Riemann surfaces with nodes can be described by introducing simple composite operators in matrix models. In the case of the Kontsevich model, it is sufficient to add the quadratic, but “non-propagating”, term (tr[X]) to the Lagrangian. The corresponding JenkinsStrebel differentials have pairwise identified simple poles. The result is in agreement with a conjecture formulated by Kontsevich and r...

A study on the contamination of ground water by industrial effluent in different areas Kala Shah Kaku has been conducted. is one Punjab. The major causes drinking such areas. Grounwater samples have analyzed for their characteristics. Standard laboratory techniques employed to determine various parameters from samples. mean values pH, Na+ , and SO4 2- are within permissible limits WHO standards...

where Ω ⊂ R2 is the image domain (a bounded open two-dimensional domain), g ∈ L∞(Ω) is the original image, that has to be segmented, K is a closed set of Hausdorff one-dimensional measure H1(K) and u ∈ C1(Ω \K). The set K is supposed to represent the edges of the segmented image u that is regular out of K and can be discontinuous across K (see Appendix A.2 for details). The actual minimization ...

this ethnography is a dialogic ethnography between field and two researchers. dialogic ethnography or dialogic anthropology was a result of textual revolution in discipline. textual or interpretive anthropology has been definition of culture as text founded in 1970s and 1980s. geertzian textual revolution considered and interpreted events and actions as texts. marcus, clifford, rabinow, crapanz...
