METHODS: IRB approved retrospective review was conducted to identify consecutive implant-based reconstruction procedures performed at a tertiary academic medical institution by a single plastic surgeon over 15 years. Clinical endpoints of infection, seroma, hematoma, delayed wound healing, and explantation were recorded. Univariate analysis was conducted to compare patient characteristics acros...

  Background: Delay in diagnosis and treatment of perforated appendicitis may cause life-threatening complications. The aim of this study was to determine and compare pre-operative total and direct bilirubin levels in cases of simple and perforated acute appendicitis in order to improve the clinical decision making.   Methods: This prospective observational study included eighty patients who ...

Demand for and availability of blueberries has increased substantially over recent years, driven in part by their health-promoting properties. Three blueberry varieties ('Rocío', V2, and V3) were grown under two cultivation systems (open-field and plastic tunnels) and subjected to two irrigations regimes (100% and 80% of crop evapotranspiration) in two consecutive years (2011-2012). They were e...

Displacements around a tunnel, occurring as a result of excavation, consist of the elastic and plastic parts. In this paper, we discuss the elastic part of displacements as a result of excavation, called net displacement. In general, the previous analytical solutions presented for determining the displacements around a circular tunnel in an elastic medium do not give the net displacements...

Thin perforated Steel Plate Shear (SPS) Walls are among the most common types of energy dissipating systems. The applied holes reduce the shear strength of the plate and allow to decrease the profile size of the members at the boundary of the panel when these systems are used in the typical design of structures. On the other hand, the different fracture locations of these panels are visible whe...

Wen-Jei Yang Department of Mechanical Engineering and Applied Mechanics, The University of Michigan, Ann Arbor, Michigan 1 A n experimental study is performed to investigate the pressure drop distribution and turbulence intensity for airflow through a stack of parallel plates with periodic interruptions. The interrupted surfaces are constructed in an offset-strip f6rm and a perforated form. Hot...

The history of Laminar Flow Control (LFC) from the 1930s through the 1990s is reviewed and the current status of the technology is assessed. Early studies related to the natural laminar boundary-layer flow physics, manufacturing tolerances for laminar flow, and insect-contamination avoidance are discussed. Although most of this publication is about slot-, porous-, and perforated-suction LFC con...

The development of an effective evaluation method suitable for loess-tunnel excavation is necessary to avoid the collapse accidents caused by tunnel and any secondary disasters. Although Fenner formulas modified are widely used in engineering, a defect still exists these because Mohr–Coulomb (M–C) criterion exaggerates tensile strength surrounding rock loess tunnel. A newly formula was derived ...

humic acid, which has hormone- like activity , not only enhances plant growth and nutrients uptake but also improve stress tolerance. to determine the effect of humic acid on the yield and vegetative characteristics of tomato an experiment was conducted with tomato cv. `isabela` in 2008 in a plastic tunnel at the agriculture faculty, guilan university using randomized completely design with fou...
