Mittlere Ringe, IX. Weiteres zur Sterischen Mesomeriehinderung in 1.2‐Benzo‐Cyclen‐(1)‐Onen‐(3) (1957)

Abstract Die intramolekulare Friedel‐Crafts‐Acylierung der ω‐Phenyl‐fettsäure‐chloride in hoher Verdünnung gestattet auch die Schließung des 9‐ und evtl. des 10‐gliedrigen Ringes, wenn man Aluminiumbromid als Kondensations‐mittel verwendet. Daneben werden mehrere Methylabkömmlinge des 1.2‐Benzo‐cycloocten‐(1)‐ons‐(3) bereitet. An den UV‐Spektren all dieser Ringketone wird das Zusammenspiel von Mittlerer‐Ring‐Torsion und Konjugationskraft diskutiert. Die Oszillatorenstärken ermöglichen eine Abschätzung des Torsions‐winkels in den mesomeriegehinderten Systemen.
Assessment of a 35% Fluorocarbon Emulsion (1983)

We have previously reported on the efficacy of a 20% fluorocarbon emulsion (Fluosol-DA, 20%) as an acellular O2 carrier at an FIO2 = 1.0. We are concerned, however, about the potential O2 toxicity that may result from extended exposure to FIO2 = 1.0. The O2 content of the fluorocarbon phase is linearly related to both the FIO2 and the fluorocarbon concentration (Fct). It should therefore be possible to maintain the same O2 content by raising the Fct using a higher fluorocarbon concentration and lowering the FIO2. The purpose of this report is to assess the ability of a 35% fluorocarbon emulsion (Fluosol-DA, 35%) at an FIO2 = 0.6 to support hemodynamics and O2 transport. Five adult baboons were paralyzed, anesthetized, intubated, and mechanically ventilated at FIO2 = 0.6. An isovolemic total exchange transfusion (E.T.) with Fluosol-DA, 35% was performed. Measurements were made at Hct's of 20, 10, 5, and less than 2%. All animals survived the exchange. Total arterial O2 content fell from 17.4 +/- 0.7 to 3.3 +/- 0.2 vol% (p less than 0.01), and O2 delivery decreased from 21.8 +/- 2.2 to 5.1 +/- 0.7 cc/min-kg (p less than 0.01) during the exchange. There was no significant change in MAP, H.R., C.O., or VO2 during the exchange transfusion. Fluosol-DA, 35% maintains normal hemodynamics and O2 transport despite a marked fall in arterial O2 content and total O2 delivery. Fluosol-DA, 35% is thus an effective O2 carrier at the safe FIO2 of 0.6.
Effect of extracorporeal CO2 removal on respiratory rate in spontaneously breathing patients with chronic obstructive pulmonary disease exacerbation (2013)

During severe exacerbation of chronic obstructive pulmonary disease (COPD) tachypnea, as a consequence of respiratory acidosis, and airflow limitation, due to small airway obstruction, lead to lung hyperinflation, respiratory distress and gas exchange impairment. Invasive mechanical ventilation could worsen lung hyperinflation and produce a vicious circle. We investigated whether increasing extracorporeal carbon dioxide removal (ECCO2 Cl) could reduce the respiratory rate (RR), so prolonging time for lung emptying and allowing resolution of hyperinflation.
<i>Plasmodium falciparum</i>pre-erythrocytic vaccines: previous experience and the challenge of selecting new candidates (2014)

A highly effective pre-erythrocytic malaria vaccine would meet all public health objectives, preventing disease in the recipient by eliminating the infection prior to the pathogenic blood stages and preventing transmission back to the mosquito vector.
Combined high oxytocic with negligible antidiuretic and pressor activities in multisubstituted oxytocins (1977)

Oxytocin analogues which combine high oxytocic activities with negligible antidiuretic and pressor activities have been studied. [4-Threonine,7-glycine]oxytocin, [1-(L-2-hydroxy-3-mercaptopropionic acid),4-threonine,7-glycine]oxytocin, and [1-(L-2-hydroxy-3-mercaptopropionic acid)]oxytocin were found to possess the following specific biological activities respectively: rat uterotonic, 270 +/- 10, 337 +/- 23, 1542 +/- 0.4; rat antidiuretic, 0.002 +/- 0.0008, 0.048 +/- 0.005, 40.3 +/- 2.4. The results are analyzed from a conformation-activity viewpoint in a continued attempt to evaluate the scope and limitations of this approach in comparison to structure-activity studies.
Circuit speed timing jitter increase in random logic operation after NBTI stress (2014)

Recently, much effort has been spent trying to relate NBTI observations to real circuit impacts. While many of these efforts rely on circuit simulation to bridge this gap, an experimental approach is, of course, preferred. In this study we provide this experimental solution in the form of eye-diagram measurements to quantify NBTI-induced changes in timing jitter. We investigate these NBTI-induced jitter increases using a variety of ring-oscillator as well as pseudo-random gate patterns. The pseudo-random gate pattern is a close approximation to real world random logic. We observe that the NBTI-induced jitter increase depends strongly on the chosen gate pattern and is most severe for the pseudo-random case. These observations strongly suggest that more regular gate pattern (ring-oscillator) measurements underestimate the circuit impact of NBTI.
Design and implementation of real-time distributed systems with the ASSERT Virtual Machine (2010)

This paper describes how the ASSERT Virtual Machine, a dedicated execution platform that guarantees a predictable real-time behaviour, can be used to develop real-time embedded distributed systems with high-integrity requirements. The concept of virtual machine-level software components is developed, and sample programming patterns are provided. Components are used in the framework of the ASSERT development process, and are based on the Ravenscar Computational Model, a concurrent tasking model which can be statically analysed for a correct real-time behaviour. The current architecture of the ASSERT virtual machine is described in detail, and experience gained with its use in the last few years is provided.
The correlation of urodynamic findings with cranial magnetic resonance imaging findings in multiple sclerosis. (1998)

Although patients with multiple sclerosis often are followed closely with urodynamic studies and cranial MRI, there appears to be no correlation between these 2 studies. Symptom scores also do not appear to correlate with urodynamic findings. Therefore, urodynamic studies appear to be warranted and irreplaceable in the evaluation of voiding dysfunction in multiple sclerosis patients.
Imaging of the guinea pig cochlea following round window gadolinium application (2004)

Precise, non-invasive determination of the aetiology and site of pathology of inner ear disorders is difficult. The aim of this study was to describe an alternative method for inner ear visualization, based on local application of the paramagnetic contrast agent gadolinium. Using a 4.7 T MRI scanner, high contrast images of all four cochlear turns were obtained 3.5 h after placing gadolinium on the round window membrane. Gadolinium cleared from the cochlea within 96 h. Auditory brainstem response measurements performed on a separate group of animals showed no significant threshold shifts after the application, indicating that gadolinium is non-toxic to the guinea pig cochlea.

We report a case of pneumonia due to Torulopsis glabrata in a patient of 58 years in complete remission from a malignant oesophageal tumour after surgery and radiotherapy, and not given immunosuppressive treatment.
Investigating How Automatic Disclosure of Partners' Location Influences Mobile Coordination (2006)

This paper reports on results from a field experiment using a pervasive game that aims at eliciting the influence of location-awareness of others in a mobile and collaborative task. We present the environment as well as first results concerning how different automatic disclosure of partnersâ positions undermined communication and coordination processes.
ADRENOCORTICOTROPIC HORMONE (1943)

Of six hormones' identified in the ant.erior hypophysis, the adrenocorticotropic hormone is least known.Since the observation of Smith (6), only five publications have appeared (7-11) which give methods that may be used to secure a solution concentrated in adrenocorticotropic activity.No agreement is found among these workers as to the chemical nature of the hormone.In order to establish the biological characteristic of a hormone from a complex source such as the pituitary, it must first be isolated in pure form judged both by chemical and biological data.The present paper presents a method2 for the isolation of the adrenocorticotropic hormone which is freed from other active contaminants, and behaves chemically as a single substance. Method of Isolation
Performance Improvement of Ring-Type PZT Ceramics for Ultrasonic Dispersion System (2020)

This study has been based on the examination of the characterization of ring-type lead zirconate titanate (PZT) ceramics for high-intensity focused ultrasonic dispersion system. The ring-type PZT ceramics were fabricated by the powder molding method. The mechanical properties, dielectric constant, and microstructure of the ceramics were investigated. Consequently, the density of the ceramics was increased with increasing forming pressure while the density of ceramics that were sintered at 1350 °C was decreased due to over-sintering. Furthermore, the mechanical properties were excellent at the higher forming pressure. The dielectric property of the ring-type PZT ceramics was not clearly influenced by the manufacturing and sintering conditions. The abnormal grain growth of the ceramics, however, could be prevented by a lower heating rate in addition to reducing the porosity.
Sol–gel derived hybrid materials as heterogeneous catalysts for the synthesis of N,N-dimethylformamide from supercritical carbon dioxide (1996)

Hybrid materials derived from group VIII metal–chloro complexes of the type MCl2X2(M = Pt, Pd), MClX3(M = Rh, Ir) and especially RuCl2X3[X = Ph2P(CH2)2Si(OEt)3, Me2P(CH2)2Si(OEt)3] by cocondensation with Si(OEt)4via a sol–gel process are highly active heterogeneous catalysts for the synthesis of N,N-dimethylformamide (dmf) from CO2, H2 and dimethylamine under supercritical conditions, affording turnover numbers up to 110 800 at 100% selectivity.
A Novel Surface Reconstruction and Display Method for Cardiac PET Imaging (1984)

Positron emission tomography (PET) allows the in vivo assessment of biochemical activity in humans. The newer PET cameras can create several imaging planes, or slices, through an organ inside the body. The interpretation of two-dimensional (2-D) slices of an organ is often difficult for the clinician since he or she has to form a three-dimensional (3-D) mental composite of the structure of interest. We have developed a set of algorithms to reconstruct a functional three-dimensional surface model of the cardiac left ventricle from a set of two-dimensional cross-sectional image slices generated by PET. The theoretical techniques for this reconstruction method are applicable to most organs provided that the appropriate models for the organs are considered. An automatic boundary detection algorithm outlines the surface of the left ventricle from the 2-D images and assigns intensity values to the surface points whose level is proportional to the local activity. A 3-D surface of the intensity levels, with pseudocolor enhancement, is then displayed with the long axis of the heart in a vertical position. Such a display allows the 3-D myocardial tracer uptake to be clearly visualized by the clinician for better diagnosis.

Indirect adaptive control of spatially invariant systems (2010)

We present a general class of indirect adaptive controllers for spatiotemporally invariant systems. The control design is based on certainty-equivalence approach, where at each step system parameters are estimated and the controller is implemented using the estimated parameters. At each estimation stage a modeling error is committed which affects the output of the plant. We show that under suitable assumptions on the rates of variation of the estimated plant, which follow from utilizing a distributed projection algorithm, a globally stable adaptive scheme can be guaranteed.
[Computer method for fusional reserves evaluation with objective control of fusion break]. (2010)

A method of assessing fusional reserves using an interactive computer program, which allows to monitor the subjects report on the moment of fusion break with artificial increase of convergence or divergence of the vii sual axes in the measurement process was developed and tested. Control is achieved through the use of a purely binocular stimuli--random-dot stereograms, as well as dynamic markers, which are added to the main test object in a random order in the course of the measurement procedure to change the type of test-object. Test-object with a marker, encoded in the stereogram, is seen only at the expense of binocular mechanisms, and in violation ofifusion is no longer visible. Its disappearance helps the subject to determine when failure of fu-sion occurred, and the type of object with a marker before this point allows the experimenter to check the subject. Statistical analysis of primary and repeated measurements of fusion reserves in 72 subjects confimed the sufficient reliability of the method.
Energy-Efficient MIMO-OFDMA Systems Based on Switching off RF Chains (2011)

In this paper, both configuration of active radio frequency (RF) chains and resource allocation are investigated for improving energy efficiency of downlink multiple-input-multiple-output (MIMO) orthogonal frequency division multiple access (OFDMA) systems. We first formulate an optimization problem to minimize the total power consumed at the base station with the maximum transmit power constraint and ergodic capacity constraints from multiple users. Then a two-step suboptimal algorithm is proposed. Specifically, the continuous variable optimization problem is first solved, and then a discretization algorithm is presented to obtain the number of active RF chains and the number of subcarriers allocated to each user. Simulation results demonstrate that the proposed algorithm can provide significant power-saving gain over the all-on RF chain scheme and the adaptive subcarrier allocation helps to save more power.
Design and performance of 800MHz/2GHz dual band small planar antenna (2009)

We designed and fabricated electrically small antenna (ESA) with a coplanar transmission line-based matching circuit on a printed circuit board. The matching circuit is realized by applying band-pass filter (BPF). Moreover, we designed a dual band antenna by connecting two ESAs with BPF-based duplexer. Our proposed dual band antenna is designed and simulated by using commercial three-dimensional electro magnetic (EM) field simulator. Also, we fabricated this dual band antenna on FR4 substrate and measured the frequency characteristics.
Surface plasmon resonance using the catalytic domain of soluble guanylate cyclase allows the detection of enzyme activators (2014)

Soluble Guanylate Cyclase (sGC) is the receptor for the signalling agent nitric oxide (NO) and catalyses the production of the second messenger cyclic guanosine monophosphate (cGMP) from guanosine triphosphate (GTP). The enzyme is an attractive drug target for small molecules that act in the cardiovascular and pulmonary systems, and has also shown to be a potential target in neurological disorders. We have discovered that 5-(indazol-3-yl)-1,2,4-oxadiazoles activate the enzyme in the absence of added NO and shown they bind to the catalytic domain of the enzyme after development of a surface plasmon resonance assay that allows the biophysical detection of intrinsic binding of ligands to the full length sGC and to a construct of the catalytic domain.
A wideband IM3 cancellation technique for CMOS attenuators (2012)

In the receiver path and in spectrum analyzers, typically gain control blocks are used to limit the incident power to the level that the receiver circuitry can handle without degrading the linearity; in the transmitter path stringent power control is also desirable. Although variable-gain amplifiers (VGAs) traditionally implement the gain-control block, attenuators based on FET transistors show superior performances on linearity, power handling capability and power consumption.
Haploinsufficiency of the NOTCH1 Receptor as a Cause of Adams–Oliver Syndrome With Variable Cardiac Anomalies (2015)

These findings highlight a key role for NOTCH1 across a range of developmental anomalies that include cardiac defects and implicate NOTCH1 haploinsufficiency as a likely molecular mechanism for this group of disorders.
Influence of nanoparticle coolant and crystal structure of the workpiece during nanometric cutting of silicon carbide (2012)

Silicon carbide (SiC) is a suitable candidate for MEMS, NEMS, optoelectronic andnanotribological applications e.g. airborne laser devices, laser radar systems, vacuumultraviolet (VUV) telescopes and space based laser mirrors. In-depth understanding of the influence of coolant and crystal structure of the work material on the nanometric cutting process of SiC could help in cost saving operations. Therefore, nanoscratching trials were carried out on single crystal 6H-SiC involving four pre-selected coolants to emulate nanometric cutting. A specific coolant was found to improve the cutting conditions tremendously and hence recommended. Moreover, a molecular dynamics (MD) simulation model was developed to simulate nanometric cutting of polycrystalline (PC) 3C-SiC and single crystal (SC) 3C-SiC. Besides explaining the reasons for the ease of machinability of chemically vapour deposited (CVD) 3C-SiC compared to SC-3C-SiC, simulation results also explains why SC-SiC provides a better measure of attainable surface roughness in comparison to CVD-SiC and reaction bonded (RB)-SiC.
General equation of stress-strain behavior in crystalline polymers (1975)

Crystalline polymers show a remarkable strain hardening in its plastic deformation compared with metals. In the case of metals, the power law holds between true stress and true strain, the power law index of which is lower than one (1). True stress tends to saturate with increasing true strain. Polymer chain shows very high modulus and high bonding energy along molecular axis, whereas intermolecular force is weak and the modulus perpendicular to the molecular axis is about one hundredth of that along molecular axis. With the progress of unfolding of molecular chains from folded structure in lamellar crystals, the deformation stress increases rapidly. To describe such a deformation process of crystalline polymers, it is especially necessary to employ true stress and true strain instead of nominal stress and nominal strain. In our previous paper (2), we have presented the equation to describe the true stress-strain relationship in a very simplified form, which was verified for linear polyethylene (HDPE) and nylon 6. In this paper, we have examined the applicability of our equation to isotactic polypropylene (PP), polyoxymethylene (POM) and polytetrafluoroethylene (PTFE).
Selective leaching process for the recovery of copper and zinc oxide from copper-containing dust (2014)

The purpose of this study was to develop a resource recovery procedure for recovering copper and zinc from dust produced by copper smelting furnaces during the manufacturing of copper-alloy wires. The concentrations of copper in copper-containing dust do not meet the regulation standards defined by the Taiwan Environmental Protection Administration; therefore, such waste is classified as hazardous. In this study, the percentages of zinc and copper in the dust samples were approximately 38.4% and 2.6%, respectively. To reduce environmental damage and recover metal resources for industrial reuse, acid leaching was used to recover metals from these inorganic wastes. In the first stage, 2 N of sulphuric acid was used to leach the dust, with pH values controlled at 2.0-3.0, and a solid-to-liquid ratio of 1:10. The results indicated that zinc extraction efficiency was higher than 95%. A selective acid leaching process was then used to recover the copper content of the residue after filtration. In the second stage, an additional 1 N of sulphuric acid was added to the suspension in the selective leaching process, and the pH value was controlled at 1.5-2.0. The reagent sodium hydroxide (2 N) was used as leachate at a pH greater than 7. A zinc hydroxide compound formed during the process and was recovered after drying. The yields for zinc and copper were 86.9-93.5% and 97.0-98.9%, respectively.
A Study on Full and Part Load Operations of a Biogas-fired Gas Turbine Combined Heat and Power System (2011)

This study analyzed the influence of firing biogas on the performance and operation of a gas turbine combined heat and power (CHP) system. A reference CHP system designed with natural gas fuel was set up and off-design simulation was made to investigate the impact of firing biogas in the system. Changes in critical operating parameters such as compressor surge margin and turbine blade temperature caused by firing biogas were examined, and a couple of operating schemes to mitigate their changes were simulated. Part load operation of the biogas-fired system was compared with that of natural-gas fired system, and it was found that as long as the two system produce the same electric power output, they exhibit nearly the same heat recovery.
