The systemic pharmacological treatment of disease is limited by severe toxicity to normal organs/tissue. Therefore, various delivery vehicles have been designed to carry therapeutic drugs to their target tissues. We designed a novel vehicle formed by the interaction of biotins in a DNA (polymer) with avidins (crosslink), resulting in a porous particle. This self-assembled (HSAM) nanoparticle ve...
هدف: با توجه به اهمیت پژوهشهای بین رشتهای، این پژوهش با هدف مطالعه رابطع شاخصهای مرکزیت با بهرهوری علمی و کارآیی پژوهشگران حوزه آموزش از دور انجام شده است. روش: پژوهش از نوع مطالعات کاربردی علمسنجی است که از فن تحلیل شبکههای اجتماعی استفاده میکند. جامعه آماری پژوهش 40252 مدارک علمی پژوهشگرانی است که در پایگاه ISI از 1992 تا 2012 نمایه شده است. برای تحلیلهای شبکهای و آماری از نرمافزار...
DEA methodology allows DMUs to select the weights freely, so in the optimalsolution we may see many zeros in the optimal weight. to overcome this prob-lem, there are some methods, but they are not suitable for evaluating DMUswith fuzzy data. In this paper, we propose a new method for solving fuzzyDEA models with restricted multipliers with less computation, and comparethis method with Liu''''''...
Facebook is the most dominant social networking site in colleges right now. According to a recent study done by OnlineEducation.net on college students' use of social media in the U.S., 96 percent of college students use Facebook. In addition, 75 percent of college students report that they want to collaborate online with each other via Facebook (Andrew, 2011). Because of the popularity of Face...
fundamentally from its desktop or Internet counterparts. Embedded computing is not simply computation on small devices. In most control applications, for example, embedded software engages the physical world. It reacts to physical and user-interaction events, performs computation on limited and competing resources, and produces results that further impact the environment. Of necessity, it acqui...
The prevalence of Toxoplasma gondii infection in free-range chickens in Jilin province, northeastern China was investigated. A total of 1095 serum samples were collected from nine administrative regions from July to October, 2012, and antibodies to T. gondii were examined by an in-house enzyme-linked immunosorbent assay (ELISA) using Toxoplasma lysate antigen (TLA). The detection results were c...
