Building on organizational learning theory, we seek to identify the performance effects of security investments that arise from previous failures or external regulatory pressure. This study focuses on the healthcare sector where legislation mandates breach disclosure and detailed data on security investments are available. Using a Cox proportional hazard model, we demonstrate that proactive sec...

BACKGROUND Intra-organ and intra-vascular pressures can be used to estimate intra-abdominal pressure. The aim of this prospective, interventional study was to assess the effect of PEEP on the accuracy of pressure estimation at different measurement sites in a model of increased abdominal pressure. METHODS Catheters for pressure measurement were inserted into the stomach, urinary bladder, peri...

Recent advances in low power integrated circuits is opening up a whole new realm of possibilities in the field of medical implants. One such possibility is to have implants which require neither wires nor batteries. Such an implant could be put in place and monitored using external equipment for the life of the patient, and it would never require later surgical operations to replace the batteri...

in this paper, the deformation of a thick-walled circular cylindrical shell of incompressible isotropic elastic material is considered. the shell, which is made of three-term strain energy function is subjected to the combined external and axial loading pressure. in order to obtain the relevant eigenvalues, which is the main objective of the work, the incremental equilibrium equations are so...

Abstract   In this paper analytical analysis of capacitive pressure sensor with clamped diaphragm is presented. Mechanical and electrical properties of the sensor are theoretically analyzed based on theory of thin plates with small deflection and the results are evaluated by use of finite element analysis. The central deflection and capacitance values under uniform external pressure are calcula...

BACKGROUND The military medical community has promoted use of Foley catheter balloon tamponade in the initial management of vascular injury owing to neck or maxillofacial trauma. The aim of the study was to compare outcomes with Foley catheter tamponade with those obtained with traditional use of external pressure. METHODS This retrospective cohort study evaluated all cases of persistent blee...

This study examined the prevalence of external, restrained and emotional eating and the relationship of these disturbed types of eating behaviours with perceived parental control of food intake (pressure to eat and restriction) in a group of 7- to 12-year-old boys and girls (n = 596). External eating turned out to be the most prevalent disturbed eating behaviour for boys and girls, followed by ...

BACKGROUND Combined pelvic floor electromyography (EMG) and videocystourethrography (VCUG) during urodynamic investigation are the most acceptable and widely agreed methods for diagnosing detrusor external sphincter dyssynergia (DESD). Theoretically, external urethral sphincter pressure (EUSP) measurement would provide enough information for the diagnosis of DESD and could simplify the urodynam...

Manipulation of interstitial fluid pressure (IFP) has a clinical potential when used in conjunction with near-infrared spectroscopy for the detection of breast cancer. In order to better interpret how the applied pressure alters the vascular space and interstitial water volumes in breast tissue, a study on tissue-mimicking, gelatin phantoms was carried out to mimic the translation of external f...

In this paper, thermo-elastic analysis of a rotating thick truncated conical shell subjected to the temperature gradient, internal pressure and external pressure is presented. Given the existence of shear stress in the conical shell due to thickness change along the axial direction, the governing equations are obtained based on first-order shear deformation theory (FSDT). These equations are so...
