Biofuels: Potentials, Problems & Solutions

Biofuels have the exciting potential of mitigating the grave threats of global warming, reducing the world\u27s dependence on imported oil from insecure sources and of reducing the skyrocketing costs of oil that are threatening to undermine the world\u27s economies and devastating the people in non-oil producing, developing countries. For the people in these countries, biofuel offer a promising road to enhance development since they use local materials, can provide local jobs, and do not require the import of expensive equipment and expertise. Brazil has been the pioneer in the use of biofuel, allowing it to eliminate its oil imports, becoming completely energy independent, and demonstrating to the world the potential benefits of substitution of biofuels for fossil fuels. Indeed, inspired by Brazil\u27s example, the United States in recent years has developed a strong biofuel industry, albeit from the disadvantageous feedstock of corn. The United States has just created an alliance with Brazil to make major purchases of its biofuels. The European Union and countries around the world are rapidly developing their own biofuel potentials. But Brazil and its replicators have to exercise great care in designing and implementing biofuel programs. The environmental and social risks of biofuel development, also demonstrated in Brazil, are great and could well undermine all of the potential advantages if not done right

Qualitative and Quantitative Aquatic Algal Data Compilation to Determine Macrotrends

A data base of the algae of Arkansas has been initiated by the selection of a relational data base management system. The system was chosen to be readily available for microcomputers using MS- or PC-DOS. The initial parameters chosen for entry are associated with the classification of the organisms from Class to the Variety level with author and year of initiation. Further annotation includes identification source. Presently, the data base of 1,162 taxa includes 226 Cyanophyceae, 367 Chlorophyceae, 124 Euglenophyceae, 26 Xanthophyceae, 81 Chryso- phyceae, 279 Bacillariophyceae, 33 Pyrrhophyceae, 14 Cryptophyceae, and 5 Rhodophyceae. These taxa are sortable by any of the included parameters. The data base will be archived as a portion of the flora and fauna series of the state of Arkansas

Pedagogical inspiration through martial arts instruction

This article discusses how the martial arts studio can be used as a model for improved instruction for the classroom teacher. Four common teaching techniques, common to the martial arts classroom, are defined and described. They are (a) motivating by praise and recognition, (b) differentiating instruction, (c) using formative assessments, and (d) employing preventive discipline. Explanation and illustrations of how to generalize each technique for the academic classroom are also included
