the probability that the commutator of two group elements is equal to a given element has been introduced in literature few years ago. several authors have investigated this notion with methods of the representation theory and with combinatorial techniques. here we illustrate that a wider context may be considered and show some structural restrictions on the group.

conclusions sequence and structural diversity of the 3'utr variable region and poly u/uc region found in the local isolates indicate specificity in the regulating elements of 3'utr that might be associated with differential replication efficacy of the hcv pakistani isolates. the study necessitates functional characterization of these regulating elements to elucidate variable viral eff...

The present study identified the structural requirements for auditing educational and research processes in universities. The problem posed in this research is the lack of specific and appropriate structural dimensions for educational and research auditing. The study is descriptive and used the exploratory method. Questionnaires were used to collect data. Data analysis revealed that formalizati...

Interaction between a structure under base excitation and heavy non-structural elements that it supports is significant in the seismic analysis and design of the structure. Heavy non-structural elements may slide/rock under base excitation, and this dynamic action affects the seismic behavior of the supporting structure. Hence, in this study, a numerical model was presented to describe the seis...

the method of sampling unit was applied according to the importance of the park in urban landscape structure with the initial purpose of planning method to maximize environmental sustainability and recognizing the structural elements within the park. swot technique has been applied to analyze collected data and evaluate the strengths and weaknesses, opportunities and threats of affected areas. ...
