This paper reports measurements of land-atmosphere fluxes of sensible and latent heat, momentum, CO(2), volatile organic compounds (VOCs), NO, NO(2), N(2)O and O(3) over a 30 m high rainforest canopy and a 12 m high oil palm plantation in the same region of Sabah in Borneo between April and July 2008. The daytime maximum CO(2) flux to the two canopies differs by approximately a factor of 2, 120...
Tropical agriculture is expanding rapidly at the expense of forest, driving a global extinction crisis. How to create agricultural landscapes that minimise the clearance of forest and maximise sustainability is thus a key issue. One possibility is protecting natural forest within or adjacent to crop monocultures to harness important ecosystem services provided by biodiversity spill-over that ma...
Red palm oil (Elaeis guineensis,RPO) is nutritionally rich and unique in comparison with other edible oils as it has a high content of b-carotene (400 ppm).It is the ideal choice for combating vitamin A deficiency in developing countries. The Modified Relative Dose Response test was conducted to assess the vitamin A status of school children fed RPO in the form of a sweet snack supplying the RD...
The results of an experimental work carried out to evaluate the effect of palm oil methyl esters, also known as palm oil diesel (POD) and its emulsions as alternative fuel on unmodified indirect injection diesel engine's wear and lube oil performance are presented in this paper. Half throttle engine with constant 2500 rpm setting was maintained throughout the wear debris and lube oil analysis s...
در این مطالعه پس از تعیین غلظت مناسب ال- کارنیتین بر رشد و تکثیر سلول ها با استفاده از آزمون mtt (متیل تیازول تترازولیوم)، اثر ماده ال-کارنیتین به عنوان یک آنتی اکسیدان در غلظت های به دست آمده بر پیری mscs مشتق از بافت چربی رت به روش رنگ آمیزی بتاگالاکتوزیداز مورد بررسی قرارگرفته و سپس پتانسیل تمایزی این نوع سلول ها به بافت استخوان و چربی با استفاده از روش rt-pcr و همچنین رنگ آمیزی های oil red ...
The utilities of AIRSAR data for oil palm biomass inventory and mapping are investigated. The study is on oil palm plantations in Tapah, Malaysia. The work focuses on two main applications. First, retrieval of oil palm biomass by establishing empirical relationships between backscatter coefficient and conventional estimation of biomass based on model as well as ground data. Second, mapping oil ...
BACKGROUND Cardiovascular diseases represent an increasing share of the global disease burden. There is concern that increased consumption of palm oil could exacerbate mortality from ischemic heart disease (IHD) and stroke, particularly in developing countries where it represents a major nutritional source of saturated fat. METHODS The study analyzed country-level data from 1980-1997 derived ...
N,N'-Carbonyl difatty amides (CDFAs) have been synthesized from palm oil using sodium ethoxide as catalyst. Ethyl fatty esters (EFEs) were produced as a by-product as well as glycerol. The synthesis was carried out by reflux palm oil and urea in presence of ethanol. In this process, palm oil gave 79% pure CDFAs after 8 hours and molar ratio of urea to palm oil was 6.2: 1 at 78 degrees C. Both C...
Data for this study were obtained with the aid of structured questionnaire. A total of 70 questionnaires were administered to the palm oil farmers/ producers with the response rate of 95.71 %. The data were analysed by the use of descriptive statistics, multiple regression and costs and returns tools. The results obtained revealed that although mechanized palm oil processors were not fully econ...
Iodine value (IV) is used as a parameter in process control as well as a quality parameter in traded palm oil products. IV measures the number of double bonds in the molecular structure of an oil. To form a double bond, carbon requires more energy (615 kJ/mol) than to form a single bond (350 kJ/mol). Therefore, the thermal behavior of an oil could reflect its iodine value. This study was conduc...
