Introduction: Respiratory disorders pose a serious health risk for quarry workers exposed to dust, as they are a leading source of morbidity and mortality globally, often resulting in irreversible lung conditions. This study assessed the prevalence and determinants of restrictive disorder among quarry workers in Umuoghara quarry site, Ebonyi State.
Methods: This study was done on quarry workers at the Umuoghara quarry site, Ebonyi State.

Objective: Silicosis is a pneumoconiosis characterized by fibrosis of the lung parenchyma caused by the inhalation of silica particles. Silica dust inhalation is associated with inflammation and induction of oxidative stress in the lungs. This oxidative stress affects telomeres, which are short tandem DNA repeats that cap the end of linear chromosomes.

Coal workers' pneumoconiosis (CWP), a common subtype, varies in presentation from simple to complicated forms. Differential diagnosis is crucial, especially when CWP manifests as lung masses mimicking malignancy.

Autonomous vehicles, often known as self-driving cars, have emerged as a disruptive technology with the promise of safer, more efficient, and convenient transportation. The existing works provide achievable results but lack effective solutions, as accumulation on roads can obscure lane markings and traffic signs, making it difficult for the self-driving car to navigate safely. Heavy rain, snow, fog, or dust storms can severely limit the car's sensors' ability to detect obstacles, pedestrians, and other vehicles, which pose potential safety risks.

Background: Bird fancier's disease is a type of HP occurring due to exposure to bird's antigen. The diagnosis is quite difficult as it requires the identification of an inciting agent with findings of HRCT and lung biopsy. The exposure is usually done by history with antigen-specific IgG and/or specific inhalational challenge testing.
