Location of Yamagawa Beach (a), transect across HS6 (b), and sampling sites in the Yamagawa coastal hydrothermal field (c). Sampling sites are shown in italic. See text for abbreviations. Numbers in parentheses indicate the temperature of the samples. *Reference site is off the transect, approximately 10 m from HS6.
Gas samples were collected from the bottom layer of each point (a sample was additionally collected from the surface layer of HS6) using a 50 mL syringe equipped with a 30 cm length needle. Gas contents were analyzed using gas chromatography (GC-2014; Shimadzu, Kyoto, Japan) equipped with a thermal conductivity detector and a SHINCARBON ST packed column (Shinwa Chemical Industries, Kyoto, Japan). Argon was used as the carrier gas.

In archaeal communities, the most striking difference between HSB and other samples was the predominance of hyperthermophilic Crenarchaeota (Desulfurococcaceae, Pyrodictiaceae, and Thermoproteaceae) at HSB (Fig. 5). Sequences assigned to the family Desulfurococcaceae were closely related to the genus Aeropyrum (Table S1). In addition to the detection of relative clone sequences, the isolation of strains affiliated in this genus (Tanaka et al. unpublished data) and two novel strains of virus infecting the members of this genus (38, 39) ensured the inhabitation of this hyperthermophilic archaeon in this environment. The genus Aeropyrum consists of two species, A. pernix and A. camini, originally isolated from a shallow hydrothermal vent (53) and from a deep-sea hydrothermal vent (42), respectively. Both species are strictly aerobic heterotrophic hyperthermophiles. Clones assigned to the family Pyrodictiaceae were most closely related to Geogemma indica strain 296T or clone sequences obtained from deep-sea hydrothermal vents (Table S1). The family Pyrodictiaceae consists of anaerobic hyperthermophiles optimally grow at temperatures above 100C, such as the genera Pyrodictium (45, 58), Geogemma (22), Hyperthermus (70, 71), and Pyrolobus (5). The sequences assigned to the family Thermoproteaceae were related to the genus Pyrobaculum and most closely related to an isolate from Obama Hot Spring (Table S1), which is a coastal hot spring located approximately 180 km north of the Yamagawa coastal hydrothermal field. The members of the genus Pyrobaculum are hyperthermophilic facultative anaerobes. The members of the family Pyrodictiaceae and the genus Pyrobaculum grow heterotrophically or chemolithoautotrophically using molecular H2 as an electron donor.
Overall, the bacterial community of the Yamagawa coastal hydrothermal field consists of diverse taxa, including both thermophiles and mesophiles. The only bacterial order shared by all samples was Rhodobacterales of the phylum Alphaproteobacteria (Fig. 7, Table S2). The order is phenotypically, metabolically, and ecologically diverse (18). However, many of them are aquatic and require NaCl for growth. Including Rhodobacterales, most bacterial clones were relative to clone sequences retrieved from marine environments around the world.
Blood plasma separation is a prerequisite in numerous biomedical assays involving low abundance plasma-borne biomarkers and thus is the fundamental step before many bioanalytical steps. High-capacity refrigerated centrifuges, which have the advantage of handling large volumes of blood samples, are widely utilized, but they are bulky, non-transportable, and prohibitively expensive for low-resource settings, with prices starting at $1,500. On the other hand, there are low-cost commercial and open-source micro-centrifuges available, but they are incapable of handling typical clinical amounts of blood samples (2-10mL). There is currently no low-cost CE marked centrifuge that can process large volumes of clinical blood samples on the market. As a solution, we customised the rotor of a commercially available low-cost micro-centrifuge (~$125) using 3D printing to enable centrifugation of large clinical blood samples in resource poor-settings. Our custom adaptor ($15) can hold two 9 mL S-Monovette tubes and achieve the same separation performance (yield, cell count, hemolysis, albumin levels) as the control benchtop refrigerated centrifuge, and even outperformed the control in platelet separation by at least four times. This low-cost open-source centrifugation system capable of processing clinical blood tubes could be valuable to low-resource settings where centrifugation is required immediately after blood withdrawal for further testing.

RBCs and platelets count, hematocrit (Hct), and hemoglobin (Hgb) of all the pre-and post-centrifuged blood and plasma samples were measured by a hematology analyzer (Sysmex XP-300, Sysmex Corporation, Japan). These measurements were used to compare the separation efficiency and purity of different designs.
After achieving a higher speed (4160 RPM) with the original truncated cone shape design C, speed was further increased with the later designs D-E by decreasing the lateral surface area (Fig 4C). Design with a smaller lateral surface area provided the least air resistance during the rotation which increased the speed of these designs. The final design E5, achieved a rotational speed of 6884 RPM, almost the rated speed of the original mini-centrifuge, and a RCF value of around 1100g. The final RPM is higher than that of many previously designed centrifuges [16, 18, 19, 21, 42] which was critical in achieving our operational requirement R8. Despite the fact that some of the previously developed devices have similar [20] or higher [17] RPM, our design stands apart for severa reasons. Firstly, none of the high-speed devices can handle samples with large volumes (>9 mL). Secondly, because our design can directly accommodate this widely used Monovette blood handling tubes, there is no need to process the blood after withdrawal. Our design is simple, consisting of three parts: a tube holder, as well as a base and lid that can be threaded with the tube holder. It can be noted that the final three designs (E0, E2 and E5) all possess a 25 rotational angle. Although a higher angle is recommended to ensure the most compact pellet, the trade-off has to be made to increase the speed and RCF of the designs. The evaluation of all designs against the set list of requirements is available as (S5 Table in S1 File).
Firstly, the total RBC count was measured each time the blood sample was remixed following centrifugation to investigate the integrity of the blood sample after centrifugation. Fig 7A presents the pre-and post-centrifuged whole blood RBC count at 3, 6 and 10 minutes. It is apparent that there was no significant decrease in RBC count between centrifugations. Due to the removal of plasma (the hematology analyser removes around 50 L of the sample during each measurement) at every time instance, we noticed a slight increment in the RBC count per litre of blood on some of the designs (and control). The absence of hemolysis in most of the samples (see Section 3.6) corroborate this interpretation.
Albumin is known to be the most abundant plasma protein in humans which accounts for almost 60% of the total serum protein. It is an established biomarker of nutritional status [51] and reliable prognostic indicator for heart failure [52], pulmonary arterial hypertension [53], in acute surgical patients [54], morbidity and mortality [55] and many more diseases. The recovered plasma from the best designs (E0, and E2) and control centrifugation (single and double) were analysed to quantify the concentration of albumin. The albumin quantification from the sample was obtained by directly measuring the absorbance at 610 nm when the available albumin in a sample provides a peak in the presence of reagent bromocresol purple (see Materials and Methods). As shown in Fig 8B, E0 and E2 samples (single and double centrifugation) showed a similar concentration to the full-scale centrifuge control, around 1.5 mM (~2.5 g/dL) with no statistically significant difference which shows the adapted centrifuge is suitable for plasma protein studies. Similar albumin level has been detected in previous studies [49]. The albumin concentration in all samples, including control samples, was slightly lower than the normal range of Albumin in plasma (3.4 to 5.4 g/dL), which can be explained by the age of the samples (3 days old).
"Unfinished Sympathy" is a song by the English trip hop group Massive Attack. It was released on 11 February 1991 under the temporary group name Massive.[1] The song was written by the three band members Robert "3D" Del Naja, Andrew "Mushroom" Vowles and Grant "Daddy G" Marshall, the song's vocalist Shara Nelson and the group's co-producer Jonathan "Jonny Dollar" Sharp. It was released on 11 February 1991 as the second single from the band's first album, Blue Lines (1991), on the band's Wild Bunch label distributed by Circa Records.[2] The name "Massive" was used to avoid a radio ban, as the track's release coincided with the Gulf War. Produced by Massive Attack and Dollar, the song incorporates various musical elements into its arrangement, including vocal and percussion samples, drum programming and string orchestration by the arranger Wil Malone.
"Unfinished Sympathy" received acclaim. Jim Arundel from Melody Maker wrote, "It'll be the "When a Man Loves a Woman" of its time, mark me well."[11] Barbara Ellen from NME named it Single of the Week and called it "an intense, warmblooded dance track that boasts more fire in its balls than the Pixies ever dug for", a reference to the Pixies' recently released single "Dig for Fire".[12] Another editor, Mandi James, expanded, "Lush and extravagant, plied with rich strings and roving keyboards, this is music with depth and grace. Massive aren't afraid to indulge their imaginations and let themselves go. Plaintive vocals that smack of Randy Crawford, smart samples liberated from the Mahavishnu Orchestra and all the romanticism of the Pet Shop Boys without the clipped, camp edge. Those not completely smitten by this record have no soul."[13] Record Mirror also named it single of the week and wrote, "The wisely understated production allows both the beauty of the swelling strings and the emotional pull of the vocals to shine through. Fiendishly expert with rhythms, too cerebral to be termed just a dance act, Massive can't put a foot wrong."[14] Melody Maker named "Unfinished Sympathy" its Single of the Year, writing that it would "unquestionably stand as one of the greatest soul records of all time".[15] NME named it the year's eighth-best single.[16] be457b7860
