The Effect of Oil and Filer Contents on the Porosity of Lead Acid Battery Separators Produced From Polyethylene
...Show More Authors

                In this investigation a high density polyethylene (HDPE) was used as a substitute to polyvinylchloride in the production of lead acid battery separators. This has been achieved by preparing mixtures of different percentages of the feed materials which include a high density polyethylene (HDPE) locally produced, filler materials such as silica and oils such as dioctylphthalate (DOP) or paraffin which were added to the mixture to improve the final properties of the separator. The materials were compounded by two roll-mills under the same conditions. The following parameters are involved:                    

    1- Studying the use of a high density polyethylene as a binder to film components with     (15-30) wt.%.

    2- Studying the use of finely divided silica sand with (25-45) wt.% as a medium to oil adsorption.

3- Studying the use of two type plasticizers (Paraffin or DOP) with    (35-55) wt. %. as a creative medium to films porosity.

The best results of the feed materials in the mixture were selected so as to give the highest porosity using 15 wt. % PE, 30 wt. % filler, and 55 wt. % oil. It has been found that the films with DOP oil give higher porosity.

Semiotic criteria for analyzing religious symbols in press reports Qantara news site as a model

The report includes a group of symbols that are employed within a framework that gives a language of greater impact. This research discusses the problem of the semiotic employment of religious symbols in press reports published in the electronic press across two levels: Reading to perceive the visual message in its abstract form, and the second for re-understanding and interpretation, as this level gives semantics to reveal the implicit level of media messages through a set of semiotic criteria on which it was based to cut texts to reach the process of understanding and interpretation.
