A new one-pot synthetic method for preparing core/shell YF3@SiO2 nanoparticles with different morphologies, from spherical to elongated structures ("pearl necklace"), is described; absorbance and photoluminescence spectroscopy reveals intrinsic but no extrinsic defects in the YF3.
A Case Study of an RFID-based System for Pilgrims Identification and Tracking (2010)

Hajj season poses many challenges for the authorities. The main challenges have been reviewed in this work based on official reports, interviews with key officials and the authorsâ€™ personal experience. Using advanced technologies is very promising in tackling these challenges. In this project, we have demonstrated the use of RFID technology to ease some of these challenges A pilot system was carried out to experiment the system during Hajj season. The prototype RFID-based Pilgrim Identification System was tested with a group of 1000 pilgrims from Ivory Coast. This experiment proved to be very successful in demonstrating the benefits of the system. In particular, it demonstrated the effectiveness of RFID system in removing bottlenecks of the traditional authentication system. This is due to the fact that checking a wristband tag by the reader takes a small fraction of the time it takes to authenticate the paper permit.
Anti-inflammatory Mechanism of the Volatile Oil of Magnolia biondii Pamp. (2005)

Wistar Rats were adrenalectomized.7 days later,1% carrageenan was injected into the rats′ thoracic cavity,and 10% egg-white subcutaneously on their right foot.Therefore,pleurisy and inflammation of foot occurred to the rats.The Voatile Oil of Magnolia biondii Pamp.(VOMP) was given to the treatment rats before the injection of inflammagen.The results showed that VOMP can relieve the inflammation,and inhibit the production of inflammatory mediators,such as TNF,histamine,PGE_2 and the activity of PLA_2.These indicated that the anti-inflammatory effect of VOMP wasn′t relevant to the animals′ hypothalamus-adenohypophysis-adrenal axis.
Modulation Scheme for the Bidirectional Operation of the Phase-Shift Full-Bridge Power Converter (2019)

This paper proposes a novel modulation technique for the bidirectional operation of the phase-shift full-bridge (PSFB) dc/dc power converter. The forward or buck operation of this topology is well known and widely used in medium-to-high-power dc-to-dc converters. In contrast, backward or boost operation is less typical since it exhibits large drain voltage overshoot in devices located at the secondary or current-fed side—a known problem in isolated boost converters. For that reason, other topologies of symmetric configuration are preferred in bidirectional applications. In this work, we propose a modulation technique overcoming the drain voltage overshoot of the isolated boost converter, without additional components other than the ones in a standard PSFB and still achieving full or nearly full ZVS in the primary or voltage-fed side devices along all the load range. The proposed modulation has been tested in a bidirectional 3.3 kW PSFB achieving a 98% of peak efficiency in buck mode (380 V input, 54.5 V output), and a 97.5% in boost mode (51 V input, 400 V output). This demonstrates that the PSFB converter may become a relatively simple and efficient topology for bidirectional dc-to-dc converter applications.
Silver thiogallate, singly resonant optical parametric oscillator pumped by a continuous-wave mode-locked Nd:YAG laser (1994)

We describe a silver thiogallate (AgGaS(2)) singly resonant optical parametric oscillator (OPO), synchronously pumped by a continuous-wave actively mode-locked Nd:YAG laser. The OPO is operated with a signal wavelength near 1.319 microm and an idler wavelength near 5.505 microm. At optimum output coupling, 100 mW of useful signal power and 6 mW of idler power are generated from 625 mW of pump power. The pump is mechanically chopped at a 32:1 duty cycle to prevent thermal lensing of the AgGaS(2) crystals. Pump depletion is as high as 63%. The signal has pulse widths ranging from 45 to 80 ps and spectral widths ranging from below 0.1 to 0.3 nm. The OPO signal can oscillate over a 2-mm range of round-trip cavity-length mismatch.
[Attenuation of the action of morphine in rats immunized with a conjugated morphine-protein antigen]. (1980)

The effect of immunization of rats with the conjugated antigen morphine-bovine serum albumin synthetized by the authors on the analgetic activity of morphine hydrochloride has been investigated. Morphine binding antibodies were shown to appear in the blood of rats during immunization. The spleen demonstrated mononuclear cells also capable of morphine binding. It has been established that immunization of rats with the above synthetic antigen makes them tolerate the pharmacological effects of the narcotic. Morphine at a dose of 5 mg/kg is not capable of inducing an inherent increase in the threshold of pain sensitivity in immunized rats. Immunization also slightly diminishes the morphine effect at a dose of 20 mg/kg on the EEC. Prolonged daily administration of morphine does not remove morphine tolerance due to immunization.
Si-CMOS-compatible lift-off fabrication of low-loss planar chalcogenide waveguides (2007)

We demonstrate, for the first time to the best of our knowledge, low-loss, Si-CMOS-compatible fabrication of single-mode chalcogenide strip waveguides. As a novel route of chalcogenide glass film patterning, lift-off allows several benefits: leverage with Si-CMOS process compatibility; ability to fabricate single-mode waveguides with core sizes down to submicron range; and reduced sidewall roughness. High-index-contrast Ge(23)Sb(7)S(70) strip waveguides have been fabricated using lift-off with excellent uniformity of loss propagation and the lowest loss figure of reported to date. We also show that small core Ge(23)Sb(7)S(70) rib waveguides can be fabricated via lift-off as well, with loss figures lower than 0.5 dB/cm. Additionally, we find through waveguide modal analysis that although overall transmission loss is low, the predominant source of this loss comes from scattering at the sidewalls.
A Hazard of Home Oxygen Therapy (2001)

Although it is generally safe, there are morbidities associated with home oxygen use. Experience in our burn unit led to an analysis of burn complications from this therapy. A retrospective review of records during a 12-year period identified 23 patients with burns associated with home oxygen use. Average age of the patients was 70 years, with chronic obstructive pulmonary disease the most prevalent indication for use. Concomitant cigarette smoking was the most common inciting mechanism of the burns (70%). Average burn size was 3.9% of total body surface area. Eleven patients presented in the first 10 years of the study period, whereas 12 presented in the last 2 years. We have seen a rise in injuries with the use of home oxygen. The absolute number of injuries sustained is unknown, because many are likely unreported. To decrease the morbidity and costs associated with these injuries, the need for continuing safety education is apparent.
Recent advances in Redox flow cell storage systems (1979)

Several features which were conceived and incorporated into complete redox systems that greatly enhanced its ability to be kept in proper charge balance, to be capable of internal voltage regulation, and in general be treated as a true multicell electrochemical system rather than an assembly of single cells that were wired together, were discussed. The technology status as it relates to the two application areas of solar photovoltaic/wind and distributed energy storage for electric utility applications was addressed. The cost and life advantages of redox systems were also covered.
Migrating from COBOL to Java (2010)

This paper is an industrial report on a project for migrating an airport management system from a Bull mainframe using COBOL as a programming language and IDS as a database system to a distributed UNIX platform using Java and Oracle. The focus here is on the automated language transformation, performed in three phases - reengineering, conversion and refinement. The tools used are COBRedo for reengineering the COBOL code, COB2Java for converting COBOL to Java and JavRedoc for documenting the converted Java code. The paper describes the migration process and the tools used in it and the reviews the current state of the project.
Synthesis of Amine−Borane Intramolecular Complexes through Palladium-Catalyzed Rearrangement of Ammonioalkynyltriarylborates (2008)

The palladium-catalyzed rearrangement reaction of alkynyltriarylborates having a tertiary ammonium moiety stereoselectively afforded amine-borane intramolecular complexes, some of which exhibited significantly strong fluorescence.
A Study of Electrical, Metallurgical, and Mechanical Behaviors of Rapid Thermal Processed Ti Films in  NH 3 (1994)

The electrical, metallurgical, and mechanical behavior of the Ti films heat‐treated in a rapid thermal processor in and ambient in the temperature range of 550 to 750°C were studied. In addition, formation of the film by rapid thermal nitridation (RTN) in ambient and its barrier integrity were also studied as a function of the nitridation temperature and duration. n+ and p+‐type silicon and thermal oxide were used as substrates. Electron spectroscopy for chemical analysis, Rutherford backscattering spectroscopy, and sputtered neutral mass spectrometry were used to study the extent of the interactions between N, Ti, and Si as well as identification of the phase and its thickness. The thermal stability of the film as a diffusion barrier was investigated in the temperature range of 400 to 475°C. The diffusion barrier integrity of the film and its thermal stability were investigated via substrate junction leakage current and contact resistance measurements done on test structures fabricated using a complete 1.0 and 0.85 μm complimentary metal oxide semiconductor erasible programmable read‐only memory mask sets. Presented data shows that the decrease in the sheet resistance and the increase in the stress of the heat‐treated Ti films as the temperature increases are due to the presence of silicon in the Ti films. Similar results were obtained when heat‐treatment was carried out in ambient. The analytical analyses indicate that the thickest film which can be formed by the RTN process in ambient, in the temperature range of 590 to 750°C, is only 200 to 240 Å and is formed at about 600 to 610°C. The substrate junction leakage current data taken from the test structures indicate that the film formed by one‐step nitridation in ambient is not electrically and thermally reliable as a diffusion barrier for fabrication of the integrated circuit devices with shallow junctions (≤0.2 μm) regardless of the nitridation temperature and duration, and as‐deposited thickness of the Ti film. This short‐coming is attributed to an inadequate thickness of the film and the formation of (Ti‐Si‐Al) ternary solution. Finally, to overcome this problem, a multistep nitridation process was developed that produced the thickest film at the contacts and on the oxide layer (borophosphosilicate glass/borophosphosilicate tetraethyl orthosilicate), as well as a layer under the film at the contacts. The diffusion integrity of this bilayer was also evaluated via substrate junction leakage current and contact resistance measurements. The results indicate the suitability of this film as a diffusion barrier for submicron integrated circuit devices having shallow junctions. Furthermore, these results indicate that the presence of the layer under the layer at the contacts is essential if the film formed by RTN process in ambient is to be used as a diffusion barrier.
Scalable Distributed Computing Hierarchy: Cloud, Fog and Dew Computing (2015)

The paper considers the conceptual approach for organization of the vertical hierarchical links between the scalable distributed computing paradigms: Cloud Computing, Fog Computing and Dew Computing. In this paper, the Dew Computing is described and recognized as a new structural layer in the existing distributed computing hierarchy. In the existing computing hierarchy, the Dew computing is positioned as the ground level for the Cloud and Fog computing paradigms. Vertical, complementary, hierarchical division from Cloud to Dew Computing satisfies the needs of high- and low-end computing demands in everyday life and work. These new computing paradigms lower the cost and improve the performance, particularly for concepts and applications such as the Internet of Things (IoT) and the Internet of Everything (IoE). In addition, the Dew computing paradigm will require new programming models that will efficiently reduce the complexity and improve the productivity and usability of scalable distributed computing, following the principles of High-Productivity computing.
Study of the Partial Crystallization Properties of Phase-Change Optical Recording Disks (1999)

The partial crystallization properties of Ge 1 Sb 2 Te 4 phase-change optical disks are studied using two methods. The first one involves annealing of the samples in a vacuum oven while controlling annealing time and temperature, while the second one involves the use of a static tester. A difference in reflectivity was observed, indicating that different crystallization fractions give rise to different reflection levels. The optical constants of amorphous, partial and full crystaline states were measured by spectroscopic ellipsometry. The optical constant of the partial crystalline state was calculated under the assumption that the partial crystalline state is a combination of full crystalline and amorphous states. The crystallization fraction was determined by simulating the refractive index of the partial crystalline state. The stability of the partially crystalized disk was measured for more than 200 days demonstrating that the partially crystallied disk is very stable. A possible recording strategy using the multilevel reflection to realize multi-level reflection modulation recording in write-once media is discussed.
Interaction of Pasteurella haemolytica with bovine neutrophils: identification and partial characterization of a cytotoxin. (1981)

Timed cultures of Pasteurella haemolytica 12296 strain in RPMI 1640 medium (with L-glutamine, pH 7.4) were used to determine the correlation between cytotoxin production and the age of the culture. Cytotoxic activity was measured by a 51Cr-release assay and trypan blue exclusion test with bovine neutrophils as target cells. Results demonstrated that optimal cytotoxin production occurred during the logarithmic phase (peaked at 6 hours) and decreased during the stationary phase of bacterial growth. The cytotoxin was concentrated by sequential ultrafiltration on Diaflo XM 50, XM 100, and XM 300 membranes. The cytotoxin was retained on an XM 300 membrane. These studies indicated that the molecular weight of cytotoxic substance was 300,000 or more. The cytotoxin was heat labile, oxygen stable, and susceptible to extremes of pH and killed bovine neutrophils and mononuclear leukocytes. It was not hemolytic to bovine or ovine RBC. The cytotoxic activity was inactivated by trypsin and did not contain any detectable endotoxin. Bovine fetal serum and serum collected before immunization from neonatal calves did not neutralize the cytotoxic effects of toxin on neutrophils. However, adult bovine serum from 6 cows and an antiserum (against the cytotoxin) neutralized the cytotoxin, as revealed by both the 51Cr-release assay and the trypan blue exclusion test. This was confirmed by transmission electron microscopy. These results indicated that the cytotoxin may be antigenic in cattle. The significance and implications of these findings to bovine pasteurellosis are discussed.
SOFC modelling and parameter identification by means of impedance spectroscopy (2010)

A high resolution electrochemical impedance spectroscopy study on anode supported single cells (ASC) is presented. The cells were characterised over a broad range of operating conditions, including different temperatures, current densities and various cathode and anode gas compositions. The analysis of the distribution of relaxation times combined with the numeric accuracy of a CNLS fit enabled the identification of five different processes contributing to the total polarisation loss of an ASC.
Red blood cell antibody-induced anemia causes differential degrees of tissue hypoxia in kidney and brain (2018)

Moderate anemia is associated with increased mortality and morbidity, including acute kidney injury (AKI), in surgical patients. A red blood cell (RBC)-specific antibody model was utilized to determine whether moderate subacute anemia could result in tissue hypoxia as a potential mechanism of injury. Cardiovascular and hypoxic cellular responses were measured in transgenic mice capable of expressing hypoxia-inducible factor-1α (HIF-1α)/luciferase activity in vivo. Antibody-mediated anemia was associated with mild intravascular hemolysis (6 h) and splenic RBC sequestration ( day 4), resulting in a nadir hemoglobin concentration of 89 ± 13 g/l on day 4. At this time point, renal tissue oxygen tension (P<sub>t</sub>O<sub>2</sub>) was decreased in anemic mice relative to controls (13.1 ± 4.3 vs. 20.8 ± 3.7 mmHg, P < 0.001). Renal tissue hypoxia was associated with an increase in HIF/luciferase expression in vivo ( P = 0.04) and a 20-fold relative increase in renal erythropoietin mRNA transcription ( P < 0.001) but no increase in renal blood flow ( P = 0.67). By contrast, brain P<sub>t</sub>O<sub>2</sub> was maintained in anemic mice relative to controls (22.7 ± 5.2 vs. 23.4 ± 9.8 mmHg, P = 0.59) in part because of an increase in internal carotid artery blood flow (80%, P < 0.001) and preserved cerebrovascular reactivity. Despite these adaptive changes, an increase in brain HIF-dependent mRNA levels was observed (erythropoietin: P < 0.001; heme oxygenase-1: P = 0.01), providing evidence for subtle cerebral tissue hypoxia in anemic mice. These data demonstrate that moderate subacute anemia causes significant renal tissue hypoxia, whereas adaptive cerebrovascular responses limit the degree of cerebral tissue hypoxia. Further studies are required to assess whether hypoxia is a mechanism for acute kidney injury associated with anemia.
Histamine as a Therapeutic Alternative in Migraine Prophylaxis: A Randomized, Placebo‐Controlled, Double‐Blind Study (1999)

This study was undertaken to test the efficacy of the subcutaneous administration (twice a week) of consecutively increasing doses of histamine (0.1 to 1 ng) in the prophylaxis of migraine, compared to placebo, under a controlled, double-blind, clinical trial for 12 weeks. Sixty patients were selected, under criteria established by the International Headache Society (both sexes, 18 to 65 years of age, a migraine history of more than 1 year, one to six headache attacks per month), having no additional neurological or cardiovascular pathologies, and after a complete clinical and laboratory examination including computer-assisted tomography. Comparison between the groups treated with placebo (n = 30) and histamine (n = 30), on data collected for the 4th, 8th, and 12th weeks of treatment, revealed that histamine exerted a significantly (P < .0001) greater reduction (compared to placebo) in the frequency, intensity, and duration of migraine attacks, as well as on the use of rescue medication. No significant (P > .05) adverse experiences or side effects in either group developed to impede the blinding of the study or the planned order of events. We conclude that the subcutaneous administration of histamine (at very low doses) constitutes a novel and effective therapeutic approach in migraine prophylaxis, aimed at limiting excessive inflammatory responses involved in the pathophysiology of migraine through the activation of H3 receptors.
[DEXA (dual-energy x-ray absorptiometry) and DPA (dual photon absorptiometry) in densitometry of the femoral neck: correlation of the measurements of three commercially available instruments]. (1991)

The bone mineral density measurements of three different instruments at the femoral head were compared using 12 cadaver specimens. Two of these instruments were operated by x-rays (dual energy x-ray absorptiometry = DEXA), whereas one system was based on a gadolinium source (dual photon absorptiometry = DPA). Although excellent correlation between the measurements was obtained (r greater than 0,9), the measurements of one of the DEXA-instruments were significantly higher than the measurements of the two other systems. We conclude that a comparison of bone mineral density measurements obtained on different densitometry instruments may pose problems. Follow-up examinations should be done on one single densitometry unit.
