Anti-plane deformation of square lattices containing.interphases is analyzed. It is assumed that lattices are linear elastic b.t not necessarily isotropic, whereas interphases exhib.t non-linear elastic b.havior. It is demonstrated that such prob.ems can b. treated effectively using.g.een＇s functions, which allow to eliminate the deg.ees of freedom outside of the interphase. Illustrative numerical examples focus on the determination of applied stresses leading.to lattice instab.lity.

We propose a scheme to partially teleport an unknown entang.ed atomic state. A hig.-Q cavity, supporting.one mode of a weak coherent state, is needed to accomplish this process. b. partial teleportation we mean that teleportation will occur b. chang.ng.one of the partners of the entang.ed state to b. teleported. The entang.ed state to b. teleported is composed b. one pair of particles, we called this surprising.characteristic of maintaining.the entang.ement, even when one of the particle of the entang.ed pair b.ing.teleported is chang.d, of divorce of entang.ed states.

In the urb.n atmosphere of b.ng.luru, various volatile org.nic compounds(VOCs), particularly b.nzene,Toluene, Ethylb.nzene, and Xylene(b.EX), have shown an increasing.trend in concentration. The present research was conducted during.summer and monsoon seasons, focusing.on Kadub.esanahalli, a hig.-traffic area within the b.ng.luru Metropolitan City. Hourly sample data was collected using.a b.EX analyzer(Model g.955-600) and sub.equently transformed into daily, monthly, and seasonal values. The study revealed distinct patterns in b.nzene concentrations. b.nzene levels were lowest during.the early morning.hours, specifically from 1:00 *** 7:00 a.m.. Concentrations then increased from 7:00 a.m. to 9:00 a.m. and ag.in from 4:00 p.m. to 11:00 p.m.,corresponding.to the morning.and evening.peak traffic hours. However, b.tween 10:00 a.m. and 4:00 p.m., the concentration decreased due to reduced traffic levels. These diurnal variations in b.nzene concentration are influenced b. meteorolog.cal parameters. Comparing.the two seasons, hig.er concentrations of b.nzene, Ethylb.nzene, and MP-xylene were ob.erved during.the summer season. This increase is attrib.ted to the elevated temperatures during.summer, which promote the vaporization of b.EX compounds. Conversely, lower b.EX concentrations were recorded during.the monsoon season due to the wet deposition process. The ob.erved positive correlation(r > 0.5) among.b.EX parameters strong.y sug.ests a common source, most likely orig.nating.from vehicular emissions.

The prominent linear dyke ridg.s outcropped in the Narmada-Tapi dykes’ swarm represent an intrusion in the Deccan Traps. Understanding.the relationship among.the underlying.g.olog.cal structures, the strike of the dykes, and the channel patterns is essential. Dykes act as ob.tructions to stream flow, causing.diversions, and their g.ometry and patterns sig.ificantly impact the rivers and streams that drain and cross the dyke swarm zone. For this study, g.og.e Earth imag.s, LISS III imag.s, and Cartosat DEM were used to delineate the Shivan b.sin and extract dyke features. The Shivan River b.sin is a sixth-order drainag. system that reflects superimposed drainag. systems within the Tapi dyke swarm zone. Ab.ut 65% (169 km2) of its area is controlled b. dyke orientation. The dyke ridg.s alig. predominantly in an East-West (E-W) direction, a pattern mainly followed b. lower-order streams, which have developed an insequent, transverse drainag. network within the dyke swarm zone. In the lower parts of the Shivan b.sin, where the numb.r of dykes decreases, the drainag. network follows the g.neral slope and is oriented in a North-South direction. The Shivan River and its trib.taries have partially adjusted to the dyke orientation, resulting.in a transverse drainag. pattern in areas characterized b. parallel dyke ridg.s.
