Effect of Laser Fluence on the Characteristics of Ag Nanoparticles Produced by Laser Ablation

引用

Soft Nanoscience Letters 2013年第4期3卷 93-100页

作者： davoud Dorranian Shiva Tajmir Farzane Khazanehfar Laser Lab. Plasma Physics Research Center Science and Research Branch Islamic Azad University Tehran Iran.

6-12 nm silver nanoparticles were synthesized by the pulsed laser ablation of a high purity silver bulk in distilled water. Effect of laser fluence on the size, morphology and structure of produced nanoparticles has been studied experimentally. Pulses of a Q-switched Nd:YAG laser of 1064 wavelength at 7 ns pulse width at different fluences were employed to irradiate the silver target in water. The UV-Visible absorption spectra of the Ag nanoparticles exhibit surface plasmon resonance absorption peak in the UV region. TEM and SEM micrographs, in a good agreement with DLS results, indicate that with increasing the laser fluence the average size of spherical Ag nanoparticles is decreased. It is found that Ag nanoparticles exhibit photoluminescence emission with two peaks because of the inter band transition and electron-hole recombination.

引用

Chinese Journal of Traumatology 2019年第4期22卷 228-232页

作者： Tania Azadi davoud Khorasani-Zavareh Farahnaz Sadoughi School of Health Management and Information Sciences Iran University of Medical Sciences Tehran Iran Safety Promotion and Injury Prevention Research Center Health in Disaster and Emergency Department School of Health Safety and Environment Shahid Beheshti University of Medical Sciences Tehran Iran Health Management and Economics Research Center School of Health Management and Information Sciences Iran University of Medical Sciences Tehran Iran

Purpose: Child injuries are a global public health problem and injury surveillance systems (ISS) can be beneficial by providing timely data. However, ISS implementation has challenges. Opinions of stakeholders of ISS implementation barriers and facilitators are a good source to understand this phenomenon. The aim of this study is to investigate barriers and facilitators of implementing ISS in Iran. Methods: This is a qualitative study. Data were gathered through interviews with 14 experts in the field of child injury and prevention from Iranian Ministry of Health and Medical Education (MOHME), medical univers让ies, pediatrics hospitals, general hospitals and health houses during January 2017 to September 2017. Data collection and analysis con tinued until data saturation. Data were analyzed using con tent analysis through identifying meaning units. Results: Barriers were classified in three main categories and nine subcategories including management barriers (including performance, coordination and cooperation, supervision and attitude), weakness in data capture and usage (including data collection, data recording and data dissemination) and resource limitation (including human and financial resources). Facilitators identified in three areas of policy making (including empowerment and attitude), management (including organization, function and cooperation and coordination) and data recording and usage (including data collection/distTibution and data recording). Conclusion: The most important barrier is lack of national policy in child injury prevention. The most important facil让ator is improving MOHME function through passing supportive regulations. Effective data usage and dissemination of information to those requiring data for policy making can help reduce child injuries. Coalition of stakeholders helps overcome existing barriers.

The deposits of Permian system in Kuh-e-Gahkum consist of 480 m clastic subdiffusion of Faraghan Formation and carbonates of Dalan Formation. In this section, the sediments of Faraghan Formation, which is gradationally overlain by Dalan formation, unconformably overlies Zakin Formation (Lower Carboniferous). In the upper part, Kangan Formation rests on the Permian deposits with an erosional and unconformable contact. Studying the microscopic thin sections led to the identification of 37 genera and 37 species of Foraminifera as well as 14 genera and 15 species of algae. According to the identified foraminifera in Faraghan and Dalan Formations, the age of the rock units in Permian system is assigned to Julfian-Asselian.

引用

Open Journal of Preventive Medicine 2015年第2期5卷 72-77页

作者： Mina-Sadat Hashemiparast davoud Shojaeizadeh Kamal Aezam Azar Tol Department of Health Promotion and Education School of Public Health Tehran University of Medical Sciences Tehran Iran Department of Epidemiology and Biostatistics School of Public Health Tehran University of Medical Sciences Tehran Iran

Urinary Tract Infection (UTI) is one of the most common bacterial infections among children using preventive manipulations, especially among children less than 6 years old. This study aimed at exploring factors which could affect urinary tract infection prevention among children. A descriptive analytical study was conducted on 70 mothers who had children less than 6 years old in 2013. Multistage cluster sampling method was utilized in which each kindergarten was considered as a cluster and data were collected by a researcher-made questionnaire designed based on Health Belief Model (HBM). Validity and reliability of questionnaire were confirmed by a pilot study. ANOVA and Pearson Correlation Coefficient were conducted using SPSS, version 18. The mean and standard deviation of knowledge and practice were 6.96 ± 2.14 and 15.47 ± 1.54 respectively. Means and standard deviation of Health Belief Model constructs (perceived susceptibility, perceived severity, perceived benefits, perceived barriers and self-efficacy) were 17.64 ± 2.50, 22.02 ± 2.55, 20.90 ± 2.38, 27.56 ± 5.20 and 21.49 ± 3.18 respectively. More participants were in the moderate levels of knowledge (74.3%) and practice (45.7%). These findings revealed a significant relation between practice and perceived susceptibility (p = 0.02), perceived barriers (p = 0.001), self-efficacy (p = 0.014) and cues to action (p = 0.016). Based on the current study, the intervention based on Health Belief Model can be useful to improve preventive behaviors of Urinary Tract Infection.

Association between Weight Change during Treatment and Treatment Outcome in Patients with Smear Positive Pulmonary Tuberculosis

引用

Open Journal of Preventive Medicine 2014年第6期4卷 446-453页

作者： Mohammad Khajedaluee Maliheh Dadgarmoghaddam davoud Attaran Amirhossein Zabihi Seyedhassan Ashrafi School of Medicine Mashhad University of Medical Science Mashhad Iran

Tuberculosis (TB) is known as a disease of poverty and declared as a global public health emergency by World Health Organization (WHO). Pulmonary tuberculosis is the most common type of TB and is a wasting disease. It is expected that the patients who lost weight during the course of disease, will gain weight during successful treatment. So the aim of this study was to assess the body weight changes through the treatment and its possible association with treatment outcome in TB patients in Nishapur, an ancient city in Razavi Khorasan province in Iran. This is an observational analytical study. Patients were selected according to inclusion and exclusion criteria and available information. Treatment Protocol for all patients was Directly Observed Treatment, short Course Strategy (at least 6 months). All patients were weighed at the beginning of treatment, after two months and at the end of treatment. Outcome of treatment was classified into: cured, completed treatment, treatment failure and death. Then the impact of weight changes during treatment was compared in subgroups. From 874 patients, 819 patients (93.9%) were new cases, 48 (5.3%) relapse, 5 patients (0.6%) patients who did not complete their treatment and 2 (0.2%) had failed prior therapy. The most common symptoms in all patients were: cough, sputum, weight loss, fever, sweats, and hemoptysis. 8.1% of patients had radiologic signs and the most common signs were cavity (2.9%). The weight change during treatment was 2.91 ± 5.59 kg in cured group, 3.3 ± 3.29 kg in completed treatment group, 2.95 ± 5.59 kg in treatment failure group and 1.02 ± 3.27 in dead group respectively. These differences were statistically significant between the four groups (p < 0.03). We can conclude that body weight change can be used as a predictor for the treatment outcome.

Reservoir Characterization and Geostatistical Modeling of Ilam &Sarvak Formations in One of Oil Fields in Southwest of Iran

引用

Open Journal of Geology 2017年第6期7卷 789-795页

Exploration and exploitation of hydrocarbon reservoirs have been always time consuming with high risk and high cost. In this regard, assessment of reservoir characterizations and information about spatial distribution of its parameters play an important role in adaptation of suitable strategies for hydrocarbon resources management. There are only few numbers of oil wells cored in every oil field due to high cost, time-consuming process, and other drilling problems. Therefore, it is required to use alternative estimation methods in order to achieve the petro-physical parameter in total space of reservoir. In this research, geostatistical methods have been applied as a new approach to calculate and estimate porosity and permeability of reservoir in one of southwestern oil fields of Iran. The information obtained from 86 wells in one of southwestern oil fields of Iran has been available in this study. Physical parameters of porosity and permeability are vital parameters that should be estimated in studied reservoir. This study indicated that Gaussian Variogram Model is the best model to predict porosity and permeability values in field. Error means of actual values of porosity are equal to 6.9% and for permeability are 11.21% using Gaussian Model. Also, after prediction of porosity and permeability values for field, distribution of these parameters in field was illustrated in two-dimensional and three-dimensional modes besides distribution and location of wells in field in order to determine the best drilling spots and reduce risk of drilling operations.

The Heat Treatment Effect on the Oxidation Rate of the Ge-Doped Si(100)

引用

Open Journal of Applied Sciences 2013年第1期3卷 107-111页

作者： Bashir Nedaee Shakarab Ali Baghizadeh davoud Agha-Ali Gol Department of Physics Ardabil Branch Islamic Azad University Ardabil Iran Van de Graaff Laboratory Physics Department Nuclear Science and Technology Research Institute Tehran Iran

In this paper, the Si(100) substrate was implanted by Ge ions at different doses to study the effect of the preliminary heat treatment on the wet oxidized layer of the Si using Rutherford Backscattering Spectroscopy and Atomic Force Microscopy. We found that the change of the silicon oxide thickness and its morphology under the influence of the Ge dopant is mostly dependent on the damaged surface layer of the Si substrate after ion implantation. By choosing different doses of the implantation and subsequent annealing process, we tried to get different level of the induced damage, enabled us to investigate the role of the pre-heating and subsequent recrystalization of the damaged substrate on the silicon oxidation process under the effect of the implanted Ge ions. By the determination of the effect of these parameters, we can better identify the optimal conditions of getting the oxide layer with proper thickness and morphology.
