An study to produce cellulose nanocrystals (CNCs) from oil palm empty fruit bunch (OPEFB) was presented through hydrothermal proses and sonication pretreatment. The influence of molarity, reaction time acid ratio were studied the yield, crystallinity, chemical structure resulted CNCs. Hydrolysis at temperature 110°C using catalyst hydrochloric 1 M, with hour, 2 hour 3 hour. highest yield up 48,...

abstract temperature is the most important environmental factor that affects flowering and fruiting. the temperatures induce reproduction and cause damaging to tree or its crop.this paper analyzed daily minimum temperatures 0.0oc, and maximum temperatures 12.5 oc from october 1 to may 31 at nine sites in olive producing and cultivating regions, and one control station, using thermal adaptabilit...

The average ridge distance of "ngerprint images is used in many problems and applications. It is used in "ngerprint "lter design or in identi"cation and classi"cation procedures. This paper addresses the problem of local average ridge distance computation. This computation is based on a two-step procedure: "rst, the average distance is de"ned in each signi"cant portion of the image and then thi...
