by electroless or vacuum deposition,the stripped substrate being contacted with a solution of an organic silane before or during application of the permanent coating. The oxidized foil may be stripped with HCl or NaOH, the substrate being then washed in H 3 PO 4 , sensitized with Pd-SnCl 2...
Subsequently, 500 µL of HCl (6 M) was added, and the aforementioned homogenization, ultrasound-assisted agitation, and cooling steps were repeated. pH was measured to ensure a value less than or equal to 3, and then, 400 µL of AcOEt were added, stirred in a vortex mixer for 30 ...
Alkalinity of the seawater was measured by titration with HCl (Jenkins et al., 1981). The soluble components were characterized after filtration of sample through 0.45 μm filter (PP membranes). In order to measure the elemental composition of the precipitates, the samples were dissolved in 1 ...

MATERIALS AND METHODS Analysis of SILOhealth 104 The SILOhealth 104 product was first emulsified in water (18.21 mg/mL) with the addition of NaOH (120 mM) to bring the pH to 8.5, then hydrolyzed with HCl/MeOH at 22°C for one hour. After total hydrolysis, one aliquot of the sample ...
The results showed that apparent digestibility coefficient (ADC) of protein significantly increased in T3–T5, while ADC of lipid and total amino acid absorption rate increased in T2–T5 as compared to control (T1). Among the essential amino acids (EAA), arginine exhibited maximum absorption ...
