 Abstract

Voltage sag is one of the primary concerns in power quality disturbance, even though there are several ways to characterize voltage sag, two basic characteristics i.e. sag magnitude and sag duration are the two most commonly used. Electromagnetic torque generated by an induction motor is directly proportional to the square of the voltage. Due to the wide use and popularity of induction motors, this paper investigates the effect of voltage sag duration, on the performance of induction motors under different voltage sags at various points of sag initiation. MATLAB Simulink environment is used for simulations of induction motors under various voltage types of sags of magnitudes (0.2 pu, 0.5 pu, and 0.8 pu) and duration 10 cycles (instantaneous sag) or sag of duration 1 sec (momentary sag) is performed. The results of the simulations have been compared based on torque peaks and current peaks. It has been found that the torque peak for an instantaneous sag is similar to the torque peak for a momentary sag for each type of voltage sag. Whereas current peaks were affected by the sag duration it has been found for momentary voltage sag of Type A, Type C, and Type D the magnitude of the current peak increases in comparison to instantaneous voltage sag.

 Abstract

This parking management system solves the matter of unnecessary time consumption in finding parking spots in parking areas. Sensors like IR (infrared) are used in order to detect the entrance or exit of the car at the parking slot and also detect the empty slot. This system clearly displays the total parking slots available and indicates the occupied slots and unoccupied slots on LCD display so that users can check the slots before entering the parking area and can park their vehicle in that slot within no time without wasting their time. The parking slots are continuously monitored and therefore the data is continuously updated on LCD display. The demonstration has proven the capability of the system to eliminate the effort of searching empty parking lots.

 Abstract

LIQUIDITY is regarded as one of the most important desired goals of an organization. Cement industry is not an exemption from this. The significance of adequate liquidity in the sense refers the ability of an enterprise to cater to the current/short term obligations when they become due for payment can hardly be over-stressed. In fact, liquidity is a pre-requisite for the very survival of an enterprise. The short-term creditors of the firm are interested in the short-term solvency or liquidity of a firm. But liquidity implies from the view point of utilization of the funds of the firm that funds are idle or they earn very little. A proper balance between the two contradictory requirements, i.e., liquidity and profitability, is required for efficient management of working capital. It is in this perspective; the present study is undertaken to examine and evaluate the liquidity management of select cement companies of Andhra Pradesh.

 Abstract

The objective of this research is to use the mixed solvency concept to create an enumerable number of eutectic mixtures. We can replace hazardous organic solvents with eutectic mixtures. Physical and chemical properties influence the solubility of solutes. As per Maheshwari's mixed solvency concept, everything in the universe has the ability to dissolve each and everything, whether it is a gas, a liquid, or a solid. The concept of a eutectic mixture is "an isothermal, reversible reaction between two (or more) solid phases during the heating of a system, leading to the formation of a single liquid phase." To prepare for this study, we used a number of solutes and solvents.

Avinuo Kire is a writer from Nagaland, a state in North-east, India. She lives in Kohima, Nagaland and teaches English at Kohima College, Kohima. She has written an anthology of short stories, The power to forgive: And Other stories, a collection of poetry, Where Wild Flowers Grow, co-authored a collection of oral narratives, Naga Heritage Centre: People Stories. In her book titled, The last Light of Glory Days: Stories from Nagaland , Avinuo talks about the history of the land full of conflict, untold sufferings of the people interlaced with myths and supernatural beings. It is so deeply rooted in tradition and community culture of her people. Naga people do not have a written record so folklores and myths are the repository of their origin and history. She has delved into the myths not only to preserve the uniqueness of her land but has also depicted and portrayed how the myths and traditional beliefs steep in supernatural are still rooted in the modern Naga society.

 Abstract

Multi-particulate drug delivery systems are utmost accepted and widely used dosage form as they offer so many benefits over unit dosage form like improved bio-availability because of increased surface area, reduced inter-subject variation and reduced chances of dose dumping. Pelletization is one of the most promising techniques for the multi-particulate drug delivery system. The purpose of this study to apply the QbD approach to optimize the formulation of a dual release pellets containing Losartan potassium prepared by extrusion and spheronization. A 32 full factorial design is the simple experimental design with two variables studied at three levels. In the present study, the type of polymers used HPMC (X1) and percent polymer replaced with MCC (X2) to achieve Sustained release of Losartan potassium taken as independent formulations variables. The Critical quality attributes (CQA) to be applied for formulation development is the response factors, such as the dissolution profiles at 2nd hr and 8th hr to be taken as dependent response variables. The optimized formulation to be characterized by comparison with the various physical properties and in-vitro pharmacokinetic parameters.

 Abstract

Due to its natural nature, fewer side effects, and discontent with the outcomes of synthetic pharmaceuticals, traditional herbal therapy and its preparations have been utilised extensively in both industrialised and developing nations for thousands of years. To the contrary, one of the traitsthe decoction procedure, all the herbal remedies, whether they are presented as single herbs or as groups of herbs in composite formulations, are extracted with boiling water. It's possible that this is the key factor behind why it's harder to monitor the quality of eastern herbal medicines than it is for western ones. According to the "General Guidelines for Methodologies on Research and Evaluation of Traditional Medicines" (World Health Organization, 2000), Inadequate or unaccepted research methodologies for evaluating traditional medicine are the main causes of the lack of research data, in addition to health care policy (WHO, 2000, 2001). In the past, vaidas treated patients on an individual basis and prepared medications based on their needs, but today the situation has changed, and are produced on a large scale, and manufacturers face a variety of challenges, including the need for good quality raw materials, the authentication of raw materials, the availability of standards, the need for proper standardization methodologies for individual drugs and formulations, the need for quality control parameters, etc.
