Remote sensing and GIS in disasters management-in special reference to Asian countries

During the past five decades, natural hazards such as floods, earthquakes, severe storms and tropical cyclones, droughts, wild land fires, and also manmade disasters such as Nuclear disaster, oil spills, and terrorist attacks have caused major loss of human lives and livelihoods, the destruction of economic and social infrastructure, as well as environmental damages. Disaster reduction is both an issue for consideration in sustainable development agenda and a cross cutting issue relating to social, economic, environmental and humanitarian sectors. These important features have to analyze and there is a need to study. Though, in recent years the Open GIS technology standards have been developed by several agencies, which provide the basis for utilization of geographic information services, also gives an opportunity for data interoperability, data integration and data sharing between different emergency management agencies, However finding suitable services and visualization of geospatial information for decision makers is still a crucial task. Objective of this paper is to assess the state of art literature review in different methodologies of utilizing geospatial technology in managing both natural and manmade disasters dedicated by different authors and also to find new direction in this important area

Effect of global warming on monsoon:With reference to Chhattisgarh State

Global warming is increasing the average temperatures of the earth. A rise in earth’s temperatures can in turn root to other alternation of ecology including sea level and modifying the quantities and patterns of rain fall. This modification may boost the occurrence and concentration of severe climate events such as floods famines, heat waves tornados and twisters. Scientists all over the world are making prediction about the ill effect of global warming and connecting some of the events that have taken place in the Past few decades as an alarm of global warming. The Intergovernmental panel on climate change (IPCC) conclusion that increasing greenhouse gases concentration resulting from human activities such as fossils fuel burning and deforestation are responsible for most of the observed temperature increase since the middle of 20th century. As of June 2012, only the United State historically the world’s largest emitter of green house gases which is main cause of global warming has refused to rectify the KYOTO protocol treaty. In Chhattisgarh state gradual decrease in rain fall has been seen since last 50 years due to global warming. During the last 5 decades the average rainfall in Chhattisgarh state has fallen down from 1301 millimeter to 1150 millimeter .In Chhattisgarh state the arrival of monsoon every year has been noted the 2nd week of June and this year monsoon arrived on 5th June, 2012, this monsoon word is derived from Arabic word mousim. Recently the scientists have prepared a Visual ALTAS to know where the rain falls have occurred. This visual atlas has been prepared by international team led by National University of Australia

PHYTOCHEMICAL PROFILING AND EFFICACY EVALUATION OF ANTIBACTERIAL POTENTIAL OF MYRISTICA FRAAGRANS SEED EXTRACTS AGAINST SELECTED MICROORGANISMS

Introduction: Traditional plants have been proved as novel source for health care remedies. Plants are the rich source of bioactive compounds which can be useful for health care purpose. Emergence of resistance among pathogenic bacteria against available antibiotics is a common phenomenon. So the plant based bioactive molecule may be an alternative for the development of new formulation. The use of natural bioactive molecules as parental compound for development of new formulation may be safer with less side effects as compared to synthetic chemical compounds. Myristica fraagrans seed are widely used in routine life from ancient time for health care. Traditionally it is being used in for stomach related complications. So the current study pertained to the phytochemical profiling of Myristica fraagrans seed and its efficacy evaluation against some clinically significant bacterial species.Methods:  In this study ethanol and acetone extract of Myristica fraagrans seed (Jaiphal) were prepared via using soxhlet apparatus. Extract were qualitatively analysed to check the phytochemical composition. Then antibacterial efficacy of prepared extracts were analysed by agar well diffusion assay against Escherichia coli, Bacillus subtilis, Bacillus Magetarium, Proteus mirabilis.Results: The result of phytochemical profiling shows the presence of tannin, terpenoids, alkaloids, indole and phenol. Moreover Myristica fraagrans seed extract exhibiting significant antibacterial activity against selected microorganisms.Conclusion: Finding of the study concludes that Myristica fragrans seed ( jiphal )  possess the antimicrobial capabilities against infections and/or diseases caused by chosen microorganisms and seems to be useful in the discovery of novel antibiotic drugs. KEY WORDS: Myristica fraagrans (Jaiphal), Escherichia coli., Bacillus subtilis, Bacillus Magetarium, Proteus mirabilis., antibacterial activity etc.Â

An analysis of some major antennas’ using frequency 750 MHz to 850 MHz

An antenna is transducer, an impedance matching device, a radiator and a sensor of electromagnetic waves. It is essential device/element in all types of communication and radar systems. It can be considered as a source of electromagnetic wave. In this research paper an attempt has been made to study the characteristics of major antenna using frequency from 750MHz to 850MHz. In this experiment as well as research ATS-B Antenna system trainer is utilized. An antenna (or aerial) is an electrical device which converts electric power into radio waves, and vice versa. It is usually used with a radio transmitter or radio receivers. In transmission, a radio transmitter supplies an oscillating radio frequency electric current to the antenna’s terminals, and the antenna radiates the energy from the current as electromagnetic waves(radio waves). In receptions , an antenna intercepts some of the power of an electromagnetic wave in order to produce a tiny voltage as its terminals, that is applied to a receiver to be amplified. Typically an antenna consists of an arrangement of metallic conductors (elements), electrically connected to the receiver or transmitter. As oscillating current of electrons forced through the antenna by a transmitter will create an oscillating magnetic field around the antenna elements, while the change of the electrons also creates an oscillating electric field along the elements. Antenna can be broadly classified by the directions in which they radiate or receive electromagnetic radiation. They can be isotropic ,omni-directional or directional. An antenna is chosen for a particular application according to its main physical and electrical characteristics. Further an antenna must perform in a desired manner for the particular application. An antenna can be characterized by the following key factors , not all are applicable  to all types of antenna. Main characteristics of an antenna are : radiation resistance, radiation pattern, the bandwidth etc. Further it has been found that graph of antenna polar plot which describes about antenna characteristics. Antenna are essential  components of all equipment that uses radio. They are used in systems such as radio broadcasting, broadcast television, two-way radio, communication receivers, radar, cell phones, and satellite communication, as well as  other devices such as garage door openers, wireless microphones, Bluetooth enabled devices, wireless computer networks, baby monitors, and RFID tags on merchandise. This paper introduces antenna theory and discusses various antenna types and applications. The basic equations and principles of antenna theory are presented. Five different types of antennas are introduced: dipoles and monopoles, loop antennas, microstrip antennas, helical antennas, and horn antennas.The characteristics of each type of antenna are given.&nbsp
