Two aphorpine alkaloids, (+)-lirinine 1 and (+)-lirioferine 2 and two bezylisoquinoline alkaloids (+)-reticuline 3 and (-)-N-Methylisococlaurine 4 were isolated from bark of Cryptocarya crassinervia. The structures were elucidated by spectral…
Screening of candidate tolerant potato (Solanum tuberosum L.) to drought in vitro from callus was aimed to determine the growth and proline content of potato plants. This research was conducted at the Laboratory of Tissue Culture of Dinas Pertanian…
Photosynthesis is the fundamental basis in green plants, and the principal organ of photosynthesis is leaf. On the basis of water requirements or adaptations, as angiosperm leaves, Anthuriums require abundant soil water and relatively humid…
Rotor systems have been widely used in mechanical applications in industry andeven in daily live equipments. The motion effects of the rotor in certain cases can cause discomfort to the user even can cause of failure to the system itself. Therefore…
This paper presents the results obtained from the application of computational fluid dynamics (CFD) to modelling the flow field of a Lapple cyclone and to optimizing the cyclone based upon its geometrical parameters. A pre-processor software GAMBIT…
Heavy metals have widespread industrial uses and have been found in increasing quantities as contaminants in all components of the biosphere. Water and sediment of rivers near industrial areas such as the Juru River in Penang and Langat River in…
It is not necessary to point out that no textbook is flawless. Each and every textbook has a number of potential strengths as well as limitations within its contents or its application in the teaching learning process. This research covers the…
