This article sets out to know the opinions of poets, scholars, and sages in classical literature such as Ettuththokai (Eight Anthologies), Pathuppattu (The Ten Idylls), Pathinenkilkanakku (18 books), Didactic books, and Moral literature. And also, to explore the power of unadulterated honesty, truth, and dignity in friendship. Moreover, Kapilar was a great poet who was the chief scholar of the Tamil Sangam in education, questions, and in Madurai, the city where Tamil was developed with the various periods of Sangam as First Sangam, Middle (Idai) Sangam, and Last (Kadai) Sangam. Most of the songs in Sangam literature are sung by Kapilar.It has been thoroughly researched about the excellence of the friendship between the poet Kapilar and Velpari, the leader of the Velirkulam who ruled the small land of Parambu Nadu within the boundaries of the Pandya Empire, the grammar of friendship, the necessity of friendship, and friendship, as well as the unethical friendship that has been dealt with in Purananuru, Patirupattu, Siruppanaartuppai, Thirukkural, and Naladiyar. In the classical literature, the way in which Velpari and Kapilar valued friendship more than life, and the high spirit of Kapilar who stood as a close supporter of Velpari and guided Pari to defeat the enemy and helped him to achieve victory in the time of great suffering, is also explored in this article. Knowing that Pari cannot be defeated in a face-to-face fight, Moovendars (Three Great Kings) kills Pari by stratagem. After Velpari's death, Kabila, who had intended to sacrifice himself, changed his mind, thinking that if he too died, both of Pari's daughters would be left in a state of destitution. Kapila intended to get Pari's daughters married and appealed to the chieftains, Ilavachiko and Irungo, to share the fame of Pari and marry his daughters. Fearing the enmity of the Moovendars, the two small land leaders refused to accept Kapilar's request. Kapilar, who was heartbroken and without Pari, wanted to die. Kapilar handed over Pari's daughters to a brahmin who was close to him and gave up his life from the north.

The Chemical Recovery boiler is the profit earning section of Paper Industry. By properly reutilizing the resources like wood, water and steam for manufacturing, there would be a chance of the paper cost can be reduced. To be the proper functioning of the boiler Soot blowers is necessary. There are 28 Soot blowers available in Seshasayee Paper Board Ltd., Pallipalayam, procured from Clyde Bergemann Inc., Atlanta, USA. Optimization of High-Pressure steam during soot blowing saves green energy and effectively controls the plugging tendency. The fouling management of the boiler was enhanced and the soot blowing steam consumption was reduced. Soot Blowing performed only where and when needed. This project focuses on how to reduce the high-pressure steam during Soot blowing process. Heat transfer from flue gas to water and steam to get maximum potential. This will increase the efficiency of the Recovery Boiler.

Sankarabarani river basin gains significance due to presence of major industrial, agricultural, urban development and tourist related activities has influenced the water quality in the estuarine environment. Investigations about river water quality has been attempted but not more studies focus about the evaluation of groundwater discharge a significant process that connects groundwater and the coastal seawater have been attempted. For the present study, radium (226Ra) a naturally occurring isotope was measured at three locations and used as effective tracers for estimating the groundwater discharge along with nutrient inputs to the Bay. Groundwater samples representing north east monsoon (December, 2017) has been collected during tidal variation in three locations (Location A- away from the coast towards inland, Location B-intermediate between Location A and the coast and Location C-at the estuary). 226Ra mass balance calculated groundwater fluxes irrespective of tidal variations were 2.27×108 m3/d, 2.19×108 m3/d and 5.22×107m3/d for A, B and C locations respectively. The nutrients like Dissolved inorganic nitrogen (DIN), Dissolved inorganic Phosphate (DIP) and Dissolved Silica (DSi) were found to be influencing the coastal groundwater by contributing fluxes to the sea of about 679.33 T mol/day. The study suggests increasing radium and nutrient fluxes to the Bay altering the coastal ecosystems would result in surplus algal blooms creating hypoxia.

Wireless Mesh Networking (WMN) is the latest Internet framework that provides a comprehensive range for Subsequent Internet (SI) prototype. Despite significant advantages provided by WMN, its practical distribution to connect Internet of Things (IoT) networks caused exorbitant congestion and restricted bandwidth. Motivated by this, a novel mechanism that ensures control in the manifestation of mobbing, end-to-end delay, energy consumption for enhancing the network performance of IoT-enabled WMN is presented. The proposed method is called as an Integrated Markov State Transition and Open Loop Smart Caching (MST-OLSC) for congestion control in IoT-enabled WMN. The proposed method uses Markov state transition scheduling model to differentiate the states of the incoming data packets from the host computer. This is performed by applying the State Betweenness centrality. Next, Congestion Control Token Caching mechanism is applied with the objective of controlling the congestion by means of caching via overflow with well-balanced isolation between regulated and unregulated flow of data packet. Finally, Open Loop Smart Caching is presented to ensure constant data rate, thereby providing fair inflow and outflow between the incoming and outgoing data packets. The evaluation results of MST-OLSC ensure higher network performance with minimum end-to-end delay, energy consumption and higher packet delivery rate is achieved with respect to inflated IoT nodes in WMN.

Cardiac diseases are the major causes of death in both developed and developing nations. As per WHO, it is estimated around 17.9 million people died due to cardiovascular diseases which accounts for 31% of all global deaths every year. More than 75% deaths occur in middle and low income countries. Globally, the main reason for the fatality of cardiac patients is Stroke and Heart attack, secondly the unavailability of doctors and insufficiency of hospitals with proper infrastructure in remote areas. Around the world, only few cardiologists are available, especially in developing countries like India; around 64 million peoples are suffering from different types of cardiac diseases with just about 4000 cardiologist. The ratio between the availability of cardiologist and cardiac patients varies significantly, which leads to alternative measures to monitor the patients from their respective places to prevent the death. In recent days Internet of Things (IoT) is the most innovative technologies that revolutionize the health care sector by providing modern medical devices for diagnosing, monitoring and treating patients with several diseases. IoT help the people who are at higher risk of getting diseases and make them to live a healthy life. This review paper is aimed to explore the benefits, applications and challenges of IoT based medical devices which are designed to diagnose and monitor the cardiovascular diseases and also give an insight about the overwhelming superiority of IoT in solving the problems arising due to heart diseases by expanding the medical resources and its availability.

This research aims at creating course equalization in a single cloud education portal. The existing course equalization process is done manually, which is not an efficient way and makes the task complicated. The prevailing technique is less accurate and a systematized storage is not available, as data are recorded and preserved by staffs of equalizing committee. Whereas, in this course equalizer software provides portal for information storage and retrieval whenever required. Being an education cloud storage its records can be easily accessed. In this pandemic situation, Education is made online. So difficulty arises in doing the transferring process manually for the students. So developing a course equalizer software provides a higher satisfaction for the transferring students and university staff. Students are enabled to know about their existing credits transfer and credits equivalencies, while transferring to other institutions. This cloud portal provides accurate course equalization service anytime and anywhere access. Similarly, the credit transfer for each course is done by examining the credit points given by the university. Credit transferring is a crucial task and it has many difficulties. The proposed work is done based on the algorithm Course Equalizer Based on HAIC search. Credits transfer plays a vital role in course waivers, where the students need not repeat the same courses completed at their previous institution. Courses may not always be the same at all institutions, thereby examining the core of courses becomes mandatory, which is difficult to get it done manually. Thus all these chaos can be resolved by upgrading us with this course equalizer software.

This research work proposes an enhanced pair-wise directional geographic routing (EPWDGR) technique using the directional antenna and compares it with the conventional pair-wise directional geographic routing (PWDGR) method that uses the Omni-directional antenna. PWDGR has two key limitations - minimum network lifetime and its use of static nodes. The EPWDGR technique aims to overcome these pitfalls by incorporating a directional antenna patch that requires lesser power, thereby increasing the network lifetime. The validations have been performed through simulations that use a random waypoint mobility model which is more practical. Varying performance metrics have been used for the estimation of network lifetime. The EPWDGR also solves the energy bottleneck problem at the nodes near the sink.

Phosphatidylglycerol is an essential phospholipid for photosynthesis and other cellular processes. We investigated the role of phosphatidylglycerol in cell division and metabolism in a phophatidylglycerol-auxotrophic strain of Synechococcus PCC7942. Here we show that phosphatidylglycerol is essential for the photosynthetic electron transfer and for the oligomerisation of the photosynthetic complexes, notably, we revealed that this lipid is important for non-linear electron transport. Furthermore, we demonstrate that phosphatidylglycerol starvation elevated the expressions of proteins of nitrogen and carbon metabolism. Moreover, we show that phosphatidylglycerol-deficient cells changed the morphology, became elongated, the FtsZ ring did not assemble correctly, and subsequently the division was hindered. However, supplementation with phosphatidylglycerol restored the ring-like structure at the mid-cell region and the normal cell size, demonstrating the phosphatidylglycerol is needed for normal septum formation. Taken together, central roles of phosphatidylglycerol were revealed; it is implicated in the photosynthetic activity, the metabolism and the fission of bacteria.
