abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Background: Esophagectomy is considered to be the main treatment for esophageal malignancies. Among the different methods, transhiatal approach can cause less damage to patients and is widely used however, manipulation of esophagus result in heart rate and blood pressure variations. The aim of this study was to investigate changes in blood pressure and heart rhythm during transhiatal esophagect...

Purpose This study examined the effectiveness of manipulation under ultrasound-guided brachial plexus block in patients with recalcitrant idiopathic frozen shoulder and diabetic secondary frozen shoulder (diabetic frozen shoulder). Methods Forty-four idiopathic frozen shoulders and 10 diabetic frozen shoulders with failed conservative treatment for at least 3 months were included in this stud...

Coordinated manipulation of micro-scale objects is critical for advancing several emerging applications such as microassembly and manipulation of biological cells. Most of the existing designs for micromanipulators are designed to accomplish primarily spatial positioning functionalities using positioning stages. Relatively, there are very few micromanipulators capable of ‘grip-and-place’ functi...

Many practical dextrous manipulation tasks involve large-scale motion of the grasped object while maintaining a stable grasp. To plan such tasks, one must control both the motion of the object and the contact locations, while also adhering to the workspace constraints typical of multingered hands. In this paper, we integrate the relevant theories of contact kinematics, nonholonomic motion plann...

[Purpose] To investigate effects of thoracic manipulation versus mobilization on chronic neck pain. [Methods] Thirty-nine chronic neck pain subjects were randomly assigned to single level thoracic manipulation, single level thoracic mobilization, or a control group. The cervical range of motion (CROM) and pain ratings (using a visual analog scale: VAS) were measured before, immediately after an...

Language spectfic editors, since they are cognisant of the syntax and semantics of the programming language they manipulate, -should provide a number of advantages for software developers. Howevel; they have not been widely accepted by software developers for serious soflware development. In other domains, such as drawing and VLSI design, direct manipulation editors (which are also cognisant of...
