Study of risk associated with cross-infection in different occupational and routine public places

A total of fifty samples were selected to study cross-infection among different occupational workers and public dealing places, of which forty-four samples were randomly selected from peoples engaged in different occupations, four samples from public urinals and two samples from the keyboards of public dealing places. It was reported that out of the fifty samples, thirty three samples were found positive for growth of mixed colonial morphology of microorganisms on nutrient agar and blood agar media. Nineteen samples showed positive growth out of 34 samples taken from intact hands, all the six samples showed positive growth taken from infected hands and three out of four samples showed positive growth from injured hands. Further, all the four samples taken from public urinals showed profuse growth with different colonial morphology and one sample showed characteristic growth from the two keyboards samples.

Redesign of traffic signal timing for minimal delay of Chamrajpete junction in Bengaluru city, India

This research is intended to highlight the delay occurred by the vehicular traffic at Chamrajpete traffic signal junction. Also, the time and fuel loss by the vehicle user at the same junction due to the split-green time at Road 1- Basavanagudi Road (Bull Temple Road) and Road 2- Sirsi Circle Road. Hence, the redesign of traffic signal timing for the minimal delay is studied and the improvements are suggested to overcome the delay at the junction.

Review Paper

White spot lesions and their management

White spot lesions develop as a result of a dietary carbohydrate and saliva modified bacterial infection, resulting in an imbalance between demineralisation and remineralisation of enamel. The lesion is caused by the accumulation of plaque and bacteria along with insufficient oral hygiene. High plaque accumulation can increase the risk of white spot lesion formation. The dynamic balance between demineralization and remineralization determines the progression of white spot lesion. The diagnostic armamentarium includes novel technologies and non-invasive techniques like fiber-optic transillumination and electrical resistance methods which are very useful in detecting posterior approximal dentinal caries and occlusal caries. Radiographs and direct digital imaging are still important tools in the estimation of caries. A clear understanding of the mechanism of subsurface lesion formation and progression, possibilities, and limitations of newer methods and their clinical applications need to be recognized by the dentist to direct preventive strategies to the high caries risk individuals.

CFD analysis of heat transfer enhancement in a pipe with or without circular insert

This work presents a CFD analysis of heat transfer problem. The enhancement of heat transfer with mass in a tube has been investigated without and with insert. The combinations of without inserts, two inserts, four inserts, six inserts, eight inserts and ten inserts have been used. An 800 mm long pipe with 26 mm inner diameter and 30 mm outer diameter is considered for our simulation. 5. It is observed that outlet temperature increases to 313.15 K when two inserts are being fitted into the tube. We get the lowest outlet temperature for ten inserts. Therefore after 8 inserts outlet temperature decreases.

Review Paper

A review on CFD analysis of heat transfer enhancement in a pipe with or without circular insert

High-performance heat transfer system is of great importance in many industrial applications. The performance of conventional heat exchangers can be substantially improved by a number of heat transfer enhancement techniques. A variety of complex, highly viscous liquids are involved that undergoes heat exchange process while flowing through heat exchangers. Because of their vicious nature, they tend to have low flow rates and generally represent the dominant thermal resistance due to their vicious nature, adversely affecting the size and cost of the heat exchanger. The process industry is continuously working to incorporate enhancement in heat transfer. Enhancement techniques can be classified as active methods, which require external power or Passive methods, which require no direct application of external power. The enhanced surfaces are routinely used to improve the thermal and hydraulic performance of heat exchangers.

Survey paper on data aggregation in MANET with advance security protocol using NS2

Wireless sensor networks (WSNs) consist of sensor nodes and these nodes can vary from a few numbers to a highly dense number. Data aggregation is a very important technique in wireless sensor networks through which diverse parameters performance can be increased effectively. Energy consumption by nodes can be decreased using data aggregation technique by eliminating redundancy because these parameters play a vital role in MANET. Wireless sensor nodes are very tiny in size and have limited processing capability very low battery power. This diminution of low battery power makes the sensor network vulnerable to failure. Sensor networks consist of several sensor nodes which co-operatively send sensed data to base station. One of the critical constraints of sensor nodes is the power consumption requirement. As sensor nodes are battery driven, an efficient utilization of power is essential to reduce data traffic inside sensor networks thus reduce the amount of data that need to send to base station thereby enhancing the network lifetime. In this survey paper, our main focus is to know data aggregation, data aggregation strategies, private key, public key, and security concept how to data can be a guard from hackers or malicious nodes. Networks have huge application in habitat monitoring, disaster management, security, and military, etc.
