Numerical Simulation Analysis of Temperature Field on Tympanites Roadbed (2013)

The physical model and calculating model of temperature field are founded according to the founded controlling equation. By simulating the changing progress of climate features, the temperature field of roadbed in permafrost region in different season was obtained. And some results are got by analyzing the diversity of temperature of key points. The last, the technology assumption of effectively controlling tympanites which combines replacing part frozen soil and resisting highway tympanites structure is brought up.
Challenges and trends in optical networking: A bottom-up approach (2008)

Future bandwidth-intensive services, which will have a wide impact on our daily lives, from entertainment, to business and health-care, demand high capacity, flexible, resilient and secure underlying networks. Simultaneously, rising energy costs and climate change concerns are increasing the pressure to adopt power-efficient solutions in communication networks. Most of these requirements are best fulfilled with optical networks, which are expected to provide the targeted high capacities together with an increasing number of functionalities, leaving behind the label of ldquodumb piperdquo associated to them in early deployments. This paper presents an overview of the challenges and some of the trends in optical networking, covering developments in multiple layers of the protocol stack, from the physical up to the application layer, and aimed at different network segments, from the access to the core network.
Suzaku observations of Jovian diffuse hard X-ray emission (2021)

Abstract We report on results of systematic analyses of the entire three X-ray data sets of Jupiter taken by Suzaku in 2006, 2012, and 2014. Jovian diffuse hard X-ray emission was discovered by Suzaku in 2006 when the solar activity went toward its minimum. The diffuse emission was spatially consistent with the Jovian inner magnetosphere and was spectrally fitted with a flat power-law function suggesting non-thermal emission. Thus, a scenario in which ultra-relativistic (tens of MeV) electrons in the Jovian inner magnetosphere inverse-Comptonize solar visible photons into X-ray bands has been hypothetically proposed. We focused on the dependence of the Jovian diffuse hard X-ray emission on the solar activity to verify this scenario. The solar activity in 2012 and 2014 was around the maximum of the 24th solar cycle. By combining the imaging and spectral analyses for the three data sets, we successfully separated the contribution of the diffuse emission from the emission of Jupiter’s body (i.e., the aurora and disk emission). The 1–5 keV luminosity of the diffuse emission has been stable and did not vary significantly, and did not simply depend on the solar activity, which is also known to affect the high-energy electron distribution in the Jovian inner magnetosphere scarcely. The luminosity of the body emission both in 0.2–1 and 1–5 keV, in contrast, probably depended on the solar activity and varied by a factor of 2–5. These results strongly supported the inverse-Compton scattering scenario by the ultra-relativistic electrons. In this paper, we estimate spatial and spectral distributions of the inverse-Compton scattering X-rays by Jovian magnetospheric high-energy electrons with reference to the Divine–Garrett model and found a possible agreement in an inner region (≲10 RJ) for the X-ray observations.

Aging of the population is a concern in the near future for a significant fraction of countries worldwide. While in several members of the European Union having people over 60 largely outnumbering newborns is a reality, this is now predicted to occur also in Asia, and in the near future, elderly people will represent more than a fourth of the global population. Such predictions prompt to address the linked healthcare challenge in time and efforts in defining new treatments for the diseases of the elderly are currently under intense investigation. It is along this line that the Myocardial Function and Cellular Biology Working Groups of the European Society of Cardiology gathered in the biannual Varenna meeting in the spring of 2015. This conference entitled ‘Salvage Pathways in Heart Rejuvenation’ intended to provide the latest findings in cardiovascular …
RP-HPLC Analysis of the Phenolic Compounds of Plant Extracts. Investigation of Their Antioxidant Capacity and Antimicrobial Activity (2005)

Extracts of aromatic plants of Greek origin were examined as potential sources of phenolic compounds. RP-HPLC with UV detection was employed for the identification and quantification of the phenolic antioxidants, present in methanolic extracts. The most abundant phenolic acids were ferulic acid (1.1-280 mg/100 g of dry sample) and caffeic acid (1.2-60 mg/100 g of dry sample). (+)-Catechin and quercetin were the most abundant flavonoids. Apigenin and luteolin were detected in high amounts in Menta pulegium and Thymus vulgaris, respectively. The antioxidant capacity was determined, in dried ground plants and in their methanol extracts, with the Rancimat test using sunflower oil as substrate. Both pulverized plants and extracts showed antioxidant capacity. Total phenolic content in the extracts was determined spectrometrically according to the Folin-Ciocalteu assay and ranged from 1 to 21 mg of gallic acid/100 g of dry sample. Antimicrobial activity of the extracts against selected microbes was also conducted in this study.

Groundwater Inspection in Coastal Aquifers Using MT and AMT Methods (2005)

B038 Groundwater Inspection in coastal aquifers using MT and AMT Methods Summary 1 In the framework of the SWIMED Salt Water Intrusion European Project the coastal aquifers of Muravera south-western Sardinia have been studied. Intensive agricultural and tourist activities have exploited these aquifers in the past. Since few years a salt-water intrusion happens mainly caused by a recurring lasting drought by aquaculture system and by intensive rice growing. Geophysical studies performed in past in the same area showed deep geological structures and placed questions about 300 meters deep groundwater conditions. In Muravera plain Gravimetric Seismic and TDEM Electromagnetic surveys have
Piston Ring Pack Friction and Lubrication Analysis of an Automotive Engine Using a Mixed Lubrication Model (1993)

&lt;div class="htmlview paragraph"&gt;A ring pack friction model has been developed based on the mixed lubrication concept to investigate the effects of ring surface topology on ring/liner interfacial frictions. The simulated friction results were verified by using the moving liner test rig and good correlations were established. The developed model was then extended to simulate the ring pack frictions under engine firing conditions. Surface roughness pattern oriented in the transverse, isotropic, and longitudinal directions were analyzed. The results indicate that the influence of surface pattern on ring pack friction is very substantial. A reduction of 9 percent of the ring pack friction is observed simply due to the surface pattern change. Friction reduction is a result from an increase in film thickness. This also helps to decrease the friction spikes near the dead centers and reduce ring wear. An increase in surface roughness magnitude significantly increases the ring pack friction. The mixed lubrication zone is also extended, and the oil ring friction is observed to be the most sensitive to surface roughness variations.&lt;/div&gt;
Localization of wood floor structure by infrared thermography (2008)

One of our industrial partners, Assek Technologie, is interested in developing a technique that would improve the drying process of wood floor in basements after flooding. In order to optimize the procedure, the floor structure and the damaged (wet) area extent must first be determined with minimum intrusion (minimum or no dismantling). The present study presents the use of infrared thermography to reveal the structure of (flooded) wood floors. The procedure involves opening holes in the floor. Injecting some hot air through those holes reveals the framing structure even if the floor is covered by vinyl or ceramic tiles. This study indicates that thermal imaging can also be used as a tool to validate the decontamination process after drying. Thermal images were obtained on small-scale models and in a demonstration room.
Glycosyl-phosphatidylinositol anchor synthesis in paroxysmal nocturnal hemoglobinuria: partial or complete defect in an early step (1994)

The defect in the biosynthesis of the glycosyl-phosphatidyl inositol (GPI) anchor in paroxysmal nocturnal hemoglobinuria (PNH) appears to be in the initial steps. In biosynthetic studies using [3H]mannose, abnormal granulocytes of eight patients, and B lymphocytes transformed by Epstein-Barr virus of six different patients synthesized dolichyl phosphoryl mannose, but little or no later mannosylated intermediates. When fused with murine cell lines known to be deficient at different biosynthetic steps of the GPI anchor, the GPI-anchor-deficient granulocytes of 21/21 patients and lymphocytes from 6/6 patients complemented all murine cell lines except those of class A; cells of this class are not able to add N-acetylglucosamine to phosphatidylinositol. These studies indicate that the defect in GPI-anchor synthesis in PNH is early in the pathway, and is the same as that of class A mutants, but may be partial in some patients, resulting in the production of small amounts of mannosylated intermediates.

Comparison of Homoepitaxial Growth of YBa2Cu3Oy Films on Variously Oriented YBa2Cu3Oy Single Crystals (1997)

Microstructures at interfaces of YBa 2 Cu 3 O y (YBCO) thin films homo-epitaxially grown on (001), (100), and (110) oriented YBCO single crystals by RF sputtering and metalorganic chemical vapor deposition (MOCVD) have been studied by transmission electron microscopy. In the case of a (001) YBCO single crystal substrate the orientation of an YBCO thin film grown by RF sputtering depends on the substrate temperature, similar to the case for normal substrates. In the case of a 2° off-cut (001) YBCO substrate grown by MOCVD, no difference of structure between the thin film and the substrate can be distinguished except for a one-unit-cell difference at the interface. When homo-epitaxy is carried out on a (100) YBCO single crystal, a high quality a -axis YBCO thin film can be obtained by either MOCVD or sputtering. Differences in microstructures for (100) and (001) homo-epitaxy are discussed in terms of the layered structure of YBCO as well as differences in growth modes.

A Controllable 45-kW Current Source for DC Machines (1979)

A new type of dc converter for the drive and control of a 45-kW traction motor in single quadrant operation with an efficiency of 96 percent is presented. An improvement of the converter's reliability is due to the natural termination of thyristor currents, the positive confinement of the maximum momentary current and voltage stresses in the components below preset levels, and the low power dissipation in these components, supported by a definite protection philosophy. The high converter efficiency is attained at full power operation with an internal frequency of 10 kHz. The input impedance maintains its resistive character for all conditions of operation. The output port is characterized as a voltage-limited current source. Test data of an experimental model conclude the presentation of the converter's functional philosophy.
Influence of al doping agents nature on the physical properties of Al:ZnO films deposited by spin-coating technique (2015)

In this paper we present the morphological, structural, optical and electrical properties of aluminium doped zinc oxide films prepared by spin coating technique from a zinc acetate dihydrate and 2-methoxyethanol (0.5M) solution. AlCl(3) and Al(NO(3))(3) were used as doping agents in different concentrations (1at%, 4at% and 6at% in starting solution). After deposition, films were dried at 100 degrees C and then annealed at temperatures between 400 degrees C and 500 degrees C. The characterization of deposited layer was performed by Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM) and UV-Vis spectroscopy. The results show that the optical and electrical properties of the structures strongly depend on the deposition conditions of ZnO:Al. In addition, the resistivity can be easily varied depending on ZnO:Al annealing temperatures and Al concentration
Tissue Engineering and Regenerative Medicine in Craniofacial Reconstruction and Facial Aesthetics (2019)

The craniofacial region is anatomically complex and is of critical functional and cosmetic importance, making reconstruction challenging. The limitations of current surgical options highlight the importance of developing new strategies to restore the form, function, and esthetics of missing or damaged soft tissue and skeletal tissue in the face and cranium. Regenerative medicine (RM) is an expanding field which combines the principles of tissue engineering (TE) and self-healing in the regeneration of cells, tissues, and organs, to restore their impaired function. RM offers many advantages over current treatments as tissue can be engineered for specific defects, using an unlimited supply of bioengineered resources, and does not require immunosuppression. In the craniofacial region, TE and RM are being increasingly used in preclinical and clinical studies to reconstruct bone, cartilage, soft tissue, nerves, and blood vessels. This review outlines the current progress that has been made toward the engineering of these tissues for craniofacial reconstruction and facial esthetics.
A case study on the comparison of non-parametric spectrum methods for broken rotor bar fault detection (2004)

Broken rotor bars in an induction motor create asymmetries and result in abnormal amplitude of the sidebands around the fundamental supply frequency and its harmonics. Applying a spectrum analysis technique on motor current and inspecting the spectrum amplitudes at the broken rotor bar specific frequencies for abnormality is a well-known procedure for broken rotor bar fault detection and diagnosis. Among the spectrum analysis techniques for broken rotor bar fault detection, the fast Fourier transform (FFT) is the most widely used technique. There are other spectrum techniques, which are based on the power spectral density estimates. In this paper we compare the three well-known spectrum analysis methods: FFT, periodogram and Welch's periodogram methods according to their performance on the broken rotor bar fault detection problem. The results indicate that Welch's periodogram method has better fault discrimination capability and is more robust compared to the other two methods. A statistical hypothesis test applied to the results of the three methods depicts the comparison results quantitatively.

Stimulation of drop coalescence with acoustic cavitation (1991)

A standing acoustic field was used to levitate a pair of anisole (methoxybenzene) drops in an aqueous surfactant solution containing Teflon particles to act as cavitation nuclei. The drops were brought into contact with each other by the levitation field but did not coalesce immediately because of the surfactant in the water. By increasing the intensity of the sound field, cavitation events were produced, some of which ruptured the oil/water interface, causing plumes of micron-sized oil droplets to be expelled from one of the main drops. Occasionally, this disturbance caused the main drops to coalesce. This method of stimulating coalescence was studied using high-speed film and statistical analysis, which will be reviewed in the presentation. [Work supported by NASA through JPL, Contract 958722.]
An acoustic comparison of dental and retroflex sibilants in Chinese Mandarin and Taiwan Mandarin (2014)

Mandarin has both dental and retroflex sibilants. While the Mandarin varieties spoken in China and Taiwan are often considered the same, native speakers of Mandarin can tell the difference between the two. One obvious difference is that between the retroflex ([ʂ], [tʂ], [tʂh]) and dental sibilants ([s], [ts], [tsh]). This study investigates the acoustic properties of the sibilants of Chinese Mandarin and Taiwan Mandarin. Eight native speakers each of Chinese and Taiwan Mandarin produced the six target sibilants in word-initial position. A number of acoustic parameters, including spectral moments and duration, were analyzed to address two research questions: (a) which parameters distinguish the dental and retroflex in each type of Mandarin; (b) is there a difference between Chinese and Taiwan Mandarin? Results show that retroflex sibilants have a lower M1 and M2, and a higher M3 than dental sibilants in each language. Moreover, Chinese Mandarin has significantly larger M1, M2, and M3 differences than Taiwan Mandarin. This pattern suggests that, in contrast to Chinese Mandarin, Taiwan Mandarin is merging the retroflex sibilants in a dental direction.

Ethylcyanoacetate Derivatives of Ruthenium (1986)

Abstract Seven novel ethylcyanoacetate-ruthenium complexes have been prepared. These include four addition complexes, RuHClCO (PPh3)2 (LH), RuCl2 (PPh3)2 (LH)2, RuCl3 (LH)24H2O and Ru3 (CO)8 (LH)4 [where LH = ethylcyanoacetate], and three Ru-C σ bonded complexes obtained from the reaction between the chloro-ruthenium complexes RuHClCO (PPh3)3 and RuClCp (PPh3)2 and the sodium derivative of ethylcyanoacetate, NC-CH (Na)COOC2H5, or by the hydrogenolysis of RuHCp (CO)2 and RuHCp (PPh3)2 with LH [where Cp = η5-C5H5]. These complexes have been studied by their spectral characteristics and the possible stereochemistry is discussed.
