The impact of a plastic ban implementation scenario on residents of Tiruchirappalli region
No full textPlastic was created first for its durability, extended life, and capacity to be moulded into a broad range of items. There are three reasons why plastics are still used in the packaging sector, even though they are harmful to the environment. First, its low economic cost and widespread circulation. The second feature is their capacity to contain air and water while remaining watertight. The third characteristic is its relative inertness. Based on this, respondents were polled to assess their awareness of alternatives and to comprehend the pre- and post-ban situation for plastics. About 370 respondents from different age groups from different sectors from urban and rural dwellers of Trichy were asked about the prohibition of plastic carry bags, its acceptance, the alternatives available and the cost paid. Most respondents were unhappy about the removal of plastic bags and the high cost of cloth or other bags. Due to environmental concerns and their implications, it was revealed that the negative effects of plastics had not entered society sufficiently to allow the people to reject them. However, durability, lightness, flexibility, and low cost still predominate because the consumer requires plastic bags. Strict steps aiming at promoting public knowledge of the damaging consequences of plastics, their negative impact on the environment, and lowering the costs of alternatives should be explored as immediate remedies

No full textCircadian Rhythm of Ambient Noise Off the Southeast Coast of India
No full textAn ambient noise system consisting of a vertical linear hydrophone array was deployed in the shallow waters off Chennai, southeast coast of India from 1 August to 16 September 2013 to record ambient ocean noise of frequencies up to 10[Formula: see text]kHz. Biological sounds, which are broadband, short duration signals resulting from Terapon theraps, a native species, are a prominent feature of the ocean soundscape. Terapon activity peaks at 8[Formula: see text]pm and 11[Formula: see text]pm, and its presence is not observed after 12 midnight in both the months. In the other period, the ambient noise fluctuation is due to wind and vessel traffic. Hence, the present study focuses on the description of the ambient noise fluctuation over two 12[Formula: see text]h periods, i.e., 12 midnight–12 noon considered as period I, and 12 noon–12 midnight as period II in order to show the circadian rhythm of ambient noise. In this study area, Terapon vocalization reached 25[Formula: see text]dB above the ambient noise level and it dominates the short-term spectra records in the 0.4–4[Formula: see text]kHz range. All Terapon signals had daily patterns of sound production with highest levels of activity after dusk during the study period. The result shows that the circadian rhythm of ambient noise is mainly of biological sound generated by Terapon and it is reported first time in the shallow waters off the southeast coast of India.</jats:p
A DEMOGRAPHIC APPROACH FOR UNDERSTANDING THE INCIDENCE OF SICKLE CELL DISEASE PATTERN: A STUDY IN NILGIRI DISTRICT OF TAMIL NADU
No full textABSTRACT The goal of the study was to estimate of Sickle cell disease by age, gender and ethnicity. Age-specific rates are used for comparing age-defined subgroups when rates are strongly age-dependent for tribes in Nilgiris. Newly screened sickle cell patients in 1997 to 2012 were identified among the tribes of Nilgiri district and the data was received from NGO's in the district. Incidence rate pr 100,000 person-years were calculated using direct method of age standardisation. A total of 2867 newly diagnosed (incident) cases of sickle cell disease were identified, which gave the overall age and gender specific and adjusted incidence rate of 48.5. The incidence of SCD rapidly increased over the age group of 0-14 (25.8 %), 15-24 (19.7 %) 25-49 (44.1 %), but only 0.2 % of the cases being under the age of group of 75 above. The rate for men (44.5) was higher than female (27.8). The overall age adjusted rate for both gender per 100,000 was highest among Irula (24.4, 95% CI: 23.2, 25.5) followed by Kurumba (13.1, 95% CI: 12.2, 13.9), Pannaiya (9.9, 95% CI: 9.1, 10.6) and Kattunaikan (0.98, 95% CI: 0.6, 1.1). The present study demonstrates the age variations of Sickle cell disease incidence among tribes of Nilgiris. Aging study to estimate the Sickle cell disease incidence rate and to assess vulnerable age groups to determine the severity of disease for further studies. Through this study target programmes and screening facilities may be concentrated based on tribal groups and age influences

Waste in Flux: Temporal and Seasonal Shifts in Mysuru and Tiruchirappalli
No full textEfficient management of municipal solid waste is essential to fostering sustainable urban growth, especially in rapidly urbanizing countries such as India. This study conducts a comparative analysis of waste collection patterns in Mysuru and Tiruchirappalli, two major cities in India. The study specifically examines temporal shifts and seasonal variations. A study of daily waste collection data over six years indicates apparent differences among the cities. Mysuru has a greater average daily waste collection of 481.82 tons compared to Tiruchirappalli’s 445.68 tons. A two-sample t-test assuming unequal variances indicates that this difference is statistically significant with a p-value of 0.0423. However, a more thorough analysis of seasonal patterns uncovers significant deviations. Mysuru exhibits elevated waste generation during the dry summer and wet winter seasons, whereas Tiruchirappalli encounters a surge in waste generation during the wet summer and wet winter periods. The seasonal variations highlight the impact of climate-related factors and consumption habits on waste generation. This study offers valuable insights into the intricacies of urban waste management in India, highlighting the importance of customized strategies that consider both temporal and seasonal fluctuations to improve the sustainability and resilience of waste management systems in rapidly developing urban areas
