An embodiment provides a method for treatment of a viral antigen for the COVID-19 virus, including: obtaining a body fluid from a patient; introducing the body fluid to at least one binding antibody, wherein the at least one binding antibody binds to an antigen of the SARS-CoV-2 spike (S) protein and comprises a conjugated metal; forming a viral antigen-antibody complex; and removing the viral antigen-antibody complex from the body fluid using a radiofrequency method; and returning the body fluid to the patient. Other aspects are described and claimed.

Treatment of wastewater and particularly relates to a technique for wastewater treatment using renewable energy (RE) which is sole solar energy (SE). In bench scale experiment, a device is constructed to consist of two fixed upper and lower glass Petri dishes. Another device consists of plastic containers and both devices with the same volume of wastewater in the upper and distilled water in the lower container. The first device is placed on the bench beside window to be exposed to sunlight at room temperature and the other device is put outdoors under direct sunlight during daytime. A build-up of small circular water droplets starts to appear on the external bottom of upper container. Water droplets are allowed to fall freely in the lower container, pH of droplets water is about 7.1. Yield of freshwater is at a rate of approximately 300 ml freshwater from 400 ml wastewater per 48 hours.

A system for relocating polluted air includes a tubular chamber with an inlet at one end, an outlet at a end, and auxiliary venturi inlets between the inlet and the outlet. There is at least one fan arranged within the tubular chamber. The fan flows air from outside of the tubular chamber, through the tubular chamber and out of the tubular chamber through the outlet. A compression chamber compresses air before entering the heating chamber. There is at least one heating element within the heating chamber. The heating element(s) heat the air, thereby increasing the velocity of the air through the tubular chamber. The air exits the tubular chamber through the outlet, directed vertically and upward towards upper strata of the atmosphere to redirect the air (and pollutants) into the upper strata of the atmosphere. In some embodiments, filters and scrubbers are provided within the tubular chamber for reducing pollutants.

An electronic apparatus includes a housing that includes an air inlet, and an air-intake duct section provided to supply air to the air inlet, and a filter housing that houses a filter provided to cover the air inlet, and moves toward the air-intake duct section in a thickness direction of the filter housing, to shift from a closed state in which the filter covers the air inlet to an open state in which the air inlet is uncovered.

An air conditioner including a frame, a fan operable to generate an airflow that moves in an airflow direction, and a first heat exchanger including a first end adjacent the air inlet, a second end adjacent the air outlet, an air inlet face that extends between the first end and the second end, an air outlet face that extends between the first end and the second end and faces opposite the air inlet face, and a longitudinal axis that extends through the first end and the second end between the air inlet face and the air outlet face. The heat exchanger is configured to transfer heat between the airflow and a cooling medium. A first heat exchanger angle is defined between the longitudinal axis of the heat exchanger and the airflow direction, and the first heat exchanger angle can be between about 3 degrees and about 20 degrees.
