if the luminaire is so designed that no voltage breakdown is expected to occur when the bil voltages of table 1 are applied to the luminaire, then the test method of section 6.1 shall be used. if the luminaire is designed with small electrical gaps or other types of surge protection ...
(2) The scatter fractionSF, which is defined in the mentioned section 4.4.5, in turn includes the scattered count rate SF=RsRt+Rs (3) These three equations are not satisfiable forRint>0 as shown in the following proof. We insert the definition ofSF(i.e., Eq.3) into the definition ...
The soil cores were sectioned at 10-cm intervals and bulk density determined. Sub-samples of approximately 10 g were used for gravimetric moisture determination, and for determination of NO3-N and NH4-N by extraction in 50 mL of 2 N KCl, shaking for 1 h (Bremmer 1965). The ...
belkae transcriptome that encode for a potential M1-type and an M3-type [FeFe]-hydrogenase, which we termed UbHydA1 (M1-type) and UbHydA2 (M3-type) (see the Section 4 for details; the sequences are provided in the Appendix A, Sequences A1). We first tested whether U. belkae ...
The fixed pancreatic tissues were sectioned (5-micron thickness) and the sections were specifically stained by the Aldehyde Fuschin procedure introduced by Gomori [25]. The stained tissue was evaluated by examination of 10 islets per group by using a Leica MZ6 optical microscope (Leica Micros...
There are certain well-defined principles in child therapeutics, which, if well understood, will make the treatment of each case a mere matter of filling in the details. I recommend the appended formula for your consideration. 1. Correct the errors in diet. 2. Correct all errors in hygiene....
