Press Conduction Welding for Secondary Bonding of Aircraft Skin/Stiffener Assemblies Using Carbon Fiber/PEKK Thermoplastic Composites and PEI Adhesive.

This study investigates the secondary bonding of aircraft skin/stiffener assemblies using press conduction welding with carbon fiber/polyetherketoneketone thermoplastic composites and polyetherimide adhesive. Recognizing the challenges posed by conventional welding methods in maintaining material integrity and uniformity, this research explores an alternative methodology that mitigates these issues while ensuring high-strength bonds. The press conduction welding parameters were selected based on single-lap shear tests and applied in the bonding of skin and omega stiffener components.

Laparoscopic duodenal segmental resection and duodenojejunostomy for symptomatic duodenal diverticula in three cases treated at a community hospital.

The duodenum is the second most common site of diverticula following the colon, but is associated with fewer complications than colonic diverticula. Diverticulitis, cholangitis, pancreatitis, perforation, hemorrhage, and blind loop syndrome may occur as complications of duodenal diverticula. Although nonoperative treatment is an option for patients in good condition without signs of sepsis, surgery is generally required for definitive treatment of complications.

Risk factor, monitoring, and treatment for snakebite induced coagulopathy: a multicenter retrospective study.

Background: Snakebite can cause various complications, including coagulopathy. The clinical features of snakebite-associated coagulopathy differ from those of disseminated intravascular coagulation (DIC) caused by other diseases and its treatment is controversial.

Methods: We retrospectively reviewed the medical records of patients hospitalized for snakebite between January 2006 and September 2018.

Electrochemiluminescent chemodosimeter based on iridium(III) complex for point-of-care detection of homocysteine levels.

Elevated levels of plasma homocysteine (Hcy) are an independent risk factor for cardiovascular disease. Although a routine, rapid, and simple determination of Hcy levels is highly desired, the existing methods are practically limited because of complicated sample preparation and bulky instrumentation. Herein, we report a chemodosimetric approach for one-step analysis of Hcy levels based on the electrochemiluminescence (ECL).
