Ultrasound-assisted regeneration of activated alumina/water adsorption pair for drying and dehumidification processes.

Desorption processes are important part of all processes which involve utilization of solid adsorbents and are inherently energy-intensive. Here we investigate how those energy requirements can be reduced through the application of ultrasound for the activated alumina/water adsorption pair. To analyze the energy-saving characteristics of ultrasound, the ultrasonic-power-to-total power ratios of 0.

The Emirates Mars Mission (EMM) Emirates Mars InfraRed Spectrometer (EMIRS) Instrument.

The Emirates Mars Mission Emirates Mars Infrared Spectrometer (EMIRS) will provide remote measurements of the martian surface and lower atmosphere in order to better characterize the geographic and diurnal variability of key constituents (water ice, water vapor, and dust) along with temperature profiles on sub-seasonal timescales. EMIRS is a FTIR spectrometer covering the range from 6.0-100+ μm (1666-100 cm) with a spectral sampling as high as 5 cm and a 5.

Ultrasound-assisted regeneration of zeolite/water adsorption pair.

The use of ultrasound to enhance the regeneration of zeolite 13X for efficient utilization of thermal energy was investigated as a substitute to conventional heating methods. The effects of ultrasonic power and frequency on the desorption of water from zeolite 13X were analyzed to optimize the desorption efficiency. To determine and justify the effectiveness of incorporating ultrasound from an energy-savings point of view, an approach of constant overall input power of 20 or 25 W was adopted.

Development of a Surveillance Definition for United States-Mexico Binational Cases of Tuberculosis.

Objectives: Consistently collected binational surveillance data are important in advocating for resources to manage and treat binational cases of tuberculosis (TB). The objective of this study was to develop a surveillance definition for binational (United States-Mexico) cases of TB to assess the burden on US TB program resources.

Methods: We collaborated with state and local TB program staff members in the United States to identify characteristics associated with binational cases of TB.

Flouroscopic arthrography versus MR arthrography of the lesser metatarsophalangeal joints for the detection of tears of the plantar plate and joint capsule: a prospective comparative study.

Background: Derangements of the plantar plate and joint capsule are an underrecognized cause of lesser metatarsalgia. Fluoroscopic arthrography and magnetic resonance (MR) arthrography are both used for diagnosis. Currently there are no studies comparing the effectiveness of these two modalities.

Tibial stress injury: relationship of radiographic, nuclear medicine bone scanning, MR imaging, and CT Severity grades to clinical severity and time to healing.

Purpose: To examine the relationship between severity grade for radiography, triple-phase technetium 99m nuclear medicine bone scanning, magnetic resonance (MR) imaging, and computed tomography (CT); clinical severity; and recovery time from a tibial stress injury (TSI), as well as to evaluate interassessor grading reliability.

Materials And Methods: This protocol was approved by the Griffith University Human Research Ethics Committee, the Stanford University Panel on Human Subjects in Medical Research, the U.S.

Unexpected decline in tuberculosis cases coincident with economic recession - United States, 2009.

Background: Since 1953, through the cooperation of state and local health departments, the U.S. Centers for Disease Control and Prevention (CDC) has collected information on incident cases of tuberculosis (TB) disease in the United States.

Acetabular labral tears rarely occur in the absence of bony abnormalities.

We evaluated the percentage of patients with acetabular labral tears who have a structural hip abnormality detectable by conventional radiography. Records from our institution from 1996 through 2002 were reviewed to identify all patients with labral tears. Patients were excluded who had classic hip dysplasia, advanced osteoarthritis, or a history of pelvic or femoral osteotomy.
