let $r$ be a ring and $m$ a right $r$-module with $s=end_r(m)$. a module $m$ is called semi-projective if for any epimorphism $f:mrightarrow n$, where $n$ is a submodule of $m$, and for any homomorphism $g: mrightarrow n$, there exists $h:mrightarrow m$ such that $fh=g$. in this paper, we study sgq-projective and$pi$-semi-projective modules as two generalizations of semi-projective modules. a m...

Background: Anopheles stephensi is considered to be the main malaria vector in the Middle East area including Iran. We aimed to evaluate the efficiency of a granule 10% formulation of Bacillus thuringiensis against this species under laboratory and semi-field conditions in an endemic malarious area of Iran. Method: After collecting mosquitos ...

A modified skyhook control for the semi-active Macpherson suspension system is considered. A new quarter-car model, which incorporates the rotational motion of the unsprung mass, is introduced. A feedback control law in the form of a modified skyhook control is derived. Two filters to estimate the absolute velocity of the sprung mass and the relative velocity of the rattle space are designed. B...

Mobile technologies and more precisely apps have disrupted technology scenario. Bring your own application (BYOA) is a new trend that has emerged after the “bring your own device” (BYOD) vogue. However, and in spite of its intrinsic benefits, the trend presents also several caveats and Enterprise app stores are seen as a way to tackle these risks. In this paper, authors present ModEAS, a system...

This study aimed to develop and validate an instrument to evaluate English language teachers’ lesson plan- ning self-concept. To this end, 30 English teachers were asked to prepare a sample lesson plan and 15 of them were invited to participate in a semi-structured interview. A tentative questionnaire including six fac- tors namely: classroom management, lesson planning conformity, planning eff...

Social reformers such as John Stuart Mill and John Dewey have long expressed concern about a tension between democratic principles and organizational practices that appear undemocratic.' More recently, a substantial body of academic literature advocating changes in organizations to make them more democratic has been produced.2 Change has been advocated on a variety of normative grounds. In a no...
