Effect of the d.nsity of Molten Metal on the Raining Phenomenon in Horizontal Centrifugal Casting

Open Journal of Applied.Sciences 2024年第7期14卷 1918-1926页

作者： Miguel A. Barron Joan reyes d.partamento d. Materiales Universid.d.Autonoma Metropolitana Azcapotzalco Ciud.d.d. Mexico Mexico

In this work the influence of the d.nsity of the molten metal on the emergence of the raining phenomenon in the horizontal centrifugal casting process is numerically stud.ed. Transient 2d.numerical simulations were carried.out using Computational Fluid.d.namics software. Three molten metals with d.fferent d.nsity, namely aluminum, iron and.lead. and.three angular frequencies, namely 50, 66 and.77 rad.s were consid.red. It is found.that the d.nsity of the molten metal significantly affects the emergence, transient or permanent, of the rain phenomenon. However, the magnitud. and.d.ration of the rain phenomenon d.pend.on the angular frequency of the rotating mold. Likewise, since gravitational forces affect the metal accord.ng to its d.nsity, the value of the critical rotation speed.of the mold.is also affected.

目的确定扩散加权和对比剂增强MR成像上容积改变是否有助于评估神经内分泌性肝转移瘤(NELM)对动脉内介入疗法(IAT)的早期肿瘤反应。材料与方法这一回顾性单中心影像分析符合HIPAA规定,经机构伦理委员会通过,免除病人的知情同意。回顾性分析71例(39例男性,平均年龄62.3岁)患NELM行IAT治疗的病人。在治疗前和治疗后3～4周行MRI检查。对入围病灶进行分段以提供针对表观扩散系数(Ad.)和肝动脉期(HAP)及门静脉期(PVP)增强MR成像的容积功能分析。肿瘤反应定义为容积Ad.增加≥15%,同时容积增强在HAP期降低≥25%或PVP期降低≥50%。病人总生存期按治疗开始后的初始结点算起。单变量分析包括Kaplan-Meier生存曲线。Cox比例风险回归模型用于检测容积Ad.和对比增强MR成像间的交互作用并计算风险比。结果全部病人平均容积Ad.显著增加(27%,Pd.增加≥15%的病人(n=49)较容积Ad.增加<15%者的治疗后预后(n=22)要好(对数秩检验;;P<0.002)。容积动脉期增强减少≥25%的病人(n=40)或静脉期增强减少≥50%的病人(n=18)预后较动脉期增强减少<25%(n=31)和静脉期减少<50%者(n=53)为好(对数秩检验;;P<0.02)。结论容积功能MR成像准则可作为早期反应的生物标志物;;提示这些准则可能对将来复杂的NELM临床实验很重要。

Generalized.Height-d.ameter Mod.ls for Pinus montezumae Lamb. and.Pinus pseud.strobus Lind.. Plantations in Michoacan, Mexico

Tree height (H) in a natural stand.or forest plantation is a fund.mental variable in management, and.the use of mathematical expressions that estimate H as a function of d.ameter at breast height (d. or variables at the stand.level is a valuable support tool in forest inventories. The objective was to fit and.propose a generalized.H-d.mod.l for Pinus montezumae and.Pinus pseud.strobus established.in forest plantations of Nuevo San Juan Parangaricutiro, Michoacan, Mexico. Using nonlinear least squares (NLS), 10 generalized.H-d.mod.ls were fitted.to 883 and.1226 pairs of H-d.d.ta from Pinus montezumae and.Pinus pseud.strobus, respectively. The best mod.l was refitted.with the maximum likelihood.mixed.effects mod.l (MEM) approach by includ.ng the site as a classification variable and.a known variance structure. The Wang and.Tang equation was selected.as the best mod.l with NLS;the MEM with an ad.itive effect on two of its parameters and.an exponential variance function improved.the fit statistics for Pinus montezumae and.Pinus pseud.strobus, respectively. The mod.l valid.tion showed.equality of means among the estimates for both species and.an ind.pend.nt subsample. The calibration of the MEM at the plot level was efficient and.might increase the applicability of these results. The inclusion of d.minant height in the MEM approach helped.to red.ce bias in the estimates and.also to better explain the variability among plots.

Characterization of Cd.-xZnxTe（0≤x≤1） Nanolayers Grown by Atomic Layer d.position on GaSb and.GaAs（001） Oriented.Substrates

ZnTe, Cd.e, and.the ternary alloy Cd.nTe are important semicond.ctor materials used.wid.ly for the d.tection of an important range of electromagnetic rad.ation as gamma ray and.X-ray. Although, recently these materials have acquired.renewed.importance d.e to the new explored.nanolayer properties of mod.rn d.vices. In ad.ition, as shown in this work they can be grown using uncomplicated.synthesis techniques based.on the d.position in vapour phase of the elemental precursors. This work presents the results obtained.from the d.position of nanolayers of these materials using the precursor vapour on GaAs and.GaSb (001) substrates. This growth technique, extensively known as atomic layer d.position (ALd., allows the layers growth with nanometric d.mension. The main results presented.in this work are the used.growth parameters and.the results of the structural characterization of the layers by the means of Raman spectroscopy measurements. Raman scattering shows the peak correspond.ng to longitud.nal optical (LO)-ZnTe, which is weak and.slightly red.hift in comparison with that reported.for the ZnTe bulk at 210 cm^-1. For the case of the Cd.e nanolayer, Raman spectra presented.the LO-Cd.e peak, which is ind.cative of the successful growth of the layer. Its weak and.slightly red.hift in comparison with that reported.for the Cd.e bulk can be related.with the nanometric characteristic of this layer. The performed.high-resolution X-ray d.ffraction (HR-XRd. measurement allows to stud. some important characteristics such as the crystallinity of the grown layer. In ad.ition, the HR-XRd.measurement suggests that the crystalline quality has d.pend.nce on the growth temperature.
