13. Rotational Steady Waves in a Low-pressure Region
ABSTRACT Nonlinear steady rotational waves in a low-pressure region are investigated. The problem is formulated in a simplified canonical domain through the use of a conformal mapping, which flattens the free surface. Steady waves are computed numerically using a Newton’s method and classified into three types. Besides, our results indicate that there is a

14. Potential of forage and grain yield of maize genotypes in the Brazilian semiarid region
ABSTRACT Maize is importance in the semiarid region due to its forage potential. However, the large number of hybrids on the market hampers the selection of the hybrid by the producer. Given the above, the objective of this paper is to identify genotypes with productive potential for forage and grain production according to the characteristics of the semiari

17. A note on the Brazilian cross-state debt connectedness
Abstract We address the cross-state indebtedness (DCL/RCL) variation connectedness using 89 bimonthly data from 2006b6 to 2021b4, based on the indices proposed by Diebold and Yilmaz (2009, 2012, 2014). This framework enables us to infer about the direction, and the strength of bilateral spillovers for a large number of simultaneously interacting variables in

20. Assessment of Urban Contamination by Sewage in Sediments from Ipojuca River in Caruaru City, Pernambuco, Brazil
The Ipojuca River is considered the third most polluted river in Brazil due to the intense anthropogenic activities in the surrounding urban areas. The most important effluent is sewage discharge, which is responsible for considerable contamination. Traditional analyses (infrared spectroscopy, organic matter (OM), elemental analysis and granulometry) and adv

24. Non-alpine primary thyroid angiosarcoma
SUMMARY Thyroid angiosarcoma is an extremely rare malignancy, which occurs more frequently in the alpine region, likely associated with iodine deficiency and endemic goiter. This is an aggressive neoplasm that usually harbors a poor prognosis. We report the case of a 49-year-old Portuguese female patient presenting with a large nodule in the anterior neck re
