Detection of Anomalies in the Quality of Electricity Supply

From the last two decades, power quality is getting much attention. Proper functioning of the equipment depends upon the quality of power supplied. Every year, demand of electric power goes on increasing and the power system network is expanding and becoming more complex. On account of thrust on clean power supply, use of renewable sources has dramatically increased in grid but it simultaneously causes power quality problems. In this work, power quality disturbance detection in wind farm integrated with grid is presented. For disturbance detection, time-time transform has been employed. The disturbance signal for the detection purpose is generated in MATLAB/Simulink environment by using a Simulink model

Modelling for Improved Cyber Security in Smart Distribution System

Information technology is the backbone of the smart grid, where all networks like generation, transmission, distribution, and customer components are connected to each other. Connectivity between these components offers many advantages including consumer�s ability to manage their electricity consumption rates and electricity bills etc. Smart grid also provides operators great extent of system visibility and control over electricity services, supervision and control of generating units, power quality improvements and reduced fuel cost etc. Highly connected infrastructure in smart grid threats the reliable operation of grid, especially in terms of cyber security. In automated system, where control actions can be generated by a single command even from a great distance may lead complete shutdown of the whole system. Failure/disoperation of power service suspends all critical services. Therefore, the electrical grid becomes the most significant target for acts of vandalism and terrorism. So an extensive security against the cyber-attacks is required in smart grid environment as compare to traditional electricity grid, where almost all control actions were taken manually or with little use of local controllers. Therefore, with control atomization modulation of traditional energy supply system into a smart network requires a huge investment to develop security strategies as a safeguard for this critical infrastructure

Frequency Management Strategies for Local Power Generation Network

This paper presents an intelligent load frequency control technique based on ANFIS controller which is capable to restore system frequency within small fraction of time. Frequency deviations in microgrid occur when the system supply is not sufficient to match the demand. Efforts are required to keep the frequency deviation within acceptable limit. Using vehicle-to-grid technology, where electric vehicles are used as energy storage elements for load frequency control in microgrid. For generating the control action to electric vehicles and energy sources in microgrid, type-2 ANFIS has been employed for quick frequency stabilization in the presence of load and source disturbances. Diesel generator and wind generator are DG sources considered in this paper and electric vehicles are used as energy storage element. Optimal power sharing among the different generating units and electric vehicles is achieved by ANFIS controller. Adaptive nature of ANFIS makes it more suitable and highly robust controller for a complex inter-connected system. Simulation results demonstrate that ANFIS controller is highly efficient as compared to PID controller, fuzzy logic controller, and interval type-2 fuzzy logic controller

ANATOMICAL STUDIES ON CORBICHONIA DECUMBENS (FORSSK.) EXELL, AN IMPORTANT MEDICINAL HERB FROM RAJASTHAN

Corbichonia decumbens (Forssk.) Exell, commonly known as pater-chatti, is an annual or short lived perennial herb found in rocky habitats. It is used to cure kidney stone and gonorrhoea. The main objective of this study was to examine the anatomical characters of whole plant of C. decumbens for identification. The transverse sections of root, stem, leaf and flower have been examined and analysed. Photomicrographs were prepared with Sony HD (1920x1080/50i) digital camera. The microscopical studies revealed several interesting features viz., the presence of anomocytic stomata on both the surface; more on adaxial surface starch grains present in cortical region of root, rosette crystals in almost all vegetative parts that some time forms clusters, sclerenchymatous pericyle in stem and root presence of wide medullary rays in secondary xylem and bundle sheath around vascular bundles. The outcome showed many unique characters which may prove most important in taxonomical relevance. This study would be useful for correct identification and authentication of the plant. Keywords: Anomocytic, Dorsiventral, Medullary rays, Bundle sheath, Rosette crystal

Assessment of Indian cooking practices and cookwares on nutritional security: A review

Food provides us nutrients and the energy required for growth, reproduction, and maintenance. Energy is required to perform all voluntary and involuntary activities like digestion, respiration, circulation, carrying out professional, household and recreational activities. Despite having rich food diversity, we are using only a few items as our staple food.  With the adoption of eastern cooking practices and cookwares, risk of both pre-and post-transitional diseases like diabetes, cardiovascular diseases, malnutrition, obesity, etc. has increased significantly. Aluminium toxicity and nutrients breakdown has become a common problem in pressure cooking. To overcome this problem, it is important to shift from the modernized cooking methods to our traditional cooking practices, i.e., use of earthen cookwares, clay pots and some selected metal utensils, e.g., copper, iron, brass, etc. It has been shown that earthen, copper, iron, and soapstone cookwares do not leach toxic trace elements into the food and enhance the sensory qualities without decreasing the food nutrients. Adoption of traditional Indian cooking practices (such as fermentation, roasting, germination, etc.), cookwares (such as earthen, copper, iron, soapstone, etc.) and increasing the consumption of healthy diet grains like millets, etc. can easily combat the pre- and post-transition health problems in India, effectively. This review would provide a deep understanding to the people to decide the best cookware and cooking processes that will improve their health and provide ample nutritional value to them

A comparative analysis of conventional smear and sure path liquid-based cytology with cell block preparation

Background: Cervical cancer is ranked as the most frequent cancer in women in India. Conventional papanicolaou smear has been the mainstay of cervical cancer screening since the 1960s. As an alternative liquid-based cytology (LBC) was introduced in the mid-1990s, which are found to increase cytologic detection of squamous intraepithelial lesions and a reduction in the number of unsatisfactory pap tests.Present study aims at comparison of liquid-based cytology with conventional cytology in detecting uterine cervical intraepithelial lesions.Methods: The present study was conducted in the department of pathology in collaboration with the department of obstetrics and gynecology, Pt. B.D. Sharma PGIMS Rohtak including 100 non-pregnant female patients coming in the outpatient department of obstetrics and gynecology. Both liquid based and conventional pap smears were examined under the microscope and reported according to the 2001 Bethesda system. Cell blocks were prepared sin all the cases from the residual material of LBC.Results: Median age was 42 years. More inadequate smears were reported on CS (17%) as compared to LBC (11%). In both, maximum number of cases reported were inflammatory. Equal number of cases were reported as SCC (n=4) in both.Conclusions: Liquid based cytology has been developed to address the sampling problems of conventional Pap smear. But because of the increased cost of LBC in terms of capital investment, operation and disposables, developing countries should carefully consider the potential benefits and drawbacks of LBC before adopting this new technology

CURATION AND MANAGEMENT OF CULTURAL HERITAGE THROUGH LIBRARIES

Libraries, museums and archives hold valuable collections in a variety of media, presenting a vast body of knowledge rooted in the history of human civilisation. These form the repository of the wisdom of great works by thinkers of past and the present. The holdings of these institutions are priceless heritage of the mankind as they preserve documents, ideas, and the oral and written records. To value the cultural heritage and to care for it as a treasure bequeathed to us by our ancestors is the major responsibility of libraries. The past records constitute a natural resource and are indispensable to the present generation as well as to the generations to come. Libraries preserve the documentary heritage resources for which they are primarily responsible. Any loss of such materials is simply irreplaceable. Therefore, preserving this intellectual, cultural heritage becomes not only the academic commitment but also the moral responsibility of the librarians/information scientists, who are in charge of these repositories.

Review on Floating Microsponges: An Updated

Floating microsponges are an approach to prolong gastric residence time, there by targeting site-specific drug release in the upper GIT for local orsystemic effect. Gastro retentive dosage forms (GRDFs) are being used from a very long time to improve therapy with several essential drugs.Floating microsponge greatly improves the therapy of stomach by releasing the drug locally and thus used for drug targeting at particular organ.This can be sustained over a longer duration of time. Floating drug delivery (FDDs)permit prolonged and continuous release of the drug to theupper part of Gastro intestinal tract (GIT) and this expressively extend the duration of drug release and improve bioavailability of drugs that havenarrow therapeutic window, by this technique dosing frequency and patient compliance is increased. The purpose of this paper is to brieflydescribe the floating microsponge drug delivery (FMDD), factors related to Floating Drug Delivery, its advantages disadvantages, and emphasisis given over its significance over conventional form of drug deliveries
