A series of new polyamides containing maleimide pendant group were prepared by low temperature polycondensation of 5-(4-(2,5-dioxo-2H-pyrrol-1(5H)-yl)benzamido)isophthaloyl chloride as a new monomer with various aromatic diamines in NMP. Monomer and polymers structures were identified through FT-IR, 1H-NMR and elemental analysis. Obtained polymers were soluble in polar solvents and non solu...

conclusion significant functional performance deficits were observed in the fai group in all tests except single hop test with greater deficits observed in the fai-gw group. hence, these tests can be used to determine the presence of fai. however no deficits were identified for the test involving sagittal plane functional activities suggesting that this test can not be used as a criterion to di...

introduction: the proportion of older adults in the population continues to grow in the developing countries. in addition, persons at or over the age of 60 years have decreased quality of life in geriartrics because of several factors, such as low physical activity and impairment in mobility. this study was performed to assess the effect of group-based exercise program on physical functional in...

objectives: the purpose of this study was to determine the functional mobility and balance in the elders after total hip arthroplasty in healthy coparison to elders. methods & materials: the current cross-sectional study was done on 20 patients (70.9±4.2) with hip osteoarthritis 6 months after total hip arthroplasty and 20 healthy subjects (73±5.7) as control group. patient group was assigned w...

In this paper we give a characterization for all semigroups whose square is a group. Moreover, we axiomatize such semigroups and study some relations between the class of these semigroups and Grouplikes,introduced by the author. Also, we observe that this paper characterizes and axiomatizes a class of Homogroups (semigroups containing an ideal subgroup).  Finally, several equivalent conditions ...
