 Abstract

When the hazard occurs it may then be called an event, accident, emergency, incident, or disaster. The study and monitoring of geo-hazards helps us to better prepare ourselves and respond to these geological events when they do occur. Geo-hazards can be small features that have an impact only on their local area such as a small landslide that partially blocks a road or track through to large earthquakes that affect entire cities. They can also be very large events that have a widespread impact such as large tsunami. The paper describes, as Geo-hazards are geological and environmental conditions and involve long-term or short-term geological processes. Geo-hazards can be relatively small features, but they can also attain huge dimensions (e.g., submarine or surface landslide) and affect local and regional socio-economy to a large extent (e.g., tsunamis). The processes that have formed the earth continually act on or beneath its surface. The movement of plates in the earth's crust and local concentrations of heat are a continuing source of hazards to people and their structures. The results of the extensive research on geologic hazards that has been conducted to date have been translated into a form accessible to non-scientists, and small-scale maps displaying historic, actual, and potential hazard levels are available. The geologic hazard assessment techniques, most of which are well beyond the technical, temporal, and budgetary constraints of integrated development planning studies, it presents and discusses existing information which can and should be used during the Preliminary understanding. This information is sufficient to show, whether a hazard constitutes a significant problem in development area and, day to day life.

 Abstract

Abstract Cyanobacteria are also know as blue-green algae, invented oxygenic photosynthetic and were responsible for the oxygenation of the Earth�s atmosphere. Cyanobacteria require solar radiation as a sole energy source for the fixation of carbon and nitrogen. Therefore, they have great potential as biofertilizers.Cyanobacterial biofertilizers are inexpensive, simple to use and have no problem of environmental pollution. Symbionts such a cyanobacteria increase the efficiency of nutrient acquisition by plants. Cyanobacterial biofertilizers mobilize nutritionally important elements such as P from a non-usable to a usable form through biological processes. Cyanobacteria also involved in sustainable agriculture by the process of soil heavy metal bioremediation. This review is an effort to share the valuable information about of cyanobacteria as biofertilizer and their potential role in the agricultural and environmental for the future welfare of the society.

 Abstract

The present technology commonly used for cutting the grass by using the manually handle device. The project aims to fabricate a grass cutting machine system controlled by android application using Bluetooth module feature which runs with the help of motor by using solar energy. In previous days, grass cutter machines are operated by fuel and electrical energy which are costly and requires high maintenance. The solar panel is used to charge the battery so that there is no need of charging it externally. The solar based energy source is easier to use, more advantageous compared to other energy and it is easy to work[1]. By the use of solar panels we can harness sunlight to generate electricity free of cost. The trapped solar energy is used to charge the battery for grass cutting operation. The movement of the machine is totally controlled by automatic mode or manual mode. The Bluetooth controller run this machine movement and direction through an android application. The controlling device of the whole system is microcontroller. Bluetooth module and DC motors are interfaced to the microcontroller. The data received from the android phone application by Bluetooth module is fed as input to the controller and the controller acts according on the DC motor of the solar grass cutter. In achieving the task, the controller is loaded with a program written using Embedded �C� language.
