The ability of a newly developed independent passive optical system OPTIMEX to measure the detonation front curvature is demonstrated on charges of pressed explosive A-IX-1 (RDX/ceresin-stearin mixture with 95/5 wt.%). The charges, with length to diameter ratios of from one to four, were prepared from cylinders with diameters of 21 mm, 30 mm, 40 mm and 50 mm pressed to a density of 1.66 g/cm3. ...

The oil palm, Elaeis guineensis, is the source of palm oil – the ‘tropical golden oil’. Malaysia is the world’s largest exporter of this golden oil. Palm oil is a versatile oil with a wide range of uses in food and nonfood areas. Triglycerides constitute the major component of crude palm oil, with smaller proportions of diglycerides and monoglycerides. The oil also contains other minor constitu...

Hydroponics culture have many advantages such as increased yield, health and uniform product, conservation of water and land , better protect , control of environmental pollution and reduce of workers for cultivation. So in recently years, usage of organic and inorganic substrates obtained more important for greenhouse owners and researchers. The aim of this study was Effects of culture substra...

Oleochemicals refer to chemicals from natural oils and fats of both plant and animal origins. However, they also include those derivatives derived from the subsequent modification of carboxylic acid group of fatty acids by chemical or biological means, and other compounds obtained from further reactions of these derivatives. Prior to 1980, about 90% of the raw materials for oleochemical industr...

macro and micromorphological investigations were conducted on selected xerepts soils from southern iran to identify changes in soil characteristics with time. soil samples from similar pedons of four irrigated orchards ranging in age from 20 to 100 years were studied and compared with soil samples of a pedon of non-irrigated land. in addition to routine analyses, undisturbed blocks of soils...

Compressed wood, which is formed by a process that increases the wood’s density, aims to improve its strength and dimensional stability. Compressed wood can be used in building and construction, especially for construction of walls and flooring. Currently, supplies of wood are becoming limited, and the oil palm tree has become one of the largest plantation species in Malaysia. Oil palm trunk co...

The objective of the study was to determine the chemical composition and nutritional value of palm pollen grains. The proximate chemical composition, vitamin, mineral, amino acid and fatty acid contents of palm pollen grains were analyzed. The results obtained showed that the values of the proximate chemical composition of palm pollen grains were moisture (28.80%), ash (4.57%), crude fiber (1.3...

Many major corporations and countries have made commitments to purchase or produce only "sustainable" palm oil, a commodity responsible for substantial tropical forest loss. Sustainability certification is the tool most used to fulfill these procurement policies, and around 20% of global palm oil production was certified by the Roundtable on Sustainable Palm Oil (RSPO) in 2017. However, the eff...

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...
