  • Publication number: 20240113660
    Abstract: A self-biased, closed loop, low current free running oscillator clock generator method and apparatus are provided with a current mode comparator connected to a trimming resistor and configured to compare an internally generated voltage reference VREF signal to a voltage feedback signal VFB, where the current mode comparator comprises a common gate amplifier connected to a current mirror circuit in a negative self-biased closed loop to generate a control current signal for controlling a current controlled oscillator to produce an output clock signal having a clock frequency based on the control current signal, where a frequency-to-voltage converter is connected in a feedback path to receive the output clock signal and is configured to produce the voltage feedback signal VFB for input to the current mode comparator, wherein the clock frequency of the output clock signal is tuned to a nominal locked output frequency fOUT by the trimming resistor.

  • Patent number: 11925622
    Abstract: The present intervention identifies the antiglycating inhibitors from a series of carbazole-linked 1,2,3 triazole derivatives through in vitro MGO-mediated glycating BSA model. Derivatives 12, and 13 established a remarkable antiglycation activity at the receptor level in human monocytes. These compounds were found non-toxic, and possess the potential to halt AGE-RAGE/ROS-mediated NF-kB-dependent COX-2, and its proinflammatory product, PGE2, production in monocytes. Hence, carbazole-linked 1,2,3 triazole derivatives provide treatment modalities to delay or prevent the onset of late diabetic micro- and macro-vascular complications in diabetic patients.

  • Patent number: 10301218
    Abstract: The low cement content strain-hardening cementitious composite is cement with a natural pozzolan replacing a significant portion of the Portland cement therein. The strain-hardening cementitious composite includes a mixture of cement, fly ash, sand, a polycarboxylic ether-based superplasticizer, and reinforcing polyvinyl alcohol fibers. The mixture is formed with a low content of Portland cement (6-12 wt %) and with ground scoria as the natural pozzolan (5-20%). The sand forms at least 22 wt % of the strain-hardening cementitious composite and is preferably in the form of sieved dune sand, having a silicon dioxide concentration of between approximately 80 and 90 wt %, and a feldspar concentration of between approximately 10 and 20 wt %. The dune sand is sieved such that the sand grains have a median diameter of less than or equal to approximately 300 ?m, and preferably have a median diameter of approximately 200 ?m.

  • Patent number: 9623451
    Abstract: The EAFD stabilizer for returned concrete and mixer drum wash water includes various methods of using EAFD as a stabilizer in making concrete. The potentially hazardous stockpile of EAFD can be used in practical construction, which has a positive impact on the environment. A certain amount of EAFD is added to cement being mixed or to wash water and acts as a stabilizer, the wash water being used to make a cement mixture. This resultant EAFD stabilized concrete mixture stabilizes overnight.

  • Patent number: 9423326
    Abstract: The method of obtaining simulated pore water includes: mixing cement with a quantity of water and waiting a period of time for water-soluble salts in the cement to dissolve; filtering the mixture; evaporating an aliquot of the filtrate; weighing solids obtained by evaporating the aliquot to determine total dissolved solids or salts in the aliquot; weighing the remaining filtrate and measuring its volume; determining the mass of total dissolved solids in the remaining filtrate; determining the mass of water in remaining filtrate; determining the mass of water that would be in the remaining filtrate if the mix had been prepared with a desired W/C ratio; evaporating any difference between the mass of the remaining filtrate and the mass that would be present at the desired W/C; and collecting the filtrate remaining as simulated pore water for the desired W/C ratio which may be used for a variety of different applications.
