objective: to evaluate the efficacy of modified perihepatic packing (mphp) in reducing the rate of re-bleeding rate after packing removal. methods: this was an experimental study being performed in shiraz animal laboratory. high grade liver parenchymal injury was induced in 30 transgenic australian rabbits which were then divided into two groups. group a (control) included 14 and group b (exper...

To select the best available packing material for malodorous organic gases such as toluene and benzene, biofilter performance was compared in biofilters employed different packing materials including porous ceramic (celite), Jeju scoria (lava), a mixture of granular activated carbon (GAC) and celite (GAC/celite), and cubic polyurethane foam (PU). A toluene-degrading bacterium, Stenotrophomonas ...

BACKGROUND AND PURPOSE Endovascular coiling is a well-established therapy for treating intracranial aneurysms. Nonetheless, postoperative hemodynamic changes induced by this therapy remain not fully understood. The purpose of this work is to assess the influence of coil configuration and packing density on intra-aneurysmal hemodynamics. MATERIALS AND METHODS Three 3D rotational angiography im...

BACKGROUND AND PURPOSE The purpose of this study was to retrospectively compare the packing performance of helical Guglielmi detachable coil (GDC) 18 (thickness, 0.0135-0.015 inch) with the packing performance of both helical GDC 10 (thickness, 0.010 inch) and complex Trufill/Orbit coils (thickness, 0.012 inch). MATERIALS AND METHODS From our data base, we selected aneurysms that were exclusi...

the present paper describes the designing of a thermally and economically optimum mechanical draft counter-flow wet cooling tower. the design model allows the use of a variety of packing materials in the cooling tower toward optimizing heat transfer. once the optimum packing type is chosen, a compact cooling tower with low fan power consumption is modelled within the known design variables. mor...

the main issues in nasal surgery are to stabilize the nose in the good position after surgery and preserve the cartilages and bones in the favorable situation and reduce the risk of deviation recurrence. also it is necessary to avoid the synechia formation, nasal valve narrowing, hematoma and bleeding. due to the above mentioned problems and in order to solve and minimize them nasal packing, na...

Using atomistic molecular dynamics simulations we study solid and liquid crystalline columnar discotic phases formed by alkyl-substituted hexabenzocoronene mesogens. Correlations between the molecular structure, packing, and dynamical properties of these materials are established.
