Boost piezocatalytic activity of BaSO by coupling it with BaTiO, Cu:BaTiO, Fe:BaTiO, S:BaTiO and modify them by sucrose for water purification.

The purpose of this study is to improve the efficiency of decontamination using BaSO as a piezocatalyst. Three techniques are employed in this study to enhance the piezocatalytic activity of BaSO. The first method involves coupling BaSO with BaTiO.

Purification of wastewater by the piezo-catalyst effect of PbTiO nanostructures under ultrasonic vibration.

In this work, the piezoelectric catalytic property of PbTiO perovskite synthesized by a hydrothermal method has been investigated. The samples synthesized using no surfactant, lemon, orange, and watermelon as the surfactant. As-prepared PbTiO nanostructures as mechanical harvesting material were used to purify water containing organic contaminants.

A rare case of pulmonary Kaposi sarcoma presented with respiratory failure.

Kaposi sarcoma (KS) is the most commonly diagnosed malignancy in HIV-infected patients. With new treatments, incidence and severity of KS have significantly decreased. A 57-year-old African American male with medical history of AIDS presented with progressively worsening cough, shortness of breath, fever, night sweats, and 60 lb weight loss.

How to interpret the results of a sleep study.

With an increased level of awareness of sleep disorders among the public, there has been an increase in requests for sleep studies, and consequently, more referrals made to sleep specialists by primary care physicians and other health care providers. Understanding technical and clinical information provided in the sleep study report is crucial. It offers significant insight in to sleep pathophysiology in relation to patient symptoms.
