  • Earth science is an all-embracing term for the sciences related to the planet Earth.[2] It is arguably a special case in planetary science, the Earth being the only known life-bearing planet. There are both reductionist and holistic approaches to Earth sciences. The formal discipline of Earth sciences may include the study of the atmosphere, hydrosphere, oceans and biosphere, as well as the solid earth.

  • Earth as an Evolving Planetary System presents the key topics and questions relating to the evolution of the Earth's crust and mantle over the last four billion years. It examines the role of plate tectonics in the geological past via geological evidence and proposed plate reconstruction. Kent Condie synthesizes data from the fields of oceanography, geophysics, planetology, and geochemistry to examine the key topics and questions relating to the evolution of the Earth's crust and mantle.

  • This chapter reviews some of the basic magnitudes of solar radiation and some of the basics of PSpice. A brief description of a photovoltaic system is followed by definitions of spectral irradiance, irradiance and solar radiation. Basic commands and syntax of the sentences most commonly used in this book are shortly summarized and used to write PSpice files for the AM1 SG and AM0 sun spectra, which are used to plot the values of the spectral irradiance as a function of the wavelength and compare them with a black body radiation.

  • Weather natural hazards, the environment and climate change are of concern to all of us. Especially, it is essential to understand how human activities might impact the nature. Hence, monitoring, research, and forecasting is of the outmost importance. Furthermore, climate change and pollution of the environment do not obey national borders; so, international collaboration on these issues is indeed extremely important.

  • Today, space technology is used as an excellent instrument for Earth observation applications. Data is collected using satellites and other available platforms for remote sensing. Remote sensing data collection detects a wide range of electromagnetic energy which is emitting, transmitting, or reflecting from the Earth's surface. Appropriate detection systems are needed to implement further data processing. Space technology has been found to be a successful application for studying climate change, as current and past data can be dynamically compared.

  • One of the biggest prob1ems of Vietnam's property market is it's low level of transparency. An indication of this problem is that people usually are unable to obtain 1and information as they need due to both technical and organisational limitations. To partially resolve this problem, the authors have proposed a technical solution by designing a simple, 1ow-cost system based on open source WebGIS technology for delivering land information to people anywhere and anytime.

  • The system of three-dimensional hydrodynamic-environmental models could simulate full advection and dispersion processes of the dissolved and particulate matter as suspended sediment and all oil phases in the realistic marine conditions. The hydrodynamic model provides temperature, salinity and current structure and water level. These variables will be used in the environmental model simulating the advection and diffusion processes for suspended matter concentration, bottom sediment thickness and all oil spill phases in the water and bottom sediment.

  • Public transport is a part of the contemporary urban model. In Vietnam, the bus system is re-established a few years ago. At the same time, some maps have been published for helping the bus passengers. But these maps are still lacked of rich contents and useful functionalities. With the aim to improving the effectiveness of Hanoi public transport system, the authors have applied GIS technology for developing an information system of Hanoi bus. A logical model of the bus network consisting of 2 sub-networks and 5 cost attributes has been designed. This model serves as a basis for developing...

  • J upiter is by far the biggest planet in the solar system. It is a vast planet of swirling gases and storms of unimaginable fury. As the fifth planet out, it is the nearest gas giant, a planet made almost completely of gases, to the Sun. It is not much smaller than some of the stars called brown dwarfs. Jupiter does not shine itself, but reflects sunlight as all planets do. Even so, its huge pull of gravity holds more than 60 moons in orbit around it. Jupiter is named after the Roman king of the gods, also called Jove....

  • We live in an era with unparalleled opportunities to practice disease prevention based on knowledge of the earth environment. Although globally distributed early warning systems can monitor physical hazards such as earthquakes and tsunamis, chemical hazards on the other hand—whether actual or potential and natural or anthropogenically induced—remain difficult to accurately identify in time and space. Such hazards often have lengthy asymptomatic latency periods before disability or disease becomes evident....

  • New specialties sometimes combine with the traditional fields and form new branches - for example Earth Systems Engineering and Management involves a wide range of subject areas including anthropology, engineering, environmental science, ethics and philosophy. A new or emerging area of application will commonly be defined temporarily as a permutation or subset of existing disciplines; there is often gray area as to when a given sub-field becomes large and/or prominent enough to warrant classification as a new "branch.

  • Since the time of Newton the basic structure of the solar system and the laws that govern the motions of the bodies within it have been well understood. One central body, the Sun, containing most of the mass of the system has a family of attendant planets in more-or-less circular orbits about it. In their turn some of the planets have accompanying satellites, including the Earth with its single satellite, the Moon. With improvements in telescope technology, and more recently through space research, knowledge of the solar system has grown apace.

  • In this paper, the authors apply the HPI index of UNDP 1995 to clarify the poverty levels of the poor living in six environmental poverty sectors according to ADB, 2008, in order to form a new Environmental Poverty Index (EPI) of national and provincial levels prospectively. This index is easy to communicate worldwide. To clarify the poverty levels of the environmental poverty in environmental sectors, a set of six environmental poor livelihood indicators (EPLI) is also proposed.
