Pengaruh Variasi Agregat Kasar Penyusun Beton Terhadap Kerapatan Beton Dengan Menggunakan Transmission Time Pada Alat UPV (Ultrasonic Pulse Velocity)

open access: yesRekayasa Sipil, 2019
To find out the quality of concrete, we need to test the concrete. Which is non destructive test or testing without damaging the test object, namely with an UPV (Ultrasonic Pulse Velocity). In this study using 4 variations of coarse aggregate composition

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

open access: yesFEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

High fidelity femtosecond pulses from an ultrafast fiber laser system via adaptive amplitude and phase pre-shaping [PDF]

open access: yes, 2009
We report the generation of a 12.6W average power, 50MHz repetition rate pulse train, compressible to high fidelity 170fs pulses, from an ultrafast ytterbium-doped fiber laser system via adaptive amplitude and phase pre ...

Amplitude Control of Single Phase Capacitor Motor [PDF]

open access: yesKirkuk Journal of Science, 2010
The method is proposed to study the performance of single-phase capacitor motor with amplitude control. This is clearly shown by controlling the speed of the motor with varying the applied voltage to the control voltage while the excitation voltage is ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Iterative amplitude/phase multiple-symbol differential sphere detection for DAPSK modulated transmissions

open access: yes, 2012
Differentially encoded and non-coherently detected transceivers exhibit a low complexity, since they dispense with complex channel estimation. Albeit this is achieved at the cost of requiring an increased transmit power, they are particularly beneficial,

Artificial molecular machines and motors—Design and control of nanoscale motion

open access: yesFEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...
