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...

Seventy-four patients with proved spontaneous subarachnoid haemorrhage were studied. Sixty-four underwent computed tomography and 55 underwent lumbar puncture. Seven cases deteriorated dramatically after lumbar puncture, six of these showing evidence of cerebral dislocation on further investigation. Four of the seven had not undergone computed tomography and three underwent computed tomography ...

Objectives. To highlight the importance of early diagnosis of colloid cyst of the third ventricle and its early management. Clinical Presentation and Intervention. This is a young lady who presented with sudden onset headache. She attended a local clinic and also her area hospital. Her diagnosis was delayed several hours due to a diagnostic dilemma initially. No surgical intervention was tried ...

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...

Recent results have confirmed that the global rigidity of bar and joint frameworks on a graph G is a generic property in Euclidean spaces of all dimensions. While this creates the possibility of a combinatorial characterization of genericaly globally rigid graphs, the only current combinatorial characterizations, which are known to be deterministically computable in polynomial time, are in dime...

In the Niger Delta, low oil recovery rates less than 30% results mainly due to production problems such as water coning, wax deposition and high gas/oil ratios. Meanwhile, remaining becomes a good candidate for EOR methods CO2 injection, polymer foam in-situ combustion steam injection. But it stands, practice of these known enhanced is scarce in Nigeria’s Oil Gas industry. However, this project...
