Hydrological Analysis for Urban Water Management

Urban Water Management is the practice of managing freshwater, wastewater, and storm water as components of a basin-wide management plan. It builds on existing water supply and sanitation considerations within an urban settlement by incorporating urban water management within the scope of the entire river basin. The pervasive problems generated by urban development have prompted, in the present work, to study the spatial extent of urbanization in Golden Triangle of Odisha connecting the cities Bhubaneswar (20.2700° N, 85.8400° E), Puri (19.8106° N, 85.8314° E) and Konark (19.9000° N, 86.1200° E)., and patterns of periodic changes in urban development (systematic/random) in order to develop future plans for (i) urbanization promotion areas, and (ii) urbanization control areas. Remote Sensing, using USGS (U.S. Geological Survey) Landsat8 maps, supervised classification of the Urban Sprawl has been done for during 1980 - 2014, specifically after 2000. This Work presents the following: (i) Time series analysis of Hydrological data (ground water and rainfall), (ii) Buffer Analysis and other soft computing techniques for Urban Water Management, and (iii) Uncertainty analysis of model parameters (Urban Sprawl and correlation analysis). The outcome of the study shows drastic growth results in urbanization and depletion of ground water levels in the area that has been discussed briefly. Other relative outcomes like declining trend of rainfall and rise of sand mining in local vicinity has been also discussed. Research on this kind of work will (i) improve water supply and consumption efficiency (ii) Upgrade drinking water quality and wastewater treatment (iii) Increase economic efficiency of services to sustain operations and investments for water, wastewater, and storm water management, and (iv) engage communities to reflect their needs and knowledge for water management

Characterization of Malignant Melanoma Using Vibrational Spectroscopy

Malignant melanoma, a malignant neoplasm of epidermal melanocytes is the third most common skin cancer. In many cases, melanoma develops from nevus, which is considered as the nonmalignant stage. Fourier transform infrared microspectroscopy (FTIR-MSP), which is based on characteristic molecular vibrational spectra of cells, was used to investigate spectral differences between melanoma, nevus, and the corresponding normal epidermis. In the present work, FTIR-MSP was performed on formalin-fixed biopsies of melanoma and nevi along with the adjoining histologically normal epidermis to understand the biochemical variations from the epidermis and identify suitable parameters for differentiation of nevi from melanoma. The comparative analysis of various parameters calculated from the spectral data of the normal epidermis and the abnormal regions showed that the changes in the nucleic acids was a significant indicator of the abnormal nature of the tissues. The RNA/DNA ratio was decreased in case of both melanoma and nevus compared to the epidermis. The amide II/amide I ratio was greater for nevus and melanoma compared to the epidermis. In contrast to other organs, the analysis of carbohydrates was not found as a suitable indicator in case of malignant melanoma. Shifts in band wave number were found to be a major distinguishing feature between the melanoma and compound nevi. The present study helps in the identification of spectral features suitable for distinction of melanoma from nevus that appear similar even in FTIR spectral features and thus can pave the way for development of in vivo screening systems based on these diagnostic markers

Production of He-4 and (4) in Pb-Pb collisions at root(NN)-N-S=2.76 TeV at the LHC

Results on the production of He-4 and (4) nuclei in Pb-Pb collisions at root(NN)-N-S = 2.76 TeV in the rapidity range vertical bar y vertical bar <1, using the ALICE detector, are presented in this paper. The rapidity densities corresponding to 0-10% central events are found to be dN/dy4(He) = (0.8 +/- 0.4 (stat) +/- 0.3 (syst)) x 10(-6) and dN/dy4 = (1.1 +/- 0.4 (stat) +/- 0.2 (syst)) x 10(-6), respectively. This is in agreement with the statistical thermal model expectation assuming the same chemical freeze-out temperature (T-chem = 156 MeV) as for light hadrons. The measured ratio of (4)/He-4 is 1.4 +/- 0.8 (stat) +/- 0.5 (syst). (C) 2018 Published by Elsevier B.V.Peer reviewe

Mechanism of prevention of aggregation of proteins: a case study of aggregation of α-globulin in glycerol

The precipitation of proteins due to the changes in pH has been a major limiting factor in their utility especially when the precipitation is concurrent with irreversible aggregation. In the present study, an attempt is made to see the effect of glycerol on the pH-induced aggregation of &#945;-globulin which is the major protein fraction (11S) from Sesame (Sesamum indicum L.) seeds. A second order polynomial relation existed between the cosolvent concentration and precipitation which was prevented in presence of the cosolvent. Similarly, there was a second order polynomial relation between 8-anilino 1-naphthalene sulfonic acid (ANS) binding of the protein (as indicated by fluorescence emission at 466 nm) and the cosolvent concentration. The relative precipitation in presence of glycerol is however linearly proportional to the changes in surface hydrophobicity as seen by behavior of ANS with the protein in presence of the cosolvent. A possible role of the cosolvents in prevention of aggregation due to hydrophobicity of the protein is envisaged and the relation between the different parameters is discussed

Recalcitrant desmoid tumor of the abdominal wall: A reconstructive dilemma

Desmoid tumors are slow-growing benign tumors. These tumors infiltrate surrounding tissues but not malignant and associated with women of fertile age, especially during and after pregnancy. We report a young male patient with a recurrent desmoid tumor of the anterior abdominal wall who underwent resection four times earlier. The patient had a history of four-time operation over the same site for the same disease. Preoperative evaluation included thorough clinical examination with abdominal ultrasound. The histology revealed a desmoid tumor. Primary surgical resection and immediate reconstruction of abdominal defect were performed

Donor Finger Morbidity in Cross-Finger Flap: A Systematic Review and Meta-Analysis

Background The morbidity of donor finger in a cross-finger flap has not received as much importance as the outcomes of the flap itself. The sensory, functional, and aesthetic morbidity of donor fingers, reported by various authors, are often contradictory to each other. In this study, objective parameters for the sensory recovery, stiffness, cold intolerance, cosmetic outcome, and other complications in the donor fingers, reported in the previous studies, are systematically evaluated. Methods This systematic review is reported using Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) protocol and was registered with the International prospective register of systematic reviews (PROSPERO registration no. CRD42020213721). Literature search was done using “cross-finger,” “heterodigital,” “donor finger,” and “transdigital” words. Data regarding demography, patients' number and age, follow-up duration and outcomes of donor finger, including 2-point discrimination, range of motion (ROM), cold intolerance, questionnaires, etc. were extracted from included studies. Meta-analysis was performed using MetaXL and risk of bias was evaluated using Cochrane risk of bias tool. Results Out of the total 16 included studies, 279 patients were objectively evaluated for donor finger morbidity. Middle finger was most frequently used as donor. Static two-point discrimination seemed to be impaired in donor finger in comparison to contralateral finger. Meta-analysis of ROM suggested that statistically there is no significant difference in ROM of interphalangeal joints in donor and control fingers (pooled weighted mean difference: −12.10; 95% confidence interval: −28.59, 4.39; I2 = 81%, n = 6 studies). One-third of donor fingers had cold intolerance. Conclusion There is no significant effect on ROM of donor finger. However, the impairment that seems to be in sensory recovery and aesthetic outcomes needs to be further evaluated objectively
