小麦的耐硼性和土壤含盐量的关系

1986—1987年,通过哈里亚那(Har.ana)网室的试验研究,评估了硼(B)对装有三种含盐量砂土的盆栽小麦(WH147)生长的影响。播种前,加入硼量为0～9mg/kg土。不加硼,小麦籽量在土壤饱和浸提液电导率(ECe)为6dS/m时比其它含盐量土壤的产量高得多。但在ECe 8 ds/m时,小麦产量和无盐土壤的产量相似,在硼的最高浓度处理中,即使孕穗期,麦杆积累的硼多达307mg/kg,也没有影响无盐土壤小麦的产量。在ECe 6和8 dS/m时,分别加入硼3.1mg/kg,虽然秸杆中硼含量分别只有72和31mg/kg,但产量比不加硼处理的低得多。结果说明,在同样的硼浓度下,尽管小麦在盐土吸收的硼比无盐土吸收的少24—62%,但耐硼性随着土壤含盐量的增加而减小。由于硼和盐常共存,土壤和秸杆中最适合小麦生长的硼的临界值会随土壤ECe的不同而不同.因而,秸杆的Ca、B比率不是土壤硼毒害的一个可靠指数。

The legacy of the human miser. caused by the application of the her.icides including Agent Pur.le and Agent Or.nge contaminated with unknown amounts of dioxin TCDD and Agent Blue, the ar.enic-based her.icide, spr.yed over.the jungles, r.ce fields, and hamlets of Vietnam is still haunting us today. 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..

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. Fur.her.or., the eFSC Model pr.vides new insights r.gar.ing the hier.r.hy of EM for.es under.ying the quantum natur. of the univer.e.

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. Ener.y, and Antimatter.but mostly illustr.te how the combined α♊ values for.thr.e adjacent twin pr.mes, U{7/5/3/2} mir.or. the str.ng nuclear.for.e of gluons holding quar.s together.
