  • Without real-time intelligence about operational performance, network status, and customer demand, water utilities face the challenge of reacting swiftly to any change in these conditions. Water utilities also experience the challenge of deteriorating water quality due to aging distribution piping and depleting water sources.

  • Mekong River, the 11th largest river in the world, is the main water source for irrigation, fishery, and domestic use… In short, the living of the whole population in the Mekong Delta (MD) is depending and will be depended on this resource. The MD of Vietnam is located at the most downstream part of the Mekong river basin. With a population of 17 million inhabitants living in 4 million hectares of land, the MD has great potentials for agricultural production. The MD is the most important agricultural production region for the whole country.

  • Water quality is one of the key factors affecting the environmental health of the Mekong river system. As the livelihoods of most of the 60 million people who live in the Lower Mekong Basin (LMB) wholly or partly depend on aquatic resources, the environmental health of the river is a major concern to the governments of the countries in the basin. In 1985, the Mekong River Commission (MRC) established the Water Quality Monitoring Network (WQMN) to provide an ongoing record of the water quality of the river, its major tributaries, and the Mekong Delta.

  • Research over the past decade has demonstrated the feasibility of extracting topographic information of hydrological interest directly from digital elevation models (DEM). Techniques are available for extracting slope properties, catchment areas, drainage divides, channel networks and other data (Jenson and Domingue, 1988; Mark, 1988; Moore et al., 1991; Martz and Garbrecht, 1992). These techniques are faster and provide more precise and reproducible measurements than traditional manual techniques applied to topographic maps (Tribe, 1991)....

  • The water problems in Asia’s cities are similar. These include sources and uses of raw water, the large propor-tion of water loss in distribution networks, intermittent supply, and the quality of tap water. In some cities, the excessive use of groundwater resources has caused serious environmental problems, including rapid deple-tion of groundwater, deterioration of water quality, and land subsidence.

  • The VMware vCloud Director abstraction allows a service provider to delegate vApp creation, management, and use to tenant Organizations (or an IT department to delegate these capabilities to line of business teams). While providing these capabilities, the Organization administrators and users do not operate on or manage vCenter or vSphere’s capabilities, like VMware vMotion™. Tenants deal only with deploying vApps to resource pools, datastores, and networks created for and assigned to that Organization.

  • Another use of mobility comes about if the specific area of interest (within a larger area) is unknown during deployment. For example, if a network is deployed to monitor the migration of a herd of animals, the herd’s exact path through an area will be unknown beforehand. But as the herd moves, the sensors could converge on it to get the maximum amount of data. In addition, the sensors could move such that they also maintain complete coverage of their environment while reacting to the events in that environment.

  • The Process Control settings allow you to enable additional Outpost security technologies such as Component Control, Hidden Process Control and Open Process Control. This protection is disabled by default, but if you consider your users experienced enough to manage the enormous number of network access request messages, you can enable it. Component Control monitors the components of each application to make sure they are not fake or malicious. You can set the desired Component Control level using the corresponding drop- down list. ...

  • Appendix B describes the current connectivity assumptions of commonly deployed grid software used in LCG. The LCG Security Group considers these assumptions to be inappropriate for deploying a production grid and recommends that developers and designers develop ways to more effectively constrain the required access of future systems. Specifically, whilst application developers MUST NOT rely on the availability of any connectivity not specified in this document, that described in Appendix B should also NOT be read as an agreed minimal set.

  • Questions have been raised about the social impact of widespread use of social networking sites (SNS) like Facebook, LinkedIn, MySpace, and Twitter. Do these technologies isolate people and truncate their relationships? Or are there benefits associated with being connected to others in this way? The Pew Research Center’s Internet & American Life Project decided to examine SNS in a survey that explored people’s overall social networks and how use of these technologies is related to trust, tolerance, social support, and community and political engagement.

  • Most people are aware of and concerned with the health effects of pesticide residues in the water they drink and the food they eat, but many are surprised to learn that pesticides are commonly found in air and rain. Scientific studies of pesticides in various atmospheric matrices (air, rain, snow, aerosols, and fog) have been ongoing for 40 years. When taken together, these studies, many of which are small and focused, provide a significant contribution to answering the questions when, where, how, and why pesticides are in the atmosphere.

  • PLANT CELLS, UNLIKE ANIMAL CELLS, are surrounded by a relatively thin but mechanically strong cell wall. This wall consists of a complex mixture of polysaccharides and other polymers that are secreted by the cell and are assembled into an organized network linked together by both covalent and noncovalent bonds. Plant cell walls also contain structural proteins, enzymes, phenolic polymers, and other materials that modify the wall’s physical and chemical characteristics.

  • Producers are also avid users of social media. Historically, producers have networked within a defined geographic territory. Because people generally only buy from producers they trust, developing trust has generally meant face-to-face interaction. However, as people grow more accustomed to trusting relationships developed online, producers who excel at developing such relationships will likely pursue licenses and sales opportunities outside traditional geographic areas.

  • Young women exposed to pregnancy experience greater likelihood of childbirth- related morbidity and mortality, with some countries experiencing mortality rates among women aged 15 - 19 that are as high as twice that of women in their 20s or 30s (WHO, 1989). Physiological under-development increases the likelihood of prolonged or obstructed labor, which may lead to ruptured uterus and death for the mother or fetus (Network, 1994). Negative pregnancy outcomes also result in part from poor prenatal health behavior among young adults, particularly teenage schoolgirls.

  • The narrative behind Simplified Ecosystem Capital Accounts (SECA): Ecosystems can be described as capital which delivers a bundle of services to people, some of which are appropriated and incorporated into products, accumulated and/or consumed. Other services are public goods of common benefit to the economy and human wellbeing. Altogether, these ecosystem services depend on ecosystem capital regeneration which is in turn influenced by ecosystem services consumption.
