Radiation effects in nitride read-only memories

2010

Abstract We report on the influence of different types of radiation on the nitride read-only memories (NROM®). The memory cells were irradiated by light ions (Boron), X-rays and γ-rays. Memory transistor parameters, such as threshold voltage and subthreshold drain leakage were studied as a function of the accumulated radiation dose and compared to the as-programmed (-erased) devices parameters. Their time evolution was registered in the range from few hours up to 5 months after the irradiation. The NROM® cells showed good radiation robustness up to high accumulated doses. Sufficient program margin (difference of threshold voltage in the programmed state and the read-out voltage level) remai…

Since the beginning of the 20th century, electroencephalography (EEG) has been used in a wide variety of applications, both for medical needs and for the study of various cerebral processes. With the rapid development of the technique, more and more precise and advanced tools have emerged for research purposes. However, the main constraints of these devices have often been the high price and, for some devices the low transportability and the long set-up time. Nevertheless, a broad range of wireless EEG devices have emerged on the market without these constraints, but with a lower signal quality. The development of EEG recording on multiple participants simultaneously, and new technological …

The opportunity of using wave energy converters in a Mediterranean hot spot

2022

The opportunity of using wave energy converter arrays in a hot spot area of the Mediterranean sea was investigated. For this purpose, numerical simulations of wave energy converters together with a simple cost-effective analysis were carried out. The selected study area is one of the most energetic inside the Sicilian channel (Italy). The numerical simulations were performed using the SNL-SWAN (“Sandia National Laboratories – Simulating WAves Nearshore”) spectral model with an unstructured mesh. The power absorbed from thirteen Wave Energy Converter (WEC) devices was computed. In particular, Pelamis, Wave Dragon, Oyster 2, Wavestar, B-HBA, B-OF, Bref-HB, Bref-SHB, F–2HB, F–3OF, F-HBA and F-…

Surgical management of acute angle-closure glaucoma after toric implantable contact lens implantation

2006

A case of pupillary block after implantation of an implantable contact lens (ICL) is reported, and surgical management and prevention are discussed. In a myopic patient, the best corrected visual acuity in the right eye was 20/50 with -15.50 -3.00 x 175. After uneventful implantation of an ICL, painful acute glaucoma developed with an intraocular pressure beyond measurable values. Apparent anterior vaulting of the ICL suggested a sizing problem. In a situation of a mid-wide dilated pupil, immediate explantation of the ICL was performed. Then, using a preoperative iris photography as guidance, an anterior chamber iris-claw toric phakic intraocular lens was implanted. On postoperative examina…

The spontaneous use of memory aids at different educational levels

1996

Three groups of students in different educational levels: 8th–9th grade students (average age 15); 10th–11th grade students (average age 16); and college students (average age 21), completed a metamemory questionnaire on the use of external, general, and formal memory aids in everyday life and study situations. Short-term repetition, mental rehearsing, and summary elaboration were the most frequent aids. The least frequently used were those that require a special training to be used effectively (e.g. Digit-letters and method of loci). There were differences in the use of general memory aids due to education level, but not in the case of external and formal memory aids. Results showed also t…

EFFECT OF THE INTRODUCTION OF PAUSES BETWEEN REPETITIONS IN THE CAPACITY TO SUSTAIN MAXIMAL MAGNITUDES OF PEAK VELOCITY DURING BENCH PRESS

2013

Background An important number of sport modalities sustain its performance in the capacity to repeat efficiently a sport movement without fatigue. However, it is a fact that this mechanism will appear and affect the athletes9 velocity magnitudes. The aim of this study was to compare the Peak Velocity (PV) in two protocols: Traditional Training (TT) vs. 20 s inter-repetition rest (IRR) with the Optimal Load (OL) for the maximal Power output (OL: 50.7±8.0% of 1-RM). Methods Fifteen male, physical education students, participated in this study (age: 23.1±1.6 years; height: 177.1±7.7 cm; mass: 76.2±9.2 kg; 1-RM: 93.8±14.3 kg; 1-RM/mass: 1.24±0.21). After the validation of the bench press 1-RM a…

Effect of Material Organization on Memory in an Incidental Learning Task Performed under Repeated Maintenance

2009

The present paper investigates the effect of organizational variables on long term retention of material recycled under maintenance rehearsal. Subjects repeated a series of words as a distracting task, expecting to be tested on the recall of numbers (GLENBERG & ADAMS, 1978). An unexpected test on the recall of words showed the superiority of the recall of organized words, and a significant interaction of organization by time spent in repetition of the distractor material. The present experiment, because of the requirement of written, and not oral, repetition of the distractor material, is a more stringent test of the postulated consequences of type I rehearsal according to leve1 of processi…
