Fibreoptic intubation using the cuffed oropharyngeal airway and Aintree intubation catheter (1998)

A cuffed oropharyngeal airway has recently been introduced which has larger internal dimensions than a comparable Guedel airway. This allows a ventilation/exchange bougie, the Aintree Intubation Catheter, mounted on a fibreoptic laryngoscope to pass through it. Its 15-mm connector and pharyngeal cuff suggested the possibility of using a Rüsch sealed-port angle piece to allow ventilation through the oropharyngeal airway during fibreoptic laryngoscopy. This study investigated using this equipment to intubate the trachea through the cuffed oropharyngeal airway in paralysed patients, whilst maintaining ventilation manually with a Bain system. In 20 patients, airway control was satisfactory throughout and tracheal intubation was accomplished without complications. The cuffed oropharyngeal airway was easy to manipulate to improve a suboptimal fibreoptic view of the larynx. This may give it an advantage over the laryngeal mask airway when used as a ventilation/intubation conduit.
The plastic human brain (2009)

Taken together, all studies support the view that the human brain is much more plastic than had been anticipated 20 years ago.
An implementation of interprocedural bounded regular section analysis (1991)

Regular section analysis, which summarizes interprocedural side effects on subarrays in a form useful to dependence analysis, while avoiding the complexity of prior solutions, is shown to be a practical addition to a production compiler. Optimizing compilers should produce efficient code even in the presence of high-level language constructs. However, current programming support systems are significantly lacking in their ability to analyze procedure calls. This deficiency complicates parallel programming, because loops with calls can be a significant source of parallelism. The performance of regular section analysis is compared to two benchmarks: the LINPACK library of linear algebra subroutines and the Rice Compiler Evaluation Program Suite (RiCEPS), a set of complete application codes from a variety of scientific disciplines. The experimental results demonstrate that regular section analysis is an effective means of discovering parallelism, given programs written in an appropriately modular programming style.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Impact of Bottleneck Queue Size on TCP Protocols and Its Measurement (2006)

The queue size at a bottleneck would impact the performance of TCP protocols, especially when running a single TCP flow in networks with a large bandwidth-delay product. However, queue size has been not well considered in experiments. This paper shows how bottleneck queue size influences TCP protocols performance. Bursityness of advanced TCPs is examined. Ways of estimating queue size are introduced. Sending a UDP packet train until a loss is detected is a method to measure queuing delay to estimate queue size. Watching a loss in a TCP session to measure round trip time and calculate the queue size is also discussed. Results from experiments with a network emulator and a real network are reported. The results indicated that a layer-2 switch at a congestion point would be a major factor of decreasing TCP performance in a fast long distant path.
Effect of Passage History on Dengue-2 Virus Replication in Subpopulations of Human Leukocytes (1979)

Three passage levels of dengue-2 virus strain PR-159, obtained during the course of deriving the attenuated S-1 vaccine, were tested for their ability to replicate in subpopulations of human peripheral blood leukocytes: (i) 6th primary African green monkey kidney (PGMK) cell passage (parent virus); (ii) 19th PGMK cell passage of a small-plaque-forming clone derived from the parent virus (S-1 PGMK virus); and (iii) virus derived by four additional passages of the S-1 PGMK virus in diploid fetal rhesus lung cells (S-1 vaccine virus). Replication of these PR-159 viruses and another strain of dengue-2 virus adapted to Raji cells (16681-Raji virus) was measured in adherent and nonadherent mononuclear cells. All viruses except the S-1 PGMK virus replicated in monocytes. Occasional replication of the S-1 PGMK virus was associated with reversion to parent virus. The addition to the monocyte cultures of low concentrations of homologous dengue-2 antibody or non-neutralizing heterologous antibody increased the yield of the parent virus as much as 400-fold. This phenomenon of immune enhancement usually enabled the S-1 PGMK virus to replicate slowly in monocytes, but the progeny virus produced large plaques similar to the parent virus. Replication of the S-1 vaccine virus in cultured monocytes did not result in the appearance of large plaques. We could not recover S-1 vaccine virus from monocytes harvested from infected volunteers in the same manner that monocytes from natural human infections yield wild virus. The three passage levels of PR-159 virus were tested for replication in lymphocytes in comparison with the 16681-Raji virus. Only the 16681-Raji virus replicated in human lymphocytes cultured with or without enhancing antibody.
Exploiting Knowledge Management: The Engineering and Construction Perspective (2005)

Construction companies have always relied on their knowledge assets to provide services to clients. In recent years the terminology “knowledge management” has been introduced. Knowledge management (KM) seeks to formalize the manner in which companies exploit their knowledge assets by harnessing organizational knowledge, promoting greater collaboration between groups with similar interests, capturing and using lessons learned on previous projects, etc. This paper investigates how major United States engineering design and construction firms are implementing knowledge management initiatives in order to identify best practice. It adopts a case study methodology to investigate companies’ strategy and implementation, people aspects, and metrics for performance. The study finds that there is a clear distinction between the knowledge management activities undertaken by large engineering design firms and those of construction firms. There is also a much greater emphasis on knowledge sharing, which is just one component of knowledge management. Moreover, some companies have specific KM initiatives while others have activities that are part of their normal business processes.
Key Parameters in the Assessment of Emergency Relief Requirements of Batch and Semi-batch Processes (1990)

The applicability of emergency relief-to batch type reactions in the fine chemical manufacturing industry is discussed. An outline of the key factors which influence the selection of this form of protection is also suggested. Reaction parameters measured using ICI calorimetry are compared to those using DIERS procedures for vapour pressure systems. From case studies, a comparison of DIERS and the former Factory Insurance Association (FIA) vent sizing methods has been made.
Dynamic Foot Pressure and Other Studies as Diagnostic and Management Aids in Diabetic Neuropathy (1983)

The pressures and loads under the feet during walking have been compared in three groups of 41 patients each, using a microprocessor-controlled optical system. Group A consisted of patients with diabetic neuropathy, group B of non-neuropathic diabetic patients, and group C of nondiabetic controls. Thirteen patients in group A had a history of neuropathic foot ulceration. Other investigations in the diabetic patients included motor conduction velocity (MCV) in the median and peroneal nerves, vibration perception threshold (VPT) in the great toes, the valsalva response (VR), skin resistance (SR), and the ankle pressure index (API). Fifty-one percent of neuropathic feet had abnormally high pressures underneath the metatarsal heads compared with 17% of the diabetic controls and 7% of nondiabetic subjects. All those feet with previous ulceration had abnormally high pressures at the ulcer sites. Of the other investigations, the VPT correlated most significantly with the presence of foot ulceration. In addition, a low median and peroneal nerve MCV, an abnormal VR, a high API, and the absence of sweating all correlated with the presence of foot ulceration. We therefore conclude that simple bedside investigations, such as measurement of the VPT alone, may be useful in identifying those patients at risk of foot ulceration. Foot pressure studies may then be used in such patients as a predictive and management aid by determining specific areas under the foot that are prone to ulceration.
A Phenomenological Model for Wind Speed and Shear Stress Profiles in Vegetation Cover Layers (1981)

A phenomenological model for the mean wind speed and Reynolds shear stress profiles with height in a vegetation cover layer is derived from forms suggested by truncation of the equations of turbulent fluid motion at second order in fluctuating velocity products. The initial formulation is unique in that the force per unit volume resisting fluid motion is treated as a body force having a height-dependent character. The body force is assumed to be proportional to the instantaneous speed squared and in the opposite direction from the instantaneous velocity. Viscous forces are ignored as are all pressure forces except for a steady vertical pressure gradient. Closure of the, equations is effected by a phenomenological assumption linking the static pressure and the square of the mean wind speed. The mean wind speed profile predicted by the model is an exponential in the cumulative drag area per unit planform area as a function of height, which is a simple exponential in height for cover with uniform plant area density. Comparisons of predicted profiles of wind speed and Reynolds shear stress with measurements show the model to be relatively robust.
Chemische Wasserstoff‐Aufheizung durch tribride Verbrennung (1967)

Abstract Für zukünftige Raketentriebwerke höchster Leistung wird die Energie aus einer chemischen Umsetzung zwischen einem Metall oder einer Metallverbindung mit einem Oxidator unter gleichzeitiger Beimischung von Wasserstoff gewonnen werden. Dabei nimmt der Wasserstoff, wie die Theorie zeigt, unter optimalen Bedingungen an der Reaktion nicht teil, sondern wird nur aufgeheizt. – Es werden verschiedene derartige Systeme, ihre theoretischen Leistungen sowie ihre Bedeutung für die Weltraumfahrt diskutiert.
Theoretical study of one-photon and two-photon absorption properties of perylene tetracarboxylic derivatives (2008)

The geometrical structure, electronic structure, one-photon absorption (OPA) and two-photon absorption (TPA) properties of the perylene tetracarboxylic derivatives (PTCDs) were studied theoretically by using density functional theory (DFT) and Zerner's intermediate neglect of differential overlap (ZINDO) methods. The results revealed that increasing the number of naphthalene nucleus, extending the conjugated length on long axis, increasing the strength of donor group on lateral side, decreasing the DeltaE(H-L) (energy gap between the highest occupied orbital and the lowest unoccupied orbital) and keeping the conjugation effect and inductive effect along the same molecular axis are the efficient ways to enlarge TPA cross section of PTCDs compounds. The results that PTCDs compounds exhibited extremely large TPA cross section of around 800-1100 nm (near infrared region) shed light into the significance of the PTCDs compounds for applications in TPA labeling materials in vivo.
The<i>IDA/IDA-LIKE</i>and<i>PIP/PIP-LIKE</i>gene families in<i>Arabidopsis</i>: phylogenetic relationship, expression patterns, and transcriptional effect of the PIPL3 peptide (2015)

Peptide ligands play crucial roles in the life cycle of plants by modulating the innate immunity against pathogens and regulating growth and developmental processes. One well-studied example is INFLORESCENCE DEFICIENT IN ABSCISSION (IDA), which controls floral organ abscission and lateral root emergence in Arabidopsis thaliana. IDA belongs to a family of five additional IDA-LIKE (IDL) members that have all been suggested to be involved in regulation of Arabidopsis development. Here we present three novel members of the IDL subfamily and show that two of them are strongly and rapidly induced by different biotic and abiotic stresses. Furthermore, we provide data that the recently identified PAMP-INDUCED SECRETED PEPTIDE (PIP) and PIP-LIKE (PIPL) peptides, which show similarity to the IDL and C-TERMINALLY ENCODED PEPTIDE (CEP) peptides, are not only involved in innate immune response in Arabidopsis but are also induced by abiotic stress. Expression patterns of the IDA/IDL and PIP/PIPL genes were analysed using in silico data, qRT-PCR and GUS promoter lines. Transcriptomic responses to PIPL3 peptide treatment suggested a role in regulation of biotic stress responses and cell wall modification.

Cyclodextrin-Einschlußverbindungen in Forschung und Industrie (1980)

α-, β- und γ-Cyclodextrin sind aus sechs, sieben bzw. acht Glucoseeinheiten bestehende, ringförmige Oligosaccharide, die in großtechnischem Maßstab aus Stärke gewonnen werden können. Sie bilden Einschlußverbindungen mit kleineren Molekülen, die in ihren 5-8 Å weiten Hohlraum hineinpassen. Diese (kristallinen) Komplexe sind für die Forschung interessant, da sie im Gegensatz zu den klassischen Clathraten bereits in wäßriger Lösung existieren und sich an ihnen die in biologischen Systemen so wichtigen hydrophoben Wechselwirkungen studieren lassen. Cyclodextrine dienen außerdem als Modelle für die polymere Stärke und, als kristalline Polyiodid-Komplexe, für die „blaue Iod-Stärke”︁. Da Cyclodextrine mehrere chemische Reaktionen katalysieren, sind sie und ihre Derivate mit funktionellen Gruppen wertvolle Enzymmodelle. Bei der Herstellung von Pharmaka, Schädlingsbekämpfungsmitteln, Nahrungsmitteln und Toilettenartikeln lassen sich Cyclodextrine vorteilhaft verwenden, da die in ihnen eingeschlossenen (mikro-verkapselten) Wirk- und Aromastoffe vor Licht und atmosphärischen Einflüssen geschützt sind und sich in pulverisierter Form leicht handhaben und aufbewahren lassen. In Wasser schlecht lösliche Substanzen werden in Gegenwart von Cyclodextrinen besser löslich, Cremes und Emulsionen können stabilisiert, das Wachstum und der Ernteertrag von Getreide gesteigert werden. Cyclodextrine lassen sich für vielfältige Zwecke chemisch modifizieren; polymerisiertes oder an polymere Träger gebundenes Cyclodextrin wird bereits in der Gelinklusions- und Affinitätschromatographie verwendet.
Fieldbus technology based, distributed control in process industries: a case study with LonWorks Technology (1997)

During recent years, in the field of real‐time instrumentation and process control, there has been a trend away from centralized control system. Distributed control by using fieldbus technology is only the first step to application of intelligence in the field devices. Compares centralized systems with the distributed systems, differentiates the conventional LANs from the fieldbus technology and reviews the related technology and the current status of the international fieldbus standards. Describes some of the standard fieldbuses. Highlights the advantages of using fieldbuses in the real‐time process control and discusses what are the points to be considered before selecting a fieldbus. Highlights fieldbus‐based design development methodology involved in order to build a real‐time industrial distributed control system (RIDCS). Presents a case study with the LonWorks Technology; a fieldbus category system.
Coupled Membranes with Doubly Negative Mass Density and Bulk Modulus (2013)

We present a structurally and conceptually simple acoustic double negative metamaterial comprising two coupled membranes. Owing to its symmetry, the system can generate both monopolar and dipolar resonances that are separately tunable, thereby making broadband double negativity possible. A homogenization scheme is implemented that enables the exact characterization of our metamaterial by the effective mass density and bulk modulus even beyond the usual long-wavelength regime, with the measured displacement fields on the sample's surfaces as inputs. Double negativity is achieved in the frequency range of 520-830 Hz. Transmission and reflection predictions using effective parameters are shown to agree remarkably well with the experiment.
A rainfall intensity gauge (1961)

An experimental raingauge is being tried out by the Christchurch Drainage Board to measure the intensity of the rainfall without the necessity of using a recording instrument with the inherent daily attendance for the changing of charts. The aim is to have an instrument requiring infrequent attention - only after rain - and the ability of this gauge to perform without attention is now being tested.
Role of Insulin in the Regulation of Protein Synthesis (1980)

Recent research has established an anabolic role for insulin in the regulation of protein turnover, and in some instances identified specific reactions as the site of hormone action. Two major control mechanisms have been implicated, one in muscle tissue and one in liver. The major advances in recent years have included vastly greater knowledge of the chemical reactions in the pathway of protein synthesis; new methods for accurate measurements of synthetic rates; procedures for in vitro perfusion of liver, heart, and skeletal muscle; methods for measurement of intermediates in the synthetic pathway; methods for quantifying the synthesis of individual proteins; and techniques for measuring messenger RNA levels for specific proteins. Future work is dependent on further definition and characterization of the individual components of the synthetic pathway
Synthesis and <i>in vitro</i> evaluation of some new pyrimidines and related condensed ring systems as potential anticancer agents (1996)

Ring-resonator-integrated tunable external cavity laser employing EAM and SOA (2011)

We propose and demonstrate a tunable external cavity laser (ECL) composed of a polymer Bragg reflector (PBR) and integrated gain chip with gain, a ring resonator, an electro-absorption modulator (EAM), and a semiconductor optical amplifier (SOA). The cavity of the laser is composed of the PBR, gain, and ring resonator. The ring resonator reflects the predetermined wavelengths into the gain region and transmits the output signal into integrated devices such as the EAM and SOA. The output wavelength of the tunable laser is discretely tuned in steps of about 0.8 nm through the thermal-optic effect of the PBR and predetermined mode spacing of the ring resonator.
Adaptive field oriented control of induction motors (1997)

In systems without converters for measuring the stator voltages, only reduced order observers based on the current equations are seen. Full order rotor flux observers are not applicable because stator voltage measurements are used. This problem is in this paper managed by an adaptive approach leading to a completely new method called Field Angle Adaptation (FAA). The new contribution to the conventional current control system in rotor field oriented dq-coordinates is a signal added to the field angle in the transformation from rotor field coordinates to stator fixed coordinates. This signal adapts the field angle estimate to the correct rotor field angle.

RZ current switches are added to a current steering DAC for high-frequency wideband applications to achieve 800MHz bandwidth at 1/sup st/ and 2/sup nd/ Nyquist band without the need for a reverse sinc equalization filter. Implemented in a GaAs HBT process with 4.5 /spl mu/m/sup 2/ minimum emitter area, the DAC dissipates 1.2W at -5V with a 1.6GHz clock and 0dBm typical output power.
Electronically tunable simple oscillator based on single-output and multiple-output transconductor (2009)

The electronically tunable oscillator with a single-output and a multiple-output transconductor and with three passive grounded elements is presented and verified in this paper. The active elements are modeled on the transistor level for the possibility to implement the whole oscillator on chip. The characteristic equation and condition for oscillation are discussed together with the major influence of the parasitic properties of the active devices. Using the proposed concept an experimental verification employing two commercially available transconductance amplifiers is given via associated time-domain and frequency-domain results.

COPLANAR WAVEGUIDES INCORPORATING SRRS OR CSRRS (2014)

Abstract—We numerically and experimentally evaluate different designs of coplanar waveguides (CPWs) loaded with split ring resonators (SRRs) and complementary split ring resonators (CSRRs), respectively. In particular, we are interested in their stop-band performance. Starting from structures which consist of two concentric rings, we study devices with only an outer ring, an inner ring or multiple concentric rings. Furthermore, our study shows that introducing slots in the proximity of the SRR or CSRR will modify the stop-band considerably. Single and multiple unit cells for both designs are fabricated and measured. Our results demonstrate the potential of the CSRR/CPW structure for filter applications. 1.

INTEGRIN EXPRESSION BY HUMAN ARTICULAR CHONDROCYTES (1992)

Expression of integrins, a family of cell adhesion proteins, by human articular cartilage chondrocytes in vivo has been studied by immunohistological techniques using cryostat sections and a panel of anti-integrin monoclonal antibodies. Chondrocytes strongly expressed beta 1 and alpha 5 integrin subunits, known to form the classical fibronectin receptor, VLA-5, strongly. alpha 1 was expressed more weakly and variably; alpha 3 was expressed by occasional cells only. Chondrocytes did not express beta 2, beta 3 or other integrin alpha subunits tested.
