This paper presents the results of 150 finite-element simulations conducted to define effects excavation geometry, i.e., length, width, and depth excavation, wall system stiffness, factor safety against basal heave on three-dimensional ground movements caused by through clays. The analyses are represented plane strain ratio (PSR), defined as maximum movement in center an computed normalized that a simulation. A simple equation for PSR is presented based heave. reasonably represents trends...

Predicting building damage due to ground movements caused by excavations is an important design consideration when in a congested urban environment. Current predictive approaches range from empirical methods detailed finite element calculations. Limitations inherent the simpler of these models preclude them accurately predicting cases where assumptions are invalid. A new simple model for representing buildings presented allow designer make realistic simplifications system that consistent...

Several three-dimensional effects were observed in the performance monitoring data collected during excavation for Ford Engineering Design Center Evanston, Illinois. The elevations of soil around varied and excavator removed a nonuniform process, both which contributed to (3D) effects. This paper describes support system subsurface conditions at site, summarizes construction procedures, presents lateral movements measured by inclinometers, ground-surface an automated total station, tilt...

Abstract Background Cyberchondria may be defined as heightened distress evoked through excessive searches of the internet for medical information. In healthy people, cyberchondria is associated with a greater intolerance uncertainty and health anxiety. These relationships are likely bidirectional. People who have more to search information This anxiety lead an increased likelihood engaging in further uncertainty. three constructs important patients because they impact patient function care...

A life-cycle sustainability assessment evaluated and compared the impacts of five ground improvement methods commonly implemented to mitigate liquefaction: compaction grouting, deep dynamic compaction, soil mixing, vibro replacement (i.e., stone columns). Using typical scopes work provided by geotechnical contractors who specialize in improvement, this study developed benchmarks for costs each method, quantified consequences risk uncertainty inherent projects, examined land resources that...

The purpose of this study was to investigate if there were any significant differences in the long-term outcomes patients who participated a randomized trial trapeziectomy alone compared with ligament reconstruction and tendon interposition (LRTI). Sixty-five invited for follow-up visit at mean 17 years (range 15–20) postoperatively. Twenty-eight attended, had 34 operations, 14 20 LRTI. There no statistically between two groups terms satisfaction surgery or functional outcomes, most...

Psychological factors such as depression, pain catastrophizing, kinesiophobia, anxiety, and more negative illness perceptions are associated with worse function in patients at the start of treatment for de Quervain's tenosynovitis. Longitudinal studies have found symptoms depression catastrophizing baseline were after treatment. It is important to study opting surgery their condition because should choose surgical based on values rather than misconceptions. patient-reported outcomes from...

Abstract Background Depression, anxiety, and pain catastrophizing have been associated with worse function in studies of patients de Quervain’s tenosynovitis. Illness perceptions are the patient’s thoughts feelings about their illness. More negative illness such as having a long duration or serious consequences physical hand osteoarthritis. It is currently unknown whether these psychological factors play similar role Quervain’s. We chose to study who tried nonoperative management chosen...

In this cohort study, we report on short-term outcomes of 203 patients (203 wrists) who underwent scapholunate ligament reconstruction using a three-ligament tenodesis technique between December 2013 and 2017. Patients completed the Patient Rated Wrist Evaluation questionnaire visual analogue scale for pain online before surgery at 3 months 1 year after surgery. We also measured range movement surgery, in 150 90 The reported clinically significant improvements both function postoperatively,...

This paper describes remote and automatic monitoring systems for measuring vertical horizontal displacements tilt of structural elements. An automated total station system tiltmeters were employed at the excavation Ford Engineering Design Center. The 9.1-m-deep was made through fill soft clays undercut shallow foundations a building 6 m from edge excavation. support consisted sheet pile wall supported by two levels cross-lot diagonal internal bracing. systems, construction details are...

Introduction Most total hip arthroplasties (THAs) in the UK are performed through a posterior or lateral surgical approach. We aimed to investigate any difference outcome from revision THA according approach at primary and surgery. Methods A retrospective cohort study of 205 patients who underwent for aseptic loosening. Patients rated their pain 0-10 completed Self-Administered Patient Satisfaction Scale (SAPS), Oxford Hip Score (OHS), WOMAC Short form-12 questionnaires. Results (209 hips)...

Background and purpose - Patient-reported outcome measures (PROMs) are used to understand better the outcomes after total hip replacement (THR). These administered in different settings using a variety of methods. We investigated whether mode delivery commonly PROMs affects reported scores, 1 year THR. Patients methods A prospective test-retest comparison study with randomized sequence was done 66 patients who had undergone primary were by 4 modes: self-administration, face-to-face...

An outbreak of tuberculosis caused by Mycobacterium avium type 2 is described which resulted in the total condemnation 26 carcasses and partial tissues organs a further 200 animals. Circumstantial evidence presented that hens running farmyard were source infection. Examinations diseased pigs suggested accepted pathogenesis disease incorrect new hypothesis presented. The problems for meat inspector differentiating from 'milk-spot liver' are discussed recommendations made. findings study light...

Three-dimensional finite element analysis is combined with field and laboratory measurement of time domain reflectometry (TDR) cable-grout response to analyze the interaction between cable, grout, surrounding soil mass during localized shearing. Finite (FE) model parameters for cable interface elements are back-calculated by matching results from shearing tests FE calculated response. These employed in subsequent geometries behavior TDR composites soft soils. Optimal grout design determined...

Excavation projects related to urban redevelopment and infrastructure improvement are often governed by serviceability-based design, rather than failure prevention criteria. Deformation tolerance specifications prescribed based on minimizing potential damage adjacent structures. A risk-based approach serviceability performance that systematically incorporates design parameter uncertainty will allow engineers address soil in performance-based design. This paper demonstrates the use of various...

Background Excision of the pisiform is an infrequently used option for pisotriquetral joint dysfunction when nonoperative treatment ineffective. This study reviews patient-reported outcomes patients treated with pisiformectomy, and furthermore focuses on complications need time to revision procedure. Materials Methods Medical records 57 were manually reviewed assessed complications, rate unplanned reoperations, type reoperations. Thirty-seven (65%) completed patient-rated surveys at a median...

Background: The clinical picture of ulnar-sided wrist pain is oftentimes confusing because various pathologies may be coexistent. In this study, we aimed: (1) to compare the prevalence potential causes on magnetic resonance imaging (MRI) in patients who underwent triangular fibrocartilage complex (TFCC) repair and control subjects: (2) evaluate whether inferior results were associated with specific patient characteristics or other pain. Methods: We included 67 a TFCC subjects. MRI scans...
