Torn between Cultures: Reading Shashi Tharoor’s Riot
Authors: M Athira
Published: January 2021

Shashi Tharoor is a distinctivevoice in the Postcolonial Indian literature in English with his remarkable contribution of more than 16 works of fiction and non-fiction. Postcolonialism refers to a set of theoretical concepts, approaches and interventions which deals with the diverse effects of the interaction between the colonizer and the colonized. History, politics and culture have always been a dominant preoccupation of the Indian English novelists. The compulsive obsession was perhaps inevitable since the genre originated and developed concurrently with the climatic phase of colonial rule. As a diplomat and writer, Shashi Tharoor has explored the diversity of culture in his native country. He has made his point in many of his interviews that the novel is full of collisions of various sorts- personal, political, cultural, emotional and violent. Riot is a novel about the ownership of history, about love, hate, cultural collision, religious fanaticism and the impossibility of knowing the truth. The novel chronicles the mystery of an American 24-year old lady, Priscilla Hart. The intention of this paper is to explore the cultural conflict between the East and the West and an attempt is made to examine Shashi Tharoor’s Riot as a conveyor of the various distinguishable features to the divergent cultures. The characters of Riot are facing problems and striving to achieve their identities as Indians and as individuals in Indian society. Lakshman, though an educated Indian, cannot share his intellectual ideas with any fellow Indians, but feels quite comfortable with Priscilla, an American lady. Yet, he cannot completely forego his Indian identity and is aware of their irreconcilable gap between their culture, values and outlook towards life.
Oh, Mother, Who Art Thou? : The Heart of Maternal Darkness in the Short Stories of Katherine Mansfield
Authors: Sarkar Anindita
Published: January 2021

Our culture assumes: No love is as great as that of a mother for her child. Motherhood has been perpetually associated with self-effacement and self-abnegation. Adrienne Rich while making a distinction between the actual lived experience of a mother and the institution of motherhood has argued that motherhood is a cultural construct and a far cry from the real experience of mothering. This article traces and examines representations of motherhood in the select short stories of Katherine Mansfield, in the light of Adrienne Rich’s theories in Of Woman Born. Much like Adrienne Rich, Mansfield discredits the traditional assumption that to be a mother is an essential pre-requisite to be a ‘real woman’. Mansfield’s women characters unleash a plurality of voices that aid the readers at viewing maternity as an ambiguous experience. Instead of romanticizing and idealizing the mother-daughter relationship, she offers a problematic connection between both the figures, often pitting them as rivals against each other. Her women characters progressively revolt from within the four walls of the household by their intermittent display of anger and deliberate attempts at failing to conform to the monolithic ideals of femininity.

Identify and Self-Search in Margaret Atwood’s The Handmaid’s Tale
Authors: Sandhu Shubhpreet
Published: January 2021

This paper attempts to capture the social status, domination of women by men faced by Offred, the protagonist of the sixth best seller novel by the Canadian author Margaret Atwood. The famous fantasy fiction The Handmaid’s Tale is written in the dystopian tradition.Through this novel, she has penned powerfully her social concern regarding the social status, domination, the mental turmoil and the identity crises of women in a male – dominated society and their consequent struggle to overcome this domination, repression and subjugation through many modes of escape strategies. This kind of struggle gives them power to speak against their situation and change their self to enable them to lead a dignified life in the same society. Six years before the publication of this novel, Margaret Atwood had commented on the writing of fiction in a way that seems to anticipate the novel. She comments “What kind of world shall you describe for your readers? The one you can see around you or the better one you can imagine? If only the latter, you’ll be unrealistic. If only the former, despairing, But It is by the better world we can imagine, that we judge the world we have”.
Multiculturalism in Kavita Dasvani’s Lovetorn
Authors: Kumar Jadhav Dr. Ganesh Vijay
Published: January 2021

Multiculturalism is a mechanism of interconnected ingredients and their experiences with each other as well as with the present world. It is a kind of respecting others’ very existence and identity. In specific ethnic minorities especially the women and low caste people are not identified with their self or existence. Respect is the practice which teaches to treat others with some reverence and modesty. It protects and values the dignity and social worth of an individual. It also acknowledges the social differences, because every group has its own specificity. Multiculturalism considers it because the minorities’ contribution to the society is empowering the society and taking it to a position of next and better destination. Uma Parmeshwran rightly argues in her article, “Home is home where your feet are, and may your heart be there too” that “literature can play an important role since literature not only reflects persistence and change in society but also can lead society to a better appreciation of its multicultural and ethno-centered fabric. The ethnic emigrant writer either writes about the country in which he is presently residing, like the main stream writers do, and thus try to be like ‘them’ or he can write about his ethnic world and be different” (31). In the present paper the major focus is on the multicultural aspects in context with various situations. Characters behaviour in different multicultural situations is the angle of analysis of the researcher.

Authors: Bariyah Shohihatun , Simatupang Lisnawaty
Published: January 2021

The effect of various types of mineral acids in activating the silica of volcanic ash of Mount Sinabung has been carried out. The use of various types of mineral acids is aimed at reducing impurities in the form of metals contained in the ash so that it can increase the SiO2 content in the ash. In the treatment, volcanic ash is prepared beforehand by grinding and sieving with a 200 mesh sieve. The sieved ash was then added with mineral acids, namely HCl, HNO3 and concentrated H2SO4 and heated at 100oC for 2 hours. After that, it was neutralized with distilled water and in an oven at 120oC for 6 hours and characterized using XRF to determine the impurities that had been lost. Based on the results obtained using XRF characteristics, the SiO2 content of volcanic ash activated with HCl was 80,23%, HNO3 was 77,23% and H2SO4 was 76,89%. This shows that activation using HCl is more optimal than using HNO3 and H2SO4.

Authors: Susilowati Indah , Fachrunnisa Olivia , BM Nugroho Sumarjiyanto
Published: January 2021

The level of corruption in ASEAN countries, especially ASEAN 5, namely Indonesia, Malaysia, Thailand, Vietnam, and the Philippines, although gradually declining but still in the high category. This study aims to analyze the factors that influence the level of corruption in ASEAN-5 countries (Indonesia, Malaysia, Thailand, Vietnam, and the Philippines). The level of corruption is proxied using the Corruption Perception Index (CPI), while the independent variable is internet users, and gender is proxied by female labor force participation and male labor force participation. The results show that the increasing number of internet users will reduce the level of corruption as indicated by the increased CPI value. As for gender, increasing female labor force participation will reduce the level of corruption, but the opposite result is shown by the participation of the male labor force. The policy implication of this study is the need to expand the use of the internet and provide wider opportunities for women to work, especially in public offices, to reduce the level of corruption
A Metaheuristic Approach to the C1S Problem
Authors: Abo-Alsabeh Rewayda , Salhi Abdellah
Published: January 2021

Given a binary matrix, finding the maximum set of columns such that the resulting submatrix has the Consecutive Ones Property (C1P) is called the Consecutive Ones Submatrix (C1S) problem. There are solution approaches for it, but there is also a room for improvement. Moreover, most of the studies of the problem use exact solution methods. We propose an evolutionary approach to solve the problem. We also suggest a related problem to C1S, which is the Consecutive Blocks Minimization (CBM). The algorithm is then performed on real-world and randomly generated matrices of the set covering type.

Authors: Abood Zainab A. , Taher Hazeem B. , Ghani Rana F.
Published: January 2021

Intelligent Transportation Systems (ITS) have been developed to improve the efficiency and safety of road transport by using new technologies for communication. Vehicle to Vehicle (V2V) and Vehicle to Infrastructure (V2I) are a subset of ITS widely used to solve different issues associated with transportation in cities. Road traffic congestion is still the most significant problem that causes important economic and productivity damages, as well as increasing environmental effects. This paper introduces an early traffic congestion alert system in a vehicular network, using the internet of things (IoT) and fuzzy logic, for optimizing the traffic and increasing the flow. The proposed system detects critical driving conditions, or any emergency situation blocking the road, and broadcasts remote warnings to the following vehicles. Since not all vehicles are equipped with new technologies, Liquid Crystal Display (LCD) fixed on the roads displays the alert to warn the other vehicles which have neither communication nor sensors. The system was designed with Raspberry Pi 3 Model B equipped with sensors and GPS module to emulate real-world vehicles. The results and observations collected during the experiments showed that the proposed system is able to monitor the road conditions, detect the emergency situation, and broadcast a warning message to the approaching vehicles.

BAGAIMANA INOVASI GAGAL: PEMBELAJARAN DARI KLASTER INDUSTRI SARUNG MAJALAYA
Authors: Adharina Nabilla Dina , Seruni Puri
Published: January 2021

Pentingnya peran inovasi dalam mendorong pertumbuhan ekonomi menekankan kebutuhan lokal dan wilayah untuk menciptakan lingkungan yang nyaman bagi perkembangan inovasi. Klaster industri, melalui kedekatan spasialnya menjanikan lingkungan yang dapat memelihara perkembangan inovasi. Namun, menggunakan kasus klaster industri Sarung Majalaya, dengan pendekatan deduktif dan metode kualitatif, penelitian ini mendapatkan bahwa kedekatan spasial bukan satu-satunya faktor yang mendorong terjadinya inovasi. Terdapat faktor-faktor non-fisik yang memiliki peran penting di dalam proses difusi pengetahuan, yaitu proses yang menghasilkan inovasi. Faktor tersebut adalah kemampuan dalam memperoleh, mengasimilasi, dan transformasi pengetahuan baru. Kemampuan tersebut mewakili kemampuan serap atau daya serap dalam proses difusi pengetahuan. Keterbatasan kemampuan individu, kolektif, dan lingkungan pada kapasitas tersebut menyebabkan proses difusi pengetahuan terhambat dan inovasi tidak berkembang di dalam klaster industri Sarung Majalaya. Sebagai pertimbangan kebijakan, mendorong inovasi dalam klaster dapat dilakukan melaui pengembangan infrastruktur, baik infrastruktur dasar serta infrastruktur di bidang penelitian dan pengembangan yang berkaitan dengan industri di dalamnya. Selain itu, adaptasi kolektif juga ternyata penting dalam proses difusi pengetahuan sehingga kapasitas sosial pelaku ekonomi di dalam kawasan perlu diderkuat. 

The importance of innovation in driving economic growth emphasizes the need for local and regional to create a convenient environment for innovation development. Industrial cluster, through spatial proximity, promises the environment nurturing innovation. However, by using industrial klaster of Sarung Majalaya, incorporating a deductive approach and qualitative method, this study found that spatial proximity is not the only factor promoting innovation. There are non physical factors playing important role in a process named knowledge diffusion which creates innovation. They are the capacities of knowledge acquirement, knowledge assimilation, and knowledge transformation which represent the absortive capacity in knowledge diffusion. As a policy consideration, promoting innovation within cluster can be conducted by developing basic infrastructure as well as research and development infrastructure. Furthermore, collective adaptation also plays an important role in the process of knowledge diffusion hence social capacity in the cluster should be strengthened.

Se examinó el 38,4% de la población total, encontrándose un notable número de longevos, con escasa o ninguna manifestación arteriosclerótica.

Se estudiaron 20 longevos con edades entre 81 y 121 años de edad.

Todos los ancianos parecen tener tendencia a la hipercoagulabilidad sanguínea y los niveles de lípidos sanguíneos están por encima de lo normal, aunque sin cifras manifiestamente elevadas.

En general, todos los ancianos gozan de exente salud.

Se propone la necesidad de un estudio más amplio, sobre aspectos genéticos, ecológicos y metabólicos de estos habitantes.

Con el objetivo de evaluar las ventajas que ofrece la prostatectomía transcapsular con ligadura previa del pedículo, se efectuó este tipo de intervención. En 70 se terminó exitosamente la operación y los resultados son referidos a este número de casos; en los 10 restantes no fue posible llevarla a acabo por fibrosis y adherencias prostáticas.

La técnica es simple en cuanto a ejecución y los resultados de las pruebas de control relacionadas con sangrado y tiempo de permanencia de la sonda demuestran que hay menor riesgo de hemorragia en el trans y en el postoperatorio y que es menor el tiempo de permanencia de la sonda, con relación a otras técnicas.

Las complicaciones postoperatorias fueron mínimas y sólo un paciente de los 70, falleció por insuficiencia cardíaca durante el acto quirúrgico. El tiempo de hospitalización fluctuó entre 6 y 10 días (pacientes privados y hospitalizados).

Presentamos el estudio de diez pacientes con insuficiencia renal crónica de variada etnología, a quienes se les sometió a tratamiento con hemodiálisis. Los resultados han sido satisfactorios, consiguiendo la rehabilitación de algunos enfermos (7).

En los otros (3), los malos resultados fueron debidos a las pésimas condiciones en se encontraban antes de comenzar el tratamiento. Creemos que es posible en el futuro mejorar la cifra de éxitos, escogiendo mejor a los pacientes. Se señala también la técnica del dializado y sus indicaciones

Günümüzde yolcu taşımacılığında demiryollarının payı giderek artmaktadır. Yolcu talebinin karşılanması için uygun planlamaların belirlenmesi gereklidir. Kapasiteyi karşılayacak planlamaların oluşturulması hem talebi karşılayacak hem de yatırımlarda uygun kararların alınmasını sağlayacaktır. Bu çalışmada, demiryolu yolcu taşımacılığı üzerinde etkili olan değişkenler kullanılarak demiryolu yolcu sayısının tahmin edilmesi amaçlanmıştır. Yolcu talebinin belirlenmesi için Çok Değişkenli Regresyon (ÇDR) analizi ve Yapay Sinir Ağları (YSA) ile iki farklı model oluşturulmuştur. İki model içinde tahmin değerleri belirlenmiştir. Hata kareleri ortalaması (MSE) ve belirleme katsayısı (R^2), performans kriterlerini, dikkate alarak en uygun tahmin YSA ile elde edilmiştir. Talep tahmininde YSA kaynak olarak kullanılabileceği görüşüne varılmıştır.

Bu çalışmada nokta direnç kaynaklı DP1200 çeliğinin ideal çekme makaslama dayanımını elde etmek için farklı kaynak akımı ve elektrot basıncı parametrelerinin optimizasyonuna odaklanılmıştır. Kaynak prosesleri 5 kA ve 7 kA kaynak akımlarında, 2-6 bar elektrot basınçlarında gerçekleştirilmiştir. Kaynak parametrelerinin çekme makaslama dayanımı üzerindeki etkileri çoklu doğrusal regresyon analizi ile incelenmiştir. Yapılan bu analiz ile elde edilen korelasyon tablosu ve ANOVA analiz değerleri yorumlanmıştır. Kaynak parametrelerinin önem derecesi belirlenerek, çekme makaslama dayanımı üzerindeki etkileri karşılaştırılmış ve belirlenen etki değerlerine göre çoklu doğrusal regresyon modeli oluşturulmuştur. Deneysel sonuçlar çekme makaslama dayanımını etkileyen en önemli değişkenin kaynak akımı olduğunu göstermiştir. Kaynak akımı arttıkça çekme makaslama dayanımı artmıştır. Özellikle yüksek kaynak akımı değerinde, elektrot basıncının kritik değerine kadar çekme makaslama dayanımının arttığı, fakat kritik değerinin üzerinde dayanımda düşüş olduğu görülmüştür. Sıçramanın çekme makaslama dayanımı üzerinde negatif etkiye sahip olduğu gözlenmiştir.

Published: January 2021

Sanayi atıkları ve diğer atıklardan kaynaklanan çevre kirliliği, günümüzün en önemli sorunlarından biridir. Ağır metaller; toprak, hava ve su için önemli kirleticiler arasında yer almaktadır. Atık su arıtımında ana odak noktası olan ağır metallerden biri de kromdur. Endüstriyel atık sularda hem üç değerlikli hem de altı değerlikli krom formları mevcut olsa da; altı değerlikli formun kanserojen özellikleri nedeniyle daha tehlikeli olduğu düşünülmektedir. Bu çalışmada, Cr (VI) iyonunun atık sulardan etkili bir şekilde giderilmesi için adsorban olarak yaygın kullanım alanına sahip ve düşük maliyetli olan zencefil tozu kullanılmıştır. Batch (kesikli) yöntemi ile temas süresi, pH, adsorban dozu, kromun başlangıç konsantrasyonu ve sıcaklık parametrelerinin adsorpsiyon üzerindeki etkileri araştırılmış ve optimum koşullar belirlenmiştir. Bu çalışmaya dayanarak, standart Gibbs serbest enerjisi (ΔG°), standart entalpi (ΔH°) ve standart entropi (ΔSG°) gibi termodinamik parametreler değerlendirilmiştir. Adsorpsiyon kinetiği; pseudo birinci derece, pseudo ikinci derece kinetik modeli ve partikül içi difüzyon modeli ile analiz edilerek, Pseudo ikinci derecede kinetik modelin Cr (VI) adsorpsiyonunu en etkili şekilde açıkladığı bulunmuştur. Ayrıca adsorpsiyon denge çalışmalarını tanımlamak için Langmuir, Freundlich, Dubinin-Radushkevich, Temkin izotermleri incelenmiş ve Langmuir izoterminin diğer izoterm modellere göre daha iyi uyum gösterdiği belirlenmiştir. Sonuç olarak, zencefil tozunun düşük maliyetli bir alternatif olarak krom içeren atık suların arıtılmasında verimli bir şekilde kullanılabileceği görülmektedir.

Os ambientes recifais são caracterizados como formações de fundo consolidado de origem orgânica e/ou inorgânica. Em costões rochosos, fatores bióticos e abióticos determinam a sua biodiversidade. Na praia do Forno, onde o fenômeno da ressurgência ocorre, a assembleia de peixes recifais foi analisada por meio de censo visual. A cobertura bentônica do substrato foi classificada em quatro categorias. O uso do substrato foi determinado pela abundância relativa das espécies em cada um de seus tipos. Um total de 5414 indivíduos pertencentes a 31 espécies de peixes recifais foi observado. Os resultados demonstraram que a preferência por habitats, caracterizados pela cobertura por organismos bentônicos, foi um fator importante na determinação da composição da assembleia de peixes recifais, em uma microescala. A escolha de um habitat dentre os diversos tipos de substrato, poder ser em sua maior parte explicada pela disponibilidade de recursos alimentares.

RESUMEN Antecedentes. En México las inmunodeficiencias primarias o errores innatos de la inmunidad (EII) se han reportado desde el primer informe de la Sociedad Latinoamericana de Inmunodeficiencias Primarias (LASID, Latin American Society for immnunodeficiencies). En los últimos años se ha observado como diferentes hospitales de diferentes regiones de México se han afiliado al registro de las EII en la plataforma LASID, lo cual refleja objetivamente un mayor número de pacientes diagnosticados con EII.Resultados. El Hospital Pediátrico de Sinaloa (HPS) inició su afiliación al registro de pacientes con EII en la plataforma de LASID hace tres años, durante este periodo se inició el abordaje, diagnóstico y tratamiento de casos con EII. En este periodo se han diagnosticado y tratado doce casos con EII en el HPS. El rango de edad al momento del diagnóstico fue de 2 días a 16 años, el rango de inicio de los síntomas de 19 días a 4 años, con predominio del género masculino con 67%. La EII más frecuente fue la deficiencia predominantemente de anticuerpos (33.3%), seguida de defectos en fagocitos en número o función (16.6%), desordenes autoinflamatorios (16.6%), inmunodeficiencias que afectan la inmunidad celular y humoral (16.6%), inmunodeficiencias combinadas asociadas a hallazgos sindromáticos (8.3%) y defectos en la inmunidad intrínseca e innata (8.3%). El 84% de los pacientes recibió inmunoglobulina intravenosa. Se identificó la variante patogénica en el gen WAS en un caso con síndrome de Wiskott-Aldrich. Un paciente recibió trasplante de células progenitoras hematopoyética El 33.3% de los pacientes fallecieron, 25% por sepsis y el 8.3% por hemorragia masiva.Conclusiones. El registro de las EII en los centros hospitalarios de una nación permite conocer datos epidemiológicos, incidencia, prevalencia, diagnóstico y tratamiento que favorecerán al desarrollo de nuevas políticas sanitarias para la obtención de recursos y herramientas para mejorar los modelos de atención y tratamiento de los EII. Resaltamos la importancia de que cada centro hospitalario de México registre EII en el registro en línea de LASID.
