Effects of reduced dissolved oxygen concentration on jet fuel deposit formation (1995)

Currently, jet fuel is circulated through aircraft components to remove generated heat. Upon heating, jet fuel reacts with dissolved oxygen gas to produce oxidized products and deposits. This paper investigates the possibility of reducing oxygen concentration in jet fuel to inhibit deposit formation
The lungs and vitamin A (1992)

Evidence is reviewed supporting the view that vitamin A (retinol) and its metabolite, retinoic acid, called natural retinoids, are major factors involved in differentiation and in maturation of the lungs. This conclusion is based on morphological observation that lack of this dietary micronutrient causes keratinizing squamous metaplasia of the bronchopulmonary tree that can be reversed by refeeding the animal with retinol. In addition to these observations suggesting an indirect participation of retinol and/or retinoic acid in the differentiation of this organ, more direct evidence is presented that this vitamin is involved in pulmonary gene expression. Adult as well as fetal lungs accumulate retinyl esters, the storage form of vitamin A, contain specific retinol- and retinoic acid-binding proteins and, more importantly, express several isoforms of nuclear retinoic acid receptors. These proteins are involved in activation and repression of specific genes regulated by retinoic acid. That retinol and/or retinoic acid may be involved in lung maturation is suggested by experimental results showing depletion of lung retinyl esters at birth, by significant alterations in the levels of the cellular retinoic acid-binding protein during lung maturation and, more importantly, by reduction in the morbidity of prematurely born human neonates who are given vitamin A because they are susceptible to bronchopulmonary dysplasia.
Injectable thermosensitive hydrogels for intra‐articular delivery of methotrexate (2011)

Abstract Intra‐articular drug delivery is the preferred approach for targeting pharmacologic treatment directly at the joints to reduce undesirable side effects associated with systemic drug delivery. In this study, a controlled delivery system of methotrexate (MTX) based on injectable thermosensitive poly(ε‐caprolactone)‐poly(ethylene glycol)‐poly(ε‐caprolactone) (PCL‐PEG‐PCL, PEP) hydrogels was developed for the intra‐articular drug delivery. The thermosensitive PEP copolymers were prepared by ring‐opening polymerization. The synthesized PEP copolymers were characterized for their structure, composition, and the sol‐to‐gel transition. The in vitro MTX release from the PEP hydrogels was studied. MTX plasma concentration following intra‐articular injection into healthy rats was determined by HPLC. Biocompatibility was confirmed by histology analysis after the intra‐articular injection. The synthesized PEP copolymers aqueous solutions formed in situ gel rapidly after the injection. PEP hydrogels showed the ability to control the release of incorporated MTX. Following intra‐articular injection, the PEP hydrogels decreased the clearance rate of MTX in the joint cavity. The maximum plasma concentrations of MTX in rats injected with free MTX were threefold higher than that of the groups injected with MTX hydrogels. These results suggest that the intra‐articular delivery of the PEP hydrogels may be a viable strategy for the controlled release of drugs for treating arthritis diseases. © 2011 Wiley Periodicals, Inc.

Development of situation-aware application software for ubiquitous computing environments (2003)

Ubiquitous computing represents the concept of computing everywhere, making computing and communication essentially transparent to the users. Applications in this type of environments are context sensitive. They use various contexts to adaptively communicate with each other across multiple network environments, such as mobile ad hoc networks, Internet, and mobile phone networks. The property of context-sensitivity often becomes inadequate in these applications, where combinations of multiple contexts and users' actions need to be analyzed over a period of time. Situation-awareness in application software is considered as a desirable property to overcome this limitation. In addition to being context-sensitive, situation-aware applications can respond to both current and historical relationships of specific contexts and device-actions. Currently, no well-defined concept of situation and no general method exist to facilitate the development of situation-aware application software for ubiquitous computing environments. In this paper, the concept of situation is formalized, and an approach to developing situation-aware application software is presented. The approach utilizes our reconfigurable context-sensitive middleware, and is illustrated by an example on Smart Classroom.

PRONTO 3D: A three-dimensional transient solid dynamics program (1989)

PRONTO 3D is a three-dimensional transient solid dynamics code for analyzing large deformations of highly nonlinear materials subjected to extremely high strain rates. This Lagrangian finite element program uses an explicit time integration operator to integrate the equations of motion. Eight-node uniform strain hexahedral elements are used in the finite element formulation. A number of new numerical algorithms which have been developed for the code are described in this report. An adaptive time step control algorithm is described which greatly improves stability as well as performance in plasticity problems. A robust hourglass control scheme which eliminates hourglass distortions without disturbing the finite element solution is included. All constitutive models in PRONTO are cast in an unrotated configuration defined using the rotation determined from the polar decomposition of the deformation gradient. An accurate incremental algorithm was developed to determine this rotation and is described in detail. A robust contact algorithm was developed which allows for the impact and interaction of deforming contact surfaces of quite general geometry. Numerical examples are presented to demonstrate the utility of these algorithms. 34 refs., 27 figs., 12 tabs.
A novel photo-thermal setup for determination of absorptance losses and wavefront deformations in DUV optics (2008)

Lens heating due to absorbed UV laser radiation can diminish the achievable spatial resolution of the lithographic process in semiconductor wafer steppers. At the Laser- Laboratorium Göttingen a measurement system for quantitative registration of this thermal lens effect was developed. It is based upon a strongly improved Hartmann-Shack wavefront sensor with extreme sensitivity, accomplishing precise online monitoring of wavefront deformations of a collimated test laser beam transmitted through the laser-irradiated site of a sample. Caused by the temperature-dependent refractive index as well as thermal expansion, the formerly plane wavefront of the test laser is distorted to form a rotationally symmetric valley, being equivalent to a convex lens. The observed wavefront distortion is a quantitative measure of the absorption losses in the sample. Thermal theory affords absolute calibration of absorption coefficients.
A modeling tool for joining RF communications with IP networks (2008)

Current communication network design tools are particularly accessible to specialists in network planning and design; but do not provide an interface that is specifically useful for the communication system planners and engineers. Communication and network system architects, engineers, and integrators need access to simple, intuitive tools for performing system trades and analyses of complex, layered, system of systems architectures, such as the end to end communication systems for the Missile Defense Agency (MDA) Ballistic Missile Defense System (BMDS). A new tool for modeling the communication among the multiple disparate nodes in the BMDS into interconnected Internet Protocol (IP) compliant networks is now in development via a Small Business Innovative Research (SBIR) development contract with the MDA. The capability of the tool, called the Communications System Taxonomy (CommTax) Toolkit, is used in this paper to demonstrate how it will be applied to model the network needed to support a typical BMDS scenario.

Potential Use of Alien Germplasm for Maize Improvement<sup>1</sup> (1984)

Plant breeders have demonstrated the potential ability of exotic and alien germplasm to enhance particular qualitative genetic traits of maize, ( Zea mays L.). Results from such programs include the incorporation of genes that condition resistance to pathogens or insect pests. Fewer examples exist which provide information on how alien and exotic germplasm affect quantitative traits, although studies have shown it is possible to increase heterosis or to expand the level of genetic divergence between breeding populations by using such germplasm. However, in either case, most breeders prefer current, elite inbreds with known combining ability as sources for inbred development and for improvement of hybrid performance. Alien germplasm was evaluated for its effects on quantitative traits by crossing seven substitution lines, each containing various segments of germplasm from teosinte ( Zea mexicana ), with three testers, and measuring the effects on maize hybrids. A performance trial was used for this evaluation from which data were collected for 12 traits on 23 hybrids. Significant differences in grain yield and heterosis were obtained between the means of the three testers and among the various substitution line hybrids. One tester, Havels‐(20 + 2Tr7), contained an extra disomic chromosome from Tripsacum dactyloides . Hybrids with this tester had a combining ability value 8% higher than the isogenic control. The highest yielding hybrids were the teosinte A158‐substitution lines involving the Florida and Durango teosinte types crossed with the Havels testers. The two highest yields occurred from crossing the Havels tester containing the Tripsacum chromosome with the A158‐Florida 4,9 and the A158‐Florida 9 teosinte substitution lines.

Amino Acid and Vitamin Composition of Saccharomyces Fragilis Grown in Whey (1961)

Summary Saccharomyces fragilis grown in a whey medium was analyzed for amino acid and vitamin contents. Qualitatively, the amino acid composition of S. fragilis was similar to that reported for other yeasts. The quantity of the individual amino acids, however, was greater in the whey-grown S. fragilis . Lysine, in particular, was present at the level of 11.14 g/16g. N, compared to the range of 3.8 to 6.9 g/16g. N found in other microorganisms. An extraction procedure applied to whole, dried S. fragilis cells removed 40% of the total weight and 28% of the N of the cell preparation. The amino acid composition of the residual protein fraction was the same as that of the whole cells, but the amounts of the component amino acids varied from 35% of the histidine to 100% of the serine and valine in the whole cell preparation. Thiamine, pyridoxine, riboflavin, niacin, folic acid, pantothenic acid, p-aminobenzoic acid, choline, inositol, and biotin were present in S. fragilis in concentrations within the ranges reported for other microorganisms.
A Neoadjuvant/Adjuvant Randomized Trial of Colorectal Cancer Patients Vaccinated with an Anti-Idiotypic Antibody, 105AD7, Mimicking CD55 (2006)

Immune responses to vaccination were induced in a majority of monitored patients measured by ELISPOT and proliferation assay. The lack of correlation between the ELISPOT and proliferation assays may reflect the fact that the two methods measure different T-cell responses and highlights the importance of multiple readouts in evaluating a potential cancer vaccine. Responses to both the anti-idiotype and the CD55 antigen were measurable, adding support to the use of CD55 as a target in cancer treatment.
Control of Postpartum Hemorrhage Using Vacuum-Induced Uterine Tamponade (2016)

Thermocapillary migration of a two-dimensional liquid droplet on a solid surface (1995)

A two-dimensional liquid droplet placed on a non-uniformly heated solid surface will move towards the region of colder temperatures if the temperature gradient in the solid surface is large enough. Such behaviour is analysed for a thin viscous droplet using lubrication theory to develop an evolution equation for the shape of the droplet. For the small mobility capillary numbers examined in this work, the contact-line motion is controlled by a dynamic relationship posed between the contact-line speed and the apparent contact angle. Results are obtained numerically and also approximately using a perturbation technique for small heating. The initial spreading or shrinking of the droplet when placed on the heated solid is biased toward the direction of decreasing temperature on the solid. Possible steady-state responses are either a motionless droplet or one moving at a constant velocity down the temperature gradient without change in shape. These behaviours are the result of a thermocapillary recirculation cell inside the droplet that distorts the free surface and alters the apparent contact angles. This change in the apparent contact angles then modifies the contact-line speed.
Applications of hysteresis switching in parameter adaptive control (1992)

The hysteresis switching algorithm of R.H. Middleton et al. (ibid., vol.33, no.1, p.50-8, Jan. 1988) is reexamined in a broader context. To demonstrate its utility, the algorithm is applied to various families of identifier-based parameterized controllers of both the direct and indirect control types. Application to the direct control type results in a model reference adaptive controller capable of stabilizing, without excitation, any SISO process which can be modeled by a minimum phase linear system whose transfer function has relative and McMillan degrees not exceeding prescribing integers m and n, respectively. It is shown that such processes can also be adaptively stabilized with indirect adaptive controllers and hysteresis switching. A simple numerical example involving a non-minimum-phase process model is used to illustrate how hysteresis switching might be applied to implicitly tuned parameterized controllers to realize an adaptive controller with capabilities which might prove very difficult, if not impossible, to achieve without hysteresis switching or some other form of discontinuous control.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
In various tumour cell lines the peptide bradykinin B<sub>2</sub> receptor antagonist, Hoe 140 (Icatibant), may act as mitogenic agonist (2000)

This study examined the mitogenic effects of bradykinin (BK, Arg-Pro-Pro-Gly-Phe-Ser-Pro-Phe-Arg), the peptide bradykinin B(2) receptor antagonist Hoe 140 (D-Arg(0)[Hyp(3)-Thi(6)-D-Tic(7)-Oic(8)]BK, and the orally active, nonpeptide B(2) receptor antagonist FR 173657 ((E)-3-(6-acetamido-3-pyridyl)-N-[N-2-4-dichloro-3-[(2-methyl-8-quino linyl) oxymethyl]phenyl]-N-methylaminocarbonyl-methyl]acrylamide) in three different human tumour cell lines: the small cell lung carcinoma (SCLC) cell line H-69, the breast carcinoma cell line EFM-192A, and the colon carcinoma cell line SW-480. In these cell lines activation of mitogen-activated protein kinase (MAPK) is involved in BK-induced stimulation of cell proliferation and may be mediated by both G(q) proteins (SW-480) and G(i) proteins (EFM-192A; H-69). In these cells BK as well as Hoe 140 increased the rate of DNA synthesis measured with the [(3)H]-thymidine uptake assay. Hoe 140 did neither antagonize nor potentiate the effect of BK. FR 173657 did not stimulate [(3)H]-thymidine incorporation but clearly antagonized the mitogenic effects of BK as well as Hoe 140. In H-69 cells, FR 173657 induced a decrease in the basal rate of DNA synthesis. In all three cell lines BK and Hoe 140 stimulated the activity of MAPK. Their effect on MAPK activity was completely abolished by FR 173657 which itself did not increase the activity of MAPK. In H-69 cells, the basal activity of MAPK was slightly inhibited by FR 173657. In the cell lines SW-480 and H-69 both BK and Hoe 140 but not FR 173657 stimulated phosphatidylinositol hydrolysis. In H-69 cells, FR 173657 decreased basal inositol phosphate formation. Our results show that in certain tumour cell lines the classical peptide B(2) receptor antagonist, Hoe 140, may act as mitogenic B(2) receptor agonist whereas the nonpeptide B(2) receptor antagonist, FR 173657, does not. In H-69 cells FR 173657 was found to exhibit properties of an inverse agonist.
Graphene Nanoribbon Thin Films Using Layer-by-Layer Assembly (2010)

Described here is a room temperature procedure to fabricate graphene nanoribbon (GNR) thin films. The GNRs, synthesized by unzipping carbon nanotubes, were reduced and functionalized. The functionalized GNRs are negatively or positively charged, which are suitable to assemble thin films by electrostatic layer-by-layer absorption. The homogenous full GNR films were fabricated on various substrates with controllable thicknesses. By assembling the GNRs films on silicon oxide/silicon surfaces, bottom-gated GNR thin-film transistors were fabricated in a solution processed technique.
Computer, multimedia and television (2002)

This paper analyses the architecture features of PCs. Three levels of multimedia definition are proposed. The performances and platform features of PCs and TV for multimedia communication are compared. This results in a proposal of a digital TV (DTV) architecture that retains the good features of a PC but enhances the real-time bit stream processing capability. The key conclusion is that DTV is for entertainment and PCs are for work.
