Biodiesel production from Jatropha curcas: Integrated process optimization por Huerga, Ignacio Roberto, Zanuttini, María Soledad, Gross, Martin Sebastian, Querini, Carlos Alberto

“…Both in large and small scales, there have been numerous developments and research with the aim of generating fuels and energy using different raw materials such as alternative crops, algae and lignocellulosic residues. In this work, Jatropha curcas plantation from the North West of Argentina was studied, with the objective of developing integrated processes for low and medium sizes farms. …”

Telomeric features of Theileria parva mitochondrial DNA derived from cycle sequence data of total genomic DNA por Shukla, G.C., Nene, Vishvanath M.

“…The limited protein coding capacity, rRNA gene fragmentation and TIR sequences of the parasite mtDNA is similar to that described for the 15.8 kbp linear mtDNA of Chlamydomanas reinhardtii, a unicellular green algae (3). In an attempt to complete the sequence analysis of the ends of the parasite mtDNA we have taken advantage of cycle sequencing. …”

Geokemisk undersökning vid Rävlidmyrgruvan, Västerbottens län : provtagning, analys och förslag till åtgärder por Frandsen, Sara

“…Addition of sewage sludge to the pit lake should favour an increased production of algae. Decomposition of the algae may create reducing conditions that should favour the formation of precipitated metal sulphides.…”

Interrill erosion in the sloping lands of northern Laos subjected to shifting cultivation por Chaplot, V., Khampaseuth, X., Valentin, Christian, Le Bissonnais, Y.

“…In addition, water erosion decreased with increasing proportion of structural crusts, probably due to their higher hardness, and when cultivation follows a fallow period rather than after a long period of cultivation due to the greater occurrence of algae on the soil surface, which affords physical protection and greater aggregate stability through binding and gluing. …”

The effect of riparian buffer properties on spider communities and aquatic-terrestrial food-web lingages por Ramberg, Ellinor

“…PUFAs are physiologically essential for animals, and some are exclusively producedby algae in aquatic environments. These aquatic PUFAs can therefore be used as biomarkers to track the uptake of algal-derived aquatic subsidies into terrestrialfood webs. …”
