Students' anxiety about speaking English is significant to solve because it can affect their ability. This study aims measure the effectiveness of pair work activities on students’ and The researchers conducted quasi-experimental research in Palangka Raya academic year 2021/2022. In collecting data, a questionnaire test were used. population this eighth graders students one public junior high s...

Lecturers' abilities to use semiotic resources construct meaning and create engagement play an important role in university classrooms where English is the medium of instruction (EMI). The main focus this study on how EMI lecturers enrolled a professional development program interpersonal engage students through pair work activities. Two analyses were conducted dataset twelve micro-teaching ses...

in this paper the density and temperature dependencies of surface tension are investigated. using the lennard-jones (12,6), as an effective pair interaction potential, a linear expression is derived for isotherms of g /r2  versus r2 for some normal and chlorofluorocarbons (cfcs) fluids, where  is surface tension and r = 1/v is molar density. the linearity behavior of the derived equation is wel...

In this article, we consider pair frames in Banach spaces and   introduce Banach pair frames. Some various concepts in the frame theory such as frames, Schauder frames, Banach frames and atomic decompositions are considered as   special kinds of (Banach) pair frames.  Some frame-like inequalities  for (Banach)  pair frames are presented. The elements that participant  in the construction of (Ba...

in the present work, the integral equations method is used to calculate transport properties of polar fluids. for this goal, we use the stockmayer potential and examine theoretically the thermal conductivity of several refrigerant mixtures such as r125+r134a, r125+r32, r125+r152a, r134a+r32, r152a+r32, r134a+r143a, and r125+r143a. we solve numerically the ornstein-zernike (oz) equation using th...

Let (G;N) be a pair of groups. In this article, first we con-struct a relative central extension for the pair (G;N) such that specialtypes of covering pair of (G;N) are homomorphic image of it. Second, weshow that every perfect pair admits at least one covering pair. Finally,among extending some properties of perfect groups to perfect pairs, wecharacterize covering pairs of a perfect pair (G;N)...
