Researchers in Spain have studied the underlying mechanisms of water condensation in the troposphere and found a way to make artificial materials to control water condensation and trigger ice formation at room temperature -- all described in the Journal of Chemical Physics.
How to deal with water condensation on equipment? - posted in Buildings Design & Construction: I work in the salad industry and the current hot point is water condensation on equipment and structures. Does anyone know of an article which addresses this issue that I could include with my SOP? Thank you! Wendy
The main aim of the present study was to quantify the magnitude of differences introduced when estimating a given blood volume compartment (e.g. plasma volume) through the direct determination of another compartment (e.g. red cell volume) by multiplication of venous haematocrit and/or haemoglobin concentration. However, since whole body haematocrit is higher than venous haematocrit such an approach might comprise certain errors. To test this experimentally, four different methods for detecting blood volumes and haemoglobin mass (Hbmass) were compared, namely the carbon monoxide (CO) re-breathing (for Hbmass), the indocyanine green (ICG; for plasma volume [PV]) and the sodium fluorescein (SoF; for red blood cell volume [RBCV]) methods. No difference between ICG and CO re-breathing derived PV could be established when a whole body/venous haematocrit correction factor of 0.91 was applied (p = 0.11, r = 0.43, mean difference -340 ± 612 mL). In contrast, when comparing RBCV derived by the CO ...
A mask fitting system (1) for selecting a mask system for a patient includes at least one terminal (6) which receives data unique to a patient. The patient data can be scanned in using a scanner, such as a handheld or 3-D scanner, or the relevant dimensions of the patient can be simply input into the terminal. A database (2) is provided to store mask system data relating to a plurality of potential mask system solutions for the patient. A communication channel (4) is provided by which the data received by the terminal can be compared with mask system data stored in a mask system database, so as to generate a best-fit mask system result. The best-fit result may include one or more mask system recommendations for the patient.
A disposable re-breathing apparatus for use with hyperventilating patients has a disposable, flexible polymer bag which attaches to a nose/mouth mask and an air control valve located between the mask and the disposable bag which adjusts the ratio of re-breathed air to fresh air through a fresh air inlet. The fresh air inlet has a check valve preventing exhaling air therethrough and a pressure relief valve may be provided to release re-breathed air when the polymer bag becomes filled.

Increased participation of competitive athletes in new methods of simulated altitude warrants research on changes in performances. PURPOSE: To ascertain the effects of intermittent simulated altitude exposure via re-breathing on cycling performance. METHODS: Eighteen, well-trained male cyclists engaged in the use of a re-breathing simulated altitude device for 15 days. Subjects were randomly assigned to 1 of 2 simulated altitude groups; a low constant exposure group (CON) or progressively increased exposure group (TRT). Each exposure consisted of alternating between a rebreathing device and atmospheric air for 6 min and 4 min, respectively over 1 hour. Oxygen saturation was monitored with a pulse oximeter; and either held constant (98% over 15 days; equivalent altitude equal 150 m) or progressively reduced (90% on the 1 ii st day to 77% on the 15th day; equivalent altitudes equal 3600-6300 m). An exercise performance test was performed to familiarize subjects to the protocol (FAM), prior to ...

Superhydrophobic-superhydrophilic patterned surface is widely investigated due to its combination of fast water nucleation and efficient droplet departure, which are important factors to lower interfacial thermal resistance and then enhancing water harvesting efficiency. Preparation methods used nowadays are photolithography, inkjet printing, sol-gel and so on, which either involves complicated and non-scalable procedures or is not able to prepare well-defined patterns. This work demonstrates a facile surface engineering method to prepare superhydrophilic patterns on superhydrophobic substrate which is grown with closely packed TiO2 nanorods. The pattern size can be well controlled by using different masks under UV shinning. With different UV irradiation time, patterns with microscale and nanoscale sizes are able to prepare. The relationship between pattern size and its water harvesting efficiency is studied. Preliminary result shows that the water collection rate of biphilic patterned surface ...
New data from the Copernicus Sentinel-5P satellite reveal the decline of air pollution, specifically nitrogen dioxide concentrations, over Italy. This reduction is particularly visible in northern Italy which coincides with its nationwide lockdown to prevent the spread of the coronavirus.. The animation shows the fluctuation of nitrogen dioxide concentrations across Europe from 1 January 2020 until 11 March 2020. These data are thanks to the Tropomi instrument on board the Copernicus Sentinel-5P satellite which maps a multitude of air pollutants around the globe.. Claus Zehner, ESAs Copernicus Sentinel-5P mission manager, comments, "The decline in nitrogen dioxide concentrations over the Po Valley in northern Italy is particularly evident.. "Although there could be slight variations in the data due to cloud cover and changing weather, we are very confident that the reduction in concentrations that we can see, coincides with the lockdown in Italy causing less traffic and industrial ...
Results: The neuropsychological symptoms score (Q22) revealed that 63.04% of solvents exposed paint manufacturing workers had neuropsychological symptoms, compared to about only 2.1% in control group and the difference was statistically significant. Regarding the relation between types of job done and results of neuropsychological symptoms score (Q22) there was increased risk for neuropsychological symptoms in production group than packing group (OR = 13.94) and for the duration of work the risk increased in workers with duration over 15 years (OR = 32.84). Logistic regression analysis showed that the most important predictors of neuropsychological symptoms were the type of job performed by the workers such as production or packing and their duration of work ≥15 years ...

The most common application of this instrument is to maneuver the ET tube in nasal intubations. The Magill forceps is used to pick up the ET tube in the posterior oropharynx and place its tip into the laryngeal inlet. The forceps grip surface is serrated and care must be taken not to rupture the cuff when maneuvering the ET tube. Ideally the endotracheal tube should therefore be held with the forceps just proximal to the cuff. For the same reason only airway equipment and not tissue should be maneuvered with the forceps as significant trauma and bleeding can result.. The Magill forceps can also be useful in clearing foreign bodies from the upper airway in anesthetized or unconscious patients.. Another use of the device is in placing and removing throat packs.. ...

0058] In fat-metabolism, the decarboxylation of acetoacetate generates acetone, which is one of the most abundant endogenous compounds in human breath. An amount of acetone in healthy subjects is in a range of about 0.2-10 ppm, and acetone is higher in patients having uncontrolled diabetes. The tests were performed by collecting samples from three different human individuals at two different times of a day. Two breath samples were collected from each human individual through a mouthpiece containing a bacteria filter (Vacuumed MQ303) connected directly to the gas line. The PID sensor was pre-heated to 79° C. to prevent water condensation from human breath. One sample was collected about 1 hour before lunch and another sample was collected about 1 hour after lunch. FIG. 12 and Table 1 show the sensor response pattern (output voltage) for the breath acetone as detected by the PID. Comparing the signals obtained before (FIG. 12) and after (data not shown) lunch, as shown in Table 1, the breath ...
It was 1996 when I saw chemtrails being sprayed across the sky for the first time. I was visiting relatives in Kenai, Alaska and we were out camping for the weekend. At first I didnt pay any attention as Ive seen jet contrails overhead ever since I was a youngster. Some 20 minutes later I was considerably more interested as the thin streamers had gradually spread out across the sky in a kind of grid work or tic-tac-toe pattern. We watched in disbelief as a bright clear summer day was turned into a grey overcast soup right before our very eyes. The following afternoon the same thing happened, in pretty much the same way, except this time we got huge X patterns all over the sky. This time the people I was with were just as perplexed as I was, and we began brainstorming to come up with a logical explanation. The very first thing we ruled out was commercial airliner traffic because actual jet contrails are made of water condensation vapor and always dissipate away into nothing before you loose ...

Elimination of heavy solids such as grit from sewage streams prior to introduction into treatment tanks is necessary because such solids interfere with normal operations. Substantially all of the heavy solids, irrespective of particle size are removed by a process and apparatus wherein raw sewage is introduced into a tank, the preferred form of which has a bottom sloping downwardly from the far side to a trough adjacent a first side wall, with even distribution along said first side wall, a predetermined small range of liquid level variation is maintained by flowing effluent sewage over a weir extending above the full length of the top of the side wall opposite said first side wall, air is introduced with even distribution adjacent to said trough and along said first side wall to induce circulatory flow of liquid and light weight solids upwardly and then in the direction of said opposite side wall, turning the circulatory flow direction downwardly toward the tank floor by a baffle spaced from said

That, of course, describes the natural process of the breath, in which the conscious mind, with its slurry of desire, emotion and expectation, is not factored in. But what happens when we overbreathe? Usually an excess of carbon dioxide in the blood tells us to take another breath in, and the process is quite relaxed. But when carbon dioxide drops below a certain level (due to anticipatory fast hard breathing), the message from the body - which is now not receiving the oxygen it needs - is that we are suffocating! And so the breath is driven by the bodys panic, and we breathe harder, making the situation worse instead of better. A subtle chemical imbalance soon becomes a full-blown panic attack. The age-old cure for panic attacks - to breathe into a paper bag - has a very good biochemical basis: its meant to increase the levels of carbon dioxide by re-breathing the same air, until the proper balance is restored ...

Thousands of Oximeter tests have demonstrated that the amount of oxygen in the bloodstream can be increased in less than a minute after OxySorb™ is taken.. A small amount of OxySorb™ helps the lungs to get rid of a large amount of waste gases. Its action is easy to understand, when you realise that theres only a certain amount of haemoglobin (the type of cells which transport gases) in the body. These cells load up with oxygen (and the other gases that youve just breathed in) as they pass through the lungs. On their trip through the body, they drop off oxygen and pick up more waste gases that are typically but not exclusively carbon monoxide (CO) and carbon dioxide (CO2). When they get back to the lungs, the waste gases must be exhaled, so the haemoglobin can be loaded with more oxygen (and the cycle can start over).. OxySorb™ is extracted from Norwegian seaweed, which has to produce oxygen from CO2 in low temperature and virtual darkness. (Thats a much more difficult task than plants ...
A non-rebreathing face mask has an oxygen reservoir bag and one-way valve system which prevents exhaled gases mixing with fresh gas flow. The non-rebreathing mask system may also have a valve on the side ports of the mask which prevents entrainment of room air into the mask. These masks are not commonly used but a non-rebreathing mask can provide higher concentration of FiO2 (> 60%) than is able to be provided with a standard face mask (which is approximately 40% - 50 ...
A four-pass carbon canister includes a cover sealingly coupled to an injection-molded housing having a first chamber, a second chamber fluidly coupled to the first chamber, a baffle fluidly coupled to the second chamber, and a third chamber fluidly coupled to the baffle. The three chambers are filled with carbon pellets to absorb carbon pellets provided to the carbon canister from the fuel tank. The carbon canister is periodically purged by drawing fresh air into the carbon canister, with the fresh air desorbing the hydrocarbons and then provided to and consumed in an internal combustion engine.
