Influence of ac ageing on space charge dynamics in LDPE
No full textPolymeric materials have been widely used as insulation in power industry due to their excellent electrical properties. However, these properties deteriorate in time irreversibly when the material is subjected to electric stress. Although space charge is believed to play an important role in ac ageing, exact mechanisms are poorly understood due to very limited experimental data. In the present work efforts have been made to investigate the influence of ac ageing on space charge dynamics in low-density polyethylene (LDPE). LDPE films with 200mm were aged at 50 kV/mm at 50 Hz for various times at ambient temperature. Space charge dynamics in the samples prior to and after ageing were monitored using the pulsed electroacoustic (PEA) technique under dc electric stress. The results indicate that there is a significant amount of homocharge accumulation in the unaged sample due to charge injection. These injected charges are the captured by the deep traps originated from the interface between crystalline and amorphous regions in LDPE. Ageing under ac condition does not necessarily lead to an increase in amount of charge in the bulk but leads to an increase in mobility of charge carriers. Chemical analysis by infrared spectroscope (FTIR) reveals there are chemical changes taken place in the bulk of the material after ac ageing. It is believed that the chemical changes introduce shallow traps which promote the movement of charge carriers in the bulk. Consequently, the injected charges spread across the sample
UV Raman Excitation Profiles of Imidazole, Imidazolium, and Water
No full textination of periods of low magnetic field strength, during which the radial Lorentz force is insufficient to retard the radial diffusion of ions and electrons in the plasma. In addition to increasing analyte line-to-background intensity ratios, the hotter plasma core associated with the unidirectional discharge should be useful in the analysis of refractory solid powder samples. Preliminary studies t4 have indicated that the graphite vapor theta-pinch plasma may be useful for the direct analysis of solid powders. The principal problem associated with the present unidirectional discharge system is the limitation to operation at 6 kV or less. This situation should be corrected by the use of fast-recovery diodes. Alternatively, a discharge circuit based on a distributed-element LC transmission line should be capable of producing unidirectional, nearly square-wave current pulses without the use of a diode shunt. A low-voltage prototype circuit has produced very encouraging results. 1. S. R. Goode and D. T. Pipes, Spectrochim. Acta 36B, 925 (1981). 2. G. J. Kamla and A. Scheeline, Anal.

Structural investigation of resorcinol based symmetrical banana mesogens by XRD, NMR and polarization measurements
No full textRestricted Access.Synthesis and structural characterization of two novel symmetrical banana mesogens built from resorcinol with seven phenyl rings linked by ester and imine with a terminal dodecyl/dodecyloxy chain has been carried out. Density functional theory (DFT) has been employed for obtaining the geometry optimized structures, the dipole moments and 13C NMR chemical shifts. The HOPM and DSC studies revealed enantiotropic B2 and B7 phases for the dodecyl and dodecyloxy homologs respectively. The powder X-ray studies of both the mesogens indicate the presence of layer ordering. The polarization measurements reveal an anti-ferroelectric switching for the B2 phase of the dodecyl homolog whose structure has been identified as SmCSPA. The B7 phase of the dodecyloxy homolog was found to be non-switchable. High resolution 13C NMR study of the dodecyl homolog in its mesophase has been carried out. 13C–1H dipolar couplings obtained from the 2-dimensional separated local field spectroscopy experiment were used to obtain the orientational order parameters of the different segments of the mesogen. Very large 13C–1H dipolar couplings observed for the carbons of the central phenyl ring (9.7–12.3 kHz) in comparison to the dipolar couplings of those of the side arm phenyl rings (less than 3 kHz) are a direct consequence of the ordering in the banana phase and the shape of the molecule. From the ratio of the local order parameter values, the bent-angle of the mesogen could be determined in a straight forward manner to be 120.5
Structural, ferroelectric and piezoelectric properties of chemically processed, low temperature sintered piezoelectric BZT–BCT ceramics
No full text0.5Ba(Zr0.2Ti0.8)O3–0.5(Ba0.7Ca0.3TiO3) nanopowders were synthesized at very low temperature using a soft chemical approach. The synthesized powders and the consolidated disks were structurally characterized thoroughly by XRD, SEM, TEM and EPMA and also by ultraviolet and Raman spectroscopy. The 1350 °C sintered BZT–BCT disk displayed the highest density, underwent diffused phase transition centered at ~100 °C and showed the highest dielectric constant (8917) and lowest dielectric loss (0.015). The sintered BZT–BCT sample with the highest density showed a maximum polarization (P max) of 13 μC cm–2 and remnant polarization of 6 μC cm–2. The same sample exhibited very high electrostrain of ~0.12% under a relatively low electrical field of 3.5 kV mm−1
Semiconductor/relaxor 0–3 type composites: a novel strategy for energy storage capacitors
No full textIn this work, we report a novel strategy to enhance the dielectric breakdown strength and the energy storage performance of lead-free relaxor ferroelectric ceramics through the fabrication of semiconductor/
relaxor 0e3 type composites based on 0.6Ba(Zr0.2Ti0.8)O3-0.4(Ba0.7Ca0.3)TiO3 [BZCT] and ZnO. X-ray
diffraction (XRD), Raman spectroscopy and scanning electron microscopy (SEM) measurements confirm
the formation of semiconductor/relaxor 0e3 type composites, in which ZnO particles are randomly
distributed at the grain boundaries of BZCT. Further, the XRD analysis suggests a structural phase change
from a tetragonal to a pseudocubic phase as the ZnO content increases from 0 to 5 wt. % in BZCT/ZnO
composites. The pseudocubic phase favors the relaxor behavior of the composites as is evident from
dielectric studies. The polarization-electric field (P-E) loops reveal the ferroelectric nature of the BZCT/
ZnO composites. The energy storage properties of BZCT/ZnO composite ceramics as a function of different
wt. % of ZnO are found to be optimum at 1 wt. % with a recoverable energy density of 2.61 J/cm3 and an
efficiency of 74.2%, at an electric field of 282 kV/cm. Besides, an enhancement of 166% in the electric
breakdown and 220% in the recoverable energy density was achieved compared to the BZCT ceramics
due to the improved density and the large value of DP ¼ Pm - Pr (25.55 mC/cm2
). Therefore, this work
evidences that the formation of semiconductor/relaxor 0e3 type composites can be an effective way to
significantly improve the energy storage performance of lead-free relaxor ferroelectric ceramics.This study has been partially supported by (i) DST-SERB, Govt. of

Protein Folding and Macromolecular Dynamics: Fundamental Limits of Length and Time Scales
Get PDFIn this thesis, physics-based models of protein folding at the secondary and tertiary level are developed to resolve long-standing issues of protein folding kinetics. As discussed in the Introduction, the main objective is to provide fundamental limits on the length and time scales involved in protein folding. Protein folding is also placed within the broader context of macromolecular dynamics, which is extensively studied in the unfolded, folded, and unfolding regimes for the key molecular motifs of cellular biochemistry, including lipids, nucleic acids, and proteins. The effect of the water hydration and temperature are systematically probed to elucidate the crucial role of the environment in macromolecular stability and dynamics. For a wide range of bio-molecular phenomena, the observed collective behavior is shown to arise directly from first principles. Throughout, the emphasis is on analytic results free of tunable parameters, supported by ensemble-converging computational simulations, and corroborated by experimental evidence
Interobserver reliability of rheumatologists performing musculoskeletal ultrasonography: results from a EULAR ''Train the trainers'' course
Get PDFObjective: To evaluate the interobserver reliability among 14 experts in musculoskeletal ultrasonography ( US) and to determine the overall agreement about the US results compared with magnetic resonance imaging (MRI), which served as the imaging "gold standard''. Methods: The clinically dominant joint regions ( shoulder, knee, ankle/toe, wrist/finger) of four patients with inflammatory rheumatic diseases were ultrasonographically examined by 14 experts. US results were compared with MRI. Overall agreements, sensitivities, specificities, and interobserver reliabilities were assessed. Results: Taking an agreement in US examination of 10 out of 14 experts into account, the overall kappa for all examined joints was 0.76. Calculations for each joint region showed high kappa values for the knee ( 1), moderate values for the shoulder ( 0.76) and hand/finger (0.59), and low agreement for ankle/toe joints (0.28). kappa Values for bone lesions, bursitis, and tendon tears were high (kappa = 1). Relatively good agreement for most US findings, compared with MRI, was found for the shoulder ( overall agreement 81%, sensitivity 76%, specificity 89%) and knee joint ( overall agreement 88%, sensitivity 91%, specificity 88%). Sensitivities were lower for wrist/finger ( overall agreement 73%, sensitivity 66%, specificity 88%) and ankle/toe joints ( overall agreement 82%, sensitivity 61%, specificity 92%). Conclusion: Interobserver reliabilities, sensitivities, and specificities in comparison with MRI were moderate to good. Further standardisation of US scanning techniques and definitions of different pathological US lesions are necessary to increase the interobserver agreement in musculoskeletal US.

This shrinking donor pool has prompted reassessment of donor selection for heart transplantation. Bench repair of a donor aortic valve was performed before minimal access orthotopic heart transplantation. Aortic insufficiency in the structurally normal tricuspid aortic valve was due to annular dilatation and was corrected with subcommissural annular plication. The postoperative period was uneventful. Follow-up at 4.5 years showed good results and no evidence of aortic regurgitation. (c) 2005 by The Society of Thoracic Surgeons.

The dose range varied from 59 to 63 Gy in post-operative patients and 65 Gy to 71 Gy in curative patients. Results: Five-year Overall Survival (OS) and Disease-Free Survival (DFS) for patients treated with irradiation alone and for those treated with post-operative radiotherapy were 50.8% and 69.7%, respectively, without significant statistical difference. For OS multivariate analysis showed statistical difference for stage and age variables, and for stage variable in the case of DFS. Conclusion: In early stage vulvar cancer patients OS and DFS are good, with high control rate and low incidence of adverse effect. In loco-regionally-advanced patients, especially in those with stage IV or with > 2 positive lymph nodes, the outcomes are poor.

When an incoming electromagnetic field illuminates the obstacle a scattered field is generated. A smart obstacle is an obstacle that in the scattering process, circulating a surface electric current density on its boundary, tries to achieve a given goal. We consider four possible goals: making the obstacle undetectable (i.e.: furtivity problem), making the obstacle to appear with a shape and impedance different from its actual ones (i.e.: masking problem), making the obstacle to appear in a location different from its actual one eventually with a shape and impedance different from its actual ones (i.e.: ghost obstacle problem) and finally one of the previous goals limited to a given subset of the frequency space (i.e.: definite band problems). We consider the problem of determining the optimal electric current density to achieve the given goal. The relevance in many application fields (i.e. stealth technology, electromagnetic noise control, etc.) of these problems is well known. The previous problems are modelled as optimal control problems for the Maxwell equations. Some numerical results on test problems obtained solving the optimal control problems proposed are shown.

An electrically induced temperature increase is responsible for the change of the refractive indices of the layers. As a result, the reflection spectrum shifts and the reflected signal decreases. The structure was grown using a thermal evaporation technique, and was designed in such a way that a band edge appears at 632.8 nm, i.e. accessible to a low-power He-Ne laser. The reflection characteristics were investigated as a function of the applied voltage and we found that the photonic band edge shifts by a maximum of 7 nm for an applied voltage of 90 V. Furthermore, different sets of measurements have shown that the spectral shift depends on the voltage squared, thus allowing experimental data analysis in terms of the thermally driven optical nonlinearity.

A nonlinear coefficient of about 120 W-1 km(-1) is achieved at the wavelength of 670 nm for a fused-silica fiber with a full hexagonal cycle of closely packed air holes around the fiber core. The removal of a single element from this array of air holes is shown to frustrate field confinement in guided modes, leading to mode leakage.

Optical frequency generation in both second- and third-order nonlinear materials is demonstrated based on the transient evolution of cavity modes. Terahertz waves can be generated in quadratically nonlinear crystals by optical rectification, whereas state generation inside the band gap can be linked to a Rabi-like splitting in cubic media. An all-optical ultra-fast wavelength shifter is proposed.

The mean age was 58 years for men and 59.2 years for women. Intervention: Supracricoid partial laryngectomy: 180 patients had undergone cricohyoidopexy and 73 had undergone cricohyoidoepiglottopexy. Main Outcome Measures: Local control and overall survival. Potential prognostic factors for local control and survival were evaluated with univariate and multivariate models. Results: The 3-, 5-, 10-, and 16-year overall survival rates in this group of 253 patients were 85.8%, 79.1%, 57.6%, and 57.6%, respectively. With regard to local control, univariate and multivariate analyses showed that a positive resection margin was the only important predictor of local control and that a dysplastic lesion at the margin of resection is just as aggressive as the presence of invasive carcinoma. When considering the prognostic factors influencing survival, univariate analysis showed that the tumor category, lymph node category, tumor stage, and recurrence all had a significant influence on the survival rate. Multivariate analysis showed that the most important predictor of survival was recurrence. Conclusions: Supracricoid partial laryngectomy is a valid choice in the treatment of selected glottic and supraglottic cancer while maintaining laryngeal functions and achieving a high rate of local control. T category, N category, tumor stage, positive resection margins, and recurrence are the most important predictors of oncological outcome.

Get PDFGlobal Practice Patterns and Variations in the Medical and Surgical Management of Non-Obstructive Azoospermia: Results of a World-Wide Survey, Guidelines and Expert Recommendations
Get PDFPurpose: Non-obstructive azoospermia (NOA) is a common, but complex problem, with multiple therapeutic options and a lack of clear guidelines. Hence, there is considerable controversy and marked variation in the management of NOA. This survey evaluates contemporary global practices related to medical and surgical management for patients with NOA.
Materials and methods: A 56-question online survey covering various aspects of the evaluation and management of NOA was sent to specialists around the globe. This paper analyzes the results of the second half of the survey dealing with the management of NOA. Results have been compared to current guidelines, and expert recommendations have been provided using a Delphi process.
Results: Participants from 49 countries submitted 336 valid responses. Hormonal therapy for 3 to 6 months was suggested before surgical sperm retrieval (SSR) by 29.6% and 23.6% of participants for normogonadotropic hypogonadism and hypergonadotropic hypogonadism respectively. The SSR rate was reported as 50.0% by 26.0% to 50.0% of participants. Interestingly, 46.0% reported successful SSR in <10% of men with Klinefelter syndrome and 41.3% routinely recommended preimplantation genetic testing. Varicocele repair prior to SSR is recommended by 57.7%. Half of the respondents (57.4%) reported using ultrasound to identify the most vascularized areas in the testis for SSR. One-third proceed directly to microdissection testicular sperm extraction (mTESE) in every case of NOA while others use a staged approach. After a failed conventional TESE, 23.8% wait for 3 months, while 33.1% wait for 6 months before proceeding to mTESE. The cut-off of follicle-stimulating hormone for positive SSR was reported to be 12-19 IU/mL by 22.5% of participants and 20-40 IU/mL by 27.8%, while 31.8% reported no upper limit.
Conclusions: This is the largest survey to date on the real-world medical and surgical management of NOA by reproductive experts. It demonstrates a diverse practice pattern and highlights the need for evidence-based international consensus guidelines

The Simplified Spelling
By l'.'o,-...r BRANOl !< MATTHEWS
CITE adhesion of tbe foremost linguistic, authorities of both
branches of thc Mnglt-.li Bpqgjpng nu--* ought to tie reassuring
to those who hnve dreaded that thc reromtuendations of the
simplified t?pC'lliiig board might work harm to our tongue
nnd etymolog*. It serves to show that thoso who KNOW MOST
about English Kpeliing lielieve it ought. 10 be improved.
Sooner or later what we propose to do is bound to go through. All
thinking people already realize that, uud nothing better could hnve
happened for our movement thun to hare tha president stand on a
hilltop and blow u wgoropa blu-d for un. What wo want to do is to
prousti TIIF. INTEREST OF PEOPLE and make them look into
what we arc really proposing, and the pret-ident's action will do thnt as
nothing oho could.
The president*! order came at an entire surprise to me. I am mire
1 lint I did not even send him any of the documents published by thc
hoard and did not hnve any idea that he wus interested in the subject
even until » requital for our list of recommended spellings was received ;
from Secretary I,oeb.
The next I kno**.' wag the announcement of the «r<)§y in the papers, j
I nm very ghid to find thut the president was more interested in our
elTortx than I supposed, and I feel sure that his indorsement will be of
the great--* t possible benefit to the simplified spelling movement.
The opponent of the movement have said thut many professors of
