The rising global demand for palm oil and its associated products has led to increased numbers of palm oil refineries with its attendant effluent discharge. Many researches have confirmed the ecological disruptive potentiality of Palm Oil Mill Effluent (POME), still further attention has to be directed at POME’s potential genotoxicity. The present study has made physico-chemical and genotoxicit...
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...
We hypothesized that supplementing finishing diets with palm oil would promote adipocyte differentiation in subcutaneous adipose tissue of feedlot steers, and that soybean oil supplementation would depress adipocyte differentiation. Twenty-eight Angus steers were assigned randomly to 3 groups of 9 or 10 steers and fed a basal diet without additional fat (control), with 3% palm oil (rich in palm...
Our society faces the pressing challenge of increasing agricultural production while minimizing negative consequences on ecosystems and the global climate. Indonesia, which has pledged to reduce greenhouse gas (GHG) emissions from deforestation while doubling production of several major agricultural commodities, exemplifies this challenge. Here we focus on palm oil, the world's most abundant ve...
life table of almond moth, cadra cautella walker was studied on four main dry and semi-dry date palm varieties (deyri, zahedi, piarom, and rabbi) of iran under laboratory conditions. data were analyzed based on the age-stage, two-sex life table theory. duration of total preadult stages was 42.54, 45.79, 51.48 and 50.41 days on deyri, zahedi, piarom, and rabbi, respectively. the highest fecundit...
In this paper we propose a supervised learning system for counting and localizing palm trees in high-resolution, panchromatic satellite imagery (40cm/pixel to 1.5m/pixel). A convolutional neural network classifier trained on a set of palm and no-palm images is applied across a satellite image scene in a sliding window fashion. The resultant confidence map is smoothed with a uniform filter. A no...
Root-associating bacteria of the nipa palm (Nypa fruticans), preferring brackish-water affected mud in Sarawak, Malaysia, were investigated. In a comparison of rhizobacterial microbiota between the nipa and the sago (Metroxylon sagu) palm, it was found that the nipa palm possessed a group of Burkholderia vietnamiensis as its main active nitrogen-fixing endophytic bacterium. Acetylene reduction ...
Lowland tropical forests are increasingly threatened with conversion to oil palm as global demand and high profit drives crop expansion throughout the world's tropical regions. Yet, landscapes are not homogeneous and regional constraints dictate land suitability for this crop. We conducted a regional study to investigate spatial and economic components of forest conversion to oil palm within a ...
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...
Contactless palm vein recognition is one of the newest biometric techniques which has high level of accuracy as it is located inside the human body and does not change over the life time. In this paper, we present a rev iew of d ifferent palm vein recognition techniques that are widely used today. We mainly discuss the technical aspects of recent approaches for the fo llowing processes; identif...
