Immunisation strategies for Antibody Production (2008)

A range of immunisation techniques can be used for the successful production of antibodies. The choice of method used is dependent on the nature of the antigen and the type of antibody required by the user.
A Cold Shock-Induced Cyanobacterial RNA Helicase (1999)

The ability to modify RNA secondary structure is crucial for numerous cellular processes. We have characterized two RNA helicase genes, crhB and crhC, which are differentially expressed in the cyanobacterium Anabaena sp. strain PCC 7120. crhC transcription is limited specifically to cold shock conditions while crhB is expressed under a variety of conditions, including enhanced expression in the cold. This implies that both RNA helicases are involved in the cold acclimation process in cyanobacteria; however, they presumably perform different roles in this adaptation. Although both CrhB and CrhC belong to the DEAD box subfamily of RNA helicases, CrhC encodes a novel RNA helicase, as the highly conserved SAT motif is modified to FAT. This alteration may affect CrhC function and its association with specific RNA targets and/or accessory proteins, interactions required for cold acclimation. Primer extension and analysis of the 5' untranslated region of crhC revealed the transcriptional start site, as well as a number of putative cold shock-responsive elements. The potential role(s) performed by RNA helicases in the acclimation of cyanobacteria to cold shock is discussed.
Integrated Water and Waste Management System for Future Spacecraft (1975)

Over 200 days of continuous testing have been completed on an integrated waste management-water recovery system developed by General Electric under a jointly funded AEC/NASA/AF Contract. The 4 man system provides urine, feces, and trash collection; water reclamation; storage, heating and dispensing of the water; storage and disposal of the feces and urine residue and all of other nonmetallic waste material by incineration. The heat required for the 1200 deg F purification processes is provided by a single 420-w radioisotope heater. A second 836-w radioisotope heater supplemented by 720 w of electrical heat provides for distillation and water heating. Significant test results are no pre-or-post treatment, greater than 98 percent potable water recovery, approximately 95 percent reduction in solids weight and volume, all outflows are sterile with the water having no bacteria or virus, and the radioisotope capsule radiation level is only 7.9 mrem/hr unshielded at 1 m (neutrons and gamma).

Colorimetry and constant-potential coulometry determinations of transferrin-bound iron, total iron-binding capacity, and total iron in serum containing iron-dextran, with use of sodium dithionite and alumina columns. (1990)

After the parenteral administration of iron-dextran (imferon), the increased total iron concentrations in serum can be determined by atomic absorption spectroscopy and by colorimetric methods involving sodium dithionite, which reductively dissociates iron from the dextran complex. We report that constant-potential coulometry detects only about 55-70% of dextran-bound iron before dithionite reduction and variable amounts after reaction with the reducing agent. In addition, we have developed a procedure for determining transferrin-bound iron, total iron-binding capacity (TIBC), total iron, and dextran-bound iron with the Kodak Ektachem colorimetric system. In determining total serum iron, the sample is first mixed with sodium dithionite, which rapidly dissociates all dextran-bound iron, but does not remove iron from either transferrin or hemoglobin. After the mixture is applied to an Ektachem slide, transferrin-bound iron is released at pH 4 and is detected together with the iron previously bound to dextran. TIBC is determined by mixing serum with ferric citrate in moderate excess and filtering through a small alumina (Al2O3) column, which binds excess free iron and iron-dextran; the iron in the column eluate represents the TIBC. Transferrin-bound iron is determined by applying diluted serum without added ferric citrate to an alumina column and measuring the iron in the column eluate. Dextran-bound iron is equivalent to the difference between total and transferrin-bound iron. Using this method, we found that transferrin iron-binding sites are saturated in vitro by excess iron-dextran less efficiently than by ferric citrate.
The Diarylquinoline R207910 Is Bactericidal against <i>Mycobacterium leprae</i> in Mice at Low Dose and Administered Intermittently (2009)

The diarylquinoline R207910 is profoundly bactericidal in a murine model of tuberculosis. Previously, R207910 was also found to be bactericidal for Mycobacterium leprae-infected mice during lag phase. Herein we evaluate the bactericidal efficacy of R207910 (1 to 120 mg/kg of body weight) when administered five times weekly, once weekly, and once monthly during logarithmic multiplication of M. leprae organisms. All treatments were found to be bactericidal, suggesting that both low and intermittent dosing with R207910 holds promise for leprosy patients.
A Rabbit Model of Peripheral Compartment Syndrome with Associated Rhabdomyolysis and a Regenerative Medicine Approach for Treatment (2011)

Peripheral compartment syndrome (PCS) has a complex etiology, with limited treatment options and high patient morbidity. Animal models of PCS have been hampered by differences in cross-species anatomy, physiology, and the relative rarity of the naturally occurring syndrome in animals. In the present study, the combination of saline infusion with intermittent crushing of skeletal muscle consistently caused increased intracompartmental pressure, hypocalemia, and hypercreatinine-phophokinasemia, signs diagnostic of PCS. This method was used to evaluate both the standard PCS treatment, specifically a fasciotomy, and a regenerative medicine approach for treatment-consisting of a fasciotomy with local administration of a biologic scaffold material composed of porcine small intestinal submucosa extracellular matrix (SIS-ECM). The use of this SIS-ECM scaffold in conjunction with a fasciotomy was associated with myogenesis and constructive tissue remodeling in the SIS-ECM-treated animals. At 1 and 3 months after treatment innervated muscle tissue was present at the site of injury. No myogenesis was present in the fasciotomy only treated animals. RAM11+ macrophages, which are associated with constructive tissue remodeling, were present within the injury site in the SIS-ECM-treated animals at 1 month. The present study provides a reproducible animal model with which to study PCS, and shows the potential of a regenerative medicine approach to PCS treatment.
Percutaneous transluminal coronary angioplasty: A review of current balloon dilatation systems (1989)

The interventional cardiologist is faced with an expanding armamentarium for performing percutaneous transluminal coronary angioplasty (PTCA). Because of rapid advances in technology, new devices are produced on a regular basis, making it difficult to maintain a working knowledge of what is available. Although several excellent textbooks about PTCA have been written, descriptions of available equipment are usually obsolete by the time publication occurs. In order to provide succinct specifications of equipment, we have documented data on balloon catheters, guiding catheters, and guidewires. This information may be useful in the selection of appropriate equipment for PTCA procedures. In addition, the publication of such data in a monthly periodical may provide a more current overview of equipment; information may be occasionally updated as new equipment is released.

Flight-simulation tests on notched elements (1974)

Tests were carried out on open-hole specimens, lugs and riveted strap joints of 2024-T3 and 7075-T6 materials. The effects of design stress level, truncating high-amplitude gust loads and omitting low-amplitude gust cycles were stuaied. Observations of the open-hole specimens include data on crack initiation, crack closure and damage increments. Constant-amplitude tests were also carried out on the lugs and damage calculations were made. The discussion of the results includes an analysis of the trends observed and the significance of the data for practical problems
Carrier lifetime versus ion-implantation dose in silicon on sapphire (1987)

We have measured the dependence of the free-carrier lifetime on O+ ion-implantation dose in silicon-on-sapphire. At low implant doses, the carrier trapping rate increased linearly with the trap density introduced by ion implantation. At doses above 3×1014 cm−2 the measured carrier lifetime reached a limit of 600 fs.
Roboticizing fabric by integrating functional fibers (2020)

Fabrics are ubiquitous materials that have conventionally been passive assemblies of interlacing, inactive fibers. However, the recent emergence of active fibers with actuation, sensing, and structural capabilities provides the opportunity to impart robotic function into fabric substrates. Here we present an implementation of robotic fabrics by integrating functional fibers into conventional fabrics using typical textile manufacturing techniques. We introduce a set of actuating and variable-stiffness fibers, as well as printable in-fabric sensors, which allows for robotic closed-loop control of everyday fabrics while remaining lightweight and maintaining breathability. Finally, we demonstrate the utility of robotic fabrics through their application to an active wearable tourniquet, a transforming and load-bearing deployable structure, and an untethered, self-stowing airfoil.
Proof of Concept for Recombinant Cellular Controls in Quantitative Molecular Pathogen Detection (2011)

In this study, we present the concept of internal sample process controls (ISPCs) to monitor the efficiency of an analytical chain using sample preparation and quantitative PCR (qPCR). A recombinant Listeria monocytogenes ΔprfA (targeted deletion) strain containing a competitive artificial single-copy genomic target was applied to naturally contaminated samples to demonstrate its analytical suitability as an ISPC.
Developing Affective Lexical Resources (2004)

Affective computing is advancing as a field that allows a new form of human computer interaction, in addition to the use of natural language. There is a wide perception that the future of human-computer interaction is in themes such as entertainment, emotions, aesthetic pleasure, motivation, attention, engagement, etc. Studying the relation between natural language and affective information and dealing with its computational treatment is becoming crucial. In this paper we present a linguistic resource for a lexical representation of affective knowledge. This resource (named WORDNET-AFFECT) was developed starting from WORDNET, through the selection and labeling of the synsets representing affective concepts.
Performance of a hybrid multilevel error control with an early-stop ARQ protocol for wireless ATM networks (2003)

This paper proposes an effective hybrid multilevel error control (HMEC) with an early-stop automatic repeat request (ARQ) scheme for wireless asynchronous transfer mode (ATM) networks. In this scheme, the source traffic is segmented into a number of blocks, each with m cells, then encoded into k(k>m) cells. The transmission of one block may be finished as long as m out of the k cells are received correctly. The ARQ protocol is applied only when too many cells are dropped or corrupted due to uncorrectable error in the radio channel. This paper also provides a detail study of the proposed scheme. In particular, the throughput efficiency with parameters (m,k) are derived analytically for the white Gaussian and Rayleigh fading channels. Simulation results show a very close match with theoretical results. All the results show that the HMEC scheme can reduce cell-retransmission probability and improve network throughput over a wide range of channel error rates when appropriate values of parameters m and k are chosen.
Digital MF Receiver Using Discrete Fourier Transform (1973)

In a digital toll switching office a digital multifrequency (MF) receiver may be more economical than the present analog MF receiver. This paper suggests an algorithm that could be used for digital implementation of such a receiver. The algorithm employs discrete Fourier transform and leads to more efficient design than a system using second-order digital bandpass filters. The presented results of computer simulation of the digital MF receiver employing this method indicate satisfactory performance and good immunity to random noise interference.
Über aktivierte Ester. I. Aktivierte Ester der Hippursäure und ihre Umsetzungen mit Benzylamin (1955)

Abstract Introduction of electron‐attracting substituents into the alcoholic component of methyl‐hippurate leads to activated esters which are characteristic acylating agents. A number of activated esters of hippuric acid are compared. The best acylating agent seems to be the cyanomethylester which is an easily accessible, cristalline, and stable compound, reacting easily with benzylamine at room temperature.
Magnetorheological fluid composites synthesized for helicopter landing gear applications (2013)

Magnetorheological fluid composites were formulated in this study to investigate their performance for potential use in landing gear hydraulic systems, such as shock struts. The magnetorheological fluids synthesized here utilized three hydraulic oils certified for use in landing gear, two average diameters of spherical magnetic particles, and a lecithin surfactant. The magnetorheology of these fluids was characterized, including (a) magnetorheology (yield stress and viscosity) as a function of magnetic field, (b) sedimentation analysis using an inductance-based sensor, (c) cycling of a small-scale magnetorheological damper undergoing sinusoidal excitations at frequencies of 2.5 and 5 Hz, and (d) impact testing of an magnetorheological damper for a range of magnetic field strengths and velocities using a free-flight drop tower facility. The goal of this research is to analyze the performance of these magnetorheological fluid composites, compare their behavior to standard commercial magnetorheological fluid, and determine their feasibility for use in helicopter landing gear.
An error analysis for surface orientation from vanishing points (1990)

Given two parallel lines in a plane, their images formed by central projection onto the viewing plane intersect at a vanishing point, which provides a constraint on the orientation of the plane. Two such independent constraints define a vanishing line and thereby determine the orientation of the plane uniquely. In order to effectively use this information, an estimate of its accuracy must be incorporated. In the approach suggested, line directions and surface normal vectors are represented as points on a Gaussian sphere, and the error bounds are computed as regions on the sphere. Information from multiple vanishing points and surfaces is combined by intersecting the corresponding regions. In addition, constraints based on real-world knowledge can be introduced to improve the accuracy. Some experimental results on natural images re presented to illustrate this method.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
