    This paper deals with investigation of Partial Discharge (PD) and surface erosion endurance on Type I (organic) insulation. Considering two types of reference materials of the Kapton family, one having enhance resistance to PD (CR, corona resistant), a short-term PD test procedure using needle-plane electrodes was devised in order to get fast characterization of the capability of an insulating material to endure PD. Partial Discharge data and surface erosion were acquired and measured hourly, in order to obtain both a life line plot and a time behaviour of the erosion depth. Life lines were also obtained through accelerated electrothermal life tests, using cylindrical-shape electrodes. The results show significantly different PD endurance and erosion rate between the two tested materials, thus indicating that the investigated short-term procedures may be useful for the selection of insulating materials and for the estimation of the design field

    Ultra petita decision practiced under the MK’s jurisdiction to review the constitutionality of legislation needs to be assessed carefully. This practice should not be condemned as illegitimate because there is no explicit constitutional rule that guarantee it. The author therefore argues that this practice can be justified under two reasons. First, judicial activism. Second, the very nature of constitutional adjudication in order to defend the supremacy of the constitution over legislation. According to these reasons, the MK’s ultra petita decision should be upheld because this practice is the most reasonable means to protect the constitution

    There are hugh amount of traditional market organic wastes that may polute the environment. In general, the wastes are utilized for compost making and liquid fertilizer as well for plant. The use of liquid fertilizer from organic wastes of traditional markets opens up opportunities for misplaced cultivation of Setaria grass (Setaria splendida Stapf), which is required by ruminant farms. This research was conducted to evaluate the best mixture of water to the fertilizer in term of its effectiveness on the variables and experimental method using Completely Randomized Design. The treatments were: 6 doses of mixtures namely 0, 10, 20, 30, 40 and 50 liters of water, each of which was mixed with 10 liters of liquid fertilizer. The variables measured were the height, the numbers of tillers, the numbers of leaves, and canopy. The results of the study showed that the doses of water in the fertilizer did not indicate any significant differences (P > 0.05) on all variables being studied, however, the linear equation showed that greater concentrations of water in the fertilizer tended to decrease the growth of Setaria grass. Suggested use of water on the liquid fertilizer mixture should be not greater than 30 l – 10 l fertilizer
