metastases is 6 months. It is suggested that brain imaging studies should be included in the follow up of patients after treatment for ovarian carcinoma. We report a case of brain metastasis of ovarian adenocarcinoma 2 years post-surgery and six cycles of chemotherapy.
