Rapid Determination of Lead in Barium-bearing Ores by EDTA Compleximetry
Yankuang ceshi, 2013 For the determination of lead content in barium-bearing samples by the EDTA volumetric method, the lead analysis result is low due to the presence of lead sulfate and barium sulfate double salt formed during the analysis process.

Flow injection determination of readily assimilable nitrogen compounds during vinification [PDF]
, 2002 A flow injection method for the determination of readily assimilable nitrogen (r.a.n.), i.e. ammonium and aminated nitrogen, is reported. The difference in pH of the sample in the presence and absence of formaldehyde, which blocks the amino function ...

Multi‐Targeting Non‐Specific Genome Engineering in Bacteria
Advanced Science, EarlyView.In this study, we provide the first case to use the multi‐targeting integrase (MTI) systems in bacteria and develop a host‐independent generalizable approach, MNGE (Multi‐targeting Non‐specific Genome Engineering), for multi‐copy and random integration of metabolic genes or pathways in both Gram‐positive and Gram‐negative bacteria, which will ...

On the unlikelihood of specific long range forces in immunologic and enzymatic reactions [PDF]
, 1950 In the past few years, a great many experiments have been performed by Rothen (24, 25) which he has interpreted as suggesting that antigen and antibody, and enzyme and substrate proteins, can react specifically, although separated by distances of ...

Bronchial Circulation Angiogenesis in the Rat Quantified with SPECT and Micro-CT [PDF]
, 2008 Introduction As pulmonary artery obstruction results in proliferation of the bronchial circulation in a variety of species, we investigated this angiogenic response using single photon emission computed tomography (SPECT) and micro-CT.

Advanced Science, EarlyView.Bimodal modulation of nitric oxide in endothelial cells is achieved by light‐sensitive polymer nanoparticles. In dark, P3HT/PEDOT:PSS NPs boost intracellular ·NO, upregulate both endothelial and induced nitric oxide synthase, and drive a metabolic shift toward glycolysis.
