The operative procedure frequently used to narrow the nasal pyramid in the context of a regular rhinoplasty is well known to all rhinoplastic surgeons. It consists of hump removal, followed by lateral osteotomies and medialization of the nasal bones. However, narrowing of a wide nasal pyramid, in the absence of an appreciable dorsal hump, as in the case of an ideal dorsal height or a mild hump,...

intensively staffed facilities in the community. There was a sustained reduction in admissions but the gains appeared to plateau after the initial 2 years raising questions about the ongoing value of assertive outreach teams. As originally conceived, the teams’ intervention was intended to be indefinite and the argument made that gains would be lost once the service was withdrawn. However, this...

Background: Posterior tibial slope (PTS) is an important factor in the knee joint biomechanics and one of the bone features, which leads to knee joint stability. Posterior tibial slope affects flexion gap, knee joint stability and posterior femoral rollback that are related to wide range of knee motion. During high tibial osteotomy and total knee arthroplasty (TKA) surgery, proper retaining the...

conclusions in this case series study, the fixation of different types of tibial plateau fractures with 3.5 mm simple non-locking and non-precontoured plates was associated with acceptable clinical, functional, and radiographic outcomes. based on the advantages and costs of these plates, the authors recommend using 3.5 mm simple plates for different types of tibial plateau fractures. results th...

In this study, three-dimensional simulations of cone penetration tests (CPT) in cemented sandstone have been investigated using the Discrete Element Method (DEM). We generated realistic grain size distribution numerical Ustyurt-Buzachi Sedimentary Basin samples. Numbers CPT at different bond strength values were performed with penetrometer vertically moved down a constant rate. The results real...

this article addresses the phonetic and phonological representation of h- phrase accent in the tonal structure of persian pre-nuclear accents. in an experimental study, three groups of pre-nuclear accentual phrases, namely, phrases with antepenultimate, penultimate and final stress pattern, were selected for tonal examination. materials were designed so as to yield under-pressure and pressure f...

The relative impacts of different types of land use on the surface water quality are yet to be ascertained and quantified. In this paper, the influence of different types of land use on surface water quality is investigated. Rain events samples from different land use in the central plateau, Iran, were analyzed for major ions. Statistical analyses were employed to examine the statistical relati...

Background: The purpose of our study was to evaluate an inexpensive and available method to reduce mucous impactions in mechanically ventilated patients.Methods: This randomized clinical trial was conducted on 40 mechanically ventilated patients aged 15-90 years. The patients were randomly allocated into two arms; 20 cases and 20 controls. The cases received N-acetylcysteine via their nebulizer...
