Optimal reactive power dispatch (ORPD) in a typical system is complicated multi-objective optimization problem. The proper modeling of the problem has significant impact on operation and control. In this paper, an Improved Heap-based optimizer (IHBO) proposed to improve performance recently published technique called (HBO). addition, two algorithms based original HBO IHBO are developed for solv...

susceptibility test were performed on Mueller-Hinton agar with 5% horse blood according to NCCLS recommendations with the following discs: cefuroxime (30/jg), ceftizoxime (30 fig), cefpodoxime (30 /ig), cefixime (30 fig), cefaclor (30 ug) and loracarbef (10 and 30/ig). Agar and discs were from Sanofi Diagnostic Pasteur (Marnes-la-Coquette, France) except loracarbef prepared from standard refere...

Abstract Oil palm plantation (OPP) expands to soil with less suitable including Ultisol. The purposes of this study were (1) compare some selected properties among various OPP ages and (2) determine the correlation properties. A Completely Randomized Block Design single factor treatments oil age consisting 2-yr, 3 -yr, 4-yr, 8-yr, 32-yr OPP, all was repeated three times. Blocking based on floor...
