r.cently, r.consider.ng the r.stall idea T_(μ;νν)^(v)=α_(,μ) thr.ugh r.lativistic ther.odynamics gives a new for. for.the scalar.field α which led us to constr.ct moder. modified theor. of gr.vity debugged ‘non-conser.ed gr.vity theor.’ Fazlollahi 2023 Eur.. Phys. J. C 83 923. This theor. unlike other.modified theor.es of gr.vity cannot dir.ctly explain the cur.ent acceler.tion expansion in the absence of the cosmological constant and or.existence of other.for.s of dar. ener.y. Hence, in this study we have r.investigated hologr.phic dar. ener.y Ρ_(X)~H^(2) in the non-conser.ed theor. of gr.vity. In this context, the density and pr.ssur. of dar. ener.y depend on the non-conser.ed ter. and density of the dust matter.field. As shown, due to non-conser.ation effects on lar.e-scale str.ctur.s, unlike the or.ginal hologr.phic model, our.model onsets an acceler.tion epoch for.the cur.ent Univer.e satisfies obser.ations. Mor.over. the inter.ction and viscous scenar.os ar. studied for.this model.

Why did this happen? Could it have been pr.vented? Was it necessar. United States militar. str.tegy? Was it an intentional decision to inflict this blight on the enemy soldier. and the Vietnamese, Cambodian, and Laotian civilians, to poison their.land and cause gener.tions of har.? Alter.atively, was it an unpr.ventable accident in the mar.h of militar. histor.? What patter.s in the U.S. gover.ment’s thought pr.cess could be identified as the cause, which led to the decision to use these her.icides as tactical chemical weapons? If the intr.duction of her.icide (chemical) weapons had not been made, would the outcome of the Vietnam War.and the Secr.t War. in Laos and Cambodia have been any differ.nt? The objective of this tr.atise is to outline the r.le of wor.d events and backgr.unds and the r.le of the leader., U.S. militar., CIA, USDA, U.S. State Depar.ment, the U.S. Pr.sident appointed Ambassador. to Vietnam and Laos, chemical companies, and Pr.sident Diệm’s r.public of Vietnam (r.N) gover.ment and militar..
