Abstract: This paper presents the results of experimental determination of fiber bed permeability variation with porosity. Flow measurement experiments were designed to measure fiber mat permeability for fiber beds with various fiber volume fractions. Woven fiberglass, chopped fiberglass, and carbon fiber mats were used as reinforcements. The effects of reinforcement type and porosity on fiber ...
در این پایان نامه یک مدل برآورد هزینه های ادواری جهت برآورد هزینه عرشه های ساخته شده از ترکیبات fiber reinforced polymer(frp) ارائه شده است. این مدل تمامی هزینه های کارفرما، هزینه های بهره بردار و هزینه های طرف سوم را در جهت تخمین و برآورد هزینه های ادواری عرشه های frp در دوره عمر مفید پل در نظر می گیرد.

background and aims. the aim was to evaluate the effect of three methods of fiber insertion on fracture resistance of root-filled maxillary premolars in vitro. materials and methods. sixty extracted human maxillary premolars received endodontic treatment followed by preparation of mesioocclusodistal (mod) cavities, with gingival cavosurface margin 1.5 mm coronal to the cementoenamel junction (c...
an experiment was carried out to develop and evaluate a semi-purified diet suitable for fiber related studies without negative impacts on performance, serum biochemistry and intestinal morphology of growing japanese quails. total of 144 japanese quail chicks were used in a factorial arrangement using completely randomized design with 6 treatments, 4 replicates of 6 quails in each replicate. the...
Irregularities are inherent to virtually all fibers, including the conventional textile fibers, the high-performance brittle fibers and newly developed nano-fibers. These irregularities can fall into two main categories: dimensional or geometrical irregularity (external) and structural irregularity (internal). For natural fibers such as wool, diameter variation along fiber length is atypical ex...
