Abstract:For timely prediction of the development of AHI syndrome in patients with closed abdominal trauma, it is necessary to monitor the IAP level. IBH syndrome develops in patients with concomitant abdominal trauma and is characterized by relatively high mortality rates. A statistically significant correlation was established between the level of AHI, APD, the frequency of development of a picture of multiple organ failure, and the severity of the patient’s condition according to the SOFA and APACHE II scales (p <0.05). A sudden increase and persistence of a high IAP level for a long time in patients with closed abdominal trauma indicate the use of active surgical tactics to perform decompression. The decision to decompress the abdominal cavity is based on IAP monitoring, considering the clinical picture of developing multiple organ failure.

Assessment of traumatic axial cervical spine injuries

Sarvar Akbarov Alisherovich

Abstract:Aim: To assess traumatic axial cervical spine injuries in 84 patients.
Methodology: Eighty-four patients with traumatic axial cervical spine injuries of either gender were enrolled. Magnetic imaging resonance (MRI) was performed in all. Conservative treatment was given to those with minimal no bony injuries with or without spinal cord contusion, and decompression and fixation were performed in moderate to severe bony injuries with spinal cord compression. In addition, patients were treated for anterior fixation, i.e., corpectomy with either autologous bone graft or titanium cage and plate fixation and with corpectomy with tricorticate graft.
Results: Out of 84 patients, males comprised 54 (64.2\%), and females had 30 (35.8\%). Aetiology in the present found to be assault in 9, road traffic accident in 48, sports injury in 17, and workplace injury in 10 cases. Body fracture was evident in 24 and ligamentous injury in 60 patients. The type of body fractures was C3 in 3, C4 in 2, C5 in 12, C6 in 3, and C7 in 4 patients. Management performed was corpectomy with tricorticate graft in 26 cases and a corpectomy with fixation with a titanium cage and plate/screws in 58 cases.
Conclusion: Discoligamentous was a major type of injury, and road traffic accident was the main cause of injury among patients with subaxial cervical spine injuries.

Algorithm analytic-numeric solution for nonlinear gas dynamic partial differential equation

EASL-Vol. 5 (2022), Issue 2, pp. 32 – 40 Open Access Full-Text PDF
Falade Kazeem Iyanda

Abstract: In this paper, we formulate a new seven-step algorithm using a modified new iterative method for the numerical solution of the nonlinear gas dynamics equation. Three test cases are considered to demonstrate the feasibility and efficiency of the proposed method. Furthermore, numerical solutions show a good agreement with analytical solutions and some available examples from the available literature.

Rethinking the halting problem-angles trisectability cryptographic analogy

EASL-Vol. 5 (2022), Issue 2, pp. 21 – 31 Open Access Full-Text PDF
Kimuya M. Alex and Munyambu C. June

Abstract: The “angle trisection-halting problem” impossibility analogy is fundamentally based on the obscure perception that; the classical geometric notion of constructability in Euclidean plane geometry corresponds to the modern theory of computability. Specifically, the difficulty of empirical trisectability of any angle has been viewed as analogous to the impossibility of solving the halting problem. The primary goal of this paper is to establish the inherent incompatibility between the geometric trisectioning of angles and the halting problem. The exposed proof concern the genetic solutions methodic characterization of the inconsistencies between the angle trisection problem and the halting problem. We show that regarding their attempts at solutions, the genetic trisectability of an arbitrary angle leads to solving the halting problem in geometric cryptographic schemes. It is upon the characteristic inconsistencies that we establish a provable refute of the validity of considering the practical applications of geometric cryptography as a solid source for cryptographic principles.
