Phase behavior and photocrosslinking kinetics ofsemi-interpenetrating polymer networks prepared from miscible polymer blends (1998)

Mixtures of polystyrene derivatives (PSCS) and poly(vinyl methyl ether) (PVME) were made photocrosslinkable by chemically labeling PSCS chains with photoreactive anthracene. Miscibility of these anthracene-labeled PSCS/PVME blends was examined by light scattering under several crosslinking conditions in the one-phase region via photodimerization of anthracenes. As the reaction proceeds, the coexistence curve of PSCS/PVME blends shifts toward the low temperature side. By following the changes in concentration of anthracenes with irradiation time, it was found that the crosslinking reaction of PSCS chains in the blends does not follow the mean-field kinetics. However, it can be well expressed by the Kohlrausch–Williams–Watts (KWW) relaxation mechanism, indicating that the crosslinking reaction proceeds inhomogeneously in the blends. By scaling the reaction time with the average reaction rate obtained from the KWW equation modified for the reaction kinetics, all the crosslinking data obtained in the miscible region of the reacted blends fall on a single master curve. These experimental results suggest the universal behavior of the photocrosslinking kinetics obtained under the “shallow quench” conditions in the region far away from the coexistence curve of the reacting blends. © 1998 John Wiley & Sons, Inc.

Comparison of the erosion resistance of silicone rubber and EPDM composites filled with micro silica and ATH (2012)

The paper presents the results of inclined plane tests on ATH and silica composites of Silicone rubber (SiR) and EPDM to evaluate the effect of filler type and loading on the tracking and erosion resistance of the composites formed. The effect of test voltage on the outcome of the incline plane was also examined. A laser ablation test was also used to evaluate the various composites. A critical test voltage of 4.5 kV was shown to cause failures in samples which emphasizes the importance of testing composites at voltages above this critical level. In comparing the two test methods, both the inclined plane and laser ablation test methods showed the same order for EPDM composites of ATH and silica while the laser method showed silica SiR composites to perform somewhat better than in the inclined plane test which showed similar results.
Multiscale Visualization of 3D Geovirtual Environments Using View-Dependent Multi-Perspective Views. (2011)

3D geovirtual environments (GeoVEs), such as virtual 3D city models or landscape models, are essential visualization tools for\neffectively communicating complex spatial information. In this paper, we discuss how these environments can be visualized using\nmulti-perspective projections [10, 13] based on view-dependent global deformations. Multi-perspective projections enable 3D\nvisualization similar to panoramic maps, increasing overview and information density in depictions of 3D GeoVEs. To make\nmulti-perspective views an effective medium, they must adjust to the orientation of the virtual camera controlled by the user and\nconstrained by the environment. Thus, changing multi-perspective camera configurations typically require the user to manually\nadapt the global deformation — an error prone, non-intuitive, and often time-consuming task. Our main contribution comprises\na concept for the automatic and view-dependent interpolation of different global deformation preset configurations (Fig. 1).\nApplications and systems that implement such view-dependent global deformations, allow users to smoothly and steadily interact\nwith and navigate through multi-perspective 3D GeoVEs.

FTIR and Resonance Raman Studies of Nitric Oxide Binding to H93G Cavity Mutants of Myoglobin (2001)

Nitric oxide (NO) binds to the myoglobin (Mb) cavity mutant, H93G, forming either a five- or six-coordinate Fe-NO complex. The H93G mutation eliminates the covalent attachment between the protein and the proximal ligand, allowing NO to bind H93G possibly from the proximal side of the heme rather than the typical diatomic binding pocket on the distal side. The question of whether NO binds on the distal or proximal side was addressed by FTIR spectroscopy of the N-O vibrational frequency nuN(-O) for a set of Mb mutants that perturb the electrostatic environment of the heme pocket. Vibrational spectra of five- and six-coordinate MbNO complexes indicate that nu(N-O) shifts (by as much as 26 cm(-1)) to higher energies for the distal mutants H64V and H64V/H93G relative to the energies of wild-type and H93G MbNO, while nu(N-O) is not affected by the proximal side mutation S92A/H93G. This result suggests that NO binds on the distal side of heme in the five- and six-coordinate MbNO complexes of H93G. Additionally, values of the Fe-NO vibrational frequency nu(Fe-NO) as measured by resonance Raman spectroscopy are reported for the distal and proximal double mutants of H93G. These results suggest that nu(Fe-NO) is not very sensitive to mutations that perturb the electrostatic environment of the heme pocket, leading to the observation that nu(N-O) and nu(Fe-NO) are not quantitatively correlated for the MbNO complexes presented here. Furthermore, nu(N-O) and nu(Fe-NO) do not correlate well with equilibrium constants for imidazole binding to the five-coordinate MbNO complexes of the H93G double mutants. The data presented here do not appear to support the presence of pi-back-bonding or an inverse trans effect of NO binding in Mb mutants that alter the electrostatic environment of the heme pocket.
Etiology and Characteristics of Massive Pleural Effusions Investigated at One University Hospital in Korea (2006)

Background: Differential diagnosis is very important in patients with pleural effusions. A few studies on the etiologies of massive pleural effusions have been reported, but these were conducted in different decades and locations. In the present study, the etiologic spectrum of massive pleural effusions in Korea, were evaluated through an investigation at one university hospital. Methods: Retrospective chart reviews were performed in patients having undergone thoracentesis between July 2002 and July 2005. Pleural effusions were deemed to be massive if they occurred in two thirds or more of one hemithorax. The etiologies of massive pleural effusions, pleural fluid findings, serum laboratory findings, and sputum and pleural fluid cytologies were compared. Results: Of 298 pleural effusions cases, 41 (13.8%) had massive pleural effusions. The most frequent causes of massive pleural effusions were malignancy (19; 46.3%) followed by tuberculosis (15; 36.6%), parapneumonic effusion (4; 9.8%) and transudate (3; 7.3%). Compared with massive benign effusions, patients with massive malignant pleural effusions were more likely to have lower adenosine deaminase (ADA) activity, a higher amylase level and higher RBC count in their pleural fluids. Also, compared with non-tuberculosis effusions, patients with massive tuberculous pleural effusions were more likely to have lower RBC and neutrophil counts, but a higher lymphocyte count, adenosine deaminase (ADA) activity and protein level. Conclusion: The most common etiologies of massive pleural effusions in Korea are malignancy and tuberculosis. A high ADA content favors a tuberculous condition, while bloody effusions with a relatively lower ADA content. favors malignancy. The proportion of tuberculosis in massive pleural effusions was higher than in previous reports.

Electronic band gaps and exciton binding energies in monolayerMoxW1−xS2transition metal dichalcogenide alloys probed by scanning tunneling and optical spectroscopy (2016)

Using optical absorption and scanning tunneling spectroscopy techniques, the authors investigate band-gap properties of single layers of transition metal dichalcogenide (TMDC) alloyed crystals (Mo${}_{x}$W${}_{1-x}$S${}_{2}$). They observe a significant modulation of the excitonic transitions, quasiparticle band gaps, and exciton binding energies. These findings may hold promise for fundamental studies of intralayer phenomena and for potential applications of TMDC alloys in electronic and optoelectronic devices.

Epigenetic Marking Prepares the Human HOXA Cluster for Activation During Differentiation of Pluripotent Cells (2008)

Activation of Hox gene clusters is an early event in embryonic development since individual members play important roles in patterning of the body axis. Their functions require precise control of spatiotemporal expression to provide positional information for the cells of the developing embryo, and the manner by which this control is achieved has generated considerable interest. The situation is different in pluripotent cells, where HOX genes are not expressed but are held in potentio as bivalent chromatin domains, which are resolved upon differentiation to permit HOX cluster activation. In this study we have used differentiation of the pluripotent embryonal carcinoma cell line NTera2SP12 and the human embryonic stem cell line H9 to examine epigenetic changes that accompany activation of the HOXA cluster and show that specific genomic loci are marked by lysine methylation of histone H3 (H3K4 tri- and dimethyl, H3K9 trimethyl) and acetylation of histone H4 even in the undifferentiated cells. The precise locations of such modified histones may be involved in controlling the colinear expression of genes from the cluster.

Corrosion behaviour of thermal cycled aluminium hybrid composites reinforced with rice husk ash and silicon carbide (2016)

The corrosion behaviour of aluminium hybrid composites reinforced with rice husk ash and silicon carbide subjected to thermal cycling has been investigated. Aluminium hybrid composites having 10 wt% reinforcement consisting of silicon carbide (SiC) and rice husk ash (RHA) in weight ratios of 1:0, 3:1, 1:1, 1:3, and 0:1 respectively were produced. The composites were subjected to varying thermal cycles of 6, 12 and 18 from room temperature to 200 °C repeatedly. Potentiodynamic polarization measurements were used to study the corrosion behaviour of the produced composites. The results show that the composites displayed similar polarization curves and passivity characteristics irrespective of the number of thermal cycles both in H2SO4 and NaCl solutions. No consistent trend of corrosion current density changes with increase in thermal cycling was established for composite grades 3:1, 1:1 in H2SO4 and 1:0, 0:1 and 3:1 in NaCl solutions. The hybrid composite grades with a higher RHA content generally exhibited a lower tendency to corrode compared to the other composite grades. Generally, the composites seemed to be structurally stable as they maintained their corrosion resistance levels even after exposure to thermal cycling.

Engineering Nanomaterials to Use in Biomedical Applications and in Examining Toxicology (2012)

Mesoporous silica nanoparticles (MSNs) have been shown to be useful in numerous applications, because the surface can be easily modified with various functional groups. MSNs can also be modified with respect to the interior or exterior of the particles: materials can be condensed within the silica framework, attached along the pore walls, or bound to the outer surface of the nanoparticles. Surface modifications with molecular machines can act to contain cargo molecules within the porous structure for stimulated release of the cargo. Additionally, materials have been developed that contain small metal oxide nanocrystals (d = 10-20 nm) encapsulated within a single MSN. These core-shell mesoporous materials can be used to examine toxicological properties of dissolved ions apart from their cell-surface interactions, since the porous shell allows for diffusion of ions through the porous channels, while also physically isolating the nanocrystal surface from direct contact with the biological material. Additionally, the outer surface of these core-shell MSNs can be modified with molecular machines for cargo storage and release. When iron oxide nanocrystals are encapsulated within MSNs that are equipped with nanovalves and exposed to high-frequency magnetic fields, the valves open and release cargo molecules from the nanoparticles. This property is used to deliver drug molecules in vitro. Furthermore, molecules can be covalently attached to the surface to direct the nanoparticles into certain cells. Cancer cells overexpressing transferrin receptors show enhanced uptake toward MSNs functionalized with surface-attached transferrin. When examined in vitro, these particles show increased uptake of MSNs compared to MSNs without surface-attached transferrin. This dissertation will include research on these two major research aims using MSNs: biological aims of specific drug delivery into target cells; and examining the environmental toxicity of engineered nanomaterials.

[Mortality of dilated myocardiopathies as a function of continuation of alcohol drinking. Multivariate analysis concerning 236 patients]. (1989)

A retrospective study was conducted in 236 consecutive patients with dilated cardiomyopathy to determine the characteristics of the disease in heavy alcohol drinkers (n = 110) and to study its outcome, using a Cox model, according to whether the patients were abstainers (n = 49) or continued to indulge drinking (n = 61). At the time of diagnosis, pulmonary pressures were higher in heavy drinkers than in abstainers. During a mean follow-up period of 39 +/- 27 months, 80 patients died of heart disease, viz.: 46 out of 127 non-alcoholic patients (36.2 per cent), 31 out of 61 heavy drinkers (50.8 per cent) and 3 out of 49 patients who had given up alcohol (6.12 per cent). Thus, independently of other parameters, abstinence is a highly significant (P less than 0.001) factor of favourable prognosis in dilated cardiomyopathy.
Director tilting of liquid crystals on photoisomerizable polyimide alignment layers doped with homeotropic surfactant (1999)

Director tilting of liquid crystal (LC) molecules on photosensitive alignment layers has been investigated. The layers, polyimides with photoisomerizable groups in their main chains, were irradiated with unpolarized near-UV (UPUV) light at oblique incidence. The irradiated film was found to align LC molecules homogeneously with a negligible pretilt angle. It was found that the pretilt angle can be generated successfully by introducing surfactant lecithin and decreasing the incidence angle of the UPUV light. The LC alignment and electro-optical properties of the LC cells with the photoalignment layers were demonstrated to be suitable for twisted nematic LC, vertical alignment LC, and surface-stabilized ferroelectric LC devices.
The conversion of isotopically labeled glycine to 1‐methyl‐2‐amino‐2‐imidazolin‐4‐one (creatinine) (1972)

Abstract A procedure is presented which allows the conversion of glycine to creatinine (1‐methyl‐2‐amino‐2‐imidazolin‐4‐one). The scheme was devised to optimize the yield based on the amount of glycine used so that the relatively readily available isotopically labeled glycines could be efficiently converted to the correspondingly labeled creatinines. In this case 1‐( 13 C)‐glycine was converted to 4‐( 13 C)‐1‐methyl‐2‐amino‐2‐imidazolin‐4‐one.
Human control of dynamically complex objects (2012)

Humans interact with a variety of objects, many of which have dynamically complex properties, such as a cup of coffee. An efficient way to manipulate such objects is to drive them at a resonant frequency. This requires less effort due to dynamic amplification of control inputs. However, errors in control may also be amplified, increasing variability and making it difficult to achieve a kinematic goal. How humans control dynamically complex objects near a resonant frequency, while at the same time achieving kinematic goals, is unknown. To address this question, ten healthy subjects were asked to practice oscillating a cart and pendulum (simulated using a haptic display). Subjects had to move the cart between two spatial targets at the pendulum's resonant frequency. A visual display showed the pendulum bob moving in a semicircular cup (the cart was hidden), mimicking a ball rolling in a cup. Results showed that in early practice subjects moved below the resonant frequency and used an in-phase strategy - the cup and ball moved in the same direction. This was associated with large applied forces and high variability. With practice subjects moved above the resonant frequency and switched to an anti-phase strategy - the cart and pendulum moved in opposite directions. Concurrently, subjects' applied force decreased by half and the interaction force of the ball on the cup increased, which moved the cup to the spatial targets. Using this strategy, subjects became less variable and more accurate. Although the switch in phasing was in part dictated by the task dynamics, the direction of the shift is best explained by a controller that seeks to exploit the dynamics of an object to achieve task goals with small outlays of energy and low variability.
