Abstract

Dandruff is a common disorder affecting the scalp condition caused by yeast Pityrosporum. Dandruff cannot be completely eliminated but can only be managed and effectively controlled. Symptoms of dandruff mainly include Presence of fragments, Itching of the scalp, and Redness around the scalp. Dandruff can be treated in two ways. They include chemical based antidandruff shampoo and herbal based antidandruff shampoo containing antibacterial and antifungal ingredients like ketaconazole, selenium sulfide, zinc pyrithione etc. The anti-dandruff shampoo only slow down the scalp flaking and have their own disadvantages like loss of hair, increased scaling, itching, irritation, nausea, headache, vomiting, photosensitivity. Herbal extracts formulations are viable alternative to synthetic drugs. Now-adays, many herbal shampoos are available in the market which contains herbal ingredients such as plant extracts and essential oils. In the present review we discuss about the causes, synthetic chemical, various herbs and the evaluation parameters for the anti-dandruff shampoo.

Abstract

Integer factorization is one of the vital algorithms discussed as a part of analysis of any black-box cipher suites where the cipher algorithm is based on number theory. The origin of the problem is from Discrete Logarithmic Problem which appears under the analysis of the cryptographic algorithms as seen by a cryptanalyst. The integer factorization algorithm poses a potential in computational science too, obtaining the factors of a very large number is challenging with a limited computing infrastructure. This paper analyses the Pollard's Rho heuristic with a varying input size to evaluate the performance under a multi-core environment and also to estimate the threshold for each computing infrastructure.

Keywords

Abstract

Now a days the use of unmanned aerial vehicle (UAV) is getting common, as its size varies from small to large, which has good parameters like, light weight and good stability and can be used for surveillance, agriculture, and in defense as it can be controlled from ground or from other aircraft.

In an UAV wing is blended with fuselage which gives lift to the UAV and the tail is also used for take-off and landing which is also gives higher stability to aircraft. It is important to design an empennage structure at lower drag and for good stability characteristics.

In this present project airfoil coordinates has been generated by using JAVAFOIL, in this project NACA0010 airfoil is created, which is imported to CATIA V5 to design different empennage configurations of same wetted area and UAV empennage has been finally designed in a modeling tool CATIA V5 R19.The model is imported to Ansys through IGES file to simulate CFD analysis, where for analyzing fine meshing is taken for the whole structure of UAV and further CFD flow analysis is done through Ansys CFX software. The results for C_L, C_D and L/D are obtained by varying AOA with different velocity as shown in graphs (fig 13 to 18). A comparison is made for these empennages to check the aerodynamic efficiency and stability created by the different SUAV tails.

Abstract

Recently, more and more attention is paid to reversible data hiding (RDH) in encrypted images, since it maintains the excellent property that the original cover can be losslessly recovered after embedded data is extracted while protecting the image content's confidentiality. All previous methods embed data by reversibly vacating room from the encrypted images, which may subject to some errors on data extraction and/or image restoration. Here, a novel method is proposed so as to reserve room before encryption with a traditional RDH algorithm, and thus it is easy for the data hider to reversibly embed data in the encrypted image. The proposed method can achieve real reversibility, i.e., data extraction and image recovery are free of any error.

Abstract

The primary objective of this study was to identify natural isolates of fluorescent pseudomonads with superior antagonistic activity towards plant parasitic nematodes. Nematicidal potential of eighteen isolates of fluorescent pseudomonads were compared against peanut ischolar_main-knot nematode, Meloidogyne arenaria. Cell-free culture filtrate of DAPG-producing isolates of Pseudomonas putida caused significantly higher mortality of M. arenaria (J2) with highest in isolate DAPG3 (87.36%), followed by DAPG1 (84.16%) compared to other isolates of fluorescent pseudomonads, i.e., P. gessardii BHU1 and P. aeruginosa BM6 after exposure period of 72h at 100% concentration. The selected DAPG-producing isolates of P. putida caused significant inhibition in egg hatching. The lowest cumulative per cent hatch of M. arenaria was observed in the isolate DAPG3 (17.84%) followed by DAPG1 (18.10%). The isolates DAPG1 and DAPG3 also inhibited the nematode invasion in the ischolar_mains of peanut by 41.30% and 36.34%, respectively. Significant reduction in number of galls/plant in peanut ischolar_mains was recorded. The maximum reduction (51.30%) in ischolar_main galling was recorded with combination of seed treatment and soil application of P. putida DAPG1 followed by 41.73% in combined treatment of seed treatment and soil application of P. putida DAPG3. The levels of Peroxidase (POD), Catalase (CAT) and Polyphenol Oxidase (PPO) were non-significant in the leaves of peanut in the treatment that received P. putida DAPG1 and DAPG3, either as seed treatment and/or soil application, compared to inoculated and un-inoculated control. However, significantly enhanced phenol content was recorded in the leaves of peanut in the treatment that received combination of seed treatment and soil application of P. putida DAPG1 and seed treatment alone.
