Plackett-Burman experimental design was used to screen important medium components influencing the production of polyribosyl ribitol phosphate by Haemophilus influenzae type-B under submerged fermentation. Eleven media parameters such as Glutamic acid, Yeast extract, cystein, dextrose, NAD, heamin, NaCl, NH4Cl, Na2HPO4, KCl, and MgSO4.7H2O were screened in twelve experimental runs as per the de...

Biocement can be achieved through the microbially induced carbonate precipitation (MICP) process. Such a method potentially utilized as an eco-friendly for civil and environmental engineering applications such soil ground improvement wind erosion control of surface soil. In this method, one key step is effective production ureolytic bacteria. previous laboratory field studies, cultivation bacte...

1. Heptaminol stopped or delayed the progressive decline in tension which characterizes the phenomenon of fatigue in frog isolated twitch muscle fibre. 2. Heptaminol had no action on the sodium, potassium and calcium voltage-dependent ionic conductances. 3. The hypothesis of an action via an internal alkalinization was tested by comparison with the action of NH4Cl. Both substances increased the...

The smaller subparticle of rabbit reticulocyte ribosomes was shown to yield core-particle and split-protein fractions on treatment with 2.5 M-NH4Cl/61 mM-MgCl2. The core-particle fraction was inactive in poly(U)-directed polyphenylalanine synthesis, but activity was restored after recombination with the split-protein fraction. Optimum ionic conditions for the reconstruction of active subparticl...

The effects of SbI3, PbCl2, and NH4Cl addition to perovskite CH3NH3PbI3 precursor solutions on photovoltaic properties were investigated. TiO2/CH3NH3Pb(Sb)I3(Cl)-based photovoltaic devices were fabricated by a spin-coating technique, and the microstructures of the devices were investigated by X-ray diffraction and scanning electron microscopy. Current density-voltage characteristics and inciden...

Visible-light-responsive tubular N-doped TiO2 nanocrystallites were synthesized via an environment-conscious solvothermal treatment of protonated titanate nanotubes in an NH4Cl/ethanol/water solution.
