MULTIDISCIPLINARY APPROACH OF A PATIENT WITH MENTAL RETARDATION UNDER GENERAL ANESTHESIA : A CASE REPORT (2009)

Mental retardation is defined by the American Psychiatric Association as “subnormal general intellectualfunctioning which originates during the developmental period and is associated with impairment of eitherlearning and social adjustment or maturation, or both.”A patient with mild to moderate mental retardation can be managed adequately using restraints andmedications. However, in case of severe or profound mental disability, dental treatment cannot be accom-plished even with the use of behavior modification, physical restraints and sedation techniques. Whentreatment in the dental office has much difficulty, hospitalization for dental treatment under general anes-thesia can and should be considered.This case presents the treatment of a patient with mental retardation who was referred to our depart-ment for comprehensive dental care. Dental examination revealed widespread dental caries and a severeanterior open bite with crowding problems. Under general anesthesia, generalized caries treatment wasperformed by our department, and the anterior dental esthetics was achieved in collaboration with the de-partment of prosthodontic dentistry.Key words : Mental retardation, Collaboration, General anesthesia, Dental treatment
Determination and correction of distortions and systematic errors in low-energy electron diffraction (2013)

We developed and implemented an algorithm to determine and correct systematic distortions in low-energy electron diffraction (LEED) images. The procedure is in principle independent of the design of the apparatus (spherical or planar phosphorescent screen vs. channeltron detector) and is therefore applicable to all device variants, known as conventional LEED, micro-channel plate LEED, and spot profile analysis LEED. The essential prerequisite is a calibration image of a sample with a well-known structure and a suitably high number of diffraction spots, e.g., a Si(111)-7×7 reconstructed surface. The algorithm provides a formalism which can be used to rectify all further measurements generated with the same device. In detail, one needs to distinguish between radial and asymmetric distortion. Additionally, it is necessary to know the primary energy of the electrons precisely to derive accurate lattice constants. Often, there will be a deviation between the true kinetic energy and the value set in the LEED control. Here, we introduce a method to determine this energy error more accurately than in previous studies. Following the correction of the systematic errors, a relative accuracy of better than 1% can be achieved for the determination of the lattice parameters of unknown samples.

On the stability of tetrahedral intermediates within the active sites of serine and cysteine proteases (1983)

An empirical method used for the calculation of the equilibrium constants for the formation of tetrahedral intermediates in solutions is extended for the prediction of the stability of these intermediates within the active sites of several serine proteases and papain. It is concluded that there is very little chance of observing the accumulation of such an intermediate in the course of the hydrolysis of an amide or peptide by these enzymes.

Transported JPDF modelling and measurements of soot at elevated pressures (2022)

Accurate measurements and modelling of soot formation in turbulent flames at elevated pressures form a crucial step towards design methods that can support the development of practical combustion devices. A mass and number density preserving sectional model is here combined with a transported joint-scalar probability density function (JDPF) method that enables a fully coupled scalar space of soot, gas-phase species and enthalpy. The approach is extended to the KAUST turbulent non-premixed ethylene-nitrogen flames at pressures from 1 to 5 bar via an updated global bimolecular (second order) nucleation step from acetylene to pyrene. The latter accounts for pressure-induced density effects with the rate fitted using comparisons with full detailed chemistry up to 20 bar pressure and with experimental data from a WSR/PFR configuration and laminar premixed flames. Soot surface growth is treated via a PAH analogy and soot oxidation is considered via O, OH and O2 using a Hertz-Knudsen approach. The impact of differential diffusion between soot and gas-phase particles is included by a gradual decline of diffusivity among soot sections. Comparisons with normalised experimental OH-PLIF and PAH-PLIF signals suggest good predictions of the evolution of the flame structure. Good agreement was also found for predicted soot volume statistics at all pressures. The importance of differential diffusion between soot and gas-phase species intensifies with pressure with the impact on PSDs more evident for larger particles which tend to be transported towards the fuel rich centreline leading to reduced soot oxidation.
State-of-the-Art Predictions for C-parameter and a Determination of α (2016)

The C-parameter event-shape distribution for e+e− annihilation into hadrons is computed in the framework of SCET including input from fixed-order perturbation theory. We calculate all missing ingredients for achieving N3LL resummation accuracy in the cross section, which is then matched onto O(αs3) fixed-order results. Hadronization power corrections are incorporated as a convolution with a nonperturbative shape function. Wide-angle soft radiation effects introduce an O(ΛQCD) renormalon ambiguity in the cross section, which we cure by switching to the Rgap short-distance scheme. We also include hadron mass effects, but find their effect is rather small. Performing fits to the tail of the C-parameter distribution for many center of mass energies we find that the strong coupling constant is αs(mZ)=0.1121±0.0015, with χ2/dof=0.99.
Preparation and properties of high modulus–tensile strength polymeric materials (1980)

Abstract A two stage drawing procedure is described for producing highly oriented polymeric materials. The high orientation of both the crystalline and amorphous phase in the semi‐crystalline materials studied resulted in the materials possessing high mechanical properties. The ability to obtain high amorphous orientation is critical. Tensile strengths of 16 g/denier for polyethylene are determined, for example. The results suggest that the existence of a prominent crystalline dispersion mechanism (as observed in dynamical mechanical studies) is not necessary for the attainment of high mechanical properties. Thus a method was devised for the determination of the optimum drawing temperature.
Metal–Organic Phase-Change Materials for Thermal Energy Storage (2020)

The development of materials that reversibly store high densities of thermal energy is critical to the more efficient and sustainable utilization of energy. Herein, we investigate metal-organic compounds as a new class of solid-liquid phase-change materials (PCMs) for thermal energy storage. Specifically, we show that isostructural series of divalent metal amide complexes featuring extended hydrogen bond networks can undergo tunable, high-enthalpy melting transitions over a wide temperature range. Moreover, these coordination compounds provide a powerful platform to explore the specific factors that contribute to the energy density and entropy of metal-organic PCMs. Through a systematic analysis of the structural and thermochemical properties of these compounds, we investigated the influence of coordination bonds, hydrogen-bond networks, neutral organic ligands, and outer-sphere anions on their phase-change thermodynamics. In particular, we identify the importance of high densities of coordination bonds and hydrogen bonds to achieving a high PCM energy density, and we show how metal-dependent changes to the local coordination environment during melting impact the entropy and enthalpy of metal-organic PCMs. These results highlight the potential of manipulating order-disorder phase transitions in metal-organic materials for thermal energy storage.
The Effect of Monoclonal Anti-human-platelet Antibodies on Platelet Kinetics in a Baboon Model: IgG Subclass Dependency (2000)

We assessed the in vivo effect of six intact anti-human antiplatelet antibodies of two major IgG subclasses on platelet kinetics in baboons. Five of the six antibodies tested caused thrombocytopenia of varying degree when injected at a precalculated threshold value. An agglutinating IgG1 antibody (MA-8L4A12) caused a long-lasting, mild thrombocytopenia with a predominant uptake of radiolabelled platelets in the spleen, while the four IgG2 antibodies tested (MA-13G8E1, MA-2M5A6, MA-21K2E8 and MA-22M10) caused a severe, transient thrombocytopenia with uptake of platelets in the liver. Two of the IgG2 antibodies (MA-13G8E1 and MA-2M5A6) caused platelet activation and aggregation in vitro, whilst the other two did not elicit a platelet aggregation response. The platelet survival time was shortened with all five of the thrombocytopenia-inducing antibodies, while only one antibody (MA-2M5A6) had a significant effect on the bleeding time. This study indicates that the IgG subclasss may be a determining factor in the outcome of platelet sequestration in immune-induced thrombocytopenia.
Asperindoles A–D and a p-Terphenyl Derivative from the Ascidian-Derived Fungus Aspergillus sp. KMM 4676 (2018)

Four new indole-diterpene alkaloids asperindoles A⁻D (<b>1</b>⁻<b>4</b>) and the known <i>p</i>-terphenyl derivative 3&Prime;-hydroxyterphenyllin (<b>5</b>) were isolated from the marine-derived strain of the fungus <i>Aspergillus</i> sp., associated with an unidentified colonial ascidian. The structures of <b>1</b>⁻<b>5</b> were established by 2D NMR and HRESIMS data. The absolute configurations of all stereocenters of <b>1</b>⁻<b>4</b> were determined by the combination of ROESY data, coupling constants analysis, and biogenetic considerations. Asperindoles C and D contain a 2-hydroxyisobutyric acid (2-HIBA) residue, rarely found in natural compounds. Asperindole A exhibits cytotoxic activity against hormone therapy-resistant PC-3 and 22Rv1, as well as hormone therapy-sensitive human prostate cancer cells, and induces apoptosis in these cells at low-micromolar concentrations.
Cell lysis with dimethyl sulphoxide produces stable homogeneous solutions in the dichlorofluorescein oxidative stress assay (2008)

The oxidation of 2',7'-dichlorodihydrofluorescein (2',7'-dichlorofluorescin, DCFH) to a fluorescent product, 2',7'-dichlorofluorescein (DCF), is commonly used to quantitatively measure oxidative stress in cells using a fluorescence microplate reader. However, many cell lines tend to grow non-uniformly in the wells. This non-uniform distribution results in a high degree of variability in the fluorescence signal and decreases the precision of the method. Also, samples treated in large culture plates, dishes or flasks cannot be assayed directly in fluorescence microplate readers. This study reports an improved DCF assay method that lyses cells with DMSO/PBS (90% dimethyl sulphoxide/10% phosphate buffered saline). Oxidative stress was induced with either hydrogen peroxide or an hypoxia-reoxygenation treatment. Cell lysis with DMSO/PBS resulted in highly stable fluorescence signals in comparison to Triton X-100/PBS lysed cells. The precision of DCF fluorescence measurements of DMSO/PBS lysed cells was much better than for attached cells measured directly in 96-well plates. While DCF fluorescence in PBS was strongly quenched by albumin, no quenching occurred in DMSO/PBS. In conclusion this study describes a more convenient and accurate method for measuring cellular oxidative stress that also makes it possible to assay cells treated in large culture plates.
Preparation, characterization, and drug release behaviors of drug-loaded e-caprolactone/L-lactide copolymer nanoparticles (2000)

Copolymers of ε-caprolactone and L-lactide (PCLLA) with different monomer ratio were synthesized by ring opening polymerization, and drug-loaded nanoparticles of poly-ε-caprolactone (PCL), poly-L-lactide (PLLA), and their copolymers were prepared by precipitation method, respectively. The results of differential scanning calorimetry and X-ray diffraction indicated that the copolymerization of PCLLA decreased the crystallinity of the polymers, and the results of transmission electron micrograph and laser light scattering (LLS) revealed that the prepared nanoparticles had a spherical shape, and the size of PCLLA nanoparticles (∼ 85 nm) was smaller than that of the PCL and PLLA nanoparticles. The experiment of in vitro drug release showed that the drug release rate from PCLLA nanoparticles was slower than that from PCL and PLLA nanoparticles, and the release profile of PCL6/LA4 nanoparticles appeared to follow zero order kinetics. These results suggested that the polymer composition made a great influence on the nanoparticle size and drug release behavior. © 2000 John Wiley & Sons, Inc. J Appl Polym Sci 75: 874–882, 2000

Contribuição ao estudo das propriedades mecânicas dos concretos de alta resistência com e sem adições de microssílica. (1995)

Nesta pesquisa, estuda-se os efeitos do aumento da resistência do concreto nas suas propriedades mecânicas, mais especificamente, na resistência a compressão, resistência a tração na flexão, resistência a tração por compressão diametral, modulo de deformação e coeficiente de Poisson. Paralelamente, verifica-se de que forma adições de microssílica ou curas deficientes podem afetar estas propriedades mecânicas. Em conjunto com os ensaios de laboratório normalmente executados, realiza-se uma investigação da microestrutura utilizando-se microscópio eletrônico de varredura para o melhor entendimento do seu comportamento mecânico. Por fim, são propostas novas equações para estimar a resistência a compressão a partir dos parâmetros estudados (a/c, microssílica, cura e idade) e as relações entre resistência a tração e módulo de deformação com a resistência a compressão, levando em consideração os efeitos positivos da microssílica e os negativos causados pela cura em ambiente de laboratório. Como contribuição adicional, apresenta-se e testa-se uma metodologia que permite planejar experimentos semelhantes ao desenvolvido neste estudo, de forma fracionada, para que, com um número consideravelmente reduzido de ensaios, seja possível chegar as mesmas conclusões com confiabilidade estatística.
Long-term preservation of digital signatures for multiple groups of related documents (2012)

Increasing numbers of documents are currently being stored in electronic archives. These documents are often digitally signed to ensure non-repudiation. However, the term of validity of digital signatures is usually only 2 years, so the archive must extend their validity to the required storage period. The simplest solution to this problem is to use XAdES-A specification and process each signed document separately. Such an approach requires the creation of a timestamp for each signed document. This time stamping operation is very time consuming; therefore several improved techniques have been proposed, for example, evidence record syntax (ERS). The documents in an archive are often related to one entity. The ERS allows us to prove the existence of a document group in one round. This study presents a solution extending ERS and providing a functionality that enables proof of the existence of a document group over a long period (multiple rounds).
Design of Three Dimensional Spatial Topological Relational Operators (2003)

지리정보시스템은 3차원 위상정보를 표현함으로써 사용자에게 정확하고 정교한 서비스를 제공한다. 이 때에 3차원 위상정보연산을 위해 차원변경방식과 서로 이질적인 공간모델을 사용해야 하는데, 이 방식을 사용할 때는 공간 연산이 어려울 뿐 아니라 서로 호환성이 부족한 문제가 발생한다. 따라서 이 논문에서는 이 문제를 해결하기 위하여 2차원 공간 객체 모델을 수용하는 3차원 공간 객체 모델을 제안하였고, 타당성을 보이기 위하여 구현하여, 그 실행을 보였다. 3차원 공간 위상 관계 연산자를 위하여 DE-9IM 방식을 3차원 개념으로 정의한 DE-9IM을 이용해서 설계하였고, 객체지향 개념을 지원하는 컴포넌트 환경에서 3차원 공간 위상 연산자를 구현하였다. 이 논문에서 제안된 3차원 공간 위상 연산자는 타 시스템과의 상호 운용성을 보장하며, 구현된 공간 위상 관계 연산을 이용하여, 3차원 공간 객체에 대한 효율적인 공간 질의를 수행할 수 있다. As Geographic Information Systems represent three dimensional topological information, The Systems provide accurate and delicate services for users. In order to execute three dimensional topological operations, a dimensional transformation and heterogeneous spatial models should be used. However, the existing systems that use the dimensional transformation and the heterogeneous models, is not only difficult to operate the spatial operators, but also happened to support non-interoperability. Therefore, in order to solve the problems, we proposed three dimensional spatial object models that supported two dimensional object models and implemented them to show validity of the proposed models. When designing the three dimensional topological operators, we used 3DE-9IM which extended DE-9IM to support three dimensional concepts, and implemented operators on the component environment with object oriented concepts. The proposed three dimensional spatial object models and topological operators can support interoperability between systems, and execute spatial queries efficiently on three dimensional spatial objects.
Stemming and Lemmatization: A Comparison of Retrieval Performances (2014)

The current study proposes to compare document retrieval precision performances based on language modeling techniques, particularly stemming and lemmatization. Stemming is a procedure to reduce all words with the same stem to a common form whereas lemmatization removes inflectional endings and returns the base or dictionary form of a word. Comparisons were also made between these two techniques with a baseline ranking algorithm (i.e. with no language processing). A search engine was developed and the algorithms were tested based on a test collection. Both mean average precisions and histograms indicate stemming and lemmatization to outperform the baseline algorithm. As for the language modeling techniques, lemmatization produced better precision compared to stemming, however the differences are insignificant. Overall the findings suggest that language modeling techniques improves document retrieval, with lemmatization technique producing the best result.
Interaction Effects of Predominantly Linear and Branched Waxes on Yield Stress and Elastic Modulus of Waxy Oils (2018)

To assess the relationship of wax chemical structure and viscoelastic properties of waxy gels, model oils composed of single and blended waxes were prepared at a fixed concentration of 7.5 wt % and then gelled. The investigation encompassed four different well-characterized commercial paraffin waxes, solubilized in a mineral oil matrix. Previous rheological measurements pointed out that these systems reproduce essential features of crude oil gels (e.g., gel-like mechanical response) when gelled. Among the employed waxes, two are predominantly linear, whereas the others are nonlinear branched molecules. The waxes were molecularly characterized to aid in the investigation by means of GC-FID, 13C NMR, DSC, FT-IR, and XRD. Rheological properties were measured via a controlled-stress rheometer by oscillatory shear experiments. Polarized light microscopy was adopted for morphological characterization of precipitated crystals. It was found that yield stress and elastic modulus at linear viscoelastic region are highly correlated (R2 = 0.94). For single wax systems, the increase in chain length resulted in a yield stress increase, although there is a competitive effect among chain length (positive effect) and branching content (negative effect). The results indicated that for blended systems the small-chain linear wax was able to interact favorably with the long-chain nonlinear wax, possibly due to its ability to accommodate within the later molecule, ensuring the highest yield stress value (630.2 Pa). The wax structural arrangement of 37 carbon atoms on average, including approximately three tertiary carbons, was effective for lowering the yield stress of particular blended systems. The lowest viscoelastic properties were measured for a blended system composed of nonlinear waxes, which was also characterized by the smallest and rounded crystals visible by optical microscopy.
BRONCHIAL BIOPSY EVIDENCE FOR LEUKOCYTE INFILTRATION AND UPREGULATION OF LEUKOCYTE-ENDOTHELIAL CELL ADHESION MOLECULES 6 HOURS AFTER LOCAL ALLERGEN CHALLENGE OF SENSITIZED ASTHMATIC AIRWAYS (1995)

Endobronchial allergen challenge in allergic asthmatics leads to a decrease in pulmonary function, and an increase in bronchial hyperresponsiveness within 24 hours, and an influx of inflammatory cells (neutrophils, eosinophils, mast cells, and lymphocytes) within 6 hours. In addition, 6 hours postallergen challenge, an increase was detected in the expression of several endothelial cell adhesion molecules (ICAM, E-selectin), which are essential for inflammatory cell migration.
A two-beam slotted leaky waveguide array for mobile reception of dual polarization DBS (2002)

Mobile reception of direct broadcast satellites (DBS) has been very popular and the number of vehicles with DBS receiving systems is also rapidly increasing in Japan. Low-profile, mass-produceable, beam-tilting and high-efficiency receiving antennas had been desired to this end. We developed a single-layer slotted leaky waveguide array antenna for the single-polarized DBS in Japan which satisfies all these requirements. A novel single layer feed structure is applied to the antenna, which consists of cascades of /spl pi/-junctions and radiating waveguides as shown. The cross slots are densely arranged on the broad wall of the radiating waveguides. The leaky wave radiates a circular polarized beam in a large tilting angle of about 45 degrees from the zenith. It is advantageous for mobile DBS reception since the antenna can be installed horizontally on the roof of vehicles. A mechanical system steers the antenna to track the satellite only in the azimuthal plane. Tracking is not necessary in the elevation plane, since the beam width of the antenna with a short radiating waveguide is broad.
Multi-kilowatt power scaling and coherent beam combining of narrow-linewidth fiber lasers (2016)

We report results from two ~1.5 kW Yb-doped fiber amplifiers with comparable optical to optical efficiencies and linewidths. One amplifier utilized a fiber with a core diameter of 25 &mu;m while the core diameter of the fiber utilized in the other amplifier was 20 &mu;m. Stimulated Brillouin scattering (SBS) suppression in both cases was achieved through pseudo-random bit sequence (PRBS) phase modulation. While the power generated in the larger core fiber was modal instability (MI) limited, no sign of MI was observed in the smaller core fiber. This may allow us to utilize the higher MI threshold fiber to scale further while maintaining sufficiently narrow linewidth for beam combining. Furthermore, in a demonstration of the utility of applying a thermal gradient in conjunction with phase modulation to suppress SBS further, we report on a 1 kW amplifier driven at a PRBS clock rate of 2 GHz. Finally, we compare the coherent beam combining properties of amplifiers seeded with PRBS phase modulated sources to those seeded with white noise sources.
