Efficient Method of Removing the Noise using High Dynamic Range Image

Various tone mapping methods have been proposed to make the image better concurrent to human visual observation. In general, tone mapping can also be carried in nearby and/or world features. In this work, a progressive tone mapping framework such as wavelet filter and spongy thresholding is proposed to diminish the noise this 4% quicker than may shrink process. It's one of a kind curve centered universal tone mapping methods that increase the bright and darkish regions. Peak Signal Noise Ratio (PSNR) value is calculated to know the enrichment value. Simulation outcome shows that the proposed schemes achieve high contrast improvement

Study on outcome of N-acetylcysteine in rodenticide poisoning cases in a rural tertiary care teaching hospital

Background: Rodenticide is one of the pesticides and heterogeneous substances used to kill rats. Rodenticide poisoning is the major health problem in Asian countries, particularly mode of self-poisoning, prevalent in India. It causes hepatotoxicity and no antidote has been found. N-acetylcysteine (NAC) is a powerful antioxidant and used in the treatment of acetaminophen-induced hepatotoxicity.  The aim of the study is to find the outcome of use of NAC in rodenticide poisoning.  The main objectives of this study were to determine the role of NAC in liver impairment rodenticide poisoning patients.   Methods: A record based observational study was conducted for the period of 3 months from August 2019 to October 2019 at Rajah Muthiah Medical College and Hospital, Annamalai University, Annamalai Nagar, Tamil Nadu. Data were collected according to the proforma designed and results were analyzed using standard methods.Results: Out of 50 patients, 21 (42%) were males and 29 (58%) were females. Age group between 21-30 years contributes the highest 20 (40%). Majority of type of rodenticide compound consumed by patients were paste 29 (58%) and less than four hours 34 (68%) patients were admitted. Patients with abnormal liver functions were tested, serum glutamic oxaloacetic transaminase/ aspartate aminotransferase -12 patients, 7 treated with NAC. serum glutamic pyruvic transaminase/ alanine aminotransferase - 9 patients, 2 treated with NAC. 37 (74%) were recovered out of 50 (100%), among them 28 (56%) treated with NAC.Conclusions: In liver impairment rodenticide poisoning patients, early use of NAC shows a significant result and the rate of recovery is also high

DEVELOPMENT AND STUDY OF GSH CAPPED CdTe QUANTUM DOTS EMBEDDED POLYMER ELECTROSPUN NANOFIBERS

ABSTRACT Quantum Dots (QDs) can be synthesised by chemical method under normal atmosphere. Chemical methods are found to be more economical of all methods, which led to the interest to synthesis QDs through chemical route. The present work focuses the preparation of cadmium Telluride (CdTe) QDs and the formations of CdTe QDs-PVA (poly vinyl alcohol) nanofiber by electrospinning method. The absorption and emission spectra of UV-Visible and Photoluminescence (PL) characterisation confirms the presence of CdTe QDs. The surface morphology and uniformity of CdTe QDs and PVA matrix nanofiber was confirmed through SEM images

Ethyl 1-benzene­sulfonyl-2-[(E)-2-(2-methyl­phen­yl)ethen­yl]indole-3-carboxyl­ate

In the title compound, C26H23NO4S, the phenyl, tolyl and ester groups make dihedral angles of 82.28 (5), 77.67 (6) and 8.52 (6)°, respectively, with the indole ring system. The S atom of the sulfonyl group is displaced by 0.1968 (4) Å from the indole mean plane. The mol­ecular structure is stabilized by weak intra­molecular C—H⋯O inter­actions. The crystal structure structure features short intramolecular C—H⋯O contacts and π–π stacking inter­actions between the phenyl and tolyl groups [centroid–centroid distance = 3.9448 (11) Å]

Physico-Chemical and Bacteriological Characteristics of Noyyal River and Ground Water Quality of Perur, India

The study was conducted to findout the physico-chemical and bacteriological characteristics of Noyyal River and ground water quality of Perur, India. The river water and ground water (bore well and open well) samples were collected in and around Perur and analyzed for various physico-chemical and bacteriological parameters. The study indicated that the mean value of studied parameters, except phosphate, biological oxygen demand (BOD), chemical oxygen demand (COD) of the river water and ground water samples were within the permissible limit. The parameters include total suspended solids (TSS-132.2 mgl-1), BOD (9.55 mgl-1), COD (19.28 mgl-1), phosphate (PO42--1.58 mgl-1) and total nitrogen (TN-2.04 mgl-1) of the river water sample were found higher when compared to the ground water samples. The bacteriological study showed that the total heterotrphic bacteria (THB -124.4 x 103 CFU/ml), Total Coliforms (TC-2600 MPN/10ml), Faecal Coliforms (FC-1750 MPN/10ml), Faecal Streptococci (FS-120 MPN/10ml) and FC/FS ratio (14.6) in the river water samples were found to be greater than the standard WHO limits. The generic distribution in the samples revealed that the presence of Escherichia coli , Staphylococcus, Enterobacter, Streptococci, Bacillus and Micrococcus were predominant in river water samples. The river water was found to be unfit for human consumption due to the exceeding level of Coliforms. The quality of ground water around Noyyal River was found to be safe and utilizable for cultivation purposes. If the quality management is properly maintained, the river water could be utilized for a wide range of application viz, irrigation, drinking etc. @ JASE
