1. A weak or moderate-intensity tactile stimulus delivered to the siphon skin of Aplysia californica elicits a defensive reflex withdrawal of the gill and siphon into the mantle cavity. The reflex undergoes both short- and long-term habituation and sensitization and has, therefore, been used as a model system to examine various forms of learning. In this paper we describe studies of the response properties of the sensory and motor neurons of the reflex during repeated stimulation at rates that produce habituation. 2. The sensory neurons are slowly adapting mechanoreceptor cells whose frequency of discharge is a monotonic function of controlled-force punctate stimuli delivered to the skin. The majority of the stimulus-response relations could best be described by exponential functions. 3. We examined the stability of the sensory neuron responses in two ways; with punctate stimuli of varying intensity and with water jets of varying intensity. 4. With repeated punctate stimulation at rates which produce habituation in the intact animal the mechanoreceptor discharge showed no decrement. This stability was observed over a 10-fold range of intensities. 5. Weak or moderate intensity water-jet stimuli to the skin also gave stable responses but stronger stimuli caused the mechanoreceptor response to fatigue. 6. We examined the stability of the motor responses by using intracellular depolarizing current pulses to produce repetitive bursts of action potentials in gill motor neurons while monitoring the gill contractions with a strain gauge, photocell, or videotape recorder. The photocell and strain gauge were alternatively used in the same experiment. Gill contractions monitored with the photocell were stable, whereas those monitored by the strain gauge showed decrement. An independent measure of gill contraction, videotape recording, confirmed the results obtained with the photocell and showed that the gill contractions following repeated intracellular depolarization of the motor neurons were stable.

The present paper reports on the failure of a test embankment built on a soft, sensitive, and cemented clay in Saint-Alban, Quebec. The embankment was built as a first stage of a research program aimed at studying the short and long term behavior of embankments on soft clay foundations.A complete description of the embankment, of the instrumentation, and of the failure is given, followed by the analysis of the failure performed on the basis of different assumptions of fill behavior and of vane strength values mobilized in the clay crust. The analyses show that the assumptions of full mobilization of friction in the fill seems to be the most representative of the fill behavior in the present case and that a suitable factor of safety is obtained only when a reduction of vane strength is assumed to act in the crust.A new approach based on the residual undrained strength is suggested and seems to offer some potential as a valuable means of analyzing the stability of embankments on clay foundations.

The aim of our study was to compare the results of the TTE (transthoracic echocardiography) with the results obtained by the ECG-gated 64 slices CT during the followup of patients with bicuspid aortic valve (BAV), after aortic valve replacement; in particular we evaluated the aortic root and the ascending aorta looking for a new algorithm in the followup of these patients. From January 1999 to December 2009 our attention was focused on 67 patients with isolated surgical substitution of aortic valve; after dismissal they were strictly observed. During the period between May and September 2010, these patients underwent their last evaluation, and clinical exams, ECG, TTE, and an ECG-gated-MDCT were performed. At followup TTE results showed an aortic root of 36.7±4 mm and an ascending aorta of 39.6±4.8 mm. ECG- gated CT showed an aortic root of 37.9±5.5 mm and an ascending aorta of 43.1±5.2. The comparison between preoperative and postoperative TTE shows a significant long-term dilatation of the ascending aorta while the aortic root diameter seems to be stable. ECG-gated CT confirms the stability of the aortic root diameter (38.2±5.3 mm versus 37.9±5.5  mm; <0.0001) and the increasing diameter value of the ascending aorta (40.2±3.9 mm versus 43.1±5.2 mm; P=0.0156). Due to the different findings between CT and TTE studies, ECG-gated CT should no longer be considered as a complementary exam in the followup of patients with BAV, but as a fundamental role since it is a real necessity.

The Covid-19 pandemic has precipitated unprecedented health, social and economic crises across the countries of Latin America and the Caribbean. All countries in the region moved quickly to implement rescue policies to safeguard lives and livelihoods. The rescue phase continues along with the challenge of orchestrating the post-COVID-19 economic recovery: designing packages of investments and initiatives to stimulate employment, liquidity, reignite sustainable and inclusive economic growth and transition towards net-zero emission and climate-resilience economies to confront the worsening climate and ecological crisis. These policies must be sustainable in the short and long term and bring institutional, social, economic/financial, and environmental co-benefits. This working paper proposes criteria for evaluating the sustainability of recovery investments and initiatives, to serve as a checklist for stakeholders to use to ensure a recovery that builds an inclusive, sustainable and resilient future for all.

The most crucial part for the economic development of a country is maintaining the stability of inflation to create a positive climate for economic and business activities. A number of efforts can be performed to achieve stable inflation and increase economic growth by designing monetary policy incorporating the variables of Bank Indonesia Sharia Certificate (SBIS), Islamic Interbank Money Market (IIMM), and Financing. Drawing on this issue, the in-hand study aims to examine the effectiveness of Islamic monetary policy transmission, using the instruments of SBIS, IIMM, and Financing, on inflation and economic performance (GDP) from the period of January 2011 to December 2020. Using secondary data, this study employs VAR/VECM approach by the assistance of Eviews program. The results reveal that in the short term period, inflation is significantly influenced by the IIMM, while GDP t is affected by the GDP t-1 and financing activities. In the long term period, both inflation and GDP are determined by SBIS and financing activities. In general, this study results in a conclusion that the variables of IIMM, financing activities, and GDP t-1 influence the economic performance both in short and long term periods. These results contribute as fruitful insights to developing financial strategies and monetary policy to maintain stable inflation and improve economic performance of a country.

The stability of human plasma composition was investigated by NMR, considering different collection tubes, time at room temperature (RT), short- and long-term storage conditions and up to 5 consecutive freeze–thaw cycles.
