this thesis basically deals with the well-known notion of the bear-invariant of groups, which is the generalization of the schur multiplier of groups. in chapter two, section 2.1, we present an explicit formula for the bear-invariant of a direct product of cyclic groups with respect to nc, c>1. also in section 2.2, we caculate the baer-invatiant of a nilpotent product of cyclic groups wuth resp...
Theoretical framework: Sociolinguistics (Labov, Chafe, Biber, etc.) Conversation Analysis (Sacks, Schegloff, Jefferson, Wooffitt, etc.) Intonational Analysis (Pierrehumbert, Beckman, etc.) Diverse units in spontaneous speech: speech act idea unit information unit intonation unit, intonational phrase, tone group prosodic unit, prosodic phrase, prosodic group, prosodic utterance breath g...
In this paper we prove that each element of any regular Baer ring is a sum of two units if no factor ring of R is isomorphic to Z_2 and we characterize regular Baer rings with unit sum numbers $omega$ and $infty$. Then as an application, we discuss the unit sum number of some classes of group rings.
Background and objectives: Hospitalization in neonatal intensive care unit is a psychological crisis for the family. Reminiscence has positive effects on improving mental health. The aim of this study was to investigate the effect of reminiscence writing on distress tolerance and spiritual health of mothers with hospitalized newborns. Materials and Methods: This quasi-experimental study was pe...
the present study is an attempt to investigate the potential impact of inspirational quotes on improving english abstract vocabulary recall. to achieve this goal, a multiple choice language proficiency test of 60 items including vocabulary and grammar component was administered to a sample of 63 second-semester male and female students whose age ranged between 17 to 22 and they were studying en...

In the crystal of the title compound, C(21)H(15)ClNO(2) (+)·CF(3)SO(3) (-), adjacent cations are linked through C-H⋯π and π-π inter-actions [centroid-centroid distance = 3.987 (2) Å], and neighboring cations and anions via C-H⋯O and C-F⋯π inter-actions. The acridine ring system and benzene ring are oriented at a dihedral angle of 1.0 (1)° while the carboxyl group is twisted at an angle of 85.0 ...
The title salt, C(16)H(12)Cl(2)N(3) (+)·C(7)H(4)ClO(2) (-), features a non-planar cation, the dihedral angle between the quinolinium and benzene residues being 18.98 (10)°. The cation adopts an E conformation about the C-N bond, and the amine group is oriented towards the quinolinium residue. In the crystal, N-H⋯O hydrogen bonds link two cations with two anions, forming a 20-membered {⋯OCO⋯HNC(...
