A determinação dadroga foi realizada pela reação do paracetamol com ácido nitroso gerado em linha e o produto dessa reaçãofoi monitorado em 430 nm em meio alcalino. A curva analítica apresentou uma faixa de concentração deparacetamol variando entre 9,7x10 -5 a 6,2x10 -3 mol L -1 com um limite de detecção de 2,5x10 -5 mol L -1 . Osdesvios padrão relativos foram menores que 2% para soluções contendo 1,2x10 -4 e 2,8x10 -4 mol L -1 deparacetamol (n=10) e uma freqüência de amostragem de 60 determinações por hora foram obtidos.

A atividade eletrocatalítica para a oxidação de ácido fórmico e formaldeído em eletrodos bináriosde Pt e SnO 2 e ternários de Pt, RuO 2 e SnO 2 em diferentes composições, foi investigada através das técnicasde voltametria cíclica e cronoamperometria. Os materiais foram preparados por decomposição térmica deprecursores poliméricos na temperatura de 400°C. Os experimentos de voltametria cíclica mostraram queos eletrodos mistos proporcionaram uma diminuição de ~100 mV (ERH) no potencial de pico de oxidaçãodas moléculas orgânicas em relação ao eletrodo contendo somente Pt e indicaram que a composiçãoPt 0,6 Ru 0,2 Sn 0,2 O y possui maior densidade de corrente de oxidação em potenciais inferiores ao potencial depico. Os experimentos de cronoamperometria confirmam a contribuição da adição de SnO 2 e RuO 2 para oaumento da atividade catalítica em menores valores de potencial.

Alguns destes elementos são conhecidos comoinibidores do crescimento da HA, como Mg 2+ e HCO 3- . Neste trabalho, estudou-se a influência dos íonsK + e Mg 2+ na formação de apatitas sobre substratos metálicos de Ti c.p. previamente tratados com NaOH5M. Os efeitos destes íons no recobrimento obtidos, antes e após o tratamento térmico a 800oC, foramanalisados por microscopia eletrônica de varredura - MEV, espectroscopia de energia dispersiva de raios-X - EDX, difratometria de raios-X - DRX e espectroscopia no infravermelho - IV e mostraram que o efeitoinibitório do Mg 2+ na formação da HA se manifesta após o tratamento térmico. Diferentemente, ocrescimento cristalino da HA não foi afetado pela presença do íon K + . Além disso, a formação de apatitacarbonatada se deu também em soluções que não continham o íon CO 32- em sua composição.

THE ROLE OF OTT PLATFORMS IN GLOBALIZING MALAYALAM FILMS
Authors: K M Jithendran , M Aiswarya Lakshmi
Published: July 2023

After the emergence of OTT platforms, film industries based on the regional languages of India have become popular around the world. OTT platforms have given these smaller film industries a massive boost in terms of accessibility which has resulted in a much wider reach and acceptance for their films on a global scale. The Malayalam film industry or Mollywood is thought to have largely benefitted from this OTT boom. This paper aims to study the role of OTT platforms in the recent popularity and acceptance of Malayalam films, which otherwise would have been small-scale theatrical releases whose accessibility and acceptance would have been confined or limited within the respective small-scale regional audience who are familiar with the language.

Published: July 2023

India will have 1 billion smart phone users by 2026, according to a recent Deloitte report Big bets (2022). As for news consumption, a June 2022 article in Mint says that around 72% on Indians access news through smartphones, and only 35% via computers. News aggregator platforms and apps such as Google News (53%), Daily Hunt (25%), In Shorts (19%), and News Point (17%) are also gaining currency Jha (2022). Even though the use of mobile phones is increasing, a 2022 study conducted by the Reuters Institute in 46 markets says that the trust in news is falling, especially with the younger age group. Youth Avoiding News, Says Reuters Study. (2022). The report says, “These groups are critical audiences for publishers and journalists around the world, and for the sustainability of news, but are increasingly hard to reach and may require different strategies to engage them.” This study also marks the difference in the consumption pattern between social natives (18 to 24) and digital natives (25 to 34). While digital natives still stick on to Facebook, social natives have moved to other new networks. Many news organizations are struggling to remain relevant to this group of youth. Using the quantitative survey methodology, this study aims to track news consumption patterns among youth.
A 50 años del Golpe Militar, las políticas de la Memoria para las mujeres víctimas de la dictadura en Chile
Authors: Hau Espinosa Boris
Published: July 2023

El 8 de noviembre de 1974 la periodista Diana Aron fue detenida por agentes de la dictadura de Chile. Trasladada a un recinto clandestino de reclusión fue interrogada, torturada, su familia nunca más supo de ella. El caso de la periodista es una de los casos de mujeres detenidas desaparecidas o ejecutadas políticas, ex presas políticas de la dictadura que han sido parte de las políticas de Justicia Transicional. Las políticas de la memoria en Chile se han realizado desde el inicio de la democracia, en el marco de los mecanismos de Justicia Transicional. Pero estas políticas se han dado desde las exigencias de las agrupaciones de derechos humanos, no ha sido una política desde el Estado. Este trabajo reconocerá cuales han sido las políticas de la memoria que se han realizado para las mujeres victimas de la dictadura en Chile, pero a la vez dar a conocer cuales son las deudas actuales con estas políticas de la memoria. 48 años después de la detención y desaparición de Diana Aron sus familiares como amigos inauguraron una placa que recuerda su testimonio de periodista y militante de izquierda. A 50 años del Golpe Militar en Chile, las políticas de la memoria para las mujeres siguen siendo una deuda con ellas, como con sus familiares.

Published: July 2023

One of the goals of learning physics is to help students develop their critical thinking skills. Preliminary studies conducted at SMAN 1 Pacitan show that the learning process is still teacher-centered with the lecture method and providing practice questions. Such a learning process causes the development of student's critical thinking skills to be less well-stimulated. Using e-modules in physics learning is expected to be a new solution to stimulate students' critical thinking skills. This research aims to determine the impact of Problem-Based learning physics electronic module integrated with STEM on students' critical thinking skills. The research method uses a quasi-experimental technique with a one-group pretest-posttest design. Data analysis used the N-gain test to determine the increase in students' critical thinking skills and the t-test to determine the effect of problem-based learning electronic module integrated with STEM on students' critical thinking skills. The sample was selected using a purposive sampling strategy. The samples involved were 34 students of class XI MIPA Senior High School Pacitan. The test was conducted to collect data on students' critical thinking skills. Research data was collected using an essay test of critical thinking skills totaling twelve valid questions with a reliability coefficient 0.70. Before the N-gain test was carried out, the normality, homogeneity, and t-test were first carried out. In the normality test, the data is normally distributed. In the homogeneity test, the data is homogeneous. Based on the paired sample t-test, it shows that there is a significant difference between pretest and posttest critical thinking skills with a sig. (2-tailed) <0.05, which indicates that the problem-based learning electronic module integrated with STEM has a positive effect on students' critical thinking skills. By acquiring an N-Gain score of 0.76 in the high category, the PBL physics electronic module integrated with STEM on mechanical wave characteristics material can improve students' critical thinking skills.
