corresponding author.
After final acceptance; the paper will
be published with indication of the first date of receipt, and
date of acceptance after revision.
Preliminary fees of 50 L.D. ( or the
equivalent in US$ ) should be paid with the first presentation

Scope:
Journal of Science and its
Applications is an annual multidisciplinary periodical that
publishes scientific contributions in pure and applied sciences.
Articles, Notes, Communications,
and Comments are published in this Journal. Articles should
cover the subjects with thoroughness, clarity, and completeness.
Authors should make their articles concise and avoiding
unnecessary historical background. Articles should have an
abstract briefly stating the objectives, significant results and
discussions, and major conclusions of the paper. The abstract
should not exceed 100 words.
Notes should represent shorter
reports in full of a significant work on a more limited subject
matter than articles. It should not exceed 3 printed pages.
Notes are not preceded by abstracts. Communications should
report preliminary results whose immediate availability to the
scientific community is deemed important. It should not exceed 4

quarto paper of adequate density good quality printouts with a
font size of 12 pt are required. The printed area for all page,
is restricted to 23cm x 16cm, with equal margins. Pages should
be left without printed numberes.However,all pages should be
consecutively numbered in pencil on the back side.
The text should be single spaced
throughout, including references, figure legends, table
captions, and footnotes; while paragraphs are separated by two
blank lines. Five spaces should be indented in the first line of
each paragraph.
SI units should be used. Chemical
formula and nomenclature must be unambiguous and in accordance
with the relevant international recommendations. Abbreviations
and uncommon symbols should be explained at first mention.
All equations and reactions must
be numbered sequentially in Arabic numerals in parentheses on
the right-hand side of the page. Words should not be underlined
for emphasis.

Composition of the Manuscripts:
The title page should
contain: the name (s) of the author (s), with all first names
written out; the institute (s) at which the work was carried
out, with all author affiliations indicated; the author to whom
correspondence is to be sent; telephone, fax numbers and e-mail
addresses.
The title of manuscript should be
centered at the width of printing area. It should be written in
bold letters with the first letter in each word in Capital.
After blank line the author(s) initial(s)
and surname(s), without titles, are written, centered in bold
letters.
In the following line, the name and
address in which the work has been done is written and
centered in italic letters.

After two blank lines, an abstract should
be given under the heading ABSTRACT. It should be no longer than
20 typewritten lines. It should be a summary of the whole paper,
not the conclusions alone. The width of the abstract area is
only 14cm. It should be centered and written in bold letters.
A blank line is left and then 3 to 5 Key Words should be
written in bold italic letters. They should not simply be taken
from the title. They should represent the content of the whole
article and be characteristic of the terminology used within the
particular field of study.
ABSTRACT
Radiative degradation curve of xantnan gum in aqueous
solution has been reported……………………………
Key Words: Gamma radiative degradation; Density and solution
viscosity;Schulz-Baschke equation.
                           
After an empty line, the manuscript itself
should start under the headings: INTRODUCTION, EXPERIMENTAL,
RESULT and DISCUSSION, and CONCLUSION.
The main headings should be centered and,
each, followed by an empty line. They should not be numbered or
underlined and they should be written in bold capital letters.

INTRODUCTION
Xanthan gum is a water soluble
anionic bacterial polysaccharide (Glass,1986). Such type of
polymers are oftenly undergo radio-rheological change when
expose to gamma radiation (O′Donnell,1989; Sangster,1989;
Shalaby,1989).
......................................................................
                         
EXPERIMENTAL
Powder Material and Mother Solution:
The powder material of xanthan was supplied by local Libyan company (JOWF)
...........
                         

RESULT AND DISCUSSION
The measured and calculated
results are given in Figs. 1,2,3 and 4 and Table 1. The
variation in efflux time of xanthan solution with the exposure
time of irradiation in Fig. 1 demonstrates the progress of
gamma session on the polymer chain ( El-Ashhab, Sheha,
Zubeir, El-Dali, & Eid,2002
). The degradation curve suggests that the irradiation had a
very marked session – in effect up to 330 min, whereas no more
effect is observed after such exposure time.……………………

Furthermore, the main sections
should be in the sequence of INTRODUCTION < EXPERIMENTAL <
RESULT and DISCUSSION. In addition, the introduction should be
clear and brief and should include the relevant references. In
the experimental section all materials used and the methods by
which the results were obtained must be clearly and concisely
described; while the conclusion should stress the major
findings, outlining their significance and indicating any
possible future applications.
All publications cited in the text
should be presented in a list of references following the text
of the manuscript. In the text refer to the author’s name
(without initial) and years of publication.
The subtitles should be written in
bold letters, left justified, and preceded by an empty line.
Figures and tables should be
embedded in the text as long as they do not occupy full pages.
The figures should be drawn with captions, written in the same
foot of the text, and centered at the width of printing area as
the rest of the text. They should be of just the right size to
show the details mentioned in the text; while each table, with
its own caption, should be written in the same font as the rest
of the text.
