Volatile basic nitrogen measurement in digesta using a Berthelot reaction in automated Skalar instrumentation

Nondestructive Determination of the Total Volatile Basic Nitrogen (TVB-N) Content Using hyperspectral Imaging in Japanese Threadfin Bream (Nemipterusjaponicus) Fillet

Background and Objectives: Considering the importance of safety evaluation of fish and seafood from capture to purchase, rapid and nondestructive methods are in urgent need for seafood industry. This study aimed to assess the application of hyperspectral imaging (HSI: 430-1010 nm) for prediction of total volatile basic nitrogen (TVB-N) in Japanese-threadfin bream (Nemipterusjaponicus) fillets, ...

MEASUREMENT OF D2O IN WATER USING 2H(?,n)1H REACTION

Utilization of Photodisintegration reaction of Deuterium, 2H(?,n)1H, is a precise technique for determining the percentage of 2H in tritiated and natural water. The 23Na(n,?)24Na reaction is a suitable ?-source for producing the 2H(?,n)1H reaction. Tehran Research Reactor was used as a neutron source for producing 24Na isotopes. The BF3 detectors were used to detect the neutron emission of H2 c...

Adaptation of the Berthelot Color Reaction for the Determination of Urea Nitrogen in Serum and Urine to an Ultramicro System.

Fluorescence: Basic Instrumentation

originated with Gaviola 1 who termed his lifetime instrument a “fluorometer". Clearly the starting point for any fluorescence observation is the light source. Fortunately, we no longer need to rely on sunlight as the principle excitation source for fluorescence. A comprehensive discussion of the development of light sources is beyond the scope of this chapter, but a good index of a wide range o...

Instrumentation for Laboratory Exercises in Basic Electrophysiology *

The apparatus described below was used during the past year to provide first-year medical and graduate students with an opportunity to observe and study for themselves basic phenomena characteristic of the excitable tissues in general and nerve in particular. The apparatus represents the culmination of numerous attempts on our part to design and develop an arrangement that would be relatively s...
