Plants as a Promising Reservoir of Tyrosinase Inhibitors
No full textThe process of melanogenesis, that takes place in the melanocytes of the epidermis, leads to hyperpigmentation. The biosynthetic pathway for production of melanin involves the enzyme tyrosinase that has been an attractive target for cosmaceutical research. Numerous synthetic, semisynthetic and natural, especially plant-based, inhibitors of tyrosinase have been reported in the literature. In plants, the secondary metabolites like flavonoids, chalcones, stilbenes, tannins, hydroquinone and kojic acid, etc... have been shown to possess the anti-tyrosinase activity. In the current review, we have covered the progress in this sphere that would be useful for not only further mechanistic investigations but also for the optimization of the structure of the metabolites for improved activity and selectivity. Thus the review presents a comprehensive report on tyrosinase inhibitors of plant origin reported in the extract form or as isolated compounds. Huge gap has been found between research and industry due to inconsistent pursual of the potent plant based extracts. There is a need to completely evaluate the extracts for structure optimization using molecular docking and evaluation of the safety inorder to benefit the industry with non toxic biological friendly products through invivo and exvivo optimization
In pursuit of 1 Sri Lanka: Lessons from a Malaysian counterpart
No full textThe quest for national unity has become a leadership challenge for successive leaders of both Malaysia and Sri Lanka. While the two countries record significant differences in contexts and background, the similarities are equally striking. The following is an article that is based on a two-country study undertaken by the author to unpackage and explore the "1Malaysia" Programme that was launched in 2009 following the election of Malaysian Prime Minister's, Tun Najib Razak into his first term in office. The author spent a two week resident attachment at the 1Malayisa Foundation in Malaysia in the summer of 2012 to study further the facets of the governance programme that had been formulated with the intention of resolving the ethnic tensions that have plagued Malaysia since it gained independence, or Merdeka. The purpose of the endeavour was three-fold: First, to identify and extract aspects of the 1Malaysia Programme as relevant to the Sri Lankan context so as to formulate a potential 1Sri Lanka programme that is cognizant of the variables at stake. Secondly, the article seeks to critique the already existent framework of the 1Malaysia Programme by providing recommendations for improvement where necessary. Third, to begin dialogue and deliberations on the rich learning and exchange that can be cultivated between the two countries by providing a framework for bilateral cooperation between the Governments of Malaysia and Sri Lanka
Salma la caperucita africana
No full textTraditional children's stories are characterized by moral teaching and didactic purposes. These folk tales are a broad-based source of inspiration for many authors who have created many adaptations, reinterpretations, updates and recreations of the original tales. Nowadays, children's stories help them develop their imagination and fantasy; explore not only their inner world but also the one outside using cross-curricular issues, such as multiculturalism. Therefore, children's literature is an excellent tool for understanding and exposing them to other cultures besides their own. This is the aim of the writer and illustrator Niki Daly, with his work Pretty Salma: A Little Red Riding Hood Story from Africa (2006). The author draws on the traditional tale of Little Red Riding Hood (story adapted many times by different writers and publishers), and rewrites/reinscribes the story introducing us a new Riding Hood called Salma, an African girl who belongs to another culture and has different customs to the traditional European Riding Hood. Thus the author presents a modern tale which has many differences but shares some similarities with the traditional one, and encourages interest and respect in African culture.Los cuentos infantiles tradicionales se caracterizan por transmitir una enseñanza moral y tener una finalidad didáctica. Estos cuentos tradicionales suponen una rica base y fuente de inspiración para muchos autores que crean multitud de adaptaciones, reinterpretaciones, actualizaciones y recreaciones de los cuentos originales. Hoy en día, los cuentos infantiles contribuyen a desarrollar la imaginación y fantasía de los niños, a crear sus propios mundos interiores y a pensar en lo que sucede en nuestro mundo mostrando temas transversales presentes en nuestra sociedad, como es el caso de la multiculturalidad. Por ello la literatura infantil y juvenil es un excelente instrumento para conocer y profundizar en otras culturas diferentes a la propia. Esto es lo que pretende el escritor e ilustrador Niki Daly, con su obra La pequeña caperucita africana (2006). El autor se inspira en el cuento tradicional de Caperucita Roja (cuento versionado multitud de veces por diferentes escritores y editores), y reescribe/ reinscribe la historia presentándonos a una nueva caperucita llamada Salma, una niña africana que pertenece a otra cultura y tiene otras costumbres diferentes a la caperucita tradicional europea. De este modo el autor nos presenta un cuento moderno que tiene muchas similitudes y diferencias con el cuento tradicional, y que fomenta el interés y el respeto hacia la cultura africana
Self and other in umaymah al-khamis’ salma al umaniyyah
No full textThis paper explores patterns and perspectives to the construction of Self and Other in Saudi women’s fiction through a close reading of one the works of one of the earliest female writers to emerge in the Kingdom. A study of how this female writer arrived at the construction of the Saudi ‘Self’ in contradistinction to the other raises pertinent questions on notions of identities across cultures and civilizations. The paper examines series of ‘external Others’, established by the author; Umaymah Al-Khamis, whose own literary exposition and journeys enabled her to depict the question of national identity from a new standpoint. It also gives a picture of ‘internal Other’ of women who, for whatever reason, have perceived themselves as occupiers of the peripheries of the society. It draws its theoretical framework from Edward Said and Michel Foucault. In Salma Al-Umaniyyah, Umaymah Al-Khamis exemplifies the slippery texture of the Self and Other as well as its implications for socio-cultural harmony in human societies. The paper consequently contemplates the following questions: Why is it that the existing studies on Saudi Arabian literature, dominated by male writers interested in entrenching male dominance, have ignored the expression of ‘Self’ and ‘Other’ in the literary tradition of the Kingdom? What extent is a ‘Self’ and ‘Other’ factor in the production and consumption of fiction in Saudi Arabia? Why is it that, the author or Salma Ai-Umaniyyah is interested in ‘Self’ and ‘Other’ in her creativity
Revising Trauma Theory: Trauma as Identity Construction and the Discontented Self in Fadia Faqir’s My Name is Salma (2007)
No full textThis essay will examine the concept of traumatic identity in My Name is Salma, exploring theories of traumatic identity and their relationship to the self in Arab Literature, the social context of the text and its historical resonance, and representation and identity via the female traumatic experience. The analysis will seek to reflect upon the impact and convergence of feminism, trauma and post colonialism within issues like the construction of the self, belonging, and the juxtaposition of homeland and exile. This essay argues, in part, that Arab women writers embrace trauma in their texts, while simultaneously critiquing the effects of trauma on the construction of personal identity. In particular, the work of Jordanian author, Fadia Faqir, in her novel, My Name is Salma (2007), provides a first-person narrative of the narrator and protagonist, Salma, who defines her personal identity as constructed from trauma, yet who is unable to process, mediate, or overcome her traumatic past. As she nevertheless attempts to construct a coherent narrative of self, the character of Salma allows readers insights into her thoughts, actions, and the way she views herself. This essay asserts further that the types of trauma that inform Salma’s narrative of self also speak to the experiences of many women in Arab states, such as the social stigmatization of so-called illegitimate birth, the violence of honour killing, racial abuse, Othering, and the dire circumstances and suffering inherent in life as a refugee
The psychological criticism of Ka Ranra Shwa, Salma Shaheen’s Novel
No full textThe Psychological criticism has trace back to the psychoanalytical thoughts which were presented by Fraed. After him, the neo-Freudians such as Adler and Jaang also contributed in the field on these theories. The Critics, apply particular psychological theory to psychological criticism to make the criticism on the author, according to the method and theories in this field, we have chosen the Pashto Novel, Ka Ranra Shwa by Salma Shaheen , farmer Director Pashto Academy, UOP. Published in 1998 AD in Lahore. Its story is based on the typical Pashtoon society where there every relation has a name, respect and position. Those relations and position affect the psychology of the society. The impact of the behavior and way of thoughts inspired the whole Pashtoon culture. This paper will discuss the Novel in the light of the standard made by Psychological criticism in order to explore the modern beauty of modern literary standards in the mentioned novel

Indigenous Ecocinema: Decolonizing Media Environments
No full textIntroducing the concepts of d-ecocinema and d-ecocinema criticism, Monani expands the purview of ecocinema studies and not only brings attention to a thriving Indigenous cinema archive but also argues for a methodological approach that ushers Indigenous intellectual voices front and center in how we theorize this archive. Its case-study focus on Canada, particularly the work emanating from the imagineNATIVE Film + Media Arts Festival in Toronto--a nationally and internationally recognized hub in Indigenous cinema networks--provides insights into pan-Indigenous and Nation-specific contexts of Indigenous ecocinema.
This absorbing text is the first book-length exploration foregrounding the environmental dimensions of cinema made by Indigenous peoples, including a particlarly fascinating discussion on how Indigenous cinema’s ecological entanglements are a crucial and complementary aspect of its agenda of decolonialism.

Quantification and modelling of organic micropollutant removal by reverse osmosis (RO) drinking water treatment
No full textReverse osmosis (RO) is the most promising membrane technology in organic micropollutants (MPs) removal of drinking water treatment. For 78 MPs, passage and removal were evaluated with an ESPA3 RO membrane and the robustness of RO against MPs was studied. The MPs were classified according to their charge and hydrophobicity. The results showed that the size of neutral compounds was negatively correlated with their passage. This correlation was weaker for neutral hydrophobic MPs than neutral hydrophilic MPs. The lowest passage (0.2%–4%) was displayed by anionic MPs because of electrostatic repulsion between the negatively charged solute and negatively charged membrane surface. Cationic MPs showed a higher passage (around 0.4%–40%) due to electrostatic sorption and Donnan exclusion. The relationship between physical-chemical properties of MPs and their passage was evaluated by the one-way analysis of variance (ANOVA). We performed a qualitative analysis of variables using Principal Component Analysis (PCA) in order to examine the physical-chemical properties of compounds that affect the membrane removal of MPs. After analysis with Multiple Linear Regression (MLR), we concluded that properties such as molecular width, equivalent molecular width, pKa and solubility can be considered as significant descriptors for prediction of the membrane removal. The influence of feed water temperature on MPs passage was also assessed. The results revealed that a rise of water temperature from 5 to 19 °C, increases the average passage of MPs by 6.5%.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Sanitary Engineerin
