Cigars were one form of Native American tobacco use observed by Columbus and early European settlers. A long, thick bundle of twisted tobacco leaves wrapped in a dried palm or maize leaf was used by Native Americans as a primitive cigar. Smoking of cigars is recorded on artifacts of the Mayas of the Yucatan region of Mexico, and the Mayan verb “sikar,” meaning to smoke, became the Spanish noun ...

Biochar was prepared by the hydrothermal carbonization (HTC) of palm leaves, characterized, and utilized as an adsorbent for Malachite Green dye (MG). The Higher Heating Value (HHV) biochar depends on temperature has a maximum value 24.81 MJ/kg. Activation using H2O2 oxidation HTC at 208 °C produced AHTC with improved capacity. optimum pH found to be in range 7–8. Freundlich, Langmuir, Temkin, ...

Mantled fruits as a result of somaclonal variation are often observed from the oil palm plantlets regenerated via tissue culture. The mantling of fruits with finger-like and thick outer coating phenotypes significantly reduces the seed size and oil content, posing a threat to oil palm planters, and may jeopardize the economic growth of countries that depend particularly on oil palm plantation. ...

Palms (Arecaceae) are prominent elements in African traditional medicines. It is, however, a challenge to find detailed information on the ritual use of palms, which are an inextricable part of African medicinal and spiritual systems. This work reviews ritual uses of palms within African ethnomedicine. We studied over 200 publications on uses of African palms and found information about ritual ...

Date palm seedlings derived from Jihel (JHL), a susceptible cultivar to Bayoud disease (fusariosis caused by Fusarium oxysporum f.sp. albedinis, Foa), were subjected to root inoculation with an arbuscular mycorrhizal fungus (AMF) collected from south Morocco and multiplied on barley as host plant. Successfully colonized plants by mycorrhizal fungi (85 % of treated plants) produced typical intra...

Most hamadryas baboons rely on Acacia species for subsistence in their semidesert habitats. Unlike other hamadryas sites, palm forests at Filoha in Awash National Park, Ethiopia, provide the baboons with a preferred food resource close to a commonly used sleeping site. The baboons are expected to feed on doum palm trees when fruit is available, and this resource use should play a role in rangin...

Palm leaf character recognition is an area which is at the nascent stage of research. Although character recognition is a well-known application of pattern recognition, lot of work is still to be exploited in handwritten character recognition. The recognition accuracy as per the literature survey for handwritten English characters is very low and for Indian languages it is just started. Researc...
