A disponibilidade de informações raciais para reduzir as desigualdades em saúde no Brasil
Authors: Da Conceicao Maria Cristina Gomes , Barbosa Elisana de Lisboa , Magalhaes Juliana , De Jesus Elaine Rodriguez
Published: August 2022

Esta pesquisa analisa a cobertura e confiabilidade da autodeclaração do item raça-cor, a partir de dados do Sistema Nacional de Informação em Saúde do Brasil - DATASUS, e de questionários aplicados aos profissionais de saúde que atuam no município de Camacari, Bahia, em Brasil. Os métodos incluíram uma análise descritiva de dados administrativos de fontes nacionais e uma pesquisa aplicada em nível municipal. Os resultados mostram que as informações sobre raça-cor disponíveis no sistema nacional de saúde têm cobertura e qualidade muito baixas e que o município não possui um banco de dados local para orientar a gestão e as políticas. Os principais fatores que explicam a baixa cobertura e qualidade dos dados sobre raça-cor são a diversidade e heterogeneidade de formatos para preenchimento dos serviços de saúde, a falta de integração das informações em saúde, a resistência dos profissionais de saúde em solicitar e completar dados sobre raça-cor e a ausência de um banco de dados local. O questionário aplicado aos trabalhadores de saúde mostra que há resistências em atitudes e práticas que dificultam a melhoria da cobertura e qualidade deste item. Essas limitações para coletar informações raciais, que são fundamentais para a elaboração e planejamento de políticas sociais e ações de saúde, contribuem para a manutenção da situação de discriminação e exclusão das pessoas negras na saúde, pois camufla as peculiaridades e diversidades raciais existentes no país e faz a implementação de políticas e ações para reduzir as desigualdades raciais.

Authors: Sati S. , Pargaien N.
Published: August 2022

Wet and ravine forest areas of Nainital locality was surveyed to assess the VAM infection in some selected plant roots. Fine roots of selected plants were carefully dug out, washed and stained using root clearing methods and observed under microscope. Out of 18 plant roots only 16 were found to be associated with VA mycorrhiza. Acer pictum and Berberis species had no VAM colonization in this study. Percentage root colonization varied among the selected plant roots. In Valeriana wallichii 100% infection was observed whereas it was only 31% in Myrsine semiserrata. Vesicles were very common in VAM infected plant roots. The per cent infection was observed more in herbaceous plants followed by shrubs and woody plants. All the plant species surveyed were screened for the first time for VAM from Nainital, Kumaun Himalaya.
Spindle cell tumor of the lung: A rare case
Authors: Rawal Gautam , Yadav Sankalp , Rajamma Sujana
Published: August 2022

Spindle cell carcinoma of the lung is a rare, aggressive lung malignancy (non-small cell carcinoma) with a poor prognosis. This tumor accounts for approximately 0.4% of all lung malignancies, and due to its rarity, standard therapy is yet to be established for its management and treatment. The prevalence of this tumor is more common in males as compared to females (ratio of 4:1) and usually occurs in the sixth/seventh decade of life, more so in smokers. The authors report a case of a 79-year-old male patient who was incidentally detected and diagnosed with this rare lung carcinoma proven with a lung biopsy.

Learning behind the screen was implemented here in the Philippines since Covid-19 hit all over the world. For almost two years that people are suffering and struggling with what happened these days. Due to this pandemic, Notre Dame of Midsayap College implemented learning behind the screen. This paper is all about the effects of learning behind the screen on the learning performance of students in Microbiology and Parasitology subjects. The researchers used pre-test – post-test and interview research design. The researchers wanted to find out the learning performance through standardized pre-test and post-test which were administered in asynchronous and synchronous classes. An in-depth interview was also performed which involved both direct questioning and probing questions. Findings have revealed that the mean score of the students increased from asynchronous to synchronous class which was a teacher factor because there was communication between the teacher and students. Results also showed that the respondents had difficulties in answering the pre-test and post-test in asynchronous class, while, it is easy for them to answer the post-test during synchronous class. After a careful analysis of the responses of the respondents, the researchers concluded that the students taking Microbiology and Parasitology subjects could learn more during synchronous class or with the guidance of the subject teacher.

Authors: Konjeti Omkar , Gaikwad Nitin , RM Manjush , Saini Mukul
Published: August 2022

Background: For chronic obstructive pulmonary disease spirometry assessment of post-bronchodilator FEV1 is critical for establishing the diagnosis, staging of the disease, predicting the outcome, and planning treatment. The six-minute walk test (6MWT) is an endurance test used to evaluate functional status of patients with cardiopulmonary disorders. CAT score is a well-established tool for determining the impact of COPD on one's health.
Objective: To find out correlation between spirometric indices FEV1, FVC, FEV1/FVC, 6MWT and CAT Scores in COPD patients.
Design: Cross sectional study
Setting: Conducted from September 2019 to September 2021, for a period of 24 months in a tertiary care hospital in India

Materials and Methods: In this study, the correlation between spirometric indices FEV1, FVC, FEV1/FVC, 6MWT and CAT Scores was analyzed in 100 patients diagnosed with COPD.
Main outcome measures: 6MWT, CAT Scores and Spirometry values in COPD
Sample size: 100
Results: Most patients were males(75%) between the ages of 61-70(36%). Majority were in Stage 3 COPD(55%), followed by stage 2 of GOLD staging(25%). Most of them had CAT score range of 21–30(51%), followed by 10–20(48%) and on 6MWT majority walked a distance of 301-400 meters(43%), followed by > 400 meters(35%). The pulse rate and mean systolic blood pressure increased while mean SpO2 decreased post-6WMT with a statistically significant difference(P<.001). The correlation of 6MWT and spirometry parameters shows there was a strong positive correlation of FEV1, FVC, and FEV1/FVC with 6MWT and correlation of CAT score and spirometry parameters shows there was a strong positive correlation of FEV1, FVC, and FEV1/FVC with 6MWT with a statistically significant difference (P<.0001). There was a strong negative correlation between 6MWT and CAT score with a statistically significant difference (P<.0001)
Conclusion: The 6MWT and CAT score can be used as an effective alternative to determine the severity of COPD, according to the findings of this study especially in rural settings where access to spirometry is limited.
Limitations: Majority of the individuals in our study had mild–moderate COPD severity, emphasizing that the 6MWT's validity and efficacy should be assessed in all COPD grades.

Authors: Batista Pinto Flores Maria Jose , de Oliveira Benigna Maria
Published: August 2022

Este artigo apresenta a análise de uma experiência de institucionalização de um espaço voltado para o aprimoramento das práticas pedagógicas no ensino superior, criado em 2008, em uma universidade pública brasileira, e que assumiu como missão desenvolver uma rede de práticas educativas inovadora, colaborativa e contextualizada. Considerando o contexto da Universidade a qual nos referimos aqui, em relação à ampliação de vagas e à criação de novos cursos, analisamos essa experiência descrevendo sua trajetória de institucionalização e organização do trabalho. Estabelecemos uma reflexão com a literatura sobre pedagogia universitária buscando identificar as bases pedagógicas que têm sido sustentadas no desenvolvimento das práticas formativas. A institucionalização desse espaço como política da Universidade, que se revela na sua estrutura organizacional, tem levado a uma continuidade das ações formativas, potencializando sua missão e ampliando a compreensão do desenvolvimento do ensino de graduação para além de métricas ou técnicas. A metodologia de trabalho coletiva (realizada por estudantes, técnicos e docentes) e contextualizada, promovendo ações reflexivas e sistematizadoras das práticas pedagógicas, contribui para uma qualidade de ensino referenciada socialmente. A institucionalização de espaços desta natureza, no contexto da educação superior, é favorecedora do desenvolvimento dos docentes e dos estudantes nos espaços-tempos formativos que ocupam e reverbera na qualidade do ensino de graduação em suas especificidades. Trata-se de uma construção educativa permanente, que requer um projeto político-pedagógico assumido e explicitado em suas ações, com vistas a uma proposta formativa sustentável e crítica.

Authors: Carpentier Sebastian , Arias Pablo , Rodrigo Román
Published: August 2022

El presente estudio busca identificar y cuantificar la existencia de asimetrías en el emparejamiento (mismatch) entre las aptitudes del estudiante y la selectividad o rentabilidad del programa de educación superior al cual accede. Controlando por los antecedentes socioeconómicos y académicos de los estudiantes, se estimó la magnitud de la brecha de emparejiamiento entre grupos de interés identificados como atingentes por la literatura.  Luego, se estudiaron los potenciales determinantes de las brechas evidenciadas, como la distancia geográfica, el área de estudios, el tipo de financiamiento y la relevancia de la escuela secundaria. Los resultados muestran que los alumnos vulnerables y las mujeres sistemáticamente terminan accediendo a carreras menos selectivas y/o con menores retornos económicos, ceteris paribus. Se obtuvo que los factores más relevantes a la hora de explicar las brechas de correspondencia son el establecimiento escolar de educación secundaria, el área de estudios escogida por el estudiante y el tipo de financiamiento utilizado para costear la carrera. Los resultados resaltan la importancia de generar campañas de difusión de información para estudiantes vulnerables y de género femenino.

Este artículo presenta las conclusiones derivadas de la investigación colectiva Estrategias institucionales para la formación pedagógica, de los docentes de nivel superior, orientadas al mejoramiento de la calidad del nivel superior de educación desarrolladas por universidades de Argentina, Uruguay, Brasil y Costa Rica (NEIES-Sector Educativo del MERCOSUR). Centra su interés en la formación del docente universitario, considerando al rol del profesor universitario como primordial en tanto sujeto social posibilitador de cambios y como garante de la calidad de la formación de los futuros graduados. Basadas en esta premisa, las Universidades de Argentina, Brasil, Uruguay y Costa Rica han desarrollado acciones sistemáticas tendientes a la formación pedagógica de los profesores universitarios, tarea que se ha visto desafiada por varias cuestiones: políticas, encuadres de formación, lógicas de funcionamiento institucional, la propia biografía escolar de los docentes de este nivel, entre otros. A partir de esta problemática, la investigación se inscribe como un trabajo colectivo que pretende, a través de las investigaciones realizadas por cada grupo, contribuir a la comprensión de las particularidades que asumen estos procesos formativos, como aporte a la definición de estrategias que coadyuven al mejoramiento de la calidad de la educación en el nivel. Se llevó a cabo un diseño de generación conceptual (usualmente denominado cualitativo), utilizándose diversas estrategias de obtención de la información empírica: entrevistas, análisis de materiales documentales, grupos de discusión y reflexión.
Pensar la enseñanza en las universidades nacionales del conurbano bonaerense: Los casos de UNAJ y UNPAZ
Authors: Petrelli Lucía
Published: August 2022

Este artículo se propone conjugar análisis y reflexiones en torno de la enseñanza en la Universidad Nacional Arturo Jauretche (UNAJ) y la Universidad Nacional de José C. Paz (UNPAZ), a partir de una investigación en curso. El foco está puesto en la enseñanza como una dimensión de singular importancia en los documentos institucionales y en los testimonios de diversos referentes con gravitación en la gestión de ambas casas de estudio. La política inclusiva de sectores sociales antes excluidos de la educación superior es el punto de partida para problematizar la cuestión de la enseñanza universitaria. En estas instituciones, estas prácticas parecen distanciarse de sus formas más tradicionales y buscar otros sentidos en el marco de una concepción que define a las universidades en un diálogo con los territorios en que están emplazadas. Se trata de una enseñanza que se interroga y que se deja interpelar por los saberes que portan las y los estudiantes, desde un posicionamiento que propone otras formas del vínculo y de la construcción de conocimiento. El análisis se sustenta en un corpus de 20 entrevistas realizadas con autoridades y referentes de la vida universitaria de estas instituciones que, en todos los casos, ejercen la docencia. Asimismo, se tomó como referencia un corpus de información primaria que reunió los decretos de creación y estatutos de UNAJ y UNPAZ, datos sobre la oferta académica consignados en las páginas web, informes de evaluación internas y externas, entre otros.
Calidad de la educación superior: el desafío de la enseñanza de la investigación en la universidad

Published: August 2022

Este trabajo presenta experiencias docentes de enseñanza de la investigación social y educativa en el ámbito universitario en el marco de políticas científicas contradictorias que, con la pretensión de incentivar la formación de investigadores y su producción científica, reproduce condiciones objetivas que niegan el crecimiento genuino de la ciencia y los científicos y en este sentido de la investigación en educación. Resaltamos dos aportes innovadores y desafíos para la investigación social y educativa sobre la base de un proyecto finalizado en la Universidad de XXX.  El primero es la consideración de los modos de hacer ciencia de lo social, como diferentes maneras de pensar y concebir la práctica de la investigación social, superando la mera dicotomía cuantitativa vs cualitativa. Socializamos nuestro enfoque combinado y de triangulación, focalizando en la convergencia de los modos de hacer ciencia de lo social en educación: el modo verificativo (convencionalmente asociado con los métodos de medición), el modo de generación conceptual (convencionalmente asociado con los métodos cualitativos) y el modo de praxis participativa (convencionalmente asociado con la investigación participativa). El segundo, es la definición de nuestro proceso como una triangulación integrada, una meta de un nuevo objeto epistémico resultante de nexos entre sub proyectos. Estos aportes se visualizan especialmente en el estudio de la red de condiciones que facilitan u obstaculizan la construcción de demandas educativas de los individuos y grupos sociales por “Educación Permanente”, a lo largo de la vida.

Utilizing Social Networks as Learning Tools to Transform Education
Authors: Antonio Dejan
Published: August 2022

Collaborative learning is made possible through the use of technological communication networks, which provide information sharing places to encourage teamwork. There is a growing trend in colleges across Spain and Latin America, especially in Mexico, to use social networks, one of the most emblematic Web 2.0 tools, to teach students about the history and appeal of the Internet. There was a research done with 414 students from the 14 majors provided at the University of Guadalajara's Los Altos University Center to investigate the efficacy of social networking as a means of education. Seventy-one percent of respondents said they use them for school-related activities; 45 percent use them to study; and 42 percent use them to play, all of which highlights the growing role and influence that social networks are playing in the classroom.

Published: August 2022

Adults who are exposed to high levels of lead may develop hypertension and kidney damage. Lead exposure is dangerous for everyone, but it can have devastating effects on pregnant women and their babies. Methods such as membrane separation, ion exchange, precipitation, and biosorption are currently in use for the removal of lead pollution. Biosorption has the fewest negative aspects of these technologies due to its low operating costs, high efficiency at detoxifying low concentrations of toxicants, and small volume of disposal materials. The biosorption of the biosorption of lead (II) onto the activated carbon from Tridax procumbens is remodeled using nonlinear regression and the optimal mode was determined by a series of error function assessments. The best kinetic model for adsorption of lead (II) was Pseudo-1st order with a reasonable difference in terms of corrected Akaike Information Criterion to the next best model, which was pseudo-2nd order, and followed by the Elovich. However, the error function analyses especially the AICc was not conclusive in ranking the pseudo-1st order model as the best model due to the low (less than 5) absolute values of differences between the model. The pseudo-1st order kinetic constants obtained were qe (mg/g) of 6.181 (95% confidence interval from 5.009 to 7.352) and k1 (per min) of 0.007 (95% confidence interval from 0.004 to 0.009). Nonlinear modeling enables the determination of a 95 percent confidence interval for the uncertainty range, which can be used in model comparison and discriminant analysis.
Determination of MIC and NIC values of Allivum sativum methanolic extract against Aeromonas hydrophila
Authors: Ismail Ahmad Syazwan , Shukor Mohd Yunus , Masdor Noor Azlina
Published: August 2022

Plant extracts have been studied extensively for their ability to suppress the growth of bacteria. Because these findings were not reported on in the benchmark values, it was not possible to compare the results of this study to other investigations. Nonlinear regression analysis of the data is one of the most accurate methods of determining this value. The minimum inhibitory concentration (MIC) and non-inhibitory concentration (NIC) values of the methanolic extract of Allium sativum against the pathogen Aeromonas hydrophila were successfully determined using Lambert and Pearson's modified Gompertz model. As shown by the model's high correlation coefficient (0.995), garlic's MIC and NIC values of 28.02 mg/mL (95% Confidence Interval from 26.42 to 29.71) and 12.60 mg/mL (95% C.I., 11.88 to 13.37) suggest that it could be used as an inhibitory agent against this essential fish pathogen.
Clay Characterization and Bleaching of Crude Palm Oil Using Acid-Activated Nibo Clay
Authors: Nweke Chinenyenwa N. , Ajemba Regina O.
Published: August 2022

Acid-activated Nibo clay was applied as an adsorbent in the bleaching of crude palm oil. The collected clay sample was activated with hydrochloric acid solution after it was sun-dried and ground. The raw (NC) and activated clay (ANC) samples were characterized using XRF, SEM, and FTIR analyses. The efficiency of the bleaching process was examined by varying the adsorbent dosage, temperature and the contact time. The results of XRF, SEM, and FTIR analyses on NC and ANC showed that the clays were kaolinites with significant changes after activation. The bleaching experiment showed that increase in temperature improved the efficiency of the process. The highest bleaching efficiency of 86% was observed. The pseudo-second-order model best described the adsorption process at 100 °C when compared to correlation coefficient values of the pseudo-first-order, Intra-particle diffusion and Elovich kinetic models. The Temkin isotherm model best fitted the experimental data than the Langmuir, Freundlich and Dubinin-Radushkevich models with R2 values of >0.9 at all temperatures. The enthalpy and entropy values were evaluated as 54,943.90 J/mol and 154.6321 J/mol respectively. The enthalpy and entropy values indicated that the adsorption process was endothermic and showed an increase in randomness at the solid/liquid interface. The negative values of the Gibb’s free energy at 363 and 373 K implied that beta carotene adsorption of crude palm oil at these temperatures was spontaneous and feasible. This experimental study showed that acid activated Nibo clay can be applied as an adsorbent for the bleaching of crude palm oil at higher temperatures.
Yeast Inhibitive Assay for Anionic Heavy Metals: A review
Authors: Sadli Farah Najieha Mohd , Ammer Masyitah Husna , Shukor Mohd Yunus
Published: August 2022

One of the most common types of pollution that has a negative impact on the biotic community in aquatic habitats is heavy metal poisoning of the water. Both essential and non-essential heavy metals can be toxic to living things if their concentrations are too high for their bioavailability. Although the toxicity of heavy metals, and especially anionic metal ions, is better known than that of cationic metal ions, it is just as toxic, if not more so. The focus of this review is on the usefulness of eukaryotic organisms like yeast, Saccharomyces cerevisiae, for toxicity assessment because they can be easily maintained and developed in controlled circumstances, thereby avoiding variability issues that arise when employing more complex organisms. Recent research has shown that the majority of cellular MTT reduction occurs outside of the mitochondrial inner membrane, and that this reduction is dependent on NADH and NADPH but is resistant to respiratory chain inhibitors.
Minimum Inhibitory Concentration (MIC) and the Non-Inhibitory Concentration (NIC) Values of Salvia officinalis Methanolic Extract Against Aeromonas hydrophila
Authors: Ismail Ahmad Syazwan , Shukor Mohd Yunus , Masdor Noor Azlina
Published: August 2022

Extractions from plants have been the subject of considerable research because of their potential to inhibit the growth of bacteria. It was not possible to compare the outcomes of this study to those of previous investigations because these discoveries were not reported on in the benchmark values. The use of data-driven nonlinear regression analysis as one of the approaches to finding this value is among the approaches with the highest degree of precision. Using Lambert and Pearson's modified Gompertz model, it was possible to successfully determine the minimum inhibitory concentration (MIC) and the non-inhibitory concentration (NIC) of the methanolic extract of Salvia officinalis (sage) against the pathogen Aeromonas hydrophila. Sage's MIC and NIC values, which come in at 31.92 (95% Confidence Interval from 29.85 to 34.28) and 15.56 mg/mL (95% C.I. from14.39 to 16.71), respectively, suggest that it has the potential to be utilized as an inhibitory drug against this critical fish pathogen. This is demonstrated by the model's strong correlation coefficient, which was 0.995.

Authors: Rusnam . , Gusmanizar Neni
Published: August 2022

Due to the fact that it breaks down into acrylamide over time, polyacrylamide is one of the most important sources of acrylamide in soil. As a strategy for bioremediation, the breakdown of acrylamide by the action of microbes has seen a gradual but consistent increase in attention all over the world. In this work, a bacterium, tentatively identified as Pseudomonas sp. strain Neni-12 that had been isolated from volcanic soil showed the ability to grow on acrylamide. The acrylamide-degrading bacterium grew best in the presence of glucose with acrylamide as the sole nitrogen source. At concentrations of acrylamide ranging from 400 to 600 mg/L, the organisms saw the greatest amount of growth, where ANOVA analysis shows no difference among these temperatures; however, growth was entirely halted at concentrations of 800 mg/L and above. The optimum pH was at 7.0, and growth was maximum between 25 and 35 °C. The bacterium is also capable of growing while using acetamide as the only source of nitrogen. An acrylamide-degrading bacterium that was isolated from volcanic soil is reported for the very first time here.

Published: August 2022

While Cd production, consumption, and environmental release have all skyrocketed in recent decades, there is currently no practical way to recycle Cd compounds. This suggests that Cd compounds may be very dangerous to human health. Due to this cadmium remediation from polluted environment is urgently needed. Several viable technologies include biosorption, which has several positive aspects which include low operating expenses, very efficient detoxification of toxicants at low concentrations and low amount of disposal materials. The biosorption of the biosorption of cadmium onto the activated carbon from Tridax procumbens is remodeled using nonlinear regression and the optimal mode was determined by a series of error function assessments. Statistical analysis showed that the best kinetic model for adsorption was pseudo-1st order. All error function analyses supported the pseudo-1st order model. The pseudo-1st order kinetic constants obtained were qe (mg/g) of 5.808 (95% confidence interval from 5.043 to 6.573) and k1 (per min) of 0.009 (95% confidence interval from 0.0064 to 0.0117). Nonlinear modeling enables the determination of a 95 percent confidence interval for the uncertainty range, which can be used in model comparison and discriminant analysis.

As a result of the fact that several research do not carry out statistical diagnostics on the nonlinear model that was employed, the data could not be random. Because these systems rely on random data, this is a necessity for all parametric statistical assessment procedures. The Wald–Wolfowitz runs test was done on the modified logistics that were employed in the fitting of the growth curve of immobilized Pseudomonas putida on phenol. This test was carried out in order to determine whether or not the logistical changes had any effect on the growth curve. This test was carried out so that it could be determined whether or not the adjustments made to the logistical processes were successful. The runs test showed that there was a total of eight runs, which contradicts the expectation that there would only be seven runs due to the unpredictability of the circumstance. The assumption was based on the fact that there would only be seven runs. Since the p-value was larger than 0.05, the null hypothesis is not rejected; this suggests that there is no convincing evidence of the non-randomness of the residuals; rather, the residuals represent noise in the data. As a consequence of the findings of Grubb's test, which indicate that there is no outlier, it is not necessary to reanalyze the data because the modified logistics model used in the fitting of the growth curve of immobilized Pseudomonas putida on phenol was adequate enough. This means that the reanalysis would be unnecessary.

The biosorption of the biosorption of lead(II) onto an Antarctic sea-ice bacterial exopolysaccharide is remodeled using nonlinear regression and the optimal mode was determined by a series of error function assessments. The Sips model performed best in statistical tests including root-mean-square error (RMSE), adjusted coefficient of determination (adjR2), bias factor (BF), accuracy factor (AF), and corrected Akaike Information Criterion (AICc) which is not the same to the originally published work using a linearized form where the Langmuir and Freundlich models best represent the biosorption and the maximum biosorption capacity. The calculated Sips parameters kS (l/g) value of 0.10 (95% confidence interval from 0.08 to 0.13), a maximum monolayer adsorption capacity qmS (mg/g) value of 252.88 (95% C.I. from 222.13 to 283.64) and nS (Sips model exponent) value of 1.16 (95% C.I. from 1.34 to 1.98). This study indicates that a different isotherm model can be obtained using nonlinear regression compared to the popular linearized form that may give relatively inaccurate outcome.

Pesticides Pollutants are a major ecological issue because they kill organisms that are not their intended targets. Even in trace amounts, their diversity, toxicity, and durability are harmful to natural systems. High levels of malathion in the air, water, or food can make breathing difficult, tighten the chest, cause nausea, cramps, diarrhoea, watery eyes, impaired vision, salivation, perspiration, headaches, and even cause death. Two kinetic models—pseudo-1st- and pseudo-2nd order were used to examine the sorption isotherm of malathion onto Bacillus sp. S14, and they were fitted using non-linear regression. The pseudo-1st order model was found to be the best model by statistical analysis based on root-mean-square error (RMSE), adjusted coefficient of determination (adjR2), bias factor (BF), accuracy factor (AF), corrected AICc (Akaike Information Criterion), Bayesian information criterion (BIC), and Hannan-Quinn information criterion (HQC). A kinetic study employing the pseudo-1st order model at 150 PPM yielded an equilibrium sorption capacity qe of 4.19 mg/g (95% confidence interval from 4.137448 to 4.257148) and a pseudo-1st-order rate constant, k1 of 0.53. (95 percent confidence interval from 0.510371 to 0.559508). Further analysis is required to give evidence for the chemisorption mechanism commonly associated with this kinetic.

Bioremediation is pollution control technology that uses microorganism to clean up contaminated environment. This study was aimed at assessing the bioremediation potential of bacteria isolated from diesel-contaminated soils and screen them for the ability to remediate diesel contaminated environment using their potential to degrade diesel as carbon and energy source. Diesel-contaminated soil samples were collected using standard method. Bacteria were isolated, characterized and identified using standard microbiological procedures. The identified bacteria species were subsequently screened for diesel biodegradation potential in Bushnell Haas Media (BHM). Optimum conditions (pH, temperature, and diesel concentrations) for biodegradation were determined. The results showed that Bacillus subtilis and Bacillus megaterium were the most potent species identified. Bacillus subtilis and Bacillus megaterium were observed to utilize diesel as the sole carbon source in which they degrade 79% and 80% diesel during the 25 days incubation study respectively. Optimum diesel biodegradation for Bacillus subtilis and Bacillus megaterium were temperatures of between 30 and 35 C, pH between 6 and 7, diesel concentrations between 3% and 2%. The findings of this study demonstrated the species' ability to digest fuel, suggesting their potential utility in the broad-scale bioremediation of diesel-contaminated soils.

Authors: Findlay Joseph , Piche-Larocque Caleb , Faroque Akhter
Published: August 2022

Against the historical backdrop of costly advances in medical technology driving up aggregate health care cost increases across high-income countries, this paper raises a fundamental question: can the high costs of medical innovations be justified when evaluated against the public health benefits of the innovations? In this paper, we offer an answer to this question using a two-step empirical methodology applied to pooled data across Canadian provinces over the period 1980-2014. We estimate the health care cost increases due to medical innovations using a residual-based approach and evaluate the ability of the residual-based cost estimates of medical innovations to explain log-level and the growth rates of four separate public health indicators, including life expectancy at birth, life expectancy at age 65, preventable deaths and infant mortality. We verify the sensitivity of our findings across three separate estimation methods: Pooled-least squares, bias-corrected pooled-GLS and pooled-system estimation methods.
