Weakly polymatroidal ideals with applications to vertex cover ideals

In this paper we extend the concept of weakly polymatroidal ideals to monomial ideals which are not necessarily generated in one degree, and show that any ideal in this class has linear quotients. As an application we study some vertex cover ideals of weighted hypergraphs

Althusserian reading of The Handmaid's Tale

Louis Althusser (1918-1990) builds on the work of Jacques Lacan to understand the way ideology functions in society. He thus moves away from the earlier Marxist understanding of ideology. In the earlier model, ideology was believed to create what was termed "false consciousness", a false understanding of the way the world functioned. Althusser explains that for Marx "Ideology is [...] thought as an imaginary construction whose status is exactly like the theoretical status of the dream among writers before Freud. For those writers, the dream was the purely imaginary, i.e. null, result of the 'day's residues" (1971:108). Althusser, by contrast, approximates ideology to Lacan's understanding of reality, the world we construct around us after our entrance into the symbolic order. For Althusser, as for Lacan, it is impossible to access the real conditions of existence due to our reliance on language. This could be seen throughout the novel by Margaret Atwood who writes The Handmaid's Tale (1985) based on the concept of ideology. This is about how the heroine of the story and other women in the society are manipulated by the ideology of ruling class through a communist society. In such a world nothing is real and everything is just an illusion that is made by ruling class. The subjects trapped or forced to believe such misconceptions and unreality through different techniques that are employed by the rulers. The dominant forces and ideology are so strong that the subject at the end gets a new identity since she is required unconsciously without her knowing. The other aspect shown by this novel is the failure of revolution and communism in this society and persistence of capitalism that it never disappears

A Study of Idioms and Enigmas in Xollar Dialect

Abstract: Considering increasing development of Persian Language in the capital as well as immigrating villagers to metropolitans, there is a fear that many of authentic words, idioms and riddles in the ancient cultures will be forgotten and obsolete. Therefore in this paper for the first time it has been tried to collect idioms and riddles in one of original dialects survived from Middle Persian in southwest Iran, subset of dialects in Fars Province or Xollari dialect and additionally, to present their transcription, pronunciation, meaning and equivalent in Persian. Also, before dealing with the subject, a summary description about Xollar dialect has been provided for the eager reader. This study is based on field studies, interview, questionnaire, library compilation as well as analysis an

Influence of Two Preparation Techniques on Transportation of Simulated Type II Root Canals

Introduction: The purpose of this study was to evaluate the changes of canal configuration in simulated type II root canals that were instrumented by two different techniques using ProTaper Universal rotary files. Methods and Materials: Sixty simulated type II root canal in resin blocks were made and randomly divided into two groups. Pre and post-instrumentation images of resin blocks were prepared using stereomicroscope from three surfaces of blocks included two longitudinal section (mesiodistally and buccolingually), and one cross sectional surface. In the first group (G1) the straight canal was instrumented to the working length and the other canal was instrumented up to the area of canals junction. In second group (G2) both canals were instrumented to working length. The superimposed pre and post instrumentation images were assessed by the Adobe Photoshop software. The degree of transportation, centering ability, perimeter, surface and aspetic ratio (AR) in cross section and longitudinal section at apex, 3 mm and 5 mm above the apex, were measured. SPSS software, t-test and Mann-Whitney test were used for statistics analysis. Result: In mesiodistal direction, canal transportation was more (P=0.024) only in junction point in G2 which both canals were instrumented to working length. Also, surface changes were more significant (P=0.02) in G2 in cross sectional direction. The other parameter and also apical transportation had not significant difference in two groups. Conclusion: According to the results of this study, it can be concluded that both two preparation methods of type II canals can be used by rotary instruments.Keywords: Apical Transportation; Canal Transportation; Nickel Titanium; Root Canal Preparation; Root Canal Shap

An Analysis of the Link between Metacognitive Beliefs and Academic Health-oriented Lifestyle Preventive Behaviours Mediated by Self-efficacy during the COVID-19 Pandemic

[EN] The outbreak of the coronavirus and its ramifications, including lockdown and shutting down of many learning centers magnified the necessity of turning to virtual learning, has given rise to concerns about students learning and their reaction to the new teaching methods and the challenges they entail. The present study attempts to examine the link between metacognitive beliefs and behaviors that prevent health-oriented lifestyles through academic self-efficacy during the COVID-19 pandemic. The statistical sample consisted of 239 randomly selected undergraduate students of engineering at Azad University of Shahre-e Rey in the second semester of 1399-1400. The data were gathered using academic health-oriented life style test Salehzadeh et al. (2018) Academic Self-Efficacy Beliefs Questionnaire (ASEBQ), and Wells Metacognition Questionnaire-30 (MCQ-30). Findings of the study indicated that metacognitive beliefs are related to behaviors preventing academic health-oriented life style factors, such as learned helplessness and effort withdrawal, through self-efficacy. It is suggested that, According to the positive relationship that exists between metacognitive strategies and academic achievement. As well as these strategies are scalability learners need to be trained in skills such as self-regulation self- monitoring planning and goal setting. Until they dominate decided cognitive strategies and professors can also encourage students to use orientation by designing assignments, teaching study strategies, and using new teaching methods.Moradi, F.; Aghaei Sabet, S.; Soufi, S.
