 Methods: Membership data 2021 American Academy Dermatology (AAD) database were retrieved characterize 3-digit zip code areas.
 Results: Out 712 populated codes wit...

BACKGROUND Although it is commonly assumed that pulmonary congestion and edema in patients with chronic heart failure (CHF) promotes peripheral airway closure, closing capacity (CC) has not been measured in CHF patients. PURPOSES To measure CC and the presence or absence of airway closure and expiratory flow limitation (FL) during resting breathing in CHF patients. METHODS In 20 CHF patient...

BACKGROUND The availability and distribution of an appropriate eye care workforce are fundamental to reaching the goals of "VISION 2020: The right to sight", the global initiative for the elimination of avoidable blindness launched jointly by the World Health Organization and the International Agency for the Prevention of Blindness with an international membership of nongovernmental organizatio...

The hybrid control, as proposed by Kim et al. (2008), employs a primary expansion valve that provides most of the pressure drop, while small secondary balancing valves in the distributor lines to the circuits of the evaporator adjust the refrigerant flow to provide equal circuit exit superheats. This paper shows the experimental results for the application of the hybrid control of expansion val...

Operating the fluid catalytic cracking unit (FCCU) in afterburning conditions can increase regenerator temperatures above metallurgical design leading to mechanical failures of cyclones and plenum chamber. This paper presents methodology applied a commercial FCCU investigate causes technical solutions that be implemented reduce afterburning. Thus, by evaluating temperature profile, as-build des...

A novel concept called volatiles distributor (VD), with the purpose to achieve an even distribution of over cross-section a fluidized-bed and better contact between bed materials, has been investigated. The could be useful for chemical- looping combustion, as well other solid fuel conversion processes in fluidized-beds. An experimental study VD circulating (CFB) cold-flow model was conducted un...

Fluid imbalance can arise due to hypovolemia, normovolemia with maldistribution of fluid, and hypervolemia. Trauma is among the most frequent causes of hypovolemia, with its often profuse attendant blood loss. Another common cause is dehydration, which primarily entails loss of plasma rather than whole blood. The consequences of hypovolemia include reduction in circulating blood volume, lower v...
