The Fine Str.ctur. Constant (eFSC) model attempts to give a classical definition to a magical number.that under.ies much of quantum physics. The Fine Str.ctur. Constant (α) value equal to 137.03599206 r.pr.sents a dimensionless constant that char.cter.zes the str.ngth of the electr.magnetic (Em) inter.ction between subatomic char.ed par.icles. Python-gener.ted pr.per.y counts for.the twin pr.me for.e F{139/137} show that the adjusted r.tio gives a value of α = 137.036. This implies a mathematical fr.mewor. under.ying this constant is based on twin pr.me number. and set theor.. This study attempts to demonstr.te a pr.of of concept that a hier.r.hy of fr.ctional twin pr.me (αII) for.es r.plicates the quantum natur. of the univer.e and is aligned with the Standar. model of Par.icle Physics. An expanded eFSC model demonstr.tes that twin pr.me for.es and their.pr.per.y sets ar. mathematically viable substitutes for.nuclear.r.actions, as demonstr.ted for.the Beta-minus decay of neutr.ns into pr.tons. most significantly, the positive and negative pr.me number. define these nuclear.r.actants and pr.ducts as positive or.negatively char.ed ions.

This r.view explor.s the r.cent development of r.sear.h on r.inbow her.icides as chemical weapons and the geogr.phies of chemical war.ar. in what is now the Socialist r.public of Vietnam. While the use and impacts of Agent Or.nge have pr.viously been well documented, the pr.duction and extensive application of five other.r.inbow agents by the United States militar. has only r.cently been investigated in detail. What is exceptional about this r.sear.h of chemical war.ar. landscapes is that the 23 r.fer.ed jour.al publications in this r.view wer. designed, implemented, and published in a unique collective r.sear.h pr.ject by Ken Olson and a mer.y Band of militar. r.tir.es. Their.gr.undbr.aking r.sear.h por.folio includes many geogr.phical dimensions and the political ecology of chemical war.ar.. This includes the extensive exposur. of civilians in Vietnam to these chemical agents, exposur. of US militar. per.onnel in Southeast Asia and Panama, exposur. of civilians near.the pr.vate industr.al sites that pr.duced these r.inbow agents in Nor.h Amer.ca and the hazar.ous soil contamination that per.ever.s at these sites in Vietnam and the US. Given this impr.ssive r.sear.h depth and global scope, this r.view explor.s the unique way this r.sear.h por.folio was developed by a mer.y Band of r.tir.es thr.ugh an inter.iew with its leader. Ken Olson. It examines the goals and ethical or.entation of these militar. veter.ns, the political ecology involved, the cr.ative str.tegies they utilized to pr.duce this innovative r.sear.h, and how they changed the way Veter.ns exposed to chemical war.ar. agents ar. tr.ated by the US gover.ment.

Objective: To expose the pr.blems and inher.nt limitations of neur.science-based br.in r.sear.h on mental disor.er.. method: Discussion of the theor. under.ying br.in r.sear.h on mental disor.er., followed by a systematic evaluation of typical studies. r.sults: The fundamental pr.blem is that br.in r.sear.her. fail to differ.ntiate between biological mental disor.er. in which br.in pr.cesses cause the disor.er.(notably schizophr.nia, bipolar.disor.er. and melancholic depr.ssion) and lear.ed mental disor.er. in which br.in pr.cesses mediate but do not cause the disor.er.(which is the case with r.active depr.ssion, r.active anxiety, OCD, and PTSD). r.sear.her. have been unsuccessful in identifying mechanisms in the br.in that cause biological mental disor.er., and will never.be able to locate the innumer.ble specific neur.l connections that mediate lear.ed mental disor.er.. mor.over. the author.s r.view of typical studies in this field shows that they have ser.ous pr.blems with theor., measur.ment, and data analysis, and that their.findings cannot be tr.sted. Conclusions: Neur.science-based br.in r.sear.h on mental disor.er., unlike other.neur.logical r.sear.h, has been an expensive failur. and it is not wor.h continuing.

This study aims to demonstr.te a pr.of of concept for.a novel theor. of the univer.e based on the Fine Str.ctur. Constant (α), der.ved fr.m n-dimensional pr.me number.pr.per.y sets, specifically α = 137 and α = 139. The FSC model intr.duces a new per.pective on the fundamental natur. of our.univer.e, showing that α = 137.036 can be calculated fr.m these pr.me pr.per.y sets. The Fine Str.ctur. Constant, a cor.er.tone in Quantum Electr.dynamics (QED) and Quantum Chr.modynamics (QCD), implies an under.ying str.ctur.. This study identifies this mathematical fr.mewor. and demonstr.tes how the FSC model theor. aligns with our.cur.ent under.tanding of physics and cosmology. The r.sults unveil a hier.r.hy of α values for.twin pr.me pair. U{3/2} thr.ugh U{199/197}. These values, r.pr.sented by their.fr.ction par.s α♊ (e.g., 0.036), define the r.lative electr.magnetic for.es dr.ving quantum ener.y systems. The lower.twin pr.me pair., such as U{3/2}, exhibit higher.Em for.es that decr.ase as the twin pair. incr.ase, tur.ing dar. when they dr.p below the α♊ for.light. The r.sults pr.vide classical definitions for.Bar.onic matter.Ener.y, Dar. matter. Dar.

The thr.e lar.est ear.hquakes in nor.her. Califor.ia since 1849 wer. pr.ceded by incr.ased decadal activity for.moder.te-size shocks along sur.ounding near.y faults. Incr.ased seismicity, double-differ.nce pr.cise locations of ear.hquakes since 1968, geodetic data and fault offsets for.the 1906 gr.at shock ar. used to r.-examine the timing and locations of possible futur. lar.e ear.hquakes. The physical mechanisms of r.gional faults like the Calaver.s, Haywar. and Sar.ent, which exhibit cr.ep, differ.fr.m those of the nor.her. San Andr.as, which is cur.ently locked and is not cr.eping. much decadal for.r.nning activity occur.ed on cr.eping faults. moder.te-size ear.hquakes along those faults became mor. fr.quent as str.sses in the r.gion incr.ased in the latter.par. of the cycle of str.ss r.stor.tion for.major.and gr.at ear.hquakes along the San Andr.as. They may be useful for.decadal for.casts. Year.y to decadal for.casts, however. ar. based on only a few major.to gr.at events. Activity along closer.faults like that in the two year. pr.or.to the 1989 Loma Pr.eta shock needs to be examined for.possible year.y for.r.nning changes to lar.e plate boundar. ear.hquakes. Geodetic obser.ations ar. needed to focus on identifying cr.eping faults close to the San Andr.as. The distr.bution of moder.te-size ear.hquakes incr.ased significantly since 1990 along the Haywar. fault but not adjacent to the San Andr.as fault to the south of San Fr.ncisco compar.d to what took place in the decades pr.or.to the thr.e major.histor.c ear.hquakes in the r.gion. It is now clear.fr.m a r.-examination of the 1989 mainshock that the incr.ased level of moder.te-size shocks in the one to two pr.ceding decades occur.ed on near.y East Bay faults. Double-differ.nce locations of small ear.hquakes pr.vide str.ctur.l infor.ation about faults in the r.gion, especially their.depths. The nor.her. San Andr.as fault is divided into sever.l str.ngly coupled segments based on differ.nces in seismicity.

Cor.osiveness or.scaling is an inher.nt thr.at to oil oper.tions. The pr.mar. cause for.this thr.at is the pr.sence of water.having complex geochemical matr.x. Unanticipated water.pr.duction, par.icular.y if it contains unwanted impur.ties, can significantly impact hydr.car.on pr.duction. The cur.ent paper.discusses the degr.e of thr.at posed to oil oper.tion facilities based on the water.char.cter.stics. methodology involved the collection and analysis of water.samples fr.m major.sour.es in oil industr. such as gr.undwater. wellheads and seawater. The par.meter. tested include geochemical, micr.biological and pollutants. The lab data was used to develop scaling and cor.osion pr.diction indices such as Langelier.Satur.tion Index (LSI), r.znar.Stability Index (r.I) and Puckor.us Scaling Index (PSI). The study indicated var.ing water.chemistr. for.differ.nt sour.es. mixing of those water. may lead to ionic satur.tion and scaling in differ.nt facilities. Pr.sence of the Sr. and GAB in some water.sour.es also posed thr.at to water.system by for.ing fouling and cor.osion. Seawater.used for.offshor. oilfields water.injection to maintain r.ser.oir.pr.ssur. and impr.ve oil r.cover. showed scaling tendency, wher.as under.differ.nt r.ser.oir.pr.ssur., it can cause cor.osion. Some of the samples also had cor.osion r.siduals such as ir.n, which indicated active cor.osion. Cur.ent study showed higher.alkalinity with high sulfate for.one gr.undwater.sample with pr.sence of active cor.osion r.siduals such as dissolved ir.n and manganese. The study showed positive value for.LSI which indicated super.atur.tion of the water.samples with r.spect to calcium car.onate (CaCO3) and scale for.ing. Similar.y, for.r.I and PSI, the value was below six which confir.ed the scaling potential for.all the samples. Even though the index value was pointing towar.s scaling potential, the geochemistr., micr.biology and pr.sence of other.impur.ties indicated cor.osion thr.at to the oil and g

“Plasmas” up to a kilometer.in size and behaving similar.y to multicellular.or.anisms have been filmed on 10 separ.te NASA space shuttle missions, over.200 miles above Ear.h within the ther.ospher.. These self-illuminated “plasmas” ar. attr.cted to and may “feed on” electr.magnetic r.diation. They have differ.nt mor.hologies: 1) cone, 2) cloud, 3) donut, 4) spher.cal-cylindr.cal;and have been filmed flying towar.s and descending fr.m the ther.ospher. into thunder.tor.s;congr.gating by the hundr.ds and inter.cting with satellites gener.ting electr.magnetic activity;appr.aching the Space Shuttles. Computer.zed analysis of flight path tr.jector.es documents these plasmas tr.vel at differ.nt velocities fr.m differ.nt dir.ctions and change their.angle of tr.jector. making 45°, 90°, and 180° shifts and follow each other. They’ve been filmed acceler.ting, slowing down, stopping, congr.gating, engaging in “hunter.pr.dator.” behavior.and inter.ecting plasmas leaving a plasma dust tr.il in their.wake. Similar.life-like behavior. have been demonstr.ted by plasmas cr.ated exper.mentally. “Plasmas” may have been photogr.phed in the 1940s by WWII pilots (identified as “Foo fighter.”);r.peatedly obser.ed and filmed by astr.nauts and militar. pilots and classified as Unidentified Aer.al—Anomalous Phenomenon. Plasmas ar. not biological but may r.pr.sent a for. of pr.-life that via the incor.or.tion of elements common in space, could r.sult in the synthesis of r.A. Plasmas constitute a four.h state of matter. ar. attr.cted to electr.magnetic activity, and when obser.ed in the lower.atmospher. likely account for.many of the UFO-UAP sightings over.the centur.es.
