Tricho-rhino-phalangeal syndrome type I (TRPS I) is characterized by a bulbous nose, sparse hair and epiphyseal coning. Autosomal dominant and recessive transmission are suggested. The presence of cone-shaped epiphyses, the major complaint of patients due to swelling over the phalangeal joints, requires differential diagnosis among various syndromes. This paper, describing a ten-year-old girl w...

This is a summary of state of the art horizontal well technology and a review of the economic benefits of horizontal wells. The paper describes various reservoir applications of horizontal wells from primary recovery to EOR applications. The paper includes field examples of different applications. . Although horizontal wells have been drilled as early as 1927, the major thrust of drilling horiz...

There are abundant bottom water reservoirs in China. Unlike conventional oil reservoirs, have various problems, such as early breakthrough, short water-free recovery period, and rapid cut increase. For example, during flooding, the injected easily breaks into does not effectively displace upper crude oil. The rate is generally low. Based on this phenomenon, an experimental study of nitrogen foa...

Abstract An oil well's productivity is generally considered the standard measure of performance. However, depends on several factors, including fluid characteristics, formation damage, reservoir's formation, and kind completion well undergoes. How a partial can affect performance will be investigated in detail this study, as nearly every vertical only partially completed result gas cap or water...

In this paper, new attitude maneuver using non-holonomic turn is proposed. The essence of this turn is characterized by an under-actuated system which does not have a direct torque device around the intended axis is made through what we call a coning motion. It is well known that falling cat motion utilizes non-holonomic turn. This paper shows the motion structure interpretation, in which a ver...

The problem of a spacecraft tracking a desired trajectory is defined and addressed using adaptive feedback control. The control law, which has the form of a sixth-order dynamic compensator, does not require knowledge of the inertia of the spacecraft. A Lyapunov argument is used to show that tracking is achieved globally. A simple spin about the intermediate principal axis and a coning motion ar...
