The need to mechanize major field operations that are labor intensive in oil palm industry of Malaysia has led to the study on agricultural machine *** general,study was on machine automation to reduce the number of workers required for harvesting as well as to provide comfortable ergonomic for the operator of oil palm *** objective of the study was to perform interfacing between the oil palm tree and hardware(harvester)as well as to compare the harvesting efficiency between the mechanical and automated *** analysis was calculated based on the D-H configuration for the position and orientation of harvester arm using high resolution webcam and ultrasonic sensor to obtain 3D coordinates required by the D-H *** Circuit Board(PCB)design and fabrication as well as testing and implementation of concept of camera vision operation system for FFB harvester with fully developing a Graphical User Interface(GUI)was conducted to assist the automation of the harvester *** automation of 5DOF manipulator harvester operation proves to be faster than the manually operated mechanical harvester with an approximation of 60 percent significant decrease in speed of the manipulator with 70 percent of accuracy.

The apparent solubility controls the initial stage of supercritical fluid extraction of natural products, which is most important for the process economics. Based on the literature, data on CO2 apparent solubility of volatile substances from different matrices as leaves, flowers, rhizomes and seeds were collected and compared with their thermodynamic solubility. The adsorption isotherm derived by del Valle and Urrego as a modification of the isotherm proposed by Perrut et al. is universal enough to interpret these data as well as the apparent solubility of vegetable oils from seeds, for which it was originally proposed. When the apparent solubility of minor extract components in CO2 is compared with their thermodynamic solubility, their fraction in the extracted mixture should be taken into account.

Acute hepatitis is a very rare, but potentially fatal, adverse effect of intravenous amiodarone. We present a case of an 88-year-old man with history of ischemic dilated cardiomyopathy and severely depressed left ventricular function that was admitted to our coronary care unit with diagnosis of decompensated heart failure and non-sustained ventricular tachycardia. A few hours after the beginning of intravenous amiodarone he developed an acute hepatitis. There was a completely recovery within the next days after amiodarone withdrawn and other causes of acute hepatitis have been ruled out. This case highlights the need for close monitoring of hepatic function during amiodarone infusion in order to identify any potential hepatotoxicity and prevent a fatal outcome. Oral amiodarone is, apparently, a safe option in these patients.
