Whereas most reports of the perception of outdoor hills demonstrate dramatic overestimation, estimates made by adjusting a palm board are much closer to the true hill orientation. We test the dominant hypothesis that palm board accuracy is related to the need for motor action to be accurately guided and conclude instead that the perceptual experience of palm-board orientation is biased and vari...
Oil palm is the world's leading source of vegetable oil and fat. Dura, Pisifera and Tenera are three forms of oil palm. The genome sequence of Pisifera is available whereas the Dura form has not been sequenced yet. We sequenced the genome of one elite Dura palm, and re-sequenced 17 palm genomes. The assemble genome sequence of the elite Dura tree contained 10,971 scaffolds and was 1.701 Gb in l...
In order to quantify the effects of forests to oil palm conversion occurring in the tropics on land–atmosphere carbon, water and energy fluxes, we develop a new perennial crop sub-model CLM-Palm for simulating a palm plant functional type (PFT) within the framework of the Community Land Model (CLM4.5). CLM-Palm is tested here on oil palm only but is meant of generic interest for other palm crop...
the purpose of this research was identifying factors affecting the development of processing and complementary industries of date palm in khouzestan province. the method of research was causal comparative. the population of this research was managers in processing and complementary industries of date palm products of khouzestan province (n=100). the return rate was 94% (n=94). by census method...
in order to evaluate the possibility use of palm waste cellulose as a substitute substrate for growing pot plants, an experiment was conducted in completely randomized block design with 6 replication and six treatments on aglaonema sp. the treatments were 5 levels including 0, 25, 50, 75 and 100 palm celluloid wastes mixed with different rates of some amendments such as peat, coconut coir, perl...
The inexorable expansion of oil palm plantations has been a major driver of biodiversity loss in the tropics. This is particularly evident in Malaysia and Indonesia, where the majority of the world’s oil palm is cultivated. In Latin America oil palm acreage has also been steadily increasing, especially in countries such as Colombia, the largest producer by far. However, information on the biolo...
More than half the world's rainforest has been lost to agriculture since the Industrial Revolution. Among the most widespread tropical crops is oil palm (Elaeis guineensis): global production now exceeds 35 million tonnes per year. In Malaysia, for example, 13% of land area is now oil palm plantation, compared with 1% in 1974. There are enormous pressures to increase palm oil production for foo...
Wildlife campaigners are hoping to do a deal with the burgeoning oil palm industry in Borneo in the hope of creating a forest framework to save the threatened orang-utan. Palm oil companies and the Sabah government in Borneo have agreed to a project to create wildlife corridors that will link forest areas and create a network of safe havens for the ape. Palm oil companies and the Sabah governme...
Over recent decades oil palm plantations have rapidly expanded across Southeast Asia (SEA). According to the 10 United Nations, oil palm production in SEA increased by a factor of 3 from 1995 to 2010. We investigate the impacts of current (2010) and future (2020) oil palm expansion in SEA on surface-atmosphere exchange and the resulting air quality in the region. For this purpose, we use satell...
