Some Complexation Reactions of Cellulosic Ethers (1972)

Abstract Cellulose ethers were prepared by the reaction of sodium cellulosate with 1-chloromethylnaphthalene, 2-bromomethyl-pyridine, 2-chloropyridine, crotyl bromide, propargyl chloride, and 1-naphthyl glycidyl ether and their complexation ability was investigated. No π-complex formation with picric acid or 2,4,6-trinitrobenzene took place. Results were attributed to steric hindrance from the cellulosic backbone. Complexation of some metal salts by the crotyl and propargyl ethers was investigated. Good results were obtained with mercuric chloride, aluminum chloride, and silver nitrate when propargyl cellulose was used.
Service unit management and nurses' satisfaction. (1976)

Nurses' satisfaction was compared in 55 patient units, 32 with service unit management (SUM) and 23 without. Satisfaction of licensed practical nurses was unrelated to SUM, but intrinsic task satisfaction of registered nurses (and of head nurses, who were considered separately) was positively related to the presence of SUM. Transfer of nonprofessional tasks out of nursing and reduction of tension arising from reduced responsibility of nurses for coordinating activities with ancillary departments are possible explanations for the positive relation between the presence of SUM and professional nurses' satisfaction.
Tn10/IS10 transposase purification, activation, and in vitro reaction. (1994)

We describe a method for the purification of Tn10/IS10 transposase that relies on the aggregation of the protein after overexpression in Escherichia coli. Aggregated transposase was solubilized before the final purification step, a gel-filtration column, using a combination of salt and detergent. This procedure is the first reported for the preparation of concentrated and active transposase from any IS element. The yield is 11 mg of purified protein at a concentration of 1 mg/ml from 2.5 g of cells. The procedure can be scaled up with ease. We also describe a treatment that activates transposase in either a crude or purified state. This involves dilution into a solution of salt plus organic solvent. In transposition reactions using supercoiled substrate plasmid, the activity was directly proportional to the amount of transposase added over a wide range of transposase/DNA ratios (0.2-2.0 molecules/DNA substrate molecule). In this range 8 transposase molecules were added per transposition event. Maximum conversion of substrate to product (40%) was with 18 transposase molecules/transposition event. At higher levels of transposase with a constant amount of substrate, activity was reduced but could be restored by addition of nonspecific DNA. Both the specific activity of transposase and the type of products generated can be altered by changing in vitro assay conditions. The effects of salts, solvents, and pH value on the reaction are described.
Design of remote control units for seniors (1994)

HumRRO International, Inc. conducted a project to improve the human factors aspects of remote control unit (RCU) design. Although the research was oriented toward RCUs for future telerobots that older adults may use, the RCUs examined were currently available models. An observational study found that a sample of 18 persons aged 65-88 years made errors in performing a simple arithmetic task with four different handheld calculators and that 13 participants made errors operating 11 VCR remotes. Better human-machine designs in RCUs appear to be needed to reduce errors that might cause accidents in the future use of mobile telerobots and their manipulators. In addition, manufacturers of RCUs, gerontologists, and members of SeniorNet, a network of older adults interested in computers, were queried regarding the design of RCUs. The responses of these individuals and the participants in the observational study, together with human factors engineering analyses, suggested numerous design improvements that may be systematically examined.
Nortriptyline-fluphenazine vs. carbamazepine in the symptomatic treatment of diabetic neuropathy. (1996)

We compared the efficacy and tolerance of the combination of nortriptyline-fluphenazine (NF) vs. carbamazepine (CMZ) in the symptomatic therapy of patients with severe, distal, symmetrical, predominantly sensitive diabetic polyneuropathy (DPN). We followed a double blind, crossover, randomized and double placebo design. Sixteen patients with severe DPN participated in the study. Patients received either NF (1 tablet three times a day (tid)), for 2 weeks and 2 tablets tid for the next 2 weeks or CMZ 1/2 tablet tid for 2 weeks and 1 tablet tid for the next 2 weeks. After this, patients received placebos of both drugs (wash-out period), until symptoms returned to baseline levels (100%), then they were crossed over to receive the other comparing drug schedule. A visual analogue scale was used to evaluate the percent changes in pain and paresthesia. HbA1, fasting serum glucose, and safety tests were performed at 2- and 4-week intervals, respectively. Both therapies produced significant improvement of both pain and paresthesia. No statistically significant differences were observed between both therapies for either pain or paresthesia. No significant biochemical changes were observed with any of the two therapies. Side effects were mild and more frequent in the NF period. In this study no superiority of either drug schedule was demonstrated; therefore, the decision to use any of them should be made according to the associated pathology and potential side effects of each drug.
[Rapid detection of 18-trisomy syndrome using primed in situ labeling technique]. (2004)

The results suggest that PRINS technique is simple, rapid and cost-effective. It is sensitive, specific, and thus can enhance the accuracy of standard cytogenetic analysis.
Automated pin grid array package routing on multilayer ceramic substrates (1993)

In the packaging router, routing is divided into two phases: topological routing and physical routing. Topological routing determines the topology of the paths layer by layer. Instead of using minimal spacing rules, for the given electrical constraints, the algorithm uses weighted spacing rules to optimize I/O performance. Physical routing builds the detailed structures of the connections. It permits variable RLC trade-offs. The overall time complexity is linear in the number of I/O pins. A practical packaging router was implemented. The experimental results show that this routing tool significantly improved the performance and the productivity of packaging design.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Numerical modeling of partial discharges in a solid dielectric-bounded cavity: A review (2019)

Partial discharge (PD) taking place in a solid dielectric-bounded cavity involves physical processes such as free electron supply, discharge development and surface charge decaying, which bring about memory effects and become the main reasons for stochastic behavior of PDs. This paper reviews numerical modeling of cavity PD in the past 30 years. In the first place, physical processes relevant to PD activity are summarized, and modeling methods for discharge development are classified. Then some differences of PD modeling at AC and DC voltages are distinguished. Subsequently, reproducing methods from simulations to experiments are introduced, as well as their comparison under different conditions and with the emphasis on voltage frequency and PD aging. At last, some problems about current simulation models are discussed, and our suggestions for future work are proposed.
Prevalence and reversibility of the hepatopulmonary syndrome after liver transplantation. The Cleveland Clinic experience. (1995)

To ascertain the prevalence and reversibility of the hepatopulmonary syndrome, we reviewed the cases of 98 patients undergoing liver transplantation at the Cleveland (Ohio) Clinic Foundation from June 1988 through July 1992 and identified 4 patients with clinically recognized hepatopulmonary syndrome (prevalence 4%). All 4 patients ultimately had complete reversal of their disorder. As reviewed herein, the prevalence of the hepatopulmonary syndrome in the current series is lower than in previous reports, possibly reflecting a dependence on its clinical recognition in this series rather than the use of routine screening tests. This report confirms previous experience that the hepatopulmonary syndrome may be reversible after transplantation.
Effect of tension on coercive force in amorphous (Fe1−xCox)77Si10B13 ribbons (1981)

Coercive force Hc was measured from observation of hysteresis loop as a function of tension σo and x in amorphous (Fe1−xCox)77Si10B13 ribbons. Tensions up to 4×109 dyne/cm2 and ac field, 380 Hz and 2.5 Oe max., were applied along the axis of straight ribbon. In the positive λs alloys (x?0.9), hysteresis loop easily became square type with increasing σo: After square type was attained, Hc increased almost linearly with further increase of σo. The rate of this increase, ΔHc/Δσo, was found to vary with x and to be nearly proportional to λs(x)/Ms(x). This result was qualitatively well explained from the viewpoint of wall coercive force with assumption of simple domain configuration.
Potential application of plant essential oils at sub-lethal concentrations under extrinsic conditions that enhance their antimicrobial effectiveness against pathogenic bacteria (2010)

The aim of the present study was to assess the effect of extrinsic factors on the antimicrobial effectiveness of essential oils (EOs) against medically important gram positive and gram negative bacteria. Clove, oregano, bay and cinnamon essential oils were tested against Salmonella typhimurium, Escherichia coli, Bacillus cereusand Listeria innocua. Agar diffusion test was used to estimate the strength of the essential oil. Clove was most effective against all groups of bacteria. The minimum inhibition concentrations (MIC) of the four essential oils ranged from 1.25 to 3.50% (v/v) as  determined by turbidimetric technique using Biocreen C, analyzer. In order to test the combined effect of pH, sodium chloride, temperature and EOs on the growth of bacteria, the concentrations of the EOs were set at 0.03125% (v/v) below MICs. A synergistic effect against the test bacteria was achieved at the concentration 1.2% (w/v) NaCl and either oregano or clove oil (P < 0.01), however clove was bactericidal on both classes of bacteria at 37°C, pH 5.5 and in combination with NaCl at 1.8% (w/v) pH (7.3), suggesting that EOs can be combined with NaCl at low concentrations overcome organoleptic effects in food and inhibit growth of pathogenic bacteria.

Bioenergetic models of the threatened darter<i>Percilia irwini</i> (2012)

Standard and active metabolisms determine the key aspects of the development and survival of fish species. We describe the first bioenergetic model for the standard metabolic rate (SMR) and active metabolic rate (AMR) of the Chilean native darter Percilia irwini. Adult individuals (5.5 ± 1.2 cm, 2.1 ± 0.9 g) were tested in a Blaska-type respirometer at 19.5 ± 0.5°C. Fish held a position by resting at the bottom at low velocities (5 and 15 cm s−1) and by swimming at higher velocities (25 and 35 cm s−1). SMR = 0.166 M 1.39 with an average of 220 mg O2 h−1 kg−1. Two bioenergetic models for AMR were adjusted. AMR = 0.16 M 1.16 U 0.23 at low velocities and AMR = 0.026 M 0.77 U 0.97 at higher velocities. Therefore, low velocities have little effect on the active metabolism of this species, but it is the main factor at higher velocities. Metabolic scope per unit weight was larger for smaller individuals, which is consistent with the faster growth of younger individuals.
Handling Policy Conflicts in Call Control (2005)

Abstract. Policies are becoming increasingly important in modern computer systems as a mechanism for end users and organisations to exhibit a level of control over software. Policies have long been established as an effective mechanism for enabling appropriate access control over resources, and for
Predicting the components of German nominal compounds (2002)

Word prediction systems (such as those embedded in most current augmentative and alternative communication systems) aim to predict what a user wants to type next on the basis of corpus-extracted ngram counts. Good performance of such a system depends crucially on the size and quality of the underlying lexicon. Compounding is a common cross-linguistic way to form complex words. In German as in some other languages, compounds are commonly written as single orthographic strings. Because compounding is a very productive process, this leads to a considerable amount of orthographic words that cannot, even in principle, be listed in a lexicon. We present a solution to this problem based on the idea that compounds should not be predicted as units, but as the concatenation of their components. In particular, we designed a word prediction system in which the prediction of German two-element nominal compounds (by far the most common compound type in German) is split into the prediction of the modifier (left element) and the prediction of the head (right element). Both components are predicted on the basis of uniand bigram statistics collected treating modifiers and heads as independent units, and on the basis of the type frequency of nouns in head and modifier context in the training corpus. We show that our system brings a dramatic improvement in keystroke saving rate over a word prediction scheme in which compounds are treated as units. In particular, our results indicate that the type frequency of nouns in head/modifier context in the training corpus is a very good predictor of which nouns will occur in head/modifier context in new text. 1
Output feedback sampled-data control of nonlinear systems using high-gain observers (2001)

This paper studies sampled-data control of nonlinear systems using high-gain observers. The observer is designed in continuous time, then discretized using three different discretization methods. Closed-loop analysis shows that the sampled-data controller recovers the performance of the continuous time controller as the sampling frequency and observer gain become sufficiently large. The theory is illustrated by experimental results.
Face Hallucination Via Weighted Adaptive Sparse Regularization (2014)

Sparse representation-based face hallucination approaches proposed so far use fixed ℓ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> norm penalty to capture the sparse nature of face images, and thus hardly adapt readily to the statistical variability of underlying images. Additionally, they ignore the influence of spatial distances between the test image and training basis images on optimal reconstruction coefficients. Consequently, they cannot offer a satisfactory performance in practical face hallucination applications. In this paper, we propose a weighted adaptive sparse regularization (WASR) method to promote accuracy, stability and robustness for face hallucination reconstruction, in which a distance-inducing weighted ℓ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">q</sub> norm penalty is imposed on the solution. With the adjustment to shrinkage parameter q , the weighted ℓ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">q</sub> penalty function enables elastic description ability in the sparse domain, leading to more conservative sparsity in an ascending order of q . In particular, WASR with an optimal q > 1 can reasonably represent the less sparse nature of noisy images and thus remarkably boosts noise robust performance in face hallucination. Various experimental results on standard face database as well as real-world images show that our proposed method outperforms state-of-the-art methods in terms of both objective metrics and visual quality.
증기급속응축법에 의한 Fe - Ni 계 합금 초미립자의 제조 (1995)

A new process, named ERC (Evaporation and Rapid Condensation) method, had been developed for the production of a large amount of isolated ultrafine particles(UFP). This method is based on a phenomenon of evaporation and condensation, but can be also said to be a kind of enhanced evaporation technique because of sucking the metal vapor generated from a molten metal. Therefore, in this paper, in order to investigate whether ERC method can be applied in preparation of alloy ultrafine particles, Fe-Ni alloys were tested. And the shape, the content and the morphology of obtained UFP were observed by TEM-EDX, SEM-EDX and X-ray diffraction analysis. Most of the obtained alloy particles were spherical, and the mean particle size was 15㎚. And the content of the obtained Fe-Ni alloy UFP almost agreed with that of equilibrium vapor of mother alloy, and the lattice parameter of the Fe-Ni alloy UFP was equal to that of mother alloy. Therefore, it was found that this method can be applied in preparation of alloy UFP.
MMP-9 Microsatellite Polymorphism and Susceptibility to Carotid Arteries Atherosclerosis (2006)

The number of repeats (> or =22 CA) in the microsatellite of MMP-9 promoter, but not MMP-9 plasma levels, is associated to carotid atherosclerosis and particularly to plaques with a thin fibrous cap.
The therapeutic effect of homologous and heterologous antitoxins in experimental diphtheria and tetanus. (1970)

Antitoxic sera against diphtheria and tetanus toxins were prepared in mice, guinea-pigs, rabbits and monkeys. The therapeutic effect of the antitoxins was compared in mice injected subcutaneously with tetanus toxin and in guinea-pigs injected intracutaneously with diphtheria toxin. The comparisons were made by varying the time interval between the injection of constant doses of toxin and antitoxin. Homologous antitoxin was not found to have any superiority over heterologous antitoxin in controlling the effects of the toxin injections. It is suggested that when used therapeutically the dose of homologous antitoxin should be the same as that of heterologous antitoxin.
Study of malarial chemoprophylaxis and pregnancy gingivitis in Nigerian women. (1992)

Resolution of pregnancy gingivitis during pregnancy despite the usual therapy of scaling has not proved to be satisfactory. A clinical study of pregnancy gingivitis in 55 pregnant women (23 primigravid, 32 multigravid) showed pyrimethamine prophylaxis had a significant positive effect in the resolution of gingivitis during pregnancy. At the end of the gestation period, pregnant women who received pyrimethamine as malarial chemoprophylaxis showed significant improvements, as compared with placebo, in relation to gingival bleeding and enlargement, whether primigravid or multigravid. These clinical observations suggest that pyrimethamine may exhibit properties that may be inflammatory, act as immune enhancer and antihyperplastic agent by probably possessing an antagonistic effect upon nucleic acid synthesis.
Focus and context for volume visualization (2004)

Scientific investigation and simulation have been producing increasingly large datasets. Usually that kind of data is visualized employing some scientific visualization technique. Another related field, information visualization, deals with nonscientific large scale data, using different approaches to achieve an effective understanding. Our aim is to bring these two fields together, proposing a taxonomy for volume visualization, employing information visualization techniques, particularly the focus and context idea. A prototype is being developed, which aims to implement and evaluate a number of solutions for this problem, identifying through demonstration which applications would benefit most from focus+context approaches. We describe work in progress.
Mobile computing in military ambulatory care (2002)

Although satellite and cellular communication advances have enabled users of mobile computers the ability to access information regardless of location, it introduces new problems for transaction management in distributed database systems. Traditional transaction mechanisms and criteria have to be adjusted to accommodate the limitations of a mobile computing environment. Data replication is an example of a technique that is used in traditional database systems to increase the availability and the fault-tolerance of the data, but at the same time adds the overhead of maintaining replica consistency across multiple sites of the network. Data replication is a useful tool in mobile computing due to the fact that a mobile host may be disconnected from the network for long periods of time. The data replication allows the mobile host to use a local data copy while it is disconnected from the network. Mobile hosts that have the capability to store copies of data items increase the difficulty of maintaining replica consistency, because of the mobile host's volatile storage. Also, the mobile host must be assured that the local copies that it is using are valid, and any changes made locally to a copy are reflected in the rest of the system. We introduce a mobile replica management algorithm. A mobile transaction manager (MTM) coordinates the transactions initiated by mobile hosts, which query and update replicated databases stated at both mobile and static hosts in a battlefield environment. This battlefield environment is based upon the U.S. telemedicine (Prime Time III) support in Bosnia. The MTM is responsible for the synchronization of the replicated data items in the network.
Influence of external cavity length on the coherence collapse regime in laser diodes subject to optical feedback (2001)

A theoretical investigation of the stability of laser diodes subject to optical feedback from short external cavities has been undertaken. Unstable (chaotic) behaviour was found to be restricted to islands in the feedback strength and cavity length phase plane in short cavities. A study has been made of the transition from isolated islands of unstable behaviour to that of one continuous unstable region. This transition occurs as the external cavity length is gradually increased and accounts for the phase insensitive behaviour seen in the long cavity limit.

Intracellular cyclic GMP receptor proteins (1993)

Cyclic GMP is recognized as an important intracellular mediator of extracellular signals such as nitric oxide and natriuretic peptides. Cyclic GMP interacts with three types of intracellular receptor proteins: cGMP-dependent protein kinases, cGMP-regulated ion channels, and cGMP-regulated cyclic nucleotide phosphodiesterases. This means that cGMP can alter cell function through protein phosphorylation or through mechanisms not directly related to protein phosphorylation. Cyclic GMP appears to regulate a number of intracellular processes, such as vascular smooth muscle relaxation and neutrophil activation, through these receptor proteins in the cell. It is also becoming clear that the localization of these cGMP receptor proteins in the cell is an important factor in the regulation of cell function by cGMP.
