New isotherm regularity and an equation of state for gases and liquids

Mehdi Baniasadi,Maryam Baniasadi,Sattar Ghader 한국공업화학회 2012 Journal of Industrial and Engineering Chemistry Vol.18 No.1

In this paper an isotherm regularity has been introduced for gases and liquids based on intermolecular potential energy. The experimental data has been used to demonstrate the validity of the regularity. A non-linearity relationship exists between (Z 1)v3 and r for all isotherms of liquids and gases. The basis for this regularity is intermolecular potential which is a modified Lennard–Jones potential (9, 6, 3) for repulsive, dispersion, dipole–dipole and longer-ranged interactions. The isotherm regularity is equivalent to a virial-like EOS for which the parameters of the isotherm form the corresponding second, third and fourth virial-like coefficients. The equation of state is simple and ready to use. The parameters of equation of state are determined by fitting isothermal regularity to experimental data. The new equation of state provides excellent results in homogenous gas and homogeneous liquids region to very high pressures while its predictions in gas-liquid transition have more deviations. Densities of 1828data points of 21 components have been calculated over the entire range of data with a maximum pressure of 1000 MPa. The average absolute deviation between calculated and experimental densities for gases, liquids and gas-liquid transition region are 0.06%, 0.03% and 0.90%, respectively.

Rates based on age-adjusted incidence of colorectal cancers over a 10-year period in Kerman, the biggest province of Iran, were estimated from 2003 to 2013. Data were obtained from the population-based cancer registry unit of Kerman University of Medical Sciences (CR-KMU). Information included age, sex, city, ICD-O and year of registry. Our trend analyses cover 3.91% of the Iranian population. The data set comprised cases diagnosed from 2003 to 2013.The population of over 20 years was interpolated using 2003 and 2010 censuses. Then, truncated age-adjusted incidence rates were calculated. Increase was noted from 2003-2009 to 2010-2013 for 731 cancer cases considered in the analysis. The increases was most prominent in 2009. Totally, the frequency of the cancer was greater in males. Moreover, calculating truncated age-adjusted incidence rate indicated that the most prevalent age of colorectal incidence was in the 50-59 year age group except in 2007-2008 and 2012- 2013, when greatest incidences occurred in people aged 60-69 years. Our data revealed that the incidence rates of colorectal cancer have increased over the past decade in our region of Iran.

Shadi Baniasadi,Arthit Chairoungdua,Yuji Iribe,Yoshikatsu Kanai,Hitoshi Endou,Ken-ichi Aisaki,Katsuhide Igarashi,Jun Kanno 대한약학회 2007 Archives of Pharmacal Research Vol.30 No.4

Inhibition of LAT1 (L-type amino acid transporter 1) activity in tumor cells could be effective in the inhibition of tumor cell growth by depriving tumor cells of essential amino acids. Because of the high level of expression of LAT1 in tumor cells, LAT1 inhibitors would be useful for anticancer therapy in suppressing tumor growth without affecting normal tissues. In recent years, cDNA microarray technique is useful technology for anticancer drug development. It allows identifying and characterizing new targets for developments in cancer drug therapy through the understanding genes involved in drug action. The present study was designed to investigate gene expression profile induced by LAT1 inhibitor using gene chip technology. Human bladder carcinoma cells (T24 cells) were treated with classical system L inhibitor 2-aminobicyclo-(2, 2, 1)-heptane-2-carboxylic acid (BCH). Gene chip experiment was applied for treated and untreated cells after 3 and 12 h. Two independent experiments with a high degree of concordance identified the altered expression of 151 and 200 genes after 3 and 12 h BCH treatment. Among these genes, 132 and 13 were up-regulated and 19 and 187 were down-regulated by 3 and 12 h BCH treatment respectively. We found that BCH affected the expression of a large number of genes that are related to the control of cell survival and physiologic behaviors. These data are useful for understanding of intracellular signaling of cell growth inhibition induced by LAT1 inhibitors as candidate for anticancer drug therapy.

Modifying GMA equation of state for description of (P, ρ, T) relation of gas and liquids over an extended pressure range

Mehdi Baniasadi,Sattar Ghader,Hassan Hashemipour 한국화학공학회 2011 Korean Journal of Chemical Engineering Vol.28 No.3

The main concern of this paper is on the improvement of the GMA equation of state (Fluid Phase Equilibr. 230 (2005) 170) which has been used for density calculation of components in liquid region with excellent accuracy. However, the GMA equation of state cannot predict the density of components in either the gas or gas-liquid transition region. The GMA equation of state is based on intermolecular potential energy; therefore, the potential energy of the GMA equation of state is corrected and an equation of state is obtained. The final form of the new equation of state is a regularity between (Z−1)^(v3) and ρ for all temperatures, which is based on modified Lennard-Jones potential (9, 6,3). The capability of the new equation of state is examined by comparing the results with experimental data in homogeneous gas, homogeneous liquid and gas-liquid transition region from low to very high pressures. The new equation of state gives excellent results in homogeneous gas and homogeneous liquid region, while the predictions in the gas-liquid transition have more deviations. The average absolute deviation between calculated and experimental densities for 1979data points of 24 components is 0.25% over the entire range of data with a maximum pressure of 1,000 MPa.

Hamid Baniasadi,Fariborz Rashidi 한국화학공학회 2019 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.57 No.6

Two-phase flow near the wellbore in volatile oil reservoirs causes complications in well test analysis. In this study, the flow behavior of volatile oil reservoirs below the bubble-point pressure and the potential of radial composite model for interpretation of two-phase well test in volatile oil reservoirs was investigated. A radial composite model was used for two-phase well test analysis. A new procedure was developed to interpret well test data and estimate the radius of the two-phase region. The changes in fluid composition near the wellbore during drawdown test were found to increase the saturation pressure, which affects the saturation profile during build-up. Well test results showed that the radial composite method is a powerful tool for well test characterization and estimation of reservoir parameters. The proposed procedure was able to estimate the reservoir parameters and radius of the two-phase region with acceptable accuracy.

S. Mahmood Fatemi,Aminreza Baniasadi,Mahrokh Moradi 한국물리학회 2017 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.71 No.1

If an ideal membrane for gas separation is to be obtained, the following three characteristics should be considered: the membrane should be as thin as possible, be mechanically robust, and have welldefined pore sizes. These features will maximize its solvent flux, preserve it from fracture, and guarantee its selectivity. Graphene is made up of a hexagonal honeycomb lattice of carbon atoms with sp2 hybridization state forming a one-atom-thick sheet of graphite. Following conversion of the honeycomb lattices into nanopores with a specific geometry and size, a nanoporous graphene membrane that offers high efficiency as a separation membrane because of the ultrafast molecular permeation rate as a result of its one-atom thickness is obtained. Applications of nanoporous graphene membranes for gas separation have been receiving remarkably increasing attention because nanoporous graphene membranes show promising results in this area. This review focuses on the recent advances in nanoporous graphene membranes for applications in gas separation, with a major emphasis on theoretical works. The attractive properties of nanoporous graphene membranes introduce make them appropriate candidates for gas separation and gas molecular-sieving processes in nanoscale dimensions.

This article presents a systematic review of the literature on barriers associated with mHealthreported by healthcare professionals. Methods: This systematic review was carried out to identify studies published fromJanuary 2015 to December 2019 by searching four electronic databases (PubMed/MEDLINE, Web of Science, Embase, andGoogle Scholar). Studies were included if they reported perceived barriers to the adoption of mHealth from healthcare providers’perspectives. Content analysis and categorization of barriers were performed based on a focus group discussion thatexplored researchers’ knowledge and experiences. Results: Among the 273 papers retrieved through the search strategy, 18works were selected and 18 barriers were identified. The relevant barriers were categorized into three main groups: technical,individual, and healthcare system. Security and privacy concerns from the category of technical barriers, knowledge andlimited literacy from the category of individual barriers, and economic and financial factors from the category of healthcaresystem barriers were chosen as three of the most important challenges related to the adoption of mHealth described in the includedpublications. Conclusions: mHealth adoption is a complex and multi-dimensional process that is widely implementedto increase access to healthcare services. However, it is influenced by various factors and barriers. Understanding the barriersto adoption of mHealth applications among providers, and engaging them in the adoption process will be important for thesuccessful deployment of these applications.

Yuchun Li,Meilin Li,Xiangtong Kong,Arefeh Baniasadi,Ahmed Hasan Shaker,H. Elhosiny Ali Techno-Press 2023 Advances in nano research Vol.15 No.3

This research aims to explore factors influencing creativity among the employees of nanotechnology companies. Further, this survey aimed to investigate the role of psychological capital (PS), job satisfaction (JS) and corporate social responsibility (CSR) as sources to foster creativity. Participants included 375 employees of nanotechnology companies in China. Sequential mediation analysis revealed that creativity was significantly influenced by psychological capital, job satisfaction and corporate social responsibility. Furthermore, not only psychological capital, job satisfaction and corporate social responsibility were directly and indirectly related to creativity but also explained 67.35% variance of it. It seems that having more psychological resources, more well-being and good feelings concerning performance in the workspace and the efforts of companies to improve employee welfare are among the most important factors in increasing employee creativity. Our findings can help companies, especially nontechnology companies, in focusing on factors fostering the creativity of employees, because creativity enhances and promotes the performance and success of companies.

( Somayehsadat Eslami ),( Firoozeh Mirzaee ),( Moghaddameh Mirzaee ),( Mahboubeh Valiani ),( Hassan Baniasadi ) 대한폐경학회 2021 대한폐경학회지 Vol.27 No.3

Objectives: Menopause is associated with a plethora of problems particularly hot flashes. This study aims to compare the effect of biofeedback and auriculotherapy on hot flashes in menopausal women in Kerman, Iran. Methods: This study, a pilot clinical trial with a pretest-posttest control group design, was conducted on 39 postmenopausal women referring to the private offices of obstetricians and gynecologists in Kerman, Iran, in 2019. The participants were divided into 3 groups (n = 13 in each group) using simple random assignment. In the first and second intervention groups, the biofeedback program and auriculotherapy were conducted by the researcher 10 times in 45- and 30-min sessions twice a week, respectively. In the control group, routine care was provided. The participants completed the checklist of severity and frequency of hot flashes before, immediately, and 4 weeks postintervention. Results: Immediate and 4-week postintervention biofeedback and auriculotherapy had a significant effect on reducing the severity and frequency of hot flashes (P < 0.001). However, the effect of auriculotherapy on mitigating the severity and frequency of hot flashes immediately and 4-week postintervention was more significant than that of biofeedback (P < 0.001). Conclusions: Biofeedback and auriculotherapy may be effective in the treatment of hot flashes. Hence, they can be recommended as therapeutic methods for postmenopausal women.
