Bashiri, Azadeh,Ghazisaeedi, Marjan,Shahmoradi, Leila The Korean Pediatric Society 2017 Clinical and Experimental Pediatrics (CEP) Vol.60 No.11

Attention deficit hyperactivity disorder (ADHD) is one of the most common psychiatric disorders in childhood. This disorder, in addition to its main symptoms, creates significant difficulties in education, social performance, and personal relationships. Given the importance of rehabilitation for these patients to combat the above issues, the use of virtual reality (VR) technology is helpful. The aim of this study was to highlight the opportunities for VR in the rehabilitation of children with ADHD. This narrative review was conducted by searching for articles in scientific databases and e-Journals, using keywords including VR, children, and ADHD. Various studies have shown that VR capabilities in the rehabilitation of children with ADHD include providing flexibility in accordance with the patients' requirements; removing distractions and creating an effective and safe environment away from real-life dangers; saving time and money; increasing patients' incentives based on their interests; providing suitable tools to perform different behavioral tests and increase ecological validity; facilitating better understanding of individuals' cognitive deficits and improving them; helping therapists with accurate diagnosis, assessment, and rehabilitation; and improving working memory, executive function, and cognitive processes such as attention in these children. Rehabilitation of children with ADHD is based on behavior and physical patterns and is thus suitable for VR interventions. This technology, by simulating and providing a virtual environment for diagnosis, training, monitoring, assessment and treatment, is effective in providing optimal rehabilitation of children with ADHD.

Azadeh Bashiri,Behrouz Alizadeh Savareh,Marjan Ghazisaeedi 대한응급의학회 2019 Clinical and Experimental Emergency Medicine Vol.6 No.4

Clinical decision support systems are interactive computer systems for situational decision making and can improve decision efficiency and safety of care. We investigated the role of these systems in enhancing prehospital care. This narrative review included full-text articles published since 2000 that were available in databases/e-journals including Web of Science, PubMed, Science Direct, and Google Scholar. Search keywords included “clinical decision support system,” “decision support system,” “decision support tools,” “prehospital care,” and “emergency medical services.” Non-journal articles were excluded. We revealed 14 relevant studies that used such a support system in prehospital emergency medical service. Owing to the dynamic nature of emergency situations, decision timing is critical. Four key factors demonstrated the ability of clinical decision support systems to improve decision-making, reduce errors, and improve the safety of prehospital emergency activity: computer-based, offer support as a natural part of the workflow, provide decision support in the time and place of decision making, and offer practical advice. The use of clinical decision support systems in prehospital care resulted in accurate diagnoses, improved patient triage and patient outcomes, and reduction of prehospital time. By improving emergency management and rescue operations, the quality of prehospital care will be enhanced.

Hadis Bashiri,Samira Nesari,Malihe Sarabadan 한국화학공학회 2020 Korean Journal of Chemical Engineering Vol.37 No.2

Microwave radiation was used for synthesis of an adsorbent using rice husk. The activation of the rice husk sample was performed by H3PO4 and 6min of the microwave radiation with power 700W. The synthesized adsorbent was characterized by SEM, FT-IR, BET and XRD techniques. These analyses showed the prepared adsorbent is an amorphous and mesoporous nano-adsorbent with BET surface area 276.43m2/g. It has some aromatic groups and O-H, C=C, C–O and C=O bands in its structure. Adsorption of alizarin yellow on the synthesized nano-adsorbent was investigated and the influences of adsorbent dosage (0.1-2 g/L) and temperature (25-40 oC) on dye removal from aqueous solution were investigated. The kinetic, equilibrium and thermodynamics studies of alizarin yellow removal from aqueous solution using the prepared adsorbent were carried out. The adsorption performance of alizarin yellow on the prepared adsorbent was compared with a commercial activated carbon. The importance of this study is in providing a condition for preparation of a low cost adsorbent with high adsorption capacity (712.63 mg/g) for alizarin yellow. The comparison of adsorption capacities of the prepared adsorbent from rice husk and other adsorbents proved it is a perfect adsorbent.

Ali Bashiri Rezaie,Majid Montazer 한국섬유공학회 2019 Fibers and polymers Vol.20 No.5

In this research for the first time, surface functionalization of polyester fibers was performed via one-step, facileand clean strategy through green synthesis and deposition of iron oxide nanoparticles for photocatalytic and magneticapplications. The commercial ash of Seidlitzia Rosmarinus plant was used as a natural alkaline source for nanoparticlessynthesis as well as surface modification of polyester substrate and iron sulfate as metal precursor. The presence of iron oxidenanoparticles on polyester fibers was proved by X-ray diffraction analysis, energy-dispersive X-ray spectroscopy, mapping,field-emission scanning electron microscope images and Fourier transform infrared spectra. The fabricated samples exhibitedvery good photocatalytic activities toward methylene blue decoloration about 95.45 % after 48 h exposing to sunlightirradiation. In addition, they indicated appropriate magnetic properties with saturated magnetization of 2.30 and 1.69 emu/gat room temperature. The coloring effect, weight change and wettability behavior of the fabricated samples were alsoinvestigated. The mentioned route in this paper can simply be scaled up as an eco-friendly and scalable route for surfacefunctionalization of polymeric substrates via synthesis and deposition of iron oxide nanoparticles to acquire durable photoand magneto activities on polymers for different applications.

Maliheh Sarabadan,Hadis Bashiri,Seyed Mahdi Mousavi 한국화학공학회 2019 Korean Journal of Chemical Engineering Vol.36 No.10

Natural zeolite as a low cost clay was tested for removal of crystal violet known as a noxious dye. Five characterization techniques were used for this study. Optimizing and modeling of adsorption were performed at minimum time by an applicable technique named as response surface methodology (RSM). Three effective variables (pH, temperature (T) and adsorbate-to-adsorbent ratio (a/A)) were monitored to obtain the dye removal efficiencies. The maximum removal of dye was obtained at pH=10, T=25 oC and a/A=0.1 g/g. For natural zeolite, the Fractal-Langmuir model was selected as an appropriate model for kinetic studies and the Freundlich isotherm was the best isotherm for equilibrium studies. Thermodynamic investigations showed that the adsorption of dye on natural zeolite is endothermic process and a spontaneous reaction. The maximum dye adsorption capacity of natural zeolite and Merck activated carbon on the surface of each adsorbent was obtained at 177.75 and 84.11mg/g, respectively. In comparison with the maximum adsorption capacity of activated carbon obtained from Merck Company, we can conclude that natural zeolite possesses a higher adsorption capacity. These results reveal that, natural zeolite is an excellent and affordable adsorbent for removal of crystal violet from wastewater as compared to activated carbon.

Comparison of different fluid dynamics in activated sludge system for the treatment of a stimulated milk processing wastewater: Process analysis and optimization

Ali Akbar Zinatizadeh Lorestani,Hojjatollah Bashiri,Azar Asadi,Hossein Bonakdari 한국화학공학회 2012 Korean Journal of Chemical Engineering Vol.29 No.10

Wastewater from the milk industry usually undergoes activated sludge ahead of refining treatments, final discharge or reuse. To identify the most effective bioreactor hydraulic regime for the secondary treatment of wastewater resulting from the milk industry in an activated sludge system, two lab-scale activated sludge systems characterized by a different configuration and fluid dynamics (i.e., a compartmentalized activated sludge (CAS) with plug flow regime and a complete mixed activated sludge (AS)) were operated in parallel, inoculated with the same microbial consortium and fed with identical streams of a stimulated dairy wastewater. The effect of three process and operational variables--influent chemical oxygen demand (COD) concentration, sludge recycle ratio (R) and hydraulic retention time (HRT)--on the performance of the two systems were investigated. Experiments were conducted based on a central composite face-centered design (CCFD) and analyzed using response surface methodology (RSM). The region of exploration for treatment of the synthetic wastewater was taken as the area enclosed by the CODin (200, 1,000 mg/l), R (1, 5), and HRT (2, 5 h) boundaries. To evaluate the process, three parameters, COD removal efficiency (E), specific substrate utilization rate (U), and sludge volume index (SVI), were measured and calculated over the course of the experiments as the process responses. The change of the flow regime from complete-mix to plug flow resulted in considerable improvements in the COD removal efficiency of milk wastewater and sludge settling properties. SVI levels for CAS system (30-58 ml/g) were considerably smaller that for the AS system (50-145 ml/g). In addition, the biomass production yield could be reduced by about 10% compared to the AS system. The results indicated that for the wastewater, the design HRT of a CAS reactor could be shortened to 2-4 h.

Maryam Razmkhah,Majid Montazer,Ali Bashiri Rezaie,Mahnaz Mahmoudi Rad 한국공업화학회 2021 Journal of Industrial and Engineering Chemistry Vol.101 No.-

The lowering intake of organic dyes and their auxiliaries by employing nanoparticles for some specialtextile coloration is novel and interesting topic. Nonetheless, application of reducing, stabilizing andother chemical agents in textile nano-coloration is still undesirable from both environmental andhuman/aquatic life viewpoints. This research renders a facile technique for wool coloration throughlocally forming selenium nanoparticles using sodium selenite without using other chemicals. Beingindustrially enforceable, free from use of additional chemicals, showing photo-active ability to discolorthe dyeing effluent and low-toxic colorant are the main privileges of the used method. The wool fabricswere colored light to dark orange depending on coloration time and concentration of sodium selenite. Also, the color fastness properties against washing, rubbing and acid/alkaline spotting of prepared sampleswere excellent. Moreover, the colored fabrics indicated reasonable bactericidal and fungicidal performancestoward Escherichia coli, Staphylococcus aureus and Candida albicans (95, 70 and 100 %,respectively) and still remained compatible with human skin. The in-situ synthesis of selenium nanoparticleson wool fabric not only colored the wool but also promoted the UV-protecting performance by61.82 %, photocatalytic activity through methylene blue discoloration under sunlight by 97.22 % and tensilestrength by 11.27 %.
