A Study on Fundamental Theorem of Galois Theory

In [F] the theoretical Galois hypothesis, initially created by Krasner for automorphism gatherings (and in this manner endomorphism monoids) of social structures and afterward stretched out by others for not really finitary multi-contention tasks, was inferred by a predictable utilization of the list changes under which the safeguarded relations are invariant. The limited length of that communication blocked an express show of a last structure or a correlation with different definitions inferred by different methods. It is proposed to make this up here, inferring and examining the other surviving structures based on this one

Ransomware protection in IoT using software defined networking

Internet of things (IoT) is the network of physical objects connected to provide various services. IoT is expanding rapidly, and is positively influencing many areas. The impact of IoT is evident in medical field, manufacturing units and livestock. The IoT is also vulnerable to many cyber threats, owing to its limited resources and battery operation. In contemporary times the security threats like DDoS, botnet malware, man in the middle, flood attacks and ransomware are affecting the smooth functioning of IoT. Ransomware has emerged as one of the biggest threat in cyber world. Ransomware is a type of malware that stops the access to files by encrypting them and decrypts the files only when a ransom is paid. The negligence towards the IoT ransomware can result in disastrous outcomes. In this paper, the growth of ransomware attacks for past few years is shown with special focus on ransomwares threatening IoT. A detection mechanism for IoT ransomware attack is presented that is designed after study of ransomware for IoT. The proposed model monitors the incoming IoT traffic through Software Defined Network (SDN) gateway. It uses policies framed in SDN controller for detection and alleviation of ransomware in IoT

Analysis of EDFA-WDM Optical Network System

In WDM systems optical fibers are utilized to transmit data in type of light pulse between the transmitter and the receiver. WDM frameworks can possibly transmit multiple signals at the same time. However, the light signal decreases in power when they travel a long distance inside the fiber. So it is required to intensify all the light signals at the same time after a specific interval of light spread to recover the first signal. Optical amplifiers are for the most part used to regenerate the light pulses. There are numerous optical amplifiers. One of the normal amplifier utilized is Erbium Doped Fiber Amplifier. In this paper the investigation of WDM system is done on the basis of Erbium Doped Fiber amplification and dispersion compensation mechanism utilizing Optisystem programming

Awareness About Denture Cleaning Aids Among Dental Students of Private Dental Institution

The oral health of the denture wearing patients plays a significant role related to quality of life, nutrition, social interactions and general systemic health. The dentists must be aware about the cleaning of dentures since they design the denture for patients comfort and function.The aim of the study was to assess the awareness of denture cleaning aids among dental students in a private dental institution. A survey was conducted in December 2019 among dental students (Third years, Final years and Interns) of saveetha Dental college. It was an online questionnaire based study, conducted to assess the awareness of denture cleaning aids. 150 dental students participated in this study. The survey consisted of 8 questions related to denture cleaning aids, conditions associated, method of cleaning etc. The survey was distributed to the students through google forms and the data collection was done. Chi square statistical analysis was done using Statistical Package for the Social Sciences software(version 20). It was found that awareness of denture cleaning aids is seen maximum in 30.67% of interns compared to III years and IV year students. Within the limitations of the study it was found that interns were more aware about denture cleaning aids compared to third years and final year students

In vitro callus induction in rice (Oryza sativa L.)

In vitro callus induction from embryos of matured seeds of four rice varieties viz.,ASD 16, ADT 43, Basmati 370, Pusa Basmati and Pokkali were studied. Observations oncallus induction were carried out on six different callus induction medium having differentconcentration of 2,4-D viz., 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 mg/l. The callus induction frequencyvaried from 58.33 % to 96.67 %. This study will be useful for selecting suitable callusinduction medium for callus induction

Baseband Data Handling System Using LEON3FT Processor

The data handling system is used to receive the data from the payloads of the satellite and format the data into suitable form so that it can be successfully received at the ground station. Data handling system consists of payload interface unit, preprocessor unit, data compression unit, data encryption unit, and channel coding and frame formatter. Till now, data handling systems were developed with the help of FPGAs. The current project involves the development of on board data handling system based on LEON3FT processor. Processor provides the advantages of reduced hardware complexity, programmability and computational performance

Oscillation Criteria of Second-Order Quasi-Linear Neutral Delay Difference Equations

2000 Mathematics Subject Classification: 39A10.The oscillatory and nonoscillatory behaviour of solutions of the second order quasi linear neutral delay difference equation Δ(an | Δ(xn+pnxn-τ)|α-1 Δ(xn+pnxn-τ) + qnf(xn-σ)g(Δxn) = 0 where n ∈ N(n0), α > 0, τ, σ are fixed non negative integers, {an}, {pn}, {qn} are real sequences and f and g real valued continuous functions are studied. Our results generalize and improve some known results of neutral delay difference equations

Effect of immunostimulant on enhancement of the immune response of kuruma shrimp Marsupenaeus japonicus and its resistance against White Spot Syndrome Virus (WSSV)

An experiment of 45 days duration to test the efficacy of the Vibrio alginolyticus as an immunostimulant was conducted in Marsupenaeus japonicus against white spot syndrome virus (WSSV) infection, considered as one of the serious pathogens of shrimps. The shrimps were fed with the experimental diets coated with different concentrations of bacteria of 17 ml / kg feed and 10 % of animal body wt. They were challenged with WSSV to assess the increase in survival rate and growth if any due to immune enhancement. Another group of shrimp was used for drawing the haemolymph to estimate the increase in the level of prophenoloxidase activity. Samplings for the above said analysis were carried out at 15 days interval for a period of 45 days. The highest prophenoloxidase activity (39.78 with sand substrate-T1) and the highest survival rate (66.66 % with sand substrate-T1) and highest growth rate (7.04 % in 17ml/kg- with sand substrate-T1) were recorded in experimental diet (17 ml / kg feed). Hence the 17 ml / kg feed of Vibrio alginolyticus formalin killed added to the diet could be an eco-friendly and economically viable immunostimulant for penaeid shrimps
