Three dimensional finite element study on torsion extrusion processing of 1050 aluminum alloy

引用

Transactions of Nonferrous Metals Society of China 2012年第11期22卷 2771-2776页

作者： Ali KHOSRAVIFARD Mohammad JAHEDI amir hossein YAGHTIN Department of Materials Engineering Shiraz Branch Islamic Azad University Department of Materials Science and Engineering School of Engineering Shiraz University

The capability of the torsion extrusion （TE） process as a severe plastic deformation （SPD） method was compared with the conventional forward extrusion （FE） process. The TE and FE processes were successfully performed on AA1050 alloy samples at room temperature. To simulate the above mentioned processes, finite element analysis was carried out using the commercial elasto-plastic finite element analysis ABAQUS/Explicit Simulation. It is shown that load requirement for the TE process is lower than that for the FE process. The equivalent plastic strain calculated by the FEA proved that higher values of strain are imposed to the sample in the TE process. The strain distribution for the TE sample at the final stage of extrusion shows smoother strain gradient in comparison with the one produced by the FE process.

Background: The use of traditional and complementary medicine (T&CM) is increasing in both developed and developing countries. The school of Persian medicine (PM) in Iran is a comprehensive medical school that is rich in history and has its own special principles, elements, philosophy, and diagnostic and treatment options. Many complementary therapy modalities are also popular and in demand among patients and physicians. The aim of this paper is to provide logic for the policymakers in Iranian medical education to make changes in medical education curricula, particularly on integrating T&CM. Methods: We reviewed the global experience in teaching T&CM to medical students, and highlighting the strengths of PM, described why it is necessary to integrate T&CM into general medicine curricula in Iran. Results: PM is a traditional system of medicine that dates back about 7000 years. Although there are few studies about the safety and effectiveness of PM, research into it has recently been accelerated. There is a suitable opportunity for integrating T&CM with conventional medicine. Physicians should be familiar with T&CM to avoid any contraindications, interactions, and unwanted effects. Conclusion: Traditional medicine is part of Iran's heritage and. thus, needs special attention. Familiarization of physicians with T&CM can help them choose the best treatment options for their patients. To integrate T&CM into the medical education curricula of Iran, a two-credit course has been proposed for implementation across the country.

Investigation and evaluation of ultrasound reactor for reduction of fungi from sewage

引用

Journal of Zhejiang University-Science B(Biomedicine & Biotechnology) 2007年第7期8卷 493-497页

作者： DEHGHANI Mohammad Hadi MAHVI amir hossein JAHED Gholam Reza SHEIKHI Razieh Department of Environmental Health Engineering School of Public Health Medical Sciences/University of Tehran P.O. Box 14155-6145 Tehran I.R. Iran

The objective of the investigation was to study the application of ultrasound reactor technology (USRT) as a disin-fectant for reduction of fungi from sewage effluent. Fungi are carbon heterotrophs that require preformed organic compounds as carbon sources. USRT is an attractive means to improve water quality because of the system simplicity and no production of toxic by-products. An ultrasound reactor produces strong cavitation in aqueous solution causing shock waves and reactive free radicals by the violent collapse of the cavitation bubble. These effects should contribute to the physical disruption of microbial structures and inactivation of organisms. There was significant reduction in fungal growth, with decreased fungal growth with increasing USRT. In this study, ultrasound irradiation at a frequency of 42 kHz was used to expose suspensions of fungi to evaluate the disinfection efficacy of the ultrasound reactor. Also, this study showed that in this system more than 99% reduction of sewage fungi was achieved after 60 min.

Narrow solar-light response range and rapid charges recombination are the main technical barriers in TiO_(2) photocatalysis *** overcome these restrictions,in this work we synthesized a novel binuclear gadolinium(Ⅲ) coordination complex,[Gd_(2)(DPDB)_6(DMF)_6(H_(2)O_()2)](DPDB=[(4-dimethylamino)phenyldiazenyl] benzenesulfonate),which was used as an inorganic sensitizer for boosting the visible light-harvesting and quantum efficiency of TiO_(2) supported-reduced graphene oxide(rGO) *** structure of [Gd_(2)(DPDB)_6(DMF)_6(H_(2)O)_(2)](Gd-CMP) was determined from single-crystal X-ray diffraction data,which indicates three-dimensional(3D) supramolecular architecture through hydrogen bonding and CH…π_(ph) *** prepared nanohybrid(Gd-CMP/TG) reveals significantly enhanced visible-light-induced photocatalytic activity for degradation of acetaminophen(ACT).The complete removal of 10 mg/L ACT is achieved over Gd-CMP/TG,and the corresponding rate constant of ACT degradation of nanohybrid is 40-fold higher than that of bare TiO_(2).In prepared ternary nanohybrid,metal-coordination sensitizer(Gd-CMP) acts as an electron donor,and at the same time,rGO serves as an electron acceptor,and the synergistic effect between them efficiently enhances charges separation and inhibits e/h pair recombination in the hybridized *** radical scavenger tests indicate that the photo-induced O_(2)^(-·) radicals dominate ACT *** the basis of the experimental results and calculated energy of electronic levels,a possible mechanism for the improved photocatalytic activity is discussed.
