One of the methods to reduce damages caused by earthquakes is to concentrate damages in predetermined members. During an earthquake, these members minimize the damage caused to other members of the structure by absorbing a major part of the earthquake force. These members act like an electrical fuse that is blown under an unauthorized current of electricity and prevents damage to the wiring and electrical appliances used; Therefore, these members are called "structural fuse" and sometimes abbreviated as "fuse".EBFs are one of the most important resistant systems for bearing lateral loads. Researchers, paying attention to the simple replaceability approach, have introduced a shear fuse with joint connection in the connection area, which is named as a simple replaceable fuse. In this project, a series of numerical and laboratory researches are carried out in full scale, and this article refers to the comparison of design parameters.In this article, a brief explanation of Young's, Presley-Pauli's and energy methods is presented in each section, and then the design parameters are determined and compared. ETABS software was used for frame design and ABAQUS was used for numerical analysis. The comparison results show that the use of this fuse in EBFs has significantly improved the design parameters. Due to the simplicity of manufacturing and installing this fuse, using this method optimizes the design and saves the costs of construction and seismic improvement.

AbstractThe religion of Islam is superior to other civilizations in having the components of rationality, science and ethics that cause the rapid development and development of civilizations. The main question is, what is the score of the civilizing components of Islam compared to other civilizations? The findings of this research, using the descriptive and analytical method, show that Islamic civilization is based on belief in God and Islamic teachings, and by considering the necessities of happiness in this world and the hereafter, it brings good results to man and society; However, western civilization, with its focus on utilitarianism and separating reason and science from ethics, has put ethics in a position of destruction. Based on these components, Islamic civilization has the characteristics of collectivism and unification, inclusive time and universality, seeking justice, Mahdism and complete leadership over the world.The purpose of this article is to express the duties of believers for the construction of a new Islamic civilization, from which we can expect relief and groundwork, all-round cooperation for the construction of Islamic civilization, Jihad of explanation, perseverance and martyrdom. He pointed in the way of God.

Qur’an and Hadith are the two main sources for knowing the Islamic market. After the victory of the Islamic revolution, the Islamic world sought to know the Islamic market, as one of the achievements of the Islamic revolution, in order to get acquainted with the efficient strategies of the Islamic economic system. In this intra-religious research, an attempt has been made to infer, describe and analyze the characteristics of the Islamic market from religious texts. Because the religious indicators of the market are in two parts, positive and negative, therefore, in this research, Qur’anic and hadith findings about the Islamic market have been extracted and recorded in two parts, dos and don'ts. In the positive indicators, halal sustenance and legitimate business, knowing of Sharī'ah rulings and business jurisprudence, remembrance of Allah, prayer, perfection, solidity of goods, transparency and honesty have been examined and the list of other indicators has been reported in nineteen axes. In the negative indicators, damaging and underselling and non-transparency were investigated and other indicators were listed in fifteen axes. In addition to the indicators, the lifestyle of Imam Ali (as) is also presented in the affairs of the market. The researcher has tried to describe and analyze the sacred religious texts with economic words such as market, halal and haram sustenance, halal and haram, trade, buying and selling, sustenance, causing harm, underselling, weighing, scales, non-transparency and their types of marketing.

Given the brittle behavior and low flexibility of unreinforced masonry walls, using flexible fiber-reinforced concretes, such as engineered cementitious composites (ECCs), to retrofit them is of great importance. In this regard, the performance of these materials (as a reinforcement layer of unreinforced masonry walls) in improving their behavior (flexibility and strength) against dynamic loads, especially impact loads, should be taken into account. The present study evaluates and compares the vertical middle displacement, energy, and distribution of plastic strains in unreinforced masonry materials, under two conditions, i.e., non-retrofitted and retrofitted with a one-side cover (in the lower surface of the specimen) or two-side cover of ECC layers under dynamic impact loading, through nonlinear dynamic impact analysis. The ECC reinforcement layers in two-side covers were investigated by changing their location (in the middle or edges of the lower surfaces of the specimen), connection type (disconnection or full connection) of the one-side cover of the bottom of the specimen with the ECC reinforcement layer and elastic modulus (from 15 GPa to 22.5 GPa). The retrofitting of the unreinforced masonry materials with ECC layers (especially with two-side cover) improved their behavior against out-plane impact loads, dissipated energy, and reduced the plastic strains and cracks.

One of the divisions proposed in connection with the narration is its division into iftā’ī and ta’līmī. Iftā’ī narration refers to the narration that only expresses the current duty of the questioner. On the other hand, there are ta’līmī traditions that express the general ruling for the purpose of training jurists (fuqahā) and master jurists (mujtahidīn). One of the most important issues regarding this division is to provide characteristics that can be used to distinguish between taʻlīmī and iftā’ī narratives. By using the descriptive-analytical method and through sampling in the book Tahdhīb al-Aḥkām of Shaykh al-Ṭūsī, this study has tried to present the most important characteristics of knowing these two categories of narrations. This study has concluded that the four main characteristics of the narrator’s attributes, the conditions of the time of issuing the narration, the content of the narration, and the use of the ta’līm style, are the most important characteristics for understanding ta’līmī narrations. It is worth noting that all these characteristics are used as a witness for being ta’līmī and it is necessary for a person to be sure of these things in order to be able to apply the rulings of ta’līmī narrations.

In this study, effect of poly vinyl alcohol (PVA) and poly propylene (PP) fiber on epoxy resin-based concrete in terms of compressive, flexural, tensile strength and deformation has been investigated. In addition, scanning electron microscope (SEM) analyses were conducted on samples. Four groups of polymer concrete with 12% epoxy resin and fiber dosage of 0.5, 1, 2 and 2,5 % were prepared for both PVA and PP fiber. The fiber length was 12 mm. Cube and prism samples with 50 mm and 50x50x300 mm dimensions were prepared and tested for compressive strength and tensile strength/ deformation at 1, 7 and 28 days. Results showed that by increase of PP dosage, compressive and tensile strength increased noticeably compared to the control sample. However, for samples containing PVA, opposite trend has been observed. Therefore, the optimum dosage of PP and PVA fiber in fiber reinforced epoxy resin-based concrete is 2.5 and 0.5% respectively. The increase in compressive and flexural strength for 0.5, 1, 2 and 2.5% PP fiber was 4.38%, 5.3%, 4.9% and 5.5% compared to the control sample, respectively. The SEM analysis showed good bonding of both PP and PVA fiber to the polymer matrix. The PP fiber had better dispersion which could be the primary factor for better physical performance.

In Islamic jurisprudence, there is a very important issue under the title of Islamic government, which is the distinguishing feature of the rules of Islamic law compared to other religions. In fact, in the teachings and opinions of Islamic jurists, the concept of political power has been recognized through the recognition of Islamic government. In the meantime, Shia jurists refrained from dealing with the issue of political power as one of the basic and main issues of Shia jurisprudence due to the specific socio-political conditions from the time of the beginning of Islam until the establishment of the first Shia governments. But after the formation of Shiite governments, the issue of political power became one of the most important issues in the field of political jurisprudence. The purpose of the current research, which was collected with descriptive-analytical method and library tools, is to analyze and evaluate the concept of political power in the thought of Shiite jurists. In the end, in light of the evolution of Shia thoughts, it is witnessed that in Shia political jurisprudence, given the openness of ijtihad from its outset to the present time, there have always been new mechanisms for ruling in the society, so that after the Infallible (pbuh), depending on historical conditions, other jurists and Islamic scholars have proposed various theories about political power.

The text of the question of Imam Ali (peace be upon him) and the answer of the Prophet of God (peace be upon him) on the subject of jihad and martyrdom is found in a hadith of Imam Reza (peace be upon him). This hadith is mentioned for the first time in the book of Sahifa al-Reza, peace be upon him, that it is one of the principles of Arbamah, and its validity is stated in this article, and the personality of the narrator of the hadith is also examined as a man (issue). This research is dedicated to the description and analysis of the document and the text and the meaning of the same hadith (method); Islamic thought, Islamic awakening, Islamic aspiration, jihad, resistance and martyrdom are all at the same time, and martyrdom is the highest virtue in the world. This article is dedicated to explaining this peak of goodness. In this hadith of Razavi, peace be upon him, the situation of the Mujahideen from the first step has been shown in detail in three parts, from jihad to martyrdom, from martyrdom to the resurrection, and from the resurrection to eternity. It is connected until after the martyrdom, which is not in any other hadith (findings);

The Holy Qur’an, with its characteristics of universality, comprehensiveness and immortality, has provided an accurate and logical picture of the personality and dimensions of human existence. (Say, ‘Everyone acts according to his character. Your Lord knows best who is better guided with regard to the way) (Asra/ 84). In addition to the nature of seeking God, man with a sound heart, intellect and wisdom can achieve the goal of creation, the status of worship. The righteous worshipers of God have followed the path of servitude by purifying their souls, and by benefiting from divine knowledge and protection from error and sin, they have also taken on the responsibility of guiding society. The Holy Qur’an describes the personality of Ibadullah (sincere [and devoted] Servants of Allah) with characteristics such as sincerity, gratitude, protection from the temptation of Satan, and so on. The present study has examined the personality of Ibadullah (sincere [and devoted] Servants of Allah) from the perspective of the verses of the Holy Quran by descriptive and analytical library method, using existing books, articles and databases. From the results of achieving the individual and social characteristics of the worship of God, we can point to the recognition of the presence of the Imam Mahdi in the present age. Therefore, awareness and effort to obtain the necessary preparation for the emergence of the reformer and savior of humanity and the formation of a good life, is necessary and is considered one of the highest acts of worship.

Volvovaginal candidiasis (VVC) is a common fungal infection in women. The production of extracellular enzymes act as virulence factors in the pathogenesis of Candida species. The aim of this study was to evaluate the activity of phospholipase, proteinase and to investigate the distribution pattern of Sap5 and PLB1 genes in Candida isolates isolated from women with VVC. 

This descriptive cross-sectional study was performed on 135 vaginal swabs of women with suspected VVC. Candida species were identified by PCR-RFLP and the activity of hydrolytic enzymes and frequency analysis of SAP5 and PLB1 genes were evaluated.

The results showed that C. albicans has the highest frequency (67%). In total, 80% of the studied isolates have proteolytic activity and 73% have phospholipase activity. Furthermore, the frequencies of PLB1 and SAP5 genes among Candida species were reported 95.7% and 91.4%, respectively. Simultaneous presence of SAP5 and PLB1 genes was observed in 87% of the isolates.

The results of present study showed the importance of molecular epidemiological studies and understanding the role of virulence factors associated with extracellular enzymes in the pathogenesis of Candida strains.

The purpose of the present study is to display “the doctrine of intellectual freedom” based on religious references. By searching and analyzing the term “Horriyat” in Islamic traditions, it was determined that it is possible to set the doctrine of intellectual freedom to answer all likely questions in this regard. According to the content of Ahādith from Ahl al-Bayt, human freedom and Horriyat is not contractual or presented by mankind but it just relies on the divine “command” as God has created humans and bestowed them the gift of freedom and the free living. Reflection upon the Ahādith of Imams about freedom proved that the cause and philosophy of freedom is the spiritual evolution and praying to God; and that the highest prayer belongs to the free men and women. As for the essence of freedom and the truth of liberty, there are many positive and negative features that all have been mentioned in the Ahādith of Ahl al-Bayt. It is evident that in recognition of freedom and people’s duty about that and free people, the underlying causes and significance of knowing and seeking freedom and having Horriyat is embedded.

“Appealing” to God’s friends (Avlia-allah) is Shrek (ascribing partner to Allah)! Why do you go to the Imams pilgrimage? These are some questions every day are being asked from Shi’a. But by whom? Why? Such suspicions have been raised by the enemies of religion and by the use of ignorant religionists such as Wahhabism and the intent to eradicate pure Islam. Their suspicion is based on two things: 1) It is wrong to put someone in the middle between yourself and God. 2) If it is possible to appeal to the living person, it is not possible to appeal to the dead. Replying to the first question: The Qur’an itself commands the use of a means to draw near to the Almighty God. It is used the word “means” generally and mentioned examples of prophets and their followers who used the appeal. Like the descendants of Prophet Jacob who made the Father forgive their sins. Replying to the second question: The friends of God are not dead, because the Qur’an states that martyrs are alive; and appealing to the God’s friends is appealing to the living people, not dead. The appealing is elixir, making the world and the hereafter of humans in the most perfect way. The appealing is worthless, and therefore has been attacked by enemies and opponents. And yet, if something was not worthwhile or influential, it would not have received the attention of both friends and foes.

"Relationship" with Imam Mahdi (a) and "Greeting" are two pillars in the subject of Mahdaviat. In this research, the meaning and application of the sentence "Rabeto" from verse 200 of Surah Al-Baqarah and the sentence "Baqiyatullah" from verse 86 of Surah Hood are explained by referring to interpretive hadiths in a descriptive-analytical method. The issue of research is how to Relationship with the Guardian of the Age (PBUH) through "Greeting" in the age of absence and presence. The purpose of this research is traditional commentary of "Rabeto" and "Baqiyatullah" in relation to each other. Till now, no such Qur'anic and traditional research has been conducted in connection with these two important issues of components of the principle of Islamic Mahdaviat. The discovery of the meaning of "Rabeto" and "the rest of God" in the Qur'an and how to "Greeting "to Imam Mahdi (as) by defining the Ahl al-Bayt (as) is the Innovation of this research. By examining the lexicon and verse studies with the help of tradition, it became clear that the meaning of "Rabeto" in Surah Al-Imran today is the connection and Relationship with Imam Montazer (as) and the meaning of "the rest of God" in Surah Hood is also Imam Mahdi (as). And the text which narrated for greeting to Qaeme Ale-Muhammad (PBUH) in both historical periods, in the era of absence and in the era of Appearance, is "Peace be upon you oh the rest of God on earth". It is worth mentioning that there are other greetings to relationship with Imam Mahdi (as) that should be searched in related sources.

The independence of judges in arbitration is an important process that is mentioned in the one hundred and fifty-sixth article of the Constitution. The main issue of this research is the moral solution of the false brothers of independence and despotism in judgment. Judges sometimes become confused between the two when making decisions and sentencing, which can only be resolved by recognizing their nature and criteria for differentiation. The solution to this moral challenge can be proposed in other areas as well, but according to the teachings of the Holy Koran and the narrations of the Ahl al-Bait (AS), the “cognitive” area (data generation and dependent data processing) is of fundamental importance. The works written in this field have dealt with the independence of the judge, judicial justice, judicial etiquette or political despotism, which lack recognition and study of the two, morally speaking. This study, as far as possible, has expressed the criteria, signs and examples of independence and despotism in this field so that judges in the situation have the ability to move out of this astonishment and moral confusion.

Judges sometimes make the distinction between independence and despotism when deciding on a sentence that can only be distinguished by understanding its nature and criteria. All the written works in this field dealt with the judge's independence from legal, jurisprudential and political perspectives and lacked any insight into their understanding. It was possible to solve such a problem in a network of different domains. The purpose of this study is to solve these two ethical paths through a religious domain based on insight.

The research method in this study is analytical and applied based on valid library resources.

Extraction of four criteria: "correctness of attitude towards the origin of existence", "recognition of analytical capacities and emotional limitations", "real recognition of the origins of spiritual knowledge and its attachment", "consideration of assignment, formulation and developmental judgment" In addition to the judiciary, it was also essential for individual and organizational decision-making.

This study stated the criteria, indicators and instances of independence and despotism with regard to the field of vision, so that the referees in the situations faced can be able to depart from these two ethical paths.

The main source for the conceptualization and application of ethics is the hadiths of the Prophet and the Imams (as). In this research, an attempt has been made to deduce the main issues regarding the concept and application of ethics through hadith studies. Examining the cases of symmetry of creation with the conquest of Khaa and creation with the addition of Khaa in the text of hadiths helps to understand the truth of morality. In this research, the answers to some ethical questions have been clarified from the conceptual analysis and example of this simultaneous repetition and adaptation. Examples of good morals are many and endless. With hadith studies, different types of good morals were extracted and the concept and examples of good morals were shown to researchers in both specific and general meanings. The purpose is to deduce the concept of good character and its types from the hadiths. This research has been done by descriptive-analytical method with hadith studies and reference to reliable sources in the library.

slamic Awakening is a return to Islam and the Qur'an and the Sunnah of the Prophet and the Ahl al-Bayt (as). The Islamic Awakening must be properly defined and find the empowering factors of it to be operating. The empowering factors of the Islamic Awakening must be found and implemented. Undoubtedly, the Qur'an and the Sunnah of the Infallibles (peace be upon them), and the history of Islam in Iran, and the political movement and thought of Imam Khomeini(ra) and his students and companions are the creators of the spirit and content of the Constitution of the Islamic Republic of Iran. This great covenant between the Imam and the people of Iran is a powerful source of inspirational for the "Islamic Awakening". Introduction, chapters and principles of the Constitution of the Islamic Republic of Iran is the National Covenant of Iranians and the result of the ijtihad of Velayat-e-Faqih and the Imitation references, mujtahids, jurists and lawyers. And within it, the mission and duties of the Islamic system, diplomacy and political behavior of the Islamic Revolution and foreign policy and the goals of the Islamic Republic of Iran and the strategies for exporting the revolution and the duties of the army, IRGC, government and nation are clearly stated. Therefore, the Constitution of the Islamic Republic of Iran has explained the legal requirements of the government and the nation for Islamic awakening and foreign policy based on the wisdom, dignity, expediency and authority of the Muslims of the world.

Many research Findings emphasis that investors in their investments decisions will prefer smooth profit with low fluctuation. In this regards managers will try to manage the benefit and its growth. Managers either with tampering the information's for the sake of their benefit or transferring and reporting confidential information about management. The study tries to investigate the effect of benefit management by using negative correlation between the optional obligatory items change and anticipated changes of benefit. The essential performance indicators which include cash flow fund, earning per share, liability items and dividend yield have been considered and these components are considered as efficiency indicators in this research.The statistical population included all the listed companies in securities bourse in Tehran during 1384-1392. Using systematic call-off sampling method 89 companies was selected as the sample size. The results showed that there was a significant relationship between the profit management and companies performance. The profit management is also effective in forecasting future cash fund, in forcing solidarity between running and future yield.

According to Islamic texts and the teachings and forecasts, Imam Mahdi and his appearance coincides with the return of the Jesus Christ. According to hadiths of Ahlul bait and commentator's views, two verses in the Quran are related with the advent of Imam Mahdi and the descent of Jesus, son of Maryam (peace be upon her) and the two are related work. So, the revelation of Christ in the era of Hazrat Imam Mahdi to help are final and took out both of Ashrat and there is no opposition between the Mahdi and Messiah, but in either way agree, and the work will be completed. In this paper, by referring to authentic Islamic sources and studies on Mahdaviyyat a descriptive study investigated status and quality of interaction promised to the Muslim world, Imam Mahdi, through Messiah of Christianity, Jesus. Jesus descends from heaven at the time of reappearance of Imam Mahdi and pledges allegiance to Imam Mahdi and helps and keeps companionship with him and combats historical biases and distortions of Christianity and brings Christ and His followers in prayer, following Imam Mahdi and guides Christians toward Islam and fight the enemies of Imam Mahdi. This is, by far a positive interaction and cooperative account of Christ and Mahdi relationship.

The purpose of this article is to analysis the concept of greed and explain examples. In this research with the scientific authority of Imam Reza (AS) sayings, concept and extentions of greed and its kinds is inferred from the Razavi texts. Main problem of this paper is discovery of Functions and instances of “holy greed” in expressing OF ALIME – ALE- Muhammad (PBUH). Research Method is Descriptive Analytical Basically and by study of traditions of Razavi(AS) The fact of praised greed and extentions and its samples will be explain. Studies and examining the sayings of Imam Reza (AS) for “greed ology” showed that in some cases, had commanded to be greedy. Imam Reza (AS) with the formula of command “EHRESOO” in a comprehensive tradition have taught, three headlines of “praised greed” to the whole world. Greed on “to grant needs of believers” and “to give happiness to believers” and” to fend off sadness from believers” has been command of Imam Reza (AS). In the paper with Contextual study of Hadith of Imam Reza (AS) and other infallible Imams (AS) is inferred and explained.

Salman al-Farsi was the first Persian to convert to Islam. He was raised as a Zoroastrian, then converted to Christianity, and then after meeting the Prophet Muhammad, he converted to Islam, and played a fundamental role in promoting Muslim unity. After becoming Muslim, Salman grew under the guidance of the Prophet and Imam Ali until he reached the peak of faith and was the best of the Ahlul Bayt’s companions. This article delves into the personality, character, and faith of Salman as seen in the traditions of the Ahlul Bayt, as well as several Sunni sources.

Arbaeen pilgrimage is the largest gathering of people around the world and the biggest religious festival of Shiites which has an important role in demonstrating the power of Shiites and expanding the objectives of Shiite Islam among the nations; Therefore, enemies of Shiites from all groups and religious and political schools attempt, by creating confusion and doubt and calling this political-worshiping festival as heresy, discourage Shiites from doing it. Providing documents and accurate, consistent and reliable scientific evidence in proving the authenticity and legitimacy of this spiritual festival can not only reveal the deception and tricks of enemies of Shiites and Ahlul-Bayt (AS), bur also pave the way for holding this fathering in a more elegant way among the great population of Imam Hussain’s fans. This article, by analytical-descriptive method, has tried to provide documents and evidence from traditions, history and lifestyle of Imams (AS) so that lovers of Imam Hussain and Ahlul-Bayt can respond to conspiracies of malevolent enemies. In this regard, this article not also provides documents and historical and Hadith evidence, but also mentions narrative documents of Arbaeen pilgrimage and part of the text, then to Jaber Ibn Abdullah Ansari’s role in the first Arbaeen pilgrimage and in the end, has provided the readers with results of present research.

Following the news of the martyrdom of Imam Musa al-Kazim (AS), Shia community was faced four different reactions: The first group confirmed the news and believed in the Imamate of Imam Ali ibn Mua al-Reza (AS). The Second group denied the martyrdom of Imam; the third group was told that the Imam is dead but would return; and the fourth group remained skeptical. The similarities between the second and third groups are to end the chain of Imamate by Imam Kazim (AS), belief in his being "Mahdi" and belief in the Imam's return. The second and the third group in the history of the sect are known Vaqefeh. Rise of Vaqefeh is due to two reasons: the first one is due to a misunderstanding of the political activities of Imam Kazim (AS) and contradictory news about his martyrdom and the second is due to the greedy companions of Imam. Imam Ali ibn Musa al-Reza (AS) coped with Vaqefeh through: awareness to the community, social and ideological struggle, disclosure; and paranormal habits. The leading article explores these practices with the help of authentic sources of cultology and narrative books

Textile dyes are the largest organic compounds associated with some problems for the environment. Advanced oxidation process is the most effective method for dye removal from wastewater.
The aim of this study was to investigate the efficiency of the photo Fenton process for decolorization of direct red 81 (DR 81) dye, and to determine the optimal process conditions.
This is a cross-sectional study conducted on a laboratory scale. The effective parameters in the photo Fenton process include pH, ferrous sulfate heptahydrate concentration, hydrogen peroxide concentration, initial dye concentration and reaction time. These parameters were studied, and finally analyzed using the Excel software.
According to the obtained results, maximum removal efficiency was 98.1% at pH = 3, concentration of Fe (II) was 10 mg/L, hydrogen peroxide concentration was 50 mg/L, initial concentration of dye was 100 mg/L, and reaction time was 120 minutes. Results showed that increasing the concentration of Fe (II), H2O2 and the initial concentration of dye to a certain extent resulted in increasing removal efficiency, then by increasing the concentrations of these parameters, removal efficiency decreased. Results also indicated that increasing a reaction time resulted in increasing removal efficiency.
The photo Fenton method with optimized parameters can be used to conduct high efficiency dye removal in a short period of time and this process is based on hydroxyl radical formation.

Diabetic patients are more susceptible to oral Candidiasis infection than non-diabetic groups due to the factors promoting oral Candida in carriage. Several factors are the dilative of the colonization of Candida species in the oral cavity, such as xerostomia, which reduce the salivary flow and salivary pH disorder.
Samples from saliva and mouth lesions were collected from 106 individuals from June 2014 to September 2015, which were consisted of two groups: Diabetic patients (n=58) and non-diabetic (n=48) as the control group. The objective of this study was to evaluate the presence and identification of candida spp. with CHROMagar candida and PCR-RFLP using the restriction enzymes HinfI and MspI,
In this study, oral candidiasis frequency in diabetic patients in relation to non-diabetic ones was more due to factors that promote oral Candida flora in diabetic patients.
The frequency of candida species in diabetic patients group was Candida albicans (36.2%), C.krusei (10.4%) C.glabrata (5.1%), C.tropcalis(3.4%), respectively. Likewise, C.albicans was the most frequent species (27%) in oral non-diabetic individuals.
Nutritional disorders, such as diabetes mellitus are considered the important predisposing factor for oral candidiasis. The objective of the current study is determining the distribution of candidal species in the oral cavity with CHROM agar candida and PCR-RFLP.In order to evaluate the amount of yeasts colonized in diabetic patients compared with non-diabetic individuals for improving patient treatment outcomes and reducing healthcare costs.
