Natural Flavonoids Interact with Dinitrobenzene System in Aprotic Media: An Electrochemical Probing

Natural Product Communications, 2012
Three structurally related natural flavonoids (FlOH), quercetin (Q), rutin (R) and morin (M), were investigated by cyclic voltammetry to probe their interactions with hazardous 1,4-dinitrobenzene (1,4-DNB) using a glassy carbon electrode. Scavenging of 1,

Invariant Generation through Strategy Iteration in Succinctly Represented Control Flow Graphs [PDF]

Logical Methods in Computer Science, 2012
We consider the problem of computing numerical invariants of programs, for instance bounds on the values of numerical program variables. More specifically, we study the problem of performing static analysis by abstract interpretation using template ...

Phenomenology of GeV-scale scalar portal [PDF]

, 2019
We review and revise the phenomenology of the scalar portal -- a new scalar particle with the mass in GeV range that mixes with the Higgs boson. In particular, we consider production channels $B\to S K_1(1270)$ and $B\to S K_0^*(700)$ and show that their

‘Capiture’ plants with interesting biological activities: a case to go

Open Chemistry, 2017
The investigation of natural products used in Traditional Medicine in Africa is complicated as modern analytical and screening methods are often not available. Computer aided product identification from traditional usage records (CAPITURE) may provide an

Effects of a low-phosphorus diet and exogenous phytase on performance, egg quality, and bacterial colonisation and digestibility of minerals in the digestive tract of laying hens

Czech Journal of Animal Science, 2015
The objective of the experiment was to determine the effects of different levels of phytase (0, 150, 250, and 350 phytase units (FTU)/kg; F) produced by Aspergillus niger in the diets of hens fed decreased contents of non-phytate phosphorus (1.8 and 2.1 ...

The effect of non-phytate phosphorus and phytase levels on performance, egg and tibia quality, and pH of the digestive tract in hens fed higher-calcium-content diet

Czech Journal of Animal Science, 2014
The effect of three levels of non-phytate phosphorus (NPP) (3.0, 2.1, and 1.7 g/kg) and two levels of 3-phytase (F) (0 and 150 phytase units (FTU)/kg) together with a high dietary calcium concentration (approximately 41.0 g/kg) on the performance ...
