Analysis of fish diversion efficiency and survivorship in the fish return system at San Onofre Nuclear Generating Station

This study examined the efficiency of fish diversion and survivorship of diverted fishes in the San Onofre Nuclear Generating Station Fish Return System in 1984 and 1985. Generally, fishes were diverted back to the ocean with high frequency, particularly in 1984. Most species were diverted at rates of 80% or more. Over 90% of the most abundant species, Engraulis mordax, were diverted. The system worked particularly well for strong-swimming forms such as Paralobrax clothratus, Atherinopsis californiensis, and Xenistius californiensis, and did not appreciably divert weaker-swimming species such as Porichthys notatus, Heterostichus rostratus, and Syngnathus sp. Return rates of some species were not as high in 1985 as in 1984. Individuals of most tested species survived both transit through the fish return system and 96 hours in a holding net. Some species, such as E. mordox, X. californiensis, and Umbrina roncador, experienced tittle or no mortality. Survivorship of Seriphus politus was highly variable and no Anchoa delicatissima survived. (PDF file contains 22 pages.)

Experiments in Neutrino Mass and Mixing: Part I - New Limits on Heavy Neutrino Emission in Nuclear Beta Decay. Part II - Fast Neutron Backgrounds for the San Onofre Neutrino Detector

In Part I of this thesis, a new magnetic spectrometer experiment which measured the β spectrum of ^(35)S is described. New limits on heavy neutrino emission in nuclear β decay were set, for a heavy neutrino mass range between 12 and 22 keV. In particular, this measurement rejects the hypothesis that a 17 keV neutrino is emitted, with sin^2 θ = 0.0085, at the 6δ statistical level. In addition, an auxiliary experiment was performed, in which an artificial kink was induced in the β spectrum by means of an absorber foil which masked a fraction of the source area. In this measurement, the sensitivity of the magnetic spectrometer to the spectral features of heavy neutrino emission was demonstrated.

In Part II, a measurement of the neutron spallation yield and multiplicity by the Cosmic-ray Underground Background Experiment is described. The production of fast neutrons by muons was investigated at an underground depth of 20 meters water equivalent, with a 200 liter detector filled with 0.09% Gd-loaded liquid scintillator. We measured a neutron production yield of (3.4 ± 0.7) x 10^(-5) neutrons per muon-g/cm^2, in agreement with other experiments. A single-to-double neutron multiplicity ratio of 4:1 was observed. In addition, stopped π^+ decays to µ^+ and then e^+ were observed as was the associated production of pions and neutrons, by the muon spallation interaction. It was seen that practically all of the π^+ produced by muons were also accompanied by at least one neutron. These measurements serve as the basis for neutron background estimates for the San Onofre neutrino detector.

[A_Ribera_SanEsteban] Modelo virtual de la iglesia de San Esteban de Ribera de Valderejo (Álava)

[ES] Ribera es un pueblo abandonado dentro del parque natural de Valderejo, el único edificio que queda en pie es la antigua iglesia. La razón por la que este edificio no fue derribado es la presencia de un conjunto de pinturas murales de época medieval. Por lo demás, el edificio (de unos 25 x 12 metros en planta) se encontraba en un mal estado de conservación (de hecho, un par de años más tarde de la realización de este trabajo se derrumbó la sacristía).

PMMA/SAN共混物薄膜表面相分离动力学的原位AFM研究

本论文主要借助原子力显微镜（AFM）、X-射线光电子能谱（XPS）等实验手段，纳米尺度上在线原位地研究了高温临界组成PMMMA/SAN（50／50，w／w）共混薄膜体系，分析并探讨了此共混薄膜表面相分离及其超薄膜体系的润湿／去润湿和相分离行为。首先，从敲击式AFM中相位图的成像原理出发，建立了一个高温下用原位AFM定性鉴别不同聚合物的纳米尺寸微区的方法，即：先在基底（硅）上铺展一层非常平坦的单一组分（SAN）薄膜，再在此千膜上，通过旋涂由选择性溶剂（冰醋酸）配制的另一组分（PMMA）的极稀溶液，使之不能形成一层连续的完整膜，最后在高温（175℃）下用敲击模式的原子力显微镜（TM-AFM）检测相位图随退火时间的变化。得到在175℃的相位图中，PMMA富相比SAN的富相显得更暗，这为后续工作提供了定性鉴别相区的方法。其次，高温下用原位AFM研究了PMMA/SAN薄膜表面相分离过程，在线观察了相分离的归并过程，定量地得到了临界相分离温度，并给出了特征波矢对时间依赖关系的标度指数，划分了相分离动力学演变的不同阶段。对于膜厚约为130nm的体系，表面相分离的临界温度大约为165℃，其表面相分离的特征波矢与时间的标度关系q+（t）-t-n，在整个实验时间内，随时间的演变过程中，显示了两个不同的指数变化区，即前期很慢的n=0.13和后期的n＝1／3。0.13的指数关系可能是由于表面聚合物链的几何受限及表面富集相把部分新生成的另一相覆盖所致，1／3的指数关系可以认为是由普遍的Brownian扩散所致。而对于膜厚为50曲的此组成共混薄膜，得到的标度关系与C汕n线性理论吻合得非常好的Spinodal Deposition（SD）表面相分离的初期，即n＝0，这是由于降低膜厚 增加了共混物的相容性，提高了临界温度，从而减缓了相分离过程，使得在我 们观测的时间范围内更易观察到表面相分离的初期。再次，用阶梯式降温的好M和XPS，发现了PMMA/SAN体系原位和离位实验结果存在巨大差别的主要原因之一—润湿温度的存在。对PMMA/SAN（50／50，w／w，-130nm）共混薄膜体系，原位AFM的退火和准淬火实验表明， 虽然在高温和室温、真空和常态、原位和离位，相分离的聚合物共混薄膜表面 形貌变化不大，但是表面物理性质却有很大的区别。原位XPS实验表明，未经 任何处理的样品在185℃退火时，很快在离表面很薄的下面形成一层PMMA含 量远低于本体值的薄层，之后最表面的PMMA也往本体迁移，直至表面SAN 的含量远高于它的本体值。对已在175℃退火20hr的此样品，逐渐降温退火过 程的原位XPS表明，当退火温度降至145oC时，样品表面几乎完全被PMMA覆盖，很好地验证了Conlposto等提出的润湿温度的假设，即对此体系，润湿温 度是原位和离位存在巨大的差异的主要因素之一，这与原位AFM的实验结果也，存在很好的一致性。最后，高温下原位观察了硅基底上PMMA/SAN超薄膜（膜厚-Rg）的去润湿、相分离过程和PMMA在基底上的润湿过程，以及云母基底上的该体系高温下的稳定润湿行为。以硅为基底的PMM刀sAN共混超薄膜在155”c下发生了类 似sPinodal dewetting的去润湿，其原因可能是在垂直于基底的浓度梯度引起的表面组成的涨落，对这种去润湿的动力学还进行了探讨。以硅为基底的PMMA/SAN共混超薄膜在175℃下不仅发生了类似spinodal dewetting的去润 湿，而且还发生了去润湿液滴内部的相分离以及相分离析出的PMMA润湿硅基底的过程，提出了一个简单的模型描述了这种复杂的过程。此外，还研究了不同基底对此共混超薄膜体系的润湿行为进行了研究，以云母为基底的此共混体系在175℃下长时间内是稳定的，其原因可能是云母与PMMA和SAN均有很强的作用力，足于补偿聚合物链在构象嫡上的损失。

Investigation of Degradation Behavior of Polymer on Surface of Film Due to the Existence of Monochromatic X-ray

Degradation and its temperature dependence of poly(methyl methacrylate) (PMMA) in the blend film of PMMA/SAN were investigated via ire-situ X-ray photoelectron spectroscopy(XPS). The results show that thermal degradation of PMMA takes place at 185, 130, 80 degrees C and even room temperature due to the existence of monochromatic X-ray. Furthermore, the degradation rate depends crucially on the experiment temperature.

Surface phase separations of PMMA/SAN blends investigated by atomic force microscopy

The thin films of poly(methyl methacrylate) (PMMA), poly(styrene-co-acrylonitrile) (SAN) and their blends were prepared by means of spin-coating their corresponding solutions onto silicon wafers, followed by being annealed at different temperatures. The surface phase separations of PMMA/SAN blends were characterized by virtue of atomic force microscopy (AFM). By comparing the tapping mode AFM (TM-AFM) phase images of the pure components and their blends, surface phase separation mechanisms of the blends could be identified as the nucleation and growth mechanism or the spinodal decomposition mechanism. Therefore, the phase diagram of the PMMA/SAN system could be obtained by means of TM-AFM. Contact mode AFM was also used to study the surface morphologies of all the samples and the phase separations of the blends occurred by the spinodal decomposition mechanism could be ascertained. Moreover, X-ray photoelectron spectroscopy was used to characterize the chemical compositions on the surfaces of the samples and the miscibility principle of the PMMA/SAN system was discussed.
