Induction of a recall deficit by rapid-rate transcranial magnetic stimulation
1994
We used rapid-rate, repetitive transcranial magnetic stimulation (rTMS) for the noninvasive study of verbal recall. Five right-handed normal subjects were studied. Recall followed immediately after presentation of a 12-word list. Focal rTMS was applied with a figure eight coil in trains of 500 ms duration to F7, F8, T5, T6, P3, P4, or O1, O2 at latencies of 0, 250, 500, or 1000 ms during word list presentation. Recall was consistently significantly diminished only after left mid-temporal and bilateral dorsofrontal rTMS at both 0 and 250 ms latencies. We conclude that rTMS may be useful as a non-invasive tool for the study of verbal memory processes.
Progressive versus rapid rate of contraction during 7 wk of isometric resistance training.
2001
The aim of this study was to compare the effects of isometric training performed with progressive versus rapid rate of contraction on the knee extensor neuromuscular properties over a 7-wk period.Sixteen healthy male subjects trained quadriceps femoris muscle in a leg extension machine three times a week during 7 wk. The training sessions consisted of six sets of six maximal isometric contractions. A first group trained by performing progressive contractions lasting 4 s, whereas a second group performed contractions with a rapid rate of contraction (i.e., ballistic contractions) lasting about 1 s.Both groups significantly increased the isometric and isokinetic voluntary torque, and the resp…
Differential Effect on the Determinants of the Late Payments According to the Economic Cycle
2018
From 2004 to 2007, the Spanish financial system grew at a very rapid rate. However, from 2008 to 2012 impairment losses amounted equivalent to 25% of Spanish GDP.The objective of this paper is investigate how have affected the main problems that have suffered the Spanish economy on the late payments on Spanish credit institutions. And to check whether the effect of these problems is different on stages of growth with respect to the stages of crisis.The main results, according the test Chow, confirmed that there is a structural break in the model in 2007. Also the increase in unemployment increases the late payments and this increase is greater in the stages of growth compared to the stage…
The impact of Pleurotus ostreatus on organic matter transformation processes.
2012
This study showed the effect of Pleurotus ostreatus on the external organic matter (OM) transformation processes. The kinetics of these changes were determined. The experiment was conducted as 42-day pot experiment done in four combinations (with four replications). The four combinations of different substrates were: (1) organic, (2) composted hay, (3) organic soil + composted hay, (4) organic soil + composted hay + lead. The study results showed that P. ostreatus had the ability to transform external OM as well as metal–organic complexes. These transformations were reflected in the constant rate of characterized changes and correlation coefficients. The study also indicated the direction o…
