The Way

Recent progress in comparative linguistics, distributional typology, and linguistic geography allows a unified model of Uralic prehistory to take shape. Proto-Uralic first introduced an eastern grammatical profile to central and western Eurasia, where it has remained quite stable. Proto-Indo-European and Proto-Uralic had no connection, either genealogical or areal, until the spreading Indo-Iranian branch of Indo-European came into contact with the already-diverged branches of Uralic about 4,000 years ago. A severe and widespread drought beginning about 4,200 years ago cleared the way for a rapid spread of Uralic-speaking people along the Volga and across southwestern Siberia. It also contributed to the sudden rise of the Seima-Turbino bronze-trading complex, one component of the Uralic spread mechanism. After the initial spread, the Uralic daughter languages retained their Volga homelands remarkably stably while also extending far to the north in a recurrent Eurasian pattern.

High temperature biomass gasification has been performed in a prototype concentrated solar reactor. Gasification of biomass at high temperatures has many advantages compared with historical methods of producing fuels. Enhancements in overall conversion, product composition ratios, and tar reduction are achievable at temperatures greater than 1000°C. Furthermore, the utilization of concentrated solar energy to drive these reactions eliminates the need to consume a portion of the product stream for heating and some of the solar energy is stored as chemical energy in the product stream. Experiments to determine the effects of temperature, gas flow rate, and feed type were conducted at the high flux solar furnace at the National Renewable Energy Laboratory, Golden, CO. These experiments were conducted in a reflective cavity multitube prototype reactor. Biomass type was found to be the only significant factor within a 95% confidence interval. Biomass conversion as high as 68% was achieved on sun. Construction and design considerations of the prototype reactor are discussed as well as initial performance results.

A major problem in the current biomass gasification systems is the formation of tar. The condensed tar at low temperatures may cause blockage and pollution of downstream equipments, as well as environmental pollution. Therefore, the removal and conversion of tar are the key issues for biomass gasification. At present, the common methods of tar removal are mainly mechanism methods, thermal cracking and catalytic cracking. In this paper, the catalytic cracking method and its advantages and disadvantages are discussed.
