This paper presents a wireless system to send biosignals outside a hyperbaric chamber avoiding wires going through the chamber walls. Hyperbaric chambers are becoming more and more common due to new indications of hyperbaric oxygen treatments. Metallic walls physically isolate patients inside the chamber, where getting a patient's vital signs turns into a painstaking task. The paper proposes using a ZigBee-based network to wirelessly transmit the patient's biosignals to the outside of the chamber. In partic...
Implantable cardioverter defibrillators (ICDs) are an effective primary prevention of sudden cardiac death. We examined whether dual-chamber (DC) ICDs confer a greater benefit than single-chamber (SC) ICDs, and compared the long-term outcomes of recipients of each type of device implanted for primary prevention.
A short report describing the unique experience of visiting the famous Brooke Army Medical Center (BAMC) in San Antonio, Texas, USA and its Burn Center and Plastic Surgery Department in the period between June 27 and August 26, 2016.
Nitrate-nitrogen (nitrate-N) removal rates can be increased substantially in denitrifying bioreactors with a corn ( L.) cob bed medium compared with woodchips; however, additional organic carbon (C) is released into the effluent. This laboratory column experiment was conducted to test the performance of a postbed chamber of inert plastic biofilm carrier (PBC) after corn cobs (CC) to extend the area of biofilm colonization, enhance nitrate-N removal, lower total organic C losses, and reduce nitrous oxide (NO...
To compare endothelial cell (EC) variation after anterior chamber phakic intraocular lens (AC-pIOL) implantation in highly myopic patients with a preoperative anterior chamber depth (ACD) between 2.8 and 3.0 versus ≥3.0 mm.
We examined the effectiveness and adverse events of using balanced salt solution (BSS) PLUS containing 0.025% povidone-iodine, a non-oculotoxic concentration, for capsular bag irrigation in a case of endophthalmitis mainly involving the anterior chamber. A 57-year-old female underwent cataract surgery and developed hypopyon on day 3 after surgery, with mainly anterior chamber inflammation. The capsular bag was irrigated with BSS PLUS containing 0.025% povidone-iodine. Gram-negative rods were detected from t...
In this paper, we propose the use of a pixelated transmission chamber, placed between the patient and the imaging detector, to measure the scatter component of a radiation beam impinging on said imaging detector. Using Monte Carlo simulation, a three-parameter model for the propagation of the scatter component in the transmitted beam is first developed. The use of the transmission chamber to determine the model parameters is then modeled, again using Monte Carlo simulation, and the feasibility of this appro...
The article presents the advantages of the radon chamber with volume of 17 m3, that belongs to Silesian Centre for Environmental Radioactivity and its applicability for calibration of equipment designed to measure the radon concentration and its short-lived decay products. The chamber can be operated under controlled conditions in the range from -20 to 60°C and relative humidity from 20 to 90%. There is also discussed the influence of aerosol concentration and their size distribution on the calibration res...
The aim of this study was to examine the effect of sub-millimeter air gaps that may exist between an ionization chamber and solid phantoms when measurements are performed in a magnetic field.
To validate the effects of the new plateau hyperbaric chamber on alleviating high altitude hypoxia on Mount Kun Lun.
Conditions in which exhaled and dermally-emitted bioeffluents could be sampled separately or together (whole-body emission) were created. Five lightly-dressed males exhaled the air through a mask to another, identical chamber or without a mask to the chamber in which they were sitting; the outdoor air supply rate was the same in both chambers. The carbon dioxide concentration in the chamber with exhaled air was 2,000 ppm. Chamber temperatures were 23°C or 28°C and ozone was present or absent in the supply...
Contaminated sediment can release hydrophobic organic contaminants (HOCs) and thereby act as a secondary source of primarily legacy hazardous substances to the water column. There is therefore a need for assessments of the release of HOCs from contaminated sediment for prioritization of management actions. In situ assessment of HOC sediment-to-water flux is currently done with (closed) benthic flux chambers, which have a sampling time exceeding one month. During this time, the water inside the chamber is de...
The aim of this study was to investigate changes in the anterior segment of the eye after cycloplegia. A biometer combined with swept-source optical coherence tomography (SSOCT) was used for measurements. Patients with strabismus or amblyopia who underwent cycloplegia were included. The axial length, central corneal thickness, anterior chamber depth, and lens thickness were measured with the biometer-SSOCT system before and after cycloplegia. Altogether, 10 eyes of 10 patients (mean age 7.20 ± 3.08 years, ...
