MONITORING SYSTEM OF FISH POOL WATER TURBIDITY WITH ESP32 AND BLYNK
Technological developments in all aspects of life today are urgently needed, this can be seen from the many technologies that have replaced human jobs. As with the fish column at home, the work that is routinely done in the fish column is to replace the water in it if it is too cloudy so that it looks clean and creates good conditions for the development and health of the fish. Usually, fish farmers will make a schedule to check water quality and replace it. This work can sometimes take up time, especially when busyness increases and if you are late or forget to change the water in the pond, it can harm the condition of the fish in it. To help overcome this problem, equipment has been designed to monitor the turbidity level of the water that can be monitored from anywhere and at any time. This study aims to produce a tool that can monitor and control the condition of the level of water turbidity in fish ponds so that fish growth can be maximized. This monitoring is carried out regularly in real-time using IoT (Internet of Things) so that it can facilitate monitoring without the need to come directly to the pond location. This research succeeded in creating a monitoring system that can detect the turbidity of aquarium water using the ESP 32 tool and display on the Blynk application automatically in real-time
EVALUATION OF ANXIOLYTIC POTENTIAL OF VARIOUS EXTRACTS OF TAMARINDUS INDICA FLOWERS
Objective: The objective of this study was designed to gauge the antianxiety activity of varied extracts, namely, n-hexane, chloroform, ethyl acetate, and methanol of the flowers of Tamarindus indica using elevated plus maze (EPM) model in albino mice.
Methods: Coarsely powdered tamarind was powdered and subjected to exhaustive Soxhlet extraction using n-hexane, chloroform, ethyl acetate, and methanol. Solvents were recovered from all extracts using a rotary vacuum evaporator under reduced pressure. Albino mice have ministered orally with different doses of the extracts (i.e., 200 and 400 mg/kg) and behavior was observed on the EPM. The standard (positive control) employed in the study Diazepam (2 mg/kg, P.O).
Results: Results indicate that the methanol extract of T. indica flowers showed maximum and significant dose-dependent effect at 200 and 400 mg/kg on EPM, the results were just like the standard antianxiety agent diazepam (2 mg/kg). Locomotor activity evaluated with two different doses of T. indica (200 and 400 mg/kg) using actophotometer. The results were shown to be decreased in a dose dependent model compared to control.
Conclusion: The methanol extract shows that the presence of polyphenols could be liable for the anxiolytic potential of T. indica. Hence, this plant could also be used as a useful antianxiety agent
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
Discovery of Frequent Itemsets: Frequent Item Tree-Based Approach
Mining frequent patterns in large transactional databases is a highly researched area in the field of data mining. Existing frequent pattern discovering algorithms suffer from many problems regarding the high memory dependency when mining large amount of data, computational and I/O cost. Additionally, the recursive mining process to mine these structures is also too voracious in memory resources. In this paper, we describe a more efficient algorithm for mining complete frequent itemsets from transactional databases. The suggested algorithm is partially based on FP-tree hypothesis and extracts the frequent itemsets directly from the tree. Its memory requirement, which is independent from the number of processed transactions, is another benefit of the new method. We present performance comparisons for our algorithm against the Apriori algorithm and FP-growth

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)
Comparative study of hematological and blood chemistry of Indian and Italian Grey Mullet (Mugil cephalus Linneaus 1758)
Blood hematological and serum biochemistry parameters are often used to assess the health status and as stress indicators
in fishes. In the present study was undertaken to comparative study of hematological and blood chemistry of Indian and Italian Grey Mullet
(Mugil cephalus) to establish baseline values. Fifteen sexually immature and disease-free Indian wild fish (26.25 ± 0.23 cm total length,
347.55±14.27 g weight) and 15 Italian fish (31.53 ± 1.08 cm total length, 416.5 ± 14.56 g weight) were examined
Puducherry mangroves under sewage pollution threat need conservation
Indian mangroves have a rich diversity
of soil-dwelling organisms which include
micro, meio and macro forms. Mangrove
ecosystem provides an ideal nursery and
breeding ground for most of the marine
and brackish water fish and shellfish.
India has only 2.66% of the world’s mangroves1,
covering an estimated area of
4827 sq. km. The present study area lies
within the margins of lat. 11°90′107″–
11°90′703″N and long. 79°80′547″–
79°81′851″E. 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
