Assessment of Fatty Acids Profile and Omega-3 Polyunsaturated Fatty Acid Production by the Oleaginous Marine Thraustochytrid Aurantiochytrium sp. T66 Cultivated on Volatile Fatty Acids
Authors: Patel Alok , Rova Ulrika , Christakopoulos Paul , Matsakas Leonidas
Published: April 2020

Thraustochytrids are considered natural producers of omega-3 fatty acids as they can synthesize up to 70% docosahexaenoic acids (DHA) of total lipids. However, commercial and sustainable production of microbial DHA is limited by elevated cost of carbon substrates for thraustochytrids cultivation. This problem can be addressed by utilizing low-cost renewable substrates. In the present study, growth, lipid accumulation and fatty acid profiles of the marine thraustochytrid Aurantiochytrium sp. T66 (ATCC-PRA-276) cultivated on volatile fatty acids (C1, formic acid; C2, acetic acid; C3, propionic acid; C4, butyric acid; C5, valeric acid and C6, caproic acid) and glucose as control were evaluated for the first time. This strain showed an inability to utilize C3, C5 and C6 as a substrate when provided at >2 g/L, while efficiently utilizing C2 and C4 up to 40 g/L. The highest cell dry weight (12.35 g/L) and total lipid concentration (6.59 g/L) were attained when this strain was cultivated on 40 g/L of butyric acid, followed by cultivation on glucose (11.87 g/L and 5.34 g/L, respectively) and acetic acid (8.70 g/L and 3.43 g/L, respectively). With 40 g/L butyric acid, the maximum docosahexaenoic acid content was 2.81 g/L, corresponding to 42.63% w/w of total lipids and a yield of 0.23 g/gcell dry weight (CDW). This marine oleaginous microorganism showed an elevated potential for polyunsaturated fatty acids production at higher acetic and butyric acid concentrations than previously reported. Moreover, fluorescence microscopy revealed that growth on butyric acid caused cell size to increase to 45 µm, one of the largest values reported for oleaginous microorganisms, as well as the presence of numerous tiny lipid droplets.

Published: April 2020

In this study, an experimental, metallographic method for determining strain distribution in a cold extruded aluminum gear-like element, based on the dependence of recrystallized grain size on prior deformation, was devised in order to overcome design problems in manufacturing of complex parts where critical values of strain and stress could cause a fracture. The method was applied on a 99.5% aluminum bar subjected to cold, radial extrusion, in order to produce complex gear-like element. To reveal the strain and stress distribution in specimens, the calibration and flow curves were first obtained by uniaxial compression (Rastegaev test). Afterwards, the grain size in different parts of the gear section was examined, the strain and stress distributions were calculated, and the results were confirmed by microhardness measurements. It was found that grain size, strain, stress, and microhardness considerably differed throughout the cross-section of the gear. The coarsest grain, and thus the lowest strain zone, was obtained in the central part of the tooth and in the zone between teeth. Conversely, the finest grains appeared in the highest strain zone at the specimen surface, particularly in the root of the teeth. Furthermore, results were supported by microhardness measurements, i.e., microhardness corresponded to grain size and strain hardening. Finally, the real view of material flow in the complex extruded part was successfully obtained by the metallographic method.
Consistency Analysis of Remote Sensing Land Cover Products in the Tropical Rainforest Climate Region: A Case Study of Indonesia
Authors: Kang Junmei , Wang Zhihua , Sui Lichun , Yang Xiaomei , Ma Yuanzheng , Wang Jun
Published: April 2020

Land cover changes in tropical rainforest climate zones play an important role in global climate change and the functioning of the Earth’s natural system. Existing research on the consistency of different land cover products has mainly focused on administrative divisions (continental or national scales). However, the ongoing production of large regional or global land cover products with higher resolutions requires us to have a better grasp of confusing land types and their geographical locations for different zoning (e.g., geographical zoning) in order to guide the optimization of strategies such as zoning and sample selection in automated land cover classification. Therefore, we selected the GlobeLand30-2010, GLC_FCS30-2015, and FROM_GLC2015 global land cover products with a 30-m resolution covering Indonesia, which has a tropical rainforest climate, as a case study, and then analyzed these products in terms of areal consistency, spatial consistency, and accuracy evaluation. The results revealed that (a) all three land cover products revealed that forest is the main land cover type in Indonesia. The area correlation coefficient of any two products is better than 0.89; (b) the areas that are completely consistent among the three products account for 58% of the total area of Indonesia, mainly distributed in the central and northern parts of Kalimantan and Papua, which are dominated by forest land types. The spatial consistency of the three products is low, however, due to the complex surface types and staggered distributions of grassland, shrub, cultivated land, artificial surface, and other land cover types in Java, eastern Sumatra, and the eastern, southern, and northwestern sections of Kalimantan, where the elevation is less than 200 m. Given these results, land cover producers should take heed of the classification accuracy of these areas; (c) the absolute accuracy evaluation demonstrated that the GLC_FCS30-2015 product has the highest overall accuracy (65.59%), followed by the overall accuracy of the GlobeLand30-2010 product (61.65%), while the FROM_GLC2015 exhibits the lowest overall accuracy (57.71%). The mapping accuracy of the three products is higher for forests and artificial surfaces. The cropland mapping accuracy of the GLC_FCS30-2015 product is higher than those of the other two products. The mapping accuracy of all products is low for grassland, shrubland, bareland, and wetland. The classification accuracy of these land cover types requires further improvement and cannot be used directly by land cover users when conducting relevant research in tropical rainforest climate zones, since the utilization of these products could lead to serious errors.
A estilística do roteiro das séries contemporâneas: análise do episódio Chicanery, de Better Call Saul
Authors: Silva Marcel Vieira Barreto , Aragão Quirino Rodrigo
Published: April 2020

Este artigo tem por intuito analisar o roteiro literário de Chicanery, quinto episódio da terceira temporada da série Better Call Saul (2015-atual), um spin-off da renomada série Breaking Bad (2008-2013), agora em uma coprodução do canal a cabo AMC com a Netflix. Para tanto, buscamos identificar os aspectos que impulsionaram a escrita do roteiro de séries contemporâneas, a partir da sofisticação do estilo e da narrativa, em um processo que levou ao desenvolvimento de um modelo de escrita mais centrado na construção da atmosfera e na subjetivação dos personagens que na descrição objetiva da cena dramática. Para compreender essa estilística particular, observamos, metodologicamente, de que forma elementos incomuns à ortodoxia do roteiro, como o uso de interjeições, interrogações e figuras de linguagem, além da presença ostensiva de um narrador polifônico, operam na construção do roteiro de Chicanery, inserindo interferências épicas e líricas no seio do texto dramático. Por fim, demonstramos as funções desses elementos atmosféricos e subjetivos para a roteirização audiovisual contemporânea, reforçando ainda a importância das análises textuais de roteiros literários para a compreensão das estratégias de serialização televisiva.

Authors: Shaheen Safdar , Yousaf Muhammad , Jalil Mudassar
Published: April 2020

Free and fair elections are indispensable to quantify the sentiments of the populace for forming the government of representatives in democratic countries. Due to its procedural variation from country to country and complexity, to maneuverer, it is a challenging task. Since the Orthodox paper-based electoral systems are slow and error-prone, therefore, a secure and efficient electoral system always remained a key area of research. Although a lot of literature is available on this topic. However, due to reported anomalies and weaknesses in American and France election in 2016, it once again has become a pivotal subject of research. In this article, we proposed a new secure and efficient electronic voting scheme based on public key cryptosystem dubbed as Number Theory Research Unit (NTRU). Furthermore, an efficient and robust three factors authentication protocol based on a personalized memorable password, a smartcard, and bioHash is proposed to validate the legitimacy of a voter for casting a legal vote. NTRU based blind signatures are used to preserve the anonymity and privacy of vote and voters, whereas the proficiency of secure and efficient counting of votes is achieved through NTRU based homomorphic tally. Non-coercibility and individual verifiability are attained through Mark Pledge scheme. The proposed applied electronic voting scheme is, secure, transparent and efficient for large scale elections.
Direct Text Classifier for Thematic Arabic Discourse Documents
Authors: Nahar Khalid , Al-Khatib Ra’ed , Al-Shannaq Moy'awiah , Daradkeh Mohammad , Malkawi Rami
Published: April 2020

Maintaining the topical coherence while writing a discourse is a major challenge confronting novice and non-novice writers alike. This challenge is even more intense with Arabic discourse because of the complex morphology and the widespread of synonyms in Arabic language. In this research, we present a direct classification of Arabic discourse document while writing. This prescriptive proposed framework consists of the following stages: data collection, pre-processing, construction of Language Model (LM), topics identification, topics classification, and topic notification. To prove and demonstrate our proposed framework, we designed a system and applied it on a corpus of 2800 Arabic discourse documents synthesized into four predefined topics related to: Culture, Economy, Sport, and Religion. System performance was analysed, in terms of accuracy, recall, precision, and F-measure. The results demonstrated that the proposed topic modeling-based decision framework is able to classify topics while writing a discourse with accuracy of 91.0%.
A New Metric for Class Cohesion for Object Oriented Software
Authors: Gosain Anjana , Sharma Ganga
Published: April 2020

Various class cohesion metrics exist in literature both at design level and source code level to assess the quality of Object Oriented (OO) software. However, the idea of cohesive interactions (or relationships) between instance variables (i.e., attributes) and methods of a class for measuring cohesion varies from one metric to another. Some authors have used instance variable usage by methods of the class to measure class cohesion while some focus on similarity of methods based on sharing of instance variables. However, researchers believe that such metrics still do not properly capture cohesiveness of classes. Therefore, measures based on different perspective on the idea of cohesive interactions should be developed. Consequently, in this paper, we propose a source code level class cohesion metric based on instance variable usage by methods. We first formalize three types of cohesive interactions and then categorize these cohesive interactions by providing them ranking and weights in order to compute our proposed measure. To determine the usefulness of the proposed measure, theoretical validation using a property based axiomatic framework has been done. For empirical validation, we have used Pearson correlation analysis and logistic regression in an experimental study conducted on 28 Java classes to determine the relationship between the proposed measure and maintenance-effort of classes. The results indicate that the proposed cohesion measure is strongly correlated with maintenance-effort and can serve as a good predictor of the same.
Gene Expression Prediction Using Deep Neural Networks
Authors: Bhukya Raju , Ashok Achyuth
Published: April 2020

In the field of molecular biology, gene expression is a term that encompasses all the information contained in an organism’s genome. Although, researchers have developed several clinical techniques to quantitatively measure the expressions of genes of an organism, they are too costly to be extensively used. The NIH LINCS program revealed that human gene expressions are highly correlated. Further research at the University of California, Irvine (UCI) led to the development of D-GEX, a Multi Layer Perceptron (MLP) model that was trained to predict unknown target expressions from previously identified landmark expressions. But, bowing to hardware limitations, they had split the target genes into different sets and constructed separate models to profile the whole genome. This paper proposes an alternative solution using a combination of deep autoencoder and MLP to overcome this bottleneck and improve the prediction performance. The microarray based Gene Expression Omnibus (GEO) dataset was employed to train the neural networks. Experimental result shows that this new model, abbreviated as E-GEX, outperforms D-GEX by 16.64% in terms of overall prediction accuracy on GEO dataset. The models were further tested on an RNA-Seq based 1000G dataset and E-GEX was found to be 49.23% more accurate than D-GEX.
The Problem of Immigrant Identity In Buddha of Suburbia By Hanif Kureishi
Authors: KARA Gökçen
Published: April 2020

The present study aims to lay bare how Kureishi examines the problem of immi-grant identity in The Buddha of Suburbia. Immigrants leave their homeland vol-untarily or involuntarily to have a better life. They can neither continue their own culture nor become involved in the new culture. In Homi Bhaba's words, they experience ‘in betweenneess’. This study refers to Homi Bhabha's main ideas about hybridity, mimicry, liminality and the third space. In this study Bhabha's theories will help highlight how Kureishi's characters create liminal areas and realize their identities in these areas. For the characters in the novel, migration is a never-ending process in which they live simultaneously between the past and the present. Because they have been subjected to many discrimination such as race, language, religion, color and have always been declared ‘other’ in society. Karim is one of the major characters who suffers from being stuck in between. Although he tries to pretend to be British by rejecting the culture of his father, who is Indian, he is never accepted by the racist society in which he lives and he stays in this liminal area without an identity.

The Past Victim, the Future Abuser
Authors: Firoozabadi Ali
Published: April 2020

Background: Childhood trauma exerts a significant effect on psychological life of people. It is a ubiquitous phenomenon. We face a social epidemic with serious consequences that shatter the life of survivors. Victimization in early years of life entraps the individuals in the victim-rescuer-abuser triangle. Many perpetrators and criminals have had history of childhood abuse. The main objective of this study was the assessment of patients with a history of child abuse who behaved in abusive manner in adulthood. Methods: By reviewing the files of 3694 patients referred to my outpatient private clinic, I tried to gather data to answer the questions related to this study including history of abuse, victimization, substance abuse, and the percent of patients who were involved in abusive behaviors in adulthood. Results: In total, 1075 patients reported a history of some abuse during childhood (29.10%). Of them, 19.44% (total = 209, 78 men and 131 women) behaved as an abuser for most of their life. The prevalence of substance abuse in people with history of abuse was 36.6% compared to 28.36% in those without. The prevalence of acting as an abuser and perpetrator in adult life was 27.5%, 19.5%, 18.4% and 11.11% among the divorced, married, single and widowed respectively. Conclusion: This preliminary study showed that a significant number of patients with history of childhood abuse involved in abusive behavior and victimization of others in adulthood. Paying attention to this issue by mental health practitioners and policy makers can prevent the intergenerational transmission of abuse and development of a more peaceful society.

Authors: Silveira Daniel da Silva , Fonseca Daniele Amaral
Published: April 2020

Neste artigo, apresentamos um recorte dos resultados de uma pesquisa que teve por objetivo compreender as percepções dos estudantes de graduação em relação ao uso das tecnologias digitais no processo formativo no Ensino Superior. A pesquisa é balizada pela teoria da Biologia do Conhecer de Humberto Maturana e Francisco Varela em que o explicar científico é fundamentado na objetividade entre parênteses, na qual não existe uma objetividade independente do observador para validar o explicar, pois este está imerso na explicação. O estudo teve como perspectiva metodológica o conversar que se estabeleceu a partir da implementação de dois fóruns no Ambiente Virtual Moodle nas disciplinas de Métodos Numéricos Computacionais e Geometria Dinâmica I de uma Universidade Federal. Para análise dos registros gerados nos fóruns utilizou-se a técnica do Discurso do Sujeito Coletivo (DSC). Os resultados revelaram pelo DSC intitulado “Aprender matemática por meio das tecnologias digitais” que os estudantes perceberam a contribuição da tecnologia digital no processo de ensinar matemática de forma motivadora, potente e com desafios e que os artefatos tecnológicos não foram utilizados apenas como recursos para executar tarefas, mas se constituíram em potencializadores de transformações cognitivas no aprender matemática.

Bio-historia, biopolítica y clínica médica
Authors: Raffin Marcelo
Published: April 2020

Este artículo propone una exégesis de dos de los hitos conceptuales fundamentales con los que Foucault llevó adelante su investigación sobre la medicina como campo de producción de lo “humano” en la modernidad: por un lado, el delineamiento del individuo en el nacimiento de la clínica moderna y, por el otro, el surgimiento de la figura de lo “humano” a partir del proceso de medicalización como correlato de lo que el filósofo denomina la bio-historia. A tal fin, en primer lugar, se analiza la producción de lo “humano” bajo la noción de “individuo” como consecuencia de la “mirada médica”, en Nacimiento de la clínica. Luego, se relaciona esa noción con la de “hombre”, que aparece como su corolario en Las palabras y las cosas, donde esta última figura cobra toda su significación como resultante de la positividad de las ciencias que se producen en tono de él. Finalmente, se realiza un examen de la producción de lo “humano” en las conferencias que Foucault pronuncia en la Universidad del Estado de Río de Janeiro, en 1974, donde la producción de lo “humano” va a aparecer ligada al paradigma de la biopolítica y, específicamente, en el caso de la medicina, de la “bio-historia”, que complementan y precisan los desarrollos previos.

El problema de las normas del decoro en los ensayos de David Hume sobre la crítica artística
Authors: Nicastro Felipe
Published: April 2020

El presente trabajo pretende matizar la dicotomía conservador/rupturista con la que se suele querer decidir la relación de los ensayos de critica artística de David Hume con el Clasicismo francés del siglo XVII y el Neoclasicismo europeo del XVIII. En este sentido, mis objetivos son: dar una imagen de conjunto de la crítica artística clasicista, haciendo hincapié en la reposición de los principios generales de lo que Jacques Rancière llama el “sistema de la poética de la representación”; analizar los textos de crítica artística de Hume a la luz de la bibliografía consultada para así poder cotejarla con la imagen del Clasicismo antes estudiada; señalar mi postura frente a la dicotomía conservador/rupturista con la que se busca definir a Hume en relación al Clasicismo, mostrando que las fuentes analizadas no permiten lecturas unilaterales, sino que, al contrario, proporcionan elementos heterogéneos que invitan a una comprensión más amplia de la relación entre la propuesta humeana y la clasicista.

A PARADOX OF EQUALITY AND ‘HER STORY’ IN AFRICA
Authors: E. Daramola Folashade
Published: April 2020

Gender equity and equality issues are essential to the social and economic life of every country. Gender equity can be viewed as the basis for the full promotion and improvement of the status of women in all areas, particularly in the distribution of power, influence and economic independence. The term equality can be seen as a human rights issue and as a precondition for and indicator of sustainable human development. Using the historical and analytical approach, this work, therefore, re-examines the challenges faced by African women in the social, political and economic spaces. Data collection is based on Government reports, Administrative reports and other relevant secondary sources gathered through a multidisciplinary approach. It can be deduced from this work that gender inequality has impeded socioeconomic development in Africa. Findings from this work have therefore stressed that the enhancement of women’s status in society would not in any way reduce the social, economic and political standing of men. The whole society stands to gain a lot and this will thereby accelerate the pace of development. Also, this work will bring to the fore that women control a marginal proportion of the nation’s economic resources and have therefore been particularly confronted by unprecedented social and economic hardship which has largely constrained their participation in various spheres of life. The economic hardship that has been persistently experienced has been more punitive for women, given the multiple demands and responsibilities they are confronted with. This has largely inhibited women’s drive towards personal empowerment and, consequently, effective participation in societal affairs. This work on gender inequality will, therefore, act as a catalyst to present-day women in Africa, to seek educational, economic, spiritual and political empowerment which could in the future lead to social justice, thereby fostering equality between the genders in all spheres of human endeavor.

The figure of Sethel in the Medinet Madi Manichaean Writings: A result of the influence of the Gnostic Sethianism? Observations on Manichaeism as a religious system
Authors: Dobkowski Mariusz
Published: April 2020

In the Manichaean Coptic Psalm-Book (c. ad 400) we find a hymn (PsB 144.1–146.13) addressed to Sethel/Seth. Hence, a French scholar, André Villey, titled it Hymne à Seth. This is an interesting work, since the biblical figure of Seth is the eponym of one of the two most important movements of Gnosticism, namely Sethianism. In my paper, firstly, I study the characteristics of the figure of Sethel/Seth in the Manichaean writings from Medinet Madi; secondly, I examine whether, as for Sethel/Seth, we can talk about the influence the Sethians on ‘the religion of Light’ or, on the contrary, whether his figure in the Manichaean writings was an original, Manichaean, reinterpretation. Finally, this analysis allows us to draw two important conclusions regarding Manichaeism as a religious system. The first of them is that the Manichaeans drew on a broad base of Judaeo-Christian literature, not only from Gnostic Sethianism. The other is that Manichaeism caused external figures such as Seth/Sethel to lose some of their characteristics in the process of being adapted to the needs of the mentioned religion.

Polip kolorektal merupakan benjolan yang sering ditemukan di saluran cerna, dibandingkan polip lain di saluran pencernaan. Polip kolorektal ada yang bersifat neoplastik, ada juga yang bukan. Polip yang neoplastik dapat berprogresi menjadi maligna. Klasifikasi polip kolorektal menurut WHO adalah adenoma, serrated dan hamartoma. Semua tipe tersebut mempunyai prognosis dan tata laksana yang berbeda. Endoskopi sering dilakukan pada pasien dengan polip kolorektal, tetapi apa yang ditemukan dari endoskopi tidak bisa membedakan tipe dari polip tersebut, sehingga diperlukan pemeriksaan patologi anatomi untuk kepastian tipe polip. Kata kunci : polip kolorektal, patologi, anatomi.
Hubungan antara Infeksi Cacing Usus dan Tuberkulosis
Authors: Yuliana Yuliana
Published: April 2020

Cacing usus masih sering diabaikan meskipun prevalensi kecacingan tinggi. Hal ini dikarenakan kurangnya edukasi mengenai beratnya konsekuensi infeksi cacing ini. Begitu juga dengan Mycobacterium tuberculosis (Mtb). Distribusi geografik kedua penyakit ini saling tumpang tindih, sehingga koinfeksi sering terjadi. Respons imun tubuh terhadap dua penyakit ini ternyata saling bertolak belakang. Infeksi cacing usus merangsang respons imun Th2 dan Treg. Kedua respons ini akan menekan imunitas Th1, yang diperlukan sebagai kontrol dari infeksi Mtb. Kondisi ini membuat kedua penyakit ini bisa menginfeksi satu individu di waktu yang bersamaan. Hal ini membuat penduduk di daerah endemis lebih rentan terhadap kedua penyakit ini. Dalam artikel ini, penulis mencoba membahas kedua penyakit ini dan respons tubuh terhadap mereka. Kata kunci : infeksi cacing usus, tuberkulosis, respon imun

Penyakit Hemolitik pada Bayi Baru Lahir
Authors: Sihombing Martina Rentauli , Sari Dominica Pita
Published: April 2020

Penyakit hemolitik pada bayi baru lahir adalah sindrom anemia hemolitik dan ikterus yang terjadi akibat destruksi eritrosit yang sudah dilapisi oleh antibodi. Patofisiologi pada penyakit ini adalah karena adanya proses imun yang dimulai saat terjadi sensitisasi pada kehamilan pertama saat darah janin yang memasuki sirkulasi ibu. Adanya ketidakcocokan golongan darah atau rhesus tersebut memicu proses imun ibu membentuk antibodi sehingga menyebabkan penghancuran eritrosit bayi. Hal ini dapat disebabkan oleh adanya ketidakcocokan golongan darah ABO, rhesus, atau golongan darah lainnya. Perbedaan golongan darah antara ibu dan bayi terjadi saat ada faktor golongan darah janin yang diwariskan dari ayahnya tidak dimiliki oleh ibu. Gejala yang timbul antara lain hiperbilirubinemia, anemia, hepatosplenomegali, dan lainnya. Pemeriksaan laboratorium yang berfungsi sebagai pemeriksaan penyaring adalah: Uji Rossete, uji Kleihauer-Betke (KB), flowsitometri dan tes antiglobulin indirek. Pemeriksaan rutin lainnya adalah pemeriksaan darah rutin, kadar bilirubin, golongan darah dan rhesus. Penatalaksanaan saat kehamilan dapat berupa transfusi intrauterin atau imunomodulasi, sementara penatalaksanaan paska kelahiran dapat dengan transfusi tukar, fototerapi atau pemberian imunoglobulin
