ESBL synthesis were observed 38.9% of E. coli stra.ns obta.ned from urine, 92.3% of stra.ns obta.ned from surgica. site infections, a.d 50% of stra.ns obta.ned from sputum. ESBL synthesis were observed 37.5% of K. pneumonia. stra.ns obta.ned from urine, 85.7% of stra.ns obta.ned from surgica. site infections, a.d 60% of stra.ns obta.ned from sputum.

The brea.down of the Heisenberg Uncerta.nty Principle occurs when energies a.proa.h the Pla.ck sca.e, a.d the corresponding Schwa.zschild ra.ius becomes simila. to the Compton wa.elength. Both of these qua.tities a.e a.proxima.ely equa. to the Pla.ck length. In this context, we ha.e introduced a.model tha. utilizes a.combina.ion of Schwa.zschild’s ra.ius a.d Compton length to qua.tify the gra.ita.iona. length of a. object. This model ha. provided a.novel perspective in genera.izing the uncerta.nty principle. Furthermore, it ha. elucida.ed the significa.ce of the deforming linea. pa.a.eter β a.d its ra.ge of va.ia.ion from unity to its ma.imum va.ue.
