 Abstract

This paper focuses on preemption system for infrastructure like bridges. The stability of the structure is directly related to the structural strength. The structural analysis of such a bridge can be analyzed using vibration pattern and comprehensive study. MEMS based accelerometer is used to analyze the vibration patterns. The vibration signal measured by the node is communicated over WSN. Three levels of vibrations are detected. If the vibrations are in Safe level no action is taken. If the vibrations are in warning level a signal is sent to the monitoring person through RF. If the vibrations are in critical level then the bridge is closed for traffic. The inspection of building structures especially bridge structures is currently made by visual inspection. Structural health monitoring is a field that relies on different methodologies to develop procedures that characterize the dynamic properties of physical structures to identify possible deteriorations of their behaviors. The few non visual methodologies make use of wired sensor networks, which are relatively expensive, vulnerable to damage, and time consuming to install. Systems based on wireless sensor networks should be both cost efficient and easy to install, scalable and adaptive to different type of structures. Acoustic emission techniques are an additional monitoring method to investigate the status of a bridge of its components. Micro-Electro-Mechanical-Systems (MEMS) and hybrid sensors form the heart of network nodes

 Abstract

This study was conducted to clarify the difference in therapeutic effects between traction and yoga. Yoga is based on the structure and function of the human body because yoga practice gives special importance the relationship of the breath and the spine. The vertebral column problems like neck and back pain are very difficult to live and can affect every part of the life. Spinal column problems are treated many types of methods like physical therapy, hot/cold therapy, alternative medicine treatment, pain medications, massage are get back to normal and confortable activity. However, if tried the treatments weeks or months with reduction the pain. The physical therapy particularly the spinal traction is increase between the vertebrae, relaxing the pressure on vertebral discs, nerve roots, ligaments muscles and increase blood flow to the area making it heal much faster. The devolpment and monitoring of spinal traction was necessary for weeks or months and cost effective treatment to the patients. The comparative study improve the appropriate therapy and reduce the economic burden and adverce contra indications. Yoga therapy should be closely monitor for cost, safety and potency.

 Abstract

Indian society is a society in transition facing new opportunities and challenges in every walk of life. Sometimes there are socio cultural factors which pose a threat for any positive change in the society and the other time there are individuals who try to move against the stream in order to be more like the westerners . In addition to that there are lifestyle factors which pressurizes the individuals mentally and they become drug abuser in order to avoid the stress. As per a survey conducted by National Survey on Drug Use and Health, in America only, there are around 28.50% of population over the age of 12 and above facing future threats from drug abuse. The trend which is being followed in India was reported by United Nations International Drug Control Programme reveals that out of 2831 drug abusers studied, 251 i.e. 8.9% were women. Some other researches in this direction reveals the ill effects of drug abuse and ample evidences are there which proves that use of certain legal and illicit drugs pose real threats to the developing foetus and neonate. This paper tries to trace the overgrowing pattern of drug abuse among women in India and its consequential effects on their reproductive health. Also, this paper seeks to find out various measures in the light of social work perspective to mitigate the same.

 Abstract

The strength and durability of the concrete is dependent on curing. Self curing concrete can be used where curing is a constraint because of inadequacy of water, fluoride content in water which affects concrete characteristics and where structures cannot be accessed for curing. Poly Ethylene Glycol (PEG), Poly vinyl Alcohol (PVA), paraffin wax, acrylic acid is some of the commonly available hydrophilic materials in market. As aggregate represents about 70-80% of concrete components so it will be beneficial to recycle the aggregate for construction works and also to solve the environmental problems. To minimise the problem of excessof waste material it is a good step to utilize the recycled aggregates provide that the desired final product will meet the standards. Current practice assesses the quality of concrete based Primarily on strength. It has been suggested that the quality of concrete should be characterized not only by strength but also its durability characteristics. In the present investigation the individual effect of curing agents like PEG 600 ana PVA on strength and durability properties of concrete with varying dosages of 0.5%, 1%, 2% was investigated for M30 grade of concrete using recycled aggregate. Compressive strength, flexural strength, tensile strength and sorptivity, acid attack and permeability were evaluated to determine the strength and durability properties of hardened concrete. It was found that PEG600 and PVA could help in gaining the strength of conventional curing. The results indicate that PEG600 of dosage of 2% and PVA of dosage of 1% was optimum by giving strength on par with conventional concrete. The results indicate that self-curing concrete performs similar to the conventional concrete in all aspects of durability.

 Abstract

Filtering is the significant criteria to keep up power quality improvement in the three stage three wire framework.Presently active power filters are generally preferable for this reason.Taditional PI control techniques are disadvantageous in killing higher harmonics, created by the second harmonics at the DC link of a shunt APF. This paper proposes PR control strategy which invalidates second harmonics and provides better execution exactness contrasted with the conventional positive succession control technique and DC link voltage control technique separately regarding quality improvement and cost adequacy.
