Garbage and biomass contain more chlorine, which reacts with H to form HCl gas during combustion or gasification, resulting in corrosion of metal walls. In this paper, based on the chlorine mechanism in Ansys Chemkin-Pro, the laminar combustion characteristics of H/Cl are simulated with different diluents CO/N under an initial temperature of 298 K, equivalence ratio range of 0.6-1.4, and initial pressure of 0.1-0.5 MPa. The results show that the laminar burning velocity of H/Cl decreases significantly with the increase of dilution gas ratio, and the effect of diluent CO is more significant than that of N. Due to the dilution effect, the fuel and oxidation components are reduced. Through sensitivity analysis, reaction R2: Cl + H = HCl + H is the main reaction of HCl formation. On improving the initial pressure, the laminar burning velocity is slightly lowered, and the thermal diffusivity of the fuel mixture increases with the increase of the initial pressure. According to the sensitivity analysis of the velocity, reactions R2, R9, and R10 are the main reactions that affect the laminar burning velocity, and the product HCl will be generated with a delay with the increase of the initial pressure.

Background: Patients with cervical spinal cord injuries (CSCIs) have a high incidence of respiratory complications. The effectiveness of non-invasive positive pressure ventilation (NPPV) in preventing respiratory complications such as pneumonia in acute CSCIs remains unclear. We evaluated whether intermittent NPPV (iNPPV) could prevent pneumonia in patients with acute CSCIs.

Introduction: Pelvic fractures often result in life-threatening bleeding and hemodynamic instability. Resuscitative endovascular balloon occlusion of the aorta (REBOA) has emerged as a promising strategy for patients with severe pelvic fractures, facilitating subsequent hemostatic interventions. Transcatheter arterial embolization (TAE) is a well-established procedure for managing pelvic fractures accompanied by hemorrhage.

Immunologically inert or cold tumors pose a substantial challenge to the effectiveness of immunotherapy. The use of oncolytic viruses (OVs) to induce immunogenic cell death (ICD) in tumor cells is a well-established strategy for initiating the cancer immunity cycle (CIC). This process promotes the trafficking and infiltration of CD8+ T cells into tumors, thereby eliciting a tumor-specific immune response.

Introduction: Despite dramatic advances in the care of trauma patients over the last fifty years, cardiac stab wounds (CSW) remain highly lethal, and the specific relationship between serum lactate level and mortality is unknown.
Methods: A retrospective review was conducted on all patients who presented with intraoperatively confirmed CSW from January 2008 to January 2020 at a major trauma centre in South Africa. Admission serum lactate level and patients' clinical outcomes were reviewed.
A Complex, Convexity, Anterior Superior Sagittal Sinus Dural Arteriovenous Fistula Secondary to Venous Sinus Thrombosis.

Neurosurgery, Queens Hospital Center, Romford, GBR.
We report the management of a convexity dural arteriovenous fistula (dAVF) in an uncommon anterior superior sagittal sinus (SSS) location. This was a high-risk Cognard IIa+b dAVF, which is notoriously complex to treat. Endoscopic management alone for complex SSS dAVFs is challenging due to the often bilateral arterial supply to the fistula, as demonstrated in this case.
