  • pH Tech Tips (.pdf)

    The Concentration ratio of hydrogen ions (H+) and hydroxyl ions (OH-) determine the pH value of a solution. Any hydrogen activity will produce a 59.16 mV/ pH unit across the glass membrane. The measurement is expressed on a scale of 0.0 to 14.0. Water with a pH of 7 is considered neutral (H+ ions

  • Re: PA Mixer/Amp PCB Schematic

    My son is constantly tearing down and repairing mixers, amps, and whatever. He hardly ever replaces entire boards but sometimes it is necessary. No reason you can't just replace the capacitors if you can identify them. If not try searching online for places that sell the schematics. perhaps thi...

    Here you go. Miller 3 ph converter design. All you need to know about making a good reliable and stable phase converter of your own. I am the same guy there as here so I know the design works well!

  • Re: Converting 3 Phase to 1 Phase in Reverse?

    Thanks for the PM you sent me. I will try and work up some better details as I have time. Fist thingiI would suggest is looking fore schematics for 9 lead and 12 lead dual voltage three phase motors then read up on what a zig zag or 'Z" connection is regarding getting single phase form three phase.

  • A red tide alga grown under ocean acidification upregulates its tolerance to lower pH by increasing its photophysiological functions

    A red tide alga grown under ocean acidification upregulates its tolerance to lower pH by increasing its photophysiological functionsBiogeosciences, 11, 4829-4837, 2014Author(s): S. Chen, J. Beardall, and K. GaoPhaeocystis globosa, a red tide alga, often forms blooms in or adjacent to coastal waters and experiences changes in pH and seawater carbonate chemistry caused by either diel/periodic fluctuation in biological activity, human activity or, in the longer term, ocean acidification due to atmospheric CO2 rise. We examined the photosynthetic physiology of this species while growing it under different pH levels induced by CO2 enrichment and investigated its acclimation to carbonate chemistry changes under different light levels. Short-term exposure to reduced pHnbs (7.70) decreased the alga''s photosynthesis and light use efficiency. However, acclimation to the reduced pH level for 1-19 generations led to recovered photosynthetic activity, being equivalent to that of cells grown under pH 8.07 (control), though such acclimation required a different time span (number of generations) under different light regimes. The low-pH-grown cells increased their contents of chlorophyll and carotenoids with prolonged acclimation to the acidification, with increased photosynthetic quantum yield and decreased non-photochemical quenching. The specific growth rate of the low-pH-grown cells also increased to emulate that grown under the ambient pH level. This study clearly shows that \textit{Phaeocystis globosa} is able to acclimate to seawater acidification by increasing its energy capture and decreasing its non-photochemical energy loss.

  • Good news for young patients with a leukemia subtype associated with a poor prognosis

    Adjusting treatment based on early response to chemotherapy made a life-saving difference to young patients with an acute lymphoblastic leukemia (ALL) subtype associated with a poor outcome, researchers have found. The results are good news for children and adolescents with Philadelphia chromosome-like ALL (Ph-like ALL), a subtype that until now was associated with a poor prognosis. Ph-like ALL accounts for as much as 15 percent of the most common pediatric cancer.

  • 0-25mA & 0-100mV Simulator Diagram 24VDC Supply

    Urgent, I need to build a schematic diagram having a 0-25mA & 0-100mV output for calibration(sourcing). The problem is we are required to use 10k potentiometer. We will probably use a selector switch for the 2 options(0-25 & 0-100). You can add other electronic parts in the diagram. Thanks
