Environmental and endocrine assessment of sheep welfare in a climate-controlled...
Baptista, F.J.; Marques, R.; Castro, J.A.; Shahidian, S.; Fitas da Cruz, V.; Sales-Baptista, E.The nutritional status of sheep grazing in the Montado ecosystem varies considerably throughout the year, due to variations in the availability and quality of pastures, strongly influenced by the typical climatic conditions of the Mediterranean region: dry summer and autumn with very little rain. These variations lead to severely restricted feeding for approximately half the year, causing under-nutrition, limit...
Impact of marked weight loss induced by bariatric surgery on bone mineral densi...
Pereira,F.A.; Castro,J.A.S. de; Santos,J.E. dos; Foss,M.C.; Paula,F.J.AData about the impact of bariatric surgery (BS) and subsequent weight loss on bone are limited. The objective of the present study was to determine bone mineral density (BMD), bone remodeling metabolites and hormones that influence bone trophism in premenopausal women submitted to BS 9.8 months, on average, before the study (OGg, N = 16). The data were compared to those obtained for women of normal weight (CG, ...
Health in early adulthood: the contribution of the 1978/79 Ribeirão Preto birth...
Barbieri,M.A.; Bettiol,H.; Silva,A.A.M.; Cardoso,V.C.; Simões,V.M.F.; Gutierrez,M.R.P.; Castro,J.A.S.; Vianna,E.S.O.; Foss,M.C.; Dos Santos,J.E.The increase in non-communicable chronic diseases of adults is due to demographic changes and changes in the risk factors related to physical activity, smoking habits and nutrition. We describe the methodology for the evaluation of persons at 23/25 years of age of a cohort of individuals born in Ribeirão Preto in 1978/79. We present their socioeconomic characteristics and the profile of some risk factors for ch...
Hornification—its origin and interpretation in wood pulps
Fernandes Diniz, J. M. B.; Gil, M. H.; Castro, J. A. A. M.Although perfectly diagnosed in terms of the occurrence of physical changes, the hornification phenomenon, in its origin, has frequently been associated with the formation of irreversible or partially reversible hydrogen bonding in wood pulps or paper upon drying or water removal. Its characterisation has therefore been confusing and unsatisfactory. The authors propose that a sufficiently varied source of exper...
Sensor Fault Detection and Identification in a Pilot Plant Under Process Control
Afonso, P. A. F. N. A.; Ferreira, J. M. L.; Castro, J. A. A. M.The experimental evaluation of an automatic procedure for sensor fault detection and identification in a real process under closed-loop control is the objective of the present research. The scheme proposed here is very robust to faults in the main sensors of a multiloop control system, thus improving safety and reliability of plant operations. A state variable transformation is carried out in order to derive a ...
Visceral leishmaniasis in Teresina, state of Piauí, Brazil: preliminary observa...
Vexenat,J. A.; Castro,J. A. Fonseca de; Cavalcante,R.; Tavares,J. P.; Silva,M. R. B. da; Batista,W. H.; Campos,J. H. Furtado; Howard,M. K.; Frame,I.A Leishmania donovani-complex specific DNA probe was usedto confirm the widespread dissemination of amastigotes in apparently normal skinof dogs with canine visceral leishmaniasis. When Lutzomyia longipalpis were fed on abnormal skin of five naturally infected dogs 57 of 163 (35 per cent) fliesbecame infected: four of 65 flies (6 per cent) became infected when fed on apparently normal skin. The bite of a single...
