A desiccant is a hygroscopic substance that absorbs water to preserve and protect products from the effects of moisture over time, often used with supplements and medications. They may have similar appearance, size, and shape to the desired medication or supplement. We present a case of an esophageal foreign body obstruction caused by unintentional ingestion of a desiccant. A 75-year-old man wi...

Along with the widely use in industries and lives, the dehumidification systems have consumed a large amount of energy. Fortunately, the application of liquid desiccant dehumidification system can greatly reduce the consumption of high-grade energy. To improve the advantages of liquid desiccant system compared with the conventional dehumidification system, one of the key measures is to increase...

An experimental investigation on the performance of a proposed hybrid desiccant based air conditioning system referred as HDBAC is introduced in this paper. HDBAC is mainly consisted of a liquid desiccant dehumidification unit integrated with a vapor compression system (VCS). The VCS unit has a cooling capacity of 5.27 kW and uses 134a as refrigerant. Calcium chloride (CaCl2) solution is used a...

Comfortable, efficient, and affordable heating, ventilation, and air conditioning systems in buildings are highly desirable due to the demands of energy efficiency and environmental friendliness. Traditional vapor-compression air conditioners exhibit a lower coefficient of performance (COP) (typically 2.8-3.8) owing to the cooling-based dehumidification methods that handle both sensible and lat...

Throat swabs are regarded as the "gold standard" for diagnosing streptococcal pharyngitis and for surveillance research. Culturing throats in remote tropical settings is logistically difficult, and these settings are commonly burdened by high rates of streptococcal disease. The survival of streptococci on swabs may depend on whether they are of "throat" or "skin" type, as determined by emm patt...

Dehumidifier is the most important unit in liquid desiccant air conditioning system. This paper experimentally investigates the performance of an adiabatic dehumidifier using calcium chloride as a liquid desiccant. The dehumidifier inlet parameters namely desiccant flow rate, concentration, temperature, air humidity ratio and liquid to air flow rate ratio, each at four levels have been chosen a...
