    In present investigation nesting and breeding of common coot (Fulica atra) from Ujani-Bhigwan reservoir, Maharashtra, India.  Total 56 nests were observed in study area, in which 31 eggs and 68 chicks were observed. Parameters such as depth of water, nest distance from river bank, shape of nest and nest material were assessed in this research. Nest construction, Parental care, and feeding to youngones are contributed by both of parents. The Typha angustifolia and Ipomoea carnea was main base for the nest construction of common coot (Fulica atra). Predator, over fishing, pollution, illegal sand mining, tourist activities and anthropogenic activity are threats identified to the nest of common coot (Fulica atra). It is an important primary data-base for this nesting site of Common coot with major details fist-time

    Synthesis and antimicrobial activity of some novel 2-azetidinones and 4-thiazolidinones derivatives

    Several 2-azetidinones 2a-e and 4-thiazolidinones 3a-e have been synthesized from halo-substituted Schiff bases using conventional as well as microwave technique. The newly synthesized compounds were established on the basis of spectroscopic technique. Further, all compounds screened for antimicrobial activity against Bacillus subtilis, Escherichia coli, Aspergillus niger and Aspergillus flavus. Most of the titled compounds show potent activity

    Sanjay Gandhi National Park (SGNP), surrounded by the megacity of Mumbai, India, is subject to high anthropogenic pressures. However, it constitutes an important ‘green lung’ and water source, supporting biodiversity, tourism, recreation and additional benefits both locally and remotely. To safeguard and enhance the Park ecosystem, there is a need to recognise and demonstrate the diversity of values associated with these multiple benefits, potential conflicts, and management measures necessary to protect them. This study explores outcomes from SGNP across a systemically connected range of ecosystem services, and the geographical scales over which service benefits accrue. This informs potential novel ‘payment for ecosystem services’ (PES) opportunities. The protected status of the landscape is reflected in low values from provisioning services (material or energy exploitation), but substantial values from supporting (such as habitat for wildlife), regulating (including global climate, microclimate and hydrological regulation) and cultural (particularly tourism) services. However, direct resource exploitation by communities inhabiting the Park is limited. Some ecosystem services were identified as ready for PES implementation (for example water supply), others require further development (including contributions to peripheral urban microclimate), through many services have no or limited PES potential (such as wood or aggregate extraction, prohibited under Park regulations)

    Environmentally benign, economically feasible, and solvent-free syntheses of series of imines by the condensation of a substituted hydroxynaphthyl ketone with several substituted iodoanilines under grinding approach are described. Imines were further tested for antioxidant activity; most of them show moderate activity. DOI: http://dx.doi.org/10.17807/orbital.v7i3.60

    Biologically Inspired Energy Efficient Routing Protocol in Disaster Situation

    Wireless sensor network (WSN) plays a crucial role in many industrial, commercial, and social applications. However, increasing the number of nodes in a WSN increases network complexity, making it harder to acquire all relevant data in a timely way. By assuming the end node as a base station, we devised an Artificial Ant Routing (AAR) method that overcomes such network difficulties and finds an ideal routing that gives an easy way to reach the destination node in our situation. The goal of our research is to establish WSN parameters that are based on the biologically inspired Ant Colony Optimization (ACO) method. The proposed AAR provides the alternating path in case of congestion and high traffic requirement. In the event of node failures in a wireless network, the same algorithm enhances the efficiency of the routing path and acts as a multipath data transmission approach. We simulated network factors including Packet Delivery Ratio (PDR), Throughput, and Energy Consumption to achieve this. The major objective is to extend the network lifespan while data is being transferred by avoiding crowded areas and conserving energy by using a small number of nodes. The result shows that AAR is having improved performance parameters as compared to LEACH, LEACH-C, and FCM-DS-ACO

    In this paper presents bending characteristic of multi-layered carbon nanotube reinforced functionally graded composite plates. The finite element implementation of bending analysis of laminated composite plate via well-established higher order shear deformation theory(HSDT). A seven degree of freedom and C0 continuity finite element model using nine noded isoperimetric elements is developed for precise computation of ply-by-ply deflection and stresses of laminated Single Wall Carbon Nanotube Reinforced composite plate subjected to uniform transverse loading. The finite element implementation is carried out through a finite element code developed in MATLAB.The results obtained by present approach are compared with results available in the literatures. The effective material properties of the laminated SWCNTRC plate are used by Mori-Tanaka method.Numerical results have been obtained with different parameters, width-to-thickness ratio(a/h), stress distribution profile along thickness direction,different SWCNTRC-FG plate, boundary condition and various lamination schemes

    A REVIEW OF DRISHTI

    Ayurveda is a wide and deep science which itself is full of knowledge and many scientific facts. With time these facts have been established by the great pioneers of Ayurveda. Their contributions for establishing various concepts create milestone in the history of Ayurveda. Innumerable researches and experiments are going on in the field of Ayurveda but some controversies are still remaining. Drishti is one of the controversial terminologies in Shalakya Tantra and there are many concepts which have been given time to time and are still evolving. At some places Drishti is taken as a functional entity and at other places as a structural unit. It also appears to have both structural and functional properties in few contexts. In the present study attempts are made to clarify the concepts regarding properties of Drishti on the basis of Ayurvedic texts and modern ophthalmology and conclusions have been drawn accordingly

    Craniofacial fibrous dysplasia: Report of a case using computed tomographic scan diagnosis

    No full text
    Fibro-osseous lesions are benign mesenchymal tumors in which mineralized tissue, blood vessels, and giant cells, in varying proportions, replace normal bone. Although this group of lesions includes reactive lesions, harmatomas, and neoplasms, they cannot be distinguished only on the basis of the histopathology which can only confirm their common fibro-osseous nature. Definitive diagnosis requires thorough radiological evaluation. Computed tomographic images of craniofacial fibrous dysplasia on bone windows may be helpful and allow precise pre-operative diagnosis and surgical planning
