THE RELATIONSHIP BETWEEN PEAK PARTICLE VELOCITY AND VIBRATION LEVEL ON BLAST VIBRATION
Doboku Gakkai Ronbunshu, 2000 発破による振動の評価尺度として振動レベルが用いられることが多くなっているが, この場合振動波形が得られない. このため, 加速度を計測して速度に変換し, 振動の最大速度振幅と振動レベルの関係式から振動レベルを推定することが多いが, この場合, 発破方法の違いが関係式に反映されない. そこで本研究では, 重畳シミュレーションにより得られた発破振動の最大速度振幅と振動レベルを用い, 発破施工の観点から発破方法の違いによる最大速度振幅と振動レベルの関係について検討する. その結果, 初段に用いる雷管の種類, 段当り孔数, 発破パターン, 振動の継続時間が関係式のA値に及ぼす影響を明らかにした.

EFFECT OF OPERATING PARAMETERS ON THE MINIMUM FLUIDISATION VELOCITY OF AN INCLINED FLUIDISED BED [PDF]
, 2003 Fluidisation phenomena in an inclined fluidised bed (IFB) systems are poorly understood and receive less attention as compared to that of vertical fluidised bed although in practice there are many fluidised bed systems not vertically oriented.

Studying Peak Particle Velocity Due to Blast in Development Tunnels’ Face in Coal Stoping [PDF]
International Journal of Mining and Geo-Engineering, 2018 The impact of blast-driven shocks on the safety and stability of the underground coal mines has been well established. The seismic imperfections resulting from blasting depend on the total explosive energy released during blasting and the closeness of ...

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

Design and numerical simulation of the real-time particle charge and size analyser [PDF]
, 2012 The electrostatic charge and size distribution of aerosol particles play a very important role in many industrial applications. Due to the complexity and the probabilistic nature of the different charging mechanisms often acting simultaneously, it is ...

FEBS Letters, EarlyView.Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.
