The purpose of this note is to give an example to counter the result of [5] and to find the cardinality of the image of a fuzzy symmetric subgroups of S4, S5 and Sn. Mathematics Subject Classification: 03G10, 20B30, 20B35

stress-corrosion cracking (scc) tests were conducted in the near-neutral ph standard solution, ns4, and in an actual soil solution, using four-point bending at a high stress ratio and low frequency conditions very similar to those of operational pipelines. pitting incubation appeared first and then pitting initiated and grew in both solutions although there were many more pits on the specimen t...

the current research was carried out to find out the most effective environmental factors in plant species occurrence by classification and ordination methods. for this purpose, the study was conducted in nir rangelands of yazd province and topography, climate, soil and grazing intensity data of the region were determined. sampling method was randomized–systematic and within each sampling unit ...

the goal of this study was to survey the natural vegetation on waste landfills and suggest arestoration plan. in the study, i identified 63 families, 275 species, and 34 varieties of aboveground vascular flora. robinia pseudo-acacia was the dominant tree, with a basal area density of 1.51¡3/ha, followed in decreasing order by salix koreensis and populus sieboldii. twinspan resulted in the class...

OBJECTIVES Knee osteoarthritis (OA) is a leading cause of activity limitations. The knee OA population is likely to consist of subgroups. The aim of the present study was to identify homogeneous subgroups with distinct trajectories of activity limitations in patients with early symptomatic knee OA and to describe characteristics of these subgroups. METHODS Follow-up data over a period of 5 ye...

A fluorescence in situ hybridization (FISH) technique based on binding of a rhodamine-labelled oligonucleotide probe to 16S rRNA was used to estimate the numbers of ribosome-rich bacteria in soil samples. Such bacteria, which have high cellular rRNA contents, were assumed to be active (and growing) in the soil. Hybridization to an rRNA probe, EUB338, for the domain Bacteria was performed with a...
