Sugarcane bacilliforin virus (SCBV) was detected in the world collection of sugarcane gerinplasm at Cannanore in recent years. The characteristic foliar syinptolns were freckles, chlorotic stripes of vaiying length, narrowing of leaves, stunted growth, presence of internodal cracks and a "buizclzy top" appearance. Among the different genotypes, those of Sacckarum oflcinaruin appear most prone t...

This paper provides simple, transparent intuition for the perhaps surprising and certainly widely debated empirical findings of ”environmental Kuznets curves”, i.e. U-shaped relationships between per-capita income and indicators of environmental quality. We consider one possible component of such relationships: the linkage between income and household choices that impact upon the environment. O...

Methanogenic communities that degrade alkanes have been reported. However, little is known about the key players involved in the process. Methanogenic hexadecane-degrading consortia were enriched from an oilfield (Shengli, China). The microbial dynamics during the transfer incubations were monitored using terminal restriction fragment length polymorphism (T-RFLP) fingerprinting of 16S rRNA gene...

While much has recently been written about the overall effectiveness of economic education in the U.S. (see Becker, 1997, e.g.), very little systematic research has been done on the economic education of African Americans at Historically Black Colleges and Universities (HBCUs). This paper takes a step toward improving the understanding of economic education at HBCUs by examining the learning ou...

Vernonia polyanthes Less. (Asteraceae), popularly known as "assa-peixe", is a plant species used in Brazilian traditional medicine for the treatment of cutaneous damage, cicatrization, inflammation, and rheumatism. Based on these ethnopharmacological findings, the current study evaluated the topical anti-inflammatory effects of the hexane (HEVP) and ethyl acetate (EAEVP) extracts from V. polyan...

We model greenhouse gas (GHG) emissions by countries as a dynamic game in which the emissions increase atmospheric concentrations of GHG that negatively affect all countries’ welfare. Each country in each time period chooses a level of emissions, understanding that the combination of all countries’ emissions influences the evolution of the GHG stock. We allow for heterogeneities in countries’ p...

I provide a novel dynamic model with private provision of public bads and investments in technologies. The analysis is tractable and the MPE unique. By adding incomplete contracts, I derive implications of and for international climate treaties. While the non-cooperative equilibrium is bad, short-term agreements are worse due to hold-up problems. A long-term agreement should be more ambitious i...

Objective: Asafoetida (Ferula assa-foetida) is known as a valuable remedy for whooping cough, pneumonia, bronchitis in children and asthma treatment in folk medicine. In the present study the relaxant effects of the asafoetida on tracheal smooth muscle of guinea pigs and its probable mechanism(s) were examined. Materials and Methods: The relaxant effects of three cumulative concentrations of t...
