Hemoglobinopathies are a major health problem worldwide. These disorders are characterized by a variable clinical and hematological situation related to a phenotypic heterogeneity. Moreover, in order to have an exact correlation between the biochemical picture and the genetic defect associated with it, it is useful and often indispensable the molecular study of alpha and beta globin genes. The present case report concerns a pregnant woman of Moroccan ethnicity who came to our observation to undergo combined first-trimester testing useful for screening of major chromosomal aneuploidies. Study of hemoglobins A, A2, and F by High performance liquid chromatography (HPLC) revealed the presence of a proportion of abnormal hemoglobin associated with hemoglobin S. Molecular investigation of globin genes excluded that the biochemical variant in question was related to hemoglobin S. In fact, molecular investigation of beta globin genes, found that the observed variant was due to the presence of a genetic defect leading to hemoglobin O Arab synthesis. Evidence suggests that molecular analysis of globin genes provides the most effective and correct way to correlate the detected biochemical picture with its associated genetic defect. The only biochemical study in the presented case determines an incorrect clinical evaluation with consequent inaccurate prognosis. The mutation detected in this work can be identified using a simple and inexpensive kit. This would generate, in economic terms, significant savings associated with a correct diagnosis

Introduction: Infectious skin disease with clinical manifestations of benign papules, which is often caused as a sexually transmitted disease in adults, caused by the molluscum contagiosum virus, a member of the poxvirus. Manifestations of the disease are asymptomatic, discrete, smooth papules. It usually develops from peduncled lesions up to 5 mm in diameter. The incubation period for Molluscum contagiosum is from one to several weeks to 6 months. Molluscum contagiosum is a viral infection that can heal spontaneously. There are 4 main subtypes of Molluscum Contagiosum 4 Virus (MCV), namely MCV I, MCV II, MCV III and MCV IV. These four subtypes cause similar clinical symptoms in the form of papular miliary lesions that are limited to the skin and mucous membranes. MCV I is known to have a greater prevalence than the other three subtypes. About 96.6% of molluscum contagiosum infections are caused by MCV I. However, in patients with decreased immune status, the prevalence of MCV II is 60%.
Avaliação científica e subjetividade: o “artigo-comprimido” como síntese de uma produção científica alienante
Authors: Magnin Luana Silvy de Lorenzi Tezza , Faria José Henrique de , Petean Gustavo Henrique
Published: January 2022

Diante das mudanças dos últimos anos no campo da avaliação científica, o objetivo deste artigo é caracterizar os efeitos da relação das atuais políticas de avaliação científica da CAPES e a subjetividade dos pesquisadores públicos em Administração. O estudo qualitativo foi realizado com 13 pesquisadores com alto índice de publicação e os enunciados foram analisados a partir da filosofia da linguagem de Bakhtin. Os resultados apontam para três eixos principais: (i) perda da dimensão coletiva da universidade como instância política de reflexão e decisão; (ii) corrida cega para um fim que não é problematizado; (iii) invisibilidade da intensificação do trabalho e negação de sua relação com os processos de saúde/doença. Esses eixos, em conjunto, expressam o grau de alienação a que chegou o trabalho científico, no qual a publicação da pesquisa segundo um padrão específico torna-se mais meritória que sua própria concepção e desenvolvimento. Constata-se uma ruptura, um desencontro, entre significado e sentido, que passam a ser ocupados por vozes monológicas –  padronizantes – e que aniquilam a pluralidade que constitui, de fato, o fazer científico. Conclui-se que o desejo e o empenho dos pesquisadores em atender aos critérios de avaliação direcionam a produção acadêmica. Nota-se também a redução do exercício da autonomia e da dimensão política e social de reflexão na Academia.

Authors: Achonu Chinmeri U , Amira Christiana O , Abiola Abdulhakeem O
Published: January 2022

Introduction: Hypertension is defined as a sustained elevation in the blood pressure of an individual above levels considered normal for the individual’s age, sex, race, and body size. Awareness of hypertensive status among traders in Enugu was 29.4% as of 2017. This study focused on the level of awareness, treatment and control of hypertension among traders in Lagos because of the increasing morbidity and mortality from hypertension in Lagos.

Materials and Methods: This was a descriptive cross-sectional study conducted among a total of 391 traders selected from the Tejuosho market, Iponri market and Orile Iganmu market. Data were collected using an interviewer-administered questionnaire and blood pressure was read using a digital sphygmomanometer as well as anthropometric measurements. Data obtained was analyzed using Epi-info 7.2 software. Analysis was done at a 95% confidence interval with a P-value of < 0.05 considered statistically significant. Associations between categorical variables were assessed using the chi-square test.

Results: It was found that only 46.6% of the traders were aware of their hypertensive status with 62.5% currently on treatment and less than half (43.3%) being controlled for hypertension.

Conclusions: This study showed that awareness of hypertensive status among the traders was low and the majority of the hypertensive traders were poorly controlled despite treatment greater than 6months.

Recommendations: Traders to be educated about their health regularly, undergo frequent blood pressure screening and for Lagos state ministry of health to stipulate and enforce guidelines for hypertensive patients to get specialist care by regulating the activities of private hospitals in the management of hypertension.

Authors: Gilmanshina Suriya , Sagitova Rimma , Khalikova Fidaliya , Gilmanshin Iskander
Published: January 2022

In this article the system of project activities on chemistry and energy saving disciplines which is developed and implemented by the authors for developing learners' interest in natural sciences is presented.
The implemented system of projects to develop learners' interest in natural sciences integrates three interrelated blocks of project activities: project activities of learners under the guidance of teachers, project activities of students – pre-service teachers with aim to popularize science in online mode and the activities of university teachers on innovative career guidance projects for school students. The main feature of project activity of learners based on the personality-oriented approach is revealed, which is connected with its complication from mini-projects to design-research assignments. It was revealed that the conditions of elective courses are especially favorable for this purpose. The elective course, according to the Russian educational standard, is a compulsory course which is selected by the student's choice, one of the organizational forms of chemistry teaching. Elective courses of preprofile preparation target graduates of secondary school to perceived choice of the future major of education in high school. There are the following elective courses: subject-oriented, interdisciplinary (integrated) and applied feature. The subject-oriented elective courses are aimed to develop the cognitive interest in the subjects of the chosen profile, to expand and to deep the knowledge of students in the profile discipline. Interdisciplinary elective courses are designed to integrate knowledge into related disciplines, as a necessary condition for successful education in the high school. Elective courses of applied feature show the connection of the certain subject to life.
The specifics of students' project activity on the development of school students' interest in natural sciences, related to the interactive popularization of science (chemical shows) are revealed. The main feature of the project activity of university teachers in the development of school students' interest in natural sciences is connected with the implementation of such innovative projects as the Small Chemical Institute and the project-oriented teaching of school students at the departments of the university.
The effectiveness of the implemented system of project activities to develop the interest of learners in the natural sciences on the example of chemistry is experimentally proved.

WHEN VILNIUS UNIVERSITY WAS CLOSED: THE GEOLOGICAL COLLECTIONS OF VILNIUS UNIVERSITY IN THE VILNIUS MUSEUM OF ANTIQUITIES
Authors: Rudnickaitė Eugenija
Published: January 2022

In Vilnius University Geology museum gathered, scientifically unique, material was never hidden from society. These resources are perfectly fit for: education, geoscientific knowledge propagation, informal natural science education (Rudnickaitė, 2003; 2007; 2012; ect.).
When writing about the geology and mineralogy collections of Vilnius University, the Vilnius Museum of Antiquities and the Department of Natural History of the Museum of Antiquities under the Vilnius Public Library are always necessarily, though often fragmentarily, mentioned. This is an attempt to identify the part of the Geological collections that was transferred to the Vilnius Museum of Antiquities compiled by associate member of the Vilnius Temporary Archaeological Commission, teacher of natural sciences of the Vilnius 1st boys’ gymnasium, Kajetan Tamulewicz (1828-1870), a catalogue of the Department of Natural History of the Museum of Antiquities under the Vilnius Public Library from 1905, a catalogue of mineralogy compiled by a professor of the Vilnius Medicine and Surgery Academy and the author of several textbooks in mineralogy, Ignacy Jakowicki (1794-1847), from 1836 and other known sources. The scientific quality of the collections, their structure and more outstanding exibits are discussed. A small part of the collections, which were taken away in the 1840s and brought back from the Ilya Mechnikov State University in Odessa to the Geology and Mineralogy Museum of Vilnius University by professor Juozas Paškevičius and Eugenija Rudnickaitė on 23 May 1986, has also been used for the research.
The author attempts to identify the exibits of the geological collections of Vilnius University that remained in Vilnius and were subsequently transferred to the Vilnius Museum of Antiquities (later, the Museum of Antiquities under the Vilnius Public Library) by comparing the list of exibits returned from the University of Odesa with the data in Jakowicki’s catalogue.
It was mentioned in the minutes of the annual session of the Vilnius Temporary Archaeological Commission of 11 January 1858 that the systematically arranged collections became an excellent teaching aid for young people aspiring to education, and during the last year the museum received 11,800 visitors.
The author can assert that the Vilnius Museum of Antiquities made a great contribution to society’s education and training of school children, the development of the science of geology and mineralogy in the period when there was no institution of higher education in Lithuania. E.Tyszkiewich had an exclusive role in this activity - he continued geological research even after the closure of the Vilnius Museum of Antiquities.

Authors: GULOTTA Florencia A. , DIAZ VERGARA Ladislao , MONTENEGRO Mariana , FERREYRA Nancy F. , PAZ ZANINI Verónica I.
Published: January 2022

Multilayer films made of glucose-functionalized chitosan (G-Chit) and glucose oxidase (GOx) were built by layer-by-layer self-assembly technique onto carbon paste electrodes (CPE). The obtained bioelectrodes were characterized by cyclic voltammetry and chronoamperometry. Results indicated that catalytic response increases with the number of bilayers G-Chit/GOx and the enzyme concentration obtaining the best responses for 3 bilayers and 2 mg ml-1, respectively. The effect of pH on the bioelectrode response was also investigated, it was found that the optimal working value is 7.0. Under optimized experimental conditions, the biosensor exhibits a sensitivity of (0.81 ± 0.03) µA mM-1 in a glucose concentration range 0.18 to 1.75 mM. The analytical response of the biosensor was tested in milk samples with negligible matrix effects. Results show that G-Chti appears promising for the immobilization of enzymes.

Published: January 2022

La hierba mate (Ilex paraguariensis) es un producto común en los países de América del Sur. El consumo en esta región se realiza en forma de infusión fría o caliente. El objetivo de este trabajo fue realizar la cuantificación de hongos filamentosos y levaduras de las hierbas mate comercializadas en Cuiabá, capital del estado de Mato Grosso, Brasil. Fueron investigadas 16 muestras de hierbas mate disponibles en el comercio, separadas en dos grupos: hierbas puras y hierbas compuestas. Alícuotas de 25g fueron colocadas en viales que contenían 225 ml de peptona al 1%. Posteriormente se transfirieron 100µl a placas de Petri que contenían agar Sabouraud con 0,4 mg/L de cloranfenicol. Las placas se incubaron a 25° C durante 7 días. El 93,75% de las muestras mostraron crecimiento de hongos filamentosos y/o levaduras en contajes de 2x102 hasta 1,1x103. Las colonias de hongos filamentosos fueron sugestivas de los géneros Aspergillus y Penicillium. Las muestras resultaron aptas para el consumo según los parámetros de la OMS, sin embargo, en la actual normativa brasileña no existen parámetros para definir las cargas de hongos filamentosos y levaduras aceptables en este tipo de preparados. La normativa sobre seguridad microbiológica de los alimentos vigente en Brasil, no contiene parámetros para definir la carga aceptable de hongos filamentosos y levaduras en diferentes tipos de infusiones, revelando una brecha de riesgos para la salud humana, ya que no es posible certificar si un producto es seguro para el consumidor.
Sensing Method for Two-Target Detection in Time-Constrained Vector Poisson Channel
Authors: Fahad Muhammad , R. Fuhrmann Daniel
Published: January 2022

It is an experimental design problem in which there are two Poisson sources with two possible and known rates, and one counter. Through a switch, the counter can observe the sources individually or the counts can be combined so that the counter observes the sum of the two. The sensor scheduling problem is to determine an optimal proportion of the available time to be allocated toward individual and joint sensing, under a total time constraint. Two different metrics are used for optimization: mutual information between the sources and the observed counts, and probability of detection for the associated source detection problem. Our results, which are primarily computational, indicate similar but not identical results under the two cost functions.
A Comparative Study of Machine Learning Algorithms for EEG Signal Classification
Authors: Hashmi Anam , Alam Khan Bilal , Farooq Omar
Published: January 2022

In this paper, different machine learning algorithms such as Linear Discriminant Analysis, Support vector machine (SVM), Multi-layer perceptron, Random forest, K-nearest neighbour, and Autoencoder with SVM have been compared. This comparison was conducted to seek a robust method that would produce good classification accuracy. To this end, a robust method of classifying raw Electroencephalography (EEG) signals associated with imagined movement of the right hand and relaxation state, namely Autoencoder with SVM has been proposed. The EEG dataset used in this research was created by the University of Tubingen, Germany. The best classification accuracy achieved was 70.4% with SVM through feature engineering. However, our prosed method of autoencoder in combination with SVM produced a similar accuracy of 65% without using any feature engineering technique. This research shows that this system of classification of motor movements can be used in a Brain-Computer Interface system (BCI) to mentally control a robotic device or an exoskeleton.
ASSESSMENT OF OVERGROWTH OF AGRICULTURAL LAND WITH FOREST VEGETATION IN THE BEREZOVSKY CITY DISTRICT OF THE SVERDLOVSK REGION
Authors: Бартыш А.А. , Никитин Р.Р.
Published: January 2022

В рамках данной работы оценивались степень и масштабы зарастания сельхозугодий Берёзовского городского округа Свердловской области. Оценка велась по материалам открытой базы данных Росреестра с кадастровыми номерами и границами участков, а также по соответствующим местности космоснимкам. Учитывались только участки, предназначенные для пахоты, сенокошения и выпаса скота, бывшие сельские леса исключались. Так как юго-западная часть Берёзовского городского округа находится практически в черте г. Екатеринбурга, там ведётся активная застройка, поэтому участки отбирались площадью не менее 5000 м2 (0,5 га), для того чтобы отсечь земли, которые могли быть переведены под застройку. Анализ пространственного расположения показал, что исследуемые участки находятся в южной и центральной части Берёзовского городского округа. Основной конгломерат находится в южной части округа, на юго-востоке от г. Берёзовского, с юга от посёлка Шиловка и до посёлка Становая. Еще часть участков находится восточнее на юге от посёлка Сарапулка. В центральной части округа возле посёлка Монетный участки сильно разбросаны. Общая площадь выявленных сельскохозяйственных угодий 3791 га, из них 49 % не заросли древесной растительностью, 12 % – зарастающие сельхозугодья. Результаты оценки показали, что зарастание происходит неравномерно. В большинстве случаев покрытой лесом оказывается небольшая часть земельного участка. На данный момент 51 % сельхозземель Берёзовского городского округа заброшены и в той или иной степени заросли древесной растительностью, в том числе 39 % покрыто лесом. Таким образом, в той или иной степени используется только половина сельхозугодий.
Aspectos das habilidades da compreensão leitora do aluno da EJA em regime de privação de liberdade.
Authors: Mota Elisângela Santiago , Machado Cláudia Aparecida Ferreira
Published: January 2022

Sabe-se que é necessário ações efetivas para garantir a preparação do indivíduo em privação de liberdade para conviver novamente no meio social. Há várias práticas que podem ser desenvolvidas para ressocialização desse apenado. Uma delas é a leitura. Isso porque não se pode negligenciar a importância da leitura para garantir direitos, ampliar a capacidade crítica e libertação do que era para o outro que se transforma, conforme Freire (1989) afirma. Com o intuito de investigar em que nível a habilidade de leitura desses apenados se encontram, realizou-se uma pesquisa qualitativa para verificação das competências leitoras já consolidadas e não consolidadas desses indivíduos. Os contemplados foram os alunos dos 8º e 9º anos da Educação de Jovens e Adultos (EJA) em situação de privação de liberdade, da Escola Estadual Padre Henrique Munáiz Puig, localizada no Presídio Regional de Montes Claros. O objetivo desse trabalho foi fazer um levantamento para identificar se esse aluno-leitor em privação de liberdade está usufruindo significativamente daquilo que se lê. A coleta dos dados foi realizada por, primeiramente, um questionário com sete perguntas pessoais, com o intuito de traçar parcialmente o perfil do pesquisado e, em seguida, realizou-se uma avaliação diagnóstica contemplando gêneros textuais variados, cujas questões basearam-se nos descritores da Matriz de Referência de Língua Portuguesa do SAEB, referente ao 9º ano do Ensino Fundamental. Este estudo foi fundamento em Freire (1996), Freire (1987), Solé (1998), Oliveira, Lúcio e Miguel (2016, Julião e Paiva (2014), Sistema de Avaliação da Educação Básica (SAEB) e Leis de Diretrizes e Bases da Educação Nacional (LDBEN).
Conotação formativa da linguagem em Ludwig Wittgenstein.
Authors: Oliveira José de
Published: January 2022

Analisar a conotação formativa da linguagem quando travada pelo conhecimento metafísico é a meta proposta da investigação, tendo como referência a filosofia de Ludwig Wittgenstein (1889-1951). Bem sabemos, em relação ao conhecimento, desde a Grécia antiga ou medieval e, ainda hoje, grande parte dos filósofos insistem em construir um sistema de proposições universalmente válidas. Para tanto, é necessário, antes de tudo, fazer uma exposição histórica das questões epistemológicas que levaram esse filósofo a entender que a linguagem é um caminho seguro e pode oferecer uma solidez não apenas à linguagem, mas também ao trabalho da filosofia. E assim, em seguida, debruçar à demonstração das razões que nos levam a entender que as pretensões filosóficas nem sempre são legítimas como assim pensavam os tradicionais da filosofia. Digamos de passagem, nossa reflexão é trivial na esfera filosófica. Alavancado metodologicamente por uma trilha analítica, o trabalho se divide em dois momentos, o primeiro, aborda questões sobre o conhecimento metafísico e a aparente pretensão finalística de um suposto conhecimento metafísico, num segundo momento, trata-se de investigar a linguagem na dimensão dos jogos de linguagem. As fontes principais de investigação são: Tractatus Logico-Philosophicus (1968) e, Investigações Lógicas (1999).
Território e cor da violência, racismo no Brasil e seus desdobramentos na escola: contribuição do pensamento de Paulo Freire sobre a educação emancipadora das questões étnico-raciais
Authors: Silva Mercelo , Sena Viviane de Andrade Soares
Published: January 2022

Neste artigo procuramos discutir a violência escolar como eixo estrutural da exclusão das populações periféricas, em especial aquelas em que o índice de concentração da população negra é maior. Assim, tratamos da persistência do racismo no Brasil como um fator que contribui para que o problema violência seja recorrente na nossa sociedade, principalmente na escola. Para isso, primeiramente, apresentamos um estudo teórico-histórico de modo a contextualizar a relação existente entre as desigualdades raciais e as desigualdades escolares. Por conseguinte, abordamos sobre a discussão freireana como instrumento de luta contra as desigualdades. Neste trabalho reforçamos e ampliamos a discussão sobre essa problemática, tecendo, dentre outras, considerações acerca do papel da escola e da atuação docente. Portanto, nosso objeto de estudo é a violência decorrente do racismo e nosso objetivo é compreender os mecanismos de exclusão de crianças e jovens privados de direitos elementares previstos em uma “democracia”. A escola é para “todos”, mas a educação é ainda para poucos. Concluímos que o negacionismo quanto à realidade do negro representa um ponto primordial para o entendimento da violência que circunda a escola e s sua superação se coloca a partir de um ideal de emancipação.

O presente trabalho objetiva, sob a perspectiva dos direitos humanos, destacar a relevante inclusão social que pode ser alcançada com a utilização de meios eficientes de acesso à justiça. Superar problemas ligados à comunicação é fundamental para a construção de respostas conjuntas pelas partes, sendo a mediação um mecanismo eficiente para facilitar o diálogo entre pessoas em conflito. A atuação do mediador favorece falas simplificadas e, com o uso da técnica de escuta ativa, contribui para o enfrentamento de problemas ligados à tradicional linguagem jurídica. A utilização de uma linguagem acessível a todos é característica da mediação e colabora para superar incompreensões técnicas, possibilitando a participação ativa de todos na resolução de disputas.
Resenha do livro - Pedagogia do Oprimido
Authors: Amorim João Bosco Alves de , Nunes Celia Maria
Published: January 2022

O livro Pedagogia do Oprimido foi editado pela Paz e Terra, do Rio de Janeiro, aqui no Brasil, somente em 1976, pela censura imposta pelos militares. Sua primeira publicação foi em 1968, grande parte dele foi escrito em Santiago, no Chile, nos 05 anos que Paulo freire ali viveu, exilado, sendo finalizado e publicado nos Estados Unidos. Trata-se da obra mais conhecida, senão a mais importante, de autoria do educador brasileiro Paulo Freire (1921-1997). Esta obra é considerada um dos maiores clássicos da Ciências Humanas e Sociais atuais, notadamente no campo da Educação ou da Pedagogia. Costuma-se reconhecer que a obra que buscamos resenhar é a terceira publicação de maior número de citações, no campo da Ciências Humanas e Sociais, no mundo todo, ultrapassando índices de textos clássicos de autores universalmente consagrados como Sigmund Freud (1856-1939) e Karl Marx (1818-1883). Paulo Freire tornou-se o mais importante educador contemporâneo, sem sombra de dúvidas, e provavelmente alcançou a estatura de ser considerado um dos grandes intelectuais da Ciências Humanas e Sociais contemporâneas, atuando no campo da Educação e da Cultura.
Metodologia da pesquisa em gestão escolar e do trabalho da diretora: limites e possibilidades
Authors: Silva Marcus Quintanilha da , Cruzetta Danieli D'Aguiar
Published: January 2022

O objetivo deste trabalho foi de compreender de que forma as abordagens metodológicas na pesquisa em gestão escolar podem contribuir para a análise do trabalho da diretora escolar em uma perspectiva democrática. Pautado em uma revisão de literatura que indicasse elementos essenciais para a análise da efetividade da gestão democrática (GD) no âmbito do trabalho da diretora escolar, as abordagens quantitativa, qualitativa e uma forma híbrida de relação entre as duas, na qual denominou-se quanti-quali, compuseram um diálogo com experiências de pesquisas anteriores, indicando limites e possibilidades de resultados de pesquisa a partir da metodologia adotada. Os resultados indicaram que cada abordagem tem possibilidades de abstrair resultados que contribuem para o campo, mas que se limitam em determinados aspectos, sendo essencial que a escolha metodológica dialogue com a expectativa do pesquisador/a em torno de seu objeto.

On the Field Performance of PV Water Pumping System in Libya
Authors: Sbeta M. , Sasi S.
Published: January 2022

This paper presents the measured performance of an experimental PV water pumping system of 1200W installed in the north-east of Libya. Both the monthly and hourly measured data of the system performance are presented and analyzed, and the over-all system efficiency has been calculated as monthly and daily averages. The monthly average output of the system has been estimated and compared with measured data. The economic analysis of the system has been carried out and the speciﬁc water discharge cost {SDC} has been determined. The obtained SDC was very competitive with the published SDC of the PV water pumping projects in some countries. The obtained results have demonstrated the technical and economic feasibility of using the PV systems for water pumping especially in the remote areas of high potential of solar insulation
Projected Avoided Costs of Conventional Power Plants in Libya Using Wind Energy
Authors: I. Abuzend W. , El-Osta W. , A. Ekhlat M. , Borass E.
Published: January 2022

This paper investigates the costs that can be avoided by using wind energy in the central coastal area of Libya. The investigation of the capacity credit was performed in a previous work. The analysis included Fuel saving, capacity saving and emission reduction (NO, SO2 and CO2) to the atmosphere. The avoided costs were translated into equivalent energy costs of wind energy systems. The evaluation was conducted using the reliability (LOLP) analysis and the contribution of wind system during peak demand to the utility total electricity generation system. The calculations were carried out using WASP (Wien Automatic System Planning Package) for the proposed period of 2009-2019 where wind power installation would increase from 100 MW in 2009 to 500 MW in 2019.
The results showed that the avoided costs of wind energy will increase from 2.4 c/kWh in 2009 to 8.6 c/kWh in 2019. The mean value of the avoided costs of wend energy over the 10-year period is 6 c/kWh, which would make wind power economically competitive with conventional power plants in Libya. Further investigations of detailed external costs of all energy systems in the national energy mix, as well as the feed-in tariff, are recommended and should be introduced to the national energy sectors in order to promote the implementation of wind energy and other renewable energy technologies.

An Integrated System of Gasoline Reformer and Thee Way Converter for On-board hydrogen Production
Authors: Ashur Mukhtar
Published: January 2022

On-board exhaust gas assisted gasoline reforming has been investigated using a compact prototype system consisting of a fuel reformer integrated with a three-way catalytic converter (TWC) connected to a V6 engine running at homogeneous charge compression ignition (HCCI) mode, the integrated fuel reformer, and TWC were designed and constructed to supply reformed exhaust gas recirculation (REGR) stream to the gasoline-fuelled HCCI V6 engine as supplement fuel to improve engine performance and reduce NOx emissions.To find the optimum operating conditions of the engine-reformer system (in terms of hydrogen production and thermal efficiency), the effect of oxygen to carbon ratio (O2/C) in the reactor input mixture, and the different engine operating conditions were investigated. The reactor outlet temperature appears to be strongly correlated to the production of hydrogen. Concentrations up to 12.8 % of hydrogen in the reformer products were achieved from commercial unleaded gasoline. Uncompleted reforming of gasoline was assumed from significant quantities of hydrocarbons in the product measured by Non-Dispersive Infrared (NDIR).

Ülkemizde taşınmaz kültür varlıkları olan tarihi yapıların ve alanların tescillenme işlemleri çok doğru sonuçlar elde edilemediği yıllardır tartışılmalı bir konu olmuştur. Bu sorunların giderilmesi için dünyada uygulanan tescilleme teknikleri incelenmiş ve birçok ülkenin tescil için analitik yöntemler geliştirdiği görülmüştür. Almanya’nın Hessen eyaletinin ve Kanada’nın uyguladığı puanlama sistemine dayalı tescilleme sistemleri ele alınmıştır. Bu değerlendirme sistemlerinin süreçleri bu çalışma kapsamında oluşturulan model için yol haritası olarak kullanılmıştır. Bu kapsamda Kanada ve Almanya’nın “analitik tescil” sistemlerinin kriterleri incelenmiş ve ülkemizdeki tescil değerlendirmelerinde önem verilen uygun kriterler de eklenerek bir “kriter listesi” oluşturulmuştur. Bu kriterlerin, “Analitik Hiyerarşi Süreci” (AHS) yöntemi ile önem dereceleri belirlenmiştir. Bir analitik hiyerarşi yöntemi uygulama programı olan Expert Choice ile belirlenen önem derecelerine göre 100 puanlık değerlendirme ölçütüne göre kriterler arası puan dağılımı yapılarak modelin puanlama sistemi oluşturulmuştur. Bu model ile yapılacak değerlendirmelerin nesnel verilere dayanması ve bu verilerin matematiksel bir yöneteme çevirmesi kişisel değerlendirmelerde yaşanan sorunların önüne geçilmesi planlanmıştır. Türkiye’deki taşınmaz kültür varlıklarının tarihi değerlerinin belirlenmesinin nesnel bir sistem ile değerlendirilmesinin yanı sıra günümüz teknolojik gelişmelerine uygun şekilde veri aktarımını kolaylaştıracak bir veri sistemi de oluşturulmuş olacaktır.
‘Biguine d’amour’ : l’intermélodicité ‘récituelle’ dans La Mulâtresse Solitude
Authors: Eloidin Esther
Published: January 2022

Dans La Mulâtresse Solitude, André Schwarz-Bart nous livre un récit à la jonction de plusieurs textes de chansons dont il fait à la fois l’écho, la transmission, la réinterprétation, l’accentuation, la reprise et la transformation. Appliquer à ce récit la transposition du principe de l’approche intertextuelle au domaine musical, ainsi que le suggère Florence Mouchet dans son étude sur les chansons médiévales, paraît comme une évidence. Il sera donc ici question d’intermélodicité dont le récit secondaire peut se lire comme un long ‘récituel’ dédié à la mémoire des esclaves et plus particulièrement à celle de la Mulâtresse Solitude. Les travaux réalisés par Kathleen Gyssels, Élie Duprey ou encore Francine Kaufmann permettent d’étendre la réflexion dans ce sens. C’est pourquoi cette analyse tente d’apporter un autre éclairage sur le caractère profondément énigmatique de la musique schwarz-bartienne.

Abstract. Polycyclic aromatic hydrocarbons (PAHs), their alkylated (RPAHs), nitrated (NPAHs) and oxygenated (OPAHs) derivatives are air pollutants. Many of these substances are long-lived, can undergo long-range atmospheric transport and adversely affect human health upon exposure. However, the occurrence and fate of these air pollutants has hardly been studied in the marine atmosphere. In this study, we report the atmospheric concentrations over the Mediterranean Sea, the Red Sea, the Arabian Sea, the Gulf of Oman and the Arabian Gulf, determined during the AQABA (Air Quality and Climate Change in the Arabian Basin) project, a comprehensive ship-borne campaign in summer 2017. The average concentrations of ∑27PAHs, ∑19RPAHs, ∑11OPAHs and ∑17NPAHs, in the gas and particulate phase, were 2.85 ± 3.35 ng m−3, 0.83 ± 0.87 ng m−3, 0.24 ± 0.25 ng m−3 and 4.34 ± 7.37 pg m−3, respectively. The Arabian Sea region was the cleanest for all substance classes, with concentrations among the lowest ever reported. Over the Mediterranean Sea, we found the highest average burden of ∑26PAHs and ∑11OPAHs, while the ∑17NPAHs were most abundant over the Arabian Gulf (known also as Persian Gulf). 1,4 Naphthoquinone (1,4-O2NAP) followed by 9-fluorenone and 9,10-anthraquinone were the most abundant studied OPAHs in most samples. The NPAH composition pattern varied significantly across the regions, with 2 nitronaphthalene (2-NNAP) being the most abundant NPAH. According to source apportionment investigations, the main sources of PAH derivatives in the region were ship exhaust emissions, residual oil combustion and continental pollution. All OPAHs and NPAHs except 2-NFLT, which were frequently detected during the campaign, showed elevated concentrations in fresh shipping emissions. In contrast, 2-nitrofluoranthene (2-NFLT) and 2-nitropyrene (2-NPYR) were highly abundant in aged shipping emissions due to secondary formation. Apart from 2-NFLT and 2-NPYR, also benz(a)anthracene-7,12-dione and 1,4-O2NAP had significant photochemical sources. Another finding was that the highest concentrations of PAHs, OPAHs and NPAHs were found in the sub-micrometre fraction of particulate matter (PM1).
Effect of rainfall-induced diabatic heating over southern China on the formation of wintertime haze on the North China Plain

Abstract. During the winters (December–February) between 1985 and
2015, the North China Plain (NCP, 30–40.5∘ N,
112–121.5∘ E) suffered many periods of heavy haze, and these
episodes were contemporaneous with extreme rainfall over southern China;
i.e., south rainfall–north haze events. The formation of such haze events
depends on meteorological conditions which are related to the atmospheric
circulation associated with rainfall over southern China, but the underlying
physical mechanism remains unclear. This study uses observations and model
simulations to demonstrate that haze over the NCP is modulated by anomalous
anticyclonic circulation caused by the two Rossby wave trains, in
conjunction with the north–south circulation system, which ascends over
southern China, moves north into northern China near 200–250 hPa, and then
descends in the study area. Moreover, in response to rainfall heating,
southern China is an obvious Rossby wave source, supporting waves along the
subtropical westerly jet waveguide and finally strengthening anticyclonic
circulation over the NCP. Composite analysis indicates that these changes
lead to a stronger descending motion, higher relative humidity, and a weaker
northerly wind, which favors the production and accumulation of haze over
the NCP. A linear baroclinic model simulation reproduced the observed
north–south circulation system reasonably well and supports the diagnostic
analysis. Quasi-geostrophic vertical pressure velocity diagnostics were used
to quantify the contributions to the north–south circulation system made
by large-scale adiabatic forcing and diabatic heating (Q). The results
indicated that the north–south circulation system is induced mainly by
diabatic heating related to precipitation over southern China, and the
effect of large-scale circulation is negligible. These results provide the
basis for a more comprehensive understanding of the mechanisms that drive
the formation of haze over the NCP.

Abstract. Resuspension of 137Cs from the contaminated ground
surface to the atmosphere is essential for understanding the environmental
behaviors of 137Cs and estimating external and inhalation exposure of
residents. Kajino et al. (2016) assessed the 137Cs resuspension flux
from bare soil and forest ecosystems in eastern Japan in 2013 using a numerical
simulation constrained by surface air concentration measurements. However,
the simulation was found to underestimate the observed deposition amounts by
2 orders of magnitude. The reason for this underestimation is that the
simulation assumed that resuspended 137Cs is carried by submicron
aerosols, which have low deposition rates. Based on the observational
indications that soil dust and bioaerosols are the major carriers of
resuspended 137Cs, a new simulation is performed with higher deposition
rates constrained by both surface concentrations and deposition amounts. In
the new estimation, the total areal annual resuspension of 137Cs in
2013 is 25.7 TBq, which is equivalent to 0.96 % of the initial deposition
(2.68 PBq). Due to the rapid deposition rates, the annual redeposition
amount is also large at 10.6 TBq, approximately 40 % of the resuspended
137Cs. The resuspension rate through the atmosphere (0.96 % yr−1)
seems slow, but it (2.6 × 10−5 d−1) may not be negligibly
small compared to the actual decreasing trend of the ambient gamma dose rate
obtained in Fukushima Prefecture after the radioactive decay of 137Cs
plus 134Cs in 2013 is subtracted (1.0–7.9 × 10−4 d−1): resuspension can account for 1 %–10 % of the decreasing rate due
to decontamination and natural decay through land surface processes. The
current simulation underestimated the 137Cs deposition in Fukushima
city in winter by more than an order of magnitude, indicating the presence
of additional resuspension sources. The site of Fukushima city is surrounded
by major roads. Heavy traffic on wet and muddy roads after snow removal
operations could generate superlarge (approximately 100 µm in
diameter) road dust or road salt particles, which are not included in the
model but might contribute to the observed 137Cs at the site.
