Radiation and Mass Transfer Effects on MHD Viscous Flow Past an Impulsively Started Vertical Plate through a Porous Medium

In this paper we have analyzed the effects of Radiation and mass transfer on MHD viscous flow. The flow is assumed to be past an impulsively vertical plate in porous medium. The governing equations of the flow are solved numerically using finite difference scheme. Finally the influence of various physical parameters involved in the equations of velocity, temperature and concentration are discussed through graphs. More over through this numerical study, we observed that velocity as well as temperature profiles decreases with an increase in Radiation parameter. Increase in Magnetic and permeability parameters decreases and increases the velocity respectively. Keywords: MHD, Radiation, Viscous dissipation, Vertical plate, Finite difference scheme

Central Pivot Heuristics for Botnet Attack Defense in Iot

Botnet assaults on IoT systems have become a big issue, and several strategies for botnet protection have been investigated by the academic and industry communities. While many of these methods are practical and effective for botnet attack prevention, one of the important limits is the load factor on the servers that manage monitoring and control in addition to catering to client system requests. To address load factor difficulties, the focus of this study report is on the conditions of installing a four-layer security control system based on the notion of central pivot points. Inspired by the effective and systematic Markov Chains concept, this publication proposes a four-layer filtering model that shows if botnet detection and prevention methods for servers are required. The model's simulated experimental study demonstrates the potential scope of deploying the system. The study also highlights the future possibilities of model improvisation that can reduce any erroneous signal production that is judged necessary

The Extension of Generalized Intuitionistic Topological Spaces

In this paper, irresolute functions in generalized intuitionistic topological spaces were introduced. Regarding this function, some minimal and maximal irresolute functions were introduced. In addition, the generalized intuitionistic topological spaces were extended by using their open sets which is finer than of it and their basic characterizations were investigated. Also some continuous functions in extension of generalized intuitionistic topological spaces were discussed

Biochemical and molecular mechanisms of resistance to Helicoverpa armigera (Hubner) in wild relatives of Chickpea

The present studies on “Biochemical and molecular mechanisms of resistance to Helicoverpa armigera (Hubner) in wild relatives of chickpea” were carried out at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Patancheru, during 2014-16. A total of 20 accessions (15 wild relatives and five varieties of cultivated chickpea) were used to evaluate the mechanism of resistance to H. armigera. Under field conditions, during post-rainy seasons 2014-15 and 2015-16, all genotypes of wild relatives of chickpea recorded less number of H. armigera larvae, low visual leaf damage rating and per cent pod damage compared to cultivated chickpea. The genotypes IG 70012, PI 599046, IG 70022, PI 599066, IG 70006, IG 70018 (Cicer bijugum), ICC 506EB, ICCL 86111 (resistant checks), IG 72933, IG 72953 (C. reticulatum) IG 69979 (C. cuneatum) and IG 599076 (C. chrossanicum) showed high levels of antixenosis for oviposition of H. armigera under multi-, dual- and no-choice cage conditions. Studies on detached leaf assay revealed that the genotypes IG 70012, IG 70022, IG 70018, IG 70006, PI 599046, PI 599066 (C. bijugum), IG 69979 (C. cuneatum), PI 568217, PI 599077 (C. judaicum) and ICCW 17148 (C. microphyllum) showed less damage rating and low larval weights compared to susceptible checks. Larval survival was greater on the wild relatives than on the cultivated chickpea. Detached pod assay studies revealed that all wild relatives of chickpea exhibited less damage rating, lower per cent pod damage and lower percentage of weight gained by third-instar larva compared to cultivated chickpea. Survival and development of H. armigera on artificial diet impregnated with lyophilized leaf powders revealed that all wild relatives of chickpea genotypes showed high levels of antibiosis to H. armigera compared to cultivated chickpea in terms of lower larval survival, per cent pupation and adult emergence, decreased larval and pupal weight, prolonged larval and pupal developmental periods and reduced fecundity

Evaluation Changes of Lungs in Asthmatic Rats Treated with Aqueous and Non Aqueous Extract of Clerodendrum Serratum and Theophylline.

The present study Asthma is one of the common disorders encountered in clinical medicine in both adults and children are asthma and it is characterized by inflammation of the airways which causes airway dysfunction. Asthma is currently a worldwide problem with around 300 million people around the global suffering from it and world deaths of about 25000 annually. Inhaled bronchodilators and anti inflammatory drugs are available and effective and they require long term use and are associated with side effects. This is why alternative and complementary medicine is being sort after to prevent these side effects. Several medicinal plants have anti inflammatory effect and have proved effective in the treatment of asthma. Clerodendrum serratum Linn (Family-Verbenaceae) is very widely distributed in tropical and subtropical regions of the world. Citric acid, Acetylcholine, Histamine is mainly used for evaluating anti asthmatic activity of particular drug. This review contains list of medicinal plant which have been tested for anti asthmatic activity in the Citric acid, Acetylcholine induced asthmatic in Rat model Thus, the information provided in this research will help the researchers for the development of an alternative methods rather than inhalers and oral anti asthmatic drugs for the treatment of asthma and COPD which will minimize the complication. Many plants obtained from the natural source play a significant role in the health care system. Literature survey on herbal drugs has shown significant anti asthmatic activity which has not shown any remarkable side effect. The pharmacological mechanism which the phyto constituents producing the anti asthmatic activity are not clearly understood till date. The several herbal formulation have derived from the Ayurveda, traditional system of Indian medicine and its additional system of medicine, yet to be scientifically validated that they have exhibited pharmacological action against Asthmatic. Only less number of scientific data of traditional medicines is available for the treatment of Asthmatic. CONCLUSION: On the basis of the result in these experiments, this may be stated that the aqueous extract of Clerodendrum serratum 200mg/kg has a beneficial effect in asthmatic patients. It will reduce the alveolar thickness and Eosinophils counts in blood further studies are required to purify the active principle and to study the molecular mechanism of the exact pathway. Non aqueous extract of Clerodendrum serratum (400mg/kg) having fewer amounts of steroids and flavonoids because it will filter the all compounds and reduce the quantity of chemical moieties. But aqueous extract of Clerodendrum serratum (200mg/kg) having higher amount of chemicals when compare to Non aqueous extract of Clerodendrum serratum (400mg/kg) so it will produce anti asthmatic at equal to standard drug. In lungs alveolar thickness reduced by the AECS 200mg/kg as equal to standard drug and also it’s same as normal lungs. So aqueous extract of Clerodendrum serratum having good beneficial effect for the asthmatic patients. This information’s will be useful for the development of alternative method rather than anti asthmatic agents (Inhalers, Tablets, Injections, Nasal sprays, Respules) for the treatment of Asthmatic patients. This will minimize the wheezing and or asthmatic symptoms

ENHANCED PRODUCTION OF PSORALEN THROUGH ELICITORS TREATMENT IN ADVENTITIOUS ROOT CULTURE OF PSORALEA CORYLIFOLIA L.

Objective: The present study aimed to determine the effect of two elicitors namely Methyl Jasmonate (MeJ) and Salicylic acid (SA) on adventitious root production of Psoralea corylifolia L. as the elicitors and at different concentrations.Methods: Adventitious roots of P. corylifolia L. were treated with different concentration of elicitors such as MeJ (10, 20, 30 and 40 µM/l) and SA (50, 100, 150 and 200 µM/l) to enhance the psoralen contents. After the treatment, psoralen content was analyzed through the analytical HPLC experiments (Methanol: Water (50:50) at 0.8 ml/min-1 flow rate and the injection volume as 20 µl).Results: MeJ and SA treatments at the concentrations of 30 µM/l and 150 µM/l respectively were found to increase the net wet weight of adventitious root production to 8 fold at 8 hours of elicitor treatment periods. Further, the quantity of psoralen was determined from the elicitors (MeJ and SA) treated roots and mother plant through the analytical HPLC experiments in order to estimate the psoralen content and it was found as 3.73 mg/ml, 0.015 mg/ml and 0.56 mg/ml respectively.Conclusion: In the present study we achieved enhanced production of psoralen through abiotic elicitors (MeJ and SA) treatment and concluded that the MeJ at 30 µM/l concentration shows significant enhancement of psoralen production.Â

Predictive maintenance and fault diagnosis of hydraulic gear coupling of a boiler feed pump unit

Increasing demand for reliability and performance of today’s most complex machines, and maintaining high productivity without sacrificing product quality have made it imperative for maintenance engineers to devise newer strategies in maintenance of plant and machinery. One of such strategies is condition monitoring, which has emerged as one of the most powerful technology in maintenance engineering. Condition monitoring and diagnostic engineering is a novel concept which enables us to detect in advance any incipient failure with ease and confidence in any part of a dynamic system before such failure trigger – off various types of failure mechanisms, which in turn may render the whole system uneconomical, unreliable, unhealthy, unsafe and even lethal. The present work highlights an experimental investigation to monitor the vibration behavior of hydraulic gear coupling, which is a part of Boiler Feed Pump train of a large utility Thermal Power Plant.  The coupling is supported by 4 Bearings. Tri-axial measurements are made at the bearing supports for 12 months. Displacement and Velocity are measured along Horizontal, Vertical and Axial directions. The experimental data is plotted on Time domain for graphical analysis to ease viewing of vibration signals. Based on the experimental data, faults are diagnosed using ISO – 2372 standards and causes are predicted. It is observed that the front and rear bearings of Input and output shafts of coupling are experiencing excess vibration. The work is concluded by suggesting remedial measures to ensure vibration intensity, at the said points, within the safe limits.&nbsp
