OBJECTIVE To evaluate suicide seasonality in the city of São Paulo within an urban area and tropical zone. METHOD Suicides were evaluated using the chi-square test and analysis of variance (ANOVA) by comparing monthly, quarterly and half-yearly variations, differentiating by gender. Analyses of time series were carried out using the autocorrelation function and periodogram, while the signific...
We propose a method to infer the coupling structure in networks of nonlinear oscillatory systems with multiple time scales. The method of partial phase synchronization allows us to infer the coupling structure for coupled nonlinear oscillators with one well-defined time scale. The case of oscillators with multiple time scales has remained a challenge until now. Here, we introduce partial recurr...
در این تحقیق گیاه lycium shawii که یکی از گیاهان متعلق به تیره solanaceae می باشد و پراکندگی محدودی در جنوب ایران خصوصا استان هرمزگان دارد.با توجه به مشاهده اثر آنتی باکتریال بسیار قابل توجه از دیگر گونه های جنس lycium بر آن شدیم تا برای اولین بار اثر ضد میکروب l.shawii را علیه 4 سوش باکتریایی شامل:استافیلوکوکوس اورئوس , استافیلوکوکوس اپیدرمیدیس , سودوموناس آئروژینوزا, اشرشیاکلی با روش mic بر...
Statistical analysis is, in fact, an error analysis. A statistical test does not guarantee reliable results, it only quantifies the probability of error of a given conclusion.1 While reading the articles of this journal, you will find a p-value. For instance, the article by Garib et al2 describes the p-values for a given variable at two different moments: this p-value, also known as false-posit...
1) Be able to perform the key steps to hypothesis testing 2) Understand the concept and use of the alpha value 3) Understand in general terms how the p value is derived 4) Correctly interpret the p value 5) Distinguish between type I and type II error 6) Understand the relationships among sample size, power, type I and type II error 7) Have a general notion of the concept of power as it relates...
abstract objectives gradual increase length and complexity of utterance (gilcu) therapy method is a form of operant conditioning. this type of treatment is very precise and controlled that is done in 54 steps in 3 speech situations consisted of monologue, reading and conversation. this study aimed to examine the effects of gilcu treatment method on reduction of speech dysfluency of school-age...
