Accurate prediction of the minimum miscibility pressure (MMP) in a gas injection process is crucial to optimizing the management of gas injection projects. Because the experimental determination of MMP is very expensive and time-consuming, searching for a fast and robust mathematical determination of CO2-oil MMP is usually requested. This paper presents a new model based on a hybrid neural-genetic algorithm for predicting pure and Impure CO2-oil MMP. The CO2-oil MMP of a reservoir fluid was correlated with the reservoir temperature, the composition of the oil, and that of the solution gas. The developed model is able to reflect the impacts on the CO2–oil MMP of the molecular weight of the C5+ fraction, reservoir temperature, and solution gas in the oil. The validity of this new model was successfully approved by comparing the model results to the calculated results for the common pure and Impure CO2-oil MMP correlations. The new model yielded the accurate prediction of the experimental slim-tube CO2-oil MMP with the lowest mean absolute percentage error (MAPE), the standard deviation of error (SD), the root mean square error (RMSE), and the highest correlation coefficient among tested Impure and pure CO2-oil MMP correlations. The results demonstrate that the hybrid neural-genetic model can be applied successfully and provide high accuracy and reliability for MMP forecasting.

In this research, the production possibility of TiC-Al2O3 nanocomposite, as a useful ceramic from commercially pure TiO2, aluminum powder and carbon black has been investigated. Routile (TiO2) with carbon black and aluminum were placed in a high energy ball mill and sampled during different milling times. Then, the activated powders were synthesized at different temperatures in an atmosphere control tube furnace. Our results show that using this method has decreased the synthesizing temperature to 1000-1250oC by increasing the milling time. Also the width of X-ray patterns peaks, had made it apparent that, the size of produced TiC crystals was in order of nanometer. Furthermore it was detected that the lattice parameter deviated slightly from the standard size.

A metamorphic rock complex consists of slate, phyllite, micaschist and marble with NE-SW shistosity has cropped out in Neybaghi area in the NE of Myaneh. Impure marbles occur as thick and thin layers or massive bodies within the centeral area of this complex. Textural and mineralogical evidences, revealed two metamorphic stages. The early stage is testified by the minerals such as pyroxene (diopside), epidote (clinozoisite), amphibole 1 (edenite-pargasite) and plagioclase 1. The main stage have chlorite (clinochlore), phlogopite, amphibole 2 (tremolite) and plagioclase 2. P-T-XCO2 have been estimated for the early and main stage of metamorphism by computing nonideal and asymmetrical fugacity and activity and programing in THERMOCALC software for fluid and solid phases. The estimations give pressure, temperature and XCO2 of 9. 5Kbar, 660° C and 0. 35, whereas the main stage has been constrained at P=4. 2Kbar, T=510° C, XCO2=0. 4. The obtained P-T path shows that the Neybaghi marbles were formed under medium pressure condition and overprinted by a low pressure metamorphism. This type of P-T trend can be formed in collisional tectonic regime.

Background and Aim The widespread changes in societies and the diversification of human needs on the one hand, and the remarkable advances in medical sciences and chemistry, on the other hand, have led to the use of a large range of people from products whose raw materials have been considered ritually Impure in Islamic jurisprudence, including soaps made including soaps made from pig components. The question now is whether the changes made to these materials have changed their nature and eliminated their Impure? Materials and Methods The present research is based on descriptions and the analysis of the Islamic jurisprudential propositions and the library method to study the subject under discussion. Conclusion In response to this question, the Islamic schools have granted permission to transformation and therefore permit the use and sale of such soap. On the contrary, others believe that transformation is not certain or non-transformation is established. So the ritually Impure is still left. This group is divided into two categories, some of which do not allow the use of these types of products, but others, despite the Impure of use of these products, are entitled to use them for the needs of the people and in order to obviate the distress and constriction. It seems that among the existing narrative, the transformation and, consequently, the use and sale of products made from pig components, is more powerful than the existing ones.

Mean of irrigation water pure and Impure benefit for Yamchi canal were estimated 12669, 1515. 33 toman/m3 and for Ghoorichay were estimated 23988. 33 and 6523. 33 toman/m3, respectively.

Background: The instinct and natural tendency to eat food is an undeniable fact in human and all human beings, even the messengers of Allah and Infallible Imams (A. S) need it in order to keep themselves healthy. Methods: In this review study, using the teachings of the Holy Quran and other Islamic texts, the importance and role of food and healthy nutrition and its role in elevating human beings have been collected. Results: Formally, one of the influential factors in maintaining human’, s physical and mental health is his food and maintaining human health to preserve his real perfection and his unique position and dignity among creatures is mostly based on pure and healthy food. Allah has considered all human aspects in the Holy Quran, the ذook of human guidance and prosperity, and not neglecting, for example, his need of food, he has offered some guidance to meet this need. The Quran’, s criteria for choosing food are its lawfulness and purity. Conclusion: Considering the fact that “, pure”,means being pleasurable and good to eat, one of the interpretations offered in this article is that the man should avoid eating foods that are against human nature due to its being inconsistent with intact divine nature of human.

Increasing population and rapid industrialization and declining quality of water resources around the world have placed limitations on water use. Therefore, one of the solutions to fix this problem is the use of unconventional water and wastewater treatment and its use in various applications of drinking, agriculture, and health. Despite the fact that this issue has been studied in detail from a technical and engineering point of view, but unfortunately from a jurisprudential point of view, the method of purifying polluted water from wastewater has not been dealt with. One of the important issues that jurists have dealt with in the matter of the method of purification of polluted waters is whether the treated wastewater is purified after the decay of the three attributes (smell, taste, and flavor) as soon as it is connected to the Asem waters (water which is considered inherently pure, and therefore may be used to purify oneself. ) or not. There are two main views on this in jurisprudence. Some believe in the theory of connection and others believe that connection is not enough and mixing is a condition in addition to connection. In this paper, by explaining the jurisprudential background of the subject, the jurisprudential arguments of those who believe in the two theories of connection and mixing have been examined and Mukhtar's point of view has been explained in this regard. In this paper, Mukhtar believes in the theory of connection and the most important reason for proving this theory is Ibn Bazi's narrative from Imam Reza.

Background: Dysmenorrhea is a common problem especially in young women that can have adverse effects on quality of life.Aim: To investigate the effect of pure and Impure honey on severity of pain, amount of bleeding, and duration and interval of menstrual cycles in female students with primary dysmenorrhea.Method: The current study was a single-blind crossover design which was carried out on 60 female students with primary dysmenorrhea. After menstrual initiation, one group took pure honey until next menstrual period and after a 10 day wash-out period started to take Impure honey till the initiation of the subsequent menstrual cycle. Then dysmenorrhea was assessed using Visual Analoque Scale (VAS). The similar procedure was performed by Impure honey in the second group. The effects of pure and Impure honey were measured on severity of pain, amount of bleeding, duration and interval of menstrual periods in two groups. Data were analyzed Using SPSS software (V.14) by AONAVA test.Results: A significant difference was observed in the severity of pain following taking pure honey in group one (P=0.002). However, this difference was not significant in the this group following taking Impure honey (P=0.4). In the second group, similarly, significant difference was found in severity of pain after taking pure honey (P=0.004).Conclusion: Pure honey consumption in women, who suffer from primary dysmenorrhea, reduces significantly the severity of pain and amount of bleeding. It can be considered as an alternative treatment approach in affected women.

The current research applied four methods of supplementary pollination from male flowers of kiwifruit (cv. Tomori). These methods were open pollination, hand pollination, spray pollination with pure pollen, and spray pollination with Impure pollen, collected from the entrance of bee hives at the time of male kiwifruit flower opening and arranged in three replications in 2021. The fruits were harvestable after reaching the maturity stage (6.2 °Brix) and stored for 90 days at 0 °C. The results showed that kiwifruit decay (1.70%), weight loss (3.14%), total soluble solids (TSS) (149.62%), and TSS: titratable acidity (TA) ratio (TSS/TA) (333.04%) significantly (P≤0.01) increased during 90 days of cold storage. However, fruit firmness (38.24%), TA (42.10%), total chlorophyll (53.72%), carotenoid (18.65%), vitamin C (10.34%), flavonoid (12.87%), and antioxidant activity (13.29%) significantly decreased through storage time. Furthermore, total phenolic content (TPC) increased substantially after 30 days of cold storage but then decreased. Generally, fruits from vines sprayed with Impure pollen had higher firmness, bioactive compounds, and sensory attributes. They had lower decay and less weight loss after 90 days of cold storage. Overall, spraying kiwifruit vines with Impure pollen could be recommended as a practical supplementary pollination in kiwifruits, cv. Hayward, regarding postharvest quality maintenance.
