The Scent

The Scent is a short fiction film following Sarah, who is in a relationship with Jake, a PhD student in art history, and works as an intern for a business firm. It unfolds as a flashback. Jake fetishizes Sarahs back and dislikes her idea of having a tattoo on it. John, Sarahs boss, evades the subject of a permanent contract despite calling her a perfect employee-to-be. Julia, a new employee and a freelance photographer, offers to draw a temporary tattoo on Sarahs back after they spend a day together, shooting photographs. Tension concealed behind a quiet facade emerges in successive events: Sarah breaks up with Jake following an argument over the tattoo, Julia disappears without notice, and Sarah gets fired (or quits as she puts it). Nevertheless, in the end, she finds peace by herself

Microfinance in mena region: a partial success

Microfinance is considered as effective and powerful tool for poverty eradication and women empowerment in developing countries. It helps poor by facilitating the access to financial resources; and providing a better life condition by increasing the household revenues and job creation for entrepreneurial poor. Existing literature about microfinance sector in Eastern and Southern Asia, as well as Latin America is somewhat rich, while this sector in Middle East and North African region (MENA) is merely studied and demands more investigations. The objective of this paper is trying to review the literatures and current findings about this sector in the MENA region

A Study of Written Errors of Iranian Learners: A Systematic Review

The collection of this systematic article was an attempt to show a survey of current activities in the field of error analysis in English language from 2012 to 2018 in Iran. In the country, English is being taught as Foreign Language from middle school. Khansir and Gholami Dashti (2014) mentioned that English accepted as language to pass in the examination. However, English system in this country often put on formal accuracy and teachers focus on the teaching of English grammar in their classes. Error analysis approach has been a widely discussed topic for more than 60 years over the world. However, all the findings of this paper from previous research works on error analysis can be good reasons in order to guide and help reduce such errors in the written language of Iranian students in EFL setting and the results of this work can also be used to as a guide for English learners over the world.  This article identifies and presents the major reasons leading to the English written errors among the Iranian learners. Finally, it reports the effective strategies and suggestions for helping the students to improve their English language. The researchers of this study studied 178 papers in this process and 37 of the papers were relevant

Scattering and Bound State Solutions of the Yukawa Potential within the Dirac Equation

In the presence of spin symmetry case, we obtain bound and scattering states solutions of the Dirac equation for the equal scalar and vector Yukawa potentials for any spin-orbit quantum number κ. The approximate analytical solutions are presented for the bound and scattering states and scattering phase shifts

Enhancing metallicity and basal plane reactivity of 2D materials via self-intercalation

Intercalation (ic) of metal atoms into the van der Waals (vdW) gap of layered materials constitutes a facile strategy to create new materials whose properties can be tuned via the concentration of the intercalated atoms. Here we perform systematic density functional theory calculations to explore various properties of an emergent class of crystalline 2D materials (ic-2D materials) comprising vdW homobilayers with native metal atoms on a sublattice of intercalation sites. From an initial set of 1348 ic-2D materials, generated from 77 vdW homobilayers, we find 95 structures with good thermodynamic stability (formation energy within 200 meV/atom of the convex hull). A significant fraction of the semiconducting host materials are found to undergo an insulator to metal transition upon self-intercalation with only PdS$_2$, PdSe$_2$, and GeS$_2$ maintaining a finite electronic gap. In five cases, self-intercalation introduces magnetism. In general, self-intercalation is found to promote metallicity and enhance the chemical reactivity on the basal plane. Based on the calculated H binding energy we find that self-intercalated SnS$_2$ and Hf$_3$Te$_2$ are promising candidates for hydrogen evolution catalysis. All the stable ic-2D structures and their calculated properties can be explored in the open C2DB database
