Ground Water Quality Assessment in Paper Mill Effluent Irrigated Area - Using Multivariate Statistical Analysis

Paper mill effluent while flowing, percolates through soil and slowly mixes with ground water bodies (Open well), water samples were collected from three stations (S1, S2 and S3) in and around paper mill. This paper represents the characteristics of ground water quality and the effect of paper mill effluent, which is using recycled water for irrigation and domestic purpose. Cluster analysis (CA), principal component analysis (PCA) and multidimensional scale plot (MDS) appear were employed to evaluate the tropic status of water quality for three monitoring stations. High pollution load was observed in the ground water bodies due to continuous flow of effluent near the ground water sources. Effluent water consists of 3400 mg/l suspended solids. However, pH varied from 5.5-7.6. The biochemical oxygen demand and chemical oxygen demand ranged from 2-780 and 60 - 1520 mg/l respectively. SAR, RSC and SSP level was high from S2 and S3, both were unsuitable for both domestic and irrigation purposes. An elevated coliform bacterial count indicates that these water samples S2 and S3 were not suitable for domestic purpose. The dendrogram of the effluent water quality parameters evidently indicate that Maruthi Paper mill does not meet nominal National standard set by central pollution control board to discharge in agricultural fiel

Haematology and biochemical parameters of different feeding behaviour of teleost fishes from Vellar estuary, India

Haematological parameters have been recognized as valuable tools for monitoring fish health. Haematological and serum biochemical parameters were studied and compared different feeding behaviour of teleost fishes. Three marine teleost fishes, Lates calcarifer (carnivores), Mugil cephalus (omnivores) and Chanos chanos (herbivores), were carried out in order to find out a normal range of blood parameters which would serve as baseline data for assessment of the health status of the fish as well as reference point for future comparative surveys. Blood parameters such as red blood cell count (RBC) and white blood cells count (WBC), haemoglobin, haematocrit, mean cell haemoglobin concentration (MCHC), mean cell volume (MCV), mean cell haemoglobin, glucose, protein, cholesterol and urea were estimated from teleost fishes of different trophic level. Statistical analysis revealed that differences in haematological parameters between marine fish were significant (P<0.01)

Mangrove exists as fringing vegetation over 168 ha distributed along the sides of Ariankuppam estuary, which empties into the Bay of Bengal (Coromandal coast) at Veerampatinam on the southeastern coast of Indi

Gender Based Mood Analysis on Purchase of Wrist Watches in Bangalore, Karnataka

Buying behavior and spending pattern are highly influenced by mood of the customer in general. Mood shapes person’s attention, choices of the product and purchasing decision though the life span of mood is short. Organizations must find out means and measures to trigger customers’ mood into positive that in turn will induce them to buy the product. This article focuses on gender-based mood analysis on purchase of wrist watches. The researcher has adopted structured questionnaire to get the primary responses from the respondent to study how far mood varies among the genders on purchase of wrist watches and researcher has made framework to highlight the order of the measures / attributes to be followed to trigger the customers’ mood. The researcher has applied descriptive statistics to present the key aspects of mood of the respondents and applied ranking method to identify the attribute that trigger the mood of the potential customers. It is concluded that the attribute of demonstration of wrist watches features in specific to men and women, building a community group and attribute of need, elite and self-esteem, sense of accomplishment, aspiration, and marketing communication tactics are some of the significant attributes that trigger the customers to buy wrist watches from highest order to lowest order

Structural and Electrical Studies of Boric Acid Doped Cadmium Oxide Thin Film by JNSP Technique for Optoelectronic Applications

The present work deals with preparation and characterization of boric acid (b) dopped cdo thin films by the jet nebulizer spray pyrolysis technique at optimized temperature 450°C. Boric acid doped cdo thin films were prepared by jet nebulizer spray pyrolysis technique with different wt% of boric acid (x=0, 0.5,2.5, 4). The xrd pattern of various weight percentage boric acid dopped cdo thin films show the polycrystalline nature with cubic structure. At room temperature, the electrical conductivity of the prepared films increases with 4Wt% of 2.32x10-3 S/cm. The plot of voltage versus current as a function of temperature (RT-30°C) indicates the ohmic behavior of the films. Moreover, significant optoelectronic applications are cadmium oxide dopped with boric acid thin films at room temperature electrical resistivity is in the order of 101Ω cm which is low enough to be a good supercapacitor electrode material

Human milk banking: One year experience from a tertiary care centre

Introduction: A human milk bank (HMB) systematically collects, screens, processes, and dispenses excess milk donated by healthy nursing mothers. First HMB of Asia was established in the year 1989 in Mumbai, but there are still insufficient milk banks in India. Objective: This study aimed to provide our experience in the past 1 year. Methods: This retrospective descriptive study was conducted in the HMB of a tertiary care institution. The data were collected from donor forms and other milk bank records in the milk bank. All the demographic details and bacteriological data were collected. Results: There were 1168 donors with no extramural donors. Of these, 882 donors had term babies and 286 had preterm babies. The mean age of the donor population was 23.53±3.27 years. On the analysis of the volume of milk donated, the mean volume was 77.62±51.26 ml. A total of 90,660 ml of human milk was collected during the study period of 1 year. The bacteriological culture of the donor milk showed growth in 42 (3.6%) samples and was discarded. Klebsiella (2.39%) was the most common organism followed by Escherichia coli (0.44%) and Staphylococcus (0.35%). There were 1424 recipients and about 74% of them, were preterm babies. There were no extramural recipients. Conclusion: For a large number of preterm babies and the neonates without breast milk in India, pasteurized donor human milk will be the best source of nutrition. Hence, number of HMBs will improve the neonatal survival and reduce the morbidity

Did mangroves offer an effective barrier to the Thane cyclone surges?

Mangrove ecosystems support vital wetland communities of plants and animals. They are characterized by unique species of trees and shrubs that fringe the intertidal zone along sheltered coastal, estuarine and riverine areas in tropical and subtropical latitudes. Mangroves have played an important role in the economy of our coastal population for thousands of years, providing a variety of goods and services, including wood production, support for commercial and subsistence fisheries, aquaculture, salt production, and coastal erosion control

Effect of aqueous extract of horse purslane (Trianthema portulacastrum L.) on germination and seedling growth of selected field crops

An experiment was conducted during 2021 and 2022 in Anbil Dharmalingam Agricultural College and Research Institute, TNAU, Tiruchirappalli, to know the overall allelopathic impact of horse purslane on the germination and seedling growth of rice, ragi, maize, green gram and sunflower. A Completely Randomised Design (CRD) was used to test 6 treatments, including a control and 1%, 2%, 3%, 4% and 5% concentrations of horse purslane whole-plant extract, with 4 replications. Seed germination and subsequent growth and development of selected crops were negatively affected by the extract of horse purslane. The minimum germination was recorded in 5% horse purslane extract, while maximum germination was recorded in control. A consistent decline in germination percentage was observed with increasing extract concentrations. The extract of horse purslane significantly reduced the root length, shoot length, seedling length and seedling vigour index (SVI) of the tested crops. The highest seedling mortality rates were observed at the 5% extract concentration, with values of 83.8%, 78.9%, 47.3%, 51.6% and 81.3% for rice, ragi, maize, sunflower and green gram respectively. The study indicates that horse purslane needs to be controlled effectively in the cropped fields, otherwise, it could reduce the growth and development of field crops. The allelochemicals in horse purslane present significant opportunities for further research on their impact on other weed species, which could contribute to the development of effective weed management strategies in field crops
