Development on Glass Formulation for Aluminum Metal and Glass Fiber (2012)

원전에서 발생되는 방사성폐기물에 대한 고화처리 방법 중 하나인 유리화기술이 일부 가연성폐기물에 대해 적용되고 있다. 국내외적으로 중저준위 방사성폐기물의 효과적인 감용과 안정적인 처분을 위해 다양한 폐기물에 대한 유리화기술 적용방안이 확대 연구되고 있으며, 최근에는 가연성폐기물 뿐만 아니라 알루미늄 금속과 같은 비가연성폐기물에도 유리화 연구가 활발하게 진행되고 있다. 공기조화계통 (HVAC)에는 주로 필터가 이용되고 있으며, 사용 후 필터는 여과재 (유리섬유 및 알루미늄)를 이용하여 배기체를 흡착하기 때문에 방사성폐기물로 처리가 되어야 한다. 본 연구는 필터에 대한 처리기술 연구를 위해 유도가열식 저온용융로 (Cold Crucible Induction Melter: CCIM)를 이용한 유리화 타당성 연구를 수행하였다. 사용후 필터에 대한 유리화 (Vitrification)는 먼저 유리섬유 및 알루미늄 함량을 고려한 최적의 유리조성을 개발 하였으며, 개발된 유리 조성을 이용하여 최적의 폐기물 저감을 위한 용융변수와 최종 생성된 유리고화체의 특성을 분석하였다. 사용후 필터 유리화용 조성유리는 주로 <TEX>$SiO_2$</TEX>와 <TEX>$B_2O_3$</TEX>로 구성되어 있다. 전기로를 이용한 용융물 특성시험에서는 폐기물 투입률 및 최종 생성물인 유리고화체의 특성이 검토되었다. 본 연구에서는 알루미늄 금속과 유리섬유로 구성된 필터에 대한 유리조성 개발과 이를 통해 생성된 유리고화체의 물리화학적 특성을 검토하고 유리화 타당성을 확인하였다. Vitrification technology has been widely applied as one of effective processing methods for wastes generated in nuclear power plants. The advantage of vitrifying for low- and intermediate-level radioactive wastes has a large volume reduction and good durability for the final products. Recently, a filter using on HVAC(Heating Ventilating & Air Conditioning System) is composed with media (glass fiber) and separator (aluminum film) has been studied the proper treatment technology for meeting the waste disposal requirement. Present paper is a feasibility study for the filter vitrification that developing of the glass compositions for filter melting and melting test for physicochemical characteristic evaluation. The aluminum metal of film type is preparing with 0.5 cm size for proper mixing with glass frit, glass fiber is also preparing with 1 cm size within crucible. The glass compositions should be developed considering molten glass are related with wastes reduction. Glass compositions obtained from developing on glass formulation are mainly composed of <TEX>$SiO_2$</TEX> and <TEX>$B_2O_3$</TEX> for aluminum metal. A variety of factors obtained from the glass formulation and melting test are reviewed, which is feeding rate and glass characteristics of final products such as durability for implementing the wastes disposal requirement.

Sample Composition Changes in Sampling and Analysis of Organic Compounds in Aerosols (1979)

Abstract Effects of transportation and storage of air particulate filters on sample composition were investigated by GC and GC/MS analysis of 42-Hi-Vol filter samples taken in a large metropolitan city. One-half of the filters were transported and stored using paper envelopes while the others were individually wrapped in aluminum foil before transportation. One half of each filter received was extracted and analyzed immediately while the other half was stored in a refrigerator for later analysis. Significant losses of organic material from stored filters was observed for filters stored in paper envelopes and filters sealed in aluminum foil, although losses were less for filters wrapped in metal foil. There is some indication that metal foil may protect filters from external contamination after sampling. Key Words: Air particulatessample storagetrace organics.
Laser-induced vasorelaxation by intravascular transluminal approach (1996)

We have observed that precontracted vascular smooth muscle showed vasorelaxation by exposure to low power UV laser. We have reported that nitric oxide-like substance played an important role in the laser-mediated vasorelaxation. We investigated the photovasorelaxation with intravascular transluminal irradiation using in vivo model.A 2 Fr. catheter was inserted in the femoral artery of a rabbit under anesthesia. A 400 micron quartz fiber was inserted through the cathter. The inside femoral artery was irradiated through the fiber with a 8 mW He-Cd laser (325nm) during 30 seconds.The laser irradiation produced vasorelaxation (185% on the average) compared with mechanical vasorelaxation (l50% on the average) with angiography.This result shows that we might be able to release vasospasm by intravascular transluminal irradiation with low-power ultraviolet laser.
Detection of Delaminations by Ultrasonic Spectroscopy (1976)

A newly developed instrument for ultrasonic spectroscopy has been evaluated on various types of laminated structures to assess its effectiveness for detecting delaminations in composites. Presented are ultrasonic echo spectra obtained for different types of disbond conditions. In addition, a comparison of these spectra with computer- generated reflection data is made. Results show that in most of the cases examined the detectability of a disbond can be predetermined by computer analysis.
Amines: possible causative agents in the development of bronchial hyperreactivity in workers manufacturing polyurethanes from isocyanates. (1983)

Investigations of respiratory symptoms among workers in a factory producing polyurethane foam included measurement of air pollution with amines and isocyanates and a simultaneous health investigation of the exposed workers. An increased bronchial reactivity to inhaled methacholine was found in the study group compared with two unexposed control groups. This finding, together with visual disturbances in the exposed group, were assumed to be caused mainly by the volatile amines. The concentrations of isocyanates in air were well below 0.005 ppm. The amine concentration was 1000 to 10 000 times higher than the isocyanate concentration. The most volatile amine, N-methylmorpholine, occurred in the air in concentrations higher than 10 ppm. The results indicate that not only the isocyanates but also the amines might well be responsible for respiratory symptoms among exposed workers in polyurethane foam production.
A method to characterize the roughness of 2‐D line features: recrystallization boundaries (2016)

A method is presented, which allows quantification of the roughness of nonplanar boundaries of objects for which the neutral plane is not known. The method provides quantitative descriptions of both the local and global characteristics. How the method can be used to estimate the sizes of rough features and local curvatures is also presented. The potential of the method is illustrated by quantification of the roughness of two recrystallization boundaries in a pure Al specimen characterized by scanning electron microscopy.
The cellular oxygen tension regulates expression of the endoplasmic oxidoreductase ERO1‐Lα (2003)

The formation of disulfide bonds in the endoplasmic reticulum requires protein disulfide isomerase (PDI) and endoplasmic reticulum oxidoreductin 1 (ERO1) that reoxidizes PDI. We report here that the expression of the rat, mouse and human homologues of ERO1-Like protein alpha but not of the isoform ERO1-Lbeta are stimulated by hypoxia in rats vivo and in rat, mouse and human cell cultures. The temporal pattern of hypoxic ERO1-Lalpha induction is very similar to that of genes triggered by the hypoxia inducible transcription factor (HIF-1) and is characteristically mimicked by cobalt and by deferoxamine, but is absent in cells with a defective aryl hydrocarbon receptor translocator (ARNT, HIF-1beta). We speculate from these findings that the expression of ERO1-Lalpha is probably regulated via the HIF-pathway and thus belongs to the family of classic oxygen regulated genes. Activation of the unfolded protein response (UPR) by tunicamycin, on the other hand, strongly induced ERO1-Lbeta and more moderately ERO1-Lalpha expression. The expression of the two ERO1-L isoforms therefore appears to be differently regulated, in the way that ERO1-Lalpha expression is mainly controlled by the cellular oxygen tension, whilst ERO1-Lbeta is triggered mainly by UPR. The physiological meaning of the oxygen regulation of ERO1-Lalpha expression likely is to maintain the transfer rate of oxidizing equivalents to PDI in situations of an altered cellular redox state induced by changes of the cellular oxygen tension.

Continued cultivation is possible with KT3, KT30 and KT38 with NH3 as the source of nitrogen, and β-phenylpropionic acid for KT3 and KT38, γ-phenylbutylic acid for KT30 and δ-phenyl-n-valeric acid for KT30 and KT38 as the sole sources of carbon, respectively.
Abstract IA14: Targeting Ras (2017)

Abstract We are exploring multiple ways of targeting Ras proteins and Ras-driven cancers. We have identified compounds that covalently bind to cysteine-185 on K-Ras 4B, and to the G-domain of K-Ras 4A and 4B. We are also screening for compounds that bind directly to K-Ras using a new technique referred to as Second Harmonic Generation and are developing compounds that promote phosphorylation of K-Ras4B on serine-181. In addition, we are attempting to solve novel structures of oncogenic Ras proteins on their own, or complexed with effectors, regulators and chaperones, in an attempt to identify new targeting opportunities. For example, we have solved the structure of fully processed K-Ras 4B bound to PDE-delta. This co-structure suggests several new approaches to targeting K-Ras processing. In addition to targeting K-Ras directly, we are validating downstream dependencies that are specific for K-Ras cancers, including the cytokine LIF, which is expressed at high levels in K-Ras transformed cells and plays a major role in stem-like properties of K-Ras cancers. Suppressing LIF expression using shRNA, CRISPR or monoclonal antibodies has profound effects on K-Ras tumor initiation and maintenance, and suggests new therapeutic opportunities. We are also analyzing signaling pathways that differ between Ras mutants and between Ras isoforms. These results, and their opportunities for intervention, will be discussed.

Ultralightweight Cementing Technology Sets World Record for Liner Cementing With a 5.4 lbm/gal Slurry Density (2006)

Abstract In an effort to meet increased demand for petroleum products, operators are drilling in more challenging environments. In Mexico, meeting the new challenges is requiring more skills and innovative materials from oilwell cementing providers. Nowhere else in the world have service providers attempted cementing across more depleted zones or weaker formations. Current cementing technology may not ensure successful circulation and an effective seal, which can have a great impact on (1) the cost of drilling a well and (2) the productive life of the well. In addition to the easily quantified cost of often-required remedial work, additional costs that are more difficult to quantify can be incurred from delays in production delivery and early water production. Traditionally, the industry has relied on two very different technologies for the creation of ultra-light (densities &lt; 10 lb/gal) cement slurries. The current technology involves either (1) the creation of a foamed cement using nitrogen or (2) the addition of lightweight microspheres (LMS) (sg &lt; 1.1) into the cement. While both of these technologies are capable of producing very light cement slurries, neither of them has been used in an oil well to form an effective seal at densities below 7.3 lb/gal. In these most difficult Mexican formations where fracture gradients range from 7.3 down to 6 lb/gal, current cement densities of 7.3 lb/gal or greater have reduced chances of successful circulation. This paper presents case histories from Mexico showing how a melding of both of these technologies, foam and microspheres, were required to stretch current lower slurry-density limits, allowing us to meet extreme operational demands. Along with the case histories and laboratory data, guidelines are provided for the best use of these technologies at densities down to 5 lb/gal. Details provided from the case histories illustrate how the advantages of both technologies were maximized, while their limitations were minimized.
Oxygen diffusion through Yb2O 3 /YBa 2 Cu 3 0 7-δ bilayers (1994)

We have studied the rate of oxygen diffusion through ytterbium oxide (Yb<SUB>2</SUB>O$3), a buffer and dielectric layer used in high critical temperature superconducting (HTSC) structures. An epitaxial bilayer film of Yb<SUB>2</SUB>O<SUB>3</SUB> on YBa<SUB>2</SUB>Cu$3)O<SUB>7-(delta</SUB> ) (YBCO) was deposited onto an (001) oriented single crystal MgO substrate using the pulsed laser deposition technique. The rate of oxygen diffusion through the bilayer was investigated from 365 to 655 degree(s)C by post deposition annealing individual section of the bilayer in 0.5 atm of <SUP>18</SUP>O enriched molecular oxygen gas. Secondary ion mass spectroscopy was used to depth profile <SUP>18</SUP>O and <SUP>16</SUP>O in each sample. Oxygen diffusion coefficients for Yb<SUB>2</SUB>O<SUB>3</SUB> at 365, 465, 555 and 655 degree(s)C were determined to be roughly (6, 16, 360, and 200) X 10<SUP>-1</SUP>, respectively. For temperatures greater than about 500 degree(s)C, these diffusion rates can limit oxygen intake into underlying YBCO films; therefore, HTSC multilayer devices that utilize Yb<SUB>2</SUB>O<SUB>3</SUB> as a dielectric layer may require longer annealing cycles in order to fully oxygenate each underlying HTSC layer.
A PRAM oriented language (2002)

A new programming language oriented to the PRAM model is presented and results of its implementation on transputer networks are reported. During the last four years of teaching at the Computer Science Faculty of La Laguna University, the new language has proved to be a practical tool for the study, design, analysis and verification of PRAM algorithms. The theoretical analysis predicts the good performance of the implementation when the ratio between the number of read and write requests is large and when the size of the network is bounded. These asserts are supported by the computational results. The approach taken in the design of the language is a compromise between efficiency and simplicity.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Effects of Spaceflight on the Immune System (2018)

The immune system belongs to the most affected systems during spaceflight, and sensitivity of cells of the human immune system to reduced gravity has been confirmed in numerous studies in real and simulated microgravity. Immune system dysfunction during spaceflight represents a substantial risk for exploration class mission knowledge about the clinical, cellular, and genetic basis of immune system response, and adaptation to altered gravity will provide key information for appropriate risk management, efficient monitoring, and countermeasures against existing limiting factors for human health and performance during manned exploration of the solar system. In spite of the immune system dysregulation, studies indicate an adaptation reaction of the immune system to the new microgravity environment, at least for the T-cell system, starting after 2 weeks and continuing until 6 months or longer, reflected by cytokine concentrations in blood plasma or in stimulation assays. At the cellular level, rapid adaptation responses could be detected as early as after seconds until minutes in T cells and macrophages. Therefore, adaptive responses of cells and the whole organism could be expected under microgravity and altered gravity in general. Preventive countermeasures should therefore consider support and stabilization of the endogenous adaptation programs. Potential countermeasures for risk mitigation are summarized in this chapter. We assume that the immune systems not only have a significant adaptation potential when challenged with low gravitational environments but also provide interesting preventive and therapeutic options for long-term space missions.
Leukocyte Heterogeneity in Adipose Tissue, Including in Obesity (2020)

Adipose tissue (AT) plays a central role in both metabolic health and pathophysiology. Its expansion in obesity results in increased mortality and morbidity, with contributions to cardiovascular disease, diabetes mellitus, fatty liver disease, and cancer. Obesity prevalence is at an all-time high and is projected to be 50% in the United States by 2030. AT is home to a large variety of immune cells, which are critical to maintain normal tissue functions. For example, γδ T cells are fundamental for AT innervation and thermogenesis, and macrophages are required for recycling of lipids released by adipocytes. The expansion of visceral white AT promotes dysregulation of its immune cell composition and likely promotes low-grade chronic inflammation, which has been proposed to be the underlying cause for the complications of obesity. Interestingly, weight loss after obesity alters the AT immune compartment, which may account for the decreased risk of developing these complications. Recent technological advancements that allow molecular investigation on a single-cell level have led to the discovery of previously unappreciated heterogeneity in many organs and tissues. In this review, we will explore the heterogeneity of immune cells within the visceral white AT and their contributions to homeostasis and pathology.

Mathematical modeling of polystyrene particle size distribution produced by suspension polymerization (2000)

Particle size distribution (PSD) of polystyrene particles produced by suspension polymerization is of fundamental importance in determining suspension stability and product quality attributes. Within a population balance framework, a model is proposed for suspension polymerization reactors to describe the evolution of the PSD. The model includes description of breakage and coalescence rates in terms of reaction kinetics and rheology of the dispersed phase. The model is validated with experimental data of styrene suspension polymerization.
Apurinic DNA endonuclease activities in repair-deficient human cell lines (1978)

Several autosomal recessive diseases are associated with apparent DNA repair defects in cell culture. It seemed likely that a defect in excision repair reported for ataxia telangiectasia cells might reflect a lack of apurinic endonuclease activity. We report here normal levels of apurinic endonuclease activity in extracts of cell lines derived from patients with ataxia telangiectasia, xeroderma pigmentosum (complementation group D), Cockayne dwarfism, Fanconi anemia and Bloom syndrome.
Recurrent Periosteal Chondroma (1969)

Two cases of recurrent periosteal chondroma are described and the roenstgenographic and histopathological findings presented. The established tendency for recurrence in these lesions justifies block excision rather than enucleation.
Formation Kinetics of Chemically Vapor-Deposited Carbon on Mesoporous Silica (2007)

Formation kinetics of chemically vapor-deposited carbon on mesoporous silica was examined for its porous texture, activation energy and thermodynamic factors. The carbon was deposited by CVD using benzene, hexane and toluene. The amount of carbon in these hybrids increased with deposition in temperature and time. The increase of carbon resulted in decreases of their specific surface area and pore size. The density of carbon within mesopores in the hybrid prepared from benzene and toluene was around 0.6 and 1.9 g/cm3, respectively. For the hybrid modified with hexane, carbon was prone to enclose particles of the mesoporous silica. The activation energies of carbonization were estimated to be less than 100 kJ/mol for benzene and toluene; however, the energy from hexane was 279 kJ/mol. These energies imply that mesopores accelerate carbonization from benzene and toluene to form carbon within mesopores, and carbon was deposited on MPS particles for hexane. The estimated change of formation free energy (ΔGf) of hexane was smaller than those of benzene and toluene over the temperature range of these experiments. From these estimated ΔGf, hexane molecules tend to carbonize more quickly before introduction into mesopores than benzene and toluene. Eventually the lower ΔGf of hexane presumably possibly gives a large amount of deposited carbon on the surface of the mesoporous silica particles.
Synthesis and Structures of Potassium Bisdithiocarbamate Salts (2003)

Abstract Two structurally related dipotassium bisdithiocarbamate salts: K 2 [(S 2 CNRCH 2 ) 2 ](EtOH) 2 ; R = Me, i ‐Pr, were synthesised from the corresponding diamines. X‐ray structure determinations were performed on single crystals grown from ethanolic solutions. The different alkyl substituents have a profound affect upon the solid‐state structures, with the methyl derivative possessing a complex a 3‐D network and the isopropyl derivative a 2‐D lamellar structure.
