To understand the biological importance of sodium pyrophosphate and its applicability as inhibitors in urolithiasis disease, we have studied the inhibition efficiency of sodium pyrophosphate towards the mineralization of urinary stone forming minerals like calcium phosphate, in aqueous as well as urinary medium. An attempt has been made to unfold, tentatively, the mechanism of inhibition by this inhibitor. It was Observational experiment. The Study was Conducted in the chemistry lab of university department of chemistry, B N Mandal University, Madhepura (Bihar) An experimental model was designed by taking the salt forming solutions, the whole operation took about 40-50 min. At the end the contents of beaker were digested in a hot water bath, cooled to room temperature and centrifuged in small volumes. The total centrifugate was collected and Calcium and carbonate content of the centrifugate of calcium carbonate mineralization experiments were determined. Sodium pyrophosphate has a moderate inhibition efficiency towards calcium carbonate mineralization. At 0.05 M concentration, sodium pyrophosphate has a net inhibition of 30 % which is 26.65 % more than that of water (blank). Compared to water the percentage inhibition increased by 795.52%. With decreasing concentrations of sodium pyrophosphate, the inhibition efficiency decreases. At very low concentration (0.01 M) its inhibition is only slightly higher than that of water. In urinary medium sodium pyrophosphate seems to function as a better inhibitor of phosphate mineralization. At 0.05 M concentration, sodium pyrophosphate has a net inhibition of 89.22 % which is 75.36 % more than that of urine.  It is observed that sodium pyrophosphate solution, under different concentrations, exhibits moderate to good efficiency of inhibition towards mineralization of urinary stone forming minerals like calcium carbonate in aqueous as well as urinary medium.

Usually, most of the AUV has the propeller and it is placed in a suitable position for maneuvering in the required direction. For single propeller AUVs, propeller is placed at the aft, and direction is controlled using wings that are placed aft. Energy is a major part of an underwater operation to decide the duration of underwater operation. To increase the duration of the battery, either the energy consumption can be reduced or the efficiency of the propulsion system needs to be improved. Here the possible opportunities to improve the propulsion system using hydrodynamic energy devices are discussed. Though many options are available, based on space availability & speed, a suitable combination of devices can be added. It is recommended to carry out CFD analysis to make sure that proposed devices can bring improvement in the propulsion system before it is implemented.

Cooling of miniaturized spaces like electronic components is a major challenge to heat transfer engineers. Miniaturization of systems is an advantage and there has been a recent flourish of Micro Electro Mechanical Systems (MEMS). Hence, there is an obvious increase in demand for cooling of micro-devices and implementation of micro-channels is one of the most efficient ways for cooling applications in micro systems. The present paper discusses the applications of micro-channels, nature of flow in micro-channels, suitable materials which includes the recent developments in micro-channel material selection, fabrication aspects used for making micro-channels and the limitations which hinders a fully successful implementation of micro-channels. The use of fins and special materials recently introduced by the industry is also discussed.

The present work reinforces material for polymer composites alternative to the use of Epoxy resin LY556, Glass – Woven and Chopped. The hybrid composite material   is a combination of two or more different types of fiber in which one types of fiber balance the deficiency of other filler. Iron powders are used as a filler material. The composite laminates were fabricated by varying weight percentage of 0, 1, 3, & 5 of Filler material using hand layup technique. The mechanical properties of the prepared composites materials were characterized in terms of tensile strength and impact (Izod) tests as per ASTM standards. At addition of 3 wt. % of iron powder the tensile strength was improved by 44% and impact strength by 94.2% when compared with neat polymer composites. The reason for the enhancement was wonderful interfacial bonding with fiber and polymer matrix.

Many health care assists had been developed to help the clinicians in treating the patient. A single monitor for managing an instrument seems very expensive. The transferring of data from the single setup also requires high communication costs. The personal assistant developed has many drawbacks due to the changes in prosodic cues according to the people’s language slang and the trouble in analysing the paralinguistic information. The network data and energy consumption required for the transfer of information from the health care devices becomes quite large. The project, involves an easy transmission module and assisting method to avoid these issues. This project is involved in assisting a practitioner, physician or respiratory therapists in proper handling of a ventilator, in accordance with patient’s health state and parameter. On providing ventilation, it is important to notice the ventilator readings such as i-PEEP, Ppeak, Pplat (developed values in the patient’s respiratory system) which are the response of the patient etc.,. On observation of these readings, the parameters such as e-PEEP, VT, RR and FiO2 (values to be set by the clinician) have to be adjusted for better ventilation and for the purpose of weaning of patient in a short period. The preliminary work involved is the data acquisition and logging. The SVM algorithm has been developed with many data points as the parameters obtained from data. The protruding idea is to analyse the patient’s age, gender, weight, disorder, type of surgery and its duration. Thus, the value of the parameter that has to be adjusted can be determined intricately with the protruding idea of digital assist.

Electrical revelation of neuromuscular information transmission generated in muscles contraction and relaxation is known as EMG signals. Electromyography (EMG) is real-time based method to assess and observe a series of electrical signals that expressed from body muscular cells. In recent researchers had provided many systems for monitoring myoelectric signals (EMG) to identify various abnormalities such as EMG, Microcontroller sensors technology, EMG software signal processor (SPU), PWM method, capacitive sensing method, UML method, EIM method, ADU integration, MC sensors method, Human computer interfacing (HCI) technology and Functional electrical stimulation (FES). This paper proposes a system to implement a wireless transformation technology for monitoring the electrical potential from muscles to identify internal injuries, blood clots, muscle cramps, muscle fatigue, muscle contraction, limb stiffness, and immobility. In this paper, electrical signals acquired from the muscles are detected using EMG sensors. These occurring signals transmitted by using wireless method and processed by using MAT Lab tool. This technique makes our system more unique from the previous methodologies. Finally accurate EMG signals are displayed graphically. Thus the expected configuration result will be with an accuracy of 98.74%, mean specificity of 99% and with a mean sensitivity of 96.58%.So the error occurrence will be Approximately 0.5% and also system is low cost, electrical safety, low power consumption, and can identify muscle disorders through observed abnormal EMGrange.
