Shear Strength Behaviour of Clay Reinforced with Treated Coir Fibres

The effect of treated coir fibres on the shear strength behaviour of clay is presented in this study. A series of consolidated undrained test were performed on soil reinforced with untreated, sodium hydroxide treated and carbon tetrachloride treated fibres. The coir fibre content was varied from 0.4% to 1.6%. The results indicated that the deviator stress at failure of the clay and clay with untreated coir fibres can be increased by treatment with carbon tetrachloride and sodium hydroxide. A significant increase was also observed in shear strength parameters of clay reinforced with coir fibres at different percentages. The two parameter dependent hyperbolic models were used for predicting the experimental results. The back predicted stressstrain curve at dierent fibre percentage was found to compare well with the experimental results. The clay reinforced with untreated/treated coir fibres has shown improved strength behaviour, it can be used for short term stability problems

Assessment of Possible Impacts of Climate Change in Water Reservoir of Bhopal with Special Reference to Heavy Metals, Central Region - India

Water is a unique substance. Its liquid face predominates on the Earth. Water of Kolar reservoir was investigated to assess its water quality status. Study reveals that physico \u2013 chemical characteristics of the reservoir water largely varied through change of season, degree of anthropogenic activities in and around ,the composition of runoff in the catchment area. Water samples were collected during winter and summer and analysed for various quality parameters with special reference to heavy metals e.g. Iron and Manganese. A perusual of chemical analysis revealed that Iron and Manganese content are more at station S4 which is a channel water outlet of dam

Status of hypertension control in urban slums of Central India: A community health worker-based two-year follow-up

Background: Hypertension (HTN) is a leading cause of cardiovascular diseases and its control is poor. There is heterogeneity in levels of blood pressure control among various population subgroups. The present study was conducted within the framework of the National Program for Prevention and Control of Cancer, Diabetes, Cardiovascular Diseases, and Stroke (NPCDCS) in India. It aims to estimate the proportion of optimal blood pressure control and identify factors associated with uncontrolled HTN consequent to initial screening. Materials and Methods: We assembled a cohort of individuals with HTN confirmed in a baseline screening in sixteen urban slum clusters of Bhopal (2017–2018). Sixteen accredited social health activists were trained from within these slums. Individuals with HTN were linked to primary care providers and followed up for the next two years. Obtaining optimal blood pressure control (defined as SBP <140 and DBP <90 mm of Hg) was a key outcome. Results: Of a total of 6174 individuals, 1571 (25.4%) had HTN, of which 813 were previously known and 758 were newly detected during the baseline survey. Two-year follow-up was completed for 1177 (74.9%). Blood pressure was optimally controlled in 301 (26%) at baseline and in 442 (38%) individuals at two years (an absolute increase of 12%; 95% CI 10.2–13.9). Older age, physical inactivity, higher body mass index, and newly diagnosed HTN were significantly associated with uncontrolled blood pressure. Conclusion: We found about six of every ten individuals with HTN were on treatment, and about four were optimally controlled. These findings provide a benchmark for NPCDCS, in terms of achievable goals within short periods of follow-up
