We hereby describe a novel method of electrophoretic analysis of bacterial cell proteins prestained with a new reactive dye Coomassie Brilliant blue R-250 (CBB). The proposed method was standardised by studying as many as 950 disc electrophoretic separations, 50 variables, 60 isolates of Salmonella typhi and two standard NCTC S. typhi control strains. Under the critical conditions the cell free extract (CFE) of Salmonella and the soluble dye (8.5 mg/1 ml), Tris-glycine buffer (1:10), pH 8.3 was mixed in equal proportions, conjugate warmed at 41°C for 2 hours to ensure a stable covalent binding. 100 microlitre of this conjugated CFE was analysed by Polyacrylamide gel disc electrophoresis (PADGE). The method when compared with the post electrophoretic staining by Amidoblack revealed that the prestained discs were intensely well defined with a transparent gel. The amidoblack stained gel even with prolonged destaining showed a residual dye retention making identification of the faint components difficult. Proteins eluted from CBB-prestained gels retained its immunoreactivity, immunogenecity, purity and conjugates of Salmonella cell protein (mol. Wt. 69000) produced high titre monospecific antisera in immunised rabbit.

With the increasing use of antibiotics, self medication and easy availability of antibiotics over the counter, the number of potential victims of Antibiotic associated diarrhoeas (AAD), either in its mild form or serious sometimes fatal disorder may be a force to reckon with. Understanding the pathogenesis, high risk factors and means of prevention may help us rto avert or effectively treat this disorder. Antibiotic associated diarrhoea is caused by Clostridium difficile, Clostridium perfringens, Staphylococcus aureus, Klebaiella oxytoca, Candida spp and Salmonella spp. Nearly 25% AAD is caused by Clostridium difficile making it the commonest identified and treatable pathogen. Most mild cases of AAD are due to non-infectious causes which include reduced break down of primary bile acids and, allergic or toxic effects of antibiotic on intesrtinal mucosa and pharmacological effect on gut motility. The antibiotics most frequently associated with C. difficile associated diarrhoea are clindamycin, cephalosporin, ampicillin and amoxycillin. The most sensitive and specific diagnostic tesrt for C. difficile infection is tissue culture assay for cytotoxicity of toxin B. Commercial ELISA kits are available. Most of the times, discontinuation of the inciting antibiotic along with enteric precautions and isolation to prevent its spread, is sufficient. However at times, treatment with antibiotics like metronidazole, vancomycin may be required. Relapses may occur which may require re-therapy with metronidazole/vancomycin, or at times treatment with anion binding resins and probiotics. Probiotics have been shown to have a role in the prevention of AAD {recurrent cases}. In recent years, AAD has been increasing in frequency and severity due to the emergence of virulent strains.Keywords

Distributed flexible AC transmission system (DFACTS) devices offer many potential benefits to power systems. This paper examines the impact of installing D-FACTS devices by studying the sensitivities of power system quantities such as voltage magnitude, voltage angle, bus power injections, line power flows, and real power losses with respect to line impedance. These sensitivities enable us to identify and develop appropriate applications for the use of D-FACTS devices for the enhanced operation and control of the grid. Specific applications of D-FACTS devices for line flow control, and voltage control are investigated.- Performance Analysis of Load Balancing Algorithms Using Qualitative Parameters:A Review

Load balancing algorithm tries to balance the total system load by transparently transferring the workload from heavily loaded nodes to lightly loaded nodes, to ensure good overall performance. In this paper the performance analysis of various load balancing algorithms based on different qualitative parameters, considering static and dynamic load balancing approaches are considered. The analysis indicates that these both types of algorithms can have advancements as well as weaknesses over each other. Decision of type of algorithm to be implemented will be based on type of parallel and distributed applications to solve. The main purpose of this paper is to help in design of new algorithms in future by exhaustive study of behavior and characteristics of various existing algorithms.Keywords

Assessment of clean speech from a noisy speech signal has been a research topic for a long time. This research finds its variety of applications, which includes the present mobile communication also. The most important outcome of this research is the improved quality and reduced listening effort in the presence of an interfering noise signal. In this paper the performance of various noise reduction techniques namely spectral subtraction, wavelet transforms, iterative subtraction, MMSE and Wiener filtering is done. This paper proposes a time-frequency estimator for enhancement of noisy speech signals in the discrete frequency transform domain. In the proposed method the estimation is based on modeling and filtering frequency components of noisy speech signal using Kalman filters. Experimental outcome show that the proposed method provides the better performance as compared to the other Spectral processing approaches.

This paper presents a methodology for maintenance scheduling (MS) of generators using binary particle swarm optimization (BPSO) based probabilistic approach. The objective of this paper is to reduce the loss of load probability (LOLP) for a power system. The capacity outage probability table (COPT) is the initial step in creating maintenance schedule using the probabilistic levelized risk method. This paper proposes BPSO method which is used to construct the COPT. In order to mitigate the effects of probabilistic levelized risk method, BPSO based probabilistic levelized risk method is embarked on a MS problem. In order to validate the effectiveness of the proposed algorithm, case study results for simple five unit system can accomplish a significant levelization in the reliability indices that make possible to evaluate system generation system adequacy in the MS horizon of the power system. The proposed method shows better performance compared with other optimization methods and conventional method with improved search performance.Keywords

The present study was designed to investigate the modifying effects of Mosinone-A on glycoconjugates (protein bound hexose, hexosamine, total sialic acid and fucose) levels in 7,12-dimethylbenz(a) anthracene (DMBA) induced hamster buccal pouch carcinogenesis 0.5% DMBA painting (three times per week) in hamster buccal pouches for 14 weeks resulted in the formation of well developed oral squamous cell carcinoma. We observed 100% tumor formation with marked abnormalities of glycoconjugates status in tumor bearing hamsters as compared to control animals. Oral administration of Mosinone-A at a dose of 2 mg/kg body weight, to DMBA painted hamsters on alternate days for 14 weeks, reduced the tumor formation as well as protected the levels of cell surface glycoconjugates in DMBA painted hamsters. The present study thus suggests that Mosinone-A has potent chemopreventive efficacy as well as protected the abnormalities on cell surface glycoconjugates during DMBA induced hamster buccal pouch carcinogenesis.Keywords

Cancer is one of the dangerous diseases faced by humans. Every one out of 100 women is facing breast cancer. So, to overcome this huge ratio many researches are being carried out. Prevention is better than cure; this paper presents one such attempt of detecting breast cancer in the early stages. In proposed method exponential point transform is carried out for image enhancement and in preprocessing stage pectoral mass is removed from the mammogram image. As the next step we apply K-means algorithm and morphological processing to identify the infected region and removal of unwanted region. Finally, Decision Tree Data mining technique is used for classifying features to detect presence of tumor. Hence by this approach we get more accurate results. The experimental results gave an accuracy of 97.03 %.Keywords

A field experiment with two methods and three levels of irrigation using crop factor was carried out on eighteen years old oil palm plantation at ICAR-Indian Institute of Oil Palm Research, Pedavegi to find out their influence on vegetative growth and yield of fresh fruit bunches during the year 2016-2017. The data obtained have indicated non-significant differences for most of the parameters evaluated. However, application of irrigation water through drip method at crop factor 0.8 recorded highest number of leaves produced (25.83), highest number of female inflorescences (7.16), lowest number of male inflorescences (5.12) which contributed to increased production of number of fresh fruit bunches (7.16), total weight of FFBs (148.44 kg/palm/year) thereby FFB yield (21.23 t/ha). Further, the same treatment combination has increased percentage of fruits to the bunch (64.79%).Keywords

The paper presents the design and development of Terrain Mapping Camera-2 (TMC-2) for Chandrayaan- 2 including science objectives; system and sub-system configuration along with the realized performance of the camera; payload characterization; aspects related to data products, etc. TMC-2, onboard Chandrayaan-2 orbiter-craft is a follow-on of the Terrain Mapping Camera (TMC) onboard Chandrayaan- 1. It operates in visible panchromatic band. It comprises three identical electro-optical chains aligned for three views (–25, 0 and +25 degree) along track direction for generation of stereo images. It provides data with 5 m horizontal ground sampling distance to generate digital elevation model. TMC-2 based on the new configuration and sub-system designs has reduction in mass and power by more than 40% compared to TMC, without compromising the performance.Keywords

This paper provides the solution for smart mobility to the people who are unfamiliar with the routes on campus. The proposed automated evehicle contains four wheels - one wheel at the front end and three wheels at the rear end to get a proper balance. It also contains a keyboard Switch with which the user keys their destination point as an input to the system. It is programmed to take the travelers automatically to the destination based on the input provided by the travelers. This is done by automating the main controls like accelerator, brakes and hand bar. Each control is handled by an individual motor. The Servomotor is used to control acceleration whereas the braking and steering of hand bar are controlled by 12V and 24V geared DC motor. Brushless DC motor (BLDC) of rating 48V is used as a main drive. It is responsible for the movement of vehicles. To accomplish zero chance of accident occurrence, ultrasonic sensors are employed. Three numbers of ultrasonic sensors are placed at the front of the vehicle. These sensors help us to detect the obstacle along its way. It gives out a signal when any obstacle is sensed. Global Positioning System (GPS) module helps up to identify the vehicle location on the Earth by coordinates in the form of latitude and longitude. Through this module, the coordinate that the vehicle has to travel is identified and fed into the Arduino microcontroller. At every instance, the present location of the vehicle is compared with the pre-loaded coordinates. Finally, the Arduino microcontroller works with the data from these components and generates the control signals to drive the vehicle in a programmed route. The developed simple Cybernetic E Vehicle is tested in real time.Keywords
