the objective of the present study is the synthesis of mwcnt-tio2 hybrid nanostructures by solvothermal synthesis method with ticl4 as precursor. the heat transfer enhancement due to the use of mwcnt-tio2 nanofluid was investigated. as-prepared hybrid materials were characterized by x-ray diffraction (xrd) and scanning electron microscopy (sem). the results showed that mwcnts were uniformly dec...

mass vaccination against viral infections such as mumps is a very noticeable and appropriate attempt in common health. mumps infection has severe complications like deafness, infertility and meningitis. attenuated live vaccine of mumps is produced and used to prevent the problems. viral content in the monovalent vaccine is assayed with different methods. nowadays international standards introdu...

Presented is a study of the tripping strength of asymmetrical longitudinal plate stiffeners subjected to a combination of axial and lateral loads. The loaded edges were taken to be simply supported. The method of analysis is based on the principle of minimum total potential, and ten displacement functions were used to describe the deformations of the plate and stiffeners. First yielding was use...

For a human language to reach its full potential in cyberspace, platform and browser independent support for data entry and display are required. Arabic web applications are far from this state of ubiquitous support. Full support is available only under Arabic Windows, while little support is provided under other versions of Windows, and no support at all under UNIX systems .The Nuun toolkit ad...

With its ever growing popularity, providing Internet based applications tuned towards practical applications is on the rise. Advantages such as no external plugins and additional software, ease of use, updating and maintenance have increased the popularity of web applications. In this work, a web-based application has been developed which can perform size optimization of truss structure as a wh...

BACKGROUND Nail-bed injuries are the most common hand injury in children. Surgical dogma is to replace the nail plate after repairing the nail bed. Recent evidence suggests this might increase infection rates and returns to clinic. The aim of this feasibility trial was to inform the design and conduct of a definitive trial comparing replacing or discarding the nail plate after nail-bed repair. ...

Regional reference frames fixed to the stable part of a tectonic plate are often required for national spatial reference systems and to facilitate geophysical interpretation and inter-comparison of geodetic solutions of crustal motions. In 2003, the Stable North American Reference Frame (SNARF) Working Group was established under the auspices of UNAVCO and IAG Regional Sub-Commission 1.3c to ad...

BACKGROUND A web-based survey was conducted among Greek spinal surgeons to outline the current practice trends in regard to the surgical management of patients undergoing anterior cervical discectomy and fusion (ACDF) for degenerative cervical spine pathology. Various practice patterns exist in the surgical management of patients undergoing anterior cervical discectomy for degenerative patholog...

objective(s) studies have shown that morphine, in addition to its analgesic properties, has several effects on cell proliferation and apoptosis. there is also evidence that opioid receptors are present on chondrocytes. our main objective in the present study was to investigate the effects of morphine on rat femur growth cartilage. materials and methods this research was carried out on 18 4-week...
