An effective semi-continuous process was developed to grow a locally isolated green microalga Chlorella sp. on acidogenically digested swine wastewater in bench scale for improved algal biomass production and waste nutrient removal using central composite design (CCD). The influences of two key...

Using wastewater to grow algae is probably the most promising route to reduce production costs associated with nutrients and water. In this study, a newly isolated facultative heterotrophic freshwater microalgae strain, Auxenochlorella protothecoides UMN280, was examined for algal growth,...

Promising energy crops such as <i>Jatropha curcas Linnaeus</i> (<i>JCL</i>), which are planted on marginal lands, or microalgae such as <i>Chlorella</i>, which are cultivated in ponds located on mudflats or deserts, have been regarded with high hopes to solve the shortage of food crops and increase the amount of...

Microwave-Assisted Pyrolysis (MAP) is a highly scalable process that has the potential to realize the Distributed Biomass Energy Production System (DBEPS) concept. This study was to illustrate the heating properties of MAP when applied to biomass, and to demonstrate the feasibility of...

The criteria formulated by M. Born for the onset of melting (1939) and lattice stability (1940) are re-examined on the basis of more general considerations of elastic instabilities. With the aid of molecular dynamics simulations, we show that (1) Born's stability criteria are valid only in the...

The objective of this study is to analyze theoretical as well as empirical soundness of the current monetary aggregates (M2) and to propose a broader monetary aggregate (M3), by exploring the functional characteristics and empirical relevance of financial assets. We used annual time series data...

Using a survey of 19,977 children in two provinces, this paper explores the prevalence, correlates and potential consequences of poor vision among children in China's vast but understudied rural areas. We find that 24% of sample students suffer from reduced uncorrected visual acuity in either...

We analyze the policy issue of medical marijuana to illustrate how key virtues of federalism can be used to make a threshold determination as to whether a particular public policy should be subject to federal regulation or reserved for states. When the substantive merits of the policy issue are...

Efficiency wage considerations should be less important for piece-rate pay than for time wages. Therefore, if industry wage differentials reflect efficiency wage factors, then these pay differences should be less sizable and have less explanatory power for piecework than for timework. We test...
