چکیده: 

The analysis of EEG signals plays an important role in a wide range of applications, such as psychotropic drug research, sleep studies, seizure detection and hypnosis PROCESSING. From years ago hypnosis was known as a method to help the patients in different fields such as reduction of stress, leaving bad habits, pain control and etc. EEG signals during pure hypnosis would differ from those recorded in the normal no hypnotic conditions. There are several methods for analyzing the EEG signal and similarity index method is one of the famous methods in this branch. In this paper the features of EEG signal of three groups of people with different hypnotizability during hypnosis (Fractal, Wavelet Entropy, Frequency Bands) from left-right and frontal-back lobes were extracted and analyzed using Fuzzy Similarity Index Method to find whether there are any significant relations between the function of these HEMISPHERES and hypnotizability degree. Finally after detecting the significancy, we used the selected features were used to classify the subjects into three groups of hypnotizability. The best classification accuracy was obtained 94% (for two classes of features 1. entropy, Higuchi, high frequency, 2. energy and entropy) and the lowest was 87.5% (for entropy, Higuchi and low frequency features).

چکیده: 

Background: Muscle fatigue has been known to influence brain activity, but very little is known about how cortical centers respond to muscle fatigue. Objective: This study was conducted to investigate the effects of muscle contraction and fatigue induced by two different percents of maximal voluntary contraction (MVC) on Electroencephalography (EEG) signals. Material and Methods: In this quasi-experimental study, EEG signals were recorded from twenty-one healthy human subjects during three phases (rest, pre fatigue and post fatigue) contraction of Adductor pollicis muscle (APM) at 30% and 70% MVC. The mean powers of EEG bands (alpha, beta and gamma) were computed offline in the frequency domain. Results: None of the three phases with each percent of MVC revealed significant differences for all bands (p>0. 05). Comparison of two HEMISPHERES showed that right hemisphere gamma band activity was enhanced during pre-fatigue state at 30% MVC (p= 0. 042) and post-fatigue state at 70% MVC (p= 0. 028). Right hemisphere beta band activity also increased prominently at 70% MVC in post-fatigue condition (p = 0. 030). Conclusion: These results suggest muscle contraction and fatigue at 30% and 70% MVC have no significant effect on EEG activity, but the trends of beta and gamma band activities are almost similar in each percent of 30% and 70% MVC. Right brain hemisphere shows more activity than left hemisphere in beta and gamma rhythm after fatigue state at 70% MVC.

چکیده: 

سابقه و هدف: واریکوسل از جمله عوامل ناباروری در مردان است. این بیماری، با تغییر در دما و درناژ وریدهای بیضوی موجب اختلال در اسپرماتوژنز و کاهش باروری می گردد. هر چند واریکوسلکتومی، درمان اینگونه بیماران می باشد اما امروزه روشهای کمک باروری و آماده کردن به روشهای مختلف از جمله Sperm PROCESSING و انجام swin up کمک قابل توجهی به این بیماران جهت بارور شدن می نماید.مواد و روشها: این مطالعه به روش مداخله ای در 155 نفر در سال 83 در مرکز ناباروری دانشگاه علوم پزشکی بابل انجام شد. پارامترهای اسپرم افراد واریکوسل قبل و بعد از PROCESSING مورد بررسی قرار گرفت.یافته ها: میانگین سن بیماران 31.8 سال بود. حرکت اسپرم در Grade III و Grade IV قبل از Sperm PROCESSING بترتیب 53.9% و 12.9% بود که بعد از آماده سازی، بترتیب به 78.8% و 56.8% افزایش یافت. Total motility در گروه کمتر از 40 درصد حرکت اسپرم، از 19 نفر به 87 نفر یعنی بیش از 80 درصد افزایش یافت.نتیجه گیری: نتایج این مطالعه نشان داد که در این نوع بیماران می توان به آماده سازی و جمع آوری اسپرمهای مناسب، شانس باروری را افزایش داد.

چکیده: 

Evaluating the cutting rate (CR) of stones is important in the cost estimation and the planning of the stone PROCESSING plants. This research used regression models to estimate the stones’ CR based on their physico-mechanical characteristics. Stone PROCESSING factories in Mahallat City (Markazi province, Iran) were visited, and the CR of diamond circular saws was recorded on six different travertine stones. Next, the stone block samples were collected from the quarries for laboratory tests. Stones’ porosity (n), uniaxial compressive strength (UCS), and Schmidt hammer hardness (SH) were determined in the laboratory as their physico-mechanical characteristics. Correlation relationships of CR with physico-mechanical characteristics were evaluated using simple and multiple regression analyses, and estimator models were developed. Results showed that multiple regression models are more reliable than simple regression for estimating the stones’ CR. The validity of the developed multiple regression models was verified with the published data of one researcher. The findings indicated that these models are accurate enough for estimating the CR of stones. Consequently, the multiple regression models provide practical advantages for estimating the CR and save time and cost during the planning and design of the stone PROCESSING factories.

چکیده: 

In some point of view, neither Michel Foucault nor Ibn Khaldun are considered philosophers in the conventional classifications, but both are very  important in intellectual and, of course, in philosophical contexts, especially for those who are interested in the deep study of human life from the perspective of political thought.The main concern of two thinkers, one in the 14th century, the other in the 20th century, is the issue  of power, although neither of them provided a precise definition of it. In this article, an attempt has been made to show the place of power and domination in the political thought of both thinkers by examining the thoughts of two thinkers. And in search of an answer to this question, how did Asabiyyah and industry of religion in Ibn Khaldun's thought and social control through self-technology and discipline in Foucault's thought lead to the expansion of the domination of power? This article is written by analytically comparing the opinions of two thinkers based on Ibn Khaldun's most important book called Muqaddimah and Foucault's late works

چکیده: 

One of the most frequent rules in various areas of demonstrative jurisprudence of Two Major Sects of Islam religion is a rule that is known among Shīʿa as “tolerance in the evidence of traditions” (Arabic: التسامح فی أدلّة السنن) and in Sunnī as “latitudinarianism in documents” (Arabic: التساهل فی أسانید). Believers in the general application of this rule have based it for reasons such as consensus (Arabic: إجماع), tradition famous through practice (Arabic: الشهرة العملیّة), and rational judgement (intellectual judgement) and a group of aḥādīth (Arabic: أحادیث, plural form for ḥadīth, literally “talk” or “discourse”) called “Akhbar-e- Man Balagh” (Arabic: أخبار من بلغ). The understanding of the aforementioned narrations and the extent of application of this rule has caused a conflict of opinions among scholars. The narrations containing the excellences of suras of the Holy Book of Quran is one of the fields of application of the rule of tolerance. The present research has explained the types of exposure to this group of narrations based on the rule of tolerance by using descriptive-exploratory method and using library sources and seeks to find a suitable approach about narrations of the excellences of suras (chapters) of the Holy Book of Quran. The interaction with these narrations is organized based on a special reading of the rule of tolerance in the selected approach, which is based on a rational interpretation of the contents of Man-Balagh (Arabic: من بلغ)’s narrations and is compatible with the indications of some verses and traditions. The use of weak narrations containing the excellences of suras (chapters) will be permissible based on this approach considering three conditions and without any certainty of attributing these narrations to Sharʿ (Islamic rules).

چکیده: 

How to profoundly change the beliefs of the polytheists during the age of revelation from the denial of the Prophet (pbuh) to the certainty of his Message and the acceptance of his full guardianship is a question worthy of attention. The order of verses about prophecy based on the order of revelation is the reason to lead a transformative process and a special Quranic method in institutionalizing the belief of prophecy in the lives of Arabs. In the first stage, the Holy Quran in the first Makkī (Arabic: المکّیّ, suras revealed in Mecca) chapters has prepared the community from the motivational side to accept the truth of the Prophet’s (pbuh) prophecy and briefly stating the key issues surrounding it. The Holy Book of Quran at the time of the emergence of oppositions and doubts (the second stage) destroyed the arguments of the polytheists and explained the prophecy and proved its authenticity from a cognitive perspective in the second stage by presenting clear arguments. and the Holy Book of Quran in the third stage after Madanī (Arabic: المدنیّ, suras revealed in Medina) period has undertaken measures in order to fulfill the goals of the Massage by explaining the true position of the Prophet (pbuh) to deepen and operationalize the Prophetic belief through explaining practical duties for the Prophet (pbuh) and behavior based on the acceptance of Walaya (Arabic: ولایة, meaning “guardianship” or “governance”).

چکیده: 

Considering the fact that the words in the intra-religious attitude are considered in two ways, the first is towards jurisprudential words and the second is a rational and conceptual view focusing on their meanings. we have tried to deal with one of the most important issues of intra-religious attitude with a rational approach by descriptive and analytical method, which is the category of "hermeneutic interpretation" of words, especially the most influential idea of interpretation & that is the view of the "spirit of meaning" of Ghazali. After Ghazali, Ibn Arabi used this theory of Ghazali regarding the development of meaning in creating his new idea, and by re-reading Ghazali's idea with a mystical approach, he presented his own theory regarding the expansion of meaning. While accepting the argument of the focal point of the theory of the spirit of meaning, he removes it from the exclusivity to the "linear", and for this purpose, he brought up arguments as well as the Conditions of Hermeneutic Interpretation in this regard. Ibn Arabi's arguments on transversal interpretation include new formulations in the argument, which after him, this theory was favored and accepted by Mulla Sadra, and then it was accepted by his students.
