In this paper, we study the existence of normalized solutions to the Klein-Gordon-Maxwell systems. In the mass-subcritical case, we prove that the systems satisfying normalization conditions have a normalized ground state solution.

Hernia is a condition in which part of an organ is displaced and protrudes through the wall of the cavity containing it. A spigelian hernia is a rare type of ventral hernia, principally acquired. Surgery is the only way to treat a spigelian hernia, either by a regular surgical operation or through laparoscopic repair. We present the parietal repair of a large spigelian hernia by muscle plasty and placement of a plate in a 59-year-old patient. The patient had an abdominal ptosis and a surgical hi...

Another decade passed and Pygmalion appeared again as an actual character in Back to Me...

Whole blood resuscitation has emerged as a promising alternative to conventional component therapy for patients in hemorrhagic shock. Animal studies and clinical evidence in both civilian and military populations have shown improved outcomes with whole blood. While further research is needed to establish optimal patient selection criteria, dosing, and transfusion practices, the use of whole blood in resuscitation has the potential to save lives and improve outcomes. Whole blood provides balanced...

Balint’s syndrome is a rare neurological disorder, characterized by simultanagnosia, ocular apraxia and optic ataxia. The lesion is usually inside the parietooccipital region bilaterally in most cases. We report a 51-year-old man presenting a primary diffuse large B-cell lymphoma revealed by Balint syndrome. The patient showed improvement in the first month after the start of chemotherapy.

Currently, the teaching of collage English listening generally adopts a combination of classroom teaching and online autonomic learning. Due to various factors, the effectiveness often fails to meet expectations. This study takes the “Teacher Student Collaborative Assessment” (TSCA) model as the blueprint and constructs an autonomic learning plan based on teacher-student negotiation and cooperation. Through a series of measures such as collaborative learning plans, regular spot checks and feedba...

In order to reduce environmental pollution and associated health risks, managing empty pesticide containers is a crucial part of agricultural waste disposal. The open-burning method and the triple rinsing method, two regularly used approaches to empty pesticide container management, are compared in this study. Empty pesticide containers are burned using the open burning technique to reduce their volume and make disposal easier. On the other hand, the triple rinsing method focuses on washing pest...

This research uses the Life Cycle Assessment methodology to assess the environmental impact of Cameroon’s thermal power production technology. Thus, for Heavy Fuel Oil (HFO), Light Fuel Oil (LFO), and gas technologies, the Green House Gas equivalent emission factor values are 873 g/kWh, 944 g/kWh, and 577 g/kWh, respectively. These figures are much higher than the IEA-reported emission factor of the Cameroonian power mix, which is 207 g of CO₂-eq per MWh. On average, these technologie...
