Background: The current narrative review aims to describe microbial agents causing pneumonia briefly. In addition, the ongoing review tries to introduce the diagnostic methods from biochemical to molecular tests used routinely and the promising molecular methods which will be used in near future.
Methods: PubMed was searched for all review and original articles related to the lung infection. Studies providing insights into clinical symptoms, microbiology, risk factors, and diagnosis were included.
Rasult & Conclusion: Untreated respiratory infections are one of the most common health care problems worldwide. We tried to provide a collective view of new aspects of bacteriology and diagnosis methodology of lung infection detection.

Translation is one of the ways through which ideology can be reproduced. Consequently, methods of discourse analysis can provide appropriate criteria for evaluating translators’ performance. Mojahedin Khalq who pay special attention to Nahj al-Balagha for representing their thought seem to transfer their institutional ideology while translating Imam Ali’s words. The study used a descriptive-analytical method and library resources to explore ideological viewpoint of Mojahedin while translating using Van Leeuwen’s approach. The approach is based on socio-semantic criteria and is divided generally into represention and deletion. The study showed that Mojahedin uses representing strategy more than deletion in their translation. In rendering fifty part of Nahj al-Balagha, activation, categorization, nomination, inclusion, exclusion, specification and deletion have been used. Amongst the elements, nomination, categorization and exclusion are the most frequent ones. Through representing social actors, Mojahedin have provided a special definition of revolutionary action. They then categorize the agents and invite people to them. Applying the elements have made Mojahedin create a version of Nahj al-Balagha that institutional discourse works instead of Alavi’s discourse (related to Imam Ali).

In the transition from the "speaking-listening" form of narrations to its "writing-reading" form, the risk of forgetting and all kinds of distortions caused by oral transmission began to decline; A matter that, although it was followed by a slight opposition at the beginning, but with the manifestation of its many merits, it met with public favor and following this all-encompassing tradition, hadith correspondences emerged. What makes this change somewhat problematic and creates a problem in trusting it is the void in the face of hadiths. The characteristic of the Arabic script in the classical period was not able to express all aspects of speech. Therefore, in some cases, multiple readings of hadith letters emerged; What in linguistics is called "reading deviations" that in some cases is different from the real meaning of Masoom (AS). The passage of time and distance from the atmosphere of hadith issuance fueled many readings; Therefore, it prompted the hadith scholars to look for solutions to overcome this problem. In this article, which is organized by descriptive and analytical method, an attempt has been made to present a model for a better reading of narrations by using both traditional and new methods. Going through the classic solutions such as paying attention to the "rules of Arabic literature", "famous reading" and "components of the sentence texture", referring to important criteria such as "finding the reading based on complementary relationships, intensity and contrast" and "analysis based on intertextual reference" gone.

Predicting the residual load-bearing capacity of damaged concrete-filled steel tube (CFST) columns exposed to fire, based on the effects of eccentricities, is a subject on which relatively little research has been done. This paper aims to present the results of a series of post-fire residual capacity tests for CFST columns with different cross sections (circular and square), under axial load, and different eccentricities in the event of a failure. In this experimental study, the influence of parameters such as cross-sectional shape, load eccentricity, slenderness and fire protective coating on the post-fire residual capacity of CFST sections was investigated. Based on the results of this study, the following conclusions were obtained in the scope of this research work:The results showed that eccentricity could be effective in reducing the residual capacity of the column, but the change in the amount of eccentricity cannot be as effective as reducing the residual capacity of the columns. The studies indicate that the residual capacity is significantly reduced by increasing the slenderness ratio. Therefore, in order to determine the residual capacity of the CFST columns under load eccentricity, a simplified equation for predicting the reduction factor was proposed, a comparison between the predicted and experimental results shows that there is a reasonably good agreement. The tests show that by increasing the temperature over a cross-section of CFST columns, the residual axial load capacity and the axial stiffness of the unprotected columns decreased significantly compared to the unheated columns. Comparison of the axial compressive capacity of CFST columns with square and circular have shown that for columns having the same concrete material, the circular column has slightly better structural post-fire behavior than the square column. To fire-protected sections, the effect of the cross-sectional shape on the residual strength is significant, relative to the unprotected sections is more. In fact, by comparing the temperature distribution on the surface of the circular and square sections, one can find that the maximum temperature distribution at the circular cross sections is less than the square cross sections. Therefore, with less degradation of the properties of the cross-sectional materials, the more residual load-bearing capacity is expected. Finally, based on the experimental results, the ability to predict the residual load-bearing capacity of the concrete-filled hollow tube columns after exposure to the ISO-834 standard fire as per the modified design method in Eurocode 4 for the fire and ambient conditions were evaluated. The investigation’s results showed that the simplified method of Eurocode 4, in the ambient temperature produced safe results for predicting residual resistance of CFST columns after fire exposure, under both concentric and eccentric loading conditions. This approach was considered as a conservative method, with the MPEs for concentric loads, as well as both concentric and eccentric loads as -5.51% and -3.06% lower than the prediction, respectively.
