Nigeria (total land area of 923,768 km2 ) is underlain by a crystalline Precambrian basement, Jurassic granites, and Cretaceous to Recent sedimentary rocks, and is prone in places to environmental degradation and geohazards. The country hosts approximately 34 different mineral types in about 855 locations with considerable oil and gas reserves.…

This paper gives a brief analysis on the educational advantages and objects of NCWU. It believes that the educational philosophy and development direction of foreign school in engineering colleges must be set up on the basis of need of China and talents need, moreover, the development of the School of Foreign Studies must be analyzed by…

This paper analyses poverty reduction in Bhutan between two points in time--2003 and 2007--from a multidimensional perspective. The measures estimated include consumption expenditure as well as other indicators which are directly (when possible) or indirectly associated to valuable functionings, namely, health, education, access to electricity,…

This report is part of a series of reports that provides information on the structure, function, finances, taxation, employment, and pension systems of the United States' approximately 90,000 state and local governments. This report presents data on state and local government employment and payroll based on information collected by the 2013 Annual…

This dissertation is a combination of two research areas, experimental physical chemistry, Chapters I to V, and chemical education, Chapters VI to VII. Chapters I to V describe research on the water-mediated chemistry of oxidized atmospheric molecules and the impact that water has on the spectra of these environmental systems. The role of water…

Students learn science best with activities that mirror the way scientists work. This article describes how geologists investigate groundwater flow systems in areas of karst topography--geologic formations shaped by dissolving bedrock--and provides a way for students to replicate this research. Students also use electric current to model water…

"Element Cycles" is an activity designed to reinforce correlation of essential elements and their different forms in the ecosystem. Students are assigned essential elements to research as homework, then share results, and construct game boards with four ecosphere sections: geosphere (earth), hydrosphere (water), atmosphere (air), and biosphere…

The United Nations (UN) mandate of achieving healthful living for all by the year 2015 through the Millennium Development Goals (MDGs) is facing several challenges. In the school environment, and particularly in less developed countries (LDCs), the situation is further strained by both relatively weak infrastructure and competing governmental…

Being able to dive and breathe underwater has been a challenge for thousands of years. In 1980, Fuji Systems of Tokyo developed a series of prototype gills for divers as a way of demonstrating just how good its membranes are. Even though gill technology has not yet reached the point where recipients can efficiently use implants to dive underwater,…

Because school business officials are pushed to make difficult decisions quickly when it comes to risk management, they should be aware of the issues associated with environmental safety. School business officials are integral members of the teams that handle crises--big and small--in the school district. A crisis may be as straightforward as the…

In November 2009, the largest experiment in history was restarted. Its prime target is the Higgs particle--the last remaining undiscovered piece of our current theory of matter. We present a very simple way to introduce this topic to senior secondary school students, using a comparison with the refractive index of light.

The authors observed preschoolers engaged at the sand and water table to determine if math could be found within their play. Wanting to understand how children interact with provided materials and what kinds of math ideas they explore during these interactions, the authors offer practical examples of how such play can promote mathematical…

The 2010 "Deepwater Horizon" oil spill greatly affected the Gulf Coast, and the news media reported information to wide audiences. Students enrolled in an online Environmental Geoscience course in fall 2010 voluntarily participated in a Gulf oil spill survey. More than 92% of the students (N = 77; 83 total enrollment), who were primarily…

The main aim of this study was to examine how a group of elementary students perceived their engagement in a project-based science intervention investigating the water quality of a local lake. The students collaborated with a scientist to conduct various experiments and used handheld computers to collect and analyze data in order to examine the…

Due to the inappropriate planning and explosive population growth in urban areas, especially in developing countries, sustainable and disaster-safe urbanization has become the most important challenge for governments. Urbanization presents benefits in different ways but has led simultaneously to changes in land use/land cover (LULC), impacting…
