Permanent plots in indigenous forests administered by the Department of Conservation's West Coast Conservancy in the National Vegetation Survey (NVS) database were analysed to show which forest types were adequately sampled according to identifiable forest types, and within each type, in space and in time. From 404 permanent forest plots considered in analysis, eight forest types were determine...
Date of acceptance / Kabul tarihi: February 27, 2017 / 27 Şubat 2017 ABSTRACT: The mechanisms of recurrent laryngeal nerve injury during thyroidectomy and the impact of continuous intraoperative nerve monitoring on surgical strategy Objective: To evaluate the mechanisms of recurrent laryngeal nerve (RLN) injury during thyroidectomy and the impact of continuous intraoperative nerve monitoring (C...
background and aims. predicting the teeth eruption time is a valuable tool in pediatric dentistry since it can affects scheduling dental and orthodontic treatments. this study investigated the relationship between the eruption time of first primary and permanent teeth and the variation in the eruption time considering socioeconomic status (ses) in a 9-year population- based cohort study. materi...
Pre-stress techniques tend to increase cross-sectional capacity and optimize design. Such features have made these techniques rather popular. Over time, these structures tend to fail, and the reduction of pre-stress force over the lifetime of the structure is said to be one of the most significant destructive factors in these structures. This decrease in force occurs due to various reasons. In ...
Ground-based synthetic aperture radar (GBSAR) is a powerful tool used in monitoring structures, such as bridges and dams. However, despite the extremely short range of GBSAR interferometry, the atmosphere effects cannot be neglected. The permanent scatterer technique is an effective operational tool that utilizes a long series of SAR data and detects information with high accuracy. An algorithm...
Global Positioning System (GPS) technology with 10–20-Hz sampling rates allows scientifically justified dynamic measurements of relative displacements of long-period structures. The displacement response of a simulated tall building in real time and permanent deployment of GPS units at the roof of a building are described. To the authors’ best knowledge, this is the first permanent deployment o...
Diagnosing a power quality disturbance means identifying the type and cause of the disturbance. Fast diagnosis of power quality disturbances is important so as to assist network operators in performing counter measures and implementing suitable power quality mitigation actions. In this study a novel method for performing power quality diagnosis is presented by using the S-transform and rule bas...
OBJECTIVE The aim of this study was to evaluate osseous changes accompanying anterior repositioning splint (ARS) therapy in patients with temporomandibular joint disk displacement. STUDY DESIGN Cone-beam computerized tomography (CBCT) data of 36 patients with intermittent or permanent closed-lock were used; 23 patients with permanent closed-lock had their displaced disks physically reduced by...
This paper presents findings from on ongoing research study at the University of Illinois focusing on the instrumentation and performance monitoring of railroad bridge approaches using multidepth deflectometers and strain gauges. Different sensors installed at the selected approaches are introduced, and details of the instrumentation activity are explained. Example track settlement data acquire...
Underwater acoustic communication and networks have attracted significant attention in recent years, with applications ranging from ocean monitoring to off-shore sensor control, and port surveillance. Experimental data are required to test and develop effective underwater networking protocols before underwater networks can be successfully deployed for real world applications. Unfortunately, the...
