CP conservation and violation in neutral kaon decay are considered from a first principles’ theory, recently published as “Scalar Strong Interaction Hadron Theory”. The arbitrary phase angle relating K0 and 0 in current phenomenology is identified to be related to the product of the relative energy to the relative time between the s and d quarks in these kaons. The argument of the CP violating parameter ? is predicted to be 45? without employing measured data. The K0S decay rate is twice the K0L -K0S masss difference, in near agreement with data, and both are proportional to the square of the relative energy 29.44 eV. Any pion from K0L decay will also have a mass shift of ≈1.28 × 10-5 eV. The present first principles’ theory is consistent with CP conservation. To achieve CP violation, the relative time cannot extend to both +∞ and -∞ but is bounded in at least one direction. The values of these bounds lie outside the present theory and it is unknown how they can be brought forth. -b0 mixing is also considered and the relative energy is 663.66 eV.

From the equations of motion for baryons in the scalar strong interaction hadron theory (SSI), two coupled third order radial wave equations for baryon doublets have been derived and published in 1994. These equations are solved numerically here, using quark masses obtained from meson spectra and the masses of the neutron, ?0 and ?0 as input. Confined wave functions dependent upon the quark-diquark distance as well as the values of the four integration constants entering the quark-diquark interaction potential are found approximately. These approximative, zeroth order results are employed in a first order perturbational treatment of the equations of motion for baryons in SSI for free neutron decay. The predicted magnitude of neutron’s half life agrees with data. If the only free parameter is adjusted to produce the known A asymmetry coefficient, the predicted b asymmetry agrees well with data and vice versa. It is pointed out that angular momentum is not conserved in free neutron decay and that the weak coupling constant is detached from the much stronger fine structure constant of electromagnetic coupling.

One of the most unique properties of two-dimensional carbides and nitrides of transition metals(MXenes)is their excellent water dispersibility and yet possessing superior electrical conductivity but their industrial-scale application is limited by their costly chemical synthesis *** this work,the niche feature of MXenes was capitalized in the packed-bed electrochemical reactor to produce MXenes at an unprecedented reaction rate and yield with minimal chemical waste.A simple NH4F solution was employed as the green electrolyte,which could be used repeatedly without any loss in its ***,both fluoride and ammonium were found to play critical roles in the electrochemical etching,functionalization,and expansion of the layered parent materials(MAXs)through which the liberation of ammonia gas was *** electrochemically produced MXenes with excellent conductivity,applied as supercapacitor electrodes,could deliver an ultrahigh volumetric capacity(1408 F cm^(−3))and a volumetric energy density(75.8 Wh L^(−1)).This revolutionary green,energy-efficient,and scalable electrochemical route will not only pave the way for industrial-scale production of MXenes but also open up a myriad of versatile electrochemical modifications for improved functional MXenes.

Mulliken, NPA, MK and CHelpG population analyses have been accomplished at the level of MP2/6-31G（d,p） for the title system. The variations of four kinds of charges on NH3 with intermolecular distance infer that electron transfers from NH3 to H2O. MK and CHelpG population analyses indicate more electron transfer than Mulliken and NPA ones. The atomic charges resulted from MK and CHelpG schemes infer that electron transfers from N in NH3 to H in H2O, which confirms that this bimolecular complex possesses linear structure as H3N…hoh.

【目的】研究氧化苦参碱(oxymatrine,Oxy)对小鼠哮喘肺组织中转化生长因子β1(transforming growth factor-β1,TGF-β1)、血管紧张素II(angiotensinII,AngII)表达变化的影响。【方法】选用6～8周龄bALb/c小鼠50只,随机分为哮喘组(A),地塞米松治疗组(b),氧化苦参碱20mg/kg组(C)、40mg/kg组(D)、80mg/kg组(E)干预治疗各组10只。采用卵白蛋白(ovalbumin,OVA)加氢氧化铝[AI(OH)3]佐剂致敏的方法制备小鼠哮喘模,HE染色观察肺织病理形态学改变,免疫组化法检测肺组织中TGF-β1、AngII的表达变化。【结果】HE染色显示,A组肺组织出现明显的炎症反应,其他各组干预治疗后气道炎症反应均轻于A组。A组肺组织中TGF-β1、AngII可见较多阳性表达,b组地塞米松干预后阳性表达明显降低(P<0.01)。氧化苦参碱干预治疗后,C组、D组、E组的TGF-β1、AngII阳性表达均较A组降低(P<0.01),氧化苦参碱40和80mg/kg组肺组织中TGF-β1、AngII表达减少更显著,C与D,E比较差异有统计学意义(P<0.05)。【结论】氧化苦参碱能减轻哮喘气道炎症,并可抑制哮喘气道TGF-β1、AngII的表达,在哮喘治疗中有良好的作用。
