Numerous hadiths about the preservation of the Qur'an, the value and status of preservers, which have encouraging themes and motivate believers to memorize and recite the Qur'anic verses and act on it, have been found in the Shi'a narrative Sources of infallible Shi'a. These narratives are collected in most narrative and commentary societies. But the authenticity of these narrations and therefore the validity of their texts are not the same, and no general verdict can be made. The present study uses a descriptive-analytical method, gathering information in a library-based manner, focusing solely on Shiite Sources, focusing its study on the most important hadith societies and looking briefly at the history of this science and the developments it has gone through., Has examined this, and shows that although some of the virtues of Preserving the Qur'an are correct in content or in the authenticity of their document, this is not a reason for their correctness and relies solely on the document or text for correction. A news does not mean that it is correct. Whether or not the correct document is incorporated into the correct text may either imply unacceptable meaning or disagree with texts that have stronger truth implications. There were such problems in the hadiths studied that made them inaccurate and difficult to accept. Of course, although most of the hadiths of the virtues of Preserving the Qur'an were weak, the Shi'a hadiths are legally bound to do so.

Protest uprising organized by tractor users in November 2016 on Eastern roadsides of Esfahan Province (IRAN) and their clash with police has been always a headline in newspapers. This phenomenon has been referred to as in only one of the numerous decisions affecting lifes of people radically. Why such decisions have been adopted? and why farmers have been faced so many crisis is the main questions posed by public. This Article seeks to study the nature and role of "public participation" in Preserving water Sources, as well as capacity of internal law and administrative system of Islamic Republic of Iran for promoting public participation in regulating and adoption of administrative decisions and their implementation for protection of environment in general and especially Preserving rare and vital water reSources. It seems that failure to respect the principle of public participation as one of the most important elements of governance is one of the important obstacles to realizing sustainable development. Participation of beneficiaries of a given decision in adapting public decisions, which directly affect their lives, through negotiation of people and union representatives, public survey, research and seeking non-governmental organizations' opinions not only can prevent adoption of arbitrary decisions and guarantees transparency of administrative decisions, it also promotes the culture of organizational transparency and contributes to the promotion of public culture and guarantee active participation of citizens in enforcement of decisions which protects rights of future generations and will guarantee sustainable development.

A new mathematical model for identifying pollution Sources in aquifers is presented. The model utilizes Lagrange Constrained Optimization Method (LCOM) and is capable to inversely solve unsteady fluid flow in saturated, heterogeneous, anisotropic confined and/or unconfined aquifers. Throughout the presented model, complete advection-dispersion equation, including the adsorption as well as retardation of contaminant, is considered. The well-known finite element method is used to discretize and solve the governing equations. The model verification is implemented using a hypothetical example. Also, the applicability of the developed code is illustrated by the real field problem of Ramhormoz aquifer in southwestern Iran.

Kardeh basin in Karst terrian situated in koppet dag zone. The lime and carbonate stones existing in karst forms have severely been broken up and there are crevices. As karst drainage system is highly sensitive to transference or arrival of any kind of pollutants, the existence of pollutants such as accumulation of garbage, animal excrements, the flow of setliements sewages to rivers, and trash accumulated by tourists can be potential pollutants for karst water Sources. Despite the fact that karst water supplies are used in the northern hills of Mashhad, there have not been protective measures, and karst water Sources lack management. It is, therefore; imperative to take protetive and managerial measure in order to control and safe guard water Sources. This article is aimed at dealing with karst characteristics and kardeh geomorpholical situation in relation to drainage sensitivity, and pollutant factors which have largely been increased in recent years. These factors have been identified and classified in the region, and their concentration situation is drawn in a map, which can be of importance for executives and planners.

In this study, 41 villages of Sabzevar were selected through cluster sampling. The chlorination quality drinking water in these rural areas was the main concern of the study. Also, the technicians knowledge concerning the proper ways of chlorination and chlorometery before and after a training course was evaluated. The results indicated that the present status of chlorination in rural areas was not satisfactory, and only in 10% of the samples, the remaining amount of chlorine after chlorometery could be considered optimal. As for the second concern of the study, the results revealed that the technicians were vaguely informed about the chlorination process; 40% of them could not even figure out the whole capacity of the reservoirs; 90% were unaware of the variable chlorine requirement. The remaining amount of chlorine after chlorination improved from 78% to 25% after the training course.

Background and Objective: Species of Aeromonas are gram negative, facultative anaerobic and opportunistic pathogens that are found in water system. In this study aimed was performed to determine of Aeromonas prevalence in water Sources and water supply Network in Qom.Materials and Methods: 150 samples of water Sources which were derived from 15 khordad barrier and other urban water Sources during 6 months from April 2009 to September 2009 by memberane filteration in particular environment with presence of amplicilin dextrin agar with vancomycin, were taken under evaluation.Results: Culture experiments and Determination of biochemical showed that only in 20 samples to 15 khordad barrier were positive for presumptive Areomonas with an average count 9 CFU/100ml water sample and the most of isolates belonged to the A. hydrophila, A. veronii biovar sobria and A. sobria species. Antibiotic Sensitivity test and tolerance evaluation of NaCl and cl presented some differences compared with E.coli and vibro that Aeromonas comparing with E.coli and vibro are less tolerant than NaCl (max 3%) and cl (max (37.5ppm) but more tolerant observed with antibiotics include ampicilin, erythromycin, amoxycilin, nalidixic acid, tetracycline and trimetoprim.Conclusion: The low abundance of bacteria in the water can be attributed to high chlorine residual (Average 8/0 ppm) and relatively high percentage of minerals and salt water network Qom.
