Microextraction-colorimetric determination of anionic surfactants in natural and waste waters
Authors: Amelin V. G. , Shogah Zen Alabden C. , Bolshakov D. S.
Published: December 2020

An eco-friendly, simple, rapid and cheap method for determining anionic surfactants in natural and waste waters by microextraction-colorimetric method has been developed. The essence of the proposed approach consisted in extraction and concentration of analytes in an acidic medium in the form of associates with organic reagents (methylene blue and acridine yellow) by dispersion liquid-liquid microextraction using a mixture of chloroform-acetonitrile as an extracting and dispersing solvent, followed by aggregation of extractant microparticles by centrifugation and subsequent measurements of color characteristics using a smartphone. The values of the basic components of the RGB colorimetric system were used as an analytical signal to calculate the final color: The selection of optimal conditions for microextraction concentration of anionic surfactants from natural waters (the nature of the extracting and dispergating solvents, the volume of the dispergating solvent) was performed for the sodium dodecyl sulfate — methylene blue system. To study the colorimetric characteristics of the prepared extracts, a smartphone «iPhone X» was used as a color-registering device equipped with a specialized software product «RGBer». To minimize the measurement error by fixing the distance to the object under study and lighting conditions, we propose an installation that increases the accuracy and sensitivity of the determination and makes the method more mobile. The total content of the most common components of detergents was determined: sodium dodecyl sulfate, sulfonol, laureth sulfate and disodium laureth-3-sulfosuccinate. The detection limits ranged within 0.01 – 0.02 and 0.05 mg/liter. The range of detectable contents for all analytes was 0.05 – 1.0 mg/liter. For the determined surfactants, the equations of the relationship between the analytical signal and the concentration were obtained. The calibration graphs are linear with coefficients of the approximation reliability ≤0.98. The correctness of the method was tested on samples of natural water using the spike test procedure. The relative standard deviation of the analysis results does not exceed 0.13. The analysis duration is 20 – 30 min.

Published: December 2020

Introduction: In 2020, a total of 2,510 new cases of breast cancer were estimated in Ceará State, 14% above the figures of 2019. In the context of the COVID-19 pandemic, postponing screening and assessing the risks and benefits of elective procedures was needed, rescheduled until after their control. Objective: We sought to identify the impact of the COVID-19 pandemic in the care of a Reference Service for Breast Cancer Diagnosis. Methods: Time series study, with analysis of the production of the consultations carried out from March to June of the current year in a service located in Fortaleza City, Ceará State. Results: There was a reduction of up to 84% in the services offered, with emphasis on mammography and ultrasound procedures, with 95 and 100%, respectively. The diagnosis of new cases and the performance of surgeries reduced by up to 60 and 56%, respectively. The months with the greatest impact were April and May, with a progressive resumption in June. Conclusion: The study evaluated a reference service of relevance in the state reality. Considering that many cases are identified during screening, postponing mammograms contributed to a delayed diagnosis. The findings are believed to pose severe consequences, considering the annual increase in the incidence of the disease, the low screening coverage, the high number of cases in advanced staging, the ascending mortality, and the low supply of diagnostic services. Diverting attention exclusively to the pandemic represents a worldwide challenge, but cancer is an important cause of morbidity and mortality, and cannot be neglected. There is concern that delaying screening, diagnosis, and treatment of breast cancer may cost more lives than COVID-19 itself. Post-pandemic requires planning to promote harm reduction resulting from the delay in the diagnosis and treatment of the repressed demand, in a disaggregated and overloaded system.

Published: December 2020

La protección de las personas con discapacidad ha atravesado diferentes facetas, desde el nulo reconocimiento de sus derechos como seres humanos hasta el reconocimiento pleno. Este reconocimiento legal no siempre se cumple en la práctica. La protección de los derechos laborales de las personas con discapacidad se incentivó con el desarrollo de los derechos humanos y desempeñan un rol fundamental porque son fuente de su independencia económica y social. El enfoque de este artículo es jurídico social, su finalidad es exploratoria, las fuentes utilizadas fueron documentales primarias y secundarias. Se trazaron tres objetivos específicos el primero encaminado a identificar las regulaciones legales laborales que existen en Paraguay protectoras de las personas con discapacidad; así como indicar la concordancia de las legislaciones laborales con los principios de los derechos humanos reconocidos en los documentos internacionales; y determinar el grado de cumplimiento práctico de lo establecido en el Código del Trabajo Paraguayo sobre el acceso al derecho al trabajo. Como conclusiones se arribó a que en Paraguay existen las legislaciones que protegen la relación laboral de las personas con discapacidad; que las leyes laborales sobre discapacidad vigentes se encuentran en concordancia con los principios y derechos humanos recogidos en los documentos internacionales; no obstante, existe una brecha entre lo que se protege en las leyes y la práctica en cuanto a la inclusión laboral de las personas con discapacidad.

The study population was 136 schools. Teacher samples were taken using a purposive sample technique based on criteria that had 10 years of teaching experience and were certified. The total sample of teachers was 160 people with the following details: elementary school: 52 teachers; Junior High School: 52 teachers; Senior High School: 52 teachers and Vocational High School: 4 teachers. In addition, 6 teachers and 3 principals became participants to be interviewed. Those interviewed did not include the number of samples. This research approach uses mixed methods. Data collection techniques used were questionnaires, interview guides and study documentation. Data analysis techniques used were descriptive statistics, ANOVA 1 lane and qualitative analysis. The results showed that there were no significant differences in the mean of academic supervision and teacher achievement motivation in the three sample groups and there were significant differences in teacher performance in the three samples. Based on the results of the qualitative analysis it was found that academic supervision was carried out without a program, the frequency and intensity of academic supervision conducted by the principal was very less. Supervision of school principals without using standard instruments, and the absence of the results of the analysis of supervision implementation Supervisors still use the bureaucratic-autocratic approach and are not participatory. Teacher achievement motivation is still very dominant triggered by welfare factors. The teacher has shown discipline, not delayed work. However, teachers have not displayed creative, innovative attitudes, independence in work, adaptability and have not reached high performance standards. The results of qualitative analysis of teacher performance variables, it was found that most teachers do not prepare their own lesson plans but copy and paste lesson plans from network sources or other colleagues; teacher copy paste Basic Competencies and indicators exactly as contained in the Minister of National Education Regulation. The teacher does not understand the preparation of HOTS (Higher Order Thinking Skill) questions and also has not been able to compile an assessment rubric. The lesson plans prepared by the teacher are only prerequisites for teaching; so it is only to fulfill formal-administrative demands and not be seen in class performance

The concept of chemical bonds is often understood in a misconception by some students which causes the understanding of misconceptions also occurs in advanced chemical concepts. The research objective is to reduce the misconception burden of chemistry teacher candidates on the basic concepts of chemistry using cognitive conflict strategies. Case study research using qualitative methods with 10 students as research subjects obtained through misconception detection tests using the three tier test method. Research data obtained using data triangulation (observation, documents, and interviews). The results obtained indicate that the cognitive conflict strategy has succeeded in changing the cognitive structure (schemata) of individual students, causing changes in the burden of high misconceptions to low and understanding misconceptions (MK) to know the concept (TK). Future studies can use cognitive conflict strategies on other chemical concepts with high or low misconceptions.

A dislexia começou a ser discutida na educação recentemente e de acordo com a Associação Brasileira de Dislexia (2019) cerca de 15% dos alunos em período de alfabetização apresentam dificuldades e prejuízos na leitura, recebendo diagnóstico. O professor é o primeiro profissional a identificar dificuldades de leitura e escrita, pois é o responsável pelo processo de alfabetização. Por isso, tem-se a necessidade de formar professores capazes de perceber as dificuldades e conseguir traçar estratégias para diminuí-las. Os sujeitos da pesquisa foram 11 acadêmicos concluintes de um curso de pedagogia a distância, que de livre e espontânea vontade responderam um questionário online através da plataforma Google Forms. A análise das informações obtidas ocorreu de modo qualitativo exploratório, fazendo um paralelo entre as respostas e os materiais já publicados. Sendo assim, buscou-se compreender a realidade de uma pequena amostra da região, no que diz respeito ao ensino EaD e o conhecimento sobre transtornos de aprendizagem. Os resultados demonstraram que as grades do curso de pedagogia abordam os transtornos de aprendizagem, permitindo aos acadêmicos o contato com o tema e a preparação para a atuação profissional. Dessa forma, tem-se a necessidade de cursos de especialização e de formação continuada sobre as dificuldades de aprendizagem, para que os professores possam obter maiores informações sobre e, consequentemente desenvolver um trabalho assertivo e que possibilite a inclusão de todos os educandos.

Ischemic stroke (IS) and type 2 diabetes mellitus are factors that aﬀect the homeostasis of low-molecularweight aminothiols (cysteine, homocysteine, glutathione etc.). It has already been shown that IS in the acute period led to a decrease a level of reduced forms of aminothiols, but it is not clear whether type 2 diabetes mellitus has a noticeable eﬀect there.

Objective: to reveal the features of homeostasis of aminothiols in patients with type 2 diabetes mellitus in acute IS.

Material and methods. The study involved 76 patients with primary middle cerebral artery IS in the first 10–24 hours after development of neurological symptoms. Group 1 included 15 patients with IS and type 2 diabetes mellitus, group 2 — 61 patients with IS and stress hyperglycemia. Their total plasma levels of cysteine, homocysteine, and glutathione, their reduced forms, and redox status were determined at admission (in the first 24 hours after IS).

Results. There was a decrease in the level of total glutathione level (1.27 vs. 1.65 μM, p = 0.021), as well as its reduced form (0.03 vs. 0.04 μM, p = 0.007) in patients with IS and type 2 diabetes mellitus. Patients with type 2 diabetes mellitus who had a low redox status of homocysteine (0.65–1.2%) and glutathione (0.7–2.0%) were also characterized by a decrease in total glutathione level (p = 0.02; p = 0.03).

Conclusion. Thus, type 2 diabetes mellitus is associated with a decrease in the level of total glutathione in acute IS. Probably, type 2 diabetes mellitus is characterized by a particular relationship between the metabolism of homocysteine, glutathione and glucose. Therefore, the search for homocysteine-dependent approaches to correct glutathione metabolism in type 2 diabetes mellitus may be of interest as an adjuvant therapy for IS.

The article represents the discussion of sarcoidosis involving the cranial nerves and meninges. It’s a rare disease diﬃcult to diagnose. This form of the disease is a progressive lesion of the nervous system, characterized by granulomatous inflammation of the membranes and /or tissue of cerebrum or spinal cord, cranial and /or peripheral nerves. Clinical signs of the nervous system disorder found in sarcoidosis, are detected only in 5–15% of patients. They are often represented by symptoms of cranial nerve damage, meningeal syndrome and epileptic seizures. X-ray computed tomography and magnetic resonance imaging of the brain do not reveal specific changes, however, they allow to exclude other structural lesions of the central nervous system and to identify neuroimaging signs, most common in the course of this disease. Diagnosis of neurosarcoidosis is possible in the presence of neurological symptoms, signs of multisystem lesions, and histological confirmation of non-caseous granulomatous inflammation in one or more organs. The article also represents a clinical observation of a patient with neurosarcoidosis, manifested by acute bilateral neuropathy of the facial nerves, unilateral neuropathy of the trigeminal nerve and meningism syndrome. The neuroimaging signs, often found in this disease, were revealed: the accumulation of contrast agent by the membranes of the brain and the tissue of cavum Meckeli. The course of the disease and diagnostic search, which made it possible to detect signs of multisystem lesion, are described. The diagnosis was confirmed by histological examination of the biopsy material of the intrathoracic lymph node. The results of neurosarcoidosis anti-inflammatory therapy are presented. The peculiarities influencing the choice of this type of treatment terms, are indicated.

The term "detonability" with respect to fuel-air mixtures (FAMs) implies the ability of a reactive mixture of a given composition to support the propagation of a stationary detonation wave in various thermodynamic and gasdynamic conditions. The detonability of FAMs, on the one hand, determines their explosion hazards during storage, transportation, and use in various sectors of the economy and, on the other hand, the possibility of their practical application in advanced energy-converting devices operating on detonative pressure gain combustion.
