The Use of Rate of Increase of Intraventricular Pressure During Isovolumetric Contraction (dP/dt) in Assessment of Left Ventricular Function in Acute Coronary Syndrome
...Show More Authors

BACKGROUND: Acute coronary syndrome (ACS) is the clinical manifestation of acutely diminished coronary arterial blood supply. The rate of increase of intraventricular pressure during isovolumetric contraction (left ventricular dP/dt) represents the rate of change of pressure during ejection. OBJECTIVE: The aim of this study is to evaluate the usefulness of the rate of increase of intraventricular pressure during isovolumetric contraction (dP/dt) in assessment of left ventricular function in patients with acute coronary syndrome and its relation to certain clinical and echocardiographic features. PATIENTS AND METHODS: The study is a cross sectional study including 50 patients with an established diagnosis of acute coronary syndrome. The study was performed in Baghdad Teaching Hospital during the period between 2/2/2013 and 5/3/2014. History was taken from all patients and recoded using a specially prepared questionnaire paper. Left ventricular internal dimensions at end diastole (LVIDd) and end systole (LVIDs) were measured using M-mode echocardiography to asses left ventricular systolic function (ejection fraction). Pulse Doppler tracing of the transmitral flow velocities and tissue Doppler image (TDI) mitral annular velocities were obtained from the apical four-chamber view to assess left ventricular diastolic function. Doppler-derived dP/dt was determined from mitral regurgitation (MR) spectral flow RESULTS: The study included 50 patients (31 males and 19 females, mean age of 65.26 ± 5 years). Low dP/dt values were found in 42 patients (84%). Low dP/dt values were found more in the age group (51-60 yrs) (p value < 0.05). The mean age of patients with low dP/dt (<1000) was (65.62 ± 5yrs) and that of patients with normal dP/dt (≥ 1000) was (63.38 ± 5 yrs) with no significant difference (p value > 0.05). Low dP/dt value was significantly associated with smoking and positive family history and not significantly associated with male sex, hypertension, and diabetes mellitus. No significant association was found between low dP/dt value and type of presentation of acute coronary syndrome (p value > 0.05) or ejection fraction (p value > 0.05). It was significantly associated with LV diastolic dysfunction, left atrial size, left atrial pressure, and left ventricular size (p value < 0.05). CONCLUSION: The use of dP/dt is useful for evaluating left ventricular function in patients with acute coronary syndrome.

Cognitive Beliefs and Their Relationship to Self-Organized Learning Strategies at the Preparatory Stage
...Show More Authors

The study aims to identify the level of cognitive beliefs, as well as to identify the level of self-organized learning strategies among intermediate school students. The study also aims to identify the differences in the level of self-organized learning strategies among intermediate school students in term of gender, branch (scientific, literary). In order to achieve the research objectives, the researcher designed a scale to measure the cognitive beliefs. As for the scale of self-organized learning strategies, the researcher adopted a scale of (Pintrich et al. 1991), which was translated by (Izzat Abdelhamid, 1999) , For self-organized learning strategies, the sample consisted of (400) students from the research population, whic

Analysis the economic and financial phenomena and other requires to build the appropriate model, which represents the causal relations between factors. The operation building of the model depends on Imaging conditions and factors surrounding an in mathematical formula and the Researchers target to build that formula appropriately. Classical linear regression models are an important statistical tool, but used in a limited way, where is assumed that the relationship between the variables illustrations and response variables identifiable. To expand the representation of relationships between variables that represent the phenomenon under discussion we used Varying Coefficient Models

Enhancing the Delta Training Rule for a Single Layer Feedforward Heteroassociative Memory Neural Network
...Show More Authors

In this paper, an algorithm is suggested to train a single layer feedforward neural network to function as a heteroassociative memory. This algorithm enhances the ability of the memory to recall the stored patterns when partially described noisy inputs patterns are presented. The algorithm relies on adapting the standard delta rule by introducing new terms, first order term and second order term to it. Results show that the heteroassociative neural network trained with this algorithm perfectly recalls the desired stored pattern when 1.6% and 3.2% special partially described noisy inputs patterns are presented.

The first problem, minimizing the multi-criteria, which include Total Completion Time, Total Late Work, and Maximum Earliness Time (∑𝐶𝑗, ∑𝑉𝑗, 𝐸𝑚𝑎𝑥), and the second problem, minimizing the multi-objective functions ∑𝐶𝑗 + ∑𝑉𝑗 +𝐸𝑚𝑎𝑥 are the problems at hand in this paper. In this study, a mathematical model is created to address the research problems, and some rules provide efficient (optimal) solutions to these problems. It has also been proven that each optimal solution for ∑𝐶𝑗 + ∑𝑉𝑗 + 𝐸𝑚𝑎𝑥 is an effic

Some of the issues that have become common in our society recently after the Americans entered our country and were rubbed by some security agencies: obtaining some information from children, and the serious consequences that may lead to the lives of innocent people, became common interrogation of some security agencies and rely on their words.
There are significant cases where their testimony needs to be heard, such as their presence in some places where incidents are not witnessed by others, such as schools or being witnesses to certain crimes.
I saw the study of this case in the light of Sharia and law
