The Relationship between Consumption of Fast Food with Level of Serum Folat among Nursing Students of Islamic Azad University, Tehran Medical Sciences Branch in 2016

In recent decades, substantial increase in average weight of individuals has been seen in rich countries. Such changes are the result of significant changes in pattern of people’s lives. One of these issues is increasing levels in consumption of fast foods or processed foods. According to experts, the consumption of processed foods, because of having high-calories and trans-fatty acids, is fattening and harmful. In this study, the researchers after obtaining permission from the ethics committee and head of the School of Nursing, introduced themselves to nursing students then, samples were randomly selected among those who are eligible for the study. Before performing to complete the questionnaire and relevant experiments, testimonial were asked from the subjects. At the end of the study, results were suggested that, levels of Serum folate between males and females and also among married and single people were equivalent. Level of Serum folate among those students who usually have anemia in their families is significantly lower than those ones who have not anemia in their families (P = 0.003). There was a significant relationship between age and semester with levels of folate (P i.e. by increasing age and educational terms, levels of serum folate would be reduced. The level of serum folate among students who smoke is lesser than those do not (P = 0.001).

Two-dimensional Parameter Relationships for W UMa-type Systems Revisited

Reviewing the empirical and theoretical parameter relationships between various parameters is a good way to understand more about contact binary systems.In this investigation,two-dimensional(2D)relationships for P–MV(system),P–L1,2,M1,2–L1,2,and q–Lratiowere revisited.The sample used is related to 118 contact binary systems with an orbital period shorter than 0.6 days whose absolute parameters were estimated based on the Gaia Data Release 3 parallax.We reviewed previous studies on 2D relationships and updated six parameter relationships.Therefore,Markov chain Monte Carlo and Machine Learning methods were used,and the outcomes were compared.We selected 22 contact binary systems from eight previous studies for comparison,which had light curve solutions using spectroscopic data.The results show that the systems are in good agreement with the results of this study.

孔隙度对具有不均匀横截面的功能分级多孔梁的自由振动和屈曲行为的影响

本文旨在研究孔隙度对具有不均匀横截面的功能分级多孔梁的自由振动和屈曲行为的影响。一般认为材料的性能沿厚度方向变化,而梁的横截面沿其长度方向分布不均匀。三种不同的孔隙度分布包括对称分布、非对称分布和均匀分布。利用经典的梁理论和Hamilton原理推导出了问题的控制方程,并用微分求积法推导出公式。通过已知方法和分析解法对所得结果进行了验证。通过网格独立性研究,确定了最优离散化设置。利用详细的参数化分析研究了不同力学参数,包括孔隙率系数、长径比和变化截面对基频和临界屈曲载荷的影响。结果表明,材料孔隙率的增加会导致梁的屈曲能力显著降低。然而,梁的自由振动行为完全取决于其孔隙度模式。此外,孔隙呈对称分布的梁其屈曲能力和基频性能最好。

Seismic control of multi-degrees-of-freedom structures by vertical mass isolation method using MR dampers

Vertical mass isolation(VMI)is one of the novel methods for the seismic control of structures.In this method,the entire structure is assumed to consist of two mass and stiffness subsystems,and an isolated layer is located among them.In this study,the magnetorheological damper in three modes:passive-off,passive-on,and semi-active mode with variable voltage between zero and 9 volts was used as an isolated layer between two subsystems.Multi-degrees-of-freedom structures with 5,10,and 15 floors in two dimensions were examined under 11 pairs of near field earthquakes.On each level,the displacement of MR dampers was taken into account.The responses of maximum displacement,maximum inter-story drift,and maximum base shear in controlled and uncontrolled buildings were compared to assess the suggested approach for seismic control of the structures.According to the results,the semi-active control method can reduce the response by more than 12%compared to the uncontrolled mode in terms of maximum displacement of the mass subsystem of the structures.This method can reduce more than 16%and 20%of the responses compared to the uncontrolled mode in terms of maximum inter-story drift and base shear of the structure,respectively.

环氧树脂涂层中添加含铝复合粉增强碳钢基材的防腐性

采用电化学阻抗谱(EIS)和电位极化(Tafel)试验,研究了在环氧树脂涂层中添加含铝粉末以增强碳钢基材的防腐性,含铝粉末包括纯铝、Al/CNT、Al/Al_(2)O_(3)、Al/CNT/Al_(2)O_(3)。用球磨法合成含2 wt.%碳纳米管、2 wt.%氧化铝纳米颗粒的复合粉末,然后以1 wt.%的浓度加入到环氧树脂涂层中。结果表明,由于环氧树脂复合涂层的防护性能增强,从而提高了其耐腐蚀性。研究还发现,Al/CNT/Al_(2)O_(3)复合添加剂的保护性能比其他添加剂更显著,因为其颗粒尺寸的减小和具有某些形状的颗粒,进一步减少了腐蚀环境通过涂层渗透的路径,避免了金属基底/涂层界面可能发生的反应。EP-Al/CNT/Al_(2)O_(3)保持了一次时间常数特性,并在整个暴露时间内表现出最高的阻抗和最强的稳定性。这些添加剂的存在增强了涂层,从而改善了涂层的屏障性能。

Fatal cases in pediatric patients after post-exposure prophylaxis for rabies:A report of two cases

Rationale:Rabies is a zoonotic disease with a high mortality,primarily transmitted through the bite of infected mammals,particularly dogs and cats.Despite being a well-known disease since ancient times,it continues to cause a significant number of human deaths worldwide,with approximately 65000 fatalities reported annually.Patient concerns:We present two fatal cases of rabies in a 12-year-old immigrant boy and a 7-year-old boy.The first case was subject to a 24-hour delay in receiving appropriate medical attention and rabies preventive measures due to the lack of awareness among emergency hospital staff,leading to the administration of wound dressing only.The second case received timely rabies immunoglobulin administration;however,there was a 4-day delay in administering the fourth dose of the rabies vaccine,despite presenting evident symptoms of rabies.Diagnosis:Postmortem examination of brain samples from both patients confirmed the presence of rabies virus.Interventions:Post-exposure prophylaxis for rabies.Outcomes:Both patients were admitted to the hospital after the manifestation of rabies-related symptoms,with the 12-year-old child seeking medical care 47 days after the animal bite and the 7-year-old child seeking medical care 58 days after the exposure.Finally,the first patient died after 27 days and the second patient died after 40 days of hospitalization.Lessons:There is an urgent need for heightened awareness and education among both healthcare professionals and the public regarding the urgency of seeking immediate medical attention after potential rabies exposure.Timely recognition and initiation of post-exposure prophylaxis are pivotal in preventing the progression of the disease.Strengthening surveillance and reporting systems,coupled with continuous training for healthcare professionals,can contribute to early detection and management of rabies cases.

Reservoir Quality Controlling Factor of the Asmari Reservoir in an Oil Field in Dezful Embayment, SW Iran

The Asmari Formation Oligo-Miocene in age is one of the most important reservoir rocks in SW Iran and Zagros basin and composed of carbonate rocks and locally sandstones and evaporates. In this research, reservoir quality controlling factors have been investigated in a well in one of the oil fields in Dezful Embayment, SW Iran. Based on this research, depositional environment, diagenesis and fracturing have been affected on reservoir quality. 3 distinct depositional settings can be recognized in the studied interval including tidal flat, lagoon, and shoal. Among these depositional setting, shoal environment with ooid grainstone microfacies along with interparticle porosity shows good reservoir characteristics. Diagenetic processes also play an important role on reservoir quality;dolomitization and dissolution have positive effects on porosity and enhances reservoir quality, while cementation, anhydritization and compaction have negative effect on it. Fracturing is another important factor affected on the carbonate reservoirs especially in the Asmari Formation.

Comprehensive analysis of the role of ubiquitin-specific peptidases in colorectal cancer:A systematic review

BACKGROUND Colorectal cancer(CRC)is the third most frequent and the second most fatal cancer.The search for more effective drugs to treat this disease is ongoing.A better understanding of the mechanisms of CRC development and progression may reveal new therapeutic strategies.Ubiquitin-specific peptidases(USPs),the largest group of the deubiquitinase protein family,have long been implicated in various cancers.There have been numerous studies on the role of USPs in CRC;however,a comprehensive view of this role is lacking.AIM To provide a systematic review of the studies investigating the roles and functions of USPs in CRC.METHODS We systematically queried the MEDLINE(via PubMed),Scopus,and Web of Science databases.RESULTS Our study highlights the pivotal role of various USPs in several processes implicated in CRC:Regulation of the cell cycle,apoptosis,cancer stemness,epithelial–mesenchymal transition,metastasis,DNA repair,and drug resistance.The findings of this study suggest that USPs have great potential as drug targets and noninvasive biomarkers in CRC.The dysregulation of USPs in CRC contributes to drug resistance through multiple mechanisms.CONCLUSION Targeting specific USPs involved in drug resistance pathways could provide a novel therapeutic strategy for overcoming resistance to current treatment regimens in CRC.

New Systemic Order and Foreign Policy Strategies of the Islamic Republic of Iran in the Middle East

The international system has characteristics that have a direct influence on the foreign policy of the countries.Among these,the systemic cycle of power is one of the most conspicuous features of the global system and the regions that affect this issue.In this vein,the systemic order resulting from the cycle of power in the strategic policy-making circle of units can play a limiting role and influence the type of strategy and strategy.The Islamic Republic of Iran is also one of the units of international order;hence,it is not exceptional.Therefore,the purpose of this study is to examine the order of the Middle East and,accordingly,to determine the strategy of the Islamic Republic of Iran in that region.Accordingly,it assumes that the regional order in the Middle East puts defense strategies,especially deterrence and passive defense,at the forefront of the strategies of the Islamic Republic of Iran in the Middle East.So,the present paper,while explaining the order of the international system and the order of the Middle East region,designs the foreign policy strategies of the regions of the Islamic Republic of Iran.

Religious(Islamic)Culture Pluralism to Wittgenstein and Gadamer(A Comparative Study)

The current study aims to explain the fundamentals of religious pluralism in Wittgenstein later philosophy and Gadamer philosophical hermeneutics,specifically regarding culture.It,then,proposes the approach more suitable for the Islamic context.Having fulfilled such an objective,pluralism,concerning religious rituals,becomes accepted and cultural and religious interaction is realized without any relativism conclusion.Wittgenstein’s pluralism results in pure relativism.That is to say,in order to understand the rules of the language game and life style he mentions,one needs to be placed inside.However,it is a dialectical model that Gadamer philosophical hermeneutics leads to.Dialogue gives opportunity to cultural interaction and convergence,developing the religious culture.The latter is of more proximity to Islamic resources such as the Quran,proposing a religious culture transcending cultural,historical,and social limitations.All in all,the two significant features of Gadamer’s which Wittgenstein ignores are first,the interaction of religious pluralism encouraging the development of religious culture and second,reciprocal relation between culture and religion based on hermeneutics circle.

Relationship between effort-reward imbalance, job satisfaction, and intention to leave the profession among the medical staff of Qom University of Medical Sciences

Objective: The effort–reward imbalance(ERI) model claims that work that has the characteristics of high effort and low reward has a mutual defect between input and output and this imbalance may result in sustained and long-lasting results. This study aimed to investigate the relationship between the intention to leave the profession(ILP) and ERI and job satisfaction among the medical staff in Qom Province.Methods: A descriptive-correlative study was conducted on 202 medical staff in Qom Province based on random sampling in 2018. Demographics checklist, standard ILP, job satisfaction, and Siegrist’s ERI questionnaires were used for data collection. The chisquared test, independent t-test, and one-way Analyses of Variance(ANOVA) were used to analyze data.Results: The mean age of employees was 32.04 ± 7.9 years, and 165(87.1%) of the employees were women. The results showed that the medical staff was willing to leave their profession at a moderate level(40.7 ± 10.3). There was no significant relationship between demographics and ILP. Nevertheless, a significant and inverse relationship was observed between ERI(r:0.318, P < 0.01) and ILP(r: 0.197, P < 0.01). Leave the profession(LP) had a negative correlation with the dimensions of job descriptive index(JDI) such as job, manager, coworker and wage score(P < 0.01, r:-0.147, r:-0.262, r:-0.292, r:-0.271, r:-0.396).Conclusions: According to the results, managers need to make sure that their working staff is rewarded as they deserve. According to the results, managers need to ensure that the reward factor is observed for the staff, while an ERI imbalance may contribute to ILP of the staff. On the other hand, it leads to job satisfaction.

Finally, it was found that the specimen with 25 mm thickness and 30% alumina is optimum based on existing ballistic protection criteria.

Effect of whisker alignment on microstructure,mechanical and thermal properties of Mg-SiC_(w)/Cu composite fabricated by a combination of casting and severe plastic deformation(SPD)

In this research,microstructure evaluation,mechanical properties and thermal conductivity of the Mg-SiC_(w)/Cu composite with laminar structure were investigated.For this purpose,SiC whiskers were added to magnesium alloy by using stir-casting,then the Mg-SiC_(w)composite was bonded to copper layers by warm accumulative roll bonding(ARB).Based on the results of optical microscopy(OM)and scanning electron microscopy(SEM),SiC whiskers were well distributed in the magnesium matrix and they were aligned parallelly when the composites were plastically deformed at higher rolling passes.Furthermore,all layers remained continuous with localized necking sites.Also,no intermetallic compounds and phases were detected by XRD and EDS analyzes.Apart from the significant effect of severe plastic deformation on mechanical properties,the findings of mechanical tests point to the usefulness of reinforcements in improving up to 60%microhardness,Young’s modulus,yield,and up to 41%tensile strengths.Further,thermal conductivities of composites increased by adding reinforcement and above all by increasing the number of rolling passes.This growth is attributed to the higher thermal diffusivity of copper and whiskers as well as the increased number of conductive layers within composite.
