The Iranian Government’s Approach towards the Use of Hijab

This study has considered the clothing culture of Iranian female and through the first part it will explain the life line of hijab and any possible connection between this Islamic symbol and Iranian dressing culture. In case of declaring the government roles in dressing culture, a considerable attention was paid to the history of Iranian monarchy from Achaemenid up to Qajar and Pahlavi. During the research, the female’s dressing, position in monarchy, aristocracy and society, invading Iran by Islam, adapting and converting the Islamic culture to the Iranian version, were all described in details. The second part of this study is more focused on political aspect of hijab, the history of feminism, the debate about dress code, motherhood and morality, modernization, pre-Islamic revolution atmosphere, Reza Shah Pahlavi’s compulsory unveiling and inspiration of global modernization. The last part of this study is particularly dealing with Islamic revolution and post-revolution era when the hijab suddenly became a matter of state’s concern and women were forced again to cover themselves in public. The study also points out that Iran always understood that clothing is a powerful manifestation of political thought and in turn are evidence that the nation adhere to state ideology. At the end the researcher explains her points of view and emphasises on political perspective of hijab through the conclusion. The main methodological approach of this study is content analysis of documents, books, articles and other materials which conclude the fact that the governments and states attends to instructing the people’s privacy and establishing codes for everything even dressing is a dedication of state’s interference. The researcher has no doubt and proves that although the Iranian dressing culture might look similar to the hijab, there is no evidence of existing a clothing code of conduct in history which could be referred to hijab or any other Islamic symbol of female appearance

Resource allocation in cloud computing using advanced imperialist competitive algorithm

Cloud computing makes possible free access to computing resources and high-level services for performing complex calculations and mass storage of information on the Internet. Resource management is one of the most important tasks of cloud providers, which is known as resource allocation. Heterogeneous resources and diverse requests at different time intervals makes it difficult to solve resources allocation problems and is considered as a NP-hard problem. Providing an efficient algorithm for resources allocation to satisfy the cloud providers and customers has always attracted much attention of researchers. Heuristic methods have always introduced as a good model for problem solving. However, most algorithms suffer from early convergence. This paper proposes a new approach based on imperialist competitive algorithm (ICA) which emphasizes the optimization of resource allocation in reducing time, cost and energy consumption. The proposed approach has been able to improve the early convergence of colonial competition algorithm by combining with the Tabu Search Algorithm to achieve an optimal solution at an acceptable time. The evaluated results show more efficiency performance than several relevant effective algorithms

Review on the Energy Storage Technologies with the Focus on Multi-Energy Systems

Energy storage is an important element of an energy system. In the power system, energy storage can be defined as a component that can be employed to generate a form of energy or utilize previously stored energy at different locations or times when it is required. Energy storage can enhance the stability of the grid, increase the reliability and efficiency of integrated systems that include renewable energy resources, and can also reduce emissions. A diverse set of storage technologies are currently utilized for the energy storage systems (ESSs) in a varied set of projects. This chapter provides information about the current ESS projects around the world and emphasizes the leading countries that are developing the applications of ESSs. The main categories of ESSs are explained in this chapter as follows: electrochemical, electromechanical, electromagnetic, and thermal storage. Moreover, the energy storage technologies are utilized in power grids for various reasons such as electricity supply capacity, electric energy time-shifting, on-site power, electric supply reserve capacity, frequency regulation, voltage support, and electricity bill management. Additionally, by integrating the various energy forms and developing the concept of multi-energy systems, ESSs become a fundamental component for the efficient operation of multi-energy systems. The main role of ESSs in multi-energy systems is to compensate for the fluctuations in power output from renewable energy resources. Moreover, the performance of the multi-energy system increases when it got integrated with an ESS. In this chapter, the applied ESS technologies in the context of the multi-energy systems are presented and explained.©2022 Wiley-VCH Verlag.

Optimal Operation of Solar Powered Electric Vehicle Parking Lots Considering Different Photovoltaic Technologies

The performance of electric vehicles and their abilities to reduce fossil fuel consumption and air pollution on one hand and the use of photovoltaic (PV) panels in energy production, on the other hand, has encouraged parking lot operators (PLO) to participate in the energy market to gain more profit. However, there are several challenges such as different technologies of photovoltaic panels that make the problem complex in terms of installation cost, efficiency, available output power and dependency on environmental temperature. Therefore, the aim of this study is to maximize the PLO’s operational profit under the time of use energy pricing scheme by investigating the effects of different PV panel technologies on energy production and finding the best strategy for optimal operation of PVs and electric vehicle (EV) parking lots which is achieved by means of market and EV owners’ interaction. For the accurate investigation, four different PV panel technologies are considered in different seasons, with significant differences in daylight times, in Helsinki, Finland.© 2021 by the authors.

False-positive defects on exercise 99mTc-sestamibi SPECT imaging, but not on dipyridamole 99mTc-sestamibi SPECT imaging, in a patient with right bundle branch block (RBBB)

False-positive findings with myocardial perfusion imaging (MPI)have frequently been identified in the presence of left bundlebranch block (LBBB) and tend to lower the accuracy of MPI inindividuals with normal coronary angiographs. Pharmacologicstress is recognized as the preferred method for MPI in patientswith LBBB. In contrast, very few studies have evaluated the effectof right bundle branch block (RBBB) on MPI, and there isno consensus regarding the selection of pharmacologic versusexercise stress during MPI for the RBBB patient. In this study,we present a 45-year-old man with RBBB, who has a normal coronary artery angiography, but who showed abnormal myocardialperfusion with exercise MPI, and normal perfusion ondipyridamole MPI. The aim of the study is to stimulate awarenessthat the stress method selected for patients with RBBB canpotentially interfere with the accuracy of the data

The association of increased stomach wall radiotracer uptake with prolonged use of Omeprazole capsules on myocardial perfusion imaging (MPI) using 99mTc-sestamibi SPECT

Myocardial perfusion imaging (MPI) is widely used in routinepractice for diagnosis and risk stratification of coronary arterydisease (CAD). Intense curvilinear activity in the stomach wallof a patient was seen on MPI raw data. This phenomenon was completely dissimilar to the familiar intraluminal gastricreflux of sestamibi. This observed activity could have resultedin false-positive or false-negative artifacts — and inaccurate diagnosis — of the inferior wall of the left ventricle after MPI processing. On further exploration, the current researchers found that the patient had a history of 10-year Omeprazole capsule consumption. The authors present this infrequent case of intense stomach uptake to stress the related clinical and diagnostic implications with the aim to stimulate acute awareness of possible, unexpected infringements on image quality that could potentially interfere with accurate interpretation of the data

Bone mineral density is not related to angiographically diagnosed coronary artery disease

Based on data, there may exist an association between low bone mineral density (BMD) and atherosclerosis. Thisstudy aimed to investigate the association between BMD and coronary artery disease (CAD). In this study the possible association of BMD with CAD in 65 men with CAD and in 49 men with normal angiography as well as in 51 women with CAD and in 51 normal women was investigated. Both spinal and femoral BMD values for men were higher than those of women (P<0.05). Neither femoral nor spinal BMD values were different in patients with or without CAD. In addition, BMD values were not associated with the severity of CAD. Body massindex (BMI) was positively correlated with BMD both in men and women, whereas age and anti-diabetic treatment were linked with lower BMD in women. In conclusion, in this study CAD was not related to low BMD. However, BMI was an independent predictor of diminished BMD

Development of multiplex real-time quantitative PCR for simultaneous detection of Chlamydia trachomatis, Mycoplasma hominis, Ureaplasma urealyticum, and Mycoplasma genitalium in infertile women

Purpose: Sexually Transmitted Diseases (STDs) can cause sterility and many other problems for women planning pregnancy. Currently, almost 340 million people worldwide suffer from Sexually Transmitted Infections (STIs). This study made attempts to quickly identify STDs' most critical infectious agents using dedicated primers and probes. Methods: The present study was done on the cervical samples of 200 infertile women. After extracting the total DNA of Chlamydia trachomatis, Mycoplasma hominis, Ureaplasma urealyticum, and Mycoplasma genitalium, quantitative methods were employed to determine the rate of target bacteria using multiplex real-time PCR. Results: The multiplex qPCR showed the rates of 47%, 16%, 46%, and 16.5% for Chlamydia trachomatis, Mycoplasma hominis, Ureaplasma urealyticum, and Mycoplasma genitalium in infertile women, respectively. In some patients, there were co-infections with two or three bacteria. The diagnostic approach used in our research could be employed as an alternative detection tool to identify the four most common STD-associated bacterial agents while detecting mixed infections. Conclusions: Infertile women with no biological problems could have their genital tract checked using this newly designed identification technique and get proper treatment for their infections as quickly as possible
