Palimkar Anand,Khandekar Rajiv,Venkataraman V
Indian Journal of Ophthalmology , 2008,
Abstract: Purpose: A community-based survey was conducted in Rajnandangaon district of Chhattisgarh state of central India in 2001 to assess the prevalence of glaucoma in the age group of =35 years. Design: Community-based cross-sectional survey Materials and Methods: Ophthalmologists measured ocular pressure using Perkins applanation tonometer. Best corrected visual acuity was checked by ETDRS chart. After dilating the pupil the fundus was examined. A sketch diagram was drawn to note glaucomatous changes in optic disc and the surrounding retina. The field of vision was tested on Bjerrum screen. Gonioscopy was performed to determine type of glaucoma. Persons and their relatives were interviewed to find out risk factors and glaucoma treatment in the past. Results: Seven thousand four hundred and thirty-eight (87.3%) persons were examined. The age-sex standardized prevalence of glaucoma was 3.68% (95% CI 3.27 to 4.07). Gender variation of glaucoma was not significant. [OR = 1.13 (CI 95% 0.88 to 1.44)] Glaucoma varied significantly by age groups. (χ2 = 48.2, degree of freedom = 3 P < 0.001) Among those patients diagnosed to suffer from glaucoma, the proportion of open angle, closed angle, secondary glaucoma, ocular hypertension and glaucoma suspects was 13.1%, 21.2%, 21.2%, 14.5% and 30% respectively. Different types of visual disabilities were associated with glaucoma. However, unilateral blindness in glaucoma was unusual. Twenty-five per cent of the glaucoma cases were detected for the first time during the survey. Conclusions: The prevalence of glaucoma was high and the angle closure type was more compared to the open angle glaucoma.
The Role of Electric Field and Ultrasonication in the Deposition and Alignment of Single-Walled Carbon Nanotube Networks Using Dielectrophoresis  [PDF]
S. Ammu, D. Heskett
World Journal of Condensed Matter Physics (WJCMP) , 2013, DOI: 10.4236/wjcmp.2013.34025
Abstract:

The effects of electric field and ultrasonication on the deposition and alignment of single-walled carbon nanotubes (SWCNTs) across a 10 μm electrode gap have been studied. It was found that a frequency of ~1 MHz of the applied field yields the largest current independent of the magnitude of the voltage or the ultrasonication time of the sample. Increasing the ultrasonication time of a SWCNT solution changes the I-V characteristics of the deposited nanotubes from linear to nonlinear for all the voltages and frequencies of the applied field. Even in the absence of an electric field, SWCNTs bridged the electrode gap up to a critical sonication time which depends on the concentration of nanotubes in the solution.

S. Suresh, D. Arivuoli
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2011, DOI: 10.4236/jmmce.2011.106039
Abstract: Non-linear optical materials find wide range of applications in the fields of opto-electronics, fiber optic communication, computer memory devices etc. Tris-Glycine Zinc Chloride (TGZC) is one of the NLO materials exhibiting more efficiency. In the present study Tris-Glycine Zinc Chloride were grown is single crystal form using slow evaporation technique. Single crystal X-ray diffraction analysis reveals that the crystal belongs to orthorhombic system with the space group Pbn21. The optical absorption studies show that the crystal is transparent in the entire visible region with a cut off wavelength of 250 nm. The optical band gap is found to be 4.60 eV. The dependence of extinction coefficient (K) and refractive index (n) on the wavelength has also been reported. Force constants (k) were calculated using FTIR spectral analysis which shows higher values of k for COO and C=O stretching vibrations. The dielectric studies show that the dielectric constant and dielectric loss decrease exponentially with frequency at different temperatures (35℃, 55℃, 75℃ and 95℃).

S. Chinnapparaj, D. Somasundareswari
Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.79213
Abstract: Improvement of digital FIR filter is vital in the field of Digital Signal Processing in order to reduce the area, delay and power. Multiplication and Accumulation (MAC) unit of Finite Impulse Response？(FIR) filter has been designed using efficient multiplier and adder circuits for optimized APT (Area,Power and Timing) product. In this paper, the design of direct form FIR filter with efficient MAC unit has been presented. Initially, full adder and half adder structures are shrunk down by reducing number of gates. These compact full adder and half adder structures are incorporated into Wallace Multiplier and Improved Carry-Save Adder. The proposed 16-bit Carry-Save Adder has been improved by splitting into four parallel phases. Consequently the delay of enhanced Carry- Save Adder is reduced. Generation of carry output is performed using number of OR gates in a sequential manner. All these enhanced architectures are incorporated into the Digital FIR Filter to reduce the area, delay and power utilization.

S. G. D. Gangadaran
Advances in Breast Cancer Research (ABCR) , 2016, DOI: 10.4236/abcr.2016.54015
Abstract: Introduction: Quality assurance is an essential aspect of cancer care. Assessment of surgical quality in breast cancer is still evolving. Variability in surgical care among surgeons has been well documented in literature and we sought to investigate such variation between two groups of surgeons referring patients to our oncology center. Methods: A prospective review of patient records of all breast cancer referrals to our department was made. Two groups were identified and segregated based on the performance of mastectomy by a general surgeon (GS) or by a surgical oncologist (SO). Patients treated with modified radical mastectomy for clinical stages 1 - 3 were included for the study. Patient demographic data and disease related information were collected in addition to thorough evaluation of the surgical pathology report. Margin positivity, mean nodal harvest, nodal ratio, inadequate axillary clearance, revision surgery and the use of radiotherapy for inadequate nodal dissection were the parameters evaluated in the study. Results: A total of 142 patient records were evaluated 72 designated as group 1 (general surgeons) and 70 as group 2 (surgical oncologist). The median age was 52 years and both groups were evenly balanced for age, laterality of breast lesion, histological type and grade. The mean nodal harvest was 8 vs. 14 nodes, and significant differences were observed in favor of surgical oncology group in margin positivity (P = 0.01), inadequate axillary clearance (P

S. Sivakumar, D. Nedumaran
Journal of Applied Mathematics and Physics (JAMP) , 2018, DOI: 10.4236/jamp.2018.69163
Abstract: This paper presents the methodology, properties and processing of the time-frequency techniques for non-stationary signals, which are frequently used in biomedical, communication and image processing fields. Two classes of time-frequency analysis techniques are chosen for this study. One is short-time Fourier Transform (STFT) technique from linear time-frequency analysis and the other is the Wigner-Ville Distribution (WVD) from Quadratic time-frequency analysis technique. Algorithms for both these techniques are developed and implemented on non-stationary signals for spectrum analysis. The results of this study revealed that the WVD and its classes are most suitable for time-frequency analysis.

Beijing Law Review (BLR) , 2019, DOI: 10.4236/blr.2019.104045
Abstract: With development of industries and a welcome to the era of globalization along with information technology, many software companies came into being. Tech and tech experts made it easier to pirate the software of the producers. Problems to the customer as well as to the content owner are present. One of major lacunas is the Judiciary being indecisive with the adamant growth of digital world as to the punishment and the reduction of crime, no separate laws by the legislators to protect the software piracy as a distinct crime. Lack of enforcement mechanism by the executive and administrative bodies leads to the increase of piracy in software.
