Abstract

Two edible fishes, Bulls eye, Priacanthus hamrur (Percidae) and Hard tail scad, Megalaspis cordyla (Carangidae) from the waters of Royapuram coast, Chennai, Tamil Nadu were chosen for isolation of bacterial human pathogens in their gills, intestine, muscle and skin. Based on their growth characteristics on specific culture media, the following human bacterial pathogens, Escherichia coli, Salmonella typhi, Pseudomonas aeruginosa, Vibrio cholerae and Shigella dysenteriae were isolated in both the fishes. The medium of the fishes and the sediments of their habitat were furthermore collected and examined for pathogens. Different bacterial species were found in the medium that was analyzed, including the human pathogens isolated from the fishes. Surprisingly the five human bacterial pathogens harbored in the fishes were found in the medium but not in the sediment. This research is primarily to highlight the quality of these two edible fishes in the coastal waters of Royapuram, Chennai and to create awareness amid fish eating population.

Abstract

Nitrogen fertilizers tend to increase ammonium concentration especially in the aquatic medium. To evaluate its impact, the acute toxicity of ammonium sulphate, urea and a composite fertilizer (15:15:15) (NPK-1) was assessed in fingerlings of fresh water fish Catla catla using a static test system. The toxicity of ammonium sulphate, urea and NPK1 to C. catla increased with increasing fertilizer concentration and duration of exposure. The concentration that killed 10% (LC₁₀) and 90% (LC₉₀) of fish varied with the fertilizers. The concentrations of ammonium sulphate, urea and NPK- 1 that killed 50% of fingerlings of C. catla within 96-h (96-h LC₅₀) were 0.12, 0.19 and 0.18 g/L, respectively. Ammonium sulphate concentrations killing 50% (LC₅₀) of the fingerlings of fresh water fish Catla catlawere 0.23, 0.17, and 0.14, 0.12 g/L during 24hr, 48hr, 72hr and 96hr correspondingly. Ammonium sulphate was found to be more toxic to the juvenile fresh water fish C. catla compared to urea and NPK-1.

Abstract

The polyphagous devastating pest Spodoptera litura was infected in with the bioinsecticide Steinernema - Xenorhabdus symbiont and the larvae were used to analyse the protein content in both infected and control larvae. The EPN - Entomopathogenic nematodes were isolated from Westernghat region of Marudhamalai area and used in this study. The infected larvae after 24 hours were taken along with non infected control S. litura with three replication revealed that the infected had less protein content compared to control. This may be due to the utilization of the protein by the Steinernema - Xenorhabdus symbiont for their growth, development and reproduction.

Abstract

The present investigation focuses on the antimicrobial potential of leaf extract of Psidium guajava and its isolated fraction against the selected bacterial strains. Ethnolic leaf extract of Psidium guajava and its isolated fraction was more potent in inhibiting the growth of pathogenic Escherichia coli, Staphylococcus aureus and Staphylococcus epidermidis with different degree of inhibition. The antibacterial activity was more effect in isolated fraction compound than the plant extract. The results support the notion that plant extract containing compound may have many roles in pharmaceuticals as antimicrobial formulations.

Abstract

In vitro studies was conducted to evaluate the effect of seaweed extracts of Caulerpa racemosa (green alga), Sargassum myricocystum (brown alga) and Gracilaria edulis (red alga) against the mycelial growth of Macrophomina phaseolina at different concentrations of 10, 15, 20, 25 and 30 per cent along with control by poison food technique. The result revealed that extract of S. myricocystum showed significant antifungal activity against pathogen followed by G. edulis and C. racemosa. S. myricocystum (30%) extract recorded the lowest mycelial growth (45.2, 50.6, 58.4 and 61.5 mm) at 24, 48, 72 and 96 hrs after incubation. Among the antagonists tested against Macrophomina phaseolina, the fungal antagonists Trichoderma viride was found to be most effective in reducing the mycelial growth than the bacterial antagonist Pseudomonas fluorescens. Both the antagonistic of fungi and bacteria has compatability with seaweed extracts in all the concentrations.

Abstract

Soil information system in SOTER (soil and terrain digital database) framework is developed for the Indo- Gangetic Plains (IGP) and black soil regions (BSR) of India with the help of information from 842 georeferenced soil profiles including morphological, physical and chemical properties of soils in addition to the site characteristics and climatic information. The database has information from 82 climatic stations that can be linked with the other datasets. The information from this organized database can be easily retrieved for use and is compatible with the global database.

Abstract

In recent years, georeferenced soil information system has gained significance in agricultural land-use planning and monitoring the changes in soil properties/ soil quality induced by land-use changes. The spatiotemporal information on saturated hydraulic conductivity (sHC) and soil water retention-release behaviour is essential for proper crop and land-use planning. The sHC greatly influences the drainage process and soil water retention-release behaviour, ultimately affecting the crop growth and yield. However, sHC and water retention are not measured in a routine soil survey and are generally estimated from easily measurable soil parameters through pedotransfer functions (PTFs). In the present study, PTFs for sHC and water retention were developed separately for the soils of two food-growing zones of India (the Indo-Gangetic Plains (IGP) and the black soil region (BSR)). For the IGP soils, sHC is affected by the increased subsoil bulk density due to intensive cultivation. In BSR, presence of Na⁺ and Mg⁺⁺ ions affects the drainage and water retention of the soils. Therefore, these soil parameters were considered while developing the PTFs using stepwise regression technique in SPSS. The validation of PTFs was found to be satisfactory with low RMSE values and high model efficiency.

Abstract

Current status of land/soil resources of the Indo- Gangetic Plains (IGP) is analysed to highlight the issues that need to be tackled in near future for sustained agricultural productivity. There are intraregional variations in soil properties, cropping systems; status of land usage, groundwater utilization and irrigation development which vary across the subregions besides demographies. Framework for land use policy is suggested that includes acquisition of farm-level data, detailing capability of each unit to support a chosen land use, assess infrastructural support required to meet the projected challenges and finally develop skilled manpower to effectively monitor the dynamics of land use changes.

Abstract

This paper is mainly related to Data Mining and in particular it is in Clustering. Partitioning a large set of objects into homogeneous groups is a fundamental operation in Data Mining. This process of grouping objects into homogenous groups is called as clustering. In general, K-Means algorithm is used for clustering large data sets in Data Mining but its efficiency is limited to cluster numerical objects only. However, K-Means algorithm working efficiently with numerical values, its use is limited in Data Mining because data sets in Data Mining often contain categorical values. In this paper we present an algorithm called K-Modes algorithm to extend the K-Means paradigm to categorical domains. Here we introduce new dissimilarity measures to deal with categorical objects, replace means of clusters with modes and use a frequency based method to up date modes in the clustering process. Here the WEKA tool is used for the implementation of K-modes algorithm.

Abstract

The ectomycorrhizal fungi show higher tolerance to high soil temperatures, various soil and root borne pathogens and heavy metal toxicity. Hence an attempt has been made to investigate the growth characteristics of different ectomycorrhizal fungi on different carbon sources. The effect of different carbon sources viz., lactose, maltose, mannitol, and sucrose on the growth of Scleroderma citrinum, Suillus brevipes on day 30 and 45 were carried out. Scleroderma citrinum showed maximum growth on sucrose and lactose whereas Suillus brevipes showed maximum growth in lactose and mannitol in all the day intervals (30^th and 45^th days). On day 30 and 45 change in pH in the culture filtrate of Scleroderma citrinum and Suillus brevipes were also determined. The study revealed about the suitable carbon source for the mass cultivation of the selected ectomycorrhizal fungi.

Abstract

Objective of the Work: The highlight of this research work is to discover the ethylene gas level used for ripening of fruits by detecting ethylene gas (C2H4 in ppm) level employing soft sensor built using image processing and Artificial Neural Networks (ANN) algorithms. Methods/Statistical Analysis: The proposed method relies on the color which denotes the various stages in ripening and in turn indicates the amount of ethylene gas required. The changes in color, texture, intensity variation, mean, variance and standard deviation extracted from the images are the features which enable the personnel to determine the amount of ethylene gas. The Feed Forward Neural Network (FFNN) is used for ethylene gas estimation. This is made possible using Back Propagation Algorithm (BPA) for training the FFNN. As a part of image processing the intensity values in color images and its variation are tracked by dithering which is used as a unique feature input to train the FFNN. Major Findings: The novelty of the proposed method depends on the FFNN estimating the ethylene gas needed for ripening process in a feed forward fashion thereby providing the precision and recall values spontaneously for every instance. Application/Improvements: Earlier a circuit with capacitance model is used to generate ethylene gas for this purpose. Nearly 51 images are considered for training and testing respectively. Testing and confirmation result shows the required precision and recall level are in range of 80 to 89% and 100% respectively.

Abstract

Combustion quality in power station boilers plays an important role in minimizing the flue gas emissions. In the present work various intelligent schemes to infer the flue gas emissions by monitoring the flame colour at the furnace of the boiler are proposed here. Flame image monitoring involves capturing the flame video over a period of time with the measurement of various parameters like Carbon dioxide (CO2), excess oxygen (O2), Nitrogen dioxide (NOx), Sulphur dioxide (SOx) and Carbon monoxide (CO) emissions plus the flame temperature at the core of the fire ball, air/fuel ratio and the combustion quality. Higher the quality of combustion less will be the flue gases at the exhaust. The flame video was captured using an infrared camera. The flame video is then split up into the frames for further analysis. The video splitter is used for progressive extraction of the flame images from the video. The images of the flame are then pre-processed to reduce noise. The conventional classification and clustering techniques include the Euclidean distance classifier (L2 norm classifier). The intelligent classifier includes the Radial Basis Function Network (RBF), Back Propagation Algorithm (BPA) and parallel architecture with RBF and BPA (PRBFBPA). The results of the validation are supported with the above mentioned performance measures whose values are in the optimal range. The values of the temperatures, combustion quality, SOx, NOx, CO, CO2 concentrations, air and fuel supplied corresponding to the images were obtained thereby indicating the necessary control action taken to increase or decrease the air supply so as to ensure complete combustion. In this work, by continuously monitoring the flame images, combustion quality was inferred (complete/partial/incomplete combustion) and the air/fuel ratio can be automatically varied. Moreover in the existing set-up, measurements like NOx, CO and CO2 are inferred from the samples that are collected periodically or by using gas analyzers (expensive). The proposed algorithm can be integrated with the distributed control system (DCS) that is used for automation of the power plant. The inferred parameters can be displayed in the centralized control room a (cost-effective solution). The major contribution of this research work is to develop an indigenous online intelligent scheme for inferring the process parameters and gas emissions in the centralized control room directly from the combustion chamber of a boiler.

Abstract

It's a comprehensive fact that millions of people around the world surf the Internet for want of answers for their questions. Generally, the questions are asked in the form of Searching or direct questions which follow perfect ontological directions. It is important that the system understands the questions in the right sense and can provide the best answer for all the questions raised in the web forum. One such pragmatic method is required which is expected to provide optimum solution to achieve best answers for questions that not only percepts language but also follows perfect ontological information in accordance with the cyber law. This Proposed Model presents a new dynamic model called Knowledge Understanding and Advance Searching (KUAS) that studies the importance of Smart Question Answering with other question answering engines like START and proves to give the optimal solution compared to them.

Abstract

One third of India’s population is dependent on wood fuel for cooking their daily meals, which generates tremendous pressure on the scanty vegetation. Although we have modern technologies and fast developing industrial sector, gas and electricity are neither available nor affordable for this large section of the population. The predominant Zizyphus tree species can survive well in high temperature, slight frost and low rainfall. Their roots penetrate deeply in to ground water level and so they do not compete for water with the crop plants (Leaky and Last, 1980). Most of species are scattered widely throughout tropical and subtropical arid regions. Several of these are categorized as “multipurpose trees” and are backbone of rural economy throughout the drier plants of the world. It is because of the dependence on these species that plants have become over exploited. Tremendous pressure exerted by both man and animal, resulted in complete removal of superior germplasm or in some cases plant species have become threatened (Ramawat and Nadwani, 1991). The situation has become compounded by various inherent biological problems.

Abstract

Anaemia is the most common micro-nutrient deficiency disorder in the world. The prevalence of anaemia is higher in developing countries than in developed countries. Anaemia affects half a billion women of reproductive age worldwide. India had always been the country with the highest prevalence of anaemia and the home of the largest number of anaemic individuals in the world. A cross sectional community based study was conducted to estimate the prevalence of anaemia among 700 young women in the age group of 19-35 years hailing from different rural areas of Karamadai from Coimbatore district and to assess their iron nutriture. Data on anthropometric measurements, biochemical investigations and dietary details were recorded using a pre-designed, pre-tested proforma. Data were analyzed statistically using mean, standard deviation and ANOVA. Hemoglobin estimation (Cyanmet haemoglobin method) revealed that the prevalence of anaemia among rural women (N = 580) and it was reported that 84.83% of the rural young women were moderately anaemic and 14.83% were mild anaemic. A subsample of 85 moderate anaemic subjects were divided into Group 1 (Nutrition Education + Food supplement intervention), Group 2 (Nutrition Education+Kitchen garden intervention) and Group 3 (Nutrition Education intervention) and subjected to respective intervention for four months. Biochemical analysis revealed significant increase (p≤0.01) in haemoglobin level among the subjects in Group 1, Group 2 and Group 3 after intervention further showing that the majority of rural women improved from moderate to mild level of anaemia and from mild level to normal level of hemoglobin after intervention. Therefore the intervention measures are more effective when they are integrated with other approaches namely better nutritional practices, fortification, dietary modification, infection control, public health measures and income generation programmes. Nutrition education must be made an integral part to all the strategies.

Abstract

The present investigation was carried out during 2016-2017 to identify the seed development maturation studies in Barnyard millet cv. MDU 1. The results revealed that seeds attained physiological maturity on 50 days after anthesis as evidenced by the maximum panicle length (30.7 cm), fresh weight (31.2 g), dry weight (23.5g), fresh weight of the seeds (23.4g) and dry weight of the seeds (14.5g). The change of colour of panicle and seed from green to dark brown could be considered as a visible index of maturity. The seed quality parameters viz., germination (51 %), shoot length (9.59 cm), root length (18.5 cm) and dry matter (0.025 g/10 seedlings) and vigour index (1175) were also maximum at 50 days after anthesis.

Abstract

Objectives: To make a fully automated algorithm that is based on simple and quick steps, which produces consistent output for the same inputs. Methods/Statistical Analysis: For thorax and lung segmentation, region growing based method is used to segment the region of interest. The missing parts of the lungs are reconstructed using morphological operations. After that, nodules are detected based on the features of the reconstructed image. Artificial Neural Network has been used for classifying the images. Findings: An aggregate of 100 pictures with determination of 512 × 512 pixels with eight bits for every shading channel are caught. 90% affectability was obtained with 0.05 false positives for each picture. Application/Improvements: This framework distinguishes the phase of lung malignancy. The outcomes demonstrate that the tumors are of various measurements. By estimating the measurements of the tumor the lung disease stage can be recognized precisely utilizing the proposed technique. The outcomes indicate great potential for lung growth identification at beginning time.

Abstract

Objectives: To model a novel ceaseless client validation method to authorize the client regardless of their body position before the capturing system. The system ceaselessly validates the client with their various soft anthropometric parameters such as (e.g. wearables and skin) in addition to hard biometrics. Methods/Statistical Analysis: The proposed system mechanically stores in the soft anthropometric parameters each time the client logs in and integrate the anthropometric parametric features along with the conventional face traits for verification thus fusing the combination of hard and soft biometric attributes to attest a client ceaselessly. The methodology comprises of various modes such as initialization, validation and regeneration. Findings: Various samples of facial colour features and user’s cloth colour features are used as soft biometrics in this system for authorization. The experimental results of AR show the extensive improvement over the existing methods. Application/Improvements: This methodology eliminates the challenges faced in face recognition due to different expressions and postures, lighting effects. Thus the key discriminating features are authenticated using hard and soft biometrics thus making it a high secure technology.

Abstract

Natural forests and managed plantations constitute the largest land-use systems in the humid tropics of southwestern parts of Peninsular India comprising the Western Ghats and coastal plain. Soils therein are naturally acidic and the acidity is enhanced in managed land-use systems through inputs of chemical fertilizers. Plant nutrient deficiencies and mineral toxicities constrain crop production in acid soils. Surface soil and subsoil acidity in forest, coffee, rubber and coconut land-use systems was evaluated. The spatial pattern of surface soil and subsoil acidity pointed to low intensity of acidification in Malnad region of Karnataka, moderate acidity in northern Kerala and strong acidity in southern Kerala. Among the land-use systems studied, soils under natural forests and coffee plantations were only slightly acidic in surface soil and subsoil, whereas rubber- and coconut-growing soils were strongly acidic. Both natural and managed land-use systems, however, had strongly acid reaction in surface soil and subsoil in southern Kerala. Biomass production and crop yield are constrained in strongly acid soil by toxic levels of aluminium (Al) on soil exchange complex (>0.5 cmol (+) kg^–1 soil) and depletion of basic cations of calcium, magnesium and potassium (base saturation less than 50% or Al saturation more than 50%). Surface soil acidity can be ameliorated by incorporating liming materials into surface soils. In case of subsoil acidity gypsum too should be incorporated. Under humid climate partial solubility of gypsum permits movement of calcium into the subsoil layers, wherein calcium replaces the aluminium on exchange complex and sulphate radical precipitates the aluminium by formation of aluminium sulphate.

Abstract

In the present study Culex quinquefasciatus mosquito vectors were recorded in the study area distributed throughout Perumpallam canal, Erode District. Mosquito larvae were collected duringthe study period Jan – Dec 2018 in ten locations utilizing long larval nets in different sites of breeding. Temperature, pH and salinity were also measured seasonally in these sites. The survey revealed that the most common vector was Culex quinquefasciatus. Mosquito in Erode are prevalent in four seasons, rarely encountered in summer, moderation during the winter and are found in maximum during the post monsoon period.

Abstract

A species of torpedo electric ray, Torpedo polleni (Bleeker, 1865) has been reported for the first time from Indian waters. Six specimens of T. polleni measuring 147-397 mm TL were collected from shrimp trawl by-catches at Visakhapatnam, central eastern coast of India. The present paper provides description and comparison of morphometric data of T. polleni with closely resembling species of genus Torpedo thus helping in clearing taxonomic ambiguities. The present study suggests that T. polleni (Bleeker, 1865) with 6-8 knob-like papillae on the posterior margin of spiracle, the central papilla being larger, distance between eye and spiracle less than eye diameter, nasal curtain short and wide, its length more than half the length of inter narial width, first dorsal fin originating entirely above the pelvic fin base and base ending little beyond the pelvic fin, dorsal surface showing ornate appearance with close set of brownish-black spots, few spots very closely set or joined together forming vermiculations and dark brown lines is a valid species.
