Descriptions of Lower Devonian plants from Yunnan, South China, have revolutionized concepts of diversity and disparity in tracheophytes soon after they became established on land.Sichuan assemblages have received little attention since their discovery almost 25 years ago and require revision.With this objective, fieldwork involving detailed loggin
Brazilian coking coal (Barro Branco seam) were used to produced several binary coal blends with traditional coking coals.The plastic properties of such blends were study by Gieseler plastometry in order to identify possible interactions between coals.The magnitude of the interactions was estimated by the comparison of measured and predicted values
