1. The blood of Chortophaga viridifasciata was analyzed. The average concentrations of inorganic cations expressed as milligrams per cent are: sodium, 250.66; potassium, 13.52; calcium, 11.40; and magnesium, 51.15. The osmotic pressure of the blood at 0 degrees C. is 10.7 atmospheres. Protein and non-protein nitrogen, expressed as milligrams per cent, are 253.4 and 140.0, respectively. 2. The b...

The performance of (bio-)signal classification strongly depends on the choice of suitable features (also called parameters or biomarkers). In this article we evaluate the discriminative power of ordinal pattern statistics and symbolic dynamics in comparison with established heart rate variability parameters applied to beat-to-beat intervals. As an illustrative example we distinguish patients su...

The ECG (electrocardiogram) signal provides a lot of valuable information about the condition of the heart. Many cardiac problems are visible as distortions in the ECG. The analysis of heart beat cycles in an ECG signal is vital for long-term monitoring of heart patients. However, in long-term monitoring, it is a very tedious and timeconsuming task to analyze the ECG recording beat by beat. Thi...

This paper describes the development of a heart rate monitor system based on a microcontroller. It offers the advantage of portability over tape-based recording systems. The paper explains how a single-chip microcontroller can be used to analyse heart beat rate signals in real-time. In addition, it allows doctors to get the heart beat rate file of the patient by email every twenty four hours. I...

OBJECTIVE To determine the effect of ocular blinkers on driving horses' reactions to visual and audible stimuli. DESIGN Balanced crossover trial with horses randomly assigned to either wear blinkers or not wear blinkers first or second, then subjected to repeated sequences of four distinct stimuli (chain rattle, cap gun, umbrella opening, and shaking of an aluminum can containing coins). Two ...

Based on our numerical heart and chest model with stochastically modifiable action potential duration (APD) parameters, the consequences of diminished subepicardial cell-to-cell coupling were studied on beat-to-beat repolarization heterogeneity. Pathological action potential durations and transmural gradient (TG) mean values (M) were assumed in the apical segment of the five-layer heart model, ...

Increased blood pressure variability (BPV) and decreased inter-beat interval (heart rate, respectively) variability (IBIV, HRV respectively) are associated with cardiovascular disorders. The aim of this study was to evaluate the reproducibility of BPV and IBIV (HRV) in young healthy individuals. Blood pressure and inter-beat intervals (instantaneous values of heart rate, respectively) were reco...

1. The isolated, intact heart of the marine arachnid Limulus polyphemus continues to beat in vitro for many hours. Application of ^aminobutyric acid (GABA) decreased the heart beat frequency with a threshold of 3xlO~ 7 moir 1 and an EC50 of 2.0±0.6xlO"moll" (mean±s.D., N = 8). At lO^mol l" 1 and above the heart beat was completely and reversibly inhibited. 2. The agonist potency profile of the ...

Nowadays, nobody in this world is ready to lookwhat’s happening around them. Even though, if any accident occurs no one cares about it. This is an intention to implement an innovative solution for this problem by developing an Accident detection System using android smart phone from the accident zone.This system has been developed and implemented using the heart beat sensor based mobile technol...
