Potentiality of Kolar Dam Water for Drinking Purposes

Kolar Dam, a major masonry dam, is located about 35 km away from Bhopal, near Lawakhari village in Sehore District. Constructed across the Kolar River, a tributary of Narmada on the right bank, the dam is about 45 m high. The maximum storage capacity is 270 Mcm. Kolar reservoir is the important sources of potable water supply for the Bhopal city. To assess its suitability for drinking purpose, the physico chemical and microbiological characteristics were studied on monthly basis.  In general almost all the parameters are within the range except coliform bacteria. Coliform bacteria were found beyond the norm prescribed for drinking water by various agencies. The analysis indicates that the water of Kolar reservoir is moderately soft with moderate alkalinity, transparent, low BOD, COD level as apparent by the study. The overall water quality of Kolar reservoir is not much affected by anthropogenic sources as it is surrounded by thick forest and less human activities are evident in this area. Therefore its water can only be used for drinking purposes but only after conventional treatment and disinfection. Keywords: Kolar Dam, Water quality, Physico chemical parameter, Drinking water

Plants and age-structured pest dynamics with natural enemy as control strategy: A fractional differential equations model

In recent years, plant pests have drawn much attention from researchers. Biological control proved an efficient replacement for chemical and other pest control techniques. The present study proposes the cognition of an immature pest population unaffected by the natural enemy and grows exponentially by the harvesting effort of the mature pest population to plants. The fractional calculus environment proposes A four-compartment: plant, immature and mature pest, and natural enemy model. Equilibrium points and the system’s stability are studied theoretically and numerically. Simulation study for different values of fractional order generates the optimum solution. The suggested method is much more benignant than the existing method of ordinary differential equations as we can figure out the infrequent changes in the variable using a fractional derivative. Creating the memory effect in the system using fractional derivatives makes it more realistic

Notes for genera – Ascomycota

Knowledge of the relationships and thus the classification of fungi, has developed rapidly with increasingly widespread use of molecular techniques, over the past 10--15 years, and continues to accelerate. Several genera have been found to be polyphyletic, and their generic concepts have subsequently been emended. New names have thus been introduced for species which are phylogenetically distinct from the type species of particular genera. The ending of the separate naming of morphs of the same species in 2011, has also caused changes in fungal generic names. In order to facilitate access to all important changes, it was desirable to compile these in a single document. The present article provides a list of generic names of Ascomycota (approximately 6500 accepted names published to the end of 2016), including those which are lichen-forming. Notes and summaries of the changes since the last edition of `Ainsworth Bisby's Dictionary of the Fungi' in 2008 are provided. The notes include the number of accepted species, classification, type species (with location of the type material), culture availability, life-styles, distribution, and selected publications that have appeared since 2008. This work is intended to provide the foundation for updating the ascomycete component of the ``Without prejudice list of generic names of Fungi'' published in 2013, which will be developed into a list of protected generic names. This will be subjected to the XIXth International Botanical Congress in Shenzhen in July 2017 agreeing to a modification in the rules relating to protected lists, and scrutiny by procedures determined by the Nomenclature Committee for Fungi (NCF). The previously invalidly published generic names Barriopsis, Collophora (as Collophorina), Cryomyces, Dematiopleospora, Heterospora (as Heterosporicola), Lithophila, Palmomyces (as Palmaria) and Saxomyces are validated, as are two previously invalid family names, Bartaliniaceae and Wiesneriomycetaceae. Four species of Lalaria, which were invalidly published are transferred to Taphrina and validated as new combinations. Catenomycopsis Tibell Constant. is reduced under Chaenothecopsis Vain., while Dichomera Cooke is reduced under Botryosphaeria Ces. De Not. (Art. 59)
