On the design of bandwidth efficient signalling for indoor wireless optical channels: Research Articles (2005)

It is well known that indoor wireless optical channels are limited not only in transmitted optical power, but also in signalling bandwidth. This bandwidth constraint arises due to multipath dispersion in indoor settings as well as due to response time limitations of optoelectronic components.This paper presents an overview of theoretical and practical issues in the design of signalling for bandwidth constrained intensity modulated, direct detection wireless optical channels. A brief overview of the salient qualities of the wireless optical channel are presented to highlight the amplitude constraints which arise. A survey of modulation design is then presented which includes the review of a general technique to represent optical intensity modulation in a signal space and to construct optical intensity lattice codes. Results on the channel capacity of indoor wireless optical channels are surveyed and particular emphasis is placed on recently derived asymptotically exact bounds. The use of multiple emitters and receivers in wireless optical channels is also presented and particular emphasis is placed on techniques which exploit spatial dimensions to improve spectral performance. The paper concludes with some remarks regarding the status of the research area and suggestions for future work. Copyright © 2005 John Wiley & Sons, Ltd.

Mathematical modeling of the head and neck response to -Gx impact accelration (minimum articulation requirements). (1978)

Data on the dynamic response of the living human head and neck to -Gx impact acceleration was analyzed. The Calspan 3-D Computer Simulator of a Motor Vehicle Crash Victim was used to provide estimates of the head and neck response to be expected for the very specific deceleration profiles simulated. Two segments connected via a pivot were used to represent the head-neck system. The monitored T1 deceleration profile was used to drive this system and the simulation head-neck response was checked for accuracy in replicating motional characteristics and trends in the response mechanism. Two head pivot locations were considered. The first was the occipital condylar point and the second was a theorized hingepoint in the head which minimized the distance from this point to the T1 anatomical coordinate system over the range of body orientations observed in the photographic data. For the two geometrical representations, a successive approximation technique was employed to analyze the resulting data. This approach initially removed all constraints to head and neck motion, and the resulting simulation results were compared to the human data. Restrictions to head and neck motion were then successively added until an adequate replication of the human data was obtained. This approach made it possible to correlate specific events, such as loading of the head-to-neck dorsiflexion limiting angle, to head deceleration profile characteristics. Results were compared to calculations obtained for eight additional subjects and proved to be in good agreement.
Senile aortic amyloid. A third distinctive type of age-related cardiovascular amyloid. (1982)

Aortic tissues from 22 elderly patients were analyzed by Congo red staining for amyloid deposits. All samples contained amyloid, which was resistant to the potassium permanganate reaction. Tryptophan was present in all amyloid deposits. The amyloid failed to react with antiserums to amyloid fibril protein ASc1 or human prealbumin, proteins previous demonstrated in generalized senile cardiac amyloid. It also differed from age-related isolated atrial amyloid, which has been shown to lack tryptophan. Deposits did not react with antiserums specific for amyloid fibril proteins of the A lambda IV, A lambda VI, AA, or AEt types. These results indicate that senile aortic amyloid is distinct from amyloid present in primary and secondary amyloidosis and appears to represent a third form of cardiovascular amyloid associated with the aging process.
Dewatering of Coalbed Methane Wells with Hydraulic Gas Pump (1995)

Abstract The coalbed methane industry has become an important source of natural gas production. Proper dewatering of coalbed methane (CBM) wells is the key to efficient gas production from these reservoirs. This paper presents the Hydraulic Gas Pump as a new alternative dewatering system for CBM wells. The Hydraulic Gas Pump (HGP) concept offers several operational advantages for CBM wells. Gas interference does not affect its operation. It resists solids damage by eliminating the lift mechanism and reducing the number of moving parts. The HGP has a flexible production rate and is suitable for all production phases of CBM wells. It can also be designed as a wireline retrievable system. We conclude that the Hydraulic Gas Pump is a suitable dewatering system for coalbed methane wells.
A study of application techniques for mica mat tapes (1965)

The results of this study indicate: 1. Increased voltage life is attainable with wide tapes as contrasted to narrow tapes. 2. Increased voltage life is attainable with thick tapes having an increased mica content. 3. Increased voltage life is related to the flexibility of the tape or wrapper being applied and its ability to conform to the coil. 4. The use of wrappers will provide a significant increase in voltage life as compared to the equivalent build with tapes. 5. Proper indexing of multiple layers of tape will increase voltage life of the insulation wall by as much as 3 fold.

Diode and transistor equivalent circuits for transient operation (1969)

Solid-state devices have complex energy storage effects that complicate their transient operation. A frequently used method of analysis is that of charge control. This method relies upon quasi-static equilibrium and may have significant errors for high-speed operation. The method proposed uses a series approximation to a convolution integral solution. The first term of the series is equivalent to charge-control operation and higher order terms provide improved accuracy in terms of lumped elements of an equivalent circuit, but the real merit of the series form is its ready adaptability to computer- programmed node-branch circuits analysis.
Antimicrobial activity of plant based Essential Oils and Synergistic effect against selected Human Pathogenic Bacteria (2020)

The occurrence of multidrug resistant by pathogens is a universal issue for providing tolerable treatment for various infectious diseases. The predictable anti-microbial proxies are relatively active against plentiful strains, still need of more drugs against multidrug resistant pathogens. Herbal drugs have potential against antimicrobial activity from ancient days and their treatment of pathogenic diseases is increasing for developing plant based natural products. Essential oils have combat against antibiotic resistant bacteria. Thus our study was focused on plant based essential oil against human pathogenic bacteria. The necessary oil extracted from Curcuma longa and C. martini revealed protuberant anti-microbial accomplishments against B. subtilis, Escherichia coli, P. aeruginosa and S. aureus. Low concentration of C. longa oil at 10 µl inhibited the growth of all strains Bacillus subtilis followed by E. coli and S. aureus. Maximum bustle was noted in P. aerogenosa at 40 µl in both C. longa and C. martini oils. Human pathogenic strain treated with C. martini oil showed maximum inhibition in P. aerogenosa followed by B. subtilis, E. coli and S. aureus. Synergistic activity of oils against the strains showed maximum inhibition at 40 µl in P. aerogenosa.

Mercury capture in bench-scale absorbers (1994)

This paper gives,a brief overview of research being conducted at Argonne National Laboratory on the capture of mercury by both dry sorbents and wet scrubbers. The emphasis in the research is on development of a better understanding of the key factors that control the capture of mercury. Future work is expected to utilize that information for the development of new or modified process concepts featuring enhanced mercury capture capabilities. The results and conclusions to date from the Argonne -research on dry sorbents can be summarized as follows: lime hydrates, either regular or high-surface-area, are `not effective in removing mercury; mercury removals are enhanced by the addition of activated carbon; mercury removals with activated carbon decrease with increasing temperature, larger particle size, and decreasing mercury concentration in the gas; and chemical pretreatment (e.g., with sulfur or (CaCl{sub 2}) can greatly increase the removal capacity of activated carbon. Preliminary results from the wet scrubbing research include: no removal of elemental mercury is obtained under normal scrubber operating conditions; mercury removal is improved by the addition of packing or production of smaller gas bubbles to increase the gas-liquid contact area; polysulfide solutions do not appear promising for enhancing mercury removal in typical FGC systems; stainless steel packing appears to have beneficial properties for mercury removal and should be investigated further; and other chemical additives may offer greatly enhanced removals.

Experimental Investigation of the Cutting Force Measurements in Machinability Evaluations of Metals (2014)

Abstract Cutting tools need to be changed constantly while the machinability of materials is evaluated by cutting force measurements. However, little attention has been paid to the variation of the cutting force caused by such a tool change. In this study, a homogeneous material was used as the cutting object and an ordinary, mechanically clamped, external cutting tool was used. For the same cutting parameters, when the tool wear can be ignored, the effects of the insert resetting and the whole mechanically clamped cutting tool remounting on the main cutting force were examined. The change in the cutting force caused by the insert resetting and replacing is less than 2 %, while that caused by remounting of the whole mechanically clamped cutting tool is as great as 11 %. If the cutting force is used to evaluate the machinability of materials, a mechanically clamped tool should be used, and the insert can be replaced, but the tool holder should be mounted once only for all subsequent tests. This conclusion is very important for accurate measurement of the cutting force and accurate evaluation of the metal machinability.
Les zones Agricoles protégées: figer de l'espace agricole pour un projet agricole ou organiser le territoire pour un projet urbain ? (2007)

L'objectif de cet article et de saisir le jeu des différents discours et des représentations lors de l'élaboration de zones agricoles protégées. L'étude de deux cas empiriques en zone périurbaine met à jour les discours et leur traduction en termes de protection d'espaces agricoles : les communes qui utilisent l'outil ZAP ont un projet de territoire et le portent. On assiste à une remise en cause de la démarche descendante. L'appropriation de l'espace rural par les politiques locales marque la fin du monopole des agriculteurs sur le développement agricole. La ZAP matérialise un accord superposant la préservation du paysage et le fonctionnement d'une agriculture productive insérée dans la filière économiques.
Membranes for Continuous Nonenergized Air Freshener Perfume Delivery (2017)

Membrane-based liquid air fresheners are attracting significant market interest because of their small size and ability to allow continuous delivery of perfume compounds without the need of external energy sources. However, the air freshener membranes that enable the nonenergized delivery are rarely reported in the literature except in patents. For the first time, we investigated a commercial air freshener membrane systematically to provide thorough characterizations of the membrane materials, morphology, and pore information. The interaction between a model perfume containing four compounds and the membrane was also studied through liquid wetting and contact angle measurements. Long-term tests to track the air freshener revealed that the perfume release rate was dependent on the perfume reservoir composition in a controlled external environment. Lastly, perfume transport through the membrane was investigated for the correlation of membrane properties and liquid flux through the membrane. This pioneering study may provide essential information for future improvement over the existing air freshener membranes to enable continuous perfume delivery without an energy provision.
E-BioSci: an Europe-based platform for E-publishing and information integration in the life sciences (2001)

Just as the emerging field of genomics is changing the way in which molecular biologists plan, execute and interpret their research, so is the transi- tion from traditional to electronic publishing technolo- gies changing the ways in which the results of this re- search is disseminated to and used by other scientists. Paper is turning out to be an inadequate medium for the flood of new data that often demands both further ma- nipulation and new methods of visualization as an aid to interpretation. The typical research scientist therefore wishes to have free, or at least unhindered access to as wide a range of electronic information sources as possi-
On the Development of Pseudoephenamine and Its Applications in Asymmetric Synthesis (2014)

Pseudoephedrine is well established as a chiral auxiliary in the alkylation of amide enolates to form tertiary and quaternary carbon stereocenters. However, due to its facile transformation into the illegal narcotic methamphetamine, pseudoephedrine is either illegal or highly regulated in many countries, which limits its use in academic and industrial settings. To address this issue, pseudoephenamine has been developed as a replacement for pseudoephedrine in organic synthesis. This new auxiliary suffers no regulatory issues and exhibits several practical advantages over pseudoephedrine, including the high diastereoselectivities observed in alkylation reactions forming quaternary carbon stereocenters, the propensity for pseudoephenamine amides to be free-flowing crystalline solids, and the sharp, well-defined peaks that typically compose the 1H NMR spectra of these amides.
Quality of life in patients with plaque psoriasis treated with biologic therapies (2013)

Numerous publisched studies have shown impaired health - related quality of life (HRQoL) in patients with psotiasis. Objective. To evaluate the impact of biologic treatments on HRQoL in clinical practice. Methods. A prospective observational study was condeuced at 12 Psocare Centers in Italy and included patients with chronic plaque psoriasis switching to biolocic therapy after a suspension of at list 1 year. HRQoL was assessed at enrolment and after 6 months of treatment with biologics. Results. A totalo of 185 patients were enrolled, of which 178 were included in the analysis. At enro lment, moderate or serever anxiety and drepession were reported by 46.6% and 34,8% of patients, respectively. Psychogical problems were unrelated to objective assessment of disaese severity. Significant proportions of patients reported sexual problems, embarrassment about their condition and appearance, cloting choices being affected, and concern over possible future effects of the disease. After 6 months of treatment with biolologics the propotions of patients reporting these disease - related problems reduced. Conclusion. This study demostred that biologic treatment improve HRQoL in patients with plaque psoriasis. It also highlights the importance of HRQoL as a key measure of the efficacy of treatments for the condition.

Prognostic significance of expression of p53 oncoprotein in primary (stage I-IIIa) non-small cell lung cancer. (2003)

Mutation of the p53 gene is one of the most common genetic abnormalities found in all types of human cancer. Accumulating evidence strongly indicates that p53 alterations play a role in tumorgenesis in non-small cell lung cancer (NSCLC). However, the role of p53 as a prognostic marker in NSCLC remains unclear. The data derived from the literature on prognostic impact of p53 in NSCLC has been a matter of controversy. Among the reasons for the discrepancy, are lack of correlation with key clinical parameters, patients with different stages, different antibodies used, and insufficient sample size. The intent of this study was to evaluate the prognostic value of p53 protein in a larger cohort of stage I-IIIa patients. Clinicopathological data was obtained on 179 patients with NSCLC. These data were correlated with the p53 status on the respective surgically resected tumors, using monoclonal antibody DO7. There is a significant relationship between strong p53 expression and patient survival. In a multivariate analysis, strong expression (> 50%) of the p53 oncoprotein is an independently favorable prognostic factor. Patients with strong p53 expression had a prolonged survival (p = 0.009, RR; 0.56, 95% CI: 0.35-0.86). The median time of survival for patients with strong and negative/weak p53 expression was more than 61 and 44 months, respectively. The present study suggests that p53 protein expression in tumor tissue may serve as a prognostic biomarker for NSCLC. This information may also potentially serve as a tool for clinical decision-making when selecting patients for adjuvant treatments of NSCLC.
The reconstitution of unfolded myoglobin with hemin dicyanide is not accelerated by fly‐casting (2004)

This study explores how the kinetics of a coupled folding/binding reaction depend on the initial conformation of the protein. Stopped-flow spectroscopy is used to monitor the reaction of apo-myoglobin (aMb) with hemin dicyanide at pH 7.2. Different initial aMb conformations are tested. In the case of acid-denatured aMb, the observed kinetics are consistent with a "fly-casting" scenario [Shoemaker et al., Proc. Natl. Acad. Sci. USA 97 (2000) 8868-8873]. However, the formation of a compact complex proceeds more rapidly in the case of prefolded aMb. This finding is opposite to what would be expected based on predictions of the fly-casting model.

A portable electroantennogram sensor for routine measurements of pheromone concentrations in greenhouses (1998)

Abstract Mating disruption using pheromone dispensers is an emerging insect control method in greenhouses in the Netherlands. For routine measurements of the pheromone level in greenhouses a portable and compact device based on electroantennography (EAG) was developed. The instrument was tested in different greenhouses under varying conditions using antennae of males of the noctuid moth Chrysodeixis chalcites . Relative differences in pheromone concentration between greenhouses loaded with pheromone dispensers and control greenhouses could be measured in a reliable way. Changes in pheromone concentration were clearly demonstrated by measurements during the growing season. The advantages of the instrument presented over previously described devices are its true portableness, ease of use and uncomplicated measuring principle. The device can be operated routinely by non‐experts, and many measurements can be made in a short period of time. Preliminary outdoor measurements using antennae of male Cydia pomonella as sensor showed the potential of the instrument for use in the open field. The portable EAG sensor described here may provide a practical means for monitoring pheromone concentration and dispersal from dispensers applied for mating disruption.
Treatment of acute myelogenous leukemia in adults with N4-behenoyl-1-β-D-arabinofuranosylcytosine (1985)

Forty-five previously-untreated adult patients with acute myelogenous leukemia (AML) were treated with N4-behenoyl-1-beta-D-arabinofuranosyl-cytosine (BHAC) in a multi-institutional cooperative study. Among 41 evaluable patients, 15 (36.6%) achieved complete remission (CR) and 10 (24.4%) achieved partial remission by daily administration of 3 to 8 mg/kg of BHAC. Higher daily doses (5 mg/kg or more) produced higher CR rates, and all of the CR were observed among the patients receiving a total BHAC dosage of 50 mg/kg or more in a period of 10 days or more. The side effects were mild and acceptable: nausea-anorexia was observed in 27% of the patients and vomiting in 17%. The results of this study thus indicate BHAC to be effective for remission induction of AML, and to deserve further clinical trials in combination with other anti-leukemic drugs.
