Two novelties in the genus Trias Lindl. (Orchidaceae)
No full textOne new orchid, Trias bonaccordensis Sathish, is described from the Bonaccord forests of Trivandrum, Kerala State, India. Affinities with the related T. stocksii Benth. ex Hook, f., T. disciflora (Rolfe) Rolfe and T. nasuta (Reichb. f.) Stapf are discussed. One new combination, viz. T. crassifolia (Thw. ex Trimen) Sathish, is proposed for the Sri Lankan Bulbophyllum crassifolium. Operculum features of the genus are illustrated and a distribution map is supplied

How do we evaluate risk?
No full text2019 Wall Scholar Sathish Gopalakrishnan, an Associate Professor at UBC's Electrical & Computer Engineering Department, has been exploring how individuals and societies understand risk in cyber-physical systems – artificial intelligence, robotics and their application in the world around us. That understanding can help us shape regulation and safety standards in an era of increasing automation.Applied Science, Faculty ofElectrical and Computer Engineering, Department ofUnreviewedFacult
Dynamics of coastal aquifers. Conceptualization and steady-state calibration of multilayer aquifer system-Southern coast of Emilia Romagna
Full text linkWorldwide, coastal aquifers have been heavily exploited by socio economic activities for several decades, and climate change and sea level rise have also been threatening coastal aquifers. The authorities and policymakers have been advised to find the solutions in order to achieve sustainable water resources management. The southern part of Po delta, Italy is a low-lying coastal area also experiencing tectonic activity. Along with low-lying topography, unstable shore line and sea level, the groundwater is heavily exploited by this deltaic multilayered system of aquifers. Hence, a multilayer three-dimensional model of this aquifer system has allowed for the investigation of the response of aquifer to natural and anthropogenic exploitation. The present work regards the conceptualization of the multilayer aquifer system using lithological cross-sections, surface water features, and appropriate boundary conditions and the steady-state flow modelling. The spatially distributed elevations of the groundwater table and piezometric head from the different aquifers have been calibrated. The values of model error statistics at a satisfactory range, such as R-squared, mean error, root-mean-squared error and model efficiency, confirm that the developed model is reliable, and calibration is obtained with good match between observed and simulated data. The developed model can be used as a decision-making tool for the authorities and policymakers in order to plan for sustainable water management
Impact of sea level rise and tidal effects on flux-controlled and partially isolated shallow aquifer on the southeast coast of India
No full textA rise in sea level is the most important threat to the coastal aquifers in which the intensity of threat also depends on the local hydrogeological settings. The present study seeks to identify the impacts of sea level rise and tidal effects on the shallow and complex aquifer located south of Chennai, India. The aquifer geometry is isolated dune surfaces due to the presence of enclosing saline surface water. The freshwater is available as an elongated lens, and replenishment occurs by rainfall, with limited regional influx. Numerical simulation was carried out to understand the response of groundwater table to sea level rise until the year 2100. Initially, the tidal effects were investigated for the duration of 3 years. A sinusoidal fluctuation of groundwater table is noticed only in the northern part and the tidal impact seems infinitesimal because of steep hydraulic gradient in the south. Simulation of groundwater table without considering sea level rise predicts a decline in the elevation of groundwater table/freshwater lens by − 0.35 m in the dune surfaces. The simulation with reported sea level rise of 2 mm year −1 with the same rate of groundwater pumping results in a total increase of 0.5 m in groundwater table. The study infers that the tidal effects are high in the shallow groundwater gradient, and sea level rise will be beneficial to the isolated coastal freshwater aquifers by increasing the elevation of groundwater table/freshwater lens and further deepening the interface between seawater and freshwater
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
