A Preliminary Study on Microplastic Occurrences in Surface Waters of Ousudu Lake, Pondicherry, India.
Microplastics (MP) in both freshwater and marine ecosystem is the next issue that has been recently the fore. However, freshwaters are the potential source and pathway to transport MPs to the marine environment. There is a lack of understanding about the presence and analysis of MP in the freshwater system in India, one of the leading global plastic producers and consumers responsible for 5.6 million tonnes of waste every year. The present attempt is the first in Ousudu Lake, Puducherry, Tamil Nadu, to study the MPs occurrence and examine its properties in the surface water of the largest lake and an important wetland. The concentration range of MP in Ousudu Lake was 0.0039 particles/m2. Fibre was dominant, homogenous with the size fraction of ≤100µm comprised of total MPs collected in Lake. Raman spectroscopy identified plastics with polyethylene as a homogenous component. This study indicated that the presence of MP in water might influence the environment

As well as the field of agriculture is also developing in mobile application. In order to help the farmers in need of help, we have researched some information about mobile application and created an app based on soil analysis. Soil analysis is a major Problem of agriculture & farming, but their rapid identification remains difficult in many parts of the world due to the lack of the necessary infrastructure. The combination of increasing global smartphone penetration and recent advances in computer vision made possible by deep learning has paved the way for smartphone-assisted soil analyzing, Overall, the approach of training deep learning models on increasingly large and publicly available image datasets presents a clear path toward smartphone-assisted soil analyzing on a massive global scale
AUTOMATIC AIR PURIFIER
Air pollution is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles. OZONE, a gas, is a major part of air pollution in cities. When ozone forms air pollution, it's also called smog. If the air quality index (AQI) reports are anything to go by, then the quality of air in most cities of India is deteriorating day by day. As the winter months of October and November approach, the air quality outdoors becomes worse since the pollution that is generated from various sources gets trapped because of differences in air pressure, moisture and wind speeds. This also tends to have a direct influence on the indoor air quality in home or office spaces here most individuals tend to spend approximately 90% of their time. In the past decade or so, the home air purifier market has shifted multiple gears as an affordable solution for indoor air quality. Besides this, there have been seemingly ground breaking advancements in filtration technologies ensuring the development of the next level in air purifier
Zoning and mapping of landslide hazard in the Nilgiris district, Tamil Nadu, India
Landslide is the frequent disastrous events in the Nilgiris District. It shows a historical record in the study
area. The objective of this present study is to prepare a landslide hazard zonation map. The present study has
been carried out by using secondary sources of data. Total of 33 landslides has been recognized through
Landsat-8 satellite imagery. In this study, five parameters have been taken such as land-use/ land cover, rainfall,
slope, aspect and geology. The hazard zonation map has been done with the technique of Weighted Overlay
Analysis by using GIS software ARC GIS 10.4. The results of this study reveal that most of the landslide has
occurred in the east and center part of Nilgiris district which are highly prone to landslides. These regions are
in very high and high zones. The northern most part of the Nilgiris is in the low zone due to dense forest
covered. There are only 0.21 percentage of area is in under very high zone, 1.82 percentage is under the high
zone, 41.72 percentage is under the moderate zone,50.38 percentage is under the low zone and 5.91
percentage is under very low zone out of the total study area. Therefore, the results of this study also reveal
that the final map of hazard zonation can be useful for mitigating the hazard and is very helpful to planners and
engineers for determining the safe and suitable locations to continue the developmental works
Improving Power Quality Of Distribution Grid Using An Ultracapacitor Integrated With Power Conditioner
Entrance of different sorts of disseminated vitality assets (DERs) like sun oriented, wind, and module half and half electric vehicles (PHEVs) onto the dispersion lattice is on the ascent. There is a comparing increment in power quality issues and discontinuities on the circulation lattice. With a specific end goal to diminish the discontinuities and enhance the power nature of the conveyance framework, a ultracapacitor (UCAP) incorporated power conditioner is proposed in this paper. UCAP incorporation gives the power conditioner dynamic power capacity, which is valuable in handling the lattice irregularities and in enhancing the voltage hang and swell pay. UCAPs have low vitality thickness, high-control thickness, and quick charge/release rates, which are all perfect qualities for meeting high-control low-vitality occasions like sags/swells. In this paper, UCAP is coordinated into dc-connection of the power conditioner through a bidirectional dc–dc converter that aides in giving a hardened dc-interface voltage. The reconciliation helps in giving dynamic/responsive power bolster, irregularity smoothing, and list/swell pay. The aggregate consonant bending was lessened by utilizing fuzzy controller. Plan and control of both the dc–ac inverters and the dc–dc converter are talked about. The reproduction performed in MATLAB/SIMULINK condition
Correlation between body weight and postural control in healthy individuals using sway meter
BACKGROUND: Postural control is critical for ensuring a safety activity of daily living. Individuals with poor stability are more prone to fall while doing activities of daily living. A certain level of sway is essentially present due to small perturbation within the body during shifting body weight from one to other foot, breathing, etc. The purpose of this study was to analyze the correlation between body mass and postural control in normal, lean and obese individual. AIMS: to analyze the correlation between body mass and postural control in healthy individuals using sway meter. MATERIALS AND METHODS: This is an observational study done with 75 participants. Both male and female healthy individuals between 18-23 years were included in this study. Individuals with any musculoskeletal injuries, neurological conditions, peripheral artery disease and pregnant women were excluded from the study. BMI of each participant was calculated and assigned into three groups. Group A-lean, group B-normal and group C-obese. Postural control was analyzed for each group by using sway meter; level of postural sway was compared between groups A, B & C. RESULTS: On comparing mean values of groups A, B and C there was a positive association and strong correlation between body mass index and postural control with eye open and eye closed in anterior, posterior and postural sway towards left between the groups at (P ≤ 0.05). However, there was a negative association and weak correlation between BMI and postural control with eye open & eye closed in postural sway towards right between the groups at (P ≥ 0.05). CONCLUSIONS: This study reveals that there is strong correlation between BMI and postural control. Subjects in eyes closed and eyes opened conditions showed sway in anterior, posterior and left directions but there was less sway towards right side direction

Anakkavur. Study area is bounded by the Kancheepuram and Arakkonam Taluk in the North and Utthiramerur
Taluk in the East and Arcot Taluk in the West and Vandavasi Taluk in the South. The study area total population
is 380,367 as per 2011 census. Cheyyar Taluk lies between 120 52’55’’N to 120 32’52”N Latitude and 790
19’02’’E to 790 44’42’’E longitudes. The area constitutes a part of Toposheet Nos. 57P/6, 9, 10, 13 and 57P/14
published by Survey of India. The chief irrigation sources in the area are the tanks, and dugwells and tube wells.
The study area is studded with numerous surface water storage tanks of medium and minor types. Rural
population is mainly engaged in agriculture in the surveyed area. Paddy and Sugarcane is the major food crop in
the area and it is extensively cultivated (two crops) in entire Taluk. The drainage pattern is generally dendritic.
All the rivers are seasonal and carry substantial flows during monsoon period. The study area includes part of
Palar and Cheyyar river basin. The study area depends on surface and rainwater for domestic and irrigation
purposes. The geology of the area constituted by Charnockites of Archeaen age, Epidote- hornblende Gneiss
and Hornblende-Biotite Gneiss with Sand, silt ang Graval of sedimentary rocks. The predominant
Geomorphologic feature in the study area is pediments, shallow pediments, flood plains, buried pediments,
Sedimentary low land, Denudation hills and river basin. Around 25 representative ground water samples were
collected and they are physico-chemically analysed. The pH of the groundwater is Basic to Acidic in nature. With
reference to TH, the majority of the groundwater sample locations in Cheyyar Taluk are very hard water with
little hard to moderately hard water. In comparison with Bureau of Indian Standard (BIS, 1983) for drinking
water the majority of the ground water samples in the study area falls above the maximum permissible limit on
the basis of TDS and TH. Thus the effect of groundwater on the health of livestock’s and human population are
discussed in detail for the various ground water chemical parameters
