in this research work, the effects of natural fibers such as date palm fiber (df) and jute fiber (jf) on bending properties of polypropylene (pp)/ ethylene–propylene–diene–monomer (epdm) thermoplastic elastomers are investigated. for this purpose, the date palm and jute fibers at five levels of fiber weight fractions (0, 5, 10, 20 and 30 wt. %) are utilized during composite fabrication. maleic ...
during the past two decades the use of lignocellouse fibers in reinforcing composites has attracted much research activities. in the present work, date palm fiber was used for production of composites compatible withliving environment. the fibers were pre-treated chemically to remove impurities. in order to verify and compare the effectiveness of the pretreatment methods, lignin, ash, moisture ...
Introduction: The acoustic performance of natural fiber adsorbents has been investigated in numerous studies. A part of these materials show a poor adsorption within the frequency range of less than 1000 Hz. In the present study, attempts were made to investigate the effect of layout sequence of double-layered composites consisting of natural and synthetic fibers on improving the acoustic adsor...
Abstract Background: The Date palm (Phoenix dactylifera L.) is considered an important source of food for both humans and animals in arid and semi-arid regions. The fruits contain a high percentage of carbohydrate, fat, salts and minerals, protein, vitamins and a high percentage of dietary fiber and poly phenol compounds. This study was carried out to evaluate the antioxidant capacity of met...
This study was conducted to determine the chemical composition and of silages made from Alhagi with waste date Palm. The effect of feeding different levels of ensiled Alhagi with waste date Palm on dry matter intake, nutrients digestibility and blood parameters in Kermani sheep were investigated. For this purpose 100 k g of Alhagi with 20 kg of waste date Palm without kernel were mixed and ensi...
Background and purpose: The fruit of the date palm is highly nutrient which is mentioned in Holy Q,uran for several times. In addition to being a good energy source, date contains many micronutrients, therefore, it is recommended in Islamic and traditional medicine for health and prevention of diseases. In this study we reviewed the health benefits of date according to Holy Q,uran, and Islamic ...
The final features of natural fiber composites (NFCs) depend on the integrated characteristics of their constituents. In the industry today, natural agro waste fibers are evaluated using a limited number of criteria. In this work, a combined multi-criteria evaluation stage technique (CMCEST) is introduced as a simple efficient systematic indicator to enhance evaluation of the available natural ...
date palm spider mite is one of the major pests of date palm in khuzestan.this pest damages fruits in orchards. in the present study responses of 30 native date palm cultivars of khuzestan were evaluated by assessment of pest infestation severity and fruit damage characteristics. based on the responses, cultivars were clustered into four groups as very highly infested cultivars including liloei...
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...
