Air-Filtration unit from a German bunker WWII
Many German bunkers from WWII had these anti-gas air filtration systems installed that had to manually be operated to pump outside air through an air filter in to the bunker. The round pressure-valves in the walls can be found in most bunkers. These are called "uberdruckventil" and that basically means over-pressure-valve and would automatically let air out in case of overpressure inside the bunker. Source: Objaverse 1.0 / Sketchfab

Results of core filtration tests to assess the reduction in permeability due to colloid migration
<p>Results of filtration tests of three core samples, filtered liquid - deionized water and kerosene. Filtration installation - AFS-300. Filtering conditions inside files. Core samples are registered in IGSN, the numbers and type of fluid are indicated in the file name. Prior to filtration, the samples are saturated under vacuum for 24 hours.

Improved biodiversity detection using a large-volume environmental DNA sampler with in situ filtration and implications for marine eDNA sampling strategies
<p>Metabarcoding analysis of environmental DNA samples is a promising new tool for marine biodiversity and conservation. Typically, seawater samples are obtained using Niskin bottles and filtered to collect eDNA. However, standard sample volumes are small relative to the scale of the environment, conventional collection strategies are limited, and the filtration process is time consuming. To overcome these limitations, we developed a new large – volume eDNA sampler with in situ filtration, capable of taking up to 12 samples per deployment. We conducted three deployments of our sampler on the robotic vehicle <em>Mesobot</em> in the Flower Garden Banks National Marine Sanctuary in the northwestern Gulf of Mexico and collected samples from 20 to 400 m depth. We compared the large volume (~40 – 60 liters) samples collected by <em>Mesobot</em> with small volume (~2 liters) samples collected using the conventional CTD rosette – mounted Niskin bottle approach. We sequenced the V9 region of 18S rRNA, which detects a broad range of invertebrate taxa, and found that while both methods detected biodiversity changes associated with depth, our large volume samples detected approximately 66% more taxa than the CTD small volume samples. We found that the fraction of the eDNA signal originating from metazoans relative to the total eDNA signal decreased with sampling depth, indicating that larger volume samples may be especially important for detecting metazoans in mesopelagic and deep ocean environments. We also noted substantial variability in biological replicates from both the large volume <em>Mesobot</em> and small volume CTD sample sets. Both of the sample sets also identified taxa that the other did not – although the number of unique taxa associated with the <em>Mesobot</em> samples was almost four times larger than those from the CTD samples. Large volume eDNA sampling with in situ filtration, particularly when coupled with robotic platforms, has great potential for marine biodiversity surveys, and we discuss practical methodological and sampling considerations for future applications.</p>
Degradation of pharmaceuticals using the hybrid ozonation-filtration system
<p>The hybrid ozonation-membrane filtration unit allows the simultaneous treatment of the contaminated water with ozone and micro- and nano-filtration (MF/NF) under controlled conditions using commercial single tubular ceramic membranes with an inside-out operation. In total, four commercial ceramic (CM) membranes with different compositions and pore sizes were selected. The composition of the selected membranes is given below</p> <ul> <li>TiO<sub>2</sub>/ZrO<sub>2</sub> composition of three different pore sizes: 50-, 150-, and 300 kDa MWCO) and</li> <li>TiO<sub>2</sub>/ TiO<sub>2</sub>+ZrO<sub>2</sub> composition of one pore size (0.200 μm MWCO).</li> </ul> <p>The files contain information on the degradation of the pharmaceuticals using the different membranes under the three surface modifications; CeO2, CeTiOx and CeO2+CeTiOx.</p> <p>Permeability tests have been performed on all four membranes. The filtration unit can operate from 0.3 -1.5 bar pressure with a permeability flow ranging from 200 - 1900 L.m<sup>-2</sup>.h<sup>-1</sup> at 1 bar, starting from the lowest molecular weight cut-off (MWCO) membrane (50 kDa) and moving to the higher (0,200 μm) one.</p>

Filtration
<p>A significant part of us are lucky enough to approach a wellspring of by and large clean water. Regardless, in light of the fact that our water is seen as proper for usage by your city, doesn't mean it's ideal enough to verify your home or your wellbeing. In reality, water filtration is central for remaining in charge of what engineered mixes can navigate from your water into your home.So it is fundamental to fit a <a href="http://http://aquaguarduae.com/">Water filter</a> in anywhere.The Eureka forbes dubai give standard quality water filters,<a href="http://https://aquaguarduae.com/products/water-softners/">water softener</a> and so on which are basic for people.</p>
Dataset for: How eDNA data filtration, sequence coverage, and primer selection influence assessment of fish communities in northern temperate lakes
<p><span>For nearly 15 years now, environmental DNA</span><span> has demonstrated</span><span> its effectiveness in monitoring biodiversity. Methodological and technical improvements have significantly enhanced the field. However, the effect of factors such as sequence coverage, bioinformatic filtration and primer choice have been less explored or need to be optimized according </span><span>to </span><span>specific survey objectives and </span><span>study </span><span>site characteristics. We evaluated these factors </span><span>to </span><span>help optimize monitoring fish biodiversity in North American temperate lakes. We sampled water for fish community eDNA analysis in 12 lakes from southwestern Québec, Canada. The lakes were selected to encompass a wide range of surface areas and species richness. We sampled water from a total of </span><span>520</span><span> sites (25 to 50 per lake) and analyzed three mitochondrial DNA regions (12S rRNA; 16S rRNA; and cytb) using NovaSeq</span><span> sequencing. Our results, based on rarefied count matrices (from a sequencing depth of 100,000 to a minimum </span><span>depth </span><span>of 1,000 reads per sample), </span><span>showed</span><span> that </span><span>keeping only</span><span> species </span><span>in each sample if they</span><span> represented </span><span>at least one thousandth (species </span><span>minimum </span><span>read proportion threshold =</span><span> 0.001</span><span>)</span><span> of the </span><span>sample's</span><span> reads was adequate to remove false positives </span><span>and had a limited negative</span><span> impact on true positives</span><span> with low read counts. The</span><span> sequencing depth </span><span>was found to have</span><span> a negligible impact </span><span>on the accuracy</span><span> of fish </span><span>community assessment in a given lake. With the same sequencing depth and a complete local reference database for each primer set, </span><span>a single primer set </span><span>produced</span><span> similar species richness medians than the combination of two or three primer sets. Overall, 12S and 16S detected more species and provided more consistent community profiles than cytb. </span><span>Based on our observations, we suggest using the 12S MiFish-U primer set and applying a minimum proportion of 0.001 reads per species and site to monitor north-temperate lentic freshwater fish communities.</span></p>
