Fabrication and characterization of micrometer-scale ZnO memristors

2015

Memristors are an interesting class of resistive random access memory (RRAM) based on the electrical switching of metal oxide film resistivity . They are characterized for exhibiting resistive switching between a high-resistance state (HRS) and a low-resistance state (LRS) and have been recently considered as one of the most promising candidates for next-generation nonvolatile memory devices because of their low power consumption, fast switching operation, nondestructive readout, and remarkable scalability. The device structure is simply an oxide layer sandwiched between two metal electrodes. The switching behaviour is dependent both on the oxide material and the choice of metal electrodes.…

[Validity of the use of penbutolol in essential arterial hypertension].

1990

Thirty patients suffering from WHO I-II class slight-moderate essential arterial hypertension were treated with a beta-blocker (Penbutolol) alone and once a day to assess its antihypertensive effectiveness and its affect on heart frequency, lipid metabolism and kidney function. The drug proved highly effective in reducing P.A.S. and P.A.D. values and no negative influence was documented on lipid metabolism, kidney function or heart frequency.

[Cardiovascular response to sympathetic stimulation in normal subjects with or without familial hypertension].

1990

The aim of our study was to seek out a possible different reactiveness to cardiovascular stimulation tests among normotensives with and without positive family history of essential hypertension. We have studied about 200 inhabitants of Ustica and 49 medicine students, all normotensives according to the World Health Organization and the Joint National Committee criteria. In an isolated room and in a supine position, blood pressure (BP) and heart rate were measured every 30 s for 15 min with an automatic sphygmomanometer. Averages of last 4 measurements were considered baseline values. Then we have carried out mental stress (MS), handgrip and active orthostatism test (AO) in the inhabitants o…
