Abstract Background Various recent studies have investigated the use of traditional fibers (metallic or synthetic) as reinforcement in mortar. In times, there has been growing interest using natural cement composites. This study was conducted to assess impact date palm, doum and sisal on mechanical properties Genetic modeling chosen find shear damage at fiber-matrix interface three composites g...

In this study fourteen microsatellite primer pairs were used to study the genetic diversity of Shishi Date palm in Qatar. A total of 32 date palm (15 Shishi cultivar, 10 Khalas and seven male date palms) were collected from Qatar and 5 Shihi cultivars were collected from Saudi Arabia ‎for comparison. The Shishi set collected from Qatar was selected from ‎different regions to represent the ‎gene...

Date palm (Phoenix dactylifera L.) is a monocot, dioecious and high longevity tropical plant greatly considered due to its high economic importance in Middle East. This investigation was carried out to detect genetic relations among 34 cultivars of Iranian date palm, both males and females, using ISSR markers. Accordingly, total DNA was extracted using CTAB method and was subjected to PCR ampli...

Date bunch fading disorder (DBFD) has been one of the major issues facing date palm growers in recent decades. This order has caused high and non-compensable losses to date palm product. Despite numerous studies, predominantly focusing on the causes and mitigation methods of this disorder, no precise influencing factors have been established and practices which can completely control it are not...

the fruit of date palm (phoenix dactylifera l.) is an important horticultural product in the middle east and north africa. among more than 400 reported date palm cultivars in iran, around 20 cultivars are more important due to having better eating quality and trading values. in this study, the fruit of nine commercially important date cultivars including ‘barhee’, ‘breim’, ‘deiri’, ‘fersi’, ‘ga...

gasification is a well-known reaction owing to its relevance to generation of sustainable energyfrom biomass and development of porous carbons. the present paper attempts to experimentally investigate the kinetics of palm shell char gasification using carbon dioxide (co2) in a controlled environment using thermo gravimetric analyzer (tga) at temperatures ranging from 800 to1000°c. a relevant ki...

active carbon is char derived from pyrolysis of organic materials. it has a high porosity level and is used to filter fluids. many types of agricultural materials are used to produce active carbon. the trunk of the date palm, with its low density and high porosity, has great potential for producing active carbon. in this research, the bark was pyrolyzed at 450°c for 60 min to produce active car...
