Despite the widespread use of fibrous filtration media made up of trilobal fibers (referred to as trilobal media here), no mathematical formulations have yet been developed to predict their collection efficiency or pressure drop. In this study, we model the cross-section of a trilobal fiber with three overlapping ellipses separated from one another by a 120° transformation. We generate 2-D mode...

institutional repository or funder's repository and make it publicly available immediately. The favorable and adjustable transport properties of porous media make them suitable components in reactors used for solar energy conversion and storage processes. The directed engineering of the porous media's morphology can significantly improve the performance of these reactors. We used a multiscale a...

  A 29- year old female with bone pain and history of precocious puberty was referred for bone scintigraphy. On physical examination café au lait macular spots were noted on her neck, buttocks and left leg. Bone scan showed multiple areas of intense increased activity which was in favour of polyostotic fibrous dysplasia. Considering the presence of polyostotic fibrous...

Interactive media, especially the internet, are often used in an economic context where interactions are actually transactions. We focus on artists who apply economic principles and coin those works as “transactional arts”. We will observe that many accomplished new media works actually have transactional features and that the characteristics of the internet economy seem to facilitate this kind...

In this research, a novel method to decrease micro-residual stresses of fibrous composites by adding carbon nanotubes (CNTs) is proposed in detail. The negative coefficient of thermal expansion and the high young’s modulus of CNTs can be utilized to counterbalance the process induced residual stresses in composites. To this end, first, the effects of adding CNTs to the matrix of fibrous composi...

Abstract Several studies in the literature have been devoted to permeability prediction of metal foams and stacked fibres, including representative unit cell (RUC) model. This study is first involve a comparative analysis for specific surface area different versions RUC model fibrous media, i.e. 2D models in-plane through plane flow, 3D model, two-strut flow three-strut These are chosen due the...

purpose: to report the clinical and histopathological features of recurrent atypical fibrous histiocytoma of the corneo-scleral limbus followed by intra-epithelial squamous neoplasia. case report: a 25-year-old female patient presented with a recurrent vascularized gelatinous mass in the left nasal limbus. the preliminary histopathological diagnosis of the previously excised lesion was an amela...

717 ibrous dysplasia is a developmental anomaly that can affect any bone in the body. The skull and facial bones are the affected sites in 10–25% of patients with monostotic fibrous dysplasia and in 50% of patients with polyostotic fibrous dysplasia. Conventional radiographic findings reveal characteristics of fibrous dysplasia. CT findings also show characteristics of fibrous dysplasia and con...

Filtration media including woven cloths, nonwoven, membranes and particulate beds are used in a wide variety of applications such as biotech, health care, pharmaceutical, food and beverages, power sources and chemical industries. One way to characterise the performance of all these filtration media is by the pore structure characteristics of the media. Several experimental techniques are availa...
