While sports are often viewed from a health perspective or with an emphasis on economic aspects, in this article, the author tries to examine the ethical function of sports and show its dimensions. The existence of some common patterns and attitudes towards sports and the dominance of medical or commercial attitudes towards them has prevented attention to the fundamental ethical aspects of sports. While sports, especially aerobic and non-competitive, are tied to moral virtues. With this in mind, the author suggests that non-competitive endurance sports have three moral functions in the long run. First, it leads to self-understanding, self-awareness and self-knowledge, second, it leads to domination of the body, emotions and feelings, and third, it cultivates many moral virtues, including courage, order, tolerance of pain and wisdom.

The effect of Artemia urmiana nauplii enriched with flaxseed oil on growth performance, survival and fatty acid composition of severum, Cichlasoma severum, larvae (0.3 mg initial weight) was investigated through a completely randomized block design with two treatments, viz., (1) larvae fed with plain nauplii, (2) larvae fed with nauplii enriched with flaxseed oil, in three replications. Results of the first biometry (day18^th), showed a significantly higher survival rate in treatment 1 (81.87±0.29%) than treatment 2 (68.83±1.62%) (P<0.05), but there were no significant differences in the specific growth rates, the average weight and length gains between treatments (P>0.05). At the end of the second period of the experiment (day36_th), significant differences in growth performance and survival rate was recorded between treatment 1 (97.82 ± 1.09%) and treatment 2 (91.16± 1.34%) (P>0.05).  The larvae was also found to convert n-3fatty acids to EPA and DHA.

Problem statement: Today, the issue of thermal comfort has been raised as one of the important factors in the quality of urban open spaces along with physical factors. Basically, citizens tend to be in spaces where they feel thermally comfortable. Due to the effect of various parameters in urban open spaces that affect the thermal comfort of users and the lack of codified principles in this regard, the creation of such a space in an urban area has become difficult to identify and meet the thermal needs of city designers.
Results: Studies showed that in the open spaces of the urban environment, due to the influence of various factors, absolute thermal comfort conditions can not be achieved throughout the day; Rather, thermal comfort conditions are expected to be provided for certain hours. To improve thermal comfort in urban open spaces, elements such as vegetation, water, proper orientation, type of materials, color, activity rate and coverage rate are important. It is obvious that by using these factors and observing the time of presence in the open space of Rudkenar sidewalk, thermal comfort will be provided in it.
Method: The research is applied-developmental in terms of purpose; And is based on analytical method. In this method, in order to study the microclimate, the software simulation technique (Envi met) has been used as one of the most complete simulation software in the field of urban microclimate, and the values ​​of PMV thermal comfort index (average vote prediction) using simulation in different parts of the route The designed sidewalk that has different conditions and situations has been calculated and the changes of two factors of temperature and radiation and its effect on the thermal comfort of Khorramabad river in Lorestan in summer have been studied.
Conclusion: Finally, it was found that factors such as choice of direction, walking time, sidewalk width, the presence of trees and vegetation, shade and water, as well as some user characteristics such as metabolic rate and activity, coverage rate in terms of thermal comfort in this season of the year Has been impressive.

It seems natural to think that Dehqan-e Fadakar did something beyond his duty. But this judgment requires explanation. How come there are most reasons for an action and thus it is praiseworthy, but it is not obligatory? Discussions about supererogation start with this question but go further beyond that. In this short note for Farsi readers, I mention some aspects of the problem of supererogation. Furthermore, I also mention “The Cautionary Account of Supererogation” recently proposed based on the ethical work of Miskawayh (d. 1030). So, I discuss the importance of the problem and mention some neglected resources for further explanation.

In this research, the possibility of asphaltene separation from the vacuum tower residue using the low cost industrial solvents such as 402, 404, 406, and 410 was investigated. In order to separate asphaltene the IP143/01 and ASTM D 3279-07 separation methods were utilized. In order to find the optimal state of asphaltene precipitation, Design of experiments software with three factors of residence time, the solvent-to-feed ratio and the volume percent of 406 solvent to the total solvent of 406 and 410 were used. The results showed that the effectiveness of each parameter in precipitating the asphaltene attributed to the ratio of solvent to feed, the ratio of solvent 406 to total solvent, and the residence time, respectively and there was a significant interaction between the basic parameters. The best asphaltene precipitation of 5.06% of 7.5% happens at the residence time of 36.97 hours, the ratio of solvent to feed of 35.95 ml/gr and the volume percent of 406 solvent to the total solvent of 27.20%. Asphaltene precipitation percentage for the optimal mixture of industrial solvents was 22.5% lower than the precipitated asphaltene from normal heptane solvent. However, according to the solvents price, industrial solvents (410 and 406) were approximately 50% cheaper than normal heptane, and hence on overall, there was a cost savings of more than 20%

In a voice conversion system speech signal of A speaker (i.e. source speaker) is modified so that it sounds as if it had been pronounced by B speaker (i.e. target speaker). This process, sometimes, is called speaker conversion (changing speaker identity). Achieved signal from speaker conversion system is desired to have high quality and very natural. To satisfy this, three major methods are proposed as follows: VQ_based, LMR_based and GMM_based voice conversion methods. DTW is the most popular way to warp corresponded words in two sentences. In this paper, DTW is used to design corresponding transfer function. To decrease the distance between two speakers, DTW warps the couple phonemes of two speakers, instead of two words or couple sentences while a linear temporal transform which depends on phonemes is used for error decreasing. By using other appropriate corrections that are used in learning and designing of the linear transforms, a high quality voice conversion system is achieved.

Proof paradoxes refer to situations in which statistical evidence indicates that a suspect is the perpetrator, yet a conviction based solely on this evidence appears counterintuitive. The prevailing approach to addressing proof paradoxes involves establishing a criterion for distinguishing naked statistical evidence from other type of evidence. Smith introduces normic support as a criterion for the aforementioned distinction. Conversely, Di Bello proposes a modified version of normic support, arguing that the absence of access to undercutting defeaters in naked statistical evidence distinguishes it from other forms of evidence. In this research, we argue, in line with Pollock's perspective, that undercutting defeaters can still be accessed in the context of naked statistical evidence. Furthermore, by focusing on an example of proof paradoxes and drawing on Pollock's arguments-illustrated quantitatively by the base rate fallacy-we demonstrate the effectiveness of undercutting defeaters. Consequently, Di Bello's argument appears to be questionable.

Aim: Oral hygiene must start at a young age. Childhood is the perfect time to start the conversion of knowledge into creative thinking and subsequent health care activity. This study aimed to measure the constructs of the Health Belief Model (HBM) in relation to the oral health practice of female students in Tehran.
Methods: A cross-sectional descriptive study was conducted on 416 grade five female students of elementary schools in the school year of 2016-2017 in Tehran, Iran. Data were collected using an author-designed questionnaire based on the constructs of the HBM. The validity of the questionnaire was confirmed using face validity while its reliability was approved using Cronbach’s alpha statistics. Data were analyzed using Pearson's correlation and regression analysis at 0.05 level of significance.
Findings: According to the findings, the mean age of the participants was 10.88±0.628 years. Pearson's correlation showed that four the HBM constructs of Self-efficacy, Cues to action, Perceived benefits, Perceived barriers were significant predictors for oral health practices (P < 0.05). In addition, the variables of knowledge and socio– economic conditions (mother's educational level, father's educational level, mother's job, father's job and family income) had significant relationship with performance (P < 0.05).
Conclusion: Our study shows that for improving the beliefs related with oral health behaviors, designing educational programs with emphasis on increasing self-efficacy and perceived benefits, and overcoming the barriers to promote oral health behaviors is essential.

Arbitrage is a known economic term, implying simultaneous transaction on commodities. For instance, a Generation Company (GenCo) may involve itself in selling fuel, emission allowance and etc., instead of generating either active or reactive power. Moreover, arbitrage between active and reactive powers can, in turn, be considered. In this paper, arbitrage between active and reactive power is considered from Independent System Operator (ISO) viewpoint. A pool model is employed. ISO runs an optimization problem, by which, it could determine and predict GenCos behaviours; in terms of participating in active and reactive power markets for the next twelve months. A normal distribution function is used for price forecasting. Two 3-bus and 14-bus test systems are used to demonstrate the capabilities of the proposed algorithm.

Backgrounds: Evidence indicating the association of cancers and chronic inflammations is increasing. The importance of urinary tract and sexually transmitted infections (UTIs and STIs) in the development of prostate cancer is still unclear. Chlamydia trachomatis (C. trachomatis) is one of the most important causes of UTIs and STIs. Here, a case-control study was performed on the Iranian population to assess the association between C. trachomatis and prostate cancer (PC).
Materials & Methods: Paraffin-embedded prostate tissue specimens collected from 62 PC and 62 PBH (benign prostate hyperplasia) (as controls) patients were screened to detect C. trachomatis 16srRNA gene using nested polymerase chain reaction (nested PCR) method. A p-value < .05 was interpreted as a remarkable difference using SPSS statistical software Ver. 16.
Findings: There was a significant difference regarding the prevalence of C. trachomatis (p < .001; OR=10.07; 95% CI [2.81-36.001]) between the PC (33.87%) and BPH (4.84%) samples. Furthermore, prostate-specific antigen (PSA) levels were statistically higher (p< .05) in C. trachomatis-positive patients than in patients with negative C. trachomatis.
Conclusion: It could be concluded that patients with a history of C. trachomatis infections are more likely to develope PC. Therefore, early diagnosis and treatment of C. trachomatis infection may help the prevention of PC. Moreover, nested PCR is a suitable method for C. trachomatis detection in paraffin-embedded prostate tissue specimens.

Academic lecturing has tuned into the major teaching method in higher education. Due to the excess of verbal and visual information presented in a lecture and the importance of some of these information in the final assessment of a course, an understanding of how unimportant information is marked in lectures is useful. The present investigation was an attempt to investigate how lecturers mark unimportant information in Persian academic lectures. More specifically, this study was aimed to investigate the discourse functions of markers of lesser importance. Based on a mixed-methods approach, markers of lesser importance were extracted from the transcripts of the 60 academic lectures of the Persian corpus of SOKHAN. The derived markers of lesser importance were then analyzed in terms of their discourse functions. Five discourse functions, including discourse organization, audience engagement, subject status, topic treatment, and relating to exam were found. In addition, topic treatment, followed by subject status, accounted for most of the discourse functions of the markers of lesser importance. Moreover, audience engagement, discourse organization, and relating to exam were found to be the least frequent discourse functions. On the whole, the findings suggested that marking lesser importance does not necessarily involves orientation to the audience or organizing the discourse into points and asides. Instead, marking lesser importance most often necessitates using expressions that explicitly or implicitly demarcate boundaries between what the lecturer wishes to talk about, does not intend to go through, or tends to cover briefly.

In the Holy Qur'an, there are verses which implicitly refer to the scientific subjects and scientific facts. Although the scientific aspects of these verses were unknown at the time of Revelation, the problem now and at this time is that the improper translation cannot reflect the scientific implications and references of the verses- their I’jaz or miraculous nature. The purpose of the present research is to study the English translations of the scientific verses to find if there is a meaningful relation between adequate/ acceptable and explanatory/ non-explanatory translations. To fulfill such end, first the scientific verses were selected based on four authentic exegeses. Next, four translations- Arberry, Irving, Yusuf ali and Saffarzadeh’s English translations- were selected. The aforementioned English translations were analyzed based on Toury’s initial norm of acceptibility and adequacy and an eclectic model of shift (Chesterman and Zahedi). The quality of translating the scientific implications were comparatively assessed in the four selected translations. The results show that Saffarzadeh has used more number of shifts and Yusuf ali, Irving and Arberry stand at the second, third and fourth positions. Based on Toury’s model, Saffarzadeh, Yusuf ali and Irving's translations are acceptable. These translations with more number of shifts, have translated the scientific implications in more number of verses than Arberry who has a more adequate translation. The more acceptable translations of the scientific verses are explanatory and transfer the scientific implications, qualitatively and quantitatively, more precisely and more properly.
