Perfect ternary arrays are closely related to difference sets and group invariant weighing matrices. A previous paper by one of the authors demonstrated strong restrictions on difference sets with parameters (120, 35, 10). A perfect ternary array with energy 25 and order 60 – PTA(60,25) – would obey an equation analogous to the difference set equation for (120, 35, 10). A perfect ternary array ...

A field experiment was conducted to study the consumptive use of water leaf (Talinum triangulare) on a constructed small scale combined weighing and non-weighing Lysimeter. This considered design construction lysimeter that characteristics non-weighing. The main components facility are mild steel, load cell, Arduino nano, micro secure digital (Micro SD) card, liquid crystal display (LCD) screen...

exposure buildup factors have been calculated by monte carlo method for point isotropic gamma ray sources, penetrating a two-layer spherical shield of water surrounded by lead, and the effect of bremsstrahlung radiation on buildup factors has, in particular, been investigated, the results of which are in good agreement with previous works. the buildup factors were then calculated for various co...
