Systematic Approach to Processing and Analysis Diagnostic Indicators of Electrocardiograms Based on Labview

Introduction. Cardiovascular disease occupies an important place throughout the world, which necessitates the development of more effective modern means of diagnosis and treatment. The primary diagnosis of heart disease is based on analysis and processing of an electrocardiogram (ECG). Despite the fact that there are many methods and algorithms for ECG analysis and processing, one of the urgent problems of cardiology remains to obtain the most complete information about heart electric potential, respectively, the behavior of the waves P, Q, R, S and T.Aim. Development of algorithms and software for processing and analysis of electrocardiograms (ECGs), as well as calculation of heart rate and detection of arrhythmias based on Labview.Materials and methods. The methods for removing noise using the wavelet transform method to eliminate baseline deviation ,to extract ECG signs ,to calculate heart rate and to detect arrhythmias based on Labview have been adopted as a mathematical apparatus for processing and analyzing ECGs.Results. Organizing of the ECG database, developing algorithms for converting the ECG file of the database into a useful format for Labview, processing of the ECG signal with removing noise from the original ECG signal, extracting signs for obtaining ECG diagnostic indicators, calculating heart rate and detecting arrhythmias.Conclusion. An analysis of the results demonstrates that systematic approaches to evaluating ECG signals allow to avoid one-way decisions and to integrate different methods into an integrated system of ideas of the state. The implementation of the proposed algorithms using Labview programming system ensures the removal of noise and artifacts, the extraction of the necessary ECG signs, the calculation of heart contractions and the detection of arrhythmias.Introduction.

Effects of Compost on Mycelia Growth and Fructification, Mineral Elements and Proximate Composition of Pleurotus pulmonarius (Fries)

Studies were conducted on the growth and cultivation of Pleurotus pulmonarius (Fries) singer on lingocellulosic waste. Long composted substrate formulations of sawdust (86%) + rice bran (10%) + cassava peel (4%) supported the longest mycelia growth and density. Long composted also produced larger fruitbodies and significant increase in number of fruitbodies and compost % yield compared with uncomposted substrate having the same formulations. The mineral elements of Mg, Cu, Fe, Mn, Na, K, and P were found to increase from very young to mature fruitbody of both composted and uncomposted substrate with preponderance of potassium. Similar results were obtained for crude protein. However, organic carbon and organic matter tend to decrease from very young to mature fruitbody of composted and uncomposted substrates.Keywords: Composting, Fructification, Mineral Elements Pleurotus pulmonarius, Organic carbon and Organic matter

A new in the world of emerging organization introduced in line with the term information technology and information systems, namely how a well oriented organization and interact using computers, telecommunications applications and suggestions to improve its performance significantly. Thedevelopment of science and technology information has been covering the world community today. As part of the world community, we certainly do not want to miss and information technology is growing. There are many ways that can be taken to determine the technological developments that are happening.One way is to use a computer as a means for processing and information. Similarly, the National Unity Politics and Public Protection Provincial Government of North Sumatera are still many difficulties in employee annual tax data processing to minimize the time and cost of operations. Therefore the authortries to make design knowledge Income Tax Calculation Application of Article 21 In Politics of National Unity and Community Protection Provincial Government of North Sumatera by using Visual Basic 6.0and Ms. Acces, this application can manage the data of tax calculation and overcome existingdifficulties
