In the last week of November 2012, we announced that a strong electrotelluric disturbance, which we judged to be a Seismic Electric Signal (SES) activity, was recorded at station Assiros located in Northern Greece. This disturbance was actually followed by an Mw5.8 earthquake on 8 January 2013 in North-Eastern Aegean Sea. Here we show that, by analyzing this SES activity and employing the natur...

This paper presents an oscillometric blood pressure (BP) measurement approach based on the active control schemes of cuff pressure. Compared with conventional electronic BP instruments, the novelty of the proposed BP measurement approach is to utilize a variable volume chamber which actively and stably alters the cuff pressure during inflating or deflating cycles. The variable volume chamber is...

Fluid therapy is important for many medical conditions in veterinary patients. The assessment of patient history, chief complaint, physical exam findings, and indicated additional testing will determine the need for fluid therapy. Fluid selection is dictated by the patient's needs, including volume, rate, fluid composition required, and location the fluid is needed (e.g., interstitial versus in...

Several methods to experimentally induce panic cause profound acid-base disturbances. Evidence suggests that CO(2) inhalations, lactate infusions and, to a certain extent, voluntary hyperventilation can conceivably lead to a common scenario of brain acidosis in the face of disparate intravascular pH alterations. The importance of this event is reflected in data that support a model in which exp...

A historical review of calculation abilities is presented. Counting, starting with finger sequencing, has been observed in different ancient and contemporary cultures, whereas number representation and arithmetic abilities are found only during the last 5000-6000 years. The rationale for selecting a base of ten in most numerical systems and the clinical association between acalculia and finger ...

This paper presents a number of responses to Gordon de Brouwer’s criticisms of my paper on monetary policy in Indonesia. Among other things, it argues that de Brouwer has failed to disentangle the impact of two exogenous disturbances on prices—and relative prices—during the crisis and post-crisis period. These disturbances were capital flight, which resulted in real depreciation of the rupiah, ...

This paper presents an experimental study on the dynamics of a ducted, conical, laminar premixed flame subjected to low amplitude acoustic excitation from upstream. The heat release response of the flame to velocity disturbances is investigated through measurement of the so called ‘flame transfer function’ for a wide range of forcing frequencies. The results are compared with those predicted by...

Thle management of gastro-enteritis with dehydration and electrolyte and acid-base disturbances presents one of the commonest clinical problems in hospital paediatric practice in Capetown. A large proportion of the 150,000 attendances at the outpatient department of the Red Cross War Memorial Children's Hospital are concerned with gastro-enteritis. During the summer months up to 90 or more dehy...

The renal proximal tubule (PT) plays a major role in whole-body pH homeostasis by secreting H into the tubule lumen. Previous work demonstrated that PTs respond to basolateral changes in [CO2] and [HCO 3 ] by appropriately altering H secretion—responses blocked by the ErbB inhibitor PD168393, or by eliminating signaling through AT1 angiotensin receptors. In the present study, we analyze phospho...
