Background: With the discovery of the Pre-Salt oil deposits, the exploration of oil and gas is being extended to great depths in Brazil, thereby generating increasing demand for drilling capabilities. Objective: This article is aimed at assessing the consequences of this discovery accomplished by Petróleo Brasileiro S.A. (Petrobras) on patent applications in Brazil related to drilling fluid technologies. Methods: In essence, our stud Read More

Background: In recent years, the researches and developments on skull grinding to remove bone pathology are increasing. Clinically, the neurosurgeons usually treat skull based lesions by removing bone pathology with high speed grinding wheel. Nevertheless, high speed grinding produces a large amount of heat, which causes thermal damage to surrounding tissues and bone necrosis. The highest critical temperat Read More

Background: Nanotechnology, as the branch of technology that deals with dimensions and tolerances of less than 100 nanometers, especially the manipulation of individual atoms and molecules, has implications on scientific, medical and economic and legal impacts on society. There are extensive researches in the nanotechnology and these studies have led important discoveries in the area of nanorobotics. Objective: Th Read More

Background: Ni(II) removal from water environment is very important because it is very toxic. There are many conventional methods for Ni(II) removal but many of them have high operational and maintenance cost. Adsorption is a treatment process which is highly effective, cheap and easy to adopt. Objective: The goal of this work is to develop a suitable adsorbent for Ni(II) removal and determine the optimal condition Read More

Background: This article reviews recent patents pertaining to the technological achievements and shortcomings of aircraft Position Indicator and Actuator System (PIAS). Generally, most patents have concentrated more on design, while implementing various developed single or multiobjective algorithms to solve component or system optimal design problems such as those of PIAS. Thus, there is a noticeable lack of patent effor Read More

Background: Stiffened plates are commonly used in many engineering applications. Engineers in practice encounter many challenges in the analysis and design of stiffened plates due to the modelling complexities and many parameters involved. Little guidelines are available in industrial codes of practice for the design of stiffened plates. This article reviews recent developments and patents related to analysis and design Read More

Background: Loop Seal is a key component in circulating fluidized bed. It is necessary to study its internal flow rules. Diameter of solid particle in Loop Seal is too large or small can produce bigger effects for fluidized bed operation. Objective: We will study internal flow rules in Loop Seal, and look for relationship between the key parameters of solid particle circulation and particle diameter by cold experiment. Method: The col Read More
