 Abstract

Recently decentralized cloud storage platforms become the future of distributed web due to easy, reliable, robust, faster access, storing and sharing of data. In this paper we presented a comprehensive study on decentralized cloud storage IPFS, FileCoin, Sia, Swarm and Storj platforms. These platforms are the backbone of an internet due to storage of huge amount of data. From the era of Web 1.0 of centralized system to Web 2.0 decentralized approach, now Web 3.0 of distributed decentralized web with use of IPFS, Sia, and Swarm and Storj storage platforms. Interplanetary File storage and FileCoin replaced HTTP traditional protocol. They worked on the requirements of the user with online backup services. All of these cloud platforms works on needs of the user for decentralized peer to peer storage but different in their implementation part. Further this paper studied the uses, advantages, disadvantages and their issues related to decentralized file systems.

 Abstract

The performance of the page replacement algorithms can be improved by augmenting it with some data along with the algorithm design. This can indeed optimize the time taken for the swapping process. In this system we are augmenting two data structures with LRU page replacement algorithm, they are doubly circular linked list and hash table. Doubly circular linked list is used because the traversal between the nodes is easier and faster. Hashing is more efficient in performing optimal searches and retrievals because it increases speed, better ease of transfer, better retrieval and reduce overhead. Furthermore Hashing can reduce disk space and access time by inserting and retrieving a page from the main memory in only one seek. Further we are comparing the performance of the classical LRU page replacement algorithm with the augmented LRU page replacement algorithm in terms of runtime.

 Abstract

The natural integration of nanoparticles is a transformative process in the field of nanotechnology. Lanthanum nanoparticles have been used in various fields. In the present study, the extraction of bitter gourd was used to synthesize lanthanum nanoparticles. Visible UV spectroscopy was used for quantification. Integrated lanthanum nanoparticles identified by Fourier transform Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD) and synthetic lanthanum nanoparticles have shown excellent anti-inflammatory activity.

 Abstract

The present data is of different features of fishes out of which Weight is a response variable and others, Length1, Length2, Length3, Height, and Width are predictors. The present study is carried out with two reasons:- 1. To point out the important predictors. 2. To obtain the appropriate regression model.

 Abstract

Airport runways are built to exacting, internationallymandated standards. But frequent landing and take-off of flights lead to wear and tear of runways. Natural weather phenomena like rain and sun also affect the runway surface.Re-carpeting is essential for the safety of flights. All re-carpeting activities on runways are likely to lead to flights being rescheduled though they are not always cancelled or disrupted. Airport runways at all times need to be of a specified strength or Load Classification Number (LCN), which is a system of classification of the supporting capacity of pavements without cracking or becoming permanently deformed. Airport pavements are constructed to provide adequate support for the landing. In order to satisfactory, the pavement must be with quality and adequate thickness that it will not fail under the loads. In addition, it must possess sufficient inherent stability to withstand, without damage, the abrasive action of traffic, adverse weather conditions, and other deteriorating influences. To produce such pavements requires a coordination of many factors of design construction, and inspection to assure the best possible combination of available materials and a high standard of workmanship. The paper deals with the various methods involves in strengthening of runway pavement by examining the runway for a variety of issues including whether the aircraft is having a smooth ride as it lands, rubber deposits and removal, raveling observed at touchdown zone and rubber removal area, reflection cracks, patching on runway, pop outs and coarse aggregate loss, alligator cracking, surface irregularities on the line markings, shoving and uneven surface. Software results by considering number of flights along with loading damage ratio is calculated which results in thickness for re-carpeting further this ratio is considered for thickness of pavement if number of flights increase.

 Abstract

Medicinal plants are the local heritage with universal importance. World is gifted with a rich wealth of medicinal plants. Herbs have always been the principal source of medicine in India and presently they are becoming popular throughout the world. Plants have played a significant role in maintaining the quality of human life for thousands of years and served humans as with cosmetics dyes and medicines. Traditional medicine is the oldest method of curing diseases and infection and various plants have been used in different parts of the world to treat human diseases and infection. Medicinal plants are known to owe their curative potentials through certain biologically active substances which exist in different parts of the plants. The major lacuna is the lack of proper identification and information about the medicinal plants. Justicia tranquebariensis belongs to the family Acanthaceae. Mostly the leaves are used for the medical purpose. It is one of the most important herbs being used in Ayurvedic system of medicine. Predominantly, the leaves are used for several medicinal purposes. A wide variety of biologically active constituents such as Phytosterol, Flavonoids, Glycosides, Steroids and Phytosteriods, Coumarins, Cardiac Glycosides, Glycosides, Terpenoids, Carbohydrate, Amino Acids, Gums and Mudilage, Saponins, oil and fats are present in this plant. It exhibits antioxidant, hepatoprotective, antihelmethic, cardioprotective, antiulcerogenic, bronchial asthma, anti-arthritic and antimicrobial activities. This review will focus on the phytochemical constituents isolated from the plants and phytopharmacological properties of different parts of Justicia tranquebariensis.
