it is shown that there are exactly seventy-eight 3-generator 2-groups of order $2^{11}$ with trivial schur multiplier. we then give 3-generator, 3-relation presentations for forty-eight of them proving that these groups have deficiency zero.
feldspar grains, as a significant provenance indicator, of two terrigenous formations from central iran, the upper red formation, and moghan area, zivah formation, are used for provenance determination and the study of transportation and depositional history. the upper red formation (urf) is volumetrically the most important siliciclastic unit of the central iran and zivah formation (zf) repres...
in the urumieh-dokhtar volcanic zone, there are nearly parallel faults to the zagros zone.they were formed during collision of the arabic plate with central iran plate. the northwest-southeast trending of qom-zefreh fault system has long been recognized as major faults in central iran. the general aim of this research is to identify the activity period of this fault and the extent of its effect...
CASE SERIES SUMMARY This case series discusses novel characteristics identified in two cases of cowpox. One presented with upper airway signs, and was identified to have a focal laryngeal lesion. The other had central neurological signs at the terminal stages, with intracytoplasmic inclusion bodies identified within the cerebral hemispheres on histopathology. RELEVANCE AND NOVEL INFORMATION C...
abstract: the present study is an attempt to find out cultural exophoric references in iranian high-school elt textbooks and touch stone series to compare the frequency of occurrence of such references in these books. the purpose is to find out which of the series of the books under investigation impose a greater referential burden on efl learners as far as their reading comprehension of the ...
This study attempts to investigate the origin of red pigments, time of reddening, and processes responsible for red colouring of the Upper Miocene age Upper Red Formation, the most important clastic unit in central Iran. Mineralogical composition and textural properties of the studied sequences show that the Upper Red Formation sequences were not red when deposited, although some parts of red p...
We obtain, using the Birman-Schwinger method, a series of necessary conditions for the existence of at least one bound state applicable to arbitrary central potentials in the context of nonrelativistic quantum mechanics. These conditions yield a monotonic series of lower limits on the “critical” value of the strength of the potential (for which a first bound state appears) which converges to th...
