52. Parameters such as temperature, pH, and electrical conductivity (EC) were determined in situ using the HI98129 Combo Tester (Hanna Instruments, Woonsocket, RI, USA). The measurement error was from 0.5 to 5.0%, i.e. EC and DO–0.5%, pH and temperature of water–2.0%, other parameter...
Using a scratch abrasion tester (manufactured by KNT K.K.), a sample was subject to a fabric abrasion test under a load of 1 kg/cm2 for 3,000 cycles. Its contact angle with water was then measured by the same procedure as above. Example 9 A surface treating agent aqueous solution ...
Eleven populations were testcrossed with tester T1, and the remaining eight populations were testcrossed with T2, the other tester. Testcross progenies were evaluated for GY, AD and PH in four WW and three to four SS environments in Kenya and Zimbabwe in 2010 and 2011. GY in SS ...
