Background and Aim: Spinal manipulation is a treatment modality in the management of patients with pain in the neck, low back or pelvic disorders. The objective of this research was to determine the effects of sacroiliac joint manipulation on selected electrophysiological parameters including pressure pain thresholds (PPT) and Tibial nerve Hoffmann's reflex (H-reflex) amplitude. Materials and M...
We investigate an angular variation of pressure at a laser-induced shock front in a liquid filled thin tube. We adopt the background-oriented schlieren (BOS) technique. This technique enables us to measure twoor three-dimensional pressure field in a small region with a simple setup. We obtain the spatiotemporal evolution of the pressure field thanks to an ultra high-speed video camera and a las...
a non-linear finite element model could be a useful tool in the development of a method of predicting soil pressure-sinkage behaviour, and can be used to investigate and analyze soil compaction. this study was undertaken to emphasize that the finite element method (fem) is a proper technique to model soil pressure-sinkage behaviour. for this purpose, the finite element method was used to model ...
In this paper a novel zoom-based technique with pressure (hereafter referred to as “ZWPS”) is proposed to improve small target selection in penbased interfaces. In this technique pressure is used as a switch mode to couple a standard pointing technique and a zoomable technique together. ZWPS allows both precise and normal selections. We conducted an experiment to examine the effectiveness of ZW...
Background and Importance: Overdrainage is a complication of ventriculoperitoneal shunt but adjustable valves and anti-siphon devices can prevent it. These very expensive valves are most often inaccessible, so that the majority of the valves available in Togo are fixed differential pressure valves. Although overdrainage is a widely-known issue, we aimed to introduce a new risk factor and the wa...
Introduction: This study aimed to evaluate the effects of four-time inflation of the stent balloon at nominal pressure on optimal stent expansion in resistant lesions. Materials and Methods: This interventional study was conducted on 39 patients with coronary artery lesions, in whom Zotarolimus-eluting stents (N=20), Paclitaxel-eluting stents (N=11) and other stents (N=8) were deployed four tim...
This article describes the clinical procedures for a modified putty-wash impression technique. In this method, the hydraulic pressure induced from planned flowing the wash material from the inner surface of putty impression toward the vestibules pull over the gingival tissues covering the finishing line. This simple method reduces the need to using retraction cord in normal depth finishing line...
BACKGROUND Equipment, physiologic, and technique factors can influence the accuracy of blood pressure measurement. The current study was designed to isolate certain technique factors and then assess the accuracy of nursing personnel measurements of blood pressure in three residency family practice centers. METHODS An experienced registered nurse was trained in applying the American Heart Asso...
Introduction & Objective: Percutaneous Dilatational Tratheostomy (PDT) is an elective procedure increasingly performed at bedside in intensive care unit (ICU). With this technique the complications during transferring to the operating room, duration between one patient candidate for PDT to perform it and cost decreased compared to the standard technique. In our study we compared the duration ...
Introduction: Cardiovascular diseases are the most common cause of death in the most countries and Iran, and are the main disability cause, those induced stress, anxiety and changes in vital signs in patients under coronary artery bypass graft (CABG) surgery. This study was conducted to determine the effect of progressive muscle relaxation on the vital signs and oxygenation indexes of patients ...
