In this article, we studied the types of low-frequency magnetospheric micropulsations Pc5 and Pc6 (1 - 6 mHz), during three magnetic storms, using ground magnetic observations. One of the main motivations of this study was to produce scientific knowledge on the subject in order to fill knowledge gaps in this region, collaborating with existing bibliographies. The data were recorded in a series of six Brazilian stations close to the Dip Equator (dip = 0), with using data from the Ascension Island observatory. Pulse trains were found to occur simultaneously with almost identical waveforms, with significant amplitude increase near magnetic local noon. Amplitude spectra showed a clear similarity in all equatorial seasons. The results obtained were compared with studies performed in regions with similar low latitudes. The possible mechanisms that induced these micropulsations and the peculiarities presented by these data were also discussed in this article.展开更多

Based on this study, we have shown that the human glycemic management system must be seen as coupled and integrated by four subsystems, namely, production system, consumption system, distribution system, control system, and also it should be seen as coupled to external noxious factors/stressors, if not we show that the glycemic homeostasis analysis might be defective and might induce, in many cases, a misdiagnosis of the causes of the persistent hyperglycemia under consideration. Also, in this work, some considerations were presented to show that anomalies in the cerebral glycemic control through the glucose sensor neurons might be a possible cause/origin of some of the glycemic abnormalities and dysfunctions (however, not only the known related hypoglycemia but also hyperglycemia) that occur in childhood. Finally, it is shown that persistent novel external noxious factors of modernity or noxious factors already known, but amplified by modernity, such as persistent stress, media induced fears, and phobias, environmental pollution, and electromagnetic pollution, can and should also be considered as possible precursors for the development of anomalies in the juvenile homeostatic glycemic system that might well be, if intense and persistent, the driver of the worldwide observed T1DM epidemic events.展开更多
