Informed consent should not be regarded as a rigid process. Instead, it should be regarded as a flexible process that provides patient with the right amount of information required to facilitate meaningful decision-making. Informed consent is an important ethical and practical part of patient care. Understanding the moral foundation of informed consent can help to guide therapists in their communication with all patients. Nurses, as members of the multidisciplinary team, are currently key contributors in providing information to patients regarding the treatment process. But in this process, there are some challenges that make it difficult. This paper describes the underlying ethical and regulatory requirements as well as related challenges regarding informed consent in the context of a nursing practice in Iran.

Investigation of live and dead status of airborne bacteria using UVAPS with LIVE/DEAD® BacLight Kit

Nasrabadi, Ali Mohamadi,An, Sanggwon,Kwon, Soon-Bark,Hwang, Jungho Elsevier 2018 Journal of aerosol science Vol.115 No.-

<P><B>Abstract</B></P> <P>Although the amount of allergens and toxins being originated from viable bacteria is higher than that from dead bacteria, monitoring concentrations of dead bacteria as well as live bacteria is an important issue related to human health. The ultraviolet aerodynamic particle sizer (UVAPS) is an instrument to measure the size distribution of only viable bioaerosols. Therefore, the main objective of this study is to detect percentages of dead as well as live airborne bacteria by using a LIVE/DEAD BacLight Bacterial Viability Kit (L7012, Molecular probes, USA) together with UVAPS. Two different bacteria species, <I>Escherichia coli</I> (<I>E.coli</I>) and <I>Micrococcus luteus</I> (<I>M. luteus</I>), were used for tests. Percentages of fluorescence emitted from these bacteria were compared with those from standard PSL and dust particles. The increased percentages for dead <I>E. coli</I> and dead <I>M. luteus</I> were 41% and 75%, respectively, while this kit did not show any effective influence on fluorescence percentages of polystyrene latex and dust particles. Field test was carried out in various indoor environments to investigate percentages of live and dead airborne bacteria.</P> <P><B>Highlights</B></P> <P> <UL> <LI> The LIVE/DEAD® BacLight Kit makes the UVAPS to be capable to monitor dead bacteria as well as live bioaerosols. </LI> <LI> The ratio of live to dead bacteria did not much affect the fluorescence percentage after staining. </LI> <LI> Field test was carried out and a correlation was obtained between two fluorescence percentages before and after staining. </LI> </UL> </P>

Numerical investigation for the effect of electro-aerodynamic nanoparticle deposition on the performance of a metal grid type transparent electrode

Nasrabadi, Ali Mohamadi,Hwang, Jungho Pergamon Press 2018 Journal of aerosol science Vol.116 No.-

<P>Electro-aerodynamic particle jet printing is a method to fabricate transparent electrodes, which have been used in applications such as solar cells, display screens, and touchscreen panels. The desired TE sheet resistance and transmittance are realized by trial and error through repeated printing experiments with different parameters such as nozzle size, nozzle-to-substrate distance, airflow rate, electric field strength, and printing time. Because this trial-and-error approach requires a great deal of time, cost, and effort, we present a numerical approach using computational fluid dynamics to simulate nanoparticle deposition using dynamic mesh. The particle trajectories are studied by considering both momentum and electrical forces simultaneously. After validation of numerical deposition height results with experimental data, we investigate the effects of pitch distance and printing time on sheet resistance and transmittance for a given grid line width. Increasing grid thickness with increasing printing time decreases sheet resistance while transmittance remains constant. Our calculation shows that the sheet resistance for pitch distance of 2000 mu m decreased by a factor of approximately 62 after 10 min of printing while the transmittance remained constant.</P>

Real-time separation of aerosolized <i>Staphylococcus epidermidis</i> and polystyrene latex particles with similar size distributions

Mohamadi Nasrabadi, Ali,Han, Jang Seop,Massoudi Farid, Milad,Lee, Sang-Gu,Hwang, Jungho Informa UK (TaylorFrancis) 2017 AEROSOL SCIENCE AND TECHNOLOGY Vol.51 No.12

<P>For rapid and effective detection of airborne microorganisms, it is preferable to remove dust particles during the air sampling process because they can reduce the detection accuracy of measurements. In this study, a methodology of real-time separation ofaerosolized Staphylococcus epidermidis (S. epidermidis) andpolystyrene latex (PSL) particles of similar size was investigated. These two species represent biological and non-biological particles, respectively. Due to their different relative permittivities, they grasp different numbers of air ions under corona discharge. After these charged particles enter a mobility analyzer with airflow, in which an electric field is applied perpendicular to the airflow, the S. epidermidis and PSL particles separate, due to the difference in their electric mobilities, and exit through two different outlets. Purities and recoveries for S. epidermidis and PSLat their respective outlets were determined with measurements of aerosol number concentrations and ATP bioluminescence intensities at the inlet and two outlets. The results were that purities for PSL and S. epidermidis were 70% and 80%, respectively. This methodology provides a rapid and simple way to increase the detection accuracy of bacterial agents in air.</P>

Uniform Micellization: The Key to Enhanced Mechanical Strength and Swelling Efficiency of Chitosan Hydrogel

Bijan Nasri-Nasrabadi,Akif Kaynak,Cynthia Wong,Pejman Heidarian,Khashayar Badii,Abbas Z. Kouzani 한국섬유공학회 2019 Fibers and polymers Vol.20 No.1

The fabrication of hydrophilic porous hydrogel, with high mechanical strength and good uptake capacity is desirable for a broad range of applications such as drug delivery and liquid sensors. The usual methods are limited to the production of structures with high density of covalently crosslinked networks that restricts the polymer chain rearrangement, resulting in non-uniformed pore size distribution. Covalent networks also limit the activity of functional groups and influence the uptake properties of the polymer. In this study, we proposed simple cyclic cryogelation for the fabrication of hydrogels with uniform pore sizes via controlling the micellization and crystal formation. The chitosan based hydrogels ionically crosslinked with 8 % (w/v) of tripoli phosphate sodium (TPP) displayed high Young’s modulus (63 MPa) after cyclic freezethawing. The liquid uptake capacity of the samples treated with 8 % (w/v) TPP solution at pH 4 showed a slight decrease of about 29 % in comparison to that of non-cyclic processed samples (36 %).

Language,Education ; Persian EFL Learners` Cross-Cultural Understanding and Their L2 Proficiency

( Azadeh Nasri Nasrabady ),( Abbass Islami Rasekh ),( Reza Biria ) 경희대학교 글로벌인문학술원 2011 비교문화연구 Vol.24 No.-

The totality of language learning comprises three integrated components: linguistic, cultural, and attitudinal (Wilkes, 1983).Positively sensitizing students to cultural phenomena is urgent and crucial. A positive attitude toward L2 culture is a factor in language learning that leads to cross cultural understanding. This research examined, through a survey analysis, how three groups of students (one high school group and two university student groups) viewed the role of their foreign culture (i.e., American and British cultures) in achieving cultural understanding. The focus was upon how EFL learners approach the target language culture as well as their own culture.
